Conceptualizing social capital and active transportation to school through a social-ecological model
A model, based on social ecological theory, was presented and tested to examine elements thought to influence ATS. A logistic regression analysis was run to determine the odds of students walking or biking based on the influence of each construct within the model. Results indicated that the physical and socio-cultural constructs were directly and significantly related to ATS behavior while the construct of safety had an indirect effect. These findings support the idea that there are several factors that operate within and across different ecological levels to influence the mode of transportation to school. Therefore, programs to promote ATS should involve multi-level strategies. In addition to the physical environment, interventions should address interpersonal relationships within the family, school, and neighborhood.
A critical review of the literature revealed that various holistic review practices have been used by several health professions programs to successfully increase URM enrollment and that organizational culture may be a factor that promotes success. Following this, 2017 Physician Assistant Education Association survey data were analyzed to assess the frequency of holistic review in PA programs and examine its association with URM matriculation. Results from 221 of the 223 PA programs accredited at the time showed that 77.5% used holistic review, and its use modestly correlated with proportion of first-year students identified as ethnic minorities (rs = .20, p < .01). Of particular interest, some programs using holistic review had substantially higher proportions of URM students than others. This finding laid the foundation for a qualitative multiple case study to explore the role of organizational culture as a hypothesized antecedent to effective holistic admissions processes.
Survey study responses were used to select two PA program ‘cases’ that met criteria consistent with a proposed conceptual framework linking organizational culture that values diversity (or ‘diversity culture’) to holistic admissions associated with high URM enrollment. Directed content analysis of data revealed that diversity culture appears to be a strong driver of practices that support enrolling diverse classes of students.
Overall, this mixed methods program of research advances understanding of holistic review, its utility, and the influence of organizational culture. The research generated important insights with ramifications for current practice and future studies within PA and across health professions programs.
