Globalisation in the network of science in 2005:
The diffusion of international collaboration and the formation of a core
group <http://www.leydesdorff.net/cswagner07/index.htm>
Caroline S. Wagner & Loet Leydesdorff
International collaboration as measured by co-authorships on refereed papers
grew significantly from 1990 to 2005. International communications in
science can best be studied as a network, since there is no political
institution mediating relationships at that level: links self-organize
largely through contacts made by scientists. As such, science at the
international level shares features with other complex adaptive systems
whose order arises from the interactions of hundreds of agents pursuing
self-interested strategies. Communications at the international level
appears to have grown significantly in the 1990s, with the addresses of many
more countries evident in collaborative articles. By 2005, global
communications appear to have reinforced the formation of a core group of
highly cooperative countries. This core group can be expected to use
knowledge from the global network with great efficiency, since these
countries have strong national systems. Countries at the periphery may be
disadvantaged by the strength of the core.
