Searching For Nooks And Crannies: Geometric And Mechanistic Perspectives On Transformer Language Model Interpretability, Anna Marbut

Graduate Student Theses, Dissertations, & Professional Papers

Large language models (LLMs) have demonstrated remarkable linguistic capabilities, but the internal mechanisms driving their performance and behavior remain poorly understood. This dissertation investigates the interpretability of transformer-based language models from two complementary perspectives: the geometric organization of model internals in encoder-only models, and the mechanisms underlying safety behavior in decoder-only generative models.

In Part I, we address the challenge of measuring geometric properties in high-dimensional latent spaces, proposing and evaluating alternative measures of data spread that improve upon commonly used metrics. We then apply these measures alongside quantization-based metrics to examine the relationship between latent space geometry and downstream …

The Birth Of Afghanistan: From Ancient Persia To A Modern-Day Multiethnic And Linguistic Country, Tyler A. Worm

Graduate Student Theses, Dissertations, & Professional Papers

This thesis offers a comprehensive historical analysis of the formation and evolution of Afghan identity from antiquity through the early medieval period, emphasizing the region’s role as a dynamic crossroads of civilizations. It traces the origins of Afghan populations to Indo-Iranian pastoralist migrations and examines the successive influence of major imperial formations, including the Median and Achaemenid Persian empires, the conquests of Alexander and the Seleucid period, and the rise of the Kushan, Parthian, and Sasanian states. Through this longue durée approach, the study demonstrates how Afghanistan’s geographic position facilitated continuous cultural interaction, economic exchange, and political contestation, producing a …

Between Care And Protection: Constraints On Political Authority In Kamala Harris's 2024 Presidential Campaign, Marissa Barbara Pax

Graduate Student Theses, Dissertations, & Professional Papers

Competing expectations about strength, care, and protection shape how presidential leadership and authority are constructed in contemporary U.S. politics, particularly for members of marginalized communities. This thesis examines Kamala Harris’s 2024 presidential campaign as a case study to explore how candidates negotiate competing understandings of political authority through appeals to Lakoff’s (2002, 2008) Strict Father Morality and the Nurturant Parent Morality. An analysis of her campaign reveals that Harris repeatedly appeals to both moral frameworks, constructing authority through empathy, mutual responsibility, and care while also emphasizing threat identification, protection, discipline, and moral strength. Although Harris successfully mobilizes the rhetorical resources …

High Algal Biomass Is Decoupled From Metabolism In The Gallatin River, Cora Mae Steinbach

Graduate Student Theses, Dissertations, & Professional Papers

Assessing eutrophication in rivers is difficult compared to lakes and coastal waters, because most algal biomass occurs on the riverbed and flows interact and co-vary with production (Biggs and Close, 1989; Bernhardt et al., 2018). Riverine eutrophication is typically assessed using algal biomass and water column nutrients (U.S. Environmental Protection Agency, 2000), but biomass is highly variable and labor-intensive to measure, while nutrient concentrations often underestimate enrichment due to rapid biological uptake (Dodds and Smith, 2016). Reach-scale river metabolism can help evaluate long-term functional change in rivers recovering from nutrient enrichment (Arroita et al., 2019; Jankowski et al., 2021; Diamond …

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 …

To Flea Or Not To Flea: Abiotic And Biotic Factors Driving Flea Parasitism On Wild Deer Mice, Parker Todd, Angela Luis, Mike Kinsella

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Deer mice (Peromyscus maniculatus) are an abundant North American rodent and the primary reservoir for Sin Nombre virus (SNV), a hantavirus with a 30-40% case fatality rate in humans. While ectoparasites, such as fleas, are not considered vectors of SNV, their bites may indirectly affect the transmission of SNV by impacting host condition or immune function. These impacts could potentially lead to an increase in host susceptibility and/or an increase in viral shedding, yet there is still little knowledge on what influences flea parasitism on deer mice in western Montana. This study looks to examine how mouse sex, …

Perceptions And Metaperceptions Of Bison In The West, Riley Rush Comstock

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Effective coexistence between wildlife populations and the people that live with them requires an understanding of how people feel toward the species and their management. Bison occupy a unique place in conservation history and management. Once extirpated across nearly all of their range and only recently introduced to areas outside of large tracts of federal land, they are now a jurisdictionally challenged species, with varying management paradigms across a patchwork of landowners and managers. Recent research has shown how activating different social identities can distort people’s attitudes toward species. Here, I explore whether activating urban and rural identities distorts people’s …

Probing Proficiency-Related Neural Representations With Pca And Ica, Onila R. Narayana Mudalige Don

Graduate Student Theses, Dissertations, & Professional Papers

How proficiency-related information is represented in task fMRI depends not only on the data themselves, but on the representational lens used to summarize them. This thesis examines second-language (L2) proficiency as a problem of representational organization rather than as a simple classification exercise. Using task fMRI from adult language learners performing semantic animacy judgments in their native language (L1) and second language (L2), I derive shared low-dimensional network representations with principal component analysis (PCA) and independent component analysis (ICA), then evaluate those representations under matched leakage-controlled decoding pipelines.

