Small-Scale Variability In Warm Season, Precipitation Around An Urban Area: A Case Study Of Louisville-Jefferson County, Ky., Isaiah I. Kingsberry May 2022

Small-Scale Variability In Warm Season, Precipitation Around An Urban Area: A Case Study Of Louisville-Jefferson County, Ky., Isaiah I. Kingsberry

Electronic Theses and Dissertations

Numerous studies have detected anomalous precipitation patterns occurring up to 50 km downwind of major cities, providing major evidence that cities inadvertently modify precipitation and atmospheric circulations. Louisville is one such major city with a growing body of evidence of inadvertent precipitation modification. Despite these efforts, the physical mechanisms driving small-scale and unintentional changes in urban precipitation are little understood, being rooted largely in theory rather than in physical observations. This study seeks to build upon previous research by analyzing ground-based precipitation observations recorded by a high-density gauge network located within approximately 40 km of Louisville’s urban center. The results …


Meat The Future., Xin Chen May 2022

Meat The Future., Xin Chen

Electronic Theses and Dissertations

This research focuses on the subtle relationship between human life, the environment, and other animals that we live among every day. Under the mainstream social background of capitalism and a commodity economy, animals are the victims of constant consumption and exploitation. However, meat is a basic substance for human nourishment, especially in certain cultures. As a result, meat becomes an important part of the commodity economy in capitalist societies, wherein the supply must be filled to accommodate society’s demand. This research formed an exhibition using glass and ceramic artwork using a playfully satirical tone to offer a crucial alternative: how …


Beyond A Divide: Reconceptualizing Digital Capital And Links To Academic Proficiency., Ryan Price May 2022

Beyond A Divide: Reconceptualizing Digital Capital And Links To Academic Proficiency., Ryan Price

Electronic Theses and Dissertations

In the digital inequality literature, the popular notion of a “digital divide” is frequently used to discuss digital inequality; however, this framework is overly simplistic and cannot adequately capture the complex nature of digital inequality. Some scholars have adopted a framework of digital capital to attempt a multidimensional approach to this social problem, but the literature lacks consistent empirical measurements. Using U.S. data from the Programme for International Student Assessment (PISA) 2018 Survey, I seek to propose, and validate, internally consistent principal components of digital capital among 15-year-old high school students in the US. I conduct a Principal Component Analysis …


On The Subject Of Loneliness., Isaac Raymond Smith May 2022

On The Subject Of Loneliness., Isaac Raymond Smith

Electronic Theses and Dissertations

Loneliness has been experienced since ancient times, but all were made acutely aware of the need for social interaction during the long periods of lockdown during 2020 and 2021. on the subject of loneliness draws inspiration from a variety of texts which examine the complex effects of loneliness from emotional, scientific, and spiritual viewpoints. Redactions and rearrangements of these texts form a new narrative which does not always follow a linear form or work toward a clear goal. The speaker’s internal dialogue formed from the disparate texts reflects the impact of loneliness on the music itself; only in retrospect do …

A Mesonet-Based Analysis Of Severe Convective Winds In West Texas., Quint Long May 2022

A Mesonet-Based Analysis Of Severe Convective Winds In West Texas., Quint Long

Electronic Theses and Dissertations

Multiple studies have investigated the occurrence of severe convective-related winds and have increased our understanding of the forces driving severe winds and their spatial and temporal patterns. Data for these studies have come from airport stations maintained by the National Weather Service. Their standardization across the United States makes them ideal for research, but they are limited in their distribution. This study aims to create a similar climatology of severe surface level winds using a mesoscale network (“mesonet”). Like their ASOS (Automated Surface Observing System) and AWOS (Automated Weather Observing System) counterparts, these stations are standardized and well maintained. This …

This study examines the impact of experiences of colorism on the crime trajectory of African Americans. It is qualitative in nature and utilizes semi-structured interviews with incarcerated African American people. As previous research has shown the painful impact of colorism on its victims, this study ultimately seeks to unearth if that pain translates into crime commission and trajectory. The primary purpose of this research is to contribute to the existing body of research that seeks to support “colorism healing” in the African American community. If this indicates that colorism contributes to crime trajectory, such an outcome would have practical implications: …


The Effects Of Previous Traumatic Experiences On Learning Outcomes: Perceptions Of Black Men Who Are Attending Community College, Willie Thomas May 2022

The Effects Of Previous Traumatic Experiences On Learning Outcomes: Perceptions Of Black Men Who Are Attending Community College, Willie Thomas

