A Note on Comparison of (Non) Linear Estimators Using Pitman's Measure of Closeness

We present some sufficient and necessary conditions under which some linear (or nonlinear) estimators (see Sections 2 and 3) dominate (are better than) others in the sense of PMC. Its applications in linear regressions are also discussed. Furthermore, we obtain results about the eigenvalues of two matrices, which seem to be hard to be prove through pure matrix theory.     

Shrinkage Estimators for Prediction Out-of-Sample: Conditional Performance

We find that, in a linear model, the James–Stein estimator, which dominates the maximum-likelihood estimator in terms of its in-sample prediction error, can perform poorly compared to the maximum-likelihood estimator in out-of-sample prediction. We give a detailed analysis of this phenomenon and discuss its implications. When evaluating the predictive performance of estimators, we treat the regressor matrix in the training data as fixed, i.e., we condition on the design variables. Our findings contrast those obtained by Baranchik (1973 Baranchik , A. J. ( 1973 ). Inadmissibility of maximum likelihood estimators in some multiple regression problems with three or more independent variables . Ann. Statist. 1 ( 2 ): 312 – 321 .[Crossref], [Web of Science ®] , [Google Scholar]) and, more recently, by Dicker (2012 Dicker , L. ( 2012 ). Dense signals, linear estimators, and out-of-sample prediction for high-dimensional linear models. arXiv:1102.2952 [math.ST].  [Google Scholar]) in an unconditional performance evaluation.     

亨利·詹姆斯《悲惨的缪斯》中的单一神话演变模式

运用诺斯罗普·弗莱的神话演变理论对亨利·詹姆斯的中期作品《悲惨的缪斯》进行了探讨,发现其故事情节的发展与单一神话的演变过程相吻合,《悲惨的缪斯》中神话与唯美主义的完美结合体现了詹姆斯对唯美主义的探索,这是詹姆斯在文学创作上的又一贡献。     

詹姆士对休谟问题的解决

在哲学史上,休谟问题的提出与诸多的解决尝试,极大地推动了对知识的本性和科学方法论的深入研究.詹姆士改造了传统经验主义,"彻底的经验主义"消解了休谟问题,"实用主义的方法"解决了这一问题.     

布鲁斯与破碎的梦想——解读詹姆斯·琼斯的《从这里到永恒》

美国小说家詹姆斯·琼斯的代表作《从这里到永恒》（1951）描写了二战爆发前驻守夏威夷的美国士兵的军旅生活。在小说中,布鲁斯音乐不仅作为展示士兵业余爱好和娱乐生活的一种方式在小说中数次出现,而且成为一种特殊的象征符号预示着人物命运的走向,并推动着故事情节的发展。本文试图以布鲁斯为切入点,将其与小说所反映的美国20世纪三四十年代广阔的社会背景联系起来,分析布鲁斯承载的文化意义的流变在这一时期的具体表现,再将其与小说主题相结合,进而探讨布鲁斯音乐与小说文本的互动。     

论《都柏林人》中女性的“角色作为”

詹姆斯·乔伊斯在其短篇小说成套故事集《都柏林人》中集中探讨了都柏林社会的精神瘫痪。这种瘫痪表现为“力量的衰退、意志的萎缩及心灵的死亡”。从女性主义角度来看,这种瘫痪在本质上是父权社会的瘫痪,并通过《都柏林人》中女性的“角色作为”得以成功体现。     

谈詹姆斯·乔伊斯书信的价值

詹姆斯·乔伊斯是20世纪最重要,最有影响的作家之一.他没有自传和日记传世,但保存下来的书信从字数上讲,几乎赶得上他的小说总量,是全面展示乔伊斯的生平和作品的第一手文字材料,若要全面研究乔伊斯不可不读他的书信.     

An interview with George Hallett

The distinguished South African photographer George Hallett speaks about his childhood, schooling, career in photography, exile in Europe and return to South Africa. Born in District Six and raised in Hout Bay, Hallett was introduced to the world of politics, literature and art by the novelist Richard Rive, who was his high school English teacher, and by the poet James Matthews and artist Peter Clarke, who became friends, as well as mentors. Hallett began his photographic career in Cape Town, but, struggling under the restrictions of life under apartheid, soon left for London. In Britain and, later, France and the Netherlands, he established himself as a leading photojournalist and fine art photographer. After brief stays in the United States and Zimbabwe, he returned to South Africa to photograph the 1994 elections for the African National Congress.     

从《论语》两个英译本比较看翻译的文化转向

文化翻译理论在文化层面对翻译所作的反思可以解释《论语》不同时期英译本的巨大差异,在这一理论的指导下对《论语》理雅各译本和安乐哲译本进行对比研究,通过分析认为理雅各译本是基于文化中心主义基础上的语言翻译代表作品,而安乐哲译本是基于多元化理论的文化翻译典范。安乐哲译本的存在,证明了文化翻译不仅是一种构想,还是一种事实,因此有可能从安乐哲译本中寻求到文化翻译理论在方法论上的突破。
