Info that kids share on Facebook a matter of concern: Kiwi watchdog

Wellington, May 3 (ANI): A Kiwi watchdog has revealed that there is a growing concern about the information children share on the Internet.

A Privacy Commission survey revealed that nearly 45 percent of Kiwis have online profiles, most on Facebook, and that more than half think that online social networking sites are private.

But the rush to social networking, which is up from 32 percent last June and 14 per cent in August 2007, coincides with greater concerns over online privacy, especially for children.

Privacy Commissioner Marie Shroff said that a surprising number of people, 57 percent, believed social networking sites were mostly private spaces.

She said there was an illusion of privacy on sites such as Facebook, Twitter or Flickr, but personal details or pictures could be easily accessed by anyone.

A high percentage of social network users were children, and Shroff encouraged vigilance in protecting them on the Internet.

“The internet offers a huge amount in terms of entertainment, education and ability to communicate with others, but there are risks too,” the New Zealand Herald quoted her as saying.

“When children are online they can and do give away a lot of information about themselves, without necessarily being aware of the consequences,” she explained.

Shroff cited cases of identity theft of children as young as 10 which resulted in online abuse on Facebook.

“Children can risk themselves and their families by revealing personal and intimate information, which enables harms such as identity crime, stalking, text bullying and invasion of privacy in various ways,” she stated.

In a survey by the Internet safety organisation Netsafe, 25 percent of secondary school students said they had been aggressively sexually solicited online.

Children sharing personal details online were the greatest concern among people surveyed by the Privacy Commissioner”s office, 88 percent said they worried about the information their children revealed online.

Seventy-nine per cent were concerned about the security of personal information held by overseas businesses.

Netsafe operations manager Lee Chisholm said any personal information put online should be considered public and permanently accessible.

Even if a user had tight privacy settings on a social network, messages or pictures could be relayed by friends and could resurface years after being posted.

Netsafe had observed some encouraging patterns in children”s Internet use, she said.

“Young people are quite savvy about keeping knowledge online,” she stated.

Abuse and harassment did happen, but using social networking sites “is not as big a risk as adults tend to think it is”.

The Privacy Commissioner”s study found 86 percent of users said they knew how to protect their privacy by changing settings, and 66 percent said they had altered their privacy settings.

The commissioner added that Internet users should, if necessary, put pressure on internet giants such as Google and Facebook to protect their privacy.

Both sites have been criticised internationally for privacy breaches or not guaranteeing users” safety.

Last month, Shroff wrote a formal complaint to Google after it introduced its Buzz social network, accusing it of commercially experimenting on New Zealanders.

Information technology commentator Peter Griffin said privacy rights would be increasingly strained as Internet giants tried to make social networks profitable by using targeted advertising.

He cited Facebook chief executive Mark Zuckerberg”s recent observation that the age of privacy was over.

Shroff recommended that people could use the resources on Internet safety available through Hector”s World, Netsafe and the Privacy Commissioner”s website.

The privacy survey also showed the organisations most trusted in holding personal information were health service providers, with a 94 percent confidence rating.

This was followed by the police on 88 percent, Inland Revenue on 84 percent and ACC on 68 percent.

The Law Commission is reviewing the Privacy Act. It says rapid advances in technology have challenged rights to privacy. (ANI)

Our nostrils share a ‘smelly’ rivalry

Washington, Aug 21 (ANI): Our nostrils may look like a happy pair, but according to a new study, when they pick up conflicting scents, the nose holes become deadly rivals.

The study, published online in Current Biology, a Cell Press publication, explains that when the nose encounters two different scents simultaneously, the brain processes them separately through each nostril in an alternating fashion.

The finding by researchers at Rice University in Houston is the first demonstration of “perceptual rivalry” in the olfactory system.

“Our discovery opens up new avenues to explore the workings of the olfactory system and olfactory awareness,” said Denise Chen, assistant professor of psychology, who coauthored the research paper with graduate student Wen Zhou.

For the study, 12 volunteers sampled smells from two bottles containing distinctively different odors. One bottle had phenyl ethyl alcohol, which smells like a rose, and the other had n-butanol, which smells like a marker pen.

The bottles were fitted with nosepieces so that volunteers could sample both scents simultaneously-one through each nostril.

