Links: Reanalyzing R-squares, NSF pre-proposals, and the difficulties of academia for parents

First, Will Pearse has done a great job of looking at the data behind the recent paper looking at declining R and p-values in ecology, and his reanalysis suggests that there is a much weaker relationship between r2 values and time (only 4% rather than 62% as reported). Because the variance is both very large within-years and also not equal through time, a linear model may not be ideal for capturing this relationship.

From the Sociobiology blog, something that most US ecologists would probably agree on: the NSF pre-proposal program has been around long enough (~3 years) to judge on its merits, and it has not been an improvement. In short, pre-proposals are supposed to use a 5 page proposal to allow NSF to identify the best ideas and then invite those researchers to submit a full proposal similar to the traditional application. Joan Strassman argues that not only is this program more work for applicants (you must write two very different proposals in short order if you are lucky to advance), it offers very few benefits for them.

The reasons for the gender gap in STEM academic careers gets a lot of attention, and rightly so given the continuing underrepresentation of women. The demands of parenthood often receive some of the blame. The Washington Post is reporting on a study that considers parenthood from the perspective of male academics. The study took an interview-based, sociological approach, and found that the "majority of tenured full professors [interviewed] ... have either a full-time spouse at home who handles all caregiving and home duties, or a spouse with a part-time or secondary career who takes primary responsibility for the home." But the majority of these men also said they wanted to be more involved at home. As one author said, “Academic science doesn’t just have a gender problem, but a family or women, if they want to have families, are likely to face significant challenges.”

On a lighter note, if you've ever joked about PNAS' name, a "satirical journal" has taken that joke and run with it. PNIS (Proceedings of the Natural Institute of Science) looks like the work of bored post-docs, which isn't necessarily a bad thing. The journal has immediately split into two subjournals: PNIS-HARD (Honest and Real Data) and PNIS-SOFD (Satirical or Fake Data), which have rather interesting readership projections:
