海洋是国家战略必争领域，建设海洋强国必须要提高海洋资源开发能力，发展海洋经济，保护海洋生态环境，坚决维护国家海洋权益。推动海洋科技实现高水平科技自立自强，是加快建设海洋强国的必然要求。海洋观测探测技术是认识海洋的基本手段，是海洋资源开发、环境保护和权益维护的重要基础。文章回顾了全球和我国海洋观测探测计划和观测网络取得的重要进展，重点介绍了中国科学院海洋科学观测探测技术体系构建的实践，并对下一步发展提出了思考和展望。构建自立自强的海洋科学观测探测技术体系，要进一步加强顶层设计，推动国家战略需求和科技前沿问题“双引擎”；强化科技攻关，瞄准最紧急、最紧迫的关键问题持续发力；创新体制机制，充分发挥海洋领域国家战略科技力量作用，为我国海洋强国建设提供强有力的科技支撑。 相似文献

基于2004—2018年我国31个省份海洋相关数据,运用自回归分布滞后(ARDL)-误差修正(ECM)模型,分析海洋科技创新与海洋经济发展、海洋产业结构转型升级之间的长期均衡与短期动态关系,并结合格兰杰因果关系检验进行探讨.结果表明:海洋科技创新投入和产出的增加能够带来海洋生产总值的增加,海洋产业结构优化对海洋经济发展有正向推动作用,海洋经济发展也是海洋科技创新、海洋产业结构优化的格兰杰原因;而相比海洋科技创新投入,当前海洋科技创新产出对海洋产业结构转型升级以及海洋经济发展的作用相对较小.据此,提出贯彻海洋创新驱动发展战略、顶层设计结合市场资源配置、推进海洋科技创新对外开放进程、加快科技成果转化的同时兼顾海洋生态文明建设等政策建议. 相似文献

通过构建海洋科技创新评价体系,利用熵权-TOPSIS法测量中国36个涉海城市的海洋科技创新能力,并利用空间统计工具分析这些城市海洋科技创新能力的区域特征。研究结果表明:36个涉海城市的海洋科技创新能力呈现“金字塔”结构,能力较强的城市集中在环渤海、长三角、珠三角3个海洋经济区且为区域中心城市,其余多数城市的海洋科技创新水平相对较低;各城市海洋科技创新能力的空间特征表现为异质性强、外溢效应不明显。最后基于测度分析结果,提出应加强国家顶层设计和战略部署,实现不同涉海主体之间的优势互补、信息共享和协同创新,推进海洋产业集群与技术空间扩散,加快中国海洋领域的科技创新资源整合与技术进步。 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

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

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

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
