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 …

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 …

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 …

Entre Irse Y Quedarse: Sociolinguistic Effects Of The H-2a Program In The U.S. And Mexico, Hayden D. Holman

Theses and Dissertations--Hispanic Studies

This dissertation examines stabilized circular migration as a distinct sociolinguistic condition through a study of Mexican participants in the U.S. H-2A temporary agricultural worker program. Whereas much migration scholarship presumes linear settlement and cumulative immersion, the H-2A program institutionalizes repeated cycles of departure and return between specific origin and destination communities. This patterned mobility produces recurrent immersion in an English-dominant environment followed by re-centering in a Spanish-dominant community, creating conditions of cyclical activation and recalibration of linguistic repertoires.

The study investigates two interrelated questions: (1) how sustained participation in stabilized circular mobility shapes participants’ spoken repertoires, contact-induced features, and language …

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 …

Inverse Problems For The Radiative Transport Equation In Local And Non-Convex Geometries, Faith E. Hensley

Theses and Dissertations--Mathematics

Inverse problems for the radiative transport equation (RTE) arise in a wide range of imaging applications, including optical tomography and problems motivated by non-line-of-sight imaging. Classical reconstruction methods rely heavily on ballistic, or unscattered, photons and typically require full boundary access, leading to severe instability and limited applicability in geometrically constrained settings. This dissertation investigates inverse radiative transport problems with restricted boundary data and develops reconstruction techniques based on scattered photons. The central focus of this work is the analysis and isolation of the single-collision term in the collision expansion of solutions to the RTE. By exploiting its distinct analytical …

Local Energy Decay For Non-Stationary Damped Wave Operators, Nicholas Dj Arsenault

Theses and Dissertations--Mathematics

This work establishes integrated local energy decay (ILED) estimates for the damped wave equation on certain non-stationary spacetimes. The main technical result is a high frequency estimate that holds in great generality, provided that null geodesics trapped in a compact region are sufficiently damped. This is combined with low- and medium-frequency estimates to establish full local energy decay. We conclude by providing a counterexample where the damping assumption fails and local energy decay does not hold.

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 …

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, …

Beyond The Veil: Critical Black Kantianism And The Ethics Of Structural (In)Visibility, Paradise A. Stanford

Theses and Dissertations--Philosophy

This dissertation develops what I call Critical Black Kantianism, a reconstructive approach to Kantian moral philosophy that centers race, recognition, and the structural conditions under which moral agency is formed. While Kantian ethics typically presumes idealized agents operating within just social contexts, this project argues that such abstraction obscures how racial domination actively shapes autonomy, dignity, and self-consciousness. Drawing on W.E.B. Du Bois’ account of double consciousness, Black feminist thought, and contemporary theories of recognition, I show that moral agency is not merely exercised within social environments but is constituted through them—often under conditions of misrecognition that fracture autonomy.

Against …

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, …

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 …

Multiphysics Transport In Porous Thermal Protection Systems: Experimental Characterization Of Gas Permeability And Radiative Properties, Yejajul Hakim

Theses and Dissertations--Mechanical and Aerospace Engineering

Porous thermal protection systems (TPS) used in hypersonic vehicles exhibit coupled gas and radiative transport across multiple regimes and length scales. Accurate performance prediction requires reliable characterization of permeability, slip-flow behavior, and radiative transport properties, particularly for low-permeability and charred materials where existing data are limited. This dissertation presents experimental methods for characterizing multiphysics transport in porous TPS materials. A modular flow system was developed to measure permeability and slip behavior in both virgin and charred materials under relevant environments. A transient pressure decay method enables accurate permeability estimation in low-permeability regimes and provides insight into effective pore structure. Results …

Reciprocity-Based Transfer Function Techniques For Acoustic Source Reconstruction, Spring Isolator Characterization And Structural Damping Assessment, David Pum Thian Lal Paite Neihguk

Theses and Dissertations--Mechanical and Aerospace Engineering

Reciprocity implies that a system responds identically when the source and receiver positions are interchanged. This dissertation applies this principle to address three practical challenges in noise and vibration characterization, where conventional approaches are limited by inaccessible interfaces, constrained excitation conditions, or metrics that do not fully capture vibroacoustic behavior.

