Faculty members with industrial research support are at least as productive academically as those without such support and are more productive commercially. However, faculty members who have research relationships with industry are more likely to restrict their communication with colleagues, and high levels of industrial support may be associated with less academic activity without evidence of proportional increases in commercial productivity.

After more than a decade of sustained interaction, universities and industries seem to have formed durable partnerships in the life sciences, although the relationships may pose greater threats to the openness of scientific communication than universities generally acknowledge. However, industrial support for university research is much smaller in amount than federal support, and companies are unlikely to be able to compensate for sizable federal cutbacks.

Trends in primary care practice reflect changes in society and in the US health care system, including demographic changes, an emphasis on prevention, and the growth of managed care. The increasing role of managed care, with its emphasis on increased productivity, appears at odds with primary care physicians' increasing responsibility for prevention and the associated increase in the duration of primary care visits.

Parents of children with a chronic condition were much less likely than other parents to switch to a gatekeeping plan. Switching to gatekeeping was associated with reduced visits to specialists but did not increase the involvement of primary care physicians in the management of children with chronic conditions. The implications of these findings for the health of children are unknown.

*P values are based on 2 tests for categorical variables and t tests for continuous variables.

Background: The environment in which medicine is practiced has changed in the past 2 decades, but little information has been available on how the day-today practice of primary care for children has changed during this period. Objective: To identify aspects of primary care practices for children that are undergoing substantial changes.
