National Security Letters,the USA PATRIOT Act,and the Constitution: The tensions between national security and civil rights

In response to the terrorist attacks of 9/11, the USA PATRIOT Act greatly expanded the ability of the Federal Bureau of Investigation to use National Security Letters (NSLs) in investigations and the contexts in which they could be used by relaxing the standards under which NSLs could be employed. NSLs allow investigators to acquire a significant amount of information about the subject of an investigation, and the range and frequency of uses of NSLs has risen dramatically since the passage of the USA PATRIOT Act. An outstanding question with NSLs is whether they are being used in a manner that violates the First and Fourth Amendments of the Constitution. This article explores the relationships between NSLs, the USA PATRIOT Act, and the Constitution. The paper reviews the legislative history of NSLs, synthesizes the First and Fourth Amendment issues and key judicial decisions related to NSLs, and analyzes the extent to which the USA PATRIOT Act Improvement and Reauthorization Act of 2005 adequately addresses challenges to the constitutionality of NSLs. The paper concludes with an examination of NSLs within the greater information policy context in the United States, as the expanded usage of NSLs—even if entirely constitutional—raises the possibility of chilling the freedom of expression.

基于格的多信任域认证路径的选择算法

在PKI的多信任域认证技术中,域间证书路径的构建是一个非常复杂的过程,现有算法实现起来复杂、耗时,使得域间证书路径构建的效率很低。本文提出了一种基于格的多信任域认证路径算法,该算法以格的偏序运算为基础,定义了不同的偏序运算实现不同的多信任域认证路径的选择,以集合运算为例,提出域间证书路径构建算法。经分析计算,跨信任域的认证路径的选择算法是高效的,密码体制有很高的安全性和保密性。     

外资并购反垄断审查与国家安全审查制度比较研究

外资并购境内企业法律审查应遵循三大基本原则：平衡协调、维护公平竞争、国民待遇。外资并购反垄断审查与国家安全审查法律制度之间既存在重要区别,也需要相互协调配合。我国应健全反垄断审查与国家安全审查协调机制,改进外资并购境内企业审查制度体系,完善相关立法及执法程序。

我国被征地农民社会保障制度研究

近年来,随着工业化、城市化的迅猛发展,土地征收过程中的问题和矛盾日渐突出,被征地农民的社会保障凸显的问题已经成为构建和谐社会,建设社会主义新农村的制约性瓶颈。政府必须进一步完善被征地农民的社会保障制度。     

第三次印支战争早期东盟安全观念与对策分析(1979-1982)

1978年越南入侵和占领柬埔寨严重危害了东南亚地区和平与安全,破坏了东盟最基本的安全规范。在共同的威胁面前,东盟成员国的安全观经历了一段磨合期,形成了一套渐趋强硬的集体立场。东盟的努力,有效维持了国际社会对柬埔寨问题的持续关注,为政治解决柬埔寨问题做出了重大的贡献。     

The Rules Grid: helping children with social communication and interaction needs manage social complexity

This article introduces a new practical visual approach, the Rules Grid, to support children who have social communication and interaction needs. The Rules Grid involves a system whereby behaviours of concern can be broken down into smaller behavioural manifestations which in turn lead not only to problem identification and specification, but provide a visible structure to support behaviour change at a reasonably micro level. The paper provides an overview of the theory and research that support visual approaches before outlining some important examples of visual strategies. This is followed by a presentation of a single case study which illustrates how the Rules Grid could be used.
