The Problem of Weak Nuclear States

Governments are increasingly recognizing the problem posed by internally weak nuclear-capable states. The problem, however, is under-theorized. This article brings together literature on sovereignty and international order, the nonproliferation regime, and weak states, and introduces new concepts to provide a more structured understanding of this problem. Insight comes from focusing attention on the function and governance of two nuclear estates (termed the production and operational estates), and on their resilience to decay and disorder occurring within the state and society. Drawing on empirical observation, the authors suggest a typology of weakness in nuclear states, involving state fragmentation typified by the former Soviet Union, the “hard weak state” typified by North Korea, and the internally conflicted state typified by Pakistan. Although these types give rise to distinctive difficulties, their alleviation depends heavily on the maintenance of internal authority within the state and estates, the presence or absence of cooperative relations, and the international regulatory framework's vitality.

色空间对HDRI亮度测量方法的影响

相机内置预处理环节中的白平衡、色度空间转换是数码成像过程中的重要环节,sRGB和Adobe RGB是数码相机2种常用的色空间.为进一步研究色空间对HDRI亮度测量方法的影响,在荧光灯照明的实验室,分别利用sRGB和Adobe RGB色空间对色板成像,测量该亮度测量方法中各色板的标定因数,计算各色板标定因数的相对不确定度.实验结果表明:2种不同色空间获得的标定因数不同,且Adobe RGB色空间标定因数相对不确定度的平均值小于sRGB色空间的;色空间改变后,标定因数需要重新进行标定,且优先选用色域较宽的Adobe RGB色空间.     

Trinitarian troubles: governmental,military, and societal explanations for post-1945 Western failures in asymmetric conflicts

It seems paradoxical that powerful Western states are at their most vulnerable when the disparity in military capabilities between them and their opponents is at its largest. Yet it is precisely in such ‘asymmetric conflicts’ that Western countries have failed to achieve their overall political objectives the most often. Focusing on the post-1945 world, this article will examine governmental, military, and societal reasons for Western failures in asymmetric conflicts. Politicians' lack of understanding regarding war's fundamental nature, militaries' tendency to dissociate operational goals from grand strategy objectives and citizens' moral aversion to warfare appear to be among the main obstacles to success.
