网络化弹药协同作战效能研究

首先分析了网络化弹药协同作战的过程,提出了网络化弹药作战效能的评估方法及定义,并对影响作战效能的因素进行了分析。针对作战方案在实战或仿真推演过程中反映战场态势等方面的特征,相应地提出了网络化弹药作战的效能指标:目标识别率、目标杀伤率、假目标攻击率、效费比,然后利用作战仿真法,验证了不同影响因素下协同作战和非协同作战的效能。仿真结果表明了网络化弹药协同作战具有较高的作战效能。     

Mandated defence offsets: can they ever deliver?

Defence offsets are elements of defence procurement deals additional to the primary content. Offsets are usually expected to yield technological or industrial benefits to the purchasing country (e.g. countertrade, technology transfers, or additional jobs) and military buyers often require suppliers to make offsets available “cost-free.” The authors argued previously that such strategies achieve little of value to buyers that lack market power and are unnecessary otherwise, since purchasers with the market power to extract more value for money from foreign suppliers can do so anyway. This article also focuses on the supply side of offset deals. The USA is the world's largest defence offsets supplier but the US government opposes offsets demands as economically inefficient and trade distorting. Even if offsets are inefficient and trade distorting, they may still benefit a materiel-exporting country such as the USA as they may induce exports and create associated benefits for the offsets provider.     

边境地区群体性事件预警指标体系构建研究

科学、可行的指标体系是群体性事件预警的核心。在坚持完备性与最小性原则、科学性与可行性原则、敏感性与动态性原则、全局性与针对性原则的前提下,利用层次分析法、专家调查法,构建了以边境地区经济、社会保障、公共安全维护、民族与宗教、边民心理状况以及周边环境六大因素为支撑的边境地区群体性事件预警指标内容,并形成了6个一级指标,12个二级指标,44个三级指标的边境地区群体性事件预警指标体系。     

基于神经网络的柴油机技术状态主元信息提取方法

在柴油机技术状态监测时,表征其技术状态的特征参数有很多,合理提取状态主元信息是一项关键的任务。分析研究了人工神经网络的信息提取原理和方法。以某型坦克柴油机为例,通过柴油机性能检测试验测取了能够反映柴油机技术状态变化的典型特征,建立了O ja神经网络信息提取模型,提取了柴油机技术状态的主元信息。分析结果表明:提取的主元信息能够反映柴油机技术状态随柴油机使用时间的变化趋势。该方法为坦克柴油机的技术状态监测与故障诊断提供了有效手段。     

Reforming the bras tendus? The Congolese National Police reforms, 2003–2016

The security sector reform (SSR) programme in the Democratic Republic of the Congo (DRC) has failed, according to a former high-level member of the United Nations (UN) mission in the DRC, as a large section of the country remains outside government control, and the security institutions of the state continue to constitute one of the predominant sources of insecurity for the local population in a number of ways. Based on several field studies, this article critically scrutinises the SSR of the Congolese National Police (Police nationale congolaise; PNC) and the efforts to reform it between 2004 and 2016. It further attempts to explain why so little progress was made in the SSR of the PNC, despite extensive involvement from donors. The article shows that the instrumental and traditional approach to SSR is partly to blame, because in this case it failed to address the root problems and initiate the needed fundamental reform and reconstruction of the police force. It also shows that reforming local security institutions becomes even more difficult when the local authorities do not support the effort.
