Law Enforcement Officer Performance, Education, And Risk For Suicide, April James Mccommon

Walden Dissertations and Doctoral Studies

Police suicide has been a largely under-researched topic with a small number of quantitative studies- that limit the exploration of potential causals models in the literature. This restricts current scholarly explanations behind officer suicide, furtheradding barriers to adequate prevention and detection. This study was focused on possible explanations behind police suicide, using Zhang's strain theory of suicide and Joiner's interpersonal-psychological theory of suicide to explain the variables used in the model. Using a moderation model, the research question asked to what extent an officer's education level affects the relationship between levels of police officer misconduct and risk for suicide. This …

Minorities' Perception Of The Comprehensive Emergency Management Model Of Distributing Of Information, Lawrence Davis

Walden Dissertations and Doctoral Studies

Failure to receive critical and timely information from emergency management professionals (EMPs) may lead to the loss of life during disasters and emergencies. Recent research and government reports have indicated that there may be communication failures between EMPs and minority community members, though little is known about how minority communities perceive EMP communication efforts. The central research questions and purpose of this study were designed to explore the experiences of minority community members in receiving and interpreting disaster-related communications from EMPs. Data for this phenomenological study were acquired through-in-depth interviews with 13 African Americans (7 males and 6 females) located …

Ceo Duality And Performance Of Not-For-Profit Hospitals, Anh Ngoc Pham

Walden Dissertations and Doctoral Studies

Depending on their needs for enhancing and sustaining their business and market values, some firms choose to operate with a corporate governance structure of CEO duality, in which an executive serves as the CEO and the chairperson of the board of directors. The problem addressed in this study is that past empirical and theoretical studies of the relationship between CEO duality and firm performance of organizations across different industries have generated ambiguous results, and no studies have focused specifically on the relationship between CEO duality and financial performance of not-for-profit hospitals. Based on agency and stewardship theories, and considering that …

Care Transition Gaps: Risk Identification And Intervention, Michael Howard Jongsma

Walden Dissertations and Doctoral Studies

Hospital readmissions related to chronic heart failure (CHF) are costly, widespread, and often avoidable. Patient education that includes diagnosis, causes, medications, diet, exercise, and exacerbation warning signs has been shown to reduce the number of CHF readmissions. The purpose of this study was to use risk stratification to identify CHF patients at high risk for 30-day readmission. Once a high-risk CHF patient was identified, nursing interventions would be triggered to reduce readmissions and close the gaps in the continuum of care following acute care admission. Transitions of care theory was used as the framework for this project. The methodology had …

Teacher Perceptions Of Elementary Children's Internalizing Symptoms When Experiencing Parental Wartime Military Deployment, Letitia Henson

Walden Dissertations and Doctoral Studies

As tours lengthen and deployments of military parents become more frequent, the possible negative effects on the children increase proportionally. This quantitative, comparative study evaluated internalizing symptoms among 220 young children who had a parent currently on military deployment and a parent who returned from military deployment compared to a control group of same age peers whose parents were nonmilitary. Using the theoretical frameworks of attachment theory and ambiguous loss theory, the study investigated 3 internalizing symptoms: Anxiety/Depressed, Withdrawn/Depressed behaviors, and Somatic Complaints among …

Predictors Of Knowledge Of Stroke And Intent To Call 911 Among African Americans, Hyacinth Idu Hyacinth

Walden Dissertations and Doctoral Studies

Stroke is associated with significant health disparity and predominantly affects the elderly. Stroke outcome is significantly improved if an individual is able to get "clot-bursting" medication. A significant predictor of an on-time arrival to the emergency room for treatment in the event of a stroke is the ability to accurately recognize stroke signs and symptoms. The purpose of this study was to determine the factors (demographic, socioeconomic, and educational) that predict the knowledge of stroke signs/symptoms and intent to call 911 in the event of a stroke. The study was grounded in the social ecological theoretical model and analyzed archived …

Self-Efficacy, Cultural Competence, And Perception Of Learning Environment In Traditional And Interprofessional Education Physical Therapy Curricula, Laura Smith

Walden Dissertations and Doctoral Studies

Interprofessional education (IPE), a concept that brings students from different health care professions together in the learning process, has been adopted by some physical therapy (PT) schools as an alternative to traditional PT-only curricula. Both approaches have the goal of improving patient outcomes for an increasingly diverse population. There was a void in the research comparing IPE and traditional curricula in PT education. Grounded in the theoretical frameworks of adult and social learning theory, the purpose of this study was to examine differences in students' self-efficacy, cultural competence, and perceptions of the learning environment based on curricular type and prior …

