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 …

Rarely Asked: The Systemic Failure To Support The Mental Health Of Caregivers Of Medically Complex Children, Morgan Motsinger

University Honors Theses

Approximately one in four households in the United States cares for a child with special healthcare needs, yet the mental health of the caregivers providing that care is rarely addressed by the medical, faith, community, and social systems around them. This thesis examines the systemic gaps in mental health support for caregivers of children with life-limiting or medically complex diagnoses through a review of existing literature and an original mixed-method survey of 58 caregivers. Findings indicate that 50% of caregivers received no mental health support from their child's medical team at any point. Every respondent reported at least one clinically …

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 …

Social Determinants As A Predictor For Heart Disease Mortality: Oregon Regional Study, Jewel Jones

University Honors Theses

The study examined the association between selected social determinants of health and heart disease mortality across geographic regions in Oregon. Using a regional analysis design, county-level population and mortality data were grouped into nine geographic regions to evaluate patterns of cardiovascular disease burden across the state. Social determinant variables were obtained from publicly available U.S. Census Bureau datasets and included poverty, crowding among households, single-parent households, lack of broadband internet subscription, housing cost burden, high school diploma attainment, and unemployment.

Heart disease mortality counts per 100,000 population were derived from official birth and death certificate records. Statistical analyses were conducted …

Developing A High-Resolution Off-Axis Common-Mode Digital Holographic Microscope, Lucy Cook

University Honors Theses

Off-axis digital holographic microscopy (DHM) is a powerful tool for 3D, non-invasive live-cell tracking without moving parts. However, traditional setups face an inherent dilemma: split-path interferometers offer high spatial resolution but poor temporal stability, while more stable common-mode configurations are historically limited to lower numerical aperture (NA) regimes. This thesis bridges that gap by scaling a common-mode DHM architecture into a high-resolution benchtop instrument featuring NA = 0.65 objectives, paired with a high-power 520 nm laser source to combat transmission losses and sustain imaging frame rates across an expanded optical footprint. We map the multi-variable design space required to satisfy …

Looking Upwards And Out: Comparing Buddhist And Humanist Frameworks For Enlightenment, Mason Mckinney-Best

University Honors Theses

During the Zen Boom of the 1950's, Psychologists, Philosophers, and other western thinkers were exposed to Zen Buddhism and began to harness some of the principles for use in Psychology. In the last 3 decades, Psychologists have renewed their interest in Buddhism, especially as "fourth wave" cultural competence has become an important part of Psychological practice. While work has been done in developing clinical applications of Buddhist practices, more could be found in Buddhism for the person who wishes to become more healthy.

Within Psychology, one figure had exactly that objective: Abraham Maslow. His work on Self-Actualization has been …

The Social Construction Of Risk: How Media Socially Constructs Risk Perceptions Surrounding School Shootings Among College Students, Natalie Jobe

University Honors Theses

Although school shootings are statistically rare events, public fear surrounding them has continuously increased across the United States. This thesis explored how college students perceive the risk of school shootings despite the relatively low probability of experiencing these violent events, with particular attention to the role of media framing, sensationalized reporting, and repeated exposure to violent social and digital media. In order to examine how media framing, social and digital media exposure, as well as ongoing encounters with violent content affect risk perception, this research conducted six interviews with traditionally aged college students from Portland State University regarding their experiences …

Grief, Silence, And Surveillance In Academic Settings, Rakhi Grey

University Honors Theses

This study examines how grief is silenced, monitored, and regulated within higher education settings. Drawing on semi-structured interviews with undergraduate students who experienced the death of someone significant, this study explores how institutional expectations surrounding productivity, professionalism, emotional control, and academic functioning shape grief disclosure, emotional expression, and help-seeking behaviors. Using a critical theoretical framework informed by concepts of disenfranchised grief, legitimacy hierarchies, and surveillance, findings suggest that grief within higher education is not simply individually experienced, but socially and institutionally regulated. Participants described academic environments that often left little space for ongoing grief, requiring students to compartmentalize emotional distress, …

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 …

However, it became clear that the team, leader included, had a gap in knowledge and skills to be successful, as well as a lack of experience in team …

The Cleansing Effect Of Technological Investment: An Empirical Analysis Of Episodic Labor Market Polarization (2000–2010), Adam Murphy

