This study examines differences in patient demographics, hospital characteristics, and outcomes among GBS admissions to rural versus urban hospitals in the United States.

Methods: Using the 2021 National Inpatient Sample, we conducted a retrospective cohort study of adult hospitalizations with a principal diagnosis of GBS. Hospitals were classified as rural or urban based on U.S. census designations. Multivariate logistic and linear regression models were used to assess associations between hospital location and outcomes, adjusting for demographic, clinical, and hospital-level factors. …

Ultra Fast Calorimeter Simulation With Generative Machine Learning On Fpgas, P. Alex May, Qibin Liu, Julia Gonski, Benjamin Nachman

Faculty Research, Scholarly, and Creative Activity

Computationally expensive, high-accuracy detector simulations are a major bottleneck for many particle physics experiments such as those at the Large Hadron Collider (LHC) as well as those planned for future colliders. This challenge has motivated the development of fast generative machine learning based surrogates. We present a hardware-aware variational autoencoder model for fast calorimeter simulation that is designed specifically for field programmable gate array (FPGA) deployment, offering faster and lower power inference capability. Quantization aware training and other compression techniques are applied to respect the resource constraints of a single FPGA. The synthesized implementation of the VAE decoder achieves sub-millisecond …

Faculty, Staff and Students Publications

Corneal innervation research has faced long-standing clinical challenges that only recent technological breakthroughs now make tractable. Advances in single-cell analysis, viral vectors, clinical imaging, and artificial intelligence provide integrated approaches for uncovering molecular mechanisms underlying functional outcomes and facilitating clinical applications. The National Eye Institute's U01-funded consortium on ocular surface innervation addresses major knowledge gaps in characterizing corneal-projecting neurons, understanding neuroimmune and epithelial interactions in the cornea, and translating animal model findings to human pathology. The unique properties of the cornea (transparent, avascular, and densely innervated) make it ideal for neurobiology research on peripheral and central sensory processing. Through a …

Why Choose Green Burial: Raising Awareness About An Under-Utilized Method Of Body Disposition, Gretchen Mahlberg

University Honors Theses

Green burial, the process of human burial in a biodegradable vessel without embalming, is a simple method for disposal of remains that has been used around the world for centuries, yet it is chosen less than 5% of the time in the US today. The stigma about discussing death has led to a lack of awareness about options and created an environment where morticians, as the sole sources of information, direct the bereaved towards the options most beneficial to themselves. Previous methods to raise awareness about green burial have had limited reach, being focused on people who are already researching …

Familial Roles In Grief With A Focus On Eldest Daughters In Latinx Communities, Julianna Falcon

However how grief impacts eldest daughters within the Latinx community and their familial roles is a subject that has had little to no research done thus far. The four participants in this exploratory study describe their own experiences with the shift in familial roles and their experience navigating grief. They all shared their experiences through semi-structured interviews. Where the findings displayed key themes surrounding expectations, support, proximity, and academic impacts within each of the interviews. More detail is provided within this study on how …

Systematic Identification Of Cell-Cell Interactions Associated With The Severity Of Patients With Alzheimer’S Disease, Zijian Zhang, Naail Chowdhury, Jing Dong, Lang Wu, Chao Cheng

Faculty, Staff and Students Publications

Background

Alzheimer's disease (AD) is a complex, multifactorial neurodegenerative disorder involving dysfunction across multiple brain regions. While accumulating evidence has implicated the roles of diverse cell types, including neurons, glia, and vascular cells in AD pathogenesis, it is still poorly understood how cell type interactions drive or respond to the disease progression and severity.

Objective

This study aimed to systematically characterize cell-type–specific alterations and intercellular communication changes associated with AD progression.

Methods

We leveraged the transcriptome profiling and a previously established statistical framework to present a comprehensive mapping of the cellular interaction landscape in the human brain of AD.

Interrupted By Design: The Impact Of Push Notifications On Stress And Task Performance, Mia Hohmann

University Honors Theses

As digital communication becomes unavoidable at work, notifications have become one of the most common and overlooked sources of interruption. Drawing from current technostress literature, this study investigates how notifications impact acute and perceived stress as well as task speed and accuracy. In an experimental setting, employed university students (N = 35) completed a data-entry task while receiving either no notifications, task-relevant notifications or task-irrelevant notifications to examine how different types of digital interruptions influenced stress and performance. Stress was measured through a pre- and post-task survey and performance was assessed through both speed and accuracy. Although results showed significant …

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 …

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, …

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 …

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 …

"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 …

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 …

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 …

Bringing The Focus Of Curriculum Back To The Students And What Does This Look Like For Teachers, Gabriella Anaya

