Do Predictor Envelopes Really Reduce Dimension?

They really do go.

While it is technically correct that 70-80% of rural or underserved origin candidates do not go ‘outside’ current concentrations of physicians and health resources, the appropriate statistical analysis reveals that they really do go at rates 2, 4, 6, or 10 times higher than the typical medical students. Others also go, such as the 75% of rural physicians who have urban origins or those with top...

Is there such a thing as a disease? For most doctors, the question may seem absurd, and barely worth a moment’s thought. Yet the question is a legitimate one, and is taken seriously by a range of people from biologists to philosophers. There are many reasons why. For example, as any doctor will recognise, the definitions of many diseases are quite arbitrary. They vary from one place to another,...

Virtual Worlds: do we really need the third dimension to support collaborative learning?

The goal of Computer Supported Collaborative Learning (CSCL) is to enable students to work together, to emphasize and verify their knowledge by reciprocally interacting, and to reinforce their social dimension. Virtual Worlds provide several features to support informal communication and to create communities. They have been adopted by many universities and organizations to support distance lea...

What do scaffold proteins really do?

Scaffold proteins play an important role in coordinating signal transduction cascades. However, their exact mechanism of action and the ultimate effect they have on the signal output remain unclear. Ferrell discusses how computer simulations have provided insight into the multiple possible functions that scaffold proteins may have. What remains is to test the predictions in real cells to determ...
