Dear socnetters,

I'm looking for articles or other types of documents which deal with the
strength of the connections. I have already found this document:

Guido Caldarelli, Fabrizio Coccetti, and Paolo De Los Rios. Preferential
exchange: Strengthening connections in complex networks. Phys. Rev. Lett.,
submitted, 2004.

Do you know other references?

Many thanks.
