Iron Deficiency And Depressive Symptoms: Effects Of Racial And Ethnic Disparity In Two Reproductive-Aged Us Women, Alexis Monkhouse

USF Tampa Graduate Theses and Dissertations

Problem: Reproductive- aged women are one of the populations most at risk for iron deficiency and depression in the United States. While many studies have looked at the relationship between these two illnesses, none have explored it from a biocultural framework, examining how race/ethnicity affects this relationship. Using data from NHANES, this thesis examined the relationship between iron status (total body iron) and depressive symptoms (PHQ-9) among reproductive-aged women in the U.S. and how race/ethnicity affects it. Methods. NHANES survey data from 2005-2010 were pulled. Demographic and laboratory data were used to determine eligibility, total body iron, and depressive scores. …

Prosecutorial Philosophy And Racial Disparities In Arrest Rates, Carl L. Reeds

USF Tampa Graduate Theses and Dissertations

The prominent issue of racial disparities in arrest in the criminal justice system is well documented. One proposed mechanism for addressing these disparities in the criminal justice system is the emergence of progressive prosecutors. Progressive prosecutors are vastly different than traditional prosecution through the approach to their roles in the criminal justice system. Traditional prosecutors prioritize convictions and punishment, often seeking maximum sentences for defendants and relying on the traditional model of tough-on-crime policies. Progressive prosecutors pledge to reform the criminal justice system by declining to prosecute certain low-level offenses, expanding diversion programs, and explicitly addressing racial and socioeconomic disparities. …

District Leadership Influence On The Sustainability Of Dual Language Bilingual Education Programs, Jessica Hessler

USF Tampa Graduate Theses and Dissertations

Dual language bilingual education programs operate within policy environments that often constrain their long term viability, despite their deep historical roots in the United States. This qualitative study examined how district/central office leadership systems supported the sustainability of these programs. While prior research has emphasized school site collaboration between principals and teachers, limited attention has been given to the district/central office level leadership systems and strategies that shaped program coherence, implementation, and endurance. Guided by a framework integrating social justice leadership with principles of sustainable leadership, the study examined the research question: How do district or central office leadership systems …

Netflix, Between Intercultural Exchange And Monopolizing Tendencies: Streaming Consumption, Production, And Distribution In Romania, Ana-Maria Calancea

USF Tampa Graduate Theses and Dissertations

This thesis examines the development and involvement of the SVOD platform Netflix in Romania in the context of a global media corporation engaging with a local market. Romania’s status as a former communist country acts as a good case study highlighting the long-term consequences of diverse content deprivation. I argue that in a country such as Romania, a service like Netflix can provide a so-called indirect intercultural exchange through the production and distribution of easily accessible diverse content, whether that diversity stems from nationality, ethnicity, race, sexuality, or any unconventional form of expression that was restricted or censored in the …

Clinical Features, Laboratory Characteristics, And Outcomes Of Covid-19 Patients In A Tertiary Care Reference Hospital In Panama City, Panama. A Retrospective Observational Study, Santiago E. Hernandez Bojorge

USF Tampa Graduate Theses and Dissertations

Latin America experienced some of the world’s highest COVID-19 mortality rates, yet data on in-hospital outcomes and their social and geographic determinants remain limited. This dissertation investigated multilevel baseline factors associated with in-hospital mortality among adults with COVID-19 at Panama’s largest public tertiary hospital (Hospital Santo Tomás), integrating survival, mediation, and spatial-temporal modeling within a causal-inference framework.

