The Philosopher Of The Future: What Is It To Us That Herr Nietzsche Has Become Well Again?, Erli Mertika Apr 2026

The Philosopher Of The Future: What Is It To Us That Herr Nietzsche Has Become Well Again?, Erli Mertika

USF Tampa Graduate Theses and Dissertations

This dissertation argues that Nietzsche thought he was a genuine philosopher despite seeming at times to suggest that he was not. I arrive at this conclusion by comparing his thoughts on genuine philosophers with his thoughts about himself in an effort to show that his self-professed task is identical to theirs.

There are two types of genuine philosophers in Nietzsche’s late works: an old species that relied on a belief in “God” to legislate their values, and a new one that must do so without it. The former cannot perform their task after the death of God, which is why …


Theory And Applications Of Natural And Nature-Based Solutions In Estuarine Environments, Elizabeth L. Royer Apr 2026

Theory And Applications Of Natural And Nature-Based Solutions In Estuarine Environments, Elizabeth L. Royer

USF Tampa Graduate Theses and Dissertations

This dissertation focuses on the theory and application of Nature-based Solutions (NbS), through three unique case studies. This study explores how the broad and interdisciplinary NbS framework can be applied to mitigate common coastal hazards. This framework considers the environment, economics, and social wellbeing, equally in the design and implementation of a solution. The current paradigm, working against nature, which is commonly seen in more passive approaches to hazard mitigation, like grey infrastructure (e.g. a seawall to protect a shoreline against wave action) does not accommodate the extremely dynamic environment. As perspectives shift to “working with nature” NbS can be …


Sino-Indian Competition And Small-State Responses In The Western Indian Ocean: The Cases Of The Seychelles And Mauritius, Sidhyendra Sisodia, Manoj Kumar Mishra Apr 2026

Sino-Indian Competition And Small-State Responses In The Western Indian Ocean: The Cases Of The Seychelles And Mauritius, Sidhyendra Sisodia, Manoj Kumar Mishra

Journal of Strategic Security

The India-China rivalry, once concentrated on their contested land border, has now spilled decisively into the maritime domain, with both powers competing for influence in the Indian Ocean Region (IOR). Much of the existing literature focuses on Sri Lanka and the Maldives, leaving the Seychelles and Mauritius relatively underexplored. This article addresses that gap by examining how India and China have expanded their engagement with these small island states across security, infrastructure, and political domains. Drawing on defense cooperation, infrastructure projects, and contested basing proposals, it shows that both islands adopt selective hedging, albeit in different forms. Mauritius practices asymmetrical …


Post-Ukraine Fallout: How Azerbaijan’S Break With Russia Reflects The Strategic Consequences Of A Weakened Kremlin, Hasan Alisoy Apr 2026

Post-Ukraine Fallout: How Azerbaijan’S Break With Russia Reflects The Strategic Consequences Of A Weakened Kremlin, Hasan Alisoy

Journal of Strategic Security

This article analyzes how Russia’s declining power, accelerated by its military overextension in Ukraine, triggered a historic rupture in Russia–Azerbaijan relations, culminating in the 2025 Yekaterinburg incident. It argues that the deaths of two Azerbaijani citizens in Russian custody—and the retaliatory actions taken by Baku—did not cause the diplomatic collapse, but rather crystallized a long-term realignment rooted in Azerbaijan’s post-conflict assertiveness and Russia’s unraveling regional leverage. Drawing on the 2024 downing of an Azerbaijani airliner by a Russian missile, the premature withdrawal of Russian peacekeepers from Karabakh, and Azerbaijan’s evolving alliance with Türkiye, the article positions this realignment within a …


The Digital Radical: Online Extremism, Propagation, And Terror By Design's Strategic Implications For Homeland Security, Hunter Lacroix, Shevach Berkovits Apr 2026

The Digital Radical: Online Extremism, Propagation, And Terror By Design's Strategic Implications For Homeland Security, Hunter Lacroix, Shevach Berkovits

Journal of Strategic Security

The 'lone wolf' figure has long been central to counterterrorism analysis, representing the trajectory from non-participant to self-directed actor aligned with extremist causes. Traditional frameworks emphasizing in-person networks or online exposure, however, fail to capture the transformation of radicalization in the algorithmic age. The Arab Spring demonstrated the mobilizing power of digital platforms, yet movements like ISIS later weaponized these networks to provide ideology, belonging, and identity to dislocated populations. This article introduces the concept of the Digital Radical—an individual who transitions from passive consumer to active propagator of extremist narratives, sustaining and expanding radical ecosystems in a symbiotic …


