Problem-Based And Practice-Driven: Designing For Engagement In An Online Educational Leadership Program, Owens G. Saylor

Theses and Dissertations--Educational Leadership Studies

Virtual professional learning has emerged as a flexible and scalable solution for developing educational leaders, particularly those navigating demanding roles and geographic barriers. However, these benefits often come at the cost of diminished engagement, interaction, and practical application to real-world leadership challenges. Without intentional design, virtual sessions risk becoming passive and disconnected, undermining their professional development value. This study responds to these challenges by exploring how a problem-based learning (PBL) approach can improve engagement in the virtual component of the Kentucky Leadership Rising (KLR) Aspiring Superintendent Workshop Series.

This mixed methods action research (MMAR) study examined participants’ perceptions of engagement …

From Trauma To Triumph: The Relationship Between Psychological Resilience And Academic Resilience In Graduate School Students With Adverse Childhood Experiences, Jade Gingue

Theses and Dissertations--Educational Leadership Studies

This dissertation investigated the relationship between adverse childhood experiences (ACEs), psychological resilience, and academic resilience among graduate students. Grounded in resilience theory and interpreted through a trauma-informed, strengths-based lens, the study examined whether psychological resilience functions as a buffering moderator or as a direct protective factor among graduate students.

Using a quantitative design, data were collected via Qualtrics from graduate students (n = 391). This study used three previously validated instruments, including the Adverse Childhood Experiences Questionnaire (ACE-10), the Connor-Davidson Resilience Scale (CD-RISC-25), and the Academic Resilience Scale (ARS-6), along with demographic measures. Hierarchical multiple regression analyses were conducted …

Recruitment Messaging, Authenticity, And Representation: A Mixed Methods Action Research Study In A Public School System, Chavis A. Sims

Theses and Dissertations--Educational Leadership Studies

This study employed a Mixed Methods Action Research (MMAR) design to examine recruitment communication within a public school system facing persistent underrepresentation of minority educators.  Recruitment prototypes were developed in collaboration with district leadership and evaluated in a formative pilot involving 15 educators who provided Likert-scale ratings and written feedback on clarity, cultural relevance, persuasiveness, and engagement.  Quantitative findings indicated that messaging emphasizing professional purpose and pathways into teaching was perceived as clear and engaging.  In contrast, cultural relevance consistently received the lowest ratings across prototypes.  Qualitative responses revealed that reliance on non-local and AI-generated imagery weakened perceived authenticity and …

Responding To The Needs Of First-Generation Students: An Action Research Study Of Professional Development Opportunities For Faculty And Staff, Kyle G. Phillips

Theses and Dissertations--Educational Leadership Studies

First-generation college students have historically been considered marginalized in institutions of higher education, with diminished success rates and disproportionately higher incidents of imposter syndrome. This Mixed Methods Action Research study assessed the extent to which faculty and staff are able to recognize and implement research-based best practices to improve the support system surrounding this student demographic. In particular, it assessed current levels of preparation to support first-generation students and sought to identify and implement an appropriate professional development program as part of the study's intervention. The efficacy of the intervention was then assessed, with the result delineated in this dissertation. …

Enhancing International School Implementation Capacity: Supporting Contextualized Learning At An International Baccalaureate School In China, Christopher J. Hayden Iv

Theses and Dissertations--Educational Leadership Studies

International schools allocate substantial resources to implement progressive curricular innovations; however, the advantages offered by these developments are contingent on their effective execution within classroom settings. This mixed methods action research (MMAR) study examined the implementation of the International Baccalaureate (IB) Global Context (GC) Strategy in the Middle Years Programme (MYP) at an international school in China and asked how the school might strengthen its capacity to enact this and similar innovations. Following a sequential MMAR design, a reconnaissance phase combined a whole-staff survey (n=87) with qualitative interviews to diagnose the individual, organizational, and contextual factors shaping implementation. Analyses identified …

Unveiling The Shadows: An Exploratory Study On Ghostwriting, Gray Markets, And The Ethics Of Contract Cheating, Micah Crawford

Theses and Dissertations--Educational Policy Studies and Evaluation

Contract cheating has become an increasingly complex challenge for higher education, particularly as digital platforms, global academic labor markets, and generative artificial intelligence reshape the production and detection of academic work. While much of the existing literature examines contract cheating from the perspectives of students, faculty, and institutions, less attention has been given to the individuals who produce ghostwritten academic work. This dissertation addresses that gap by exploring how shadow scholars understand their roles, ethical boundaries, and participation within the academic integrity ecosystem.

