United Arab Emirates (UAE) developer Emaar Properties has claimed that their Burj Dubai commercial and residential tower, currently under construction, has become the world’s tallest building, reaching a height of 512.1 metres (or 1,680 feet) and 141 storeys.

The current official record holder, Taipei 101 of Taiwan, has a height of 508 metres and 101 storeys, and will retain the “tallest building” title for some time to come. The Council on Tall Buildings and Urban Habitat sets the criteria for achieving height records for buildings, and will not evaluate the Burj Dubai until construction is complete in late 2008. Although final height details have been kept secret by the developer, the Burj Dubai is expected to reach nearly 700 metres in height, with approximately 160 storeys.

The current record holder for the world’s tallest free-standing structure is the CN Tower in Toronto, Canada. It has a height of 553 metres. The Burj Dubai, therefore, would claim both records when it is completed.

Once the Burj Dubai is completed, it will have required 330,000 cubic metres of concrete, 39,000 tonnes of steel and 142,000 square metres of glass, according to Emaar Properties. The building will have 56 lifts (elevators) that can move at a rate of speed of 1.75 to 10 metres per second.

Dubai is undergoing a construction boom currently with the Burj Dubai as the planned centrepiece of a $US20 billion project, which will eventually realize some 30,000 apartments and boast the world’s largest shopping mall.

There have been criticisms of the working conditions for construction workers in the UAE. A majority of the estimated 500,000 construction workers in the UAE are foreign workers from India, Pakistan and Bangladesh.

In a 2006 report on the UAE’s treatment of migrant workers, entitled Building Towers, Cheating Workers, Human Rights Watch documented abuses in UAE such as, “extremely low wages, several years of indebtedness to recruitment agencies for fees that UAE law says only employers should pay, the withholding of employees’ passports, and hazardous working conditions that result in apparently high rates of death and injury.”

In October of last year, Human Rights Watch delivered specific recommendations to the UAE government for improvement of working conditions. The UAE government acted swiftly on the report and put in place several improvements, which were applauded by Human Rights Watch.

However, the salaries of migrant construction workers remain in the range from $106 to $250 per month, while the national average wage is over $2,000 per month. Trade unions remain illegal in the UAE.

West Indies have beaten England by 15 runs in the first Twenty20 international of their tour of England at The Oval, London, England.

The West Indian innings started off badly by losing Gayle early, however they turned their fortunes around with some attacking and aggressive cricket and posted a huge total of 208. A bigger total could have been posted if it had not been for a late innings batting collapse. England started their reply by getting off to a flyer, but lost some early wickets that slowed down the run-rate. Leading the charge was Paul Collingwood with a fast 79 with 5 4’s and 4 6’s. In the end, England fell short by 15 runs. Had they not have lost the early wickets, England would have probably won the match to take a 1-0 lead in the series. Instead, it is West Indies that have taken a 1-0 lead in the series.

Members of the All India Bank Employees Association have threatened to go on nation-wide strikes to express their unhappiness with the move to privatise banks, allowing foreign direct investment in the banking sector and outsourcing of services. The exact dates of the strike will be decided at the AIBEA national general council meeting to be held in Chennai on June 13 and 14. Speaking to press persons on Friday, C.H. Venkatachalam, secretary of the association, condemned the attempts to continuously `attack the financial and banking sector.’

The AIBEA was against the government’s intention to privatise public sector banks and the disinvestment of shares up to 49 per cent. In the past decade, a number of private sector banks had folded and hence, in the best interests of the investor, banks should continue to remain in the public sector, he said. Merging public sector banks into five or six big banks in order to enable them become global institutions dealing with international trade and business was a `retrograde’ idea, he charged. The total assets of all the 27 public sector banks in the country (less than U.S. $300 billion) were well below the assets of any top global bank, he added.

A robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.

If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.

There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”

There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.

Investigators examining the wreck of British Airways Flight 38, a Boeing 777 that crash landed short of the runway at London’s Heathrow Airport in the first hull loss of a 777, are examining the aircraft’s fuel system as a possible factor in the crash. No-one was killed as the scheduled flight from Beijing, China lost power during final approach on January 17.

