11.1 The end of shop class  (9/2/2012)


THE END OF SHOP CLASS

The retirement of the Baby Boomers, aged 48 to 66, who started working in factories in the 1960s, '70s and '80s, is accelerating the problem. They grew up in a world where children amused themselves by building go-carts and tree houses, rather than by playing video games and texting friends.

As U.S. manufacturers cut their headcount by 40 percent over the past three decades to the industry's current 12 million workers, they created a supply of experienced yet unemployed or underemployed people who could step into vacant factory jobs. But those people are now reaching retirement age.

One reason the experienced Baby Boom manufacturing workers will be so hard to replace is that the high school shop classes where many of them learned their skills were phased out in the 1980s and 1990s, said Emily DeRocco, president of the Manufacturing Institute, the educational arm of the National Association of Manufacturers.


"We have very falsely silo-ed education and workforce training, resulting in ... an educational system that really doesn't care about the ability to get a good job," said DeRocco, who served as assistant secretary of labor and employment in the administration of President George W. Bush.


The shop classes where generations of Americans learned to make birdhouses and other simple projects were eliminated as educators focused more on learning to use computers than hand tools. Today, manufacturers are trying to swing the pendulum back part way -- teaching students to use computer-controlled motors to power a simple machine in a high school class offers some preparation for running a high-speed production line.


11.2 Story telling, should it precede the three Rs?  (1/4/2012)

On weekends I make trips too and fro between Nagercoil and Trivandrum, a distance of 70 Km, by a lumbering passenger train. For the two hour trip (four hours up and down) I usually purchase two business magazines: wish I could find something better to read, something which tells us how our many looming problems will be solved; for the moment business magazines provide the best pointer to where the action is - alas! I also read novels (life would lose half the fun without novels :-)

What disturbs me is that, I seem to be the only person in the train reading anything; there are a lot of office goers in the train and on the return trip I find many youngsters, probably studying in the mushrooming engineering colleges, mostly fiddling with their cell phones. I do not wish that everyone should turn into bookworms, yet, would it not say much for our educational system if at least 10% of the passengers were reading something. Are we living in such a boring world that there is nothing new to wonder about?  

Why is it that a child, who learns so much on his own by the age of three, find his education literally coming to a grinding halt when he joins school. The problem could be, we are trying to educate our children without providing a context in which learning can take place. And our modern day Gurus, telling us that we need to educate ourselves so that we can compete effectively in the market place enthuses neither the teacher nor the student. 

My suggestion is that we introducing extensive story telling as the first step to formal education. Story telling should also form the medium through the three Rs are taught. Stories can be of the following kind: religious, cultural, the story of the world we live in - past, present and future -  funny stories, biographies, etc.. Obviously, the stories should be different for children having different backgrounds. 

To summarise:

- Language (which a child naturally learns)
- Story telling in this language.
- Learning of the three Rs based on stories.

11.3 Why common engg entrance bothers IITs  (26/5/2012)

 A major problem with the educational system in India at present is the competition between CBSE, ISC, and State Boards, to award higher marks to their students. This converts education into a 'mugfest' with students routinely scoring above 95% marks.
Solving this problem is very easy: does not involve spending 1000s of crores of rupees.

1. Make the examinations sufficiently tough so that few score above 80% . (Since there is great political pressure for children to perform well, the exams may be made sufficiently easy so that most students are able to score 50% marks).

2. Shift to grading system in all classes, do not disclose actual marks:

S ... above 90 ?
A+ ... 71 to 90 ?
A ...  60 to 70 ?

Advantages with grading system:

1. Parents will not be after their child asking why he scored 81 while Ashok down the road scored 81.5. In short, it will prevent mayhem in families.
2. Parents will be more relaxed, they may even encourage their wards to engage in extracurricular activities.
3. Parents will feel less pressure to send their wards for tuition, starting from class 1.
4. Teachers will begin to relax and make their teaching more interesting.

