We address empirically the question of why international economic sanctions are, or are not, chosen as instruments of foreign policy and the question of what determines their success. We hypothesize that cultural linkages between nations are an important factor in explaining both instrument choice and conflict outcomes. Countries that share significant cultural attributes are found to be less likely to apply economic sanctions against one another than countries lacking such cultural ties. However, it is precisely in the case of culturally similar sender and target nations that sanctions are most likely to succeed.  相似文献

TANZANIA     
Protracted state collapse in Somalia has led to a multiplication and diversification of armed groups. We can speak of at least five types of armed group: faction, warlord, business, court, and Islamic militias. These groups differ in important ways, yet often are simply classified as ‘militia’ or ‘warlord’. This essay seeks to add a measure of analytical rigour to the classification of armed groups and provides a comparison using a framework of purpose, motivations, logistics, and command, control and communication. It concludes with some observations about the importance of making these distinctions when formulating policy for this region.  相似文献

The economic value, social status and symbolic meaning of small arms are particular and temporal in nature. This is demonstra ted through a historical account of the dynamics of cultural change and adaptation in Nuer society. Specifically, the article shows how attitudes towards small arms shif ted over time from a positive valuation of guns as prestigious objects, to ambivalence between the need for protection and the experience of increased local lawlessness and violence. More generally, it demonstrates how weapon-rela ted activities can only be fully understood when seen against a specific cultural background. Even if the display, use and circulation of weapons appear to carry cross-cultural references, typically as expressions of power and masculine identity, the meaning is always primarily local. Therefore, strategies to reduce the destructive impact of small arms through demand side programs, based on voluntary participation, can only be carried out successfully if built on an in-depth understanding of a particular cultural context.  相似文献

NEW TERRORISM     
New or contemporary international terrorism associated with Islamic fundamentalism and the struggle against Zionism and American interests is a recent phenomenon in Kenya, different to that experienced during the struggle against colonialism. Many explanations have been offered as to why Kenya is being targeted, but have not sufficiently explored its close relationship with the West—especially Britain and the United States, the perceived connection between Israel and the former Presidency of Daniel Arap Moi, domestic forces and government policy. Externally the most important explanations for the increase in regional terrorism are the three waves of global terrorism since 1967, the most recent and significant of which is associated with Osama bin Laden and the Palestinian Intifada. These events reverberated in the region, Sudan and Somalia in particular, but also internally. Both internal and external attribution factors explain the resurgence of new terrorism in Africa. In the case of Kenya, terrorist attacks are associated with the country's internal domestic processes and a naïve approach to broader international issues.  相似文献

The Arab Spring, a pro-democracy uprising that has been sweeping through North Africa and the entire Arab world since 2010, has been described as a cataclysmic revolutionary wave that has left the overthrow of political regimes in its wake. Studies have comprehensively x-rayed the political and socio-economic circumstances that gave rise to the uprising. Apart from the impact of the uprising on political developments and democratic governance in the Arab world in particular and the world in general, the circumstances that resulted in the revolutions constitute empirical security implications for Nigeria. This is the focus of this article. Using the Ibrahim Index of African Governance (IIAG) and other selected indicators, this article draws a comparative analysis of the key factors that led to the uprisings in Egypt, Libya and Tunisia, pointing out areas of social and security tensions in Nigeria. Based on these findings, it points out the urgency of and imperative for security sector reforms in Nigeria.  相似文献

In the years since the 2003 Rose Revolution, the popularly elected leadership of the Republic of Georgia has responded to organized protests with a variety of repressive tactics. These reactions suggest that former challengers to authoritarian elites may utilize similar methods of retaining power during crisis periods. Yet, the alleged involvement of agencies of the Russian Federation in fomenting domestic instability has also occupied a central position in the national security policies of the outgoing Saakashvili government. These conditions both preceded and were reinforced by the South Ossetia War of August 2008. This article proposes a theoretical model that represents the intervening effect of interstate conflicts on state–society relations in Georgia from 2003 to present. It presents several hypotheses and possible indicators, data sources, and techniques for analyzing the interaction between characteristics of opposition groups, external threats, and the domestic security practices of contemporary Georgian political elites.  相似文献

基于信息系统体系作战问题研究的基础是作战体系构建。在对作战体系进行网络化结构分析的基础上,重点考虑体系中各类实体及属性的复杂性,根据其网络拓扑特性,以超网络、超图理论为指导,建立了基于结构层和属性层相统一的超网络模型,并结合体系作战过程中的对抗规律,提出超网络模型相应的动态演化方式,最后通过案例建模验证了超网络作战体系构建模型的适应性及优势。  相似文献

在新形势下,心理学知识与思想政治教育结合是一个必然的发展趋势。在思想政治教育中引入心理学,既尊重思想政治教育者的客观性,又有助于科学的把握教育者与被教育者互动的心理规律。思想政治教育者在开展工作中善于分析高校学生的心理健康的原因,并且能够提出解决策略。努力提高自身的综合素质,重视情感因素,通过了解学生的个体差异、从众心理、逆反心理等更好的引导学生,培养学生健全的人格和正确的思想认识方向,以实现思想政治教育的最终目标,提高当代大学生的全面素质。  相似文献
