The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study

Bengaluru, June 11: Amulya Leona, a college student, who was charged with sedition for raising "Pakistan zindabad" slogans in Bengaluru, has finally been granted bail. 

The court had denied her bail yesterday, saying she might abscond. But her lawyers had been pursuing another way of getting her out of jail where she has spent nearly four months.

Ms Leona's advocate, Prasanna R, said that the delay of the state in submitting a chargesheet in the case beyond the stipulated time meant she was eligible for "default bail".

"The default bail application was moved before the magistrate under whose jurisdiction the alleged crime was committed. The chargesheet has not been submitted by the state within 90 days. So default bail has been granted. We had moved the default bail plea on May 26 and again on May 29 when the court told us the earlier mail IDs had been disabled. A physical application was filed on June 2. The state filed the chargesheet on June 3," the lawyer said.

While the state tried to argue that they were entitled to an extension in the time allotted, the court hearing this aspect of the case gave an order favourable to Ms Leona. The process is on to release her.

The arrest of Ms Leona during a rally against the Citizenship (Amendment) Act or CAA in Bengaluru had led to a debate on the use of sedition charges.

The woman on a Facebook post had also said "zindabad" to many countries including India and Pakistan. She did also try to chant "Hindustan zindabad", but was soon silenced and whisked away. She was accused of sedition, causing enmity between communities and causing deliberate mischief.

Veteran journalist P. Sainath has said that the nation is in a crisis. And this crisis is not limited to just the rural area. It has become a national crisis at various areas such as agriculture, education, economy, job creation etc.

He was delivering the endowment lecture on the topic ‘Indian democracy at the post-liberalization and post-truth era’ at Media Manthan 2020 organized by the PG department of journalism and mass communication at St Aloysius College (Autonomous). 

Mr Sainath said that the many policies adopted in the 90s led to India becoming unusually unequal. Referring to the speech Ambedkar had made at the Constituent Assembly while handing over the draft of the Constitution, Mr Sainath said, “Ambedkar had warned about the weakness of Indian democracy that liberty without equality allows the supremacy of a few over the multitude. Liberty, equality and fraternity must be kept together as we cannot have one without the other.” 

Mr Sainath stated that the agrarian crisis was no longer about the loss of productivity, employment or about farmer suicide; it was a societal, civilizational crisis. Commenting on the lopsided policies such as cow-slaughter ban, he explained how cow slaughter ban had adversely affected many industries due to their interdependency. While Muslims who slaughtered cows were rendered helpless, the cattle traders who were mostly OBCs lost their earnings as the cattle prices crashed. An important industry like Kolhapur sandals industry in Maharashtra went bankrupt as a result of the cow slaughter ban in Maharashtra. He said the policymakers had no idea how the rural industries were interconnected. Demonetisation too devastated the rural economy as 98 percent of rural transactions happen through cash. 

Mr Sainath also spoke about the crisis of inequality which affects the Dalits and the Adivasis far more than anyone else as 90 percent of the rural households take home less than Rs 10,000/- per month. “Women are yet another group whose labour is never counted in the gross domestic product. Women and girls globally do unpaid work which amounts to about 12.5 billion working hours per year. Monetarily speaking, this is worth 10.8 trillion dollars,” Mr Sainath added. 

Speaking about the crisis of jobs Mr Sainath said that major companies were laying off employees just to create more profits for the investors and the adoption of artificial intelligence in the industry would further destroy millions of jobs.

‘Veerappan and Vijay Mallya’s business models are interesting!’

Addressing the gathering during his endowment lecture on Friday, Mr Sainath made an interesting comment on the so called ‘revenue model’. “Whenever I visit IIMs and IITs for lectures on my PARI project, the students there ask me what my revenue model for my project is. I tell them that I do not have a revenue model. In fact, journalism does not begin with a revenue model. Gandhiji, Ambedkar, Bhagat Singh were all great journalists. But they did not have a revenue model,” Mr Sainath said.

On a lighter note, he said that the best revenue model that he liked was that of forest brigand Veerappan and liquor baron Vijay Mallya. “Veerappan ruled the forest for forty years and from the top ministers to the villagers he could dictate terms and liver royally. Similarly, Mallya’s revenue model was to steal the banks and run away abroad and live like a king,” Mr Sainath added.

Journalism is not and can never be a business. It is a calling, he opined. While newspaper can be a business, television can be a business, journalism per se cannot be reduced to a business. “Unfortunately today, journalists are recruited on a contract basis and they have no bargaining power; and there are no unions to fight for their cause. Hence, they are at the mercy of the corporate media houses for their survival and are made to write stories that cannot be called journalism,” Mr Sainath said.

Answering a question as to the pressures he faced as a journalist, he said that external pressures from the government or others could be very well handled. It is the internal pressures from once own media house that journalists find it difficult to manage.
