试论我国当代消防文化建设的三个切入点

针对消防文化的内涵,探讨我国当代消防文化建设的三个切入点：即在消防工作中体现军人核心价值观、消防工作中的战斗精神与革命英雄主义气概、消防工作中的探索精神和创新意识;指出围绕这三个切入点进行消防文化建设的具体原则和措施.     

火箭弹卷弧尾翼的轻量化研究

针对火箭弹卷弧尾翼在特定气动载荷下的轻量化问题,基于结构动力学理论,依托ABAQUS非线性有限元软件,建立了火箭弹卷弧尾翼的有限元模型。通过对比碳纤维复合材料(CFRP)和合金钢材料的卷弧尾翼的有限元分析,得出了碳纤维复合材料在满足强度和刚度的要求下,使卷弧尾翼减重达80%。该方法为火箭弹卷弧尾翼的轻量化设计提供了一种参考和借鉴。     

Performance measurement in military operations: information versus incentives

We explore the impact of strategic assessment efforts on military organizations at war. To do so, we construct a model to explore the impact of a principal’s choice among imperfect performance metrics for a military operation. In doing so, the principal must consider both the incentivizing and informational properties of the metric. We show the conditions under which uncertainty regarding the nature of the agent, as well as uncertainty regarding the operational environment, drives a metric choice that induces pathological behavior from the agent. More specifically, a poor metric choice can create an overly optimistic assessment and end up prolonging the conflict. We illustrate the model’s insights in the cases of World War II and the Vietnam War.     

SECURITY GOVERNANCE IN SOUTH AFRICA

In the ten years since the establishment of South Africa's first inclusive democratic government, an ambitious, extensive and systematic process of reform has been carried out in the governance of security. The process is widely regarded as having been successful and a model for other processes of ‘security sector reform’ in the context of transitions from authoritarian forms of governance to democratic ones.

That this been achieved with hardly a shot fired in anger is a remarkable achievement and a credit to visionary political leadership as well as organisational capacity, in other words to effective security governance.

At the same time, progress has been uneven and sometimes fragmentary, policy intentions and commitments have not always been translated into practice, the end results have not been to everyone's liking, and transformation has engendered its own pathologies. Thus several challenges remain in improving security governance.

This article provides a broad overview of the roles played by the various actors in the governance of the security sector, including the executive, parliament and civil society. It examines the main policy frameworks and touches on organisational transformation, because it is impossible to deal with governance in isolation from these issues. Policy processes and the frameworks they give rise to—in particular—are critical for effective governance. This article deals with the defence, safety and security and intelligence fields. A comprehensive overview would need to include the governance of criminal justice and foreign policy. The article does not seek to make an overall evaluation of governance, but to identify achievements, shortfalls and challenges.     

基于云理论一二元语义的雷达装备保障指挥效能评估模型

针对云重心和云模型评判方法存在的信息丢失、难于评判以及信息扭曲等问题,从确定权重等级、评价集和评价结果3个方面对模型进行了改进和完善．应用二元语义确定指标权重,避免了评价信息的丢失和扭曲,采用综合云的思想确定评价集,充分利用评价者给出的信息,简化相似云的理论来定量衡量评价结果,从而建立了基于云理论一二元语义的雷达装备保障指挥效能评估模型．
