Evaluating The Effects Of Technology-Based Self-Monitoring And Contingency Mapping On The Disruptive Behavior Of Children With Autism Spectrum Disorder, Alexandra R. Pruitt

USF Tampa Graduate Theses and Dissertations

Self-monitoring (SM) is an evidence-based self-management procedure that can improve behavior and academic performance across diverse populations and settings. However, results of a meta-analysis of SM on strategy use and academic performance of K-12 and higher education students suggest that SM is more effective when it is embedded into a multi-component intervention. Contingency mapping (CM), a visual representation of contingencies in effect for desirable and undesirable behaviors, has been shown to improve behavior (e.g., increase social communication skills, increase on-task behavior) in the clinical and school settings. Previous research has not evaluated the effects of a treatment package consisting of …

Impostor Syndrome In The Ranks: Understanding Self-Doubt To Improve Leader Performance, Joel Kotanko

USF Tampa Graduate Theses and Dissertations

Impostor syndrome (IS) — the persistent pattern of self-doubt in which capable individuals fear being exposed as frauds despite objective evidence of competence — has been studied extensively in academic, healthcare, and corporate populations, where it is generally treated as detrimental to professional performance. Little empirical work has examined IS in U.S. military officers, a population operating under structural conditions the literature identifies as primary amplifiers of fraudulence perceptions: high-stakes permanent evaluations, up-or-out promotion systems, cultural pressure against outward expressions of doubt, and recurring role transitions under compressed timelines. This dissertation provides the first quantitative investigation of the relationship between …

Engineering Fsh-Cer T Cells To Enhance Response To Epithelial Ovarian Cancer, Nolan J. Beatty

USF Tampa Graduate Theses and Dissertations

Ovarian cancer remains a significant cause of cancer-related mortality, with epithelial ovarian cancer (EOC) being the most common subtype. Despite advances in treatment, the 5-year survival rate for late-stage EOC remains low due to factors such as tumor heterogeneity and an immunosuppressive tumor microenvironment (TME). This study investigates the therapeutic potential of chimeric endocrine receptor (CER) T cells engineered to express follicle stimulating hormone (FSH) in a syngeneic mouse model of EOC expressing follicle stimulating hormone receptor (ID8-FSHR). We compared two different co-stimulatory domains—CD28ζ and 4-1BBζ—in FSH-CER T cells and found that FSH-CD28ζ CER T cells exhibited enhanced cytotoxicity, proliferation, …

Nanoscale Morphological Perturbations Of Lipid Membranes Induced By Membrane Active Peptides, Yasith Sandeepa Indigahawela Gamage

USF Tampa Graduate Theses and Dissertations

Membrane-active peptides (MAPs) are a diverse group of biologically relevant molecules that induce nanoscale modulations during their interactions with cell membranes. Understanding the precise mechanism by which these MAPs perturb or modulate the cell membranes is a cornerstone of membrane biophysics, as it facilitates rational design of useful therapeutics. That is, if we have the knowledge to determine what the peptide can do, how selective it is, or how toxic it might be, we can optimize them and design new peptide therapeutics such as for antimicrobial, anticancer, or drug-delivery applications. In general, MAPs can be categorized into two classes based …

Subspace Decomposition For Spatial Parameter Estimation, Arthur Grik

USF Tampa Graduate Theses and Dissertations

Passive emitter localization is an important capability for wireless sensing, interference detection, and spectrum awareness. Classical timing-based localization methods estimate emitter position from differences in signal arrival time across distributed sensor platforms, but their performance depends on precise receiver synchronization and favorable signal bandwidth characteristics. This thesis investigates subspace-decomposition-based spatial parameter estimation as an alternative approach in which directional information is extracted from coherent antenna-array measurements. This work develops the theoretical foundation and signal-processing framework for angle-of-arrival estimation. Various spatial parameter estimators are presented as supporting array-processing methods before focusing on a well-known subspace-decomposition-based approach called the Multiple SIgnal Classification …

