Emphasizing a common group identity is often suggested as a way to promote between-group helping. But recently, researchers have identified a set of strategic motives for helping other groups, including the desire to present the own group as warm and generous. When the motive for helping is strategic, a salient common identity should reduce the willingness to help another group, because the hel...

the diagnostic accuracy of single photon emission computed tomography (spect) is profoundly influenced by attenuation phenomenon. soft tissue attenuation degrades cardiac spect image quality, thereby decreasing the possibility of the detection of the lesions. a variety of correction techniques based on different assumptions have been used to reduce the impact of attenuation. several types of sy...

The introduction of dynamic oracles has considerably improved the accuracy of greedy transition-based dependency parsers, without sacrificing parsing efficiency. However, this enhancement is limited to projective parsing, and dynamic oracles have not yet been implemented for parsers supporting non-projectivity. In this paper we introduce the first such oracle, for a non-projective parser based ...
