‘Innovate or die’: Organizational culture and the origins of maneuver warfare in the United States Marine Corps

The purpose of this article is twofold. First, this article contributes to the understanding of the origins of maneuver warfare as the capstone doctrine of the Marine Corps. It does so by identifying a second source that fostered change in the Marine Corps – one in addition to disquiet about the conduct of the war in Vietnam – which stemmed from the challenges posed by the United States' post-Vietnam strategic and military reorientation. And second, this article examines the influence of organizational culture, or identity, on innovation in the Marine Corps. A critical strand in the growing literature on military innovation focuses on organizational culture and how it influences the behavior and responses of particular military organizations. This article contributes to this literature by analyzing the influence of the organizational culture of the Marine Corps in shaping what was deemed an appropriate response to the challenges it confronted in the 1970s.     

Escalation and de-escalation of violence in insurgencies: Insights from Northeast India

Insurgencies in the Northeast of India have been a recurring phenomenon since India's independence in 1947. One of the most significant aspects of the multiple insurgencies has been the use of violence for political goals. By drawing upon three cases of insurgencies in Northeast India, the article offers a conceptual framework on escalation and de-escalation of violence in insurgencies. The article argues that the most critical variables which have a direct bearing on the levels of insurgent violence are: popular support, loss of legitimacy and the state's counter-response.     

A lost work of El Lobo: Lieutenant-Colonel Charles T.R. Bohannan's unpublished study of guerrilla warfare and counterinsurgency in the Philippines, 1899–1955

Charles Ted Rutledge Bohannan (1914–1982) became an integral agent of US counterinsurgency operations during the early Cold War, contributing to both the success of the COIN effort to defeat the communist Huk insurgents in the Philippines and the stalled COIN efforts in Vietnam. In the early 1960s, he wrote a short and compact analysis of the US and Filipino experience of guerrilla warfare, from the Philippine–American war until the defeat of the Huk Rebellion. It was never published. Reprinted here, Bohannan's analysis of lessons learned makes a substantial contribution to the history of American ideas of unconventional warfare by an expert who contributed these lessons to the successful defeat of an insurgency in South East Asia.     

基于拉盖尔模型的超声信号渡越时间测量性能分析

传统窄带模型仅能通过数值计算统计出超声信号渡越时间的测量性能。针对这一问题,提出基于拉盖尔模型计算理论克拉下限的方法。研究了拉盖尔函数及其时间导数的性质,得到时间导数内积矩阵,并将其应用到费舍尔矩阵中,能够快速精确计算克拉下限。对混合指数模型仿真表明,在高斯白噪声背景下,渡越时间方差与理论克拉下限具有良好的一致性;受窄带噪声和反射等因素影响,实测数据的渡越时间方差与理论克拉下限存在较大偏差。
