This study’s purpose was to explore the formation, significance, and impact of this partnership from the perspectives of staff and leadership members from both organizations. We conducted a case study through qualitative interviews with staff, participant observation, and debrief of leadership meetings. We completed a hybrid deductive–inductive thematic analysis of the data, followed by member checking with study participants and …

Abolition And Social Work: Dismantling Carceral Logics To Build Systems Of Care, Durrell M. Washington, Brittany Ribeiro Brown, Diana Ballesteros, Rebecca Lynn Davis

School of Social Work Faculty Publications and Presentations

Social work has historically operated as an extension of the carceral state, embedding policing, surveillance, and punishment into youth-serving institutions under the guise of care. This paper examines carceral seepage—the infiltration of punitive logics into social work practice—across child welfare, education, and juvenile legal, revealing how these systems function as interconnected circuits of criminalization rather than support. Using abolitionist frameworks, we critique social work’s complicity in punitive interventions and address common concerns about safety, scalability, and sustainability. Instead of reforming oppressive institutions, we argue for a fundamental transformation of social work, advocating for non-carceral models such as community-led crisis response, …

The Addition Of Chinese Herbal Medicines Is Effective As A Prophylactic Treatment Against Dental Diseases For Sjögren’S Syndrome Patients: Insight From Real-World Database, Ching-Ya Juan, Wei-Jen Chen, Hanoch Livneh, Ming-Chi Lu, Tzung-Yi Tsai

Leadership, Learning and Counseling Faculty Publications and Presentations

Background and Objectives:

Sjögren’s syndrome (SS) is a chronic autoimmune disease that affects the salivary glands and increases the risk of developing dental diseases (DDs). Chinese herbal medicines (CHMs) represent a promising alternative strategy for SS treatment; however, the association between CHMs and DD risk has not been confirmed. In this retrospective, cohort-based, nested case-control study, we explored whether or not combining CHMs with routine treatments for SS can reduce the chance of DDs.

Materials and Methods:

In the beginning, we recruited subjects aged 20–80 years with newly diagnosed SS who were free of DDs between 2001 and …

Industries, Self-Rated Health, And Status Characteristics: An Exploration Of Health In Industries At The Intersection Of Race/Ethnicity, Gender, And Disability, Emmanuel Legarreta

Dissertations and Theses

While industries, occupations, and health outcomes have been widely studied, research has neglected self-rated health (SRH) and the intersectionality of different status characteristics in various industries. Using an IPUMS version of the Current Population Survey, this study explores the possible relationships between industries and SRH. More specifically, it seeks to find if workers' disability status, racial minority status, or gender moderates (i.e., differentiates) the relationship between their industry and SRH. Findings show that certain industries are significant predictors of SRH, and that women with disabilities working in Mining and Construction, and Business and Repair Service have significantly worse SRH than …

Postsurgical Pain, Psychosocial Functioning, And Cannabis Use Among Adolescents And Young Adults Undergoing Gender Affirming Surgery, Eleanor Battison, Emily A. Kenyon, Corrin Murphy, Eline Lenne, Danielle N. Moyer, Sarah W. Feldstein Ewing, Anna C. Wilson

School of Social Work Faculty Publications and Presentations

Purpose: Little is known about transgender and gender expansive (TGE) adolescents and young adults (AYAs) pain and psychosocial experiences in the acute postsurgical period following gender-affirming surgery (GAS). This study describes pain symptomatology and psychosocial functioning within 1 month after GAS among TGE AYAs, examines immediate postsurgical associations of cannabis use with pain symptomatology, pain catastrophizing, and psychosocial functioning, and explores pain persistence, cannabis use, and psychosocial functioning in a subgroup of individuals 6 months after surgery.

