[单项选择]The Supreme Court’’ s decisions on physician-assisted suicide carry important implications for how medicine seeks to relieve dying patients of pain and suffering.
Although it ruled that there is no constitutional right to physician-assisted suicide, the Court in effect supported the medical principle of "double effect," a centuries-old moral principle holding that an action having two effects―a good one that is intended and a harmful one that is foreseen―is permissible if the actor intends only the good effect.
Doctors have used that principle in recent years to justify using high doses of morphine to control terminally iii patients’’ pain, even though increasing dosages will eventually kill the patient.
Nancy Dubler, director of Montefiore Medical Center, contends that the principle will shield doctors who" until now have very, very strongly insisted that they could not give patients sufficient medication to control their pain if that might hasten death."

Why aren’t the University Colleges and Institutes just called "University" The simpler answer is that, with a few %xceptions, the University Colleges and Institutes do not usually award all their own degrees.