Sheinbaum’S Dilemma: Mexico’S Security Choices After Fto Designation, Ghaleb Krame, John P. Sullivan, Magdalena Garcia Apr 2026

Sheinbaum’S Dilemma: Mexico’S Security Choices After Fto Designation, Ghaleb Krame, John P. Sullivan, Magdalena Garcia

Journal of Strategic Security

The US designation of six Mexican cartels as Foreign Terrorist Organizations (FTOs) marks a pivotal shift in bilateral security relations, compelling Mexico to navigate a complex strategic landscape. This study uses game-theoretic modeling, scenario analysis, and Nash equilibria to evaluate three possible responses by the administration of Claudia Sheinbaum: (1) Total Subordination—fully aligning with US counter-cartel efforts, (2) Covert Subordination—secretly integrating US support while maintaining a public stance of sovereignty, and (3) Strategic Resistance—rejecting US intervention in favor of an independent security approach.

New evidence on US-side border corruption and clearer definitions of key terms (joint cross-border operations, intelligence fusion …

Chemical Design Strategies For Hybrid Metal Halide Semiconductors With Enhanced Stability And Optoelectronic Properties, Ali Azmy Mar 2026

Chemical Design Strategies For Hybrid Metal Halide Semiconductors With Enhanced Stability And Optoelectronic Properties, Ali Azmy

USF Tampa Graduate Theses and Dissertations

Metal halide semiconductors have rejuvenated the attention of the scientific community for the last two decades owing to their photophysical and electronic properties. However, these materials have some limitations that hinder their commercialization and widespread application. One major limitation of these materials is their instability under ambient and operating conditions of moisture, head, light and radiation exposure. Here, we report multiple chemical design strategies to address the stability issues of these materials while simultaneously maintaining their exceptional optoelectronic properties. Such design strategies allowed the acquisition of the first members of the family of porous metal halide semiconductors which exhibit record …


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 Mar 2026

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, …


Temporally Modulated Acoustic Environment Alters Inferior Colliculus Tonotopy And Improves Neural Gap Encoding In Aged Cba/Caj Mice, Luis Franco-Waite Mar 2026

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 Mar 2026

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 Mar 2026

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 Mar 2026

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 Mar 2026

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), …


“Why Does My White Coat Feel So Tight?”: A Program Evaluation Of Well-Being Support For Physician Assistant Students, Danielle Castro Mar 2026

“Why Does My White Coat Feel So Tight?”: A Program Evaluation Of Well-Being Support For Physician Assistant Students, Danielle Castro

USF Tampa Graduate Theses and Dissertations

This dissertation presents a program evaluation of the Wellness Initiatives (WI) Program in the University of South Florida’s Physician Assistant (PA) Program, an accelerated 24-month graduate curriculum. The problem of practice is that PA students reported burnout, feeling overwhelmed, and difficulty navigating support within a year-round structure that did not consistently align with centralized university services. Guided by Theory of Change as the theoretical framework and Improvement Science as the conceptual framework, the evaluation examined how iterative wellness supports shaped students’ perceptions of well-being across six implementation cycles (May 2023–March 2025). A convergent parallel mixed methods design integrated survey data …


Secure Machine Learning In Networking Systems, Wenwei Zhao Mar 2026

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. …


The Molecular Determinants Of Deglycation And Substrate Specificity In Fructosamine Kinases, Jenet Matlack Mar 2026

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 …


Mathematics Anxiety: Understanding Its Concept, Impact On Secondary Students’ Academic Performance And Career Prospects, And Effective Intervention Strategies, Sabiruddin Molla, Safwana Rashid, Saba Sultana Mar 2026

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.


Housing Affordability Analysis Of Hillsborough County, Fl, Usa – Quantitative And Geographical Analysis Using Spatiotemporal Data, Bomin Koh Mar 2026

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 Mar 2026

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 Mar 2026

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 Mar 2026

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 …


Transport And Aging Pathways Of Microplastics In Urban Aquatic Systems, Jessica J. Boyer Mar 2026

Transport And Aging Pathways Of Microplastics In Urban Aquatic Systems, Jessica J. Boyer

USF Tampa Graduate Theses and Dissertations

Microplastics are pervasive in urban aquatic systems, which serve as both conduits of particle flow and incubators of microplastics. These aquatic systems transport microplastic particles while simultaneously altering their physical, chemical, and biological properties. Despite their growing environmental relevance, constructed wetlands and riverine systems remain underrepresented in studies of microplastic fate and transport. This dissertation aims to assess the patterns influencing microplastic transport and aging across urban aquatic environments through a combination of field experiments and mechanistic modeling.

Four interconnected studies were conducted to address this objective. The first investigated the horizontal and vertical transport of microplastics within the Se7en …
