1To Board or Not to Board: Evidence from Nutrition, Health and Education Outcomes of Students in Rural China显示文摘寄宿学校是否为学生是有益的争论仍然在发展和发达国家存在。在农村中国,由于在 2001 开始了的一个国家学校兼并节目,上学生的数字戏剧性地增加了。然而,很少研究都没被做测量登机地位怎么可以与营养,健康和教育结果被相关。在这篇论文,我们比较不搭伙的学生登机到那些用的结果一大,在中国越过五个省包括 59 个农村县的总数数据集。我们发现为登机的所有结果,学生们表演比不搭伙的学生更坏。尽管有这些差别,所有结果的绝对层次为登机和不搭伙的学生是低的,显示对将指向不管他们的登机地位的所有农村学生的新政策的需要。Aiqin Wang Alexis Medina Renfu Luo Yaojiang Shi Ai Yue 2016China & World Economy2016,24,3:10
2Effects of Parental Migration on Mental Health of Left-behind Children: Evidence from Northwestern China显示文摘瓷器快速的开发和都市化劝诱了大量农村居民寻找更高的工资在农村从他们的家移居到城市的区域。有超过 6000 万 “left-behind children” ,这被估计(LBC ) 在他们的父母移居以后,留在农村,典型地与代理人 caregivers 住在一起。广泛的研究在孩子上集中了于父母外面迁居的影响心理健康,而是更少的注意被付了到父母回来迁居的效果。在第四和第五的父母分级学生外面移居或回来移居前后,现在的论文处于心理健康检验变化。我们在 252 所农村小学的超过 19000 个学生的作者在西北的中国收集的面板数据集上绘画。使用做了并且倾向分数匹配途径,我们的结果显示父母外面迁居在 LBC 的心理健康上有重要否定影响,,他们趋于展出焦虑的高水平和自尊的底层。然而,我们发现父母回来迁居没在 LBC 的心理健康上有重要效果。Yaojiang Shi Yu Bai Yanni Shen, Kaleigh Kenny Scott Rozelle 2016China & World Economy2016,24,3:8
3Impact of a Senior High School Tuition Relief Program on Poor Junior High School Students in Rural China显示文摘A significant gap remains between rural and urban students in the rate of admission to senior high school.One reason for this gap might be the high levels of tuition and fees for senior high school.By reducing students' expectations of attending high school,high levels of tuition and fees could be reducing student academic performance in junior high schools.In this paper we evaluate the impacts of a senior high tuition relief program on the test scores of poor rural seventh grade students in China.We surveyed three counties in Shaanxi Province and exploited the fact that,while the counties are adjacent to one another and share similar characteristics,only one of the three implemented a tuition relief program.Using several alternative estimation strategies,including difference-in-differences,propensity score matching and difference-in-differences matching,we find that the tuition program has a statistically significant and positive impact on the mathematics scores of seventh grade students.More importantly,this program is shown to have a statistically significant and positive effect on the poorest students in the treatment group compared to their wealthier peers.Xinxin Chen Yaojiang Shi Di Mo James Chu Prashant Loyalka Scott Rozelle 2013China & World Economy2013,21,3:3
4Roots of Tomorrow's Digital Divide:Documenting Computer Use and Internet Access in China's Elementary Schools Today显示文摘This paper explores China's digital divide,with a focus on differences in access to computers,learning software,and the Internet at school and at home among different groups of elementary school children in China.The digital divide is examined in four different dimensions:(i) between students in urban public schools and students in rural public schools;(ii) between students in rural public schools and students in private migrant schools;(iii) between migrant students in urban public schools and migrant students in private migrant schools;and(iv) between students in Han-dominated rural areas and students in areas inhabited by ethnic minorities.Using data from a set of large-scale surveys in schools in different parts of the country,we find a wide gap between computer and Internet access of students in rural areas and those in urban public schools.The gap widens further when comparing urban students to students from minority areas.The divide is also large between urban and rural schools when examining the quality of computer instruction and access to learning software.Migration does not appear to eliminate the digital divide,unless migrant families are able to enroll their children in urban public schools.The digital divide in elementary schools may have implications for future employment,education and income inequality in China.Yihua Yang Xiao Hu Qinghe Qu Fang Lai Yaojiang Shi Matthew Boswell Scott Rozelle 2013China & World Economy2013,21,3:2

8Interfacial Microstructure and Mechanical Properties of Al Alloy/Mg Alloy Laminated Composite Plates Fabricated by Equal Channel Angular Processing显示文摘KAl(7075)alloy/Mg(AZ31)alloy laminated composite plates were successfully fabricated by the equalchannelangular processing(ECAP)by using route A for 1,2,and 3 passes at 573 K,respectively.After fabrication,the 1-pass ECAPed laminated composite plates were annealed at different temperatures.The microstructure evolution,phase constituent,and bonding strength near the joining interface of Al(7075)alloy/Mg(AZ31)alloy laminated composites plates were evaluated with scanning electron microscopy,X-ray diffraction,and shear tests.The experimentalresults indicated that a 20 μm diffusion layer was observed at the joining interface of Al(7075)alloy/Mg(AZ31)alloy laminated composites plates fabricated by the 1-pass ECAP,which mainly included Al_3Mg_2 and Mg_(17)Al_(12) phases.With the increase of passes,the increase of diffusion layer thickness was not obvious and the form of crack in these processes led to the decrease of bonding strength.For 1-pass ECAPed composites,the thickness of diffusion layer remained unchanged after annealed at 473 K,while the bonding strength reached its maximum value 29.12 MPa.However,after elevating heat treatment temperature to 573 K,the thickness of diffusion layer increased rapidly,and thus the bonding strength decreased.李国瑞 ZHAO Dong ZHAO Yaojiang ZHOU Bin 王红霞 2016Journal of Wuhan University of Technology(Materials Science)2016,31,2:1

11Educational Expectations and Dropout Behavior among Junior High Students in Rural China显示文摘来自初中学校的退学学生的高水平是在瓷器农村区域面对工人的下一代的人的大写的发展的最严肃的挑战之一。这份报纸的目标是估计到到什么程度,学生的教育期望在中国在初中学校水平与退学学生行为被相关。用面板数据,这研究发现累积退学学生率在在我们的样品以内的等级 7 和 8 学生之中高(象 19.5% 一样高,它暗示约 25% 的 3 年的退学学生率) 。重要地,我们发现退学学生的这高率显著地与学生一起被相关教育期望。明确地,报导他们教育的期望的水平比高 school” 是 “less 的学生或 “less 比 college”更多半是五次和四次分别地比他们的同伴在初中学校期间放弃。Fang Chang Wenbin Min Yaojiang Shi Kaleigh Kenny Prashant Loyalka 2016China & World Economy2016,24,3:1
