Massively-parallel connectionist networks have traditionally been applied to constraint-satisfaction in early visual processing (Ballard, Hinton & Sejnowski, 1983), but are now being applied to problems ranging from the TravelingSalesman Problem to language acquisition (Rumelhart & MeClelland, 1986). In these networks, knowledge is represented by the distributed pat tern of activity in a large ...

SIR The article by Chaturvedi and McKeigue' fails to mention the danger of relying on the 1991 UK census as an accurate estimate of ethnic minority populations. Both Ballard and Kalra,2 in their discussion of the census nationally, and Glover,3 in his figures for the London areas of Camberwell and Hammersmith, point out the huge underrepresentation of black Caribbean men aged 25 to 44. Both rep...

Objective: Premature neonates are at greater risk for developmental problems such as cerebral palsy, delays in development, hearing problems, and problems seeing. The challenge encountering healthcare professionals who support preterm neonates and their parents is not only a matter of ensuring neonates survival, but to optimize infant development. Interventions to reduce adverse health outcomes...
