From Barriers To Breakthroughs: Academic Advising And Resilience Among Online Social Work Students In Appalachia, Jessica Williamson

DSW Capstone Projects

This Doctor of Social Work (DSW) capstone project examines how academic advising can be leveraged as a resilience-informed intervention to support persistence among online social work students in the Appalachian region. Although online education has expanded access to higher education, Appalachian students continue to face significant structural, technological, and cultural barriers, including limited broadband access, financial instability, geographic isolation, and norms that emphasize self-reliance. These challenges contribute to lower retention and degree-completion rates, highlighting the need for intentional, context-responsive support strategies. This project integrates three scholarly products: a systematic literature review (SLR), a conceptual paper, and a practice application paper. …

Hardin Health Link: A Community-Integrated Paramedicine (Cip) Program In Hardin County, Kentucky, Samantha Jones

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Rural and mixed rural–urban communities face persistent disparities in access to timely emergency medical services (EMS), contributing to preventable morbidity and mortality from time-sensitive conditions such as cardiovascular disease, stroke, and injury. Hardin County, Kentucky, reflects these challenges due to its geographically dispersed population, high burden of chronic disease, and variability in EMS response times. This capstone proposes Hardin Health Link, a Community-Integrated Paramedicine (CIP) program designed to expand the traditional role of EMS providers through in-home health assessments, chronic disease monitoring, post-discharge follow-up, medication reconciliation, and connection to clinical and social services.

Guided by an evidence-informed framework, the program …

Promoting Maternal And Infant Health In Franklin County, Ky: A Community-Based Physical Activity And Education Intervention, Subin Kim

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Maternal and infant health outcomes are key indicators of population health, yet persistent disparities exist in rural communities across the United States. In Kentucky, Franklin County reflects this pattern, with concerning maternal and infant health indicators despite relatively favorable socioeconomic conditions. Identified challenges include elevated rates of poor physical and mental health days, high drug overdose mortality, provider shortages, and ongoing reproductive health concerns such as tobacco use during pregnancy and increased infant mortality associated with elevated maternal body mass index.

To address these gaps, a three-pronged, community-based prenatal and postpartum physical activity and education program is proposed. The program …

Momentum For Healthy Births-Hardin County, Ky, Brittany R. Jackson

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Maternal and infant health disparities in Hardin County, Kentucky, reflect persistent gaps in timely access to care, particularly among rural and underserved populations. Structural barriers, including transportation limitations and unmet social needs, contribute to delayed prenatal care initiation and low postpartum follow-up, increasing the risk of adverse outcomes. This capstone project proposes the MOMentum (Maternal Outreach and Monitoring for Mothers) Program, an integrated care model designed to strengthen access, improve care coordination, and enhance continuity across the prenatal and postpartum period.

The program combines a Community Health Worker (CHW)-led navigation model with enhanced postpartum care supported by telehealth services and …

Implementation Of A Reminder/Recall Messaging Program In Kentucky, Laura Schwarz

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Childhood vaccination remains a critical public health priority, yet measles, mumps, and rubella (MMR) vaccination rates in several rural Kentucky counties fall below the 95% threshold required for herd immunity. Recent declines in coverage, compounded by socioeconomic disparities and barriers to healthcare access, place children at increased risk for vaccine-preventable diseases and outbreaks. This capstone project proposes the implementation of an evidence-based reminder/recall (R/R) text messaging intervention utilizing the Kentucky Immunization Registry (KYIR) to improve timely MMR vaccination among children aged 4–6 years before kindergarten entry.

The proposed program targets thirteen Kentucky counties with vaccination rates below 70% and documented …

Strengthening Rural Mental Health Crisis Response: Integrating Broadband Telehealth Care Across Counties Served By Kentucky River District Health Department, Mary K. Mcnabb

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Rural communities in Eastern Kentucky face persistent barriers to timely and effective mental health crisis care, including provider shortages, transportation challenges, and limited broadband infrastructure. Counties served by the Kentucky River Health Department Wolfe, Lee, Owsley, Perry, Knott, Leslie, and Letcher experience disproportionately high behavioral health needs while relying on shared regional resources. The Broadband-Enabled Rural Crisis Stabilization Initiative (BERCSI) is a proposed public health program designed to strengthen rural mental health crisis response through integrated, technology-enabled care. Grounded in evidence-based practices, including tele-mental health and crisis stabilization models, BERCSI leverages broadband expansion to facilitate rapid assessment, coordinated care, and …

Zero Tolerance Or Strong Cultural Diversity: The Hard Case Of Female Genital Surgery, James M. Donovan, Christiane Canant

Law Faculty Scholarly Articles

This article applies a thesis favoring strong cultural diversity to defend a subject-centered policy regarding female genital surgeries (FGS). That idea posits that cultural variation holds an intrinsic value that should be presumptively respected when setting policy and creating law. Correlatively, cultural homogenization, especially by force, should be resisted. 

