Transmission And The Evolution Of Diseases Caused By Chlamydia Trachomatis, Sars-Cov-2, And Plasmodium Species., Nathan Steffens

Electronic Theses and Dissertations

Principles of natural selection have proven valuable for explaining why pathogens cause the diseases that they do. In theory, the evolved level of host exploitation should reflect how dependent a pathogen is on host health for transmission. This dependency is shaped by transmission mode and transmission opportunity, which should therefore be predictors of disease manifestations. In this dissertation, I apply these principles to investigations of depression in Chlamydia trachomatis and virulence of SARS-COV-2 and Plasmodium species. This dissertation has five chapters. In chapter I, I describe the theoretical foundation of my dissertation research. I also briefly introduce each study system. …

Beyond the van der Waals-VH which possess of van der Waals (vdW) interaction, there are other types of heterostructures made of 2D polar materials that possess different types of chemical bonding nature, e.g., chemical bonds …

Chloramine Devulcanization Of Waste Rubber., Patrick Kroeger

Electronic Theses and Dissertations

The disposal of waste rubber, particularly tire rubber, continues to pose a challenge in the 21st century. As a result, most end-of-life tires (ELTs) are either dumped in landfills or burned as tire-derived fuel. Chloramine devulcanization may offer a viable solution to this problem. Chloramine devulcanization is a low-temperature, low-pressure, process that selectively breaks sulfur crosslinks while preserving the polymer backbone. Chloramine devulcanization enables the recovery of chloramine recovered carbon black (CrCB) and devulcanized rubber (CdR) as separate products. Initial analysis of CdR revealed that it was formable and malleable, suggesting that crosslinking was absent. Spectroscopy showed that CdR contained …

Land Tenure And The Urban Institutional Politics Of Sustainability: How Sustainability "Lands" In The Relationships Between Global North And South Contexts., Lindsey Connors

Electronic Theses and Dissertations

Sustainability is not simply a moral concept but is essential for human survival, and the tensions inherent in sustainable development bear repercussions that are increasingly placed onto the poor and powerless (Redclift 1987). While sustainability has become a relevant concept for urban knowledge and research especially in the global South, much of our urban sustainability knowledge is shaped by research and typologies from the global North (Nagendra et al. 2018; Parnell & Robinson 2017; Roy 2005). This dissertation considers the spatial transferability of sustainability knowledge from a relational perspective (Massey 2002). Sustainable development can be understood from this perspective as …

The Association Of Long Working Hours And The Use Of Prescription Sedatives Among U.S. Workers., Emmanuel Ezekekwu

Electronic Theses and Dissertations

BACKGROUND: Meeting the needs of a round-the-clock and globalized society has led to an increase in long working hours. This trend has been accompanied by a corresponding rise in sleep disorders and subsequent use of sedating medications. Overtime hours have been associated with adverse health outcomes such as cardiovascular diseases, symptoms of psychological distress, and health behaviors, including risky intake of alcohol and smoking. Hence, the main objectives of this three-paper dissertation were to examine the multi-faceted relationship between working hours, the use of prescription sleep aids, the onset of psychological distress, and the use of health care services.

Identifying And Analyzing Multi-Star Systems Among Tess Planetary Candidates Using Gaia, Katie E. Bailey

Electronic Theses and Dissertations

Exoplanets represent a young, rapidly advancing subfield of astrophysics where much is still unknown. It is therefore important to analyze trends among their parameters to learn more about these systems. More complexity is added to these systems with the presence of additional stellar companions. To study these complex systems, one can employ programming languages such as Python to parse databases such as those constructed by TESS and Gaia to bridge the gap between exoplanets and stellar companions. Data can then be analyzed for trends in these multi-star exoplanet systems and in juxtaposition to their single-star counterparts. This research was able …

A Score Of Voices: Creating And Scoring An Original Film With A Cappella Choir, Zachary James Moore

Electronic Theses and Dissertations

Film scores typically feature large instrumental ensembles, sometimes with choir added at pivotal moments. Rarely, however, is the choir entrusted with a greater percentage of the score, and far too scores explore the sonic potential that vocal music has to offer. In fact, in a recent study of 800 films, none contained a score that was completely c. Thus, the body of unaccompanied choral film scores is practically non-existent. This curious gap in repertoire inspired me to create the documentary Downstream (2023) and score it entirely with an unaccompanied choir. The full score to this new work is contained within …

Neonate Atlantic Sharpnose Shark (Rhizoprionodon Terraenovae) Relative Abundance And Body Condition In Two South Carolina Estuaries Varying In Urbanization, Rileigh E. Hawk

Electronic Theses and Dissertations

Urbanization near estuaries has been shown to affect the growth and survival of juvenile sharks using the system as a nursery. North Inlet and Murrells Inlet, South Carolina, are similarly-sized, tidally-dominated, bar-built estuaries with extensive Sporobolus-lined tidal creeks but differ in degree of human impact. Previously, Murrells Inlet was shown to have a lower abundance and diversity of large sharks than North Inlet and Atlantic Sharpnose Sharks (Rhizoprionodon terraenovae) were shown to use North Inlet as a primary nursery. To examine potential differences in neonate shark abundance and growth between a developed estuary, Murrells Inlet, and a protected estuary, North …

