Most times, when assessing the science in the world, what you do is look at the quantity and quality of research produced by scientists and research centers. Lutz Bornmann Researchers of the Max Planck Society of Munich and Loet Leydesdorff, University of Amsterdam established an alternative method for assessing the performance Scientific cities.
The approach is as follows: take the total number of papers (papers) made by researchers in a specific city, then consider how many of these appear in 10% of most cited papers. "For example, if located in a city authors have published 10,000 papers, one would expect that 1,000 of them for statistical reasons (ie, 10%) were in 10% of the most cited of the world", say the researchers.
After making this calculation, we compared the expected number of most cited papers in real numbers.
then display the results on a map, showing cities with more papers than expected in dark green, while those with less than expected are in red. The bigger the circle, the more papers are involved.
maps were made by measuring papers of physical, chemical and psychology which appeared in 2008 and who were given until February 2011.
In physics, which is the map that is above the best positioned are London, Paris, Karlsruhe, Munich, Pisa and Rome. Worst of all is Moscow, which appears in a giant red circle.
in Latin America do not walk very well, many countries do not even appear. Brazil, Argentina and Colombia seem to have pretty decent rates in physics, chemistry while he goes a little better in Chile. In psychology, however, there are many orange and red circles to our side, except in Mexico where they appear a pair of green spots.
The map has raised questions about how effective it is, however, it is useful to see a lot of information that one is not very clear. Anyway, it is clear that the sciences have much to do still on this side of the pond.
