Gauss's law for electric fields, Gauss's law for magnetic fields, Faraday's law, and the Ampere–Maxwell law are four of the most influential equations in science. In this guide for students, each equation is the subject of an entire chapter, with detailed, plain-language explanations of the physical meaning of each symbol in the equation, for both the integral and differential forms. The final chapter shows how Maxwell's equations may be combined to produce the wave equation, the basis for the electromagnetic theory of light. This book is a wonderful resource for undergraduate and graduate courses in electromagnetism and electromagnetics. A website hosted by the author at www.cambridge.org/9780521701471 contains interactive solutions to every problem in the text as well as audio podcasts to walk students through each chapter.
Some 250,000 people died in the southern Somalia famine of 2011-12, which also displaced and destroyed the livelihoods of hundreds of thousands more. Yet this crisis had been predicted nearly a year earlier. The harshest drought in Somalia's recent history coincided with a global spike in food prices, hitting this arid, import-dependent country hard. The policies of Al-Shabaab, a militant Islamist group that controlled southern Somalia, exacerbated an already difficult situation, barring most humanitarian assistance, while donors counter-terrorism policies led to cuts and criminalized any aid falling into their hands. A major disaster resulted from the production and market failures precipit...
This book analyzes the impact food aid programmes have had over the past fifty years, assessing the current situation as well as future prospects. Issues such as political expediency, the impact of international trade and exchange rates are put under the microscope to provide the reader with a greater understanding of this important subject matter. This book will prove vital to students of development economics and development studies and those working in the field.
TRENDS IN LINGUISTICS is a series of books that open new perspectives in our understanding of language. The series publishes state-of-the-art work on core areas of linguistics across theoretical frameworks as well as studies that provide new insights by building bridges to neighbouring fields such as neuroscience and cognitive science. TRENDS IN LINGUISTICS considers itself a forum for cutting-edge research based on solid empirical data on language in its various manifestations, including sign languages. It regards linguistic variation in its synchronic and diachronic dimensions as well as in its social contexts as important sources of insight for a better understanding of the design of linguistic systems and the ecology and evolution of language. TRENDS IN LINGUISTICS publishes monographs and outstanding dissertations as well as edited volumes, which provide the opportunity to address controversial topics from different empirical and theoretical viewpoints. High quality standards are ensured through anonymous reviewing.
Providing a critical introduction to the notion of humanitarianism in global politics, tracing the concept from its origins to the twenty-first century, this book examines how the so called international community works in response to humanitarian crises and the systems that bind and divide them. By tracing the history on international humanitarian action from its early roots through the birth of the Red Cross to the beginning of the UN, Peter Walker and Daniel G. Maxwell examine the challenges humanitarian agencies face, from working alongside armies and terrorists to witnessing genocide. They argue that humanitarianism has a vital future, but only if those practicing it choose to make it so. Topics covered include: the rise in humanitarian action as a political tool the growing call for accountability of agencies the switch of NGOs from bit players to major trans-national actors the conflict between political action and humanitarian action when it comes to addressing causes as well as symptoms of crisis. This book is essential reading for anyone with an interest in international human rights law, disaster management and international relations.
Researchers in developing countries often find that the particular country in which they work presents a range of unforeseen challenges. Indeed, their ability to carry out effective scholarship is often highly dependent on these factors. The great differences between working in countries as varied as India, China, Bolivia and Kenya can often come as a shock to the system. An ability to negotiate a bewildering array of cultural and logistical obstacles is therefore essential. Overseas Research II: A Practical Guide distils essential lessons learned by scores of students and scholars who have collected data and done fieldwork abroad. The authors fill the reader in on the many crucial pieces of...
When conducting research in developing countries, an ability to negotiate a bewildering array of cultural and logistical obstacles is essential. Overseas Research: A Practical Guide distills essential lessons from scores of students and scholars who have collected data and done fieldwork abroad, including how to prepare for the field, how and where to find funding for one’s fieldwork, issues of personal safety and security, and myriad logistical and relational issues. By encouraging researchers to think through the challenges of research before they begin it, Overseas Research will help prepare fieldworkers for the practical, logistical, and psychological considerations of very demanding w...
