Short budget comment

Costello provides vision beyond the pork-barrelling - Editorial - Opinion

If even The Age has an editorial with a heading like that approving of the Budget, it can't be a bad one.

One for every backyard

Clean Energy / Infinia Corporation

With funding for solar power expected to be increased in tonight's budget, I wonder whether home based solar thermal will ever become much of an option. I quite like the look of the system at the link above, which is still (unfortunately) not yet on the market.

I am a little dubious about solar cells on the roof because of their limited life, and the danger from hail storms. I am guessing that a solar thermal system may be more easily repaired if it suffers storm damage.

Proof of cold fusion?

DailyTech - Navy Heats Up Cold Fusion Hopes

There's no indication that the type of could fusion allegedly shown here will end up being useful, but it would still be good to see an idea that has been so attacked by other scientists proved true.

On other blogs...

1. Probably everyone who reads me also reads Tim Blair. Still, I think that in his most recent post he comes up with up his funniest line for a long time (after quoting from the NYT):
The children are all too familiar with the apocalyptic warnings of climate change. “A lot of people are going to die” from global warming, a 9-year-old girl from Harlem announced at one point. And a 7-year-old boy from Park Slope said with a quiet lisp, “When you use too much electricity, it kills animals.”
Well, it does if you hook up the electrodes right.
2. Andrew Bolt has a good post on the pessimism of science fiction, brought on by recently re-watching Blade Runner. His conclusion:
Yes, it’s only a film, but it also fits a pattern of imagining of our future.

We actually wind up not much different in our wants, and not less vigilant on the whole against threats, than is often feared. We remain in the West extremely inventive, and driven more by the wishes of the public than the demands of the leaders.

That probably explains why artists and “seers” so often get us wrong, and imagine us becoming in time so much gloomier, oppressed, bullied, atrophied and poor than we inevitably and eventually turn out. In reminding us of this, Blade Runner is a comfort.

True. I also have heard Orwell's 1984 being read on Radio National recently, while I have been driving around town. It reminded me how much I disliked that book, both from a stylistic point of view (I think it is plain awful writing,) and for its ridiculous over-reach in the dystopia it paints. By taking aspects of totalitarianism, which were bad enough in their current form when Orwell wrote, and then exaggerating them wildly with an imagined technology which is still off the mark, combined with a way of writing characters which robbed them of any realistic humanity, the effect became that I just could not take it seriously. (Even with a one child policy, did China develop an "Anti-sex League"? )

3. Zoe Brain has brought to my attention the very enjoyable site Paleo-Future, which seems devoted entirely to looking at how the future has been imagined in the past. (I think it has been mentioned at Boing Boing before, but maybe I didn't follow the link.) I love this sort of stuff, growing up as I did in the (generally) optimistic 1960's, and expect to visit there regularly.

More icky moments in medical history...

Found via Arts & Letters Daily, there's book out called "Impotence - a Cultural History". In the Daily Telegraph review, there's an amusing list of odd impotence cures through history. One that I found odd because it is so specific is this:

...according to Ovid the "right molar of a small crocodile worn as an amulet guarantees erection in men".

Not just any crocodile molar, evidently, but the one on the right. How did the ancients come up with some of this stuff?

The other link from Arts & Letters is to an extract from the book itself, from which one can read a little about early experiments in testicular transplant:

The first experiment in grafting an entire testicle was performed by Dr. G. Frank Lydston on himself, on January 16, 1914. Expressing his disappointment that vulgar prejudices heretofore had prevented the exploitation of the sex glands of the dead, Lydston coolly reported how he transplanted into his own scrotum a suicide victim’s testicle. [p. 186]

L. L. Stanley, resident physician of the California state prison in San Quentin, reported in 1922 that he had first implanted testicles from executed convicts and then moved on to inject into his subjects via a dental syringe solutions of goat, ram, boar, and deer testicles. Altogether he made 1000 injections into 656 men. Stanley had been inspired by work of Serge Voronoff, an eminent Russian-born medical scientist working at the Collége de France. Voronoff in 1919 scandalized many by transplanting the testes of chimpanzees into men. He asserted that “marked psychical and sexual excitation” typically resulted, followed by a resurgence of memory, energy and “genital functions.” [pp. 186-7]

I am sure I have heard of experiments with ground up animal testes before, but I don't recall reading about whole chimp testes bit.

I guess there was little resembling ethics committees in those days.

A good reason to avoid diabetes...

Turns out that diabetic's foot ulcers, even those with antibiotic resistant staph infections, do well with maggot treatment. There's an unpleasant photo of the maggots in action on someone's foot at the linked article.

Adams confirms his philosopher of choice

Scott Adams has a funny post in which he explains that he has discovered he is a follower of Spinoza. His reaction on reading about him on Wikipedia:

Holy cow! My opinions match Spinoza’s perfectly. It turns out that being ignorant is almost exactly like being a well-read student of philosophy who can quote from the work of the masters. How lucky is that?

The rest of the post is fun too. He's quite a wit, although I have noticed that the topic of bestiality seems to appear with unwelcome frequency on his blog.

Womb fights

It's an unusual event for me to be agreeing with Alan Ramsey, but his take on Bill Heffernan's revived comments on Julia Gillard seem about right. (Of course, by the end of his article, Ramsey is off on a bit of Keating admiration, and my disapproval of this sets the world right again.)

Despite Bill's clumsy way of putting it (I suspect that about 75% of the problem was the use of the word "barren,") as an issue I still think it is pretty fascinating to watch the modern feminist reaction to this.

As I noted in an earlier post, Julia Gillard seems to have expressed an attitude of "you can't have it all" as her reason for not having children. Isn't this a pretty dramatic, and quite conservatively aligned, change of attitude from the school of feminism that insists that society needs to be arranged so that women can do family and work at once?

Even though she supports Julia, if I were a female politician with children, I certainly can't see that I would be treating Tracee Hutchison as an ally. Maybe you can read Gillard as simply meaning that no one can easily be a mother and federal politician. (In her quote linked at my previous post, she made the point that male politicians only manage because they leave the mother at home to look after the kids. But even that overlooks the fact that some female politicians do manage by having a stay at home father.) Maybe Julia's comments are limited to her own assessment of her own abilities? (Well, I don't think that is right, but I am just looking at all possible spin you can place on it). But Tracee takes the argument to a whole new level:

Gillard's supposition that she couldn't have done babies and politics simultaneously — and done justice to both — should be given the respectful consideration it deserves...

Do you know the people who'll be thinking most about your comments, Senator Heffernan? Women who don't have children, that's who.

Clearly the senator, and many like him, have never considered that women without children probably spend more time thinking about the consequences of choices and the dynamics of society than people who spend their lives flying around the country on parliamentary salaries or up to their elbows in nappy buckets and vomit.

Conversations about nappy buckets and birth choices do not a society make.

Ask a woman with kids how much she thinks family dominates the structure of her life and she'll tell you it occupies most of her waking hours, even if she's juggling a career around it. She won't have given much thought to it, mind you; it's just how it is and she hasn't got time for musing anyway.

Um, doesn't this seem to be saying that it is obvious that women with children have no time to think deeply about anything, apart from what to cook for dinner tonight? What are those mothers doing as politicians then?

One suspect's that Tracee's reaction may be based on her very personal reaction to how other women, and men, react to her as (I assume?) a childless woman:

...ask a woman without kids how often she feels like an outsider looking in on a world she can't connect with and she will have some real insight into the way society functions. Particularly the way it reflects the status of women...

Sounds to me like she has lost a friend or two after they've gone off and joined the world of motherhood. (I could be wrong, of course, and misreading her completely.)

