黄冈市城区小学生生长发育的跟踪调查

1999年至2003年连续5年追踪测量了黄冈市实验小学学生的生长发育状况。被测量的103名学生均为1992年出生。结果表明,黄冈市小学生的身高、体重及克托莱指数均低于全国城市同龄学生,两性身高增长的交叉年龄在11岁,比全国城市平均水平推迟1年,体重没有出线交叉现象,与全国城市学生一致。黄冈市小学生体质发育滞后于全国城市平均水平可能与该地区的社会经济发展水平和学业负担较重有关。

Money Talks: Neural Substrate of Modulation of Fairness by Monetary Incentives

<正>A unique feature of human beings is their compliance with social norms,even though this normative decision often means curbing self-interest.However,money talks sometimes.In other words,once in a while people prefer to pursue wealth at the cost of moral goodness.How human beings make a normative decision when facing a large monetary temptation within a social interaction context is an interesting question.Using the ultimatum game(UG)previous behavioral studies showed deviations from the fairness-related normative decision as a result of high monetary incentives.At high stakes,responders tend to reduce the threshold below which they reject proposals.However,the neural     

Population Genomics Research of Human Admixture History and Local Adaptation

<正>Offi cially set up in January 2011 by Prof.Dr.XU Shuhua at the Partner Institute for Computational Biology,the Population Genomics Group focuses on population genomics research of human admixture history and biological adaptation to the local environment.Population Genomics is a disciplinary to infer population genetic and evolutionary parameters from genome-wide data sets.The ultimate goal of this research group is to understand microevolution mechanisms in human,while genetic admixture is taken as a cut-in point to pursue this
