What is 'dumb agent theory' in economics?

This refers to the hypothesis that decisions made by groups of individuals turn out to be better than the decisions taken by isolated individuals. It is used to emphasise the wisdom of crowd knowledge. The dumb agent theory has been used in support of the efficient market hypothesis which states that the the prices of securities properly reflect their true underlying value. It has also been applied in the field of prediction markets where the wisdom of the crowd, rather than an individual, is employed to forecast the future to the best possible accuracy level. The idea was first conceptualised by American journalist James Surowiecki.

Searching for an elusive peace


India must remain engaged with the multiple processes underway on Afghan reconciliation

Russia hosted a regional conference on Afghanistan last week to nudge the reconciliation process between the Taliban and the Afghan authorities. The Taliban were represented by the political council chief, Sher Mohammad Stanikzai. Representatives from Afghanistan, China, Pakistan, Iran, Kyrgyzstan, Tajikistan, Uzbekistan, Kazakhstan, Turkmenistan, the U.S. and India swere also present at the meeting, making it the first time that all stakeholders were present in the same room.
Back in the game
Considerable political manoeuvring preceded the meeting. It was earlier planned for September, but failed to materialise. The Taliban were opposed to attending since the Afghan government insisted on co-chairing the meeting. The diplomatic solution was to have Afghanistan represented by the High Peace Council (HPC), set up and supported by the government with the specific aim of furthering peace talks, though formally not part of government. India sent two seasoned former diplomats, with the Ministry of External Affairs describing its participation as “non-official”. The U.S. was represented by its Moscow embassy officials. Aware of the differences, the Russians refrained from attempting a final statement or even a group photograph. Nevertheless, with this meeting, Russia has sent a clear signal that it is back in the game in Afghanistan.
The idea of reconciliation with the Taliban has been around for over a decade. As the Taliban insurgency grew 2005 onwards, the British, deployed in Helmand, soon found merit in doing side deals with local Taliban commanders by turning a blind eye to opium production in the area. With the help of the Germans and the Norwegians, they began to persuade the U.S. to work for a political outcome.
After being elected in 2008, President Barack Obama ordered a full-scale review of the U.S.’s Afghanistan policy. After extracting an assurance from the generals that the insurgency would be defeated in 18 months, Mr. Obama announced a shift to counter-insurgency mode with a surge of over 40,000 troops, but added that phased drawdown of troops would begin in end-2011. Operation Enduring Freedom formally ended in December 2014, handing over primary responsibility for combat operations to the Afghan security forces even as the insurgency gained ground.
The U.S. soon realised that it had run out of options. Insurgency could not be contained as long as sanctuaries existed in Pakistan and the carrot and stick policy with Pakistan had cost the U.S. $33 billion but failed to change Pakistan’s policy. A total cut-off was not possible as long as U.S. troops in Afghanistan depended on supply lines through Pakistan. In 12 years, the U.S. had lost 2,300 soldiers and spent $105 billion in rebuilding Afghanistan, more than $103 billion (in inflation-adjusted terms) spent under the Marshall Plan on rebuilding West Europe after World War II. War weariness demanded an exit and a political solution was unavoidable.
Taliban’s growing visibility
After prolonged negotiations, a Taliban office opened in Doha in June 2013 to promote talks and a peace process. However, when the office started flying the Taliban flag, calling itself the political bureau of the Islamic Emirate of Afghanistan, it angered both the U.S. and Afghan governments. The office was closed down though the Qatar authorities continue to host Taliban leaders.
