Caregiver Experiences During Mealtime In Families Of Children With Feeding Disorders In The Borderland, Chyanne Reveles

Open Access Theses & Dissertations

This study examines the lived experiences of caregivers of children with pediatric feeding disorders (PFDs) in the Paso del Norte Region using interpretative phenomenological analysis (IPA). Pediatric feeding disorders require sustained medical, social, and emotional demand, often placing caregivers in complex decision-making roles. Understanding how cultural beliefs and context shape caregiving practices is essential to improving services provided by speech-language pathologists and other service providers. The qualitative research approach used facilitated the discovery of themes surrounding the lived experience of the caregivers of children with feeding disorders. Semi-structured interviews were conducted via Zoom with caregivers residing in the U.S.-Mexico border …

An Ordinal Categorical Data Analysis Using The Stereotype Model Within A Bayesian Framework With A Logistic-Normal Prior, Nathaniel A. Sakyi

Open Access Theses & Dissertations

Ordinal categorical data are pervasive in applied research, yet their analysis is often compromised by modeling strategies that implicitly assume equidistant category spacing or impose restrictive structural constraints. Metric regression models and latent-variable threshold approaches routinely misrepresent ordinal information, leading to biased inference, distorted uncertainty quantification, and loss of structural insight. This paper develops a Bayesian framework for ordinal regression that explicitly accommodates \textbf{unequal spacing among ordered response categories} while preserving ordinal structure and interpretability.

The proposed approach builds on the stereotype regression model, which embeds ordinal categories into a latent one-dimensional continuum through estimable score parameters. While the stereotype …

Fatal Remedies: How France Undermined Its Own Objectives In Algeria, 1954-1962, Elizabeth Mae Tornabene

Open Access Theses & Dissertations

While much of the best-known literature on the Franco-Algerian War has emphasized insurgency, counterinsurgency, and the grievances of the colonized, this thesis takes a broader, historical and public administration approach by analyzing the relationship between the development and implementation phases of government and military policies and the unintended, sometimes fatal, outcomes that followed. Although it does this from the perspective of policymaking in the country that is trying to maintain control over its distant territory, it has implications for those interested in maximizing resistance to these policymakers.

By conducting a structured, focused comparison of a typical case across three theories …

Understanding Gambling Behavior Among Hispanic College Students: The Role Of Attitudes, Norms, Self-Efficacy, And Acculturation, Joshua Torres

Open Access Theses & Dissertations

Gambling has become increasingly accessible and socially normalized among young adults, particularly through mobile platforms and the expansion of legalized sports betting. Hispanic college students may be at heightened risk for gambling-related harms, given evidence of elevated rates of problem gambling, comorbid mental health concerns, and underrepresentation in empirical research. Cultural factors, such as acculturation, may further influence engagement in gambling behaviors and susceptibility to negative outcomes. Guided by the Theory of Planned Behavior, the present study investigated the relationships between gambling injunctive norms, gambling attitudes, and gambling self-efficacy across three outcomes: gambling frequency, problem gambling severity, and gambling intention. …

Language Control Over Structural Representation In Bilinguals, Anahy Barragan-Diaz

Open Access Theses & Dissertations

In daily life, bilinguals sometimes speak each of their languages in situations where the other language cannot be understood. To avoid saying words in the wrong language in such situations, bilinguals inhibit lexical representations from the non-target language (Green, 1998). But do they inhibit structural representations? This study investigated how inhibitory control operates over structural representations in English-dominant Spanish-English bilinguals via a picture description task. An experimental group was asked to describe dative-eliciting pictures in English (Baseline Phase), followed by dative pictures in Spanish (Manipulation Phase), and once again dative pictures in English (Target Phase), while a control group followed …

Blood, Steel, And Stone, Jennifer Camplair Hassell

Open Access Theses & Dissertations

This thesis, Blood, Stone, and Steel, explores the intergenerational impact of trauma, memory, and history through a unique blend of poetry, photography, and personal family narratives. Drawing on archival materials, family photographs, and the tradition of documentary poetry, the work investigates how the legacy of war and immigration shapes identity across generations. Inspired by Marianne Hirsch's concept of postmemory, the author examines inherited memories and their affective transmission, focusing on the experiences of her great-grandfather - a German immigrant and WWI veteran - and the subsequent effects on her family. The narrative is structured in three parts: BLOOD, reflecting loss …

