The Impact of Unethical Leader-Requests on Employees' Anger, Anxiety, and Family Lives
Qiu, Feng
Wagner, David
Emotions
Unethical Leadership
Work-family
This dissertation aims to explore the potential non-work consequences of unethical leader-requests. Specifically, it examines how unethical leader-requests can trigger anxiety and anger in employees, which in turn harmfully influence employees’ insomnia, emotional exhaustion at home, and interactions with family members. In addition, this dissertation examines whether employees’ moral identity and responsibility displacement propensity will serve as two moderators that affect the degree to which they emotionally and behaviorally respond to unethical leader-requests. A three-wave field survey, a laboratory experiment, and an experience sampling method study were conducted to collectively improve the internal and external validity of the findings. Overall, the findings suggest that employees feel anxious and angry when they are requested by their leaders to engage in unethical behavior and that the negative emotions can spill over to employees’ family domain to harmfully impact their family lives. Implications and future directions will be discussed.

Surfzone hydrodynamics alter phytoplankton subsidies affecting reproductive output of Mytilus californianus and Balanus glandula
Salant, Carlissa
Shanks, Alan
Marine
The surf zone connects the ocean to the shore and acts as a semipermeable barrier through which food and larval resources must pass if they are to sustain intertidal populations. Where surf zones were narrow, more reflective, surfzone phytoplankton concentrations were lower than shores where surf zones were wide, more dissipative. Variations in surfzone hydrodynamics alter food subsidies, which in turn affects the reproductive output and growth of the ecologically important filter-feeders, the barnacle Balanus glandula and mussel Mytilus californianus. Spatial patterns of phytoplankton subsidies driven by surfzone hydrodynamics can vary dramatically over even small distances. These subsidies then drive growth and reproductive output of intertidal filter feeders.

The purpose of this dissertation study was to adapt, deliver, and experimentally test the effectiveness of a research-based, employment-focused group counseling intervention (OPTIONS) that was designed to improve male inmates' ability to secure employment upon release from prison. The intervention curriculum and study were modeled after similar interventions with battered (Chronister & McWhirter, 2006) and incarcerated women (Chartrand & Rose, 1996). The OPTIONS program was grounded in Social Cognitive Career Theory (SCCT; Lent, Brown, & Hackett, 1994, 2000) and comprised of all critical intervention components identified as contributing to positive career intervention outcomes (Brown & Krane, 2000). In addition, the OPTIONS intervention consisted of 5 weekly group sessions, which lasted 120 minutes, and each group was comprised of 6-7 male inmates. The intervention focused on various aspects of the job preparation process such as identifying necessary skills, obtaining information about different types of jobs, practicing for job interviews, and learning how to utilize social support. Study participants included 77 (n = 38 treatment, n = 39 control) adult male inmates housed at the Oregon Department of Corrections medium security release facility, the Oregon State Correctional Institute (OSCI) in Salem, OR. This study utilized a randomized block design, with between subjects and within subjects measurements at pretest, posttest, and one month follow-up. Participants were blocked based upon age and release date, and then randomly assigned to a wait-list treatment as usual control group or the OPTIONS treatment intervention group. Outcomes measured were job search self-efficacy (Career Search Self-Efficacy Scale, Solberg, Good, & Nord, 1994), perceived problem solving ability (Problem Solving Inventory, Heppner, 1988), and hopefulness (Hope Scale, Snyder et al., 1991). Data were analyzed using 2 (experimental group) x 2 (time) analyses of variance (ANOVAs). Results indicated that participants in the OPTIONS treatment intervention had higher career-search self-efficacy, problem solving, and hopefulness scores at posttest and follow-up than participants in the treatment as usual control group. This dissertation study was the first time a manualized, theory based employment preparation treatment intervention was adapted specifically for inmates preparing to release back to the community.

The Stories Behind the Stories: A Qualitative Inquiry Regarding the Experiences of Journalists Who Covered the Newtown Shooting
Deitz, Charles
Bivins, Thomas
The news coverage of the Newtown, Connecticut shooting brought to the fore some of the profession's most glaring deficits. On one hand, many of the published reports in the first days were full of speculation and, in some cases, falsities. On the other hand, the grieving community was invaded by a horde of reporters looking for exclusive content. The purpose of this qualitative study is to investigate the Newtown reportage through the experiences of reporters who were assigned to the event, and to discover how to improve the process and whether an ethic-of-care-based approach could be implemented. Through 6 semi-structured interviews, analyzed first through a grounded-theory mechanism and second through an ethic-of-care framework, this study proposes new practices for the handling of trauma coverage, which include maximizing resources and minimizing community invasion going forward. These recommendations point toward a rich area of curriculum development at the academic and professional levels.

Marine Mammals Before Extirpation: Using Archaeology To Understand Native American Use Of Sea Otters And Whales in Oregon Prior to European Contact

sea otters
Tribal ancestors living on the Oregon coast prior to European contact were skilled fisher-hunter-gatherers residing in a rich environment, home to diverse marine mammals. Euro-Americans over-exploited these marine mammals and drove some species to near extinction. Some marine mammal populations rebounded while others, such as the locally extinct Oregon sea otter, never recovered. Threats from hunting are past, but marine mammals on the Northwest Coast today face new challenges, and sea otters and cetaceans are foci of conservation efforts. Despite the interest these taxa enjoy in the present, little systematic study of their use by and relationship with precontact peoples in Oregon has occurred, and this dissertation addresses these gaps in knowledge.To address ancestral tribal use of sea otters and cetaceans I researched previously excavated faunal assemblages. The Par-Tee (35CLT20) and Palmrose (35CLT47) sites located in Seaside, on the northern Oregon coast, were home to the Clatsop and Tillamook at contact. Par-Tee and Palmrose were occupied at different times in the Late Holocene (~1850-1150 cal BP and ~2750-1500 cal BP, respectively). The two sites were excavated in the 1960s-1970s and contained an enormous quantity of well-preserved faunal remains. The Tahkenitch Landing (35DO130) site is located on the central Oregon coast, north of Reedsport, and was home to the Lower Umpqua Indians at contact. Tahkenitch Landing was occupied from the early to mid-Holocene (approximately 5000-3000 BP) and contained a large quantity of whale bones which were previously analyzed, but not identified to species level.
I conducted zooarchaeological analysis of the sea otters from Par-Tee and Palmrose (NISP=2992) and cetaceans from Palmrose (N=1174) and Tahkenitch Landing (N=33). With my co-authors, I analyzed ancient DNA from 20 Seaside sea otter specimens and performed Zooarchaeology by Mass Spectrometry (ZooMS) and ancient DNA identifications of 158 cetacean specimens. These analyses provided new insight regarding precontact ancestral tribal use of sea otters and cetaceans and the historical ecologies of the animals. This dissertation provides a socio-ecological dataset with implications for potential reintroductions of sea otters and the conservation of cetaceans in Oregon today.
This dissertation includes previously published and unpublished co-authored material.

Behavioral Biases in General Equilibrium: Implications for Wealth Inequality and Human Capital Formation

Chakraborty, Shankha
Behavioral economics

Inequality
Macroeconomics
My research focuses on the integration of behavioral economics into well understood general equilibrium macroeconomic models populated by overlapping generations of heterogeneous agents. Specifically, I analyze the implications of populating model economies with present-biased agents who are finitely lived, subject to idiosyncratic labor income shocks, and heterogeneous in both exponential and present-biased discount factors. My primary goal is characterizing the contribution of behavioral biases towards resolving several issues in the literature pertaining to human capital investment and aggregate wealth inequality. Further, the inclusion of present bias in carefully calibrated model economies allows me to rationalize empirical differences in consumption, wealth, and education that arise between observationally similar households that models of homogeneous, exponential discounters are unable to match.

Screening
Social-emotioal problems
Investigating the psychometric properties of a screening instrument for young children is necessary to ascertain its quality and accuracy. In light of the important role culture plays on human beliefs and parenting styles, a newly translated and adapted test needs to be studied. Evaluating outcomes on a translated version of a test may reveal significant information related to cultural specifications as well as the common nature of child development.
The current study examined psychometric properties of the 48-month interval of the Ages and Stages Questionnaires: Social-Emotional Second Edition (ASQ:SE-2) and its Traditional Chinese version (ASQ:SE-TC), using item response theory (IRT). Participants in the U.S. included 3,005 young children/parents dyads; 1,455 dyads were collected to represent a Taiwanese sample.
A two-dimensional Rasch Partial Credit Model (2D-RPCM), which was determined to present a better fit than a unidimensional Rasch Partial Credit Model, was used to examine the item fit, item difficulty, reliability, and item information curves to evaluate the psychometric properties on the ASQ:SE and ASQ:SE-TC. Further, differential item functioning was conducted to examine whether items were functioning differently in the two population groups. Lastly, the differences between the distributions of children’s latent traits on the continuum of social and emotional competencies for the U.S. and Taiwanese samples were investigated.
Based on findings, the adequacy of psychometric properties is discussed, providing insight into the quality of particular items. Identified differences between the two populations are explored by reviewing literature regarding cultural comparisons of childrearing practices, parenting styles, and cultural beliefs. Future directions for research include examining the cultural equivalence between translated and original versions of other ASQ:SE-2 intervals.

Differences Amongst Three Types of Coursetakers in Career and Technical Education for Attendance and Math Achievement in High School
Childs, Regine
Hollenbeck, Keith
The purpose of this study was to analyze the differences in attendance and academic achievement amongst three groups of career and technical education (CTE) students. CTE participants were divided into three groups based on levels of CTE participation and CTE occupational focus. The three groups were (a) coursetakers, (b) explorers, and (c) concentrators. The CTE students were enrolled during school years 2010–2011 to 2013–2014 and took the Oregon Assessment of Knowledge and Skills (OAKS) math test in their junior year. The analysis revealed no significant differences amongst the three groups, p = .437. The mean attendance for 4 years was nearly 96% for explorers and just over 94% for concentrators and coursetakers. No significant differences were found amongst CTE groups for overall GPA, p = .675, and for CTE GPA, p < .086. However, differences between overall GPA and CTE GPA were significant, p < .000, favoring CTE GPA. Nonsignificant differences on the OAKS math test, p = .95, were found for the three groups. This study also revealed that students susceptible to chronic absenteeism were heavily represented amongst the study participants; thus, the results may indicate that CTE encouraged positive peer relationships, enabling a higher attendance rate and allowing the cohort to achieve slightly better GPA and OAKS math test scores than non-CTE students at this school. In particular, students who were identified as special education, minority, or economically disadvantaged did as well or better in attendance and academic achievement than did their other CTE counterparts.

Culture and Economic Growth
Thompson, Jonathan
Chakraborty, Shankha
The most fundamental question in economics is what causes some countries to prosper. An emerging literature has focused on the role of culture in determining growth. I interpret culture as "the collective programming of the mind which distinguishes the members of one group or category of people from those of another," following Hofstede. I focus on the role of culture in determining economic decision making and cooperation, with an emphasis on how cross-cultural differences in how strangers are viewed may influence economic activity by narrowing the scope of interaction.
I use modern econometric techniques and neoclassical economic models to formalize the role of culture in economic decision making and test the power of culture to explain cross-country differences in long run growth paths. Throughout my research I assume that agents behave rationally but that culture influences the expectations or beliefs they have about different activities.
Subject to the common elements above, each chapter answers a slightly different question. Chapter II focuses on how colonial history may influence decisions over risk-taking in certain countries, leading to a dearth of entrepreneurial activity. Chapter III focuses on how interactions across and between cultural groups may explain the decision of minority immigrant groups to assimilate or segregate over time and how public policy may influence this decision making. Chapter IV looks at the effect of culture through the media of trust and government. Using an instrumental variables strategy, I ask which is more important to economic development, contract quality or interpersonal trust, and find strong evidence that interpersonal trust is more important.

Effects of off-axis melt supply at fast-spreading mid-ocean ridges: A study of the 9-10n region of the East Pacific Rise

Results from a recent mid-ocean ridge tomography study along the fast-spreading, northern East Pacific Rise (EPR) reveal that the axis of mantle upwelling beneath the ridge is skewed with respect to the spreading axis, giving rise to regions of both rise-centered and off-axis mantle melt accumulation. Here, we investigate the effects of off-axis melt accumulation on the architecture of overlying crust as well as off-axis melt delivery on crustal construction along the ridge axis. We first present evidence for off-axis magmatism 20 km from the spreading center in 300-ka-old crust overlying a region of off-axis melt supply. Seismic data reveal an intrusive complex ∼2 km beneath the seafloor that is limited in lateral extent (<5 km) and comprises a melt lens underlain by low-velocity, high-attenuation crust, which provides the necessary conditions to drive off-axis volcanic and hydrothermal activity. We next present results from thermodynamic modeling that show systematic, along-axis variations in the depth of crystallization and degree of differentiation of magma produce crustal density variations of ∼0.1 g/cm 3 . These density anomalies are on the order inferred from a recent study that shows increasing axial depth along the northern EPR correlates with an increase in crustal density and offset of mantle upwelling with respect to the ridge axis. Our results, along with geophysical and geochemical data from the 9°-10°N region of the EPR, suggest that along-axis deeps correspond with magmatic systems that have significant near-Moho (i.e., crust-mantle transition) crystallization, which we attribute to off-axis delivery of mantle melt. As this investigation is motivated by the EPR tomography results, we conclude with a numerical study that examines the travel time sensitivity of Pn , a sub-crustal head wave commonly used in local travel time tomography, to crustal and mantle heterogeneity. Our results indicate that Pn travel times and Fresnel zones are insensitive to normal sub-axial crustal thickness anomalies, mantle velocity gradients and crust-mantle velocity contrast variations and that mantle low-velocity zones must be at least 3 km thick to produce significant, near-constant Pn delay times. Our data support the validity and interpretation of the EPR tomography results.

This dissertation investigates the cultural importance of the "monstrous Other" in postmodern literature, including novels from Sweden, Finland, and the United States. While the theoretical concept of "the Other" is in wide circulation in the humanities and social sciences, the concept has only recently been modified with the adjective "monstrous" to highlight a special case of the Other that plays an important role in the formation of human subjectivity. In order to better understand the representational legacy of the monstrous Other, I explore some of the principal venues in which it has appeared in western literature, philosophy, folklore, and politics. Using a Foucauldian archaeological approach in my literature survey allows me to trace the tradition of the monstrous Other in such sources as medieval bestiaries, the wild man motif in folklore and popular culture, and the medicalization of intersexual embodiment. In all cases, the monstrous Other is a complex phenomenon with broad implications for the politics of subjectivity and the future of social and political justice. Moreover, the monstrous Other poses significant challenges for the ongoing tenability of normative notions of the human, including such primary human traits as sexuality and a gendered, "natural" embodiment. Given the complexities of the monstrous Other and the ways in which it both upholds and intervenes in normative human identities, no single theoretical approach is adequate to the task of examining its functioning. Instead, the project calls for an approach that blends the methodologies of (post)psychoanalytic and queer theory while retaining a critical awareness of both the representational nature of subjectivity and its material effects. By employing both strains of theory, I am able to "read" the monstrous Other as both a necessary condition of subjectivity and a model of intersubjectivity that could provide an alternative to the positivism and binarism of normative subjectivity. The texts that I examine here reveal the ways in which postmodern reconfigurations of the monstrous Other challenge the (hetero)normativity of human subjectivity and its hierarchical forms of differentiation. My reading of these texts locates the possibilities for a hybridized, cyborgian existence beyond the outermost limits of positivistic, western subjectivity.

