Resting-State Functional Connectivity Of Dopaminergic Reward Pathways Across The Adult Lifespan, Julia Cardarelli

Theses and Dissertations

This study investigates the effect of age on three major dopaminergic reward pathways using resting state functional magnetic resonance imaging. Resting state imaging refers to low-frequency brain connectivity in the absence of task demands or directed thought patterns. The pathways included in this thesis are as follows: the nigrostriatal, mesolimbic, and mesocortical pathways. These pathways rely on dopamine and are known for a variety of functions, most notably regulating responses to rewarding and aversive stimuli. This analysis compared the connectivity between key regions of interest, where transmission originates in the midbrain and substantia nigra, and terminates in the orbitofrontal cortex, …

Beyond The Binary: Examining The Impact Of A Restorative Justice Intervention On Administrator Perceptions And Disciplinary Disparities For Black Male Students, Arianne A. Booker

Theses and Dissertations

For decades, black students have experienced educational inequalities, particularly when it comes to academic achievement and school discipline. The purpose of this mixed-methods study was to investigate the factors leading to the racial discipline gap among Black male students in middle schools. Black males face more punitive consequences that often result in exclusionary practices than their peers. This problem is due to cultural differences between teachers and students, where teachers’ subjective interpretations of behavior—such as disrespect or defiance—lead to removal from the general education classroom. The theoretical framework that guided this study was Critical Race Theory and Culturally Responsive Teaching. …

Inclusive Postsecondary Education Practices & Staff Beliefs Related To Parent Engagement, Abigail Mojica

Theses and Dissertations

Inclusive postsecondary education (IPSE) programs for youth with intellectual and developmental disabilities (IDD) are expanding across the United States, yet research on parent engagement in these settings remains limited. This study examined current practices related to parent engagement within U.S. IPSE programs and investigated whether specific staff and program characteristics were associated with variations in engagement. A national sample of IPSE program leaders (N = 106) completed an online survey assessing staff demographics, program features, and parent engagement activities. The survey was developed for this study, informed by literature on secondary transition, IPSE programs, and parent engagement in both K–12 …

An Examination Of Gendered Experiences In Undergraduate Engineering Education With Emphasis On Participation, Validation, And Persistence, Madison Lynn Burlett

Theses and Dissertations

This study investigates gendered experiences in undergraduate engineering education, with particular attention to academic validation, participation, and belonging. While prior research suggests disparities in retention and representation, these patterns are often examined through quantitative metrics such as grades, self-efficacy, or survey- based perceptions. Such approaches can provide limited insight into how students interpret and navigate engineering environments in practice. This study adds to the existing body of research by examining students’ lived academic experiences through qualitative analysis.

Semi-structured interviews were conducted with undergraduate engineering students across multiple disciplines and academic levels. Interviews elicited detailed accounts of how students approached academic …

A Vision-Language Model Framework For Geographically And Environmentally Informed Soundscape Assessment, Pengyu Chen

Theses and Dissertations

Sound environments shape how people experience urban spaces, yet conventional noise monitoring relies on isolated sensors that lack semantic context and spatial scalability. This study explores whether Vision-Language Models (VLMs) can infer acoustic conditions directly from street-view imagery, offering a scalable alternative to dense sensor networks. This thesis focuses on three tasks: (1) identifying visible sound sources (vehicles, pedestrians, water features); (2) predicting sound pressure levels (SPL) in decibels; and (3) classifying sound type into Natural, Mechanical, or Human categories. I collected 200 field samples across 11 cities using mobile phones and decibel meters, producing aligned image-spectrogram-dB triplets spanning diverse …

The Relationship Between Members’ Characteristics And Their Group Cohesion Perceptions In A University Band Program, Andrew M. Connolly

Theses and Dissertations

Scholars have labeled group cohesion the most important construct to consider when studying group dynamics and often describe it as the result of factors that attract members to the group and encourage their continued involvement. Generations of researchers have studied group cohesion in sports teams and military units, but few have examined the construct in music education. The purpose of this study was to examine the relationship between collegiate wind band members’ (N = 45) characteristics and their perceptions of group cohesion within their ensembles. I conducted this quantitative, non- experimental study to examine relationships between demographic factors (major and …

