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 …

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 …

Subsistence And Settlement In Northwest Florida During The Late Archaic-Early Woodland Transition (3500 Bc Through Ad 300), Kerri A. Klein

USF Tampa Graduate Theses and Dissertations

This research presents quantitative and qualitative data on subsistence and cultural transitions in a warm-temperate area of northwest Florida during the Late Archaic-Early Woodland transition (from about 3500 – AD 300). By completing an inventory of the faunal assemblages from two shell middens, I was able to evaluate resource selection and use both within and between sites. Results suggest that site inhabitants utilized consistent resources, despite any documented or potential climatic and ecological change which occurred. Radiocarbon dating establishes the timelines for both Sam’s Creek Cutoff (8FR754), a single-component Late Archaic campsite, and Depot Creek (8GU56), which has a Late …

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 …

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 …

In this dissertation, I present my research on enhancing the security and efficiency of networked systems through measurement-driven vulnerability analysis and the design of scalable defense mechanisms.

First, I present my research on the security and privacy risks of Wi-Fi–based localization services. Although location spoofing attacks against Wi-Fi positioning systems have been studied for over a decade, constructing practical attacks in …

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 …

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 …

Spin Pumping And Interfacial Anisotropy In Ultrathin Cobalt Heterostructures, Ibrahim Almuhanna

USF Tampa Graduate Theses and Dissertations

Interfaces dominate the behavior of ultrathin ferromagnets, where interfacial spin-orbit coupling(SOC) can strongly influence both magnetic anisotropy and magnetization dynamics. This thesis compares how a heavy-metal interface (Pt) and a semiconducting two-dimensional transition-metal dichalcogenide (TMD) interface (MoSe2) modify the static and dynamic magnetic properties of ultrathin Co. To isolate interface-driven effects, the heterostructure architecture is kept fixed (sapphire substrate and Si3N4 cap) while only the seeding/interface layer beneath Co is varied. MoSe2 is studied in two thickness conditions (monolayer and bilayer) to test layer-dependent trends.

Layer thicknesses are determined by X-ray reflectivity. Static magnetic properties are measured by in-plane vibrating …

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 …

Examining The Effect Of Household Socioeconomic Status And Maternal Characteristics On Child Developmental Delay In The United States, Samuel Ilori

USF Tampa Graduate Theses and Dissertations

Child developmental delay remains a pressing public health issue with lifelong implications. This study examines the association between household socioeconomic status, maternal characteristics, and child developmental delay using data from the 2023 National Survey of Children's Health (N = 35,399 female respondents). Bivariate analyses using Chi-square tests and binary logistic regression with sequential modeling were conducted. Results revealed that economic hardship, employment status, maternal mental health, maternal physical health, marital status, and race were significantly associated with child developmental delay (p<0.001). Educational level and poverty level showed no significant associations. Among mothers reporting poor mental health, 90.0% had a child with a delay, compared to 6.6% among those with good mental health. Every mother reporting poor physical health had a child with a delay, while virtually none with good or better physical health did. In the fully adjusted regression model, maternal mental and physical health remained the most powerful predictors, while economic hardship and employment status became non-significant once health was introduced, suggesting mediation. Maternal mental and physical health are the factors most strongly correlated with child developmental delay. Economic hardship matters primarily because it undermines maternal well-being. The COVID-19 pandemic likely intensified these dynamics by disrupting healthcare access and increasing economic instability. Supporting maternal health must be recognized as a fundamental strategy for promoting child development. Universal screening for maternal depression and physical health problems, integrated into pediatric and obstetric care, can identify at-risk mothers early. Policies that reduce economic hardship alleviate the chronic stress that undermines maternal health. Children thrive when their mothers are healthy.

The Development And Validation Of A Portable Monitoring System For Real-World Prosthetic And Orthotic Performance Assessment, Emily Wyatt

USF Tampa Graduate Theses and Dissertations

Laboratory-based motion capture systems are widely used for gait analysis but are limited by high cost, infrastructure requirements, and restricted external validity. Inertial measurement units (IMUs) offer a portable and low-cost alternative for assessing gait in both controlled and real-world environments; however, their accuracy and clinical utility require validation. The purpose of this thesis was to develop and evaluate a portable monitoring system using IMUs to quantify spatiotemporal gait parameters and gait asymmetry in both laboratory and community settings, with a focus on prosthetic and orthotic users.

Phase 1 of this study evaluated the agreement between IMU-derived gait metrics and …

The Role Of Teacher-Student Identity-Matching In Multi-Informant Universal Screening For Social, Academic, And Emotional Behavior Risk Among Middle School Students, Melissa L. Brown

USF Tampa Graduate Theses and Dissertations

Multi-informant universal screening tools leverage insights from multiple perspectives to paint a comprehensive picture of student risk across a variety of domains. However, many barriers exist to the appropriate and effective implementation of multi-informant universal screening within the school. When such screening tools are utilized without intentional consideration of students’ unique backgrounds and lived experiences, harmful outcomes may disproportionally impact marginalized and minoritized students. To address this, context-sensitive, identity-conscious approaches may improve the accuracy and equity of identifying students in need of support. This study investigated the role of identity concordance (i.e., alignment of teacher and student gender and race/ethnicity) …

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. …

Assessing Capability, Opportunity, And Motivation In Relation To Guideline Adherence For Inherited Cancer Risk, Cecilia L. Delisanti

USF Tampa Graduate Theses and Dissertations

Introduction: Although National Comprehensive Cancer Network (NCCN) guidelines provide cancer screening or risk reduction recommendations for individuals with germline pathogenic and likely pathogenic variants (GPVs) in actionable hereditary cancer genes, guideline adherence remains inconsistent, and the behavioral contributors to this gap remain understudied. To identify behavioral factors related to adherence across inherited cancer risk genes, this study used the COM-B model, which posits that capability, opportunity, and motivation shape health behaviors.

