Instead, he attended the University of Iowa, where he earned a master's and doctorate in political science. In 1981, he joined the University of Nebraska-Lincoln as an assistant professor of political science and rose quickly through the ranks. Initially, he studied the reasons that members of the U.S. Congress retire. This led to a longer-term collaboration with Kevin Smith and …

Driving-Related Challenges For Autistic Youth, Jeong-Heun Kim

ETDs from 2020-2029

Individuals with autism spectrum disorder (ASD) often face barriers to driving. Despite evidence that they have potential to drive safely, some unique challenges exist, manifested in a substantially lower licensure rate than typically developing (TD) peers and restricted driving patterns among this population. Therefore, the overarching goal of this dissertation project was to investigate driving-related challenges that young autistic people face. Both objective and subjective measures were used to comprehensively explore this research topic. The first two papers focused on investigating perceptual, cognitive, and behavioral factors underlying hazard response using data from a total of 34 licensed drivers (17 with …

Altered But Adaptive: Network Integration In Pediatric Acute Lymphoblastic Leukemia Survivors A Diffusion Mri Graph Theory Analysis, Amanda Cook

ETDs from 2020-2029

Pediatric acute lymphoblastic leukemia (ALL) survivors face treatment-related risk for late-emerging cognitive difficulties. Chemotherapy can disrupt white-matter structure leading survivors to experience subtle but persistent challenges with processing speed, working memory, and executive functioning. However, cognitive outcomes vary widely even among survivors with similar treatment exposures. To better understand this variability, this study examines how the brain adapts after treatment and how that adaptation is shaped by the environment. This study used diffusion magnetic resonance imaging (MRI) connectomics to characterize white matter network organization in 18 pediatric ALL survivors compared with 20 typically developing controls (ages 10-18). Structural connectomes were …

Mindfulness Across Media: Examining The Effects Of Audio, Audio-Visual, And Virtual Reality Mindfulness Interventions On Social Media Mindsets And Psychological Wellbeing, Rashmi Salian

ETDs from 2020-2029

Social media is so deeply ingrained and integrated into daily life that concerns about its impact on psychological wellbeing continue to grow, prompting pressing questions about how to foster healthier and more intentional use of technology. Recent studies suggest that low-agency mindsets toward social media lead users to develop habitual usage patterns and ambiguous information consumption behaviors, both of which negatively impact psychological outcomes. However, limited research is available on mechanisms that could effectively alter these mindsets. This study uses an experimental methodology to investigate whether mindfulness interventions delivered through varying levels of media immersion can improve psychological mindsets toward …

Testing The Impact Of Sexual Minority Stress On Endorsement Of Prospective Behaviors Related To Borderline Personality Disorder Among Lesbian, Gay, Bisexual, And Queer Adults, E. Elisa Carsten

USF Tampa Graduate Theses and Dissertations

Sexual minority individuals face increased risk for numerous forms of psychopathology compared to heterosexual individuals, including borderline personality disorder (BPD). Previous investigation into the causes of these mental health disparities highlights several sexual minority-specific factors that may render sexual minority individuals uniquely vulnerable to meeting criteria for a BPD diagnosis, including chronic exposure to minority stressors, such as sexual orientation-based discrimination and stigmatizing beliefs. Some scholars have argued that the relevance of these minority-specific stressful experiences hampers the utility of a BPD diagnosis among members of this historically marginalized population. The present study experimentally tested the influence of minority stressors …

Independent Living Skills For The Aging Population Of Adults With Disabilities, Sara K. Fetter Otd, Otr, Jennifer L. Martin Otd, Otr, Cht, Clt, Michele L. Mccarroll Phd, Faacvpr, Acsm-Ccep, Ccrp, Lssbb

Developmental Disabilities Network Journal

Adults with intellectual disability (ID) are living longer and increasingly outlive family caregivers. Strengthening independent living and vocational skills has therefore become a critical public-health priority. Occupational therapy (OT) can address this need through person-centered, community-based programming. This paper describes the co-design, delivery, and preliminary outcomes of a short occupation-based curriculum intended to enhance autonomy and work readiness in aging adults with ID. In partnership with a Dallas, Texas nonprofit, the authors conducted a needs assessment and created an 8-session course rooted in the Independent Living Model and the Occupational Competence Model. The curriculum addressed four domains (physical health, financial …

Development Of An Adaptive Pelican Crossing Model Using Fuzzy Logic In Mixed Traffic Conditions, Manazil Adam, Andyka Kusuma, R. Jachrizal Sumabrata