Methods: AYAs (N = 64) underwent GAS at a large academic medical center in the Pacific Northwest between March 2019 and June …

Edge Percolation Centrality: A New Measure To Quantify The Influence Of Edges During Percolation In Networks, Christina Durón, Hannah Kravitz, Moysey Brio

Mathematics and Statistics Faculty Publications and Presentations

Numerous centrality measures exist to quantify the influence of edges within a network, with edge betweenness being one of the more well-known measures. However, such measures are inadequate in network percolation scenarios (e.g., the transmission of a disease over a transportation network of highways) as they fail to consider the changing percolation states of edges over time. This paper addresses this limitation by extending percolation centrality, a measure originally developed to evaluate the influence of vertices during a percolation process (i.e., a dynamic spread of a contagion) in the network, to the edge level. The proposed measure, edge percolation centrality, …

Probabilistic Intervals Around Population Forecasts: A New Approach With A Subnational Example Using Washington State Counties, David A. Swanson, Jeff Tayman

Publications, Reports and Presentations

Population forecasts produced by governments at all levels are used in the public sector, the private sector, and by researchers. They have been primarily produced using deterministic methods. This paper shows how a method for producing measures of uncertainty can be applied to existing subnational population forecasts while meeting several important criteria, including the concept of utility. The paper includes an assessment of the efficacy of the method by: (1) examining the change in uncertainty intervals it produces by population size and population growth rate; and (2) comparing the width and temporal change of the uncertainty intervals it produces to …

The Living Dead On Mount Athos: Monastic Politics Of Escape, Patrick Reilly

Dissertations and Theses

The Monastic Republic of Mount Athos is a unique and confounding political entity - both Greek and multi-national, democratic and theocratic, autonomous and subject to the European Union - with more than a millennia of history and institutional memory. While Athos has been amply appreciated for its religious, historical and cultural significance, the political institutions which govern this community have been neglected in the modern era and merit greater attention. Similarly, while much of the recent English-language literature on the topic focuses on the near-death and miraculous resurrection of Mount Athos in the 20th century, this work also tends to …

Grounded in Communities of Practice theory, this research amplifies student narratives to elucidate the relational and contextual factors that inform science identity, belonging, competence, and persistence in higher education. Study One draws upon interview data from fifteen participants in the BUILD program to analyze the role of recognition, particularly from expert scientists--in students' science identity development. This study aims to understand how racial and ethnic identity intersections influence the processes and impact …

(De)Centralized Water Futures: Key Dimensions Of Infrastructure, Governance, And Operations, Alicia Dailey Cooperman, Jenny Linder Rempel, Ellis Adjei Adams, Alida Cantor, Manuela Muñoz Fuerte, Jeremiah Osborne-Gowey, Nicole J. Wilson, Cassandra L. Workman, Melissa Beresford, Leila M. Harris, Multiple Additional Authors

Geography Faculty Publications and Presentations

Water system centralization and decentralization have variously been promoted as key to achieving household water security and Sustainable Development Goal 6.1. We argue that the lack of specificity with which scholars and practitioners use the terms centralization and decentralization limits our understanding of different water system configurations and their impacts. In this Primer, we provide a framework for thinking about levels of (de)centralization across three linked system dimensions: infrastructure, governance, and operations and maintenance. We encourage those analyzing water systems to characterize (de)centralization with respect to these multiple dimensions, as well as the system's broader political-economic and hydro-climatic contexts. Emphasizing …

The WTMP supports forecasts, historical analyses, and long-term planning efforts and advances previous modeling approaches by using an integrated modeling platform. This platform includes a data management system that acquires …

Enhancement Of Spin Transport Properties In Angled-Channel Graphene Spin Valves Via Hybrid Spin Drift-Diffusion, Samuel Olson, Kaleb Hood, Otto Zietz, Jun Jiao

Mechanical and Materials Engineering Faculty Publications and Presentations

Graphene has promise as a channel connecting separate units of large-scale spintronic circuits owing to its outstanding theoretical spin transport properties. However, spin transport properties of experimental devices consistently fall short of theoretical estimates due to impacts from the substrate, electrodes, or defects in the graphene itself. In this study, we fabricate both traditional non-local spin valves (NLSVs) and novel hybrid drift-diffusion spin valves (HDDSVs) to explore the impact of charge current and AC spin injection efficiency on spin transport. HDDSVs feature channel branches that allow investigation of charge-based spin drift enhancement compared to diffusion-only configurations. We investigate the modulation …

