Electronic Theses and Dissertations

This dissertation explores the integration of multimodal data streams and artificial intelligence pipelines to understand human affect in neurotypical and children with Autism Spectrum Disorder (ASD). This dissertation captures human affect in the context of human-robot interaction. For this, multiple studies have been presented with both children with ASD and neurotypical adults. This dissertation makes four contributions: 1) The first study introduces autonomy during perspective-taking teaching sessions by making verbal content generation through large language models (LLMs). This system is the first of its kind for teaching perspective-taking in a semi-autonomous manner under the supervision of domain experts. Furthermore, this …

"I Never Really Saw Anybody That Looked Like Me In A Book": A Positioning Theory Analysis Of Preservice Teachers' Critical Reflections., Melissa Lee Zipper

Electronic Theses and Dissertations

The purpose of this qualitative case study is to understand how preservice teachers develop their criticality within a semester long undergraduate course focused on children’s literature. This study addresses a well-documented practical knowledge gap in education research: although preservice teachers claim to understand the importance of a culturally relevant and sustaining curriculum, they do not know how to effectuate that curriculum when it comes to their future classrooms. Using Positioning Theory as a theoretical lens and an analytical tool, the study explores how preservice teachers position themselves in relation to developing their criticality through participation in a course curriculum purposefully …

Teacher Perspectives On A Teacher Mentorship Program And Its Influence On A Sense Of Belonging And Professional Growth., Hyun Kang Wilson

Electronic Theses and Dissertations

Teacher retention is crisis in the U.S. and globally. Literature suggests the first five years of teaching is a crucial time range to determine if teachers stay in the profession or quit. Teachers will leave the profession due to lack of support, poor school culture, feeling isolated, high work-related stress, poor compensation, and challenging student behaviors. Research suggests that new teacher mentorship programs are effective in addressing teacher support, ultimately improving teacher retention. Literature also suggests that employees are more likely to stay with a company if they feel belonged. To explore the further into a new teacher mentorship program …

“Nothing Can Prepare You For It”: An Interpretative Phenomenological Analysis Of The Lived Experiences, Well-Being, And Relational Connections Of First-Time Mothers Navigating Intensive Mothering Ideals And Expectations., Mona A. Dajani

Electronic Theses and Dissertations

Becoming a mother is a life-changing experience that alters how mothers view and experience their emotional, familial, occupational, and relational worlds. As mothering stories tend to be underrepresented and largely absent from the field of social work, this qualitative study utilized Interpretative Phenomenological Analysis (IPA) to center the voices of eleven first-time mothers navigating a culture of intensive mothering ideals and expectations. As a result, the main research questions of this study are: 1) What are the lived experiences of mothers navigating a culture with deep-rooted intensive mothering expectations and ideals? 2) How is well-being experienced and described in the …

Affective Teacher Tok: A Sociomaterial Analysis Of Teachers’ Digital Literacy Practices On Social Media., Jessica Nicole Gottbrath

Electronic Theses and Dissertations

Mass media often depicts teachers in oversimplified terms, as heroic saviors or dangerous agents of indoctrination, flattening the complex realities of their daily work and lived experiences. This polarization contributes to the ongoing deprofessionalization of teaching, where educators’ expertise is increasingly questioned and politicized. In response to these reductive portrayals and the everyday pressures of the profession, some teachers have turned to short-form social media videos as a creative outlet to share personal and professional insights. To explore how teachers reclaim agency through their digital literacy practices, this study employs mixed-methods research to investigate how educators use networked microvideos to …

Everything And Nothing Found In The House Of Leaves: A Multiliterate Analysis Of Multimodal Writing., Jennings Collins

Electronic Theses and Dissertations

The postmodern horror novel House of Leaves engages in a bevy of discourses across the humanities, a complex work that invites readers to engage with several multimodal forms of reading and writing to experience it fully. This thesis hopes to explore the novel’s place in various sites of discourse including film theory, philosophy, and horror genre theory; applying a multiliterate perspective to the work to study how the novel encourages multimodal and multiliterate thinking by applying studies of typography, experimental literature, and literary ontology. This thesis will emphasize a filmic analysis of text-within-text The Navidson Record, to address a …

