MOSCOW, Dec. 17 (Xinhua) -- Russia had ambitious goals and looked forward to regaining the title of leading space power by 2023, a leading scientist said Tuesday.


Russia had been working out a long-term program of Moon exploration aimed at building a permanent lunar base, said Lev Zelyony, director of the Russian Academy of Science's Space Research Institute.


"The Moon could be treated like Earth's seventh continent. By mid-century, a fierce competition for possession of the Moon poles will start," Zelyony told a meeting in the Mission Control Center near Moscow chaired by Deputy Prime Minister Dmitry Rogozin.


Zelyony compared the prospective Moon race with the current competition between world powers over the Arctic.


If the Moon base is built Nike Air Max 97 Soldes Pas Cher , maintenance of the International Space Station would become secondary or even unnecessary, the scientist said.


He said Russia would start by sending one Moon orbiter and two Moon rovers intended to deliver lunar soil to Earth, he said.


Rogozin, who is in charge of the national military-industrial complex, has sided with the scientist, saying Russia has got everything to become a leader in space exploration, including creation of an anti-asteroid shield and building a Moon base.


CHICAGO Nike Air Max 90 Soldes Pas Cher , Sept. 19 (Xinhua) -- When children believe they can succeed in math and reading, it increases their chances later to achieve high test scores in those subjects, a study jointly conducted by the University of Michigan (UM), Pontificia Universidad Catolica de Chile and Independent Scholar shows.


Researchers used two U.S. data sets, one being a nationally represented study and one U.K. data set to measure self-concept and standardized assessments of early and later academic achievement. The data involved 13,901 British children and 1,591 American children aged five to 18.


Allowing for children's earlier achievement and their characteristics and backgrounds Nike Air Max 2019 Soldes Pas Cher , including birth weight, ethnicity, gender, age and their mother's education, the researchers found that children's self-concept of their ability in math predicted later math achievement, while their self-concept of their ability in reading predicted later reading achievement.


The finding suggests that the links between self-concept of ability and later achievement are specific to domains; that is, there is a link from students' self-concept about reading to reading achievement Nike Air Max Soldes France Pas Cher , and from students' self-concept about math to math achievement.


Self-concept is how students perceive their capabilities to succeed on academic tasks.


The study also showed that success was not limited to students who perform at the top levels.


"It extends to students with different levels of achievement in math and reading," said Maria Ines Susperreguy, assistant professor at Pontificia Universidad Catolica de Chile, who led the study.


"Even the lowest-performing students who had a more positive view of their math and reading abilities had higher levels of achievement in math and reading."


Researchers will further investigate into what parents or students did to have created these beliefs.


The study has been published in the latest issue of Child Development.
