Objective: To identify or develop a critical appraisal instrument (CAI) to aid in the selection of search filters for use in systematic review searching. The CAI is to be used by experienced searchers without specialized training in statistics or search filter design. Methods: Through extensive searching and consultation, one candidate instrument was identified. Through expert consultation and several rounds of testing, the instrument was extensively revised to become the Canadian Agency for Drugs and Technologies in Health (CADTH) CAI. Results: The CADTH CAI consists of ten questions and can be applied by experienced searchers with a moderate knowledge of search filter methodology. Conclusion: The CADTH CAI provides experienced searchers with a means of selecting the search filter that is most methodologically sound. 相似文献

Diurnal variation in cycling performance: influence of warm-up 总被引:2,自引:0,他引:2
We examined the effects of time of day on a cycling time trial with and without a prolonged warm-up, among cyclists who tended towards being high in "morningness". Eight male cyclists (mean +/- s: age = 24.9 +/- 3.5 years, peak power output = 319 +/- 34 W, chronotype = 39 +/- 6 units) completed a 16.1-km time trial without a substantial warm-up at both 07:30 and 17:30 h. The time trial was also completed at both times of day after a 25-min warm-up at 60% of peak power. Power output, heart rate, intra-aural temperature and category ratings of perceived exertion (CR-10) were measured throughout the time trial. Post-test blood lactate concentration was also recorded. Warm-up generally improved time trial performance at both times of day (95% CI for improvement = 0 to 30 s), but mean cycling time was still significantly slower at 07:30 h than at 17:30 h after the warm-up (95% CI for difference = 33 to 66 s). Intra-aural temperature increased as the time trial progressed (P < 0.0005) and was significantly higher throughout the time trials at 17:30 h (P = 0.001), irrespective of whether the cyclists performed a warm-up or not. Blood lactate concentration after the time trial was lowest at 07:30 h without a warm-up (P = 0.02). No effects of time of day or warm-up were found for CR-10 or heart rate responses during the time trial. These results suggest that 16.1-km cycling performance is worse in the morning than in the afternoon, even with athletes who tend towards 'morningness', and who perform a vigorous 25-min warm-up. Diurnal variation in cycling performance is, therefore, relatively robust to some external and behavioural factors. 相似文献

The impact of Sensory Processing Difficulties across a range of Special Educational Needs is well researched. More recently, the impact on children’s mental health and well-being, linked with anxiety, depression and self-injurious behaviours, have redirected international research to consider the holistic benefits of sensory provision, for those with special educational provision and the wider classroom population. A SMART SURVEY was designed to collate empirical evidence regarding current sensory awareness and provision in mainstream primary schools throughout Northern Ireland, in a time efficient manner. Out of 809 schools, 164 (20.27%) fully completed the online survey. Findings indicate that Special Educational Needs Coordinator confidence in developing practice, supporting staff and children was limited and impaired by insufficient and inconsistent training opportunities. While healthcare research recommends provision by trained professionals, Occupational Therapy input was limited (n = 34; 24.8%), resulting in practice that could be detrimental rather than beneficial to children’s progress. Respondents identified a need for sensory training for teachers (n = 124; 93.94%) to ensure that the impact of Sensory Processing Difficulties on the holistic development of all children is understood. Pupil voice was undervalued (n = 5; 3.6%). Active involvement of children in the process of evaluation and intervention is recommended to enhance pupil autonomy and well-being. 相似文献

In this study we use concept maps as the tool for examining concepts presented in three high school computer textbooks. All three textbooks were endorsed by Taiwan's Ministry of Education (MOE). The concepts relating to CPU was selected as a sample for analysis. Two high school computer teachers first worked independently and then together to draw concept maps for each of the textbooks. Our analysis revealed that the textbooks did not cover the important concepts appropriately and failed to address the connections between the concepts. While all three textbooks elaborated on some concepts using examples, only a few analogies were used. The study also showed that concept maps can be an effective tool for analyzing the conceptual framework of important concepts within a textbook. 相似文献
