This dissertation achieved the following objectives: (1) developed a patient-centered access to pharmacies framework; (2) evaluated the impact of pharmacy closures on immunization rates among Medicare beneficiaries; and (3) examined the influence of state-level pharmacy benefit manager (PBM) regulations on rates of pharmacy closures.

For objective 1, a grounded theory methodology was used to identify a patient-centered access to pharmacies framework (PcAP). This framework asserts that patients determine whether they have access to a pharmacy through evaluation of their characteristics, the characteristics of pharmacies, and their own needs or values within the context of a health-related need. This evaluation of …

The Underrepresentation Of African American Male Educators In K-12 Education, Nisa Lewis Johnson

Electronic Theses and Dissertations

The American education system has struggled with a significant teacher shortage for years. Alongside this shortage is the underrepresentation of African American male teachers. Despite the increasing diversity of the student population, African American men make up less than 2% of teachers nationwide (Aftunion, 2020). This disparity denies all kids access to diverse perspectives in the classroom and limits the presence of role models for students of color. Research studies have shown that African American students who have African American teachers show improvement in their grades, standardized test scores, attendance records, and graduation rates (Breazeale, 2023). This study aimed to …

Asking Pharmacists About Over-The-Counter Oral Contraceptives: Intention Among Adolescents And Young Women, Ivy Leong

Electronic Theses and Dissertations

The recent availability of over-the-counter oral contraceptives eliminates many barriers to accessing birth control. Even with this easier accessibility, pharmacists can still play an important role in educating users, especially adolescents and young adults. However, hesitation to reach out to pharmacists among younger populations has been documented. Additionally, little is known about the underlying driver of this hesitation.

This study aimed to examine predictors of young females’ willingness to seek assistance from pharmacists for over-the-counter oral contraceptive use and to determine the difference in the effect of these predictors between adolescents (age 16 to 17) and young women (age 18 …

Exploring Aging And Bone Health In Normal Weight Obesity And The Prevalence Of Unhealthy Lean Phenotypes, Pouria Sefidmooye Azar

Electronic Theses and Dissertations

Obesity is a complex chronic condition characterized by the excessive accumulation of body fat. While numerous studies have highlighted the risks of adverse complications associated with obesity, limited research has explored the relationship of body composition phenotypes, more specifically normal weight obesity with aging, and bone health. Also, the prevalence of unhealthy lean phenotypes in adults in the U.S. is not clear. A secondary-data analysis of the National Health and Nutrition Examination Survey (NHANES) 1999-2002 were performed to further examine the relationship between body composition phenotypes—normal weight lean (NWL), overweight/obesity with normal body fat percentage (OBL), normal weight obesity (NWO), …

A Profile Of Contempt: Its Expressive Function In The Age Of Profilicity, Eric Michael Servatius

Electronic Theses and Dissertations

Contempt permeates modern political discourse and popular media. Nevertheless, within the psychological and philosophical literature on reactive attitudes, moral emotions, and negative sentiments, contempt remains comparatively understudied. In this paper, I examine contempt’s intimate connection with social identity and argue that existing accounts of contempt largely overlook the broader social role it plays in a contemporary moment characterized by digital communication and fluid group dynamics. I contend that public expressions of contempt serve two primary expressive functions in modern society: (1) to signal group identification and (2) to enforce group norms—not for the target of contempt, but for third party …

Electronic Theses and Dissertations

Transvestia magazine was important for the creation of the modern transvestite community. This project shows how the editor of the magazine defined her readership and how the stories, letters to the editor, and advertisements published within the magazine helped to develop this sense of community within the readership. The contents of the magazine were tabulated into spreadsheets and counted along with relevant data, including word counts, what issues the items appeared in, where they appeared inside the magazine, etc. The first five years of the magazine were compared with the last five years, showing how it changed editors, length, frequency, …

Slope Stability Hazard Investigation Of Calhoun County, Mississippi And The County Road 210 Landslide, Miles Heath Grames

Electronic Theses and Dissertations

This thesis uses geological field data, laboratory characterization of sediments, and multiple computational models of slope stability to investigate a landslide that occurred in Calhoun County, Mississippi. The primary hypothesis is that intense rainfall led to the saturation of the slope, triggering failure through the reduction of shear strength.

