Nalband mutation

In The Hindu Interpretation of a malady: how scientists zeroed on one family's rare and crippling disease
From the summary of an earlier research by Suvrat Kher"3) The findings indicate that there is a larger amount of genetic variation between Indian groups than there is between say European groups. This the authors suggest is a result of a small number of individuals founding different ethnic groups that then remained endogamous and therefore genetically divergent. This has important medical value as recessive diseases may correlate with ethnic groups."

Two for April

It is spring in the northern hemisphere. A post by Ramarao Kanneganti brings back these lines:

"APRIL is the cruellest month, ....,,
 
mixing 
Memory and desire, "
 And from Mahe Jabeen for any season
"అతనెప్పుడూ అంతే
ఒంటరిగా రమ్మంటే వసంతాన్ని వెంట తెస్తాడు"
Which roughly translates "He is always like this.
I keep asking him to come alone but he brings spring along"

The second poem with translation here


Rules of memory

Beautifully rewritten "The US and Japanese team found that the brain "doubles up" by simultaneously making two memories of events. 
One is for the here-and-now and the other for a lifetime, they found.
It had been thought that all memories start as a short-term memory and are then slowly converted into a long-term one.
Experts said the findings were surprising, but also beautiful and convincing."

Rohan Pavuluri

Forbes on his venture Upsolve "It sounds like a contradiction in terms: Millions of Americans may be too broke to go bankrupt. But with studies showing that more than half of U.S. households can’t come up with $1,000 in cash in an emergency and a third have no savings at all, it shouldn't be surprising that the $1,300 cost of filing for Chapter 7 bankruptcy is a hurdle many debt-ridden consumers can’t get over.
That dilemma struck a Harvard sophomore named Rohan Pavuluri as odd – and a potential opportunity. He turned his curiosity into a nonprofit, Upsolve.org, that has pulled in more than $70,000 in funding and support from universities and the hedge-fund-sponsored Robin Hood Foundation. Upsolve’s mission is to try and help poor people avail themselves of bankruptcy, what Pavuluri – himself the prep-school educated son of two physicians – describes as “one of the best parts of American capitalism.”"

Steve Keen interviews Michael Hudson

Fixing the economy sort of jump,ed. parts understandable and generally interesting. Sample:
"Now think of the circular flow. The whole of economics was founded by a doctor, Francois Quesnay in France that looked at a national income like the circulation of blood in the body. But you have this blood being drained - 75% of the circular flow now is drained for what we call the FIRE sector - finance, insurance, and real estate."
And stuff like this:
"Peshine Smith was the law partner of William Seward, who everybody had expected to be the presidential candidate. But by being so outspoken against slavery, they decided to get a gray figure. Someone nobody had ever heard of that was - they hoped would be completely mediocre. Abraham Lincoln.
Are you kidding?
He made William Seward secretary of state, and after Seward resigned, he made a trip around the world and went to Japan. And they said, we want to break away from England’s free trade policy. So he sent Peshine Smith over to be an advisor to the Mikado, who they waited till the British ambassador went on vacation, passed protective tariffs. And Smith went native and had a Japanese mistress and wore a sword when he went out in a kimono and everything and introduced protective industrial policy to Japan.
Which is what turned it from being a rural colony of totally feudal in 1868 through to an industrial super power that could challenge the Germans and the Russians in the First World War."

Trump intervenes in Syria

Nobody seems to know why. Longtime observer of the Middle East, Juan Cole seems to think that Assad might have been responsible for gas attack since his army is depleted and weary. He does not spare either side but I do not know how neutral he is. Here are two posts by him:
The Latest
And Slightly earlier.
In the earlier post, though he does not give any evidence to show that the Syrian government is responsible, he says "Some Syrian military units have a chem team in case they face being overwhelmed by a more numerous enemy. The Syrian army was 300,000 before the war. It is at most 50,000 now. That number is not sufficient to control the whole country, though with the help of the Lebanese Hizbullah and Iraqi militias and some Afghans dragooned by the Iranian Revolutionary Guards Corps, plus vigorous Russian air support, they have been able to fight off the rebels and to take most urban areas. The small number of troops means that when they fight in a rebel-held territory like Idlib Province, they are tempted to deploy chemical weapons to offset their small numbers."
With he propaganda by the governments being what it is, we may never know, as in the MH 17 case.

