Serendipity refers to unexpected encounters with ideas or insights and their intentional application to achieve favorable outcomes. Despite extensive prior studies, the concept lacks theoretical logic and empirical validation regarding the role of an intentional act in the relationship between serendipitous encounters and their favorable outcomes. Drawing from self-determination theory, we develop a model that highlights the role of needs satisfaction in explaining this relationship. Positioning the empirical context to fortunate discoveries of information and social connections in professional use of Twitter, we validate the model by a cross-sectional survey study of 473 users. The model builds on the observation that individuals’ serendipitous encounters are associated with Twitter-enabled innovation, that is, a contextualized form of task innovation. The study findings support the research model revealing that serendipitous encounters are positively associated with needs satisfaction and that needs satisfaction is positively associated with Twitter-enabled innovation. In other words, fortunate discoveries of new information and contacts increase Twitter users’ intent to utilize the platform in new ways to accomplish work when the three key psychological needs of autonomy, competence, and relatedness are satisfied.

Background: A wide variety of information and communication technologies (ICTs) is increasingly embedded into numerous facets of everyday life. Young people, in particular, are often viewed as eager and skilful users of new ICTs who have various educational and leisure-related purposes for ICT use. Although school and home lives have traditionally been viewed as separate, ICT use has blurred the lines between these environments. This study focuses attention on the negotiation of this 'grey zone' within the school setting, in terms of teachers' practices around students' online interactions. Purpose: This study sought to gain insight into teachers' perceptions of the challenges related to students' online interactions and how these become visible in the school context. This included exploring strategies identified by teachers in efforts to surmount difficulties. Methods: Data collection involved semi-structured interviews with 15 teachers in Finland working in primary and/or lower secondary education. The transcribed data were analysed qualitatively, using a thematic approach. Findings: According to the teachers, there were significant challenges associated with young people's online interactions that affected their students and the flow of school life, such as online conflicts and dysfunctional behaviour in messaging groups. Although teachers found that the boundaries and the obscurity of their roles made it difficult to address some situations, they nonetheless identified strategies to overcome challenges, often including collaboration with students and parents. Conclusions: The study highlights how students' online interactions can affect the ways that teachers view themselves and their roles as educators. Given the pace with which ICT, and young people's use of it evolves, the study suggests that there is a need for frequently reviewed guidelines or practices that help clarify the roles of different actors in relation to the realities of students' ICT use.

Purpose: The purpose of this study is to investigate the barriers that prevent workers in the software industry from experiencing flow in their work. Design/methodology/approach: This study was conducted by using a qualitative critical incident technique-inspired questionnaire. Findings: The findings suggest that workers in the software industry perceive that the most obvious obstacles to experiencing flow are related to work not presenting enough cognitive challenges and situational barriers related to the characteristics of the job (e.g. workdays having too many interruptions and distractions, timetables often being considered too tight for creative exploration and problem solving and having negative user experiences with development tools). Originality/value: The findings provide insights into flow barriers, specifically barriers that prevent workers in the software industry from experiencing flow.
