Hauser will not teach Harvard Extension School class

August 31, 2010

From the Boston Globe, by Carolyn Y. Johnson August 31, 2010:

Harvard psychology professor Marc Hauser will not be teaching a Harvard Extension School class on Cognitive Evolution that was scheduled to start today, or a spring class called “The Moral Sense: From Genes to Law.”

Hauser, who was found by an internal Harvard investigation to have engaged in scientific misconduct, is on a one-year leave from research and teaching duties in the university’s main Arts and Sciences school, but the Globe reported earlier this month that he still planned to teach in the extension school.

But the extension school sent an e-mail to students who were enrolled in the class explaining that the course has been cancelled “at the request of the instructor, Professor Marc Hauser.”

If Hauser pulled out does it mean that Harvard found no problem with his continuing the classes?

Peer-review evolves

August 31, 2010

A welcome development.

The traditional method, in which independent experts evaluate a submission, often under a veil of anonymity, can take months, even years. Clubby exclusiveness, sloppy editing and fraud have all marred peer review on occasion. Anonymity can help prevent personal bias, but it can also make reviewers less accountable; exclusiveness can help ensure quality control but can also narrow the range of feedback and participants.

Just as “consensus” science is meaningless so is expecting good science to be subject to a “democratic process”. But when reviewers show bias (in acceptance or in rejection) or misuse and hide behind the cloak of anonymity and are not required to be accountable then Hausergate and Climategate become inevitable.

From Wikipedia: http://en.wikipedia.org/wiki/Peer_review

Richard Horton, editor of the British medical journal The Lancet, has said that

The mistake, of course, is to have thought that peer review was any more than a crude means of discovering the acceptability — not the validity — of a new finding. Editors and scientists alike insist on the pivotal importance of peer review. We portray peer review to the public as a quasi-sacred process that helps to make science our most objective truth teller. But we know that the system of peer review is biased, unjust, unaccountable, incomplete, easily fixed, often insulting, usually ignorant, occasionally foolish, and frequently wrong.

The New York Times reports (http://www.nytimes.com/2010/08/24/arts/24peer.html?_r=1):

Now some humanities scholars have begun to challenge the monopoly that peer review has on admission to career-making journals and, as a consequence, to the charmed circle of tenured academe. They argue that in an era of digital media there is a better way to assess the quality of work. Instead of relying on a few experts selected by leading publications, they advocate using the Internet to expose scholarly thinking to the swift collective judgment of a much broader interested audience.

“What we’re experiencing now is the most important transformation in our reading and writing tools since the invention of movable type,” said Katherine Rowe, a Renaissance specialist and media historian at Bryn Mawr College. “The way scholarly exchange is moving is radical, and we need to think about what it means for our fields.”

That transformation was behind the recent decision by the prestigious 60-year-old Shakespeare Quarterly to embark on an uncharacteristic experiment in the forthcoming fall issue — one that will make it, Ms. Rowe says, the first traditional humanities journal to open its reviewing to the World Wide Web. Mixing traditional and new methods, the journal posted online four essays not yet accepted for publication, and a core group of experts — what Ms. Rowe called “our crowd sourcing” — were invited to post their signed comments on the Web site MediaCommons, a scholarly digital network. Others could add their thoughts as well, after registering with their own names. In the end 41 people made more than 350 comments, many of which elicited responses from the authors. The revised essays were then reviewed by the quarterly’s editors, who made the final decision to include them in the printed journal, due out Sept. 17.

“Knowledge is not democratic,” said Michèle Lamont, a Harvard sociologist who analyzes peer review in her 2009 book, “How Professors Think: Inside the Curious World of Academic Judgment.” Evaluating originality and intellectual significance, she said, can be done only by those who are expert in a field.

At the same time she noted that the Web is already having an incalculable effect on academia, especially among younger professors. In her own discipline, for instance, the debates happening on the site Sociologica.mulino.it “are defined as being frontier knowledge even though they are not peer reviewed.”

The most daunting obstacle to opening up the process is that peer-review publishing is the path to a job and tenure, and no would-be professor wants to be the academic canary in the coal mine.

Et tu IAC? Time for Pachauri to exit.

August 30, 2010

The IAC report is in.

And this is a report by a “friend”.

It is time for Pachauri to leave the reform and the improvement of the IPCC (assuming such a politically charged body can ever be reformed) to somebody else since he has clearly not been up to the task.