Genetic Influence Of Allelic Variation On The Phenotypic Variability Of Cognitive Outcomes In Individuals With Williams Syndrome., Marinie P. Joseph

Electronic Theses and Dissertations

Williams syndrome (WS) is caused by a rare microdeletion of 25 – 27 genes on chromosome 7q11.23, characterized by a distinctive cognitive profile with considerable phenotypic heterogeneity. However, the genetic factors underlying this phenotypic variability remain unclear. I explored two genetic mechanisms—parent-of-origin (PoO) effects and genome-wide polygenic variation, as measured by polygenic scores (PGSs)—to elucidate possible influences on cognitive variability in WS. The first study examined PoO effects on cognitive abilities in two overlapping samples of children with WS (N = 211, N = 251). PoO refers to which parental homolog of chromosome 7 contains the WS deletion. Despite …

Black Women Under The White Gaze: Resistance From Enslavement To Incarceration And Reentry., Barbie C. Parker

Electronic Theses and Dissertations

Black women in the United States who are currently incarcerated or have previously served time in prison have a particular need for protection as they move through the criminal “injustice” system because they frequently act as the primary caregivers for their families. Consequently, Black female convicts have historically had to create their social networks inside and outside carceral spaces as a form of resistance to white supremacist ideologies and as a site of protection. By highlighting Black women’s history of enslavement and incarceration, the different forms of resistance, and centering their narratives, we can paint a more complex picture of …

Perceptions Of Unstructured Recess And Classroom Behaviors In Elementary School Settings., Allison Shockley

Electronic Theses and Dissertations

The priority on core curriculum areas such as math and reading has resulted in limited physical activity and regular recess routines. With the increased time spent on core curriculum, teachers and administrators have shifted their focus towards standardized student testing achievement. This focus has resulted in limiting or doing away with unstructured recess with the hopes that students will gain more core curriculum knowledge. This dissertation will focus on educators' perceptions of elementary school student behavior with varying recess time structures. This study began by examining the history of recess while analyzing the trickled- down historical inequities elementary students experience …

Volatile Organic Compounds And Their Relation To Sympathetic Activation And Autonomic Balance In Humans., Cameron Kyle Stopforth

Electronic Theses and Dissertations

Cardiovascular disease (CVD) is a multifaceted pathology that affects almost half of Americans ≥20 years old. One modifiable risk factor associated with CVD is air pollution exposure. The intricacy of air pollution exposure and CVD can make it difficult to elucidate on the multitude of mechanisms underpinning these associations. In this dissertation, we selected a relevant exposure (i.e., volatile organic compounds (VOC)) and an intermediate outcome (i.e., autonomic balance) that may represent one of these pertinent mechanisms. We tested the central hypothesis that higher VOC exposures would lead to increased sympathetic activation and autonomic imbalance. Aim 1 (Chapter III …

Advancing Speech Intelligibility Assessment: Comparing School-Based Speech-Language Pathologists, Laypersons, And Speech Recognition Software., Hannah Stewart

Electronic Theses and Dissertations

This non-experimental study utilized a convenience sample (N = 86) to investigate the comparability of school-based speech-language pathologists (SLPs), laypersons, and speech recognition software in the assessment of speech intelligibility for children with phonological disorders. Eighty-nine percent of participants were female, and 92% were white. All participants completed a survey comprised of 25 audio recordings of single-word utterances from an AI-generated voice of a four-year-old male with a phonological disorder and were asked to select what word they believed was heard from a pool of 12 options. The survey also included a passage read by the same AI-generated voice, and …

Predicting Confidence In Performing Mental Health Actions Among Allied Professionals., Jean Marie Zelenko

Electronic Theses and Dissertations

One in five young people before the age of 25 exhibit onset of symptoms of an emotional or behavioral disorder (Kessler et al., 2005). Up to 80% of depressed youth do not receive services (Kataoka, 2002) and less than 50% of the time youth seek help for suicidal ideation and/or self-harm (Michelmore & Hindley, 2012). This high prevalence of mental health distress and low frequency of help-seeking among youth require examination of factors influencing youths’ likelihood of seeking help. One factor that increases the likelihood of help-seeking is encouragement from others to seek mental health services (Cusack et al., 2004). …

