Improvement of the world's livestock industry necessitates input from many directions. Planning by a host of national and international agencies is required in order to provide optimal stimulus in very diverse areas ranging from formulation of laws and incentives that stimulate competition yet prevent undue competition, to the optimal provision of credit. Planning is needed to carry out a complex array of interrelated research. The purpose of this book is specifically tasked with setting forth frameworks and methods for evaluation of investments and associated economic decision-making in the livestock industries of developing countries. Economists will find this book useful because it synthesizes .much material into a cohesive whole--material that is often presented in a cursory manner or overlooked as emphasis has shifted to sophisticated quantitative techniques.

"The nations of Subsaharan Africa experienced declining levels of food production per capita throughout the 1970s and early 1980s, particularly in the area of livestock production. Addressing that problem, the authors of this book assess in a systems context the environmental, biological, and social constraints on future African livestock development and consider prospects for improving productivity, They focus especially on changes needed in production and marketing systems, pointing to important policy considerations . The book is divided into four parts containing twenty-one chapters, each authored by one or more respective authorities in his or her field. Each section in its own way addresses the entire set of questions; topics include aspects of animal breeding and nutrition, anthropology, economics, ecology, farming systems, governmental policy, land tenure, marketing, modelling, and veterinary medicine."

The Japanese Cattle industry has been undergoing major changes for the past three decades. During the 1950's and 1960's mechanized power rapidly. The process of beef industry structure change accelerated in the 1970's as medium scale feedlots came into being, regional packing plants were established, and the beef marketing system matured. Economic forces, both within and external to the industry. A major objective of this book is to test the authors' hypothesis that beef production by Japan's cattle industry could become competitive with imported beef.

Scholars and analysts seeking to illuminate the extraordinary creativity and innovation evident in European medieval cultures and their afterlives have thus far neglected the important role of religious heresy. The papers collected here - reflecting the disciplines of history, literature, theology, philosophy, economics and law - examine the intellectual and social investments characteristic of both deliberate religious dissent such as the Cathars of Languedoc, the Balkan Bogomils, the Hussites of Bohemia and those who knowingly or unknowingly bent or broke the rules, creating their own 'unofficial orthodoxies'. Attempts to understand, police and eradicate all these, through methods such as the Inquisition, required no less ingenuity. The ambivalent dynamic evident in the tensions between coercion and dissent is still recognisable and productive in the world today.

Trees provide many valuable ecosystem services: they reduce energy consumption, they trap and filter stormwater, they help clean the air by intercepting air pollutants, and they help in the fight against global climate change by sequestering carbon dioxide (CO2). At the same time, they provide a wide array of aesthetic, social, economic, and health benefits that are less tangible.

The Million Trees LA initiative intends to chart a course for sustainable growth through planting and stewardship of trees. The purpose of this study was to measure Los Angeles's existing tree canopy cover (TCC), determine if space exists for 1 million additional trees, and estimate future benefits from the planting. Highresolution QuickBird remote sensing data, aerial photographs, and geographic information systems were used to classify land cover types, measure TCC, and identify potential tree planting sites. Benefits were forecast for planting of 1 million trees between 2006 and 2010, and their growth and mortality were projected until 2040. Two scenarios reflected low (17 percent) and high (56 percent) mortality rates. Numerical models were used with geographic data and tree size information for coastal and inland climate zones to calculate annual benefits and their monetary value. Los Angeles's existing TCC was 21 percent, and ranged from 7 to 37 percent by council district. There is potential to add 2.5 million additional trees to the existing population of approximately 10.8 million, but only 1.3 million of the potential tree sites are deemed realistic to plant. Thus, there is space for planting 1 million new trees. Benefits for the 1-million-tree planting for the 35-year period were $1.33 billion and $1.95 billion for the high- and low-mortality scenarios, respectively. Average annual benefits were $38 and $56 per tree planted. Eighty-one percent of total benefits were aesthetic/other, 8 percent were stormwater runoff reduction, 6 percent energy savings, 4 percent air quality improvement, and less than 1 percent atmospheric carbon reduction. Recommendations included developing a decision support tool for tree selection and tracking, as well as establishing a model parking lot greening program.

Trees make our cities more attractive and provide many ecosystem services, including air quality improvement, energy conservation, stormwater interception, and atmospheric carbon dioxide reduction. These benefits must be weighed against the costs of maintaining trees, including planting, pruning, irrigation, administration, pest control, liability, cleanup, and removal. We present benefits and costs for representative small, medium, and large broadleaf trees and a conifer in the Central Florida region derived from models based on research carried out in Orlando, Florida. Average annual net benefits increase with tree size and differed based on locations. Two hypothetical examples of planting projects are described to illustrate how the data in this guide can be adapted to local uses, and guidelines for maximizing benefits and reducing costs are given.

Even as they increase the beauty of our surroundings, trees provide us with a great many ecosystem services, including air quality improvement, energy conservation, stormwater interception, and atmospheric carbon dioxide reduction. These benefits must be weighed against the costs of maintaining trees, including planting, pruning, irrigation, administration, pest control, liability, cleanup, and removal. We present benefits and costs for representative small, medium, and large deciduous trees in the Lower Midwest region derived from models based on in-depth research carried out in Indianapolis, Indiana. Average annual net benefits increase with tree size and differ based on location. Two hypothetical examples of planting projects are described to illustrate how the data in this guide can be adapted to local uses, and guidelines for maximizing benefits and reducing costs are given.

Drawing on a range of approaches in cultural, gender and literary studies, this book presents Chretien de Troyes's Erec et Enide as a daring and playful exploration of scandal, terror and anxiety in court cultures. Through an interdisciplinary reading, it locates Erec et Enide, the first surviving Arthurian romance in French, in various contexts, from broad cultural and historical questionings such as medieval vernacular 'modernity's' engagement with the weight of its classical inheritance, to the culturally fecund and politically turbulent histories of the families of Eleanor of Aquitaine and Henry II Plantagenet. Where previous accounts of the tale have not uncommonly presented Chretien's poem as a decorous 'resolution' of tensions between dynastic marriage and fin'amors, between personal desire and social duty, this reading sees these forces as in permanent and irresolvable tension, the poem's key scenes haunted - whether mischievously or traumatically - by questions and skeletons from various closets.

Oxford, Bern, Berlin, Bruxelles, Frankfurt/M., New York, Wien. This book offers detailed and provocative readings of a range of medieval French texts (chansons de geste from the cycle du roi, the verse Ovide moralise and the trickster narrative, Trubert), aiming to illustrate how the ideas of Jacques Lacan and Slavoj Zizek can be applied to works from this period. By means of this approach, it aims to throw new light on the manner in which different works define, elaborate and undermine their respective visions of literary, communal and historical identity.