Taking as a starting point the recent celebration of the United Nation’s Day of Zero-Tolerance for Female Genital Mutilation, the paper reviews the context of FGS practices in various societies and critiques the inconsistencies of U.N. arguments to advance its goal of total elimination by 2030. Especially problematic for the U.N. …

In Vivo Telemetry To Record Long-Term Cardiovascular Parameters, Temperature, And Activity In Spinal Cord Injury Rat Models, Sajeev Kaur, Anna M. Baur, Jillian A. Condrey, Dorottya P. Gal, Samir P. Patel, John C. Gensel

Spinal Cord and Brain Injury Research Center Faculty Publications

Higher-level spinal cord injury (SCI) above thoracic level 6 (T6) disrupts autonomic function and contributes to secondary complications, including fluctuations in blood pressure, heart rate, and temperature. In rats, the placement of telemetric implants in the descending aorta offers a robust methodology for assessing various cardiovascular parameters, such as systolic and diastolic pressure, mean arterial pressure, and heart rate. Core body temperature and animal activity can also be recorded following telemetric implant placement. A rat with a telemetric implant is kept on the receiver plate connected to a computer system for recording various parameters. Continuous long-term recordings at defined time …

Preventing Teen Pregnancy Through Expanded Contraceptive Access In Mccreary County, Kentucky, Dacey B. Chitwood

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

This capstone project proposes a school-based Condom Availability Program to reduce teen pregnancy risk by expanding discreet contraceptive access for adolescents in McCreary County, Kentucky. Teen pregnancy remains a persistent public health concern in rural communities where stigma, privacy concerns, transportation barriers, and limited healthcare access can prevent adolescents from obtaining reproductive health resources. McCreary County faces elevated teen birth rates, socioeconomic disadvantage, and limited maternal healthcare infrastructure, making teen pregnancy prevention an important local priority. The proposed program would place free latex and non-latex condoms in student restrooms at McCreary Central High School, with QR-code-linked information connecting students to …

Community Place Attachment As A Significant Correlate Of Motivation To Change Substance Use Behavior Among Adults Who Inject Drugs In Rural U.S., Janet K. Otachi, Shawndaya S. Thrasher, Keith J. Watts, Juma S. Mwenda, Hilary L. Surratt

Social Work Faculty Publications

Introduction: While motivation is critical for substance use disorder (SUD) recovery, many individuals fail to engage in treatment. The need to belong is a fundamental human motivation, yet the role of community place attachment (CPA) as a social asset in fostering motivation to change substance use behaviors (MCSUB) among people who inject drugs (PWID) is understudied. This paper examines the effect of CPA on PWIDs’ MCSUB.

Methodology: Cross-sectional data were collected from 350 PWID recruited from syringe service programs in rural Appalachian Kentucky (2018–2021). We used hierarchical multivariable linear regression to assess the association between CPA and MCSUB, controlling for …

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 …

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 …

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, …

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 …

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 …

On Stripping And Antipodes In Motivic Steenrod Algebras, Joshua A. Peterson

Theses and Dissertations--Mathematics

We generalize the stripping process to the (mod 2) $\mathbb{C}$- and $\mathbb{R}$-motivic settings. Throughout, we include discussion on how the process changes and the difficulties moving to more general settings. We also introduce antipodes and consider what a potential $\mathbb{R}$-motivic analogue may look like. Finally, we elaborate on how the results may be used in future work to generalize a nilpotence result of Walker and Wood.