Why common engg entrance bothers IITs

Anubhuti Vishnoi : New Delhi,  25 May 2012,

The HRD Ministry’s ambitious proposal to replace multiple engineering entrance examinations including IIT-JEE with a single, common entrance in 2013, with weightage given to school board scores, has become a subject of debate not only between the IITs and the government but also within the IITs.
The directors of the 15 IITs are largely in agreement with the idea of the common entrance exam and percentile-based normalisation of scores across school boards. Faculty federations and senates in most IITs, however, are against it. Only one IIT — Guwahati — has unanimously endorsed the proposal. And the senates have near-vetoed the introduction of the common entrance test in 2013.
Ahead of an IIT Council meeting next week, here are the proposal’s varied aspects and the areas of conflict.
The test
Initially called the Indian Science Engineering Eligibility Test, the Common Entrance Test has been proposed from 2013, replacing the AIEEE and the JEE. Under the proposal, the exam would be of two parts, Main and Advance, each of three hours. Main, which would be objective type, would test students for comprehension, critical thinking and logical reasoning, while Advance would test their problem-solving abilities in the basic science subjects.
A minimum of 40 per cent weightage to Class XII board exam scores has been proposed to determine admission; each state government or institute would be able to decide the specific weight it gives to board, Main and Advance scores. A committee headed by Dr T Ramasami, secretary in the Department of Science & Technology, has demonstrated with the help of the Indian Statistical Institute that school scores across various boards can be normalised through a statistical process.
For
The HRD Ministry and supporters of this proposal including IIT directors point out that students coming into the IIT system through JEE are now no longer as exceptional and talented as before. Pointing fingers at the coaching lobby, they say students clearing JEE are doing so on the basis of rote learning and with little “raw intelligence”.
This, they argue, is also because students are so focused on their coaching classes that they neglect their school lessons. With a new common entrance exam, they argue, not only will the stress of appearing in multiple entrance exam disappear but school-level teaching and learning will also get back its due attention and, consequently, bring in students with a well-rounded intellect into the IIT system.
Against
The IIT senates across institutes are not convinced that scores across several state boards can be normalised effectively by the statistical methods cited. They refuse to accept the 40 per cent weightage given to school boards.
The senates have instead proposed that the JEE/common entrance exam be converted to a two-stage exam: Main should be used to screen applicants for those who should appear for the JEE test to seek admission into IITs. This JEE test and its nature, they say, must be the sole prerogative of the Joint Admission Board, provided the number of students screened to appear for JEE is small enough. A subjective format should be followed for it, they have insisted.
IITs’ take
Normalisation of board scores: Normalisation using percentile approach should be researched further with data available for other boards and 2012 results of all boards.
On 40% weightage: Percentile marks should be used as an eligibility criterion or admission to IITs should be strictly based on JEE. JEE, in turn, should be as decided by JAB. Board marks in percentile form may be used as an eligibility criteria along with the Main paper marks of a common national test.
Main: IITs would like to use the Main results as a screening criterion. However, this process may begin from 2014 and not 2013.
Advance: No, IITs should have their own JEE paper. This paper may be subjective in nature. Eligibility for JEE should be restricted based on Board marks in percentile form and Main marks.


11.4 Learning calculus at the age of six  (27/5/2012)

Shouryya Ray worked out how to calculate exactly the path of a projectile under gravity and subject to air resistance, The (London) Sunday Times reported.
The Indian-born teen said he solved the problem that had stumped mathematicians for centuries while working on a school project.
.. Mr Ray's family moved to Germany when he was 12 after his engineer father got a job at a technical college. He said his father instilled in him a "hunger for mathematics" and taught him calculus at the age of six.

11.5 Divided House - IIT alumni  (7/6/2012)


Divided House
THE IIT alumni are quite offended at the idea of changing the entrance exams for the IITs. A few alumni associations have decided to petition the courts against the move to introduce a common entrance examination for all the engineering colleges. However, they are finding themselves up against another set of IIT alumni, serving within the government, who happen to be pushing for the introduction of the new system. One of them is V Umashankar — private secretary to HRD Minister Kapil Sibal — a Haryana cadre IAS officer who has an IIT background. CBSE chairman Vineet Joshi is another. An alumnus of IIT Kanpur, Joshi is a supporter of the move to give weightage to school marks in IIT entrance. However, there is one whose heart lies on the other side of the fence. Apurva Chandra, a joint secretary in the HRD Ministry, is BTech and MTech from IIT Delhi and is no fan of the new entrance format. At a recent meeting of school boards, Chandra is learnt to have expressed his doubts over the move to give weightage to school marks but apparently has been won over by Joshi’s arguments.
   
-------------
The main question is one of autonomy. Are the IITs autonomous or are they not autonomous?

The best way to ruin an institution is to take away its decision making powers; people who do not take decisions for themselves will pass on the buck for nonperformance to others. This applies to all institutions, let alone the IITs which we are given to understand already have a high degree of autonomy build into their management structure.

11.6 Harvard Business School Mumbo Jumbo  (23/6/2012)


Come on, guys! This isn’t what your parents thought you’d do with your expensive education. Find something real.

Solve the euro crisis. Eliminate insider trading. Do a study on whether recycling plastic bottles is worth the effort.

11.7 The problem of different boards  (29/6/2012)

 In deciding on a common all India engineering exam it is worth keeping in mind that the syllabi, the structure of text books and teaching and learning methodology vary greatly from board to board. If you wish to get through AIEEE, it is advantageous to have studied in CBSE, because CBSE teachers probably set the AIEEE exams. If you have studied in ISC, or studied in a state board, AIEEE may not be straight sailing for you.

You may think that an ISC or CBSE student could easily write the Tamil Nadu state exam. Not so. You would need to know the Tamil Nadu approved text books practically verbatim (a feat for students who are not used to rote learning). In fact an ISC or CBSE student attempting this adventure would not score that high in the Tamil Nadu exam.

Now, with the common All India Exam, to be set by CBSE, we are simply handing over the advantage to the CBSE board and the CBSE students.

As the matter presently stands:

* AIEEE is biased towards CBSE.
* IIT - JEE may not be biased towards any particular syllabi.
* The state boards have their own individual biases that cannot be easily cracked by CBSE and ISC students.

Unless an attempt is made to make all the systems uniform, which is not easy to do, considering that ISC provides good English Language and English comprehension skills, CBSE where English Language skills are less honed, and the state boards that have their own agenda, it is pointless to have a common all India exam.

So far as IITs are concerned, my feeling is, if two exams are required, both should be controlled by the IIT system. Handing over one exam to the CBSE system impinges on the autonomy of the IITs.

With the entry of private players and overseas institutions; and the plain jealousy of all, there is a move to cut IITs down to size :-)

Selvaraj

P.S. It is irritating to use the word syllabi (why not use syllabus as both singular as well as plural forms?)

