Article: Amazingly, US crime figures have been falling for 20 years now. Of course, the big question is, why? And can any lessons be learnt? One reason could be the fall in the demand for the drug crack. During the 1980s, drug-related crimes soared, mostly caused by desperate crack users. However, according to professor Blumstein, co-author of The Crime Drop in America, news of the dangers of crack use caused its decrease and led to a fall in the number of drug-related crimes. Some say that the adoption of a zero-tolerance policy in many cities has helped lead to a fall in crime. In New York City, for example, mayor Rudy Giuliani imposed strict and automatic punishments for all crimes, including minor offences such as graffiti and littering. Many believe this has had a very strong deterrent effect. Another reason could be smarter policing strategies. Anti-theft measures and educating the community about car theft has helped see a drop in crimes in many areas. Also, the use of crime mapping schemes that can discover identify crime peaks in different parts of the city has helped police target hotspots. Another reason could be that more criminals are now behind bars. Sociologist John Conklin (from Tufts University) says a significant factor behind the fall in crime in the 1990s is the simple fact that many criminals are in jail. In his book Why Crime Rages Fell, he says sentencing was merciful in the 1960s and 1970s, when crime rose. But then more prisons were built and more offenders were imprisoned. Some have linked the fall in violent crime to a decline in children's exposure to lead in petrol. Jessica Wolpaw Reyes says, "Even low to moderate levels of exposure can lead to behavioral problems, reduced IQ, hyperactivity and youth crimes. You can link the decline in lead between 1975 and 1985 to a decline in violent crime 20 years later." Others say that the drop in crime has something to do with birth rates. According to statistics, birth rates peaked between 1957 and 1961, and the proportion of men in the US in their late teens and early 20s (the so-called "criminal age") was highest in the late 70s and early 80s. However, as time went on, the proportion of people in this age group decreased. Others claim that videogames have helped. A recent study has suggested that these games are keeping young people off the streets and therefore away from crime. Advocates of this argue that any effects the games may have in encouraging violent behavior is _ by the fact that the games keep potential criminals indoors and in front of the television. Some argue that the widespread use of camera phones makes some criminals think twice before committing a crime and getting filmed doing it. Also, many believe that the mass use of CCTV has also had an effect. Finally, some say that petty theft just isn't worth it any more. The resale value of second-hand goods such as televisions, cameras or clothes is now so low (or even non-existent) that most people see no point in stealing. So, what do you think?

Article: The nervous-looking young man had waited for a few moments--outside the jeweler's before he got enough courage to enter. He was warmly greeted by a young assistant. James felt a rush of blood to his face as he explained he would be bringing in his future wife to choose a birthday present. The assistant listened carefully and told him he'd better buy a necklace. He wasn't used to buying jewellery and was a little worried about over-spending. After some discussion as to a reasonable price and the type, the assistant showed him dozens of necklaces and helped him to choose. At last James chose one and left the shop promising to return at five o'clock. When, half an hour later than planned, James did return to the shop with his future wife, Laura, the assistant acted as if she had never seen him before. When she was asked to show them some necklaces, she first brought out some inexpensive ones for them to choose, and then gave them the one she had prepared. A choice was soon made and they went away satisfied. James would certainly come back to buy what he wanted.

Article: Although travelers can try dishes from around China and the globe in well-known food cities like Beijing and Shanghai, it is outside these major metropolises where a world of exciting Chinese cuisine awaits the true foodie . With this in mind and after three years of living in China and writing about Chinese food, I started a six-month journey with my husband and two daughters. Here are four of the eight most amazing Chinese food cities I've come across so far. The list is in no particular order. 1. Chengdu, Sichuan Province Crowned as Asia's first UNESCO City of Gastronomy in 2010, Chengdu is best-known for its fiery hot pot and spicy dishes, which are characterized by the use of Sichuan pepper and are usually layered with salty, sour and sweet flavors. There are also dishes that aren't spicy at all, such as beer-braised duck. Hot pot is as _ in the city as the smell of chili. At Zigong Delicious Hotpot, the house specialty tiaoshui wa is a cauldron of fiery chili to which vegetables, noodles or other meats can be added. For a real taste of Sichuan's signature pepper, hua jiao, spend a morning at the Chengdu Spice Market where the locals sell and buy it by the sack. 2. Lanzhou, Gansu Province Synonymous in the minds of food-lovers with hand-pulled beef noodles, Lanzhou also has one of the liveliest street food night markets in China. Just west of the city center, the buzzing Zhengning Road bazaar houses more than 100 street food stalls. Available is a broad selection of hot and cold dishes with emphasis on local Hui cuisine. No trip to Lanzhou is complete without feasting on noodles at Wumule Penhui, the 2012 winners of Lanzhou's annual pulled noodle competition. The halal restaurant makes noodles spicy enough to satisfy even the most hardened heat-seekers. 3. Guangzhou, Guangdong Province The birthplace of Cantonese food, Guangzhou is thought by many as the best place to eat in China. The city of 12 million has a passionate food culture, with equal excitement reserved for the opening of a hole-in-the-wall congee joint and a high-end restaurant. The local cuisine is characterized by fresh clean flavors , seafood, barbecued meats and the wonderful tradition of yum cha, which is tea drinking accompanied by dumplings and small dishes. Congee is the way locals love to start their day, and one of the most popular vendors is Ru Xuan Sha Guo Zhou. Here, one can get a bowl of signature seafood congee any hour of the day. Roast meats are Bing Sheng's most popular order--their roast goose is marinated with five-spice, boiled, air-dried, then roasted by a flame oven to give a crisp skin. For something more home style and removed from the madness of downtown, head to Ji Cun for steamed chicken and simple farmer-style dishes. 4. Shaoxing, Zhejiang Province This ancient canal city is home to huangjiu, an amber-colored rice wine that's important in Chinese cooking. Open since 1894, the dining chain is known by almost every Chinese for its appearance in early 20th century novels by Chinese literati Lu Xun. Xianheng's delicacies include crispy-skinned chicken, smoked red dates in rice wine, beans flavored with fennel , and crispy bream in rice wine. Fried fermented tofu is also a local specialty, which is available all over town at small street stalls including one just outside Xianheng.
