A strange version of dementia

Younger onset dementia - Health Report

Here's an interesting article which deals with a type of dementia I hadn't heard of before: young onset frontotemporal dementia:

John Hodges: Frontotemporal dementia means it's affecting the frontal lobes predominantly and the main hallmarks of that are personality change and language deficits, which we call aphasia.

Lynne Malcolm: Give me an example of the sort of behaviour that might present in frontotemporal dementia?

John Hodges: Becoming socially inappropriate, saying embarrassing things, the type of things one might think but not say. You know, meeting somebody that you haven't seen for a long time and saying 'oh, you've put on a lot of weight,' or, you know, 'you're very fat since I saw you last time.' Or often rather sexually disinhibited comments, particularly the men, which is usually put down to, oh well, you know, one too many drinks. Because part of this disinhibition is that people often do start to drink too much alcohol. Problems with judgment, often making unwise decisions, becoming very gullible to scams and losing a lot of money, making bad investment choices, these are all symptoms that are related to us by families that we see.

This range of symptoms mean that the cause is often not recognised for some time. Instead, depression is usually first suspected. So what are the early signs?:
John Hodges: Well we don't want an outbreak of everybody with a little bit of an occasionally inappropriate thing being thought to have frontotemporal dementia, but I think a persistent change in character. I mean the one thing the families say about people with frontotemporal dementia is, you know, 'they are no longer the person they used to be. There's been a real change in their empathy and judgment.' So I think that's a very important hallmark.
And it turns out that a difficulty with understanding sarcasm is part of it too.

I wonder to what exact there is a degree of self awareness of the personality changes in the early stages.

Overall, a very unusual disease.

In other dementia news: playing a game in which you stand a good chance of repeated concussion is not a good idea.

Another Andy still alive

Andy Williams accuses Barack Obama of following Marxist theory

The only reason I link to this is because of my surprise that he is still alive. It's the same type of surprise I had last year when Andy Griffiths turned up still looking sprightly too.

Andy's face is looking suspiciously smooth, if that's a recent photo.

Different approachs

Scrubbing the Atmosphere - TierneyLab Blog - NYTimes.com

Apparently, an article in Science notes that research into technology to remove CO2 from the atmosphere is not getting government funding, but it may be able to make an economical contribution to the problem. Unfortunately, the article itself seems to be behind a paywall. (Is it about time that the science journals made all papers relevant to AGW and ocean acidification free to the public, as their contribution to public education on the topic?)

Another thing: a couple of year ago, I noted that there were a couple of suggestions on the 'net that CO2 from power stations could be turned into solid sodium carbonate. You would not have the problems associated with pumping liquid CO2 into the ground.

Is that idea completely without merit? Is that why we never seem to hear about it?

Not all ice after all

In my absence, I didn't get to mention how surprisingly pretty Iceland in summer looked in last week's Foreign Correspondent. It has grass and meadows? People swim there in summer? Who knew?

A question of maturity

Coming Out in Middle School - NYTimes.com

I haven't yet spotted any conservative comment on this lengthy NYT Magazine article about the increasing phenomena in America of very young adolescents "coming out" during Middle School, so I'll have to make my own.

The article is written by a young gay journalist who, while apparently very supportive of gay youth, does at least admit to some surprise that kids at that age (the article mentions mainly from 10 to 14 year olds) should be so confident of knowing or understanding their sexuality.

Indeed. Apart from the girl who decided she was bisexual at 10, and apparently went on a "date" with a girl soon after, if you read some of the conversation that goes on as a few young folk take the journalist around their Middle School, you get a strong sense of the teenage immaturity on display:
All three were members of the school’s G.S.A. “Even though this is a liberal area,” Alison explained, “it’s still hard to be gay at this school. Most people won’t even come to G.S.A. meetings because they don’t want people other than their close friends to know they’re gay or lesbians, even though straight people also come to meetings. I get called a lesbian all the time even though I’m not.” She continued, “People are totally paranoid.” She suggested that they “come up with some code words on the down low so we can tell you what’s up without anyone knowing what we’re saying!” (They settled on “paw” for gay and “woof” for bisexual.)
Hmm. Already we seem to have a couple of 12 year olds with an unhealthy, gossipy interest in other's sexuality, and resenting the fact that some other students resist the idea of being "out". Let's see how this pans out:

As we walked past the gym, a group of boys came rushing out. Justin pointed to a short, muscular eighth grader in a baseball cap. “Paw!” he said.

Alison looked surprised. “Isn’t he a woof?”

“No, he just thinks he’s a woof,” Justin said.

Amelia looked confused. “What does woof mean again?”

A minute later, they fixed their gaze on a boy sitting against a wall listening to his iPod. “Paw,” Alison told me. “I mean woof!”

“Yeah, he’ll make out with anyone,” Justin confirmed. “Totally bisexual.”

“No, he’s not!” Amelia said, apparently distraught by the news.

“Oh, stop getting all mad just ’cause you like him,” Alison told her. “Everyone knows he’s a woof.”

