Many children today transition from playfulness and innocence to mental stress and other worries during adolescence. It is crucial to understand children’s issues and actively seek solutions rather than fretting over them. These challenges during a critical stage of development can significantly impact children’s memory and intelligence.

A world full of happiness and no worries… Such is the view of parents and guardians about the world of children. They don’t have to worry about work to be done or responsibilities, so what’s the stress on them? But the data coming out about children’s mental health suggests that these are all just our misconceptions.

The number of children seeking counseling and mental health treatment is increasing day by day. To those who wonder what tension they have for this alone, they say, many. At a very young age, children experience minor stress or mental tension!

What is stress?

What is stress if it affects even children? Stress is the body’s coping mechanism to deal with and adapt to challenging situations. A balance of demands from multiple sources or the ability to meet them leads to stress. Such demands may come from family, work, school, or friends, and sometimes one’s own demands can also lead to stress. Stress occurs when the demand and the ability to meet it do not match.

Dr Rashmi Prakash, a member of the Australian Psychological Society, says that a small amount of stress is beneficial to children. But stress can have long-term effects on children if it goes too far

Stress occurs in children for many reasons. The worry of missing parents at a very young age, academic issues later in life, social pressures, mental and physical abuse, problems between parents and isolation all contribute to stress in children. Dr Rashmi Prakash, a member of the Australian Psychological Society, says that a small amount of stress is beneficial to children. But stress can have long-term effects on children if it goes too far. Recently Indian researchers have found that childhood stress can affect memory skill of students.

Research conducted by a team consisting of Radha Raghuraman, Anoop Manakadan, Gal Richer Levin, and Sreedharan Sajikumar, in 2022, found that childhood stress can have a detrimental effect on memory.

How to spot stress in children

Stress and related problems in children can be difficult to identify, but sudden anger, mood swings, misbehaviour, changes in sleep patterns, and bedwetting can all be considered signs of stress. Some may also experience physical effects due to stress. For example, stomach ache and headache. Others have symptoms such as lack of concentration and inability to complete studies. Apart from this, being away from everyone and spending a lot of time alone is a sign of stress. Signs of stress include thumb-slapping, hair-twisting, nose-picking in young children, and lying, bullying, and backbiting in adults. Stressed out children can get into big fights even over small things. Falling behind in studies is also a symptom of stress.

The connection between stress and memory

Experts say that children are more stressed than adults. This is due to constantly having to face new and confusing situations. Children are greatly influenced by the expectations placed on them by the adults around them, especially parents and teachers. Children often judge themselves by those expectations. When those expectations are not met or when their skills, abilities, and pride are called into question, they are unable to cope.

Separation from parents especially mother, physical or mental abuse, fear etc. can lead children of any age to stress

Recent studies have shown that stress levels in children have been on the rise over the past few decades. Radha Raghuraman says that exposure to stress during childhood can affect the ability to connect different types of memories as adults. The research team conducted studies on this in mice. As the juvenile phase in mice is equivalent to the adolescent phase in humans, adolescent stress is the main concern here. Radha explains that since the structures of the memory-related brain regions of mice and humans are almost identical, their findings may hold true for humans as well.

Separation from parents especially mother, physical or mental abuse, fear etc. can lead children of any age to stress. Depending on the age at which stress occurs, how long it has lasted, the intensity, and the type of stress, the changes it causes in the body and behaviour will vary.

Adolescent stress stimulates certain epigenetic factors. Like a gene, a piece of DNA that carries information necessary for specific functions in a cell, an epi-gene is a factor that causes a gene to decide whether or not to express the information in the gene, and if so, how much to express.

Parental proximity also plays a major role in reducing stress in adolescents. Even after work, you should be interested in sitting with the children and asking about their affairs.