A retrospective cohort of 1,526 RT-PCR–confirmed COVID-19 hospitalizations (May 2020–November 2021) was analyzed using multivariable Cox proportional-hazards, Fine–Gray competing-risk, mediation, and Bayesian spatial models. Directed acyclic graphs (DAGs) pre-specified causal relationships and minimally sufficient adjustment sets. DAG-guided models quantified total effects without conditioning …

Merger Waves In A Small Open Economy: Industry Shocks, Behavioral Variables, Mergers And Acquisitions In Singapore, Eng Sian Quek

USF Tampa Graduate Theses and Dissertations

As an open economy, Singapore has experienced substantial transformations in its mergers and acquisitions (M&A) market over the past several decades, alongside evolving regulatory frameworks designed to maintain its position as a competitive international hub for corporate restructuring. Over the 20 years from 1990 to 2009, Singapore was exposed to a series of major economic shocks, including financial crises, geopolitical conflicts, terrorism, sectoral downturns, oil price shocks, and public health epidemics, all of which were accompanied by pronounced fluctuations in interest rates and equity market conditions. Against this backdrop, this dissertation examines the determinants of M&A waves in Singapore by …

Assessing The Impact Of Lampenflora Growth On Invertebrate Distribution And Food Resource Use In Ryusen-Do Cave, Japan, Kazuhide Nakajima, Kanato Ando, Shuji Watanabe, Masuo Komukai

International Journal of Speleology

Subterranean spaces, such as caves with openings to the surface, represent unique environments characterized by limited resources derived from photosynthetic primary production. Consequently, organic inputs from organisms inhabiting above- and belowground habitats, such as bats, play a crucial role in maintaining cave ecosystems. However, in show caves converted into tourist attractions, environmental changes have progressed without sufficient ecological assessment. One important factor is the impact of photosynthetic organisms colonizing around artificial lights, known as lampenflora, on cave ecosystems. Lampenflora growth may influence invertebrate distribution and resource use; however, its impact on both aspects has been poorly evaluated. In this study, …

Military Sexual Trauma And Suicidality: An Analysis Of Interpersonal Risk Factors, Jacquelyn Burckley

USF Tampa Graduate Theses and Dissertations

Suicide remains a major public health concern, particularly among military personnel and veterans, who experience elevated risk compared to civilian populations. Military sexual trauma (MST), defined as sexual assault or harassment during military service, is a significant risk factor for suicidality, yet less is known about how characteristics such as recency and revictimization influence suicide severity. This study aimed to examine the relationship between MST victimization and suicide severity and to evaluate whether the Interpersonal Theory of Suicide explains suicide severity among MST victims. Using data from a large military sample, logistic regression and mediation analyses were conducted to assess …

Exploiting Chaotic Antenna Arrays For Rf Fingerprint Authentication And Physical Layer Security In Wireless Communications, Joshua K. Thomas Ranstrom

USF Tampa Graduate Theses and Dissertations

Modern wireless networks support a wide range of applications including consumer devices, healthcare monitoring, industrial automation, smart grids, and military platforms, in which transmitted information is often highly sensitive and subject to stringent confidentiality and integrity requirements. As wireless communication operates over an open broadcast medium it exposes systems to physical layer (PHY) threats such as eavesdropping, in which an adversary passively intercepts transmitted information, and spoofing, in which a forged transmission misleads the receiver about device identity. Cryptographic defenses address both threats but require computational assumptions and key management infrastructure that may not scale to dense or resource-constrained deployments. …

Geospatial Understanding Of Foundation Models: Self-Supervision, Robustness, And Resource-Constrained Learning, Gilbert Kibet Rotich

USF Tampa Graduate Theses and Dissertations

Research on large-scale geospatial understanding from satellite imagery remains relativelyunderexplored. Much of the field still relies on narrow, task-specific pipelines, and there is lim- ited work on developing true foundation models or on systematically evaluating how well these models generalize under domain shift, geographic variation, and real-world scene diversity. This dissertation advances foundation-model pretraining and evaluation for remote sensing along three complementary axes. First, we develop self-supervised multispectral pretrained models for satellite image classification by adapting BYOL, BarlowTwins, DINO, MoCo, and Simsiam to multispectral inputs, addressing the limited amount of curated satellite datasets relative to ImageNet. Pretraining on Eurosat and …