Fieldwork included drilling at the failure site to obtain subsurface samples and drone-based site characterizations. Laboratory analysis included soil descriptions, grain size analysis, and Atterberg limit testing. Sample characterizations revealed a stratified soil profile dominated by fine-grained silts and clays, including an organic-rich lignite layer (OL). Strata generally exhibit low permeability …

Partitions Into Sums Of Two Squares And Gaps Between Zeros Of L-Functions, Jaime Hernandez Palacios

Electronic Theses and Dissertations

This work consists of two distinct problems. In the first one, we use a variation of the Circle Method, along with ideas coming from the Saddle Point Method, to obtain an asymptotic formula for the number of partitions of a number n into integers which are sums of two squares. In the second problem, we discuss some new results for large and small gaps between the ordinates of zeros of high degree zeta and L-functions, including Dedekind zeta-functions associated with Galois extensions of Q and principal automorphic L-functions.

Leveraging The Zebrafish Model For The Study Of Human Health Impacts Of Particulate Matter Exposure: Exploring Biological Effects Of Fuel Source Emissions, Autism Spectrum Disorder-Like Behaviors, And Molecular-Level Reproductive Impacts, Shayla Victoria

Electronic Theses and Dissertations

Particulate matter (PM) is the solid and liquid portion of air pollution that can be found at various size fractions, including PM2.5, which is 2.5 μm or smaller in aerodynamic diameter. PM is a complex mixture, containing a wide variety of chemical constituents, including inorganic compounds (heavy metals), organic compounds (polycyclic aromatic hydrocarbons), and pesticides, that have been individually linked to human health impacts. These include cardiovascular and respiratory conditions, but due to its small size and chemical composition, PM has the ability enter into systemic circulation and cause dysregulation of other physiological processes, such as neurodevelopment and reproduction, which …

From Difficult Heritage To A Symbol Of Peace: A Case Study Of The Chibondo Mass Grave In Zimbabwe., Peter Mudzingwa

Electronic Theses and Dissertations

This thesis examines the contested interpretation and memorialization of the Chibondo mass grave in Zimbabwe, analyzing how unresolved historical grievances shape national reconciliation efforts. Discovered in 2011, Chibondo became a politically charged heritage site, officially framed as a symbol of liberation while simultaneously raising allegations that it contains victims of post-independence violence, including the Gukurahundi massacres. Employing the theoretical frameworks of difficult heritage, transitional justice, and memorialization, this research explores the political, social, and ethical complexities that emerge when nations confront traumatic pasts. Through a mixed-methods approach that combines semi-structured interviews, direct observations, and scholarly reviews, the study critically assesses …

Human Papillomavirus Knowledge, Beliefs, And Behaviors Among Community College Students: Why Should It Matter?, Eric Pittman

Improving Detection Capabilities Of Traditional Machine Learning (Ml) Algorithms Against Data Poisoning Attacks On Image Data, Sabrina Perry

Electronic Theses and Dissertations

Machine learning (ML) algorithms play a critical role in automated decision-making systems across domains such as healthcare, finance, and autonomous systems. However, these models are increasingly vulnerable to adversarial threats, particularly poisoning attacks that manipulate training data without the knowledge of the ML developers. As ML models are often trained on publicly available data, data poisoning is trivial for attackers to perform, with no way to determine if training data is legitimate, poisoned during data collection, or poisoned during training in the current ML training pipeline.

This dissertation investigates data poisoning attacks, with a focus on label flipping and gradient …

Comparative Analysis Of Out-Of-Pocket Expenditures On Authorized Generics And Independent Generics Among Medicare Beneficiaries, Arman Arabshomali

Electronic Theses and Dissertations

Background: Authorized generics (AGs) are essentially brand-name drugs without the brand name on their labeling. AGs are often marketed as cost-saving alternatives to brand-name drugs; however, their impact on patient out-of-pocket (OOP) expenditures compared to independent generics (IGs) remains understudied, especially within Medicare. This study investigates the OOP costs of AGs versus IGs among Medicare beneficiaries with Part D coverage.

This study examined the predictive value of college entrance exams specifically the ACT and SAT on the academic retention of domestic, first-time, full-time freshmen at the University of Mississippi. With the rise of test-optional admissions models, particularly during and after the COVID-19 pandemic, this research investigates whether standardized test scores remain relevant in forecasting student success, defined by persistence from freshman to sophomore year and academic performance measured through GPA in the first and second semesters. Drawing upon a conceptual framework that includes pre-college characteristics, standardized assessments, and early academic performance, this study challenges the long-held assumption that standardized exams …

