China's status as a scientific power, particularly in the emerging area of nanotechnology, has become widely accepted in the global scientific community. The role of knowledge spillover in China's nanotechnology development is generally assumed, albeit without much convincing evidence. Very little has been investigated on the different mechanisms of knowledge spillover. Utilizing both cross-sectional data and longitudinal data of 77 Chinese nanoscientists’ publications, this study aims to differentiate individual effects from the effect of international collaboration on the research performance of Chinese researchers. The study finds evidence in support of the “birds of a feather flock together” argument – that China's best scientists collaborate at international level. It also finds that collaboration across national boundaries has a consistently positive effect on China's nano research quality with a time-decaying pattern. Language turns out to be the most influential factor impacting the quality or visibility of Chinese nano research. Policy implications on research evaluation, human capital management, and public research and development allocation are also discussed in the end.  相似文献

In the previous literature, no clear conclusions have been reached about the effect of gender differences on research performance (RP) in science, as measured by publication productivity, number of citations, and academic awards. Meanwhile, a gap also exists in the research regarding gender differences in international academic collaboration. To complement the existing literature, this study investigated the achievements of scientists engaged in international academic collaboration, which places heavy demands on language and communication skills and in which female scientists appear to have more advantages than male scientists. We investigated the effect of international collaboration carried out by chemists from China’s Project 985 universities and the Chinese Academy of Sciences and compared the extent to which the international collaboration improved female and male scientists’ academic performance. The results indicated that, compared to male scientists, female scientists performed better and significantly improved their academic performance through international collaboration. This conclusion was valid for different periods throughout chemists’ academic careers. The policy implications are discussed at the end of this study.  相似文献

The present work investigates the relations between amplitude and type of collaboration (intramural, extramural domestic or international) and output of specialized versus diversified research. By specialized or diversified research, we mean within or beyond the author’s dominant research topic. The field of observation is the scientific production over five years from about 23,500 academics. The analyses are conducted at the aggregate and disciplinary level. The results lead to the conclusion that in general, the output of diversified research is no more frequently the fruit of collaboration than is specialized research. At the level of the particular collaboration types, international collaborations weakly underlie the specialized kind of research output; on the contrary, extramural domestic and intramural collaborations are weakly associated with diversified research. While the weakness of association remains, exceptions are observed at the level of the individual disciplines.  相似文献

The analysis of research collaboration by field is traditionally conducted beginning with the classification of the publications from the context of interest. In this work we propose an alternative approach based on the classification of the authors by field. The proposed method is more precise if the intended use is to provide a benchmark for the evaluation of individual propensity to collaborate. In the current study we apply the new methodology to all Italian university researchers in the hard sciences, measuring the propensity to collaborate for the various fields: in general, and specifically with intramural colleagues, extramural domestic and extramural foreign organizations. Using a simulation, we show that the results present substantial differences from those obtained through application of traditional approaches.  相似文献

Faculty–library collaboration paves the way to make students information literate and finally to make them life-long learners. In traditional universities, the faculty–library collaboration is an emerging phenomenon as these two entities are driven by separate agendas; teaching and providing services. Rapid development in information and communication technologies has built a platform for these two institutions to work collaboratively and for making synergies. The purpose of this paper is to describe the conceptual model for faculty–library collaboration based on the extensive literature review and some strategies used by librarians at University of Colombo to collaborate with the academics.  相似文献

ABSTRACT

Drawing on Buckingham’s observation that academic research either has to become public knowledge or its originators must have a high visibility in the public realm before their research can find inclusion into policymaking processes, this article offers a variety of examples of how academics have managed to bridge the gap between media and communication policy scholarship and policymaking. Contrary to the long-standing belief that policy impact is extremely difficult and rare to achieve, we argue that junior scholars have many opportunities to have their work become part of the policymaking process through new forms of conversation, collaboration, coalition-building, changing perceptions of public knowledge, and a more conceptual understanding of impact.  相似文献

