Item Open Access Data, images, and R programming language code for age-depth modeling a lake sediment record(2024-10-14) Gavin, Daniel G.Langlois Lake in western Washington contains evidence of overbank flows (floods) onto an alluvial fan surface from the adjacent Tolt River. A six-meter sediment core from the lake, and a freeze core of the surface sediments, reveals the timing of these overbank flows as distinct silt units in the sediment. Radiocarbon dates and Pb-210 measurements provide a basis for aging these layers. However, due to the very different rates of sedimentation of the silt vs organic segments of the core, there is a complicated relationship between depth in the sediment and age of the sediment. Typical methods have simply removed the "slumps" of the rapidly-deposited material; this is a subjective step and difficult to apply for long cores with many such events. The method used here, originally used in two papers (Colombaroli and Gavin 2010, Colombaroli et al. 2018), uses an estimate of the fluvial silt component of sediment (from color or density) as a proxy for sedimentation rate. The R code (R programming language) and data sets here accompany an application of this method to Langlois Lake. We also provide image files of the sediment record which this method depends.

Three species and two separate genera are described in the area, but previous research lacks statistical support for this level of variation. We use coefficients of variation (V) on measurements of dentition and astragali of hypertragulid specimens designated Hypertragulus hesperius, Hypertragulus minutus, and Nanotragulus planiceps as a metric for determining whether there were multiple species present in the population. Asymptotic and modified signed-likelihood ratio V equality tests show that V values of anterior-posterior molar length and transverse molar width vary significantly when comparing single species of modern ecological analogs (Muntiacus muntjak, Muntiacus reevesi, and Tragulus javanicus) to groupings of a combined population. However, the V equality tests on dental and postcranial measurements yield almost no significant results when comparing variation in the extinct John Day hypertragulids to an extant population comprised of a single species. Similar comparisons between astragali measurements of hypertragulids and T. javanicus express no significant difference in the level of variation from the combined population to a modern single species. The low level of variation in the hypertragulids and the lack of differentiation between dental characters of individuals does not statistically support the hypothesis that there were multiple species present in the population, suggesting either that cryptic species may be present but impossible to identify without soft tissue remains, or there may have been taxonomic over-splitting of a single hypertragulid species in the John Day region.Item Open Access Esports buffs: the perceived role of fans and fandoms in U.S. collegiate programs(Frontiers in Sports and Active Living, 2024-09-11) Cote, Amanda C.; Rahman, Md Waseq Ur; Foxman, Maxwell; Wilson, Andrew; Harris, Brandon C.; Can, Onder; Hansen, Jared C.Introduction: Collegiate esports—organized competitive gaming—has expanded rapidly in the United States, drawing in student players, broadcasters, and support staff, as well as university employees. Universities have invested financially in esports, hoping to capitalize on gaming fandom to attract prospective students and enhance campus community integration. Little research, however, addresses collegiate esports fandom in depth. Methods: Drawing on thirty-one in-depth interviews with collegiate esports players, student workers, program directors, and administrators, this article investigates how collegiate esports participants perceive and discuss their fans. Results: We identify three central themes related to fans in the dataset: discussions of fans’ role in the collegiate esports environment, comparisons between esports and traditional sports fans, and concerns about the underutilization of fans within collegiate esports spaces. Subsequently, we theorize these themes through existing research on professional esports and traditional collegiate sports fandoms, as well as through the concept of “fan labor,” or how the productive work of fans provides value to the nascent industry. Discussion: This article thus not only specifically explores how collegiate esports programs are normalizing fan labor as an essential part of their practices, but also questions who benefits from this relationship and how. Investigating collegiate esports fans as an under-researched group additionally provides a new perspective on how fan labor integrates with