“I Don’T Always See A Future For Me Here”: Oppressive Political Pressures On Lgbtq+ College Students’ Well-Being, Jodi Linley, Olivia M. Copeland, Kathleen J. Buell, Cindy Ann Kilgo, Megan Pendleton, Alex C. Lange, N F. Tennessen

Journal of Queer and Trans Studies in Education

In recent decades, colleges have broadly supported LGBTQ+ students. Now, institutions have shuttered LGBTQ+ initiatives in response to political pressures, with little consideration for the effects on students. This study answers the question, what current policy factors do LGBTQ+ college students describe as affecting their well-being, and in what ways? We analyzed 426 responses from a multi-institution study of LGBTQ+ students. By and large, students feel anxious and fearful as they navigate the current climate. Our analysis illustrated numerous factors, from the President and his administration to states and general emboldened violence, and the real and potential consequences of those …

A Multiple Case Study Exploring The Lived Experiences Of Special Education Teachers Of Students With Intellectual Disabilities, Patrece A. Scott

Doctor of Education Dissertations

Special educators, particularly the teachers of students with intellectual disabilities, remained an understudied group in research. The purpose of this phenomenological qualitative study was to examine how special educators navigated their lived experiences collaborating with three key stakeholder groups: parents, general education teachers, and administrators, particularly working with students with intellectual disabilities. Specifically, this study examined how special educators experienced collaboration with those stakeholder groups through the framework of McClelland's (1961) Theory of Needs. The study involved two semi-structured interviews with each of the 12 participants, all of whom were special educators at the middle or high school level. These …

Distillation Laundering: Regulatory Arbitrage And A Potential Beijing Effect In Ai, Laura Edelson, Filippo Lancieri

Georgetown Law Faculty Publications and Other Works

This essay introduces distillation laundering, a new form of regulatory arbitrage. Distillation, a technique for training large language models based on the outputs of other models instead of from scratch, is generally prohibited by the terms of service of closed-weight frontier models. However, it is economically efficient and has been key to the success of the cheap, distilled (largely Chinese) open-weight models, which have reshaped the global political economy of AI regulation. US companies have now begun to re-import the effects of distillation through various means—a process we call distillation laundering. We also discuss how attempts to lobby these models …

Adults With Dyslexia: Experiences Accessing And Using Reading Strategies And Assistive Technology, Brenda Rosalie King

Graduate Student Theses, Dissertations, & Professional Papers

Dyslexia is a specific learning disorder of neurobiological origin characterized by persistent difficulties with accurate and/or fluent reading, word recognition, spelling, and decoding. Although dyslexia is widely recognized as a lifelong learning difference, the majority of research has historically focused on children and adolescents, with less attention given to adult experiences. The purpose of this study was to explore how adults with dyslexia access and use reading strategies and assistive technologies to support reading comprehension and independence across contexts. The study also examined barriers and supports influencing access to these tools, as well as the emotional experiences associated with their …

Advancing Understanding Of Lived Experience Of Unhoused People To Reduce Social Stigma And Promote Community Health: A Theoretically-Guided Photovoice Study, B-Rad Stephen Applegate

Graduate Student Theses, Dissertations, & Professional Papers

Homelessness is a persistent public health challenge shaped by structural inequities, stigma, and exclusion from social and health systems. Community-Based Participatory Research (CBPR) has increasingly been used to center the knowledge of people who are unhoused, yet limited attention has been given to the theoretical frameworks guiding this work across disciplines. The purpose of this dissertation was to examine theories and methods used in CBPR with unhoused populations and to explore the extension of Margaret Newman’s Theory of Health as Expanding Consciousness from a nursing-focused theory to a public health framework for understanding lived experience.

Using a scoping review methodology …

Flight Control And Costs In Unsteady And Turbulent Airflows In Ringneck Doves (Streptopelia Risoria), Rémy Alexandre Delplanche

Graduate Student Theses, Dissertations, & Professional Papers

The aerosphere is a highly dynamic environment where turbulence (irregular, chaotic changes in airflow velocity) and unsteady airflows (variations in flow velocity with time at a given spatial point, e.g. gusts) are ubiquitous [1,2]. These airflows are known to perturb man-made aircraft [3,4], and are thus expected to challenge biological fliers such as birds. However, birds display remarkable flight control in turbulent and gusty conditions, suggesting that they have evolved mechanisms to resist aerial perturbations. This in-flight stability is broadly attributed to wing morphing, the capacity for wing shape and orientation to be altered during flight, yet how morphable wings …

