Landmark Study Finds Simple Toys Key To Boosting Educational Development And Meeting MDGs | January 2007


African youth need to play more according to a new landmark study published in the UK’s leading medical journal, The Lancet. The study tackles the high rates of illiteracy and educational under-achievement in Africa and finds that malnourishment and lack of stimulation are leaving millions unable to benefit from schooling. It found projects that encouraged learning through play led to children boosting their IQs and getting better reading skills. And it comes up with a very simple and low-cost solution – but excellent opportunity for entrepreneurs – toys and play.

“These are not high tech interventions,” said team leader for the study, Professor Sally McGregor of the Institute of Child Health of University College London. “Research over decades in Jamaica (and other countries) has shown that women with only primary school-level education and a few home made toys can be trained to make a significant difference in the education, intelligence and mental health of disadvantaged children. The Millennium Goal of universal primary education for all cannot be met unless these children’s poor development is tackled.”

The paper – Strategies to Avoid the Loss of Developmental Potential among Over 200 Million Children in the Developing World – is published in three parts in the journal.

Twenty projects around the world were evaluated for the benefits they produce for children under five who use toys. McGregor, who has set up several projects in Kenya, Tanzania and Uganda designing and constructing toys using whatever materials are available, was appalled by the widespread neglect of play throughout these countries. With play, the study found children read better, have better mental health and better self-esteem. In Africa it is ‘desperate, really desperate’ she says.

African primary school enrolments and literacy rates are among the lowest in the world, with over 42 million school children in sub-Saharan Africa not enrolled in school, and many children not able to afford to go or stay in primary school. Today a little more than half of African adults are literate and some 60 per cent of children go to school, according to UNESCO. The agency has forecasted the need for an additional 1.6 million teachers in Sub-Saharan African classrooms by 2015 – an increase of 68 percent.

The materials used to construct the toys do not need to be expensive or sophisticated. Toys can be constructed from banana trees, mud, corn on the cob, old plastic bottles, or cloth and straw dolls. It is key that the toys are safe for children under five and that anyone building such toys for sale must follow existing manuals.

McGregor continues: ‘One mother in a village was doing marvellous things with tiny scraps of material to make a doll. She received no recognition in the village for the work she was doing yet it was so important. It doesn’t take much – dolls or simple wooden blocks – they are so versatile. You see schools with nothing – it is unforgivable. The problem is how poor these people are – food just takes priority over toys – it is that stark.”

Locally produced toys are key to resolving this crisis for several reasons. Cost is the most important, with those most adversely affected also the least able to pay for toys and who are already living a precarious existence where basic survival takes precedence over play. Another factor is Africa being home to the countries who import the least number of toys: Somalia, Liberia, Togo, Rwanda and Chad. But the situation for African toymakers is often desperate as well, with many craft workers living at the economic margins. Several initiatives have emerged in the last couple of years to address this problem and ensure African toys are local and toymakers earn a living.

Initiatives like the African Toyshop based in Johannesburg, South Africa – a fair trade business – work to ensure African toymakers can make a living and get their wares to as wide a market as possible. The toymakers featured all use natural resources or recycled materials. Most work at the village level and produce toys that are culturally relevant to Africa. The organization COFTA – Cooperation For Fair Trade in Africa – is a network of Fair Trade producer Organizations in Africa involved and working with disadvantaged grassroots producers to eliminate poverty through fair trade. It is an excellent resource for grassroots organizations wanting to work with African toymakers.

The Dawn of the Genetics Revolution | 2001 - 2003

The Human Genome Project (HGP) was officially declared complete in 2003. A rough draft of the human genome sequencing carried out by the HGP was formally announced in 2000 and the completed sequence was announced in 2003. This breakthrough spawned many initiatives, including Iceland's deCode (below), and was reflected in the work I was called upon to undertake for the GOSH Child Health Portal at the time, such as designing websites for the London IDEAS Genetics Knowledge Park and the UK Newborn Screening Programme Centre (at bottom). I photographed the author of Our Genes, Steindor Erlingsson, in Reykjavik, Iceland for The Associated Press in 2002.

Feds call for AIDS, blood system inquiry: Some seniors infected

By David South

Today’s Seniors (Canada), July 1993

HIV-tainted blood transfusions given in the early 1980s have left some seniors with AIDS, but it is feared many are unaware of their HIV-positive status. 

Between 1979 and 1985 - before testing of blood products for HIV became mandatory - 266 transfusion recipients and over 677 hemophiliacs are known to have been infected in Canada, according to the Centre for AIDS Statistics. 

