一、研究背景
中华文明是世界四大文明古国中唯一未曾中断、延续至今的文明。中华文明5000年的说法由来已久,由于其开始阶段远在甲骨文出现之前,尽管古史传说中记载了一些当时的故事,但是不能作为信史。那一大段没有文字的历史只有通过考古发掘,依据对出土的遗迹和遗物的研究结果来撰写。因此,国家科技支撑计划实施的“中华文明探源工程”被誉为是为中华民族修家谱的盛举。多年来, 相似文献

塞缪尔·亨廷顿认为导致未来国际冲突的根源是不同类型的文明,他认为未来的冲突最有可能发生在西方文明与伊斯兰文明、西方文明与中华文明之间.亨廷顿文明冲突论的实质是为美国和西方的国家利益服务.具有"和合"精神的中华文明不是引起未来国际冲突的因素,恰恰相反,中华文明是维护国际和平的重要力量. 相似文献

中华文明经过夏、商、周三代的发展,在百家争鸣的春秋战国时期奠定了科学的理性基础。在君主专制的体制和儒道互补的思想背景下发展的中国科学技术,在秦汉时期形成自己的诸学科范式,其后经历了南北朝、北宋和晚明三次高峰期,在从"农业文明"向"工业文明"转变的过程中开始落伍。北宋以来沿着自己传统的科学近代化趋势,由于"靖康之变"、"甲申鼎革"和"虎门销烟"相继三次挫折而泯灭,最终通过移植西学而融入世界科学体系。在人类文明的广泛交流和融合过程中,中国科学的传播以及它作为中华文明接受外来文明的基础之一而成为世界科学技术史的一部分。 相似文献

中国的文化源远流长,这其中各具特色的少数民族文化为中华文明添上了浓墨重彩的一笔。无论是从文明的角度,还是从民族的角度,少数民族文化都应该一代一代传承下去,留给子孙后代无价的精神财富。随着科技的进步、媒体的发展,少数民族地区的广播电视逐渐繁荣发展。多年来,少数民族地区媒体一方面时刻牢记自身的宣传使命,把党和政府的声音传入千家万户,另一反面,积极制作具有民族特色的节目,为传承和发扬民族文化做出了巨大贡献。本文以延边朝鲜语广播电视为例,分析广播电视对少数民族文化的传承与发展所做的贡献。 相似文献

A research 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 in red wine-can improve the sensitivity of mice to the hormone insulin according to a report in the October issue of Cell Metabolism.…… 《中国科学院院刊(英文版)》2008,22(1):14-15
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

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

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

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