11.8 Messing up education  (30/6/2012)


 Rather than looking into the fundamentals of schooling the ministry is trying to use an entrance examination as a means of improving the standard of schools.

11.9 HRD's Plan to Launch Education Channels Hits Roadblock (1/7/2012)

An ambitious plan of the HRD Ministry to launch 1,000 educational television channels has hit a roadblock after it failed to get the required permission from the Information and Broadcasting Ministry.

The HRD Ministry had first initiated steps to launch 50 round-the-clock channels and had approached the I&B Ministry for permission for uplinking and downlinking the channels.

11.10 Marketing principles / Engineering education (8/7/2012)
IGNOU offers distance learning courses in management that are structured to meet the needs of various aspirants http://www.ignou.ac.in/upload/management-2011-12.pdf. If you study and pass exams in 32 subjects you obtain a MBA. Studying five subjects you obtain a Diploma; with eleven, you obtain a Post Graduate Diploma in Management.

When I took this course in the later half of the 90s, I was particularly interested in the mysteries of Marketing; at that time this course was offered at the PGDM level, so I signed up for this course. ( I ended up passing in seven subjects and obtained a Diploma, five subjects short of PGDM; by which time I had lost interest )

My main objective of probing the mysteries of Marketing was however met. Marketing is organised around the 4P principle.

Product
Price
Promotion
Place

In designing a product there is also an important concept of product differentiation http://en.wikipedia.org/wiki/Product_differentiation

In economics and marketing, product differentiation (also known simply as "differentiation") is the process of distinguishing a product or offering from others, to make it more attractive to a particular target market. This involves differentiating it from competitors' products as well as a firm's own product offerings.
http://en.wikipedia.org/wiki/Product_differentiation

How smart GOI is in understanding such issues is highlighted in the study material sent to me by IGNOU:

Birth Control; criticism levelled by Nathaniel Martin:

"Selling birth control is as much a marketing job as selling any other consumer product. And where no manufacturer would contemplate developing  and introducing a new product without a thorough understanding of the variables of the market, planners in the highest circles of Indian Government have blindly gone ahead without understanding that marketing principles must determine the character of any campaign of voluntary control. The Indians have done only the poorest research. They have mismanaged the distribution of contraceptive devices. They have ignored the importance of 'customer service'. they have proceeded with grossly inadequate undertrained staff, they have been blind to the importance of promotion and advertising."


Now, on the issue of the future of the IITs, we see a similar lack of thought and analysis. Is there no product differentiation between the IITs, NITs and the state run engineering colleges? Are the NITs funded to the same level as the IITs are? If the IITs are so low in standard as many claim, why start so many new IITs?

As I see it there is considerable product differentiation between the IITs, NITs and the state run colleges. Had the central government understood this product differentiation, they would not have rushed to start more IITs, probably they would have invested money in starting additional NITs. I don't know how GOI visualises the role of IITs, other than being milch cows for their political ambitions :-) My views would be as follows:

IITs - more heavily funded, to provide leadership in engineering education. Students should have wider knowledge of the engineering discipline as a whole. More mathematical orientation required etc.

NITs - focus more on turning out practical engineers.

State run engineering colleges - No one stops them from aiming for the above objectives, but of late we find the state governments diluting standards to focus on social inclusion, which is a commendable objective in itself.

It is undesirable and uneconomical however to attempt to make Einsteins out of everyone. We need a few Einsteins, who from their high pedestals can pull the others up. Trying to cut all the grass to the same height however is a self-defeating policy.

(The IITs and the NITs may not be meeting the above stated objectives. Then we should focus on solving the shortcomings; cutting all the grass to the same height is not the solution to the problem).

.....

I would strongly recommend PGDM from IGNOU for all government functionaries!

Incidentally, you need fairly good grasp of English to understand the study material sent by IGNOU. Since our educational system trashes any attempt to learn a language properly, I wonder about the future of education in India.

I had a quick glance at  'The Chennai Declaration' http://www.samacheerkalvi.in/pdf/Chennai_Declaration_Pre-final_01July2012.pdf, posted by Dr. V.N.Shrma. The emphasis put on education in the mother tongue is commendable. We may however keep in mind that:

1. A language is incomplete without its literature.
2. It is important for an educated individual to have good command of at least one language (increasingly, I am given to understand, students have poor command of their mother tongue, as well as English)
3. It is important, if we are encouraging local languages, to translate be best of world literature into these languages.
4. To be truely inclusive at least some institutions of higher learning should impart instruction in the local languages.
5. Is it so difficult to make everyone proficient in a local language and in English. In pre-independent India, educated people seem to have had good command of two languages.

11.11 IIT-JEE format a boon for coaching schools (8/7/2012)
The idea of the Ministry of Human Resource Development (MHRD) to tweak the joint entrance examination (JEE) to discourage the coaching culture has done exactly the opposite so far.
Coaching institutes Business Standard spoke to said, with the MHRD insisting on inclusion of board marks as an eligibility criterion for admission to the IITs, admission to their programmes has gone up, and, in some cases, more than doubled. “After Board examinations have been made a part of the admission procedure at IITs, enrolments for this year have more than doubled. There are about 1,200 students enrolled (for the 2014 exams), compared to 575 students last year. Further, the level of examination will get difficult now as CBSE will set the JEE Main paper. Students and parents have understood that it will be difficult to get into the premier institutes without formal coaching," said Chandan Dikshit, planning and strategy head at Rao IIT Academy, an IIT-JEE coaching institute. JEE is the qualifying examination for admission to the Indian Institutes of Technology (IITs).

