    自20世纪90年代以来,外商直接投资(FDI)作为一种重要的经济现象在全球化的舞台上扮演着越来越重要的角色。外商直接投资的存在和发展对东道国和母国的经济都产生了重要的影响。我国改革开放以来,一直把引进外商直接投资作为经济开发的重要政策之一。福建省是我国吸引外商直接投资较早的主要地区之一。外商直接投资的存在对福建省经济的方方面面都产生了巨大的影响,因此,本文以福建为样本,致力于研究FDI流入的工资效应。As an economic phenomenon, foreign direct investment (FDI) has played a more and more important role in global economy since the 1990s. It has a great impact on the economic development of both the parent country and the host country. Attracting FDI has been a long term policy in China since the opening-up in 1978. Fujian is a province with the greatest potential to gain FDI. FDI influences ec...学位:经济学硕士院系专业:经济学院经济研究所_政治经济学学号:2005130267

The results indicated that the established detection system could efficiently detect all positive plasmids with sensibility to 10copies. Four kinds of fusion gene types such as MLL-AF4,MLL-AF9,MLL-AF10,MLL-ELL could be detected in 54 samples,the sequencing of positive samples showed consistency of sequencing results with detectionresults. It is concluded that a novel multiplex real-time PCR detection method is established which can detect 10 common MLL fusion genes covering about 90% of the cases harboring MLLfusions. This method is fast,sensitive,specific and reliable,and should be an useful clinical tool for identification and management of leukemia patients with MLLfusions.厦门大学医学院博士点基金项目基金资

    在河西走廊黑河地区沙漠和绿洲下垫面生态条件下,用涡旋相关法研究了能量输送的不同模式和日变化进程;以及两种生态条件下能量输送间可能存在的相互关系。在沙漠生态条件下,大部分净辐射用于显热散失,另一部分用于向地下传输,较少部分则用于潜热输送,其方向在白天向下,在夜间向上;其Bowen比为13.16。在绿洲的麦田生态条件下,能量输送的基本模式为:大部分净辐射用于潜热散失,其输送方向与沙漠相反,另一部分用于显热散失,其输送方向一般在午后约3h即由上传转为下传。土壤热通量在最大时一般不超过40W/m2。冠层光合作用固定的能量则更小,其数量级维持在10W/m2以下,小麦不同生长阶段各能量分量占净辐射的比例有所变化。麦田的Bowen比从分蘖期的0.33降到拔节期末的0.095。当有干热大风自沙漠吹向绿洲时观测了典型的绿洲效应,其能量输送模式发生很大变化,显热显著下传,地热流量减弱,潜热散失强烈,起风后约2h潜热甚至高于净辐射。表明沙漠的能量组分参与了麦田的能量平衡过程。 【英文摘要】 With eddy correlation,we studied the pattern and dinurnal variation course of energy transfer for the underlying surface of desert and wheat field in oasis and their possible relationship between two ecological conditions at Heihe River region in Hexi Corridor during the HEIFE project.In the desert,the most net radiation( Rn )was consumed by sensible heat( H )transfer,another part of Rn conducted into desert surface,and a small part of Rn was dissipated by latent heat( LE ) transfer on a fine ...中国科学院资助项目;;国家自然科学基金;;日本文部省资助项

    泛素家族包括泛素及类泛素蛋白,约20种成员蛋白.近年来,泛素家族领域取得了迅猛发展,并已与生物学及医学研究的各个领域相互交叉.泛素家族介导的蛋白质降解和细胞自噬机制的发现分别于2004和2016年获得诺贝尔奖.但是,类泛素蛋白并没有统一规范的中文译名. 2018年4月9日在苏州召开的《泛素家族介导的蛋白质降解和细胞自噬》专著的编委会上,部分作者讨论了类泛素蛋白的中文命名问题,并在随后的\"泛素家族、自噬与疾病\"(Ubiquitinfamily,autophagy anddiseases)苏州会议上提出了类泛素蛋白中文翻译草案,此草案在参加该会议的国内学者及海外华人学者间取得了高度共识.冷泉港亚洲\"泛素家族、自噬与疾病\"苏州会议是由美国冷泉港实验室主办、两年一度、面向全球的英文会议.该会议在海内外华人学者中具有广泛影响,因此,参会华人学者的意见具有一定的代表性.本文介绍了10个类别的类泛素蛋白的中文命名,系统总结了它们的结构特点,并比较了参与各种类泛素化修饰的酶和它们的生物学功能.文章由45名从事该领域研究的专家合作撰写,其中包括中国工程院院士1名,相关学者4名,长江学者3名,国家杰出青年科学基金获得者18名和美国知名高校华人教授4名.他们绝大多数是参加编写即将由科学出版社出版的专著《泛素家族介导的蛋白质降解和细胞自噬》的专家
