Companies’ efforts to manage their information practices to produce transparent privacy policies have yielded mixed results. Web retailers detail such practices in their online privacy policies, but most of the time this information remains invisible to consumers. This paper reports on research undertaken to determine whether a more prominent display of(More)
Feedback is viewed as an essential element of ubiquitous computing systems in the HCI literature for helping people manage their privacy. However, the success of online social networks and existing commercial systems for mobile location sharing which do not incorporate feedback would seem to call the importance of feedback into question. We investigated(More)

The stratum corneum is a complex tissue that is metabolically active, and undergoes dynamic structural modifications due to the presence of several self-regulating enzymatic systems. A large number of defensive (protective) functions are embodied in this tissue, each with its own structural and biochemical basis. Moreover, the stratum corneum is responsive(More)
