Background to Bundy

Bundy Ranch, vigilantism going mainstream: The idea that the Constitution is interpreted at the point of a gun isn’t new.

As the article says, the difference between the old constitutional vigilantism and the current version is support from the likes of Fox News and many in the Tea Party sympathetic Right wing blogosphere:
The protesters at Bundy Ranch voice the same rhetoric of constitutional vigilantism honed by the Klan, the Posse, and the militias. What has changed is that this philosophy is no longer limited to the radical fringe but has become a respectable position offered up by mainstream political figures like Nevada Sen. Dean Heller, who called the protesters “patriots,” and by a stream of Fox News commentators like Sean Hannity and Andrew Napolitano, who called Bundy a hero for standing up to federal abuse.
Emboldened by their apparent victory at Bundy Ranch, the new constitutional vigilantes are asking where they can take the fight next.  Cliven Bundy declared it a victory for “We the People.” But that can only be true if we want the Constitution to mean whatever an armed mob
says it means.
Stand proud, Rupert Murdoch.  Your search for ratings and profit is making America a more dangerous place.

Piketty responses

I haven't had time to read all of this, and will probably have a bit of trouble following some of the arguments, but Brad DeLong has an interesting looking summary of the reaction to Piketty, including the criticisms.

El Nino forecast update

I see that the BOM put out an update earlier this week, confirming that an El Nino is very likely, and could be confirmed by about July:
The likelihood of El Niño remains high, with all climate models surveyed by the Bureau now indicating El Niño is likely to occur in 2014. Six of the seven models suggest El Niño thresholds may be exceeded as early as July. 

The Pacific Ocean has been warming along the equator over recent weeks, with continued warming in the central Pacific likely in coming months. Another burst of westerly winds is presently occurring in the western Pacific, and is likely to cause further warming of the sub-surface.

El Niño has an impact across much of the world, including below average rainfall in the western Pacific and Indonesian regions, and increased rainfall in the central and eastern Pacific. For Australia, El Niño is usually associated with below average rainfall, with about two thirds of El Niño events since 1900 resulting in major drought over large areas of Australia.

The amazing, poisonous hypocrisy of the current Right wing tribalism

This article at Slate ("Conservative Tribalism") gives an account of some of the issues in American which the Right used to support, but about which they have done an about face for no apparent reason other than  Liberals (and Obama in particular) support them.   (The biggest example - the health care reforms that were good enough for Romney when he was governor, but are now supposed to be socialist extremism - turns out to be only one of many examples.)

And for a bit of humour, the ridiculous hypocrisy of Fox News on the Bundy confrontation was skewered perfectly by Jon Stewart recently.  You can watch it via Salon.

When will enough on the Right in America come back to common sense and send the Tea Party and their rich enablers packing?


Tattoo push back

BBC News - The ways tattoos can get you into trouble

It's not just religious sensitivities or cultural values at play. In October 2012, the head of the Metropolitan Police in the UK forbade police officers and staff from getting visible tattoos because they "damaged the professional image" of the force. The US Army has also just released a new rulebook on tattoos.
In addition to banning extremist, indecent, sexist and racist tattoos,
soldiers are now prohibited from having tattoos on their head, face,
neck, wrists, hands and fingers. Sleeve tattoos are banned below the
elbow and knee, with the number of visible tattoos - which must be
smaller than the size of the wearer's hand - limited to four. 
Excellent news.

Cannabis and hearts

I didn't see this one coming:
Marijuana use may result in cardiovascular-related complications—even death—among young and middle-aged adults, according to a French study reported in the Journal of the American Heart Association....

 Researchers note that marijuana use and any resulting health complications are likely underreported. There are 1.2 million regular users in France, and thus potentially a large amount of complications that are not detected by the French Addictovigilance System.

Economic guesswork (please see updates too)

Here are a couple of people with some apparent credentials in the field who think that the IPCC is doing a poor job at making accurate forecasts of the economic consequences of climate change.  (They seem to think it is being too optimistic.)

Common sense suggests they are right.

But while I would not want there to be less research on the topic, I'll repeat my gripe that I find it pretty incredible that anyone thinks that economic forecasting that extends beyond about a 10 to 20 year horizon, and which is trying to take into account large uncertainties in terms of the potential for natural disasters of a scale not seen since industrialisation, has any real hope of being accurate.

