Speech register research shows that humans are adept at finetuning components of their speech to accommodate the needs audience of the audience, suggesting that they have a model of human communication needs. However, when that audience is a computer rather than another human, such a model may be invalid. Here we examine humans’ speech to other humans or an auditory-visual avatar before and aft...

Utilizing Bayesian beliefnetworks as a model of causality, we examined medical students' ability to discover causal relationships from observational data. Nine sets ofpatient cases were generatedfrom relatively simple causal beliefnetworks by stochastic simulation. Twenty participants examined the data sets and attempted to discover the underlying causal relafionships. Performance was poor in g...

The prices of the option and futures of a stock both reflect the market’s expectation of futures changes of the stock’s price. Their prices normally align with each other within a limited window. When they do not, arbitrage opportunities arise: an investor who spots the misalignment will be able to buy (sell) options on one hand, and sell (buy) futures on the other and make risk-free profits. H...

This paper reviews emerging computer techniques for discovering knowledge from data bases and their application to various sets of separation data The data sets include the separation of a diverse range of analytes using either liquid gas or ion chromatography The main conclusion is that the new techniques should help to close the gap between the rate at which chromatographic data is gathered a...

This paper presents a case study on the use of an alternative method of computer support to that normally used, one that uses voting as a tool for social rather than rational choice. This voting before discussion (VBD) method is indicated in cases where agreement is an important group output, or where interpersonal conflict is creating problems in meetings. Given that participants are warned to...
