It isn't often that zookeepers call on craftsman for help. But cold weather at the Wildlife SOS Elephant Conservation and Care Center in northern India was putting elephants at risk. So the center's staff joined forces with locals to find a creative way to keep the animals warm. Now the elephants are stepping out in style, thanks to volunteers who made use of their crafting talents to knit (编织) enormous sweaters to protect the animals.

    Wildlife SOS is a conservation group that has been taking action against animal cruelty and saving wildlife in danger since 1995. Their Elephant Conservation and Care Center is devoted to rescuing the large animals from abuse in circuses, illegal dealing, and other circumstances where they have been ignored or treated with extreme cruelty. There are currently 20 elephants living at the center, and the staff hope to take in 50 more of the creatures this year.

    Because most of the elephants housed at the center are recovering from injuries or are elderly and weak, they are particularly vulnerable to cold temperatures. When the staff reported near-freezing nighttime temperatures in the winter, volunteers from surrounding villages began knitting enormous sweaters to keep the elephants warm. The monumental sweaters are large enough to cover the elephants' backs, bellies, and legs.

    Making the sweaters is a big undertaking—each one takes approximately four weeks to create, with volunteers working together on the enormous clothes. Local villagers have already made sweaters for three of the 23 elephants on their own, each with a unique pattern and color.

    If you're also looking for something happy and heartwarming, this is it. The elephants usually wear blankets to keep warm during colder months and you can purchase a blanket for an elephant on the Wildlife SOS website.

    Runners who encounter visual and auditory distractions (干扰)may be more likely to suffer leg injuries, according to research by the Association of Academic Physiatrists in Las Vegas. Runners often seek distraction from the task at hand. Whether it be music, texting, daydreaming, taking in the sights, or propping a book up on the treadmill(跑步机), more often than not a distraction is welcome. But, researchers from the University of Florida have recently discovered those distractions may lead to injury.

    Daniel Herman, MD, assistant professor at University of Florida, and his team conducted research on the effects of visual and auditory distractions on 14 runners to determine what effect these distractions would have on things such as heart rate, how many times a runner breathes per minute and how much oxygen is consumed by the body.

    The runners were all injury-free at the time of the study and ran 31 miles each week. Dr . Herman's team had each participant run on a treadmill three separate times. The first time was without any distractions. The second time added a visual distraction, during which the runners concentrated on a screen displaying different letters in different colors with the runner having to note when a specific letter-color combination appeared. The third time added an auditory distraction similar to the visual distraction, with the runner having to note when a certain word was spoken by a certain voice.

    When compared to running without distractions, the participants applied force faster to their left and right legs called loading rate, with auditory and visual distractions. They also experienced an increased amount of force from the ground on both legs, called ground reaction force, with auditory distractions. Finally, the runners tended to breathe heavier and have higher heart rates with visual and auditory distractions than without any distractions at all.

    "Running in environments with different distractions may unfavorably affect running performance and increase injury risk," explains Dr. Herman. "Sometimes these things cannot be helped, but you may be able to minimize potentially cumulative(累积的) effects. For example, when running a new route in a chaotic environment such as during a destination of marathon, you may want to skip listening to something which may require more attention - like a new song playlist."

    Dr. Herman's team will continue to investigate the potential relationship between distracted running and leg injuries, and any effect this relationship has on different training techniques that use auditory or visual cues.

    Mary went out at night. She never forgot the night when she met a robber many years ago. That evening, she was invited to a birthday party which lasted until two o'clock in the morning. Without company Mary walked along the quiet street.

    Suddenly from the shadow of a dark building a tall man with a sharp knife in his right hand ran out at her. "Good evening, lady," the man said in a low voice, "I don't think you wish to die here."

    "What do you want?" Mary asked.

    "Your earrings（耳环）. Take them off!"Slowly Mary's eyes looked down. She tried to cover her necklace with the collar（领子）of her overcoat while she used the other hand to take off both of her earrings, and then she quickly threw them on the ground.

    "Take them and let me go." She said. The robber looked at her only feeling uncertain. He saw the girl didn't care for the earrings at all, only trying to protect the necklace. He realized the necklace would cost more. So he said, "Give me your necklace."

    "Oh, sir. It's not worth much. Please let me keep it."