Squid and octopus can edit and direct their own brain genes

https://www.newscientist.com/article/2127103-squid-and-octopus-can-edit-and-direct-their-own-brain-genes/
"Unlike other animals, cephalopods – the family that includes octopuses, squid and cuttlefish – do not obey the commands of their DNA to the letter.
Instead, they sometimes interfere with the code as it is being carried by a molecular “messenger”. This has the effect of diversifying the proteins their cells can produce, leading to some interesting variations.
.....
The mechanics of cephalopod RNA editing are still being investigated.
“When do they turn it on, and under what environmental influences? It could be something as simple as temperature changes or as complicated as experience, a form of memory,” says Joshua Rosenthal, lead author from the Marine Biological Laboratory at Woods Hole, US."

Community Resource Persons

Community resource persons are torchbearers of a resurgent countryside
"Over the years, civil society organizations have been struggling with the uncomfortable question of how to reach a large number of citizens in many locations? It is rather a disturbing question since many of the NGOs engage with village communities as a so-called outsider. The NGO professionals come, interact with the village community, work with them but when the deadline of the project is over, most have no option but to wind up their operations or wait for another project to begin. Very few continue to engage with the community in the same area with their own resources.
More than the phasing out of the projects, the fundamental question has been about the community taking charge of its own developmental processes and ownership what in academics is known as agency. Do communities continuously remain in the mode of recipients or is there a way out when they become not just initiators of their developmental agenda but also become torchbearers for other communities outside the geographical boundaries that they belong." 
There are many more like VRHP, NRHM,... I do not know whether there is a list somewhere of such organizations and their work.

Quantum physicist attack the Riemann hypothesis

A Quanta article by  Natalie Wolchover
"As mathematicians have attacked the hypothesis from every angle, the problem has also migrated to physics. Since the 1940s, intriguing hints have arisen of a connection between the zeros of the zeta function and quantum mechanics. For instance, researchers found that the spacing of the zeros exhibits the same statistical pattern as the spectra of atomic energy levels."

With the Syrian Army and its allies in a comfortable position in Syria, making advances across the country, and recovering lost points in rural Hama, why would they now resort to using chemical weapons in Nusra Front occupied Idlib? It is a very simple question with no clear answer. It defies any logic that on the eve of a Syria conference in Brussels and a week before peace negotiations are to resume, that the Syrian government would blatantly use the non-existent stock of chemical weapons."

Human trafficking in India

from the Logical Indian blog some excerpts:
"Close to 80% of the human trafficking across the world is done for sexual exploitation and the rest is for bonded labour and India is considered as the hub of this crime in Asia."
"According to an article in Firstpost, Delhi is the hub of human trafficking trade in India and half of the world’s slaves in India. Delhi is the hotspot for illegal trade of young girls for domestic labour, forced marriage, begging and prostitution. Delhi is also the transit point for human trafficking."

Reasons:

"Fundamental theory of demand and supply is applicable to this situation as well. Men for work generally migrate to major commercial cities and from here the demand for commercial sex is created. To fulfill the supply all sorts of efforts are made by the suppliers like abduction etc. Young girls and women belonging to poor families are at higher risk.
Then comes the economic injustice and poverty. If you are born to a poor family in India then you are at a higher risk of being sold. If you are born to a poor family and a girl then these chances further increases. Sometimes parents are also desperate to sell their daughters to earn money.
Social inequality, regional gender preference, imbalance and corruption are the other leading causes of human trafficking in India."
And "Haryana, with the country’s worst sex ratio of 879 girls to 1,000 boys, now has to increasingly import brides from poverty-stricken states such as Assam, West Bengal, Jharkhand and Orissa. It’s the same story in Punjab and Uttar Pradesh where female foeticide is high and the sex ratio skewed. According to the 2013 National Crime Records Bureau (NCRB) report, 24,749 children and women between the ages of 15 and 30 were kidnapped and sold into marriage across the country."

