Mark Zuckerberg's paternity leave plan 08-21

As he did after the birth of his first child in 2015, Facebook CEO Mark Zuckerberg is taking two months’ paternity leave from the company when his second daughter arrives. This time, Zuckerberg will break up the leave, spending one month at home with his children and wife Priscilla Chan right after the baby’s birth and taking the rest of the leave in December.

Zuckerberg is using only half of the four months of paid parental leave that Facebook allots male and female employees. It’s still far more time than the typical father takes off work for the birth of a child in the US, where only 15% of companies in a national survey last year offered paid paternity leave.
The lack of paid leave for men hurts parents who want to share the experience of caring for their babies, and contributes to the persistent lag in women’s wages and workforce participation. Fully paid paternity leave is key to breaking a vicious cycle in which employers pay women less and bypass them for promotions in anticipation that they’ll take time off to raise children, making the lower-earning female partner the natural choice to take unpaid or partially paid leave that’s ostensibly offered to both parents.

As Quartz’s Gwynn Guilford pointed out in a 2014 analysis of parental leave policies in Sweden and Japan, the more parental leave men take, the sooner women go back to work. A 2010 study in Sweden found that a woman’s future earnings rose 7% for every month her partner took under the country’s paid parental leave system, which incentivizes both parents to take time off. Sweden has one of the world’s highest rates of working women, and a nearly non-existent wage gap.

But it’s not enough for companies to offer paternity leave. Men have to actually take it, and this is where Zuckerberg’s decision to make his family plans public is significant. In a 2014 survey by the Working Mother Research Institute, men reported a significant gap between the availability of family-friendly, flexible working policies and the degree to which they were encouraged to take them. Those who did feel supported by their employers reported more satisfaction with the company, their careers, and their home lives.

“At Facebook, we offer four months of maternity and paternity leave because studies show that when working parents take time to be with their newborns, it’s good for the entire family,” Zuckerberg wrote in a Facebook post. “And I’m pretty sure the office will still be standing when I get back.”
Meanwhile, there’s no better way to encourage employee behavior than to lead by example.

Researchers Make Surprising Discovery About How Neurons Talk to Each Other 08-21

Researchers at the University of Pittsburgh have uncovered the mechanism by which neurons keep up with the demands of repeatedly sending signals to other neurons. The new findings, made in fruit flies and mice, challenge the existing dogma about how neurons that release the chemical signal dopamine communicate, and may have important implications for many dopamine-related diseases, including schizophrenia, Parkinson’s disease and addiction.

The research conducted at Pitt and Columbia University was published online today in the journal Neuron.

Neurons communicate with one another by releasing chemicals called neurotransmitters, such as dopamine and glutamate, into the small space between two neurons that is known as a synapse. Inside neurons, neurotransmitters awaiting release are housed in small sacs called synaptic vesicles.

“Our findings demonstrate, for the first time, that neurons can change how much dopamine they release as a function of their overall activity. When this mechanism doesn’t work properly, it could lead to profound effects on health,” explained the study’s senior author Zachary Freyberg, M.D., Ph.D., who recently joined Pitt as an assistant professor of psychiatry and cell biology. Freyberg initiated the research while at Columbia University.

When the researchers triggered the dopamine neurons to fire, the neurons’ vesicles began to release dopamine as expected. But then the team noticed something surprising: additional content was loaded into the vesicles before they had the opportunity to empty. Subsequent experiments showed that this activity-induced vesicle loading was due to an increase in acidity levels inside the vesicles.

“Our findings were completely unexpected,” said Freyberg. “They contradict the existing dogma that a finite amount of chemical signal is loaded into a vesicle at any given time, and that vesicle acidity is fixed.”

The team then demonstrated that the increase in acidity was driven by a transport channel in the cell’s surface, which allowed an influx of negatively charged glutamate ions to enter the neuron, thus increasing its acidity. Genetically removing the transporter in fruit flies and mice made the animals less responsive to amphetamine, a drug that exerts its effect by stimulating dopamine release from neurons.

