One of Your Five A Day?
I therefore found this article "Science and Pseudoscience in Adult Nutrition Research and Practice" by "CSI" (Committee for Sceptical Inquiry) quite interesting.

Points mean prizes
Will review the rejections soon - some I genuinely like far more than others.
I think (though I seem to have lost track!) I have 9 applications outstanding at the moment. I also have two half completed which I need to submit.
How are you all doing on the win/lose/draw front? Many interviews? If so, at the moment, sod off and leave me (and others) to our collective misery!
The worst thing is the people who ask, and are trying to be nice, how the hunt is going. Damn them.
Bitter times.

placebo+nudge=panacea?
I don't think homeopathy works, per se. However, it certainly has an effect when people think it will. Given that many diseases to have a psychological link (look at how quickly many patients recover when told they will be discharged in the next few days) then perhaps it is as well to continue to use homeopathy for 'homely' diseases - ie: fairly regular, uncomfortable but non-life threatening - such as eczema. Just because the science doesn't add up, if the sugar pill has the same affect on the patient as the 'real' pill and sugar is cheaper, give out lots of sugar pills.
The time I think there is a problem is obviously for diseases such as cancer. If people have got used to believing the sugar pill works for their coughs and colds, I can easily see a number of people trying the same for their cancer.
In the economy, I agree with the article's 'unethical' point, but equally, all of the economy is a confidence game (I don't say this is bad) so perhaps there could be a middle line to tred betweenthe outright lie and the modifying of behaviour - perrhaps a 'nudge' is what is needed.

Japan and languages
Decided that seeing as the Japanese are allegedly about as good at foreign languages as the English it would be a good idea to spend the next few months being able to read and speak some Japanese before I go.
Turns out, after a very brief bit of internet research, that having learned Chinese for a year is helpful when it comes to one of the three scripts that they use. More helpfully, Salford University offers evening classes which I think I might take up as they seem reasonably priced and I can (just) get from the office to the classroom by 6.
I have to say, I've missed learning stuff since leaving uni. The job has been quite good in that repsect as most of it is still new, but I like to learn for it's own sake and I think languages could be useful in this regard.
I'm too old to become fluent in another language - though I am encouraging the Boy to get work in Germany if he can because that would be my best bet for a second fluent language - but I think it would be good to have c250-1000 words in say 15-20 languages and a smattering of grammar. Means you can be understood literally anywhere in the world and could usually get around.
So far on that list I probably only have 4 - good German, basic French, very basic Chinese and very very basic Turkish. By very, very basic I mean I can count to ten, ask where stuff is, order various foods and drinks and haggle at a market as well as the various 'polite words' - it's all vocab, no grammar.
In non-Roman scripts, learning how to look a word up in a dictionary can take ages in its own right. Try "我是英国人" without using an online dictionary. And typing into a computer is also a lesson in itself (in this case, I typed the pinyin in making sure it was on Chinese input setting and the computer converted the pinyin into characters)

The human side of the second law of thermodynamics
By worse environments, I don't mean surrounded by bad people or violence or crime.
Litter, disorder (mislaid shopping trolleys) and graffiti all made people behave in less acceptable ways than when the same situation was set up in a tidy/pleasant area.
Well worth a read, here.

How babies are made: the 6 year old view
5 Children were asked how they thought babies were made.
To be fair to them, they are quite accurate on the whole and even where wrong, it's the result of a wrong logical leap rather than anything their parents seem to have told them.
Admittedly, though, most of them ge a little lost after 'an egg hatches in Mummy's tummy' analysis....

Teaching evolution in schools
I especially like the conversation he has with a student about the purpose - and limits - of science:
Teacher (Mr Campbell):“Can anybody think of a question science can’t answer?”
A student: “Is there a God?”
“Good,” said Mr. Campbell, an Anglican who attends church most Sundays. “Can’t test it. Can’t prove it, can’t disprove it. It’s not a question for science.”
Bryce (a student who reads the Bible as literally true) raised his hand.
“But there is scientific proof that there is a God,” he said. “Over in Turkey there’s a piece of wood from Noah’s ark that came out of a glacier.”
Mr. Campbell chose his words carefully.
“If I could prove, tomorrow, that that chunk of wood is not from the ark, is not even 500 years old and not even from the right kind of tree — would that damage your religious faith at all?”
Bryce thought for a moment.
“No,” he said.
The room was unusually quiet.
“Faith is not based on science,” Mr. Campbell said. “And science is not based on faith. I don’t expect you to ‘believe’ the scientific explanation of evolution that we’re going to talk about over the next few weeks.”

