Examining Equitable Participation With K-12 Teacher Leaders, Eva Thanheiser, Kathryn Elizabeth Roman, Ruth Heaton

Mathematics and Statistics Faculty Publications and Presentations

Many organizations and researchers in mathematics education call for antibias practices, but addressing hidden biases remains challenging. Equity QUantified In Participation (EQUIP), a quantitative tool designed to analyze classroom participation patterns by social markers, helps teachers identify these subtle inequities. This paper describes a professional development (PD) intervention introducing EQUIP to five teacher leaders (TLs) and three coaches in a predominantly Latine district, focusing on setting up EQUIP to identify and address participation inequities in their classrooms. The TLs implemented EQUIP in their classroom and gathered participation data twice. Findings revealed that TLs took up EQUIP in different ways and …

Expanding And Mainstreaming Sociohydrology Toward Transdisciplinary Praxis, Shinichiro Nakamura, Heidi Kreibich, Melissa Haeffner, Jenia Mukherjee, Giuliano Di Baldassarre, Maiko Sakamoto, Mikiko Sugiura, Günter Blöschl, Taikan Oki, Murugesu Sivapalan

Environmental Science and Management Faculty Publications and Presentations

Since its development in the early 2010s, sociohydrology has deepened our understanding of the long-term coevolution of humans and water by integrating insights from both the natural and social sciences, while also fostering an interdisciplinary community. Its modus operandi to date has been to focus on emergent phenomena, manifesting as unintended consequences, in a variety of contexts. The compound disaster that struck Japan’s Noto Peninsula in 2024, and similar experiences in other parts of the world, underscore the urgent need for systemic approaches that are co-developed by academia and practitioners and focus on context-specific solutions. This perspective piece thus calls …

Exploring The Composition Of Forest Collaboratives In Northeastern Oregon, Lee K. Cervany, Rebecca J. Mclain, Kristen Wright

National Policy Consensus Center Publications

Community-based collaboration has been touted as an effective model for forest governance because it promotes democratized decision-making and stakeholder engagement to address landscape-scale problems. Forest collaboratives are assumed to be heterogeneous, consisting of stakeholders with a diverse range of interests. Few studies have systematically explored variables associated with collaborative composition. We identify six elements of collaborative composition for investigation: size, stakeholder diversity, balance, locality–diversity, core attendance, and cross-participation. This exploratory study examines five forest collaborative groups in eastern Oregon (USA). We analyzed meeting minutes over an 18-month period to track attendance and evaluate who shows up and at what frequency. …

The Answer To Perimenstrual Distress Is Not Automatically Prescription: Review Of Allopathic And Integrative Approaches To Mental Health Care For Pms & Pmdd Symptoms, Grace Oja

University Honors Theses

Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) affect a notable percentage of people who menstruate. PMS/PMDD have a wide range of symptoms that negatively impact mental well-being and quality of life. This review is the culmination of a database search to review current allopathic treatments for PMS/PMDD, which often include oral contraceptives and antidepressants, and explore evidence-based methods for integrative and alternative treatments to address some of the limitations of standard allopathic care, including limitations on which symptoms they address and side effects. This paper aims to examine how integrative medicine may expand existing treatments for PMS and PMDD …

Who Bears The Burden? An Assessment Of Vulnerability And Resilience To Consecutive Disasters In The Portland Metro Region, Idowu Ajibade, Jason Sauer, Matthew Walter, James M. Done, Ming Ge, Elliot Gall, Aswatha Raghunathasami, Paul C. Loikith, Chris Lower, Heejun Chang, Arun Pallathadka, E Mae Sowards

Geography Faculty Publications and Presentations

Climate-related disasters threaten urban areas worldwide, yet gaps remain in understanding how multiple stressors interact to shape resilience. This study examines exposure, vulnerability, and resilience across three consecutive extreme events in the Portland metro area: the September 2020 wildfire-related air pollution, the February 2021 snowstorm, and the June 2021 heatwave. We used geographically weighted regression and Spearman rank correlation analysis to investigate relationships between hazard impacts, the social vulnerability index (SoVI), Baseline Resilience Indicators for Communities (BRIC), and proximity to community-based organizations (CBOs) in 416 census tracts. Our analysis reveals strong spatial correlations between wildfire-related air pollution, winter storm impacts, …

Regional And District Trends In Oregon’S Post-Pandemic School Enrollment And Achievement, Madhu Narayanan

