A riveting piece by Elizabeth Green in Sunday’s Times magazine on the coming revolution in teacher preparation. Rarely for a Sunday magazine piece it is well worth reading the whole thing. She takes as her starting point the movements for deselection (firing teachers — my rule of thumb is that the more someone talks about firing teachers the less likely it is that they will actually do it) and merit pay, and points out:

So far, both merit-pay efforts and programs that recruit a more-elite teaching corps, like Teach for America, have thin records of reliably improving student learning. Even if competition could coax better performance, would it be enough? Consider a bar graph presented at a recent talk on teaching, displaying the number of Americans in different professions. The shortest bar, all the way on the right, represented architects: 180,000. Farther over, slightly higher, came psychologists (185,000) and then lawyers (952,000), followed by engineers (1.3 million) and waiters (1.8 million). On the left side of the graph, the top three: janitors, maids and household cleaners (3.3 million); secretaries (3.6 million); and, finally, teachers (3.7 million). Moreover, a coming swell of baby-boomer retirements is expected to force school systems to hire up to a million new teachers between now and 2014. Expanding the pool of potential teachers is clearly important, but in a profession as large as teaching, can financial incentives alone make an impact?

There is no alternative but to prepare teachers better for the task.

This is a travel bleg. In a couple of weeks’ time, I hope to meet up with my beloved who’ll briefly be in Fort Benning, Georgia, and spend a weekend travelling together in Georgia or Alabama. His initial thoughts lead to south Georgia and the coastline or perhaps into Alabama. Mine are more a night in Athens, soaking in some music, and a drive around the classic heartland. The cherry blossoms in Macon also appeal, though we’ve got plenty of those in D.C. We’ve already been to Savannah and are more interested in visiting smaller towns this time, and getting a feel for another side of America. 48 hours is a very short time so spend in a place I’ve wanted to visit for so long. We’ll be flying back from Atlanta but don’t plan to spend time there. Any wisdom to offer?

The deadline for the manuscript of Zombie Economics (last complete draft here) is only a few weeks away, and the zombies are popping up faster than I can knock them down. I’m adding a section on reanimated zombies to each chapter. Over the fold is the social mobility defense of trickle down economics, as animated by Thomas Sowell. There’s still time for me to benefit from your comments.

And today (still today as I write in the Midwest; I realize it is over in the UK) is the 25th anniversary of the end of the Miner’s Strike. The Radio Ballad is quite moving (although, no doubt, designed to provoke cries of BBC bias). Chris marked the 20th anniversary of it’s start here.

A week or so before the end there was a large demonstration in London.

BBC obit here (with weird comment from Gordon Brown — “unifying leader” — what party was he in during the 1980s I wonder?). FWIW my own thoughts about Foot are here.

I discussed the ‘no statistically significant warming since 1995’ talking point on my blog recently This talking point has been around the delusionist blogosphere for some time, though with a lower profile than ‘global warming stopped in 1998’, and was put as question to Phil Jones of UEA in a BBC interview. Jones answered honestly, if a bit clumsily, that the data period since 1995 is marginally too short to derive a statistically significant trend, a response which was headlined by the Daily Mail as “Climategate U-turn as scientist at centre of row admits: There has been no global warming since 1995?” and became the talking point of the day. As has been widely noted, confusing not statistically significant’ with ‘not significant; in the ordinary sense indicates either deliberate dishonesty or ignorance of a point covered in excruciating detail in every introductory stats course.

But where did this silliness come from? I’d seen Janet Albrechtsen quote Lord Monckton on the point, and it seemed about right for him, an innumerate debating point that would take a fair while to refute, during which time he could move on to the next one.

Imagine my surprise, then, when I discovered the point being made (and apparently originated) by Richard Lindzen of MIT who is (or ought to be) by far the most credible figure on the delusionist side. In a piece published on “Watts Up With That” Lindzen says ‘There has been no warming since 1997 and no statistically significant warming since 1995’. Lindzen illustrates this claim with a graph he appears to have made up for the occasion, complete with unexplained error bars (I’ve appended a NASA graph with error bars for annual estimates).

In this piece for Quadrant he gives a variation, saying “has been no statistically significant net global warming for the last fourteen years” and “the fact that warming has ceased for the past fourteen years is acknowledged” . Note the slide from “has been no statistically significant net global warming for the last fourteen years ” to “warming has ceased”, committing the basic newbie error against which all budding stats students are warned.

Lindzen has published a couple of hundred papers in climatology, so I think we can assume he knows that the statement “there has been no statistically significant warming since 1995” means nothing more than “given the variability in the data, we need at least 15 observations to reject the null hypothesis at 95 per cent confidence”, a fact so trite as not to be worth mentioning.

It is sad to see a respected scientist reduced to this kind of thing. And as far as I can tell, all this is simply to avoid admitting that he backed the wrong horse back in 1990, when he bet that he was smarter than the majority of climate scientists who thought humans were (probably) causing global warming. The data since then has supported the majority view, but instead of revising his position, Lindzen has resorted to dishonest statistical trickery.

