Sommario/riassunto |

Volatile organic solvents are the normal media used in both research scale and industrial scale synthesis of organic chemicals. Their environmental impact is significant, however, and so the development of alternative reaction media has become of great interest.Developments in the use of water as a solvent for organic synthesis have reached the point where it could now be considered a viable solvent for many organic reactions. Organic Reactions in Water demonstrates the underlying principles of using water as a reaction solvent and, by reference to a range of reaction types and systems |

Sommario/riassunto |

"Although more children than ever before are now enrolled in school, in the global South a good quality education remains out of reach for all except a privileged few. Most pupils experience inadequately prepared and poorly motivated teachers struggling to deliver new and complex curricula with insufficient learning resources in overcrowded classrooms, often using language that neither learners nor teachers speak outside school. For these learners, a good quality education must be a socially just education that is inclusive, relevant and democratic. It must develop the capabilities of learners to promote economic growth, create sustainable livelihoods, contribute to peaceful and democratic societies and achieve individual wellbeing. This in turn requires developing the professional capabilities of teachers and leaders.This book includes contributions from leading scholars in the field of education and development. It draws on state of the art evidence from the five year EdQual research programme on implementing education quality in low income countries and other relevant research. Through exploring recent initiatives in areas such as the curriculum, the use of ICTs, language and literacy, school effectiveness and leadership, the contributions go beyond looking at inputs and outputs for good quality education to open up the black box of the classroom and explore how practices of teaching and learning impact on different groups of learners. Some of the cross-cutting themes explored include defining quality, gender, inclusion, taking successful initiatives to scale and planning for both quality and equality. Education Quality and Social Justice in the Global South will appeal to undergraduate and postgraduate students and researchers within the fields of international and comparative education, teacher education, educational policy, poverty and development studies, African and Asian studies and related |

Sommario/riassunto |

Science and the University investigates the tremendous changes that have taken place in university research over the past several decades, gauging the current state of research in higher education and examining issues and challenges crucial to its future. Scientific research increasingly dominates the aims and agendas of many American universities, and this proliferation-and changes in the way research is conducted-has given rise to important questions about the interrelations of higher education, funding for scientific research, and government policy. The cost of doing science, the commercialization of university research, the changing composition and number of Ph.D. students, the effect of scientific research on other university programs-these are just a few of the many issues explored in this volume from the vantage points of scholars in such diverse fields as economics, biochemistry, genetics, and labor studies. |
