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? …

Covid-19’S Effects On Mortality Salience, Death Anxiety, And Worldview Defense, Sahvannah K. Shavers

Electronic Theses and Dissertations

Since late-2019, the world has been trying to overcome an invisible killer: COVID-19. With near constant reminders of the virus the knowledge that a tiny viral particle has potential to harm or even kill has become overwhelming for many. Terror Management Theory (TMT) suggests that when individuals are reminded of their own death people take part in culturally appropriate activities and defend their own culture as ways to alleviate this increased death anxiety. The current study aims to identify whether 1) reminders of COVID-19 prime death thoughts, 2) reminders of COVID-19 increase death anxiety, and 3) increased death anxiety from …


Aggregatibacter Actinomycetemcomitans Exploits And Modulates The Immune Response By Human Neutrophils For Survival In The Anaerobic Environment., Hazel Ozuna May 2022

Aggregatibacter Actinomycetemcomitans Exploits And Modulates The Immune Response By Human Neutrophils For Survival In The Anaerobic Environment., Hazel Ozuna

Electronic Theses and Dissertations

Aggregatibacter actinomycetemcomitans (Aa) is a Gram-negative facultative anaerobe and an opportunistic oral pathogen, strongly associated with localized periodontitis and other inflammatory diseases. Periodontitis is a chronic inflammation of the periodontium resulting from the inflammatory response of the host towards the dysbiotic microbial community present at the gingival crevice. The host immune response creates a hostile environment for microorganisms; therefore, it is important for Aa to be able to regulate the necessary genes to survive and thrive in such an environment. Aaexpresses several virulence factors such as a cytolethal distending toxin (Cdt), lipopolysaccharide (LPS) and leukotoxin A (LtxA), …


Re-Localizing Writing Assessment: Sites Of Knowledge Mobilization., Charlotte Asmuth May 2022

Re-Localizing Writing Assessment: Sites Of Knowledge Mobilization., Charlotte Asmuth

Electronic Theses and Dissertations

For decades, writing assessment theorists have subscribed to the principle of localism––the belief that assessments should be designed with local contexts in mind and administered by local actors. Although this belief has ensured the validity of assessments in writing programs, it has also led to a tendency to treat assessment as a stable practice that is bound to a particular location, thus ignoring what happens when assessment knowledge and methods developed in one location travel to another distant location (as they do for campus assessment initiatives). To that end, this project traces how assessment knowledge is transformed as it travels …


Utilizing Shockwave Theory And Deep Learning To Estimate Intersection Traffic Flow And Queue Length Based On Connected Vehicle Data., Abdulmaged Algomaiah May 2022

Utilizing Shockwave Theory And Deep Learning To Estimate Intersection Traffic Flow And Queue Length Based On Connected Vehicle Data., Abdulmaged Algomaiah

Electronic Theses and Dissertations

The development of Connected Vehicles (CV) facilitates the use of trajectory data to estimate queue length and traffic volume at signalized intersections. The previously proposed models involved additional information that may require conducting different types of data collection. Also, most models need higher market penetration rate or more than a vehicle per cycle to provide adequate estimation. This is mainly because a significant number of the estimation models utilized only queued vehicles. However, the state of motion in non-queued vehicles, particularly slowed-down vehicles, provides much information about the traffic characteristics. There is a lack of exploiting the information from slowed-down …

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 …


Kurt Vonnegut, Modernity, And The Self: A Guide To The Good Life., Josh Simpson May 2022

Kurt Vonnegut, Modernity, And The Self: A Guide To The Good Life., Josh Simpson

Electronic Theses and Dissertations

What are people for? This is a question Kurt Vonnegut raises in his first novel, 1952’s Player Piano. Over five decades later, when he concludes a career with 2005’s A Man Without a Country, he is still asking, “What is life all about?” (66). These are the central questions for Vonnegut, and his novels, short stories, essays, interviews, correspondence, and commencement addresses offer a singular, life-long attempt at an answer. In this dissertation I offer a reading of Vonnegut not just as a writer concerned with philosophical questions, but rather, on a deeper, more personal level, as a …


Hiv And The African American Church: Millennial Faith Leader's Perspectives., Kelsey Leann Burton May 2022

Hiv And The African American Church: Millennial Faith Leader's Perspectives., Kelsey Leann Burton

Electronic Theses and Dissertations

African Americans are disproportionately impacted by HIV compared to other racial groups. Stigma surrounding HIV has created challenges for effective HIV prevention and stigma reduction programs. The African American church has been criticized for its slow and stigmatizing response to the HIV epidemic. Despite this, African American faith leaders play significant roles in guiding the perspective of the community. Numerous studies examine African American pastors’, faith leaders’, and ministers’ perspective about HIV and other HIV-related topics. However, there is no research that specifically examines young African American pastors’ perspectives of addressing HIV, stigma, and prevention. The purpose of this dissertation …

