The article deals with some processes generating increases of research collaboration. The major empirical focus is on the increasing tendency of co-authorship in sociology in Slovenia. Bibliometric analyses, based on two joint national research information systems (SICRIS and COBISS), shows the amount of co-authored publications increased over the last two decades. Blockmodeling of co-authorship networks has shown that the sociologists who are not systematically tied to strongly connected and well-established research groups produce the most excellent scientific publications in their field.

The authors consider two algorithms for establishing partitions of signed networks in terms of relaxed structural balance. One is an older heuristic relocation algorithm available in Pajek and the other is a new exact solution procedure. The former is quite fast, but no global minimum is guaranteed. The new branch-and-bound algorithm is much slower but global minimum is always found. Together, the two algorithms provide a sound foundation for partitioning signed networks and yield optimal partitions.