11.12 The IITs were formed to produce world-class engineers and scientists   (15/7/2012)


Engineering seems to be one of the few fields where there is no compulsory internship like in medicine, law and CA. This is one of the reasons why students may not be fully aware of the beauty and possibilities of engineering.
Engineering is also a field which is like a joker in a pack of cards. The graduates fit into any career! Naturally, the student will graduate into a more lucrative/easier career. Would a barrier to this help in getting committed students?

11.13 Education Is Too Vital to Be Left to Educators (19/7/2012)
Time Magazine in May ran an article entitled, “Learning that Works.” Basically it speaks about how a vibrant vocational education program can be an “alternative way to teach math, science and reading.” Vocational education basically went away 40 years ago because it became a civil rights issue. The education community’s theology was “That every child should go to college.” We have found out the establishment didn’t know what it was talking about. They conned students into taking courses which produced no real education and cost thousands of dollars.
Today Vo-Tech and community colleges are teaching subjects students enjoy and can earn a living from. Examples would be a dental hygienist at $68,300, radiology technician at $54,300 and registered nurse at $64,700, according to the Time story. Reforms are coming because they must. We have left perhaps the most important task in America to people who haven’t delivered.

11.14 Can this be true? (3/8//2012)
Experts estimate that an Indian Class VIII student is at the same level as a South Korean Class III student in math abilities or a Class II student from Shanghai when it comes to reading skills. Elementary education is a fundamental right in India, but clearly that says nothing about what our children are studying in school every day.

I think our nation needs to know more. How were these students selected? From which schools? Were children from village schools in India pitted against students from elite schools in other countries? Our media needs to report in a more comprehensive way.

11.15 Anyone worried about what's wrong with our education? (5/8/2012)


Shouldn't we seek alternatives? Can we reduce the wage disparity between those who work with their hands and those who do 'mental' work? How do we bring about dignity of labour in this country? A Japanese guru of quality spoke about the "joy of sweating". Our society, too, had that joy. Why did we lose it to the pleasure of air-conditioned offices to do dumb jobs? Can we nurture those who enjoy working with their hands and not force them to learn by rote? How can we enable each individual to pursue an occupation according to one's aptitude?

11.16 Do Romanian schools produce idiots :-) (7/8/2012)
While the state-funded system is facing financial problems, some private universities in Romania are making a huge profit. Also known as “diploma factories”, these institutions are enrolling a large number of students each year. The quality of education in these private establishments is usually even lower than in the state system. Many of their graduates end up unemployed.

11.17 Little knowledge is a dangerous thing (22/8/2012)
I have just started to read the famous science fiction writer, Issac Asimov’s autobiography. This is what Asimov has to say on Literacy: “The age of the pulp magazine was the last in which youngsters were forced to be literate. True literacy is becoming an arcane art, and the nation is steadily ‘dumbing down.’”
Asimov on his school experience: “Once I could read, and as my ability to read improved rapidly, there turned out to be a serious problem. I had nothing to read. My schoolbooks lasted me only a few days, I finished every one of them in the course of the first week of the term and thereafter was educated for that half year. The teacher had very little to tell me.”
……………
Issac Asimov’s life experience has got me wondering. Do modern humans know enough to safely drive forward a complex civilisation without going over the cliff? What kind of intelligence and knowledge does our society need? How should we educate our children to meet this need? This is what I visualise for our nation of more than a billion people:
1000 – The number of persons we need of the caliber who could win Nobel Prizes. It is quite possible we may already have 100 such people (they may not however be getting the required opportunity to shine). Since they will probably be super specialists, we cannot however hand over the reins of the Nation to them (sigh)!?
10000  – The number of people we need with very wide ranging knowledge. We would expect these people to be widely read, well informed and capable of true interdisciplinary thinking. We would expect such individuals to naturally (not by passing competitive exams), take over the reins of leadership.  My fear is that our present educational system may be creating only a handful of such people. It will be impossible for the regular school curriculum to create such individuals because of the inherent inefficiency build into the system, where teaching is more – of the teachers, by the teachers and for the teachers :-)
Let us focus our interest in the second categorie of individuals. Can we set up special schools where children are not taught in the regular sense, but allowed to acquire knowledge (of diverse kind) at the speed at which they are capable of acquiring it???

11.18 Issac Asimov's travails in academia (extract from his autobiography) (7/9/2012)


1. WRITING PHD THESIS

... I was sitting at my desk, preparing the materials for the day's experiments, and brooding over the approaching necessity of writing a doctoral dissertation. A doctoral dissertation is a highly stylized document, and ironclad rules necessitate that it be written in a stiff and abnormal (even stupid) way. I did not want to write in a stiff, abnormal, and stupid way.

It struck me, therefore, in a Puckish moment, to write a spoof of a doctoral dissertation that would relieve my soul and enable me to approach the real thing with more spirit.

As it happened, I was  working with tiny feathery crystals of a compound called catechol, which was extremely soluble in water. As I dumped some of it into the water, it dissolved the moment it hit the surface. I said to myself, "What if it dissolves just a split second before it hits the surface. What then?"

The result was that I wrote a pseudo-dissertation written as stodgily as I could manage about a compound which dissolved 1.12 seconds before you added the water. I called it The Endochronic Properties of Resublimated Thiotimoline.

