There is always a general interest in the evaluation of the effects of training on the overall goals of an organization. This paper describes an approach being taken in the nuclear power industry concerning the effectiveness of training on safety. Several approaches to the development of performance indicators as means for monitoring this effectiveness are described. We conclude that the structured use of the opinions of subject–matter experts is virtually the only way to permit success. 相似文献

Intensity of exercise recovery, blood lactate disappearance, and subsequent swimming performance 总被引:1,自引:0,他引:1

The aim of this study was to examine the effects of active versus passive recovery on blood lactate disappearance and subsequent maximal performance in competitive swimmers. Fourteen male swimmers from the University of Virginia swim team (mean age 20.3 years, s= 4.1; stature 1.85 m, s= 2.2; body mass 81.1 kg, s= 5.6) completed a lactate profiling session during which the speed at the lactate threshold (V(LT)), the speed at 50% of the lactate threshold (V(LT.5)), and the speed at 150% of the lactate threshold (V(LT1.5)) were determined. Participants also completed four randomly assigned experimental sessions that consisted of a 200-yard maximal-effort swim followed by 10 min of recovery (passive, V(LT.5), V(LT), V(LT1.5)) and a subsequent 200-yard maximal effort swim. All active recovery sessions resulted in greater lactate disappearance than passive recovery (P < 0.0001 for all comparisons), with the greatest lactate disappearance associated with recovery at V(LT) (P= 0.006 and 0.007 vs. V(LT.5) and V(LT1.5) respectively) [blood lactate disappearance was 2.1 mmol l(-1) (s= 2.0), 6.0 mmol l(-1) (s=2.6), 8.5 mmol l(-1) (s= 1.8), and 6.1 mmol l(-1) (s= 2.5) for passive, V(LT.5), V(LT), and V(LT1.5) respectively]. Active recovery at VLT and V(LT1.5) resulted in faster performance on time trial 2 than passive recovery (P=0.005 and 0.03 respectively); however, only active recovery at V(LT) resulted in improved performance on time trial 2 (TT2) relative to time trial 1 (TT1) [TT2- TT1: passive +1.32 s (s= 0.64), V(LT.5) +1.01 s (s= 0.53), V(LT) -1.67 s (s= 0.26), V(LT1.5) -0.07 s (s = 0.51); P < 0.0001 for V(LT)). In conclusion, active recovery at the speed associated with the lactate threshold resulted in the greatest lactate disappearance and in improved subsequent performance in all 14 swimmers. Our results suggest that coaches should consider incorporating recovery at the speed at the lactate threshold during competition and perhaps during hard training sessions. 相似文献

Forty-nine learning disabled (LD), 30 emotionally disturbed(ED), and 44 unclassified (UC) boys originally sampled by Brooks (Note 1) and Jackson (Note 4) when they were 6 to 11 years of age, were relocated in 1979, and their current classification determined. Lambda, an index of predictive association, showed that a 53% improvement in the accuracy of prediction of 1979 classification was obtained when 1975 classification was given. The ED classification was the least stable, with 60% of the children originally classified ED changing their classification over four years, though only 19% of the originally LD and ED children were unclassified four years later. 相似文献

Setting cutoff scores is one of the most common practices when using scales to aid in classification purposes. This process is usually done univariately where each optimal cutoff value is decided sequentially, subscale by subscale. While it is widely known that this process necessarily reduces the probability of “passing” such a test, what is not properly recognized is that such a test loses power to meaningfully discriminate between target groups with each new subscale that is introduced. We quantify and describe this property via an analytical exposition highlighting the counterintuitive geometry implied by marginal threshold-setting in multiple dimensions. Recommendations are presented that encourage applied researchers to think jointly, rather than marginally, when setting cutoff scores to ensure an informative test. 相似文献

This paper presents an approach to investigating affect in the process of consultee-centered consultation. The anxiety and hostility of three consultants and consultees was assessed from an intensive analysis of their verbal behavior during consultation. Comparisons to normative data suggested that the anxiety and hostility expressed by consultees was high, relative to that expressed under more neutral conditions, and a relationship was observed between consultee anxiety and consultation outcome. It was concluded that this provides a potentially productive direction for future research in consultation. 相似文献

A set of behavioral objectives was developed for the consultant role of the school psychologist, based on Meyers' consultation model. A Likert-type questionnaire was developed to assess the degree to which teachers and school psychologists agreed upon the desirability and the actual accomplishment of these objectives. Based on a sample of 120 teachers and 83 school psychologists, it was found that both groups perceived a difference between the “desired” role and the role that school psychologists actually fulfill. However, there were also significant differences between teachers' and school psychologists' rating of the “actual” role, the school psychologists' rating agreeing more with the consultation model. Examination of individual items showed greater acceptance of objectives relating to Meyers' level of indirect service to the child, and less acceptance of Meyers' levels of direct service to the teacher and service to the school system. 相似文献
