Also this week: assortative mating by major, remembering Bob Paine, Leibig’s Law of the Minimum (productivity), and more.
Jane Lubchenco’s obituary in Nature for Bob Paine.
Terry McGlynn on what most limits the research productivity of PIs at teaching institutions: lack of grad students, technicians, and postdocs, not lack of time. Relevant to recent discussion of correlations between NSERC Discovery Grant evaluations and institution size.
Further to our recent discussion of when researchers peak, new data from a study of sociologists, economists, and political scientists. Goes beyond previous work in accounting for cohort effects, and for considering research outputs besides papers. Finds that productivity increases rapidly until promotion to associate professor, remaining stable thereafter. Unreviewed preprint, which I’ve only skimmed, so caveat emptor.
College graduates don’t just tend to marry other college graduates–they tend to marry college graduates who majored in the same (broadly defined) field. Not too surprising, of course, though I’m a bit surprised at just how strong the effect is: field-of-study homogamy is twice as common as you’d expect if college graduates married at random.

Discussion of Canadian data on the proportion of graduate degree holders in low-paid employment. Yes, that proportion has increased in the last 20 years. No, there’s not a simple story of “overeducation” to be told here.
A journalist on learning to love the economics blogosphere. Don’t know that it applies to any other scholarly field, at least not to the same extent, because the econ blogosphere is much bigger and more active than any other. (ht Tony Yates)
And finally, the Canadian Dept. of Fisheries and Oceans takes a novel approach to managing invasive species.🙂
