How Embeddedness Affects the Evolution of Collaboration: The Role of Knowledge Stock and Social Interactions

Science and technology are becoming increasingly collaborative. This paper aims to explore the factors and mechanisms that impact the dynamic changes of collaborative innovation networks. We consider both collaborative interactions of organizations and their knowledge element exchanges to reveal how social and knowledge network embeddedness affects the collaboration dynamics. Knowledge elements are extracted to present the core concepts of scientific and technical information, overcoming the limitations of using predefined categorizations such as IPC when representing the content. Based on multiple collaboration and knowledge networks, we then conduct a longitudinal analysis and apply a stochastic actor-oriented model (SAOM) to model network dynamics over different periods. The influence of network features and structures, individual node characteristics, and various dimensions of proximity on collaboration dynamics is tested and analyzed.Comment: 2 pages, 1 figure.

Cyberbullying-Entrenched or Cyberbully-Free Classrooms? A Class Network and Class Composition Approach

© 2015 International Communication Association. Cyberbullying threatens young people's well-being. This study is one of the first to examine cyberbullying from a social network perspective. The class-based friendship networks of 103 classes were reconstructed using peer-nomination questionnaires. Closeness centralization and the global clustering coefficient were calculated using social network analysis and subsequently entered into a Poisson-regression. The outcomes of these analyses show that in classes featured by high closeness centralization in the offline and online friendship network, more cyberbullying happens. Additionally, our analyses reveal that in classes featuring a high global clustering coefficient in the online network, less cyberbullying occurs. The composition of the class in terms of gender and ethnicity were not significantly associated with the number of cyberbullying incidents in class.status: publishe

Child online safety and parental intervention : a study of Sri Lankan internet users

Purpose: Today’s world of digital and mobile media does not require actual physical contact, between the suitable target and the motivated offender, as with traditional crime. In fact, as Mesch (2009) contends that the internet is not merely an information channel but it creates a new space of activities for children, where they are exposed to motivated offenders and the actors of fourth party. Therefore, for the sake of children’s safety, the practice of parental mediation control is increasingly becoming more pertinent everyday. Thus, the major purpose of this paper is to examine how parental mediation control in Sri Lanka is influenced by their internet self-efficacy, their experience as an online victim and their trust in online users. Design/methodology/approach: This paper uses a unique dataset of computer and internet users from Sir Lanka to examine parental intervention in their children’s online activities. Specifically, the dataset contains 347 responses from computer and internet users. To analyze our data we use a binary dependent (probit) model. Findings: The results show that such factors alter the baseline probability of parental intervention. However, some differences are found between younger and older parents, with the latter group responding more to trust in online users and victimization experience while the former is mainly driven from computer self-efficacy. In particular, the older group is less likely to trust online internet users in terms of never adding unknown persons in the social media. Finally, being self-employed and an older parent has a positive effect on the likelihood of adopting parental controls, possibly because of the non-pecuniary attributes of self-employment. Originality/value: This study adds to the emerging parental mediation control literature by looking at the likelihood of younger and older parents who were victims of cybercrimes, who have greater internet self-efficacy and lower online third party trust to adopt parental mediation control behaviours. Also another contribution to the literature is the role of occupation type on parental monitoring behaviours
