The Experience Of Menopause As Reported By Sedentary Women, April Elizabeth Ann Rietdyk Jan 2011

The Experience Of Menopause As Reported By Sedentary Women, April Elizabeth Ann Rietdyk

Walden Dissertations and Doctoral Studies

Limited research exists on the experiences of sedentary women as they transition through menopause. This gap creates difficulty for public health practitioners as they strive to develop resources, implement programs, or influence policy change at the community level for this group of marginalized women. Keeping women healthy throughout the aging process, including menopause, improves their quality of life and decreases the impact aging has on the health care system. This phenomenological study, through in-depth interviews, provided the opportunity for sedentary women to share their thoughts and experiences of menopause. Thirteen sedentary women between the ages of 40 and 60, experiencing …

Understanding Psychosocial Rehabilitation Workers' Perceptions Of Difficult Psychiatric Situations, James B. Arnold Jan 2011

Understanding Psychosocial Rehabilitation Workers' Perceptions Of Difficult Psychiatric Situations, James B. Arnold

Walden Dissertations and Doctoral Studies

Psychosocial rehabilitation (PSR) is a community-based service that addresses the challenges faced by people diagnosed as having psychiatric disabilities. While working with co workers and clients, PSR workers may harbor perceptions that could lower the effectiveness of their work and hinder recovery by their clients. Although cognitive-behavioral theory has suggested an association, research has not yet connected PSR worker attitudes about psychiatric situations to their feelings and behavior. In this nonexperimental factorial design, 196 PSR workers were surveyed about the frustrations presented by stressful interpersonal job situations using the Psychiatric Situations Scale to identify whether occupation (case workers, residential workers, …

Perceptions Of Recent Male Nursing Graduates Regarding Gender Bias And Gender-Based Educational Barriers, Nancy Spahr

Walden Dissertations and Doctoral Studies

Despite decades of important contributions by male nurses, nursing is still viewed as a feminine profession. Moreover, male nursing students continue to experience gender bias and gender-based educational barriers within schools of nursing. This has led to failure and drop-out rates much higher than those experienced by their female counterparts. The purposes of this quantitative survey study were to (a) explore the relationship between perceived gender bias, gender-based educational barriers within nursing education, and resiliency in recent male nursing graduates; and (b) to identify those gender-based barriers that were considered to be most prevalent and most important.

Socioeconomic Factors Affecting Infant Sleep-Related Deaths, Catherine M. Hogan Jan 2011

Socioeconomic Factors Affecting Infant Sleep-Related Deaths, Catherine M. Hogan

Walden Dissertations and Doctoral Studies

Racial disparity is present in deaths attributed to sudden infant death syndrome (SIDS) and unintentional suffocation. The Back to Sleep Campaign that began in 1994 caused an overall decrease in SIDS rates, but the racial disparity has continued to increase. Researchers have analyzed and described various socio-demographic characteristics of SIDS and infant deaths by unintentional suffocation in urban areas yet have not simultaneously controlled for multiple risk factors that may contribute to racial disparity such as race, poverty, maternal education, and number of children born to each mother (parity). The purpose of this study was to determine if there is …

The Impact Of Company Grade Officer Self-Sacrificial Behavior On Subordinate Assessments Of Leader Charisma, Danjel Bout

Walden Dissertations and Doctoral Studies

Newly commissioned officers in the U.S. Army are taught to lead their soldiers from the front and to voluntarily make personal sacrifices in the service of the nation. Although this facet of military culture is seen as critical to the integrity of the force, there are few research studies describing the impact of leader self-sacrifice in the U.S. Army. Research evolving from the transformational leadership literature indicates that civilian leaders who engage in self-sacrificial behavior are viewed as more charismatic than their counterparts and that this perception is particularly pronounced in crisis situations. The current study extended this research to …

Patient Adherence To Oral Oncolytics, Holly Sansoucie Jan 2011

Patient Adherence To Oral Oncolytics, Holly Sansoucie

Walden Dissertations and Doctoral Studies

Oral oncolytics continue to come to market at an unprecedented pace. Traditionally, chemotherapy was delivered in the controlled environment of the infusion suite; however, with the increasing use of oral oncolytics, the burden of administration and monitoring has shifted to the patients and/or their caregiver. This paradigm shift, from intravenous chemotherapy to oral chemotherapy, has created new challenges in cancer care. Despite the seriousness of their diagnosis, oncology patients are not always adherent to these requirements. Oncology nurses have always taken the lead in patient education, yet that lead has mostly been in the context of intravenous chemotherapy. There is …
