Hamstrung by biases and limited facts, doctors routinely deliver shoddy care to old people. This guide shows how to reject that medical mindset and stay healthy longer. 相似文献

Small business crime has been largely ignored in American criminology; studies of nontraditional crime have focused mainly on corporate crime or on the misdeeds of employees pursuing personal gain. This paper calls for criminologists to redirect their efforts toward the systematic study of small business crime. In particular, it advocates in-depth qualitative studies that explore small business culture and opportunity structures, and that examine the networks of collusion that subvert the legitimate economy. The paper concludes with illustrations from an own story currently being shared with the author by a small businessman who participated for five years in an urban crime network that infiltrated the redistributive economy. 相似文献

The relation between domestic R&D and imports of technology is examined for 10 countries. Simple regressions revealed strong complementarity for each of the countries. Multiple regressions including GNP per capita and number of scientists and engineers were performed for the five countries with time series for all the variables. Strong complementarity was found between technology imports and domestic R&D and other variables for Japan and South Korea, weak for France, none for Germany and the US. Excluding government-financed R&D in the US resulted in a substitutive relation. Japan revealed a sharp decline in the ratio of technology payments to R&D spending; Korea is following in its steps. Complementarity appears to weaken in later stages as technology development strategies shift from dependent to imitative to autonomous or offensive technology development. 相似文献

With Bill Clinton's new reforms only a month away, the health-care system is on the operating table--and the doctors are under the knife. Americans have a love-hate relationship with physicians: they like the care that doctors provide but hold them to blame for the nation's health-care mess. NEWSWEEK looks at how the culture of medicine may change, assesses doctors' fears--and examines the brave new world of HMOs. 相似文献
