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

［目的/意义］ 科学合作的多样性是科学计量学领域"团队科学"研究主题中的一个新兴研究点,与以往线性视角下的合作特征不同,它是一种多维度、系统性视角下的结构性特征。对科学合作多样性的研究与梳理有助于理解科学合作的内在结构、本质和价值。［方法/过程］ 对科学计量学领域的合作多样性相关研究进行评述:首先系统梳理和界定了科学合作多样性的类型和概念维度,基于作者属性将其定义为四大类共10种不同的合作多样性;其次从概念内涵、测度方法、效用分析3个维度,分别对各类型合作多样性进行研究评述;最后总结了现有研究不足并对未来研究做出展望。［结果/结论］ 研究发现,现有文献更加偏重基于文献计量特征属性的合作多样性研究,而对个体属性与专业属性的合作多样性的研究较少,并且大多体现多样性概念框架的部分内涵;测度方法也以传统方法为主,使用新型多样性测度方法(考虑了相似性维度)较少;效用研究则以引文影响力的单一类型效用为主。未来研究需关注非文献计量属性的合作多样性类型,以及体现多样性概念完整内涵,探索包含相似性维度的多样性测度方法,在效用研究中需扩展质量层面的多类型效用研究,尤其需加强背后的成因分析。  相似文献

This article reports on quantitative data collected in a mixed methods study of teacher and librarian collaboration. This practice is discussed extensively in the literature on school librarianship as an instructional strategy that positively affects student academic achievement. However, while there is much anecdotal evidence regarding successful teacher and librarian collaboration, there is little hard research that defines specific practices that lead to successful collaborations. This study provides empirical data on teacher and librarian collaboration which helps us understand the nature of collaboration and the extent to which theory and practice are integrated. Two surveys based on proposed theoretical models of teacher and librarian collaboration were used for this study. The first survey was based on Loertscger's Taxonomy. The second survey was based on a new proposed model of teacher and librarian collaboration (TLC Model) which builds on the taxonomy and expands our understanding of teacher and librarian collaboration. Participants in the study included teachers, librarians and principals from kindergarten through middle school. An exploratory factor analysis (EFA) was carried out on both surveys to identify underlying structures of teacher and librarian collaboration. Three factors emerged from the data identifying a range of underlying structures: integrated instruction, library and librarian as resource, and traditional role for teacher and librarian. Further research on the TLC Model with a larger number of participants and survey items is needed to examine the stability of the factor structures and to further refine the new measure.  相似文献

The aim of this paper is to establish the similarities and differences between the way of collaboration and the production of researchers when dealing with publications or with the development of projects and whether the collaboration patterns change across disciplines.We have studied the networks of researchers formed through the collaborations in papers or in projects in a research institution (the University of Zaragoza) and we have analyzed a series of individual and global magnitudes. As a general result, we have observed that the laws governing the individual productivity are similar for the cases of publications and projects but, however, the behavior is different when analyzing more complex magnitudes such as the collaborations or other structural variables. We consider also the subnetworks defined by the researchers of the different disciplines and characterize their topologies and compare the corresponding collaboration patterns.Because of the general approach, we expect most of the conclusions to be applicable to other universities or research centers.  相似文献

Collaboration usually has a positive effect on researchers’ productivity: researchers have become increasingly collaborative, according to recent studies. Numerous studies have focused on enhancing research collaboration by recommendation technology and measuring the influence of researchers. However, few studies have investigated the effect of collaboration on the position of a researcher in the research social network. In this paper, we explore the relationships between collaboration and influence by social analytical methods, which are pertinent to analyzing the network structure and individual traits. We evaluate three aspects of the researchers’ influence: friendship paradox validation, social circle, and structure of a researcher's ego network. Furthermore, the ”six degrees of Bacon number” theory, generalized friendship paradox, and triadic closure theory are introduced to support our analysis. Experimental results show that collaboration can help researchers increase their influence to some extent.  相似文献

Scientific collaboration is a significant behavior in knowledge creation and idea exchange. To tackle large and complex research questions, a trend of team formation has been observed in recent decades. In this study, we focus on recognizing collaborative teams and exploring inner patterns using scholarly big graph data. We propose a collaborative team recognition (CORE) model with a ”core + extension” team structure to recognize collaborative teams in large academic networks. In CORE, we combine an effective evaluation index called the collaboration intensity index with a series of structural features to recognize collaborative teams in which members are in close collaboration relationships. Then, CORE is used to guide the core team members to their extension members. CORE can also serve as the foundation for team-based research. The simulation results indicate that CORE reveals inner patterns of scientific collaboration: senior scholars have broad collaborative relationships and fixed collaboration patterns, which are the underlying mechanisms of team assembly. The experimental results demonstrate that CORE is promising compared with state-of-the-art methods.  相似文献

Academic collaboration prediction is considered to be an important way to help scholars expand their research horizons and explore a vast and suitable range of partners. However, existing studies mainly rely on historical collaborations for future predictions, which has limitations in digging into credible collaboration possibilities in a wide range of cross-disciplinary contexts. In view of this, this study tries to combine three typical citation relationships (including direct citation, co-citation, and coupling) to predict prospective collaborations based on citation information that reflects the characteristics of scholars’ knowledge structure and research habits, which is supposed to provide supplement and extension for traditional implementation. To this end, we construct all-author tripartite citation networks based on the bibliographic data in the field of gene editing, and apply the Node2vec and Multi-node2vec algorithms to predict collaborations between authors in both single and multiple layers. According to compare with that of link prediction indicators (including CN, AA, PA and RA, etc.) commonly used for traditional collaboration networks, it is found that the prediction results in the multilayer all-author tripartite citation network should be relatively more accurate. The results will be helpful for scholars in the field of gene editing to explore potential collaborators with an implicit research connection.  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