Through their study, Radha and his team found that stress during adolescence results in increased activation of the epi-gene G9a/GLP. It affects the formation of certain proteins that stabilise newly formed memories. As a result, memories that have already been formed are perfected and as they grow, there is no room for other memories that come in connection with them. Associative memory is the ability to connect existing memories with recent or recent events and find similarities and dissimilarities between them. Adolescent stress mainly affects associative memory. Radha says that G9a/GLP was found to be significantly higher in stressed mice. The researchers also found that associative memory was restored when G9a/GLP was blocked with the drug.

How to save children from stress

Adequate rest, nutritious food, closeness, attention and care of parents can give children a lot of relief from stress. Parents should try to be with their children when they want. If you notice that there are any problems, talk to them openly instead of thinking that they will tell you here.

Parental proximity also plays a major role in reducing stress in adolescents. Even after work, you should be interested in sitting with the children and asking about their affairs.

Studies remind us that stress during adolescence should be viewed more cautiously than stress at any other time. Adolescence is also a period of growth in children. Facing stress at a time when the development of many important organs including the brain is not complete can lead to many types of consequences while growing up.

India: Big Science in the 20th century and beyond

In this blog post, Ed Publica’s Science Editor, Karthik Vinod, skims over some of the state-funded science projects in India that existed before and after independence.

Science after World War II

Scientific research changed forever in the aftermath of the World War II. Nuclear weapons entered the fray, and scientists worked – not alone anymore – but now in groups rivalling organizations. Governments walked in for the first time, institutionalizing science as a state-project. In the US, Vannevar Bush’s Science: the Endless Frontier advocated for a dichotomy within science, between applied and basic research. India soon advocated for something Though flawed, it’s a blueprint used across the world, including in India. But it needs to change.

Following independence, Jawaharlal Nehru, India’s first prime minister, resorted to building centralized institutions across the country, with the Indian Institute of Technologies (IITs) being famous amongst those pursuing a technical stream. Along with the Indian Institute of Science (IISc.), they’ve attracted the country’s most meritorious and bright students. Nehru viewed and appreciated scientific thinking as a “way of life” and an aspect that’ll break the shackles of superstitious belief in many Indians. He popularized the phrase “scientific temper”, which was later amended into the Indian constitution by his daughter and late prime minister, Indira Gandhi. However, this was during the Emergency Period, when democracy was curtailed, dissidents were imprisoned, and mass sterilization campaigns castrated many men against their will.

Keeping political hypocrisy aside, the administrations since then hasn’t picked up much steam either on being serious about its fundamental scientific research. This is not to say there hasn’t been marvels in technological innovation. Vikram Sarabhai, the technocrat scientist and aristocrat, who helped seed incentives for the country to invest in a space program, envisioned science and technology to enable Indians use of state-of-the-art technology, without going through the rudimentary “stages of growth” that was thought to plague many developing nations. The Indian Space Research Organization (ISRO) builds satellites and rockets, and has been the harbinger rather in public eye for the country’s assertive rise as a space power. Fundamental science research has taken a backseat, with funding woes and political apathy felt even today.

Funding for ISRO virtually trumps anything else that churns in public scientific institutions. Though this is a common attributed share among space faring nations, India’s amongst the lower tier of nations that spends on research and development (R&D) – constituting just 0.64% of the Indian economy, and a continuing decline in funds allocated in yesteryears. India’s next door neighbor China spends some 2.4%, and both the US and UK spend either 3% or more per year.

It’s not like India doesn’t have illustrious or even seminal scientific contributions in the modern age. Scientific research did flourish in British India, amongst a few practitioners, benefitting from uninterrupted time in their laboratories with relatively cheap equipment– as with experimentalists such as Jagdish Chandra Bose and C.V. Raman; to name a few, or theorists including Meghnad Saha and S.N. Bose. Today though, these names remain largely confined to history in public discourse.

