A Case Study of the Arbitrariness of the h-Index and the Highly-Cited-Publications Indicator
Michael Schreiber
The arbitrariness of the h-index becomes evident, when one requires q*h instead of h citations as the threshold for the definition of the index, thus changing the size of the core…
How to derive an advantage from the arbitrariness of the g-index
Michael Schreiber
The definition of the g-index is as arbitrary as that of the h-index, because the threshold number g^2 of citations to the g most cited papers can be modified by a prefactor at one…
Empirical Evidence for the Relevance of Fractional Scoring in the Calculation of Percentile Rank Scores
Michael Schreiber
Fractional scoring has been proposed to avoid inconsistencies in the attribution of publications to percentile rank classes. Uncertainties and ambiguities in the evaluation of perc…
Regularization of an autoconvolution problem in ultrashort laser pulse characterization
Daniel Gerth, Bernd Hofmann, Simon Birkholz +2
An ill-posed inverse problem of autoconvolution type is investigated. This inverse problem occurs in nonlinear optics in the context of ultrashort laser pulse characterization. The…
Do we need the g-index?
Michael Schreiber
Using a very small sample of 8 datasets it was recently shown by De Visscher (2011) that the g-index is very close to the square root of the total number of citations. It was argue…
How relevant is the predictive power of the h-index? A case study of the time-dependent Hirsch index
Michael Schreiber
The h-index has been shown to have predictive power. Here I report results of an empirical study showing that the increase of the h-index with time often depends for a long time on…
