As more of our communication, commerce, and personal data goes online, credibility becomes an increasingly important issue. How do we determine if our e-commerce sites, our healthcare sites, or our online communication partners are credible? This paper examines the research literature in the area of web credibility. This review starts by examining the cognitive foundations of credibility. Other sections of the paper examine not only the general credibility of web sites, but also online communication, such as e-mail, instant messaging, and online communities. Training and education, as well as future issues (such as CAPTCHAs and phishing), will be addressed. The implications for multiple populations (users, web developers, browser designers, and librarians) will be discussed.

Individuals with Autism Spectrum Disorder (ASD) can face great challenges in learning and maintaining basic living skills. This not only reduces their possibilities of independent living and employment, but also continuously brings social and financial burdens to their caregivers/mentors. Although research has been proposed to help autism users, most of them focus on improving social and communication skills or providing help for emergency situations. In this paper, we propose a novel portable context-aware assistive system to help autism users in their daily activities such as cooking and cleaning. To make it easily accessible and cost effective, we employ mobile devices and cheap context sensors. Our care system has been implemented and tested under different settings, and a user study involving ten pairs of autism users and their caregiver/mentors has been carried out to evaluate our approach. User feedback is highly positive.
