子弹散布中心正态总体分布参数的融合估计

对带有均匀抛撒子弹头的常规导弹的命中精度评定 ,其关键在于子弹散布中心分布参数的准确估计。通常的方法由每次试验的子弹落点数据获得一个子弹散布中心 ,再由少数的几个散布中心数据、运用经典的统计方法求散布中心的正态总体分布参数 ,其不足之处在于小样本条件下采伪的概率很高。考虑到子弹散布中心只是子弹落点数据的一阶矩 ,并不能充分表达子弹落点数据所蕴含的信息量 ,而子弹落点个数远远大于导弹试验的次数 ,子弹落点所蕴含的信息比子弹散布中心所蕴含的信息要丰富得多。鉴于此 ,研究了一种子弹散布中心总体分布参数融合估计的新方法

Towards a Humanitarian Military Ethics: Moral Autonomy,Integrity and Obligations in the British and German Armed Forces

Humanitarian operations may pose challenges to which armed forces prepared for warfighting seem rather ill-equipped. It is the aim of this article to examine in what way military ethics should be adapted to humanitarian tasks. Two ideal types of military ethics are defined here: warfighting and humanitarian. The warfighting ethic is supposed to maximise the utility of the military in war and combat and to that end utilises the virtues of loyalty and honour. In contrast, humanitarian obligations require to a larger extent the development of personal integrity and an ability to follow one’s own conscience. The adaptation of military ethics is demonstrated in the case studies of the UK armed forces and the German Bundeswehr. Whereas the moral code of the UK armed forces remains anchored in the principles of the warfighting ethic, the case of the Bundeswehr presents a military ethic closely approximating the humanitarian ideal type.     

小型旋翼无人机在未来城市军事行动应用中潜力评估

随着全球范围的城市化进程不断推进,未来军事斗争向城市环境中发展是必然趋势。在城市作战需求分析的基础上,剖析了传统装备的"城市病",阐述了小型旋翼无人机在城市军事行动中的应用潜能。研究表明,针对现有装备在城市作战中显示出的若干短板,发展基于小型旋翼无人机打造侦察平台与精确打击平台将是一个较好的解决方案。而运用军民融合的发展模式挖掘小型旋翼无人机军用潜力,在提升军队作战能力,降低成本均具有积极意义。     

Defense–Growth Causality: Considerations of Regime-Switching and Time- and Country-Varying Effects

This paper develops a panel smooth transition vector autoregressive model to investigate the economic growth–defense causality. This model simultaneously resolves the estimation problems of endogeneity, heterogeneity, and nonlinearity. Empirical results support that the causality is bidirectional, nonlinear, time- and country-varying. Economic growth has a negative impact on military spending and vice versa. The larger the HDI, the smaller the negative causality. Evidently, the increase in the level of country development can reduce the negative impact of military outlays on economic growth. Reducing the ratio of military spending to GDP is beneficial for countries with low HDI scores; however, moderately increasing the share of military expenditure is favorable for countries with extremely high HDI scores. Policy authority needs to set optimal education, health, and economic development shares of GDP for purchasing a maximum economic growth rate.     

Noncognitive skills and job match: evidence from military applicants

The study examines the effect of noncognitive skills on early career choices among young job seekers. Specifically, we analyze the influence of personality traits on the decision by military applicants either to choose the military or a civilian career option. We use a unique micro-level data-set of applicants to the US Navy and exploit the fact that many individuals who initially apply for military jobs eventually choose civilian careers instead. In this institutional setting, job candidates use new information to update their beliefs about the military job match. Personality traits are viewed as productive abilities that influence applicants’ expectations about the economic return to the job and occupational training offered by the Navy. The study finds that many of the 15 lower order personality facets associated with the Big Five traits are predictive of applicants’ job choices and provides suggestive evidence of a link between personality traits, job match expectations, and career choice.
