The Convergence of Digital-Libraries and the Peer-Review Process
Pre-print repositories have seen a significant increase in use over the past
fifteen years across multiple research domains. Researchers are beginning to
develop applications capable of using these repositories to assist the
scientific community above and beyond the pure dissemination of information.
The contribution set forth by this paper emphasizes a deconstructed publication
model in which the peer-review process is mediated by an OAI-PMH peer-review
service. This peer-review service uses a social-network algorithm to determine
potential reviewers for a submitted manuscript and for weighting the relative
influence of each participating reviewer's evaluations. This paper also
suggests a set of peer-review specific metadata tags that can accompany a
pre-print's existing metadata record. The combinations of these contributions
provide a unique repository-centric peer-review model that fits within the
widely deployed OAI-PMH framework.Comment: Journal of Information Science [in press
Supercooperation in Evolutionary Games on Correlated Weighted Networks
In this work we study the behavior of classical two-person, two-strategies
evolutionary games on a class of weighted networks derived from
Barab\'asi-Albert and random scale-free unweighted graphs. Using customary
imitative dynamics, our numerical simulation results show that the presence of
link weights that are correlated in a particular manner with the degree of the
link endpoints, leads to unprecedented levels of cooperation in the whole
games' phase space, well above those found for the corresponding unweighted
complex networks. We provide intuitive explanations for this favorable behavior
by transforming the weighted networks into unweighted ones with particular
topological properties. The resulting structures help to understand why
cooperation can thrive and also give ideas as to how such supercooperative
networks might be built.Comment: 21 page
