Book excerpt: Getting an innovation adopted is difficult; a common problem is increasing the rate of its diffusion. Diffusion is the communication of an innovation through certain channels over time among members of a social system. It is a communication whose messages are concerned with new ideas; it is a process where participants create and share information to achieve a mutual understanding. Initial chapters of the book discuss the history of diffusion research, some major criticisms of diffusion research, and the meta-research procedures used in the book. This text is the third edition of this well-respected work. The first edition was published in 1962, and the fifth edition in 2003. The book's theoretical framework relies on the concepts of information and uncertainty. Uncertainty is the degree to which alternatives are perceived with respect to an event and the relative probabilities of these alternatives; uncertainty implies a lack of predictability and motivates an individual to seek information. A technological innovation embodies information, thus reducing uncertainty. Information affects uncertainty in a situation where a choice exists among alternatives; information about a technological innovation can be software information or innovation-evaluation information. An innovation is an idea, practice, or object that is perceived as new by an individual or an other unit of adoption; innovation presents an individual or organization with a new alternative(s) or new means of solving problems. Whether new alternatives are superior is not precisely known by problem solvers. Thus people seek new information. Information about new ideas is exchanged through a process of convergence involving interpersonal networks. Thus, diffusion of innovations is a social process that communicates perceived information about a new idea; it produces an alteration in the structure and function of a social system, producing social consequences. Diffusion has four elements: (1) an innovation that is perceived as new, (2) communication channels, (3) time, and (4) a social system (members jointly solving to accomplish a common goal). Diffusion systems can be centralized or decentralized. The innovation-development process has five steps passing from recognition of a need, through R&D, commercialization, diffusions and adoption, to consequences. Time enters the diffusion process in three ways: (1) innovation-decision process, (2) innovativeness, and (3) rate of the innovation's adoption. The innovation-decision process is an information-seeking and information-processing activity that motivates an individual to reduce uncertainty about the (dis)advantages of the innovation. There are five steps in the process: (1) knowledge for an adoption/rejection/implementation decision; (2) persuasion to form an attitude, (3) decision, (4) implementation, and (5) confirmation (reinforcement or rejection). Innovations can also be re-invented (changed or modified) by the user. The innovation-decision period is the time required to pass through the innovation-decision process. Rates of adoption of an innovation depend on (and can be predicted by) how its characteristics are perceived in terms of relative advantage, compatibility, complexity, trialability, and observability. The diffusion effect is the increasing, cumulative pressure from interpersonal networks to adopt (or reject) an innovation. Overadoption is an innovation's adoption when experts suggest its rejection. Diffusion networks convey innovation-evaluation information to decrease uncertainty about an idea's use. The heart of the diffusion process is the modeling and imitation by potential adopters of their network partners who have adopted already. Change agents influence innovation decisions in a direction deemed desirable. Opinion leadership is the degree individuals influence others' attitudes.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Now in its fifth edition, Diffusion of Innovations is a classic work on the spread of new ideas. In this renowned book, Everett M. Rogers, professor and chair of the Department of Communication & Journalism at the University of New Mexico, explains how new ideas spread via communication channels over time. Such innovations are initially perceived as uncertain and even risky. To overcome this uncertainty, most people seek out others like themselves who have already adopted the new idea. Thus the diffusion process consists of a few individuals who first adopt an innovation, then spread the word among their circle of acquaintances—a process which typically takes months or years. But there are exceptions: use of the Internet in the 1990s, for example, may have spread more rapidly than any other innovation in the history of humankind. Furthermore, the Internet is changing the very nature of diffusion by decreasing the importance of physical distance between people. The fifth edition addresses the spread of the Internet, and how it has transformed the way human beings communicate and adopt new ideas.

Download or read book Innovation and Technological Diffusion written by Harry Kitsikopoulos and published by Routledge. This book was released on 2015-10-23 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with two key aspects of the history of steam engines, a cornerstone of the Industrial Revolution, specifically the road that led to its discovery and the process of diffusion of the early steam engines. The first part of the volume outlines the technological and scientific developments which took place between the 16th and 18th centuries, proving critical for the invention of this strategic technology. The most important question addressed is why did England come up with this innovation first as opposed to other countries (e.g., France, Italy), which were more advanced in terms of knowledge pertinent to it. The second part of the volume traces the process of diffusion of the early steam engines, the Newcomen model, through to 1773, the year prior to the first commercial application of the second generation of steam engines (the Watt model). The process of diffusion is quantified on the basis of a novel method before proceeding with a discussion of the main determinants of this process. Kitsikopoulos pulls together a large amount of relevant evidence found in primary sources and more technically oriented literature which is often ignored by economic historians. This book will be of interest to economic historians and historians of technology.

Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1973, this book synthesizes the mass of material into an introduction to the study of spatial systems. Geographic literature of the time stressed the influence of the distance between places on both location decision-making and movement patterns, arguing that the spatial system is an ordered set of interacting locations. This system is created by human decisions, influenced by the distance factor, and the system’s morphology constrains further activities, including those which would alter it. Spatial Structures outlines the development of such systems, their present organization, and the ways in which they are changing. These themes are dealt with in three main chapters which focus on different spatial scales – the individual city, the nation state and the international system, within a simple classification of spatially organized activities.

Available in PDF, EPUB and Kindle. Book excerpt: In the last fifty years the investigation of maritime archaeological sites in the sea, in the coastal zone and in their interconnecting locales, has emerged as one of archaeology's most dynamic and fast developing fields. No longer a niche interest, maritime archaeology is recognised as having central relevance in the integrated study of the human past. Within maritime archaeology the study of watercraft has been understandably prominent and yet their potential is far from exhausted. In this book Jon Adams evaluates key episodes of technical change in the ways that ships were conceived, designed, built, used and disposed of. As technological puzzles they have long confounded explanation but when viewed in the context of the societies in which they were created, mysteries begin to dissolve. Shipbuilding is social practice and as one of the most complex artefacts made, changes in their technology provide a lens through which to view the ideologies, strategies and agency of social change. Adams argues that the harnessing of shipbuilding was one of the ways in which medieval society became modern and, while the primary case studies are historical, he also demonstrates that the relationships between ships and society have key implications for our understanding of prehistory in which seafaring and communication had similarly profound effects on the tide of human affairs.

Download or read book The Evolution of Techniques written by Mathieu Charbonneau and published by MIT Press. This book was released on 2024-03-19 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel, interdisciplinary exploration of the relative contributions of rigidity and flexibility in the adoption, maintenance, and evolution of technical traditions. Techniques can either be used in rigid, stereotypical ways or in flexibly adaptive ways, or in some combination of the two. The Evolution of Techniques, edited by Mathieu Charbonneau, addresses the impacts of both flexibility and rigidity on how techniques are used, transformed, and reconstructed, at varying social and temporal scales. The multidisciplinary contributors demonstrate the important role of the varied learning contexts and social configurations involved in the transmission, use, and evolution of techniques. They explore the diversity of cognitive, behavioral, sociocultural, and ecological mechanisms that promote and constrain technical flexibility and rigidity, proposing a deeper picture of the enablers of, and obstacles to, technical transmission and change. In line with the extended evolutionary synthesis, the book proposes a more inclusive and materially grounded conception of technical evolution in terms of promiscuous, dynamic, and multidirectional causal processes. Offering new evidence and novel theoretical perspectives, the contributors deploy a diversity of methods, including ethnographies, field and laboratory experiments, cladistics and phylogenetic tree building, historiography, and philosophical analysis. Examples of the wide range of topics covered include field experiments with potters from five cultures, stability and change in Paleolithic toolmaking, why children lack flexibility when making tools, and cultural techniques in nonhuman animals. The volume’s three thematic sections are: · Timescales of technical rigidity and flexibility · Rigid copying to flexible reconstruction · Exogenous factors of technical rigidity and flexibility The volume closes with a discussion by philosopher Kim Sterelny.

Download or read book The Vital Spark written by John Armstrong and published by Liverpool University Press. This book was released on 2017-10-18 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book collects seventeen previously published essays by John Armstrong concerning the British coastal trade. Armstrong is a leading maritime historian and the essays provided here offer a thorough exploration of the British coastal trade, his specialisation, during the period of industrialisation and technological development that would lead to modern shipping. The purpose is to demonstrate the whether or not the coastal trade was the main carrier of internal trade and a pioneer of the technical developments that modernised the shipping industry. Each essay makes an original contribution to the field and covers a broad range of topics, including the fluctuating importance of the coastal trade and size of the coastal fleet over time; the relationship between coastal shipping, canals, and railways; a comparison between the coastal liner and coastal tramp trade; the significance of the river Thames in enabling trade; coastal trade economics; maritime freight rates; the early twentieth century shipping depression; competition between coastal liner companies; and a detailed study of the role of the government in coastal shipping. The book also contains case studies of the London coal trade; coastal trade through the River Dee port; and the Liverpool-Hull trade route. It contains a foreword, introduction, and bibliography of Armstrong’s writings. There is no overall conclusion, except the assertion that coastal shipping plays a tremendous role in British maritime history, and a call for further research into the field.
