Native American Speech-Language Pathologists: Voices And Perspectives, Lexi Woods
Native American Speech-Language Pathologists: Voices And Perspectives, Lexi Woods
Graduate Theses and Dissertations
Abstract: This narrative inquiry centers the lived experiences and professional voices of Native American speech-language pathologists (SLPs) working with students with disabilities on tribal lands, a population that remains unheard within special education and speech-language pathology research. Grounded in Indigenous epistemologies that honor relationality, storytelling, and community accountability, this study explores how Native American SLPs navigate systemic inequities, cultural and linguistic mismatches, and institutional constraints while providing services in public, tribally controlled, and Bureau of Indian Education schools. Through in-depth narratives, the research illuminates how participants resist deficit-based approaches by reframing silence, communication styles, family engagement, and disability through culturally …
Ontogenetic Variation In Palatal Morphology In Tufted And Untufted Capuchins, Valerie Contreras
Ontogenetic Variation In Palatal Morphology In Tufted And Untufted Capuchins, Valerie Contreras
Graduate Theses and Dissertations
ABSTRACT Craniofacial variation and its relation to diet have been widely examined, but with less attention exclusively to the palate. Previous studies have shown that groups consuming a more resistant diet exhibit morphological differences in the craniofacial skeleton, including a longer and wider palate when compared to groups consuming a less resistant diet; similar patterns have been observed among captive vs. wild populations. Here, I present a 3D morphometric analysis of palatal ontogeny in tufted (Sapajus spp.) and untufted (Cebus spp.) capuchins and compare captive vs. free-ranging semi-provisioned Sapajus. Tufted capuchins are known to consume more mechanically resistant foods compared …
In The Shadow Of The Steeple: A Theory Of Religious Hypocrisy, Justin Arthur Rice
In The Shadow Of The Steeple: A Theory Of Religious Hypocrisy, Justin Arthur Rice
Graduate Theses and Dissertations
In this dissertation, I explore how Christian doctrine and practice respond to the pressures placed upon them by the troubling reality of religious hypocrisy (RH). Assuming a teleological notion of social institutions, I argue that RH is best understood in relation to the Church as an institution, and that RH occurs when religious agents undermine or subvert their appointed role within the Church. RH consists in the conscious or unconscious charade of spiritual or moral virtue undertaken in one’s capacity as a member of a religious institution, grounded in a fundamental disparity between one’s thoughts, words, desires, motivations, or deeds, …
Physics-Informed Machine Learning For Predictive Digital Twins In Greenhouses, Hoang Kim Tran
Physics-Informed Machine Learning For Predictive Digital Twins In Greenhouses, Hoang Kim Tran
Graduate Theses and Dissertations
Greenhouses are widely used to create controlled environments for crop production, where indoor climate variables such as air temperature, relative humidity, CO2 concentration, radiation, and soil or substrate conditions directly affect plant growth, yield, energy consumption, and resource use. However, greenhouse climates are highly dynamic because they are influenced by complex interactions among outdoor weather, greenhouse structure, crop transpiration, heating systems, ventilation, screens, fans, irrigation, and other actuators. Building digital twins for greenhouses provides a powerful way to represent, monitor, and predict these climate dynamics. A predictive digital twin can simulate future indoor climate states based on current greenhouse conditions, …
Localizing And Repairing Backdoor-Sensitive Layers In Pre-Trained Language Models For Secure Fine-Tuning, Sunanda Das
Localizing And Repairing Backdoor-Sensitive Layers In Pre-Trained Language Models For Secure Fine-Tuning, Sunanda Das
Graduate Theses and Dissertations
Task-agnostic backdoor attacks can contaminate pre-trained language models (PLMs) in a way that survives downstream adaptation, even under full fine-tuning, making it difficult for practitioners to trust third-party checkpoints. Existing defenses often rely on privileged assumptions (e.g., access to poisoned data or trigger/target knowledge), thereby limiting their applicability in realistic settings. We present DiSec (Disentanglement of potentially adversarial weights for Secure fine-tuning), a robust and label-efficient purification framework that uses only clean auxiliary text and does not rely on downstream supervision or attack signatures. DiSec elicits model-internal signals from this clean data to separate suspicious parameter components that are inconsistent …
From Learner To Leader: Exploring Principals' Perspectives On Professional Learning, Development, And Mentoring, Eric William Kausch