Using an exploratory qualitative design, this study draws on twelve semi-structured narrative interviews with six freelance academic …

Perceptions Of Sport Psychology Efforts And Access In Women's Wheelchair Basketball, Lindsay C. Cohen

Theses and Dissertations--Kinesiology and Health Promotion

As the field of sport psychology grows, services and training programs must evolve to properly serve the evolution of athletes seeking care. This could mean discovering new measures, testing different types of interventions, or developing programs that can better accommodate specific populations that are looking for sport psychology services. One such population is para athletes, and although they have expressed interest in learning more about the field of sport psychology and how to implement mental skills efficiently, athletes have reported a lack of access to sport psychology services and sport psychology consultants (SPCs) (Dieffenbach et al., 2009). The purpose of …

Test-Retest Reliability And Validity Of The Gas Exchange Threshold, Erik Ryan Snell Mr.

Theses and Dissertations--Kinesiology and Health Promotion

Theoretically, the gas exchange threshold (GET) demarcates the moderate and heavy intensity domains, whereby exercise performed at and below the GET results in a change in oxygen consumption ([ΔVO₂] ≤ 200 mL), and exercise above the GET results in a slow component (ΔVO₂ > 200 mL). This study examined the reliability and validity of the GET. 14 subjects performed two maximal graded exercise tests (GXTs) to determine the GET and its reliability. The minimal difference (MD = 21W) was applied to determine the GET above (GET_+MD) and below (GET_-MD) power outputs for 30 min …

Biomechanical Effects Of Exercise-Based Interventions In Chronic Nonspecific Low Back Pain: A Systematic Review And Meta-Analysis, Lara De Vecchi Machado

Theses and Dissertations--Kinesiology and Health Promotion

Chronic nonspecific low back pain (CNLBP) is the leading cause of years lived with disability worldwide and represents a complex, multifactorial, and heterogeneous condition. It is characterized by substantial interindividual variability in muscle activation patterns, lumbo-pelvic coordination, and movement strategies. Although exercise is widely recommended as a first-line intervention and its clinical benefits are well established, the biomechanical mechanisms underlying functional improvement remain fragmented in the literature and are rarely synthesized quantitatively.

This dissertation conducted a systematic review with meta-analysis to investigate the biomechanical effects of exercise-based interventions in individuals with CNLBP. A total of 39 studies were included and …

Noninvasive Optical Assessment Of Tissue Hemodynamics In Preterm Infants And Mastectomy Skin Flaps, Samaneh Rabienia Haratbar

Theses and Dissertations--Biomedical Engineering

Adequate tissue blood flow and oxygenation are essential for maintaining cellular viability and normal organ function. Disruptions in microvascular perfusion and oxygen delivery contribute to ischemia- and hypoxia-related diseases, including stroke, cancer, retinopathy of prematurity (ROP), and mastectomy skin flap necrosis. Reliable, noninvasive approaches for assessing tissue hemodynamics are therefore critical for improving diagnosis and therapeutic decision-making, particularly in settings where conventional methods are limited. This dissertation investigates the clinical and physiological importance of measuring tissue blood flow and oxygenation across neonatal and surgical applications using both clinical monitoring and advanced optical imaging techniques. In the first study, high-speed pulse …

Theses and Dissertations--Education Sciences

Leadership practices within NCAA Division I athletic departments can shape the professional climate, well-being, and stability of the coaching staff. Yet, limited research has explored how senior administrators influence the experiences of coaches who lead women’s teams at mid-major institutions. This phenomenological inquiry study explored how head coaches interpret their interactions with senior athletic department staff and how these relational dynamics inform perceptions of support.

