    The Geography of Scientific Collaboration

    Get PDF
    Science is increasingly defined by multidimensional collaborative networks. Despite the unprecedented growth of scientific collaboration around the globe – the collaborative turn – geography still matters for the cognitive enterprise. This book explores how geography conditions scientific collaboration and how collaboration affects the spatiality of science. This book offers a complex analysis of the spatial aspects of scientific collaboration, addressing the topic at a number of levels: individual, organizational, urban, regional, national, and international. Spatial patterns of scientific collaboration are analysed along with their determinants and consequences. By combining a vast array of approaches, concepts, and methodologies, the volume offers a comprehensive theoretical framework for the geography of scientific collaboration. The examples of scientific collaboration policy discussed in the book are taken from the European Union, the United States, and China. Through a number of case studies the authors analyse the background, development and evaluation of these policies. This book will be of interest to researchers in diverse disciplines such as regional studies, scientometrics, R&D policy, socio-economic geography and network analysis. It will also be of interest to policymakers, and to managers of research organisations

    Spatial Structure of National and International Scientific Collaboration in the Brazilian Cerrado Research

    The number of authors in papers has increased over the years, indicating collaborative trends in Science and Technology. Besides, scientific collaboration is structured at different spatial scales, for example, within or between institutions in the same country or among countries. Here, we evaluate the scientific collaboration patterns at national and international levels in the Cerrado research. We searched all papers about the Cerrado published between 1945 and 2017 in the Web of Science database. We performed network analyses using pairwise distance matrices to create national and international collaboration networks. We also used spatial correlograms to test the effect of geographic distance on scientific collaboration. The number of papers increased over the years (rs = 0.96), where papers with 3-5 authors had the highest growth rate (rs = 0.96). Moreover, authors from geographically closer institutions tend to collaborate more at the national level, while we found no geographic effect on international collaboration. These results show that Brazilian scientists studying the Cerrado have collaborated more over the years regardless of distance, although locally, scientists are still more likely to work with scientists of close institutions within the biome. This collaboration tendency may be associated with the need in science to deal with more complex and multidisciplinary issues, where collaborative studies promote a greater scientific and social impact.O número de autores em artigos tem aumentado ao longo dos anos, indicando tendências colaborativas em Ciência e Tecnologia. Além disso, a colaboração científica é estruturada em diferentes escalas espaciais, por exemplo, dentre ou entre instituições no mesmo país ou entre países. Aqui nós avaliamos os padrões da colaboração científica em nível nacional e internacional na pesquisa no Cerrado. Nós buscamos todos os artigos sobre o Cerrado publicados entre 1945 e 2017 no banco de dados Web of Science. As análises de rede foram realizadas usando matrizes de distância par-a-par para criar a rede de colaboração nacional e internacional. Correlogramas espaciais também foram utilizados para testar o efeito da distância geográfica sobre as redes de colaboração. O número de artigos aumentou ao longo dos anos (rs = 0.96), onde artigos com 3-5 autores tiveram a maior taxa de crescimento (rs = 0.96). Além disso, autores de instituições geograficamente mais próximas tendem a colaborar mais em nível nacional, enquanto nenhum efeito geográfico sobre a colaboração internacional. Esses resultados mostram que cientistas brasileiros estudando o Cerrado tem colaborado mais ao longo do tempo independente da distância, embora localmente, cientistas ainda tendem a trabalhar junto de cientistas de instituições mais próximas dentro do bioma. Essa tendência colaborativa pode estar associada com a necessidade da ciência em lidar com problemas mais complexo e multidisciplinares, ao qual estudos em colaboração promovem um maior impacto cientifico e social

    Collaboration in sensor network research: an in-depth longitudinal analysis of assortative mixing patterns

