The African Peace and Security Architecture and its partners

This article presents survey data on the African Peace and Security Architecture (APSA). It focuses explicitly on two aspects: the internal constitution and achievements of the APSA; and coordination and cooperation with external actors, such as Regional Economic Communities, the United Nations and the European Union. The survey, conducted between October 2011 and December 2012, targeted 198 security experts in international organisations, think tanks, academia and non-governmental organisations. It reveals the APSA's current stage of development, achievements and challenges.     

Rentier peacekeeping in neo-patrimonial systems: The examples of Burundi and Kenya

International peacekeeping in Africa has developed dynamically in the last decade. The majority of global missions are deployed to the continent, the largest regional contingent of troops comes from Africa, and the African Peace and Security Architecture has made significant progress. Peacekeeping is Africanized today more than at any time before. However, mainstream research has insufficiently paid attention to African agency in this context. This article sheds light on the often neglected influence of African politics on international peacekeeping missions. The focus is set on the consequences of neo-patrimonial political systems, which can use international peacekeeping missions as an opportunity to generate rents. It will be shown that such a rent-seeking approach is highly problematic for the troop-contributing as well as mission-hosting countries. Instead of curbing conflict, rentier peacekeeping is prolonging and exporting it. The empirical examples used are the Burundian and Kenyan involvement in peacekeeping in Somalia.     

Determining crane areas for balancing workload among interfering and noninterfering cranes

This article treats the problem of subdividing an area for storing containers such that the workload is evenly shared among the cranes operating the resulting subareas. We consider two crane sets: while noncrossing constraints between cranes of the same set need to be observed, cranes of different sets do not interfere. Such a problem setting is, for instance, relevant for scheduling the (un‐)loading of vessels by parallel quay cranes operating on opposing berths or in container yards with cross‐over cranes. We formalize the resulting optimization problem, prove computational complexity, and present exact and heuristic solution procedures. © 2012 Wiley Periodicals, Inc. Naval Research Logistics, 2012
