Perceptions Of Role Conflict And Workplace Stress Among Women Working In Two Traditionally Male Professions, Timothy Herley

Walden Dissertations and Doctoral Studies

Role conflict and workplace stress can result in psychological and physical disorders. Research has indicated that societal forces are ingrained concerning how gendered behaviors are manifested in the workplace. However, research has not included women working in male-dominated professions, nor has research examined how stress and role conflict might differ for women in these professions. Understanding the different experiences of women in two distinct professions might illuminate the diversity of experiences in these understudied environments. This quantitative study, based on role-congruity and transactional stress theories, examined and compared women's perceptions of role conflict and stress in 2 male-dominated professions. A …

Police Perceptions And Decision Making Related To Domestic Minors Trafficked Through Prostitution, Donna Sue Belin

Walden Dissertations and Doctoral Studies

In spite of a paradigm shift redefining domestic minors trafficked through prostitution as victims instead of criminal offenders, many police officers experience uncertainty in the way they evaluate the nature of domestic minor sex trafficking (DMST) and assess the culpability status of prostituted minors. This problem often results in revictimizing children and hindering their ability to access needed services. The purpose of this multiple case study was to explore police officers' perceptions of minors engaged in prostitution and derive an understanding of the experiences, beliefs, and values that underlie these perceptions. The study also focused on how these factors influence …

Factors Contributing To Loss Of Nursing Intellectual Capital, Vera Ligia Grover

Walden Dissertations and Doctoral Studies

In a Level II trauma center, experienced nurses are retiring from nursing positions, which is causing an unstable workforce. According to the literature, there are not enough experienced nurses to mentor the new nurses. Evidence suggests that experienced nurses are associated with improved patient outcomes and that experienced nurse mentors can improve the work environment for less experienced nurses. Focusing on Watson's theoretical framework of caring and Covell's theoretical framework of intellectual capital, this phenomenological study explored the lived experiences of a small group of nurses. Five nurses with 15 years of experience and who had served as mentors were …
