ABSTRACTInternational Organisations (IOs) are crucial actors in spearheading the global adoption of anti-money-laundering (AML) legislation. However, the extent to which AML legislation has been implemented in Zimbabwe under the aegis of the Financial Action Task Force (FATF) and East Africa and Southern Africa Money Laundering Group (ESSAMALG) may put the efficacy of legislation passed at the behest of IOs into question. This article suggests that glocalisation may enhance the international fight against money-laundering. That is to say, international standards should be applied domestically with due regard for local legislative environment. 相似文献

The Western European defence industry used to be characterized by numerous constraints, especially in the small countries, subject to uneconomic defence production policies. It faces, since the end of the Cold War, a succession of new challenges such as budget restrictions, armament reductions and geopolitical upheavals. The EU is pushing in the direction of a cohesive foreign policy, including security and defence. Today, the emergence of a more consolidated European defence industry and the presence of oligopolistic European companies imply the definition of new roles for the EU and for its European Security and Defence Policy (ESDP). The solution is not protectionism, but more co‐operation to ensure effective defence production at a socially acceptable cost. In the framework of this co‐operation, defence companies in small and medium countries have a role to play as part of the supply chain to major weapon system integrators. 相似文献

This paper is intended to complement the existing literature on civil wars. First, it presents a simple theoretical model of conflict that defines a two‐sector economy. In a contested sector, two agents struggle to appropriate the maximum possible fraction of a contestable output. In an uncontested sector, they hold secure property rights over the production of some goods. Agents split their resource endowment between ‘butter’, ‘guns’ and ‘ice‐cream’. Following the theoretical insights the empirical analysis focuses on the relationship between civil wars and different sectors of the economy. In particular, a panel probit specification shows that the incidence of a civil war decreases in the size of manufacturing sector. 相似文献

This article examines the relationship between defence expenditure and economic performance in South Africa, both prior to and after that country's first fully democratic election in 1994. Prior to 1994 defence expenditure decisions were largely dominated by non‐economic factors; since then defence spending has declined in reaction to, inter alia, the need to address a number of socio‐economic inequities. After 1975 in particular, military industrialisation in South Africa placed a disproportionately high burden on the country's industrial resources and natural economic and technical capabilities. However, although this suggests that the opportunity cost of domestic arms production has been fairly high, the country's poor economic and development performance since the mid‐1970s is a function of underlying structural deficiencies and institutional constraints rather than the consequence of inordinately high defence spending levels. 相似文献

We revisit the causal relationship between military spending and unemployment in the G7 countries applying a bootstrap panel causality analysis that accounts for both cross-sectional dependence and for heterogeneity across countries. Using per capita real GDP as a controlled variable, we found a unidirectional causality running from military spending to unemployment for Canada, Japan, and the US, one-way causality running from unemployment to military spending for France and Germany, and bidirectional causality for Italy and the UK. The empirical evidence does not seem to provide consistent results regarding the causal relationship between military spending and unemployment in G7 countries. 相似文献

针对现有指控系统由于功能模块化设计导致模块间耦合性强、复用性差,系统开发效率低以及升级困难等问题,分析了应用CORBA构件模型(CCM)开发指控系统软件的可行性,建立了CCM构件与分布式中间件集成模板框架,并以WorkBench开发环境为例,给出了应用CCM进行指控系统构件开发、打包、部署等具体实现过程.实际应用表明:CCM在指控系统的有效应用,能够实现系统基于可重用构件设计的开发,不仅提高了系统灵活性、重用性和可配置性,而且简化了系统开发流程,缩短了开发周期,降低了开发成本. 相似文献

针对多传感器目标识别的群决策问题,考虑到多目标威胁程度评价指标属性的模糊性,首先将多传感器目标评价属性的定量、定性描述指标统一转化为三角模糊数,充分利用三角模糊数性质构建群决策函数,实现定量指标与定性指标的规范化处理,在此基础上提出一种基于加权矩阵排序的三角模糊数多传感器目标识别的群决策算法,实现对多传感器目标的威胁程度的综合评估.最后,通过多传感器目标评估实例分析并证明了算法的可行性和有效性.同时实验发现该算法对于多属性、多评价者的群体决策具有优势,且不易受外界参数变化的影响. 相似文献
