“…To trace how problem uncertainty was constructed over time in each province the study draws on thematic and content analysis of over 400 news articles. Media analysis is a useful technique in tracing changes in problem uncertainty over time because of the ability to isolate particular frames regarding fracking, as well as the actor, source, and date of each claim (Blair, Weible, Heikkila, & McCormack, 2015; Bronson, Dobson, & O'Doherty, 2019; Lodge & Matus, 2014; Olive, 2016; Olive & Delshad, 2017). The author and a research assistant developed a database of articles gathered using keyword searches of terms “hydraulic fracturing,” “fracking,” “unconventional gas,” or “shale gas.” The search yielded 220 articles from the Chronicle Herald in Nova Scotia and 218 articles from the Vancouver Sun , regional newspapers with the highest circulation in each province.…”
