Reading Echoes Of Homer In Plato: Finding Philosophical Insights By Reading Plato's Dialogues As Poiēsis, Stephen R. Lasse Jun 2026

Reading Echoes Of Homer In Plato: Finding Philosophical Insights By Reading Plato's Dialogues As Poiēsis, Stephen R. Lasse

USF Tampa Graduate Theses and Dissertations

Reading Echoes of Homer in Plato: Assessing the legitimacy of the macro-level thesis that approaching Plato from the poetic tradition starting with Homer generates philosophical insights not available when reading his dialogues as the first installments in the Western tradition of philosophy. It begins by identifying equivocal nuances in the dramatic content of Plato’s dialogues that are left unexplored by the current standard approach that attributes a progressive developmentalist approach to Plato’s authorial intent before suggesting an alternative unitarian approach to Plato as an author who maintains an unchanged point of view throughout his corpus of work. It then identifies …


Disclosing Hunger: Predictors And Screening Strategies For Food Insecurity In Undergraduate University Students And Adults Contexts, Jocelyn Emily Jarvis Jun 2026

Disclosing Hunger: Predictors And Screening Strategies For Food Insecurity In Undergraduate University Students And Adults Contexts, Jocelyn Emily Jarvis

USF Tampa Graduate Theses and Dissertations

Food insecurity is a growing public health concern among college students in the United States, with prevalence estimates exceeding those of the general population. Despite the availability of campus, community, and federal food assistance resources, utilization remains low, suggesting that barriers extend beyond structural access. This dissertation examines the psychosocial, behavioral, and institutional factors that shape food insecurity disclosure and help-seeking behaviors among undergraduate students, guided by the Social Ecological Model (SEM).

This work includes three complementary studies. Study One presents a scoping review synthesizing 16 U.S.-based studies to identify psychosocial determinants of food assistance utilization among food-insecure adults. Findings …


Vestitus Auctoritate: Visual Representations Of Power In Late Roman Sicily, Angela L. Costello Jun 2026

Vestitus Auctoritate: Visual Representations Of Power In Late Roman Sicily, Angela L. Costello

USF Tampa Graduate Theses and Dissertations

This dissertation examines how Late Roman iconography of dress and appearance acted as visual bolsters of elite identity in the province of Sicily by engaging with two villas and their mosaic corpora: the Villa Romana del Casale, and the Villa Romana del Tellaro. Traditional Roman scholarship on power have focused on monuments, military achievements, and imperial building programs, and while these are all necessarily facets of Late Roman identity, there are valuable avenues left unexplored. Some, but not enough, attention has been given to the role of dress iconography during Late Antiquity. This study addresses this gap by investigating how …

USF Tampa Graduate Theses and Dissertations

Artificial Intelligence (AI) is quickly changing the competitive landscape of most industries, and understanding how to incorporate this technology into products, services, and processes is becoming crucial for firms. This dissertation presents three studies that address different strategic challenges that arose with the unfolding of AI. First, I study how multinational enterprises globalize the development of AI. I argue that concentrating AI development or globalizing it has different implications for supply chain responsiveness and operations complexity. I use a combination of a rare dataset on software presence across 45 countries and financial data to show that AI development globalization has …


Van Der Waals Interactions Through The Lens Of 2d Materials With Emphasis On Many-Body Effects, Thi Xuan Diem Dang Jun 2026

Van Der Waals Interactions Through The Lens Of 2d Materials With Emphasis On Many-Body Effects, Thi Xuan Diem Dang

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the long-standing challenge of accurately and efficiently modeling long-range electron correlations, with a particular focus on van der Waals (vdW) interactions. These interactions play an essential role in predicting the structure, stability, and functionality of molecular systems and condensed matter materials. Although Density Functional Theory (DFT) has become a robust cornerstone of computational materials science, traditional formulations of the theory frequently fail to capture dispersive interactions, leading to significant errors in determining interlayer distances, binding energies, and stacking configurations. These limitations become particularly pronounced in layered materials and vdW heterostructures (HSTs), where weak long-range correlations are sensitive …

