Stupidest history idea (and we're off to see the Wizard)

PM leaving history students stranded in the past - Opinion - theage.com.au

Les Terry (apparently, the current "Chair of Australian studies at Tokyo University") writing in the Age this morning has the usual moan of academics about the Howard government trying to impose a conservative agenda on the teaching of history:

As with the referendum for the republic in 1999, the agenda has been firmly established to achieve the desired result of returning the nation to an imaginary glorious past, a time when facts and stories about great men ruled the land.... Taken together, these initiatives represent the Federal Government's intention to impose on the country an old-style nationalist program.... It seems that John Howard and some of his ministers are intent on translating their own personal values, rather than the broad policies on which they were elected, into policy prescriptions.

Blah, blah, blah, we've heard it all before. (And anyway, what did that last sentence even mean?)

But the stupidest suggestion was this:

The historians' manifesto from today's summit should resist making history compulsory, and instead demand that the Federal Government initiate projects of national significance, such as a national online database that contains model curriculums and teaching materials for teachers to draw on. Imagine being able to beam historical characters in their virtual form into the classroom and interview them about their lives and the times in which they lived? Who knows, it might be possible for students of the future to even download a virtual John Howard and ask him why he was so opposed to the new Australian republic in which they now proudly reside.

What?? Our Les might have been spending too much time in hi tech loving Japan. Unless he thinks that the future holographic John Howard will actually have the PM's mind uploaded into it, can you imagine a better method for disguising an interpretation of history as actual source material? Or does he propose the virtual PM only using the PM's words? If so, why not just watch the video of the real PM saying it?

Looking at dramatic historical stories may be a way of kicking off an interest in a period, and should always be accompanied by an analysis of any historical errors or inadequacies. That's about the natural limit of the use of dramatisations in teaching history.

But wait: here's an idea, if you want silly use of technology. When the Republican referendum was on, there was a lot of discussion of who would be "Head of State." My idea: it should be, literally, a giant holographic head, floating in the sky above Parliament House, something like the Wizard of Oz on a bigger scale. (See my profile drawing to get an idea of how it would look.) The facial features could one of those computer blends of photos, as submitted by any Australian citizens who wanted to literally be part of the Head of State.

How would the Head decide important matters? Well, let's face it, in the Australian system, the Governor General and/or Queen only make really important decisions maybe once or twice a century. I think a random number generator, or a Wise Governance algorithms programmed by Google would be all that is really needed. Otherwise, the Head of State could just float in the sky, looking wise and reassuring.

Blogger confusion

That was confusing. My blogger account seemed to change to a beta version or something (without my asking) and it forgot my password. Requests for emails to make sure I was using correct password did not arrive either. Finally a way around this was found. Normal blogging may resume soon, I hope.

For future reference

Stephen Morris: It is Islamic fascism | Opinion | The Australian

Tim Blair has already recommended it, but this piece in the Australian was really good, and I mention it here so I can more easily find it myself in future.

By the way, I was reminded today (by Keith Suter on the radio) of one really important point against the involvement of the US military in action against Iran: with 100,000 or so troops still there for the foreseeable future, it would be extremely dangerous to attack Iran and risk a Shia uprising against the US military presence in Iraq. Given that the recent London arrests (and Israel not having the best result out its Hezbollah war) has given an increased sense of inevitability about a military confrontation of Iran, this is an important point to remember.

Slow progress on the robot front

Stone: Japan's Love Affair with Androids - Newsweek Brad Stone - MSNBC.com

Who would have thought, say, 50 years ago, that making more life-like robots would be so difficult. (Well, let's assume the person in 1956 at least liked science or science fiction and thought about this from time to time.)

Young men don't read this

Libido lags for ladies in luck | Health | The Australian

From the above article:

THE female sex drive starts sputtering to a halt as soon as a woman has got her man, according to a new study.

Researchers have found that women's libido plummets so rapidly when they believe they are in a secure relationship that after just four years the proportion of 30-year-old women wanting regular sex falls below 50 percent.

There are few things that appear able to keep a woman sexually interested, the study found, but living apart for extended periods can help.

(But - surely living apart for extended periods must also run a much increased risk of infidelity, which tends not to help the sex life back at home.)

Back to the story:

The findings for women contrast with those for men, whose sexual appetite hardly flagged at all up to 40 years after marriage.

"Male motivation remains constant regardless of the duration of the partnership." Dr Klusmann questioned more than 500 people about their sex lives in order to measure changes in their libido.

He found that within a year of a relationship starting, female libido moved into steep decline.

While 60 per cent of 30-year-old women reported wanting sex "often" at the start of a relationship, the figure fell to below 50per cent within four years and to about 20 per cent after 20 years.

Today's fantasy article from The Age

Israel must forge new relationship with neighbours - Opinion - theage.com.au

Amin Saikal in the Age thinks that Israel will have to get used to not being able to win every war within six days now. (He doesn't mention that this is because the enemy this time is acting completely outside of the laws of war by taking shelter in civilian communities.)

Amin says this:

If Israel wants to have a peaceful, secure and normal life in the region, its leadership should seize on the UN resolution to engage in bridge building with its neighbours. As a central component of this it must address urgently the Palestinian problem on the basis of the internationally backed two-state solution.

While Egypt, Jordan and the Palestine Liberation Organisation have already made peace with and recognised Israel, the remaining Arab countries offered Israel full recognition in 2002 in return for such a development. A comprehensive peace would also delegitimise the causes on which such groups as Hezbollah and Hamas have drawn to justify their violent actions.

This is a bit rich, isn't it? The solution to the "Palestinian problem" according to Hamas, Hezbollah, Iran and Syria is to drive the Jews into the sea. How exactly does he propose that Israel "build bridges" with those entities that make it clear that they never intend recognizing Israel at all. (And whose populations are brain washed by government consent into believing that Jews are the source of all evil?)

The process by which Egypt and Jordan made their peace with Israel is surely completely different by the dynamic in the Middle East at the moment.

All a worry

Ideals become casualties of war - Paul Sheehan - Opinion - smh.com.au

Paul Sheehan definitely stirs the pot today about Muslim immigration, especially in Sydney.

For a Brisbane person, who only reads about the rape trials and the Cronulla riots in Sydney, it is hard to know what to make of this. I guess whenever any migrant group starts to settle mainly in one suburb or area, the old time residents resent it and can feel uncomfortable. However, Sheehan paints a picture of aggressive action by the new Muslim residents to scare out the old timers (or the permissive young).

It must be a difficult to report on, as it is obviously open to cheap tabloid sensationalism, as well as possibly attracting anti-vilification action in some jurisdictions. It's probably the sort of thing that is best understood (as Sheehand indicates) by knowing many local residents, which those outside of Sydney don't have much hope of doing.

The economic woes of Iran

Guardian Unlimited | Guardian daily comment | Nuclear row boosts 'failing' Iranian president

This Guardian report paints a very gloomy picture of the Iranian economy:

The economy is coming under increasing public scrutiny despite official controls on newspapers and restricted access to the internet. An estimated 80% of all economic activity is under direct government control or managed through cooperatives known as bonyads, often dominated by well-connected clerics. In contrast, 80% of the population works in the private sector.

Critics say US sanctions, which have discouraged foreign investment and technology transfers, cannot be wholly blamed for Iran's economic backwardness. There are also complaints that taxpayers' money allegedly being sent to Hizbullah in Lebanon would be better spent at home.

Particular concern is focusing on oil-rich Iran's lack of refining capacity. It has a petrol shortfall of 30m litres a day, which is made up by expensive imports. Critics also note its failure to keep up with IT and e-commerce developments. A recent UN report ranked Iran 98th in the world in e-government.

This part also surprised me:

Ali, a graduate in part-time employment, said it was very difficult for young people to find good jobs in a country where two-thirds of the 70 million population are under 30.

Of course I knew that all Muslim populations are increasing rapidly (especially compared to the West), but that population ratio still seems extraordinarily high.

I still don't really understand why Muslim populations, even those now in Western nations, want to procreate at such a rapid rate. According to this Guardian article (which is a fun read because of its general disucssion of Islamic views on specific sexual activities) there is no general prohibition on contraception.

