Pastors’ Influence On Research-Based Health Programs In Church Settings, Shirley M. Timmons May 2012

Pastors’ Influence On Research-Based Health Programs In Church Settings, Shirley M. Timmons

Journal of Health Disparities Research and Practice

Churches, in the United States, are recognized essential players in addressing our mounting health and social service needs. Yet, even though they implement a relatively large number of programs, few are research-based. Focus groups were conducted with pastors from 11 Baptist churches in a small Southeastern town to explore factors that influence the implementation of research-based health programs. Transcripts were coded for domains resulting in four themes: congregant needs, shared programming ethics, common understanding of programming processes, and care for the church and congregation. Pastors value research and seek church-based programs that enhance the health of congregants. Yet, future study …

Promoting Physical Activity In Low Income African Americans: Project Laps, Dorothy W. Pekmezi, Brooke L. Barbera, Jamie S. Bodenlos, Glenn N. Jones, Phillip J. Brantley

Journal of Health Disparities Research and Practice

Low income African Americans are at increased risk for physical inactivity and related chronic illnesses. Thus, effective interventions are needed to address these health disparities. The current study examined the efficacy of a home-based physical activity intervention among a low income African American sample with high rates of chronic illnesses (obesity, hypertension, diabetes, high cholesterol). Participants (n=214) were randomly assigned to either the home-based physical activity intervention (self-help print materials, five monthly newsletters, two telephone counseling sessions) or an attention control condition, which promoted healthy diet. Results indicated that the intervention did not produce significantly greater increases in physical activity …

Beyond The It Magic Bullet: Hiv Prevention Education And Public Policy, Fay C. Payton May 2012

Beyond The It Magic Bullet: Hiv Prevention Education And Public Policy, Fay C. Payton

Journal of Health Disparities Research and Practice

Analytic applications are vital in the assessments of public health and surveillance as these applications can drive resource allocation, community assessment and public policy. Using a dataset of nearly 90,000 patient hospital encounters, the number of instances with an ICD code of HIV and co-morbidities was identified. Blacks accounted for 75 percent of HIV hospital encounters in the dataset. While business analytic applications informed this study of cross-tabulations and interaction effects among race, age and gender, there appears to be a significant relationship among HIV diagnoses and substance abuse. Payer data is informed by the Healthcare Cost and Utilization Project …


Health Disparities In Kidney Transplantation: An Equity Analysis, Shirley A. Wells May 2012

Health Disparities In Kidney Transplantation: An Equity Analysis, Shirley A. Wells

Journal of Health Disparities Research and Practice

The growing incidence of end stage renal disease along with advances of the past 40 years that have improved the success rate of kidney transplantation have created an unprecedented demand for kidney transplant. Yet, certain racial and ethnic groups and women consistently have longer waiting times and lower rates of transplantation which makes a review of the kidney procurement and transplantation system in view of its equity imperative. Reasons given for these disparities have varied from cultural attitudes and beliefs on the part of patients and health care providers, socioeconomic status, rates of organ donation, and geographic location. The equity …

Differential Effects Of Race And Poverty On Ambulatory Care Sensitive Conditions, Farrukh B. Hakeem, Daniel L. Howard, Timothy S. Carey, Yhenneko J. Taylor

Journal of Health Disparities Research and Practice

This study is a continuation of an earlier study that examined hospitalization rates for ambulatory care sensitive (ACS) conditions, as a proxy for quality of care, and found evidence of a racial disparity among African American and White Medicare beneficiaries. The current study sought to determine whether neighborhood socioeconomic status (SES) explained this disparity. Differences in rates of ACS hospitalizations by race were assessed using Cochran-Mantel Haenszel tests and Poisson regression. Unadjusted rate ratios for ACS hospitalization for African Americans vs. Whites were found to be higher in low poverty areas (rate ratio (RR)=1.13; 95% CI (1.08, 1.17)) than in …

Inflammatory Biomarkers And Subclinical Atherosclerosis In African-American Women With Systemic Lupus Erythematosus (Sle), Edith Williams, Carlos Crespo, Joan Dorn

