    Extending recent investigations on the structure of Tukey types of ultrafilters on P(ω)\mathcal{P}(\omega) to Boolean algebras in general, we classify the spectra of Tukey types of ultrafilters for several classes of Boolean algebras, including interval algebras, tree algebras, and pseudo-tree algebras.Comment: 18 page

    A Phenomenological Study of the Experiences of Teachers Who Form Positive Relationships With At-Risk Students in Title I Middle Schools in the Southeast

    The purpose of this transcendental phenomenological study was to describe the experiences of teachers who form positive relationships with at-risk students in Title I middle schools. The theory guiding this study was Nel Nodding’s ethic of care as it relates to the teacher as a caregiver interested in the expressed needs of the students. Using a qualitative transcendental phenomenological design, 15 southeastern Title I middle school teachers were selected to participate in the study. The central question guiding this research was: How do teachers describe their experiences of forming positive relationships with at-risk students in Title I middle schools? Sub-questions to further refine the central question were: (a) What perceptions do teachers have about the factors that contribute to building and maintaining positive relationships with at-risk students? (b) How does modeling an ethic of care impact teachers’ relationships with at-risk students? (c) When modeling of an ethic of care, what do teachers perceive as the specific behaviors that help create a sense of security or belonging for at-risk students? Data collection included face to face interviews, a questionnaire, photo narratives, and a focus group. Data analysis used the Moustakas (1994) method for transcendental phenomenological research. This included the epoche, listing significant statements, writing a textural description, structural description, and composite description

    Examining the Relationships between Early Sexual Debut and Social Norms, Sexual Behaviors, and Sexual Violence in Nigerian Girls and Young Women

    Introduction: Nigeria is the most populous country in Africa, with over 186 million residents and 62% under age 25. It is plagued by public health problems disproportionately affecting young females, including prevalence rates of HIV/AIDS and unwanted pregnancy among the highest in the world. The purpose of this study was to (1) examine the association between age at first sex and sexual risk-taking behaviors and sexual abuse and (2) determine whether belief in sex-related social norms moderated those relationships. It extended previous research by exploring age at onset as a determinant and identifying targets for prevention activities to help policymakers and stakeholders prioritize limited resources for appropriate response efforts. Methods: Using data from the Violence Against Children Survey, secondary analysis of 899 Nigerian females aged 13-24 was conducted. The predictor variable of interest was early sexual debut before age 15 (ESD). Outcomes explored were condom use, multiple sex partnership, HIV testing (lifetime and past 12 months), and sexual violence victimization (lifetime and past 12 months). Study covariates included sexual norms, age, marital status, religion, school attendance, ethnicity, and food insecurity. Bivariate and multivariable logistic regression analyses were used to estimate adjusted odds ratios (OR) with 95% confidence intervals (CI). Results: ESD was positively associated with an increased risk of inconsistent condom use (OR=5.2; 95% CI: 1.2 – 23.1) and lifetime HIV testing (OR=2.1; CI: 1.1 – 4.0). Statistically significant interactions were not observed in any of the six hypothesized relationships. Conclusions: Using condoms inconsistently and never being tested for HIV were both more likely among those who debuted sexually before age 15. Endorsing at least one traditional sexual norms belief did not have a moderating effect. However, sex norms were independently associated with inconsistent condom use, not having an HIV test in the past 12 months, having experienced sexual abuse in one’s lifetime, and experiencing sexual violence in the past 12 months. Therefore, prevention programs should be designed to alter sociocultural views of what is deemed acceptable/unacceptable behavior for men and women, promote consistent condom use among girls and young women, and improve access to voluntary HIV testing and counseling

    An exploration of the gendered constructions of ‘stoner’ identity on a Western Cape campus

    Magister Artium - MAThis study employed a social constructionist understanding of ‘identity’ to identify key markers of gendered ‘stoner’ identity and to consider how gendered ‘stoner’ identity is performed on a Western Cape campus. The aim was not simply to consider how they see themselves, but also how they are considered through the lenses and perception of non-smoking students at campus. In trying to understand the gendered experiences of ‘stoners’, this research was grounded in a feminist theoretical perspective and feminist methodological approaches to explore gendered constructions of ‘stoner’ identity at this Western Cape campus. The data for this study was collected through conducting two focus group discussions, and six semi structured, in-depth interviews with six male and six female students from a range of locations across campus. The participants in this study who smoke marijuana/weed did not reject the term ‘stoner’, rather, they claimed this identity, labelling themselves ‘stoners’. My research shows that ‘stoner’ identities both transgress and reinforce normative femininities and masculinities

    Project HEAL (Healthy Eating and Activity for Life): Proposing a Faith-Based Health Education and Lifestyle Intervention for Rural African Americans

    Get PDF
    African Americans, particularly those who reside in rural areas, are at increased risk of developing several preventable health conditions, including type 2 diabetes, cardiovascular disease, and overweight/obesity. Because of several professional and personal experiences, I was inspired to use this thesis as an opportunity to propose an intervention that addresses these preventable health conditions. The proposed intervention, Project HEAL (Healthy Eating and Activity for Life), is a faith-based, theory driven education and comprehensive lifestyle management intervention for rural African Americans. This program is of public health importance because it may be particularly useful in positively impacting the health of rural African Americans, a traditionally hard-to-reach population, and in significantly reducing racial/ethnic and geographic health disparities.Project HEAL is informed by the Social Cognitive Theory and Health Belief Model. These theories were chosen because of their emphasis on self-efficacy, the individual, and the environment. Much of the content of Project HEAL was derived from the curriculum of the evidence-based lifestyle modification intervention of the Diabetes Prevention Program. The Project HEAL curriculum is a modified version that addresses specific constructs of the previously mentioned theories and that is more appropriate for rural African Americans churches and for small group settings. To ensure a comprehensive evaluation of the program, Project HEAL's evaluation strategy will be guided by the Reach, Efficacy, Adoption, and Implementation, and Maintenance framework for health behavior programs.Project HEAL will be implemented with the guidance of an advisory committee and with the help of lay health educators. Therefore, while this thesis describes the Project HEAL development and implementation in detail, there are several aspects of the program will need additional modifications to suit the participating church and its congregants. It is my sincere wish to implement this program to determine its feasibility and translatability to public health policy and research regarding rural African Americans
