CYBER bullying, a worldwide big problem

CYBER bullying has become more widespread among people today, especially with the emergence of social networking sites like Facebook and Twitter (“Vengeance via the Net” – The Star, March 21).

Social networking sites offer people the chance to jot down the happenings in their daily lives, express opinions and share ideas, besides venting their frustrations.



However, cyber bullies take it a step too far when posting nasty and derogatory comments about others. The reason for their action is that they are prejudiced towards others.

Their prejudice stems from the fact that they think that the other person is not sociable and less outspoken. Due to jealousy, cyber bullies also target those who are popular.

Their methods of bullying include stealing other’s pictures or writing unpleasant remarks in order to attract attention.

Some work in groups so that they seem powerful, and the victims have no chance to turn the tables on them.

Cyber bullies will even use electronic means to superimpose the targeted victim’s face on a nude photo to destroy that person’s reputation.

The main motive is to hurt the other party, and cyber bullies are aware of their actions.

Cyber bullies are actually craving for attention. They lack confidence and they boost their pride and ego by destroying other people’s image. They enjoy the thrill of publicly shaming others in the mistaken idea that it will make them look good.

In actual fact, they are cowards hiding behind technology and using it as a weapon to humiliate others. They do not realise that their actions can have serious consequences.

The person they hurt may be harmed emotionally and psychologically. The victims suffer in silence because they do not know where to turn to for help. It will affect their daily routine.

It is advisable that victims of cyber bullying do not retaliate but instead inform their parents or the authorities.

Cyber bullies may say they are doing it for fun, but their actions will backfire should they be caught.

They are actually the ones who are in need of help. They may even take their bullying ways to the extreme, such as physical violence, if they are not stopped.
Counselling is the proper way to handle cyber bullies. Social networking sites are good outlets to voice opinions but one should not abuse the privilege. Use it right and one can eventually lead a fulfilling life.

Are antibiotics an end to modern medicine?

A warning by the head of WHO that antibiotic resistance is so serious that it may lead to an end to modern medicine should alert health authorities to contain this most serious health crisis.

LAST week, the head of the World Health Organisation (WHO) sounded a large alarm bell on how antibiotics may in future not work anymore, due to resistance of bacteria to the medicines.

Antibiotic resistance has been a growing problem for some time now. From time to time, there will be news reports of the outbreak of diseases, old and new, that cannot be treated because the bacteria have grown more powerful than the antibiotics used against them.

And experts have been warning about how the wrong use of antibiotics has given the bacteria the opportunity to develop resistance, enabling them to become immune to the medicines.

What is needed, of course, is a multi-prong strategy to prevent the abuse and wrongful use of antibiotics. Drug companies should not over-market their products. Doctors should not over-prescribe. And antibiotics should not be used on animals that are not sick but to fatten them and thus enable higher profits.

Now, the Director-General of the WHO has given a big warning that the growing threat of resistance may mean an end to modern medicine, and the entry of the post-antibiotic era.

Speaking at a meeting of infectious disease experts in Copenhagen last week, Dr Margaret Chan said there was a global crisis in antibiotics caused by rapidly evolving resistance among microbes responsible for common infections that threaten to turn them into untreatable diseases.

Every antibiotic ever developed was at risk of becoming useless.

“A post-antibiotic era means, in effect, an end to modern medicine as we know it. Things as common as strep throat or a child’s scratched knee could once again kill. For patients infected with some drug resistant pathogens, mortality has increased by around 50%,” she said.

“Some sophisticated interventions, like hip replacement, organ transplants, cancer chemotherapy and care of pre-term infants, would become far more difficult or even too dangerous to undertake.”

Dr Chan called for action to restrict the use of antibiotics in food production. “Worldwide, the fact that greater quantities of antibiotics are used in healthy animals than in unhealthy humans, is a cause for great concern,” she said.

She called for measures — doctors prescribing antibiotics appropriately, patients following their treatments — and restrictions on the use of antibiotics in animals.

These actions have, in fact, been suggested for many years, including by the health group REACT, based in Sweden, by health networks such as Health Action International, and locally, by the Consumers’ Association of Penang.

The WHO itself has the scope to do much more in alerting health authorities and in building the capacity, especially of developing countries, to act.

There are forms of TB that have become untreatable because of multi-drug resistance. The TB pathogen has become immune to many antibiotics. This has resulted in a resurgence of the deadly disease. The story is the same for many other pathogens causing other diseases.

As Global Trends reported in June 2011, a worrying development is the discovery of a gene, known as NDM-1, that has the ability to alter bacteria and make them highly resistant to all known drugs, including the most potent antibiotics.