Diffusion Of Electronic Health Records In Rural Primary Care Clinics, Patricia Lynn Mason

Walden Dissertations and Doctoral Studies

By the end of 2015, Medicare-eligible physicians at primary care practices (PCP) who do not use an electronic health record (EHR) system will incur stiff penalties if they fail to meet the deadline for using EHRs. Yet, less than 30% of rural primary clinics have fully functional EHR systems. The purpose of this phenomenology study was to explore rural primary care physicians and physician assistants' experiences regarding overcoming barriers to implementing EHRs. Complex adaptive systems formed the conceptual framework for this study. Data were collected through face-to-face interviews with a purposeful sample of 21 physicians and physician assistants across 2 …

Knowledge Of Overdiagnosis And The Decision To Participate In Breast Cancer Screening, Kimberly T. Nembhard

Walden Dissertations and Doctoral Studies

In 2014, breast cancer was the second leading cause of death among Canadian women, with women over age 50 years making up 82% of the identified cases. To address this issue, the Ontario Breast Screening Program developed a media campaign that promoted the benefits of mammogram screening, but not the associated risks (i.e., false-positive, false-negative, radiation exposure, and overdiagnosis). This study was designed to determine whether there was a statistically significant relationship between knowledge of overdiagnosis and participation in mammogram screening. This cross-sectional, correlational study used schema theory supported by the effective health communication model. Forty-one women were invited to …

Racial Differences In The Impact Of A Worksite Wellness Program On Cardiovascular Biomarkers, Ceabert Joseph Griffith

Walden Dissertations and Doctoral Studies

Cardiovascular disease (CVD) is responsible for approximately 600,000 deaths in the United States each year, with African Americans (AAs) disproportionately affected. Individual-level approaches to reducing CVD remain ineffective, mobilizing a movement that advocates for population-based solutions. Workplace wellness programs (WWPs) have gained considerable traction as a viable strategy for ameliorating CVD burden among workers in general. However, no studies have looked at the efficacy of WWPs in ameliorating CVD specifically among AA employees--a knowledge gap that this investigation aimed to close. Based on the health belief model and the social cognitive theory, this retrospective cohort study used de-identified secondary data …

Implementing Technology For Science Classrooms In São Tomé And Príncipe, Maria Dolores Rodrigues Jardim

Walden Dissertations and Doctoral Studies

This qualitative bounded case study was designed to understand how technology integration in schools could be addressed in a first-wave country. The integration of educational technology in São Tomé and Príncipe (STP), a first-wave agricultural civilization, can narrow the divide between STP and third-wave information age societies. The conceptual framework was based on theories of change, learning, and context. Toffler’s wave theory described how societies changed while Fullan’s change theory examined how the people might change. Roger’s diffusion of innovations addressed how processes change. Bandura, Vygotsky, and Siemen provided the framework for the learning within the model of change. Finally, …

To address …

Recent Graduates' Perspective On The Efficacy Of Nursing Simulation Laboratory Experiences, Holli Sowerby

Walden Dissertations and Doctoral Studies

It has become progressively difficult to find suitable clinical placement for nursing students. To help meet this need, local schools of nursing are turning to high-fidelity simulation manikins to substitute for clinical experience. There is a lack of research that explores recently graduated nurses' perceptions about the efficacy of simulation experiences. Guided by the constructivist theory, this qualitative case study identified how recent RN graduates viewed simulation experiences and whether associate's-degree RN program graduates and bachelor's-program RN graduates viewed simulation differently. Nine recent graduates participated in individual face-to-face interviews. The data were coded and grouped into 5 major themes in …

Biopsychosocial Factors That Discriminate Between White Collar Offenders And Business Professionals, Susan Lynn Zukowski

Walden Dissertations and Doctoral Studies

White collar crime is pervasive with a larger financial impact to society than violent or street crime, yet it has been understudied. Violent and street offender research has moved beyond the examination of motive and opportunity to study personality, demographics, sociological influences, and psychological influences on development and criminal behavior; however, the bulk of white collar offender research has focused on greed as a motivator and organizational opportunity. Legislative efforts have attempted to curtail white collar crime, but incidents of crime continue to rise, resulting in a continued need to understand white collar offenders and the influences on offender behavior. …

