"I'M Strictly T4t": Trans For Trans Connections In The Contemporary, Madi Lou Alexander

Dissertations and Theses

Trans for trans relationships, referred to as "t4t", are a relationship type specific to trans individuals. Linguistically originating from Craigslist personal ad spaces, t4t indicates a trans person seeking out and engaging with another trans person. The scope of relationships under the t4t label are often largely associated with sexuality and dating scenes due to their conception in online cruising spaces. Through qualitative analysis, I assess the range of what t4t relationships are through 30 in-depth interviews with participants identifying as trans. This work moves away from focusing on the deficits of holding a marginalized identity, instead aiming to center …

A House With No Walls Where Persimmons Grow In The Garden: Photography As A Collaborative Feminist Practice And Using Archives To Reframe The Present, Jada Wheeler

University Honors Theses

A House With No Walls is an investigation of the idea of chosen family, as it exists apart from the influence of any institution. It alludes to the home as a place that exists within space shared with the people we choose as family and within our own free bodies. This project investigates the collaborative potential of photography, and uses it as a tool in creating a feminist representation of family. All the photographs were made with close friends, in an unplanned and spontaneous manner, to document intimate moments of our everyday lives.

Spousal Bereavement Enhances Proinflammatory Cytokine Production To Acute, Psychological Stress., E Lydia Wu-Chung, Ryan L. Brown, Robert Suchting, Jensine Paoletti-Hatcher, Michelle A. Chen, Angie S. Leroy, Kyle W. Murdock, Cobi J. Heijnen, Christopher P. Fagundes

Psychology Faculty Publications and Presentations

Early widowhood is characterized by chronic stress and is associated with a higher risk of incident depression and cardiovascular-related morbidity and mortality. Peripheral inflammation is involved in the pathogenesis of major depressive disorder and atherothrombosis and may represent a common mechanism underlying widow(er)'s elevated risk for both health conditions. Chronic psychological stress sensitizes the release of proinflammatory cytokines during the peripheral stress response. The present study examined whether recent spousal bereavement enhances the inflammatory response to an acute, psychological stressor. Recently widowed older adults (n = 143) and non-widowed controls (n = 69) participated in a quasi-experimental study, during which …

Retention Intervention Program Success: An Inquiry Into Learning Organization Structural And Cultural Elements In California Community Colleges, Paul Vernon Wickline

Dissertations and Theses

Community colleges serve a diverse, underrepresented, and economically disadvantaged student population, yet most students fail to complete their academic goals, with students from marginalized groups facing even more significant disparities. Some colleges have implemented Early Alert and Intervention (EA&I) programs to improve retention and completion rates. However, colleges may face organizational challenges in implementing and sustaining these retention programs. This qualitative study examined structural and cultural elements in community colleges that have successfully implemented EA&I programs, focusing on student services and student affairs practices that support a learning-centered environment. Findings suggest that effective EA&I programs are grounded in inclusive, collaborative, …

The Role Of Cultural Mathematical Caring Relations In Supporting Two Latina Undergraduates’ Rate Of Change Development Within A Constructivist Teaching Experiment: An Anti-Deficit Investigation Bridging Sensemaking And Cultural Experiences, Christopher Orlando Roman

Dissertations and Theses

This study introduces cultural mathematical caring relations (CMCRs) as a framework that extends Hackenberg's mathematical caring relations by integrating two tenets of culturally relevant pedagogy: academic achievement and cultural competence. Framed within radical constructivism, CMCRs prioritize students' cognitive growth and development while affirming their cultural and experiential identities by embedding their funds of knowledge into the learning process. Through a constructivist teaching experiment with two Latina students, Yari and Jocelyn, this research investigates how working to establish and maintain CMCRs can influence Latin* students' rate of change development.

Findings illustrate that CMCRs supported the development of Yari and Jocelyn's rate …

Dissertations and Theses

This dissertation addresses the challenge of detecting frequency events in diverse power systems by enhancing existing frequency event detection methods through detection process modifications and developing unique tunable parameters. Since system characteristics differ across regions, frequency event detection algorithms must be customized by domain experts for each balancing area using tunable parameters. By optimizing these parameters for specific power system, the algorithms can accurately detect frequency events and can also be used for further analysis to determine trends in frequency events over time, ensuring system stability.