Joan Feynman

From Auroras to anthropology “Women can’t do science, because their brains aren’t made for it,” Lucille Feynman declared to her eight-year-old daughter Joan. The news was a huge blow to the little girl’s ambitions which, at the time in 1935, were firmly set on following her brother Richard into a life scientific. “I remember sitting in a chair and weeping,” she recalls.
"The path of Joan’s life would be changed significantly one night when Richard woke her up and told her to get dressed and follow him out into the street. He took her away from the house and the street lights and out onto a wide open golf course nearby with a big dark sky above them. “I can still remember in my mind’s eye the green lights dancing in the sky”, Joan recalls of the flickering northern lights Richard had lead her outside to witness. “He told me that it was an aurora and no one knew what caused it exactly.”
In that moment, she was hooked. And whilst the doubts about a woman’s abilities to undertake a career in science, planted in her by Lucille, remained, Joan’s interest in science continued to be fuelled by Richard’s progress through university. Before he’d left home, her brother had made a deal with her that whilst away at the Massachusetts Institute of Technology (MIT), studying for his bachelor’s degree, he would answer any science question that she sent him."

A retiree solves a mathematical problem from 1972

 A retiree discovers an elusive proof- and nobody notices
"AS HE WAS brushing his teeth on the morning of July 17, 2014, Thomas Royen, a little-known retired German statistician, suddenly lit upon the proof of a famous conjecture at the intersection of geometry, probability theory, and statistics that had eluded top experts for decades.....
Proofs of obscure provenance are sometimes overlooked at first, but usually not for long: A major paper like Royen’s would normally get submitted and published somewhere like the Annals of Statistics, experts said, and then everybody would hear about it. But Royen, not having a career to advance, chose to skip the slow and often demanding peer-review process typical of top journals. He opted instead for quick publication in the Far East Journal of Theoretical Statistics, a periodical based in Allahabad, India, that was largely unknown to experts and which, on its website, rather suspiciously listed Royen as an editor. (He had agreed to join the editorial board the year before.)
With this red flag emblazoned on it, the proof continued to be ignored. Finally, in December 2015, the Polish mathematician Rafał Latała and his student Dariusz Matlak put out a paper advertising Royen’s proof, reorganizing it in a way some people found easier to follow. Word is now getting around. Tilmann Gneiting, a statistician at the Heidelberg Institute for Theoretical Studies, just 65 miles from Bingen, said he was shocked to learn in July 2016, two years after the fact, that the GCI had been proved. The statistician Alan Izenman, of Temple University in Philadelphia, still hadn’t heard about the proof when asked for comment last month."

The feudal republic of India

An article from The Outlook by Pranayama Sharma. Though the article appeared on April 1, much of it rings true "Freedom from colonialism was meant to be a harbinger of a real freedom at all levels, an abolition of the old order built around entitlements and privilege. And yet, all around us is a scenario brimming with those signs and elements of power. A new feudal order is upon us, in a variety of forms. The political class may exemplify it, but its grandees are no sole copyright holders. Everyone wants a piece. All institutions, all spaces, all realms of life are marked by an unholy scrimmage. And it’s produced a new breed that has swamped the landscape: the Ugly Indian."

