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.     

联合国维和警察防暴队甄选考试改革对维和培训的影响及对策

2012年9月颁布的《联合国维和警察防暴队行动能力评估标准作业程序》对联合国防暴队甄选及行动能力评估的组织、实施程序、考查标准等方面都进行了较大的调整。从联合国维和警察防暴队甄选标准作业程序的改革入手,以考试为突破口和着眼点,研究程序的改革对维和警察防暴队培训的影响,制定应对策略,以时维和培训工作具有指导作用和借鉴意义。     

语文课程文本缺席现状及回归策略

在富有灵性的语文新课程中,阅读不能远离文本,远离作者,只有忠实于文本这一阅读中的特殊主体,以文本和作者的具体状况为基础的创造性阅读和个性化体验,才是语文新课程下真正的阅读。本文聚焦新课程小学语文阅读教学实践领域,分析随意肢解、拓展、歪曲、冲淡语文教材载体的文本缺席现状,从对文本价值的理解、文本处理规律的把握、教师引导阅读的作用和教师课程功力的提升四个角度,提出回归策略。     

改革开放以来我国经济法取得的主要成效及发展方向

中国特色经济法是改革开放的产物,有力地促进了社会主义市场经济的健康、快速发展。经济法在保证经济实现科学发展的同时,自身也突破了对调整能力的传统认识,区分了经济法与行政法,明确了经济法的正确定位,创新了经济法的发展观,提出了“经济法主体”概念,冲破了公法与私法的界限,形成了与相关学科协调发展的经济法学研究格局。今后,经济法的发展必须重视从完善社会主义市场经济基本制度,健全现代市场体系,规范政府科学干预经济生活,宏观调控的重点、热点、难点问题和基础理论研究的创新上把握研究重点,保证经济实现科学发展。

Study on performance degradation and failure analysis of machine gun barrel

An increase in the use of the gun barrel will cause wear of the inner wall, which reduces the muzzle velocity and the spin rate of the projectile. The off-bore flight attitude and trajectory of the projectile also change, affecting the shooting power and the accuracy. Exterior ballistic data of a high-speed spinning projectile are required to study the performance change. Therefore, based on the barrel's accelerated life test, the whole process of projectile shooting is reproduced using numerical simulation technology, and key information on the ballistic performance change at each shooting stage are acquired. Studies have shown that in the later stages of barrel shooting, the accuracy of shooting has not decreased significantly. However, it is found that the angle of attack of the projectile increases as the wear of the barrel increases. The maximum angle of attack reaches 0.106 rad when the number of shots reaches 4300. Meanwhile, elliptical bullet hole has appeared on the target at this shooting stage. Through combining external ballistic theory with simulation results, the primary reason of this phenomenon is found to be a significant decrease in the muzzle spin rate of the projectile. At the end of the barrel life, the projectile muzzle spin rate is 57.5% lower than that of a barrel without wear.