Biological molecular motors achieve directed motion and perform work in an environment dominated by thermal noise and in most cases incorporate thermally driven motion into the motor process. Inspired by bio-molecular motors, many other motor systems that incorporate thermal motion have been developed and studied. These motors are broadly referred to as Brownian motors. This dissertation presents simulation studies of two particular Brownian motors, the feedback-controlled flashing ratchet and an artificial molecular motor concept, the results of which not only drive experimental considerations but also illuminate physical behaviors that may be applicable to other Brownian motors.
A flashing ratchet rectifies the motion of diffusive particles using a time dependent, asymmetric potential energy landscape, and the transport speed of the ratchet can be increased if information about the particle distribution is incorporated as feedback in the time dependency of the landscape. Using a Langevin Dynamics simulation, we compare two implementations of feedback control, a discrete algorithm and a continuous algorithm, and find that the discrete algorithm is less sensitive to fluctuations in the particle distribution. We also model an experimental system with time delay and find that the continuous algorithm can be improved by adjusting the feedback criteria to react to the expected state of the system after the delay time rather than the real-time state of the system.
Motivated by the desire to understand bio-molecular linear stepping motors, we present a bottom-up approach of designing an artificial molecular motor. We develop a coarse-grained Molecular Dynamics model that is used to understand physical contributions to the diffusive stepping time of the motor and discover that partially reducing the diffusional space from 3D to 1D can dramatically increase motor speed. We also develop a stochastic model based on the classical Master equation for the system and explore the sensitivity of the motor to currently undetermined experimental parameters. We find that a reduced diffusional stepping time is critical to maintain motor attachment for many successive steps and explore an experimental design effect that leads to motor misstepping.

An Exploration of the Role of English Language Proficiency in Academic Achievement
Withycombe, Adam

Achievement

English language proficiency
Growth
Reading
The purpose of this study was to examine the relationship between English language proficiency scores as measured by the ACCESS for ELLs and achievement and growth scores on the reading subtest of the Measures of Academic Progress (MAP). The sample consisted of 2,006 3rd-5th grade English language learners (ELLs) from a large Midwestern school district. Results confirmed that an increase in English proficiency is associated with higher reading achievement scores. The unique variance explained by each of the domain scores (reading, writing, speaking, and listening) on the ACCESS for ELLs supports the use of a weighted composite score for decision making purposes. When considering within-year MAP growth by differing levels of proficiency, a curvilinear trend emerged. The two lowest proficiency groups demonstrated significantly lower reading growth than the two moderate and two highest proficiency groups. The greatest growth was seen by the two groups in the middle of the proficiency spectrum. Given the increased demands on measuring the achievement and progress of all students, including ELLs, and the use of standardized achievement scores for program and teacher evaluation, the results of this study suggest that a dichotomous classification of ELL/non-ELL might not accurately reflect the variability in growth at various levels of English proficiency. Implications for interpreting and using scores by ELLs are discussed.

Virgil's Aeneid, Book 8; An Experiment in Translation
Hamel, John
Bowditch, Lowell
Aeneid
Dryden
Latin language
semantic range
Vergil
Virgil
English and Latin, though related, are very different languages, Latin with its inflections and small vocabulary, English with its overwhelming word order and expansive lexicon. Any translation from Latin to English will necessarily involve explanatory additions to the text. This is all the more true for Latin poetry, and above all for Virgil, who manages to create surprising and moving expressions line after line. Most modern translators have aimed for a literal version of the Aeneid, at the expense of mirroring in English some of the verbal magic and power of Virgil’s Latin. Dryden and Surrey strove to imitate these Virgilian features and in so doing created living poetry in English.
This translation strives to render in English a hint of the power of Virgil’s expressions. And Virgil’s own treatment of Homer and Greek literature and the whole translation-orientated project of early Latin literature lend weight to such an approach.

By traditional economic reasoning, the production and sale of private goods is assumed to be efficient in a pure market because only the owners of privately held goods can access and enjoy them. In contrast, public goods are likely to be under supplied, because individuals can free ride on the contributions of others. Citizens can solve the free rider problem either spontaneously or through the use of coercive tools such as taxation. However, such solutions will rarely be efficient. An alternative solution, seldom studied by political scientists, is the formation of clubs. Clubs exist to provide semi-public goods to their members. If only contributing members of a club can access its product (the club good), the club should be free of the free-rider problem. Because club goods are finite and rivalrous, clubs are subject to "crowding effects"; that is, per-member benefits will decline if clubs grow too large. Clubs can minimize this crowding by limiting the size of their membership. Clubs are traditionally formulated as consumer- driven arrangements, driven solely by the wealth-maximizing preferences of their memberships and not by external concerns. In an experimental setting, this dissertation demonstrates that clubs also tolerate crowding if club membership is the sole source of some club good for otherwise excluded individuals. Club members can minimize the effects of this crowding by making multilateral promises not to overuse the club good. This means that clubs members do consider the social ramifications of the club's membership policies, and those membership policies respond to government action (specifically, the presence of other funding for excluded individuals). This has implications for both the study of clubs and the associations that resemble them: firms, coalitions, and communities.

Creating Spaces for Deep Conversations around Equity in Synchronous Online Learning Environments: A Case Study

teacher education
Distance education is a new frontier for many rural California schools. In the spring of 2020, a global pandemic caused an immediate transition to online, synchronous learning platforms for the entire state. In discussion-based classrooms, where students build learning from the material, and interaction with each other, the shift posed new challenges to educators and students. This mixed methods action research case study focused on teaching about deep, challenging issues in the area of educational equity using a web-based platform. Focusing on a Northern California University course that is a pre-requisite for teacher candidates, data were collected over the course of two semesters. Forty-eight students were surveyed regarding their experiences taking part in deep discussion around equity issues over a synchronous Zoom platform. Interviews with four instructors and seven student volunteers were conducted to add depth to the survey data. A key finding from this dissertation is that Students of Color were significantly less comfortable discussing issues of race, gender, and equity with their cameras on than were White students. Additional findings pointed to race and gender-based preferences in engagement with the class material. Data indicate that the use of a multi-component pedagogy including anonymous discussion boards, chat posts, and group breakouts is important to reaching all students when engaging an online class in discussions about race, gender, and sexuality.

'Bad Gypsies' and 'Good Roma': Constructing Ethnic and Political Identities through Education in Russia and Hungary
Dunajeva, Jekatyerina
Parsons, Craig
Education
Hungary
Identity politics
Nation-building
Roma
Russia
This dissertation seeks to unpack how the two dominant images--'bad Gypsies' and 'good Roma'--developed and are mobilized in formal and informal educational institutions in Hungary and Russia and how those are perceived by Roma/Gypsies themselves. The former ethnic category has evolved over centuries, since Gypsies were increasingly defined as the quintessential 'Other', associated with resistance to authority, criminality, lack of education and discipline, and backwardness. The latter image has been advanced over the last few decades to counter negative stereotypes latent in the `Gypsy' label. Various non-state actors are promoting a new image, that of proud, empowered, and educated 'good Roma'. Mobilization of both images is distinctly recognizable in schools--it is in formal and informal educational institutions where the 'bad Gypsy' image is most visibly sustained and reproduced, while these sites are also supposed to be indisputable tools of empowerment and positive identity building.
Relying on approximately 12 months of fieldwork in Hungary and Russia, the study pursues three goals. First, it examines the origins, institutionalization, and deployment of ethnic labels used to categorize Roma. I show that two images, `bad Gypsies' and `good Roma that are contradictory in content, were reified and essentialized. Second, it investigates the mechanisms of imbuing Roma youth with normative values of these ethnic labels in formal and informal educational institutions through school instructions, curricular and extra-curricular activities, disciplinary practices, and discourse. Third, it assesses Roma response and techniques of coping to the given essentialized images about their group identity.
Overall, the dissertation is composed of two sections: a historical and contemporary examination of Roma identity formation and ethnic labeling practices. I interrogate issues of nationhood, belonging, and identity politics surrounding the Roma minority by in depth study of identity formation and construction of exclusionary nationhood in Russia and Hungary. Any attempt to understand contemporary European political, economic, and social conditions cannot ignore the Roma, an issue that requires an urgent sustainable solution. Improving Roma living conditions and elimination of prejudice against Roma requires a holistic approach and a comprehensive understanding, which is the ambition that this study pursues.

The introduction of printing into England created new opportunities for the Renaissance poet to represent himself more forcefully as a literary artist concerned with the well-being or improvement of his culture and to make public his desire for recognition as a contributor to England's literary heritage. One of the primary ways he could do so was to create a distinctive image of himself in his printed works. He could communicate his chosen image in two ways: in a traditional way, by using the language and content of his poetry, and in a new way--primarily visual rather than linguistic--by conveying an image through textual features made possible with the advent of printing. For example, a poet could guarantee that he would receive perpetual credit for his work and he could link authorship and book directly in the consciousness of his readers by seeing to it that his name was placed prominently on the title page. He could include an address to his readers, advertize his previously published works, or give information about forthcoming books. He could define himself by using mottoes or insignia or symbolic devices. Perhaps most significantly, he could include a physical image of himself in the form of a woodcut or engraved portrait. This study attempts to enlarge our understanding of the individual author's role in shaping the Renaissance literary system by analyzing both the linguistic and nonlinguistic features of the printed texts of four Renaissance poets: John Skelton, John Heywood, Thomas Churchyard, and John Taylor. It investigates the way these poets integrated their poetry with the physical features of their printed books in order to gain widespread recognition and to persuade their readers of the value of their contributions to Renaissance literary culture.

Extending the Line: Early Twentieth Century American Women's Sonnets
Wakefield, Eleanor
Peppis, Paul
American
Modernism
Poetics
Poetry
Sonnet
Women
This dissertation rereads sonnets by three crucial but misunderstood early twentieth-century women poets at the intersection of the study of American literary history and scholarship of the sonnet as a genre, exposing and correcting a problematic loss of nuance in both narratives. Genre scholarship of the sonnet rarely extends into the twentieth century, while early twentieth-century studies tend to focus on nontraditional poem types. But in fact, as I show, formal poetry, the sonnet in particular, engaged deeply with the contemporary social issues of the period, and proved especially useful for women writers to consider the ways their identities as women and poets functioned in a world that was changing rapidly. Using the sonnet’s dialectical form, which creates tension with an internal turn, and which engages inherently with its own history, these women writers demonstrated the enduring power of the sonnet as well as their own positions as women and poets. Tying together genre and period scholarship, my dissertation corrects misreadings of Edna St. Vincent Millay, Sarah Teasdale, and Helene Johnson; of the period we often refer to as “modernism”; and of the sonnet form.

Formal Dynamics of the Eighteenth-Century Type 2 Sonata
Wright, Chelsea
Rodgers, Stephen
Galant Style
Sonata Form
Sonata form is arguably the most important form to develop in eighteenth-century instrumental music. In their 2006 treatise, Elements of Sonata Theory, James Hepokoski and Warren Darcy identify five sonata types prominent in the eighteenth century that interact with the “textbook” form taught in undergraduate classrooms today—what they call the “Type 3” sonata. Type 2 sonatas, or “sonatas without recapitulation,” are the subject of this dissertation. In these pieces, the return of the primary key near the end of the piece coincides with secondary theme material—seemingly passing over primary theme material. While the Type 2 form was extremely common in the mid-eighteenth century, its behaviors remain largely unexplored in the music-theoretical and analytical literature. The purpose of this project is to explore how features early in an eighteenth-century Type 2 movement interact with the moment of the primary key’s return later in the movement. I consider the role of main themes, cadences, and the layout of a piece’s development. Musical examples come from composers whose use of the Type 2 form is notable, from better-known composers such as Mozart and J.C Bach to lesser-known composers such as Johann Stamitz and Marianna D’Auenbrugg. By exploring how these features impact our hearing of a work’s tonal resolution, we pave the way for a deeper understanding about what makes these moments expressive and meaningful.

Jambands were born in the Haight-Ashbury district of San Francisco with the Grateful Dead, who dominated this musical genre until the mid-nineties. Jamband expert Dean Budnick coined the term shortly thereafter to describe bands that perform long, improvised jams during their live shows. As these improvised shows have increased in popularity, they have become great spectacles, featuring light shows, filmed images, dancing, storytelling, and short plays. While the performance happening inside the arena deserves study, there is an equally interesting performance that takes place in parking lots before and after the shows. This is the performance of the identity of the jamband fan. How is jamband fan performance maintained and negotiated in the environment of the jamband show? Why do people need to perform this identity? Do they resist or contribute to the society that formed this subculture? Is it possible to resist society and perform "utopia," or are these fans' philosophies and styles always recuperated back into the society they try to resist? This dissertation seeks to analyze this performance as fans express behavior during pre- and postconcert activities. I will limit my study to fans of the four largest American arena jambands: the Grateful Dead, Phish, The String Cheese Incident, and Widespread Panic. While Performance Studies have sought to compare everyday life to theater, my dissertation seeks to use performance studies and subculture studies to examine whether a performance of an identity or membership within a group can be resistant to or contributing to society. This examination may help us gain a greater understanding of our social experiences.

Subacromial Shoulder Pain: A Look at Acute Muscle Pain, Acute Relief of Chronic Pain, and an Electromyography Normalization Technique
COOPER, JENNIFER
Karduna, Andrew
Shoulder pain is a common orthopedic concern. The pain has a wide range of possible causes and may progress in a number of different manners. One large gap in knowledge is the specific pathway of a chronic condition resulting from an acute injury. The purpose of this dissertation was to begin to close that gap from both ends, investigating muscular changes after acute pain is introduced and after chronic pain is acutely relieved. Additionally, an electromyography normalization technique was investigated as a means to facilitate research in a patient population. The results indicate decreases in rotator cuff muscle activity both with acute pain and the acute relief of chronic pain. This suggests acute reactions and chronic adaptations to pain differ and require further investigation.

This is a qualitative comparative study about perspectives and experiences of contemporary journalists at three newspapers in the United States and Japan. The newspaper industry in both the United States and Japan is going through an unprecedented transitional period driven by economic forces and technological changes. One purpose of the study is to shed light on everyday journalists who are exposed to industry-wide structural changes. Based on interviews with journalists of the three newspapers, this study explores journalists' experiences about economic and technological impacts and their perspectives about their work. Another purpose of this study is to compare and contrast these perspectives and experiences. By doing so, it is possible to examine how the interconnected economies of the countries and globally standardized technology influence the views and behavior of U.S. and Japanese journalists. Journalists of the three newspapers are confronting a dilemma between their journalistic ideals and increasing economic pressures that limit their activities. They are increasingly feeling insecure about employment in the newspaper industry. They show different attitudes toward employment with their newspapers.
Journalists at the U.S. newspaper think of changing careers for better job security, while Japanese journalists seek solutions within the company, rather than leaving. This indicates that U.S. journalists have more freedom to choose, while Japanese journalists are bound to their company partly because of hiring and training practices specific to Japanese newspapers. Journalists have contradictory views about technological development. While they appreciate increased productivity brought by digital technology, they feel their labor has been cheapened partly because of the same technology.
Similarities in journalists' experiences beyond newspapers and national borders occur as a result of homogenous impacts of interconnected economies of the two countries and globally standardized technology. However, shared ideas, values and norms specific to the workplace play an important role in determining journalists' perspectives and social behavior. This is why journalists' perspectives and attitudes vary by newspaper.
This study concludes by emphasizing the importance of labor studies of newspaper journalists as information providers who are expected to make democracy function.

Baryons in the Intergalactic Medium: A Hubble Spectroscopic Legacy Archive Search
Brunnenmeyer, Trevor
Bothun, Greg
Galaxies are not closed systems but are constantly interacting with their environment which generally contains a) other nearby galaxies and b) some form of warm gaseous medium existing between galaxies (known as the Intergalactic Medium or IGM). As a result, a number of physical mechanisms exist to liberate baryons (stars and gas) from within a galaxy and transfer them to the IGM. Currently there is a well-documented “missing baryon” problem in Cosmology as known galaxies do not contain enough baryons to be consistent with Big Bang Cosmology. This implies a substantial amount of Baryons must exist in the IGM, but most of this remains undetected. Using absorption in Quasar (QSO) spectra from the Hubble Spectroscopic Legacy Archive (HSLA) we can detect individual species present in the IGM. In this work, I build up and refine a pipeline to analyze 688 QSO spectra from the HSLA. At the end of the pipeline, there are multiple possible species identifications for each absorption feature. Looking at models for the extremes of the possible absorptions puts bounds that between 1.6% and 48% of the total baryon density from Big Bang Cosmology can be found in extragalactic clouds. These results do not solve the Missing Baryon Problem, but do provide evidence that baryons liberated from galaxies could be part of the complete solution.

