It’s an upside-down world when it comes to age and social power. Maxims like “respect your elders” and “follow in your father’s footsteps” indicated a social orientation favoring experience and forebears. Cultural continuity came from younger people looking up to older people, with apprenticeships, mentoring, and internships reflecting this deference to seniority.

An interesting change has come in the modeling of society over the past few decades, namely the move from a generation gap to a fixation on youth to a reorientation on youth showing elders the way. Now, a study from the Pew Research Center indicates that older adults are adopting social media quickly, with those 50-64 years old picking it up at an 88% greater rate in just one year. Overall, 47% of people in this age group now use social media, up from 25% in April 2009.

Email is still the favorite online technology for people 50 and older, with 89-92% using it daily.

The researchers attribute the appeal of social networks in these older age groups to a few factors:

  • Renewing connections for social support, fun during retirement, or second careers
  • Increased likelihood of living with a chronic disease, with social networks providing important support
  • Connecting with younger members of a family, bridging the generation gap

My question is, “Will that generation gap close in the next 10 years?” After all, the first part of Generation X is going to turn 50 next year, and the Generation Y denizens are approaching 30 years of age. As someone born in the early years of Gen Xers, I have to remind myself that I’m officially five years away from being in this 50-64 year old cohort now — that little insouciant voice I acquired in the nascent days of the Internet, when I was a fringe member of the Young Turks and the oldsters were out of touch . . . well, they’ve learned, and we’ve aged. And now, we’re all inhabitants of the Interwebs.

The Internet is quickly becoming the norm for all age groups. May it was just a matter of time — literally.

And maybe we’re even more likely than our predecessors to model our behavior on acting young through technology.

Have you paid your income tax this month ?

Recently, the city fathers in Philadelphia began bringing local blogs under existing small business ordinances, asserting that money-making blogs are, in fact, small businesses. (In the story linked above, these financial powerhouses made $50/year in one case, $11/year in another.) Federal tax returns shared with the city showed that Philadelphia bloggers were claiming income from blogs generated within city limits, giving someone at city hall the bright idea that a tax revenue opportunity lay in their midst.

It seems a logical argument, and the registration fee of $50/year or $300/lifetime isn’t extravagant. And, unlike some who are calling this a “blogging tax,” the fact is that existing small business licensing and income tax provisions are being applied to blogs that make money. (Note: New York City has a similar tax on small businesses, but it exempts the first $3,400 of tax liability, a smart move.) So, while it’s not a “blogging tax” per se, in practice it is picking out a new class of business for taxation.

Correcting the misconception that Philadelphia has levied a “blog tax” has preoccupied many, including the Guardian, which states:

But there is no blog tax. Philadelphia levies a licence fee on small businesses, which is no more a tax on bloggers than the UK’s VAT is a tax on chocolate buttons.

But chocolate buttons aren’t as complicated as blogs. Two problems arise when laws written for traditional small businesses are applied to blogs:

  1. Most blogs — even those that try to make money — don’t make enough to cover the relatively small ($50/year) business fee Philadelphia wants to impose
  2. Most blogs are exercises of freedom of speech, while most small businesses are not

By combining the chilling effect of taxes that might exceed incomes, thus forcing some blogs to cease operations, combined with the type of conduct blogs inherently engage in — namely, expression of ideas — the big question will come down to issues about freedom of speech.

Earlier this year, a Texas tax law designed to make it more difficult to operate strip clubs was struck down when exotic dancing was found by an appeals court to be protected by the First Amendment:

While nude dancing ‘falls only within the outer ambit of the First Amendment’s protection,’ it is nevertheless protected as expressive conduct.

If dancing without clothes on is protected from new taxes, can something within the inner ambit of the First Amendment be protected from taxation policy that could purposely or accidentally eliminate free speech?

Of course, newspapers and other publications have to pay taxes, but they are usually larger entities and not run by individuals. Again, this is why a carve-out for very small businesses makes sense.

I’ll bet this goes to court, and when it does, Philadelphia will have a hard time defending its practice as it exists. People within city limits who sell on eBay or who sell corn from their gardens each summer probably aren’t forced to register or pay annual registration fees — either because the city doesn’t go after them, or they don’t report the modest income on their taxes.