I submitted it to Campbell, who enjoyed it and who had no objection to running an occasional spoof article. I realized that it would appear in the magazine at just about the time I would be taking my make-or-break doctor's orals, and I was cautious enough to instruct Campbell to run it under a pseudonym.

It appeared in the March 1948 ASF and Campbell forgot about the pseudonym. There it was, Isaac Asimov plastered all over it, and, of course, the entire Columbia University chemical faculty got wind of it and passed it from hand to hand.

I turned really sick. I knew what would happen. Whatever I did at the doctor's orals, they were going to turn me down on the grounds of personality deficiency. All those years, all those years, and I was going to lose out for the old, old crime of irreverence to my superiors.

But it did not work out that way. After the professors had put me through the hell of a doctor's orals, Professor Ralph Halford asked the last question: "Mr. Asimov, can you tell us something about the thermodynamic properties of resublimated thiotimoline?"

I burst into hysterical laughter, because I knew they wouldn't play games with me if they intended to flunk me, and they didn't. I passed, and one by one they emerge from the testing room, shook my hand, and said, "Congratulations, Dr. Asimov."


2. ISAAC ASIMOV WAS A POOR RESEARCHER BUT A SUPERLATIVE LECTURER.

As my research continued to decline, my lectures continued to improve. By the time my active period at the medical school was drawing to its end, I was generally recognized as the best lecturer in the school. The account reached me, in fact, of two faculty members talking in one of the corridors. The distant sound of laughter and applause reached them, and one said, "What's that?"

The other replied, "It's probably Asimov lecturing."

My utter failure at research didn't bother me in the least, considering my excellence in lecturing. I reasoned it out this way. The prime function of a medical school is to teach medical students to be doctors and one important way of  doing this is through lectures. Not only was I capable of informing and educating the class with my lectures but I roused their enthusiasm as well.

The proof of that was their reaction to my lectures. It was customary to applaud each professor at the conclusion of his final lecture of the course. It was, of course, applause that was halfhearted and perfunctory, the product of custom rather than of conviction. I alone would get applause in mid-course lectures, and real applause too. And while that took place, I felt invulnerable.

How wrong I was! I had left one factor out of my calculations. Lecturing helps only the students. Research, on the other hand, means government grants, and a portion of the grants is invariably marked for "overhead," which goes to the school. What it amounts to is that the school chooses research over lecturing every time - money for itself over education for its students. That meant I was not invulnerable at all, but rather a sitting duck once my research vanished altogether, which it did.

You might argue that the school was correct in choosing itself over the students, since if the school were forced to curtail its facilities through lack of funds, the students would suffer. On the other hand, surely one could strike a balance. A superior teacher might be forgiven failure at research. That, however, as I shall explain later, was not to be.

3. FIRED!

... One postscript - In the spring of 1989, I traveled to Boston in order to participate in the sesquicentennial celebration of Boston university. I gave one of my talks on the future to a large audience of BU students, speaking with my customary elan, and in the question-and-answer period, one of the students said, "We've been hearing some very good speeches, Dr. Asimov, and since you are on the BU faculty, why aren't you lecturing to us regularly?"

And I said, "Forty years ago I was placed on the faculty and I gave lectures for nine years, about a hundred of them altogether, and they were the best lectures the students ever had, but" - a short pause of about two seconds to make sure they were listening - "I was fired."

(Since Asimov had tenure, he could not be fired from the faculty ... but he stopped receiving his salary .. which did not bother him since he had income from his books).

10.1 Tax and regulate sugar like alcohol and tobacco  (2/2/2012)


Sugar should be regulated in the same way as alcohol and tobacco because its increasing use in processed foods poses a significant danger to public health, according to a group of scientists. They advocate controlling sales to children under 17 and taxing sugary foods.

.. For the first time in human history, long-term diseases such as heart disease, cancer and diabetes now pose a greater health burden worldwide than infectious diseases, according to the United Nations, contributing to 35m deaths annually. "There are now 30% more people who are obese than who are undernourished," said the UCSF scientists. "Economic development means that the populations of low- and middle-income countries are living longer, and therefore are more susceptible to non-communicable diseases; 80% of deaths attributable to them occur in these countries."

.. Dr Tim Lobstein, director of policy and programmes at the International Obesity Task Force, said sugar consumption was a major battleground for public health. "The large food manufacturers are very reluctant to see any restrictions on the use of cheap, bulk ingredients like sugars and starches. In the UK we have seen a gradual decline in sugar purchases, but this has been amply made up by an increase in sugar added to manufactured products, including ready meals, soups, snack foods and alcoholic drinks, and the last decade has seen record purchases of confectionery and soft drinks, despite endless health education campaigns.

... Sugar induces many of the diseases associated with "metabolic syndrome", including high blood pressure, diabetes and accelerated ageing. "It can also be argued that fructose exerts toxic effects on the liver that are similar to those of alcohol," said the UCSF scientists. "This is no surprise, because alcohol is derived from the fermentation of sugar."

.. One of the main reasons sugar has become such a problem is that it is impossible to avoid in modern society, argued the UCSF scientists. "Evolutionarily, sugar was available to our ancestors as fruit for only a few months a year (at harvest time), or as honey, which was guarded by bees. But in recent years, sugar has been added to nearly all processed foods, limiting consumer choice. Nature made sugar hard to get; man made it easy."

