Statistical Power In Meta-Analysis, Jin Liu

Theses and Dissertations

Statistical power is important in a meta-analysis study, although few studies have examined the performance of simulated power in meta-analysis. The purpose of this study is to inform researchers about statistical power estimation on two sample mean difference test under different situations: (1) the discrepancy between the analytical power and the actual power and (2) the influence of unequal sample size and unbalanced design on the power. Results indicated that there are noticeable discrepancies between the estimated power and actual power under certain conditions. In general, unbalanced design decreases the statistical power in the meta-analysis. Recommendations are provided for researchers …

Does Simulation Improve Nursing Student Knowledge, Skills, And Attitudes In Identifying Delirium Superimposed On Dementia?, Sheryl A. Kelly

Theses and Dissertations

This dissertation is comprised of three manuscripts, to be submitted for publication, exploring the use of simulation in geriatric nursing education. The first manuscript is a literature review. Although, a number of articles exist on the use of simulation in nursing education, there is a paucity of research using simulation emphasizing the care of patients with dementia and delirium as a pedagogical strategy or those using a stringent research design.

The second manuscript provides an overview of two conceptual frameworks (National League for Nursing (NLN)/Jeffries Simulation Framework and situated cognition learning framework) and recommends merging them to guide researchers as …
