Assessment Of Vitamin D Levels And Depression Among Adults In The United States, Troy Jean-Luc Owens

Walden Dissertations and Doctoral Studies

Vitamin D is essential to optimizing health; vitamin D deficiency (VDD) can increase risk of hypertension, cardiovascular disease, and insulin resistance. VDD occurs when individuals do not receive sufficient oral intake or obtain adequate sun exposure. Previous researchers indicated there is a relationship between VDD and depression, while others have indicated there is no relationship. The purpose of this study was to examine the relationship between vitamin D levels and depression, and how this relationship might be moderated by an individual's demographic characteristics (gender, age, smoking status, or marital status). This study was a quantitative data analysis of archival data …

The study's design was factorial quasi-experimental; it used a cross sectional survey consisting of a 2 …

The Association Of Gender And Socioeconomic Position With Cardiorespiratory Fitness In Adolescents, Quentin Oliphant

Walden Dissertations and Doctoral Studies

This meta-analysis investigated the association of gender and socioeconomic position with cardiorespiratory fitness in adolescents. Public health professionals know the importance of physical activity level as a modifiable behavior; however, the literature has revealed that more research is needed on the association of sociodemographic variables like gender and socioeconomic position with cardiorespiratory fitness in adolescents. Using the physical fitness and health outcomes conceptual model as a guide, the overall effect sizes across studies were assessed as well as the moderators of study design, sample size, age, and country. A systematic review of literature identified a total of 18 peer-reviewed studies …

Content Analysis Of Archetypal Portrayal Of Females In Picture Books Read In Preschool Classrooms, Karen Lynn Ellefsen

Walden Dissertations and Doctoral Studies

Literature that depicts females in restrictive roles may limit girls' aspirations and success. Previous studies of award-winning books for young children have found gender-stereotypical role portrayal to be common. The purpose of this qualitative content analysis was to identify the archetypal roles assigned to female characters in picture books read aloud by teachers in the preschool classroom. The conceptual framework for this study was derived from feminist theory and Jungian archetypes. Data were collected in the form of teachers' logs of books they read aloud over a 2-week period. Data were analyzed by employing the 3-read method developed by Madsen, …

Relationship Between Community Violence Exposure, Gender, And Social Information Processing, Yvonne Twana Bell

Walden Dissertations and Doctoral Studies

Violent behaviors among adolescents serve as a disruption to many aspects of society. If these behaviors remain uncorrected, there is increased potential for serious self-harm, harm to others, incarceration, and escalation of violence into homicide or suicide. The purpose of this study was to examine the relationship between youth exposure to community violence and adolescents' social information processing underlying aggressive responses, as well as the potential role of gender in moderating this relationship. A sample of 160 male and female 18-year-olds from the Midwestern United States completed an online survey, which included the Things I Have Seen and Heard (TISH) …

Learning Disability Status And Gender As Predictors Of Self-Efficacy., Irene Ekohamen Aikhomu

Walden Dissertations and Doctoral Studies

In the school district under study, students with learning disabilities were

underperforming when compared to students without disabilities. Research has indicated that improved self-efficacy can promote improved student outcomes and that self- efficacy can be taught. Despite this known association, the school district under study has not provided students with such support. The current study addressed ways in which that gap may be attenuated. Guided by the framework of Bandura's theory of self-efficacy and social cognitive theory, the purpose of this study was to explore (a) whether students' perceptions of self-efficacy differed depending on whether or not they had diagnosed …

Racism Vs. Social Capital: A Case Study Of Two Majority Black Communities, Bruce W. Strouble

Walden Dissertations and Doctoral Studies

Several researchers have identified social capital as a means to improve the social sustainability of communities. While there have been many studies investigating the benefits of social capital in homogeneous White communities, few have examined it in Black homogeneous communities. Also, there has been limited research on the influence of racism on social capital in African American communities. In this dissertation a comparative case study was used within a critical race theory framework. The purpose was to explore the role of racial oppression in shaping social capital in majority African American communities. Data were collected from 2 majority Black communities …
