Previously, we showed using a computational agent-based model that a group of animals moving together can make a collective decision on direction of motion, even if there is a conflict between the directional preferences of two small subgroups of "informed" individuals and the remaining "uninformed" individuals have no directional preference. The model requires no explicit signaling or identifi...

This article studies the value of information in route choice decisions when a fraction of players have access to high accuracy information about traffic incidents relative to others. To model such environments, we introduce a Bayesian congestion game, in which players have private information about incidents, and each player chooses her route on a network of parallel links. The links are prone...

We propose a signalling model in which the central bank and firms receive information on cost-push shocks independently of each other. If the firms are rather unlikely to receive information directly, the central bank should remain silent about its own private information. If, however, firms are sufficiently likely to be informed,. it is socially desirable for the central bank to reveal its own...

Presently the conventional structure of personality, the Five-Factor Model (FFM), has faced criticism for inadequately capturing the full range of existing traits, particularly those reflecting antisocial behavior. The FFM has also not received sufficient application of genetically informed analyses to its extraction and validation. We explored these criticisms, and carried out four behavioral ...

The tension between two margins of information acquisition is studied in a canonical two-period model of portfolio choice. At the intensive margin, an investor chooses the amount of information. At the extensive margin, investors subscribe to the information source. Only if the number of informed investors at the extensive margin is sufficiently small does acquisition of additional information ...

Leadership is widespread across the animal kingdom. In self-organizing groups, such as fish schools, theoretical models predict that effective leaders need to balance goal-oriented motion, such as toward a known resource, with their tendency to be social. Increasing goal orientation is predicted to increase decision speed and accuracy, but it is also predicted to increase the risk of the group ...

SARA (Socially-Aware Robot Assistant) is an embodied intelligent personal assistant that analyses the user’s visual (head and face movement), vocal (acoustic features) and verbal (conversational strategies) behaviours to estimate its rapport level with the user, and uses its own appropriate visual, vocal and verbal behaviors to achieve task and social goals. The presented agent aids conference ...

BACKGROUND The main objective of this study was to explore the relationships between inpatients' social differentiation and satisfaction with the medical information delivered by caregivers. METHODS In four departments of a teaching hospital, patients were enrolled as well as their attending physician and one of the nurses assigned to them. Structured survey questionnaires were administered f...
