Optical communications networks are becoming increasingly important as there is demand for high capacity links. Dense wavelength division multiplexing (DWDM) is widely deployed at the core networks to accommodate high capacity transport systems. Optical components such as optical amplifiers, tunable filters, transceivers, termination devices and add-drop multiplexers are becoming more reliable and affordable. Access and metropolitan area networks are increasingly built with optical technologies to overcome the electronic bottleneck at network edges. New components and subsystems for very high speed optical networks offer new design options.The proceedings of the First International Conference on Optical Communications and Networks present high quality recent research results in the areas of optical communications, network components, architectures, protocols, planning, design, management and operation.

Now in use at over 300 colleges and universities, Essentials of Global Health is the first comprehensive text designed for introductory, undergraduate global health courses at two and four year colleges, as well those enrolled in online learning and others new to the field. Essentials of Global Health is a clear, concise, and user-friendly introduction to the most critical issues in global health. It illustrates key themes with an extensive set of case studies, examples, and the latest evidence. While the book offers a global perspective, particular attention is given to the health-development link, to developing countries, and to the health needs of poor and disadvantaged people. Essentials of Global Health builds on the success of an introductory global health course taught by the author at the George Washington School of Public Health and Health Services. Essentials of Global Health is ideal suited for the the Association of American Colleges and Universities recommended course: Global Health 101. Richard Skolnik is the winner of numerous honors for teaching, has taught global health for 8 years, and has more than 30 years of experience as a global health practitioner in multilateral, university, and NGO settings. He has been actively involved in dealing with critical issues in global health at country level and at the highest levels of international health policy making. Learn more about the author. “Richard Skolnik's Essentials of Global Health is so comprehensive that it will be key reading in international health. In accessible language, he explains why good health is crucial to economic development, what indicators help track changes in global health, and requirements for good health systems. Approaches to solving world health problems must be under pinned by good ethics and human rights guidelines, he says, and local practices and cultures must not be ignored. Skolnik looks in detail at children's and women's health, and at the different challenges of tackling communicative and non-communicative disease in developing countries. He also maps out the key players in global health and looks ahead to future challenges.” —The Lancet, October 2007 The book is organized in four parts: - Principles, Measurements, and the Health-Development Link: The principles of Global Health; Health Determinants, Measurements, and Trends; and Health, Education, Poverty, and the Economy. - Cross-Cutting Global Health Themes: Human Rights, Ethics, and Global Health; An Introduction to Health Systems; and Culture and Health. - The Burden of Disease: The Environment and Health; Nutrition and Health; Women’s Health; Child Health; Infectious Diseases; Non-Communicable Diseases; and Unintentional Injuries. - Working Together to Improve Global Health: Conflicts, Natural Disasters, and Other Emergencies; Cooperating to Improve Global Health; and, Science Technology, and the Public’s Health.” Instructor Resources - Detailed Syllabus, updated each semester - Test

The world's demand for food is expected to double within the next 50 years, while the natural resources that sustain agriculture will become increasingly scarce, degraded, and vulnerable to the effects of climate change. In many poor countries, agriculture accounts for at least 40 percent of GDP and 80 percent of employment. At the same time, about 70 percent of the world's poor live in rural areas and most depend on agriculture for their livelihoods. 'World Development Report 2008' seeks to assess where, when, and how agriculture can be an effective instrument for economic development, especially development that favors the poor. It examines several broad questions: How has agriculture changed in developing countries in the past 20 years? What are the important new challenges and opportunities for agriculture? Which new sources of agricultural growth can be captured cost effectively in particular in poor countries with large agricultural sectors as in Africa? How can agricultural growth be made more effective for poverty reduction? How can governments facilitate the transition of large populations out of agriculture, without simply transferring the burden of rural poverty to urban areas? How can the natural resource endowment for agriculture be protected? How can agriculture's negative environmental effects be contained? This year's report marks the 30th year the World Bank has been publishing the 'World Development Report'.
