This paper responds to the Alpine Rendez-Vous (ARV) 'crisis' in technology enhanced learning (TEL). It takes a contested area of policy, rapid change in the National Health Service (NHS), and documents the responses to 'information overload' by group of General Practitioners Practices in the North of England. Located between the spaces identified by Traxler and Lally as 'competitive industrialisation' and Web 1.0, and the consumer/ customer focus and ubiquitous ownership enabled by portable and devices and web 2.0, in this work we see the parallels of the responses of publicly funded bodies moving towards privatisation as part of a neo-liberal agenda. Interviews with health professionals revealed marginalized spaces for informal learning in their workplaces; and a desire to build a community that would enable them to overcome the time/space barriers to networking. The EU Learning Layers Integrating Project develops mobile and social technologies that unlock and enable peer production within and across traditional workplace boundaries. Through the health professional narratives, we capture insights into their daily life, enable the articulation of their needs for an online 'Help-Seeking' networking service, underpinned by their desire to consult what Vygotsky calls 'the more capable peer'.

We analyze information diffusion using empirical data that tracks online communication around two instances of mass political mobilization that took place in Spain in 2011 and 2012. We also analyze protest-related communications during the year that elapsed between those protests. We compare the global properties of the topological and dynamic networks through which communication took place, as well as local changes in network composition. We show that changes in network structure underlie aggregated differences on how information diffused: an increase in network hierarchy is accompanied by a reduction in the average size of cascades. The increasing hierarchy affects not only the underlying communication topology but also the more dynamic structure of information exchange ; the increase is especially noticeable amongst certain categories of nodes (or users). Our findings suggest that the relationship between the structure of networks and their function in diffusing information is not as straightforward as some theoretical models of diffusion in networks imply.

This paper responds to the Alpine Rendez-Vous "crisis" in technology-enhanced learning. It takes a contested area of policy as well as a rapid change in the National Health Service, and documents the responses to "information overload" by a group of general practitioners practices in the North of England. Located between the spaces identified by Traxler and Lally as "competitive industrialisation" and web 1.0, and the consumer/ customer focus and ubiquitous ownership enabled by portable and devices and web 2.0, in this work we see the parallels of the responses of publicly funded bodies moving towards privatisation as part of a neo-liberal agenda. Interviews with health professionals (HPs) revealed marginalised spaces for informal learning in their workplaces, and a desire to build a community that would enable them to overcome the time/space barriers to networking. The EU Learning Layers Integrating Project develops mobile and social technologies that unlock and enable peer production within and across traditional workplace boundaries. Through the HP narratives, we capture insights into their daily life, which enable the articulation of their needs for an online "Help-seeking" networking service, underpinned by their desire to consult what Vygotsky calls "the more capable peer."

"We study the effect of transaction costs (e.g., a trading fee or a transaction tax, like the Tobin tax) on the aggregation of private information in financial markets. We implement a financial market with sequential trading and transaction costs in the laboratory. According to theory, eventually all traders neglect their private information and abstain from trading (i.e., a no-trade informational cascade occurs). We find that, in the experiment, informational no-trade cascades occur when theory predicts they should (i.e., when the trade imbalance is sufficiently high). At the same time, the proportion of subjects irrationally trading against their private information is smaller than in a financial market without transaction costs. As a result, the overall efficiency of the market is not significantly affected by the presence of transaction costs." [author's abstract]