The simple point is - we do not want to have to re-order the world to meet a potential for 2 to 5 degree average global temperature rise (and a global rearrangement of rainfall that would surely also be involved) if we don't really have to.   Such an increase is self evidently going to be extremely disruptive (given that the difference between an ice age and a warm interglacial may be as little as 2.6 degrees), to countries both rich and poor, and the possible compounding effect of the types of natural disaster one upon the other are really impossible to foresee.

Economics should not be allowed to overrule common sense on this issue.  There is plenty of reason to assume some unprecedented disasters in terms of humanitarian, cultural and economic life, so act to limit the potential now.

Update:  for more detail on the confusing way economic analysis is used by the IPCC, you could do worse than read this post at Real Climate, and the comments following.

Update 2:  I note from poking around The Conversation (and finding a comment by Eli Rabbett) that there is other academic support for my common sense skepticism about applying economics to climate change.     Here is the abstract from a recent paper by Rosen and Guenther, which can be read in its entirety here:
The long-term economics of mitigating climate change over the long run has played a high profile role in the most important analyses of climate change in the last decade, namely the Stern Report and the IPCC's Fourth Assessment. However, the various kinds of uncertainties that affect these economic results raise serious questions about whether or not the net costs and benefits of mitigating climate change over periods as long as 50 to 100 years can be known to such a level of accuracy that they should be reported to policymakers and the public. This paper provides a detailed analysis of the derivation of these estimates of the long-term economic costs and benefits of mitigation. It particularly focuses on the role of technological change, especially for energy efficiency technologies, in making the net economic results of mitigating climate change unknowable over the long run.

Because of these serious technical problems, policymakers should not base climate change mitigation policy on the estimated net economic impacts computed by integrated assessment models. Rather, mitigation policies must be forcefully implemented anyway given the actual physical climate change crisis, in spite of the many uncertainties involved in trying to predict the net economics of doing so.
Rarely do I find such detailed and complete vindication for a position I've espoused as a matter of common sense from people who actually know what they are talking about!

Update 3:   as noted in this article in The Conversation by a couple of Australians, the IPCC is right to note that emissions cuts are about ethics too.  From the link:

Knowing the price of everything?

Judgements about value also come into the complex debate about future economic costs and damages from climate change.

All too often, analyses focus purely on the anticipated economic damage, using lower estimates as a rationale for less action on climate change. This is a simplistic view, as it misses three crucial points.

First, as humans we care about things that are not valued in economic markets. Most Australians care far more about the Great Barrier Reef than its (nevertheless impressive) tourism revenues would suggest. Most of us also care about species going extinct, on an emotional level quite separate from the environmental and health benefits of species diversity. Ignoring these concerns means ignoring many of the values that societies hold.

Second, climate effects will vary greatly across different regions and social groups, and this is usually not reflected in simple economic cost estimates. It is often the poor who are most at risk from climate change, and will find it harder to adapt or recover. If a citizen of an Australian beach suburb loses a A$2 million house, should this be counted as 200 times worse than a Vietnamese peasant losing their A$10,000 home?
Finally, and crucially, climate change is about risks. There is a risk – perhaps small, but we do not know how small – of catastrophic impacts. Should we ignore the risk of very bad outcomes for future generations, or should we give extra weight to them?

The IPCC’s report does not provide the answers, because the IPCC is not policy prescriptive. It aims to give decision-makers the latest reliable information, and a compass to navigate their way through decisions that should be based on deeper considerations than short-term economics or electoral tactics.

Rice issue

I didn't know that rice was a particularly problematic crop for picking up unwanted elements from the soil it's grown in.

Certainly sounds like excellent reason to always avoid Chinese grown rice, then...

Maurice does not have a clue

If ever there was proof needed that successful business men can be conned when it comes to science, Maurice Newman and his amazingly ignorant interview of last night provides it.

Basically, Newman seems to have read Ian Plimer's climate change denialism book and thinks it is the last word on climate science.   And, of course, Tony Abbott gets business advice from this guy.

The story of climate change denialism in the future history books will be about how a large slab of ideologically motivated people were conned for decades by a handful of contrarians, not even all of them being scientists (Monckton, etc).

