Steven J. Condly Richard E. Clark Harold D. Stolovitch 《Performance Improvement Quarterly》2003,16(3):46-63
A meta‐analytic review of all adequately designed field and laboratory research on the use of incentives to motivate performance is reported. Of approximately 600 studies, 45 qualified. The overall average effect of all incentive programs in all work settings and on all work tasks was a 22% gain in performance. Team‐directed incentives had a markedly superior effect on performance compared to individually‐directed incentives. This effect was not influenced by the location of the study (business, government, or school), the competitive structure of the incentive system (programs where only the highest performers get incentives versus programs where everyone who increased performance receives incentives), the type of study (whether the study was a laboratory experiment or a field study), or the performance outcome (quality, quantity, or both). In these studies, money was found to result in higher performance gains than non‐monetary, tangible incentives (gifts, travel). More research is needed on the relative cost‐benefit of cash and gift incentives, and the way different types of tangible incentives are selected. Long‐term programs led to greater performance gains than shorter‐term programs did, and somewhat greater performance gains were realized for manual than for cognitive work. Explanations based on cognitive psychological principles accompany each of the analyses. 相似文献

Conductive education (CE) is widely reported as having a range of benefits. In the last two decades, it has expanded internationally. Educational psychologists may well encounter parents requesting this specialist intervention which is not normally offered within Local Authority special needs provision, for children with cerebral palsy and other motor difficulties. This paper reviews the empirical research to investigate the specific claims that CE improves motor skills, thinking skills and independence and the counter claim that it may cause harm. Implications for practice are discussed. 相似文献

Abstract The incidence of orthopedic problems was examined in 5, 582 men and women who attended the Cooper Clinic in Dallas, Texas between 1974 and 1982. The effects of age, physical activity, physical fitness, and body mass index (EMI) on the occurrence of these problems were examined using a proportional hazards approach. The expected risk of orthopedic problems per person-year was 0.045 for men and 0.046 for women. For men, physical fitness, BMI, and physical activity were associated with orthopedic problems, while for women, physical activity was the main predictor. Age was not a factor for either gender. The effect of change in physical fitness, physical activity, and BMI was examined in a subset of 2, 325 persons with more than one visit to the clinic. For women, physical activity and a decrease in BMI were associated with orthopedic problems, while for men none of those factors were significant. Again, age was not a factor in either group. The absence of any age effect on the occurrence of problems suggests that with regard to orthopedic problems, moderate amounts of physical activity in generally healthy persons may be recommended without special consideration as to age. 相似文献

Abstract This study investigated the effects of three types of recovery procedure on (a) circulatory recovery from a standardized bicycle ergometer exercise, (b) performance in a second standardized bicycle ergometer exercise, and (c) circulatory recovery from the second exercise. The recovery procedures were complete rest, light activity, and cold showers. Each of 10 male subjects underwent each recovery procedure on separate days. Analysis of variance for a randomized complete blocks design was used in the analysis of the data. Results indicated that cold showers decreased recovery heart rate after the first standardized exercise from 115 to 96 beats/minute and after the second exercise from 164 to 152 beats/ minute when compared with the other two conditions. Speed of performance in the second exercise was improved from 40.4 and 40.3 sec. in the case of rest and light activity to 38.9 sec. for cold showers. These improvements were all statistically significant at the .05 level. Three physiological explanations, not necessarily independent, are advanced: (a) local vasoconstriction of the skin vessels and vasodilatation of the muscle vessels causing a greater proportion of total blood flow to the working muscles, (b) establishment of a greater thermal gradient between the core and shell of the body allowing heat movement to the surface of the body by conduction between tissues rather than by skin blood flow, and (c) a decrease in sweat rate, thereby suppressing release of bradykinin, a vasodilator substance. 相似文献

Quality assurance in Higher Education: Fit for the new millennium or simply year 2000 compliant? 总被引:1,自引:0,他引:1
The current focus on quality assuranceprocedures emphasises compliance andaccountability. Drawing upon experience, mainlyfrom the UK, the article argues that whilstthis approach is understandable given thecircumstances of the 1990s, it has led to aninstitutional culture that is in danger ofalienating academic staff to the detriment ofthe system as a whole. If quality assurancesystems are to recognise the increasinglydiverse nature of higher education institutionsin the new millennium, compliance will need tobe balanced by a greater emphasis onencouraging innovation and self-improvement onthe part of individual members of staff. Bothquality assurance agencies and institutionsthemselves will need to adapt their policies,procedures and culture if higher educationsystems are to respond positively to thechallenges of the new millennium. 相似文献
