The debate on the role of women in the academic world has focused on various phenomena that could be at the root of the gender gap seen in many nations. However, in spite of the ever more collaborative character of scientific research, the issue of gender aspects in research collaborations has been treated in a marginal manner. In this article we apply an innovative bibliometric approach based on the propensity for collaboration by individual academics, which permits measurement of gender differences in the propensity to collaborate by fields, disciplines and forms of collaboration: intramural, extramural domestic and international. The analysis of the scientific production of Italian academics shows that women researchers register a greater capacity to collaborate in all the forms analyzed, with the exception of international collaboration, where there is still a gap in comparison to male colleagues. 相似文献

The growing complexity of scientific challenges demands increasingly intense research collaboration, both domestic and international. The resulting trend affects not only the modes of producing new knowledge, but also the way it is disseminated within scientific communities. This paper analyses the relationship between the “degree of internationalization” of a country’s scientific production and that of the relevant citing publications. The empirical analysis is based on 2010-2012 Italian publications. Findings show: i) the probability of being cited increases with the degree of internationalization of the research team; ii) totally domestic research teams tend to cite to a greater extent totally domestic publications; iii) vice versa, publications resulting from international collaborations tend to be more cited by totally foreign publications rather than by publications including domestic authors. These results emerge both at overall and at discipline level. Findings might inform research policies geared towards internationalization. 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

Mobile talent brings different expertise, perspectives, knowledge, and experience into an organization. With a diversity of views, organizations can obtain new ideas that help improve research and development. National diversity can be deemed to represent the mobile talent within an organization, which might increase innovation. Organizations with national diversity are more innovative. Performance is generally based on collaboration between domestic and international talent, which provides the opportunity to capture benefits from the knowledge transfer effect. Most studies on national diversity generally take a headcount of countries on an organizational basis to calculate the National Diversity Index; however, this approach fails to reveal the contribution of knowledge transfer between domestic/international inventor team collaborations. In this study, the authors propose an index, which includes two parts, in which values are assigned based on domestic/international collaboration and international/international collaboration. The index can determine the level of national diversity. The authors further provided a mechanism for visualizing the diversity of inventor teams. An empirical analysis that focuses on the pharmaceutical industry was conducted to test the proposed model. 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

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

In recent years there has been a sharp increase in collaborations among scholars and there are studies on the effects of scientific collaboration on scholars’ performance. This study examines the hypothesis that geographically diverse scientific collaboration is associated with research impact. Here, the approach is differentiated from other studies by: (a) focusing on publications rather than researchers or institutes; (b) considering the geographical diversity of authors of each publication; (c) considering the average number of citations a publication receives per year (time-based normalization of citations) as a surrogate for its impact; and (d) not focusing on a specific country (developed or developing) or region. Analysis of the collected bibliometric data shows that a publication impact is significantly and positively associated with all related geographical collaboration indicators. But publication impact has a stronger association with the numbers of external collaborations at department and institution levels (inter-departmental and inter-institutional collaborations) compared to internal collaborations. Conversely, national collaboration correlates better with impact than international collaboration. 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

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

The tacit nature of knowledge suggests that face-to-face interactions in international academic collaborations are irreplaceable. Yet, such anecdotal evidence has not been adequately examined in the extant literature. Using the difference-in-differences estimation strategy, this paper investigates the causal effect of international nonstop flights on the quantity of high-impact Sino-US joint publications over the period between January 2009 and December 2018. We find that, on average, US-China international nonstop flights boost the production of influential articles aggregated at Chinese cities, with cities with less human capital earning more benefits. We do not find evidence in support of the crowding-out effect indicating this positive effect comes at the expense of domestic and international collaboration opportunities with other countries. These findings remain robust with various specifications. Policy implications for promoting global collaboration through face-to-face communication are discussed in the end. 相似文献

The purpose of this research is to study co-authorship and scientific publications of faculty members at Shahed University, located in Iran, during the period of 2000 to 2008. Scientometrics methods were used to evaluate scientific publications. The rate of co-authorship is high (91.27%) in comparison with single authorship (8.73%). Moreover, there is a great number of scientific collaborations among Shahed University faculty members but international collaboration is low. The article provides insight into co-authorship at Shahed University and provides useful information for researchers who are seeking to learn about the collaboration in scientific works by Iranian researchers at the national and international levels. 相似文献