But the final numbers are unkown - estimates range from 400 to 1,000 cases of HIV transmission among the 1.5 million Canadians given blood products during this time. 

This uncertainty is fueling public concern. With such a serious public health danger, many are shocked by the confusing messages being sent by governments, the Canadian Red Cross Society and hospitals. 

But it took the report of an all-party Parliamentary subcommittee on health, released at the end of May, to shock the federal government into calling for a public inquiry into the blood system. The report is highly critical of the decision-making process involved in blood collection and distribution. 

“We have members of our group who are seniors,” says Jerry Freise, spokesperson for advocacy organization HIV-BT (Blood Transfusion) Group, whose wife was infected with HIV due to a blood transfusion. “And many of them went for years being misdiagnosed and treated for something other than HIV. Others have gotten sick, and one died without knowing it because nobody told him. 

“A classic case is Kenneth Pittman who was infected in 1984. The Red Cross found out in 1985 and they allegedly took two years to tell The Toronto Hospital. The hospital took two years to tell his doctor, and his doctor decided not to tell anybody. 

Infected

“Another couple, a lady of 59 and a man of 64, called us April 1. She found she was infected, and the reason she took a test is because her husband turned out to be HIV-positive three weeks before a transfusion in 1983. He had gone for years without a diagnosis from doctors.” 

This runs counter to the Red Cross’s story. 

“Whenever a blood donor tests positive for HIV antibodies, we go back and trace the prior donations,” says spokesperson Angela Prokoptak at the Society’s national office. “The Red Cross supplies blood to hospitals, so we know which units went to which hospital. But the hospital must go through their records to find who they transfused. 

“After identifying the recipient, the hospital contacts the recipient’s physician, and then they have them tested. There are of course limitations.

“Since 1987, the Red Cross has been advising people who may be concerned to consult their physician for counselling and advice.”

But subcommitte member Chris Axworthy, an NDP MP, found that hospitals and the Red Cross hesitated to notify former patients for fear of lawsuits. He says the federal government should show some leadership and stop passing the buck to other agencies and departments. 

Only two hospitals in Ontario - Toronto’s Hospital for Sick Children and Princess Margaret Hospital - have tried systematically to contact former patients. 

Ontario health ministry spokesperson Layne Verbeek says it is a laborious and costly task for hospitals to notify former patients. “We’ve always informed people if they are thought to be at risk, but many hospitals aren’t in the position to trace. If people are at risk or have doubts, they should be tested.”

Verbeek says recent media coverage has caused an increase in the number of people seeking HIV blood tests - requests for the test doubled after the Sick Kids hospital went public. The provincial government’s lab went from 700 tests per day to 1,300, but Verbeek says that has started to taper off. 

The ministry of health is happy with the number of people coming forward to be tested, says Verbeek. 

But Friese says the different players are more concerned about lawsuits than informing the public. He is especially upset at the Red Cross for not taking a leadership role in disseminating information. 

“The Red Cross and the medical system have failed miserably to contact people. Even today they are reticent to tell people they were part of a risk group and should get treated.” Friese feels the various governments and the Red Cross are leaving the job of informing the public to his group and the Canadian Hemophiliacs Society. 

Beat the drums

“It’s my job to beat the drums for the media while I’m dealing with my wife being infected? That’s my job, when these are the ministers of health?”, Friese says with anger.

The effect of AIDS on seniors isn’t new to US-based National Institute on Aging researcher Marcia Ory. She and colleagues helped sound the alarm back in 1989 with the book “AIDS In An Aging Society: What We Need To Know.” In the US, over 10 per cent of AIDS cases have occurred in people over 50. 

“Surprisingly, people have ignored older people and the AIDS issue,” says Ory. “You had older people in hospitals who might have complained about fatigue which was thought to be age-related. Older people aren’t as likely to be diagnosed as early because of the assumption that they are not at risk from AIDS.

“We don’t want older people in general to be overly fearful, but we want them to acknowledge the possibility, and to engage in good preventative practices if they are at risk.” 

Ron deBurger, director of AIDS prevention for the Canadian Public Health Association, would like assurances that the security of the blood supply has improved. 

“The subcommittee came to the right conclusion asking for a public inquiry,” says deBurger. “I would hope the terms of reference are broad enough to take a look at the whole issue of the safety of the blood supply, not only in terms of what happened in the past, but, more importantly, what’s happening today.”

