Bm. Gupta et Cr. Karisiddippa, Collaboration and author productivity: A study with a new variable in Lotka's law, SCIENTOMETR, 44(1), 1999, pp. 129-134
The paper explores the possibility of using a new variable represented by t
he number of collaborators per author as a substitute for the number of pap
ers in Lotka's distribution to predict the productivity strata. On the basi
s of a case study in theoretical population genetics it is concluded that t
he number of collaborators per author has not proved to be a good substitut
e in the Lotka's distribution, which is in contrast to Qin's results.
