Commodity Derivatives: A Guide for Future Practitioners describes the origins and uses of these important markets. Commodities are often used as inputs in the production of other products, and commodity prices are notoriously volatile. Derivatives include forwards, futures, options and swaps; all are types of contracts that allow buyers and sellers to establish the price at one time and exchange the commodity at another. These contracts can be used to establish a price now for a purchase or sale that will occur later, or establish a price later for a purchase or sale now. This book provides detailed examples for using derivatives to manage prices by hedging, using futures, options and swaps. It also presents strategies for using derivatives to speculate on price levels, relationships, volatility, and the passage of time. Finally, because the relationship between a commodity price and a derivative price is not constant, this book examines the impact of basis behavior on hedging results, and shows how the basis can be bought and sold like any other price. The material in this book is based on the author's 30-year career in commodity derivatives, and is essential reading for students planning careers as commodity merchandisers, traders, and related industry positions. Not only does it provide them with the necessary theoretical background, but it also covers the practical applications that employers expect new hires to understand. Examples are coordinated across chapters using consistent prices and formats, and uses industry terminology so students can become familiar with standard terms and concepts. This book is organized into 18 chapters, corresponding to approximately one chapter per week for courses on the semesters"--

"Some of the most pressing questions of our time concern how groups behave, from political polarization and cooperation to collective action, social influence and cultural evolution. This book is intended to equip scholars in the social, behavioral, and cognitive sciences with a toolkit for thinking about and studying social dynamics using mathematical and computational models. Currently, there are two approaches for modeling social dynamics: mathematical models and agent-based models. In this book, Smaldino treats the two traditions as complementary, rather than separate. Combining theory-driven instruction on key mathematical and agent-based models of social dynamics and cultural evolution with practical, specific examples of how to use models, the book offers an introduction to both kinds of modelling and shows readers how to build their own models, analyze them, and integrate them with empirical research.The book assumes minimal background in either programming or advanced mathematics"--

This book discusses ethical behavior through the genocidal stages of the Holocaust. Paul E. Wilson first looks at the antisemitism in Germany and Europe beginning in the decades preceding the Nazis reign of terror, and goes on to discuss the ethical decisions made in the initial stages that moved society toward genocide. The author maintains that the stages of genocide represent subtle changes that can be happening within a society in response to the moral choices made by actors. By giving attention to the stages of genocide in the Holocaust, this book contributes to the overall understanding of how the Holocaust was possible, and encourages the moral community to join the watch for the development of genocide in the modern world. Paul E. Wilson is Professor of Philosophy and Religion at Shaw University, USA

First published in 1984. As scholar, researcher, and commentator, Dr. Paul E. Zinner has spent much of the last six years in Europe studying the development of East-West relations, observing negotiations on arms reduction, and conducting interviews with foreign policy and national security experts from key countries. This book brings together eleven of his essays~-nearly all previously unpublished--that emphasize developments since 1977. The essays cover a broad range of topics, among them the status and prospects of the Vienna troops reduction talks; the political and military implications of NATO's "double track" decision concerning modernization of intermediate-range nuclear forces in Europe; the impact of the crises in Afghanistan and Poland on the Western alliance; and the foreign policy options available to the Reagan administration. Also included are assessments of current trends in the NATO alliance and a cautious projection of the political climate in Western Europe by the end of the 198Os. Updated throughout with introductory and commentary notes, the essays provide insight into the dominant themes in the interaction between the NATO and Warsaw Pact powers.

An engaging look at the ways economic thinking can help us understand how sports work both on and off the field Are ticket scalpers good for teams? Should parents push their kids to excel at sports? Why do Koreans dominate women's golf, while Kenyans and Ethiopians dominate marathon racing? Why would Michael Jordan, the greatest player in basketball, pass to Steve Kerr for the game-winning shot? Paul Oyer shows the many ways economics permeates the world of sports. His topics range from the business of sport to how great athletes use economic thinking to outsmart their opponents to why the world's greatest sports powerhouse (at least per capita) is not America or China but the principality of Liechtenstein. Economics explains why some sports cannot stop the use of performance-enhancing drugs while others can, why hundred-million-dollar player contracts are guaranteed in baseball but not in football, how one man was able to set the world of sports betting on its ear-and why it will probably never happen again. This book is an entertaining guide to how a bit of economics can make you a better athlete and a more informed fan

La 4e de couverture indique : "Ce livre est un ouvrage de référence dans l'historiographie internationale de l'esclavage. De façon argumentée, il démontre l'importance de l'esclavage dans l'histoire de l'Afrique et met en exergue un phénomène historique central qui a eu ses propres déclinaisons régionales et sa propre périodisation. S'appuyant sur de nombreuses archives, il montre que l'esclavage s'est transformé dans le temps sous l'effet d'influences externes à l'Afrique -principalement par la demande de la traite européenne et la traite islamique, puis par l'abolition européenne- et sous l'effet de dynamiques internes, à travers l'usage d'esclaves comme mode de production. Briser le silence sur les implications de l'esclavage dans l'histoire de l'Afrique : tel est l'objectif de ce livre. Paul Lovejoy est Professeur Distingué d'Histoire de l'Université de York, et ancien directeur de la Chaire de recherche canadienne sur l'histoire de la diaspora africaine. Il a été le fondateur et le directeur de l'Institut Harriet Tubman pour la recherche en Afrique et ses diasporas à l'Université de York. Auteur de plus de 30 ouvrages et 100 articles sur l'histoire de l'Afrique et de la diaspora africaine, dont Jihad in West Africa during the Age of Revolutions (2016) et Slavery, Memory, Citizenship (2016), avec Vanessa Oliveira, il est le rédacteur en chef de la Revue de l'Institut Tubman sur la diaspora africaine" (éditeur : Africa World Press) (éditeur)
