Musician's death noted

Ric Ocasek's death gives me the opportunity to note that I enjoyed The Cars in the 1980's:  fun, catchy pop that I may still have on vinyl in a cupboard at home.    He was a bit of an odd looking dude, though; but then again, I suppose a lot of pop/rock stars of the era were not exactly handsome.

Not sure what difference Bolton leaving has made, really...

Yes, this is a ridiculous way for a President to act:

Update:  more Twitter commentary on the matter:

"It belongs in a toilet"

Has this story flashed around the innerwebs yet?   I saw it via a Dave Roberts tweet this morning:  a link to this very important update to archaeological science:

Experimental replication shows knives manufactured from frozen human feces do not work

You can read the full article at the link.  A highlight or two:

Fecal samples were formed into knives using ceramic molds, “knife molds” (Figs. S1–S2), or molded by hand, “hand-shaped knives” (Fig. S3). All fecal samples were stored at −20 °C until the experiments began...

Neither the “knife mold” samples, nor the “hand-shaped knives” could cut through hide (Figs. S5–S6). Despite the hide being cold from refrigeration, instead of slicing through it the knife-edge simply melted upon contact, leaving streaks of fecal matter (Fig. S4).

I have even downloaded the supplementary material so you can see what a frozen human poo blade failing to cut looks like.  Here:

And now I have no idea how to end this post appropriately...

Explaining the Many Worlds, again

Sean Carroll has a new book out, promoting the Everett Many Worlds theory as being correct even if (to say the least) counter-intuitive, and so there is some good reading about it around the 'net.

First, Carroll's own essay at Aeon gives a nice, pretty clear account.  Well worth reading.

Secondly, the book must be pretty good, because fellow physicist Bee Hossenfelder gives it a good review at Backreaction.

And finally: another good review at NPR.

Update:   Peter Woit liked the book, but is very annoyed that Sean Carroll is participating in some nonsense descriptions about what Many Worlds means.

The Orwell failure

Oh look - a really long essay about Orwell and 1984 in particular, which I think gives plenty of ammunition to my unpopular but resolute position that the book is vastly over-rated and actually a failure on most levels.

My only regret is that I did not have stuff like this to bolster my dislike of the book in high school.

Living Dutch style

I have never been to the Netherlands, and didn't understand how some of their "let's live well below sea level" worked for much of the country until watching these interesting videos from Channel News Asia this morning:





What's that breed of cow in the second video, by the way?  They are very pretty looking, for cows.

Highly regarded movies I didn't much care for

I caught up with the 1995 Michael Mann film Heat for the first time last night.  (It was a cheap hire on Google.)   While it was sort of amusing watching Al Pacino play a cop who seemed potentially more dangerous (and nuttier) than criminal mastermind Robert De Niro, I don't think the film had all that much going for it.  One big shoot out on the streets of LA isn't enough.   That bank heist before it seemed way, way too easy.   A lot of the dialogue was hard to follow - you more or less just had to hope that it would become clearer in the next scene what they had been talking about in the one before. My son said it reminded him a lot of playing Grand Theft Auto, and I think he is right. 

Anyway, not the pits, but not that great either.

A few weeks ago, we watched Birdman or (The Unexpected Virtue of Ignorance).  Technically well made, with the long, long single tracking shots; its basic theme of "you have to be nuts to want to be actor" is a tad self indulgent in just the right way to win critics' praise and Oscars, but is not of that much interest to the rest of us.   And does Edward Norton ever get to play a normal human?

Again, not the pits, but...etc.

I'm finding it a bit difficult, lately, to find streaming service movies which have I have missed and really like when I do get to watch them.

 

Shadow self

Happens to a lot of blokey blokes, it seems

Jack the Insider, the ever genial blokey writer, says today (in relation to the apparent suicide of that ex footy player) that he too has had periods of suffering from suicidal ideation.  He writes:

...for many years, suicide ideation was like an unwelcome houseguest I couldn’t get shot of. The demons of anxiety, panic and desolation mutter away. “I’ll never be any good.’’ “I’m letting everyone down.’’ Combine that dark mantra with a sleepless couple of nights and you’re in the danger zone, borderline psychotic, suffering silently from a pain that won’t go away.

