abstract = {Undoubtedly, Location-based Social Networks (LBSNs) provide an interesting source of geo-located data that we have previously used to obtain patterns of the dynamics of crowds throughout urban areas. According to our previous results, activity in LBSNs reflects the real activity in the city. Therefore, unexpected behaviors in the social media activity are a trustful evidence of unexpected changes of the activity in the city. In this paper we introduce a hybrid solution to early detect these changes based on applying a combination of two approaches, the use of entropy analysis and clustering techniques, on the data gathered from LBSNs. In particular, we have performed our experiments over a data set collected from Instagram for seven months in New York City, obtaining promising results.},

abstract = {Many MOOCs are being designed replicating traditional passive teaching approaches but using video lectures as the means of transmitting information. However, it is well known that learning-by-doing increases retention rates and, thus, allows achieving a more effective learning. To this end, it is worth exploring which tools fit best in the context of each MOOC to enrich learners' experience, including built-in tools already available in the MOOC platform, and third-party external tools which can be integrated in the MOOC platform. This paper presents an example of the integration of a software development tool, called Codeboard, in three MOOCs which serve as an introduction to programming with Java. We analyze the effect this tool has on learners' interaction and engagement when running the MOOCs in synchronous (instructor-paced) or asynchronous (self-paced) modes. Results show that the overall use of the tool is similar, regardless of the course running mode, although in the case of the synchronous mode the use of the tool is concentrated in a shorter period of time. Results also show that in the synchronous mode there is a higher percentage of accesses to the tool from registered learners (who can save their advances and continue the work later); this finding suggests that learners in the synchronous running mode are more engaged with the MOOC.},

abstract = {During the past years we have assisted to the huge diffusion of Cloud based Services, but security and privacy are still an issue in the Cloud due to a problem of trust endemic in the Cloud paradigm; users who have subscribed some kind of Cloud service must fully trust their providers. In this paper we propose a new, yet simple way to guarantee privacy for end user's data and operations. We propose to use an application inside an STB as single point of concentration for user's Cloud services accounts. Thus, a higher degree of privacy could be achieved by splitting user's data and operations over multiple identities and even over multiple providers' networks. In this article we depict, as example, the case of on-line storage and synchronization service.},

abstract = {Multimedia availability is exceeding our capacity of management in home environment and outside it. For that reason, solutions as Media Cloud have brought the concept of Cloud Computing to home environments. Media Cloud provides a comprehensive and efficient solution for managing content among federated home environments. However, when consuming those contents outside a home environment some problems should be addressed as dealing with limited devices and protecting user generated and commercial contents from eavesdroppers. This article describes a solution that enables limited devices to access contents located in private clouds, as Media Cloud, with the cooperation of network providers.},
