Manson, chief of preventive medicine at Harvard's Brigham and Women's Hospital, says women employees are less likely than men to ask her for pay raises, a phenomenon she says may explain results of a new study showing women doctor-researchers get paid substantially less than their male counterparts. The study involving 800 doctors nationwide appears Wednesday, June 12, 2012, in Journal of the American Medical Association. (AP Photo/Elise Amendola, File)
