Nature’s laws may vary across the universe – and so what if they should

November 5, 2011

There were headlines last week because according to a new paper published  in Physical Review Letters it may be that one of the “laws of nature” may vary across the Universe. Observations from two large telescopes pointed in different directions of the universe seem to show that the electromagnetic force which is measured by the fine structure constant, α,  may be different in different parts of the universe.

Indications of a spatial variation of the fine structure constant, by J. K. Webb, J. A. King, M. T. Murphy, V. V. Flambaum, R. F. Carswell and M. B. Bainbridge, Phys. Rev. Lett., 107, 191101, 2011, http://arxiv.org/abs/1008.3907 

Since the “laws of nature” and the “laws of physics” are merely expressions of observed regularities in our observable time and space they are – of necessity – empirical conclusions. Since we – as yet – have no idea “why” the “laws” we observe should be as they are and why the “fundamental constants” take the values they do, it seems to me unremarkable that there should be areas of time or space (not observed as yet) where these “laws” – as we have formulated them – do not hold exactly. There may well be errors of observation of course but observations made correctly must trump theories and models – no matter how simple or beautiful they might be.

The difference between a scientist and an engineer

July 15, 2011

I like this practical  (rather than philosophic) formulation:

A scientist observes and describes what is but which has not been observed before, or causal relationships between existing or new observations or – when necessary – creates the language to make such descriptions possible.

An engineer uses what is together with known causal relationships to create artefacts.

Where such artefacts are created for the first time he is also an inventor.

“for your own good” is the most arrogant phrase there is

July 10, 2011

The height of arrogance is when I am told by someone else that I should do something or not do something “for your own good”.

Be it a doctor or a lawyer or an environmental campaigner or a civil servant or a politician or a government,  the phrase raises my hackles.

It presumes too much.

It does not convince.

It is dictatorial.

It imposes one person’s values on someone else.

It is a denial of the subject’s most deep-seated and fundamental value of deciding what constitutes “good”.

I am inclined to think that the most fundamental human characteristic is that

any – and every – human can determine what is “good”

The needs of others and surrounding society and definitions of basic human rights can circumscribe this but cannot – by diktat – take away this fundamental value which is I think integral to being an individual. By corollary any entity which cannot decide what is good and then distinguish between “good” and “bad” does not then qualify for the label “human individual”.

This leads me to paraphrase Descartes’

“cogito ergo sum” (I thinktherefore I am)  

to be instead:

I decide what is “good” and can distinguish that which is “bad”.

Therefore I am.

Saints galore – but plenty of room in Heaven for many more

May 1, 2011

BBC:

The late Pope, John Paul II, has been officially beatified at a ceremony at the Vatican in front of hundreds of thousands of Catholic faithful. Among those at St Peter’s Square is French nun Marie Simon-Pierre, who says she was cured of Parkinson’s Disease. Her apparently miraculous cure is part of the case for the beatification, the last stage before sainthood.

It comes amid criticism of the Church for the speed of the beatification and the clerical child sex abuse scandal. Much of the abuse occurred while John Paul II was Pope, from 1979-2005, and the Church has been criticised for not doing enough to punish those found responsible.

Police in Rome estimated that one million people had come to the city for the event, including large numbers of pilgrims from the late Pope’s native Poland. 

St Peter’s Square, in the Vatican, was packed, with the faithful waving banners and flags as Pope Benedict XVI declared his predecessor blessed, or beatified. Rome has not seen crowds of this size since the death of Pope John Paul II six years ago when some three million pilgrims converged on the Italian capital, says the BBC’s Vatican correspondent David Willey.

Zimbabwean leader Robert Mugabe was among those attending the beatification. A Roman Catholic, he was given special permission by the EU to fly to Italy despite being the subject of a travel ban.

