Educational and occupational mobility across generations in India: social and regional dimensions
Educational and Occupational Mobility is a cherished dream for all groups of people, more so for those who are at the bottom rungs of society. However, it is often seen that upward mobility is concentrated among the socially well-offs leading to divergence in educational attainment and occupational levels. Such divergence is reflected in earning capabilities as well, thereby aggravating the problems of economic and social inequality. The present paper examines the extent of intergenerational mobility in both educational and occupational attainments for diverse social groups in India to understand the inertia of inequality. A regional dimension is also explored to examine whether patterns are similar or otherwise across the country. Results indicate strong intergenerational stickiness in both educational achievement and occupational distribution among the backward social groups. Occupational mobility is lower than educational mobility indicating that educational progress is not being transformed to occupational improvement and brings up the possibility of discrimination in the labour market. Regional disparities in mobility levels indicate that states in India have had different social processes in force.Intergenerational Mobility; Education; Occupational Choice; Social Disparity; India;
Exploring effects of magnetic field on the Hadron Resonance Gas
We present a study of the effects of magnetic fields on fluctuations and
correlations in hadron resonance gas model. We find significant changes in the
fluctuations of net baryon number, electric charge and strangeness. This is
also reflected in various fluctuation ratios along the freezeout curve
Sustaining supercooled mixed phase via resonant oscillations of the order parameter
We investigate the dynamics of a first order transition when the order
parameter field undergoes resonant oscillations, driven by a periodically
varying parameter of the free energy. This parameter could be a background
oscillating field as in models of pre-heating after inflation. In the context
of condensed matter systems, it could be temperature , or pressure, external
electric/magnetic field etc. We show that with suitable driving frequency and
amplitude, the system remains in a type of mixed phase, without ever completing
transition to the stable phase, even when the oscillating parameter of the free
energy remains below the corresponding critical value (for example, with
oscillating temperature, always remains below the critical temperature
). This phenomenon may have important implications. In cosmology, it will
imply prolonged mixed phase in a first order transition due to coupling with
background oscillating fields. In condensed matter systems, it will imply that
using oscillating temperature (or, more appropriately, pressure waves) one may
be able to sustain liquids in a mixed phase indefinitely at low temperatures,
without making transition to the frozen phase.Comment: 17 pages, 7 figures, Expanded version with more detail
