Chapter 128Chapter 3 focusses mainly on the second aspect of meaning-making – narrative – and examines the role of visualisations in shaping the discourses around hydraulic fracturing for shale gas extraction. It illustrates how visualisations can contribute to discourse formation by networking or isolating content and actors. The chapter introduces the concept of visual discourse coalition and uses examples from the Netherlands, New York State and South Africa to illustrate four ways in which visualisations can influence the dynamics within and between discourse coalitions.Chapter 4 focusses mainly on the second aspect of meaning-making and analyses the use of visualisations in the communication of information about processed food, comparing textual and visual framing. The chapter introduces the notion of an online sentiment coalition and uses Google queries to construct a dataset, which is analysed to uncover the positive, negative and balanced sentiment coalitions and the text and visualisations they use. The results highlight the different meanings of processed food in society and the contribution of visual analysis to understanding these meanings.Chapter 5 focusses mainly on the third aspect of meaning-making – circulation – and examines visualisations of nanotechnology in food and food packaging on Twitter and the open Web. The chapter studies circulating visualisations withinplatform, across Twitter and the open Web and in different topical contexts. It also provides an in-depth analysis of storylines about nanotechnology-in-food on Twitter and the open Web. The chapter takes a multimodal approach and, using Twitter API and Google reverse image search, shows the dynamic meaning of visualisations by analysing textual tone, image–text storyline and how these change over time and during visualisations’ circulation.Chapter 6 summarises the main findings revealed in the empirical chapters and answers the thesis’s sub-questions and general question. On the basis of these answers, the chapter draws conclusions and includes a discussion of them. It also reflects on methods, suggests directions for future research and offers advice to those who study policy controversies and those who visualise the issues at their hearts.Efrat.indd 28 19-09-2023 09:47
