“…The action research and analysing texts techniques were applied respectively on 4% and 3% of the studies. For instance, action research was applied by (Cloutier, Renard, Arcand, & Laviolette, 2016) to investigate the collaboration for innovation among stakeholders of a cider Route in Canada, and analysing texts was applied by Payne & Hurt (2015) to explore what heritage themes the Route 66 sites convey to tourists. Finally, other techniques correspond to 8% of the total, for instance, big data (Tikunov, Belozerov, Panin, & Antipov, 2018), biographical method (Teye & Timothy, 2004), and the Delphi technique (De La Torre, Caridad Y Ocerín, Fuentes, & Hidalgo, 2014), among others.…”
