Does household expenditure on education in India depend upon the returns to education?

This paper analyses whether the amount households spend on education depends upon the returns to education prevalent in the region in which they live. To this end, we estimated rates of return to education separately for boys and girls in 33 states and UTs in India. These rates of return were then included in our education expenditure model. Our results clearly indicated that the rate of return to education was highly significant in increasing the amount spent on education by the household both for boys and girls. However, we find that the impact of this variable is much larger at secondary level and for girls.Education, Returns to education, India, household expenditure.

Is Rural Child Labour Declining in India?

This paper will look at the patterns of child work, schooling and ‘idleness’ across the major states of India and over two years - 1993 and 2004. We analyse two rounds of the NSS dataset to see whether the patterns of schooling and child work have changed over this period or not. The analysis concentrates on the rural sector and finds that the proportion of children in work has increased between 1993 and 2004. While current attendance at school has increased, the proportion of children whose primary activity is schooling has decreased. We hypothesise that this may be because, in a growing economy, there are more opportunities for employment and therefore a larger number of children are likely to combine work and schooling.

A numerical model for Hodgkin-Huxley neural stimulus reconstruction

The information about a neural activity is encoded in a neural response and usually the underlying stimulus that triggers the activity is unknown. This paper presents a numerical solution to reconstruct stimuli from Hodgkin-Huxley neural responses while retrieving the neural dynamics. The stimulus is reconstructed by first retrieving the maximal conductances of the ion channels and then solving the Hodgkin-Huxley equations for the stimulus. The results show that the reconstructed stimulus is a good approximation of the original stimulus, while the retrieved the neural dynamics, which represent the voltage-dependent changes in the ion channels, help to understand the changes in neural biochemistry. As high non-linearity of neural dynamics renders analytical inversion of a neuron an arduous task, a numerical approach provides a local solution to the problem of stimulus reconstruction and neural dynamics retrieval
