Attack Budgies: leaks from the secret labs of GrrlScientist

This morning I was gravely offended by being described as an “attack parrot”. The offender’s mitigation was that he had originally wanted to call me an “attack budgie”, but had refrained, presumably because he thought an attack budgie sounded less threatening.

Now, it’s little known but a few years ago GrrlScientist actually experimented with breeding attack budgies. They sound all cute and harmless, and indeed on their own they are. But it is as a group they are the menace Grrl requires for her work.

Simple models can lead to generality in ecology

ResearchBlogging.orgIt’s always nice to read a paper that is obviously wrong, but where you have to think about why it is wrong. Because it makes you, well, think. And sometimes learn something new. So when I see a paper in TREE with the title “Do simple Models lead to generality in ecology?“, it’s clear that it’s going to answer “no”, and that I’m going to disagree.

In there paper, Evans and a plethora of co-author present this argument:

[W]e argue that there is usually a trade-off between simplicity and generality, such that simpler models are, all other things being equal, less general than are complex models. For example, a nonlinear population growth equation such as dN/dt = αN + βX1+a represents a large family of models, the members of which correspond to the constant parameters α and β being set to particular values (whereas a can take any value). If β is set to zero, we obtain a simpler linear equation, dN/dt = αN. Obviously, the nonlinear equation includes the linear one as a special case. Thus, the more complex equation represents a larger family of models than the linear ones and, therefore, is more general. It can pick out all the real systems that are described by the linear equation plus a range of others.
(I have slightly changed the equation from what the authors presented, to make my argument clearer. I think the original argument is unchanged, though)

i.e. simple models are less general because they cover less of the model space. Which is odd, because I think this is precisely why a simpler model is more general.

Off to the other side of the world

This is just a brief announcement to explain that as this publishes I should be off on my travels again. This time I’m going further than ever before (no, I’m not travelling by standing on the shoulders of giants). I’m off to…

On the Evolution of Camouflage in Urban Environments

One of my offices is in the Geozentrum in the Goethe University here in Frankfurt. This morning this was on the side of the building:
Today's Mystery Bird
I only saw it because it was flapping about a bit in the wind. If you can’t ID it, then here’s a cropped photo:

Making reviewing boring stuff less boring

Over at the Scholarly Kitchen, everyone’s favourite source material for winding up OA advocates, Phil Davis asked about something only tangentially related: Do Uninteresting Papers Really Need Peer Review?

In it he lays out a view that is perhaps selfish, but understandably so. He outlines why he only agrees to review few papers, and what sort he will review:

For me to accept an invitation to review, a paper has to report novel and interesting results. If it has been circulated as a preprint on arXiv, then I don’t benefit from seeing it a second time as a reviewer. Similarly, the paper must also pique my interest in some way. Reviewing a paper that is reporting well-known facts (like documenting the growth of open access journals, for instance) is just plain boring. Test a new hypothesis, apply a new analytical technique to old data, or connect two disparate fields, and you’ll get my attention and my time.

The only other category of manuscripts that I’ll accept for review are those that are so biased or fatally flawed that it would be a disservice to the journal or to the community to allow them to be published. These papers must really have the potential to do harm (by distorting the literature or making a mockery of the journal) for me to review them.

Which; I guess, means he’s only interested in reviewing a small percentage of papers that come his way. As a journal editor, I find this attitude worrying, but as a potential reviewer, I understand it perfectly: there is only so much time in the day, so I don’t really want to spend it reading boring manuscripts (a plea: if you find yourself wanting to not review a manuscript, please suggest another victim, e.g. a post-doc or senior grad student. That really helps me, and whoever gets to review gets experience).

Davis’ solution to the problem is to suggest that a boring paper doesn’t need to be reviewed fully:

Perhaps all that is needed is to send null and confirmational results through perfunctory editorial review. These articles may only require passing a checklist of required elements before being published in a timely fashion. The result may be a cheaper and faster route to publication, and for some kinds of publications, this is exactly the desired outcome.

As an editor, my reaction to this is “eek”. In the comments, Kent Anderson lays out an important complication:

The purpose of peer review is both to improve the paper and to help it find the right outlet.

But let’s not kid ourselves — not every paper needs to be peer reviewed as rigorously as some, and there is no single thing called “peer review.”

