The other-race effect (ORE) refers to the phenomenon that recognition memory for other-race faces is worse than for ownrace faces. We investigated whether White Germans exhibited an ORE towards Turkish or Arabic faces using a multinomial processing tree model (MPT), the two-high threshold model of recognition memory with three response categories (old, skip, and new). Using an MPT enabled us to...

We consider a high dimensional regression model with a possible change point due to a covariate threshold and develop the lasso estimator of regression coefficients as well as the threshold parameter. Our lasso estimator not only selects covariates but also selects a model between linear and threshold regression models. Under a sparsity assumption, we derive non-asymptotic oracle inequalities f...

Discussion Papers are a series of manuscripts in their draft form. They are not intended for circulation or distribution except as indicated by the author. For that reason Discussion Papers may not be reproduced or distributed without the written consent of the author. Abstract The significant impact of international tourism in stimulating economic growth is especially important from a policy p...

I review lattice QCD results relevant to the recently discovered hadrons: X(3782), Y (4260), and Ds(2317), because these seem, to me at least, to be the most interesting states from the perspective of solving and understanding QCD . The physical picture behind lattice QCD calculations is that an interpolating operator creates a hadron in the QCD vacuum. and after a specific time interval the ha...

A close correlation between Stiles's increment threshold (pi-mechanism) approach and color discrimination at threshold was found: a sharp transition from detection of two lights via two pi-mechanisms (pi 1 and pi 4) to detection via only one pi-mechanism (pi 1) was paralleled by a sharp decline from excellent discrimination between those two lights (even with the rods bleached) to no discrimina...

This paper studies a program that extends the maximum duration of unemployment benefits from 30 weeks to 209 weeks. Interestingly, this program is targeted to individuals aged 50 years or older, living in certain eligible regions in Austria. In the evaluation, I use sharp discontinuities in treatment assignment at age 50 and at the border between eligible regions and control regions to identify...
