单选题 Crippling health care bills, long emergency-room waits and the inability to find a primary care physician just scratch the surface of the problems that patients face daily. Primary care should be the backbone of any health care system. Countries with appropriate primary care resources score highly when it comes to health outcomes and cost. The US takes the opposite approach by emphasizing the specialist rather than the primary care physician. A recent study analyzed the providers who treat Medicare beneficiaries.The startling finding was that the average Medicare patient saw a total of seven doctors—two primary care physicians and five specialists—in given one year. Contrary to a popular belief, the more physicians taking care of you doesn't guarantee better care. Actually, increasing fragmentation of care results in a corresponding rise in cost and medical errors. How did we let primary care slip so far? The key is how doctors are paid. Most physicians are paid whenever they perform a medical service. The more a physician does, regardless of quality or outcome, the better he's reimbursed. Moreover, the amount a physician receive leans heavily toward medical or surgical procedures. A specialist who performs a procedure in a 30-minute visit can be paid three times more than a primary care physician using that same 30 minutes to discuss a patient's disease.Combine this fact with annual government threats to indiscriminately cut reimbursements, physicians are faced with no choice but to increase quantity to boost income. Primary care physicians who refuse to compromise quality are either driven out of business or to each-only practices, further contributing to the decline of primary care. Medical students aren't blind to this scenario. They see how heavily the reimbursement deck is stacked against primary care. How do we fix this problem? It starts with reforming the physician reimbursement system. Remove the pressure for primary care physicians to squeeze in more patients per hour, and reward them for optimally managing their diseases and practicing evidence based medicine. Make primary care more attractive to medical students by forgiving student loans for those who choose primary care as a career and reconciling the marked difference between specialist and primary care physician salaries.

单选题"Popular art" has a number of meanings, impossible to define with any precision, which range from folklore to junk. The poles are clear enough, but the middle tends to blur. The Hollywood Western of the 1930" s, for example, has elements of folklore", but is closer to junk than to high art or folk art. There can be great trash, just as there is bad high art. The musicals of George Gershwin are great popular art, never aspiring to high art. Schubert and Brahms, however, used elements of popular music—folk themes—in works clearly intended as high art. The case of Verdi is a different one: he took a popular genre—bourgeois melodrama set to music ( an accurate definition of nineteenth-century opera)—and, without altering its fundamental nature, transmuted it into high art. This remains one of the greatest achievements in music, and one that cannot be fully appreciated without recognizing the essential trashiness of the genre. As an example of such a transmutation, consider what Verdi made of the typical political elements of nineteenth-century opera. Generally in the plots of these operas, a hero or heroine—usually portrayed only as an individual, unfettered by class—is caught between the immoral corruption of the aristocracy and the doctrinaire rigidity or secret greed of the leaders of the proletariat. Verdi transforms this naive and unlikely formulation with music of extraordinary energy and rhythmic vitality , music more subtle than it seems at first hearing. There are scenes and arias that still sound like calls to arms and were clearly understood as such when they were first performed. Such pieces lend an immediacy to the otherwise veiled political message of these operas and call up feelings beyond those of the opera itself. Or consider Verdi"s treatment of character. Before Verdi, there were rarely any characters at all in musical drama, only a series of situations which allowed the singers to express a series of emotional states. Any attempt to find coherent psychological portrayal in these operas is misplaced ingenuity. The only coherence was the singer"s vocal technique: when the cast changed, new arias were almost always substituted, generally adapted from other operas. Verdi"s characters, on the other hand, have genuine consistency and integrity, even if, in many cases, the consistency is that of pasteboard melodrama. The integrity of the character is achieved through the music: once he had become established, Verdi did not rewrite his music for different singers or countenance alterations or substitutions of somebody else"s arias in one of his operas, as every eighteenth-century composer had done. When he revised an opera, it was only for dramatic economy and effectiveness.
