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.     

RAISING THE COST OF REBELLION: THE ROLE OF THIRD‐PARTY INTERVENTION IN INTRASTATE CONFLICT

This paper presents a simple model to characterize explicitly the role that an intervening third party plays in raising the cost of rebellion in an intrastate conflict. Extending the Gershenson‐Grossman (2000 Gershenson, D. and Grossman, H.I. 2000. Civil conflict: ended or never ending?. Journal of Conflict Resolution, 44(6): 807–821.  [Google Scholar]) framework of conflict in a two‐stage game to the case involving outside intervention in a three‐stage game as in Chang et al. (2007b Chang, Y.‐M., Potter, J. and Sanders, S. 2007b. War and peace: third‐party intervention in conflict. European Journal of Political Economy, 23(4): 954–974.  [Google Scholar]), we examine the conditions under which an outside party optimally intervenes such that (i) the strength of the rebel group is diminished or (ii) the rebellion is deterred altogether. We also find conditions in which a third party optimally intervenes but at a level insufficient to deter rebellion. Such behavior, which improves the incumbent government’s potential to succeed in conflict, is overlooked in some conflict studies evaluating the effectiveness of intervention. One policy implication of the model is that an increase in the strength of inter‐governmental trade partnerships increases the likelihood that third‐party intervention deters rebellion.     

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.     

Determining a role for a military ombudsman in the South African National Defence Force

In recent years, South Africa has come to be used by international terrorists as a safe house, for paramilitary training purposes, as a base from which to plan attacks on other countries and as a conduit for financial transactions. South Africa's own counter-terrorism initiatives have been labelled ‘reactive’ by analysts. Indeed, the existing counter-terrorism regime suffers from a lack of political will to issues of corruption and ineptitude bedevilling the security apparatus of the state. However, using lessons learned from other countries, Pretoria can yet turn the tide against international terrorism by adopting more pro-active measures and by undertaking steps aimed at the depoliticisation and decriminalisation of the security forces.     

The Race that wasn't

ABSTRACT

Graham Farmelo's new book on the early British nuclear weapon program assembles a fascinating cast of characters in a gripping narrative. It particularly succeeds at illustrating the importance of “atomic energy” imagery in the United Kingdom well before the discovery of fission, and provides nuanced insights into Churchill's handling of issues relating to the atomic bomb and scientific expertise. However, in arguing that the British had a “lead” on the manufacture of atomic bombs that was “lost” to the United States during the early Manhattan Project, the book overstates its case, and in the process misunderstands what it took to make the bomb.     

高校评建过程中“三个符合度”的理性思考

"三个符合度"是一个学校办学水平高低的最集中体现,也是高校教学评估的实质和精髓.在迎评促建的过程中,高校的自评自建工作应该围绕以提高"三个符合度"为中心来展开.     

有限扩域上的Fuzzy子域

在文[3]中,引入了更一般的Fuzzy理想等概念,使Fuzzy代数结构的研究进一步深入进行。本文作为Fuzzy结构理论中的又一课题,引入了Fuzzy子域等概念,对有限扩域上的Fuzzy子域的构造问题进行了比较详细的讨论,得到了几个类似于[2]中的表示定理。尔后,引入了诱导Fuzzy子域,对单纯代数扩域上的诱导Fuzzy子域进行了研究。
