Effect Of Vocational Training Programs On The Mental Health Of Indian Women Living In Contexts Of Urban Poverty (Or Urban Slums), Sriramya Potluri

Graduate Doctoral Dissertations

Women living in contexts of urban poverty (IWLCUP) experience disproportionately high rates of psychological distress, yet their mental health needs remain largely underrecognized. Beyond individualized explanations, broader ecological perspectives situate these women’s distress within previously underemphasized macrolevel forces and acknowledge the role of inequity and related structural disparities (e.g., economic, sociocultural, political etc.) in their oppression and disempowerment, thereby contributing to increased psychological vulnerability. Such frameworks call for intervention efforts that reduce individual psychological risk by addressing structural determinants proximally and distally impacting the lives of IWLCUP. Specifically, targeting poverty and economic insecurity might drive positive downstream effects that ultimately …

Cultural Responsiveness: Examining Assessments Of Therapists For Ethical And Clinical Outcomes (Create Clout), Tsotso T. Ablorh

Graduate Doctoral Dissertations

The Multicultural Counseling Competencies (MCC) and Multicultural and Social Justice Counseling Competencies (MSJCC) are well-researched and supported counseling practices for decreasing microaggressions in therapy and consequent attrition, lack of satisfaction, and maltreatment (Ratts et al., 2016; Sue et al., 1982). However, scholars critique existing methods for measuring therapists’ cultural responsiveness for being disconnected from therapeutic process and outcomes (Hays, 2020; Wilcox et al., 2020). This study examined which MSJCC measures associated with variables clinically and ethically relevant to better treatment outcomes and lower microaggressive, neglectful, and stereotypical treatment for hypothetical Black, female clients by White therapists. 62 White psychologists in …

Motor Imagery Eeg Decoding For Brain-Computer Interfaces: Structured Representation, Transfer, And Drift, Yiming Shen

Graduate Doctoral Dissertations

Motor imagery EEG decoding is often summarized by the accuracy of a final classifier, but the classifier is only the last stage of the pipeline. Before classification, the signal has already been shaped by preprocessing, feature extraction, source-session organization, and adaptation. This dissertation studies how feature representation, source-session transfer, and drift shape reliable MI-EEG decoding for brain-computer interfaces.

It first studies within-session decoding on public MI-EEG datasets using nested validation that keeps preprocessing, feature fitting, and model selection inside the training folds. This analysis separates gains from feature representation from gains due to nonlinear classification, and relates both comparisons to …

The Grasshopper's Journey To The Bloch Sphere, David Llamas

Graduate Doctoral Dissertations

The Grasshopper Problem asks a simple geometric question. A grasshopper lands on a lawn of fixed area and jumps a fixed distance in a random direction. What shape of lawn maximizes the probability that the grasshopper remains on the lawn after jumping? The jump rule is rotationally symmetric, but the best lawns do not have to be. This dissertation studies how that symmetry breaking occurs, maps the continuum problem to a novel constrained spin system, and uses the spherical Grasshopper Problem to compare quantum singlet correlations with classical local models.

For planar lawns, boundary-integral and perturbative calculations explain why the …

Gendered Precarity, Informality And Survival Among Cambodian Women Migrants In Thailand, Sokha Eng

Graduate Doctoral Dissertations

Migration scholars have long assumed that women migrant laborers move as individuals, leave family behind, are governed by labor migration policies, and are employed full-time. However, in the context of South-South migration, many workers migrate as families, with husbands, wives, and sometimes even children. Some engage in the informal economy, serving as casual and on-call workers. These types of employment fall outside the scope of standard labor migration policies and therefore receive less attention. As a result, migrants’ experiences in such work arrangements remain underexplored. This study examines the experiences of Cambodian migrant women in Thailand by examining the case …

Redesigning Quantum Theory, Matthew Weiss

Graduate Doctoral Dissertations

QBism understands quantum mechanics to be probability theory supplemented by additional nonclassical coherence conditions. In this dissertation, we develop these nonclassical coherence conditions from first principles, emphasizing the role of a well chosen reference measurement. After treating standard probability on subjective Bayesian lines, we demonstrate an equivalence between the QBist approach and the existing framework of generalized probabilistic theories. We show that the fundamental nonclassical coherence relation may almost always be taken to be a gentle modification of the law of total probability, and give a coherentist account of when an experimental scenario has a classical explanation. Finally, we show …

Traversing The Broken Staircase: The Experiences Of Academic Neglect For Black & Brown First-Generation College Students, Kashmeel D. Mckoena

