Engaged Scholarship Activities Among Tenure-Track And Tenured Faculty Members, Michelle Christine Watkins Jan 2015

Engaged Scholarship Activities Among Tenure-Track And Tenured Faculty Members, Michelle Christine Watkins

Walden Dissertations and Doctoral Studies

Institutions of higher education are widely known to be places that help solve the problems of society; however, few college professors seem to practice engaged scholarship after receiving tenure. In a time of decreased funding for public higher education institutions and increased competition for students with private institutions, public higher education institutions would do well to maintain their images as community partners. In this regard, public institutions need to know whether engaged scholarship among the professoriate has decreased, why this may be occurring, and how to inspire professors to create positive social change. This qualitative case study applied Frederick Herzberg's …

Positive Psychological Capital, Need Satisfaction, Performance, And Well-Being In Actors And Stunt People, Brian Hite

Walden Dissertations and Doctoral Studies

Positive psychological capital (PsyCap), a second-order construct formed from optimism, hope, resilience, and self-efficacy, has predicted the performance and psychological well-being of a variety of full-time workers, and mediators of the relationships between PsyCap and performance and psychological well-being have rarely been examined. Using self-determination theory, broaden-and-build theory, and the conceptual framework of positive psychology, this study was an exploration of (a) the relationships among PsyCap, (b) basic psychological need satisfaction (i.e., autonomy, competence, relatedness), and (c) psychological well-being and performance using a sample of 103 working actors and stunt people. A serial mediation model was proposed whereby PsyCap predicted …

Influences Of Csi Effect, Daubert Ruling, And Nas Report On Forensic Science Practices, Timothy Patrick Scanlan Jan 2015

Influences Of Csi Effect, Daubert Ruling, And Nas Report On Forensic Science Practices, Timothy Patrick Scanlan

Walden Dissertations and Doctoral Studies

The media exaggerates the capabilities of crime laboratories while it publicizes the wrongdoings of individual forensic scientists. Such portrayals skew the perspectives of jurors and hinder expert witness testimony. Complicating the problem are separate, but related, phenomena that influence how forensic laboratories conduct casework. These phenomena are Cole and Dioso-Villa's conceptualization of the unrealistic expectations of forensic science created by fictional television, known as the CSI Effect; the Daubert ruling on the admissibility of expert testimony; and some federal policy changes as a result of a National Academy of Sciences (NAS) report that impacted requirements for the daily operation of …