During 20 rounds of sampling, all 12 participants experienced switches between smelling predominantly the rose scent and smelling predominantly the marker scent. Some experienced more frequent and drastic switches than others, but there was no predictable pattern of the switch across the whole group of volunteers or within individuals.

Chen said this “binaral rivalry” between the nostrils resembles the rivalry that occurs between other pairs of sensory organs.

When the eyes simultaneously view two different images-one for each eye-the two images are perceived in alternation, one at a time. And when alternating tones an octave apart are played out of phase to each ear, most people experience a single tone that goes back and forth from ear to ear.

In the laboratory setting in which each nostril simultaneously received a different smell, the participants experienced an “olfactory illusion,” she said.

“Instead of perceiving a constant mixture of the two smells, they perceive one of the smells, followed by the other, in an alternating fashion, as if the nostrils were competing with one another. Although both smells are equally present, the brain attends to predominantly one of them at a time,” the expert added.

“The binaral rivalry involves adaptations at the peripheral sensory neurons and in the cortex,” Chen said.

“Our work sets the stage for future studies of this phenomenon so we can learn more about the mechanisms by which we perceive smells,” the expert said.

In binaral rivalry, the tug-of-war between dominance and suppression of the olfactory perception exists only in the mind of the person who smells the odors, while the physical properties of the olfactory stimuli remain unchanged, Chen said. This gives humans the rare opportunity to dissociate olfactory perception and physical stimulation. (ANI)

Jacko wanted to star in ‘Phantom Of The Opera’ movie

Washington, June 29 (ANI): Theatre impresario Sir Andrew Lloyd Webber has revealed that Michael Jackson wanted to star in the movie version of the hit musical ‘Phantom Of The Opera’.

After watching the show, which debuted in 1988, numerous times the King of Pop discussed seriously with Lloyd about starring as ‘The Phantom’ in a big screen adaptation of the hit musical.

But Lloyd Webber could not make it happen for Jackson back then, as he wasn’t ready to turn it into a film.

However, when the helmer did make the movie in 2004, he cast Gerard Butler.

“The story got to him. I think he had a connection with the lonely, tortured musician. He found the idea of somebody working through music and having a girl as a muse very intriguing – and he loved that there was illusion in the show,” Contactmusic quoted Webber as saying.

“Michael became interested in playing The Phantom himself, in a movie version of the show. We talked about it a lot, but we’d only just opened and, at the time, I felt that it was too early for it to become a film. I felt his interest in Phantom was because he was interested in doing something theatrical himself,” Webber added. (ANI)

Brit art student creates invisible car!

London, May 2 (ANI): Ever wished your car turned invisible after being caught jumping the red light? Well, an art student in the UK has actually found a way to make her four-wheel vehicle invisible.

Sara Watson, of the University of Central Lancashire, spray-painted a battered Skoda Fabia to match the car park and entrance to her art studio.

And the unique work, created as part of her drawing and image-making course at the university, looks as if the car is see through.

The 22-year-old student had been given the car from a breakers yard, and then she worked for three weeks to ensure that it camouflaged perfectly with its surroundings.

“I was experimenting with the whole concept of illusion but needed something a bit more physical to make a real impact,” The Telegraph quoted Watson, who is from Ashton under Lyne, as saying.

She added: “People have been stopping in the street to look and coming up and almost bumping into it, so it’s had the desired effect.”

Steve Jackson, owner of Recycling Lives, the firm that gave Miss Watson the car, said: “When I first saw the photos I was convinced it was something which had been done on the computer, but when you look more closely you see the effort and attention to detail she has put into it. It is just amazing.” (ANI)

Worried’ EU to send fact-finding mission to Ukraine

Luxembourg – The European Union has “every reason to be worried” about Ukraine’s political deadlock and economic crisis, EU foreign ministers meeting in Luxembourg said Monday. The EU is to organize a fact-finding mission to Ukraine aimed at establishing how the EU can help the country sliding further into the abyss, German Foreign Minister Frank-Walter Steinmeier told journalists after talks with EU counterparts.

“It is timely to explore how we can best assist the country in tackling its current difficulties,” he wrote in a joint letter with his Polish counterpart, Radek Sikorski.

