Effects of child support and welfare policies on nonmarital teenage childbearing and motherhood

This paper is an assessment of the impact of child support enforcement and welfare policies on nonmarital teenage childbearing and motherhood. We derive four hypotheses about the effects of policies on nonmarital teenage childbearing and motherhood. We propose that teenage motherhood and school enrollment are joint decisions for teenage girls. Based on individual trajectories during ages 12–19, our analysis uses an event history model for nonmarital teenage childbearing and a dynamic model of motherhood that is jointly determined with school enrollment. We find some evidence that child support policies indirectly reduce teen motherhood by increasing the probability of school enrollment, which, in turn, reduces the probability of teen motherhood. This finding suggests that welfare offices may wish to place greater weight on outreach programs that inform more teenagers of the existence of strong child support enforcement measures. Such programs might reduce nonmarital teen motherhood further and thus reduce the need for welfare support and child support enforcement in the long run.

WTO的和谐理念初探——WTO法的一种中国式解读

对和谐、和谐世界的向往,不是中国特有的,而是一种人类的共性。WTO语境下的和谐理念可以解析为"非歧视原则"中蕴含的平等观、法价值冲突的协调平衡原则以及对发展中国家(尤其是最不发达成员)的特殊与差别待遇等。多哈部长会议宣言从多方面实现了WTO和谐理念的进一步发展,体现了作为现行最为重要和行之有效的国际经济规则的WTO制度对将建立兼具自由、平等、有序、发展的和谐世界经济作为其最终价值追求的重视。     

Changes in Parenting and Youth Adjustment Across the Military Deployment Cycle

This study examined how changes in at‐home parents' mental health and parenting practices related to changes in their children's adjustment throughout the course of a service members' military deployment. Participants included at‐home parents from 114 National Guard families who were interviewed at four different occasions across the deployment cycle. The results revealed changes across the deployment cycle among the following three indicators: parental warmth, depressive symptoms, and children's externalizing behaviors. Changes in parental warmth were associated with changes in children's adjustment. Overall, these findings indicate that during parental separation, at‐home parents' responses to children have important implications for children's adjustment.     

Case Reading as a Practice and Training Intervention in Domestic Violence and Child Protection

This article explores the role of a case-reading tool, developed by the Safe and Together Institute, deployed across five Australian states, and which engaged workers from child protection (CP) and specialist domestic and family violence (DFV) services. It aimed to assess the extent to which DFV is identified in CP case files and to assess the quality of case practice from a DFV-informed perspective, as documented in the case file. The Safe and Together approach to child welfare provides a robust foundation upon which practitioners from statutory and nonstatutory backgrounds can work collaboratively and reach consensus about how best to ensure the safety and wellbeing of children living with DFV. The case reading is both a process of transformative working for practitioners and an analytical tool through which their agencies can affect systemic change.

IMPLICATIONS

• A national audit of 20 child protection case files using the Safe and Together case-reading process indicated that documented child protection practice sits at the lower end of a domestic and family violence-informed Continuum of Practice.

• Analysis indicates a need to improve: child protection engagement with fathers who use DFV, assessments of their parenting role and its impact on children and family functioning; identification of adult survivors’ protective capacities and their impact on children.

• Research in this area may have broader implications for other professions and government policy both nationally and internationally.

     

Parental divorce, sibship size, family resources, and children’s academic performance

Using data from 19,839 adolescents from the National Education Longitudinal Study, this study investigates whether the effects of parental divorce on adolescents’ academic test performance vary by sibship size. Analyses show that the negative effect of divorce on adolescent performance attenuates as sibship size increases. On the other side of the interaction, the inverse relationship between sibship size and test performance is weaker in disrupted than in two-biological-parent families. Trends of such interactions are evident when sibship size is examined either as a continuous or a categorical measure. Finally, the observed interactions on adolescents’ academic performance are completely explained by variations in parental financial, human, cultural, and social resources. In sum, this study underlines the importance of treating the effect of parental divorce as a variable and calls for more research to identify child and family features that may change the magnitude of such an effect.     

Using Bayesian graphical models to model biases in observational studies and to combine multiple sources of data: application to low birth weight and water disinfection by-products

Summary.  Data in the social, behavioural and health sciences frequently come from observational studies instead of controlled experiments. In addition to random errors, observational data typically contain additional sources of uncertainty such as missing values, unmeasured confounders and selection biases. Also, the research question is often different from that which a particular source of data was designed to answer, and so not all relevant variables are measured. As a result, multiple sources of data are often necessary to identify the biases and to inform about different aspects of the research question. Bayesian graphical models provide a coherent way to connect a series of local submodels, based on different data sets, into a global unified analysis. We present a unified modelling framework that will account for multiple biases simultaneously and give more accurate parameter estimates than standard approaches. We illustrate our approach by analysing data from a study of water disinfection by-products and adverse birth outcomes in the UK.     

Migrant women’s economic success in Russia: objective reality and subjective assessment

This study contributes to the growing body of literature on the outcomes of labour migration by focusing on the effects of migrant legal status on the economic and perceptual measures of migration success. To study the effects of legal status, we use a sample of Central Asian migrant women who work in Russia and of their native counterparts who occupy the same positions on the labour market. Similar to the studies in the developed settings, we find that a temporary legal status is associated with an earnings penalty and that permanent legal status corrects this earning disparity. We also find that both temporary and permanent migrant status is positively associated with perceptions of pay inequality but that, irrespective of these perceptions, both types of migrants are more likely to be satisfied with their jobs than natives. We interpret these findings within the legal and social context of migrant economic incorporation in Russia and relate them to the findings from other migrant-receiving settings.     

Child support and non-resident fathers’ contact with their children

The paper presents a model of a non-resident father’s child support and contact with his child, which combines the public good treatment of “child quality” with “trade” in father–child contact time in a setting of non-cooperative interaction. It predicts that father’s income and mother’s non-labour income should have exactly the same effect on the frequency of father–child contact if he chooses to make lump sum payments to the mother. If he does not or there is a binding child support payment order, they have effects opposite in direction. A higher binding support order reduces father–child contact but may well raise “child quality”.

独生子女规模估算及其对政府奖励性支出的影响——以苏州市为例

本文将抽样调查资料与人口普查资料相结合,利用多种统计方法、多方案推算苏州市独生子女存量规模以及未来各年数量,并据此测算了未来各年政府可能的配套奖励性支出。研究结果表明：独生子女大规模进入婚育年龄将势必引起政策生育率的上升,未来各年政府用于独生子女家庭及其父母养老等计划生育政策奖励性支出将逐年增加．财政负担日益加重。建议政府对计划生育配套奖励政策适时进行调整,由现行的提供物质奖励向提供优质服务和社会保障转变。