University Honors Theses

This paper investigates the episodic nature of labor market polarization in the United States between 2000 and 2010. While the Skill-Biased Technological Change (SBTC) framework may have successfully explained the rise of inequality in the 1980s, it struggled to account for the wage stagnation and hollowing out of the middle class that followed in the 1990s and 2000s. Utilizing Task-Biased Technological Change (TBTC) as a primary lens, this study examines how the codification of routine tasks allowed for the widespread substitution of middle-skill labor by technological capital. By synthesizing IPUMS-CPS occupational data with Bureau of Economic Analysis (BEA) investment statistics, …

Fundamentalist Disorientations For Queer Subjects: Narrative And Theory, Betty Canoso

University Honors Theses

This thesis examines disorientation experienced by queer people who were raised in high-cost fundamentalist Christianity–people like me. Disorientation is a philosophical concept useful for examining specific intersections of human experience, like queerness and fundamentalism. Philosophers such as Sara Ahmed (2006) and Ami Harbin (2016) have been exploring the intersection of queerness and disorientation. Psychologists, sociologists and researchers from other disciplines are analyzing the interrelatedness of queerness and religion, and disaffiliation and deconversion from high-cost or high-control religions is another ongoing area of interest. Yet, despite widespread interest in these concepts, few have looked at instances of disorientation as they pertain …

Who Keeps Us Safe? Youth Resistance And Security Regimes At The Neoliberal University, Arwen Hansell

University Honors Theses

In a political climate shaped by surveillance, labor precarity, policing, and immigration enforcement, questions of (in)security increasingly organize everyday life. Governments justify security measures through the language of public safety, even as many people experience insecurity surrounding housing, healthcare, employment, and the future itself. Although critical security studies have examined policing, militarism, and surveillance extensively, youth are often overlooked as political actors despite their central role in social movements. This study addresses that gap by focusing on student labor organizers and activists navigating (in)security. Using collaborative ethnography, I conducted fieldwork at protests, labor organizing meetings, workshops, and demonstrations connected to …

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. …

Reconfiguring Dependency: China's Belt And Road Initiative And Development In Ethiopia And Nigeria, Alexander Freund

University Honors Theses

This thesis examines China's Belt and Road Initiative (BRI) in Africa through the frameworks of dependency theory, postcolonial theory, and neo-colonialism. As China's global economic influence has expanded throughout the twenty-first century, the BRI has emerged as a major source of infrastructure financing and development across the Global South, particularly in Africa. While critics frequently portray the initiative as a form of "debt-trap diplomacy," supporters argue that Chinese investment offers an alternative to the neoliberal conditionality historically associated with Western-led International Financial Institutions (IFIs) such as the International Monetary Fund and World Bank. This study addresses two central research questions: …

The Scars Of Renewal: How The Legacy Of Urban Renewal Informs Community Response To Gentrification In San Francisco's Fillmore District, Christopher Hayes

University Honors Theses

What is the disconnect between what the people living in the city say that they want, what the politicians say they're doing to address it, and where does that disconnect come from? Using a case study of San Francisco's Fillmore District, this study investigated discourses of gentrification in media coverage. As a historically Black neighborhood that was severely disrupted by post-World War II Urban Renewal programs, the Fillmore's story mirrors that of many other neighborhoods in the United States. Today, there are heated debates about how to move forward with development given this history and the declining numbers of African …

University Honors Theses

The study aims to explore grief experiences of college students in relation to world issues, namely ecological and political concerns and ways of making/finding meaning, hope, and purpose. To address a gap in research on manifestations of combined and multifaceted world grief experiences, qualitative research was conducted in the form of semi-structured interviews with 6 different college students. Common themes arose from the interviewees' grief experiences including hopelessness, overwhelm, anger, and changed future planning. Additionally, participants shared their experience finding community, engaging in creative pursuits, and taking action against oppressive systems in order to experience hope and purpose individually and …

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 …

"I Still Care About Her": Ambiguous Loss And Social Death In Substance-Affected Relationships, Margaret M. King

University Honors Theses

Substance use creates a ripple effect, affecting the individual as well as their family members. The struggles associated with problematic substance use result in feelings of ambiguous loss towards the substance using individual, a type of loss in which a person is still living but either psychologically or physically unavailable. This research explores the experiences of ambiguous loss in college students with loved ones struggling with substance use, examining how they are thrust into caregiving roles, experience support, and find meaning within their loss. Seven semi-structured interviews were held with adult college students who identified as having a loved-one struggling …

