She points to the insomnia and other unpleasant symptoms of altitude sickness that humans suffer when deprived of oxygen.But the molecular mechanisms underlying the response to oxygen deprivation are not well understood. All we know about mammals is that regulation of their red-blood-cell count and other physiological responses to changing oxygen levels involve a protein called hypoxia-inducible transcription factor, which increases or decreases the expression of the genes controlling those responses. Special lessons will also be introduced to teach working skills to pupils.Students are expected to be asked to write up what they have learnt from their placements on completing them.The Qualifications and Curriculum Authority, the Government’s exams watchdog, describes the introduction of work experience as a “planned activity that uses the context of work to develop knowledge, skills and understanding, including learning through the experience of work, learning about work and working practices, and learning the skills for work”.The new drive is in addition to government plans announced earlier to allow disaffected 14 to 16-year-old pupils to spend up to three days a week out of school at college or work. “If anyone asks if it is for low achievers, the answer is a straight ‘no’ – full stop.”Ministers believe that an early introduction to working life will help recruits arriving for their first day of work to adjust to the working environment.Regional liaison committees – education business partnerships between firms and schools – have been set up to improve the quality of work experience on offer. Others will learn through part-time jobs or simulate work experience in further education colleges. It is part of a drive to dispel a growing myth that work experience is only for those pupils who are bored with the academic curriculum.”It is for high-flyers, it is for people who are disaffected, it is for everyone,” said Mike Cox, director of vocational programmes at the Learning and Skills Development Agency – which is pioneering its introduction.

All state school pupils from the age of 14 are to be compelled to do work experience from the beginning of the new term this autumn when a new national curriculum requirement comes into effect.
Almost all 14 to 16-year-old children will be placed with local firms for about two weeks. The committee remained within its stated budget and is believed to have received discounted rates, but the total cost is still likely to have been about £30,000.A spokeswoman for the committee confirmed that the MPs visited Los Angeles last month but refused to comment on where they stayed or how much the trip cost. In its submission to the Government’s review of its charter, entitled Building Public Value, the BBC outlined the problem with public service broadcasting in the US.”PBS, the sole American public service television broadcaster, is a marginal broadcaster showing minority programmes in which commercial television has no interest,” the BBC said.. In June 2003, the MPs visited the city as part of an inquiry into the British film industry. They flew British Airways business class and stayed at the Chateau Marmont hotel, a replica of an 18th- century French castle, on Sunset Boulevard.A British Airways business class return ticket costs about £2,450, while standard rate rooms at the Chateau Marmont are priced at £220 a night. The meeting with the News Corp chief was private and informal, and did not form part of the committee’s official inquiry into the renewal of the BBC’s charter.Mr Murdoch makes regular trips to Britain, where his media interests include BSkyB and News International, publisher of The Sun and The Times, but because he is a US citizen, the select committee has no power to summon him to appear before them.It is not the first time the committee has travelled to Los Angeles. It was well worthwhile.”The committee, chaired by the veteran Labour backbencher Sir Gerald Kaufman, visited more than a dozen media organisations during the visit, but the highlight was a meeting with Mr Murdoch.

The US leads the way technologically and our visit to more than a dozen companies opened our eyes to the changing nature of broadcasting. But while the committee may have tourism under its remit, let’s hope that the public cost of this trip can be justified entirely in terms of broadcasting,” he added.Members of the committee raised concerns beforehand about whether the trip was justified. Chris Bryant, the Labour MP for the Rhondda, originally opposed the visit but changed his mind.He said: “We wanted our report on the future of the BBC to be well-informed and ahead of the game. “If the US offers cutting-edge technology, as is claimed, it also offers a public service broadcasting landscape to avoid,” Mr Foster said.”The public value of getting the BBC’s Charter Review right is huge. A similar trip last year to research the British film industry cost about £30,000.The latest visit raises the question of whether California is the best place for MPs to research the future of the BBC, when the US has a dismal track record in public service broadcasting. Members of the committee argue that American firms are at the forefront of broadcasting technology and are therefore crucial to their inquiry into the BBC’s charter.Don Foster, the Liberal Democrat culture and media spokesman, said he hoped the committee could justify the expense to the taxpayer.
