Factors And Attributes Contributing To The Longevity Of Special Educators: Over 15 Years Of Commitment, Susan Majestic-Frabell

Electronic Theses and Dissertations

This study investigated the personal, professional, and institutional aspects that contribute to special education teachers' resilience, dedication, and professional identity in southwestern Pennsylvania. Ten participants used Interpretative Phenomenological Analysis (IPA) to explore how moral purpose, empathy, relational engagement, mentorship, professional competence, and continual learning help them stay committed throughout time. The findings show that teaching is regarded as a vocation based on advocacy, service, and optimism, rather than a mere employment. Systemic supports, such as access to school-based mental health specialists, inclusive decision-making frameworks, reasonable workloads, and equitable policies, have emerged as crucial for lowering emotional burden, increasing efficacy, and …

Moreover “Speak It into Existence” highlights the synergetic and systematic characteristics of the African American Prophetic Tradition which speaks to the entirety of the individual mind, body and soul. Rooted inside the field of prophetic rhetoric, the African American Prophetic Tradition affirms the social, political and sacred realities of prophetic rhetoric. The rhetorical theology of the African American Prophetic Tradition rhetorically transfers the social, political, and sacred realities of prophetic rhetoric into its own systematic foci of liberation, transformation …

The African American Pulpit And The Reconstruction Of Narrative Ground In The Black Community, Nathaniel Cox

Electronic Theses and Dissertations

This dissertation explores how the African American pulpit serves as a living wellspring for rebuilding stories, memory, and identity, a task made urgent by centuries of erasure, from the trauma of the Middle Passage to the ongoing reverberations of that violence. My central claim is that African American preaching, when viewed through the insight-rich frameworks of Gadamer, Burke, and Frankl, becomes not just a form of speech, but a lifeline. It helps reclaim "narrative ground": the deep roots of meaning, belonging, and shared purpose that nourish a wounded people and allow genuine flourishing.

The journey unfolds across six movements. Chapter …

Values-Based Clinical Ethics: A New Model Of Health And Ethics Consultation For Patients Suffering In Extremis, Adam Trainer

Electronic Theses and Dissertations

This dissertation argues that contemporary clinical ethics is inadequately equipped to support patients suffering in extremis because it relies on an insufficiently discriminating account of health and a constrained model of moral reasoning. Drawing on Bernard Lonergan, it reconceives health as an emergent, multi-layered, heuristic notion shaped by biological, psychological, social, and existential goods. On that basis, it critiques principlism’s global applicability thesis and the undergirding claim that its principles form part of the common morality, arguing that this justificatory structure is philosophically insufficient and practically limited for clinical ethics in cases marked by profound suffering, moral plurality, and normative …

Pedagogy In Context: How Private School Teachers Make Meaning Of Equity-Focused Teaching Practices, Savannah Shana Scarborough

Electronic Theses and Dissertations

This pedagogical ethnography examines how teachers in a private school context understand and enact Culturally Relevant Education (CRE). While CRE emphasizes cultural competence and critical consciousness, less is known about how it is interpreted within private school settings, where institutional culture and community expectations shape pedagogy. This study explores how teachers engage culturally relevant commitments and how institutional context influences those practices.

A qualitative ethnographic design was used to examine classroom practice in a South Carolina private school. Data was collected through observations, semi-structured interviews, and teacher reflections from four Upper School teachers selected through purposive sampling. Analysis combined deductive …

Unc-45b As A Potential Chaperone For The Transcription Factor, Gata-4, Kaylah Owings

Electronic Theses and Dissertations

The cardiac myosin–specific chaperone UNC-45B has been shown to physically interact with the cardiac myosin transcription factor GATA-4. Specifically, this interaction occurs within the chaperoning region of UNC-45B, known as the UCS domain. However, the precise nature of this interaction has not yet been fully elucidated. The present study was conducted to confirm earlier findings and to evaluate whether UNC-45B functions as a chaperone for GATA-4 using bioinformatic approaches. Analysis of the interaction using AlphaFold 3 modeling verified not only that binding occurs at the UCS (chaperoning) domain of UNC-45B, but also that the interaction is associated with an increase …

Adsorption Of Pfas On Bridged Functionalized Organosilica Materials, Elisha Lawerh Kabutey

