BEIJING, Nov. 27 (Xinhua) -- A government official on Sunday refuted an accusation that discriminations widely exist in the country's civil service recruitment process.Nie Shengkui, director of the examination and recruitment department of the State Administration of Civil Service (SACS), said that the recruitment process is always based on the principles of justice and fairness, which has promoted the upward mobility of people from the grassroots.The ratio of recruited male and female applicants is around 6 to 4 in last year, equal to the ratio of the male and female applicants, and more than 92 percent of the recruited are from the ordinary families in the grassroots, including 29 percent from the rural areas, according to Nie.Nie's words came after a survey report published earlier last week, accusing the authorities of having discriminatory requirements in civil servants recruitment.Conducted by the Constitutionalism Research Institute of China University of Political Science and Law, the survey report said that without publicly acknowledging any form of discrimination, many public offices don't hesitate to hide their preferences on age, gender, education and state of health in recruitment.Nie defended that it is necessary to set some requirements in the recruitment in a bid to guarantee the future civil servants can carry out there duty competently."Civil servants recruitment is a process of choosing talents for the government to manage the country, not for promoting employment," said Nie, "so there is nothing to do with employment discriminations."Chinese college grads are usually enthusiast about finding jobs within government branches, especially at a time when people are trying to secure a stable future amid a troubled global economy.A total of 970,000 applicants took the general exam of the recruitment on Saturday and Sunday, They will compete for only 18,000 posts in central government departments and their local branches.

BEIJING, Nov. 30 (Xinhuanet) -- Heading football frequently may cause brain damage leading to subtle but serious declines in thinking and coordination skills, a new study suggested as quoted by media reports Wednesday.Researchers used an advanced MRI (Magnetic Resonance Imaging) technique to analyze changes in brain white matter of 32 adult amateur soccer players who head balls 436 times a year on average.The study found players who head football quite frequently -- with 1,000 or more a year -- showed abnormalities similar to traumatic brain injuries suffered in car accidents."This is the first study to look at the effects of heading on the brain using sophisticated diffusion tensor imaging," said Dr. Michael Lipton, a leading researcher and associate director of the Gruss Magnetic Resonance Research Center at the Albert Einstein College of Medicine in New York City."We found the real implication for players isn't from hitting headers once in a while, but repetitively, which can lead to degeneration of brain cells," he added.The researchers compared neurological images of study participants, whose average age was 31, and found those with the highest volume of headers had abnormalities in five areas of the brain, responsible for attention, memory, physical mobility and high-level visual functions.The findings come in the wake of mixed reports on the so-called "cognitive" consequences of frequently heading soccer balls at practice.Dr. Chris Koutures, a pediatrician and sports medicine specialist in Anaheim Hills, California, said the retrospective imaging study was fascinating, but needs more data to effectively determine safe header limits, especially for younger players.Dr. Lipton agreed neuropsychological damage from headers would be hard for a coach or physician to notice since cognitive problems develop gradually, and even players might not be aware of mild memory loss."We can't tell an individual today not to be heading a ball, but caution is a good thing," Lipton said. "We need more research for definitive answers and we have the advanced imaging tools to do it."

BEIJING, Jan. 22 (Xinhua) -- China restored 23,000 hectares of wetlands in 2011, according to the latest figures from the State Forestry Administration (SFA).An SFA spokesman said China reinforced wetland protection in 2011 by increasing subsidies in protecting wetlands. In the year the country carried out 42 wetland protection projects, increased 330,000 hectares of protected wetland areas, added four wetlands of international importance and 68 national wetland parks.The spokesman said in 2012 the country will further step up wetland protection and restoration, finish the second national wetland resources investigation and carry out pilot projects in assessing healthy conditions of the wetland ecological system.So far China has built more than 550 wetland natural reserves, 37 wetlands of international importance, which were listed in the Ramsar international wetland convention, and 100 national wetland parks. About half of the country's natural wetlands have been brought under effective protection, the SFA said.

VIENNA, Oct. 7 (Xinhua) -- A sculpture of late Soviet cosmonaut Yuri Gagarin was presented to the UN Office in Vienna (UNOV) Friday to celebrate "50 Years of Human Spaceflight," the theme of the World Space Week 2011.In 1961, Gagarin completed an orbit around the Earth aboard the Vostok 1 spacecraft, serving as a pioneer of human spaceflight.The sculpture is a gift from the Russian government and would be placed at the Permanent Exhibit of the United Nations Office for Outer Space Affairs (UNOOSA).Attendants of the ceremony include UNOV Director-General Yury Fedotov, UNOOSA Director Mazlan Othman and Head of the Russian Permanent Mission Vladimir Voronkov."Outer space is one of the most exciting and challenging topics, and perhaps of all the important topics on the agenda of the United Nations, none quite captures our imagination like outer space," Othman said in her statement.Meanwhile, speaking highly of Gagarin's achievement 50 years ago, Fedotov stressed that the purpose of the development and utilization of outer space must be to the benefit of all mankind.The UN official said that relevant UN agencies would provide technical assistance to all countries to develop outer space and ensure the benefits in peaceful purpose.On Dec. 6, 1999, the 55th United Nations General Assembly declared the World Space Week to be held every year during Oct. 4-10.

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.