media industries more broadly.Item Open Access Visibility for Indigenous Students and Their Languages: Analysis of Home Language Data in Federal Reports across Seven U.S. States(Social Sciences, 2024-08-16) Perez Baez, Gabriela; Zyskind, Karen; Dorman, Meagan; Medina, YesseniaThere is an increasing number of children in the U.S. classified as English Learners (ELs). Accurately identifying and supporting ELs in their academic settings entails understanding their non- English language experiences. This study presents findings from language reporting practices from seven U.S. states by examining how states account for the linguistic diversity of Indigenous Mesoamerican languages. Our findings reveal varied state approaches and underscore the limitations of current federal guidance, which limits the recognition of students’ non-English language experiences. We advocate for updating language identification practices and policies and propose a new framework for accurate language identification and continuous monitoring of student linguistic diversity.Item Open Access Molecular basis of product recognition during PIP5K-mediated production of PI(4,5)P2 with positive feedback(Journal of Biological Chemistry, 2024-08-03) Duewell, Benjamin R.; Faris, Katherine A.; Hansen, Scott D.The ability for cells to localize and activate peripheral membrane-binding proteins is critical for signal transduction. Ubiquitously important in these signaling processes are phosphatidylinositol phosphate (PIP) lipids, which are dynamically phosphorylated by PIP lipid kinases on intracellular membranes. Functioning primarily at the plasma membrane, phosphatidylinositol-4-phosphate 5-kinases (PIP5K) catalyzes the phosphorylation of PI(4)P to generate most of the PI(4,5)P2 lipids found in eukaryotic plasma membranes. Recently, we determined that PIP5K displays a positive feedback loop based on membrane-mediated dimerization and cooperative binding to its product, PI(4,5)P2. Here, we examine how two motifs contribute to PI(4,5)P2 recognition to control membrane association and catalysis of PIP5K. Using a combination of single molecule TIRF microscopy and kinetic analysis of PI(4)P lipid phosphorylation, we map the sequence of steps that allow PIP5K to cooperatively engage PI(4,5)P2. We find that the specificity loop regulates the rate of PIP5K membrane association and helps orient the kinase to more effectively bind PI(4,5)P2 lipids. After correctly orienting on the membrane, PIP5K transitions to binding PI(4,5)P2 lipids near the active site through a motif previously referred to as the substrate or PIP-binding motif (PIPBM). The PIPBM has broad specificity for anionic lipids and serves a role in regulating membrane association in vitro and in vivo. Overall, our data supports a two-step membrane-binding model where the specificity loop and PIPBM act in concert to help PIP5K orient and productively engage anionic lipids to drive the positive feedback during PI(4,5)P2 production.Item Open Access Discovery of Oligocene-aged mammals in Glacier National Park (Kishenehn Formation), Montana(Geodiversitas, 2024-06-24) Famoso, Nicholas; Calede, Jonathan J., 1988-; Kehl, Winifred A.; Constenius, Kurt N.The Kishnehn Formation crops out in Glacier National Park of northwest Montana where a rich fossil record of plant macrofossils, pollen and spores, insects, terrestrial and aquatic mollusks, and fish has been unearthed. Past research has also described an extensive mammal fauna from the Eocene (Uintan-Chadronian). Oligocene-aged fossil mammals have been reported before, but none has ever been published in the peer-reviewed literature. Here, we present the first Arikareean-aged fossil mammals from the Kishenehn Formation, the youngest fossil mammals ever discovered in the park. The fossils consist of a set of lower jaws of the leptomerycid Pronodens transmontanus (Douglas, 1903) and a partial lower jaw of the rodent Paciculus montanus Black, 1961, both endemics of the northern Rocky Mountains. These new fossils enable us to explore the morphological variation in Pronodens Koerner, 1940 and Paciculus Cope, 1879. Our analyses suggest the existence of a single widely distributed and sometimes locally abundant species of Pronodens, which may co-occur with a rare and very large second species. Our revised diagnoses for the genus and species show the need for additional work on this little-studied artiodactyl genus. Similar efforts on the systematics of cricetid rodents will benefit from building upon our analysis of tooth morphology in Paciculus to shed light on the rise of leidymines. The last fossil we describe, partial paired dentaries of Miohippus Marsh, 1874, is the northern-most occurrence of the genus in the Rocky Mountains