起点即终点:从《白孔雀》到《恰特莱夫人的情人》

《白孔雀》与《恰特莱夫人的情人》分别是D.H.劳伦斯长篇小说创作的起点和终点。《白孔雀》中的乔治和洛茨理以及《恰特莱夫人的情人》中的恰特莱和梅勒斯分别映射出劳伦斯小说极具特色的主人翁;洛茨理和恰特莱表征了物欲横流的恶果以及人性与和谐性爱的失落;乔治最终的颓废是作者对工业文明的批判,而梅勒斯映射出作者对大自然的热爱、对人性复苏与和谐理想的渴望;女主角莱蒂的屈从和康妮最终的救赎映射出作者的女性观,其生活的树林成为劳伦斯希望的表征……这两部作品映射出劳伦斯人生探索的圆周式轨迹。     

张学良的爱国情怀

以翔实的史料论证了张学良将军是一位伟大的爱国者:他反对内战,维护国家的统一;在中华民族危亡的紧急关头,他毅然发动西安事变,联共抗日,为结束十年内战,促成第二次国共合作,实现全民族抗战做出历史性贡献;在漫长的幽禁岁月里,他虽身处逆境,但爱国初衷不变,仍关心抗战;张学良晚年心系祖国统一和富强,情萦中华民族的繁荣昌盛。     

张学良与爱国主义教育

指出张学良作为一位伟大的爱国者,不仅自己践行其爱国思想,而且高度重视爱国主义教育。探讨了张学良重视爱国主义教育的思想基础,对青年学生进行爱国主义教育的内容及其形式。运用史料论证了教育兴国思想是张学良重视爱国主义教育的思想基础;提出张学良爱国主义教育思想具有鲜明的时代特点;张学良重视校园文化建设,以此激发青年学生的爱国热情。尤其强调了张学良在培育东北大学爱国主义光荣传统中的重要作用。     

张学良口述历史中的历史文化观

张学良自幼接受的是中国传统文化教育,到青年时开始接触西方文化,他自己认为受西方文化影响较大。晚年在接受访者访问时,他谈到了传统文化,认为是宋儒理学阻碍了中国科学技术的发展。在谈到人生的意义时,强调人要有理想信仰,没有理想信仰就没有根。在谈到做人做事时,他说要尽力想到他人,要凭良心。在谈到他追随蒋介石"剿共"时,他说国民党不能战胜共产党的根本原因,在于民心的向背。在谈到他在囚禁期间研究明史问题时,他说是想通过研究明清历史,探索中国由盛转衰的原因。     

“甲型H1N1”流感防控中的公共卫生伦理难题

今年3月全球暴发“甲型H1N1”流感疫情,我国政府高度重视“甲型H1N1”流感的应对工作。在“甲型H1N1”流感防控中,在公共卫生伦理原则之间出现了相互冲突的伦理难题。只有遵循公共卫生伦理学中的四大基本原则：效用性原则、尊重原则、共济原则、相称性原则,才能够解决目前出现的难题。解决这些难题对于公共卫生机构和工作人员在应对的行动上有着重大的意义。     

Bayesian model selection for D‐vine pair‐copula constructions

In recent years analyses of dependence structures using copulas have become more popular than the standard correlation analysis. Starting from Aas et al. ( 2009 ) regular vine pair‐copula constructions (PCCs) are considered the most flexible class of multivariate copulas. PCCs are involved objects but (conditional) independence present in data can simplify and reduce them significantly. In this paper the authors detect (conditional) independence in a particular vine PCC model based on bivariate t copulas by deriving and implementing a reversible jump Markov chain Monte Carlo algorithm. However, the methodology is general and can be extended to any regular vine PCC and to all known bivariate copula families. The proposed approach considers model selection and estimation problems for PCCs simultaneously. The effectiveness of the developed algorithm is shown in simulations and its usefulness is illustrated in two real data applications.

On the Ghoudi,Khoudraji, and Rivest test for extreme‐value dependence

Ghoudi, Khoudraji & Rivest [The Canadian Journal of Statistics 1998;26:187–197] showed how to test whether the dependence structure of a pair of continuous random variables is characterized by an extreme‐value copula. The test is based on a U‐statistic whose finite‐ and large‐sample variance are determined by the present authors. They propose estimates of this variance which they compare to the jackknife estimate of Ghoudi, Khoudraji & Rivest ( 1998 ) through simulations. They study the finite‐sample and asymptotic power of the test under various alternatives. They illustrate their approach using financial and geological data.

A NONPARAMETRIC TEST OF SYMMETRY VERSUS ASYMMETRY FOR RANKED-SET SAMPLES

This paper introduces a nonparametric test of symmetry for ranked-set samples to test the asymmetry of the underlying distribution. The test statistic is constructed from the Cramér-von Mises distance function which measures the distance between two probability models. The null distribution of the test statistic is established by constructing symmetric bootstrap samples from a given ranked-set sample. It is shown that the type I error probabilities are stable across all practical symmetric distributions and the test has high power for asymmetric distributions.     

Inferences on the coefficient of variation of an inverse gaussian distribution

The likelihood ratio test for a characteristic parameter of the inverse Gaussian distribution is derived. The parameter of interest characterizes the coefficient of variation, the skewness and the kurtosis of the distribution. The distribution of the test statistic is presented in a simplified form. Useful quanfiles of the distribution are given. Methods for constructing confidence bounds for the parameter, including Bayes highest posterior density intervals, are considered.     

含控制因子的R/S分析的H参数估计及应用

R/S分析法是揭示金融时间序列长记忆性的主要方法之一。针对经典R/S与修正R/S分析法之不足,对R/S分析法进行改进,设计含控制因子的R/S统计量,并应用蒙特卡洛模拟说明改进的方法比经典R/S与修正R/S分析法在估计H指数上的有效性。运用新方法对上证综合指数和深圳成分指数收益率序列的长记忆性与两市的平均非周期循环长度进行实证分析,研究表明：沪、深股市的收益率序列都具有长记忆性,但是沪市的收益率序列不存在明显的平均非周期循环长度,而深市的收益率序列则存在一个大约308天的平均非周期循环长度。
