Does military expenditure increase external debt? Evidence from Asia

This article empirically explores the effect of military spending on external debt, using a sample of ten Asian countries over the years from 1990 to 2011. The Hausman’s test suggests that the random-effects model is preferable; however, both random-effects and fixed-effects models are used in this research. The empirical results show that the effect of military spending on external debt is positive, while the effects of foreign exchange reserves and of economic growth on external debt are negative. For developing countries caught in security dilemma, military expenditure often requires an increase in external debt, which may affect economic development negatively.     

Nuclear weapons and alliance institutions in the era of President Trump

The swearing in of Donald Trump as the 45th President of the United States presages, at the very least, a period of flux in American strategy with respect to the relationship between nuclear weapons and alliances. In this response to three thoughtful rejoinders to our article, “Nuclear weapons, the United States and alliances in Europe and Asia: Toward an institutional perspective,” we clarify key aspects of our argument and discuss why alliance institutions are likely to be relatively robust in the face of change, how they can influence national decision-making, and argue that they may exert a moderating influence over the new administration.

光学显微结核杆菌图像的区域分割算法

为提高结核杆菌目标的分割精度,提出了一种区域级的光学显微结核杆菌图像分割算法。通过顶帽—底帽变换增强彩色图像对比度,融合图像局部特征和全局信息计算图像梯度,利用分水岭算法实现对图像的初始分割;对分割区域采用相邻区域最大相似度准则进行合并,从而得到完整的目标区域;根据结核杆菌图像的特点,通过分析结核杆菌目标区域的颜色特性,采用多阈值分割的方法滤除区域中的杂质,实现对结核杆菌目标的分割。实验结果表明,可以分割出目标对比度低以及饱和度过低的结核杆菌目标,并且对不同染色背景的图像均能取得较好的分割结果。     

The Chinese and Asian impact on Russian nuclear policy

Asia, where nuclear powers already interact (including North Korea), exerts a growing influence on the thinking and policy underlying Russia's current and future nuclear (and overall defense) posture. China's rise is forcing Russia into a greater reliance on strategic offensive weapons and tactical nuclear weapons. These in turn will reinforce its opposition to US missile defenses, not only in Europe but also in Asia. Russia must now entertain the possibility of nuclear use in regional conflicts that would otherwise remain purely conventional. It cannot be postulated blindly that nuclear weapons serve no discernible purpose other than to deter nuclear attacks by other nuclear powers. The strategic equation in Asia and in the Russian Far East convincingly demonstrates the falsity of this approach. Nuclear weapons will be the essential component of Russia's regional defense policy if not of its overall policies – and this also includes contingencies in Europe.     

偏远严寒地区营房节能方案及经济分析

采取对比方式,利用DOE-2程序对偏远严寒地区两栋节能营房和普通营房在实测的基础上进行能耗模拟。对营房能耗水平及影响营房能耗的因素作了定量、定性的分析计算,研究在不同围护结构及换气次数下的采暖能耗。结合部队的实际条件,拟定严寒地区营房的建议方案及节能目标,并作了一定的经济性分析。结果表明,采用的节能方案基本满足节能标准的要求且经济性较好。