To quote The Economist, with respect to the Daily Mail

Since I’ve advocated a more explicit use of the word “lie”, I’ll go ahead and follow my own advice: that Daily Mail headline is a lie.

But at least the Daily Mail headline writer could plead ignorance. Lindzen has no such excuse.

From the New York Times:

bq. The alliance of Interior Minister Jawad al-Bolani held the largest rally in Baghdad to date, with hundreds filling a large outdoor soccer stadium on Saturday. But it was not exactly a show of overwhelming public support. Many in the crowd were police officers employed by Mr. Bolani’s ministry. One officer, speaking on the condition of anonymity, said his battalion had been ordered to attend. The event was as notable for security as it was for political theater. Iraq Army helicopters circled low overhead, American Apaches higher in the sky. Streets were closed in all directions, snipers lined rooftops and each candidate had his own security detail, forming a phalanx around Mr. Bolani’s tent, a sea of machine guns and stony stairs. At the end of the rally, doves were released as a symbol of peace. Unfortunately, they were set free just as fireworks burst in the sky, catching many birds in the cross-fire.

Brad DeLong:

DragonDictate for iPhone had better learn not to write “Martian” when I say “Marshallian”. Just saying.

It’s not often you see a case where the jokes literally write themselves.

The Washington Post “runs an editorial”:http://www.washingtonpost.com/wp-dyn/content/article/2010/02/28/AR2010022803429.html on the topic of the financial data privacy controversy that I “blogged”:https://crookedtimber.org/2010/02/16/in-praise-of-the-european-parliament/ about a couple of weeks ago. Predictably, it’s an ill-informed harrumph.

bq. THE PROGRAM has been credited with helping to capture the mastermind of the 2002 Bali nightclub bombings that killed more than 200 people, including some 50 Europeans. … Yet almost 400 members of the European Parliament want nothing to do with it and have effectively and indefensibly shut it down. … The tool in question is the Terrorist Finance Tracking Program, which the United States created shortly after the 2001 terrorist attacks in hopes of using financial transactions to trace the whereabouts of suspects. … The European Commission hashed out an interim deal to allow the United States to continue operations, but the European Parliament objected, largely on the basis of bogus privacy concerns. … The Obama administration should work with E.U. leaders to push for reconsideration. If need be, additional oversight should be considered. But the administration must not go too far. Gutting a legal and effective program for the sake of imagined privacy gains would be as unwise and potentially dangerous as having no program at all.

I know that when the _WP_ editorial team sees the words ‘tracking terrorism,’ it responds with precisely that degree of judicious consideration which you apply when the doctor whacks your funny bone with a pointy rubber hammer. But the noxious guff about “bogus privacy concerns” and “imagined privacy gains” is just that – noxious guff. The program that the Washington Post is so fond of was implemented in blatant violation of EU law for years before the NYT had the guts to reveal its existence (despite strong pressure from the Bush administration not to do so). Nor are the European Parliament’s privacy concerns ‘bogus.’ The current administration has consistently refused to provide any guarantees whatsoever about how this data might, or might not, be shared with third countries. Given that many of our soi-disant allies in the war on terror have a distinctly robust attitude to the treatment and detention of possible terrorists, Europeans may very reasonably worry that any data they provide will be used to imprison and torture people, some innocent. I’ve talked about these issues with MEPs a lot over the last several years. Their memories of extraordinary rendition and the use of shared information (between the US and Canada in this instance) in the “Maher Arar case”:http://en.wikipedia.org/wiki/Maher_Arar left a very bad taste in their mouth. Nor is the US willing to talk about real redress or compensation for people unjustly targeted via this data.

In any event, like it or not, the editorial writers of the _Washington Post_ are going to have to learn to live with a transatlantic relationship where an actor which cares about privacy can veto security arrangements. Abe Newman and I recently wrote a “piece”:http://www.foreignpolicy.com/articles/2010/02/26/europes_parliament_takes_a_stand?page=full on Foreign Policy‘s website that talks to this.

bq. To build support for counterterrorism cooperation, the United States must explicitly accept that the European Parliament will play a key role in future negotiations. … The U.S. administration must treat the Parliament as a true negotiating partner, along with the EU member states, on information sharing and domestic security. The U.S. administration can also address the Parliament’s substantive worries by creating its own privacy oversight structures and extending its protection to European citizens…. If the United States wants to rebuild the transatlantic relationship and promote its own security interests, it must stop treating the European Parliament as an irrelevant afterthought.

