Mathematics mayhem – paper proving the impossible to be possible retracted for lack of “scientific content”

April 17, 2012

This is hilarious but it does make the Dr.Mahalingam College of Engineering & Technology, Pollachi, Tamil Nadu look ridiculous.  This paper was accepted for publication by Elsevier and has now been retracted by the publishers for not containing any scientific content. It seems that the authors have applied a computer program to a “problematic problem” and have proved a 4 300 year old “impossible proposition to be possible” !

“Computer application in mathematics” [Comput. Math. Appl. 59 (1) (2009) 296–297], by M. Sivasubramanian and S. Kalimuthu, Department of Mathematics, Dr. Mahalingam College of Engineering and Technology, Pollachi, Tamilnadu-642003, India

The paper is here : Sivasubramanian and Kalimuthu

But while the paper itself is remarkably short and is just a nonsense paper, it does not say very much for Elsevier’s editorial acumen or for its peer-review process. Perhaps this journal should be retracted for lack of editorial content? Timothy Gowers will surely get more support for his Elsevier boycott in the UK.

Settled science? Karakoram glaciers, polar bear and emperor penguin numbers are all growing – not disappearing

April 16, 2012

A settled science? Global warming was going to melt all the Himalayan glaciers by 2035, polar bears were going to be exterminated and emperor penguins populations were going to be devastated. But the climate models are proving to be just the wishful thinking of an alarmist creed.

1. The Guardian: The glaciers flowing between the towering peaks of the Karakoram range on the Pakistan-China border have grown in size in the last decade, according to new research. The impact of climate change on the ice in the greater Himalaya range has been controversial because of an unfounded claim by the United Nations’ climate science panel over the rate of melting in the region. However the melting of vast volumes of ice into the sea in most other parts of the world has been clearly demonstrated. In March, scientists showed that far less ice was being lost across the Himalayas than had been estimated from sparse ground surveys on the remote slopes.

The new study shows that glaciers in one important part of the mountain range are growing. “We provide a detailed glacier-scale evaluation of mass changes in the central Karakoram,” said Julie Gardelle, at CNRS-Université Grenoble, who led the research published in Nature Geoscience on Sunday. …

2. Polar bear populations have never been as large as they are now.

3. Emperor penguin populations are twice the size they were once thought to be.

It is time for the climate brigade and their hangers-on to develop a little humility and acknowledge that the chaotic, turbulent layer around the earth which creates our climate is far from being understood.

Time to ditch some of the models.

Professor at IIM-A resigns

April 14, 2012

Update 2014! See new post 

Update!

There are many comments in support of Prof. Dass  and some in support of Sujoy Pal. But many are rather nasty and merely personal attacks against the one or the other. I have left the last comment with one of Prof. Dass’ students which is rather more compelling than the personal attacks.

But if the allegations against Prof. Dass are largely malicious then it is a great pity that

  1. he resigned, and
  2. that IIM-A has not backed him up and declined to accept his resignation.

IIM-A does not come out of this very well. My tentative conclusion to all this is that IIM-A is still developing its own internal processes and does not really know – yet –  how to handle matters of alleged plagiarism.

There are some parallels with development of internal processes in industry to deal with corruption over the last 15-20 years. Here the mistake made by industry – in my opinion – was to focus on compliance rather than on ethics. A focus therefore on detection and punishment rather than on prevention. There is a risk that Indian Universities are going down the same path with a focus on plagiarism detection rather than on ethics. While the act of “policing” cannot be avoided by organisations the mere mechanical use of software to detect plagiarism is not enough. My own experience is that if ethics can be sound then compliance (or plagiarism) largely become non-issues. The challenge is  how to institutionalise the development of sound ethics in any organisation.

Comments on this subject are now closed.

=============================

Professor Rajanish Dass at the Indian Institute of Management in Ahmedabad had blamed his co-author, Sujoy Pal (a research associate) for the plagiarism he was found guilty of. Dass has claimed that it was due to “ignorance and not intention” and had taken his case to the Gujarat High Court which had given him a small measure of relief when it had instructed the Institute to take some of his additional responses into account.

But he has now bowed to the inevitable and resigned.

Faculty of Indian Institute of Management, Ahmedabad (IIM-A), Rajanish Dass, who had approached the high court after the institute accused him of plagiarism, has chosen to resign from his post at the institute. 