Skill Acquisition: Evaluation Of Instructional Procedures, Ellen I. Ratliff

USF Tampa Graduate Theses and Dissertations

Identifying effective and efficient interventions is essential for establishing independent responding in learners with autism spectrum disorder and related developmental disabilities. The present study replicated and extended Gorgan and Kodak (2019) by comparing differential reinforcement, most-to-least prompt fading, and extended response interval procedures for teaching novel skills to three children with autism spectrum disorder who did not demonstrate prompt-dependent responding. Using an adapted alternating treatments design, each intervention was evaluated against a control condition with an equated opportunity interval. Extensions to prior research included conducting a reinforcer assessment to verify differentiation in stimulus potency, modifying the controlling prompt assessment to …

Examining The Impact Of A Positive Psychology Service-Learning Experience On Undergraduates’ Mental Health And Career Intentions, Cydney E. Williams

USF Tampa Graduate Theses and Dissertations

Universities currently face a growing public health concern regarding college students’ mental health and well-being (Hobbs et al., 2022; Sheldon et al., 2021). Given this, research has explored experiences that are advantageous for students’ overall well-being, including courses on positive psychology and service-learning experiences that may promote flourishing (Hobbs et al., 2022; Maples et al., 2022). Service-learning is also well situated to support undergraduate career development (Collison & Eck, 2022). Kranzler et al. (2011) described how the pedagogical approach of service-learning aligns well with positive psychology, leading them to implement a positive psychology service-learning course. However, to date, no study …

"Does The Penis Lie?": Truth, Sexuality, And Psychocarceral Power, Erin Mcqueary

USF Tampa Graduate Theses and Dissertations

This thesis critically examines the use of penile plethysmography (PPG), or phallometry, in the treatment and management of sex offenders in the late-twentieth century. Using the Florida Mental Health Institute’s 1986-1989 sex offender treatment program as a case study, it asks how phallometry came to be understood as an objective method for uncovering otherwise hidden sexual truths. Instead of focusing only on its appearance and development throughout the second half of the twentieth century, this thesis draws on the work of Michel Foucault to situate phallometric science within a broader history of sexuality and biopower. In doing so, it argues …

Exploring Staphylococcus Aureus Host-Pathogen Interaction Using Proteomic Technologies, Emilee Marlene Elizabeth Mustor

USF Tampa Graduate Theses and Dissertations

Staphylococcus aureus deploys an arsenal of virulence effectors to remodel the host environment during infection, while simultaneously the host mounts an immune response to contain and eliminate this bacterium. This dynamic interplay defines the host-pathogen interface and shapes infection outcome. In this context, the secreted proteases represent a major arm of S. aureus pathogenesis, promoting bacterial persistence in the host by dismantling immune defenses, cleaving host signaling molecules and reshaping the host proteome. However, traditional substrate-by-substrate characterization cannot reveal the full scope of proteolytic activity occurring during infection. To address this, we developed Terminal Amine-Guanidination of Substrates-Charge Reversal (TAGS-CR), a …

Trauma-Informed Care In Residential Settings: Staff Perceptions And The Impact Of The Prevent-Teach-Reinforce Model With Trauma-Informed Principles, Marissa L. Del Vecchio

USF Tampa Graduate Theses and Dissertations

Trauma-informed care (TIC) has been recognized as a critical framework for supporting individuals on the autism spectrum, intellectual and developmental disabilities (I/DD) and those within residential facilities given their heightened risk for experiencing adverse events, including trauma. However, the development and evaluation of a trauma-informed behavior analytic assessment and intervention approach is lacking. Although behavior analysts frequently target behaviors associated with trauma, research suggests that many practitioners have limited training, supervision and competence in TIC, despite widespread recognition of its importance. The Prevent-Teach-Reinforce (PTR) model may be a promising approach to address these limitations, as its practices align closely with …

