This book provides a clear introduction to this important area of statistics. The author provides a wide of coverage of different kinds of multilevel models, and how to interpret different statistical methodologies and algorithms applied to such models. This 4th edition reflects the growth and interest in this area and is updated to include new chapters on multilevel models with mixed response types, smoothing and multilevel data, models with correlated random effects and modeling with variance.

A personal, journalistic ethnography of the modern American working class, based on the travels and interactions of the author through the American heartland. " Second Class is the most important book you will read all year. A political realignment is coming, and it's my hope that the end result will work in favor of our all-too-neglected American working class. When that realignment comes, Batya and her book will help lead the way." --Greg Lukianoff, CEO of the Foundation for Individual Rights in Education, and co-author of The Coddling of the American Mind Who is the American working class? Do they still have a fair shot at the American Dream? What do they think about their chances to secure the hallmarks of a middle-class life? While writing this book, Batya Ungar-Sargon visited states across the nation to speak with members of the American working class who are fighting tooth and nail to survive. In Second Class , working-class Americans of all races, political orientations, and occupations share their stories--cleaning ladies, health care aides, cops, truck drivers, fast food workers, electricians, and more. In their own words, these working-class Americans explain the struggles and triumphs of their increasingly precarious lives--as well as what policies they think would improve them. Second Class combines deep reporting with a look at the data and expert opinions on America's emergent class divide, in which the most basic elements of a secure and stable life are increasingly out of reach for those without a college education. America has broken its contract with its laboring class. So, how do we get back to the American Dream? How do we once again become the land of opportunity, the promised land, where hard work and commitment to family are enough to protect you from poverty? It's not that hard actually. All it would take, as this book illustrates, is for those in power to once again respect the dignity of work--and the American worker.

Louis Guttman’s pioneering work on scaling theory is cited in Science (1971) as one of 62 major advances in the social sciences in this century, together with those of Freud, Pavlov, Weber, Keynes and others. Scaling theory led Guttman to develop his non-metric methods for data analysis and facet theory, his crowning contribution. Drawing on a large number of periodicals, books and unpublished papers, this volume offers a representative overview of Guttman’s work and demonstrates its utility for cumulative theory-development in sociology, psychology, education, statistics and other disciplines. The basis of facet-theory, and its applications in fields such as social attitudes and intelligence testing, are presented first-hand. Surprising as it may sound, Guttman’s main interest was in theory rather than method. In fact, he saw the two as inseparable, arguing that 'the form of data analysis is part of the hypothesis'.

This book is the first to directly address the question of how to bridge what has been termed the ""great divide"" between the approaches of systems developers and those of social scientists to computer supported cooperative work--a question that has been vigorously debated in the systems development literature. Traditionally, developers have been trained in formal methods and oriented to engineering and formal theoretical problems; many social scientists in the CSCW field come from humanistic traditions in which results are reported in a narrative mode. In spite of their differences in style,

Ithiel de Sola Pool was a distinguished scholar of the political process, and one of the most original thinkers in the development of an integrated social science. This volume focuses upon his contributions to the development of research methods that deepen our understanding of human behaviour. The book is divided into five parts treating the analysis of communications, computer simulation, forecasting, network theory, and the social sciences in political contexts. The first part considers the problems and possibilities of analysis raised by the unprecedented quantity of data made available by widespread and improved communications technology; what should be counted and how should inferences be made. Part two explores computer simulation in the study of presidential election patterns and how it can provide in-depth analyses of crisis situations in history. Part three focuses on strategies for predicting the future of international politics and methods to forecast the impacts of new communications technologies, while part four offers a rigorous analysis of domestic and global contact networks and the so-called "small world" phenomenon. Part five is concerned with external challenges to the use of social science to create more humane politics, including the question of value neutrality, ideology, "deconstructive" critical theory, and threats by government to the health of universities. In a concluding essay Lloyd Etheredge draws upon Pool's work to discuss several new ways in which the methods treated in this volume can be applied to contemporary social change.