Other than hemophiliacs, who require large quantities of blood, deBurger believes anybody who received one transfusion has a small risk. “If you had blood once, I think the odds are pretty long that you are going to end up with tainted blood. But AIDS does take eight to 10 years to manifest itself, and we might still be picking up pieces for the next four to five years that we don’t know about yet.” 

Friese recommends that anybody who received blood or blood products between 1979 and 1985 get an HIV test. If their doctor says it isn’t necessary, they should call the AIDS Hotline about anonymous testing. 

Anybody who has tested positive for HIV and would like support and counselling can call Robert St-Pierre of the Canadian Hemophilia Society at 1-800-668-2686.

For information on anonymous testing call the Ontario government’s AIDS Hotline in Toronto at 416-392-2437. For support write HIV-BT Group, 257 Eglinton Avenue W., Suite 206, Toronto, Ont., M4R 1B1.

India 2.0: Can the Country Make the Move to the Next Level?

New UNOSSC banner Dev Cha 2013

With the global economic crisis threatening to cause turmoil in the emerging markets of the global South, it is becoming clear that what worked for the past two decades may not work for the next two.

For India, the legacy issues of poverty still need to be addressed, and the country’s impressive information technology (IT) industry – which has driven so much of India’s growth – will face stiff competition from other countries in the global South. Some argue that if the IT industry hopes to keep growing and contributing to India’s wealth, things will need to change.

Unlike China, where heavy investment in infrastructure and a strong link between government and the private sector has driven the impressive manufacturing boom in the country, in India the government has de-regulated and taken a back seat, leaving the private sector and entrepreneurs to drive the change and do the innovation.

Many believe various areas need urgent attention if India is to continue to enjoy good growth rates in the coming years. Areas in need of attention include infrastructure, healthcare and education (thesmartceo.in), in particular the knowledge to work in the information technology industry of the 21st century.

One of the founders of Indian outsourcing success Infosys (infosys.com), executive co-chairman Senapathy Gopalakrishnan, told Britain’s Telegraph newspaper, “So many people’s lives have been changed by IT in India.

“People from the middle class and lower middle class have become global employees and have the opportunity to work with some of the best companies in the world. But the challenge for India is that this industry can only create so many jobs. IT is not going to solve the unemployment problem in India.”

But the coming next wave of change in information technology is an opportunity to be seized to reduce unemployment if enough people are educated to handle it.

According to Gopalakrishnan: “I strongly believe, and it’s backed up by data, that there is a shortage of computer professionals everywhere in the world, including India. The application of computers is growing dramatically and will continue to grow dramatically over the next 20 to 30 years. We have to train and create the workforce necessary to grow this industry.”

Various media stories have called this next phase India 2.0. If India 1.0 was the highly successful information technology outsourcing industry developed in the late 1980s, through the 1990s and 2000s, then India 2.0 is the next wave of IT innovation being driven by Big Data, automation, robotics, smart technologies and the so-called “Internet of things.”

Big Data is defined as the large amounts of digital data continually generated by the global population. The speed and frequency with which data is produced and collected – by an increasing number of sources – is responsible for today’s data deluge (UN Global Pulse). It is estimated that available digital data will increase by 40 per cent every year. Just think of all those mobile phones people have, constantly gathering data.

Processing this data and finding innovative ways to use it will create many of the new IT jobs of the future.

“We are living in a world which is boundary-less when it comes to information, and where there is nowhere to hide,” continues Gopalakrishnan, “If you have a cellphone, somebody can find out exactly where you are. Through social networks you’re sharing everything about yourself. You are leaving trails every single moment of your life. Theoretically, in the future you’ll only have to walk through the door at Infosys and we’ll know who you are and everything about you.”

Unlike in the late 1980s, when India was the pioneer in IT outsourcing for large multinational companies and governments, competition is fierce across the global South. The mobile-phone revolution and the spread of the Internet have exponentially increased the number of well-educated people in the global South who could potentially work in IT. China, the Philippines, Kenya, Nigeria and Ghana are just some of the countries heavily involved in this area.

If India fails to meet the India 2.0 challenge, it risks seeing its successful companies and entrepreneurs leaving to work their magic elsewhere in Asia and the new frontiers of Africa, just as many of its best and brightest of the recent past became pioneers and innovators in California’s Silicon Valley.

India’s IT sector contributed 1.2 per cent to the country’s gross domestic product (GDP) in 1998; by 2012, this was 7.5 per cent (Telegraph). The IT industry employs 2.5 million people in India, and a further 6.5 million people indirectly. IT makes up 20 per cent of India’s exports and, according to the National Association of Software and Services Companies (nasscom.in), the industry has revenue of US $100 billion.