Multi-Modal Survival Prediction On Breast Cancer Mammograms And Enabling Multi-Institutional Collaborations With Federated Learning, Nikolas Koutsoubis

USF Tampa Graduate Theses and Dissertations

Cancer remains one of the leading causes of mortality worldwide, and machine learning is well positioned to leverage the large volumes of routinely collected clinical and imaging data to improve patient outcomes. Realizing this potential at scale requires three capabilities that current practice does not yet deliver in combination: models that integrate the multiple data modalities clinicians use, training procedures that respect institutional data-sharing constraints, and tooling that enables sharing of de-identified data when federated approaches are not sufficient. This dissertation develops methods and infrastructure addressing each of these capabilities in the context of breast cancer and oncology more broadly. …

Testimonios From Latine Educational Leaders Supporting Youth Development Programs, Luis E. Feliciano

USF Tampa Graduate Theses and Dissertations

The United States has been experiencing a demographic change for the last twenty years representing a rise in both Latiné students and families. Despite this demographic change, Latiné folk remain widely underrepresented in school leadership, and furthermore underrepresented in specific Youth Development Programs (YDPs), with the relationship between educational leaders and YDPs being widely unexplored in academia. This study sought to bridge the gap between YDPs and educational leadership, specifically for Latiné folk by asking how Latiné educational leaders used their cultural heritage to encourage YDP development. To accomplish this a testimonio methodology was implemented via a two staged interview …

USF Tampa Graduate Theses and Dissertations

Pediatric cancer survivors are at increased risk for obesity and related long-term health complications, highlighting the need for interventions promoting healthy lifestyle behaviors during survivorship. The present study examined caregivers’ fruit and vegetable intake in the full NOURISH-T+ intervention and evaluated whether their dietary outcomes changed from baseline to the 3-month post-assessment and differed by selected caregiver sociodemographic characteristics. The study also examined whether these characteristics accounted for variance in 3-month fruit and vegetable outcomes. Participants included 68 caregivers in the full NOURISH-T+ condition who completed both baseline and 3-month post-assessments. Fruit and vegetable intake was assessed using the Healthy …

Interpreting Discrepant Multi-Informant Data: Examining School Psychologists’ Decision-Making Processes With Social-Emotional And Behavioral Assessment, Thomas Koza

USF Tampa Graduate Theses and Dissertations

Multi-informant assessment is a common method used by school psychologists to collect data on students' social-emotional and behavioral concerns across the three tiers of the Multi-Tiered System of Supports (MTSS) framework. While this data can provide a comprehensive understanding of student functioning, informant discrepancies are common, and little is known about how school psychologists make sense of discrepant data or whether using structured frameworks can support their interpretation. This dissertation used an experimental mixed-methods design with vignettes to examine how school psychologists interpret discrepant multi-informant social-emotional and behavioral assessment data and whether exposure to a structured framework influenced this process. …

Intersectional Inequities In End-Of-Life Care Quality: The Roles Of Race, Ethnicity, And Gender, Jessica A. Yauk

USF Tampa Graduate Theses and Dissertations

Persistent gaps remain in end-of-life care quality (EOLCQ) in the United States. Structural factors within the health care system, as well as discriminatory practices, affect the quality of care received by at-risk populations. This dissertation uses a mixed-methods research design to examine perceived EOLCQ across racial/ethnic and gender groups. Study 1 and Study 2 were guided by the intersectionality and Social Determinants of Health (SDOH) frameworks, and examined ten EOLCQ outcomes: pain, dyspnea, sadness or anxiety, having personal care needs met, having decisions made about care without enough input from decedent or family, whether the proxy or family were kept …

USF Tampa Graduate Theses and Dissertations

The rapid advancement of wireless networks has enabled a wide range of applications such as federated learning (FL) and Internet of Things, with supporting technologies like radio frequency identification (RFID). However, resource management and security challenges in wireless networks remain insufficiently addressed for these representative applications. In this dissertation, we first investigate wireless resource management for FL, then study novel attack and defense mechanisms for RFID systems. Finally, we analyze the performance and security of artificial intelligence (AI)-enabled next generation wireless networks.