Journal of Health Disparities Research and Practice

Women with lupus are at increased risk for developing cardiovascular disease (CVD). Previous studies of atherosclerosis in SLE have not been representative of the minority groups most affected by lupus and its complications. Therefore, a study of 41 lupus cases and 83 controls was conducted to investigate the relationship between carotid atherosclerosis and inflammation in African-American women. Participation consisted of a questionnaire, physical examination, fasting blood draw, and ultrasound of the carotid arteries. There were observed differences between cases and controls with regard to carotid intima media thickness (IMT) and traditional cardiovascular risk factors, although few reached statistical significance. Tumor …

Sexual Harassment In Las Vegas, Jonathan Michael Birds May 2012

Sexual Harassment In Las Vegas, Jonathan Michael Birds

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sexual harassment, either "quid pro quo" demands or the creation of a hostile environment harms both success and social confidence (Welsh, 1999). The nature of sexual harassment in an overtly sexual environment like Las Vegas has not yet been explored. The current study primarily analyzed responses from UNLV students who work in Las Vegas. Experiences of and attitudes towards sexual harassment were compared by gender. Finally, experiences of sexual harassment were compared between UNLV students and students at another university.


Troubled Youth: Girls In Gangs, Mark Manny Valentin May 2012

Troubled Youth: Girls In Gangs, Mark Manny Valentin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Girls in gangs have been around since society recognized that there was a gang issue and although there has been an increase in attention paid to gangs in the last few decades, there has been relatively little attention paid to the girls in these gangs. It has only been recently that research has been conducted to explore the reasons behind girls joining gangs and their roles in the gang setting. Generally though, the research on girls in gangs has either been middle school surveys or qualitative studies of girls already in gangs. This research pulled from a population of delinquent …


Defining Neighborhood: Social Disorganization Theory, Official Data, And Community Perceptions, Jeremy Waller May 2012

Defining Neighborhood: Social Disorganization Theory, Official Data, And Community Perceptions, Jeremy Waller

UNLV Theses, Dissertations, Professional Papers, and Capstones

While the theory of social disorganization has been refined through research and critique, data and methods used to measure key concepts related to the theory have largely remained the same. This study examines the extent to which resident perceptions of neighborhoods are reflected similarly in official data provided by the U.S. Census, in terms of both neighborhood boundaries and neighborhood conditions. It consists of a combination of respondent-identified data and official data gathered on neighborhoods, their condition, and crime. Comparisons between perceptual indicators of neighborhood boundary and characteristics and corresponding official data at the block, block group, and Census tracts …


Concordance Of Vocational Interest And Efficacy Of Female College Students Pursuing A Traditional Career Path, Priscilla A. Walton May 2012

Concordance Of Vocational Interest And Efficacy Of Female College Students Pursuing A Traditional Career Path, Priscilla A. Walton

UNLV Theses, Dissertations, Professional Papers, and Capstones

Women make up a considerable portion of the 21st century workforce. Despite the increase in the labor force, the Census Bureau continues to reflect that the majority of women are employed in what are defined as traditionally female occupations (Watson, Quatman & Edler, 2002). Even though the proportion of women in the work force has increased, women continue to be underrepresented in high-paying, high status professions that have been traditionally male dominated (Betz, 1994). Significant research has been devoted to understanding the unique variables which affect women's career choices and behaviors. According to Fitzgerald, Fassinger, and Betz (1995), women's vocational …


Measuring Spillover Effects Of Residential Amenity Improvements Using Spatial Hedonic Approach, Shruti Bishan Tandon May 2012

Measuring Spillover Effects Of Residential Amenity Improvements Using Spatial Hedonic Approach, Shruti Bishan Tandon

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this dissertation is to develop a methodology for the estimation of the appropriate welfare benefits in the presence of spillover externalities. The ability to capture influences of the not so easily observed variables allow spatial lag models to measure the direct and indirect spillover effects. The direct effect measures the value of the property in question and the indirect captures the influences of neighboring properties, through a spatial multiplier effect.