This dissertation focuses on the enhancement and optimization of frequency event detection algorithms. These …

The Effects Of Family Cohesion On The Relationship Between Trauma And State-Level Social Policy Provision In The United States, Brandon Kendall Ross Fielding

Dissertations and Theses

This dissertation examines how childhood trauma and family cohesion interact to shape state-level social policy generosity in the United States. The study begins with a multilevel quantitative analysis using data from the National Survey of Children’s Health and the State Safety-Net Generosity Index to assess how individual-level experiences of trauma and family support relate to state-level welfare generosity. Two trauma indices--one focused on adverse childhood experiences and bullying, and the other on food-related hardship--are used to explore how trauma influences attitudes toward public assistance, and whether family cohesion moderates this relationship. Results from marginal effects analyses indicate that family cohesion, …

An Exploration Of Holistic Admissions Protocol In Graduate School: Implications For Access And Equity, Kelly Doherty

Dissertations and Theses

Historically, graduate admissions policies at higher education institutions have heavily relied on standardized testing, which limits access to graduate and professional degrees for underrepresented demographic and gender groups. Recently, movements toward holistic graduate admissions processes and strengths-based evaluations of applicants have shown promise in equitably recruiting and admitting candidates. However, the field currently lacks common best practices and strategies for enhancing equity in the evaluation of applicant credentials. Furthermore, recent federal challenges to campus diversity and inclusion efforts have complicated these initiatives. To address these issues, this qualitative comparative case study examined five university graduate schools that are implementing holistic …

Enabling New Synthetic Platforms For Aryne Synthesis With Aryl Thianthrenium Reagents, Riley Augustus Roberts

Dissertations and Theses

The enormous importance of aromatic rings in organic molecules cannot be understated. Aromatic rings are present in the majority of pharmaceuticals, agrochemicals, and consumer products. The way in which these rings are arranged and substituted results in a molecule’s unique properties. Because of this, the current limitations of the chemical methods used to synthesize these molecules results in limited structural diversity and thus missed opportunities for the development of value-added products. To this end, this work demonstrates novel methods of aryne synthesis, aryl thianthrenium synthesis and a unique approach to structural scaffold hopping. The approaches presented herein allow for rapid …

Deep Learning Classification Of Drainage Crossings Based On High-Resolution Dem-Derived Geomorphological Information, Michael Edidem, Bill Xu, Ruopu Li, Di Wu, Banafsheh Rekabdar, Guangxing Wang

Computer Science Faculty Publications and Presentations

High-resolution digital elevation models (HRDEMs) from LiDAR and InSAR technologies have significantly improved the accuracies of mapping hydrographic features such as river boundaries, streamlines, and waterbodies over large areas. However, drainage crossings that facilitate the passage of drainage flows beneath roads are not often represented in HRDEMs, resulting in erratic or distorted hydrographic features. At present, drainage crossing datasets are largely missing or available with variable quality. While previous studies have investigated basic convolutional neural network (CNN) models for drainage crossing characterization, it remains unclear if advanced deep learning models will improve the accuracy of drainage crossing classification. Although HRDEM-derived …

Institutions, Indigenous Peoples, And The Structure Of Power In Columbia River Basin Salmon Governance, Christopher Michael Page

Dissertations and Theses

As broad patterns of behavior influenced by norms and rules, institutions structure many aspects of modern society through coordination and the distribution of power. Due to the importance of common-pool natural resources to many aspects of society, they usually involve competition and lie at the intersection of multiple institutions. This combination of institutions, power disparities, and a competitive interest is what scholars have referred to as a "field." Fields can be complex, and the coordination among interests is generally done through a form of governance involving a wide array of laws, regulations, and actors. When at least one of these …

Magma Evolution And Eruptive History Of Three Fingered Jack: A Mafic Composite Volcano In The Central High Cascades Of Oregon, Javaria Aziz

Dissertations and Theses

The central High Cascades graben in Oregon has been a center for mafic volcanism since its initiation. Three Fingered Jack is one of the larger mafic composite cones in the graben, located 20km south of Mount Jefferson. Three Fingered Jack erupted between 142.1 - 150.8ka, based on Ar⁴⁰/Ar³⁹ age dates. This study provides stratigraphic, compositional and petrographic evidence to understand the eruptive history of Three Fingered Jack and the processes involved in generating compositionally diverse basaltic andesites here.

