"The book's structure alternates between context (including theory and policy) and cases. Each case is discussed in relation to a particular aspect of social innovation: Chapter 2 discusses three projects, all of which tackle environmental change and demonstrate the ways in which social innovation media works across local and networked cultures. Chapter 4 delves into the human rights organization, WITNESS, and discusses the concept of systems change, where making a difference requires coordinating interconnected elements within the socio-technical system. Chapter 6 looks at two youth media organizations to unpack how innovation and development can sometimes demand different approaches and organizational structures. Chapter 8 discusses an Indigenous leadership programme that uses the format of a catwalk event, showing how social networks and entertainment can be used to propel novel responses to disadvantage. Chapters 3, 5, 7 and 9 provide conceptual tools for navigating the social innovation media field: Chapter 3 discusses the origin and meaning of social innovation, including the growin interest in the contribution of digital media and technologies. Chapter 5 maps social innovation media onto evolving cultural policy discourses. We also attempt to measure the size of the social innovation media field in one country (Australia) to illustrate the difficulties in defining the field through data. Chapter 7 examines the social innovation media workforce and the motivations that underpin it. Through a qualitative analysis of youth media programmes in the United States and Australia, we show how idealistic and pragmatic motivations, as well as social interactions and cooperative mechanisms propel these media projects. Chapter 9 covers social impact evaluation. We look at the importance of context specific approaches (across qualitative and quantitative methods), the role of evaluation as a learning and feedback mechanism for organizations, as well as issues of scale and replicability. The final chapter brings together the various themes of the book and discusses the key challenges for policy and research. We have also provided a short summary of the pragmatic insights we derived from our research, written specifically for social innovation practitioners." (Pages 12-13)
