The literature on computing in organizations assumes that users must be trained to get the most out of using their machines. The natural implication of this assumption is that trained users would differ markedly from non-trained users. Yet in exploratory survey research conducted in a large Southern California company, trained and non-trained microcomputer… (More)
A simple and inexpensive device is described which generates voltage steps or cycles of steps of defined amplitude and duration either automatically (triggered by internal or computer clock pulses) or on manual command. The device facilitates the investigation of the voltage dependence of ion channel currents in patch-clamp experiments.
