An application of the extended cross impact method to generating scenarios of social change in Japan

Scenarios of Japanese society in 2000 are obtained by applying an extended correlational cross impact analysis. Since the scope of the scenarios is extensive, a procedure is developed to generate the scenarios that consists of a preprocessing of the events of interest and a step-by-step application of a cross impact method. Three scenarios are described, based on a workshop where the procedure was applied.     

发言摘登

这次会议讨论的是一个很重要的题目──国企转型与企业文化构建。我们现在对企业文化的认识,如果同10年前相比,可以说是跨越了一个世纪。当时感觉企业文化是个新鲜东西,并不知道它有多大用途,好像很时髦,多数人对它的认识还是狭窄的、浮面的。10年后的今天,经过理论界的探索研究,特别是经过企业界的创新实践,使得我们对企业文化的认识有了很大的发展。中外企业文化杂志社利用庆祝创刊10周年的机会,组织大家共同研讨国企转型与企业文化构建,这个题目选得非常好。当前,企业文化在中国的需求,很重要的一点就是与国企转型联系在了一起。企业文化…     

The entropies: Some roots of ambiguity

Entropy concepts have developed in four general contexts—thermodynamics, communication theory, statistical information theory and social and life sciences. These concepts have five distinct mathematical forms. Ambiguity and complexity in utilization of the concept has been heightened by this multi-faceted heritage. Effective utilization may be strengthened by a sharper articulation of entropy through combinations of literal, mathematical and graphical modes of expression. Geography and planning as user disciplines have important responsibilities in enhancing cross-disciplinary communication of this important adisciplinary concept. Implications of these arguments for the social sciences include the need for caution in drawing social analogies from the ambiguous entropy concepts of statistical mechanics; and an indication of the potential benefits of social science models based on the unambiguous entropic constructs of statistical information theory.     

Robustness to the unavailability of data in block designs

We present general results for finding or boundingt _maxB , the maximum number of arbitrary whole blocks of observations which can be removed from a block design, and still leave all of the elementary treatment contrasts estimable. The block sizes may be larger than the number of treatments. The results are applied to BBDs, reinforced BIBDs and BBDs, BTIBDs, and a series of variance balanced incomplete block designs with two block sizes. Also given for most of these designs, are results fort _max, the maximum number of arbitrary, scattered observations that can become unavailable, and still leave all of the elementary treatment contrasts estimable.The work was undertaken while Dr. Whittinghill was visiting Ohio State University, and supported by a grant from the Natural Sciences Division, Colby College, Waterville, Maine.     

论提高我国本土会计师事务所竞争力的策略

国际四大所并购我国本土所的趋势已经开始显现,在这种情况下我国会计师事务所需要分析本行业的竞争现状。本文通过分析表明,我国会计师事务所既有优势、机会,也存在极大的劣势、危胁。笔者认为我国会计师事务所要采取完善公司治理、“产品”差异化、专业化、品牌化、人才、审计质量与风险控制等策略,以提高我国会计事务所的竞争力。