Myosin Dynamics in Drosophila Neuroblasts Lead to Asymmetric Cytokinesis
Connell, Marisa
Prehoda, Kenneth
Cytokinesis
Drosophila
Myosin
Neuroblast
Cells divide to create two daughter cells through cytokinesis. Daughter cells of different sizes are created by shifting the position of the cleavage furrow. The cleavage furrow forms at the position of the metaphase plate so in asymmetric cytokinesis the spindle is shifted towards one pole. Unlike most systems, Drosophila neuroblasts have a centrally localized metaphase plate but divide asymmetrically. Drosophila neuroblasts divide asymmetrically due to the presence of a polarized myosin domain at the basal pole during mitosis. I investigated the mechanism by which the basal myosin domain produces asymmetric cytokinesis and the pathway regulating this domain.
We tested several mechanisms by which the basal myosin domain could lead to asymmetric cytokinesis. Based on surface area and volume measurements, I demonstrated that asymmetric addition of new membrane is not involved. I determined that neuroblasts exhibit asymmetric cortical extension during anaphase with the apical pole extending 2-3 times more than the basal pole. Mutants that lose basal myosin extend equally at both poles supporting this model. Mutants that retain apical myosin exhibited symmetric cortical extension but still divided asymmetrically, demonstrating that asymmetric cortical extension is not required for asymmetric cytokinesis. Observations of the mitotic spindle show that the cleavage furrow forms at a position biased towards the basal pole when compared to the position of the metaphase plate even though this position is still equidistant between the centrosomes. I observed that midzone components shift basally in a basal domain dependent manner suggesting that contraction of the basal domain leads to new microtubule-cortex interactions at a position away from the spindle midzone.
I demonstrated that the basal domain is regulated by the heterotrimeric G protein, Gβ13F, which is activated by Pins. In Gβ mutants, the localization of all basal components (myosin, anillin, and pavarotti) is lost and the cells divide symmetrically. Although the basal domain is contiguous with equatorial myosin, it is not regulated by the same pathway and photobleaching experiments indicate that they exhibit different behaviors during anaphase suggesting a difference in temporal regulation.

Reconstructing the Top Quark in a Search for a Pair-Produced Supersymmetric Partner in the All-Hadronic plus Missing Energy Final State Using $139$~$\text{fb}^{-1}$ of $\sqrt{s}=13$~TeV Proton-Proton Collisions Delivered by the Large Hadron Collider and Collected by the ATLAS Detector

Top Quark
The Large Hadron Collider (LHC), the world's most powerful particle accelerator, is operated by the CERN laboratory near Geneva, Switzerland and was built to probe the tera-electron-volt energy scale in search of New Physics. ATLAS is one of several international collaborations at CERN and uses a 7,000-ton general purpose detector to collect collision data from the LHC. The top quark is the most massive particle under the Standard Model and carries the largest Yukawa coupling to the recently discovered Higgs Boson, making it sensitive to effects of heavy new physics.
Supersymmetry offers a diverse class of theoretical models providing potential solutions to the most salient phenomenological inconsistencies of modern particle physics, namely it provides a mechanism for stabilizing the Higgs boson mass while predicting the existence of several new particles at the tera-scale. This dissertation presents a search for the pair production of a supersymmetric partner to the top quark, the stop ($\tilde{t}$), using $139$~$\text{fb}^{-1}$ of proton-proton collision data collected by the ATLAS detector during Run 2 of the Large Hadron Collider (LHC) at a center of mass energy of $\sqrt{s}~=~13~\text{TeV}$.
This dissertation focuses on understanding the hadronic top decay and its reconstruction with the ATLAS trackers and calorimeters, as well as estimating the Standard Model $t\bar{t}$ background to the search in the signal regions design to be sensitive to boosted and semi-resolved top decays. The experimental signature of the search presented is: at least four jets originating from two hadronically-decaying top quarks and large missing transverse energy from the pair of stable, light, and neutral supersymmetric neutralinos ($\chi^{0}_{1}$). No excesses over the expected Standard Model predictions were observed and exclusion limits can be placed to stop masses up to 1.25 TeV, assuming a $100\%$ branching fraction of $\tilde{t}\rightarrow t\chi^{0}_{1}$.
This dissertation includes previously published and unpublished co-authored material.

Sanitizing History: Environmental Cleanup and Historic Preservation in U.S. West Mining Communities

Superfund
U.S. West
Residents in mining towns of the U.S. West face a troubling quandary in their attempts to preserve historical evidence of their town’s industrial past, because that evidence threatens their health. The 1980 Comprehensive Environmental Response, Compensation and Liability Act (CERCLA, or “Superfund”) authorizes the Environmental Protection Agency to clean up toxic sites, but these sites are often where the most marginalized residents have lived and are sometimes the only evidence of those residents. How have mining communities preserved the past while ensuring the community’s health and safety?
My dissertation, “Sanitizing History: Historic Preservation and Environmentalism in U.S. West Mining Communities,” is the first book-length study that weaves together the histories of historic preservation and environmentalism to demonstrate that the answer lies with interagency cooperation and site-specific solutions. Focusing on Butte, Montana; Globe, Arizona; and Leadville, Colorado, my study relies on a wide array of source material, including archival collections and site visits. Chapter Two shows how some narratives about mining towns, rather than boosting the towns, derided them for their physical and moral uncleanliness. Chapter Three traces Progressive Era urban reform while Chapter Four documents infrastructure modernization from the 1920s to 1940s and the resulting destruction of historical resources related to marginalized populations. Chapter Five explores redevelopment in the early postwar years. Chapter Six demonstrates how historic preservation and environmental policies coalesced in the 1960s, and Chapter Seven reveals that previously marginalized residents leveraged 1980s environmental laws to gain cleanup of mining landscapes. By employing lenses of intersectionality and agency, my project concludes that, in the process of asserting their right to bodily health and safety, mining town residents have perpetuated a pattern of forgetting that allowed cultural ills to continue. My work thus prompts scholars, activists, and members of the general public to search for policies that preserve painful pasts while allowing for healing.

Brand Mind Perception and Moral Judgments of Brand Behavior: How Perceived Leadership Influences Consumer Attitudinal Responses to a Brand's Wrongdoing
Xie, Hu
Cornwell, T. Bettina
Brand endorser
Brand mind perception
Moral judgment
Perceived leadership
How we communicate about brands and companies has changed. CEOs have come into the spotlight of brand communications but little marketing research offers holistic knowledge about CEOs as brand endorsers. This research investigates how CEO endorsers influence consumer attitudes toward a brand differently from conventional endorsers (e.g., celebrities and athletes). Further, this research examines underlying mechanisms that determine consumer responses to CEOs as brand endorsers and especially consumer moral judgments of a brand’s wrongdoing.
Building on research on brand endorsers and brand equity, as well as drawing theoretical support from research on leadership, anthropomorphism and mind perception, this dissertation proposes a moderated mediation model of CEO endorser effects on consumer moral judgments. Brand endorsers for decades have been viewed as essentially communicating via three characteristics: attractiveness, expertise and trustworthiness. This dissertation identifies perceived leadership as an additional endorser dimension elicited from a CEO-brand endorser. Further, this dissertation introduces brand mind perception into marketing research and finds that perceived leadership positively influences consumers’ perception of brand mind, which in turn determines consumers’ moral judgments. Boundary conditions are explored and include endorser-brand relationship and crisis controllability.
Two sets of studies provide empirical support. The first set defines and develops the scale of perceived leadership including item generation (Study 1), item purification (Study 2), and scale confirmation (Study 3). The second set tests the hypotheses in the conceptual model. Two exploratory studies first find preliminary evidence of that perceived leadership differs from existing endorser dimensions by its effects on moral judgments (Study 4), and that mind perception is possible for a brand and can be enhanced by CEO association (Study 5). Study 6 shows positive effects of CEO endorsers on consumer attitudes by communicating perceived brand leadership. Study 7 investigates a brand-wrongdoing scenario and shows that perceived brand leadership yields negative results for a brand by increasing blame and reducing forgiveness; Study 8 demonstrates these relationships are mediated by brand mind perception. Study 9 shows that the inspiring aspects of perceived leadership can enhance perceptions of brand mind (to feel and experience), thus reducing consumers’ blame. Theoretical and managerial implications are discussed.

School Suicide Prevention: A Breadth and Depth Perspective

School suicide prevention
The present study provides a breadth and depth perspective of the current landscape for school suicide prevention (SSP). Despite an increase in SSP programming, practices, and policy, there remains a gap in understanding of how widely these activities are disseminated and implemented. Additionally, there is a lack of knowledge around the adoption of recommended programs and practices once disseminated to school practitioners, along with what SSP-related barriers, successes, and goals that were identified and prioritized by schools. To address these gaps, a sequential mixed-methodology design comprised of two studies was conducted with a breadth-focused statewide needs assessment survey (i.e., Study 1), and a depth-focused multi-method pilot (i.e., Study 2). Findings from Study 1 indicate that SSP activity (i.e., evidence-based programs [EBPs] and recommended practices implementation) increases slightly from elementary, to middle, and up through high school; with statistically significant differences in implementation occurring for three EBPs (i.e., Mental Health First Aid [MHFA], RESPONSE, and Connect Postvention) and two recommended practices (i.e., SSP Curriculum and Guest Speakers) at the school level (i.e., elementary, middle, and high school). Additional Study 1 findings are discussed in regard to SSP activity differences across region classification and the association between SSP activity and school staff comfort level on the topic of suicide prevention. Findings from Study 2 identified clear categories and themes for SSP challenges and barriers, current successes, and prioritized goals. Study 2 also explored what key features of SSP were already being implemented within an MTSS structure. Interpretation of Study 1 and 2 findings, along with limitations, implications for practice and policy, and future research directions are discussed.

Can the United States and Russia Cooperate? Analyzing the results of bilateral and multilateral cooperation on the Syrian conflict
Ward, Peter

The discourse regarding US/Russia relations focuses intensely on the competitive nature between these two powers. Policy makers echo strategies of the past by making recommendations which embrace competitiveness and mutual mistrust as unavoidable characteristics for future relations. Although these perspectives are not entirely misled, they fall short of illustrating the finer nuances of relations. This paper offers an extensive analysis of three instances of cooperation between the US and Russia in Syria between 2011 and 2017 in order to offer concrete observations about how these antagonistic powers work together. The analysis shows that although the US and Russia are competitive and often have opposing agendas, this does not necessarily prevent them from cooperative engagement that produces substantive results. Their polarity can even contribute to more effective cooperation. This paper also draws conclusions about what circumstances improve the effectiveness of US/Russia cooperation and makes recommendations for future mutual efforts in Syria.

Nike-Apsara Imagery in First and Second-Century Gandharan Art and the Theoretical Framework of the Roman Image-Language

Nike-Apsara
Scholarship has examined the Greco-Roman deities used as prototypes for Buddhist figures in Gandhara, such as Apollo-Buddha, Tyche-Hariti, and Atlas. Minimal research has explored the surmised correlation between Nike and Apsaras. Therefore, this thesis investigates the thematic roles, iconography, and historical relationships between the two, including Roman interpretations of Nike, to expand on prior Greek and Hellenistic-centric discussions. I argue that when we look at evidence of the Apsara, such as that depicted on the first or second-century Gandharan relief in the Art Institute of Chicago, in comparison to Nike representations from the Imperial Roman period, similarities can be identified that support the notion of a correlation between the two existing in Central Asia. Further supporting this claim, I utilize the theoretical framework proposed by Stoye, which builds on Hölscher’s Roman-Image Language, to recontextualize the Apsara imagery on the Gandharan relief and explore why the Kushans viewed the figures as interchangeable or capable of being synthesized.

Patient-Centric Innovation in Service Modalities for End-Stage Renal Disease

The purpose of this study is to examine the feasibility of introducing innovative dialysis delivery methods. In the first essay, advised by Prof. Nagesh Murthy and Dr. Eren Cil, we study a new and non-traditional dialysis service modality, called a mobile dialysis clinic, that can reduce the travel burden for ESRD patients, resulting in a reduction in hospitalization costs undertaken by Medicare.To this end, we develop a framework to consider the strategic interaction between Medicare and a dialysis service provider and examine the potential benefit to Medicare for considering a “shared-savings payment policy.”
Specifically, our proposed incentive payment structure features “reward rate” as the percentage of hospitalization cost savings that the provider receives as a bonus payment for offering coverage using a mobile dialysis clinic.
We first establish that the provider undertakes the additional costs of a new modality
only when the reward rate offered by Medicare exceeds a critical level.
We, then, show that once offering the new modality becomes viable, the provider serves more patients with the new modality and consequently decreases the hospitalization costs for Medicare as the reward rate increases.
Despite the favorable effects of the new modality on the total hospitalization costs, Medicare faces a trade-off between lowering the hospitalization cost and the sharing cost savings with the provider.
Hence, we find that Medicare does not always optimally offer enough compensation to the provider to justify offering the new service modality.
However, we also identify certain conditions under which Medicare, interestingly, finds it optimal to increase the reward rate to incentivize the provider to offer a mobile clinic even when this increased reward rate results in a drastic improvement in provider’s profit with only a marginal reduction in Medicare’s cost.
We discuss the prospect of offering assisted home dialysis in the second essay to overcome the barriers to home dialysis. The second essay is advised by Prof. Nagesh Murthy and Dr. Eren Cil. Assisted home dialysis can be provided in-home or via telemedicine by a nurse. We develop a mathematical model to examine the implications of an optimal integration of new modalities, i.e., satellite clinics and nurse assisted home-dialysis into the existing dialysis network on the provider's profit and Medicare's costs. We analyze these implications under a variety of scenarios that reflect geographic dispersion of patients from the existing main clinic, patient preferences, and hospitalization cost attributed to recurring distance traveled. Our findings can help policymakers for Medicare design new policies that motivate providers to introduce new and innovative ways of offering dialysis to patients.

Neuro-imaging Support for the Use of Audio to Represent Geospatial Location in Cartographic Design

Sonification
Spatial thinking
Temporal order
Audio has the capacity to display geospatial data. As auditory display design grapples with the challenge of aligning the spatial dimensions of the data with the dimensions of the display, this dissertation investigates the role of time in auditory geographic maps. Three auditory map types translate geospatial data into collections of musical notes, and arrangement of those notes in time vary across three map types: sequential, augmented-sequential, and concurrent. Behavioral and neuroimaging methods assess the auditory symbology. A behavioral task establishes geographic context, and neuroimaging provides a quantitative measure of brain responses to the behavioral task under recall and active listening response conditions.
In both behavioral and neuroimaging data, two paired contrasts measure differences between the sequential and augmented-sequential map types, and between the augmented- sequential and concurrent map types. Behavioral data reveal differences in both response time and accuracy. Response times for the augmented-sequential map type are substantially longer in both contrasts under the active response condition. Accuracy is lower for concurrent maps than for augmented-sequential maps; response condition influences direction of differences in accuracy between the sequential and augmented-sequential map types. Neuroimaging data from functional magnetic resonance imaging (fMRI) show significant differences in blood-oxygenation level dependent (BOLD) response during map listening. The BOLD response is significantly stronger in the left auditory cortex and planum temporale for the concurrent map type in contrast to the augmented- sequential map type. And the response in the right auditory cortex and bilaterally in the visual cortex is significantly stronger for augmented-sequential maps in contrast to sequential maps. Results from this research provide empirical evidence to inform choices in the design of auditory cartographic displays, enriching the diversity of geographic map artifacts.
Four supplemental files and two data sets are available online. Three audio files demonstrate the three map types: sequential (Supplementary Files, Audio 1), augmented- sequential (Supplementary Files, Audio 2), and concurrent (Supplementary Files, Audio 3). Associated data are available through OpenNeuro (https://openneuro.org/ datasets/ds001415).

Toward Empowerment: Women and Community-Based Tourism in Thailand
Dunn, Susan F.
xi, 75 p. : ill., maps. A print copy of this title is available through the UO Libraries under the call numbers: KNIGHT G155.T5 D86 2007
In recent years, tourism has garnered widespread support as a tool for sustainable development. Alternative forms of tourism have emerged such as ecotourism, pro-poor tourism, volunteer tourism, and in particular, community-based tourism. While sustainable tourism development strongly emphasizes environmental issues, it seems that sociocultural issues have been overshadowed. Gender·considerations need to be included in a critical analysis of the sociocultural impacts of these emerging forms of tourism. This research seeks to determine how a community-based tourism project promotes the empowerment of women,using a case study of one rural Thai community, Leeled. Empowerment is operationalized as a multidimensional process with political, psychological, social, and economic dimensions experienced individually and collectively. While community-based tourism projects have been successful in promoting women's empowerment, they could be more successful and improve sustainability if development practitioners would incorporate a gender analysis assessment throughout the development process.