Northwest Journal of Teacher Education

Oregon has been highlighted as a state with large student enrollment changes after the pandemic, as well as persistent learning loss. Unlike many other states in the nation, this learning loss has persisted. This paper goes beyond the statewide trends to examine regional and district level patterns in both enrollment changes and learning outcomes. One major finding is that while districts in all regions experienced enrollment changes, Large Urban and Suburban districts had notable enrollment declines. These declines were driven by a decrease in White students. Meanwhile, Suburban districts had increases in Asian, Black, and Multiracial students. Another finding is …

Illuminating Two Secondary Schoolteachers’ Praxes On A ‘Terrain Of Freedom:’ Lessons For Teacher Education, Paul Tarc, Nicholas Ng-A-Fook, Tasha Ausman, Catherine James

Northwest Journal of Teacher Education

This paper attunes to the stated focus of this special issue—teacher subjectivities on a terrain of freedom—to consider the qualities, possibilities and limits of teachers’ praxes and development upon this ‘terrain.’ In response to the call, we explore three critical questions: 1) Where does the teacher’s freedom lie amidst required protocols and standardization?; 2) Can teachers transcend how they have been conceived and conditioned?; and 3) How can teachers engage in transformative development? Through a "poetics of teaching," inspired by Hansen (2004), we frame teaching as a curricular and pedagogical art form that melds interdisciplinary, intellectual, aesthetic, and …

Surges In The Shadows: Stock-Flow Adjustments And Public Debt Spikes, Leandro Andrian, Cesar Rodriguez, Oscar M. Valencia

Economics Faculty Publications and Presentations

This paper investigates the drivers of public debt surges in 172 countries from 1980 to 2021, focusing on stock-flow adjustments (SFA)—discrepancies between annual debt changes and budget deficits. Using survival analysis methods, we find that a one percentage point increase in the SFA to GDP ratio raises the hazard rate of a debt surge by 16%, with stronger effects in advanced economies (28%) compared to emerging markets (15%). Conditional on an increasing debt trend, higher SFA significantly increase the probability of a debt spike materializing. We address potential self-selection with an IV approach based on fiscal transparency, emphasizing that accurate …

Impact Of Oceanographic Gradients And Marine Heatwaves On The Picophytoplankton Community In The Northern California Current System, Kristin E. Forgrave, Carey P. Sweeney, Melissa Steinman, Anvita U. Kerkar, Timothy M. Pettit, Anne W. Thompson

Biology Faculty Publications and Presentations

The Northern California Current (NCC) system is a productive coastal ecosystem with a mosaic of temporal and spatial features. The phytoplankton community plays a crucial role in supporting the rich ecosystem and economically important fisheries of the NCC. Our study integrates data across two years (2022-2023) and multiple transects to investigate the community composition of two major phytoplankton groups in the NCC: picocyanobacteria and photosynthetic picoeukaryotes (PPE). The abundances and cell sizes of the phytoplankton were measured using flow cytometry. We found PPE present at similar concentrations in both summer and winter, while picocyanobacteria were much more abundant in the …

Homework, Households, And Hurdles: The Unexpected Drivers Of Student Graduation Perceptions, Daniel Alhassan, Zahra Fatah, Priscilla Mansah Codjoe, Caroline Bena Kuno, Dorcas Ofori-Boateng

Mathematics and Statistics Faculty Publications and Presentations

Students’ perceptions of their likelihood to graduate are important determinants of their academic engagement, yet these perceptions remain understudied. This study, which is based on the 2021 Monitoring the Future survey of 8th- and 10th-grade students in the United States, uses machine learning algorithms to identify the most important factors that influence these perceptions. Among the tested models, random forest provided the best classification performance. Using permutation-based feature importance, we identified frequent participation in schoolwork, maternal education, paternal education, and homework completion as the most important predictors of students’ graduation perceptions. These results highlight the importance of targeted and well-coordinated …

Kolmogorov–Smirnov-Based Edge Centrality Measure For Metric Graphs, Christina Durón, H. Kravitz, Moysey Brio

Mathematics and Statistics Faculty Publications and Presentations

In this work, we introduce an edge centrality measure for the Helmholtz equation on metric graphs, a particular flow network, based on spectral edge energy density. This measure identifies influential edges whose removal significantly changes the energy flow on the network, as indicated by statistically significant p-values from the two-sample Kolmogorov–Smirnov test comparing edge energy densities in the original network to those with a single edge removed. We compare the proposed measure with eight vertex centrality measures applied to a line graph representation of each metric graph, as well as with two edge centrality measures applied directly to each …

