Spatializing The Tax Code: Using Property Records To Locate The Fiscal Face Of Rentiership, Michael J. Mccanless

Theses and Dissertations--Geography

This dissertation analyzes how the tax code shapes housing financialization in mid-sized US cities. Employing a mixed-methods approach that integrates critical computational analysis with qualitative fieldwork in Memphis, I examine the role of public rent-seeking in shaping housing financialization in U.S. cities. The first article analyzes the property tax appeal strategies of corporate landlords and their implications for public revenues and municipal budgets. The second article explores how the IRS 1031 exchange provision—which allows for capital gains deferrals when the proceeds of a property sale are reinvested in a ‘like-kind’ property—facilitates the movement of capital from high-cost coastal markets into …

The Houston Climate Justice Museum As A Catalyst For Environmental Justice: Exploring The Intersection Of Art, Activism, And Creative Placemaking In Houston, Texas, Aylin Castro

Theses and Dissertations--Geography

This thesis explores how the Houston Climate Justice Museum (HCJM) functions as a site for environmental/climate justice education through art and community engagement. Drawing on interviews, participant observation, and document analysis, this research examines how the museum’s curating practices generate new understandings of environmental in/justices, fosters local partnerships, and creates a welcoming space for community dialogue. Findings show that the HCJM does more than exhibit art, it demonstrates how art can be leveraged to advance both activist and educational projects. This study positions the HCJM as a model for how local and justice orientated museums and cultural spaces can contribute …

Making Slums Legible, Visible And Calculable: Geospatial Technologies And The Governance Of Urban Land In Mumbai, Sanjana Krishnan

Theses and Dissertations--Geography

This dissertation examines how geospatial technologies are used to make slums in Mumbai legible, calculable, and hypervisible, and how these practices reshape urban land governance. It situates mapping, remote sensing, and algorithmic systems within their political-economic contexts, showing how technologies intending to see the city often function as instruments of dispossession. The research has three interconnected empirical chapters. The first empirical chapter traces the history of slum mapping in Mumbai, from their absences in early development plans to their selective hypervisibility under the contemporary governance regimes. Using critical cartographic methods, it highlights how novel technologies such as remote sensing, biometric …

Yaoi Lesbians: Media, Identity, And Desire, Olivia Marquardt

Theses and Dissertations--Linguistics

Media consumption reflects aspects of identity while also assisting in identity formation (Koller, 2008; Zemmels, 2012; Wu, 2006). This thesis examines the phenomenon of lesbians who engage with men-loving-men (MLM) media. The practice seems odd due to the contrast of lesbians desiring women for their social, platonic, romantic, and sexual relationships, but this thesis finds that repeated consumption of media that display men and their desires can index lesbianism. This practice helps lesbians construct their identities through three processes of indexicality: indexical disjuncture, indexical bleaching, and indexical denial (Barrett & Hall, 2024). Through a discourse analysis of five semi-constructed interviews …

Trashing Gender Scripts: Indexical Misrecognition In The Zine "Galatea's Naked", Jules Blank

Theses and Dissertations--Linguistics

Zines, short for ‘fanzines’ or ‘magazines,’ refer to physical, printed, self-published creations that can consist of a single sheet of paper or many, fastened together. These artifacts are rich with meaning—and, thus, can be read as tangible manifestations of the ideologies and identities of the creator(s).

This thesis focuses on the way zines are used as tools of resistance. Additionally, it shows that the creation and circulation of zines are highly pragmatic acts that solidify social bonds and enable individuals to perform and reinforce their emergent identities within a collective—explicitly making a claim about who they are and what they …

Cognate Facilitation And Processing In English-Speaking Learners Of German, Kaitlin L. Young

Theses and Dissertations--Linguistics

Within the field of second language acquisition, research finds that increased exposure to input results in improved proficiency, especially when those activities are challenging yet manageable for the language learner’s current level. Because of this, listening exercises and speech processing are considered integral to language acquisition, even leading to recommendations of frequent, authentic use of the target language (TL). Instructors’ TL authenticity is, however, sometimes stunted by the demand for comprehensible input and facilitation of classroom activities; they make use of simpler syntax, stronger enunciation, and more cognates (words sharing origins, meanings, and form across languages) than in casual speech. …

Hugo Chávez, El Camino Hagiográfico: Religión Y Bolivarianismo En La Construcción Discursiva Del Culto A Un Presidente, Lilia Malavé Conley

