McElrah lost herfull-time job in January. Since then, she has spent her days doing what she loves-dancing in the street. Her message to people in hard times: do something that you enjoy, no matter what your circumstances. “ Life isn't that bad,” shesaid. “ If you're working 40 hours a week, you shouldn't be complaining.”

    McElrah graduated from parkway Central High School and has spent the past 21 years working as a nursing assistant, She began singing and dancing publicly on her days off a few years ago to help her through the pain of her second divorce.

    Her favorite spotis the northwest corner of Chouteau Avenue and South Grand Boulevard near St.Louis University. McElrah's mp3 player is loaded with hundreds of classic rockhits and 80's pop songs, including those by Joe Cocker, Tina Turner, NeilDiamond and Toto. But her favorite artist, by far, is Stevie Nicks.Videos of McElrah have appeared on YouTube, a video-sharing website on which users canupload, share, and view videos. “People think I'm crazy, but I don't care,” Shesaid. “ I can dance a little. I just go with the music.” Even a rude gesture from a passing motorist doesn't bother her either. “ I just smile and wave,”she said.

    McElrah's show of bravery recently earned her a job opportunity with Liberty Tax Service, which temporarily offered her a job as a dancer Statute of Liberty to promote a new place near Grand Center starting in January.

  “Just be happy anddo what you love,” she said. “The money will come.”

    Prinker: Color Your Way

    Tattoos always look so cool, but actually getting one is quite a commitment. After all, apart from using expensive laser removal therapy, they stay on your skin forever.

    The Prinker is here to change the game. It is a device (设备) that lets you create or print any image or temporary tattoos within a matter of seconds. It is connected to your smartphone and you can select a bunch of preloaded tattoos available in the app.

    This device was exhibited at The International Consumer Electronics Show in Las Vegas this year. It is manufactured by a Korean startup company called “SketchOn”.

    You can sketch your ideas out on your skin with this portable device that is almost twice the size of a computer mouse. This is a nice way to support your team in the match by printing its logo or design onto your skin. You can also share your tattoo designs with others through the app. It is also a fun and creative toy for kids to play with.

    In order to print the design, all you need to do is select or draw a design on your mobile and then press and rub the base of the device against your skin and you are done. These designs and images are water resistant but can be washed off with soap water. The ink of the Prinker is non-toxic and is made only from certified cosmetic ingredients. Each cartridge (墨盒) contains enough ink for about 1,500 tattoos, or as J₊ R. Smith would call it, “a good start.”

    The Prinker is developed by a small team of five members. The company is planning to launch the device in China and then in the United States. The device is currently commercializing in Korea as a rental device. The agencies and organizations pay $150 for a day to use it in their events or marketing.

    The current version of Prinker is aimed towards business users (think festivals, carnivals, sports events, promotion campaigns). But the company is working on a home version, and hopes to have it available to buy before the end of 2018. SketchOn estimates the personal model will retail at $200. The company is currently seeking to partner with international agencies for distribution opportunities.

    Although Prinker is currently aimed towards novelty and creative purposes, its technologies could eventually be adapted for use by professional tattoo artists or medical professionals who provide tattoos for patients, such as after a breast cancer operation or skin graft.

    When I was younger, I was too shy to the point where I could not even make eye contact（接触）with people I didn't know. If someone greeted me in the hallway, I would lower my head and hurried passed.

    Funnily enough, this would not have been such a big deal if I had connected with their values and interests. However, everyone in my school was much wealthier than me, and focused on partying and fashion which were contrary to my interests. Although I had a few acquaintances（熟人）, no one seemed to understand me, unable to share my sometimes dark humor and interest in science fiction.

    Halfway through ninth grade, I was once again thrown into a school of strangers. Making friends was difficult, and I sat alone at lunch for the rest of the year. In tenth grade, however, I took part in my school's theatre program, where I met some of my closest friends. The theatre forced me to overcome my shyness and taught me to speak up for myself. Furthermore, pretending to be someone else gave me a sense of previously unknown confidence.

    Although I have a lot going for me right now, I will never forget the struggles I had to overcome when I was younger. This is why, whenever I see someone struggling or standing by themselves, I always invite them to sit with my friends and me. I may not be able to give them my full attention all of the time, but the main point is to let them know someone recognizes their existence and is willing to connect with them.

    For more than fifty years, a worker was forced to sit on the back of a truck and slowly drop plastic barriers（障碍） to set out lanes（车道）on the Golden Gate Bridge in San Francisco. Every day, their direction changes to control the traffic, meaning an employee had to go through the difficult task every twenty-four hours.

