Global Stabilization Of The Mitochondrial Proteome Is Associated With Extreme Anoxia Tolerance In Austrofundulus Limnaeus Ws40ne Cells, Chelsea Hughes, Meranda M. Corona, Dietmar Kültz, Jason E. Podrabsky

Biology Faculty Publications and Presentations

Background: Austrofundulus limnaeus is an extremophile vertebrate native to small temporary ponds of Venezuela. Embryos of A. limnaeus must survive variable and often extreme conditions, including long periods of anoxia. Neuroepithelial cells derived from these embryos, WS40NE cells, provide a unique tool to understand how the proteome changes in response to anoxic stress. Results Using label-free proteomics, 19,604 peptides and 3487 proteins were quantified in normoxic, 4d anoxic, and 24 h recovery WS40NE cells. Of these, 2612 proteins (74.9%) were statistically significantly differentially abundant in at least one comparison: 1988 comparing normoxia to 4 days anoxia (57.0%), 923 comparing 4 …

God's Not Neutral: Narrative Tropes, Spiritual Warfare, And The Construction Of Evangelical Political Identity In American Christian Fiction, Evelyn L. Mccullough

Dissertations and Theses

Evangelical Christian fiction has reached tens of millions of readers and viewers during the most sustained period of evangelical political mobilization in American history, yet its narrative construction remains largely unexamined. This study asks how recurrent tropes in this genre build the attitudinal and emotional preconditions for political engagement. Combining systematic qualitative content analysis of eight texts spanning four decades (1986–2024) with Critical Discourse Analysis grounded in van Dijk's sociocognitive framework, it traces how storytelling devices connect theological belief to political behavior. The analysis reveals a single organizing logic: the corpus holds one regressive heroic disposition constant while making it …

Without A Map: A Lived Experience Study Of The Paths People Create Through Homelessness, Kathleen P. Conte, Susan Avila, Desiree' J. Duboise, Carlton Bone, Marisa A. Zapata, Transformational Research For Equity And Experience In Shelter (Trees) Committee

Homelessness Research & Action Collaborative Publications and Presentations

The Pathways to Housing Study examines how people experience and navigate homelessness and the systems intended to help them move toward stable housing. Conducted in Multnomah County, Oregon, the study used a participatory mixed-methods design co-led with the TREES lived experience committee. The first phase was reported in April 2026 included surveys with 541 people with current or recent experience of homelessness. The second phase, reported here, used in-depth interviews and journey mapping with 29 participants to explore how pathways through homelessness unfold over time and across service systems.

Findings demonstrate that homelessness pathways are rarely linear. Participants described entering …

Omoiyari In The Performance Of American Learners Of Japanese: An Analysis Of Second Culture Compilation And Pragmatic Transfer, Shizuka Fukuo

Dissertations and Theses

This thesis examines omoiyari (consideration for others) as a Japanese cultural theme by examining how it is enacted by native Japanese speakers and American learners of Japanese during an invitation scenario. L2 learners' incorporation of the target culture's linguistic and behavioral norms is essential to fully participate in ways that read as natural in that culture. However, relatively little research has examined the extent to which L2 learners are able to enact culturally embedded norms in L2 interaction. Furthermore, little attention has been paid to explaining the cultural theme of omoiyari as it is enacted in an invitation role-play provides …

The Cross-Section Of Empirical Evidence And Personal Experience: A Deeper Look At School Resource Officers Through The Lens Of Demarcus A. Jenkins' Research On The Public Opinion Of Their Potential Removal From Public Schools, Quin Armstrong

University Honors Theses

Following the 2020 Black Lives Matter and Anti-Police movements, there were many discussions across the nation about possible changes to law enforcement operations. Among these discussions included specific discussions about what to do about law enforcement officers stationed in schools. These law enforcement officers are known as school resource officers, or SROs.

