awa aa The following appeared in an article in the health section of a newspaper. “There is a common misconception that university hospitals are better than community or private hospitals. This notion is unfounded, however: the university hospitals in our region employ 15 percent fewer doctors, have a 20 percent lower success rate in treating patients, make far less overall profit, and pay their medical staff considerably less than do private hospitals. Furthermore, many doctors at university hospitals typically divide their time among teaching, conducting research, and treating patients. From this it seems clear that the quality of care at university hospitals is lower than that at other kinds of hospitals. ” ai Businesses and other organizations have overemphasized the importance of working as a team. Clearly, in any human group, it is the strong individual, the person with the most commitment and energy, who gets things done.” 数学 (本月jj)41.DS: 问在6月1号到8号有几个工作天(工作天=Mon~ Fri)? (1) 6月2号为Sat. or Sun.
