Located in Los Angeles, University of Southern California is in the heart of a leading city. Although LA ranks highly in The Economist s Safe Cities Index, navigating and city calls for certain safety precautions (预防措施) along with practicing common sense.

    Mobile Safety App Powered by LiveSafe

    The Mobile Safety App powered by LiveSafe, manage by the USC Department of Public Safety and the USC Department of Emergency Planning, is a free downloadable app that that mobile users can use to initiate contact with emergency responders around the campus. Features include: immediate “push button” calls to DPS, easy reporting for suspicious activity or crimes in progress, and location services to notify friends of your route through campus.

    Blue Light Phone Locations

    The University Park has multiple blue light phones that are strategically placed throughout campus. Take note of where the closest ones are on your route. They come in handy in case you lose your phone or in an emergency. These phones are directly connected to USC's Department of Public Safety's 24-hour communications center. Besides emergency needs, it can also be used to report suspicious activity, request for an escort (护送) if you feel unsafe and to report a crime.

    Trojans Alert

    Trojans Alert is an emergency notification system that allows university officials to contact you during an emergency by sending messages via text message or email. When an emergency occurs, authorized USC senders will instantly notify you with real-time updates, instructions on where to go, what to do (or what not to do), whom to contact and other important information.

    Six years ago at the age of 35,I suddenly decided I wanted to learn the cello（大提琴）.Straight away I rented an instrument and appeared before Wendell Margrave,professor of musical instruction.

    "You can be as good as you want to be,"Margrave said rather mysteriously.On a piece of paper he drew the notes E and F.He showed me where to put my fingers on the neck of the cello and how to draw the bow.Then he entered my name in his book: 10 am,Tuesday.Tuesday followed Tuesday,and soon it was spring.

     Thus began my voyage out of ignorance and into the dream.E-F,E-F,we played together—and moved on to G.It was a happy time.I was again becoming something new,and no longer trapped as the same person.Surely the most terrible recognition of middle life is that we are past changing.We do what we can already do.The cello was something I couldn't do.Yet each Tuesday this became less and less true.Riding home on the bus one snowy night and learning the score of Mozart's C-Major Quintet(莫扎特的C大调五重奏),I felt the page burst into music in my hands.I could by then more or less read a score,and was humming（哼唱）the cello line,when suddenly all five parts came together harmonically（和谐地） in my head.The fellow sitting opposite stared.I met his glance with tears,actually hearing the music in my head for the first time.Could he hear it too, perhaps?No,he got off at the next stop.

    As the years slipped by,my daughter grew up,playing the piano well.My goal was that she and I would one day perform together.I also wanted to perform in public with and for my peers,and to be secretly envied.I continued to play,to perform,but it is not the same. Before, when I heard a cello,it was all beauty and light.Now,as the TV camera gets close to Rostropovich's face,I recognize that his smile shows his incredible determination.Even for him,the cello is a difficult instrument that doesn't respect your ambitions.I picked up my cello and practiced.As good as I wanted to be,I am as good as I'm going to get.It is good enough.

    Jack threw the papers on my desk. “Next time you want to change anything, ask me first,” he said. I had changed a long sentence and corrected its grammar — something I thought I was paid to do.

    Several days later, he made me angry again. I went to his office, prepared to lose my job if need be, but not before I let the man know how I felt. “What?” he said nervously.

    Suddenly I knew what I had to do. “Jack, the way you've been treating me is wrong. And it's wrong for me to allow it to continue,” I said. “I want to make you a promise. I will be a friend.” The next day I brought some cakes to Jack's office. Every time I saw Jack in the hall, I smiled at him. After all, that's what friends do.

    One year after our talk, I was told that I had breast cancer . When I was in hospital, my friends tried to find the right words to say, but no one could. The last day of my hospital stay, the door opened and Jack walked over to my bed. “Tulips (郁金香),” he placed some bulbs  beside me and said, “If you plant them when you get home, you'll be there to see them when they come up.” Tears filled my eyes.

    In a moment when I prayed for just the right words, a man with few words said the right thing. After all, that's what friends do. Now, I have seen those tulips push through the soil every spring for over ten years.

