a proposal has been made to install an industrial robot to replace the welder. The cell would consist of the robot, two welding fixtures, and the fitter who loads and unloads the parts. With two fixtures, the fitter and robot would work simultaneously, the robot welding at one fixture while the fitter unloads and loads at the other. At the end of each work cycle, they switch places. The robot would use gas metal arc welding instead of shielded-metal or flux-cored arc welding, but the welding speed would remain the same 300 mm/min. The electrode wire spool must be changed every 10 work parts, which takes 5.0 minutes and is accomplished by the fitter. Determine (a) arc-on time and (b) production rate for this work cell.

Can you identify any problems with the regulatory budget approach? How feasible do you believe it would be to calculate the costs of all the regulations of...

The argument has been made that scientific management has been influential in criminal justice and that, as managers have become more advanced professionally, frontline criminal justice jobs have become more impoverished. How would you suggest that jobs, such as those in probation and parole, be designed to provide for enrichment opportunities while still utilizing risk-assessment instruments, electronic monitors, and other technological advances? Is the deprofessionalization syndrome an inevitable consequence of improvements in the technology of criminal justice?