As scientific collaboration has become more common with increased representation of female scholars, the effects of inter-gender collaboration have attracted more attention. However, scholars have not reached a consensus on the relationship between inter-gender collaboration and research performance. Empirical evidence at the scholar level has also been rare. Therefore, based on the ratio of the opposite sex in collaboration partners, this study reveals the influence of participating in inter-gender collaborations on research performance for scholars. Grouped regression was employed to test gender differences in this effect. The effect of partners’ academic levels was also investigated to account for potential gender differences. The results indicated that inter-gender collaboration had a positive effect on research performance for scholars. Grouped regressions also showed that collaborating with more inter-gender partners exerted a significantly negative effect on the research performance of female scholars, while it had a positive effect for male scholars. The negative effect on female scholars were found to be strengthened if the partners were at a high academic level. This study is helpful to understand inter-gender collaboration in depth, and further reveals the gender differences in scientific collaboration.  相似文献

Scientific collaboration has become an important approach for knowledge production and innovation and has received wide attention. Although gender, a demographic characteristic of scientists, has been found to influence scientific collaboration, little research has associated gender with continuous collaboration. In the current study, we classified collaboration pairs by the genders of the two collaborators and explored the relationships among gender composition, collaboration continuity, and citation impact using regression analyses. Female scholars were found to limit continuity for the collaboration pair. The results also showed that inter-gender collaborations were less continuous than intra-gender collaborations after considering the gender difference in individual persistence. In addition, we showed that the relationship between continuity and citation impact was significantly positive, and was stronger if the collaboration pairs included female scholars. This study provides a deeper understanding of gender-related scientific collaboration. It also provides continuity-related suggestions for researchers in inter-gender collaborations.  相似文献

The fundamental research question being pursued in this study is what influences the degree of international scientific collaboration among Turkish scientists? While the study has been illuminated by bibliometrics, the research study is largely exploratory and qualitative. Email questionnaire surveys and semi-structured interviews were employed to collect data from Turkish scholars. According to the findings, both external (uncontrollable) factors (e.g., institutional, economic, and governmental factors) and internal factors (e.g., motivation, ambition, trust, and hope) play roles in the international collaboration behavior of Turkish scholars. It is expected that this research will contribute to the understanding of Turkey’s international scientific collaboration processes pertaining to technology, economic, strategic, and cultural policy factors. Also, the analytical framework of this study may be useful for analyzing other developing countries that have a similar scientific and demographic context to Turkey’s.  相似文献

International scientific collaboration has been the dominant driving force for promoting scientific and technological advancement. However, current international scientific collaboration analysis and evaluation mainly concentrate on the exploration of international collaboration network; hence, an evaluation method of international scientific collaboration is yet to be formed. In this paper, we take the dye-sensitized solar cells (DSSCs) as an empirical object and combine the international collaboration network with geographic information, which we call the International Collaboration Map, to display the international collaboration situations among countries or regions worldwide (inter-country collaboration), the collaborations among countries or regions within each continent (intra-continent collaboration), and the collaborations among continents (inter-continent collaboration) from different angles. Based on the thought of fractional count, this study introduces the indicators of collaborative country rank, international collaboration width, and international collaboration activity; the study employs the International Collaboration Activity Index (ICAI) to comprehensively measure the degree of countries or regions international collaboration at the country or region level. It systematically evaluates the differences between the active degree of relevant countries or regions in collaborative research. We use correlation analysis among the five sub-criterions and verify the rationality of index construction. K-means clustering analysis is undertaken among 84 countries or regions in the DSSCs field. The results show the formation of three groups, each with their unique international collaboration features.  相似文献

The aim of this paper is to explore the collaboration of female inventors, how it affects their innovation production and whether it influences their innovation impact. Empirical knowledge of how inventors collaborate in co-patenting collaborations holds an important key to innovation development. In this article, we report on an analysis of international inventors and patents granted by the European Patent Office (EPO) between 1978 and 2019. We investigate the structure of inventors’ networks—particularly those of female inventors—over time using social network analysis and address the gender patterns of collaboration. It can be observed that while female inventors’ overall involvement in patenting activity is not that high, the share of female inventors increases over the time period in question from 1.2% to 8.9%. We also estimate panel data regressions on the number of patents and the citation rates of the patents at an individual level. Our results show that although all inventors benefit from a more central network position within the co-patenting network in terms of their innovation output, the positive influence is greater for male inventors than female inventors. In addition, when inventors collaborate with inventors from more diversified countries and regions they contribute to more patents and their patents are more cited.  相似文献

