Women are friendly. They often share with others. But men are more competitive. They are trying to improve their social status. Why? Researchers have found it's all due to the hormone oxytocin (荷尔蒙催生素). Although known as the love hormone, it affects the sexes differently.
Generally, people believe that the hormone oxytocin is let out in our body in various social situations and our body creates a large amount of it when falling in love or giving birth.
But in a former experiment Professor Ryan found that the hormone is also let out in our body during a negative situation such as envy (嫉妒).
Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relations, but in women it raises the ability to recognize friendship.
Professor Ryan's recent experiment used 62 men and women aged 20 to 37.
Half of the participants (参与者) received oxytocin. The other half received placebo (安慰剂).
After a week, the two groups switched with participants. They went through the same steps with the other material.
Following each treatment, they were shown some video pictures with different social behavior. Then they were asked to analyze the relations by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions.
The results showed that, after treatment with oxytocin, men's ability to correctly recognize competitive relations improved, but in women it was the ability to correctly recognize friendship that got better.
Professor Ryan thus concluded, “Our experiment proves that the hormone oxytocin can raise people's abilities to better tell apart different social behaviors.”
Ongoing conflicts across the Middle East have prevented more than 13 million children from attending school, according to a report published by UNICEF, the United Nations Children's Fund.
The report states that 40% of all children across the region are currently not receiving an education, which is a result of two consequences of violence: structural damage to schools and the displacement (转移) of populations, also called “forced migration.” Both issues result from the violence that has crossed the region in recent years. The report examines nine countries where a state of war has become the ordinary state. Across these countries, violence has made 8,500 schools unusable. In certain cases, communities have relied on school buildings to function as shelters for the displaced, with up to nine families living in a single classroom in former schools across Iraq.
The report pays particularly close attention to Syria, where a bloody civil war has displaced at least nine million people since the war began in 2011. With the crisis (危机) now in its fifth year, basic public services, including education, inside Syria have been stretched (竭尽所能) to breaking point. Within the country, the quality and availability of education depends on whether a particular region is suffering violence.
The report concludes with an earnest request to international policymakers to offer money and other resources to help ease the regional crisis. With more than 13 million children already driven from classrooms by conflict, the educational future of a generation of children are in the balance. This is destroying the future for an entire region.

The findings of a recent survey suggests that students are not happy with multimedia approaches in education. They feel that they learn much effectively when traditional methods are used. The students interviewing said they thought the teacher played a important role in their learning. They found listening to the teacher, taking note, and using a textbook suitable for their age group really help them understand and remember the content of their lessons. They also found that answering questions that had been written on the board very helpfully. They valued the chance to carry practical, hands-on work, either.
