[EX Q]: Article: They already guide blind and disabled people; now dogs are to be trained to help people with dementia or Alzheimer's.Alzheimer's can make people confuse night and day or forget basic things such as washing or drinking enough water. The dogs will be trained to respond to sound triggers in the home that cause them to perform tasks.The duties will include reminding their owners to take medicine, as well as encouraging them to eat, drink and sleep regularly. The idea was developed by design students at the Glasgow School of Art and will now be put into practice by Alzheimer's Scotland and Dogs for the Disabled.The first dogs will be distributed to four Scottish couples, where one of the partners is in the early stages of dementia.Some 670,000 people in Britain have dementia and one in three over 65s will develop the condition.By 2021 this is expected to rise to one million. Joyce Gray of Alzheimer's Scotland said, "People in the early stages of dementia are still able to live a relatively normal life, and dogs help to maintain routine." Another advantage of using the pets as companions is that dogs can give them a sense of silent support and companionship.Ms Gray said, "The evidence is that people may forget familiar faces but not pets.It's such a strong bond that people often remember _ longest.People don't need to communicate verbally but they can still interact.You can have a speechless bond." Helen McCain, director of Dogs for the Disabled, said, "People with dementia often forget to take the medicine.If a dog presents them with a bag with pills in it there's a greater chance of them taking it.The dog would also encourage the owner to take them out for walks, ensuring they keep exercising and interacting with other people."

[EX Q]: Article: prefix = st1 /PITTSBURGH, Sept. 7 -- At 26, many people haven't even decided on a career. Luke Ravenstahl, cashing in on his family's political tradition, is already the mayor of Pittsburgh, the youngest mayor of any major city in the country. Although mayors elsewhere have been younger, Jeff Dunkel was 18 in 2001 when he was elected mayor of Mount Carbon, small towns inNew York, and elsewhere have also elected teenagers as mayors. But,Tallahassee, is the only other city with a population over 100,000 that has had a mayor as young as Mr. Ravenstahl. A supporter of Mr. Ravenstahl said concerns about Mr. Ravenstahl's age would _ once the city saw his work ethic. But now comes the hard part. As he strives to be taken seriously and take charge of a city only recently back from the brink of bankruptcy, the baby-faced mayor said that even the smallest decisions felt weighty, even what to wear in the Steelers game matters. And another pressing issue is to strengthen the city's economy. Pittsburghhas lost all its mills, nearly half its population and much of its downtown commercial district in the last several decades. "ButPittsburghhas 50,000 college students, and our challenge is to figure out how to retain them and to increase downtown development." He said. But one of the biggest uncertainties is how long he will remain in office. According to the city charter, Mayor Ravenstahl's term will not expire until November 2009. Some city lawyers, however, have argued that he must face the electorate next year. And residents in Pittsburghare still withholding judgment on him. Deli, Jimmy Cvetic, a sandwich shop owner, said "I call him Cool Hand Luke. He'll be all right, but he's going to need a cool hand to get through this." Mayor Ravenstahl said he was still coming to terms with the challenge he faced.