The Graduate Piano Student With Adhd: Learning And Practicing With Ongoing Challenges In Executive Function, Molly Alyse Thomas

Theses and Dissertations

Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders in the United States. According to the DSM-5-TR, ADHD is characterized by inappropriate levels of inattention, hyperactivity, and impulsivity. It is widely considered a disorder for children and adolescents, however, there is a growing number of adults receiving an ADHD diagnosis in adulthood. Because of this later diagnosis, it is unlikely that adults with ADHD have developed effective coping strategies for management of daily responsibilities. While ADHD symptoms create challenges for individuals with ADHD, deficits in Executive Functioning (EF) are one of the foremost contributors to issues with personal, …

Reading The Criminal Mind: Victorian Pseudoscience And The Fear Of Degeneration In “The Strange Case Of Dr. Jekyll And Mr. Hyde”, Abigail Jasa Sommer

Theses and Dissertations

This paper argues that Robert Louis Stevenson’s The Strange Case of Dr. Jekyll and Mr. Hyde (1886) functions as a gothic critique of late-Victorian pseudoscience and the cultural desire to make morality legible on the body. Situating the novella amid phrenology, physiognomy, criminal anthropology, degeneration theory, and evolutionary psychology, it shows how scientific discourse circulated beyond professional institutions to shape popular assumptions about deviance, identity, and social order. Through Jekyll’s experiment and Hyde’s emergence, Stevenson stages the collapse of the “scientific gaze”: Hyde appears to confirm the period’s criminal typologies, yet his deformity remains simultaneously undeniable and indescribable, exposing the …

Supporting Stem Self-Efficacy Using Culturally Relevant Pedagogy For Historically Underserved Black Female Students, Rajdeep Young

Theses and Dissertations

The underrepresentation of Black women in science, technology, engineering, and mathematics (STEM) fields remains a persistent concern in education and the workforce. Research suggests that students’ beliefs about their ability to succeed in STEM, referred to here as STEM self-efficacy, may play a critical role in shaping STEM interest, persistence, and career pathways. Grounded in Bandura’s self-efficacy theory and informed by Culturally Relevant Pedagogy and Intersectionality, this study examined the impact of a targeted intervention designed to support and strengthen STEM self-efficacy among Black middle school girls. Using a mixed-methods approach, the study investigated changes in participants’ STEM self-efficacy following …

Rethinking Career-Pathway-Based Programs In Career Technical Education Utilizing Improvement Science, Michael J. Parry

Theses and Dissertations

Career technical education (CTE) has traditionally been organized around distinct career pathways designed to develop deep technical expertise within a single occupational field. While this model has been effective in preparing students for entry- level employment, it increasingly limits students’ opportunities to develop transferable technical and professional skills that span multiple pathways—skills now essential in a dynamic, interdisciplinary workforce. This dissertation in practice examined how a career technical education system could redesign pathway-based programming to support cross-pathway skill development while preserving pathway-specific technical rigor.

Guided by improvement science, this improvement work was conducted at Grant Career Center (GCC), a rural …

Thank You For Being A Friend: Exploring Positive Peer Influence In Black Friendships Toward Academic And Social Success, Trini Victoria Woods

Theses and Dissertations

In this focus group study the researcher interviewed seven Black, Title I high school students to understand their experiences with positive peer influence within their friendships. In an effort to present a counternarrative to the majoritarian narrative that Black students are operating at a deficit and need policing, this research provides insight to the academic and social experiences of participants positive peer influence. This research responds to three questions: what do Black students believe is meaningful in friendship and how do they describe the impact of positive peer influence; how do Black students feel their friends’ behaviors and attitudes influence …

You Want A Fight? You Found It: Amplifying High School Students’ Voices To Combat Book Banning’S Silencing Effect, Alicia Sue Weaver

