One size does not fit all: personalized incentives in military compensation

A critical element in implementing a compensation scheme including nonmonetary incentives (NMIs) is recognizing that preferences vary widely across Service members. There are at least three sources of variability: across different population classes, across individuals within a population class, and across NMI packages for a particular individual. Surveys across different military communities, ranks, and years of Service show the difficulty of identifying any NMI that has significant value for even 50% of the active duty force. At the same time, approximately 80% of the surveyed Service members expressed a significant positive value for at least one NMI. Therefore, one-size-fits-all incentive packages will not be nearly as effective as more personalized incentive packages. The authors discuss variability in Service member NMI preferences and outline an approach to implementing personalized NMI packages in military compensation through a sealed-bid reverse auction, where Service members select individual NMIs from a “cafeteria-style” menu of options.

Economic Competition and Nuclear Cooperation

The number of bilateral nuclear cooperation agreements surged during the “nuclear renaissance” of the past decade. This proliferation is only partially explained by the prevailing approaches that focus on strategic imperatives. To supplement these explanations, this study draws on neoliberal models of economic competition to posit that bilateral agreement negotiations also exhibit conditions of “uncoordinated interdependence” and maneuvering to gain market share. Case evidence suggests the contours of supplier state bids for civilian assistance are determined at least as much by considerations about economic competition as they are by positive strategic goals. In addition, this study identifies several cases of cooperation where there appears to be little or no strategic motive for export agreements. The study concludes that patterns of economic competition and the influence of peers in defined competitive spaces alter material payoffs and impact policies. It also identifies a surprising role for principled restraint in dampening strategic and economic competition in some dyads.     

基于营区精、气、神文化表达的自然仿生设计

精、气、神文化是营区规划设计的核心.自然仿生设计为营区精、气、神文化的表达提供了独特而有效的方式.通过对营区精、气、神文化的解读,发掘出自然仿生的3个层面,即“形”之仿生,“意”之仿生和“结构”之仿生.在营区规划设计中,当自然仿生的这3个层面得到有效表达,实现有机统一,营区就会产生独特的文化气质与魅力,从而体现其精、气、神特色,展现部队的“军营魂”.     

Analysis on the resistive force in penetration of a rigid projectile

According to the dimensionless formulae of DOP (depth of penetration) of a rigid projectile into different targets, the resistive force which a target exerts on the projectile during the penetration of rigid projectile is theoretically analyzed. In particular, the threshold V_c of impact velocity applicable for the assumption of constant resistive force is formulated through impulse analysis. The various values of V_c corresponding to different pairs of projectile-target are calculated, and the consistency of the relative test data and numerical results is observed.     

装甲兵模拟训练系统体系架构

近年来,装甲兵模拟系统建设和模拟化训练有了长足的发展,但仍然存在缺乏顶层规划、标准不一、资源不共享、模块不重用、体系不完整等诸多问题。基于体系工程建设理念,探索了装甲兵模拟训练系统体系架构,主要考虑了顶层设计,重点放在了系统的组成结构、相互关系,从总体上把握体系的整体功能、需要解决的问题,采取的技术路线。实践表明,体系架构独立于系统的具体实现技术,保证了各组成部分可以通过重用、重组等方式来适应不同阶段、不同目标和领域的装甲兵模拟训练需求,提高了系统的利用效率,降低了模拟训练系统的开发成本。
