Children who often move house are more likely to suffer poor health, research suggests. Moving several times before the age of 18 can affect the health, psychological distress and increase the chance that a child may use illegal drugs.

    The study included information for 850 people, followed-up for a period of 20 years. Scientists found changing home several times could cause psychological distress in children.

    By the age of 18, 59 percent had moved house once or twice while one in five had moved at least three times. Some 20 percent had stayed in the same house during their childhood.

    Children of single parents or those with step-parents were more likely to move home, as were those with two or three brothers or sisters. Those with four or more brothers and sisters were more likely to stay in the same house.

    Experts found that people who moved at least once had an increased risk of poor health, some of this could be because of changing schools. Those who had moved three times or more were three times as likely to have had suicidal thoughts as those who stayed in the same house.

    Dr Denise Brown said, “For many people, moving house is a good experience as it may lead to improved family conditions. But for some family members, especially children, moving can be bad and may lead to poor health outcomes and behaviors in adulthood. The bad effect on health in adulthood appears to be somewhat accounted for by a high number of school moves.”

    Facial expressions carry meaning that is determined by situations and relationships. For example, in American culture the smile is in general an expression of pleasure. Yet it also has other uses. A woman's smile at a police officer does not carry the same meaning as the smile she gives to a young child. A smile may show love or politeness. It can also hide true feelings. It often causes confusion (困惑) across cultures. For example, many people in Russia consider smiling at strangers in public to be unusual and even improper. Yet many Americans smile freely at strangers in public places (although this is less common in big cities). Some Russians believe that Americans smile in the wrong places; some Americans believe that Russians don't smile enough. In Southeast Asian culture, a smile is frequently used to cover painful feelings. Vietnamese people may tell a sad story but end the story with a smile.

    Our faces show emotions (情感), but we should not try to "read" people from another culture as we would "read" someone from our own culture. The fact that members of one culture do not express their emotions as openly as members of another do does not mean that they do not experience emotions. Rather, there are cultural differences in the amount of facial expressions permitted. For example, in public and in formal situations many Japanese do not show their emotions as freely as Americans do. When with friends, Japanese and Americans seem to show their emotions similarly.

    It is difficult to make a general statement about Americans and facial expressiveness because of personal and cultural differences in the United States. People from certain cultural backgrounds in the United States seem to be more facially expressive than others. The key is to try not to judge people whose ways of showing emotion are different. If we judge according to our own cultural habits, we may make the mistake of "reading" the other person incorrectly.

    Jane Austen has often been considered a woman who led a narrow, inhibited life and who rarely traveled. These assertions are far from the truth. Jane Austen traveled more than most women of her time and was quite involved in the lives of her brother, so much that it often interfered with her writing. Like most writers, Jane drew on her experiences and her dreams for the future and incorporated them into her writing. Her characters reflect the people around her; the main characters reflect parts of herself. In Sense and Sensibility and Pride and Prejudice, Elinor Dashwood and Elizabeth Bennet reflect aspects of Jane Austen and dreams she had that were never fulfilled.

    The biographies about Jane Austen describe the facts of her life in a step-by-step manner. They tend to be repetitive since she did not leave behind a rich fabric of day-to-day life. Yet Jane Austen is known not because of the factual details of her life; she is not remembered two hundred years after her death because she had six siblings and was a wonderful aunt to her nieces and nephews. Rather, Jane Austen is remembered because of what she wrote. Only through reading her literature does one get a taste of the real Jane Austen, the Jane Austen who dreamed and made plans for the future that failed to materialize. Only by analyzing June Austen's characters do we get an understanding of the true author.

    Sense and Sensibility's Elinor Dashwood mirrors Jane Austen's strait-laced sense of propriety (礼节) and her concern and care about family members. For example, after her father died, Jane managed to gather herself together and send her father's pocket compass and pair of scissors to her brother Frank as a memento of their father. Elinor in Sense and Sensibility is the sister who holds down the family and discusses the practicality of situations. She too distributes cherished mementos of her father when he dies. Elinor is the sister who is concerned with the welfare of her relations and takes it upon herself to look after their well-being.

    Jane can also be considered the backbone of her family. After she dies, the family is not as close as they were during her lifetime. Jane became very close with two of her nieces, Fanny Austen and Anna Austen. She counseled them on men and marriage when they reached the age of choosing a suitor. She often helped with delivering her sister-in-law's babies. During her thirties, she lived with her brother Frank for several weeks. She cooked the meals for his family and cared for his children while his wife was confined to her bed. Like the character she creates in Elinor, she sticks by her family and helps them when they need her.

    Austen's life closely parallels that of Elizabeth Bennet in Pride and Prejudice. Austen begins the novel with the line, “It is a truth universally acknowledged that a single man in possession of a good fortune must be in want of a wife”. This statement reflects the opinion of the time that a woman had to be married or else she had no social standing. Just as Elizabeth and her sisters feel immense pressure to get married and procure a good match, so too did Jane. Until she was twenty-five she still retained a small spark of hope that she would one day marry and have children.

