后现代文化观

后现代文化作为后工业社会人类拥有的一种生存状态、精神样式和美学实践,其目的、性质、对象、形式、内容、功能和价值都发生“哥白尼式”变化。一种健全的、非祛魅的、更多尊严和更多自主性的文化将是非异化的、人道的、自由的、多元的、反本质主义的、非决定论的多种文化形式的混合体。特别是第四世界文化将日益超越政治、国家、阶级、种族、意识形态和宗教信仰,真正实现自在和自为的统一;构建高质量的人文生态,塑造完整人性。

The likelihood ratio test for homogeneity in finite mixture models

The authors study the asymptotic behaviour of the likelihood ratio statistic for testing homogeneity in the finite mixture models of a general parametric distribution family. They prove that the limiting distribution of this statistic is the squared supremum of a truncated standard Gaussian process. The autocorrelation function of the Gaussian process is explicitly presented. A re‐sampling procedure is recommended to obtain the asymptotic p‐value. Three kernel functions, normal, binomial and Poisson, are used in a simulation study which illustrates the procedure.     

A Class of Convolution‐Based Models for Spatio‐Temporal Processes with Non‐Separable Covariance Structure

Abstract. In this article, we propose a new parametric family of models for real‐valued spatio‐temporal stochastic processes S ( x , t ) and show how low‐rank approximations can be used to overcome the computational problems that arise in fitting the proposed class of models to large datasets. Separable covariance models, in which the spatio‐temporal covariance function of S ( x , t ) factorizes into a product of purely spatial and purely temporal functions, are often used as a convenient working assumption but are too inflexible to cover the range of covariance structures encountered in applications. We define positive and negative non‐separability and show that in our proposed family we can capture positive, zero and negative non‐separability by varying the value of a single parameter.     

Transformation and Smoothing in Sample Survey Data

Abstract. We consider model‐based prediction of a finite population total when a monotone transformation of the survey variable makes it appropriate to assume additive, homoscedastic errors. As the transformation to achieve this does not necessarily simultaneously produce an easily parameterized mean function, we assume only that the mean is a smooth function of the auxiliary variable and estimate it non‐parametrically. The back transformation of predictions obtained on the transformed scale introduces bias which we remove using smearing. We obtain an asymptotic expansion for the prediction error which shows that prediction bias is asymptotically negligible and the prediction mean‐squared error (MSE) using a non‐parametric model remains in the same order as when a parametric model is adopted. The expansion also shows the effect of smearing on the prediction MSE and can be used to compute the asymptotic prediction MSE. We propose a model‐based bootstrap estimate of the prediction MSE. The predictor produces competitive results in terms of bias and prediction MSE in a simulation study, and performs well on a population constructed from an Australian farm survey.     

论《墨子》的政治辩证法思想

《墨子》政治辩证法思想的主要内容 ,一是运用“爱民”和“明罚”统治手段实现民众与统治者一致的思想 ;二是下同于上与上同于下相统一的“尚同”思想 ,以及谏臣可以“长生保国”的思想 ;三是“利之中取大 ,害之中取小”的政治决策思想 ;四是“安危治乱 ,在上之发政”、“强必治”等发挥主观能动作用的思想 ;五是“官无常贵而民无终贱”的政治地位转化的思想。《墨子》政治辩证法思想与“得之下情则治”及“非命”的唯物主义思想倾向直接相关。     

A strong law of large number for negatively dependent and non identical distributed random variables in the framework of sublinear expectation

Abstract

In this article, in the framework of sublinear expectation initiated by Peng, we derive a strong law of large numbers (SLLN) for negatively dependent and non identical distributed random variables. This result includes and extends some existing results. Furthermore, we give two examples of our result for applications.     

PVT筒中气液两相非平衡过程的数值模拟

目前国内外多采用平衡后各组分逸度系数相等的平衡判据来描述两相中各个组分的分配情况，但该法无法进行两相由非平衡初始状态达到平衡状态这一非平衡热力学过程的研究。针对这一问题，提出了引入扩散方程来描述液相和气相各个组分由接触到稳定过程的方法，建立了描述两相非平衡态扩散过程的数学模型，提出了分阶段求解模型的求解算法，并运用该法对PVT筒中气液两相系统由接触到稳定过程的状态进行了分析，得出系统全程压力变化规律及平衡状态下随高度变化的甲烷浓度分布规律。计算结果与实验数据对比验证了该方法的可行性，从而为非平衡态相变问题的分析提供了新的思路。     

Local press meets transnational activism: news dynamics in an anti‐WTO protest

Transnational protests often involve a cross‐cultural encounter between “foreign” protesters and the local media and public, whose repertoires of contentious practices and discourses may differ. Examining how transnational and local actors interact in these events is one way to understand the significance and impact of transnational activism. At the same time, local media coverage of transnational protests can also be analyzed as such a cross‐cultural encounter. Following these premises, this article examines Hong Kong media coverage of the transnational protests during the World Trade Organization's 6th Ministerial Conference, which was held in the city in December 2005. The analysis focuses particularly on how this non‐routine news event provided the conditions for a more reflective interactive dynamics between the protesters and journalists, which contributed to emergence of media discourses negotiating and redefining the existing cultural understanding of protest actions. However, the case study also shows the limits regarding how far the redefinition and negotiation can go. Theoretical implications of the analysis are discussed.
