[MARMAM] google alternative to ISI impact ratings looks good

Publish or Perish is a new citation rating program based on google scholar
that seems to give more sensible results.
I think we are all now aware of the Journal IMpact Ratings game. ISI
pretty much has control of this market and excludes piles of journals from
their analysis. To be included in ISI a journal cannot be over
specialized, it cannot skip an issue or be late or slow, it must be older
than 2 years, it must be cited in current ISI ranked journals, it should
not cite more than 13% of its own articles during the rated interval, its
editorial board ideally has an international component, all articles must
be in eglish, and there are a number of other factors that can disqualify
a journal. The corporate journals have a clear advantage here and they
even encourage authors to cite papers from other journals from their
corporation in order to inflate ratings (yes, its been published!).
Publish or perish (http://www.harzing.com/resources.htm#/pop.htm) is an
alternative to ISI, its free, and it uses the Google Scholar database to
formulate rankings for journals, authors, and even articles.
Granted that scholar isn't complete, but recent analyses reveal it is now
more complete than ISI since ISI only includes cites from ISI journals,
scholarly books, and ignores non-english publications among other factors.
Scholar includes all of these sources, however, it misses some old
articles, although this is changing with the expansion of BioOne, JStore,
etc. So, from a citation analysis point of view, P&P is probably (in my
opinion) more accurate than ISI because it now covers more citations.
I did a few searches in the sciences. PP gies a ton of stats, here are 3.
h-index = similar to the ISI rating, but not limited to last two years
(slightly modified ISI rating)
g-index = similar to h-index, slightly diffent formula
AWCR = age-weighted citation rate, ave # of citations for a paper adjusted
for the age of each paper. Of course, new journals (under 3 yr old) will
rate low no matter what.
First I list some generalized journals then a mess of herp journals by PP
ranking and give their ISI rating in parentheses. If the journal is not
rated it will say NR in the parentheses and if it is too new or defunct,
it will have new or defunct in the paretheses. It is very interesting how
some journals have decent ranking on PP and others are high on ISI. The
rating by PP makes more sense to me. IF anyone thinks otherwise, let me

Subject: [MARMAM] Request for Phocine Distemper Virus reference
SealWatch.org is preparing an Alert page about the current outbreak of
Phocine Distemper Virus in northern Europe, apparently originating again
from the islands of Denmark and potentially spreading to other countries.
Harbor/common seals are at the greatest risk; the last epidemic was
Although we have access to scientific studies on the etiology and
epidemiology of the disease, and are compiling a list of those marine
mammal rescue stations most likely to be involved at the forefront of
response in the near term, we do not have a reference to a general
treatment of the disease for an concerned, informed, but non-technical
audience. Any suggestions for an appropriate online resource to which we
can direct visitors seeking further information would be appreciated.
