Dividing research into very small chunks...

Research roductivity is most often measured by people who do not have the ability to distinguish good papers from bad papers. Such measurements therefore tend to devolve into mechanical algorithms that count the number of publications and the impact factor of the journal where the research was published, rather than sensible arguments about the merits (or demerits) of the researcher. Evaluating a researcher therefore becomes a "numbers games", where a researcher with a higher number of small papers easily outranks another who has a smaller number of longer, more complex, publications. The race to the "smallest publishable piece of research" increases the number of papers (arguably "good" to the researcher who needs a "good" evaluation) but makes accompanying the literature more difficult, as one has to keep track of ever increasing numbers of papers with dwindling individual importance. It also detracts from the value of research being reported: in my example today, two papers report computations of very similar compounds. The only difference is the interchange of a nitrogen with a phosphorus atom.
A single paper would have been much more useful and important, but research managers would count that as less productive :-(


PS: I happen to disagree strongly with the suggestion, in these papers, of the existence of intramolecular H-bonding, as the angles involved are too small for H-bonds.

Should we suspect any shameless self-promotion in some Impact Factors?

Selecting the journal for your next submission is a decision with lots of variables:

  • how likely is the journal to find your work "sexy" enough?
  • what is its impact factor?
  • how long does the journal take from acceptance to online/paper publication?
  • how desperate are you to get your paper published?




    Ideally, impact factor would be an objective measurement... We all know, however, that the actual relationship between "real journal impact" and the impact factor is not always perfect: a single paper with many citations in a small journal may increase its IF dramatically, even if all other papers in that journal are less cited than the papers form preceding years; citations may be inflated artificially by the authors self-citing themselves to exhaustion, bad papers may be highly cited (e.g. in refutations), etc.
    I have now found (entirely by accident) a journal that increased its impact factor five-fold from 2009 to 2010. That would be surprising in itself. But the real surprise is that in August 2010, this journal published a paper that has thus far received 37 citations, ALL IN THIS SAME JOURNAL.

    You may check for yourselves in Web of Science.. The paper is

    Aman MJ , Karauzum H , Bowden MG , Nguyen TL (2010) "Structural Model of the Pre-pore Ring-like Structure of Panton-Valentine Leukocidin: Providing Dimensionality to Biophysical and Mutational Data" J. Biomol. Struct. Dyn., 28, 1-12



    This is not the only surprise. Other papers with high citations are:

    Tao Y , Rao ZH , Liu SQ (2010) "Insight Derived from Molecular Dynamics Simulation into Substrate-Induced Changes in Protein Motions of Proteinase K" J. Biomol. Struct. Dyn., 28, 143-157 (36 citations, of which 35 in J. Biomol. Struct. Dyn.)


    Sklenovsky P, Otyepka M (2010) "In Silico Structural and Functional Analysis of Fragments of the Ankyrin Repeat Protein P18(INK4c)" J. Biomol. Struct. Dyn., 27, 521-539 (36 citations, of which 35 in J. Biomol. Struct. Dyn.)


    Zhang JP (2009) "Studies on the Structural Stability of Rabbit Prion Probed by Molecular Dynamics Simulations" J. Biomol. Struct. Dyn., 27, 159-162 (36 citations, of which 31 in J. Biomol. Struct. Dyn. and 4 others are self-citations by the author)

Struct. Dyn., 26, 57-64 (35 citations, of which 21 in J. Biomol. Struct. Dyn. and 11 others are self-citations by the author)

    "We are pleased to invite you....."

    The recent trend toward open access science publishing has yielded a very uneven crop of journals. We do have a few respected Open Access-only publications with high quality research (PLoS ONE and many titles on BioMedCentral) but there is also a very large number of publishing firms that email researchers to solicit submissions to brand new Open Access journals. I have received several of these emails, which always claim to have selected me because of my expertise on the topic even though I have often not published anything on it, or even on related subjects. So far, I have received requests to submit reviews to:

  • a special issue on protein biogenesis in "Archaea". (I have studied enzymes of P. furiosus, but never did any on protein biogenesis or post-translational modifications)
  • International Journal of Medicinal Chemistry
  • Recent Patents on DNA and Gene Sequences (I have never done any sequencing, but that did not prevent the editors from considering me an expert on the area ;-)

    This morning I received the most ludicrous example of "scientific" spam: I was invited to present my work on "A tale of two acids: when arginine is a more appropriate acid than H3O+" to the "EPS Montreal International Renewable Energy Forum 2011". Definitely off-topic!