Kim et al. (2003) through a path breaking approach estimated welfare benefits of air quality improvement. Their methodology captured spillover effects of amenity changes that lump both …

From Martyrs To Mothers To Chick In Choos: The Medieval Female Body And American Women's Popular Literature, Gina M. Sully May 2012

From Martyrs To Mothers To Chick In Choos: The Medieval Female Body And American Women's Popular Literature, Gina M. Sully

UNLV Theses, Dissertations, Professional Papers, and Capstones

Placing the generic conventions of medieval hagiography, Nina Baym's insights about nineteenth-century American sentimental fiction's overplot, and contemporary American women's popular literature into tension illuminates some important commonalities. First, biographers of the medieval virgin saints and authors of contemporary American women's popular literature deploy the same overplot that Baym identifies as characteristic of American women's nineteenth-century popular fiction. Second, in order to define feminine virtue and establish the virtue of their protagonists, nineteenth-century and post-millennial American women writers rework the contrastive tropes by which hagiographers establish their heroines' virtue. Third, struggles for ascendance in the domestic realm gesture toward its …


Fortifying The Pipeline: An Exploratory Study Of High School Factors Impacting The Information Literacy Of First-Year College Students, Jennifer L. Fabbi May 2012

Fortifying The Pipeline: An Exploratory Study Of High School Factors Impacting The Information Literacy Of First-Year College Students, Jennifer L. Fabbi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Information literacy—the ability "to recognize when information is needed and have the ability to locate, evaluate, and use effectively the needed information” (American Library Association [ALA], 1989, para. 3)—has been widely and increasingly cited as an essential competency for college success, for the workplace, and for life (Bruce, 1997; Eisenberg, 2008; Fitzgerald, 2004; Johnston & Webber, 2003; National Leadership Council for Liberal Education and America’s Promise, 2007; Obama, 2009; Rader, 2002). Information literacy best practice and standards state that students optimally develop this skill set through immersion in the research process—often and over time—and this proposition is also supported in …

Nuestras Experiencias: A Phenomenological Study Of Latina First Generation Higher Education Graduates, Diana Elizabeth Cruz May 2012

Nuestras Experiencias: A Phenomenological Study Of Latina First Generation Higher Education Graduates, Diana Elizabeth Cruz

UNLV Theses, Dissertations, Professional Papers, and Capstones

A review of the literature indicates that Latinos lag behind White and

African American students in higher education degree attainment. This educational gap is of concern because Latinos are the largest minority group in the United States, and the Latino population is expected to increase in the future. Higher education degree attainment for Latinos is vital because statistics show an undeniable relationship between degree attainment and income level. In order to ensure the economic well being of Latinos, it is important that Latinos persist through university degree programs. The purpose of this qualitative study was to explore the experiences of …


Community Resources And Black Social Action, F Street, A Case Study, Robert Joseph Mckee May 2012

Community Resources And Black Social Action, F Street, A Case Study, Robert Joseph Mckee

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examines the resources employed by the predominantly African American residents of Historic West Las Vegas, Nevada, to protest a street closure in their community. Previous studies of collective social action in the black community have stressed the involvement and resources of the black church. Instead, the residents of this community relied on cultural, social, and economic resources that did not depend heavily on the church. In this ethnographic case study, I combined participant observation, ethnographic interviews, prolonged engagement, photographs, and document analysis. I argue that the resources a community employs in social action can be analyzed using my …


The New American Conservation Movement: New Strategies, Focus And Organizations For The 21st Century, Amy Deanna Northrup May 2012

The New American Conservation Movement: New Strategies, Focus And Organizations For The 21st Century, Amy Deanna Northrup

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation provides evidence of the emergence of a new conservation movement in the United States. The strategic, tactical and organizational approaches of traditional conservation efforts, which began in the early 1900s, have shifted during the last two decades. Specifically, the new conservation movement is characterized by three distinct changes. First, many of the well-established conservation organizations, such as the Sierra Club and National Audubon Society, have largely abandoned their traditional focus on increasing the number of acres preserved; instead more defensive and fragmented forms of conservation now reign. The second change to the conservation movement involves a dramatic expansion …
