First published in 1990, this volume considers the question: is there any hope for economic recovery in Africa? Written by a team of leading development economists, the book takes a close look at the economic decline of Sub-Saharan Africa and provides a set of guidelines for promoting economic recovery. Stressing the need for greater co-operation between African states, the contributors outline the economic and social policies required to put this crisis-torn region back on the road to sustained development.

Service Life Prediction of Polymers and Plastics Exposed to Outdoor Weathering discusses plastics and polymers and their unique applications, from sealants used in construction, to polymer composites used in planes. While these materials are important enablers for advanced technologies, exposure to weather changes the very properties of plastics that make them so useful. This book reviews current research needs and provides a consensus roadmap of the scientific barriers to validated predictive models for the response of polymers and plastics to outdoor exposure.