The focus of this thesis is specifically on Portland, Oregon's Portland Public School (PPS) district's decision to sever ties with the Portland Police Bureau, and what may have contributed to that ultimate decision. This is accomplished through an analysis of a research paper written by fellow Criminal Justice …

What Can You Say When You Can't Say Everything?, Lori Dorfman, Liana B. Winett, Katherine Schaff, Pamela Mejia

OHSU-PSU School of Public Health Faculty Publications and Presentations

Today's decisions about what and how to communicate about population health occur amid very real fears and expectations of harsh reprisal that have had far-reaching impacts, both for people's health and for the health professions. It is in this context that health researchers must share their findings with the public and policy makers, prevent confusion, and avoid harming groups already facing systemic barriers to health. In every communication context-from research papers to quotes on the nightly news-people must make thoughtful choices about what to say. Communication, therefore, is always an act of selection that requires both a clear purpose and …

Developing Field And Spaceflight Microscopy, Nikki Johnston

Dissertations and Theses

Designing for spaceflight favors the reduction of unnecessary features and cost-cutting, whether thisbe computation, hardware, or procedure. Resources are spent toward fortification and mission success over convenience. Such design goals paired with the relatively smaller budgets of academia lead us to do as much as we can in-house and use open-source as much as we can without compromising mission success. We also believe that thoroughly testing technology in extreme environments on earth is necessary for the success of a flight instrument. We focus on microscopy for life detection. I have spent my time here learning methods of hand-building microscopes to …

“Turn The Faucet”: Right-Wing Hydrosocial Imaginaries Of Irrigation Water In The Western United States, Alexander Reid Ross, Thien-Kim Bui, Alida Cantor

Geography Faculty Publications and Presentations

The second administration of United States President Donald Trump has taken an authoritarian, centralized approach to governance in the United States. Water management is one area in which the president has attempted to show dominance. This research theorizes President Trump’s concept of water in the United States West as a “hydrosocial imaginary” in which the release of water from rivers and reservoirs indicates virility, action, and power, instead of liberal cautiousness and prudence. By ordering the release of two billion gallons of water from California’s Central Valley into the dry Tulare Basin one hundred miles north of Los Angeles for …

The Freedom Myth: How Ski Culture's Hidden Conformity Reveals The Unconscious Power Of Brand Belonging, Isabel R. Phillips

University Honors Theses

Purpose: Ski culture sells freedom and enforces conformity. This review asks what unconscious behavioral patterns hold that contradiction in place, and how brands capitalize on it to manufacture belonging.

Design/Methodology/Approach: A narrative literature review across consumer psychology, behavioral neuroscience, sociology, and ski industry research. No primary data were collected. Four accounts of consistency-seeking are synthesized into one framework, then applied to three ski industry cases at ascending scales and tested against a comparative case from Spanish football.

Findings: Belonging is a conditioned response, and conditioning requires a stable stimulus. Consistency is therefore the precondition of belonging rather than a constraint …

Preparing Inclusive Educators: The Impact Of Fieldwork Experience On Preservice Teachers’ Knowledge, Skills, And Confidence In Working With Students With Disabilities, Adrian Jung

Northwest Journal of Teacher Education

This study examined preservice teachers’ confidence in working with students with disabilities across Elementary (n = 44), Secondary (n = 43), and Special Education (n = 52) programs. Using a quantitative pretest–posttest survey design, participants completed an adapted version of the Special Needs Confidence Scale before and after student teaching. Descriptive statistics and Tukey post hoc analyses were conducted. Results indicated overall increases in confidence following fieldwork, with Special Education preservice teachers reporting consistently higher confidence than Elementary and Secondary peers. Findings highlight the role of targeted preparation and field-based experiences in supporting inclusive teaching readiness.

Radical Republican Citizenship For A Mobile World, Alex Sager

Philosophy Faculty Publications and Presentations

Migrants invariably and unavoidably experience domination under the nation-state centered concepts, categories, and institutions that structure our political thinking. In response, we need to build new forms of citizenship, including local, regional, transnational, and supranational forms of belonging, accompanied by meaningful, democratic, political power. In this paper, I examine historical and present-day alternative models of political organization as possible viable alternatives to state-centric liberal democracy. It begins the task of assessing these models using radical republican theory that grounds non-domination in the active and equal participation of people subject to power. I have three broad aims. First, we need to …

Lessons From The Club Homeschool Capstone: Testing, Data Discipline, And The Computer Science Curriculum, Shane Brown

