Social support has been identified as a critical factor in helping people navigate houselessness and will be explored in the current study. Specifically, the current study examines social support among populations with lived experience of houselessness as they navigate pathways through houselessness. The current study is situated within a broader study examining journeys through houselessness called the Pathways study, and it utilizes a subsample of individuals involved in the Pathways study. The Pathways study and the …

Disaster Justice: Queer And Disabled Mobilities And Infrastructures Of Care In The Pacific Northwest, Rachel Springer

Dissertations and Theses

This dissertation examines the social, political, and environmental pressures that drive LGBTQ+ migration to the Pacific Northwest and the social infrastructures people find on arrival. Drawing on thirty-four semi-structured interviews with LGBTQ+ adults who relocated between 2022 and 2025, it argues that these movements are best understood as responses to slow-onset disasters produced by the compounding interaction of legislative targeting and infrastructural violence.

State-level legislation targeting LGBTQ+ people—particularly transgender individuals—has fractured the geography of safety in the U.S., producing a landscape where civil rights, healthcare access, and everyday security vary dramatically across space. For those navigating these conditions at the …

Life Without Oxygen: Cellular Mechanisms Enabling Genome Maintenance And Proliferation In Cells From An Anoxia-Tolerant Vertebrate, Riley Asa Roth-Carter

Dissertations and Theses

When exposed to the complete loss of oxygen (anoxia) most organisms undergo rapid cellular deterioration driven by a range of metabolic dysfunctions associated with the loss of the terminal electron acceptor for aerobic respiration. This loss of ability to create and maintain necessary levels of cellular ATP through oxidative phosphorylation contributes to loss of membrane potentials, increase in the accumulation of acidic by-products of anaerobic metabolism, and a decrease in the ability to support other molecular processes that rely on a steady supply of ATP. While this extreme oxygen stress is lethal to a majority of vertebrate organisms there are …

Japanese Learners And Mixed-Speech Styles, Nana Kawada

Dissertations and Theses

This study explores to what extent Japanese as a Target Language (JTL, henceforth) learners use mixed-speech styles. "Mixed-speech styles" refers to the phenomenon that occurs when speakers shift speech styles during the course of an interaction. The three primary speech styles are (1) the desu/masu forms, which are generally considered formal speech-level markers, (2) the non-desu/masu forms, considered informal speech-level markers, and (3) the Chūto shūryō-gata, which I translate to unfinished utterances that do not contain a clear style-marker.

The studies examined naturally occurring conversation point out that Japanese speakers often strategically manipulate and mix these speech styles …

Modeling Turbulent Accretion Flows Around Black Holes: Azimuthal Flux Derivative Density Curves In 3d Mhd Simulations, Sasmitha Purushothaman, Matthew D. Duez, Pavan Chawhan

University Honors Theses

When modeling two-dimensional axisymmetric accretion disks around Kerr black holes, setting the azimuthal terms of the MHD equations to zero causes the loss of turbulence and dynamo effects. In this paper, we use three-dimensional models to identify the turbulence that arises from azimuthal flux derivatives (AFDs) and create probability density functions to characterize them. We establish a pipeline for calculating the AFDs, creating a distribution, and normalizing it. Then, we plot the dependence of the conditional probability of the AFDs on density, magnetic field strength, and velocity for the continuity and magnetic induction equations. Future research can take this information …

Homelessness And Business: Perception, Affect And Opportunity, Asatur Nor-Ashkarian

University Honors Theses

This thesis examines the relationship between business owners and individuals experiencing homelessness within urban commercial districts in the United States, arguing that the dynamic is shaped primarily by spatial concentration, uneven power structures, economic pressure, and public framing rather than simple conflict between competing interests. Drawing on stakeholder analysis, business perception surveys, a mixed-methods study, and an original content analysis of 50 news articles spanning 23 states, this thesis identifies a consistent pattern: business owners broadly perceive homeless presence as negatively impacting safety, cleanliness, and consumer behavior. Local news media reinforces those perceptions through predominantly negative framing of homeless individuals. …

Comparing The Sensitivity And Degree Of Boolean Functions Via The Hypercube, Anne-Caroline Rupp

University Honors Theses

This thesis studies three complexity measures of total Boolean functions f:{0,1}ⁿ → {0,1}: maximum sensitivity s(f), polynomial degree deg(f), and spectral sensitivity λ(f), where λ(f) is defined as the spectral norm of the adjacency matrix of the sensitivity graph. Building on the results of Aaronson et al., we examine the inequality chain √s(f) ≤ λ(f) ≤ deg(f) and investigate whether all three quantities can be simultaneously equal.