Sweden’s influential foreign minister, former premier Carl Bildt, said that the EU was deeply concerned by the ongoing feud between Ukraine’s president and prime minister, which has blocked the country’s bid to bring in reforms demanded by the International Monetary Fund in return for a massive bail-out.

“There’s every reason to be worried: they have a very major economic crisis … On top of that, we have got the political divisions in the country,” he said.

The country’s inability to agree on IMF-mandated reforms is “more than regrettable, that is bordering on the dangerous for the country,” he said.

The fact-finding mission would be put together by the EU’s top diplomat, Javier Solana, in collaboration with the Ukrainian government, Steinmeier said.

Ukraine is one of six former-Soviet states which the EU has invited to join its “Eastern Partnership”, a cooperation group which will be launched at a summit in Prague on May 7.

Ahead of the launch, concerns in Europe have grown over the threat of instability in Ukraine and Moldova, the state of democracy in Belarus and unresolved conflicts in Georgia, Armenia and Azerbaijan.

Bildt said that those problems make the partnership “more needed than ever.”

“I don’t think anyone (in the EU) is under the illusion that we are entering into relations with a couple of Switzerlands,” he said. (dpa)

Harry Potter’s invisibility cloak comes closer to reality

London, May 1 (ANI): Scientists have made yet another advancement in bringing invisibility cloak closer to reality by developing a material that renders objects invisible to near-infrared light.

Previous “cloaks” had metals in their structure, which resulted in imperfect cloaking due to loss of light.

In the new study, researchers from New York’s Cornell University and the University of California at Berkeley have developed a carpet-based cloak using a dielectric – or insulating material – which absorbs far less light.

This “carpet” design was based on a theory first described by John Pendry, from Imperial College London, in 2008.

Michal Lipson and her team at Cornell University demonstrated a cloak based on the concept.

Xiang Zhang, professor of mechanical engineering at the University of California, Berkeley, led the other team.

“Essentially, we are transforming a straight line of light into a curved line around the cloak, so you don’t perceive any change in its pathway,” The BBC quoted Zang as saying.

The new material negates the distortion produced by the bulge of the object under it, bending light around it, and giving the illusion of a flattened surface.

According to Zhang, the cloak “changes the local density” of the object it is covering.

“When light passes from air into water it will be bent, because the optical density, or refraction index, of the glass is different to air.

“So by manipulating the optical density of an object, you can transform the light path from a straight line to to any path you want,” the expert said.

The new material does this via a series of minuscule holes – which are strategically “drilled” into a sheet of silicon.

“Where the holes are more dense, there is more air than silicon, so the optical density of the object is reduced,” Zhang said. (ANI)

Schizophrenics can’t be fooled by ‘hollow mask’ illusion

Washington, April 7 (ANI): A new study led by UK and German researchers has shown that schizophrenia patients can correctly see through an illusion known as the ‘hollow mask’ illusion, probably because their brain disconnects “what the eyes see” from what “the brain thinks it is seeing”.

The observations made during the study attain significance as they may help understand why cannabis users may also be less deceived by the illusion whilst on the drug.

The study – carried out by scientists at the Hannover Medical School in Germany and UCL Institute of Cognitive Neuroscience in the UK – confirms that people with schizophrenia are immune to certain vision illusions, and that they are not fooled by the ‘hollow mask’ illusion.

The researchers say that this may relate to a difference in the way two parts of their brains communicate with each other – the ‘bottom-up’ process of collecting incoming visual information from the eyes, and the ‘top-down’ process of interpreting this information.

They point out that illusions occur when the brain interprets incoming sensory information on the basis of its context and a person’s previous experience, so called top-down processing.

Sometimes this process can mean that people’s perception of an object is quite different to reality – a phenomenon often exploited by magicians.

The researchers say that their study suggests that schizophrenia patients rely considerably less on top-down processing during perception.

During the study, three-dimensional normal faces and hollow faces were shown to schizophrenia patients and control volunteers, while they lay inside an fMRI brain scanner, which monitored their brain responses.

The researchers observed that all 16 control volunteers perceived the hollow mask as a normal face, mis-categorising the illusion faces 99 percent of the time.

