Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.

Around the turn of the millennium it had become painfully evident that development aid, charity or "global business-as-usual" were not going to be the mechanisms to alleviate global poverty. Today, there is little dispute that poverty remains the most pressing global problem calling for innovative solutions. One recent strategy is the Base of the Pyramid (BoP) concept developed by Prahalad and Hart, which relies on entrepreneurial activity tapping into the previously ignored markets of the economically most disadvantaged. It is a process requiring innovations in several disciplines: technological, social and business.This book covers a number of areas. First, much of the current BoP discussion emphasises targeting products to the needs of the poor. But do we actually know what the real needs of the poor are? This book takes a bottom-up human-centred approach and examines examples that truly engage the poor in BoP product and service development. What types of needs assessment methodologies are indicated considering the cultural differences in BoP countries? Are the existing methodologies adequate? Do they need to be redefined and redeveloped? Second, the book considers how we can balance poverty alleviation and stimulate economic growth without stressing the ecosystem. Tragically, the poor are hardest hit by the adverse effects of environmental deterioration such as water shortages, climate change or the destruction of habitats. While the economic welfare of the poor is critical, the BoP approach must balance its inherent paradox of encouraging greater consumption while avoiding further pressures on environmental sustainability. The link between the BoP approach and sustainable development is a key feature of this book. Third, it looks at innovation and asks what kinds of"bottom-up" innovation (open source, technological, social and business) support BoP initiatives (and sustainable development)?Fourth, the book deals with the relationship between development assistance and BoP. Is a BoP strategy the antithesis to development aid or can these two co-exist or even complement each other?Finally, the book raises questions about the relationship between corporate responsibility and BoP. Is BoP a new form of corporate neo-colonialism or a new form of corporate responsibility? Although the BoP concept has unleashed an extensive and generally enthusiastic response from academics, businesses, NGOs and governments, the knowledge domain around this concept is still in the early stages of development. This book addresses that need with a focus on the needs of the end-users – the poor – as a starting point for BoP products and innovations. With contributions from both supporters and critics, it provides a treasure trove of global knowledge on how the concept has developed, what its successes and failures have been and what promise it holds as a long-term strategy for alleviating poverty and tackling global sustainability.

Separation processes—or processes that use physical, chemical, or electrical forces to isolate or concentrate selected constituents of a mixture—are essential to the chemical, petroleum refining, and materials processing industries. In this volume, an expert panel reviews the separation process needs of seven industries and identifies technologies that hold promise for meeting these needs, as well as key technologies that could enable separations. In addition, the book recommends criteria for the selection of separations research projects for the Department of Energy's Office of Industrial Technology.