After pointing out a handful of girls who are “definitely woofs,” Alison turned to me and recalled a recent “lesbian moment” of hers. “I totally had the hots for this girl in ‘Jesus Christ Superstar,’ ” she said with a giggle. “I was, like, ‘Whoa, I’m really attracted to you right now!’ ”

“Jesus was hot in that, too,” Justin offered.
(Odd that the last comment was left in, given the ire it will raise in some Christians.) But further down:

As we came to the end of our tour, we approached a handful of boys sitting in a circle on the pavement eating lunch. “Woof, woof, woof, woof, woof!” Justin said, barely able to contain himself. “They’re all woofs.” One boy heard him and turned to us. “What’s a woof?” he asked us.

“Never mind,” Justin said.

“I don’t think he’s really a woof,” Alison told me, referring to a boy in the circle. “I think he’s straight but just confused.”

“He’s not confused,” Justin assured her. “Hes confused,” he said, referring to another boy in the circle. “He doesn’t know what he is. He changes his mind a lot.”

I was certainly confused trying to keep track of it all, but Alison told me not to worry. “We can’t even keep up with who’s gay or bi and who’s into who, and we go to school here!” she said.
Are we supposed to feel good that there is an large support group movement (the GSA - Gay Straight Alliances - which are popping up in many American Middle Schools) for youngsters like this who spend their time assessing every passing person's sexuality? Justin, who I assume we are to believe is a gay boy in need of support, comes across as a pretty offensively immature individual who is happy to engage in exactly the type of labelling that is at the heart of "straight" bullying of "gays."

I'm not alone in finding the article doesn't exactly do some of the kids any favours by quoting them so clearly:
I have no doubt that the author meant to champion their pride and their cause, but along the way, certain passages (and especially quotes) come off as glib and disrespectful of the kids’ views of sexuality, magnifying their immaturity and forwardness for impact and humor.
If you ask me, the goal of preventing bullying (a worthy enough thing of itself) has swung way too far in the other direction if it is encouraging kids in the pre-teen to early teen range to concentrate on their sexuality, of whatever kind, at that age. Effective and strict rules against bullying on any grounds, including sexuality, should not be that hard to teach and enforce, surely, without the need for groups that seemingly encourage pre-pubescent sexuality self-analysis. The article, perhaps inadvertently, supports the concern that many kids simply do not at that age have the maturity to usefully engage in, or act upon, that sort of self analysis.

Week end catch up

I haven't posted for a week, but the lure of the internet remained too strong to resist. Here are some stories I would normally have posted about:

* What on earth does it take to get Channel Nine to sack Sam Newman? I'm appalled that there aren't enough people appalled by his recent, absolutely 100% offensive "monkey" comments to achieve the end of his career. What is wrong with the people of Melbourne in particular?

* Slate ran a review of a new book on "Greek Love" and suggested that it contained lessons for the current gay marriage debate:
In short, there was no single "traditional" way to conduct same-sex relationships in ancient Greece. This fact in itself might make us leery of any claims about what a "normal" or "traditional" domestic setup might look like. Love comes in many guises and gets culturally legitimized in many ways, and that has been true since antiquity. Any claim about "the way things have always been" is liable to be false.
Hmm. The only thing overlooked is that same-sex relationships have historically been "culturally legitimized" in "many" ways except marriage. See, it's not just old fuddy duddy conservative Christians saying gay marriage makes no sense, even the pagans were on side with that one.

* Let's not get overly excited about the reports of water on the moon. The quantities are not big:
So far, the water does not appear to be very abundant – a baseball-field-sized swathe of lunar soil might yield only "a nice glass of water", Pieters told New Scientist.
I'm still pinning hopes on underground ice at the poles.

* I did the truly pointless and got involved in a thread about theodicy at the Evolution blog at Science Blogs. How does Science Blogs get to pick its members? Do they have to pass some test of anti-religious sentiment before they can join the group?

* The dust cloud in Brisbane of last night (Saturday) was nearly as unpleasant in smell and sinus irritation as the day time one on Wednesday. I can recall no precedent for these at all for Brisbane. Let's hope they do not become a regular spring feature.

* Yay! Free will seems to not have been experimentally disproved after all. Always did have my doubts about the Libet experiments. (Funnily enough, the atheists calling me an idiot at Evolution blog seemed to find the idea of free will, upon which a lot of theodicy is based, a concept also not worthy of belief. Keep them away from moral philosophy, and don't let really serious scientific materialists sit on juries, I say.)

* Finally, especially for Geoff, I thought the middle section of this comment about transhumanists was very funny:

Transhumanists are like the eccentric uncle of the cognitive science community. Not the sort of eccentric uncle who gets drunk at family parties and makes inappropriate comments about your kid sister (that would be drug reps), but the sort that your disapproving parents thinks is a bit peculiar but is full of fascinating stories and interesting ideas.

They occasionally take themselves too seriously and it's the sort of sci-fi philosophy that has few practical implications but it's enormously good fun and is great for making you re-evaluate your assumptions.

Warning issued: blog to be ignored

Now that I have again warned you all about the (possible) end of the world, I have to go for a while and meet with the time travellers from the future who will help prevent this disaster.

