Chapter 5112of boxes of strawberries on a conveyor is accompanied with text about the food industry that uses nanotechnology to improve foods’ nutrition and overall quality. The health-concern storyline is about health concerns, risks, or threats posed by nanotechnology in food. The tweets’ textual tone is always negative. Some tweets with this storyline visualize worrisome or alarming charts, lists, or banners and provide more information in the tweet’s text. Other tweets show foods or people interacting with foods in what seems to be an ordinary way of interacting. When one reads these tweets’ text, it becomes clear that they express health concerns related to the food, or the interaction, that appears in the visualisation. For example, a visualisation of a baby drinking from a bottle is accompanied with text about hazardous nano-ingredients in baby formula. More image–text storylines revealed in tweets are elaborated on in Annex C, Table C1.5.4.2 Circulating across platformsOf the visualisations belonging to the most retweeted tweets about nanotechnology in food, 14 visualisations circulated frequently on the open Web also (Table 5.1). The visualisations depict various objects, mainly foods, plants, people or body parts, and landscapes.5.4.3 Circulating across topical contextsThe results show that visualisations that circulated on Twitter in the nanotechnology-in-food context circulated on the open Web in various topical contexts. Among 667 URLs containing these visualisations, 39 discussed nanotechnology in food and their main topic is mostly food related (Table 5.1). Among the rest of the URLs, some discussed topics that can be seen as related to nanotechnology in food, such as genetically modified organism (GMO) (Handford et al., 2014; Henchion et al., 2019; Schwarz-Plaschg, 2018). Other URLs discussed topics related to food, for example food production, food vacuum packaging, and the agri-food sector. The remaining URLs discussed topics that are not related in any way to food or nanotechnology in food, for example makeup/beauty/cosmetics or Japan. Visualisations that did circulate on both Twitter and the open Web in the nanotechnology-in-food context (Table 5.1, lines 3, 4, 5, 7, 8, 9, 12) were visualisations of foods, farmers, and landscapes, and visualisations that seem to illustrate a problem (Table 5.1, lines 5 and 12). More observations about the change in the tone of the visualisations’ accompanying text, when circulating across topical contexts, are below. Efrat.indd 112 19-09-2023 09:47
