Guinea-Bissau's transition toward democracy has been violent and disruptive. Despite holding elections and attempts to promote economic and social development, the latest government, under President Yala, is not equipped to bring stability or even a more democratic state. A politicised military, inexperienced opposition and corrupt government officials have contributed to the current poverty and instability. Although unlikely to be deposed by the fragmented opposition, Yala is not secure within his own party and is likely to use his position to weaken his opponents. As a Catholic, Yala has been careful to avoid religious conflict by reassuring Muslim citizens that they will not be marginalised. The economy is precarious and poverty has not been addressed. Guinea-Bissau is dependent on foreign donors for its financial needs. Guinea-Bissau has begun military operations against rebels opposing the Senegalese government and the battles seem likely to continue to cause regional instability. Without external intervention political and economic development looks remote. 相似文献

The armed conflict in the DRC has been characterised by appalling, widespread and systematic human rights violations. It varies from civil war to a war between national armies. Much of the conflict falls between these two categories due to the involvement of foreign troops in civil strife, as well as foreign rebel groups fighting their home government's troops but on Congolese soil. The most pressing need is to cease hostilities and address the humanitarian situation in the country. Questions of justice and accountability, and issues relating to the rule of law will have to be addressed soon in order to achieve a durable peace in the country and in the region. Since there are links between different conflicts in the region, a broader solution should preferably be found. However, this would further complicate an already difficult proposition. Efforts limited to the DRC would be more feasible and could lead to similar measures in other conflict ridden countries in the region. This essay therefore discusses the available processes for justice. 相似文献

针对现有一些顺序输送混油计算公式中存在的问题,在κ-ε紊流模型和使用壁面函数法处理近壁区问题的理论基础上,提出了顺序输送混油新的模型,并利用PHOENICS软件成功地对该模型进行了数值求解.且首次以图像的形式直观地显示出管内的混油浓度分布,并通过浓度曲线的对比,对油品输送次序对混油的影响进行了分析.研究结果表明:计算机模拟能够为顺序输送混油机理的研究提供一个较为准确而便利的手段.同时也对影响混油的其他一些因素(高差、阀件、温度等)的研究提供了参考与帮助. 相似文献