Effects Of Cannabinoid Agonist Win 55-212-2 On Latent Inhibition, Ashley Peterson

All Graduate Theses and Dissertations, Fall 2023 to Present

The endocannabinoid system (ECS) is a modulatory system that helps regulate brain functions, including learning and memory, influencing processes such as latent inhibition (LI). LI refers to the slower association formed when a familiar event is paired with a new outcome, compared to the association of an unfamiliar event. LI is a process that is often disrupted in individuals with schizophrenia and is known as a cognitive symptom. This study aimed to determine whether the drug WIN-55-212-2 (WIN), which interacts with the ECS, influences the process of LI using a fear-conditioned response procedure. The results found no significant interaction among …

Effects Of Tourist Feeding On The Gut Microbiome And Ecophysiology Of Endangered Northern Bahamian Rock Iguana (Cyclura Cychlura), Erin Lucy Lewis

All Graduate Theses and Dissertations, Fall 2023 to Present

The lifespan and reproduction of an animal depends on maintaining a healthy physiology. The proportion of individuals that survive to an age at which procreation can occur is important to long-term stability of populations and contributes to species survival. Health in an animal is measured in a variety of ways, including through monitoring of the body’s physiological systems, as well as its ability to respond to invading pathogens, and through the different types of bacteria present in the gut. Relationships among those different health metrics have been discovered in recent years and have been found to play important roles in …

Exploring Cognitive Load Theory In The Post-Secondary Engineering Classroom, Gabriel Q. Van Dyke

All Graduate Theses and Dissertations, Fall 2023 to Present

Engineering programs often emphasize subject-matter expertise over pedagogical training, which can leave students struggling with course demands and contribute to retention challenges. This study applied Cognitive Load Theory (CLT) to examine how undergraduate engineering students experience the cognitive demands of their coursework compared to non-engineering classes. Using a sequential explanatory mixed methods design, cognitive load surveys were followed by interviews to address two research questions: (1) What are the differences in intrinsic and extraneous cognitive load levels between engineering courses and non-engineering courses taken concurrently by undergraduate engineering students? (2) How do engineering students perceive the unique challenges or benefits …

Parental Socialization Practices As Protective Factors Of Lgbtq+ Youth Well-Being And Sexual Health, Melissa M. Ferguson

All Graduate Theses and Dissertations, Fall 2023 to Present

LGBTQ+ teens face challenges like discrimination and exclusion from school-based sex education. Support from parents is crucial for helping LGBTQ+ teens feel safe and confident. Most research has only looked at how parents react when their child comes out, and less about how parents support their child in everyday life. This two-study dissertation explored how parents help support and protect their LGBTQ+ teens’ well-being over time.

The first study looked for patterns of protective parenting across interviews with LGBTQ+ teens and their parents from diverse racial and ethnic backgrounds. Teens and parents shared their experiences of open communication, building community, …

Online Act Guide For Sub-Clinical And Clinical Insomnia Among College Students, Guadalupe "Gabe" San Miguel

All Graduate Theses and Dissertations, Fall 2023 to Present

College students are shown to have more sleep difficulties, specifically insomnia. These sleep difficulties compared to the general public due to the college environment (for example increase screen time, sedentary time, or alcohol use). Students with reported sleep difficulties have ties to lower GPA and lower odds of graduation. That is why this dissertation conducted a comparison between an online version of Acceptance and Commitment Therapy (intervention) to a placebo condition among college students with insomnia to help determine if the intervention had better outcomes over time. Each condition (intervention = 39; placebo = 40) completed questionnaires at the start …

