Measuring the Intensity of Elections – from Guardian Tech

‘Twindex’ wants to gauge Election 2012’s intensity: will it be successful?

With the launch of its new Twitter Political Index, Twitter is hoping to give denizens of the 24-second news cycle a clear insight into the campaign.

Using data from social media analysis service Topsy, the tool – shorthand: ‘Twindex‘ – will sift through its daily dispatch of some 400m tweets, then sort the tweets according to thousands of keywords meant to indicate positive or negative thoughts toward President Obama or Republican challenger Mitt Romney. The resulting daily Twindex is a two-person leader board you see pictured above.

On Thursday, Obama was up 10 Twindex points from the day before, while Romney was up one. From this, can we infer that both candidates did well with prospective voters Wednesday?

Not really, according to researchers.

Tom Rosenstiel leads a of team of Pew Research Center analysts who’ve spent a year monitoring campaign conversations on social media at the center’s Project for Excellence in Journalism. Rosenstiel said that, for now, all Twitter is likely to do is gauge the conversation amongst a young, more wired-in and “self-selected” group of users. In other words, they tend to be the opposite of the disengaged, less politically aligned people whose votes tend to win elections.

Another defining characteristic?

“Overall, what we see is that people tweet when they’re irritated about something.”

Sentiment analysis on Twitter as a concept is not a new endeavor, but attempts to actually build tools that predict the future (or even figure out the present) are small in number. In January, the Washington Post’s Mention Machine took a stab at analyzing tweets ahead of the Republican primaries to determine the winner. While conversation around most of the candidates flagged and spiked, the Machine consistently churned out results indicating that one GOP candidate was ahead of the field.

“If Twitter were a good predictor of public attitudes,” Rosenstiel told the Guardian, “Ron Paul would be the Republican nominee. Not Mitt Romney.”

Cory Haik, executive director of digital news at the Washington Post, said Twindex is a more complicated next step in the progress toward figuring out social media analysis. Where the Post’s creation attempted to help reporters and editors craft a narrative from a real-time intake of tweets, Twitter is taking it further by using technology that professes to be better at sorting what comes in.

“By providing more signals, more dials – that can agree or disagree – these new technologies give a more complete picture of crafting a political forecast,” Adam Sharp, head of government, news and social innovation at Twitter, told the New York Times on Wednesday.

“This is a million times more complicated and detailed,” Haik told the Guardian. “[Mention Machine] did the job we wanted it to. I think what they’re putting out there feels like they’re getting at it in a better way.”

The road to November will tell us whether a Twitter-powered analysis tool can present users with the winner ahead of Election Day. But, in the end, the sheer use numbers still don’t lie in Twitter’s favor. Twitter only accounts for15% of American adults who are online, and about half of them use the service daily. Twitter ranks last out of 19 information sources people use to get campaign news, according to a February report by Pew – that puts the little blue bird behind cable news networks, talk radio shows and religious television and radio.

And don’t forget: with months to go, there’s the chance of burnout – if we’re not there already.

“People don’t love the campaign,” Rosenthiel said. “Twitter is a wonderful platform for monitoring discussion in real-time, which is not something everyone wants to do. You might actually say, ‘Well, I got enough information … so maybe Twitter’s not the place I want to follow.”

Amtrak Follies Continued

From the Economist

Rail renovations

The most expensive tunnel in the world

Jul 29th 2012, 17:28 by N.B. | WASHINGTON, D.C.

EARLIER this month, Amtrak, America’s government-owned passenger rail corporation, released a plan outlining how it’s going to spend $151 billion it doesn’t currently have (and has no prospect of receiving anytime soon) to bring true high-speed trains to America’s crucial Boston-New York-Washington rail axis. Gulliver has already explained why Amtrak’s project is ambitious, expensive, and unlikely. But the more you delve into the details of the plans, the sillier they appear.