136 passengers and 16 crew were on board when power was lost to the two Rolls-Royce engines about two miles from the runway, at a height of 600 feet. Autopilot and autothrottle were engaged at the time, the latter having just commanded an increase of thrust to the engines when power was lost. Co-pilot John Coward, in control at the time, was subsequently praised for being able to glide the disabled plane to within 1,000 feet of the runway, clearing a number of houses along the way.

Subsequent investigation has revealed that not only did the engines not fail simultaneously, but neither failed completely, contradicting initial belief. A preliminary report by the United Kingdom’s Aircraft Accident Investigation Branch (AAIB) stated that after the autothrottle commanded more thrust “The engines both initially responded but after about 3 seconds the thrust of the right engine reduced. Some eight seconds later the thrust reduced on the left engine to a similar level… Both engines continued to produce thrust at an engine speed above flight idle, but less than the commanded thrust.” This situation prevailed until impact.

On Wednesday the AAIB stated that they were examining “All possible scenarios that could explain the thrust reduction and continued lack of response of the engines.” However, it also went on to specifically mention attention to the jet’s fuel system, saying “This work includes a detailed analysis and examination of the complete fuel-flow path from the aircraft tanks to the engine-fuel nozzles.” The AAIB also ruled out the plane having completely run out of fuel, stating that there was “adequate fuel” in the tanks when the plane crashed. In addition to the fuel required to get to the target destination or emergency alternative airport – whichever is further – aircraft typically carry between thirty and forty-five minutes worth of extra fuel as a safety margin.

Possible scenarios being examined include fuel contamination, coming either from fuel taken on at Beijing or leakage from an unknown source. In particular, a heavy contaminant at the bottom of the tanks would explain a lack of earlier problems on the flight, as the fuel levels would only have become low in the final stages of the trip. Another possibility is that a central part of the fuel system developed a leak, reducing the amount of fuel available to the engines.

It is known that, according to the AAIB, “the autothrottle and engine-control commands were performing as expected prior to, and after, the reduction in thrust,” suggesting that all software in the aircraft was functioning correctly and rendering a software failure unlikely, although this possibility also remains under investigation.

Tuesday, March 15, 2005A federal jury found Bernard Ebbers guilty on all nine counts in an indictment for fraud, conspiracy and false regulatory filings. The verdict was handed down by a New York jury after 8 days of deliberation on the former WorldCom CEO and mastermind behind the accounting scandal that brought down the telcom giant.

AP writer Erin McClam reported that when the verdict was announced, “Ebbers’ face reddened.”

Sentencing is set for the second Tuesday of next week when he could receive 85 years in prison for the conviction.

Ebbers who took the stand in his own defence, said he left the details of the company’s accounting to others and that he had no knowledge of shady practices. But Scott Sullivan, the ex-chief financial officer of the company and key prosecution witness, directly linked Ebbers to the fraud. Sullivan agreed to co-operate with prosecutors in the hopes of receiving a lenient sentence for his own involvement in the scandal.

The fall of WordCom sparked a massive class action law suit by investors. The plunge in WorldCom’s stock changed the capitalized value of the company in the range of $11 billion as the scandal unravelled. Secuities fraud cases stemming from the suits will probably break new legal ground where the involvement of investment banks and public accounting firms who would normally check company irregularities will be called into legal question.

The president of Egypt has suffered a “devastating blow” after the country’s army announced they would not use force against their own people, who continue to protest against the government tonight. The news came hours after six journalists who reported on the protests were released from custody.

Hosni Mubarak yesterday announced a new cabinet, which does not include several figures who protesters largely do not approve of. Analysts have, however, suggested little had changed within the government; many positions, they say, are filled with military figures.

In a statement broadcast on state media in Egypt, the army said: “To the great people of Egypt, your armed forces, acknowledging the legitimate rights of the people … have not and will not use force against the Egyptian people.” A BBC correspondent in Cairo said the announcement meant it “now seems increasingly likely that the 30-year rule of Mr Mubarak is drawing to a close.”