The Telgraph: The UN’s Intergovernmental Panel on Climate Change should only make predictions when it has solid scientific evidence and avoid straying into policy advocacy, a group of national science academies has warned in a report.

The report said the chairman of the IPCC should be limited to one six year term. Its current head Rajendra Pachauri of India, is in the middle of his second term. It called for an overhaul of the panel’s management, including the creation of an executive committee that would include people from outside the IPCC. Regarding the errors that appeared in the IPCC reports, the review group’s report called for stronger enforcement of the panel’s scientific review procedures to minimise future mistakes.

Professor Mike Hulme, a professor of climate change at the University of East Anglia, is due to deliver a keynote lecture to the Royal Geographical Society Annual conference this week in which he will call for a dramatic changes to the way the IPCC operates. Speaking ahead of his lecture, he said: “The IPCC has not sufficiently adapted to the changing science and politics of climate change, nor to the changing expected and demanded role of science and expertise in society. “The IPCC’s approach of seeking consensus obscures and constricts both scientific and wider social debates about both knowledge-driven and value-driven uncertainties that surround climate change politics.”

Rajendra Pachauri

The BBC: UN climate body ‘needs reforms’, review recommends.

Among the IAC committee’s recommendations was that the UN body appoint an executive director to handle day-to-day operations and speak on behalf of the body. It also said the current limit of two six-year terms for the chair of the organisation is too long. The report also suggests the UN body establish an executive committee which should include individuals from outside the IPCC or even outside the climate science community in order to enhance the UN panel’s credibility and independence.

The use by the IPCC of so-called “grey literature” – that which has not been peer-reviewed or published in scientific journals – has been subjected to particular scrutiny of late, partly because this type of material was behind the glacier error. The committee said that such literature was often relevant and appropriate for inclusion in the IPCC’s assessment reports. But it said authors needed to follow the IPCC’s guidelines more closely and that the guidelines themselves are too vague.

Bishop Hill:Furthermore, by making vague statements that were difficult to refute, authors were able to attach “high confidence” to the statements. The Working Group II Summary for Policy Makers contains many such statements that are not supported sufficiently in the literature, not put into perspective, or not expressed clearly.”

Climategate and Hausergate: Different routes to the faking of science

August 30, 2010

Clearly academia can only reflect surrounding society. Scientists are not saints and political motives, financial greed and fame-seeking will be just as prevalent within academia as in the surroundings. Frauds and fakers will inevitably exist. Nevertheless it is peer review – by colleagues within the organisation and within the peer-review process – which is supposed to maintain the quality of scientific work but perhaps it must now be expanded to protect and maintain the integrity of scientific work as well. Reviewers cannot continue to use the independence of the review process as an excuse to remain cocooned within their comfort zones of anonymity. They do need to stand up and be counted.

In recent months two very different scandals in the scientific world but both relying on fake science have surfaced. In one peer-review has been lax and in the other it has been perverted to a cause.

In the case of Climategate (and the IPCC), the peer-review process was perverted to falsify scientific conclusions and suppress dissent in support of a particular political (and financial) agenda.

In the case of Hausergate predetermined conclusions were supported by falsified data which were then endorsed by the peer-review process to make non-science seem to be science. The financial motive is probably only secondary to the primary motive of seeking acclaim and reputation.

http://www.stochasticgeometry.ie/wp-content/uploads/2009/10/snakeoil.jpg?w=257

In both cases the normal sequence of the scientific method of

Question > research >hypothesis > experiment /test > analysis > conclusion

has been distorted.

In the case of Climategate a small clique of academics perverted the peer-review process to control and prevent the publication of opposing views. The IPCC (where the authors were often the same academics with a few charlatans, railway engineers, thrill seekers, politicians and financiers thrown in for good measure) not only prevented the consideration of alternate views but went further by including non-peer-reviewed advocacy reports, newspaper articles and the like when they were favourable to their cause. Of course the IPCC is a political institution so perhaps it is asking too much to expect it to be a force to maintain scientific integrity.

“Since the IPCC gives Lead Authors the sole right to determine content and accept or dismiss comments, it is more like a weblog than an academic report.”

See “Fix the IPCC process” by Ross McKitrick at http://opinion.financialpost.com/2010/08/27/fix-the-ipcc-process/

An alarmist agenda was used to satisfy the greed associated with the Carbon Offset and Trading scams. Some data manipulation is also evident from the Climategate e-mails but the control of peer-review was the main tool used.

