In order to help customers find what they want quickly, it's important to keep the thousands of titles in the Main Street Movies store organized properly. This section of the Employee Handbook will tell you how to organize videos.

    Each Main street Movies store has three main sections:

1). New Releases Wall.

2). Film library.

3). Video Games.

    New Releases Wall. Almost 70 percent of movie rentals are new releases, and that is the first place where most customers go when they enter the store. The center section of shelves on this wall holds Hottest Hits. When new titles come into the store, place them on this wall in alphabetical order. The shelves beside Hottest Hits are called Recent Releases. The New Releases Wall, including the Hottest Hits and Recent Releases shelves, holds about 350 titles.

    Film Library. The thousands of titles in the Film Library are organized into categories. The films within each category are displayed alphabetically. Here are the categories and their two-letter computer codes:

    Foreign Language titles include films that were originally made in a foreign language and films with foreign language subtitles. A sticker on the back of each box tells which type of film it is.

    Video Game. All the video games in Main street Movies are arranged in alphabetical order. Although video games represent only a small percentage of our inventory(库存), they are stolen more often than any other type of goods in our store. Therefore, video games are never displayed on the shelves. Shelves in the Video Game section hold cardboard with pictures and information about each game. When a customer wants to rent a particular game, you then find the game from the locked case behind the counter.

    A German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse.

    The paper, published this March in Psychology and Aging, examined health and welfare surveys from roughly 40,000 Germans between ages 18 and 96. The surveys were conducted every year from 1993 to 2003.

    Survey respondents (受访者) were asked to estimate their present and future life satisfaction on a scale of 0 to 10, among other questions.

    The researchers found that young adults (age 18 to 39) routinely overestimated their future life satisfaction, while middle-aged adults (age 40 to 64) more accurately predicted how they would feel in the future. Adults of 65 and older, however, were far more likely to underestimate their future life satisfaction. Not only did they feel more satisfied than they thought they would, the older pessimists seemed to suffer a lower ratio (比率) of disability and death for the study period.

     “We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade,” wrote Frieder R. Lang, a professor at the University of Erlangen-Nuremberg.

    Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future.

     “Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking improved precautions (预防措施),” the authors wrote.

    Surprisingly, compared with those in poor health or who had low incomes, respondents who enjoyed good health or income were associated with expecting a greater decline. Also, the researchers said that higher income was related to a greater risk of disability.

    The authors of the study noted that there were limitations to their conclusions. Illness, medical treatment and personal loss could also have driven health outcomes.

    However, the researchers said a pattern was clear. “We found that from early to late adulthood, individuals adapt their expectations of future life satisfaction from optimistic, to accurate, to pessimistic,” the authors concluded.

    Melissa Poe was 9 years old when she began a campaign for a cleaner environment by writing a letter to the then President Bush.Through her own efforts,her letter was reproduced（复制）on over 250 donated billboards（广告牌）across the country.

    The response to her request for help was so huge that Poe established Kids For A Cleaner Environment(Kids F.A.C.E.) in 1989. There are now 300,000 members of Kids FACE worldwide and is the world's largest youth environmental organization.

    Poe has also asked the National Park Service to carry out a "Children's Forest" project in every national park. In 1992, she was invited as one of only six children in the world to speak at the Earth Summit in Brazil as part of the Voices of the Future Program. In 1993, she was given a Caring Award for her efforts by the Caring Institute.

    Since the organization started, Kids F.A.C.E.members have distributed and planted over 1 million trees! Ongoing tree-planting projects include Kid's Yards—the creation of backyard wildlife habitats and now Kids F.A.C.E.is involved in the exciting Earth Odyssey, which is a great way to start helping.

    "Starting the club turned out to be a way to help people get involved with the environment. Club members started doing things like recycling, picking up litter and planting trees as well as inviting other kids to join their club."

    "We try to tell kids that it's not OK to be lazy," she explains. "You need to start being a responsible, environmentally friendly person now, right away, before you become a resource-sucking adult."

    Recent summer temperatures in parts of Australia were high enough to melt asphalt. As global warming speeds up the heat and climatic events increase, many plants may be unable to cope. But at least one species of eucalyptus tree can resist extreme heat by continuing to “sweat” when other essential processes stop, a new study finds.

    As plants change sunlight into food, or photosynthesize (光合作用), they absorb carbon dioxide through pores on their leaves. These pores also release water via transpiration(蒸腾), which circulates nutrients through the plant and helps cool it by evaporation(蒸发). But exceptionally high temperatures are known to greatly reduce photosynthesis—and most existing plant models suggest this should also decrease transpiration, leaving trees in danger of fatally overheating. Because it is difficult for scientists to control and vary trees' conditions in their natural environment, little is known about how individual species handle this situation.

