Bibliometric research assessment has matured into a quantitative phase using more meaningful measures and analogies. In this paper, we propose a thermodynamic analogy and introduce what are called the energy, exergy and entropy terms associated with a bibliometric sequence. This can be displayed as time series (variation over time), or in event terms(More)
In this paper, a new indicator called the performance index (p-index) is used to rank a 100 most prolific economists. The p-index strikes the best balance between activity (total citations C) and excellence (mean citation rate C/P). The surprise is that the h-index, which is now universally accepted almost as a canonical tool for research assessment of(More)
In this comment, we re-evaluate an example using a “thermodynamic” paradigm to show how bibliometrics can incorporate normalization into the evaluative process. The motivation for this is the recent exchange in the pages of this journal from two groups that have taken different positions on how normalization should be done.
The h-index has captured the imagination of scientometricians and bibliometricians to such an extent that one can now divide the history of the subject virtually into a pre-Hirsch and a post-Hirsch period. Beyond its academic value, it is now used as a tool for research assessment of individuals, research faculties and institutions and even for comparing(More)
A thermodynamic analogy allows bibliometric research assessment of information production processes to be based on a scalar indicator which is an energy-like term called exergy. Derived from standard indicators like impact, citations and number of papers, the exergy indicator X is a multiplicative product of quality and quantity of a scientist’s or group’s(More)
We propose an indicator to “measure” the extent to which co-publication through international collaboration enhances the value of scientific output of an organisation or agency performing academic research. A second order approach is used which combines a quality proxy (impact) and a quantity or size proxy (number of papers published) to yield a trinity of(More)
Quantitative assessment of information production processes requires the definition of a robust citation performance indicator. This is particularly so where there is a need to introduce a normalization mechanism for correcting for quality across field and disciplines. In this paper, we offer insights from the “thermodynamic” approach in terms of quality,(More)
Quality, Quantity, Performance,… An unresolved challenge in performance evaluation in a very general context that goes beyond scientometrics, has been to determine a single indicator that can combine quality and quantity of output or outcome. Toward this end, we start from metaphysical considerations and propose introducing a new name called Quasity to(More)
