Worthwhile Canadian initiative


There is an economics blog called "Worthwhile Canadian Initiative," supposedly named after a phrase that won a contest for "most boring possible headline."  Today I ran across a real-life WCI, an amazing example of the strengths of the  public health approach to problems so characteristic of my adopted country (as opposed to the moralistic approach elsewhere, but unfortunately now being imitated by the current federal government).

This WCI is likely going to be buried, but I am going to do my bit to spread the news, which I read in the Ottawa Citizen:
The number of rabies cases in Ontario's foxes, skunks, raccoons and livestock has just doubled. But paradoxically, this doubling is a minor blip.
Through most of 2011 there had been only a single rabies case in the entire province. As of last week, there are two. One new case was enough to double the total.
Two rabid animals, in the province that was once the rabies capital of North America, with thousands of confirmed cases a year.
One of the most stunning victories in the fight against infectious disease has been fought and won in Ontario, which had more than 3,000 cases of "terrestrial" rabies (meaning all animals except bats) in 1980.
Back then, Ontario had more rabies than all other provinces and U.S. states combined. The disease threatened children, hunters, livestock, and household pets.
For reasons never really understood, today's commonest strain of rabies crept south from Arctic foxes in the 1950s, spreading in animals' saliva along Hudson Bay to Ontario, where it stayed - not just in foxes, but commonly in skunks and raccoons too.
It's almost all gone now. And a strain called raccoon rabies, which spread north from Florida, has been completely wiped out in Ontario since 2005.
The strange story of how we rid the province of nearly all rabies is a combination of vaccine research, animal psychology, and the skill of bush pilots.
...
Here's what happened. Around 1980, someone had the bright idea of vaccinating wildlife against rabies. After all, it works in dogs and cats.
Obviously the problem was delivering the drug in the wild.
The solution was blindingly simple: Put oral vaccine in meatballs. A government airplane flies low with a pilot, navigator and bombardier, and they drop vaccine-laced bait onto the land below.
The bait also contains tetracycline, a common antibiotic that stains an animal's teeth brown. That reveals what proportion of wild animals are taking the bait.

There's more.

The situation of Arab Christians


Daniel Philpott:
A tense subplot of the Arab Spring is the increasing endangerment of the region’s Christians. In Egypt, Coptic Christians, 10% of the population, have been attacked repeatedly by Salafist Muslims unleashed – many literally released from prison -- by the fall of President Hosni Mubarak. No wonder that Christians in Syria now fear their fate at the hands of the country’s Sunni Muslim majority should President Bashar al-Assad’s government fall.
The experience of Christians in Iraq is hardly encouraging, either. The kidnapping and murder of Chaldean Catholic Archbishop Paulos Faraj Rahho by Muslim militants in early 2008 is emblematic of what Iraq’s Christian community has suffered since the fall of Saddam Hussein. The population of Iraqi Christians has declined from around two million to around 400,000 since the Gulf War of 1991, which weakened Hussein’s rule. Under the dictatorships of Mubarak, Assad, and even Hussein and Qaddafi, all of them unsavory to be sure, Christians enjoyed relative security, though it was sometimes bloodily interrupted and usually attended by pervasive social discrimination. Arab authoritarianism was a leaky shelter but it was nevertheless a roof over their heads.

But however dangerous Arab Christians’ fate now may be, going back to the good old days of dictatorships is not an option. The surge of democracy-demanding youth, popular impatience with corruption and economic stagnation, and a religious reawakening over the past generation all serve to block such a backslide. Of course, for other minorities and for Muslims at odds with their regimes, the good old days were not good at all. They were not good for the residents of Hama, Syria, 10,000 of whose inhabitants were murdered by the current president’s father, Hafez al-Assad; and they are not good for protesters of the son’s dictatorship, over 2900 of whom the regime has killed by now. They were not good for democracy activists or traditional Muslims in Egypt, over 20,000 of whom Mubarak held in his jails. Arab authoritarianism was a model that could not last. Apart from suppressing the dynamism of democracy and the free market, such regimes were repressively secular, creating legions of religious discontents and radicalizing traditional Muslims, often in the direction of violence. Ultimately this shelter for Christians proved to be not only leaky but rotten at its foundations.

