The point-group symmetry is broken by the sample shape of any finite ...

Data Monitoring Committees (DMCs) are responsible for safeguarding the interests of study participants and assuring the integrity and credibility of clinical trials. The independence of DMCs from sponsors and investigators is essential to achieving this mission. Creative approaches are needed to address ongoing and emerging challenges that potentially threaten DMCs' independence and effectiveness. An expert panel of representatives from academia, industry and government sponsors, and regulatory agencies discussed these challenges and proposed best practices and operating principles for effective functioning of contemporary DMCs.

The lifecourse perspective on adult health and on health inequalities in particular, is one of the most important recent developments in epidemiology and public health. This book brings together, in a single volume, the work of one of the most distinguished academics in the field. It is the first to specifically take a lifecourse approach to health inequalities and will be essential reading for academics, students and policy makers with an interest in public health, epidemiology, health promotion and social policy

Child poverty is a central and present part of global life, with hundreds of millions of children around the world enduring tremendous suffering and deprivation of their most basic needs. Despite its long history, research on poverty and development has only relatively recently examined the issue of child poverty as a distinct topic of concern. This book brings together theoretical, methodological and policy-relevant contributions by leading researchers on international child poverty. With a preface from Sir Richard Jolly, Former Assistant Secretary General of the United Nations, it examines how child poverty and well-being are now conceptualized, defined and measured, and presents regional and national level portraits of child poverty around the world, in rich, middle income and poor countries. The book's ultimate objective is to promote and influence policy, action and the research agenda to address one of the world's great ongoing tragedies: child poverty, marginalization and inequality
