Modeling the growth of world social science literature

The main objectives of this study are: (a) to find the applicability of selected growth models to the growth of publications in six sub-disciplines of social sciences, namely anthropology, economics, history, political science, psychology, and sociology in the world; and (b) to verify the criteria for selecting the most appropriate growth model suggested by Eggheand Rao (1992).

Obsolescence of literature in the field of psychology

Bibliometric technique of citation analysis was applied to the data of five psychological periodical literature. The distribution of citations frequencies was statistically tested and the obsolescence factors were determined. The relation between the growth and obsolescence has been studied, and it has been observed that “higher the growth of literature, higher the obsolescence as well as higher the half life.”

Modeling the growth of Indian and Chinese liquid crystals literature as reflected in Science Citation Index (1997–2006)

The present paper describes the application of growth models as suggested by Egghe and Ravichadra Rao (Scientometrics 25:5–46, 1992). The scope of the paper is limited to study the growth and dynamics of Indian and Chinese publications in the field of liquid crystals research (1997–2006).

Communication and collaborative research pattern of Sivaraj Ramaseshan: A scientometric portrait

S. Ramaseshan has contributed for the better understanding of various subjects in which he specialized during his years at the Indian Institute of Science, University of Madras and the Raman Research Institute. In this paper we would like to emphasis on his scientific contributions in various journals and some classic papers. In his entire career as a scientist he has collaborated with 47 eminent scientists and students and has published a total of 178 papers during the years 1944–2000. His field of interest has been varied and thus classified into 4 main area, i.e.: Crystallographic studies, Magneto-optics & Optics, Solid State Physics and Miscellaneous topics.

Scientometric portrait of Prof. Peter John Wyllie

SummaryScientometrics is an application of quantitative methods to the history of Science. It is also one of the techniques for documenting, collecting works of eminent scientists and researchers. In this paper, we present a concise sketch of Prof. Peter John Wyllie, stressing on his scientific achievements. His research has had a great impact in the fields dealing with terrestrial magmatic phenomena and geology.
