Sample Size Determination and Power

This book provides statisticians and researchers with the statistical tools – equations, formulae and numerical tables – to design and plan clinical studies and carry out accurate, reliable and reproducible analysis of the data so obtained. There is no way around this as incorrect procedure in clinical studies means that the researcher's paper will not be accepted by a peer-reviewed journal. Planning and analysing clinical studies is a very complicated business and this book provides indispensible factual information.

This volume presents a systematic discussion of the leading theoretical approaches to social stratification. It is both an accessible overview and a distinctive contribution to the analysis of class, status and power. John Scott argues that Max Weber's conceptual framework – reconstructed and enlarged – provides the basis for integrating what have been considered up to now as divergent approaches to stratification studies. Marxist theories of class and economic division, normative functionalist theories of status and cultural division, and elitist theories of command and authoritarian division all find their place in the proposed framework. Each theoretical approach is illustrated through empirical investigations undertaken by writers associated with them. Recent work by Dahrendorf, Wright and Goldthorpe is also examined, and it is shown how their arguments contribute to a theoretical synthesis in the analysis of stratification. Stratification and Power will be much appreciated by students and academics alike in the social sciences. The clarity of its style and the significance of its contribution have made it a leading text in its field.

Performativity has emerged as a critical new idea across the humanities and social sciences, from literary and cultural studies to the study of gender and the philosophy of action. In this volume, Jeffrey Alexander demonstrates how performance can reorient our study of politics and society. Alexander develops a cultural pragmatics that shifts cultural sociology from texts to gestural meanings. Positioning social performance between ritual and strategy, he lays out the elements of social performance – from scripts to mise-en-sc?ne, from critical mediation to audience reception – and systematically describes their tense interrelation. This is followed by a series of empirically oriented studies that demonstrate how cultural pragmatics transforms our approach to power. Alexander brings his new theory of social performance to bear on case studies that range from political to cultural power: Barack Obama's electoral campaign, American failure in the Iraqi war, the triumph of the Civil Rights Movement, terrorist violence on September 11th, public intellectuals, material icons, and social science itself. This path-breaking work by one of the world's leading social theorists will command a wide interdisciplinary readership.

In this important new book, the leading philosopher Fran?ois Laruelle examines the role of intellectuals in our societies today, specifically with regards to criminal justice. He argues that, rather than concerning themselves with abstract philosophical notions like justice, truth and violence, intellectuals should focus on the human victims. Drawing on his influential theory of ‘non-philosophy’, he shows how we can submit the theorizing of intellectuals to the scrutiny of the everyday suffering of the victims of crime. In the course of a wide-ranging discussion with Philippe Petit, Laruelle suspends the presumed authority of intellectuals by challenging the image of the ‘dominant intellectual’ exemplified by philosophers such as Sartre, Foucault, Lyotard and Debray. In place of domination, he puts forward instead a theory of ‘determination’: the determined intellectual is one whose character is conditioned by his relationship to the victim, rather than one who attempts to dominate the victim’s experience through a process of theorizing. While philosophy consistently takes the voice away from victims of suffering, non-philosophy is able to construct a theory of violence and crime that gives voice to the victim. This highly original book will be essential reading for all those interested in contemporary French philosophy and all those concerned with justice in the modern world.

It is now almost twenty years since liberalisation and the introduction of competition was proposed for electricity utilities. Some form of restructuring has been widely adopted around the world to suit local objectives. The industry now faces new challenges associated with global warming, rising prices and escalating energy demand from developing countries like China and India. The industry will have to cope with; managing emissions; managing variable energy sources like wind, dev eloping clean coal technology; accommodating distributed generation and new nuclear stations and managing the impact of these developments on the distribution and transmission networks. It is now necessary to consider how the various market structures that were adopted have performed and how they will address some of these new issues and what further changes might be necessary. This volume presents an all-inclusive analysis of the electricity market structures that have been adopted around the world and how they are performing. It provides an up-to-date analysis of the cost of competing technologies, the operation of energy and ancillary service markets and the impact of renewable sources and emission restrictions. It takes a forward look at likely future developments necessary to cope with the new emerging issues. Part One introduces industry infrastructure, analysing state utilities, the motives behind liberalisation and the resulting structures. Part Two considers generation costs, including renewable generation costs, and investigates the cost of restricting emissions as well as transmission and distribution costs. Part Three discusses market operation, describing how costs affect the organisation of power generation. It covers trading arrangements, ancillary services, international trading and investment. Part Four looks to future markets and technological developments that will shape the industry through the next twenty years. This includes the appraisal of investment opportunities for global power companies and implications for market performance. Written by an internationally renowned consultant engineer, this book is full of expert insight and balances fundamental methodology and academic theory with practical information and diverse worked examples. This is an excellent reference on the topic for power system engineers, regulators, banks, investors, and government energy agencies. With its many worked examples, it is also a brilliant tutorial accessible for postgraduates and senior undergraduates in electrical and power engineering.
