浅析下岗职工的社会资本降低问题

下岗职工的社会关系 (以下简称“关系”)是下岗职工实现个人行动策略的关键因素 ,也是下岗职工寻求”第二职业”或其它新资源的关键因素 ,本文重点研究国有企业下岗职工所拥有的作为社会载体的社会网络弱化以及在弱化的社会网络中获取资源的能力低弱而带来的社会资本的降低     

军用数字地图中政区的构建及绘制方法

依据境界之间的拓扑数据,采用拓扑分析、边界追踪、边界闭环构建、边界约束下的凸分解、区域填充和边界符号化等技术手段,提出了OpenGL渲染环境下军用数字地图政区的构建方法.通过具体的软件开发和真实数据的测试,证明该方法生成政区准确、符号美观,可适用于不同比例尺下数字地图的显示.该算法具有较强的通用性,遵循国军标的相关规定,已经在相关数字地图软件中得以应用.     

Pakistan's Relations with Central Asia: Is Past Prologue?

Throughout the 1990s Pakistan sought to cultivate ‘strategic depth’ throughout Iran, Afghanistan and the newly emergent Central Asian Republics while seeking to restrict Indian influence in the region. Chastened by its past failures, Pakistan now embraces more modest regional goals. Despite the diminution in objectives, several factors augur failure including Pakistan's policies in Afghanistan, which diminish the likelihood of a stable Afghanistan, and Pakistan's inability to pacify the various insurgencies roiling both Baluchistan and the Pashtun areas of the Federally Administered Tribal Areas as well as the Northwest Frontier Province.     

VISIONS OF FISSION

For many years, non-nuclear weapons states have sought binding commitments from nuclear armed states that they would not be the victim of either the threat or use of nuclear weapons—so-called negative security assurances (NSAs). The nuclear weapon states have traditionally resisted granting such unconditional NSAs. Recent U.S. efforts to use nuclear deterrence against the acquisition and use by other states of chemical, biological and radiological weapons, however, have further exacerbated this divide. This article analyzes the historical development of NSAs and contrasts U.S. commitments not to use nuclear weapons with the empirical realities of current U.S. nuclear weapons employment doctrines. The authors conclude that NSAs are most likely to be issued as unilateral declarations and that such pledges are the worst possible manner in which to handle the issue of security assurance.     

U.S.–RUSSIAN NUCLEAR COOPERATION AND THE CTBT

Post-Cold War “lab-to-lab” collaborations on unclassified scientific issues between U.S. and Russian nuclear weapons laboratories set the stage for bilateral cooperation in materials control and other nuclear areas. They also became the major element in a cooperative process initiated by a Presidential Decision Directive to ensure Russia's compliance with the Comprehensive Nuclear-Test-Ban Treaty. These collaborations have always been highly favored by leaders of the Russian nuclear weapons complex—the same leaders who oversee Russia's participation in various government-to-government programs. This article reviews these collaborations and examines the possibility that U.S. rebuffs of Russian proposals and the U.S. failure to keep promises of expanded collaboration could contribute to Russia's reluctance in major programs and even lead to a return to nuclear testing by Russia. The author argues that a renewed U.S. commitment to the process should be an immediate goal of the Obama administration and is an essential step in re-engaging Russia to solve the nuclear problems remaining from the Cold War. Steps for doing so are recommended.     

利用矩阵求极大相容类的一种方法

寻找相容关系的极大相容类和简单图的极大完全子图,在解决二元关系与数据挖掘和管理决策中的具体问题时有重要作用。利用相容关系的极大相容类与简单图的极大完全子图之间的对应关系,对极大完全子图的路径长度进行分析,得到了关于极大完全子图路径长度的一个定理。并根据该定理构造了一个用矩阵的路径长度搜索简单图的极大完全子图的方法,进而利用该方法找出了对应相容关系的极大相容类。     

关于新疆民族关系的基本思考

新疆地处祖国的西北边陲,占有重要的地理位置,是我国一个重要的历史民族区,有着悠久的历史,民族关系十分复杂。新疆民族关系处理的好坏,直接影响着社会稳定和经济发展及祖国的边防安全。本文从民族关系的一般情况入手,分析了影响新疆民族关系的各种因素,进而分析了新疆民族关系的发展趋势。     

军内行政执法主体研究

军内行政执法主体是指依法享有军内行政执法权的组织。但是,在理论上如何界定军内行政执法主体的范围？军内行政执法主体之间的相互关系如何界定？军内行政执法主体之间的职权在宏观上如何划分？这便是本文所要探讨的问题。     

基于传递闭包的任务时序依赖关系建模方法

建立正确、有效的任务模型是正确引导出信息系统需求的关键步骤。文中针对任务间时序依赖关系,给出与任务建模相关的若干形式定义和命题,帮助分析人员判断任务间的并发和死锁。给出任务间时序依赖关系建模的详细步骤,并根据时序依赖关系的传递性质,给出一种任务关系图上的传递闭包方法,可以帮助分析人员直观地判断任务间时序依赖关系的问题和错误,科学、合理地标记各个任务的时序等级属性,帮助建模人员从全局上明确各个任务在执行时所处的相对位置,以及在每个阶段需要同时展开哪些任务。
