Inferences concerning interpersonal choices given anonymously

It may be difficult or impossible to make a reliable empirical investigation of an unknown network of interpersonal choices or contacts if these are in some respect sensitive for the individuals involved. We consider how choice data given anonymously can be used to reveal various features of the network. Using tools from statistical decision theory and information theory we can determine risks and capacities of disclosing choice data, the graph structure of choice data and its numbers of loops and mutuals. We give some general results, illustrate the combinatorial complexity of the problem and comment upon the computational difficulties.     

Optimal estimation of a finite population mean under generalized random permutation models

Employing certain generalized random permutation models and a general class of linear estimators of a finite population mean, it is shown that many of the conventional estimators are “optimal” in the sense of minimum average mean square error. Simple proofs are provided by using a well-known theorem on UMV estimation. The results also cover certain simple response error situations.     

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.     

Controlling health care costs: An evaluation of strategies

There has been much discussion about the factors underlying inflation in the health care sector and the means to moderate increases in health expenditures. This paper identifies various costcontainment strategies and synthesizes research findings that may be helpful in evaluating their effectiveness. The review demonstrates the complexity of the issues and relationships that must be confronted and understood in cost containment. The delivery system is shown to be not well-suited to improving efficiency and restraining health care expenditure. Any single strategy, whether it involves restructuring the market or more direct regulation, cannot in itself accomplish the combination of expenditure control and adequacy of services that is socially desirable. A number of mutually reinforcing strategies are required. Finally, more empirical and analytical information on incentives, provider and regulatory decisionmaking, costs of regulation, and the dynamics of negotiation, is essential for the design of an effective costcontainment program.     

《红楼梦》“大荒山”并非长白山——与陈景河先生商榷

《红楼梦》中的“大荒山”并非陈景河先生所误引的《山海经·大荒西经》中“大荒山”,也与长白山无关,乃“荒唐言”耳。不能认为《红楼梦》主旨是写满族的兴衰史,表现的是中原腐朽文化和关外满族原始素朴文化的冲突等等。红学研究必须讲究科学的“方法论”。     

“A是A，B是B”句联的内部构造和外部构成

"A是A,B是B"句联内部各小句一般都是有序排列且有较高的一致性.各小句的前段可以是名词性的,也可以是谓词性的;后段大都重复前段,极少的时候略有变化;中段有条件地容纳状语.各小句的重音分布是"中-轻-重",这与单用的"A是A"小句明显不同."A是A,B是B"句联在结构上是弱自由句联,在表意上不自足.常在小句中作成分,或在复句中与紧邻的其他小句或句联形成各种关系,少数时候也可以单独构成复句.

论李焘对《王安石日录》的取舍

以往学界多认为李焘在《续资治通鉴长编》中采录《王安石日录》入正文,是不因人废言的良史作派,但这只是注意了李焘用《日录》订正史实的一面,而在具体到事关新法是非以及针贬变法方面的深刻用意却很少注意。实际上李焘是用王安石自己的记录来否定变法。     

梦幻如织缘情深－－《红楼梦》梦境描写综论

"情",指人的各种感情欲望,是<红楼梦>中揭示得最为深透,表现得最为成功的重要内容.梦因情而生,曹雪芹在书中写了大小数十种梦幻,说到底都是为表现"情"服务的.情切切,情未了.梦是情的派生物,作者对书中人物的梦幻写得细腻、逼真、传神,变化多端,熠熠生辉.所揭示的情更是浓烈、厚重、含蓄、深沉,丰富多采,耐人寻味.情与梦浑然一体,梦与情对表现人物揭示主题可谓双峰对峙,相得益彰.     

严羽和戴复古身世行迹诸问题考——对《严羽评传》的几点商榷性意见

严羽和戴复古订交的时间在绍定五年 (12 32 )而非嘉定十四年 (12 2 1) ;严羽避乱返乡时间在绍定四年而非元年 ;严羽的《平寇颂》写于端平元年 (12 34 )五月之后而非绍定三年间 ;戴复古布衣一生 ,并未任过邵武军学教授
