Seeing the glass as half full: Taking a new look at cognition and aging 11-12

From a cognitive perspective, aging is typically associated with decline. As we age, it may get harder to remember names and dates, and it may take us longer to come up with the right answer to a question.
But the news isn’t all bad when it comes to cognitive aging, according to a set of three articles in the July 2014 issue of Perspectives in Psychological Science.
Plumbing the depths of the available scientific literature, the authors of the three articles show how several factors — including motivation and crystallized knowledge — can play important roles in supporting and maintaining cognitive function in the decades past middle age.

Motivation Matters
Lab data offer evidence of age-related declines in cognitive function, but many older adults appear to function quite well in their everyday lives. Psychological scientist Thomas Hess of North Carolina State University sets forth a motivational framework of “selective engagement” to explain this apparent contradiction.
If the cognitive cost of engaging in difficult tasks increases as we age, older adults may be less motivated to expend limited cognitive resources on difficult tasks or on tasks that are not personally relevant to them. This selectivity, Hess argues, may allow older adults to improve performance on the tasks they do choose to engage in, thereby helping to account for inconsistencies between lab-based and real-world data.
Prior Knowledge Brings Both Costs and Benefits
Episodic memory – memory for the events of our day-to-day lives – seems to decline with age, while memory for general knowledge does not. Researchers Sharda Umanath and Elizabeth Marsh of Duke University review evidence suggesting that older adults use prior knowledge to fill in gaps caused by failures of episodic memory, in ways that can both hurt and help overall cognitive performance. While reliance on prior knowledge can make it difficult to inhibit past information when learning new information, it can also make older adults more resistant to learning new erroneous information.
According to Umanath and Marsh, future research should focus on better understanding this compensatory mechanism and whether it can be harnessed in developing cognitive interventions and tools.
Older Adults Aren’t Necessarily Besieged By Fraud
Popular writers and academics alike often argue that older adults, due to certain cognitive differences, are especially susceptible to consumer fraud. Psychological scientists Michael Ross, Igor Grossmann, and Emily Schryer of the University of Waterloo in Canada review the available data to examine whether incidences of consumer fraud are actually higher among older adults. While there isn’t much research that directly answers this question, the research that does exist suggests that older adults may be less frequent victims than other age groups.
Ross, Grossmann, and Schryer find no evidence that older adults are actually more vulnerable to fraud, and they argue that anti-fraud policies should be aimed at protecting consumers of all ages.

The world has its first fully organic state - and it’s in India 11-12







  • The UN ‘Oscar for the Best Policy’ was awarded to the northeastern Indian state of Sikkim.
  • This makes Sikkim the 1st fully organic state in the world with its sustainable agricultural policies that are inclusive and comprehensive of all socioeconomic aspects.
  • Pawan Kumar Chamling, the state’s Chief Minister, propagated ‘building an organic world together’.
It’s not news that the north-eastern state of Sikkim is a leader in sustainable policies. But, the state’s efforts were finally recognised by the United Nations (UN) garnering the award for having the world’s best food policies or what’s called the ‘Oscar for the Best Policy’. 

The world has its first fully organic state - and it’s in India.
In actuality, Sikkim was already fully organic when 2015 rolled in having started its journey to being sustainable back in 2003. 

According to Maria Helena Semedo, Food and Agriculture Organisation’s (FAO) Deputy Director, Sikkim’s policies have benefited over 66,000 family farmers. Rather than focusing on food security in isolation, the state’s food policies take socio-economic aspects like tourism, consumption, markets and development into its fold to form a comprehensive and inclusive approach toward agriculture. 

Sikkim’s organic world 

Unlike most regions that turn to sustainability and being organic as a solution once their natural capital in jeopardy, Sikkim’s organic policy came into being because of its treacherous terrain that makes normal farming methods obsolete. 

Going organic was an opportunity utilise land that was currently lying unused. 

Now Sikkim is home to bio-villages that employ effective microorganisms (EM) technology for compost and bio-pesticides. The agricultural fields use vermiculture hatcheries and compost-cum-urine pits for manure production. 

Even the seeds they use are organic, rather than the hybrids that are used in other parts of the country. With the ‘Seed Village Scheme’, Sikkim ensures that it has locally adapted high-quality seeds. And, in order to ensure that those seeds yield the maximum output, the state conducts regular soil health assessments. 

The transformation didn’t happen overnight. And the most important aspect of its success is probably the invention programme that was implemented to raise awareness about organic farming practices among farmers. 

That being said, it’s easier said than done. When Sikkim started on its journey to becoming an organic state in 2003, chemical lobbyists and opposition parties didn’t make it easy. Chamling asserted that it was through strong political commitment and hard work that Sikkim is where it is now. 