Coming to power in 2014 after a bitterly contested election, Afghan President Ashraf Ghani moved to improve relations with Pakistan, even calling on then Army Chief, Gen. Raheel Sharif, at the GHQ, to push for reconciliation. Preliminary talks were held in Murree but derailed in July 2015 when Mr. Ghani asked for a supportive audio/video (instead of a written statement) by Taliban leader Mullah Omar and learnt that he had died over two years earlier.
An internal power struggle within the Taliban erupted with Mullah Akhtar Mansour emerging as the leader. Insurgency grew with the Taliban briefly taking over Kunduz and Ghormach districts and threatening Ghazni. Mr. Ghani felt betrayed and lashed out, accusing Pakistan of “waging war”.
A new initiative (Quadrilateral Coordination Group) involving the U.S., China, Pakistan and Afghanistan was launched in January 2016. After a couple of meetings, there was a roadmap; Pakistan was to use its influence to get the Taliban to the negotiating table. Hopes were dashed when the Taliban demanded exit of foreign troops, release of detainees from Guantanamo, and removal of its leaders from international blacklists. Frustrated with Pakistan’s inability to get Mullah Mansour to fall in line, the U.S. eliminated him in a drone strike in May 2016 in Balochistan. Maulvi Haibatullah was appointed as his successor.
Meanwhile, there were signs that the Islamic Movement of Uzbekistan and the Tehrik-i-Taliban Pakistan were converging under the banner of the Islamic State (IS) in Afghanistan’s northern and eastern provinces. In December 2015, Russia publicly acknowledged that it had “communication channels with the Taliban for exchange of information” and “a shared interest with the Taliban to counter the threat posed by the IS”. Clearly, it was getting back into the game. Preliminary consultations were held in 2017, at which Afghan officials (and senior Indian diplomats) were present but the Taliban declined to share the table with the Afghan government.
Remaining engaged
Mr. Ghani launched the Kabul Process for Peace and Security Cooperation, and in February, made an unconditional dialogue offer to the Taliban. The Taliban rejected his overture, declaring that they were ready to engage in direct talks only with the Americans. Mr. Ghani persisted, resulting in a three-day ceasefire during Eid. The U.S. softened its stand on an “Afghan-led and Afghan owned peace process”, and in July, senior State Department official Alice Wells was in Doha for a meeting with the Taliban. In September, the State Department announced the appointment of Zalmay Khalilzad (former U.S. Ambassador to Afghanistan) as Special Representative for Afghanistan Reconciliation. Mr. Khalilzad, a pushy go-getter, has since been making the rounds in Qatar, Saudi Arabia, the U.A.E., Pakistan and Afghanistan.
Meanwhile, the situation continues to worsen. Today, the Afghan government controls barely half the country, with one-sixth under Taliban control and the rest contested. Most significant is the ongoing depletion in the Afghan security forces because of casualties, desertions and a growing reluctance to join. U.S. President Donald Trump’s South Asia policy announced last August aimed at breaking the military stalemate by expanding the U.S. and NATO presence, putting Pakistan on notice and strengthening Afghan capabilities has clearly failed, and this is why multiple processes are underway. Everyone agrees that the war has to end; the question for the U.S. is how to manage the optics of the exit while not conceding victory to the Taliban.
Since July 2011, when the former President and Chair of the HPC, Burhanuddin Rabbani, visited Delhi, India has supported an ‘Afghan-led and Afghan-owned’ peace process. Last month, during Russian President Vladimir Putin’s India visit, both countries expressed their commitment to the Moscow Format. India doesn’t have the leverage to play spoiler but its presence is recognition that its economic cooperation programmes make it the most widely accepted development partner. Pragmatism dictates that India remain engaged with the multiple processes underway. Peace remains elusive but India’s engagement demonstrates commitment to the idea of a stable, independent and peaceful Afghanistan.

