An Equity Analysis Of Battery Electric Vehicles During Evacuation Considering Social And Financial Disadvantage, Divyamitra Mishra

USF Tampa Graduate Theses and Dissertations

The increasing share of battery electric vehicles (BEVs) in the transportation system is introducing new challenges to the emergency evacuation planning and management. During Hurricane Milton (2024), incidents involving BEVs, including battery fires, attributed to saltwater exposure risk, and advisories recommending relocation to higher ground, highlighted operational vulnerabilities unique to this technology. These emerging risks are likely to be experienced heterogeneously, as access to charging infrastructure, available resources, and evacuation flexibility varies across the population. This raises critical questions about how BEV-specific constraints interact with existing inequalities during evacuation. Motivated by this context, the dissertation investigated inequity in BEV evacuation …

Unveiling The Intersection Of Institutional Racial Identity And Student Loan Debt: An Analysis Of The State University System Of Florida’S Higher Education Institutions, Valerie Marie Moore

USF Tampa Graduate Theses and Dissertations

Federal student loan patterns in Florida’s State University System (SUS) from 2013/14 to 2022/23 reflect differences in institutional revenue capacity rather than individual borrowing behavior. Using data from all 12 SUS institutions, this study examined how institutional wealth and revenue composition shape student loan outcomes through both race neutral and race considerate analyses informed by Ray’s (2019) theory of racialized organizations. Overall, the SUS operates as a racialized organizational field in which inequities in funding flows, access to capital, and institutional logics sustain long term disparities in wealth and debt. Results show that borrowing levels closely track how institutions assemble …

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. …

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 …

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 …

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 …

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), …

Housing Affordability Analysis Of Hillsborough County, Fl, Usa – Quantitative And Geographical Analysis Using Spatiotemporal Data, Bomin Koh

USF Tampa Graduate Theses and Dissertations

Housing affordability assessments rely on the 30 percent income method and generalized linear regression (GLR)-based hedonic price modeling. Both provide broad insights but fail to capture spatial heterogeneity in affordability challenges. This study upgrades housing affordability assessment approaches by incorporating the residual income method and Geographically Weighted Regression (GWR). The primary objective of this study is to determine whether methodological improvements, residual income method and GWR, yield significantly different results and provide a more accurate and spatially adaptive understanding of affordability dynamics in Hillsborough County, Florida.

The 30 percent income method is widely used and classifies households as cost-burdened if …

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 …

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 …

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 …

Coloring Outside The (Guide)Lines: Hispanic Race/Ethnicity, District Types, And Sentencing Outcomes In Immigration Offense Cases For Noncitizen Defendants, Paige S. Pagano

USF Tampa Graduate Theses and Dissertations

This thesis examines whether sentence length in federal immigration cases varies by Hispanic race/ethnicity, district type, and the intersection of the two among noncitizen defendants sentenced under Chapter 2L of the United States Sentencing Guidelines. Prior research has identified disparities in federal sentencing tied to race/ethnicity, citizenship status, and geographic context, but less attention has been given to how these factors are connected within immigration cases. The analysis uses individual-level case data for Fiscal Year (FY) 2024 from the United States Sentencing Commission, analyzing 14,354 noncitizen defendants sentenced for immigration-related offenses in federal courts across the contiguous United States. Sentence …

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 …

Despite its recognized value, limited research examines alumni engagement within graduate level programs from a practitioner perspective. The purpose of this study was to examine perceptions of alumni engagement among alumni, faculty, and staff within the University of South Florida (USF) Physician Assistant Program and to identify any needs or gaps in current engagement opportunities. This study employed a survey-based research design to gather data from two stakeholder groups from the USF PA Program: alumni and faculty/staff. A review of program records provided data …

Representations Of Motherhood In 19th And 20th Century American Literature, Zabrina L. Shkurti

USF Tampa Graduate Theses and Dissertations

This dissertation examines how American women writers of the 19th and early 20th centuries constructed, contested, and reimagined motherhood as both a lived experience and a powerful social institution. Drawing on feminist theory and motherhood studies—particularly Adrienne Rich’s distinction between motherhood as experience and motherhood as institution and Shari Thurer’s definition of the “good mother”—it argues that this institution and ideology were never stable or universally attainable. Instead, it functioned as a shifting, exclusionary construct shaped by race, class, industrial capitalism, and patriarchal authority. Through close readings of domestic literature, poetry, fiction, and reformist texts by writers including Elizabeth Oakes …