“The presence of the army in the streets is for your sake and to ensure your safety and wellbeing. The armed forces will not resort to use of force against our great people,” the statement added. “Your armed forces, who are aware of the legitimacy of your demands and are keen to assume their responsibility in protecting the nation and the citizens, affirms that freedom of expression through peaceful means is guaranteed to everybody.”

Earlier today, six journalists from the independent news network Al-Jazeera were released from custody after being detained by police. The U.S. State Department criticized the arrests; equipment was reportedly confiscated from the journalists.

Egyptian officials yesterday ordered the satellite channel to stop broadcasting in the country. Al-Jazeera said they were “appalled” by the government’s decision to close its Egyptian offices, which they described as the “latest attack by the Egyptian regime to strike at its freedom to report independently on the unprecedented events in Egypt.”

In a statement, the news agency added: “Al-Jazeera sees this as an act designed to stifle and repress the freedom of reporting by the network and its journalists. In this time of deep turmoil and unrest in Egyptian society it is imperative that voices from all sides be heard; the closing of our bureau by the Egyptian government is aimed at censoring and silencing the voices of the Egyptian people.”

On Friday, Wikinews reported the government had shut off practically all Internet traffic both out of and into the nation, as well as disrupting cellphone usage. A spokesperson for the social networking website Facebook said “limiting Internet access for millions of people is a matter of concern for the global community.”

A reported 50,000 campaigners, who are demanding the long-time leader step down and complaining of poverty, corruption, and oppression, filled Tahrir Square in Cairo today, chanting “We will stay until the coward leaves.” It is thought 100 people have so far died in the demonstrations. Today there have been protests in Suez, Mansoura, Damanhour, and Alexandria.

Speaking to news media in the area, many protesters said the new cabinet did little to quell their anger. “We want a complete change of government, with a civilian authority,” one said. Another added: “This is not a new government. This is the same regime—this is the same bluff. [Mubarak] has been bluffing us for 30 years.”

In Tahrir Square today, protesters played music as strings of barbed wire and army tanks stood nearby. Demonstrators scaled light poles, hanging Egyptian flags and calling for an end to Mubarak’s rule. “One poster featured Mubarak’s face plastered with a Hitler mustache, a sign of the deep resentment toward the 82-year-old leader they blame for widespread poverty, inflation and official indifference and brutality during his 30 years in power,” one journalist in the square reported this evening.

The Creative Archive project is a BBC led initiative which aims to make archive audio and video footage available to be freely downloaded, distributed, and ‘remixed’. The project is still in a pilot stage, and is only available to UK residents, but the long-term future of the project could have a major impact on the way audiences interact with BBC content.

The project is partly inspired by the Creative Commons movements, and also by a general move within the BBC to be more open with its assets. Additionally, educational audiences such as schools have expressed an interest in using BBC content within the classroom, both to watch and to create multimedia content from.

So far, clips made available under the licence have included archive news footage, nature documentary footage, and video clips content designed for educational uses. “It’s done very well with the audiences we’ve directed them towards – heavy BBC users,” says Paul Gerhardt, project leader. Users downloading the clips are also prompted to fill in a questionnaire, and so far 10-15% of people seem to be doing something with the material, although the BBC can’t be sure what exactly that is.

One of the biggest limitations within the licence as it currently stands during the pilot scheme is that the material is only available for use by people resident in the UK. The BBC’s Creative Archive sites use ‘geo-IP filtering’ to limit downloads to the UK, but there is some confusion over whether people who create their own content using the material can upload their creations to their own websites. A question within the FAQs for one of the more recent selections of clips suggests that this isn’t possible, saying “during this pilot phase material released under the terms of the Creative Archive Licence cannot be used outside the UK – therefore, unless a website has its use restricted to the UK only, content from the ‘Regions on Film’ archive cannot be published on it.”

“We want people to make full use of this content, whether they cut and paste it or whether they share it, and we completely accept that we’ve got a bit of a contradiction at the moment by saying UK-only and yet encouraging people to put it on their sites to share it with others, because you can’t expect people to have geo-IP restriction technology,” admits Mr Gerhardt. “We’re thinking hard about how to deal with this after the pilot – at the moment it’s quite likely that we’re probably going to need to find a distribution partner outside of the UK, so that if you’re outside of the UK you’ve got roughly the same experience as in the UK, but the content could be surrounded by sponsorship messages or advertising or whatever. Once we’ve done that then leakage from one to the other won’t really matter very much.”

