...following excerpts are from a Crimson roundtable on industrial policy held last week with Robert B. Reich, lecturer on public policy and author of The New American Frontier, a leading book on the subject; Joseph L. Bower, professor of business administration and a member of Harvard's faculty seminar on industrial policy; and Lawrence J. Summers, professor of economics, who worked for two years on the staff of President Reagan's Council of Economic Advisors. Lavea Brachman and David L. Yermack moderated the discussion...
...University of Edinburgh, T.G.R. Bower and his associates have been conducting about 1,000 experiments a year on various infant abilities. One of their most startling claims is that babies can tell the gender of other infants they are looking at, and they prefer to look at those of their own sex. Bower made films of an infant boy and girl making various movements, and then deleted from the film a11 apparent signs of gender and even swapped their clothes. Some adult viewers had difficulty telling them apart...
...something about the way the filmed infants moved enabled a group of 13-month-old children to distinguish the boy from the girl. Bower is still trying to figure out how they do that...
Because checkerspots--a species which Bowers specializes in--feed on plants which contain secondary compounds called iridoid glycosoids, they are highly unpalatable to birds as well. These chemicals, Bower explains, may be toxic to some insects, but checkerspots have evolved mechanisms to excrete them quickly, sequester them in their exoskeleton or detoxify them. Thus the plant protects itself from most predators, and the butterflies render themselves "bitter" and in some cases nauseating. After feeding on members of these specialized species birds often throw...
Other aspects of Bower's research combine evolutionary, ecological and behavioral problems. "I'm going to start playing around this summer with a moth species that feeds on catalpa trees which contain large amounts of iridoid glycosoids," she says. The larvae of this species are gregarious and warningly colored but the adults are drab and cryptic. This type of life history suggests that the larvae are unpalatable but as they molt and become adults they are no longer unpalatable. "I don't exactly know what's going on with these guys, but I'm really psyched--it's really unusual...