The Information Content of Risk Factor Disclosures in Quarterly Reports
Filzen, Joshua James, 1981-
Accounting

Risk factors
xiv, 95 p.
I examine whether recently required Risk Factor update disclosures in quarterly reports provide investors with timely information regarding potential future negative outcomes. Specifically, I examine whether Risk Factor updates in 10-Q filings are associated with negative abnormal returns at the time the updates are disclosed and whether quarterly updates are followed by negative earnings shocks. I find that firms presenting updates to their Risk Factor disclosures have lower abnormal returns around the filing date of the 10-Q relative to firms without updates, although I find little evidence to suggest that the strength of this relationship is positively associated with the level of information asymmetry between managers and investors. Using analyst forecasts and a cross-sectional model to forecast earnings as measures of expected earnings prior to the release of Risk Factor updates, I find that firms with updates to their Risk Factors section have lower future unexpected earnings. I also find that firms with Risk Factor updates are more likely to experience future extreme negative earnings forecast errors. These findings suggest that the recent disclosure requirement mandated by the SEC was successful in generating timely disclosure of bad news. However, I also find some evidence that firms with updates to their Risk Factors section have stronger future positive performance shocks relative to firms without Risk Factor Updates, consistent with firms that disclose Risk Factor updates also having greater upside potential.

Third Country Study
This thesis is exploratory in nature and examines the perspective of graduate and undergraduate matriculating international students at the University of Oregon as they consider, prepare for, reflect on, and participate- or not- in study abroad programs. The three-phase model design of this study assesses the opportunities, obstacles and resources international students experience as they consider or do not consider studying abroad by analyzing online survey responses from University of Oregon graduate and undergraduate international students; quantitative data sets; semi-structured interviews with University of Oregon graduate and undergraduate international students, as well as with staff members from the Office of International Affairs.
International student areas of opportunities include receiving academic credit towards degree; practicing a language abroad; learning about new cultures; and developing new friendships. The challenges include difficulty in academic planning; limited financial resources; lack of family approval or support; and having to make difficult decisions between going abroad or visiting home. International student resources include major applicable coursework that is only open through specific study abroad programs; some available funding; and receiving practical support from staff members at the Office of International Affairs on campus. Recommendations include how international educators may be more inclusive and more sensitive to international students needs and challenges as they consider study abroad.

Ecology, Society, and Self: Toward a Multi-Tiered Framework for Participatory Approaches in Knowledge Generation
Studholme, Ashley
Lynch, Kathryn
Interdi
Participatory approaches in knowledge generation have become increasingly important in understanding our environments and integrating human and natural systems. Such approaches have been used to discover new species, address environmental injustices, and develop land management practices. However, frameworks and models used to explore participatory approaches tend to be oversimplified or focus on a specific component. Here, I present an integrated multi-tiered framework to gain insight into how project context and design interact to create outcomes that shape the socio-ecological system. The framework accounts for the nested scales, i.e. ecological, societal, and individual, of both the context and the outcomes. I then demonstrate the utility of the framework by applying it to two case studies in Ecuador: 1.) a climate change monitoring network and 2.) Andean bear para-biologists. Using this framework, it was evident that in both projects, gendered landscapes and how participants engaged were primary factors in shaping outcomes.

Race and ethnicity
This project is based on an ethnography of Trifecta Tech (pseudonym) a major high-tech firm on the West coast of the U.S. Although a growing group of organizational theorists started investigating high-tech firms’ organizational model and management mechanisms, they are still limited by their neglect of two latest trends in the high-tech industry: the rejuvenation of the workforce through disproportionally recruiting young college-educated men and the masculinization of the organizational culture. Drawing on 46 in-depth interviews and 11 months of participant observation, this study argues that these two latest dynamics result in some significant organizational processes that have not been examined before, including the gamification of the workplace; the promotion of “playful” organizational culture that attempts to blur boundaries between work and off-work activities; and the reinforcement of masculinized racial hierarchy to facilitate managers’ division of labor.

The Development and Application of Nanohoops as Novel Fluorescent Probes for Biological Applications
Lovell, Terri
Jasti, Ramesh
Fluorescent molecules are imperative for the detection of diseases and observation of complex biological processes in living systems. A wide variety of small molecule fluorophores are available, however they each come with their limitations. An entirely new scaffold with enhanced photophysical properties, tunability, and chemical stability would be advantageous. Herein, we present our efforts in designing and applying nanohoops as novel fluorophores for biological applications.
Chapter I reviews commonly used small molecule fluorophores and how to tune their photophysical properties using physical organic chemistry concepts. Chapter II describes how to enhance the brightness of nanohoops to make them suitable for biological imaging. Chapter III demonstrates how to shift the fluorescence of nanohoops further red, which is desirable for cellular imaging. Chapter IV reports the first intracellular targeted nanohoop for live cell imaging. Lastly, Chapter V describes our efforts to broadly apply nanohoops as novel fluorophores for protein and DNA labelling. This dissertation describes the pronounced strides made towards developing nanohoops as novel fluorophores for biotechnology.
This dissertation includes previously published and unpublished co-authored material.

The current study measured BOLD brain response using functional magnetic resonance imaging (fMRI) to explore the hypothesis that women with bulimia nervosa have a hyper-responsivity of the mesolimbic reward system. Women with bulimia nervosa and healthy controls (N=24) completed an fMRI paradigm involving anticipated and actual receipt of chocolate milkshake and a tasteless control solution. Women with bulimia nervosa showed less activation than healthy controls in the right anterior insula in response to anticipatory food reward and in the left medial orbitofrontal cortex, right posterior insula, right precentral gyms, and right mid dorsal insula in response to consummatory food reward. Covariates related to bulimia diagnosis accounted for some of these effects, but not all. Results suggest that bulimia nervosa may be related to hypo-functioning of the brain reward system rather than hyper-functioning. Implications for intervention and future research are discussed.

Livelihood Strategies in China: Lessons Learned From Taiyuan
Bachrach, David
Buck, Daniel
China

Urban Studies
Studies of urban China often deploy top-down analyses and focus on tier-1 cities such as Beijing and Shanghai. This thesis contributes to a diversifying literature by using a bottom-up analysis to compare the livelihood strategies of peri-urban residents in Taiyuan, a tier-2 city, to those in tier-1 and other lower-tiered cities. The empirical findings elucidate a similar spectrum of livelihood strategies, but unlike tier-1 and some lower-tiered cities, there was an absence of renting to migrant workers in peri-urban Taiyuan. Additionally, social infrastructure, social reproduction, and socio-spatial practices, often overlooked in studies of Chinese livelihoods, are central to understanding livelihood strategies people in peri-urban Taiyuan. Lastly, this thesis suggests that similar comparative studies can produce sharper insights into how processes of urbanization are not bound to specific territories: Chinese and global urban studies are connected through analogous urbanization processes, while also having unique circumstances.

The current study used a quasi-experimental comparison group pre/post-test design to examine the effectiveness of the Language and Play Everyday (LAPE) program for improving EI/ECSE practitioners’ knowledge, use of, and confidence in using Caregiver Implemented-Naturalistic Communication Interventions (CI-NCIs). Participants included 20 EI/ECSE practitioners across IDEA-related disciplines, eight with prior LAPE experience. 10 practitioners took part in a new, more intensive LAPE program, and 10 did not. Analysis of pre/post-questionnaires revealed that practitioners with prior LAPE experience reported significantly higher use of CI-NCI skills and mean self-efficacy ratings than those without LAPE experience. Practitioners who participated in the new, more intensive program used significantly more skills and scored significantly better on a knowledge test than those who did not participate, even when controlling for prior LAPE experience. These findings indicate that the LAPE program is a promising model to train EI/ECSE practitioners across disciplines in CI-NCIs.

Behavioral and Neurobehavioral Features of "Sociality"
Lukinova, Evgeniya
Myagkov, Mikhail
Standard models of decision making fail to explain the nature of the various important observed patterns of human behavior, e.g. "economic irrationality," demand for "sociality," risk tolerance and the preference of egalitarian outcomes. Moreover, the majority of models does not account for the change in the strategies of the human beings playing with other human beings as opposed to playing against a machine.
This dissertation analyzes decision making and its peculiar characteristics in the social environment under conditions of risk and uncertainty. My main goal is to investigate why human beings behave differently in a social setting and how the social domain affects their decision-making process. I develop the theory of "sociality" and exploit experimental and brain-imaging methodologies to test and refine the competing theories of individual decision making in the context of the social setting. To explain my theory I propose an economic utility function for a risk facing decision-maker that accounts for existing theories of utility defined on the outcomes and simply adds another term to account for the decision-making process in the social environment. For the purposes of my dissertation I define "sociality" as the economic component of the utility function that accounts for social environment, a function of a process rather than of an outcome. I follow on the breakthrough work by evolutionary psychologists in emphasizing the importance of the substantive context of the social decisions.
The model I propose allows one to think about situations in which individuals may care for more than their narrowly-defined material interest and their decision may be driven by "sociality" and other non-monetary considerations. The "sociality" component of the economic utility function demonstrates the fact that individuals do not only care about outcomes but also about the processes which lead to these outcomes. In my empirical chapters I put the theory to the test in a series of laboratory experiments carried out in the United States, New Zealand and Russia and a series of fMRI and computer experiments executed at the University of Oregon.

A Survey of Photoperiodic Response and Morphological Variation Across a Latitudinal Gradient in Threespine Stickleback
Yeates-Burghart, Quick Sarah Loraine, 1979-
Sticklebacks -- Oregon -- Morphology
Sticklebacks -- Alaska -- Morphology
x, 36 p. : ill. A print copy of this thesis is available through the UO Libraries. Search the library catalog for the location and call number.
Natural biological variation exists at different geographic scales. We compared
phenotype distribution across latitude, region and habitat type in threespine stickleback
(Gasterosteus aculeatus) to determine local adaptation. To quantify variation in
photoperiodic response, the day length cue was used to time sexual maturation and
morphological characters across these various scales. Using lab-reared lines, we
developed an index of sexual maturation and experimentally determined critical
photoperiod for Alaskan and Oregon populations. Results showed that photoperiodic
response existed in Alaskan but not Oregon populations. We also collected
morphological data and made comparisons between wild Alaskan and Oregon
populations and found similarities within habitat type across latitude but differences
across region and habitat type. These data support the hypothesis that local adaptation results in variation across geography and habitat and, in stickleback, parallel evolution of
morphological phenotypes within similar but geographically distant habitats.

Late Quaternary and Holocene Paleoecology of Interior Mesic Forests of Northern Idaho
Herring, Erin
Gavin, Daniel
Biogeography
Idaho
Paleoecology
Pollen
Refugia
The mesic forests distributed within the Rocky Mountains of northern Idaho are unique because many species contained within the forest are separated from their main distribution along the Pacific Northwest coast. It remains unclear whether most species within the inland disjunction survived the glacial periods of the Pleistocene, or whether they were more recently dispersed from coastal populations. To see if the dominant tree taxa of the mesic forests today could have persisted in a refugium south of the large ice sheets, four sediment cores were used to reconstruct the vegetation and climate history of the region. A nearly continuous record of pollen and sediment composition (biogenic silica and inorganic and organic matter) over the last ca. 120,000 years provides evidence of a dynamic ecosystem. Over a long timescale, the slow shifts in vegetation are attributed to the changes in climate. During the last interglacial period, the region was warmer and drier with a Pinus dominated mixed conifer forest. Approximately 71,000 years ago, a Pseudotsuga/Larix forest became established in the area as a response to the increased available moisture. As climate cooled and glaciers expanded the Pinus and Picea forest was the dominant vegetation type until ca. 40,000 years ago. The environment during the Last Glacial Maximum (LGM) was so harsh that no vegetation record was recorded. After the LGM, climate warmed, enabling a Pinus and Picea forest to establish and persist until the Holocene.
The mesic taxa that dominate the modern forests did not arrive in northern Idaho until the mid- to late-Holocene. The recent arrival of the dominant tree species, Thuja plicata and Tsuga mertensiana, suggests that they likely did not persist in a refugium during the last glaciation. Instead, these species recently dispersed from coastal populations, but expansion into their interior distributions was likely limited by both climate and species competition in already established forests. During the late-Quaternary, the deposition of thick tephra layers (>20 cm) from the eruptions of Glacier Peak (ca. 13,400 years ago) and Mt. Mazama (ca. 7,600 years ago) also facilitated an abrupt and persistent change in vegetation in northern Idaho.

Crime Fiction of Crisis: New Neo-Realism in the Age of Berlusconi from 1990 to 2010
Antonelli, Antonella
Lollini, Massimo
This dissertation focuses on selected crime novels by Grazia Verasani, Elisabetta Bucciarelli, Carlo Lucarelli, Luciano Marrocu, Massimo Carlotto and Giancarlo De Cataldo written between 1990 and 2010, the years known as the era of former Prime Minister Silvio Berlusconi, an age that is symbolic, among other things, of disrespect and affront to democracy, of reinforcement of sexism, control of the media, controversial legitimizing views of Fascism, impudent corruption, attempts to change and create laws for personal advantage, and collusion with Mafia.
My work shows that these novels are romanzi sociali that continue the tradition of social commitment of Italian crime fiction began with Augusto De Angelis in the 1930s and then developed by Giorgio Scerbanenco, Loriano Macchiavelli and Leonardo Sciascia.
The novels I analyze are a commentary on the country's current crises, such as the status of women, the objectification of the female body and the increase of violence against women (Verasani and Bucciarelli).
My study also explores how historical crime fiction brings attention to the issue of historical revisionism that characterized the rise to power in 1994 of Berlusconi's Forza Italia and exposes the mythology of the innocent Fascist and the good-hearted Italian regarding the responsibilities of Italian colonialism (Lucarelli and Marrocu).
Finally, in an era characterized by the lack of freedom of the press, some of these novels act as a counter-information tool on hot issues such as the collusion with the institutions and organized crime and the web of powers that shaped postwar Italy, and they demythologize the image of northeastern Italy, described as the engine of Italian economy, by exposing its corruption and illegal business with organized crime (De Cataldo and Carlotto).
Ultimately, this dissertation shows the potential of crime writing as a genre suitable to perform social criticism and to involve a more socially and politically conscious readership.

This research develops Broom, Casey and Ritchey's (1997) concept of relationship antecedents, suggesting moral obligation as a non-consequential relationship antecedent. By using Bivins's (2009) classification of moral and functional obligations, this research suggests that nonprofit managers perceive a moral obligation on the part of gaming corporations to establish relationships that can benefit the local community. Where a functional obligation would affect the corporation's ability to do business, the moral obligation is non-consequential and falls outside the parameters of the six consequential relationship antecedents identified by Grunig and Huang (2000).
Business ethicists have long debated the need for corporate social responsibility, broadly defined as the idea that a corporation has a responsibility to society separate from its profit-making obligation to stockholders. This research looks at corporate social responsibility in the gaming industry in Las Vegas, examining nonprofit managers' expectations for these corporations to contribute to the local community. This study examines through qualitative interviews these managers' perceptions about the responsibility of gaming corporations to participate in and give back to the local community.
This research also sheds light on Las Vegas, NV, recognized more often for its architecture and cultural zeitgeist than for the contours of its community. A background section on Las Vegas history and its development as a tourist destination provides context for an examination of the ways Las Vegas's nonprofit organizations interact with the city's dominant industry. Nonprofit managers perceive gaming corporations as under- involved in the local community; in addition, they believe the community is under- informed about these efforts, potentially leading to a low level of civic engagement.
This research also examines corporate social responsibility in the context of the economic downturn that began September 2008. Because Las Vegas's economy is so heavily dependent on the gaming and tourism industries, the city provides an excellent location in which to examine how economic forces affect corporate social responsibility efforts. The significant decline in CSR from the gaming corporations, as reported by nonprofit managers. suggests an orientation to CSR that is more functional than moral.

