Q: Article: Endless playing of songs like All I Want For Christmas in shops during the festive season doesn't just drive us mad--the songs also make us more careless with our money, research has warned. While repeated performance of Jingle Bells may seem like an innocent attempt to raise customers' spirits during the nightmare of Christmas shopping, the songs also have a more delicate impact.[:ZXXK] "Background music, or 'muzak', can be used by marketers to impose cultures--such as the commercialization of Christmas--onto consumers and influence their behaviour, "experts said. Dr. Alan Bradshaw of Royal Holloway, University of London, said, "Festive jingles are force-fed to Christmas shoppers in a bid to change their mood, influence their sense of time and what sort of products they buy. In other words, this is an attempt to control your shopping habits in a way that you might hardly be aware of." "Often we are told that we have the freedom to choose where we want to shop, but during Christmas the use of music in this way is so common that our freedom to choose disappears." Dr. Bradshaw and Prof Morris Holbrook of Columbia University examined the phenomenon and found that retailers often "dumb down" the music played in shops to relax customers, meaning it is easier to control their behaviour. It is thought that slowing down the rhythm of music in shops can trick customers into thinking less time has passed, and therefore spend more time examining the shelves, for example. Some providers of background music have been known to promote their services by claiming they can boost profits by controlling the behaviour of customers. "A common trick is to take a popular current song and record an instrumental version which can be slowed down or sped up at different time of the day to influence behaviour in different ways," Dr Bradshaw said. Background music is often classed as "Muzak" in honor of the Seattle-based company which began producing its soft-sounding melodies in the 1930s.

Q: Article: My heart sank when the man at the immigration counter gestured to the back room. I was born and raised in America, and this was Miami, where I live, but they weren't quite ready to let me in yet. "Please wait in here, Ms. Abujaber," the immigration officer said. My husband, with his very American last name, accompanied me. He was getting used to this. The same thing had happened recently in Canada when I'd flown to Montreal to speak at a book event. That time they held me for 45 minutes. Today we were returning from a literary festival in Jamaica, and I was shocked that I was being sent "in back" once again. The officer behind the counter called me up and said, "Miss, your name looks like the name of someone who's on our wanted list. We're going to have to check you out with Washington." "How long will it take?" "Hard to say...a few minutes," he said, "We'll call you when we're ready for you." After an hour, Washington still hadn't decided anything about me. "Isn't this computerized?" I asked at the counter, "Can't you just look me up?" "Just a few more minutes," they assured me. After an hour and a half, I pulled my cell phone out to call the friends I was supposed to meet that evening. An officer rushed over. "No phones!" he said, "For all we know you could be calling a terrorist cell and giving them information." "I'm just a university professor," I said. My voice came out in a squeak. "Of course you are. And we take people like you out of here in leg irons every day." I put my phone away. My husband and I were getting hungry and tired. Whole families had been brought into the waiting room, and the place was packed with excitable children, exhausted parents, and even a flight attendant. I wanted to scream, to jump on a chair and shout: "I'm an American citizen; a novelist; I probably teach English literature to your children." After two hours in detention , I was approached by one of the officers. "You're free to go," he said. No explanation or apologies. For a moment, neither of us moved. We were still in shock. Then we leaped to our feet. "Oh, one more thing," he handed me a tattered photocopy with an address on it, "If you aren't happy with your treatment, you can write to this agency." "Will they respond?" I asked. "I don't know--I don't know of anyone who's ever written to them before." Then he added," By the way, this will probably keep happening each time you travel internationally." "What can I do to keep it from happening again?" He smiled the empty smile we'd seen all day, "Absolutely nothing." After telling several friends about our ordeal, probably the most frequent advice I've heard in response is to change my name. Twenty years ago, my own graduate school writing professor advised me to write under a pen name so that publishers wouldn't stick me in what he called "the ethnic ghetto"--a separate, secondary shelf in the bookstore. But a name is an integral part of anyone's personal and professional identity--just like the town you're born in and the place where you're raised. Like my father, I'll keep the name, but my airport experience has given me a whole new perspective on what diversity and tolerance are supposed to mean. I had no idea that being an American would ever be this hard.
Answer: her name was similar to a terrorist's

A: The author was held at the airport because _ .

Q: Article: What are feelings for? Most nonscientists will find it a strange question. Feelings justify themselves. Emotions give meaning and depth to life. They exist without serving any other purposes. On the other hand, many evolutionary biologists acknowledge some emotions primarily for their survival function. For both animals and humans, fear motivates the avoidance of danger, love is necessary to care for the young, and anger prepares one to hold ground. But the fact that a behavior functions to serve survival need not mean that. Other scientists have regarded the same behavior as conditioning and learned responses. Certainly reflexes and fixed action patterns can occur without feeling or conscious thought. A baby seagull pecks at a red spot on the bill of its parent. The seagull parent feeds its baby when pecked on the bill and the baby gets fed. The interaction need have no emotional content. At the same time, there is no reason why such actions cannot have emotional content. In mammals that have given birth including humans, milk is often released automatically when a new baby cries. This is not under intended control but it is reflex. Yet this does not mean that feeding a new baby is exclusively reflex and expresses no feeling like love. Humans have feelings about their behavior even if it is conditioned or reflexive. Yet since reflexes exist and conditioned behavior is widespread, measurable, and observable, most scientists try to explain animal behavior by using only these concepts. It is simpler. Preferring to explain behavior in ways that fit science's methods most easily, scientists have refused to consider any causes for animal behavior other than reflexive and conditioned ones. Scientific orthodoxy holds that what cannot be readily measured or tested cannot exist, or is unworthy of serious attention. But emotional explanations for animal behavior need not be impossibly complex or unstable. They are just more difficult for the scientific method to check on in the usual ways, so cleverer and more skillful approaches are called for. Most branches of science are more willing to make successive evaluation of what may prove ultimately unknowable, rather than ignoring it altogether.

A:
