ABSTRACT

The article argues that current conceptual approaches in civil-military relations are deeply flawed resulting in its irrelevance in analyzing major issues including war and the collapse of democracy. After highlighting major flaws in the work of the late Samuel Huntington and those who follow his approach, the article argues that other conceptual approaches, including Security Sector Reform, are also flawed, or in the case of the “military effectiveness” literature, largely irrelevant. In explaining the main causes of the flawed conceptual literature, the article highlights the absence of good data and challenges in methodology. While arguing that military forces are very unlikely to engage in armed combat, it highlights the roles and missions which in the world today are implanted by these forces. As it is virtually impossible to prove effectiveness of the armed forces in these roles and missions, the article proposes a conceptual approach based on requirements.  相似文献

拓扑关系是一种重要的空间关系,被广泛应用于空间查询和空间分析中。因此定义一个完备、互斥且可以嵌入到空间查询语言中的命名拓扑关系集合有着非常重要的意义。当前,对拓扑关系集合的定义还不能描述那些由点、线或面等不同维几何对象构成的复杂空间对象之间的拓扑关系。针对目前拓扑关系研究的不足,引入了混合几何对象的概念,基于OpenGISSQL规范(OpenGISSimpleFeaturesSpecificationforSQL),定义了一个拓扑关系集合:{disjoint,touches,within,crosses,overlaps,contains,equal}。它扩充了OpenGISSQL规范中拓扑关系的定义和范畴,具有完备性和互斥性,为空间查询语言中的拓扑关系的定义提供了一个统一的框架。  相似文献

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。  相似文献

The military poses an ongoing threat to modern democratic rule in some African countries, especially in the Zimbabwean context. This paper reveals the ways in which Zimbabwe National Army (ZNA) generals have played a political role in the Zimbabwean elections, an issue which is both a political threat and a security threat to the state. It is argued that the ways in which ZNA generals engage in the political process goes against Section 208(2) of the constitution of Zimbabwe, which summarily states that the military must be apolitical. In substantiating this argument, the paper presents and analyses various public speeches made by army generals. It is contended that the army generals’ support of the Zimbabwe African National Union – Patriotic Front (ZANU-PF) and President Robert Mugabe has to be understood as a ‘mutual accommodation’, i.e. the generals are offered privileges in return for the political protection of the ruling regime which negatively impacts the security of the vote.  相似文献

针对高度动态变化的卫星网络,提出一种基于动态拓扑图的可视化方法。动态拓扑图可视化的难点在于如何保持动态可视化过程中的稳定性,从而使用户容易地感知到网络中所发生的拓扑变化。根据卫星网络的动态变化特点,构建连续的动态拓扑图模型;设计一种保持布局稳定性的策略,并基于力引导思想提出一种动态拓扑图布局算法;以Iridium系统为典型实例,验证本文的可视化方法的合理性和可行性。实验表明,该方法能够以清晰的可视化图像支持用户对卫星网络动态拓扑的感知和理解。  相似文献

“As we close this century, there is for the first time realistic hope of a more just future. A Century stained with the sufferings of ceaseless war and atrocity is as much marked by our incomplete efforts to secure the foundations of an international society, one in which all peoples are equal and equally protected from abuse. The last decade has seen the application of dormant humanitarian principles and laws in various fora. The ICC offers us the opportunity to build on these disjointed enforcement efforts. A properly functioning permanent court will be humanity's best chance yet to move out of its self-destructive cycle. Justice is a vindication, a historical right and a deterrent.”  相似文献

ABSTRACT

On 9 July 2018, Ethiopia and Eritrea signed a historical agreement pledging to end their mutual animosity and work for peace. The unprecedented rapprochement was facilitated by the new leadership in Ethiopia, merging interests between the two states and external mediation. This commentary looks into Ethiopian Prime Minister Abiy Ahmed Ali’s early reform initiatives and the dynamics of the rapprochement between Ethiopia and Eritrea.  相似文献
