Who says teaching hospitals are thriving?

Gerard Anderson, et al., in a recent commentary published in Health Affairs (March/April 1999), concluded that "despite dire predictions, America's teaching hospitals appear to be thriving".' This outdated conclusion, based largely on data from 1995, is dangerously optimistic and belies mounting evidence that documents the significant financial stress now facing teaching hospitals around the co...

Who Says We R0 Ready for Change?

This paper uses a theoretical model of cooperative learning to examine the survivability of communities of learners. A primary assumption in this article is that individualbased learning tends to use local information to increase an individual’s “fitness” while collaborative learning, based on the sharing of information, knowledge, and resources, increases group fitness. We frame our discussion...

Who says you cannot get published?

O ne cannot go past the achievements of the winners of the Ig Nobel awards when it comes to service to medicine and science. The Igs are intended to celebrate unusual and imaginative research and are awarded annually by the science humour magazine Annals of Improbable Research. The aim is to make people think and laugh, and along the way it may spur people’s interest in science, medicine, and t...

Random Networks with given Rich-club Coefficient

In complex networks it is common to model a network or generate a surrogate network based on the conservation of the network’s degree distribution. We provide an alternative network model based on the conservation of connection density within a set of nodes. This density is measure by the rich–club coefficient. We present a method to generate surrogates networks with a given rich–club coefficie...
