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).

Foundation of a Global Interdisciplinary Research Network (COLLNET) with Berlin as the Virtual Centre

The growing importance of collaboration in research and the still underdeveloped state-of-the-art of research on collaboration have encouraged scientists from16 countries to establish a global interdisciplinary research network under the title “Collaboration in Science and in Technology” (COLLNET)with Berlin as its virtual centre which has been set up on January 1st, 2000.The network is to comprise the prominent scientists, who work at present mostly in the field of quantitative science studies. The intention is to work together in co-operation both on theoretical and applied aspects.

Distribution of major scientific and technological achievements in terms of age group — Welbull distribution

A statistical analysis is made of two data sets and it is found that the distribution of major scientific and technological achievements in terms of the age of those achievement makers is Weibull distribution. Pearsonsx 2 test results are satisfactory. This finding holds for different centuries, different nations and different disciplines.A statistical analysis is made of two data sets and it is found that the distribution of major scientific and technological achievements in terms of the age of those achievement makers is Weibull distribution.

Scientific publication activities of 32 countries. — Zipf-Pareto distribution

The paper examines the qualitative as well as quantitative indicators for the assessment of the scientific publication activities of 32 countries, with special attention to the Zipf-Pareto distribution of those indicators. Also discussed is the linear relationship between the number of first authors of scientific papers in a given country and the number of papers it produced. Based on these discussions, a comprehensive indicator combining the merits of quantitative and qualitative indicators is suggested. The ranking of the 32 countries by this indicator is found to follow also Zipf-Pareto distribution.

Chinese-Indian-German Collaboration Results that Provided the Impetus for the Foundation of COLLNET

The collaboration model of Kretschmer was applied to the co-authorshipnetwork of Indian medicine with the aim of being able to observe changes instructure over a period of 30 years. The idea of Liang, on her “Distributionof Major Scientific and Cultural Achievements in Terms of Age” was putin relation to the collaboration model by Kretschmer.
