    Asking for salary history provides an easy way to sort applicants into an employer's desired price range and helps the employer calculate the lowest offer that will still attract a candidate. But an increasing number of U.S. states and cities agree there ought to be a law against it. Massachusetts, Philadelphia, New York City and Puerto Rico have banned salary history questions on applications and in interviews.

    Why? Because when it comes to a candidate's suitability for a job, salary history is a subjective (主观的) and often misleading indicator — and it may most affect ＂the people who have already been illegally treated,＂ says Katie Donovan, a salary negotiation coach and one of the authors of the Massachusetts law.

    Candidates who start their careers underpaid because of the gender (性别) or race wage gap, a bad economy or a cheap boss finds that this lowball (虚报低价) figure continues to weigh them down throughout their career. At the same time, senior victims of layoffs have difficulty being hired because employers assume they're not interested in senior victims.

    In an interview, you can avoid talking about salary history questions by turning the discussion to what you're looking to make.

    Donovan recommends a method similar to what you're already doing: Enter $0.00, or some other number that is clearly intended not to cheat, but to oppose.

    Of course, there's always a risk doing so because it will cost you opportunities. But Ronda Wakefield, owner of NW MT HR Solutions, says that when she receives an application with an obviously false salary history, she'll still follow up if the candidate interests her. ＂I personally don't want to miss out on a great candidate because they didn't want to answer the question directly,＂ she says.

    Recently some articles claim the word “selfie” as one of the most annoying words. But I'd like to offer that maybe it isn't not so bad.

    The “selfie” is used to describe the self taken photo, often from a smart phone. Women and men alike adorn their Instagram, Facebook and Twitter accounts with these pictures, sometimes with puckered lips or large smiles. In fact, the selfie has become so widely known that over 31 million photos on Instagram are captioned with the selfie.

    Let's think about it. Someone takes about 10 seizes each time they do, and they only end up posting one or two of those. They pick the one that they feel makes them look the best. Isn't that beautiful? In that one picture, someone has even him or herself confidence.

    Self-image is important. In society today, we are so often consumed with what society tells us is perfect. But maybe, with that one selfie, we feel like we fit that bill. We feel handsome, beautiful, confident, smart, happy and content. For that moment, everything bad or terrible that has ever happened to us is erased, because that smile or that pucker is what gives us the determination to love ourselves.

    I saw a spoken word poem recently and the young man said: If I ask you what you love the answers will most likely roll off your tongue. You love to read. You love to write. You love birds, music, tattoos… Your mom, your brother, your sister, your daughter, your best friend, your dog. How long do you think you could go on and on before you said “I love myself”？

    That statement hit me like a ton of bricks. I've struggled with confidence all of my life. I still do. And in no way am I saying that taking a selfie is a gateway to that confidence. However, the selfie does deserve some credit for allowing individuals to express themselves. Pamela Rutledge agrees, stating, “There are many more photographs available now of real people than models.”

    Billie Holiday was an American jazz singer and songwriter. Nicknamed Lady Day by her loyal friend and musical partner, Lester Young, Holiday had a great influence on jazz and pop singing. Her voiced style, strongly inspired by jazz instrumentalists, pioneered a new way of controlling tempo (节奏). Above all, she was admired for her deeply personal and direct approach to singing.

    She co-wrote a few songs, and several of them have become jazz standards, notably God Bless the Child, Don't Explain, and Lady Sings the Blues. She also became famous for singing jazz standards written by others, including Easy Living and Strange Fruit.

    Her early career is hard to track down with accuracy. But she later gained work singing in local jazz clubs before being spotted by a talent scout (星探), John Hammond in 1933.

    Her voice and recordings were loved for the depth of emotion and intensity she could bring to classic standards. Her range of voice was not the greatest, but her extraordinary low rough voice was soon to become very famous and influential.

    She was an important icon (偶像) of the jazz era and influential in the development of jazz singing. In the late 1930s, she began singing a civil rights song called Strange Fruit, a song which told the tale of a lynching (用私刑处死) of a black man in the Deep South. It was very controversial for that period and it was not played on radios. It was recorded for Commodore Records and she performed it many times over the next 20 years.

    Billie Holiday had a difficult upbringing which influenced her attitude toward life. She experienced many violent relationships. She also became increasingly dependent on various drugs which contributed to her early death in 1959, aged just 44.

    While visiting the North pole in winter may not be at the top of your bucket list, the ever-changing ICEHOTEL, which opened its doors to visitors on December 14 this year, may change your mind.200 km north of the Arctic Circle in the Swedish village of Jukkasjārvi, the hotel, which is carved entirely from ice, is rebuilt annually.

    The 35 rooms, built to accommodate visitors on all kinds of budgets, vary from expensive suites to basic rooms that are furnished with just an icy bed and a reindeer skin. Among the highlights this year is the “Spruce Woods” suite. Sculpted by Christopher Pascoe and Jennie O'Keefe of Canada, it describes a camping scene complete with a classic microbus, a forest, and even an artificial campfire.

    There is also the artfully-carved “Living Ocean” suite to remind visitors of the importance of saving our oceans. The room is full of carved sea life that includes coral and a shark “swimming” right over the ice bed. “The suite is inspired by global warming and the overfishing that affects our oceans.” says artist Jonathan Paul Green. “I also think the idea of using frozen water from a river in northern Sweden to create an ocean with shells, fish, and corals is exciting.”

    The nearby “Haven” suite is a “magical gate of ice” guarded by two large animals. “We are inspired by the meeting between people and want to create an experience that invites curiosity and creativity, "says artist Jonas Johansson." It feels like a dream to get to work with ice that allows our love for light, shine, and reflection to wander freely from thought to creation.”

    Regardless of whether visitors select the carved suites or the basic ice rooms, the temperature is always set to a bone-chilling －5℃! That is why guests are advised to snuggle(蜷缩)up inside sleeping bags and wear gloves and winter hats all night. Not surprisingly, most end up spending just a single night at this unique hotel before moving on to the conventional and warmer hotels nearby.

Growing evidence shows that dancing can boost brain health and help manage neurocognitive (神经认知的) disorders. So what is it about dance that's different from other regular exercises? 

Helena Blumen, a cognitive (认知的) scientist at Albert Einstein College of Medicine, says the complex (复杂的) mental multitasking that dance requires involves various parts of the brain at the same time. Basically, dancing requires more brain power than simpler repetitive (重复的) exercises. 

While scientists are still learning how the mechanisms of dancing work in the brain, a clearer picture is beginning to appear. Researchers at Otto von Guericke University in Magdeburg, Germany, did MRI scans of older adults who had participated in one of two programs over a six -month period. One group practiced dance and the other did a traditional exercise program with cycling and strength training. While both groups improved their level of physical fitness, the dancers grew more white and gray matter in the parts of the brain responsible for cognitive processes. Both white and gray matter typically decline as we get older, making communication in the brain slow. 

Imagine your brain is a city with loads of roads. The researchers assume the changes brought by dancing contribute to brain plasticity, which is like the city's ability to build new roads, repair old ones or even change the direction of traffic based on how often the routes are used and what the city needs. 

In addition to the physical and neurological (神经学的) benefits, dance can also help people accept what their bodies can and can't do. Dawnia Baynes, 44, developed multiple sclerosis (MS) after her body lose all feeling from the chest down. She recently joined an online dance program for people with MS. Not only has it improved her range of motion, it has also helped her overcome her fear of being judged for how she moves. 

"To see other people moving is like I'm moving," she says, "and knowing that I don't have to be professional and super technical in my dancing makes me comfortable with where I am right now."