University Honors Theses

This thesis looks at the CLUB Homeschool Capstone project to argue that Portland State University's Computer Science curriculum should introduce testing and data quality discipline earlier and more intentionally than it does now. As team lead of a seven-person team, I coordinated sprint planning, communicated with the sponsor, and developed custom Discourse plugins that enhanced an existing forum platform instead of creating a separate application database, as requested by the sponsor. The project's requirements document called for a formal testing plan, but our team lacked the practical experience to implement one. This gap became evident through my internships as a …

Identity, Needs, And Conflict Online: Understanding Cultural Fragmentation In The Black Diaspora, Imhile Omosede Dora Akpata

Dissertations and Theses

This study examines how identity formation, intra-diaspora tensions, and social media interactions contribute to fragmentation within the Black diaspora. While existing scholarship, including work by Godfried Asante and Elizabeth Chacoko has emphasized the fluid and socially constructed nature of Black identity, less attention has been given to how these processes operate in practice across diverse diasporic groups and how they are intensified in digital environments. This research addresses this gap by analyzing how individuals negotiate Black identity, how tensions emerge within the diaspora, and how social media shapes and amplifies these dynamics.

Drawing on Social Identity Theory developed by Henri …

Toxic Relationships: Characterization Of A Putative Virally Encoded Toxin In The Thermophilic Archaeal Fusellovirus Ssv1, Jonathan C. Abshier, Patrizia L. Alpapara, Guasåli Tomokane, Kenneth M. Stedman

Center for Life in Extreme Environments Publications

Mechanisms for the maintenance of chronic viruses are poorly understood, particularly for archaeal viruses. Here, we identify the product of Sulfolobus spindle-shaped virus 1 (SSV1) ORF a291 as a putative virally encoded toxin required for growth inhibition but dispensable for viral replication and virion production. Viruses lacking ORF a291 replicated their genomes and formed morphologically normal spindle-shaped particles, yet failed to inhibit the growth of uninfected Saccharolobus solfataricus. Substitution of residues at a predicted N-terminal signal peptide cleavage site abolished growth suppression without affecting replication, suggesting that secretion is essential for toxin function. Despite primary sequence divergence among fusellovirus …

Macro Social Work Education And Practice Over 1980–2024 Through Multiple Lenses: A Systematic Review Of The Empirical Literature, Bowen Mcbeath, Nguyen Thi Bich Thao

School of Social Work Faculty Publications and Presentations

Over the past 40 years, conceptual and empirical scholarship on macro social work has grown, particularly as the social work profession has turned to macro practice to respond to crises of neoliberalism and increasing social development needs. Using a systematic literature review with a sequential mixed-methods (quant→Qual) study design, we synthesize over four decades of empirical research (1980–2024) on master’s-level macro social work education, practice, and professional identity development. Our findings testify to the growth and diversity of macro practice from the perspective of social work educators, students, and alumni. Yet we find that this trend is accompanied by significant …

Anoxia Tolerant Dna Replication Is Supported By Atr Kinase In The Annual Killifish Austrofundulus Limnaeus, Riley Roth-Carter, Erin Helms, Joshua C. Saldivar, Jason Podrabsky

Biology Faculty Publications and Presentations

Hypoxia and anoxia suppress cell proliferation due to an increase in replication stress and activation of DNA damage checkpoints. Embryos of the annual killifish Austrofundulus limnaeus tolerate prolonged anoxia, indicating improved genomic stability under oxygen starvation. We investigated the cell cycle regulation of the anoxia tolerant killifish embryonic cell line PSU-AL-WS40NE during anoxia. Live-cell imaging confirms continued proliferation of WS40NE cells for the first 24 h of anoxia with minimal cell death. Fluorescence imaging shows that cells accumulate in G1 after the first day in anoxia with a rapid entry into S phase upon reoxygenation. Pharmacological inhibition shows a reliance …

Trust And Signaling: An Exploratory Study Of Residential Attitudes Towards Energy Efficiency Advisors And Outdoor Media, Hal T. Nelson, Ivana Osmanovic