Science in pre-independent India

The imperial capital of science in India, Calcutta, was home to top-tier frontier research in quantum mechanics in the early 20th century. In the 1920s, Satyendra Nath Bose, a theorist, solved a particular problem related to the blackbody radiation law that evaded even Einstein. Bose, whom we profiled in our Know the Scientist page, fostered a collaboration with Einstein, culminating in numerous theoretical advances in quantum statistics, especially predicting the fifth state of matter, the Bose-Einstein condensate. Paul Dirac, the English physicist, coined the name bosons, after the class of quantum particles with integer spins, that Bose and Einstein’s statistics describe properties. It was one of these bosons (a word-play on “Bose-ons”) that particle physicists confirmed at the Large Hadron Collider (LHC) in Geneva, Switzerland in 2012.

Science during British India was top-notch, and continued its trend in the immediate aftermath of Indian independence. In 1948, Calcutta was abuzz again, but now with a cyclotron that they were building. A cyclotron’s a device that accelerates particles to near light-speed in the presence of electromagnetic fields, thereby producing radiation. It aided in frontier research in nuclear physics, for example, measuring cross-sections of the uranium nucleus (U-235). Housed at the Saha Institute of Nuclear Physics, accelerator physicists received funding to build a bigger cyclotron at the Variable Energy Cyclotron Centre, touching energies in the MeV range. Today, it’s part of the International Radioactive Ion Beam consortium, helping spread India’s fundamental research reach across the world.

So far, there’s been little coverage about the research in much of central universities and research institutions. It’s surprising how Bose’s contribution to quantum theory found no mention in India’s media discourse. Indian science hasn’t had limelight, not because there’s little research output – though there’s a case to make, as many has made before – but there’s a need for science communicators and journalists to help bridge that gap that exists between scientists and the public. The government has shown little consideration to extend science communication beyond publishing white papers about its importance.

Scientist or engineer?

Media representation of science is confused. The space program, that receives much public adulation and emblematic of national pride, is wrongly perceived as a scientific institution. Space engineers have become scientists in the public eye, despite rocket and satellite development is a matter of engineering, and not science. The former Indian president and “ISRO scientist” Abdul Kalam wasn’t a scientist per se, but an aerospace engineer. Barely mentioned in our public discourse are scientists that’ve done commendable research across the sciences.

Science done in central or local institutions for that matter hasn’t shared the limelight, anywhere as ISRO has since Independence. It’s the government’s pet, and has shaped narratives of technological innovation within and outside India. But this is largely technology history, without much scientific imperative.

Taking initiative

On the flip side, there’s much smaller science projects, that does combine the best of both worlds, combining technology development and science; thus blurring the dichotomy between applied and basic science research.

Govind Swarup, an Indian astronomer, worshiped by his peers as a “father of Indian radio astronomy” had voiced for a radio observatory, the first of its kind in Asia, to be constructed in the 1950s. The Indian government wasn’t interested, unless the astronomers received funds from sponsor countries. Australia had offered to pay and construct, after a long tussle, following which either party withdrew from discussions.

It was not until the 1980s, did India commence building an indigenous radio telescope. In 1995, the country’s first radio telescope, the Great Metrewave Radio Telescope (GMRT) was operational after a decade of construction. The team at GMRT contributed to the first detections of the cosmic gravitational wave background with its European radio astronomy counterparts in the Pulsar Timing Array project.

In 2016, the Indian astronomy community were greenlit to construct a gravitational wave detector in Pune, following confirmation of gravitational waves in February that year. Though this project too bas been plagued by successive delay construction would supposedly take off soon (perhaps late this year). In light of these late developments, politicians and scientists have begun beating the drums about the potential economic impact from involving Indian industry in the construction of the detector – utilizing state-of-the-art quantum technologies – in partnership with international teams. For the scientific community, precious data from the detector is incentive for attracting and inspiring the country’s emerging scientific talent.

Meanwhile, there’ve been hurdles that’ve prevented few other projects from taking off. The India-based Neutrino Observatory (INO), in Tamil Nadu, is one glaring example. Poor policy making amid environmental concerns that wasn’t addressed in time has forestalled construction for more than a decade. In this case rather, neither scientist nor policy maker bothered to engage with the public and hear out their concerns. And it takes much more development in science policies and public engagement to resolve these systemic issues.

