Intersecting Inequities: Latinx Access To Mental Health Services, Melissa Thorson

Dissertations

This study examined barriers to mental health service utilization among Latinx populations using data from the 2022 National Survey on Drug Use and Health (NSDUH). Through the theoretical frameworks of Minority Stress Theory and Toxic Stress Theory, the study investigated the relationships between age, language proficiency, socioeconomic status, and mental health service access among different Latinx subgroups. Statistical analyses included chi-square tests, multiple regression, and mediation analyses on a sample of Latinx adults (N = 9,852). Results indicated associations between age and English proficiency (χ² = 145.23, p < .001, Cramer's V = 0.38), with 45% of adults aged 50 and older reporting limited English proficiency. Socioeconomic analysis revealed that 32% of older Latinx adults reported family incomes below $20,000, with insurance status partially mediating the relationship between income and service utilization (indirect effect = 0.15, 95% CI [0.08, 0.23]). differences in utilization rates emerged among Latinx subgroups (F(6, 1243) = 8.76, p < .001, η² = 0.12), with Mexican-origin individuals showing higher utilization (10%) compared to Puerto Rican individuals (2-3%). Age and socioeconomic status demonstrated interaction effects (β = 0.18, p < .01), while language proficiency moderated the relationship between age and service utilization (β = 0.24, p < .001). These findings suggest that barriers to mental health service utilization among Latinx populations are complex and interconnected, requiring multilevel interventions that address linguistic, cultural, and socioeconomic factors simultaneously. Implications for healthcare policy and service delivery are discussed, emphasizing the need for culturally responsive and linguistically appropriate mental health services.

The Interplay Of Accommodation And Oculomotor Vergence Within Young Adults With Binocularly Normal Vision And Typically-Occurring Convergence Insufficiency, Sebastian Fine

Dissertations

Concerted binocular coordination evoking oculomotor and refractive responses to visual stimuli are essential to daily function. Oculomotor dysfunctions can inhibit binocular responses to visually-near stimuli and have high comorbidities to accommodative dysfunctions. Three visual cues for inward (convergent) and outward (divergent) oculomotor movements, when presented concertedly create natural-viewing conditions: disparity- the binocular difference in light cast onto the fovea due to differing ocular perspectives, blur- the acuity of a visual target which stimulates accommodation, and proximal- the perceived distance of a visual stimuli based on size.

This study aims to quantitatively investigate oculomotor vergence and accommodation performances between individuals with …

Towards Explainable Ai On Graph Neural Networks: Xaig, Jiaxing Zhang

Dissertations

In the evolving landscape of artificial intelligence (AI), Graph Neural Networks (GNNs) have garnered growing prominence for their adeptness in processing graph-structured data. Despite this, the interpretability of their predictions often remains elusive. The demand for transparency and explainability in complex prediction models has reached unprecedented levels. To address this, post-hoc instance-level explanation techniques have emerged, aiming to unveil the rationale behind GNN predictions. These techniques endeavor to unearth substructures that elucidate the predictive behavior of trained GNNs.

This dissertation embarks on an exploration of Explainable AI (XAI) technologies within the realm of GNNs. Amid the challenges posed by the …

Reclaiming Data: A Participatory Action Research Study To Empower Educators, Diana Hammond

Dissertations

Abstract

Currently, the day-to-day data collection and analysis work of teachers is often only deemed valuable if it is easily observed and quantitatively recorded. Teachers are asked to produce results with an incomplete set of tools and are then personally blamed — instead of blame being placed on the structural system — when the desired results don’t manifest. This participatory action research (PAR) study challenged the status quo by asking: What if teachers were empowered to expand their definition of data to include the rich, qualitative data at their fingertips, and what if teachers’ experience and intuition were valued instead …

Building A Grounded Theory Of Resilience Among Survivors Of Chronic Ischemic Stroke, Erin Marie Tompkins Doan

