Pecha Kucha: Bay 8

Abstract Following the success of Bay 9's Pecha Kucha, this week Bay 8 are providing the next instalment of the newly established tradition of Pecha Kucha. In 6m40s and 20 slides, each member of Bay 8 will introduce themselves, explaining their background and research interests, so you can put a name to the face, and chat after the event if you have common interests. These mini talks aim to support the collaborative nature of WAIS by introducing each member to the wider group. This week the bay members and Pecha Kuchas are: - The Public Health Analogy in Web Security (Huw) - Social Networking Features in Digital Behaviour Change Interventions (Roushdat) - Computers, Psychology and a lot of coffee (Anna) - Law, computer science and that annoying thing you have to say you’ve read before you can use a website (Emma)
