AID,GLENEAGLES AND THE RUN-UP TO THE MILLENNIUM +5 SUMMIT

Africa has emerged as a strategic location for transcontinental narcotics trade. Particularly the West African subcontinent has turned into a cocaine warehousing and trans-shipment hub along the way to the European underground markets. At this juncture, African drug networks (ADNs) began to play a momentous role in global drug trade, and pose a considerable threat to international security, as they operate in more than 80 countries. The United Nations Office on Drugs and Crime, Interpol, and Europol perceive ADNs as one of the primary issues in international counter-narcotics policy. These agencies have launched several multilateral initiatives to contain the West African threat. None of these initiatives, however, retarded the expansion of the problem. Indeed, the containment efforts turned out to be quite embryonic. The ADNs eventually entered the Turkish market by the early 2000s. West African drug networks (WADNs) in particular have begun to operate within Turkey extensively, often supplying and distributing drugs. The gravity of the threat became ever more serious by 2012. The upsurge of the new threat has compelled the Turkish drug-law enforcement agencies to adopt new policies and counter-strategies. These policies have to be based upon proper strategic analysis of the threat. This paper seeks to address the need for a threat assessment of ADNs. It investigates the dimensions of the problem, profiles the members of WADNs, their modes of operation, and the factors that compelled them to exploit the illicit Turkish drug markets. The analyses are based upon the scrutiny of 227 narcotic interdictions files and statements from the African individuals in these case files. The paper concludes by presenting policy implications and recommendations for the Turkish security and foreign-policy institutions to cope with this impending threat.

An n-step, 2-variable search algorithm for the component placement problem

The component placement problem is a specialization of the quadratic assignment problem that has been extensively studied for a decade and which is of considerable practical value. Recently, interest in component placement algorithms has risen primarily as a result of increased activity in the field of computer-aided design automation. This paper deals with the methodology of component placement and is based on the results of considerable operational experience. A tutorial presentation of tree search placement algorithms is provided, and an improved placement procedure is described which is demonstrated to be effective in generating near optimal solutions to the component placement problem. These solutions are completely reproducible and are obtained at an acceptable expenditure of computational resources. An additional objective is an assessment of performance of the class of near optimal algorithms. In particular, the question- how close to optimal are the near optimal solutions- is examined.
