These topics have not been qualitatively investigated in Mexico. The purpose of this case study was to explore the process involving the social construction of values, perceptions, and conceptions in regard to organized criminal violence and peace possibilities in Mexico.

However, no study was found that investigates this phenomenon. The purpose of this study was to explore the lived experiences of service members with combat-related posttraumatic stress symptoms and the human-animal bond. The study applied a blend of constructivism and phenomenology to …

Increasing Students' Academic Involvement: Chilean Teacher Engagement With Learners In Blended English As A Foreign Language Courses, Christopher P. Johnson

Walden Dissertations and Doctoral Studies

Learning English as a foreign language (EFL), a highly valued skill in the Chilean marketplace, is an arduous and complex personal endeavor requiring high student motivation. Reflecting this challenge is the heightened anxiety among EFL students, whose work has been associated with historically meager results. Blended learning, the fusion of face-to-face and online content delivery and assessment, offers a promising solution to EFL learner reticence. Evidence suggests that an active online teacher presence in a blended EFL course can enhance student engagement. The purpose of this study was to discover the perceptions of EFL instructional specialists concerning (a) student involvement …

Physician Decision Criteria Regarding Omega-3 Dietary Supplements, Warren P. Lesser

Walden Dissertations and Doctoral Studies

American Heart Association officials and other expert cardiologists recommend omega-3 (n-3) dietary supplementation for the secondary prevention of cardiovascular disease, a prevalent health problem in the United States. Physicians' lack of understanding of possible n-3 preventive health benefits results in underprescribing n-3 dietary supplements and lower n-3 dietary supplement product sales. N-3 dietary supplement marketers do not understand physician n-3 prescribing decision criteria enough to optimize high-impact communication to physicians to increase n-3 dietary supplement product use. The purpose of this phenomenological research study was to improve n-3 marketers' understanding of how physicians reach decisions to prescribe or recommend products …
