Most large organizations, including universities, are fraught with institutional barriers to change. Their very structures can be impediments to the horizontal communication and cooperation necessary to effect broad-based innovation. U.S. automobile makers, however, are learning to overcome such structural obstacles to facilitate innovation. Can universities employ similar techniques? The recent experience of one regional university suggests important attributes of a successful model to facilitate curricular change.  相似文献

The use of simulation as an instructional tool can promote a deep conceptual understanding of statistics and lead to misunderstandings. Teachers need to be aware of the misconceptions that can arise as a result of simulation and carefully structure classroom activities so as to derive the benefits of this powerful instructional tool.  相似文献

Minimising joint torque is often used as an optimisation criterion when investigating human movement. Alternatively, an aspect of performance may be chosen to be maximised when investigating sporting movements. The aim of the study was to optimise the technique in the backward giant circle prior to a double layout somersault dismount from the high bar using various criteria to determine which best characterised the technique adopted by a gymnast. Ten recorded gymnast trials were used to determine bar release parameters and the level of noise in the gymnast’s movements. A computer simulation model of a gymnast and bar was used to optimise giant circle technique under three criteria: minimising joint torques, maximising the release window and maximising success in the presence of motor system noise. Local and global optimisations of technique were performed using the three criteria starting from the average technique of the 10 recorded trials. All global optimum solutions diverged from the gymnast’s technique. The local optimum for maximising success in the presence of noise had a success rate comparable with the global optimum (98% vs. 100%, respectively). It is concluded that the gymnast’s technique is characterised by maximising success despite operating with motor system noise.  相似文献

The recommendations of the Dearing Report concerning research organisation and content are critically examined. Many of them are seen to be benign and to adopt an appropriately pluralist approach to the objectives and working of the higher education system. The report is criticised, however, on several grounds. The Committee had a fragile grasp of the nature of knowledge and of its modes of production, and failed to remedy this by consulting sufficiently available international and national research. It is, therefore, inadequate as an example of the way in which research on higher education should be used in determining higher education policy. It takes for granted conventional wisdom on several key issues: the application of selectivity in research funding; the priority to be given to areas identified in the still largely unevaluated Technology Foresight programmes, and the relationships between uni- and multi-disciplinary work.  相似文献
