Associations Between Sexual And Gender Minority Stress Exposure And Schizophrenia-Like Experiences In The South, Lillian A. Hammer

Dissertations

Background: Negative experiences related to one’s minority identity serve as stressors contributing to mental health concerns for those identifying as a sexual and/or gender minority (SGM). SGM groups have greater severity of some mental health symptoms than non-SGM individuals, yet it is poorly understood whether these findings extend to schizophrenia-like experiences (SLEs). SLEs are associated with significant distress and may indicate risk for the development of schizophrenia-spectrum disorders. Associations between exposure to minority stress and SLEs are underexplored. This study aimed to fill this gap by assessing whether exposure to SGM-related minority stress was related to SLEs using ecological …

Combat And Beyond: Predictors Of Post-Traumatic Growth In War Zone Veterans, Gabriela Crucianu

Dissertations

Veterans returning from combat often face psychological challenges, but many also experience posttraumatic growth (PTG), which refers to positive changes that can emerge after trauma. This study explored whether coping strategies, personal characteristics, social support, and combat exposure were associated with PTG in a sample of 42 war zone veterans using quantitative and qualitative methods. Participants completed validated measures assessing combat exposure, coping strategies, social support, personal characteristics (e.g., optimism), and PTG. Regression analyses showed that combat exposure, coping strategies, and optimism were not significant predictors of overall PTG. However, combat exposure was associated with appreciation for life, a dimension …

Familismo: Exploring A Culturally Sensitive Correlation Between Parentification And Relationship Satisfaction Amongst First Generation Mexican-American Adults Through An Attachment Theory Lens, Ana K. Perez

Dissertations

Parentification refers to the role reversal of children who take on adult responsibility to care for family members. This role is often filled by Mexican-American children as a result of immigration and assimilation. This study explored the relationship between parentification and adult romantic relationship satisfaction among first-generation Mexican-American adults, with particular attention to the moderating roles of attachment styles and perceived unfairness. While earlier research has linked parentification to mental health challenges, few studies have examined its long-term impact on intimate relationships, including relationship satisfaction and experiences of intimate partner violence. A total of 132 participants completed an online survey …

"Please Put The Phone Down!": Self-Determination Theory Applied To Parental Social Media Mediation, Benjamin A. Dolowich

Dissertations

The majority of adolescents and young adults use social media (Chaddock, 2024; Coyne et al., 2013). Parents are faced with the challenge of considering the role social media may play in their children’s lives (Valkenburg et al., 2013). Using self-determination theory as a framework (Deci & Ryan, 2000), we investigated psychological needs as one mechanism connecting parental social media mediation strategies with well-being and emotional distress in a sample of young adults. Participants were 244 undergraduate students who completed online questionnaires. The results highlighted that controlling styles of parental social media mediation have an association with emotional distress. Psychological needs …

Servingness In Solidarity: How Filipina/X/O American Student Organizations Cultivate Belonging, Clarissa Mae Lico Calimbas

Dissertations

Filipina/x/o American college students represent one of the largest Asian ethnic subgroups in the United States, yet their educational experiences remain underexamined within institutional research and higher education scholarship. Aggregated under the broader Asian American category, Filipina/x/o American students are rendered invisible by data practices that obscure the distinct colonial histories, socioeconomic realities, and identity negotiations. This qualitative study examined how Filipina/x/o American students at Pacific State University (PSU) describe their involvement in Filipina/x/o American Student Organizations (FASOs) and how that involvement shapes their sense of belonging, cultural identity development, and academic persistence. Guided by a critical race phenomenological framework …

Special Education Teacher's Perceptions Of Genai For Creating Individualized Lesson Plans, Mahadevan Iyer

Dissertations

In the United States today, 7.3 million students are receiving special education (SPED) services under the Individuals with Disabilities Education Improvement Act (IDEIA, 2004). Rules and regulations governing SPED help ensure that SPED students receive good quality education. Section 1414(d) of IDEIA requires schools to provide specialized academic instruction as per each student’s Individualized Education Program (IEP). SPED teachers are responsible for accommodating, scaffolding, and individualizing the curriculum to meet the goals specified in the IEP. Defining the individualized curriculum is an added responsibility for a SPED teacher. This study examined SPED teachers’ access to instructional materials that implement EBPs …

Vision With Grace: Intersectionality Of Education And Spirituality, Preeti Jha

Dissertations

Contemporary educational leaders face increasingly complex challenges, systemic inequities, educator burnout, and demands for transformation, yet existing leadership frameworks fail to address the inner lives and spiritual practices that sustain such demanding justice work. While research demonstrates spirituality's role in leadership effectiveness, this dimension remains largely unexplored in educational research, particularly regarding how spiritual consciousness shapes daily practices and social justice engagement. This qualitative study will examine how spirituality shapes educational leadership and social justice engagement through portraiture methodology and in-depth interviews with three spiritually aligned educational leaders in Northern California. Drawing upon the Bhagavad Gita, Spiritual Leadership Theory, and …

