Daily Prebiotic Consumption Of Sweet Potatoes Shifts Abundances Of Key Gut Microbial Taxa Connected To Gut Health, Alexis Gallegos

Electronic Theses and Dissertations Archive

Diet plays a large role in maintaining a healthy gut microbiome, which impacts many aspects of human health. Sweet potatoes contain high levels of resistant starches and dietary fiber which healthy gut microorganisms can metabolize. We tested if daily sweet potato consumption for thirty days shifts gut prokaryotic communities and the phylogenetic diversity of short chain fatty acid (SCFA) functional genes. Selected functional genes are known to be important for human health associated with butyrate and propionate production pathways. To do so, we collected fecal samples from healthy adult volunteers, before and after daily sweet potato consumption and conducted metabarcoding …

Exploring Mental Health Issues And Health-Seeking Behaviors Among Bangladeshi International Students: A Qualitative Study, Md Monir Hossain

Electronic Theses and Dissertations Archive

This qualitative study explores the mental health experiences and help-seeking behaviors of Bangladeshi international graduate students in the United States. Based on in-depth interviews with sixteen students at the University of Memphis, I examine their mental health challenges, coping strategies, and the impact of cultural stigma.

Harnessing Emergent Multiple Scattering Resonances In A Photonic Glass Structure For Photoelectrochemical Energy Conversion, Ashlyn G. Descarpentrie, Robert H. Coridan

Chemistry & Biochemistry Faculty Publications and Presentations

Light trapping nanostructures are often necessary to improve carrier collection yields in semiconductor photoelectrodes with intrinsically poor electron transport. Photonic crystal templates can generate tailorable light trapping via periodic and precise nanostructure, though this is not a scalable strategy for photoelectrochemical (PEC) applications. It is therefore critical to identify alternative mechanisms for light trapping that tolerate disorder. Light trapping in disordered media is generated by the diffusive transport caused by multiple scattering. In some cases, multiple scattering can generate resonances that resemble those observed in photonic crystals. While resonant multiple scattering is a disorder tolerant light trapping mechanism, it is …

Correctional Officers’ Perceptions Of Personal Safety Equipment Effectiveness, Tiffany Haigler-Sion

Walden Dissertations and Doctoral Studies

The United States has the largest correctional system and the highest incarceration rate in the world. Within this system, correctional officers (COs) serve as the primary point of contact with inmates. Existing literature suggests that the nature of inmates’ offenses often influences COs’ perceptions. Moreover, safety equipment plays a critical role in maintaining security within prison environments. Understanding COs’ experiences and perceptions regarding their safety equipment is therefore essential. The research problem is that little is known about COs’ lived experiences with and perceptions of the safety equipment they carry to keep safe from inmate severe assault. The purpose of …

Novice Middle School Music Teachers’ Perspectives On Preservice Preparation In Title I Schools: A Case Study, Christopher M. Burns

Doctoral Dissertations and Projects

Although considerable research addresses the unique needs of middle school learners and teaching music in low-income schools, there are insufficient studies that provide insight and strategies for teaching music in high-needs settings. Likewise, music teacher preparation programs leave gaps in preparation for prospective music educators, unaware of the challenges of teaching middle school music in a high-needs community. Novice music educators experience challenges that are often unaddressed in undergraduate programs. Experienced music educators with advanced degrees can also feel underprepared to teach in low-income schools. Music educator programs lack content that helps prospective music educators become change agents who can …

An Implementation Of Theological Concepts: Bridging The Gap From Childhood To Adult Christian Education, Lajune A. White

Doctoral Dissertations and Projects

New Jerusalem Church has the pleasure of teaching Bible stories in the children’s church and Sunday school. However, after the children age out of these spaces, they do not transition to the adult classes; they sit in the hallways. Suppose they continue this practice after aging out of the children’s classification and do not engage with fellow believers in the discipleship process. Will they remain connected to their faith-based community? The problem is whether their behavior is due to the absence of theological content in the Bible curriculum used to teach them in children’s church and Sunday school. The purpose …