Recent beatifications

  • Oct 2003: Mother Teresa, 1910-1997
  • March 2008: Marianna Donati, 1848-1925
  • Sept 2008: Michal Sopocko, 1888-1975
  • Sept 2010: John Henry Newman, Cardinal, 1801-1890

Steps to sainthood

The process, which cannot begin until at least five years after the candidate’s death unless the pope waives that waiting period, involves scrutinising evidence of their holiness, work and signs that people are drawn to prayer through their example:

  • First stage: individual is declared a ‘servant of God’
  • Second stage: individual is called ‘venerable’
  • Third stage (requires a miracle attributed to candidate’s intercession): beatification, when individual is declared blessed
  • Fourth stage (requires a further authenticated miracle): candidate is canonised as a saint for veneration by Church
But the beatification, canonisation and recognition of Saints is a highly political process – and always has been. It is the Catholic Church’s version of an Honours system and canonisation carries with it many benefits for the region or Order or community the Saint comes from. There are also certain business benefits which flow as a consequence of sainthood and usually associated with the viewing of relics, sales of souvenirs and the promotion of religious tourism.

John Paul reformed the sainthood process in 1983, making it faster, simpler, and cheaper. The office of “Devil’s advocate” – an official whose job was to try to knock down the case for sainthood – was eliminated, and the required number of miracles was dropped.

The idea was to lift up contemporary role models of holiness in order to convince a jaded secular world that sanctity is alive in the here and now. The results are well known: John Paul II beatified and canonised more people than all previous popes combined.

There are over 10,000 named saints and beatified people from history, the Roman Martyrology and Orthodox sources, but no definitive head count. 

The Catholic Church teaches that it does not, in fact, make anyone a saint. Rather, it recognizes a saint. In the Church, the title of Saint refers to a person who has been formally canonized (officially recognized) by the Catholic Church, and is therefore believed to be in Heaven. By this definition there are many people believed to be in Heaven who have not been formally declared as saints (most typically due to their obscurity and the involved process of formal canonization) but who may nevertheless generically be referred to as saints. All in Heaven are, in the technical sense, saints, since they are believed to be completely perfected in holiness. Unofficial devotions to uncanonized individuals take place in certain regions. Sometimes the word “saint” is used to refer to Christians still sojourning here on earth.

Yesterday apart from a few minutes on the TV news I managed to avoid watching the massive political PR exercise represented by the Royal Wedding. Today I watched a few minutes of the beatification ceremonies and even if it sounds cynical, I could not help thinking that it was just another political and stage-managed PR exercise. No doubt the ritual and the pomp and the ceremony on display at both events fulfils some deep-seated human needs. 

It is fortunate that Heaven lies in the realm of the infinite and there can be little cause to worry about over-crowding (and again I can’t help wondering if there are any cases of some unfortunate people who have been recognised and proclaimed as Saints but who – for God knows whatever reason – are languishing in the Other Place).

A “Culture of Courage” in management — from “Essence of a Manager”

March 31, 2011

“Without fear being present, bravery and courage do not appear on stage.”

From Chapter 7,  Essence of a Manager

Courage is the subordination of fear to purpose.

A manager is perforce required to take risk. Every judgment or selection or decision he takes results in actions with an uncertain outcome. The presence of risk and the uncertainty about results inevitably give rise to apprehensions and fears. It is a manager’s task to subordinate such fears and continue with judiciously chosen actions towards his objectives. Extending his capability for taking actions and stretching the envelope of actions available to him are key elements of his core competence. It is his courage which enables him to operate in new and untried areas which are outside his comfort zone and thereby generate a steady stream of brave actions.

A manager can create a “courage space” around himself and as this expands and grows and meets other spaces of courage a “culture of courage” can develop within an organisation. ……

It has always struck me that super-heroes must be particularly devoid of courage since their fantastic abilities must mean that they have little opportunity to feel any fear. ….

Success and goodness in management

February 21, 2011

From EOAM

Essence of a Manager

Success is transient. Just like profit or cash-flow – it is over once it has been recognised. Goodness lasts longer – it is like a balance sheet item.”

“To be able to deal with bureaucrats in India it is necessary to understand that it is the potential for blame which has to be minimised while the potential for personal gain has to be maximised”.

Drawing the line between science and faith

January 9, 2011

Steve McIntyre takes up another case of  somebody publishing a paper but refusing access to the data the paper is said to be based on at http://climateaudit.org/2011/01/06/more-data-refusal-nothing-changes/.

I have always found my simple and absolutely reliable demarcator between science and faith as being the words ” I believe that….”. The moment any statement is a matter of  “belief” rather than ” a conclusion drawn from the evidence” it becomes a matter of faith rather than of  “science”.

