“…Social media has facilitated large scale science-focused initiatives, notably health campaigns (Koohy and Koohy, 2014) and some environmental projects (Aldred, 2016;Ballard et al, 2017;Plastic Patrol, 2017) highlighting the far-reaching influence social media can have on actions, attitudes, and behaviors (Centola, 2010, Korda andItani, 2013). Despite such potential, and many corporate businesses regarding social media presence as, "top of the agenda" (Kaplan and Haenlein, 2010, p. 59), academic institutions are said to fall behind in their online activity (Peters et al, 2008;Liang et al, 2014;Jarreau and Yammine, 2017;Howell et al, 2019;Koivumäki and Wilkinson, 2020), despite the value it can bring for public engagement (Bernhardt et al, 2011;Wilkinson and Weitkamp, 2016). Engagement is often considered effective if it results in behavioral or attitudinal change, particularly around issues such as climate change, health, and the environment (Lorenzoni et al, 2007;Corner and Randall, 2011) and sites such as Twitter are known to facilitate such interaction outcomes (Simis- Wilkinson et al, 2018).…”