Confirming the resignation, dean of academic affairs at IIM-A, B H Jajoo said, “He left on April 2.”  ……. In its report to IIM-A director Samir Barua on February 3, the committee concluded that allegations against Dass were “valid” and he has resorted to plagiarism in three papers. Confirming his resignation, Dass said, “I submitted my resignation due to health issues on April 2, which was accepted by IIM-A on the same day.” 

Dass has been on medical leave from the institute since the time he had approached HC (the High Court).

Considering that he had resigned 12 days ago and in a rather high profile case, it is a little surprising that the Institute did not have the courage to come out with the news of his resignation immediately. It suggests that they have not yet seen the advantages of transparency and that some are perhaps still hoping that the plagiarism issues cropping up at IIM-A will merely go away.

Some students at IIM-A have also accused Dass  – anonymously – of having outsourced his own thesis to students at Jadavpur University.

Another dent in anti-nuclear paranoia as wildlife thrives after Chernobyl

April 13, 2012

Even with the advent of shale gas, the capital cost of nuclear power plants means that they remain the most economic, viable and safe option for large-scale, base-load power generation for the foreseeable future. And part of the unnecessary time (and cost) associated with building nuclear power plants is primarily due to the obstructionist and delaying tactics of the alarmist lobbies.

A new research paper finds that some of the alarmist scenarios after the Chernobyl accident have been grossly exaggerated. In all likelihood the same strident alarmism evident after Fukushima is also highly exaggerated.

What makes a “good” manager?

April 12, 2012

Much of my work these days is in helping organisations in the selection of their managers. This has developed into a series of  talks and “workshops” for those involved – or to be involved – in the selection and recruitment or promotion of managers.

The objective is of course to appoint managers who will be successful (however success is to be defined). But that “success” lies in the future and will only ever be measured in retrospect. While defining what would constitute “success” is vital, it is my contention that the selection process has to focus on the “goodness” of the manager.

I take “goodness” to be an inherent attribute of a manager whereas “success” is a value-judgement of what has been achieved – but only and always in retrospect. “Successful” cannot and should not therefore be equated with or substituted for “good”.

Success is transient. Just like profit or cash-flow – it is over once it has been recognised. The success counter is set to zero once the success is “booked”.  Goodness lasts longer – it is like a balance sheet item. This financial analogy is sound. A success once booked – like profit or cash – gets transferred to the goodness in the balance sheet. It is available as a balance sheet item for future results but does not – in itself – ensure such future results. Past successes like previous profits provide a track record and an indication of things to come but do not, in themselves, ensure future success or profit. And just as a lack of profit or a shortage of cash can impair a balance sheet, a lack of success can impair a manager’s goodness.

Success and goodness are different.

The likelihood of a manager with a proven track record of success being a “good” manager is high. There is also no doubt that the probability of a “good” manager achieving the best result possible is high. From this it follows that the chance of achieving success is enhanced with a “good” manager. Success though does not just require goodness. And goodness does not ensure success. But goodness does predicate achieving the best result possible. In other words, if the goodness is inherent then the track record may follow. To continue with the financial analogy, if the balance sheet is sound then the probability that profits and cash may follow is enhanced.

Therefore it seems to me to be a much more grounded approach to focus on the goodness of a prospective manager rather than on just his track record of past successes or on trying to make a forecast of his future success.

I define nine fundamental “building blocks” which together as a package indicate the potential “goodness” of a prospective manager: Read the rest of this entry »

8.7 magnitude earthquake off Aceh again – tsunami watch

April 11, 2012

Update: A small tsunami (17cm) is reported to be heading towards the Aceh coast but the US Geological Survey believes the risk for a large tsunami is small. A tsunami “warning” is in effect in Sri Lanka and the eastern coast of India. Tremors were felt 1500km away across Southern India; in Chennai, Bangalore and Thiruvananthapuram among many other cities.

Breaking!

Indonesia issued a tsunami warning Wednesday after an earthquake with a preliminary magnitude of 8.7 hit waters off westernmost Aceh province. tremors were felt in Singapore, Thailand, Malaysia and India. High-rise apartments and offices on Malaysia’s west coast shook for at least a minute.