The moment an author cannot – for whatever reason – provide the data he has used then he is asking the reader to rely on “faith” or “trust” that the data does exist and is not faked or imagined or invented. For the reader the matter immediately descends to becoming a question of “belief” in the author if nothing else. And the author is surely not God to command an unquestioning belief.

  • Whenever an author refuses access to his data he reduces his own conclusions from being matters of science to becoming matters of “faith”.
  • When such a paper is said to be peer-reviewed then it reduces the group of peers to be little more than the acolytes to a faith.
  • When a journal publishes a paper without insisting that the data be archived and accessible then it reduces the journal in which the paper is being published to being no more than the parish magazine for a cult.

Hausergate: In scientific misconduct “confirmation bias” or “fudging data” are equally corrupt

January 2, 2011

The Scientific American carries an article about the Marc Hauser case at Harvard. (Marc Hauser was found to have committed 8 cases of scientific misconduct).

Scientific American

Scott O. Lilienfeld argues that Hauser may only be guilty of “confirmation bias” and that it is premature to ascribe deliberate wrongdoing to him:

Hauser has admitted to committing “significant mistakes.” In observing the reactions of my colleagues to Hauser’s shocking comeuppance, I have been surprised at how many assume reflexively that his misbehavior must have been deliberate. For example, University of Maryland physicist Robert L. Park wrote in a Web column that Hauser “fudged his experiments.” I don’t think we can be so sure. It’s entirely possible that Hauser was swayed by “confirmation bias”—the tendency to look for and perceive evidence consistent with our hypotheses and to deny, dismiss or distort evidence that is not.

The past few decades of research in cognitive, social and clinical psychology suggest that confirmation bias may be far more common than most of us realize. Even the best and the brightest scientists can be swayed by it, especially when they are deeply invested in their own hypotheses and the data are ambiguous. A baseball manager doesn’t argue with the umpire when the call is clear-cut—only when it is close.

Scholars in the behavioral sciences, including psychology and animal behavior, may be especially prone to bias. They often make close calls about data that are open to many interpretations…….

………. Two factors make combating confirmation bias an uphill battle. For one, data show that eminent scientists tend to be more arrogant and confident than other scientists. As a consequence, they may be especially vulnerable to confirmation bias and to wrong-headed conclusions, unless they are perpetually vigilant. Second, the mounting pressure on scholars to conduct single-hypothesis-driven research programs supported by huge federal grants is a recipe for trouble. Many scientists are highly motivated to disregard or selectively reinterpret negative results that could doom their careers.

But I am not persuaded. When “eminent” scientists use their position and power to indulge in “confirmation bias” it is merely a euphemism for what is still cheating by taking undue advantage of their position. It is “corruption” in its most basic form. I reject the notion that such “confirmation bias” is a form of  “unwitting behaviour”. It may well be behaviour which resides in the sub-conscious but that is not “unwitting” behaviour. Neither is it excusable just because it may be in the sub-conscious. It gets into the sub-conscious only because the conscious allows it to do so. When any behaviour residing in the sub-conscious conflicts with the values and morality of an individual it is inevitably ejected into the conscious.  Being sub-consciously immoral but consciously moral is not feasible.

In the case of Marc Hauser, even assuming that his faults were due to “confirmation bias” then either it was behaviour which remained entirely in the sub-conscious in which case his values and morality are suspect, or it was triggered into the conscious and he continued anyway in which case it was simple cheating.

Why cannot a concept of tort or “product liability”apply to scientists?

November 28, 2010

Cases of scientific misconduct do not seem to lead to any significant sanctions. Scientists are not subject to the codes of ethics that other professions have (even if they are not always complied with). Lawyers and doctors and engineers can be “disbarred” or otherwise forbidden from practising their professions when found guilty of incompetence or fraud.  Why then can a physicist or a chemist or a biochemist not be subject to the same professional sanctions for misconduct? Learned Institutes of Physics or Chemistry or Mathematics rarely get involved in the ethics breaches of their members. Scientists also need to be held responsible (liable) for their work and in cases of fraudulent science or misconduct, the sanctions applied need to be seen to be in balance with the extent of the offence.

There have been many cases of scientific misconduct where the offender seems to get little more than a slap on the wrist or a mild reprimand. In some cases they leave one institution and merely move to another. Their degrees are rarely revoked and they usually continue “working” or faking work in some other institution.