Theses and Dissertations--Hispanic Studies

This dissertation examines the discursive construction of the political-religious cult surrounding Hugo Chávez through a theoretical and methodological approach that integrates Critical Discourse Analysis (CDA) and Multimodal Discourse Analysis (MDA). Its central objective is to identify and interpret the incorporation of elements from the Venezuelan religious imaginary–particularly from popular Christianity–into the symbolic configuration of Chávez as a sacred figure within official discourse. The corpus analyzed includes official transcripts from the television program Aló Presidente, as well as two animated short films titled Chávez Nuestro que Estás en el Cielo (“Our Chávez Who Art in Heaven”), broadcast on Venezuelan public …

Paratum Fuit: Double Perfect Marking In Classical Latin Passives, James F. Epperson Ii

Theses and Dissertations--Linguistics

Despite thousands of years of study, certain constructions in Latin remain insufficiently described in modern Latin linguistics. One such construction is the double perfectum, an analytic verbal construction comprising the perfect passive participle and a perfectum forms of the auxiliary esse. These forms are rare, largely absent from educational Latin materials, and receive limited attention in scientific descriptions of Latin, often focusing on their evolution into the modern Romance verbal systems. Pinkster (2015) identifies them within a broader class of resultative constructions, but acknowledges their inconsistent usage. Earlier scholars, such as Riemann (1927), interpreted them as stative, while others, like …

Shaping A City: Municipal Housekeeping, Civic Activism, And Urban Environmentalism In Progressive Era Louisville Through The Women’S City Club, Amy J. Malventano

Theses and Dissertations--History

At the turn of the twentieth century, rapid industrialization and urban expansion transformed American cities, creating urgent challenges in governance, public health, and environmental management. In response, women across the United States extended their domestic expertise into the public sphere, spearheading initiatives to improve sanitation, waste disposal, and urban infrastructure. This dissertation examines the Louisville Women’s City Club (LWCC) as a case study of municipal housekeeping, demonstrating how middle-class women used their traditional roles to influence systemic reform in Louisville, Kentucky. By bridging gender history, urban environmentalism, and Progressive Era activism, this study reveals how the LWCC shaped public policy …

“A True And Broad Sympathy:” Thomas Hughes, Medievalism, And Social Justice In The Nineteenth Century, Sarah E. Stapleton

Theses and Dissertations--History

Thomas Hughes, author of Tom Brown’s Schooldays (1857), used medievalism to help solve social problems of the Nineteenth Century. This contravenes the traditional view of medievalism, especially Anglo-Saxonism, since others have used it to justify the subjugation of people of lower social status, namely the poor in England, enslaved African Americans in the United States, and Indians under British rule.

While the use of medievalism is veiled in Hughes’ work, the subtext of Tom Brown’s Schooldays demonstrated Hughes’ Anglo-Saxonism. Tom Brown and the intertextual material surrounding his narrative exhibit the characteristics of Anglo-Saxonism through cultural primitivism, the concept of allodial, …

The Alchemy Of Jim Crow And Chinese Exclusion: A Study Of Chinese Mississippian Experience From Reconstruction To The Civil Rights Movement, 1870-1967, Sixu Liu

Theses and Dissertations--History

This dissertation examines the history of the Chinese community in Mississippi from the Reconstruction era to the late 1960s. Despite the modest size of their population, the experience of Chinese Mississippians helps us answer a number of key questions regarding two of America’s most impactful institutions, Chinese exclusion and Jim Crow, and their recipients. Why did Chinese Mississippians come to a state that was known for racial hatred and racial oppression? How should a people that was neither Black nor White situate themselves in a society dictated by a Black-White binary? How did Mississippi, a state that was often not …

Three Essays On The Impacts Of Pollution, Isaiah Chapman Bryant Sheth

Theses and Dissertations--Economics

My dissertation is broadly focused on using data to quantify the consequences of pol- lution and is organized into three chapters. Chapter one estimates the effect on infant health of drinking water contamination attributable to tropical cyclones. Chapter two examines the heterogeneous effects of a policy aimed at reducing air pollution based on pre-existing air quality conditions. Lastly, chapter three investigates how regula- tions aimed at shaping housing development to minimize climate risk impacted the housing market in Houston Texas. Each of these chapters considers different con- sequences of pollution, from direct health costs of pollution exposure to secondary effects …