Mediating Role Of Self-Efficacy In The Association Between Fatigue And Depressive Symptoms In Females With Rheumatoid Arthritis, I-Yu Hsiao, Hanoch Livneh, Chieh-Tsung Yen, Ming-Chi Lu, Wei-Jen Chen, Tzung-Yi Tsai

Counselor Education Faculty Publications and Presentations

Background and Objectives: Extant research on the relationship between fatigue and depression in people with rheumatic diseases portrays a divergent picture. While caring for persons with this medical condition, one issue that represents individual confidence in carrying out specific tasks, namely self-efficacy level, has attracted significant attention. Yet, the information regarding whether self-efficacy may pose a clue linking these two major symptoms is still unknown. The aim of this study, therefore, is to examine whether self-efficacy mediates the association between fatigue and depressive symptoms among persons with rheumatoid arthritis (RA). Materials and Method: A cross-sectional study of 224 …

The 2 Sigma Genus Concept In Mammalogy: Lessons From Lasiurus, Amy B. Baird, Janet K. Braun, Mark D. Engstrom, Burton K. Lim, Michael A. Mares, Luis A. Ruedas, John C. Patton, John W. Bickham

Biology Faculty Publications and Presentations

Species concepts are well established and apply across diverse groups of organisms; however, there is no consensus on what defines higher taxonomic groups. The genus rank is important to taxonomists because it comprises part of the scientific name of an organism. A consistent and biologically meaningful method for determining generic status is needed for taxonomic stability and utility. Lasiurine bats are a group for which there is disagreement on how many genera to recognize. Some authors argue for splitting this group into three genera based on morphology, genetic divergence, and time of divergence; others argue that a single genus should …

Hegemonic Entrepreneurial Masculinities In Patriarchal Contexts: Exploring Men's Entrepreneurship In War-Torn Territories, Doaa Althalathini, Theodore A. Khoury, Nick Rumens

Business Faculty Publications and Presentations

This article examines how the war-torn context in Iraq has affected men’s entrepreneurship and entrepreneurial masculinities. Drawing on the entrepreneurship masculinities literature, Connell’s notion of hegemonic masculinity and in-depth interviews with 21 Iraqi men entrepreneurs, this article demonstrates the complex interplay between entrepreneurship, masculinity and patriarchal dynamics in the context of wars and economic instability in Iraq. Study findings show how Iraqi men often turn to entrepreneurship out of necessity to meet patriarchal expectations of them as primary providers for their families. We contribute to the literature on entrepreneurship, men and masculinities by demonstrating how entrepreneurship not only serves as …

Accounting For Stillbirths In Maternal Health Metrics: A Cross-Country Analysis Research In Context, Ursula Gazeley, Hallie Eilerts-Spinelli, Joshua Wilde, Hannah Blencowe, Li Liu, Wendy Graham, Veronique Filippi

Publications, Reports and Presentations

Background: Live birth is only one of four potential pregnancy outcomes, alongside stillbirth, miscarriage, and induced abortion. While morbidity and mortality associated with all pregnancy outcomes are included in the numerator of many maternal metrics, often only live births are included in the denominator. This inconsistency makes interpreting trends challenging and may exacerbate the deprioritisation of monitoring other pregnancy outcomes. We assess the effect of using (1) total births (live births and stillbirths) or (2) total pregnancies (total births plus miscarriages/induced abortions) as the denominator on estimates of maternal and pregnancy-related mortality ratios (MMR and PRMR). Methods: Using data from …

Religious Identity, Linked Fate, And Political Ideology: Explaining Civil Rights Philanthropy Among Muslim And Jewish Americans, Rafeel Wasif, Afshan Paarlberg, Shariq Siddiqui, David King

Public Administration Faculty Publications and Presentations

Social identity theory predicts that individuals prefer to give to people with the same identity as themselves. However, individuals have multiple identities that interact simultaneously. For instance, religion is an essential identity for many individuals, particularly those from racialized minority groups, such as Muslims and Jews, who are often discriminated against due to these identities. Moreover, individuals like to support faith-based causes. However, they may also feel that they have a linked fate identity, where they perceive a commonality with other persecuted minorities due to similar experiences of discrimination. Moreover, political ideology is another vital identity marker for many individuals. …

Strengthening Connections: A Randomized Controlled Trial Examining The Impact Of A Supervisor Support Intervention On Loneliness And Military Couple Relationships, Cynthia D. Mohr, Annamarie S. O'Neill, Jacquelyn M. Brady, Todd E. Bodner, Tori L. Crain, Leslie B. Hammer

