Structure–Optical Property Relationships In Amm′Q3 Chalcogenides, Ayat Tassanov, Huiju Lee, Daniel W. Spainhour, Yi Xia, James M. Hodges

Mechanical and Materials Engineering Faculty Publications and Presentations

Ten ACuHfQ₃ (A = Na, K, Rb, Cs; Q = S, Se, Te) chalcogenides were prepared via high-temperature solid-state methods and structurally characterized using single-crystal X-ray diffraction. The type-I AMM′Q₃ structures are defined by the arrangement of HfQ₆ octahedra (O) and CuQ₄ tetrahedra (T) in their layers, which adopt either OTOT (Cmcm, Pnma) or OOTT (Pnma, P2₁/m) connectivity. UV–vis absorption and photoluminescence spectra indicate optical band gaps ranging from 1.2 to 1.7 eV and reveal that OTOT and OOTT variants have direct and indirect band gaps, …

Low Cost Lightning Localization At Microwave Frequencies, Bradley Glaubitz

Dissertations and Theses

High precision lightning localization is essential for atmospheric research and public safety, yet the high cost of traditional VLF/LF systems restricts high resolution detection primarily to well funded agencies. Furthermore, conventional low frequency receivers often overlook microwave frequency emissions associated with lightning leader development. This thesis proposes a compact, low cost microwave frequency localization system operating in the 1.42 GHz band to provide an accessible alternative for high resolution mapping. The methodology utilizes an ARM Cortex M0+ microcontroller and a triggered 64 MHz 32 bit counter synchronized to a GPS Pulse Per Second (PPS) signal, achieving a temporal resolution of …

Flexible Load Communication Protocol Mapping Guide: Ieee 2030.5 To Ansi/Cta-2045, Joseph D'Ambrosia

Dissertations and Theses

As more variable renewable energy resources are connected to the grid, new challenges emerge for grid operators. Demand response programs can provide an additional degree of freedom to grid operators, by modulating the patterns of electricity consumption of residential, customer-owned, flexible loads. The success of demand response programs requires robust and reliable systems of communication between grid operators and flexible loads.

The ANSI/CTA-2045 communication protocol enables customer-owned devices to act as flexible loads. The SEP 2.0/IEEE 2030.5 communication protocol is used to manage distributed energy resources, including flexible loads. Interoperability can be realized by mapping ANSI/CTA-2045 and SEP 2.0/IEEE 2030.5 …

The Kashmir Conflict After The Abrogation Of Articles 370 And 35a Of The Indian Constitution: Geopolitical Dynamics And Human Security Implications, Rizwan Ali

Dissertations and Theses

The abrogation of Article 370 of the Indian Constitution on August 5, 2019, revoked the special autonomous status of Jammu and Kashmir (J&K) under the Indian administration. It further bifurcated it into two Union Territories under central Indian control. The move came amid a severe security lockdown and communication blackout that lasted for months. It was followed by instrumental legal, social, and economic developments that directly affected the area’s disputed status and the human rights of its residents. This research examines the geopolitical and human security implications of the abrogation and subsequent developments through a qualitative, analytical design, integrating Edward …

The Experiences Of College Students Facing Housing And Financial Insecurity, Nora Shaheen

University Honors Theses

Housing and financial insecurity among college students continues to be a growing crisis, yet their lived experiences are often overlooked. This thesis utilizes qualitative research to investigate the emotional, social, and academic experiences of students navigating housing and financial instability. The data was collected through semi-structured interviews with six current/former college students who have experience with housing and financial insecurities. During the analysis, recurring patterns were grouped into themes, including the triggers of instability (familial abandonment, rent increases, relationship dissolution, etc), social stigma and internalized shame, emotional and mental health costs, social isolation, survival strategies, food insecurity, work-school balance, disrupted …

(Re)Claiming Homeplace: Dance As Embodied Resistance & Healing For Health & Spatial Justice, Preeya G. Kannan

University Honors Theses

This thesis argues that dance functions as both an upstream public health intervention and a form of radical spatial resistance; creating healing, agency, and belonging among historically marginalized communities. Drawing on bell hooks' concept of homeplace, Jasbir Puar's assemblage theory, Nancy Krieger's eco-social theory, and Katherine McKittrick's Black geographies, I position the body as both an ecological and political landscape shaped by histories of colonialism, racial capitalism, displacement, and resilience.

