Audio-recordings and observations of recruitment appointments highlighted five key challenges to recruitment: a) there was little discussion of By-Band b) By-Band was not well integrated into the clinical service c) eligibili...

Recommender systems have shown to be valuable tools that help users find items of interest in situations of information overload. These systems usually predict the relevance of each item for the individual user based on their past preferences and their observed behavior. If the system’s assumption about the users’ preferences are however incorrect or outdated, mechanisms should be provided that...

For voters with “social” preferences, the expected utility of voting is approximately independent of the size of the electorate, suggesting that rational voter turnouts can be substantial even in large elections. Less important elections are predicted to have lower turnout, but a feedback mechanism keeps turnout at a reasonable level under a wide range of conditions. The main contributions of t...

We describe ongoing work toward development of a decision-theoretic agent to help users choose videos based on their preferences. The DIVA (DecisionTheoretic Interactive Video Advisor) system elicits user preferences using a case-based technique. Hard constraints are used to permit the user to communicate temporary deviations from his basic preferences. If the user is not happy with the system’...
