Teaching Students To Teach Patients: A Theory-Guided Approach, Lori Candela, Linda B. Piacentine, Kathleen L. Bobay, Marianne E. Weiss

College of Nursing Faculty Research and Publications

Nurses in every setting provide patient teaching on a routine basis, often several times a day. Patient teaching skills are essential competencies to be developed during pre-licensure nursing education. While students learn what to teach for specific conditions, they often lack competence in how to teach in ways that individualize and optimize patient learning. The ultimate goal of patient teaching is to arm patients with the knowledge and skills, and the desire and confidence in their ability to reach their targeted health outcomes. We describe the creation of a theoretical framework to guide development of patient teaching skills. The framework, …

Providing Metrics-Based Results To Student Pilots For Critical Phases Of General Aviation Flights, Kelton Karboviak

Theses and Dissertations

This work details the development of the Critical Phase Analysis Tool (CPAT), a tool for analyzing and grading the quality of approach and landing phases of flight for the National General Aviation Flight Information Database (NGAFID). General Aviation (GA) accounts for the highest accident rates in Civil Aviation, and the approach and landing phases are when a majority of these accidents occur. Since GA aircraft typically lack most of the sophisticated technology that exists within Commercial Aviation, detecting phases of flight can be difficult. Moreover, because of the high variability in GA operations and abilities of the pilot, detecting unsafe …

Staphylococcal Enterotoxins G And I Elicit Long-Term Anti-Tumor Responses In Humanized Hla-Dq8Αβ Transgenic Mice, Peter Knopick

Theses and Dissertations

Immunotherapies have evolved into a collection of tools used clinically in the treatment of several pathologies. Staphylococcal enterotoxin G and I are potent T cell activators that drive multifaceted immune responses and have been implicated in antitumor responses. The addition of SEG and SEI as useful immunotherapies could be underappreciated as mice do not respond as humans would to superantigen stimulation. HLA-DQ8 mice with established B16-F10 tumors receiving 50μg each SEG and SEI 6 and 9 days post tumor implant resulted in 80% progression free survival >300 days. In comparison, allogeneic C57BL/6 mice did not benefit from SEG/SEI therapy. Remarkably, …