From Learner To Leader: Exploring Principals' Perspectives On Professional Learning, Development, And Mentoring, Eric William Kausch
Graduate Theses and Dissertations
This purpose of this qualitative study was to examine veteran secondary school principals’ engagement in professional learning, development, and mentoring for the improvement of their leadership skills. While previous literature provides insight into administrative preparation programs, mentoring of novice leaders, and succession planning for those advancing their careers, there are fewer studies that discuss enhancing experienced principals’ leadership development. The study was guided by three research questions: (1) How do principals describe their experiences participating in professional learning and development? (2) What types of leadership experiences do principals engage in to improve their leadership skills? and (3) How does engaging …
Drawing Conclusions: Autonomy And Mental Maps In Denmark And The Faroe Islands, Erik Steven Breidinger
Drawing Conclusions: Autonomy And Mental Maps In Denmark And The Faroe Islands, Erik Steven Breidinger
Graduate Theses and Dissertations
This dissertation develops and tests a comparative heuristic device called optimal autonomy to explain when and how autonomous territories, or simply autonomies, become durable components of the global system of sovereign states. Drawing on a mixed‑methods case study of Denmark and the Faroe Islands, the study operationalizes optimal autonomy as a heuristic device using three interacting metrics: territorial delineation, national distinction, and state dependence. Using semi‑structured interviews with public officials and a mental‑mapping experiment with university students, this research shows that optimal autonomies are not made from single institutional designs but rather a dynamic equilibrium between maximal territorial delineation, medial …
A Dual Analysis Of Generic Stereotypes, Shaoneng Xu
A Dual Analysis Of Generic Stereotypes, Shaoneng Xu
Graduate Theses and Dissertations
In my thesis, I provide a dual-analysis on generic stereotypes, including a semantic analysis that focuses on the truth conditions of generic sentences as well as a pragmatic analysis that focuses on the normative force of generic stereotypes. The thesis contains two parts: In the first chapter, I make a semantic analysis of generic stereotypes based on Lemeire’s (2020) paper. I unpack the general concept of generic sentences and their truth-conditions. I also discuss Lemeire’s rebuttal strategies to offensive generic stereotypes, and add to it by indicating that generics can also carry normative forces. In the second chapter, I make …
Advancing Social Media Analytics And Personalized Generation Via Transfer Learning, Discourse-Aware Modeling, And Collaborative Modeling, Gibson Nkhata
Graduate Theses and Dissertations
Social media platforms have become central to information exchange, shaping public opinion across social, political, and economic domains. However, the massive volume of user-generated content, combined with its informal, nuanced, and often noisy nature, presents significant challenges for automated analysis and generation. Tasks such as stance detection, rumor verification, and personalized content generation are further complicated by sarcasm, evolving discourse structures, and diverse user preferences. Addressing these challenges requires models that can effectively leverage linguistic nuance, conversational dynamics, and collaborative user signals. Transfer learning has emerged as a powerful paradigm for improving performance in low-resource and complex language understanding tasks. …
The Narrative Dynamics Of Special Books By Special Kids Youtube Videos And Comments: A Study Of Disability Rhetoric And Public Narrative Engagement, Jessica Louise Allee
The Narrative Dynamics Of Special Books By Special Kids Youtube Videos And Comments: A Study Of Disability Rhetoric And Public Narrative Engagement, Jessica Louise Allee
Graduate Theses and Dissertations
Digital media has expanded disability advocacy and community building by enabling accessible, visual storytelling and connection. Special Books by Special Kids (SBSK), a YouTube channel using interview-based disability storytelling, foregrounds people’s experiences with disabilities in the videos, while inviting viewers to interpret, identify with, and respond in the comments. As a participatory storytelling space, SBSK offers a site for examining how disability meanings are constructed, negotiated, and transformed through narratives, multimodal practices, and audience uptake, while revealing how dominant disability rhetoric or ableist discourse that positions people with disabilities as burdens, inherently deficient, or socially devalued, can be reproduced, complicated, …
Navigating Mixedness As A Multiracial Teacher, Casey S. Kraichoke
Navigating Mixedness As A Multiracial Teacher, Casey S. Kraichoke
Graduate Theses and Dissertations
