One of these measures is the global clustering coefficient, which measures embeddedness or, more specifically, the likelihood of a triplet being closed by a tie so that it forms a triangle. This article proposes a generalisation of this key network measure to weighted networks.

A paper called Prominence and control: The weighted rich-club effect that I have co-authored was published in Physical Review Letters (PRL). In this paper, we proposed a new general framework for studying the tendency of prominent nodes to direct their strongest ties toward each other.
