Why should deployment affect re‐enlistment? In our model, members enter the military with naïve beliefs about deployment and use actual deployment experience to update their beliefs and revise their expected utility of re‐enlisting. Empirically, re‐enlistment is related to the type and number of deployments, consistent with the learning model. Non‐hostile deployment increases first‐term re‐enlistment but hostile deployment has little effect except for the Army, where the effect is positive. Both types increase second‐term re‐enlistment. Interestingly, first‐term members with dependants tend to respond to deployment like second‐term members. In addition, deployment acts directly to affect re‐enlistment, not indirectly through time to promotion.  相似文献

Post-Cold War “lab-to-lab” collaborations on unclassified scientific issues between U.S. and Russian nuclear weapons laboratories set the stage for bilateral cooperation in materials control and other nuclear areas. They also became the major element in a cooperative process initiated by a Presidential Decision Directive to ensure Russia's compliance with the Comprehensive Nuclear-Test-Ban Treaty. These collaborations have always been highly favored by leaders of the Russian nuclear weapons complex—the same leaders who oversee Russia's participation in various government-to-government programs. This article reviews these collaborations and examines the possibility that U.S. rebuffs of Russian proposals and the U.S. failure to keep promises of expanded collaboration could contribute to Russia's reluctance in major programs and even lead to a return to nuclear testing by Russia. The author argues that a renewed U.S. commitment to the process should be an immediate goal of the Obama administration and is an essential step in re-engaging Russia to solve the nuclear problems remaining from the Cold War. Steps for doing so are recommended.  相似文献

ABSTRACT

The recent use of chemicals in warfare in Syria and Iraq illustrates that, despite the important work of the 1997 Chemical Weapons Convention (CWC), the world has not yet been totally successful in stopping the use of indiscriminate toxic agents in conflicts, either by states or non-state actors. Michael Crowley's excellent and timely new book, Chemical Control, analyzes the use of “riot control agents” (RCAs) and “incapacitating chemical agents” (ICAs), including launch and dispersal systems, by police, paramilitary, and military forces over the last decades and raises the challenging question about where the red line might be drawn between banned and permitted uses of chemicals. He discusses this problem not only in the context of the CWC, which allows use of RCAs for civilian riot control, but also in the context of international law, human rights, and criminal justice, including the Biological and Toxin Weapons Convention and other disarmament and abolition regimes. He proposes a “holistic, three-stage approach” to addressing this issue “for effective regulation or prohibition of the weapon or weapon-related technology of concern.” As we approach the global abolition of a whole class of weapons of mass destruction in the next decade or even sooner, Chemical Control is helpful in better understanding and solving the dilemma of what's actually banned or permitted under international law, and precluding states undermining the chemical weapons ban.  相似文献

Strategic terrorism: The framework and its fallacies   总被引:1,自引:0,他引:1  
This article seeks to lay out a comprehensive framework by which those who utilize a campaign of strategic terrorism seek to attain their ends. It identifies a distinctive modus operandi: 1) disorientation: to alienate the authorities from their citizens, reducing the government to impotence in the eyes of the population; 2) target response: to induce a target to respond in a manner that is favorable to the insurgent cause; 3) gaining legitimacy: to exploit the emotional impact of the violence to insert an alternative political message. By elucidating the strategy of terrorism, the analysis also reveals its inherent limitations. Resting on the premise that a militarily more powerful adversary will in some way feel restrained from bringing the full force of its military superiority to bear, the strategy relies exclusively on the exploitation of the psychological effects of armed action, thereby rendering it vulnerable to those who are willing to view the resolution of clashes of interest principally in terms of the tangibles of military power.  相似文献
