A fascinating account of how radical researchers have used experiments to overturn conventional wisdom and shaped life as we know it Experiments have consistently been used in the hard sciences, but in recent decades social scientists have adopted the practice. Randomized trials have been used to design policies to increase educational attainment, lower crime rates, elevate employment rates, and improve living standards among the poor. This book tells the stories of radical researchers who have used experiments to overturn conventional wisdom. From finding the cure for scurvy to discovering what policies really improve literacy rates, Leigh shows how randomistas have shaped life as we know it. Written in a “Gladwell-esque” style, this book provides a fascinating account of key randomized control trial studies from across the globe and the challenges that randomistas have faced in getting their studies accepted and their findings implemented. In telling these stories, Leigh draws out key lessons learned and shows the most effective way to conduct these trials.
Fruto de un encuentro celebrado en Vilanova i la Geltrú (España) en julio de 2002, el libro que presentamos hoy, trata uno de los temas de gran importancia para la reflexión pedagógica actual: el papel de la globalización, vehiculado por lo sugerente de lo común y de lo diverso en educación matemática y sus desafíos.
Extensive industrialization has led to an increased release of toxic metals into the soil and air. Industrial waste can include mine overburden, bauxite residue, and E waste, and these can serve as a source of valuable recoverable metals. There are relatively simple methods to recycle these wastes, but they require additional chemicals, are expensive, and generate secondary waste that causes environmental pollution. Biohydrometallurgical processing is a cost-effective and ecofriendly alternative where biological processes help conserve dwindling ore resources and extract metals in a nonpolluting way. Microbes can be used in metal extraction from primary ores, waste minerals, and industrial a...
Hepatic surgery represents one of the most challenging fields of surgical practice because it combines the need for surgical excellence with that for deep knowledge and understanding of liver physiology. The various hepatic diseases, whether they are benign or malignant, require surgical expertise in their management, especially given the complex anatomy and physiology of the liver, as well as its critical role in a variety of different biologic functions.This book is a collection of chapters offering the reader distilled knowledge of various worldwide experts in hepatic surgery and hepatic physiology. The surgical management, including complex and demanding surgical procedures, of malignancies such as hepatocellular carcinoma, cholangiocarcinoma, and metastatic disease will be addressed in an effort to present the various therapeutic choices in the surgical armamentarium.Emphasis is given to the molecular aspect of the different mechanisms involved, which offers a glimpse into the future, given the ever-increasing need for precision medicine and surgery, leading to a patient-targeted approach.
How and to what degree are women worldwide gaining and using power? This book offers the first genuinely comparative assessment of this key question by exploring the conditions, actions, and accomplishments of women in Latin America and Asia. Encompassing 60 percent of the world's population and experiencing far-reaching transformations, these two regions offer a vital window into our understanding of the experiences of women globally. Revealing both basic similarities and fundamental differences, this volume offers thoughtful insights about the changing conditions of women, on the one hand, and, on the other, about patterns of social change throughout Asia and Latin America.