Cambridge has just published a new book, Measuring Justice: Primary Goods and Capabilities (UK), which Ingrid and I edited (the idea of doing it was entirely Ingrid’s, I should say, and a brilliant idea it turned out to be). Its a fairly tightly focused collection, for which we invited two kinds of contribution. It opens with a shortened version of Pogge’s essay “Can the Capabilities Approach be Justified?” which many of the contributors refer back to, and the first part continues with a series of chapters considering the relative merits of Rawls’s social primary goods approach and the capabilities approach to the metric of justice; for this we invited contributors whom we believed would defend one or another of these metrics while giving careful criticisms of the rival, plus Dick Arneson whom we believed (rightly) could be relied on to help make progress despite not being associated with either view. For the second part we invited contributors who would think about some specific issue of justice (in health, education, gender, the family, disability) and consider the relative merits of the approaches with respect to that specific issue. We wrote a short analytical introduction which locates the debate in a broader context, and which, we hope, helps guide the reader through the book (the CUP page has a pdf of it, so you can judge for yourselves); the book concludes with a nice, partly autobiographical, essay by Sen engaging with the chapters in the first part of the book. The contributors so far unmentioned are Erin Kelly, Elizabeth Anderson, Norman Daniel, Lorella Terzi, Colin MacLeod, and Elaine Unterhalter. This is the second volume I’ve co-edited for Cambridge, and both times they have come up with much better titles than the editors would have done, good-looking but demure covers, and, most importantly, a reasonable price.

Discussion on my last post on reanimated zombie ideas in economics touched on a lot of the themes I want to talk about in this one, about the efficient markets hypothesis and why this undead monster can never be laid to rest. (Warning: favorable references to Popper ahead!).

I’m adding a little section to each of the chapters in my Zombie Economics book called “Reanimation”, about the attempts that are already under way to revive economic ideas killed (at least according to the standard rules of hypothesis refutation) by the global crisis. I wasn’t surprised to find plenty of examples for the efficient markets hypothesis (easy to render immune from any kind of refutation by an appropriate formulation) or for policy ideas that yield big benefits to the rich and powerful, such as privatisation and trickle-down economics. But I was surprised a little while ago to see the crisis described as a transitory blip in the continuing Great Moderation. Still that pales into insignificance compared to this piece by Casey Mulligan of Chicago (h/t commenter Daniel ), in which (I swear this is true!) the crisis is the result of financial markets correctly anticipating the adverse labour market impacts of possible legislation under Obama, such as a health plan that might include means tests.

Via a CT reader, this “rather horrifying attempt to hold an academic journal criminally responsible”:http://www.ejil.org/pdfs/20/4/1952.pdf (PDF) for publishing a negative book review and then refusing to suppress it. As Joseph Weiler, the editor of the _European Journal of International Law_ describes the culmination of his saga:

… on 26 September 2008 I received a Subpoena to appear before a French Examining Judge in connection with an investigation of alleged criminal libel based on a complaint made by Dr Calvo-Goller essentially replicating the complaints in her first letter to me. … in libel cases, all investigations of the merits of the case are exclusively reserved for the Criminal Court itself and, therefore, as a direct consequence of the complaint being filed, it was necessary that I be referred to the Court for trial. The date for the trial has now been set for 25 June 2010.

The review (in the _European Journal of International Law_ ) is “decidedly pungent”:http://www.globallawbooks.org/reviews/detail.asp?id=298, but (without commenting on the legal aspects,which I know nothing about) it seems to my eyes to be well within the usual norms of academic book reviewing (where a general tendency towards back-slapping congeniality is leavened by occasional fits of vigorous criticism). Weiler asks that academics who are upset at Dr. Calvo-Goller’s novel approach to managing the fallout from negative book-reviews send letters of “indignation/support” by email attachment (preferably with letterhead and affiliation) to EJIL.academicfreedom@Gmail.com, especially if they are editors or book review editors for other journals. He also asks that people send scanned or digital copies of other caustic book reviews to this address, so as to demonstrate that Dr. Calvo-Goller’s unhappy experience at the hands of a critic is nothing unusual. As an occasional author of “uncomplimentary book reviews”:http://www.timeshighereducation.co.uk/story.asp?storycode=410105 myself, I encourage people both (a) to send such reviews in and (b) to link them in comments, especially if they are well written. I do wonder whether Dr. Calvo-Goller appreciated the notoriety that she would accrue through her actions; The _Chronicle_ already “has a piece”:http://chronicle.com/article/NYU-Professor-Faces-Libel/64370/ on this, _Inside Higher Ed_ won’t be far behind, and I wouldn’t at all be surprised at all if this story breaks out into the mainstream press.

Oh dear. Half of Greece is now protesting against the EU as the cause of budget cuts, and not, say, their own lying government(s), aversion to tax and an enormous black economy. They could even more logically protest about Goldman Sachs’ role in the affair. But no, it’s all the Germans’ fault.

Invoking the European statesman’s version of Godwin’s Law, Greece’s deputy prime minister Theodoros Pangalos says Germany never paid proper reparations following its occupation of Greece in 1941:

“They took away the Greek gold that was at the Bank of Greece, they took away the Greek money and they never gave it back. This is an issue that has to be faced sometime in the future,” Mr Pangalos told the BBC World Service.

“I don’t say they have to give back the money necessarily but they have at least to say ‘thanks’,” he added.