And registration is another vulnerability here. By forcing bloggers to register with the city, a perceived intrusion by the government could be argued. In fact, a political blogger in Missouri suggested that one Congressional candidate might like the idea of the registration and taxation scheme. It seems he’s trying to silence two bloggers in his area by filing complaints with the Federal Election Commission. So, clearly, the notion of using tax policy and registration requirements to chill free speech is occurring to people in the political realm.

Blog software is free. Blogging is free speech. Well, except in Philadelphia at the moment, where any blog with a small widget of Google ads or an infrequently trafficked Amazon storefront might find itself forced to consider whether $11/year and the urge to blog is worth another $39 in local small business fees.

Free speech indeed.

Penn & Teller, the most amazing magician tandem of our era, are also incredibly smart guys. Now, while Carl Sagan may have been the urbane ambassador of science, Penn & Teller demonstrate here their potential to be the rock stars of science communication. Warning: A few very well-placed swear words are used, but they are f-ing appropriate to anyone who has been as outraged by this nonsense as I’ve been over the years.

Enjoy!

Happy Friday.

The Research Information Network recently published a study evaluating the use and role of e-journals in UK researchers’ professional lives. It builds on an earlier study of the computer logs of researchers in the UK by adding interviews, observations, and an online questionnaire so that the earlier findings could be placed in context.

The study focused on researchers, not on practitioners or information consumers. This more tight-knit group always differs somewhat in their behaviors, being more voracious in their information consumption habits. The researchers who were studied came from a wide swath of fields — biological sciences, chemistry, environmental sciences, history, economics, and physics. This is a big problem with the study, actually. The mix makes it really hard to draw firm conclusions for any specialist group.

So, this is an interesting study of UK researchers, but nothing earth-shattering.

The good news is that journals are more important in the professional lives of researchers than ever. But how journals are accessed and used has changed significantly.

Among many interesting findings is that these researchers do much of their research outside of normal office hours, with some laughing outright at the suggestion that there are “normal office hours” anymore.

One major finding of the study is that e-journals are the primary way of accessing the journal literature. Another is that access to journals has improved dramatically. As the researchers state:

. . . few barriers to academic literature were identified by [interviewees] and many prized the extent of academic literature available and the mechanisms to provide access to those articles and papers not readily accessible online.

Passwords were the least of the researchers’ concerns when it came to barriers to access. Most often, a lack of subscription was cited as the reason for access problems, ahead of having to pay for a download. This suggests that the expectation is on the institution to provide access, not on the publisher (or on content being free). From the vantage point of these employees, it might look as if their employers are not providing what they need to do their jobs.

There are plenty of other stimulating findings in this paper:

  • Web of Science is the preferred portal for most researchers, except historians, who like JSTOR
  • Publisher portals don’t fare well as search starting points — ScienceDirect, Proquest, Embase, and the like barely register, with ScienceDirect doing the best, equivalent to a publisher site or journal site as a search starting point
  • Individual journal home pages rarely surface important articles

Generally, researchers are dealing with too much information, and feel there’s “too much literature being produced.” The abundance of articles and other demands created “too many time constraints militating against full and considered reading.” As a coping mechanism, researchers are “skimming and dipping” more than ever — not a new observation, but apparently the behavior is becoming more prevalent.

Print is peripheral for these researchers — not the print that comes out of their laser printers, but the bound magazines of old. Only 12.5% of their regular awareness of research comes from non-online sources (mostly colleagues and meetings, 2% via print), and only 11.9% said they’d recently discovered an important article via a print journal.

One theme should bother publishers both large and small — the low usage their sites get, even the major portals that publishers like Elsevier and Springer have created. The study shows that, at least in the UK, researchers visit these far less often than the true aggregators like Web of Science, PubMed, Google Scholar, and Google. The big plays like ScienceDirect don’t perform much better than a plain old journal home page, and some do much worse. It brings to mind the entire notion of the big Web site build yet again, and how potentially futile it is to create anything but something simple, straightforward, and designed for established aggregators and Web 2.0 realities.

I also got the feeling while reading this study that I was back in 1998, but reading a rehash of the story we were telling then. Maybe it’s just a matter of seeing some notions and predictions and trends come true, a kind of intellectual anticlimax, but the overall effect was a sort of deja vu.