The first study develops and validates an inverse method to characterize ducted acoustic sources using acoustic free velocity. Acoustic reciprocity is applied to simplify transfer function measurements. The method is extended to large cross-section ducts, where the source is reconstructed as a collection of point sources along a plane. Validation …

Process-Guided Learning Via Data-Driven Modeling And Controller Synthesis, Benton Clark

Theses and Dissertations--Mechanical and Aerospace Engineering

This work introduces process-guided learning, a framework in which process characteristics and learning algorithms are combined in the modeling process of engineering applications with the aim of uniting traditional and data-driven modeling and control techniques. Traditional engineering methods using simplified analytic models fail to capture the increasing complexities of engineering problems with sufficient accuracy to achieve modern requirements. More advanced modeling and control techniques using high-fidelity models often produce a computational burden that is infeasible for real-time solutions. Data-driven modeling offers a simple and flexible algorithm for producing real-time capable, high-fidelity models, but naive implementations lack the physical constraints of …

Molecular Mechanisms And Metabolic Consequences Of Glucocorticoid Resistance, Genesee J. Martinez

Theses and Dissertations--Pharmacology and Nutritional Sciences

Glucocorticoids are vital steroid hormones that govern metabolism, stress responses, and immune functions through intricate, tissue-specific mechanisms, both genomic and non-genomic. These hormones bind to the glucocorticoid receptor (GR), which then acts as a transcription factor to modulate gene expression. Chronic elevation of glucocorticoid levels may lead to glucocorticoid resistance, resulting in adiposity, inflammation, and insulin resistance, thereby adversely affecting multiple metabolic tissues. Whether produced endogenously or administered exogenously, excessive, chronic glucocorticoid concentrations impair glucocorticoid signaling. Although there are two primary isoforms of the receptor, GR⍺ and GRβ, only GR⍺ interacts with glucocorticoids.Through the research conducted in this dissertation, we …

Expanding The Role Of Muscle Stem Cell Fusion In Muscle Under Hypertrophic Stimulus, Jensen Goh Zhong Sheng

Theses and Dissertations--Physiology

Muscle stem cells (MuSCs) are a unique stem cell population that can activate in response to both injury and growth stimuli. Studies on muscle regeneration have shown MuSC activation follows a uniform progression through proliferation, differentiation, and fusion. Therefore, to determine whether MuSC replication is a prerequisite for differentiation under hypertrophic stimulus, I used a lineage-tracking mouse model (Pax7^rtTA; TRE-H2B-GFP) to label MuSC nuclei and simultaneously tracked DNA synthesis via EdU incorporation. This dual-labeling approach allowed us to not only distinguish MuSC-derived nuclei but also demarcate which MuSC had proliferated prior to fusion. I then employed a mechanical …

Breaking The Cycle: Financial Abuse And Mental Health Outcomes Among Women Survivors Of Intimate Partner Violence Through The Abc-X Model Of Family Stress, Angel Martinez-Johnson`

Theses and Dissertations--Family Sciences

The present study examined the relationship between financial abuse and mental health outcomes among women survivors of intimate partner violence (IPV) with particular attention to the roles of perceived financial knowledge and resilience. Guided by the ABC-X Model of Family Stress, this study explored whether these perceived resources function as mediators in the association between financial abuse and symptoms of anxiety, depression, and posttraumatic stress disorder (PTSD). Findings indicated that financial abuse was significantly associated with increased psychological distress across all three outcomes. Although perceived financial knowledge and resilience were significantly related to certain mental health outcomes, analyses did not …

Managing Dietary Nonstructural Carbohydrates In Insulin Dysregulated Horses: Pasture, Long-Stem Forage, And Restrictive Grazing Strategies, Morgan J. Askins

Theses and Dissertations--Veterinary Science

Insulin dysregulation (ID) is a complex endocrine disorder, impacting a large percentage of the equine population. ID is the defining characteristic of equine metabolic syndrome (EMS). Within the various classifications of EMS horses, the commonality is ID and their higher risk of laminitis. To mitigate insulin response and laminitis risk in ID horses, current management focuses on restricting pasture exposure and feeding low nonstructural carbohydrate (NSC) rations. Minimal studies have evaluated how ID horses respond to pasture of various NSC, long-stem forages, and restrictive grazing strategies. Providing horse owners and managers with improved nutritional management recommendations for ID horses with …

