单选题 Clothes play a critical part in the conclusions we reach by providing clues to who people are, who they are not, and who they would like to be. They tell us a good deal about the wearer's background, personality, status, mood, and social outlook. Since clothes are such an important source of social information, we can use them to manipulate people's impression of us. Our appearance assumes particular significance in the initial phases of interaction that is likely to occur. An elderly middle class man or woman may be alienated by a young adult who is dressed in an unconventional manner, regardless of the person's education, background, or interests. People tend to agree on what certain types of clothes mean. Adolescent girls can easily agree on the lifestyles of girls who wear certain outfits, including the number of boyfriends they likely have had and whether they smoke or drink. Newscasters, or the announcers who read the news on TV, are considered to be more convincing, honest, and competent when they are dressed conservatively. And college students who view themselves as taking an active role in their interpersonal relationships say they are concerned about the costumes they must wear to play these roles successfully. Moreover, many of us can relate instances in which the clothing we wore changed the way we felt about ourselves and how we acted. Perhaps you have used clothing to gain confidence when you anticipated a stressful situation, such as a job interview, or a court appearance. In the workplace, men have long had well defined precedents and role models for achieving success. It has been otherwise for women. A good many women in the business world are uncertain about the appropriate mixture of "masculine" and "feminine" attributes they should convey by their professional clothing. The variety of clothing alternatives to women has also been greater than that avail able for men. Male administrators tend to judge women more favorably for managerial positions when the women display less "feminine" grooming—shorter hair, moderate use of make up, and plain tailored clothing. As one male administrator confessed, "An attractive woman is definitely going to get a longer interview, but she won't get a job."

单选题As the Tailhook sexual-assault scandal drove him into early retirement from the Navy, Admiral Frank Kelso last week sought to overhaul his image. The Navy's top officer claimed that during his nearly four years at the helm, he had helped rid the service of its tolerance for abusive attitudes toward women. If anyone treats women as did the drunken, groping aviators at the Tailhook convention two and half years ago, Kelso blustered at a press conference, "they're not going to be in this man's Navy." In fact, his legacy is a Navy still straining to accommodate women, homosexuals and members of racial minorities. At the same time, the Navy's reputation has been battered by the investigations into Tailhook and cheating by midshipmen at the Naval Academy in Annapolis. Some naval officers and military experts note that the Navy's recent problems have come under a series of chiefs — from James Watkins in 1982 to Carlisle Trost in 1986 to Kelso — who arose from the aloof and secretive submarine fleet. Submarine commanders usually are trained as engineers and are not renowned for their people skills. Presiding over crews of 155 or fewer highly screened men hasn't prepared the Navy's recent leaders to grapple with modern personnel problems. Kelso and other submariners "didn't have the leadership challenges that surface-warfare officers had," agrees Senator John McCain of Arizona, a retired Navy pilot. The Navy hasn't been run by a purebred surface-ship captain — whose sailors make up the bulk of its force — since Elmo Zumwalt left the job a generation ago. "When you go a long period of time without having a surface- fleet CNO (Chief of Naval Operations), then it becomes a very serious morale problem for that vast segment of the Navy," Zumwalt says. Early speculation was that President Clinton would name Admiral Jeremy ("Mike") Boorda, a surface-warfare officer, as CNO. Unlike all 24 CNOs who came before, Boorda, a high school dropout, never attended the Naval Academy. As the Navy personnel chief from 1988 to 1991, he drafted a plan that allowed the Navy, unlike other services, to shrink dramatically without firing personnel. But an Administration official said Saturday that Clinton might prefer to keep Boorda in his sensitive Naples post, where he has been planning the possible NATO bombing campaign against the Serbs. If so, the next CNO is likely to be Admiral Charles Larson, the Pentagon's Pacific commander — a Naval Academy graduate who would be the fourth submariner in a row to run the Navy.

单选题 The big identity-theft bust last week was just a taste of what's to come. Here's how to protect your good name. HERE'S THE SCARY THING about the identity-theft ring that the Feds cracked last week: there was nothing any of its estimated 40000 victims could have done to prevent it from happening. This was an inside job, according to court documents. A lowly help-desk worker at Teledata Communications, a software firm that helps banks access credit reports online, allegedly stole passwords for those reports and sold them to a group of 20 thieves at $60 a pop. That allowed the gang to cherry-pick consumers with good credit and apply for all kinds of accounts in their names. Cost to the victims: $3 million and rising. Even scarier is that this, the largest identity-theft bust to date, is just a drop in the bit bucket. More than 700000 Americans have their credit hijacked every year. It's one of crime's biggest growth markets. A name, address and Social Security number—which can often be found on the Web—is all anybody needs to apply for a bogus line of credit. Credit companies make $1.3 trillion annually and lose less than 2% of that revenue to fraud, so there's little financial incentive for them to make the application process more secure. As it stands now, it's up to you to protect your identity. The good news is that there are plenty of steps you can take. Most credit thieves are opportunists, not well-organized gangs. A lot of them go Dumpster diving for those millions of "pre-approved" credit-card mailings that go out every day. Others steal wallets and return them, taking only a Social Security number. Shredding your junk mail and leaving your Social Security card at home can save a lot of agony later. But the most effective way to keep your identity clean is to check your credit reports once or twice a year. There are three major credit-report outfits: Equifax (at equifax. com), Trans-Union (www. transunion. come) and Experian (experian. com). All allow you to order reports online, which is a lot better than wading through voice-mail hell on their 800 lines. Of the three, I found Trans-Union's website to be the cheapest and most comprehensive—laying out state-by-state prices, rights and tips for consumers in easy-to-read fashion. If you're lucky enough to live in Colorado, Georgia, Maryland, Massachusetts, New Jersey or Vermont, you are entitled to one free report a year by law. Otherwise it's going to cost $ 8 to $14 each time. Avoid services that offer to monitor your reports year-round for about $70; that's $10 more than the going rate among thieves. If you think you're a victim of identity theft, you can ask for fraud alerts to be put on file at each of the three credit-report companies. You can also download a theft-report form at www. consumer. gov/idtheft, which, along with a local police re- port, should help when irate creditors come knocking. Just don't expect justice. That audacious help-desk worker was one of the fewer than 2% of identity thieves who are ever caught.