    Ecologist John Drake of the S.U.N.Y. College of Environmental Science and Forestry and his colleagues grew a dozen Parramatta red gum (Eucalyptus parramattensis) trees in large, climate-controlled plastic pods that separated the trees from the surrounding forest for a year in Richmond, Australia. Six of the trees were grown at surrounding air temperatures and six at temperatures three degrees Celsius higher. The researchers withheld (扣留) water from the surface soil of all 12 trees for a month to imitate a mild dry spell, then induced a four-day “extreme” heat wave: They raised the maximum temperatures in half of the pods（three with surrounding temperatures and three of the warmer ones）— to 44 degrees ℃.

    Photosynthesis ground to a near halt in the trees facing the artificial heat wave. But to the researchers' surprise, these trees continued to transpire at close-to-normal levels, effectively cooling themselves and their surroundings. The trees grown in warmer conditions coped just as well as the others, and photosynthesis rates bounced back to normal after the heat wave passed, Drake and his colleagues reported online in Global Change Biology.

    The researchers think the Parramatta red gums were able to effectively sweat — even without photosynthesis — because they are particularly good at tapping into water deep in the soil. But if a heat wave and a severe drought (干旱) were to hit at the same time and the groundwater was exhausted, the trees may not be so lucky, Drake says.

    Other scientists call the finding encouraging. “It's definitely good news,” says Trevor Keenan, an ecologist at Lawrence Berkeley National Laboratory, who was not part of the study. “It would be very interesting to know how this translates to other species,” he adds. Drake hopes to conduct similar experiments with trees common in North America.

    Friendships can be difficult—because often people aren't as honest and open as they should be. Sometimes, people end up getting hurt.

    Most problems with friendships come up because people are just too selfish to care about the things that their friends need. They care about their own needs much more, which makes it hard for friendships to work. However, being selfish is part of human nature. A person is put together in order to take care of himself and his own needs, not necessarily those needs of other people. Even though being selfish is something that all humans are born with, it is something that everyone should guard against.

    The best thing to remember when you are a friend to anyone is that you need to treat your friend the same way as you'd like to be treated. This is wonderful advice for a friendship, because it is really the only way to make sure that you are giving your friend everything you would want to be given in a friendship. Whenever you have a question about how you should treat a friend, it is easy to find an answer simply by asking yourself what you would like your friend to do for you, if he or she is in your shoes.

    Even if you're always thinking about how you'd like to be treated, and your friends are too, there are issues that come up from time to time in each friendship, and it is important to understand how to deal with these issues so that you can build stronger and healthier friendships. Issues like friends getting boyfriends or girlfriends and not spending enough time with their friends, or even friends finding new friends and leaving old friends behind are issues that will probably come up with one or more of your friendships. It is important to know how to deal with these issues so that you can keep your friends and make new ones. No one wants to have a broken friendship.

    One of my favorite hobbies is exchanging old-fashioned, paper-with-a-stamp-on-it postcards with random strangers around the world.

    The Postcrossing Project was created by Paulo Magalhaes in 2005. He liked getting mails—especially postcards. He thought others did, too—but how could he connect with them? That's when he came up with the idea of an online platform (postcrossing.com): There, postcard lovers like me can sign up to send a postcard to someone who has registered online, and receive a postcard in return.

    Along with a randomly selected address, participants get a unique code to put on the postcard. When the postcard arrives, the recipient registers that code with the site, which then causes the sender's address to be given to another postcrosser in turn. In practice, this means that for nearly every postcard I send (a few get lost in the mail) I get one back. And since I never know who will send me a card or where in the world they live, every trip to the mailbox holds the potential for a wonderful surprise.

    Privacy-conscious Americans might worry about sharing their address with strangers overseas. But postcrossers are friendly, polite, respectful folks—in more than 450 cards exchanged, I've yet to have a bad experience.

    On days when the international news is depressing, postcrossing is my comfort. There's nothing like getting a card from a child in China just learning to write in English, or a grandmother in Belarus describing her most recent gardening success to remind me that we truly are members of one global family, far more similar than we are different.

    It seems like such a small thing to send out a postcard. But as travel and communication technology continue to shrink the world, it's important to remember that it isn't just for diplomats and politicians to represent our country anymore. All of us have the power—and perhaps the responsibility—to be ambassadors, to show the best of your country to the world.

    And it's good to know that what you need to accomplish this is not necessarily complicated or expensive. It can be as simple as a postcard.
