This paper presents a detailed analysis of a newly developed system for the identification of nanomaterials and nanostructures of an arbitrary nature. The system has been created as a result of the joint work of the Committee on Data for Science and Technology (CODATA) and the International Council for Science (ICSI). It is shown that at its core the developed system is an extended set of metadata that reflect the conceptual framework of a scientific discipline. Their features include a wide coverage of the sum of the properties and characteristics, as well as the possibility of adding new headings, i.e., support for the evolution of the conceptual scheme that meets the requirements of the subject field. Limitations in the possibilities of the representation of certain categories of nanomaterials, especially of macroscopic objects, are found. It is shown that it is possible to overcome them by the active use of existing ontologies in the field of materials science.  相似文献

The article argues that the Federal government needs to develop special government-wide policies, similar to OMB Circular No. A-130, which would be applicable to scientific and technical information (STI). After exploring the relation between government information and government STI, the author points out that Federal statistics has its own special set of policies known as Statistical Policy Directives. STI's situation is different from other government information because it is carried out in the culture of science and academia, in the culture of classified information and export controls, and in the international arena. A policy circular for STI would touch on Federal research and development, technology transfer, classified and export control information, international considerations, interagency sharing, and several existing areas of policy. The Office of Management and Budget, the Office of Science and Technology Policy, or the National Science and Technology Council could issue the policy.  相似文献

This paper reviews a selection of international collaborative efforts in the production of information services and attempts to characterize modes of cooperation. Information systems specifically discussed include: international nuclear information system (INIS); Nuclear Science Abstract (NSA); EURATOM; AGRIS; AGRINDEX; Information Retrieval Limited (IRL); IFIS (International Food Information Service); Chemical Abstracts Service (CAS); MEDLARS; and TITUS. 3 methods of international information transfer are discussed: commercial transactions; negotiated (bilateral) barter arrangements; and contribution to internationally managed systems. Technical, economic, and professional objectives support the rationale for international cooperation. It is argued that economic and political considerations, as much as improved technology or information transfer, will determine the nature of collaboration in the future.  相似文献

Reproduction rights organizations, which administer reproduction copyrights collectively, are one of the major implementation mechanisms for copyright law, on both a national and an international level. The operation of RROs is described, with examples from Norway, Germany, the United Kingdom, and the United States. The International Federation of Reproduction Rights is discussed, and future plans for licensing databases are summarized. This article was adapted from a presentation to Latin American Copyright Specialists at the Library of Congress, Washington, D.C., May 1991, which was sponsored by the International Copyright Institute of the U.S. Copyright Office and the World Intellectual Property Organization.  相似文献

The purpose of this paper is to facilitate international research of medical resources on the World Wide Web. International research consists of overcoming a unique set of obstacles and challenges that are not involved when undertaking research tasks using only U.S.-based information. Utilizing the World Wide Web can help us to overcome most of the restraints we would have to face when we perform research outside of our local geography. Currently, there are a number of Internet Web sites that may assist us in breaking down the barriers to undertaking international research.  相似文献

The international mobility of scientists fosters knowledge exchange by increasing cross-country research collaboration between destination and origin countries. To the best of our knowledge, the mobility of international students, most of whom are not scientists, has not been linked to knowledge production involving both destination and origin countries in previous studies. The question of this research is whether international student mobility (ISM) contributes to science in China. To address this research question, we determined the annual number of international students studying in Chinese universities from 1999 to 2018, from the Concise Statistics of International Students in China compiled by the International Exchange Department of the Ministry of Education of the People's Republic of China, and corresponding publication records including the source country names in the titles, from the Web of Science database of Clarivate Analytics. We then used the fixed-effects negative binomial model and instrumental variable approach to explore the linkage from ISM to knowledge production and found that ISM led to the destination countries’ scientific research on foreign countries. The findings shed light on the discussion of the global mobility of talent, and contribute to the understanding of ISM's influence on science, the measurement of which is promising in future studies.  相似文献

