Global Maps of Science based on the new Web-of-Science Categories

In August 2011, Thomson Reuters launched version 5 of the Science and Social Science Citation Index in the Web of Science (WoS). Among other things, the 222 ISI Subject Categories (SCs) for these two databases in version 4 of WoS were renamed and extended to 225 WoS Categories (WCs). A new set of 151 Subject Categories (SCs) was added, but at a higher level of aggregation. Since we previously used the ISI SCs as the baseline for a global map in Pajek (Rafols et al., 2010) and brought this facility online (at http://www.leydesdorff.net/overlaytoolkit), we recalibrated this map for the new WC categories using the Journal Citation Reports 2010. In the new installation, the base maps can also be made using VOSviewer (Van Eck & Waltman, 2010).Comment: Scientometrics, in pres

Diversity and Polarization of Research Performance: Evidence from Hungary

Measuring the intellectual diversity encoded in publication records as a proxy to the degree of interdisciplinarity has recently received considerable attention in the science mapping community. The present paper draws upon the use of the Stirling index as a diversity measure applied to a network model (customized science map) of research profiles, proposed by several authors. A modified version of the index is used and compared with the previous versions on a sample data set in order to rank top Hungarian research organizations (HROs) according to their research performance diversity. Results, unexpected in several respects, show that the modified index is a candidate for measuring the degree of polarization of a research profile. The study also points towards a possible typology of publication portfolios that instantiate different types of diversity

Global dimension in engineering education : promoting global learning in Spanish universities

La iniciativa ‘Dimensión Global en los Estudios Tecnológicos’ (GDEE) es una red que pretende mejorar el conocimiento, la comprensión crítica y los valores actitudinales de los estudiantes y de los postgraduados de las universidades científicotecnológicas en relación al Desarrollo Humano Sostenible (DHS). El objetivo es promover la integración del DHS como tema transversal en el currículo, mediante la mejora de las competencias de los profesores y a través de su participación y la de los estudiantes en iniciativas relacionadas con el DHS. La iniciativa empezó como un proyecto de colaboración entre un consorcio de universidades europeas y ONGs financiado por EuropeAid. Esta contribución presenta y discute la experiencia europea GDEE, profundizando las barreras y oportunidades encontradas, centrándose especialmente en la replicabilidad potencial de esta iniciativa. Estos resultados se complementan con la caracterización y el análisis comparativo del perfil académico de una comunidad de profesores implicados en actividades promovidas por GDEE.Peer ReviewedPostprint (author's final draft

Knowledge Integration and Diffusion: Measures and Mapping of Diversity and Coherence

I present a framework based on the concepts of diversity and coherence for the analysis of knowledge integration and diffusion. Visualisations that help understand insights gained are also introduced. The key novelty offered by this framework compared to previous approaches is the inclusion of cognitive distance (or proximity) between the categories that characterise the body of knowledge under study. I briefly discuss the different methods to map the cognitive dimension
