Can’T Count Or Won’T Count? Embedding Quantitative Methods In Substantive Sociology Curricula: A Quasi-Experiment, Malcolm Williams, Luke Sloan, Sin Yi Cheung, Carole Sutton, Sebastian Stevens, Libby Runham

Peninsula Medical School

This paper reports on a quasi-experiment in which quantitative methods (QM) are embedded within a substantive sociology module. Through measuring student attitudes before and after the intervention alongside control group comparisons, we illustrate the impact that embedding has on the student experience. Our findings are complex and even contradictory. Whilst the experimental group were less likely to be distrustful of statistics and appreciate how QM inform social research, they were also less confident about their statistical abilities, suggesting that through ‘doing’ quantitative sociology the experimental group are exposed to the intricacies of method and their optimism about their own abilities …

Walden Dissertations and Doctoral Studies

The research problem focused on the 11 million Mexican immigrant families in the United States who speak little or no English. Their stated needs for English literacy, socioeconomic and academic success, and the increasing calls for xenophobic legislation throughout the nation indicated a need to investigate alternative pedagogies to compel positive social change through language fluency. In this case study, Mexican immigrant second-language learners and their descendants were asked how they wanted to learn English and if using native culture as a learning tool would help in achieving their literacy goals. Prior researchers had not asked those questions. Three adults …

Servant Leadership And Non Servant Leadership Organization Triple Bottom Line Reporting Outcomes, Lydia M. Daniels

Walden Dissertations and Doctoral Studies

The competitive environment of the 21st century, failure of U.S. companies, and the financial crisis of 2008 have moved leadership expectations to the forefront of research. However, there is a lack of empirical research about organizational reporting outcomes of self-identified servant leadership (SL) organizations compared to self-identified nonservant (non-SL) organizations. Guided by Greenleaf's SL theory, the purpose of this study was to compare information on organizational data for triple bottom line (TBL) reporting outcomes in SL organizations and non-SL organizations. Using causal comparative research design and global reporting initiative data with a sample of 12 organization reports, reporting outcomes were …

The theoretical framework was grounded in Leithwood's core effective principal practices. A 41-item questionnaire from Colorado Education Initiative with a Cronbach's alpha …

Disparities In Arkansas Mandated Immunization Coverage Among Natural Home And Foster-Care Adolescents, Jerome Essono Ngundue

Walden Dissertations and Doctoral Studies

Anecdotal evidence indicated vaccine coverage disparities among foster-care (FCA) and natural-home adolescents (NHA). Arkansas laws require 5 vaccines for school entry (FVSE) to prevent 9 common childhood diseases. The study problem was that Pulaski County, Arkansas adolescent birth cohort (PCABC) immunization rates were low compared to U.S. adolescents for these FVSE. This study examined the extent to which (1) PCABC immunization rates were significantly different from those estimated for U.S. adolescents in 2006–2008, (2) NHA and FCA immunization rates were different in 2003– 2008; (3) sociodemographic variables mediate associations between home of residence (HOR), NHA or FCA, and up to …