On the other hand, all 13 schizophrenia patients could routinely distinguish between hollow and normal faces, with an average of only six percent mis-categorisation errors for illusion faces.

Upon a brain imaging analysis, the researchers observed that in the healthy volunteers, connectivity between two parts of the brain, the parietal cortex involved in top-down control, particularly spatial attention, and the lateral occipital cortex involved in bottom-up processing of visual information, increased when the hollow faces were presented.

The schizophrenia patients did not show that connectivity change.

The researchers say that the findings indicate that schizophrenia patients have difficulty coordinating responses between different brain areas, also known as ‘dysconnectivity’, and that this may contribute to their immunity to visual illusions.

They are presently studying dysconnectivity in schizophrenia further, which will hopefully advance the scientific understanding of this disorder.

Danai Dima, Hannover Medical School, says: “The term ‘schizophrenia’ was coined almost a century ago to mean the splitting of different mental domains, but the idea has now shifted more towards connectivity between brain areas. The prevailing theory is that perception principally comprises three components: firstly, sensory input (bottom-up); secondly, the internal production of concepts (top-down); and thirdly, a control (a ‘censor’ component), which covers interaction between the two first components. Our study provides further evidence of ‘dysconnectivity’ between these components in the brains of people with schizophrenia.”

Dr Jonathan Roiser, UCL Institute of Cognitive Neuroscience, says: “Our findings also shed light on studies of visual illusions which have used psychomimetics – drugs that mimic the symptoms of psychosis. Studies using natural or synthetic tetrahydrocannabinol (THC), the ingredient of cannabis resin responsible for its psychotic-like effects, have found that people under the influence of cannabis are also less deceived by the hollow mask illusion. It may be that THC causes a temporary “disconnection” between brain areas, similar to that seen in patients with schizophrenia, though this hypothesis needs to be tested in further research.”

The study has been published in the journal NeuroImage. (ANI)

Advani dismisses idea of a Third Front government

New Delhi, Apr 3 (ANI): Bharatiya Janata Party prime ministerial candidate Lal Krishna Advani on Friday dismissed the idea of a Third Front government.

Advani claimed that the main battle was between the Congress and the BJP.

“There is no scope for a Third Front government, which does not have the support of the BJP or the Congress. It is a farcical illusion in the minds of people,” he told reporters on the sidelines of party’s manifesto-release function.

Advani claimed that the Congress was facing a sad situation as its allies were leaving it one by one.

“This was because after the Left parties abandoned it, the Samajwadi Party (SP) has also parted company so also Lalu Prasad’s Rashtriya Janata Dal (RJD) and Ram Vilas Paswan’s Lok Janshakti Party (LJP), besides the Pattali Makkal Katchi (PMK), and earlier the TRS had left it,” he added.

The BJP leader also defended his statement challenging Prime Minister Dr. Manmohan Singh and Congress President Sonia Gandhi for a live debate on television.

“Anything which helps to communicate with the electorate should not be objected to and if it leads to a two- party system, it is all better,” he added. (ANI)

DMK would welcome creation of a separate Eelam, says Karunanidhi

Chennai, Mar 30 (ANI): Dravida Munnettra Kazhagam (DMK) would welcome creation of a separate ‘Eelam’, a homeland for the Sri Lankan Tamils provided it is created by a democratic process, said M Karunanidhi, DMK president and Tamil Nadu Chief Minister.

Talking to the reporters here today, Karunanidhi said, “We will be glad if a separate Eelam is created (in Sri Lanka) by people voting for it.”

He accused the opposition parties of spreading rumours that DMK does not support Sri Lankan Tamils.

“Attempts of some opposition parties in Tamil Nadu to paint the United Progressive Alliance government at the Centre and the DMK government in the state as anti Sri Lankan Tamils would not succeed…The opposition parties are trying to create an illusion among the public that my party is against Sri Lankan Tamils,” said Karunanidhi.

Spending money gives brain the same buzz as doing drugs

London, Mar 24 (ANI): Spending money gives the same buzz as doing drugs, conclude scientists.

According to researchers, splashing money stimulates the reward centres of the brain associated with types of addictive activities.

The research also found that people tend to spend more if they have higher salaries – even if prices are correspondingly high.

