外语教学中文化差异敏感性的培养

现代外语教学强调培养学生的跨文化交际能力,即在国际化、信息化社会中获得信息和处理信息的能力。现状调查和分析表明：目前外语学习者跨文化意识和文化差异敏感性并不强烈,文化教学在英语教学中的重要性也没有得到充分体现。因此,如何在外语教学中从不同的层面来培养学生的跨文化意识和文化差异的敏感性,提高其跨文化交际能力成为亟待解决的问题。

Do driver training programs reduce crashes and traffic violations? — A critical examination of the literature

This paper reviews the evaluation literature on the effectiveness of classroom and behind-the-wheel driver training. The primary focus is on North America programs as originally taught in high schools but now also by private instructors. Studies from the United Kingdom, Australia, New Zealand and Scandinavia are also included.By far the most rigorous study to date was the experimental study in DeKalb, Georgia, U.S.A. This study used a randomized design including a control group and a very large sample size to provide reasonable statistical precision. I reexamine the DeKalb data in detail and conclude that the study did show evidence of small short-term crash and violation reductions per licensed driver. However, when the accelerated licensure caused by the training is allowed to influence the crash and violation counts, there is evidence of a net increase in crashes.The other studies reviewed present a mixed picture but the better designed quasi-experimental evaluations usually showed no effects on crash rates but almost all suffer from inadequate sample size. I show that as many as 35,000 drivers would be required in a two group design to reliably detect a 10% reduction in crash rates.The advent of GDL laws in North America and other countries has largely remedied the concern over accelerated licensure of high risk teenage drivers by delaying the progress to full licensure. Conventional driver training programs in the U.S. (30 h classroom and 6 h on-the-road) probably reduce per licensed driver crash rates by as little as 5% over the first 6-12 months of driving. The possibility of an effect closer to 0 cannot be dismissed.Some GDLs contain an incentive for applicants to complete an advanced driver training program in return for shortening the provisional period of the GDL. The results of Canadian studies indicate that any effects of the driver training component are not sufficient to offset the increase in accidents due to increased exposure.There is no evidence or reason to believe that merely lengthening the number of hours on the road will increase effectiveness. Programs directed toward attitude change and risk taking better address the underlying cause of the elevated crash risk of young drivers but these behaviors are notoriously resistant to modification in young people.     

大吨位徐变仪球铰非线性接触分析

因研究桥用高强度混凝土材料徐变性能的需要,自主研制了大吨位徐变仪。对于处于接触受力状态的徐变仪球铰区域,先用Hertz接触理论估算球铰区域尺寸范围,然后利用ANSYS通用有限元软件对该区域分别取2种垫板凹槽球径的模型进行接触分析,通过对比球铰区域的最大接触压力、mises应力、第3主应力来进一步确定垫板凹槽的合理球径。用该徐变仪对2座大桥成功进行了高强度混凝土徐变试验,并实际验证了试验荷载下徐变仪球铰区域的受力性能,以及有限元接触分析结果的正确性。
