Cleaning your plate may not help feed hungry children today, but the timeworn advice of mothers everywhere may help reduce food waste from the farm to the fork, help the environment and make it easier to feed the world's growing population.

    Hard data still being collected, but experts in Chicago said about 30% to 50% of the food produced in the world goes uneaten. The average American throws away 33 pounds of food each month—about $40 worth, which means each person throws away almost 400 pounds of food. The US Department of Agriculture says that 23% of eggs and an even higher percentage of produce ends up in the trash.

"We forget we have all these fresh fruits and vegetables, and at the end of the week we have to throw them away", said Esther Gove, a mother of three young children in South Berwick, Maine. "Now, I don't buy as much fresh produce as I used to."

    But the effect of food waste arrives far beyond the kitchen. Agriculture is the world's largest user of water, a big consumer of energy and major emitter of greenhouse gases during production. Experts say reducing waste is a simple way to cut stress on the environment and can ease pressure on farmers, who will be called on to feed an expected 9 billion people around the world in 2050, compared with nearly 7 billion today.

    No matter how sustainable (可持续的) farming is, if the food's not getting eaten, it's not sustainable and it's not a good use of our resources. In richer nations, fruit and vegetables end up in the trash because they aren't pretty enough to meet companies' standards, have gone bad in a home refrigerator or aren't eaten at a restaurant. In developing countries, much food spoils before it gets to market due to poor roads and lack of refrigeration. High food prices are another reason, since some people can't afford the food that's produced.

    Most teens can't wait to learn to drive. Not so with me. Driving made me nervous. I didn't get a license until I turned 24 years old. As a result, when I first married, we only had one car and car pooled to work. My husband's hours were different from mine by one hour. I worked earlier. So he dropped me off and went to the diner to drink coffee until work time.

    Then, in the afternoons, I leisurely walked the three miles to his work place where I waited in his car, reading a book.

    One day while waiting for him, I noticed the most beautiful Cadillac pull in the lot. It was powder blue and sleek looking. The kind of car you dream about. I was busily admiring the car, when I noticed the driver. Honestly, she was probably the prettiest woman I had ever seen off the movie screen.

    She pulled into the spot beside our car and it was all I could do not to stare. There was a striking resemblance to Liz Taylor. Jet black hair and alabaster skin. Our eyes made contact and she smiled at me. Her eyes were as blue as the sea, and teeth like an even row of pearls. She was wearing a light blue shirt that just matched her car. Peeking through her long, softly curled hair I could see gold hoop earrings. They had to be gold to shine like that. A couple of minutes later, a nice looking man came out of the building, entered her car, leaned over and kissed her and she drove away.

    Sitting there in my jeans, shirt and hair in a pony tail, I wanted to cry. How could some people have it all?

    Maybe I would have forgotten about her, but the following week, I saw her again. Then it became almost routine to see her about once a week. She seemed friendly and always waved, flashing a big smile. My envy lingered long after she drove away.

    Many nights when sleep evaded me, I would think about the beautiful lady. I wondered if she and her husband ate out, and where they dined, and what she was wearing. I wanted her to get out of the car and let me see her full length. Did she wear really high heeled shoes and pants, or a skirt.

    I would get my answers in a couple of weeks.

    Sitting in our usual parking lot, I was holding my book, watching her over the top of it. She was waiting and when her husband came to the car, she called to him. They spoke a few words and he opened the car door for her to step out. He took her arm and helped her out of the car. I could see very well as she moved to get out. She was wearing a skirt.

    She haltingly walked around to the passenger side very slowly, leaning on a walking cane. Sitting sideways in the car, she lifted one leg with her hands and then the other one. The beautiful lady had a prosthesis on the left leg and a brace on the right leg. I couldn't watch them drive away as the tears were blinding me. For weeks I had envied this woman and her way of life, while I had been able to walk three miles to our car!

    When my husband arrived and found me crying, he immediately asked what was wrong. Through my tears, I told him about the beautiful lady. He said he knew her husband and also knew the story. The beautiful lady and her parents were in a car that either stalled or got caught on the railroad tracks and was hit by a train. Both parents were killed and she was severely injured. She was only 12 years old. The railroad made a large settlement with her because the crossing had no signals. He explained her car was specially built for her needs as well as the home.

