This study explores the policy options a provincial government might consider in extending health care coverage to the purchase of prescription drugs and dental care. It examines the major public policy objectives involved, such as spreading risk, redistributing wealth, and reducing the barriers to care, and evaluates alternative programs in terms of their costs and efficiency as well as their realization of the basic social objectives of health care. Using varied statistics, some drawn from schemes in other provinces, it estimates what different packages of pharmacare and denticare would have cost in Ontario in 1975. The results indicate that universal coverage may be one of the most costly and least effective options. Based on current modes of service delivery, a universal pharmacare and denticare program would transfer wealth to upper income groups without significantly improving the utilization of health care services.A study of drug manufacturing and retailing systems in Canada and of the structure of dental services suggests that wasteful methods of service delivery could lower per capita costs by 30 to 40 per cent.Potential annual savings in pharmacy and dentistry together in Ontario run into the hundreds of millions of dollars. The authors show how a combination of competitive pressures and selective public intervention can be used to rationalize the delivery system. They caution, however, that such potential savings will be forever unrealized if a public-insurance type of program is introduced which freezes the existing system in place and forecloses the options of either public provision or private market competition.

In contemporary research, the supercomputer now ranks, along with radio telescopes, particle accelerators and the other apparatus of "big science", as an expensive resource, which is nevertheless essential for state of the art research. Supercomputers are usually provided as shar.ed central facilities. However, unlike, telescopes and accelerators, they are find a wide range of applications which extends across a broad spectrum of research activity. The difference in performance between a "good" and a "bad" computer program on a traditional serial computer may be a factor of two or three, but on a contemporary supercomputer it can easily be a factor of one hundred or even more! Furthermore, this factor is likely to increase with future generations of machines. In keeping with the large capital and recurrent costs of these machines, it is appropriate to devote effort to training and familiarization so that supercomputers are employed to best effect. This volume records the lectures delivered at a Summer School held at The Coseners House in Abingdon, which was an attempt to disseminate research methods in the different areas in which supercomputers are used. It is hoped that the publication of the lectures in this form will enable the experiences and achievements of supercomputer users to be shared with a larger audience. We thank all the lecturers and participants for making the Summer School an enjoyable and profitable experience. Finally, we thank the Science and Engineering Research Council and The Computer Board for supporting the Summer School.