Psychology Faculty Publications and Presentations

Social connection has been declining across the general population (i.e., the “loneliness epidemic”), though some groups, including military personnel, are experiencing particularly high rates. This has led to calls for a multilevel national strategy, including workplaces, to build social connection (U.S. Surgeon General, 2023). To answer this call, the present study draws on the wise intervention approach (Walton, 2014), multidimensional model of social connection (Holt-Lunstad, 2022), and models of the bidirectional relationship between sleep health and relationship functioning (Gordon et al., 2017; Troxel et al., 2007), to deliver a workplace intervention that builds social connection for military employees and their …

Speech and Hearing Sciences Faculty Publications and Presentations

Communication difficulties experienced by people with aphasia (PWA) cause disconnects between meaningful conversations and care received. The purpose of this study was to identify concepts PWA define as (1) the most critical facilitators to transitional care and communicative access success, and (2) transitional care and communicative barriers. A qualitative descriptive study design was utilized. Semi-structured interviews were conducted with six PWA and two communication partners and analyzed using directed content analysis, guided by the theory of Human Scale Development. Findings revealed that barriers and facilitators centered on three Needs: (1) Participation: Participation in life events was directly related to public …

Heightened Risk: Childhood Trauma And Anticipatory Grief Exacerbate The Impact Of Loneliness On Depressive Symptoms And Lps-Stimulated Cytokines In Dementia Caregivers, Kelly N. Brice, Jensine Paoletti-Hatcher, E Lydia Wu-Chung, Vincent D. Lai, Daniel L. Argueta, Michelle A. Chen, Itee Mahant, Bryan T. Denny, Charles Green, Luis D. Medina, Multiple Additional Authors

Psychology Faculty Publications and Presentations

Dementia spousal caregivers are at a disproportionate risk for adverse mental and physical health outcomes. Loneliness is associated with depressive symptoms and proinflammatory cytokine production among caregivers. Additionally, childhood trauma, anticipatory grief, and poor sleep quality are all associated with enhanced stress reactivity. This study used a cross-sectional design to investigate whether loneliness is associated with proinflammatory cytokine production and depressive symptoms in caregivers, and whether these relationships are strongest among caregivers who report high levels of childhood trauma, high amounts of anticipatory grief, or poor sleep quality. A sample of 111 dementia spousal caregivers provided blood samples and completed …

Exploring The Association Of Vitamin B12 Deficiency And Dental Health In Older Adults, Man Hung, Amir Mohajeri, Jacob Marx, Corban Ward, Martin S. Lipsky

Institute on Aging Publications

Background

Vitamin B12 plays a crucial role in overall health, yet its impact on dental health, particularly dental caries, remains underexplored. Older adults are at an increased risk of vitamin B12 deficiency and dental disease, but the relationship between these two factors is not well understood. This study examines the association between serum vitamin B12 levels and dental health in older adults using data from the NHANES 2011–2014 cycles.

Methods

A cross-sectional analysis was conducted using NHANES data from 1,907 participants aged 65 and older. Serum vitamin B12 levels were categorized as normal (>221 pmol/L), marginal (148–221 pmol/L), and …

The study aims to identify Passiflora incarnata as a practical, non-harmful, and cost-effective alternative to current modern anxiety medications. This study also emphasizes the need for further clinical trials to integrate Passiflora incarnata further into healthcare settings. Using a narrative review approach, this analysis will examine pre-existing empirical articles, all of which have been found on credible sites, are peer-reviewed, and have been published within the past twenty-five years. The data discussed …

Safe-Haven Ignorance: The Epistemic Refugee, Purya Rabet

PSU McNair Scholars Online Journal

This paper engages with the emerging field of ignorance studies. Per feminist critique, the classic “X knows that p” formulation in epistemology fails to account for the subjectivity and situatedness of X. Building on feminist and critical race theory contributions, this paper puts forward a positive theory regarding resistance to belief-revision. The inquiry concerns the relationship between X’s ignorance and X’s self. This paper interrogates defensive reactions to knowledge and their connection to the narrative sense of self. It introduces “safe-haven ignorance”—a psycho-sociopolitical defense mechanism—which occurs when an individual becomes hostile toward knowledge that contradicts their established self-narrative. This contradiction …

Who's Afraid Of Femininity? An Examination Of Hegemonic Masculinity And Envy, Shiloh R. Frost, Emily Shafer