Evolution Of A Nitrogen-Fixing Endosymbiont And Integration With Its Diatom Host, Heidi Elizabeth Abresch

Graduate Student Theses, Dissertations, & Professional Papers

Endosymbiosis, where one cell lives inside of a different cell, is ubiquitous in nature and has enormous impacts on the ecology and evolution of both the host and the endosymbiont [1, 2]. These relationships exist along a continuum ranging from facultative—where both partners are able to live independently—to completely obligate—where partners can only survive in the presence of the other. The most famous examples being the chloroplast and mitochondrion [3]. After hundreds of millions or even billions of years of coevolution, highly-integrated endosymbionts are coordinated with the host on the genetic, metabolic, and cellular levels, but we do not understand …

Á’Po’Taki Iiyika’Kimaa Work/Try Hard For Such A Time As This, Misamsai’Piaakíí Longtime Charging Woman Kimberly Lynn Paul

Graduate Student Theses, Dissertations, & Professional Papers

This body of work adds to a recent shift in the academic landscape, valuing interdisciplinary research and Indigenous worldview. Predominant is the reversal of extractive research norms within Indigenous populations and the biosystems they steward, instead claiming Piikani (Blackfeet) led community-needs-based research valuing Indigenous data sovereignty, research methodologies, ethics, equity, and Indigenous empowerment. This research proffers requisite historical information providing the ‘why’ context, followed by three of the author’s studies: in toxic dumping, food sovereignty, and Piikani well-being. Under an environmental justice framework, the first study presents a cursory investigation of decades-long illicit toxic waste disposal reports linked to observed …

Hidden Wounds: Exploring Moral Injury In Childhood Exposure To Domestic Violence, Megan Elizabeth Denny

Graduate Student Theses, Dissertations, & Professional Papers

The profound impacts of Childhood Exposure to Domestic Violence (CEDV) have been documented extensively, revealing long-term psychological effects such as the potential development of post-traumatic stress disorder (PTSD) and increased likelihood of future victimization or perpetration of violence. Yet, the concept of moral injury (MI) traditionally explored in military and healthcare contexts, remains significantly underexplored in populations exposed to CEDV. This study examines the relevance of MI among individuals who experienced domestic violence (DV) during their youth. The research focused on two primary aims: (1) to describe the level and variability of moral injury-related distress among adults with histories of …

The Forensic Implications Of Hydrochloric Acid (Hcl) Exposure On Dna Preservation In Human Teeth, Shaelyn Lee Zimmerman

Graduate Student Theses, Dissertations, & Professional Papers

Identity is a human right, and forensic anthropological methods are often aimed at returning identity to decedents. Three main pathways are used for the identification of human remains: fingerprints, dental records, and DNA analysis. Identification efforts may be hindered when perpetrators attempt to obscure the victim’s identity. In cases where corrosive substances, such as hydrochloric acid (HCl) are used, dental comparison and fingerprinting often fail and genetic analysis becomes the best chance of achieving personal identification.

Previous studies have shown teeth are an excellent source of DNA. Large, multi-rooted teeth, such as molars, are often preferred because they contain the …

“An Extremely Dangerous Institution:” The Cultures And Controversy Of Public Social Dances In Montana, 1900-1930, Danielle Allison Brown

Graduate Student Theses, Dissertations, & Professional Papers

This paper explores public social dances east of the Continental Divide in Montana from 1900 to 1930. Rural social dances in schoolhouses and urban dances in dance halls created two different dance cultures. The relaxed nature of rural dances preserved the traditional values of nineteenth-century social dances, which reinforced community and family ties. Urban dances reflected the modern fads of the roaring twenties and challenged traditional values with sexual suggestiveness. Progressive Era moral reformers concerned about the possibility that social dance promoted illicit sexuality participated in an anti-dance movement and pushed for regulations of social dances. The anti-dance movement in …

Unmuted: An Augmentative And Alternative Communication User’S Experience In Accessing And Engaging In Mental Health Care, Kanbi Faith Knippling

Graduate Student Theses, Dissertations, & Professional Papers

Communication accessibility is a critical yet underexamined factor influencing access to and engagement in mental health care for individuals who use augmentative and alternative communication (AAC). Existing literature suggests that AAC users experience significant barriers to obtaining communication-accessible mental health services, including limited provider preparation, communication-related assumptions, and broader structural inequities. Despite growing recognition of these concerns, little research has explored how AAC users experience and navigate mental health counseling or how communication accessibility shapes participation in care.