Raghavan Narasimhan 1937-2015

I just learnt that one of my teachers in 1964 Raghavan Narasimhan passed away in 2015.
His obituary
My recollections:
His course in 1964  was excellent. We learnt in six months what would have probably taken a couple of years. When he was a college student, he translated several monographs and kept those written translations. I learnt some topology from his translation of Alexanderoff and Hopf. But I never got along well with him. He learnt too much mathematics when he was young which might have tempered his creative juices and it seemed to me his creative achievements were not compatible with his talents. Moreover, he suffered from insomnia. Once in a while, there were pretensions of understanding some stuff without really knowing it and it was not difficult to bullshit him. There seemed to be an undercurrent of trying to impress westerners and his estimate of other Indians seemed depend on how well they were impressing the other westerners mathematically. He wanted chelas around as he was a bachelor for a long time and he tried to carry it on in Zurich too but after a while settled down. I met him a few times in Chicago in Pavaman Murthy's house. Last time I was there, may be around 2007, Pavaman wanted to invite him for dinner but I did not want to see him. So, I missed my last opportunity to see him though he could be often helpful. In the 1980s, he offered to translate a German paper for me. A complicated man, a good man in many ways but not my cup of tea since I did not like to be pushed around.

Yevgeny Yevtushenko RIP

The name has been familiar but I do not remember reading him. Going through the recent write ups about him, I found this little excerpt from 'Zima Junction'
"I had no doubts about harmonious answers
which could and would be given
to every question.
But suddenly, this felt necessity
of answering these questions for myself.
So I shall go where I started from,
sudden complexity, self generated,
disturbed by which I started on this journey.
Into my native forest among those
long-troden roads I took this complication
to take stock of that old simplicity,
- like bride and groom, a country matchmaking."

Sunita Narain discusses meat consumption in India

Why I don't advocate vegetarianism "But the most important reason I, as an Indian environmentalist, would not support action against meat is that livestock is the most important economic security of farmers in our world. Indian farmers practice agro-silvo-pastoralism, that is, they use the land for crops and trees as well as for livestock. This is their real insurance system, not the banks. Livestock is also not kept by large meat businesses but by big, small, marginal and landless farmers. It works because the animals have a productive purpose: first, they give milk and manure and then, meat and leather. Take that away and you will take away the base of economic security of millions in the country, greatly impoverishing them." and more. Worth a read or two.

From The Age. One of those, may be there is some thing in it. The last bit:

And of course, it will keep us young.
"There are substantial basic science data to support the idea that exercise is critically important to prevent or delay ageing," says Nair, who plans to look at the effect of exercise on other tissues in the body. "There's no substitute for that."

While it is undeniable that there are fundamental problems like poor quality of health care, which need systemic reforms that go beyond a single program, the NRHM has helped achieve significant improvements in a broad spectrum of health outcomes - maternal and child mortality - and outputs - immunisation, ante-natal care, institutional deliveries etc. 

The most striking indicator is the near doubling of institutional deliveries over a ten year period."

why human males are bigger than females ?

Human males are bigger than females because.... by Ryan Gregory. The answer seems to be we do not really know. "In humans, males tend on average to be larger, to mature later, and to age and die sooner than females. It’s easy to assume, as many people do, that this difference between males and females — what biologists call sexual dimorphism — is the result of sexual selection. That is, males are larger because they fight each other over access to females and/or females prefer to mate with larger males. That is a valid hypothesis, of course — but too often it is simply accepted as fact and then used as a starting point for discussing other male and female traits. As a recent example, consider the debate that is happening on the blogosphere about sexual dimorphism in humans, and whether objections to the standard explanation of fightin’ males is merely political." For the terms used check http://evolution.berkeley.edu/evolibrary/article/evo_02 and another view of the Clyne-Dunsworth debate see also How do we know what we know? Sexual selection, in humans and in lizards by Ambika Klamath.