The other possible explanation is that I have to stop wasting time on the internet and get serious about raising money at work.

You may choose the explanation that gives you the most satisfaction. I know which I would prefer.

See you soon. (A week should do it.)

Revisiting micro black holes from the LHC

On the potential catastrophic risk from metastable quantum-black holes produced at particle colliders

I have been meaning to link to this for some time, but keep forgetting.

In August, physicist Rainer Plaga put out a revised version of his paper (see above) in which he raised a possible scenario via which the LHC could create a dangerous mini black hole. Basically, it's the original paper with another couple of appendices to it, responding to criticism by the physicists who had done the earlier papers giving reasons why the LHC could not do that.

It is hard for me as a lay person to read papers at this level and understand their maths and arguments. However, again I have the impression that Plaga is arguing in a reasonable fashion, and appears to be making points which are not receiving much attention.

He is apparently no longer working in astrophysics, and his attitude to criticism, and past changes of opinion, have been noted here.

However, the tone of Plaga's paper and response to its criticisms does not sound unreasonable to this lay reader. I just wish there was someone who could go through all three or four papers relevant to the issue, and tell me if my feeling is accurate.

Given the technical problems with getting the LHC running, my concern about this have been somewhat diminished lately. But I would still like to know the answer, as they are likely to get the thing working correctly some time or other.

Scant attention

Gulfnews: More than 80 civilians killed in Yemen air raid, witnesses say

I've noticed for quite a while, via my visits to Gulf News, that there has been a lot of internal turmoil within Yemen. Now we get this alleged incident:
Details have emerged from a government air strike on a refugee camp in the Yemeni province of Amran on Wednesday, leaving more than 80 civilians dead.

Many of the victims were women and children according to witnesses on the ground.

There has been no government comment yet on the strike. Yemen has entered its fifth week of fighting between the government and the Shiite separatist rebels in the northern provinces.
Yet it seems that the Western mainstream media is paying scant attention. Given that it borders Saudi Arabia, I would have thought we should hear more about it.

Chips cashed in

BBC NEWS | Americas | US 'shelves Europe missile plan'

I thought the idea was that the US would pull back on the missile plan in return for Russia changing its tune on Iran.

Instead, apart from getting entertainment from this oddly graphic metaphor:

Russia's ambassador to Nato, Dmitry Rogozin, said the move was "a breakthrough" for US-Russian relations, although they were waiting for official confirmation from the US.

"It's like having a decomposing corpse in your flat - and then the mortician comes and takes it away.

"This means we're getting rid of one of those niggling problems which prevented us from doing the real work," he said.

there doesn't seem to be any trade off from Russia.

We'll have to wait and see, but if the world takes it as a sign of US weakness, I wonder if this may be seen as the start of a re-run of the Carter presidency.

Unhelpful thinking

Lightning kills five Cameroon children - Yahoo!7 News

A lightning bolt killed five children at their school in northwest Cameroon as they were preparing to begin their school day, a local doctor said on Wednesday.

Some 58 others were taken to a hospital near the small village of Bamali, which is some 460 kms northwest of the capital, Yaounde....

Several witnesses, including a prominent traditional ruler, said they believed the event had mystical roots. Belief in witchcraft is common in the West African nation, and a thunderbolt is traditionally seen as a way of settling disputes.

Belief that natural disaster can have a supernatural origin in God is one thing; it may be completely mistaken, but if the belief is in a fundamentally good God, surely the most likely result is self examination as to what sin the person or community has committed so as to deserve punishment.

But belief that accidental death and illness is almost always initiated by your enemy or rival is a different kettle of fish entirely: presumably such thinking is only destined to cause never ending cycles of disputes, fighting, bloodshed or torture in societies where the idea is widespread.

To the extent that Christianity does not have a particularly strong biblical basis for belief in the personal control of supernatural powers for evil purposes, its adoption is presumably an advance in such societies.

Of course, excessive belief in possession, which does have a strong basis in scripture, can be harmful in its own way. I would still think it an improvement for society overall to have some unfortunates mistreated for possession rather than a semi-permanent state of fighting between clans, etc.

Jungian thoughts

Carl Jung and the Holy Grail of the Unconscious - NYTimes.com

I was interested in Carl Jung for a time and read a couple of his books. Certainly, some of his ideas are at least culturally significant, and his conflict with Freud (in which an allegedly paranormal - or at least highly co-incidental - event featured) is pretty important in the history of the ways to think about the mind.

Yet, he didn't exactly lead an exemplary life himself, and some of his self reported dreams (a gigantic God defecating on a church for example) tend to just make the eyes roll.

What's more, he became a popular figure amongst new age nuns and others who want to just talk vague spirituality instead of facing the rigours of morality that traditional religion expects. I expect he was popular for a time amongst those at St Mary's in Exile, although I get the impression liberal Catholics have moved on a bit from him.

Anyhow, this is all preamble to referring readers to the long article in the New York Times Magazine about the release of a journal he kept during his (somewhat early) mid life crisis. Apparently it's full of lurid art and accounts of his hallucinations, and reader's reactions will probably depend on whether they are already an acolyte or not.

An interesting read anyway.
