Parental divorce and partnership dissolution in adulthood: Evidence from a British cohort study

From a longitudinal survey of a British cohort born in 1958 this study finds that, by age 33, off-spring of parents who divorced are more likely to have dissolved their first partnerships. This finding persists after taking into account age at first partnership, type of first partnership (marital, pre-marital cohabiting union, and cohabiting union), and indicators of class background and childhood and adolescent school achievement and behaviour problems. Some of these factors are associated with partnership dissolution in their own right, but the association between parental divorce and second generation partnership dissolution is largely independent of them. Demographic factors, including type of and age at first partnership, were important links between parental divorce and partnership dissolution. Moreover, the estimated effects of parental divorce were substantially reduced when the demographic variables were taken into account, suggesting that cohabitation and early partnership may be important pathways through which a parental divorce, or the unmeasured characteristics correlated with it, affect partnership dissolution.     

The measurement of historical trends in fetal mortality in England and Wales

This paper critically discusses recent attempts to estimate long-term trends in the stillbirth rate for England and Wales. It assesses the available historical evidence for the level of late-fetal mortality, drawing especially on examples from Norway, Sweden, and Denmark. A theoretical fetal–infant life table for a high-mortality population is also outlined as a means of analysing the relationship between segments of the conception-to-first-birthday mortality curve. Finally, new estimates of the stillbirth rate for England and Wales are proposed, based on variations in the early neonatal and maternal mortality rates during the 1930s. These estimates are substantially lower than the earlier estimates and are more in keeping with the available evidence from northern Europe. The implications of the revised estimates for interpretations of historical changes in mortality patterns are also considered.     

中欧经贸关系发展趋势及应对

Recent Data on the Number of Adoptions of Foster Children

ABSTRACT

Public agency adoption programs require accurate and current data to identify trends, project caseloads and costs, revise practice and develop financial incentive systems. The federal government and advocacy groups also need accurate and current statistics on adoption to formulate and implement major policy initiatives. Collection of data to establish baselines for the federal Adoption Incentive Program resulted in a re-examination of recent underestimates of the number of adoptions. The underestimates were produced by a convergence of factors including under-reporting by states, use of inappropriate data as the basis for the estimates, and real increases in the number of adoptions.     

国内专门用途英语研究述评(2000—2021年)——基于CiteSpace的可视化分析

借助文献计量工具CiteSpace对2000—2021年间CNKI收录的中文核心期刊、CSSCI来源期刊及辑刊《中国ESP研究》发表的专门用途英语（ESP）相关论文进行可视化梳理,探究国内ESP研究的整体趋势、内容和特点,旨在为相关研究的进一步开展提供参考和启示。研究结果表明：21世纪以来国内ESP研究整体呈上升趋势,热点主题涵盖ESP本体研究、相关教材研究、相关理论与教学研究等;语言学和社会语言学构成了ESP研究的主体领域,跨学科特征虽有所凸显,但研究深度和广度仍有待拓展;从历时发展来看,ESP研究曾涌现商务英语、专业英语、英语教学等多个前沿领域,其中学术写作教学研究是近年关注焦点。     

Rethinking the Univariate Approach to Panel Unit Root Testing: Using Covariates to Resolve the Incidental Trend Problem

In an influential article, Hansen showed that covariate augmentation can lead to substantial power gains when compared to univariate tests. In this article, we ask if this result extends also to the panel data context? The answer turns out to be yes, which is maybe not that surprising. What is surprising, however, is the extent of the power gain, which is shown to more than outweigh the well-known power loss in the presence of incidental trends. That is, the covariates have an order effect on the neighborhood around unity for which local asymptotic power is negligible.     

珠三角农业产业转型升级要素报酬变动趋势分析

通过佛山五区1992—2009年农业生产函数的估计,分析近20年来农业生产要素投入的变动规律和各要素的贡献占比,研究认为:农业要素报酬变动排序为:物质投入、科技进步、土地、劳动力;随时间变化科技进步贡献率的区域变化加大,要素投放的数量和质量变化都呈现"马太效应"。提出经济发达地区以巩固资本积累为前提大力提高农业科技投入,经济欠发达地区着力于发展报酬最高的物质要素投入实现经济增长的转型期对策。