Equid Major Histocompatibility Complex (Mhc) Evolution & Genome Organization, Lauren C. Johnson

Theses and Dissertations--Veterinary Science

The evolution of modern horses has a well-documented fossil record and has long been of interest to the genetics community. Although non-caballine equids (e.g. zebras, donkeys, and asses) can hybridize with horses, the resulting offspring are typically infertile. Despite these reproductive barriers, genomic analyses reveal regions of high sequence similarity among equid species. This dissertation investigates the role of historical introgression in the evolution of modern Equus species. The first chapter re-evaluates earlier findings derived from a limited horse population and a single reference genome. The variants of the identified regions were pushed through Ensembl’s Variant Effect Predictor to assess …

Between The Rails: Experiential Education And Its Impact On Compliance And Consistency In Racetrack Surface Management, Heather Mackenzie

Theses and Dissertations--Community & Leadership Development

Recent regulatory requirements within the Thoroughbred racing industry have increased expectations for consistent collection and reporting of racetrack surface data. Despite clear standards, implementation in daily operations remains inconsistent, highlighting a gap between regulation, knowledge, and practice. This study examined the impact of an experiential education curriculum on racetrack personnel’s self-efficacy and reporting consistency.

Using a quantitative design, data were collected through pre- and post-surveys measuring self-efficacy and records of the number of days surface data were entered. Descriptive statistics, paired-samples t-tests, and effect size analyses were used. Results showed a statistically significant increase in self-efficacy (p < .001) with large effect sizes, indicating meaningful gains in confidence and comfortability. Reporting consistency did not show a statistically significant change (p = .885).

Overall, experiential education …

Understanding Knowledge And Perceptions Of The Beef Industry On A Land-Grant University Campus, Allison E. Reaves

Theses and Dissertations--Community & Leadership Development

A well-researched phenomenon in the agricultural industry is the effects of constant innovation coupled with an increasing divide between producer and consumer. This issue has been presented as especially prevalent within animal agriculture and the beef industry, a predominant concern considering Kentucky’s agricultural commodities. This study (n = 31) utilized a mixed-methods approach to understand the knowledge, perceptions, and behavior of beef consumers on a land-grant university campus. Methodologies included Python’s DeepFace emotion recognition, semi-structured interviews, and the JMALI agricultural literacy assessment. Findings revealed participants to be below expected agricultural literacy levels of high school graduates (M=11), with no …

“They Don't Care If I'M Here Or Not”: The Impact Of Exclusionary Discipline On Black Boys In Elementary Schools, Arielle Gulley

DSW Capstone Projects

Disproportionate and exclusionary school discipline practices continue to affect African American boys as early as elementary school, with significant implications for their mental health, academic engagement, and long-term educational trajectories. This capstone project examines how racially biased discipline contributes to disparities in belonging, emotional well-being, and student-teacher relationships, and advances the need to reframe discipline as a site of mental health intervention rather than punishment.

The systematic literature review synthesizes peer-reviewed research to examine the relationship between exclusionary discipline and mental health outcomes among African American boys in elementary settings, with particular attention to patterns emerging in early educational environments. …

Establishing An Advanced Practice Provider-Led Transient Ischemic Attack Clinic: A Quality Improvement Initiative, Brittany A. Young

DNP Projects

Background: Due to lack of subspecialized neurological care in many rural community settings, care in tertiary hospitals is in demand. Insufficient care pathways can lead to lack of bed and provider availability. Advanced Practice Provider Transient Ischemic Attack clinics have been shown to be safe alternatives to hospital admission, for patients who meet criteria. This study targeted practice change at a 1000 bed tertiary academic hospital.

Methods: The quasi-experimental study sample inclusion criteria included Transient Ischemic Attack patients presenting to the emergency department with an ABCD2 < 4, complete symptom resolution, and no new cardiac changes on monitoring. A pre and post survey with educational PowerPoint intervention was provided to all emergency department and Neurology providers and nurses. A Transient Ischemic Attack clinic was established with a corresponding order set to be utilized for streamlined outpatient work up.

Results: During the pilot period, 29 admissions were deferred with 69% …