Electronic Theses and Dissertations

PFAS are hazardous contaminants that have a devastating impact on human health and the environment. Their hazardous nature has led to the development of various adsorption methods for removing these contaminants from water sources. In this study, functionalized organosilica materials were synthesized from bis[3-(trimethoxysilyl)propyl] amine using the sol-gel method. The surface amino groups of the organosilica were converted into amine hydrochloride groups. Their adsorption properties were evaluated using salts of perfluorooctanoic acid, perfluorooctanesulfonic acid, and perfluorobutanesulfonic acid. Results showed excellent adsorption capacity of the materials. Adsorption of PFAS leads to particle agglomeration and flotation of the spent material. A column …

Does Self-Compassion Buffer Against The Potential Effects Of Perfectionism And Psychopathology On Non-Suicidal Self-Injury?, Natasha Bourgoin

Electronic Theses and Dissertations

University students with increased rates of reported perfectionism, anxiety, and depression, are vulnerable to non-suicidal self-injury (NSSI). However, not all students with psychological distress engage in NSSI, suggesting protective factors may help to mitigate this risk. The present study examined the relation between perfectionism and NSSI, via the mediating effects of anxiety and depression, and the moderating role of self-compassion. Participants were 338 university students (67% female; 87% White) who completed several self-report measures. Students with greater perfectionism reported higher levels of anxiety and depressive symptoms and, in turn, more NSSI engagement. Self-compassion and several self-compassionate domains attenuated connections between …

The Southampton Plot: The Case For Innocence (1415), Haley Buckles

Electronic Theses and Dissertations

This thesis investigates the "Southampton Plot" of 1415, a famous conspiracy to overthrow King Henry V of England. While history often portrays the plotters as simple traitors against the government, this study reexamines original records to show a more complex story. By looking closely at how the English government handled the trials, the research reveals that the English Crown may have exaggerated the threat to strengthen the King’s political power before he invaded France. This study shows that what we call "treason" was often shaped by the government’s need to control its public image and hold on to power. Ultimately, …

Atmospheric Remote Sensing Using X-Band Radar In The Marine Atmospheric Surface Layer, Daniel P. Greenway

Electronic Theses and Dissertations

Atmospheric remote sensors have always offered promising technological advancements for measuring atmospheric properties over large spatial areas at high spatiotemporal resolution – a feat not currently possible with present atmospheric measurement technologies. However, remote sensors do not measure these atmospheric properties directly; they rely on robust calibrations or conversions, complex mathematical inversion methods, and/or machine learning to retrieve these properties. These inverse methods rely on the selection of an objective function, a machine learning technique, and an accurate parameterization for atmospheric property estimation. By leveraging inverse methods to improve the characterization of properties measured by remote sensors, this work enables …

Stability Of Paraffin-Insulated Nitrogen-Doped Carbon Fiber Ultramicroelectrodes, Maxwell H. Kwakwah

Electronic Theses and Dissertations

Nitrogen-doped carbon materials can facilitate the reduction oxygen-oxygen bonds, a key step in electroreduction of both O₂ (an important reaction in energy applications) and H₂O₂ (an important reaction in sensing and biosensing). Our lab previously demonstrated that thermal decomposition of urea in the presence of carbon fiber (CF) results in an N-doped carbon material that exhibits good electrocatalytic properties for H₂O₂ reduction. However, previous methods of insulating single N-doped CF via laser heating of borosilicate capillaries and epoxy to prepare ultramicroelectrodes (UMEs) seemed to adversely affect surface nitrogen contents and electrocatalytic properties. More recent work that utilized paraffin to …

Ccr5 Sulfopeptide Library And O-Glycosylated Amino Acids As Chemical Tools For Probing Chemokine Receptor Recognition, Mostafa Mohammed Mohammed Ali Eldeen

Electronic Theses and Dissertations

Chemokine-receptor interactions play a central role in immune regulation and disease pathogenesis, particularly through CCR5, a receptor engaged by chemokines such as CCL3, CCL4, and CCL5. Post-translational modifications of the CCR5 N-terminus—including tyrosine sulfation at positions 3, 10, 14, and 15, and O-glycosylation at serine 6—critically modulate chemokine recognition and selectivity. However, the impact of specific sulfation patterns on chemokine binding and the synergistic effects of combined sulfation and glycosylation remain incompletely understood. This thesis presents a two-project chemical approach to systematically investigate CCR5 post-translational modifications. In Project 1, a comprehensive 16-member library of CCR5???? sulfopeptides representing all possible combinations …

