A paradigm shift is taking hold in American higher education. In its briefest form, the paradigm that has governed our colleges is this: A college is an institution that exists to provide instruction. Subtly but profoundly we are shifting to a new paradigm: A college is an institution that exists to produce learning. This shift changes everything. It is both needed and wanted. (See chart compar...

Gamma-glutamyltransferase (GGT), regarded as a marker of excessive alcohol consumption or liver disturbances, is an enzyme catalyzing the first step in the extracellular degradation of the antioxidant glutathione (GSH) and may take part in atherogenesis. The marked relationship between GGT and the atherosclerotic process has shifted attention to the issue of whether its serum levels can aid in ...

In multiuser MIMO networks, the spatial degrees of freedom offered by multiple antennas can be advantageously exploited to enhance the system capacity, by scheduling multiple users to simultaneously share the spatial channel. This entails a fundamental paradigm shift from single user communications, since multiuser systems can experience substantial benefit from channel state information at the...

INTRAOPERATIVE management of blood glucose concentration in patients with diabetes mellitus has traditionally focused on avoidance of profound hypoglycemia or hyperglycemia. In contrast, the relative importance of strict perioperative regulation of blood glucose within the normal range has received little emphasis, in large part because the benefits and risks of such a strategy have yet to be c...

In recent years deep packet inspection (DPI) has often been cited as a major factor in the debate concerning net neutrality. Packet inspection (PI) enables a profound analysis of the contents of IP-packets, especially with respect to the application layer and private data. To protect against this sort of privacy invading attack users are usually advised to encrypt as much of their data as possi...

A paradigm is an accepted world view. If we do not continually question our paradigm then wider trends and movements will overtake the discipline leaving it ill adapted to future challenges. This Special Issue is an opportunity to keep systems thinking at the forefront of ergonomics theory and practice. Systems thinking prompts us to ask whether ergonomics, as a discipline, has been too timid? ...

In just a few months, we will have known about the AIDS pandemic for 20 years. Initially, the HIV epidemics, and the official public responses to them, were defined through a medical paradigm traditionally applied to infectious disease control. If people were aware of risks and were given the means to protect themselves from these risks, it was believed, the epidemics would be tamed. Safe sexua...
