The Medieval River Trade Network of Russia Revisited
By Forrest R. Pitts
Social Networks, Vol.1 (1978/79)
Abstract: Medieval trade and communication along the rivers of Russia are considered as a social network. Two measures are presented. An intermediate node occurrence rate (Shimbel’s stress index) provides a measure of centrality. The short-path distances to all other places are summed to provide a system effort measure of accessibility. Both measures show Moscow to have been most central and accessible with aggregate least effort.