The study found that students who …

The Relationship Between Adverse Childhood Experiences, Protective And Compensatory Experiences, And Parenting Attitudes Among Fathers, Kylie Schmidt

Dissertations

Adverse childhood experiences (ACEs) are defined as potentially traumatic events that occur in childhood particularly between the ages of 0 and 17 years that negatively influence long-term health, relational functioning, and parenting practices (Centers for Disease Control and Prevention, 2026; Felitti et al., 1998; Merrick et al., 2019). Conversely, protective and compensatory experiences (PACEs) have emerged as protective factors that foster resilience and possibly buffer against the adverse outcomes of ACEs (Narayan et al., 2018). As the existing research has greatly focused on mothers, little is known about how men’s early life experiences shape their parenting attitudes, particularly during the …

Dissertations

This study examined the relationship between perceived social support and academic self-efficacy, or academic confidence, among Black doctoral students in psychology programs at predominantly White institutions (PWIs). Grounded in self-efficacy theory, the study was designed to explore whether perceived social support was associated with and predictive of students’ academic confidence. A quantitative, cross-sectional design was used, and data were collected using adapted versions of the Multidimensional Scale of Perceived Social Support (MSPSS) and the Academic Self-Efficacy (ASE) scale. The sample consisted of 60 Black doctoral students enrolled in psychology programs at PWIs across the United States. Descriptive statistics indicated the …

The Ramifications Of Covid-19 On Young Adults With Ocd, Clare E. Mcintosh

Dissertations

The coronavirus disease of 2019 (COVID-19) pandemic was a profound event in modern history, contributing to significant disruptions on a societal and individual level. This period of time was marked by elevated uncertainty and fear among individuals. COVID-19 contributed to deterioration in not only physical health but also psychological well-being. One mental health condition frequently under-examined and saturated with misconceptions is obsessive-compulsive disorder. Obsessive-compulsive disorder is a condition characterized by the presence of obsessions and/or compulsions. Intolerance of uncertainty is a core component of the condition, and the pandemic was riddled with unpredictability. The purpose of this study was to …

Offline And Thriving: Understanding The Professional And Personal Lives Of Non-Social Media Users In A Digitally Dominant Era, Bhargava Mantena

Dissertations

Existing research has treated voluntary social media abstinence as the absence of users rather than as a condition worth study. This mixed-methods study examined its psychological and occupational correlates. Adults aged 21 to 65 reporting abstinence from all major platforms for six months or more completed three validated instruments measuring mental well-being, work engagement, and perceived social isolation; a purposive subsample of 12 took part in semi-structured interviews. The analysis set comprised 120 participants, below the 128 indicated by the a priori power analysis. Research Question 1 could not be tested as approved, because no active-user comparison group was recruited; …

Exposing And Addressing Machine Learning Brittleness Through Constraint Solving, Muyeed Ahmed

Dissertations

Machine Learning (ML) implementations are fundamentally brittle: nondeterministic, inconsistent, and prone to overfitting; however, constraint solving can be used to systematically expose, quantify, and address this brittleness.

This dissertation first establishes that widely-used implementations of popular ML algorithms are nondeterministic (producing different outputs on the same input, across different runs) and inconsistent (different implementations of the same algorithm producing different outputs on the same input). This is more prevalent in Unsupervised Learning (UL) implementations where, due to the lack of a ground truth, subtle execution errors can go unnoticed and are difficult to verify. Nondeterminism and inconsistency also introduce security …

Engineered Porous Structures For Propellants Using Additive Manufacturing, Elbert Caravaca

Dissertations

Foamed polymers are widely used today for shock absorption and packaging materials to prevent damage to their contents. Typical foamed densities vary from 0.1 g/cm³ to 0.4 g/cm³ depending on the polymeric materials used. There is a need to explore foaming densities above 0.4 g/cm³ for propellants with highly engineered surface area progression for increased combustion performance. One way to achieve this is through highly controlled and engineered graded foam structures. To further exploit this approach, additive manufacturing coupled with a tunable means to generate foamed structures is the target of this work. To generate foam structures …

Development Of Ultrafast Protein Digestion And Standards Free Quantitation Methods For Mass Spectrometric Analysis, Praneeth Ivan Joel Fnu

Dissertations

A wide variety of biologically important molecules, such as enzymes, antibodies, hormones, transporters and receptors are proteins by composition and they play key roles in biological functions such as cellular regulation, communication, metabolism and physiological function. Protein dysfunctions and abnormalities are associated with numerous diseases, making proteins critical targets for understanding disease mechanisms and developing therapeutic interventions. Protein-based therapeutics such as monoclonal antibodies, hormones and vaccines gained popularity due to their high specificity, efficacy, and ability to treat complex diseases that are often difficult to address with small-molecule drugs.

