The Press Will Be Outsourced Before Stopped

Vin Crosbie, on the challenges, financial and otherwise, that newspaper publishers are facing: "The real problem, Mr. Newspaperman, isn't that your content isn't online or isn't online with multimedia. It's your content. Specifically, it's what you report, which stories you publish, and how you publish them to people, who, by the way, have very different individual interests. The problem is the content you're giving them, stupid; not the platform its on."

Travels In Numerica Deserta

There's a problem in the drug industry that people have recognized for some years, but we're not that much closer to dealing with it than we were then. We keep coming up with these technologies and techniques which seem as if they might be able to help us with some of our nastiest problems - I'm talking about genomics in all its guises, and metabolic profiling, and naturally the various high-throughput screening platforms, and others. But whether these are helping or not (and opinions sure do vary), one thing that they all have in common is that they generate enormous heaps of data.

Disrobing the Emperor: The online “user experience” isn't much of one

Now that the Web labor market is saturated and Web design a static profession, it's not surprising that 'user experience' designers and researchers who've spent their careers online are looking for new worlds to conquer. Some are returning to the “old media” as directors and producers. More are now doing offline consulting (service experience design, social policy design, exhibition design, and so on) under the 'user experience' aegis. They argue that the lessons they've learned on the Web can be applied to phenomena in the physical and social worlds. But there are enormous differences...

Second Life: What are the real numbers?

Clay Shirky, in deconstructing Second Life hype: "Second Life is heading towards two million users. Except it isn’t, really... I suspect Second Life is largely a 'Try Me' virus, where reports of a strange and wonderful new thing draw the masses to log in and try it, but whose ability to retain anything but a fraction of those users is limited. The pattern of a Try Me virus is a rapid spread of first time users, most of whom drop out quickly, with most of the dropouts becoming immune to later use."

The democratisation of everything

Over the last few years we've seen old barriers to creativity coming down, one after the other. New technologies and services makes it trivial to publish text, whether by blog or by print-on-demand. Digital photography has democratised a previously expensive hobby. And we're seeing the barriers to movie-making crumble, with affordable high-quality cameras and video hosting provided by YouTube or Google Video and their ilk... Music making has long been easy for anyone to engage in, but technology has made high-quality recording possible without specialised equipment, and the internet has revolutionised distribution, drastically disintermediating the music industry... What's left? Software maybe? Or maybe not."

RNA Interference: Film at Eleven

Derek Lowe on the news that the Nobel Prize for medicine has gone to Craig Mello and Andrew Fire for their breakthrough work: "RNA interference is probably going to have a long climb before it starts curing many diseases, because many of those problems are even tougher than usual in its case. That doesn't take away from the discovery, though, any more than the complications of off-target effects take away from it when you talk about RNAi's research uses in cell culture. The fact that RNA interference is trickier than it first looked, in vivo or in vitro, is only to be expected. What breakthrough isn't?"

PVP and the Honorable Enemy

Andrew Phelps: "Recently my WoW guild has been having a bit of a debate on the merits of Player-vs.-Player (PvP) within Azeroth. My personal opinion on this is that PvP has its merits, and can be incredible fun, but the system within WoW is horridly, horribly broken. It takes into account the concept of the battle, but battle without consequence, without emotive context, and most importantly, without honor..."

From later in the piece: "When I talk about this with people (thus far anyway) I typically get one of two responses, either 'yeah, right on!' or 'hey, it’s war, and war isn’t honorable – grow the hell up'. There is a lot to be said for that argument – but the problem is that war in the real historical world has very different constraints that are utterly absent from fantasized worlds..."
by Andrew Phelps in Got Game

Rats Rule, Right?

Derek Lowe: "So, you're developing a drug candidate. You've settled on what looks like a good compound - it has the activity you want in your mouse model of the disease, it's not too hard to make, and it's not toxic. Everything looks fine. Except. . .one slight problem. Although the compound has good blood levels in the mouse and in the dog, in rats it's terrible. For some reason, it just doesn't get up there. Probably some foul metabolic pathway peculiar to rats (whose innards are adapted, after all, for dealing with every kind of garbage that comes along). So, is this a problem?.."

Really BAD customer experience at Albertsons Market

Bob Jacobson, on shopping at his local Albertsons supermarket where he had "one of the worst customer experiences" of his life: "Say what you will about the Safeway chain or the Birkenstock billionaires who charge through the roof for Whole Foods' organic fare, they know how to create shopping environments that create a more pleasurable experience, at its best (as at Whole Foods) quite enjoyable. Even the warehouses like Costco and its smaller counterpart, Smart & Final, do just fine: they have no pretentions, but neither do they dump virtual garbage on the consumer merely to create another trivial revenue stream, all for the sake of promotions in the marketing department..."