Scientific collaboration is a distinct iteration of information creation as a process. It aims to form willful relationships between scientists to achieve the shared objective of new information creation with the end goal of knowledge production. Findings of an exploratory study investigating barriers that hinder effective scientific collaboration and strategies to cope with these obstacles are reported. A qualitative and interpretive methodology is leveraged to analyze data collected from 14 in-depth interviews with researchers who work in a cross-disciplinary scientific research center. The results indicate that domain disparity and motivation and engagement are the strongest hindrances to effective collaboration. Researchers adopt active and constant learning as an approach to mitigate barriers, lower affective distress, and improve collaboration processes. Malleable boundary objects can facilitate collaboration by adjusting to research aims but may also contort projects, manifesting as a barrier to new information creation.  相似文献

Digitised versions of archival fonds with micro or regional significance daily join mass digitisation projects of books and documents in the global digital space. For historians, the exponential expansion of searchable digital archival material has required the revision of traditional research methods. The digital age has also shifted disciplinary boundaries such as the distinction between historian and archivist. This article concerns a micro digitisation involving collaboration between historian and archivist, not in archive access as is usually the case, but in archive creation. The experience of this collaboration is generalisable to other micro-scale uploads of scanned material enabled by digital technologies. This article is a case study of this experience. It uses autoethnography to explore the practicalities and ethical processes of decision-making to create a new digital archive of wine history during the pilot stage of an Australian Research Council Industry Linkage Grant. The decision-making process that transformed a historian as traditional archive end-user to archive creator highlights the challenges for both professions in the decision to digitise, the implications for expenditure of public funds and questions of digitisation and environmental sustainability.  相似文献

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

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

Previous research has shown that clarity of roles and responsibilities (CRR) influences the performance of individual organizations as well as inter-organizational efforts. In the context of cross-boundary information sharing (CBIS), CRR has been found to enable other important determinants of success, such as building trust among members, increasing their willingness to participate, and mitigating some of their concerns about security, among others. However, few studies have attempted to understand the determinants of CRR in government CBIS initiatives. Sayogo, Gil-Garcia, and Cronemberger's (2016) analysis of results of a national survey identified three significant determinants of CRR in CBIS, (1) the extent participants use boundary objects, (2) participant skills in terms of collaboration, coordination, and communication, and (3) the diversity of the participating organizations and their goals. Seeking to expand on their findings in terms of new understanding about the influence of significant determinants of CRR in CBIS, this study draws on findings from eight U.S. state and local government public health and criminal justice CBIS cases. This study contributes to existing knowledge about CBIS in the public sector by characterizing the determinants and providing new understanding of the nature of the influence of the determinants of CRR on CBIS. In particular, it shows how the extent of boundary object use, collaboration, and the diversity of participants affect CBIS initiatives in different contexts. In practical terms, creating new understanding of the determinants of CRR has value for public managers and their leadership as they must increasingly collaborate and share information across the boundaries of organizations in the process solving increasingly complex public problems.  相似文献

Studies of social networks highlight the importance of network structure or structural properties of a given network and its impact on performance outcome. One of the important properties of this network structure is referred to as social capital, which is the network of contacts and the associated values attached to these networks of contacts. This study provides empirical evidence of the influence of social capital and performance within the context of academic collaboration (coauthorship) and suggests that the collaborative process involves social capital embedded within relationships and network structures among direct coauthors. Association between scholars' social capital and their citation-based performance measures is examined. To overcome the limitations of traditional social network metrics for measuring the influence of scholars' social capital within coauthorship networks, the traditional social network metrics is extended by proposing two new measures, of which one is non-weighted (the power–diversity index) and the other (power–tie–diversity index) is weighted by the number of collaboration instances. The Spearman's correlation rank test is used to examine the association between scholars' social capital measures and their citation-based performance. Results suggest that research performance of authors is positively correlated with their social capital measures. The power–diversity index and power–tie–diversity index serve as indicators of power and influence of an individual's ability to control communication and information.  相似文献

The media are normatively expected to play significant roles in conflictual discussions within national and international communities. As previous research shows, digital platforms make scholars rethink these roles based on media behavior in online communicative environments as well as on the structural limitations of the platforms. At the same time, traditional dichotomies between information dissemination and opinion formation roles, although seemingly universal, also vary across cultures. We look at four recent conflicts of comparable nature in the United States, Germany, France, and Russia to assess the roles that legacy media have performed in the respective ad hoc discussions on Twitter. Our approach differs from previous studies, as we combine content analysis of tweets by the media and journalists with the resulting positions of the media in the discussion graphs. Our findings show that, despite the overall trend of the “elite” and regional media sticking to information dissemination, online-only media and individual journalists vary greatly in their normative strategies, and this is true across countries. We also show that combining performance in content and social network analysis may allow for reconceptualization of media roles in a more flexible way.  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