University Honors Theses

As a future ELA teacher, I was curious about how the books students read influence their learning. Specifically, I wondered: How does letting students choose their own books impact reading comprehension outcomes? Studies suggest that the reading materials were not necessarily what we should be focusing on, rather the teaching methodology and how it implements reading materials. The key methodology that contributed to reading comprehension improvement was instilling motivation in students by fostering student autonomy over their own learning in the classroom. This is the main idea in which my research concentrates on connecting research on reading comprehension with practical …

Educational Leadership Styles And School Outcomes: Correlational Evidence From Texas, Djenane Bolton

Electronic Theses and Dissertations

This quantitative study examined the relationships between principal leadership styles and educational outcomes within Texas’s high-stakes accountability system. Federal reforms such as the No Child Left Behind Act and the Every Student Succeeds Act increased accountability and pressure on public schools, making principals the primary agents of student performance and school effectiveness. In Texas, these ideals were reinforced by standardized assessments, accountability ratings, and teacher and leader evaluation systems, underscoring the need to understand how leadership styles affected this environment. The purpose of this study was to investigate the relationships between instructional, directive, and participative leadership styles and the factors …

Expanding The Omop Common Data Model To Support Extracorporeal Life Support Research, Clemens Rieder, Ahmed Said, Et Al.

2020-Current year OA Pubs

OBJECTIVE: Despite the increased availability of electronic health records, open-source standardized data collection to facilitate high-resolution data during extracorporeal life support (ECLS) is lacking. This project aimed to assess the Observational Medical Outcomes Partnership Common Data Model (OMOP CDM) for interoperability to store data sufficiently generated in the context of ECLS and to develop a custom data model expansion in case the OMOP CDM proved insufficient.

DESIGN AND SETTING: The OMOP CDM was analyzed qualitatively by expert consensus for its capability to capture data relative to ECLS as well as the presence of fitting ECLS-related concepts. Database entries necessary to …

Golden Hour Open Conceptual Architecture For Citizen-Initiated Structured Urgency Signaling, Jaime Gerardo Figoni Him

Defensive Publications Series

Abstract Golden Hour proposes a minimalist, open, and low-bandwidth emergency signaling architecture that enables any citizen to transmit structured urgency information during the critical first hour (“Golden Hour”) of a disaster. The system combines a single-tap severity code (Red / Yellow / Green), a brief guided question sequence, and resilient transmission paths (including SMS/USSD fallback) to generate a live, color-coded situational heat map for emergency responders.

By treating emergency response as a problem of controlling informational entropy, Golden Hour enables a near-instantaneous reduction in chaos while fostering voluntary human solidarity. It is designed as a supplement to — not a …

Dissertatin' While Black, T. Gertrude Jenkins

Black Educology Mixtape "Journal"

Dissertatin’ While Black (DWB) is a racial affinity space that employs a community-engaged approach to completing dissertation elements. More than a writing retreat, DWB centers holistic care, creating a site for mentorship, celebration, and the exchange of ideas. Rooted in BlackCrit (Dumas & ross, 2016) and Black Liberatory Educational Subversion (Jenkins, 2024), DWB emphasizes that participation in Black institutional third spaces can counter the isolation often experienced by Black doctoral students, especially at predominantly white institutions. Ultimately, DWB operates as a “homeplace” where Black doctoral students can feel seen, valued, and supported in their research (hooks, 1994). We believe that …

“Hip-Hop Permeates Everything I Do:” The Intersections Of Global Politics, Hip-Hop, And Education, Mecedes Lindsay

Black Educology Mixtape "Journal"

This qualitative study examines how the absence of Critical Hip-Hop Pedagogy (CHHP) within academic institutions shapes students’ sense of belonging, motivation, and engagement by regulating which forms of cultural capital are deemed legitimate. Drawing on semi-structured interviews and focus groups with students, educators, scholars, and members of the hip-hop generation, this research adopts an interpretivist framework to center participants’ lived experiences within educational spaces. Informed by Freirean critical pedagogy and Yosso’s theory of community cultural wealth, the study situates schooling as a site where America’s soft power operates through curriculum design, disciplinary norms, and definitions of deviance. Findings reveal that …

Purposefully Black Interactional Systems: Disrupting Punitive School Discipline Models Through Banter, The Funk, And The Black Aesthetic, S. M. Wilson

Black Educology Mixtape "Journal"

This empirical study seeks to understand the narratives of four Black men teachers and two Black women teachers about how they implement school discipline and classroom management in their K–12 contexts. This track draws on interdisciplinary perspectives from education, linguistic anthropology, and African American studies to understand how banter and ritual insults function as alternatives to traditional discipline. Phenomenology and thematic analysis of six semistructured interviews demonstrated Black teachers’ beliefs that outdated and punitive orientations should be challenged. These teachers enacted discipline through talk—particularly banter, ritual insults, and what I call “purposefully Black interactional systems,” which embed discipline within them, …