Etracellular Vesicles From Lactobacillus Rhamnosus Gg Protect Against Alcohol-Induced Liver Injury Through Suppression Of Intestinal Mir 194 And Subsequent Activation Of Fxr In Mice., Mengwei Jiang

Electronic Theses and Dissertations

Numerous studies have reported the efficacy of probiotics for alcohol-associated liver disease (ALD). These studies indicate a strong interest among the scientific and medical communities in identifying alternative or adjunctive approaches for ALD, for which there is no effective or widely accepted therapeutic option. However, in-depth molecular knowledge on how probiotics render their effects is lacking. Patients with ALD often have increased hepatic bile acids (BAs), which can be toxic and are an important causative factor in liver injury and hepatocyte death. BAs are released into the intestines and serve not only as a “detergent” to promote fat absorption, but …


Definitions And Depictions Of Rhetorical Practice In Medieval English Fürstenspiegel., Joseph Ethan Blaine Sharp May 2022

Definitions And Depictions Of Rhetorical Practice In Medieval English Fürstenspiegel., Joseph Ethan Blaine Sharp

Electronic Theses and Dissertations

This dissertation examines how medieval authors defined rhetoric and depicted rhetorical practice in medieval English Fürstenspiegel. It begins by analyzing how the field of medieval rhetorical historiography has overlooked the Fürstenspiegel as a rhetorical genre due to its overt reliance on meta-rhetorical handbook genres as the objects of its analysis. This dissertation challenges traditional narratives that positions medieval rhetoric as a primarily academic discipline divorced from political practice by engaging in horizontal reading practices that examine the broader culture of medieval rhetorical practice alongside the definitions of rhetoric found in medieval English Fürstenspiegel. In so doing, this dissertation …

“I Think It's Male Privilege”: A Qualitative Study Of Personal, Behavioral, And Socio-Environmental Factors Influencing High Risk Sexual Behavior And Hiv Transmission Among Heterosexual Adult Males In Ghana., Nana Ama Aya Erzuah Bullock

Electronic Theses and Dissertations

There are roughly 340,000 adults and children living with HIV. Despite the progress in the global response and the lowing of infections, HIV rates in Ghana remain stable. Cultural and societal norms that exist at a given time and place influence masculine socialization and behavior. These norms promote heterosexual men’s engagement in high-risk sexual behaviors which result in HIV infections. Factors such as HIV knowledge, risk perception, male condom use, HIV testing, and counseling which minimize the risk of HIV, are also influenced by these norms. Men have been identified as assets and advocates for behavior change and social responsibility …

(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 Experience Of Scanxiety In Survivors Of Pancreatic Cancer: A Phenomenological Study., Susan Winebrenner May 2022

The Experience Of Scanxiety In Survivors Of Pancreatic Cancer: A Phenomenological Study., Susan Winebrenner

Electronic Theses and Dissertations

Surveillance scans can signify a crisis point in a cancer patient’s life, provoking fear and anxiety that negatively impact quality of life. Scan-related anxiety or scanxiety has been briefly discussed in the literature among lung cancer and lymphoma populations, but relatively few investigations have studied the psychological impact of routine surveillance scans during cancer survivorship. The purpose of this study was to illuminate the lived experience of scanxiety in survivors of pancreatic cancer who have undergone curative surgical resection. Hermeneutic phenomenology as applied by Heidegger provided the philosophical underpinnings for this study and van Manen’s methodological approach was used to …

In hopes to offset this degradation, habitat restoration attempts to restore ecosystem function to an improved state resembling intact, remnant values. This is a difficult, but important, undertaking with factors to consider at multiple spatial and temporal scales. The restoration and conservation of pollinator communities has garnered heightened attention because of the valuable ecosystem services they provide. This dissertation investigates the local and landscape level factors of grassland restorations that influence plant-pollinator communities. I used a …


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 …

Critical Thinking Or Critical Creativity: Applying De Bono's Six Thinking Hats To Speech-Language Pathology Education And Practice., Samantha Hahn

Electronic Theses and Dissertations

Decision-making is a fundamental skill that health care professionals use daily which involves the interaction of many cognitive systems. Critical and lateral thinking are two approaches to decision-making often cited in literature. Critical thinking emphasizes reasoning and systematic analyzation, while lateral thinking encompasses imagination and creativity. Speech-language pathology (SLP) is a prime example of a profession that amalgamates creative processes with organized methodologies. Edward de Bono described six styles of lateral thinking – each style is equated to a colored “hat”. This study sought to determine if an association exists between a given SLP student’s level of clinical experience and …

This exhibition and document explore spatial rhetoric during the pandemic, utilizing materiality and relational aesthetics to reflect on the different ways in which the public and private are made distinct from one another. In doing so, Lewis addresses new cultural navigations of shared spaces, both digital and corporeal, public and private. In addition, the artist also examines the faulty social and institutional systems that the pandemic brought to light, such as socioeconomic dynamics and voter suppression, while utilizing Kenneth Burke’s concept of the terministic screen. Games are a central theme throughout the exhibition, as they are often coded as “home” …


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 …
