运用可拓工程理论及其应用探讨事物的可拓性,以求发现解决矛盾问题的研究方向。对这一方向的研究逐步形成了可拓论,它以物元理论和可拓集合论为支柱,它的应用方法称为可拓工程方法,包括可拓信息方法、可拓系统方法、可拓决策方法等。本文着重阐述可拓工程方法以及在经济领域、管理、控制领域和人工智能中的初步应用。 相似文献

Abstract Purpose: This article outlines the development of extension as a discipline in Australia, its organization, and the ideological changes that have occurred from the second half of the nineteenth century through to the present. Design/Methodology/Approach: It considers the evolution of extension across the different states of Australia from a national perspective and describes how the research development and extension (RD&E) complex has rotated through cycles of crises, highs, awakenings in thought and practice, and periods where achievements and institutions unravel. Findings: Discussed is the tension between public and private sector extension, as well as the successes and failures of various paradigms. It considers the impacts of different agricultural policy on Australian agricultural RD&E across the decades. In particular it deals with the current ‘unravelling’ of the agricultural RD&E system in Australia, and tries to anticipate future demands on agricultural extension and how these services might be delivered into the future. Practical Implications: The article challenges the reader to consider the discipline of extension as a subset of the greater society in which it exists. It provides an insight into how the agricultural research, development and extension capacity of a nation can be observed to ebb and flow over generations in accord with the rhythm of society. Originality/Value: The article presents a perspective that has not been fully captured or understood until now. 相似文献

Abstract The aim of this study was to understand the role that agricultural consultants in New Zealand were undertaking in the Research, Development and Extension (RD&E) system—and in particular in relation to environmental extension. New Zealand does not have a public extension service and hence there is a strong reliance on consultants and regional councils for environmental management information and advice. As they are independent of the formal RD&E system there is no guarantee that RD&E outcomes are reaching farmers, nor that effective environmental extension is occurring. The study used a combination of case studies, phone interviews with informed persons and a national web survey to explore the role of the consultant. The study found that agricultural consultants are playing an important role in working with farmers to improve agricultural production. There are, however, indications that gaps have developed over time between agricultural consultants and the agricultural research sector which limit the effectiveness of the RD&E system. Agricultural consultants are playing a minimal role in proactive environmental extension because insufficient market forces are driving this role. The paper suggests that a national database of agricultural consultants could improve the flow of tailored information between research and agricultural consultants and also suggests mechanisms where consultants could be better integrated into the RD&E system and provide feedback to research programs. Market failure in the area of environmental extension could be addressed by publicly funded incentive programs. 相似文献

在企业发展过程中,面对激烈的市场竞争,需要不断推出新的产品来替换升级原有产品,或者拓宽经营领域,生产与原有产品有较大差异的产品。而对于推出的新产品,首先面临的产品的品牌问题:是创建新的品牌,还是采取品牌延伸策略?品牌延伸策略涉及的有关问题,以及实施该策略的程序和做法等应当深入探讨。 相似文献
