在小学双语活动课程中开展跨文化教育的思考

“双语教育”是在应21世纪新型人才的需要而诞生的。它的目的,不仅仅是为了改变学生学习外语的方式,更重要的是培养既精通汉语和汉语文化,又通晓英语及相关文化的双语人才,使学生获得更广泛的文化教育,包括对两种文化的协调互补和文化价值的多元理解。由于中西文化的差异,给双语教育带来了很多难题。而在双语活动课程中开展中西文化间的跨文化教育,从小培养学生树立相对的文化价值观、跨文化交际的意识与能力以及正确看待两种文化的态度,是解决双语跨文化教育难题的有效途径。一、树立相对的文化价值观文化交流产生于理解。在双语活动课程中…     

Understanding the track and field sprint start through a functional analysis of the external force features which contribute to higher levels of block phase performance

This study aimed to identify the continuous ground reaction force (GRF) features which contribute to higher levels of block phase performance. Twenty-three sprint-trained athletes completed starts from their preferred settings during which GRFs were recorded separately under each block. Continuous features of the magnitude and direction of the resultant GRF signals which explained 90% of the variation between the sprinters were identified. Each sprinter’s coefficient score for these continuous features was then input to a linear regression model to predict block phase performance (normalised external power). Four significant (p < 0.05) predictor features associated with GRF magnitude were identified; there were none associated with GRF direction. A feature associated with greater rear block GRF magnitudes from the onset of the push was the most important predictor (β = 1.185), followed by greater front block GRF magnitudes for the final three-quarters of the push (β = 0.791). Features which included a later rear block exit (β = 0.254) and greater front leg GRF magnitudes during the mid-push phase (β = 0.224) were also significant predictors. Sprint practitioners are encouraged, where possible, to consider the continuous magnitude of the GRFs produced throughout the block phase in addition to selected discrete values.     

The role of the teacher with substance-abusing adolescents in secondary schools

Before choosing to become involved with students who currently are abusing psychoactive substances, teachers must consider not only the potential consequences and payoffs to them professionally, but also what specifically they can do to help adolescents. This article presents some of the philosophical problems, and suggests potential solutions of how to relate to students who engage in potentially self-destructive, drug-related behavior. There is a need for teachers to become quasi-counselors and consultants, since they are the first line of defense against substance use and abuse.

《联合国海洋法公约》第76条与大陆架界限委员会《科学和技术准则》探析

1982年《联合国海洋法公约》创设了以其第76条和附件二为核心的200海里以外大陆架法律制度,使沿海国得以在大陆架界限委员会的指导和协助下依据国际法建立范围最大、也是最后的国家管辖海域。大陆架界限委员会制定了旨在协助执行《公约》第76条的《科学和技术准则》。《准则》将《公约》中相关规定加以详细说明,等于是《公约》第76条的执行细则。