The first part of the thesis reverse engineers the equality cases of the two known inequalities to isolate necessary extremal conditions on both the Fourier structure of f and the local geometry …

Radical Social Work In The United States: An Integrative Literature Review, Anastasia Miller

University Honors Theses

Scholars have noted that social work in the United States is particularly dependent on, and tied to, the government. While frameworks that are popular in the U.S. explicitly provide social support, they also implicitly maintain social order. Thus, social work in the U.S. may provide immediate, short-term relief, but as a result of government-imposed limitations, dominant social work frameworks do not work towards the ultimate liberation of humanity. Radical social work methods both challenge and liberate service users, along with those who deliver them.  Existing scholarship has examined the development and implementation of radical social work across the globe– especially …

Exploring The Durability Of Marine Picocyanobacterial Microcolonies, Erik Swanson

University Honors Theses

Picocyanobacteria of the genus Synechococcus are widespread aquatic photoautotrophs that play essential roles in primary production and carbon cycling. Some Synechococcus strains form multicellular microcolonies, but the mechanisms of cell-to-cell attachments and structural durability of these microcolonies remain poorly understood. This research investigated the physical durability of microcolonies in two marine Synechococcus strains (CC9605 and CC9311) using physical disruption treatments. Cultures were subjected to vortexing and sonication treatments, and populations of single cells and microcolonies were quantified using flow cytometry based on differences in measures of size. Results indicated that strain CC9605 showed no significant treatment effect, whereas CC9311 displayed …

Psychological Architecture: Evaluating The "Greenhouse Model" As A Structural Standard For Lgbtq+ Well-Being, Ava Lee

University Honors Theses

Traditional LGBTQ+ mental health frameworks often conceptualize psychological safety as a matter of individual endurance. This paper critiques this focus on adaptive resilience, which systematically shifts responsibility from institutions to individuals. To counter this, the study introduces "Psychological Architecture," a framework viewing social environments as constructed infrastructures that can either support or undermine queer well-being. The model contrasts performative "Glasshouses," which prioritize visibility over safety, with engineered "Greenhouses" that nurture sustainable safety through three sequential pillars: Authentic Representation (walls), Emotional Validation (insulation), and Vocal Activism (ventilation).

Grounded in the findings of a 2024 qualitative pilot study of a queer roller …

Not Everyone Gets A Tree: Housing Values, Street Trees, And Equity In Portland, Matthew Moller

University Honors Theses

Street trees are positively associated with Portland home sale prices, but exposure and capitalization are uneven by race/ethnic neighborhood context. Urban trees are ecological assets, but their economic and equity implications remain uneven. This thesis examines street-tree exposure and 2023 residential sale prices in Portland, Oregon (n = 6,414) using a mixed-methodology hedonic design. Ordinary least squares models measure inventoried street-tree counts within 20m, 50m, and 100m buffers together with structural controls and census-block racial and ethnic context. Trees are positively and significantly associated with logged prices at all radii, with scale-sensitive magnitudes and modestly better fit as wider buffers. …

The U.S. Shopping Mall: Opportunities For Preservation And Transformation Through Adaptive Reuse, Sophia Janzen

University Honors Theses

The U.S. shopping mall, once an integral part of suburban living and community, has slowly disappeared from cities nationwide. What used to be thousands of malls sprinkled throughout America in the 20th century is estimated to be 900 by 2028. A mall's programming of the past is lacking a place in the future, but their architecture leaves a desolate structure in the midst of our cities. Through adaptive reuse, the intentional redevelopment of a preexisting structure, how can malls be thoughtfully revitalized and given a greater purpose within their surroundings?

This research analyzes successful adaptive reuse strategies implemented in few …

The Effects Of Adverse Childhood Experiences On Female College Students' Social Emotional Development: Is Flourishing Possible?, Kaylee Kirkwood

University Honors Theses

Adverse childhood experiences are events of trauma and abuse that occur prior to age eighteen. High rates of sexual violence against girls and female undergraduate students inspired this study to explore how trauma may impact development and overall college experience. This thesis employed a small exploratory pilot study to investigate childhood trauma and social-emotional development among a small sample of female college students (ages 18-25; n = 41). Participants recruited through the Prolific Database completed an online Qualtrics survey consisting of screeners, demographic questions, measures of trauma history and emotional functioning, and optional open-ended experience-based questions. Measures were guided by …

A Twilight World Of Unspeakable Horror: Lesbian Camp And The Vampire Lovers (1970), Mirielle Lemay

University Honors Theses

From the late 1960s through the early 1970s, a wave of lesbian vampire themed exploitation films proliferated through UK, US, and Western European cinemas. In critical literature on this subgenre, camp reading is often dismissed, unacknowledged, or understood as circumscribed by authorial intent and/or intended audience. With this alternating lack of attention to and dismissal of camp, the interpretive agency of the queer spectator is constrained, their spectatorship implicitly subordinated to that of the "conventional" horror audience—the voyeuristic-sadistic male spectator. Through a reading of The Vampire Lovers, a 1970 British production from Hammer Studios, I seek to explore how …