“In this case, glutamate is not acting as a neurotransmitter. Instead it is functioning primarily as a source of negative charge, which is being used by these vesicles in a really clever way to manipulate vesicle acidity and therefore change their dopamine content,” Freyberg said. “This calls into question the whole textbook model of vesicles as having fixed amounts of single neurotransmitters. It appears that these vesicles contain both dopamine and glutamate, and dynamically modify their content to match the conditions of the cell as needed.”

In the future, the team plans to look more closely at how increases in vesicle acidification affect health. A number of brain diseases are characterized by abnormal dopamine neuron signaling and altered levels of the neurotransmitter.

“Since we have demonstrated that the balance between glutamate and dopamine is important for controlling the amount of dopamine that a neuron releases, it stands to reason that an imbalance between the two neurotransmitters could be contributing to symptoms in these diseases,” said Freyberg.

The Diversity of Play, does it improve cognitive development in children ???

How does play affect the cognitive development of children around the world? Doctoral candidate Lynneth Solis is looking to find out.

Play is an integral part of a child’s development according to traditional research mostly conducted in Western societies, but what role does play serve and what does it look like for children in indigenous communities? Ed.D. candidate Lynneth Solis, Ed.M.’10, is determined to better answer that question. 

Solis’ research focuses on children’s cognitive development, specifically how young children play with each other and with objects to understand and build theories about the world around them, and how this is shaped by their cultural context.

After completing her master's in the Mind, Brain, and Education Program in 2010, Solis spent the following year as a research assistant with Project Zero working alongside Principal Research Scientist in Education Tina Grotzer, looking at children’s understanding of complex causal patterns in science. It was through her work at PZ that Solis expanded her own research into children’s cognitive development and how they use objects to understand complex scientific phenomena such as friction, balance, and other physical concepts. This in turn led her to include looking at play in crosscultural settings.

In 2015, Solis — the recipient of a Frederick Sheldon Traveling Fellowship through the Committee on General Scholarships at Harvard — spent a year working with and observing children in the Sierra Nevada de Santa Marta in Colombia. (The Kogi settlement in which she worked is pictured below.) What she found, contrary to prior research, was that indigenous children were engaged in complex forms of play that hadn’t been documented before.

“In the past, researchers reported that indigenous children didn’t play in complex ways, but I found them pretending and involved in object play and construction similar to the way children in the West play,” Solis says. “But I also found ways children in these communities would spend time together socializing, enjoying each other’s company without outwardly appearing very playful at first glance, but involved in unstructured and positive experiences that we could call play.”

After interviewing parents, Solis discovered even more variation from the narrative older research told. While some parents felt play was not part of their culture, others believed play helped prepare children for the future inside and outside their community.

“They saw play as a way for children to feel more confident speaking, expressing themselves, and interacting with adults and other children within and outside their culture,” says Solis “They also expressed that they believed play could help their children to explore their environment, learn, and develop creativity.”

Grotzer says that Solis’ important ethnographic work is helping the field of children’s cognitive development better understand the diversity of play and its role in cultures outside the West, and understanding what parents and community members believe about play is crucial for designing educational interventions.

Kogi settlement in Colombia“Lynneth is able to set aside her own cultural assumptions to really ‘see’ what is going on and to interpret it through the eyes of the cultures that she is studying,” Grotzer says. “The stories of her work convey the extraordinary ability that Lynneth has to ‘become one’ with the children such that they have included her in their hidden worlds and have given us a rare window into their childhoods.”

It was critical to her research in Colombia, Solis says, to be trusted by children so that they would invite her into their play spaces. “When they said let's go to the river to swim, I went to the river, and when they went on crab hunts at the beach at night, I ran along the ocean with them,” she says. “This meant refraining from acting like an authority figure, so I became a curious companion who happened to always be writing notes and documenting their activities.”

Solis has also been working closely with the Lego Foundation, in partnership with the Center on the Developing Child at Harvard University, to better understand the science of play to support learning, which she says is an important next step for the field.

“There’s a call for systematic research on play,” Solis says. “Up to this point there’s been a lot of correlational research, but now methodological advances get us closer to understanding the developmental mechanisms involved in play from a biological and neurological perspective. I feel like I’m on the beginning journey of that and it feels exciting.”

Solis’ work has not gone unrecognized. During her time at HGSE as a master's candidate she was named an Intellectual Contribution Award winner, and last year she was a Julius B. Richmond fellow at the Center on the Developing Child and AERA Minority Dissertation Fellow. While she is set to graduate next year, Solis plans on continuing her research to expand understanding of child development.