Electronic Theses and Dissertations

Academic underachievement among Black students, particularly Black male students, is a troubling trend that has long attracted scholarly attention. The prevailing consensus is that the shortcomings of some Black male students in academic achievement may be attributable to traumatic experiences arising from environments of violent, inner-city poverty that disproportionately affect Black men. Traumatic experiences have been shown to negatively affect Black men’s self-perception, emotions, self-image, and social and cognitive skills, with consequences in the form of measured shortfalls in retention and graduation rates. My qualitative, phenomenological study sought to explore how previous traumatic experiences of Black men affected their academic …

Expression And Functional Characterization Of Avocado Dgat1 And Pdat1 In Arabidopsis And Camelina, Josphat Kiunga May 2022

Expression And Functional Characterization Of Avocado Dgat1 And Pdat1 In Arabidopsis And Camelina, Josphat Kiunga

Electronic Theses and Dissertations

The study is aimed to determine the role of avocado DGAT1 and PDAT1 in seed oil synthesis. Triacylglycerol (TAG) has a nutritional and industrial value and is essential for plant growth. DGAT1 and PDAT1 catalyze the final step of TAG Assembly. We hypothesized that both PaPDAT1 and PaDGAT1, although predominantly expressed in non-seed tissues, could contribute to oil accumulation in seeds. Agrobacterium transformants with PaPDAT1 and PaDGAT1 cloned in pCAMBIA were generated to test this. Subsequently, the Agrobacterium-mediated transformation of Arabidopsis mutant lines and camelina was carried out by floral dipping. The T1 camelina seeds …


Combating Frailty: Application Of A Modified Skeletal Frailty Index In Modern Military And Civilian Populations., Emily M. Frazier May 2022

Combating Frailty: Application Of A Modified Skeletal Frailty Index In Modern Military And Civilian Populations., Emily M. Frazier

Electronic Theses and Dissertations

Conceptualizing, quantifying, and evaluating frailty in human skeletal remains is critical to understanding and interpreting physiological health and stress among past populations. While many researchers focus on frailty in bioarchaeological samples, developing models for mortality risk and individual- and population-specific indices of stress, no current methods directly address frailty in forensic contexts. This study considers the applicability of a modified index for assessing frailty in forensic anthropology by comparing distributions of 8 biomarkers of stress (linear enamel hypoplasia; periodontal disease; caries; osteoarthritis; intervertebral disc disease; rotator cuff disorder; antemortem fracture; and surgical procedure) using the original skeletal frailty index (SFI) …

Public Health Contagion Of White Supremacy: Examining The Pipeline Of Attitudes About Racism And Racial History Education Among High School Students., Trinidad Jackson May 2022

Public Health Contagion Of White Supremacy: Examining The Pipeline Of Attitudes About Racism And Racial History Education Among High School Students., Trinidad Jackson

Electronic Theses and Dissertations

We are living in compounded states of upheaval. Violence and exemption from it across socioecological levels have shaped how humans survive, thrive, and die. While different violence typologies exist, the U.S., prioritizes interpersonal violence as its primary target of intervention, often through structural means that foster and reinforce interpersonal violence. The omission of structural and cultural agents and outcomes of violence allows perpetrators to infiltrate and reproduce savage, dehumanizing ideologies in perpetuity. Instead of sustaining societal pillars that oppress and destroy, we must fertilize public health research, practice, and sociopolitical activism with pillars that both inform and activate liberatory consciousness …


Genomic Tools And Models For Investigating The Role Of Germline Diversity In Mouse Antibody Repertoire Development., Justin T. Kos May 2022

Genomic Tools And Models For Investigating The Role Of Germline Diversity In Mouse Antibody Repertoire Development., Justin T. Kos

Electronic Theses and Dissertations

Given the diversity and complexity within immunoglobulin (IG) loci, effective mouse models first require characterization of intra-strain differences and construction of high-quality reference assemblies for IG loci in several representative strains. To understand light chain germline diversity across biomedically significant mouse strains, we profiled the expressed IGK and IGL repertoires of 18 commonly used laboratory mouse strains using AIRR-seq. Across strains, we observed germline IGKV sequences shared by three different IGK haplotypes and a more conserved IGLV germline repertoire among common laboratory strains. Pacific Biosciences (PacBio) Single-Molecule Real-Time (SMRT) sequencing was used to sequence and assemble bacterial artificial chromosomes (BAC) …


Role Of Galactose, Thiazolidinediones, And Neet Proteins In Mitochondrial Physiology And Therapeutic Development., Robert Anthony Skolik May 2022

Role Of Galactose, Thiazolidinediones, And Neet Proteins In Mitochondrial Physiology And Therapeutic Development., Robert Anthony Skolik

