Scientific Excellence Georeferenced. The neighborhood matters.

While the current dynamics of Worldwide Science outputs are rising to the surface Research Institutions from developing countries with important results; the location of Institutions holding excellence outcomes, that is, those which represent a truly and significant science advancement does not seem to be changing. Although a formal study would need a detailed analysis by scientific fields, an exploratory analysis of the group formed by the Research Institutions which annually publish 100 scientific papers or more (3,000 worldwide, as indexed in Scopus database) reveals that the resulting geographic distribution has a strong bias which is explained by research spending patterns in different regions of the world. There is a large concentration of institutions in North America, Europe, India, China and Japan, and to a lesser extent, in the southern hemisphere, in Chile, Argentina and more prominently in Brazil, South Africa and Australia.

Neighborhood influence

By depicting Research Institutions grouped into four levels of Normalized Impact (NI), a picture, as the one exposed, of the geographic distribution of Research Excellence around the world is obtained. Taking into account that, with odd exceptions, institutions reaching NI scores higher than the world average (values higher than 1) are concentrated in North America, Western Europe and Australia/New Zeeland, we must conclude that if the geographic bias in Scientific Outputs is high, it is even higher the bias affecting the Scientific Impact.
