Recently, Hirsch (2019a) proposed a new variant of the h index called the hα index. The hα index was criticized by Leydesdorff, Bornmann, and Opthof (2019). One of their most important points is th...

Lee, Walsh, and Wang (2015) - based on Uzzi, Mukherjee, Stringer, and Jones (2013) - and Wang, Veugelers, and Stephan (2017) proposed scores based on cited references (cited journals) data which can be used to measure the novelty of papers (named as novelty scores U and W in this study). Although previous research has used novelty scores in various empirical analyses, no study has been published up to now - to the best of our knowledge - which quantitatively tested the convergent validity of nov...

We propose the use of beamplots - which can be produced by using the R package BibPlots and WoS downloads - as a preferred alternative to h index values for assessing single researchers.
This study is intended to facilitate fair research evaluations in economics. Field- and time-normalization of citation impact is the standard method in bibliometrics. Since citation rates for journal papers differ substantially across publication years and Journal of Economic Literature (JEL) classification codes, citation rates should be normalized for the comparison of papers across different time periods and economic subfields. Without normalization, both factors that are independent of resea...
While bibliometrics is widely used for research evaluation purposes, a common theoretical framework for conceptually understanding, empirically studying, and effectively teaching their usage is lacking. In this paper, we develop one such framework: the fast-and-frugal heuristics research program, proposed originally in the context of the cognitive and decision sciences, lends itself particularly well for understanding and investigating the usage of bibliometrics in research evaluations. Such eva...
Wu et al. (Nature 566:378–382, 2019. https://doi.org/10.1038/s41586-019-0941-9) recently proposed a new, citation-based index of ‘disruptiveness’ that is based on a dynamic network measure of technological change. In this study, we present and discuss papers published in Scientometrics between 2000 and 2010 with the highest (positive) disruption index.
