Title 



Modelling successive hindices
 
Author 


  
Abstract 



From a list of papers of an author, ranked in decreasing order of the number of citations to these papers one can calculate this authors Hirsch index (or hindex). If this is done for a group of authors (e.g. from the same institute) then we can again list these authors in decreasing order of their hindices and from this, one can calculate the hindex of (part of) this institute. One can go even further by listing institutes in a country in decreasing order of their hindices and calculate again the hindex as described above. Such hindices are called by Schubert [2007] successive hindices. In this paper we present a model for such successive hindices based on our existing theory on the distribution of the hindex in Lotkaian informetrics. We show that, each step, involves the multiplication of the exponent of the previous hindex by 1/á where á > 1 is a Lotka exponent. We explain why, in general, successive hindices are decreasing. We also introduce a global hindex for which tables of individuals (authors, institutes,...) are merged. We calculate successive and global hindices for the (still active) D. De Solla Price awardees.