Small victories all around, but still the Indians prevail by Greg Baum
"The sum of all these victories, great and small, was a series for the ages, a titanic contest, maybe the most gripping Australia have played in since England 2005 (also a 2-1 defeat), and not even a little passing pettiness could diminish it.
Australia surpassed themselves, India surpassed Australia. Here's a look through one dimension: Smith made 499 runs and Cheteshwar Pujara made 405 runs, and KL Rahul made 50 in every innings bar one, and R Ashwin took 21 wickets, and Nathan Lyon and Steve O'Keefe 19 each, and none of them were man of the series because Ravindra Jadeja took 25 wickets and made vital half-centuries at two telling passes, and so he was, and who could argue?"

Discussions on education

Lots of discussions about education from first principles these days like this one from my friend the admirable Rahul Banerjee Exorcising the maths demon and also on his wall.
About university education, Owen Dixon, a justice in the Australian Supreme Court reminded in 1954 that a university's responsibility remained unchanged: to produce people whose " minds have become better instruments of thought, whose intellectual interests have been stimulated and will often be sustained, and above all who can combine knowledge with reason and both with experience so as to meet the problems of real life."
To some extent, the purposes of school education are similar with the proviso that vocational education also takes place for those who do not want to or cannot go to universities. We do not know what will be needed in future and generally try to ground the students in an all round education which not only teaches facts but also develops habits of thought. For example, we may never use the Euclidean geometry which we learn around ninth grade, but ideas of proof, logical arguments are imbibed at an age where we do not really understand the purpose of such things. It is also difficult to understand every thing that may be need in future but at a young age people absorb like sponges and remember things some of which become clearer later on if one pursues. In my opinion, very few understand calculus in their first attempts, but can acquire some feel and can use it mechanically after a while. And most things we use these days involve calculus, linear algebra and such at various stages. So, one purpose to get these through as much as possible st a young age even if only a fraction use them later on and for most the overall curriculum develops some useful knowledge and habits of thought.  These requirements get larger with time and an average high school graduate now probably knows more than an average teacher a couple of centuries ago. These are achieved through processes of synthesis and pruning. That is for the good part. There are also dubious aims like control, hold children in prison like conditions when their hormones or raging, get them to confirm and become useful tools in the enterprises that the current powers deem necessary. As Foucault wryly asks: ‘Is it surprising that prisons resemble factories, schools, barracks, hospitals, which all resemble prisons?’ If Foucault is right, we are subject to the power of correct training whenever we are tied to our school desks, our positions on the assembly line or, perhaps most of all in our time, our meticulously curated cubicles and open-plan offices so popular as working spaces today.'

Generally, there is a disjunct between what we use and what we understand about what we use. All this does not mean laymen like us should not discuss education. Like many other things, there are big chains in every thing and those who try to explain or question existing state of things should study a bit more about these chains and try to explain the consequences of cutting calculus or some other subject from the syllabus and its implications to different groups. Governments are keen about quick successes and appoint various panels to suggest changes and in India often the tendency is to catch up with western success and copy some of their recommendations which may sometimes be influenced by vested interests. For example, this happened with the BT Brinjal recommendations by a government panel. I have some experience with panels as I was once part of a panel to recommend undergraduate syllabus for the whole of India. Since my experience at that time was in reasearch and not teaching, I quietly slipped away from the task. In any case, these syllabi depend on what the governments decide to do at a given time, not arbitrarily but with in some parameters,  and formulated by experts in another chain of expertise parts of which may be dubious. As in the BTBrinjal case ( where the first expert report was a copy of a US government report that was favourable to big business), constance vigilance by NGOs and noise may help to reduce the unsuitability. So I welcome Rahul Banerjee's discussion but on his wall, at the moment it seems to be all over the place. So, my suggestion would be to ask for outside representation in these panels, namely from users interested in teaching and perhaps with some experience in teaching. There are several such NGOs in India.

