The present study investigates the influence of audiences' ethnocentrism on their parasocial interaction (PSI) with sitcom characters. A total of 156 American college students participated in the study that involved viewing a British sitcom and its American remake. For audiences with high ethnocentrism, PSI with the male character in the American remake was significantly higher than that with the corresponding character in the British sitcom, whereas for people with low ethnocentrism, PSI with the male character in the British sitcom was significantly higher than that with the corresponding character in the American remake. People with high as well as low ethnocentrism did not exhibit significant PSI difference with the female character in the British sitcom and its American remake. Public Policy Relevance StatementThis study shows that ethnocentrism negatively influences audiences' parasocial interaction with media figures from another culture, but such an influence varies by individual media characters.

The accident rate is high in subway maintenance work, and most of the accidents are caused by human factors, especially the lack of sensitivity to risk perception, the lack of rigorous attitude towards safety and the lack of safe citizenship behavior (SCB). Therefore, it is very important to study the risk perception (RP), safety attitude (SA) and SCB of metro maintenance staff in order to reduce the accident rate. In order to reduce human errors and accidents, this study analyzed the influence of metro maintenance staff’s RP on their SCB and the mediating role of SA. Based on previous studies, this paper uses the risk perception scale, safety attitude scale and safety citizenship behavior scale as research tools. A survey was administered at the Subway Company, and altogether 268 valid questionnaires were used, and the data were analyzed by SPSS19.0 (IBM, Armonk, NY, USA) and AMOS 24.0 (IBM, Armonk, New York, NY, USA). The result reveals that SA plays a complete mediating role between metro maintenance staff’s RP and their SCB; and SA has a positive influence on SCB; RP has a positive influence on SA; and SA positively predicts SCB.
