Health sciences librarians are being called upon to be more proactive in their institutions' continuing education efforts. In an effort to identify whether search requests indicated CE needs, a study was conducted by a group of members of GaIN (Georgia Interactive Network for Medical Information). MEDLINE requests from health care professionals for subject specific clinical topics were collected during a six-month period via a standard search request form created for the study. Copies of all completed requests were collected and broad ICD-9 codes assigned to the search topics. Institutional reports were generated for each participating library to share with hospital CE coordinators. They were also compiled for the group as a whole, and reflected the "hottest" topics requested during the study period for physicians and for non-physicians (nurses, allied health, administrators). A survey to hospital librarians and CE educators showed some value in the reports, but greater potential for further collaboration between librarians and CE coordinators.  相似文献

Differences in activation patterns between eccentric and concentric quadriceps contractions.     

Malachy P McHugh  Timothy F Tyler  Scott C Greenberg  Gilbert W Gleim 《Journal of sports sciences》2002,20(2):83-91

Previous studies analysing electromyograms (EMGs) from indwelling electrodes have indicated that fast-twitch motor units are selectively recruited for low-intensity eccentric contractions. The aim of this study was to compare the frequency content of surface EMGs from quadriceps muscles during eccentric and concentric contractions at various contraction intensities. Electromyograms were recorded from the rectus femoris, vastus lateralis and vastus medialis muscles of 10 men during isokinetic (1.05 rad x s(-1)) eccentric and concentric knee extension contractions at 25%, 50%, 75% and 100% of maximal voluntary contraction (MVC) for each contraction mode. Additionally, isometric contractions (70 degrees) were performed at each intensity. The mean frequency and root mean square (RMS) of the surface EMG were computed. Mean frequency was higher for eccentric than concentric contractions at 25% (P < 0.01), 50% (P < 0.01) and 75% (P < 0.05) but not at 100% MVC. It increased with increasing contraction intensity for isometric (P < 0.001) and concentric (P < 0.01) contractions but not for eccentric contractions (P = 0.27). The EMG amplitude (RMS) increased with increasing contraction intensity similarly in each contraction mode (P < 0.0001). Higher mean frequencies for eccentric than concentric contractions at submaximal contraction intensities is consistent with more fast-twitch motor units being active during eccentric contractions.  相似文献

Adjunct question effects with review     

Philippe C. Duchastel  Ronald J. Nungester 《Contemporary educational psychology》1984,9(2):97-103

The effects on retention of adjunct questions either placed at the end of a passage or inserted after their respective paragraphs within the passage were examined. The high school subjects were encouraged to review the materials after encountering the questions, a departure from traditional procedures in the field. Both treatments led to superior retention of the previously questioned facts when compared to a passage-only control group, but did not increase retention of previously unquestioned facts. The position of the adjunct questions did not differentially affect performance. The discrepancy of the results from those traditionally reported are interpreted in terms of the procedures employed.  相似文献   

Measuring Socioeconomic Status at the School Level     

James H. McMillan  Gary T. Henry  Diane Crosby  Kent C. Dickey 《Educational Measurement》1995,14(1):15-21

Why is there an increased need for quantitative indicators of student socioeconomic status at the school level? What alternative approaches have been used to measure SES? Can principals accurately estimate the SES distribution of their student populations? How do their estimates correlate with other indexes o f family SES?  相似文献

The marketing audit: a new perspective on library services and products     

P J Wakeley  C Poole  E C Foster 《Bulletin of the Medical Library Association》1988,76(4):323-327

A marketing audit enables a library to look at audiences, services, and products with a structured approach. The audit can be used to assess operations and to provide a framework for ongoing decision making, evaluation, and long-range planning. An approach to the audit process is presented and its application is demonstrated in a case study featuring the American Hospital Association Resource Center.  相似文献