Disability Stigma, Disability Identity, And Psychological Distress Among Young Adults With Disabilities, Dylan G. Serpas Jun 2026

Disability Stigma, Disability Identity, And Psychological Distress Among Young Adults With Disabilities, Dylan G. Serpas

USF Tampa Graduate Theses and Dissertations

Disability discrimination is positively associated with psychological distress. Internalized disability stigma or the extent to which negative beliefs about one’s disability become personally adopted is implicated as a mediator. Moreover, disability identity processes, including identity affirmation and rejection may shape downstream consequences of navigating disability discrimination and internalization processes. These relationships are particularly relevant among young adults with disabilities (YAWD) who navigate a critical developmental period characterized by identity formation and heightened perception to social evaluation. In this study, 233 YAWD aged 18 to 25 completed a cross-sectional survey measuring disability microaggressions, internalized disability stigma, disability identity (rejection and affirmation), …


Trophic Structure Of Reef-Fish Assemblages In The Eastern Gulf Of Mexico Varies By Depth And Reef Type, Jessica L. Van Vaerenbergh Jun 2026

Trophic Structure Of Reef-Fish Assemblages In The Eastern Gulf Of Mexico Varies By Depth And Reef Type, Jessica L. Van Vaerenbergh

USF Tampa Graduate Theses and Dissertations

Globally, marine ecosystems are increasingly threatened by anthropogenic stressors, leading to reef degradation, changes in reef-fish assemblages, and altered trophic structure. In this study, I investigated reef-fish underwater visual survey data collected over a decade (2013-2023) from paired natural and artificial reefs in the eastern Gulf of Mexico. I applied the novel Normalized Reef Status Index (NRSI) to evaluate how biomass was distributed across the three trophic categories (i.e., Lower Trophic Position (LTP; 2.0-2.9), Central Trophic Position (CTP; 3.0-3.9), and Upper Trophic Position (UTP; ≥4.0). This index is a metric to assess the ecological status of reef systems by investigating …

Children with autism spectrum disorder (ASD) frequently experience co-occurring emotional, behavioral, and mental health concerns that increase the need for accessible behavioral health services. Although schools often serve as an important point of access for behavioral health support, disparities in service utilization continue to exist. Limited national research has examined recent patterns of mental health service utilization among children with ASD using updated nationally representative data.

The purpose of this study was to examine mental health service utilization among children with ASD and determine whether utilization differed across demographic and socioeconomic groups. Secondary data from the 2021–2022 National Survey of …


Using The Good Behavior Game To Decrease Challenging Behavior In Children With Autism Spectrum Disorder, Andrea M. Babb Jun 2026

Using The Good Behavior Game To Decrease Challenging Behavior In Children With Autism Spectrum Disorder, Andrea M. Babb

USF Tampa Graduate Theses and Dissertations

Challenging behavior in school settings can negatively impact academic engagement, social relationships, and access to instruction. Previous research has shown that the Good Behavior Game (GBG) can improve academic performance and decrease challenging behavior. Generally, to play the GBG, the teacher establishes a set of rules (e.g., “remain seated during the lecture”) that the students should follow and divides the class into two teams. When a student on either team breaks a rule, the teacher gives that team a tally or hatch mark. The team with the fewest tallies at the end of the game wins a prize. The current …

Evaluating The Effects Of Response Cards On Active Student Responding And On-Task Behavior With Elementary Students Diagnosed With Autism And Other Disabilties, Joshua N. Alvarado

USF Tampa Graduate Theses and Dissertations

One of the most prominent difficulties that students diagnosed with autism spectrum disorder (ASD) face in their education is consistently engaging in on-task behavior and active participation during whole-class group instruction. The use of response cards is one method that has been demonstrated to have beneficial effects for increasing on-task behavior and active participation for students with disabilities. However, there is limited research on effects with students diagnosed with ASD, particularly elementary students. The purpose of this study was to evaluate the effects of two response card types to increase active student responding, on-task behavior and correct responding for elementary …

When “Mild” Isn’T Minor: Return-To-Work Challenges In Post-Stroke Mild Aphasia, Maya Berro