Tracee also seems to hate the way parties like to support families:

Despite John Howard's and Peter Costello's attempts to distance themselves from their wayward senator's latest spray, they are the culprits of turning the family values mantra into political paydirt and their imminent budget sweeteners to families will reinforce it.

Forget about the clever country we once aspired to be, we've become the conception country.

Somehow, I don't the Labor campaign is going to keep her happy either.

The creepy side of Japan

Photos of preteen girls in thongs now big business | The Japan Times Online

What this article says is quite true - if you go to Akihabara in Tokyo, which most visitors do to look through the vast world of consumer electric goods - there are also stores selling magazines and DVDs which, by the cover, clearly are about underage girls in various states of undress.

That Japan tolerates this seems pretty remarkable. As the article indicates, it's not that it doesn't have child porn laws, it seems just to lack the will to enforce them.

Hitchens on Hitchens (and other stuff)

Go here for a short, half amusing, half serious, interview with Christopher H.

Labor knows how to recruit

Rudd's star recruit is raising eyebrows - Opinion - smh.com.au

A very funny opening to this SMH article:
LEADERSHIP, women and sport aren't often seen together. Sometimes when they are, the different worlds collide spectacularly. Take Nicole Cornes, the very blonde wife of Graham Cornes, a legendary South Australian AFL footballer. She remarked yesterday, after her awkward press conference announcing she would be the Labor candidate for the federal Liberal seat of Boothby had been splashed across the front page, that "first thing in the morning when you wake up, you think, oh God, I should have had my eyebrows waxed".
And if I can be allowed to be exceedingly shallow for a moment, has anyone else thought that Peter Garrett's face recently is looking more gaunt and, well, scarier than ever? Compare this photo with this one. (Actually, I don't know how recent the second one is, but if he doesn't smile, he looks pretty crook.)

A gift for pun writers

TV ban is hard cheese for dairymen-News-Politics-TimesOnline

Apparently, England has banned cheese advertisements from children's TV, because it is deemed to be high in fat and salt. (I thought it was also good for teeth and an important source of calcium, but there you go.)

Naturally, cheese makers are not happy:

A survey published in The Grocer magazine, of 100 senior people in the dairy industry, confirmed that the overwhelming view was that cheese is under siege.

Only 2 per cent believed that the Government was supportive of the cheese industry while 52 per cent said that it was actively “anticheese”.

What foods can they advertise on kid's TV, I wonder. Green salad? As a fan of cheese (in moderation) myself, I hope to see rioting in the streets of London over this, and the downfall of the government.

Issues with reproductive technology

There's an interesting article at Slate about a couple of new books on the problems with assisted reproduction (IVF and other techniques).

The main current problem: the number of embryos which are often implanted has lead to a large rise in the number of multiple births, which tend to be bad for everyone (mothers, children and society.) There are also higher rates in IVF children of other odd medical conditions, and no one yet understands why.

The situation in Australia is summarised in a fairly recent Medical Journal of Australia article. It would seem that maybe only 30% of women here try a single embryo implant, and the rest go for double embryo transfer. This is despite the very significant health risks of having twins.

(The Slate article indicates that in America, some clinics may offer to implant 3 or even 4 embryos, which is pretty crazy really.)

I love technology, but have old fashioned views when it comes to reproduction. I can't quite reconcile how a country like Australia can have both an abortion rate of perhaps 80,000 or so per year, and around 5,000 births through IVF. There are clearly thousands of healthy embryos going to waste, while at the same time a relatively small proportion of women are going through expensive, painful and potentially dangerous treatment to have a child that stands a higher rate of illness than a naturally conceived one.

One final, slightly off the wall, point to make. I hope people have not forgotten about the 2001 study which indicated a very strong positive relationship between third party prayers and the success of IVF.

I had wondered why such a startling result was not the subject of follow up studies. However, it seems that the paper was pursued hard by a group associated with the Skeptical Inquirer, who pointed out the generally fraudulent activities of one of the authors. The skeptics attack is explained here. It is worth noting that it is based on guilt by association, rather than establishing how any fraud may actually have been done. (The skeptic's report seems also wrong where it indicates that the Journal of Reproductive Medicine removed the report from its website. It still seems to be there now, as shown by my link above.)

The skeptics also get a bit silly, I think, when they say that the head doctor of the study:

...was investigated by the U.S. Department of Health and Human Services Office for Human Subject Protections, because the researchers never got informed consent from the patients in the trial. Such misconduct is a serious violation of medical ethics and federal rules that were adopted to prevent the kind of atrocities that occurred in Nazi Germany and in the United States during the infamous Tuskeegee Syphilis Study.

Oh come on. What they were studying was something that could only have positive results if successful. Unless skeptics think that there is a risk that God punishes those hopeful women who were being prayed for, this is a pretty trivial issue, isn't it?

I would like to know if anyone else is going to do a similar study, but Googling has not brought up any quick answer to that.

If it was confirmed, it would certainly indicate that, if nothing else, God seems to like babies.

A problem with Starbucks

Bryan Appleyard has an amusing post about irritating people who effectively set up office in Starbucks. (I like the punchline especially.) Can't say that I have ever witnessed this behaviour in Brisbane, but then I don't like Starbucks and rarely visit them.

As far as I can tell, most Australians think Starbucks coffee is not great. I am no great fan of the beverage, but I really like a medium size Very Vanilla Chiller from Gloria Jeans. The GJ franchise just seems a lot more relaxed and less pretentious than Starbucks, too.

Do black holes exist at all?

Could black holes be portals to other universes? - space - 27 April 2007 - New Scientist Space

I missed this last week. Seems that maybe it is hard to tell a black hole from a wormhole.

This is also relevant to the issue of micro black holes. As the article says:

And there might be a way to test the conjecture. Some physicists say that future particle accelerator experiments could produce microscopic black holes (see Atom smasher may give birth to 'Black Saturns').

Such tiny black holes would emit measurable amounts of Hawking radiation, proving that they are black holes rather than wormholes. But if Solodukhin is right, and microscopic wormholes are formed instead, no such radiation would be expected. "In that case, you would actually see if it is a black hole or a wormhole," he says.

An added benefit of wormholes is that they could resolve the so-called black hole information paradox.

Is there any safety significance to a micro wormhole being created at CERN instead of a micro black hole? I suspect not, but it would good to have someone who knows more than a blogger from Brisbane saying it.

Charming

I've complained before about the dire quality of Road to Surfdom since Tim Dunlop handed over the reigns to the likes of Ken L and Aussie Bob.

It's not that it's just anti-Howard; the name calling is offensive. Have a look at the description Aussie Bob gives to ABC newsreader Juanita Phillips in his recent comment here.

Oh yes, the Left is full of respect for women.

Dunlop himself in a post felt free to use c**t for humourous effect, and his commenters were happy to follow suit. JF Beck also had a post on his site recently showing the sophisticated level of debate that Ken L exhibits when challenged. (I might have had something to do with that...)

Anyway, my point is that it's a pathetic site that is only saved from criticism by the Left by being on the Left.

More than you ever needed to know about duck anatomy

In Ducks, War of the Sexes Plays Out in the Evolution of Genitalia - New York Times

Who knew that duck's had such strange genitalia:

Dr. Brennan, a post-doctoral researcher at Yale University and the University of Sheffield, visits the sanctuary every two weeks to measure the phalluses of six species of ducks.

When she first visited in January, the phalluses were the size of rice grains. Now many of them are growing rapidly. The champion phallus from this Meller’s duck is a long, spiraling tentacle. Some ducks grow phalluses as long as their entire body. In the fall, the genitalia will disappear, only to reappear next spring.

Not much chance of a duck hiding his interest during summer.

Mad scientist at work?

