The study noted that storing electrical energy more quickly than current electrodes is important for future applications in portable electronics and electric vehicles.
“Developing new materials holds the key to lighter, cheaper and safer batteries, including for electric vehicles which will help cut carbon emissions,” added Islam in a paper published in the journal Nature Communications. (IANS)
New Delhi, November 6, 2017: Film, as one understands, is the basis of all motion pictures and both the most persuasive and pervasive form of communication in the contemporary world. Following the development of technology, films have become much more ubiquitous and accessible. It is quite apparent that films have a lot more to them than just the purpose of entertainment. Not just a communicator of ideas, a film is also a crucial pedagogical tool that facilitates learning, spreads awareness, and motivates participation from the audiences. It is an efficient medium to help audience rethink their place in the world and to encourage them to do something for good.
Noting how influential films are as a medium of communication, the topic that
always remains hot is Censorship.
Censorship is not something that can easily be placed in the category of good or bad, in fact, both its supporters and those against it, have broken their necks to justify their arguments.
Films can change attitudes, inspire people and influence them in the deepest of ways. This was recognized long ago when the 1925 Russian film, Battleship Potemkin, was banned across the world as its story and visualization were deemed so powerful that it had the potential to arouse social outrage.
The Central Board of Film Certification (CBFC) takes charge of Censorship in India. The board commands directors to remove everything it deems as offensive, on a regular basis. The CBFC has failed to convince a large audience with the reasons that it provided for the ban of certain films in India. One of these films is “Lipstick under my Burkha” which is the most recent film to become extremely popular for its ban in India. The reason that CBFC gave for the denial of certification to the film was that it is “Lady oriented”, which apparently, none can consider to be valid. If stifling the voices of women can be justified under the name of censorship, the very idea of it is threatening and must not be entertained.
Udta Punjab was also in limelight for the 94 cuts that CBFC demanded in the film, some of which included removal of the names of Punjab cities, the name of the state itself and the name of a dog which was called Jacky chain. There are many other films where the grounds on which the Censor board asked the filmmakers to cut scenes are unacceptable and sometimes plain hilarious. “Phillauri” makers were asked to mute Hanuman Chalisa as it failed to shoo the ghosts off.
The argument that the supporters of censorship usually give is that it is only in a perfect world, where children wouldn’t be exposed to films inappropriate for their age, where every person recognizes the boundary between film and reality, would censorship not be necessary; but the fact is that we don’t live in a perfect world. Censorship, as they call it, is just the step to protect the vulnerable in the society.
The people against censorship, however, shrug this idea off, and do not hesitate to call censorship in India, an incentive for the people in power to stay in power.
In principle, government holds a responsibility to make the art accessible to whoever is interested. However, with a country as diverse as ours, both absolute freedom and strict censorship could be problematic. The heterogeneity of citizens suggests the varying needs, sensibilities, attitudes and therefore, one needs to strike a balance.

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.
