Silicosis : geographic changes in research ; an analysis employing density-equalizing mapping

  • Background: A critical evaluation of scientific efforts is needed in times of modified evaluation criteria for academic personnel and institutions. Methods: Using scientometric benchmark procedures and density-equalizing mapping, we analysed the global scientific efforts on "silicosis" of the last 92 years focusing on geographical changes within the last 30 years, specifying the most productive authors, institutions, countries and the most successful cooperations. Results: The USA as the most productive supplier have established their position as center of international cooperation, followed in considerable distance by the United Kingdom, Germany and China. Asian countries, particularly China, catch up and are expected to excel the USA still in this decade. Conclusion: The combination of scientometric procedures with density-equalizing mapping reveals a distinct global pattern of research productivity and citation activity. Modified h-index, citationrate and impact factor have to be discussed critically due to distortion by bias of self-citation, language and co-authorship.
