In the wake of conflict: the long-term effect on child nutrition in Uganda

The Lord’s Resistance Army (LRA) insurgency from 1986 to 2006 is one of the longest conflicts in Uganda. This paper examines the effect of the LRA insurgency on child nutrition using the 2011 Uganda Demographic and Health Survey. The distance from each village to the border of South Sudan is used as an instrument for identifying the intensity of the conflict. We find that each conflict event in a village lowers weight-for-age z-scores and weight-for-height z-scores for children born after the conflict. We further investigate a possible heterogeneous conflict effect on child nutrition in terms of gender, region, and maternal education. Low household wealth, limited access to healthcare, and poor maternal nutrition appear to be channels through which the conflict inhibits the growth and development of children 5 years after the end of the conflict.     

“三元悖论”与中国汇率制度选择

＂三元悖论＂的基本原理是指在货币政策独立、资本自由流动和固定汇率这三个经济目标中最多只能同时实现两个,而该理论本身也存在理论假设过于绝对化,组合难以有效实现,政策组合难以执行的局限性。基于对中国资本流动现状和货币政策有效性分析和＂三元悖论＂的基本原理分析,得出我国的汇率制度选择终级目标是实现＂货币政策独立＋资本自由流动＋自由浮动汇率＂的政策组合。     

Effect of Migration on Children＇s Self-esteem in Rural China

China＇s rapid economic growth has been facilitated by its large volume of rural to urban migration. China ＇s projected future development, especially increasing urbanization, implies that such migration will further intensify. However, migration does not come without cost. There are concerns about the potential negative impacts of migration on children＇s care, education, and, in particular, the self-esteem of children left behind in villages where one or both parents have out-migrated to cities. In this paper, we employ unique survey data collected from Shaanxi Province, where more than 4700 ninth grade students from 36 rural junior high schools in five counties were surveyed in late 2011. The results show that having both parents migrate into cities significantly reduced children ＂s self-esteem. The effects are also gender sensitive. Girls that had a father or both parents who had out-migrated were inclined to have lower self-esteem than boys. Moreover, our study findings indicate that parental migration decreased children ＂s self-esteem more for individuals with initial low self-esteem.     

人民币走向自由兑换的时机选择

汇率制度的选择是一个动态的转换过程。我国目前采用的是钉住美元的汇率制度,这一汇率制度存在着明显弊端,已不适应我国市场经济发展的需要,我国经济的发展迫切需要人民币汇率由钉住汇率转向真正的管理浮动汇率。从现在起到未来的一两年内,是人民币走向浮动,实行人民币自由兑换的最佳时机。

试析流动儿童与城市社会的融合困境

目前学界多认为流动儿童融入城市社会存在重重困难,但这些研究多停留在事实层面。依据南京某民工子弟学校的调查资料,借鉴戈登的族群融合理论和布劳的社会整合理论,从身份认同融合和结构性融合两维度探讨了形成融合困境的原因。     

当前人民币汇率制度选择的理论思考

任何汇率制度都只是实现经济目标的手段而不是目的,我们在各个时期选择的汇率制度应该是对我国经济发展最有利的制度。在现有的国际货币体系下,如果资本项目尚未开放,则理性的选择应该是固定汇率制度;如果资本项目已完全开放,则实行浮动汇率制是有效而保险的。对于中国这样一个资本账户部分开放的国家,现阶段重新回到真正意义上的有管理的浮动汇率制是必要的,也是可行的。     

大型沉管管节浮运航道适航特性建模分析

为确保沉管隧道在航道中长期浮运作业的安全性与可靠性,依托深中通道工程备选预制厂方案,建立珠江口局部区域二维水流数学模型,在实测水文资料验证的基础上,通过模型计算揭示了浮运航道的水动力变化特征,开展航道范围内横流、纵流的变化特点分析.分析结果表明:工程实施后,龙穴港池水域的潮流流速普遍较弱,南沙四期港池水域流速变化较小,...

从儿童肱骨髁上骨折畸形愈合看儿童骨骼组织的塑型能力

为探讨儿童骨骼的塑型能力,对湖北理工学院附属医院门诊收治的9例儿童肱骨髁上骨折因未及时复位或处理不当,导致骨折畸形愈合的情况进行回顾性分析。结果为9例肱骨髁上骨折畸形愈合经过6～8个月的自行塑型而达到了完全功能康复。儿童发育期间的骨组织具有很强的塑型能力。
