Foodborne Or Pandemic: An Analysis Of The Transmission Of Norovirus-Associated Gastroenteritis And The Role Of Food Handlers, M. S. Dreyfuss
Walden Dissertations and Doctoral Studies
This study examined the strength of association between food workers and food to norovirus in comparison to bacteria associated with foodborne-related gastroenteritis by whether norovirus had a direct (physical evidence), indirect (statistical evidence), or suspect (neither of the two) association with food or food handlers. The Centers for Disease Control and Prevention considers norovirus to cause the largest number of foodborne-related gastroenteritis cases in the United States. The association of norovirus with foodborne outbreaks through its information data collection form focuses on the food worker as the typical source. Yet, many outbreaks are not foodborne in nature. The gap in …

Public education in the United States has experienced an increase in distance-learning (DL) opportunities. Because research has focused on student achievement in post-secondary DL programs, little is known about secondary students' experiences. The purpose of the current study was to explore DL applicability within secondary education. Specific research questions addressed by the concurrent mixed methods nested study included examining students' opinions and experiences in a secondary DL course and determining whether individual learning styles were addressed. Structured interviews, group discussions, and a survey were used to gather data over 2 months from 14 students in grades 9 through 12 participating …
New Teacher Isolation And Its Relationship To Teacher Attrition, David S. Sleppin
New Teacher Isolation And Its Relationship To Teacher Attrition, David S. Sleppin
Walden Dissertations and Doctoral Studies
Studies suggest that many promising new teachers who experience isolation do not reach their full potential and may leave the teaching profession prematurely. Accordingly, the purpose of this study was to explore the relationship between the experience of isolation among new teachers and the potential for teacher attrition in an urban school district in the northeastern U.S. Grounded in constructivist theory, the phenomenological research design examined in-depth interview data collected from 8 new public elementary school teachers with three or less years experience. A coding procedure began by extracting key phrases and statements from the raw data and reduced information …

The Phenomenology Of Self -Injurious Behavior, William Hosmer
The Phenomenology Of Self -Injurious Behavior, William Hosmer
Walden Dissertations and Doctoral Studies
Self-injurious behavior (SIB; e.g., wrist-cutting, burning) is a pervasive coping phenomenon that may be indicative of dysfunctional affect regulation and complex developmental trauma. Previous research findings identify the incidence rate of SIB to be approximately 10% to 15% of the general population with 5% to 10% of those engaging in repetitive or recurring SIB. Other sources identify approximately 2 million individuals active in this behavior within the United States; 70% of those individuals are female. However, limited research has used internet technology as a data gathering tool to access individuals who have engaged in SIB and are apprehensive to participate …

Locus Of Control And Adjustment To Vision Loss Among People With Age Related Macular Degeneration, Delinda Stinnette
Walden Dissertations and Doctoral Studies
People aged 65 and older account for 12.8% of the population and for 30% of all visually impaired individuals. Age-related Macular Degeneration (ARMD) has been identified as a significant public health issue, with a potential 8 million Americans at risk. While the literature supports a connection between LOC and adaptation to ARMD, there is a gap in the current literature supporting this relationship even when other factors are controlled (i.e. age, sex, education, type of ARMD, when diagnosed, the use of medical treatments, the use of visual assistance devices, participant engagement in rehabilitation, and depression). The present survey study used …

