《道连·格雷的画像》中的唯美主义艺术

王尔德的《道连.格雷的画像》是一部唯美主义的小说。作品着意表现王尔德的艺术战胜生活,艺术和美是永恒无上的等唯美主义主题,但仍无法摆脱艺术反映自然与生活的自然法则的矛盾与困扰。王尔德提出了生活与自然都反映艺术的观点,虽有一定的局限性,但在他所处的维多利亚时期,也显示出他对艺术的纯洁性与独立性的捍卫。     

基于Gray—Markov模型的城乡建设用地规模预测——以张掖市为例

科学合理的用地需求预测方法是土地利用总体规划能否制定科学合理目标的关键。选取在形态上呈相对聚集、面状分布的城乡建设用地为预测对象,将Gray—Markov模型引入到城乡建设用地规模预测中来,并以甘肃省张掖市为例进行了实证研究。结果表明：与其他预测模型对比,Gray—Markov模型模拟和预测精度更高,能够为土地利用总体规划提供可靠保证。     

A technique for generating Gray codes

It is often desirable to use Gray codes with properties different from those of the standard binary reflected code. Previously, only short codes (32- to 256-element) could be systematically generated or found with a given set of properties. This paper describes a technique where long codes (65000-element or longer) as well as short codes can systematically be generated with desired properties. The technique is described and demostrated by generating codes of various lenght with the desired property of equal column change counts. Several examples of the use of the technique for generating codes with other desired properties are outlined.     

基于趋势外推模型和灰色系统模型的深圳保费收入总量预测

全国及各地区正在开展保险业＂十二五＂规划工作,保费收入总量是常用的指标之一。本文分别利用趋势外推模型和灰色系统模型对深圳保费收入总量进行预测,并比较两种模型的拟合精度,得出2010-2015年深圳保费收入总量预测结果,并提出了实现目标的建议,希望能为保险业预测工作提供一些参考方法。

Planning and analyzing clinical trials with competing risks: Recommendations for choosing appropriate statistical methodology

In the analysis of time‐to‐event data, competing risks occur when multiple event types are possible, and the occurrence of a competing event precludes the occurrence of the event of interest. In this situation, statistical methods that ignore competing risks can result in biased inference regarding the event of interest. We review the mechanisms that lead to bias and describe several statistical methods that have been proposed to avoid bias by formally accounting for competing risks in the analyses of the event of interest. Through simulation, we illustrate that Gray's test should be used in lieu of the logrank test for nonparametric hypothesis testing. We also compare the two most popular models for semiparametric modelling: the cause‐specific hazards (CSH) model and Fine‐Gray (F‐G) model. We explain how to interpret estimates obtained from each model and identify conditions under which the estimates of the hazard ratio and subhazard ratio differ numerically. Finally, we evaluate several model diagnostic methods with respect to their sensitivity to detect lack of fit when the CSH model holds, but the F‐G model is misspecified and vice versa. Our results illustrate that adequacy of model fit can strongly impact the validity of statistical inference. We recommend analysts incorporate a model diagnostic procedure and contingency to explore other appropriate models when designing trials in which competing risks are anticipated.     

《道连·葛雷的画像》：自我建构的诉求

拉康关于自我建构的精神分析理论扩展了文学批评的视野。王尔德的小说《道连·葛雷的画像》较好地体现了自我建构的主题：主人公道连自我认同的失真和俄狄浦斯情结过渡的失败导致了他无法确立主体性,死亡成为在想象界与象征界间徘徊不定的他之最终解脱;作者王尔德采用自画像的原理创作该小说,以他者的形式呈现自己,借此进行另类的自我建构。道连与王尔德安身立命之根本都是在探寻“我”之真相。     

从《道连·格雷画像》看王尔德的文学道德观

王尔德的《道连.格雷画像》既揭露和批判了英国维多利亚时代资产阶级上流社会道德的堕落,又对人们进行了严肃的道德教育;而他提出的“艺术不应受道德的约束”,是他反叛资产阶级时代道德的策略武器。更难能可贵的是,王尔德明知该小说要遭到非议,但他却冒着巨大的风险,将小说展示给人们。他是一位反叛资产阶级上流社会的斗士。     

灰色信息系统中的优势粗糙集模型

文章将一种新的优势关系引入到区间集灰色信息系统中,定义了对象灰度与对象确定度、整体灰度与整体确定度等概念,建立了基于优势关系的粗糙集模型,由此得出一系列相关性质与定理,最后用一实例进行了说明。     

奥斯卡·王尔德《道连·格雷的画像》中的东方想象

王尔德是维多利亚时期著名的作家,受东方文化影响很深,他的唯一的一部长篇小说《道连.格雷的画像》里面充满了对东方不同国度的想象,比如把中国和日本当作他的审美乌托邦,把印度和澳大利亚当作淘金和罪犯的天堂,中东等国家充满异域情调,犹太人依然被鄙视和嘲讽。这些想象或者是为了批判当时的实用和功利主义,或者是为了彰显宗主国文化的优越性,让作品充满东方浪漫异域情调的同时,也让我们了解了作为宗主国文化的对立面＂他者＂的东方是如何被审视的。