A readable article on Foucault

Simon Critchley went to talk to his philosophy teacher Frank Cioffi:"Some years later, I went back into his office to ask permission to switch from one course to another. “Which courses?” he said indifferently. “I’m meant to be reading Foucault, but I want to do a course on Derrida.” “Man” he replied “that’s like going from horseshit to bullshit.” "
But there seems to be some thing in the horseshit as this article observes The power thinker
Some quotes:
Foucault wryly asks: ‘Is it surprising that prisons resemble factories, schools, barracks, hospitals, which all resemble prisons?’ If Foucault is right, we are subject to the power of correct training whenever we are tied to our school desks, our positions on the assembly line or, perhaps most of all in our time, our meticulously curated cubicles and open-plan offices so popular as working spaces today.
Another:
For identifying and so deftly analysing the mechanisms of modern power, while refusing to develop it into a singular and unified theory of power’s essence, Foucault remains philosophically important. The strident philosophical skepticism in which his thought is rooted is not directed against the use of philosophy for the analysis of power. Rather, it is suspicious of the bravado behind the idea that philosophy can, and also must, reveal the hidden essence of things. What this means is that Foucault’s signature word – ‘power’ – is not the name of an essence that he has distilled but is rather an index to an entire field of analysis in which the work of philosophy must continually toil.

Mathematics a reality check?

Strangely, doing mathematics seems to be a bit of reality check for me. I still do mathematics off and on and am now trying a slightly different method than before. Last year, revising an unpublished paper, I thought that I saw some thing new that was mildly interesting. Off and on, I worked on it for six months and finally convinced myself after a few drafts. Then I went on a trip came back, it was difficult to get back to mathematics and easier to read other stuff. Finally after four months I slowly started looking at it again and could not understand much. After a few weeks, various steps involved emerged and I could see the general trend though not the details. Before when I was working it was generally rather intense and I used to loose appetite and often sleep until I was exhausted. This time, I started just meditating slowly about each step between doing other things at home and not continuously, even though the particular theme seemed to be in front of my mind most of the time. So, I would let it soak slowly until it seemed more and more clearer and so on with other steps. Then about how to put them together since there seemed different ways of doing it. At the moment much of it is becoming clearer without putting the pen on paper, and I am not loosing sleep. It remains to be seen what happens when I tried to write it down. And whether there is a lesson from this about learning and thinking about other topics.

'Foragers, farmers and fossil fulels' by Ian Morris

A short review by Robin Hanson.
A comprehensive 19 page review by Alberto Bisin
Abstract:

The book is a large-scale history of the world through the different modes of production humanity has adopted over time and their implications in terms of moral values. Morris argues that the predominant value systems of human societies are cultural adaptations to the organizational structures of the societies themselves, their institutions, and ultimately to their modes of production. In particular, the book contains a careful analysis of how the hunting-gathering mode of production induces egalitarian values and relatively favorable attitudes towards violent resolution of conflicts, while farming induces hierarchical values and less favorable attitudes towards violence, and in turn the fossil fuel (that is, industrial) mode of production induces egalitarian values and non-violent attitudes. 

The narrative in the book is rich, diverse, and ultimately entertaining. Morris’ analysis is very knowledgeable and informative: arguments and evidence are rooted in history, anthro- pology, archeology, and social sciences in general. Notheless, the analysis falls short of being convincing about the causal nature of the existing relationship between modes of production and moral value systems.

Terry Tao comments "I had learned about Meyer’s wavelet constructions as a graduate student while taking a course from Ingrid Daubechies.   Daubechies also made extremely important contributions to the theory of wavelets, but my understanding is that due to a conflict of interest arising from Daubechies’ presidency of the International Mathematical Union (which nominates members of the Abel prize committee) from 2011 to 2014, she was not eligible for the prize this year, and so I do not think this prize should be necessarily construed as a judgement on the relative contributions of Meyer and Daubechies to this field.  (In any case I fully agree with the Abel prize committee’s citation of Meyer’s pivotal role in the development of the theory of wavelets.)"