Public Administration Faculty Publications and Presentations

As the building sector shifts toward community-led energy efficiency (EE) initiatives to mitigate the climate crisis, scaling adoption requires understanding behavioral drivers. This study examines key drivers of EE measure adoption: perceived non-energy benefits, trusted advisors, and behavioral signaling. This research contributes to the energy policy and social science literature by empirically linking social trust with signaling preferences. It extends existing EE adoption decision theories by identifying distinct clusters of “expert” versus “close” advisors across demographic groups. Data from an experimental survey (n = 238) in Portland, Oregon, were analyzed using principal component analysis (PCA) and multivariate regression modeling. Results …

From Policy To Practice: Analyzing Inclusive Education Strategies In Nigerian Internally Displaced Persons (Idps) Camps, Chukwuyem Joel Arimie, Williams Okotie Dr

Hatfield Graduate Journal of Public Affairs

Through high-quality education delivery, inclusive education indicates the pursuit of social justice for all marginalized societies. The study examines how the Edo camp's internally displaced people are impacted by inclusive education policies. Relevant policy and regulatory frameworks pertaining to inclusive education in Nigeria were examined in the research. Because the Hope for the Needy Foundation provides for the educational needs of the children in the camp, interview responses suggest that despite the policy frameworks, strategies for the effective execution of the policy in the IDP camp have not yet been put in place. The article makes the case that the …

Unspent Donations In Donor Advised Funds - Policy Recommendation, Oriel Nolan-Smith

Hatfield Graduate Journal of Public Affairs

Billions of dollars are sitting in Donor Advised Funds, delaying support for charitable organizations seemingly at odds with the intent of U.S. charitable tax policy. With no requirement for annual distribution nor timelines for disbursement, Donor Advised Funds allow individual and institutional donors to postpone directing funds to charitable organizations - despite already claiming tax benefits. As a result, some DAFs distribute less than 5% of assets annually, while many of the institutions managing the DAFs continue collecting fees.

Two complementary policy interventions are recommended: (1) the issuance of a federal regulation requiring annual minimum distributions from all DAFs, and …

Desert Desires And The War On Terror: Pre- And Post-9/11 Sheikh Romances, Leena Altamimi

Book Publishing Final Research Papers

The existence of sheikh romances as a subgenre has prevailed for well over a century in Western literature. Therefore, would one be able to discern whether the book cover imagery as well as the textual content showcases any tangible differences pre and post 9/11, and America’s “war on terror” campaign? A total of five books are observed: The Sheik by E.M. Hull published in 1919, Sarah Holland’s Desert Destiny published in 1991, Loreth Anne White’s The Sheik Who Loved Me and Penny Jordan’s Possessed by the Sheikh (both published in 2005), and lastly Crowned for the Sheikh’s Baby by Sharon …

Resisting Dualism In Contemporary Movement Building: Lessons From The Zapatista Movement On Creating Assertive, Insurgent, And Generative Praxis, Nico Killian

University Honors Theses

The common struggle of social movements, revolutionary and otherwise, in the contemporary era is how to establish a collective capable of asserting its politics via grassroots organizing in the face of the logic of global capitalism that atomizes communities, reconfigures the role of the state, and unleashes the fragmentizing and simultaneously totalitizing forces of the global market. Discourse regarding effective movement building in the contemporary era often falls into two dualistic avenues of resistance - complete autonomy that rejects any engagement or affiliation with political structures out of fear that it would result in demobilization through co-optation or negotiating a …

"Your Problem Is Not At All An Uncommon One": Visibility, Black Men, And Sexual Orientation In The Anti-Apartheid And Civil Rights Movements, Wren Addison Weddell

Dissertations and Theses

The South African Anti-Apartheid Movement and the American Civil Rights Movement are two of the most well-known examples of racial liberation movements, but there are few scholarly works that offer comparisons between the two. Furthermore, the experiences of people who fall outside the bounds of heteronormative society are often overlooked in historical research on both movements. Despite the dearth in research, there are several key factors that are revealed when comparing the lives of Black non-heterosexual men among the activists for both of these movements, including the role of the global community, unique local cultures, and how the state polices …

Improved Method Of Evaluating Gas-Phase Air Cleaners Considering Adsorption And Desorption Mechanisms To And From Internal Test Chamber Surfaces, Casey Douglas Coffland

Dissertations and Theses

Portable air cleaners are playing an increasingly important role in managing indoor air quality in response to pressing issues like wildfire smoke events. Smoke is a complex mixture of gases and particulate matter; while established test methods exist for particulate matter, the dynamic behavior of gaseous pollutants is not well accounted for in current test methods. This is because prevailing air cleaner testing methods typically treat background losses as irreversible, whereas gases can engage in partitioning to and from test chamber surfaces. Ignoring these sorption interactions causes inaccurate estimation of an air cleaner's impact.