This single-case study explored communication accessibility within the context of an adult AAC users' experiences accessing and engaging in mental health counseling. …

A Psychogeography Of The Lower Colorado River Basin, Arren L. Kimbel-Sannit

Graduate Student Theses, Dissertations, & Professional Papers

Dried-up canals. Superheated strip malls. Proliferating data centers. Infinite appetite for growth despite its apparent circumstances. Arizona may well be the state of the American future. This multi-genre series of essays from Arren Kimbel-Sannit offers a personal, political-economic and ecological critique of growth and accumulation in Arizona — from the perspective of someone who grew up in its suburban expanses, reported on its politics, and long sought to clarify his relationship with home.

Building Trust Through Partnership: A Community Advisory Board Self-Evaluation Within A Blackfeet Nation Community-Based Participatory Research Collaboration, Lauren Dupuis

Graduate Student Theses, Dissertations, & Professional Papers

Community Advisory Boards (CABs) are frequently used within community-based participatory research (CBPR) to promote community engagement, shared decision-making, and cultural responsiveness. Although CABs are widely utilized in Indigenous research partnerships, relatively few studies have evaluated CAB function from the perspectives of Indigenous community members. Our study describes the development of a CAB established through a collaborative partnership between the University of Montana and the Blackfeet Nation and evaluates the quality and impact of the partnership from the perspectives of CAB members. We conducted a mixed-methods partnership self-evaluation with members of a CAB supporting an Indigenous healthcare research initiative. Three of …

Growing Agroecology: Two Case Studies From The U.S. Student Farm Movement, Amelia B. Armstrong

Graduate Student Theses, Dissertations, & Professional Papers

Scholars and activists identify agroecology as a crucial science, practice, and movement to move towards more just, equitable, and sustainable agriculture and food systems. Yet, the exploitative industrial food system, that deepens inequalities like food insecurity (Clapp et al., 2025), reduces farmer autonomy (Rotz, 2015), and contributes to increased carbon emissions (Lin et al., 2011) and biodiversity decline (Rotz, 2015), still dominates. Understanding and mobilizing the different spaces that teach agroecology, then, is a crucial step in challenging the dominant industrial food system. Agroecology education in university settings is an important domain to investigate as potential contributors to this movement, …

"More Boldly I Shall Go:" Jacobites, Hanoverians, And The Fabrication Of Nostalgia, 1745-1766, Jacob Louis Shropshire

Graduate Student Theses, Dissertations, & Professional Papers

This study investigates how Jacobites and Hanoverians constructed competing forms of nostalgia, identity, and political meaning in the decades after the rebellion of 1745. Although the defeat of Prince Charles Edward Stuart at Culloden ended any realistic hope of a Stuart restoration, it sparked a cultural struggle in which both supporters and opponents of the Stuarts depicted the Highlander as a symbol of heroic resistance or barbarism. A psychic struggle emerged as a result, and the Highlander became beloved by Jacobites and loathed by Hanoverians. These representations circulated through paintings, engravings, clothing, glassware, newspapers, pamphlets, and verse, which became central …

Thistlebloom Moondog, Gary W. Jensen

Graduate Student Theses, Dissertations, & Professional Papers

An aging grieving artist decides to write a memoir as part of a self-healing process, using samples of song lyrics from his extensive collection of original Americana songs as narrative prompts.  Steeped in wanderlust, aspiration, paradox and dysfunction, his is a tale of vexing sub-clinical troubles rooted in the mire of developmental and religious trauma.

Illusions Of Fairness And Sacrifice, Brady Schwertfeger

Graduate Student Theses, Dissertations, & Professional Papers

The American West is a shifting landscape. An incongruous expanse of isolation and urbanity, wilderness and extraction, wealth and welfare, clear water and fire. Fifteen years ago, I moved to my mother’s ancestral homeland of Montana, and have been here ever since. Before that, I was born and raised in Texas, both the West and the South (and often something else entirely), depending on who you ask. My experiences in this region have shaped me indelibly, and have inspired this collection of essays built around culture, politics, and justice in the West. “Pinedale, Wyoming” considers the musician as itinerant wanderer …

The Experience Of A Single Parent Participating In Child-Parent Relationship Therapy: An Instrumental Single-Case Study, Matthew Nicholas Schramm

Graduate Student Theses, Dissertations, & Professional Papers

Traditional family structures in the United States have shifted significantly, with single-parent households facing systemic barriers that increase parental stress and strain the parent-child relationship. As this bond is critical for healthy child development, accessible mental health support is essential for these families (Parache et al., 2023).

