Integrating Perspectives Of People With Aphasia: A Holistic Approach To Community Aphasia Groups Within An Intensive Comprehensive Aphasia Program, Mckinlee A. Mihelish

Graduate Student Theses, Dissertations, & Professional Papers

Introduction: People with aphasia (PWA) experience chronic communication deficits that impact daily life. Community Aphasia Groups (CAGs) are commonly used to address these challenges and have demonstrated psychosocial and communicative benefits; however, they lack standardized structure and are implemented with variability across settings. Additionally, much of the existing research focuses on group-level outcomes rather than participant-driven priorities, limiting clinicians’ ability to tailor interventions. This study examined what PWA want from CAG participation and how these priorities may change over time.

Methods: This quantitative study investigated priority changes among PWA participating in a CAG within a summer 2025 Intensive Comprehensive Aphasia …

Embodied Women’S Health In The Pacific: Biocultural Pathways Of Hormones, Immunity, And Reproduction, Courtney Callidora Manthey

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation examines women’s health through a biocultural framework that integrates biological anthropology, medical anthropology, and public health, with a central focus on the Pacific. It advances embodiment theory as a unifying approach for understanding how lived experience becomes biologically incorporated across the life course, shaping reproductive, endocrine, and immune outcomes. Grounded in research in Sāmoa and situated within broader comparative contexts in the United States and Amazonian populations, this work argues that women’s health cannot be fully understood through biomedical indicators alone, but must instead be interpreted within historically, culturally, and environmentally embedded Pacific contexts and beyond. The dissertation …

Lake As Body: Ecofeminism And Animacy At The Great Salt Lake, Shae Barber

Graduate Student Theses, Dissertations, & Professional Papers

Water shapes cultural, social, and ecological systems. Yet, dominant economic, political, and academic frameworks often treat water as a backdrop or passive resource, ignoring it as an active participant in meaning-making and relationship-building. Viewing water as “nonliving” obscures how it participates in and co-creates relationships, limiting understanding about impacts of and responses to climate change and environmental degradation.

This thesis takes a mixed-methods and participatory approach including semi-structured interview, photovoice, and participatory mapping to examine relational practices between environmental advocates and the Great Salt Lake, a desiccating saline lake in Utah, U.S. As the lake continues to decline, dominant Western …

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 …

Learning In The Wild: A Discourse Analysis Of Literacy Practices And Educational Outcomes In Montana’S Youth Climate Activism, Tyler Moore

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines youth climate activism in Montana as a site of literacy practice, civic learning, and critical climate engagement. Focusing on the University of Montana Climate Response Club, the study asks how youth climate activists use literacy practices to interpret climate issues and participate in civic action, and how those practices reflect elements of critical climate literacy. The study defines critical climate literacy as a set of socially situated practices through which young people read, interpret, question, and respond to climate change as both an environmental issue and a civic problem shaped by power. Rather than treating climate literacy …

Legal Semiotics, Political Ontology, & Merging Chronotopes Of Identity Through The Federation Of Aboriginal Nations Of The Americas, Kevin T. Inglesby

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation studies the concept of self-determination related to a confederation known as the Federation of Aboriginal Nations of the Americas. It addresses three main questions: How does FANA represent an institution of legal cooperation? In what ways does cultural capital become reproduced? And what are key principles for the Federations’ code of unity? Self-determination is a core principle of international law and may be identified through treaties and social conventions like Wunnandry. The study explores an interdisciplinary approach to American Indian selfdetermination through a focus on applied anthropology, cultural heritage, and Peircean legal semiotics to problematize some historical approaches …

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 …

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, …

Continental Violence And The "Oregon Question": George Frederick Ruxton And The Nineteenth-Century Pacific Northwest, Rory Orion Johnson

Graduate Student Theses, Dissertations, & Professional Papers

This paper builds on recent efforts to depict Indigenous polities across North America in their international relations with European and Euro-American colonists and their centralized governments. It examines George Frederick Ruxton, a private English citizen and former army lieutenant, as he developed his response to the U.S.-British Oregon dispute while living in London in early 1846. He concluded that continental warfare was imminent and took overt steps to influence British policy, which he believed could halt U.S. expansion and definitively resolve the “Oregon Question.”