    The most significant similarity between Jane and Lizzy is their close relationships with their sisters. Jane and her sister Cassandra were extremely close. When they moved into a house in Chawton, they shared a bedroom. They were dependent upon each other and supported each other in all aspects of their lives. They supported each other's decisions and wrote to each other when apart. Lizzy and her older sister Jane were extremely close. They too supported each other's decisions and were always there for the other. They discussed suitors and marriage just as Jane and her sister must have done.

    All of Jane's female characters end up happily married, a state Jane herself never felt. A woman was defined in terms of her husband; if she did not marry, she had nothing. Well into her twenties, Jane still had dreams of getting married. When she was twenty-five, Harris Bigg-Wither, a brother of her good friends, proposed marriage to Jane. At first she accepted: she would become mistress of a large estate, and be able to ensure the comfort of her parents to the end of their days. Most importantly, she would have children and raise a family of her own. The next day, however, Jane reneged the proposal. She did not love him and did not want a marriage based on nothing but money. After this proposal, Jane gave up all hopes of ever having a family of her own. Instead, she fulfilled her dreams through her characters and found “passion” through them. All her characters marry for love (which happens to also be financially advantageous). They make Jane's dreams become a reality within her imagination. _____ . As children reflect upon the parents and often mirror aspects of their parents, so too did many of Jane's characters mirror herself and the people around her.

    While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world's first kids to be" taught" by a digital teacher, Will. Will is just an avatar(用户头像)that appears on the student's desktop, tablet, or smartphone screen, not a human-like robot walking around the classroom.

    Auckland energy company Vector and AI company Soul Machines worked together to develop Will, which has been modeled after the human brain and nervous system, allowing it to perform human-like behavior. The digital teacher is currently assigned to teach Vector's" Be sustainable with energy, "a free program for Auckland elementary schools.

    Just like the humans it replaced, Will is able to instantly react to the students' responses to the topic. Thanks to a webcam(网络摄像头)and microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal cues(非口头提示).For instance, if a student smiles at Will, he responds by smiling back. This two-way interaction not only helps capture the students' attention, but also allows the program's developers to monitor their engagement, and make changes if needed.

    Vector's Chief Digital Officer, Nikhil Ravishankar says," What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention."

    Will, in place since August 2018,has been a great success thus far. However, regardless of how popular it becomes, Will is unlikely to replace human educators any time soon .For one, the avatar's knowledge base is severely restricted. But more importantly, even the smartest digital avatars could never predict and react to all the unexpected situations that educators have to deal with on a daily basis. However, it could come in handy as a" personal tutor", providing kids with one-on-one help on specific subjects or even topics.

    Do you often dream at night? How do you feel when you dream? Is it useful to our health? “Dreams may be more important than sleep, and we all need to dream,” some scientists say.

    Dreams take up about one quarter of our sleeping time. People have several dreams each night. Dreams are like short films. They are usually in colour. Some dreams are like old films. They come to us over and over again. That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an answer. Some people get new ideas about their work from dreams. They may have been thinking about their work all day. These thoughts can carry over into dreams.

    Sometimes we wake up with a good feeling from a dream. But often we can't remember the dream. Dreams can disappear quickly from memory.

    Too much dreaming can be harmful. The more we sleep, the longer we dream. The mind is at work when we dream. That is why we may have a long sleep and still wake up tired.

A facial expression results from one or more motions of the muscles of the face. These movements convey the emotional nonverbal communication. They are a primary means of conveying social information among humans, but also occur in most other mammals and some other animal species.

In the business world, much emphasis is placed on your first words, but it isn't all about what you say. You only have seconds to make a first impression that can make or break a relationship in business. Since the face is the first thing we notice about a person, it's vital to use your face to make that important connection.

Researchers have shown that 55 percent of non-verbal communication is facial. People generally try to mask negative expressions such as disappointment, fear or envy, but these feelings are often reflected in their eyes, or the downward turn of the mouth.

Genuine expressions of anger and surprise can be quite brief, lasting for only a few seconds. If an expression remains longer, it may be a sign of insincerity (不真诚). In general, a genuine expression matches the beginnings of a feeling, so watch for expressions that come after the words.

The research conducted last year by a team from Glasgow University, suggested that people from different cultures read facial expressions differently. Not only can that mean confusion in everyday life, but it can lead to confusion when conducting business.

The study found that East Asian participants tended to focus on the eyes of the other person, while Western subjects took in the whole face, including the eyes and the mouth. The work, which was published in Current Biology journal challenged the idea that facial expressions are universally understood. In the study, East Asians were more likely than Westerners to read the expression for "fear" as "surprise", and "disgust "as "anger".
