  • Agricultural Policy Formation in the European Community

    The Birth of Milk Quotas and CAP Reform
    • 1 Edición
    • Volumen 4
    • M. Petit + 5 más
    • Inglés
    Understanding why agricultural policies of developed countries are what they are is critical on several accounts for the developed countries as a group and for individual countries. It is important because the inter-dependencies among national agricultural policies are so numerous, as illustrated by the ongoing agricultural trade confrontation between the United States and the European Community; confrontation that is vividly expressed in the current subsidy war between the two trading blocs. The stakes for developing countries are also very high because the domestic agricultural policies of these two giants have a considerable influence on the international markets of major agricultural commodities.Studying why policies are what they are is an important research issue: legitimate in its own right on scientific grounds and relevant for any institution dealing with agricultural policies. Thus, it is only fitting that an international research institute dealing with food policy should analyze developed country policies and actions. This book is a further development of a research report by Michel Petit, ``Determinants of Agricultural Policies in the United States and the European Community'', published by the International Food Policy Research Institute (IFPRI), and is written by a team of eminent European scholars from a variety of organisations called together by Michel Petit and working under his leadership. Concentrating on the policy process in the European Community, this research provides useful insights on the influence of domestic, economic and political factors in shaping the positions of member countries in Community negotiations and on the process leading to a Community policy decision.

  • An Introduction to Animal Law

    • 1 Edición
    • Cooper
    • Inglés
    Legislation relating to animals has ancient origins and in many civilizations certain species have held particular significance, be it religious, cultural, nutritional, or sporting. As a general rule, the law was primarily concerned with animals as property, rather than in need of protection, until the 19th century. Since the 1970s animal law has proved to be a growth area in the production and enforcement of both national and international legislation. This has been particularly so in the areas of conservation and welfare and there has been extensive legal and philosophical consideration of the status of animals.This book is not intended to be a standard text, but rather a handbook in the true sense, a guide for the lay person--namely, to help the non-lawyer to understand the basic concepts of animal law and to provide the lawyer (who is the lay person in the world of animal science) with an introduction to relevant concepts and literature which are not normally found in the conventional legal texts.

    Rodent Malaria reviews significant findings concerning malaria parasites of rodents, including their taxonomy, zoogeography, and evolution, along with life cycles and morphology; genetics and biochemistry; and concomitant infections. This volume is organized into eight chapters and begins by sketching out the history of the discovery of rodent as well as aspects of parasitology, immunology, and chemotherapy. These concepts are investigated two decades following Ignace Vincke's major discovery and Meir Yoeli's successful establishment of the method of cyclical transmission of the parasite. The following chapters focus on the taxonomy and systematics of the subgenus Vinckeia, with reference to the concepts of species and subspecies of animals and the degree to which they apply to malaria parasites, in particular to those of rodents. The discussion then shifts to how the rodent malaria parasites provide a unique insight into the subcellular organization of Plasmodium species, the use of rodent malaria as an experimental model to study immunological responses, and infectious agents that interact with malaria parasites. The book concludes with a chapter on malaria chemotherapy, with emphasis on the value of rodent malaria in antimalarial drug screening and the use of antimalarial drugs as biological probes. This book will be of interest to protozoologists and physicians as well as those from other disciplines including biochemistry, immunology, pharmacology, cell biology, and genetics.
