单选题Chris Hrapko isn"t afraid of tough conversations. As the founder of a nonprofit social-service agency, she battles bureaucracies on behalf of the homeless and the working poor. But there is one conversation Hrapko avoided. When her 92-year-old mother fell and broke her hip earlier this year, Hrapko knew it would affect her independent mother"s living arrangements and health. But Hrapko, 51, was clueless about her mom"s wishes. "We talked about a lot of things," she says, "but we never talked about a future in which my mom faced a problem that could leave her disabled, bedridden or on life support. " A recent survey by AARP found that nearly 70 percent of adult children have not talked to their parents about issues related to aging. Some children avoid this most intimate of conversations because they believe their parents don"t want to talk. Others think they know what their parents want. And some simply don"t want to face the very real truth that if you are lucky enough to have parents who live well into their senior years, chances are good that disease, injury, frailty, even loneliness, will affect a parent"s well-being. While it"s clear that having a conversation with aging parents is important, there is no blueprint on how to do it well. What works for one family may not work for yours. The key is to be flexible, says Mary Anne Ehlert, founder of Chicago-based Protected Tomorrows, an advocacy firm for families with special needs. She has found that one of the best ways to get the conversational ball rolling is to talk about your parents" and what they would do if faced with a situation in which people they loved could no longer care for themselves. " Ask your parents for advice; seek their wisdom in helping you help them," Ehlert says. It"s also important for adults to be honest about what they are prepared to do for their parents. As parents age and become frail, many will need help with personal hygiene. It"s these kinds of issues that can make the most devoted child balk. "Before you agree to be a caregiver, make sure you understand what you may be in for," says Monika White, president-elect of the National Association of Professional Geriatric Care Managers. " Adult children need to acknowledge their own limitations and then be prepared to make some type of arrangement for the things they simply can"t do. " Realize that there is no such thing as one conversation about aging. " No one resolves the future in one afternoon of talk," says psychologist Brian Carpenter of Washington University in St. Louis. "It"s a process. " One strategy is to schedule time to talk about a specific subject, such as wills or living arrangements.

单选题Moral responsibility is all very well, but what about military orders? Is it not the soldier's first duty to give instant obedience to orders given by his military superiors? And apart from duty, will not the soldier suffer severe punishment, even death, if he refuses to do what he is ordered to do? If, then, a soldier is told by his superior to burn this house or to shoot that prisoner, how can he be held criminally accountable on the ground that the burning or shooting was a violation of the laws of war? These are some of the questions that are raised by the concept commonly called "superior orders", and its use as a defense in war crimes trials. It is an issue that must be as old as the laws of war themselves, and it emerged in legal guise over three centuries ago when, after the Stuart restoration in 1660, the commander of the guards at the trial and execution of Charles I was put on trial for treason and murder. The officer defended himself on the ground "that all he did was as a soldier, by the command of his superior officer whom he must obey or die," but the court gave him short shrift, saying that "when the command is traitorous, then the obedience to that command is also traitorous." Though not precisely articulated, the rule that is necessarily implied by this decision is that it is the soldier's duty to obey lawful orders, but that he may disobey — and indeed must, under some circumstances — unlawful orders. Such has been the law of the United States since the birth of the nation. In 1804, Chief Justice John Marshall declared that superior orders will justify a subordinate's conduct only "if not to perform a prohibited act", and there are many other early decisions to the same effect. A strikingly illustrative case occurred in the wake of that conflict of which most Englishmen have never heard (although their troops burned the White House) and which we call the War of 1812. Our country was badly split by that war too and, at a time when the United States Navy was not especially popular in New England, the ship-in-the-line Independence was lying in Boston Harbor. A pass-by directed abusive language at a marine standing guard on the ship, and the marine, Bevans by name, ran his bayonet through the man. Charged with murder, Bevans produced evidence that the marines on the Independence had been ordered to bayonet anyone showing them disrespect. The case was tried before Justice Joseph Story, next to Marshall, the leading judicial figure of those years, who charged that any such order as Bevans had invoked " would be illegal and void" , and, if given and put into practice, both the superior and the subordinate would be guilty of murder. In consequence, Bevans was convicted. The order allegedly given to Bevans was pretty drastic, and Boston Harbor was not a battlefield; perhaps it was not too much to expect the marine to realize that literal compliance might lead to bad trouble. But it is only too easy to conceive of circumstances where the matter might not be at all clear. Does the subordinate obey at peril that the order may later be ruled illegal, or is protected unless he has a good reason to doubt its validity?
