Advancing Culturally Relevant Mindfulness In Public Health, Marcus Johnson, Candy Ratliff

The Journal of the Research Association of Minority Professors

Mindfulness-based interventions (MBIs) have gained significant traction in public health, education, and clinical settings due to their demonstrated benefits for stress reduction and psychological well-being. However, these interventions often originate from Eurocentric frameworks that insufficiently reflect the cultural, historical, and structural contexts of diverse and historically marginalized communities. This commentary proposes a Culturally Relevant Mindfulness (CRM) framework that centers the lived experiences, healing traditions, and epistemologies of underrepresented populations. Drawing on interdisciplinary literature and critiques of conventional mindfulness models, the article articulates four guiding principles of CRM: cultural identity affirmation, historical consciousness, ancestral integration, and community-centered practice. Rather than merely …

Don't Force Me To Explain: Rethinking Access Outside Of Compulsory Transparency, Rhea Ienni

Dissertations

My dissertation is concerned with better understanding the barriers disabled people encounter while attempting to procure access both at the institutional level, and in their everyday lives. Within disability and accessibility literature, there are many discourses on what disability is and what access means. However, there are few people who explore the harmful consequences of disabled people being forced to “prove” they are disabled to an ableist world to get their basic needs met, and my dissertation intervenes in this gap. Within current US policy, if a disabled person requires access support at the institutional level, they must provide medical …

The Relationship Between Musical Aptitude And Multiple Intelligences In High School Music Students, Rachel Connor

Masters Theses

This quantitative correlational study examines the relationship between musical aptitude, measured by Edwin Gordon’s GIA assessments, and students’ predominant multiple intelligences (MIs), as defined by Howard Gardner. Although MI has been widely researched, little is known about how intelligence strengths relate specifically to musically adept students. High school music students at Fayetteville Christian School in Fayetteville, NC, were first assessed using the GIA to identify those demonstrating musical aptitude. Eligible students then completed the AMI R/ARCH Profile to determine their strongest MI. A correlational analysis examined whether specific intelligence strengths are commonly associated with musical aptitude. Grounded in Gardner’s MI …

Creating Trust: Strengthening Visual Communication Systems For Small Nonprofits, Jennifer R. Wenz

Masters Theses

This study explores how small nonprofits often fail shortly after they are created because of weak design practices and limited access to professional design tools and skills. Large organizations and nonprofits survive because they invest in strong branding, clear messaging, and long-term design strategy. Small nonprofits rely on volunteers with little to no design training which leaves them with inconsistent branding, unclear visual communication, and materials that fail to build the trust they need to survive. This project will examine the gap through research in the nonprofit areas of communication, visual psychology, accessible design systems, and case studies of successful …

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.

Learning In Infants Using Intrinsically Motivated Goal Conditioned Reinforcement Learning, T I Darsan

Master’s Dissertations

Traditional artificial intelligence models learn by passively digesting large datasets. In contrast, human infants discover skills by actively interacting with their bodies and environments without explicit external rewards. This thesis introduces the Composer Architecture, a machine learning framework designed to mimic this autonomous, open-ended development. The Composer architecture operates in a multi-stage loop, the latent model using Contrastive Learning Through Time (CLTT) to compress high-dimensional raw data from visual, proprioceptive, and touch sensors into a low-dimensional space. To preserve data relationships and prevent topological collapse, a Softmax activation forces these latent representations to lie smoothly on a probability simplex. A …

Evaluation Of A Sleep Health Composite: Changes In Sleep Over The Menarcheal Transition Among Girls, Julianna Adornetti

Master's Theses

Sleep undergoes a shift during puberty, increasing the risk for psychological and insomnia symptoms, particularly among girls. However, little research has examined how the onset of menarche may contribute to vulnerability in sleep and psychological functioning. The Sleep Health framework provides a standardized, multidimensional way to conceptualize sleep health (RU-SATED: satisfaction, alertness, timing, efficiency, duration, and regularity). Although prior studies have provided proof-of-concept for assessing sleep health using a composite score (SHc), its measurement properties have yet to be explored. The primary aims of this longitudinal study were to (1) evaluate the factor structure of a sleep health composite, (2) …

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 …