One of my ongoing duties to my embarrassingly small readership is to keep an eye on arxiv.org and report on papers that I don't understand but which still seem important, or at least entertaining.

My latest find is a topical one for Australia. The extremely prolific Russian-American scientist Alexander Bolokin has a recent paper with two novel approaches to extracting water from the air in large quantities. The paper itself, in far from perfect English, is here.

The two ideas:

1. A 3 to 5 km high (!) and 200 m wide inflatable tube is erected and supported by wire cables. Moist air is heated at the bottom, rises up through the tube (drawn up by the wind shear at the top of the open tube.) Moisture condenses at high altitude, is collected and on its way back down is used to generate electricity (through a turbine at the base, I think he means.) He also has a wind turbine at the top, although one expects that this may be rather heavy and not be good for the balance of a 3 km high inflatable tube. Solar cells on the outside of the tube get a mention too.

As I will explain below, Bolokin has a real fondness for high inflateable towers as potential tourist attractions, and this tower also has elevators and tourism built into the concept.

How much water does he think this will produce? About 224,000 Kilolitres a day. According to the Courier Mail, the south east region of Queensland was currently still using about 700 megalitres a day. So one tower does not do away with the need for rain entirely, but would make up a very reliable big percentage of daily use.

2. The second idea is to pump moist surface air through a tube beneath the sea to a depth of perhaps 30 m, where (so he says) the water temperature is 5 - 10 degrees. I assume water is then condensed out too, but the details of this method seem poorly explained compared to the big tower. Certainly, though, the engineering involved in getting air down to 30 m below sea level sound a lot less daunting than getting it up a tube 3 km high.

You can't accuse him of not thinking big, at least.

But is he making any sense at all?

One of his other recent ideas is for an inflatable space elevator filled with electron gas. His "electrostatic mast" would simply be built from the ground up, up to 36,000 km high or more. (Actually, he says that current strength materials would allow one to be built up to 500 km high; bigger ones require new material, I think.)

Bolokin notes that a feature of such a tower would be the "entertainment and observation platform", although he does not specify at what dizzying height this could be.

One other idea he mentions:

The airship from the thin film filled by an electron gas has 30% more lift force then conventional dirigible filled by helium. (2) Electron dirigible is significantly cheaper then same helium dirigible because the helium is very expensive gas. (3) One does not have problem with changing the lift force because no problem to add or to delete the electrons.

So, while he appears to have done sane enough work in past, has Bolokin jumped the shark with these ideas? Or is the future really inflatable?

Current movie dross

It's good to see Quentin Tarantino having a certified flop. His main oeuvre of ironic dark splatter fun has never appealed to me, and (dare I say it, because he does have his intelligent defenders) has always seemed to me to be the work of an immature man made primarily for immature men.

There are worse films around, though, and it always surprises me that the surge in misogynistic horror (including Australia's own recent entry - "Wolf Creek") has been attracting an audience, but little in the way of public outcry. The Guardian has a good article about this disturbing trend. You would have thought that even "third wave" feminists might have been more vocal about this, but it seems to attract very little attention, apart from the odd scathing review.

Even without the misogynistic element, I just don't get horror generally. Tension and scares are fine, enjoyable even, but a desire to see the blood and guts and body bits dismembered - what exactly is the appeal? Give me Hitchcock and a knife in the back any day over a realistic depiction of decapitation.

Reviewing the flat earth

It’s a mad old world-Arts & Entertainment-Books-History-TimesOnline

This looks like an interesting book, covering the history of the idea of the earth being flat. It was not as common an idea as some people seem to think:

....it’s really quite stupid and credulous of us now to believe that most medieval people thought Columbus would fall off the edge of the world. They could see as well as you or I that a ship disappears over the horizon after a few miles, or that during a lunar eclipse, the shadow of the earth on the moon is round. Duh. There was “no mutiny of flat-earth sailors on the Santa Maria”.

Plato, Aristotle, Euclid, Archimedes, Ptolemy, St Augustine and Bede were all firm “globularists”, in Garwood’s pleasing neologism, while Newton refined things still further by showing that we really lived on an “oblate spheroid” (the earth bulges in the middle, to you and me).

More on evidence of psychosis and marijuana

BBC NEWS | Health | Cannabis 'disrupts brain centre'

This report indicates that some very specific experiments with THC should really be putting the final nail in the coffin of the the arguments against there being cause and effect between marijuana use and schizophrenia.

Also, it notes that:

Experts are concerned that street cannabis is becoming increasingly potent. It is thought that average THC content has risen from 6% to 12% in recent years.

This increase in potency is highly disputed by some, but I presume "the experts" do have some proper basis for the claim.

An increase in THC sounds to me like a more plausible explanation for the danger of hydroponically grown marijuana, rather than it being due to the pesticides and other chemicals used while it is growing.

Japan, Sex and History

Japan's love affairs with sex | The Japan Times Online

This essay is not particularly well written, but contains enough semi-sordid educational material that it is worth reading.

For example, the founding myth of Japan has the first two deities as a husband and wife:

A charming account of their courtship follows, in which the god and goddess shyly discover each other's sexual parts and Izanagi declares:

"I wish to unite this source-place of my body to the source-place of thy body.''

Their first offspring were islands; then came a profusion of gods and goddesses, one of whom was Amaterasu, the sun goddess.

I wonder if that "source-place of my body" line works in bars in Japan today.

Hitchens' religion series

For those who haven't already noticed, Slate is running excerpts from Christopher Hitchen's new anti-religion book.

Of course, I don't agree with his thesis, but he at least promises to be a wittier and less irritating writer on the topic than the likes of Dawkins. (His preconceptions clearly influence even his literary judgement though; in the first extract he dismisses CS Lewis as a "dreary" apologist! Lewis may have flaws in some of his arguments, but a "dreary" writer he surely isn't.)

A couple of the extracts are already interesting: those summarising the foundation of Islam and Mormonism (and looking at the similarities between the two.)

Given our proximity in time to the founding of Mormonism, it is remarkable how that church is successful in light of the (relative) ease of investigation into the circumstances of its creation. (Of course, the Church of Scientology is an even more puzzling success.)

On the move in and out of Iraq

Comment is free: Iraq's refugee crisis

That there has been very large population displacement within and out of Iraq is clear. With such large population shifts, it's a wonder that there is not more regional multinational interest in helping end the turmoil. However, as the article notes:

Two million Iraqi refugees are scattered around the region, the great majority of them in Jordan and Syria, with smaller numbers in Turkey, Lebanon, and Egypt. Because they are urban refugees - not housed in tents, but rather blending in with the local population in the host countries - they are easily ignored.

I guess that the countries who are most interested in the internal situation in Iraq (I presume, Iran and Saudi Arabia) don't have many refugees and see it as not their problem.

The Tablet reports that things are not going well for the remaining Christians in Iraq either:

Archbishop Louis Sako of Kirkuk warned that attacks on Christians by radical Islamic groups, previously localised in sectors of cities such as Baghdad and Mosul, had now spread across the country, even into areas previously considered a safe haven for Christians.

"In Iraq Christians are dying, the Church is disappearing under continued persecution, threats and violence carried out by extremists who are leaving us no choice: conversion or exile," said the Chaldean archbishop.

Radical Sunni groups in areas of Baghdad were threatening local Christians with violence unless they paid a jizya, or "donation", towards the insurgency, immediately converted to Islam, or handed over their homes and fled the country, Archbishop Sako said...

Ten of Baghdad's 80 Christian churches have closed since 2003. Fifty thousand Iraqis are fleeing the country each month, according to the UN. While they make up 5 per cent of the population, Christians constitute 40 per cent of those fleeing.

Radical Sunnis are such a likeable bunch.

