Chapter 51105.4.1 Circulating within a platform (Twitter)Tone The results of the tweets’ tone analysis show that, in the tweets that circulated the most and contained images, tweets with a positive tone are the largest group. Slightly fewer tweets have text with a negative tone. Tweets with a neutral tone are the smallest group (Figure 5.2).0 5 10 15 20 25 30 35 40 45NegativeNeutralPositiveNumber of tweetsFigure 5.2. Overview of the tone of the text of the most retweeted tweets containing imagesStorylineThe results reveal nine image–text storylines in the visualisations and their accompanying text (the text of the tweet in which they were used) (Figure 5.3).The food-security-and-food-sustainability storyline has the highest number of tweets and is about nanotechnology that advances these conditions or qualities. The tweets’ textual tone is always positive. Three tweets with this storyline are also part of the health-benefit storyline, and two tweets are part of the scientificdevelopment storyline. Illustrative tweets of food security and food sustainability contain visualisations of scientific innovations with text describing the innovation and how it benefits society. For example, a visualisation of a cucumber being peeled is accompanied with text explaining that cellulose nano-crystals from cucumber peels are used to create environmentally friendly food-packaging material.Efrat.indd 110 19-09-2023 09:47
