What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science?

    We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work.

    What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves.

    He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum(光谱).

    He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively.

    Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.

    Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place.

    These seem to be some of the ways in which a successful scientist or technologist thinks and acts.

    Sandra Cisneros was born in Chicago in 1954 to a Mexican American family. As the only girl in a family of seven children, she often felt like she had "seven fathers ", because her six brothers, as well as her father, tried to control her. Feeling shy and unimportant, she hid herself into books. Despite her love of reading, she did not do well in elementary school because she was too shy to participate.

    In high school, with the encouragement of one particular teacher, Cisneros improved her grades and worked for the school literary magazine. Her father encouraged her to go to college because he thought it would be a good way for her to find a husband. Cisneros did attend college, but instead of searching for a husband, she found a teacher who helped her join the famous graduate writing program at the University of Iowa. At the University's Writers' Workshop, however, she felt lonely—a Mexican American from a poor neighborhood among students from wealthy families. The feeling of being so different helped Cisneros find her "creative voice".

    "It was not until this moment when I considered myself truly different that my writing acquired a voice. I knew I was a Mexican woman, but I didn't think it had anything to do with why I felt so much imbalanced in my life, but it had everything to do with it! That's when I decided I would write about something my classmates couldn't write about."

    Cisneros published her first work, The House on Mango Street , when she was twenty-nine. The book tells about a young Mexican American girl growing up in a Spanish-speaking area in Chicago, much like the neighborhoods in which Cisneros lived as a child. The book won an award in 1985 and has been used in classes from high school through graduate school level. Since then, Cisneros has published several books of poetry, a children's book, and a shortstory collection.

    Optimism May Help People Live Longer

People who have an optimistic view on life are more likely to live longer, a US study said Wednesday.

    The study, published in the American Journal of Epidemiology, analyzed data from 2004 to 2012 from 70,000 women enrolled in the Nurses' Health Study, a long-running US study tracking women's health via surveys every two years.

    The researchers looked at participants' levels of optimism and other factors that might play a role in how optimism may affect mortality risk, such as race, high blood pressure, diet, and physical activity.

    It found the most optimistic women, or the top 25%, had a nearly 30 percent lower risk of dying from any of the diseases analyzed in the study compared with the least optimistic women, or the bottom 25%.

    The most optimistic women had a 16 percent lower risk of dying from cancer; 38 percent lower risk of dying from heart disease; 39 percent lower risk of dying from stroke; 38 percent lower risk of dying from respiratory disease; and 52 percent lower risk of dying from infection.

    Previous studies have linked optimism with reduced risk of early death from cardiovascular (心脑血管的) problems, but this was the first to find a link between optimism and reduced risk from other major causes.

    “While most medical and public health efforts today focus on reducing risk factors for diseases, evidence has been mounting that enhancing psychological resilience (弹性，复原力) may also make a difference,” said Eric Kim, research fellow at the Harvard T.H. Chan School of Public Health and co-lead author of the study.

    “Our new findings suggest that we should make efforts to boost optimism, which has been shown to be associated with healthier behaviors and healthier ways of coping with life challenges.”

    The study also found that healthy behaviors only partially explain the link between optimism and reduced mortality risk. One other possibility is that higher optimism directly affects our biological systems, Kim said.

    Co-lead author and postdoctoral research fellow Kaitlin Hagan said optimism can be varied with relatively uncomplicated and low-cost interventions (干预), even things as simple as having people write down and think about the best possible outcomes for various areas of their lives, such as careers or friendships.

    “Encouraging use of these interventions could be an innovative way to enhance health in the future,” Hagan said.

Does your school have any problems with discipline? What happens when students step out of line? Here are some examples of bad behaviour:

    Playing truant(missing school without permission from parents).

    Stealing, smoking, hitting, swearing(说脏话), running, kissing.

    Cheating in exams.

    Calling a teacher or another pupil bad names.

    Not doing homework.

    Not listening or not paying attention in lessons.

    Wearing unsuitable clothes.

Here are some of the ways that UK school children can be punished:

Exclusion: a pupil is asked to leave the school and not come back. The pupil has to find a new school or a different method of education.

