With the rapid globalization of science, mobility is perceived as an important driver of scientific progress and innovation success. However, we have little knowledge about whether and how scientists’ mobility influences their career development, especially scientists’ productivity and collaboration. In this case study, using the data on 62,330 scientists, the Chinese computer scientists who published at least one computer science paper and published no fewer than 10 papers in total from 2000 to 2012, we apply difference in differences models in conjunction with PSM methods to show the effect of domestic mobility (i.e., moving inside China) on scientists’ research quantity and quality by distinguishing the direction of mobility. In contrast to the existing literature that documents a short-term negative effect due to adaption costs or disruption of routines and social capital, we do not observe an initial detrimental impact of following moves on productivity and collaboration, even for non-upward moves. We further find that mobility leads to increased collaboration with new partners without dampening scientists’ collaboration with previous collaborators. However, scientists have a higher probability of collaborating with new collaborators, as evidenced by the decreased share of previous collaborators to the total co-authors after they move. The findings of this case study imply that the benefits of mobility might outweigh its costs and that mobility improves scientists’ productivity and collaboration for prolific scientists in emerging countries. 相似文献

Scientific production is steadily growing, exhibiting 4% annual growth in publications and 1.8% annual growth in the number of references per publication, together producing a 12-year doubling period in the total supply of references, i.e. links in the science citation network. This growth has far-reaching implications for how academic knowledge is connected, accessed and evaluated. Against this background, we analyzed a citation network comprised of 837 million references produced by 32.6 million publications over the period 1965–2012, allowing for a detailed analysis of the ‘attention economy’ in science. Our results show how growth relates to ‘citation inflation’, increased connectivity in the citation network resulting from decreased levels of uncitedness, and a narrowing range of attention – as both very classic and very recent literature are being cited increasingly less. The decreasing attention to recent literature published within the last 6 years suggests that science has become stifled by a publication deluge destabilizing the balance between production and consumption. To better understand these patterns together, we developed a generative model of the citation network, featuring exponential growth, the redirection of scientific attention via publications’ reference lists, and the crowding out of old literature by the new. We validate our model against several empirical benchmarks, and then use perturbation analysis to measure the impact of shifts in citing behavior on the synthetic system's properties, thereby providing insights into the functionality of the science citation network as an infrastructure supporting the memory of science. 相似文献

Bern's gender schema theory (Bern 1981, 1983, 1993) provides a useful framework for examining the influence of women scientist role models on girls’ perceptions of science and scientists. The purpose of this paper is (1) to describe how Bern's gender schema theory serves as a framework for guiding future research, (2) to examine the fundamental premises of Bern's gender schema theory as they relate to the processing of information about science and gender roles, and (3) to identify key conditions and criteria from gender schema theory to guide the design of television programs that use role models to reduce gender‐stereotyping of science. 相似文献

This article reviews the extraordinary growth in the scientific literature that has resulted from increased federal expenditures in the past decade or two. The article further notes that the impact of the knowledge explosion has impinged on the Health Sciences Library as well as on the individual scientist who needs access to the information. A strong plea is made for the librarian to assume a more active role in: doing internal research with respect to how best to use the library as a tool in the dissemination of new information; educating newcomers to the field of library science with respect to the management of scientific information; and converting the library from a passive to an active instrument in disseminating the scholarly record to and among those who require access to it. Medical center administrators are reminded that if the librarian succeeds in these ventures then he will fulfill all of the research, teaching, and service requirements ordinarily made of other academic departments and, in turn, should be rewarded with departmental status for the library. 相似文献

Governmental initiatives around scientific policy have progressively raised collaboration to priority status. In this context, a need has arisen to broaden the traditional approach to the analysis and study of research results by descending to the group or even the individual scale and supplementing the output-, productivity-, visibility- and impact-based focus with new measures that emphasize collaboration from the vantage of structural analysis. To this end, the present paper proposes new hybrid indicators for the analysis and evaluation of individual research results, popularity and prestige, that combine bibliometric and structural aspects. A case study was conducted of the nine most productive departments in Carlos III University of Madrid. The findings showed hybridization to be a tool sensitive to traditional indicators, but also to the new demands of modern science as a self-organized system of interaction among individuals, furnishing information on researchers’ environments and the behaviour and attitudes adopted within those environments. 相似文献

