Abstract
The present study investigated how vivid, i.e. sensorially rich platforms influence the urge to buy impulsively in e-commerce environments. A stimulus - organism - response model was assessed in an experiment involving two groups, one experiencing a vivid platform and the other a more informational one. The response was posited to be mediated by the affect elicited during the experience. The results show that the urge to buy was not prevalent, but it was significantly higher in the group exposed to the vivid site. The variance of urge to buy was largely accounted buy the variance of positive arousal (delight). Negative affect, as well as low arousal positive affect (relax) have small negative effects on the urge. These results confirm our expectation that a simple distinction between negative and positive affect is insufficient to predict the urge, since the level of arousal also plays a fundamental role to trigger the urge.

Abstract
Current information and communication technologies, including the internet and its services (web 2.0, email, conferences at a distance, etc.) have opened new perspectives in the field of education, by promoting communication and interaction between all participants at a distance. It is not the technology itself that will define the quality of teaching and learning in distance education, but the methodological approach that supports it. This paper aims to propose a methodological framework to implement in distance education modules supported by online pedagogy elements linked to innovative teaching methodologies. Its goal is to bring some contributions to those who are in charge of course design, providing a useful framework to improve active and technology enhanced collaborative learning in similar environments.

Abstract
With the emergence of the Industry 4.0 concept, or the fourth industrial revolution, the industry is bearing witness to the appearance of more and more complex systems, often requiring the integration of various new heterogeneous, modular and intelligent elements with pre-existing legacy devices. This challenge of interoperability is one of the main concerns taken into account when designing such systems-of-systems, commonly requiring the use of standard interfaces to ensure this seamless integration. To aid in tackling this challenge, a common format for data exchange should be adopted. Thus, a study to select the foundations for the development of such a format is hereby presented, taking into account the specific needs of four different use cases representing varied key European industry sectors.

Abstract
In this paper we introduce the problem of planning for perception of a target position. Given a sensing target, the robot has to move to a goal position from where the target can be perceived. Our algorithm minimizes the overall path cost as a function of both motion and perception costs, given an initial robot position and a sensing target. We contribute a heuristic search method, PA*, that efficiently searches for an optimal path. We prove the proposed heuristic is admissible, and introduce a new goal state stopping condition.
