We derive reliable entanglement witnesses for coarse-grained measurements on continuous variable systems. These witnesses never return a "false positive" for identification of entanglement, under any degree of coarse graining. We show that even in the case of Gaussian states, entanglement witnesses based on the Shannon entropy can outperform those based on variances. We apply our results to exp...

As a way to examine the nature of age-related differences in lineup identification accuracy, young (16-33 years) and older (60-82 years) witnesses viewed two similar videotaped incidents, one involving a young perpetrator and the other involving an older perpetrator. The incidents were followed by two separate lineups, one for the younger perpetrator and one for the older perpetrator. When the ...

Judges in the United States, the United Kingdom, and Canada have ruled that witnesses may not wear the niqab—a type of face veil—when testifying, in part because they believed that it was necessary to see a person’s face to detect deception (Muhammad v. Enterprise Rent-A-Car, 2006; R. v. N. S., 2010; The Queen v. D(R), 2013). In two studies, we used conventional research methods and safeguards ...

ny discussion of children as witnesses has to consider several areas. These include the competence of a child and the degree of stress which may result to the child from being a witness in court. In recent years a body of literature has been developed on children's memory and some of this can be applied to children as witnesses. In the meantime, more research is needed to identify which age gro...
