Carly’s Law

by Stubborn Mule on 1 February 2010

Fifteen-year-old South Australian Carly Ryan was murdered in 2007. The 50-year-old man found guilty of her murder had used fabricated online identities to attempt to seduce the girl and, when she ultimately rejected his advances, he used another identity to lure her to a beach-side town where he bashed and drowned her.

Independent South Australian senator Nick Xenophon now intends to introduce a private member’s bill which would make it an offence for an adult to misrepresent their age online for the purpose of meeting minors. Carly’s mother, who plans to establish a foundation to promote awareness of the risks children face online, has said she supports the bill.

The story of Carly Ryan is terrible. Just hearing the story triggers a shiver of disgust and horror and those who are parents themselves may well be worrying about the risks posed to their own children by shadowy online stalkers. Politicians are human too and react the same way. Indeed Nick Xenophon’s reaction follows a common pattern that has emerged around the world in recent decades.

The pattern starts with a terrible crime committed against a child. This is followed by extensive and sometimes lurid media coverage. A politician will then call for new laws to “prevent this happening to others”. It would be a brave politician who would argue against such a law and thereby risk appearing insensitive to the plight of the victim and the grief of their distraught family. So they do not oppose it and new laws are passed. The pattern is clearest in the United States. The archetypal example is Megan’s Law. In 1994 seven-year-old Megan Kanka was raped and murdered by a repeat sexual offender. Her name has since been attached to laws introduced across the country requiring a public register of sex offenders. Other examples fitting the pattern include Jessica’s Law in Florida which imposes a minimum 25-year sentence on sex offenders. Nick Xenophon’s “Carly’s Law” could well be another in this sequence.

But, how effective are laws like this in curbing the criminal behaviour they are targeting? [click to continue…]

Rethinking the basis for the Australia Day holiday

by John Carmody on 25 January 2010

In anticipation of tomorrow’s Australia Day holiday here in Australia, this guest post by John Carmody examines whether or not 26 January is really the most appropriate date for Australia Day. John Carmody is a Sydney-based writer on medical and cultural history and (in the interests of full disclosure) is closely related to the Stubborn Mule.

January 26 is a nettlesome date for the official celebration of the Australian nation and as a commemoration of our colonial foundation.  Apart from the significant nuisance that it falls so close to the end of the holiday season when our minds and emotions are trying to deal with more pressing obligations, it really asks a serious philosophical and moral question.

For indigenous Australians, conscious of their fraught history since 1788, it is no cause for celebration at all.  Understandably, they consider that it was the beginning of an invasion and see no reason to rejoice in it.  White Australians and, indeed, all immigrants can only respect that attitude; but we must do that reflectively.  The fact is that there are several distinct reasons to discard 26 January as that festive occasion.

The first point is that the date is not when the founding fleet arrived in Terra Australis: that was, rather, at Botany Bay on 19-20 January, 1788.  It was only because the officers were so disillusioned by how little resemblance that coast bore to Joseph Banks’s glowing descriptions and because of an indifferent water supply, that Governor Arthur Phillip made a reconnaissance to Port Jackson (which Captain Cook had not entered) that the venture was transferred to Sydney Cove. Even then, in the afternoon of 26 January there was little time for formalities or any grander celebration than hoisting a flag and drinking the health of the King and the success of the colony with a few glasses of Porter, followed by the flourish provided by a round of rifle fire.

Left, Right and Climate Change

7 January 2010

In the wake of the singularly unproductive COP15 Climate Change conference in Copenhagen, I have been reflecting on the polarisation of views on climate change along political lines. Whether or not human activity is leading to climate change is a question of scientific fact: it is either happening or it is not. So knowing someone’s [...]

Banks, Central Banks and Money

18 December 2009

One misconception about the mechanics of money that I mentioned in my last post is the idea that banks can hoard their reserves at the central bank* rather than lending them out.
Here I will explain why this idea simply does not make sense, but no more casinos and gaming chips. No more senior croupiers and [...]

How Money Works

11 December 2009

Over the last couple of years as the global financial crisis unfolded, a subject I have spent a lot of time thinking about is the nature of money. I have been planning a blog post on the topic and the time has finally come.
The catalyst for finally writing this post was attending last week’s 16th [...]

Which countries work the hardest?

1 December 2009

Last week over dinner with friends, a debate arose as to whether Australians worked harder than Americans or not. Since we had more wine than data, the argument did not last very long and we instead moved on to the question of whether China now more closely resembles a fascist regime than a communist one. Reflecting later on the first discussion, I decided to dig up some data on hours worked and attempt to determine a winner for the debate.

Deceptive Charts #2

20 November 2009

Last month I wrote about the dangers of secondary axes, but even charts with a single axis can be deceiving. I have been reflecting on this after reading Jon Peltier’s critique of Microsoft’s “professional” charting tutorials earlier this week. One of the charts Peltier takes issue with is a column chart which has the value [...]

Mahalo 3.0: my new mechanical Turk

19 November 2009

Almost a year ago I posted about using twitter as my very own mechanial Turk. Here’s part of what I wrote back then:
The original mechanical Turk was an 18th century machine that purported to be able to play chess. It was, however, a hoax as a human hidden inside the machine was actually doing the [...]

Hot and Dry Days Ahead for Australia

13 November 2009

Earlier this month, the Australian Bureau of Meteorology released the October figure for the Southern Oscillation Index (SOI). It showed a precipitous plunge of almost 20 points down to -14.6. Just how significant a drop this is can be seen in the chart below, which shows the distribution of monthly changes in the SOI going [...]

Melbourne Cup by Numbers

2 November 2009

I don’t know anything about horses. Ever since I was bitten by one at the Easter Show as a small child, they have ranked very low on my animal preference list: only just above geese. Still, at this time of year almost everyone in Australia gets caught up in some way with the Melbourne Cup, [...]
