Pseudo‐likelihood ratio tests for semiparametric multivariate copula model selection

The authors propose pseudo‐likelihood ratio tests for selecting semiparametric multivariate copula models in which the marginal distributions are unspecified, but the copula function is parameterized and can be misspecified. For the comparison of two models, the tests differ depending on whether the two copulas are generalized nonnested or generalized nested. For more than two models, the procedure is built on the reality check test of White (2000). Unlike White (2000), however, the test statistic is automatically standardized for generalized nonnested models (with the benchmark) and ignores generalized nested models asymptotically. The authors illustrate their approach with American insurance claim data.     

单位犯罪成立范围的界定

单位犯罪历来为刑法学界所关注。随着新刑法典的颁布和实施,有关单位犯罪的热点问题发生了转移,其中的争议之一就是单位犯罪应在何种范围内成立。作为分析问题的两个不同视角,相关的领域界定和主观形态界定就成为不可或缺的话题。     

Testing circular symmetry

The author addresses the problem of testing circular data for reflective symmetry about an unknown central direction and proposes a simple omnibus test based on the sample second sine moment about an estimation of this direction. Under quite general conditions, for an underlying distribution which is reflectively symmetric, the large‐sample asymptotic distribution of the test statistic is standard normal. Randomization and bootstrap variants of the test are also introduced, and the operating characteristics of different versions of the test are investigated in a Monte Carlo study. The large‐sample and bootstrap versions of the test are applied in the analysis of two illustrative examples drawn from the circular statistics literature.     

宪法解释机关比较研究

各国宪法解释机关大体上分为三种模式 :即普通法院体系中的最高法院、独立的宪法法院和立法机关。其共同特点是宪法解释机关与承担违宪审查职责的宪法监督机关是同一个机关 ,并且基于一定的法理学基础。宪法解释需要一个最终的、权威的机关 ,但也离不开其他的机关为补充 ,这是各国宪法解释的共同特点。我国宪法规定全国人大常委会解释宪法 ,是指由全国人大常委会对宪法解释享有最终的、最后的解释权。在我国宪法解释的实践中 ,最高人民法院 ,全国人大常委会法制工作委员会 ,国务院 ,省一级人民代表大会工作机构对宪法解释的法案例 ,表明我国这些宪法解释机关的从属性、附属性与补充性。而最高人民法院在裁判案件中对宪法进行的解释的案例 ,正是宪法实施保障法理学与宪法解释本身的需要 ,与宪法规定的全国人大常委会解释宪法是一致的 ,并不矛盾与冲突     

Economic hardship in the family of origin and children's psychological well‐Being in adulthood

Past research consistently indicates that poverty and economic hardship have negative consequences for children. Few studies, however, have examined whether these consequences persist into adulthood. This study addresses this gap by assessing whether economic resources in the family of origin have long‐term effects on psychological well‐being in adulthood. Specifically, we test two processes—one involving interpersonal processes in the family of origin, and the other involving children's socioeconomic attainment—that may help to explain the link between early economic factors and later well‐being. Using 17‐year longitudinal data from two generations (N= 589), we find evidence that economic hardship in the family of origin predicts later adult well‐being through the parents’ marital relationship, the parent‐teen relationship, children's educational attainment, and children's earned income. Supplementary analyses suggest that economic hardship is particularly problematic when it is of long duration or when it occurs during adolescence.     

The deinstitutionalization of American marriage

This article argues that marriage has undergone a process of deinstitutionalization—a weakening of the social norms that define partners' behavior—over the past few decades. Examples are presented involving the increasing number and complexity of cohabiting unions and the emergence of same‐sex marriage. Two transitions in the meaning of marriage that occurred in the United States during the 20th century have created the social context for deinstitutionalization. The first transition, noted by Ernest Burgess, was from the institutional marriage to the companionate marriage. The second transition was to the individualized marriage in which the emphasis on personal choice and self‐development expanded. Although the practical importance of marriage has declined, its symbolic significance has remained high and may even have increased. It has become a marker of prestige and personal achievement. Examples of its symbolic significance are presented. The implications for the current state of marriage and its future direction are discussed.     

Exploring Nonnormative Coresidence in Urban China: Living With Wives’ Parents

We model histories between two cohorts of urban Chinese couples (N = 1,191) of a rarely studied living arrangement—coresidence with the wife's parents—using a dynamic life history analysis in contrast to previous cross‐sectional studies of coresidence. We examine patterns of entry into and exit from coresidence with the wife's parents, comparing the predictive power of modernization theory to the effect of demographic change and the resources and needs of each generation. Given China's well‐known patrilineal family system, we find a surprisingly high number of couples ever residing nonnormatively, and significant differences between cohorts in what determines the pattern of coresidence. Resources and needs that reflect conscious choices to coreside most strongly influence nonnormative coresidence. Its importance may increase as the children of the One‐Child Family Policy grow up and marry.     

Emotional harm and neglect: the legal response

This paper reports on a study of the extent to which child protection applications brought to the Melbourne Children's Court in Victoria, Australia, were based on emotional/psychological harm or neglect of a child and what factors were presented as evidence of harm or neglect. The study examined records of 208 court‐ordered pre‐trial conferences heard in the court between February and July 2002. What was found was that, although cases involving emotional abuse have increased in terms of child protection applications, they remain cases that are difficult to decide. While in 1998/9 emotional harm was a ground in 25.7% of child protection matters completed in the Family Division of the Children's Court of Victoria, legal decision‐makers are reluctant to make a finding of child abuse in these cases because there is less accuracy in the determination of emotional harm and negligible legal criteria available to guide decision‐making.

Reproducibility of clinical data I: continuous outcomes

Across a variety of clinical settings, repeated measurements on an individual, obtained under identical circumstances, often differ from one another. This implies the measurements lack perfect reproducibility. Topics related to reproducibility of clinical measurements are introduced in this paper. In this first of two parts, continuous outcomes are addressed. The intraclass correlation coefficient, ρ, has been the traditional coefficient of reproducibility for continuous outcomes. The importance of ρ regarding observations on an individual, and observations among populations, is outlined. Estimation and inferential procedures for ρ are reviewed and worked examples are provided. Copyright © 2004 John Wiley & Sons, Ltd.     

Restructuring Flexibility: Case Studies of Part‐Time Female Workers in Six Workplaces

The article is based on six workplace case studies within a local economy and investigates the reasons behind the different utilization of part‐time workers within these workplaces. The research examines the content and nature of part‐time work in these organizations and the experiences of the part‐time workforce. The findings suggest that we need to distinguish between three types of part‐time workers; core, peak and ancillary. It is argued that such distinctions capture the variegated utilization of part‐time workers and contribute to the debate concerning the integration or marginalization of part‐time staff within workplaces. Furthermore, workplace cultures are an important arena for contextualizing these discussions. It is contended that the different uses of part‐time workers can be explained by different sectoral and organizational contexts but that the nature of part‐time work is also influenced by existing social relations within the workplace, notably with respect to gender, class and age.