About migrants

Much of what we know about migration is wrong from Der Spiegel
But there is also news like this "Over the last decade, an estimated $3.8 trillion in capital has left China. Net foreign direct investment over the same period of time has amounted to $1.3 trillion, leaving the country with a net loss."

Rahul Banerjee finds himself on the dais with a District collector

Saeed Khan, was an anarchist to the core and despite being part of an organisation he was always in confrontation with it. He was a journalist of the Hindustan Times, Indore edition, which has now wound up and he believed in staying close to the ground. So much so that he did not own any motorised vehicle and moved around on foot and public transport even though he had an Iphone in his pocket which he used to surf the world at a drop of the hat. I was invited to speak a few words about him in today's commemoration and that is how I landed up on the dais. The commemoration event had been well advertised on FB and Twitter and reading this, the District Collector of Indore too came uninvited and was called up to the dais and that is how we were together there.
The Collector said that in his earlier stint as the Municipal Commissioner in Indore, he had been accosted on many occasions by Saeed who was then diligently pursuing all the misplanning and malimplementation that was manifesting itself in the development of Indore city. He said, that in Saeed, for the first time he met a journalist who did deep research on his stories and would fearlessly flay administrative inefficiency. He also said that normally he is continually invited to chair or take part in various public meetings by organisations and had to refuse them most of the time but this is the first time in his thirteen year career as an administrator that he was attending a meeting like this uninvited simply because he couldn't get over the fact that Saeed was not there anymore and he wanted to share his respect for him.
From a write up by Rahul Banerjee on Saeed Khan

Some articles on quantification

The invention of 'The Economy'', dates it roughly to the mid twentieth century. But the trend for quantification started much earlier in the west, even before the sixteenth century as this article on Quantification suggests. And The risks of quantification.

Tim Hartford on the problem with facts

The problem with facts, slightly longish but well worth a couple of reads, I think.
P.S.  My tentative view. We are in some ways prediction machines for our survival; that is we store information and try to predict to find our way around. The problem is our limited capacity to store quickly recallable information. This is where we have developed short cuts often based an emotions like disgust. The problem is accentuated even for experts with the modern information overload. Atul Gawande describes one such instance in Cowboys and pit crews. Of course there are attempts to see patterns using big databases and so on but these are not amenable to the common man. So we need chains of dissemination to reach the common man to make reasonable judgements. But these chain are also manned by people with similar biases and self interests. So perhaps what we need are people for whom the interests of other people are more important than their own, perhaps people like Asron Swartz or deliberate attempts to cultivate such attitudes.

In India, I find that biographical writing from admirers tend to make characters like Ambedkar to Gandhi to Ghantasala either godlike figures or from full of polemics from critics. Here is one of a player I admired, warts and all. More about Pistol Pete at several places including a few books like this Mark Kriegel

Two on amazon.com

The first Amazon is going to kill more American jobs than China did from Market Watch. The second a detailed study ( which I only browsed) from the Yale Law Journal by Lena M.Khan:
ABSTRACT. Amazon is the titan of twenty-first century commerce. In addition to being a retailer, it is now a marketing platform, a delivery and logistics network, a payment service, a credit lender, an auction house, a major book publisher, a producer of television and films, a fashion designer, a hardware manufacturer, and a leading host of cloud server space. Although Amazon has clocked staggering growth, it generates meager profits, choosing to price below-cost and expand widely instead. Through this strategy, the company has positioned itself at the center of e-commerce and now serves as essential infrastructure for a host of other businesses that depend upon it. Elements of the firm’s structure and conduct pose anticompetitive concerns—yet it has escaped antitrust scrutiny.
This Note argues that the current framework in antitrust—specifically its pegging competition to “consumer welfare,” defined as short-term price effects—is unequipped to capture the architecture of market power in the modern economy. We cannot cognize the potential harms to competition posed by Amazon’s dominance if we measure competition primarily through price and output. Specifically, current doctrine underappreciates the risk of predatory pricing and how integration across distinct business lines may prove anticompetitive. These concerns are heightened in the context of online platforms for two reasons. First, the economics of platform markets create incentives for a company to pursue growth over profits, a strategy that investors have rewarded. Under these conditions, predatory pricing becomes highly rational—even as existing doctrine treats it as irrational and therefore implausible. Second, because online platforms serve as critical intermediaries, integrating across business lines positions these platforms to control the essential infrastructure on which their rivals depend. This dual role also enables a platform to exploit information collected on companies using its services to undermine them as competitors. 
This Note maps out facets of Amazon’s dominance. Doing so enables us to make sense of its business strategy, illuminates anticompetitive aspects of Amazon’s structure and conduct, and underscores deficiencies in current doctrine. The Note closes by considering two potential regimes for addressing Amazon’s power: restoring traditional antitrust and competition policy principles or applying common carrier obligations and duties.