Smart City

Traffic management at at-grade pedestrian crossing facilities (pelican crossings) in highly populated areas, such as the Universitas Indonesia Station, faces significant inefficiency challenges. During peak hours, the fixed-time system is frequently disabled and replaced with subjective manual control by security personnel, thereby triggering irregular stop-and-go cycles and a high accumulation of vehicle delays. This study aims to develop a hybrid adaptive control model integrating Computer Vision, Genetic Algorithm (GA), and Fuzzy Logic to optimize intersection performance under mixed traffic conditions. The research methodology begins with the extraction of traffic and pedestrian characteristic data, calculated manually through recorded field observations. This …

Breaking Bread And Barriers: Interprofessional Strategies To Improve Mental And Nutritional Health In Family Caregivers, Candy Ratliff

The Journal of the Research Association of Minority Professors

Family caregivers provide essential unpaid support to individuals with chronic illness, disability, dementia, and age-related decline; however, caregiving responsibilities often place caregivers at increased risk for psychological, physical, nutritional, and social challenges. This literature review examines the mental health and nutritional implications of family caregiving and explores barriers that contribute to declining caregiver wellness. Findings reveal elevated rates of depression, anxiety, emotional exhaustion, social isolation, food insecurity, sleep disturbances, financial strain, and chronic stress among caregivers. The literature further highlights the interconnected relationship between mental health, nutrition, and overall quality of life. Given the multidimensional nature of caregiver burden, interprofessional …

Surviving And Thriving: The Indigenous Migrant, Danna Guzman-Rodriguez

Honors Theses

This literature and cultural study highlights the generation of children of indigenous immigrants and the relationship with their indigenous identity and culture. This unique experience is complex and encapsulates issues such as indigenous cultural survival, homogeneity, globalization, and lack of cultural identity. Exploring the Totonac community in La Chaca, Veracruz in Mexico, allows for a deeper explanation of this experience. Speakers of Totonac and other indigenous languages often migrate to countries such as the United States and carry such cultural ties with them. What happens to these ties after moving to a Western-dominated country where globalization favors English and Western …

A Phenomenological Study Of Binge Eating Disorder And Trauma In Black Women Managed By Religious Coping, Nicole Rae Skinner

Doctoral Dissertations and Projects

The purpose of this phenomenological study was to understand the relationship between trauma, binge eating disorder (BED) and religious coping among Black women in America. Black women are faced with stereotypes such that they are expected to be strong, resulting in avoidance behaviors related to emotions. Core to the issue of BED is an inability to manage difficult emotions in a healthy manner, thus leading to the negative pattern of bingeing. Therefore, guiding this research were two key theories: Gross’s emotional regulation theory and Pargament’s theory of religious coping. The emotional regulation theory addresses how emotions are experienced and an …

Doctoral Dissertations and Projects

The purpose of this phenomenological study is to explore the lived experiences of African American heirs’ property owners in the Southeastern United States. Bowen’s Family Systems Theory (BFST) and the Theory of Resilience and Relational Load (TRRL) are the lens through which these experiences are viewed. Each theory provides applicable concepts that guide the query with the participants as they share their interpretations of the phenomenon. Furthermore, the study seeks to understand the biopsychosocial aspects of the interpersonal relationships that family members confront when addressing issues of co-tenancy as owners of inherited land. This hermeneutic phenomenological study employed a hybrid …

A Link Between Emotional Intelligence, Age, And Diverse Learners, Christina Jedlicka Blake

Doctoral Dissertations and Projects

This quantitative comparative study explored the complex relationship between emotional intelligence (EQ) and Learning Differences (LDs), focusing on academic, social, and emotional development of adolescents diagnosed with specific learning disabilities (SLDs), attention deficit hyperactivity disorder (ADHD), and high- functioning autism spectrum disorder (ASD). The study investigated whether differences in EQ exist between students with and without LDs and whether age influences EQ development. The 102 participants included male and female students in grades 6-12, ages 11-18, attending a Christ-centered college preparatory school. Students completed a 30-question EQ questionnaire during the researcher’s class time, and online surveys were coded to identify …

State Government, The Forgotten Cyber Actor, Joshua D. Strubel

Doctoral Dissertations and Projects

Cyber incidents are among the most pervasive threats facing the United States, with the FBI recording over 859,000 reported attacks and an estimated $16.6 billion in losses in 2024 alone. Despite widespread recognition that effective cyber defense requires a whole-nation approach, the existing research literature overwhelmingly focuses on federal policy, leaving state governments as largely overlooked actors. This study addresses that gap by examining the research question: How does state cybersecurity policy affect malicious cyber actors' frequency of operations? Drawing on multilinear regression analysis augmented by Random Forest machine learning models, this study evaluates the relationship between state-level cyber deterrence …

