School-Based Mental Health Services For Students With Disabilities: Exploring Benefits, Barriers, And The Role Of A Multi-Tiered System Of Supports, Veronica R. S. Meiners Perez

Electronic Theses, Projects, and Dissertations

Schools play a significant role in the academic, behavioral, and social-emotional development of children. Students with disabilities have legal rights to all necessary support for their educational success, including mental health supports. School-based mental health and its implementation are a work in progress, facing many barriers, but the benefits speak for themselves. Research suggests that the use of a multi-tiered system of supports ensures equal and equitable interventions for all students, especially students with disabilities. This literature review analyzes 16 studies regarding school-based mental health, special education, students with disabilities, and the MTSS framework. Support students' mental health, regardless of …

Robustness Of Network Inference Algorithms Under Network Class Misspecification, Roberto Ceja

Electronic Theses, Projects, and Dissertations

Inferring phylogenies in the presence of hybridization remains a difficult problem. As a result, many current methods for reconstructing phylogenetic networks are restricted to a simple class of networks known as level-1. This restriction arises from theoretical considerations rather than empirical evidence, with real data possibly arising from complex networks. In this work, we evaluate the robustness of two level-1 network inference methods, SNaQ and NANUQ+, through a simulation study, when the input data originates from a more complex network. Specifically, we investigate whether these methods can accurately recover important features of the true species network, such as the circular …

Parental Involvement In Bilingual Language Learning In Early School-Aged Children, Jennifer Y. Arroyo Morales

Electronic Theses, Projects, and Dissertations

This project examines the critical role of parental involvement in supporting bilingual language learning (BLL) among early school-aged children in kindergarten through third grade. Bilingualism offers extensive cognitive, social, cultural, and economic benefits, yet many families face barriers that limit their ability to foster bilingual development at home. Grounded in Vygotsky’s Social Interactionist Theory and Kuhl’s research on sensitive periods of language acquisition, this project developed the Parent Handbook for Supporting Bilingual Language Learning in Early School-Aged Children. The handbook provides parents with accessible, research-based strategies that transform everyday routines into opportunities for bilingual growth. Designed to address barriers such …

Un-Imagining The Anglo Southwest And The Impossibility Of Trans-Scription, Lynnette M. Maphies

Art & Art History ETDs

This thesis is an interrogation of the Anglo Southwest as a problematic and persistent regional and national construct. I propose that the Anglo Southwest emerged at a pivotal moment in the late nineteenth century during which Americanist approaches to geography, anthropology, and the arts, were being shaped to define the region and determine the production and distribution of knowledge. This resulted in an Anglo view of the Southwest as uninhabited, silent, and imaginary, which omitted the actuality of silencing Native voices, cultural appropriation, and the taking of resources and land. Army surgeon and amateur ethnographer Washington Matthews (1843–1905) serves as …

Culturally Responsive Functional Communication Training For Asian Families: A Single-Subject Design Study, Guofeng Shen

Dissertations

Children with disabilities, such as autism spectrum disorder (ASD) and intellectual disability (ID), frequently experience challenges related to social communication and are at increased risk of exhibiting challenging behaviors (CBs), particularly when they lack effective means to express their needs and desires. Functional communication training (FCT) is an evidence-based intervention shown to reduce CBs by teaching functional communication skills. However, limited research has explored the use of culturally responsive adaptations of FCT (CRFCT), particularly in the context of training parents from culturally, linguistically, and economically diverse backgrounds. This study addressed this gap by examining the effects of culturally responsive FCT …

Exploring The Use Of Culturally And Linguistically Responsive Practices Within The Multi-Tiered System Of Support (Mtss) Framework When Supporting Students With Disabilities At A Dual Language Immersion School, Sylvia Simmons

