BEIJING, Nov. 9 (Xinhuanet) -- Kids with a depressed father tend to have more behavior issues than those with a happy father, a latest US study shows.The study, published in the journal Pediatrics, used data from home interviews with almost 22,000 families. All of them had a child aged between five and 17, and both a mother and father living at home, according to a Reuters report Tuesday.After analyzing the data, researchers found 11 percent of the children with a depressed father had problems at home or at school, whereas only six percent of those with a happy father had such problems.This is one of the first large-scale studies focusing on the connection between depressed fathers and children's behavior, said study author Michael Weitzman from the New York University School of Medicine.In addition, the study echoed the previous finding that mothers' depression could increase children's emotional and behavior problems.It was reported that 19 percent of the children in the study struggled emotionally and behaviorally if their mother was depressed."Parents who are depressed tend to engage less with their children, tend to display less positive behaviors, and display more harsh, negative and critical behaviors," said Jeremy Pettit, a psychologist not involved in the study, cited by Reuters.
BEIJING, Oct. 20 (Xinhuanet) -- A Teenager's intelligence is not fixed as usually thought. Instead, it can go through swings in a few years, according to a British study reported online in Nature.Teenagers' IQ can rise or fall 20 points over time, researchers from Wellcome Trust Centre for Neuroimaging of Kings College, showed in their study.IQ (short for "intelligent quotient") is an gauge of mental capability measured through a series of standardized tests of language skill, spatial ability, arithmetic, memory and reasoning.To get the findings, Cathy Price, senior researcher of the study, and her colleagues tested 33 British teenagers between the ages of 12 to 16 in 2004, who had average IQ scores around 100. Then the teenagers were retested four years later.The researchers found the volunteers' IQ scores went up and down over the four years, with some teenager's scores rising by as many as 20 points, and others' dropping by the same points."That is quite astounding," cheered psychologist Robert Plomin from the same university but not involved in the study. Dr. Price and her colleagues don't know the causes of such fluctuations in the scores they tested, but speculate that learning experiences might account the changes, reported by the Wall Street Journal Today. "We have to be careful not to write off poorer performers at an early stage when in fact their IQ may improve significantly given a few more years," stated Dr. Price cited by the Huffington Post.
BRUSSELS, Nov. 7 (Xinhua) -- China and Europe should strive to strengthen their cooperation for a win-win outcome in this era of profound changes, said a senior Chinese official here on Monday.Liu Yunshan, a member of the Political Bureau of the Communist Party of China (CPC) Central Committee, made the remarks during his keynote speech at the opening ceremony of the China-Europe High-Level Political Party Forum.Chinese President Hu Jintao has expressed a readiness to work for world economic recovery and strong, balanced and sustainable growth at the G20 summit in Cannes, France last week, said Liu, who is also head of the Publicity Department of the CPC.Liu Yunshan(Front, 3rd,R), a member of the Political Bureau of the Communist Party of China (CPC) Central Committee, attends the opening ceremony of the China-Europe High-Level Political Party Forum in Brussels on Nov. 7, 2011. The forum kicked off in Brussels on Monday.The forum would carry on with discussions on the new possibility and new measures of cooperation between China and Europe, which would add new spurs to their relations, said the Chinese official.Liu called for more cooperation for a win-win result and mutual respect for cultural differences between China and Europe, as well as a common effort to build an inclusive and open international system to face up to global challenges.Noting that China and Europe are stepping into a new stage of development for their ties, Liu expressed hopes that both sides further enhance their strategic mutual trust, "respect each other's core interest and major concerns and observe each other's development from a more objective perspective."Efforts should be made to promote their cooperation in trade, finance, environment protection, high-tech and new energy, and China and Europe should also work to cultivate new growth possibilities for their economic and trade cooperation, he said.They should in the meanwhile expand people-to-people exchanges and take the chance of their intercultural dialogue year in 2012 to build on their friendship, he added.Leaders from the European political parties said the forum offered chance for a key high-level dialogue for the political parties in China and Europe, which would play an active role for the exchanges and comprehensive development of the relations between both sides.
WASHINGTON, Jan. 2 (Xinhua) -- A systematic review of previous studies suggests that there may be a positive connection between physical activity and children's academic performance, according to a report published Monday in the Archives of Pediatrics & Adolescent Medicine.A group of scientists at the Vrije Universiteit (Free University) Medical Center in the Netherlands reviewed evidence on the relationship between physical activity and academic performance because of concerns that pressure to improve test scores may often mean more instructional time for classroom subjects with less time for physical activity.The authors identified 10 observational and four interventional studies for review, 12 of which were done in the United States, one in Canada and one in South Africa. Sample sizes ranged from 53 to about 12,000 participants between the ages of eight years and 18 years old. Follow-up varied from eight weeks to more than five years."According to the best-evidence synthesis, we found strong evidence of a significant positive relationship between physical activity and academic performance. The findings of one high-quality intervention study and one high-quality observational study suggest that being more physically active is positively related to improved academic performance in children," the report said.Background information in the article suggests that exercise may help cognition by increasing blood and oxygen flow to the brain, increasing levels of norepinephrine and endorphin to decrease stress and improve mood, and increasing growth factors that help create new nerve cells and support synaptic plasticity."More high-quality studies are needed on the dose-response relationship between physical activity and academic performance and on the explanatory mechanisms, using reliable and valid measurement instruments to assess this relationship accurately," the report concluded.
BEIJING, Oct. 2 (Xinhua) -- Chinese archeologists have found evidence indicating that the mysterious ancient city of Loulan (Kroraina) once had highly-developed agricultural systems.Scientists from the Institute of Geology and Geophysics under the Chinese Academy of Sciences conducted remote sensing procedures, field investigations and sample testing in the area and found that there were once large tracts of farmlands in Loulan.The farmland featured regular and straight circumferences stretching for 200 to 1,000 meters as well as irrigation ditches running throughout, said Qin Xiaoguang, a member of the research team.Moreover, researchers found grain particles in the area's ground surface, which are very likely to be remains of crop plants, Qin said.These findings show that irrigation farming had been practiced in Loulan for at least 100 years, Qin said.Qin said they also found canal remains measuring 10 to 20 meters wide and 1.6 meters deep in the Loulan relics, indicating that the city, which is suspected of perishing in drought, was once rich in water resources.The ancient city was a pivotal stop along the famous Silk Road, but mysteriously disappeared around the third century AD.Previous historical records suggested that Loulan's economy was sustained by widespread agricultural activity, but no remains or other evidence had been found before the most recent discoveries.
