Child custody issues and co‐occurrence of intimate partner violence and child maltreatment: controversies and points of agreement amongst practitioners

The situation of families undergoing separation in a context of co‐occurrence of intimate partner violence (IPV) and child maltreatment raises certain issues related to child custody. The results presented in this paper were collected and analysed within the framework of a qualitative study aiming to identify the principal points of agreement and the main controversies amongst practitioners in several different types of organizations. Focus groups were held with a total of 43 practitioners from six different settings concerned with child custody in cases of co‐occurrence of IPV and child maltreatment. Although they agreed on the importance of ensuring the safety of victims of violence, their views diverged on three points: (1) the importance of preserving the father–child relationship; (2) collaboration between voluntary organizations and semi‐voluntary or legal agencies; and (3) consideration of cultural differences.     

抗战时期“近卫声明”的来龙去脉

1938年的三次“近卫声明”,都是日本政府为找到一个代表中国的谈判对手达到其侵略的目标而发布的。第一次近卫声明打开了诱降的大门,第二次、第三次近卫声明则是在日本大规模侵华军事进攻告一段落和汪精卫暗通日本的情况下发布的,完全体现了政治谋略为主、军事进攻为辅的方针,目的在于从政治上瓦解国民政府。三次近卫声明之中,以第二次近卫声明影响最为巨大而深远。     

Cox模型和寿险退保研究中的比例危险性

利用生存分析研究寿险退保问题是一个很好的工具，因为可以将寿险保单的持续期（persistency duration）视为生存期长，而将保单的退保或失效看作一个“保单生命”的结束，这其中的保单退保或失效就成为生存研究的目标事件。而导致保单失效的因素会有很多，只有通过利用Cox比例危险模型拟合寿险退保数据以分析影响客户退保的原因，并在对Cox模型的比例危险假设进行检验时，发现部分影响因素并不遵守此前提条件，从而推理得到这些影响因素在不同的时间段对客户退保的影响方式不同。也就是说，其影响有短期效应和长期效应之分。     

One of us? Reaction formation and inclusion as a strategy in the ethnic state

Many states question how to manage burgeoning migration. This is particularly problematic for ethnic states whose foundation myths imagine the state as the home for the nation. In this paper, we argue that ethnic states engage a type of defense mechanism, ‘reaction formation’, as part of migration policy to distract attention from threats to the claimed ethnic homogeneity that undergirds the reason for the state's existence. Using Israel as a case of a planned ethnic state, we show how a state develops a spectrum of membership models to incorporate ‘others’ into the nation-state. We suggest that Israel could conceivably devise some arrangement to incorporate the several hundred thousand labor migrants currently resident there. We argue that the state is reluctant to recognize these migrants as ‘Israeli’ because to do so would reveal a hidden truth: Israel may be becoming more Israeli than Jewish and, thus, the recognition of labor migrants and their children provokes questions about Israel's very reason for existence, that is, being a Jewish state.     

Between Neo-liberalism and Neo-indigenismo: Reconstructing National Identity in Mexico

Heightened integration with the US coupled with the rise of an indigenous movement have challenged and strained long-held images regarding the US and the indigenous within Mexico. As a result, Mexico finds itself facing the difficult task of re-evaluating and reconstructing its national identity. This paper explores the traditional images of the US and the Indian shaping national identity in Mexico and the challenges posed today by neo-liberalism and neo-indigenismo. It sets out a range of current issues, explores the linkages and contradictions, and examines the state of national reform. Fundamentally, the paper strives to raise important theoretical questions and hence set the stage for further research into these issues.     

The rise of militant Bretonité

The Breton movement in France grew increasingly militant in the late twentieth century, in part due to the French government. After its official and unofficial repression of Bretons ended in the mid-twentieth century, France never developed a consistent policy to deal with Breton culture. At the same time, the Bretons themselves changed their political outlook. The rise of militant Bretonité resulted from a new belief among the activists that their survival depended on government intervention. This change led to a shift in Breton politics from the right to the left, and an overall change in the movement itself.

Performing armchair roundoff analyses of statistical algorithms

Numerical stability is but one of many desirable properties which should be considered when designing statistical software. However, rigorous roundoff analysis is rarely done because it seems not worth the price; the influence of rounding error is usually of secondary importance, and the analysis is thought to be beyond the reach of all but a few specialists. This note discusses the role of roundoff analysis in the design of a statistical program and shows that new techniques sometimes make assessment of the effect of rounding errors no more difficult than the verification of other program properties.     

Indexing the Federal Tax System: A Cost-of-Living Approach

In this article, we analyze the indexation of federal taxes, using an approach based on cost-of-living measurement. We use our Tax and Price Index methodology and data base to study an indexed system historically, comparing indexation with the Consumer Price Index (CPI) to actual tax policy, a tax system with constant parameters, and an “exact” indexing scheme. We reach three main conclusions: (a) The sequence of tax reductions implemented between 1967 and 1985 have fallen short of mimicking indexation, (b) wealthier households would have benefited relatively more than lower-income households from indexation, and (c) CPI indexation would not have completely eliminated bracket creep.     

A family of estimators of population variance in two-occasion rotation patterns

Abstract

In this article, we have considered the problem of estimation of population variance on current (second) occasion in two occasion successive (rotation) sampling. A class of estimators of population variance has been proposed and its asymptotic properties have been discussed. The proposed class of estimators is compared with the sample variance estimator when there is no matching from the previous occasion and the Singh et al. (2013) estimator. Optimum replacement policy is discussed. It has been shown that the suggested estimator is more efficient than the Singh et al. (2013) estimator and a usual unbiased estimator when there is no matching. An empirical study is carried out in support of the present study.
