The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.
This book presents the research results of an interdisciplinary study on climate change policies by the Enforcing Environmental Policy (EEP) Network, a project supported by the Human Dimension Potential Programme. Contributions are from highly qualified economic and legal specialists based at research institutes across Europe. The book gives answers to several questions related to the implementation of the international rules on climate change, most notably the Kyoto Protocol. It analyses ways and means to facilitate and encourage compliance with the objectives of the Kyoto Protocol. It is addressed to policy-makers, academics, business-sector and stakeholders throughout and outside Europe. Due to its interdisciplinary approach, this work is a distinctive and unique product compared to the existing literature on the subject. The effective implementation of climate protection and clean air policy requires an understanding of the political, legal and economic structures and constraints facing policy makers - and this is exactly what this book offers.
An extensive volume of Sugarcane Diseases and their World Distribution (Vol. I) was published by Elsevier under the auspices of the International Society of Sugar Cane Technologists in 1961. The present volume was intended to be a new edition of the book, but so many changes were required that a new book was needed. Only three chapters have been kept with slight amendments. The other chapters have been completely re-written. In fact with changes in importance of major diseases, four diseases previously treated have been left out; on the other hand, three new topics have been included in the new book, two new diseases and a chapter on sugarcane quarantine. The first chapter gives a brief account of the anatomy, morphology and physiology of the sugarcane plant to facilitate terminology and especially for a better appreciation of the effect of disease on the growth of the crop. Diseases are extensively treated as in Volume I, with a very good description of their symptoms and variation under different conditions and severity, all well illustrated by black and white figures and in a set of colour plates at the end of the book which will prove of valuable help for identification. The causal agents of the diseases are described giving synonyms, cultural characteristics, isolation methods and present knowledge on race variation, an aspect on which there has been quite an advance in knowledge since Volume I was published. New techniques of diagnosis are also given. Advances in research on the diseases over the last 25 years are well covered and supported by an extensive bibliography at the end of each chapter. The book has been edited by people having first hand experience in the field and in research on these diseases. Authors have been selected from among the most knowledgeable all over the sugar cane world, especially with due regard to the importance of the different diseases in their countries. The book should prove of immense value to those concerned with practical aspects of plant disease control in the field: pathologists, agronomists and crop specialists, including consultants, to those concerned with quarantine of the crop, for university lectures and students, and research scientists. In a pre-publication review D.J. Heinz and S.A. Ferreira of the Hawaiian Sugar Planters' Association stated: ``Much has changed and new information generated since the original version of this book was published in 1961. This new edition incorporates most of it, providing both the laboratory and field sugarcane pathologist a complete and authoritative guide to the major sugarcane diseases of the world. It is the best single book available on sugarcane diseases.''
"The first approach can be called vertical since what is explored here is the human body's relationship to the divine, to the bestial and to the machines that imitate or simulate it. The second approach covers the various junctures between the body's "outside" and "inside": it can therefore be called a "psychosomatic" approach, studying the manifestation - or production - of soul and the expression of emotions through the body's attitudes, and, on another level, the speculations inspired by cenesthesia, pain and death. Finally, the third approach ... brings into play the classical opposition between organ and function by showing how a certain organ or bodily substance can be used to justify or challenge the way human society functions ..." - foreword Part 3.
Walter Lippmann wrote his "Public Opinion" at a time when something like the 'mass media' was coming into existence. Prior to the age of electronic communication, the only mechanism for reaching large numbers of individuals was the newspapers. In World War I, he saw how opportunistic nations used the newspapers to serve their often nefarious aims. Lippmann, however, believed that in the hands of super-intelligent, disinterested, omni-benevelont 'experts, ' the 'mass media' could bring about world peace. The school system, the advent of radio, and of course, the television, were arriving or coming along shortly. Each allowed a small group of people the ability to manage a much larger group, inspiring optimism among liberals and progressives that with the right forumula, the horrors seen in World War I would never occur again. Lippmann wrote "Public Opinion" in 1922, shortly after World War I. In 1924, a certain Adolf Hitler would be spending time in jail. If this merited any mention in any newspaper, it is doubtful that no expert paid it any mind. 1939 was, after all, a long way off.

This paper develops a model based on Schumpeter's process of creative destruction. It departs from existing models of endogenous growth in emphasizing obsolescence of old technologies induced by the accumulation of knowledge and the resulting process or industrial innovations. This has both positive and normative implications for growth. In positive terms, the prospect of a high level of research in the future can deter research today by threatening the fruits of that research with rapid obsolescence. In normative terms, obsolescence creates a negative externality from innovations, and hence a tendency for laissez-faire economies to generate too many innovations, i.e too much growth. This "business-stealing" effect is partly compensated by the fact that innovations tend to be too small under laissez-faire. The model possesses a unique balanced growth equilibrium in which the log of GNP follows a random walk with drift. The size of the drift is the average growth rate of the economy and it is endogenous to the model ; in particular it depends on the size and likelihood of innovations resulting from research and also on the degree of market power available to an innovator.
Healthy seeds and propagules are the basic requirement for producing good grains, fruits and vegetables needed for human survival and perpetuation. Dispersal of microbial plant pathogens via seeds and propagules has assumed more importance than other modes of dispersal, as infected seeds and propagules have the potential to become the primary sources of carrying pathogen inoculum for subsequent crops. Several diseases transmitted through seeds and propagules have been shown to have the potential to damage economies as a result of huge quantitative and qualitative losses in numerous crops. Hence, it is essential to rapidly detect, identify and differentiate the microbial plant pathogens present in seeds and propagules precisely and reliably, using sensitive techniques. Microbial Plant Pathogens: Detection and Management in Seeds and Propagules provides a comprehensive resource on seed-borne and propagule-borne pathogens. Information on the biology of microbial pathogens, including genetic diversity, infection process and survival mechanisms of pathogens and epidemiology of diseases caused by them, are discussed critically and in detail to highlight weak links in the life cycles of the pathogens. Development of effective disease management systems, based on the principles of exclusion and eradication of pathogens and immunization of crop plants to enhance the levels of resistance of cultivars to diseases, has been effective to keep the pathogens at bay. The need for production of disease-free seeds/propagules has been emphasized to prevent the carryover of the inoculum to the next crop or introduction of the pathogens to other locations. Effectiveness of adopting simple cultural practices and development of cultivars resistant to diseases through traditional breeding methods or biotechnological approach have resulted in reducing the pathogen inoculum and disease incidence. Although application of different chemicals may reduce the disease incidence effectively, biological management of crop diseases, employing potential biological control agents have to be preferred to preserve the agroecosystems. Greater efforts have to be made to integrate compatible strategies to enhance the effectiveness of diseases management systems. Protocols appended at the end of relevant chapters form a unique feature of this book to enable the researchers to fine-tune their projects. This 2 volume set provides comprehensive and updated information about the economically-important groups of microbial plant pathogens carried by seed and propagules. Graduate students, researchers and teachers of plant pathology, plant protection, microbiology, plant breeding and genetics, agriculture and horticulture, as well as certification and quarantine personnel will find the information presented in this book useful.