Increased wealth and material comfort makes people want fewer children. But can it be that Muslim populations in Western countries having sighificantly higer unemployment rates leads them to having more kids? Seems there must be more to it than that.

Some more serious news from the BBC

BBC NEWS | UK | 'Plot to blow up planes' foiled

Of course, the big terrorism news is about the sudden escalation in airport security in Britain.

No carry on baggage at all. Nothing in your pockets. All carry on bags to go in with checked baggage.

This would be enormously inconvenient for people with bottles of alcohol or fragile gifts in carry on bags. (I recently, somewhat foolishly, flew with a bottle of alcohol in a checked in suitcase. It did not survive, but to my surprise, Campari does not stain clothes. By the way, it's my wife's drink.)

My second thought is: just how confident would you feel that there is not a bomb in the checked in baggage. Presumably there is much less chance of an explosion in the hold causing the plane to go down, but it's not something you want to be on board to test.

Even rats are more useful than cats

Gambian rodents risk death for bananas - World - www.theage.com.au

OK this is not a new story. The link above is an article a year old about how mine clearance rats were being trained in Africa.

The reason for the post is that on the BBC news site there is currently a video showing the mine clearing rats in action. (I can't link directly to the video window, it seems, so you just have to look for it on the video link.)

Have a look at the size of the rats. They are huge! Still sort of cute, although I guess at some size that adjective becomes inappropriate.

Some good news for Howard

Howard hails falling jobless figures. 10/08/2006. ABC News Online

The PM's comments on this seem apt:

The July job figures have surged beyond analysts expectations with the creation of 50,700 jobs in the month, well ahead of forecasts of just 7,500.

It has taken the seasonally adjusted unemployment rate down a notch to 4.8 per cent.

The rise in employment was almost equally shared between full-time and part-time jobs, while the participation rate - or number of people looking for work - also increased....

He [PM Howard] says it would be premature to say the laws are responsible for the extra jobs but the figure is enough to disprove claims that jobs would be lost.

"It is not however too early to refute completely, on the basis of these figures, the outrageous claims that were made by the Labor Party at the time, and by the unions at the time, that this new legislation would lead to mass sackings," he said.

About Muslims in Western countries

Guardian Unlimited | Comment is free | What young British Muslims say can be shocking - some of it is also true

This article suggests that maybe Muslims have a point in their complaint about some aspects of Western society (in this case, British society in particular):

Particularly among younger Brits in urban areas, which is where most British Muslims live, we drink more alcohol faster, sleep around more, live less in long-lasting, two-parent families, and worship less, than almost anyone in the world. It's clear from what young British Muslims themselves say that part of their reaction is against this kind of secular, hedonistic, anomic lifestyle. If women are reduced to sex-objects, young Muslim women say, I would rather cover up. Theirs is almost a kind of conservative feminism. Certainly, it's a socially conservative critique of some aspects of British society, particularly visible in their generation, in the urban neighbourhoods where they live.

And the critique is nuanced. Half those asked for the Channel 4 programme thought Muslim girls should make up their own minds whether to wear the hijab to school. Nearly a third of female respondents felt there was some truth in the idea that Islam treats women as second-class citizens. (The men just couldn't see it. Now I wonder why ... ) And a majority said that British society treats women with respect.....

The idea that these young British Muslims might actually be putting their fingers on some things that are wrong with our modern, progressive, liberal, secular society; the idea that rational persons might freely choose to live in a different, outwardly more restricted way; these hardly feature in everyday progressive discourse. But they should.

A fair enough point really, although of course one has to be careful not to let this argument turn into an excuse for militancy and murder within a society which (after all) they themselves chose to move to.

The ironic thing is that commentators who most vigourously promote understanding of the Muslim perspective are usually of the Western Left, which (at least in its current form) is the side most likely to promote the social issues like gay rights and laissez faire feminism which would most offend the conservative Muslims.

It may be difficult for conservative parties to make political mileage out of it (because they don't want to be seen as bending to a Muslim agenda), but there is an argument that voting conservative in Western countries is more likely to lead to less alienated Muslims within that country.

(OK - maybe that doesn't work in the US, because Republicans went into Iraq and are currently identified more closely with Israel than under the Democrats. And in Australia and Britain, conservative parties are not so socially conservative anymore. At least some of them draw a line at gay marriage, I suppose, and take a more pragmatic view of feminism. The difference is perhaps only marginal, but I still think it has some validity.)

Member for silly stunts

From stately sentiments to bird-brained burlesque | Matt Price | The Australian

Matt Price does not think highly of a silly stunt by Labor MPs in Parliament yesterday:

Yesterday, though, the mischief turned downright moronic. When Costello rose during question time, a bright-orange fluffy toy bird magically appeared on the desk of Labor MP Bernie Ripoll. You'll never ever be able to guess what it was. Starts with C? Ends with "icken"?

While most Labor MPs thought it all brilliantly funny, several cringed in undisguised embarrassment. Only the day before, Ripoll was recorded in Hansard accusing Alexander Downer of being an "evil little shit" so I guess we're lucky he didn't turn up waving a giant fluffy brown turd.

Speaker David Hawker was furious, and in the ensuing mayhem Ripoll and frontbench colleague Gavan O'Connor were both ejected. O'Connor feigned kissing the toy, then performed a lame chicken jig exiting the chamber. Hilarious, non?

While we are on this topic, some readers would have noticed the large billboards around town showing Kim Beazley literally tearing in half a mock up "Workplace Relations Act". ("Kim Beazley will repeal the unfair workplace relations law" goes the caption, or words to that effect.) It looks so (for want of a better word) "stagey" that I find it rather silly. I can't be the only one who thinks this.

I also think I may never have gotten around to complaining about the annoying way they were obviously told that whenever they mention the Workplace Relations Act, they all must use the identical phrase (what was it - "this extreme Workplace Relations law" ?)

Made them all sound like PR automatons rather than people who could come up with their own rhetoric.

Low marks for whoever is doing their PR advice, I reckon.

Japanese work

Western values 'are causing mental illness' - World - Times Online

From the short article above:

Statistics indicate that 60 per cent of workers suffer from “high anxiety” and that 65 per cent of companies report soaring levels of mental illness.

Meanwhile, the size of the Japanese population is shrinking, and for the first time the Government has acknowledged that the falling birth rate is linked to job-related factors. Directors of the Japanese Mental Health Institute blame the same factors for rising levels of depression among workers and the country’s suicide rate, which remains the highest among rich nations.

Merit-based pay and promotion are of particular concern because they are at odds with the traditional system, built on seniority, that has reigned supreme in corporate Japan. In the harsh new atmosphere of cut-throat rivalry between workers, the Institute for Population and Social Security argues, young people do not feel financially stable enough to start families.

I can think of some other reasons why workers may be depressed (based on some personal observations):

* a common expectation that anyone who wants to get ahead will work a 10 to 12 hour day, and then socialise after hours as well;

* an inability of most workers to have any more than a week's holiday per year (although they do get quite a few public holidays as well). Of course, some men who want to get ahead will take no holidays (apart from public holidays) for decades at a time;

* a traditional culture that is still inclined to view mental illness as a character failing or weakness. (A friend who works in Japan, supervising english teachers from all over the world, tells me that he has had calls from the police saying to come get a teacher who is in trouble before the teacher is sent into a psychiatric care. Apparently, everyone knows that if you are committed to a psych ward in Japan, it may be a very long time indeed before you are ever seen again.) The young are more open to seeking psychiatric help, I think, but the effect of this old cultural view is still strong.

Beware of the fish tapeworm

Tale of the Tapeworm (Squeamish Readers Stop Here) - New York Times

Fish tapeworm can make you sick (and it is hard to diagnose). I wonder if there are any Australian cases?

To boldly go where no cockroach has gone before

news @ nature.com-Space hotel gets a check-up - Inflated craft is holding up, but fate of guests remains uncertain.

This is funny: the small prototype inflatable space hotel has got cockroaches already:

The cockroaches were last seen alive on 16 June, when they were loaded in mesh-covered boxes into the craft. They were left in captivity, dining on water and dried dog kibble, until the delayed launch on 12 July subjected them to vibrations and acceleration. They were then in a vacuum for a few minutes before the Genesis I craft was deployed and inflated.

