    And 15!

    Just reached an h-index of 15. Momentarily, and not discounting self-cites.
    I guess it's downhill from here. It was 14 just 5 months ago (and after that, it went down to 13 momentarily). In any case, we'll not drop the guard. You neither. Keep citing. Thanks!

    Congratulations JJ. That's a great impact h-index (have you seen the h distribution curve on the original article by Hirsch). And your Egghe number is good as well. Plus a great responsability. This means that you should work from now on papers with great ideas leading to 16 or more (future) citations! It's not downhill. It's possible. We have done it in the past, we shell keep doing it in the future. I only be worried if I had a h-index = 90 !! That in fact is a big problem (what should a guy like this do next in order to keep his standard ?!).

    Egghe? I didn't know that one.
    I know several with h=90. Goldberg, for instance.

    The Egghe number is considered to be an improved alternative to the Hirsch number, at least to solve some problems the later has. The h-index ignores the number of citations to each individual article beyond what is needed to achieve a certain h-index. Hence an academic with an h-index of 5 could theoretically have a total of 25 citations (5 for each paper), but could also have more than a 1000 citations (4 papers with 250 citations each and one paper with 5 citations). In reality these extremes will be unlikely. However, once a paper belongs to the top h papers, its subsequent citations no longer "count". Such a paper can double or triple its citations without influencing the h-index (Egghe, 2006). Hence, in order to give more weight to highly-cited articles Leo Egghe (2006) proposed the g-index. The g-index is defined as follows:

    Given a set of articles ranked in decreasing order of the number of citations that they received, the g-index is the (unique) largest number such that the top g articles received (together) at least g2 citations.

    Although the g-index has not yet attracted much attention or empirical verification, it would seem to be a very useful complement to the h-index. Here are the references (h* was proposed in 2005 and g** in 2006) - both are online:

    * J. E. Hirsch, PNAS, Vol. 102, no. 46, 2005.
    ** L. Egghe, Scientometrics, Vol. 69, no. 1, 2006.

    Finally this free software automatically computes both indexes: http://www.harzing.com/resources.htm#/pop.htm

    note - g2 above is g^2 or square of g.

    JJ I believe that Goldberg is now on h=96 !! Only inventing again a brand new computational paradigm as he have done in the past with the GA's, could he surpass this incredible index. Not for humans . Only extraterrestrials !

    Yep, I knew that g index. I'll try and compute it...

    No need to. According to the software "Publish or Perish" (freely available: see link above) your g=28.

    Hey, thanks... Yep, I know that one, but it's for windows, and I don't use Windows too much lately.
