Nearly Half of the Teenagers in the US and Japan are ‘Addicted’ to Smartphones, Says New Report

Nowadays, one of the worst things that can happen to us is, like, 'Oh, I left my phone at home,'

California, October 12, 2017 : About half of teenagers in the United States and Japan say they are addicted to their smartphones.

University of Southern California (USC) researchers asked 1,200 Japanese about their use of electronic devices. The researchers are with the Walter Annenberg School for Communications and Journalism. Their findings were compared with an earlier study on digital media use among families in North America.

“Advances in digital media and mobile devices are changing the way we engage not only with the world around us, but also with the people who are the closest to us,” said Willow Bay, head of the Annenberg School.

The USC report finds that 50 percent of American teenagers and 45 percent of Japanese teens feel addicted to their smartphones.

“This is a really big deal,” said James Steyer, founder of Common Sense Media, an organization that helped with the study. “Just think about it, 10 years ago we didn’t even have smartphones.”

Sixty-one percent of Japanese parents believe their children are addicted to the devices. That compares to 59 percent of the American parents who were asked.

Also, more than 1-in-3 Japanese parents feel they have grown dependent on electronic devices, compared to about 1-in-4 American parents.

Leaving your phone at home is ‘one of the worst things’

“Nowadays, one of the worst things that can happen to us is, like, ‘Oh, I left my phone at home,’” said Alissa Caldwell, a student at the American School in Tokyo. She spoke at the USC Global Conference 2017, which was held in Tokyo.

A majority of Japanese and American parents said their teenagers used mobile devices too much. But only 17 percent of Japanese teens agreed with that assessment. In the United States, 52 percent of teens said they are spending too much time on mobile devices.

Many respond immediately to messages

About 7-in-10 American teens said they felt a need to react quickly to mobile messages, compared to about half of Japanese teens.

In Japan, 38 percent of parents and 48 percent of teens look at and use their devices at least once an hour. In the United States, 69 percent of parents and 78 percent of teens say they use their devices every hour.

Naturally, that hourly usage stops when people are sleeping, the researchers said.

The devices are a greater cause of conflict among teens and parents in the United States than in Japan. One-in-3 U.S. families reported having an argument every day about smarthphone use. Only about 1-in-6 Japanese families say they fight every day over mobile devices.

Care more about devices than your children?

But 20 percent of Japanese teens said they sometimes feel that their parents think their mobile device is more important than they are. The percentage of U.S. teens saying they feel this way is 6 percent.

In the United States, 15 percent of parents say their teens’ use of mobile devices worsens the family’s personal relationships. Eleven percent of teens feel their parents’ use of smarthphones is not good for their relationship.

The USC research was based on an April 2017 study of 600 Japanese parents and 600 Japanese teenagers. Opinions from American parents and teenagers were collected in a study done earlier by Common Sense Media.

Bay, the Annenberg School of Communications dean, said the research raises critical questions about the effect of digital devices on family life.

She said the cultural effects may differ from country to country, but “this is clearly a global issue.” (VOA)

New Delhi, October 11, 2017 : Leading e-commerce portal Amazon was taken for a ride by a 21-year-old youth who is said to have duped the company for over 50 lakh.

As per the police, the accused, identified as Shivam Chopra, bought over 166 expensive mobile phones via the online e-commerce store Amazon and consequently demanded refunds claiming he had received an empty box.

Shivam, a resident of north-west Delhi’s Tri Nagar, holds a degree in hotel management. However, he chose to use all his management skills to con the commercial giant, Amazon.

A complaint registered this year on behalf of Amazon Seller Services Private Limited first raised eyebrows in June when it was revealed that refunds had been claimed for as many as 166 mobile phones that had been ordered between April and May, on the claims that the delivery packages were empty. Suspicion gathered momentum when it was further revealed that payments for all these 166 mobiles were made through gift cards.

Allegedly, Shivam would use different customer accounts (reports suggest he used 48 different accounts) to place orders of expensive phones on Amazon and would provide the portal with a false address. He would then speak with the delivery associate and collect his order at a mutually decided place within the locality. Consequently, Shivam would then place complaints with Amazon, claiming that he had received an empty package and would demand a refund.

Subsequently, refunds were initiated in the form on gift cards.

Following an enquiry, a case was registered with the Delhi Police in August.

The accused was then identified with the help of Amazon’s delivery persons, and the locals and by tracing the multiple numbers that were used to place the orders and Shivam was arrested on October 6.

According to the police, Shivam allegedly also purchased 150 pre-activated SIM cards to place the orders from different numbers. His accomplice in the con, Sachin Jain, has also been arrested, who helped provide him the SIM cards.

As per a report by PTI, upon investigation, the Delhi Police recovered 19 mobile phones from Shivam’s house. It was revealed that he had sold all other devices to buyers in the notorious Gaffar Market, or on the online marketplace OLX. The police also recovered Rs 12 lakh in cash, 40 bank passbooks and cheques from his house.

An Amazon India spokesperson later thanks ed the Delhi police for their services in an official statement and added, “We continue to work closely with the Delhi Police and thank them for all their efforts in the investigation.”

An ordinary guy who duped an e-commerce website and claimed refunds running into lakhs of rupees – the case is not a first of its kind. Previously, con-men had been arrested for duping rival e-commerce website FlipKart. However, what is peculiar is how no action has been taken to keep such frauds at bay and these cases continue to suffer.

