First published in 1997, this volume contributes to the knowledge for the trade of vegetables, fruits and tubers (so-called horticultural commodities). As African policy makers try to keep pace with new developments in private food trade, they require knowledge of the structures of private trade systems and the factors that govern their long-term development. The study analyses the structure and development of horticultural marketing channels in Kenya. It is based primarily on surveys of some 500 farmers in four districts and 750 horticultural traders in 18 market places. Commercial horticultural farmers, domestic traders, export traders, agents, facilitators, marketing cooperatives and processors are all reviewed. The study devotes special attention to the efficiency of collecting wholesalers, and to the development of rural assembly markets. It develops a model which can elucidate vertical differentiation processes in the Kenyan horticultural channels. The analyses show that marketing channel theory can be of great relevance to the developing world. The proposed vertical differentiation model can aid in predicting future changes in horticultural marketing systems, in Kenya as well as in other African countries.

Is Artificial Intelligence really an apocalyptic threat to society? Could A.I. actually take control of humanity? As agents Cassiopia Cassell and Scott Markman close in on a modern day Jack the Ripper, the world around them suddenly begins to change. Machines are behaving oddly. Traffic lights seem almost malicious. Super computers are refusing to accept input. Cassiopia's high IQ has always been a reliable source of creative solutions during difficult situations. Combined with Markman's martial arts talents the pair always seemed unstoppable. But now they are faced with an invisible enemy, an enemy with a thousand eyes. Is artificial intelligence really a danger to humankind? Has your home computer been behaving properly lately?