Study Of Binary Hypothesis Testing Using Deep Learning, Sadhana Geddam

Electronic Theses and Dissertations

Binary hypothesis testing is a fundamental problem in statistical signal processing and decision theory, with applications in communications, radar systems, and distributed sensor networks. Classical approaches, particularly the likelihood ratio test (LRT), provide optimal detection performance when the underlying probability distributions are known. However, in many practical scenarios, the resulting decision rules can become analytically complex or computationally intensive, especially in multi-sensor and dependent data settings.

This thesis investigates the use of neural networks for binary hypothesis testing under diverse statistical conditions. A data-driven framework is developed to learn decision rules directly from observed data, enabling the approximation of likelihood …

A Revised Quantifier Variance And Its Implications On Vagueness, Isaac Alexander Huling

Electronic Theses and Dissertations

This paper argues that the Special Composition Question has no substantive answer, not because compositional talk is empty but because the physical structure it tracks does not have the form that would privilege a unique answer. The argument accepts Sider’s methodological premise that the world must provide structure beyond description if ontological vocabulary is to mean anything, and deploys that apparatus against his specific application of it to composition. Constraint processes among a system’s parts – the forces and interactions that hold rigid bodies together, maintain organisms, bind solar systems – satisfy every condition Lewis required of reference magnets. They …

Murdoch's Metaphorical And Mystical Moral Metaphysics, William Jade Langley

Electronic Theses and Dissertations

In this project, I explain the mysticism found in Iris Murdoch’s The Sovereignty of Good, emphasizing what the illustrative thought experiments and metaphors are meant to explain. To do this, I introduce her understanding of G. E Moore’s moral realism and compare this with how Bertrand Russell understands mystical intuition and revelation. Then, to understand how we can still do moral philosophy when morality is fundamentally mystical, I compare Murdoch’s usage of metaphor with that of Victoria Welby, who also takes metaphorical understanding to be crucial to our understanding of the world. Though Welby goes further than Murdoch in saying …

Semantically Grounded Evaluation For Open-Vocabulary Human-Object Interaction Detection, Maja Noack

Electronic Theses and Dissertations

Open-vocabulary human–object interaction (HOI) detection is a step towards building scal¬able systems that generalize to unseen interactions in real-world scenarios and support grounded multimodal systems that reason about human–object relationships. However, stan¬dard evaluation metrics, such as mean Average Precision (mAP), treat HOI classes as dis¬crete categorical labels and fail to credit semantically valid but lexically different predictions (e.g., “lean on couch” vs. “sit on couch”), limiting their applicability for evaluating open-vocabulary predictions that go beyond any predefined set of HOI labels. I introduce SHOE (Semantic HOI Open-Vocabulary Evaluation), a new evaluation framework that incorporates semantic similarity between predicted and ground-truth …

A Phenomenological Study: Examining Organizational Change Initiatives Within The U.S. Army To Influence Racial Climate, Reginald Gerald Dash Ii

Electronic Theses and Dissertations

This research study was aimed at examining organizational change initiatives influencing the racial climate among African American soldiers in the United States (U.S.) Army. African Americans comprise a significant portion of the U.S. Army. However, African Americans’ significant contributions do not readily translate into “equal treatment”, which includes proportional representation at the highest levels of leadership. African Americans in the U.S. Army face career navigation challenges rooted in systemic racial division. The goal of this qualitative phenomenological study was to add African American soldiers’ voices to the existing literature by interviewing African American soldiers with at least five years of …

Electronic Theses and Dissertations

Career and Technical Education (CTE) programs are designed to prepare students for high-wage, high-demand industry jobs. However, there is limited research on Career and Technical Education teacher preparation programs (traditional, alternative, and industry-based) and the impact on student outcomes on industry-based examinations, such as ACT WorkKeys. This quantitative study analyzed Career and Technical Education (CTE) teacher preparation programs (traditional, alternative, and industry-based) and 12th -grade students’ outcomes on the 2023-2024 ACT WorkKeys examination and whether relationships exist between the two. Additionally, the research examined each Career and Technical Education teacher certification preparation program individually to determine the differences among traditional, …

