If you're new to San Francisco, paying the city a visit, or simply looking for a new playground for you and your dog, here are four of the finest dog parks in San Francisco.

    Corona Heights Dog Park

    Often visited by residents from all over the city because of its nearness to the Randall Museum, Corona Heights Dog Park offers pets and owners breathtaking view after a steep hillside climb, and a fenced dog area that allows dogs to let loose without a leash（狗链）. Owners will also enjoy the playground, tennis courts and basketball courts.

    Dolores Dog Park

    The grounds of Dolores Park once served as camps for those who were left homeless by the 1906 earthquake, but now are often visited by crowds of Mission District people. Four-legged friends can also wander about carefree off-leash while making friends with other members of the doggie community.

    Pine Lake Dog Park

    Famous for its place as a rest stop for hundreds of species of birds to fly to and from warmer climates, Pine Lake Park is also prized by city dogs and their owners for their nice hiking paths, picturesque lake suited for swimming, and off-leash area on the park's west end that lets dogs run free.

    Buena Vista Dog Park

    With a history of 146 years, Buena Vista Park is San Francisco's oldest park. Dogs and owners with plus energy will love burning it on this park's steep paths and winding staircases. Dog owners should have good control over their dogs, as it's quite easy for dogs to get separated when going through Buena Vista's many twists and turns.

    Windermere Hotel

    Located in the center of London, our hotel puts guests within easy reach of London's well-known buildings. Buckingham Palace and the Royal Parks are just a short walk away.

    A young woman sits alone in a café sipping tea and reading a book. She pauses briefly to write in a nearby notepad before showing her words to a passing café waiter: "Where are the toilets please?" This is a familiar scene in Tokyo's so-called "silent cafés", where customers are not allowed to speak, and only communicate by writing in notepads.

    The concept rises by a desire to be alone among young Japanese, a situation brought by economic uncertainty, a shift in traditional family support structures and the growing social isolation. The phenomenon is not limited to coffee shops but covers everything from silent discos, where participants dance alone wearing wireless headphones connected to the DJ, to products such as small desk tents designed for conversation-free privacy in the office. One Kyoto company even offers single women the opportunity to have a "one woman wedding"—a full bridal affair, complete with white dress and ceremony, and the only thing missing is the groom. The trend has its own media expression-“botchi-zoku”, referring to individuals who consciously choose to do things completely on their own.

    One recent weekday afternoon, Chihiro Higashikokubaru, a 23-year-old nurse, travelled 90 minutes from her home, to Tokyo on her day off in order to enjoy some solo time. Speaking quietly at the entrance of the cafe, Miss Higashikokubaru said: “I heard about this place via Twitter and I like the idea of coming here. I work as a nurse and it's always very busy. There are very few quiet places in Tokyo, and it's a big busy city. I just want to come and sit somewhere quietly on my own. I'm going to drink a cup of tea and maybe do some drawings. I like the idea of a quiet, calm atmosphere.”

    The desire to be isolated is not a new concept in Japan, home to an estimated 3.6 million "hikikomori" - a more extreme example of social recluses(隐士) who withdraw completely from society.

    No one likes to make mistakes. But a new study says organizations learn more from their failures than from their successes, and keep that knowledge longer.

    One of the researchers was Vinit Desai, an assistant professor at the University of Colorado Denver Business School. He worked with Peter Madsen from the Marriott School of Management at Brigham Young University in Utah.

    They did not find much long-term "organizational learning" from success. It is possible, they say. But Professor Desai says they found that knowledge gained from failure lasts for years. He says organizations should treat failures as a learning opportunity and not try to ignore them.

    The study looked at companies and organizations that launch satellites and other space vehicles. Professor Desai compared two shuttle flights. In two thousand two, a piece of insulating (隔热的) material broke off during launch and damaged a rocket on the Atlantis. Still the flight was considered a success. Then in early two thousand three, a piece of insulation struck the Columbia during launch. This time, the shuttle broke apart on re-entry and the seven crew members died. NASA officials suspended all flights and an investigation led to suggested changes.

    Professor Desai says the search for solutions after a failure can make leaders more open-minded. He points to air-lines as an example of an industry that has learned from failures in the past. He advises organizations to look for useful information in small failures and failures they avoided. He also urges leaders to encourage the open sharing of information. The study appeared in the Academy of management Journal.

    The mistakes we learn from do not have to be our own. We recently asked people on our Facebook page to tell us a time they had done something really silly. Fabricio Cmino wrote: Not long ago I wanted to watch TV, but it wouldn't turn on, so I did everything I could to start it. Thirty minutes later my mum showed up and, passing by, said to me "Did you try plugging it?" "I'm just dusting, Mum!" So she wouldn't notice how dumb I am sometimes!

    Bruno Kanieski da Silva told about a time he looked everywhere for his key. It was in his pocket. He wrote: I always promise I will never do it again, but after a few weeks, where is my wallet? For sure it will be in a very logical place.

    The Lantern Festival falls on the 15th of the first month of the lunar calendar. This day is always the first full moon in the new year. Ancient people also called it Shangyuan Festival. Celebrations and traditions on this day began from the Han Dynasty and became popular in the Tang Dynasty.

    Watching the red lanterns is one of the main traditions. Lanterns of different shapes and sizes are usually put on trees, or along river banks on show. It is said that sky lanterns were first used by Zhuge Kongming to ask for help when he was in trouble. Today, when the lanterns slowly rise into the air, people make wishes. Another tradition is guessing lantern riddles. The riddles are usually short, wise, and sometimes humorous. The answer to a riddle can be a Chinese character, a famous person's name, or a place name.

    The most important thing is to eat sweet dumplings with different tastes. In northern China, they are called yuanxiao while in southern part they're named tangyuan. Because making sweet dumplings is like a game or an activity, they are usually done happily by a group of friends or family members.

    In old times, the Lantern Festival was also a good time for young people to find love. Watching lanterns gave young people a chance to meet each other. And there were many romantic stories about this festival. A line from Xin Qiji, a poet during the Song Dynasty, shows this, "Hundreds and thousands of times I searched for her in the crowd. Suddenly I turned, and there she stood in the dim light. "

    In a word, the Lantern Festival has brought us Chinese so much fun and joy over the years. We hope the young people can carry on these traditions and take pride in Chinese culture.
