基于能力的远程航空通信用频需求获取策略

提出一种基于能力的远程航空通信用频需求获取策略。分析了远程航空通信用频需求获取的基本思路。在此基础上,将远程航空通信用频需求自顶而下划分为任务需求、能力需求、效果需求3个层级,通过对层级进行定义和关系分析,给出基于能力的远程航空通信用频需求获取框架,最后对需求获取准则进行定义,得出一套较为科学有效的远程航空通信用频需求获取流程。     

“What is dear to you?” Survey of beliefs regarding protection of critical infrastructure against terrorism

Up to the present, there is only very little research on how the population perceives terrorism and its threats, even though support from the population is crucial for effective counterterrorism. By eliciting beliefs and subjecting them to content analyses, six factors were found that determine the protection worthiness of a target in the people's view: the potential damage to “people,” “symbolism,” “economy,” “politics,” “nature,” and “image/publicity.” These empirically found factors are in line with factors specified by terrorist target selection models. They differ in the strength of their cognitive representation among participants and, thus, their subjective importance to the people. The first three factors are shared among all participants, whereas the latter ones could only be found in a part of the participant sample. People's judgments of the targets' protection worthiness differ substantially from their judgments of the targets' attractiveness to terrorists, even though the same factors seem to be involved. This study offers an insight into the people's mental model about protection worthiness of targets. Together with classical risk analysis and knowledge about terrorists, these results can form a basis for setting up a holistic scheme for critical infrastructure protection.     

谈英语教学中学生创造思维的培养

目前，我国外语教学普遍存在费时较多、收效较低的现象，特别是精读课教学，向来只注重给学生注入语言知识，而轻视学生创造思维能力的培养。要解决这一问题，外语教学工作者必须改变教学观念，避免在外语课教学中只重识记而轻思维这一现象。     

基于能力的指挥信息系统需求获取方法

一体化联合作战是信息化条件下的新的作战形式,为满足一体化联合作战的需要,作战能力与联合作战概念的结合已成为大势所趋.目前国内常用的指挥信息系统需求获取方法缺乏顶层作战概念和目标的指导,没有考虑联合作战的要求.通过分析,将指挥信息系统需求划分为作战需求、用户需求和系统需求3个层次,总结了指挥信息系统在一体化联合作战的要求下应当具备的能力,参考美军JCIDS系统方法和流程,提出了基于能力的指挥信息系统需求获取方法.
