美军"作战云"理论的制胜机理是以云计算技术作为物质基础和技术依托,以"云部署、云聚合、云攻击(防御)、云消散"体现作战过程,以"集中指挥、分布式控制和分散执行"为基本指控方式,以"跨域协同"作为作战协同的基本方式。由于该理论实现了战场信息的有效融合和共享,作战力量的动态聚能和释能,作战任务的临时赋予和即时完成以及不同领域作战能力的互补增效,因此将促使美军的武器装备、力量结构、作战方式及战场形态等发生新的重大变化。  相似文献

教师聘用制改革是高校人事制度改革的重点和核心,是在遵循双方地位平等的原则上,以合同方式明确规定双方的权利、义务和责任的一种任用方式。教师聘用制的实施使高校与教师之间的雇佣关系本质发生了转变。本文从心理契约、职业生涯等方面对此进行分析,并指出在新雇佣关系下的成功要素。  相似文献

语言作为人类的交际工具,总是为一定的交际目的在不同的交际场合使用。人们运用语言这一工具进行社会交际总是受到现实环境的支配与影响。任何语言的使用都有语境,语篇作为言语交际中传递信息的载体,同样也离不开语境。语境体现为语篇的语言选择,而语篇的语言选择又建构了语境。语境是交际双方共同的认知前提。对于语境的研究和分析,有助于更加准确地研究和分析基于这个语境产生的语篇。  相似文献

Why did some Arab militaries remain loyal to authoritarian rulers amid mass uprisings during the Arab Spring while others defected to the opposition? One popular explanation shows this variation with reference to the degree of military institutionalization: institutionalized militaries defected, while patrimonial militaries remained loyal. This article argues that the institutionalization hypothesis does not provide a complete account of the mechanisms through which the degree of military institutionalization leads to either defection or continued loyalty. This shortcoming stems from the fact that scholars have treated military institutionalization as a catch-all concept for three distinct variables: ethnic stacking of the military, patronage distribution, and organizational factionalization. Examining the interaction between these variables highlights the mechanisms through which military defection occurs, and therefore that disaggregating institutionalization into its component parts provides a more complete explanation of military behavior during the Arab Spring.  相似文献

美军航母战斗群空袭火力对地攻击效能分析   总被引:2,自引:1,他引:1  
以美军航母战斗大队标准编成为例,简要分析了美军航母战斗群的空袭火力构成.进而分别建立了机载普通对地攻击弹药和巡航导弹、空地导弹对地面目标的毁伤能力的模型.然后以此为基础,从空袭兵器的突防概率、对目标的发现概率、对各类目标的毁伤概率和空袭某一目标所需的兵力四个方面,对航母战斗群空袭火力体系的对地攻击效能进行了深入研究,并建立相应的数学模型.最后根据在历次战争中得到的经验数据,对美军航母战斗群空袭火力对地攻击效能进行了计算,并分析了计算结果,为科学判断敌情提供了依据.  相似文献

Vietnam was a complex conflict, which historians and political scientists have struggled to understand. Some of the bitterest disputes in the historiography revolve around the US approach to counterinsurgency in Vietnam. Many different facets of the war have received the attention of filmmakers, and an examination of their work suggests new ways of thinking about the conflict. This article considers film portrayals of three phases of the Vietnam War – firstly, the early period of ‘political action’, then the advisory period, and finally the Americanization of the war after 1965. It suggests that by examining the experiences of participants in each of these phases, Vietnam War cinema helps to illustrate the problems that faced various American approaches to counterinsurgency in the conflict. Combined with the importance of films in determining popular perceptions of both historical conflicts and counterinsurgency in general, it suggests that they are worthy subjects of study and critique.  相似文献

This article analyses the steps taken by the Russian government, with the aid of a powerful local clan, the so-called Kadyrovtsy, to subdue the Chechen insurgency. It highlights the strategy used by Russia, under whose patronage former anti-Russian guerrilla fighters were transformed into paramilitary allies of the Russian government; later these former insurgents were incorporated into the regular Russian army and other state security forces. The article also identifies problems that are connected with the activities of the Kadyrovtsy in Chechnya and Russia, and the spillover into the diaspora; it also contextualises the issues faced by the contemporary Chechen ruling clan and the geopolitics of the Caucasus within the research framework of paramilitarism and counterinsurgency.  相似文献

The US strategy in Afghanistan has fallen short of neutralizing the insurgency that threatens the future stability. The primary insurgency's leadership council, the Quetta Shura, has effectively managed influence through a shadow government and superior tactics in recruiting marginalized tribal leaders, leading to a questionable outcome once Coalition forces withdraw in 2014. This article summarizes the threat posed by the Quetta Shura, coinciding with the deficiencies in the current US policy, and recommends a more viable strategy conducive to the current circumstances, based on historical and cultural precedence. Coalition forces have put a great amount of time, money, and effort into establishing a more stable Afghanistan. The USA needs a more aggressive strategy to counter the aspirations of the insurgency, thereby giving the Afghans the opportunity to further progress in the future. Under the current circumstances and policies, a peaceful transition after the Coalition withdrawal is becoming more unlikely.  相似文献