Social Interest And Self -Efficacy Levels Among High School Volunteer Mentors And Their Non -Mentor Peers: A Comparison Study, Courtney Brewer
Walden Dissertations and Doctoral Studies
This study examined social interest, social self-efficacy, and general self-efficacy levels of high school volunteer mentors and their nonmentor peers. School-based peer mentoring has become a popular method for providing support services to students. While several studies examining mentee outcomes appeared in the past decade, less research has examined characteristics of the high school mentors involved. The choice of variables was grounded in Bandura's Social Learning Theory and Adler's Individual Psychology. Thirty-seven mentors and 32 nonmentors from a suburban New York high school completed the Social Interest Scale and the Self-efficacy Scale. Mentor volunteers scored significantly higher in social self-efficacy …
Social Construction Of Knowledge In A Semiformal, Long -Term Learning Environment: A Qualitative Study, Alycia Harris
Social Construction Of Knowledge In A Semiformal, Long -Term Learning Environment: A Qualitative Study, Alycia Harris
Walden Dissertations and Doctoral Studies
Social learning plays a critical role in cognitive apprenticeship, community of practice, and knowledge production theories. Gunawardena's interaction analysis model, which provides a means of evaluating discourse for social construction of knowledge, is comprised of five phases: (a) sharing and comparing, (b) disagreement, (c) negotiation and co-construction of new knowledge, (d) testing of knew knowledge, and (e) use or phrasing of new knowledge. There is a paucity of research that has empirically explored social construction of knowledge, especially in an extended semiformal asynchronous graduate learning experience. This study explored two research questions: whether social construction of knowledge took place, and …
Leadership As Role And Relationship In Social Dynamics: An Exploratory Study Seeking A Leadership Archetype, Brian W. Bridgeforth
Leadership As Role And Relationship In Social Dynamics: An Exploratory Study Seeking A Leadership Archetype, Brian W. Bridgeforth
Walden Dissertations and Doctoral Studies
Previous research on leadership as archetype considered archetype as metaphor and not as it is understood in other literatures as a collectively accepted and defined role within and across cultures. Archetypical theories are posited as useful because they help us understand universal aspects of human behavior; however, empirical research demonstrating archetypical thinking and behavior remains rare. Accordingly, this phenomenological study investigated whether a leadership archetype exists as a shared cognitive template and if so, what characteristics define it. The theoretical framework used to examine the phenomenon of leadership combined leadership theory, philosophy of the mind, Jungian psychology, social constructionist theory, …
Intrapersonal And Community-Related Influences Of Rural Adolescent Pregnancy: A Mixed-Method Approach, Kimberly Becknel Brodie
Intrapersonal And Community-Related Influences Of Rural Adolescent Pregnancy: A Mixed-Method Approach, Kimberly Becknel Brodie
Walden Dissertations and Doctoral Studies
The majority of data on adolescent pregnancy pertains to urban communities, therefore, the individual and social influences associated with adolescent pregnancy in rural communities have not been extensively explored. The pregnancy rate among adolescent women aged 15 to 19 in rural Vance County, North Carolina, is 113.7 per 1,000, nearly twice the state average. This sequential mixed-method study used the social ecological model to evaluate the intrapersonal and community-related factors associated with adolescent pregnancy in this rural area. A quantitative survey assessed intrapersonal factors, namely sexual health knowledge, sex-related attitudes, and self-esteem in pregnant or parenting and nonpregnant or nonparenting …

The purpose of this concurrent, mixed-method study, which utilizes quasi-experimental and case study approaches, was to address the effectiveness of mandated differentiated instruction in a suburban high school. This study investigated the significant differences in achievement before and after the implementation of differentiation as well as differences in achievement between a school that mandated the use of differentiation and one that did not. The study also investigated strategies used to implement differentiation and student and teacher attitudes toward it. For ninth grade literature …
Evaluating Earnings Management With Derivatives And The Use Of Accounting Accruals: A Quasi Experimental Approach, Margot S. Geagon
Evaluating Earnings Management With Derivatives And The Use Of Accounting Accruals: A Quasi Experimental Approach, Margot S. Geagon
Walden Dissertations and Doctoral Studies
Most companies listed on the S&P 500 index have reported smoothed earnings since the 1990s inspiring questions from regulators about the accuracy of financial statements. In 1998, the Financial Accounting Standards Board issued SFAS No. 133 (Accounting for Derivative Instruments and Hedging Activities) to establish accounting and reporting standards for derivative instruments. In 2002, the Sarbanes-Oxley Act (SOX) was issued to eradicate earnings management activities and improve transparency in financial reporting. Although many studies have been conducted to evaluate changes in reporting requirements, much less is known about the effectiveness of these regulations on earning smoothing with discretionary accruals (DA) …

Survey Study Of The Relationship Between Parents' And Teachers' Perceptions Of What Constitutes Effective School -To -Home Communications, Jill L. Murphy
Walden Dissertations and Doctoral Studies
Even though guidelines at a suburban elementary school in Georgia were in place for teachers regarding frequency and methods of parent communication, it was unclear if these methods were being used consistently and effectively. Research has shown that effective communication increases student achievement, but there is a lack of research examining communication preferences of teachers and parents. Therefore, this study evaluated current practices by comparing parents' and teachers' perceptions of what constitutes effective school-to-home communications. The researcher administered questionnaires to a random sample of teachers and parents of 3rd, 4th, and 5th grade students to compare their perceptions of the …

