影响高校毕业生就业的社会资本因素分析   总被引:3,自引:0,他引:3  
社会资本是近年来学术界研究较多的一个问题。本文在对社会资本及大学生就业相关文献进行梳理的基础上,利用北京大学教育学院"高等教育规模扩展与劳动力市场"课题组于2005年6月对全国34所高校调查的数据,对大学生社会资本状况,社会资本对大学生毕业去向、就业落实率、起薪及工作满意度的影响,进行了实证分析。本文的主要研究结果如下:(1)与来自社会经济地位较高的家庭的学生相比,来自社会弱势家庭的学生在家庭社会资本与个人社会资本上都比较缺乏;(2)大学生毕业选择就业或升学时,家庭社会交往广泛度对升学选择产生显著的正面影响,而个人社会交往广泛度对就业产生了显著的正面影响;(3)社会资本与大学毕业生的就业落实、起薪、工作满意度存在着显著的正面影响;(4)社会资本对大专生和本科生就业落实率有较为显著的正的影响,但是对硕士和博士的就业落实率没有显著影响。  相似文献

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

Students in a large undergraduate biology course were expected to write a scientific report as a key part of their course design. This study investigates the quality of learning arising from the writing experience and how it relates to the quality of students’ preconceptions of learning through writing and their perceptions of their writing program that led to their report. Closed‐ended questionnaires investigating student conceptions and perceptions of writing, and approaches to writing, were completed by 121 students. Significant associations were found amongst qualitatively different prior and post conceptions of writing, approaches to writing and achievement. The results of the analyses suggest that the effective support of student experiences of writing reports requires teachers to be aware of the type of conceptions that students bring to their course and the perceptions they hold about the purpose of the writing program in which they are engaged.  相似文献

陈洪绶作为一个极其重要的人物画家,画法承接唐宋传统,融合元明文人笔墨程式,以怪诞奇崛的美学趣味独树一帜,清初曾一度被正统派文人画家、理论家视为野恶。然清末以来,推崇其绘画技法、绘学思想并在创作中借鉴、吸收了陈洪绶绘画中的许多有益营养而最终走向成功。在当今纷繁复杂的多元化社会里,也对21世纪传统人物画的探索发展起到一定的启示作用,并引发人们寻求传统人物画在现代文化情境下的拓展之路。近年另有学者将陈洪绶绘画与荷兰伦伯朗、西班牙委拉斯贵支油画人物做比较研究,然而将陈洪绶绘画与西方写实油画相比,难免也会出现偏颇,这种比较不免有些牵强。  相似文献

When hitting underground structures directly or exploding in rock-soil media near underground structures, the conventional weapons with large charge weight will make underground structures be subjected to strong shock vibration and cause personal casualty and damage of precision electronic equipments. The shock vibration has become one of the cardinal killing means of weapons. However, the existing methods of predicting structure shock vibration are limited evidently. In this paper the coupling coefficient of acceleration in clayey soil is obtained firstly. Subsequently based on repeated experiments of chemical explosion, after dimension analysis and by using method of multivariate stepwise regression, the calculation formulae of shock vibration acceleration for the underground structure are obtained finally. The formulae consider top and side explosion respectively, taking into account the effects of penetration depth, charge weight, distance to explosion center, rock-soil media, size of structure and buried depth. They are easy to use with high practicability and degree of confidence, and can provide credible evidence for prediction of shock vibration and vibration isolating design of underground structure.  相似文献