Twelve Division I head coaches participated in semi-structured Zoom interviews about their experiences at former institutions. The interview protocol integrated the LMX-7 framework with open-ended questions to capture the significance of the head coaches’ lived …

Effects Of Yoga And Mindfulness On Emotional Regulation, Behavior, And Teacher Burnout, Sara E. Smith

Theses and Dissertations--Education Sciences

This dissertation comprises three studies that examine the effects of physical activity, yoga, and mindfulness interventions on students' emotional regulation, behavior, and academic outcomes in rural Kentucky schools. These studies as a whole contribute to understanding how movement-based and mindfulness practices can enhance social-emotional and academic well-being in schools.

The first study describes the effects of classroom-based physical activity on student achievement and social-emotional well-being. Forty-five elementary students participated in a 6-week intervention with two 7-minute movement breaks per day. Results indicated statistically significant improvements in Reading (t(44) = 2.55, p < .001, d = .38), Math (t(44) = 4.63, p < .001, d = .69), and social-emotional competence (t(44) = 3.67, p < .001, d = .55). These findings demonstrate that brief, structured physical activity can meaningfully enhance academic and emotional outcomes when implemented by classroom teachers.

The second study shows the effects of a five-week …

Mental Health And Help-Seeking In Engineering Education: Beliefs, Norms, And Intervention Pathways For Undergraduate Students, Matthew D. Whitwer

Theses and Dissertations--Chemical and Materials Engineering

Engineering education is at a critical juncture where supporting student mental health is essential for fostering persistence, equity, and the development of a resilient and innovative workforce. While engineering students experience high levels of distress and low rates of mental health treatment seeking (known as a mental health treatment gap), there is a gap in knowledge around how this compares to that of students in other fields of study. Further, while efforts have been made to improve the mental health treatment gap in engineering, they are limited by a lack of actionable, theory-based targets. Therefore, this dissertation aims to characterize …

A Specification-Driven Framework For Self-Supervised Learning In Specialized Vision Domains, Mahmut S. Gokmen

Theses and Dissertations--Computer Science

Self-supervised learning (SSL) has emerged as a principled approach to visual representation learning that derives supervisory signal directly from unlabeled data, enabling foundation models to be trained at scale without manual annotation. Deployments in medical imaging and biometric recognition have demonstrated the potential of this paradigm, yet the assumptions that make SSL effective on natural image benchmarks fail systematically in specialized domains. Generic SSL pipelines encode a tacit assumption that the most informative correspondence is spatial proximity within a single acquisition. In specialized domains this assumption breaks at the level of the data-generating process: the signal that carries domain-specific information …

Are Multiple-Choice And Open-Ended Assessments Consistent In Predicting Science Achievement? Multivariate Multilevel Evidence From Chinese Students And Schools, Quan Wu

Theses and Dissertations--Education Sciences

A multivariate multilevel model was developed and applied to secondary data from a large-scale science assessment of Grade 8 students in China to examine the consistency between multiple-choice and open-ended formats of assessment in predicting science achievement at the student and school levels. The sample included 44,534 students from 159 schools across two regions. Multivariate multilevel results indicated a moderately positive consistency between the two formats at the student level and a strongly positive consistency at the school level; these consistencies were stable across regions and did not depend on student and school characteristics. The findings have important practical implications …

From Mandate To Meaning: Designing Implementation Supports For Organizational Readiness In Behavioral Health Service Planning, Lauren K. Mergen

Theses and Dissertations--Education Sciences

Behavioral health agencies often struggle to translate the Transformational Collaborative Outcomes Management (TCOM) framework into practice when implementation is externally mandated. This study examined how educational leaders can support meaningful use of TCOM tools under a Midwestern state’s October 2024 requirement that behavioral health providers use the state Child and Adolescent Needs and Strengths assessment in service planning.

