单选题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 ill 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." George Annas, chair of the health law department at Boston University, maintains that, as long as a doctor prescribes a drug for a legitimate medical purpose, the doctor has done nothing illegal even if the patient uses the drug to hasten death. "It's like surgery," he says. "We don't call those deaths homicides because the doctors didn't intend to kill their patients, although they risked their death. If you're a physician, you can risk your patient's suicide as long as you don't intend their suicide." On another level, many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has prolonged the physical agony of dying. Just three weeks before the Court's ruling on physician-assisted suicide, the National Academy of Science (NAS) released a two-volume report, Approaching Death: Improving Care at the End of Life. It identifies the undertreatment of pain and the aggressive use of "ineffectual and forced medical procedures that may prolong and even dishonor the period of dying" as the twin problems of end-of-life care. The profession is taking steps to require young doctors to train in hospices, to test knowledge of aggressive pain management therapies, to develop a Medicare billing code for hospital-based care, and to develop new standards for assessing and treating pain at the end of life. Annas says lawyers can play a key role in insisting that these well-meaning medical initiatives translate into better care. "Large numbers of physicians seem unconcerned with the pain their patients are needlessly and predictably suffering," to the extent that it constitutes "systematic patient abuse." He says medical licensing boards "must make it clear...that painful deaths are presumptively ones that are incompetently managed and should result in license suspension./

单选题 Latino, youths need better education for Arizona to take full advantage of the possibilities their exploding population offers. Arizona's fast-growing Latino population offers the state tremendous promise and a challenge. Even more than the aging of the baby boomers, the Latino boom is fundamentally reorienting the state's economic and social structure. Immigration and natural increase have added 600,000 young Latino residents to the state's population in the past decade. Haft of the population younger than 18 in both Phoenix and Tucson is now Latino. Within 20 years, Latinos will make up half of the homegrown entry-level labor pool in the state's two largest labor markets. What is more, Hispanics are becoming key economic players. Most people don't notice it, but Latinos born in Arizona make up much of their immigrant parents' economic and educational deficits. For example, second-generation Mexican-Americans secure an average of 12 grades of schooling where their parents obtained less than nine. That means they erase 70 percent of their parents' lag behind third-generation non- Hispanic Whites in a single generation. All of this hands the state a golden opportunity. At a time when many states will struggle with labor shortages because of modest population growth, Arizona has a priceless chance to build a populous, hardworking and skilled workforce on which to base future prosperity. The problem is that Arizona and its Latino residents may not be able to seize this opportunity. Far too many of Arizona's Latinos drop out of high school or fail to obtain the basic education needed for more advanced study. As a result, educational deficits are holding back many Latinos—and the state as well. To be sure, construction and low-end service jobs continue to absorb tens of thousands of Latino immigrants with little formal education. But over the long term, most of Arizona's Latino citizens remain ill-prepared to prosper in an increasingly demanding knowledge economy. For the reason, the educational uplift of Arizona's huge Latino population must move to the center of the state's agenda. After all, the education deficits of Arizona's Latino population will severely cramp the fortunes of hardworking people if they go unaddressed and could well undercut the state's ability to compete in the new economy. At the entry level, slower growth rates may create more competition for low-skill jobs, displacing Latinos from a significant means of support. At the higher end, shortages of Latinos educationally ready to move up will make it that much harder for knowledge-based companies staff high-skill positions.
