珍珠遗产历久弥新--2005中国镇江赛珍珠学术研讨会综述

在纪念中国抗日战争、世界反法西斯战争胜利60周年前夕,历史文化名城镇江第三次举行赛珍珠学术研讨会,纪念中国人民的朋友、美国女作家赛珍珠诞辰113周年.来自海内外逾百位专家学者研究和探讨了这位1938年诺贝尔文学奖得主的文学创作的题材特性、主题意蕴及艺术构成;考察和评估了她当年反映我国抗日斗争的文学作品、支持中国人民抗日的政论言论以及大量卓有成效的援华抗日活动的功绩;思考和展望了她所留给我们的遗产,在今天全球化和本土化趋势并存发展的语境下,其跨文化的独特经历及对文化多元共存、互相尊重的认识所具有的特殊价值和深远意义.

美国"新经济"对中国的启示

美国“新经济”是以现代高新技术为基础的知识密集型经济,具有与传统经济相比的新的特征,带来了美国经济的繁荣和发展。在面临全球经济一体化的形势下,美国新经济对促进中国经济的发展和提高国际竞争力都有一定的借鉴和启发意义。     

蝴蝶翩翩梦寰宇——谈老庄思想与几位英美作家的心灵契合

老庄思想自古是中国知识分子遭受挫折后藉以调节心理，安顿生命，养护心灵的哲学，老庄著作自19世纪末翻译成英文传入西方后受到了学术界的广泛关注，并进入一些著名作家的创作视野。文章撷取了奥尼尔、王尔德、毛姆三位英美作家的代表作品加以分析，综合评述了有关他们的创作与道家思想的某些契合关系，揭示出他们各自生活中不同的精神创伤是老庄思想与他们取得共同的心灵契合的原因。     

美国资本主义经济发展中的契约自由与合同法

合同法是美国法律体系中最重要的柱石之一 ,契约自由是美国资本主义社会的一个重要标志。但美国合同法走过的历史道路也许不能简单地概括为从意愿论的胜利到合同的死亡。 2 0世纪的美国合同法面临重重挑战 :立法入侵、行政机构权力的扩大、大公司的发展、经济的复杂化和不确定性、社会各阶层对公平的要求。为了应对这些挑战 ,美国合同法进行了重大调整。这些调整最重要的目标就是使合同法具有适应社会经济变化的更大的灵活性和更高的公平标准。     

Two-stage Huber estimation

In this paper we propose a new robust estimator in the context of two-stage estimation methods directed towards the correction of endogeneity problems in linear models. Our estimator is a combination of Huber estimators for each of the two stages, with scale corrections implemented using preliminary median absolute deviation estimators. In this way we obtain a two-stage estimation procedure that is an interesting compromise between concerns of simplicity of calculation, robustness and efficiency. This method compares well with other possible estimators such as two-stage least-squares (2SLS) and two-stage least-absolute-deviations (2SLAD), asymptotically and in finite samples. It is notably interesting to deal with contamination affecting more heavily the distribution tails than a few outliers and not losing as much efficiency as other popular estimators in that case, e.g. under normality. An additional originality resides in the fact that we deal with random regressors and asymmetric errors, which is not often the case in the literature on robust estimators.     

Generalized Laplacian approximations in Bayesian inference

This paper presents a new Laplacian approximation to the posterior density of η = g(θ). It has a simpler analytical form than that described by Leonard et al. (1989). The approximation derived by Leonard et al. requires a conditional information matrix R_η to be positive definite for every fixed η. However, in many cases, not all R_η are positive definite. In such cases, the computations of their approximations fail, since the approximation cannot be normalized. However, the new approximation may be modified so that the corresponding conditional information matrix can be made positive definite for every fixed η. In addition, a Bayesian procedure for contingency-table model checking is provided. An example of cross-classification between the educational level of a wife and fertility-planning status of couples is used for explanation. Various Laplacian approximations are computed and compared in this example and in an example of public school expenditures in the context of Bayesian analysis of the multiparameter Fisher-Behrens problem.     

Test for homogeneity in Hardy–Weinberg normal mixture model

The phenotype of a quantitative trait locus (QTL) is often modeled by a finite mixture of normal distributions. If the QTL effect depends on the number of copies of a specific allele one carries, then the mixture model has three components. In this case, the mixing proportions have a binomial structure according to the Hardy–Weinberg equilibrium. In the search for QTL, a significance test of homogeneity against the Hardy–Weinberg normal mixture model alternative is an important first step. The LOD score method, a likelihood ratio test used in genetics, is a favored choice. However, there is not yet a general theory for the limiting distribution of the likelihood ratio statistic in the presence of unknown variance. This paper derives the limiting distribution of the likelihood ratio statistic, which can be described by the supremum of a quadratic form of a Gaussian process. Further, the result implies that the distribution of the modified likelihood ratio statistic is well approximated by a chi-squared distribution. Simulation results show that the approximation has satisfactory precision for the cases considered. We also give a real-data example.

Generalized quasi-likelihood

The quasi-score function, as defined by Wedderburn (1974) and McCullagh (1983) and so on, is a linear function of observations. The generalized quasi-score function introduced in this paper is a linear function of some unbiased basis functions, where the unbiased basis functions may be some linear functions of the observations or not, and can be easily constructed by the meaning of the parameters such as mean and median and so on. The generalized quasi-likelihood estimate obtained by such a generalized quasi-score function is consistent and has an asymptotically normal distribution. As a result, the optimum generalized quasi-score is obtained and a method to construct the optimum unbiased basis function is introduced. In order to construct the potential function, a conservative generalized estimating function is defined. By conservative, a potential function for the projected score has many properties of a log-likelihood function. Finally, some examples are given to illustrate the theoretical results.
