The Relationships Among Orthorexia Nervosa, Perfectionist Tendencies And Academic Achievement In Nutrition And Dietetics Students, Sophia Grace Owens

Master's Theses

Eating disorders can cause a disturbance in how the health of food is viewed (Cerniglia et al., 2017). If a person has disturbances in their eating behaviors that can cause harm to their health, but the behaviors do not fit into the criteria of a specific eating disorder, they fall into the category of a disordered eating pattern (Academy of Nutrition and Dietetics, 2018). Because of the stress the college environment can cause students, some college students may cling to anything they can control, which may be reflected in their dietary habits. Orthorexia Nervosa (ON), a disordered eating pattern, is …

"The Way It Comes—Through Nature:" Christian Realism, Rural Landscapes, And Divine Confrontations In Flannery O'Connor's Farm Fiction, Ashton Bailey Thomas

Master's Theses

Flannery O’Connor, though often labeled a Southern Gothic writer, preferred to place herself in the genre of “Christian Realism.” For her, the grotesque nature of her stories’ endings reflects not grace itself but the culmination of repeated rejections of grace. In her essays and letters, O’Connor argues that grace should be depicted “the way it comes—through nature,” equating the spiritual with the natural world. In her stories’ farm landscapes, O’Connor presents an ever-present grace through nature that, though often ignored or rejected, serves as a catalyst for spiritual confrontations. When this grace is continually denied, violence becomes the only force …

Affect, Efficacy, And Protest Intentions: Testing A Multilevel, Dual-Pathway Model Of Collective Action, Blaine G. Robbins, Steven Pfaff, Ross L. Matsueda

Sociology Faculty Articles and Research

What are the consequences of affect and efficacy for protest intentions, and do these consequences stem from personal disposition and/or situational characteristics? Here, we test a dual-pathway model of collective action in which anger and efficacy operate at multiple levels of analysis. To test this model, we administer a factorial survey experiment of student protest to a random sample of undergraduate students (N = 880). We find that the effect of anger on protest intentions follows two routes—one dispositional and one situational—and that the effect of efficacy flows through a situational channel. We also find that anger and efficacy are …

Suprathel Burn Dressing Versus Standard Care: Impact On Hospitalization Duration And Post- Discharge Outpatient Visits, Isaac Awolola

Doctor of Nursing Practice Final Manuscripts

The aim of this evidence-based project is to determine the effectiveness of Suprathel a synthetic, one-time application, wound dressing that acts as a temporary skin substitute, particularly effective for partial-thickness burns and deep dermal burns vs, the standard of either Polysporin or Santyl, Xeroform, gauze on the frequency of outpatient (OP) visits after a patient’s discharge. A secondary aim of this project was to investigate whether Suprathel burn dressing significantly decreases the length of stay (LOS) for patients with second-degree burns involving < 20% total body surface area (TBSA). The results showed that the use of Suprathel dressings resulted in a shorter hospital stay 7.05 vs 9.35 days with a higher number of outpatient visits 5.47 vs 2.69 visits, compared to conventional dressings. The use of Suprathel dressings as a standard practice reduces inpatient hospitalization but increases outpatient visits and resource utilization. The use of Suprathel dressings shortens the length of hospitalization and may augment patient comfort, and decrease overall healthcare costs associated with hospitalization. Due to the reduction in need for painful daily dressing changes, Suprathel dressings constitute a potentially preferred option in burn care and could thereby influence treatment protocols and enhance patient outcomes.

Keywords: Wound care, Suprathel dressing, total body surface area, Outpatient Visits, Second-degree Burn, Length of stay, Gauze
