As a result of the students' poor performance, the school implemented vocabulary squares strategy instruction to improve vocabulary development. Guided by the theory of constructivism, the purpose of this casual comparative study was to determine if vocabulary squares strategy instruction resulted in greater word mastery for 2nd and 3rd grade Honduran students than …

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 Effect Of Textbook Format On Mental Effort And Time On Task, Antonio Lamar Thomas

Walden Dissertations and Doctoral Studies

The relatively little amount of time that some college students spend reading their textbooks outside of lectures presents a significant threat to their academic success. One possible solution to this problem is the use of digital games as an alternative to outside-of-class textbook reading, but a review of previous research did not reveal much information on their efficacy when compared to traditional textbooks. Using Astin's theory of student engagement as a framework, the purpose of this quantitative causal-comparative study was to determine whether a significant difference in engagement, as indicated by mental effort and time on task, existed for college …

Patient Safety Culture And High Reliability Organizations, Jared D. Padgett

Walden Dissertations and Doctoral Studies

A 1999 evaluation of case studies performed by staff from the Institute of Medicine found that between 40,000 and 98,000 patients died from preventable errors, while 43,598 individuals died in car accidents that year. A 2011 report increased that estimate nearly 10 times. Widespread preventable patient harm still occurs despite an increase in healthcare regulations. High-reliability organization theory has contributed to improved safety and may potentially reverse this trend. This explorative single case study explored how the perceptions and experiences of nursing and respiratory staff affected the successful transition of a healthcare organization into a reliability-seeking organization. Fourteen participants from …

Factors Associated With Tuberculin Skin Test Positivity Prevalence In U.S. Medical Laboratory Microbiologists, Julie Ann West

Walden Dissertations and Doctoral Studies

Prior research has indicated that healthcare personnel (HCP) who work in areas where Mycobacterium tuberculosis poses an occupational hazard are at high risk of tuberculin skin test (TST) positivity and subsequent conversion to active tuberculosis (TB). U.S. medical laboratory microbiologists confront similar hazards but have not been studied outside of the HCP aggregate. The purpose of this study was to fill this gap by examining the relationships between the predictor variables of self-reported history of bacille Calmette-Guerin (BCG) immunization, place of birth, and years of laboratory experience and the outcomes of self-reported lifetime TST positivity, preventive treatment noninitiation, and barriers …

Drug Use And Sexual Risk Behaviors Of Msm With Syphilis In Atlanta, Tarneisha Shantelle Means

Walden Dissertations and Doctoral Studies

Many men who have sex with men (MSM) engage in alcohol and drug use. Drug use, particularly methamphetamines, amyl nitrates (poppers), and drugs used to treat erectile dysfunction among MSM may also contribute to risks such as unprotected sex, which leads to the possibility of contracting syphilis, Human immunodeficiency virus (HIV), and other Sexually Transmitted Infections (STIs). In the Metro Atlanta Area (Fulton and Dekalb Counties), primary and secondary syphilis rates among MSM are still rising and rank highest among the other counties in the area. Guided by the risk and protective factor theory, the purpose of this study was …

Teacher Assessments Of Positive Behavior Support In School, Terrie Davis Phillips

Walden Dissertations and Doctoral Studies