A new approach has been developed …

Perception And Identity Through The Deconstruction Of Images, Ember Gulden

University Honors Theses

Human lives are informed by images, which allow us to understand a moment from the past while transforming the way we remember it. A photograph is a representation of what was physically in front of a camera. However, the image after its capture holds no singular identity and is malleable, similar to memory. I use photography and mixed-media collage in my artistic practice to explore how perception and identity is affected by the images we consume. My BFA project "This Doesn't Have To Be The End" examines the complex nature of identity through the transformation of personal photographs into pixel-like …

Junk Journaling For Graphic Designers: Analog Play & Process In An Increasingly Digital Design Landscape, Kristina Rosgen

University Honors Theses

This thesis explores junk journaling as an accessible analog practice for young graphic designers experiencing digital fatigue, creative stress, and perfectionism. Through historical research, a hands-on workshop, and an interactive Readymag website, the project shows how junk journaling can help designers reconnect with play, process, physical materials, and the joy of making.

The Kashmir Conflict After The Abrogation Of Articles 370 And 35a Of The Indian Constitution: Geopolitical Dynamics And Human Security Implications, Rizwan Ali

Dissertations and Theses

The abrogation of Article 370 of the Indian Constitution on August 5, 2019, revoked the special autonomous status of Jammu and Kashmir (J&K) under the Indian administration. It further bifurcated it into two Union Territories under central Indian control. The move came amid a severe security lockdown and communication blackout that lasted for months. It was followed by instrumental legal, social, and economic developments that directly affected the area’s disputed status and the human rights of its residents. This research examines the geopolitical and human security implications of the abrogation and subsequent developments through a qualitative, analytical design, integrating Edward …

So You Didn't Write The Next Great Novel (And How To Move Forward Knowing You Probably Won't), Adriana Stanzione

University Honors Theses

This thesis discusses the relationship between creative ambition and the paralyzing effects of perfectionism within the writing process. By analyzing this relationship via a lens on philosophy, psychoanalytic theory, and personal experience, it argues that the obligation and pressure to produce "good" work can often prevent sincerity and creative momentum. Divided into several sections, it also delves into ideas like inspiration and the revision process, tying in my own experiences with drafting my first manuscript, which resulted in years of writer's block and cynicism. The thesis also considers how cultural conditions contribute to creative stagnation, and deconstructs the concept of …

Strategic Anti-Transgender Policy Diffusion: Interest Groups, Courts, And The Two-Track Politics Of Gender Regulation, Henry Danford

University Honors Theses

This thesis analyzes the strategic diffusion of anti-transgender policy in the United States following the passage of Idaho House Bills 500 and 509 in 2020. It argues that conservative lawmakers and advocacy organizations employed a coordinated "two-track" policy strategy in which transgender sports bans served as highly visible and politically popular mode legislation while identity-document restrictions advanced more quietly through courts and administrative policy. Drawing on policy diffusion theory, the Advocacy Coalition framework, and minority stress theory, the study combines qualitative policy analysis with quantitative analysis of Household Pulse Survey mental health data and Media Cloud new coverage data from …

Custom Sbc Gps Tracking And Geocaching Carputer Software Development And Implementation, Joshua A. Davis

University Honors Theses

This thesis argues that hardware-integrated capstone projects develop software engineering skills that traditional coursework cannot replicate. A team of eight developers built a GPS tracking system on a Raspberry Pi 4 over two academic terms, integrating real-time position streaming, the APRS amateur radio protocol for network-independent location sharing, and PostGIS spatial queries for "new road" detection. The system implements SmartBeaconing for adaptive GPS data reduction, achieving approximately 80% storage savings while preserving route fidelity. The project exposed challenges absent from classroom assignments: hardware debugging without stack traces, cross-layer integration failures, and coordination overhead when deploying to unfamiliar architecture; demonstrating that …
