This paper extends Burdett and Coles (2003)’s search model to two types of workers and firms and derives the equilibrium earnings distributions for both types of workers. It is proven that minority workers have a higher unemployment rate than majority workers; discriminating firms make lower profit than non-discriminating firms; offers to minority workers by non-discriminating firms are consist...

Many topological measures have been introduced in the literature to characterize topological prope...

This paper aims to address the problem of anomaly detection and discrimination in complex behaviours, where anomalies are subtle and difficult to detect owing to the complex temporal dynamics and correlations among multiple objects’ behaviours. Specifically, we decompose a complex behaviour pattern according to its temporal characteristics or spatial-temporal visual contexts. The decomposed beh...

Gravity is a crucial environmental factor regulating plant growth and development. Plants have the ability to sense a change in the direction of gravity, which leads to the re-orientation of their growth direction, so-called gravitropism. In general, plant stems grow upward (negative gravitropism), whereas roots grow downward (positive gravitropism). Models describing the gravitropic response f...

Perception of global patterns requires the integration of local orientation information across space. The present study examined whether this integration ability declines in older age. We measured contrast thresholds for discriminating the global orientation of a "C" shaped contour against a blank background in younger and older subjects. Performance of younger subjects improved when the elemen...

Evidence remains mixed about whether individuals with autism look less to eyes and whether they look more at mouths. Few studies have examined how spontaneous attention to facial features relates to face processing abilities. This study tested the ability to discriminate gender from facial features, namely eyes and mouths, by comparing accuracy scores of 17 children with autism and 15 adults wi...

The ways of binding optically active ligands, mainly of the amino acid type, to cross—linked polymers of styrene, acrylamide or glycidylmethacrylate are reviewed. When coordina— ted to transition metal ions, these polymers display a high discriminating ability in sorption of optical isomers of corn— pounds capable of forming mixed—ligand complexes. The kinetic performance of the ligand—exchangi...

The paper reports the University of Waterloo participation in the opinion and polarity tasks of the Blog track. The proposed method uses a lexicon built from several linguistic resources. The opinion discriminating ability of each subjective lexical unit was estimated using the Kullback-Leibler divergence. The KLD scores of subjective words occurring within fixed-size windows around instances o...