In fact, Sikkim’s story is a model example of sustainability that is currently being emulated in other northeastern states of the country and Kerala, who recently faced extensively floods as a result of unsustainable development amplified by climate change. 

Sikkim beat out 51 nominations from 25 countries from all over the world at the event organised by the FAO and the World Future Council (WFC). The state’s Chief Minister, Pawan Kumar Chamling, even stated, “Let us build an organic world together,” when accepting the award.

Indian Women Are Voting More Than Ever. Will They Change Indian Society? 11-11







In India’s patriarchal society, many more women are voting. Will their newfound clout reshape the country’s politics? 

Are Indian women voting at higher rates than before?


Women in India are casting their ballots more frequently, and in greater numbers. Today, women’s turnout has actually been higher than that of men in two-thirds of India’s state elections. This is a remarkable turn of events in a deeply patriarchal, conservative society.

Why is this so surprising?


Men in India have always turned out to vote in larger numbers than women, as far back as the data goes. As recently as 2004, men held an 8.4 percentage-point turnout advantage over women in national elections. But by 2014, that gap had shrunk to just 1.8 percentage points.



Why is this happening?

That remains something of a puzzle. There is likely a combination of push and pull factors at work: more women want to vote, and institutions are encouraging them more to go to the polls.
Indian women are steadily becoming more literate, more educated, and wealthier. This could be making them more politically aware. They have also been taking part in collective organizing in unprecedented numbers, usually through small local groups in which women encourage one another to save money and pool their resources to pay for emergency needs. Some evidence suggests that when women take part in these economic networks, they are more likely to get involved in politics. These groups were not set up to achieve a political goal, but they may be having political consequences.
State institutions have been trying to make voting easier for women as well. For instance, India’s Election Commission has been trying to encourage more women to vote by improving the safety of polling booths to reduce voter intimidation and by setting up separate queues for women on election day.

Why does this shift matter particularly in India?

For decades, voting in India has been a male-dominated enterprise. And because many more men have always turned out to vote, it is perhaps unsurprising that mainstream parties have never seen women as a vital constituency worth wooing.
It seems plausible that some concerns that disproportionately impact women—such as public safety or healthcare—have often taken a backseat, because women have historically tended to be less politically engaged than men.

Does this shift mean that more women are voting in India than men overall?

No, it doesn’t. More women are voting than ever before, but their overall size as a voting bloc still lags behind men.
This is because even though a higher percentage of female voters go to the polls, there is a significant gender imbalance in India’s general population. According to the country’s 2011 census, the country has approximately 943 women for every 1,000 men. This places India near the bottom at 186 out of 194 countries, according to the World Bank.
The sex ratio among India’s registered voters is even worse. There are only 908 women for every 1,000 men on the country’s voter rolls.
This means that, despite progress, Indian women suffer a double-blow at the polls: above and beyond an entrenched preference for sons (which results in illegal sex-selective abortion and fewer educational opportunities for girls than boys), women are less likely than men to be registered to vote.

Is the fact that more women are voting already making a difference in terms of policy?

It appears to be. As Indian women become more politically mobilized, this seems to be changing how Indian candidates campaign and how they govern once they are in office.
For example, in the state of Bihar, Chief Minister Nitish Kumar brought in a draconian new anti-alcohol law in 2015 when he was reelected. Kumar said that this ban was motivated by a promise he had made on the campaign trail to women, who had told him that rampant alcoholism was devastating their families and communities.
As India gears up for the 2019 general elections, women’s status has become a focal point of campaign rhetoric. Prime Minister Narendra Modi of the Bharatiya Janata Party (BJP) has made what are billed as female-friendly policies a hallmark of his platform.
Modi regularly says that his administration’s efforts to improve sanitation, improve welfare subsidies (for things like the education of girls and the provision of clean cooking fuel) , and guarantee universal banking are transformative for India’s women. This is because the burdens of inadequate service provision disproportionately fall on women. Women are more likely to shoulder daily household tasks such as gathering water for everyday use, or caring for sick children. Opposition parties have adopted this framing as well, to counter Modi’s claims.

How many more women are running as candidates compared to before?

The number of female candidates has gone up, but there is a long way to go.
In 1962, the first general election for which there is data on gender, a paltry 3.7 percent of candidates were women. This figure stayed roughly the same until 1991. In the 1990s, the proportion of women running for office began to rise, thanks to greater pressure on political parties to choose female candidates.
In 2014, just over 8 percent of candidates in parliamentary races were women. This is, at once, a big improvement and yet a tiny proportion in absolute terms.
According to data collected by Francesca Jensenius on Indian state elections, things are no better at the state level. Between 2011 and 2015, just 7.3 percent of candidates for state office were women.

What kinds of political office are Indian women running for?