The dawn of the artificial intelligence (AI) era is often compared to transformative technological advancements such as the steam engine, electricity, and the personal computer. These innovations reshaped industries and daily life, and AI is poised to make an equally revolutionary impact, particularly on global productivity. While the effects of AI are still unfolding, experts believe that its ability to significantly boost productivity could happen in record time—just seven years, compared to decades for earlier technological revolutions.

This optimism comes at a critical juncture in the global economy. Post-pandemic, many countries are grappling with stagnating growth, rising inflation, and mounting debt, alongside the fundamental issue of declining productivity. In fact, several international agencies have noted that the productivity decline following the global economic downturn is unprecedented in recent history. Yet, AI is emerging as a way of hope, offering the potential not only to reverse this trend but to propel productivity to unprecedented heights.

The Economic Impact of AI: A Long-Awaited Leap

The global economy has struggled with low productivity growth for over a decade. For example, U.S. labour productivity growth averaged just 1.68% from 1998 to 2007, a period during which significant technological innovations like the internet and personal computers began to take root. But since 2010, productivity growth has fallen further, dipping to 0.38% between 2010 and 2019.

Some forecasts suggest that generative AI alone could add between $2.6 trillion and $4.4 trillion to the global economy

In this environment, AI is seen as the key to unlocking a new wave of economic efficiency. According to recent reports from the International Monetary Fund (IMF), AI technologies are expected to drive a substantial increase in global productivity. Some forecasts suggest that generative AI alone could add between $2.6 trillion and $4.4 trillion to the global economy.

To understand the potential of AI in the context of productivity growth, it’s useful to compare it to previous technological breakthroughs. The steam engine, for example, took about 60 years to fully transform productivity in manufacturing. Personal computers accelerated productivity growth over 15 years. By contrast, AI is expected to have a profound impact on productivity within just seven years.

Generative AI and Its Promising Future

Generative AI is a form of artificial intelligence that creates new content—whether it’s text, images, or even software code—based on patterns learned from large datasets. The speed with which generative AI is advancing is extraordinary. ChatGPT, released in November 2022, was quickly followed by a more advanced version, GPT-4, and other breakthroughs have appeared throughout 2023. This technology is expanding rapidly, with the capability to process tens of thousands of words in a minute, creating a powerful tool for automating complex tasks.

The applications of generative AI are vast and varied. In the business world, AI systems are already transforming industries like customer operations, marketing, software engineering, and research and development. The banking sector, for example, is projected to see an annual revenue increase of $200 billion to $340 billion through the adoption of AI. The retail and consumer goods sectors could see similar gains, potentially adding up to $600 billion annually.

AI’s potential to automate routine tasks could also free up significant amounts of time for human workers. Studies indicate that generative AI could automate between 60% and 70% of the tasks currently performed by employees, dramatically increasing efficiency. For knowledge-based workers, particularly in high-wage and high-skill sectors, AI is poised to amplify productivity by reducing time spent on routine tasks, such as data analysis, customer service, and administrative work.

Transforming Labour Markets: A Double-Edged Sword

However, the rapid rise of AI is not without its challenges, particularly when it comes to labor markets. Many fear that the widespread adoption of AI could lead to massive job displacement, especially in developed countries where white-collar jobs are more susceptible to automation. According to the IMF, while 30% of U.S. jobs may be at risk of automation by AI, only 13% of jobs in India are likely to be affected, reflecting the differing technological capabilities and labor market structures across the globe.

At the same time, AI’s integration into the economy is expected to create new job opportunities, especially in fields that require advanced technical skills, such as AI development, data science, and cybersecurity. This pattern mirrors historical trends: when previous technological revolutions disrupted the labor market, they also created entirely new industries and job categories. A recent study by MIT found that 60% of the jobs in America today did not exist in 1940, highlighting the constant evolution of the labor market in response to technological innovation.

