Hiv Testing Among Young African American Men Who Have Sex With Men, Tayo B. Awopeju

Walden Dissertations and Doctoral Studies

Young African American men who have sex with men (AAMSM) are at greater risk of being infected with the human immunodeficiency virus (HIV) and less likely to seek HIV testing than are members of other demographic groups. This behavior results in a significant public health threat because young AAMSM with an unrecognized HIV infection are less likely to practice safer sex and, therefore, more likely to pass the infection on to their partners. This study is an examination of the social and personality factors that influence HIV testing rates among young AAMSM, using Aday's model of the social determinants of …

A Comparative Study Of Compliance Among Patients Attending An Opiate Outpatient Treatment Center In Rural Appalachia, Jerry Russell Morris

Walden Dissertations and Doctoral Studies

Adults with an opiate addiction have a higher rate of noncompliance with treatment, which limits its effectiveness and increases the burden of care for society.

Influences Of Csi Effect, Daubert Ruling, And Nas Report On Forensic Science Practices, Timothy Patrick Scanlan

Walden Dissertations and Doctoral Studies

The media exaggerates the capabilities of crime laboratories while it publicizes the wrongdoings of individual forensic scientists. Such portrayals skew the perspectives of jurors and hinder expert witness testimony. Complicating the problem are separate, but related, phenomena that influence how forensic laboratories conduct casework. These phenomena are Cole and Dioso-Villa's conceptualization of the unrealistic expectations of forensic science created by fictional television, known as the CSI Effect; the Daubert ruling on the admissibility of expert testimony; and some federal policy changes as a result of a National Academy of Sciences (NAS) report that impacted requirements for the daily operation of …

Restaurant Revenue Management: Examining Reservation Policy Implications At Fine Dining Restaurants, Nanishka Hernandez

Walden Dissertations and Doctoral Studies

In the restaurant industry, some patrons do not honor their reservations, especially on holidays. Grounded in postpositivism and system theories, the purpose of this comparative study was to examine the impact of implementing a credit card payment policy for fine dining restaurants reservations and no shows after implementation of a credit card guarantee policy at a high-end hotel located in the southeast United States. Data were collected from archival records provided by the hotel executives. According to the results of a Wilcoxon Signed Rank test, there was a statistically significant decrease in the number of no shows, p < .001, after the implementation of the credit card guarantee policy. In a paired sample t-test, there was a statistically significant decrease in the number of reservations, p < .001, after implementation of the credit card guarantee policy. The implications for positive social change include the potential to increase understanding of payment policies as they relate to the restaurant industry. Service industry managers can benefit from implementing payment policies that can vary from specific dates, seasons, and type of services. Customers will also benefit by being able to make reservations not originally possible due to demand. The current study adds to service industry knowledge, increasing the understanding of payment policies as they relate to restaurant industry. Conducting a similar study in other service industries in the future may lead to a better understanding of the nature of policies and customers' traits and behaviors.

Use Of Traditional 3-Hour Lectures In Preparing Students For The Childbearing Clinical Setting, Teresa Pohle

Walden Dissertations and Doctoral Studies

Following completion of a 4-year nursing program, some graduates have difficulty applying theories learned in the classroom to the clinical environment.

Exploring Online Community College Course Completion And A Sense Of School Community, Kathleen Stone

Walden Dissertations and Doctoral Studies

Researchers have found low online course completion rates to be a complex problem in higher education. Meanwhile, theory on adult learners' online persistence highlights the importance of a sense of school community. At the small, rural focus community college (FCC) for this study, general education online course completion rates are lower than the national average. FCC has not addressed the low online course completion rates. Using Rovais' composite persistence model as the conceptual framework, this instrumental case study examined how students' experiences and perceptions of a sense of school community contribute to their ability to complete online general education courses. …
