                              ARE YOU A FACEBOOK ADDICT?  

Are you a social media enthusiast or simply a Facebook addict? Researchers from Norway have developed a new instrument to measure Facebook addiction, the Bergen Facebook Addiction Scale.

"The use of Facebook has increased rapidly. We are dealing with a subdivision of Internet addiction connected to social media," Doctor of Psychology Cecilie Schou Andreassen says about the study, which is the first of its kind worldwide. 

Andreassen heads the research project  "Facebook Addiction" at the University of Bergen (UiB). An article about the results has just been published in the renowned journal Psychological Reports. She has clear views as to why some people develop Facebook dependency. 

"It occurs more regularly among younger than older users. We have also found that people who are anxious and socially insecure use Facebook more than those with lower scores on those traits, probably because those who are anxious find it easier to communicate via social media than face-to- face," Andreassen says.  

People who are organised and more ambitious tend to be less at risk from Facebook addiction. They will often use social media as an integral part of work and networking. 

"Our research also indicates that women are more at risk of developing Facebook addiction, probably due to the social nature of Facebook," Andreassen says. 

Six warning signs

As Facebook has become as ubiquitous as television in our everyday lives, it is becoming increasingly difficult for many people to know if they are addicted to social media. Andreassen’s study shows that the symptoms of Facebook addiction resemble those of drug  addiction, alcohol addiction and chemical substance addiction. 

The Bergen Facebook Addiction Scale is based on six basic criteria, where all items are scored on the following scale: (1) Very rarely, (2) Rarely, (3) Sometimes, (4) Often, (5)Very often, and (6) Always. 

• You spend a lot of time thinking about Facebook or planning to use of Facebook.

• You feel an urge to use Facebook more and more.

• You use Facebook in order to forget about personal problems.

• You have tried to cut down on the use of Facebook without success.

• You become restless or troubled if you are prohibited from using Facebook.

• You use Facebook so much that it has had a negative impact on your job/studies.  

Andreassen’s study shows that scoring “often” or “very often” on at least four of the six items may suggest that you are addicted to Facebook.

Brazil to replace oil rigs with ‘underwater cities’

Traditional oil rigs will be replaced with “underwater cities” within a decade under ambitious plans being drawn up by Petrobras, Brazil’s state-owned energy group.

A Petrobras oil platform at Guabanara bay in Rio de Janeiro.

Petrobras plans to turn science fiction into reality to extract oil from the vast pre-salt oil fields discovered off the south east coast of Brazil.
The plan is to construct ‘cities’ more than 2,000 metres under water, containing machines, giant pieces of equipment and robots that could inspect the systems being used to extract millions of barrels of oil. Many operations would be fully automated while others would be controlled by humans at a distance.
Petrobras already owns virtual reality laboratories where engineers can inspect 3D images of oil fields. But now they want to take a further technological leap by installing floating rig equipment on the sea bed.
The machinery under the sea would be capable of separating oil, gas, water and sand, compressing substances and generating enough energy to keep the operation functioning.
