This book constitutes the refereed proceedings of the 20th Australian Joint Conference on Artificial Intelligence, AI 2007, held in Gold Coast, Australia, in December 2007.

The 58 revised full papers and 40 revised short papers presented together with the extended abstracts of 3 invited speeches were carefully reviewed and selected from 194 submissions. The papers are organized in topical sections on machine learning, neural networks, evolutionary computing, constraint satisfaction, satisfiability, automated reasoning, knowledge discovery, robotics, social intelligence, ontologies and semantic Web, natural language systems, knowledge representation, expert systems, applications of AI, and short papers.

This book tells the story of the Christian religious movement led by Dona Beatriz Kimpa Vita in the Kingdom of Kongo from 1704 until her death, by burning at the stake, in 1706. Beatriz, a young woman, claimed to be possessed by St Anthony, argued that Jesus was a Kongolese, and criticized Italian Capuchin missionaries in her country for not supporting black saints. The movement was largely a peace movement, with a following among the common people, attempting to stop the devastating cycle of civil wars between contenders for the Kongolese throne. Thornton supplies background information on the Kingdom, the development of Catholicism in Kongo since 1491, the nature and role of local warfare in the Atlantic slave trade, and contemporary everyday life, as well as sketching the lives of some local personalities.

This book explores Africa's involvement in the Atlantic world from the fifteenth through the eighteenth centuries. It focuses especially on the causes and consequences of the slave trade, in Africa, in Europe, and in the New World. Prior to 1680, Africa's economic and military strength enabled African elites to determine how trade with Europe developed. Thornton examines the dynamics that made slaves so necessary to European colonizers. He explains why African slaves were placed in significant roles. Estate structure and demography affected the capacity of slaves to form a self-sustaining society and behave as cultural actors. This second edition contains a new chapter on eighteenth century developments.