Such a behaviour has been described for years by economists as the ‘money illusion’.

In the study, which was led by Professor Armin Falk of the University of Bonn, 18 volunteers undertook a series of tests looking at how their purchasing decisions varied when given different salaries and product prices.

The volunteers were provided with two salary levels, one being 50 per cent higher than the other. However, when they received the higher salary, product prices in a catalogue were also 50 per cent higher.

During the same time, the participants underwent brain scans to determine the levels of activity in a part of the brain associated with reward, the ventromedial prefrontal cortex.

A purely logical response would have been for the brain to react identically in both situations. The scientists, however, found that when people were given a nominally higher salary they felt more rewarded when spending, even though their real purchasing power was the same.

“This result means that reward activation generally increases with income, but was significantly higher in situations where nominal incomes and prices were both 50 per cent higher, which supports the hypothesis that activity in the ventromedial prefrontal cortex is subject to money illusion,” The Telegraph quoted Prof Falk, as saying

Prof Falk added: “Economists have traditionally been sceptical about the notion of money illusion, but recent behavioural evidence has challenged this view.”

The study is published in the journal Proceedings of the National Academy of Sciences. (ANI)

Designers in Delhi ready to face global meltdown

New Delhi, Mar 19 (ANI): Sales of luxury clothes have gone down as people have started feeling the pinch of the global economic downturn, but designers at the ongoing Wills Lifestyle India Fashion Week, sounded optimistic.

Designers are refusing to rein in their creativity; they are using less expensive materials to construct this year’s must-haves.

“We all as designers have to become realistic about price levels, about what the recession is asking us to do are look inwards. It has to be user friendly and it has to come at good price and that it is a responsibility that we have a design team,” said Ritu Kumar, a designer who showcased her ‘Urban Folklore’ collection.

Kumar’s collection saw an innovative use of mosaic that was inspired by the Islamic tiles, checks, ‘tussore wool’, ‘stripes’, ethnic zardozi, brocades and mothra silk washed in deep maroons, yellow, purples and mud browns.

On the other hand, designer Puneet Nanda said that it is a challenge to do good business during times of slowdown. He said that he would want to make such clothes that people would want to buy.

“I have to make clothes which are going to be so beautiful that they would have to inspire of those not wanting to spend,” said Nanda, who exhibited his collection ‘Maya’ (illusion) that aimed at courting glamour and fantasy in the form of colourful patterns.

Designers said they were adapting to the global downturn, with some opting for lesser known models as against Bollywood stars and others using economically effective material.

With 102 designers and over 175 buyers participating despite the recessionary trends, fashion week brings together the business of fashion and expert designers as well as connoisseurs of lifestyle on a common platform.

This gala event will culminate on March 23. (ANI)

New York ponzi scheme accused Madoff could spend 150 years in prison

New York, Mar.11 (ANI): Bernard L. Madoff, the man accused of defrauding people of billions of dollars while operating a vast Ponzi scheme that began at least 20 years ago, is to plead guilty to the charge on Thursday, and if he does so, he could spend at least 150 years in prison.

Madoff was charged with 11 felony counts, including securities fraud, money laundering and perjury. Under federal sentencing guidelines, those crimes would yield a life sentence for the 70-year-old trader.

The charges, made public late Tuesday, offered a few fresh details about how Madoff conducted his long-running fraud. They raised its price tag from his own estimate of 50 billion dollars to nearly 65 billion dollars, the total amount that thousands of customers were told they had in their accounts at his firm.

To sustain his fraud, the New York Times quoted prosecutors as saying that Madoff assembled an ill-trained and inexperienced clerical staff, directed them to “generate false and fraudulent documents,” told lies and supplied false records to regulators, and shuffled hundreds of millions of dollars from bank to bank to create the illusion of active trading.

The government said Madoff ordered these multimillion-dollar bank transfers in part “to give the appearance that he was conducting securities transactions in Europe on behalf of the investors, when, in fact, he was not.”

And, in an accusation that extends his crime’s shadow to the edges of the business where his brother and sons worked, prosecutors accused Madoff of using some of the money he gathered through his Ponzi scheme to support the supposedly legitimate wholesale stock trading operation that made his name on Wall Street.

