为了保存国家数字文化遗产,传承民族记忆,需将法定呈缴制度的客体延伸至数字出版物。通过调研国外典型立法,发现数字出版物概念的内涵发生了显著变化,公开提供获取利用的数字资料都可视为数字出版物,应将其纳入到法定呈缴的客体范围。国际立法经验显示,网络出版物客体的界定是需要解决的核心问题,可以从创建发布者、资源内容角度判断纳入一个国家法定呈缴体系的网络出版物客体。为了适应客体的变化,需要革新法定呈缴实施的方式。图1。表1。参考文献38。 相似文献

A standard procedure in citation analysis is that all papers published in one year are assessed at the same later point in time, implicitly treating all publications as if they were published at the exact same date. This leads to systematic bias in favor of early-months publications and against late-months publications. This contribution analyses the size of this distortion on a large body of publications from all disciplines over citation windows of up to 15 years. It is found that early-month publications enjoy a substantial citation advantage, which arises from citations received in the first three years after publication. While the advantage is stronger for author self-citations as opposed to citations from others, it cannot be eliminated by excluding self-citations. The bias decreases only slowly over longer citation windows due to the continuing influence of the earlier years’ citations. Because of the substantial extent and long persistence of the distortions, it would be useful to remove or control for this bias in research and evaluation studies which use citation data. It is demonstrated that this can be achieved by using the newly introduced concept of month-based citation windows. 相似文献

The kind and size of a library determines the need to collect and the method of controlling government publications. New Zealand libraries tend to handle these publications like any other book with the exception of official records and statistics. As a rule, public, rather than academic libraries, are the designated depositories. In comparing the concept of New Zealand libraries to that of the University of Oregon Library concerning government publications, I found that New Zealand libraries collect and store official and statistical publications and give them partial use; most government publications are integrated into the general collection (use is not known), and few libraries have separate government publication sections with special librarians governing the collection. On the other hand the University of Oregon collects all types of government publications for optimum use; many have been integrated into the general collection (use is not known); and a separate documents section is open to the public with several librarian specialists in attendance. Government publications in the general collection are not, as a rule, recognized as government publications by the public, but those publications are readily accessible. Many government publications at the University of Oregon Library are housed in the general collection, but since 1974 publications of the United States, Canada and many international organizations are shelved in the Documents Section. Use of the various classification schemes has proved successful; however, changes and improvements should be considered frequently to make the government publications collection the best able to serve the public. 相似文献

ABSTRACT As new digital technologies make the storage of redundant print copies less important, as strained budgets can support fewer subject specialists, and as demands for new services such as data stewardship rise, it is clearer now than ever that libraries’ traditional consortia and their places and roles within academic institutions must be rethought and changed expeditiously if academic libraries are to be vitally important. This article, a companion piece to Joan Giescke's article in this issue, explores this concept and offers some possible models for collaboration. 相似文献

This article presents a case study of the open data project in the Chicago area. The main purpose of the research is to explore empowering potential of an open data phenomenon at the local level as a platform useful for promotion of civic engagement projects and provide a framework for future research and hypothesis testing. Today the main challenge in realization of any e-government projects is a traditional top–down administrative mechanism of their realization itself practically without any input from members of the civil society. In this respect, the author of the article argues that the open data concept realized at the local level may provide a real platform for promotion of proactive civic engagement. By harnessing collective wisdom of the local communities, their knowledge and visions of the local challenges, governments could react and meet citizens' needs in a more productive and cost-efficient manner. Open data-driven projects that focused on visualization of environmental issues, mapping of utility management, evaluating of political lobbying, social benefits, closing digital divide, etc. are only some examples of such perspectives. These projects are perhaps harbingers of a new political reality where interactions among citizens at the local level will play a more important role than communication between civil society and government due to the empowering potential of the open data concept. 相似文献

Twitter accounts have already been used in many scientometric studies, but the meaningfulness of the data for societal impact measurements in research evaluation has been questioned. Earlier research focused on social media counts and neglected the interactive nature of the data. We explore a new network approach based on Twitter data in which we compare author keywords to hashtags as indicators of topics. We analyze the topics of tweeted publications and compare them with the topics of all publications (tweeted and not tweeted). Our exploratory study is based on a comprehensive publication set of climate change research. We are interested in whether Twitter data are able to reveal topics of public discussions which can be separated from research-focused topics. We find that the most tweeted topics regarding climate change research focus on the consequences of climate change for humans. Twitter users are interested in climate change publications which forecast effects of a changing climate on the environment and to adaptation, mitigation and management issues rather than in the methodology of climate-change research and causes of climate change. Our results indicate that publications using scientific jargon are less likely to be tweeted than publications using more general keywords. Twitter networks seem to be able to visualize public discussions about specific topics. 相似文献

This work analyses the perception and practice of sharing, reusing, and facilitating access to research data in the field of food science and technology. The study involved the coordination of a focus group discussion and an online survey, to understand and evince the behaviour of researchers regarding data management in that field. Both the discussion group and the survey were performed with researchers from several institutes of the Spanish National Research Council. The lack of a data sharing culture, the fear of being scooped, and confusion between the concepts of the working plan and the data management plan were some of the issues that emerged in the focus group. Respondents' previous experience with sharing their research data has been mainly in the form of appendices to peer‐reviewed publications. From the survey (101 responses), the most important motivations for publishing research data were found to be facilitating the reproducibility of the research, increasing the likelihood of citations of the article, and compliance with funding body mandates. Legal constraints, intellectual property, data ownership, data rights, potential commercial exploitation, and misuse of data were the main barriers to publishing data as open data. Citation in publications, certification, compliance with standards, and the reputation of the data providers were the most relevant factors affecting the use of other researchers' data. Being recent or recently updated, well documented, with quality metadata and ease of access were the most valued attributes of open research data. 相似文献