The world has moved on for researchers in the UK. They have great access to academic materials, they use online resources heavily, they rarely derive value from print, and they prefer comprehensive aggregations to even big publisher silos.

Really, is anybody surprised by this?

It’s not easy being an expert these days, it seems. Every time you turn around, there’s someone challenging you, raising an objection, making a point. And the proliferation of channels has the potential to not only thin your message but level the playing field with antagonists.

But are experts worth defending from the onslaught of the new information economy?

In an article earlier this summer in the New York Post, David Freedman, obviously pimping his book “Wrong: Why Experts Keep Failing Us–and How to Know When Not to Trust Them,” talks about the pace of change in the medical literature in particular, assigning a reliability problem to a high-churn publishing environment in which frequent, novel findings are prized over infrequent and/or non-novel results. This pursuit of novelty to fill hectic publishing and academic schedules erodes trust in a cumulative fashion as refutation, disputation, and uncertainty emerge in a literature supposedly bent on producing something approximating the truth. And it goes beyond the medical literature, into the ubiquitous split-screens of television shout shows and the blogosphere:

Most people just don’t know how to pick it out from the constant stream of flawed and conflicting findings — the housing market is recovering, the housing market is getting worse, video games deaden children’s brains, video games boost rapid thinking. That’s why much of the public has simply stopped listening to experts, and sometimes with potentially catastrophic results, as when parents don’t get their children recommended vaccines and treatments, or believe they can eat whatever they want, or invest their savings in whatever stocks seem exciting.

The problem returns to filter failure — yet again. But which filter is failing?

That’s a harder question to answer.

There is a common sense filter that all journals sometimes fail, their staffs seduced by some combination of relationships, reputation, and results. There are the uncertainties of study design, study execution, results analysis, researcher rigor, and statistical analysis. In other words, there are problems with doing and reporting science that a research report can elide, minimize, or obscure, either consciously or accidentally. Teasing these out is something that can thwart even the best editors. As Michael Gazzaniga has written:

. . . to separate the verifiable from the nonverifiable is a conscious, tedious process that most people are unwilling or unable to do. It takes energy and perseverance and training. It can be counterintuitive. It is called analytical thinking. It is not common and is difficult to do. It can even be expensive. It is what science is all about. It is uniquely human

Then there’s the filter of peer-review, rife with well-known flaws and limitations. Amplifications and syntheses of research results — the media, surveillance publications, abstracts read in isolation, and interviews with authors — can further complicate results reporting and create unwarranted impressions in the minds of readers and the general public. And more outlets for authors means their enthusiasm for their findings can overwhelm the more measured findings in the source article.

And every channel creates an opportunity for a naysayer or critic or skeptic to appear.

In the era of abundance, traditional filters may be overwhelmed, and experts are looking a bit beat up. And it’s not just abundance, but the tone that abundance has assumed — disputatious, restless, and relentless. A RAND paper covered in the Publishing Frontier blog talks about the extra steps of “bulletproofing” that experts have to attend to in an increasingly vocal and polarized information sphere:

To some of us who were trained to believe that the most important part of the QA process is the scientific peer review, this can sometimes be an alien concept. Of course, the scientific peer review is the sine qua non; the science must speak. But if controversy lurks, bulletproofing is essential. This involves thinking in advance about the political lines of attack against the results and then identifying individuals who might come from those political quarters. Such individuals should be brought into the review process.

Left unprotected in a world filled with relentless demagoguery and spin, experts can flee, become reluctant to engage, and have gaps exposed by unfriendly forces.

Or perhaps experts are a vestige of a mass media age of scarcity, where information imbalances were captured by a select few and exploited for power. In a provocative essay, J.P. Rangaswami writes that the Web is relieving asymmetries in information creation and access, education, and design, all positives overall. So, while expertise may be viewed as eroding, in fact this erosion is part of a leveling function in which experts have to compete in a more dynamic, less authoritarian information environment based on abundance:

There’s been a lot of talk about the web and the internet making us dumber. I think it’s more serious than that. What the web does is reduce the capacity for asymmetry in education. Which in turn undermines the exalted status of the expert. The web makes experts “dumb”. By reducing the privileged nature of their expertise.