From Plot to Region: Assessing the Role of Land Use in Tropical Montane Forest Structure and Dynamics

de Carvalho Ramos Silva, Lucas

Land Use

Tropical Mountains
Forest disturbance and land use are strong drivers of forest structure, composition, and dynamics and yet, their role in shaping tropical montane landscapes is poorly understood. The overarching goal of my dissertation is to broaden our understanding on the role of land use in shaping forest structure and forest dynamics in tropical montane landscapes, with a particular focus on aboveground biomass (AGB). Using the Northern Mountains of Oaxaca (NMO), Mexico, as a study system, I investigate changes in vegetation across space and time, particularly in an ecosystem known as tropical montane cloud forest (TMCF). The NMO has experience forest disturbance by land use for centuries. Deeply influenced by regional and global socioeconomic forces, land use has changed over time, modifying montane landscapes accordingly. Tropical mountains are currently experiencing large rates of forest loss related to the expansion of agricultural commodity production. Land-use and land-cover change, transformations of land tenure regimes, landscape management strategies, the development of policies related to agricultural production and forest protection, and the environmental conditions that define vegetation growth, are all factors that intertwine to define current and future forest dynamics. Thus, in this project I analyze various aspects of land use in shaping forest structure and dynamics, including the local and regional effects of land-use intensity on tropical montane forests, ways to include these effects at regional scales through forest structure models, and current land use dynamics taking place in the NMO.
In the first chapter I explain the global relevance of tropical mountains and I introduce the foundational concepts of my dissertation, including forest structure and succession, a brief overview of land use in the study region, and the significance of my research. In the second chapter I analyze the relative roles of land use and environmental factors on AGB spatial patterns, as well as the relationship between forest structure and tree diversity. I conclude that land use has a larger role in shaping AGB spatial patterns, and that the relationship between tree diversity and AGB is positive but weak. In chapter three I use remote sensing data to study recent small-scale disturbance related to land use in TMCF. Seeking for novel methods to incorporate land use effects on forest structure in AGB estimates, I found several remote sensing variables that have the potential to be used as input variables in AGB predictive models. These variables are derived from Landsat time series that track vegetation cover change over time. I conclude with providing some recommendations on the use of these variables. In chapter four I assess trends of forest loss and forest conservation in the NMO over the last two decades. Here, I provide a map of the spatial distribution of forest loss and the ecosystems that have been affected the most. I show that forest loss in the NMO has increased in the last six years. I discuss possible driving causes of forest loss, including its relation to the establishment of cattle ranches and agricultural production, and assess the effects of the forest conservation projects taking place in the region. Finally, in the last chapter I summarize the main results of my dissertation.

Interactions Between Tectonism and Magmatism at Santorini: Insights from an Active Source Seismic Experiment
Heath, Benjamin
Hooft, Emilie
Geophysics
Tectonics
Tomography
Volcanology
In extensional volcanic arcs, tectonic and magmatic processes control
the evolution of eruptive centers and their surrounding regions. Faulting, which increases crustal permeability, can focus magmatism and preferentially localize eruptive edifices near intersecting fault zones. In turn, magmatic diking and volcanic edifice growth/collapse can change both the regional and local stress/strain in the crust altering the style and amount of faulting. The relative importance of these magmatic and tectonic processes as well as how these processes coevolve are still poorly known. Here we study magmatic and tectonic interactions at Santorini Volcano, focusing on the localization of magmatism in the highly extended terrain and the subsequent influence of this magmatism on the evolution of tectonic activity. We use the dense PROTEUS active source seismic dataset, collected in
a 120 km x 45 km region around the volcano, to perform both P-wave anisotropic traveltime tomography inversions and full waveform inversions, imaging the upper crust down to ∼4 km depth. Integrating our results with the well-studied volcanic and geologic history of Santorini, we show evidence for strong tectonic control on the evolution of Santorini’s magmatic system. In Chapter II and V, this interaction is recorded as i) the alignment of volcanic features parallel to tectonic features, ii) the localization of volcanism within a tectonic basin, and iii) the strong influence of tectono-magmatic lineaments on both regional volcanic evolution and localization
iv
of caldera collapse. In Chapter III we show that the magnitude of small-scale
local faulting is uncorrelated to regions of magmatic activity indicating that magmatism is neither focused in areas of higher fracturing nor is accommodating substantial extensional strain. Rather both magmatism and small-scale faulting are strongly correlated with regional stress. In Chapter IV we hypothesize that the broad distribution of deformation (>40 km wide) currently observed results from magmatic activity. In contrast, a narrower episode of localized deformation (<20 km wide) preceded initiation of regional magmatism. This highlights the impact of regional magmatism on tectonic evolution. This works shows that magmatic and tectonic processes interact on a variety of temporal and spatial scales.

Platinum(II) Compounds and Nucleolar Stress

Platinum chemotherapeutics
Ribosome biogenesis
Platinum(II) chemotherapeutic agents represent a critical class of anticancer compounds. The clinical use of these compounds is limited by side effects and development of resistance. Despite these limitations, the three FDA approved Pt(II) drugs – cisplatin, carboplatin, and oxaliplatin – remain an important treatment option for many cancers. The molecular mechanisms of these drugs remain unresolved and are the subject of significant investigation. One area of investigation is the impact that Pt(II) compounds have on ribosome biogenesis and the nucleolus. Existing literature has shown that oxaliplatin, but not cisplatin or carboplatin, kill cancer cells via the ribosome biogenesis stress response. This work seeks to clarify the relationship between Pt(II) compounds and ribosome biogenesis stress, alternatively referred to as nucleolar stress. Chapter I provides background on Pt(II) chemotherapeutic agents, the nucleolus, and ribosome biogenesis. Chapter II uses a structure-activity approach to identify unique structural properties that are responsible for nucleolar stress induction as measured by the redistribution of the nucleolar protein nucleophosmin (NPM1) in A549 cells. Chapter III pairs NPM1 redistribution with pulse-chase radiolabeling assays and imaging of other nuclear and nucleolar proteins to establish that reduced transcription of ribosomal RNA transcripts is an early step responsible for nucleolar stress induction by oxaliplatin. Chapter IV summarizes existing methods that allow tracking of Pt(II) compounds in cells, and describes the development of an assay to identify binding sites of Pt(II) on DNA in cells. These analyses allow for a more comprehensive understanding of the relationship between Pt(II) compounds and nucleolar stress.

Whose Voice is it Anyway? The Politics of Narrative Stylistics in Arthur Schnitzler’s Fräulein Else & Han Kang’s The Vegetarian

silence
Spivak
Arthur Schnitzler’s novella Fräulein Else has often been juxtaposed with Freud’s Bruchstücke einer Hysterie-Analyse, and both can be read as an endeavour to ‘give voice’ to the hysteric through representation. This representation, however, depends on someone speaking for someone else, and thus, the ‘hysteric’ herself has no voice of her own. Juxtaposing this with Han Kang’s novel The Vegetarian helps shed light on a different way of communication and understanding, one that does not rely on someone speaking for someone else but allows for the silence of the silenced to be understood on their own term. I draw on Mieke Bal’s narratology and Spivak’s “Can the Subaltern speak?” in order to analyse and describe how representation of the ‘other’ and the possibility of communication with the ‘other’ is presented differently in these three texts and what we can learn from them.

visualization
In situ visualization is increasingly necessary to address I/O limitations on supercomputers. With the increasing heterogeneity of supercomputer design, efficient and cost effective use of resources is extremely difficult for in situ visualization routines. In this work, we present a time and cost analysis of two different classes of common visualization algorithms in order to determine which in situ paradigm (in-line or in-transit) to use at scale, and under what circumstances. We explore a high computation and low communication algorithm, as well as a low computation and medium communication algorithm. We use 255 individual experimental runs to compare these algorithms performance at scale (up to 32,768 cores in-line and 16,384 core in-transit) with a running simulation. Finally, we show that — contrary to community belief — in-transit in situ has the potential to be both faster and more cost efficient than in-line in situ. We term this discovery Visualization Cost Efficiency Factor (VCEF), which is a measure of how much more performant in-transit in situ is on a smaller subset of nodes than in-line in situ is at the full scale of a simulation. Our results for these algorithms showed in-transit VCEF values of up to 8X at our highest concurrencies.

Urban parks play an important role in cities. Lack of understanding about their
effects on urban dwellers and their capacity to play a role in promoting social well-being
could diminish their benefits. With population growth in cities, park managers may need
to increase the quantity and quality or diversify parks to achieve the same results. The
relationship between availability and expenditure on parks and urban quality of life has
received little research attention. An analysis of 75 US cities determined that park
density, operational expenditure and park acreage as a percentage of the city are
significantly related to average levels of income, obesity and violent crimes. Optimum
park density is 49 people per acre of park. Violent crime is a key determinant of whether
urban parks generate a virtuous cycle improving health and income and reducing obesity
rates or a vicious cycle achieving the contrary.

The Geomorphic Effects of Native and Invasive Riparian Vegetation: Sprague River, Oregon
Martinez, Adriana
McDowell, Patricia
Geomorphology

Roughness
Vegetation
Numerous studies have addressed the role of stream geomorphology on vegetation distribution. These studies have shown that channel morphology, including depositional and erosional processes, influence vegetation colonization. However, few studies have addressed the impact of vegetation on the geomorphic processes of streams. Vegetation has the ability to stabilize channel banks and alter stream hydrology and stream power. Little research has addressed the impact of invasive vegetation and its ability to change river channel processes. My research addresses the impact of the highly invasive Phalaris arundinacea and quantifies its influence on the stream channel form of the Sprague River, Oregon. I conducted field research that included root density and root strength surveys to determine the below ground influences of vegetation in terms of added bank cohesion provided by the invasive and two similar native species: Eleocharis palustris and Carex vesicaria. To ascertain differences between the species above ground characteristics and influences, I measured stem density and elasticity to calculate their roughness (Manning's n) and determine their potential impact on stream velocity. Finally, I used these vegetation characteristics to model stream velocity, water depth, and bed shear stress within the 2-D model MD-SWMS. Differences in root size were significant with C. vesicaria having the largest root diameters, largest root area ratio, and largest bank cohesion provided by roots. This was followed by the invasive and then E. palustris. E. palustris had the highest stem density, followed by C. vesicaria and P. arundinacea. The invasive had the highest stem stiffness. E. palustris was associated with the highest roughness value, closely followed by the invasive and C. vesicaria. Using modeling I found the presence of the invasive increased velocity compared to E. palustris and increased bed shear stress compared to C. vesicaria. Therefore, changes in species composition, such as a shift from either of the natives to the invasive, could affect channel morphology over time. By comparing the impact of this invasive to that of native grasses and sedges, this research provides insight into how further spread of the invasive may affect the Sprague River and other riparian ecotones.

Organics at aerosol interfaces greatly affect aerosol properties in turn affecting the climate. However, many aspects about the formation and atmospheric processing of aerosols, in particular secondary organic aerosol (SOA), remain poorly understood. The traditional mechanism of SOA formation does not adequately predict experimental observations in the atmosphere. It is increasingly being recognized that aqueous phase processing of atmospheric organics is another important pathway to SOA formation. A better picture of the surface behavior of these organics and their reaction products will aid in further understanding the role these organics play in the formation potential of aqueous secondary organic aerosol. The work within details studies on the adsorption, orientation, and hydration state of select atmospheric carbonyls (glyoxal, hydroxyacetone, methylglyoxal, and pyruvic acid) and their aqueous reaction products at the air-water interface. Data are gathered using a combination of experimental and theoretical techniques, including vibrational sum frequency (VSF) spectroscopy, surface tensiometry measurements, classical molecular dynamics (MD) simulations, and density functional theory (DFT) calculations.

Before the World: Kaga No Chiyo & the Rustic-feminine Margins of Japanese Haiku
Crowson, Michelle
Walley, Glynne
This dissertation tracks the transformation of the merchant-class female poet, Kaga no Chiyo, from a minor supplementary position as a collected feminine object to an interlocutor and exemplar of post-Bashō poetics in regional circulation. I argue that discourses on the fall of haikai poetry among eighteenth-century male practitioners, combined with the rise of an eccentric bunjin “literati”) consciousness, led to a pattern of rural male poets collecting women as casual supplements to masculine-coded poetic communities, part of a larger valorization of a poetics of simplicity and lightness. Chiyo’s early encounters with male collectors delimited the value of her work to an unrevised, spontaneous simplicity, a simplicity she was actively discouraged from honing. Yet Chiyo acted against this advice, instead drawing on three forms of poetic sociality (travel, correspondence, and preface-writing) to enact a nested bunjin subjectification, ultimately subverting both state and subcultural discourses through a nuanced poetics of eccentric marginality. By 1774, she had cultivated a female bunjin identity that transcended well beyond her initially prescribed role, becoming one of the genre’s most notable figures in two key related capacities: first, she became a widely acknowledged representative of women poets of the Bashō legacy, acting as interlocutor for both sides of the mid-century Bashō Revival movement. Second, she authored a collection of poetic art objects that circulated beyond the borders of Tokugawa Japan to the Korean Peninsula in 1764, which was subsequently read by domestic readers as further evidence of her significance as a haikai figure. Furthermore, when viewed within a larger East Asian literati context, I argue that Chiyo’s Joseon collection can be read as the manifestation of a local aesthetic with regional complementarity, a phenomenon which foreshadows haiku as national-linguistic representative of Japan in world literature.

Prospect Theory-Based Explanation of Majority Nationalist Mobilization: Cases of Russia and Kazakhstan

Bottom-up nationalism
Cognitive approach
Kazakhstan
Majority nationalism
Prospect theory
Russia
The current dissertation has a dual purpose of developing a theory of majority nationalistmobilization and explaining substantive variation in levels of nationalist mobilization in post-
Soviet region during the first two decades after the collapse of the Soviet Union, particularly in
the country cases of Russia and Kazakhstan. The study begins by pointing out at the failure of
major theoretical approaches to nationalism such as modernism and perennialism to account for
a phenomenon of bottom-up majority nationalist mobilization, a variation in levels of which can
be observed in these two countries through the period of 1990s-2000s. It then develops a theory
of bottom-up majority nationalist mobilization based on the combination of insights from the
cognitive perspective to ethnicity and prospect theory. Further, using qualitative cross-case and
within-case analysis, the dissertation tests suggested theory against empirical evidence in cases
of Russia and Kazakhstan and demonstrates that this framework provides better explanation to
divergent mobilization outcomes in these countries then existing rational-instrumentalist and
non-rationalist theoretical alternatives.

Transition services for youth with disabilities are mandated by IDEA. Transition services are supported services that help individuals with disabilities move from special education in high school to employment, post-secondary education or vocational training in the adult world. Outcomes for youth with disabilities vary depending on culture, ethnicity, race, gender and socioeconomic status. Latino youth with disabilities experience poorer post-school outcomes than do white youth with disabilities. This study seeks to identify and describe the transition needs of youth with disabilities from Latino backgrounds who are transitioning from school to adulthood and therefore engaging in employment, post-secondary education or employment-related training. Through focus groups with Latino youth, their families, and the staff that serve them, I explored and identified the specific needs of this group with regards to receiving transition services. The findings of this study will guide the development of training for transition professionals in Oregon and will be disseminated to professionals in the field of transition across the country and around the world.

Deformation across plate boundaries often occurs over broad zones with relative motions between plates typically accommodated by faults of different styles acting together in a complex system. Collision of the Yakutat microplate within the Alaskan portion of the Pacific-North America plate boundary drives deformation over 600 km away where the Denali fault divides predominantly rigid crustal block motions of southern Alaska from distributed deformation in central Alaska. Quaternary geologic mapping along the Nenana River valley and the Japan Hills of the northern foothills of the Alaska Range defines zones of Quaternary thrust faulting recorded in the progressive deformation of Pleistocene fluvial terraces. I use topographic profiles of these terraces and paleoseismic trenching of fault scarps to characterize the Quaternary activity and constrain the subsurface geometry of these faults. Radiocarbon and cosmogenic exposure dating methods provide age control on the stratigraphy in the trenches and landforms offset by these faults. These observations define a 1-1.5 mm/yr slip rate for the Gold King fault which changes laterally from a north-vergent thrust into a north and south vergent thrust wedge that uplifts the Japan Hills. Along the Nenana River valley, the progressive deformation of Pleistocene surfaces defines a north-vergent critically-tapered thrust wedge. The geometry of progressive uplift and folding requires a near planar, south-dipping basal thrust fault with two major north-dipping backthrusts. All three faults were active simultaneously on a scale of 10 4 yrs with slip rates of 0.25-1 mm/yr, until the late Pleistocene when we infer the retreat of glacial ice from the main axis of the Alaska Range caused a change in thrust wedge dynamics. I use the orientation of Quaternary deformation north of the Denali fault to show that strain is highly partitioned and establish geologic constraints on the regional horizontal stress orientation. North of the Denali fault, fault-normal principal shortening accommodates 3-5 mm/yr of strain transfer across the Denali fault system. Two appendices contain additional results of paleoseismic trenching and neotectonic investigations across 4 active faults near the Nenana River.

