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 …

Evidence-Based Telehealth Use In Ems: A Comprehensive Reference For Program Administrators, Field Leaders, And Clinical Directors, Michael Lozano Jr.

Florida Center for Emergency Medical Services Research Reports

Executive Summary

Telehealth-supported emergency medical services (EMS) represents an evidence-based approach to enhancing prehospital care delivery, expanding access to physician expertise, and improving resource utilization. This best-practice reference synthesizes current evidence and operational experience to guide EMS administrators in evaluating, implementing, and sustaining telehealth programs tailored to their communities' needs and resources.

Telehealth in EMS encompasses multiple distinct applications. General teleconsultation enables paramedics to connect with remote emergency physicians for real-time clinical guidance and disposition decisions. Specialty-specific applications focus on time-sensitive conditions including stroke and acute myocardial infarction, where early specialist involvement compresses treatment timelines. Community paramedicine integration extends EMS …

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 …

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 …

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 …

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 …

Examining Perceptions Of Minority Underrepresentation Among The United States Special Forces General Officers (O7-O10), Vincent X. Telfare

USF Tampa Graduate Theses and Dissertations

While the broader Department of Defense (DoD) has implemented important initiatives to advance equitable representation, the United States Army Special Forces (SF) has historically had a different distribution of diversity among General Officers (O7 to O10). This study explored the perceptions underlying this disparity through a qualitative narrative inquiry, using semi-structured interviews with selected retired SF officers of O6 and higher ranks. By examining participants' career experiences and perspectives on the Army's promotion system, this study seeks to illuminate the structural and cultural underpinnings that affect minority promotions to General and senior leadership positions in the Special Forces.

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, …

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. …

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.

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 …

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 …

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 …

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 …

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 …

Through semi - structured interviews of 9 participants, this study seeks to connect the practice of journalism with the one thing journalists …

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 …