以SCI和SSCI收录的7种情报学期刊在2000-2010年间的数据为样本,以作者文献耦合分析方法为研究视角,探寻新世纪以来情报学的知识结构。研究探测到:①情报学领域的几位具有较强研究活力以及广泛影响力的学者,作者的发文数、耦合频次以及作者在耦合网络中的中心性都是有关系的,但这种相关关系表现得并不强。②情报学的7个主要研究主题——科学计量学、网络资源管理与配置、信息检索、信息系统、知识管理、用户交互与服务、科学评价中,其科学计量学和网络资源管理与配置是两个主流研究主题;各研究主题之间的融合还有待于进一步加强。③与作者文献共被引分析法不同,作者文献耦合分析法以当前活跃的作者为分析对象,它可以从另一个角度来探析情报学的知识结构状况。  相似文献

If we wish to extend co-operation among the different peoples of the world on the basis of information exchanges, we must do more than create the global information infrastructure and highway which form the technological basis for the information society of the 21st century An effort must also be made to resolve sensitive issues involved in mutual understanding between peoples belonging to different cultures and speaking different languages. This will not come about if the tendency for some languages and cultures to dominate others is allowed to persist. A long-term international programme of action is needed to preserve cultural diversity and multilingualism in the infosphere. The basic forms of such action could include: preservation — by means of the appropriate media — of the cultural heritage of peoples with no written language; the development of computer translation systems; extension of the study of the most widely spoken languages (in terms of the number of speakers) in secondary and higher education; the elaboration and adoption of general ethical standards for the writing, reviewing and citing of scientific publications, particularly articles in periodicals; the elaboration of agreed scientific terminology in different languages; the development of co-operation on the inclusion of national literature in international databases; the devising of ways and means of protecting the infosphere from pollution. Given the world-wide importance of such action, it would be appropriate to conduct it under the auspices of UNESCO and of the International Council of Scientific Unions, as was done in the late 1960s and early 1970s for the UNISIST programme.  相似文献

This paper presents the bibliometric characteristics of 32 biomedical open access journals published by Academic Journals and International Research Journals – the two Nigerian publishers in Jeffery Beall's list of 23 predatory open access publishers in 2012. Data about the journals and the authors of their articles were collected from the websites of the publishers, Google Scholar and Web of Science. As at December 2012, the journals had together produced a total of 5,601 papers written by 5,599 authors, and received 12,596 citations. Authors from Asia accounted for 56.79% of the publications; those from Africa wrote 28.35% while Europe contributed 7.78%. Authors from Africa accounted for 18.25% of the citations these journals received, and this is about one‐third the number of citations by authors in Asia (54.62%). At country level, India ranks first in the top 10 citer countries, while Nigeria, the host country of the journals, ranked eighth. More in‐depth studies are required to develop further information about the journals such as how much scientific information the journals contain, as well as the science literacy of the authors and the editorial.  相似文献

This paper examines the way in which Taiwan is connected to on the World Wide Web in South Korea. The Web may represent a new channel for the communication among a global society's members and a reflection of international relations. Thus, it is necessary to explore the distribution of relations formed and maintained on the Web and the contents of those relations as well. This paper traced South Korean Web pages hyperlinking pages hosted in Taiwan, using a search engine. The context in which Taiwan appears in South Korean pages was also examined. Specifically, the structure of hyperlink connectivity from South Korea and Taiwan was analyzed. It was found that the hyperlink network was very sparsely connected in terms of the number of South Korean Web pages hyperlinking to the pages of the other country. The contents of hyperlink-connected information were categorized and analyzed. The most often occurring content category was ‘Computers & Internet’ in Taiwan. This suggests that South Korean Web users including organizations are more interested in computer-related products in Taiwan than any other things. The implication of this paper is to examine the state and form of international information flow from South Korea to Taiwan based on the patterns of hyperlink relations inscribed on South Korean Web pages and the type and content of information.  相似文献
