相信最近的一些新闻报道对于海德堡而言并非什么好消息.舆论大肆宣扬受经济危机影响而惨遭重创的印刷市场,报道众多印刷设备供应商因为订单急减而在收益上大幅缩水。近日在德国财经的报纸上甚至有传言宣称海德堡和曼罗兰正在着手讨论合并的可能性.而两家公司都不愿就此发表任何评论。然而上周还有一件非常有趣的新闻是海德堡的创新项目Linoprint。  相似文献

Andrew Turner, who teaches in a school for pupils with severe learning difficulties, considers the teaching of history by teachers of such pupils and suggests that the skills of imaginative reconstruction and empathy are relatively neglected areas, particularly when dealing with distant historical periods. Recent research with mainstream primary pupils illustrates the possible parallels and the article gives details of a small-scale study of one group of Key Stage 3 pupils.  相似文献

T'ai Chi Chuan (TCC) is a widely practiced Chinese martial art said to physically develop balance and coordination as well as enhance emotional and mental health. TCC consists of a series of postures combined into a sequential movement providing a smooth, continuous, low-intensity activity. The purpose of this study was to examine the ventilatory and cardiovascular responses to the Long Form of Yang's style TCC. In addition, the subjects' TCC responses were compared to their ventilatory and cardiovascular responses during cycle ergometry at an oxygen consumption (VO2) equivalent to the mean TCC VO2. Six experienced (M = 8.3 yrs) male TCC practitioners served as subjects with data collected during the Cloud H and movement of the TCC exercise. Significantly (p less than .05) lower responses for ventilatory frequency (Vf) (11.3 and 15.7 breaths.min-1), ventilatory equivalent (VE/VO2) (23.47 and 27.41), and the ratio of dead space ventilation to tidal volume (VD/VT) (20 and 27%) were found in TCC in comparison to cycle ergometry. The percentage of minute ventilation used for alveolar ventilation was significantly higher during TCC (p less than .03) than cycle ergometry, with mean values of 81.1% and 73.1%, respectively. Cardiac output, stroke volume, and heart rate were not significantly different between TCC exercise and cycle ergometry at the same oxygen consumption. We concluded that, during TCC, expert practitioners show significantly different ventilatory responses leading to more efficient use of the ventilatory volume than would be expected from comparable levels of exertion on a cycle ergometer.  相似文献

This paper discusses the current fashion for brain‐based learning, in which value‐laden claims about learning are grounded in neurophysiology. It argues that brain science cannot have the ‘authority’ about learning that some seek to give it. It goes on to discuss whether the claim that brain science is relevant to learning involves a category mistake. The heart of the paper tries to show how the contribution of brain science to our grasp of the nature of learning is limited in principle. Finally the paper explores the potential of brain science to illuminate specific learning disabilities.  相似文献
