I here propose an index that links the number of papers a researcher has published with impact factors (IFs) of the journals that publish these papers. A researcher is said to have an index z if totally z of his/her papers are published in journals with IFs of at least z/2. The z-index, not meant to evaluate, compare and rank scientists, is a number that hopefully conveniently summarizes the nu...

The average age at which U.S. researchers receive their first grant from NIH has increased from 34.3 in 1970, to 41.7 in 2004. These data raise the crucial question of the effects of aging on the scientific productivity and impact of researchers. Drawing on a sizeable sample of 6,388 university professors in Quebec who have published at least one paper between 2000 and 2007, our results identif...

Scientific publications are the standard way for communicating research results and ideas to the scientific community, and thus contribute to the progress in knowledge [1].
