This paper explores the Confucian and the Taoist conceptions of mind and knowledge, polarises the two recent approaches in Western multimethodology, and suggests that differences between the two approaches can be channelled to form a creative tension like that between the yin and yang, so that each can improve and enrich itself more consciously and spontaneously through mutual challenging and mutual learning. 相似文献

Modern systems thinking has paradoxes implicit in its theories and these are present because of the relationship between the concept of system and the concept of reality. This paper explores those concepts by looking at five different perspectives within a phenomenological view of reality. Checkland's methodology is criticized for its treatments of systems and reality. Implications for practice are discussed. 相似文献

AHP中判断矩阵一致性修正的模式识别法 总被引:12,自引:3,他引:12
基于模式识别原理,给出了判断矩阵一致性修正的一种方法。在该方法中,首先把由专家或决策者给出的判断矩阵A转化为n个具有完全一致性的正互反阵。再将这n个正互反阵和A分别转化为反对称阵B(i),i=1,…,n和B。在B(i),i=1,…,n生成的线性空间中寻找与B最贴近的正互反阵B~*,将B~*对应的满足完全一致性的正互反阵A~*作为A的修正矩阵,同时得到了A~*对应于最大特征值n的正特征向量的计算公式。 相似文献

During the last 13 years, a dialogue has been conducted in the Critical Systems literature on the subject of choice betwen
methods. However, in the late 1980s and early 1990s, researchers went in two separate directions. One direction involved an
exploration of the “creative design of methods.” This is when the problem situation is understood in terms of a series of
systemically interrelated research questions, each of which might need to be addressed using a different method, or part of
a method. A synthesis is generated that allows each individual research question to be addressed as part of a whole system
of questions. The other research direction involved the development of “Total Systems Intervention” (TSI), a meta-methodology
that, amongst other things, encourages the creative exploration of the problem situation prior to the choice of methods. One
of the latest innovations in TSI is a theory of the “oblique” use of methods. This is the use of methods for purposes other
than those they were originally designed for. However, it is argued here that all the case studies that have been subject
to an “oblique” interpretation can be better explained if they are seen as examples of the creative design of methods. We
can therefore bring together the two strands of research that have hitherto been pursued separately in the Critical Systems
literature. it is suggested that TSI can be enhanced by an understanding of the creative design of methods because the latter
allows us to explain the purposive, flexible, and responsive way in which TSI is most successfully used in practice. 相似文献

To the transformation F(a(s))=a(s)/d^s,this paper brings out two kinds of ways to ascertain parameter d, one way, we let d be arithmetic average of class ration inverse, namely d1=1/n-1(y^(0)(2)/y^(0)(1)+y^(0)(3)/y^(0)(2)+y^(0)(4)/y^(0)(3)+…+y^(0)(n-1)/y^(0)(n-1)+y^(0)(n)/y^(0)(n-1).The other way, we let d be geometric average of class ration inverse, namely d2=(y^(0)(n)/y^(0)(1))^1/n-1.Through the close theory testifying, we find that the model given by this paper has white exponential law coincidence property, that is to say, if we build the model to the normal index, the result has not model error. At the same time, this paper points out, the request d 〉 1 is not appropriate to monotone decreasing series; even precision of model will decrease. 相似文献

As part of the 2001 Census, the One Number Census project estimated and adjusted the Census database for underenumeration. As a result of the highly innovative One Number Census and the Quality Assurance process it encompassed, it was also ensured that robust results could be obtained for each local authority area. This article examines some of the issues and analyses that were undertaken as part of that assessment of the 2001 Census population counts for England and Wales. The article firstly highlights the key issues surrounding the implementation of the 2001 Census fieldwork. The article then explores the 2001 Census results through a series of demographic analyses to illustrate the sorts of issues investigated during the One Number Census Quality Assurance process itself. These analyses look at the patterns contained within the results, and comparisons with key alternative sources of population counts. Overall, these in-depth analyses and investigations provide further credence to the plausibility of the One Number Census results. 相似文献

This paper explores the practice of mindfulness, both formal and informal, in the context of the systems sciences. The systems sciences have given great importance to scientific research, almost to the exclusion of intuitive/spiritual search. However, with the recent worldwide interest in intuitive/spiritual search in general, and mindfulness and mindfulness meditation in particular, the doors have opened for a more balanced combination of these two enterprises. This balanced approach will not only help us to know how and why things happen the way they do, but will also tell us something about how to manage our own selves, particularly in difficult times. Mindfulness, which is the opposite of mindlessness, is our capacity for awareness and for self-knowing. It can be further refined through the practice of mindfulness meditation. The practice of mindfulness and mindfulness meditation has rapidly spread around the world and in the mainstream of Western culture in the past thirty years, thanks in part to an increasing number of scientific and medical studies, proving its abundant beneficial effects. 相似文献

集中式多雷达系统维数不匹配处理技术 总被引:3,自引:0,他引:3
在集中式多雷达跟踪系统中,经常存在雷达的观测信息维数不一致的情况。为了能正确对所有雷达观测数据进行融合,系统需要首先对维数不匹配的观测数据进行处理。目前,通常采用降维的方法处理数据维数不匹配问题。由于在降维处理过程中,需要丢失目标的高度信息,因此,系统会产生一定的动态误差。当目标的俯仰角度比较大时,系统的跟踪精度必然会下降。针对降维方法的缺点,本文采用升维的方法对数据维数不匹配进行处理,并对这两种方法在不同情况下的跟踪精度进行了仿真分析。 相似文献

This article contributes both quantitatively and qualitatively to the discussion on implementation of business ethics, as a basic background of social responsibility leading to systemic behaviour. In the frame of business ethics the ethical core values, culture, ethical climate, informal, and formal measures of business ethics implementation is addressed. The article is also aimed to improve understanding of importance of (ethical) corporate governance, key stakeholders’ influence on the enterprise’s core values, culture, the ethical climate, and informal and formal measures of business ethics implementation as the constitutional elements of enterprise ethical behaviour. The article briefs important cognitions of various empirical researches on business ethics in the case of Slovenian enterprises. The business ethics strongly relates to, and matters in, achieving more enterprises’ social responsibility and humankind’s well-being. 相似文献
