Investigation of peer effects on achievement with sample survey data on schools may mean that only a random sample of peers is observed for each individual. This generates classical measurement error in peer variables, resulting in the estimated peer group effects in a regression model being biased towards zero under OLS model fitting. We investigate the problem using survey data for England fr...

A vital requirement for e-commerce today is privacy. We explore the area of privacy for Agents in the Privacy Incorporated Software Agent (PISA) project. We first review existing privacy protection techniques: pseudonym systems, privacy enhancing technology (PET) and anonymous communication networks. We then propose a model for an Anonymous Internet Infrastructure (AII), an anonymous Internet b...
