When Do Imposed Economic Sanctions Work? A Critical Review of the Sanctions Effectiveness Literature

ABSTRACT

There is growing policy consensus in Washington and other Western capitals that economic sanctions are powerful tools to cope with major foreign policy crises. Are sanctions, particularly targeted sanctions, really the potent instruments optimists suggest? Under what circumstances do punitive economic measures induce policy change in sanctioned countries? To probe these queries, in this article I outline the conditions that have been identified as more likely to lead to successful sanctions outcomes in the literature. I also discuss four major shortcomings of existing scholarship. First, the sender-biased interpretation of sanctions effectiveness renders the treatment of the ‘ineffective’ cases with negative outcomes the same as those cases that induce no discernable change in target behavior. Second, the prevalent use of static data from existing sanctions databases reduces the ability of researchers to study various time-specific factors affecting the probability of sanctions success. Third, the dominant state-centric bargaining model in the literature offers limited insight into contemporary coercive measures directed at non-state actors. Fourth, the study of sanctions in isolation of other instruments that frequently accompany them, such as incentives and diplomatic pressure, leads to a partial understanding of the specific role sanctions play in shaping the outcome of key foreign policy initiatives.     

The long and winding road … to success? Unit peace operation effectiveness and its effect on mission success

Why does peacekeeping sometimes fail? How can effective peacekeepers increase the likelihood of success of a mission? The two main flaws in the current evaluations of peace operations are that they mainly rely on already concluded missions and that they make use of indicators that do not reveal micro-level dynamics. This article introduces an analytical framework relating the effectiveness of soldiers to their actual impact in their area of operation in a peace operation. The framework is called “unit peace operation effectiveness” (UPOE). Focusing on soldiers in peace operations, this article shows that: different units behave differently; emphasize different aspects of the mandate; and are effective in different ways. Ultimately, this has an actual impact on the end-state of the mission. It relies on and adapts classic security studies works to theoretically enrich the peacekeeping literature. The model is tested in an illustrative case study based on ethnographic work on French and Italian units in Afghanistan between 2008 and 2010.

Zodiac算法新的不可能差分攻击

重新评估了Zodiac算法抵抗不可能差分攻击的能力。通过分析Zodiac算法的线性层,给出了Zodiac算法两条新的14轮不可能差分。利用新的不可能差分,结合Early-Abort技术对完整16轮的Zodiac算法进行了不可能差分攻击。攻击过程中一共恢复6个字节的密钥,其时间复杂度只有2_32.6次加密,数据复杂度约为2_85.6个明文,该攻击结果与已有最好的结果相比,时间复杂度降低了一个因子2₃₃。结果表明由于Zodiac算法线性层的扩散性差,使得该算法对不可能差分分析是不免疫的。
