A survey of permutation tests for censored survival data

The present paper surveys tests with censored sur-vival data for 2-and k-samples and for association by a framework which classifies them into complete or restric-ted permutation tests and into tests based on U-or Savage-scores. The formulae of the resulting twelve tests are briefly described for quick reference. Some of the tests have been applied frequently in the past as the tests by Mantel, Breslow or Gehan; others have been developed rather recently, partly by the author. The concluding discussion presents the results of a simulation study, clarifying similarities and differences of the restricted and complete permutation approach, and deals with rela-tive efficiencies of the two scoring systems.     

Top Ten Challenges for Understanding Gender and Aggression in Children: Why Can’t We All Just Get Along?

This essay identifies ten significant methodological challenges for understanding aggression and gender. In light of the recent explosion of research on indirect/relational/social aggression, it seems important to clarify gaps in our current understanding and to identify promising methods by which better answers might be found. The discussion begins with basic issues of definitions, contexts and subtypes, moves on to points concerning sampling and measures, and addresses whether current evidence warrants deciding that girls are as aggressive as boys. We conclude that although research has shown that the majority of girls' aggression takes indirect/relational/social forms, it is premature to conclude that boys do not also engage in these behaviors. We caution against assuming that physical and indirect/relational/social aggression are comparable in their developmental origins and consequences, and urge researchers to consider that fully understanding indirect/relational/social aggression might require different conceptual frameworks and research methods.     

结社自由简论

宪法性法律和国际人权条约承认和保护的结社自由，是个体基于不同的原因而与他人结成名称、规模、宗旨和目标等各不相同的组织的权利。文章从四个方面，即什么是结社自由、它有什么功能、法律如何对之进行保护以及结社自由与表达自由之间的关系，对结社自由进行了界定。     

吴中昆曲发展史考论

作为吴文化的结晶，昆曲自明代经魏良辅革新后，即以苏州为中心传播到南北各地，但始终以苏昆为正宗，形成了“四方歌者皆宗吴门”的局面。在昆曲的剧本创作和演艺方面，也以苏州派及吴中的昆班为上乘。特别是“虎丘中秋曲会”，更显示了昆曲发展中专业和业余相结合的深厚的群众基础。     

试论汉语比喻的心理基础及文化观照

比喻是对感知过程中产生的某种联想进行描述的一种语言艺术手法,＂联想＂是比喻的心理基础。比喻的结构构成及其功能实现,都需建立在类比联想的基础之上。这种联想的产生会受到人们所生活的文化背景的影响,因此比喻也是一种文化现象。从广阔的文化背景中观察分析汉语中的比喻,能更好地了解其文化特征。     

The behavior of estimated measures of association in small and moderate sample sizes for 2×3 tables

We consider the distributions of Goodman and Kruskal's G, Kendall's tau-b, and correlation coefficients rho and rho-s for sample sizes 10‘10’40 from 2×3 tables. The results are compared with asymptotic theory. It is found that the convergence of G to its asymptotic normal distribution is much slower than the convergence of the other measures to theirs, and that G is more likely to be significantly biased. However, the variances and biases of all four measures come close to their asymptotic values for quite moderate sample sizes.     

A Consumer Cooperative Association Specializing in Services for the Elderly

Summary

Over the past 10 years, a Japanese cooperative association named Fukushi Club Seikyo (FCS) has developed a unique, non-profit business specializing in services for the elderly. It aims to promote a reciprocal support system among neighborhood community members. FCS has successively organized its active members, mainly homemakers, into workers' collectives and successfully provided various life support services at a very small charge. Their human-touch service appears in sharp contrast to bureaucratic public services and profit-making private services. The civil initiative presented by FCS suggests a potential for a community-based social service system that may guarantee quality services without raising taxes and premiums for social insurance.     

A new special class of peb designs

A new class of partially efficiency-balanced designs is introduced from a practical point of view. This new design includes all equireplicated incomplete block designs available in literature as special cases. The fundamental properties of the design are clarified with relation to other block designs.     

On a paper by kageyama and mohan

Kageyama Mohan (1984) have presented three methods of constructing new incomplete block designs from balanced incomplete block designs, They raise questions about the designs which come from each of their methods, These questions are answered, Another series of group divisible designs is derived as a special case of their second method.     

浅析行业协会在构建和谐社会中的作用

和谐社会的构建必须充分调动一切积极因素,尤其要很好地发挥各类非政府组织的作用。行业协会作为非政府组织中的一支重要生力军,对和谐社会的构建必将发挥重要的积极作用,但我们也不可忽视作为自治组织的行业协会对构建和谐社会的一些负面作用。为此,需要政府、行业协会及企业三方共同努力,使行业协会在和谐社会构建中的积极作用得以充分发挥。
