The distributional effects of higher education subsidies     

Mark Blaug 《Economics of Education Review》1982,2(3):209-231

This article provides a review of the inconclusive debate between Hansen-Weisbrod and Pechman on the distributional effects of subsidies to public higher education in California, with particular reference to its significance for other American states and for European countries. The cross-sectional effects are distinguished from the longitudinal, lifetime effects, and an effort is made to state the necessary and sufficient conditions to infer lifetime redistributive effects from observations of current data. Some general conclusions are drawn for the case of the United Kingdom.  相似文献   

Effective conditioning of female soccer players     

Polman R  Walsh D  Bloomfield J  Nesti M 《Journal of sports sciences》2004,22(2):191-203

We compared the efficacy of three physical conditioning programmes provided over a 12 week period (24 h in total) on selected anthropometric and physical fitness parameters in female soccer players. Two of the groups received physical conditioning training in accordance with speed, agility and quickness (SAQ); one group used specialized resistance and speed development SAQ equipment (equipment group; n = 12), while the other group used traditional soccer coaching equipment (non-equipment group; n = 12). A third group received their regular fitness sessions (active control group; n = 12). All three interventions decreased (P < 0.001) the participants' body mass index (-3.7%) and fat percentage (-1.7%), and increased their flexibility (+14.7%) and maximal aerobic capacity (VO2max) (+18.4%). The participants in the equipment and non-equipment conditioning groups showed significantly (P < 0.005) greater benefits from their training programme than those in the active control group by performing significantly better on the sprint to fatigue (-11.6% for both the equipment and non-equipment groups versus -6.2% for the active control group), 25 m sprint (-4.4% vs -0.7%), left (-4.5% vs -1.0%) and right (-4.0% vs -1.4%) side agility, and vertical (+18.5% vs +4.8%) and horizontal (+7.7% vs +1.6%) power tests. Some of these differences in improvements in physical fitness between the equipment and non-equipment conditioning groups on the one hand and the active control group on the other hand were probably due to the specificity of the training programmes. It was concluded that SAQ training principles appear to be effective in the physical conditioning of female soccer players. Moreover, these principles can be implemented during whole team training sessions without the need for specialized SAQ equipment. Finally, more research is required to establish the relationship between physical fitness and soccer performance as well as the principles underlying the improvements seen through the implementation of SAQ training programmes.  相似文献   

Age-related differences in vision and proprioception in a lower limb interceptive task: the effects of skill level and practice     

Williams AM  Weigelt C  Harris M  Scott MA 《Research quarterly for exercise and sport》2002,73(4):386-395

This study examined age-related differences in the role of visual proprioception during a lower limb interceptive action and how this varies as a function of skill and practice. In Experiment 1, skilled and less-skilled 8-, 10-, and 12-year-old boys controlled a soccer ball using their preferred foot under full vision and when sight of the effector was occluded. With the exception of the high-skilled 12-year-olds and low-skilled 8-year-olds, participants showed a decrement in peformance when denied access to visual proprioception. In Experiment 2, the effect of practicing under different informational constraints was examined for 12 year-old boys. Children performed varying amounts of practice under full vision, or in a condition where sight of the foot was occluded, before being transferred to the alternative viewing condition. Participants who practiced under occluded viewing conditions showed greater relative improvement in performance over practice and transfer sessions compared with a full vision control group. Some support is provided for the manipulation of visual informational constraints as an effective pedagogical approach to motor learning.  相似文献

Neither Public Nor Private: The Hybridization of Museums     

J. Mark Schuster 《Journal of Cultural Economics》1998,22(2-3):127-150

This paper takes a preliminary look at the hybridization of museums – the creation of a variety of mixed forms of governance incorporating both public and private governing authorities. Using data from three national surveys of American museums, the analysis documents the mix of types of governing authority and demonstrates how this mix varies across location, over time, and by museum type. The paper then estimates the extent of hybridization using several different indicators and speculates about its implications. The United States offers a particularly informative case because the general view is that American museums are (1) either public or private and (2) predominately private. While the second part of this view may still be a useful characterization of American museums, the first is no longer a particularly helpful way of understanding American museums, or, by extension, other cultural institutions, American or not. It is increasingly necessary to view cultural institutions through the lens of hybridization rather than privatization in order to improve our ability to document and predict their institutional behavior.  相似文献

This article is an edited and condensed version of the report of a study carried out under the auspices of the Joint Information Systems Committee (JISC) and the Publishers Association (PA). It develops the conclusions of an earlier analysis (Bide, Oppenheim & Ramsden, 1997) and builds upon discussions between representatives of JISC and the PA held in the summer of 1997.

Differential effects of norm-referenced and self-referenced feedback on performance expectancies,attributions, and motivation     

Wendy McColskey  Mark R. Leary 《Contemporary educational psychology》1985,10(3):275-284

When feedback is provided to students in a norm-referenced manner that compares the individual's performance to that of others, people who perform poorly tend to attribute their failures to lack of ability, expect to perform poorly in the future, and demonstrate decreased motivation on subsequent tasks. The present study examined the hypothesis that the deleterious effects of failure might be attenuated when failure is expressed in self-referenced terms—relative to the individual's known level of ability as assessed by other measures. In this study, subjects received feedback indicating that they did well or poorly on an anagram test, and this feedback was described as either norm-referenced (comparing the individual's performance to that of others) or as self-referenced (comparing performance to other measures of the individual's ability). As predicted, compared to norm-referenced failure, self referenced feedback resulted in higher expectancies regarding future performance and increased attributions to effort. Contrary to expectations, attributions to ability were not affected. The implications of the results for the structure of academic feedback are discussed.  相似文献
