目的：探讨大学生时间管理倾向及其与考试焦虑的关系。方法：选取文科二年级学生2个班级,理科二年级学生2个班级,共203人,随机分成实验组（接受时间管理训练）和对照组（不接受时间管理训练）,采用考试焦虑量表、心理症状自评量表（SCL-90）和时间管理倾向量表,对实验组和对照组进行前测和后测。结果：考试焦虑和时间管理倾向之间存在负相关。时间管理训练后,试验组的时间管理倾向水平提高,心理健康水平有所提升,考试焦虑水平下降。结论：时间管理训练可以提升学生时间管理倾向水平,提高心理健康水平,降低考试焦虑,建议高校将时间管理教育与心理健康教育相结合,提升大学生时间管理能力及心理健康水平,从而降低考试焦虑。 相似文献

目的:探讨人格特质对青少年锻炼行为的影响,考察运动友谊的中介效应。方法:采用大五人格量表、青少年运动友谊质量量表和体育活动等级量表对1466名青少年进行调查。结果:人格特质、运动友谊对青少年锻炼行为的影响显著,其中,外向性人格突出者或运动友谊质量水平高者的锻炼参与越频繁,神经质人格突出者锻炼的持续时间越短;回归分析证实了,运动友谊质在人格特质影响锻炼行为时具备部分中介效应。结论:青少年锻炼行为的差异或因个体不同的人格特质和不同的运动友谊所致;发展开放性、外向性、宜人性、严谨性等积极人格特质,缓解神经质倾向,同时搭建提升青少年运动友谊的平台,可能是促进青少年锻炼行为的一个有效策略。 相似文献

本文借鉴社会交换理论和不确定性理论,利用810份问卷数据进行回归分析,实证研究员工工作价值观、组织公平对离职倾向的主效应和调节效应及其代际差异。研究发现：（1）工作价值观是员工离职倾向强前置预测因素,且预测效应存在代际差异;（2）舒适与安全和能力与成长型工作价值观对离职倾向具有负向作用,且舒适与安全的负向效应更大,而地位与独立对离职倾向具有正向作用;（3）工作价值观对离职倾向的预测作用在“70后”中效应最强,在“90后”中最弱;（4）组织公平部分调节了工作价值观对离职倾向的预测效应,如组织公平放大了舒适与安全型价值观对离职倾向的负向预测效应,减弱了地位与独立型价值观对离职倾向的正向预测效应,且调节效应在代际之间存在显著的差异。 相似文献

Aresearch group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol--a chemical found in the skins of red grapes and in red wine--can improve the sensitivity of mice to the hormone insulin, according to a report in the October,2007 issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of Type 2 diabetes, the findings“provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said. 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

This essay focuses on universal service and the Internet as means to support social and political participation. The emphasis on access to telecommunications systems in conventional approaches to universal service is contrasted with access to content. A model of the information environment is described that accounts for the roles of content and conduit, both of which are necessary conditions to achieve true access. A method is outlined for employing information indicators to observe or measure the information environment. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献