This qualitative hermeneutic phenomenological study utilized Critical Multiracial Theory (MultiCrit) to construct a counternarrative that amplifies the voices of Multiracial teachers, focusing on the development of personal and teacher identity. Specifically, the study critically examines the trajectory of Multiethnic-Racial (ME-R) identity transformation following experiences teaching English as a Foreign Language (EFL) in participants’ heritage Asian countries. Data were collected through one-time semi-structured virtual interviews with fifteen purposefully selected Asian-White Multiracial EFL teachers who had completed a one-year Fulbright English Teaching Assistantship (ETA) within the past decade. Each participant also provided a written artifact to support the analysis. Participants reflected on …
Genre Prediction Using Rnns And Llm-Enhanced Video Game Review Data, Gabriel Young
Genre Prediction Using Rnns And Llm-Enhanced Video Game Review Data, Gabriel Young
Graduate Theses and Dissertations
LLMs (Large Language Models) are powerful tools for engaging with textual data, carrying many advantages over classical NLP (Natural Language Processing) and ML (Machine Learning) approaches. However, a classical ML model can still be faster, more efficient to run, and accessible than an LLM. We seek to gain the benefits of LLM text comprehension and preserve them in a classical ML model, a hybrid approach. The LLM operates on text to surface relevant information and associations in our problem space, then the ML model trains on the LLM output. The model may learn from the LLM and provide a more …
Learning At Lunch: A Qualitative Examination Of Lunchtime Discourse In Preschool Classrooms, Savanna Lynn Gragg
Learning At Lunch: A Qualitative Examination Of Lunchtime Discourse In Preschool Classrooms, Savanna Lynn Gragg
Graduate Theses and Dissertations
This mixed-methods study examined how preschool teachers understand and use mealtime as an opportunity for children’s learning and connection. The project explored teachers’ beliefs, observed mealtime practices, and used collaborative video reflection to examine how teachers’ perspectives and behaviors evolved over time. Over five weeks, mealtimes were recorded, transcribed, and analyzed alongside reflection sessions with the teacher. Using the Arkansas Child Development Early Learning Standards (CDELS) as a developmental lens, each mealtime interaction was coded for learning opportunities across domains such as language, literacy, social-emotional growth, and self-help skills. Findings indicated that as the teacher engaged in video-supported reflection, mealtime …
"Shhh": A Reflection On Matrescence, Anna Guillory
"Shhh": A Reflection On Matrescence, Anna Guillory
Graduate Theses and Dissertations
“Shhh” is a collection of drawings that reflect on the many ways the first year of motherhood shifts identity, perspective, and relationships. Focusing on my personal experience of becoming a caregiver, each work acts as an exploration and artifact of the shared labor between parenting and redeveloping an art practice, articulating both the tension and the enmeshing of these two realities. The work poses questions around value and production and consequently presents considerations of the passage into matrescence itself. Through a combination of rendered images, gestures and marks from observed moments in domestic space, postpartum life, and my own inner, …
"Because You Speak Two Languages": Latino Immigrant Families Negotiating Language Ideology, Liminality, And Education In Arkansas, Cindy Rauth
Graduate Theses and Dissertations
This dissertation presents a critical ethnographic study of lower socio-economic status, multilingual Latino immigrant families in one region of Arkansas, which has undergone rapid demographic changes in the last four decades. As the Latino population has grown, schools have struggled to accommodate the needs of their diverse students and families, which has contributed to below-grade-level literacy skills and significant student disengagement. This study examines students’ schooling experiences from the perspective of the family. Through an interdisciplinary approach, this study explores three interconnected themes: family experiences of schooling, language ideology, and liminality. A comprehensive examination of family educational experiences includes the …
‘Enemy Communist Cocksuckers’: Conceptualizing Patriotic Masculinity In Threats To Election Officials, Alma Harrison
‘Enemy Communist Cocksuckers’: Conceptualizing Patriotic Masculinity In Threats To Election Officials, Alma Harrison
Graduate Theses and Dissertations
Research on political violence demonstrates how certain aspects of masculinity are linked to asserting ideological authority and reinforcing exclusionary social identities through physical aggression, such as assaults, homicides, and gender-based violence. However, little research analyzes the use of violent threats as masculinity performances to achieve these same ends. To address this gap, this study analyzes messages from qualitative interviews with 26 election officials who experienced violent threats, examining performances of a distinct form of masculinity – patriotic masculinity – which fuses hegemonic masculine norms with patriotic values. Findings reveal ways in which actors construct and perform patriotic masculinity to frame …

