博弈论视角下的可持续发展问题研究

可持续发展是属于外部不经济的公共地问题。从历史上看,造成目前一系列全球环境问题的主要责任在发达国家,所以,在可持续发展问题上,国际社会形成了共同但有区别的责任分摊原则。通过博弈模型分析发现,目前发达国家与发展中国家之所以谈判一再陷入僵局,是因为双方合作还缺乏适当的条件和机制,可持续发展问题的妥善解决,至少需要三个先决条件,但目前还没有一个条件已经满足。     

The effect of sensory awareness training on interpersonal social distance in fourth graders

The use of sensory awareness training and the place of training (youth hostel or regular classroom) were systematically controlled in 4 fourth-grade classrooms. The Horace Mann-Lincoln Social Distance Scale was given. A 2-way nested analysis of variance produced significant effects of intervention training in both settings. This supports the hypothesis that sensory awareness and personal contact promote lessening of social distance within groups. The training methods described in this study can easily be adapted for use in elementary classrooms as a part of group activities and as a counseling technique.
