Moving Beyond Traditional Cost Containment For Glp-1 Coverage Within Oregon's Proposed Universal Health Plan, Manoj Rajesh

University Honors Theses

In 2022, Oregon voters passed Measure 111, constitutionally mandating access to affordable health care. As the Universal Health Plan Governance Board (UHPGB) designs the state's proposed single-payer system, it faces an unprecedented financial vulnerability: the clinical demand for GLP-1 receptor agonists. These high-cost, indefinite-use medications for obesity and metabolic syndrome threaten to overwhelm fixed public budgets. Historically, both the Oregon Health Plan's Medicaid framework and commercial private insurers have relied on static cost-containment models—categorical exclusions, step therapy, and aggressive utilization management—that achieve short-term fiscal solvency at the expense of comprehensive preventative care. This thesis argues that to fulfill the mandate …

The Voice As The Ultimate Microtonal Instrument, Catherine Terrell

University Honors Theses

I wrote several songs in a non-standard tuning system, 19-equal temperament. I define and distinguish 19-equal temperament and 12-equal temperament, then explore why I decided to write in this tuning system. I argue that intonation is a tool composers can implement along with more common musical devices. After describing the methods I used to create this music, I detail how I taught performers to sing it. I then describe and analyze the several works of music I created. Through the compositional process, I found tuning to be a very effective means in expressing musical and poetic ideas.

Intersectionality And Insurgent Citizenship: Women Of Color Feminism In 1970s New York City, Genevieve Bonner Davis

Dissertations and Theses

Not since the phrase "Ain't I a Woman" has African American women's intellectual leadership and insight been as visible and influential as the contemporary concept of intersectionality. Like Sojourner Truth's iconic intellectual intervention in the anti-slavery movement, intersectionality has experienced a similar trajectory of dissolution, distortion, appropriation, and popularization. Since its articulation by Black legal scholar Kimberlé Crenshaw in 1989, intersectionality theory has had a bumpy road to its buzzy, if controversial, status in the firmament of twenty-first-century political thought.

This thesis traces the origins of intersectionality theory through three distinct but intertwined phases. Phase one is the genealogy of …

The Lion's Share: The Secret Land Grab Of Drake's Circumnavigation, Melissa Cole Darby

Anthropology Faculty Publications and Presentations

Francis Drake’s journey around the world between 1577 and 1580 is renowned as one of the most famous voyages in history. The circumnavigation was a great achievement for England, but the official story Queen Elizabeth and her Privy Council maintained for nine years was that Drake was a pirate, and that the treasure he captured on the voyage would be returned to Spain. Upon his return, information about the voyage and his route were suppressed and the crew was sworn to secrecy: they were not to reveal where they travelled on ‘pain of death’. Here I present the case that …

Toward Contextual Adaptation And Knowledge Grounding In Large Language Models, Yufei Tao

Dissertations and Theses

Large language models (LLMs) are now expected to adapt to context in ways that are both socially appropriate and informationally faithful. This dissertation argues that contextual adaptation and contextual grounding are the unifying problems behind that expectation: models must adjust to interactional settings such as role-play while also grounding their outputs in the information supplied at inference time. Across four studies, the dissertation examines how LLMs respond to social cues, how they balance contextual and parametric knowledge, how multilingual long-context settings reveal grounding failures, and how decode-time control can improve reliability.

The first study analyzes the ChatGPT Role-play Dataset (CRD) …

Psychosocial Risk Factors And Recidivism Among Violent Offenders, Abbey Elizabeth Burgess

Dissertations and Theses

This study examined whether changes in LS/CMI domain scores between prison intake and release were associated with three-year recidivism among violent offenders following their release from custody. While the Risk-Need-Responsivity (RNR) framework emphasizes the importance of targeting dynamic criminogenic needs to reduce reoffending, relatively little research has assessed whether changes in domain-level risk factors translate into improved outcomes over time. Using administrative data from a state correctional system, this study analyzed domain-level changes in LS/CMI scores and their relationship to rearrest, while controlling for demographic characteristics, criminal history, and institutional factors. Results indicated that changes in most LS/CMI domains were …

¡Estamos Aqui!: The Underrepresentation Of Latinos In Professional Sports And Sports Media, Antonio Hernandez