Warning Signs of Radicalization : Understanding What Makes a Terrorist

The internet is an irrefutable aspect of modern life. But do you know what your child is doing online?

Radicalization
What motivates children to join terrorist outfits and participate in extremist activities? Pixabay
  • Radicalization is the process by which young individuals are introduced to a blatantly ideological message that accompanies extreme views
  • Over 50 per cent of the radicalization operations carried out by terrorist organizations are conducted over the internet
  • Parents must observe any change in their child’s behavior to gauge potential radicalization

New Delhi, September 4, 2017 : Imagine looking at a video of adolescents in camouflage, wearing ISIS bandanas in a barren dessert, learning hand-to-hand combat. Imagine ISIS fighters wielding long daggers standing behind them, wearing black scarves that mask their faces.

Imagine watching these masked men address the government; they claim that the government is no longer fighting an insurgency but an entire army of young adolescent recruits- kids who should have stayed in school.

ISIS has made shocking progress in expanding its operations in recent times due to the upsurge in enthusiasm that would-be jihadist from all parts of the globe demonstrate to join their fight in Iraq and Syria.

However, one of the most frequently asked questions about terrorism traces the very root of the matter.

Why do children join terrorist outfits and participate in extremist activities?

The ISIS runs an elaborate operation that targets, manipulates and eventually recruits young people to believe and uphold their twisted ideologies- a process understood as radicalization.

 

What is radicalization?

According to a report published by the Royal Canadian Mounted Police (RCMP) in 2009, radicalization is understood as the process by which young individuals are introduced to a blatantly ideological message that accompanies extreme views.

While radicalization is not always negative, it becomes problematic when it culminates into acts of violence, a phenomenon common to organizations like ISIS, IRA and Al Qaeda.

Over 50 per cent of their radicalization operations are conducted over the internet- a space flocked and dominated by young, impressionist minds.

 

Online risk of radicalization

According to John Horgan, a psychologist at UMass- Lowell who specializes in terrorism, terrorist organizations like Al Qaeda, and ISIS can be viewed as amateur psychologists, who are also adept marketers. They provide youngsters, usually very young people, with a ‘one time offer’ and encourage them to act fast.

These extremist organizations make use of internet and the social media to communicate and spread their messages, and recruit people to join their forces.

In an attempt to brainwash and lure young individuals to join forces, their messages usually present extremist vision as an exciting alternate to the ‘mainstream’.

Who are most vulnerable to radicalization?

Personal attributes or local factors can make an individual more susceptible to extremist influence. An absence of a positive, supportive force can additionally accelerate the process of radicalization.

  • Children struggling with independent identity

Some children can have a hard time accepting the culture they practice, which can make them question their place in the society. Young children tend to struggle establishing a sense of independent identity which often makes them vulnerable to extremist influence.

  • Personal circumstances

Instances in a child’s personal life such as fights within the family, or undergoing any trauma can increase their vulnerability to radicalization. Extremists prey on children with low-self esteem, who harbor feelings of injustice, such as those who believe they have been subjected to racial discrimination.

Additionally, kids who feel detested by their peers or abandoned by their family members are also at a greater risk of harboring feelings of vengeance that can motivate them to indulge in extremist behavior.

  • Emotional response

Kids who seek adventure and excitement tend to indulge in activities just for the adrenaline rush, without thinking about the consequences. Additionally, kids who yearn to dominate or control others and those who are comfortable with violence can also be an easy target for radicalization.

  • External factors

A child can also be influenced by what he experiences in the local community, country or when exposed to people who have joined any extremist group.

  • Criminal background

Individuals with a previous criminal background or those who find it difficult to integrate with the mainstream society after serving sentence in a jail, or a reprimand home may also be at a greater risk.

  • Exposure and indulgence with technology

Additionally, kids who spend increasing amount of time online, or have no supervision on their online interaction are at a greater risk.

Signs of Radicalization

There is no single route to radicalization- it can either occur quickly, or over a long period. Sometimes, there can be clear warning signs that can intimidate you when a child acts out of character. But, sometimes, these changes may not be very obvious,

  • Change in appearance and personal relationships

Young individuals may distance themselves from people, bring a significant change in their appearance and dressing style and refrain from activities that were previously a part of routine.

  • Change in political orientation

The children may exhibit sudden indulgence in a particular behavior or growing interest in politics especially relating to trouble areas. They may additionally become intolerant to those who do not share the same beliefs as them (other religions, races and ethnicity) and may begin to look down upon them.

  • Change in online identity

A change in the online identity of the individual such as changing their username on various social media accounts or the profile picture. Alternately, the individual may make two parallel profiles- one being the ‘normal’ one and the other used for extremist purposes, more often than not with a pseudonym.

Spending long hours on the internet, being secretive and showing reluctance to divulge personal details and information about their whereabouts also comprise suspicious behavior.

  • Additional signs can also include a growing fondness, sympathy or justification for extremist ideologies, increasing interest in accessing more extremist material online, being in contact with extremist recruiters or jihadis, etc.

Exhibition of one of these signs does not necessarily mean that a child is being radicalized. They can also point out to other issues that a child might be facing, such as depression.

At the heart of it all is – COMMUNICATION.

Talking to children regularly and honestly is the best way to keep them safe. Making sure that the individual is safe online is also of equal importance.

An individual undergoes several changes during adolescence that can either make children react in different ways. As a parent, you should try and recognize these changes and trace their roots. Also, we would suggest addressing all issues, rather than simply ridiculing or ignoring them.