    I prayed for forgiveness all the way home. The lady I thought had everything I didn't. I realized how lucky I was to have my parents, the ability to walk, run or dance through life and many wonderful things money can't buy. I would not have traded places with the beautiful lady for anything.

    When you meet a person who seems to be much better off than you, don't be fooled.

    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.

    For the past four days, the streets of India have been brightly lit and full of festivities. Millions of people around the country have been celebrating the festival of Diwali.

    Diwali has been celebrated in India for hundreds of years. It takes place each year in either October or November. Although the holiday lasts only one night, people continue to celebrate for several days.

    People light oil lamps during the festival. In the tradition of the Hindu religion, the lamps are meant to celebrate the victory of light over darkness and good over evil (邪恶). The holiday also celebrates the start of a new year in the Hindu calendar. But Diwali is an important festival in many other Indian religions as well, including Sikhism and Jainism. In a country of more than 1.2 billion people and different religious beliefs, Diwali is a celebration that touches everyone.

    Diwali means “rows of lamps” in Sanskrit, a language used in many Indian religions. During the festival, families and friends come together to light the oil lamps，which are called diyas. Then they put the lamps in rows outside their homes and temples.

    As in other cultures' winter holidays，sweets and gifts are also a big part of Diwali. Neighbors and friends share treats, called mithai, and exchange presents.

    Employers often use the holiday to express appreciation for their workers. This year, a businessman even bought cars and houses for some of his employees!

    The Diwali spirit can be felt outside India as well. Indians in countries around the world, including the U. S. and Canada，are also celebrating the holiday this week.

Guide to Stockholm University Library

    Our library offers different types of studying places and provides a good studying environment.

Zones

    The library is divided into different zones. The upper floor is a quiet zone with over a thousand places for silent reading, and places where you can sit and work with your own computer. The reading places consist mostly of tables and chairs. The ground floor is the zone where you can talk. Here you can find sofas and armchairs for group work.

Computers

    You can use your own computer to connect to the wi-fi specially prepared for notebook computers; you can also use library computers, which contain the most commonly used applications, such as Microsoft Office. They are situated in the area known as the Experimental Field on the ground floor.

Group-study places

    If you want to discuss freely without disturbing others, you can book a study room or sit at a table on the ground floor. Some study rooms are for 2～3 people and others can hold up to 6～8 people. All rooms are marked on the library maps.

    There are 40 group-study rooms that must be booked via the website. To book, you need an active University account and a valid University card. You can use a room three hours per day, nine hours at most per week.

    Storage of Study Material

    The library has lockers for students to store course literature. When you have obtained at least 40 credits, you may rent a locker and pay 400 SEK for a year's rental period.

    Rules to be Followed

    Mobile phone conversations are not permitted anywhere in the library. Keep your phone on silent as if you were in a lecture and exit the library if you need to receive calls.

    Please note that food and fruit are forbidden in the library, but you are allowed to have drinks and sweets with you.

    Facebook says it is working on technology to allow us to control computers directly with our brains. It is developing "silent speech "software to allow people to type at a rate of 100 words per minute, it says. The project, in its early stages, will require new technology to detect brainwaves without needing invasive operation. "We are not talking about monitoring your random thoughts," assured Facebook's Regina Dugan. "You have many thoughts, and you choose to share some of them. We're talking about monitoring those words. A silent speech interface（界面）-one with all the speed and flexibility（灵活）of voice. "

    Ms Dugan is the company's head of Building 8, the firm's hardware research lab. The company said it intends to build both the hardware and software to achieve its goal, and has employed a team of more than 60 scientists and academics to work on the project.

    On his Facebook page, Mark Zuckerberg added, "Our brains produce enough data to stream four HD（高清）movies every second. The problem is that the best way we have to get information out into the world-speech-can only send about the same amount of data as a 1980s modem. We're working on a system that will let you type straight from your brain about five times faster than you can type on your phone today. Finally, we want to turn it into a wearable technology that can be produced in quantity. "

    Technology is going to have to get a lot more advanced before we can share a pure thought or feeling. but this is a first step. Other ideas detailed at the company's developers conference in San Jose included work to allow people to "hear" through skin. The system, comparable to Braille, uses pressure points on the skin to pass information. "One day, not so far away, it may be possible for me to think in Chinese, and you to feel it instantly in Spanish,"Ms Dugan said.
