ABSTRACT
We demonstrate broadband polarization-entangled photon pair generation in a poled fiber phase matched for Type II downconversion in the 1.5 µm telecom band. Even with signal-idler separation greater than 100 nm, we observe fringe visibilities greater than 97% and tangle greater than 0.8. A Hong-Ou-Mandel interference experiment is also used to experimentally confirm the broadband nature of the entanglement.
ABSTRACT
BACKGROUND: Applied behaviour analysis (ABA) reduces challenging behaviour in people with intellectual disability. There is interest, however, in whether such interventions reduce carer burden and increase community participation in this group. METHODS: A 6-month randomised controlled trial was followed by a longer-term naturalistic follow-up of participants. We studied the impact of the challenging behaviour on the carers and on the daily activities of the participants measured by the Carer Uplift and Burden Scale and Guernsey Community Participation and Leisure Assessment respectively. RESULTS: Both community participation and carer burden improved at 6 and 24 months. Burden showed significant reduction in family carers compared with paid carers. There was no significant intervention effect on the variables under consideration. CONCLUSIONS: ABA appears to be no more effective than standard care in improving social outcomes in people with intellectual disabilities and challenging behaviour but this requires further examination in a larger trial.

The effect of electroconvulsive therapy (ECT) and antidepressant drugs on eye blink rates and on a measure of psychomotor retardation was compared in two samples of neuroleptic-free subjects suffering from DSM III major depression and matched on admission by Hamilton and psychomotor retardation scores. Both treatments caused a significant change in eye blink and psychomotor retardation measures. There was no significant difference between treatment groups, although the ECT-treated subjects included those with the largest eye-blink increases. There was no correlation between Hamilton scores and eye blink rates or psychomotor retardation scores for any of the groups or stages of treatment.