That would be enough to kill many creatures, but not necessarily the hardy cockroach, which can survive many weeks without food. Charles Cockell, now a professor at the Planetary and Space Sciences Research Institute of Open University, UK, once studied how well cockroaches can withstand a drop in atmospheric pressure. At 100 millibars — one-tenth of normal atmospheric pressure - the bugs actively pumped air into their abdomens to survive, he found, swelling themselves up in the process to about one and a half times the normal size. "It's pretty gross actually," says Cockell.

Bigelow Aerospace tested a number of different cockroaches and found that the Madagascar hissing roach, which can grow to more than 7.5 centimetres long and can weigh as much as 24 grams, proved that they had the right stuff by enduring more than 2 hours in a vacuum. "After 20 to 30 minutes they came back to life and we thought 'Oh my gosh, they deserve to go to space'," says Bigelow.

Let's hope that space radiation doesn't turn them into super mutuant cockroaches who return to earth to create havoc. (I like to consider all possibilities.)

Pump in the gas

ScienceDaily: Deep-sea Sediments Could Safely Store Man-made Carbon Dioxide

Some optimistic researchers say that pumping CO2 into deep ocean sediments could be the way to go:

Schrag and his colleagues say an ideal storage method could be the injection of carbon dioxide into ocean sediments hundreds of meters thick. The combination of low temperature and high pressure at ocean depths of 3,000 meters turns carbon dioxide into a liquid denser than the surrounding water, removing the possibility of escape and ensuring virtually permanent storage.

Injecting carbon dioxide into seafloor sediments rather than squirting it directly into the ocean traps the gas, minimizing damage to marine life while ensuring that the gas will not eventually escape to the atmosphere via the mixing action of ocean currents. At sufficiently extreme deep-sea temperatures and pressures, carbon dioxide moves beyond its liquid phase to form solid and immobile hydrate crystals, further boosting the system's stability. The scientists say that thus stored, the gas would be secure enough to withstand even the most severe earthquakes or other geomechanical upheaval.

Interesting commentary on Lebanon

Stopping the battle would not mean stopping the war on Israel - Opinion

The above piece is from The Age today, and takes a sceptical line on the calls for Israel to stop when there is no permanent solution in the pipeworks.

The article makes many good points. I like this one in particular:

The conventional wisdom holds that any military action is counterproductive. The doves point out that the Israeli counteroffensive has boosted Hezbollah's standing in the Arab world.

Well, sure. But Hezbollah's prestige was also boosted by Israel's 2000 withdrawal from Lebanon. If aggressive Israeli actions boost Hezbollah, and conciliatory Israeli actions boost Hezbollah, then maybe Israel's actions aren't really the prime mover here. Maybe Hezbollah has figured out that it can become the champion of the Arab world by putting itself forward as Israel's chief antagonist.

Kids movies recently seen

Having children of primary and sub-primary age means that most of the movies I get to see are not exactly Citizen Kane. But, good movies for children can be enjoyable for adults, especially in the animated field, where the writers now spend much effort on adult oriented jokes. Some movies I have seen recently on DVD or the cinema:

Over the Hedge: not bad, not great. But (speaking of Citizen Kane) any movie which has an opossum (voiced by William Shatner) ending a prolonged fake death scene by saying "Rosebud" has got something going for it.

Madagascar: good. Some quite eccentric characters and good voice work made this quite enjoyable.

Sky Captain and the World of Tomorrow: A slightly weird exercise in over-the-top art deco/pulp science fiction style. Very watchable for its remarkable computer generated looks, it could have been much better if everything in it was not on such a ridiculously gargantuan scale. Checking Rotten Tomatoes, I had forgotten that it got quite a good overall rating, although even the good reviews had to admit the plot and script were lacking. (As one reviewer there says, "The only thing keeping it from greatness is a good story.") However, it went on to be a box office failure (well, $37 million). I suspect one of the reasons is that audiences don't care much for movies which seem to be in an alternative history setting. Also, even though I can quite like her on screen, Gwyneth Paltrow's line delivery seemed somewhat "off" here.

Wallace & Grommit - The Curse of the Were-Rabbit: While never over-excited by the W& G shorts, this movie was (to my surprise) funnier and more charming than the previous incarnations, and did not suffer at all from being extended to movie length. The rabbits are cute for the kids, the lampooning of English society works well for the adults, and Grommit continues his stoic ways.

Some useful suggestions on the Middle East?

A tale of two failed Mideast states | csmonitor.com

From the above article:

Washington should, accordingly, not take a passive "wait and see" approach to the increasing violence being exported from both the Gaza Strip and Lebanon, and the increasing lawlessness in those areas, but should rather act forcefully in order to make it clear that it will not allow Gaza and Lebanon to remain failed states.

This requires that the US and the international community: a) actively pressure Syria to end its involvement in Lebanon and its continued undermining of Lebanese sovereignty (despite its ostensible "withdrawal" from Lebanon last year); b) actively pressure the Lebanese government to deploy its Army in the south and to disarm Hizbullah (if necessary with the assistance of a multinational force); and c) move toward the establishment of some type of international trusteeship over the Gaza Strip, which will involve the deployment of multinational forces, possibly including Egyptian forces, to disarm militants in Gaza and stabilize the political, economic, and security situation there.

Israeli actions alone will not bring stability to these failed states and are likely to only temporarily weaken Hamas and other Palestinian factions, as well as the Lebanese Hizbullah. This is a problem of global dimensions, and only the world's sole superpower can take the lead in addressing it.


Seems to me the problem would be be with getting international co-operation in any multinational forces, and in particulare getting an Islamic country on board. (Will Egypt really want to be involved?)

Free storage space

AOL using Xdrive to offer free space - Los Angeles Business from bizjournals:

A couple of years ago, I tried using a free online storage service. It worked OK, but uploads were fairly slow (which probably says more about Australia's pathetically slow internet services than the storage service itself.) The free service I tried was soon stopped and became subscription only.

AOL is now to offer 5 GB free to everyone. How nice. Will it last?

Further co-operation from Iran

Defiant Iran threatens to use 'oil weapon' against sanctions - World - Times Online

From the above:

In a blunt response to international concern about Iran’s nuclear ambitions, Ali Larijani, the chief negotiator on atomic issues, said that Tehran was ready for a showdown with world powers when the matter was taken up by the UN Security Council this month.

“We will expand nuclear technology at whatever stage it may be necessary and all of Iran’s nuclear technology including the [centrifuge] cascades will be expanded,” he said in Tehran.

The announcement was regarded not simply as another rhetorical outburst from Tehran but rather the precursor of a formal reply to the West which will be delivered in full on August 22....


Mr Larijani said yesterday that Iran had a right under the nuclear Non-Proliferation Treaty (NPT) to build a civilian nuclear programme. He said Iran was planning to expand its operations at the heavily-guarded Natanz facility in central Iran, where the authorities hope to have 3,000 centrifuges — which enrich uranium by spinning it at supersonic speeds — operating by the end of this year. “We will expand nuclear activities where required. It includes all nuclear technology including the string of centrifuges,” he said. ”We won’t accept suspension.”

Why not just set up a big football field sized poster saying "Bomb me now (or as soon as you finish up in Lebanon)" ?

"But I'm not dead yet!"

New Scientist News - Not brain-dead, but ripe for transplant

Interesting article on doctors reconsidering when to treat patients as dead.

Against wind power

Matthew Stevens: The answer isn't blowing in the wind | News | The Australian

This is an interesting article explaining why wind power is not the great benefit that it would seem. For example:

...even in those states with the most ambitious renewables targets, South Australia and Victoria, the net effect of wind power on carbon dioxide emissions will be negligible, if not illusory. According to another recent study, if Victoria reaches its target of 1000 megawatts of renewable generation capacity by 2016 (the state currently boasts about 120MW of wind capacity), its share of national greenhouse gas emissions will fall from 32 per cent to 28 per cent by 2020.