The basaltic andesites of Three Fingered Jack show three compositional trends of magma evolution: 1) enrichment, 2) depletion and …

"Significant Bodily Intrusions": Investigations Into Law Enforcement Phlebotomy, Anne Kathleen Johnson

Dissertations and Theses

This three-paper dissertation explores law enforcement phlebotomy, the ability of law enforcement officers to draw blood. Phlebotomy is both a ubiquitous, invasive diagnostic tool as well as a social site with complex relational dynamics at play between phlebotomist and patient. Through law enforcement phlebotomy, the blood draw is co-opted from the medical field into the policing field, and the normative framework through which it is used changes: whereas medical edicts instruct providers to work with patients through an ethics of care--respecting consent and refusal--policing is not similarly bound, instead operating through a prioritization of security and efficiency. In the articles …

Experiences Of Support And Success For Students Of Color In The Midwifery Educational Setting, Laura Jenson

Dissertations and Theses

The United States spends more on healthcare than any other developed country, yet perinatal health outcomes are among the worst, particularly for Black and Indigenous pregnant women and people. Structural and societal racism has contributed greatly to these inequities, and while a diverse perinatal healthcare workforce has the potential to mitigate the impact of pervasive racism, professions such as nurse-midwifery have evolved over time to be predominately white. The purpose of this study is to explore how students of color experience support and apply personal strategies for success in the midwifery educational setting. A basic qualitative study was done using …

Weak Formulation For Solving Inverse Problems In Reproducing Kernel Hilbert Spaces (With Applications To Learning Dynamical Systems), Victor William Rielly

Dissertations and Theses

We combine numerical and machine learning techniques to present a general framework for solving inverse problems using vector valued reproducing kernel Hilbert spaces in a variational formulation. We present this framework in two papers. In the first paper, we present an original state-of-the-art method derived in the context of our general framework for learning dynamical systems. In the second paper, we generalize the method from our first paper to arrive at the framework for solving inverse problems. Then we apply our general framework to the task of learning dynamical systems. In both papers we consider numerous applications of our methods …

Unremarkable To Remarkable Ai Agent: Exploring Boundaries Of Agent Intervention For Adults With And Without Cognitive Impairment, Mai Lee Chang, Samantha Reig, Alicia (Hyun Jin) Lee, Anna Huang, Hugo Simão, Nara Han, Neeta M. Khanuja, Abdullah Ubed Mohammad Ali, Rebekah Martinez, John Zimmerman, Jodi Forlizzi, Aaron Steinfeld

Computer Science Faculty Publications and Presentations

As the population of older adults increases, there is a growing need for support for them to age in place. This is exacerbated by the growing number of individuals struggling with cognitive decline and shrinking number of youth who provide care for them. Artificially intelligent agents could provide cognitive support to older adults experiencing memory problems, and they could help informal caregivers with coordination tasks. To better understand this possible future, we conducted a speed dating with storyboards study to reveal invisible social boundaries that might keep older adults and their caregivers from accepting and using agents. We found that …

Overt Representation And Subtle Clues A Study Of Queer Book Descriptions In English, Croatian, And Serbian, Rachael Phillips

Book Publishing Final Research Papers

Most commonly, a book description is the first contact one has with the contents of a book. It is the elevator pitch on the back of the book or the Amazon page that tries to sell you your next read among literally millions of competitors. In book publishing terms, a book description is a piece of metadata that follows the book throughout its marketing life. It is usually a one to three paragraph description of the book, including the setting, main characters, and some (spoiler-free) plot summary, but also usually includes themes and tone, comparative titles, and potentially author background …

Glacial-Interglacial And Millennial-Scale Changes In Nitrous Oxide Emissions Pathways And Source Regions, J. A. Menking, J. E. Lee, E. J. Brook, J. Schmitt, L. Soussaintjean, H. Fischer, J. Kaiser, A. Rice

