The Amritsar Massacre and the minimum force debate

This article re-examines one of the most infamous incidents in British imperial history: the Amritsar Massacre of 1919, and analyses it within the context of the British Army's minimum force philosophy. The massacre has long been regarded as the most catastrophic failure of minimum force in the history of the British Army. This article reconsiders the arguments over the shooting at Amritsar and the role of Brigadier-General Reginald Dyer, and questions the accepted view that the massacre was such a failure of minimum force. It argues that the circumstances surrounding the massacre must be understood before judging the incident and given these factors it is possible to see it within a minimum force framework.     

基于时频单源点检测和聚类验证技术的欠定混合盲辨识算法

针对欠定混合盲辨识问题,提出了一种基于时频单源点检测及聚类验证的盲辨识算法。检测各个源信号的时频单源点,利用奇异值分解的方法求解不同单源点集合对应的混合矢量,利用基于k均值的聚类验证技术完成源信号数目和混合矩阵的联合估计。算法放宽了已有方法对时频单源区域的假设,不需要假设信号存在时频单源区域,可以完成仅存在离散的时频单源点条件下的欠定混合盲辨识;同时克服了传统算法需要假设源信号个数已知的不足,可以有效地估计源信号数目。仿真结果验证了算法的有效性。     

把握党的群众路线科学内涵需厘清的几个逻辑问题

当前,以“为民、务实、清廉”为主要内容的党的群众路线教育实践活动在全党全军深入开展,准确把握党的群众路线科学内涵,必须厘清党员干部要“相信谁”、“依靠谁”、“为了谁”和“我是谁”这四个逻辑问题,才能科学地指导教育实践活动深入开展,这既是确保活动取得良好成效的客观要求,也是新形势下丰富马克思主义党建学说的应有之义.     

探析党对军队领导的绝对性——深刻理解十八大精神，铸牢立军之本和建军之魂

习近平主席在中央军委扩大会议上强调：党对军队绝对领导是我军的立军之本和强军之魂。这是对十八大报告关于“党对军队的绝对领导”论述的进一步深化。认真学习十八大精神,必须切实弄清党对军队领导绝对性的本质特征、科学本源和集中体现,毫不动摇地坚持党对军队的绝对领导。     

加强社会主义核心价值体系建设的理性思考

社会主义核心价值体系是兴国之魂,是社会主义先进文化的精髓,决定着中国特色社会主义发展方向。建设社会主义核心价值体系,必须以马克思主义为指导思想,确立中国特色社会主义共同理想,在实践中坚持价值体系的辩证性,从而巩固全党全国各族人民团结奋斗的思想道德基础。     

新课改背景下西部地区小学《科学》课程学与教的现状初探——以新疆石河子市为例

通过问卷调查结合访谈和观察,对石河子市小学科学课程学与教的现状进行调查,结果发现:学生对科学课具有浓厚的兴趣,且非常喜欢现行的教材,但因本区小学科学教师师资不足、专业素养不高,加之教学设备有限,教学资源匮乏,多数学校班级规模过大,导致实践环节得不到保障,影响了课程教学质量。据此,强化小学科学教师队伍建设,加大科学教育经费的投入力度,缩减班级规模,改善学习环境,是本区适应新课改提高科学课程教学质量的有效途径。     

Missile systems: “Flexible modularity” and incremental technological change in military production∗

It is often stated that technological change in the military field is characterised by the introduction of radical innovations rather than by incremental processes of technological change. This article illustrates the diversity of military innovation by arguing that technological change in missiles systems is dominated by incremental change. While some large weapons platforms display the design rigidities normally associated with complex systems, missiles are characterised by “flexible modularity”. Flexible modularity facilitates the continuous introduction of upgrades, and makes missile systems amenable to gradual technological change. Besides, it has significant implications for the future role of missile systems, and poses special problems for missile disarmament and technology control initiatives.     

Country survey VIII: Federal republic of Yugoslavia

This survey article focuses on defence economics issues and provides data and analysis on the Federal Republic of Yugoslavia's (FRY) defence policy, defence spending, the size of its armed forces, its defence industries and the cost of the civil war. The main section is devoted to the period from 1990 to the present and deals with the following aspects: the situation after the break‐up of the former Yugoslavia, general economic data; the cost of the civil war, the defence budget; the armed forces; the manufacture of armaments and the structure of the defence industry.     

An Empirical Analysis of the Arms Race Between South and North Korea

This study analyses an arms race between South and North Korea over the period 1963–2000. Despite the strategic importance of the Korean Peninsula, the arms race between South and North Korea has rarely been studied. In this study, the South–North arms race is empirically estimated using Richardson’s action–reaction model. The pattern of South–North arms race between the Cold War (1963–1989) and the post‐Cold War eras (1990–2000) as well as the existence of an arms race is examined comparing both countries’ defence spending, number of military personnel and tactical aircraft.     

Market reactions to regulations on minerals from the democratic republic of the Congo

Using an event study approach to analyze stock market data from the United States, I investigate how regulations on conflict minerals sourced in the Democratic Republic of the Congo were perceived by investors. I find that for a subset of mining companies, stock returns were abnormally high when regulations in the US became more likely. I also find that returns were higher for communications equipment manufacturing companies when strong regulations in the DRC were announced. I argue that these responses were due to the competitive environments faced by each of these company types. These findings relate to debates surrounding the effects of the conflict mineral regulations. While some critics argue that reporting requirements were tantamount to a ban on minerals from the DRC, I find that stock returns for a subset of companies were sensitive to legislation in the DRC after legislation became law in the US, suggesting that market participants did not expect a complete trade ban on regulated mining and trading activities.