Vapor Retarder
This thesis attempts to determine if misconception about vapor retarders and air barrier systems affects building enclosure design and construction. Literature on this subject is continually evolving and often contradictory, supporting confusion. A survey of designers and builders representing four climate zones within the United States was done. Respondents disclosed where they learned about building enclosures and shared how clear or confusing they think the resources are on this subject and also weighed in on a few basic principles about enclosure design. Results show that most building professionals learn about enclosures through experience or a colleague. The internet is the first written resource they use when questions arise. The most significant misconceptions identified are that in some cases vapor retarder placement does not follow accepted building science or code requirements and that a portion of respondents only consider the air barrier system the vertical surfaces of an enclosure.

People’s psychological well-being is essential to study since past studies have indicated that negative mood can lead to many other significant health problems. Virtual
reality and music therapy have both been used in the past for therapy but there is still
limited research when using them together. This study examined the effectiveness of VR
vs. 2D online interventions with various stimuli (audiovisual vs. visual only vs. audio
only) to assess which interventions were effective. Additionally, this study examined
which groups displayed the highest amount of presence to understand what elements are
essential when increasing attention. The results suggest that even though VR participants
generally experienced more presence and had similar benefits for positive mood, 2D
groups were the only groups effective for reducing negative mood. These results suggest
that there could be other psychological and theoretical considerations that may play a role
into determining what online experiences are effective.

The Influence of Deep-Seated Landslides on Topographic Variability and Salmon Habitat in the Oregon Coast Range, USA
Beeson, Helen
Fonstad, Mark
Deep-seated landslides
Oregon Coast Range
Salmon
A well-accepted idea in geomorphology is that landforms control the type and distribution of biological habitat. However, the linkages between geomorphology and ecology remain poorly understood. In rivers, the geomorphic template controls the hydraulic environment, partly shaping the river ecosystem. But what processes shape the geomorphic template? Here, I examine how two hillslope processes dominant in the Oregon Coast Range, debris flows and deep-seated landslides, affect valley floor width and channel slope, key components of the geomorphic template in riverine ecosystems. I then investigate how patterns in potential salmon habitat differ between streams dominated by deep-seated landslides and streams dominated by debris flows. I show that terrain influenced by deep-seated landslides exhibits (1) valley widths that are more variable throughout the network but less locally variable, (2) more variable channel slopes, and (3) more potential salmon habitat as well as significantly more connectivity between habitat types.

Detecting and Modifying Chromatin Organization in the Budding Yeast Genome with Synthetic Proteins
Banks, Orion

Nucleosome positioning
Synthetic biology
DNA in the nucleus of eukaryotic cells is condensed into chromatin by forming specialized structures called nucleosomes. DNA is wrapped around a set of histone proteins to from nucleosomes, which are eventually positioned by robust, reproducible mechanisms. Mutations in chromatin organizing proteins are common in human diseases, indicating that studying the systems in place to control chromatin organization could be insightful for developing novel therapeutics. S. cerevisiae is an ideal model organism for this work, as it is tolerant to dysregulated nucleosome positioning, genetically tractable, and contains homologs of many human proteins. Here, I describe several studies that have furthered our understanding of chromatin organization in the context of nucleosome positioning. First, I detail a set of synthetic proteins that enable nucleosomes to be repositioned at characteristic sites in the yeast genome. Following this is a detailed account of our investigation into the biochemical mechanisms underlying targeted chromatin remodeling at a subset of genome loci by the chromatin remodeler Isw2. Next, a protocol for efficiently detecting nucleosome positions is described, including its application to yeast deficient in chromatin remodeling activity. In chapter five, I present a system for detecting protein-DNA interactions and nucleosome positions using targeted nuclease digestion with endogenously expressed proteins. I also outline some of the potential applications of this technique, including use with chromatin remodeling proteins, which often prove difficult to map with standard methods.This dissertation contains previously published co-authored material.

Effect of FFI Models on Chinese L2 Accuracy
Chen, Jing-Yun
Jing-Schmidt, Zhou
Chinese adverbial phrases
Explicit instruction
FFI
Implicit instruction
Previous studies of form-focused instruction (FFI) have examined the effect of various aspects of inputs, corrective feedbacks, and instructions on L2 learners' accuracy development. Although much research has suggested that L2 learners achieve high accuracy and communicative competence when they receive input enhancement, explicit instruction, and corrective feedback, limited work has been done on the effect of FFI in Chinese language. The thesis utilized qualitative and quantitative methods and tested the effect of two FFI models on two groups of learners' acquisition in Chinese adverbial phrases. Even though the quantitative results show that the group that received explicit treatment had significantly improved accuracy in the immediate and delayed post-tests, the interview results revealed that students have different learning styles. This further suggests that no one right instruction is the best, and teachers should implement various teaching approaches based on students' needs.

Modeling Circulation Dynamics and Submarine Melt in Greenland Fjords
Carroll, Dustin
Sutherland, David
Glacier
Greenland
Ocean-ice
Physical oceanography
Submarine melting
Meltwater accumulated on the Greenland Ice Sheet drains to glacier beds, discharging into fjords hundreds of meters below sea level. The injection of meltwater at depth generates an upwelling plume that entrains warm ocean water as it rises along the terminus, increasing submarine melt and driving a fjord-scale exchange flow. However, due to sparse ocean-glacier observations, we lack a process understanding of how plumes control fjord circulation and submarine melt. Combining numerical modeling, theory, and observations, this dissertation investigates near-glacier plume dynamics, the influence of glacier depth on plume structure and submarine melt, and the role of fjord-glacier geometry on circulation in tidewater glacier fjords.
In Chapter II, I use buoyant plume theory and a nonhydrostatic, three-dimensional ocean–ice model to investigate the sensitivity of plume dynamics to subglacial discharge, turbulent diffusivity, and conduit geometry. Large discharges result in plumes with positive temperature and salinity anomalies in the upper water column. Fjord circulation is sensitive to conduit geometry; distributed subglacial discharge results in a stronger return flow of warm water toward the terminus. In Chapter III, I use buoyant plume theory, initialized with realistic ranges of subglacial discharge, glacier depth, and ocean stratification, to investigate how plume structure and submarine melt vary during summer months in 12 Greenland fjords. Grounding line depth is a primary control on plume-induced submarine melt: deep glaciers produce warm, salty subsurface plumes that undercut termini, and shallow glaciers produce cold, fresh surface-confined plumes that can overcut. Finally, in Chapter IV, I use regional-scale numerical ocean simulations to systematically evaluate how fjord circulation forced by subglacial plumes, tides, and wind stress depends on fjord width, glacier depth, and sill height. Glaciers grounded below sill depth can draw shelf waters over a shallow sill and into
fjord basins with seasonal subglacial discharge; this process is independent of external shelf forcing. These results underscore the first-order effect that subglacial discharge and fjord-glacier geometry have in controlling fjord circulation and, thus, ocean heat flux to the ice.

Thinking about Justice from “the Outside” of Nationality: Re-Thinking the Legal and National Dimensions of Citizenship

xi, 202 p.
This dissertation examines the legal and national dimensions of citizenship, focusing on the nature of social justice, multiculturalism and state formation in light of an increasing "migrant" population in the United States.
For many individuals, Hispanic people and undocumented immigrants are outside of stereotypic understandings of "American" and the legal structure of the United States. Seeking to question this belief and the subsequent political atmosphere it engenders, this work presents the challenges that Hispanic people and undocumented persons pose to the central tenants of liberal political theory and the politics of recognition.
Liberal theories of justice that assume the nation-state as their starting point and ignore the international elements of 21st century societies need reconsideration. Although John Rawls's work remains central to this tradition, by constricting his theory of justice to a closed, self-sustaining polity that assumes all persons behind the veil of ignorance to be citizens, the trajectory of liberal political thought after his work evades the question of citizenship and the possibility of social justice for undocumented people. Although conversations about "multicultural citizenship" are abundant in North American political contexts, these discussions focus on the national representation of minority peoples and ignore the legal aspects of citizenship and the reality of undocumented immigration. Philosophers that do think about undocumented persons argue for international theories of justice, human rights or cosmopolitanism. These are positive steps in thinking about social justice for immigrants, but they only matter insofar as they do not impinge upon state sovereignty and render social justice for immigrants a secondary issue.
While Latin American political thinkers such as Enrique Dussel ground the origins of political power in the citizenry of states, they nonetheless assume the category of "citizen" to be uncontested. Thus, even in settings where radical political change is underway, the basis of state membership remains to be defined and freed of racial (or even "post-racial") expectations. I undertake this project in terms of Estadounidense or "Unitedstatesian" citizenship, a concept that combats ethnocentric beliefs about the meaning of "American" while also informing of more open understandings of legal citizenship and porous conceptions of the state.

Expressing Disempowering Realities Through the Body: An Embodiment Approach to Disordered Eating in Black and African American Women

Disordered eating (DE) among Black women in the United States (U.S.) has increased over the past decade. Although theories of DE have predominantly focused on the drive for thinness, these frameworks fail to demonstrate the same predictive validity among Black women. Embodiment, which reflects the experience of living in one’s body, offers a novel framework for examining DE among Black women by considering the roles of disempowering social experiences (e.g., discrimination) in shaping how one connects to and cares for their body. The current study examined the associations among food insecurity, exposure to traumatic events, discrimination distress, embodiment, and DE (i.e., global symptoms, binge eating, and unhealthy weight control practices). It was hypothesized that food insecurity, traumatic events, and discrimination distress would be collectively significantly associated with both embodiment and DE. It was also hypothesized that embodiment would be significantly negatively associated with DE after adjusting for food insecurity, traumatic events, and discrimination distress. Black women 18 to 40 years old in the U.S. (N = 99; Mage= 27.77 5.17 years) completed an online survey comprising measures of food insecurity, traumatic events, discrimination distress, embodiment, and DE.
Multiple regression models revealed that food insecurity, traumatic events, and discrimination distress were collectively significantly associated with embodiment (p < .001) and global DE (p < .001). Zero-inflated negative binomial models demonstrated improved model fit compared to the intercept-only models for binge eating (BF = 1.63) and unhealthy weight control practices (BF = 146 x 104). Considering individual variable contributions, exposure to traumatic events was significantly positively associated with global DE and likelihood of binge eating; food insecurity was significantly negatively associated with global DE; and discrimination distress was not significantly related to any DE constructs (ps = .137-.620). After adjusting for food insecurity, traumatic events, and discrimination distress, embodiment was significantly negatively associated with global DE (p < .001), the likelihood of binge eating (p =.01), and unhealthy weight control practices (p =.03).
Results suggest that disempowering social experiences are relevant to Black women’s DE, and embodiment may provide a valuable theoretical perspective for understanding DE in Black women.

Linking Forms, Singularities, and Homological Stability for Diffeomorphism Groups of Odd Dimensional Manifolds

Let n > 1. We prove a homological stability theorem for the
diffeomorphism groups of (4n+1)-dimensional manifolds, with respect
to forming the connected sum with (2n-1)-connected,
(4n+1)-dimensional manifolds that are stably parallelizable.
Our techniques involve the study of the action of the diffeomorphism group of a manifold M on the linking form associated to the homology groups of M.
In order to study this action we construct a geometric model for the linking form using the intersections of embedded and immersed Z/k-manifolds.
In addition to our main homological stability theorem, we prove several results regarding disjunction for embeddings and immersions of Z/k-manifolds that could be of independent interest.

Politeness and Multimodality in Korean and Japanese

This dissertation work aims to explore multimodal strategies of politeness in Korean and Japanese by investigating 7 hours of spoken and visual data produced by Korean and Japanese speakers. The analysis particularly deals with ways of controlling density of lexical information, use of kinetic cues and manipulation of gestural space in deferential and non-deferential situations. To begin, the first study examines how speech in interactions with a status-superior and a status-equal differ in the quantity of honorific lexemes, honorific sentence-ending particles, formal case-marking particles, mimetics, Chinese-origin words, pronouns, fillers and backchannels. Statistical tests revealed that use of honorifics and other lexical items that are related to formality and politeness increase in deferential situations. On the other hands, the general quantity of lexical information given to the addressee did not significantly differ in deferential and non-deferential situations. Second, in the study on kinetic cues of politeness, it was found that deference and intimacy can be embedded by manipulating multiple types of nonverbal behavior involving manual gesture, head movements (nodding and shaking), erect body posture, eye contact and self-touch by looking at the frequency in formal and informal situations. In general, both native speakers of Korean and Japanese more actively and animatedly moved their bodies in intimate situations compared to deferential situations. An additional analysis further revealed that Korean and Japanese speakers use smaller gestural space to produce manual gestures when interacting with a superior than when interacting with a friend. In conclusion, this study contributes to developing methodological approaches of research on politeness by demonstrating that politeness-related verbal and nonverbal behaviors can be quantitatively examined. Furthermore, the statistical results indicating particular verbal and nonverbal patterns of (im)politeness support the perspective that politeness is a social practice of members of a community that share similar moral orders. Lastly, the findings that show how (im)politeness is complicatedly expressed in verbal and nonverbal ways can also have significant educational implications in that this research has brought to the forefront the issues in classes of Korean and Japanese where the focus of (im)politeness instruction has been placed mainly on honorifics rather than the true multimodality of (im)politeness.

Time-Dependent Approaches and Their Utility: Dynamical Formulations of Two-Dimensional Electronic Spectroscopy Signals and Electronic Structure Theory
Kiessling, Alexis
Cina, Jeffrey
Electronic Structure Theory
Fourier transform
Ultrafast Spectroscopy
Wave-packet dynamics
Wave-packet Interferometry
We present time-dependent reframings of the theory of two-dimensional electronic spectroscopy signals and of electronic structure theory. The dynamical formulation of spectroscopic signals, in particular of two-dimensional wave-packet interferometry (WPI), is used to calculate and interpret signals from a spatially oriented energy transfer dimer. A general study of the detection of electronic energy transfer using WPI is carried out. The signals are interpreted using a semiclassical analysis that considers the paths taken by wave packets through phase space and the conditions required for their phase-space overlap. The dimer is also used to propose a WPI experiment capable of observing electronic intersite and interexciton coherence. Weak-coupling (intersite) and strong-coupling (interexciton) cases are studied, with a variety of systems differing in number of vibrational modes and in excited-state energies of the monomers. The time-dependent framing of electronic structure theory is a spectral filtering technique, where the Fourier transform of the time evolution of an antisymmetrized wave packet to the frequency domain reveals eigenstates and eigenenergies. Direct numerical integration of the time-dependent Schrödinger equation and semiclassical parametrizations are presented and compared as methods of obtaining the time evolution. The method is found to be accurate, and has some benefits; spectral filtering allows for many
eigenstates to be obtained at once and includes electron correlation automatically. Future prospects for each of these works are discussed.

This qualitative and experiential research focuses on the nexus of language with
educational and artistic goals within dance communities. The study shares descriptive
language identified during my Master of Fine Arts Movement Project community's
collaborative processes, as we explored "skill training" and "art making" in dance over a
period of 10 weeks. Recommendations emerge through discussion of current dance
dialogic models and collaborative language resources for dance. Reviewed resources
outside the dance field provide additional support and context. Based on the
community's shared experiences and the researcher's investigations, suggestions are
made for increasing quality of practice in dance and language articulation. Practical
applications are offered.