and shows the potential for future work in the Kishenehn Formation to enable the study of faunal change across the Eocene-Oligocene boundary in the northern Rocky Mountains.Item Open Access New occurrences of mammals from McKay Reservoir (Hemphillian, Oregon)(Journal of Paleontology, 2024-05-07) Orcutt, John D.; Schmer, Christiana J.; Lubisich, Jeffrey P.; Abrams, Lacy T.; Famoso, NicholasEncompassing global cooling, the spread of grasslands, and biogeographic interchanges, the Hemphillian North American Land Mammal Age is an important interval for understanding the factors driving ecological and evolutionary change through time. McKay Reservoir near Pendleton, Oregon is a natural laboratory for analyses of these factors. It is remarkable for its small vertebrate fauna including rodents, bats, turtles, and lagomorphs, but also for its larger mammal fossils like camelids, rhinocerotids, canids, and felids. Despite the importance of the site, few revisions to its faunal list have been published since its original description. We expand on this description by identifying taxa not previously known from McKay Reservoir based on specimens collected during fieldwork and through reidentification of previously collected fossils. Newly identified taxa include the borophagine canid Borophagus secundus (Matthew and Cook, 1909), the camelids Megatylopus Matthew and Cook, 1909 and Pleiolama Webb and Meachen, 2004, a dromomerycid, and the equids Cormohipparion Skinner and MacFadden, 1977 and Pseudhipparion Ameghino, 1904. Specimens previously assigned to Neohipparion Gidley, 1903 and Hipparion de Christol, 1832 lack the features necessary to diagnose these genera, which are therefore removed from the site's faunal list. The presence of Borophagus secundus, Cormohipparion, and Pseudhipparion is especially important, because each occurrence represents a major geographic range extension. This refined understanding of the fauna lays the foundation for future studies of taphonomy, taxonomy, functional morphology, and paleoecology—potentially at the population, community, or ecosystem levels—at this paleobiologically significant Miocene locality.Item Open Access Outshine with the Superfine Frankenstein Pipeline at Timberline: Visualizing Cost Per Use in Power BI(The Acquisitions Institute at Timberline Lodge, Oregon, 2024-05) Harlan, Lydia; Buxton, Kristin; Hayden, GabrieleLooking to establish a current and reproducible cost per use analysis for continuing resources, three members of University of Oregon Libraries explored ways to ingest, store, and visualize cost and usage data. Our presentation describes how we developed a pipeline using Alma, COUNTER5, SUSHI, APIs, Python, and Power BI to create an easily refreshed dashboard for collections assessment. Our tool shifts the time investment from manually harvesting usage statistics to interpreting the data and sharing it with stakeholders. By establishing this automated pipeline, we created an up-to-date dashboard and reproducible model that we can share with others and improve upon in future permutations. We hope that attendees of this presentation will feel inspired to use visualization to tell stories and become curious about constructing a data pipeline of their own.Item Open Access Lori Robare: Tribute in honor of her retirement(Nelson Poynter Memorial Library, 2024-04-18) Hixson, Carol G.Originally published as a blog posting on April 18, 2024 in honor of Lori Robare's retirement from the University of Oregon Libraries.Item Open Access Recasting Twitch: Livestreaming, Platforms, and New Frontiers in Digital Journalism(Routledge: Taylor and Francis Group, 2024-04-05) Foxman, Maxwell; Harris, Brandon C.; Partin, William ClydeDespite Twitch’s dominant position in Western livestreaming markets, institutional journalists rarely produce content on the platform. This paper investigates how journalistic practices, cultures, business models, and institutions approach Twitch through three empirical sites: The Washington Post’s experimentation with the app, left-leaning political influencer Hasan Piker, and the pro-QAnon 24/7 “news” channel, Patriots’ Soapbox. The cases demonstrate how newsmaking on Twitch flouts traditional journalists’ ideological and occupational boundaries, exploiting the platform’s features and affordances to enroll the audience in a live broadcasting experience.Item Open Access The politics of indigeneity: decolonizing historical memory and education in Colombia(Pedagogy, Culture and Society, 2024-02) Cortes, DiegoThis article explores how the Misak (Guambianos) from the Colombian southwest are revitalising their collective memory and militant politics in a nation that has historically prioritised its Spanish heritage. Through