Dale M. Brethower 《Performance Improvement Quarterly》1995,8(2):17-39
The mission of human performance technologists, to assure high levels of human performance in organizations, is well established, and usually accomplished through design and implementation of two major products: performance systems and instructional systems. The speed of change in the environments in which HPT is practiced, however, requires frequent analysis of what knowledge and skills are required of HP technologists in pursuit of this goal. This article works backward from results and the products that obtained them, to identify the knowledge, skills, and attitudes that form the critical human performance technology knowledgebase. The author uses an example from our “universal” neighborhood to illustrate seven basic categories of variables influencing organizational performance, and provides examples and non examples of five essential principles of psychology that can help guide HPT practitioners' efforts to design and implement effective systems. 相似文献

This study investigated the convergent and discriminant relationships between a children's life satisfaction measure, the Students' Life Satisfaction Scale (SLSS; Huebner, 1991a), and a widely used self-concept measure, the Piers-Harris Self-Concept Scale (Piers, 1984). Correlational and regression analyses demonstrated stronger relationships between the SLSS and the Piers-Harris Happiness and Satisfaction subscale compared to the other Piers-Harris subscales. The results of a conjoint principal components analysis also revealed predictable overlap between the SLSS and the Piers-Harris Happiness and Satisfaction subscale. Implications for future research are discussed. 相似文献

Twenty fifteen marked the year of assessment for the Millennium Development Goals (MDGs). The MDGs that achieved the greatest success were those where evidence-based practice (EBP) interventions were implemented. The ability to practice evidence-based medicine is grounded in the creation of and access to medical literature that synthesizes research findings. The role that global health literature played in the success of the MDGs demonstrates that medical libraries and librarians have a role to play in achieving the Sustainable Development Goals (SDGs).Librarians can hold capacity-building workshops that provide instruction on how to access evidence-based literature and also train health professionals to conduct synthesis research. Research findings conducted by in-country health professionals are more likely to address issues being faced by local communities and will afford the possibility of obtaining the necessary evidence-based answers that can then be used to implement policies to resolve public health issues identified in the SDGs.This paper discusses how an international team of librarians leveraged funding from a Medical Library Association/Librarians without Borders/Elsevier Foundation/Research4Life grant to hold a capacity-building workshop in Zimbabwe and follow-up online trainings. The workshop focused on accessing evidence-based resources and conducting synthesis research. Outcomes included the creation and policy implementation of evidence-based knowledge products in alignment with local needs and galvanizing a multisectoral group of key individuals who have gone on to collaborate toward the vision of creating a Zimbabwe innovation hub. Looking ahead, such grants can be leveraged to conduct capacity-building to support knowledge translation and other local training needs. 相似文献

Objective:To evaluate the differences in presentation (formatting) of adverse drug reaction (ADR) information within drug monographs in commonly used drug information (DI) mobile device applications.Methods:A cross-sectional analysis of ADR formatting of twenty commonly prescribed oral medications within seven DI mobile applications was performed. Databases were assessed for ADR information, including presence of placebo comparisons, severity of ADR, onset of ADR, formatting of ADRs in percentile (quantitative) format or qualitative format, whether references were used to cite information, and whether ADRs are grouped by organ system. Data was collected by two study investigators and discrepancies were resolved via consensus.Results:The seven DI mobile applications varied significantly on every analyzed ADR variable with the exception of ADR onset, which was absent in all databases. Significant differences were found for variables known to impact clinical judgment such as placebo comparisons and qualitative versus quantitative formatting. Placebo comparisons were most common among monographs in Lexicomp (30%) but were absent among monographs within other applications. Quantitative information was commonly used in most databases but was absent in Epocrates. Qualitative formatting was present in all Epocrates and Micromedex applications but absent in the majority of other applications. Substantial variations were also found in severity and grouping information.Conclusion:Substantial variation in ADR formatting exists among the most common DI mobile applications. These differences may translate into alternative interpretations of medical information and thus impact clinical judgment. Health care librarians and clinicians should consider ADR formatting when choosing between DI applications. 相似文献
