A fairer way to rank conservation and ecology journals in 2014

1 08 2014

Normally I just report the Thomson-Reuters ISI Web of Knowledge Impact Factors for conservation-orientated journals each year, with some commentary on the rankings of other journals that also publish conservation-related material from time to time (see my lists of the 2008200920102011 and 2012 Impact Factor rankings).

This year, however, I’m doing something different given the growing negativity towards Thomson-Reuters’ secretive behaviour (which they’ve promised this year to rectify by being more transparent) and the generally poor indication of quality that the Impact Factor represents. Although the 2013 Impact Factors have just been released (very late this year, for some reason), I’m going to compare them to the increasingly reputable Google Scholar Journal Metrics, which intuitively make more sense to me, are transparent and turn a little of the rankings dogma on its ear.

In addition to providing both the Google metric as well as the Impact Factor rankings, I’ve come up with a composite (average) rank from the two systems. I think ranks are potentially more useful than raw corrected citation metrics because you must first explicitly set your set of journals to compare. I also go one step further and modify the average ranking with a penalty term that is essentially the addition of the coefficient of variation of rank disparity between the two systems.

Read on for the results.

Hate journal impact factors? Try Google rankings instead

18 11 2013

pecking orderA lot of people hate journal impact factors (IF). The hatred arises for many reasons, some of which are logical. For example, Thomson Reuters ISI Web of Knowledge® keeps the process fairly opaque, so it’s sometimes difficult to tell if journals are fairly ranked. Others hate IF because it does not adequately rank papers within or among sub disciplines. Still others hate the idea that citations should have anything to do with science quality (debatable, in my view). Whatever your reason though, IF are more or less here to stay.

Yes, individual scientists shouldn’t be ranked based only on the IF of the journals in which they publish; there are decent alternatives such as the h-index (which can grow even after you die), or even better, the m-index (or m-quotient; think of the latter as a rate of citation accumulation). Others would rather ditch the whole citation thing altogether and measure some element of ‘impact’, although that elusive little beast has yet to be captured and applied objectively.

So just in case you haven’t already seen it, Google has recently put its journal-ranking hat in the ring with its journal metrics. Having firmly wrested the cumbersome (and expensive) personal citation accumulators from ISI and Scopus (for example) with their very popular (and free!) Google Scholar (which, as I’ve said before, all researchers should set-up and make available), they now seem poised to do the same for journal rankings.

So for your viewing and arguing pleasure, here are the ‘top’ 20 journals in Biodiversity and Conservation Biology according to Google’s h5-index (the h-index for articles published in that journal in the last 5 complete years; it is the largest number h such that h articles published in 2008-2012 have at least h citations each):

A posthumous citation tribute for Sodhi

6 11 2012

I’m sitting at a friend’s house in Sydney writing this quick entry before jumping on a plane to London. It’s been a busy few days, and will be an even busier next few weeks.

I met with Paul and Anne Ehrlich yesterday (who are visiting Australia) and we finalised the first complete draft of our book – I will keep you posted on that. In London, I will be meeting with the Journal of Animal Ecology crew on Wednesday night (I’m on the editorial board), followed by two very interesting days at the Zoological Society of London‘s Protected Areas Symposium at Regent’s Park. Then I’ll be off to the Universities of Liverpool and York for a quick lecture tour, followed by a very long trip back home. I’m already tired.

In the meantime, I thought I’d share a little bit of news about our dear and recently deceased friend and colleague, Navjot Sodhi. We’ve already written several times our personal tributes (see here, here and here) to this great mind of conservation thinking who disappeared from us far too soon, but this is a little different. Barry Brook, as is his wont to do, came up with a great idea to get Navjot up posthumously on Google Scholar.