Through this community-based participatory research study, Homeplace, I explore dance as a form of social prescription that centers liberation rather than pathology. Movement is often reduced in public health discourse …

So You Didn't Write The Next Great Novel (And How To Move Forward Knowing You Probably Won't), Adriana Stanzione

University Honors Theses

This thesis discusses the relationship between creative ambition and the paralyzing effects of perfectionism within the writing process. By analyzing this relationship via a lens on philosophy, psychoanalytic theory, and personal experience, it argues that the obligation and pressure to produce "good" work can often prevent sincerity and creative momentum. Divided into several sections, it also delves into ideas like inspiration and the revision process, tying in my own experiences with drafting my first manuscript, which resulted in years of writer's block and cynicism. The thesis also considers how cultural conditions contribute to creative stagnation, and deconstructs the concept of …

Assessing Spatial Distribution Of Plausible Earthquake-Triggered Landslides Relative To Ca. 1000 Ybp Earthquake On The Gales Creek Fault, Jacqueline Rheingans

University Honors Theses

Modern coseismic landslides cluster near the surface trace of the fault that ruptured, suggesting that clustering of paleolandslides may record information about paleoearthquakes. This study documents the pattern of prehistoric landslides near the Gales Creek Fault (GCF), northwest Oregon, to assess whether it reflects an independently known paleoearthquake. The GCF is located northwest of Portland through the Cascadia fore-arc basin where landslides are often triggered by intense rainfall during the wet season or potentially by seismic shaking on the megathrust or on crustal faults. In order to understand how a seismic event on the GCF will impact landslide distribution I …

Skeletons Vs. Mummies: Osteological Trauma On Bog Bodies As A Measure For Cultural Change In Ancient Europe, Miranda Hoodenpyl

University Honors Theses

Bog bodies are some of the most well known archaeological finds in the world, and are preserved human remains found in wetlands. Researchers use the information stored in the bones of bog skeletons and mummies to learn about cultural lifestyles, travels, diet, and diseases throughout time in Northern Europe and the British Isles. Through multiple cultural changes and migration, the "bog body phenomenon" has remained an unusual treatment displayed throughout time. This literature review looked at skeletal trauma on bog remains to identify cultural change over time in Northern Europe and the British Isles, spanning the Neolithic, Bronze, Iron, and …

Strategic Anti-Transgender Policy Diffusion: Interest Groups, Courts, And The Two-Track Politics Of Gender Regulation, Henry Danford

University Honors Theses

This thesis analyzes the strategic diffusion of anti-transgender policy in the United States following the passage of Idaho House Bills 500 and 509 in 2020. It argues that conservative lawmakers and advocacy organizations employed a coordinated "two-track" policy strategy in which transgender sports bans served as highly visible and politically popular mode legislation while identity-document restrictions advanced more quietly through courts and administrative policy. Drawing on policy diffusion theory, the Advocacy Coalition framework, and minority stress theory, the study combines qualitative policy analysis with quantitative analysis of Household Pulse Survey mental health data and Media Cloud new coverage data from …

Custom Sbc Gps Tracking And Geocaching Carputer Software Development And Implementation, Joshua A. Davis

University Honors Theses

This thesis argues that hardware-integrated capstone projects develop software engineering skills that traditional coursework cannot replicate. A team of eight developers built a GPS tracking system on a Raspberry Pi 4 over two academic terms, integrating real-time position streaming, the APRS amateur radio protocol for network-independent location sharing, and PostGIS spatial queries for "new road" detection. The system implements SmartBeaconing for adaptive GPS data reduction, achieving approximately 80% storage savings while preserving route fidelity. The project exposed challenges absent from classroom assignments: hardware debugging without stack traces, cross-layer integration failures, and coordination overhead when deploying to unfamiliar architecture; demonstrating that …