Can technology change the way our children learn?

The combination of innate curiosity and a hands on approach to learning will help foster a culture of continuous learning

A decade ago, when kids wanted to research a school project, they stopped by the library. They consulted a well-thumbed encyclopedia at home, or they asked you, the parent. Children today – comfortable with voice-based technology – turn to a digital assistant like Google Home or Amazon’s Alexa for help. They search online on their smartphones or iPads. Technology is fundamentally altering how children imbibe knowledge. It is also transforming the delivery of education for newer generations, whose lives are enmeshed with the devices and technology that power their world. I see this radically changing how our children will learn in the future and how we as parents and teachers, need to respond through this change. With the right intervention, techenabled transformation in education can close critical gaps in the traditional classroom of today, even as it opens up new opportunities for our children.
THE END OF ONE-SIZE FITS-ALL
Personalization is already touching so many aspects of our kids’ lives. They are used to tailormade choices, right from the delivery app that pulls up their favorite pizza, to the shows recommended just for them on Netflix. In education, this has deeper implications and benefits. Technology is making a far more adaptive and personalized learning experience possible. Every child does not learn at the same pace. Or have the same learning style. Teachers in a traditional classroom with over 40-50 children have very little scope to individually assess students. Artificial intelligence powered adaptive learning software systems are now solving this problem – courseware can be customized to meet the child’s individual learning needs, at their level. We are moving to a future where the curriculum will be personalized for every child in the classroom. Children will be able to learn at their own pace, on individual learning paths, for optimum results.
CLASSROOM OF THE FUTURE
Technology is shaping the classroom of the future. Students will move seamlessly from a traditional to a global virtual classroom in the same school day. Video communication tools will allow them to interact with classmates from around the world as they work in real time on a school project. Debate clubs would stream live from two or more continents. Virtual classrooms would open up access to highquality learning or specialized curriculum, besides giving children exposure to rich multicultural experiences and communities far removed from their own. Schools across the world are already bringing virtual and augmented reality into the classroom – technologies that can turn learning into an immersive, often magical experience. With apps like Google Expeditions, for instance, students can take field trips from their classroom with the teacher as a guide, see and walk around a place or object.
A ‘SMALL’ REVOLUTION
Our kids are growing up reading flash fiction. They microblog and think in 140 characters. The way they express themselves and communicate is also extending to the way they want to learn. Research shows us that learners online prefer to study in bitesized increments. They want concise, crisper modules that are engaging. They want learning content to meet the same high engagement standards they expect elsewhere in their lives.
Technology is also bringing a more fundamental shift in the path to education. Future learners will adopt a flexible approach to build relevant skills, as technology – moving at an unrelenting pace – makes existing skills redundant.
Our children will go into a workforce where they will need to continuously build competencies to keep up with technology and stay agile. Stackable, rather than single, monolithic credentials that take years to acquire, will disrupt how students acquire education. Learners will be able to accumulate a series of credentials, studying with flexibility, as they move towards a single degree..
LEARNING TO BE LIFELONG LEARNERS
On Coursera, one of the most popular online courses of all time, with 2 million enrollments, is Learning How to Learn, developed by Dr. Barbara Oakley from Oakland University. It teaches students how to use tools drawn from neuroscience to learn more successfully – critical for the future. Helping children learn ‘how to learn’ and master new or tough subjects will be increasingly important for their success. Our children will need to be lifelong learners in an unpredictable workplace, where a college degree alone no longer suffices. Learning will become a way of life, not a stage in life.
Models like online learning will offer them the flexibility they need to be continuous learners. Learners are already seeking greater convenience. They want to watch a 20-minute video on the way to work, for example. A mobile experience is helping them learn on the go, on a device of their choice.
Perhaps the more important shift will be “what” our children learn. “We cannot teach our kids to compete with machines. They are smarter. We have to teach something unique,” Jack Ma, founder of Alibaba Group, told an audience at this year’s World Economic Forum Annual Meeting. He argues the “knowledge based approach of 200 years ago” would “fail our kids” because it does not prepare them to compete with machines. Children, he believes, should be taught “soft skills like independent thinking, values and teamwork.” According to the McKinsey Global Institute, robots could replace 800 million jobs by 2030. Skills like creativity, lateral thinking and adaptability will be indispensable for our children in this age of automation.
Helping them develop these skills will be the most important contribution we as parents or teachers can make, to prepare our kids for a new future. As the contemporary world continues to change, the term ‘digital disruption’ has become a watchword in the industry. Efforts today are consistently geared towards maximizing one’s potential through regular skilling to adapt to changing industry requirements. At its core, however, the abilities that form the foundation upon which the skilling process takes place have remained relatively unchanged. These abilities, hence, must be inculcated early in life to ensure individuals are capable of achieving their optimal potential in society.

Movement to Stillness

There are only two things to what we know as life: stillness and movement. The physical creation that we see around is the movement, and that which creates is stillness. Every movement or creation we see around is born out of stillness, survives and thrives in stillness, and sinks back into stillness. Movement is ‘samsara’ or ‘maya’ as we know it and stillness is divine. If your ‘prana’, life-force, that which creates, goes for and around creation, then you belong to ‘samsara’, and if the same energy goes in pursuit of stillness, then you are spiritual. These are the only two ways to exist and there is no third choice, really. Movement is a short happening between time and space as we see the way creation is happening. Stillness is eternal, beyond time and space. If we are lost in creation, then it will lead to repetition — what we know as cycles of life. But realising one’s stillness is ultimate freedom — from life and death. Meditation is stillness. This is to reverse the flow of our ‘prana’, currently going out in various directions and lost in movement, to go within or toward stillness. This is the meeting of Shakti with Shiva, or creation and creator. Your energies are now finding its way back to the Source. To get lost in creation is untruth, but to consciously merge with the Source is to realise the Truth. An enlightened being is one who is always established in the stillness and movement for him is as needed — always conscious and never compulsive. Spirituality is a journey from movement to stillness.