Update: Tigerhawk has a long and interesting post about a talk given by Lawrence Wright, who seems to know what he is talking about when it comes to al Qaeda. Good reading.

Just strange

BBC NEWS | Europe | Dutchman's Noah's ark opens doors:

A half-sized replica of the biblical Noah's Ark has been built by a Dutch man, complete with model animals.

Dutch creationist Johan Huibers built the ark as testament to his literal belief in the Bible.

The ark, in the town of Schagen, is 150 cubits long - half the length of Noah's - and three storeys high. A cubit was about 45cm (18in) long.

The ark opened its doors on Saturday, after almost two years' construction, most of it by Mr Huiber himself.

Al Gore should have been invited to the opening too.

Cranking up the insincerity

Rudd silent on economy, says PM. 27/04/2007. ABC News Online

Kevin Rudd has to resort to the patently silly forms of attack on conservative politics and the PM for the sound bites on TV tonight:

He says a Labor government would set a new standard.

"We stand for community, we stand for country, we stand for the planet," he said.

"By contrast, the conservatives stand for the three great ennobling values: me, myself and I."

Oh, bring me a bucket.

And as for Howard:

"Mr Howard doesn't really believe in a single idea which didn't appear on black and white television."

This is good in its own way. Resort to such platitudes, which we all know Rudd doesn't genuinely believe (he has the personal friendship with Joe Hockey to illustrate that,) means that he is should start to be seen as cranking up the insincerity for marketing purposes. He is thus shown to be just another politician, which may be the start of of a drop in his puzzling popularity.

Speaking of insincerity, Tony Jones on Lateline last night, interviewing a Kevin Rudd who seemed to me to be unusually giggly, missed a golden opportunity in this section:

KEVIN RUDD: ...... Mr Howard's not interested. We could reduce greenhouse gas emissions, I'm advised, by up to 30 per cent by affecting, by implementing, such an effective demand-side management approach. And lastly, what do we do about clean coal and what do we do about hybrid cars and those sorts of things? We've got clear cut policies on the table for the future. What do we get from Mr Howard? Resounding silence, because he's rooted in the past.

What you do, Kevin, if you really believe in them, is drive one yourself. (Not that Tony Jones made that rejoinder).

More Ehrenreich scepticism

Scotsman.com Living - Books - Party, party, party

This is a good sceptical review of Barbara Ehrenreich's book "Dancing in the Streets" that I mentioned a few posts ago.

Strange goings on in Italy

After a flurry of cases in the 1980's, things have been pretty quiet in Britain and the USA recently with regards to claims of satanic child abuse. However, it has made an appearance again in Italy:

Three women teachers were among six people arrested yesterday accused of sedating and sexually abusing children as young as 3 at a school near Rome.

The teachers — two of whom are grandmothers who had taught at the school and at Sunday school for decades — are said to have part in the repeated abuse of 15 children aged 3 and 5 for a year, filming them in sexual acts with satanic overtones at the teachers’ homes and in a wood.

Even the parish priest defends the accused:

Ottavio Coletta, the Mayor of Rignano Flaminio, said that the town of 8,000 people was enveloped in “a poisonous climate of hatred and vendetta”, and Father Erri Rocchi, the parish priest, said he still believed the teachers were the victims of “malicious tongues”. He said that the women were church-goers and taught at Sunday school.

Unless there is actual video evidence, the odds of eventual acquittal for the accused would have to be extremely high.

The ridiculously complicated games of Iraq

Despite his rhetoric, Sadr needs U.S. - for now - International Herald Tribune

This article explains the complications caused in Iraq by Moktada al-Sadr's ever changing (and often contradictory) actions in Iraq.

It seems extremely unfortunate that such a character has a stage on which to strut.

Meanwhile, it is disturbing to see what passes for sensible commentary on the increasingly deranged Road to Surfdom. Ken really feels for the citizens of Iraq (no issue there), but lets this wave of emotion lead him to say the following:
Yet millions of Australians and tens of millions of Americans, people of ordinary intelligence and goodwill, accept all this being done in their name with the complacent justification that the Iraqis are better off than they were under Saddam, or that the known tragedies associated with the occupation pale into insignificance compared to the tragedies that are predicted to accompany any withdrawal – even though the consequences of withdrawal are unknowable and the gates of hell forecasts are made by people who have a blatant vested interest in the occupation continuing.
So, what is more immoral? Leaving now, even against the wishes of a rabid anti-American like al-Sadr (see article above)? Or trying to assist in the prevention of the sectarian violence between civilians, which is clearly what most of the death is now about?

It is possible that an immediate withdrawal might mean that the country settles down in a shorter period, but in all likelihood only at the cost of a dramatic rise in death, displacement and mayhem first. (Who wouldn't expect a serious partition attempt if the US left right now, and who expects that it could be done without large loss of life?) It is quite ridiculous to suggest this view is only promoted by those with "vested interests" in America staying there.

What it comes down to is this: Ken prefers the idea of gambling with the lives of civilians, rather than see something in place that is specifically designed to help protect them. I don't see how you can seriously argue that staying there for now is not the moral thing to do.

UPDATE: a column in The Guardian also takes up the point of the complicated and often duplicitous actions of all the major Middle Eastern players in Iraq. It is well worth reading, but the general point is that many parties who claim to want the US out of there are just posturing. They actually want America to stay, at least for the time being.

Not everything said in this analysis might be accurate, but overall it sounds fairly plausible. It certainly indicates why, contrary to the normal expectation of Western democracy, the opinion of the people in Iraq on this is not something is deserving of enforcement at the moment.

UPDATE 2: Diogenes Lamp posts about a funny/serious letter to The Age about the silliness of comparing Iraq to the V-Tech killings.

War bride stories for ANZAC Day

The 7.30 Report - ABC

This year, the fate of Australian war brides has been getting a lot of attention. Last night's story on 7.30 Report (link above) was a pretty charming interview with a couple of WWII war brides from Australia who ended up in America. (The sprightly 90 year old was nicer than the other one, but she did remind me somehow of Barry Humphries in drag.) Go have a look at the video.

There's also a recent book out (Swing By Sailor) about 669 war brides who went to England in 1946 on a semi-converted British aircraft carrier. This Bulletin article summarises the story:

If any of the brides was apprehensive about what lay ahead, she tried not to show it when the ship left on July 3, 1946. It had cost £16,000 to convert the aircraft-carrier to house 700 women, crew and demobbed sailors, a total of 1854 on board. Berths and bathrooms replaced aircraft hangars; a soda fountain, cinema and even a hairdressing salon were installed. But, writes Dyson, Captain John Annesley "had no idea how unruly a warship of brides could be".

"One of the captain's first talks was about sex not rearing its ugly head on his ship," recalls Monk. Even before the ship had left the Heads, however, there was "carrying on", she says, hooting with laughter. "It was like a smorgasbord to some of the girls - so many lusty young men available."

Hey - I thought it was about going to be with your new spouses! Just goes to show that images of a prime and proper pre-1960's world of sexual behaviour are far from accurate. Also, it sounds like Sydney may have had somewhat of a gay reputation even then:
Edna Wroe met her husband Eddie Monk in front of a jukebox at Playland arcade on Pitt Street. He was blond, blue-eyed and in a tight-fitting sailor's uniform, she says, and "if I wasn't fending the girls off, it was the guys trying to pick him up".
But back to this sex voyage:
As the ship entered warmer climes and the women sunbathed on deck, forbidden liaisons multiplied so quickly that "chastity rounds" were instituted. Monk was one of a dozen women whose husbands were travelling with them. Finding a "nookie hole" proved difficult, she says, because everywhere "was already occupied. Our secret spot was in one of the gun turrets. Being a gunner, Eddie knew".
All this fun can its consequences, though:
Word got back to some of the waiting husbands of affairs between their wives-to-be and crew. Telegrams would arrive saying, "Don't come. You're not wanted". Those who received no letters from their husbands began to wonder if anyone would be there to meet them. Indeed, some Aussie war brides were left stranded; others slipped away with their newfound British sailor boyfriends.
I also heard on Radio National recently a repeat of a documentary about Japanese war brides in Australia. It was very good, but there appears to be no audio or transcript available. The culture shock of moving from Japan to, say, Canberra at that time (as I seem to recall one of them did) must have been enormous.

