Back when the United Kingdom was having a referendum on preferential voting, I was very much a supporter. However, I've recently discovered that there are plenty of quite bright people who just don't understand how the system works.

The European Elections will be held four weeks from now, and they also use a system that's more complicated than simply "the person with the most votes wins".

The system used in Britain (and, indeed, most of the EU) is party-list proportional representation using the d'Hondt method. Wikipedia gives a detailed description of the mechanics of the system. However, people without a background in maths might have trouble following it.

So, here's a simpler explanation.

When you vote for a party list, you're giving one vote to the first person on the list, half a vote to the second, a third of a vote to the third, and so on. The people with the most votes win.

For example, let's look at the results of 2009's European Election in Scotland.



I've numbered the top 14 (15th and beyond includes candidates for parties not listed here). Scotland elects 6 MEPs, so the people numbered 1 to 6 were elected.


But what about tactics? That's where things get more complicated.

Proportional representation is supposed to remove the need for tactical voting. However, the way it's done in the UK isn't as proportional as it could be. The country is divided into several constituencies, each of which only elects a few MEPs. The fewer candidates to be elected, the less proportional it is, and the more tactical you can be.

For example, I've received a leaflet from the Greens claiming that they can beat the Liberal Democrats and win Scotland's 6th seat.

You can see in the results above that George Lyon of the Liberal Democrats came 5th, not 6th. You'll also notice that Elaine Morrison of the Greens came 9th, so doesn't appear to be much of a contender for 6th. However, it's not that simple.

While Elaine Morrison came 9th, the candidates that came 7th and 8th did so with fractions of votes. So, while the SNP's Aileen McLeod was only 7,924.17 votes away from 6th place, the SNP would have needed 23,773 more votes for her to actually have won the 6th seat. The Conservatives' Belinda Don was 22,029.5 votes from 6th place, but they'd have needed 44,060 more votes for her to have won the seat. Green Elaine Morrison would have needed 34,485 more votes to win the seat. Therefore, despite being in 9th, she's actually in a better position than the 8th-placed Conservative.

Meanwhile, from the Liberal Democrats' perspective, they would have had to have received just 20,036 fewer votes to have come 7th and missed out on a seat. It's very likely that this will happen this year.

So, the Greens are well-placed to win the 6th seat, but not quite as well-placed as the SNP. However, the Greens stand to gain a lot if they can get out the message that a vote for the Liberal Democrats would be wasted. Which, I imagine, is why they phrased their leaflet the way they did.

I've somehow managed to make it through the whole of 2012 without writing a new post. So, what's been happening?

In March last year I was offered a job at Toshiba Medical Visualisation Systems Europe, so in June I moved back to Edinburgh to work there. This is the third time I've lived in Edinburgh. As they say, the third time's the charm!

I've started learning Swedish for no worthier reason than to better understand Sweden's cultural output. I used to struggle with languages at school, so enjoying learning a language is an entirely new experience for me. It probably helps that, as a native English speaker, Swedish is one of the easiest languages to learn.

I've become involved with EMPS again. See the films section for a recent prize-winning production.

Two of the aspects of Edinburgh I wasn't looking forward to seeing again were the long nights and terrible weather in winter, so after Christmas I took a three-week trip to Australia. This took in the east coast from Sydney to Brisbane, as well as Tasmania and Melbourne. This was also part of my mission to visit every inhabited continent before I'm 30, with only South America left to go. In fact, if you count the Americas as one, my mission is complete!

In October, I moved to Harrow, north west London. This is the first time I've lived near a tube station. Years ago, I would have taken the Underground to see London's most amazing sights. Now, I take it to go to the supermarket. Oh, the glamour!

I've added mini-updates to the main page of the site, so it's a one-stop shop for news, tweets, OpenJazz updates, and sporadic Wikipedia Articles of the Day. It's like a one-man social networking site, assuming you're bad at spotting oxymorons.

In other news, I now have my very own entry on IMDB, thanks to Anne LaBarbera!

So, there's been a lot of turmoil about lately. There's been rioting throughout England. There've also been quite a few people telling whoever will listen what they think of the rioters. Consequently, there've been many rants and counter-rants about who exactly is to blame for the destruction. It goes something like this:

Alice: The looters are bad people, and they must be severely punished.
Bob: The looters are predominantly socially excluded individuals and their actions are a consequence of our society's failings.
Alice: What are you talking about? These people had a choice, and they chose to do bad things.
Bob: How can you possibly think it's that clear-cut?

And so on. It's pretty polarised, and the "Alice" characters are vicious fascists. Right?

I don't think so. I've seen some terribly harsh things written about the rioters by friends who are ordinarily fairly progressive. They've been buying into the idea that the rioters are sub-human and deserve whatever can be inflicted on them, short of corporal or capital punishment.

Meanwhile, I've seen one friend refer to these others as bigots.

Now, before anyone invokes friendship divorce proceedings, take a step back. The riots are still fresh in people's minds. There's been massive, immersive media coverage. We've all been able to see the destruction to people's property and livelihoods, and the general fear and misery that's been inflicted. It's only natural to be angry, and it's only natural to direct that anger towards the rioters. However, anger fades.

Until that happens, I'd advise everyone to be very careful about what they say.

I, however, will opt for mildly inappropriate humour. Look, this guy's looting a lute!

I have now been living in England for a whole year!

I've been taking a look at the site's stats for last year. After OpenJazz, the most popular search phrase was "Doctor Who clipart". Apparently, a non-insignificant portion of this site's visitors end up looking at some low-quality clipart I threw together when I was 13. Sorry, folks.
