ECONOMIC SANCTIONS AND CULTURE

We address empirically the question of why international economic sanctions are, or are not, chosen as instruments of foreign policy and the question of what determines their success. We hypothesize that cultural linkages between nations are an important factor in explaining both instrument choice and conflict outcomes. Countries that share significant cultural attributes are found to be less likely to apply economic sanctions against one another than countries lacking such cultural ties. However, it is precisely in the case of culturally similar sender and target nations that sanctions are most likely to succeed.     

ARMS CONTROL CONTINUUMS

In July 2001, member states will gather in New York for the UN Conference on the Illicit Trade in Arms in All its Aspects. It represents part of the effort to establish controls on small arms and light weapons. This article argues that it is possible that nuclear and conventional arms control represent two ends of a continuum, with common goals and a common set of mechanisms and processes at work. A decade after the end of the Cold War, it is not surprising that the international community is working on mechanisms to deal with conventional arms. The existence of a continuum and connections between conventional and nuclear arms control is less evident. The two arms control communities appear to function in isolation of each other. The return to the debate on small arms and light weapons echoes post-World War I and II periods. The fact that small arms control is back on the agenda within the context of the UN may signify recognition that any kind of arms control serves the same purpose—preventing and mitigating the effects and duration of, and bringing an end to conflict.     

Using public health information to inform,build support and implement policies for gun violence prevention: A case study from the gun ban referendum

Gun violence is one of the most serious health problems in Brazil. Information on gun deaths and injuries is collected by the Ministry of Health. This data has been used very successfully to inform and design public policies for preventing gun violence. This article analyses the use of public health information by researchers and activists, as well as government officials and the media, to reveal the severity of firearm injuries and deaths and to gain consensus on the need for reforms to national gun laws. It also assesses the resounding ‘no’ vote in a recent disarmament referendum to decide whether to prohibit the sale of guns and ammunition. The results of the Brazilian referendum are a lesson to other countries struggling to deal with high levels of gun violence, showing that it may not always be enough to have data to back up efforts to change policies—as people's decisions around gun ownership and use, as well as their choices regarding security policies, are motivated by a complex interaction of factors.
