Issues such as global warming, ozone depletion, insufficient landfill capacity, and excess packaging are foremost on the minds of consumers. Companies face a myriad of environmental challenges, but they also recognize the opportunities to be gained by implementing responsible marketing action plans.  相似文献

This article examines relationships between receipt of internal administrative information in hospitals, influence over general management decisions, and the extent to which certain organizational characteristics predict the receipt of information by each of the three major groups in hospitals: the board, the CEO, and the medical staff. Using a US national sample of 287 non-profit community hospitals, CEOs were found to receive the greatest amount of information and had highest influence while medical staffs were lowest on both measures. of five major organizational characteristics, hospital size emerged as the single strongest predictor of receipt of information for both boards (beta =?0.28, p 0.001) and medical staffs (beta =?0.42, p 0.001). Overall, the five dependent variables explained 18 per cent of the variance in receipt of information by boards and 28 percent of the variance for medical staffs.  相似文献

Summary The questions which Alan Coddington's posthumous bookKeynesian Economics brings to the fore as well as the thought-provoking (rather than fully acceptable) answers it provides make it worthy of being taken up for further analysis and discussion. This review article is intended to be one possible contribution in this respect. It focuses on the way Coddington's book deals with subjectivist approaches in economics and criticises it for going astray in this respect by adopting a mistaken view on the proper method of economics and giving a mistaken interpretation of both Keynesian economics and the economics of Keynes.I am indebted to L. H. Hoogduin, I. M. Kirzner, J. A. Kregel, S. K. Kuipers, J.A.H. Maks, J. Muysken and J. Pen for their valuable comments and discussion on an earlier version of this paper. Of course, they cannot be blamed for any remaining errors.A. Coddington,Keynesian Economics: The Search for First Principles, George Allen and Unwin, London, etc., 1983. Pp. 129. £ 9.95  相似文献

There is an increasing realization, world‐wide and in Southern Africa, that conservation and development are compatible.

Because human communities in the less developed rural areas are dependent on a renewable group of resources, including soil, water and forests, it is imperative that land use systems that protect these resources are introduced.

The predominance of subsistence agriculture in these areas is the most difficult syndrome of under‐development. An overall rural development strategy is required that integrates human development with resources management Where the population carrying capacity of the land has already been exceeded, a process of rapid villagization/urbanization is required. Village/urban growth and agricultural development require a carefully co‐ordinated programme of land capability analysis and planning, as well as active investment in infrastructure and the introduction of appropriate technologies and institutions.  相似文献

The linkage between development and health is clearly spelt out in the definition of primary health care by the World Health Organisation. There is a widespread and growing disillusionment with the traditional Western approach to health care which fails to meet the real demands of the Third World situation.

This paper looks briefly at conditions in the developing world and the strategy proposed by the W H O to attempt to meet the objective of health for all by the year 2000 and refers to the South African situation.  相似文献