But in raw numbers, Victoria's power plants will be pumping out 24 per cent more carbon dioxide by 2020 than they do in 2006 because, quite simply, Victorians will be using much more power.

I suppose it can still be argued that it is better to have some of that electricity produced by clean wind power than an alternative CO2 producing means, otherwise the total future CO2 output will be even higher than that already bad forecast.

But it would seem that the more important message is that, in reality, windpower is just fiddling around the edges of the problem. What's worse, such fiddling can give an impression of significance that is undeserved.

A long review article on mini black holes

What fun! Today I get to post about my two favourite subjects one after the other.

This link will lead you to a fairly lengthy review of issues around the possible production of black holes at the Large Hadron Collider at CERN. It's by physicist Greg Landsberg, to whom I give some credit for actually answering some emails sent to him by James Blodgett, the author of the Risk Evaluation Forum site (see link in my blogroll.) Blodgett's site got me interested in this whole topic.

Landsberg does not think there is anything to Blodgett's concerns, but at least he was respectful in his answers.

Anyway, Landsberg's article above is interesting in several respects:

1. He confirms clearly that Hawking Radiation is never going to be observed directly at astronomical distances (it is far too weak - see pages 8 to 9.)

2. The entire article makes it clear how many different ideas there are about what exactly would happen in the decay process of a micro black hole.

3. Landsberg notes this:

Given the current lower constraints on the fundamental Planck scale in the model with large extra dimensions of ≈ 1 TeV [8], the black holes that we may be able to study at colliders and in cosmic rays will be barely transplanckian. Hence, the unknown quantum corrections to their classical properties are expected to be large, and therefore it is reasonable to focus only on the most robust properties of these mini black holes that are expected to be affected the least by unknown quantum gravity corrections.

Later, he writes:

In quantum gravity, it is expected that there is a fourth, Planckian stage of black hole evaporation, which is reached when the mass of the evaporating black hole approaches the Planck scale. The details of the Planckian stage are completely unknown, as they are governed by the effects of quantum gravity, which should be dominant at such low black hole masses. Some authors speculate that the Planckian stage terminates with a formation of a stable or semi-stable black hole remnant with the mass ∼ MPl. Others argue that the evaporation proceeds until the entire mass of the black hole is radiated. The truth is that no predictions about the Planckian regime are possible, given our lack of knowledge of quantum gravity.

This has been said before: I just thought that it is nice to see such a blunt and direct statement of ignorance.

4. Despite this, Landsberg expresses no doubts at all about Hawking Radiation applying to micro black holes. (It is expected to occur before the black hole reaches Planckian scale and its behaviour becomes guesswork.)

5. Landsberg notes that it has been suggested that instead of (or as well as?) mini black holes, the LHC could create other things such as string balls (don't ask me) or this:

Another possibility is a production of higher-dimensional objects, e.g. black p-branes, rather than spherically symmetric black holes (p = 0) [48].

First time I have heard of that. Did the safety review of the LHC take these into account?

6. The article appears optimistic on the possibility of the by products of naturally occurring mini black holes being detected in neutrino telescopes being built. If this is confirmed, then any of my concerns about Hawking Radiation not occurring would be gone.

7. Landsberg raises one point in such a way that I cannot understand whether it is a potential danger to the LHC or not. This is heavy going, and I refer the interested reader to section 10 of the paper on page on page 27. It seems to me that he may be saying that, on some models, it may be possible for a mini black to evaporate quickly with the equivalent energy of a few hundred pound bomb. This sounds dangerous to me, but as I say, I could be misunderstanding him here. (I would be happy to hear what other reader's think he means.)

How cats control the world

LiveScience.com - Study: Cat Parasite Affects Human Culture

Regular readers know that this is a favourite topic here - the dreaded Toxoplasma gondii that may drive people mad.

This report suggests that it might also just make many of the infected (about half of the world's population!) neurotic, and this in turn might affect entire cultures:

...Lafferty wondered whether high rates of T. gondii infection in a culture could shift the average personality of its individuals.

"In populations where this parasite is very common, mass personality modification could result in cultural change," Lafferty said.

The distribution of T. gondii could explain differences in cultural aspects that relate to ego, money, material possessions, work and rules, Lafferty added. In some countries, infections by the cat parasite are very rare, while in others nearly all adults are infected.

To test his hypothesis, Lafferty looked at published data on cultural dimensions and average personalities for different countries. The countries examined also kept records of the prevalence of T. gondii antibodies in women of childbearing age. Countries with high prevalence of T. gondii infection also had higher average neuroticism scores.

"There could be a lot more to this story," Lafferty said. "Different responses to the parasite by men and women could lead to many additional cultural effects that are, as yet, difficult to analyze."

What I want to know is the rate of this infection in Muslim countries. Maybe the whole Middle East crisis is due to cats. (Just a theory.)

Things I don't understand about Iraq

Top generals see threat of Iraq civil war - Reuters.com

Of course, Iraq's slow burn civil war-ish thing is getting worse, but the political situation on the ground seems not to be attracting much in the way of commentary or analysis since Hezbollah decided to light up a front on Israel.

Here are some things I admit to not understanding about the situation in Iraq:

1. What are the ultimate goals of the warring Sunni/Shia factions? Does either of them think they can drive the other out of political power entirely, or (who knows?) out of the country entirely? Given that each group is sizeable, the entire removal of the other isn't an option seriously believed, is it?

2. I heard once on Phillip Adams radio show that there is a high degree of intermarriage between Sunni and Shite in Iraq, and this was believed by some commentators to be a major reason why there would not be a "full blown" civil war. Sounds like a good theory, but why is it not working to curb the terrible fighting even at these current levels (about 100 people a day)?

3. Last night, I saw a report on a bombing of a group of school boys (I forget which faction they were in, but they were just in a park at the time.) What sort of point does any faction think it is achieving by killing unarmed civilians, especially children? And if the intermarriage point mentioned above is true, surely attacks like that only hurt both Sunni and Shite when the families are mixed.

4. Seemingly, it remains impossible to disarm militias in Baghdad. Why exactly is that the case?

I am sure there are more points I could ask, but I need to do other things right now.

How quickly could Iran go nuclear?

The New Yorker: Online Only: Content

The New Yorker, not known for being a right wing panic merchant, runs an interview this week with (journalist?) Steve Coll that is worth reading.

Mr Coll notes that on the question of how quickly Iran could have a nuke:

John Negroponte, the director of National Intelligence, has said, in his most recent public assessment, that the American intelligence community believes that Iran may acquire a nuclear capacity some time in the next decade, meaning from 2010 or 2011 onward. From my reporting, I gather that in private briefings the Bush Administration’s intelligence analysts focus on a five-to-seven-year window, although they emphasize that there’s a fair amount of uncertainty about this estimate. I think the one assertion that the intelligence community seems comfortable with is that it’s not this year or next year and probably not the year after that. However, the more that is discovered about Iran’s research, the more some analysts wonder whether Iran might be able to move faster than the official forecast indicates.

It gets worse, though:

[Interviewer] Once the centrifuges are working, how long will it take to make enough material for a bomb?

It depends on how many centrifuges you put into your plant. The math is fairly straightforward: a cascade of a hundred and sixty-four centrifuges can produce so many grams of highly enriched uranium in so much time if the centrifuges are operating around the clock. Iran has said that it intends to install three thousand of these centrifuges by the end of this year. That seems like an ambitious goal, but let’s assume the Iranians could achieve it. If they did, they could manufacture enough highly enriched uranium for a couple of bombs within a year if they operated those centrifuges around the clock. Most people don’t think they can pull that off, but that’s the scale of their operation at this point.

Some other bloggers have noted that while terrorism in Southern Thailand is reported, it doesn't seem to attract much in the way of commentary or analysis.

This article indicates that there is considerable disagreement about whether the Islamic separatist movement is behind all the trouble, or only part of it.

Anyway, things are not looking good:

Three Thai policemen and a soldier were killed in two separate incidents Wednesday, only hours after a series of over 100 attacks in southern Thailand, which has been riven by an Islamic separatist insurgency.

Why is John Howard popular with younger voters?

There have been quite a few images in the Australian media recently of John Howard being accosted by enthusiatic young supporters. Matt Price has noted the PM's recent popularity too.