Brutalism, Bad Manners, And Tech Baddies: Strengthening Women's Sense Of Belonging In Undergraduate Computer Science Spaces, Mckenzie Starr West

University Honors Theses

Through a literature review supported by reflexive vignettes, this thesis explores women's experiences in undergraduate CS programs and how physical and discursive spaces may affect their sense of belonging and shape whether they enter, remain in, or leave CS programs. I provide historical and cultural context for undergraduate CS, including the history of women in education and the continued underrepresentation of women in CS compared to many other STEM fields. Using physical and discursive spaces as a lens, I examine how classrooms, study spaces, department communications, online forums, and other CS-related environments may signal who belongs, who is valued, and …

You Burn With Us: How Fire Functions In Suzanne Collins' The Hunger Games Trilogy, Lucy Evans

University Honors Theses

This paper examines Suzanne Collins' The Hunger Games trilogy and how fire behaves as a multifaceted element that constructs, exposes and transforms power. Through tracing the development of the protagonist, Katniss Everdeen, this research explores how fire evolves from a weapon into a symbol for revolution. This analysis uses the framework of other dystopian novels, and previous character analysis of The Hunger Games, to understand Katniss's role in the revolution of Panem. It does so through three main behaviors: the construction of Katniss's "girl on fire" persona that commodifies her for the capitol's gain; the exposure of the state's …

Transforming Equity: A Systemic Analysis Of The Equity Model Of Social Justice Education Through The Lens Of Conflict Transformation Theory, Precious J. Golden

University Honors Theses

Current pedagogical theory and practices grounded in social justice aim to rectify systemic barriers to equity, yet despite decades of teaching through a social justice lens, social inequality and cultural division are on the rise.  "Justice," as a noun, has several meanings (Cambridge Dictionary). It can mean "judge", "law," or "fairness," and justice, no matter its meaning or its need, is achieved through methods of conflict resolution and conflict transformation. This inquiry seeks to present conflict transformation as a radical means of achieving transformative social justice, bringing voice to the voiceless and oppressed, and rectifying the contradictions in the current …

"But Oh, What Harm Those Basics Would Cause": How Journalists Can Better Interview Vulnerable Sources Utilizing An Ethic Of Care, Noah Carandanis

University Honors Theses

Traditional journalistic ethics have emphasized detachment from sources and objectivity guiding journalists' practices. In this thesis, I explore the contribution of care ethics to the field of journalistic ethics, emphasizing care in relation to interviewing vulnerable sources. I claim that the traditional objective, detached ethical status quo in journalism is insufficient in the context of reporting on mass shootings. This thesis argues that caring journalistic practices should be utilized when interviewing traumatized, vulnerable sources. In the first part, I present the issue of traditional journalistic practices through my personal experiences. I also discuss the philosophical underpinnings to journalist's objectivity criterion. …

Irish Identity: Symbols Of Nationalism In W.B. Yeats's Cathleen Plays, Emma Mady

University Honors Theses

William Butler Yeats was one of the leading figures of the Irish Literary Renaissance. Two of his plays, The Countess Kathleen (1892) and Cathleen ni Houlihan (1902) portrayed themes of nationalism and revivalism in strikingly different ways. Each play uses figures from folklore and mythology to establish a sense of national identity: the tale of "The Countess Kathleen O'Shea" inspired The Countess Kathleen, and the Irish Sovereignty goddess inspired the figure of legendary Cathleen ni Houlihan. The Countess Kathleen was met with harsh criticism and accusations of blasphemy, while Cathleen ni Houlihan is still widely regarded as Yeats's …

