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

针对BP神经在变压器故障诊断中用于模式识别时,存在训练准则和分类准则不一致而导致的样本识别率降低和网络训练速度缓慢的问题,采用了可拓学的扩缩变换,通过在输出空间中用一个特定的区域(称作教师区域)来代替教师信号,然后将可拓神经网络用于变压器故障诊断中。通过实例证明,可拓神经网络模型的训练速度有了极大提高,模式识别问题得到彻底解决。 相似文献

在多义词的几个意义中,由本义派生出来的意义叫引申义。而词义的引申派生是一种有规律的运动,是按一定的方式和顺着一定的脉络实现的。词义引申的根据和方式主要有相似类比、相关借代和相因推导;词义引申的脉络主要有＂放射式引申＂、＂连锁式引申＂和＂综合式引申＂;词义引申的基本规律是由具体到抽象、由个别到一般、由部分到全体、由实词到虚词。 相似文献

Abstract This study was designed to determine the value of the Southern Region Cooperative Extension Program Leadership Network in the United States. Of particular interest was determining the value added by the network for individual extension administrators, their state organizations, and the southern region. The researchers conducted a series of focus groups and an electronic survey of the members of the Southern Region Cooperative Extension Program Leadership Network to determine the value of the network. The Program Leadership Network was found to provide great value for the vast majority of study participants at the individual, team, and organizational levels. This value included enhancing individual performance, encouraging critical thinking, catalyzing best practices, providing opportunities for leadership and skill development, enhancing the relationship between extension programmes, and serving as a think tank for regional and national initiatives. Extension and programme administrators in other regions and countries should examine leadership networks to determine if they are adding value to extension work. Development of a network similar to the Southern Region Cooperative Extension Program Leadership Network could improve individual, team, and organizational effectiveness. This is especially true for enhancing multistate, regional, and national programming. Extension systems and workers will find value in this study since the results indicate that networking of extension workers enhances personal, team, and organizational performance. A secondary value includes the increased number of multistate, regional, and national coordination of extension programming efforts. 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

ASCTRACT This study aims to analyze the potential and constraints of group-based extension approaches as an institutional innovation in the Vietnamese agricultural extension system. Our analysis therefore unfolds around the challenges of how to foster this kind of approach within the hierarchical extension policy setting and how to effectively shape and enable learning groups. The analysis draws on qualitative data from case studies of five newly established extension groups in Son La province, collected between 2007 and 2008. Content analysis was applied as the main analytical tool. The basic principles of group-based learning approaches are still underdeveloped, mainly due to a non-supportive institutional environment and a command-and-follow mentality. Extension groups suffer from an insufficient distinction between social processes and technical procedures. Finding an appropriate balance between enhancing leadership and supporting collective responsibility is identified as key to sustain groups. The research identified room for adjustments in group-organizational issues since the external institutional environment is hard to change. The particular value of this paper lies in addressing how to organize group-extension approaches in the context of reformed extension systems in a transitional socialist setting. 相似文献

Abstract The study focused on constraints affecting the utilization of Information and Communication Technologies (ICT) for agricultural extension activities by Agricultural Extension Officers in Nigeria's Niger Delta Region. Data were derived from 160 extension officers affiliated to both public and private extension organizations in four states of the Niger Delta. Findings revealed important specific constraints to include: poor ICT infrastructure development, high cost of broadcast equipment, high charges for radio/television presentations, high cost of access/interconnectivity and electricity power problems. The use of Factor Analysis aided to crystallize identified constraints into three factors of ‘poor enabling environment’, ‘lack of access’ and ‘dissemination of unrelated information’. Against the background of several national government initiatives to develop the infrastructure base of the country, recommendations are proffered to ameliorate ICT use constraints. 相似文献