The Creative Archive project has not been without critics from the commercial sector, worried that the BBC giving away their content for free would make it difficult for them to be able to make money from their own content. The BBC has explained to some of the commercial players that the content would be limited during the pilot, would not be available in broadcast quality, and that watermarking technologies would be trialled so that content could be recognised when it crops up elsewhere. The BBC is also investigating a business model for the future where there would be a “close relationship between public access to low-resolution content and a click through to monetising that content if you want to buy a high-resolution version”. People who want to play around with the material might discover they have a talent and then find they need to get a commercial license to use it properly, Mr Gerhardt explains, and the project wants to make it easy for this to happen.

Before the project can go ahead with the full scale launch, it will have to go through a ‘public value test’ to assess its overall impact on the marketplace, and commercial media companies will have a chance to input at this point.

For ease in clearing the rights, all of the content available under the pilot project is factual, but in the future the project could include drama and entertainment content. The BBC may also, in the future, work the Creative Archive licences into the commissioning process for new programmes. “This raises some really interesting ideas – if you have a documentary series, you could use the Creative Archive to release the longer form footage, for instance – that would create a digital legacy of that documentary series,” Mr Gerhardt explains. “The other interesting thought in the longer term would be for the BBC, or another broadcaster, to contribute to a digital pool of archive material on a theme, and then invite people to assemble their own content out of that. We could end up broadcasting both the BBC professionally produced programme accompanied by other programmes that other people had made out of the same material.”

One of the ways that the Creative Archive licence differs from the other ‘copyleft’ licences like Creative Commons, aside from the UK-only limitation, is that the licence currently allows the BBC to update and modify the licence, which may worry those using the licence that their rights could suddenly become more restricted. “The licence at the moment is a draft, and we’ve given warning that we may well improve it, but we wouldn’t do that more than once or twice. The ambition is that by the time we scale up to the full service we would have a fixed licence that everyone was comfortable with, and it wouldn’t change after that.”

“The ambition is to think about creating a single portal where people can search and see what stuff is out there under the same licence terms, from a range of different suppliers. The idea is that if we can create something compelling like that, we will attract other archives in the UK to contribute their material, so we’d be aggregating quite a large quantity.”

The Creative Archive project has captured the interest of many Internet users, who are growing increasingly, used the idea of being able to ‘remix’ technologies and content. Some groups have been frustrated with the speed at which the project is developing though, and with some of the restrictions imposed in the licence. An open letter to the BBC urges the dropping of the UK-only limitation, the use of ‘open formats’, and to allow the material to be usable commercially.

Mr Gerhardt has publicly welcomed debate of the licence, but makes it clear to me that the whole BBC archive will never all be available under the Creative Archive terms. “We will make all our archive available, under different terms, over the next five to ten years, at a pace to be determined. There would be three modes in which people access it – some of the content would only be available commercially, for the first five year or so after broadcast, say. The second route is through a ‘view again’ strategy where you can view the programmes, but they’d be DRM-restricted. And the third mode is Creative Archive. Over time, programmes would move from one mode to another, with some programmes going straight to the Creative Archive after broadcast.”

Others who disagree with the ‘UK-only’ restriction within the licence include Suw Charman, from the Open Rights Group, who has said “it doesn’t make sense in a world where information moves between continents in seconds, and where it is difficult for the average user to exclude visitors based on geography.” On the project generally, though, she said “I think that it is a good step along the way to a more open attitude towards content. It is a toe in the water, which is far preferable to the attitude of most of the industry players, who are simply burying their heads in the sand and hoping that lawsuits and lobbying for new legislation will bolster their out-dated business plan.”

Other organisations currently participating in the Creative Archive scheme include the British Film Institute, the Open University and Teachers’ TV. Two artists have been awarded scholarships to create artworks using BBC archive material, and BBC Radio 1 has held a competition asking people to use the footage in creative ways as backing visuals to music. The process of making the BBC’s archive material fully available may be a long one, but it could end up changing the way that people interact with the UK’s public service broadcaster.