Communal Agency in Josiah Royce
Jacobs, Matthew
Pratt, Scott
Collective agency
Community
Pragmatism
Royce
On the common sense view, an agent is an individual. Communities are collections of individuals, but the community itself is not understood to possess a collective, unified agency. Nevertheless, this view stands at odds with frequent ascriptions of communal agency; e.g., "Oregonians are environmentally conscious," "The team played to win," "The LGBTQ community is pro-gay marriage." If we are to vindicate such ascriptions, we need a theory of the "reality of community," the thesis that under certain conditions, a community possesses a unified, collective agency. This work reconstructs Royce's theory of communal agency through his views of purposiveness and the use he makes of C.S. Peirce's "theory of interpretation." I argue that, for Royce, agency is purposiveness and purposiveness always bears the triadic structure of the process of interpretation. Thus, the process of interpretation entails agency whether at the level of the individual or at the level of the community.

Ceratostoma ioornatum is an introduced marine snail in Puget Sound,
Washington. Two of five native species tested as possible predators ate
Ceratostoma. These two species, the crabs Cancer gracilis and
Lopbppaoopeys bellys, did not eat native snails similar to Ceratpstpma,
but ate native and introduced bivalves more than Ceratpstpma. The
reasons for the differences in predation seemed to be explained by shell
strength of the prey species. The presence of Ceratpstpma adds a new
type of prey to the menu of the two crab species
at the sites studied.

This dissertation research examines the work arrangements of software workers in high-technology industries in order to raise questions, dispel myths, and develop a labor process theory of knowledge-based work in the 21st century. Software work is largely regarded as a “sunrise” occupation: full of opportunities for interesting work in a flexible environment. Moreover, software production, like other forms of knowledge-based work, is presumed to pose challenges to managerial control methodologies, because of employers’ increasing dependence on software workers’ skills and creativity and the difficulty of subjecting complex, immaterial, and cognitive work like software production to traditional methods of control. As a result, knowledge-based work appears to require new forms of control, distinct from those used in manufacturing settings. This research, however, reveals continuities between managerial methodologies used in manufacturing-based settings and those used to organize software work through an analysis of Agile, a popular project management methodology. Agile’s roots are in Toyota’s lean production processes, though Agile also draws upon tenets of Taylor’s scientific management as well as High-Commitment Management schemes. Drawing upon 45 interviews with workers and managers who use Agile, as well as content analysis of Agile training videos, I show how Agile aims to achieve what I call Taylored Flexibility: an attempt to maintain flexibility to respond to the complex and turbulent nature of knowledge-based work alongside strategies to render invisible and immaterial work like software production more calculable and predictable. This dissertation also explores collective organizing strategies of software workers, emphasizing how struggles over control may not take the traditional form of conflict over pay, benefits, or the conditions of work, but of the outcomes of labor. Through this research I show that managerial strategies used to achieve Taylored Flexibility complicate common understandings about control over knowledge-based work in the new economy, showing how hybrid control regimes can operate as powerful mechanisms to render knowledge-based work more productive.

How Can Low-Carbon Energy Dematerialize the Economy? Technological Transitions and the Political Economy of Electricity Generation
Sikirica, Amanda
York, Richard
displacement paradox
energy transition
Pacific Northwest
world-systems
This dissertation addresses features of the displacement paradox in the context of electricity generation, both at the cross-national level and within one region of the United States. The displacement paradox is the empirical phenomenon of substitutes to a specific product, here fuels used to generate electricity, do not necessarily replace incumbent products in a 1:1 ratio thus increasing total resource consumption, and in some examples are observed to increase consumption of the incumbent product. Chapter 1 describes how the displacement of fossil fuels with non-fossil fuels varies based on a nation’s social structural position within the global capitalist world-system. I find that semiperiphery nations have higher predicted displacement of fossil fuels, possibly due to the dynamics of domestic elites. Chapter 2 asks how multiple dimensions of domestic inequality (gender inequality, economic inequality, and colonial history) may create landscapes of inequality on which nations are or will attempt to move away from fossil fuels. I find that much of the variation in national-level displacement of fossil fuels with alternatives can be attributed to the additive effects of each dimension of inequality, though there is some portion of variation which can be attributed to multiplicative effects. Chapter 3 traces the development of hydroelectricity in the U.S. Pacific Northwest, and subsequent growth of the region’s consumption of fossil fuels. This history illustrates an example of the displacement paradox, whereby the growth of an alternative fuel (hydroelectricity) contributed to the growth of fossil fuels in the region. This chapter points out the role of institutional continuance, grid management, and neoliberalization of the electricity industry in the growing reliance of the region on fossil fuels. In total, this dissertation demonstrates the roots of the displacement paradox in social organization and the distribution of social power as mediated by capitalist production.

How to Apply the Schenkerian Method to the Performance and Teaching of Chopin's and Mozart's Piano Music
Wang, Yanjie
Boss, Jack

Performance
Piano pedagogy
Schenkerian method
This thesis focuses on the relationship between piano performance and Schenkerian analysis. Schenkerian analysis was designed initially as a practical guide for performers. In the different levels of a Schenkerian graph, we can see “musical forces” which lead the performer to deeply understand music itself. Using Schenkerian notation to highlight certain notes helps us to recognize lines behind the surface of the music that give certain passages coherence. This study concentrates on Chopin’s mastery of counterpoint and voice leading which leads me into the relationship of analysis and performance, typically by using the Schenkerian method. My examples will include a variety of pieces by both Chopin and Mozart, to show in what ways the Schenkerian analysis both highlights similarities and makes distinctions between composers and genres.

Greater Access to Recreational Resources is Associated with More Leisure-time Physical Activity Engagement in Counties Across the United States
Pedroza, Jonathan
Budd, Elizabeth
access to recreational resources
leisure-time physical activity
spatial regression
Less than 10% of U.S. adults meet physical activity recommendations. Physical inactivity leads to poor physical and mental health conditions. Little is known about community factors on a county level associated with leisure-time physical activity (LTPA), despite LTPA demonstrating greater health benefits than other physical activity domains and most local health departments operating on county levels. This study: 1) examines the association between access to recreational resources and LTPA, and 2) investigates violent crime rates as a moderator of this association across U.S. counties. Data on access to recreational resources (e.g., parks, gyms), LTPA, violent crime rates, median household income, and percent rurality, Black/African American population, and Latina/o population were analyzed from 2016 County Health Rankings and Roadmaps and American Community Survey. With U.S. counties (N = 3089) as the level of measurement, three spatial regression models stratified by region (Northeast, South, West, Midwest) were conducted. Access to recreational resources was positively associated with LTPA in the Northeast (b = 0.058, p = .001), South (b = 0.025, p < .001), and West (b = 0.046, p < .001). Violent crime rates moderated the association between access to recreational resources and LTPA in the Northeast only (b = 0.002, p = .032), showing a significant positive association (b = 0.108, p < .001) only among counties with higher violent crime rates. Exploratory findings indicated median household income moderated the association between access to recreational resources and LTPA in the West (b = 0.002, p = .003) and Midwest (b = 0.001, p = .040). County median household income may matter more as a moderator than violent crime rates in the positive association between access to recreational resources and LTPA, particularly in the West and Midwest. These findings can inform future LTPA promotion interventions by concentrating efforts on improving access to recreational resources and addressing inequities in access based on median household income.

Introduction: Education is a social determinant of health, and its intersection with incarceration is a powerful nexus for well-being of students. Whether policies specific to student well-being are associated with exclusionary discipline, a documented risk factor for incarceration, is unknown. This study has three aims: (1) to identify whether there is an association between local school wellness policies’ (LWPs) quality and exclusionary discipline incidents (EDIs) in Oregon high schools; (2) if the quality of specific policy domains (i.e., nutrition education and physical activity) is associated with EDIs; and (3) to determine if total LWP quality moderates the association between out of school suspensions and days missed due to suspension. Methods: Data for Oregon high schools’ LWPs were collected in 2017 and cross-matched to public, school-level student demographic data from the Oregon Department of Education in 2017 and enrollment and suspension data from the Office of Civil Rights Data Collection were collected for 2017-2018 year. Including post hoc analyses, ten multiple regression models were created to examine variation in EDIs. All models were adjusted for relevant covariates.
Results: Total LWP quality was not significantly associated with EDIs, nor was the quality of either Nutrition Education or Physical Education/Physical activity LWP domains. Post-hoc exploratory analyses revealed the strength of Standards for USDA Nutrition Programs and School Meals domain was negatively associated with EDIs (Cohen’s f2 = 0.05) as was comprehensiveness of the Wellness Promotion and Marketing domain (Cohen’s f2 = 0.15). The strength of Wellness Promotion and Marketing was positively associated with EDIs (Cohen’s f2 = 0.06). Total LWP quality was not associated with days missed due to suspension, and there was no moderating interaction detected.
Conclusion: The quality of two specific LWP domains, rather than total LWP quality, may matter in regard to EDIs in Oregon high schools. Results could aid informed policy decision making for promoting health equity on district and state levels. Future research should identify if these associations are present in other states.

Demystifying Racial Monopoly
Haller, Reese
Russell, Camisha
Anti-Racism

Monopoly Capitalism
Race
Rainbow Coalition
Social Construction
Through analysis of private, public, and state reactions to the Great Depression and northward black migration, this thesis demystifies four key functions of race constitutive of capitalist racial monopoly: historical availability, division of labor, motivation of surplus absorption, and embodiment of false consciousness. Nonetheless, the working class’s immanent limitations and transcendent activities in this paradigm later gave rise to the 1950s and 60s racial liberation movement’s social constructionist critiques. The following counterintelligence reactions of the Federal Bureau of Investigation neutralized, abstracted, and mystified such racial politics, rendering their truncated identarian form available to a variety of political groups from the anti-racist left to the ethnonationalist right. In this way, capital now appropriates resistant racial politics as part of a commodified and mutually antagonistic multiracial plurality. To resuscitate multiracial coalitional politics that can challenge capital’s racial monopoly, today’s anti-racism must reassess the historical development of racial monopoly in the mid-twentieth century.

Mediations from Under the Cloak: Christianity, Trauma, and Reconciliation in Brennu-Njáls Saga
Young, Jeremiah
Gurley, Gantt

Sagas
Trauma
This thesis explores the representation and testimony of trauma in the medieval Brennu-Njáls saga. Beginning with an outline of contemporary trauma studies, this thesis examines the repercussions narratives of social trauma. The chapters 100-105, the burning of Njal and Flosi’s dream show the repercussions of the conversion as affecting not only the characters in the saga, but also landscapes, supernatural events and even the text itself. Njál’s saga proves to be a exemplar of medieval trauma narrative as it displays the trauma of the characters in the tenth century, and provides a metatextual testimony of saga compiler’s own trauma stemming from the loss of the Icelandic common wealth in the thirteenth century. Njál’s saga exposes the violence of the tenth century and shows that even in the twenty-first century the reader must deal with the traumas long past.

xv, 372 p.
In my dissertation I argue that because the European Union and the United States of America have been largely treated as unique or at least special cases, both the literature on American-state building and that on European market integration have missed how close comparison alters both our descriptive views and social-scientific explanations of the shape of each polity. In particular, scholars have not sufficiently recognized that the European Union has gone further than the United States in many elements of the creation of a centralized, liberalized single market, nor have they produced explanations that account well for this development.
This study challenges the dominant assumption that the United States is generally more hierarchical and centralized than the European Union and more of a single free market in the sense of fewer allowable trade barriers. By analyzing the rules of market integration in services (over 70% of GDP), public procurement (15 - 20% GDP) and the regulated goods markets (goods like elevators with their own regulatory regimes), I demonstrate that in all these major cases the European Union has adopted rules that open exchange to competition more than the United States. While the actual integration of flows on the ground is still generally less across European states than American ones, the political rules are more - and more liberally - integrated in Europe.
I offer an institutional and ideational argument to explain these differences, with two main parts. First, there is no American parallel to the institution of the European Commission, which is mandated to continually push liberalization forward. My research shows that Commission leadership has been critical to each of the examined cases. Second, broader norms of legitimate governance favor centralized authority - including liberalizing central authority - more in the European Union than in the United States. Despite all the criticism we hear of the European Union, the basic notion of federal governance of market integration is far more strongly accepted across Europe at both elite and mass levels than in the United States. As interview evidence in this study displays, many Americans consistently object to any role for the federal government.

xxv, 492 p. : music
This study applies Schenkerian theory to Chet Baker's jazz improvisations in order to uncover the melodic, harmonic, and contrapuntal hallmarks of his style. Analyses of short excerpts taken from multiple recorded improvisations reveal Baker's improvisational vocabulary, which includes recurring underlying structures that Baker embellishes in a wide variety of ways and places in a wide variety of harmonic contexts. These analyses also explore other traits (rhythmic, timbral, etc.) that appear in Baker's improvisations throughout his career. The dissertation culminates in three illustrative analyses that demonstrate the ways in which Baker constructs single, unified improvisations by masterfully controlling the long-range voice-leading tendencies of his improvised lines. As he weaves his vocabulary into these lines, he creates improvisations that unfold in a way that is logical, satisfying in the fulfillment of expectations, and motivically cohesive on multiple levels of structure.

A Structure Theorem for RO(C2)-graded Cohomology
May, Clover
Dugger, Daniel
Let C2 be the cyclic group of order two. We present a structure theorem for the RO(C2)-graded Bredon cohomology of C2-spaces using coefficients in the constant Mackey functor F2. We show that, as a module over the cohomology of the point, the RO(C2)-graded cohomology of a finite C2-CW complex decomposes as a direct sum of two basic pieces: shifted copies of the cohomology of a point and shifted copies of the cohomologies of spheres with the antipodal action. The shifts are by elements of RO(C2) corresponding to actual (i.e. non-virtual) C2-representations.

Inspiration for this piece is drawn from two sources: the novel <italic>Slaughterhouse Five</italic> by Kurt Vonnegut Jr., and my desire to utilize techniques derived from various musical cultures, including Balinese gamelan and African drumming and marimba playing. Although not directly narrative, much of the imagery portrayed in <italic>Slaughterhouse Five</italic> informed the emotional landscape of the piece. As to the use of techniques from other cultures, my aim is not to merely imitate them, but to utilize them in a manner appropriate to the tradition of orchestral concert music.

Thin Film van der Waals Heterostructures containing MoSe2 from Modulated Elemental Precursors
Hadland, Erik
Boettcher, Shannon
Materials
Solid state
Transition metal dichalcogenides (TMDs) are naturally occurring layered materials that have attracted immense research interest due to their high degree of chemical tunability. In particular, MoSe2 has been the focus of significant investigation stemming from reports that it converts to a direct band gap semiconductor material at ultralow dimensions. Yet, as more and more is learned about increasingly thin MoSe2, efforts are now aimed at imparting the novel functionality of MoSe2 into van der Waals heterostructures. This dissertation focuses on synthesis and characterization of novel MoSe2-based nanolaminate structures that have been self assembled from modulated elemental precursors.
The first section describes a new treatment of x-ray fluorescence spectroscopy data and its use as a powerful probe for determining the absolute composition per unit area of a thin film with sub-monolayer accuracy. While this has widespread application in the thin film world, it is particularly useful for MER synthesis in the calibration of modulated elemental precursors. In order to crystallize a target structure, it is imperative to deposit the correct number of atoms, which is now possible with greater precision.
The second section shows the importance of rotational (i.e. “turbostratic”) disorder on lowering cross-plane thermal conductivity in two systems—MoSe2 and the (SnSe2)1(MoSe2)1.32 heterostructure. The binary systems exhibits ultralow thermal conductivity that rivals that of WSe2, yet some interlayer atomic registry was noted in TEM images. By interleaving layers of MoSe2 with SnSe2—which also possesses hexagonal symmetry, but has a significantly larger basal plane—the cross-plane thermal
iv
conductivity was depressed to the lowest reported value in the literature for a fully dense solid.
The final section presents the synthesis and characterization of a new, ternary phase of Bi|Mo|Se. The structure consists of alternating layers of a “puckered” rock salt BiSe lattice and nanosheets of MoSe2. Notably, the MoSe2 sublattice consists of a mixture of the semiconducting 2H phase (~60%) and the metallic 1T phase (~40%). This is the result of electron injection from the BiSe into the conduction band of the MoSe2, which is known to undergo a rearrangement upon reduction.
This dissertation includes previously published and unpublished coauthored materials.

