...Lloyd Peterson Jr., associate director for undergraduate admissions at Yale, said the New Haven school has not yet had time to fully discuss the chance of changing to Early-Decision...
...past three years, a number of parents' groups have organized against the program, protesting what they call the pseudo psychology at its core. Says Gary Peterson of Colorado, the founder of the fledgling national group Parents Against DARE: "Our schools are giving away more and more time to social- engineering programs that have not been sufficiently researched." Says Richard Evans of Northampton, Massachusetts: "DARE is awash in the touchy- feely stuff of the '70s. It's tricky and the kind of thing parents need to take a closer look at." Last week the critics of DARE received new ammunition...
...think he got framed," says Aarort T. Peterson '96. "I know there's plenty of evidence against him, but I couldn't see him killing anyone...
...involve heavy doses of chemicals, evidence from laboratory studies suggests there are also effects at lower concentrations. Endocrinologist David Crews has discovered, for example, that small PCB doses can dramatically influence the ratio of male to female offspring in red-eared slider turtles. When University of Wisconsin toxicologist Richard Peterson investigated the impact of dioxin on male rats, he found that the dose needed to cause reproductive-system problems was relatively high. "But when we exposed pregnant rats to a dose 1/100th as large," he says, "we found the male offspring showed signs of reproductive dysfunction," including smaller sex organs...
What is especially disturbing about Peterson's work is that the levels of dioxin needed to do that kind of damage were as low as 64 nanograms per kg of body weight -- only a little greater than the 5 or 10 nanograms of dioxin and comparable chemicals found in a typical kilogram of human tissue. It is not surprising that these compounds are so biologically active, since they are metabolized in a fashion similar to natural chemicals. Says Linda Birnbaum of the EPA's Health Effects Research Laboratory, who was one of the driving forces behind the agency's decision...