First, we investigate the client assignment and bandwidth allocation problem for FL in a multi-provider wireless setting. Unlike …

Building Trustworthy Information Systems: A Unified Framework For Comparative Risk Detection, Parisa Momeni

USF Tampa Graduate Theses and Dissertations

Risk detection in large scale information systems increasingly depends on heterogeneous data generatedby both centralized and distributed ecosystems. While centralized systems provide curated and validated reports, distributed environments produce large-scale and real-time observational evidence. Existing computational approaches analyze these ecosystems in isolation, limiting systematic comparison of risk repre-sentations across heterogeneous sources.

This dissertation presents a unified computational framework for comparative risk detection across centralized and distributed information systems. The framework provides a domain independent methodology for transforming heterogeneous risk reporting data into comparable multidimensional representations. To enable interpretable comparison of heterogeneous risk distributions, this work introduces the Geometric Overlap Score …

Aligning Perspectives: Exploring Parent-Youth Agreement On Well-Being And The Impact Of Positive Psychology On Communication & Relationship Habits, Daijah N. Hines

USF Tampa Graduate Theses and Dissertations

As research calls for best practices in assessment of psychological constructs from multiple informants, more information is needed for secondary reports of subjective experiences such as perceptions of life satisfaction. Adolescence is a vital period for intervention and assessment supports to promote well-being, yet there is a gap in the research on how to interpret multi-informant data for mental health constructs such as subjective well-being especially within this population. Research has shown support for and validated the use of parents/caregivers as secondary informants (Dew & Huebner, 1994; Hines et al., 2023; Shoshani & Slone, 2017) yet there is still vague …

Association Of Social Isolation, Loneliness, Social Strain And Support With Cancer Onset, And Frailty And All-Cause Mortality In People With Cancer, Joanne Elayoubi

USF Tampa Graduate Theses and Dissertations

Cancer is the second leading cause of death both in the United States and globally and for individuals over sixty-five. In 2026, approximately 2,114,850 new cancer cases are projected to emerge according to the National Center for Health Statistics (Siegel et al., 2026). Cancer incidence is increasing, making older adults sixty-five and older at risk of frailty and mortality following cancer. Although social isolation, loneliness, lack of social support, and social strain have been found to be risk factors for poor health and mortality, it is not clear the extent to which social relationships are associated with incident cancer, and …

Hospitality As A Languageless Movement: Mapping The Interconnectedness Of Inclusion, Disability, And Hospitality, Alycia M. Bobak

USF Tampa Graduate Theses and Dissertations

This dissertation thinks with post-qualitative inquiry to explore how inclusion, disability, and hospitality move through spaces in higher education and how their meanings shift between policy, practice, and personal ethics and dispositions. Using Derrida’s notion of hospitality and Deleuze and Guattari’s concept of the Body without Organs, this study presents the consideration of how university spaces welcome students with disabilities and how feelings of belonging, receiving, and acceptance are produced within those spaces. Rather than viewing inclusion and disability as fixed concepts, this research considers how language and personal ethics continuously reshape their meaning through interactions and affect.

This study …

Using Contingency Mapping To Decrease Disruptive Behavior And Increase On-Task Behavior For Students With Autism Spectrum Disorder, Carelis Y. Pabey Pagan

USF Tampa Graduate Theses and Dissertations

Visual aids have been widely used in educational and therapeutic settings to support individuals with developmental disabilities, particularly autism spectrum disorder (ASD). Among these, contingency maps, a graphic tool that visually represents the outcomes of alternative behaviors and problem behavior, have shown promise in reducing problem behavior, increasing communication, and promoting independence. However, existing research on contingency mapping is limited. The proposed study extended this literature by evaluating the effects of contingency maps on academic engagement and disruptive behavior for children with ASD in a school setting during natural classroom activities. A multiple baseline design across participants was used to …

