Determinants Of Prostate Survival In Arizona: Demographic And Clinical Characteristics, Gudeta D. Fufaa Dec 2011

Determinants Of Prostate Survival In Arizona: Demographic And Clinical Characteristics, Gudeta D. Fufaa

Journal of Social, Behavioral, and Health Sciences

In investigating the determinants of survival of prostate cancer cohorts, characterization of the cohort in terms of competing underlying causes of death would be appropriate. Atherosclerotic heart disease, bronchitis, acute myocardial infarction, chronic obstructive pulmonary disease, atherosclerotic cardiovascular disease, and stroke were found to be the major causes of death among prostate cancer cohorts aside from prostate cancer. A population-based assessment of the codeterminants of mortality and a demographic and clinical determinant of prostate cancer survival was undertaken. Average survival time and survival curves of the various age categories were significantly different. The average survival time and survival curves of …

Using the behavioral model …


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, …

Transformational Leadership Influence On Rapid Organizational Change In Procter And Gamble Global Manufacturing Operation, Timothy M. Williams Sr.

Walden Dissertations and Doctoral Studies

Most companies lack the ability to implement organizational change; over 70% of Organization Change Initiatives (OCIs) fail. This inability has negative economic and survival implications for companies. OCIs must be effective and rapid to match the high pace of change in the business environment. Transformational leadership (TL) has been linked to successful OCIs through its positive influence on employee commitment and reduced resistance to change, yet little research has been done to identify its association with OCI implementation speed. This study tested TL and change theory and their association with change implementation. It sought to determine if a relationship exists …

Improving The Detection Of Narcissistic Transformational Leaders With The Multifactor Leadership Questionnaire: An Item Response Theory Analysis, Dale Frederick Hosking Martin

Walden Dissertations and Doctoral Studies

Narcissistic transformation leaders have inflicted severe physical, psychological, and financial damage on individuals, institutions, and society. Multifactor Leadership Questionnaire (MLQ) has shown promise for early detection of narcissistic leadership tendencies, but selection criteria have not been established. The purpose of this quantitative research was to determine if item response theory (IRT) could advance the detection of narcissistic leadership tendencies using an item-level analysis of the 20 transformational leadership items of the MLQ. Three archival samples of subordinates from Israeli corporate and athletic organizations were combined (N = 1,703) to assess IRT data assumptions, comparative fit of competing IRT models, item …


Care Coordination, Family-Centered Care And Functional Ability In Children With Special Health Care Needs In The United States, Madeline Marti-Morales Jan 2011

Care Coordination, Family-Centered Care And Functional Ability In Children With Special Health Care Needs In The United States, Madeline Marti-Morales

Walden Dissertations and Doctoral Studies

Children with special health care needs (CSHCN) generally have physical, mental, or emotional conditions that require a broader range and greater quantity of health and related services compared to typical children. Care coordination (CC) and family-centered care (FCC) are necessary in the quality of health care for CSHCN. A gap exists in the literature regarding the impact of CC and FCC on children's functional ability (FA). Previous researchers have focused on met and unmet health care needs, but not on health outcomes or functionality. The purpose of this study was to determine if there was an association between CC, FCC, …

A Synthesized Model Of Compliance Based On Physician And Patient Reported Barriers To Hypertension Guidelines, Pamela Ballou-Nelson Jan 2011

A Synthesized Model Of Compliance Based On Physician And Patient Reported Barriers To Hypertension Guidelines, Pamela Ballou-Nelson

Walden Dissertations and Doctoral Studies

Hypertension affects as many as 50-70 million Americans; early and consistent compliance to hypertension guidelines is important to prevent heart attack and stroke, both leading causes of death in the United States. Despite the advances in medicine and health-care technology, the effectiveness with which hypertension is managed at the individual and community level is less than optimal. The research questions in this study addressed the lack of physician compliance to hypertension guidelines and why patients fail to follow guidelines. Improving hypertension management depends on bridging the gap between physician awareness of evidence-based guidelines and patient compliance. Grounded theory was used …

A Test Of An Evolutionary Theory Of Adiposity Gain Induced By Long Sleep In Descendants Of European Hunter-Gatherers, Oleksiy Chadyuk Jan 2011

A Test Of An Evolutionary Theory Of Adiposity Gain Induced By Long Sleep In Descendants Of European Hunter-Gatherers, Oleksiy Chadyuk

Walden Dissertations and Doctoral Studies

Researchers have identified inadequate sleep duration as one of the factors contributing to global obesity. The purpose of this study was to test a hypothesis deduced from a new sleep-duration-based evolutionary theory claiming that sleep extension in response to lengthening night duration in early fall evolved into a behavioral marker of an approaching winter; this adaptive trait was theorized to produce adiposity gain in White men in response to sleep extension. The hypothesis was that White Americans would show a greater increase in the age-adjusted fat mass index per unit of sleep duration compared to that of Black Americans. Data …


Effect Of Political Skill On Perception Of Organizational Politics And Work Withdrawal Among Community College Employees, David John Ross Jan 2011

Effect Of Political Skill On Perception Of Organizational Politics And Work Withdrawal Among Community College Employees, David John Ross

Walden Dissertations and Doctoral Studies

Community college student support services are an important aspect of success among community college students. Theoretical and empirical models of organizational politics and withdrawal guided the expectation that community college employees who perceive their organizations as political may withdrawal from their organization, diminishing the services delivered to students at the institution. A multisite cross-sectional survey design was utilized to gather quantitative data via Survey Monkey from national professional organizations. Two-hundred seventeen usable surveys from community college administrators (executive, mid-level managers, and administrators) were gathered. Data were analyzed via correlation and regression models to examine if political skill reduced or moderated …


Generational Cohort Differences In Types Of Organizational Commitment Among Nurses In Alabama, April Lavette Jones Jan 2011

Generational Cohort Differences In Types Of Organizational Commitment Among Nurses In Alabama, April Lavette Jones

Walden Dissertations and Doctoral Studies

In hospitals in the United States, the ratio of nurses to patients is declining, resulting in an increase in work demands for nurses. Consequently, organizations face challenges with nurses' organizational commitment. Studies have revealed generational differences, as determined by birth year, in employee levels of organizational commitment in a number of organizational settings. However, there is a gap in the literature regarding the impact of generational cohorts on the organizational commitment of nurses. The purpose of this quantitative, nonexperimental, cross-sectional design was to address whether generational cohorts of nurses differed in their levels of organizational commitment, and to investigate whether …
