A class of distribution-free tests for two-way layout

In this article a class of distribution-free tests for the hypothesis of no row (treatment) effect in a two-way layout design, with several observations per cell, is proposed. The tests are based on U-statistics, constructed by considering minima of all possible subsamples of same size from each cell.The proposed class of tests is compared with the parametric test, Mack and Skillings test and Yate's test for two-way layout, in terms of Pitman ARE sense. It is seen that for the case of equal number of observations per cell, the proposed tests have better efficiency for exponential and uniform error distributions.     

Promoting Children's Welfare by Inter‐professional Practice and Learning in Social Work and Primary Care

Social work in the United Kingdom is an activity that benefits from, and often requires, co‐operation between different staff and across different professions. How this is to be achieved has been a central dilemma for practice and policy for many years. Primary care health services often play a key role. New policy and practice developments are designed to promote inter‐professional working with children, where research has shown significant problems in the community‐based health care of looked after children, children leaving care, and children at serious risk. There is, however, little evidence from research that supports current developments in inter‐professional practice; analysis of the particular nature of the inter‐professional problems is lacking, as are therefore the relevant inter‐professional solutions. A framework for better analysis, linked to developments in practice‐based research, one that would yield significant improvements for children's welfare, is presented here.

Maximal Invariant and Weakly Equivariant Estimators

Equivariant functions can be useful for constructing of maximal invariant statistic. In this article, we discuss construction of maximal invariants based on a given weakly equivariant function under some additional conditions. The theory easily extends to the case of two or more weakly equivariant functions. Also, we derive a maximal invariant statistic when the group contains a sharply transitive and a characteristic subgroup. Finally, we consider the independence of invariant and weakly equivariant functions under some special conditions.     

The power functions of the likelihood ratio tests for a simply ordered trend in normal means

Likelihood ratio tests for the homogeneity of k normal means with the alternative restricted by an increasing trend are considered as well as the likelihood ratio tests of the null hypothesis that the means satisfy the trend. While the work is primarily a survey of results concerning the power functions of these tests, the extensions of some results to the case of not necessarily equal sample sizes are presented. For the case of known or unknown population variances, exact expressions are given for the power functions for k=3,4, and approximations are discussed for larger k. The topics of consistency, bias and monotonicity of the power functions are included. Also, Bartholomew's conjectures concerning minimal and maximal powers are investigated, with results of a new numerical study given.     

试析反身宾语句的生成机制

反身宾语句生成有两个方面的因素，一是“身心二分”的“心支配身”认知框架，二是主观移情。反身宾语句有较强的描写性和事件伴随性，主要出现于文艺语体中。

The Role of the Social Worker in Long-Term Care

Abstract

Making use of a formulation by Rosalie Kane of the ingredients necessary to “a good life” for residents of homes for the aged and other long term care facilities, the role of the social worker in insuring the presence of these ingredients is discussed. Included is an analysis of the responsibilities and tasks of the social worker which must be carried and fulfilled in order that social workers make appropriate contributions to “the good life.”

20世纪50年代新诗对后期延安诗歌的“继承”

20世纪50年代新诗在“继承”后期延安诗歌创作资源过程中,呈现的内容是多样化的.除体制、队伍、生产与接受之外,风格与形式的相应延续,也在很大程度上影响到了50年代新诗的面貌.但无论就时代还是区域范围的差异,“继承”只是一个相对的概念.50年代新诗在自身发展过程中一直有自己的潜在内容,而其被“简约”的过程,正是历史延续过程中的复杂化部分.