University Honors Theses

The Latino population has had a long and complicated history within the United States. Since the turn of the 21st century, Latinos continue to become the largest minority group within the country. As the Latino population continues to rise, other industries have failed to properly represent the community. Within the world of professional sports, Latinos continue to be grossly underrepresented, with professional athletes from Latino backgrounds representing less than 6% of all professional athletes across all disciplines. This number is just under ¼ of the total percentage of Latinos within the United States. With Latino's influence of other cultural phenomena …

The Educational Gender Gap Explored Through The Lens Of Hegemonic Masculinity, Marcell V. Csikos

University Honors Theses

Women's college attendance skyrocketed with the passing of Title IX, and by the eighties, college campuses featured men and women at an even fifty-fifty split. Today, women make up over fifty-seven percent of college students. It is not a new phenomenon, studies and surveys have shown that women are doing better at school for decades, but they rarely tie men's underperformance to the concept of masculinity. The study of hegemonic masculinity is an overarching theory that looks at the values, rules, and dynamics that men have to follow in order to keep their social status. This literature review uses said …

A Qualitative Study Into The Impact Of Sweeps On Homeless-Serving Mutual Aid Groups In Portland, Or, Clover Javurek-Humig

Dissertations and Theses

Sweeps and land use enforcement are among the most persistent issues impacting unhoused communities. Mutual aid groups in Portland network with unhoused people regularly to mitigate the impacts of sweeps, provide direct aid, and build social capital among encampments. This study aims to understand the impact of policing and sweeps on mutual aid groups working with unhoused communities in Portland, OR. I conducted 18 interviews with mutual aid organizers and 8 months of fieldwork with mutual aid groups in Portland, OR in the years of 2025–2026. Transcripts were analyzed using a general inductive approach. This study finds that 1) Mutual …

Shoplifting: Analyzing Spatial And Temporal Patterns, Elizabeth Petrenko

Dissertations and Theses

Shoplifting has contributed to significant losses in Oregon, reaching nearly $956 million in 2022. While overall property crime in Portland, Oregon, dropped between 2023 and 2024, reported shoplifting incidents increased by 50.0%. In Oregon, stealing property worth $100 or less is third-degree theft and a Class C misdemeanor. Second-degree theft involving stealing property between $100 and $1,000 is a Class A misdemeanor. Although often classified as petty or minor theft, shoplifting imposes strain on retailers, consumers, and communities, which raises questions about the spatial and temporal distribution of this crime. This study uses Portland Police Bureau (PPB) offense data to …

Justice By Geography: District-Level Variation In Pretrial Release Outcomes Across Oregon, Ethan Loomis

Dissertations and Theses

AbstractOregon’s pretrial system operates under a common statewide legal framework, yet detention and release outcomes do not appear fully consistent across jurisdictions. Earlier research on pretrial decision-making has largely focused on judicial discretion, individual-level legal factors, and the use of risk assessment tools, while giving less attention to the district-level environments in which those decisions are made. This study examines whether variation in institutional capacity, political context, demographic composition, and socioeconomic conditions corresponds with differences in pretrial outcomes across Oregon’s circuit court districts.

The study draws from focal concerns theory, racial threat perspectives, and organizational approaches to court decision-making. Rather …

Arylation Of Nitrogen, Oxygen And Carbon Nucleophiles By Aryl(Tmp)Iodonium Salts, Joseph Jordan Hatton

Dissertations and Theses

Substituted aromatic rings are present in industry in a plethora of organic molecules such as pharmaceuticals, agrochemicals, materials and beyond. Therefore, methods for broadly installing aryl rings into other compounds to create substituted aromatic rings are valuable to many organic chemists. Historically these transformations are achieved through methods such as nucleophilic aromatic substitution and metal catalyzed cross-coupling. Nucleophilic aromatic substitution is a user-friendly method in this space but is limited by reliance on specific electronics. Metal catalyzed cross-coupling reduced the dependence on electronics in this space, but metals are generally unattractive reagents due to high costs, toxicity and challenges with …

Improving Explainability And Interpretability Of Neural Networks Via Hyperparameter-Extended Influence Functions, William Breslin

