MILITARY EXPENDITURE AND ECONOMIC GROWTH IN DEVELOPING COUNTRIES: EVIDENCE FROM SYSTEM GMM ESTIMATES

The effect of military expenditure on economic growth in developing countries has been investigated by many empirical literatures. However, there is little consensus of that effect and the diversity seems to come from the use of different models and different estimators. This article applies the Augmented Solow Growth Model to examine the influence of military expenditure on economic growth for 35 developing countries over the period of 1975–2009. By using the system Generalized Method of Moments (GMM) estimators, empirical results indicate that defence has a negative and significant effect on economic growth in the sample countries.

‘What Kind of War is This?’

This article explores the nature of the American war in Vietnam in an effort to determine whether it was a response to an indigenous uprising or an external effort by the Communist Party of Vietnam (CPV) to use a wide array of policies and programs to unite North Vietnam and South Vietnam under the party’s leadership. It argues that, although there initially were elements of the South Vietnamese population that rose against the southern leadership, the CPV gained control of their resistance and relegated it to a secondary role in the CPV war effort.     

Baixa do Cassang: Ending the abuse of Portuguese Africans

On 4 January 1961 in Baixa do Cassange, in the north of Angola, the blacks who worked in the cotton fields began a strike. The army with air support was called to quell the rebellion, and the article emphasizes the importance of air support tethered to the ground forces, particularly in a remote and vast area of operations in the tropical rainy season. In this case, the support originally came in the form a squadron of Lockheed PV-2 Harpoons from Luanda, some 300 kilometers away. These open-ocean reconnaissance aircraft and their crews were ill-suited for the task. When this became apparent, four small Auster D5/160s were relocated from Negage to Malange, among the ground forces. The Austers flew reconnaissance missions over the troubled zones, dropped provisions and messages to the advancing ground forces, and served as a backup communications link. When the strike ceased after three weeks, the Austers assumed a humanitarian role in support of the starving population. The conclusion is that air support to ground forces is indispensable, must be properly tailored to the job, and must operate as an integral part of the ground forces.     

军事指挥类期刊对军事学术研究的透视

军事指挥类期刊主要依靠各级军事指挥员,服务于部队全面建设。在军事学术研究队伍不断发展壮大的今天,军事指挥类期刊为部队“能打仗、打胜仗”军事理论研究服务,但军事学术研究存在着研究群体优势和合成作战理论优势发挥不够的问题。因而,要高度重视军事学术研究人才培养,加大经费投入,强化军兵种之间合成作战理论研究的力度。

强脉冲 CO2 激光与靶的相互作用

在真空背景下的实验表明,当微秒量级的强脉冲激光与靶材相互作用时,由于靶材的升华,激光维持爆震波依然存在。爆震波产生的压缩波传入靶内,该应力波的作用是材料破坏的重要因素。而强脉冲激光引起的汽化反冲压力、热应力和烧蚀破坏也是不可忽视的因素。实验还表明,在真空背景下维持爆震波足以将后续激光屏蔽。     

论毛泽东对中国共产党思想领导规律的揭示

《论语》的“知”论探微

《论语》中的“知”是一种知识、才智、智慧,也是一种认知方式。它的内容广泛,可粗分为“闻见之知”和“德性之知”,“知”来源于“生而知之”和“学而知之”。孔子主张通过多见、多闻、多习、多行等方式“学而知之”。“知”是为了获取一种“智”的生命智慧,为了培养一种“仁智”双修的理想人格。