To What Extent Do Different Types And Dosages Of Cannabinoids Have In Treating Anxiety Disorder, Lourdes Cristina Garcia Carrillo

Doctoral Dissertations and Projects

This mixed-methods study investigated the efficacy of various cannabinoid types and dosages in treating anxiety disorders among young adults (19–23), examining cannabis's role in regulating a deregulated endocannabinoid system. Fourteen participants tracked real-time anxiety symptoms, strain type, dosage, and affective states using the Releaf App. Quantitative analyses included repeated-measures ANOVA and Pearson correlation, complemented by quantitative content analysis of affect descriptors. Key findings revealed a statistically significant reduction in self-reported anxiety symptoms following cannabis use (p < .001, partial 2 = .97), supporting the hypothesis that cannabis can regulate a deregulated endocannabinoid system. No significant differences in anxiolytic effects were observed among Indica, Hybrid Indica/Sativa, and Hybrid Sativa/Indica strains. The optimal dosage for perceived anxiety relief appeared to be higher than initially hypothesized, with a moderate-to-strong association between dosage and anxiety relief (r = .662, p = .0099). Participants overwhelmingly reported positive affective states, such as "calm," "peaceful," and "relaxed," post-cannabis use, with no negative descriptors observed in the analyzed data. These results suggest that cannabis can serve as a short-term coping strategy for anxiety in young adults, leading to perceived emotional regulation.

Children With Cerebellar Malformations And Co-Occurring Autism: A Phenomenological Study Exploring Challenges Faced With The Dual Diagnosis Process, Service Acquisition, And Psychosocial Impacts, Ladeana W. Gambill

Doctoral Dissertations and Projects

Parents of children who have been diagnosed with cerebellar malformations, such as Dandy-Walker Malformation, often face confusion and frustration as they are given uncertain prognoses about their child’s future. The uncertainty is further compounded when there are concerns for autism spectrum disorder (ASD), and testing is sought, with conflicting answers on whether their child has autism or not. Acquisition of autism-specialty services may be delayed if a diagnosis of autism is not received in a timely manner. The purpose of this interpretive phenomenological study was to understand the lived experiences and challenges faced by parents of children with cerebellar malformations …

Strengthening The Mind: Evaluating Emotional Intelligence As A Tool To Combat Anxiety In Youth Soccer, John P. Hill

Doctoral Dissertations and Projects

Competitive anxiety is a significant challenge for adolescent soccer players, contributing to psychological distress and early sport withdrawal, and approximately 70% of youth athletes quit organized sport by age 14. Emotional intelligence, the capacity to recognize, understand, and regulate emotions, represents a promising and trainable intervention target, yet few studies have examined structured EI programs with youth soccer populations using rigorous experimental designs that include a parallel control group. This quantitative intervention study examined the effect of an emotional intelligence intervention on competitive anxiety among youth soccer players, including whether individual emotional profiles and gender moderated outcomes.

Identifying and implementing solutions to mitigate the effects of absenteeism and workers’ compensation claims are critical to organizational sustainability. This quantitative study seeks to determine if workplace health and wellness programs decrease absenteeism and reduce workers’ compensation claims levels among public sector employees. Post-positivism and functionalism provide this study with a theoretical underpinning. The variables of interest were …

How Are Depression And Anxiety In Biracial Black–White Adults Related To Monoracial Familial Connectedness Throughout Life?, Cary M. Steffey

Doctoral Dissertations and Projects

The multiracial population is the fastest-growing minority group in the United States, yet their mental health and familial experiences are insufficiently studied. Due to their complex racial backgrounds, unique life experiences, and diverse social connections, multiracial individuals endure mental health issues that differ from those of many other populations, including their family relationships. Some of these differences include how these relationships affect life experiences and mental health status. This quantitative study examined psychological well-being among multiracial individuals, with a focus on relationships with monoracial family members. This study hypothesized that greater familial support predicts improved mental health outcomes. The study …

Caregiver Depression And Psychological Distress As Predictors Of Substantiated Maltreatment In Nscaw Ii (Wave 2 Cps Sample): A Quantitative Archival Study, Gloria Forotan

Doctoral Dissertations and Projects

This quantitative archival analysis examined whether caregiver mental health is associated with child maltreatment outcomes through CPS involvement, using the National Survey of Child and Adolescent Well-Being II (NSCAW II), Wave 2. Child maltreatment remains a persistent public health concern with long-term effects on children's emotional, psychological, and physical development. Although caregiver mental health is consistently identified as a significant risk factor for maltreatment, few studies have utilized nationally representative child welfare data with standardized measures to test these associations.