An Autohistoria-Teoría Of A Pasifika Neptantlera, Belinda 'Ofakihevahanoa Fotu

All Graduate Theses and Dissertations, Fall 2023 to Present

This study was an autohistoria-teoría, a type of autoethnography, where I focused on my writing process as a Pasifika researcher creating a middle- grade fiction. As the researcher, my questions delved into how I engage in writing for a majority-culture dominated publication house in a Western-world writing genre while maintaining the cultural significance of the ancient Pasifika mythologies I reproduced and recontextualized in the novel. The research site was my writing process, and the data gathered came from the variety of ways I navigated cultural stimuli specific to writing the novel. The outcome engaged with the specific way Pasifika (and …

Effects Of Training And Self-Monitoring On Paraeducators' Use Of Behavior Specific Praise, Camille J. Lopez

All Graduate Theses and Dissertations, Fall 2023 to Present

Paraeducators support students with disabilities in special education classrooms but often receive limited training in effective behavior support strategies. This study examined whether training combined with self-monitoring increased paraeducators’ use of positive, specific praise and reduced the use of reprimands during instruction. Paraeducators were trained to use and track their own praise while working with students. Results showed increased use of positive praise and decreased reprimands following the intervention. These findings suggest that brief, low-cost training and self-monitoring can improve paraeducator instructional practices and support positive classroom environments for students with disabilities.

Assessing Young Children's Computational Thinking: Validation Of Items And Item Design Features, And Diagnostic Approaches, Chungsoo Na

All Graduate Theses and Dissertations, Fall 2023 to Present

The goals of this multiple-paper dissertation are to evaluate the psychometric evidence of the Computational and Spatial Thinking Assessment (CaST), designed and developed by the Coding in Kindergarten (CiK) research team (supported by NSF #1842116). In Chapter 2 (Paper 1), I evaluate the psychometric quality of the CaST assessment at the item level. The CaST has moderate item difficulty and high item discrimination, on average, with high reliability and no gender- or age-related item bias. In Chapter 3 (Paper 2), I identify seven item design features from the CaST assessment and examine their impact on item difficulty. All item design …

A Mixed-Methods Investigation Of Physician Compassion In Consultations For Chronic Primary Pain, Sarah Daehler

All Graduate Theses and Dissertations, Fall 2023 to Present

Chronic primary pain refers to physical pain that has no apparent organic cause, cannot be explained by another condition, and has associated psychological distress or functional impairment. Chronic primary pain is common and can significantly interfere with functioning, including occupational or social functioning. Research has shown that physicians struggle to treat this population, with many physicians reporting feeling unequipped and many patients feeling that their physicians are unhelpful and dismissive. Compassion may play a key role in improving these difficult interactions. The present study analyzed a sample of 99 participants with chronic pain and 100 healthy controls to learn more …

Evaluating The Feasibility, Acceptability, And Preliminary Efficacy Of An Online Acceptance And Commitment Therapy Program To Improve Dietary Quality In Highly Stressed Adults, Francesca M. Knudsen

All Graduate Theses and Dissertations, Fall 2023 to Present

Stress can negatively affect both mental and physical health, which can increase the risk for chronic illness. When people feel stressed, they may also find it harder to make healthy food choices, which can further impact their health. Despite this, there are limited treatments designed to help people improve their dietary quality while managing stress. Acceptance and commitment therapy (ACT) is an evidence-based psychological approach that helps people respond more effectively to difficult thoughts and emotions while behaving in ways that are aligned with their personal values. This study tested whether a brief, online ACT-based program, combined with coaching phone …

All Graduate Theses and Dissertations, Fall 2023 to Present

Mental health problems such as depression, anxiety, and stress are common among Ugandan university students and can make it difficult for them to succeed in school or maintain well-being. However, many students do not have access to professional mental health care. Digital self-help programs can make support more available, especially when they are designed to fit the local culture and context. This project examined how an online program called ACT Guide Lite, which teaches skills from Acceptance and Commitment Therapy (ACT), could be adapted for use with Ugandan college students. Students and other university community members first completed the program …

The Dark Side Of Sport: Exploring Conceptualizations And Operationalizations Of Authority Figure-Athlete Abuse, Katherine Nicole Alexander

