This study introduces a hybrid approach (i.e., a social network analysis technique and triple helix indicators) to study certain aspects of the e-government (EG) domain that would otherwise remain hidden when using conventional analytic tools. Particularly, we provide network analysis of the EG research domain by focusing on the network collaboration between regions, nations and institutions. We collected and analyzed 1091 scholarly papers which were classified as being about “e-government” by the Web of Science database. The results indicate that hybrid method can be used to understand certain network-level structures and patterns in the EG domain which are beyond the scope of the predominantly-used systematic literature review (SLR) method. Particularly, the hybrid method is useful in understanding collaboration patterns between countries, institutions and regions in the EG domain, identifying key players by studying their network properties (i.e., degree centralities); and in understanding the pattern of relations among universities, industries, and government. The implications of these results in terms of research and practice, and study limitations are discussed. 相似文献

Extant studies suggest that the proximity between the researchers and their structural positioning in the collaboration network may influence productivity and performance in collaboration research. In this paper, we analyze the co-authorship networks of the three countries, viz. the USA, China, and India, constructed in consecutive non-overlapping 5-year long time windows from bibliometric data of research papers published in the past decade in the rapidly evolving area of Artificial Intelligence and Machine Learning (AI&ML). Our analysis relies on the observations ensued from a comparison of the statistical properties of the evolving networks. We consider macro-level network properties which describe the global characteristics, such as degree distribution, assortativity, and large-scale cohesion etc., as well as micro-level properties associated with the actors who have assumed central positions, defining a core in the network assembly with respect to closeness centrality measure. For the analysis of the core actors, who are well connected with a large number of other actors, we consider share of their affiliations with domestic institutes. We find dominant representation of domestic affiliations of the core actors for high productivity cases, such as China in the second time window and the USA in the first and second both. Our study, therefore, suggests that the domestic affiliation of the core actors, who could access network resources more efficiently than other actors, influences and catalyzes the collaborative research. 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

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 paper examines the structural patterns of networks of internationally co-authored SCI papers in the domain of research driven by big data and provides an empirical analysis of semantic patterns of paper titles. The results based on data collected from the DVD version of the 2011 SCI database identify the U.S. as the most central country, followed by the U.K., Germany, France, Italy, Australia, the Netherlands, Canada, and Spain, in that order. However, some countries (e.g., Portugal) with low degree centrality occupied relatively central positions in terms of betweenness centrality. The results of the semantic network analysis suggest that internationally co-authored papers tend to focus on primary technologies, particularly in terms of programming and related database issues. The results show that a combination of words and locations can provide a richer representation of an emerging field of science than the sum of the two separate representations. 相似文献

Increasing political and financial support for scientific research in the Middle East requires academic and research communities in the region to demonstrate the visibility and impact of their scientific output. However, for countries with smaller scientific communities or lack of detailed information on their scientific production, the use of common metrics of scientific impact (e.g., number of papers, impact factor, h-index, etc.) may fail to reveal their true ability to produce high quality research, and thus guarantee the wanted societal support. In such cases, identifying and highlighting outstanding papers produced by national institutions or scientists may be another way to demonstrate scientific capacity and impact. In this context, this work aims to provide an overview of champion works (papers that have received over 1,000 citations) produced by Middle East countries. This analysis focuses on science, medicine, and technology papers featured in the Science Citation Index Expanded of Web of Science. The authors identified 213 champion works authored by Middle East scientists published since the 1970s. Israel is currently the leading nation in the Middle East in terms of published champion works, but at least one such work was identified for the majority of countries in the region. Middle East champion works were published on a diverse range of subject categories and often featured in the top journals worldwide (e.g., Science, Nature, etc.). The top institutions in the Middle East authoring champion works and their leading collaborating countries worldwide are listed, and the role of international scientific collaborations in achieving these highly cited papers is highlighted. 相似文献

Modeling a century of citation distributions 总被引：1，自引：1，他引：0
The prevalence of uncited papers or of highly cited papers, with respect to the bulk of publications, provides important clues as to the dynamics of scientific research. Using 25 million papers and 600 million references from the Web of Science over the 1900–2006 period, this paper proposes a simple model based on a random selection process to explain the “uncitedness” phenomenon and its decline over the years. We show that the proportion of cited papers is a function of (1) the number of articles available (the competing papers), (2) the number of citing papers and (3) the number of references they contain. Using uncitedness as a departure point, we demonstrate the utility of the stretched-exponential function and a form of the Tsallis q-exponential function to fit complete citation distributions over the 20th century. As opposed to simple power-law fits, for instance, both these approaches are shown to be empirically well-grounded and robust enough to better understand citation dynamics at the aggregate level. On the basis of these models, we provide quantitative evidence and provisional explanations for an important shift in citation practices around 1960. We also propose a revision of the “citation classic” category as a set of articles which is clearly distinguishable from the rest of the field. 相似文献

