Spatially-Weighted Ethnic Density And Residential Segregation: Effects On Health Status Among Older Mexican Americans, Sung Han Rhew

USF Tampa Graduate Theses and Dissertations

Research suggests that living in communities with high densities of persons from their own ethnic group improves the overall health of older Mexican Americans. One hypothesis is that residing in high ethnic density areas allows characteristics of Mexican culture such as strong social ties and social cohesion, to have a beneficial effect. The majority of investigations focused on ethnic density effects, however, have utilized relatively loose interpretations of what constitutes the appropriate social-geographic area to be studied. Moreover it is not clear how certain dimensions of residential segregation are protective or harmful toward health, particularly when measuring ethnic residential segregation …

An Evaluation Of The Utah First District Mental Health Court: Gauging The Efficacy Of Diverting Offenders Suffering With Serious Mental Illness, Stephen Guy Vangeem

USF Tampa Graduate Theses and Dissertations

The decision to establish a mental health court in Utah's First District was largely a political one prompted by the growing popularity of problem-solving courts throughout the country. Because this motivation was policy-driven and not needs-driven, the court was established without an ongoing data collection schedule. As a result, barring anecdotal evidence from program participants, the current impact of the court on two key goals-- reducing recidivism and increasing community-based treatment contact--is entirely unknown. The current study aims to provide a summative program evaluation of the first sixty-eight months of specialty court operation by (1) estimating basic demographic and clinical …

A Conceptual Analysis Of Perspective Taking In Support Of Socioscientific Reasoning, Sami Kahn

USF Tampa Graduate Theses and Dissertations

Scientific literacy is concerned with the informed citizens' ability to negotiate scientifically-related societal issues. The suite of skills necessary to negotiate these complex issues is referred to as Socioscientific Reasoning (SSR). SSR requires, among other things, perspective-taking abilities in order to consider the multi-faceted nature of these open-ended, debatable socioscientific issues (SSI). Developing interventions and instruments to foster and measure perspective taking in support of SSR is therefore critical to the promotion of functional scientific literacy through both research and practice. Although widely studied in many disciplines, perspective taking is a particularly tangled construct that has been used to describe …
