To what extent does the reporting behavior of the media regarding a celebrity suicide influence subsequent suicides in South Korea?

This study investigated the nature of media coverage of a national entertainer's suicide and its impact on subsequent suicides. After the celebrity suicide, the number of suicide-related articles reported surged around 80 times in the week after the suicide compared with the week prior. Many articles (37.1%) violated several critical items on the World Health Organization suicide reporting guidelines, like containing a detailed suicide method. Most gender and age subgroups were at significantly higher risk of suicide during the 4 weeks after the celebrity suicide. Results imply that massive and noncompliant media coverage of a celebrity suicide can cause a large-scale copycat effect.

How consumers evaluate eWOM (electronic word-of-mouth) messages.

This experiment explored how consumers evaluate electronic word-of-mouth (eWOM) messages about products. Each participant was exposed a 10-message set in a single board. Five groups were manipulated in terms of their ratios of positive and negative messages. The result showed significant differences across various sets of eWOM messages. Although more positive sets showed higher scores in many cases, this was not true in all situations, especially for the case of credibility. Involvement and prior knowledge partially moderated the relationship between the ratio of messages and the eWOM effect. The credibility of Web sites and eWOM messages can be damaged in the long run if all of the eWOM messages are positive.