Electronic Theses and Dissertations

This dissertation explores the relationship between mitochondrial physiology and development of therapeutics. Mitochondrial dysfunction is associated with both acute and chronic forms of pathophysiology. This work aims to address development efforts at the cell culture and drug-target levels with respect to mitochondria. At the cell culture level, I characterize an approach that has been shown to improve the physiological dependency on mitochondria in tumor-derived cells. I demonstrate that prolonged replacement of glucose with galactose in culture medium induces a global metabolic shift in hepatocellular carcinoma (HepG2) cells to closer reflect a primary hepatocyte phenotype (Chapter 2). I characterize this shift …

(De)Legitimizing Genres: Rhetoric And Tactical Institutional Critique., Walker Smith May 2022

(De)Legitimizing Genres: Rhetoric And Tactical Institutional Critique., Walker Smith

Electronic Theses and Dissertations

This dissertation forwards a rhetorical theory of institutions that centers their genre-based communications, redefines institutions in relation to organizations, and contributes to the field’s understanding of how communities collaboratively rewrite entrenched institutionalized practices from the outside, thus reducing the harm that institutions can enact. Using evangelical church policies on marriage as a case study, I answer the following questions: How do historically sedimented institutions, their genres, and their practices rhetorically impose, legitimize, and regulate certain patterns of social life? How does an evangelical Christian church manage to govern the gendered and sexual lives of their members and maintain their power …


The Water We Were Swimming In: Transgender And Gender Nonconforming Students' Lived Experiences In Engineering., Natalie Saroff Oliner May 2022

The Water We Were Swimming In: Transgender And Gender Nonconforming Students' Lived Experiences In Engineering., Natalie Saroff Oliner

Electronic Theses and Dissertations

Few studies address the lived experiences of transgender and gender nonconforming (TGNC) students in engineering. Grounded in critical trans politics (Spade, 2015), this dissertation contributes to the literature on TGNC students in engineering by examining their experiences negotiating their identities while navigating interrelated systems of oppression in a field dominated by White, heterosexual, cisgender men. Using a critical constructivism framework, I conducted a narrative inquiry to explore the lived experiences of five TGNC students in engineering programs. Participants experienced TGNC oppression at their universities, built LGBTQ+ and TGNC communities, and described more welcoming climates in non-engineering contexts compared to engineering. …

Authentically (Un)Real Assessing Vh!'S Basketball Wives And Its Violent & Colorist Portrayals Of Black Women., Wilma Denae Powell

Electronic Theses and Dissertations

Does reality television serve as solely a form of entertainment, or could reality television also be maintaining hegemonic beliefs and reinforcing biased views of Black women? Since 2010, Vh1’s Basketball Wives has given audiences the opportunities to entertain themselves by watching women who are/were married to, dating, or are the mothers of children fathered by professional basketball players. Despite the show’s name, few members of the cast are currently married and audiences only get mere glimpses of the cast in motherly or marital interactions. So, what does Basketball Wives offer audiences who tune in to watch Black women for entertainment? …

The Glass Coffin: Gothic Adaptations And The Formation Of Sexual Subjectivity., Colton T. Wilson May 2022

The Glass Coffin: Gothic Adaptations And The Formation Of Sexual Subjectivity., Colton T. Wilson

Electronic Theses and Dissertations

It is now an almost foregone conclusion that classic depictions of vampirism resonate with contemporary queer audiences. A sympathetic response to the monster’s persecution is often the key factor in these arguments, yet little attention is paid to the textual details that prompt such a process of identification. This study posits that the iconography used to establish a connection between monstrosity and non-normative sexuality has its origins in Victorian Gothic fiction, whose descriptions of vampirism were assimilated into the discourse of the fin-de-siècle medical field known as sexology. Theories that defined homosexuality as an illness with physical and psychological symptoms …


Cannabinoids And Retinal Fibrotic Disorders., Lucy June Sloan May 2022

Cannabinoids And Retinal Fibrotic Disorders., Lucy June Sloan

Electronic Theses and Dissertations

Retinal fibrosis is detrimental to vision. Retinal pigment epithelial (RPE) cells contribute to several retinal fibrotic diseases. Upon exposure to TGF-β, a key fibrotic cytokine, RPE cells trans-differentiate to myofibroblasts marked by the integration of α-SMA fibers into F-actin stress fibers, which confer strong contractility. Myofibroblasts produce and contract the collagen-rich fibrotic scar and disrupt retinal architecture. In this study, we investigated the in vitro effects of the putative endocannabinoid compound N-oleoyl dopamine (OLDA) on TGF-β2 induced porcine RPE cell contraction and α-SMA expression. Using an in vitro collagen matrix contraction assay, we found that OLDA inhibited TGF-β2 induced contraction …
