This paper empirically investigates the importance of financial and political variables in determining debt rescheduling probabilities in Turkey for 1955–2000. The problem of sovereign debt default and rescheduling has been the subject of substantial academic research during the last two decades. There has been criticism of models of developing countries’ indebtedness and rescheduling that rely solely on some economic or financial predictors related to country debt, the foreign exchange sector or the domestic economic situation. Using probit analysis, this paper indicates that financial variables are important determinants of rescheduling probabilities. However, political variables are not significant in our models.  相似文献

大中口径舰炮敏捷供弹系统虚拟样机仿真研究   总被引:2,自引:0,他引:2  
文中提出了一套完整的大中口径舰炮敏捷供弹系统。应用三维实体建模软件PRO/E完成了整个供弹系统各个子系统的模型设计及建立;进行了装配检查,排除了零部件之间的干涉,完善了零部件设计;再利用PRO/E和ADAMS相结合,建立供弹系统各部分的驱动系统,并与实体模型结合,对此系统进行机构的运动学、动力学和驱动系统仿真,对设计的可行性和合理性进行深入研究.通过以上研究,建立了一个完整的大中口径舰炮敏捷供弹系统虚拟样机,为供弹系统的进一步深入研究以及实际生产提供了坚实的基础,同时给军械设计提供了一条高效率、低成本的设计方法.  相似文献

In this study, a laminated woven bamboo/woven E glass/unsaturated polyester composite is developed to combat a ballistic impact from bullet under shooting test. The aim of this study is to understand the fundamental effects of the woven bamboo arrangement towards increasing ballistic resistance properties. The work focusses on the ballistic limit test known as NIJ V50, which qualifies materials to be registered for use in combat armor panels. The results show that the composites withstood 482.5 m/s ± 5 limit of bullet velocity, satisfying the NIJ test at level II. The findings give a strong sound basis decision to engineers whether or not green composites are qualified to replace synthetic composites in certain engineering applications.  相似文献

The Soviet Union was able to develop a large military-industrial complex and become the world's second superpower despite deficiencies in its centrally planned economy because defence was given high priority status and special planning, rationing and administrative mechanisms were used to attain national security objectives. However, in the period 1976-85 the effectiveness of priority protection diminished and defence institutions experienced more of the problems typical of the shortage economic system. The heavy defence burden also created growing difficulties for the civilian economy. The attempts by the Gorbachev government to reform the defence sector and improve defence-economic relationships during perestroika (1985-91) uniformly failed. For most of the transition period, the Russian military-industrial complex has been adversely affected by its low priority status, cuts in defence spending, instability of the hybrid politico-economic system, and negative growth of the economy. The armed forces and defence industry have been reduced in size and their outputs of military services and equipment have fallen to low levels. Nevertheless, the Russian armed forces still have over one million troops, significant stocks of sophisticated conventional weapons, and a large nuclear arsenal. The government of President Putin has raised the priority of the defence sector, increased real defence spending, and adopted ambitious plans to revive Russian military power. It is likely, though, that tight resource constraints will hamper efforts to reform the armed forces and to upgrade weapons. By 2010 Russia will be an important, but not dominant, military power in Eurasia.  相似文献

当前,对官兵进行情商培育要从以下几方面入手:更新观念,确立大智力观的人才培养目标;统筹规划,重视官兵情感教育与部队思想政治工作的结合渗透;以人为本,构建具有情感特性的军事训练模式;与时俱进,建立“二元化”的军事人才评价体系。  相似文献

The defense‐growth nexus is investigated empirically using time series data for the US and allowing the effect of defense spending on growth to be non‐linear. Using recently developed econometric methods involving threshold regressions, evidence of a level‐dependent effect of military expenditure on GDP growth is found: the positive externality effect of defense spending prevails for relatively lower levels of defense spending (with respect to the history of defense spending in the US) and reverts its influence for higher levels.  相似文献