Greater collaboration generally produces higher category normalised citation impact (CNCI) and more influential science. Citation differences between domestic and international collaborative articles are known, but obscured in analyses of countries’ CNCIs, compromising evaluation insights. Here, we address this problem by deconstructing and distinguishing domestic and international collaboration types to explore differences in article citation rates between collaboration type and countries. Using Web of Science article data covering 2009–2018, we find that individual country citation and CNCI profiles vary significantly between collaboration types (e.g., domestic single institution and international bilateral) and credit counting methods (full and fractional). The ‘boosting’ effect of international collaboration is greatest where total research capacity is smallest, which could mislead interpretation of performance for policy and management purposes. By incorporating collaboration type into the CNCI calculation, we define a new metric labelled Collab-CNCI. This can account for collaboration effects without presuming credit (as fractional counting does). We recommend that analysts should: (1) partition all article datasets so that citation counts can be normalised by collaboration type (Collab-CNCI) to enable improved interpretation for research policy and management; and (2) consider filtering out smaller entities from multinational and multi-institutional analyses where their inclusion is likely to obscure interpretation. 相似文献

Is communication and media research a deeply international field? Are there real and extensive collaborations between various cultures represented on the highest level? In our current research, we analyzed the most recent 620 articles written by 1456 authors and published in 63 SCImago Scopus Q1-ranked journals in communication and media studies (CMS) to reveal the patterns of scientific contribution, the well-connected network of winner-countries, and the sporadic presence of loser or Matthew-countries. We used CATMA and Gephi software to analyze and visualize the distribution patterns behind scientific publications. Our results show that the network of collaboration in CMS is very sparse, most of the scientific publications are written by authors from a very few winner-countries, and the real loser of the field is obviously the CEE region with its lonely, disconnected, and marginalized representatives. 相似文献

ABSTRACTCollaboration with other entities and individuals has long been a standard practice of libraries. Typically, these collaborations seek to reduce redundancies, save money, and support educational and research efforts. However, a new model of collaboration exists that both assists discipline-specific research practices and informs library procedures. This article reviews two collaborations between an assessment librarian and a sociology class. The collaborations are unique because the library is the focus of the collaboration, with sociology students being able to apply classroom learning in a real-world setting. Several suggestions are provided for best practices when endeavoring to use this type of collaboration to inform library practice and engage students in hands-on learning. 相似文献

International collaboration as measured by co-authorship relations on refereed papers grew linearly from 1990 to 2005 in terms of the number of papers, but exponentially in terms of the number of international addresses. This confirms Persson et al.'s [Persson, O., Glänzel, W., & Danell, R. (2004). Inflationary bibliometrics values: The role of scientific collaboration and the need for relative indicators in evaluative studies. Scientometrics, 60(3), 421–432] hypothesis of an inflation in international collaboration. Patterns in international collaboration in science can be considered as network effects, since there is no political institution mediating relationships at that level except for the initiatives of the European Commission. Science at the international level shares features with other complex adaptive systems whose order arises from the interactions of hundreds of agents pursuing self-interested strategies. During the period 2000–2005, the network of global collaborations appears to have reinforced the formation of a core group of fourteen most cooperative countries. This core group can be expected to use knowledge from the global network with great efficiency, since these countries have strong national systems. Countries at the periphery may be disadvantaged by the increased strength of the core. 相似文献

Previous reports stressed on the importance of international collaboration and open access (OA) publishing, as they increase the quality of the research and increase its benefits. In this study, we will assess Jordanian international research collaboration and OA publishing in the past 10 years. We performed a Scopus search for Jordanian publications in the years 2008–2017, where we extracted and calculated the total number of publications, publications in OA journals, publications with international collaborations. Moreover, we assessed the disciplines Jordanians usually publish in. During the 10-year interval, we found a total of 20,359 Jordan-affiliated publications indexed in Scopus. We found a dramatic increase in number of publications with international collaboration from 38% in 2008 reaching 53.3% in 2017, and an increase in OA publications from 7.3% of the total publications in 2008, reaching 18.7% of the total publications in 2017. Total number of Scopus indexed publications from Jordan has increased by 57.9% over the past 10 years. Although international collaboration and OA publications have dramatically increased in recent years, Jordanian researchers should focus more on international collaboration with developed countries and on self-archiving their publications. 相似文献
