Conclusion The agenda is one of the main structural elements of negotiation, in addition to such questions as site, identification of participants, and elements of timing. Together, they answer the who, what, when, and where questions. As with other aspects of negotiation, the agenda can be used either manipulatively to enhance leverage or to improve the prospects for agreement and the possibilities for mutual gain. In most cases, it will be used both ways, reflecting the nature of negotiation as a mixed-motive situation.Although it can be instrumental to volunteer as a sole source to write the agenda, in most cases it becomes a joint activity to construct a consensual basis for subsequent negotiation. In these situations, agenda-building becomes one of the pre-negotiation activities that set the tone for the relationship (Saunders, 1985). In other situations, the parties may engage in actual negotiation without a formal or written agenda. When this occurs, the risks and uncertainties may be high but the party who appreciates the importance of the informal agenda has a tremendous advantage.Whether one plans it or not, during the course of negotiation the parties will discuss a finite set of issues in some sequence and from a particular perceptual framework. Consciousness of the universality and centrality of the agenda is prerequisite to guiding negotiation to a successful conclusion. William R. Pendergast is Associate Dean at Boston University's Metropolitan College, 755 Commonwealth Ave., Boston, Mass. 02215, where he teaches graduate courses and executive development seminars on negotiation. He is preparing research on power and influence, and on strategic choice in negotiation.  相似文献

Recently a federal court in Georgia ruled that several physicians and several state officials could be sued for state-authorized treatment of a minor over his father's objection. State authorization protects providers only if it is properly obtained and the authorizing official has the power to grant the authorization in the existing circumstances.  相似文献

People die daily in the hospital. Mostly, they die because their illnesses were no longer treatable (natural death). Unfortunately, some people die an unnatural death, in particular, as the result of euthanasia. In contrast to the situation in most countries, in the Netherlands euthanasia is accepted by the courts under strict conditions. It can be very difficult for the legal authorities to establish whether a person has died from natural causes or from suicide, euthanasia, or murder. In addition to the pathologist and the lawyer, the toxicologist also has a number of problems in showing whether euthanasia has been carried out. These can consist of the following analytical problems: (a) interactions--the patients involved have frequently been receiving a large number of toxic and nontoxic drugs simultaneously; (b) identification--not all drugs administered are included in general screening procedures; (c) metabolites--a large number of metabolites may have accumulated toward the end of a long therapeutic regimen; and (d) determination--determination of quaternary muscle relaxants and their various metabolites, as well as other drugs, can be problematic. There are also toxicokinetic problems; because of poor kidney and liver function, low serum albumen, general malaise, and interactions between these factors and other drugs, the kinetics of a given drug can differ from normal. This makes it all the more difficult to determine whether the patient died from an accumulation of medication or from a so-called "euthanetic" drug mixture.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

This paper examines the process by which R&D results funded by the Office of Conservation and Renewable Energy (CE) of the US Department of Energy (DOE) have generated commercial applications. It looks at examples of technology-transfer procedures and activitees across three of CE's component offices that correspond to the major energy end-use sectors: transportation, buildings, and industry. On the surface, the conservation programs would appear to have little strategic consistency and, therefore, lack the clear leadership many seek in a technology-transfer program. However, as an alternative to strategic consistency, one may tailor the technology-transfer approach of each program to its unique circumstances. This paper presents case studies of such tailoring, in which the diversity of approaches mirrors the complexity of the energy end-use markets and the private-public interests that must be negotiated to successfully commercialize energy-saving innovations. The paper discusses the lessons learned about the conditions requiring adaptive design and the structures and practices that have been proven effective.  相似文献

Hamstrung by biases and limited facts, doctors routinely deliver shoddy care to old people. This guide shows how to reject that medical mindset and stay healthy longer.  相似文献