Can we justify the huge acreage devoted to the production of sugar in India? Will even one person die if sugar is not available?

10.2  Action needed to reduce health impact of harmful alcohol use  (7/2/2012)

A 2011 report by the World Health Organization states that 2.5 million deaths per year are caused by alcohol. "Almost 4% of all deaths worldwide," the report says, "are attributed to alcohol, greater than deaths caused by HIV/AIDS, violence or tuberculosis."

Health implications

Harmful use of alcohol has many implications on public health.
  • Nearly 4% of all deaths are related to alcohol. Most alcohol-related deaths are caused by alcohol result from injuries, cancer, cardiovascular diseases and liver cirrhosis.
  • Globally, 6.2% of all male deaths are related to alcohol, compared to 1.1% of female deaths. One-in-five men in the Russian Federation and neighbouring countries die due to alcohol-related causes.
  • Globally, 320 000 young people aged 15-29 years die annually, from alcohol-related causes, resulting in 9% of all deaths in that age group.
Too few countries use effective policy options to prevent death, disease and injury from alcohol use. From 1999, when WHO first began to report on alcohol policies, at least 34 countries have adopted some type of formal policies to reduce harmful use of alcohol. Restrictions on alcohol marketing and on drink–driving have increased, but there are no clear trends on most preventive measures. Many countries have weak alcohol policies and prevention programmes.

I got knocked off the road by a drunk a couple of years back - escaped with minor injuries. A passerby took down the registration number of the car and I was able to lodge a police complaint. The motorist was brought to book after about 3 months; he had also bumped into an auto rickshaw further down the road.

Turned out that he had lost Rs 30 lakhs in a business venture, so he decided to  get drunk and run amok. The motorist and an elderly gentleman who accompanied him (who seemed to know what to expect in such cases) were least concerned; not surprising, as the fine was only Rs 2000 (or Rs 2500), apparently the max that can be levied for such cases!

Driving under the influence of liquor is rife on Indian roads, if we wish to control it, the first step will be to increase the fine to some substantial fraction of a person's earnings.

10.3  The U.S. does not have a debt problem .. it has a health care cost problem  (10/2/2012)


That’s not my line, I took it from The Economist, but it’s a good one. If health care costs were under control, i.e. growing no faster than the economy, we could manage our debt. However, health care spending is growing at about 1.5x the rate of growth of GDP and is already close to 20% of the economy. In this post I will talk about the scary numbers. In the next post I will offer some thoughts on what we can do manage the situation.

If the trends of the last 20 years continue, health care spending will eat up U.S. GDP in our children’s lifetimes. See the first chart. The blue line is the federal government’s projection of health care spending. The red line projects spending at the trend growth rate of the last 20 years.

10.6 Ministry warns of new health care challenges  (8/4/2012)

While longevity has increased over the past years, the number of healthy years remains low, with an average of 12 years spent living with a disease during a lifetime. A person suffers an average of 2.6 diseases and only six percent of elderly people are healthy, Long said.
He said a survey by the Health Ministry found 95 percent of the elderly (60 years old and above) having chronic disease(s). They were also facing a double-danger as they were living at the time of a shift from infectious diseases to lifestyle-based diseases and chronic diseases.

10.7 The obesity epidemic  (5/5/2012) (7/5/12)


The similarities between the two public health challenges are compelling. Tobacco use is the nation's No. 1 cause of preventable death in the U.S., killing 467,000 people in 2005, according to a landmark study by Harvard University researchers. Being obese or overweight caused an estimated 216,000 deaths from heart disease, diabetes and other conditions, researchers estimated, while another 191,000 deaths resulted from being physically inactive — another key contributor to expanding waistlines.
..  In terms of health care costs, obesity is now the larger concern, accounting for $147 billion to $190 billion in yearly expenditures, compared with $96 billion for tobacco.

.. But there are many hurdles. The scope of the obesity problem is much larger than tobacco ever was: It touches on the food we eat, the beverages we drink, the amount of television we watch, how much we exercise, the way our cities are designed and more. While the variety of policy changes proposed are therefore broader, the political will to enact them has not materialized, in part because "people don't yet perceive a significant personal threat," said William Dietz, director of the division of nutrition, physical activity and obesity at the U.S. Centers for Disease Control and Prevention (CDC).

Beware. Your lifestyle can ruin your health

Of the 62 million Indians expected to have coronary heart disease by 2015, 23 million will be less than 40 years old. Currently, the prevalence of coronary heart disease in urban India is four times higher than in the US. “Roughly, one in two people, making it half of the city, suffers from at least one of these lifestyle diseases, if not more,” said Dr Aashish Contractor, head of the department of preventive cardiology and rehabilitation, Asian Heart Institute, Bandra-Kurla Complex.  “All these diseases are linked and increase the chances of heart disease and stroke. Exercise and a correct diet can help combat these diseases.”
Lifestyle diseases are not restricted to adults. A study conducted by the National Diabetes, Obesity and Cholesterol Foundation in 2009 revealed that one in every three children in private schools in cities such as Mumbai and New Delhi is obese. The study showed that since most junk food is targeted at children, they are high-risk cases for obesity.