Firefox 3.0
Love the new zoom function. Ironically, was looking for it yesterday on the old version and couldn't find it - think Mozilla corp. is reading my mind!
Not yet so sure about the 'guess what you mean' address bar. I can see how it would be useful if you can't remember the name of a site, but if I type in "thi" it used to take me to the main page of this blog. Now it makes a million suggestions and I have to scroll. Firefox say that it does learn your preferences over time, so maybe this'll fix soon. If it learns quickly, I can definitely see how it would be useful.

UPDATE: actually, it's already learned. This time when I typed it, the main page was the first option. Clever browser :-)

Risks and Liberty
I agree with him that perhaps 'risk' should be taught in schools. Perhaps it could replace general studies?

What makes us human?
In her view, it's our ability to experience empathy and worry about the wider picture rather than just worry about ourselves and where our next meal is coming from. More here.

Pineapples/Ananas

The fruit hit Europe in the 16th century and the original South American word for it was "Anas", the additional "An" at the beginning being a grammatical notation.
Why is English the only language that doesn't call it ananas? I mean, pineapple makes logical sense - tastes like apple, looks like a pine - but why are we the only ones who decided to change it?
I'd be interested to know what it's called in Basque, Finnish and Roumanian as I believe that those three languages are some of the most unique in Europe and don't share their root with the Indo-European language upon which most other languages in the region are based.

Abortion
It's difficult, I think abortion is horrid, wicked and wrong. It should be quite right to try and reduce the number of abortions and abortion should not be applauded.
Yet I'm pretty sure that if I was to find myself pregnant tomorrow, I'd have one. Even if my life is stable enough today that I'd continue with the pregnancy, I know that if I'd have found myself pregnant a couple of years ago, I certainly would have had one.
Of course, I'm in the slightly nicer moral zone of having taken the type of precautions in advance that I hope mean I will never have to make the choice.
If a woman has become pregnant whilst using contraception, or after she though she could no longer bear a child or - obviously - in the especially nasty situations of rape etc, then I have no condemnation for that women. The pregnancy is not her fault, either because it was not foreseeable that it should happen because she was taking steps to prevent it or because not being able to take the relevant steps was forced on her by another.
However, regardless of the circumstances in which a woman became pregnant, I feel that a line must be drawn somewhere. The question therefore becomes, where should that line be drawn? In the UK at the moment, it's 24 weeks. In other European countries, it is much lower - I believe the limit in the Netherlands is 16 weeks.
Whatever the teachings of the relevant authorities say on the subject, I simple cannot believe that a fertilised egg is 'alive'. If the potential for life is the criteria, then with modern technology, we could make a human from the DNA in my hair. We can grow back fingers that have been chopped off (it looks like magic!). The potential for life is everywhere.
Equally, I cannot accept that a 39 week old foetus is not alive. If it were born, even without intervention, it could survive. It feels pain, it moves, it responds to external stimulus, it just feels human as a gut instinct.
Many people point out the irony of there being two wards in a hospital. In ward A, the doctors are aborting a 22 week old foetus. In the other, they are saving a pre-maturely born 22 week old child.
The idea of basing abortion time limits on the viability of a child (with medical assistance) is superficially attractive and feels fair. However, whilst it seems to be an appropriate moral ground upon which to base the decision at the moment, in the long run I think it is dangerous. 16-24 weeks shows a balance of interests between the mother and the foetus. But, medical technology is always improving and maybe, in the future, there will be viability at 6 weeks, or earlier.
Then there is no balance.
I think we need to find a different moral basis on which to base the decision.
More posts when I think of what it might be.

