Universities have been promoting study abroad programmes for a long time to improve intercultural competence. However, the mere exposure to cultural differences while studying abroad does not ensure intercultural competence, unless study abroad students’ reflective processes are explicitly targeted. The article presents the results of a short intervention grounded in the problem-based approach aimed at improving intercultural competence in study abroad students. Students were assigned to three conditions: a video-log condition (in which they have to narrate a critical incident occurred to them), a reflection-induced video-logs (in which they were prompted to reflect on the video-logs produced), and an active control condition. The reflection-induced video-log intervention improved students’ perceived proficiency in Italian and perceived opportunities for cultural reflection, but it did not contribute to improve students’ applicable and conceptual knowledge of intercultural competence.

Mining direct antagonistic communities in signed social networks   总被引:1,自引:1,他引:0  
Social networks provide a wealth of data to study relationship dynamics among people. Most social networks such as Epinions and Facebook allow users to declare trusts or friendships with other users. Some of them also allow users to declare distrusts or negative relationships. When both positive and negative links co-exist in a network, some interesting community structures can be studied. In this work, we mine Direct Antagonistic Communities (DACs) within such signed networks. Each DAC consists of two sub-communities with positive relationships among members of each sub-community, and negative relationships among members of the other sub-community. Identifying direct antagonistic communities is an important step to understand the nature of the formation, dissolution, and evolution of such communities. Knowledge about antagonistic communities allows us to better understand and explain behaviors of users in the communities.  相似文献