Culturally responsive and relevant education (CRRE) teaching practice are crucial to implement at the tertiary level to support post-graduate preparation for students from marginalized communities. This case study explores the impact, or lack thereof, of these teaching principles in a higher education program specifically created to support diverse populations of students in preparing for graduate level studies and professions in academia. Data were collected via one-on-one interviews with students and staff in the program. Data were then analyzed to explore the extent to which culturally CRRE principles were integrated into TP and how that integration impacted student preparation for academia. …
Developing A Questionnaire For The Interoceptive Awareness Of Stuttering, Leslie Williams
Developing A Questionnaire For The Interoceptive Awareness Of Stuttering, Leslie Williams
Graduate Theses and Dissertations
Stuttering is commonly measured through its overt characteristics (blocks, prolongations, and repetitions). This equates to stuttering “severity,” or the frequency of these behaviors. This method, however, does not reflect the lived experience of adults who stutter. This “measurement problem” has been the subject of numerous studies. In this graduate thesis, the measurement problem is addressed by using qualitative data previously gathered by Malcolm (2024) from adults who stutter about the internal experience of stuttering to create survey. Quotes from adults who stutter were gathered, categorized, edited for clarity, and formatted into a survey, The Multidimensional Interoceptive Awareness of Stuttering Scale …
The Ideological Becoming Of Elementary Teacher Candidates And Their Beliefs About Literacy Instruction, Megan Chaffin
The Ideological Becoming Of Elementary Teacher Candidates And Their Beliefs About Literacy Instruction, Megan Chaffin
Graduate Theses and Dissertations
This study explored the ideological becoming (Bakhtin, 1981) of elementary teacher candidates (TCs), specifically in relation to their beliefs about literacy, as they completed their literacy coursework and corresponding clinical experiences in their educator preparation program (EPP). Through a qualitative, multiple-case study design, I followed two groups of TCs through the last two years of their undergraduate degree. Each group of TCs completed a series of four literacy methods courses with associated clinical experiences, and one group also finished their student teaching internships. The cases in this study are situated in the context of an era of educational policies that …
Writing Through The Plague: Memory, Trauma, And Survival In Arabic And English Narrative, Zainab Abbood Jawhar Aldaoseri
Writing Through The Plague: Memory, Trauma, And Survival In Arabic And English Narrative, Zainab Abbood Jawhar Aldaoseri
Graduate Theses and Dissertations
This thesis examines how Arabic and English literary and intellectual traditions responded to the Black Death as a shared yet differently articulated experience of collective trauma. Drawing on trauma theory, particularly the work of Cathy Caruth and Dominick LaCapra, it analyzes how plague narratives function as cultural mechanisms for processing mass suffering. Through a comparative study of Arabic historiographical, theological, medical, and poetic texts alongside English allegorical, mystical, autobiographical, and satirical writings, this project argues that both traditions developed distinct narrative strategies to render the trauma of plague intelligible. Arabic plague literature, represented by figures such as Ibn Khaldūn, Ibn …

Understanding How Ai Chatbots Act As Gatekeepers When Recommending Destinations, Ayden Alexandra Carmack
Graduate Theses and Dissertations
As artificial intelligence chatbots become a primary tool for travel discovery, questions arise about whose destinations get recommended and how. This study examines how ChatGPT (OpenAI), Claude (Anthropic), and Google Gemini function as algorithmic gatekeepers in travel recommendations, drawing on gatekeeping theory, framing theory, and growing scholarship on AI bias in tourism. Using a content analysis of 135 AI-generated responses to 15 standardized travel prompts (45 per platform, each run three times) this study coded destination selection patterns, dominant narrative frames, and informational omissions across platforms. Results show that 88.9% of recommended destinations were classified as high-income nations, with Japan, …

Emotion Analysis And Neural Language Models For Classification, Andrew Mackey
Graduate Theses and Dissertations
