In multiple online comments and posts on social media, Nikolas Cruz, 19, the suspect in the Valentine’s Day high school shooting in Florida, apparently signaled his intent to hurt other people.
I want to “shoot people with my AR-15,” a person using the name Nikolas Cruz wrote in one place. “I wanna die Fighting killing…ton of people.”
As investigators try to piece together what led to the school shooting that left 17 people dead and many others wounded, they are closely examining the suspect’s social media activity, as well as other information about him.
The focus on Cruz’s digital footprint highlights a question that law enforcement, social scientists, and society at large have been grappling with: If anyone had been paying attention to his postings, could these deaths have been prevented?
The FBI was contacted about a social media post in which the alleged gunman says he wants to be a “professional school shooter.”
However, though the commenter’s username was “Nikolas Cruz” — the same name as the shooting suspect — the FBI couldn’t identify the poster, according to the Associated Press.
But what if an algorithm could have sifted through all of Cruz’s posts and comments to bring him to the attention of authorities?
Data mining on Social Media
In an era where data can be dissected and analyzed to predict where cold medicine will most likely be needed next week or which shoes will be most popular on Amazon tomorrow, some people wonder why there isn’t more use of artificial intelligence to sift through social media in an effort to prevent crime.
“We need all the tools we can get to prevent tragedies like this,” said Sean Young, executive director of the University of California Institute for Prediction Technology.
“The science exists on how to use social media to find and help people in psychological need,” he said. “I believe the benefits outweigh the risks, so I think it’s really important to use social media as a prevention tool.”
Despite the 2002 movie Minority Report, about police apprehending murderers before they act based on knowledge provided by psychics known as “precogs,” the idea of police successfully analyzing data to find a person preparing to harm others is still a far-off scenario, according to experts.
Predictive policing on Social Media
Increasingly, police departments are turning to “predictive policing,” which involves taking large data sets and using algorithms to forecast potential crimes and then deploying police to the region. One potential treasure trove of data is social media, which is often public and can indicate what people are discussing in real time and by location.
Predictive policing, however, comes with ethical questions over whether data sets and algorithms have built-in biases, particularly toward minorities.
A study in Los Angeles aims to see if social media postings can help police figure out where to put resources to stop hate crimes.
“With enough funds and unfettered data access and linkage, I can see how a system could be built where machine learning could identify patterns in text [threats, emotional states] and images [weapons] that would indicate an increased risk,” said Matthew Williams, director of the social data science lab and data innovation research institute at Cardiff University in Wales. He is one of the Los Angeles study researchers.
“But the ethics would preclude such a system unless those being observed consented, but then the system could be subverted.”
Arjun Sethi, a Georgetown law professor, says it is impossible to divorce predictive policing from entrenched prejudice in the criminal justice system. “We found big data is used in racially discriminating ways,” he said.
Using Facebook posts
Still, the potential exists that, with the right program, it may be possible to separate someone signaling for help from all the noise on social media.
A new program at Facebook seeks to harness the field of machine learning to get help to people contemplating suicide. Among millions of posts each day, Facebook can find posts of those who may be suicidal or at risk of self-harm — even if no one in the person’s Facebook social circle reported the person’s posts to the company. In machine learning, computers and algorithms collect information without being programmed to do so.
The Facebook system relies on text, but Mark Zuckerberg, the company’s chief executive, has said that the firm may add photos and videos that come to the attention of the Facebook team to review.
Being able to figure out if someone is going to harm himself, herself or others is difficult and raises ethical dilemmas but, says Young of UCLA, a person’s troubling social media posts can be red flags that should be checked out. (VOA)
Amitabh Bachchan is adored by the public for his unforgettable on-screen performances as well as his magnetic demeanour. Not only do fans love Amitabh Bachchan's outstanding performance, but the actor's heartwarming words are also highly regarded. A much moved Amitabh Bachchan, during his speech to the crowd of over 80,000 people at the Reliance Industries' annual event, said that the legacy left by Dhirubhai has had a positive impact on millions of people's lives worldwide.
When Bollywood superstar Amitabh Bachchan became bankrupt in the late 1990s, Dhirubhai Ambani stepped forward to give him financial assistance. In his speech, Bachchan remembered that Dhirubhai had sent Anil Ambani to offer him financial assistance during the crisis, which he had respectfully declined. Lenders began knocking on his door, losses mounted, and his bank account dwindled to nothing. He said, "Dhirubhai's money might have gotten me out of the problem quickly. However, I respectfully declined his offer and gradually began to find work again, which let me pay off my debt."