The Impact Of Consensus Decision Making On Creating Conditions For Psychological Safety In Sbdm Councils., Rachel Ann Klein

Electronic Theses and Dissertations

This study reflects an examination of the forces and factors that impact effective decision-making on a Site-Based Decision Making council (SBDM) in Kentucky. It explores the relationship between consensus decision-making, the leader of a school, and the stakeholders who sit on an SBDM council as it relates to members’ feelings of inclusion, value, and belonging. A qualitative case study was designed to capture observational data gathered during SBDM meetings, as well as data gathered during member interviews. This data was analyzed through a relativist theoretical lens, which revealed that when open, trusting relationships are established among council members, decision-making flourishes. …

Mental health outcomes among collegiate student-athletes, has become a broader concern in the 21^st century. This study examines prevalence and incidence of anxiety and depression amongst student-athletes at the University of Louisville from 2019-2023 across different Sports Groups. The prevalence of anxiety was found to be 20.22% and risk of anxiety was 15.65%. The prevalence of depression was found to be 13.11% and risk of depression was 18.75%. Logistic regression was used to estimate the association between sports groups and anxiety/depression. There was a borderline association between sports groups and prevalence of anxiety after confounder adjustment (OR=1.86, 95% CI: …

Student Perceptions Of School Climate And Safety After The Collective Trauma Of Covid-19 And Racial Injustice Syndemic., Amy Catherine Lyons

Electronic Theses and Dissertations

For people in marginalized communities, particularly the Black and African American community, the combined, disproportionate damage and loss from of the pandemic and a cacophony of racial injustices offer cause for labeling the phenomenon a syndemic. Syndemic is defined as “a conceptual framework for understanding diseases or health conditions that arise in populations and that are exacerbated by the social, economic, environmental, and political milieu in which a population is immersed” (Singer et al., 2017, p. 881). The purpose of this study is to explore, describe, and analyze Kentucky students’ perceptions of school climate and safety by demographic groups, racial …

Cns-Specific Hiv Reservoir Characterization In Humans: Advancing Our Understanding Through Novel Genomics Methods., Ghazal Sadri

Electronic Theses and Dissertations

The persistence of the human immunodeficiency virus (HIV) reservoir despite years of suppressive antiretroviral therapy (ART) represents the principal obstacle to achieving a functional cure. Because the intact, replication-competent portion of the reservoir drives viral rebound after treatment interruption, HIV cure strategies must specifically identify and target cells harboring these proviruses. Conventional reservoir‐characterization techniques typically require separate assays to capture integration sites, assess proviral integrity, and quantify clonal proliferation and they rely on short‐read sequencing. These limitations hinder our ability to understand how integration landscapes, the integrity of the HIV genome, and cell‐division dynamics intersect to maintain viral persistence in …

A Sacrifice On The Altar Of Unity: The Loss Of Black Identity In The Unification Of Kynett And Lagrange First Umc., Rebecca Sue Wishnevski

Electronic Theses and Dissertations

This study examines the 1996 merger of Kynett United Methodist Church, a historically Black church, and LaGrange First United Methodist Church, a traditionally White church in LaGrange, Kentucky. The study provides insight into nonurban Black churches, showing that while they may have smaller congregations in smaller towns, the Black church remains central to Black life and connection like its urban contemporaries. Methods for collecting primary source material relied heavily on oral histories performed by the researcher with Black and White individuals attending said churches and their experiences during the merger. The study reveals that although unification promised a modern building …

Temperament And Screen Time Into Adulthood, Kareem Barbis

Electronic Theses and Dissertations

The possible correlation between language skills, temperament, and screen time in adulthood is understudied. It was hypothesized that high effortful control scores and low childhood screentime would corelate with higher cognitive reflection scores and higher language skills. Using a correlational design, 162 participants were studied (M age = 19.17 years old, 80% female, 86% White, 6% Hispanic). Participants completed an adapted version of the Adult Temperament Questionnaire (Evans & Rothbart, 2007), Cognitive Reflection Test (CRT; Fredrick, 2005), the Cognitive Reflection Test 2 (CRT-2; Thompson & Oppenheimer, 2016), Thompson & Oppenheimer, 2016), a childhood screen time questionnaire, a bilingualism questionnaire, and …

Investigating Exoneration Patterns Among Juveniles, Kristin Mahan

Electronic Theses and Dissertations

Exoneration from crime has been studied among adults, but exoneration of juveniles (i.e., persons under age 18) has not been analyzed as a separate entity, despite distinct legal systems and developmental considerations. Wrongful conviction, while not always indicative of innocence, devastates lives of convicted individuals and their families, while increasing public mistrust and sometimes failing to convict truly guilty individuals. This devastation, as well as vulnerability to wrongful conviction, is significantly increased for youth who miss out on crucial developmental years, milestones, and opportunities.

