论妨害公务罪的行为客体

妨害公务罪的保护客体是公务，其行为客体是正在依法执行职务的国家公务人员，包括人之要素、事之要素、时之要素和地之要素。人之要素为国家公务人员；事之要素为依法执行之公务；时之要素为依法执行职务之时；地之要素为依法执行职务之区域。     

关于村民自治进程中乡镇政府权力渗透的思考

自村民自治实施以来 ,农村的社会民主取得了极大的发展。然而 ,乡镇政府对村级组织特别是村委会的权力渗透和扩张严重地制约了村民自治 ,阻碍了农村基层民主建设。因此 ,必须实现乡镇政府从领导职能向指导职能的转变 ,应通过加强对乡镇领导干部的思想教育 ,明确乡镇政府的管理权限 ,改革对乡镇政府政绩考核办法等措施加以解决。     

用低相干光干涉测绘物体表面三维轮廓的立体分布

利用白光干涉对精密物体(如芯片、半导体、LCD等)进行表面轮廓立体分布的测绘,是国际上目前较为先进的技术.白光干涉测量术采用Michelson光路结构和宽频带光源,并且使用CCD作为接收探测装置.在用低相干度光源测绘物体表面三维立体分布的实验系统中,由于设计了新的算法(局部积分法)来计算光强包络面曲线峰值.因此与同类实验装置相比,其具有运算速度快(提高了近两倍)、抽样间隔大(为100nm)、精密度高(实验不确定度为5nm)、视野范围大(10mm×10mm)等特点.即使物面错综复杂,也能得到很好的测量结果.

Silence of the genes

The 2006 Nobel Prize in Physiology or Medicine was awarded to Andrew Fire and Craig Mello for discovering “RNA interference—genesilencing by double-stranded RNA”. The Nobel Committee at the Karolinska Institute in Sweden selected them for the award for unraveling “a fundamental mechanism for controlling the flow of genetic information” that is “already being widely used in basic science as a method to study the function of genes and may lead to novel therapies in the future”. This has been one of the fastest Nobel Prizes conferred in physiology or medicine, considering that Fire and Mello published their path-breaking article in the journal Nature in 1998, less than ten years ago. Utpal Nath is an Assistant Professor in the Department of Microbiology and Cell Biology, IISc. His laboratory is studying the genetic mechanisms of plant development. Saumitra Das is an Associate Professor in the Department of Microbiology and Cell Biology, IISc. His laboratory is interested in the translational control of cellular and viral RNA.     

保障成本分担均衡、试错博弈与政府干预——论"四位一体"劳务派遣市场建立

劳务派遣对缓解我国就业压力起到了重要作用,但由于其法律关系区别于传统劳动关系,具有“三方主体、关系复杂”的特点,各方权利和义务的界定一致是学术界研究的热点。文章通过建立“派方与要方成本分担均衡模型”和“试错博弈均衡模型”,分析了劳务派遣市场的均衡及其实现过程,并得出政府确定保障成本、政府与派遣方和要派方三者持续博弈和试错是实现劳动者权益最大化的两个条件。在模型分析基础上,提出了建设“四位一体”劳务派遣市场的构想和策略。

牛顿环实验的研究

利用公式推理和实践测量对牛顿环实验中环中心出现亮纹、环内凹、环中心出现较大暗斑的变形牛顿环进行了分析，结果表明，环中心出现亮纹、环内凹变形牛顿环对透镜曲率半径测量结果无影响，而环中心出现较大暗斑的变形牛顿环会使透镜曲率半径的测量结果偏大于真值。     

Interference and Inhibition in Cognition and Behavior: Unifying Themes for Educational Psychology

In this article, we review modern work on interference and inhibition in cognition and behavior. We begin by briefly reviewing the historical and conceptual roots of this new body of work. Next we discuss five new theoretical frameworks that use the concepts of interference and inhibition to explain cognitive and behavioral phenomena. In the section that follows, we review evidence of individual and developmental differences in inhibition and susceptibility to interference in at-risk students. We then consider the implications of this new body of work for research on educational psychology by discussing six selected areas of research: intelligence, strategies, reading comprehension, logical and mathematical reasoning, self-regulated learning, and retention. In the next section, we explore four critical issues that pose significant challenges to research in inhibition and interference. Finally, we discuss the relevance of this work to educational practice by focusing on its implications for the curriculum and instruction. Throughout, our principal goal is to bring this new body of work to the attention of the readers of this journal and to show how it might be useful in guiding research and theory in educational psychology.