Of course, facts are still facts. Or are they? Virginia Heffernan, writing in the New York Times’ column “The Medium,” reflects on the quaint art of fact-checking — how it was done, how it has changed, how “Google became the only thing,” and how fact-checking has become part of everyone’s everyday life now, with some worrisome side-effects:

. . . fact-checking has assumed radically new forms in the past 15 years. Only fact-checkers from legacy media probably miss the quaint old procedures. But if the Web has changed what qualifies as fact-checking, has it also changed what qualifies as a fact? I suspect that facts on the Web are now more rhetorical devices than identifiable objects. But I can’t verify that.

Were we smarter with more books on the shelves and a cadre of experts leading us into the future? Or are we smarter with overlapping, exchanged, shared, compounding, sometimes confusing information available widely, with experts diminished or disposable?

This seems to be a debate that will only be settled with the passage of time.

Or is the expert of the future the one who finds a way to have it all?

The Fall of the Berlin Wall, 1989. The photo s...
Image via Wikipedia

People often say that an era is “bookended” by certain events — one ushering it in, the other closing it out. You could argue that the Cold War was bookended by Kruschev pounding his shoe on the table at the United Nations and the fall of the Berlin Wall. You could argue that the 1970s were bookended by the breakup of the Beatles and the appearance of HIV.

But what do you say when an era is bookended by actual books?

C.W. Anderson, a teacher at the College of Staten Island, writes in the Atlantic about putting together a syllabus for a course on “Print Culture.” In so doing, he notes:

Now that the electronic word has become embedded in our lives, we have a new perspective on what might have been special and specific about the last few hundred years of information dissemination.

That is, the Internet, e-readers, email, text messaging, and so forth may have effectively placed the terminal bookend on the print era, so that now we can examine what was special about the era defined by the print book and its offshoots.

Of course, print isn’t dead, and it won’t ever be gone, but its cultural centrality has diminished and continues to move to the periphery. However, Anderson’s syllabus shows us what the culture of print contributed to the advancement of our intellectual lives, as this selection shows:

  • Weeks 3-4: From Orality to Literacy to Print
  • Week 5: The Invention of the Author
  • Weeks 7-8: Copyright
  • Week 9: The Print Network — Bookstores, Libraries, Google
  • Weeks 12-13: The End of Print?

The books Anderson has chosen for his class are fairly definitive, a property of books themselves — the best historical books can provide a firm foundation for future scholarship. The notion of widespread, shared knowledge is another debt we owe to the power of multiple copies with high fidelity to the original — a concept most familiar with the book, but used again and again for movies, records, and so on.

Anderson is wise in his assessment of how media and culture interact and extend and mix:

I want to convince my students that different media cultures don’t replace each other in any sort of straight line. Rather, a culture of orality joins up with, and mixes with a culture of printing, which itself mixes with (but is not vanquished by) digital culture, and so on.

As a teacher and essayist, Anderson is straddling the eras himself, using books as references but introducing blogs and online articles to challenge them. His Atlantic article is highly enriched by links that could not have existed in print. His approach is completely modern, normal in today’s communication environment, and displays exactly the kind of mixing he talks about.

Two other recent articles discuss why the book as a print artifact is so troubled, poised on a precipice. Mike Shatzkin observes and/or argues in a recent post that while the print book was essentially perfected hundreds of years ago, e-books are improving regularly. Reactionaries who claim they will never give up the printed book are neglecting this important aspect. As Shatzkin writes:

. . . the insistence by some people that they will “never” give up the printed book — which leads to rather ludicrous glorification of the smell of the paper, ink, and glue and the nonsensical objections that the screen would be unsuitable for the beach (depends on the screen) or the bathtub (I can’t even imagine what the presumed advantage of the printed book is there) — must ignore the fundamental dynamic. Print books aren’t getting better. Ebooks are.

I recently observed this exact dynamic with visitors at our house. In a discussion of an obscure recipe, the “book lovers” scurried off to find something in the cookbooks. Their question as they left — “What’s your best book for recipes?” — elicited my answer of “My iPhone.” They scoffed, one saying, “We like books too much.” Sure enough, I had the answer before any of the book users. The tools available to the book users were the same ones as always — an index, page numbers, a table of contents, some section tabs (these were cookbooks). But the iPhone, like other e-readers, is facile now, and only getting better. The books I was competing against were the same as they were in the 1970s or 1990s.

