Anticipating deep autumn: a widening lens.
Medicine has become one of the most powerful influences of the twentieth century, and currently dominates how we approach and think about another powerful phenomenon: the aging of the world's population. Our reliance on the medical model, with its focus on pathology, physiology, and biomedical interventions, makes it difficult for aging men and women and those in the health care field who care ...
متن کاملStudying college alcohol use: widening the lens, sharpening the focus.
OBJECTIVE The study was designed to assess current trends in studying, and emerging approaches to furthering understanding of, college drinking. METHOD A literature review was conducted of findings and methods highlighting conceptual and methodological issues that need to be addressed.

متن کاملAn ultra - deep ISOCAM observation through a cluster - lens ?
We present results of ultra-deep ISOCAM observations through a cluster-lens at 7m and 15m with the Infrared Space Observatory (ISO) satellite. These observations reveal a large number of luminous Mid-Infra-red (MIR) sources. Cross-identiication in the optical and Near-Infrared (NIR) wavebands shows that about half of the 7 m sources are cluster galaxies. The other 7 m and almost all 15m sources...
متن کاملA possible gravitational lens in the Hubble Deep Field South
We model an apparent gravitational lens system HDFS 2232509–603243in the Hubble Deep Field South. The system consists of a blue V = 25 mag arc separated by 0. ′′9 from a red V = 22 mag elliptical galaxy. A mass distribution which follows the observed light distribution with a constant mass-to-light ratio can fit the arc component positions if external shear is added. A good fit is also obtained...
متن کاملA gravitational lens in the Hubble Deep Field
Cosmologically distant galaxies ought to act as multiply imaging gravitational lenses for a fraction ∼ 0.002−0.005 of background sources.[1, 2, 3] This prediction is being borne out by surveys of flat spectrum radio sources[4, 5] and optical surveys.[6, 7, 8] The incidence and character of strong gravitational lenses provide an important constraint on the source redshift distribution and world ...