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. Using an Agile framework, we split into three specialized sub-teams to handle hardware, database, and interface design in parallel. This structure created unique …

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, …

The Power Of Perception: Latine Threat Narratives And Immigration Control In The United States, Nina Gallo

University Honors Theses

Despite America's rich history as a self-proclaimed "nation of immigrants," immigration policy in the United States has functioned as a tool of social control designed to systematically exclude and restrict groups of people that pose a perceived threat to national identity and safety. This perceived threat has effectively been communicated through harmful narratives that stratify immigrant communities from the rest of society. Through this framing, support for punitive immigration policies thrives. Currently, Latine immigrants and their families have been the target of discriminatory immigration policies and enforcement tactics. No work to date has synthesized the current state of the immigration …

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 …

Jazz V. Law: An Overview Of Copyright Law For Jazz Musicians, Trevor Thompson

University Honors Theses

The United States copyright system has become increasingly complicated and has developed a bias toward written, notated mediums over performance mediums. This bias can be traced from the Statute of Anne through the modern system under the Copyright Act of 1976, and it directly affects jazz musicians' ability to comply with copyright laws and properly receive royalties for their work. This study traces the evolution of copyright law from 1710 to the present, noting important cases such as White-Smith Music Pub. Co. v. Apollo Co., McIntyre v. Double-A Music Corporation, and Tempo Music, Inc. v. Famous Music Corp. …

Geographic And Systemic Disparities In Maternal Health: A Systems Analysis Of Prenatal Care Access Across Rural Oregon, Cecelia Petrik

University Honors Theses

Objectives: In Oregon, 51% of hospitals providing labor and delivery services are located in rural areas. Consolidation of these hospitals and provider shortages has created severe geographic and systemic disparities in maternal healthcare. This thesis explores how geographic isolation and inadequate prenatal care access contribute to widening disparities in severe maternal morbidity (SMM) and mortality across Oregon's rural and frontier counties.

Methods: This study utilizes data from the Oregon Health Authority (OHA) Center for Health Statistics (2024) and analyzes spatial correlations across all 36 Oregon counties. A bivariate choropleth map was constructed to examine the structural intersection between health infrastructure …

Shallow-Marine Crinoid Genera May Have Been More Resilient Across Permian Extinction Events In Terms Of Richness Than Deep-Marine Crinoid Genera, Amelia C. Kolstad

University Honors Theses

Throughout the Phanerozoic, one of the most successful phyla of marine invertebrates has been Echinodermata. Echinodermata was particularly successful throughout the Paleozoic, with class Crinoidea making up a majority of occurrences. The proportion of echinoderm occurrences that are crinoids declined massively at the end of the Permian and continued to decrease into modern day, never fully recovering. One of the factors thought to have been so important for crinoid success in the Paleozoic and their decreasing success throughout geologic time has been their propensity for success in shallow-marine environments, though crinoids also exist within deep-marine environments. This study seeks to …

The Magic Wand: The Transformation Of Literary Journals And The Middle Class In Early Nineteenth-Century Germany, Charlotte Bayer

University Honors Theses

Compared to other products of German Romanticism, scholarship has almost entirely overlooked the magazine Wünschelruthe (1818). No in-depth, original research has been made on the magazine since 1929. Investigations into the Wünschelruthe have only been within the frame of its connection to more influential works and authors within the German canon or as digression in biographies on its main contributors, and these writings usually neglect the actual content in the magazine. From a catalogue of dozens of literary magazines produced in Germany during the late Enlightenment and Romantic eras, the Wünschelruthe is also one of a select few (if not …

"Address It Or Suppress It": What We Can Learn About Rpf From Celebrity Responses, Z Maloney-Dunn

University Honors Theses

In a growing culture of parasociality, ways of engaging with celebrities are constantly changing. RPF (Real Person Fiction) is an often controversial subgenre of fanfiction written about real people. This thesis examines how celebrities respond to RPF written about them, using two case studies: the pairs of Dan Howell and Phil Lester as well as Greg Davies and Alex Horne. Both case studies have reacted positively to RPF, but have very different relationships with their audience and ways of responding to them. Through an analysis of various statements made by the subjects over the years, this thesis seeks to gain …