Does polling confirm this general impression of popularity with youth? A recent Newspoll showing demographic breakdown over the last couple of years pretty much does. To get to it, go here and look for the link to 23/06/06 "Geographic and Demographic Analysis..."

The interesting thing is that while Howard is clearly most popular with the over 50 demographic, his satisfaction rating is sometimes higher with the 18-34 year olds than the 35 - 49 year set. Dissatisfaction with Howard is sometimes higher in the "middle age" bracket too. There's often not a great deal in it, though.

The Newspoll survey shows that voting intention in the 18-34 yr olds is usually pretty evenly split between Lib/Nationals and Labor, with usually only one or two percent higher on the Labor side. (Of course, perhaps the younger crowd tend to favour the Greens too, so preferences from them may help Labor.)

So it would seem that it is certainly not the case that you can argue that on voting intentions, the younger ages are strongly conservative. (Perhaps they are more conservative now than in previous decades; I don't know.) Yet their satisfaction with Howard is quite high. (And unfortunately for Kim Beazley, they are often more dissatisfied with him than satisfied.)

Sometimes a degree of "dagginess" mysteriously reaches a certain level of "cool" amongst the young. (Rolf Harris seems a good example of this in the entertainment field.) I think that is part of Howard's current appeal to the young, mixed with admiration for his clear enthusiasm for the job, and the high degree of resilience he displays (this being a character trait that receives a lot of attention in child development circles now).

I have also always felt that he is a genuinely modest man, who (I like to imagine) has to pinch himself often to be sure he isn't dreaming while being received on the international stage. (He is still capable of appearing not entirely at ease, but I find that oddly endearing.) I presume that others share this view, even if they don't agree with all of his policies.

UPDATE: Janet Albrechtsen gives her view of Howard's popularity today, and it's hard to disagree with her.

Under the rocks and stones/there is water underground

Looking for lunar caves as a possible place to set up a permanent colony on the Moon got brief mention here recently. One or two space scientists agree:

The Moon appears to possess long, cave-like structures called lava tubes that are similar to ones on Earth. They form when the surface of a stream of lava solidifies and the molten rock inside drains away, leaving a hollow tube of rock.

For decades, engineers and space scientists have discussed the possibility of using these caves as astronaut housing because they are sheltered from space radiation and micrometeorite impacts. But the idea should now be revisited in light of NASA's push to send astronauts back to the Moon, says Austin Mardon of the Antarctic Institute of Canada in Edmonton, Alberta.

At a meeting of the International Lunar Exploration Working Group (ILEWG) in Beijing, China, last week, he argued that robotic probes should be sent to potential lava tubes to see if they are suitable for habitation.

He says erecting pressurised tents inside a cave would be easier and faster than trying to construct a rigid structure on the surface. "Instead of assembling structures that have to be meteorite-proof on the surface, or burying them, you'd have tent-like structures inside these tubes," Mardon told New Scientist. "It's like being cavemen on the Moon."

"It’s a potentially very inviting place to put infrastructure,” agrees Mark Robinson of Northwestern University in Evanston, Illinois, US. He says sections of the lava tubes with roofs still intact appear to be very stable, having survived for 3 billion years or more since their formation.

But he points out that the lava tubes may not be located where NASA would like to send astronauts. For example, the polar regions – which may harbour water ice that could be used to support a lunar base – appear to bear no sign of the ancient lava flows associated with lava tubes.
That's a pity.

As to how NASA intends looking for water on the Moon, it's hoping to try smashing something into it, and sniffing the plume for water. A previous attempt at something similar was not successful, and in fact I would guess that the new attempt may simply be unlucky too, even if some water is around.

Wouldn't a few astronauts with a couple of drills and some explosives stand a much better chance?

About Mel

Unfortunately (as I don't want reader's thinking I just made this up), I have never mentioned before on this blog something that I have said to family: I have never liked Mel Gibson or his movies. It's not an opinion that can easily be rationalised; being one of the few "conservatives" in Hollywood, you would think I would have found something to like about him. (I also have not seen The Passion of the Christ, which I might like, but I have my doubts.)

Now that I feel justified in my dislike of him, I should mention a few other actors I just don't like in case they get into trouble too: Clint Eastwood (the critical acclaim given to "Unforgiven" was incomprehensible); Jim Carrey (I never get any sense from any interview I have seen that there is a "real" person inside that body at all; he's just creepy); and ...I am sure there is another one lurking in the back of my mind, but he or she won't come out right now.

Another good Neo Neocon post

This one deals with Ariel Sharon's views on the basic issue behing the Palestinian/Israeli conflict, as noted in a New Yorker article from the start of the year. Interesting reading as always on Neo Neocon.

No need to actually read him now

The New Yorker: The Critics: Books

Don't know much about Samuel Beckett and his works? Me neither, but I know more now having read the above article. The author seemingly admires Beckett, but many of his comments do nothing to encourage this blogger to actually read him:

Emptying his books of plot, descriptions, scene, and character, Beckett is said to have killed off the novel—or else, by showing how it could thrive on self-sabotage, insured its future....

One of the most purposely obscure writers of the last century has become all things to all people...

The Beckett of the novels is not a very efficient writer—exhaustion is his method—but he can probably condense more cackling blasphemies onto a single page than anyone else....

...Beckett is, however, a hard read. His plays continue to be performed, but as a novelist—and he considered playwriting “mainly a recreation from working on the novel”—he is increasingly more honored than read. This is too bad, because Beckett’s fiction, whether or not it is the summit of his achievement, is its heart. Meanwhile, vague and grand ideas about Beckett flourish because he goes unread. “A voice comes to one in the dark”: this, the first line of the late novella “Company,” also describes the ideal situation of his contemporary reader, as innocent and as apprehensive as that, as ready to be startled. Strange stuff, this work, that life.

The article usefully extracts some bits from Beckett's novels, just to confirm how tiresome reading him can be:

Here he moved, to and fro, from the door to the window, from the window to the door; from the window to the door, from the door to the window; from the fire to the bed, from the bed to the fire; from the bed to the fire, from the fire to the bed; from the door to the fire, from the fire to the door . . .

Think Beckett can’t go on? He can go on. In this case, for another thirty lines.

Good of the New Yorker to confirm a suspicion that I am not missing anything, other than tedium.

Weather talk

Reuters AlertNet - US hurricane expert stirs global warming debate

Seems it's still not clear whether hurricanes are worse than before.

In Brisbane, it seems to have been a mild winter. Roses here can flower all year around (if you don't do a winter prune), although they obviously slow down in winter, and the buds take a long time to open. This last couple of weeks, a couple of the rose bushes in my yard have had a sudden flush of blooms. I also noticed a neighbours tree that looks something like a flowering plum or peach is starting to bloom. All signs, I think, that it has indeed been a milder winter. Summer could be a stinker, it seems.

The strange world of the placebo

Nothing can cure you - Health - Times Online

The link is to an interesting story on the placebo effect, and in particular how it is a large part of the complementary medicine story.

It does seem odd that an effect that is known to be quite powerful cannot really be used by doctors due to ethical/legal issues. (This didn't stop Dr House on the TV show "House" using it last week, though.)

One study is mentioned in the report which I think may have missed at the time:

Four years ago, a big study examined two popular treatments for depression: the herbal remedy St John’s Wort, the antidepressant tablet Zoloft, and a placebo. It revealed, amazingly, that the placebo was more effective than both of them.

Is there any way around the problems of how you could allow placebo to be legitimately used beyond the confines of medical studies? It would be tricky, I know, but it does seem a pity that only fictional doctors ever do it.

On the Shia/Sunni divide

The Tablet

The link is to a pretty good article in The Tablet talking about the Shia in the Middle East, and what the future may hold. As a summary of who is where, and who holds political power, this paragraph is useful:

Shia beliefs are held by perhaps one in 10 Muslims today - some 140 million people. Only Iran is overwhelmingly Shia, where they form 90 per cent of the population. Across the Persian Gulf, the littoral states with significant proportions of Shia include Kuwait, with 30 per cent of its population, Bahrain with 75 per cent, Saudi Arabia with 10 per cent, Qatar with 16 per cent and the United Arab Emirates with just 6 per cent. Approximately half of all Shia live in the arc beginning in Lebanon, with 45 per cent of its population being Shia, and ranging through Iraq with 60 per cent, Azerbaijan with 75 per cent, Afghanistan with 20 per cent to Pakistan, also with some 20 per cent.