In the current study, I examined differing and intersecting contributors (i.e., individual characteristics, crime characteristics, legal …

Movement Ecology Of Sandhills Chub, A Carolina Endemic, Zachary Adam Ramsey

Electronic Theses and Dissertations

Fish movement studies have traditionally focused on species that support commercial and recreational fisheries, but recently more focus has been given to non-game, stream fishes because of their recognized importance in maintaining biodiversity within these ecosystems. Stream fish movement is described as being “restricted” and following a leptokurtic distribution via diffusive spread related to environmental and biological factors. Many studies of stream fish movement ecology in North America have occurred in high-gradient streams with coarse substrate in mountains or in streams of the interior plains. Sandhills streams of the southeastern USA are characterized as warm-water, low gradient, and dominated by …

Heterotopias Of Confinement: Zoo Architecture And The Loss Of Elephant Agency, Clayton Gill Beasley

Electronic Theses and Dissertations

Zoos functions as a site where human-animal relationships are structured through built environments that mediate control and representation. This study examines zoos as heterotopias—spaces where power and surveillance are negotiated between human observers and captive nonhuman animals. While zoos are often framed as spaces of conservation and education, their architectural design reinforces hierarchies of observation and confinement, shaping both human perceptions of nature and the lived experiences of nonhuman animals. This research focuses on Asian elephants as a critical species within this framework, exploring how their captivity illuminates tensions between human-imposed structures and nonhuman autonomy. Drawing from theories of heterotopia, …

Leveraging Ai For Enhanced Multimedia Content Creation: College Students’ Perception On The Innovation, Georgina Amankwa

Artificial Intelligence (AI) has revolutionized multimedia content creation, enhancing efficiency and personalization. However, this rapid evolution has raised concerns about originality and ethical responsibility. This study explored college students’ perceptions of AI in content creation and its implications. Using a mixed-methods approach, the research combined surveys and qualitative insights to analyze how students engaged with AI tools. Findings revealed that while AI streamlined workflows, improved content quality, and boosted audience engagement, concerns about authenticity, intellectual property, and the diminishing role of human creativity persisted. Statistical analyses showed a strong correlation between frequent AI use and perceived benefits, yet ethical dilemmas …

Coalitional Belonging As Praxis: First-Year Writing And Student Community Creation In The Post-Dei University., Kendyl C. Harmeling

Electronic Theses and Dissertations

This dissertation began as a study into how students interpret and engage language and actions from their institutions of higher education which allege to be supporting and supportive of universally diverse, equitable, and inclusive campus community belonging. Occurring within a locally and globally turbid context of exponential and variable challenges to diversity, equity, and inclusion efforts by institutions of power – like those of higher and public education – this dissertation seeks to understand how, within and without institutional support for DEI, students self-sponsor and community-sponsor their ways of knowing and being to claim space for their belonging on campus. …

A Causal Model Of Performance Shaping Factors For Human Reliability Analysis In Manufacturing., Prameet Ranjan Jha

Electronic Theses and Dissertations

Human reliability analysis is a critical component of probabilistic risk assessment, aimed at predicting and mitigating human errors in complex systems. This dissertation develops a novel approach to human reliability analysis in manufacturing by integrating structural equation modeling and Bayesian networks to improve the estimation of human error probabilities. Traditional human reliability assessment methods, such as the Standardized Plant Analysis Risk-Human Reliability Analysis (SPAR-H) and the Technique for Human Error Rate Prediction (THERP), provide structured techniques for estimating human error probabilities. However, these methods often fail to capture the complex interdependencies among performance shaping factors (PSFs), limiting their applicability in …