The position of today’s Arab Christians is indeed precarious. Among the possible outcomes, Islamist regimes that afford Christians little freedom to practice their faith or participate in politics are entirely plausible. But this outcome is far from inevitable, no more inevitable than was the persistence of dictatorship. Only this past week, elections in Tunisia, the country that ignited the Arab Spring, gave a plurality of votes to an Islamic party, but one that is relatively liberal and that will rule in coalition with non-religious liberal parties. In Egypt, too, the possibilities are more complex than secularist safety and Salafist violence. When Christians are attacked it is not always at the hands of Muslims. The shooting of Christian demonstrators in Cairo this past October 9th was carried out by the army. When Muslims have attacked Christians, far more have defended them. Just after Muslim terrorists slaughtered 25 Coptic worshippers and injured some 100 others in Alexandria on New Year’s Day of this year, thousands of Muslims across the country gathered in candlelight vigils and formed human chains around Coptic churches during worship. Today, Egyptian Muslim office-seekers are divided among proponents of a strongly Islamic state and supporters of liberal rights, including religious freedom for Christians. The scenario of religious freedom, then, is plausible, too.
He goes on to discuss what outsiders might do to help.

Economics as pseudo-science


The Globe and Mail has a substantial article on how the pretentions of economists to be scientists and practitioners of a purely math-based discipline have helped bring us to the current disaster.

A former colleague at my university warned me  about this 20 years ago.  He said the leading economics department he had trained in was abandoning economic history entirely.  Indeed it was abandoning economics. When they recruited grad students, they ignored graduates from their own bachelor program in favor of the best math graduates they could get.  Such was their faith in abstract mathematics.

Ancient brews recreated

Mcleans reports:

And then there’s Patrick McGovern, an archaeologist at the University of Pennsylvania who, after analyzing the residue that lingers in the nooks and crannies of millennia-old potted vessels, is bringing ancient elixirs back to life. It’s gastronomical nostalgia on steroids.

McGovern, a pioneer in the field of biomolecular archaeology who did undergraduate work in chemistry and has a Ph.D. in Near Eastern archaeology, has collaborated on five beverages with Sam Calagione, the award-winning founder and president of Dogfish Head brewery in Delaware: Midas Touch, an Iron Age beer based on samples found in the king’s supposed tomb; Chateau Jiahu, a Chinese blend of grapes, rice and honey based on the oldest sample of booze ever discovered; Theobrama, a 3,200 year-old Honduran chocolate drink; Chicha, a corn beer with Peruvian lineage; and Ta Henket, an Egyptian ale being released in December with 18,000-year-old components.

Polite Canadians

The Globe and Mail reports on what happens when you give 'em a gun and the prospect of filling the freezer with moose meat.

Armed gangs defending their turf. Death threats and torched property. Victims too fearful to go to police.

Sounds like another organized-crime offensive on the streets of Montreal. But the action is playing out in a more improbable setting: the backwoods wilderness of Quebec during hunting season.

Generations of hunters have turned to the rugged forest of the Gaspé Peninsula each fall to bag a moose, but an explosive growth in the number of animals, coupled with growing competition for hunting spots, has turned nature’s idyll into a battleground.

Although Quebec sets aside vast swaths of Crown land for hunting, territory that in theory belongs to everybody, some take matters into their own hands to protect what they regard as their personal hunting spots.

The problem has come to a head on the Gaspé, where some 25,000 permit-holders descend in the forest in a nine-day firearm hunt lasting to late October. During that time, according to several officials and witnesses, a supposedly public playground gives way to roadblocks, armed patrols and less-than-subtle warnings by rival hunting gangs to keep out.

Some hunters are tasting the woods’ frontier justice firsthand. Michel Guénette is a 54-year-old truck driver who has been hunting in the Gaspé since he was a boy. Last year he discovered his family’s six trailers incinerated, with empty canisters of propane lying amid the rubble. When he showed up for the hunt this year, his tree blind was trashed.
There's more where that came from.

Astonishingly good

Law and Order SVU is in its 13th season and I have to say, that although  in the normal course of events the series should be as stale as thirteen-year-old bread, in some ways it is better than ever.

The most recent episode was classic SVU.  It could easily have been in season one -- heck, it would have been a good pilot, introducing the whole series.  But somehow it pulled me in, really pulled me in.  Was it the acting?  The direction?  Who knows? 

But what  really started this train of thought was the previous episode, about a young loser couple whose infant dies mysteriously.  It was heartbreaking, and though the case was only marginally an SUV matter, it  may have been the best episode ever.  Here I have to say that the people who played the young couple were astonishingly good, and the writers should be proud.