Investigating Regulation And The Regulome Of The Nucleic Acid Binding Protein Spovg Within Borrelia Burgdorferi, Timothy C. Saylor

Theses and Dissertations--Medical Sciences

Prior studies indicated Borrelia burgdorferi SpoVG protein was regulated, SpoVG binds specifically to a number of nucleic acids, and SpoVG binds to the non-variable section of the major virulence factor vlsE. Although a direct transcriptional activator or inhibitor was not elucidated, it is shown that SpoVG is regulated based on cell culture density independent of the growth rate of B. burgdorferi, indicating that SpoVG regulation is outside the scope of the alternative sigma factor RpoS. Using a dCas9 CRISPRi construct to target SpoVG resulted in protein expression trending towards upregulation of the BosR-RpoS regulon, and a marked decrease …

Cellular And Behavioral Consequences Of Psychedelic Drug Action In The Claustrum, Tanner L. Anderson

Theses and Dissertations--Neuroscience

Psychedelics are rapidly garnering research attention for their ability to successfully treat a variety of psychiatric diseases after one or a handful of treatments in recent clinical research. Among the conditions treated is substance use disorder (SUD), which afflicted 48.5 million (16.7%) Americans aged 12 and older in 2023 (NSDUH). As clinical trial results continue to show lasting positive effects of psychedelic psychotherapy, there remains an enormous gap in knowledge regarding how these drugs cause lasting changes in the brain to achieve these therapeutic effects. It has been suggested that psychedelics must induce rapid and long-lasting neuronal plasticity in order …

Leveraging Clinical Standards To Improve The Translational Relevance Of Therapies For Experimental Spinal Cord Injury, Aaron L. Silverstein

Theses and Dissertations--Neuroscience

Efforts to improve treatment of spinal cord injury (SCI) often use animals to develop effective therapeutics, intending to improve the survival and the quality of life of persons with SCI. Over half of all SCIs in the United States occur at the cervical level and often cause locomotor deficits and life-threatening breathing dysfunction. Thus, my dissertation is focused on this important patient population.

After beginning with a description of translational research and surveying SCI from a clinical standpoint, I turned to describe experimental models of cervical SCI and more detailed neuroimmunological findings relevant to my work. Then, I conducted a …

Understanding The Impact Of The Medicaid Expansion On Hospital Length Of Stay And Emergency Department Use In Kentucky, Cameron Bushling

Theses and Dissertations--Epidemiology and Biostatistics

Three related analyses were performed to try to understand the immediate effects of Medicaid expansion on hospital systems in Kentucky. Medicaid expansion led to a large, sudden increase in the number of individuals eligible for various health care needs. This sudden increase in demand for health services lead to initial hypotheses regarding hospitals’ ability to handle this demand. The first analysis examined hospital average length of stay (LOS) using a linear mixed-effects model. Length of stay was modeled longitudinally between 2013 and 2015 to determine if significant changes in the slope of LOS could be detected after expansion (2014). Separate …

Changes In Cancer Diagnosis And Survival In The United States During The Covid-19 Pandemic, Justin T. Burus

Theses and Dissertations--Epidemiology and Biostatistics

The COVID-19 Pandemic led to global societal disruptions as political leaders and public health authorities attempted to control the spread of the newly discovered SARS- CoV-2 virus. While these measures were designed to lessen morbidity and mortality from a novel pathogen, their impact was also felt in many other, often unintended ways. The purpose of this dissertation is to use cancer surveillance research methods to examine the association between COVID-19 Pandemic-related disruptions and changes in the normal diagnosis and care of cancer in the United States.

The first two studies of this dissertation analyzed reductions in cancer diagnoses in the …

Ideals And Idealization: Responding To Rawls And His Critics, Clayton J. Houdeshell

Theses and Dissertations--Philosophy

In A Theory of Justice, John Rawls argues that any participant taking on the role as impartial spectator in his original position thought experiment would select “justice as fairness” as the most reasonable theory of justice to reorganize a basic structure’s system of institutions and public rules. In this dissertation it is my aim to outline seven criticisms of the Rawlsian account related to his method of ideal theory, the rationality and values of the impartial spectator, the instilment of a particular conception of the good and an aversion to non-liberal theories, and argue that each of them fail to …

Hannah Arendt As Hermeneutic Phenomenologist: Natality And The Miracle Of Philosophy, Andrew H. Marquis

Theses and Dissertations--Philosophy

I argue that Hannah Arendt practiced hermeneutic phenomenology in the canonical mode of her mentor, Martin Heidegger. Hermeneutic phenomenology is not a philosophical school defined by methods, results, or topics. It is a practice of transformative thinking by which we work through the burdens of who and how we have been towards the possibilities of who and how we could be. Heidegger, burdened by the scientism of his philosophical milieu, articulated this practice not by rejecting scientistic philosophies outright but by interpretively recovering their most promising tendencies.

