Never Look Back: An Alternative to Centering
I propose a model for determining the hearer's attentional state which depends solely on a list of salient discourse entities (S-list).

A key question for researchers is whether those who have recovered from depression also exhibit attentional biases, and if so, how similar these biases are to those who are currently depressed. To address this ques...

Better data-collection facilities and cryogenic techniques, coupled with powerful programs for data processing, phasing, density modification and automatic model buil...