A recent article in the New York Times observes that users of e-readers may also have a social advantage — the technology of the e-reader is intriguing, so people with iPads and Kindles get attention from strangers who want to touch, hold, gaze upon these new devices. Some users believe these devices are erasing the social stigma about reading alone in public. It’s an arguable point, as the article notes, but there definitely is something unique about a device (either the Kindle or the iPad) that can hold many types of content. With a book, it’s clear you’re reading one thing. With an e-reader, you have many more options at your fingertips, and that’s more socially interesting.

But while there may be some social benefit to e-books, one nagging concern about e-readers and the digital information experience in general was summed up nicely by author Jeanette Winterson:

If you start taking books off shelves then you are only going to find what you are looking for, which does not help those who do not know what they are looking for.

Browsing is still a problem with e-readers and online reading in general. Feeds, email alerts, and other techniques can help, but there’s nothing like wandering a bookstore, where you can experience the slow seduction, seeping inspiration, or random connection of real books. So while Shatzkin may be right that e-books and e-readers are improving, the macro book environment could suffer severely during the shift. Books could become files that are just plain hard to find. The marketing challenge of e-books aren’t well-addressed by the current devices.

The print era may be winding down, but many of the cultural transformations it wrought will be with us forever, shaping our journey. We are building from books, not destroying them. And as e-readers evolve, it’s interesting to ponder what the wireless information era will bring us. In a few decades or centuries, what will the syllabus of a class entitled “Connected Culture” look like?

CAPTCHA: gimpier CLIVE
Image by engineroomblog via Flickr

CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a commonly deployed technology used to increase the security around access controls, especially when there’s something at stake. You’ve certainly seen CAPTCHA systems before — distorted letters, letters behind grids, or letters half reversed out of circles. The goal is to make it difficult or impossible for hackers or spammers to automate machines to break into CAPTCHA sites, but to make it easy for humans to use.

In an impressive in-depth analysis of how CAPTCHA works, the automated attempts to defeat it, and the increasingly effective technique of paying human workers to overcome it, a group of researchers at the University of California, San Diego, show that economic trade-offs currently define how effective CAPTCHA systems are.

The technology works, but cheap labor markets have transformed its utility into its vulnerability.

Spammers like to set up validated email accounts, and the more of these they have, the better their returns. Hackers like to have dozens or hundreds of ways to access payment systems and other access control systems, making them porous.

As the researchers show, automated attacks on CAPTCHA systems leave the balance of power firmly in the defenders’ realm — it’s expensive to create sophisticated image manipulation and OCR programs but cheap for a CAPTCHA site to change its approach if it notices something amiss; the accuracy rate of automated recognition is about 30% at best, further reducing the ROI on what is an expensive and repeated investment in programming; and automated attacks are easier to detect. Overall, CAPTCHA has resisted automated attacks, as it was designed to do.

However, for CAPTCHA to work, humans have to be able to solve it at a rate of about 90%. Otherwise, it poses too much of a barrier. And this is what spammers and hackers are exploiting.

The researchers to a terrific job detailing how the labor market for human CAPTCHA entry has evolved over the past few years. Initially, for each 1,000 CAPTCHAs solved, a worker might make $10. Now, the going rate is closer to $1 or $2 per 1,000 CAPTCHAs solved, and in some cases, it’s as low as $0.75/1,000.

Combined with the high accuracy of these solves (75-90%), the ROI on using “human solver systems” to generate CAPTCHA solves is quite good. As a result, business has been growing — and moving to cheaper labor markets.

This downward price pressure reflects the commodity nature of CAPTCHA solving. Since solving is an unskilled activity, it can easily be sourced, via the Internet, from the most advantageous labor market—namely the one with the lowest labor cost. We see anecdotal evidence of precisely this pattern as advertisers switched from pur- suing laborers in Eastern Europe to those in Bangladesh, China, India and Vietnam.

Like any service provider market, quality providers are more expensive while commodity brokers are cheaper. Analyzing eight service providers, the researchers find that while the general trends are the same across them, the accuracy rate of some justifies their expense. Moreover, as sites institute more sophisticated CAPTCHA systems, the high-end providers (such as one called ImagedToText) become all the more necessary:

. . . the results for ImageToText are impressive. Relative to the other services, ImageToText has appre- ciable accuracy across a remarkable range of languages, including languages where none of the other services had few if any correct solutions (Dutch, Korean, Vietnamese, Greek, Arabic) and even two correct solutions of CAPTCHAs in Klingon.

