The Nine Types of PI

October 21, 2007

See Effect Measure (or revere’s source) for a cartoon on the 9 types of PI. (The original source is apparently “The NIH Catalyst” vol 3, p23, links to the archive for this publication appear to be broken.”) [Minor Update: The comic was republished in Science , as was the same artists "Nine Types of Postdocs".]

Which type of PI are you?

Fascinating data on SfN meeting participation from 2001-2006 is available as a paper placed on arXiv.

An analysis of the abstracts presented at the annual meetings of the Society for Neuroscience from 2001 to 2006

Authors: J. M. Lin, J. W. Bohland, P. Andrews, G. Burns, C. B. Allen, P. P. Mitra

I will always have to reference this as the place I picked up the concept that “we need to practice scientific birth control” in discussion of uninterrupted growth in the neuroscience community.

Other tidbits:

  • 60% of abstract authors only attend a single meeting in the surveyed interval.
  • average of 4.3 authors per abstract
  • La Jolla is in the top ten in each year- Represent!
  • no correlation between SfN attendance and NIH budget
  • six degrees (actually 6.09) of separation confirmed for neuroscientists
  • NIH ICs generally get what they pay for

A reader dropped the blog an email note which, among other things, was interested in a discussion of the concept of “least publishable unit”or LPU.

Apparently this concept is popular enough that Wikipedia has an entry on the “LPU“:

In academic publishing, the least publishable unit (LPU) is the smallest amount of information that can generate a publication in a peer-reviewed journal. The term is often used as a joking, ironic, or sometimes derogatory reference to the strategy of pursuing the greatest quantity of publications at the expense of their quality. … There is no consensus among academics about whether people should seek to make their publications least publishable units.

An Observer piece by Wray Herbert summarizes a recent article in Psychological Science:

Black volunteers who had witnessed unfair but ambiguous hiring decisions performed more poorly on the Stroop test, suggesting that they were using all their mental resources to make sense of the unfairness.

[Blacks]…have developed coping strategies for the most hateful kinds of racism; it’s the constant, vague, just-below-the-surface acts of racism that impair performance, day in and day out.

Salvatore and Shelton 2007 Psychological Science, 2007 Sep;18(9):810-5.


Figure 1 shows Stroop interference as a function of the “prejudice condition” which was manipulated by statements of a purported Human Resources  manager regarding hiring of candidates.

In the ambiguous-prejudice condition, the officer’s comments were neutral with regard to race (e.g., ‘‘good GPA but not business or econ’’), so the reasons for his hiring recommendations were unclear. In the blatant-prejudice condition, his comments explicitly invoked race as a factor in the decision (e.g., …that the Black candidate had been a member of ‘too many minority organizations,’’ and the White candidate was a ‘‘typical white prep-school kid’’), making it clear that the decision
was motivated by bias.

There was also an interaction with the race of the purported “HR manager” such that:

We also observed an interaction between subject’s race and evaluator’s race… indicating that the Stroop results were also determined by the match between subject’s race and the race of the evaluator (and job candidate). Cognitive depletion was attenuated when the evaluative context featured a match between the subject’s race and the human-resources officer’s race (i.e., both Black or both White), and the job candidate was a racial out-group member … Cognitive depletion was exacerbated when the evaluative context instead featured a match between the subject’s race and the job candidate’s race, such that the human-resources officer making the hiring recommendations was a member of the racial out-group…

This is all somewhat relevant to a prior post on Jim Watson’s little dustup.

Notorious arrogant bastard* and Nobel laureate, James Watson shoots off again, this time descending into race/intelligence minefield [Pharyngula, Zuska, denialism blog]. Consequently gets talk cancelled. The ass kick by Greg Laden here and here, pre-empts my need to get into the intelligence literature. Blogosphere and MSM goes nuts for a news cycle or two.

Female Science Professor has a good one on the hoary old “fishing expedition” StockCritique of grant review. “Stamp collecting” is a new one for me though!

Open Access Grantsmanship

October 17, 2007

I was reading one of the summaries of the CSR Peer Review open house roundtable things, from the “Neuroscience” one. A quick Google is coming up dry so if anyone recalls a summary that includes survey data, please comment. The thing that struck me was that over 50% of participants had never had a grant triaged.
