Defense Spending and Unemployment in France

France has received little attention in the literature of defense economics, despite some outstanding features of the country’s situation. This study attempts to partially fill this gap with new empirical evidence which evaluates the influence of military expenditure on the unemployment rate between 1975 and 2008. Our estimation is based on the ARDL approach to cointegration. The results reveal that both defense and non-defense spending exert a negative influence on unemployment but that defense spending has a higher negative impact.

Damage assessment of the target area of the island/reef under the attack of missile warhead

Under the background of vigorously developing facilities of island/reef in the world, the economic value and strategic significance of the island/reef have become increasingly important. Unfortunately, they may easily become the attacking target of missiles in the war time. Therefore, aiming at the damage quantification of the targets in the island/reef under the missile attacking, a macroscopic damage assessment model for the target area is proposed in this paper. The model focuses on the construction of the assessment model framework. Firstly, the analytic hierarchy process and the grey relational analysis are applied to measure the importance of each target in the region through four indicators of the target hazard, striking urgency, damage advantage and mission relevance, respectively. Secondly, based on the damage mechanism of shock wave and fragments to target, the corresponding damage model is established, and the damage grade of each target in the evaluated area is obtained according to the damage criteria and grading standard. Finally, the model obtains the overall damage grade of the target area by employing the fuzzy comprehensive evaluation method, with synthesizing the importance and the damage grade of each target. Through the verification of an example, it demonstrates the certain feasibility of the model and provides a certain basis and reference for the subsequent research.     

The Gravity of Arms

The aim of this paper is to investigate the determinants of international arms transfers in a gravity model framework. By distinguishing between the decision to export arms (extensive margin) and the value of the arms exported (intensive margin), while also considering its interdependence, is what differentiates this paper from previous research. A theoretically justified gravity model of trade augmented with political and security motives is estimated using a two-stage panel data approach for 104 exporting countries over the period from 1950 to 2007. In addition to the usual gravity variables related to the economic mass of the trading countries and the trade cost factors, the model is extended with political and security factors. The level of democracy in both trading partners, political differences between trading partners and voting similarity with the United States in the UN General Assembly of the countries engaged in trade are the main political factors, whereas the existence of conflicts, military pacts, and embargoes are taken as security motives. The key result indicates that both political and security motives are an important determinant of an arms trade, but their effects on the extensive margin of exports (the decision to order a transfer) differs from their effect on the intensive margin (average value of exports). Moreover, the relative importance of the factors under study has changed since 1989. In the post-cold war period, countries that are less democratic are more likely to export arms, military pacts are less relevant and embargoes play a role.     

非均匀湍流场中螺旋桨噪声研究

针对螺旋桨在湍流中的非定常噪声问题,在均匀湍流下螺旋桨宽频噪声相关性法的基础上,推导了非均匀湍流下螺旋桨宽频噪声的公式。在均匀湍流的研究中使用了十桨叶螺旋桨模型,并将计算结果与试验数据进行了对比,发现吻合较好。对于非均匀湍流中的问题,研究发现湍流的不均匀程度不会对宽频谱波峰的位置产生影响,噪声谱波峰的位置仍然取决于叶频,湍流的不均匀程度只会改变叶频处的波峰高度。最后研究了均匀湍流和非均匀湍流中侧斜角对螺旋桨噪声的影响,发现桨叶侧斜角的存在会降低螺旋桨在湍流中受到的宽频噪声。     

Coordination as showcasing: the establishment of Norway’s Afghanistan Forum

In complex operations such as the interventions in Iraq and Afghanistan, where multiple government ministries are involved in putting together a state’s contributions, the use of national-level coordination bodies has become more widespread. Research has taken for granted that the rationale behind these bodies reflects their declared aim – enhanced coordination as a means to improve mission effectiveness. However, they appear to have had modest effect on coordination. That notwithstanding, they seem to remain popular. This prompts us to ask why such bodies are actually established. This article – based on in-depth interviews and archival records – critically explores the establishment of Norway’s ad hoc, inter-ministerial, political-level Afghanistan Forum. Distinguishing between a structural-instrumental, a cultural-institutional and an environmental perspective from organizational theory to structure the analysis, this article shows that the declared purpose of the forum, inter-ministerial coordination, proved less important than showcasing coordination efforts and keeping the coalition together. In addition, national traditions in handling coordination challenges in the central government apparatus and powerful international reforms helped bring the forum about. This has implications for research on the rationale and effectiveness of these bodies, and also for understanding their policy relevance.     

在新时代对培育大学生综合国防素质的思考

综合国防素质是在适应世界军事变革发展和国家安全新需要的基础上,对传统国防素质的一次改进与提升。与传统国防素质不同,综合国防素质强调的是对综合国防意识、综合国防知识以及综合国防技能的掌握和运用。新时代,弘扬和培育大学生综合国防素质是贯彻党的十九大精神、落实国家教育事业"十三五"规划部署的重要举措,对加快实施人才强国战略、实现新时代强军目标发挥着重要作用。
