An h-index of X means the author has X publications cited at least X times each — a simple way to combine quantity and quality into a single number. There are some pitfalls in interpreting this type of data. It includes any publication with one author from Iran/Iraq. Some of publications may have only minor contributions from there. Some fields, like Math, Econ or Informatics, tend to be underrepresented because of the way how publishing works in these fields. A world-class mathematician might for example have problems to keep up with a mediocre clinician in terms of publication and citation counts. One can correct for such factors, but the optimal way depends on the objectives of the analysis. Let me know whether these data are useful to you.

A quick analysis of publications from Iran and Iraq shouldn't take long. I could send you something by beginning of next week, and you can check whether the data are helpful. Is that a good way to proceed? All the best Thomas On Fri, 2010-01-22 at 05:16 -0500, Jeffrey Epstein wrote: > thanks thomas„ i very much appreciate your offer to help..
