This looks good. Modes of collaboration in modern science: Beyond power laws and preferential attachment by Stasa Milojevic, School of Library and Information Science, Indiana University.
Abstract – The goal of the study was to determine the underlying processes leading to the observed collaborator distribution in modern scientific fields, with special attention to nonpower-law behavior. Nanoscience is used as a case study of a modern interdisciplinary field and its coauthorship network for 2000-2004 period is constructed from the NanoBank database. [Etc., etc., etc.]