I'M Still Eating Crayons., Eisey Eisenhardt

Electronic Theses and Dissertations

im still eating crayons serves as a reflection on past events experienced in trying conditions after many years of rumination. The title itself is derived from my childhood inclination towards physically experiencing color and texture via chewing on crayons. An inclination that I still experience today; a wish to chew on what captivates me and break it down over time within, so that I may discover a deeper connection with those objects, ideas, and concepts. Not all made discoveries were victories, nor do they place my conscious in a better position than it was at the height of my past …

Evaluating The Relationship Between Musical Sophistication And Melodic And Harmonic Expectations., Anya Elizabeth Shorey-Smith

Electronic Theses and Dissertations

Expectations help us navigate our environment, especially in familiar contexts. Western tonal music offers one such context where expectations are at play. While implicit musical expectations occur in listeners without musical training, musical training can sharpen expectations. Two primary open questions are investigated here. First, explicit pitch-based expectations for less musical participants have been relatively neglected. Second, general musicality and formal musical training have not been well separated in previous research, making it difficult to understand if sharpening of expectations is associated with training itself or with broader musical interactions. Experiments 1 and 2 adapted an explicit music production task …

Emotion Regulation, Reasoning, And Procedural Safeguards In Politically-Polarized Moral Dilemmas., Alanea Graci

Electronic Theses and Dissertations

Societal disputes often stem from polarized moral dilemmas. Procedural justice and self-determination (PJSD) afforded by societal decision-making processes may influence cooperation and acceptance in these dilemmas. However, moral conviction can sometimes overshadow PJSD, causing morally-opposed individuals to avoid deliberation, become uncooperative, or reject decision outcomes. I conducted two experiments to explore the role emotions (emotion regulation) and procedural safeguards for democratic deliberation (e.g., equal discussion time, rules for civility) play in these situations. I examined the topic of abortion in the U.S. after the Supreme Court’s June 2022 reversal of Roe v. Wade. Undergraduates at a large, urban Midwestern university …

Healthcare Access And Agency In Material Culture: A Specialized Analysis Of Pharmaceutical Artifacts From Louisville’S West End., Sara Marian (Deurell) Ignacio

Electronic Theses and Dissertations

The American Victorian Period of the 1870s to 1920s was a time of significant transitions in medicine. In Louisville, Kentucky, this period saw an influx of Black healthcare professionals and the founding of Louisville National Medical College, the state’s first medical school open to people of color. A number of these professionals lived and/or practiced in the Beecher Terrace study area, which was excavated between 2017 and 2020. Patent medicine brands and archival records were examined qualitatively in order to understand neighborhood and case study household health concerns and consumer choice. Statistical analyses of the medicine bottles recovered during the …

Movement On The Ladder: The Lesbian Avant-Garde In America., Sarah Melloy

Electronic Theses and Dissertations

This project examines the role of the periodical magazine in artistic production of avant-garde ideology, focusing on the ability of print as a medium to distribute poetry, art, literature and discourse of the avant-garde in an underground manner. More specifically, it places the earliest American lesbian periodical, The Ladder, in conversation with the surrealist magazine, Minotaure and the New York Dadaist magazine, Blind Man in order to examine the overlaps in how each publication functioned within their respective movements. I use this positioning to argue that The Ladder is as worthy of scholarly attention as the Surrealist and Dadaist …

Predicting Resilience Among Treatment-Referred Youth With A History Of Trauma Exposure: An Exploration Of Risk And Protective Factors., Prabathi Mandara Gunathilake

Electronic Theses and Dissertations

While many children and adolescents experience negative outcomes following exposure to traumatic events, some demonstrate remarkable resilience. Understanding the factors that contribute to this positive adaptation is essential for developing effective interventions. Using secondary data from 199 treatment-referred youth (ages 5 to 18) with histories of maltreatment, refugee experiences, or military-related trauma, collected between 2016 and 2021 by the Metro Louisville’s Center for Promotion of Recovery and Resilience (CPRR) program, this study examined predictors of resilience in trauma-exposed youth and how resilience is conceptualized across different informant perspectives. Hierarchical multiple regression analyses revealed distinct predictive patterns: for youth, personal strengths …
