Does Part-Time Mothering Help Get a Job? The Role of Shared Custody in Women’s Employment

Though child shared physical custody arrangements after divorce are much more frequent and parents who use it more diverse in many European countries, little is known about their economic consequences for parents. By relaxing family time constraints, does shared custody help divorced mothers return to or stay on work more easily? Since lone mothers are one of the least-employed groups, and they face high unemployment rates, the type of child custody arrangement adopted after divorce is of particular interest for their employability. This article analyses to what extent the type of child custody arrangement affects mothers’ labour market patterns after divorce.Using a large sample of divorcees from an exhaustive French administrative income tax database, and taking advantage of the huge territorial discrepancies observed in the proportion of shared custody, we correct for the possible endogeneity of shared custody. Results show that not repartnered mothers with shared custody arrangements are 24 percentage points more likely to work one year after divorce compared to those having sole custody, while no significant effect is found for repartnered mothers. Among lone mothers, we also highlight huge heterogeneous effects: larger positive effects are observed for previously inactive women, for those belonging to the lowest income quintiles before divorce, for those with a young child, and for those who have three or more children. Thus, shared physical custody arrangements may reduce work–family conflict by diminishing childcare expenses and enlarge the possibilities to find a suitable job because of more relaxed time constraints for lone mothers.

Efficient Algorithms for Determining 3-D Bi-Plane Imaging Geometry

Biplane projection imaging is one of the primary methods for imaging and visualizing the cardiovascular system in medicine. A key problem in such a technique is to determine the imaging geometry (i.e., the relative rotation and translation) of two projections so that the 3-D structure can be accurately reconstructed. Based on interesting observations and efficient geometric techniques, we present in this paper new algorithmic solutions for this problem. Comparing with existing optimization-based approaches, our techniques yield better accuracy and have bounded execution time, thus is more suitable for on-line applications. Our techniques can easily detect outliers to further improve the accuracy.This research was supported in part by NIH under USPHS grant numbers HL52567.     

中华武术散打之局部力量与整体力量解读

散打之力量是散打运动中除运动技术等要素外,非常重要的另一要素,散打之力量在运动中表现出两个方面的应用,即散打之局部力量和整体力量;散打之局部力量和整体力量在比赛中交替展现,正是由于散打之局部力量和整体力量的不停变换使用及不同情况下各种力量共同作用,运动员才能在比赛中赢得胜利。散打之局部力量与整体力量的科学应用与训练不仅塑造了练习者完美的运动身形,而且培养了个人不凡的运动气质,是一项完美的体育运动。     

四维哲学的几个基本问题

人类在认识过程中,所基于的物质维次越高,认识结果与事物的本质就越接近。个体与系统是物质世界的两个最基本的构成要素;个体之间的作用关系,个体与系统之间的层次关系是物质三维形态的最基本关系。物质四维形态是由"原因+运动形式=结果"这一公式构成的若干循环过程。     

上市公司并购重组与企业整体资产评估

随着我国证券市场的日益发展和完善,上市公司间的兼并、收购和资产重组等经济活动日趋频繁,企业整体资产评估是并购重组过程中资产业务的基础,是资产或产权交易的前提条件。尽管实践中可以通过多种估价方法来估测企业整体资产的价值,但由于我国资产评估市场尚不成熟,企业整体资产评估缺乏科学、可行的评估体系,评估结果难以真正地反映企业整体资产的内在价值。因此,必须采取有效措施规范资产评估市场,提高整体资产评估的质量,为证券市场的健康发展打下良好的基础。     

盈余管理泛滥的制度原因与治理——基于中美资本市场的比较分析

盈余管理是导致会计信息失真,困扰资本市场有效运行的一大痼疾.其泛滥根本原因在于制度安排缺乏对滥用准则行为的有力制约,甚至产生诱导效果,而不是因为准则中存在可被利用的空间,与美国相比,我国的问题是尚未建立盈余管理的约束机制.治理盈余管理不能依靠修订会计准则,而应改进现有制度安排以强化阻碍力量,尤其政策上应变被动防范为主动查处,对滥用准则行为说"不".