Emotion analysis is a branch of artificial intelligence and natural language processing focused on recognizing emotions hidden throughout various forms of digital data, including text, images, and multi-modal representations. In this dissertation, we present four published and planned works that investigate different methodologies for natural language analysis tasks using deep learning techniques. The first published work we present considers the task of identifying fake news using various text and emotion representations. We demonstrate that emotion representations combined with word embedding techniques can improve the accuracy of fake news classification. Our second published work further investigates the fake news classification task …

The aim of this study was to examine local newspaper coverage of the Marshallese community in Northwest Arkansas from 1998 to 2017 and analyze discourses that could be attributed to linguistic bias, stereotypes, and Pacific transnationalism. This analysis examines how marginalized immigrants are portrayed in local news coverage using a critical discourse analysis (CDA). The study analyzes the labels and metaphors used in the coverage of Marshallese immigration, adapts the Stereotype Content Model for a discourse analysis, and compares the experiences of Marshallese in the area with larger scholarly work on Pacific transnationalism. The researcher analyzed 11 published pieces from …
Reading Between Lines: Mapping El Orinoco Ilustrado, Guillermo Pupo Pernet
Reading Between Lines: Mapping El Orinoco Ilustrado, Guillermo Pupo Pernet
Graduate Theses and Dissertations
This dissertation examines El Orinoco Ilustrado (EOI) by Joseph Gumilla as a layered textual and cartographic artifact central to the production of colonial knowledge in the Orinoco River basin. Moving beyond surface narratives of evangelization and exploration, it interrogates the sombras and silencios implanted in the Jesuit chronicle. Through an intradisciplinary approach combining literary analysis, archival research, and visual studies, the study reveals how EOI helped construct imperial visions of space, race, and resource extraction in eighteenth-century Spanish America. The dissertation is structured around six chapters. Chapter One outlines a theoretical framework. Chapter Two provides a longue durée historical context, …
Using Artificial Intelligence (Ai) To Improve The Identification Of Gifted Students, Hamid Ahmad Almalki
Using Artificial Intelligence (Ai) To Improve The Identification Of Gifted Students, Hamid Ahmad Almalki
Graduate Theses and Dissertations
The present study examined teachers' perceptions of using artificial intelligence (AI) to identify gifted students. The issue is clearly relevant today; several schools continue to grapple with unfair practices and irregular assessment processes, most notably for culturally and linguistically different students. Conventional keys and expert opinion remain essential, but their limitations have been acknowledged. Newer research suggests that AI could actually improve the system by making it more efficient and able to pool data that originally surfaced biases. At the same time, issues of transparency, data privacy, and the ethics of decisions driven by AI remain unresolved. To gain an …

Predicting Stock Price Movement With Llm-Enhanced Tweet Emotion Analysis, An Vuong
Predicting Stock Price Movement With Llm-Enhanced Tweet Emotion Analysis, An Vuong
Graduate Theses and Dissertations
Accurately predicting short-term stock price movement remains a challenging task due to the market’s inherent volatility and sensitivity to investor sentiment. In this thesis, we present a published paper that discusses a deep learning framework integrating emo- tion features extracted from tweet data with historical stock price information to forecast significant price changes on the following day. We utilize Meta’s LLaMA 3.1-8B-Instruct model to preprocess tweet data, thereby enhancing the quality of emotion features derived from three emotion analysis approaches: a transformer-based DistilRoBERTa classifier from the Hugging Face library and two lexicon-based methods using National Research Council Canada (NRC) resources. …
Contextual Embedding Using Machine Learning For Cybersecurity: Access Control And Application, Thanh Bui
Contextual Embedding Using Machine Learning For Cybersecurity: Access Control And Application, Thanh Bui
Graduate Theses and Dissertations
Access control is a well-established challenge in cybersecurity, with significant research focused on enhancing system autonomy and accuracy across various scenarios. Access control rules can be designed based on users’ roles, attributes, or relationships requesting access to specific resources. However, despite their benefits, these models still require human oversight. As systems expand and grow, it becomes increasingly complex for administrators to maintain precise access control rules, often necessitating extensive system updates or even a complete overhaul. This dissertation introduces a novel approach that leverages contextual embedding for user information to enable the system to autonomously authorize user requests for resources. …