Don't Let Them In: Our Vampire Stories In The French Quarter, Sela Ricketts

Electronic Theses and Dissertations

This thesis is an exploration of vampires in New Orleans. The reason I have chosen to include the word “Our” in the title is because we created the stories that I am studying. We created, perpetuated, changed, and eventually monetized them. Throughout this paper I discuss how the vampire came to New Orleans and how that same vampire shows up in New Orleans folklore. Then I discuss how the vampire made the jump from urban legend to pop culture. In doing that it gained “humanity”. They were still monstrous, but it was enough humanity to acquire regional identity, a southern …

The Effects Of Validating And Invalidating Responses On Self-Reported Levels Of Anxiety, Leila Sachner

Electronic Theses and Dissertations

Given that validation and invalidation have been linked to internal factors contributing to anxiety disorders, it is important to further explore how validation and invalidation are associated with experiences of anxiety. The current study was designed to assess the association between validation/invalidation and anxiety among college students. Significant omnibus regression models emerged revealing that perceived invalidation accounted for 25.7% of the variance in self-reports of physiological anxiety symptoms and 27.6% of the variance in self-reports of generalized anxiety symptoms. A series of mixed-factorial ANOVAs revealed no main effect of experimental condition on emotional responses (anxiety, anger, arousal, valence), indicating that …

Data-Driven Modeling Of Levee Failure: A State-Of-The-Art Approach For Integrating Artificial Intelligence Techniques With Hydraulic Erosion And Geotechnical Characterization, Haitham O. Saleh

Electronic Theses and Dissertations

Flooding is one of the most destructive natural disasters in the United States, often resulting in catastrophic damage to communities and infrastructure. The primary flood-protection structures, earthen dams and levees, are critical for mitigating these impacts. In Mississippi alone, there are over 2,800 dams and 3,750 miles of levees along the Mississippi River and its tributaries. Of this, nearly 2,200 miles are along the mainstem Mississippi River, with the remaining levees situated along backwaters, tributaries, and floodways. Understanding the erosion behavior of these structures during overtopping events is essential for accurate failure prediction and risk assessment. This study focuses on …

Beliefs And Factors That Influence Female College Students’ Decision To Consume Weight Loss Products, Cynthia Ummay Siddiqua

Electronic Theses and Dissertations

Background: Rising societal pressures, body image concerns, and the increasing accessibility of commercial weight loss products (WLPs) have led to heightened use among young women, particularly college students. Female undergraduates are especially vulnerable due to social media influence, peer comparison, and transitioning lifestyles. Despite the popularity of WLPs, concerns persist regarding their safety, efficacy, and the psychosocial beliefs driving their use. This study seeks to understand the beliefs and factors influencing WLP consumption among female college students using Social Cognitive Theory (SCT) and the Health Belief Model (HBM).

Distress Tolerance And Links With 24-Hour Ambulatory Blood Pressure, Colter K. Clayton

Electronic Theses and Dissertations

Cardiovascular disease is a leading cause of death in the United States. Hypertension is a major modifiable risk factor for cardiovascular related morbidity and mortality. Psychosocial factors are associated with blood pressure control and preliminary evidence has linked greater distress tolerance to lower blood pressure. The present study examined associations between distress tolerance and key blood pressure markers (24-hour mean blood pressure, nocturnal dipping) among community-dwelling adults (N = 60) using the noninvasive gold standard of blood pressure measurement—ambulatory blood pressure monitoring. Separate hierarchal linear regression analyses did not reveal any significant relationships between distress tolerance and 24-hour mean systolic, …

Comprehensibility, Accentedness, And Intelligibility Of English Varieties As Perceived By Japanese Learners Of English, Kana Machida

Electronic Theses and Dissertations

In response to Japanese learners of English having limited exposure to various English accents in education, this study investigates their comprehensibility, accentedness, intelligibility, and familiarity with different accents. Twelve participants evaluated how easy speakers were to understand and the extent of their accentedness, and transcribed their speech.

Quantitative analysis revealed that Japanese learners of English struggle with understanding certain accented varieties of English, particularly Nigerian English, and are unfamiliar with them. In contrast, General American English and Southern American English speakers were generally perceived as less accented and easier to understand. However, results from the listening transcription task indicated that …

The Stories Of Land: Exploring Southeast Indigenous Historical Contextualization In University Settings, Haley Elizabeth Mcglone

Electronic Theses and Dissertations

Institutions of Higher Education have a unique opportunity as educational spaces to connect with the land they occupy. As students enter the college environment, institutions have a responsibility to provide them with meaningful connection to land their university is situated upon and educate them in its history. Many institutions of higher education have incorporated important contextualization projects on their campuses in an effort to acknowledge and confront their historic ties to colonization and systemic racism (Ruth J. Simmons Center for the Study of Slavery and Justice, n.d.).