Take, for example, Amtrak’s proposal to bore a 10-mile rail tunnel underneath Philadelphia. As Steve Stofka, a transport blogger, explains, this proposal would require the most expensive type of tunnel imaginable—”It is freaking expensive to bore a ten-mile-long tunnel through an alluvial floodplain under a highly urbanised area—and to maintain it, since it will reside below the water table,” Mr Stofka writes. At $10 billion, he notes that the project would be about three times as expensive per mile as theGotthard Base Tunnel under the Swiss Alps. And all this is for marginal improvements in speed and access. The tracks around and through Philadelphia aren’t, generally, big obstacles to high-speed rail—the tunnels in and around Baltimore, Maryland are. It would be much cheaper to replace Baltimore’s terrible tunnels than to build a fancy new one under Philadelphia.

 

 

The Philadelphia tunnel, unfortunately, isn’t even the worst part of Amtrak’s plan. That honour goes to a $7 billion renovation of Washington’s Union Station (pictured), which Slate‘s Matthew Yglesias rightly calls“insane”. Amtrak’s cost estimate is many times higher than for similar projects in Europe. And as Mr Yglesias notes, it seems that Amtrak doesn’t have its priorities straight:

[F]rom the look of Amtrak’s proposal in addition to the high unit costs problem, there seems to be an awful lot of emphasis on doing stuff that has no really clear operational benefits. For example, they don’t like the fact that right now Union Station’s existing platforms have unsightly and inconvenient columns in the middle of them. To get rid of the columns, they need to scrap the 2,000-space parking deck that they’re supporting. Then they want to replace the parking deck with a 5,000-space four-level underground garage. That’s an awful lot of money to spend on something that has minimal operational value from the standpoint of actually operating a railroad.

There’s no doubt that America’s big east-coast cities could benefit from access to true high-speed rail. But before it gets the funding necessary to make that happen, Amtrak should put forth a credible, smart proposal that puts the needs of passengers and the public first. I have taken Amtrak trains out of Union Station several hundred times. I’ve never given more than a moment’s thought to the “unsightly and inconvenient” columns on the platforms, but I have noticed how trains crawl through the tunnels in Baltimore and move much more slowly, overall, than similar trains in Europe. Renovating Union Station and replacing its parking garage isn’t likely to make Amtrak’s trains go any faster. Amtrak needs to get a handle on which kind of projects are worth billions of taxpayer dollars—and which aren’t.

 

The Toughest Olympic Event

From the Wall St. Journal

Toughest Olympic Event: Turning a Profit

By Jack Hough

During this Summer Games, a gifted few will run short bursts at over 25 miles per hour, lift triple their body weight overhead or jump nearly eight feet into the air. But no one will ever be talented enough to calculate a precise financial return on London’s Olympic investment.

If someone could do the math, evidence suggests the return would almost surely be negative. That’s OK. Weddings have negative financial returns, too. People still like them.

Mayors should stop pitching the Olympics to voters as a money-maker, and call hosting for what it is: A chance to blow $10 billion to $20 billion on brief joy and a generation of fond memories. That’s less than the cost of a midsize bank bailout or three months of war. I’ll take the high-jumping, thanks.

The main reason for applying to host the games, according to the International Olympics Committee, “lies in the possibilities for economic development and tourism inherent in such an event.”

But think of it: Football would be a lot less profitable if teams had to build new stadiums each season. Olympic hosts do the equivalent, while spending lavishly on security, public transportation and much else. Just putting together a bid for the games cost London $14 million.

The cost/benefit projections of Olympic hosts tend toward the creative. Many label the cost of construction as a beneficial “economic impact” that will multiply into future revenues. The current tenants of Beijing’s $480 million “bird’s nest” arena – if there were any — might point out the flaws in that approach.

True, Olympic host countries tend to enjoy a burst of economic growth after the games are done, but be careful telling cause from effect. Prospering countries are more likely than others to bid, after all.

A 2009 study by researchers at U.C. Berkeley and the Federal Reserve found that countries that lose a bid to host grow just as nicely as those that win. A 2010 study compared bid winners with losers and found “no long-term impacts of hosting” on economic growth or trade.

