The goal for any social scientist doing a survey is to develop a rating on some attitude, value or opinion - a summated rating scale. Aimed at helping researchers construct more effective scales, Spector shows how to determine the number of items necessary, the appropriate amount of response categories and the most productive wording of items, how to sort good items from bad (including item-remainder coefficients and Cronbach′s alpha) and how to validate a scale, including dimensional validity from factor analysis. Written in a user-friendly manner, the book concludes with a step-by-step account of how to develop a summated rating scale based on classical test theory.

How do political institutions help promote prosperity in some countries and poverty in others? What can be done to encourage leaders to govern not for patronage but for economic growth? In this book, such distinguished political economists as Douglass North, Robert Barro, and Stephen Haber answer these questions, providing a solution to one of the most important policy puzzles of the new century: how to govern for prosperity. The authors begin from a premise that political leaders are self-interested politicians rather than benign agents of the people they lead. When leaders depend on only a few backers to stay in power, they dole out privileges to those people, thereby dissipating their country's total resources and national growth potential. On the other hand, leaders who need large coalitions to stay in office implement policies that generally foster growth and political competition over ideas. The result is that those who promote policies that lead to stagnation tend to stay in office for a long time, and those who produce prosperity tend to lose their jobs. Analyzing countries in North and South America and Asia, the authors discuss the range of political regimes that permit or even encourage leaders to rule by mismanaging their nation's resources. And they show that nations must forge institutions that allow all social groups to participate in and benefit from the economy as well as force political leaders to be responsible for policy outcomes.

Realistic Evaluation

Category: Social Science
Page: 256

Realistic Evaluation shows how program evaluation needs to be, and can be bettered. It presents a profound yet highly readable critique of current evaluation practice, and goes on to introduce a `manifesto' and `handbook' for a fresh approach. The main body of this book is devoted to the articulation of a new evaluation paradigm, which promises greater validity and utility from the findings of evaluation studies. The authors call this new approach `realistic evaluation'. The name reflects the paradigm's foundation in scientific realist philosophy, its commitment to the idea that programmes deal with real problems rather than mere social constructions, and its primary intention, which is to inform realistic developments in policy making that benefit programme participants and the public. Ray Pawson and Nicholas Tilley argue with passion that scientific evaluation requires a careful blend of theory and method, quality and quantity, ambition and realism. The book offers a complete blueprint for evaluation activities, running from design to data collection and analysis to the cumulation of findings across programmes and onto the realization of research into policy. The argument is developed using practical examples throughout and is grounded in the major fields of programme evaluation. This book will be essential reading for all those involved in the evaluation process especially those researchers, students and practitioners in the core disciplines of sociology, social policy, criminology, health and education. `This book is a must for those engaged in the field, providing a fully illustrated text on evaluation with numerous examples from the criminal justice system. Unusually, it offers something for the academic, practitioner and student alike. I found Pawson and Tilley's latest work on evaluation an enjoyable and informative read. For myself their "realistic evaluation" clarified and formalised a jumbled set of ideas I had already been developing. Although not everyone will agree with the methodology proposed by the authors, this book is a valuable read as it will cause most of us at least to review our methodological stance' - International Journal of Police Science and Management `This is an engaging book with a strong sense of voice and communicative task. The voice is sometimes strident, but always clear. Its communicative qualities are evident equally in its structure: lots of signposting for the reader within and across chapters' - Language Teaching Research `This provocative, elegant and highly insightful book focuses on the effective incorporation of actual practice into the formulation of evaluation methodology. What a pleasure to read sentences like: "The research act involves "learning" a stakeholder's theories, formalizing them, and "teaching" them back to that informant who is then in a position to comment upon, clarify and further refine the key ideas". Pawson and Tilley have given us a wise, witty and persuasive account of how real practitioner experience might be encouraged to intrude on (and modify) researchers' concepts about program processes and outcomes. This holds important promise for achieving something that is devoutly to be wished: closer interaction among at least some researchers and some policy makers' - Eleanor Chelimsky, Past-President of the American Evaluation Association `This is a sustained methodological argument by two wordly-wise social scientists. Unashamedly intellectual, theoretically ambitious yet with a clear but bounded conception of evaluation. It is articulate, occasionally eloquent and always iconoclastic, whilst eschewing "paradigm wars". The Pawson and Tilley "realist" call to arms threatens to take no prisoners among experimentalists, constructivists or pluralists. It is the kind of book that clarifies your thoughts, even when you disagree with everything they say' - Elliot Stern, The Tavistock Institute

`This clearly written and user-friendly book is ideal for students or researchers who wish to get a basic, but solid grasp of a topic and see how it fits with other topics. By following the links a student can easily and efficiently build up a clear conceptual map of social research' - Malcolm Williams, Reader in Sociology, Cardiff University `This is a really useful book, written in an accessible manner for students beginning their study of social research methods. It is helpful both as an introductory text and as a reference guide for more advanced students. Most of the key topics in methods and methodology are covered and it will be suitable as a recommended text on a wide variety of courses' - Clive Seale, Brunel University At last, an authoritative, crystal-clear introduction to research methods which really takes account of the needs of students for accessible, focused information to help with undergraduate essays and exams. The key concepts discussed here are based on a review of teaching syllabi and the authors' experience of many years of teaching. Topics range over qualitative and quantitative approaches and combine practical considerations with philosophical issues. They include several new topics, like internet and phone polling, internet searches, and visual methods. Each section is free-standing, can be tackled in order, but with links to other sections to enable students to cross-reference and build up a wider understanding of central research methods. To facilitate comprehension and aid study, each section begins with a definition. It is followed by a summary of key points with key words and guides to further reading and up-to-date examples. The book is a major addition to undergraduate reading lists. It is reliable, allows for easy transference to essays and exams and easy to use, and exceptionally clearly written for student consumption. The book answers the needs of all those who find research methods daunting, and for those who have dreamt of an ideal introduction to the subject.
