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--Civil Engineering

Effective evaluation of safety training is crucial to ensure that learning translates into safe work practices, particularly in high-risk public sector environments. The Kentucky Transportation Cabinet (KYTC) is developing a Safety Academy to enhance hazard recognition, risk management, and safety leadership within the organization. However, the Safety Academy has not yet been implemented, and formal evaluation methods for training have not been established. This study aimed to examine evidence-based training evaluation techniques and develop recommendations for evaluating the KYTC Safety Academy prior to program implementation.

This study employed an applied pre-implementation research design grounded in a comprehensive review of safety …

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 …

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.

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 …

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 …

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 …

Spatial Marginalization Of Emotional Support: Understanding Animal-Human Dynamics Of Care On College Campuses, Aleksandra Craine

Theses and Dissertations--Geography

In 2015 Kearny-Nebraska court case determined that student campus housing is considered a dwelling and is therefore covered by housing antidiscrimination laws. Since then, increasing numbers of students across U.S. campuses applied to bring an emotional support animal to live with them. Emotional Support Animals (ESAs) are defined by the U.S. Department of Housing and Urban Development as “trained or untrained animals that do work, perform tasks, provide assistance, and/or provide therapeutic emotional support for individuals with disabilities.” Persons requesting ESA accommodations usually must provide documentation from a medical provider or therapist. ESAs remain a legally and socially contested category …

Visual Genealogies Of Disability In Mexican Visual Culture, Daniela Calvache Garcia

Theses and Dissertations--Hispanic Studies

Disability in Mexico is a visually constructed category, shaped by a long genealogy of representation in which images of bodily difference actively participate in defining power and the management of all bodies. The discursive forces that define disability as unproductivity reduce body-minds to the service of the economic system, affecting our relationship with death, illness, reproduction, size, youth, and beauty. Across the Mesoamerican visual space, such representations have long unsettled dominant systems of truth about bodies. This dissertation examines how conceptions of disability are produced, negotiated, and reimagined through three historical moments and cultural expressions: Pre-Hispanic Mayan imagery, Mexican colonial …

Una Lima Multicultural: La Cultura Material De Las Mujeres Afroperuanas Durante Los Siglos Xvi Y Xvii, Rebeca Ponce Ochoa

Theses and Dissertations--Hispanic Studies

Uno de los valores más importantes de una sociedad es la cultura adquirida a través del conocimiento, de la tradición y de la historia donde el intercambio de experiencias en la ciudad limeña hizo posible la construcción de una cultura material. Los documentos producidos, adaptados y aceptados a un determinado contexto social refuerzan la identidad, la cultura y la memoria de una colectividad.

Por ello, esta investigación tiene como objetivo analizar los autos de fe y los testamentos de mujeres afroperuanas en los siglos XVI y XVII como parte del material cultural que ayudan a pensar y reconstruir el pasado. …

Economic Inequality And Family Formation In The United States, Elizabeth S. Krause

Theses and Dissertations--Economics

This dissertation evaluates economic inequality and family formation in the United States in three essays. In Essay 1, I estimate the effect of providing subsidized access to immediate postpartum contraceptives on birth spacing and infant health among low-income teen mothers. The intent-to-treat estimates indicate a 20% reduction in the monthly short-interval birth rate among teens 12-14 months after policy enactment. I also find evidence that the policy increased the average interval between births and reduced preterm and low-birth weight births and NICU admission rates. In Essay 2, I provide evidence that single mothers and single women without children are important …

The Rhesus Macaque Model Of Mycobacterium Avium Infection Reveals That Age-Related Disease Is Due In Part To Chronic Inflammation And Lung Microbial Dysbiosis, Ethan G. Napier

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Aging is associated with dysregulated immunity and increased susceptibility to infection, a phenomenon dubbed as immunosenescence and characterized by reduced naïve T and B cell pools, altered innate immune function, and chronic low-grade inflammation. Nontuberculous mycobacterial (NTM) pulmonary disease (NTMPD) is an increasingly relevant chronic lung infection that disproportionately affects older adults (65+ years) and immunocompromised individuals. However, the host factors underlying increased disease severity in aged patients remain poorly defined. Literature suggests that effective control of NTM relies on coordinated innate and adaptive immune responses, particularly macrophage activation and Th1 cytokine signaling. Using a rhesus macaque model that closely …

A Framework For Characterizing The Peripheral Immune Isonome Using Long-Read Single-Cell Rna Sequencing And Its Relevance To Neurological Disease, Patricia Hayes Doyle

Theses and Dissertations--Neuroscience

Long-read single-cell RNA sequencing provides an opportunity to understand human health and disease at isoform resolution, revealing cellular diversity and disease mechanisms difficult to resolve with bulk or short-read methodologies.