Support Of Maternity Care Practices To Increase Breastfeeding Among First-Time Mothers, Jessica Strauch

Walden Dissertations and Doctoral Studies

Breastfeeding offers numerous health benefits to both the mother and infant, yet it is not routinely practiced due to a number of internal and external factors that influence the mother's decision. Guided by the social ecological model, the purpose of this study was to examine the effect of required reporting to The Joint Commission on perinatal measures, a proxy measure for maternity care practices, and those professional effects on breastfeeding initiation and exclusivity for first-time mothers. The hypotheses were that the mandatory reporting, and thus an increase in maternity care practices, would increase the initiation of breastfeeding and exclusive breastfeeding …

School Principal Attitudes Toward The Inclusion Of Students With Disabilities, Taleshia Lenshell Chandler

Walden Dissertations and Doctoral Studies

Inclusion is a philosophy and practice of educating students with and without disabilities in the same learning environment. Previous researchers have indicated that principals play a key role in implementing successful and effective inclusive programs. However, there remains a gap in the literature regarding the attitudes of principals and assistant principals toward including students with disabilities at both elementary and secondary school levels. Therefore, the purpose of this nonexperimental, quantitative study, based on transformational leadership theory, was to examine the attitudes of principals toward the inclusion of students with disabilities in general education classrooms. An electronic version of The Principals' …

The Perceptions And Experiences Of General Education Teachers Toward Cotaught Inclusion Classes, Beth Milhoan Feustel

Walden Dissertations and Doctoral Studies

This project study addressed the low rate of general education teachers volunteering to coteach inclusion classes at a large urban high school in southeastern Georgia. This low volunteer rate caused administrators at this school to assign general education teachers, who did not opt in, to coteach inclusion classes. Teachers' efficacy was negatively impacted when they were required to teach classes that they did not volunteer to teach. The model of cooperative teaching advanced by Bauwens, Hourcade, and Friend's work served as the conceptual framework for this intrinsic case study. The purpose of the study was to examine how general education …

As supported by constructivist theory, the students in this study were encouraged to use prior knowledge and experiences to make new connections between math concepts and business applications. The key research question examined if there was a significant increase in the standardized mathematics test scores of students enrolled in business classes with extended mathematics instruction compared to the standardized test scores of students not enrolled in business …

Technology As A Health Intervention And The Self-Efficacy Of Men, Karen Denise Maxwell

Walden Dissertations and Doctoral Studies

Mortality rates in the United States are higher for men than they are for women as a result of chronic diseases such as heart disease, cancer, and diabetes. Despite these disproportionate rates, few health interventions are targeted to men, and limited knowledge exists regarding the specific components needed to design technology health tools to appeal to men. The purpose of this quantitative study was to examine the relationship between the use of technology health tools and the role of self-efficacy in men and the influence on participation in healthy lifestyle behaviors. A quasi-experimental design was used to analyze data collected …

Elementary School Teachers' Levels Of Concern With Disruptive Student Behaviors In The Classroom, Jacquline Mccaskey

Walden Dissertations and Doctoral Studies

Educators are concerned over disruptive student behavior that diverts teacher attention from instruction to student's negative behavior. The disruptive student is frequently removed from the classroom, decreasing negative behavior but resulting in shorter instructional time for the disruptive student. The purpose of this correlational survey study was to identify teachers' (a) levels of concern for specific disruptive behaviors, (b) methods most frequently used for disruptive behavior, and (c) professional needs related to general classroom and behavior management. The study examined the relationship between teachers' levels of concern regarding specific behaviors and the degree of support needed to manage those behaviors. …

Understanding Presidential Voting Motivation By Factors Of Agency, Sharlene Wilson

Walden Dissertations and Doctoral Studies

The President of the United States sets the tone for policy and has significant power in adopting and implementing policy. Despite this acknowledged power, prior studies, have not examined whether or not agency theory is predictive of voting in U.S. presidential elections. Agency theory is important in the scope of voting behavior as it identifies the relationships which support significance in practicing the activity. This correlational study examined the statistical impact of personal agency, social agency, and sociocultural agency on predictive voting behavior. This study used secondary data originally collected between 1956 and 2008 by the American National Election Study …
