Comprehensive Prohibition of Nuclear Weapons: An Emerging International Norm?

ABSTRACT

There have been calls for the abolition of nuclear weapons from the day they were invented. Over the last fifteen years, some indications can be found that such calls have been getting louder, among them Barack Obama's famous 2009 speech in Prague. In this article, we investigate if support for a comprehensive norm that would prohibit development, possession, and use of nuclear weapons is really growing. To assess the current status of that norm, we use the model of a “norm life cycle,” developed by Martha Finnemore and Kathryn Sikkink. We then analyze 6,545 diplomatic statements from the review process of the Treaty on the Non-Proliferation of Nuclear Weapons as well as from the UN General Assembly First Committee on Disarmament and International Security, covering the years 2000 to 2013. The evidence shows that a comprehensive prohibition can be considered an emerging international norm that finds growing support among states without nuclear weapons and nuclear weapon states alike. Only a core group of states invoke the norm consistently, however. This leads us to conclude that the “tipping point” of the life cycle, at which adherence to a new norm starts to spread rapidly, has yet to be reached.     

Book review

This paper investigates the economic roots of separatist terrorism in Turkey. The political conventional wisdom is that poverty in highly Kurdish‐populated, south‐eastern Turkey is one of the most important causes of separatist terrorism and Turkish–Kurdish conflict in Turkey. Therefore, many economic policies have been implemented to improve the economic conditions in the south‐eastern part of the country. Using the Global Terrorism Database and Vector Autoregression (VAR) methodology, I find that there is no causal relationship between economic conditions in south‐eastern Turkey and separatist terrorism. Therefore policy‐makers should be cautious in using economic measures to prevent separatist terrorism in Turkey.     

U.S. Troops and Foreign Economic Growth

By way of an evolutionary game model we show that mediation in international conflicts might be harmful to the conflicting parties. In fact, under anarchy both parties can be better off than under an international regime if mediation reduces the parties’ reactive capacities (i.e. their abilites to respond to an aggression). This result is applied to issues currently discussed in the literature on international relations such as the role of the United Nations as a mediator of international conflicts.     

SOCIAL PREFERENCES FOR NATIONAL DEFENCE AND POLICE ENFORCEMENT IN WESTERN EUROPE

We study the determinants of social preferences for national defence and for police and law enforcement. For this task, we estimate a bivariate ordered probit model for a set of European countries (France, Finland, Norway, Portugal, Spain and Sweden) in 2006. Determinants of spending decisions for defence and police are found to be linked but are of significantly different magnitudes. Besides, measures against terrorist threats are positively linked to police and defence spending increases, while the subjective perception of fiscal pressure has no influence. Finally, no significant differences are found between Northern and Southern Europe.     

Waiting time analysis of the M/G/1 queue with finite retrial group

We consider an M/G/1 retrial queue with finite capacity of the retrial group. First, we obtain equations governing the dynamic of the waiting time. Then, we focus on the numerical inversion of the density function and the computation of moments. These results are used to approximate the waiting time of the M/G/1 queue with infinite retrial group for which direct analysis seems intractable. © 2007 Wiley Periodicals, Inc.
