This study describes a content analysis aimed at identifying the distribution of empirical research strategies and techniques reported in high-profile LIS journal literature published in 2005. For each article, researchers identified the overall research strategy, the data collection technique, and whether the type of analysis was quantitative or qualitative. The taxonomies used in the analysis were those based on Järvelin and Vakkari's [Järvelin, K., & Vakkari, P. (1990). Content analysis of research articles in library and information science. Library & Information Science Research, 12, 395-422] study in order to compare the results with the earlier findings derived from the 1975 and 1985 literature. The survey approach remains the predominant research strategy in both library science and information science. However, there was a marked increase in experimentation. There were more modest increases in the use of qualitative approaches, except for historical research, which showed a marked decline. This study's findings will inform development of methods courses in doctoral programs, which aim to cover the most commonly used strategies and techniques in contemporary LIS research. Revised taxonomies, which include previously unspecified strategies and techniques such as ethnography and transaction log analysis, are suggested for future content analyses of LIS research. 相似文献

An understanding of shaft dynamics during the golf swing was gained through a series of theoretical simulations, using a 3D
forward dynamics model. By resolving the resultant force applied at the grip end of the club into a tangential and a radial
(centripetal) component, the mechanisms of shaft deflection were quantified. It was determined that radial force plays an
important role in producing the toe-down and lead-deflections recorded in all golf swings made with a driver. However, the
simulations also revealed that the recoil of the shaft, from its previously toe-up and lag deflected position during the downswing
(due to tangential forces), plays at least an equally important role in determining the position and orientation of the clubhead
at impact. It was further demonstrated that, due to the influence of the radial force component, maximum kick velocity is
reached after the clubhead has passed beyond the neutral shaft position. 相似文献

In 1965, Lyndon B. Johnson announced that the United States would join the fledgling global program to eradicate smallpox, beginning with a program in West Africa. The American commitment to smallpox eradication represented a broader effort in the United States and the developing world to expand international health programs and build a Global Great Society. The Global Great Society came to grief, but global smallpox eradication would ultimately succeed. 相似文献

Current research does not support the notion that spelling is a simple rote-memory task. Learning to spell is better understood
as a complex developmental process that is interconnected with phonological awareness and reading ability. In this review,
three perspectives on spelling theory, research, and instruction are examined. Traditional classroom-based, developmental,
and structured language approaches are outlined and their implications for assisting poor spellers explored. Instructional
recommendations are made by drawing from and combining some of the strengths of each method. 相似文献