the analysis of twenty-month collaborative research conducted by three Misak University (MU) students and the article’s author (a non-Indigenous Colombian affiliated with a university from the Global North), the article claims that political engagement results from this community’s autonomous educational institutions and pedagogical practices. The MU is one of these Misak autonomous efforts engaging with non-traditional pedagogies, such as caminar el territorio, to promote a ‘militant indigenous identity’ committed to their cultural differentiation. These educational practices evolved from other methods for memory reproduction embraced by the Misak since colonial times. As the tearing down of the statues of Spanish conquistadores in 2020 shows, the Misak’s educational efforts have cultivated a new indigenous generation that seeks to make a political and cultural impact beyond their territory.Item Open Access World Press Trends Outlook 2023-2024(WAN-IFRA (World Association of News Publishers), 2024-01-25) Radcliffe, Damian; Nel, François; Henriksson, Teemu; Roper, DeanAfter the sobering read seen in our 2022-23 report, this year’s World Press Trends study strikes a more cautiously optimistic note, with more than half of the respondents conveying a positive outlook about their companies’ business prospects for the foreseeable future. This is despite publishers grappling with challenges on various fronts, including elevated inflation and interest rates, surging paper and printing expenses, continual shifts within advertising markets and audience behaviours, as well as wider geopolitical uncertainty reflected in conflicts in Ukraine, the Middle East and elsewhere. Meanwhile, wider strategic challenges such as the surge of Generative AI, changing relationships with platforms and continued challenges to press freedom and freedom of expression, also continue to vex many journalists and publishers. In response, news publishers are inevitably looking closely at their revenue strategy, investment priorities, areas of focus, cost management, and their stance on areas such as AI and other technologies. We delve into these themes extensively within this report. This report is primarily based on the findings of an online survey distributed to WAN-IFRA members and other senior media executives between July and September 2023, and was available in four languages (English, French, Spanish and German). Survey participants were typically members of the senior team at a newspaper or a newspaper group. Based on the information provided by our respondents, a third (66%) are C-Suite (CEOs, Publishers, Managing Directors). A further third is either a Commercial Director/Heads of Strategy or Executive Editor. We received 175 complete responses from 60 nations around the world. Using classifications developed by the World Bank, 58% of respondents come from developed economies and 42% from developing economies. Our sample also features a wide range of different countries with respondents coming from countries as diverse as Argentina, Canada, Russia, and Indonesia. They also came from some of the world’s largest media markets, including Germany, India, the United States, and the United Kingdom. Through the data and insights that they provided, we are able to comprehend the attitudes of today’s industry leaders in a variety of business and editorial roles. Their observations, regarding the sector’s present and future, can be seen throughout this report. As ever, we want to express our appreciation to everyone who participated in this annual survey. This report would not be possible without their contributions.Item Open Access Microtomography of an enigmatic fossil egg clutch from the Oligocene John Day Formation, Oregon, USA, reveals an exquisitely preserved 29-million-year-old fossil grasshopper ootheca(Parks Stewardship Forum, 2024) Lee, Jaemin; Famoso, Nicholas; Lin, AngelaEggs are one of the least understood life stages of insects, and are poorly represented in the fossil record. Using microtomography, we studied an enigmatic fossil egg clutch of a presumed entomological affinity from the Oligocene Turtle Cove Member, John Day Formation, from the National Park Service-administered lands of John Day Fossil Beds National Monument, Oregon. A highly organized egg mass comprising a large clutch size of approximately 50 slightly curved ellipsoidal eggs arranged radially in several planes is preserved, enclosed in a disc-shaped layer of cemented and compacted soil particles. Based on the morphology of the overall structure and the eggs, we conclude that the specimen represents a fossilized underground ootheca of the grasshoppers and locusts (Orthoptera: Caelifera), also known as an egg pod. This likely