Dissertations

The integration of culturally and linguistically responsive practices (CLRP) within the Multi-Tiered System of Support (MTSS) framework has been recognized as a promising method for improving learning opportunities for diverse students. However, little to no research has been conducted on the intersection of CLRP within the MTSS framework to support students with disabilities in dual language immersion schools (DLI). This lack of research has posed challenges for educators seeking effective strategies to support diverse learners with disabilities in such settings. Therefore, the purposes of this qualitative case study were to (a) explore how a dual language immersion school utilizes the …

Culturally Relevant Pedagogy In Teaching And Learning In High School Social Studies Curricula In Georgia: A Case Study, Sharon Ann Mcmeans-Lukiri

Dissertations

Despite increasing diversity within Georgia’s high school student population, it remains unclear to what extent social studies teachers incorporate Culturally Relevant Pedagogy (CRP) in the planning and implementation of their instruction. Recent research indicates that many educators continue to struggle with developing effective instructional practices that meet the learning needs of students from vulnerable communities (Liasidou & Symeou, 2018). Students from these communities often experience lower academic achievement (Ladson-Billings, 2009), and when the curriculum fails to reflect or respond to their cultural backgrounds, they are more likely to disengage from school (Ladson-Billings, 2009). This gap between students’ cultural needs and …

Civics Teachers’ Perceptions Of Disciplinary Literacy Strategies That Use Primary Sources: A Case Study, Whitney Williams

Dissertations

This study has been designed as a case study to examine teachers’ perceptions of document-based strategies when combined with primary sources as pedagogical tools. The participants were ninth grade civics teachers. Semi-structured interviews, focused observations, and artifact collection were the sources of collected data. As the researcher, my constructivism guided this study through the lens of Albert Bandura’s social cognitive theory (SCT). Therefore, the participants’ perception will be interpreted through SCT concepts such as personal influences, behavioral influences, and environmental influences. Findings show a handful of disciplinary literacy strategies that occurred most often across all participants. Teachers valued an emphasis …

Acceptability Of Corticosteroid Use In The Treatment Of Infant Bronchiolitis: Utilizing The Theoretical Framework Of Acceptability To Design Research Instruments, Caroline R. Smetanka

Capstone Experience: Master of Public Health

Bronchiolitis is the leading cause of hospitalization among infants under six months, yet treatment remains largely supportive due to clinical guidelines that discourage pharmacologic intervention. Recent research suggests that bronchiolitis is not a uniform condition, and a subgroup of infants (those classified within “Profile A”) may benefit from targeted corticosteroid therapy. However, these treatments remain outside current clinical guidelines, and their successful adoption depends on stakeholder acceptability. This Capstone project developed and refined four data collection instruments- two questionnaires and two interview guides- designed to assess how healthcare providers and caregivers perceive the acceptability of corticosteroid treatment for Profile A …

Open Access Theses & Dissertations

This qualitative study investigates how dual language educators in elementary schools along the U.S.–Mexico border create language-rich learning environments with the Spanish resources available to them. Motivated by longstanding shortages of adequate Spanish instructional materials in bilingual classrooms, this study examines the extent to which this challenge persists in contemporary educational contexts. Grounded in translanguaging theory (de la Piedra, Araujo, & Esquinca, 2018; Flores & Chaparro, 2018; Otheguy, García, & Reid, 2015) and the funds of knowledge framework (González, Moll, & Amanti, 2005), the study explored: (1) the materials provided by districts and schools, (2) the challenges teachers face with …

From Morphology To Machine Learning And Genomics: Understanding Phenotypic Variation In Wild Ducks, Sara Gonzalez

Open Access Theses & Dissertations

Understanding the genetic underpinning and distribution of phenotypic variation within and between divergent groups is core towards shedding light into how populations diverge and adapt, as well as how hybridization breaks or builds on these scenarios; and thus, central to evolutionary biology. In wild organisms, however, quantifying and linking phenotypic traits to underlying genetic processes, like mutation, gene expression, epigenetics and allele interactions, remains challenging. This difficulty arises from the complex interplay between morphology, environment, and gene regulation, as well as the logistical barriers of collecting and standardizing large-scale data across individuals and populations. As a result, researchers are increasingly …

