[Frank Havemann]

The main problem I have with this paper is:

The weighted "PageRank" algorithm was proposed already in 1978 for citation
networks of journals by Nancy L. Geller (see below).

The difference of Geller and PageRank is only that in the case of journals
normally a damping factor is not needed (lambda = 1).

In the paper by Bollen et al. I have not found any hint for which reason they
need damping and how different damping factors influence their results.
