Through an analysis of recent data on adults' and children's computer use experiences, this DataWatch shows that computers the Internet is widespread significant percentages public are already using to get health information. The surveys also show a useful vehicle for reaching large numbers lower-income, less-educated, minority Americans. However, substantial digital divide continues characterize use, with lower-income blacks especially affected. Implications future communication explored.

This paper examines the depth and breadth of public backlash against managed care reasons for it. We conclude that is real influenced by at least two principal factors: (1) A significant proportion Americans report problems with plans; (2) perceives threatening dramatic events in have been experienced just a few. In addition, concern driven fear regardless how well their plans perform today, might not be available or paid when they are very sick.

It finds that public has a bleaker picture what happened economically to average family and is more pessimistic than most economists about intermediate future. The cites different reasons do for why economy not doing better. Also, individuals' perceptions their own economic experiences yield set beliefs conditions described in official statistics. authors offer possible explanations perception gap between...

We have used the Very Long Baseline Array (VLBA) at 43, 23, and 15 GHz to measure solar gravitational deflection of radio waves among four sources during an 18 day period in 2005 October. Using phase-referenced interferometry fit measured phase delay propagation equation parameterized post-Newtonian formalism, we determined parameter γ = 0.9998 ± 0.0003 (68% confidence level), agreement with general relativity. The results come mainly from 43 observations where refraction effects corona were...

Broadband phase modeling was used calibrate varying dispersive effects ionosphere and remove resulting errors from phase-referenced VLBI data. The parallaxes have a typical accuracy 100 μas or better, yielding as 2%. also report new proper motion these pulsars, 400 yr-1 better.