Jalzap: An Agile Hybrid For Ai-Accelerated Software Development, Pouya Nouri

University Honors Theses

The rapid adoption of generative AI tools allows software teams to quickly code applications, but it comes at a cost: high scope volatility, technical debt, and unrealistic expectations, which break traditional Agile frameworks. This thesis introduces JALZAP, a lightweight, hybrid Agile framework designed to serve small, high-agility teams facing compressed timelines and unpredictable schedules. This framework was evaluated over 16 weeks through a Portland State University Capstone project working for a pre-seed startup sponsor, where a six-person team built Flowmind: an AI-powered iOS task management app meant to serve users with neurodevelopmental disorders like ADD/ADHD. JALZAP implements structural boundaries, including …

Effects Of Fine Sediment On The Productivity Of Stream Ecosystems In The Pacific Northwest, Veena I. Davis

University Honors Theses

Salmon are important to the culture, ecosystem and economy of the Pacific Northwest. However, populations have declined significantly since European colonization. Salmon require specific conditions for each life stage and are highly sensitive to environmental stressors. Excess fine sediment is a leading form of pollution as it degrades salmon spawning habitat and the benthos upon which their main food source, stream insects, live. To evaluate the effect of sediment pollution on food availability for salmon smolt, we conducted an experiment  estimating the amount of stream insect biomass and calories lost due to sediment pollution. We counted insects on substrate samples …

Aid As Leverage: How Humanitarian Assistance Shapes The Health Power Dynamics In Eastern Democratic Republic Of Congo, Emmanuella K. Mbuyu

University Honors Theses

This paper examines humanitarian aid in the Eastern Democratic Republic of Congo, where it serves as both relief and a force reshaping local power dynamics within ongoing conflict. Humanitarian organizations provide essential services in contexts of state collapse, but aid delivery is deeply embedded in systems of coercion, negotiation, and external influence. Drawing on critical humanitarianism and the aid economy, this study analyzes how humanitarian access is negotiated, how donor priorities shape definitions of need, and how temporary interventions create dependency and instability. The paper explores how humanitarian action can reinforce alternative structures of authority, particularly in weak or absent …

Staging Reception / Perception: Transhistorical Bi-Directional Dialogues Between Etruscan Visual Cultural Objects And Giuseppe Penone's Contemporary Sculptures, Shelby Morgan

University Honors Theses

I use the occasion of the March 2024 exhibit,"Vulci. Goods for Mankind. Goods for Gods." at Milan's Luigi Rovati Foundation to consider how the museum's staging of Etruscan visual material cultural objects and contemporary sculptures by Italian artist Giuseppe Penone prompts viewers to perceive transhistorical bi-directional dialogues between the viewer and material culture as well as between the ancient and contemporary objects themselves.

Via a close reading of the exhibition while leveraging the three frameworks of aura, imprint and classical reception I analyze how the staging of the hypogeum creates a place of atmosphere. I argue this is done through …

More Than "Programs For Women": Centering Incarcerated Women's Voices In The Evaluation Of Prison Programming, Winter Ohara-Frantz

University Honors Theses

This thesis examines whether correctional programming in women's prisons reflects the self-identified goals and aspirations of incarcerated women. Existing research demonstrates that prison programming can provide meaningful benefits, including skill development, emotional growth, and preparation for reentry. However, much of this scholarship evaluates women based on institutional outcomes rather than asking whether available programs align with women's own educational, vocational, and personal goals. Drawing on survey responses from 23 formerly incarcerated women across the United States, this mixed-methods study explores participants' experiences with vocational, post-secondary, parenting, and other correctional programs. Quantitative findings indicate that while most respondents viewed programming as …

Testing Potential Correlations Between Childhood Lead Exposure And Authoritarianism In Adulthood, Kragen Anderson

University Honors Theses

A significant body of research links lead exposure during childhood to negative effects ranging from increased impulsivity to societal level effects such as an increased likelihood of committing violent crime in adulthood. Due to exposure vectors such as lead water pipes, lead solder, lead based paints, and leaded gasoline there was significant lead exposure during childhood for large portions of the American population. This paper tested and found a statistically significant association between average population level lead exposure in childhood and likelihood of voting for candidate Trump later in life.