Death And Things: Toward A Theory Of Self-Holding Objects, Kirsten J. Lee

USF Tampa Graduate Theses and Dissertations

This dissertation examines how material objects function as existential supports under conditions of cultural exclusion. Drawing on Terror Management Theory (TMT), minority stress theory, and José Muñoz’s concept of disidentification, it introduces the construct of self-holding objects: possessions imbued with identity-sustaining meaning that stabilize the self. Study 1 employed a qualitative photovoice design with 16 queer adults and identified five primary existential functions of meaningful objects: affirming worth, regulating the body, mirroring the self, authorizing possibility, and enabling worldmaking. These findings suggest that objects operate as material anchors within distributed systems of meaning. Study 2 experimentally tested whether imagining the …

Implementing A Brief Dialectical Behavior Therapy-Informed Skills Group In A County Jail: A Mixed Methods Approach To Understanding Feasibility And Acceptability, Meaghan E. Brown

USF Tampa Graduate Theses and Dissertations

Correctional institutions unintentionally function as one of the largest mental health providers in the country. Short-term facilities, like jails, present an opportunity to provide mental health care to those who will quickly reenter our communities. Despite this, evidence-based practices and treatments in correctional settings have been implemented at slower rates compared to community settings and mental health institutions. Regulating emotions, refraining from impulsive maladaptive behavior, and communicating effectively are considered primary treatment needs among jail inmates. Dialectical Behavior Therapy (DBT; Linehan, 1993) can address these deficits and is commonly implemented in a skills training group format in correctional settings; however, …

It’S Not Me, It’S U(Niversity): A Longitudinal Study Of The First-Generation Graduate Student Experience Navigating Privacy And Identity During Socialization, Melissa L. Mccormick

USF Tampa Graduate Theses and Dissertations

This longitudinal study examines the experiences of first-generation graduate students (FGGS; students whose parent(s) do not hold a 4-year undergraduate degree). Specifically, it considers how FGGS manage their private information throughout the first year of their graduate program, and how the intersection of their FGGS status with other aspects of their identity may shape those experiences (e.g. the overlapping of FGGS status, race, and socioeconomic status). While there is substantial research on the first-generation student experience at an undergraduate level, FGGS have largely been left out of the conversation (exception: Levin, 2022). Guided by theories of organizational socialization (Jablin, 1985), …

From Marginalization To Prime Consideration: Nuclear Energy In Fragmented Climate Governance, Polarization, And The Age Of Ai, Abdullah Al Jaberi

USF Tampa Graduate Theses and Dissertations

In recent years, nuclear energy has remained sidelined in global climate discussions despite being the world’s second-largest source of low-carbon electricity. This dissertation examined why nuclear energy should be the global priority decarbonization strategy, based on an evaluation of its unique position across the following three dimensions: fragmented international climate governance, political polarization in democratic countries, and unprecedented baseload electricity demands created by artificial intelligence infrastructure. This study does not argue causal linkages among these dimensions; rather, it demonstrates that nuclear energy succeeds concurrently across all three. A mixed-methods approach was employed, including document analysis of bilateral agreements and official …

Challenging The Deliberative Consensus: Participatory Strategies, Transparency And Citizen Trust Across Municipal Contexts, Fadel Al-Marsoumi

USF Tampa Graduate Theses and Dissertations

This dissertation examines the relationships between participatory governance strategies and multidimensional citizen trust in municipal contexts. Although local governments have implemented deliberative forums, digital platforms and hybrid participation approaches to restore declining public confidence, inconsistencies between theoretical predictions and empirical outcomes have raised questions about participatory governance effectiveness. Motivated by this gap between deliberative democracy theory's optimistic predictions and limited empirical support, the study investigates the psychological, political and contextual mechanisms that shape trust formation through civic engagement. Drawing on an integrated framework combining organizational trust theory and deliberative democracy frameworks, the research conceptualizes trust as a multidimensional construct involving …

A New Great Game?: Great Powers Content Re-Sharing And Media Influence In The South Caucasus, Emma A. Lowery