Though seldom recognized as a hermeneutic phenomenologist, Arendt’s philosophical response to Nazism reveals …

Internalism, Externalism, And The Phenomenology Of Epistemic Justification, Steven Winterfeldt

Theses and Dissertations--Philosophy

This dissertation applies a phenomenological method of analysis to the dispute between analytic internalists and externalists regarding epistemic justification. Traditionally, the justification condition on knowledge has been interpreted as an internal condition, but the growing popularity of the externalist antithesis has placed internalism on the defensive. Ultimately, however, the dispute appears to have fallen into an impasse. I identify a set of four arguments or cases that, when taken together, prompt us to adopt a set of contradictory conclusions about the necessary and sufficient conditions for justified belief. Moreover, none of the analytic views of justification surveyed seem to be …

Harnessing Ethnicity For Effective Leadership: Reimagining Ethnic Politics As An Institutional Asset In Africa, Obaloluwa A. Aka

Theses and Dissertations--Political Science

Ethnic identity remains one of the most enduring forces shaping political behavior and leadership in Africa. Often viewed as a source of division, this study reframes ethnicity as an institutional asset capable of fostering accountability and enhancing leadership quality. Drawing on Afrobarometer Round 9 data from 35 African countries, the paper shows that ethnicity consistently predicts vote choice affirming its political salience. Rather than treating this as a democratic obstacle, the analysis demonstrates that when mediated through trusted traditional leaders, ethnic identity can strengthen satisfaction with democracy, trust in institutions, and perceptions of governance. Logistic regression models reveal that trust …

Towards A Sociological Theory Of Consent And Coercion In Sexual Violence Against Women, Lisa Kistler

Theses and Dissertations--Sociology

Recent data estimate that 26.8% of adult women in the U.S. have experienced rape in their lifetime. In this context, the phrase “consent to sex” is a prominent narrative countering sexual violence. Yet, there is no consensus on the meaning of consent, nor how the practice of consent is affected by coercion, resulting in a puzzle of consent. In response, the present project brings together existing research and theory to conceptualize consent and coercion in new ways. It asks, broadly, how do different forms of coercion complicate sexual consent and contribute to sexual violence against women today and answers this …

A Comprehensive Exploration Of Stress And Depressive Symptoms In Farm Populations, Julie C. Derringer

Theses and Dissertations--Nursing

High rates of depression and suicide continue to be a concern, despite four decades of growing research into the mental health of farmers. Most farmers have an awareness of a need for improved mental health, but a lack of knowledge persists. As agricultural production demands increase and the number of family farms decreases, the stress placed upon farmers to support the food chain is higher than ever. Understanding the association between farm demands and resources among farmers is key for the development and implementation of programs to decrease occupational stress and depressive symptoms to improve mental health outcomes across farming …

Anxiolytic Intervention: Modulation Of Cell Types Due To Nicotine Withdrawal, Taylor Elder

Theses and Dissertations--Pharmacy

Nicotine use disorder (NUD) remains a leading cause of preventable disease, yet the neurobiological mechanisms underlying nicotine withdrawal are incompletely understood. Emerging evidence implicates neuroimmune signaling and astrocytic regulation of glutamate in shaping the withdrawal-associated affective phenotype. This dissertation investigated these processes using multiple nicotine administration paradigms including osmotic minipump implant, cigarette smoke exposure, and nicotine vapor inhalation to model diverse routes of human nicotine intake.

