  Prathap, G.: ¬The zynergy-index and the formula for the h-index.
  In: Journal of the Association for Information Science and Technology. 65(2014) no.2, S.426-427.
  (Brief communication)
  
  Abstract: The h-index, as originally proposed (Hirsch, 2005), is a purely heuristic construction. Burrell (2013) showed that efforts to derive formulae from the mathematical framework of Lotkaian informetrics could lead to misleading results. On this note, we argue that a simple heuristic "thermodynamical" model can enable a better three-dimensional (3D) evaluation of the information production process leading to what we call the zynergy-index.

  Prathap, G.: Measures for impact, consistency, and the h- and g-indices.
  In: Journal of the Association for Information Science and Technology. 65(2014) no.5, S.1076-1078.
  (Brief communication)
  
  Abstract: An altogether different view on the properties of a good performance measure than that given in Egghe (2012) is offered. Egghe argued that a good impact measure should reward nonconsistency; that is, the more citations over papers are unequally distributed, the higher the impact should be. Here, a quantitative proxy for consistency is offered, and it is shown that as consistency increases, the ideal performance measure, which is sensitive to changes in consistency, should increase, reflecting this virtue.

  Prathap, G.: ¬A three-class, three-dimensional bibliometric performance indicator.
  In: Journal of the Association for Information Science and Technology. 65(2014) no.7, S.1506-1508.
  (Brief communication)
  
  Abstract: In this brief communication, we show how a simple 3D bibliometric performance evaluation based on the zynergy-index (Prathap, 2013) can be simplified by the recently introduced 3-class approach (Ye & Leydesdorff, in press).

  Prathap, G.: ¬A thermodynamic explanation for the Glänzel-Schubert model for the h-index.
  In: Journal of the American Society for Information Science and Technology. 62(2011) no.5, S.992-994.
  (Brief communication)
  
  Abstract: Recently, it was shown that among existing theoretical models for the h-index, the Glänzel-Schubert model provides the best fit for a chosen example involving the research evaluation of universities. In this brief communication, we propose a thermodynamic explanation for the success of the Glänzel-Schubert model of the h-index.

  Prathap, G.: Fractionalized exergy for evaluating research performance.
  In: Journal of the American Society for Information Science and Technology. 62(2011) no.11, S.2294-2295.
  (Brief communications)
  
  Abstract: The approach based on "thermodynamic" considerations that can quantify research performance using an exergy term defined as X = iC, where i is the impact and C is the number of citations is now extended to cases where fractionalized counting of citations is used instead of integer counting.
