CANBERRA, May 10 (Xinhua) -- Technology may have a harmful effect on children's development and creativity, Australia's report found on Tuesday.The Pilot Pen Australia Creativity Report found that children could be depending too much on technology such as computers.Written by psychologist Kimberley O'Brien, the report suggested that students are becoming scared of handwritten tasks as there is no spelling or grammar check tool to pick up their mistakes as they go along."Children who develop this kind of dependency on computer software are less likely to write using a pen and paper given that they will feel a vulnerability to failure," the report said.It said using software that immediately tells children to correct errors like spelling and grammar could disrupts their thought patterns and stunts their ideas, and children who hand write are able to produce almost twice as many ideas as those using computer technology to write a creative story.The report studied 300 Year five and six children, and found handwritten essays were completed significantly faster and contained a higher standard of sentence structure, grammar, punctuation, cohesion, ideas development and organization than those completed using keyboards.A further study found students in Years two, four and six produced up to twice as many ideas writing on pen and paper as those on computers.O'Brien said the results were due to computers putting extra pressure on writers to edit as they go rather than get their ideas down first and edit minor mistakes later.O'Brien said children were most likely to develop their handwriting skills between the ages of eight and 10, and she urged all teachers and parents to ensure their children met community standards for legible handwriting.However, she said that computers are a good support tool, and they should not replace handwriting entirely.

WASHINGTON, May 20 (Xinhua) -- Two U.S. astronauts conducted the first of four spacewalks for space shuttle Endeavour's STS-134 mission on Friday morning, the U.S. National Aeronautics and Space Administration (NASA) said.According to the U.S. space agency, Endeavour's mission specialists Andrew Feustel and Greg Chamitoff completed the six-hour, 19-minute spacewalk at 9:29 a.m. EDT (1329 GMT). They successfully installed antennas for the External Wireless Communication system, routing cables, setting up the antenna, installing handrails, and connecting power cables.Because of a carbon dioxide sensor failure in Chamitoff's spacesuit, flight controllers limited his spacewalk time to about six hours 20 minutes, 10 minutes less than the planned six hours and 30 minutes. There was no indication his suit's carbon dioxide levels would rise. However, they deferred tasks to remove a micrometeoroid debris shield to access and attach some of the connection points.This was the 245th spacewalk conducted by U.S. astronauts. It was Feustel's fourth spacewalk for a total time of 27 hours and 17 minutes, and Chamitoff's first.Endeavour lifted off on Monday morning from Kennedy Space Center in Florida, to deliver to the International Space Station a 2-billion-dollar, multinational particle detector known as the Alpha Magnetic Spectrometer (AMS).AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.

CAPE TOWN, April 30 (Xinhua) -- The World Economic Forum on Africa, scheduled on May 2-4 in Cape Town, South Africa, will see participants exchange views on how the continent can turn to the next chapter of development.The meeting, expected to gather a record 900 participants from over 60 countries, will be held under the theme "From Vision to Action, Africa's Next Chapter," organizers said."We chose this theme because we feel it is very relevant for the events that are taking place on this continent, and the opportunity for growth and investment that the international and African communities are seeing," said Katherine Tweedie, head of Africa for the World Economic Forum.Seven of the fastest growing economies in the world in the next five years will be in sub-Saharan Africa, Tweedie noted, saying that a lot of discussion will be devoted to explore drivers behind this growth.Africa's economic growth in recent years have impressed the world. Though being the most underdeveloped continent, Africa have been more resilient than expected during the global economic crisis.The International Monetary Fund (IMF) have predicted that the continent's growth in 2011 will reach 5.3 percent.Under one of the three thematic pillars, "Shaping Africa's Role in the New Reality," the meeting will explore how Africa can take on a leadership role in the new reality and guard against newly emerging global and regional risks. Participants will look at how Africa can strengthen its representation and negotiation capacity on global platforms such as COP 17 and the G20.Meanwhile, the meeting will look into Africa's industrial diversification, which is widely considered as an effective way to increase competitiveness. Discussions under the thematic pillar of "Fostering Africa's News Champions of Growth" will focus on what innovative and entrepreneurial lessons drive Africa's fastest- growing companies, and how can Africa's emerging economies build capacity in science, technology and innovation to move up the value chain.Another topic expected to attract much attention is Africa's inclusive development. In recent years, African decision makers have been looking for ways to attain inclusive development by translating economic growth into better lives for the people.Marcus Courage, managing director of consulting group Africapractice, said ahead of the meeting that Africa must start measuring its economic growth in terms of job creation and progress of value addition of what it produces, rather than the gross domestic product (GDP), if it has to move from vision to action."One of the challenges is that we measure economic success in therms of GDP. That is not fair reflection of action," he told Xinhua.Under the thematic pillar of "Building Partnership for Inclusive Development," participants will debate on how can inclusive growth be put at the heart of a sustainable development agenda for Africa, and how can government of African countries work together with the business sector to distribute more equitably the benefits from the wealth in natural resources, among others.Regarding the highlight of this year's meeting, Tweedie said there will be a strong focus on green growth and the environment agenda, working closely with the South African government, given that South Africa will be hosting the COP 17 meetings in December.The meeting will also have very strong representation from Francophone west Africa for the first time. As a result a good part of the discussions will be focusing on issues taking place in this part of Africa, she added.Although South Africa has hosted the World Economic Forum on Africa for a number of times, this year the host is attracting particular attention.South Africa has joined the BRICS group of countries which also include Brazil, Russia, India and China, becoming the only African member in the grouping. It is also the only country from Africa in G20. In November this year, South African city of Durban will host the 17th Conference of the Parties (COP 17) to the UN Framework Convention on Climate Change.How can the country speak for Africa in the international arena, and what role can it play in facilitating closer cooperation between developing countries is also expected to draw in-depth discussions at the meeting.Meanwhile, participants are also expected to exchange views on issues including Africa's agriculture development, infrastructure construction, China-Africa cooperation, impact of political situation in North African and the Middle East on Africa's economic development, among others.
