Since the early 1970s the issue of euthanasia has been intensely debated in The Netherlands. Through these debates knowledge about medical practices involving the end of life was no longer confined to medical or legal quarters, but became public to a large extent. Following public opinion changes, the legal reaction to euthanasia changed. By prosecuting test cases the public prosecutors allowed the Dutch Supreme Court to formulate specific conditions in which euthanasia would go unpunished. The political debate about changing the criminal law, which still holds that euthanasia is a serious crime, developed at a much slower pace. Several extensive empirical studies were undertaken to gain valid knowledge about the medical practices. This article is concerned with a presentation of the various debates and the changes that took place in the fields of criminal law, politics, and medicine. The main conclusion is the hypothesis that a more open climate for medical practices concerning the end of life allows society to better control these practices. 相似文献

This paper is an attempt to place the forecasting of socio-political variables in the context of actual information needs of industrial companies. Initially discussion is of the effect of socio-political variables upon companies with a review of this significance for decision makers and decision takers. An attempt is then made to categorise existing forecasting techniques in the context of socio-political data whilst regard is paid to the possible effects of socio-political variables on companies. Discussion is then broadened to a consideration of current practice both in the UK and in the USA. Problems implicit in current practice are commented upon and the paper ends with the conclusion that socio-political forecasting is currently significant to many companies and that there is a major potential role for management scientists to play in the development and implementation of appropriate techniques. 相似文献

Fossil fuels are an important source of energy for Ontario Hydro and purchases exceed $100 million per year. This paper describes a computer simulation of the inventory situation over an eight-year period, which is being used to assess the relationship between order flexibility and the target carry-over stocks at the beginning of each shipping season. A simple way of presenting the results for management evaluation is illustrated. Variations of the model are used to assess random influences, such as strikes, and to determine the economic balance between holding costs and stock-outs. 相似文献

The findings reported result from a questionnaire survey, and a number of company interviews. Further questions which need to be answered are identified, and a research project to provide these answers is outlined. 相似文献

The measurement of labour turnover is important both because high turnover is regarded as a sign that something is wrong in a firm and also because quantitative information is important in planning recruitment programmes. This paper describes a statistical technique which has proved useful for the measurement and prediction of turnover. 相似文献

A number of statistical tests have been recommended over the last twenty years for assessing the randomness of long binary strings used in cryptographic algorithms. Several of these tests include methods of examining subblock patterns. These tests are the uniformity test, the universal test and the repetition test. The effectiveness of these tests are compared based on the subblock length, the limitations on data requirements, and on their power in detecting deviations from randomness. Due to the complexity of the test statistics, the power functions are estimated by simulation methods. The results show that for small subblocks the uniformity test is more powerful than the universal test, and that there is some doubt about the parameters of the hypothesised distribution for the universal test statistic. For larger subblocks the results show that the repetition test is the most effective test, since it requires far less data than either of the other two tests and is an efficient test in detecting deviations from randomness in binary strings. 相似文献

This paper attempts to develop a multiobjective model to help policy-makers choose the most appropriate mix of economic policies concurrent with the elimination of serious gaps. Each individual policy attempts to achieve a specific goal or a set of subgoals; but it may hinder the achievement of some other subgoals. To differentiate between the importance of different objectives, the analyst assigns different priorities to each of the given set of subgoals. Three sets of results are provided by three separate computer runs of this model. Each set of results corresponds to one of the three priority structures, and each run indicates quite differing underachievements or over-achievements of individual subgoals. A detailed explanation for each of these deviations (gaps) from the targeted subgoals is attempted in an overall framework and some interactions between various gaps (savings gaps, foreign exchange gap, domestic growth gap, GNP gap, etc.) are also identified. 相似文献

Earlier research has established that the full potential of microcomputers is not being achieved by production management in small companies. Moreover, questionnaire results and in-company interviews were used to support suggested reasons for this situation. This paper reports further work carried out to examine the issues raised in far more detail. Collaboration took place with nine separate companies over a range of applications. Three of these case studies are presented in detail, and general conclusions drawn relating both to these specific studies and to the total collaboration. 相似文献