“I’m very interested in indigenous communities here in the States and abroad and expanding the stories we tell in child development,” Solis says. “It’s important to tell stories of diverse populations to really understand child development, and the more varied stories we tell, the more we understand.”

Man orders 50-inch TV on Amazon, gets 13-inch monitor 08-13

A resident of Mumbra, a town on Mumbai outskirts, is fighting for a refund from Amazon since past two months but to no avail.

Mumbra resident Mohammad Sarwar had ordered a 50-inch television set on Amazon's website in May and paid Rs 33,000 via credit card.

Sarwar received the package on time but was advised not to open it until a technician comes to install it.

"They said I may inadvertently damage the TV while opening the box. I left the box intact, which I now realise was a big mistake," he told Mirror.

When the technician arrived a day later, there was no TV inside the box but a 13-inch Acer monitor, which appeared to have been used before.

Sarwar has been fighting for a refund since then.

"I made several calls before a customer service agent said the refund would be issued only after I sent the package back. I was told I would have to bear the courier service charges. The suggestion left me furious, but I wanted my money back so I agreed," he said.

The story does not end here. A courier company refused to send the monitor as it didn't have an office near his house.

Meanwhile, Sarwar claims Amazon did not pay heed to his calls.

"The e-tailer's customer support took its own sweet time every time I called. It kept transferring my calls from one agent to another. I even sent emails and shared my grievance on social media. Nothing happened," he said.

An Amazon spokesperson told Mirror it was trying to resolve Sarwar's complaint. "We are in touch with the customer and are committed to resolving this at the earliest," the official said.

"I understand as an e-commerce site, they (Amazon) have their limits, but they can't keep me hanging after delivering a wrong product. I will take the matter to a court, if that's what will make them take customers seriously," said Sarwar.

RBI's dividend to govt halves to Rs 30,659 crore 08-11

The Reserve Bank of India (RBI) will transfer Rs 30,659 crore of its surplus to the government for the financial year 2016-17, less than half of the Rs 65,876 crore it transferred a year earlier.

The RBI did not provide any reason for the decline in dividend but economists said this indicated the cost incurred by the central bank in printing new notes as well as in sterilising liquidity after old Rs 500 and Rs 1,000 currency notes were scrapped in November and subsequently returned to the banking system.

The dividend paid is the lowest since 2011-12, when the RBI had transferred Rs 16,010 crore of its surplus to the government. In 2012-13, the central bank paid Rs 33,010 crore. The RBI’s financial year runs from July to June. The central bank is expected to publish its annual reports next week after its board met on Thursday to clear the accounts. 

In 2012-13, the YH Malegam Committee recommended the central bank transfer its entire surplus to the government. The RBI has been transferring its entire surplus to the government since then. It paid Rs 52,679 crore in 2013-14 and Rs 65,896 crore in 2014-15.

In the Union Budget for 2017-18, the government had accounted for a dividend of Rs 74,901 crore from the RBI and other nationalised banks. An official later said the RBI’s share would be Rs 58,000 crore. 

RBI Governor Urjit Patel told a parliamentary panel in July that the central bank had not finished counting the old returned notes. 

He has also said notes not returned remain the RBI’s liability and cannot be passed on to the government as dividend. 

The Union Budget had not accounted for any special dividend from the RBI against demonetisation, which some economists had estimated would be in the lakhs of crores of rupees.

The low actual dividends, meanwhile, will exert pressure on the government to meet its fiscal deficit. Care Ratings Chief Economist Madan Sabnavis said the fiscal deficit could increase from 3.2 per cent of the GDP to 3.4 per cent this year. At its peak, the excess liquidity parked by banks neared Rs 5 lakh crore, on which the central bank had to pay them 6 per cent interest. The average daily liquidity absorption continued to remain above Rs 2 lakh crore after demonetisation was announced.

According to Devendra Pant, chief economist of India Ratings & Research, the appreciation of the rupee against the dollar depressed returns, in rupee terms, on the RBI’s foreign holdings. The rupee has appreciated by more than 6 per cent against the dollar since January.
