The publication of Murdock's Ethnographic Atlas in 1967 marked the first time that descriptive information on the peoples of the world—primitive, historical, and contemporary—had been systematically organized for the purposes of comparative research. In this volume, Murdock has completely revised this work, selecting 563 societies that are most fully and accurately described in ethnographic literature. The identification of each society gives its geographical coordinates and date, its identifying number in the Ethnographic Atlas, and an indication of whether it is included in the Human Relations Area Files or the Standard Cross-Cultural Sample. In addition, bibliographical references are offered for each society. The information and suggested research techniques will be of value to comparativists in anthropology, history, political science, psychology and sociology. Most importantly, it offers a simple method fro choosing a valid sample of the world's known societies for cross-cultural research.
Field Crop Arthropod Pests of Economic Importance presents detailed descriptions of the biology and ecology of important arthropod pest of selected global field crops. Standard management options for insect pest control on crops include biological, non-chemical, and chemical approaches. However, because agricultural crops face a wide range of insect pests throughout the year, it can prove difficult to find a simple solution to insect pest control in many, if not most, cropping systems. A whole-farm or integrated pest management approach combines cultural, natural, and chemical controls to maintain insect pest populations below levels that cause economic damage to the crop. This practice requires accurate species identification and thorough knowledge of the biology and ecology of the target organism. Integration and effective use of various control components is often enhanced when the target organism is correctly identified, and its biology and ecology are known. This book provides a key resource toward that identification and understanding. Students and professionals in agronomy, insect detection and survey, and economic entomology will find the book a valuable learning aid and resource tool. - Includes insect synonyms, common names, and geographic distribution - Provides information on natural enemies - Is thoroughly referenced for future research
Weeds affect everyone in the world by reducing crop yield and crop quality, delaying or interfering with harvesting, interfering with animal feeding (including poisoning), reducing animal health, preventing water flow, as plant parasites, etc. Weeds are common everywhere and cause many $ billions worth of crop losses annually, with the global cost of controlling weeds running into $ billions. The anatomy of plants is generally well understood, but the examples used for explanations in most books are often restricted to non-weed species. Weeds have many features that make them more competitive, for example enabling them to more quickly recover after herbicide treatment. Some of these adaptations include rhizomes, adapted roots, tubers and other special structures. Until now, no single book has concentrated on weeds’ anatomical features. A comprehensive understanding of these features is, however, often imperative to the successful implementation of many weed control measures. Beautifully and comprehensively illustrated, in full colour throughout, Weed Anatomy provides a comprehensive insight into the anatomy of the globally-important weeds of commercial significance. Commencing with a general overview of anatomy, the major part of the book then includes sections covering monocotyledons, dicotyledons, brackens and horsetails, with special reference to their anatomy. Ecological and evolutionary aspects of weeds are also covered and a number of less common weeds such as Adonis vernalis, Caucalis platycarpos and Scandix pecten-veneris are also included. The authors of this book, who have between them many years of experience studying weeds, have put together a true landmark publication, providing a huge wealth of commercially-important information. Weed scientists, plant anatomists and agricultural scientists, including personnel within the agrochemical and crop protection industry, will find a great deal of useful information within the book’s covers. All libraries in universities and research establishments where agricultural and biological sciences are studied and taught should have copies of this exceptional book on their shelves.

Each chapter addresses the main breeding objectives, markets served, current breeding approaches, biotechnology, genetic progress observed, and in addition a glimpse into the future for each of these selected and important tropical crops.
Peter Balakian is a renowned poet, scholar, and memoirist; but his work as an essayist often prefigures and illuminates all three. "I think of vise and shadow as two dimensions of the lyric (literary and visual) imagination," he writes in the preface to this collection, which brings together essayistic writings produced over the course of twenty-five years. Vise, "as in grabbing and holding with pressure," but also in the sense of the vise-grip of the imagination, which can yield both clarity and knowledge. Consider the vise-grip of some of the poems of our best lyric poets, how language might be put under pressure "as carbon might be put under pressure to create a diamond." And shadow, the second half of the title: both as noun, "the shaded or darker portion of the picture or view or perspective," "partial illumination and partial darkness"; and as verb, to shadow, "to trail secretly as an inseparable companion" or a "force that follows something with fidelity; to cast a dark light on something—a person, an event, an object, a form in nature." Vise and Shadow draws into conversation such disparate figures as W. B. Yeats, Hart Crane, Joan Didion, Primo Levi, Robert Rauschenberg, Bob Dylan, Elia Kazan, and Arshile Gorky, revealing how the lyric imagination of these artists grips experience, "shadows history," and "casts its own type of illumination," creating one of the deepest kinds of human knowledge and sober truth. In these elegantly written essays, Balakian offers a fresh way to think about the power of poetry, art, and the lyrical imagination as well as history, trauma, and memory.

The world's 58 poorest countries are diverse in many respects, but they share the characteristic of a labor force overwhelmingly dependent on agriculture. Challenging the assumption that mass poverty and chronic hunger are insoluble problems, this book systematically explores the multiple aspects of economic development in these countries, which are home to 60 percent of the world's population. The authors offer a broad-based development strategy to raise incomes through agricultural productivity growth and expanded rural employment. They present rich new information on the rural informal sector and on agriculture-industry interactions, and they analyze the impact of macroeconomic and social policies on the rural economy. Policy instruments aimed at bringing about broad-based development are carefully assessed from fiscal policy to development of hew seeds and farm implements. The book includes detailed case studies of countries that have seized—or missed—development opportunities. Comparison of the successful economic transformations of Japan and the United States shows how key ideas, which the authors call strategic notions, have enabled policymakers to act with foresight. Analyses of strategic choices in China, the Soviet Union, Taiwan, Mexico, Kenya, and Tanzania also show how development strategies that emerge from the real-world political economy reflect a mix of individual interests and strategic notions.
