英汉翻译中的信息转换

翻译是因社会需要而产生的一种活动 ,在社会中扮演某种角色 ,因此译者及其译本在社会中也起着重要的作用。由于每个社会群体都有自己的共有知识 ,每一种语言都有其文化特点和表达习惯 ,因此译者在其翻译过程中就要考虑用适合目的语读者的语言把原文信息重新表达出来。重新表达不仅需要词法、句法方面的转换 ,还需要采取一些补偿措施对信息进行删减、重组、异化、归化等 ,这样才能把原文的信息适当地传递给目的语读者     

品牌管理的文化观思考及策略选择

表面上看 ,品牌就是产品的名称 ,但事实上 ,它更多地被注入特定的社会历史条件下人们的价值观念、理想寄托、风俗习惯、民族风情、历史传统等文化内涵。因此 ,在品牌管理中 ,必须重视和提升品牌中的文化内涵。如何以文化锻造品牌 ,挖掘品牌中的文化底蕴 ,恰当而有效地进行品牌的文化定位 ,从而提升品牌的价值 ,是现代品牌管理的核心内容之一 ,也是对品牌的深层次认识。     

An affine‐invariant multivariate sign test for cluster correlated data

The author presents a multivariate location model for cluster correlated observations. He proposes an affine‐invariant multivariate sign statistic for testing the value of the location parameter. His statistic is an adaptation of that proposed by Randles (2000). The author shows, under very mild conditions, that his test statistic is asymptotically distributed as a chi‐squared random variable under the null hypothesis. In particular, the test can be used for skewed populations. In the context of a general multivariate normal model, the author obtains values of his test's Pitman asymptotic efficiency relative to another test based on the overall average. He shows that there is an improvement in the relative performance of the new test as soon as intra‐cluster correlation is present Even in the univariate case, the new test can be very competitive for Gaussian data. Furthermore, the statistic is easy to compute, even for large dimensional data. The author shows through simulations that his test performs well compared to the average‐based test. He illustrates its use with real data.

A partial score test for difference among heterogeneous populations

In event time data analysis, comparisons between distributions are made by the logrank test. When the data appear to contain crossing hazards phenomena, nonparametric weighted logrank statistics are usually suggested to accommodate different-weighted functions to increase the power. However, the gain in power by imposing different weights has its limits since differences before and after the crossing point may balance each other out. In contrast to the weighted logrank tests, we propose a score-type statistic based on the semiparametric-, heteroscedastic-hazards regression model of Hsieh [2001. On heteroscedastic hazards regression models: theory and application. J. Roy. Statist. Soc. Ser. B 63, 63–79.], by which the nonproportionality is explicitly modeled. Our score test is based on estimating functions derived from partial likelihood under the heteroscedastic model considered herein. Simulation results show the benefit of modeling the heteroscedasticity and power of the proposed test to two classes of weighted logrank tests (including Fleming–Harrington's test and Moreau's locally most powerful test), a Renyi-type test, and the Breslow's test for acceleration. We also demonstrate the application of this test by analyzing actual data in clinical trials.

科学方法的发展与科学的发展:双向互动

科学研究作为人类认识自然界的一种活动,必须运用适当的方法,方法得当,事半功倍;方法不当,事倍功半。从科学史看,科学的发展和科学方法的发展是相互促进的:科学方法的发展有力地推动了科学的发展,科学的发展又反过来推动了科学方法的变革。因此,我们应当注重对科学和科学方法互动的研究,只有这样,才能更深刻地理解科学史。
