Scientists from the University of Granada and the Spanish National Research Council—members of the SCImago research group—have found that, worldwide, there are three major ‘clusters’ of countries, defined by the thematic areas they investigate and that their governments invest in most.
The study, published in Plos One, analysed the scientific production of more than 80 countries over more than 10 years (1996-2006)
They conclude that the first cluster is made up of Western Europe, together with the USA, Canada and the petrol-rich Arab Emirates. Together, they form the Biomedical cluster, which is characterized by its democratic regimes. The governments of these countries understand that research into health has electoral benefits because it improves the quality of life of their citizens, says Victor Herrero-Solana, Professor of Information and Communication at the University of Granada and one of the authors.