Book editors in the social sciences and humanities play an important role in their fields but little is known about their typical publication and collaboration patterns. To partially fill this gap, we compare Flemish editors and other researchers, in terms of career stage, productivity, publication types, publications with domestic and international collaboration as well as the number of (international or all) unique co‐authors, co‐editors and associated book chapter authors. The results show that editors are mostly established researchers, especially in the social sciences, produce more book chapters and monographs than do other researchers, and are more productive. Nevertheless, editors collaborate less than do other researchers, both in terms of publications and in number of co‐authors. Including book chapter authors in the editors' collaboration networks makes those networks substantially larger, demonstrating that editors do not mainly call upon authors from their existing collaboration network when choosing book chapter authors in the edited books. Finally, editors seem to co‐author with their book chapter authors slightly more often after the publication of the edited book than before.  相似文献

In the past few decades, there has been increasing interest in public-private collaboration, which has motivated lengthy discussion of the implications of collaboration in general, and co-authorship in particular, for the scientific impact of research. However, despite this strong interest in the topic, there is little systematic knowledge on the relation between public-private collaboration and citation impact. This paper examines the citation impact of papers involving public-private collaboration in comparison with academic research papers. We examine the role of a variety of factors, such as international collaboration, the number of co-authors, academic disciplines, and whether the research is mainly basic or applied. We first examine citation impact for a comprehensive dataset covering all Web of Science journal articles with at least one Danish author in the period 1995–2013. Thereafter, we examine whether citation impact for individual researchers differs when collaborating with industry compared to work only involving academic researchers, by looking at a fixed group of researchers that have both engaged in public-private collaborations and university-only publications. For national collaboration papers, we find no significant difference in citation impact for public-only and public-private collaborations. For international collaboration, we observe much higher citation impact for papers involving public-private collaboration.  相似文献

This study explores the impact of different collaboration modes on the cited frequency of publications. Though several studies have obtained some research results, most of them exploit association or regression-based methods, which may not lead to causal conclusions. To overcome the above challenges, we use the Propensity Score Matching (PSM) method to analyze and compare the citation frequencies resulting from four groups of collaboration models: international versus domestic, international multilateral versus international bilateral, domestic inter-organizational versus domestic intra-organizational, and domestic multi-author versus domestic single-author. More specifically, we conduct this analysis by exploring the publications with three computer science subfields from the Web of Science (WoS) database. The experimental results show that international collaboration, especially international multilateral collaboration, has a significant role in increasing the frequency of citations to scientific publications, showing that internationalization and collaboration are critical factors in the growth of the impact of the papers. Among national co-publications, collaborative publications within national organizations receive a higher citation impact. Multi-author collaborations significantly increase citation frequency compared to single-author publications. Our heterogeneity analysis across the different subfields of the computer science domain finds that the treatment effects for the three subfields differ modestly and mostly significant from the whole sample. Moreover, besides the implications for developing research policy and scientist collaboration, our study can capture the causal effect between author collaboration patterns and citation frequency to reveal their causal effects.  相似文献

The difference between the advanced and developing countries in the matter of access to information for research has been continually increasing. The advent of the Internet and electronic sources of information has not only exacerbated the gap but also led to the exclusion of developing country researchers from taking part as equal partners in publishing, refereeing, and in international collaboration. If handled imaginatively, the very same technologies can help bridge the information gap between the rich and the poor countries and help improve research productivity worldwide. Many initiatives that are already in place are described and suggestions are given on steps to be taken by developing country researchers.  相似文献

The relevance of international research collaboration (IRC) in bolstering intellectual capital, increasing embeddedness in networks, and promoting innovation has been acknowledged by scientists and policymakers. However, large–scale studies involving different scientific domains and periods aimed at exploring the factors that influence IRC are missing, which could deepen our understanding of the factors affecting IRC.Based on a novel dataset of 193 countries over three periods, 1990–1999, 2000–2009 and 2010–2018, we have examined the impact of geographical, socioeconomic, political, cultural, intellectual, and excellence distances on the propensity to engage in IRC at the global level, by scientific domain and over time.In general, all the distances considered obstruct IRC, with geographical and cultural distance emerging as the barriers with the highest impact. Two exceptions are worthwhile noting: excellence distance fosters IRC in the Medical & Health Sciences (MHS) and intellectual distance fosters IRC in the Agricultural Sciences (AS).At the global level, the negative impact of socioeconomic, political, and intellectual distances on IRC has increased over time, whereas the negative impact of geographical and cultural distances has decreased.  相似文献
