    The advances made in technology have unchained the user from the desktop into interactions where access is anywhere, anytime. In addition, the introduction of ubiquitous computing (ubicomp) will see further changes in how we interact with technology and also socially. Ubicomp evokes a near future in which humans will be surrounded by “always-on,” unobtrusive, interconnected intelligent objects where information is exchanged seamlessly. This seamless exchange of information has vast social implications, in particular the protection and management of personal information. This research project investigates the concepts of trust and privacy issues specifically related to the exchange of e-voting information when using a ubicomp type system

    <p>Abstract</p> <p>Background</p> <p>The composite graft from the conchal cartilage is a graft that is often used, especially in surgery on the nose, due to its capacity to resolve problems of cover and tissue deficit, arising from the removal of neoplasms or as the result of trauma, burns or following over-aggressive rhinoplasty. We have started to use skin-perichondrium-cartilage graft from the ear to cover large areas of the nose with very satisfying results as well as we describe in the reported clinical case.</p> <p>Methods</p> <p>The operation consisted of reconstruction of the cartilaginous nasal septum, which had previously been removed, using two vestibular labial mucosa flaps to reconstruct the mucosa, and cartilage from the ear conch for the cartilaginous septum. After this, the skin edges of the fistula were turned to recreate the inner lining of the nose and form a vascular base of wide area to accept the composite graft. The case concerns a female 74-year old patient who had undergone several oncological surgery for a relapsing basal cell carcinoma on the dorsum of the nose. The operation consisted of reconstruction of the cartilaginous nasal septum using two vestibular labial mucosa flaps to reconstruct the mucosa, and cartilage from the ear conch for the cartilaginous septum.</p> <p>Results</p> <p>The perichondrial cutaneous graft has shown in this surgical case very favorable peculiarities that make it usable even in facial plastic surgery.</p> <p>Conclusions</p> <p>We believe that the positive experience that we achieved in the use of composite grafts for the reconstruction of large areas of the nose could be interesting for others surgeons.</p

    M.: Addressing users’ privacy concerns for improving personalization quality: Towards an integration of user studies and algorithm evaluation

    No full text
    Abstract. Numerous studies have demonstrated the effectiveness of personalization using quality criteria both from machine learning / data mining and from user studies. However, a site requires more than a high-performance personalization algorithm: it needs to convince its users to input the data needed by the algorithm. Today’s Web users are becoming increasingly privacyconscious and less willing to disclose personal data. How can the advantages of personalization (and hence, of disclosure) be communicated effectively, and how can the success of such strategies be measured in terms of improved personalization quality? In this paper, we argue for a tighter integration of the HCI and computational issues involved in these questions. We first outline the problems for personalization that arise from the combination of users ’ privacy concerns and sites ’ current policies of dealing with privacy issues. We then describe the results of an experiment that investigated the effects of changes to a site’s interface on users ’ willingness to disclose data for personalization. This is followed by an overview of studies of the sensitivity of mining algorithms t
