群体决策与个人决策的选择

决策对于管理者来说至关重要,因为它关系到人们能否顺利实现目标.何时采用群体决策或个人决策,取决于三个方面的问题:群体决策和个人决策的效率,群体决策和个人决策的冒险倾向,以及小团体意识.     

机群超视距作战联合战术信息系统的效能分析

建立了机群联合战术信息系统在超视距作战中综合机群的传感器、导航和火力控制系统,组织对目标协同探测、辨识和火力控制的系统模型,以及它的效能评估模型.仿真计算表明此信息系统能有效增加机群超视距作战的效能,但噪声和欺骗干扰会显著地影响它的效率.     

基于椭圆曲线群上的零知识证明

通过研究椭圆曲线群,给出基于其上的2个零知识证明方案,这2个方案均使得甲方向乙方宣称自己拥有某种信息,并通过互动证明使其确信具有该信息,但同时还未泄漏该信息。

基于散射机理分类与方位对称性判决的极化SAR人造目标提取

由于极化SAR人造目标电磁散射的复杂性,已有极化SAR人造目标提取方法难以完整地提取出感兴趣区域内不同类型的目标.针对这一不足,提出一种基于散射机理分类与方位对称性判决的提取新方法,充分利用目标与杂波在散射机理类型及方位对称性上的差异进行提取.与已有方法相比,该方法对极化SAR图像中不同极化特征的人造目标都有较好的提取性能,提取结果更为完整和准确.利用全极化SAR实测数据验证了本方法的有效性和优良性能.     

Why they fight? Reconsidering the role of motivation in combat environments

The current combat motivation model based on primary group thesis assumes that the main force behind motivation is peer-bonding or otherwise known as unit cohesion. Cohesion is perceived as an all-encompassing factor that leads to satisfactory (or unsatisfactory in lack thereof) military effectiveness and performance in conflict environments. However, the article identifies three main problems with this perspective: 1. mono-dimensional view of motivation; 2. motivation based on heteronomy, and 3. self-reporting bias. The current model does not consider motivation as a separate entity from cohesion; it does not place motivation as fundamental human value; lastly, it takes motivation as granted by-product of socialization. The article proposes a new combat motivation model based on The Self-Determination Theory. The theory maintains that human motivation requires satisfaction of three psychological needs of competence, relatedness, and autonomy. The degree of satisfaction of those three needs leads to different types of regulated motivations – a continuum from intrinsic to extrinsic – each of which has specifiable consequences for learning, performance, and well-being of an individual.