Theses and Dissertations

As a high school English teacher in South Carolina, I was concerned about the silencing of teachers and students through book banning, which limited students’ agency and threatened their perceptions of themselves and others. This mixed-method, embedded-design, action research dissertation tells the story of my effort to resolve this problem of practice and provides recommendations to practitioners facing similar challenges. To better understand the root of the problem, I examined research related to policy, self-censorship, loss of teacher autonomy, and harmful rhetoric. The theoretical framework grounding this study came from two primary lenses: treating literature as windows, mirrors, and sliding …

Teaching English As A Living Language: An Action Research Study Of Communication And Learner Confidence, David Lawrence Brian Levy

Theses and Dissertations

This action research study examines the disconnect between language learning in schools and the ability to use the language as a communication tool. Unfortunately, many educational institutions teach language with an emphasis on grammar rules, written exams, and rote memorization instead of as a living language used for everyday communication. This results in students receiving grades which do not reflect their ability to speak the language effectively. The purpose of this study was to explore how instructional practices influence both students’ communicative competence and confidence levels. It also intends to examine ways to redesign classroom instruction to better support real-world …

Exploring The Efficiency Of Logistic Models With Opt-Out Designs In Discrete Choice Experiment And Their Applications, Dai Fang

Theses and Dissertations

A discrete choice experiment is usually conducted in economics background to measure how consumers would like to trade off attributes of a product, service, or policy. In this experiment, respondents are provided different hypothetical combinations of varied components by using an experimental design such as the full factorial design, which fully represents the all combinations of attributes and levels. The mathematical background of a discrete choice experiments is based random utility theory, in which either positive or negative values are given each characteristic and the weighted sum values of each choice given in the experiment will be compared. This experiment …

Examining Role-Play Simulation Effectiveness In Reducing Student Skill Gaps In An Interpreter Education Program, Nicole Nadine Morris

Theses and Dissertations

The purpose of this mixed-methods action research study was to identify students’ skill development in an interpreter education program using authentic role-play simulations. Three research questions guided this study. Two questions guiding the quantitative data collection centered on skill development during foundational interpreting courses and through the practicum semesters. The third research question guided the qualitative data collection, which focused on the participants’ perceptions of the usefulness of the role-play simulations in preparing them for their practicum placements. Together, the data indicate that the simulations provide significant benefits for students in interpreter education programs in terms of their professional readiness. …

Between What’S Promised And What’S Lived: Lgbtq Former College Athletes’ Experiences At Inclusive Institutions, Alyssa Morgan Edlin

Theses and Dissertations

Despite the increased visibility of lesbian, gay, bisexual, transgender, and queer or questioning (LGBTQ) inclusion in college sports, it remains unclear whether athletes find these environments truly safe, supportive, and able to live authentically. Institutional evaluations and rankings often focus on policies and public commitments, offering limited insight into how inclusion is experienced in everyday athletic settings. Consequently, little is known about whether institutions labeled as inclusive actually foster environments where LGBTQ athletes feel a sense of belonging, authenticity, and meaningful support.

Rooted in an interpretivist-constructivist paradigm and guided by narrative inquiry (Clandinin & Connelly, 2000), this study examines the …

Breast Cancer Communication For Young Women: Exploring Narrative Games As Vehicles Of Transportation, Adetutu Oluwaseyi Wande-Kayode

Theses and Dissertations

Despite extensive intervention efforts, breast cancer remains the most common cancer among women in the United States and the second leading cause of cancer-related deaths in women. Prior research in breast cancer communication has largely focused on older women, yet early-onset breast cancer among younger women (ages 18-39) has increased in recent years. This trend highlights an urgent need for tailored communication strategies to improve young women’s understanding of breast cancer risk factors, prevention, detection, treatment, and survivorship. The present study developed and tested a digital narrative game based on the Health Belief Model, as a potential tool to enhance …

From Boca Chica To Mars: Spacex, Desubjectification And The Making Of Expendable Futures, Iwalewa Oluwajuwonlo Olorunyomi

Theses and Dissertations

This project examines how SpaceX’s development of Starbase Boca Chica Beach in Brownsville, Texas, produces what I call desubjectified futures: the systematic transformation of residents from subjects who imagine and create futures into objects upon which futures are imposed. Drawing on five weeks of ethnographic fieldwork, including interviews with residents, environmental justice organizers, and members of the Carrizo/Comecrudo Tribe, I argue that SpaceX achieves hegemony not simply by manufacturing consent but through an ontological operation that strips communities of the capacity for collective self-determination before consent becomes meaningful.

