Imagine that you're looking at your company-issued smartphone and you notice an e-mail from Linkedln: “These companies are looking for candidates like you!” You aren't necessarily searching for a job, but you're always open to opportunities, so out of curiosity, you click on the link. A few minutes later your boss appears at your desk. “We've noticed that you're spending more time on Linkedln lately, so I wanted to talk with you about your career and whether you're happy here,” she says. Uh-oh.

     It's an awkward scene. Attrition (损耗) has always been expensive for companies, but in many industries the cost of losing good workers is rising, owing to tight labor markets. Thus companies are making greater efforts to predict which workers are at high risk of leaving ,so that managers can try to stop them. Methods range from electronic monitor to well-designed analyses of employees' social media lives.

     Some of this work may be a reason to let employees to quit. In general, people leave their jobs because they don't like their boss, don't see opportunities for promotion or growth, or are offered a higher pay; these reasons have held steady for years.

    New research conducted by CEB, a Washington-based technology company, looks not just at why workers quit but also at when. “We've learned that what really affects people is their sense of how they're doing compared with other people in their peer group, or with where they thought they would be at a certain point in life, says Brian Kropp, who heads CEB's HR practice. “We've learned to focus on moments that allow people to make these comparisons.”

Technology also provides clues about which star employees might be eyeing the exit. Companies can tell whether employees using work computers or phones are spending time on (or even just opening e-mails from) career websites, and research shows that more firms are paying attention to these things. Large companies have also begun searching for badge swipes (浏览痕迹)—- employees' use of an ID to enter and exit the building or the parking garage—to identify patterns that suggest a worker may be interviewing for a job.

    Smoking is harmful. But as soon as you quit the habit, everything will be OK, right?

    Wrong

    New research has found that even if you give up smoking, the damage it has done to your genes(基因) will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed—a number that is one-third of known human genes.

    According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.

    When you stop smoking, a lot of these genes will return to normal within five years.

    This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years. It's almost like leaving a footprint on wet cement (水泥)—it will always be there, even when you've walked away and when the cement becomes dry.

    Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.

    Exploit your parking space

    An unused parking space or garage can make money. If you live near a city center or an airport, you could make anything up to £200 or £300 a week. Put an advertisement for free on Letpark or At my house park.

Rent a room

    Spare room? Not only will a lodger（房客）earn you an income, but also, thanks to the government-backed “rent a room” program, you won't have to pay any tax on the first £4500 you make per year. Try advertising your room on Roomspare or Roommateeasy.

    Make money during special events

    Don't want a full-time lodger? Then rent on a short-term basis. If you live in the capital, renting a room out during the Olympics or other big events could bring in money. Grashpadder can advertise your space.

Live on set

    Renting your home out as a “film set” could earn you hundreds of pounds a day, depending on the film production company and how long your home is needed. A quick search on the Internet will bring up dozens of online companies that allow you to register your home for free—but you will be charged if your home gets picked.

Use your roof

    You need the right kind of roof, but some energy companies pay the cost of fixing solar equipment (around £14,000), and let you use the energy produced for nothing. In return, they get paid for unused energy fed back into the National Grid. However, you have to sign a 25-year agreement with the supplier, which could prevent you from changing the roof.

    My mother loves flowers. As soon as warm weather comes around, you will find her planting, watering and weeding over everything. For many years we lived next door to each other, and she spent as much time in my garden as she did her own. After the flowers became plentiful each summer, she would cut colorful bouquets (花束) to enjoy inside the house－both hers and mine. I would often come home from work and find a beautiful arrangement (布置) of fresh flowers on my coffee table.

    Shortly before Christmas one year, a local flower shop offered a bouquet month special. It seemed to be a great way to thank her for all of the flowers she had given me through the years. After the holidays, in early January, I drove her to the flower shop to pick up her first month's bouquet. The small fresh colorful bouquet would hardly fill a small vase (花瓶).

    I was so embarrassed(尴尬的). However, after we returned home, she began to arrange the flowers she had received. “Mom, I'm sorry,” I told her. “I can't believe how skimpy that bouquet is.” She looked at me and smiled. “It's okay,” she said. “It allows me to better enjoy the beauty of each one.”

    Mom's words helped me to realize something bigger and more important－when we have too many good things, we often fail to enjoy the beauty of each one.

      Thanks, Mom, for helping me understand that less is sometimes more.

    Summer's here and it won't be long before school-aged kids across America start complaining that they're tired of riding their bikes, playing at the park, swimming in the pool...and all the other awesome activities their parents hoped would keep them pleasant for the next 10 weeks. Well, if it's any comfort, such rapid boredom could suggest that the kids have amazing powers of memory. A new study shows that the better your short-term memory is, the faster you fed sated (过饱的）and decide you've had enough.

    "Though satiation can be physical, like when you feel full after eating too much, we were interested in the psychological (心理学的）side of satiation. Like when you're just tired of something," Noelle Nelson, assistant professor of marketing and consumer behavior. She and her colleague Joseph Redden at the University of Minnesota tried to think outside the lunch box." Something that was interesting to me is that some people get tired of same things at very different speeds. So if you think about pop songs on the radio, some people must still be enjoying them and requesting them even after hearing them a lot. But a lot of other people are really sick of those same songs."

    The difference, the researchers thought, might have to do with memories of past experiences. For example, studies show that people push away from the dinner table sooner when they're asked to describe in detail what they ate earlier for lunch.

    So the researchers tested the memory capacity (能力） of college students, The students then viewed a repeating series of three classic paintings…like The Starry Night, American Gothic, and The Scream...or listened and re-listened to a series of three pop songs...or three pieces of classical music. Throughout the test, the students were asked to rate （定等级） their experience from zero to tan. And the better a participant scored in the memory test, the faster they got bored." We found that people with larger capacities remembered more about the music or art, which led to them getting tired of the music or art more quickly. So remembering more details actually made the students feel like they'd experienced the music or art more often."

    The findings suggest that marketers could control our desire for their products by figuring out ways to keep us from fully remembering our experiences. We could also trick ourselves into eating less junk food by putting ourselves in the memory of a previous (之前的) snack. As for kids easily bored, just tell them to forget about it—it might help them have more fun.

    Cropping (修剪) an Image With the Snap Shot Program

    Welcome to the world of photo-editing!

    Cropping an image allows you to zero in on (对准，聚焦) just the portion that is important to your project. For example, you may want to insert an image of a covered train in a report but may not want to include the whole train. Cropping the image allows you to select only the small area you wish to retain (保留) and eliminate all other portions of the original picture.

    Option 1: Cropping by Placing the Image in a Shape

    Screen Shot 1

    Using one of Snap Shot's standard shapes as a photo-editing tool requires no special abilities to crop an image with a standard shape:

    a. Click Cropping & Orientation from the Effects menu.

    b. Click to select one of the six shapes to frame your image.

    c. Use the mouse pointer to draw a frame around the portion of the image you wish to retain. Re-size the frame by dragging the shape's sizing handles. When you are satisfied with the results, click Cut It.

    d. Snap Shot will automatically return to the project that is open. (You may also copy or cut the cropped image and paste it into another application.)

    Option 2: Freehand Cropping of an Image

    Screen Shot 2

    If you want to trace the shape of an object in order to crop out everything else, freehand cropping is the way to go. To crop an image freehand:

    a. Click Freehand Crop from the Cropping & Orientation option on the Effects menu.

    b. Using the mouse pointer, trace around the shape you want to crop. Be sure to completely enclose the image by ending at the same place you began outlining.

    c. Click Cut It. Snap Shot will automatically return to the project that is open.
