PapersAn analysis of blog readers’ behavior according to reader-perceived bloggers’ types during the 2007 Upper-House election campaign in JapanIn refereedAcademic JournalSingle-AuthorOGASAHARA, Morihiro;;2010/7～Nowadays, countless Internet users are reading blogs and various types of actors (consumer, celebrity, company, etc) are writing blogs. Blogs have become one of the most important and abundant information sources for Internet users. Despite the importance of research on blogs, most research focuses on either blogs themselves or bloggers, rarely on blog readers. Additionally, research on blog readers have not considered the variety of bloggers enough. This paper proposes a new classification of blogs perceived by blog readers: "well-known people's blogs", "acquaintances' blogs", "others' blogs", and "organizations' blogs". An internet questionnaire survey of blog readers (N = 300) was conducted and variables related to blogs classified by categories above were examined. People who read blogs during the 2007 Upper-House election campaign in Japan completed online surveys exploring what type of blogs they read and how they evaluated those blogs. Readers of acquaintances’ blogs’ accessed blogs most frequently and read political information as personal affairs. Readers of well-known people’s blogs’ and organizations’ blogs read political information as if it was news. Acquaintances' blogs were regarded highly on familiarity. Well-known people's blogs were regarded highly according to the measures of popularity. Others' blogs received low evaluations on all measures. Organizations' blogs were highly regarded for credibility. Finally, organizations’ blogs readers tended to talk about political information in blog entries with friends and acquaintances. This analysis suggests that the classification of blogs proposed by this research can be useful for understanding the varieties of blog readers’ behavior and recommendations for further theoretical development are discussed.

PapersQuantitative analysis on the model for media credibility formation on the InternetIn refereedAcademic JournalSingle-AuthorOGASAHARA, Morihiro;;2008/7～This paper proposes a new model for media credibility formation on the Internet through an analysis of quantitative research data. There are two main findings. First, there are various models depending on the patterns of Internet use. In the case of Internet users who only access websites operated by organizations, the longer they use the Internet per week, the higher their media credibility becomes. Thus, the model is similar to that of newspapers. On the other hand, Internet users who access websites operated by individuals, there is no correlation between the length of media usage time and the media credibility. Second, "general media trust", a psychological aptitude that accounts for the level of credibility an individual has for any information source irrespective of media forms, has a great influence on credibility formation.

PapersLinks between real and virtual networks: a comparative study of online communities in Japan and KoreaIn refereedAcademic JournalCo-authorISHII, Kenichi;OGASAHARA, Morihiro;CYBERPSYCHOLOGY & BEHAVIORVolume 10, Number 2, 252-2572007/4～Mary Ann Liebert, IncThe present study explores how online communities affect real-world personal relations based on a cross-cultural survey conducted in Japan and Korea. Findings indicate that the gratifications of online communities moderate the effects of online communities on social participation. Online communities are categorized into a real-group-based community and a virtual-network-based community. The membership of real-group-based online community is positively correlated with social bonding gratification and negatively correlated with information-seeking gratification. Japanese users prefer more virtual-network-based online communities, while their Korean counterparts prefer real-group-based online communities. Korean users are more active in online communities and seek a higher level of socializing gratifications, such as social bonding and making new friends, when compared with their Japanese counterparts. These results indicate that in Korea, personal relations via the online community are closely associated with the real-world personal relations, but this is not the case in Japan. This study suggests that the effects of the Internet are culture-specific and that the online community can serve a different function in different cultural environments.

PapersUses and gratification research using a typology of online communities: An exploratory study on Japanese and Korean students' communication behavior in online communitiesIn refereedAcademic JournalSingle-AuthorOGASAHARA, Morihiro;online community, typology, interest, small group, anonymity;2006/9～This paper introduces two typologies, 1) virtual-group based online community (the group formed only through the Internet) and 2) real-group based online community (the group formed by the relationship in the real world), to analyze communicated activities in various online communities. The comparative analysis suggests the conclusion of Japanese samples is resemble to one of Korean samples. In virtual-group online community, users are negative to communication but are gratified with information available there. On the other hand, ones in real-group online community are active to communication but are not satisfied with information well. It proposes that typological method can be used as a new way to analyze communicated activities of online communities.