Using a modified PIPseq workflow and computational pipeline adapted for Oxford Nanopore (ONT) sequencing, we profiled isoform usage across immune cells, integrating marker expression and isoform discovery, generating the largest long-read single-cell dataset of human immune cells from a single individual to date. We identified non-canonical protein-coding variants of GZMB and CD3G enriched in unexpected cell types. We also discovered novel transcripts from CMC1 and LYAR with cell-type-specific signatures that …

Metabolism As A Regulator Of Sleep And Cortical Activity In Health And Alzheimer’S Disease, Nicholas J. Constantino

Theses and Dissertations--Neuroscience

Metabolic flexibility is essential for maintaining normal physiological function, enabling an organism to sense, flux, utilize, and switch fuel sources in response to changing energetic availability, demand, and cellular needs. Energetic demands are state-dependent, with wake and sleep exhibiting distinct metabolic profiles. Sleep is highly sensitive to changes in metabolism and requires metabolic flexibility to both transition into and maintain sleep stability. Alzheimer’s disease (AD) is increasingly recognized as a disease of altered metabolism yet is often framed as a disease of energetic failure. We instead define AD as a disease of metabolic inflexibility, characterized not by insufficient energy availability, …

Environmental Predictors Of Human Lyme Disease Incidence Across Appalachian Counties In Kentucky, Virginia, And West Virginia, 2000-2019, Karlie D. Rennison

Theses and Dissertations--Epidemiology and Biostatistics

This ecological study examined county-level environmental, landscape, and host-related predictors of Lyme disease incidence across Kentucky, Virginia, and West Virginia from 2000-2019. Lyme disease is an emerging public health concern in the Appalachian region, where geographic expansion and shifting ecological conditions may influence disease risk.

Lyme disease case rates (per 10,000 population) were analyzed in relation to climate variables, land cover metrics, host density measures, and rurality using publicly available data sources. Descriptive and regression analyses were conducted to evaluate associations between candidate predictors and disease incidence.

Substantial geographic variation in Lyme disease incidence was observed, with higher case rates …

Design And Advancement Of Analytical Frameworks For In Vivo Single-Photon Calcium Imaging To Characterize Temporal- And Treatment-Dependent Neural Adaptations To Opioid Exposure And Withdrawal In The Medial Prefrontal Cortex, Alexia R. Alsum Dr.

Theses and Dissertations--Pharmacy

Despite the availability of several approved medications for opioid use disorder (OUD), it remains a significant public health concern characterized by persistent neurobiological adaptations that drive relapse and impede successful recovery. The medial prefrontal cortex (mPFC), a region critical for executive control and decision-making, undergoes pronounced functional changes during chronic opioid exposure and withdrawal, yet the cellular mechanisms underlying these adaptations remain poorly understood. This dissertation aims to investigate longitudinal alterations in mPFC neural activity across opioid exposure and withdrawal using in vivo single-photon calcium imaging and newly developed computational frameworks.

Following standard preprocessing to extract and normalize calcium traces, …

The Immune Hangover: Understanding The Influence Of Alcohol Use, Abstinence, And Post-Abstinence Drinking On Monocyte Plasticity, Madison B. Blanton

Theses and Dissertations--Pharmacy

Alcohol consumption is widespread in the United States, with 80% of individuals aged 12 and older reporting alcohol use and 1-in-4 engaging in risky drinking behaviors. Alcohol misuse heightens susceptibility to infections and delays wound healing, indicating a disrupted immune system. Previous studies show alcohol rewires immune cells, especially monocytes and macrophages, which play critical roles in tissue homeostasis and host defense.

Using a rhesus macaque model of ethanol self-administration, we demonstrate that after 6-months of drinking, monocytes exhibit decreased cytokine production and significant transcriptomic changes, indicating a hypo-inflammatory state. In contrast, 12-months of chronic alcohol use induces hyperinflammatory responses, …

Linking S‑Pillar Empirical Criteria With Boundary And Finite Element Models For Underground Stone Pillar Analysis, Benjamin Diddle

Theses and Dissertations--Mining Engineering

The objective of this thesis is to strengthen the relationship between empirically based stone pillar design methods and two numerical modeling techniques by calibrating boundary element and finite element models to the S‑Pillar empirical criteria and observed pillar behavior in underground stone mines. The first component of the research investigates the displacement‑discontinuity boundary element method implemented in LaModel, quantifying the influence of the lamination thickness and element size on stone pillar safety factor predictions. Results showed that optimal thickness depends on overburden modulus, while larger element sizes introduce significant SF differences from S-Pillar values once the grid size exceeds 5 …

Investigating The Potential Role Of Toxoplasma Gondii In The Development Of Equine Protozoal Myeloencephalitis, Brooklyn Nicole Shirah

Theses and Dissertations--Veterinary Science

Equine protozoal myeloencephalitis (EPM) is a neurologic disease of horses prevalent in the Americas, caused by the coccidian parasites Sarcocystis neurona and Neospora hughesi. Toxoplasma gondii is a related parasite that infects nearly all warm-blooded animals, including horses. Prior studies show conflicting results on whether T. gondii contributes to EPM, in part because no validated T. gondii serologic assay exists in horses. This study developed a recombinant TgSAG1 ELISA and confirmatory Western blot. These assays evaluated T. gondii seropositivity in 789 serum samples from healthy and neurologic horses across multiple geographic regions and examined 31 paired serum:CSF samples for …

Human Resource Policy And Practice In The American Regional Theatre: The Intersection Of The Actors’ Equity Association And The League Of Resident Theatres, Kathleen Holland

Theses and Dissertations--Arts Administration

Human resource management plays a critical yet understudied role in the American regional theatre, an industry characterized by project-based labor, mixed union and nonunion workforces, and deeply ingrained cultural norms that prioritize artistic production over worker well-being. This dissertation examines how institutional human resource policies intersect with the Actors’ Equity Association (AEA) collective bargaining agreement and the League of Resident Theatres (LORT), and the implications of these intersections for human resource practice in regional theatre organizations. While entertainment-industry unions predate the formalization of contemporary human resource management, little scholarship has examined how union agreements may shape or substitute for organizational …
