We consider the square contingency tables which arise when the same method of classification is applied twice. The hypothesis of marginal homogeneity is then relevant! and can be tested by various methods Models are discussed which contain marginal homogeneity as a special case. They include a class based on univariate and bivariate Dirichlet distributions. The question of ordered categories is briefly discussed. Applications are made to data on unaided distance vision.  相似文献

Several authors have conjectured, on the basis of their numerical work, that the maximum likelihood estimators of the shape and scale parameters of the Gamma distribution are positively biased. It is proved that their conjecture is always true.  相似文献

The case of selecting between a set of fixed models is considered. The true model is assumed to be contained in the set of proposed models and errors are taken to be normally distributed. A sequential procedure which yeilds probabilities of incorrect selections is proposed. The procedure is shown to have optimal properties and is extended to the estimated model case by a bootstrap procedure.  相似文献

In the real world situations, many time series are aggregates of two or more time series. An aggregation may take place due to an addition or the product or both of two or more time series. We are often interested in the study of the properties of aggregates which are, in turn, dependent on the properties of the constituent series. Motivated by this problem, the authors study in this paper the properties of models generated by the operator (Σ+II) on autoregressive-moving-average (ARMA) processes of orders (pi,qi), i = l→n . A few practical examples where such models have been used are given in the introduction and an illustrative numerical example is discussed at the end of the paper.  相似文献

Abstract

Most of the existing literature on Ashkenazi Orthodox Jewish lesbians focuses on sociological aspects, mainly the negative attitudes held by religious communities towards their sexual identity and the various problems that arise from these. Less attention has been paid to lesbians’ psychological coping mechanisms with the tensions between their two central identities: the religious and the sexual. Ashkenazi Orthodox lesbians find themselves in a complicated situation where they remain on the margins of both their “natural” communities: the religious one and the homosexual one. As a result, they feel rejected, isolated, and even punished by society. As believers, God is their ultimate refuge. But there are different conceptions of God, ranging from benevolent to persecutory, accepting or highly judgmental and punishing. This variance has not been considered in regard to the dual identity of Ashkenazi Orthodox lesbians. This article focuses on this neglected issue, examining Ashkenazi Orthodox lesbians’ conception of God and its relation to their managing the conflict between their apparently conflicting identities.  相似文献

ABSTRACT

In 2007, Korea implemented Child Development Accounts (CDAs) for institutionalised children in child welfare systems. Since then, the target group and a matching cap of CDAs in Korea have evolved. The target group expanded to include poor children receiving welfare, whereas the matching cap increased from KRW 30,000 (US$26.53) to KRW 40,000 (US$35.38), which is matched at a 1:1 rate. Despite the expansion, there is little empirical evidence examining the extent to which CDAs have influenced the life of participants. Using a content analysis method with a sample (N = 22), this study examines how CDAs have changed children’s mindsets, saving habits, education, future planning and sponsorship. The findings suggest that CDAs have multiple positive influences on children. This study concludes with policy implications for the inclusive and progressive development of CDAs in Korea.  相似文献

为了对我国营业转让的实践和立法有所帮助,文章运用比较分析的方法,对营业概念、营业转让的界定、营业转让中职工权益的保护以及营业转让平台的完善等问题进行了探讨.研究表明,由于我国法律未对营业转让进行明确规定,以致营业转让活动中存在着许多不规范、不合法的因素,阻碍了营业转让的顺利实现.指出我国立法机关应该借鉴国外法律,尽快制定全面、明确的营业转让制度,来规范、引导日益频繁的营业转让活动.  相似文献

This article focuses on multiple conditionalities in benefits and housing from the perspective of lone parents in Ireland. The Irish case echoes historical experiences elsewhere and is offered not as an exceptional or extreme case but as an in-depth single case study and a lens for comparison. Although contemporary forms and combinations of conditionalities are new to Ireland, the experience of multiple conditionalities in benefits and housing is not new. Hence, a historical perspective is used to examine contemporary multiple conditionalities in benefits and housing. In the past, conditional regimes for lone parents were justified in terms of moral reformation for first time mothers and avoiding moral contagion of mothers with subsequent pregnancies. In contemporary times, in the case of employment, lone parents are problematised as working part-time and “nesting” on in-work-benefits, and in the case of homelessness, lone parents who prioritise the security of tenure embedded in social housing are accused of “gaming” the system. While acknowledging ambiguities, the paper finds the overlap of welfare and housing discourses contribute, intentionally or unintentionally, to epistemological foundations or understandings of lone parents, shifting public perceptions, and framing them as “problems” to be solved. They simultaneously temper lone parents' expectations. Increased precarity and disempowerment is associated with dual conditionality, and ontological uncertainty is multiplied when experienced cumulatively across employment, social protection, and housing regimes in a context of generally poor public services and labour market precarity and in the historical context of stigmatisation. Nonetheless, lone parents demonstrate considerable agency.  相似文献