Across analyses, the central comparison is between representational frameworks rather than between …

Velocity Based Training In Athletic Development, Ross Martin Sangalang

Graduate Student Theses, Dissertations, & Professional Papers

The foundation of high-level sport performance is the ability to produce and express force rapidly across the task-specific temporal demands of sport. Traditional percentage-based prescription methods have long been used to develop hypertrophy, maximal strength, and power; however, fixed %1RM prescriptions fail to account for daily undulations in athlete readiness, accumulated fatigue, and changes in neuromuscular capacity. Velocity based training (VBT) offers a practical framework to regulate training through measurement of concentric velocity, allowing coaches to more accurately prescribe loads, stringently monitor repetition quality, and precisely regulate fatigue. This review discusses the neuromuscular qualities underpinning success in athletic endeavors, limitations …

Expectations In The Preservation Of Dna And Bacterial Organisms In Differential Montana Burials, Kaylee M. Hinds

Graduate Student Theses, Dissertations, & Professional Papers

This study investigates patterns of decomposition and biomolecular preservation in domestic pig (Sus scrofa domesticus) proxies under varying burial conditions in a cold, seasonal climate. Conducted at the Lubrecht Experimental Forest in western Montana, the project aims to evaluate DNA degradation, microbial activity, and environmental influences across shallow, deep, surface, and secondary burial contexts. Three pigs were placed in distinct burial treatments (surface exposure, partial burial, and full burial), with a fourth site later added following bear disturbance and carcass relocation. Environmental monitoring included temperature, and soil sampling before and throughout the decomposition process. Systematic sampling of bone, soft tissue, …

Skeletal Dna Mapping Of The Post-Cranial Skeleton For The Identification Of Human Remains In A Modern Forensic Context, Mykala Denise Ward

Graduate Student Theses, Dissertations, & Professional Papers

Human identification is a central goal of forensic anthropology and forensic molecular anthropology, particularly when remains are skeletonized, fragmented, degraded, or otherwise visually unidentifiable. Although skeletal elements such as teeth, the petrous portion of the temporal bone, and major long bones are commonly prioritized for DNA sampling, they are not always available, intact, or suitable for destructive analysis. This dissertation evaluates DNA preservation across the post-cranial skeleton to determine whether anatomical location, biological sex, and age-at-death influence DNA quantity and downstream forensic genetic success.

Surface cortical bone samples were collected from predetermined anatomical locations across four modern skeletonized individuals. DNA …

Superintendent Accountability In High Achieving School Districts: A Qualitative Multiple Case Study In The State Of Washington, Kristin Lind Jacobs

Graduate Student Theses, Dissertations, & Professional Papers

The primary goal of a school district is to promote and support student academic achievement. Superintendents of public school districts across the United States should therefore be held accountable for student performance within their districts. Establishing a successful public school district requires interconnected relationships among the superintendent, the school board, accountability structures, and evaluation processes.

The purpose of this qualitative multiple case study was to understand how superintendent accountability, in regard to student achievement, was conducted and accomplished by school boards who believe they hold the superintendent accountable for student learning. This study focused on school boards governing high-achieving school …

Winding Roads: A Qualitative Phenomenological Study Of Female Educational Leadership, Nicole Casper

Graduate Student Theses, Dissertations, & Professional Papers

The experiences of female superintendents were examined in this study to provide insight into the commonalities in their leadership journeys within public school organizations. A phenomenological, qualitative approach, aligned with Moustakas’s (1994) framework, was used to explore participants’ shared experiences. Comprehensive interviews were conducted with 17 female superintendents serving during the 2022–2023, 2023–2024, and/or 2024–2025 academic years in the states of Idaho, Montana, Oregon, and Washington. Through phenomenological reduction, three overarching commonalities emerged: (a) barriers, (b) challenges, and (c) supporting factors. The findings illuminate how organizational, societal, and gendered influences interact to shape female leadership advancement toward assistant superintendent or …

Beyond Words: The Horse-Human Encounter In Equine-Assisted Psychotherapy For Residential Substance Use Treatment, Leah Finch Lungren