In Syria, the ruling elite is Alawite, a Shia- affiliated group with just 15 per cent of the country's people. Alawite domination has bred deep resentment among many of Syria's Sunni Muslims who constitute 70 per cent of the population. Uprisings by Sunni Islamists in the early 1980s were partly fuelled by this sectarian divide.

The author suggests that (as I had said somewhere in comments before), the invasion of Iraq should logically be only a positive to Iran, due to the empowerment that it gave to Iraqi Shia:

Despite the history of Iraqi nationalism, Arab and Persian mutual suspicion and the legacy of the Iran-Iraq war, Iran is not displeased with the changes in the region and will not want to "rock the boat" irredeemably. Before recent changes, Iran considered itself surrounded by hostile Sunni states: Iraq and Saudi Arabia to the West and Afghanistan and Pakistan to the East. It would not want to see "anti-Iranian Arab nationalism" championed by Sunnis to emerge as a threat.

But if that is the case, why is it acting so belligerently about the having an un-monitored nuclear enrichment program?

The superconducting future

Science & Technology at Scientific American.com: A Power Grid for the Hydrogen Economy

This is a very futuristic sounding idea for a superconducting electricity grid that is cooled by hydrogen. Thus the grid distributes hydrogen as well as electricity. (It is also going to involve new, better designed, nuclear power stations.)

Sounds technically challenging, but still, the future has to start somewhere.

Have spacesuit will travel

New Scientist SPACE - Future spacesuits could heal themselves

The spacesuit would be self-healing because its innermost layer, which provides the spacesuit's airtight seal, is filled with a thick polymer gel. The rubber-like gel is sandwiched between two thin layers of polyurethane so that if a hole forms in these layers, the gel oozes from surrounding areas to plug it. In vacuum chamber tests, the gel healed punctures up to 2 millimetres wide.

Cool.

One other problem for new lunar spacesuits: accounts of the Apollo missions made it clear that a significant problem was the amount of moon dirt that stuck to the suits and got dragged into the Lunar Module. From another article:

The moonwalkers of the 1960s struggled with the fine, powdery dust that covered their spacesuits. Back inside their tiny one-room cabin, it got everywhere-in the machinery, in their eyes, in their throats.

Scott said that moon dust even got in the connectors between the backpack and the spacesuits."You could almost hear them grind after three days," he said. He ranks dust as "the major problem for a long stay."

I assume that for a habitat on the Moon, they will have to devise some decent way of getting fine dirt off the suits so it is not dragged in through the airlock. (The Apollo lunar module did not have an airlock at all, which was a major problem. ) But even with an airlock, seems to me there will still be a problem unless you can use some fluid or cleaning device of some kind to use. Would a really efficient vacuum cleaner work?

UPDATE: by co-incidence, I just found this snippet about the Apollo spacesuits in a Tech Central Station article (it's a review of a book for kids about the Apollo program):

A central theme of Team Moon is that a large number of people -- the 400,000 of the subtitle -- pooled their talents to make the mission happen. These included, for instance, the seamstresses of the spacesuits worn by the astronauts. The suits consisted of 22 layers of materials such as Mylar and neoprene-coated nylon that were stitched and glued together by a team at the company ILC Dover. Team members had a great deal of confidence in the extensively tested suits, but still felt pangs of worry when, as recalled by seamstress Eleanor Foracker, "the guys on the moon started jumping up and down."

Insects displaying common sense

ScienceDaily: Male Praying Mantids Prefer Not To Be Victims Of Sexual Cannibalism

Gotta love a headline like that. From the article:

Lelito and Brown thus varied female hunger and physical orientation in order to assess how male mantids respond to variation in the risk of cannibalism. They found that males responded to greater risk by slowing their approach, increasing courtship behavior, and mounting from a greater – and possibly safer – distance.

"This shows that male mantids actively assess variation in risk and change their behavior to reduce the chance of being cannibalized," explains Brown. "Males are clearly not complicit, and the act of sexual cannibalism in praying mantids is an example of extreme conflict between the sexes."

Good to know.

My suggestion for the Iranian problem

With regards to Iran and its nuclear program, I wonder whether the use of an electro magnetic pulse via either a nuclear explosion or a conventional "electronic bomb" has been discussed in Washington. It doesn't seem clear how far advanced the US is with non nuclear e-bombs, but there is a lengthy Australian article about them here. A short New Scientist article is here.

Last year, the US Senate thought about the possible consequences of a nuclear EMP attack from Iran on the United States, and some right wing Christian websites made much of it for a time (possibly that was all a beat up).

But I can't find anywhere yet that has discussed an attack in the opposite direction. Using such weapons against Iran as a first attempt to dissuade from the nuclear research would have many advantages. A nuclear EMP attack seems too big; by the sounds of it, if done at high enough altitude (which basically means in space) the effects on the power grid could extend well into neighbouring countries. If done at night, the giant glowing cloud in the sky shoud have considerable psychological impact though.

OK, first attempt could be by non nuclear e-bombs, which (as far as I can tell) detonate high above the targets and are largely non lethal on the ground (unless you use a pace maker, perhaps). It would seem that non nuclear ones would have a much narrower affected area.

The hope would be to fry all of the electronic equipment in the labs, and the power supply to them, without ruining the entire country's power supply. If such bombs can be delivered by cruise missiles, so much the better. If Iran laughs that off, then how about a really small nuclear one not too high over a desert area?

I trust no one from Iran reads this blog.

UPDATE: just to clarify, when I talk of a small nuclear one over a desert area, I am talking at high-ish altitude for the purpose of demonstrating EMP. I am not suggesting a nuclear strike on the ground. The nuclear EMP that is talked about most often, the Starfish Prime test in 1962, was well out into space, and didn't do satellites much good either. The Wikipedia entry on this is really good. Another Wikipedia entry talks about other high altitude tests in the 1960's - I didn't realise that so much had gone on at the time. Another long entry on EMP from nuclear devices is here. Seems the lowest altitude mentioned is about 40km, well below earth orbit.

Anyway, obviously a nuclear explosion anywhere in the atmosphere is not going to go over well with the Greenies or the UN. Also, it seems that the effectiveness of any EMP attack (non nuclear or nuclear) is going to be very hard to judge for the attacking country. (Especially if you are attacking underground facilities.) I wonder if that is the biggest disadvantage they have?

All interesting stuff for armchair generals to think about in any case.

A way to escape the end of the universe?

[hep-th/0607137] Some notes on the Big Trip

There's some unusual stuff to be found at arXiv.

Can't say that I had heard of the "Big Trip" before. From the paper itself:

Rather bizarre implications from dark energy models are now being considered that might ultimately make the
future of the universe sings a somehow weird melody. It has been in fact recently proposed [1] that if the current value of the equation-of-state parameter w would keep up being less than -1 in the future, then the throat radius of naturally existing wormholes could grow large enough to engulf the entire universe itself, before this reached the so called big rip singularity [2], at least for an asymptotic observer. This rather astonishing result - which has been dubbed the ”big trip” - has proved to be not free from a number of difficulties...

It will be seen that none of the problems (1), (3) and (4) indeed hold for the asymptotic observer, and that problem (2) is a debatable one and might require considering the big trip to take place within the context of a multiverse scenario.

The whole universe disappearing down a worm hole. That would be something to see.

Why Lance Armstrong got better?

BBC NEWS | Health | Heat may be key to cancer therapy

The theory is that cancer cells from testicular cancer are more susceptible to heat, given that their original home is a few degrees cooler than the rest of the body. Sounds plausible.

This reminds me, I am pretty sure there was an Arthur C Clarke novel in which brief mention was made of human males in the future no longer having external genitalia, including testes. The difference between men and women only became obvious on arousal. I think that this was the result of genetic manipulation to improve the design of males. (I hope this is a real memory and I am not relaying some stupid dream!) It seemed to me a very unlikely thing to bother genetically manipulating.