Given the important role of proteins in a variety of biological …

The Inverse Elasto-Acoustic Problem, Patrick Grice

Dissertations

A stable and numerically efficient boundary integral method formulation of the elasto-acoustic problem is presented, based on Fourier analysis. The method generalizes well to multiple scattering. The Frechet derivative of the elasto-acoustic problem with respect to shape perturbations is derived, and geometric flow theory is used to design stable numerical methods for the simulation of moving boundaries. The shape derivative is used to define a regularized Gauss-Newton algorithm for shape fitting of elasto-acoustic scatterers.

Geographic And Environmnetal Influences On Color Pattern Similarity Between Coral Snakes (Genus: Micrurus) And Their Lookalikes, Anthony Sena

Dissertations

Venomous coral snakes and their lookalikes are often regarded as a classic example of Batesian mimicry, whereby a harmless species imitates a harmful species. The existing literature regarding coral snake resemblance presents a divisive stance on whether Batesian mimicry is the primary driver of shared color patterns or if alternative factors are responsible. While recent literature largely favors the Batesian hypothesis, empirical support remains inconsistent, and the specific geographic and interpretation of the conditions required for mimicry lacks consensus within the scientific community.

To evaluate the mechanisms maintaining these phenotypes, a quantitative, multivariate framework was utilized to analyze 400 museum …

Solar Wind - Magnetosphere - Ionosphere Coupling Processes Through Small-Scale Magnetic Flux Ropes, Youra Shin

Dissertations

Small-scale magnetic flux ropes (SMFRs) in the solar wind are examined to determine their properties in the near-Earth upstream region and their effects on geospace. Although SMFRs are observed frequently in the solar wind, their statistical behavior near Earth and their role in solar wind-magnetosphere-ionosphere coupling remain insufficiently constrained. In this dissertation, an automated Grad-Shafranov reconstruction technique is applied to magnetic field and plasma measurements from MMS and Wind, and ionospheric responses are investigated using geomagnetic indices and SuperDARN observations. During the survey period, MMS has an apogee of approximately 25-29 R_E. This orbital configuration allows the near-Earth …

Promoting The Bipartisan Dimension Of Political Leadership: A Study Of The Impact Of A Normative Intervention With Newly Elected Members Of Congress, Jaime M. Ruvalcaba

Dissertations

The U.S. political system is more polarized now than at any time in the past century, as evidenced by the rise of political incivility, legislative gridlock, and hyperpolarization. To date, most studies and efforts have focused on institutional strategies to explain, transform, and mitigate the challenges posed to the political environment. By contrast, little attention has been paid to the normative or values-based behaviors of leaders to either explain or influence political leadership in ways that positively impact the political environment. Fortunately, some organizational programs, like Harvard’s Bipartisan Program for Newly Elected Members of Congress, have taken a different tack, …

Through Their Lens: Co-Teachers’ Effective Strategies That Support Ells And Swds In Mathematics Inclusion Classrooms, Cheryl A. Bentham

Dissertations

Abstract

The current dialogue surrounding minoritized students in mathematics classrooms often focuses on deficit-based narratives that compare their competency to unrealistic norms. Such continuous negative narratives only serve to add another layer of marginalization to students who are already underserved, notably Black and Hispanic students, and subgroups comprising ELLs and SWDs. This qualitative case study explored the research-based strategies utilized by three co-teacher pairs to support ELLs and SWDs in Algebra inclusion classrooms. Vygotsky's (1978) social constructivist theory guided the study, which posits that learning occurs through social interactions, environmental influences, and support from more knowledgeable others. The data were …

Teacher Experience And Perception Of Feedback Literacy In The International Baccalaureate Diploma Programme, Carla B. Mills

Dissertations

Writing instruction in schools remains a significant area of concern even after decades of awareness that students are not performing at proficient levels upon high-school graduation. This phenomenographic case study investigated teacher feedback literacy at the secondary level through interviews with teachers of writing-intensive International Baccalaureate Diploma Program courses and document analysis. Areas of feedback literacy strength included teacher awareness of designing positive class environments, attending to the socio-emotional needs of their learners, extensive use of both rubrics and exemplars, and frequent provision of verbal feedback. Document analysis revealed the presence of explicit instruction in written feedback, rubric use, and …

Ai You Can Trust: Understanding The Role Of Structural Assurance And Situational Normality In The Use Of Generative Ai, Olushola Bunmi Abayomi