USF Tampa Graduate Theses and Dissertations

In the new digital era of geopolitics, competing great powers support internationally oriented state-sponsored media as integral parts of public diplomacy, seeking to reach foreign publics in an increasingly digital age of information sharing. Leveraging local outlets provides an avenue to influence local publics through pre-approved news. Targeted foreign news outlets actively engage with and re-share content from said media. This research focuses on foreign-originated content from the world’s great powers - the People’s Republic of China, the Russian Federation, and the United States of America. The purpose of this project is to provide insight into how the great powers …

Secure Machine Learning In Networking Systems, Wenwei Zhao

USF Tampa Graduate Theses and Dissertations

With the rapid integration of Machine Learning (ML) into networking systems, ensuring the security and trustworthiness of these intelligent frameworks has become a paramount concern. While ML offers unprecedented capabilities in spectrum management and collaborative learning, it also introduces novel vulnerabilities that can be exploited by sophisticated adversaries. This dissertation investigates and addresses critical security challenges across three key dimensions of ML-driven networking: adversarial spectrum sensing, the security of privacy-preserving unlearning processes, and efficient post-attack model recovery.

First, we address the threat of adversarial spectrum attacks in cognitive radio networks, where malicious nodes manipulate sensing reports to disrupt spectrum access. …

Critical Discourse Analysis Of Turnaround Leadership Competencies Using A Transformative Leadership Framework, Kevin D. Mcdonald

USF Tampa Graduate Theses and Dissertations

School turnaround leadership has become a leading strategy to address school underperformance emphasizing rapid and dramatic improvement in a school within the bottom five percent of schools as measured by gains in both mathematics and English Language Arts. However, prevailing turnaround leadership discourse largely centers technical and managerial competencies, often marginalizing leadership practices oriented toward equity, advocacy, and social transformation. This narrowing of leadership is particularly consequential for Black male principals, who are disproportionately assigned to low-performing and turnaround schools and whose leadership practice frequently reflects core elements of transformative leadership.

The purpose of this dissertation was to explore current …

Mentoring Mentalities Made Manifest: Toward A Better Understanding Of Secondary Teacher Mentor Professional Learning, Practice, And Self-Efficacy, Maggie L. Wilson

USF Tampa Graduate Theses and Dissertations

Teacher shortages are becoming increasingly problematic nationwide. Teacher mentoring has been found to be an effective method of curbing teacher attrition, but little attention has been addressed to ensuring that teacher mentors are receiving the most relevant professional learning experiences to bolster their self-efficacy and mentoring practice. This qualitative study, drawing on research traditions such as grounded theory and case study, seeks to illuminate the mentor self-efficacy and practice of secondary teacher mentors and to understand the role their professional learning plays in how and how well they enact their mentor roles. Through qualitative interviews, including artifact-based interviews, this study …

Mathematics Anxiety: Understanding Its Concept, Impact On Secondary Students’ Academic Performance And Career Prospects, And Effective Intervention Strategies, Sabiruddin Molla, Safwana Rashid, Saba Sultana

Numeracy

This study investigates the influence of mathematics anxiety on secondary school students’ academic performance and career pathway selection. Mathematics, often perceived as abstract and challenging, can evoke high levels of anxiety that affect both learning outcomes and career-related decisions. Data were collected from 106 students across two urban secondary schools in Kolkata. Findings revealed that students possessed a significant understanding of the concept of mathematics anxiety (t (105) = 8.48, p < .001, d = 0.82). A strong positive correlation was observed between mathematics anxiety and academic performance (r = .686, p < .001), indicating that elevated anxiety levels correspond with lower achievement. Additionally, a significant positive correlation (r = .475, p < .001) showed that mathematics anxiety influences students’ career pathway selection, with higher anxiety leading to avoidance of mathematics-related careers. The study highlights that negative attitudes toward mathematics often stem from perception rather than actual difficulty. Overall, the findings emphasize the need for innovative teaching strategies and targeted interventions to reduce mathematics anxiety and enhance students’ academic and career outcomes.

