Assessing The Effectiveness Of An Interval Estimation And A Visual-Spatial Secondary Task As Measures Of Mental Workload During Laparoscopy, Levi Parker Warvel

Psychology Theses & Dissertations

The goal of the present study was to compare two secondary workload tasks, specifically a time interval estimation and visual-spatial task, to determine which of these is most appropriate for the assessment of laparoscopic mental workload. Participants performed a peg transfer task in two conditions: a normal camera angle and a 90° camera angle intended to increase mental workload. Based on multiple resource theory, it was predicted the visual-spatial task would be more sensitive to the workload manipulation than the time estimation task because it draws upon the specific, as opposed to more general, attentional resources required by laparoscopy. Primary …

Effect Of An Adaptive Thinking Training Methodology On Critical Thinking Disposition Using Human Patient Simulators: A Catalyst For Preparing Advanced Nursing Students, Robert Joseph Fitkin Jr.

Teaching & Learning Theses & Dissertations

Critical thinking decision making is the foundation for effective, safe, nursing practice. Nurses have to assess patient issues rapidly regardless of whether it is emotional, psychological, or physical, and then sort through "rapid fire" questions resulting in invisible sorting, discerning, and drawing of conclusions. Doing this "invisible sorting" well requires practice. Nursing education provides practice through preceptors or scenarios-driven human patient simulators to practice critical thinking. This study examines Adaptive Thinking Training Methodology with simulation exercises as a possible catalyst for growth in critical thinking disposition, and help in addressing the preparation-practice gap for novice nurses.

The Effectiveness Of Whole-Body-Vibration Training In Improving Hamstring Flexibility In Physically Active Adults, Megan N. Houston, Victoria Hodson, Kelda K. E. Adams, Johanna M. Hoch

Human Movement Studies & Special Education Faculty Publications

Clinical Scenario: Hamstring tightness is common among physically active individuals. In addition to limiting range of motion and increasing the risk of muscle strain, hamstring tightness contributes to a variety of orthopedic conditions. Therefore, clinicians continue to identify effective methods to increase flexibility. Although hamstring tightness is typically treated with common stretching techniques such as static stretching and proprioceptive neuromuscular facilitation, it has been suggested that whole-body-vibration (WBV) training may improve hamstring flexibility. Clinical Question: Can WBV training, used in isolation or in combination with common stretching protocols or exercise, improve hamstring flexibility in physically active young adults? Summary of …

Outcomes Of Asymmetric Selection Pressure And Larval Dispersal On Evolution Of Disease Resistance: A Metapopulation Modeling Study With Oysters, Daphne M. Munroe, Eric N. Powell, Susan E. Ford, Eileen E. Hofmann, John M. Klinck

CCPO Publications

Marine diseases are a strong selective force that can have important economic and ecological consequences. Larval dispersal patterns, selective mortality and individual growth rates can modulate metapopulation responses to disease pressure. Here, we use a modeling framework that includes distinct populations, connected via larval transport, with varying disease selection pressure and connectivity to examine how these dynamics enhance or inhibit the evolution of disease resistance in metapopulations. Our system, oysters and MSX disease, is one in which disease resistance is highly and demonstrably heritable. Simulations show that under conditions of population isolation (i.e. local retention of larvae) and strong disease …
