Improving Cancer Diagnosis And Patient Outcomes With Deep Learning Models, Mariana Arriz-Jorquiera

USF Tampa Graduate Theses and Dissertations

Cancer care depends on timely and reliable decisions, from detection and diagnosis to treatment planning and patient monitoring. These decisions are often made under uncertainty because medical images and healthcare data may be noisy, incomplete, or difficult to interpret. In breast cancer imaging, ultrasound is widely used because it is safe, accessible, and complementary to other imaging modalities. However, variations in image quality, acquisition conditions, and noise can obscure lesion boundaries and texture, affecting human interpretation and artificial intelligence reliability. This dissertation develops deep learning, image-analysis, and optimization methods to improve healthcare decisions under imperfect information. Its primary focus is …

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 …

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 …

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 …

Evaluating The Role Of Individual Differences: Impact On Fruit And Vegetable Intake Outcomes In Nourish-T+ Caregivers Of Pediatric Cancer Survivors, Sandra Soca Lozano

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 …

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 …

Race, Ethnic, And Gender Disparities In Human Trafficking Risk, Identification, And Investigation, Emily D. Walker

USF Tampa Graduate Theses and Dissertations

Youth and human trafficking remain significant and complex issues. Existing literature suggests that trafficking risk, victimization, and identification are shaped by structural and social context, creating differential impacts across demographic groups, such as racial, ethnic, and gendered groups. Yet, current research has yet to fully capture the complexity of victimization across groups. This dissertation consists of three interconnected studies examining youth trafficking investigations. Using a mixed-methods approach and administrative data from Florida Department of Children and Families (DCF), this dissertation address three objectives (1) examining potential variation in documentation of trafficking risk, victimization, and narrative framing of youth trafficking investigations …

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 …

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 …

Man Down: Exploring Identity, Uncertainty And Resilience In An Autoethnographic Performance Of Prostate Cancer As Applied Health Communication, Kevin Hawley

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation study was to explore how an autoethnographic performance of my experience of prostate cancer could serve as a method of applied health communication, designed to encourage men to be screened for prostate cancer. One in eight men in the United States will be diagnosed with prostate cancer in his lifetime. However, while the incidence rate of prostate cancer is increasing—particularly of advanced-stage disease—the number of men choosing to be screened is declining (American Cancer Society, 2025).This study explores the barriers to men being screened, both in the literature and in my personal experience. Among those …

Self-Determination Skills In Inclusive Education In Riyadh City; Perceptions Of Intellectual Disabilities Teachers, Samirah Alzahrani

USF Tampa Graduate Theses and Dissertations

Literature indicates that self-determination is critical for success in all aspects forstudents with intellectual disabilities. Nonetheless, gaps remain in research on self-determination in the KSA special education context, and the implementation of practices for teaching self- determination skills is notably constrained. As a result, this qualitative study explored the perspectives of special education teachers in the Kingdom of Saudi Arabia on the concept of "self-determination" among students with ID in inclusive education, and examined their perceptions of the significance of incorporating these skills into instruction for students with ID. Data was collected through semi-structured interviews. The data were analyzed using …

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 …

Reading Echoes Of Homer In Plato: Finding Philosophical Insights By Reading Plato's Dialogues As Poiēsis, Stephen R. Lasse

USF Tampa Graduate Theses and Dissertations

Reading Echoes of Homer in Plato: Assessing the legitimacy of the macro-level thesis that approaching Plato from the poetic tradition starting with Homer generates philosophical insights not available when reading his dialogues as the first installments in the Western tradition of philosophy. It begins by identifying equivocal nuances in the dramatic content of Plato’s dialogues that are left unexplored by the current standard approach that attributes a progressive developmentalist approach to Plato’s authorial intent before suggesting an alternative unitarian approach to Plato as an author who maintains an unchanged point of view throughout his corpus of work. It then identifies …

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 …

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), …

Can Hope Be Changed In 30 Minutes? The Development, Refinement, And Pilot Evaluation Of A Hope-Based Single-Session Intervention, Aileen Kangavary

USF Tampa Graduate Theses and Dissertations

Background: Although mental health problems are on the rise among youth, nearly 80% do not access treatment. Schools serve as key settings to address adolescent mental health and wellness needs given the substantial barriers that limit access to community-based mental health services. Despite this potential, schools often face implementation challenges. Therefore, scalable and accessible approaches are needed to meet the growing demand for adolescent mental health support. Single-Session Interventions (SSIs) represent a promising, cost-effective, and digital avenue for providing timely mental health support to youth. Increasingly, research conceptualizes mental health through a two-dimensional framework that includes the presence of well-being …

A Portable Device To Elicit Sensory Trick And Monitor Forearm Muscle Activity In Pianists With Musician’S Dystonia, Josef Franczak

USF Tampa Graduate Theses and Dissertations

Musician’s Dystonia (MD) is a condition that can be acquired in professional musicians,causing involuntary contractions and the loss of fine motor control. The most common pharmaceutical treatment, botulinum toxin injections, has been shown to have side effects of muscle weakness and atrophy. The sensory trick, shown to temporarily relieve symptoms of dystonia, has potential to be used as an alternative or alongside current therapies, allowing patients with MD to return to playing music professionally. To systematically deploy the sensory trick and monitor forearm muscle activity, the first prototype of the Wearable Sensorimotor Integrator (wSMI) has been developed.

The wSMI is …

Under Pressure: Effects Of The Hot Docs Behavioral Parent Training Program On Caregiver Blood Pressure, Bria N. Ferera

USF Tampa Graduate Theses and Dissertations

Chronic stress is heightened for caregivers of children with heightened disruptive behaviors. With chronic stress supported as a major factor leading to maladaptive parenting and caregiving practices, exploring new ways to collect data on parenting stress remains a critical research priority (van der Lubbe et al., 2024). Behavioral Parent Training (BPT) programs are linked to improved parent-child relationships and reduced problem behavior (Armstrong, 2006; Agazzi, 2021; Patrusky, 2025). However, few studies have used physiological biomarkers in conjunction with self-reported measures to explore connections in this area. Similarly, other physiological considerations are rarely considered upon evaluation of the impacts of BPT …

Where Diagnosis Meets Daily Life: Testing Theoretical Models Of Social Anxiety, Jessica A. Birg

USF Tampa Graduate Theses and Dissertations

Social anxiety disorder (SAD) is thought to persist through self-reinforcing cycles linking threat perception, fear of evaluation, avoidance, and social behavior. This dissertation examined whether the nature of these daily processes generalize across individuals, cluster into subgroups, or vary by social anxiety severity. Two ecological momentary assessment (EMA) studies were conducted: a community sample with and without SAD (Study 1: N = 96; five prompts per day across two 14-day bursts) and an undergraduate sample (Study 2: N = 129; six prompts per day across 14 days). Momentary variables included social anxiety, avoidance motivation, and threat and safety cues (hurt …

A System Dynamics Perspective Of User Adaptation: The Case Of Exoskeleton Technology, Enzo Novi Migliano

USF Tampa Graduate Theses and Dissertations

Technology implementation is a common occurrence in organizations to which workers must adapt. Although research on workers' technology acceptance is widely spread, research on the workers' technology adaptation process is less represented in the literature. The discrepancy in the literature permeates research on new technologies currently being implemented in organizations, such as occupational exoskeletons. As in other technologies, the variance research perspective dominates the literature on exoskeleton implementations. The current thesis aims to foster process research by formalizing the coping model of user adaptation (Beaudry & Pinsonneault, 2005) and exploring research questions regarding workers' adaptation to general technology and exoskeletons. …
