In tandem with the rapid globalisation of science, spatial scientometrics has become an important research sub-field in scientometric studies. Recently, numerous spatial scientometric contributions have focused on the examination of cities’ scientific output by using various scientometric indicators. In this paper, I analyse cities’ scientific output worldwide in terms of the number of journal articles indexed by the Scopus database, in the period from 1986 to 2015. Furthermore, I examine which countries are the most important collaborators of cities. Finally, I identify the most productive disciplines in each city. I use GPS Visualizer to illustrate the scientometric data of nearly 2200 cities on maps. Results show that cities with the highest scientific output are mostly located in developed countries and China. Between 1986 and 2015, the greatest number of scientific articles were created in Beijing. The international hegemony of the United States in science has been described by many studies, and is also reinforced by the fact that the United States is the most important collaborator to more than 75% of all cities. Medicine is the most productive discipline in two-thirds of cities. Furthermore, cities having the highest scientific output in specific disciplines show well-defined geographical patterns. 相似文献

The preferences of the authors of Chinese library and information science (LIS) journal articles in citing Internet sources were investigated using eight premium Chinese LIS journals from Chinese Social Sciences Citation Index (the observation group) and 10 journals in other disciplines (the control group) from the same database from 1999 to 2008. A total of 252,881 citations were analyzed in terms of count, domain name, and citing purposes. The results show that (a) in comparison to the disciplines in the control group, LIS articles in Chinese journals indicated a strong preference for citing Internet sources, and this preference is increasing; (b) LIS articles did not seem to discriminate against domain names when citing Internet sources; and (c) LIS articles cited more Internet sources as evidence to support research results and conclusions. Excessive dependency on Internet sources may raise concerns over the quality, research ethics, and credibility of research publications. Chinese LIS researchers should place more emphasis on the disadvantages of Internet sources as supporting material. Guidelines and criteria to help researchers, journal editors, students, and librarians assess information on the Web need to be developed. 相似文献

Although scholarly articles play an important role in the work life of academics, specific patterns of seeking and reading scholarly articles vary. Subject discipline of the reader influences many patterns, including amount of reading, format of reading, and average time spent per reading. Faculty members in different disciplines exhibit quite distinct patterns of reading. Medical/health faculty read more than others and mainly for current awareness purposes, while engineering faculty spend more time on average per article reading, and they also read more for research. Other factors that influence some reading patterns include work responsibilities (weighted towards more teaching or more research), age (young faculty are more likely to read on-screen from the open Web) and productivity of the reader, and purpose of the reading (readings for research and writing are more likely to be from a library collection). The ability to predict scholarly article seeking and reading patterns will assist journal editors, publishers, and librarians design better, more targeted journal systems and services. 相似文献

This paper discusses the results of statistical research on the information massif of the “Abstract Journal” DB (of the Republic of Kazakhstan) with a volume of about 50000 documents, which was carried out based on a number of scientometric indices. The types of journals, thematic structure of the AJ DB and prospective directions for investigations are designated. The leading journals on the themes of the series of the abstract journal are revealed. The averaged ratio between the scientific articles of the Kazakhstan scientists published in Kazakhstan, CIS-countries and far-abroad countries is determined to be 80: 5: 1. The main themes of publications in the English language relate to chemistry, physics, and mathematics. The works in various fields of Kazakhstan science are presented in Russian journals. 相似文献

Knowledge about the information needs and seeking behavior of scientists could play a vital role in meeting their information needs effectively. Libraries can use this knowledge for re-orienting their collections and facilities to attune them to the needs of the scientific community. This study explores information needs and seeking behavior of Malaysian agricultural scientists. It was found that research scientists spent 16% of their office time on reading and literature searching, whereas academicians spent 9.3% of their time for this purpose. The study also revealed that scientists preferred using primary sources of information, particularly journal and review articles. Informal communication with professional colleagues was also considered important for exchanging current research information. A large number of the participants felt that they had not been keeping in touch with scientific literature due to deficient library collections and services. This article recommends that science and technology libraries should periodically survey the information needs of their users, assess their collections and facilities, and strengthen their promotional activities. 相似文献

