Integrated Sources Of Photon-Pairs For Quantum Networking, Vijay Soorya Shunmuga Sundaram

Theses

Quantum networking enables the distribution of quantum information across distant nodes, unlocking capabilities such as secure communication, distributed quantum computing, enhanced metrology, and tests of fundamental physics. Photons serve as the natural carriers of quantum information over long distances due to their low loss in optical fibers and robustness to environmental decoherence. However, the practical realization of quantum networks remains limited by the lack of photon sources that are simultaneously compatible with diverse quantum systems, stable over long timescales, and suitable for deployment in real-world fiber infrastructure.  This dissertation addresses these challenges through the co-development of photon-pair sources and a …

Disclosing Hunger: Predictors And Screening Strategies For Food Insecurity In Undergraduate University Students And Adults Contexts, Jocelyn Emily Jarvis

USF Tampa Graduate Theses and Dissertations

Food insecurity is a growing public health concern among college students in the United States, with prevalence estimates exceeding those of the general population. Despite the availability of campus, community, and federal food assistance resources, utilization remains low, suggesting that barriers extend beyond structural access. This dissertation examines the psychosocial, behavioral, and institutional factors that shape food insecurity disclosure and help-seeking behaviors among undergraduate students, guided by the Social Ecological Model (SEM).

This work includes three complementary studies. Study One presents a scoping review synthesizing 16 U.S.-based studies to identify psychosocial determinants of food assistance utilization among food-insecure adults. Findings …

Vestitus Auctoritate: Visual Representations Of Power In Late Roman Sicily, Angela L. Costello

USF Tampa Graduate Theses and Dissertations

This dissertation examines how Late Roman iconography of dress and appearance acted as visual bolsters of elite identity in the province of Sicily by engaging with two villas and their mosaic corpora: the Villa Romana del Casale, and the Villa Romana del Tellaro. Traditional Roman scholarship on power have focused on monuments, military achievements, and imperial building programs, and while these are all necessarily facets of Late Roman identity, there are valuable avenues left unexplored. Some, but not enough, attention has been given to the role of dress iconography during Late Antiquity. This study addresses this gap by investigating how …

Strategic Dimensions Of Artificial Intelligence: Development Globalization, Investment Dynamics, And Firm Performance, Alysson Silveira

USF Tampa Graduate Theses and Dissertations

Artificial Intelligence (AI) is quickly changing the competitive landscape of most industries, and understanding how to incorporate this technology into products, services, and processes is becoming crucial for firms. This dissertation presents three studies that address different strategic challenges that arose with the unfolding of AI. First, I study how multinational enterprises globalize the development of AI. I argue that concentrating AI development or globalizing it has different implications for supply chain responsiveness and operations complexity. I use a combination of a rare dataset on software presence across 45 countries and financial data to show that AI development globalization has …

Van Der Waals Interactions Through The Lens Of 2d Materials With Emphasis On Many-Body Effects, Thi Xuan Diem Dang

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the long-standing challenge of accurately and efficiently modeling long-range electron correlations, with a particular focus on van der Waals (vdW) interactions. These interactions play an essential role in predicting the structure, stability, and functionality of molecular systems and condensed matter materials. Although Density Functional Theory (DFT) has become a robust cornerstone of computational materials science, traditional formulations of the theory frequently fail to capture dispersive interactions, leading to significant errors in determining interlayer distances, binding energies, and stacking configurations. These limitations become particularly pronounced in layered materials and vdW heterostructures (HSTs), where weak long-range correlations are sensitive …

System Branding In Three Public Libraries: Live Oak Public Libraries, Charlotte Mecklenburg Library, And Richland Library, Patrick Roughen

Library Philosophy and Practice (e-journal)

This article examines library catalogs as brand artifacts in the context of two ancient libraries: the Library of Alexandria and the library of the Temple of Horus at Edfu, Egypt. Drawing on Pierre Bourdieu’s concept of symbolic capital and brand theory, this research argues that the catalogs of these two institutions functioned as early branding instruments. The Pinakes, the catalog of the Library of Alexandria, projected a brand of universal knowledge and intellectual prestige, and the inscribed wall catalog at Edfu reflected a brand focused on sacred authority and the sustaining of cosmic order (Ma'at).  Together, they illustrate two opposing …

An Unsolved Theft, Tim Pyatt

Library Philosophy and Practice (e-journal)

Using records preserved in the Duke University Archives and personal accounts, the author pieces together how the theft was discovered and the investigation was conducted. Potential suspects included the notorious thieves James Shinn and Stephen Blumberg as well as individuals identified during the investigation. The secrecy around the investigation as well as the effort to protect institutional reputation may have ultimately led to the theft never …

Rf-Derived Viscoelastic Modeling For Blood Clot Occlusion Sensing, Abdulrahman Mohammed Aldosari

Thesis/ Dissertation Defenses

Early and reliable detection of vascular thrombus remains a critical challenge for portable and non-invasive diagnostic systems. This work presents an RF-based sensing methodology for blood clot occlusion sensing through the extraction of viscoelastic clot characteristics derived from microwave reflection coefficient (S₁₁) measurements. A compact single-port coaxial probe is employed to interrogate the vessel–tissue system over a wide frequency range (1–25 GHz), where the measured RF response is used to derive equivalent viscoelastic and electrical model parameters associated with clot formation and progression. Both lumped-element RLC and distributed transmission-line representations are utilized to establish the relationship between the measured dielectric …

Disability Stigma, Disability Identity, And Psychological Distress Among Young Adults With Disabilities, Dylan G. Serpas