Dissertations

Abstract

Stroke is disruptive with elusive recovery and adjustment. Beyond traditional aspects of stroke rehabilitation, literature suggests adjustment to stroke should also include intervention with focus on resilience. A gap exists between conceptualization, theoretical models, and strategies for supporting resilience in persons with chronic ischemic stroke. This three-manuscript dissertation research comprised a scoping literature review, a pilot study, and a phenomenological case study. We employed a convergent mixed methods design in which we implemented and studied outcomes of an adaptive mindfulness intervention. We implemented eight focus groups with eight adults and four individual interviews over 13 months. The Brief Resilience …

The primary researcher positions all participants as co-researchers to explore ways that could improve the …

Leading Through Crisis: San Diego County Schools' Response To The Social Emotional Needs Of All Students, Johana Bielma

Dissertations

The COVID-19 pandemic led to unprecedented school closures, forcing administrators to take decisive action to radically change the educational system. The imperative to switch to remote learning transformed the dynamics of teaching and learning, leading to both immediate and long-term academic and social emotional consequences for all stakeholders. When schools reopened, administrators faced the challenge of reintegrating students into in-person learning while addressing the pandemic’s lasting effects on academics, mental health, and school safety. While academic regression was evident, the extent of students’ emotional struggles was less anticipated. Many students exhibited increased irritability and mental health issues such as depression …

Reimagining Pedagogies Of The Prison Yard: Using Ethnotheatre To Embody Transcarceral Conocimiento, Mabelle Reynoso

Dissertations

Latinxs make up 40% of California's population but account for 45% of the prison population and 47% of the jail population (Sawyer, 2023). Their overrepresentation in carceral custody not only impacts the individual but also affects families and communities by limiting access to social, political, and educational capital and agency. In response to gaps in research specific to the collateral impact, this interdisciplinary arts-based qualitative study highlights the experiences of five formerly incarcerated Latino men who participated in an Arts in Corrections playwriting class during their time in a California state prison. This study foregrounds their knowledge as cuentistas (storytellers), …

Culturally Affirming Independent School Board Governance: Centering The Experiences Of Independent School Board Members Of Color, Christopher S. Dennis Phd

Dissertations

As schools become more diverse, K–12 independent school boards benefit from diversity (Jernigan et al., 2010; Tolbert Smith, 2022). This study examined the narratives of independent school board members of color (BMOC) across the United States’ racialized history of education (Anderson, 1988; Omi & Winant, 2014). The study used a survey (n = 23) and interviews (n = 9) based on Helms’s (1996) racial identity theory and Booth-Bell et al.’s (2021) board governance theory. This multiple case study examined survey responses of BMOC from 17 schools governed by the National Association of Independent Schools (NAIS). Nine respondents were …

Liberatory Love: Exploring Educators’ Perspectives In Alternative Education, Kamala J. Mallipudi

Dissertations

Establishing an operational understanding of love is difficult. The struggle is magnified when attempting to create a shared vision of love across a group of educators. As Freire (1970/2005) and Darder (2011) affirmed, academic success is advanced when educators demonstrate love as part of their praxis. Continuation high schools represent a population of at-promise students who stand to gain much when their educators employ liberatory love practices. This study examined how educators’ perceptions about liberatory love are shifted or formed when they read, discuss, and reflect on the topic with their colleagues. This study drew on critical pedagogy and engaged …

Belonging Is Resistance: Illuminating The Power Of Women Of Color Mid-Level Administrators In Higher Education, Rachelle Ann Martinez

Dissertations

Resistance has long been a mechanism through which the dominant norms of society are challenged in the name of social justice. White supremacy, heteropatriarchy, and neoliberalism make it difficult for institutions of higher education to increase diversity, advance equity, and prioritize inclusion. Although these systems of domination adversely impact the belonging of all campus stakeholders, the experiences of mid-level administrators are relatively overlooked, and feeling undervalued and underappreciated is a top reason for many, especially women and people of color, who leave the profession altogether. This qualitative study utilized narrative inquiry to understand how dominant societal norms adversely impact the …

Latinas In Higher Education: Paving & Weaving Wholeheartedly, Ariela M. Canizal

Dissertations

The deficit model in research has often framed Latinas in higher education through a lens of barriers and challenges, reinforcing stereotypes that depict them as unlikely to succeed in academic spaces. However, Latinas are actively resisting these narratives, weaving their resilience into their stories as they navigate the complexities of higher education, culture, and identity. This study examines how Latina students incorporate cultural background, familial support, and personal agency to thrive academically while challenging systemic obstacles and societal expectations. The research question that guided this study is: In what ways do undergraduate Latina students navigate identity as they experience leadership …

