From control to parasitism

This article sets out to investigate the current paradoxical roles of border control agencies in order to contribute to the theoretical debate on border porosity and related security issues in West Africa. The colonial demarcation of African borders accounts for their porous nature initially, as borderland populations challenged the unjust scission of their cultural, economic, geographical and geopolitical spaces. However, new forms of porosity also evolved over time, masterminded by new actors. Drawing on the Ghana–Togo border case, and through interviews, observation and documentary analysis, this article argues that border control agencies are partly responsible for the current border porosity and attendant security problems as their jurisdiction has shifted to a multi-layered border parasitism. The article is not, however, an attack on border law enforcement agencies; rather it attempts to explore their roles in shielding the region, already exposed to terrorism and piracy, from further security threats.     

UNITED STATES—SOUTH AFRICA RELATION

Abstract

The article evaluates the security challenges that are likely to occur along international borders in East Africa with the advent of the East African Community Common Market in July 2010. In an attempt to illustrate the porosity of borders and the likelihood that criminals could take advantage of the situation, the author describes the ease with which transnational crime could thrive (in the absence of efficient border security measures) under the guise of informal cross-border trade that derives its basis largely from the customs and historical linkages in the region. Border towns in the region are considered zones of risk but also opportunities for quick money-making ventures and deals that tend to attract a variety of criminals. While the danger is not alarmingly high, there is a likelihood that with the opening up of the East African Community to the free movement of goods and people, criminals will exploit this freedom to commit crimes such as human trafficking, drug smuggling and moving terrorists and contraband goods unless mechanisms are put in place to curtail these activities. Should this not happen, the mission of the East African Community could be jeopardised.     

力导向模型的复杂网络社区挖掘算法

在复杂网络中发现和刻画社区结构是近年来复杂网络研究的重点方向之一。提出了一种社区挖掘的新思路,即根据力导向模型的原理,通过计算社区与节点之间的作用力来决定节点的社区归属。根据该思路设计了基于力导向模型的算法框架FDCD(Force-directed Community Detect),并利用FR模型、KK模型、LL模型和Q模型进行了验证。实验表明,基于FDCD算法框架的多种不同算法不仅能较好地识别社区结构,而且基于LL模型的FDCD算法达到了线性计算复杂度,能适用于大规模网络的社区挖掘。     

AD HOC TRIBUNALS IN AFRICA

International judicial norms developed slowly during the Cold War but have recently begun to draw on the experiences of the Criminal Tribunal in the former Yugoslavia and Rwanda. These ad hoc bodies had to respond quickly to emergency situations by combining different international approaches to justice and prosecution. The Special Court for Sierra Leone is the latest of these experiments. Despite having had more time for reflective discussion and negotiation, the Special Court faces the same challenge and constraint: the parameters of time and resources are set by political imperatives. The International Criminal Court goes some way to addressing the problems of funding, good judicial appointments and contrasting legal systems, the details of future trials will not be easy. Ad hoc tribunals will probably still have a role to play in cases where the ICC cannot intervene.     

The International Conference on the Great Lakes Region

In April 2012 a number of former rebels who had been integrated into the Forces Armées de la République Démocratique du Congo (FARDC) mutinied and formed the Movement of March 23, better know as the M23 rebel group. The International Conference on the Great Lakes Region (ICGLR) has been mediating between Kinshasa and the M23 rebel group since 2012, without much success. In August 2013, the Southern African Development Community (SADC) issued a communiqué after its 33rd Summit of Heads of State and Government, stating that while it commends the ICGLR efforts, the talks have become protracted and a deadline needs to be set. The summit also called for an urgent joint ICGLR–SADC summit to address the crisis in the eastern Democratic Republic of Congo (DRC). In addition to this development, the chair of the ICGLR is to be rotated in December 2013, when President José Eduardo Dos Santos of Angola replaces President Yoweri Museveni of Uganda. To date, the mediation has been headed by Uganda and this has raised concerns over the credibility of the ICGLR-led process, since Uganda has been accused of supporting the M23 rebellion in a report released in November 2012 by the United Nations Group of Experts on the DRC. One could question whether the Angolan leadership will bring anything new that could have an impact on the crisis. Many expect that the perceived neutrality that Dos Santos could bring to the negotiations may be a positive step towards reviving the talks that have all but stalled at this point. Another issue of interest is whether the joint ICGLR–SADC summit could instil new life into the mediation process.