India is now the IT and outsourcing hub for more than 120 of the Fortune 500 companies in the United States.

Out of India’s 3.5 million graduates every year, 500,000 are in engineering – a large pool of educated potential IT workers. India produces the world’s third largest group of engineers and scientists, and the second largest group of doctors.

IT has become a route that catapults bright Indian youth into 21st-century businesses and science parks and to the corporations of the world.

One visible example of the prosperity brought by IT services in India is the booming technology sector based in the city of Bangalore (also called Bengaluru) (http://en.wikipedia.org/wiki/Bangalore).

Reflective of the contradictions of India, Bangalore has 10 per cent of its workforce now working in IT, but also 20 per cent of its population living in urban slums.

The nearby Electronics City (elcia.in) is considered “India’s own silicon valley and home to some of the best known global companies.”

To date, aspects of India 2.0 are already taking shape.

One company is called Crayon Data (crayondata.com). It uses Big Data and analytics to help companies better understand their customers and increase sales and deliver more personal choices.
Edubridge (http://acumen.org/investment/edubridge/) is helping to bridge the gap for rural youth with varied education backgrounds and long-term jobs. Edubridge trains youth for the real needs of employers to increase the chances they will get a job. This includes jobs in the IT business process outsourcing sector and banking and financial services.

Infosys is working on innovations for the so-called “Internet of things,” in which smart technologies connect everyday items to the grid and allow for intelligent management of resources and energy use. Infosys is developing sophisticated software using something called semantic analytics – which analyses web content (http://en.wikipedia.org/wiki/Semantic_analytics) – to sort through social media and the Internet to track customer responses to products.

Elsewhere, former Infosys Chief Executive Nanden Nilekani is involved in a Big Data innovation to address the problem of social and economic exclusion of India’s poor. Called Aadhaar (http://uidai.gov.in/), the government-run scheme is gathering biometric data on every Indian to build the world’s largest biometric database. After being enrolled and having fingerprints and iris scans taken, each individual is given a 12-digit identification number. So far 340 million people have been registered with the scheme, and it is hoped 600 million will be registered by the end of 2014.

The idea is to use a combination of access to mobile phones and these unique ID numbers to widen access to all sorts of products and services to poor Indians, including bank accounts for the millions who do not have one. Many people, lacking any identity or official acknowledgment they exist, were prevented from engaging with the formal economy and formal institutions. Being able to save money is a crucial first step for getting out of poverty and it is hoped information technology will play an important role in achieving this.

Mobile Phone Microscopes to Revolutionize Health Diagnostics

 

 

Mobile phone usage has increased hugely across the global South in the past five years. In Africa, the number of mobile phone subscribers reached 545 million in 2013, while there are 3.5 billion mobile phone users in Asia and the Pacific (ITU). Some 93 million people in Africa and 895 million in Asia and the Pacific have mobile phone Internet access (ITU).

“Every day we are moving closer to having almost as many mobile-cellular subscriptions as people on earth,” Brahima Sanou, Director of the ITU Telecommunication Development Bureau, wrote in its latest report on their growth.

The number of mobile phone subscriptions in the developing world has surpassed 5 billion and the number in the world as a whole reached 6.8 billion in 2013 (ITU), out of a world population of more than 7.1 billion. This compares to considerably lower numbers of people with access to the Internet: 2.7 billion in the world (ITU).

While many people in poorer countries have basic versions of mobile phones, the next generation of smartphones has been growing in number as prices come down (http://en.wikipedia.org/wiki/Smartphone). Examples of these smart phones include the BlackBerry, Apple’s iPhone, the Samsung Galaxy, and the Nokia Lumia. Smartphones tend to have enormous computing power and an ability to run complex ‘apps’ or applications – including public transport options, maps, restaurant and store locators, banking services and market information and resources. They can also access the Internet through Wi-Fi, and have camera and video capability.

What people can do with these feature-packed phones is limited by little other than human imagination. With the ability to store large amounts of data and images, using apps that perform a limitless range of services and tasks, smartphones can be deployed as powerful tools to tackle problems.

Science fiction sagas have long fantasized about people being able to walk around with small electronic devices that can do immensely powerful tasks, including being a medical diagnostic tool. But this science fiction dream is rapidly becoming reality in the global South.

Various initiatives and innovators are using mobile phones and smartphones to conduct medical diagnosis and gather data for medical studies in real time.

Some innovations are even turning smartphones into mobile microscopes.