    Contrary to popular belief, people who sleep six to seven hours a night live longer, and those who sleep eight hours or more die younger, according to the latest study ever conducted on the subject. The study, which has tracked the sleeping habits of 1.1 million Americans for six years, weakens the advice of many sleep doctors who have long recommended that people get eight or nine hours of sleep every night.

    “There's an old idea that people should sleep eight hours a night, which has no more scientific basis than the gold at the end of the rainbow,” said Daniel Kripke, professor of psychiatry（精神病学）at the University of California at San Diego who led the study published in a recent copy of JAMA Psychiatry.

    The study was not designed to answer why sleeping longer may be harmful or whether people could extend their lifespan by sleeping less.

    But Kripke said it was possible that people who slept longer tended to suffer from short-term absence of sleeping, a condition where weak breathing puts stress on the heart and brain. He also stressed that the need for sleep was similar to that for food, where getting less than people want may be better for them.

    The study quickly caused warnings and criticism（批评）, with some sleep experts saying that the main problem of America's sleep habits was deprivation（剥夺）, not sleeping too much.

    “None of this says sleep kills people,” said Daniel Buysse, a psychiatrist at the university of Pittsburgh Medical Center.

    “You should sleep as much as you need to feel awake, alert and attentive the next day,” Buysse added. “I'm much more concerned about people short-changing themselves on sleep than people sleeping too long.”

    “Sleeplessness produces a variety of health consequences that were not measured in the study,” critics said.

    Never before have Chinese Internet users so openly liked and supported a Japanese athlete as they have loved table tennis star Ai Fukuhara (福原爱), better known by her Japanese nickname “Ai-Chan”.

    But they may now feel heartbroken, as the 29-year-old said on Oct.21 that she would retire (退役) from the sport. I've found the answers within myself that I have been searching for. From the standpoint ( 立场) of an athlete, I'm drawing the line here," Fukuhara wrote on her blog.

    After she started playing table tennis at 3 years old, Fukuhara was seen as a child gifted at the sport. Being trained in China at a very young age, Fukuhara can speak fluent Mandarin, with a northeastern accent.

    If her deep-rooted connection with China is one thing that has won the hearts of Chinese fans, her character is another. She always shows her real self to the public without hiding her feelings. She laughs in games when she wins, and cries when she loses. The fact that she often cries when she gets upset has earned her the nickname “Crybaby Ai-Chan” in China.

    Although she was beaten by a long line of Chinese players, Fukuhara always tries her best when playing her favorite sport. Yet, she also knows that now is the best time to close the curtain on her successful career. It's hard to say goodbye to a long journey but as Fukuhara once said on a reality TV show, “Life is not all about table tennis. Instead, it is just part of life.”

    As for her future plans, Fukuhara wrote that she would like to help more people around the world get to know the beauty of the sport.

    A lifetime of active exercise will let you keep the body of a 20-year-old well into your 70s, scientists have found.

    The physical decline (衰退) thought to be an unavoidable part of ageing is actually the result of not exercising enough, according to the research, which found that regular cyclists kept the muscles, lungs, and even the immune system (免疫系统) of people years younger. Besides, many serious health problems could be prevented if people became more active, researchers insist.

    Janet Lord, a leading researcher, said, “Our findings prove the false belief that ageing automatically makes us weaker. We now have strong evidence that encouraging people to do regular exercise throughout their lives can solve the problem that we are living longer but not healthier.”

    She looked at 125 cyclists aged 55 to 79 who had been exercising regularly for 25 years and compared them with 75 ordinary people of a similar age and 55 people aged 20 to 36. On a series of physical measures, the cyclists showed no difference from people much younger in their immune systems and making T cells.

    Now Professor Lord aims to discover how much exercise people need to do to stay young. “You needn't work out a lot. It may be intensity (强度) that helps—like going up and down the stairs ten times a day.”

    While there is no magic method of staying mentally and physically fit in later life, the benefits of keeping active can never be ignored, whatever your age or state of health.