These are not stories of great hardship, compared to what goes on during war itself, but as social history related to war, it's all very interesting in its own right.

About happiness

It’s sad but Dionysian orgies ain’ t what they used to be--David Aaronovitch-TimesOnline

This is a pretty interesting article on the (apparent) state of unhappiness in Britain now. It also casts a sceptical eye over the recent book by Barbara Ehrenreich which proposes as follows:
It is Ehrenreich’s contention that one significant factor in modern depression has been the suppression, over time, of communal rituals and festivals. And, in particular, the suppression of those events in which human beings collectively gave themselves over to ecstasy.
While initially sounding plausible, there are reasons to be sceptical of this theory. For example, Aaronovitch writes:
If it were possible to apply Ehrenreich’s analysis to the here and now, we should expect to find that those countries most influenced by Calvinism would be the most depressed and unhappy. And what we find is the exact opposite.
One of the comments at the end of the article also notes:
Isn't happinness something that arises within the human heart which subsequently organises parties? The argument of the article is that you organise events in order to generate happinness. Have a party, get slightly hammered, and then you'll get more of a feel-good glow. Well, we've had more and more of that in our city centres over the last ten years and the result, apparently, is less joy.
Oddly, despite pointing out reasons to be sceptical, Aaronovitch still seems to end up thinking that more communal partying is part of the answer:
We need more revelries. We need less anti-fun Nimbyism and more bonfire nights, street parties, open-air samba classes, Olympic Gameses, London Marathons, local carnivals, park concerts, Demis Roussos and raves.
Raves! Surely 10 hours of "doof doof" music at deafening volume is only made enjoyable by the attendees being under the influence of powerful illicit chemicals. (Alcohol alone being inadequate to the task.) Then those who get through the night on ecstasy are likely to have a downer when they come off the drug. No, amateur fiddling with brain chemicals is not a likely path to increased communal happiness.

But before I leave Aaronovitch , I do like this reminder of the extremes of some past communal celebrations:
Today the casualty of a rave might come to in a lockup minus his dignity and his watch. When the Anatolian cult of Cybele came to Rome in the 2nd century BC, its wild celebrations were marked — at their height — by members of the priesthood cutting off their own testicles. You can imagine waking up in the morning, asking yourself whether last night’s revels had really happened, and then looking down.
They don't make clergy like they used to.

People like Andrew Norton know a lot more about happiness research than I do, and it is a mildly interesting topic. But it should never be taken very seriously. I suspect it's like quantum physics; the attempt at observing probably changes what you are looking at anyway.

Bad news for Pete

PM gains, but Rudd leads - National - theage.com.au

The Age reports:

People were asked to imagine Peter Costello was PM and then quizzed a second time on how they would vote. Labor's two-party lead rose to 61 to 39 per cent. Asked whether they would prefer Mr Rudd or Mr Costello as PM, an overwhelming 60 per cent preferred Mr Rudd, to 32 per cent for Mr Costello.

I have never really understood Costello's unpopularlity. He doesn't seem to me any more insincere than your average politician, and the media who spend time around him seem to think well enough of him. It's hard to criticise his job as treasurer. He's nowhere near as demeaning to others in his parliamentary performance as Keating was; in any event, Keating showed that nasty headkicking can have an appreciative audience.

So why is he still unpopular?

The household gas chamber

Lucy Siegle: How can I evict house mice? | Magazine | The Observer

From this story one can learn the PETA recommended way to kill a mouse in the house:
...Peta (People for the Ethical Treatment of Animals) recommends a mousetrap that actually kills the animal, and gave the Radar (Rodent Activated Detection and Riddance device) an award last year. This is allegedly the world's smartest mouse trap: when a mouse trips it, the doors close and a tiny canister releases carbon dioxide. In 10 seconds the mouse is out cold, in 60 it's dead. The device then sends an email to a pest controller - all 'without any toxins going into the environment', boasts Rentokil.
I am sorely tempted to wonder out loud if they are manufactured in Germany, but that would be cruel.

(And anyway, they appear to have been developed in England. Damn!)

UPDATE: It also occurs to me that having such a device in your house must provide one of the most peculiar pretences you could ever use to get out of a date or meeting you were not enjoying: (After checking at your e-mail on your mobile device): "oh, sorry, must rush home, the mousetrap has just emailed me that it has caught something."

Some China reading

A few weeks ago, I noted that there seemed to be some pretty compelling reasons to be pessimistic about China's economy. If there was something fundamentally flawed in what Friedman says, I would like to hear the explanation.

On the issue of potential political instability, there have been a few articles around this week of interest. First, this one (reprinted from the WSJ by the looks) paints a glum picture of the potential for reform:

Many in the West think that Chinese growth has created an independent middle class that will push for greater political freedom. But what exists in China, Mr. Mao argues, is not a traditional middle class but a class of parvenus, newcomers who work in the military, public administration, state enterprises or for firms ostensibly private but in fact Party-owned.

The Party picks up most of the tab for their mobile phones, restaurant bills, "study" trips abroad, imported luxury cars and lavish spending at Las Vegas casinos. And it can withdraw these advantages at any time. In March, China announced that it would introduce individual property rights for the parvenus (though not for the peasants). They will now be able to pass on to their children what they have acquired—another reason that they aren't likely to push for the democratization of the regime that secures their status.
Earlier in the article, it notes that the size of the middle class as follows:
...200 million of China's subjects, fortunate to work for an expanding global market, are increasingly enjoying a middle-class standard of living. The remaining one billion, however, are among the poorest and most exploited people in the world, lacking even minimal rights and public services.
The New Yorker, meanwhile, runs a lengthy article on a political prisoner. It's a pretty interesting read that covers a lot of Chinese modern history.

Finally, China continues in the tradition of nations founded as worker's paradises which have appalling workers' safety standards. Today's news is of a particularly gruesome accident:

At least 32 workers were killed and two injured today when they were buried in white-hot molten steel at a metal factory in North East China, officials said.

The mishap was triggered when a 30-tonne-capacity steel ladle sheared off from the blast furnace, spilling liquid metal onto the factory floor three metres below.

The molten steel engulfed an adjacent room where workers had gathered for a routine shift change, the State Work Safety Administration said.

An exam to remember

Indian teachers 'purify' students with cow urine - World - theage.com.au

Extract:

The Times of India reported yesterday that upper-caste headteacher Sharad Kaithade ordered the ritual after taking over from a lower-caste predecessor at a school in a remote village in the western state of Maharashtra earlier this month.

He told an upper-caste colleague to spray cow urine in a cleansing ceremony as the students were taking an examination, wetting their faces and their answer sheets, the newspaper said.

"She said you'll study well after getting purified," student Rajat Washnik was quoted as saying by the CNN-IBN news channel. Students said they felt humiliated.

Accidental deaths of WWII

The friendly fires of hell | Jerusalem Post

This article tells the tragic story of 7,000 odd concentration camp inmates accidentally killed in the very last days of World War II.

(As the article notes, it may have been the intention of the Nazis that they all drown anyway, but it is still somewhat embarrassing that it was the British attack that did the job.)

