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.

Predictors Of Full Childhood Immunization Status In Owerri, Nigeria, Osuala Uzor Kelvin

Walden Dissertations and Doctoral Studies

Full (complete) childhood immunization against tuberculosis, poliomyelitis, diphtheria, tetanus, hepatitis B, yellow fever, measles, and the maternal retention of immunization documentation are the most cost-effective interventions against vaccine-preventable childhood diseases.

Using the social ecological model, this study investigated the influence of maternal satisfaction with postnatal services and paternal support on full childhood immunization status; it also examined the association between maternal factors and the maternal retention of immunization documentation in Owerri, Nigeria. The hypotheses were that maternal satisfaction with postnatal services and …

Information Operations Under International Law: A Delphi Study Into The Legal Standing Of Cyber Warfare, Kenneth Gualtier

Walden Dissertations and Doctoral Studies

The ever-growing interconnectivity of industry and infrastructure through cyberspace has increased their vulnerability to cyber attack.

Clinical Significance Of Response Shift In A Spine Interventional Clinical Trial, Robin Carlson

Walden Dissertations and Doctoral Studies

The effectiveness of treatments for degenerative spine conditions, where the primary symptom is back pain, is typically determined using patient-reported quality of life (QoL) measures. However, patients may adjust their internal standards when scoring QoL based on factors other than their health. This response shift phenomenon could confound the interpretation of study data and impact effectiveness conclusions. In the current study, response shift was examined using structural equation modeling (SEM) and previously collected clinical trial data comparing 2 minimally invasive medical devices in lumbar spinal stenosis patients through 1 year postintervention. In subject QoL results, reprioritization shift between 3 months …

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

Walden Dissertations and Doctoral Studies

Military wartime deployment of parents has a powerful and potentially damaging impact on their young children. 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 …

Common Boundaries: Moving Toward Coordinated And Sustainable Planning On The Oneida Reservation, Rebecca M. Webster

Walden Dissertations and Doctoral Studies

Comprehensive planning can help communities engage in purposeful and sustainable land use development. Previous research has indicated that Indian reservations in the United States often face unique roadblocks to these planning efforts: checkerboard patterns of tribal and nontribal ownership, and the presence of both tribal and local governments exercising land use authority within the same shared space. These roadblocks can lead to uncooperative, uncoordinated, or unsustainable development. Despite these noted problems, there remains an important gap in the current literature regarding solutions to overcome these roadblocks. The purpose of this study was to address that gap. Guided by Forester's critical …

The Presence Of Cyberbullying In Rural Middle Schools: Advanced Technology, School Initiatives, And Parent Involvement, Amy Painter

Walden Dissertations and Doctoral Studies

This descriptive study used preexisting student and parent surveys to examine cyberbullying in two rural middle schools. This study was guided by the social dominance theory, which says that individuals establish themselves in social hierarchies, and by the social-ecological framework theory, which suggests that behavior is influenced by many related systems. This study identified the rates of occurrence of methods used for cyberbullying, types of Internet access available, parental awareness, intervention, and resolution of cyberbullying issues. A simple random sample of 162 parents and 213 students completed the survey. Compared to national results, more local students (9.9%) admitted cyberbullying in …

African American Race And Culture And Patients' Perceptions Of Diabetes Health Education, Linda Marie Keenan

Walden Dissertations and Doctoral Studies

African Americans diagnosed with diabetes are less likely to self-manage diabetes-specific modifiable risk factors. As a result, utilization of healthcare services occurs at a greater rate than other racial groups, and thereby incurs higher than expected healthcare costs. This ethnographic study explored the elements of diabetes educational material African Americans in a large city in the southern part of the United States found most useful to facilitate self-management of their disease. Bandura's self-efficacy theory provided the theoretical framework. Research questions addressed the preferred educational content, layout of material, and methods for educational delivery and caregiver support. A purposive sample of …
