Colonial violence and its ‘Small Wars’: fighting the Kuki ‘guerillas’ during the Great War in Northeast India, 1917–1919

ABSTRACT

This paper concerns the lesser known British counterinsurgency (COIN) operations in Northeast frontier of India during the First World War. Officially known as the ‘Kuki Operations’, it was considered as part of the Great War. Carried out in isolation from press and public, and shelved in colonial archives, the event remained invisible until today. Yet, it registers a critical case of colonial COIN doctrine where the ‘moral effect’ doctrine was employed without being questioned. It unleashed enormous amount of organized violence, ranging from shoot at sight to indiscriminate burning of villages, wholesale destruction of property and livestock, prevention of cultivation and rebuilding of villages, forced mass displacement in jungles or in ‘concentration camps’, and collective punishment (communal penal labour and payment of compensation) after the war. This paper argues that the theory of ‘minimum force’ and the practicability of the ‘moral effect’ doctrine as applied by the Empire, sit oddly with each other at the frontier, where violence was seen both as a natural and moral orders. Violence as an ‘imperatively necessary’ method to bring order in a disorderly frontier, in the opinion of colonial state, informs and registers Northeast India as geography of violence.     

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.     

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.

反电动势对无扰载荷航天器精确定向的影响

无扰载荷航天器中非接触式作动器反电动势会引起有效载荷模块与支持模块之间的耦合，影响有效载荷模块的精确定向性能。通过建立无扰载荷航天器的耦合动力学模型，分析非接触式作动器反电动势对有效载荷模块精确定向性能的影响。考虑六支杆立方构型无扰载荷接口，结合拉格朗日方程和牛顿欧拉方法建立有效载荷模块平台动力学模型。推导非接触式作动器的输出力模型，并引入有效载荷模块平台动力学模型，给出考虑非接触式作动器反电动势的耦合动力学模型。将支持模块上飞轮动静不平衡引起的谐振作为干扰力矩，建立了无扰载荷航天器在轨定向状态的Simulink仿真模型。仿真结果表明，反电动势系数越大，干扰力矩对有效载荷模块的影响越大，有效载荷模块精确定向精度越低。