Utilizing in-depth phenomenological interviews and photography, this study sought to gain insights into how the lived experiences and intersections of transgender and disability identity impact high school experiences. The collection of interview data and photography allowed for a deeper understanding of the essence of the phenomenon under study. The aim was to understand the ways in which the complexities of ‘transgender’ and ‘disability’ identities impact high school experiences.
The analysis of the data lead to six key themes including: gender as fluid, society and identity, conflation of identities, mental health, changes in school and difference as strength. This dissertation offers a more complete picture of the needs and barriers transgender youth with disabilities face to inform future research and practice. Results from this study extend the current research and provide a deeper understanding of the needs and challenges of transgendered youth with disabilities. Findings from this study also support implications for how educators work with transgender youth with disabilities and how schools can be more inclusive in meeting their needs.

Naturality in Heegaard Floer Homology
Gartner, Michael
Lipshitz, Robert
Geometric Topology
Heegaard Floer Homology
Low Dimensional Topology
Let Man* denote the category of closed, connected, oriented and based 3-
manifolds, with basepoint preserving dieomorphisms between them. We show that
the Heegaard Floer invariants yield functors from Man* to the category of transitive systems in the projectivized category of Z[U]-modules,
whose values agree with the Heegaard Floer invariants dened by Ozsvath and
Szabo. In doing so, we will see that these projective functors actually come from a
transitive system, in the projectivized homotopy category of chain complexes over
Z[U]-Mod, associated to each 3-manifold. This extends work of Juhasz, Thurston
and Zemke, who showed that there are analogous functors coming from the Heegaard Floer invariants defined over F2. We discuss several applications of
these naturality results, and use them to introduce and investigate an invariant of
nonorientable 3-manifolds coming from Heegaard Floer Homology. This dissertation
includes material that has been submitted for publication.

Since the advent of the public World-Wide-Web in 1992, networked computer communication has rapidly become integral to the daily lives of many North Americans. Many researchers in the humanities and social sciences debate the potential power and nature of the effects of these new forms of communication. Some scholars see dangers in the changing forms of “media literacy,” but others see the Internet engendering new levels of democratic debate at grassroots and personal levels. However, much of this research still lacks the basic methodological rigor necessary to make reasonable claims about actual individual human communicative behavior on the Internet. By melding the behavioral ethnographic methods of folklore studies and socio-linguistics to postmodern methods of rhetorical analysis, this dissertation explores the general hypothesis that Internet media encourage the use of negotiative rhetorical strategies in the everyday expression of vernacular religious belief. By participating in the specific Christian Fundamentalist discourse known as Dispensationalism, this dissertation establishes methods for locating and classifying particular Internet expressions based on their revelatory, experiential, and/or negotiative rhetorical strategies. The hypothesis is explored through a series of five cases related to Protestant Dispensationalism: early American Puritan and Quaker autobiography, 1994 and 1995 Christian e-mail lists, the 1996 and 1997 e-mail campaign of the “Heaven's Gate” religious group, and 1999 and 2000 amateur Dispensationalist web-site builders. Based on e-mail, web-site, questionnaire, and face-to-face interview data, the results of this research have shown that the hypothesis overestimated the power of the Internet to encourage negotiative attitudes in deeply religious individuals. Although the Internet expressions of belief seem to have taken on a style of negotiation, little actual negotiation about religious beliefs or values occurred on the Internet among those documented. Instead, there was a constant exchange of similar ideas which seem to primarily function as attitudinal posturing. Though strong positions were taken and expressed to large and diverse audiences, only a very few individuals were willing to adjust their previously held beliefs as a result of their experiences with Internet communication.

H and O Isotope Systematics in Volcanic Glass: Hydration Experiments and their Application to Volcanic and Hydrothermal Processes

The goal of my dissertation is to expand the application of H2O, δD, and δ18O in silicic volcanic glass to a greater diversity of pyroclast cooling, degassing, and rehydration histories. All pyroclasts must cool from magmatic temperatures and those at Earth’s surface, which can affect the distribution of H2O and its constituent isotopes in glass. Vapor hydration experiments of silicic glass constrain H2O solubility and diffusivity in glass between 175°C and 375°C. Modeling of the experimental data demonstrates that H2O diffusivities approximate extrapolations of high temperature relationships, but H2O solubility in glass is at least 1.5 wt% higher than predicted by extrapolating H2O solubilities in melts. Next, I evaluate the time evolution of δD in experimental glasses with an isotope reaction-diffusion model. Below 250°C, the δD fractionation between glass and H2O vapor (103lnαg-v) is between −25‰ and −33‰, overlapping with low temperature D/H 103lnαglass-H2O values. The boundary composition of the model controls the bulk glass composition rather than reactions of H2Om to OH− internal to the glass during hydration. These results enable interpretation of H2O, δD, and δ18O in natural samples over a large range of temperature conditions, which I first apply to cooling ignimbrites from the 7700 BP Mt. Mazama eruption and the 1912 Novarupta eruption. This work also highlights that glass hydration of pumaceous can occur rapidly over days to months and lock in a δD value that records local meteoric waters as a paleoclimate proxy. Finally, I show that glass rehydration can occur even more rapidly on the timescales in eruptive volcanic plumes with meteoric water sources using H2O–δD compositions in a suite of tephras from the 2009 eruption of Redoubt volcano. Waning influence of a summit glacier has no effect on tephra compositions, suggesting moist air entrainment is the rehydration source. Furthermore, H2O diffusion modeling illustrates that the temperatures at which erupted material comes into contact with an H2O is more important than the quench rate of the pyroclast as rehydration can occur at the fastest quench rates if H2O is available. Tephra H2O–δD compositions therefore record water-glass interactions in multiple volcanic environments.

The current study examines second dialect acquisition of North Korean refugees living in Seoul. A total of 14478 stops were measured from each of 22 Pyongyang North Korean standard (NK) and Seoul South Korean (SK) speakers. First, stops of NK and SK have been directly compared to each other by measuring VOT, F0, and H1-H2. In addition to providing acoustic analyses of stop production in NK and SK, effects of various sociolinguistic factors on stop production have been statistically investigated. Moreover, topic-based style shift and interlocutor effects on their production have examined. First, NK and SK stops were significantly different in terms of VOT and F0. The NK speakers still primarily rely on VOT as a cue to distinguish the stops, unlike the SK speakers. In addition, three different speech conditions significantly influenced the NKs’ stop production. Specifically, in reading nonce word task, the NK speakers produced more NK-like stops. However, in a conversation with a SK interviewer, they produced more SK-like stops. Acquisition of SK stops were also significantly related to sociolinguistic factors. Other than age of acquisition and length of residence in Seoul, Identification and Language attitudes were significant predictors in producing SK-like stops. The more they identified themselves as South Korean, the more they produced SK-like VOT patterns. Moreover, the more positive attitudes they expressed towards SK, the better they produced SK-like F0 patterns. Topic-based style shift of NK speakers was also uncovered. Topic itself did not influence the NKs’ stop shifting; however, topic x stance effects significantly affected their stop production. When they talked about North Korea negatively, they performed SK identity, by producing more SK-like stops. Finally, interlocutor effects were also significant. With the SK interviewer, they used clear speech strategy, by enhancing both VOT and F0 cue in stop production. In contrast, with the NK interviewer, their VOT and F0 were less differentiated, showing more casual stop production. This study highlights the process of acquiring new manner of stops in SK and predictors that influence better SK stop production, by providing speech data from more vulnerable and marginalized population in a society.

The purpose of the current study was to investigate factors that influence the believing of child sexual abuse (CSA) disclosures. CSA is a major public health issue (WHO, 2002). Approximately one third of females and one sixth of boys will be sexually abused before the age of 18 (Kendall-Tackett, Williams, & Finkelhor, 1993), yet most victims do not disclose the abuse until long after it occurred, if ever (London, Bruck, Ceci, & Shuman, 2005). Not disclosing has many deleterious effects for victims including not stopping chronic abuse and not receiving therapeutic interventions (Ullman, 2003). Fear of not being believed is a major deterrent against disclosure (Goodman-Brown, Edelstein, Goodman, Jones, & Gordon, 2003) and not being believed when one discloses has negative psychological and physiological health effects (Ullman, 2003). Therefore, the question about factors that influence believing disclosures is related to public health.

Medieval Aquitaine was a vibrant region in terms of its politics, religion, and
culture, and these interrelated aspects of life created a fertile environment for musical
production. A rich manuscript tradition has facilitated numerous studies of Aquitanian
sacred music, but to date most previous research has focused on one particular facet of
the repertoire, often in isolation from its cultural context. This study seeks to view
Aquitanian musical culture through several intersecting sacred and secular concerns and
to relate the various musical traditions to the region's broader societal forces. Saint-Martial
in Limoges and Toulouse, two musical and cultural centers, illustrate the wider
cultural context in Aquitaine, and a survey of select manuscripts shows the development
of a musical tradition. An examination of three disparate pieces shows that the repertoire
as a whole is a more unified part of Aquitanian culture than previously recognized.

By the Will of the King: Majestic and Political Rhetoric in Ricardian Poetry
Driscoll, William
Laskaya, Catherine
Canterbury Tales
Confessio Amantis
Geoffrey Chaucer
Henry III
John Gower
Second Barons' War
The stories we tell give meaning and coherence to our political situation; they reproduce, interrogate, and, at times, challenge the discourse of authority. Thus, when the political situation changes so do our narratives. In the thirteenth century, responding to a majestic rhetoric of vis et voluntas (force and will), the barons strengthened the community of the realm by turning it into a powerful collective identity that fostered political alliances with the gentry. By The Will of the King demonstrates how Ricardian poetry was shaped by and responded to the conflict between majestic and political rhetoric that crystallized in the politically turbulent years culminating in the Second Barons’ War (1258-1265). By placing Gower’s Confessio Amantis and Chaucer’s Canterbury Tales in dialogue with this political tradition, I demonstrate how narrative became a site of conflict between vertical, cosmic descriptions of power and horizontal realities of power, a conflict from which the contours of a civic habit of mind began to emerge.
Over the past twenty years, scholars have begun to investigate the evolution of this habit of mind in the late Middle Ages. By looking at the narrative practice of Gower and Chaucer through the lens of thirteenth-century political innovation, I extend and fill in this depiction of a nascent political imaginary. Each poet responds to the new political circumstances in their own way. Gower, placing the political community at the center of Book VII of the Confessio, rigorously reworks the mirror for princes genre into a schematic analysis of political power. For Chaucer, political rhetoric becomes visible at the moment that the traditional majestic rhetoric of kingship collapses. The Canterbury Tales, as such, restages the conflict of the thirteenth century in aesthetic terms—giving form to the crisis of authority. Ultimately, Ricardian poetry exposes and works through an anxiety of sovereignty; it registers the limits of a majestic paradigm of kingship; and reshaping narrative, aesthetic, and hermeneutic practice, it conjures a new political imaginary capable of speaking to and for a community which had emerged during the reign of Henry III.

Chern Character

We give a formula for the Chern character on the DG category of global matrix factorizations on a smooth scheme $X$ with superpotential $w\in \Gamma(\O_X)$. Our formula takes values in a Cech model for Hochschild homology. Our methods may also be adapted to get an explicit formula for the Chern character for perfect complexes of sheaves on $X$ taking values in right derived global sections of the De-Rham algebra. Along the way we prove that the DG version of the Chern Character coincides with the classical one for perfect complexes.

Korean calligraphy went through tremendous changes during the twentieth century, and Jung Hyun-bok (1909-1973), a gifted calligrapher, played an important role in bringing about these changes. This thesis focuses on one of Jung's most mature and refined works, "Using the Peak of the Five Elders as a Brush," owned by the Jordan Schnitzer Museum of Art. In addition to translating and explicating the poems on the screen, through a close examination of both the form and content of the work I explore how it reflects Jung's values, intentions, and background. This thesis also addresses the question of why some critics have classified Jung as a professional artist and considers some of the ways in which he actually cultivated and projected an image of himself as a traditional literatus.

Sublime Views and Picturesque Embellishments: Westward Expansion and “Progress” in Gilded Age Guidebooks Illustration
Hernandez, Carolyn

History of Photography
Literary Analysis
Print Culture
Romanticism
The American West
Victorian Illustration
In this thesis I apply literary analysis to railroad guidebook illustration (1880-1890) to argue that the framing and decorative embellishments aided the nineteenth century reader in imagining an idealized version of the Western landscape. Although rail travel was quick and removed from the physical experience of the landscape, guidebook illustrations highlight the picturesque aspects of the Western environment and supplement the rail travel experience by guiding the viewer through a contemplative and romantic reading of the landscape. Guidebooks immersed the reader in the progressive narrative of the guidebooks. The authors utilize language that assumes the readers are riding along the transcontinental path as they read, and the imagery serves to engage the readers’ imaginations and guide the viewers in viewing the picturesque and idealized version of the Western landscape.

War by Other Means: Environmental Violence in the 21st Century
Hall, Shane
LeMenager, Stephanie
Climate change
Environmental justice
Latinx literature
Migration
Militarism
Violence
This dissertation studies the intersections of militarism, climate change, and environmental justice in U.S. literature and popular culture since the end of the Cold War. The project identifies different mechanisms enacting environmental military violence through discursive analysis of literary and cultural texts, and considers the ideas, values, and beliefs that support environmental military violence. In each chapter I trace a different dynamic of environmental violence structured through the logics of U.S. counterinsurgency theory by examining what I call “narrative political ecologies”—cultural texts that center concerns of ecology and broadly defined political economy. Chapter I establishes the stakes and questions of the dissertation. The next two chapters investigate the dynamics of environmental violence depicted within narrative political ecologies. Chapter II investigates how eruptive interpersonal violence secures more insidious, hidden forms of slow environmental violence in Héctor Tobar’s The Tattooed Soldier. Chapter III considers the U.S.-Mexico Borderlands and the environmental military violence responsible for the deaths of undocumented migrants by examining Luis Alberto Urrea’s The Devil’s Highway and the Electronic Disturbance Theater’s Transborder Immigrant Tool. Chapter IV turns to potential f wars and conflicts that may be caused by climate change as they have been depicted in speculative fiction. In novels depicting climate migrants, such as Octavia Butler’s Parable of the Sower (1993) and Parable of the Talents (2014), I show that even politically progressive, intersectional approaches to environmental endangerment naturalize conflict and occlude dialogic solutions to environmental change. The final chapter traces how the environmental refugee has become a paradigmatic figure in climate change discourse, particularly the aspects of this discourse where issues of national security are articulated. At the center of these texts is the figure of the migrant and narratives of migrations, and I argue that the figure of the environmental migrant offers a privileged vantage on the constitutive forces of the Anthropocene. The dissertation identifies the specific literary and rhetorical techniques that authors use to contest environmental militarization and expand the U.S. public’s capacity to creatively and compassionately reason around increased flows of environmental migrants— issues of vital importance for humane climate change adaptation.

First, I investigate the effect of public policy on health use and health outcomes, exploiting variation in the generosity of Medicaid eligibility to low income pregnant women across states and over time to identify an effect on common, yet costly, pregnancy complications. I provide new evidence on this important question from a nationally representative sample of hospital discharges for 12 states between 1989 and 2001. Second, I explore heterogeneity in individual demand for health risk reductions. Utilizing individual stated-preference data from matching surveys conducted in both Canada and the United States, I employ the Value of a Statistical Illness Profile framework to investigate differences in average willingness-to-pay (WTP) for health risk reductions across the two different cultures. Although existing literature has allowed for systematic variation in age to explain differences in health care demand, the differences in WTP have not been explained through systematic variation across other socio-demographic characteristics, subjective risks of the diseases in question, or differences between the Canadian and U.S. health care systems. I extend the literature by controlling for an expanded set of observable individual heterogeneity and comment on the degree to which estimates can be applied across cultures to inform varying policy decisions. The third paper studies factors affecting adolescent health risk behavior. Previous study finds that community size and the degree to which social networks are interconnected affect three economically significant outcomes: the frequency of adolescent misbehavior in school, degree of perceived safety in school, and grade performance. Other research has suggested peer effects on smoking behavior and drinking behavior. I investigate the degree to which social connectedness impacts adolescent health, specifically looking at outcomes for drinking and smoking, and the degree to which these effects can be disentangled from more commonly studied "peer effects" in health behavior.