You can learn something new every day.

This article points out that President Bush has significantly higher support in polls amongst the under 30's than he does with those over 60.

They also support the Iraq war more strongly, and the same age group did the same even during much of the Vietnam war, apparently.

Very odd, is all I can say.

The uncertainties of psychiatry

NEJM -- Treatment of Bipolar Depression

This editorial from the New England Journal of Medicine talks about recent studies on the use of antidepressants for bipolar disorder (the manic/depressive illness). This is of some interest to me because I have recently been reading at work psychiatric reports on someone who was initially diagnosed with this.

It would appear that American psychiatrists don't like to give anti-depressants for it because they believe it increases the risk of manic episodes. Apparently, European psychs don't worry about this much, and a recent study seemingly backing them up. However, the editorial questions whether this is a valid conclusion from the study.

This strikes me as odd: that there are different schools of thought depending on which continent your psychiatrist works.

Given that bipolar and anti-depressants have both been around for a long time, I would have thought that such an issue would have been sorted out long ago.

Instead, you get the feeling that, to a large extent, psychiatric patients are treated by trial and error, with individual biases not necessarily supported by studies playing a significant role.

Everyone should keep their fingers crossed for their continuing mental health.

Hey you!

This has been one of those weeks when I think my posts are particularly entertaining or interesting. As usual, this means no one makes a comment, at all.

At other times, I make a quick post that I don't think particularly well done, and someone at the top of the blogging chain links to it and I get hundreds of "drop-ins" for a couple of days before going back to a normal 30 - 40 hits a day. (OK, that has only happened a few times.)

Blogging is a weird game. Good thing I amuse myself, I guess.

I wonder whether non-realistic understandings of the quantum world lend credence to the idea that the universe is a simulation running on someone else's (God's?) uber-computer? It only needs to "render" something when someone is looking at it.

While we are talking about English history..

The past was a stinker | Review | Guardian Unlimited Books

This book review of "Hubbub - Filth, Noise & Stench in England" was re-printed in the Sydney Morning Herald a couple of weeks ago. It sounds like an amusingly appalling read. An extract:

Cockayne has dug deep into the archives and come up with a hundred little snatches of story that show ordinary people bustling about their business and taking care not to step in something nasty. Mostly they don't succeed. The walls of domestic dwellings in the 17th century were routinely bulked out by shit shipped from "the necessary house" and quite likely to dissolve into a nasty goo when the rains came down. One authority noted that few homes outlasted the ground lease of 50 years or so, while one German visitor wondered out loud whether he should venture into the street during a violent storm in 1775 "lest the house should fall in, which is no rare occurrence in London". "Kennels", or drainage ditches, were mostly bunged up with everything from brassica stalks to dead babies, and it was a good idea to carry a stick in case there were any rampaging pigs about (market days got them especially jumpy).

Inside was not much better. In 1756 Harrop's Manchester Mercury advertised a book that claimed to get rid of all household vermin, including "adders, badgers, birds, catterpillers [sic], earwigs, fish, flies, foxes, frogs, gnats, Mice, otters, Pismires [ants], Pole-cats, Rabbits, Rats, Snakes, Scorpions, snails, spiders, Toads, Wasps, Weasels, ... Moles, Worms ... Buggs [sic], Lice, & Fleas &c".


Fish were "household vermin"? Maybe it means silverfish.

The Sydney Morning Herald Blogs: All Men Are Liars

Sam de Brito, whose blog at Fairfax I don't particularly care for, has at least done a service by warning youngsters off marijuana, at least if it is of the hydroponic kind.

I don't have time to go looking for evidence of this today, but is the explanation he gives (that hydroponic stuff is dangerous because it is usually covered in pesticides and fungicides) actually been tested? I have heard it before, and it seems to be widely believed in the smoking community. But has it been tested?

More explanation on why the media does not love K Rudd

Cut & paste: Heavy the media and risk a broken glass jaw, Mr Rudd | Opinion | The Australian

After Kevin Rudd's clumsy attempt at heavy-ing the media was revealed by Alan Ramsey a couple of weeks ago, it's remarkable that Rudd appears to have attempted it again. Laurie Oaks brought this to light in a question at Rudd's Press Club appearance yesterday. Funny how this was not mentioned in the highlights I saw on the evening news (and even The 7.30 Report) last night. Here's Oaks' question:

LAURIE Oakes: This morning the editor of the Sydney Sunday Telegraph, Neil Breen, appeared on radio in Melbourne to talk about what's become known as the false dawn affair, or sun-lies.

He said after the story appeared in his paper, "Mr Rudd just went bananas about it, he just went crazy ... The phone calls started from then and they went to the highest powers of News Limited. I ended up speaking with him at length on Tuesday and he was just indignant that we were totally wrong, this story was baseless, when we in fact knew it was right. And then as ... he demanded what sort of remedy he wanted from us (for) publishing this story, (it was clear) he was involved in this fake Anzac service."

He also says, "It was the heaviest situation I've been in, in my journalistic career."

That's why I ask you, is that true? Also, as we know, it's not the first time this sort of thing has happened, as Kerry-Anne Walsh here from The Sun-Herald can attest.

How do you explain or excuse this sort of thing? Do you really think you can heavy the media? And what are you going to do about the glass jaw?

Rudd does not exactly deny it in his wishy washy response.

Maybe too much information in this post...

Looks easy enough... but not for everyone - In Depth - theage.com.au

This article is all about pauresis, the inability to readily urinate in close proximity to others. Mostly suffered by men because of the open design of most public urinals.

I think most men would guess, from the number of guys who head to the stalls in a public toilet, that it is not an uncommon problem. Indeed, it's not that unusual to see men who leave the stall door while standing to pee. They just need that additional bit of privacy. The Age article notes that "...a 1975 study by two psychologists at the University of Idaho that found a quarter of the male college students they questioned reported difficulty "getting started" when using public urinals." At another point it says:

People acknowledging occasional problems with hesitancy include Oprah Winfrey, Andrew Denton and US shock jock Howard Stern. In fact, recent studies show that about 7per cent of the public may suffer from this social anxiety disorder to some extent.

As an intermittent mild sufferer of this myself (and yes, just as the article suggests, it was started by some taunting by some nasty older kid behind me in primary school,) I have never understood why the designers of public toilets in Australia (or most of the world) do not seem to pay any attention to this as an issue. For example, going back to my trips to Disneyland in the 1980's, I noticed how the toilets there had the individual urinal that is now common here, but with simple privacy screens attached to the wall between them. These just extended about 40 cm or so between each urinal, mid body, and meant that you just had that additional bit of privacy. It worked for me. I remember thinking at the time that it was nice to see that Disney understood the problem, as I think before that trip I had already read something about paruresis, and the screens seemed to be addressing that issue. (Now that I think about it, maybe it also had something to do with not wanting pedophiles to be able to "check out" boys, but I am not about to write to Disney to ask about their primary motive for this design!)

Ever since then, I have tended to notice whether public toilets have copied this, and I think I can say without fear of contradiction that it is extremely rare to find in Australia, even in toilets in new buildings.

This is an extremely simple and inexpensive feature to put in a new toilet being built, so why hasn't it caught on? If it would make up to , say, 20% of men feel more comfortable, isn't it worth it?

I note that the Age article features the story of a guy with paruresis so severe he can't even go in an aircraft toilet easily. Now that is severe, and I can't imagine why he didn't seek help about this before he was in his fifties.

On the Virginia Tech killings

Cho Seung-Hui's Plays - News Bloggers

Assuming they are genuine, it is pretty weird reading two short plays by a mass murderer that indicate he did indeed have serious mental issues of some description or other.

