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.

Land Access As Liberation: A Qualitative Study On Faith, Food, And Farming Of Urban And Rural Black Land Stewards In The United States, Dominique Edwards

Dissertations

Since 1920, Black farmers in the United States have held less than 2% of the nation's farmland, a direct result of race-based discriminatory policies embedded within federal, state, local, and county-level institutions (Daniel, 2013). Structural barriers—ranging from exclusionary lending practices by the U.S. Department of Agriculture (USDA) to the systematic dispossession of land through legal loopholes, heirs’ property laws, and violent racial terror—have contributed to this staggering decline in Black land ownership (Gilbert et al., 2002). The erosion of Black agrarian landholdings intensified in the latter half of the 20th century, as government programs, civil rights legislation, and technological advancements, …

Colloidal Quantum Dots: A Path Toward Making Mid-Wave Infrared Sensing A Ubiquitous Technology, Mohammad Mostafa Al Mahfuz

Dissertations

Reducing the size, weight, power consumption, and cost (SWaP-C) of infrared detectors could make infrared sensing more widely accessible. In the critical mid-wavelength infrared (MWIR) spectral range of 3-5 gm, commercially available detectors are limited by the high costs associated with epitaxial growth and hybridization, as well as the need for cryogenic cooling. These factors restrict their use to defense and space applications.

Colloidal quantum dots present a promising material for overcoming these challenges, with wafer-scale monolithic integration and Auger suppression being the key material capabilities to minimize the sensor's SWaP-C. Infrared sensors based on colloidal quantum dots have been …

Childhood Neuroanatomical Markers Of Familial And Nonfamilial Attention-Deficit/Hyperactivity Disorder, Rahman Baboli

Dissertations

Attention-deficit/hyperactivity disorder (ADHD) is a highly prevalent neurodevelopmental disorder, characterized by developmentally inappropriate levels of inattention, hyperactivity, and impulsivity. Children with family history of ADHD are at an elevated risk of having ADHD as well as a higher risk of persistent ADHD into adulthood, reflecting a source of etiological heterogeneity in ADHD. This heterogeneity in terms of both biological and environmental risk factors may explain differences in neural correlates, outcomes, cognitive, behavioral as well as developmental trajectories. It is therefore critical to understand the influence of having, or not having positive family risk factors on the neuroanatomical structures of the …

On The Design Of A Framework For Large-Scale Exploratory Graph Analytics, Oliver Andres Alvarado Rodriguez

Dissertations

Large-scale exploratory graph analytics merges data science with high-performance computing to extract critical insights from network-representable data. Data scientists routinely analyze data from the natural, social, and computing sciences by representing it as networks, or graphs, where objects become vertices and their relationships become edges. This representation allows data scientists to add graph analytics to their toolbox. However, designing tools for large-scale exploratory graph analytics is challenging due to the complexities of graph algorithms, such as high communication in distributed systems and large memory demands. These challenges can lead to overly complex software, which limits usability and development to a …

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 …

The Role Of Excitatory Neuromodulation In Managing Variability Of Neural System Output, Omar Itani

Black Parents’ Use Of Educational Advocates: Disrupting Structural And Systemic Racism In Education, Fredericka R. Butler Phd

Dissertations

Research indicates that educators’ deficit perceptions of Black students and their families factor into Black student overrepresentation in disciplinary and special education referrals and underrepresentation in advanced coursework (Annamma et al., 2014; Ford et al., 2023). This prevalence of implicit bias is documented, as is the significance of Black parent involvement in their children’s education (Latunde & Clark-Louque, 2016). Black parents’ awareness of educator racism encourages distrust of educators and interferes with cultivating effective home-school relationships that encourage successful student outcomes. School districts offer the services of educational advocates to provide support to parents whose children are referred for special …

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 …