What is 'contact hypothesis' in sociology?

Also known as the inter-group contact theory, this refers to the hypothesis that people-to-people contact may be a good way to resolve conflict between groups. It was proposed by American psychologist Gordon W. Allport. The contact hypothesis is based on the idea that peaceful and friendly interpersonal contact can help in reducing prejudices between groups and foster better cooperation and friendly relationships. Some believe that such interpersonal contact between people can help reduce conflict by increasing interdependence between the groups. In other words, the cost of conflict increases with greater interdependence.

Gender, income and geography bias remain in health delivery

The Pneumonia and Diarrhoea Progress Report 2018, which tracks efforts to being down deaths from the two preventable diseases that killed 1.36 million under-5 children – one in four under-5 child deaths globally – said 70% of the global deaths continue to occur in 15 countries, including India.

More children in India are getting immunised against vaccine-preventable illnesses than ever before, but progress remains mixed and a lot more needs to be done to prevent illnesses among poor and marginalised children in both urban and rural areas, according to a new report.
The Pneumonia and Diarrhoea Progress Report 2018, which tracks efforts to being down deaths from the two preventable diseases that killed 1.36 million under-5 children – one in four under-5 child deaths globally – said 70% of the global deaths continue to occur in 15 countries, including India.
With 26 million births every year, it was not surprising that India had the most pneumonia and diarrhoea deaths with 260,990 children dying in 2016, followed by Nigeria and Pakistan.
What was worrying was that India tied with Pakistan for the seventh place among 15 countries in the Integrated Global Action Plan for the Prevention and Control of Pneumonia and Diarrhoea (GAPPD) score, which ranked countries on delivering key life-saving interventions such as breastfeeding, vaccination, access to care, use of antibiotics, ORS, and zinc supplementation. Tanzania followed by Bangladesh topped the ranking.
Despite India showing improvement in child health, indicated by falling under-5 mortality rate (U5-MR), from 43 in 2015 to 39 per 1,000 births in 2016, a deeper dive into data reveals that access to vaccination and interventions varies substantially by geography, gender, mother’s education and income.
The gender gap in routine immunisation coverage remains across India, which is reflected in the U5-MR data. Despite an impressive 9% annual drop in under-5 deaths, U5-MR is 37 for boys and 41 for girls, which indicates more girls continue to die of preventable causes before their fifth birthday. Even in low-income areas and urban slums in Delhi, 78 girls were fully immunised for every 100 boys.
India’s scores for exclusive breastfeeding declined, as did coverage of oral rehydration solution used to treat diarrhoeal disease, which is given only to barely 20% sick children, found the report.
Along with promoting breastfeeding, increasing Haemophilus influenzae type b (Hib) vaccination, scaling up the rotavirus vaccine that was first introduced in mid-2016 against diarrhoea, and expanding the pneumococcal conjugate vaccine (PCV) beyond six states can lead to further fall in child deaths. The report recommends the use of high-quality data to ensure children are not missed and the country meets the UN’s Sustainable Development Goal target of reducing U5-MR to less than 25 per 1,000 live births by 2030.
Recognising that vaccines are the most effective way to stop preventable deaths from infections and disease, India expanded its vaccine arsenal under universal immunisation programme and vaccinated at least 106.144 lakh children under Intensified Mission Indradhanush in 2017-18.
Apart from the seven vaccines that gave the programme its name -- tuberculosis, poliomyelitis, hepatitis B, diphtheria, pertussis, tetanus and measles – new vaccines against measles rubella, rotavirus, Hib, PCV and polio have been added, along with Japanese Encephalitis vaccine for children under 15 in 112 endemic districts.
The target is to reach the unvaccinated and partially vaccinated to reach at least 90% children by December 2018.
The benefits of vaccination go beyond the immunised child. Vaccinating a critical mass of people in a community creates a “herd immunity” that protects even those who haven’t been vaccinated. In cases where a vaccine offers partial protection, such as flu vaccines, people who have been vaccinated have milder symptoms, lower chances of hospitalisation and complications, less use of potent antibiotics and anti-virals, and lower risk of death.
Apart from the direct savings on cost of treatment, the indirect gains include staying healthy, not missing school, increased productivity, better educational attainment and improved job potential, all of which lead to an improved quality of life.
