Previous papers on testing for statistical discrimination and employer learning require variables that employers do not observe directly, but are observed by researchers or data on employer-provided performance measures. This paper develops a test that does not rely on these speci…c variables. The proposed test can be performed with individual-level cross-section data on employment status, expe...

Sometimes the leaders of ethnic minority groups behave in a way that may promote xenophobia. A simple two-subject model is used to find out when this behaviour is rational. The conditions are briefly discussed with reference to the Italian case. An appendix illustrates the definition of xenophobia adopted in the paper. JEL Classification number: D70

The ability to discriminate between different facial expressions is fundamental since the first stages of postnatal life. The aim of this study is to investigate whether 2-days-old newborns are capable to discriminate facial expressions of emotions as they naturally take place in everyday interactions, that is in motion. When two dynamic displays depicting a happy and a disgusted facial express...

Knowledge representation was used to characterize beliefs in patients with Environmental Illness/Multiple Chemical Sensitivity (EI/MCS). EI/MCS patients, allergy and asthma patients, doctors and controls made relatedness judgments on concepts relevant to EI/MCS. Associative networks showed that EI/MCS patients viewed these concepts differently from others. Multiple chemical exposure was central...

Since its introduction in 2006, Nintendo’s Wii remote game controller (wiimote) has been used in many research projects. Most of the time however, only its accelerometer data is actually used. We present a system that allows 3D tracking of the wiimote using its built-in camera, active IR markers and a modified ARToolkit library. Multiple markers are then discriminated by their blinking patterns...