Physics Faculty Publications and Presentations

During the transition from the Last Glacial Maximum (LGM) to the Holocene, the atmospheric N2O mole fraction increased by 80 nmol mol−1. Using ice core measurements of N2O isotopomer ratios, we show that this increase was driven by increases in both nitrification and denitrification, with the relative partitioning between both production pathways depending on the assumed isotopic end‐member source signatures. Similarly, we also attribute a 35 nmol mol−1 N2O mole fraction increase during the Heinrich Stadial 4/Dansgaard Oeschger 8 (HS4/DO8) millennial‐scale event to increases in both N2O production pathways. In contrast, the 25 nmol mol−1 N2O mole fraction decrease during …

The New Normal: A Qualitative Study Exploring The Experiences Of Today's Academic Nursing Faculty, Lisa R. Scott

Despite decades of targeted interventions, the faculty shortage remains a pressing challenge for nursing education and the broader healthcare system. This qualitative study examined the lived experiences of academic nursing faculty navigating dynamic educational and healthcare landscapes. Drawing on semi-structured interviews with 12 full-time, doctorally-prepared faculty members with at least six years of experience, the study explored how participants responded to rapid technological advancements, increasing diversity, the long-term …

When My Intersecting Identities Of Being Racially Oppressed And Privileged Become Blurred: An Autoethnographic Dive Into Unlocking The Polarities Of Who I Am, Susan Acosta

Dissertations and Theses

Freire argued that each person is, at times, both the oppressor and the oppressed. He posited that the path to liberation is increased critical consciousness, problematizing our circumstances, and finding ways to take action. As a person from the global majority (PGM), this autoethnography incorporates my personal narratives, communication with colleagues, photo observations, and professional writings that problematizes and examines ways I have been both complicit in, or have been victimized by, racialized oppression, particularly in educational settings. I've had an increasingly keen sense of awareness toward my own racialized tensions when interacting with individuals, in groups, or with an …

Cuju: The Ancient Chinese Game That Held An Empire Together, Enzo H. Smith

Young Historians Conference

This paper explores how cuju, an ancient sport known as the predecessor of modern football, evolved from the Han to Song dynasties (206 BCE–1368 CE) as a unifying force in imperial China. Calling upon primary sources such as ancient cuju manuals and various art pieces suggests this sport's importance went beyond a leisurely practice. Using academic journals about Chinese history and the development of cuju from different academic fields and, most notably, the FIFA museum’s online exhibit of cuju, the reason cuju had such a strong place of value in Chinese society was apparent. Beginning as a combat exercise in …

Entheogens: The Hallucinogenic Plants That Shaped Religion, Nicolas A. Michaud

Young Historians Conference

Entheogens have played a pivotal role in religious and spiritual practices across diverse cultures, aiding in the pursuit of divine connection and higher consciousness. Evidence suggests that dating as far as back as a million years ago, early human species such as Homo erectus and Homo habilis experimented with hallucinogenic plants like psilocybin mushrooms, introducing the earliest forms of shamanic practices. As societies became more structured, the use of entheogens expanded throughout various parts of society. In ancient Greece, oracles utilized plants like henbane to communicate with the divine, molding military and political policy. During the Middle Ages, Tibetan Buddhism …

Exposing The Truth Behind The Stanford Prison Experiment, Leo Novack

Young Historians Conference

In 1971 Philiip Zimbardo, a Stanford University professor, designed an experiment to study human behaviors in the prison system. He sought to understand the effectiveness of the prison system, however, the experiment ended early due to the ethical concerns toward participants. It is considered one of the most important psychological experiments, not for what it helped reform, but for what it pointed out about the importance of safety for research participants. Calling upon primary sources from participants and the researchers’ findings, as well as secondary sources primarily from psychologists and research ethics, the research reveals that this study was unreliable …

A Crucial Western Foothold: Uyghur-Americans In The Fairfax-D.C. Metro Area, Jake C. Mccauley

Young Historians Conference

Since the 1980s, the Uyghur people of East Turkestan, now known as the Xinjiang Uyghur Autonomous Region, have migrated from their ancestral homeland in China in search of a better life. As an ethnically, linguistically, and religiously distinct group, the Uyghurs face severe oppression, with the Chinese state targeting them economically, socially, and physically. Since 2017, mass internment efforts have escalated, leading to the establishment of labor camps that claim to transition Uyghur labor from agricultural to industrial sectors but also serve as sites of ideological indoctrination, torture, and death. As a result of these human rights violations and other …