The Pacific Tsunami Warning Center in Hawaii said a tsunami watch was in effect for Indonesia, India, Sri Lanka, Australia, Myanmar, Thailand, the Maldives and other Indian Ocean islands, Malaysia, Pakistan, Somalia, Oman, Iran, Bangladesh, Kenya, South Africa and Singapore. …

A giant 9.1-magnitude quake off the country on Dec. 26, 2004, triggered a tsunami in the Indian Ocean that killed 230,000 people, nearly three quarter of them in Aceh.

Interestingly the Piers Corbyn’s March forecast for extreme weather (based on solar activity) had identified 8th – 10th April as being especially prone to severe earthquake or volcanic activity.

China downgrades solar and wind power – pushes for nuclear, hydro and shale gas

April 8, 2012

Common sense and simple economics are beginning to reassert themselves as the the fundamental weaknesses in the fashionable – but subsidised – expansion of solar and wind power plants are revealed. The expensive, intermittent and unpredictable generation  that derives from solar and wind power plants can – at best – be used to augment an existing system. They are actually useful as an auxiliary heat and power source as small decentralised units. But in a large power grid they are more of a nuisance than an asset and can only increase the cost to the consumer.

China has now published a policy document changing direction towards nuclear and hydro power and an accelerated development of shale gas use. Solar and wind power are downgraded.

Electric Light & Power

China will accelerate the use of new-energy sources such as nuclear energy and put an end to blind expansion in industries such as solar energy and wind power in 2012, Chinese Premier Wen Jiabao says in a government report published on March 5.

Polargate investigation questions new witnesses

April 6, 2012

The Polargate investigation being conducted by the Department of the Interior’s Office of Inspector General “is looking into allegations of scientific misconduct related to a 2006 report by wildlife researchers Charles Monnett and Jeffrey Gleason, who described seeing dead polar bears floating in Arctic waters. The apparently drowned bears raised concerns about the effect of melting ice in the Arctic, and they were mentioned in Al Gore’s movie An Inconvenient Truth.”

Now NPR reports that new witnesses are being questioned in this 3 year old investigation:

Polar bear numbers in Canada “likely the highest there has ever been”

April 6, 2012

Polar bears near Churchill, Manitoba: Ward Kennan photolibrary

DNA studies have shown that polar bears and brown bears have a common ancestry. The genetic split occurred about 150,000 years ago in the late Pleistocene just before the end of the Pleistocene glaciation known as the Ice Age. They evolved to meet the conditions of the Ice Age and they continue to adapt. In their present form as polar bears they have survived previous interglacials with temperatures greater than we have at present. And far from being endangered and under threat of extinction they continue to adapt their behaviour and to prosper.

New surveys have shown that

India, Italy to cut renewable energy subsidies

April 4, 2012

Subsidies for renewable energy only distort the market and are counter-productive. The game in renewable energy (wind and solar) has become the extraction of subsidies rather than the production of electricity. The sooner they are dismantled the better.

Two developments in Italy (which is virtually bankrupt) and in India (where growth is slowing) – both driven by economic considerations – are indicators that that some of the artificial gloss around renewable energy may be peeling off. Exorbitant feed-in tariffs for renewable energy are to be curtailed in Italy while very attractive tax-breaks for wind-power in India are to be reduced.

Italy to cut renewable energy subsidies

Italy will move to reduce taxpayer subsidies to its renewable energy sector after last year’s boom in solar power, Industry Minister Corrado Passera says. The official said Saturday in Cernobbio, Italy, that taxpayer subsidies doled out to the wind and solar power industries had generated “excessive” investments in the sector, The Wall Street Journal reported. “Italy has important goals to meet and even surpass,” he said, but added, “we need to do so without over-reliance on taxpayer resources.”

The government, Passera said, will in the coming years “realign” the level of its incentives to those of other European countries. ….

The Hindu Business Line reports on the new budget measures in India. Windmill developers to lose tax breaks

Windmill developers will no longer enjoy lower tax outgo in the first year, for investing in windmills.

Effective April 1, accelerated depreciation – which allows the investing company to fast track the write-off of certain assets for tax purposes – will not be allowed to wind energy developers. The Income Tax department has amended the rules regarding this, through a notification.

Until FY-12, a deduction of up to 80 per cent was allowed if the wind project was commissioned before September of a fiscal. Projects commissioned in the next half of the fiscal got a 40 per cent deduction. Now developers will only be allowed 15 per cent depreciation.

But wind equipments will still enjoy the 20 per cent additional depreciation prescribed for power equipments in the recent Budget. That would make for an effective 35 per cent depreciation. …….
