Growth : Are Good Times Good
The relative status of women is poor in the developing world, compared to developed countries. Increases in per capita income lead to improvements in different measures of gender equality, suggesting that there may be market failures hindering investment in girls in developing countries, and that these are typically overcome as development proceeds. Gender inequality in education and health can...
متن کاملTimes, they are a-changing.
Powerful economic forces are threatening the foundations of modern health care. Most western societies can no longer afford all the care that we physicians advocate.

But now, halfway through a business degree, I have a much better answer: “Because the knowledge industry has changed.” As biology is becoming more like other...
متن کاملAre human interactivity times lognormal?
In this paper, we are analyzing the interactivity time, defined as the duration between two consecutive tasks such as sending emails, collecting friends and followers and writing comments in online social networks (OSNs). The distributions of these times are heavy tailed and often described by a power-law distribution. However, powerlaw distributions usually only fit the heavy tail of empirical...
متن کاملMixing times are hitting times of large sets
We consider irreducible reversible discrete time Markov chains on a finite state space. Mixing times and hitting times are fundamental parameters of the chain. We relate them by showing that the mixing time of the lazy chain is equivalent to the maximum over initial states x and large sets A of the hitting time of A starting from x. We also prove that the first time when averaging over two cons...
