“…Certain properties of language may be particularly important indicators of community health—specifically, sentiment (or emotion) 2 and gratitude, given the importance of these to individual and interpersonal processes to social health generally and within software programming communities (Algoe, 2012 ; Dabbish, Stuart, Tsay, & Herbsleb, 2012 ; Emmons & Shelton, 2002 ; França, Sharp, & Da Silva, 2014 ; Steinmacher, Conte, Gerosa, & Redmiles, 2015 ; Yoshimura & Berzins, 2017 ). However, consistent with a dynamical systems approach to language (Gibbs & Van Orden, 2012 ; Hodges & Fowler, 2010 ; Paxton, Dale, & Richardson, 2016 ), these patterns should be sensitive to the specific context in which communication occurs (Mäntylä, Adams, Destefanis, Graziotin, & Ortu, 2016 ; Rączaszek‐Leonardi & Kelso, 2008 ) and the person's own relationship with the community (and, by extension, their enculturation into the community; Thorne, Black, & Sykes, 2009 ; Rączaszek‐Leonardi, 2010 ). Therefore, patterns should vary by the community (Port, 2010 ; Thorne et al., 2009 ) and over time (i.e., as members join and leave; Demjén, 2018 ; Rączaszek‐Leonardi & Kelso, 2008 ).…”