In the case of Marc Hauser he simply fabricated data to fit the conclusions he had already come to (and it is irrelevant that his theories or conclusions may or may not be correct). It is stated that he was publishing at the rate of a paper – each one peer-reviewed – every month for 4 years. Obviously not too difficult to do or too time-consuming  if data only had to be fabricated whenever needed. What were the peers and reviewers doing? Had his colleagues and reviewers no suspicions or doubts?

What is not clear is why Hauser felt it was advantageous to fake the science instead of doing the science. Clearly he could not have been as prolific if he had to actually do the science and perhaps account for data which did not support his  theories. It would seem therefore to be connected with the gaining of an academic reputation quickly and perhaps also with the financial benefits flowing from that.

But the message coming through is that peers and peer-review must be transparent and very much more rigorous. They cannot restrict themselves to quality control alone – which itself is not applied uniformly – and not take a position on the integrity of the work. Reviewers are effectively servants of the Journals they serve and the Journals too cannot escape responsibility for what they publish and what they choose not to.

Most detailed image of a sunspot ever by Big Bear

August 27, 2010

No wonder sunflowers are obsessed !!

Researchers at Big Bear Solar Observatory have tuned their adaptive optics array and achieved first light, capturing this image of a sunspot that is now the most detailed ever captured in visible light. The image was captured with Big Bear’s New Solar Telescope (NST), a brand new instrument (as the name implies) with a resolution of just 50 miles on the sun’s surface.
http://www.popsci.com/files/imagecache/article_image_large/articles/011-03410-01high.jpg

The NST is the precursor to an even-larger telescope, the Advanced Technology Solar Telescope (ATST), which will be constructed over the next decade, allowing Big Bear researchers to build a new kind of adaptive optics system known as multi-conjugate adaptive optics, that should provide them with a clear, distortion-free means of observing the sun from Earth in unrivaled detail.

Solar Flares may dampen radioactive decay on Earth !

August 24, 2010

A detective story from Stanford University News. http://news.stanford.edu/news/2010/august/sun-082310.html

When researchers found an unusual linkage between solar flares and the inner life of radioactive elements on Earth, it touched off a scientific detective investigation that could end up protecting the lives of space-walking astronauts and maybe rewriting some of the assumptions of physics.

Increasing whiskey production can save the environment

August 21, 2010

By-products from distilling whiskey produce a biofuel with 30% more power output than ethanol !

Using samples from the Glenkinchie Distillery in East Lothian, researchers at Edinburgh Napier University have developed a method of producing biofuel from two main by-products of the whisky distilling process – “pot ale”, the liquid from the copper stills, and “draff”, the spent grains. The new method developed by the team produces butanol, which gives 30% more power output than the traditional biofuel ethanol. It is based on a 100-year-old process that was originally developed to produce butanol and acetone by fermenting sugar. The team has adapted this to use whiskey by-products as a starting point and has filed for a patent to cover the new method. It plans to create a spin-out company to commercialise the invention. Butanol is superior to ethanol — with 25 – 30% t more energy per unit volume. The biofuel can also be introduced to unmodified engines with any gasoline blend, whereas ethanol can only be blended up to 85 percent and requires engine modification.

Professor Martin Tangney, who directed the project said that using waste products was more environmentally sustainable than growing crops specifically to generate biofuel. “What people need to do is stop thinking ‘either or’; people need to stop thinking like for like substitution for oil. That’s not going to happen. Different things will be needed in different countries. Electric cars will play some role in the market, taking cars off the road could be one of the most important things we ever do.”

“The production of some biofuels can cause massive environmental damage to forests and wildlife. So whisky powered-cars could help Scotland avoid having to use those forest-trashing biofuels,” said Dr Richard Dixon, of WWF Scotland.

“DRINK IT and then DRIVE IT” has a nice ring to it and  is something I could enjoy supporting.

Hausergate: An utter lack of ethics

August 19, 2010

Fiction passed of as science

Further revelations in The Chronicle of Higher Education provides sordid details about the Hauser paper published in 2002 in Cognition and which is now being retracted. But the pattern of behaviour described is that of an accomplished liar well-versed in creating bogus data. To become such an accomplished inventor of data must have taken years of practice.

For how long has Hauser been passing off works of fiction as works of science?

Hauser’s hectoring tone towards his research assistants to try and force his false interpretations on them are also very revealing. The author of Moral Minds exhibits an utter lack of ethics.

