火力分配环协同度的编队反导决策优化

舰艇编队协同反导决策是一个多阶段多目标的决策系统,依据模糊权距离和隶属度概念,考虑系统中各阶段的协同关系,提出基于火力分配环协同度的概念,将模糊优选理论与动态规划原理有机地结合起来,寻求基于舰艇编队协同反导的多阶段多目标优化的最优均衡策略,并应用于解决舰艇编队协同反导决策的优化中,得出了具有指导意义的结论。     

两栖作战舰机协同防空指挥协同网与指挥关系网

为了解决提高航母编队防空作战效能的问题,运用决策树方法分析航母编队防空作战指挥网是一种新方法。先分析航母编队的指挥机构,分析决策群指、作战平台与任务之间的关系。描述了编队协同网和编队指挥关系网,建立了编队指挥关系网的数学模型,采用决策树方法求解该数学模型,给出了编队指挥关系网的设计算法,通过实例分析了算法的计算过程,对结果进行输出。结论:预警机与远程巡逻机战术群是指挥关系网的最高决策点。这些工作为设计和优化航母编队舰机协同防空作战指挥网提供了一定的理论基础。     

Comprehensive approaches,diverse coherences: the different levels of policy coherence in the Dutch 3D approach in Afghanistan

Since 2000, international organisations such as the UN, NATO and the EU, but also countries, have started to apply what has been called the comprehensive approach to crisis management. This article unpacks this comprehensive approach implemented by the Dutch in Uruzgan province, Afghanistan. It first borrows and expands a conceptual framework developed by De Coning and Friis. Subsequently, it maps the different sorts of coherence in the mission by applying the framework. It shows how in practice there was not one single comprehensive approach, but many different forms of interaction between a number of organisational units. Each interaction had its own distinct issues and its own level of coherence. The level of coherence differed depending on the level at which the interaction took place – strategic at headquarters level versus operational at field level – and at what point in the mission it happened – in most cases it moved towards more cohesion.     

Country Survey XIII: Japan's security posture and defense industry prospects

Defense budgets in Japan have been complicated compromises from numerous inputs ‐ including threat perceptions, domestic industrial/technological base development, support for the bilateral security treaty with the United States and internal bureaucratic politics ‐ but with the fall of the former Soviet Union, the clearest justification for higher spending disappeared. Double‐digit defense spending increases that were common in the 1980s have been replaced by annual increases lower than present inflation rates, resulting in negative real growth in the country's defense budget. Domestic economic problems and consistent government pressures for smaller budgets have further slowed annual growth in total spending and have contributed to lower procurement budgets. As a result, the domestic Japanese defense industry is facing far more constrained conditions from the growth years of a decade before.

Government policymakers are examining Japan's regional security environment as well as its alliance with the United States to determine the appropriate course for the country to take in the coming years. The formal security treaty with the United States is likely to remain a major element of government positions, but other aspects of the country's overall security posture are open to debate. Perceptions of a reduced threat environment are fueling additional pressures for defense budget cuts.

The domestic defense industry seeks means to assure its survival in domestic defense markets in this constrained environment. Expansion into overseas markets to offset declining domestic markets is an option that currently is constrained by policy restrictions on arms exports. Industry is advocating re‐examination of those policies and unlike earlier years, government appears willing to respond positively but cautiously to this lobbying.     

SWAZILAND

The election of Sheik Sharif Sheik Ahmed as the transitional president of Somalia was the climax of the United Nations (UN)-led Djibouti peace process. The election, it was hoped, would herald the beginning of the reconstitution of the Somalian state. Unfortunately, nearly three years after the event, that has still not happened. The government of Sheik Sharif has faced a number of challenges which are yet to be resolved. In the end, the Djibouti peace process has not guaranteed a stable and functional national government in Somalia.     

EDITOR'S NOTE

The Nonproliferation Review (NPR) recently interviewed Ambassador Sergio de Queiroz Duarte of Brazil, who presided over the 2005 Seventh Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Ambassador Duarte discussed his views on the outcome of the conference and the future of the treaty. He provided NPR with valuable insights into the outcome of the conference and also shared his thoughts on some of the most pressing issues confronting the NPT today, including the Middle East, nuclear terrorism, elimination of the threat of highly enriched uranium in the civilian nuclear sector, proposals to limit access to the nuclear fuel cycle, nuclear disarmament, and negative security assurances. Blaming the failed conference on a general lack of political commitment among states parties and their unwillingness to negotiate common solutions, Ambassador Duarte stressed that “the conference should face squarely its own failure without my attempting to disguise or sugarcoat the deep differences of view, which must be resolved with courage and determination by the states parties if they want the treaty to remain effective.”?He emphasized that if states fail to act on their overriding interest in upholding the NPT, especially if states parties continue to ignore or disregard their nonproliferation and nuclear disarmament obligations, some states might come to believe that their security interests are no longer served by the treaty. The future prospects of the NPT would then “look dire indeed.”     

Beyond Iran: Containing Nuclear Development in the Middle East

ABSTRACT

Several states in the Middle East have noted their interest in nuclear energy programs, but current cost and timeline estimates understate the difficulties that these states will face. A state-level analysis of nuclear development capacities in Saudi Arabia, Egypt, Jordan, Turkey, and the United Arab Emirates suggests that building nuclear infrastructure in the region will, in fact, be a lengthy and expensive endeavor, due to concerns such as export constraints, public opposition, a lack of human resources, and high overhead costs. This has implications for nuclear weapon nonproliferation: first, fears that these developing nuclear energy capabilities may facilitate possible weapon proliferation are premature, and second, there is time to ensure that any burgeoning nuclear infrastructure in the region remains safe and civilian in nature.     

GENDER AND ATTITUDES TOWARD PROFESSIONAL ETHICS

This study was designed to examine the influence of gender and age on attitudes toward professional ethics among a sample of the Nigeria police officers. Using a cross-sectional survey, data was collected from a total of 163 participants. Results revealed that gender and age were significant predictors of unethical beliefs; female and older police participants were also more ethical than their male and younger counterparts. These findings were discussed in the context of socialization theory, Gilligan's moral development theory and other organisational practices, while its practical implications for the recruitment, selection and placement in the Nigeria police were also emphasized.     

ADVANCING THE GOALS OF NPT ARTICLE VI

International technical cooperation on issues relevant to the challenges of nuclear disarmament can demonstrate commitment to obligations under Article VI of the Treaty on the Non-Proliferation of Nuclear Weapons, strengthen the security of fissile materials and weapons, and develop technical approaches to support more ambitious disarmament activities in the future. Including non-nuclear weapon states would ensure that their views are taken into account and would invest them in developing solutions to key challenges. This article discusses three areas for technical cooperation that would build on past activities and that could produce such benefits as improved protection, control, and accounting of nuclear weapons and fissile material; enhanced transparency for nuclear weapon complexes; and mechanisms for international management of sensitive civilian nuclear facilities. International cooperation in each of these areas could provide a technical basis for pursuing possible future disarmament negotiations and substantively demonstrate commitment to Article VI.
