International influence in science: Beyond center and periphery

Abstract The global network of scientific influence has been described earlier as approximating a center and periphery constellation in which national scientific communities are stratified vertically by centrality, influence upon others in general, and centrality of a community has been explained by its creativity. By controlling for centrality, this study goes beyond the center-periphery conception and describes a network of particular influence among communities, segmented horizontally in six geopolitical regions of structurally equivalent communities. Particular influence by one community upon another is explained partly by intelligibility of the community's publications and collegial and educational ties between the communities; ties that are shaped by political-economic affinity, cultural cooperation, geographical propinquity, and language commonality between the countries.