Philanthropic Grantmakers’ Roles In Transforming Higher Education: A Narrative Inquiry, Elizabeth Jean Larkin Davis

USF Tampa Graduate Theses and Dissertations

Philanthropic foundations have become influential actors in higher education reform, often supporting initiatives to improve student success, advance equity, and promote systemic change. Yet limited research has examined how philanthropic grantmakers understand and navigate their roles in shaping long-term change across the higher education field. This narrative inquiry explored the personal and professional experiences of eight philanthropic grantmakers working across different foundations, roles, and organizational contexts in the United States. Guided by organizational change theory, Strategic Action Fields theory, and sustainability planning in dynamic systems, the study examined how grantmakers made sense of their responsibilities, influence, and contributions to systemic …

Examining The Referral Pathway For Black Families Evaluated Through The Early Steps Program, Zelda Fleming

USF Tampa Graduate Theses and Dissertations

Research indicates that for children with or at risk for developmental delays, early intervention services are associated with improvements in academic and cognitive skills by the time they reach kindergarten (Atkins et al., 2020; Litt et al., 2017). Untreated developmental delays are linked to early school failure and social and emotional problems (Sher et al., 2020). Black children are 5 times less likely to receive early intervention services when compared to their White peers (Barnard-Brak et al., 2021; Feinberg et al.,2011). Thus, they often do not have the opportunity to receive early intervention services. The literature in this area suggests …

Designing For Fitness And Resilience In Human Artificial Intelligence Systems, Thomas R. Gill

USF Tampa Graduate Theses and Dissertations

Over the last decade, new artificial intelligence models, frameworks, and applications have emerged that have radically changed the socio-technical landscape. These new technologies represent both great opportunities and great potential risks. Due to the recency of their emergence, there is little known about the longevity and long-term repercussions of artifacts powered by new artificial intelligence technology. In this dissertation, I evaluate A.I. and A.I.-based artifacts through the lens of the fitness-utility model, a tool developed by Gill and Hevner (2013) for the evaluation of an artifact's ability to survive and reproduce over long time horizons. In so doing, I also …

Photoluminescent Studies Of Metal-Organic Frameworks For Small Molecule Sensing, Julia T. Dematteo

USF Tampa Graduate Theses and Dissertations

Metal–organic frameworks (MOFs) are highly tunable nanoporous materials with broad applications in gas separation, drug delivery, light harvesting, and chemical sensing. The incorporation of photoactive components into MOFs enables the development of optical sensors capable of detecting a wide range of analytes. Porphyrins and metalloporphyrins are particularly attractive for such applications due to their high molar absorptivity, strong emission quantum yields, and versatile interactions with chemical species.

In this work, two porphyrinic MOFs, PCN-222 and MOF1(Cd), are investigated. Both frameworks utilize tetrakis(4-carboxyphenyl)porphyrin (TCPP) as the organic linker, imparting optical functionality to the materials. Integration of TCPP into the framework induces …

Development And Initial Validation Of The Identifying Behavioral And Emotional Growth Indicators And Needs—Parent Rating (I-Begin-P), Samin Khallaghi

USF Tampa Graduate Theses and Dissertations

Multi-informant approaches provide a more comprehensive understanding of behavior patterns and are considered the gold standard for behavioral assessment. However, few screening tools for young children in school settings incorporate parental perspectives, and those that do remain under-researched with respect to their validity and reliability. To address these gaps, the Identifying Behavioral and Emotional Growth Indicators and Needs-Parent Form (I-BEGIN-P) was developed as an extension of the I-BEGIN-T (Teacher) scale for children aged 3 to 5 years. The purpose of this study was to develop and initially validate I-BEGIN-P. First, the content validity of I-BEGIN-P was assessed using expert panel …
