"There are two important facts which need to be remembered about e-Learning. The first is that there has seldom been a subject more fashionable and the second is that there has seldom been a subject which is more open to misunderstanding. It is obvious to nearly everyone that education throughout the world is under pressure to change. Education is expensive, or even education is extremely expensive. As the world transforms from highly individualist economies into economies that want to be regarded as global players so the demand for education soars. As the demand grows so does the cost of delivery. Now we talk about mass education which scares some of the older members of the education establishment.There are few people today who would oppose the view that e-learning has to become an integral part of the education of the future. And indeed, when e-Learning is correctly employed it can be highly effective and cost efficient." --Back cover.
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.
It is only recently that the immense economic value of pollination to agriculture has been appreciated. At the same time, the alarming collapse in populations of bees and other pollinators has highlighted the urgency of addressing this issue. This book focuses on the specific measures and practices that the emerging science of pollination ecology is identifying to conserve and promote animal pollinators in agroecosystems. It reviews the expanding knowledge base on pollination services, providing evidence to document the status, trends and importance of pollinators to sustainable agricultural production. It provides practical and specific measures that land managers can undertake to ensure that agroecosystems are supportive and friendly to pollinators. It draws on the Global Pollination Project, supported by UNEP/GEF and implemented by FAO and seven partner countries (Brazil, Ghana, India, Kenya, Nepal, Pakistan and South Africa), which serve to provide "lessons from the field".
This book draws on extensive research to provide a ground-breaking new account of the relationship between dialogue and children’s learning development. It closely relates the research findings to real-life classrooms, so that it is of practical value to teachers and students concerned that their children are offered the best possible learning opportunities. The authors provide a clear, accessible and well-illustrated case for the importance of dialogue in children's intellectual development and support this with a new and more educationally relevant version of socio-cultural theory, which explains the fascinating relationship between dialogues and learning. In educational terms, a sociocu...

The purpose of this collection is to guide the non-specialist through the basic theory of various generalizations of topology, starting with clear motivations for their introduction. Structures considered include closure spaces, convergence spaces, proximity spaces, quasi-uniform spaces, merotopic spaces, nearness and filter spaces, semi-uniform convergence spaces, and approach spaces. Each chapter is self-contained and accessible to the graduate student, and focuses on motivations to introduce the generalization of topologies considered, presenting examples where desirable properties are not present in the realm of topologies and the problem is remedied in the more general context. Then, enough material will be covered to prepare the reader for more advanced papers on the topic. While category theory is not the focus of the book, it is a convenient language to study these structures and, while kept as a tool rather than an object of study, will be used throughout the book. For this reason, the book contains an introductory chapter on categorical topology.
Written by a team from the U.S. Army's Combat Feeding Directorate at the Natick Research, Development and Engineering Center, this technical volume represents a comprehensive guide to how the military designs, processes, customizes, packages and distributes highly palatable, long shelf-life food products for field personnel. The book offers new data on numerous technologies used to solve problems such as nutrient densification, lightweighting, novel thermal processing, and long-term quality preservation in delivering appetizing foods and more. Testing techniques are explained for evaluating sensory qualities of foods and their effects on physical and cognitive performance.