The relative performance of science and technology (S&T) in the USA and PRC was compared in terms of quantity and quality, as reflected in their technical literatures. Three databases (Science Citation Index (SCI), INSPEC, Ei Compendex) were selected for the quantity comparison, and citation analysis in the SCI was used for the quality comparison. Thirty technology and research areas were compared for quantity production, and are presented in this paper. These 30 areas were selected based on our previous assessment of PRC S&T output, and represented areas of emphasis by the PRC in physical, environmental, engineering, and life sciences.In almost all technical areas, the USA had the quantity (number of papers) lead (for the period 2002–2007) based on the SCI results, although the PRC has made dramatic strides to overtake the USA. In most of the technical areas, by 2007 PRC had attained parity with, or exceeded, the S&T literature production of the USA in the INSPEC database. The major exceptions were the biomedical field and some aspects of environmental science, where the USA still had a large lead. For most technical areas, by 2007 the PRC had even higher relative S&T literature production, based on the Ei Compendex, compared to the INSPEC results. Moreover, the USA production appears to have peaked (in the Ei Compendex) in the 2005 time frame, despite increasing amounts of funding for S&T research. The PRC challenge in non-biomedical research and technology sectors becomes apparent in those databases that do not contain substantial biomedical research papers, and therefore remove a substantial intrinsic USA advantage.For quality computations, the publication and citation results were normalized to discrete slices of time, and are presented for nanotechnology only (for the period 1998–2003). While the USA held a commanding lead in quality over the PRC (and the other major nanotechnology producer nations as well) during the past decade, the PRC has increased the quality of its publications monotonically, and now appears to be competitive with France, Italy, Japan, and Australia, using the quality metric in this paper. 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

Macro-level indicators of the relations between research funding and research output 总被引：3，自引：0，他引：3
In response to the call for a science of science policy, we discuss the contribution of indicators at the macro-level of nations from a scientometric perspective. In addition to global trends such as the rise of China, one can relate percentages of world share of publications to government expenditure in academic research. The marginal costs of improving one's share are increasing over time. Countries differ considerably in terms of the efficiency of turning (financial) input into bibliometrically measurable output. Both funding schemes and disciplinary portfolios differ among countries. A price per paper can nevertheless be estimated. The percentages of GDP spent on academic research in different nations are significantly correlated to historical contingencies such as the percentage of researchers in the population. The institutional dynamics make strategic objectives such as the Lisbon objective of the EU – that is, spending 3% of GDP for R&D in 2010 – unrealistic. 相似文献

The Bureau of the Census initiated the American Community Survey (ACS) in 2005. It will revolutionize the use of census data by providing annual updates to statistics that in the past were collected only every 10 years. Statistics will be published for areas of 65,000 people or more every year. The Bureau of the Census will distribute data for areas of between 20,000 and 64,999 in "3-year period averages." The first 3 year average will appear in 2008 covering 2005–2007. Subsequent data will be issued annually for the following three year periods. (e.g., 2006–2008, 2007–2009) Statistics for areas smaller than 19,999 will be published in 5-year period averages, the first to be published in 2010 covering 2005–2009. Subsequent data to be issued annually will cover 2006–2010, 2007–20011, … This paper provides background information about ACS, similarities and differences between it and the decennial census, the interpretation of statistics based upon period averages, relationships among ACS and other Bureau of the Census Surveys, and the expected future of the survey. 相似文献

The study intends to examine the publication patterns of International Information and Library Review from 2004 to 2013 and to predict the impact and influence of this established journal in the field of library and information science over the last decade. The study finds that International Information and Library Review has published the majority of papers in single authorship mode followed by in two-authorship mode while, contributions in three authorship and more than three-authorship mode are found less. The degree of collaboration in International Information and Library Review publications is found to be 0.45, indicating less intensity of collaborative trend of research. The study reveals that the University of Pittsburgh of the United States is the top performer with 12 authors followed by University of Wisconsin Milwaukee of the United States (10 authors), Universiteit van Pretoria of South Africa and University of the Punjab Lahore of Pakistan (7 authors each). In regard to geographical distribution of contributions, the United States is represented by contributions from 63 authors followed by India with 61 authors. Interestingly, 22 countries like, Argentina, Bhutan, Brazil, Cuba, and others have contributed one paper each. The study further reveals that Britz, J. J. of South Africa is identified as the most prolific author with a significant contribution of five papers followed by Bagheri, M. of Iran, Megnigbeto, E. of Benin, and Tuamsuk, K. of Thailand (four papers each). Moreover, the 2013 impact factor of International Information and Library Review based on records of Scopus citations is 0.588 and immediacy index is 0.09. 相似文献

This study examines global collaborative creativity through patentometrics and social network analysis. Because patents are a direct output of innovative activities, cross-border patents are used to analyze the trend of global collaborative creativity. The results show linear growth of cross-border patents, while numerous inventors have grown exponentially for collaborative creativity. The number of inventors for global collaborative creativity trends have increased more rapidly than the number of patents. The network for global collaborative creativity is denser and shows a growing trend over a five-year interval. Both observed and cosine-normalized numbers of k-cores in global collaborative creativity show a growing trend, while the cosine-normalized k-cores increase slowly compared to the observed one. Similarly, the social network analysis confirms a growing network of global collaborative creativity, which is dense despite its small degree of growth. This study also found that high values of “betweenness” tend to spread from core countries to periphery countries. Collaborative creativity has globalized but remains concentrated in core countries such as the U.S., the UK, France, Germany, and Canada. 相似文献
