Ranking forestry journals using the h-index
An expert ranking of forestry journals was compared with journal impact
factors and h-indices computed from the ISI Web of Science and internet-based
data. Citations reported by Google Scholar appear to offer the most efficient
way to rank all journals objectively, in a manner consistent with other
indicators. This h-index exhibited a high correlation with the journal impact
factor (r=0.92), but is not confined to journals selected by any particular
commercial provider. A ranking of 180 forestry journals is presented, on the
basis of this index.Comment: 21 pages, 3 figures, 5 tables. New table added in response to

Dynamics of Anisotropic Universes
We present a general study of the dynamical properties of Anisotropic Bianchi
Universes in the context of Einstein General Relativity. Integrability results
using Kovalevskaya exponents are reported and connected to general knowledge
about Bianchi dynamics. Finally, dynamics toward singularity in Bianchi type
VIII and IX universes are showed to be equivalent in some precise sence.Comment: 12 pages, 6 figures, Proceedings of the Albert Einstein Century