Dissertations and Theses

Understanding how model predictions and training outcomes vary with changes in data, features, and modeling choices is central to explainable artificial intelligence. This dissertation introduces a unified framework for explainability by generalizing classical influence functions to encompass user-defined hyperparameters embedded in the training loss, model architecture, or data representation. By extending influence functions in this way, the framework broadens their applicability and integrates multiple explainability techniques into a single, coherent approach. It provides a common mathematical foundation linking data impact, feature importance, and model design analysis, and supports a broad class of additional explainability analyses beyond these settings. The demonstrated …

Design And Implementation Of Error Estimators For Finite Element Eigenvalue Problems, Gabriel Esteban Pinochet Soto

Dissertations and Theses

We present three publications, all encompassed under the umbrella of a posteriori error estimation theory for eigenvalue problems for finite element discretizations. The central objective of the research is the development of a general framework for the study of reliable estimation of eigenvalues and eigenspaces. We introduce applications to problems of theoretical interest as well as problems arising in real-life scenarios, such as optical fibers. The first paper focuses on the implementation of a dual-weighted residual error estimator for a nonselfadjoint eigenvalue problems arising from the study of leaky modes in optical fibers---Maxwell's equations, Perfectly Matched Layers, and a conforming …

Disparities Between Rural And Urban Patients With Epilepsy In Oregon From Time Of Seizure Onset To Genetic Testing And Surgical Treatment, Bahar Madani

University Honors Theses

Drug-resistant epilepsy (DRE) is associated with significant morbidity and worsened outcomes when access to specialized epilepsy care is delayed. Rural populations may face additional barriers to neurological evaluation, genetic testing, and epilepsy surgery due to geographic and healthcare access limitations. This retrospective cohort study evaluated disparities in epilepsy care timelines among rural and urban patients treated at Oregon Health & Science University (OHSU), one of Oregon's two Level 4 epilepsy centers. Electronic health record data were reviewed for 110 patients, including 80 urban and 30 rural patients. Variables included age at seizure onset, age at genetic testing, age at epilepsy …

Local And Indigenous Knowledge, Innovation, And Sustainable Development: Creating Sustainable Futures Amidst Crisis Conditions At The Community Level, Carlos Andrés Arias

Dissertations and Theses

In 1987, the Brundtland Commission's Our Common Future (1987) made clear the need to reject longstanding development processes and focus on sustainable development. The Commission stressed that actual sustainable development integrates three elements: social development, economic development, and environmental protection. Though developed nations have achieved economic growth through conventional and extractive development practices, these practices have intensified natural disasters driven by climate change, increased food insecurity, and deepened poverty. This has acutely impacted Indigenous and local communities, many of whom face crisis conditions, such as war, terrorism, civil disorder, and their aftermath. Even so, many of these communities successfully implement …

Haapxtàm Ka'Ál Yimisapʰíkʰ We Dream For Our Children Indigenous Pedagogies In Early Childhood Education: Survivance, Truth Telling, And Healing On Native Land, Sara Anne Koyano

Dissertations and Theses

Since Time Immemorial, Indigenous Peoples have lived, learned, and thrived on this continent, exercising their inherent sovereignty as Original Peoples and passing down Indigenous ways of knowing, being, and learning across generations. US settler colonial violence and assimilation policies have had historical and contemporary detrimental impacts on Native children, families, and communities by attempting to disrupt the intergenerational transmission of Indigenous knowledges. Consequently, many young Native children in Oregon do not have access to educational opportunities that value, honor, and affirm their Indigenous identities and cultures, nor do they see themselves reflected in their classrooms and curricula. Furthermore, in 2019, …

Heat Pump Water Heater Cta-2045 Implementation Guidance For Maximizing Demand Response Impact, Dana Kahiwahiwa Paresa

Dissertations and Theses

Residential flexible loads, such as heat pump water heaters, have great potential for grid reliability services; however, their effectiveness depends on reliable performance in response to coordinated grid service requests. While the ANSI/CTA-2045-B protocol standardizes communication, it does not mandate specific functional behaviors, creating a mismatch in which the device may comply with the communication protocol but fail to meet performance expectations. This manuscript demonstrates the need for a ANSI/CTA-2045-B implementation guide by quantifying these discrepancies through gray-box conformance testing of market-available units followed by large-scale simulations.