represents the oldest and the first unambiguous fossil evidence of a grasshopper egg pod. We describe Subterroothecichnus radialis igen. et isp. nov. and Curvellipsoentomoolithus laddi oogen. et oosp. nov., representing the egg pod and the eggs, respectively. We advocate for adopting ootaxonomy in studying fossil eggs of entomological affinities, as widely practiced with fossil amniotic eggs. An additional 26 individual and clustered C. laddi collected throughout the A–H subunits of the Turtle Cove Member suggest the stable presence of grasshoppers in the Turtle Cove fauna, and we discuss the paleoecological implications. Oothecae have convergently evolved several times in several insect groups; this ovipositional strategy likely contributed to the fossilization of this lesser-known ontogenetic stage, enriching our understanding of past insect life.Item Open Access Prenatal care in urban China: Qualitative study on challenges and coping mechanisms(SSM - Qualitative Research in Health, 2024) Nagao, HarukaThis study aims to identify challenges that women face in accessing prenatal care services in urban China and their coping mechanisms to deal with the challenges. We conducted semi-structured interviews in June and July in 2019 with 38 women who had experience of childbirth within the last five years. Through interviews, this study pays particular attention to a quality of prenatal care services by focusing on women’s experiences in seeking for such services. The findings suggest that most participants had access to standardized prenatal care services but faced two challenges: long wait time and short doctor-patient interaction time. These challenges stem from overcrowded hospitals. The findings also illuminate power and information asymmetry between doctors and patients. Women leverage social networks with friends, colleagues, and former classmates to fill in the gap of short doctor-patient interaction by obtaining relevant information about pregnancy and prenatal care services. The analyses of interviews and a social networking site also suggest that online social networks play a similar role to fill in the informational gap. Still, social networks remain a coping mechanism rather than a fundamental solution to the systemic issues within the public health system.Item Open Access Breathing-Based Meditation for Improving COPD Burden: A Mixed Single- Case and Qualitative Approach(LISDEN Publishing Inc., 2023-12-19) Lin, Ting-fen; Linville, Deanna; Nese, Rhonda N. T.; Seeley, John; Shune, SamanthaChronic obstructive pulmonary disease (COPD) impacts the physiological and psychoemotional aspects of life. COPD-related secondary sequelae also synergistically interact with each other. For example, dyspnea affects the severity of breath, body functions, and the mind (e.g., anxiety, panic, fear). Such negative psycho-emotional states can further negatively impact the breath and the body (e.g., increased dyspnea). Given the breadth of the impact of COPD on multiple facets of health and well-being, it is essential to investigate comprehensive approaches to managing COPD, simultaneously addressing the mind, body, and breath. Sudarshan Kriya Yoga (SKY), a breathwork meditation program, has previously yielded a wide range of physiological and psycho-emotional benefits but has not been explored in individuals with COPD. Using single-case multiple-baseline and qualitative phenomenology methodologies, this study investigated 1) the relation between dyspnea and SKY and 2) the feasibility and general perceived effectiveness of SKY among individuals with COPD. Nine individuals with varying severities of COPD participated. Data collection included ratings of perceived dyspnea (work of breathing, shortness of breath, dyspnea-related distress, dyspnea-related anxiety) and semi-structured in-depth interviews. Results suggest that SKY is feasible and acceptable for individuals with COPD. Additionally, the results demonstrate proof of concept that SKY can help alleviate aspects of the COPD disease burden related to the mind, body, and breath as well as reduce the cyclical effect of the disease sequelae. Larger-scale trials are warranted, but this study is the first to support SKY as a viable complementary and integrative health approach for individuals with COPD.Item Open Access Automating for Success: Making Invisible Work Visible(University of Oregon, 2023-10-27) Harlan, Lydia; Buxton, Kristin; Hayden, GabrieleKnowing your value and optimizing your time can help meet your professional and institutional goals. We describe how an ad-hoc team of people from three different departments, with three different primary goals, were able to successfully complete a project to automate the collection and