10.9 Multimorbidity  (14/5/2012)


Over the past decade, multimorbidity—the existence of several chronic health disorders in one individual—has generated increasing interest. In an Article, Barnett and colleagues add to the evidence that patients with multimorbidity are the norm rather than the exception. Management of patients with several chronic diseases is now the most important task facing health services in developed countries, which presents a fundamental challenge to the single-disease focus that pervades medicine. The findings are discussed further in a Comment.
--
A radical health system overhaul is required so that the UK health system and those in other nations developed will be able to cope with the demand, as they were not designed to cater for these scenarios. 

One of the key challenges for governments and health-care systems all over the world is to manage the increasing amount of long-term disorders. 

At present, the main focus of the current healthcare system lies on individual diseases, delivery of health care and medical education, however, those with multimorbidities need a broader approach. It is burdensome and unsafe for patients having to use different services to manage several diseases in one person, as there is a risk of therapies being duplicated and inefficient due to poor coordination and integration.

10.11 Exercise doesn't help fight depression  (6/6/2012) 18


The study, carried out by teams from the Universities of Bristol, Exeter and the Peninsula College of Medicine and Dentistry, is the first large-scale, randomized controlled trial to analyse the effects of exercise on depression.

Earlier most of the evidence for the positive effect of physical activity in treating depression had originated from studies of small, non-clinical samples using interventions that would not be practicable in an NHS setting.



"Numerous studies have reported the positive effects of physical activity for people suffering from depression but our intervention was not an effective strategy for reducing symptoms", said Melanie Chalder, of the University of Bristol's School of Social and Community Medicine.

Hi Keith,

I was hoping that someone would comment on this research report. I had typed out my own reaction to the report; then decided to post the news in plain vanilla.
Queries I had typed out related to wondering how the patients exercised. Did they exercise using exercising machines? Did they go for walks early in the morning in a wooded park? Did they walk down a crowded place where they would bump into other human beings? So far as treating depression is concerned, I would expect the first method to be less effective!? It is quite possible however that this experiment was performed using exercising machines, so as to bring more 'control' to the scientific experiment. 

I agree with you that somatic ways of exercising would be the best. If the body is  kept well balanced, the whole body will get exercised with any activity. Without proper balance no system of exercise will reach all the muscle groups.

Regards,
Selvaraj




10.12 Mental health sufferers account for HALF of all illness  (18/6/2012)


'The under-treatment of people with crippling mental illness is the most glaring cause of health inequality in our country.'
One third of families have a member who is currently suffering from a mental illness, they say. It accounts for nearly half of absenteeism at work and mental illness accounts for nearly half of people on incapacity benefits.
The authors, who include doctors, psychologists, NHS managers and economists, condemn local health commissioners for inappropriately using allocated mental health funding and say that in some areas mental health provisions are being cut.
The authors also recommend better training of GPs and suggest that recruitment into psychiatry should be increased.
They also call for an “imperative” upgrade of specialist help to provide children with affective therapies, as there are 700,000 children in Britain with behavioural problems, anxiety or depression.

... 'Mental health is so central to the health of individuals and of society that it needs its own cabinet minister.'
The report concludes: 'Mentally ill people are particularly vulnerable.
'They are often afraid to seek help or even say they are unwell, and so are their relatives. But they represent nearly one half of all health-related suffering in this country.

10.15 Can Athletes Perform Well on a Vegan Diet?  (20/6/2012)


Q.. So is there any compelling reason for those of us who are active but not necessarily running ultramarathons to decide to become vegan?

A.. D. Enette Larson-Meyer: In general, vegetarians are healthier, with less risk for heart disease and obesity, although there are obese vegetarians. Many people tell me after they start a vegetarian diet that they feel better, but then again, many of them — and I believe this was the case with Scott Jurek — were eating a pretty poor diet before, so of course they feel better. They could have switched to a healthier meat-based diet and they would probably have felt better.
I like to tell people that if we got most Americans to eat one less serving of meat every day, there would be far greater impact from that, in terms of improving overall public health and the health of the planet, than convincing a tiny group of endurance athletes to go full vegan.

10.16 On the posture of perpetual girlishness  (29/6/2012)


 I t's not as if I were a cultural anthropologist or, even more unlikely, a sociologist. It's just that immersion in the American scene for eight decades has prepared me to spot some trends while also granting me the additional time to confirm them. In the present instance I've become painfully aware of a peculiar form of regressive behavior on the part of our womenfolk—or at least enough of them as to compel comment.
I refer here to the growing phenomenon of grown women sounding like prepubescent teenagers. This charge does not apply to the content of their utterances, but to their vocal timbre and speech pattern.
... Further social encouragement of adolescent behavior is found in the systematized veneration of youth and reciprocal disparagement of age. We are bombarded with images of men whose social and professional acceptability is imperiled by the graying of their hair, but who are able to revive their youth by the application of a hair-darkening elixir. The female rejection of aging is too ubiquitous to require examples. It is only necessary to note that this theme is sounded relentlessly throughout the media. To be young is to be desirable; to be judged otherwise is to be counted out of the game. Given all these factors, is it any wonder that we seize and hold on to the attributes of youth as long as possible? It is astonishing to discover the many ways by which natural maturation is systematically inhibited.

10.17 Lifestyle to blame for health care costs (28/7/2012)

Knee replacements are a good example. In recent years, on average, about a million knee replacements a year are performed worldwide. And although the U.S. only makes up about 5% of the world population, more than 50% of the knee replacements were performed here. In the U.S. the number of knee replacements is about 200 per 100,000 persons. The average for the European Union and Canada is a little more than 100 per 100,000 persons.
And I will give you one guess which country has more breast augmentations, liposuctions and nose jobs than the rest of the world combined.
Another challenge for the U.S. with respect to overall health care costs is our cultural approach to end of life care.