Child Parent Relationship Therapy (CPRT), a ten-week evidence-based program, strengthens this bond by training caregivers to use play as a therapeutic tool (Landreth & Bratton, 2020). This instrumental single case study (Stake, 1995) examined one single-parent's experience of CPRT delivered in a condensed four-week telehealth format, addressing the limited representation of single-parent households …

Evaluating Multi-Year Transferability Of Single- And Multi-Class Machine Learning For Remote Monitoring Of Beaver-Engineered Landscapes, Harris J. Sloan

Graduate Student Theses, Dissertations, & Professional Papers

Long-term satellite image archives enable ecological monitoring at large scales, but manual extraction of fine-grained features (e.g., beaver dams) remains time-consuming. Machine learning models may automate these tasks, but their temporal transferability for multiannual monitoring is still poorly resolved.

We evaluated the performance of two complementary neural-network frameworks across a 100,000-hectare watershed in Montana USA, using a decade of satellite imagery (2014-2024): (i) a single-class ResNet-50 beaver dam detector, and (ii) a multi-class ResU-Net landcover classifier.

In 2024, the dam detector identified 352 of 404 mapped dams, achieving balanced accuracy = 93.6%, precision = 79.8%, recall = 87.1%, F1 = …

Feral Horses And Native Ungulates: Evaluating The Potential For Competition In Predator–Prey Communities Of Alberta’S Upper Foothills, Birch Gano

Graduate Student Theses, Dissertations, & Professional Papers

Feral herbivores are expanding in range and numbers globally, yet their community-level effects in ecosystems are poorly resolved. We evaluated whether feral horses reshape predator–prey–vegetation dynamics in Alberta’s Upper Foothills, Canada, through two pathways; i) potential exploitative competition for forage and ii) apparent competition via shared predators. We combined fecal DNA metabarcoding with remote wildlife cameras to quantify diets, spatiotemporal co-occurrence, and the role of horses in carnivore diet. We analyzed 241 ungulate scats (feral horses, elk, bighorn sheep, cattle, moose, and deer), 96 combined camera-years at 23 sites, and 190 carnivore scats (wolves, cougars, coyotes, bears) from 2023–2025. The …

Preserving Their Institutions While Living Among Strangers: Heritage Adaptation Exhibited Within Missoula, Montana’S Chinese Community, 1860 – 1940, Sophia Hattie Etier

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation by publication reconstructs the history, cultural institutions, and adaptive strategies of Missoula, Montana’s Chinese community between 1860 and 1940, arguing that the population underwent a long-term, multi-generational process of heritage adaptation shaped by exclusion, isolation, and demographic decline. Drawing from Kalervo Oberg’s 1954 culture shock model, the study proposes a new theoretical framework—heritage shock—that extends the four-stage adjustment process from individuals to cultural communities. This model demonstrates how diasporic populations collectively navigate periods of arrival, crisis, adjustment, and long-term adaptation when confronted with sustained external pressures. Using an interdisciplinary methodology that integrates archival research, archaeological and faunal analysis, …

Cryptic Mechanisms Of Post-Fire Nitrogen Recovery In Northern Conifer Forests, Robert Edward Heumann

Graduate Student Theses, Dissertations, & Professional Papers

In recent decades, northern conifer forests have experienced larger, more frequent and more intense wildfires. Severe, stand-replacing wildfire substantially reduces forest nitrogen (N) stocks, a critical nutrient that often limits net primary productivity on land. Continued increases in wildfire activity may exacerbate forest N limitation in the future. Yet, while research shows N stocks in northern conifer forests recover following severe wildfire, the processes that contribute to rapid increases in N during post-fire regeneration are unclear. Atmospheric deposition of N and known sources of biological N fixation cannot explain the observed post-fire N accumulations. This paradox raises the question: How …

Effectiveness Of Behavioral Cough Suppression Therapy In A Closed Enrollment Group Telehealth Delivery Model And Comparison To A Rolling Enrollment, Kinsey Louise Roberts

Graduate Student Theses, Dissertations, & Professional Papers

Background:

Refractory chronic cough (RCC) is a subtype of chronic cough (CC) that persists

despite guideline-based treatment and can negatively affect quality of life. Behavioral cough

suppression therapy (BCST), typically delivered by speech-language pathologists (SLPs), is an

effective treatment for RCC. However, access to BCST remains limited due to geographic

barriers and a shortage of trained providers. Group-based telehealth may help expand access to

treatment. This study evaluated the effectiveness of BCST delivered via telehealth using

a closed enrollment group model and compared outcomes to a rolling enrollment group model.

Methods:

In this prospective sequential cohort study 32 participants attended …
