The results of a survey administered on the case of the candlelight rallies on the U.S. beef imports in South Korea in 2008 demonstrated that involvement, problem recognition, and constraint recognition predicted communication behaviors as well as various issue-related online and offline behaviors. In addition, anger was found to be a significant driving force for publics to perform the behaviors. The segmented publics showed significantly different levels of anger, information processing and seeking, online behaviors, and participation in the candlelight rallies展开更多