Reining In Plasticulture From Land To Sea: Pacific Northwest (Usa) Perspectives On Agriculture And Aquaculture, Susanne M. Brander, Gail A. Langellotto, Minal T. Mistry, Sebastian L. Singleton, Mackenna A. Hainey, Lauren M. Kashiwabara, Kelsey Arthur, Elise F. Granek, Kervelle Baird, Ricardo Palazuelos, Multiple Additional Authors

Environmental Science and Management Faculty Publications and Presentations

Plastic use in food production—known as plasticulture—has transformed agriculture and aquaculture globally. Plasticulture gained momentum in the mid-20th century with the development of novel plastic materials, and by 2009, U.S. farmers used over 200 million pounds of plastic films annually. Though plastics have increased yields and efficiency, they now pose environmental hazards through the release of microplastics (MPs) and chemicals. Despite extensive documentation of MPs in the environment, their role in U.S. food production and impacts on crop, livestock, and aquaculture health remain underexplored. In regions like the Pacific Northwest (PNW), with robust agricultural and aquaculture sectors, plastics from films, …

Systematics And Phylogeography Of Mundochthonius Chamberlin, 1929, In The Pacific Northwest (Chelicerata, Pseudoscorpiones), Amanda Rai Montoya-Cowan

Dissertations and Theses

Understanding the processes that drive genetic divergence and species formation is central to evolutionary biology. Invertebrates with low dispersal ability, such as pseudoscorpions, are especially prone to cryptic diversification due to their occupancy of niche microhabitats and sensitivity to landscape barriers. Despite their ecological roles as predators and bioindicators, pseudoscorpions remain one of the least studied arachnid groups, with limited taxonomic resolution and few integrative studies. This research focuses on the genus Mundochthonius in the Pacific Northwest, particularly M. pacificus, a morphologically conserved species whose true diversity and distribution remain poorly understood.

Field surveys guided by a GIS-based habitat …

Mechanistic Rationale For Toxic Aerosol Formation From Vaping And Dabbing With A Focus On Ketene Formation From Semi-Synthetic Cannabinoids, Kaelas Ryan Munger

Dissertations and Theses

Cannabis vaping is a relatively new route of administration that is increasingly common among youth and young adults. Cannabis vaping has been associated with cases of acute lung injury, especially among youth, and most often involves the heating and aerosolization of high-potency products having cannabinoid concentrations of ~ 50 % - 98 % w/w. Proponents argue that vaping is safer than smoking due to the characteristically lower temperatures and fewer plant materials. However, the extreme cannabinoid concentrations, along with non-natural formulations having undisclosed additives, require studies of the health effects of these products. Despite the popularity of cannabis concentrate vaping, …

Developing Workflows For Passive Acoustic Detection Of Bedload Transport, Quinn Morgan

Dissertations and Theses

Bedload transport is defined as the amount of sediment, including gravel and rocks, traveling down stream. Monitoring bedload transport is important for river safety, hydrological studies and conservation efforts. Existing methods of directly measuring bedload transport (or bedload flux) involve lowering a collection device into a river and measuring the sediment collected; which can be expensive and time consuming. Hydroacoustic sensors, such as hydrophones, have had success tracking bedload flux remotely. This works by measuring the relatively high frequency of sediment impacts to map onto total bedload transported. No perfected method for detection of sediment generated noise (SGN) currently exists. …

Barriers Beyond Bars: Examining Experiences Of Students With Criminal Records, Anakin Rivera Ramirez

