Questioning practicality

Practicality of industrial enzymes.

In the late 1960s and early 1970s ‘enzyme technology’ was viewed with the optimism and enthusiasm currently devoted to ‘biotechnology’. With one or two spectacularly successful exceptions, industry as a whole has not welcomed enzyme technology with open arms. Consideration of successful and less-successful processes indicates what industry wants and what it has been able to achieve; considerati...

Reductionism and Practicality

Like most domains of science, the study of the mind has been tackled at many scales of analysis, from the behavior of large groups of people (economics and ecology), to the diffusion of ions across cellular membranes (molecular biology and biophysics). At each of these scales, researchers often believe that the critical phenomena of interest, and the most powerful explanatory constructs and mec...

Safety and Practicality

A lthough still in its infancy, ablation of accessory pathways using radiofrequency energy delivered through a catheter already has an important history. The technique evolved from the demonstration that accessory pathway potentials could be recorded with standard multipolar electrode catheters.' It was only a natural extension of the technique to learn ways to eliminate accessory pathway condu...

Questioning Representations

The role of models in the design of computer systems to support interpersonal and cooperative work is examined. It is argued that the current generation of models over-emphasise determinism at the expense of interpretation in the work process. It is further argued that there are many cases in which designs pass between many different professional groups (office workers, managers, analysts, desi...