Desmadre, Xiomarra Milann Gonzalez

Open Access Theses & Dissertations

My project functions as a collection of poems that each hold stories that tie them into the theme of their assigned subsection and into the greater narrative that each subsection creates, resulting in the takeaway from the overall manuscript. From the first word of the introductory poem, to the final line of the concluding, the poems take you on a journey from a feminine existence that is struggling at the helm of external, oppressive forces leading into a self-reckoning and embracing their own internal power within the systematic chaos and uncertainty that plagues them through the underlying notes of each …

This thesis compares the performance of GPT-5 and Gemini 3 Pro in generating system functional requirements for the Miner Guardian Drone, a prototype UAV designed for minefield remediation. Both models were provided with identical prompts and tasked with producing 15 functional requirements. Two independent raters evaluated the outputs using a nine-dimensional quality rubric aligned with IEEE 29148 and INCOSE guidelines to ensure rigorous assessment. The difference between the models was analyzed using descriptive statistics and …

Book Bans And Border Texans: Testimonios From The Middle, Laura Calvillo Neill

Open Access Theses & Dissertations

This qualitative study explores how Chicana and Mexican American teachers and librarians along the Texas-Mexico border describe their experiences navigating books bans and curriculum restrictions. Through a Chicana feminist epistemological lens, the research centers the testimonios of four educators who reflect on their lived experiences navigating censorship, representation, and professional identity in politically charged educational spaces.

Using a testimonio-based methodology, participants shared personal narratives that illuminated how state politics and local interpretations of "appropriate" texts shape classroom and library decisions. Thematic analysis of these testimonios revealed four interconnected findings: 1. Teacher identity under pressure, 2. Censorship and control in the …

From Feedback To Insight: Using Hierarchical Clustering Analysis To Identify And Analyze Feedback Dimensions In Online Courses, Reagan R. Siggard

All Graduate Theses and Dissertations, Fall 2023 to Present

The demand for online courses continues to increase, as do the critiques of their effectiveness. Studies have found that peer interactions positively impact the online course experience and that peers can offer feedback to each other at the instructor's level with proper guidance. To help understand this feedback, researchers have identified feedback dimensions. Most feedback dimensions have been created through inductive coding, not exploratory data analysis approaches. This study sought to identify those feedback dimensions that perhaps had been missed or were highly associated with those already existing in the literature, hoping to inform research and practice to improve the …

“Are There Any British Soldiers In Tobruk?” National Identity During The Siege Of Tobruk, May To November 1941, Stewart Golightly Weight

All Graduate Theses and Dissertations, Fall 2023 to Present

Throughout this thesis, I examine what it meant to be British during the 1941 Siege of Tobruk. This is important as it reveals previous assumptions about the Second World War’s British Army, including its religious practices and regional distinctions, were more diverse and influential than previously assumed. To do this, I analyze previously overlooked sources concerning religion, morality, and regional identities to demonstrate that Second World War Britishness was not monolithic.

A Critical Policy Analysis Of Dual Language Education Policies On The Equity And Opportunity Of Participation And Access For Multilingual Learners, Justin A. Andersen

All Graduate Theses and Dissertations, Fall 2023 to Present

Dual Language Immersion programs help students become fluent in two languages while achieving academic success. Originally designed to support students who speak languages other than English at home, these programs have grown rapidly across Utah and the U.S. However, they increasingly serve white, English-speaking families seeking enrichment opportunities, while multilingual students who could benefit most remain underrepresented.

This study examined recruitment and admissions policies in two Utah school districts’ dual language programs. By comparing policy documents, analyzing enrollment data, and interviewing district staff, school leaders, and parents, the research revealed significant implementation differences despite identical statewide program requirements.

