The Complexities Of Female Sexuality: Narratives Of Women Who Have Experienced Both Heterosexual And Same-Sex Marriages, Krista Anne Butland

Walden Dissertations and Doctoral Studies

Due to social stigma, millions of sexual minorities have concealed their true sexual identities by entering into heterosexual relationships and marriages. Eventually, some transition to same-sex relationships and are able to live authentic lives. This latter group had identified as genuinely heterosexual, never questioning their sexuality until a particular time in their lives when same-sex desires spontaneously appeared. The experiences of transitioning from heterosexual to same-sex partners are not well known, particularly for women who have been legally married to both men and women. Diamond's dynamical systems theory for same-sex sexuality and McCarn and Fassinger's lesbian identity formation model provided …

Mortality Salience Effects On Gender Stereotype Attitudes And Sexism, And The Moderating Effect Of Gender Role Conflicts, Gary Evan Leka

Walden Dissertations and Doctoral Studies

Research on existential mortality fears has indicated that death reminders impact individuals at the cognitive and behavioral levels. One way people cope with this threat is through cherishing cultural values that provide life with meaning. However, little research has explored how death reminders impact cultural standards regarding gender. These cultural values often manifest through various means by male and female groups. Guided by terror management theory, which posits that people address threats to their existence by engaging in culturally-sanctioned behaviors to enhance their self-esteem, the purpose of this study was to examine the effect of mortality salience (MS) on male …

Correctional Nurses' Knowledge And Perceptions Of Methicillin-Resistant Staphylococcus Aureus, Deborah Winbush

Walden Dissertations and Doctoral Studies

Since 1999, Methicillin-resistant Staphylococcus aureus (MRSA) outbreaks have occurred in many correctional facilities. Even after the Federal Bureau of Prisons developed clinical practice guidelines on the management of MRSA within correctional facilities, the prevalence of MRSA decreased only insignificantly. Other researchers suggested infection control compliance was equally as important as developing clinical practice guidelines in reducing the incidence of MRSA. Several studies identified the healthcare professionals' nonadherence and inconsistencies to clinical practice guidelines as contributors to MRSA transmission. Accordingly, this project was designed to develop evidence-based recommendations for improving nurse professionals' adherence to MRSA practice guidelines in correctional settings. Using …

Impact Of Computer-Mediated Communication Duration On Adolescent Social Self-Efficacy, Social Anxiety, And Depression, Melaney Laine Davis-Mcshan

Walden Dissertations and Doctoral Studies

Research suggests that Internet and cell phone overuse may result in lower levels of social skills and encourage isolation from peers. Less clear is whether the duration of computer-mediated communication (CMC) influences adolescent perception of their social skills competency or emotional health. This research was guided by the social cognitive theory, which suggests that social self-efficacy (SSE), the belief that they have the skills to engage successfully with others in conversation and social activities, develops from mastery experiences that regulate thought, motivation, and action. This quantitative cross-sectional survey design utilized a convenience sample of 49 adolescents ages 11-19, living in …

A Comparison Of Regional Health Care Structures For Emergency Preparedness, Leslie Porth

Walden Dissertations and Doctoral Studies

Since 2001, increased policy attention and federal funding mechanisms have required more effective disaster response by government actors and private sector organizations, including the health care system. However, there is limited scholarly evidence documenting which structural elements have been associated with efficacious regional coalitions. This study addressed the gap by examining whether the number of different participating disciplines (a proxy for coalition roles), community setting, and prior weather-related disaster declaration influenced the number of activities (a proxy for coalition responsibilities) conducted by the health care coalition. Social network theory was the theoretical lens with which the study results were used …

Secure-Base Caregiving And Adult Attachment Development Within The Client-Psychotherapist Relationship, Dennis A. Weeks

Walden Dissertations and Doctoral Studies

Recent studies have shown significant improvements in the attachment security of adult therapy clients during therapy, supporting Bowlby's theory that such improvement can be influenced by secure-base caregiving provided by mentors such as therapists. However, because these studies did not measure the secure-base variable, its relationship to client attachment development remains unknown. The present study is the first to evaluate that relationship by measuring clients' pre and posttherapy attachment security using the Relationship Scales Questionnaire and therapists' secure-base caregiving using the Client Attachment to Therapist and Working Alliance Inventory, Short Form. Of 21 initially insecure client participants, 17 experienced high …

Exploring Knowledge Management Practices In Service-Based Small Business Enterprises, Orlando Skelton

Walden Dissertations and Doctoral Studies

Small business enterprises (SBEs) are significant contributors to business growth and employment in the United States, but despite governmental support, the failure rate of SBEs is high.
