    There are a lot of reasons why people calling 911 might not be able to tell operators which floor they're on in a high-rise building. They could be injured or simply confused. Yet precious minutes are wasted when emergency personnel have to search a building to find a person in need. With a new app called Sensory, emergency responders soon may be able to use a caller's smartphone to locate his exact position in a building.

    Columbia University researchers William Falcon and Henning Schulzrinne created Sensory using a two-step process. First, they used all existing smartphone features that help narrow down a caller's location. All iPhones produced after 2014 already include GPS and altimeter（测高仪） that can help emergency responders determine if a person is outdoors or inside a building. But when it comes to tall buildings, just knowing a person's altitude may not be enough，because the distance between floors changes from one building to another.

    So Falcon and Schulzrinne analysed the plans of figuring out the average distance between floors in residential（住宅的）buildings and office buildings among more than 1000 buildings in New York City. They tested their app in 63 experiments in five high-rise buildings and found that it could find a caller's location within two floors with about a 91 percent accuracy.

    In a survey conducted by Find Me 911 this year, dispatchers（调度员）said that they regularly received calls from people in need who often couldn't share their location. They sometimes accidentally give the wrong address or floor number. Some callers are too young to know their address. Dispatchers also received calls from those who are deaf or have hearing problems and they often couldn't hear the operator's questions.

    The new Sensory app could help shave precious minutes off the time it takes first responders to get to those calling for help. And it could make the difference between life and death.

    According to a new US study, couples who expect their children to help care for them in old age should hope they have daughters because they are likely to be twice as attentive overall.

    The research by Angelina Grigoryeva, a sociologist at Princeton University, found that, while women provide as much care for their elderly parents as they can manage, men do as little as they can get away with and often leave it to female family members.Her analysis of the family networks of 26,000 older Americans concluded that gender(性别) is the most important predictor(预示物) of whether or not people will actively care for elderly parents.

    In a paper being presented at the annual conference of the American Sociological Association in San Francisco, she concludes that simply having a sister makes men statistically likely provide less care.

    Using data from the University of Michigan Health and Retirement Study, a study which has been tracking a cross-section of over-50s for the last decade, she calculated that women provide an average of 12.3 hours a month of care for elderly parents while men offer only 5.6 hours.

    “Whereas the amount of elderly parent care daughters provide is associated with limitations they face, such as employment or childcare, sons' caregiving is associated only with the presence or absence of other helpers, such as sisters or a parent's spouse(配偶),” she explained.

    “Sons reduce their relative caregiving efforts when they have a sister, while daughters increase theirs when they have a brother.”

    “This suggests that sons pass on parent caregiving responsibilities to their sisters.”

    In the UK, the 2011 census(人口普查) showed that there are now around 6.5 million people with caring responsibilities – a figure which has risen by a tenth in a decade.

    But many are doing so at the risk of their own health. The census showed that those who provide 50 hours or more of care a week while trying to hold down a full- time job are three times more likely to be struggling with ill health than their working counterparts(相对应的人) who are not carers.

    When I was 8 years old, I decided to run away from home after a quarrel with my mother. With my suitcase(行李箱) packed and some sandwiches in a bag, I started for the front door.

    My mom asked where I was going. “I'm leaving home,” I said.

    “What's that you're carrying?” she asked.

    “Some clothes and food,” I replied.

    “If you want to run away, that's all right,” she said. “But you came into this home without anything and you can leave the same way.”

    I threw my suitcase and sandwiches on the floor and started for the door again.

    “Wait a minute,” Mom said. “You didn't have any clothes on when you arrived, and I want them back.”

    This infuriated me. I tore my clothes off — shoes, socks, underwear and all — and shouted, “Can I go now?”

    “Yes,” my mom answered, “but once you close that door, don't expect to come back.”

    I was so angry that I shut the door forcefully and stepped out of my home. Then I noticed down the street two neighbor girls walking toward our house. I was so shy that I saw the big spruce (云杉) tree in our yard and jumped under the low-hanging branches (树枝). A pile of dried-up brown needles (针状物) were beneath the tree, and you can't imagine the pain those sharp needles caused to my body.

    After I was sure the girls had passed by, I ran to the front door and knocked at it loudly.

    “It's Billy! Let me in!”

    The voice behind the door answered, “Billy doesn't live here anymore. He ran away from home.”

    Looking behind me to see if anyone else was coming down the street, I said, “Mom! I'm sorry. I'm still your son. Let me in!”

    The door opened and Mom's smiling face appeared. “Did you change your mind about running away?” she asked.

    “What's for supper?” I smiled back.

    About six years ago I was eating lunch in a restaurant in New York City when a woman and a young boy sat down at the next table. I couldn't help overhearing parts of their conversation. At one point the woman asked, "So, how have you been?" And the boy — who could not have been more than 7 or 8 years old —replied, "Frankly, I've been feeling a little depressed lately."

    This incident(小事件) stuck in my mind because it confirmed(证实) my growing belief that children are changing. As far as I can remember, my friends and I didn't find out we were "depressed" until we were in high school.

    The evidence of a change in children has increased steadily in recent years. Children don't seem childlike anymore. Children speak more like adults, dress more like adults and behave more like adults than they used to. Whether this is good or bad is difficult to say, but it is certainly different. Children as they once were on longer exists. Why?

    Human development is based not only on innate biological states, but also on patterns of access to social knowledge. Movement from one social route to another usually involves learning the secrets of the new status. Children have always been taught adult secrets, but slowly and in stages: traditionally, we tell sixth graders things we keep hidden from fifth graders.

    In the last 30 years, however, a secret-revelation (揭示)machine has been installed in 98 percent of American homes. It is called television. Television passes information indiscriminately to all viewers alike, be they children or adults. Unable to resist the temptation, many children turn their attention from printed texts to the less challenging, more vivid moving pictures.

    Communication through print, as a matter of fact, allows for a great deal of control over the social information to which children have access. Reading and writing involve a complex code of symbols that must be memorized and practiced. Children must read simple books before they can read complex materials.
