新疆初中生学校生活满意度调查研究

本研究采用自编调查问卷对409名新疆S市初中生进行学校生活满意度调查,结果表明：（1）初中生的学校生活满意度总体状况较高,但自我满意度和学习环境满意度较低;（2）年级、成绩、学校或班级活动参与程度和家庭经济状况是影响初中生学校生活满意度的主要人口统计学变量,其中初一年级学生的教学满意度和学习环境满意度高于其他两个年级的初中生,成绩优秀的学生的同学关系满意度、自我满意度和家庭满意度明显高于成绩中等和较差的学生,经常参加活动的学生的同学关系满意度、自我满意度和学习环境满意度高于偶尔和从来不参加活动的学生。最后,研究提出提高初中生学校生活满意度的相关对策。     

军用柴油机高压共轨系统共轨管设计与仿真

结合大功率柴油机配机要求,进行了高压共轨喷油系统共轨管结构设计研究。针对某型军用柴油机结构和共轨管结构特点,提出适合的柴油机高压共轨系统方案,确定了双轨结构型式的共轨管,计算了不同共轨管的结构参数。通过建立双共轨管的简化仿真模型,分析双轨结构不同参数的共轨管压力波动变化,提出了双共轨管参数方案,结果表明该方法能获得较合理的双共轨管参数。     

Deterrence under nuclear asymmetry: THAAD and the prospects for missile defense on the Korean peninsula

The 2016 decision to deploy Terminal High Altitude Area Defense (THAAD) to South Korea has generated multitude of intensely politicized issues and has proved highly controversial. This has made it challenging to alleviate, let alone clarify, points of analytical and policy tensions. We instead disaggregate and revisit two fundamental questions. One is whether THAAD could really defend South Korea from North Korean missiles. We challenge the conventional “qualified optimism” by giving analytical primacy to three countermeasures available to defeat THAAD–use of decoys, tumbling and spiral motion, and outnumbering. These countermeasures are relatively inexpensive to create but exceedingly difficult to offset. Second, we assess the optimal way to ensure South Korean national security against North Korean missiles. By examining the balance of capability and issues of credibility/commitment, we show that the U.S. extended deterrence by punishment remains plentiful and sufficiently credible even without enhancing the current defense capability.

Military Expenditure as a Proxy for State Power. The Case of France

This paper attempts to build a simple indicator of state power. Military expenditure is the paper’s point of departure, with the definitions given by NATO, SIPRI and others. This definition is discussed and a power version is build, using French budgetary data. Then a defence of the result against traditional or non-traditional critics is presented under an imperative of action. Finally, this concept is enlarged and a new concept of power expenditures is given, one more time using French budgetary data. The conclusion is that this large expenditure concept is an unbiased but imperfect indicator of the will to act, and has to be completed by GDP to indicate the capability to act in the long-run.

炮兵火力任务分配的优化模型

现代作战,参战兵种多,炮兵的火力单位和类型更为复杂,不同的火力单位具有不同的毁伤效果,如何用最小的代价取得最大的军事效益,是一种火力任务分配的优化问题.根据不同炮种和目标的特点,建立在一定约束条件下的炮兵火力任务分配模型,并将其转化为指派问题,运用匈牙利算法求解,达到优化分配火力任务的目的.通过仿真计算证明这是辅助指挥员进行射击决策的一种有效手段,为作战指挥理论提供了一种新的数学模型.     

The EU Global Strategy and diplomacy

The new EU Global Strategy has significant implications for EU diplomacy, in terms of both goals and means. This article first analyses the timing of the strategy as an exercise in diplomacy in its own right. Second, it argues that the strategy outlines a more expansive and noticeably more smart power-oriented approach to diplomacy in practical terms. Finally, it notes that the strategy has a new meta-narrative for EU diplomacy, which seeks to project a blend of both realistic assessment and idealistic aspiration.