Net Neutrality
The first problem with net neutrality is that it doesn't mean just one thing specifically. It's broad meaning is that on the internet, traffic shouldn't be prioritised in anyway. An example would be when you make a phone call, you expect it to connect regardless of who you're phoning and on what network. On the rare exceptions that it doesn't connect, it's either because the line is busy (new year, for example) or because, for exceptional reasons, other calls have been given priority (for example, the 7/7 bombings in London meant emergency calls got priority). So net neutrality isn't an absolute, but it is a good general rule to be broken only in exceptional circumstances.
Broadly speaking, there seem to be three principle meanings of net neutrality:
(1) absolute net neutrality: Everyone gets equal access, all data is treated equally. When the internet is busy, it slows down for everyone.
(2) limited discretion without quality of service tiering: similar to the above, but occasionally someone gets priority. This is not on a 'paid for' basis however, everyone has fundamentally rhe same access
(3) limited discretion and tiering: If you pay more for your connection charge, your internet traffic gets priority over the person who paid less. Companies such as Eclipse operate this system in the UK already.
So why is this an issue now?
Well, it's been coming up for a while as the internet offers more and more programmes which need large amounts of data to work. Even sites such as nationalrail or multimap use more bandwidth now than they did 12 months ago, and they perform reasonable simple operations. You've probably noticed how slowly many Facebook pages open now because their owner has so many applications on them. Broadband means people are less likely to stickat just downloading a single song or a single tv programme, they want the who album or series. Their download moves from 5mb and 350mb a time to 100mb and 6gb respectively. However, ISPs have largely been able to cope with the traffic caused by this, especially for downloads.
A year ago, if you were using 20gb a month, the ISP knew you weren't just reading text pages or going on youtube occasionally, it was fairly clear you were downloading films etc. You knew you were doing wrong, the ISP knew you were doing wrong and so even though you'd signed up for 'unlimited' internet, in reality, the 'fair usage policy' was an effective threat.
About a year ago, the BBC introduced its i-player. About 6 months ago, it began to allow people to stream programmes rather than downloading them. The number of people taking up the offer to watch TV programmes legally was huge. ISPs in the UK are complaining that they can't handle the additional bandwidth needed for this. Most people are pointing out that the service was sold as 'unlimited' and the ISPs should provide.
No doubt internet traffic is going to grow and grow. The amount of space available, one assumes, cannot expand indefinitely. At some point, therefore, access is going to have to be restricted.
In my mind, there are three models for this:
(1) The way internet is commonly advertised in the UK is as '2 mb download limit', '20 mb download limit' and 'unlimited' (or similar). The price of the 'unlimited' packages would have to increase fairly substantially to reduce internet usage and the lower download limit packages should explain exactly what a person gets for 2 mb. So, solution 1 is just an expansion of the currant system
(2) people explicitly pay for priority (like the eclipse link mentioned earlier). If you are on the £10 package, you get the lowest priority. In the evening, your internet slows to snail speed and so you set up most of your downloads to take place at night when it's faster. If you pay a bit more, you're less affected by busy periods. If you pay the most, your internet is always the fastest possible.
(3)The 'everyone suffers' model: most people still sign up for 'unlimited' broadband because it's still cheap, no one is explicitly prioritise and so when the net is busy, all suffer equally.
I'm not wholly sure what is the most desirable. I've been on the lowest tariff of model 2 and in the evenings by internet was slower than dial up. I had to use the 'text only' versions of most pages. I wasn't able to change my option easily (it meant typing into a new 12 month contract). If people could change their option instantly, say, a 1 month long contract, I could support option 2 a lot more.
Option 1's weakness is people's ignorance. People genuinely don't understand how much 2mb of data is. and even if it's explained to them, will forget until they are charged for the extra usage. Whilst I'm usually a fan of the 'stupid people can't be helped' variety of policy, I can't help but feel when something is reasonably complicated we should probably cut them a little more slack.
Option 3 is what will happen if nothing happens and the amount of internet space can't expand. It's basically the NHS version of the internet, but without the option of going private.
My hope is that technology will keep up or have a new breakthrough. With computers and the internet still be very new technology on the grand scale of things, I hope someone clever in a lab somewhere comes up with an idea so net neutrality can be maintained without anyone having to suffer.
There is one other, less contraversial, issue on this topic. Some ISPs want to try and prevent their customers from connecting to (legal) material on the internet. I don't think anyone woul;d object to laws preventing connection to what is clearly illegal material (child porn, for example), where material is doubtful, the customer should be allowed to download and just be prosecuted later (torrent hosting sites usually contain copyrighted material, but there can be a legal use for torrents too). But where there is no doubt over the legality, and it is only because the ISP has a competitive interest in restricting access (for example, if google.com were an ISP, it may want to restrict access to yahoo.com, its rival) then I would argue that ISPs should not, generally, be allowed to do so. If they wanted to offer a lower priced, restrictive package but where the customer was explicitly told which sites were blocked, I would have no problem. But I don't trust them to be clear and explicit when they advertised or sold the restrictive passage.
I think my main support from net neutrality comes from the angle that although I broadly support the concept of caveat emptor, when it comes to internet provision, many people don't even have the basic knowledge they need to understand the marginally more complicated aspects of buying it. Giving people this knowledge is reasonable difficult and the ISPs can't be trusted to provide it in a manner which the majority can understand. In this case, therefore, I can (at least temporarily) see the point of legislating to maintain net neutrality.