Dissertations and Theses

As educational opportunities, particularly prison education programs, continue to expand for incarcerated individuals, this study, which included two participants, one formerly incarcerated and one who pleaded guilty to avoid incarceration, suggests that those who plead guilty to avoid prison may enter college without the structured reintegration resources available to their incarcerated peers. While substantial research has explored the school-to-prison pipeline phenomenon in K-12 settings, fewer studies have examined its impact on students with criminal records navigating higher education. Grounded in Critical Race Theory (CRT) in education, this study seeks to understand the experiences of carceral system-impacted students of color in …

Evaluation Of User Interactions And Preferences Of Shared Bicycle And Pedestrian Transit Platforms, Nathan Mcneil, Sirisha Kothuri, Jennifer Dill, Chris Monsere, Elizabeth Yates, Julia Plotts

Civil and Environmental Engineering Faculty Publications and Presentations

Shared bike and bus platforms have been deployed in an effort to minimize conflicts between bicycles and buses (and other motor vehicles) on streets with bike lanes and bus transit service. This paper assesses bicycle/micromobility user and pedestrian behavior in shared bicycle and transit platforms along a bus rapid transit corridor in Portland, OR. Research objectives include understanding interactions between these users and potential conflicts between people on foot (or wheelchair/mobility devices) who are waiting for, boarding, and/or alighting a bus and people on bicycles riding in the bike lane. The research also assessed how well the shared transit platforms …

Controlling The Curriculum: A Content Analysis Of Prageru's Children's Educational Material, Heather Katherine Costa

Dissertations and Theses

PragerU is a conservative media outlet founded by Dennis Prager in 2009 that aims to insert new conservative content into existing U.S. public school curricula. While conservative activist groups have attempted for decades to alter educational content and policy, PragerU is attempting to directly influence public school curricula by having their materials authorized for use in public schools.

This study utilizes qualitative content analysis to understand the meaning behind PragerU's content, using a sample of 39 videos, targeted at students in grades 6 and higher. The transcript data were analyzed to address two research questions: 1) What are the key …

Autistic individuals are disproportionately likely to experience suicidal thoughts, feelings, and actions. Addressing suicidality is also a high priority of autistic community members. The goal of this study was to understand broad influences on suicidality and suicide-prevention needs for the autistic community. Using a community-based participatory research approach, we conducted a reflective thematic analysis of qualitative interviews with 16 autistic adults, 8 family members, and 14 mental health providers. Themes summarizing influences on suicidality and suicide-prevention needs centered on three broad thematic concepts: (1) Pervasive negative societal attitudes and social experiences have a lasting impact on autistic people's feelings of …

School of Social Work Faculty Publications and Presentations

Residents and fellows in graduate medical education (GME) programs across the USA often complete training during childbearing years, presenting challenges for pregnant and parenting trainees balancing work and family. Institutional policies must better support these trainees. Previous studies show supported trainees experience reduced burnout, better health, and improved patient outcomes.

This study assessed the experiences and unmet needs of pregnant and parenting GME trainees and presents their recommendations for improved support.

Methods: Using a sequential explanatory mixed-methods design, we examined the unmet needs and challenges of pregnant and parenting trainees, and their recommendations for improvement. We distributed a survey to …

Clinic Vs. Daily Life Gait Characteristics In Patients With Spinocerebellar Ataxia, Vrutangkumar V. Shah, Daniel Muzyka, Adam Jagodinsky, Hannah Casey, James Mcnames, Mahmoud El-Gohary, Kristen Sowalsky, Delaram Safarpour, Patricia Carlson-Kuhta, Fay B. Horak, Christopher M. Gomez

Electrical and Computer Engineering Faculty Publications and Presentations

Background:

Recent findings suggest that a single gait assessment in a clinic may not reflect everyday mobility.ObjectiveWe compared gait measures that best differentiated individuals with spinocerebellar ataxia (SCA) from age-matched healthy controls (HC) during a supervised gait test in the clinic vs. a week of unsupervised gait during daily life.