    "Stop rubbish. Quick!"

    With shaky hands, Mary took off her necklace. As soon as the robber disappeared, she picked up her earrings and ran as fast as she could to one of her friends.

    The earrings cost 480 pounds and the necklace the robber had taken away cost only six pounds ten shillings.

    You may have heard adults say they are uncomfortable in the morning without a cup of coffee. One reason they may feel that way is that coffee contains caffeine(咖啡因). Caffeine appears naturally in coffee, tea, and cocoa beans, which are used to make chocolate. But now food makers are adding it to many products, from potato chips to water.

    The US government is especially worried about the problem. That's why the Food and Drug Administration (FDA) is studying the health effects of caffeine on young people. Studies show that too much caffeine can make people nervous and unable to sleep. What's more, caffeine is habit- forming. Those who consume it regularly and stop suddenly may experience headaches and feel tired.

    One of the biggest concerns is the large amount of caffeine added to so-called energy drinks, like Red Bull. A 12-ounce can of cola has about 35 milligrams of caffeine. A similar serving of Red Bull contains more than three times that amount.

    The Institute of Medicine is also working on caffeine-safety measures. "Teenagers should not drink beverages that contain caffeine. They should be aware of caffeine's effects on health and on how the brain works. Take, for example, teenagers who consume caffeine to stay awake and study for a test. They will remember less of what they just studied," said Stallings, a member of the institute.

    Companies that make products with added caffeine claim they do not advertise them to kids. However, there is no law to stop children from buying them. So the FDA needs to set limits on caffeine, especially in energy drinks. As for added caffeine in foods, the government should just say no. If not, the amount of caffeine should be printed on food labels to remind consumers. The government must do that.

    Doctors say kids should avoid caffeine. If you need extra energy, try these natural boosters: eat right, exercise, and get plenty of sleep.

    Corporate culture is the values and beliefs a company develops over time. The role of corporate culture is to improve a company's mission and strategies, with long-term hopes of improvements in a company's profit. Mostly corporate culture comes from a company's top management.

    One role of corporate culture is to influence employee behavior, honesty, and compliance（服从）. A company does not have to necessarily create a direct influence for these actions. A direct influence may be a set of written regulations or other policies, and while these may be in place, the corporate culture is usually more of an indirect influence.

    While many companies try to create corporate culture through the use of written policies, its role is harder to define. The human factor has an influence on how corporate culture is expressed. The way uppermanagement acts and reacts to various situations defines how lower-level employees will act, and this aspect may be more important than any written policy.

    A company's corporate culture can also extend beyond the walls of the business. Consumers who believe a company to be honest and forthright（直率）may be more loyal in their buying behavior. Employees in a company's customer service department can also exhibit positive corporate culture to outside individuals. In this case, the culture creates a link between the company's employees and its customers. How customers react may be a direct result from the company's corporate culture.

    Product quality can also be influenced by a company's corporate culture. Companies that focus only on profits may decide to avoid high-quality materials in products, but try to suggest that the products are of higher quality than they really are. This negative culture can then result in lower brand loyalty with consumers.

    Nine years ago, a few days before Christmas, I was a director at a company in San Francisco, and I was called into a meeting that was already in progress. That meeting turned out to be my exit interview. I was 64 years old at the time. It wasn't completely unexpected. I signed a pile of papers and left the company.

    So, 40 plus years of employment was over. I had a good reputation and background. Retirement was not a choice for me. I wanted to do something. And then an idea came into my mind, born from my concern for our environment. I wanted to build my own business, designing and producing biodegradable(可生物降解的)packaging from waste. This is called clean technology, and it was really meaningful to me. It could help reduce billions of pounds of single-use plastic packaging wasted each year.

    Five years later, I'm delighted and proud to share with you that our income has doubled every year and we have no debt. Meanwhile, I have a wonderful partner, and we've won more than 20 awards for the work that we've done.

    And I am doing the most rewarding and meaningful work of my life right now. But what I really long for is to find other first-time entrepreneurs(企业家)who are my age. I want to connect with them.

    So I want to do something about that in a few years. I want us to start talking more about people who don't become entrepreneurs until they are seniors. And then connecting all of them across industries, regions and countries—building a community.
