Diffusion Of Innovations In Brazil Nigeria And India

Since the first edition of this landmark book was published in 1962, Everett Rogers's name has become "virtually synonymous with the study of diffusion of innovations," according to Choice. The second and third editions of Diffusion of Innovations became the standard textbook and reference on diffusion studies. Now, in the fourth edition, Rogers presents the culmination of more than thirty years of research that will set a new standard for analysis and inquiry. The fourth edition is (1) a revision of the theoretical framework and the research evidence supporting this model of diffusion, and (2) a new intellectual venture, in that new concepts and new theoretical viewpoints are introduced. This edition differs from its predecessors in that it takes a much more critical stance in its review and synthesis of 5,000 diffusion publications. During the past thirty years or so, diffusion research has grown to be widely recognized, applied and admired, but it has also been subjected to both constructive and destructive criticism. This criticism is due in large part to the stereotyped and limited ways in which many diffusion scholars have defined the scope and method of their field of study. Rogers analyzes the limitations of previous diffusion studies, showing, for example, that the convergence model, by which participants create and share information to reach a mutual understanding, more accurately describes diffusion in most cases than the linear model. Rogers provides an entirely new set of case examples, from the Balinese Water Temple to Nintendo videogames, that beautifully illustrate his expansive research, as well as a completely revised bibliography covering all relevant diffusion scholarship in the past decade. Most important, he discusses recent research and current topics, including social marketing, forecasting the rate of adoption, technology transfer, and more. This all-inclusive work will be essential reading for scholars and students in the fields of communications, marketing, geography, economic development, political science, sociology, and other related fields for generations to come.

The gestation period of this collection has been lengthy even by academic stan dards. Some of our long-suffering contributors prepared their original drafts for a workshop held in Nairobi in 1967, and although they have all up-dated their contributions they are still essentially reporting on research conducted in the late 1960s. However, we feel that their various findings and analyses of the issues they respectively treat have a continuing validity in our comprehension of the problem of rural development. Other contributions reporting on more recent work have been incorporated at different times since, most of them not commissioned especially for this symposium but all adding something to our understanding of the problem. The slow accumulation of material which makes up this fmal collection parallels an evolution in our own collective thinking, if indeed not that of most students of 'development' over the past decade. The progression has not been towards fmal clarification of the complex and changing East African realities, nor towards formulation of an accepted model for their analysis; rather, it has been marked by the questioning of the initial, somewhat simplistic assumptions with which some of us started out and a continuing debate and widening polar ization of views about the significance of that process of government 'pene tration' of the rural areas which is our focus, about the positive or negative value of 'development' policies in East Africa and, indeed, about the appropri ate theoretical approaches to the study of 'development' in general.

Featuring scholarly perspectives from around the globe and drawing on a legacy of television studies, but with an eye toward the future, this authoritative collection examines both the thoroughly global nature of television and the multiple and varied experiences that constitute television in the twenty-first century. Companion chapters include original essays by some of the leading scholars of television studies as well as emerging voices engaging television on six continents, offering readers a truly global range of perspectives. The volume features multidisciplinary analyses that offer models and guides for the study of global television, with approaches focused on the theories, audiences, content, culture, and institutions of television. A wide array of examples and case studies engage the transforming practices, technologies, systems, and texts constituing television around the world today, providing readers with a contemporary and multi-faceted perspective. In this volume, editor Shawn Shimpach has brought together an essential guide to understanding television in the world today, how it works and what it means – perfect for students, scholars, and anyone else interested in television, global media studies, and beyond.
