...Paul O. Wennberg '88 and Weld Professor of Atmospheric Chemistry James G. Anderson are part of a team that performed chemical research in a converted spy plane 70,000 feet above the earth's surface, seeking new answers to the problem of ozone depletion...
Supersonic aircraft, which currently include the Concorde and some military planes, produce these nitrogen radicals in their engines. "Estimates show that a 50 percent increase in nitrogen radicals [in the lower ozone layer] is expected from a fleet of supersonic aircraft," Wennberg says...
...Wennberg and Andersons' research addresses the fundamental question of whether Boeing, or any firm, can build such vast fleets of supersonic aircraft without doing irreparable damage to the lower ozone layer...
Meanwhile, strong evidence has emerged from health services researchers that, even without the pressure of cost-containment, there is reason to be concerned about the quality of at least some segments of the American health care system. Beginning a decade ago, Professor John Wennberg, now of Dartmouth Medical School, has systematically demonstrated levels of variation in the use of health care services that defy rational explanations...
Within the state of Maine, for example, Wennberg finds that, "by the time women reach 70 years of age in one hospital market, the likelihood they have undergone a hysterectomy is 20 percent, while in another market it is 70 percent." In Iowa, the probability of a prostatectomy in a man before the age of 85 years ranges from a low of 15 percent to a high of more than 60 percent in different hospital markets. Wennberg asserts that these enormous differences are based on "practical style," not on true differences in the morbidity of the populations...