The development of scientometric indicators and methods for evaluative purposes, requires a multitude of assumptions, conventions, limitations, and caveats. Given this, we cannot permit ambiguities in the key concepts forming the basis of scientometric science itself, or research assessment exercises would rest on quicksand. This conceptual work attempts to spell out some principles leading to a clear definition of “impact” of research, and above all, of the appropriate scientometric indicator to measure it. The aim is to stimulate a discussion aimed at a definitive convergence on the meaning and measurement of a fundamental concept of the scientometric science. 相似文献

Multidisciplinary cooperation is now common in research since social issues inevitably involve multiple disciplines. In research articles, reference information, especially citation content, is an important representation of communication among different disciplines. Analyzing the distribution characteristics of references from different disciplines in research articles is basic to detecting the sources of referred information and identifying contributions of different disciplines. This work takes articles in PLoS as the data and characterizes the references from different disciplines based on Citation Content Analysis (CCA). First, we download 210,334 full-text articles from PLoS and collect the information of the in-text citations. Then, we identify the discipline of each reference in these academic articles. To characterize the distribution of these references, we analyze three characteristics, namely, the number of citations, the average cited intensity and the average citation length. Finally, we conclude that the distributions of references from different disciplines are significantly different. Although most references come from Natural Science, Humanities and Social Sciences play important roles in the Introduction and Background sections of the articles. Basic disciplines, such as Mathematics, mainly provide research methods in the articles in PLoS. Citations mentioned in the Results and Discussion sections of articles are mainly in-discipline citations, such as citations from Nursing and Medicine in PLoS. 相似文献

How does the collaboration network of researchers coalesce around a scientific topic? What sort of social restructuring occurs as a new field develops? Previous empirical explorations of these questions have examined the evolution of co-authorship networks associated with several fields of science, each noting a characteristic shift in network structure as fields develop. Historically, however, such studies have tended to rely on manually annotated datasets and therefore only consider a handful of disciplines, calling into question the universality of the observed structural signature. To overcome this limitation and test the robustness of this phenomenon, we use a comprehensive dataset of over 189,000 scientific articles and develop a framework for partitioning articles and their authors into coherent, semantically related groups representing scientific fields of varying size and specificity. We then use the resulting population of fields to study the structure of evolving co-authorship networks. Consistent with earlier findings, we observe a global topological transition as the co-authorship networks coalesce from a disjointed aggregate into a dense giant connected component that dominates the network. We validate these results using a separate, complimentary corpus of scientific articles, and, overall, we find that the previously reported characteristic structural evolution of a scientific field's associated co-authorship network is robust across a large number of scientific fields of varying size, scope, and specificity. Additionally, the framework developed in this study may be used in other scientometric contexts in order to extend studies to compare across a larger range of scientific disciplines. 相似文献

Several studies have attempted to reveal the real scope, completeness, and consistency of journal coverage across time in abstracting/indexing publications. Online and CD-ROM databases make easier the collection of posting information for journals to determine the traits of their coverage but do not eliminate entirely the tedium of manual methods. Difficulties are compounded when multiple databases are used to compare the journal coverage and overlap of several databases for an extended time period. This article discusses the use of advanced search commands and the Journal Name Finder database of DIALOG, to simplify the collection and processing of posting information for 42 prestigious library and information science (LIS) serials between 1966 and 1996 in six databases. It presents the major types of deficiencies in journal coverage that may yield very incomplete search results and may distort the results of bibliometric and scientometric studies. The methodology allows the creation of various subsets by the versatile combination of journal titles, time periods and databases, and encourages longitudinal data collection and comparison of variously aggregated datasets. It can be used for profiling the journal coverage in the evaluation of databases in support of bibliometric research, database acquisition, and licensing decisions. 相似文献

