Extant theoretical work on the political resource curse implies that dependence on resource revenues should decrease autocracies’ likelihood of democratizing but not necessarily affect democracies’ chances of survival. Yet most previous empirical studies estimate models that are ill-suited to address this claim. We improve upon earlier studies, estimating a dynamic logit model that interacts a continuous measure of resource dependence with an indicator of regime type using data from 166 countries, covering the period from 1816-2006. We find that an increase (...) in resource dependence at time t - 1 increases the likelihood of autocratic persistence at t, but has no appreciable effect on democratic survival. We go beyond existing empirical studies to show that increases in resource dependence have persistent and substantial cumulative effects on autocracies' likelihood of becoming democratic over the long-term, showing that the total effect of resource dependence on regime type is much larger than the short-term (one period) effect indicates.

The author narrates briefly the friendship that developed from his instruction of James Dean in the art of photography and documents the Dean personality with exclusive portraits.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Genetic diseases can be every bit as devastating as the diseases caused by bacteria or viruses, and in one way they are much worse: we pass them on to our children, generation after generation after generation. Science and medicine have provided us with clues to the treatment of a few genetic diseases, although by their very nature they have never been considered curable. But, as William R. Clark shows, that is about to change through one of the most profound revolutions (...) in modern medicine: gene therapy, a branch of the new field of molecular medicine. The New Healers is a clear and compelling introduction to a revolution in modern medicine that may lead to cures for cancer, AIDS, and nearly 4,000 previously incurable genetic diseases. Clark introduces us to the scientists working on the vast Human Genome Project, and outlines all the basic elements of molecular biology necessary to understand this remarkable new medicine. (shrink)
