Auto sector growth story nears end, says Tata Motors CEO

Social media platform WhatsApp assured the Supreme Court on Wednesday that it will not roll out its payment services without complying with all payment regulations and norms in the country.

A bench headed by Chief Justice S.A. Bobde and comprising Justices Indu Malhotra and Hrishikesh Roy took up the matter through video conferencing. Senior advocate Kapil Sibal, representing the social media platform, said "WhatsApp Inc makes a statement on behalf of his client that they will not go ahead with the payments' scheme without complying with all the regulations in force."

The statement was made during the hearing of a petition seeking a ban on payment through WhatsApp, as it does not conform to the data localization norms. The top court took the assurance made by WhatsApp on record.

WhatsApp made the statement during the hearing of a plea seeking a ban on its payment service, for not being in line with data localization norms.

In 2018, WhatsApp was granted a beta licence to launch its payment service, but a dedicated and separate app is yet to be launched. A petition was moved in the apex court that WhatsApp's existing model for its payments service should be declared inconsistent with the Unified Payment Interface (UPI) Scheme, as a separate dedicated app has not been offered by the company.

The petitioner NGO, Good Governance Chambers, argued that the National Payments Corporation of India (NPCI) and the Reserve Bank of India (RBI) must change its model on the lines of the UPI payment scheme, and its operations may be suspended until these conditions are met.

The apex court today asked the Centre, Facebook and WhatsApp to file their replies within three weeks and it will take up the matter thereafter. The court noted that the government may process the applications filed by WhatsApp in accordance with the law and there is no stay on the same. Facebook was represented by senior advocate Arvind Datar.

The petitioner argued that lapses have been found in relation to WhatsApp's claims of having a secure and safe technological interface for securing sensitive user data.

Melbourne, Jul 24: Home-made cloth face masks may need a minimum of two layers, and preferably three, to prevent the dispersal of viral droplets associated with Covid-19, according to a study.

Researchers, including those from the University of New South Wales in Australia, noted that viral droplets are generated by those infected with the novel coronavirus when they cough, sneeze, or speak.

As face masks have been proven to protect healthy people from inhaling infectious droplets as well as reducing the spread from those who are already infected, several types of material have been suggested for these, but based on little or no evidence of how well they work, the scientists said.

In the current study, published in the journal Thorax, the researchers compared the effectiveness of single and double-layer cloth face coverings with a surgical face mask (Bao Thach) at reducing droplet spread.

They said the single layer covering was made from a folded piece of cotton T shirt and hair ties, and the double layer covering was made using the sew method described by the US Centers for Disease Control and Prevention (CDC).

The scientists used a tailored LED lighting system and a high-speed camera to film the dispersal of airborne droplets produced by a healthy person with no respiratory infection, during speaking, coughing, and sneezing while wearing each type of mask.

Their analysis showed that the surgical face mask was the most effective at reducing airborne droplet dispersal, although even a single layer cloth face covering reduced the droplet spread from speaking.

But the study noted that a double layer covering was better than a single layer in reducing the droplet spread from coughing and sneezing.

According to the researchers, the effectiveness of cloth face masks is dependent on the number of layers of the covering, the type of material used, design, fit as well as the frequency of washing.

Based on their observations, they said a home made cloth mask with at least two layers is preferable to a single layer mask.

"Guidelines on home-made cloth masks should stipulate multiple layers," the scientists said, adding that there is a need for more research to inform safer cloth mask design.

As millions of people get hooked to online dating platforms, their proliferation has led to online romance scams becoming a modern form of fraud that have spread in several societies along with the development of social media like Facebook Dating, warn researchers.

For example, extra-marital dating app Gleeden has crossed 10 lakh users in India in COVID-19 times while dating apps like Tinder and Bumble have gained immense popularity.

According to researchers from University of Siena and Scotte University Hospital led by Dr Andrea Pozza, via a fictitious Internet profile, the scammer develops a romantic relationship with the victim for 6-8 months, building a deep emotional bond to extort economic resources in a manipulative dynamic.

"There are two notable features: on the one hand, the double trauma of losing money and a relationship, on the other, the victim's shame upon discovery of the scam, an aspect that might lead to underestimation of the number of cases," the authors wrote in a paper published in the journal Clinical Practice & Epidemiology in Mental Health.

Around 1,400 dating sites/chats have been created over the last decade in North America alone. In the UK, 23 per cent of Internet users have met someone online with whom they had a romantic relationship for a certain period and even 6 per cent of married couples met through the web.

"The online dating industry has given rise to new forms of pathologies and crime, said the authors.

The results showed that 63 per cent of social media users and 3 per cent of the general population reported having been a victim at least once.

Women, middle-aged people, and individuals with higher tendencies to anxiety, romantic idealization of affective relations, impulsiveness and susceptibility to relational addiction are at higher risk of being victims of the scam.

Online romance scams are, in other words, relationships constructed through websites for the purpose of deceiving unsuspecting victims in order to extort money from them.

The scammer always acts empathetically and attempts to create the impression in the victim that the two are perfectly synced in their shared view of life.

"The declarations of the scammer become increasingly affectionate and according to some authors, a declaration of love is made within two weeks from initial contact," the study elaborated.

After this hookup phase, the scammer starts talking about the possibility of actually meeting up, which will be postponed several times due to apparently urgent problems or desperate situations such as accidents, deaths, surgeries or sudden hospitalizations for which the unwitting victim will be manipulated into sending money to cover the momentary emergency.

Using the strategy of "testing-the-water", the scammer asks the victim for small gifts, usually to ensure the continuance of the relationship, such as a webcam, which, if successful, leads to increasingly expensive gifts up to large sums of money.

When the money arrives from the victim, the scammer proposes a new encounter.

The request for money can also be made to cover the travel costs involved in the illusory meeting. In this phase, the victim may start having second thoughts or showing doubt about the intentions of the partner and gradually decide to break off the relationship.

"In other cases, the fraudulent relationship continues or even reinforces itself as the victim, under the influence of ambivalent emotions of ardor and fear of abandonment and deception, denies or rationalizes doubts to manage their feelings," said the study.

In some cases, the scammer may ask the victim to send intimate body photos that will be used as a sort of implicit blackmail to further bind the victim to the scammer.

Once the scam is discovered, the emotional reaction of the victim may go through various phases: feelings of shock, anger or shame, the perception of having been emotionally violated (a kind of emotional rape), loss of trust in people, a sensation of disgust towards oneself or the perpetrator of the crime and a feeling of mourning.

"Understanding the psychological characteristics of victims and scammers will allow at-risk personality profiles to be identified and prevention strategies to be developed," the authors suggested.
