This paper uses an extensive dataset compiled by the author to quantitatively study the determinants of academic and industry innovations measured by the numbers of journal publications, patents and Nobel Laureates. I use sensitivity analysis to test the robustness of estimates to specification...

Braun et al. (2006) recommended using the h-index as an alternative to the journal impact factor (IF) to qualify journals. In this paper, a Bayesian-based sensitivity analysis is performed with the aid of mathematical models to examine the behavior of the journal h-index to changes in the...

In this work we investigate the sensitivity of individual researchers’ productivity rankings to the time of citation observation. The analysis is based on observation of research products for the 2001–2003 triennium for all research staff of Italian universities in the hard sciences, with...

Because of the variations in citation behavior across research fields, appropriate standardization must be applied as part of any bibliometric analysis of the productivity of individual scientists and research organizations. Such standardization involves scaling by some factor that characterizes...