Graduate Doctoral Dissertations

Although Black and Brown students are diversifying college campuses and opening doors for their families as new cohorts of first-generation collegians, they often find themselves silently dealing with the aftermath of academic neglect from U.S. secondary education. This phenomenon can be understood from extant literature as absence of reliable guidance, mentorship, resources, and support that help students persist and succeed in their academic goals. Existing explanations of grit and resilience (Duckworth et al., 2007) not only erase the existence and impact of academic neglect, but also mask the creative solutions and compensatory strategies that Black and Brown first-generation college students …

A Statistical Mechanics Approach To Reinforcement Learning, Jacob Adamczyk

Graduate Doctoral Dissertations

Reinforcement learning (RL), the study of optimal decision-making over long timescales in stochastic systems, has recently seen remarkable advances due in large part to the efforts of the deep learning community. RL has witnessed great success in solving problems in video games, robotics, biological control, and language modeling. However, a unified statistical mechanics framework to understand and develop the corresponding algorithms is lacking. To address this issue, we begin by showing that the reinforcement learning problem can be formulated and solved using the tools of statistical mechanics. Drawing on physical principles of free energy minimization and invariance, we address important …

Graduate Doctoral Dissertations

This study provided detailed empirical evidence on social experiences of Chinese international students within a US liberal arts college context through examining their race, culture, gender, social class, and mental health experiences. This study showed that the experiences of Chinese international students in the US higher education institutions are influenced not only by individual adaptation but also by broader social and institutional contexts. First, findings of this study demonstrated that institutional features of liberal arts colleges, such as small campus environment, residential nature, and more interactive opportunities between domestic and Chinese international students, can simultaneously create opportunities for inclusion and …

A Discursive Analysis Of Lesbian And Queer Experiences Of Unwanted Consensual Sex, Sarah E. Swanson

Graduate Doctoral Dissertations

This study drew on a critical discursive psychology (CDP) analytical approach to examine how lesbian and queer participants made sense of unwanted consensual sex (UCS).  The data analysis traced how UCS was constructed on three discursive levels: the construction of UCS across narratives, the interpretive repertoires mobilized (including sexual scripts), and the broader sociocultural discourses that shaped what elements of their experiences were intelligible. Therefore, I sought to understand both how participants drew on familiar heteronormative and queer ways of talking about sex and how various discursive resources shaped how they could construct themselves and others. Data for this research …

Factorial Structure Of A Bilingual Progress Monitoring Tool For Mindfulness Interventions, Andrea V. Molina Palacios

Graduate Doctoral Dissertations

Mindfulness-based interventions (MBIs) are an increasingly popular option for schools to support youth in each of the multi-tiered systems of support (MTSS). MBIs have proven to increase attention, help with emotion regulation, decrease symptoms of anxiety and depression, and overall increase students’ wellbeing with a cost-effective package that makes it affordable for schools to implement. Moreover, MBIs have also proven to be effective for Hispanic youth who are at a higher risk of experiencing low access to mental health care and higher levels of poverty, which puts them at risk for dropping out and having low academic achievement. However, there …

The Anti-Racist Organization? Power, Embodiment, And The Politics Of Becoming, Patricia Tiimah Naya

Graduate Doctoral Dissertations

Why do organizational justice commitments so rarely produce structural transformation, and what happens to the people who take them seriously? This dissertation addresses that question through a longitudinal qualitative study of Aequitas University, a large public urban research institution in the northeastern United States, during a multi-year attempt to become “anti-racist.” Drawing on 129 semi-structured interviews with 115 organizational members, 7 focus group discussions, four years of field observation, and an archival corpus spanning more than a decade of institutional history, the dissertation examines how justice commitments move through organizations over time. Justice commitments do not simply succeed or fail. …

Genomic Based Environmental Health Assessment: Vieques, Puerto Rico, Valeria Hernandez Talavera

Graduate Doctoral Dissertations

From 1941 to 2003, the United States Navy and North Atlantic Treaty Organization (NATO) used Vieques, Puerto Rico, for military training, which led to long-term pollution from metals, organic chemicals, explosives, and per- and polyfluoroalkyl substances (PFAS). While earlier research found these contaminants in the environment and in living organisms, their combined effects on local ecosystems remain poorly understood.

