This paper considers the contribution of military publishing to the nineteenth-century military revolution leading to the Great War. The subject is addressed in four contexts. The first is informational, analyzing the role of military publications in making available data and ideas that increased military effectiveness. The second is syncretic, evaluating the effect of military publications on cohesion within increasingly large, complex armies, and between armies and their societies. The third is internal. It discusses the contributions to professional insecurity generated by print, and by its electronic extensions the telegraph and the telephone. Finally, the paper considers the print revolution's influence on actual war-fighting  相似文献

Chinese writings on the workings of nuclear stability, deterrence, and coercion are thin and politicized. Nevertheless, it is possible to glean, from direct and inferential evidence, rather pessimistic conclusions regarding Chinese views of nuclear stability at low numbers. While China has been living with low numbers in its own arsenal for decades, today it views missile defense and advanced conventional weapons as the primary threat to nuclear stability. More generally, China views nuclear stability as wedded to political amity. Because none of these would be directly addressed through further US and Russian arsenal reductions, China is unlikely to view such reductions as particularly stabilizing. While there is little in Chinese writing to suggest lower US and Russian numbers would encourage a “race to parity,” there are grounds to worry about China becoming more assertive as it gains confidence in Beijing's own increasingly secure second-strike forces.  相似文献

For many years, non-nuclear weapons states have sought binding commitments from nuclear armed states that they would not be the victim of either the threat or use of nuclear weapons—so-called negative security assurances (NSAs). The nuclear weapon states have traditionally resisted granting such unconditional NSAs. Recent U.S. efforts to use nuclear deterrence against the acquisition and use by other states of chemical, biological and radiological weapons, however, have further exacerbated this divide. This article analyzes the historical development of NSAs and contrasts U.S. commitments not to use nuclear weapons with the empirical realities of current U.S. nuclear weapons employment doctrines. The authors conclude that NSAs are most likely to be issued as unilateral declarations and that such pledges are the worst possible manner in which to handle the issue of security assurance.  相似文献

This article explores the challenges that Australia faces in reconciling its commitments to nonproliferation and uranium exports during a time when the international nuclear nonproliferation regime is under major stress and the world uranium market is bullish. The “grand bargain” that has framed Australian participation in the nonproliferation regime and the nuclear fuel market since the 1970s was only tenable in an era of stagnant uranium demand and a stable nuclear balance. However, contemporary nuclear proliferation dynamics and the revival of interest in nuclear energy have accentuated the incompatibility between Australia's commitment to nonproliferation and the desire to profit from uranium exports. The contemporary international strategic environment, international nonproliferation regime, and nuclear energy market are characterized by developments that not only undermine the basis of Australia's grand bargain, but also present challenges and opportunities for the refashioning of Australian policy.  相似文献

We examine several methods for evaluating resource acquisition decisions under uncertainty. Traditional methods may underestimate equipment benefit when part of this benefit comes from decision flexibility. We develop a new, practical method for resource planning under uncertainty, and show that this approach is more accurate than several commonly used methods. We successfully applied our approach to an investment problem faced by a major firm in the aviation information industry. Our recommendations were accepted and resulted in estimated annual savings in excess of $1 million (US). © 2003 Wiley Periodicals, Inc. Naval Research Logistics, 2003  相似文献

We consider a bivariate Pareto distribution, as a generalization of the Lindley-Singpurwalla model, by incorporating the influence of the operating conditions on a two-component dependent system. The properties of the model and its applications to reliability analysis are discussed. © 1993 John Wiley & Sons, Inc.  相似文献
