Military Spending,Conflict and External Debt in Sub-Saharan Africa

The damaging economic effects of the debt crises on Africa in the late 1980s encouraged considerable research on the determinants of external debt in developing economies. Although sub-Saharan Africa's (SSA) debt was cut by two-thirds by 2008, through two debt relief programmes, debt in the region has since been rising at an increasingly rapid pace. This study provides an empirical analysis of the determinants of external debt in SSA over the period 1960–2016, using dynamic panel methods. It also considers two potentially important factors that have received relatively little attention. One is military spending, rarely considered, despite a number of well-publicised scandals over the procurement of unnecessary and expensive high-tech weapons systems. A second, is the possibility that the countries studied have been involved in conflict. The empirical results point to a positive impact of military spending on external debt, but with some evidence of heterogeneity across the countries. Furthermore, findings indicate that the positive effect of military expenditure on debt becomes more marked in countries that have been affected by conflict. These results imply that policies to improve security and reduce military spending could be beneficial in reducing external debt and, potentially, improving economic performance in the region.

基于组合赋权法的联合作战协同效能评估指标

针对联合作战协同效能评估指标体系不够科学和权重计算方法比较单一的问题,立足联合作战协同的本质特性和作战协同效能评估尺度,通过维度映射构建了包括整体性、精确性、时效性、灵活性和稳定性等5个一级指标、作战行动有序性、力量优势互补程度等10个二级指标的联合作战协同效能评估指标体系。通过构建离差最小组合赋权模型给出了主客观赋权合成的方法,并结合指标体系权重计算验证了方法可行性。     

Terrorist choice: a stochastic dominance and prospect theory analysis

The paper explores terrorist choice by applying two well-known theoretical frameworks: stochastic dominance and prospect theory (PT). We analyse each pair of attack methods that can be formed from the RAND-MIPT database and the Global Terrorism Database. Instances of stochastic dominance are identified. PT orderings are computed. Attention is accorded to the identification of ‘trigger points’ and the circumstances that may lead to an increased likelihood that a terrorist will select an attack method associated with a higher expected number of fatalities, i.e. a potentially more damaging attack method.     

核心力量训练在手榴弹立姿投掷中的应用

核心力量训练作为现代体能训练的重要内容,近年来引起了国内许多体育界研究者的高度重视,已取得了一定的研究成果。但是,在部队的手榴弹立姿投掷训练课目中尚未引入这一训练理念。本文通过阐述与核心力量训练相关的概念、手榴弹立姿投掷核心力量训练的作用,总结出适用于部队实际、开展手榴弹立姿投掷核心力量训练的方法和原则。     

建构、人本教学模式在《体育保健学》课程中应用研究

目的研究建构、人本教学模式在体育保健学授课过程中对学生学习兴趣和教学效果的影响。方法以建构、人本教学相结合的理论模式为研究对象,以传统教学模式为对照,通过测试获得学生平均成绩进行统计学分析,并以问卷调查方式获取实验班学生兴趣水平构成比的变化资料。结果传统教学模式授课后,2组学生首测成绩无显著性差异(S1=81.5±3.92分,S2=79.23±2.78分,P=0.071);对实验班采用建构、人本教学模式授课后,2组学生的平均成绩有显著性差异((T1=82.96±3.62分,T2=71.39±4.21分,P=0.001);并且,实验班学习兴趣的构成比有显著提高,兴趣高的比例由39.73%提高至56.76%。结论建构、人本教学模式理论能提高体育保健学的教学效果和激发学生的学习兴趣。     

关于繁荣中国“社会美”的断想

社会美的具体形象的力量与导向是多种因素的综合反映,要把社会美放到具体的田野工作中去考察,把富于创新理念的美育理论置于具体的背景中去理解,这样有利于深入发掘蕴含于群众之中的社会美资源。要在悬置经验本位和相关理论假设的前提下得出个案研究的新结论。在美育领域,无论是教育者还是受教育者都是审美主体,因为两者的目的都是为了更好地对待审美对象,实现主体与客体的互通共融。社会美的无限的丰富性内容有待于我国美学美育工作者去发现,重要的是要从具体的鲜活的事例出发。
