Interactive social networking sites (SNSs) have transformed information acquisition, communication, and lifestyles. However, the values and sustainability of SNSs largely depend on sustaining users' participation and their willingness to recommend the SNS to others. Research on SNSs has mainly explored the behavioral intentions of users using the social psychology approach. This study integrated the concepts of conformity tendency and perceived playfulness into the technology acceptance model to explain why people continue to use an SNS. We collected 671 valid questionnaires through the SNS site, Facebook, and used a structural equation model to conduct an empirical study. The results indicated that for conformity tendencies, informational influence promoted the continued intention to use SNSs through perceived usefulness, not through normative influence. Furthermore, perceived ease of use was the primary factor that predicted whether users would continue using SNSs, and perceived playfulness may have facilitated users' continued intentions to use SNSs.

Based on previous studies of EU-subsidized research joint ventures, R&D collaboration networks, and aerospace industry, this work raises and tests a set of hypotheses in order to check whether the European aerospace research area shows a scale-free topology. Its main focus concerns the application of a proper power-law detecting methodology to most important parameters: projects' and organizations' direct and indirect centrality, organizations' membership, and finally projects' size and fund. While previous studies of other EU-subsidized research joint ventures carried on the analyses with relatively simpler methods and tested only the power-law form, our work employs minimum and significance values calculations, and contrasts the power-law with other heavy-tailed distributions, which are widely analysed and discussed. The results clearly state that some parameters can be substantially assimilated to a power-law, while others only moderately or not at all. An explanation of such differences is provided and grounded on the relation between self-organization and scale invariance, mostly confirming a direct dependence of the latter from the former. However, the peculiarities of projects' size distribution make the interpretation of that relationship more problematic and suggest the need to carefully investigate the effect produced in each specific context by external constraints. Further, the implications of the scale-free topological properties—and in particular of their occurrence in the relationship between organizations' direct and indirect connectivity—are explored and discussed also respect to the effectiveness of European research policies. Besides enhancing the understanding of EU-subsidized research joint ventures in the European aerospace research area, our work contributes to investigate the more general issues of the relationship between self-organization and power-law, and between organizations' direct and indirect connectivity within inter-organizational networks. Finally, the paper underlines the high relevance of scale-free properties—and thus, the need to follow a proper detection methodology—by showing their relationships with resilience and sustainability of socio-economic systems.

Expatriate knowledge utilization and MNE performan A multilevel framework

We present a multilevel conceptual framework of expatriate knowledge utilization. Drawing from the resource-based view and multilevel approaches to expatriate utilization, we describe how individual expatriate characteristics (task-related and intercultural competencies, and motivation to transfer knowledge) and international adjustment, as well as subsidiary characteristics (absorptive capacity and knowledge sustainability) influence knowledge transfer effectiveness. We also draw from outward knowledge transfer and expatriate learning perspectives to address the cyclical nature of the process. As such, we include the effect of expatriate learning not only in continued knowledge flows to the subsidiary, but also in knowledge flows to the home division. We offer several implications for research on practice, including the notion that knowledge transfer to the subsidiary should continue upon repatriation, and that outward knowledge transfer can begin before repatriation. The framework reiterates that expatriates are valuable human capital and a source of sustained competitive advantage to the MNE.