USF Tampa Graduate Theses and Dissertations

Return-to-work (RTW) is an important aspect of social participation and quality of life following stroke. However, limited research has explored the experiences of individuals with mild aphasia in the RTW process. This purpose of this qualitative study was to explore how individuals with post-stroke mild aphasia perceive their ability to RTW and identify factors that influence this process. Ten adults with mild or very mild aphasia participated in individual semi- structured interviews conducted via Microsoft Teams. Interview transcripts were analyzed using inductive thematic analysis. Three major themes emerged: (1) Barriers to RTW, (2) Facilitators to RTW, and (3) Perceptions of …

Exploring Culturally Responsive Leadership Practices Among Female Leaders In Title I Schools: Strategies For Enhancing Student Success, Tara K. Indar

USF Tampa Graduate Theses and Dissertations

The academic achievement gap between White students and diverse student populations remains a persistent and prominent disparity in schools across the United States. While this issue affects schools nationwide, it is particularly significant in Title I schools, where many students from diverse, lower-socioeconomic-status backgrounds are served. Although a substantial body of literature examines this gap and highlights the positive impact of culturally responsive leadership, there remains a limited understanding of which specific practices are most effective in improving students’ academic outcomes. This study explores the perceptions of female school leaders in Title I schools regarding the strategies they believe contribute …


Modeling And Mitigating Stale Hardcoded Secrets In Version Control History, Katarina Valentine Capalbo Jun 2026

Modeling And Mitigating Stale Hardcoded Secrets In Version Control History, Katarina Valentine Capalbo

USF Tampa Graduate Theses and Dissertations

Hardcoded secret vulnerabilities remain a growing and persistent problem that can be difficult to mitigate once exposed. While there has been significant research and advancements in identifying and preventing hardcoded secrets, less attention has been given to understanding the risks of leaving these secrets behind in version control history, as well as analyzing the sanitization of hardcoded secrets. These challenges present a growing gap between the risk and ability to mitigate and sanitize existing secret exposures. This thesis begins to address this gap by formalizing a threat model for hardcoded secrets that persist in Git version control history after the …


Affect And Identification In Hereditary And Huesera: A Critique Of Neoliberal Motherhood In Post-Horror, Jared M. Lamanati Jun 2026

Affect And Identification In Hereditary And Huesera: A Critique Of Neoliberal Motherhood In Post-Horror, Jared M. Lamanati

USF Tampa Graduate Theses and Dissertations

This thesis examines the implications of affect and identification in post-horror and the consequences they present for motherhood. Specifically, I argue Hereditary (Ari Aster, 2018) and Huesera (Michelle Garza Cervera, 2023) make use of their maternal protagonists to complicate spectatorial identification and critique the cruel attachments of neoliberalism which idealize a heteronormative, homogenous vision of mothering. Following David Church’s postulation of affect, neoliberalism, and the maternal melodrama as central to “post-horror,” I look towards Linda Williams’s and Lauren Berlant’s paradigms of pathos and sentimental politics. While Williams addresses the complicated pains and pleasures of pathetic identification in the maternal melodrama, …

Sam-1: An Assistive Robot For Remote Patient Monitoring, Aana Farhana Ahsan

USF Tampa Graduate Theses and Dissertations

The global aging population has increased the demand for caregiving, while the availability of caregivers has not grown at the same pace. These trends have contributed to disparities in consistent and accessible care for older adults and increased caregiver burden. Geriatric care robots have emerged as a promising solution to support older adults and reduce caregiver burden. Existing systems have been developed for a wide range of applications, including rehabilitation, social support, assistance with activities of daily living, therapy, and caregiver telepresence. This thesis presents the development of SAM-1, an assistive robot designed to support remote monitoring of older adults …


Evaluating Some Effects Of Exposure To Prompt Topographies On Intraverbal Acquisition Rates And Choice For Prompt Topographies, Isabella Zaccor Jun 2026

Evaluating Some Effects Of Exposure To Prompt Topographies On Intraverbal Acquisition Rates And Choice For Prompt Topographies, Isabella Zaccor

