This study investigates how business research scholars’ internationalization strategies influence their research performance and how this relationship is moderated by the availability of different knowledge-based resources. The authors analyze citations to journal articles authored by business research scholars with German affiliations and examine how the number of citations is determined by international collaborations and a researcher's knowledge resources in terms of language skills, research experience, and foreign market knowledge. The results demonstrate that the augmentation of complementary knowledge resources (i.e., when researchers lack language skills and foreign market knowledge) positively influences the performance of a collaboration-based internationalization strategy (i.e., collaborations with international researchers). The collaboration-based strategy also improves performance for less experienced researchers, but this advantage diminishes with increasing research experience. The findings provide further insights into drivers of scholars’ research performance and have practical implications for science policy.  相似文献

Co-authorship networks and research impact: A social capital perspective   总被引:1,自引:0,他引:1  
The impact of research work is related to a scholar's reputation and future promotions. Greater research impact not only inspires scholars to continue their research, but also increases the possibility of a larger research budget from sponsors. Given the importance of research impact, this study proposes that utilizing social capital embedded in a social structure is an effective way to achieve more research impact. The contribution of this study is to define six indicators of social capital (degree centrality, closeness centrality, betweenness centrality, prolific co-author count, team exploration, and publishing tenure) and investigate how these indicators interact and affect citations for publications. A total of 137 Information Systems scholars from the Social Science Citation Index database were selected to test the hypothesized relationships. The results show that betweenness centrality plays the most important role in taking advantage of non-redundant resources in a co-authorship network, thereby significantly affecting citations for publications. In addition, we found that prolific co-author count, team exploration, and publishing tenure all have indirect effects on citation count. Specifically, co-authoring with prolific scholars helps researchers develop centralities and, in turn, generate higher numbers of citations. Researchers with longer publishing tenure tend to have higher degree centrality. When they collaborate more with different scholars, they achieve more closeness and betweenness centralities, but risk being distrusted by prolific scholars and losing chances to co-author with them. Finally, implications of findings and recommendations for future research are discussed.  相似文献

New indicators for gender studies in Web networks   总被引:2,自引:1,他引:2  
New indicators for gender studies are introduced using the multi-authored publications of a set of 64 members of the COLLNET network. Considering the sample of 223 papers and their visibility on the Web, analyses were performed on the sets comprised of publications on the one hand and the authors (social network analysis) on the other.The indicators developed include: Gender co-operation; Web visibility rates and Gender centrality in networks.The co-operation among COLLNET members results in a publication set with a different pattern to other gender studies in science, which show low contribution rates of women in collaboration activities. In the sample the collaboration patterns of female COLLNET members are almost the same as their male counterparts. However, when considering only the arrangement of gender in the by-line of publications, this is in favour of men.Regarding average Web visibility rates, there are no differences dependent upon the arrangement of gender in publications with both male and female co-authors. However, the results also show strong gender differences in favour of publications with only male co-authors.The centrality of female actors in the networks is correlated with the central positions of women in the International Society for Scientometrics and Informetrics (ISSI), where they are leading either as presidents or organisers of its international conferences.It may well be that, with webometric methods and new indicators for gender studies, there is a real continuation of gender equality in COLLNET over time.  相似文献

As globalization has expedited mobility of faculty across nations, faculty hiring is taking place at an international level. Institutions and governments often perceive hiring faculty who were trained in different countries as a strategy for reaching the status of world-class universities. The major assumption behind this hiring strategy is that faculty who are educated in prestigious universities in foreign countries will bring cutting edge knowledge and networks that will lead to future research collaborations. Yet, a dearth of research empirically investigated the assumption that institutions that train future foreign faculty and those that hire faculty with foreign degrees will have greater presence in the international networks of research collaboration. Filling this hole, this study examines this assumption from an international perspective, using the case of industrial engineering departments at selective research universities in Chile and Korea. Based on the unique data that document faculty hiring (degree attainment institutions) and research collaboration (co-authorship), and institutional prestige (global ranking positions), we analyzed the relationship between faculty hiring network and research collaboration network, as well as their association with institutional prestige. The results provide strong evidence of the positive relationships between doctoral training and future research collaboration, and the strong presence of institutions with global prestige. These relationships result in homophilic networks that suggest a concern about a reduced diversity in theoretical perspective and research methods within the disciplinary field.  相似文献

This study examines the longitudinal trend of systemness in networked research relations in South Korea using a triple helix (TH) indicator of university-industry-government (UIG) relations. The data were harvested from the Science Citation Index (SCI) and its counterparts in the social sciences (SSCI) and the arts and humanities (A&HCI). The total number of Korean SCI publications has grown rapidly since 1965. However, the TH indicator shows that the network dynamics have varied considerably according to the research policies of the national government. The collaboration patterns, as measured by co-authorship relations in the SCI noticeably increased, with some variation, from the mid-1970s to the mid-1990s. However, inter-institutional collaboration in the first decade of the 21st century was negatively influenced by the new national science and technology (S&T) research policies that evaluated domestic scientists and research groups based on their international publication numbers rather than on the level of cooperation among academic, private, and public domains. The results reveal that Korea has failed to boost its national research capacity by neglecting the network effects in science, technology, and industry.  相似文献

Knowledge production and scientific research have become increasingly more collaborative and international, particularly in pharmaceuticals. We analyze this tendency in general and tie formation in international research networks on the country level in particular. Based on a unique dataset of scientific publications related to pharmaceutical research and applying social network analysis, we find that both the number of countries and their connectivity increase in almost all disease group specific networks. The cores of the networks consist of high income OECD countries and remain rather stable over time. Using network regression techniques to analyze the network dynamics our results indicate that accumulative advantages based on connectedness and multi-connectivity are positively related to changes in the countries’ collaboration intensity whereas various indicators on similarity between countries do not allow for unambiguous conclusions.  相似文献

International research collaboration (IRC) has been increasingly important as an emerging area of innovation studies. This study reviews the intellectual base, main research trajectories and intellectual communities of the IRC research domain over the period 1957–2015. It integrates qualitative review and three quantitative analyses including co-citation network analysis, main path analysis and bibliographic coupling analysis. The results show that the IRC research has gone through three phases, namely, “emergence” (1957–1991), “fermentation” (1992–2005) and “take-off” (2006–2015) phases. The co-citation network analysis confirms that the IRC research field has been developed under the influence of two pioneering studies related to bibliometrics research. The main research trajectories in IRC studies over the three development phases and over the whole period are identified based on the main path analysis, which shows that co-authorship analysis is the main research method in IRC studies. A bibliographic coupling analysis suggests that the whole IRC research domain can be classified into five distinct intellectual areas: drivers of IRC, IRC patterns, IRC effects, IRC networks and IRC measurement. Seven topics for future research are also identified.  相似文献