Some people still cling to the atavistic notion that suicide is for the weak. It’s not. It can’t be. It is almost the hardest thing anyone can do, bearing in mind the hardest is to survive and live on.

Mental illness is, if not invisible, then something sufferers are adept at camouflaging. It hides in plain sight. There are no ugly blemishes or boils, no hacking coughs, no greying of complexions. It is almost impossible to see in others.

I’ve spoken on live television. I’ve spoken at venues where audiences that number from fifty to five thousand. I flick the switch to the wisecracking good bloke, that part of my personality that people expect to see. I do it easily and without any reservations. I like that part of me, but I know it is a disguise.

Well that's very clear, direct writing on the topic, if a little worrying in its warning that it can be impossible to tell if someone is suffering this way.   (On the other hand, I suppose, it could be seen as comforting for those who blame themselves after a suicide for not noticing.)

He also says this:

Beyond mental illness the one thing they shared with Frawley was a personality type. They are characters who everyone wants to be with. Larger than life, the lives of the party. I often wonder if there is some correlation between that personality type and frequency of mental health problems.

It could just be more my personality than any particular insight I have into other people, but it's fair to say that I have always felt that I do not want to be around "life of the party" types;  perhaps due to a sense I've instinctively had that brashness can too easily be a cover for inner dissatisfaction?

Either that, or I just dislike other people having too much fun. :)
 
Also on this topic, I noticed on Twitter this thread by some people complaining about RU OK day - many saying that they had suffered mental health issues and they did not enjoy the day at all, thinking it was shallow and a patronising take on a problem which lasts all year, not just one day, etc etc.

To be honest, even allowing for their problems, this annoys me.   Any "day" which intends to promote awareness or raise money for research can annoy people affected by the illness.   I'm sure I read once that parents who have lost a baby to SIDS can find the "red nose day" a distressing reminder of their loss.  I can understand that, at least for the first few years after their baby's death. 

But really, you have to allow for the greater good that such promotions may achieve, and the good intentions of the people who create such awareness of a health issue.  

Sure, have a whinge about the lack of readily accessible mental health services, if that is something you know about, but don't get upset at a program that can do some good.

From (old) cinema to reality (almost)

The internet makes it easy to remember things now.

This story:

 Cockpit coffee spill forces commercial jet to make emergency landing 

put me in mind of an old movie that I probably watched as a kid one Saturday afternoon on the black and white TV about a plane crash where it turned out to have been caused by spilt coffee.

And the internet reminds me - the movie was Fate is the Hunter.   A very dramatic noir-ish title, for a plane crash movie, no?   About the only thing I remember about it is the coffee spill revelation at the end.   Obviously, modern pilots need to watch more old movies.

The ridiculous Right

Not a bad, short column here about the utterly ridiculous Tucker Carlson saying that he's glad John Bolton has gone, because he was a man of the Left:

"It is great news for America," as Fox News host Tucker Carlson said Tuesday evening, "especially for the large number of young people who would have been killed in pointless wars if Bolton had stayed on the job." Bolton was an inveterate hawk, perpetually undermining the president's better instincts on pursuing diplomacy and extricating America from her many misadventures in the Middle East. And anyway, as Carlson continued, Bolton "fundamentally was a man of the left," and — wait, what?

John Bolton, fundamentally a man of the left? Opposed to abortion and gun control, pro-private sector remedies to recession, unrelentingly aggressive on foreign policy John Bolton? Bomb Iran and invade North Korea John Bolton? Supporter of Barry Goldwater; member of the administrations of Ronald Reagan, George H.W. Bush, George W. Bush, and Donald Trump; Fox News commentator John Bolton? That John Bolton?

As she explains:

Some conservatives are putting in the difficult but necessary work of constructive criticism of their own movement. But Carlson and others like him have chosen the easier and more damaging method of handling disagreement via a constant game of "no true Scotsman." Instead of admitting fault, error, or even simple differences of opinion within their own camp — and different policy preferences unquestionably can develop from a set of ideological underpinnings unified enough to fund a single movement — they relabel anything objectionable as the property of their political enemies.