Staying In Stem?: A Qualitative Exploration Of Women’S College Classroom Experiences In Stem Education, Sarah Dapaah

Electronic Theses and Dissertations

Women leave STEM not because of a lack of ability, but because of the classroom and institutional conditions they encounter once they arrive. This study examines how classroom experiences shape women’s decisions to persist in or leave STEM majors at the college level. Drawing on the sociological frameworks of doing gender, gendered organizations, and intersectionality, this study explores how gender, race, and class shape women’s experiences of belonging, support, discouragement, and recognition in STEM. Using 21 semi-structured interviews and 4 classroom observations at the University of Mississippi, the study analyzes the experiences of undergraduate women who remained in STEM, women …

Mining The Body: Racial Capitalism And The Embodied Sacrifice Zone, Regina Marie Young

Electronic Theses and Dissertations

Mining the Body: Racial Capitalism and the Sacrifice Zone of the Body examines 20th and 21st-century American literature, excavating the ways in which mining not only extracted resources from the earth, but also mined the bodies of their workers for their labor, often ignoring safety in the name of economy. This extraction of coal and of labor, along with its attendant exploitations, sparked unionization and labor movements throughout the century, as miners were frequently at the forefront of asserting their rights in response to this treatment. Using a framework that relies on both environmental criticism, such as Rob Nixon’s Slow …

Examining The Relationship Between Co-Curricular Programming And Burnout Among Medical Students At An Academic Medical Center, Lauren Williams

Electronic Theses and Dissertations

This three-manuscript dissertation examines the relationship between co-curricular programming and burnout among Doctor of Medicine (MD) students at the University of Mississippi Medical Center (UMMC), situating the issue within broader concerns about physician well-being and institutional responsibility.

Manuscript I establishes the conceptual and empirical foundation for the study by reviewing the prevalence, consequences, and theoretical framing of burnout in medical education. Drawing on Maslach’s three-dimensional model of burnout—emotional exhaustion, depersonalization, and reduced personal accomplishment—and Astin’s Student Involvement Theory, the manuscript situates co-curricular engagement as a potential protective factor against distress. The literature review highlights alarming rates of depression, suicidal ideation, …

Read Again, Succeed Again, Kaitlin Martz

Electronic Theses and Dissertations

This study examined the effects of a repeated reading (RR) intervention on the oral reading fluency and comprehension of first grade students identified as “at-risk” in a high poverty school in the Mississippi Delta. Students from low socioeconomic status (SES) backgrounds often have limited early literacy experiences, which contributes to persistent achievement gaps in reading (Romeo et al., 2022; NAEP, 2024). This study is grounded in LaBerge and Samuels’ (1974) theory of automaticity to employ an intervention focused on building reading fluency as a means to improve reading comprehension.

Six students participated in one-on-one sessions three times per week for …

Investors' Perceptions Of Audit Workload And Experience Disclosures, Tara L. Baggett

Electronic Theses and Dissertations

I employ a 3 x 2 between-subjects experiment to examine how audit experience and workload disclosures impact non-professional investors’ perceptions of audit quality. Consistent with implications for actual audit quality, I predict and find that non-professional investors perceive audit quality to be higher when disclosures report more experienced auditors. Workload, though, is more susceptible to variations in interpretation, with the possibility of discrepant effects. I identify and explore two potential interpretations of workload, effort and overwork, finding support for both, and as predicted, I find evidence that these interpretations differentially affect non-professional investors’ perceptions of audit quality. Interpreted as overwork, …

Retail Investor Responses To Accounting Disclosures Using Trade-Level Evidence, Matthew Oakes

Electronic Theses and Dissertations

Retail trading is experiencing remarkable growth amongst the current capital markets driven by many advancements such as commission free trading, fintech applications, and fractional share trading. Prior literature documents differing opinions on the capabilities of retail traders, often describing these traders as noise or attention-based traders. Whether these investors trade on complex accounting information remains an empirical question. In this study, I investigate whether retail investors respond to and incorporate accounting disclosures in their trading decisions by examining financial restatements, going concern opinions, and material weakness disclosures. I analyze retail activity using the quote midpoint method and fractional share trades. …

