This Capstone Review Thesis discusses the current structure of the Computer Science Degree path and Computer Science Capstone at PSU. This thesis reviews the Conello Vendor Marketplace Capstone, a project designed to help address the issue of teambuilding in the workplace. It points out ways in which teamwork and organization is an underdeveloped skill in Computer Science. During the Capstone project, the project management method of Agile development was recommended and used. 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 …

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 …

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 …

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 …

Her work has been part of several solo and group exhibitions within museums and galleries across the country and she was awarded the Oregon Governor's Award for the Arts in 1989. She is best remembered for her unique still life paintings, frequently painted in egg tempera, which sold immensely well during her lifetime and after. Haley trained at the Yale School of Art in the late 1920s and early 30s, where she learned to paint …

Agile In The Age Of Ai: Considerations And Improvements For Streamlining Developer Workflows, Stephen Feng

University Honors Theses

This paper examines the integration of AI language models into Agile developer workflows during a six-month software development project. Using the development of SagacityWall, a mindfulness-based social media application built by a team of eight undergraduates, it identifies three key areas in Agile processes where AI provided meaningful leverage: translating business requirements into actionable developer work tickets, accelerating framework research and technology stack decisions, and reducing onboarding friction through AI-assisted code scaffolding and Behavior-Driven Development story formatting. The study finds that AI meaningfully boosted productivity across these stages – not by replacing developer judgment, but by reducing overhead at each …

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 …

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 …

Coupled Ferroelectricity And Phonon Chirality, Xiang-Bin Han, Cong Yang, Rui Sun, Xiaotong Zhang, Thuc Mai, Zhengze Xu, Aryan Jouneghaninaseri, Xiaoning Jiang, Rahul Rao, Yi Xia, Multople Additional Authors

Mechanical and Materials Engineering Faculty Publications and Presentations

Recognizing the coupling between ferroelectricity and chirality in optically active ferroelectrics opens a route for manipulating chirality via ferroelectricity under an external electric field, enabling control over chirality-dependent quantum states. Here, we report the experimental demonstration of the coupling between ferroelectricity and phonon chirality in the molecular ferroelectric triglycine sulfate. By electrically switching the crystal chirality, we achieve reversible and device-compatible control of phonon chirality, as revealed by in situ time-resolved magneto-optical Kerr effect measurements. The Kerr rotation reverses with electric-field switching, while phonon chirality vanishes in the paraelectric phase and is tunable in the racemic ferroelectric state. Furthermore, density …

The Effect Of Incidental Emotions On Self-Control: An Examination Using A Need-Based Choice Model, Shruti Koley

Business Faculty Publications and Presentations

Purpose – The purpose of this paper is to develop a framework that examines the effects of incidental emotions on choices in self-control dilemmas. The framework predicts that the effect of emotions depends on the hedonic and non-hedonic needs they activate and the extent to which emotional consumers expect the virtuous and gratifying options in the choice dilemma to facilitate these needs (i.e. their instrumentality toward the activated needs). The framework helps develop propositions for the self-control effects of six commonly experienced emotions: happiness, sadness, pride, guilt, anger and anxiety. Design/methodology/approach – The author uses a choice model to develop …

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 …

Isometric Force Characterization Of Braided Pneumatic Actuators, Ben Bolen, Mohammad Elzein, Lawrence Pang, Alexander Hunt

Mechanical and Materials Engineering Faculty Publications and Presentations

Artificial muscles such as braided pneumatic actuators (BPAs) offer many advantages for robotic systems, including high durability and strength-to-weight ratios. However, their use in robotic systems is still extremely limited, in part due to their poor force, length, and pressure characterization. In this work, a test setup is created to compare force produced by Festo fluidic BPAs with leading models. Our analysis of the data has resulted in (1) the development of new equations to calculate force as functions of pressure and contraction for Festo BPAs with uninflated diameters of 10 mm and 20 mm, and (2) a novel equation …

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 …

The Impact Of Mnar Attrition On Estimation Of Latent Growth Curve Models With Binary Observed Variables, Jason T. Newsom, Brian T. Keller, Mallory R. Kroeck, Nicholas A. Smith

Psychology Faculty Publications and Presentations

A Monte Carlo simulation was used to evaluate the performance of latent growth curve (LGC) modelswith binary observed variables when the attrition pattern was missing not at random (MNAR) for fivetime points. Parameter and standard error biases for three estimation methods were compared:weighted least squares with mean and variance adjustment (WLSMV), categorical robust marginal max-imum likelihood (categorical MLR), and Bayes. The results indicated that robust diagonal weightedleast squares paired with multiple imputation (MI) performed best when values were missing at ran-dom. When data were missing not at random, Bayesian estimates performed best.

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) …

¡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

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 …

An Integrated Framework For Memory-Centric Analysis: From Trace Collection To Co-Design, Dhruv Gajaria, Prajwal Challa, Yasodha Suriyakumar, Joseph Manzano, Nathan Tallent, Andrés Márquez

Computer Science Faculty Publications and Presentations

IntroductionThe memory wall phenomenon—where advances in processor performance significantly outpace those in memory subsystems-poses a fundamental challenge for contemporary computing systems. In memory-bound applications, memory subsystem behavior dominates performance, yet existing analysis approaches present significant limitations: detailed microarchitectural simulators require days to weeks to simulate modest workloads; hardware performance counters provide only aggregate statistics that obscure temporal and spatial access patterns; and scaled simulation approaches face challenges in capturing contention effects, bandwidth saturation, and interference patterns that emerge at larger scales. These limitations reflect a processor-centric design philosophy—in both performance analysis tools and system co-design methodologies—that is increasingly misaligned with …

An Open-Source Linear Actuated-Quartz Tube Furnace With Programmable Ceramic Heater Movement For Laboratory-Scale Studies Of Combustion And Emission, Casey Coffland, Ryan Bixler, Elliott T. Gall

Mechanical and Materials Engineering Faculty Publications and Presentations

The Linear Actuated Quartz Tube Furnace (LA-QTF) is an instrument engineered to heat and combust materials under controlled conditions, capable of achieving flaming and smoldering states. A ceramic ring furnace is linearly actuated parallel to the length of a quartz tube. The mode of combustion depends on temperature, fuel composition, and oxygen availability; the LA-QTF regulates combustion by controlling the temperature and position of the ring furnace, and airflow within the tube. The LA-QTF can maintain temperatures between 23 °C and 530 °C for extended time periods, with stable temperatures over long-duration (∼120 min) experiments. Flow rate is dependent on …

The Impact Of Optimization Approximation Algorithms On The Performance Of The Bht-Qaoa, Ali Al-Bayaty, Marek Perkowski

Electrical and Computer Engineering Faculty Publications and Presentations

This article investigates the performance impact of five classical optimization approximation algorithms on our previously introduced quantum search algorithm, termed the Boolean–Hamiltonians Transform for Quantum Approximate Optimization Algorithm (BHT-QAOA), to effectively search for all best-approximated solutions for Boolean-based problems. These optimization approximation algorithms are BFGS, L-BFGS-B, SLSQP, COBYLA, and COBYQA. Their performance impact is evaluated and compared using two proposed performance metrics—(i) the final number of function evaluations (the lower numbers denote the best optimization approximation algorithms) and (ii) the final quality of qubit measurements (the higher values indicate all best-approximated solutions were found for a problem). Arbitrary classical Boolean …
