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.  相似文献

Student belonging and engagement has received increased attention in the context of an expanding and more diverse higher education student population. Student retention is regarded as a priority with many universities augmenting their retention strategies to instil a sense of belonging. This article provides insights into first year Business Management students’ experiences of starting their degrees and retention interventions at a university in the South of England. It is based on findings from an ongoing study that applied Wenger's social theory of learning and adopted an appreciative inquiry approach to focus group interviewing to investigate students’ perceptions. Students developed a sense of belonging, constructed learner identities, made sense of their learning and gained confidence, but also experienced instances of tension and frustration that raise questions about the extent to which sociality practices within evolving communities of practice can address diverse engagement and identity development needs and mitigate disengagement.  相似文献

在课堂教学中发现,学生难以理解在被冲击物的水平方向上施加冲击物的重力来计算动荷因数。本文研究了不同水平静荷载的施加对冲击问题的影响,推导出水平冲击问题求解的通用公式,证明水平冲击问题与静荷载的施加方式及大小无关。若采用动荷因数法,需选择冲击物自身重力作为被冲击物的水平静载,才可得到教材中的结果。结合国外材料力学教材,介绍了水平冲击问题的另一种求解方法,拓宽了读者求解水平冲击的思路,并给出相应的教学建议。  相似文献

投资需求和外贸需求仍然是拉动经济增长的主要力量,消费需求不足,平均消费率过低仍然是国内需求不足的主要原因。当前制约我国居民消费需求的主要因素有即期收入增长缓慢,收入差距过大,预期支出快速扩张,消费环境不尽完善等。因此,增加居民即期收入,缩小地区、部门、行业与个人收入差距,降低居民预期支出,提高居民消费信心,增加有效供给,改善居民消费环境等是扩大内需的有效途径。  相似文献

This article proposes procedures for assessing and controlling acquiescence in personality scales when acquiescence is related to the content that the scale intends to measure. Our proposal is comprehensive in that it can be applied to different item response formats fitted with response models that can be parameterized as factor-analytic models. In the calibration stage, our proposal makes joint use of a balanced scale and a set of markers for acquiescence, and consists of 2 sequential procedures: a direct semirestricted solution, and a restricted solution with minimal identification constraints. In the scoring stage, we discuss how the information given by the acquiescence–content relation can be used to obtain Bayes expected a posteriori scores. The robustness of the direct procedure is assessed both analytically and by simulation. A free, user-friendly program that implements the procedures proposed is made available. Practical issues of use and interpretation are discussed and illustrated with an empirical application.  相似文献