Institutional Strain And Substance Coping: Analyzing Perceived Racial Discrimination As A Predictor Of Adolescent Marijuana Use, Fahad Bin Islam Khan

Electronic Theses and Dissertations

This study examines the relationship between perceived racial/ethnic discrimination, psychological distress, and youth marijuana consumption through the lens of the General Strain Theory. It uses the complete-case sample from the 2023 Youth Risk Behavior Survey (YRBS), which surveyed 17,268 high school students across the United States, in a cross-sectional study. The study used logistic regression analyses to assess the association between perceived racial or ethnic bias (e.g., actual discriminatory experiences), psychological distress, and substance use (marijuana), and how closely emotional stress linked these two phenomena. The results indicate that perceived discrimination has a significant positive association (greater likelihood) with both …

Adversarial Llm-Gans For Robust Synthetic Pharmaceutical Data In Self-Emulsifying Drug Delivery Systems, Samiul Islam Niloy

Electronic Theses and Dissertations

The formulation of self-emulsifying drug delivery systems (SEDDS) represents a pivotal advancement in improving the oral bio-availability of poorly water-soluble pharmaceutical compounds, yet traditional development is heavily hindered by limited experimental datasets and the complexity of predicting key quality attributes like nanoparticle size and drug release profiles. Because empirical methodologies struggle to balance formulation constraints with predictive accuracy, this research introduces a comprehensive framework that leverages state-of-the-art generative artificial intelligence to synthesize realistic, constraint-compliant SEDDS datasets. The study proposes two primary methodologies to overcome data scarcity: a novel Drug Formulation Agent (DFA) powered by Large Language Models (LLMs) and a …

Iterative Decoding For Sccpm With Markov And Hidden Markov Sources, Zhijie Guo

Electronic Theses and Dissertations

Continuous Phase Modulation (CPM) is an excellent digital modulation scheme recognized for its constant envelope property, continuous phase transitions, and inherent memory. These characteristics enable excellent spectral and power efficiency, allow compatibility with nonlinear amplifiers, and make CPM particularly attractive for power- and bandwidth-constrained applications such as satellite and deep space communications. Serially Concatenated Continuous Phase Modulation (SCCPM) with iterative decoding further improves error performance, and its flexibility enables it to evolve alongside state-of-the-art channel coding technologies and show significant potential for performance enhancement.

This dissertation investigates SCCPM systems with binary Markov and Hidden Markov Model (HMM) data sources and …

Development And Evaluation Of Ros-Responsive Thioketal-Capped Mesoporous Silica Nanoparticles For Dual Drug Delivery Of Moxifloxacin And Curcumin In Wound Healing, Saiganesh Pothuraju

Electronic Theses and Dissertations

Chronic infected wounds remain a major clinical challenge because elevated reactive oxygen species (ROS) in the wound microenvironment sustain inflammation, damage regenerating tissue, and limit the effectiveness of conventional antimicrobial and anti-inflammatory therapy. To address this problem, this study aimed to develop ROS-responsive thioketal-capped mesoporous silica nanoparticles (TK-MSNs) for the dual delivery of moxifloxacin (MOX) and curcumin (CUR) to support the management of infected wounds. Mesoporous silica nanoparticles (MSNs) were synthesised using tetraethyl orthosilicate (TEOS) and cetyltrimethylammonium bromide (CTAB), followed by template removal, amino-functionalization with 3-aminopropyltriethoxysilane (APTES), and sequential loading of MOX and CUR. ROS-responsive capping was then achieved using …

Predicting Future Positions Based On Spatiotemporal Data, Andrew John Heskett

Electronic Theses and Dissertations

This thesis examines how different multi-agent prediction architectures perform when forecasting future player positions in soccer using only ball and player coordinate data, with-out relying on pretrained knowledge of soccer rules or tactical concepts. Spatial positioning is a fundamental part of soccer and is often a defining characteristic of high-level players. However, there is still no fully deterministic method for evaluating how effectively a player uses space. As multi-agent trajectory prediction methods have improved over the last decade, it has become increasingly feasible to develop systems that can analyze and eventually grade player movement. A necessary first step toward that …
