Syria's slide into sectarian civil war in 2011 raises a new fundamental knowledge question about the conditions under which power-sharing pacts can be clinched as an approach to war termination. When intrastate conflicts escalate into violent sectarian struggles, power-sharing is a likely basis of an eventual political settlement in situations where partition is off the table. This article contends that there remain two puzzling knowledge gaps about power-sharing as the basis for peace agreements to end civil wars: first, the specific conditions under which elites find it in their own interest to share power with bitter adversaries rather than fight on the battlefield, and second, how war-ending elite-negotiated pacts may evolve into more enduring social contracts. These puzzles, critical for policymakers and still unresolved in the scholarly literature, suggest the need to develop more contingent- and context-specific knowledge if research findings are to more capably contribute to peacemaking efforts.  相似文献

为了找到传感器稳定性最好时的脉冲周期,对传感器检测系统进行优化,实验研究了传感器检测饮用水中大肠杆菌时,脉冲周期对传感器稳定性的影响。传感器的构成属于三电极系统,采用常规脉冲伏安法进行检测。结果显示:脉冲周期为20,40,80 ms时传感器稳定性较好,基本不会影响检测结果;脉冲周期为100 ms时稳定性很差,对检测结果有较大影响。实验表明,选择合适的脉冲周期,加以硬件和软件补偿,可以使传感器获得较好的稳定性。  相似文献

From the Editors     
Israel's policy of military reprisals has never seemed to follow any consistent pattern of tit‐for‐tat. On the one hand, not every violent incident was answered with a counterattack. On the other hand, when Israel responded, frequently it employed an excessive amount of force, which was disproportional to the Arab provocation. This behavior has not been the consequence of a premeditated and rational strategy. Instead, it appears to have been the result of a political dispute between alternative approaches regarding the use of military force. The following research analyzes the development of this controversy and how these differences of opinion were resolved.  相似文献

This article examines Edward Lansdale's return to South Vietnam during the Johnson administration. Lansdale offered a persuasive critique of the mistakes the American policy in Vietnam, but his potential influence was severely limited by a combination of bureaucratic infighting in Saigon and a general indifference to the political aspects of the conflict in Washington. While Lansdale was unable to signiflcantly influence the policies of the Johnson administration, his experience in Saigon during 1965–68 offers historians a unique perspective on many facets of American and South Vietnamese policymaking during a crucial period of the Vietnam War.  相似文献

Under what conditions can leaders achieve wartime political–military integration? In the Vietnam War, political–military integration exhibited dramatic variation: in the air war, the US was able to tightly integrate its political objectives and military conduct, but in the ground war, the American military prosecuted a strategy that was both divorced from broader political objectives and was immune from Washington's influence. I argue that the nature of information management between the military and civilian leadership explains the pattern of political–military integration in the Vietnam War more completely than do explanations that focus on the organizational cultures of professional militaries.  相似文献