For this crowd, to have a bad position is to have a liberal position. If you're not with us, you're against us. To err is to be a Democrat. For Carlson, if Bolton is a disaster on foreign policy, that proves Bolton is a left-winger.

Yet more "what climate change looks like"

From The Guardian:

Parts of eastern Spain received what in some places was the heaviest rainfall on record on Thursday, as storms wreaked widespread destruction and killed at least two people.

The regional emergency service said a 51-year-old woman and her 61-year-old brother had been found dead in an overturned car that floodwaters had washed away in Caudete, about 60 miles (100km) south of Valencia, the private Spanish news agency Europa Press reported.

While on the topic of increased floods from climate change, a recent study at Nature confirmed that climate change is both increasing floods in parts of Europe, and decreasing them in other parts:

Our results—arising from the most complete database of European flooding so far—suggest that: increasing autumn and winter rainfall has resulted in increasing floods in northwestern Europe; decreasing precipitation and increasing evaporation have led to decreasing floods in medium and large catchments in southern Europe; and decreasing snow cover and snowmelt, resulting from warmer temperatures, have led to decreasing floods in eastern Europe. Regional flood discharge trends in Europe range from an increase of about 11 per cent per decade to a decrease of 23 per cent. Notwithstanding the spatial and temporal heterogeneity of the observational record, the flood changes identified here are broadly consistent with climate model projections for the next century^4,5, suggesting that climate-driven changes are already happening and supporting calls for the consideration of climate change in flood risk management.

Of course, this will cause simple minded, dumb people, like Bolt, Blair and anyone at Catallaxy, to have a headache, because they cannot conceive that climate change is not exactly the same in every part of the world.

Vaping taking the big hit

I wonder if vaping JC from Catallaxy invested in some vaping company's shares?   Or if he is still vaping himself.  Because businesses involved in this activity must be taking a severe hit in sales, one would imagine.  From People magazine:

A student athlete still has difficulty climbing up stairs after being hospitalized with “severe lung damage” caused by e-cigarettes.

“My lungs were that of a 70-year-old’s,” Illinois teen Adam Hergenreder, who started vaping when he was 16, was told by the doctors, according to CNN.

Following days of persistent nausea and vomiting, the teenager was hospitalized in late August, where doctors were able to realize the full extent of the damage....

“If I had known what it was doing to my body, I would have never even touched it, but I didn’t know,” the teen said, adding that “it was scary to think about” the damage “that little device” did to his lungs.

After being released from the hospital, Hergenreder still finds it “difficult to even do normal activities, like going up stairs,” which leaves him winded. His future with sports is also in jeopardy.

“I was a varsity wrestler before this and I might not ever be able to wrestle because that’s a very physical sport and my lungs might not be able to hold that exertion,” he told CNN. “It’s sad.”

I did try to warn you, JC.   

Playing with rats for a living

It's been a while since I had a rat post, but this story in The Atlantic about researchers who taught rats to play hide and seek (with the only reward being to tickle them) is quite charming:

All six rats learned to seek, and five also learned to hide. They clearly understood the rules of the game, and played strategically. When seeking, they searched systematically, beginning with past hiding locations. When hiding, they chose opaque boxes instead of transparent ones and kept quieter. They also seamlessly switched between the two roles, taking their cue from whether the starting box was closed (indicating “seek”) or open (indicating “hide”).

The rats learned the game in only a couple of weeks, which is “impressive in neuroscience,” says Juan Ignacio Sanguinetti-Scheck, who also took part in the study. “Animals can take months to learn tasks, even monkeys, but we’re generally trying to teach them to use joysticks or things they’d never do in normal life.” Hide-and-seek, by contrast, draws on behaviors such as concealing, finding peers, and switching roles, which aren’t just natural parts of rat life, but also frequent parts of rat play. In retrospect, it was the perfect game for uniting two different species. “It’s a clever and innovative approach,” says Gordon Burghardt of the University of Tennessee. “Many animals play with other species and engage in peekaboo, tug of war, or tag, but this example does seem unexpectedly complex.”

Why did the rats play along? It’s possible that they were going after tickles and other social rewards. After all, for two decades researchers have known that rats enjoy being tickled and react by producing ultrasonic chirps that can be compared to laughter. But Reinhold found that once discovered, the rats would often run away and re-hide, delaying their reward and prolonging the game itself. “It seemed really playful,” she says.