George Brandis' silly complaint that "mediaeval' tactics are being used against climate change skeptics was equally nonsensical. 

I doubt I have seen a stupider Australian (Federal) government in my lifetime.  

Update:   the hard working Sou at Hotwhopper has a detailed take down of Newman's complete ignorance. 

Lead and crime; and somehow, Hitler and poo, too...

A good BBC magazine article looking at the claim that removing environmental lead has caused an international drop in crime over the past several decades.

I wonder if anyone has looked at the lead intake of international criminal Hitler?  Were his long standing illnesses consistent with lead poisoning?  As the article says:  "It causes kidney damage, inhibits body growth, causes abdominal pain, anaemia and can damage the nervous system."   He definitely had digestive problems, and certainly a shot nervous system at least in the last few weeks.

I just Googled "Hitler lead poisoning" and the first couple of pages don't have hits about it.  I doubt it would be true, but I am the first to make the suggestion?

Update:   I have previously blogged here about Hitler's chronic flatulence.  Just Googling now for articles on his health, I see this relatively recent post which is a fun read.  It notes the flatulence:
By the mid-1930s, Hitler was the ruler of Germany… and still farting like a horse.
but also adds this bit of info about the crank Dr Morell's medicine:
Morell served on the board of Hageda, a pharmaceutical company that manufactured a strange mediation called Mutaflor, whose active ingredient was live bacteria cultured from the fecal matter of “a Bulgarian peasant of the most vigorous stock.”

Mutaflor was intended to treat digestive disorders- the theory being that digestive problems were caused when healthy bacteria, which lived in the intestinal tract and were essential to good digestion, were killed off or crowded out by unhealthy bacteria. Ingesting the cultured dung of a vigorous, clean-living Bulgarian peasant, the theory went, would reintroduce beneficial bacteria into an unhealthy digestive tract and restore proper function.
Well, isn't it an odd thing that these days, doctors may well have tried a "fecal transplant" on Hitler using the poo of a healthy Bulgarian peasant, and it might have worked!  In fact, the Mutaflor idea was actually way ahead of its time, with just the delivery method being the problem. 

My conclusion:  we are lucky Hitler lived when he did and did not get a modern treatment that could have enhanced his health.  But on the other hand, would Hitler been the crazy man he was if he didn't have a regular painful gut?

I can see a science fiction movie in this - time travellers who seek to change the course of history via a surreptitiously delivered fecal transplant on Hitler.   (Of course, the highlight being the scene where some top Nazis investigate the noises coming from the bedroom, only to find a few men - our heroes from the future - attempting to insert the tube into the backside of an unconscious Adolf.  Can anyone suggest an appropriate line of dialogue for that scene, after the initial stunned silence?)    

[Update:  regardless of whether anyone has ever considered whether lead was in any of the medicines or diet of Hitler, I think I can be confident that no one in the world has previously had the idea in the last paragraph.  Isn't anyone going to give credit for originality? :) ]

Either from the edge of the universe, or the microwave in the staff common room

Arecibo Observatory Detects Mysterious, Energetic Radio Burst – Phenomena

(I'm not serious about the microwave being the problem, but the way.)

I don't remember reading about these extremely brief bursts of radio waves (apparently) from the far flung corners of the universe before, so it's an interesting read.  I see that one had been caught at Parkes radio telescope, too.  Why didn't they tell me that when I was visiting there at Christmas?

I would not have thought it possible

Teen stowaway survives flight from California to Hawaii in aircraft wheel well

Update:  a BBC article notes that most people who try this die, but there have been more survivors (and some over quite long flights) than I expected.

Having a good run

John Quiggin has a string of particularly good posts at the moment.  One on why he thinks small modular nuclear is going no where fast (you really have to wonder why, given vast experience with small nuclear reactors for ships and submarines);  the end of manufacturing in Australia (wherein he notes what I questioned as soon as I read Gittin's column last week - do we really call food manufacturing "manufacturing"?); and finally, a post against the tribalist Right and its tu quoque argument.

All really good reading, with many intelligent comments following.

