When dying is all that awaits them, more and more people are choosing certain death now rather than uncertain life on medical support systems. But the decision seldom comes easy, as a Newsweek reporter discovers during three weeks with the doctors, nurses, patients and families in an intensive-care ward. A best-selling guide to suicide fires debate over when it is right to let life go--and who should make that choice when the patient no longer can.  相似文献

Technology transfer is the process by which technology originating at one institutional setting is adapted for use in another. A major impediment to the implementation of new technologies to assist with mangerial decision-making problems is a lack of communication between the technology and management communities. Development of a tool designed to bridge the technology transfer gap was the goal of this research. The result is a prototype software package which may be used on an interactive computer terminal by a manager for assistance in designing a decision support system (DSS). The four primary research tasks were:
  1. Develop a conceptual model of the DSS design process.
  2. Select and adapt, or create, appropriate software to mechanize the model.
  3. Develop a knowledge base to describe the interactiveness of various organization variables and managerial decision-making needs.
  4. Collect and analyze interview data and implement resultant production rules on the model.
Tasks 1 and 2 were accomplished first to establish the feasibility of this effort. An interview instrument was developed for Task 3. And, corporate managers from several firms were interviewed to accomplish Task 4. Using this data, a prototype production rule model (called DECAIDS for DECISION AIDS) was constructed which supports managerial decision-making from the EMYCIN production rule system used at Stanford University. The purpose of this article is to introduce the need for a Decision Support System Model. A complete copy of this research can be obtained through University Microfilms International, 300 N.

This article uses a comparative case study approach to relate policy outcomes in terms of family planning to the patterns of political forces observed in the 3 Maghrib states of Algeria, Morocco, and Tunisia. It is suggested that official support for a strong family planning program may be linked to recognition of the problem of low labor absorption and to concrete steps taken to counter the problem. The article discusses different vantage points for approaching the political context of family planning and distinguishes between the use of family planning as an instrument of social policy and as an instrument of economic policy. Ideological reasons for opposition to or support of family planning are then outlined. The colonial experience of the 3 states is differentiated and a chronological account of their family planning programs is provided. The political systems and leadership of the 3 countries are separately discussed in greater detail, after which the influence of elite groups on family planning programs and activities in each country is assessed. Developments in the 3 countries since 1978 are then sketched. The author concludes that the relative importance of policies toward employment and women's status in connection with support for family planning has probably varied over time, with economics playing a greater role in the 1970s. The activities of non-regime political actors were found to be very significant in formulation of population policies in Algeria and Morocco but less so in Tunisia.  相似文献
