Technological Revolutions

In skill-biased (de-skilling) technological revolutions learning investments required by new machines are greater (smaller) than those required by preexisting machines. Skill-biased (de-skilling) revolutions trigger reallocations of capital from slow(fast-) to fast(slow-) learning workers, thereby reducing the relative and absolute wages of the former. The model of skill-biased (de-skilling) re...

Metamorphoses : The Myth of Evolutionary Possibility

Metamorphoses Through Lie Group Action

We formally analyze a computational problem which has important applications in image understanding and shape analysis. The problem can be summarized as follows. Starting from a group action on a Riemannian manifold M , we introduce a modification of the metric by partly expressing displacements on M as an effect of the action of some group element. The study of this new structure relates to ev...

Patterns of Rape in Ovid's Metamorphoses

The subject of rape is pervasive throughout Ovid's Metamorphoses. The myths themselves are by no means originals of the poet; however, his treatment of these stories is remarkably divergent from his predecessors' in that he provides a uniquely female perspective by outlining both the victim's suffering and the barbaric nature of the perpetrator.