One of the authors of that study, Scott Holladay, an economist at the University of Tennessee, says that London will lose money on its investment, but not nearly as much as Beijing. Hosts that lose the least are generally those that already have much of the infrastructure in place, he says.

Los Angeles is widely believed to have turned a small profit in the 1984 games, but crucially, it was the only bidder for that year’s games. That helped it avoid what Mr. Holladay calls the downfall of most hosts: the “winner’s curse,” or the tendency of auctions to be won by those who pay too much.

The math doesn’t look good for Rio de Janeiro in 2016. Its winning bid came with a $14 billion plan that nearly totalled the sum of spending for the three competing bids. That’s $700 per taxpayer, or close to a month’s salary for an average worker. Rio’s best hope for containing costs may be in learning from some new building tactics used in London, including the use of temporary structures that can be downscaled or relocated after the games.

Mr. Holladay says the bidding process has become an arms race, and developing nations are increasingly using the games to showcase their arrival as economic powers, even though these countries are likely to see the largest financial losses as hosts. “We’ll see more Beijings and fewer L.A.s in terms of returns,” he says.

That would be a shame. In mixing in more developing nations as hosts, the International Olympic Committee should emphasize thrift, not extravagance, when reviewing bids. Hosting isn’t profitable, but it needn’t be squanderous, either.

Solar Power Helped Keep Lights on in India – Scientific American

Solar Power Helped Keep the Lights On in India

By David Biello | August 1, 2012 |

india-overloaded-gridEvery day, at least 400 million Indians lack access to electricity. Another nearly 700 million Indians joined their fellows in energy poverty over the course of the last few days, or roughly 10 percent of the world’s population.

Oddly enough, some of the formerly energy poor—rural villagers throughout the subcontinent—found themselves better off than their middle-class compatriots during the recent blackouts, thanks to village homes outfitted with photovoltaic panels. In fact, solar power helped keep some electric pumps supplying water for fields parched by an erratic monsoon this year.

That monsoon is partly to blame for the blackouts as well. A lack of rain has meant a reduction in power from India’s hydroelectric dams. Pair that with problems with the supply of coal to burn and the northern half of India found itself with not enough electricity supply to meet demand. One ironic anecdote illustrates this conundrum nicely: coal miners in northern India were trapped when their electric lifts failed as a result of the blackout exacerbated by a lack of coal.

The thirst for electricity stems from burgeoning demand from India’s middle class, which has embraced everything from air conditioning and the electric-powered subway trains of New Delhi. India also enjoys some of the highest rates of what is known in the trade as “non-technical losses,” i.e. people hijacking electric supplies and not paying for it (as opposed to “technical losses,” like the amount of electricity lost via the physics of transmission itself and the like.) And then there are the politically popular programs like providing free power to farmers for irrigation pumps.

Such politics no doubt played a role. Tensions between state governments, the national government and power suppliers are legion, including some areas that take more electricity than they are supposed to at times. That’s the reason the energy minister, newly promoted to minister for home affairs for his stellar performance, gave for the first day of blackouts. And politics have prevented the kind of investment in infrastructure maintenance and upgrades that can prevent things like power lines sagging in the heat andshorting out via untrimmed trees. Wait, does that sound familiar?

The root cause of the massive back-to-back blackouts won’t be known for a while. It took three months to definitively trace the root cause of the 2003 blackout that shut down the U.S. Northeast along with parts of Canada to the aforementioned. But one root cause is already obvious: a crippling indifference to the basic needs of electrical infrastructure (the Indian government has declined to invest in an upgrade to the country’s aging grid)—and people. That kind of sounds familiar too.

Rotating blackouts, brownouts and power cuts are all too common in India thanks to a shortfall of electricity, so much so that it is taken as the normal state of affairs and major companies like Wipro build their own micro-grids to cope. As is the fact that those 400 million Indians—and the more than 1 billion people around the world like them—still lack access to modern energy.

