Personalization in cultural heritage: the road travelled and the one ahead
Over the last 20 years, cultural heritage has been a favored domain for personalization research. For years, researchers have experimented with the cutting edge
technology of the day; now, with the convergence of internet and wireless technology, and the increasing adoption of the Web as a platform for the publication of information, the visitor is able to exploit cultural heritage material before, during and after the visit, having different goals and requirements in each phase. However, cultural heritage sites have a huge amount of information to present, which must be filtered and personalized in order to enable the individual user to easily access it. Personalization of cultural heritage information requires a system that is able to model the user
(e.g., interest, knowledge and other personal characteristics), as well as contextual aspects, select the most appropriate content, and deliver it in the most suitable way. It should be noted that achieving this result is extremely challenging in the case of first-time users, such as tourists who visit a cultural heritage site for the first time (and maybe the only time in their life). In addition, as tourism is a social activity, adapting to the individual is not enough because groups and communities have to be modeled and supported as well, taking into account their mutual interests, previous mutual experience, and requirements. How to model and represent the user(s) and the context of the visit and how to reason with regard to the information that is available are the challenges faced by researchers in personalization of cultural heritage. Notwithstanding the effort invested so far, a definite solution is far from being reached, mainly because new technology and new aspects of personalization are constantly being introduced. This article surveys the research in this area. Starting from the earlier systems, which presented cultural heritage information in kiosks, it summarizes the evolution of personalization techniques in museum web sites, virtual collections and mobile guides, until recent extension of cultural heritage toward the semantic and social web. The paper concludes with current challenges and points out areas where future research is needed
A Survey of Green Networking Research
Reduction of unnecessary energy consumption is becoming a major concern in
wired networking, because of the potential economical benefits and of its
expected environmental impact. These issues, usually referred to as "green
networking", relate to embedding energy-awareness in the design, in the devices
and in the protocols of networks. In this work, we first formulate a more
precise definition of the "green" attribute. We furthermore identify a few
paradigms that are the key enablers of energy-aware networking research. We
then overview the current state of the art and provide a taxonomy of the
relevant work, with a special focus on wired networking. At a high level, we
identify four branches of green networking research that stem from different
observations on the root causes of energy waste, namely (i) Adaptive Link Rate,
(ii) Interface proxying, (iii) Energy-aware infrastructures and (iv)
Energy-aware applications. In this work, we do not only explore specific
proposals pertaining to each of the above branches, but also offer a
perspective for research.Comment: Index Terms: Green Networking; Wired Networks; Adaptive Link Rate;
Interface Proxying; Energy-aware Infrastructures; Energy-aware Applications.

Semi-autonomous, context-aware, agent using behaviour modelling and reputation systems to authorize data operation in the Internet of Things
In this paper we address the issue of gathering the "informed consent" of an
end user in the Internet of Things. We start by evaluating the legal importance
and some of the problems linked with this notion of informed consent in the
specific context of the Internet of Things. From this assessment we propose an
approach based on a semi-autonomous, rule based agent that centralize all
authorization decisions on the personal data of a user and that is able to take
decision on his behalf. We complete this initial agent by integrating
context-awareness, behavior modeling and community based reputation system in
the algorithm of the agent. The resulting system is a "smart" application, the
"privacy butler" that can handle data operations on behalf of the end-user
while keeping the user in control. We finally discuss some of the potential
problems and improvements of the system.Comment: This work is currently supported by the BUTLER Project co-financed

Unleashing Youth Potential: Understanding and Growing Youth Participation in Philanthropy and Volunteerism
This paper attempts to situate youth in philanthropy in the context of the organizational culture and practices of Canadian community foundations. It will explore the challenges and opportunities presented by engaging young people in community foundations, based on the development of Vancouver Foundation's Youth in Philanthropy program in British Columbia, and its dissemination elsewhere in Canada. Youth in Philanthropy is a province-wide program established by Vancouver Foundation in late 1997 designed to involve young people in their communities and in philanthropy through involvement with local community foundations