Graduate Student Theses, Dissertations, & Professional Papers

Equine-assisted psychotherapy (EAP) has emerged as a promising experiential therapeutic intervention, yet the lived experience of adults participating in EAP within residential substance use disorder (SUD) treatment settings remains underexplored. This hermeneutic phenomenological study examined the lived experience of 12 adults who participated in EAP groups during residential SUD treatment across three treatment facilities in the United States. The primary research question was: What is the lived experience of participating in EAP for adults in residential SUD treatment? Data was collected through semi-structured interviews and analyzed through iterative hermeneutic interpretation guided by van Manen’s (1990) existential framework.

Six themes emerged …

Integrating Hippotherapy Into Interprofessional Aphasia Rehabilitation: A Feasibility Pilot Study, Bethany H. Wenger

Graduate Student Theses, Dissertations, & Professional Papers

Background and Significance: Stroke remains a leading cause of disability in the United States, affecting over 2.5 million individuals annually. Stroke-related motor and communication deficits often co-occur, increasing challenges for recovery, increasing social isolation, depression, and dependency. Hippotherapy has emerged as a novel treatment approach for neurorehabilitation; however, its application within interprofessional models for individuals with stroke-related motor and communication impairments remains underexplored. This study examines the feasibility, fidelity, and acceptability of an interprofessional intervention using hippotherapy for adults with chronic post-stroke aphasia, the purpose of which is to generate methodological guidance for future controlled trials.

Methods: A non-randomized, single-group …

An Exploratory Analysis Of The Role Of Sex In Load Carriage, Rachel E. Perez, Dustin R. Slivka, Brent C. Ruby

Graduate Student Theses, Dissertations, & Professional Papers

Axially loaded weight may impose a metabolic demand equivalent to that of fat mass (FM) during load carriage. Males (M) typically have a lower body fat percentage than females (F), resulting in metabolic demand differences during load carriage that may be mitigated by accounting for FM in pack loads. PURPOSE: To determine whether normalizing pack load to FM equalizes metabolic cost across sexes during load carriage. METHODS: Twenty-eight participants (14M, 23 ± 5 y, 1.81 ± 0.07 m, 78.7 ± 10.0 kg, 12.7 ± 5.4% body fat, VO₂peak 4.18 ± 0.54 L·min^-1; 14F, 22 ± 4 …

Bridging The Gap: Evaluating Gnss-Derived Total Water Storage As A Groundwater Monitoring Tool In The Colorado River Basin, Michelle Lee Barton

Graduate Student Theses, Dissertations, & Professional Papers

Groundwater resources in the Colorado River Basin are critically stressed yet remain under-monitored and under-regulated, creating urgent need for reliable, continuous observations at multiple spatial scales. This study evaluates the performance of the University of Montana Global Navigation Satellite Systems (GNSS) terrestrial water storage dataset as a tool for bridging groundwater monitoring gaps across the Upper and Lower Colorado River Basins between 2006 and 2024.

Characterizing Regional Human Necromicrobiome Communities In A Semi-Arid Desert To Inform Postmortem Interval (Pmi) Estimation, Georgia Rane Swelstad

Graduate Student Theses, Dissertations, & Professional Papers

Accurate estimation of the postmortem interval (PMI) remains challenging in forensic anthropology, particularly in arid and high-elevation environments where decomposition processes and insect activity are highly variable. Postmortem microbial succession has emerged as a promising alternative framework for PMI estimation. However, the effects of climate and elevation on microbial decomposition dynamics remain insufficiently characterized.

This study examines skin-associated microbial succession in human remains decomposing at the Forensic Investigation Research Station (FIRS) in western Colorado, a semi-arid, high-elevation environment. Microbial samples collected from five anatomical sites during the early postmortem interval are analyzed using 16S ribosomal RNA (rRNA) gene sequencing, and …

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. …

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 = …

Cormac’S Court: Knights Without God In A Savage Land; Or, Chivalry And Existentialism In Cormac Mccarthy’S The Road, Zoë Margaret Metelerkamp

Graduate Student Theses, Dissertations, & Professional Papers

Cormac McCarthy scholars have examined the influence of romantic grail quest literature and existential philosophy on McCarthy’s oeuvre, but they have treated these subjects independently of each other. This thesis offers a novel exploration of McCarthy’s use of these specific philosophical and literary precedents by focusing on the ways The Road unifies medieval literary principles in Chretien’s Perceval with the existential chivalry Søren Kierkegaard extrapolates in Fear and Trembling.