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 …

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 …

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. …

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 …

"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 …

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 …

Describing And Understanding The Use Of Coaches For Eating Disorder Recovery: A Mixed Methods Study, Taylor E. Penwell

Graduate Student Theses, Dissertations, & Professional Papers

Individuals with eating disorders (EDs) experience high rates of relapse and delays in accessing treatment. Considering these factors, individuals with EDs may seek out non-traditional support, such as coaching services (e.g., an unlicensed individual providing support). However, there is currently no research on individuals with EDs’ experiences with using coaching services for ED recovery. The current study aimed to a) describe who is utilizing coaching support, b) describe coaching services received, c) evaluate the motivations for seeking coach support, and d) evaluate the perceived impact of coach support on an individual’s ED recovery. Participants included 86 adults with a self-reported …

Seahorsedad: A Study Of Metaphors In Transmasculine Birther’S Instagram Posts, Alexa Anne Runnion

Graduate Student Theses, Dissertations, & Professional Papers

Dominant notions of pregnancy frame gestation as a solely female process. However, the experiences of transmasculine birthers challenge this assumption, demonstrating that pregnancy is not inherently tied to womanhood but is instead shaped by social and cultural narratives and representations. This paper explores the unique pregnancy and parental exercises of transmasculine birthers by examining public social media posts under the hashtag #seahorsedad on Instagram. Utilizing metaphorical criticism, I aim to uncover how transmasculine birthers, known within the community as “seahorse dads,” both uphold and resist traditional notions of gender, pregnancy, and parenting through a combination of textual and visual metaphor. …

Predicting Language And Literacy Success In Children With And Without Developmental Language Disorder, Melissa Catherine Phelan

Graduate Student Theses, Dissertations, & Professional Papers

The purpose of this study was to investigate the roles of phonological, orthographic, and morphological awareness in predicting language and literacy success for children with developmental language disorder (DLD), DLD with dyslexia, and typically developing (TD) children. DLD, a prevalent yet underdiagnosed condition, is associated with significant psychosocial and academic challenges, including a roughly 50% likelihood of developing dyslexia. Current identification systems rely on inconsistent parent/teacher referrals, which miss approximately 60% of children with DLD and over 33% with dyslexia, limiting access to effective interventions. This study longitudinally examines whether kindergarten screenings of three metalinguistic skills—phonological, orthographic, and morphological awareness—predict …

Designing A Behavior-Supportive Literacy Block Using Ufli Phonics For First Grade Students With Behavioral Challenges, Julia Lynne Pugh

Graduate Student Theses, Dissertations, & Professional Papers

Students with behavioral challenges tend to struggle while engaging with structured academic instruction, particularly in foundational literacy blocks. In fact, in 2021, it was reported that 27.7% of children aged 3-17 struggle with a mental, behavioral, or developmental disorder. (Leeb et al., 2024) While programs such as UFLI (University of Florida Literacy Institute) offer highly effective phonics instruction, these programs typically lack embedded support for individuals struggling with self-regulation, attention, and task persistence. As a result, these students are presented with a higher risk of falling behind in their reading skills. In this project, the author aims to develop a …

Authenticity Can Be Costly: Understanding School Belonging Among Latine Immigrant High School Students, Deborah A. Ith

Graduate Student Theses, Dissertations, & Professional Papers

School belonging is strongly associated with positive outcomes, including overall wellness and higher educational attainment. These outcomes can have lasting impacts on the lives of students. The construct of school belonging is defined as the degree to which a student feels accepted, supported, valued, and comfortable expressing themselves authentically within the school community. Students from culturally and linguistically diverse backgrounds, especially recent immigrants, often have experiences within the school setting that interfere with the development of a strong sense of school belonging. Unfortunately, much of the prior research on school belonging has relied on survey data, correlational studies, or teacher …

Echoes Of Heritage: Understanding The Impact Of Subtractive Bilingualism On Emotional Well-Being And Bicultural Identity In First- And Second-Generation Immigrants, Anna Reszewicz

Graduate Student Theses, Dissertations, & Professional Papers

The effects of emotional well-being and cultural identity have been widely examined, yet little research has examined these outcomes among subtractive bilinguals. This study aimed to fill the gap in the literature by exploring the relationship between emotional well-being and bicultural identity among first- and second-generation immigrants in the United States who were identified as subtractive bilinguals and non-subtractive bilinguals. Subtractive bilinguals are defined as individuals who learn a second language (L2) while experiencing a decline in proficiency or usage of their heritage language (L1). Using self-report measures, 170 participants were recruited and completed an eligibility survey that included the …

Counselor Educators’ Understanding Of Ableism: A Mixed Methods Study, Cynthia Renee Boyle

Graduate Student Theses, Dissertations, & Professional Papers

Ableism, defined as beliefs and practices that prioritize able-bodiedness and lead to disability discrimination, is a prevalent but often overlooked form of oppression rooted in the historical American legacy of other forms of prejudice, discrimination, and is foundationally rooted in higher education through eugenics. Despite the counseling profession's mandate for multicultural competence, disability issues and ableism are often excluded from mainstream curriculum, contributing to a knowledge gap among counselor educators. This convergent mixed methods study explored and analyzed counselor educators’ understanding of ableism using a cross-sectional questionnaire administered to 48 participants. Quantitative results indicated a positive correlation between more formal …

