The Core Can Be Accessed in a Bounded Number of Steps
No full textThis paper strengthens the result of Sengupta and Sengupta (1996). We show that for the class of games with nonempty cores the core can be reached in a bounded number of proposals and counterproposals. Our result is more general than this: the boundedness holds for any two imputations with an indirect dominance relation between them.dynamic cooperative game, indirect dominance, core.

High Economic Growth, Equity and Sustainable Energy Development of India
No full textIndia has been experiencing sustained high economic growth in the recentyears. However, there exists substantial amount of unacceptable poverty among the people in the country. The expressions of symptoms of such poverty include among others inadequate educational and health attainment of the people and lack of access to basic amenities like modern clean energy, safe water and sanitation which are crucial determinants of capability development. There exists in fact significant amount of energy poverty among the people, particularly in the rural India which has more than 70% share of its population, in the form of use of traditional inefficient biomass as the primary fuel with injurious health effect and the lack of connectivity of the households with electricity. The eleventh five year plan of India which has recently been initiated has taken the approach of inclusive faster growth for the development of the Indian economy. This paper analyses the implications of this high inclusive growth in respect of the twin challenges of environmental sustainability of the energy use required by such growth and the removal of energy poverty, which have to be addressed in India's energy planning. The paper defines the concept of sustainable development and points out its resource accounting implications in respect of energy related resource use. It focuses in this context on the instrumental role of the efficiency of energy use and energy supply, fuel composition and technology in determining the strength of the linkage between the GDP growth and the growth of energy use and that between the energy use and the pollution intensity of energy. The paper also defines, on the other hand, the notion of energy poverty and discusses the problem of equity and energy development in a dual society like that of India. It then reviews the past trend and pattern of energy use and the future projections of energy requirement and supply with special reference to the twin issues of equity and environmental sustainability. In this context it makes a decomposition analysis of the past energy use and CO2 emissions in India for examining its environmental sustainability and if economic reforms of India could make any impact on it. It makes further a brief review of the methodologies of projections and policy planning for the future energy sector development in India as existing in the recent literature. Finally, the paper discusses certain selected issues of energy security and macroeconomic viability of such energy development in the background of the sustained steep rise of oil prices and high cost of carbon free new technologies. It concludes by highlighting certain policy issues relating to pricing, technology and institution for the attainability of inclusive growth and particularly for meeting the gaps in such attainment that would possibly remain as per the existing alternative projections for the future. However, this paper does not pay any special attention to the climate change related global policy issues that would affect India and gives priority to the national level issues relating to energy equity and energy related environmental sustainability of Indian development.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Interactions of the plant flavonoid fisetin with macromolecular targets: Insights from fluorescence spectroscopic studies
No full textFisetin (3,7,3′,4′-tetrahydroxyflavone) is a bioactive plant flavonoid of immense importance as a potentially useful therapeutic drug, for various free radical mediated as well as other diseases. In a recent paper, we demonstrated the novel uses of the exquisitely sensitive intrinsic fluorescence of this compound to explore its binding characteristics in liposomal membranes [B. Sengupta, A. Banerjee, P.K. Sengupta, Investigations on the binding and antioxidant properties of the plant flavonoid fisetin in model biomembranes, FEBS Lett. 570 (2004) 77-81]. Here, we have exploited this technique to examine its interactions with relevant macromolecular targets, namely double stranded DNA (from calf thymus), and the physiologically important circulatory protein, Human Serum Albumin (HSA). In the presence of DNA dramatic changes are observed in the intrinsic fluorescence behaviour of fisetin. These, along with other relevant supporting spectroscopic data, suggest that fisetin binds intercalatively between the base pairs of DNA. From the studies on fisetin-HSA interaction, the existence of two distinct binding sites are inferred. Furthermore we present evidence for the occurrence of efficient Förster type fluorescence resonance energy transfer from tryptophan to fisetin, indicating that both binding sites of fisetin in HSA are proximal to the unique tryptophan - 214 residue present in the interdomain (between IIA and IIIA domains) loop region of the protein
