优化问题的新步长法则

The step-size procedure is very important for solving optimization problems. The Armijo step-size rule, the Armijo-Goldstein step-size rule and the Wolfe-Powell step-size rule are three well-known line search methods. On the basis of the above three types of line search methods and the idea of the proximal point methods, a new class of step-size rules was proposed. Instead of a single objective function f, f ＋1/2（x - xk）^TBk（x-Xk） was used as the merit function in iteration k, where Sk is a given symmetric positive definite matrix. The existence of the steplength for the new rules was proved. Some convergence properties were also discussed.     

Global Social Responsibility: Developing a Scale for Senior High School Students in Japan

This research was conducted with the aim of clarifying a concept of “global social responsibility.” A total sample of 395 senior high school students in Japan responded to a pool of items mostly adapted from a scale developed by Starrett (1996) and provided additional data concerning their social experiences. The data were used in the development of a Japanese version of the Global Social Responsibility (GSR) scale. It was found that “global altruism,” “active involvement with society,” and “understanding of interdependence” constituted a construct of global social responsibility. It was also found that females, those who discussed social problems with their family, those who revealed a high awareness of responsibility and those who had multiple experiences of volunteer activities for community service showed high GSR scores. The scale provides both an awareness of the concept and a measure for determining levels of global social responsibility. Counseling professionals are encouraged to consider their roles from a global and social perspective, with the notion of responsibility being seen as central to the concepts of freedom and personal development.     

Improving quality of the child care environment through a consultancy programme for centre directors

This study examined the effects of a newly developed on-site consultancy programme to improve global quality of the child care environment in non-parental child care centres for 0- to 4-year-old children as measured with the ITERS-R/ECERS-R. Using a randomised controlled trial with a pretest, posttest, and follow-up test, we compared 35 experimental group with 33 control group. The consultancy programme comprised three consultations in total. Analysis on the items that were specifically targeted during the consultancy showed a significant improvement on these targeted items between pretest and posttest and between posttest and follow-up. The effect of the consultancy programme on the total scores (including the non-targeted items) was not significant.     

外语习得中母语文化的负迁移现象及对策

外语教学不仅是语言教学，也是化教学。不同化之间具有鲜明的民族性，呈现出不同的化形态，反映到作为化载体的语言上则表现为语言表达的差异。母语化的影响根深蒂固，对目的语的学习必然会产生一定的负迁移作用。由于母语化负迁移造成理解错误，或使交际陷入尴尬境地的例子不胜枚举。如何逐步了解目的语国家的化、增强化差异意识，克服母语化的负迁移现象，是外语学习中的一个重要课题。