I think it was also Clarke who mentioned a character putting a cream on his face to inhibit beard growth (instead of shaving.) I think of that quite often as I shave in the morning, as it strikes me as a product that sounds a likely prediction, but turns out to be far off the mark.

It's funny how the mind can keep remembering some of the most minor details of novels.

Hope for young soldier

Guardian Unlimited | Special reports | Palestinian groups agree deal for return of Israeli

From the Guardian:

Palestinian factions, including Hamas and Islamic Jihad, have agreed to stop firing rockets at Israel and to free a captured Israeli soldier in a deal brokered by Mahmoud Abbas, the Palestinian president.

The deal, agreed on Sunday, is to halt the rocket attacks in return for a cessation of Israeli attacks on the Gaza Strip, and to release Corporal Gilad Shalit, the Israeli soldier captured on June 25, in exchange for the freeing of Palestinian prisoners at some point in the future.

An adviser to Mr Abbas told the Guardian that all Palestinian politicians were united on the need to free the Israeli soldier and stop all violence in Gaza, but the obstacles were the Israeli government and the Hamas leadership in Damascus.

I don't understand

Independent Online Edition > Health Medical

Because I can't get free access to this report, or to the BMJ article, I can only see this introduction, and I don't see how his argument works:

A leading doctor has accused Western plastic surgeons who perform cosmetic surgery on the vagina of undermining the battle against female circumcision in other parts of the world.

Writing in the British Medical Journal, Ronan Conroy, senior lecturer at the Royal College of Surgeons in Ireland, says the growing acceptance in Britain and elsewhere of so-called "designer vaginas" was exposing Western double standards.

I mean, aren't "designer vaginas" intended to enhance function, and female circumcision doing the exact opposite?

Everything in moderation

ScienceDaily: Light To Moderate Drinking Reduces Risk Of Cardiac Events, Death

OK, maybe you knew that before, but a new study confirming it doesn't hurt.

This one points out that the idea that the cardiac benefits of alcohol may be due to its effect on inflammation doesn't seen right. It seems that no one yet knows clearly why it does work:

The findings indicate that the anti-inflammatory properties of alcohol alone do not explain the reduced risk of death or cardiovascular disease associated with light to moderate drinking, the authors write. Alcohol may have cellular or molecular effects that reduce the risk of cardiovascular disease, or it may interact with genetic factors to produce a protective effect.

The health effects of alcohol may not be the same for everyone, the authors caution. "The net benefit of light to moderate alcohol consumption may vary as a function of sex, race and background cardiovascular risk," they conclude.

Mark Steyn on the Middle East

Mark Steyn: If only they had refused to indulge Arafat | News | The Australian

All of the article is good Steyn stuff. An extract:

For the first quarter-century of Israel's existence, the Arab states fought more or less conventional wars against the Zionists and kept losing. So then they figured it was easier to anoint a terrorist movement and in 1974 declared Yasser Arafat's Palestine Liberation Organisation to be the "sole legitimate representative of the Palestinian people", which is quite a claim for an organisation then barely a decade old. Amazingly, the Arab League persuaded the UN, the EU, Bill Clinton and everyone else to go along with it and to treat the old monster as a head of state who lacked only a state to head.

It's true that many nationalist movements have found it convenient to adopt the guise of terrorists.

But, as the Palestinian movement descended from airline hijackings to the intifada to self-detonating in pizza parlours, it never occurred to its glamorous patrons to wonder if maybe this was, in fact, a terrorist movement conveniently adopting the guise of nationalism.

Matt Price makes this comment in his short piece on John Howard's birthday:

These days the Prime Minister is routinely mobbed during public appearances and Wood reckons more than 400 people from a mix of community groups will make it for a cuppa with the birthday boy.

"You normally get a high proportion of no-shows, but practically everyone we asked is turning up," said Wood.

Wig and robes not enough

From the story above:

A PROMINENT New Zealand lawyer - bald and moustachioed - turned up to court wearing a skirt and blouse and carrying a handbag to protest what he says is a male-dominated judiciary.
Rob Moodie, 67, fronted Wellington's High Court yesterday dressed in a navy blue skirt suit with added female extras, The Dominion Post newspaper reported.

"I will now, as a lawyer, be wearing women's clothing," Mr Moodie was quoted as saying .

"The deeper the cover-up, the prettier the frocks."

Any more than guesswork?

Minister ignored parrot advice - National - theage.com.au

While what went on behind Senator Ian Campbell's decision to not approve a new Victorian wind farm is no doubt interesting, this part of the report seems odd:

While refusing to comment on why the departmental briefing paper would not be released, a spokeswoman for said Senator Campbell had based his decision on a publicly available report by consultants Biosis Research, which warned that orange-bellied parrots face extinction within 50 years. There are only about 200 left.

Yet the same Biosis Research report also predicted that the risk of any parrots being killed at the Bald Hills site was extremely low.

According to the Biosis risk analysis, the worst-case scenario would result in one parrot being killed at Bald Hills every 667 years. In the best-case scenario, that would fall to one being killed every 1097 years.

How on earth would you forecast with any high degree of accuracy the rate of bird kill for a particular species in an area that has not had a wind farm in it before?

Sounds like rubbery figures to me.

Mum-in-law from hell

Mother-in-law made to pay (pounds) 35,000 for inflicting four wretched months - Britain - Times Online

An Indian arranged marriage goes wrong, and the daughter in law successfully sues the mother-in-law from hell under legislation designed to cover stalkers. I can't think of equivalent legislation in Australian jurisdictions that could work here.

From the article:

Ms Singh was 22 and a manager in her family’s clothing business when she married Hardeep Bhakar, then 25, from Ilford, East London, on November 1, 2002. Their families had been introduced by a matchmaker. She had expected to live with her husband’s family after the marriage.

But she soon began to have doubts about her new home, which she shared with Hardeep and his two brothers as well as Mrs Bhakar and her husband, Prithvipal Singh Bhakar. Ms Singh and Mrs Bhakar were often alone in the house together while the men were out.

Mrs Bhakar attempted to exhaust and humiliate her daughter-in-law, requiring her to clean toilets without a brush and clean the floor without a mop. Her hands became infected. Ms Singh’s visits home were restricted and she was not allowed to attend her uncle’s funeral or make regular visits to the Sikh temple. Her mobile phone was confiscated and she was allowed to make and receive only one closely monitored call a week to her family.

Sounds a lot like a pandora's box of litigation being opened, all the same.

The Tablet on the Middle East

The Tablet

The opinion piece above is entitled "Disporportionately deadly" and states the reasons why the writer believes Israel, which he supports generally, should be condemned for an excessive response to Lebanon/Hezbollah.

The article is reasonably well written, and covers a lot of ground about what all the players may want to achieve.

I would criticise the article on some important counts, however:

1. Most importantly, while emphasizing that the laws of war incorporate the concept of proportionality, the article fails to note that the same laws prohibit use of civilians as a shield. This is quite a glaring omission in the circumstances.

To be more accurate in targeting Hezbollah assets on the ground, given that they are apparently hidden within civilian buildings, an invasion far into Lebanon would be necessary, which (in this particular case) carries the added risk of involvement of Syrian and Lebanese (as opposed to Hezbollah)
troops, as well as street to street ambushes and fighting. While not flattening as many residential buildings as bombing from the air, this style of fighting is not exactly going to leave the neighbourhood pretty. (And, I wonder, while it might result in a lower level of destruction in any particular street, would it be over a wider area?)

2. The article says of the response of Bush, Blair and (Canadian PM) Harper:

It is conceivable that one or more of them believes, along with tens of millions of evangelical Christians, that another war between Israel and its neighbours is a necessary precursor to the second coming of Christ.

Raising this seems rather unnecessary if you are unable to find any statement by any of the 3 that they believe this.

I note that has been much speculation by Bush opponents over the years that he probably believes this, especially with his ties to some evangelical Christians who do take the "end times" stuff very seriously. (Let me be clear: it is absurd and offensive for those nutters who believe this is the start of the "end times" to cheer on conflict in the Middle East.)