This dissertation used a Genomic-Based Environmental Health Assessment (GEHA) framework to study the ecological risks from past military pollution in Vieques. The approach combined sediment toxicity tests, chemical analysis, gene expression studies, microbial community analysis, and community-based research. The four main …

From Structure To Experiences: How Facility Capacity And Staffing Shape The Adoption And Impact Of Lgbt-Affirming Policies In Long-Term Care, Andrew Alberth

Graduate Doctoral Dissertations

Long-term care (LTC) settings – including nursing homes (NHs) and assisted living facilities (ALFs) – provide necessary care for individuals with extreme health and functioning limitations. Sexual and gender minority (LGBT) older adults report challenges receiving effective, person-centered care LTC. Some LGBT older adults may hide their sexual orientation and gender identity when entering LTC settings or delay seeking needed LTC fearing discrimination from staff and other residents. Furthermore, staff in LTC settings indicate little awareness of LGBT-residents and possess inadequate LGBT-cultural competency necessary for providing person-centered care. Therefore, LGBT-residents LTC experiences remain underexplored in the broader research. Adopting LGBT-affirming …

Identifying Discrete Reappraisals And Examining The Properties Of Cognitive Reappraisal That Predict Emotional Outcomes, Jenny L. Wu

Graduate Doctoral Dissertations

Cognitive reappraisal is widely regarded as an adaptive emotion regulation strategy and a central strategy to promote cognitive change in psychological treatments. However, findings regarding its effectiveness have been inconsistent, potentially due to the tendency to conceptualize reappraisal as a uniform process. The present study sought to adopt a more fine-grained, process-oriented approach by examining variability in how reappraisal is implemented. Specifically, this study investigated (1) the overall effectiveness of cognitive reappraisal, (2) whether the perceived believability of reappraisals predicts emotional outcomes, and (3) whether different types of reappraisals are associated with differences in emotional outcomes. Participants completed a modified …

Solving For X: Centering Black Girls’ Experiences In Mathematics Education, Natasha A. Fortes

Graduate Doctoral Dissertations

Black girls can grow up, attend school, and move through their math classes without ever feeling seen as capable mathematical thinkers. Their teachers may not affirm their brilliance. Their voices may even go unheard. Math classes may not be a space where they can imagine themselves belonging. These experiences do not reflect ability. Instead, they reflect on the conditions in which they are expected to learn. This study centers the voices of Black girls and asks what they deserve from their mathematics education and instructors to develop a mathematics identity. The study is grounded in Black feminist traditions and draws …

Our Claims Matter: Latin American Migrants’ Nonviolent And Everyday Resistance Across Transnational Spaces, Pryanka Penafiel-Cevallos

Graduate Doctoral Dissertations

This dissertation examines how Latin American migrants engage in nonviolent resistance across transnational spaces in Ecuador, challenging dominant narratives that portray migrants primarily as passive actors or humanitarian subjects. Focusing mainly on Venezuelan, Colombian, and returned Ecuadorian migrants, the study places migrants’ political agency at the center of analysis. It asks how migrants resist, for what purposes, and under which conditions they mobilize nonviolent and everyday resistance practices to claim rights, dignity, and human security in a host country marked by both legal innovation and growing exclusion.

Drawing on civil resistance theory, everyday resistance approaches, and migration scholarship, the research …

Governing Climate Change For Sustainable Food Security In The Busoga Region Of Uganda, James Kintu

Graduate Doctoral Dissertations

Busoga, Uganda's most sugarcane-intensive sub-region, hosts seven mills and an expanding outgrower economy, yet remains among Uganda's most food-insecure areas, with over half of its households food-insecure. This study examined how governance of climate change and sugarcane expansion shapes capabilities for food access, land tenure, and decision-making among women, youth, and land-poor households in Jinja and Buyende.

The study developed an integrated CA-CEP-RFS framework, combining the Capability Approach, Comparative Environmental Politics, and the Resilient Food Systems framework, with Sen's Entitlement Framework bridging capabilities to production, trade, own-labor, and transfer entitlements. A qualitative case study drew on a documentary review, 27 …

Understanding Factors Influencing Multiple Tobacco Product Use Among Adolescents In Thailand: A Structural Equation Modeling Approach, Chaowalit Srisoem

Graduate Doctoral Dissertations

Tobacco use among Thai adolescents is shaped by personal, environmental, and product-related factors. However, the pathways linking these influences to actual behavior remain unclear. This study examined how personal, environmental, and product-related factors, along with intentions to use, relate to tobacco use among Thai adolescents. A cross-sectional secondary analysis was conducted using data from the 2022 Thailand Global Youth Tobacco Survey of 6,235 students aged 13–15 years.
