[{"$nulls":4},"decades. The purpose of the book is to introduce the fundamentals and applications of optimum structural design. Much work has been done in this area recently and many studies have been published. The book is an attempt to collect together selected topics of this literature and to present them in a unified approach. It meets the need for an introductory text covering the basic concepts of modem structural optimization. A previous book by the author on this subject (\"Optimum Structural Design\". published by McGraw-Hill New York in 1981 and by Maruzen Tokyo in 1983). has been used extensively as a text in many universities throughout the world. The present book reflects the rapid progress and recent developments in this area. A major difficulty in studying structural optimization is that integration of concepts used in several areas. such as structural analysis. numerical optimization and engineering design. is necessary in order to solve a specific problem. To facilitate the study of these topics. the book discusses in detail alternative problem formulations. the fundamentals of different optimization methods and various considerations related to structural design. The advantages and the limitations of the presented approaches are illustrated by numerous examples."]

[null,null,null,"Sommario/riassunto","Amerindian societies have an iconic status in classical political thought. For Montaigne, Hobbes, Locke, Hume and Rousseau, the native American ‘state of nature’ operates as a foil for the European polity. Challenging this tradition, The Imbalance of Power demonstrates ethnographically that the Carib speaking indigenous societies of the Guiana region of Amazonia do not fit conventional characterizations of ‘simple’ political units with ‘egalitarian’ political ideologies and ‘harmonious’ relationships with nature. Marc Brightman builds a persuasive and original theory of Amerindian politics: far from balanced "]

The Imbalance of Power is based on the author’s fieldwork in partnership with Vanessa Grotti, who is working on a companion volume entitled Living with the Enemy: First Contacts and the Making of Christian Bodies in Amazonia."]
