How do states use nuclear weapons to achieve their goals in international politics? Nuclear weapons can influence state decisions about a range of strategic choices relating to military aggression, the scope of foreign policy objectives, and relations with allies. The article offers a theory to explain why emerging nuclear powers use nuclear weapons to facilitate different foreign policies: becoming more or less aggressive; providing additional support to allies or proxies, seeking independence from allies; or expanding the state’s goals in international politics. I argue that a state’s choices depend on the presence of severe territorial threats or an ongoing war, the presence of allies that provide for the state’s security, and whether the state is increasing in relative power. The conclusion discusses implications of the argument for our understanding of nuclear weapons and the history of proliferation, and nonproliferation policy today.  相似文献

Donald Trump’s election precipitated a debate in Australia about the value of retaining close alliance ties with the United States. Similar dynamics are discernible in other U.S. allies as the negative impact of Trump administration policies becomes clearer. Yet despite this “Trump effect,” we argue Australia is unlikely to distance itself from the United States because at the core of Australia’s strategic culture is a very positive “cultural orientation” toward the United States that is highly institutionalized in treaties, formal bilateral ties, Track 2 diplomacy, and public opinion. Such institutionalized ties have powerful path dependent effects. Accordingly, we conclude that the Trump effect does not constitute a powerful enough “exogenous shock” to move Australia off its well-worn grand-strategic path. But this alliance relationship is marked by both high cultural affinity and high institutionalization: American policy-makers should seriously consider whether other U.S. allies can tolerate similar levels of “stress.”  相似文献

Military Standard 105D has been almost universally adopted by government and private consumers for the lot-by-lot sampling inspection of product which may be inspected on a dichotomoun basis The plan specifies, for each lot size, a random sample size and set of acceptance numbers (maximum allowable number of defectives in each sample). The acceptance numbers are based upon the binomial distribution and depend upon the quality required by the purchaser. Where several consecutive lots are submitted, a shift to less severe (“reduced”) inspection or more severe (“tightened”) inspection is specified when the ongoing quality is very high or low. Further experience permits a return to normal sampling from either of these states This paper examines the long range costs of such a sampling scheme. The three inspection types are considered as three distinct Markov chains, with periodic transitions from chain to chain. The expected sample size and the expected proportion of rejected product are determined as a function of the two parameters under control of the manufacturer, lot size and product quality. Some numerical examples are given which illustrate how to compute the overall cost of sampling inspection. Suggestions are made concerning the choice of parameters to minimize this cost.  相似文献

A flexible simulation system has been designed to permit investigation of sequencing rules in a large job shop, with continual input of new work. The objective is to understand what happens rather than to find optimum rules, with many conflicting measures of effectiveness: work in process, finished goods investment, delays, machine and labor utilization, and effort to implement. A few problem areas have been explored.  相似文献

Recent research has led to several surrogate multiplier search procedures for use in a primal branch-and-bound procedure. As single constrained integer programming problems, the surrogate subproblems are also solved via branch-and-bound. This paper develops the inner play between the surrogate subproblem and the primal branch-and-bound trees which can be exploited to produce a number of computational efficiencies. Most important is a restarting procedure which precludes the need to solve numerous surrogate subproblems at each node of a primal branch-and-bound tree. Empirical evidence suggests that this procedure greatly reduces total computation time.  相似文献

ABSTRACT

The period 1833 to 1840 witnessed a brutal civil war in Spain waged between insurgent Carlists and the government Cristinos. The Carlists managed to secure reliable territorial control only over one part of Spain (upland Navarra and rural parts of the neighbouring Basque provinces). Although pockets of armed Carlism flourished elsewhere in Spain, especially in Catalonia, Aragón and Galicia, these insurgents were ineffective at coordinating actions. The Carlist court in the Basque country tried to break its strategic blockade by launching a series of expeditions into Cristino-held territory in the hope of destabilising the Madrid regime and consolidating distant insurrections. This article explains how and why these expeditions scored tactical victories but strategic failures. In particular it argues that Carlist raiding strategy was a failure, for its use of violence against real and imagined enemies in marginal and Cristino areas of control alienated civilian support.  相似文献