USF Tampa Graduate Theses and Dissertations

People with developmental disabilities often have communication deficits, which create challenges with functioning in everyday life, making it more difficult for these people to foster meaningful relationships and live an independent life. People with developmental disabilities may need a more structured approach to learning important skills such as communication and social skills, such as learning with prompt topographies. By replicating Roncati et al. 2019, which evaluated exposure to prompt topographies and the effect on acquisition rates, we evaluated an adapted alternating treatments design within a multiple baseline across participants design to examine whether exposure to a specific prompt topography changed …


Discourse Production And Its Relationship To Cognition In Mild Aphasia, Marcy D. Edwards Jun 2026

Discourse Production And Its Relationship To Cognition In Mild Aphasia, Marcy D. Edwards

USF Tampa Graduate Theses and Dissertations

Objective:Standardized assessments such as the Western Aphasia Battery-Revised do not reliably detect subtle language impairments in mild aphasia (Dalton & Richardson, 2015). Discourse tasks may provide a more sensitive measure of impairment. Although discourse tasks differ in cognitive demands (Kim & Kintz, 2024), variation in discourse performance across tasks and the influence of cognition remains unclear. Therefore, this study examined (1) whether discourse performance differs across different discourse elicitation tasks, and (2) the extent to which cognition influences discourse performance in individuals with mild aphasia.

Participants & Methods: Fifteen participants with mild aphasia participated (mean age = 62.7 years). Discourse …


Exploring Menstrual Cycle Experiences And Well-Being In Young Women With Type 1 Diabetes, Yolanda Rotzinger Ballesteros Jun 2026

Exploring Menstrual Cycle Experiences And Well-Being In Young Women With Type 1 Diabetes, Yolanda Rotzinger Ballesteros

USF Tampa Graduate Theses and Dissertations

Young women with type 1 diabetes (T1D) navigate complex physical, emotional, and social challenges, being at a higher risk for mental health concerns (e.g., depression), as well as physical (e.g., fatigue) and cognitive (e.g., focus) symptoms related to the management of their chronic health condition (Dantzer et al., 2003; Northam et al., 2005). About one-third of young women with T1D experience some form of menstrual dysfunction (Griffin et al., 1994; Schweiger et al., 2011), which is associated with lower quality of life across several domains, including the educational setting (Knox et al., 2015). Nevertheless, there is a gap in the …


Moving Through Disasters: Spatial Analysis And Modeling Of Evacuation, Migration, And Socioeconomic Selectivity In The United States, Xiang Li Jun 2026

Moving Through Disasters: Spatial Analysis And Modeling Of Evacuation, Migration, And Socioeconomic Selectivity In The United States, Xiang Li

USF Tampa Graduate Theses and Dissertations

Disasters increasingly affect population movement in the United States, but their relationships with mobility and migration at various spatio-temporal scales are not fully understood. Disaster-related movement may appear as short-term evacuation during hazardous events, long-term migration after major or repeated disaster exposure, or selective redistribution across socio-economic groups. Therefore, this dissertation aims to address three main questions: 1) What are the spatial patterns of evacuation, and how do evacuation rates vary across space during a major disaster? 2) To what extent are natural disasters associated with long-term human migration patterns in the United States, and how can their contributions be …


Evaluating Generalization-Enhanced Behavioral Skills Training To Teach Firearm Safety Skills To Children With Autism, Victoria Alvarez Jun 2026

Evaluating Generalization-Enhanced Behavioral Skills Training To Teach Firearm Safety Skills To Children With Autism, Victoria Alvarez

USF Tampa Graduate Theses and Dissertations

Due to the large number of firearm-related incidents and the high percentage of households that own firearms in the United States, it is crucial that children learn firearm safety skills. Although previous research has evaluated various procedures for teaching firearm safety skills to typically developing children, there is a limited amount of research evaluating these interventions for children with autism spectrum disorder (ASD). The current study evaluated the effectiveness of a generalization-enhanced behavioral skills training (BST) procedure, which included varied training settings and tangible reinforcers, to teach firearm safety skills to children with ASD. We evaluated generalization-enhanced BST and in …

Listener Factors In Integrating Syntax And Plausibility In Sentences Produced With Versus Without Stuttering, Gabriella L. Burgess Hayes

USF Tampa Graduate Theses and Dissertations

Purpose: Development of communication-focused therapy for people who stutter requires better understanding of how stuttering impacts oral comprehension. One aim was to investigate how stuttering impacts listeners’ ability to integrate syntax and world knowledge (plausibility) in sentence processing. A second aim was to investigate how listener factors predict ability to integrate information in sentences with stuttering.

