A Life Course Approach To Understanding Preserved Cognition In Late Life, Cassidy E. Doyle

USF Tampa Graduate Theses and Dissertations

Some level of cognitive decline is generally expected with advanced age. However, a subgroup of individuals – commonly labeled as ‘SuperAgers’ – maintain youthful memory abilities into their 80s and beyond. Relatively little is known about factors across the life course related to this phenotype. This dissertation used population-based data from the Health and Retirement Study (HRS) to investigate lifestyle factors related to the most youthful cognitive trajectory in the United States and assess how their cognition fares over time. Three research questions were addressed: (1) Can samples of youthful cognitive agers be identified longitudinally in a population-based dataset? (2) …

Modeling The Pollution From Latrines In A Low- And Middle-Income Country Setting, Christopher Nenninger

USF Tampa Graduate Theses and Dissertations

Latrines are an important sanitation infrastructure that are critical to the United Nations’ effort to end open defecation and achieve the target regarding safely managed sanitation outlined in Sustainable Development Goal #6. This global effort has led to 40,000,000 new users being introduced to improved latrines each year, and this number is expected to increase as the world’s population grows. One of the drawbacks related to these new latrine additions is the potential increase in pollution from hydraulically connected latrine pits to shallow groundwater. This is especially problematic in low- and middle-income countries (LMICs), where communities are more likely to …

Fractional Calculus Approach For Learning Unknown Dynamic System, Haowei(Alice) Chen

USF Tampa Graduate Theses and Dissertations

The rapidly growing interest in data-driven modeling and fractional-order systems highlights a keychallenge in modern science and engineering: capturing long-memory effects and nonlinear behaviors in real-world dynamical processes. Conventional integer-order methods, while powerful, often overlook the history-dependent nature of many phenomena—ranging from viscoelastic materials to anomalous diffusion and hereditary feedback systems. This dissertation addresses that gap by blending fractional calculus with cutting-edge machine learning to create robust, memory-aware modeling and control frameworks.

Beginning with an extension of Dynamic Mode Decomposition (DMD) to fractional-order systems, we introduce Fractional Dynamic Mode Decomposition (F-DMD) as a data-driven tool that leverages Mittag- Leffler functions …

The Kinematics And Aerodynamics Of Freely Flying Tiny Insects, Evan J. Williams

USF Tampa Graduate Theses and Dissertations

Tiny insects are an extremely diverse set of organisms that have important engineering and economic applications. These organisms often fly and readily disperse distances that far exceed their body lengths. The mechanisms behind tiny insect flight are not well understood and present complex kinematics and unintuitive aerodynamics that depart from both fixed-winged mechanisms and larger insects. In addition, their tiny spatial and fast temporal scales make them exceedingly difficult to study, and to date, the field has relied on numerical studies and dynamic scaling. Herein, we describe three projects that significantly advanced our understanding of tiny insect flight and experimental …

Anhedonic Features In Effort-Related Reward Processing, Harold Alexander Rocha

USF Tampa Graduate Theses and Dissertations

Emerging evidence suggests that distinct stages of reward processing uniquely contribute to psychological traits linked to anhedonia, a core mood-disorder symptom characterized by diminished enjoyment of pleasure. However, the relationship between reward-processing stages and dispositional traits related to mood and anhedonia remains unclear. The present study investigated interindividual reward processing differences in a healthy college sample (n = 83) using self-report measures and event-related brain potentials (ERPs) indexing anticipatory and consummatory subprocesses across high- and low-effort conditions using a recently developed effort-doors task. The goal of the study was first to replicate the original ERP experimental effects of the task …

Trace Detection In Complex Gas Mixtures By Feedback-Assisted Multipass Raman Scattering, Jaspreet Singh

USF Tampa Graduate Theses and Dissertations

The recent development of Raman spectroscopy as a powerful analytical tool for trace gas analysis owes much to not only advancements in modern optoelectronic tools but also to substantial research in enhancement techniques. Feedback-assisted, non-resonant, multipass cavity Raman spectroscopy stands out among various Raman enhancement methods. We effectively employed this technique to estimate the deuterium/hydrogen ratio in water vapor, to simultaneously identify and quantify multiple analytes, even at extremely low concentrations such as 20 parts-per-billion for methane (CH4), and to detect hydrogen (H2) at concentrations as low as 75 parts-per-billion. This dissertation focuses on the practical application of spontaneous Raman …

“Smart Trap”: A Portable Device For Real-Time Mosquito Capturing And Classification Using Image-Based Analysis, Fahim Rahman