Research has found that Indian women are more likely to run in two types of constituencies. First, female candidates are more common in constituencies that have relatively more men than women. This is startling, because one might expect women to run where they are better represented in the population. But this does not appear to be the case.
Second, women are more likely to run in constituencies reserved for historically disadvantaged groups. India has one of the most advanced systems of affirmative action found anywhere in the world. Roughly one-quarter of legislative seats at the state and national levels are reserved for two protected groups: Scheduled Castes, who are at the bottom of the Hindu caste hierarchy, and Scheduled Tribes, who make up India’s native, indigenous population.



Has the #MeToo movement tangibly shaken up Indian politics, or has it been more of a trending topic on social media?

The #MeToo movement has taken a long time to catch fire in India. But in the past month, the #MeToo hashtag exploded on social media, as Indian women began talking about how they have suffered verbal and physical harassment in and out of the workplace.



These accusations have affected the worlds of film, media, business, and even politics. For example, former minister of state for external affairs M.J. Akbar was accused of wrongdoing by more than twenty-one women and was forced to resign over the allegations. Although Akbar still retains his parliamentary seat and has vowed to fight the charges, his resignation from his position as minister was a major victory for the movement. Many more skeletons may tumble out of politicians’ closets in the weeks and months to come.

Will having more female voters, candidates, and politicians really change deeply held Indian cultural attitudes toward women’s role in society?

There is some evidence that having more women in office does change gender perceptions.
For example, one study of affirmative action for women in Indian local politics has found that, while having female politicians does not necessarily mean voters are less likely to prefer male leaders, it does help reduce stereotypes about gender roles in public and private life.
Another study has found that having female politicians can be extremely beneficial for the aspirations and educational attainment of girls living under their jurisdiction. Other new research has found that female representatives are linked to higher growth, as well as less corruption and political opportunism.

Are Indian women more likely to vote for female candidates?

No. There is little evidence to suggest that women in India are more likely to vote for female candidates. Parties led by prominent women also do not fare better than other parties among female voters, though this may be changing.
One study has found that providing additional security at polling booths brings out more women to vote—but the vote share for female candidates actually goes down as a result. One possible explanation is that many Indian women, like men, often have ingrained biases against female leadership.

 As Indian women vote more frequently, are they also joining the workforce in greater numbers?

 No, they are not. This is a central paradox of India’s political and economic future. Despite enjoying unprecedented social and political empowerment, Indian women are dropping out of the labor force at a rapid clip.
There is a well-known U-shaped statistical relationship between a given country’s per capita income and female participation in the labor force. In very poor and in very rich countries, women tend to participate in the workforce at higher rates.



But in the middle of the income distribution, women’s participation dips, as households reach a certain threshold of per capita income that encourages (or forces) women to stay at home.
Relative to countries at similar income levels, India’s female labor participation rate is a distinct outlier.
What’s more, the rate of Indian women working outside the home has gone from bad to worse. According to the International Labor Organization, India ranks 121 out of 131 countries in female labor force participation. Just over a quarter of women in the country are in the labor force today, compared to more than a third in 2005.

Daylight Saving Time May Cost America $434 Million From Lost Sleep, Index Shows 11-04




Changing the clocks an hour ahead for daylight saving time doesn't just cost us sleep -- it might also be costing the American economy as much as $434 million, according to a new index.

"The hour of sleep we lose each spring as part of daylight saving time has a broader collateral impact that this study has quantified in dollars and cents," Dan Schecter, who is the creator of SleepBetter.org, said in a statement. "While we may appreciate the extra hour of daylight that comes with moving our clocks ahead, this study provides a prudent reminder that it's a good idea to try to make up for that missing hour of sleep elsewhere."

The new index, developed by Chmura Economics & Analytics, shows the financial toll of an hour's sleep lost, based on past research on heart attack incidence (published in the New England Journal of Medicine), workplace injury in mining and construction (published in the Journal of Applied Psychology) and cyberloafing (published in the Journal of Applied Psychology) all with regard to daylight saving time. There were 360 metro areas included in the index (not including Hawaii and Arizona, since they do not observe daylight saving).

Researchers noted that the actual financial toll may even be higher, because the index did not include impacts on car accidents or injuries in other fields (like transportation or manufacturing). A past study in the New England Journal of Medicine showed an association between loss of sleep from DST and an increased car accident risk.

Based on the criteria used to develop this index, Morgantown, West Virginia, experienced the worst losses from daylight saving -- losing $445,685. That breaks down to each of the town's 129,709 residents losing $3.40; the national average found in the study was $1.70 per person.

This year, daylight save time begins on Sunday, March 10 at 2 a.m. That means people who live in areas affected by DST should move their clocks forward by an hour. While the purpose of daylight saving is supposedly to save energy, research has been mixed on whether it actually has any benefit in that area. National Geographic has a great overview of energy, with regard to daylight saving time.