She and her colleagues believe that rather than pursuing rewards, the rats were playing for the sake of it. They played because they had fun. For a start, and this is an unusual but welcome line to see in a scientific paper, “the animals looked like they are having fun,” the team writes. When they reunited with Reinhold, they frantically jumped on the spot—a behavior delightfully known as freudensprung, or “joy jumps.” They also teased Reinhold by repeatedly getting close and running away.

Wall Street not what it was

I hadn't read of this before (thanks, ABC):  Wall Street is not what it was, with investment banks moving out into other parts of New York and their former building converted into apartments:

When you walk down Wall Street today, it's all condos", says Brian Barnier, director at ValueBridge Advisors.

"JP Morgan's office building — that's condos.

"Somebody's got a bathroom where JP Morgan's [John Pierpont "Jack" Morgan] office was."

Wall Street real estate agent Julia Hoagland is selling rentals on the strip.

"Wall Street and the financial district have changed dramatically in the nearly two decades since September 11," she says.

"A healthy housing market and tax incentives motivated developers to convert commercial buildings to the more valuable residential product."

The former AIG tower across the street from the NYSE and JP Morgan was made into rental apartments.

The owners of 60 Wall Street, which housed Deutsche Bank, have reportedly commissioned CBRE to market the tower's 1.7 million square feet of office space to apartment developers.

It also discusses changes in the whole investment banking line of business:

Mr Barnier, who has first-hand experience working in investment banking as an independent consultant, says the industry has traditionally leaned on three main sources of revenue.

Buying and selling companies, which was a major theme of the movie Wall Street, is one source of revenue. Much of this business has dried up.

Another huge revenue stream for investment banks has been their corporate advisory services.

"And they're now getting more competition from the consultancy firms." Think the big four accounting firms: EY, PricewaterhouseCoopers, KPMG and Deloitte.

"They're shedding traders right and left, going more to algorithmic models [where computer-driven mathematical models buy and sell shares based on stocks meeting certain criteria]."

"Each one of those business lines is under a lot of pressure."

Heh, again

From the Onion.

But what does it all mean?

At the New Daily, there's a story about the increase in government debt, and the uncertainty as to where it all stops.

Take this illustration from it:

As far as Australia is concerned, our debt government debt level is apparently at 41% of GDP, which (assuming debt is not a good thing) sounds pretty healthy. 

And what about this chart:

As for us:

Australia is a notch ahead of the US, with a corporate debt-to-GDP ratio of 74.7%.

As far as I can tell, the problem is that no one really understands the economics of debt on a global scale.

The thing Australia is "bad" at is household debt to GDP:   we rank near the top at about 120%, whereas the US is about 75% and China 52%.  But having a really low level is not a sign of a country you would like to live in:

So, all rather confusing as to what it means, really...

A victim of the culture wars

The Catholic Herald has an article entitled The Church used to have a powerful economic voice. What went wrong? and that is a pretty good question.

It starts:

One hundred years ago, the National Catholic War Council, the predecessor of today’s US Conference of Catholic Bishops, issued a “Program for Social Reconstruction”. Drawing on American progressive thought and the encyclical Rerum Novarum (1891), it argued for a living wage, urban housing, trust-busting, worker-run cooperatives, and employee ownership of industry.

Unlike most documents issued by America’s Catholic bishops, this one gained widespread notice. It was denounced by some as socialistic, though it in fact condemned socialism in unsparing terms. Leo XIII had done the same in Rerum Novarum. Then as now, a great deal of confusion arose from the fact that the Catholic Church condemns socialism while advancing ideas many people falsely regard as socialist. Some Catholics (including this author) who reject what the Church rejects have even called themselves socialist in this colloquial sense, with more exuberance than accuracy.

The statement’s ideas, some more practical than others, were not immediately implemented. But they helped shape the arguments and activism that would later result in the New Deal and the Great Society. The priest who drafted the statement, Fr John A Ryan, became an influential supporter of Franklin Roosevelt. The Program remains the most important intervention the American bishops have made in economic debates.

Given the document’s importance, the American bishops have marked its centenary rather tepidly.

