Modes of ambiguous communication

We study cheap talk communication in a simple two actions-two states model featuring ambiguous priors. First, we find that in equilibrium, S often mixes between messages triggering different beliefs and behavior by R while R also occasionally randomizes. We interpret randomization by respectively S and R as embodying two different modes of ambiguous communication. Second, we find that for sufficiently high ambiguity, more than two messages are often necessary to implement the optimal decision rule of S. If only two messages are available and S faces his preference twin, S may be unable to implement his optimal decision rule and influential communication may be altogether impossible. We stress the non replicability of these results within an expected utility environment. Third, we show that the addition of a little ambiguity may generate influential communication that is unambiguously advantageous to S

A Neural Network for Synthesizing the Pitch of an Acoustic Source

This article describes a neural network model capable of generating a spatial representation of the pitch of an acoustic source. Pitch is one of several auditory percepts used by humans to separate multiple sound sources in the environment from each other. The model provides a neural instantiation of a type of "harmonic sieve". It is capable of quantitatively simulating a large body of psychoacoustical data, including new data on octave shift perception.Air Force Office of Scientific Research (90-0128, 90-0175); Defense Advanced Research Projects Agency (90-0083); National Science Foundation (IRI 90-24877); American Society for Engineering Educatio

The Global People toolbook: managing the life cycle of intercultural partnerships

This Toolbook has been designed for those who are planning and running international projects and who feel a need for guidance. It has its origins in a major educational project, the eChina-UK Programme, that created new collaborations between UK and Chinese Higher Education Institutions around the development of e-learning materials. The rich intercultural learning that emerged from that programme prompted the development of a new and evidence-based set of resources for other individuals and institutions undertaking international collaborative projects. Although the main focus of the work is on intercultural effectiveness in international contexts, we believe that many of the resources have a more general value and are useful for those planning collaboration in any situation of diversity – national, regional, sectoral or institutional