Extensions Between Modules Defined By Lattice Paths In The Preprojective Algebra, Chloe Napier

Theses and Dissertations--Mathematics

In 2001, Fomin and Zelevinsky introduced cluster algebras which appear as coordinate rings of many varieties. We study cluster algebras coming from Richardson varieties. Leclerc gives a cluster structure on Richardson varieties using the representation theory of preprojective algebras. While this construction is very algebraic, we take a more combinatorial approach. The main goal is to find a combinatorial description for when certain cluster variables are compatible, or equivalently when modules defined by lattice paths in the preprojective algebra have trivial extensions. We extend the known results from Geiss, Leclerc, and Schröer that answer this question in the case of …

A Character Theory For Loop Representations Of Symmetric Monoidal Bicategories, Jordan Sawdy

Theses and Dissertations--Mathematics

Character theory arises in many distinct fields of mathematics, but its many instantiations often share a few key features: they arise in contexts where one object is acted on or parametrized by another, and they are often computed via "trace-like" formulas. Focusing on these properties, we present a categorical formalism for constructing such characters. We first define a notion of "loop representation" for symmetric monoidal bicategories, then build a character for such representations via the canonical symmetric monoidal trace. We then show that this character defines a symmetric monoidal functor which satisfies commutativity properties with respect to both restriction- and …

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 …

Combinatorial Models For Nonnegativity In Flag Varieties, Williem L. Rizer

Theses and Dissertations--Mathematics

The nonnegative Grassmannian admits a widely studied cell decomposition due to Alexander Postnikov, whose cells are indexed by positroids and modeled by several equivalent combinatorial objects. Subsequent work by authors including Lauren Williams, Suho Oh, and Carolina Benedetti has further developed the combinatorics and geometry of these structures. In this dissertation, we extend some of Postnikov’s combinatorial framework to the nonnegative flag variety. While cell decompositions in this setting were previously obtained, notably in work of Konstanze Rietsch, our focus is on providing new combinatorial models that make this structure more explicit and computationally tractable. We introduce flag positroid pipe …

The Interaction Between Additive And Multiplicative Structures In Arithmetic Settings, Ali Alsetri

Theses and Dissertations--Mathematics

The first part of this thesis is concerned with Goldbach-type problems. In recent years, there has been an interest in developing density versions of Goldbach-type results. Namely, given a relatively dense subset A of the primes, one may study representations of integers as sums of primes belonging to the subset A. These density Goldbach-type results have been facilitated by the development of new tools from additive combinatorics, in particular the Fourier-analytic transference principle due to Green. We apply the transference principle to obtain a variant of Vinogradov’s theorem involving subsets of primes confined to the residue class 1 (mod 3). …

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.

Understanding Möbius Inversion As Composite Of Dual Pairs, Isaac B. Kochmaan

Theses and Dissertations--Mathematics

Möbius inversion is a well-studied computational tool in number theory and combinatorics, but it exhibits a pattern which may be familiar to those who study categorical traces. In 2016, Kate Ponto and Michael Shulman characterized duality and traces in the bicategory of profunctors for a particularly nice class of one-cells. We extend these results. Consequently, we construct, for a given poset, a profunctor whose Euler characteristic is the Möbius function of said poset. In light of this, we propose a categorical notion of Möbius inversion.

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 …

Exploring The Limitations Of Substrate Scope In Dimethylallyltryptophan Synthases, Evan T. Miller

Theses and Dissertations--Pharmacy

Natural products (NPs), are the largest source of bioactive compounds in Nature, and are essential to the treatment of human disease. Nearly 50% of drugs approved for use from 1981 to 2019 owe some aspect of their development to NPs, either in terms of their structure, pharmacophore, or mechanism of action. However, NPs are difficult to structurally optimize. Chemoenzymatic methods for NP derivatization have been increasingly seen as practical alternatives to traditional synthetic methods. Prenyltransferases (PTs) are involved in the primary and secondary metabolism of plants, bacteria, and fungi, and they are key enzymes in the biosynthesis of many clinically …

Validation Of Final And Dynamic Subsidence Prediction Models Using The Influence Function Method, Carlos M. Hernandez Garcia

Theses and Dissertations--Mining Engineering

This study evaluates the Surface Deformation Prediction System (SDPS Version 7) for predicting final and dynamic subsidence in longwall mining. Using the influence function method, SDPS 7 was calibrated using data from the Quarto 7 Mine (Ohio, USA) and two panels in Anhui Province, China, to test the reliability of the method under varying geological and operational conditions, particularly low advance rates.

For the Quarto 7 Mine, monument line C provided the optimal set of subsidence parameters: SSF of 78%, tanβ of 2.97, edge‑effect offset of 160 ft, with an RMSE of 0.108 ft. These values aligned with estimates obtained …