Facebook friends

Some Facebook friend seem frustrated with me. They probably consider me as elite material and not doing my bit. But the problem is that I felt most people I met were better than me in some respect or other and I really do not have much to say to them. Secondly, I find things do not come naturally to me. I have to learn, think and work hard to make any 'progress'. How do I know that I make progress in a topic? Most of my time is spent in mathematics where there are accepted norms of proof if you ignore some fundamental contradictions. Generally afte some thing is written, a consensus whether it is correct or not is reached. Since I have a track record with papers written as far back as seventies still being referred to, I assume that I made some progress there.

But in outside areas like social sciences; where I spend a lot of time these days thinking about development issues, it is much more problematic. As words get farther from concrete things, they seem to have a band width, and we seem to mean slightly different things by the same word. I think that this is what makes communication possible and also considerable confusion. So, a conclusion may be that universal models may not be possible and if one is close to real things, some understanding may be possible in specific contexts. I think that mutually understandable language is needed here. Here I tend towards language understandable to common people due to my interest in poverty and development. A case study may be the relative influences of Vemana and Srinadha on the Telugu populace.

Going back to development, I will consider just one aspect of elites. As Brad DeLong said (quoted in the previous post) about moderns "...they engage in complicated symbolic interactions that have the emergent effect of distributing status and power...". It seems to me that this is where the problem is. According to Gabriel Palma in as many as 140 countries, the top ten percent and bottom forty percent together share half the income. As the share of the top ten percent increases which seems to be currently the case, it is at the expense of the bottom forty percent. And the majority of the elites are in the top percent and they like others look after their self interests. I consider this a problem. And that is why I prefer to among the non-elites.

Quotes from Brad DeLong

"But since 1750 or so things have been different. The pace of economic change has been so great as to shake the rest of history to its foundation. For perhaps the first time, the making and using the necessities and conveniences of daily life--and how production, distribution, and consumption changed--has been the driving force behind a single century’s history. Even in the most long-established of professions, the pattern and rhythm of work life today is so very different from that of our ancestors as to be almost unrecognizable. It is these changes in production and also in home life and consumption, and the reactions to them, that make up the center ring action of the history that has made us who we are" and "What do modern people do? Increasingly, they push forward the corpus of technological and scientific knowledge. They educate each other. They doctor each other. They nurse each other. They care for the young and the old. They entertain each other. They provide other services for each other to take advantage of the benefits of specialization. And they engage in complicated symbolic interactions that have the emergent effect of distributing status and power and coordinating the seven-billion person division of labor of today’s economy. We have crossed a great divide between what we used to do in all previous human history and what we do now. Since we are not in the realm of necessity, we ought to be in the realm of freedom."

Rahul Banerjee on the recent U.P.elections

Congress is hoist with its own petard "o as long as proportional representation is not introduced in India, there is little chance of individuals or parties fighting for true people oriented development, making any headway in electoral politics. However, there is no need for disillusionment and fear but instead more commitment is needed to pursue grassroots activism which is increasingly becoming a rarity with time." There is also a discussion on his wall.