Developed by the University of California, Berkeley in the lab of Professor Daniel Fletcher (http://cellscope.berkeley.edu/), the CellScope (cellscope.com) is capable of turning the camera on a cell (mobile) phone into a diagnostic microscope with a magnification of 5x to 60x. Fletcher’s lab has also pioneered work on needle-free injection technology.

The CellScope can be used for ocular imaging (technologies for visualizing and assessing a range of diseases of the eye) and for detecting tuberculosis, blood-borne diseases and parasitic worms.

Fletcher is a bioengineer and was impressed with how much mobile phone technology has proliferated across the global South.

“You don’t have to put in these copper wires (for phone lines) anymore; you have the (cell) towers. It’s big business,” Fletcher told The Scientist Magazine.

“It’s leaping over the need for infrastructure.”

Fletcher and his colleagues experimented by attaching extra lenses to smartphones. They then used the phone to image cells that had been stained with fluorescent dyes to make them easier to see. The quality of the image was so good, they were able to diagnose malaria from blood samples and tuberculosis from sputum (spit) samples.

With the addition of image analyzing software, the phone was able to automatically count the number of Mycobacterium tuberculosis bacilli. They were trying to prove you did not need conventional microscopes to do this sort of diagnostic work.

Fletcher and his colleagues are currently trialling the technology in Vietnam, India, Cameroon and Thailand.

“Technology alone doesn’t create effective health care,” Fletcher emphasizes. “It’s got to be part of a context in which the information is captured and validated and is analyzed in the right way, and treatments are then available in response to information.”

Another group from Toronto General Hospital in Canada (http://www.uhn.ca/corporate/AboutUHN/OurHospitals/Pages/TGH.aspx) has ‘hacked’ an iPhone smartphone by placing a 1 millimeter ball lens on the phone’s camera. Isaac Bogoch, an infectious disease specialist, had been investigating parasitic worm infections in children on Pemba Island off the coast of Tanzania. Along with Jason Andrews of Massachusetts General Hospital, they had been inspired by a report about how a team of researchers from the University of California, Davis had created a simple microscope out of an iPhone with a 1 millimeter lens. This makeshift microscope was used to take pictures of blood smears at a 350 times magnification and giving a 1.5 micron resolution.

“We thought that was a great idea,” Bogoch told The Scientist Magazine. Bogoch regularly works as part of an international team around the world, often in remote locations.

“We thought … we could take it to the field and see if it accurately works in a more real-world setting.”

Inspired, Bogoch got together with his colleagues and created a similar microscope with a 3 millimeter ball lens and then got to work using it to identify soil-transmitted helminth eggs in stool samples in Tanzania. When examining the stool samples of 199 children in a clinical trial using the makeshift microscope, they were able to accurately identify helminth infections in 70 per cent of the cases. They also found the iPhone microscope did very well at spotting eggs of particular parasites, such as 80 per cent of Ascaris lumbricoides infections (http://en.wikipedia.org/wiki/Ascaris_lumbricoides). The success rate dropped significantly, however, when trying to detect whipworm parasites (just over half) and hookworm infections (14 per cent).

But this is early days and an experiment: “Obviously the results aren’t perfect and there’s definitely room for improvement,” Bogoch admits.

What stands out is the potential to completely revolutionize health care by continuing to develop the capability of smartphones. With their portability and low cost, they also have the advantage of not needing a trained physician to operate them, according to David Walker, president of the American Society of Tropical Medicine and Hygiene, in The Scientist Magazine.

One of the many advantages of combining a microscope with a digital smartphone is the ability to take a picture and send it straight away to someone to make a diagnosis.

Even more exciting, Sebastian Wachsmann-Hogiu at the University of California, Davis (http://cbst.ucdavis.edu/people/sebastian/) is adapting mobile phones to undertake spectroscopy (http://en.wikipedia.org/wiki/Spectroscopy), using diagnostic test software to analyze samples on the spot. This, when successful, would be akin to the capabilities first mooted in the science fiction television and film series Star Trek (startrek.com). In Star Trek, the doctor is able to use a small handheld digital device to quickly diagnose what ails somebody.

The potential for this technology in the global South is significant. Aydogan Ozcan at the University of California, Los Angeles, who is also working on mobile phone microscopes, believes this is as significant as the dawn of the personal computer: “If you look at the early computers, they were bulky, they were extremely expensive,” he says.

But now computers “are portable … and almost anyone can afford them. The same thing is going on today (with microscopy). We are miniaturizing our micro- and nano-analysis tools. We’re making them more affordable; we’re making them more powerful.”

It looks like this science fiction dream will soon become today’s reality.