Suspension: a pupil cannot enter the building or attend lessons until the school has a meeting about their situation. Suspension can last from one to 45 days. The pupil is usually given work to do at home with a special teacher.

Detention: a pupil is asked to stay after school and work for 30—60 minutes before they Can leave.

Lines: a pupil has to write a sentence many times(e.g.100 or more)on a sheet of paper, e, g, “I must not shout in class”.

    Freya MacDonald, a 15-year-old pupil from Scotland, made the news when she refused to accept her school's punishment. Her family says that she was given 11 detentions for trivial things in class and coming into school through a fire door.

Freya says that repeated detentions disrupted her fight to an education under Scottish law and made it difficult for her to learn. She refused to return until the school respected her civil rights. She wants the headmaster and her teachers to sign a letter to promise this. Hundreds of schools in Scotland were told not to use detention as a punishment because of her legal action.

Many UK schools now give parents a home-school contract, explaining their discipline and rules. Parents must sign this document to agree that they accept the school's rules and discipline and that they are responsible for their child's behaviour.

    America's latest superhero Austin Perine, who calls himself President Austin, is now taking the country by storm. But he is not a typical superhero. Two things set him apart: He doesn't fight human enemies, but hunger and homelessness. Also, he's only four years old.

    Our superhero's origin story started from the day when TJ Perine, his father, took Austin to the Firehouse Ministries, a local shelter that provides housing, food and other services for the homeless. As they drove by the building, they saw a group of 25 homeless men standing on the street corner. That day, Austin used his allowance to buy each man a sandwich and handed the food out himself with his slogan, “Don't forget to show love!”

    After he returned every week for five weeks in a row, word of Austin's kindness spread through social media. Austin and TJ could feed 25 to 50 people at a time before, and now, thanks to community support, they can feed 800 to 2,000 people.

    But Austin isn't merely filling stomachs. He has been improving the lives of the homeless people he meets. On that first trip to Firehouse Ministries, TJ and Austin talked to a poor man named Raymont. The respect Austin showed for him touched 41-year-old Raymont, who regained his confidence in life and finally found a job with the help of TJ. All that was made possible because a little boy took the time to care.

    Austin's passion has become his family's calling. After raising money through a GoFundMe page, Audrey, TJ's mother established the nonprofit Show Love Foundation, dedicated to fighting homelessness. She now serves as president, and TJ oversees public relations for the foundation full time. They offer medical and mental health care as preventive steps against homelessness.

    As for President Austin, he continues to give out food, smiles, and his inspirational message of love. “It makes me feel like I'm saving the day,” he said proudly.

    The World Health Organization recently said that it planned to add gaming disorder (游戏成瘾) to its new list of disease classifications, angering the gaming industry but pleasing doctors who hope it may make treatment more easily available.

    Some US experts said it would make little difference when it comes to helping people with the disorder, although others said it would bring attention to a disorder that people sometimes don't recognize. So some experts disagree WHO's plan.

    Many of us enjoy video games, but does playing our favorite game for a couple of hours every night mean we're suffering from gaming disorder? Not according to the WHO.

    The symptoms listed by the WHO include a lack of control over gaming, treating gaming more seriously than other life interests and daily activities, and continuing to play games despite the negative consequences that playing them might have.

    "The behavior pattern is enough to result in significant damage to one's personal, family, or social life." the WHO said.

    Meanwhile, Douglas Gentile of Iowa State University has carried out influential research into the cause of gaming addiction in young people." I and many others had assumed that gaming is not really a problem but is a symptom of other problems," he told NBC News. Many had thought it was simply a failure of self-control. To see if it was, Gentile's team studied a group of children who had been gaming for several years." We found that when kids became addicted, their anxiety increased … and their grades decreased," Gentile said. When kids were able to back off from gaming, their symptoms disappeared, he added.

    Gentile thinks medical organizations should pay attention to the WHO's proposal." This isn't an issue of opinion; it's an issue of science," he said." This is a major scientific and medical organization. They don't do things lightly and without reason."

    Dr Petros Levounis, chair of psychiatry at the New Jersey Medical School at Rutgers University, said that he hoped the WHO's proposal would lead to more research into obsessive (过度的) behavior among all types of people.

    "Now, there is renewed interest and excitement," he said. So some experts are in favour of WHO's plan.