Today’s scientific research is an expensive enterprise funded primarily by taxpayers’ and corporate groups’ monies. All nations want to discover fields of study that promise to create future industries, and dominate these by building up and securing scientific and technological expertise early. However, the conversion of scientific leadership into market dominance remains very much an alchemy. To gain insights into how science becomes technology, we focused on graphene (which shows promise in batteries, sensors, flexible displays and other technologies) as a case study. In particular, we asked whether research on the material is on track to deliver all its technological promises. To answer this question, we analyzed in this paper bibliometric records of scientific journal publications and patents related to graphene. While performing straightforward analyses at the aggregate and temporal level to do so, we stumbled upon evidences that suggest ‘Golden Eras’ of graphene science and technology in the recent past. To confirm this unexpected finding, we developed a novel simulation-based method to determine how the interest levels in graphene science and technology change with time. We then found compelling evidences that these interest levels peaked in 2010 and 2012 respectively, despite the continued growth of journal and patent publications in this area. This suggests that publication numbers in a research topic could sometimes give rise to false positives concerning its importance. 相似文献

科学-技术关联是指技术创新系统与科学研究系统之间的知识传递关系。探测科学-技术关联的情报学方法是:计量"论文-专利"互引信息,用专利所属的4位IPC类目与论文所属的学科之间的对应关系来反映科学-技术关联。此方法中存在两方面问题:一方面,论文被笼统地视为基础科学的代表,忽略了自然科学体系的"基础科学-技术科学-工程科学"的层级结构;另一方面,IPC类目以"功能"为分类原则且粒度过粗,难以与科学学科合理对应。对科学端的学科层级划分问题和技术端的4位IPC类目细化问题进行研究,对探测科学-技术关联的情报学方法进行改进,并以2006-2009年间的美国催化技术专利和与之具有互引关系的论文为样本进行实验,实验结果反映出更精细的学科-领域对应关系,呈现出更清晰的科学-技术关联图景。 相似文献

Research topic studies have gained popularity in many disciplines, including library and information science (LIS). However, the lack of representation of library science and librarianship in literature indicates a research bias due to the preset methodology parameters, which are commonly based on impact factor scores in the Journal Citation Report of Thomson Reuters. In research, the authors utilize an improved selection criterion of journals and author-supplied keyword clustering and analysis technique to study the most recent ten years of LIS journal publications. This article presents a clear picture of popular research topics in seminal literature to help practicing librarians and library science scholars gain a better understanding and considerable prediction on the research trends in the LIS field. 相似文献

This paper provides the results of a two‐year investigation into the use of e‐journals by the UK research community. Log analysis, questionnaires, interviews, and observation were used to collect the information. The results are presented in a FAQ format to make the key findings accessible. The main findings are that journals have become central to most disciplines, and that the e‐form has become the prime means of access. The results for history suggest that the old scholarly communication mantras (scientists primarily communicate through articles, historians through monographs) are rapidly breaking down. Indeed, all researchers seem addicted to journal content. Research without this resource now seems unthinkable; journals are a researcher's lifeblood. Gateway services, hugely popular in science, are re‐intermediating the broken chain between publisher and reader; they are the new librarians. 相似文献

The paper presents a statistical and subjective review of the journal articles on various aspects of library and information services in Pakistan. Only the articles published in the journals outside Pakistan are included. Articles are selected from four abstracting services, i.e. LISA, ISA, LSA, and ERIC. Authorship characteristics of 97 articles are analysed and compared with the previous studies of LIS periodicals. Authorship details include collaboration, occupation, affiliation, and the author's country. Other publication details of the articles include year, language, journal, and the country of publication. The findings show that library science teachers write more than the other professionals and the most popular subject is the library and information science education. Library science faculty at Karachi University contributes more articles in international journals. The articles are mostly published in English language journals and in English speaking countries, i.e. UK and USA.International Information and Library Reviewpublished more articles on this topic. Problems in library research in Pakistan are discussed and recommendations are made. A brief review of the articles is given according to 16 major subjects. A bibliography of the articles reviewed is also compiled. 相似文献