Using a Mixed Methods Action Research design, the study progressed through six phases: Diagnosis, Reconnaissance, Planning, Acting, Evaluation, and Monitoring. The Diagnosis Phase identified a knowledge-to-practice gap and weaknesses in implementation support infrastructure. Practitioner surveys administered immediately after training and six months …

The Ache Of Modernism: Death, Affect, And Intersubjectivity In Twentieth-Century American Literature, Alex Gergely

Theses and Dissertations--English

This dissertation suggests that we can locate, describe, and experience death as an aesthetic mood called the ache of modernism. The ache is an atmosphere found in twentieth-century literature that goes beyond simply “positive” or “negative” feeling and encourages audiences to come to an affective and existential relationship with their mortality. As an intersubjective mood deriving from an attunement on death, it illuminates the historical and philosophical moment of many twentieth-century authors while clarifying their texts’ continued resonance today. This project therefore draws on the thought of major philosophers like Emmanuel Levinas, Martin Buber, Gabriel Marcel, Maurice Merleau-Ponty, Heidegger, …

In The Flesh, Isabella Mason

Theses and Dissertations--English

IN THE FLESH is a nonfiction collection by Bell McEntire Mason, in which she illustrates a life dominated by the corporeal, embodied, and incarnate experience of physicality. Consisting primarily of personal essay, lyric essay, and flash nonfiction, the collection follows a journey of bodily understanding and acceptance that braids itself with the author’s life experiences, ranging from battles with mental health and physical illness to tender and painful relationships with family to looming acknowledgement of a body’s temporary status.

Other Eyes: The Dilemma Of Authorship And Autobiography In Sylvia Plath, John Ashbery, And Cristina García, Kevin J.B. O'Connor

Theses and Dissertations--English

This dissertation analyzes authorship in contemporary American literature, harnessing the writings—prose and poetry—of Sylvia Plath, John Ashbery, and Cristina García to challenge traditional classification and periodization schema. Hewing to the notion of authorship as a dilemma—a simultaneity of forces pressing upon the author, demanding a response—each chapter unravels critical moments of authorial expression that continually inscribe the importance of praxis and futurity. Comprehending authorship as a relational dilemma to be brooked, and indeed, overcome in a panoply of gestures, frees it theoretically from the perils of prior models by drawing attention to authorship’s agential and multi-modal aspects. Melding archival research …

Shakespeare’S Martyrs And The Poetics Of Transformation, Robert Keim

Theses and Dissertations--English

At the beginning of William Shakespeare’s career as a playwright, England’s most widely read book, after the Bible, was Acts and Monuments of These Latter and Perilous Days, commonly known as John Foxe’s Book of Martyrs. Foxe’s martyrological literature, along with the inherently theatrical nature of martyrdom itself, helped the lives and deaths of Reformation martyrs to assume a prominent place in England’s literary consciousness. Shakespeare was not immune to their influential presence, and though overt representations of martyrdom were too controversial for the popular stage, he did enrich his plays by endowing certain characters—through imagery, allusive diction, …

Sylvia Plath, Ted Hughes, And The Question Of The “True” Ariel: Complicating Binaries In Plath’S Literary Legacy, Jacob C. Quinn

Theses and Dissertations--English

This thesis aims to complicate common binaries that have defined critical responses to Sylvia Plath’s Ariel since its first publication in 1965, and which emerged as the result of her husband Ted Hughes’ alterations to her original selection and arrangement of poems. Hughes’ editing emphasizes a narrative which ends in bleak fatality, whereas Plath’s original narrative concludes on a note of bittersweet hope. I read Hughes’ choice of ending as highly influential on Plath’s reception and legacy. The tone of her immediate reception, largely shaped by Al Alvarez, characterized Plath as an “extremist” poet whose work should be read through …

We Need To Care About Care: (Un)Caring Relations In Victorian Fiction, Roslyn Fleming

Theses and Dissertations--English

The professionalization and institutionalization of care in the Victorian era ushered in a growing societal concern about the pitfalls of care being “systematized and depersonalized” and treating people as burdens, problems to be solved. Given the increasing attention paid to people’s welfare and well-being during this period, the cultural shift from intimate community care to professional and institutional care, and the growing stigmatization of disabled bodyminds, the fiction produced amidst these cultural changes makes a compelling site for a study of care. Critical scholarship attending to Victorian novels’ representations of care, however, has largely concentrated on specific categorizations of care …

