论邓小平"一国两制"思想中的辩证法

邓小平运用“两点论”和“重点论”相结合的辩证方法 ,提出了一系列实现国家统一的正确指导原则 :“一国两制”要讲两个方面 ,其中大陆社会主义是主体方面 ;“一国两制”也要讲两个“长期不变” ,其中大陆社会主义制度永远不变是前提 ;实现“一国两制”要有“两手”。以和平方式为主、不承诺放弃非和平方式的方针 ,不仅适用于实现国家统一的过渡时期 ,而且适用于维护国家长期和平统一的未来

有效激励高职院校非正式群体——基于“双因素理论”的实践

高职院校中的非正式群体分为积极型、消极型和中性型,由美国心理学家赫茨伯格创立的"双因素理论"发现了成就、认可、学习本身等富有激励作用的因素,为人们选择激励手段和激励方式提供了参考。在管理过程中要根据具体的特点来确定是采用保健因素来消除其不满,还是用激励因素来促使其更满意,这样我们才能充分发挥非正式群体的积极作用,遏制其消极作用,真正达到管理的目的。     

Fractions of permutations. An application to Sudoku

We study how to simplify fractional factorial design generation by exploiting the a priori knowledge that can be derived from the orthogonality constraints that the fractional factorial design itself must satisfy. We work on Sudoku puzzles that can be considered as a special case of Latin squares in the class of gerechte designs. We prove that the generation of a Sudoku is equivalent to that of a fraction of a proper set of permutations. We analyse both the 4×4 and the 9×9 Sudoku types.     

ON THE DESIGN OF FIELD EXPERIMENTS UNDER A ONE-DIMENSIONAL NEIGHBOUR MODEL

This paper examines the effect of randomisation restrictions, either to satisfy conditions for a balanced incomplete block design or to attain a higher level of partial neighbour balance, on the average variance of pair-wise treatment contrasts under a neighbour model discussed by Gleeson & Cullis (1987). Results suggest that smaller average pairwise variances can be obtained by ignoring requirements for incomplete block designs and concentrating on achieving a higher level of partial neighbour balance. Field layout of the design, although often determined by practical constraints, e.g. size, shape of site, minimum plot size and experimental husbandry, may markedly affect average pairwise variance. For the one-dimensional (row-wise) neighbour model considered here, investigation of three different layouts suggests that for a rectangular array of plots, smaller average pairwise variances can generally be obtained from layouts with fewer rows and more plots per row.

王元化《文心雕龙讲疏》解读--《讲疏》的文本结构与治学方法研究之一

王元化的《文心雕龙讲疏》出版于20世纪90年代。此前,他出版了《文心雕龙创作论》。此文先阐述其《创作论》的创作契机,再解读其《讲疏》文本结构的三个环节,后解读王元化研究《文心雕龙》的治学方法。王元化《讲疏》的治学方法是由考证推理方法论、说明研究方法论和分析综合方法论等三种方法论整合而成的。这对我们的科学研究仍然有启迪效应。     

The new strategy for the concise presentation of sampling errors in the Italian Structural Business Statistics Survey

Reporting sampling errors of survey estimates is a problem that is commonly addressed when compiling a survey report. Because of the vast number of study variables or population characteristics and of interest domains in a survey, it is almost impossible to calculate and to publish the standard errors for each statistic. A way of overcoming such problem would be to estimate indirectly the sampling errors by using generalized variance functions, which define a statistical relationship between the sampling errors and the corresponding estimates. One of the problems with this approach is that the model specification has to be consistent with a roughly constant design effect. If the design effects vary greatly across estimates, as in the case of the Business Surveys, the prediction model is not correctly specified and the least-square estimation is biased. In this paper, we show an extension of the generalized variance functions, which address the above problems, which could be used in contexts similar to those encountered in Business Surveys. The proposed method has been applied to the Italian Structural Business Statistics Survey case.
