Researchers from France and Italy discovered that Canadian parents are less strict with their children than mothers and fathers in France and Italy.

    “Our most important finding was the difference between Canadians and the others,” said Professor Michel Claes, the lead author of the study. “Canadians focus on independence and negotiation. On the other hand, Italians, for example, exercise more control. We found Canadians seem to focus on negotiation in case of a conflict.”

    Claes said Canada, France and Italy were selected for the study because they share important cultural and social factors. “We chose French­Canadians because they share the same language as France, and originally came from France and share certain values. Italy was included because it was considered to have similar, strong and important family values,” he explained.

    The researchers examined the emotional ties between parents and their children by questioning 1,256 students aged 11 to 19 years old.

    Canadian students reported less control and more free actions, according to the study. Italian parents were stricter and French parents were somewhere in the middle.

    Claes explains that the differences lie in education in Canada, France and Italy.

    “North America has its own educational values, which promote individualization. Tolerance and comprehension are encouraged. Italy, on the other hand, promotes respect of authority, control, and the need for permission.” he said.

    Children from all three countries described their mothers as warm and communicative. Italian and Canadian children had similar feelings about their fathers, and reported high levels of emotional ties. But French fathers were generally thought by their children to be more distant and cold.

    “We were surprised by this,” Claes admitted.“It seems as though the relationships between French mothers and their children were becoming closer over time, while fathers maintain a form of distance and coldness, which is more of a source of conflict in France than in the other countries.”

    The Speaker was the title of an eight-part television series. It was produced by the BBC in the UK. The aim of the series was to find Britain's best young speaker.

    Young people between the ages of 14 and 18 from across the country were invited to take part in The Speaker. Applicants included tough-talking teens, jokers, and shy, sensitive types. The one thing they had in common was a desire(渴望) to talk publicly and enthusiastically about what was important to them.

    Each applicant was asked to prepare and film a one-minute speech on any subject-from pop music to politics, from hooligans(小流氓) to homework. From all the entries received, 160 speakers were chosen by three judges. These speakers were invited to the next stage of regional auditions(海选), where they had to deliver their one-minute speech again, but this time in front of the judging panel(评审团) and an audience. Of the 160 speakers, only 20 were selected by the judges to go through to the next stage. They then had to give another speech on a subject they were given only seconds before making the speech. Some competitors also had to speak about a picture, again without any preparation.

    The final eight were then coached by celebrity mentors(指导老师) and given new challenges to help improve their speaking skills. Their speeches were judged by the judges and their mentor. By the last part in the series, which was shown at the end of April 2009, only three competitors remained. They were taken on a research trip to Malawi, where they found out first hand the effects of children's rights, ahead of their final speech. Duncan Harrison, a 14-year-old schoolboy from Bristol was chosen as the winner by the judges and mentors.

    When asked what makes a good speaker, the actor, director and teacher, Jeremy Stockwell, who was one of the judges on the series, said, “An effective speaker must know and trust who they are, what they have to say, and why they have to say u. Whether you're playing Hamlet, delivering a political message or presenting a school meeting, you must have a story to tell, a message to pass on and a clear sense of purpose.”

    During his first week as a new Atlanta police officer, Officer Che Milton answered a call for shoplift at the nearby Family Dollar store. When he arrived, Milton found a 12-year-old girl in tears over trying to steal a $2 pair of shoes. Crying, she told Milton that the shoes were supposed to surprise her 5-year-old sister.

    Milton, instead of arresting the girl, asked her to take him to her home instead. When he arrived, Milton's heart sank. He found a house nearly empty, with only a sofa and sheets on the floor instead of beds. There was no food in the kitchen and the kids were there. The girl's mother told the officer that her husband worked but didn't make much money and that she couldn't afford to do the same with several children to take care of and no daycare money to spare.

    Moved, the officer drove to a restaurant and bought four pizzas for them and he called the Division of Family and Children Services and asked if there was a social worker who could help.

    When the police department found out about Milton's trips, instead of punishing him, the department decided to share his story on Facebook and added that “not only is he here to enforce(实施) the law but also to go the extra mile and be a bigger part of the community he is policing.”