Methods: Twenty-six individuals with SCA types 1, 2, 3, and 6, and 13 (HC) wore three Opal inertial sensors (on both feet and lower back) during a 2-minute walk in the clinic and for seven days in daily life. Seventeen gait measures were analyzed to investigate the group differences using …

A New Era Of Zines: Taking Lessons From The Past To Combat Intellectual And Political Fascism, Catherine Kane

Book Publishing Final Research Papers

Zines have long functioned as a way to circumvent the traditional gatekeepers of news, art, mainstream narratives, and publishing. They are largely non-commercial, and their emphasis is to put the means of production and distribution directly into the hands of the individual. Although their roots are in DIY, proletariat culture, they are now the subject of study in museums, libraries, and higher education, and have been co-opted by big brands, media outlets, and publishing houses—the institutions they originally sought to undermine.

In their most authentic form, zines have represented free thinking and speech, while giving individuals and communities a rallying …

“Migration Craziness!” Financial Turbulence And Transnational Families In Sri Lanka, Michele R. Gamburd

Anthropology Faculty Publications and Presentations

Why might three relatively well-off, middle-class, young adults from Sri Lanka chose to leave their parents and their village to emigrate to Australia and Italy? Why would these men and women give up promising careers and comfortable homes to start over elsewhere and endure the hardship of an immigrant’s deskilled and displaced life? To understand their decisions, I rely on anthropology’s holistic perspective to help me stitch together intimate details about family choices within a context of global economic structures and national politics. I have done ethnographic research in the village that I call “Naeaegama” since 1992. I have studied …

Estimating Historical Age-Sex Distributions Of A Tribal Population: A Case Study Of The Hopi, 1900 To 1940, David Swanson, Jeff Tayman

Publications, Reports and Presentations

Historical information on tribal populations in the United States is scattered and discontinuous. A significant part of the discontinuity is the gap between 1900 and 1970. This paper describes a process that may partially fill this gap by developing decennial age-sex data from 1900 to 1940. Where temporally consistent, we compare these estimates to those done by others. This work provides a point of departure for generating more demographic information about the Hopi from 1900 to 1940 and, ultimately, beyond 1970, a critical turning point regarding the increased availability of American Indian data from the U.S. Census Bureau. It also …

The End Of International Migration? The Case Of North America, David Swanson, Jeff Tayman

Publications, Reports and Presentations

Although there are exceptions (forced migration and retirement migration, for example), international migration is largely driven by people of working age. Population forecasts to the year 2100 show that the numbers of people of working age (20-64) will diminish in North America (Canada, Mexico, and the United States), and dramatically diminish among those of the younger working ages (20-34 and 35-44). Underlying this expectation is the fact that North America, like the world as a whole, will have completed the demographic transition or be very close to completing it within 75 years, which means this region of the world will …

Biofluid Biomarkers Aid In Diagnosing And Developing Improved Treatments For People With Alzheimer's Disease, Jonatan A. Lopez

University Honors Theses

Dementia is a disease in which daily life is disrupted by a loss of cognitive function. Late-onset Alzheimer's disease (AD) is the most common dementia that largely begins to affect individuals in their mid 60s or older. AD was selected as the focus of this paper because it is the most common form of dementia, accounting for 50-70% of dementia cases. A typical diagnostic approach used by physicians starts with a simple clinical test, the Mini-Mental State Examination (MMSE), when cognitive decline is suspected in a patient. Then if there is enough evidence to suggest AD, a physician would order …

"The Biggest Outing Of The Year": Hops, Harvest, And The Making Of Oregon's Largest Annual Gathering, 1880-1930, Asher Bernick-Roehr

University Honors Theses

When the end of August came around, all kinds of people started rolling into the little town of Independence, Oregon. Some walked, some came by train, others by wagon, and still others by ferry, motorboat, and canoe. There were Armenians, Swedes, Chinese, Japanese, Indians, Russians, Germans, and Indigenous peoples. There were those who were called fruit tramps, individuals and families who managed to bridge the vast distances across the West to harvest whichever crop needed hands. Entire families arrived, young and old, healthy and sick, with horses, mules, chickens and dogs in tow. Rich men came dressed as poor men …
