Of the 498 subjects, 245 had normal glucose tolerance in the first test and were selected at random for...

Peoples' programme A very significant feature of the small-scale irrigation programme is that with a bit of ingenuity and tact it can be made a 'peoples' programme', and the community's active participation can be secured in its implementation. This will not only cut the costs of such schemes substantially, but will also encourage the people to think of these schemes as their own, which is very important to the success of any programme undertaken in the public sector. Obviously such a...

The author examines the South African system of education for Africans in 1980. He finds that the private return to quantity of schooling in 1980 was 6,2%, while the social return to quantity of schooling was 6,0%, and the social return to investment in education quality was 7,9%. Thus there is a growth-equity tradeoff in education spending. He speculates that the political pressures for equality are likely to induce future governments to favour equity above growth in education strategy.
