试论汉末魏晋辞赋之“向内转”

“向内转”既是汉末魏晋文学总貌的新质素,也是该时期辞赋发展的基本趋势。该趋势在东汉后期已见先绪,在辞赋价值理论以及表现领域均有体现。情感化与玄理化成为汉末魏晋辞赋“向内转”的两个具体向度。汉末魏晋辞赋的“向内转”,继承楚骚传统,创造了一片有别于汉代辞赋追求外在世界的审美新天地。     

我国野生动物外来物种入侵的法律应对——兼谈对环境法“调整论”反思的反思

为有效应对野生动物外来物种入侵问题,我国应当借鉴美、日等国家的有益经验,及时修改《野生动物保护法》等立法,健全完善由外来物种的分类管理、风险评估、引进和放生许可、监测预警、应急反应等组成的制度体系。同时,还应当修改《侵权责任法》,将生态破坏侵权纳入统一的环境侵权责任制度;修改《刑法》,创设破坏生态罪的新罪名。此外,还应推进行政监管体制改革,成立专司生态保育工作的生态部,并在其下设立生物多样性管理局,实现对生物入侵应对事宜的统一监管。从理论上看,研究应对外来物种入侵的法律调整机理,不仅有助于理解关于环境法可以调整“人-自然”关系之“调整论”的可贵之处,还有利于揭示“自然体权利论”和“非人类中心主义”等极端观点的谬误所在,进而修正和完善环境法“调整论”。     

副文本与翻译研究——从序跋角度窥探小说翻译

学界从各个方面对小说的成功译介进行了探讨,但是鲜有学者从副文本翻译角度探讨其对小说译介的推动作用。本文从序跋角度探讨副文本在小说翻译中的阐释性功能,运用描述性研究方法,说明序跋在小说翻译中的作用。诸多例证表明,译者对原作中副文本的翻译为读者提供了了解作者、作品、译者翻译目的和翻译思想的捷径。

An Extended Projection Data Depth and Its Applications to Discrimination

This article investigates the possible use of our newly defined extended projection depth (abbreviated to EPD) in nonparametric discriminant analysis. We propose a robust nonparametric classifier, which relies on the intuitively simple notion of EPD. The EPD-based classifier assigns an observation to the population with respect to which it has the maximum EPD. Asymptotic properties of misclassification rates and robust properties of EPD-based classifier are discussed. A few simulated data sets are used to compare the performance of EPD-based classifier with Fisher's linear discriminant rule, quadratic discriminant rule, and PD-based classifier. It is also found that when the underlying distributions are elliptically symmetric, EPD-based classifier is asymptotically equivalent to the optimal Bayes classifier.     

Fundamental Equations of BLUE and BLUP in the Multivariate Linear Model with Applications

Ordinary least squares estimator (OLSE), best linear unbiased estimator (BLUE), and best linear unbiased predictor (BLUP) in the general linear model with new observations are generalized to the general multivariate linear model. The fundamental equations of BLUE and BLUP in the multivariate linear model are derived by two methods, including the vectorization method and projection method. By using the matrix rank method, some new results of linear BLUE-sufficiency, linear BLUP-sufficiency, and the equality of OLSE, BLUE, and BLUP are given in the multivariate linear model.     

Consistency and Normality of M-Estimators in Partly Linear Models with Stochastic Adapted Errors

The robust M-estimators for the partly linear model under stochastic adapted errors are considered. It is shown that the M-estimator of parameter is asymptotically normal and the M-estimator of the nonparametric function achieves the optimal rate of convergence for nonparametric regression. Some known results are improved and generalized. Some simulations and a real data example are conducted to illustrate the proposed method.     

Some Theoretical Comparisons of Negative Binomial and Zero-Inflated Poisson Distributions

In this article, we compare the zero-inflated Poisson (ZIP) and negative binomial (NB) distributions based on three most important criteria: the probability of zero, the mean value, and the variance. Our results show that with same mean value and variance, the ZIP distribution always has a larger probability of zeros; with same mean value and probability of zeros, the NB distribution always has a larger variance; and with same variance and probability of zeros, the ZIP distribution always has a larger mean value. We also study the properties of Vuong test in model selection in three cases by simulations.