Update:   By way of contrast, I wonder what I can learn from comments at that Right wing powerhouse of a blog, Catallaxy, today:



Update 2: More wisdom [sarc] from Catallaxy, this time from regular contributor Steven Kates, the Say's Law obsessive, from RMIT:
No one is uninterested in “the environment” and everyone wants to preserve the planet whatever that might mean. But global warming is so inane and so lacking in evidence that it separates those who have common sense from some kind of herd of conformity.

Butterflies have furry necks and hairy legs

So, I'm playing with the new, still pretty cheap, digital camera my wife brought back.  As I have said before, one of the best things about digital cameras is their ability to easily take macro - not to a professional standard, but to give good enough results for your average backyard photographer.

A butterfly just handily arrived as I was near the daisies:


This is from the version resized and sharpened on my computer.

I'll try uploading the unresized one to blogger and see what happens:


Not sure I can see much difference once Blogger has done its processing...

Anyway, here's a cropped shot from the unresized image (and added as "original size", even if it won't all fit in the column width.  Not bad what you get with 16 megapixels:

Blogworthy stories

*  The BBC notes one of the weirdest national fads ever:  Venezuelan women prepared to have silicone injected into their buttocks to make themselves more, er, attractive.
....the practice continues in spite of the ban. Up to 30% of women between 18 and 50 choose to have these injections, according to the Venezuelan Plastic Surgeons Association.

Men also get injected to boost their pectoral muscles, though the numbers are lower.
  The injections are made using a biopolymer silicone. The fact that this is injected freely into the body makes it more dangerous than implants, where silicone gel is contained within a shell.

The big attraction is that they are much cheaper than implants. An injection can cost as little as 2000 bolivares (£191, $318) and the whole procedure doesn't take more than 20 minutes.

But the risks are incredibly high.

"The silicone can migrate into other areas of the body, because it doesn't have any barriers. The body can also react immunologically against a foreign material, creating many problems," says Daniel Slobodianik, a cosmetic surgeon.
Extraordinary.

The Atlantic runs yet another story looking at why (American) conservatives won't support climate change policies, and blaming it on "framing".

I'm getting sick of this type of analysis, as it increasingly seems it is an exercise in excusing sheer bloody mindedness in a political wing which is determined to ignore evidence and scientific analysis on a major issue affecting not just them but the entire planet.  I mean, look at this chart from the article:

It is an indisputable fact that the scientific consensus has not changed over the decade of '02 to '12; the American (and Australian) right wing hostility to the issue is a factor of how their political culture has been played for the suckers that (a large part of them) are.    

*  Ross Douthat's initial take on Piketty is kind of interesting, even if not necessarily convincing.  I would have thought that Catholics who follow long standing Catholic social teaching would actually welcome Piketty's cautionary analysis.

*  In an essay from a Christian that probably contains a lot to annoy some atheists  (hello, JS), the ABC's John Dickson makes one point which I think particularly rings true:

Tip #8. Persuasion involves three factors

Aristotle was the first to point out that persuasion occurs through three factors: intellectual (logos), psychological (pathos), and social or ethical (ethos). People rarely change their minds merely on account of objective evidence. They usually need to feel the personal relevance and impact of a claim, and they also must feel that the source of the claim - whether a scientist or a priest - is trustworthy.
Christians frequently admit that their convictions developed under the influence of all three elements. When sceptics, however, insist that their unbelief is based solely on 'evidence', they appear one-dimensional and lacking in self-awareness. They would do better to figure out how to incorporate their evidence within the broader context of its personal relevance and credibility. I think this is why Alain de Botton is a far more persuasive atheist (for thoughtful folk) than Richard Dawkins or Lawrence Kraus. It is also why churches attract more enquirers than the local sceptics club.
Actually, now that I think about it, this analysis is also relevant to the earlier climate change issue, and suggests I shouldn't be so hostile to the "its all in the framing" argument.   I would be if it weren't the case that those promoting the "framing" towards inaction is actually actively promoting disbelief in the objective evidence.

Ugliness, and beauty, at Easter

So, on Friday night I was home alone, deciding what to watch, when the well reviewed Clint Eastwood movie "In the Line of Fire" started on free to air TV, and I half watched the opening sequence while trying to find a DVD.

Sure enough, within 10 minutes there's been a pistol clicked at someone's head, a hostage with a plastic bag over his head is roughed up, and Eastwood blasts away a couple of (I assume) bad guys at close range in the room in graphic detail as if it was another day in the office.

