Institutional Framework and Poverty: A Transition Economy Perspective
This paper focuses on the role of institutions in poverty alleviation, where both poverty and institutions are interpreted broadly. The broadening of the poverty notion is important at least from the policy perspective. Even if one were convinced that higher growth would reduce income poverty to an acceptable margin, there appears to be little concrete policy measures that one may offer so as to harness greater growth. Besides, the weight of the empirical evidence to date, if not squarely founded on the transition economies of the EEFSU region, is that reducing average poverty is not enough. Existing and possibly rising inequality would ensure that a great many would fall through the cracks, and not benefit from high growth, even if that was achievable. The non-income elements of poverty, on the other hand, are more directly open to influence by policy interventions such as the easing of micro credit and other public and private ventures in health, sanitation, literacy and numeracy fronts. Finally the modest amount of information available at our disposal indicates that the underlying strength of the institutions (economic, political and social) is possibly the single most agent of significance to bring about the alleviation of non-income poverty. There is a further possibility that the same institutional forces would also materially affect the income measure of poverty as well in a discernible fashion.

Effect of van-Hove singularities in single-walled carbon nanotube leads on transport through double quantum dot system
The double quantum dot system with single-walled metallic armchair carbon
nanotube leads has been studied using Non-equilibrium Green function in the
Keldysh formalism. The effect of relative spacing between the energy levels of
the dots, interdot tunneling matrix-element, interdot Coulomb interaction and
van-Hove singularities in density of states characteristics of
quasi-one-dimensional carbon nanotube leads on the conductance of the double
quantum dot system has been studied. The conductance and dot occupancies are
calculated at finite temperature. It is observed that the density of states of
the carbon nanotube leads play a significant role in determining the
conductance profile. In particular, whenever the chemical potential of the
isolated double quantum dot system is aligned with the position of a van-Hove
singularity in the density of states of armchair carbon nanotube leads, the
height of the corresponding conductance peak falls considerably. It is further
observed that the suppression in the heights of the alternate peaks depends on
the relative positions of the energy levels of the dots and their magnitude of
separation.Comment: 16 pages and 16 figure
Breathing Modes in Rotating Bose-Condensed Gas: An Exact Diagonalization Study
We present an exact diagonalization study of the breathing mode collective
excitations for a rotating Bose-Einstein condensate of spinless bosons
interacting via repulsive finite-range Gaussian potential and harmonically
confined in quasi-two-dimension. The yrast state and the low-lying excited
states are variationally obtained in given subspaces of the quantized total
angular momentum employing the beyond lowest Landau level approximation in
slowly rotating regime with . For a given , the low-energy
eigenspectra (bands) are obtained in weakly to moderately interacting regime.
Further, for a given interaction, the split in low-lying eigenenergies with
increasing is the precursor to spontaneous symmetry breaking of the
axisymmetry associated with the entry of the first vortex. With increase in
repulsive interaction, the value of the first breathing mode increases for
stable total angular momentum states L=0~\mbox{and}~N, but decreases for
intermediate metastable states. The position of the observed first
breathing modes in the eigenspectrum remains unchanged as the interaction is
varied over several orders of magnitude.Comment: 5 pages, 3 figures, RevTex two colum