Chapter 2 examines the effects of these three modes of administration on neuroinflammation and validation of nicotine delivery. Nicotine exposure was confirmed through receptor [³H]Epibatidine nAChR binding assay and serum cotinine measurements. …

Collision Avoidance Information System Utilizing Machine Learning Image Recognition, Michael W. Long

Theses and Dissertations--Mining Engineering

This thesis addresses significant safety challenges presented by powered haulage fatalities in underground mining by developing and evaluating a machine learning-driven Collision Avoidance Information System (CAIS). The research utilized a ZED 2i camera to capture both RGB and depth data for enhanced spatial awareness in visually limited underground environments. A specialized dataset of underground mining equipment was captured from limestone and zinc mines, annotated, and used to train a segmentation network. The CAIS was field-tested in diverse underground settings, achieving an accuracy of 82% in a limestone mine similar to the training data, but a lower accuracy of 45% in …

Temporal Machine Learning For Predicting Accidents And Violations In The Mining Industry, Nathan T. Kelley

Theses and Dissertations--Mining Engineering

This thesis examines the predictive capability of a temporal machine learning model for forecasting future accidents and violations at individual mines, based on historical data. Mine accidents were categorized by accident classification and violations were categorized by the Part Section. The primary datasets utilized were the mine safety and health administration’s (MSHA’s) Accident Injuries and Violations datasets. The available datasets were cleaned and organized by mine type and commodity, then divided into separate subsets for training, validating, and testing. Different models, cutoff metrics, learning rates, number of hidden layers, data processing methods, data processing divisions, number of points observed …

Analysis Of Ptfe Radial Lip Seals For Wheel Bearing Applications, Madison Vogt

Theses and Dissertations--Mechanical and Aerospace Engineering

A numerical analysis was conducted to investigate the viscoelastic effects of nonlinear materials on the sealing zone and contact pressure distribution of radial lip seals in a conventional geometric topology. The use of nonlinear materials in radial lip seal applications is desirable to improve operation and reliability of rotating machinery due to their high operating temperatures, chemical compatibility, and low friction coefficients. Examples include, but are not limited to, seals within industrial air compressors, turbine engines, aircraft landing systems, chemical processing equipment, and Freon pumps. This work focuses on analyzing the nonlinear viscoelastic response of pure Polytetrafluoroethylene (PTFE) and PTFE …

Simplified Molecular Diagnostics Methods For Environmental Testing Of Pathogens And Other Applications, Mohammad Dehghan Banadaki

Theses and Dissertations--Mechanical and Aerospace Engineering

Environmental Surveillance (ES) has emerged as a powerful tool to monitor the emergence and persistence of a pathogen within a facility or community using wastewater/water analysis. Over the past four years, implementation of ES has experienced an explosive acceleration, driven by efforts to monitor the spread of SARS-CoV-2, which has made ES a routinely used public health tool in many locations. We can now use ES to measure the emergence/presence/abundance of different viruses (e.g., SARS-CoV-2, influenza, mpox), bacteria (e.g., E. coli, V. cholerae, antibiotic-resistant strains), fungi (e.g., C. auris), and other biological markers indicative of infectious diseases. However, its broad …

In Situ Bourbon Barrel Measurements Of Alcohol By Volume And Liquid Depth Using Borosilicate Glass Probes And Near Infrared Absorption Spectroscopy, Trent T. Reed

Theses and Dissertations--Mechanical and Aerospace Engineering

In pursuit of measuring different variables present in bourbon barrels, absorption spectroscopy was utilized to ensure that different ethanol and water concentrations can be differentiated using a broadband light source and near infrared spectrometer in a simple cuvette-based testing setup. The intensity and absorption plots gathered of different ethanol and water mixtures were then analyzed using proper orthogonal decomposition (POD) to break down the data into modes which represent specific variables of interest, specifically ethanol concentration or alcohol by volume (ABV). The modes were then utilized to find mode constants to represent the data taken from cuvette samples which were …

Acoustic Characterization Of A Quadcopter Using A Test Stand, Jared Schmal

Theses and Dissertations--Mechanical and Aerospace Engineering

Unmanned Aerial Vehicles (UAVs) with multirotor propulsion and control, commonly called drones or multicopters, generate a complex acoustic field that is not entirely understood. Many components and their interactions contribute to the overall noise level and behavior of the acoustic field. However, performing acoustic measurements on a multicopter in a confined space, such as a small anechoic chamber, can be an extremely difficult and time-consuming process. A test stand was developed to allow for rapid and safe acoustic measurements in a controlled environment. The design, development, and initial measurements are discussed. The performance and acoustic response are assessed to examine …