    Hundreds of citizens liked the post, asking how they could help. The department followed with posts including the six children's sizes and mother's clothing sizes. It also called for blanket and furniture donations. Visit the posts to learn how you can help and find more useful ways to donate your old things.

    People love cellphones, which is why nine in ten Americans own one. But does heavy use of cellphones pose a risk of cancer? This question has caused controversy for many years. A new study in rats now augments those concerns. Its data linked long-term, intense exposure to radiation from cellphones with an increased risk of cancer in the heart or brain. The results have yet to be confirmed, the authors note.

    Indeed, although the rat study found a link between cellphone radiation and cancer, it offers no clues to why such a link might exist, notes Jonathan Samet. He teaches preventative medicine and directs the Institute for Global Health at the University of Southern California in Los Angeles. Still, he calls the new study's findings “significant”.They could lead to studies researching how cellphone radiation might cause cancer, he says.

    Phone signals are relayed between cell towers and cellphones via radio waves. This radio frequency—or RF—radiation is a type known as non-ionizing (非电离的).Unlike X-rays, non-ionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules, producing ions. So it tends to be far less harmful than ionizing radiation, such as X-rays. But that does not mean radio waves might not cause harm.

    In very large doses (量) this radiation will heat the body and cause tissue damage. But it's not yet known what much lower RF levels might do, such as those from cellphone use. Five years ago, the World Health Organization's International Agency for Research on Cancer, or IARC, concluded that cellphone use “is possibly carcinogenic (致癌的)”.

    Its conclusion was based on what little research data was available at that time. But notice that IARC was not certain. It said only that phone use might “possibly” cause cancer. So scientists at the National Toxicology Program, or NTP, investigated further.

    To be sure, only children experienced some things differently from those with sisters and brothers. Many feel more pressure to succeed. They also tend to look only to their parents as role models in the absence of brothers and sisters.

    In India, 10-year-old Saviraj Sankpal founded a support group for the tiny minority(少数) of only children. Among other things, the group does volunteer work to fight against the false idea that they are not responsible. "People think we're treated too kindly and ruined," says Sankpal, a computer engineering student. "But I'd like to remind them how lonely it can get."

    Most only children, however, say they wish for sisters or brothers only when it comes to caring for aging, unhealthy parents. Britain's David Emerson, co-author of the book The Only Child, says that such a person has to make all the decisions alone. Emerson knows from experience. After his father died, he chose to move his elderly mother from their family home, where she was vulnerable (易受攻击的) to house breakers, to a new one with more safety. "The move was quite hard on her, and she might feel that I pushed her into it, "he says, "After all, I am left with that responsibility."

    In the future, more and more only children will probably face similar choices. With working mothers increasing, many families are finding they simply don't have the time, money or energy to have more than one child. As only children become common, perhaps the world will realize that the charge made against them is unfair.

    Being able to land safely is a critically important skill for all flying animals. Comparatively speaking, ground living animals face no particular challenge when they need to stop running or crawling, while flying animals move at much higher speed, and they must be careful about how they land. Hitting the ground, or even water, at full flight speed would be quite dangerous. Before touching down, they must decrease their speed in order to land safely. Both bats and birds have mastered the skill of landing, but these two types of flyers go about it quite differently.

    In the past it was believed that, in terms of flying mechanics, there was little difference between bats and birds. This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings. In recent years, though, researchers have discovered a number of interesting facts about bat flight. Bats are built differently from birds, and their wings are made up of both their front and hind limbs (肢体). This makes coordinating (协调) their limbs more difficult for bats and, as a result, they are not very good at flying over longer distances. However, they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or completely reverse it, something a bird cannot easily do.

    Another interesting characteristic of bat flight is the way in which bats land-upside down! Unlike birds which touch down on the ground or on tree branches, bats can be observed flying around and then suddenly hanging upside down from an object overhead. One downside to this landing routine is that the bats often land with some force, which probably causes pain. However, not all bats hit their landing spots with the same speed and force; these will vary depending on the area where a bat species makes its home. For example, a cave bat, which regularly lives on a hard stone ceiling, is more careful about its landing preparation than a bat more accustomed to landing in leafy treetops.