Teachers' Perspectives On The Inclusion Of Children With Autism In Preschool And Kindergarten Programs Within Inclusive Classrooms In Saudi Arabia, Budur Alsalamah

USF Tampa Graduate Theses and Dissertations

In recent years, Saudi Arabia has witnessed a significant increase in the number of students with autism being integrated into mainstream classrooms. This is thanks to laws and regulations enacted to provide appropriate education for students with special needs, particularly those with autism, in less restrictive environments. This is a positive step towards providing equal educational opportunities for students with special needs. However, teachers' views on integrating children with autism into mainstream education remain varied. Studies have shown that teachers with positive attitudes towards inclusion are more likely to provide inclusive education in the classroom (Dev & Hayes, 2015). This …

Using a qualitative multiple case study approach, the research analyzed media coverage, public statements, institutional communications, foundation announcements, and philanthropic records to identify recurring patterns in how ethical leadership and stakeholder responsibility were communicated during these crises. Guided by ethical communication theory, ethics of care, stakeholder theory, Situational Crisis Communication Theory (SCCT), and values-driven reputation management, the study explored how values were enacted through both communication and material action.

Findings indicated …

The Power Of A Princess: Rebranding For A New Generation, Victoria A. Heath

USF Tampa Graduate Theses and Dissertations

The lyric “Well, that sounds an awful lot like princess problems” from Snow White (2025) reflects Disney’s evolving portrayal of its princesses as more self-aware and independent. This shift is echoed in earlier live-action adaptations, such as Beauty and the Beast (2017), where Belle’s longing for “adventure in the great wide somewhere” signals her rejection of a limited, traditional role. Guided by Feminist Film Theory and media framing, this study examines how Disney’s rebranding of princess characters in Beauty and the Beast (2017), The Little Mermaid (2023), and Snow White (2025) reflects contemporary ideals of empowerment. Through narrative content and …

How Do Water Utilities Meet Growing Demand And Maintain Resilience Through Water Reuse? A Systems Thinking Approach, Elizabeth F. Vicario

USF Tampa Graduate Theses and Dissertations

Water and wastewater utility management is becoming increasingly complex due to factors like urbanization, climate change, new regulations, and rising costs. Utility leaders must balance competing political and financial pressures while managing aging infrastructure, rising demand, climate resilience planning, and customer concerns about affordability. Reuse of treated wastewater has emerged as a promising solution to address scarcity, declining source water quality, and new regulations on wastewater discharge in the United States. However, water reuse is not one-size-fits-all, and bespoke solutions are needed to optimize economic, environmental, and social returns from this finite resource. Despite growing interest, little is known about …

Making Sense Of The Body: Cognitive Science, Disability, And Embodiment, Cheyne L. Joslin

USF Tampa Graduate Theses and Dissertations

The purpose of this project is to analyze different methodological approaches in the philosophy of cognitive science, with the goal of determining their usefulness for explaining and understanding bodily awareness and skill-acquisition over time. The examples of skill-acquisition are limited to motor control, impaired by various kinds of disability—but then acquired over time, via technological or rehabilitative means. These phenomena of motor learning are then viewed through the lens of two competing theoretical approaches in cognitive science: neuromechanical cognitive science, and radical enactivist cognitive science.

The strengths of the neuromechanical framework are found in its historical pedigree, and in the …

Semiotics Of Difference: Language, The Body, And Haitian Personhood In The Dominican Republic, Benjamin Puterbaugh

USF Tampa Graduate Theses and Dissertations

The present dissertation is an ethnographic and multimodal semiotic analysis of the role of signs in the daily life of Haitians in the Dominican Republic (DR). I investigate how language and other embodiments of Haitian alterity are perceived and ascribed value by hegemonic social orders. I center the analysis on the popular perceptions of the Haitian person-type or characterological figure (Agha, 2003) as (over)determiners of actual Haitian subjectivity. I investigate the ways that Haitian personhood is translated, that is, perceived and assigned value, in the Dominican context, and the implications this has on realities of Haitian immigrants. In addition to …
