Impact factors, copyright law, and other science publishing buzzwords

One of my former labmates just sent around the latest list of journal impact factors. I'd repost 'em here, except that I don't want to perpetuate the perception that they are important (although I was grateful to have seen the last version, in a checkout-stand-tabloid-curiosity sense). Here's why:

People seem prone to forgetting that journals have impact factors because individuals papers are cited widely, or not. It's not like every paper that Nature (IF = 28.something) publishes is widely cited, or every paper that Canadian Journal of Earth Sciences (IF = 0.955) publishes is not. In a field as small as sauropod paleobiology, everyone is going to read all of the literature no matter where it is published (the last remaining exception being obscure foreign journals that are not easily available as PDFs; and I mean foreign here as in "outside any researcher's country", not just "outside the US"; getting hold of un-PDFed papers from Oklahoma Geology Notes is probably a cast iron bitch if you're in a local museum in China). The only real advantage of a high-profile journal is to possibly bring the paper to the attention of non-sauropod workers. Whether Nature does that any better than CJES is probably up for discussion (at least in the small world of sauropod paleobiology). Unless some avian physiologist or human bone biomech person is going to have their world rocked by what I write, that 'crossover' appeal is probably not worth stressing over too much.

And there is an entirely different form of impact that we need to be thinking about, which is: how easy is it for people who are interested in your research area to find out about your work and acquire it? I'll bet that my effective impact is much greater than it would be otherwise simply because all of my papers are freely available online (thank you, Mike!). Although individual researchers are doing this more and more--see the badly-in-need-of-updating list here.

And there's a third kind of impact that is arguably more important than either of other two, which is: how big is the intellectual footprint of a given paper? For example, I'd argue that Kristi Curry-Rogers's paper on Apatosaurus ontogeny in JVP has been far more important and influential than her paper on Rapetosaurus in Nature (feel free to argue otherwise, I'm just shooting from the hip here).

Seems to me that what matters for Impact(3) is quality and timeliness of ideas (and timeliness often trumps quality), and publication venue is almost completely irrelevant (although I'd be interested in seeing a counterargument). What matters for Impact(2) is availability of work, which is better for papers that came out in open access journals but easily remedied for papers that didn't (at least until publishers crack down on free distribution of PDFs, if ever*). And Impact(1) is not unimportant, but it's also not nearly as important as people think it is; indeed, Impact(2) and Impact(3) actively erode the importance of Impact(1).

The main thing propping up Impact(1) as something we all have to at least pretend to care about is that the perceived prestige of having published in a high-IF journal really does matter to bean-counters in universities and funding agencies who can't be bothered to assess the actual quality of someone's work and for whom a nice convenient number is a godsend, even if it is horribly flawed. Therefore it also matters to many of us, who can't get ahead without having the approbation of those faceless but immensely powerful entities. See also: student teaching evaluations.

If we're going to be stuck with one number to evaluate something like the impact of a scientific paper, how about the number of citations that pop up on Google scholar? It's fast, free, and doesn't pretend to be anything other than what it is: the number of papers indexed by Google Scholar that cite the paper in question. Tragically, I suspect that ISI impact factors are popular in bureaucracies specifically because they are slow, inaccurate, and not transparently available to all.

* Recently there was a post on the Vert Paleo listserv about how copyright is a barrier to making the existing backlog of literature easily available electronically. My feeling is that those of us needing to get work done will scan what we need ourselves, circulate it through private channels, and keep plowing on. Those who try to stop us with be publicly humiliated at worst (when they come down on us and we all collectively vow never to use their stuff again) or marginalized at best (when we just stop using their stuff because it's harder to get hold of).

Finally, if you haven't been following the blogosphere brush fire (or brush war?) that sprung up in the wake of Nature's pathetically transparent slam of PLoS, Greg Laden has kindly assembled about a million relevant links here.

Discuss.

Putting my money where my open access mouth is

Oh, geez, now that I see it on the page that doesn't look wholesome at all.

No, no, this isn't a post about a new profession as a man-whore (I refuse to blog about that). It's about my theses--BS, MS, and PhD--and the fact that they are now freely available to all. Even the unpublished parts of my diss. I guess if we see a New Mexico Museum bulletin on dinosaur air sacs my naivete will be revealed.

Many thanks to my webmaster, Mike Taylor, whom I owe an improbable amount of good sushi for keeping up my other web presence.

Dr. Vector Sets 'Em Straight: Naming New Taxa Edition

I have to get something off my chest. It is just flat stupid when people name new taxa in theses and dissertations. Let me immediately qualify that: it is just fine to describe new taxa in theses and dissertations. Encouraged, actually. It's a wonderful learning experience. Just don't stick the actual name in. Always in motion is the future, and frankly you don't know for certain whether you are going to get around to publishing the new taxon, or perhaps get creamed by a Mac truck while you cross the road to rescue a kitten. And if you choose the kitten / gruesome death route, or simply get sidetracked by family responsibilities, a job, or whatever, then we'll be stuck with another one of these crappy situations in which a taxon named in a thesis is not properly established in the literature. Maybe never, maybe just not for a long time (Neuquensaurus, anyone?).

Look, I don't mean to beat my chest about how completely awesome I am, but sometimes it just can't be avoided. Here's the Systematic Paleontology section from my undergraduate thesis:

Order SAURISCHIA Seeley 1888
Suborder SAUROPODOMORPHA Huene 1932
Infraorder SAUROPODA Marsh 1878
Family BRACHIOSAURIDAE Riggs 1904
Gen. et sp. nov.
[name to be added in formal publication]

See what I did there? The whole thesis is as close to submission-ready as I could make it*, with this one little difference. Oh, and in the text of the thesis I referred to the animal by the holotype specimen number instead of by the name. That's it.

* The reason it looked so different when it finally came out is that it had been chopped down, reformatted, reviewed three times, and rejected twice before it saw the light of day. Also, I had gotten access to a CT scanner, and that changed things a bit too. Tell you all about it later.

Okay, I can't really take credit for that, Rich Cifelli told me to do it that way. But now I've told you, and you can tell others, and pretty soon this whole problem will be cleared up forever.

Next post: how to fix global warming and prevent dust-bunnies from forming under the couch.