Healthcare Access Challenges Among Asian Americans, Phyo Theingi

University Honors Theses

Asian Americans are the fastest growing racial ethnic group in the U.S. According to the 2023 U.S. Census Bureau population estimate, Asian Americans account for 25.2 million (or 7.4%) of the nation's population. Asian Americans are not a monolith and represent a diversity of rich histories, cultures, languages and ethnicities. According to research conducted by the Pew Research Center, most Asian Americans face discrimination of some kind, including being treated as a foreigner in the U.S and being stereotyped as a model minority. They also experience health care access barriers. Research found that Asian Americans face barriers related to language …

Singing As Liberation: Spiritual Imagination And An Embodied Practice Of Hope Through Spirituals And Songs Of The Uhadi, Matisse Geselle

University Honors Theses

An exploration of the spirituality and the sacredness of music—and especially singing—through recording my own interpretations of spirituals and songs of the uHadi. It is also a poetic inquiry into how imagery of the river is used in spirituals as a pathway to freedom and liberation, and how the singing of spirituals is hope embodied. And it is a reflection of how my experience of the uHadi and my friends of the Ibuyambo ensemble changed me. The process of working on this project also feels like I am connecting to myself—and others—more deeply through singing. And ultimately, I hope for …

Characteristics Of Social Capital In Informal Housing Settlements, Lena Parsons

University Honors Theses

Many cities see growth of informal housing settlements as urban populations rise across the globe. Residents of informal settlements are observed to use robust networks of social capital to support themselves in an environment of resource scarcity and marginalization. This review synthesizes research examining characteristics of social capital in informal housing settlements, finding that (1) social capital influences residents' acquisition of basic needs, (2) the structure of social capital networks depend on the context of the settlement, and (3) the built environment of informal settlements has a cyclical relationship to their social capital networks. This synthesis concludes that formal solutions …

"What About Me?": Explaining Voting Patterns Among Young Men In The 2024 Election, Camille Moore

University Honors Theses

This study analyzes the recent rightward shift in voting patterns among Gen Z men in the 2024 election cycle and beyond. Drawing on procedural justice theory, it argues that deterrence from the Democratic party, rather than appeals from the opposition, was the primary driver of the shift, and that this deterrence reflects perceptions of procedural unfairness and exclusion from Democratic party agendas and policymaking platforms. A qualitative empirical analysis, including interviews with a politically and demographically diverse sample of men aged 21-26 in Oregon, supports this argument. Participants felt unjustly excluded from the left based largely on identity-related concerns and …

Seeing A Future Where I Exist As Myself: An Exploration Of Suicidality As A Response To Sociopolitical Oppression In Transgender And Gender Expansive Populations, Alexander Ray Sequoia

University Honors Theses

Suicide is often considered a mental health issue alone. For Transgender and gender non-conforming (TGNC) people, suicide can be a response to erasure of self and living under oppression conditions. The sociopolitical climate in the United States (U.S.), has become more hostile for TGNC people, along with legislative action that criminalizes their existence. This project explores the intersections of identity and nuances of suicide and death. The present study consists of 14 semi-structured interviews. This study examined the intersections of gender and culture on suicide responses, highlighting the importance of culturally relevant and community-led support for Transgender and gender expansive …

Understanding Moral Injury In Emergency Department Clinicians: Predictors, Outcomes, And Evidence Gaps, Rose Doering Lightspeed

University Honors Theses

Moral injury (MI) is an emerging construct for understanding clinician distress in high-acuity healthcare settings, yet its application to Emergency Department (ED) clinicians remains limited. MI refers to psychological distress resulting from exposure to, or participation in, situations that conflict with deeply held moral or ethical standards, often due to systemic or organizational constraints. Although prior research has examined MI in heterogeneous healthcare samples, the ED remains underexamined despite its unique combination of high patient acuity, throughput pressure, and resource limitations.

This review synthesizes literature on MI among healthcare workers with a focus on ED clinicians, drawing on Industrial-Organizational psychology …