10.19 Chemicals in many antibacterial soaps linked with impaired muscle function (15/8/2012)

“We consider [triclosan] a high volume chemical,” Dr. Isaac Pessah, professor and chair of the Department of Molecular Biosciences in the UC Davis School of Veterinary Medicine, as well as the study’s lead author, told FoxNews.com.  “Its production levels are quite high, and the levels in humans have been increasing since it was first used as an antibacterial agent in the early ‘70s.  So the body levels in humans – including plasma, urine and breast milk – have been steadily increasing.”
“The levels in the environment have been increasing as well, because it can’t all be trapped in the treatment plants,” Pessah added about triclosan’s prevalence.  “[Companies] try to prevent some chemicals getting out past the water treatment plants so they can dispose of them in a different way, but they can’t capture all of [triclosan] because there is so much of it.”
... “When people ask me about this, I say that we’ve been taking great care to buy products without triclosan,” Pessah said.  “Instead, buy disinfectant hand wash based in alcohol.  There’s no literature that says it’s more useful than just soap and water. The risks definitely outweigh the benefits.”

Despite an injection of more than $240 billion in government funding into health care over the past three years, the doctor-patient relationship has continued to break down. Doctors are overworked and underpaid, and many push drug sales or charge extra for services such as deliveries to make more money. Patients are faced with high medical expenses, brief consultations and often poor quality care.

... The anger built up over years is now exploding into violence, with doctors, nurses and interns around the country stabbed, punched or otherwise assaulted by patients or their relatives over the past year.

Top 10 Foods Highest in Vitamin B12
Read more at http://www.healthaliciousness.com/articles/foods-high-in-vitamin-B12.php#Skx9C5E85WjBLupb.99
Vitamin B12 is needed for cell division and blood formation. Neither plants nor animals make vitamin B12. Bacteria are responsible for producing vitamin B12. Animals get their vitamin B12 from eating foods contaminated with vitamin B12 and then the animal becomes a source of vitamin B12. Plant foods do not contain vitamin B12 except when they are contaminated by microorganisms or have vitamin B12 added to them. Thus, vegans need to look to fortified foods or supplements to get vitamin B12 in their diet. Although recommendations for vitamin B12 are very small, a vitamin B12 deficiency is a very serious problem leading ultimately to anemia and irreversible nerve damage. Prudent vegans will include sources of vitamin B12 in their diets. Vitamin B12 is especially important in pregnancy and lactation and for infants and children.
http://www.vrg.org/nutrition/b12.htm

... One of the most common overlooked diagnoses for impairment of Proprioception that effects a person's walking, especially in people over 60, is Vitamin B12 deficiency. If a Vitamin B12 deficiency is left untreated it can result in permanent damage to nerves in the upper spinal cord called Subacute combined degeneration of the spinal cord, resulting in the nerves from the feet not communicating properly with the cerebellum.
http://en.wikipedia.org/wiki/Proprioception

.....................

In the list referred to, the top eight food items are Non Veg.
The bottom two are Veg: Cheese and Eggs (if egg can be considered to be veg)

You would have to eat 180 gms of Swiss Cheese to obtain your daily requirements.
(Swiss cheese provides the most with 3.34μg (56% DV) per 100g serving)


You would have to eat 17 eggs to get your daily requirements!
(When it comes to chicken eggs the raw yellow has most of the vitamin B-12 with 1.95μg per 100g serving (33%), however, this equates to 0.33μg per yolk or just 6% of the DV. The eggs of other animals are higher with a goose egg providing 7.34μg (122% DV) of vitamin B-12 per 100g serving, and a duck egg providing 3.78μg (63% DV) )

Milk and milk products contain B12, but you would have to consume sufficient amount of it:

Yogurt (No Fat) : You would need to consume 1 lit
Yogurt (Whole) : 1.7 lit
Skim Milk : 1.1 lit
Whole Milk : 1.5 lit
Low fat Buttermilk : 2.5 lit

In states such as Punjab and Haryana where farming communities consume large amounts of milk, there should be no problems with a veg diet; elsewhere there could be problems. Would providing supplements be the only way out of this problem? Are children's midday meal schemes taking care of this issue? Apparently a person having NV diet can store 20 years supply in his body. It is possible to check the level of B12 in a person's body; should children in India be tested for B12 deficiency?

.. Moreover, they don’t make anyone any money in advocating for them.

Ignore those messages. Losing weight, keeping away from cigarettes and staying fit are the proven ways to reduce risk.


The benefit of the treatment, known as chelation therapy, barely reached statistical significance, and there were questions about the reliability of the study. Even the investigators in the trial said the results were insufficient by themselves to justify recommending use of the treatment.
Still, the unexpected finding should provide some vindication to the National Institutes of Health for sponsoring the $30 million study, which was plagued by delays and problems.

''Every five years or so something is done about mental health and then it gets forgotten, but the government now needs to actually implement their policies,'' Professor Fels said.
"The statistics related to physical illness and early death among people with a mental health difficulty are appalling.

''People with a severe mental illness have their life expectancy reduced by 25 years on average due to the increased likelihood of heart-related conditions, diabetes and obesity.''
