The vast expansion of transportation systems on land, sea and in the air throughout the twentieth century has allowed for the development of economic, social and political connections across the globe undreamed of by our ancestors. However, this expansion has brought with it familiar problems such as airport delays and gridlock in our major cities. Fortunately, parallel progress in system science and information technology can provide us with the appropriate tools for rational and efficient solutions to our exponentially increasing transportation demands. This encyclopedia addresses the analysis, modelling and control of today's and tomorrow's traffic and transportation systems in a concise, comprehensive single volume. Well over 100 articles have been specially commissioned, or revised from the acclaimed Systems & Control Encyclopedia, to provide an overview of and first reference to models, control methods and practical aspects of all forms of traffic and transportation systems with a particular emphasis on efficient utilization of available infrastructure, plus a consideration of their historical, organizational, economic and social impacts. The Concise Encyclopedia of Traffic & Transportation Systems will be essential for professional and academic scientists and engineers in any discipline concerned with the movement of people and materials.

Rumination (recyclic negative thinking), is now recognised asimportant in the development, maintenance and relapse of recurrenceof depression. For instance, rumination has been found to elevate,perpetuate and exacerbate depressed mood, predict future episodesof depression, and delay recovery during cognitive therapy. Cognitive therapy is one of the most effective treatments fordepression. However, depressive relapse and recurrence followingcognitive therapy continue to be a significant problem. Anunderstanding of the psychological processes which contribute torelapse and recurrence may guide the development of more effectiveinterventions. This is a major contribution to the study and treatment ofdepression which reviews a large body of research on rumination andcognitive processes, in depression and related disorders, with afocus on the implications of this knowledge for treatment andclinical management of these disorders. * First book on rumination in depressive and emotional disorders* Contributors are the leaders in the field* First editor is a rising researcher and clinician with specialistinterest in depression, and second editor is world renowned for hiswork on cognitive therapy of emotional disorders
