    The self-organization of the European Information Society: The case of ?biotechnology?

    Export to Mendeley

    Leyesdorff and Heimeriks select 711 biotechnology papers supplying 787 institutional addresses in Europe, Japan, or the United States in order to determine if this literature can be used to illuminate the interaction between the reorganization of the European science community through transnational collaboration and the transition to so called Mode-2 research with its emphasis on government, university and industry collaboration. The top 10% of title words yields 245 unique types and nine documents that included none of these words were excluded yielding a 778 by 245 document term matrix. Factor analysis of the words provides 99 factors with an eigenvalue above unity and thus reveals no inherent structure and leaves the choice of number of word groupings arbitrary. Discriminant analysis will successfully classify 77.6% of the papers geographically but this level is not statistically significant. The word frequency lists for these geographical sets can be correlated with the forced factor loadings on ten or less dimensions. A three-factor solution which suggests a geographically separate literature, makes the American set more correlated. A four-factor solution which would consider an international factor as well as the three geographical factors, shows us American and European correlations at almost equal strength to different factors. The European set is correctly classified by discriminant analysis in 86.5% of cases. Its disaggregation shows differences and thus seems to be a part of a global phenomenon not national interactions. The European vocabulary factor disappears after disaggeration..

    Description

    Title : The self-organization of the European Information Society: The case of ?biotechnology?
    Author(s) : Loet Leydesdorff, Gaston Heimeriks
    Abstract : Leyesdorff and Heimeriks select 711 biotechnology papers supplying 787 institutional addresses in Europe, Japan, or the United States in order to determine if this literature can be used to illuminate the interaction between the reorganization of the European science community through transnational collaboration and the transition to so called Mode-2 research with its emphasis on government, university and industry collaboration. The top 10% of title words yields 245 unique types and nine documents that included none of these words were excluded yielding a 778 by 245 document term matrix. Factor analysis of the words provides 99 factors with an eigenvalue above unity and thus reveals no inherent structure and leaves the choice of number of word groupings arbitrary. Discriminant analysis will successfully classify 77.6% of the papers geographically but this level is not statistically significant. The word frequency lists for these geographical sets can be correlated with the forced factor loadings on ten or less dimensions. A three-factor solution which suggests a geographically separate literature, makes the American set more correlated. A four-factor solution which would consider an international factor as well as the three geographical factors, shows us American and European correlations at almost equal strength to different factors. The European set is correctly classified by discriminant analysis in 86.5% of cases. Its disaggregation shows differences and thus seems to be a part of a global phenomenon not national interactions. The European vocabulary factor disappears after disaggeration..
