I saw the first two paragraphs of this quote from an interview of Hal Varian by The McKinsey Quarterly over at Statistical Modeling, Causal Inference, and Social Science. The whole interview is great, but this section suggests the promise of macroecology (and… OK… statistics as well) for training people in the broadly important area of acquiring, manipulating, analyzing and understanding large quantities of data:
I keep saying the sexy job in the next ten years will be statisticians. People think I’m joking, but who would’ve guessed that computer engineers would’ve been the sexy job of the 1990s? The ability to take data—to be able to understand it, to process it, to extract value from it, to visualize it, to communicate it—that’s going to be a hugely important skill in the next decades, not only at the professional level but even at the educational level for elementary school kids, for high school kids, for college kids. Because now we really do have essentially free and ubiquitous data. So the complimentary scarce factor is the ability to understand that data and extract value from it.
I think statisticians are part of it, but it’s just a part. You also want to be able to visualize the data, communicate the data, and utilize it effectively. But I do think those skills—of being able to access, understand, and communicate the insights you get from data analysis—are going to be extremely important. Managers need to be able to access and understand the data themselves.
The third paragraph (the part not discussed at SMCISS) speaks to a challenge that we are really still grappling with in ecology:
You always have this problem of being surrounded by “yes men” and people who want to predigest everything for you. In the old organization, you had to have this whole army of people digesting information to be able to feed it to the decision maker at the top. But that’s not the way it works anymore: the information can be available across the ranks, to everyone in the organization. And what you need to ensure is that people have access to the data they need to make their day-to-day decisions. And this can be done much more easily than it could be done in the past. And it really empowers the knowledge workers to work more effectively.
This challenge is the easy access to data by those doing the science, those evaluating the science, and those attempting to apply science to address major socioecological issues. Data is increasingly available, but it is in a wide variety of formats, hosted by different providers, and much of it comes with strings attached. This, combined with a general lack of appropriate technical skills among practicing ecologists, puts us at a disadvantage for tackling important problems and doing so in the most general and useful ways. To be sure, these problems are being addressed by a variety of groups, but we still have a lot of work to do. Perhaps the promise of ruling the world (and the fear of missing our 10 year window) will help keep us moving forward.

Yesterday’s post made me think of this great scene between Michael Douglas and Katie Holmes’ characters in the movie Wonder Boys:
Hannah Green: Grady, you know how in class you’re always telling us that writers make choices?
Grady Tripp: Yeah.
Hannah Green: And even though you’re book is really beautiful, I mean, amazingly beautiful, it’s… it’s at times… it’s… very detailed. You know, with the genealogies of everyone’s horses, and the dental records, and so on. And… I could be wrong, but it sort of reads in places like you didn’t make any choices. At all.

It is increasingly common for journals to employ fairly strict length limits on submissions. I’m actually a big fan of this. I feel that the most important points of most manuscripts will fit into 6-8 published pages and details that only a small fraction of an already small readership will be interested in can easily be placed in online supplements. Keeping papers short forces authors to write succinctly and makes it easier to manage the overwhelming amount of literature being published every year.
That said, I’ve recently been running into a catch 22 with respect to these limits. The issue stems from the fact that in order to make a full blown research paper short, you have to make some tough decisions. In the course of conducting your research you’ve almost certainly explored more ideas and checked out more details than will fit in 6-8 printed pages, so you can’t include it all. Making these decisions is a good thing. It forces the authors to focus on what’s really critical to the paper. This can be a difficult task to learn but it is important for effective scientific communication in the modern era.
The catch 22 occurs because reviewers almost always request that additional information be added to manuscripts. Sometimes this information is important, but often it is not necessary to the manuscript and includes such things as analyses that are largely tangential, more discussion of the reviewers area of research, more citations, etc. The reviewers almost never consider the length issue (which is OK) so they don’t typically recommend anything to remove, and the the AE sends the paper back with a form letter asking the authors to incorporate the reviewer comments. The authors do this because they want the paper to be accepted and send it back but… oops… now the paper is too long. So, for the paper to be submitted to and published in the journal it has to be shorter than the limit, but in order for it to be accepted it has to be longer than the limit.
In a recent experience at Ecology satisfying the reviewer comments caused the manuscript to go from being the length of a Report to being the length of an Article. This would have meant that that the article was no longer open access and would have cost us an additional $1000 for the color figures (color is free for Reports). Fortunately the Managing Editor and I got it worked out with some last minute trimming (David Baldwin is a really nice guy btw). In an even more classic catch 22 (with a journal whose name I will leave out to protect the guilty) we were asked by a reviewer to move material from the supplement to the body of the ms. We made this change, which caused us to go over the figure limit, and then the journal wouldn’t even allow us to resubmit. They unsubmitted our ms and told us to cut down to the appropriate number of figures. It was awesome.
So if we’re going to keep these strict length limits in place for revisions as well as original submissions, and I think we should, then the burden falls on the AEs to consider the length limits of the submission when requesting revisions. If the AEs could provide guidence to the authors when a revision is requested as to whether they deem particular additions of sufficient importance to cut something else, and if so, provide some guidence as to what should be cut, I think it would take care of this problem. But, that is probably a lot to ask, so until then I guess I’ll just keep combining two figures into a single two-panel figure and tightening my writing (which always seems to have space to give).