However, I have not been able to find any quote from Bush's mouth that confirms that he personally believes this. (A generic statement that he believes it is "God's will" that there be peace in the Middle East is not going to cut it. Correct me if I am wrong about this; it seems to me he must have been asked the question directly sometime in his political career, but I haven't found it on the internet yet.)

To worry unduly about Bush's personal belief about this has always struck me as a case of "guilt by association", and an example of many on the Left's general dislike of conservative Christianity getting carried away.

Besides, the number of people involved in executive power in the US system surely makes it extremely unlikely that any President with a belief in his personal apocalyptic role is going to get far with launching the missiles.

Whether you can have the same expectation from an out and out theocracy is another question.

3. The article also says:

President Bush and his advisers have several reasons for wanting a conflict with Iran. They have a score to settle concerning the 52 Americans who were held hostage for 444 days after the Islamic revolution of 1979. They are concerned about Iranian influence in Iraq and - at a time when China and Russia are emerging as serious competitors - have an eye on Iran's immense oil reserves also. A confrontation with Iran could also boost the Republican Party's prospects in the mid-term congressional elections in just three months.

Hmm. It could also be that they have a legitimate concern about another nuclear power in the Middle East with a recurring dream of removing Israel.

4. His final paragraph:

If we accept Israel's response and then tolerate it, we would be devaluing the lives of Lebanese citizens. We would also undermine the laws of war, which exist to prevent unnecessary human suffering without regard to national, religious or ethnic differences. Israel has a right to defend itself, but always within recognised and reasonable limits. Those limits have been breached. Friends of the Jewish state should not pretend otherwise.

Again, it would be good to see a statement that fighters who hide assets and themselves within civilian buildings (and then provoke a conflict) are also "devaluing the lives of Lebanese citizens."

For the record: Israeli targeting of some infrastructure appears to me to be of no military or even "political" use in the conflict, and should be criticised. (Power stations seems the most likely example - as no one seems to suggest that Hezbollah has a manufacturing base in Lebanon, and I don't know how having the power on would help them launch missiles.) Some infrastructure attacks may have a military point: preventing Hezbollah movement and resupply being the obvious one. There are some claims of escaping civilians being deliberately targeted. If it can be shown to have been deliberate, that is a war crime no doubt. It's just that I find it hard to believe this is a matter of Israeli policy, and in most cases would suspect mistake more often than war crime.

The whole problem is, without more detail, I have a hard time judging what attacks are justified or not. Judging from media reports alone is also tricky; a devastated Beirut suburb looks bad; it is bad. But it was always on the cards that this would happen if Israel wanted to stop the attacks. That's the evil of this asymmetric war stuff. It's dirty and nasty.

Hopefully, both sides will stop soon, and that is probably in Israel's interest too.

Why does Koizumi bother?

CNN.com - Polls: Japanese oppose shrine trip - Jul 23, 2006

With the recent revelation that the late Japanese Emperor Hirohito gave up visiting Yasukuni Shrine due to it adding war criminals to the list of the honored, and this article indicating that only 33% of Japanese actually clearly approve of the visits, you have to wonder why Prime Minisiter Koizumi bothers to insist that he still visit.

I suppose it could simply be all about saving face now. A sudden stop would seem an implied admission that he was wrong in the past.

Like whale hunting, which seems to also have no significant support in the Japanese public, this a bit of Japanese political behaviour which is strange to Western eyes.

At least the polls give some vague hope that the next PM will stop the visits.

Always time for more micro black hole talk

Seed: What if Black Holes Didn't Exist?

The article above gives a short explanation of an idea of a couple of physicists that black holes may not exist at all. There would still be things called "dark energy stars," which might act like astronomical black holes. One important difference would be (according to the Wikipedia entry on this theory) that they would not evaporate via Hawking Radiation.

I suspect this may be relevant to the issue of safety of micro "black holes" that might be created at the CERN particle accelerator, but whether it is good news or bad news in that regard is beyond me.

Something positive for a change

Irshad Manji: Faithful consider liberal reforms | Opinion | The Australian

Interesting story about an important move to liberalise some parts of Islam in Pakistan (and elsewhere.)

Unfortunately, some movement in the other direction goes on in regional government in Indonesia. SBS's Dateline did a story on this recently. As George Negus was away at the time, I could bear watching it.

Sounds unreasonable

Iran: Israel doomed to 'destruction' | Jerusalem Post:

Iran's president, Mahmoud Ahmadinejad, declared Sunday that Israel had "pushed the button of its own destruction" by launching its military campaign against the Iranian-backed Hizbullah militia in Lebanon.

Ahmadinejad didn't elaborate, but suggested Islamic nations and others could somehow isolate Israel and its main backers led by the United States. On Saturday, the chairman of Iran's armed forced joint chiefs, Maj.-Gen. Sayyed Hassan Firuzabadi, said Iran would never join the current Middle East fighting....

In Teheran, the government has sanctioned billboards showing Hizbullah leader Sheik Hassan Nasrallah and a message that it is the duty of Muslims to "wipe out" Israel.

Sounds reasonable

NewsDaily: TopNews -- Israel may accept a political Hezbollah

"To the extent that it remains a political group, it will be acceptable to Israel," Israeli Ambassador Daniel Ayalon said. "A political group means a party that is engaged in the political system in Lebanon, but without terrorism capabilities and fighting capabilities. That will be acceptable to Israel."

Fisk alert

A farewell to Beirut - In Depth - theage.com.au

The Age runs a Robert Fisk story from The Independent.

Certainly, Beirut sounds like it's been an unlucky city for centuries.

Just don't expect any subtle analysis of the current crisis, though. As a piece of current journalism/commentary, it suffers from Fisk-ness to a high degree.

Just in case you need more background

Proxy war | Features | The Australian

There's certainly no lack of commentary and articles giving background on the Middle East crisis, but the one above in today's Australia seemed a particularly good one to me, and filled in a few gaps in my previous knowledge.

No Sense Left

Early reviews for M Night Shayamalan's latest film, "Lady in the Water" are very bad. Sure, the Sixth Sense was creepy, but as all critics have noted, his films have been on a rapid decline in quality ever since, and this one looks like it has sent his reputation into freefall.

(This reminds me, on cable here some months ago there was what seemed intended to be a "mockumentary" about him. It was awful. )

Anyway, one of the reviews has this very funny paragraph:

If the film weren’t already feeble enough, Shyamalan insists on upgrading his signature cameo performances in his own films to that of featured supporting player. Shyamalan plays a novelist who lives with his "sister" in Cleveland’s apartment complex. Forget that M. Night Shyamalan’s acting skills couldn’t get him cast in a high school production of "Our Town." Watching a skilled acting craftsman like Paul Giamatti delivering lines to Shyamalan is like watching Robert Duvall talk to his cat about politics. It’s the one thing in the movie that sent shivers down my spine.

Sheridan's odd plan for peace

Israel has right motive but the wrong target | Greg Sheridan | The Australian

Greg Sheridan, somewhat to my surprise, clearly criticises Israel for blowing up bits of Lebanon, not just the Hezbollah units.

However, he ends on this note:

An Israeli strike against Syria's armed forces would have shown Assad he had to pay a price for Hezbollah's activities. Striking Lebanon, which is weak and cannot fight back, causes Assad, and the rulers in Tehran, no pain at all.

Not that I know how strong Syria is militarily, but wouldn't an attack on it have been something like throwing petrol on a flame to put it out?

A useful short history of Hezbollah

Hezbollah Evolution Opposition Proves Constant | The Jewish Exponent

It's from a Jewish source, but the tone it uses would suggest it's basically accurate.

What surprised me was the amount of funding from Iran for civilian services: $60 million a year. A radical organisation can sure curry a lot of favour with the locals with funding like that. This presumably led to its electoral success:

Running in June 2005 elections, Hezbollah won 23 seats in Lebanon's 128-member Parliament, and holds the Energy Ministry. Some hoped that political power would moderate the group and compel it to act more responsibly, but there has been little indication of a change in Hezbollah's outlook or behavior.

This involvement with government certainly complicates the moral issues over what are legitimate targets and what aren't.
