Examining The Effects Of Tailored Ergonomic Interventions On Reducing Musculoskeletal Disorders For Taxi Drivers, Amal Youssouf

UNLV Theses, Dissertations, Professional Papers, and Capstones

Taxi drivers are frequently exposed to prolonged sitting, whole-body vibration, limited rest opportunities, and psychosocial stressors, placing them at increased risk for musculoskeletal disorders (MSDs). This can be mitigated with the use of ergonomics, which changes one's environment to match an individual's needs within the context and demands of the job. Although ergonomics is a recognized area of occupational therapy (OT) practice, current research is limited to office-based or computer-related settings, leaving a gap in OT-led ergonomic interventions tailored for professional drivers. This capstone project aimed to determine whether OT-based ergonomic strategies, along with an ergonomic checklist as a guideline …

Read The Fine Print, Kayla Lockwood

UNLV Theses, Dissertations, Professional Papers, and Capstones

read the fine print is a two-floor art installation that investigates how midcentury domestic ideology structured bodies, behavior, and perception through visual, spatial, and material systems. Rather than recreating a home interior, it examines how domestic order was engineered across the United States through color coding, planning diagrams, model environments, controlled decoration, and institutional messaging. The two-floor arrangement mirrors the operation of these systems across registers, moving from overt structures of order to quieter, often obscured consequences. By rendering policy, hierarchy, and expectation materially, the installation invites viewers to consider domesticity as a designed system: a set of practices, forms, …

The Highlander Folk School: Incubator For Grassroots Democracy And Its Impacts On The Southern Civil Rights Movement, Kathleen Mcmichael Goodyear

Electronic Theses & Dissertations

Despite the Highlander Folk School’s having played multiple vital roles in the Southern civil rights movement of the 1950s and 1960s, the general public remains unaware of Highlander, which is largely due to its having been omitted from most U.S. history survey course textbooks and ignored by most mainstream historians. These sources perpetuate the image propagated by the 1960s media that the movement was largely composed of Rev. Dr. Martin Luther King, Jr. and his fellow charismatic Black male ministers leading their flock of followers—but the movement was much more than that. Highlander’s rich history in nurturing Southern grassroots activism …

All Works

Atopic dermatitis (AD) is a multifactorial skin disorder characterized by immune dysregulation, impaired epidermal barrier, and strong microbial imbalance. Although genetic susceptibility and environmental triggers are established AD drivers, growing evidence highlights the gut skin axis as an important but underexplored AD pathogenesis factor. Gut microbiota dysbiosis, loss of short-chain fatty acid (SCFA)-producing bacteria, and altered metabolite profiles, such as tryptophan derivatives and secondary bile acids, have been linked to systemic immune imbalance and skin inflammation. However, the precise mechanism by which gut microbial alterations influence cutaneous immunity remains unclear. This review synthesizes recent advances from clinical and experimental studies …