Post Racial Reckoning: Montessori Instructors' Perspectives On Teaching Through An Antibias Antiracist Lens, Jasmine E. Williams

Dissertations

Prior to the racial reckoning of 2020, Montessori teacher education programs (MTEPs) have only narrowly focused on social justice education (Aronson et al., 2020; Bartolomè, 2004; Cook, 2015; Cross, 2005; D’Cruz, 2022; King, 1991). Although MTEPs began to respond differently post-reckoning, support for implementing practices like antibias antiracist (ABAR) instruction was often absent. This study sought to understand how the racial reckoning and efforts to include an ABAR lens impacted the teaching practices of instructors in MTEPs. While ABAR-related studies exist in general teacher education (Blanchard et al., 2018; Madkins & Nazar, 2022; Martinez-Alba, Herrera, & Hersi, 2022), few focus …

Becoming A Beloved Community: A Restorative Reckoning For A Radical Conversion To Transform Discourse In Higher Education, Latasha Tomay Varlack-Butler

Dissertations

This dissertation critically examines the misappropriation of Restorative Justice Discourse (RJD) within three predominantly white institutions (PWIs), analyzing 59 institutional documents through Critical Discourse Analysis, Relational Critical Discourse Analysis, and Rhetorical Criticism (Fairclough, 1995; Vaandering, 2021; van Dijk, 2008). Tribal Colleges and Universities and South African institutions have emerged as exemplars of authentic RJD, countering co-optation within PWIs. The findings demonstrate that RJD as applied in PWIs is framed in ways that attenuate its transformative potential, perpetuating color-evasiveness (Bonilla-Silva, 2017) and obscuring the intersectional experiences of Black, Indigenous, and disabled communities (Crenshaw, 1991; Million, 2009).

Grounded in decolonial praxis (Smith, …

Dying Young, Brianne L. Overton

Dissertations

Death, often perceived as a disruption to daily life, is an inevitable part of the human experience. While older adults may develop familiarity with mortality through the collective experience of personal and familial losses, young adults generally have limited exposure to death. Despite this, young adults, defined as individuals aged 20 to 34, represent approximately 20% of the U.S. population (U.S. Census Bureau, 2020), and the mortality rate within this age group has been rising over the past decade (Woolf & Schoomaker, 2019). Death among young adults is often overlooked in societal narratives and medical research, which primarily focus on …

Unschoolers In Higher Education: A Narrative Case Study Of Unschoolers’ Sense Of Belonging At University, Melissa Marie Carlson

Dissertations

Approximately 20% of families engaged in homeschooling have selected unschooling as their educational approach, with estimates suggesting this number may be even higher (Vesneski et al., 2022). Unschooling emphasizes the establishment of an environment where children can autonomously direct their learning by exploring their interests, unencumbered by traditional educational milestones or specific schedules (Arnall, 2018; Riley, 2020; Riley & Gray, 2015). Despite increasing public acceptance and recognition, research on the outcomes for unschoolers—particularly those pursuing higher education—is limited (Riley, 2020). The purpose of this study was to explore the importance of supporting unschoolers after they have matriculated, specifically fostering sense …

Does Universal Screening Increase The Proportion Of Culturally, Linguistically, And Economically Diverse Students In Gifted Education?, Leona Alexander

Dissertations

The purpose of this quantitative study was to examine the impact of implementing a universal cognitive screening tool on the proportional representation of culturally, linguistically, and economically diverse (CLED) first-grade students in Gifted and Talented Education (GATE) programs. This study employed a comparative interrupted time series design utilizing a difference-in-differences (DiD) regression model along with additional statistical analyses (two-proportions z-tests and Mann-Whitney U tests) due to limitations in the sample sizes.

Participants included first-grade students (N=425) from two demographically and socioeconomically similar districts in a Rocky Mountain region. One district implemented the universal screener (intervention group n=368), and the other …
