The fragmented educator 2.0: Social networking sites,acceptable identity fragments,and the identity constellation

Social networking sites (SNS) have been used to support educational and professional endeavors. However, little research has been done to understand the relationship between educator identity and participation in SNS or to examine the implications that institutional regulation of such media may have upon educator identity. Using grounded theory, in this study we developed a framework for understanding how a group of teacher education students viewed their developing identities within social networking sites as they began the life transition to becoming educators. The theory that emerged from this study proposes that educator identity consists of a constellation of interconnected acceptable identity fragments, which are each intentional, authentic, transitional, necessarily incomplete, and socially-constructed and -responsive. This view of educator identity contrasts sharply with previous views of identity by highlighting the complicated, negotiated, and recursive relationship that exists between educator participation in SNS and educator identity. Additionally, this perspective suggests that educator participation in SNS is neither fully representative of authentic identity (as prominent SNS models imply) nor dramaturgical. These findings yield important implications for educators, researchers, educational institutions, lawmakers, and SNS developers alike, because they lead to a more sophisticated understanding of identity and online participation that is essential for developing mechanisms to support moral and legal judgments, professionalism, and social interactions relative to SNS.

A framework for mobile SNS advertising effectiveness: user perceptions and behaviour perspective

This study develops and empirically tests a framework for mobile social network service (SNS) advertising effectiveness. The study sets the advertising value, attitude towards advertising, and behavioural intentions as the key variables for the assessment of advertising effectiveness. Regarding antecedents of advertising effectiveness, the study identifies the salient attributes of mobile SNS advertising as social, mobile convenience, and active control; the main sub-values of mobile SNS advertising as informativeness, entertainment, and irritation.     

Teens’ concern for privacy when using social networking sites: An analysis of socialization agents and relationships with privacy-protecting behaviors

U.S. teens are spending substantial time on social networking sites (SNSs). Yet, only a few studies have documented teens’ privacy-protecting behaviors on SNSs. Using data of Facebook teen users and their parents in the U.S. from the Pew Internet’s Teens & Privacy Management Survey (N = 622), this study investigated the socialization agents of teens’ level of online privacy concern, and the relationship between teens’ level of online privacy concern and their privacy-protecting behaviors on SNSs. Based on path analysis results, this study identified parents and SNS use as the two significant socialization agents. In particular, this study revealed the role of parents’ privacy concern and the role of SNS use in motivating teens to increase online privacy concern, which, in turn, drives teens to adopt various privacy-setting strategies on SNSs and to set their Facebook profiles to private. Implications for policymakers and educators were discussed.     

Civic engagement among educated Chinese youth: The role of SNS (Social Networking Services), bonding and bridging social capital

This study conducted a stratified and cluster sampling on Chinese college students (N = 654) to investigate how SNS usages and social capital elicit impact on civic engagement. The results of path regression model shows that using SNS to meet new people is positively correlated with bonding and bridging social capital in the virtual world, using SNS to contact existing friends contributes to both bonding and bridging social capital in the real world. Online bonding and bridging social capital are positively related to online civic involvement, but not significantly related to offline civic behaviors. Offline bonding and bridging social capital are positively associated with offline civic participation, but not significantly related to online civic participation. The direct effect of using SNS to meet new social ties on civic engagement is partially mediated by social capital, whilst the effect of using SNS to connect friends on civic participation is completely mediated by social capital.