Methods: IMPACT study participants, all with GPVs in a variety of actionable genes, completed surveys (N=575). Minimal adherence was based on gene-specific NCCN guidelines. COM-B constructs (capability, opportunity, motivation) …

The Emotional Construction Of Religious Experience: Senitmentalism And Moral Motivations, Yvonne Candelario

USF Tampa Graduate Theses and Dissertations

This paper addresses the growing prevalence of reported religious experiences across diverse religious and spiritual traditions, alongside the persistent absence of such reports among many adherents within the same communities. This asymmetry poses a challenge for both supernaturalist and reductively skeptical accounts of religious experience. I develop a naturalistic constructivist framework to explain why some individuals choose to interpret and report some human experiences as religious experiences or report having religious experiences at all, while others do not. Drawing on a post-modern revision of moral theory, an account of constructive sentimentalism, I argue that religious experience is shaped by socially …

Analysing Numeracy Demands In Alberta Curriculum: A Focus On High School Mathematics, Asia Majeed, Kwesi Yaro

Numeracy

In recent years, numeracy has been recognized as a key educational priority across the curriculum in many international jurisdictions, including almost all Canadian provinces. In Alberta province, Canada, for example, the Teaching Quality Standard (TQS) #3 explicitly states that all teachers are responsible for fostering literacy and numeracy skills, regardless of the specific subject areas they teach. This expanded focus reflects a broader understanding of numeracy not merely as a subset of mathematical skills, but as a fundamental competency that supports informed participation in civic, economic, and personal life. This paper applies the 21st Century Numeracy Model (Goos et al., …

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 …

Everyone Works On The Sustainability Team: Power Structures And Brand Communication In Sustainable Consumption, Sofia Johansson

USF Tampa Graduate Theses and Dissertations

In response to growing concerns about the way in which consumption practices negatively degrade the environment and contribute to climate change, this thesis explores the role in which brands may counteract this. There are two significant issues pertaining to environmental marketing: (1) current efforts to promote green consumerism, through which consumer brands market products as “eco-friendly” with only marginal reductions in climate impact and misleading labels, are insufficient in mitigating climate change. (2) Additionally, this kind of consumption is unjust, whereby it is marked up in price, limiting access to merely individuals in higher income brackets. Given the insufficiencies of …

A Unified Non-Visual Explainable Ai Framework For Neonatal Pain Assessment, Md Imran Hossain

USF Tampa Graduate Theses and Dissertations

With the power of parallel processing, large datasets, and fast computational resources,deep neural networks (DNNs) have outperformed highly trained and experienced human experts in medical applications. However, the large global community of healthcare professionals, many of whom routinely face potentially life-or-death outcomes with complex medicolegal consequences, have yet to embrace this powerful technology. The major problem is that most current AI solutions function as a metaphorical black-box positioned between input data and output decisions without a rigorous explanation for their internal processes. With the goal of enhancing trust and improving acceptance of artificial intelligence– (AI) based technology in clinical medicine, …

Impact Of Statin Medication Use On Glycemic Control And Complications In Type 1 Diabetes, Ryan Bailey

USF Tampa Graduate Theses and Dissertations

Introduction: Hydroxymethylglutaryl-CoA enzyme inhibitors (statins) are frequently used to prevent cardiovascular events in individuals at high risk for cardiovascular diseases, including individuals with diabetes. Prior research has indicated that statins may increase the risk of developing type 2 diabetes (T2D) and may increase hyperglycemia among those previously diagnosed with T2D. To date, little research has investigated the impact of statins on glycemic control and diabetic complications associated with poor glycemic control in those with type 1 diabetes (T1D). The objective of this dissertation is to investigate the association between statin use and measures of glycemic control including hemoglobin A1c (HbA1c), …

Examining Whether Survivors Of Domestic Violence Perceive Ifps As More Helpful Than Other Available Support Resources, Aleidys Lopez Romero

USF Tampa Graduate Theses and Dissertations

Injunctions for protection (also known as restraining orders or civil protection orders) are often used by survivors as a line of defense against continued instances of physical violence or stalking by abusers (Houseman et al., 2024). This study aims to fill these gaps by examining whether survivors of domestic violence perceive IFPs as more helpful than other available support resources. Understanding this process may offer important insights into IFP accessibility, survivor perspectives, and/or alternative resources that may be equally, if not more, helpful to survivors than IFPs. Grounded in Gondolf & Fisher’s (1988) Survivor Hypothesis and Kimberlé Crenshaw’s (1989) Structural …