dissemination of cost-per-use data for continuing resources, saving our colleagues many hours of work, and creating a dashboard that requires little maintenance. In the process we learned a bunch of current technology—Power BI, APIs, and data visualization, to name a few that we can apply to other projects.Item Open Access Addressing Discipline Equity: The Inclusive Skill-Building Learning Approach (ISLA) an Alternative to Exclusionary Discipline(2023-09-25) Pimentel-Mannan, Irin A.; Nese, Joseph F.T.; Newson, Alex; Nese, Rhonda N.T.; Kjellstrand, JeanExclusionary discipline practices are frequently utilized in schools despite decades of research indicating their ineffectiveness (American Psychological Association Zero Tolerance Task Force, 2008; Losen & Skiba, 2010; Muñiz 2021). Research shows that removing students from the classroom does not change student behavior, is administered disproportionately to historically marginalized and minoritized groups, and is linked to the school-to-prison pipeline and lower academic achievement (Barnes & Motz, 2018; Losen & Martinez, 2020; Noltemeyer et al., 2015). This study explores the impact of the Inclusive Skill-Building Learning Approach (ISLA), an instructional and restorative alternative to exclusionary discipline practices, on discipline disproportionality. Pre-intervention, implementation, and post-intervention discipline data for 6th through 8th grade students were collected to understand the relation between ISLA and disproportional discipline data by race and gender. The findings suggest that ISLA is an effective tool for reducing overall in-school and out-of-school suspension rates as well as the risk indices for out-of-school suspensions for students of color, yet there is still a need for intervention adaptations to address specific disparities in exclusionary discipline practices. Research findings, study limitations, and implications and directions for future research and practice are further discussed.Item Open Access Redefining News: A Manifesto for Community-Centered Journalism(Agora Journalism Center, 2023-09-21) Radcliffe, Damian; Lawrence, Regina; DeVigal, AndrewThis forward-thinking report makes the case for embracing a more inclusive, community-focused model of journalism, one that prioritizes listening to and collaborating with communities to produce relevant, equitable and impactful news and storytelling. The report features an actionable framework to put the principles of Community-Centered Journalism into practice and explains how this approach differs from traditional models of journalism, with potential benefits including rebuilding trust, tackling inequities, and fostering civic engagement.Item Open Access The Fear of Personal Death and the Willingness to Commit to Organ Donation(Sage, 2023-09) Kogut, Tehila; Pittarello, Andrea; Slovic, PaulIn three studies, with samples from different countries (the United States and Israel) and religions (Christians and Jews), we found that individual levels of fear of death significantly predicted lower willingness to register as organ donors (Studies 1 and 2). Moreover, after being asked about their organ donation status (i.e., whether they are registered as donors), fear of death significantly increased among unregistered people. This did not occur among registered people, who had already faced the decision to become donors in the past (Study 2). Finally, providing non-registered (non-religious) people with a defense strategy to manage their fear of death increased their willingness to sign an organ donation commitment, partially by increasing their feelings of hopefulness. The implications of these findings for increasing organ donation registration are discussed.Item Open Access Instructional and Restorative Alternatives to Exclusionary Discipline: A Guide to Implementing the Five Components of the Inclusive Skill-building Learning Approach (ISLA)(2023-07-21) Nese, Rhonda; Santiago-Rosario, María Reina; Nese, Joseph F.T.; Triplett, Danielle; Malose, Saki; Hamilton, Jillian; Izzard, Sara; Newson, AlexIn this brief, we outline the five components of the ISLA model, as well as steps that school and district teams can take to begin implementing these practices within their positive behavioral interventions and supports (PBIS) framework. Key Takeaways • The ISLA model was created to support teachers, staff, and students by focusing on preventative strategies that promote affirming equitable learning environments within schools. • Building and sustaining positive relationships with students helps increase engagement and decrease disruptive behaviors. • The ISLA Process gives school staff and students instructional and restorative tools for dealing with challenging situations.