In 2010, there were reports of many such cases in India and Pakistan and in European countries. At the time, only two types of bacteria were found to be hosting the NDM-1 gene – E coli and Klebsiella pneumonia.

But it was then feared that the gene would transfer to other bacteria as well, since it was found to easily jump from one type of bacteria to another. If this happened, antibiotic resistance would spread rapidly, making it difficult to treat many diseases.

These concerns have been proven to be justified. In May 2011, the Times of India published an article based on interviews with British scientists from Cardiff University who had first reported on NDM-1’s existence.

The scientists found that the NDM-1 gene has been jumping among various species of bacteria at “superfast speed” and that it “has a special quality to jump between species without much of a problem”.

While the gene was found only in E coli when it was initially detected in 2006, now the scientists have found NDM-1 in more than 20 different species of bacteria. NDM-1 can move at an unprecedented speed, making more and more species of bacteria drug-resistant.

Since there are very few new antibiotics in the pipeline, when the resistance grows among the whole range of bacteria to the existing drugs, human beings will be more and more at the mercy of the increasingly deadly bacteria.

In May 2011, there was an outbreak of a deadly disease caused by a new strain of the E coli bacteria that killed more than 20 people and affected another 2,000 in Germany.

They were affected by a new strain of the already rare 0104 type of E coli. There are other common types of E coli which normally cause only a mild ailment. The WHO said the variant had “never been seen in an outbreak situation before”.

Although the “normal” E coli usually produces mild sickness in the stomach, the new strain of E coli 0104 causes bloody diarrhoea and severe stomach cramps, while in some of the more serious cases so far, it also causes haemolytic-uraemic syndrome (HUS), which damages blood cells and the kidneys.

A major problem is that the bacterium is resistant to antibiotics. Eradication of these kinds of bacteria is impractical partly because they are able to evolve so rapidly, according to medical experts.

Now that the WHO chief has sounded the alarm bell, health authorities should redouble their efforts to contain the crisis. An “end to modern medicine” and a “post-antibiotic era” are predictions too horrible to imagine.

Cyber-attacks on China

  By Phil Muncaster

China is claiming attacks on public and private organisations from outside of its borders have rocketed in the past year - from five million computers affected in 2010 to 8.9m in 2011.

Attacks on Chinese websites are on the rise, according to a government report >>

State-run newspaper China Daily reported the figures from (deep breath) the government’s National Computer Network Emergency Response Technical Team and Coordination Center.

They revealed that machines behind 11,851 IP addresses from overseas took control of 10,593 Chinese websites during 2011. Other attacks involved the destruction of servers and stealing of personal data from web users in the People’s Republic.

Some 1,116 sites were defaced by overseas attackers, and just under half of those government sites, Wang Minghua, deputy director at the centre, told a news conference on Monday.

“This shows that Chinese websites still face a serious problem from being maliciously attacked by foreign hackers or IP addresses," he is quoted as saying.

Surprisingly, Japan is alleged to be the source of most attacks on China, supposedly landing 22.8 per cent, followed by the US with 20.4 per cent and then the Republic of Korea with 7.1 per cent.

The attacks were both financially motivated and targeted at stealing sensitive information from government departments, according to the report, although tellingly there is no breakdown for each.

China has swung from being a country frequently accused of launching cyber-attacks on Western nations to one finding itself on the business end of hackers' keyboards. Although it has been frustratingly difficult for investigators and politicians to prove, everyone from Hillary Clinton to William Hague and Google’s Eric Schmidt has pointed accusing fingers at the Asian nation as a source of malicious net traffic.

Most recently, a detailed report from US defence contractor Northrop Grumman revealed that the People’s Liberation Army is tooling up with advanced information warfare capabilities, and warned that academia and commercial technology firms are helping to provide it with significant R&D resources.

However, despite the threat that Western governments believe Chinese hackers pose, it’s also likely that as China increasingly becomes an affluent web-connected nation, international cyber-criminals will look to target its web users. There are after all more than 500m users online in the People’s Republic, and almost one billion mobile subscribers, while a growing middle class is spending increasing amounts of cash online - China’s internet GDP will grow at a CAGR of over 17 per cent through to 2016, according to new research.

It would be naïve to think that the US, UK and other nations are snoozing while China-sponsored attackers target their data. The UK’s Cyber Security Strategy announced in November explained that a Cyber Defence Operations Group will be installed at the Ministry of Defence next month, for example.

Overseen by Air Marshal Sir Stuart Peach, the group will have a mission to develop "new tactics, techniques and plans to develop military cyber capabilities”.

The latest stats from the Chinese government may be slightly exaggerated but shouldn’t be dismissed out of hand. ®