USF Tampa Graduate Theses and Dissertations

Disability discrimination is positively associated with psychological distress. Internalized disability stigma or the extent to which negative beliefs about one’s disability become personally adopted is implicated as a mediator. Moreover, disability identity processes, including identity affirmation and rejection may shape downstream consequences of navigating disability discrimination and internalization processes. These relationships are particularly relevant among young adults with disabilities (YAWD) who navigate a critical developmental period characterized by identity formation and heightened perception to social evaluation. In this study, 233 YAWD aged 18 to 25 completed a cross-sectional survey measuring disability microaggressions, internalized disability stigma, disability identity (rejection and affirmation), …

From Compliance To Regulation: Comparing Sensory And Behavioral Approaches For Elementary Students With Emotional Behavioral Disorders (Ebd), Morgan M. Lassila

Graduate Teacher Education

Traditional elementary classroom management often relied on top-down behavioral compliance models, which frequently proved insufficient when a student with an Emotional Behavioral Disorder (EBD) experienced physiological dysregulation. This systematic research synthesis examined literature from the past 15 years to evaluate how proactive, bottom-up, sensory-based interventions (SBIs) compared with traditional behavioral supports in reducing emotional dysregulation among public school elementary students (K-5). The findings indicated that the most effective methodology required a dual-approach framework. Integrating conventional behavioral tools, such as Positive Behavioral Interventions and Support (PBIS), with proactive sensory strategies effectively targeted the neurological roots of behavior. Furthermore, the literature demonstrated …

Findings revealed four major themes: systemic burden on parents, structural and service gaps, …

Respect And Aggression In Intimate Relationships: A Grounded Theory Of Relational Responsiveness, Aaron T. Fife

Theses and Dissertations

The negative effects of aggression in intimate relationships have been well documented through research and clinical literature (Lawrence & Bradbury, 2001; Shortt et al., 2006). Conversely, the positive effects of respectful behavior are well-known (Gottman, 1994; Dew & Wilcox, 2013). This important dimension of relationships is crucial to understanding what makes up healthy and unhealthy relationships. However, little is known about how couples understand the varying types of respect and aggression within intimate relationships, nor how they are lived and experienced relationally. The purpose of this study is to explore the dyadic processes behind respect and aggression as well as …

Toward Passwordless Document Encryption, Isaac Henry Teuscher

Theses and Dissertations

Document files with sensitive information are used across nearly every industry. In recent years, cyberattacks targeting cloud-based file transfer applications have resulted in millions of sensitive documents being exposed. Although document encryption methods exist, they are often limited in usability, security, or deployability. Password-based encryption, the most widely available option, remains vulnerable to brute-force attacks, unauthorized sharing, and human error. We address these gaps in three phases. First, we present a structured comparative framework adapted from the usability-deployability-security model to evaluate nine document encryption methods across 15 design properties, identifying the benefits and limitations of current approaches. Second, we design …

I Will Defend My Self, Emily Ward Hawkins

Theses and Dissertations

This thesis examines caregiving and motherhood as forms of load-bearing infrastructure. Cultural narratives often portray motherhood through sentimental images of joy, tenderness, and devotion, obscuring the structural labor that sustains family life. This project examines maternal labor as a largely unseen system of support that organizes family life while often remaining backgrounded. Caregiving reorganizes time, space, ambition, embodiment, and future orientation within maternal life. Through sculptural works using architectural materials and construction systems, such as oriented strand board, blueprint racks, metal armatures, and graph paper, the project visualizes caregiving as a structural condition. These materials reference the language of architecture …

We analyzed first-person experiences and perceptions about social confidence-building interventions and supports. We used pre- and post-group interviews of the adolescent autistic participants (n =11) and college-aged mentors (n = 4), pre- and post-group measures with the Social Responsiveness Scale, …

Beyond The Bell Curve: Understanding Native American Academic Placements, Sarah-Margaret Clark

Theses and Dissertations

This study examined biases regarding the referrals that teachers make regarding student placement recommendations for Native American students. Special education teachers (n = 97) from around the United States completed a digital card sort task involving 24 fictitious student record cards. The student record cards contained subtle information about the ethnicity of the student, as indicated through the use of racial identification (Native American, Asian, or White) on the student records and the use of student names that may be associated with these three categories. Academic information was equal among each of these three groups. Each group contained identical male …

Urban Indian Parents' Occupational Perceptions Of Play And Governance Of Children's Excessive Screen Time Preferences And Behaviours In This Digital Era, Joanna Priyadarshini Udaykumar, Tony Sam George

International Journal of Playwork Practice

Abstract

Children’s innate urge to engage in joyous, self-directed, meaningful, iterative activities embodies their unique play experiences and facilitates their holistic development. However, the exponential growth of digital technology in an urbanized world has transformed their social landscape by offering them a plethora of novel play opportunities that ‘pushes children away from the outdoors and pulls them indoors’. Moreover, the radical transition from nature-based recreation to media-centric activity insinuates the surge of a global pandemic characterized by low physical activity, sleep deprivation and sedentary, lifestyle diseases. This emerging trend reflects children’s predilection for videophilia over biophilia due to the dominance …

Institutional Influences And The Governance And Administration Of The Programa Produtor De Água Payment For Ecosystem Services Program In Brazil, Thomas G. Safford

Faculty Publications

Payment-for-Ecosystem-Services (PES) has been promoted as an innovative approach to environmental governance capable of simultaneously advancing conservation and sustainable development objectives. While studies commonly assess the ecological and economic performance of PES schemes, less attention has been given to their organizational and administrative effectiveness. This study examines these governance dimensions of one of Latin America’s most prominent PES initiatives—the Water Producer Program (WPP) in Brazil. Drawing on a meta-synthesis of 125 publications, the analysis investigates how regulative, normative, and cultural-cognitive institutional forces shaped WPP implementation. Guided by neo-institutional theory and institutional bricolage, findings show that WPP governance operated through hybrid …
