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 This outdated conclusion, based largely on data from 1995, is dangerously optimistic and belies mounting evidence that documents the significant financial stress now facing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...

The demonstration that information required for the generation of neurons before glia is intrinsic to individual stem cell–derived clones poses the question of mechanism. One possibility is that there is a clock intrinsic to stem cells that determines when daughter cells will be Discussions of CNS stem cell biology often leave the specified to adopt neuronal fates and when they will impression ...

out blow. They found that inhibitors of the earliest stages of autophagosome formation had no effect, but the anti-malaria drug chloroquine, which inhibits the degradative function of autolysosomes, dramatically increased cell death. Affected cells accumulated grossly distorted autophagic vacuoles, lost their mitochondrial membrane potential almost completely, and suffered a large increase in r...

In this paper we make SDRT’s glue logic for computing logical form dynamic. This allows a dialogue agent to anticipate what the update of the semantic representation of the dialogue would be after his next contribution, including the effects of the rhetorical moves that he is contemplating performing next. This is a pre-requisite for planning what to say next. We make the glue logic dynamic by ...

At the three-story high school in his small Oklahoma town, two football players carried him between floors in a ...

It is well known that English sentences containing bare plurals (henceforth BPs) are ambiguous. Under one reading, they can be interpreted as a predication of some property directly of a kind, as in (1a), which says that the kind dog is extinct. Alternatively, they can express some characterizing property of instances of a kind, as in (1b), which says that, in general, individual dogs are intel...

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...