The Guardian's "Comment is Free"

Kevin Anderson: "First off, I want to say that I really admire the ambition of the Guardian Unlimited’s Comment is Free. It is one of the boldest statements made by any media company that participation needs to be central to a radical revamp of traditional content strategies... It is, therfore, not hugely surprising to find that Comment is Free is having a few teething troubles..."

Woodpecker Punditry--Predicted and Delivered!

Email This Entry

Posted by Carl Zimmer

woodpecker-slide.gifOn Thursday I predicted that pundits would make the rediscovery of the Ivory-billed woodpecker an opportunity to criticise predictions that humans are causing mass extinctions--while conveniently ignoring evidence that goes against their claims. Today I came across the first case I know of, which appears a short Week-in-Review piece about the woodpeckers in the New York Times. (You have to scroll down a bit to the article.)

First, a conservation biologist is quoted saying that most things that scientists think are extinct are extinct. The article then ends with this:

But Stephen Budiansky, the author of several books on natural history, said the discovery points out how uncertain the business of predicting extinctions of species great and small - mostly small - can be.

All of the big numbers we have heard, of tens of thousands of extinctions worldwide, are not based on field observations," Mr. Budiansky said. "They're based on very simplistic mathematical models. But there's a huge gap between those predictions and the numbers of species we can actually confirm are extinct."

Budiansky's name may be familiar to you, especially if you followed the link to a paper by Stuart Pimm I provided in the last post. In the early 1990s, Budiansky was one of the first people to float the idea that North American birds demolish estimates of the current extinction rate based on habitat loss. Budiansky didn't actually make these claims in a scientific paper, but first in an article for U.S. News and World Report, and then later in a book, Nature's Keepers. In the paper I linked to, Pimm explicitly cites Budiansky's claims, and then proceeds to show that they are wrong. Fast forward some ten years. In that time Budiansky has, as far as I can tell from my search, never responded to Pimm's paper in a scientific journal or magazine. Nevertheless, he's still ready to hold forth about extinctions. I suppose he's trying to be controversial, but from his quote, you'd think that conservation biologists made these mathematical models in some smoke-filled back room and kept them a sworn secret. But you just need to look at Pimm's paper, or any other in this area, to see that they've always been upfront about using mathematical modeling to make predictions--just as a chemist uses mathematical models to make predictions about a chemical reaction, or a meteorologist uses models to predict the weather next week. But there's also been a long tradition of fieldwork (and experiments) to test the assumptions of the model. As for the huge gap between predictions and numbers of species we can actually confirm are extinct, if Budiansky wants to bankroll the millions of field biologists who would be needed to track the fate of all the millions of species on Earth over the next 200 years, I'm sure no conservation biologist would complain. But until then, our knowledge will have to remain imperfect.

(For those who want more: 1. Stuart Pimm gave an interesting talk on all this a couple years ago, and the transcript and audio file are available here. 2. For a similar case of flimsy "skepticism" about extinctions, see this post.)

What comes to my mind is "there are no white ravens", in terms of the logical difficulties of studying extinction. You can easily prove that there *are* white ravens by finding one, dead or alive. But you can never 100% prove that there is no such thing, because it's always possible that you missed it, or blinked at the wrong moment, or the albinism gene was entirely in a heterozygous state this generation, or somesuch. You can be 99.999% sure, but that takes a lot of effort, and you'll never be truly 100% sure.

You can't ever really *prove* a species extinct, and spectacular returns from presumed extinction such as the ivory-bill or the coelocanth remind us of this. But at the same time, those are exceptions to the rule, and most species listed as extinct truly are dead.

Still, most such pundits are products of the US public school system, can therefore can't be expected, on average, to understand such things.

"huge gap between those predictions and the numbers of species we can actually confirm are extinct"

the bad smell here is the convenient inference people will make that this means the same thing as "huge gap between predictions and number of species which are extinct". I can't help but feel this is being deliberately suggested.

of course, the best bet we have for those actual numbers is always going to be the best scientific model.

Two things occured to me while reading the post. First, they "balanced" the opinion of a conservation biologist with an author of several natural history books as if they carried equal weight and had equal expertise in the subject.
Second, they are deriding mathmatical models (shades of climate change contrarians) yet if there was no math involved how quick would they be to say it was unscientific. Seems to me like they are trying to have their cake and eat it too.
