维柯:发现"真正的荷马"

当笛卡儿理性主义宣称只有哲学才能真正认识传统,并视诗歌为无理性,主张废黜荷马的思潮盛行,维柯断言"真正的荷马"就是人类最初文明的创造者.寻找真正的荷马是维柯对传统的重新认识和评价,其价值在于维柯试图通过阐释荷马来沟通诗歌与哲学之间的鸿沟,为历史寻求确定的知识,而这正是寻找真正的荷马的人文主义内蕴.     

马克思主义中国化思想的源流

马克思主义中国化思想直接源于马克思、恩格斯、列宁等马克思主义经典作家的马克思主义民族化思想，但它的形成是“五四”新文化运动以后中国马克思主义者、中国共产党人长期艰辛探索的结果，党的七大对形成阶段的马克思主义中国化思想作了全面阐述。建国后，毛泽东提出了马克思主义与中国具体实际第二次结合的思想，这是对马克思主义中国化思想的重大发展。改革开放三十年来，我们党沿着邓小平所开创的中国特色社会主义道路继续不断地探索，使马克思主义与中国具体实际第二次结合的思想不断丰富和完善。党的十七大报告既是对马克思主义与中国具体实际第二次结合的思想、特别是改革开放三十年来马克思主义中国化思想发展成果的系统总结，又是新时期推进马克思主义中国化的庄严宣言。     

向塞林格致敬——塞林格与苏童少年小说比较

本文通过比较指出苏童因受到塞林格用少年视角,展现少年人的青春期困惑、独特心态的影响,以少年视角介入生命初状态,书写了生命初状态进入成熟现实那一瞬间的困惑、无奈、甚至是幻灭,共同揭示了人类文明相比纯洁的初状态被异化的悲哀。塞林格的少年视角有力的影响了苏童的同类写作,也在深得塞林格写作视角的精髓后,提升了苏童小说的人性关怀和生命景观呈现的力度。

伊斯兰世界女权主义及妇女运动

伊斯兰女权学说与妇女运动的产生,是伊斯兰世界现代社会发展的产物。以民族主义为依托,是早期伊斯兰女权思想产生与妇女运动发展的基本特点。在现代发展过程中,民族国家的建立,伊斯兰复兴运动的发展,以及现代家庭法的改革,皆影响到伊斯兰世界女权运动的发展态势,出现了世俗女权主义、伊斯兰女权主义与穆斯林女权主义的划分,这些不同的妇女组织分别以世俗的、宗教的或者民族的话语,从各自角度表达穆斯林妇女的权利要求,推动了伊斯兰世界穆斯林女性权利意识的发展。     

Semiparametric inference on partially linear single-index model

ABSTRACT

We consider semiparametric inference on the partially linearsingle-index model (PLSIM). The generalized likelihood ratio (GLR) test is proposed to examine whether or not a family of new semiparametric models fits adequately our given data in the PLSIM. A new GLR statistic is established to deal with the testing of the index parameter α₀ in the PLSIM. The newly proposed statistic is shown to asymptotically follow a χ²-distribution with the scale constant and the degrees of freedom being independent of the nuisance parameters or function. Some finite sample simulations and a real example are used to illustrate our proposed methodology.     

Penalized inverse probability weighted estimators for weighted rank regression with missing covariates

Abstract

In this article, we study the variable selection and estimation for linear regression models with missing covariates. The proposed estimation method is almost as efficient as the popular least-squares-based estimation method for normal random errors and empirically shown to be much more efficient and robust with respect to heavy tailed errors or outliers in the responses and covariates. To achieve sparsity, a variable selection procedure based on SCAD is proposed to conduct estimation and variable selection simultaneously. The procedure is shown to possess the oracle property. To deal with the covariates missing, we consider the inverse probability weighted estimators for the linear model when the selection probability is known or unknown. It is shown that the estimator by using estimated selection probability has a smaller asymptotic variance than that with true selection probability, thus is more efficient. Therefore, the important Horvitz-Thompson property is verified for penalized rank estimator with the covariates missing in the linear model. Some numerical examples are provided to demonstrate the performance of the estimators.     

Generalized varying-coefficient single-index model

In this paper, the generalized varying-coefficient single-index model is discussed based on penalized likelihood. All the unknown functions are fitted by penalized spline. The estimates of the unknown parameters and the unknown coefficient functions are obtained and the estimation approach is rapid and computationally stable. Under some mild conditions, the consistency and the asymptotic normality of these resulting estimators are given. Two simulation studies are carried out to illustrate the performance of the estimates. An application of the model to the Hong Kong environmental data further demonstrates the potential of the proposed modelling procedures.

Optimal asset allocation for participating contracts with mortality risk under minimum guarantee

Abstract

We investigate an optimal investment problem of participating insurance contracts with mortality risk under minimum guarantee. The insurer aims to maximize the expected utility of the terminal payoff. Due to its piecewise payoff structure, this optimization problem is a non-concave utility maximization problem. We adopt a concavification technique and a Lagrange dual method to solve the problem and derive the representations of the optimal wealth process and trading strategies. We also carry out some numerical analysis to show how the portfolio insurance constraint impacts the optimal terminal wealth.
