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 …

Force-Feedback And Load Sharing Mechanisms In Cardiac Myosin Ii Ensembles Revealed By Motor-Specific Perturbations, Omayma Alazzam, Md. Amzadul Hoque Chowdhury, Heath M. Stevens

Faculty and Student Publications

Myosin II motors within ensembles exhibit emergent force-generating behavior that varies based on ensemble size and makeup. However, the mechanisms by which myosins within ensembles sense and modulate behavior due to local and systemic changes in motor behavior, and concomitantly mechanics, remains unclear. To understand how myosin kinetics alter ensemble-level force generation, we employ myosin inotropes, specifically Mavacamten (MAVA) and Omecamtiv Mecarbil (OM), to pointedly alter myosin behavior in a concentration-dependent manner. MAVA has been shown to reduce the number of active myosin heads participating in crossbridge formation and force generation, while OM is recognized for prolonging motor attachment to …

Analysis Of Song Choice At An Anglican Church In The North West, Yvette Wong

Masters Theses

The rise of Contemporary Christian Music (CCM) in the last hundred years has gradually led to the so-called worship wars in the late twentieth century. While scholars (Lester Ruth, Ted Peter, and Vernon Whaley) note that the tension has several fronts, Ruth points out that the most obvious front line of combat in the wars was music on instrumentation, song repertoires between hymns and choruses, and the role of song in corporate worship. To keep the peace, many churches have settled for either one style of service, combined the two in the same service, commonly known as a blended service, …

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 …

Designing Clarity: A Framework For Nonprofit Branding, K. Caitlyn Crissler

Masters Theses

Nonprofit founders and leaders regularly face the challenge of communicating their mission clearly while working with limited budgets, limited design knowledge, and limited access to professional creative support. As a result, many organizations unintentionally waste time, money, and resources on inconsistent visual materials, unclear branding, and inefficient design processes. This thesis investigates how an accessible, streamlined design framework can empower non-designers in the nonprofit sector to make informed visual decisions, collaborate more effectively with designers, and produce communication materials that support their mission rather than hinder it. Utilizing a mixed-method approach , including a literature review of foundational design principles, …

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.

Design And Evaluation Of A Code-Switching-Aware Multilingual Conversational Ai System Using Advanced Rag Architectures, Ashutosh Juvale

Master’s Dissertations

Conversational artificial intelligence has become the primary interface through which hundreds of millions of users in India seek information and customer support. Yet the way these users actually write and speak is fundamentally at odds with the monolingual assumptions baked into most retrieval and generation systems: they code-switch, fluidly mixing one or more of the twenty-two scheduled languages of India with English, frequently typing Indic words in the Roman script ("mera refund kab tak aayega"). Standard Retrieval-Augmented Generation (RAG) pipelines silently fail on such input — the retriever returns off-topic passages because the query and the knowledge base live in …

Telluric Correction Of M-Dwarf Stars Using Machine Learning, Sayak Rana

Master’s Dissertations

The study of M-dwarf stars is of prime scientific interest to us because of their closer habitable zones and the favorable conditions they offer for exoplanet detection. However, telluric contamination of the ground-based spectra results in sharp absorption lines, which makes their study cumbersome. Removing this contamination is necessary for estimating key stellar parameters. The central contribution is a one-dimensional Convolutional Neural Network (CNN) that retrieves the four atmospheric parameters governing telluric absorption: pressure, temperature, humidity, and airmass. These predicted parameters are passed to Telfit which produces an estimated telluric spectrum. The observed spectrum is then divided by this estimated …
