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 …

Temporally Modulated Acoustic Environment Alters Inferior Colliculus Tonotopy And Improves Neural Gap Encoding In Aged Cba/Caj Mice, Luis Franco-Waite

USF Tampa Graduate Theses and Dissertations

Age-related hearing loss (ARHL) is an omnipresent and progressive decline of hearing that occurs later in life and affects a significant majority of the aged population. While the current accommodations for hearing loss focus on improving comfort and quality of life, they do not address the underlying neural aspects of ARHL. A novel approach for treatment is the augmented acoustic environment (AAE) which utilizes the innate plasticity of the nervous system in response to the external environment. The work presented here documents the research performed on passive noise exposures which target neural aspects in animal models of age-related hearing loss. …

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. …

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), …

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 …

The Molecular Determinants Of Deglycation And Substrate Specificity In Fructosamine Kinases, Jenet Matlack

USF Tampa Graduate Theses and Dissertations

Protein glycation is a universal, non-enzymatic modification that occurs when a sugar covalently attaches to a primary amine. These spontaneous modifications may have deleterious or regulatory effects on protein function, and their removal is mediated by the conserved metabolic kinase fructosamine-3-kinase (FN3K). Despite its crucial role in protein repair, we currently have a poor understanding of how FN3K engages or phosphorylates its substrates. Additionally, the molecular basis for the distinct yet overlapping substrate specificities of FN3K and its paralog, ketosamine-3 kinase (KT3K), remains unresolved. By integrating structural biology, biochemistry, and ancestral protein reconstruction (APR), this thesis elucidates the catalytic mechanism …

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 …

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 …

Gnsi Decision Brief: The Three-Body Trap: The New Geometry Of Nuclear Deterrence, Seong-Hyon Lee

GNSI Decision Briefs

In the astrophysics of orbital mechanics, the “Two-Body Problem” – predicting the gravitational interaction between two objects, such as the Earth and the Moon – is mathematically solvable. The system is stable, the orbits are predictable, and the variables are calculable. However, if a third independent object of sufficient mass is introduced, the system becomes non-linear and highly unpredictable. As proven by mathematician Henri Poincaré in 1887, no single formula can solve for long-term stability in a three-body system. For eight decades, since the dawn of the nuclear age, global security operated on “Two-Body” physics. The United States and the …

The Theatrics Of Political Representation: Homestyle, Boundary Work, And Emotional Labor Among Florida Legislators, Donald E. Mullins

USF Tampa Graduate Theses and Dissertations

This dissertation examines how political representation is performed and sustained in the Florida Legislature. Rather than treating representation primarily as votes, bills, or policy outcomes, it approaches it as interactional work through which legislators remain believable, accessible, and authoritative across overlapping audiences. Grounded in an interpretivist epistemology and Goffman’s dramaturgy, the study develops an ethnographic account of representation through three analytic anchors: Fenno’s homestyle, Lamont’s boundary work, and Hochschild’s emotional labor. Methodologically, the project draws on ~100 days of participant observation during the 2025 legislative season, hundreds of pages of fieldnotes, and semi-structured interviews with ten Florida legislators. The findings …

Encouraging A United Response: A Systematic Review And Mixed-Methods Collaborative Evaluation Of Co-Responder Model Effectiveness In Florida, Kelsey Greenfield

USF Tampa Graduate Theses and Dissertations

Even before the deinstitutionalization movement caused the influx of state hospital patients into communities ill-prepared to navigate their needs, law enforcement has been responsible for responding to persons in crisis (PIC) due to mental illness. In response to the high rates of incarceration for persons with mental illness (PMI), a growing number of law enforcement agencies have adopted diversion strategies referred to as police-mental health collaboration (PMHC) models to divert PMI away from the criminal justice system and towards community mental health services. Despite nearly forty years of research, there are still considerable knowledge gaps regarding who benefits from PMHCs …

Additionally, this case study enabled exploration of the research questions across six types of master’s programs within the College of Education. By focusing on the first year of graduate study, …

The Dynamic Nature Of Comprehensibility During Itas’ Oral Language Performances, Tania Ferronato

USF Tampa Graduate Theses and Dissertations

In U.S. academic settings, everyday oral multilingual interactions can pose communicative challenges (Gass & Varonis, 1984), which can be understood and addressed by looking into communicative dynamics. Exploring the construct of comprehensibility, the perceived ease or difficulty in understanding self and others’ speech (Munro & Derwing, 1995a), through a dynamic lens (Nagle et al., 2019; Trofimovich et al., 2022) helps gaining insights into interlocutors’ subjective experiences to better understand the more social nature of successful real-time communication. This is fundamental in linguistically diverse classroom settings where L2 English speakers can be employed as International Teaching Assistants (ITAs) to teach undergraduate …

Speleoco: An Open, Low-Cost Arduino Co₂ Datalogger For Cave Microclimate Monitoring, Christos Pennos, Dimitrios Christaras

International Journal of Speleology

Carbon dioxide (CO₂) dynamics in caves are critical for karst processes, speleothem growth and dissolution, microclimate regulation, and caver safety. In cave atmospheres, CO₂ commonly derives from soil respiration, epikarst degassing, microbial activity, and, in tectonically active regions, deep-seated fault-related emissions. Fault-related CO₂ degassing may also track tectonic activity. However, continuous monitoring remains limited due to the cost and inflexibility of commercial instruments. Here we present an open-source, low-cost Arduino-based CO₂ datalogger designed for cave applications. The logger integrates a COZIR NDIR CO₂ sensor, a DS1337 real-time clock, microSD storage, and power-gating for extended deployment in humid environments. Firmware and …

Mismatched Music And Meams: Short-Form Social Media Videos And Social Attitude Messaging, Kaitlyn M. Serafin

USF Tampa Graduate Theses and Dissertations

“If the formative power in the media are the media themselves, that raises a host of large matters” (McLuhan, 1964, p. 10). Famed communications theorist Marshall McLuhan stated this all the way back in the 60s to explain how technology can act as a formative force in the messaging of media. This is because the medium in which they communicate the messaging can act as its own force, shaping the message like clay. The dominant media at the time of this theory was television; however, in the past decade social media and short-form social media videos have become dominant forms …

Is There No Such Thing As Bad Pr? A Case Study Analysis Of Influencer Pseudo-Events, Authentic Crises, And Crises As Opportunity, And Paracrisis, Sofia Aparicio-Gallagher

USF Tampa Graduate Theses and Dissertations

There's no such thing as bad PR, and any publicity is good publicity are phrases coined by 19th-century P.T. Barnum, a showman and businessman known for his circus hoaxes (Hiergesell, 2025). The idea implies that all media attention, whether negative or positive, is beneficial to the organization or individual. The purpose of this study is to evaluate three brands; Tarte, Poppi, and Shein during a brand event to determine whether it was a pseudo-event created to gain awareness, or a genuine, unplanned crisis. Another purpose of the study was to determine if the event was used as an opportunity for …

A Look At The Potential Impacts Of Priming Thoughts Through The Show Family Guy, Thomas Wiskoff

USF Tampa Graduate Theses and Dissertations

This study examined whether brief exposure to a death-themed episode of the adult animated show Family Guy could prime viewers to adopt less serious attitudes toward death and dying. Drawing primarily from priming theory, with supporting insights from cultivation and framing theories, the research focused on the show's unique use of magical realism and irreverent humor, particularly the personification of Death as the sarcastic Grim Reaper, to explore potential shifts in death-related attitudes. Participants (N = 100) were randomly assigned to view one of two clips from Family Guy Season 2, Episode 6 ("Death is a Bitch") with one clip …
