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 …

Elementary (K-5) Teachers' Perceptions Of Differentiated Instruction, Christopher Maddox

Walden Dissertations and Doctoral Studies

Differentiated instruction is a pedagogical method used by classroom teachers to enhance student learning. Researchers have described how students benefit from differentiated lessons, but have not explored the relationship between teachers' perceptions of differentiation and student success. This gap is problematic because teachers' instruction directly affects student achievement. The purpose of this hermeneutic phenomenological study was to explore how elementary (K-5) teachers define, familiarize, use, and perceive differentiation. The conceptual framework was rooted from a synthesis of ideas found in current refereed literature, and the educational concepts and constructionist theories of Piaget and Vygotsky. Purposeful sampling identified 12 participants for …

By 2040, 79.7 million older adults will live in the US, and nearly 40% will need nursing home services that are primarily funded by Medicare and Medicaid. Researchers have underscored the importance of leadership in quality healthcare care delivery, suggesting that nursing home administrator turnover could influence resident quality of life, causing ill-health for the residents and preventable medical costs for taxpayers. In spite of the suggested association, little research has specifically examined the role of administrator turnover on resident quality of life. As such, the purpose and central research questions of this case study were designed specifically to address …

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 …