Field testing results revealed a significant conformance gap. Tested units exhibited an average …

Golden Age Or Gilded Cage? The Rise And Dissolution Of The Olympic Art Competitions, 1912–1948, Stella E. Gatziolis

Young Historians Conference

In 1912, Baron Pierre de Coubertin’s modern day Olympics celebrated not only its five year anniversary, but the first inclusion of the Olympic Art Competitions. Resembling a neo-Renaissance, Coubertin envisioned a “balance of the muscle and the mind” through the unity of the physical and intellectual. But by 1948, the art competitions had collapsed, leaving the social experiment to be forgotten by future generations. Drawing upon personal testimony from Coubertin and his loyal successors, and records from the International Olympic Committee, this paper explores how Coubertin’s extreme dedication to a pure and sanctified Neoclassical ideal led to the art competition’s …

Little Africa In Global China: Transnational Nigerians In Guangzhou And The Making Of Xiaobei, Tess L. Nestel

Young Historians Conference

This paper will examine the history and development of transnationalism fostered by Nigerians in Guangzhou, China, after the late 1990s. Spurred in part by the Asian Financial Crisis, Nigerian men flocked to Guangzhou’s thriving import-export economy. They established the ethnic enclave of Xiaobei, where many lived and engaged in the informal wholesale economy. Nigerians existed between the cultural boundaries of Xiaobei and Lagos, where they constantly returned. Both the export economy in Guangzhou and the resale economy in Lagos’ street markets were deeply influenced by one another through entrepreneurial migrants. This paper will provide a general overview of the many …

From Mogadishu To Minneapolis: Transnational Political And Social Ties In The Somali Diaspora, Kate E. Mcfarland

Young Historians Conference

Beginning in the 1980s, Somalis have fled Somalia in order to escape persecution and political violence, find new economic opportunities, and achieve a better life. One major destination of these migrants is Minneapolis, Minnesota, which is now home to over 80,000 Somalis, making up 18% of Minneapolis’ population. Due to this sizable Somali enclave, Minneapolis and Somalia have created and maintained a transnational relationship. This paper examines that relationship, focusing on the causes of the Somali diaspora, evidence of transnational connections (such as remittances, cultural exchange, and political effects), and the challenges that threaten this tie. Understanding this relationship is …

The Great Plague Of Marseille, Lucy Herzig

Young Historians Conference

This paper examines the causes and consequences of the Great Plague of Marseille (1720-1722), which was one of Western Europe's last major outbreaks of the bubonic plague. Although European port cities had developed quarantine systems to prevent epidemics, Marseille’s outbreak revealed how these protections failed in practice. This paper argues that the plague became so devastating not because of a lack of institutional systems, but due to fragmented local authority, delayed government intervention, and the prioritization of economic interests over public health. Focusing on the arrival of the merchant ship Grand-Saint-Antoine, this paper analyzes how merchant elites influenced quarantine decisions, …

A Battle Of Will And Wisdom: Polar Opposites In The Polar Extremes Of The Viking World, Lily C. Manne

Young Historians Conference

This paper explores the connection between the polar climate of Viking-age Scandinavia and the success of the Vikings through examining the dual nature of their culture brought about by their environment. The Scandinavian peninsula is known for its harsh, variable climate full of cold winters and unpredictable harvests that turned into long summers and melting fjords. Outside of shaping survival strategies and material culture, this polar environment seeped into the fundamental cultural values the Vikings exhibited, creating the foundation for a society that understood the value of destruction and violence as well as creation and craftsmanship. Using Norse mythology as …

The Kraken Wakes: Myth, Science, And The Rise Of A Maritime Sensation, From 1750-1900, Leif G. Crockett

Young Historians Conference

Since the 1800s, the legend of the Kraken has pervaded literature, but this creature is much older, figuring in Norwegian myths as early as the 13th century. The modern understanding of the Kraken can be traced back to the 1750s writing of Bishop Erik Pontoppidan, who described the monster with fantastical and analytical detail. An interrogation of Pontoppidan’s text, as well as novels, poetry, and other media sources from the 19th century—many of which reference the Bishop by name—uncovers Pontoppidan’s influence on later stories of the Kraken. Coupled with an analysis of secondary scholarship on the changing dynamics of science …

