The Impact of Prenatal Exposure to Power Plant Emissions on Birth Weight: Evidence from a Pennsylvania Power Plant Located Upwind of New Jersey

To examine the infant health impact of prenatal exposure to power plant emissions, we draw scientific evidence on the impacted region downwind of a large polluter, a coal‐fired power plant located on the border of two states and proven to be the sole contributor to the violation of air quality standards of the impacted region. Our results show that among all live singleton births that occurred during 1990 through 2006, those born to mothers living as far as 20 to 30 miles away downwind from the power plant (which is also an affluent region) during pregnancy are at greater risks of low birth weight (LBW) and very low birth weight (VLBW): the likelihoods of LBW and VLBW could increase approximately by 6.50 and 17.12 percent, respectively. In light of the continual efforts of The U.S. Environmental Protection Agency in reducing cross‐state air pollution caused by transboundary power plant emissions, our study is aimed at broadening the scope of cross‐border pollution impact analysis by taking into account adverse infant health effects of upwind polluters, which can impose disproportionate burdens of health risks on downwind states due to air pollutants transported by wind.     

传承与发展：关于我国经侦运行机制的思考

改革开放30年来经济犯罪形势发生剧变的同时,我国经侦运行机制也随之不断完善。进入21世纪,现行经侦运行机制的不足之处日益显现,主要表现为警令不畅致使国家打击经济犯罪的决策难以彻底落实、执法活动中的地方保护主义异常严重、对经济犯罪的打防难以形成常态化的高压态势。为此,必须通过规范地方各级经侦机构建设、在全国范围内设置垂直领导的中央经侦机构等创新性举措完善现有经侦运行机制,从而以制度创新化解当前经侦部门面对的空前挑战。     

复杂性视域下阿马蒂亚·森发展观的多维审视

复杂性科学提供了一种新的思维方式和方法论,被人文社会科学的学者广泛重视,它具有动态多变性、非线性、自组织性、非加和性、不可还原性等特征。阿马蒂亚·森在质疑以简单性思维为基础的传统发展观基础上,立足于开放社会的复杂系统,用复杂性思维去探索发展问题,提出以人为本的发展观、能力发展观、自由发展观,超越了传统发展观的机械论、还原论等局限,对中国避免西方发达国家弊端,实践科学发展观不无裨益。     

Commentary on the Newly Published White Paper Concerning the Rule of Law in China

On February 28, 2008, the State Council Information Office published a white paper entitled China＇s Efforts and Achievements in Promoting the Rule of Law. This document is the first white paper published by the government on China＇s rule of law. It contains eight chapters and six appendices to review China＇s achievements on the road to practicing the rule of law in a compre- hensive way, and to expound the official Chinese policy and position on this is- sue. With some essential points inside, the publication of this white paper is of great significance, especially this year, to China＇s rule of law, human rights prog- ress, and its communication and dialogue with the international community.

中国沿海外商直接投资外移趋势分析

受外商投资区位优势加速变迁,国际经济环境剧烈变动,尤其是全球金融危机冲击实体经济,各国对国际直接投资(FDI)的争夺日趋激烈等因素影响,中国沿海地区劳动密集型制造业的FDI大量外移。减少FDI向国外转移,促进其向内地转移,既有利于沿海发达地区经济结构升级,又有利于推动内地经济发展和对外开放,加快中国工业化进程,增加国内就业机会。促进沿海劳动密集型制造业的FDI内移,必须正视中国二元经济结构的现实,避免工业化进程中好高骛远,选择内地区域中心,形成产业集群效应,拓展产业链条,降低外商投资内地的综合成本。     

日本、印度金融支持农村基础设施建设的经验及启示

日本、印度两国在农村基础设施建设过程中,有多种金融机构提供多样化的金融服务,如日本的农协、农林渔业金融公库,印度的国家农业和农村开发银行等,为农村基础设施建设提供了贷款、担保等服务,确保了农村基础设施建设的金融需求。日本、印度的金融支持农村基础设施建设的实践给我国提供了有益的启示。     

北京鸭Ⅱ型干扰素基因分子克隆与序列分析

应用反转录-聚合酶链反应(RT-PCR)技术,从伴刀豆球蛋白A(ConA)刺激培养的北京鸭脾淋巴细胞提取的总RNA中扩增得到北京鸭Ⅱ型干扰素(1FN-γ)基因(DuIFN-γ2).序列分析表明,DuIFN-γ2基因长度与报道的鸭IFN-γ基因(AF087134)长度一致,为497个核苷酸,共编码145个氨基酸的成熟蛋白,推测其分子量约17 ku.两者核苷酸水平的同源性为99.6%,有2个位置发生非同义变异,其氨基酸序列的同源性为98.6%;与其他禽类的同源性为67.0%-68.0%,与人的同源性为34.4%.     

马动脉炎病毒的血凝性研究

在RK-13细胞上培养的马动脉炎病毒(Equine viral arteritis,EAV)在4℃、室温和37℃条件下,用多种动物的红细胞进行血凝试验,病毒在不同温度下均可凝集小鼠和鸡的红细胞,但不能凝集牛、绵羊、山羊、马、猪、豚鼠、仓鼠、兔及鹅的红细胞.将病毒用吐温-80和乙醚处理后,血凝活力会显著增强,其HA效价比未经处理的病毒高4-8倍,且血凝像更加清晰.处理病毒的最适条件是在冰浴状态下用终浓度0.6-1.25 mL/L吐温-80振荡处理15-60 min,再加1/2体积的乙醚振荡作用5-15 min.
