一种基于MTS的网络区域管理工作站实现策略

网络扩容的一个重要障碍是异构子网连接后的互连管理问题。分区域的一体化管理无疑是一种解决办法。本文提出一种基于管理协议细栈(MTS)来构造一体化的区域管理中心(RMC)的策略,这里的 RMC 可实现彼此间的管理通信和互操作,从而也解决了扩容后的互连管理问题。结合正在进行的工程实践,文章还进一步从技术角度上讨论了实现策略。

Winston Churchill and the third front 1

The premise of most Western thinking on counterinsurgency is that success depends on establishing a perception of legitimacy among local populations. The path to legitimacy is often seen as the improvement of governance in the form of effective and efficient administration of government and public services. However, good governance is not the only basis for claims to legitimacy, especially in environments where ethnic or religious identities are politically salient. Some experience in Iraq suggests that in environments where such identities are contested, claims to legitimacy may rest primarily on the identity of who governs, rather than on how whoever governs, governs. This article outlines the intellectual foundations of existing policy and doctrine on counterinsurgency, and argues that development and analysis of counterinsurgency strategy would benefit from a greater focus on the role of ethnic and religious identity in irregular warfare.

Controlled warfare: how directed-energy weapons will enable the US Military to fight effectively in an urban environment while minimizing collateral damage

US military operations are increasingly conducted within urban environments and with these operations come the risk of increasing the number of civilian casualties and infrastructure damage. The use of non-lethal weaponry, such as directed-energy weapons, is one method for minimizing collateral damage. This method enables US military forces to effectively fight within urban environments through force escalation capabilities. Using a series of historical examples and future scenarios for urban warfare, this article highlights deficiencies affecting military capabilities in military urban operations, addresses the consequences of collateral damage, assesses the effectiveness of directed-energy weapons in military urban operations and encourages further funding, research and integration of non-lethal weaponry, such as directed-energy weapons, within the US military.     

Winning hearts and minds: legitimacy in the Namibian war for independence

Efforts at winning hearts and minds (WHAM) impact on and are affected by perceptions of legitimacy. In the Namibian war for independence (1966–1989) efforts of the South African counterinsurgent forces at winning hearts and minds focused mainly on persuading the population to cooperate in exchange for material benefits and services. The article demonstrates that this successfully contributed to a dimension of legitimacy that is conceptualized as pragmatic legitimacy. However, other dimensions of legitimacy are identified in which the South Africans were lacking, that is in moral, legal, and identity-based legitimacy. Furthermore, in areas where control was contested and where the population could not be shielded from insurgent intimidation, it is argued that the effects of coercion outweighed legitimacy altogether.     

How the High North became Central in NATO Strategy: Revelations from the NATO Archives

From the late 1970s and until the end of the Cold War, the ‘High North’ constituted a central theatre for military forces. Extensive NATO preparations were made, a solid infrastructure developed in northern Norway, and frequent and large-scale exercises were carried out. These developments, from the late 1970s, were much discussed by scholars and strategists. However, the change of perception, laying the foundation for the military build-up, had actually occurred a decade earlier, in the late 1960s. This change has not yet been given its rightful attention, partly because the relevant documents have only recently become available. This essay takes the chronology of events back into the 1960s and to NATO's secret discussions between the national Ministers of Defence and Chiefs of Staff. The most significant turning-points were the Flexible Response strategy of 1967; SACLANT's concern over increased Soviet naval activity and his ‘Maritime Strategy’ studies of 1965 and 1967; NATO's awakening to the Soviet SSBN threat in 1967; and the concept of ‘External Reinforcement of the Flanks’ of 1968 – finally followed by the ‘Brosio Study’ (named after the then NATO Secretary-General) of 1969. As a consequence of these developments NATO's ‘tactical northern flank’ was set to become an independent strategic theatre.     

一种新的星载高分辨宽测绘带SAR运动目标

本文针对星载多通道高分辨宽测绘带合成孔径雷达系统,提出了一种地面运动目标检测和参数估计方法,该方法首先利用空时自适应处理进行杂波抑制,然后采用传统SAR成像处理得到模糊的运动目标图像,接着利用恒虚警检测技术检测出所有运动目标,包括真实目标和由于多普勒模糊引起的虚假目标,再根据模糊图像的空间位置关系从所有成像目标中检测出运动目标的真实成像位置,最后根据运动目标的斜距历程得到因运动目标速度引起的图像位置偏移,由此估计得到运动目标速度。该方法具有运算量小、检测精度高等优点,星载仿真数据验证了本文方法有效性。     

Military Spending and Economic Growth in the Middle East Countries: Bootstrap Panel Causality Test

This study revisits the causal relationship between military spending and economic growth in 10 Middle East countries via a panel causality analysis that accounts for cross-sectional dependence and heterogeneity across countries. Our results indicate unidirectional causality from military spending to growth for Turkey; one-way causality from economic growth to military spending for Egypt, Kuwait, Lebanon, and Syria; bidirectional causality for Israel; and no causality in either direction for Jordan, Oman, and Saudi Arabia. The empirical evidence does not provide consistent results regarding the causal relationship between defense expenditure and economic growth in these countries.
