Abstract  

Analyses the age of references cited in source papers of the theoretical population genetics speciality at different phases of its development. Discusses the characteristics of specialities in terms of obsolescence measures such as half-life and immediacy index. Explores the applicability of different theoretical probability functions in the age densities of references cited. Concludes that age of references cited is best modelled according to lognormal distribution.

Abstract  

Studies the relation between growth rates and obsolescence rates and half-life of theoretical population genetics literature. Explores the application of lognormal distribution in age distribution of citations over a period of time.

Abstract  

The paper points out that the characteristic properties of general social networks are reflected in co-authorship patterns of theoretical population genetics as studied from 1900 to 1980. The results are consistent with the analyses of bibliographies where the co-authorship networks in invisible colleges probably have shown the same behavioural patterns as the non-scientific populations. The patterns of behaviour are portrayed in two-dimensional as well as three-dimensional representations of co-authorship data in theoretical population genetics.

Abstract  

This paper seeks to provide current indicators on Indian science and technology for measuring the country’s progress in research. The study uses for the purpose 11 years publications data on India and top 20 productive countries as drawn from the Scopus database for the period 1996 to 2006. The study examines country performance on several measures including country publication share in the world research output, country publication share in various subjects in the national context and in the global context, patterns of research communication in core Indian domestic and international journals, geographical distribution of publications, share of international collaborative papers at the national level as well as across subjects and characteristics of high productivity institutions, scientists and cited papers. The paper also compares the similarity of Indian research profile with top 20 productive countries. The findings of the study should be of special significance to the planners & policy-makers as they have implications for the long term S&T planning of the country.

Abstract  

The paper analyses the frequency distribution of scientific productivity of authors active for same lengh of time in theoretical population genetics speciality. The focus of analysis is on two aspects: their actual duration of participation in total research output and the speed at which they are able to produce their research publications.

Abstract  

The Parliament, the highest legislative body in India, plays a significant role in formulating national policies. It is, therefore, pertinent to find the concern the Members of Parliament and different political parties show and the priorities they accord to the S&T related issues. They can judge it statistically through the number of questions raised/asked on the floor of the House. The study presents such an analysis taking the example from the S&T questions raised in the year 1992 during the Tenth Parliament. The analysis has been done by dividing the S&T related issues into 14 socio-economic areas, such as environmental sciences, biotechnology, energy, food and agriculture, health, natural resources, telecommunications, human resource development, etc. and eight policy areas such as technology policy, international collaborations in S&T, etc. The raising of S&T questions jointly by MPs and different political parties through inter-party and intra-party sponsorships has also been studied. Such an analysis may provide an important basis to the managers and policy makers in formulating the S&T policy of a country.

Abstract  

Focuses on the validity of Lotka's law and the negative binomial distribution model to author productivity data in different time periods in theoretical population genetics speciality. Finds out if there is any relation between applicability of a statistical distribution and the development of speciality. Looks at the linkages between inequality/concentration measures and the development of speciality. Explores the relevance and applicability of the two generalisations, namely Price Square, Root Law and 80/20 Rule to the author productivity data and their relation with development of theoretical population genetics. Finally, a study of the growth of practitioners in the field with different productivity levels is conducted, and the emergence of core authors in the speciality is explored.

Abstract  

The study analyses 27018 research papers published by India in condensed matter physics as seen from Science Citation Index-Extended Version (SCIE) (Web of Science) database for the period 1993–1995, 1996–1998 and 1999–2001. The study reports that condensed matter physics is the most sought after branch in physics research in India, accounting for 20% share of the country output in physics. The University & College sector as well as R&D sector are the major contributors to condensed matter physics. However, the country growth in this field, computed on six yearly basis, has still been negative (−1%) compared to 17.4% country growth in overall physics during the same period, 1993–1995 to 1999–2001. The study also maps condensed matter physics research on other dimensions such as institutional productivity, nature of collaboration in research, and institutional specialization. It examines highly cited papers, and lists prominent and productive scientists in this field. It also provides suggestions for accelerating condensed matter research in India.