Human First: How Journalists Employ Ethics Of Care And Empathy When Covering School Shootings, Grace M. Ficara

USF Tampa Graduate Theses and Dissertations

Now, more than ever, journalists are needing to find innovative, yet empathetic, ways to deal with such crises as they navigate their own professional boundaries. Using the Ethics of Care model, this research intends to showcase how journalists have, willingly or unwillingly, utilized an empathetic approach when covering school shootings and how they use these tools to comfort their sources and themselves. Through semi - structured interviews of 9 participants, this study seeks to connect the practice of journalism with the one thing journalists …

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 …

Framing Power: The “Deep State” In Georgian Populist And Conspiratorial Rhetoric Introduction, Salome Tsetskhladze

USF Tampa Graduate Theses and Dissertations

This thesis investigates how the concept of the “deep state” is used in contemporary Georgian political communication. The term traditionally refers to hidden networks of power that function within state institutions. However, in Georgia, it has become a political narrative that interprets international criticism, delegitimizes domestic opposition, and derails political accountability. The study analyzes how this concept is constructed and mobilized in the political discourse.

The research employs a qualitative inductive-deductive thematic analysis. It examines 125 statements made by Georgian public officials between August 2024 and February 2025 referring to the “deep state.” The analysis integrates framing theory, populist communication …

Genetic Testing Motivations Among Men With A History Of Prostate Cancer: A Judgment-Based Analysis, Maximilian Junge

USF Tampa Graduate Theses and Dissertations

Identifying individuals at increased hereditary cancer risk through genetic testing can improve early detection, inform treatment decisions, and enhance outcomes for patients and their families. While prior research has largely focused on women, less is known about factors that motivate men with prostate cancer to pursue genetic testing. This study examined components of visual messaging that may influence motivation to undergo genetic testing among men with a self-reported history of prostate cancer. Participants completed a survey in which they viewed eight visual messages that systematically varied across three components: image type (family-focused vs. individualized treatment-focused), written content (familial risk-focused vs. …

Construction Of Chinese Identities And Community: A Linguistic Ethnographic Study Of A Chinese Culture-Sharing Club At A Us University, Yuxuan Mu

USF Tampa Graduate Theses and Dissertations

Chinese identity has been viewed as a debated and contested notion in sociolinguistics (Wong et al., 2021). Existing sociolinguistic research, which has centered on Chinese identity-related questions, such as “Who can be or cannot be Chinese?”, has been closely involved with the current political tensions between mainland China, Taiwan, and Hong Kong, as well as their associated linguistic tensions between simplified Chinese writing and traditional Chinese writing, and Cantonese and Mandarin. Building on these studies, this dissertation goes beyond the scope of Sinophone contexts traditionally examined in prior research (e.g., mainland China, Singapore, Taiwan, Hong Kong) to examine how US …

Dual-Modal Tumor Imaging Using Functionalized Iron-Oxide Nanoparticles For Mri And Fluorescence, Kevin Secades

USF Tampa Graduate Theses and Dissertations

Accurate tumor imaging is essential for early cancer detection and treatment monitoring [1]. Technetium-99m (Tc-99m) is a commonly used radioisotope for medical imaging, but its reliance on gamma-ray emission poses challenges related to safety, accessibility, and regulatory constraints[2-5]. This research proposes the development of a dual-modal imaging approach by functionalizing iron-oxide nanoparticles (IONPs) with the fluorescent chromophore Cy5, enabling both MRI contrast enhancement and optical imaging for improved tumor specificity. IONPs provide strong T2-weighted MRI contrast [6], while conjugated near-infrared (NIR) chromophores allow for high-resolution fluorescence imaging [7], making this proposed system adaptable for both in vitro and in vivo …

Analysis Of The Yeast Surface Display Platform As A Tool For Tyrosine Kinase Phosphorylation Assays, Alexandra Maritza Tang

USF Tampa Graduate Theses and Dissertations

Developing and optimizing platforms to study complex protein-protein interactions is important to maintain fidelity of the modeled activity. Yeast surface display has been used as a high-throughput platform to model substrate phosphorylation by tyrosine kinases, a key enzymatic process that is essential for most cell signaling pathways. However, existing characteristics of the yeast surface display platform limit the ease-of-use, reproducibility, and feasibility of screening enzymatic modification processes like tyrosine phosphorylation. The cytoplasmic domain of T cell costimulatory receptor CD28 and lymphocyte kinase (LCK) were used as a model enzyme-substrate pair to showcase molecular cloning issues that can hinder reproducibility and …
