A Frayed Edge: A Qualitative And Poetic Inquiry Analysis Of White Antiracist Protest In 2020, Emily Katt

Electronic Theses and Dissertations

This multiphasic study explored the narratives of five first-time Black Lives Matter protesters demonstrating during the historic confluence of conflicts in 2020 America. After positioning the liminal 2020 circumstances within an antiracist research lens, the author analyzed, first through grounded theory and then secondarily through poetic inquiry, how these five participants described their protest experiences. The grounded theory phase yielded an overarching theory that first-time protestors experienced a dual process of unsuturing and of calling-out, with three subthemes categorized within each of these two processes. The author moved into analysis with the poetic inquiry phase, crafting poems guided by six …

Voltage-Gated Potassium Channel Dependent Mechanisms Of Cardiovascular Adaptation To Chronic Exercise., Sean Raph

Electronic Theses and Dissertations

Exercise increases cardiac workload, escalating the demand for oxygen. The myocardial vasculature responds to the greater demand for oxygen by increasing blood flow to match the needs of the heart during augmented work. Increasing blood flow requires the coronary arteries dilate (a.k.a. vasodilation); this is mediated predominantly by vascular smooth muscle cell relaxation. Vasodilation is driven through inhibition of calcium influx into vascular smooth muscle cells. The prevention of calcium influx is largely mediated by efflux of potassium via potassium channels causing membrane hyperpolarization, which in turn closes voltage-dependent (or gated) calcium channels (VDCC). Changes in vascular smooth muscle cell …

Power In Portrayal: An Exploration Of The Evolving Cold War Relationship Between Germany And America Through Film, Kaleb Wentz

Electronic Theses and Dissertations

The end of the Second World War brought many questions to the United States. One of the greatest among these was what to do with defeated Germany. Many clamored for the dissolution of the former Nazi State and the shameful humbling of its people while others recognized the value of a revitalized Germany as an ally against the looming threat of an emboldened and empowered postwar Soviet Union. Though retribution held sway immediately following the war, the Cold War consensus of an alliance with West Germany and a reimagining of the German people as victims rather than perpetrators won out …

Domestic Violence Against Men: Their Report Decision Making Process, Ngozi Aleke

Electronic Theses and Dissertations

Little or nothing is really known about a man’s victimization in a domestic violence situation. Generally domestic violence is viewed from the lens of a women with the typical idea that women are the victim while men, the perpetrators of violence. Overtime, this societal perception is beginning to subside as researchers have proven that men are also victims of domestic violence (Straus, Gelles, & Steinmetz,1980). Despite this revelation, not much is known about male victimization as most men prefer not to report their victimization. This study seeks to examine the reasons for not reporting victimization and the effect of this …

Investigating The Pi3k/Akt/Atm Pathway, Telomeric Dna Damage, T Cell Death, And Crispr/Cas9-Mediated Gene Editing During Acute And Chronic Hiv Infection, Sushant Khanal

Electronic Theses and Dissertations

Human Immunodeficiency Virus (HIV) infection initiates major metabolic and cell- survival complications. Anti-retroviral therapy (ART) is the current approach to suppress active HIV replication to a level of undetected viral load, but it is not a curative approach. Newer and sophisticated gene editing technologies could indeed be a potent antiviral therapy to achieve a clinical sterilization/cure of HIV infection. Chronic HIV patients, even under a successful ART regimen, exhibit a low-grade inflammation, immune senescence, premature aging, telomeric DNA attrition, T cell apoptosis, and cellular homeostasis. In this dissertation, we investigated CD4 T cell homeostasis, degree of T cell apoptosis, an …

Nitrogen-Doped And Phosphorus-Doped Epoxy-Sealed Carbon Fiber Ultramicroelectrodes As Electrochemical Sensors For Detection Of Hydrogen Peroxide, Emmanuel Peprah-Yamoah

Electronic Theses and Dissertations

Ultramicroelectrodes (UMEs) are useful as probes for evaluating electroactive species in confined spaces (e.g., inside living cells) and for measuring fast electrochemical reactions. However, UME applications often require modification of the electrode surface to improve selectivity and sensitivity towards target analytes. Previous research in our group demonstrated that a simple soft nitriding method introduces surface nitrogen (N)-containing groups on carbon fiber (CF), leading to improved electroreduction of hydrogen peroxide (H₂O₂) on CF-UMEs. However, sensitivity for H₂O₂ detection using N-CF-UMEs was low compared to that for other modified UMEs. As an alternative to N-CF-UMEs, …

How An Abusive Supervision Climate Impacts Business-To-Business (B2b) Sales Performance, And The Roles Of Leader–Members Interdependence And Team Psychological Safety, Matthew J. Daniel