I am not sure how I feel about the rapid publishing of this material. It's ghoulishly interesting, but seems too soon after the event.

In cases like this, I can't help thinking about the killer's family and the burden of guilt or shame they presumably must feel. (This is assuming they are relatively normal family and have not mistreated the killer as a child in any dire fashion.) I don't mean to diminish the pain of victims' families, but at least the death of an innocent victim does not carry the same psychological burden of self assessment as that of being the "normal" parent of a mass murderer.

On the topic of gun control philosophy generally that this raises, there's a good discussion in progress at Catallaxy.

Toto to fix buttocks-scorching bidets | The Japan Times Online

Tipler on life in the universe

My favourite cosmologist Frank Tipler has a recent paper up on arxiv about intelligent life in the universe, and summarising the development of his end of universe theories first explained in length in The Physics of Immortality.

This one is under the arxiv section "popular physics" and is easier reading than some of his stuff. I guess I still have to work out what unitarity is, though, as it is rather crucial to his argument.

For the diminishing number of readers who have made it this far into this post: one of the things which gives me reservations about Tipler is his whole hearted endorsement of "many worlds" interpretation of quantum physics. Over at Quantum Quandaries there is a recent post arguing philosophically about "many worlds", and any post that deals with Kant and quantum physics is well worth reading, isn't it?

More on abortion in England

A crisis brought on by our selfish desires-Comment-Columnists-Libby Purves-TimesOnline

Libby Purves notes that in England they are having trouble finding enough young doctors willing to take on abortion training.

Her explanation of the law in England makes it sounds rather similar to ours, with its implementation effectively meaning abortion on demand.

I don't know why issues with abortion seem to be more actively discussed in that country than here.

The shorter Rudd

Just a quick comment: it seems that Kevin Rudd is in the odd position (at least for a Labor politician) of appearing to be much more unpopular with journalists than he is with the public.

How long can that go on?

How to end the drought

Despite meteorologists earlier this year giving us optimistic news about the end of the El Nino, Brisbane is extremely dry. Water supply dams are at about 20% capacity at the start of our dry winter season. We are meant to be in autumn, but this weekend, I saw that this week may have two days of 31 degrees. The hardware shop that I went to yesterday had sold out of greywater extension hoses, which everyone is buying to get washing machine water outside for the dying plants in their yards. One of my neighbours has lost several large palm trees, and I notice several others around the neighbourhood that are on their way out.

A lot of Australia is suffering, although it does seem that Brisbane has been in a particularly dry band this last year. Far North Queensland is fine; Sydney seems to have had many more days of rain than Brisbane.

Many people over the centuries have believed that drought is sent as a punishment from God. I don't think this is a very likely explanation, but then again there is the eerie co-incidence that Brisbane water supply has been on a downward trend ever since: THEY STARTED MAKING AUSTRALIAN BIG BROTHER HERE.

Have a look at the chart:



(There is a possible flaw in my theory in that it turns out, to my surprise, that BB has been going on since 2001. Maybe the first few seasons weren't as sleazy as those since 2004, when our combined dam levels just started sliding down the slope continuously.)

I find Big Brother the most teeth grindingly awful thing ever shown on television in my lifetime. If I were God, I would want to punish any city hosting it.

Yes, I say that to end the drought, thousands of people should go to Dreamworld and burn down the Big Brother house (just before the new series starts) on the basis that:

a. it would please God (or gods of any description), or
b. even if you don't believe such action will end the drought, it would be a service to humanity anyway, as well as making me very happy.

Get your torches ready, there is no downside to the plan as far as I can see.

(Note: apologies to Danny Katz for my borrowing his trademark use of capitalization for humorous effect. Although, in fact, this post was not meant to be entirely humourous.)

Nick Cohen on eco death threats

Guardian Unlimited | Comment is free | Beware the noxious fumes of eco-extremism

Nick is no skeptic of global warming, but still points out how nasty extremism does not help the environmentalists' cause. This point that he makes at the end is quite important:

The absence of visible improvements sets climate-change legislation apart from every other anti-pollution measure. The Clean Air Act of the Fifties ended London's smogs. If Londoners complained about not being able to burn coal in the new smokeless zones, their councillors could point to the incontrovertible fact that deadly peasoupers had gone...

The prohibitions tackling climate change will stand in stark contrast. They will hurt, but they won't produce observable results.

Really stretching the argument

Abortion: why it’s the ultimate motherly act-Comment-Columnists-Caitlin Moran-TimesOnline

This column from last week in The Times really stretches one part of the pro-choice argument 'til it's micron thin:

....what I do believe to be sacred — and, indeed, more useful to the earth as a whole — is trying to ensure that there are as few unbalanced, destructive people as possible. By whatever rationale you use, ending a pregnancy 12 weeks into gestation is incalculably more moral than bringing an unwanted child into this world. Or a child that, through no fault of its own, would be the destructor of a marriage, a family, a parent. It’s fairly inarguable to say that unhappy children, who then grew into very angry adults, have caused the great majority of mankind’s miseries. If psychoanalysis has, somewhat brutally, laid the responsibility for mental disorders at parents’ doors, the least we can do is to tip our hats to women aware enough not to create those troubled people in the first place.

This paragraph leaves open so many obvious lines of attack, I can't even be bothered starting.

The author is (somewhat like Aussie blogger Audrey ) also taking the line that women should admit that having an abortion is often an easy decision. Moran writes:

Last year I had an abortion, and I can honestly say it was one of the least difficult decisions of my life. I’m not being flippant when I say it took me longer to decide what work-tops to have in the kitchen than whether I was prepared to spend the rest of my life being responsible for a further human being. I knew I would see my existing two daughters less, my husband less, my career would be hamstrung and, most importantly of all, I was just too tired to do it all again.

I don't mind this admission, because I think most pro-life-ish people like me have always guessed or known from experience that it was true for a significant number of women. The "women never take the decision lightly" line is, I think, deployed as a tactic designed to stop detailed debate, particularly if it is a man with whom the argument is being conducted.

[Of course, the pro-life movement also uses the "women always suffer" line to its own ends, by (I think) inflating the problem of depression or other medical conditions following abortion.]

The point is that the mere question of how difficult a moral decision was (or wasn't) for some people is never really the answer to the question of whether it was the right decision.

American toilet humour



A couple of comments about this ad. First, wouldn't it be better to have the guy single and desperate, rather than having his (presumed) girlfriend or wife turn up at the end? (If it was in an apartment building, wouldn't it have been funnier to have the plumber herself seeing him doing this?)

Secondly, is there some issue about Americans needing stronger flushing power than the rest of the world? It just seems a bit of an odd feature to be promoting in a toilet.

The "incivility" problem

Guardian Unlimited | Comment is free | You're rude, crude and in my face - and I've had enough

This is a pretty good essay on the problem of "incivility" in society in Britain, with obvious relevance to Australia and other Western nations too. (Indeed, I have read articles from Japan in which the the impoliteness of youngsters in public is discussed.)

This always seems to be one of those problems that everyone can identify, but no one really comes with convincing ways to address.

Send in the battle dolphins

LiveScience.com - Navy Shows Off Its Terror-Fighting Dolphins

This US Navy work with dolphins doesn't get much publicity, but is going to be around for a few years yet, it seems. From the article:

...the Navy announced plans to send up to 30 dolphins and sea lions to patrol the waters of Washington state's Naval Base Kitsap-Bangor, which is home to nuclear submarines, ships and laboratories.

Both species can find mines and spot swimmers in murky waters. Working in unison, the dolphins can drop a flashing light near a mine or a swimmer. The sea lions carry in their mouths a cable and a handcuff-like device that clamps onto a terrorist's leg. Sailors can then use the cable to reel in the terrorist.

