The anchoring effect is a well-studied subject. This article connects the effect with the rules-in-use within a military intelligence institution. Particularly the rules-in-use that dictate that an analyst takes his or hers starting point from recently conducted assessments of the specific area or threat. The threat assessment as well as the written assessment were affected. The results show that officers have an aversion to lower a previous given threat assessment. This gives that to understand risk assessment we not only need to understand the methods used, we also need to understand the institutions in which they are used. This is especially relevant for military intelligence as the assessments are conducted in an environment of high uncertainty.  相似文献

This article explores whether it makes sense for national governments to employ defence industrial policies – such as offsets and discriminatory procurement practices – to support their domestic defence industries. This question has so far primarily been discussed by economists, who have argued strongly against the use of defence industrial policies. This article maintains that these economists fail to address the often complex motivation behind the introduction of these policies. It illustrates these shortcomings by contrasting their arguments against a case study of Norway, which accounts for the country’s use of defence industrial polices from the early post-Second World War era up until today. The article concludes that, depending on their objectives, defence industrial policies can be seen as either a sound security strategy or an economic fallacy.  相似文献

From the beginning of history, war has been an almost exclusively male affair and those who took part in it were often extolled as the most manliest of men. The recent feminization of the armed forces of many developed countries does not prove that women's liberation is making progress, as most people believe. Rather, it is part symptom, part cause, of the decline of those forces. Other things being equal, the fewer and less important the wars fought by any armed force the more women it has; the more women it has, the less likely it is to undertake serious wars.  相似文献

This article analyzes how the conflict environment in which a civilian monitoring mission is deployed influences the monitors' assessment of the operation. It draws on unique empirical material from the experience of the Sri Lanka Monitoring Mission (SLMM), deployed to oversee a ceasefire agreement in Sri Lanka 2002–2008. With material from a survey and in-depth interviews, experiences of the monitors are analyzed and changes over time are traced in relation to the monitors' assessment of the mandate and organizational set-up of the mission. The study points to the difficulty of monitoring missions to address escalation during an ongoing peace process. Its function is dependent on the goodwill of the parties. In essence, monitoring missions have the potential to strengthen peace when there is momentum in favor of progress, but when relations between the parties turn sour and the conflict escalates a civilian monitoring mission basically loses its potential. During the final stages of the war, which saw a very large number of civilian casualties, the war-torn areas were closed to international observers. Moreover, international pressure for a short-term ceasefire to alleviate the humanitarian situation was dismissed by the Sri Lankan government, which also saw the backing of several important actors, not the least China.  相似文献

This article presents a flexible days‐on and days‐off scheduling problem and develops an exact branch and price (B&P) algorithm to find solutions. The main objective is to minimize the size of the total workforce required to cover time‐varying demand over a planning horizon that may extend up to 12 weeks. A new aspect of the problem is the general restriction that the number of consecutive days on and the number of consecutive days off must each fall within a predefined range. Moreover, the total assignment of working days in the planning horizon cannot exceed some maximum value. In the B&P framework, the master problem is stated as a set covering‐type problem whose columns are generated iteratively by solving one of three different subproblems. The first is an implicit model, the second is a resource constrained shortest path problem, and the third is a dynamic program. Computational experiments using both real‐word and randomly generated data show that workforce reductions up to 66% are possible with highly flexible days‐on and days‐off patterns. When evaluating the performance of the three subproblems, it was found that each yielded equivalent solutions but the dynamic program proved to be significantly more efficient. © 2013 Wiley Periodicals, Inc.

This brief introduction celebrates the 20th Anniversary of the Journal, Defence and Peace Economics. Suggesting elements of an agenda for the future of this branch of economics, I raise several topics that are new and that seem to indicate that the field will expand and shift focus substantially in future years.  相似文献
