《孟子字义疏证》对《孟子》的阐释和创新

戴震《孟子字义疏证》采用经学训诂的形式对义理内容进行建构,在学术思想史上产生了巨大影响。本文对戴震的义理旨趣、考据特征以及对《孟子》的创新阐释及其缺陷作了分析,认为其过度目的性阐释导致了《疏证》在接受方面的诸多困局。戴震义理学表面上对程朱理学持批判立场,但双方在动机、旨趣和义理内容的建构上不具同源性,戴震把程朱理学瑕疵当成程朱理学本身加以攻击,对原始儒意的理解并没有超越宋儒而进行。戴震对于《孟子》的把握仍有未达,但《疏证》所展现出来的批判精神却影响深远。     

试论老子的生态智慧及其现代启示

老子的生态哲学思想可以归纳为三个方面：“道生万物”物无贵贱的万物平等观、“道法自然”的生态规律观以及“自然无为”的生态实践观。它告诫我们在处理人与自然关系时应该改变传统的以人为中心、把自然看成人的依附物的观念,树立全面、协调、可持续的发展观,放弃为追求利益和效率最大化对自然进行随心所欲的改造的做法,加强对技术以及人的私心、贪心的道德约束,建立平等、和谐的生态环境。

Sieve Estimation of Time-Varying Panel Data Models With Latent Structures

We propose a heterogeneous time-varying panel data model with a latent group structure that allows the coefficients to vary over both individuals and time. We assume that the coefficients change smoothly over time and form different unobserved groups. When treated as smooth functions of time, the individual functional coefficients are heterogeneous across groups but homogeneous within a group. We propose a penalized-sieve-estimation-based classifier-Lasso (C-Lasso) procedure to identify the individuals’ membership and to estimate the group-specific functional coefficients in a single step. The classification exhibits the desirable property of uniform consistency. The C-Lasso estimators and their post-Lasso versions achieve the oracle property so that the group-specific functional coefficients can be estimated as well as if the individuals’ membership were known. Several extensions are discussed. Simulations demonstrate excellent finite sample performance of the approach in both classification and estimation. We apply our method to study the heterogeneous trending behavior of GDP per capita across 91 countries for the period 1960–2012 and find four latent groups.     

A Novel Method to Calculate Mean Survival Time for Time-to-Event Data

In the analysis of time-to-event data, restricted mean survival time has been well investigated in the literature and provided by many commercial software packages, while calculating mean survival time remains as a challenge due to censoring or insufficient follow-up time. Several researchers have proposed a hybrid estimator of mean survival based on the Kaplan–Meier curve with an extrapolated tail. However, this approach often leads to biased estimate due to poor estimate of the parameters in the extrapolated “tail” and the large variability associated with the tail of the Kaplan–Meier curve due to small set of patients at risk. Two key challenges in this approach are (1) where the extrapolation should start and (2) how to estimate the parameters for the extrapolated tail. The authors propose a novel approach to calculate mean survival time to address these two challenges. In the proposed approach, an algorithm is used to search if there are any time points where the hazard rates change significantly. The survival function is estimated by the Kaplan–Meier method prior to the last change point and approximated by an exponential function beyond the last change point. The parameter in the exponential function is estimated locally. Mean survival time is derived based on this survival function. The simulation and case studies demonstrated the superiority of the proposed approach.     

论审美的中介作用

关于审美与艺术的关系,中外美学史上历来存在政教中心论与审美中心论之争.但两者都没有给审美找到在艺术中的正确位置.确立审美在艺术中的地位的两条途径是其一,为了包容不是以"美"为主要描写对象的各种现代艺术,应该把"美的艺术"扩大到"审美的艺术",但"美的艺术"仍是艺术的主流.其二,为了纠正审美中心论忽视审美与艺术中的其他因素以及审美与艺术之外的其他社会因索的联系这一理论错误,必须以审美中介论取代审美中心论.     

Differences in Child Health Across Rural,Urban, and Slum Areas: Evidence From India

The developing world is rapidly urbanizing, but an understanding of how child health differs across urban and rural areas is lacking. We examine the association between area of residence and child health in India, focusing on composition and selection effects. Simple height-for-age averages show that rural Indian children have the poorest health and urban children have the best, with slum children in between. With wealth or observed health environment held constant, the urban height-for-age advantage disappears, and slum children fare significantly worse than their rural counterparts. Hence, differences in composition across areas mask a substantial negative association between living in slums and height-for-age. This association is more negative for girls than boys. Furthermore, a large number of girls are “missing” in slums; we argue that this implies that the negative association between living in slums and health is even stronger than our estimate. The missing girls also help explain why slum girls appear to have a substantially lower mortality than rural girls, whereas slum boys have a higher mortality risk than rural boys. We estimate that slum conditions (such as overcrowding and open sewers), which the survey does not adequately capture, are associated with 20 % to 37 % of slum children’s stunting risk.