Later, after Bachchan had recovered from the bankruptcy, one day he was invited to an event at Dhirubhai's residence; Bachchan added, "Dhirubhai was standing and having a chat with his industrialist friends when he saw me there, he called me, firstly I felt shy even to present myself in front of such big industrialists but then, I went there, and Dhirubhai declared in front of all of them that 'This young man had fallen but managed to get back up on his own, I have a lot of respect for him because of that.' Those words of his were worth much more to me than any amount of money that he could have offered me."
It was the "Reliance Family Day" event and was attended by members of the Ambani family from all generations. The event commemorated the company's 40-year journey since its inception. It also celebrated the 85th birthday of the late Dhirubhai Ambani, RILs (Reliance Industries Limited) founder.

In comparison to adults, children are prone to getting traumatized by troubling events easily, and this makes it important for parents to help their children when the times are tough. It could be a brutal accident, an unprecedented pandemic, a violent crime, or other disasters but with the right parental support, children have a higher chance of coming out stronger from an awful situation.
Anuja Kapur, Psychologist shares few tips wherein you can assist your child when tough times comes calling:
Every child responds differently to disturbing events: What children feel about a current disaster in their life and how they react to it can come and go in waves. Children can act moody and withdrawn at times, struck with sorrow and fear at other times. There's no absolute "right" or "wrong" way to feel after a traumatic event so make sure not to dictate what your child or how your child should feel and react to the event.

Encourage your child to be transparent: Just make sure you let your child know that whatever feelings they're experiencing is normal. The unpleasantness will pass if your child opens up about it and that the phase is temporary. While many teens may be reluctant to talk about their feelings with a parent, encourage them to confide in another trusted adult such as a family friend, relative, or a counselor and teacher. It's important to talkeeven if it's not with you.

Deter your child from reliving the disturbing event: Dwelling over, watching the footage, or imagining the event can be overwhelmingly stressful for children and this stress can even block their nervous system. However, to negate such things from happening encourage activities that keep your child's mind occupied so they're not obsessive about the event. You could encourage your children to read, play games together, or simply watch an uplifting movie.

Cocoon your child with warmth: In order to reassure your child that they are safe with you and feel secure, that the worst is over your physical affection is important in making them feel safe again. Teens may try to be tough through it and avoid being held, but they still need the proximity.

Maintain routines. Establishing a predictable structure and schedule for your child's life can help to make the world seem more stable again. Try to maintain regular times for meals, homework, and family activities. Make sure your child accommodates time and space for rest, play, and fun. Keeping up with a schedule can help countercheck the obnoxious feeling of stress and worry in children about the future being dark, hopeless, and unpredictable.

Acknowledge and validate your child's concerns. The disastrous events in life may give place to unrelated fright and concerns in your child. However, understanding and accepting your child's present state is a comfort for the child. If at any point the child blames himself for the event make sure to make it clear and crisp the event was not their fault, you love them, and it's okay for them to feel upset, angry, or scared but not guilty.

Irrespective of the age of your child, it is vital for parents to offer that extra support and assistance following an unsettling event. The traumatic event may bring up unrelated fears and issues in your child. However, by accepting their thoughts and replacing their fear with your love and direction, the ominous feelings will start to fade away. Eventually, the child will be able to return to a normal and healthy life. (IANS/ MBI)

The European Commission, the executive arm of the European Union (EU), has announced plans for smartphone and other electronics manufacturers to fit a common USB-C charging port on their devices in an effort to reduce waste. In addition to phones, the rules will apply to other devices like tablets, headphones, portable speakers, videogame consoles, and cameras, reports The Verge. The decision will have a huge impact on Apple, as the company still uses its own Lightning connector to charge iPhones. The proposals only cover devices using wired, not wireless and a USB-C port is only mandatory for devices that charge using a cable.

"Chargers power all our most essential electronic devices. With more and more devices, more and more chargers are sold that are not interchangeable or not necessary. We are putting an end to that," the report quoted EU commissioner Thierry Breton as saying.
The Commission also wants to unbundle the sale of chargers from the sale of electronic devices, which it says will improve the consumers' convenience. "With our proposal, European consumers will be able to use a single charger for all their portable electronics - an important step to increase convenience and reduce waste." In addition, the Commission will require manufacturers to provide relevant information about charging performance. (IANS/MBI)
