Search for Neutrinoless Double-Beta Decay with the Upgraded EXO-200 Detector.

Results from a search for neutrinoless double-beta decay (0νββ) of ^{136}Xe are presented using the first year of data taken with the upgraded EXO-200 detector. Relative to previous searches by EXO-200, the energy resolution of the detector has been improved to σ/E=1.23%, the electric field in the drift region has been raised by 50%, and a system to suppress radon in the volume between the cryostat and lead shielding has been implemented.

Prevention science and neighborhood influences on low-income children's development: theoretical and methodological issues.

Despite the rapid growth of research on neighborhood influences on children, little of this research may be useful to prevention scientists. Most studies have ignored processes by which neighborhood conditions influence individual outcomes. To encourage neighborhood research that can better guide the development of preventive interventions, we propose a model that focuses attention on mediating and moderating processes, is appropriate for studies interested in individual differences in outcomes, acknowledges the transactions between residents and neighborhoods, and is sensitive to how neighborhood influences may differ for children at different developmental stages.

"New" long-stay psychiatric patients: a national sample survey of fifteen mental hospitals in England and Wales 1972/3.

Four hundred "new" long-stay patients were studied and assessments of their needs for treatment and accommodation were made. About one third appeared to need further care in hospital. A further third could possibly be discharged if suitable accommodation in the community were available: most of this group were more handicapped than present residents in hostels.