The researchers conclude that while CAPTCHA is viewed by many as a technology, the way in which it depends on humans solving puzzles has made it vulnerable to a labor market solution:

. . . we have argued that CAPTCHAs, while traditionally viewed as a technological impediment to an attacker, should more properly be regarded as an economic one, as witnessed by a robust and mature CAPTCHA-solving industry which bypasses the underlying technological issue completely.

Overall, this is a fascinating paper that touches on many issues — security, access controls, economics, and technology — that are front and center in today’s publishing and services world.

Conrad II, Holy Roman Emperor
Image via Wikipedia

Recently, BioMed Central’s Virology Journal published a case report speculating that the woman in the Biblical story in which Jesus cures her of fever was suffering from the flu. The case report was obviously quite tongue-in-cheek, akin to many others in the literature, but also applied clinical reasoning to the scant evidence offered by the Bible.

In most case reports that seek to plumb historical facts, investigators review documentation, try to translate what they can into modern meaning, then attempt a diagnosis, usually for the sport of it. From gout in the Holy Roman Emperor to stroke in Woodrow Wilson to the death of King Edward VI, many journals allow researchers this kind of indulgence from time to time.

However, while the editors of Virology Journal seemed initially tickled by this traditional sort of academic and intellectual sport, the blogosphere was not. Very quickly, after a firestorm on the blogs (examples here and here) and across social media in general, the article was retracted, with a revealing comment from the editor-in-chief:

I wish to apologize for the publication of the article entitled ”Influenza or not influenza: Analysis of a case of high fever that happened 2000 years ago in Biblical time”, which clearly does not provide the type of robust supporting data required for a case report and does not meet the high standards expected of a peer-reviewed scientific journal. . . . Whilst only ever intended as an opinion piece and also a bit of relief from the ‘normal’ business of the journal, the speculations contained within this article clearly would be better expressed outside the confines of a peer-reviewed journal.

Even when publishing an article to provide a bit of “relief,” I guess you can’t mess with the sacrosanct, be it peer-review or Jesus.

While part of the problem may be that a religious document is probably not the best place to search for clinical evidence, the real problem seems to have been caused by the real-time Web and social media. As one of the authors noted in a published email about the events:

I was especially astonished that so many comments were made outside the scope of the journal. In medical writing, colleagues would usually make comments in the “letter to the editors” and the authors would respond in the subsequent correspondence. I once again am very sorry to have caused inconvenience to the Journal and anxiety to myself. I think I will never write this type of article any more – not worth the hassles!

I’ll wager that the authors and editors expected this little bit of fluff to pass quietly into oblivion, a harmless lark in an obscure journal. It’s not an unreasonable expectation. In the traditional journal world, reports like this were shielded from widespread evaluation due to relatively small circulations in tight-knit communities. Even in the last decade, the lack of robust commenting on journal articles has helped insulate scholars.

Today, things are different. Now, a science blogosphere bent on sensationalism and hungry for topics is perfectly willing to pick up on a silly article and beat the bejeezus out of it.

It’s worth noting that the authors of the speculative case report are mostly from China and Hong Kong (one blogger believes that how the abstract is written reveals the authors to be devout Christians, but I think that’s a real stretch). Whether their backgrounds intensified or blunted sensitivity to the religious dimensions of their historical case cogitation isn’t clear, but the fact that publication in a Western journal led to de facto censorship based on social media pressures says something negative about publication in the West and the culture following journals.

People do science. Every once in a while, they’ll play with its conceits and boundaries. Bloggers and social media denizens should keep their senses of humor. There was nothing here to get all feverish over. It was just a bit of fun.

Living in New England, I’ve become a fan of the roundabout, rotary, or traffic circle. While it’s always a bit nerve-wracking to venture into one, the fact is that you can feel your attentiveness increase, your speed decrease, and your safety improve. Studies have shown that traffic circles are not only incredibly safe because they make drivers watchful and properly nervous — they also make life safer for pedestrians.

A recent experiment in turning off traffic lights in one UK town is worth watching.

Drive safely this Friday the 13th. And remember — sometimes, the solution is to undo a prior solution.
