Spectator matter fragmentation in Au+Au reactions: Phase space analysis

Clusterization in phase space has been analyzed for peripheral Au+Au reactions at 1000 AMeV using simulated annealing clusterization algorithm (SACA). We investigate how these fragments are correlated in phase space and compare our model calculations with minimum spanning tree (MST) method. Our theoretical study highlights the importance of binding energy criterion in recognizing the fragment structure. MST method however, fails to break-up the spectator matter effectively and thus under-estimates the multiplicity of intermediate mass fragments (IMFs).Comment: 2 pages, 2 figure

A model for cage formation in colloidal suspension of laponite

In this paper we investigate glass transition in aqueous suspension of synthetic hectorite clay, laponite. We believe that upon dispersing laponite clay in water, system comprises of clusters (agglomerates) of laponite dispersed in the same. Subsequent osmotic swelling of these clusters leads to increase in their volume fraction. We propose that this phenomenon is responsible for slowing down of the overall dynamics of the system. As clusters fill up the space, system undergoes glass transition. Along with the mode coupling theory, proposed mechanism rightly captures various characteristic features of the system in the ergodic regime as it approaches glass transition.Comment: 12 pages, 1 figures.

The Disadvantaged Incumbents: Estimating Incumbency Effects in Indian State Legislatures

This paper estimates the effect of a candidate’s incumbency status on his or her chances of winning using a large dataset on state legislative elections in India during 1975-2003. I use an innovative research design, called Regression Discontinuity Design (RDD), that provides unbiased estimate of the effect due to incumbency by comparing the candidates in closely fought elections, and find that incumbency has a significant negative effect on the fortunes of incumbent candidates in India and the incumbency effect has decreased further in the last decade. Also, the variation in the incumbency effects across Indian states depends on the differences in levels of public good provision such as the health facilities, rates of employment and poverty, and state per capita income.Anti-incumbency; Indian elections; regression discontinuity design (RDD)

Trade Competitiveness, Subsidies and Barriers to Trade:Implication for Indian Agriculture

Agriculture in India is the most important segment of the economy. Growth of Agricultural sector is crucial for Indian economy as it employs two-third of its population and contributes nearly one-third of national income. However its importance in the economic, social and political fabric of India goes well beyond what is indicated by its contribution to the economy. The large number of poor agricultural households and their income vulnerability are major concern among policy makers. These concerns have driven both agricultural policies and public expenditures in agriculture in India as well as in other part of the globe. India made significant advances towards achieving its goal of rapid agricultural growth, improving food security, and reducing rural poverty during the last four decades. Sustainable food production growth enabled India to achieve foodgrain self sufficiency, eliminating the threat of famines and acute starvation in the country. More rapid agricultural productivity growth, as past experiences shows, can have major impacts on poverty reduction trough direct effects on producers income, indirect effects on consumer welfare trough changes in food prices, employment and wage effects, and growth induced effects throughout the economy. Agriculture is also one of the major sources of export earnings of our country and is crucial for improving the balance of payments. In recent years, the export of agricultural and allied products accounted for about one-fifth of total export earnings of India. India's share of agricultural export has remained very low in many commodities despite inherent strength of Indian agriculture with the exception of few commodities. The performance of agricultural export depends not only on adequate surplus, international prices, quality of product, market competition and comparative advantage of producing the exportable commodities but also on domestic and international trade policy. Hence the subsidies and supports to agricultural commodities of country play a major role to stand in international market. Present paper is an effort to evaluate competitiveness of Indian wheat and rice in international market. Keeping in view the overall foodgrain production, marketable surplus and number of farmers, among the major foodgrain producing states, Uttar Pradesh has been taken for comparison of trade competitiveness. Since agricultural trade is highly distorted due to huge subsidies and support to agriculture in developed countries; paper also evaluate competitiveness of these commodities in alternative case if both countries withdraw their subsidies to these commodities in form of Producer Support Estimate (PSE). The Paper is divided in four parts; Part one is about the methodology to calculate competitiveness. Trade competitiveness of wheat and rice at normal prices and at PSE adjusted prices has been calculated in part two. Part three evaluate the implications of agricultural subsidy and part four is the concluding part with suggesting some corrective measures for fair agricultural trade and due space of developing countries in international agricultural trade.Trade competitiveness, Subsidies, WTO, Indian Agriculture