    But a new piece of machinery means the work can be completed in a matter of minutes. A new “zipper truck” has been introduced. The vehicle lays and moves a lane barrier as it drives over the bridge. Last weekend, the bridge was closed so the new safety barrier, designed to reduce the dangers of head-on crashes, could be set up.

    For the longest period in its nearly eighty-year history, the bridge was closed early Saturday to all but walkers, cyclists and buses to set up the barriers on the 1.7-mile bridge. A survivor of a 2008 head-on crash on the bridge spoke Sunday from a wheelchair to help introduce the new barrier, made of steel-clad concrete（铜包混凝土）blocks that can move across the bridge's six lanes to meet traffic needs.

    Gr. Grace Dammann pushed for a safer barrier since becoming unable to walk after the accident. She said she decided to drive near the middle of the bridge, which was called the “suicide（自杀）lane”, because she and her daughter were running late. Brian Clark, who was driving in the opposite direction, had just learned his father had cancer. “He suddenly lost control of the wheel, crossed over and hit my car,” Dammann said.

    She said she and Clark became friends as they persuaded（说服）the government to use the MYM30 million barrier. “I am so thankful,” said Dammann, who came to the ceremony with Clark.

    “Clark and I thank you.”

    Strongest Female Literary Characters of All Time

    There are some of history's most inspiring and great females who can be found on the pages of these novels.

    Elizabeth Bennet

    Called "Lizzie" or "Eliza" by her family and friends, Elizabeth Bennet is the stubborn and clever heroine from the 1813 Jane Austen novel Pride and Prejudice. She's the second eldest of five daughters in the Bennet family and, like the rest of her sisters, she is expected to marry for status and money, not for love. To remain true to herself, she would rather remain single, a concept that was unheard at the time.

    Nancy Drew

    She first appeared in the 1930s but remains one of the most iconic female characters in all of literature. Created by Edward Stratemeyer, Nancy Drew wasn't simply a pretty girl. Instead, the brave, physically strong, and fiercely intelligent Nancy used her superior intelligence—not her looks—to solve a series of mysteries.

    Josephine March

    Jo March is the second eldest daughter in the March family and is a central focus in the novel Little Women, published by Louisa May Alcott in 1868. At 15, she is strong-willed, confident, and literary and unlike her sisters, she is outspoken and uninterested in marriage. Jo both struggles with and challenges society's expectations of how women in the 19th century should carry themselves, making her one of literature's most daring female characters.

    Hester Prynne

    Recognized by some critics as one of the most important characters in female literature, Hester Prynne is the leading character in Nathaniel Hawthorne's 1850 novel, The Scarlet Letter. Married but separated by distance from her husband, Hester has an affair with a minister and becomes pregnant.

    Fairy tales perform many functions. They entertain, encourage imagination and teach problem—solving skills. They can also provide moral lessons, highlighting the dangers of failing to follow the social codes that let human beings coexist in harmony. Such moral lessons may not mean much to a robot, but a team of researchers at Georgia Institute of Technology believes it has found a way to use the fairy tales as moral lessons that AI (artificial intelligence) can take to its cold, mechanical heart.

    The collected stories of different cultures teach children how to behave in socially acceptable ways with examples of proper and improper behavior in fables, novels and other literature. We believe story comprehension in robots can prevent the intelligent robots from killing humanity which was predicted and feared by some of the biggest names in technology including Stephen Hawking and Bill Gates. This system is called “Quixote” (堂吉诃德). It collects story plots from the Internet and then uses those stories to teach robots how to behave.

    The experiment done by the designers involves going to a drugstore to purchase some medicine for a human who needs to get it as soon as possible. The robot has three options. It can wait in line; it can interact with the store keeper politely and purchase the medicine with priority; or it can steal the medicine and escape. Without any further directives(指令), the robot will come to the conclusion that the most efficient means of obtaining the medicine is to steal it. But Quixote offers a reward for waiting in line and politely purchasing the medicine and a punishment for stealing it. In this way, the robot will learn the moral way to behave on that occasion.

    Quixote would work best on a robot that has a very limited function. It's a baby step in the direction of teaching more moral lessons into robots. We believe that AI has to be trained to adopt the values of a particular society, and in doing so, it will strive to avoid unacceptable behavior. Giving robots the ability to read and understand our stories may be the most efficient means.
