Last year we “celebrated” the 10th anniversary of the invention of the h-index (also known as the Hirsch factor; Hirsch, 2005), an indicator created by Jorge E. Hirsch, that attempts to measure the achievements of a research scientist. However, it not only appears that h-index has taken on a life of its own but also that the popularity of this formula currently surpasses the initial idea for it...

Four methods for the detection of Trichomonas vaginalis in vaginal secretions from 88 symptomatic patients were compared: wet-mount examination, Kupferberg liquid medium, Hirsch charcoal agar, and the Papanicolaou smear. Hirsch diphasic slants and Kupferberg medium did not significantly differ in sensitivity from direct examination of wet mounts. The Papanicolaou smear identification of trichom...

I propose to sharpen the index h, proposed by Hirsch as a useful index to characterize the scientific output of a researcher, by excluding the self-citations. Performing a self-experiment and also discussing in detail two anonymous data sets, it is shown that self-citations can significantly reduce the h index in contrast to Hirsch’s expectations. This result is confirmed by an analysis of 13 f...