Benjy's Personhood In The Sound And The Fury, Addison D. Tighe

Theses and Dissertations--English

This thesis will take a look at the way Benjy Compson’s character in William Faulkner’s novel The Sound and the Fury can be used to form an anti-eugenic argument. By taking a close look at the historical context of America’s twentieth century eugenic movement, the ways in which the novel presents an argument of personhood for those with disabilities come forth despite the eugenic pressures of the time. By taking the time to closely read Benjy’s section within the novel, a mix of disability studies and feminist disability studies, and understanding the complexity of character and stream of conscious writing, …

Role Of Estrogen Receptor Alpha In Modulating The Circadian System In Female Mice, Victoria Alvord

Theses and Dissertations--Biology

Circadian rhythms are approximately 24-hour cycles of physiology and behavior. Circadian rhythms of eating, or meal timing, are linked to cardiometabolic dysfunction in humans. Mistimed eating, such as breakfast skipping and eating late at night, increases the risk of obesity, diabetes, and cardiovascular disease in humans. Likewise, disrupted eating rhythms cause obesity in mice. This dissertation investigates how estrogens regulate eating behavior rhythms and tissue clock timing in female mice. Chapter 1 reviews three key components critical to this work. The first is an overview of the field of chronobiology and the function of the circadian system. The second is …

Understanding The Drivers Of Marine Sediment Diagenesis In Carbonate-Bearing Sediments, Alex Reis

Theses and Dissertations--Earth and Environmental Sciences

Marine sediments serve as an important geochemical record used to study how the Earth’s climate and oceans have changed throughout geologic time. As such, it is critical to understand how these sediments can be altered following deposition on the seafloor. This dissertation targeted two key geochemical archives, carbonate and pyrite, to link changing burial conditions with the resulting marine sediment chemistry. In particular, primary carbonate minerals record several indicators of past ocean chemistry, while pyrite preserves information related to the redox state of the sediment during deposition and burial. Additionally, secondary processes associated with changes in pore fluid chemistry and …

Use Of Stable Isotope Geochemistry To Determine The Paleoenvironment Of The Pond Creek Coal Bed, Pike County, Eastern Kentucky, Vivian A. Edwards

Theses and Dissertations--Earth and Environmental Sciences

Wetlands are both critical habitats and bellwethers of the health of the environment. Coal, being the remains of wetlands, offers the possibility of understanding the evolution of wetlands over large climatic shifts. The paleoenvironment of coals can be determined from palynology, petrology, and geochemistry. Stable isotope ratios within coal, including carbon (δ¹³C), nitrogen (δ¹⁵N), and sulfur (δ³⁴S), are established tools for paleoenvironmental reconstructions. These ratios can be correlated to flora, geochemistry, macerals, and bacterial activity. However, carbon, nitrogen, and sulfur have given conflicting results in some studies and their correlation to known variables is …

Inside The Box: Containerization And The Limits Of Trade Unionism In The International Longshoremen's Association, 1945-1977, Calvin Horning

Theses and Dissertations--Geography

The International Longshoremen’s Association (ILA), the union of dock workers on the East Coast of the United States, saw a dramatic change in form and fortune in the middle of the 20^th century as the shipping industry and global labor underwent an immense reorganization. In the context of this reorganization, I argue that due to internal conservatism and racism alongside external state pressure, the ILA moved from an unruly, mafia-ruled union to a highly organized, professionalized, well-paid core of workers that served to support the United States’ capitalist-imperialist project.

Through archival material spanning over three decades, I analyze the …

(En)Counter Cartographies: Data Collection, Interpretation, And Visualization In Lexington’S Urban Forest, Claire Hilbrecht

Theses and Dissertations--Geography

This thesis examines how urban forestry data practices shape relationships between people, trees, and knowledge in Lexington, Kentucky. Drawing on political ecology, science and technology studies, and critical making, it argues that conventional methods of data collection, interpretation, and visualization privilege Western scientific and market-based frameworks that often exclude affective, embodied, and more-than-human ways of knowing. Using autoethnography and six semi-structured interviews with urban forestry professionals, the study explores how practitioners experience tensions between treating trees as measurable commodities and engaging them as relational beings. It finds that while urban foresters rely on dominant discourses such as ecosystem services to …