Caregiver mental health variables were operationalized using NSCAW II indicators of major depression and depressive symptoms (DP2), psychological distress (K6 …

The Role Of Resilient/Protective Factors In Adolescence As A Buffer Among Adults With A History Of Childhood Trauma And Symptoms Of Depression In Adults, Michaela L. Fox

Doctoral Dissertations and Projects

Childhood trauma includes adverse experiences during early development, such as physical, emotional, sexual, or verbal abuse and neglect, and is associated with negative outcomes, including depressive symptoms in adulthood. This study examined whether protective factors during adolescence are related to adult depressive symptoms among individuals with a history of childhood trauma. Two research questions guided the study: (a) Is there a difference in adult depressive symptoms between individuals with minimal versus significant protective factors during adolescence, and (b) Is there a statistically significant relationship between adolescent spirituality and adult depressive symptoms? A quantitative, correlational design was used with self-report surveys …

Mental Toughness In Motherhood: A Qualitative Phenomenological Approach To Advancing Developmental Understanding, Mary Kauffman

Doctoral Dissertations and Projects

This qualitative phenomenological study explored how mothers define, experience, and describe mental toughness within the developmental context of motherhood. Mental toughness has been extensively examined in performance-based domains such as sports, education, business and military settings. Limited research has investigated how this construct appears or manifests in caregiving roles. Understanding mental toughness in motherhood may inform how mothers are supported psychologically and contribute to future frameworks, interventions, and systems designed to strengthen maternal well-being, adaptation, and long-term functioning. Guided by Bandura’s self-efficacy theory, which focuses on the perceived ability of individuals to navigate adversity, this study examined mental toughness as …

Infertility In The Military: A Lived Experience, Princess Gibbs

Doctoral Dissertations and Projects

Infertility can have negative effects on women; military women deal with so much from the military that dealing with infertility is an area that is underdeveloped. This qualitative phenomenological study explored infertility among women serving on active duty, using Lazarus' transactional theory of stress and coping to understand how it affects them. This study was guided by three research questions: (a) What are the lived experiences of women living with infertility who served on active duty in the United States military, (b) How do women living with infertility describe their experience of stress and coping while serving in active duty …

A Qualitative Study Of Gratitude Practice Among Won Buddhist Older Adults And Implications For Gerontological Social Work, Sungsim Lee

Dissertations

Although gratitude has been widely studied in social science, existing scholarship has largely relied on Western worldviews and quantitative research frameworks, limiting understanding of lived gratitude experiences within diverse spiritual and cultural contexts, including Eastern spiritual traditions. In Won Buddhism, originating in South Korea, gratitude holds a central place in spiritual life and is understood as an essential practice. This qualitative study explores the views of Won Buddhist older adult practitioners regarding their experiences, benefits, and challenges of engaging in spiritually grounded gratitude practice. Semi-structured interviews were conducted with 23 practitioners aged 65 and older from English-speaking Won Buddhist communities. …

Counting Your Chickens Before They Hatch: Understanding Anticipatory Savoring And How And Why People Approach Or Avoid The Anticipation Of Future Positive Events, Asura Louise Osborne

Master's Theses

In this study, discretion between the styles used to anticipate positive events is the focus of a Confirmatory Factor Analysis (CFA) conducted on the Index of Anticipatory Styles (IAS). The IAS is a 45-item survey used to measure types of savoring in response to future positive events. This work expands the savoring literature to examine approach- and avoidant-type anticipatory savoring. Approach-type anticipatory savoring discriminates between Enjoyment, Coping, Control, Recalled Anticipation, and Downplaying. Avoidant-type savoring parses between Avoidance of anticipation because events may not occur, Avoidance of anticipation because events may fail to live up to expectations, Jinxing, and Counterproductivity. CFA …

Pubertal Timing, Physical Activity, And Internalizing Symptoms In Adolescent Girls, Kirby Knapp

Master's Theses

Puberty brings marked changes in physical appearance, biological functioning, psychological well-being, and behavior, making it one of the most pivotal transitions in adolescence. Those who experience puberty earlier than their same-aged peers are at an elevated risk of psychological disorders and physical inactivity. Research shows that there are links between physical activity and psychological disorders, yet few have examined the directional relations between physical activity and internalizing symptoms or whether a certain amount of physical activity is necessary to prevent internalizing symptoms. Therefore, the current study examined (1) the directional relations between internalizing symptoms and physical activity, (2) the degree …
