Mantle convection is the fundamental agent driving many of the geological features observed at the Earth's surface, including plate tectonics and plume volcanism. Yet many Earth scientists have an incomplete understanding of the process. This book describes the physics and fluid dynamics of mantle convection, explaining what it is, how it works, and how to quantify it in simple terms. It assumes no specialist background: mechanisms are explained simply and the required basic physics is fully reviewed and explained with minimal mathematics. The distinctive forms that convection takes in the Earth's mantle are described within the context of tectonic plates and mantle plumes, and implications are explored for geochemistry and tectonic evolution. Common misconceptions and controversies are addressed - providing a straightforward but rigorous explanation of this key process for students and researchers across a variety of geoscience disciplines.

This close synchronic analysis of Exodus 1-2 looks at how the pericope's structure, language, focalization and management of information form its conception and judgement of its events and characters. A coherence of concerns is detectable in Exodus 1-2 with allusions to Genesis and the later chapters of Exodus. One chapter is assigned to each of seven narrative unities and deals in various ways with its narrative problems. The resulting eclectic choice of analytical tools includes the study of Proppian structural functions, repetition, public rhetoric, narrative speeds, order and symbolism.

In December 2005 I changed my mind [1]. Up until that time I had put my name on one case history in 400 publications [2]. I changed my mind and realized that reading case histories could be a good learning exercise. I had previously considered useful case histories to be essentially live case demonstrations. Indeed, I had persuaded years of endocrine clinical fellows that writing case histories was not something to be encouraged. But the cheese moved. Livecase historypresentationsbecametoo complexforeasy digestibility. Themany investigations and vast literature review required more contemplation than a live presentation had required in the past. And writing these exercises as a formal case history allowed the complex literature to be better understood. Furthermore, as our evidencebase hasgrown,theidiosyncraticapproachso commoninlivecase dem- strations of the past has become totally unacceptable. The written or prepared case has become the ideal forum for demonstrating how to manage a medical case to the greatest bene?t of the patient. Indeed, written case histories are clearly the very best means of showing medical care guidelines in real practiceandofrevealingtheiradvantagesanddisadvantages[3]. Thatdoesnotmean we should no longer give live case demonstrations. Demonstrating a supportive and knowledgeable patient can be a magni?cent teaching tool. For many years I have presentedendocrinologycasesto our?rst-yearmedicalstudents,andformanyyears these physicians later told me how much they enjoyed them and that they remember them well. So clearly, both formats of delivery remain effective.

Plate tectonics can drift continents and push up mountains, but what drives the plates? This is an insider’s account of how we answered questions posed over two centuries ago, and completed geology’s quest for a driving mechanism. Forging through confusing evidence, apparent contradictions and raging debates we arrived at not one but two mechanisms: sinking plates and rising plumes.

Small group research is of particularly wide interest to people working in a fairly broad variety of areas concerned with understanding conflict, especially for practitioners and researchers concerned with conflict resolution, peace, and related areas. The editors will focus on six main topical areas of small group research, which include: - Cooperation, competition, and conflict resolution - Coalitions, bargaining, and games - Group dynamics and social cognition - The group and organization - Team performance - Intergroup relations

Dynamic Earth presents the principles of convection in the earth's mantle in an accessible style. Mantle convection is the process underlying plate tectonics, volcanic hotspots and, hence, most geological processes. The book summarises key observations and presents the relevant physics starting from basic principles. The main concepts and arguments are presented with minimal mathematics, although more mathematical versions of important aspects are included for those who desire them. The book also surveys geochemical constraints and mantle evolution. The audience for Geoff Davies' book will be the broad range of geologists who desire a better understanding of the earth's internal dynamics, as well as graduate students and researchers working on the many aspects of mantle dynamics and its implications for geological processes. It is also suitable as a text or supplementary text for upper undergraduate and postgraduate courses in geophysics, geochemistry, and tectonics.
