Designing two factor experiments for selecting interactions

This paper considers the problem of devising a single stage procedure for selecting the treatment combination associated with the largest interaction in a two-factor rfx× c experiment having independent normally distributed observations with common known variance. The intuitive procedure based on the best linear unbiased estimators of the population interactions is employed. Initially an indifference zone formulation is used; the problem of determining the least favorable configuration is reduced to a nonlinear programming problem with log concave objective function and a convex polytope as feasible region. A solution technique is introduced in the context of an illustrative example. The problem is also considered using a preferred population formulation; this approach requires a strengthened version of the indifference zone probability requirement. It is shown that the same sample size guarantees this requirement as does the earlier one.     

赛珍珠:一位文化边缘人

历时地看,作为美国第一位获得诺贝尔文学奖的女作家,赛珍珠显然没有受到学术界应有的重视。站在全球化语境下去认识赛珍珠,通过引入"文化边缘人"的概念去解读赛珍珠,我们可以找到赛珍珠及其作品被排斥在经典之外的原因。作为文化边缘人,赛珍珠站在了时代的前列,这也是在当今多元文化的语境下她被学术界"重新发现"的主要原因。从这个视角切入,我们可以更好地认识赛珍珠在当代世界文坛的文学地位。

Procedures for improving the mle for ordered binomial parameters

The problem is that of estimating the probabilities of m independent binomial random variables when their probabilities are known to be nondecreasing and the loss function is squared error. In the cases where the m.l.e. is inadmissible (essentially when the total number of trials is 7 or more) we present a method for modifying the m.l.e. to get a better estimator. The method requires a series of changes. At each step we alter the action taken by the m.l.e. on each of three, appropriately chosen, points in the sample space.     

A class of Shrunken estimators for normal mean

This paper presents a class of estimators for the mean of a normal population and determines the conditions on characterizing scalars under which the class of estimators uniformly dominates over the conventional sample mean according to the mean-square-error criterion.     

“S+V+R+O”双核谓词格框架研究

在“S +V +R +O”句式中 ,由于述语中心动词V价的不同、宾语的不同 ,补语R语义指向的不同 ,主语S、述语V、补语R、宾语O构成一个复杂的语义网络。弄清楚其中的语义网络 ,就可以着手建立“S +V +R +O”双核谓词格框架了。建立双核谓词格框架 ,可以促进对句子的理解 ,促进现代汉语格系统的建立     

从《父子之间》看早期生活对奈保尔文学创作的影响

《父子之间:家庭书信集》为我们研究奈保尔提供了最为真实可信的历史材料。通过分析这部家庭书信集,揭示出作家少年时代特立尼达生活的"文化悬挂",青年时代留学英伦经历的"文化祛根",以及父亲在文学上对儿子的影响;所有这些对于奈保尔精神气质和文学理念的初步形成,有着不可低估的作用。更重要的是,作家后来的"文化无根"状态,与这一时期的生活有密切关系。对这部书信集的研究,是全面了解奈保尔的必要起点。     

Comparing migrants to non-migrants: The case of Dutch migration to New Zealand

We analyse post-war Dutch migration to New Zealand. We document that history, reflect on analytical and econometric modelling and then combine a sample of Dutch migrants in New Zealand with a representative sample of Dutch in The Netherlands to estimate wage equations and the determinants of the migration decision. We use the results for ex post evaluation of the migration decision.Joop Hartog is Fellow of IZA (Bonn), CESifo (München), AIAS and Tinbergen Institute (Amsterdam). Work on this project was begun when Hartog was Erskine Visitor at the University of Canterbury, Christchurch New Zealand. Rainer Winkelmann is Fellow of CEPR and IZA (Bonn). This paper is produced as part of a CEPR research programme on European Migration from Economic Analysis to Policy Response, supported by a grant from the Commission of the European Communities under its Human Capital and Mobility Programme (no. ERBCHRXCT940515).It was presented at the European Society for Population Economics meetings in Bonn, June 2000.

关于赛珍珠研究的几个有待深入的问题

赛珍珠研究还有几个有待深入的问题:1 关于赛珍珠可不可以写入20世纪中国文学史的问题,可以从作家对自我身份的认定以及从作品的性质来决定。赛珍珠多次说自己"也是一个中国人",而她的作品大部分跟中国20世纪30年代的"乡土文学"有着紧密的血缘关系,因此她可以写入中国文学史。2 如何评价当年的西方传教活动及赛珍珠的传教士身份,总体上说,西方的传教活动对开启民智、加速中华民族的现代文明进程起到了一定的推动作用。赛珍珠是一位真诚善良、热心为中国人民服务的人。3 怎样评价赛珍珠的贡献,要看到她的"人桥"作用的特点本意在中美双方的"沟通"上,但重在对双方文化的匡正和建设上。4 要加强有关资料的搜集与整理。