AI’s Role in Healthcare: Beyond Productivity

AI’s potential extends far beyond traditional sectors like manufacturing or finance. The healthcare industry stands to benefit greatly from AI’s ability to analyze vast amounts of medical data quickly and accurately. For example, AI systems can assist doctors by analyzing scan reports, identifying patterns, and recommending treatment protocols. AI can also reduce the burden of administrative tasks, such as summarizing doctors’ notes and processing insurance claims, thereby improving productivity in healthcare settings while also reducing costs.

Generative AI is now widely recognized as a general-purpose technology (GPT), similar to electricity or the personal computer

Such advancements could lead to significant improvements in healthcare delivery, making it more efficient and cost-effective. This would not only improve outcomes for patients but also contribute to economic growth by lowering healthcare costs for both consumers and governments.

The Path Forward

Generative AI is now widely recognized as a general-purpose technology (GPT), similar to electricity or the personal computer. These technologies have historically contributed to broad-based productivity growth across multiple sectors. The key to AI’s success as a GPT lies in its ability to integrate seamlessly with existing technologies and applications across various industries, driving continuous innovation and productivity gains.

The widespread adoption of AI in industries like logistics, manufacturing, education, and even creative arts has the potential to revolutionize how businesses operate and how workers contribute. As businesses continue to integrate AI into their processes, the resulting efficiencies will likely lead to increased competition, lower prices, and higher wages for workers in industries that embrace these changes.

AI’s transformative potential for global productivity cannot be overstated. Just as the steam engine and personal computers reshaped industries and economies, AI is positioned to trigger an unprecedented leap in productivity across nearly every sector. While challenges related to job displacement and economic inequality remain, the promise of a future in which AI drives substantial economic growth is undeniably exciting.

As AI continues to evolve, it is crucial for businesses, policymakers, and workers to embrace this change, adapting to new technologies and fostering an environment that allows AI to reach its full potential. The future of productivity is unfolding before us, and AI will be at the centre of this revolution.

In 1974, Xerox, a global leader in photocopiers, printers, and scanners, commanded a dominant 86% market share of copiers. However, by 1984, that share had plummeted to just 17%. At the same time, profits, which stood at $1.15 billion between 1980 and 1984, dramatically fell to only $290 million.

The company found itself grappling with fierce competition, not only from Japanese manufacturers but also from American rivals. As a result, Xerox began losing its once unchallenged monopoly. One of the key challenges was that Japanese companies, with production costs only 40-50% of Xerox’s, were offering superior products at competitive prices. Xerox, which had once reigned supreme in the copier industry, was now struggling to maintain its position. Faced with this difficult situation, it had only two choices: fight or surrender. Xerox chose to fight. But the question remained—how?

The company’s strategy was to closely study its competitors’ operations, from production methods to after-sales service, to understand why they were outperforming Xerox. By comparing each of their processes with those of their rivals, they identified the gaps in their own systems. Armed with this insight, Xerox implemented improvement plans across the board to enhance its processes and regain its competitive edge. This approach helped the company make a strong recovery and regain its footing in the market.

This approach is known as benchmarking—the practice of comparing one’s business processes with those of the best-performing competitors in the industry. The goal is to identify weaknesses and opportunities for improvement. For each function, every process is carefully compared with those of high-performing competitors. Xerox examined every component of its products, comparing them to those of superior offerings, to understand why their competitors’ products were better. They used this knowledge to systematically improve their own processes, ensuring they produced higher-quality products.

In the business world, observing and learning from top performers is not a sign of weakness but a strategic strength. By understanding what makes the best companies successful and striving to improve your own operations, you position your business for success. Benchmarking and adaptability are ongoing processes—businesses that continually evaluate and adjust their practices will thrive in a competitive marketplace.

The key to surviving and growing in a changing business environment is to embrace change. Hug the change, for it will keep your business alive and thriving.