This paper provides an overview of the needs and threats for digital preservation and summarizes the findings from project PARSE.Insight. This project, co‐funded by the EU, contains one of the first large worldwide surveys about digital preservation including most players of the STM information chain: researchers, libraries, data managers, publishers, and research funders. One of the conclusions is that in the present data deluge, it is extremely important that all players in the information chain work together on proper digital preservation of all research output, to ensure its future usability, understandability, and authenticity. This poses a new role for publishers who can ensure better discoverability and citability via good linking and integration of data and publications. 相似文献

Studies investigating data sharing from a world perspective are seemingly rare. By employing a quantitative design,this systematic review investigates and presents a comprehensive account of factors hampering data sharing at three levels of the global research hierarchy (individual, institutional and international). The study analyses secondary data extracted from 105 publications (n=105). Journal publishers and research grant organisations are key players in promoting data sharing activities by formulating, adopting and implementing policies on data sharing. Despite concerted efforts to promote data sharing, various factors frustrate these initiatives; they include lack of time and data misappropriation (individual level); data sharing training, absence of compensation and unfavourable internal policies (institutional level); and weak policies, ethical and legal norms, lack of data infrastructure and interoperability issues (international level). To counter these challenges, there is a need for research stakeholders to recognise researchers who share data through data citations, acknowledgement and incentives; invest in infrastructure, conduct training and advocacy programs; formulate stringent and fair policies. Data sharing will only become a success if research stakeholders apply equal efforts in managing data to that of research publications in general. The study offers a unique and comprehensive account of factors hampering data sharing from a global perspective. Solutions suggested could be adopted by research stakeholders in their efforts to enhance data sharing activities at various research levels. 相似文献

The problem of citation impact assessments for recent publication years in institutional evaluations
Lutz Bornmann 《Journal of Informetrics》2013,7(3):722-729
Bibliometrics has become an indispensable tool in the evaluation of institutions (in the natural and life sciences). An evaluation report without bibliometric data has become a rarity. However, evaluations are often required to measure the citation impact of publications in very recent years in particular. As a citation analysis is only meaningful for publications for which a citation window of at least three years is guaranteed, very recent years cannot (should not) be included in the analysis. This study presents various options for dealing with this problem in statistical analysis. The publications from two universities from 2000 to 2011 are used as a sample dataset (n = 2652, univ 1 = 1484 and univ 2 = 1168). One option is to show the citation impact data (percentiles) in a graphic and to use a line for percentiles regressed on ‘distant’ publication years (with confidence interval) showing the trend for the ‘very recent’ publication years. Another way of dealing with the problem is to work with the concept of samples and populations. The third option (very related to the second) is the application of the counterfactual concept of causality. 相似文献

This paper presents the results of a new method that is applied for a multidimensional analysis of the publications, patents, and authors of the related arrays of documents that are prepared under thematically similar projects that are supported by a science foundation. The contribution to and impact of various groups of scientists on the results of these projects are analyzed. Specifically, it is established that Russian scientists that work abroad (expatriates) play an important role in improving the scientific level of domestic research and in engaging domestic and foreign scientists in such research investigations. The data on the distribution of publications, patents, and authors by domestic and foreign organizations and cities, as well as by subjects of the Russian Federation and foreign countries, are obtained and analyzed. 相似文献

The National Technical Information Service (NTIS) is a self-supporting agency of the U.S. Department of Commerce that actively collects, organizes, and distributes technical information generated by United States and foreign governments in all areas of science and technology. There are two million titles in the NTIS permanent archives, some of which date as far back as 1945, and last year NTIS added 63,000 new titles to its collection. The entire collection is available at any time - whether a report dates from 20 years ago or last month. In addition, NTIS provides government generated computer software and computerized data files on both tape and diskette through its Federal Computer Products Center. To keep pace with technology transfer activities, the NTIS Center for the Utilization of Federal Technology licenses Federal inventions and makes them available to private industry and prepares and issues a number of publications, catalogs, and directories announcing Federal technologies and resources. In the area of foreign technology, NTIS has recently increased its holdings - up to a third of the reports entering the collection are now from foreign sources. 相似文献

SUMMARY The author discusses a wide range of new developments in Ukrainian libraries that affects library acquisitions. New strategies are now required for obtaining library materials due to the inadequacy of obligatory deposit and changes in bibliographic control of new publications. Libraries are actively developing computer and Internet technologies, including websites, online catalogs, access to databases, sites linking to online resources, and collections of digitized full-text material. A number of libraries have recently begun implementing virtual reference services. A new professional journal, whose title translates as Library Forum of Ukraine, has arisen to address all aspects of librarian-ship. 相似文献

Given the recent trend in bibliometrics and information science to use increasingly complex statistical methods, it is necessary to have powerful toolboxes to work with data from Web of Science (Thomson Reuters). We developed such a toolbox with four specific commands for the statistical software package Stata. These commands refer to (1) the import of downloads from Web of Science to Stata, (2) the preprocessing of address information from authors of publications in the downloaded set, (3) the geocoding of address information, and (4) the calculation of the minimum and maximum distance between several co-authors of a single paper. An advantage of developing commands for an established and comprehensive statistical software package (like Stata) is that a large number of further commands are available for the analysis of bibliometric data. We will describe some of these useful commands as well. 相似文献
