[EX Q]: Article: Since 1984, Philadelphia has been cleaning up its act. One by one, graffiti-covered walls are being changed into outdoor art. So far, more than 1,800 murals have been painted. Philadelphia now has more murals than any other American city. The walls that were once ugly with graffiti are now covered with beautiful pictures of historical heroes and modern art, thanks to the Mural Arts Program (MAP). Its work makes schools and public places attractive, and its citizens very proud. The program began as part of Philadelphia's Anti-Graffiti Network. Jane Golden is the MAP's artistic director. "When people ask me what our program is about," she says, "I answer them with one word: hope." Each year, the MAP offers youth art programs and workshops. Some one-time graffiti writers even help paint MAP murals. The MAP's work, says Golden, is all about developing a sense of community . When a neighborhood requests a mural, the MAP works with the people there to develop a message. Some messages have been "Safe Streets," "Love and Care," and "Peace Walk." The MAP receives up to 50 requests for murals each week. Last year, the workers painted 140 murals. "The making of a mural enters people's collective memory as an extraordinary, pleasant moment in neighborhood history" says Golden, who began as a muralist in Los Angeles.

[EX Q]: 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?

[EX Q]: Article: Australian scientists say an organic compound used by Indian women to paint dots or bindi on their foreheads could hold the key to a breakthrough in cancer treatment. Rose Bengal was first used in the early 1900s as a dye for food, textiles and cosmetics. But now it is proving to be a useful weapon in the fight against skin cancer. Television advertisements constantly warn of the dangers of overexposure to the fierce sun. Among them is the possibility of the disease melanoma , a type of skin cancer. More than 1,200 Australians die every year from the disease. Initial trials of a solution of Rose Bengal injected into some melanoma cells have had a 75 percent success rate in controlling the disease. Professor John Thompson, the director of the Melanoma Unit at the University of Sydney, says this organic dye could become a powerful cancer-fighting treatment. "We believe it works by getting into the tumor cells and causing them to self-destruct. But the exact mechanism by which it works is not totally clear. It's not useful for people who have a primary melanoma. The treatment of primary melanoma is surgical excision ,"he said. "It's useful to inject tumors for people who have recurrences; when the primary treatment has failed and when recurrence in the area, or at more distant sites has occurred." About 90 percent of Australians who develop melanoma survive thanks to early diagnosis and treatment. If left untreated, however, the disease can be fatal. Convincing younger people in Australia about the dangers of overexposure to the sun is a battle campaigners are constantly waging. Veronica Manock, a 21-year-old student, had two major operations to remove a cancerous tumor from her leg. "I've had a lot of friends who just said 'I thought it was just, you know, I'll get a mole cut out and that's it', whereas I don't think people realize how much danger they're putting themselves into and how easy it is to stop something like this happening to you just from doing little things,"said Marock. Other researchers in Australia are investigating genetic treatments to skin cancer. There is a pressing need for such research to produce effective treatments. Australians, the majority of whom are fair-skinned , are four times more likely to develop a melanoma than people in Canada, the United States or Great Britain.
