Forcing waiters and waitresses to survive on tips from customers rather than normal wages is a pointless, crude, and unique American custom that, in the past several years, a handful of progressive restaurant owners have attempted to do away with. Danny Meyer, CEO of Union Square Hospitality Group, is about to join their ranks and has announced that he plans to gradually stop tipping at the company's 13 restaurants.

    What, exactly, is wrong with tipping? As Brian Palmer has explained, more or less it's everything. To start, leaving a waiter's pay in the hands of customers has a feeling of classism (阶级歧视). And in theory, handing restaurant customers the power to tip is at least supposed to motivate better service. This fails in practice because humans turn out to be pretty arbitrary (随意的) about their tipping behavior. Research has shown that the amount diners tip has very little to do with their level of satisfaction. All of this doesn't encourage waiters and waitresses to do anything but turn over as many tables as possible.

    Tipping is also very unfair to kitchen staff. The law allows restaurants to divide tips between front-of-the-house workers like waiters, hosts, hostesses, and bartenders (调酒师), but not cooks. This creates a system in which the people serving the food in a restaurant can earn more than the people preparing it.

    One of the most fascinating parts of Meyer's move is that, unlike some restaurant owners who have taken an anti-tipping stand, he won't simply add a standard extra charge to diners' bills. Rather, Union Square Hospitality Group means to raise menu prices enough to fully cover the cost of a meal. If Meyer manages to move away from tipping at all without hurting his profits, it would almost certainly set the stage for others to follow suit.

    Inner Mongolia Autonomous Region is an important ecological screen for the north of China and even the whole country. Building a green great wall to ensure China's ecological security is one of the most important things of autonomous region.

The largest ecological function zone in the north of China, Inner Mongolia has a variety of landscapes, including forests, grasslands, wetlands, rivers and lakes. In recent years, the region's environment has improved, with its forest and grassland area having increased and desert reduced.

    However, it still faces a number of challenges in ecological preservation. For instance, the region faces severe water shortages with the number of lakes dropping from 427 in 1987 to 145 in 2010. In addition to a lack of rainfall, huge water consumption in agricultural and industrial production has worsened the water shortage. Too much use of fertilizers has damaged the soil and affected the growth of grass, accelerating the expansion of the desert, which results from a lack of water.

The local government encourages planting trees on grassland as they can get more pay for trees than by growing grass. However, the trees they plant often have a low survival rate as they have a high water consumption rate. Also, to treat wetlands, some areas have planted a large number of a single tree species. This practice may damage biodiversity (生物多样性) and endanger the survival of certain animals.

Experts suggest taking the region's water resources and weather conditions into consideration in future ecological projects.

    As the days get shorter and the chilly weather rolls in, we all want to curl up in a blanket and hibernate until spring rolls around. But making time to get outside in the sun, even when it's cold out, could have bigger mood benefits than you might realize.

    While the link between sunshine and mental health is nothing new, new research from Brigham Young University (BYU) has shown that the association may be even stronger than previously realized. It finds that sunlight exposure is by far the greatest weather-related factor determining mental health outcomes. In other words: more sunshine, more happiness.

    For the study, a psychologist, a physicist and a statistician from BYU teamed up to compare daily environmental data from the university's Physics and Astronomy Weather Station with emotional health data archived by day for 16,452 adult therapy patients who were being treated at the BYU Counseling and Psychological Services Center.

    Exposure to sunlight is a significant factor in seasonal affective disorder. Research has shown that the brain produces more of the feel-good neurotransmitter serotonin on sunny days than it does on darker days. What's more, lack of sunlight is linked with lower vitamin D levels, which in turn has been correlated with depression and low energy.

    If you're getting enough sun, your emotions should remain relatively stable, the researchers found. But as the amount of sunlight in the day is reduced, levels of emotional pain can soar. Other weather variables including temperature, pollution and rain were not found to have an impact on mental health.

    “We were surprised that many of the weather and pollution variables we included in the study were not significantly correlated with clients' scores on the distress measure once we had accounted for suntime," Dr. Mark Beecher, a professor of psychology at the university and the study's lead author, told The Huffington Post. “People tend to associate rainy days, pollution, and other meteorological phenomena with sadness or depression, but we did not find that.”

Dear Coach,

    I have been out of work for almost six months now and things are starting to get very tough for me. I am practically living out of my savings. I have been looking for a job, but things are really bad and I cannot find a single person who wants to hire me. I know that the main problem is that I do not have a degree. I want to go back to school and get my degree, but I also need a job now. I owe money to some people who have been helping me. Because I am out of work, I cannot pay them back. What do you think I should do? I need to find a job as quickly as possible, and want to know what else to do to get people to give me a chance to work for them.

The Unemployed

Dear Unemployed,

    Before you get yourself in a really bad situation, you need to stop borrowing money from people. If you continue doing that, you will be deep in debts and the situation will get even worse for you. The next thing you need to do is look for a job depending on your abilities, skills, and experience. By doing that, you will be increasing your chances of finding a job that suits you best. And the last thing I will suggest is that you should stop feeling sorry for yourself and continue working hard to get a job that you need. Borrowing money, complaining, and feeling bad for your situation will do no good to you. Stay strong and get out there and start showing the world what you can offer. I promise if you work hard and never give up, you will soon find the job that you are looking for. And while you are doing it, thing about getting your degree as well because it will help you to become more challenging. Try those tips.

My love for libraries blossomed when I joined the public library. From the age of 8 I was allowed to walk from my home to the downtown library, housed above the police station. Once the librarian gave me my first membership card, I could enjoy a range of books, which started with Little House in the Big Woods. I was addicted instantly, and this love of libraries and reading would change my life, allowing me to one day create a safe space for high-school kids, too.

By the time I was in high school, I could read the authors that we were studying in class, including Charles Dickens, Mark Twain and Emily Bronte. During the summer months, I got caught up in Gone with the Wind.

When I studied English literature at university, I thought it was time to build my own library. For the next 40 years, I continued to collect books. Until one day, I realized that all my books had become a part of the house, like wallpaper.

Toward the end of my teaching career, I became a teacher-librarian at my old high school, where I had first learned English literature. This position enabled me to regain my love and appreciation for libraries. I had a generous budget for my classes, so I searched for novels that would interest my teenage audience and hopefully spark a love of books. Fantasy, science-fiction, graphic novels -I bought almost any type of books that my students wanted to read. I bought sofas and comfortable chairs, turning the library into a safe public space, for everyone.

In doing so, I realized that the library isn't just a place to do research. They are, in fact, places that offer an opportunity to connect with the past, present and future. All that is required is a tiny bit of curiosity. Libraries are places that should be full of life. They help us adjust to the world, and their doors must be kept open to everyone for free!
