Military support and transnational terrorism

Analysing the relationship between the provision of military support and the probability of becoming the target of a terrorist attack, this paper contributes to the literature on the causes of transnational terrorism. We find that deployment of military troops of country X in country Y increases the probability of a terrorist attack on citizens of country X by a terrorist group located in country Y. Exporting weapons to country Y seems to increase the probability of being attacked by the terrorists of this country Y as well. Deploying materials, however, does not seem to significantly influence the probability of attack. Including lagged values for our military support variables ensures that the causality direction is from military support to terrorist attacks. Moreover, these results indicate that while the effect of military deployment on the probability of attack lasts for more than 1 year, the effect is rather short-lived.

忆郭化若中将两谈中央苏区第一次反"围剿"

上世纪70年代,江西永丰县龙岗为筹办中央苏区第一次反"围剿"陈列馆,笔者受命征集各种口碑资料,两次专程拜访我党军事理论家和军事教育家郭化若中将,因他当年在毛泽东、朱德身边工作,任红军总部参谋处长兼作战科长,草拟第一、第二、第三次反"围剿"作战命令,是战役指挥的高层亲历者,便请他追忆当年在赣南山区与国民党军周旋的所见所闻.     

论中国战略文化的近代流变

中华“天下观”把和谐的天下秩序作为基本的价值追求,并由此形成了求和平、谋统一、重防御的中国战略文化传统。近代以来,在西方“强权即是公理”的战略文化冲击下,为了实现救亡图存的历史使命,中国战略文化实现了文化革新,但其基本价值观念没有变,至今仍然影响着中国的对外战略选择。     

Military deployment and international terrorism: do location and mission type matter?

Extant literature documents a relationship between military deployment and the risk of an international terrorist attack against citizens of the deploying country. It appears that deployment significantly increases the possibility of terrorist actions in the home country. In particular, if country A decides to send troops to nation B, then citizens of the former country are more likely to fall victim of an attack carried out by a terrorist organisation originating from the latter country. Contributing to this line of literature, we further refine this relationship by distinguishing between regions where the troops are sent as well as by introducing differences between types of deployment. Our results indicate that missions to Asia and the Middle East are more dangerous than missions to other regions as reflected by the terrorist threat in the home country. Robustness tests do however show that the significance of the location variable Asia is predominantly attributed to the mission to Afghanistan. As for types of deployment, only ad hoc missions seem to increase the risk of an attack, whereas no significant results are found for other missions such as operations under UN and NATO flag. Leaving out the missions to Iraq and Afghanistan however also increases the danger resulting from missions by fixed coalitions. Our results find however no evidence that ‘wearing a blue helmet’ increases the probability of a terrorist attack at home.     

一种内陆环境溢油综合监测系统方案设计

针对内陆环境油品储存和运输场所面积大、植被多、地形多变、单一技术难以实现全范围溢油监测的情况,将复杂内陆环境下的油品储运区分为作业区、周围山地和水域3个主体区域,设计了一种基于无线通信的溢油综合监测系统方案。系统由综合监测报警中心和可燃气体、土壤溢油、水面浮油3个探测报警模块通过无线连接组成,各模块均包括若干相应的探测器和现场报警控制器,可对油品作业区及周围山地、水域进行全范围实时监测,及时报警泄漏溢油隐患,降低泄漏溢油事故发生几率。
