明朝服饰体现的等级差别

衣食住行，以衣为首。自古以来，服饰就是人们最为关注的生活必需品之一。所谓“衣披天下”、“衣锦还乡”都说明了中国服饰的历史悠久和业绩辉煌。在古代社会，统治阶级为巩固自身地位，把服饰的实用功能深化到更高级别的功能，服饰除能蔽体外，还被当做分贵贱、别等级的统治工具，成为等级社会鲜明的形象代言人。

论魏晋南朝的忠孝实践——以阳翟褚氏为例

忠孝取舍孰先孰后在魏晋南朝时期有一个演变的过程,弃忠从孝是当时社会的趋势和需要。阳翟褚氏在这一时期屡屡背信弃义违背＂忠＂的道德却又信守家族＂孝＂的传统,是当时忠孝实践观的集中代表。     

A hierarchy of lorenz curves based on the generalized tukey's lambda distribution

A hierarchy of Lorenz curves based on the generalized Tukey's Lambda distribution is proposed. Representations of the corresponding distribution and density function are also provided, together with popular inequality measures. Estimation methods are suggested. Finally, a comparison with other parametric families of Lorenz curves is established.     

An application of the integrated AHP-PGP model for performance measurement of supply chain management

The performance measurement problem has gained great attention in business and operations management literature. The first objective of this study is to determine the required performance measures and to develop a model for performance evaluation, based on these selected measures using analytical hierarchy process (AHP) methodology. The second objective is to explain how an integrated AHP-PGP (pre-emptive goal programming) model can be used in performance measurement while optimising the overall performance. An integration of AHP and multi-objective PGP is used to consider both quantitative and qualitative performance measures in optimising the overall performance of the system. The integrated model is presented with a real-world application using source data provided by a survey conducted in India. Findings demonstrate that the integrated AHP-PGP model can be useful to all supply chain industries in their day-to-day performance measurement decisions.     

Extreme probabilities for contingency tables under row and column independence with application to fisher's exact test

Theorerms are proved for the maxima and minima of IIR_i!/IIC_j!/T!II_yij ! over r× c contingcncy tables Y=(y_ij) with row sums R₁,…,R_r, column sums C₁,…,C_c, and grand total T. These results are imlplemented into the network algorithm of Mehta and Patel (1983) for computing the P-value of Fisher's exact test for unordered r×c contingency tables. The decrease in the amount of computing time can be substantial when the column sums are very different.     

Pmc-optimal nonparametric quantile estimator

According to Pitman's Measure of Closeness, if T₁and T₂are two estimators of a real parameter $[d], then T₁is better than T₂if Po[d]{\T₁-o[d] < \T₂-0[d]\} > 1/2 for all 0[d]. It may however happen that while T₁is better than T₂and T₂is better than T₃, T₃is better than T₁. Given q ? (0,1) and a sample X₁, X₂, ..., X_nfrom an unknown F ? F, an estimator T* = T*(X₁,X₂...X_n)of the q-th quantile of the distribution F is constructed such that P_F{\F(T*)-q\ <[d] \F(T)-q\} >[d] 1/2 for all F?F and for all T€T, where F is a nonparametric family of distributions and T is a class of estimators. It is shown that T* =X_j:n'for a suitably chosen jth order statistic.     

Experiences of Custody Evaluation: Perspectives of Young Adults Who Were the Subject of Family Court Proceedings as Children

ABSTRACT

Court-ordered custody evaluations are conducted primarily to assist courts in making decisions regarding the best interests of children in the context of parental disputes over custody and access. They also represent the most common means through which children's wishes in relation to custody and access are presented as evidence. This article reports on a qualitative research study of young adults' recollections of participating in custody evaluations ordered by the Family Court of Australia. In-depth interviews were conducted with 18 young adults, aged 18 to 26. Two major areas of inquiry are addressed in this article: (1) participants' recollections of interviews conducted by social workers and psychologists for the purpose of custody evaluation, and (2) their suggestions for ways in which professionals working with children in this context might make the process easier for children. Taken together, their experiences point to some useful principles for practice in this field.     

从《岛上夜娱》看斯蒂文森对其时代的超越与局限

斯蒂文森虽然生活在维多利亚时期，却不完全认同当时社会的一些主流价值观。在其《岛上夜娱》的三篇短篇小说中，他呈现了不一样的白人形象和土著女性形象，颠覆了传统白人的优越感。在探索殖民者与被殖民者关系基础上，揭示了白人文明对土著人的压迫。虽然小说在某些方面仍被禁锢在当时社会的意识形态中，但考虑到社会传统对作家思想的影响，小说意义深远。     

ON SOME OPTIMALITY PROPERTIES OF FISHER-RAO SCORE FUNCTION IN TESTING AND ESTIMATION

The score function is associated with some optimality features in statistical inference. This review article looks on the central role of the score in testing and estimation. The maximization of the power in testing and the quest for efficiency in estimation lead to score as a guiding principle. In hypothesis testing, the locally most powerful test statistic is the score test or a transformation of it. In estimation, the optimal estimating function is the score. The same link can be made in the case of nuisance parameters: the optimal test function should have maximum correlation with the score of the parameter of primary interest. We complement this result by showing that the same criterion should be satisfied in the estimation problem as well.