All Graduate Theses and Dissertations, Fall 2023 to Present

Although sport can be a fun and positive environment, it can also be a unique and common setting for athlete abuse. Coaches and other authority figures can serve in positive and negative caregiving roles, and many athletes report experiencing at least one form of abuse perpetrated by these important authorities during their sporting careers. We have less research on experiences of abuse in athletes from the United States. The current dissertation was designed to explore ways to more effectively and accurately define and measure athlete abuse perpetrated by authorities and coaches among adults in the United States. Given that there …

Social And Institutional Factors Influencing Restoration Decisions In Sagebrush Plant Communities In The Great Basin, Carmen Calzado-Martínez

All Graduate Theses and Dissertations, Fall 2023 to Present

Sagebrush landscapes of the Great Basin in the western United States have changed dramatically over the past century. Invasive grasses, repeated wildfires, and past land-use practices have made it increasingly difficult for native plant communities to recover once they are damaged. Most restoration efforts occur after disturbances such as wildfire, when ecosystems may already be severely degraded. An alternative approach is proactive restoration, which aims to strengthen ecosystems before major damage occurs. 

This dissertation examines whether proactive restoration strategies could realistically be used in sagebrush rangelands and what factors influence their adoption. The research combines three complementary approaches. First, interviews …

An Analysis Of The War On Terror In Textbooks, Kason Kendall

All Graduate Theses and Dissertations, Fall 2023 to Present

This study analyzes how the War on Terror is presented in history textbooks used in the United States and Brazil. Textbooks play an important role in shaping how students understand major global events, including wars, national security, and international relations. However, these materials do not simply present facts, they also reflect specific perspectives and priorities.

The purpose of this study is to analyze how key topics related to the War on Terror, such as the justification for the Iraq War, domestic security policies, treatment of prisoners, and public dissent are portrayed in textbooks from other countries. By comparing these narratives, …

Equity, Diversity, And Inclusion Infrastructures And Faculty Composition: Associations With Undergraduate Student Outcomes At R1 Universities 2011-2021, Niyonta Nahia Chowdhury

All Graduate Theses and Dissertations, Fall 2023 to Present

This study explores how the structure and composition of research universities relate to student outcomes. Specifically, it asks whether having visible Equity, Diversity, and Inclusion (EDI) infrastructures and diverse faculty representation is associated with who enrolls, who graduates, and how graduation rates differ within racial groups at R1 universities in the United States. Using national data from 2011 to 2021, the project analyzes enrollment and graduation patterns across institutions while accounting for differences in geography, governance, and state political context.

Rather than focusing on individual students, the study looks at institutional patterns. It examines how the racial and gender makeup …

Does Psychosocial Stress Moderate The Association Between Indicators Of Vascular Health And Cognitive Performance: An Examination In Native Hawaiian - Pacific Islander And Non-Nhpi Older Adults, Maddy Mills

All Graduate Theses and Dissertations, Fall 2023 to Present

Late-life cognitive decline and dementia that are unrelated to normal aging are a source of major global health concerns. Vascular risk factors, including high blood pressure, high cholesterol, and diabetes, along with psychosocial stress, are well-established risk factors for cognitive decline. However, no research has explored how these variables interact to influence cognitive performance in older adults. Native Hawaiian-Pacific Islanders (NHPI) face disproportionate rates of vascular risk factors linked to cognitive decline, yet this population has been historically underrepresented in health research. As a result, limited evidence exists regarding how these factors collectively impact cognitive performance in this population. This …

The Role Of Response Time In Math Anxiety, Christine K. Hartmann

All Graduate Theses and Dissertations, Fall 2023 to Present

Math anxiety is characterized by feelings of discomfort or distress that are triggered when an individual is tasked with using numbers. Math anxiety impacts people at all ages, from early elementary school into adulthood (for review see Ramirez et al., 2018). In these studies, we investigated the cognitive impact that math anxiety has on both children and adults by measuring their math anxiety and reaction time on two tasks. The first task was the arithmetic affective priming task (AAPT), which purportedly shows that those with math anxiety tend to complete math tasks more efficiently (faster) when they are primed to …

Advancing Context-Aware Detection Of Socially Harmful Discourse Using Transformer-Based Models, Santosh Chapagain

All Graduate Theses and Dissertations, Fall 2023 to Present

Social media platforms are a central part of modern communication, shaping how people share ideas, build communities, and discuss social issues. While these spaces can support connection and self expression, they also enable the spread of harmful language such as hate speech. At the same time, social media is an important place where members of marginalized communities, including sexual and gender minorities, express stress, discrimination, and emotional challenges in ways that are often indirect and context dependent.