This essay provides an unpalatable perspective on classifying the reluctance of authors, editors or publishers to correct their erroneous literature as being unethical. Authors who publish papers that carry errors and who take laurels for such publications, but who then fail to correct reported errors at a post-publication stage should be classified as unethical, and their act or irresponsibility as misconduct. Similarly, editors and publishers who fail to revise erroneous literature when claims are factually correct, independent of the volume of claims, are also in violation of their codes of conduct and professional responsibilities towards the scientific community and society. This essay provides a critical outlook on this issue which has begun to plague the post-publication movement in science, and which deserves urgent attention and focus. 相似文献

While researchers with retracted papers – publications that are withdrawn because of significant errors or scientific misconduct – carry a permanent stain on their publishing records, understanding the causes and initiators of such retractions can shed a different light on the matter. This paper, based on a random sample of 2,046 retracted papers, which were published between 1975 and 2019, extracted from Retraction Watch and the websites of major publishers, shows that 53% of the retraction notices do not specify who initiated the retraction. Nearly 10% of the retraction notes either omit or do not contain information related to reasons for retractions. Furthermore, most of the retracted papers in our sample have no limitation section; those who do are commonly unhelpful or irrelevant. The results carry three implications for scientific transparency: retraction notices need to be more informative; limitation sections ought to be a required and even an open section of all published articles; and finally, promoting ‘heroic acts’ in science can positively change the current publishing culture. 相似文献

This paper attempts to shed some light on the scientific communication behavior of Arab authors in library and information science by studying the characteristics of the literature used by these authors. A bibliometric study by way of citation analysis was conducted on the articles published from 1978 to 1988 in Maktabat Al-Idarah, an elite Arab scholarly journal in the field. It was concluded from this study that English literature is the main source of information for Arab authors in library and information science. They rely on English literature that is between 5 and 15 years of age more than on their own literature and use books more than any other form of publication. They cover almost all areas of the field with special emphasis on technical services as represented by cataloging, classification and aquisition, library administration and library education. Local materials published in their own country were also important. 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

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

This paper cites statistical data describing the tendencies in Russian scientists’ publishing activity in the period from 1993 to 2006 according to the DB Web of Science (WOS). An important result of the research is the fact that about 50% of the papers written by Russian authors were published in foreign scientific journals used to prepare the WOS. This is a demonstration that Russian science is highly integrated into international science. To conduct a comparative analysis of the scientific productivity of the Russian scientists we used statistics obtained from the SCOPUS information system and presented in the SJR portal. 相似文献

Suppose there is a scientist that writes a paper for a peer-reviewed journal. How likely is it that a natural disaster will terminate, change, suspend or discontinue some aspect of this editorial process? To answer this question, the aim of present study was to determine the effects of a natural disaster on progress in materials science research. The Tsunami event in Japan and materials science are well suited to serve as a case study for both the development and application of a system to evaluate the Academic Research Output immediately after a natural disaster. In particular, the analysis focused on the short-term impacts of Japan's triple disaster – earthquake, Tsunami, and nuclear accident (11 March, 2011) – on the Academic Research Output in materials science subject from three different areas: Sendai (Miyagi Prefecture), Tsukuba (Ibaraki Prefecture) and Kyoto (Kyoto Prefecture). The last one has been used as an internal reference standard (normal/non-disaster situation) for the comparison. A geographical cluster-based study was conducted between 09 February and 10 April 2011. Consistent with the hypothesis that a disaster might slow down knowledge production, the conclusion showed that the Japan's triple disaster strongly influenced the Academic Research Output of papers in the selected field of science. Using statistical data, these findings show that the number of submitted papers and the cumulative number of authors contributing to the field of materials science decreased immediately after the March 11th events in the areas affected by disaster. 相似文献
