This book addresses the thorny and fascinating question of how food and voucher programs, despite theory and evidence generally favoring cash, remain relevant, have evolved, and, in most circumstances, have improved over time. In doing so, we take an evolutionary and pragmatic view; we are interested in understanding why food-based programs exist and how countries can benefit from transformations such as that of Chhattisgarh, not in determining whether those programs should exist.

The strengths and abilities children develop from infancy through adolescence are crucial for their physical, emotional, and cognitive growth, which in turn help them to achieve success in school and to become responsible, economically self-sufficient, and healthy adults. Capable, responsible, and healthy adults are clearly the foundation of a well-functioning and prosperous society, yet America's future is not as secure as it could be because millions of American children live in families with incomes below the poverty line. A wealth of evidence suggests that a lack of adequate economic resources for families with children compromises these children's ability to grow and achieve adult success, hurting them and the broader society. A Roadmap to Reducing Child Poverty reviews the research on linkages between child poverty and child well-being, and analyzes the poverty-reducing effects of major assistance programs directed at children and families. This report also provides policy and program recommendations for reducing the number of children living in poverty in the United States by half within 10 years.

This timely collection will be the first of its kind to focus on the practical application of the government job guarantee (JG) for both developed and developing economies. Global case studies include: United States, China, Ghana, Argentina, Ireland, Iceland, and India.

In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.

This book develops the mathematical tools essential for students in the life sciences to describe interacting systems and predict their behavior. From predator-prey populations in an ecosystem, to hormone regulation within the body, the natural world abounds in dynamical systems that affect us profoundly. Complex feedback relations and counter-intuitive responses are common in nature; this book develops the quantitative skills needed to explore these interactions. Differential equations are the natural mathematical tool for quantifying change, and are the driving force throughout this book. The use of Euler’s method makes nonlinear examples tractable and accessible to a broad spectrum of early-stage undergraduates, thus providing a practical alternative to the procedural approach of a traditional Calculus curriculum. Tools are developed within numerous, relevant examples, with an emphasis on the construction, evaluation, and interpretation of mathematical models throughout. Encountering these concepts in context, students learn not only quantitative techniques, but how to bridge between biological and mathematical ways of thinking. Examples range broadly, exploring the dynamics of neurons and the immune system, through to population dynamics and the Google PageRank algorithm. Each scenario relies only on an interest in the natural world; no biological expertise is assumed of student or instructor. Building on a single prerequisite of Precalculus, the book suits a two-quarter sequence for first or second year undergraduates, and meets the mathematical requirements of medical school entry. The later material provides opportunities for more advanced students in both mathematics and life sciences to revisit theoretical knowledge in a rich, real-world framework. In all cases, the focus is clear: how does the math help us understand the science?

This book enables teachers to develop a complete range of basic investigations for science with students aged five to 11 years. It demonstrates how children can use hands-on activities to consolidate and extend their knowledge and understanding. Investigations are presented in a generic form, so that teachers can work through them and adapt them to meet the particular needs of their own classes. The presentation of activities ranges from highly-structured sequences of instructions and questions (with answers!), to more general discussions, depending on the approach needed and the likely variations in equipment and materials available. Each activity is aimed to help any teacher carry out significant scientific investigations with their class, and where necessary, to learn alongside them. - Almost every investigation and activity has been tested by the author. - Investigations use readily-available, non-specialist or recycled materials. The context of this book is children′s need to learn through first-hand experience of the world around them. This book is an essential resource for teachers planning an effective science programme, or for student teachers needing to broaden their scientific knowledge and understanding. 200 Science Investigations for Young Students is the companion volume of activities which demonstrate the theories in Martin Wenham′s Understanding Primary Science. The content has been guided by, but not limited to, The National Curriculum 2000 and the Initial Teacher Training Curriculum for Primary Science, issued by the Teacher Training Agency.
