safety in numbers: more walkers and bicyclists, safer walking and bicycling.to examine the relationship between the numbers of people walking or bicycling and the frequency of collisions between motorists and walkers or bicyclists. the common wisdom holds that the number of collisions varies directly with the amount of walking and bicycling. however, three published analyses of collision rates at specific intersections found a non-linear relationship, such that collisions rates declined with increases in the numbers of people walking or bicycling.200312966006
california encephalitis virus, a newly described agent.in three cases of encephalitis in humans that occurred in the area where the newly described california virus was isolated from mosquitoes, serological evidence seemed to indict the california virus as the etiological agent. in the case of an infant with very severe disease, the serological evidence was convincing; the evidence was almost as strong in the case of a seven-year-old boy; the results in an adult were equivocal. inapparent infection in man is quite common as indicated by neutralizati ...195213009479
the 1952 outbreak of encephalitis in california; epidemiologic aspects.for the most part, epidemiologic phenomena observed in the outbreak of encephalitis in 1952 accorded with patterns that had been apparent in previous years. ninety-seven per cent of the 414 laboratory-confirmed cases of western equine and st. louis encephalitis in humans occurred in the 20 central valley counties. the cases of western equine encephalomyelitis in horses were generally scattered over the state. in the central valley most of the cases in horses were in animals less than two years o ...195313067018
preparing a new workforce.human caring, while instinctive, can also be taught, learned, and measured through the nursing education system. for decades information has been obtained that suggests people enter nursing because they value interpersonal relationships, altruism, and a desire to help others. building on this "caring ethic," nursing students can be professionally trained so that the very best in nursing comes through in their practice. by using nursing theory, students realize their potential while gaining all r ...200313677186
