经济视野的新时期军事安全战略

经济全球化深刻影响和改变了世界经济、政治、军事安全形势,促使我们探索新时期的国家军事安全战略。本文试图由经济视角透视新时期军事安全战略,简要分析了经济全球化背景下我国军事安全面临的挑战,强调经济安全是新时期军事安全战略的立足点和重要战略目标,并探讨了经济软实力作为非战争军事斗争方式的运用及经济全球化影响下的新时期军事安全战略的特征。     

新课程理念下数学探究教学的理论与实践探索

数学探究教学作为新课程标准倡导的一种教学模式,它注重学生的参与体验,强调在教师的指导和点拨下展开具有探究性和一定创造性的教学活动。探究教学是发展学生个体,培养学生能力,提高学生素质的重要途径。另外,有关探究教学案例的开发也是不容忽视的一个重要方面。     

声尾流自导鱼雷导引策略仿真与优化

在分析尾流几何模型及其气泡分布密度的规律的基础上,首先建立了较贴近实际的尾流声学仿真模型。其次,按照尾流自导检测流程,基于反射系数推导了尾流层及海面气泡层的回声级模型,由此建立了鱼雷声学自导检测模型。随后,根据研究需要设计了基于鱼雷作战使用评估理论的声尾流自导鱼雷仿真系统,该系统能够真实模拟尾流自导系统工作过程及鱼雷水下运动过程。最后,以该仿真系统为依托,实现了声尾流自导鱼雷应对空穴或断层的修正导引策略的仿真优化。应用结果表明:该研究对于尾流自导鱼雷导引策略优化和尾流自导仿真方法研究具有实际应用价值。

Vicarious warfare: The counterproductive consequences of modern American military practice

This article examines contemporary modes of American warfare. It posits the concept of “vicarious warfare” as a means of capturing prominent patterns in warfighting approaches. Although rooted in long-standing traditions of military practice, vicarious warfare is sufficiently novel as to be identifiable as a distinct phenomenon. The precise manifestation or combination of vicarious methods vary according to the specific circumstances and political contexts prevailing in different theaters. However, America’s general preference is to fight its wars by delegating tasks to proxies and limiting exposure of its own military to danger. Where U.S. forces are employed directly, this takes place largely in the shadows. Such approaches have clear attractions, offer undoubted tactical advantages, and permit successive administrations to maintain a persistent tempo of operations that evades rigorous democratic scrutiny. Yet, prominent cases and numerous studies suggest that vicarious warfare has a high potential to generate counterproductive effects and significant strategic harm.     

Think again – supplying war: reappraising military logistics and its centrality to strategy and war

This article argues that logistics constrains strategic opportunity while itself being heavily circumscribed by strategic and operational planning. With the academic literature all but ignoring the centrality of logistics to strategy and war, this article argues for a reappraisal of the critical role of military logistics, and posits that the study and conduct of war and strategy are incomplete at best or false at worst when they ignore this crucial component of the art of war. The article conceptualises the logistics–strategy nexus in a novel way, explores its contemporary manifestation in an age of uncertainty, and applies it to a detailed case study of UK operations in Iraq and Afghanistan since 2001.     

MAD,not Marx: Khrushchev and the nuclear revolution

The revival of nuclear strategy in US policy and scholarship has been strengthened by arguments that the ‘nuclear revolution’ – the assumption that thermonuclear bombs and missiles had made major war too dangerous to wage – does not affect international behaviour as much as nuclear revolution advocates claim. This article shows that the Soviet leader Nikita Khrushchev indeed regarded nuclear war as too dangerous to wage, a decision which manifested itself not so much in foreign policy or military doctrine but in his determination to avoid war when the possibility arose. We argue that Khrushchev’s experience provides us with a more useful way to characterise the nuclear revolution and suggest some implications of this argument for contemporary debates about nuclear weaponry.     

Classical geopolitics,realism and the balance of power theory

Since the end of World War II, classical geopolitics as a particular form of realism has been disengaged from the development of mainstream realist theories. This disengagement has not only concealed the value of classical geopolitics as a framework of analysis for policy and strategy, but also created an increasing rift between theory and policy in contemporary realist theories. This paper seeks to reengage classical geopolitics with mainstream realist theories by clarifying its realist traits and analytical characteristics, (re)stating its core propositions and probing into its potential contribution to the development of mainstream realist theories. This paper contends that classical geopolitics, while having a distinctive pedigree, can arguably be considered an integral part of the family of realist theories in view of its basic theoretical assumptions concerning international anarchy, the unit of analysis and power politics. As a framework of analysis, classical geopolitics incorporates three interrelated strategic propositions. Those three propositions not only constitute the theoretical core of classical geopolitics, but also manifest a peculiar balance-of-power conception that is essentially distinct from those proposed by mainstream realist theories. This paper argues that those three propositions combined promise to fill in prominent lacuna in the balance-of-power research programme, and also have significant implications for contemporary world politics.