Disability Experiences Of University Students: An Interview Study, Cece Austin

Using a qualitative research design, semi-structured interviews were conducted with students who identify as disabled or having disabilities in order to explore impacts of disability on their lives, with a focus on experiences navigating academic environments and accessing accommodations. Findings revealed two recurring themes: 1) the importance of both registered accommodations and accessibility efforts from faculty, and 2) difficulties with accommodations, internalized ableism, and disclosure. This research contributes to broader discussions on disability, inclusion, and educational equity by highlighting the lived experiences of students with disabilities …

Holding Pattern: The Making Of An Ep, On Intuition, And Form Becoming The Content, Oscar Larson Phillips

University Honors Theses

This craft essay traces the making of "Holding Pattern," a three-song EP representing the culmination of five years of development in composition, production, lyric writing, and sound engineering. Each song addresses its own distinct emotional territory: the tension between confidence and self-doubt, resistance to creative conformity, and the experience of emotional dissociation. Together they form a single arc: reaching out, holding your ground, and surviving it. This essay moves through each song, examining how production decisions, lyrical construction, and the recording process each served the content of the work. Working intuitively across composition, sampling, collaboration, and recording, what only became …

Applications Of Prior And Novel Computational Tools In Mental Health Treatment, And Their Potential To Uncover The Explanatory Gap, Ambika Vyas

University Honors Theses

The explanatory gap is a widely discussed concept in scientific and philosophical literature. In neuroscience, the solution to the explanatory gap is highly sought out, but the general consensus is that it is unsolvable. Numerous articles discuss the explanatory gap alongside computational tools and how these tools could aid neuroscientists in uncovering the mental health explanatory gap. However, significant developments in machine learning have been made since 2020, coinciding with the rise in Large Language Models (LLMs). This thesis is a literature review on computational methods, tools, and devices developed and utilized by researchers to improve how mental health disorders …

Facilitators And Barriers That Exist For Patients Receiving Dental Care In Rural Communities, Monse Sandoval Brumbaugh

University Honors Theses

Rising healthcare costs and limited access to care have exacerbated the shortage of healthcare providers. Although multiple factors contribute to a clinician’s preference for practicing in rural areas, the imbalance created leads to rural communities with significantly reduced access to essential services, particularly dental care. The disparity between urban and rural healthcare is a well-documented global problem, but it remains a pressing issue in the United States, particularly in Oregon. The Full Time Equivalents (FTE) count of full-time practicing dentists in rural regions is significantly lower than in urban areas. Statewide, there are about 0.48 dentists per 1,000 residents. However, …

Gps Tracking Smart Dash Cam Capstone Review, Simrah Saleem

University Honors Theses

This thesis details our design, implementation, and collaborative development of an intelligent vehicle logging system built on a Raspberry Pi 5. Unlike standard consumer dash cams that act as closed "black boxes," our system uses a dual-camera stereo vision setup integrated with centimeter-level accuracy. While we successfully built a functional Proof of Concept capable of event-triggered recording, dual-monitor visualization, and smart detection and recognition, this paper focuses on our engineering journey and the real-world challenges we faced.

School Counseling With Indigenous Students In Rural America: The Role Of A Counselor In Supporting An Indigenous Pedagogy Based Curriculum, Donovan Greene

University Honors Theses

Indigenous students are a huge population that are not fully supported by the school psychology field. This is primarily due to cognitive imperialism and the focus on a Western monoculture in education. This has led school psychologists and counselors feeling underprepared and lacking the tools to work with Indigenous students and as a result these  students are harmed academically and in terms of their mental wellness. This essay opens with a literature review of scholarship on school counselors working with Indigenous students. To improve relations, I suggest implementing more culturally focused interventions. Unfortunately there is a lack of research on …

Hillslope Aspect And Other Potential Controlling Factors On The Spacing Of Periglacial Stone Stripes In Se Oregon, Blue Hansen

University Honors Theses

Stone stripes are a type of patterned landscape that can be polygenetic in origin, but in the High Lava Plains province are interpreted to be relict periglacial features based on similarities to active stone stripe formation in current periglacial settings. Periglacial stone stripes are hypothesized to form via frost process, including ice-driven cracking and soil heave which is dependent on temperature, long-term differences in temperature may contribute to differences in stone stripe patterns or density. Stone stripes in Oregon and Idaho have previously been studied using field techniques, but there is room for reexamination of temperature controls on hillslope density …