WISEWOMAN (WW) is a comprehensive program for medically underserved women in South Dakota (SD), aged 30 to 64, which aims to reduce morbidity and mortality from chronic diseases. Screening services include blood total cholesterol, blood pressure and blood glucose, and body mass index (BMI). Lifestyle intervention (LSI) sessions are also offered to address physical activity and nutrition. The purpose of this retrospective longitudinal study was to quantitatively examine whether the combination of LSI's and clinical screenings or clinical screenings alone lead to improvements in blood pressure, blood glucose, total cholesterol, and/or BMI at rescreening 10 to14 months from initial screening. …
Personal And Professional Spirituality: Muslim Social Workers' Perspectives, Cheryl W. El-Amin
Personal And Professional Spirituality: Muslim Social Workers' Perspectives, Cheryl W. El-Amin
Walden Dissertations and Doctoral Studies
Research in the area of religion and spirituality in social work practice is lacking minority practitioner representation. This phenomenological study explored the questions of how American Muslim social workers define and experience the religious/spiritual, and perceive the propriety of integrating either, in practice. Ibn Khaldun and Durkheim, early social theorists, suggested that group feeling and affiliation impact personal and professional perception and decision making. American societal views of Muslims are often negative and uninformed. A group of 15 Muslim practitioners with bachelor's or more advanced degrees in social work were recruited through a survey administered via an Internet survey site. …
Defining The International Accounting Standard Board's Governance Network, Patricia A. Rossman
Defining The International Accounting Standard Board's Governance Network, Patricia A. Rossman
Walden Dissertations and Doctoral Studies
There is little empirical research identifying the structural forces influencing the International Accounting Standards Board (IASB). The purpose of this study was to analyze the structural forces underlying international accounting regulation to contribute insights useable by the public, politicians, and scholars to conceptualize the processes of international accounting regulation. Based on stakeholder theory, legitimacy theory, and social network theory it was posited that this network is rationally created to serve certain stakeholder groups in the face of divergent stakeholder interests. The research questions for this study addressed the organizations which constituted the IASB's governance network, the professional and geographic perspectives …
Andragogy: Does One Size Fit All? A Study To Determine The Applicability Of Andragogical Principles To Adult Learners Of All Ages, Wendy Conaway
Andragogy: Does One Size Fit All? A Study To Determine The Applicability Of Andragogical Principles To Adult Learners Of All Ages, Wendy Conaway
Walden Dissertations and Doctoral Studies
According to Knowles's theory of andragogy, the principles of adult learning are the need to know, self-directedness, the role of experience, intrinsic motivation, and readiness to learn. Whereas references in the andragogical literature have assumed that the principles uniformly apply to adults of all ages, differences between adult age groups may influence the effectiveness of the principles on adult learning. Therefore, the purpose of this study was to investigate which adult age group was most accepting of the principles so that more effective teaching may occur. Three adult age groups, emerging adults (18-25), young adults (26-39), and mature adults (40-59) …
The Lived Experience Of Hiv-Positive Tanzanian Orphans, Carol A. Parker
The Lived Experience Of Hiv-Positive Tanzanian Orphans, Carol A. Parker
Walden Dissertations and Doctoral Studies
The purpose of this investigation was to generate a context- specific model of the lived experience of HIV positive Tanzanian orphans. With the advent of anti-retroviral drugs, Sub-Saharan African populations with high burdens of human immunodeficiency virus (HIV) face annually accumulating increases in the number of HIV positive children, and ultimately adults. Perinatally infected, these children often become orphans while still young. Extended interviews were performed with a purposive sample of 12 HIV infected orphaned children between 9 and 12 years of age. Half of the research participants lived in an orphanage and half were children living with guardians in …
The Intersection Of Punctuated Equilibrium And Leadership Emergence Within The Framework Of Naturalistic Decision Making, Linda Moerschell
The Intersection Of Punctuated Equilibrium And Leadership Emergence Within The Framework Of Naturalistic Decision Making, Linda Moerschell
Walden Dissertations and Doctoral Studies
Punctuated equilibrium, a theory of unexpected and sudden change arising out of evolutionary biology and paleontology, has been applied to decision sciences, physics, organizational theory, and group behavior but never to leadership emergence theories. The purpose of the study was to discover how leadership emerges during a period of punctuated equilibrium, a sudden and unexpected change event, using a naturalistic decision making framework. Thus, the research question probed how leadership emergence could be theoretically modeled in a critical event. This grounded theory study was particularly unique because it drew from, and helped unify the four scientific foundations of complexity science, …

Changing The Negative Behavioral And Development Outcomes To A Toxic Prenatal Environment Through Maternal Education, Angela Eileen Laughlin Lebedev
Walden Dissertations and Doctoral Studies
The purpose of this study was to evaluate the effectiveness of current education materials on changing maternal smoking attitudes. Children are affected by prenatal exposure to tobacco smoke. Although there are educational efforts to discourage pregnant women from smoking, the practice continues in a significant number of pregnancies. New materials, based on current research, were also evaluated for effectiveness. The theoretical framework for this study was adult learning theory presented by Knowles which made the assumption that an individual is shaped by environmental systems, that adult learning is affected by previous knowledge they bring to the learning and that adults …