    Get PDF
    Many investigations of scientific collaboration are based on statistical analyses of large networks constructed from bibliographic repositories. These investigations often rely on a wealth of bibliographic data, but very little or no other information about the individuals in the network, and thus, fail to illustrate the broader social and academic landscape in which collaboration takes place. In this article, we perform an in-depth longitudinal analysis of a relatively small network of scientific collaboration (N = 291) constructed from the bibliographic record of a research center involved in the development and application of sensor network and wireless technologies. We perform a preliminary analysis of selected structural properties of the network, computing its range, configuration and topology. We then support our preliminary statistical analysis with an in-depth temporal investigation of the assortative mixing of selected node characteristics, unveiling the researchers' propensity to collaborate preferentially with others with a similar academic profile. Our qualitative analysis of mixing patterns offers clues as to the nature of the scientific community being modeled in relation to its organizational, disciplinary, institutional, and international arrangements of collaboration.Comment: Scientometrics (In press

    A New Approach to Analyzing Patterns of Collaboration in Co-authorship Networks - Mesoscopic Analysis and Interpretation

    Full text link
    This paper focuses on methods to study patterns of collaboration in co-authorship networks at the mesoscopic level. We combine qualitative methods (participant interviews) with quantitative methods (network analysis) and demonstrate the application and value of our approach in a case study comparing three research fields in chemistry. A mesoscopic level of analysis means that in addition to the basic analytic unit of the individual researcher as node in a co-author network, we base our analysis on the observed modular structure of co-author networks. We interpret the clustering of authors into groups as bibliometric footprints of the basic collective units of knowledge production in a research specialty. We find two types of coauthor-linking patterns between author clusters that we interpret as representing two different forms of cooperative behavior, transfer-type connections due to career migrations or one-off services rendered, and stronger, dedicated inter-group collaboration. Hence the generic coauthor network of a research specialty can be understood as the overlay of two distinct types of cooperative networks between groups of authors publishing in a research specialty. We show how our analytic approach exposes field specific differences in the social organization of research.Comment: An earlier version of the paper was presented at ISSI 2009, 14-17 July, Rio de Janeiro, Brazil. Revised version accepted on 2 April 2010 for publication in Scientometrics. Removed part on node-role connectivity profile analysis after finding error in calculation and deciding to postpone analysis

    International Collaboration in Science and the Formation of a Core Group

    Full text link
    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 (2004) 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. 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

    International collaboration clusters in Africa

    Full text link
    Recent discussion about the increase in international research collaboration suggests a comprehensive global network centred around a group of core countries and driven by generic socio-economic factors where the global system influences all national and institutional outcomes. In counterpoint, we demonstrate that the collaboration pattern for countries in Africa is far from universal. Instead, it exhibits layers of internal clusters and external links that are explained not by monotypic global influences but by regional geography and, perhaps even more strongly, by history, culture and language. Analysis of these bottom-up, subjective, human factors is required in order to provide the fuller explanation useful for policy and management purposes.Comment: 12 pp, 5 Figs including map links to viewe

    The Local Emergence and Global Diffusion of Research Technologies: An Exploration of Patterns of Network Formation

    Full text link
    Grasping the fruits of "emerging technologies" is an objective of many government priority programs in a knowledge-based and globalizing economy. We use the publication records (in the Science Citation Index) of two emerging technologies to study the mechanisms of diffusion in the case of two innovation trajectories: small interference RNA (siRNA) and nano-crystalline solar cells (NCSC). Methods for analyzing and visualizing geographical and cognitive diffusion are specified as indicators of different dynamics. Geographical diffusion is illustrated with overlays to Google Maps; cognitive diffusion is mapped using an overlay to a map based on the ISI Subject Categories. The evolving geographical networks show both preferential attachment and small-world characteristics. The strength of preferential attachment decreases over time, while the network evolves into an oligopolistic control structure with small-world characteristics. The transition from disciplinary-oriented ("mode-1") to transfer-oriented ("mode-2") research is suggested as the crucial difference in explaining the different rates of diffusion between siRNA and NCSC