USF Tampa Graduate Theses and Dissertations

Capturing mosquitoes in real-time and taking high-quality images for classification with state-of-the-art methods is not only time-consuming but also expensive. Sometimes even carefully controlled environments and experimental setups fail to capture living mosquitoes. Catching live mosquitoes is necessary to be able to study aspects of their physiology and behavior that cannot be investigated by collections of resting mosquitoes and dead specimens, and to help estimate the local population numbers. My thesis introduces a “Smart Trap”, a small portable device that can attract mosquitoes in real-time, capture them, take high-quality images with dual cameras, and store those images in the cloud. …

Using A Descriptive Analysis And Functional Analysis To Determine The Topography Of Attention For Attention-Maintained Problem Behaviors, Sarah M. Loupe

USF Tampa Graduate Theses and Dissertations

This study examined the benefits of using descriptive analysis (DA)-informed functional analysis(FA) conditions to determine the functional relationship between problem behaviors and the topography of attention maintaining them. Three male participants completed the study, ranging in age from 7-12 years. Following indirect assessments with care providers, a DA was conducted during four 15-min observations. The results of the DA were used to calculate the probability of a specific topography of attention following a problem behavior P(SR/B) and the unconditional probability of a specific topography of attention in the absence of problem behavior divided by all occurrences of that topography UP(SR-B/SR). …

Vietnam Syndrome And The Genetic Consequences Of Agent Orange Poisoning: A Materialist Approach, Moriah M. Haley

USF Tampa Graduate Theses and Dissertations

The aim of this thesis was to propose and apply a materialist approach to “Vietnam Syndrome” found at the intersection of masculinity, disability, and state power as it manifests in modern military strategy. Through an analysis of the physical veteran body rendered infertile from Agent Orange poisoning during the Vietnam War, the material conditions of infertility are found to have threatened the hegemonic masculinity on which the military relied for its justification and continuation amongst young American men. The turn to technological warfare was intended to remedy the insufficiency of the military body, but the solution was costly and ineffective …

Protracting The Immediate: Time As Form In Contemporary Horror, Kennedy Kelley

USF Tampa Graduate Theses and Dissertations

This thesis examines the expression and experience of temporality in horror films of the last decade. Whereas early twenty-first century horror was characterized by high-octane jump scares, current horror is marked by contemplative slowness. I argue that the elongated duration of recent horror extends an experience of indeterminate anxiety that attunes us to an expansive relationality, offering a corrective not only to contemporary logics of immediacy, but also to the frequently constricting nature of embodiment as a theoretical concept. Recent horror scholarship tends to center sensuous propinquity in response to a long history of gaze theory’s disembodied passivity. While these …

Navigating Emotional Landscapes: A Black Woman's Perspectives, Nasya T. Jasper

USF Tampa Graduate Theses and Dissertations

Black women exist in a unique positionality and their experiences with depression and anxiety are shaped by distinctive structural factors. However, their experiences are often overlooked in sociological research and more broadly in academic/medical research. This study investigates the ways Black women are framing their experiences with depression and anxiety on Tiktok and Instagram. I conduct a qualitative study through a social media content analysis grounded in Black feminist thought and narrative analysis. This research is not only academic for me, but deeply personal, as I seek to amplify the voices of women whose struggles often go unrecognized. The findings …

Interviews with nine library workers from four densely populated counties in the U.S. state of Florida gave insight into the hypervisibility of inequality within and between public libraries, as well as the effects of this inequality on the libraries and their staff. The local changes that participants reported included population growth, constant development, gentrification, rising rents, and increased homelessness and affluence. Staff had diverse experiences …

The Manosphere’S Reception Of The Women Auteurs Behind The ‘Man-Eating’ Jennifer’S Body (2009) And ‘Man-Hating’ Barbie (2023), Hilda Sheridan-Hewlett

USF Tampa Graduate Theses and Dissertations

Scholarship on women filmmakers has not significantly emphasized the burden women auteurs carry when bracing themselves for the reception from misogynistic community discourse online, the manosphere. Director Greta Gerwig and screenwriter Diablo Cody are not simply perceived as filmmakers but as birth mothers of their work: Barbie (2023) and Jennifer’s Body (2009) which convey inherently popular feminist narratives. I argue Cody and Gerwig faced the wrath of the men online because they are inextricably linked to their productions, the feminization of their work in the eyes of the manosphere equals personalization. Despite Cody having the freedom to write any film …