The Majority As The Minority: A Single Case Study Exploring Campus Environment And The Retention Of Racial Minority Students Attending A 2-Year Technical Hbcu In South Carolina, Meaghan Sharon Avery

Electronic Theses and Dissertations

The existing retention literature focuses on White students and non-White students in predominantly White institutional (PWI) environments. Furthermore, prevailing literature tends to concentrate on varying factors that influence these students to be retained at their respective institutions. Retention factors in differing contexts, such as historically Black colleges and universities (HBCUs), have been studied to a much lesser degree. Moreover, even fewer studies exist on how the campus environment at 2-year HBCUs influences retention or departure. Using a qualitative case study methodology, this study explores how the institutional environment of a rural southern 2-year technical HBCU influences the retention of racial …

The Underrepresentation Of African American Students In Ap And Honors Courses In Wilks County School District, Ivy Collins Palmer

Electronic Theses and Dissertations

Across the nation, research has shown that in an Advanced Placement (AP) class almost anywhere in the United States, it is likely to have the same phenomenon: a class made up primarily of white, middle- and upper-class students (Jeffries & Silvernail, 2017). Limited access to rigorous coursework for students from low socioeconomic households and minority groups can affect the number of minorities who matriculate to top research universities (Baylor, 2016). Access to AP and honors courses opens up new opportunities for students and pushes them toward success and future aspirations (McCauley, 2007). The problem is the African American (AA) population …

Early Instruments In 21st Century Composition And An Original Composition For Saxophones And Viols, Jacob Bitinas

Electronic Theses and Dissertations

Composers continually seek new timbres and sonorities to bend to their will. The early music revival of the twentieth century has resurrected dozens of instruments that have gone unutilized in contemporary composition for centuries. The historically-informed-performance movement has now evolved to a point where early instruments and period performance techniques can add extraordinary new characters to twenty-first century compositions. This thesis explores how composers effectively utilize early instruments like the viola da gamba, harpsichord, lute, and recorder in their compositions.

The document also contains interview transcripts from eight composers and performers, including Nico Muhly, Liam Byrne, Martha Bishop, David Loeb, …

Ethics And Contemporary Leadership: Do Ethical Leadership Theories Align With Scripture?, Anthony Scott Poston

Electronic Theses and Dissertations

Morals, ethics, and values are instrumental for leaders to know and choose between right and wrong. Leadership theories regularly discuss ethics, but where do these ethics come from? Frequently, the source of leadership ethics is glossed over or left out entirely. This study sought to address this gap in contemporary leadership literature by answering the question: how do contemporary leadership theories, which contain morals, ethics, and/or or values components, align with similar themes found within the Hebrew and Christian scriptures? The researcher used a thematic analysis of contemporary leadership literature to identify ethical themes within the literature. Next, the themes …

Enestr¨Om-Kakeya Type Results For Complex And Quaternionic Polynomials, Matthew Gladin

Electronic Theses and Dissertations

The well known Eneström-Kakeya Theorem states that: for P(z)=∑_i=0ⁿ a_i zⁱ, a polynomial of degree n with real coefficients satisfying 0 ≤ a₀ ≤ a₁ ≤ ⋯≤ a_n, all zeros of P(z) lie in |z|≤1 in the complex plane. In this thesis, we will find inner and outer bounds in which the zeros of complex and quaternionic polynomials lie. We will do this by imposing restrictions on the real and imaginary parts, and on the moduli, of the complex and quaternionic coefficients. We also apply similar restrictions on complex polynomials with …

Use Of Space And Foraging Behavior Of Loggerhead Shrikes In Urban Areas, Katie Anne Maddox

Electronic Theses and Dissertations

Loggerhead shrikes, Lanius ludovicianus, are a declining grassland songbird native to North America. Land-use change has been associated with the decline of grassland bird species. However, the process of urbanization creates novel short-grass habitats reminiscent of shrikes’ natural habitats. Loggerhead shrikes have been observed living in developed areas, particularly in Southeastern coastal states. Understanding the long-term impacts of urban-dwelling on loggerhead shrike populations is vital to identifying whether urban areas offer refuge or act as an ecological sink for shrike populations.

In chapter one, I quantified the use of space by shrikes in urban habitats within Horry County, South …

In another study, only 19% of postsecondary students …

Ableism, Ableist Microaggressions, And Psychological Thriving: A Mixed-Methods Study Of College Students With Physical Disabilities, Tonya Barnhill Dawsey

Electronic Theses and Dissertations

Microaggressions are daily insults to individuals that communicate messages of exclusion, inferiority, and abnormality. The term microaggression was originally used to explain the experiences of racial minorities. This term has also been used to explain the experiences of other individuals with oppressed identities. More recently, the term ableist microaggression has been used to describe these types of experiences for individuals with disabilities. Like other oppressed groups, individuals with disabilities experience ableism through interpersonal discrimination which is often delivered in a subtle, ambiguous, and unintentional manner that is difficult to address. Qualitative studies in the field of education and disability studies …