PSU McNair Scholars Online Journal

The woman's rights movement has made strong progress over the past years, yet strict attitudes on how men and women should behave persist. Manhood is defined as being the polar opposite to womanhood, as any expression of femininity is treated as a threat to its dominant position within gender hierarchy. Research has shown that while women have managed incorporate traditionally masculine roles into womanhood, the same has yet to be done for manhood — specifically in the case of cisgender and heterosexual men. In fact, societal wide disdain towards the femininities persists despite attempts to challenge the gender hierarchy. This …

PSU McNair Scholars Online Journal

Why has mental illness in our children let alone society increased so significantly? In this paper I am doing a lit review to understand the need for a structured lesson plan of Social Emotional Learning (S.E.L.) and incorporating some techniques of social cognitive therapies for our children. This will be understood by comparing social cognitive therapies in Schizophrenia treatment that rewires healthy neural pathways from miswired neural pathways that are not functional in schizophrenia and the impact on a person with schizophrenia having difficulties to integrate into society while coping with their illness. I will do this by analyzing Theory …

The Role Of Neuroscience In Mental Health Management Within The Adhd Population, Kadi Rae Smith

University Honors Theses

Neuroscience-based educational interventions play a role in the management of Attention Deficit Hyperactive Disorder (ADHD), including the regulation of ADHD-correlated depression and anxiety. Existing research shows that elevated rates of depression correspond to anxiety within the ADHD community; approximately 8.83% of the global population. Social ostracization and isolation are established contributors to depression and anxiety which are commonly comorbid with ADHD. The need exists for further investigation of the beneficial impact that an accurate, biological understanding of how the brain works has on the mental health of the ADHD population, and by extension their families, education systems, and medical industries. …

Beyond The Genome: The Racialized Exposome, Flourishing, And Stress Biology In African Americans, A Non-Exhaustive Review, Enye Washington

University Honors Theses

Racial health disparities remain an enduring challenge in the United States, disproportionately impacting African American communities through higher rates of chronic disease and premature mortality. This non-exhaustive literature explores how the racialized exposome - a term denoting the totality of social, environmental, and structural stressors rooted in systemic racism - biologically embeds itself via stress-responsive pathways. Specifically, it examines the interaction between racial stress, flourishing, and key biological markers, including allostatic load and telomere length, considering the gut-brain axis. The review highlights robust evidence that chronic exposure to racial discrimination and structural adversity contributes to multisystem dysregulation and accelerated cellular …

Mindful Marcelo: The Process Of Writing And Illustrating A Culturally-Specific Children's Book For Early Psychoeducation, Liz Romero-Herrera

University Honors Theses

Socio-emotional learning (SEL) is imperative for young children to learn prosocial skills and how to identify and regulate their emotions. Most children begin to develop these skills in early childhood and depend on caregivers and teachers to model them. However, caregiver and teacher biases related to child gender and race can limit equitable access to high-quality SEL, placing male students of color at higher risk for maladaptive coping strategies. To address this gap, this thesis documents the creation of a culturally sensitive children's book focused on SEL concepts for young Latino boys. Throughout this thesis, I documented the process of …

Working Paper No. 100, Social Realism And Socialist Realism, Amanda F. Worman

Working Papers in Economics

This inquiry sees to establish that as a genre, “social realism” reflected values of the American system of market capitalism out of which this art style emerged. During the same timeframe, what has been categorized as “socialist realism” reflected values of the Soviet system out of which this art style also arose. The “Great Depression” that dogged the American economy and society through the 1930s, as well as the “Iron Fist” rule characteristic of Joseph Stalin’s heavy industrialization drive for Soviet Russia, appears to have promoted and shaped these two distinct but similar art styles under consideration, as responses to …

The Discovery, Communication, And Implementation Of New Geologic Findings: Examining The Cascadia Earthquake, Saylor Brainard

University Honors Theses

The Cascadia Subduction Zone, located off the Coast of the Pacific Northwest, is at risk of generating a 9.0 magnitude earthquake in the near future. Despite its significance, the discovery of the seismic potential of Cascadia didn't occur until 1987, when geologist Brian Atwater searched for non-traditional forms of earthquake evidence. As decades of continued research fleshed out Atwater's initial discovery, the implications associated with the discovery became apparent, presenting Washington and Oregon with the high probability that a massive earthquake will take place within the next century. Communicating the severity of this geologic discovery to both the public and …