I trace this process through three interrelated modes. First, discursively, how SpaceX …

The African Sky And The Human Spirit: Ethics, Exile, And Women In Saint-Exupéry And Camus, Snezana Popova

Theses and Dissertations

This dissertation offers a comparative study of Albert Camus and Antoine de Saint- Exupéry, focusing on their representations of women and the ethical visions that emerge through them. While Camus is often associated with the philosophy of the absurd and Saint-Exupéry with transcendence and spiritual hierarchy, this study argues that both writers articulate a shared moral humanism grounded in responsibility, solidarity, and fidelity to human presence. The figure of the woman—whether as mother, beloved, or silent moral witness—becomes a crucial site through which these ethical commitments are revealed.

Through close textual analysis of major works—including La Mort heureuse, L’Étranger, La …

El Mal, Miedo, Y Caos Urbano: El Neogótico Latinoamericano En El Siglo Xxi Como Estrategia Para Analizar La Violencia Transpolítica En La Narrativa De Mario Mendoza, Andrés Felipe Arroyave

Theses and Dissertations

This dissertation examines how the core concern of Mario Mendoza’s work is the notion of evil and how the Latin American neogothic genre provides an apt framework for its exploration. His narrative exposes the eruption of evil, fear, and psychological terror in urban life, portraying a chaotic and desolate Bogotá. Mendoza’s novels conceive evil as an internal human condition that emerges in the minds of both protagonists and secondary characters, becoming a mirror of the city’s social reality. The study analyzes Satanás (2002), Diario del fin del mundo (2018), and Akelarre (2019) to show how these works articulate emotions such …

The Mountains Call: Escaping To Zones Of Seclusion, Alec Lee Parry

Theses and Dissertations

The biographical and thematical overlap between the literature of Austrian authors Ingeborg Bachmann and Thomas Bernhard, and Swiss writers Max Frisch and Fleur Jaeggy, is established in literary scholarship. However, similarities in the role Alpine spaces play in their works remain unaccounted for. The Alps represent a cultural and geographical boundary between linguistic identities and international borders. Protagonists across this dissertation’s three chapters face internal crises, prompting them to move to “zones of seclusion.” Within these “zones of seclusion,” characters spark discussions of collective memory even if they are isolated themselves. These peripheral locations force recollection, often on collective memory, …

The Role Of Parenting Factors On Moderating The Effects Of Parent Perceived Stress On Waist Circumference And Family Mealtime Outcomes In Black Adolescents With Overweight And Obesity, Taylor Ryan White

Theses and Dissertations

Family mealtime is a protective factor for adolescent health outcomes (e.g. well-being, diet quality); however, parent stress may diminish the frequency and quality of family meals and increase obesity risk through physiological (e.g., allostatic load) and behavioral (e.g., decreased physical activity (PA), obesogenic diet) pathways. Parenting factors, like responsive parenting (e.g., providing support for adolescent healthy eating) and feeding practices (e.g., parental monitoring - tracking adolescent diet), may mitigate the effects of parent stress by promoting adolescent behaviors (e.g., nutritious eating, increased PA) that are linked with healthier weight outcomes; however, few studies have examined this in Black families. Therefore, …

Understanding Spanish Language Patterns In Therapy: Insights Into Therapists, Clients, And Session Characteristics, Vanessa Perez

Theses and Dissertations

Spanish-speaking individuals face significant barriers to accessing linguistically appropriate mental health services. Language match between therapists and clients has been associated with positive impacts on the therapeutic process; however, little is known about how Spanish is used in youth therapy sessions or how therapeutic and demographic characteristics influence its use. Using 54 recorded Spanish-speaking therapy sessions from a randomized controlled trial of school-based mental health services in Los Angeles, California, this study sought to understand who participated in these sessions, how Spanish was used, and what predicted its use. To address these aims, data were drawn from electronic health records, …

