思果的翻译观略述

思果是著名的散文家,又是杰出的翻译家。在其长期的翻译实践中,摸索出了别具一格的翻译理念,他主张要充分发挥中华文字的优势来从事翻译事业,并提出了两个重要的概念：（1）“抵抗式”翻译,即抵抗英文的“侵略”;（2）中国的中文,即用地道的中文来翻译。     

Cautionary Note about R 2

The coefficient of determination (R ²) is perhaps the single most extensively used measure of goodness of fit for regression models. It is also widely misused. The primary source of the problem is that except for linear models with an intercept term, the several alternative R ² statistics are not generally equivalent. This article discusses various considerations and potential pitfalls in using the R ²'s. Specific points are exemplified by means of empirical data. A new resistant statistic is also introduced.     

韦努蒂翻译理论:文化负载词汇的救星

文化负载词汇是民族文化的精髓,反映民族特色,体现民族语言文化艺术。韦努蒂理论是在反对主流文化占统治地位的背景下提出的,以其独特的翻译风格不仅进一步弥补了民族文化传承中的不足,尤其对文化负载词汇的翻译起了积极作用,而且其理论也引发了人们对文化领域中不同文化传播方式的进一步思考。同时,韦努蒂的思想也存在一定局限性,借鉴时应谨慎对待。     

Response shrinkage estimation in multinomial logit models

A shrinkage estimation method for multinomial logit models is developed. The proposed method is based on shrinking the responses for each category towards the underlying probabilities. The estimator is also used in combination with Pregibon's resistant fitting. The resulting estimator can also be used to control the over-estimation of Pregibon's resistant estimator. The proposed method handles not only the problem of separation in multinomial logit models but estimates also exist when the number of covariates is large relative to the sample size. Estimates exist even when the MLE does not exist. Estimates can be easily computed with all commonly used statistical packages supporting the fitting procedures with weights. Estimates are compared with the usual MLE and Firth's bias reduction technique in a simulation study and an application.     

鸭的大肠杆菌和沙门氏杆菌感染及药敏性测定

在九龙坡区白市驿、陶家、金风、含谷、走马镇的 2 5个养鸭场 (户 ) ,对鸭的大肠杆菌和沙门氏杆菌感染进行流行病学、临床症状、病理变化调查和实验室诊断 ,结果从病死鸭分离到Ⅰ—Ⅻ12株细菌 ,其中Ⅰ—Ⅵ菌株为大肠埃希氏菌 ,Ⅶ—Ⅻ菌株为沙门氏杆菌。药敏试验结果表明 :分离菌对头孢噻肟、头孢他啶的敏感率为 10 0 % ;阿米卡星、妥布霉素和奥格门丁 ,其敏感率为 75 % ;庆大霉素为 6 6 .6 7% ;而对红霉素、克拉霉素的耐药率达 10 0 % ;卡那霉素、链霉素和四环素的耐药率也达 83.33% ;且分离到的 12株菌都具有多重耐药 ,以Ⅱ菌株最强 ,在 2 6种抗菌药物中对 2 2种产生耐药性 ,耐药率达 84 .6 2 % ;次为Ⅵ和Ⅷ菌株 80 .77% (2 1/2 6 ) ;Ⅹ菌株为 6 5 .39% (17/2 6 ) ,Ⅻ菌株为 5 7.6 9% (15 /2 6 ) ,最低的Ⅲ和Ⅸ菌株也达 15 .39% (4/2 6 ) ,可见在这一地区鸭的大肠杆菌和沙门氏杆菌的多重耐药已相当普遍