Specifically, prosecutors said Madoff “caused more than 250 million dollars” he collected through his Ponzi scheme from at least 2002 through 2008 “to be directed, through a series of wire transfers, to the operating accounts that funded the operations of these businesses.”

The government also charged that he had money transferred from his firm’s London office “to purchase property and services for the personal use and benefit” of himself, his family members and his associates.

Finally, prosecutors said that Madoff – whose investors prized his steady single-digit annual returns – actually had promised select clients extraordinarily high returns, as much as 46 percent, to lure them in as investors.

Although the forfeiture laws allow the government to seize any property it can trace as the proceeds of illegal activity, investigators have so far found no sign that Madoff or anyone connected with his business has anything like that amount of money.

Madoff’s lawyers have filed a letter with the court disputing that outsize figure, saying it represents all the money ever deposited in Madoff bank accounts over the years without distinguishing either legitimate business operations or the billions that were paid out to investors as part of the Ponzi scheme.

Madoff has been free on 10 million dollar bail, but confined to his apartment, since his arrest in December. It is not clear whether the government will seek to have his bail revoked if he pleads guilty on Thursday. (ANI)

‘Brain trainers’ give the same results as doing crossword or Internet surfing

London, February 26 (ANI): Spending too much of money on “brain trainers” to maintain mental agility may not be a very good idea anymore, for a new study suggests that the benefits such gadgets provide are almost the same amount as can be obtained by doing a crossword or surfing the internet.

Experts employed by a consumer group, known as Which?, say that there is not scientific evidence to prove that brain-training devices can help improve memory or stave off the risk of illnesses like dementia.

Gadgets like the Nintendo DS, which are endorsed by actress Nicole Kidman and singer Cheryl Cole, are very popular these days.

However, the experts behind the study insist that much of the evidence supporting the claims is “weak”, and that in some cases other activities, such as playing standard computer games, can have the same effect.

The gadgets whose claims were examined by the scientific experts included Dr. Kawashima’s Brain Training, Mindfit, and Lumosity.

“If people enjoy using these games, then they should continue to do so – that’s a no-brainer. But if people are under the illusion that these devices are scientifically proven to keep their minds in shape, they need to think again,” the Guardian quoted Martyn Hocking, editor of Which?, as saying.

The members of the panel were asked to try the brain training products for a month.

One of the experts, Dr Adrian Owen, assistant director at the Medical Research Council’s cognition and brain sciences unit in Cambridge, said of the research involving one group:”If they’d been asked to play Space Invaders for a month and improved at it – as surely they would – would we have concluded this was a beneficial form of brain training? Probably not.”

Defending their research standards, Michael Scanlon, a neuroscientist from Lumosity, said: “We would never say Lumosity is proven to improve day-to-day living, but there is more and more evidence it does. We have actually conducted our own clinical trials to measure effectiveness of the product.”

Bruce Robinson, chief executive of MindWeavers, which produces MindFit, said: “If you look at the wider evidence in the field the broad conclusion is that brain stimulation is working. With the MindFit product, a study was done by an independent medical centre in Israel which supported that evidence. We are not claiming MindFit will stop Alzheimer’s.”

Nintendo said: “Nintendo does not make any claims that Brain Training is scientifically proven to improve cognitive function. What we claim is the Brain Training series of games, like playing sudoku, are enjoyable and fun. These exercises can also help to keep the brain sharp.” (ANI)

Silver-screen audio trick can smooth jerky videos on cellphones

London, Researchers suggest that an effect used since the early days of cinema to make the action appear smoother can actually help in improving our perception of jerky videos sent to cellphones.

Earlier, fast music helped to create an illusion of motion in movies that could make the action appear smoother.

The research team led by Salvador Soto Faraco at the University of Barcelona, Spain recruited 15 people and showed them films of flashing discs of light that increased or decreased in size.

When the discs flashed rapidly, they appeared to move forwards or recede.

At lower flash rates, they only appeared to move when accompanied with beeps that increased or decreased in volume, reports New Scientist magazine.

The researchers insist this shows sounds can fool the brain into seeing motion even without visual cues.

This trick can make low-frame-rate video footage transmitted over a low bandwidth seem less jumpy. (ANI)
