According to Wikipedia (http://en.wikipedia.org/wiki/H-index)
“the h-index is an index that attempts to measure
both the productivity and impact of the published work of a scientist or
scholar. The index is based on the set of the scientist's most cited papers and
the number of citations that they have received in other publications.” If
you quickly scan the average number of citations per scientific journal
article, you are likely to see a range of 5 to 10. Because a few papers are
cited hundreds or thousands of times, there are many papers on the other end of
the distribution that are never cited.
Using myself as an example, my most cited
publication has accumulated 81 citations over the past decade, while 7 of my
papers have never been cited. In contrast, over the past six months, I have made
7 presentations that reached 850 individuals. Recognizing that the h-index does
not reflect the total number of individuals who have actually read a paper, but
rather just those who cited a paper, this isn’t really a fair comparison.
However, giving presentations is an excellent opportunity to enlighten an
interested audience about your research.
