![]() Research Briefs Help Wanted: CEO. A great deal of media attention has focused lately on the disastrous reigns of CEOs such as Gilbert Amelio of Apple, Michael Ovitz of Disney, and John Walter of AT&T. Professor of Organizational Behavior Douglas T. Hall and Professor of Management Policy Fred K. Foulkes, both of the School of Management, have a solution to the problem of hiring a competent CEO: a well-informed, hard-working corporate board to guide the organization. Some guidelines for the board are:
Research by a national executive search association found that more than two out of three new CEOs recruited from outside the firm will fail. "CEOs don't like to face succession, as it implies mortality and the end of their reigns," says Hall. "Boards sometimes must force the issue -- but if they don't take the long-term view on the next generation of leadership, who will?" Tail(s) of a Comet. Boston University astronomers recently released a composite photograph showing three distinct tails extending from Comet Hale-Bopp. The photo confirms a discovery made in April by European astronomers, who found that the position of Hale-Bopp's tail was different from the ion and dust tails associated with most comets. "We made our observations in March at the McDonald Observatory in Fort Davis, Texas," says Jody Wilson, postdoctoral research associate at the Center for Space Physics. "We were analyzing our data in early April when reports came from the Canary Islands about the new tail. It then took just a day's work to get our results." Although sodium gas has been detected in previous comets, such as Halley's Comet in 1986, "the position of this sodium tail and its pattern of brightness away from the nucleus are very different from normal comet tails," says Michael Mendillo, CAS professor of astronomy. "This implies that the source of sodium is not necessarily on the nucleus, but extended from it." Wilson, an expert on the extended sodium atmosphere produced by volcanoes on Jupiter's moon Io, plans to use his models of sodium flowing from a tiny body to explore possible sources of Hale-Bopp's sodium tail. Images of Comet Hale-Bopp's three tails can be found online, at: http:// vega.bu.edu/cometc.gif (color) and http://vega.bu.edu/cometbw.gif (black-and-white).
