The paper reviews the way in which Steiner schools have attached importance to the categorisation of pupil character and behaviour, drawing on a tradition going back to ancient Greek science. 相似文献

This paper examines how teachers responded when some organizational constraints on their work were loosened and why they responded as they did. It first reviews the sociological literature on teacher work to identify the main determinants studied. It then presents results of an ethnographic study of teachers in an urban school. The literature tends to portray teacher work as overly determined and may remove more responsibility from teachers for determining their own work than is warranted. 相似文献

The intent of this project was to explore the feasibility of personalising the paddle blade size for individual flatwater
kayakers based on their power output profiles. Twelve elite male kayakers performed on a kayak ergometer at the same intensity
and resistance that they would normally experience while paddling at race pace for 500 m on the water. The kayak ergometer
was instrumented so that power profiles could be determined from the instantaneous force and velocity of the representative
centre point of the paddle blade. From the power profile information, the researchers calculated a personalised blade size
that was expected to improve performance for those kayakers differing more than 5% from the calculated ‘ideal’ size. For the
elite kayakers studied, it was recommended that seven of the paddlers should increase their blade size by approximately 5–10%.
For the remaining five paddlers, the results indicated that their current blade sizes were within the expected measurement
error of their predicted ideal value and should be retained. It is anticipated that this research will provide the theoretical
rationale for elite kayakers to see the need to personalise their blade size based on their own muscle power profiles. 相似文献

It has been shown (Lawrence, S. (2001). Online or invisible? Nature, 411, 521) that journal articles which have been posted without charge on the internet are more heavily cited than those which have not been. Using data from the NASA Astrophysics Data System (ads.harvard.edu) and from the ArXiv e-print archive at Cornell University (arXiv.org) we examine the causes of this effect. 相似文献