This research examines whether modern artificial intelligence systems can better identify harmful language and expressions of minority stress in online posts. The study …

Factors Affecting Mathematics Teachers’ Instructional Decision-Making: An Ecological Systems Theory Multiple-Case Study, Camille M. Lund

All Graduate Theses and Dissertations, Fall 2023 to Present

Though research on effective mathematics instructional strategies is robust, there remains a gap between research and the instruction that takes place in mathematics classrooms. One such effective instructional practice—mathematical student discourse (MSD)—has been extensively researched, but little research has looked holistically at the ecological factors that interact to influence teacher decision-making for this practice. In this qualitative multiple-case dissertation study using Urie Bronfenbrenner’s ecological systems theory as a theoretical lens, I conducted semi-structured interviews with three elementary teachers who teach mathematics in districts across northern Utah. These interviews utilized the researcher-created Ecological Factors Map to explore how teachers described the …

Probing The Roles Of Connexin 43 Hemichannels In A Mouse Model Of Alzheimer's Disease, Madison Treasure-Areno

All Graduate Theses and Dissertations, Fall 2023 to Present

Alzheimer’s disease is a progressive disorder involving neuronal death and cognitive decline, such as memory loss and changes in personality. One feature of the disease is buildup of abnormal protein called amyloid-beta in the brain. Amyloid-beta may activate support cells called astrocytes, triggering them to release large amounts of chemicals, possibly harming nearby cells. This study set out to examine the roles of the channels on astrocytes involved in releasing these chemicals, called connexin 43 hemichannels. Using a mouse model of Alzheimer’s disease, this study blocked the hemichannels using the drug Tonabersat, and measured spatial learning and memory in a …

Dyadic Agreement In And Task Correlates To A Measurement Of Conversational Success, Samantha Budge

All Graduate Theses and Dissertations, Fall 2023 to Present

Successful conversation matters for social connection, wellbeing, and quality of life, but people do not always agree on whether a conversation was successful, even when they participated in the same interaction. Conversation is also commonly measured through task success, even though it’s unclear how task success correlates to how successful a conversation feels. This study examined how conversational success is experienced by different conversation partners and whether feeling successful in a conversation is related to how well a task is completed.

Participants took part in a structured conversational task and then rated their own conversational experience using a self-report questionnaire …

The Rodent Electronic Nicotine Delivery System (Rends): Effects Of Age On Self-Administration Of Inhaled Nicotine In Female Rats, Daniel Santos Da Silva

All Graduate Theses and Dissertations, Fall 2023 to Present

Smoking tobacco is the leading avoidable cause of death and drives many health problems. Nicotine, the main chemical in tobacco products, keeps people using it. This study used the Rat Electronic Nicotine Delivery System (RENDS), an inexpensive and freely shared, to examine e-cigarette use in adolescent and adult female rats by exploring four phases of nicotine delivered and not delivered to understand use patterns among ages. Our study found that both adolescent and adult female rats chose to inhale nicotine when given the opportunity, showing drug-seeking behavior. Overall, nicotine use was similar between ages. These results could help inform therapies, …

Enhancing Evidence-Based Practice Decision-Making Among Practitioners In Adult Disability Service Settings, Aubrey Vance

All Graduate Theses and Dissertations, Fall 2023 to Present

Board Certified Behavior Analysts (BCBA®s) working in adult disability services often face challenges such as high caseloads, limited oversight, and restricted resources, which can make it difficult to use individualized, research-supported interventions. Although evidence-based practice (EBP) is central to applied behavior analysis, many practitioners receive little training on how to integrate research evidence, client values, and clinical judgment into their decision-making. This study examined whether BCBAs could be effectively trained to use a structured decision-making framework based on the EBP model by Slocum et al. (2014). Using a multiple baseline design, we evaluated the effects of Behavioral Skills Training (BST) …