I thought it was just typical of this guy's shtick.

And in case you didn't know already:  man, I just hate the guy's oeuvre - ugly, usually revenge themed, graphically violent and violence endorsing* junk, featuring an actor with a range from 0 to 1 if you're using a scale that goes to a hundred.   (And in recent incarnations, usually with lots of swearing too.)    As far as I am concerned, he's been a poisonous amoral stain on cinema, in fierce competition in my mind with Quentin Tarantino as to which modern film maker ranks highest in my contempt.   

Obviously, I did not continue with that film, and found the DVD of the recent science fiction film Looper that I was looking for.   (I bought it as an ex-rental for $2, as I was not completely confident that I would like it, but hey it got a very high rating on Rottentomatoes.)

Well, what a mistake that was.

I didn't mind the surprise element within the first few minutes when you see what "loopers" do - wait at the designated spot for a person being sent back from the future for immediate execution with a futuristic shotgun.  (It's the speed with which it happens that sort of shocks, and this first one is not shown in graphic detail.)

But that was the last indication I had that I might enjoy the film.

The thing that kept coming into my mind was how intensely ugly this film is.   Everything from Joseph Gordon-Levitt's face done up (with no success whatsoever, if you ask me) to look like a young Bruce Willis, the depressing future society portrayed (everyone packs a gun and uses it more or less casually, it seems, and drug addiction seems rampant - now that I think of it, it's probably pretty much how a libertarian led future would look), the entire stupid story set up, to the increasing level of violence as the movie progresses and continual profane dialogue.

Honestly, the whole scenario is pretty stupid and bizarre, and if I could make a guess, just seems to have been contrived to serve one idea pitched at some studio execs - a younger man has to fight the future version of himself. It has elements that I could see serve no real value at all (the bit about the future development of telekinesis in some people, for example.)

Now, I was so appalled by the bleak amorality of the entire exercise (not just the movie story, but the fact the movie was made at all) I could not really be bothered analysing the time travel contrivances for consistency.   But others have (in fact, many reviewers noted that they doubted that it was logically consistent), but one reviewer did a particularly good job at complaining how it was nonsense, even by the loose standards one has to bring to this genre.

I have no idea at all why it got good critical reception, and the fact that so few critics reacted against its bleak and violent nature just shows what a boiled frog in the pot of declining values, so to speak, the collective body of professional cinema critics has become.

So what could redeem the weekend?

Well,  I had another ex rental DVD I had been wanting to watch, and last night I did:  Terrence Malick's The Tree of Life.

This is an intensely beautiful work that I cannot recommend highly enough.

Certainly it's not a movie with any normal narrative; it's more an impressionistic contemplation of Christian theodicy that imitates how human memory really is experienced in an extraordinary way.

It's almost hard to fathom how it was made  - there are so many very short sequences you can't imagine it being scripted in any normal sense.  (I should go looking for interview with Malick about this, but I suspect he might have shot a huge number of scenes and the movie was really created in the editing room.)

The overall thrill of the thing is how so many beautiful images are blended together in a very kinetic way.   The camera is virtually never still; it swoops around but gracefully and never to jarring effect.  It enhances the half dreamlike quality of memory that the film captures so perfectly.  And I say that as someone who does not like the overuse of handheld camera in modern cinema, particularly action films.

Now, it is not at all clear what some sequences, particularly near the end, mean.  You are left with the feeling that main characters have reached resolution, but exactly how or why is not at all clear.  But hey, that is in a way one of the films features - I don't think there has ever been a movie more inviting for a re-viewing than this one.

And it is, in its way, a near perfect film for Easter (at least for those of a religious persuasion).

After Tree of Life finished,  I remembered that SBS was showing Mel Gibson's Passion of the Christ.  I have never seen it - there were too many reviewers complaining of the near pornographic nature of the violence to encourage me to see it.   And indeed, as I turned to the channel, Jesus was on the cross, dying, and the soldier stabs his side with a spear and gets, not just blood and water flowing out as per scripture, but something like a brief fire hydrant effect.

It looked completely ludicrous, and hence I was at least satisfied that a 60 second viewing confirmed I should never bother with the film in its entirety.  (I have never cared for Mel Gibson and his movies either - but he is no where near as far down on my list of Hollywood loathing as Eastwood.)