Maternal Reading Skills And Child Mortality In Nigeria, Kayode Ibraheem

Theses and Dissertations

Although, child mortality in Nigeria has declined significantly over the past three decades, the country still has one of the highest rates in the world. The inverse relationship between maternal education and child survival is well established, but the mechanisms by which education impacts mortality remain underexplored. This study assessed the mediating effect of maternal literacy in the relationship between child mortality and maternal education, extending prior work that focused primarily on mothers with low education levels. Using the data from the 2018 Nigeria Demographic and Health Survey, I analyzed 24,865 mothers who had at most secondary education as well …

Supporting Retention Of Special Educators: A Comparison Study Of Perspectives And Experiences Of Special Education Teachers, Mary Margaret Stahl

Theses and Dissertations

The shortage of special education teachers and providers is a significant concern across the United States. This research study further examines the factors which effect special educators and how this can differ based on the service delivery model and category of disabilities taught by teachers. To date, no previous studies have examined special education teacher and provider retention by service delivery model and this study addresses that gap. By examining retention across service delivery models, these findings can inform implications for both practice and further research. This study helps expand the literature and move the field from identifying what matters …

Bridging The Gap In First Grade: Community Perceptions Of Standards-Based Grading And Literacy Communication In A Rural Virginia School Division, Kristin Janssen

Theses and Dissertations

This qualitative action research study explored the perceptions of parents, guardians, and teachers regarding standards-based grading (SBG) in first-grade literacy instruction and examined community buy-in toward its implementation in a rural Virginia school district. Although state-level mandates such as the Virginia Literacy Act emphasize evidence-based literacy instruction and foundational reading skills, traditional grading practices remain common in early elementary classrooms. These practices often lack alignment with instructional standards and may obscure students’ literacy progress, creating challenges for communication between schools and families.

Surveys with closed and open-ended questions yielded data from first- grade teachers and parents or guardians to illuminate …

A Tail Of Consumption: Essays On Pet-Person Identities And Their Effects On Consumers, Mackenzie Micheala Volk

Theses and Dissertations

This work examines how exposure to pet-person identities — identifying as a dog person or a cat person — affects consumer behavior. Across two chapters, results show that exposure to dog-person cues increases preferences for bold and conspicuous product features through heightened desire for dominance-based status signaling. Additionally, exposure to cat-person cues activates a cat-person mindset, boosting support for inclusive businesses and policies by increasing minority support and justice sensitivity. Together, these findings suggest that subtle identity cues in the marketplace can meaningfully shape consumer preferences and social attitudes, with implications for how brands position themselves and how policymakers and …

The Metacognitive Shift: Reshaping Student Attitudes And Adaptive Reasoning Through Error Analysis In Eighth-Grade Mathematics, Samantha Lynn Graves

Theses and Dissertations

This study utilized an action research framework to address students’ lack of adaptive reasoning skills in a mathematics classroom in South Carolina. These students often focus on procedural fluency without understanding the reasoning behind the steps. Using a mixed methods design, this study examined the impact of implementing student- led error analysis as a metacognitive strategy on the adaptive reasoning skills and attitudes of 20 eighth-grade mathematics students. The study took place over 6 weeks at a Title I public charter school, and the intervention required students to identify, correct, and explain errors in various problem types, including fractions, applied …

Instructional Design To Support Math Identity Growth In Middle School, Sarah A. Foster

Theses and Dissertations

Middle school mathematics classrooms often emphasize performance and correctness in ways that contribute to negative student beliefs, disengagement, and persistent underachievement, particularly among students enrolled in on-grade-level courses. In this action research study, a targeted math identity development intervention was implemented to examine how instructional practices designed to affirm student thinking influenced eighth-grade students’ math self-efficacy, growth mindset, academic performance, and self-perception as mathematics learners. The study also explored teachers’ perceptions of student identity shifts and the instructional strategies they viewed as most effective in fostering positive math identity.

Guided by Bandura’s theory of self-efficacy, Dweck’s growth mindset theory, and …

Quality Of Life As A Guiding Construct For Service Delivery In Applied Behavior Analysis, Aaron Randall Check

Theses and Dissertations