These paragraphs offer an explanation: 

 Looking back on the document now, a right-wing observer is likely to view it as too economically progressive, and a leftwing observer is likely to view it as culturally retrograde. For example, the bishops state that women should receive equal pay for equal work, but that only adult men are to be guaranteed a living wage (the idea being that the man is responsible for supporting the family). They ask that women be treated fairly – in the name of justice and chivalry. Yet they insist that “the proportion of women in industry ought to be kept within the smallest practical limits.”

Not all these statements necessarily follow from Catholic premises. But simply glossing over them (as many left-wing admirers of the Program do) obscures something important about the document, however questionable some of its conclusions may be. Its signatories felt it was natural to argue simultaneously for economic justice and for healthy families (as they understood those things). They did so in a way that offends liberal economic and cultural pieties. Their statement showed an unabashed confidence in Catholic thought, economic and moral, that has since been lost.

This loss of confidence has much to do with developments in post-war politics. The Left focused on cultural deregulation and the Right on deregulation of the economy. It is hard for the Church to support unions when unions support abortion. It is hard to endorse the pro-life party when its members deny the universal destination of goods.

It is no secret that both political parties have become alienated from the working class. Hillary Clinton’s denunciation of “deplorables” and Mitt Romney’s misleading dismissal of “people who pay no income tax” were of a piece. Though it has generally avoided such crude rhetoric, the Church has suffered the same fate. Poorer and wealthier Catholics used to attend Mass at roughly equal rates. But there has been a large drop in attendance among working-class Catholics born after 1960. It should not surprise us that the Church has lost its economic voice at the same time it has lost the attachment of the working class.

One of the most appalling features of conservative Catholics is their adoption of  selfish, small government economic policies of the libertarian Right, and pretending that this has always been true Catholic thought.   And a large part of the reason for this is because they don't want to catch culture war cooties by being seen to be aligned in any way with the Left on the matters of abortion and sexuality. 

Yet more reason not to vegan

An article at The Conversation talks about a recent UK study indicating that vegetarian/vegan diets are associated with a higher risk of stroke (but a lower risk of heart disease.)

The article seems very reasonable, and it notes that some researchers think a lack of vitamin B12 might be behind this:

They cite a number of Japanese studies which have shown links between a very low intake of animal products and an increased risk of stroke.

One nutrient they mention is vitamin B12, as it’s found only in animal products (meat, fish, dairy products and eggs). Vegan sources are limited, though some mushroom varieties and fermented beans may contain vitamin B12.

Vitamin B12 deficiency can lead to anaemia and neurological issues, including numbness and tingling, and cognitive difficulties.

The authors suggest a lack of vitamin B12 may be linked to the increased risk of stroke among the vegetarian group. This deficiency could be present in vegetarians, and even more pronounced in vegans.

But this is largely speculative, and any associations between a low intake of animal products and an increased risk of stroke remain to be founded in a strong body of evidence.

A veganism worry

As I have said recently, the apparent triumph of veganism over vegetarianism bothers me, because you read so very often how certain key nutrients are hard to get from plants only. 

Here's another one to add to the list:

The momentum behind a move to plant-based and vegan diets for the good of the planet is commendable, but risks worsening an already low intake of an essential nutrient involved in brain health, warns a nutritionist in the online journal BMJ Nutrition, Prevention & Health.

To make matters worse, the UK government has failed to recommend or monitor dietary levels of this nutrient -- choline -- found predominantly in animal foods, says Dr Emma Derbyshire, of Nutritional Insight, a consultancy specialising in nutrition and biomedical science.

Choline is an essential dietary nutrient, but the amount produced by the liver is not enough to meet the requirements of the human body.

Choline is critical to brain health, particularly during fetal development. It also influences liver function, with shortfalls linked to irregularities in blood fat metabolism as well as excess free radical cellular damage, writes Dr Derbyshire.

The primary sources of dietary choline are found in beef, eggs, dairy products, fish, and chicken, with much lower levels found in nuts, beans, and cruciferous vegetables, such as broccoli.

It doesn't say how it affects "brain health" - but it's a worry that it is important for fetal development in particular.   I hope there is no risk that more widespread veganism will end up dumbing down the population overall.