And finally, my family arrived back from their trip overseas today, safe and sound, and that's a thing of beauty in itself...

 
* Yes, I am aware of the plot of Gran Torino.  My comment stands.

Important parapsychology news

Back in 2010 I posted about the remarkable parapsychology experiments of Daryl Bem which seemed to establish a small but consistent effect of precognition.   The experiments were very clever, and rather odd in many respects.  (The most successful one involved guessing behind which curtain was an erotic photo!  But I guess testing for precognition is always going to feel weird.)

In 2012, I noted that one attempt at replicating the experiments had failed.  (See, I am very fair.)

Now, Dean Radin reports that there has in fact been many experimenters who have had successful replication.

The full paper pre-print detailing this can be downloaded from here.  Although the statistical analysis talk is hard for a lay person to follow in full detail, the conclusion of successful replication seems very clear.  The paper's background discussion, and its concluding sections about implications for future science research, make it a very interesting read.

I guess one has to wait to see what the skeptics have to say about this (Radin is pessimistic they will ever be convinced), but this appears to me to very significant.

Update:  the original experiments were hotly contested by skeptic types, and early failure to replicate were treated as dismissing it all.  Bem himself spoke about the debunkers here.  

Tobis on the likely El Nino

Michael Tobis has his own take on climate change which I have always found pretty convincing (he has always emphasised "weather weirding" as being an important sign of climate change), and his recent post on the likely El Nino of later this year is an interesting read.

(Another idiosyncratic take on matters by MT is that he doesn't like the "redefining" of global warming to include ocean warming.  That seems a rather odd position to me.)

Anyway, he is betting that  the El Nino will (finally) lead to a globally hotter year than 1998, which will be followed by persistently hotter years as a further "step up" in the process of global warming.  This is pretty much what is needed to finally shut up and (further) marginalise the denialists.  They already are marginalised scientifically; what is needed is their marginalisation politically.

Incidentally, I just stumbled across in my old magazine collection (I am being put under pressure to thrown them out - I am resisting) a January 1986 Discover cover story on global warming.   Apart from the sensationalism on the cover (questioning whether New York would be more or less flooded by the 2030's), a quick peruse of the article itself shows that the scientific view and warnings (and appreciation of uncertainties) has been remarkably consistent since that time.   I have also read much of Stephen Schneider's book "Science as a Contact Sport", which gives a good background as to how science developed its concern about the topic, and one interesting point he makes is that Lindzen from the start was a skeptic about it being a problem.

Perhaps I should scan the Discover article and link it here one day, so people can see how fair it was.

Mining methane

BBC News - Methane hydrate: dirty fuel or energy saviour?

The article looks at the question of whether mining methane hydrates would be a good idea, or not.  One thing it doesn't mention is what sort of benefits could come from the widespread use of methane for fuel cells, rather than burning it.  I would like to know what difference that would make.

Update:  interestingly, via the link in the last paragraph, you can get to a Tim Worstall post about fuel cells, about which he seems to know quite a bit.  His conclusion:
My basic belief about solid oxide fuel cells is that they’re going to be the technology we all end up using. No, I don’t know the precise technology, rare earth, scandium, bismuth, that will win out in the marketplace. But my operating assumption is that wind and/or solar to the electrolysis of water to produce hydrogen which is then stored to be run through a solid oxide fuel cell is the basic answer to future energy needs.
Carbon pricing to make that happen faster would help, no?

Give this man another job

Public bathrooms and homophobia: why are men afraid to pee together?

Am I the only person who finds Slate gay editor J Bryan Lowder consistently annoying?

I think it's rubbish to suggest that the majority of (male) paruresis is due to homophobia.  I very much doubt it has anything to do with the perceived sexuality of the unwanted observer for any sufferer. It's just a self feeding loop of "performance" embarrassment, I reckon.  (Years ago here, I noted my own - relatively mild - case being instituted by ridicule by a couple of older students in primary school.)

I'll also repeat my point that I think it is pretty easily relieved for many men by inexpensive bathroom design for simple privacy screens between the individual urinals that are now standard in public toilets.  I still puzzle why architects, or whoever it is comes up bathroom designs for new buildings, do not recognize the benefit of that simple feature.