Dissertations

The rapid growth of generative artificial intelligence (GenAI) has increased its use in productivity, content creation, and decision support; however, adoption depends on user trust, as GenAI performs tasks that are often associated with human judgment. Drawing on the Trust in Technology Model, this dissertation examines how structural assurance and situational normality influence Trust in GenAI, and how Trust in GenAI affects trusting intentions and users' willingness to depend on GenAI. Structural assurance and situational normality, captured through several factors, were modeled as antecedents of Trust in GenAI and, in turn, trusting intentions. The model was tested using survey-based experimental …

“Dynt Of Dede:” Reading The Medieval Combat Scene Through The Helmet-Cleave Motif, Andrew Sherwood Thomas

Dissertations

This research explores the continuity of chivalric combat descriptions throughout medieval literature. By tracing the history, development, and distribution of the helmet-cleave motif, this study is able to examine combat scenes spanning a wide reach of time, genera, and language. The purpose of this work is to suggest a reading methodology for the chivalric combat scene that appropriately situates it in its cross-textual context and so reveals the nuance of its expression and the value in its study.

Despite the volume of surviving combat descriptions in medieval literature, they remain underrepresented in the scholarship due to their apparent repetitious and …

Black Protection: Black Social Media Competency And Urban, Black Adolescents On Social Media, Taylor A. Williams

Dissertations

While urban, Black adolescents interact with racial identity content on social media, their identity is primarily shaped through offline experiences and later reflected or reinforced online. Through the concept of Black social media competency (B-SMC), this study examined the relationships between Black urban adolescents’ social media use, exposure to race-related content, and experiences navigating the digital environment. The study used a qualitative design, grounded in the phenomenological and ecological frameworks, with 21 adolescents recruited from two urban, Midwestern schools and programs to participate in semi-structured interviews, and data were analyzed using thematic analysis to identify patterns in how the participants …

The Relationship Between Depression And Cognitive Proficiency Index Across Biological Sex, Angela N. Ferdinardo

Dissertations

Depression is a widely studied mood disorder, and understanding its effect on cognitive functioning has become an important area of research. While research has examined relationships among depression, working memory, and cognitive deficits, limited research has explored depressive symptoms and cognitive proficiency across biological sex. Depression manifests similarly in men and women, though men are more likely to experience irritability, impulsivity, and anger, while women tend to experience sadness, stress, and sleep disturbances (Johns Hopkins Medicine, 2023). Women are also more likely to seek treatment and cope differently than men. This study examined the relationship between depression and cognitive proficiency …

Association Between Stress Mindset, Psychological Symptoms, And Psychosocial Risk In Liver Transplant Patients, Sarah Kay Brill

Dissertations

Psychosocial functioning is a central component of liver transplant evaluation, yet less is known about how cognitive factors, such as stress mindset, relate to transplant readiness. The present study examined the association between stress mindset and psychosocial risk, as well as its relationship with depressive symptoms, anxiety, and perceived stress among patients undergoing liver transplant evaluation. Patients included 62 adults completing standard pre-transplant assessment measures, including the Stress Mindset Measure–Specific (SMM-S), Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Perceived Stress Scale (PSS). Hierarchical logistic regression analyses indicated that stress mindset was …

Seeing The Unspoken: A Pilot Eye-Tracking Study Of Moral Injury Among Veterans, Eva M. Valdez

Dissertations

This pilot study examined associations between self-reported moral distress, state distress, combat exposure, deployment history, and maximum pupil reactivity among veterans diagnosed with PTSD. Participants viewed neutral and morally relevant images while pupil responses were recorded using eye-tracking technology. Self-report measures included moral distress severity, exposure to potentially morally injurious events, Subjective Units of Distress Scale (SUDS) ratings, total deployments, number of combat deployments, and Combat Exposure Scale scores. Maximum pupil reactivity was calculated by subtracting the mean z-scored maximum pupil response during neutral image presentations from the mean z-scored maximum pupil response during morally relevant image presentations. This variable …

The Legacy Of Trauma: Exploring The Effect Of Generational Stress On Gut Health And Mental Well-Being In Black Women, Jocelynn Jones

Dissertations

This dissertation examines how generational trauma and chronic stress may relate to gut health and mood outcomes among Black women. Using a literature review design, this work brings together research on intergenerational trauma, gendered racism, Superwoman Schema, weathering, allostatic load, mood disorders, reproductive health disparities, and the microbiota-gut-brain axis. The central argument is that depression, anxiety, gastrointestinal symptoms, fatigue, reproductive vulnerability, and healthcare mistrust should not be understood as fully separate concerns when they may be shaped by shared stress conditions. The proposed integrated model does not claim that trauma directly causes gut dysbiosis or mood disorders. Instead, it suggests …