Retraction Watch addresses the details of the case of the fraud committed by Dr Jatinder Ahluwalia at University College London which led to the retraction of a paper in Nature.

Earlier this month, we posted an item about the retraction of a 2004Nature paper, “The large-conductance Ca2+-activated K+ channel is essential for innate immunity.” (That post was followed up with provocative comments from a researcher not affiliated with the authors, about what should happen to papers whose results can’t be replicated.)

One of the paper’s authors, Jatinder Ahluwalia, hadn’t signed the retraction, and the notice referred to “Supplementary Information” that hadn’t yet been made available. Today, University College London (UCL) posted that supplementary information, which was the report of a panel that investigated charges of research misconduct against Ahluwalia. That report fills in a lot of details about what preceded the retraction.

UCL’s investigation found that Ahluwalia:

  • falsified the results of experiments conducted by him, on UCL premises, thereby committing research fraud, as defined by paragraph 1.1.iv of the UCL Procedure for Investigating and Resolving Allegations of Misconduct in Academic Research. It was alleged that Dr Ahluwalia altered the numbering of files of research results so as to misrepresent the results of experiments conducted by him;
  • further falsified and misrepresented the results of experiments conducted by him, on UCL premises, by the use of materials other than those specified in the reports of the results of those experiments, thereby committing research fraud, as defined by paragraph 1.1.iv of the UCL Procedure for Investigating and Resolving Allegations of Misconduct in Academic Research;
  • interfered with the experiments of others so as to distort their results, thus falsifying the results of research experiments conducted by others employed by UCL on UCL premises, thereby committing research fraud, as defined in paragraph 1.1.iv of the UCL Procedure for Investigating and Resolving Allegations of Misconduct in Academic Research. It was alleged that Dr Ahluwalia deliberately contaminated chemicals used by other researchers in their experiments so as to falsify the results of those experiments, in order to conceal the falsification by him of the results of his own experiments.

Dr Ahluwalia is currently employed as a Senior Lecturer & Programme leader in BSc & MSc Pharmacology at the School of Health and Biosciences, University of East London,  Stratford Campus, Romford Road, London E15 4LZ, United Kingdom. For having committed fraud and engaged in sabotage and even though he is no longer employed by UCL, it does not seem that his behaviour has led to any significant sanctions.

Recently a Harvard University investigation found its high-profile Professor Marc Hauser guilty of 8 counts of misconduct and sent him on a year’s “book leave” and he will resume his activities next year. He does not lose tenure and his degrees are not revoked and the sanction seems relatively mild in relation to his behaviour.

The product that researchers and scientists produce is publications – mainly as papers published in scientific journals and as books. Scientific misconduct (whether plagiarism or faking data or inventing data or cherry picking data) leads occasionally to dismissals (but not always) and generally very little else. It seems to me that the concept of tort or “product liability” should be applicable to the work of scientists and researchers where their work is the result of faking data, fraud or other misconduct since it would be work that “had not been done in good faith”. Tort would apply because the ramifications of their misconduct would extend far beyond their employment contracts with their employers.

Tort  (from Wikipedia) is a wrong:

that involves a breach of a civil duty owed to someone else. It is differentiated from criminal wrongdoing which involves a breach of a duty owed to society, and also does not include breach of contract. Tort cases may comprise such topics as auto accidents, false imprisonment, slander and libel, product liability (such as defectively designed consumer products), and environmental pollution (toxic torts).

Clearly a researcher has a civic duty to his co-workers, his department, his institution, his publishers and to the global community working in the same field. Scientific misconduct is a clear breach of these duties and any such researcher must then be both accountable and liable. Sanctions in such cases must be commensurate and seen to be commensurate with the offence. A year’s sabbatical from Harvard or merely moving across town to be employed at another university does not seem to be in balance with the weight of the misconduct.

The employment contract of a researcher with any institution no doubt has the appropriate language which allows sanctions (including dismissal) for breach of contract. However the liability of a fraudulent researcher – especially with published papers and books – goes beyond a simple breach of contract with his employer and extends to the entire community of workers in the field and even to all readers who may be influenced by the fraudulent work. For commensurate sanctions to be possible it becomes necessary for the concept of tort to be introduced and for  “product liability” to reside with the researcher whereby he can be held accountable by the entire audience his “product” is addressed to.

Authors of scientific papers and books need to be responsible and liable for their products.