Rather than getting a year off to write another work of fiction should he not be required to return all the salary and grant money he has enjoyed as the fruits of his inventiveness?

Where are all the peers who have recommended his being published?

Document Sheds Light on Investigation at Harvard 1

An internal document, however, sheds light on what was going on in Mr. Hauser’s lab. It tells the story of how research assistants became convinced that the professor was reporting bogus data and how he aggressively pushed back against those who questioned his findings or asked for verification.

Climate models don’t need the sun – “Venus is similar to Earth” !!!

August 17, 2010

Japanese Spacecraft Approaches Venus

Venus Climate Orbiter “AKATSUKI”

This from NASA Science News:

[Global view of Venus]

Imamura is the project scientist for Akatsuki, a Japanese mission also called the Venus Climate Orbiter. The spacecraft is approaching Venus and will enter orbit on December 7, 2010. Imamura believes a close-up look at Venus could teach us a lot about our own planet.

“In so many ways, Venus is similar to Earth. It has about the same mass, is approximately the same distance from the sun, and is made of the same basic materials,” says Imamura. “Yet the two worlds ended up so different. We want to know why.”

Considering NASA’s own Venus fact sheet and the fact that Venus is about 41 million km closer to the sun it is – in the kindest interpretation – sloppy to permit a statement that “Venus is similar to earth.. approximately the same distance from the sun”.

“By comparing Venus’s unique meteorology to Earth’s, we’ll learn more about the universal principles of meteorology and improve the climate models we use to predict our planet’s future” says Imamura.

Of course the models will no doubt take into account that solar radiation on Venus is about  2688 J while the Earth receives 1365 J or perhaps the models don’t need the sun and will base everything on the heating effects of carbon dioxide.

I would have thought that it is the differences between Venus and Earth which can be revealing and to consider a distance of 41 million km closer to the sun as being negligible does not inspire confidence in any subsequent climate modelling.

“Hausergate” and the perversion of peer review

August 14, 2010

It would seem that  Marc Hauser fudged or exaggerated or imagined or just plain made up some of the results in at least 3 papers which were published after peer review.

Predictably, Harvard is being very reticent with information but as reported by The Boston Globe the university has assured the world that all necessary corrections will be made. Harvard University confirmed yesterday that it has examined concerns about scientific work by prominent psychology professor Marc Hauser and said it has “taken steps to ensure that the scientific record is corrected’’ in three journal articles for which he was a coauthor.

Also predictably others at Harvard are rationalising and taking a sympathetic view. Greg Laden says: “I know Marc Hauser, and I trust him.”

http://homelessmanspeaks.files.wordpress.com/2008/11/circling-wagons-nov-27-2008.jpg

Hauser himself is taking a year off as penance and to purge himself of his misconduct.

1. A 2002 paper published in the journal Cognition is being retracted by Hauser and two coauthors. The retraction notes that an internal Harvard examination found that the data do not support the findings.

The journal ( or is it magazine) and Elsevier need to now defend their editorial process. Who were the peers and what did they review?

2. Also called into question by the investigation is a 2007 paper in the journal Science. Ginger Pinholster, a spokeswoman for the journal, said that one of the coauthors — Justin Wood, a former graduate student at Harvard who now is an assistant professor of psychology at the University of Southern California — wrote a letter to the journal in late June. According to Pinholster, the letter stated that an internal investigation at Harvard found there were missing field notes and that the team at Harvard had recreated its research as a result. Science has yet to make a formal change to the article.

Did the missing notes ever exist? Time for Science to open up.

3. A 2007 paper in the Proceedings of the Royal Society B has already been corrected, because of missing video records and field notes. Earlier this week, Victoria Millen, publishing editor of the British journal, confirmed that the authors contacted the journal last month and informed it of the investigation. The correction notes that incomplete video records and field notes were collected by “the researcher who performed the experiments,’’ a scientist named David Glynn, who has not responded to multiple e-mail and voicemail messages.

Hausergate and Climategate and all its associated “gates” show that the peer review process is sufficiently perverted and corrupted that it needs an overhaul. It is time for the assenting and dissenting peers to stand up and be counted and not hide behind the skirts of anonymous independance.

The Harvard statement said that in cases like Hauser’s, Harvard reports its findings to federal funding agencies, which do their own reviews.

But Harvard cannot pass the buck.