Methods: 224 adults heard 24 experimental sentences interspersed with 24 fillers. Experimental sentences included six plausible double-object dative (DO) constructions, six plausible prepositional dative (PD) constructions, six implausible DO constructions, and six implausible PD constructions. Implausible constructions served as analogues of communication breakdowns. Half …


Understanding The Impact Of Minority Stress On Mental Health Among Racially And Ethnically Diverse Adults: Insights From A Daily Diary Study, Ruba S. Rum Jun 2026

Understanding The Impact Of Minority Stress On Mental Health Among Racially And Ethnically Diverse Adults: Insights From A Daily Diary Study, Ruba S. Rum

USF Tampa Graduate Theses and Dissertations

Minority stressors are theorized to contribute to mental health disparities for racial and ethnic minority individuals. While prior research links distal (i.e., external) and proximal (i.e., internal) minority stressors to adverse psychological outcomes for racial and ethnic minority groups, most studies have relied on cross-sectional designs that limit understanding of the immediate and short-term effects of minority stressors and potential protective factors in daily life. To address this gap, the present study examined the within-person daily associations between distal (interpersonal and vicarious discrimination, microaggressions) and proximal (internalized stigma, anticipation of rejection, identity management) minority stressors and psychological outcomes. Racial and …


Prosocial Behaviors As A Protective Factor Against Suicide Risk: An Ecological Momentary Assessment Approach, Bradley A. Brown Jun 2026

Prosocial Behaviors As A Protective Factor Against Suicide Risk: An Ecological Momentary Assessment Approach, Bradley A. Brown

USF Tampa Graduate Theses and Dissertations

Suicidal ideation (SI) fluctuates substantially over short timescales, and the Interpersonal Theory of Suicide proposes that suicidal thinking emerges through dynamic interpersonal states involving perceived burdensomeness (PB), thwarted belongingness (TB), and hopelessness regarding these interpersonal states (IH). Although ecological momentary assessment (EMA) research has demonstrated that these risk factors fluctuate meaningfully within individuals and are associated with short-term changes in SI, comparatively little research has examined interpersonal processes that may attenuate suicide risk in real time. Prosocial behavior — voluntary actions intended to benefit others — may represent one such process, yet no known EMA study has examined whether prosocial …


Measures Of Linguistic Complexity And Vocabulary Diversity As Indicators Of Oral Language Production Growth Of 4th Grade Spanish-Speaking Els, Carla T. Zayas-Santiago Jun 2026

Measures Of Linguistic Complexity And Vocabulary Diversity As Indicators Of Oral Language Production Growth Of 4th Grade Spanish-Speaking Els, Carla T. Zayas-Santiago

USF Tampa Graduate Theses and Dissertations

As fourth-grade students transition from learning to read to reading to learn, their ability to use language for academic purposes becomes increasingly important, particularly for Spanish-speaking English Learners (ELs). However, students often have limited opportunities to produce extended oral language during instruction. Students’ oral language production reflects both structural aspects of language use, captured through measures of linguistic complexity, and lexical aspects of language use, captured through measures of vocabulary diversity. Although prior studies have examined transcript-derived measures of oral language production, limited research has examined how these measures predict English proficiency, capture growth over time, and respond to different …

In underserved urban communities, however, stormwater ponds are sometimes neglected and underutilized, leading to public health and environmental justice challenges. Our research in Tampa, Florida, seeks to develop pathways for residents and other stakeholders to collaboratively co-design infrastructure interventions and pondscape redevelopment for neglected stormwater ponds. Drawing on ethnographic and participatory methods as well as environmental assessment and modeling, we are working with residents of one pond community on cleanup and redevelopment strategies. Results reveal that balancing local and …