Demonizing Sexuality: Dangerous Women In Folklore, Lily E. Nelson

Young Historians Conference

Cross-culturally, women in folklore have been portrayed as dangerous due to their sexuality and influence over men. Clear patterns throughout history emerge through analysis of the following occurrences, which show a link between how sexualized a female figure is and the threat she is considered to pose. The she-demon Lilith in Jewish and Mesopotamian mythology as well as folklore relating to the Scriptures, mermaids in Europe, and fox spirits in East Asia all demonstrate this phenomenon, since they are all overly sexualized and represent broader social norms towards women. These beings all exhibit similarities in being able to exert control …

Key Issues For Speed Safety Cameras: Results From A Semi-Structured Interview Of Agencies In The United States, Sophia Semensky, Miguel Figliozzi

Civil and Environmental Engineering Faculty Publications and Presentations

Speed safety cameras (SSCs) are a recognized countermeasure for targeting speeding-related crashes, injuries, and fatalities. SSCs have been introduced in various cities and are steadily expanding in use both in the U.S. and internationally. The extensive literature review of domestic and international documents and research papers reveals that the U.S. has been comparatively slow to adopt SSCs, with some other countries implementing these systems more extensively and earlier. Many local agencies are eager to learn SSC best practices and implementation lessons within the U.S. context. In this research, key issues related to SSC implementation are explored through semi-structured interviews with …

Artificial Intelligence In Dental And Orthopedic Skeletal Imaging: A Scoping Review Of Methodological Convergence And Translational Gaps, Man Hung, Isabella Strickler, Annabella Jensen, Bayler Gunnell, Alicia Parry, Samuel Dyal, Martin S. Lipsky

Institute on Aging Publications

This scoping review aimed to answer the question: to what extent do artificial intelligence applications in dental and orthopedic skeletal imaging demonstrate true cross-disciplinary methodological convergence versus parallel development with shared translational barriers? This scoping review synthesizes AI applications across both fields to characterize methodological overlap, developmental asymmetries, and translational gaps, rather than assuming convergence. Following the PRISMA-ScR reporting standards, we searched PubMed, Scopus, Web of Science, IEEE Xplore, and EMBASE for peer-reviewed, English-language human studies published between January 2015 and May 2025. Eligible studies applied AI, machine learning, or deep learning to diagnostic, segmentation, or preoperative planning tasks in …

Vacuum Modification Of The Surface Properties Of T15k6 Hard Alloy By Plasma–Chemical Synthesis Of Tin-Cu Coatings, Aleksandr Semenov, Dmitriy Tsyrenov, Nikolay Ulakhanov, Irina Semenova, Undrakh Mishigdorzhiyn, Wen Ma, Simon C. Tung, George E. Totten

Mechanical and Materials Engineering Faculty Publications and Presentations

The design and main parameters of a plasma–chemical reactor containing two compartments are presented. One compartment houses a vacuum-arc evaporator, while the other houses a planar magnetron. The compartments are separated by a diaphragm with a dosing slot for injecting copper vapor into the TiN synthesis compartment. The conditions for the synthesis of superhard TiN-Cu composite coatings are experimentally determined. Based on established process parameters for TiN synthesis in a nitrogen-containing plasma by Ti evaporation using a vacuum-arc discharge, it is proposed to apply TiN-Cu coatings by injecting Cu vapor into the TiN synthesis area and sputtering Cu using a …

Psychometric Analysis Of The German Version Of The Barriers To Healthcare Checklist-Short Form, Judith Peth, Nicole David, Sophia Duckert, Petia Gewohn, Daniel Schottle, Pascal Rahlff, Alexander Konnopka, Hannah Konig, Kai Vogeley, Christina Nicolaidis, Dora M. Raymaker, Holger Schulz

School of Social Work Faculty Publications and Presentations

Background: Autistic people face multiple barriers to health care. To recognize specific barriers in a standardized way, autistic people, health care providers, and researchers need a suitable measure. The Academic Autistic Spectrum Partnership in Research and Education successfully developed the Barriers to Healthcare Checklist— Short Form (BHC-SF). It remains unclear whether (1) a German version of the BHC-SF performs well in terms of psychometric properties and (2) the BHC-SF consists of multiple constructs (i.e., assessing structural validity). Methods: We created a translated and culturally adapted version of the 17-item BHC-SF and used it with 345 autistic people in Germany. Psychometric …