Finding the right outlet is something that editors can certainly help with through a perfunctory review. At Methods in Ecology & Evolution, we receive quite a few papers that are not suited to us, and I try to suggest alternative outlets. But improving a paper is something that often needs more time: someone who knows the areas has to read a paper more carefully, and look for areas where it can be improved. As an editor, I often don’t have enough knowledge about these areas, which is why we ask reviewers.

But I am also sympathetic towards reviewers who agree to review a paper that turns out to be boring papers. The sorts of papers Davis is discussing are ones that are boring because they replicate other work, without adding much novel. So they are a priori identifiable as not terribly exciting, but worthy, and this should influence the choice of which journal the paper is sent to. In particular, somewhere like the Journal of Negative Results – Ecology & Evolutionary Biology might be a typical choice. But given that we already know such a paper is going to be difficult to find reviewers, and is also not going to have a huge impact, can we not try to make them more palatable for readers, without compromising on the reporting of the work? My feeling is soo 2008: Yes, we can.

Most papers we receive at JNR are written like standard papers: an introduction that lays out the problem and the literature, the methods describing a sanitised version of what was done, the results, and finally a discussion explaining why this work is so important that Nature should have accepted it at once. My feeling is that we could improve the readability of papers if we cut down the introduction and discussion massively. This is especially so when the paper is a replication: the intro could be pretty much “We repeat the seminarsemolina work of Gee & Grant, but in the Greater Rumple Horned Snorkack. Read their paper for why this is so interesting”. And the discussion could be similarly brief: “We found similar results, but with a stronger effect of Ewok urine. This might be because of the smaller size of the Greater Rumple Horned Snorkack.” There is probably no need to explain why this is important for global warming: if it was that important, either someone else will have already said it, or you would be publishing the work in a journal with a higher impact factor, like PLOS One.

Would this help? I guess if we told potential reviewers the word count, it might. It also might help to get more negative results published, by making the barrier to writing them up lower. Would losing the text harm science? The only harm I can see is that students writing up negative results might not learn to put their work in context, but one would hope that not all of thesis is like this, and if that was seen as a problem, extra discussion could be added to the thesis rather than the paper.

Is this something we should try at JNR-EEB? And for those of you not in ecology or evolutionary biology, does this sound familiar, or is the tedium of the discussion section one only we face?

How oil companies are helping to combat global warming

I just saw this news that Statoil is to be allowed to drill holes in the bottom of the North Sea:
Now, oil companies (and that’s what Statoil is: it has nothing to do with statistics) are often vilified for being behind global warming, so it’s nice to see them trying to help solve the problem. I thought it was worth explaining how they’re going to do this: luckily last week I met an oil engineer who explained it all to me.

The long and the short of papal reigns

If you’ve been following the news, or twitter, you’ll have noticed that the current pope, Pope Benedict XVI (pronounces Kss-vee) has decided to retire at the end of the month, to spend more time with his twitter account. Anyway, the Grauniad had an interactive thingy up, which, they suggested, “illustrates the idea that a long-serving pope is often followed by one whose papacy is much shorter”. Well, possibly. But you really need to do a bit more than stare at a fancy graphic. You actually need to do some analysis of the data.

A Brief Service Announcement

Sorry for not posting much, um, recently. This is partly because I’ve been busy, and also because I’ve been avoiding writing an obituary for The Beast, who died a few weeks before Christmas. In the words of Trillian, normal service will be resumed as soon as we work out what “normal” is.

Changing ecologists’ statistics to statistics about nature

Whilst my back was turned, I had another paper published online early. It’s rather embarrassing that I didn’t notice, because I’m an Executive Editor for the journal. The paper is, of course, superb (most of the work was done by Konstans, my co-author, not me). But it got me thinking a bit about some of the deeper issues.

Prizes Straight from the Pits of Hell

This should make predicting this year’s science Nobels easier. Last month,
Republican congressman Paul Broun, who also happens to be a member of the US House of Representatives science committee, described evolution, the big bang theory and embryology as ‘lies straight from the pit hell’:

Today one of the Nobel committees got their revenge, giving the Physiology or Medicine prize to work on embryology. Ha, take that!

So, coming up this week: prizes for the Big Bang tomorrow, and chemical evolution on Wednesday. Perhaps Dawkins will get the literature prize on Thursday, just to really wind up the US politicians.

Who, then for the Peace Prize? Any suggestions?