Electronic Theses and Dissertations

Sales supervisors can tremendously influence the sales teams they manage, and their behaviors can influence a team’s engagement and sales performance. Because of the supervisor’s influential role, their behavior, positive or negative, can ripple throughout the organization. As a result, a supervisor who role models abusive behavior within their organization also promotes a climate of abuse and incivility that can contribute to a toxic workplace. Abusive supervision (AS) is a significant problem in many business-to-business (B2B) sales organizations that negatively impacts the financial welfare and subjective well-being of organizations and their employees. This quantitative correlational study aimed to examine how …

This project explores cities as urban ecologies of communication in which crises emerge and are given significance within the dialogic relations cultivated among public actors attempting to make a living, together, within the shared historical-cultural contexts of everyday life. To describe cities as urban ecologies of communication is to describe them in terms of urban communication and its interdisciplinary foundations in the study of rhetoric, philosophy, planning, policy, architecture, sociology, geography, and media. The first chapter introduces the challenges of urban risk and crisis management within the complex ecologies of communication constituted by cities and reviews how ‘risk’ and ‘crisis’ …

Novel Signal Sequences And Fusion Partners For Paratransgenesis In Asaia, Christina Grogan

Electronic Theses and Dissertations

Mosquitoes transmit many pathogens that cause human disease. One such disease, malaria, is caused by parasites in the genus Plasmodium, infecting over 200 million people and killing over 600,000 per year. Current strategies to control vector-transmitted diseases are increasingly undermined by mosquito and pathogen resistance. Research has turned to additional and novel methods of control, such as altering the microbiota of the vectors. In this method, called paratransgenesis, symbiotic bacteria are genetically modified to affect the mosquito’s phenotype by engineering them to deliver antiplasmodial molecules into the midgut to kill parasites. These molecules must be released by the …

The Effects Of Digital Game-Based Instruction On Knowledge Acquisition And Retention Of Genetics Content, Brinley Kantorski

Electronic Theses and Dissertations

Digital educational games have been a part of the educational landscape since the early 1970s. Since then, there has been a proliferation in the quantity, format, type, and quality of digital educational games available to classroom teachers. Despite this, the body of literature surrounding the effectiveness of these digital educational games remains highly fragmented and lacks unifying themes. While some literature exists to support the use of digital educational games in immediate knowledge acquisition, little research has been done on how digital educational games impact the retention of knowledge in the long term. As such, this study examines how the …

Identification And Characterization Of Genetic Elements That Regulate A C-Di-Gmp Mediated Multicellular Trait In Pseudomonas Fluorescens, Collin Kessler

Electronic Theses and Dissertations

Microbial communities contain densely packed cells where competition for space and resources are fierce. These communities are generally referred to as biofilms and provide advantages to individual cells against immunological and antimicrobial intervention, dehydration, and predation. High intracellular pools of cyclic diguanylate monophosphate (c-di-GMP) cause cells to aggregate during biofilm formation through the production of diverse extracellular polymers. Genes that encode c-di-GMP catalytic enzymes are commonly mutated during chronic infections where opportunists display enhanced resistance to phagocytosis and antibiotics. Our lab uses an emergent multicellular trait in the model organism Pseudomonas fluorescens Pf0-1 to study the emergence of c-di-GMP mutations …

The term empathic response refers to as attending to the emotional and mental state of another person in a way that is attuned with the feelings and meanings of the individual’s experience. There are few studies that have assessed the merits of telephonic counseling, and even fewer that have examined counselors’ empathic response to clients through this medium.

To uncover the lived experience of the target population, the participants of the study were purposefully selected …

Rendering Documentary Portraiture: An Interrogation Of Archival Discourse Through A Critical Exploration Of Nineteenth Century Stage Actress Charlotte Cushman’S Material Memory, Skyler Sunday

Electronic Theses and Dissertations

Visual depictions of nineteenth century stage actress Charlotte Cushman, such as photographs, engravings, and painted portraits assist researchers in re-envisioning her both as an actress and as a person, but what do her remaining archival possessions further reveal to researchers about her memory? How do different objects operate as portraits that allow the researcher to tap into and remember specific moments and memory? How does the effort to preserve memory take different forms? This project argues that, when viewing the archive through its stored objects, our collective notion of portraiture can be expanded and used to interrogate existing methods of …

Labeling Melanoma Cells With Black Microspheres For Improved Sensitivity In Detection Via Photoacoustic Flow Cytometry, Tori Kocsis

Electronic Theses and Dissertations

Melanoma is an aggressive form of skin cancer known for developing into metastatic disease. Current clinical diagnostics, including medical imaging and tissue biopsy, provide a poor prognosis since the cancer is in the late stages of disease progression. In recent years, photoacoustic flow cytometry has allowed for the detection of circulating melanoma cells within patient blood samples in vitro. Although this method exploits the naturally-produced melanin within the cells, it has only successfully detected highly-pigmented melanoma cell lines. Since various forms of melanoma exist, each with varying melanin concentrations, this research aims to provide a novel method for detecting lightly-pigmented …
