Abstract
The need for computer supported collaboration has grown over the last years and made collaboration an important factor within organizations. This trend has resulted in the development of a variety of tools and technologies to support he various forms of collaboration. Many collaborative processes, e.g. strategy building, scenario analysis, root cause analysis and requirements engineering, requires various collaboration support tools. Within these synchronous collaborative applications to create, evaluate, elaborate, discuss, and revise graphical models, e.g. data flow, fishbone and brainstorming diagrams, play an important role. Currently, the necessary tools are not integrated and flexible enough to support such processes. In this paper, we present a case study done to a synchronous collaborative brainstorming diagram editor - CLSD that is integrated in a flexible group support system. Our approach goes beyond the current state of the art as we can be seamlessly integrated with other collaboration support tools such as text-based brainstorming or voting.

Abstract
The new (e)commerce/(e)business paradigms forced enterprises to undertake important transformations and reorganizations. It happened with the web and will be repeated in the Cloud and social networks, following Eric Schmidt's (Google CEO) thoughts, "better thinking now on WWC - World Wide Computer, that is, what is behind u-commerce, ubiquity". The tourism is no more only a traditional commercial activity but ever more social- and information-oriented. The tourism services need to be effective to be aligned with tourist requirements. The globalization and easy access allows tourists to change their plans constantly. Dynamic services reconfiguration and resulting impact on their information systems need to be supported. The theme here presented explores new tourism services requirements as the ubiquity and dynamic reconfiguration, new brokering mechanisms, and reliable integration processes, and humanto-human synchronous collaboration allow the natural involvement of the tourist on the co-creation of his activity plan with other agents (humans). © 2012, IGI Global.

Abstract
In recent years the mass adoption of mobile devices and increasingly ubiquitous connectivity have contributed to a radical change in the way people interact with computer systems. Moreover cloud computing infrastructures have paved the way for the development of smart systems in such settings, whose goal is to provide a service to enhance user experience based on environment and user sensed data. In this context, there is a clear disconnection between the two streams that flow continuously between user and cloud-based systems. On the one hand, user- and environment-generated data is being, for the most part, disregarded by service providers. On the other hand, services offered do not address users' specific needs and preferences. In addition, service discovery is a cognitive demanding process and it may have detrimental consequences in user experience. In this paper we propose a user-centric framework that addresses the disconnection between these two streams: Cloud2Bubble. The framework facilitates the design and development of smart systems. It aims at leveraging existing technology, such as environment sensors and personal devices, to aggregate localised user-related data - defined as a bubble - into the cloud. This aggregation later supports the delivery of personalised services, contextually relevant to users. The delivery of services with such characteristics has the potential to enhance quality of experience and influence user behaviour. A first iteration of the platform was developed and an evaluation in a simulated environment was performed with encouraging results. Thus, the platform will be further expanded for instantiation and evaluation in the context of urban public transports. We intend to investigate the effects of relevant service delivery in terms of enhancement of quality of experience and influencing user behaviour. The delivery of a service with these characteristics presents benefits for both users and service providers. © 2012 ACM.
