与时俱进、创新理论是党的建设的基础——学习江泽民同志《论党的建设》

理论建设是党的建设的首要问题。与时俱进、创新理论是马克思主义基本原理的必然要求,是保持党的先进性的客观需要,是党的建设的永恒主题。     

Diagnostics for dependence within time series extremes

Summary. The analysis of extreme values within a stationary time series entails various assumptions concerning its long- and short-range dependence. We present a range of new diagnostic tools for assessing whether these assumptions are appropriate and for identifying structure within extreme events. These tools are based on tail characteristics of joint survivor functions but can be implemented by using existing estimation methods for extremes of univariate independent and identically distributed variables. Our diagnostic aids are illustrated through theoretical examples, simulation studies and by application to rainfall and exchange rate data. On the basis of these diagnostics we can explain characteristics that are found in the observed extreme events of these series and also gain insight into the properties of events that are more extreme than those observed.

墙的变异--试论当代西方建筑流派之变化

任何事物都在发展变化，建筑流派也同样变化着，本文通过对建筑外墙的表象变化的论述，引出建筑流派的变化，阐明这一变化的根源在于建筑哲学的变异，墙的变异可谓当代西方建筑流派变异的“缩影”。

A note on LeCam’s bound for the distance between the Poisson binomial and the Poisson distribution

n possibly different success probabilities p ₁, p ₂, ..., p _n is frequently approximated by a Poisson distribution with parameter λ = p ₁ + p ₂ + ... + p _n . LeCam's bound p ² ₁ + p ² ₂ + ... + p _n ² for the total variation distance between both distributions is particularly useful provided the success probabilities are small. The paper presents an improved version of LeCam's bound if a generalized d-dimensional Poisson binomial distribution is to be approximated by a compound Poisson distribution.

La médiane simpliciale d'Oja: Existence,unicité et stabilité

Oja (1983) examined various ways of measuring location, scatter, skewness, and kurtosis for multivariate distributions. Among other measures of location, he introduced a generalised median known in this paper under the name of the Oja median. In our study of the existence of that median, we show that Oja's definition can only be applied to distributions having a mean. In dimension d θ 2, we establish that the usual method of extension breaks down, which raises the question of the validity of the concept as a notion of median. Two fundamental theoretical properties of that median are also considered: uniqueness and consistency.     

民族地区构建和谐社会应加强对传统多元生态文化的利用和改造

“人与自然和谐相处”是社会主义和谐社会的六个基本特征之一,民族地区构建社会主义和谐社会必须考虑到传统多元生态文化的功能。在开放的、以市场经济为主导的现代社会生态经济系统下,传统多元生态文化的约束力远不如在传统社会生态经济系统中那么有效、广泛。民族地区只有在维护自身生态经济系统可持续运作的基础上,进一步加强对传统多元生态文化的利用和改造,才能充分发挥生态文化的协调功能。因此,民族地区应当在继续维护传统生态文化的多元性、科学性和合理性的同时,根据现行社会生态经济系统的特征,把其改造成为“强生态文化”,构建以科学发展观为基础,具有较强约束力的、适应现行社会生态经济系统的、协调人与自然关系的,包括精神、物质、制度层面的整体文化体系。