Polygenic Risk Scores, Sex, And Socioeconomic Factors As Predictors Of Age Of Onset For Major Depressive Disorder, Kaitlyn M. Nowak Jun 2026

Polygenic Risk Scores, Sex, And Socioeconomic Factors As Predictors Of Age Of Onset For Major Depressive Disorder, Kaitlyn M. Nowak

USF Tampa Graduate Theses and Dissertations

Major Depressive Disorder (MDD) is a heterogeneous psychiatric condition influenced by genetic, sociodemographic, and environmental factors, yet the extent to which these factors jointly shape the timing of disease onset remains unclear. This study evaluated the effects of polygenic risk scores (PRS), sex, and socioeconomic status (SES) on age of onset for MDD across two independent cohorts: the Pharmacogenomics Research Network Antidepressant Medication Pharmacogenomics Study (PGRN-AMPS) (N = 486) and the All of Us Research Program (N = 8,014). Analyses were restricted to individuals of European genetic ancestry, and PRS were constructed using both European-ancestry (EA) and multi-ancestry (MA) genome-wide …


The Architecture Of Chemical Understanding: How Representation Selection, Ordering, And Feature Salience Shape Students' Conceptions In Chemistry, Isaiah Nelsen Jun 2026

The Architecture Of Chemical Understanding: How Representation Selection, Ordering, And Feature Salience Shape Students' Conceptions In Chemistry, Isaiah Nelsen

USF Tampa Graduate Theses and Dissertations

Chemical representations play a central role in how students learn and reason aboutchemistry. While representations are routinely used in chemistry classrooms, students often struggle to extract relevant information, connect representations to underlying chemical principles, and apply this information to problem-solving. This dissertation investigates the role of representations in supporting students’ conceptual understanding and reasoning across general and organic chemistry through three qualitative studies.

The first study in this work explores how variation in chemical representation influences how students understand foundational chemistry principles. This study sought to characterize how second semester general chemistry students approach dipole–dipole interaction tasks with four distinct …


The Heterogeneous Response Of Astrocytes In Different Brain Regions Under Metabolic Stress, Pawan Kumar Thapaliya May 2026

The Heterogeneous Response Of Astrocytes In Different Brain Regions Under Metabolic Stress, Pawan Kumar Thapaliya

USF Tampa Graduate Theses and Dissertations

Astrocytes play a central role in maintaining ionic homeostasis, neurotransmitter clearance, and brain en-ergy metabolism. Their excitability, reflected in activity-evoked intracellular sodium (Na+, [Na+]i) and calcium (Ca2+,[Ca+]i) dynamics, is increasingly recognized as a critical determinant of neuronal function and vulnerability, particularly under metabolic stress. Despite their importance, the mechanisms underlying astrocytic ionic signaling and its regional heterogeneity remain incompletely understood. In this thesis, I developed detailed computational and biophysical models to investigate astrocytic Na+ and Ca2+ dynamics, their bioenergetic consequences, and the roles of key ion transporters under physiological and metabolically stressed conditions, validating the models against experi- mental data. …


Motivating Lung Cancer Screening Uptake: An Experimental Test Of Didactic Versus Narrative Messages For Lung Cancer Screening Among Individuals Who Currently Smoke Or Formerly Smoked, Honor M. Woodward May 2026

Motivating Lung Cancer Screening Uptake: An Experimental Test Of Didactic Versus Narrative Messages For Lung Cancer Screening Among Individuals Who Currently Smoke Or Formerly Smoked, Honor M. Woodward

USF Tampa Graduate Theses and Dissertations

Lung cancer is the number one cause of cancer-related death in the United States and worldwide. Lung cancer screening with low-dose computed tomography (LDCT) has been associated with a 20% reduction in lung cancer-related mortality. Despite the obvious benefits of lung cancer screening with LDCT, screening is heavily underutilized compared to other cancer screening tests. Thus, it is critically important to develop strategies that help motivate screening uptake among eligible individuals. This study explored the effectiveness of narrative messages for motivating lung cancer screening uptake among individuals eligible for lung cancer screening who currently smoke or formerly smoked. Drawing from …