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines the changing affect of fear in the environment and how it is influencing writing in the Anthropocene. Chapter one lays the groundwork for the present moment of ecocriticism, examining how the relationship with the environment has changed throughout the history of ecocritical writing. The second chapter examines how fear has been an intrinsic element of environmental storytelling, starting with the romantic ideas of the sublime. With the recognition of the impact that humanity has had on Earth over the past several centuries, and the accelerating acceptance of the idea of the Anthropocene since the turn of the …

Suba-Cubun Chibquyioa Muysc-Cubun Chibchichuasuca: Sound Reconstruction Of Muysca In The Context Of Language Reclamation., Brenn Timoteo Romero Moreno

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines the phonological system of Muysca, a Chibchan language once spoken in central Colombia and currently dormant. Its goal includes supporting the revitalization efforts of the Muysca people of Suba. Drawing from a documentation produced in the 17th century by Catholic missionaries and engaging with comparative and historical linguistic methods, I argue for the existence of specific phonemes in Muysca —/ə/, /kʷ/, /tʲ/, and /ʔ/— which are not consistently identified in recent literature. My analysis is situated within the framework of Mediated Language Change (Hinson 2019), which acknowledges the need for Indigenous communities to actively shape the development …

An Exploration Of Resilience In Native American Older Adults, Georgie Victoria Ferguson

Graduate Student Theses, Dissertations, & Professional Papers

Native American older adults remain underrepresented in psychological research. The unique cohort of participants in this study (born 1924 - 1957) possesses experience and knowledge that can greatly enhance the knowledge base and contribute to the overall understanding of culturally embedded resilience. Participants contributed to the identification of Spirituality and Humor as positive, culturally embedded coping factors through a set of qualitative interviews, and the present study further investigates those specifically identified coping processes using quantitative measures. This research explores how these constructs (measured by the Spiritual Well-Being and Multidimensional Sense of Humor Scales) might counteract (main effect) or buffer …

There's Still Time To, Lily Kip

Graduate Student Theses, Dissertations, & Professional Papers

There's Still Time To is a body of work composed of 51 photo-derived oil paintings. Each piece illustrates a relational situation which resists straightforward interpretation and generates infinite narrative possibilities. My source images come from my adolescent engagements with smartphone photography and social media, but the painted results are not focused on "photography" as a subject. Instead, I paint the photo to re-tread old memories and old relationships. The ambiguity of each figurative situation reflects the lived experience of relating to others and also serves as an invitation to the viewer who must base any assumptions about the painting on …

Mitochondrial Dna Diversity In West Mexico, Emma Zoiss

Graduate Student Theses, Dissertations, & Professional Papers

The long-standing movement of people, exchange of goods, and transmission of cultural traits are imprinted not only in the archaeological record but also within the genomes of individuals, making ancient DNA a powerful tool for uncovering past interactions and population dynamics. Despite attempts at systematic research, we are still missing critical information about pre-Columbian Mesoamerican populations in the Aztatlán region. This research will focus on those individuals recovered from archaeological sites located both in the highlands of the Lake Chapala Basin, as well as the coast of the Aztatlán core region. The integration of genetics into our understanding of the …

Pathways And Places: Mobility And Lithic Use At 48ye238 In The Late Archaic And Late Prehistoric Yellowstone, Jacob Q. Wilmoth

Graduate Student Theses, Dissertations, & Professional Papers

Through the lens of Central Place Foraging Theory, an analysis of lithic remains from 48YE238, a medium to high-density archaeological site in the Hayden Valley of Yellowstone National Park, has provided insight into both material value and decision-making among Late Archaic and Late Prehistoric hunter-gatherers of the Hayden Valley. First, an examination of lithic materials and the stages of bifacial reduction, in relation to sourced lithic materials, offers insight into changing ideas of material value between these two periods. This is especially evident when considering the cultural and societal changes that influenced regional residence during the Late Prehistoric period, compared …

Visual Semiotics In Parks: Assessing Pictorial Symbol Effectiveness In Outdoor Recreation Settings, Miranda Jane Foster

Graduate Student Theses, Dissertations, & Professional Papers

As interest in outdoor recreation grows, so does the need for effective communication in parks and protected areas. With a larger, more diverse visiting population, managers face new challenges, including intensified recreational use, staffing demands, and barriers to communication presented by cultural and linguistic diversity (Manning et al., 2017; Perry et al., 2021). Effective, indirect communication tools, such as pictorial symbol signage, are essential for addressing these challenges. Pictorial symbol signs are widely used in recreational signage and serve as vital indirect management strategies for communicating to diverse visitors as a universal visual language (Davies et al., 1998). However, research …