One district …

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

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. …

Multi-Hop Hybrid Graph Neural Network, James Arthur

Open Access Theses & Dissertations

Graph-structured data appear across diverse domains, such as social networks, citation graphs, biological systems, and knowledge bases. Graph Neural Networks (GNNs) have emerged as a powerful framework for learning on such data, yet existing architectures face significant challenges. Graph Convolutional Networks (GCNs) suffer from over-smoothing as depth increases, Graph Attention Networks (GATs) introduce computational and statistical instabilities, and naïve multi-hop propagation inflates memory and computation while failing to adapt to topology. These limitations motivate the development of a new framework that is both expressive and scalable. This dissertation proposes the Multi-Hop Hybrid Graph Neural Network (MHHGNN), a novel architecture that …

Borderlines Of Becoming: Transfronterizx College Students Navigating Surveillance, Hybridity And Belonging Along The Us-México Border, Aylin Garcia

Open Access Theses & Dissertations

This narrative literature review examines the educational experiences of transfronterizx college students along the U.S.– México border, a population largely absent from higher education scholarship. Drawing on Borderlands Theory, Anzaldúa’s frameworks, and critical perspectives on neoliberalism and militarization, this thesis highlights the border as a site of both constraint and possibility. Structural violence, surveillance, and militarization intersect with linguistic, racial, and class hierarchies to shape students’ mobility, identities, and sense of belonging. At the same time, students mobilize hybrid identities, cultural wealth, and transborder networks to assert agency, cultivate belonging, and resist deficit narratives. It also identifies persistent gaps, particularly …

For this study, STEM degrees refer to those recognized by the …

Phishibl: A Systematic Evaluation Of Instance-Based Learning Model For Predicting Phishing Susceptibility, Shova Kuikel

Open Access Theses & Dissertations

Despite enormous efforts to develop defenses against phishing attacks, humans still struggle to detect phishing emails given the constantly evolving attacker strategies. This thesis aims to test the predictive capabilities of a cognitive model that represents the individual susceptibility to phishing emails. While training programs aim to raise awareness, most remain outdated and ineffective against evolving attack strategies. Recent advances in Machine Learning, Artificial Intelligence, and Large Language Models (LLMs) offer new defenses, yet understanding human decision processes remains crucial, as effective systems must emulate how people evaluate unfamiliar emails based on prior experience. This research introduces a cognitive model …

Our Trajectories As We Leave The Teaching Profession: Pláticas With Former Bilingual Teachers On The U.S.-Mexico Border In Texas- An Explanatory Sequential Mixed-Methods Study, Carla Medina Jaquez

Open Access Theses & Dissertations

Teacher attrition has had a negative impact on the educational system for many years. New and experienced teachers have been leaving the classroom. Although the reasons appear repetitive, we know relatively little about what teachers must go through when deciding to leave the profession and what happens to them afterward. A teacher shortage is occurring along the U.S.-Mexico border, as in many other cities across the United States. Despite undergoing a lengthy certification process, teachers continue to leave the classroom. This research employed an explanatory sequential mixed-methods design to explore how new and experienced teachers navigate their transition out of …

“War Is God” And “Unguessed Kinships”: Blood Meridian And Cormac Mccarthy’S “Border Tetralogy”, Seth Reeves

Electronic Theses and Dissertations

This thesis applies the metaphysics of philosopher Gilles Deleuze to Cormac McCarthy’s novel Blood Meridian, arguing that the novel initiates a thread of immanent subjectivity that unfolds throughout the Border Trilogy that follows it. Against a hierarchical metaphysics of transcendence, specifically an inverted Platonic Idealism, Blood Meridian dramatizes an immanent world of “optical democracy,” a prose style that levels the human and nonhuman and eludes subject and object categories. The kid’s autonomy from Judge Holden’s violent domination marks the truncated beginning of a Deleuzian subjectivity of becoming-other and immanent kinship. This incomplete gesture continues in the Border Trilogy, where …