So that's what a croc eating an arm looks like

A vet’s helping hand is saved by surgeons-News-World-Asia-TimesOnline

I'm sure I won't be the only person linking to this story, but it is an arresting photo.

Out of depth

catallaxy - Those were the days - when Robert Manne had views on economics

This post over at Catallaxy is well worth reading. It's handy to be reminded of who used to say what about economics in the 1980's, and how wrong they turned out to be.

Another entry into the TV wars...

Sony aims to take lead in organic flat-screen TVs:
"We are going to mass produce and start selling eleven-inch organic electroluminescence (television) models by the end of the year, which will be a world first," said Sony spokesman Chisato Kitsukawa.
That's not a big screen, but this type of display is apparently bright and great to look at. They also use less power than an LCD screen, and are very thin. Look at these prototype ones:

Very cool, hey? (OK, just send me the cheque now, Sony.)

One for Tim Blair

Total destruction of forests predicted to cool Earth - Modelling study no excuse for deforestation, researchers warn.

I think I have read something like this before, but news@nature is running this story:
Large-scale deforestation — long fingered as a contributing factor in climate change — could cool Earth, say the researchers behind one of the first attempts to model the phenomenon at a global scale.

Logging is often attacked because living trees help to mop up carbon dioxide, thereby buffering rises in greenhouse gases. But deforestation has different effects in different parts of the world.

In high latitudes, for example, removing the forests could help to cool these regions. This is because the trees, which absorb sunlight, would be replaced by snow-covered fields in winter that reflect the light. But in tropical regions, cutting back on forests would mean that less water is transferred from soils into the atmosphere, meaning fewer clouds and a warmer planet.

Ken Caldeira of the Carnegie Institution of Washington in Stanford, California, and his colleagues have now compared these two effects and declared that the effect of boreal deforestation dominates. Removing all the forests would put a slight brake on global warming, they predict — enough to leave the world 0.3 °C cooler in 2100, they report..
Woodchipping for global warming - that should be Labor's new forestry policy.

Black hole science - interpretation needed

Regular readers know that I scan papers appearing on arxiv about black holes. They are often not easy to understand, to say the least. In fact, I half suspect that even other scientists outside of very narrow fields may find it an effort to follow most papers too. Here's a couple of recent examples:

The existence of closed timelike curves (CTCs) presents a clear violation of causality. In some cases these CTCs can be disregarded because to have them one ought to have an external force acting along the whole CTC, process that will consume a great amount of energy. The energy needed to travel a CTC in Godel universe is computed in [1]. For geodesics this is not the case since the external force is null, therefore the considerations of energy does not apply in this case and we have a bigger problem of breakdown of causality.

Following so far? Well, no, nor am I, but it sort of sounds significant, doesn't it? This was just the introduction to the paper, which actually found this:

In the present work we study the existence and stability under linear perturbation of CTCs in the spacetime associated to slowly rotating black hole (BH) pierced by a spinning string. We find that presence of the black hole makes possible to transform the CTCs present in the spinning string metric alone that are stable into CTGs. We also find sufficient conditions to have stable CTGs. This conditions are not very restrictive and can be easily fulfilled.

So, I gather that they think they have found a way that something which violates causality can be made around a black hole. If you are looking for some actual interpretation of what this means in real life, in language anyone can understand, it ain't in the paper.

Here's another obscure paper that may, or may not, be significant.

A new theorem for black holes is established. The mass of a black hole depends on where the observer is. The horizon mass theorem states that for all black holes: neutral, charged or rotating, the horizon mass is always twice the irreducible mass observed at infinity. The
horizon mass theorem is crucial for understanding the occurrence of Hawking radiation. Without black hole radiation, the Second Law of Thermodynamics is lost.

I have no idea what they are talking about, but in the paper, the authors use an exclamation mark, which means it must be significant (I think):

In each case, we found that the horizon mass is always twice the irreducible mass observed at infinity. The conclusion is surprising. The electrostatic energy and the rotational energy of a general black hole are all external quantities. They are absent inside the black hole!

This is also said to be relevant to Hawking Radiation, a matter of continuing interest due to the heavy reliance on it by the CERN people in figuring out what micro black holes will do.

By the way, the engineers and scientists at CERN made a mistake that recently caused a bit of a bang:

A £2 billion project to answer some of the biggest mysteries of the universe has been delayed by months after scientists building it made basic errors in their mathematical calculations.

The mistakes led to an explosion deep in the tunnel at the Cern particle accelerator complex near Geneva in Switzerland. It lifted a 20-ton magnet off its mountings, filling a tunnel with helium gas and forcing an evacuation.

Let's hope they do their work on what happens to micro black holes a bit more carefully.

More on Japan's odd creation myths

New look for Japan's oldest book | The Japan Times Online

A couple of weeks ago, I was surprised to read that old Japanese Shinto myths had a god molded from feces. Well, Shinto creation myths didn't end there. From the article above:

"The birth of Japan. The gods give us a story of love and violence." Thus is introduced this Japanese-language manga-illustrated edition of the "Kojiki" (Record of Ancient Matters) dating from 712 and Japan's oldest book. The publication is intended for primary-school children...

For some foreign readers, perhaps unable to read Japanese, the major interest will lie in observing the considerable violence with which the conventions of eighth-century Japanese narrative collide with those of our 21st century.

The text has been edited by a Yokohama National University professor and made more suitable than it actually is. The original has the very first woman, Izanami, burning her genitals when she gives birth to the fire god. Later, various gods are born from her vomit, feces and urine. Her own child, Susano'o, defecates in the sacred hall of his sister Amaterasu and then strews the feces about.

None of this is illustratable, even by the standards of modern manga, and so the celebrated result of such misbehavior -- the retreat of Amaterasu into her cave -- remains largely unmotivated.

And you thought Eve being made from Adam's rib was odd.

Libby takes on the bishops

Religion: it makes bishops go bonkers-Libby Purves-TimesOnline

I don't read much by Libby Purveson, so I can't recall where her politics generally lie. However this article, criticising the couple of English bishops who thought it was nice of Pres Ahmadinejad to mention religion when he released his captives, seems pretty accurate:

The cynicism of the Iranian leader’s lip-service to Easter and forgiveness should not need underlining. When Bishop Burns says they “put their faith into action to resolve the situation”, he ignores the fact that Iran caused the damn situation.

Cyclists limp home (yuk yuk yuk)

The cyclist's tight spot - Los Angeles Times

For all you ever wanted to know about cycling and sexual problems, read this article.

Actually, it indicates that it doesn't exactly affect a huge number of cyclists, but at perhaps 5%, it does seem a bit of a risk.

Here's some odd extracts from the story:

Because road cyclists lean forward on their bikes for better aerodynamic efficiency, Minkow later added a cutout in the nose of the saddle to relieve pressure on the perineum in this position. He is currently working on a design to help male triathletes, who pedal in an extreme forward aerodynamic lean. In that position, "you're riding on your penis," Minkow says...

In a study of 17 riders published in 2005 in the Journal of Sexual Medicine, researchers at the Boston University School of Medicine found that straddling a bike seat with a nose significantly reduced blood velocity in the arteries to the penis by more than 95%, but that sitting on a "two cheek" noseless saddle had virtually no adverse effect....

To this day, Goldstein says bicycles should come with a warning label, similar to those on cigarette packs, that cycling may cause impotence.

Well, just as long as they don't start adding photos to the warning like they do for cigarettes.

Money for time travelling

Physicist needs $20,000 for time-travel experiment

As far as I can tell, the explanation in the article of the science behind this proposed experiment is sound enough, but I am surprised that it hasn't been done before.