New Way to Fracture for Oil and Gas

Great News for the Enivronment!

A New Way To Fracture Oil and Gas Wells

By Brian Westenhaus | Tue, 31 July 2012 22:21 | 2

Benefit From the Latest Energy Trends and Investment Opportunities before the mainstream media and investing public are aware they even exist. The Free Oilprice.com Energy Intelligence Report gives you this and much more. Click here to find out more.

GASFRAC of Calgary, Alberta, Canada, has developed an innovative closed stimulation process and injection method, utilizing gelled LPG rather than water based conventional formation fracturing fluids.

The firm has developed a Liquefied Petroleum Gas (LPG) or propane based gel that is as natural to a well as soil is to the earth. It’s dissolves into the formation hydrocarbons improving performance without using water.

LPG will burn of course so GASFRAC has developed a zero-oxygen, closed system and specialized equipment that protects worker safety, eliminates post-job cleanup and requires only minimal flaring that can be reduced to zero when installing the appropriate recapture facilities.

Without forcing water into the oil or gas laden rock opens the ability to quickly recover 100% of the fracturing fluid resulting in enhanced oil and gas recovery and longer sustained production.  The LPG could be recaptured, reused or resold, a highly cost-effective benefit, especially for multi-stage horizontal wells.

GASFRAC is using your standard C3H8, a naturally occurring hydrocarbon that doesn’t damage the rock formation. In the gel form the material has low surface tension, low viscosity, low density, along with solubility within naturally occurring reservoir hydrocarbons – all of which when added together, create more effective fracture lengths, enabling higher initial and long-term production of the well.

GASFRAC LPG Fracking Fluid
GASFRAC’s LPG Frack Results Graphic.

These properties have what GASFRAC claims are major advantages.  The sand or proppant can be evenly distributed during pumping, thereby decreasing the chance of the proppant settling in odd inconvenient spots in the formations.  The gel can generate a higher pay zone height throughout pumping and subsequent long-term production.

The waterless method increases initial production rates, helping establish production much sooner than traditional fracturing methods.

Sounds like an advertisement. Nearly so . . .

Except that the gel regains permeability with the stimulated hydrocarbons, with the ability to recover 100% of the fracturing fluids within days of stimulation. This creates economic and environmental benefits reducing clean-up, waste disposal and pre and post-job truck traffic, while creating higher initial production levels. It is a true win for producers and a win for the environment.

The technology isn’t yet fully proven.  Still the firm has fracked over 1,300 wells in Canada and the US. The method was originally designed to improve the performance of low-pressure wells and has impressed those within the environmental arena.

The Vancouver Sun reports GASFRAC charges a 50 percent premium in comparison to traditional fracking companies.  But there would be significant savings in water use, truck traffic (as much as 75% less), and easier site cleanups. Apart from logistical gains, the article also referred to the rise in well production as “spectacular.” Reports from the Cardium formation, which is west of Edmonton, displayed that the LPG fracking results are “two to three times better” at increasing the flow of oil and gas in comparison to traditional methods.

Another environmental advantage is LPG is electrically neutral and lacks having much friction, so it doesn’t dissolve and bring back to the surface the salts, heavy metals or radioactive compounds that water-based fracking extracts from the rock underground.

The oil and gas business, in its natural ultra competitive way has been pretty hush-hush on the technology.

Last year, Chevron, one of the world’s largest oil and gas companies, used LPG to frack several natural gas wells in the Piceance Basin, home to several lucrative coal, oil and natural gas deposits in northwestern Colorado. The technology “significantly increases production while minimizing water usage,” the company said in its annual report, which did not mention GASFRAC by name.

It looks like there are already some formulas being developed for the gel for use in the specific circumstances.  That is proprietary, and GASFRAC is leaving the ownership of the formulas in the hands of the well operators.

That privacy drives the watchdogs a bit crazy.

The technology is marching on.  San Antonio-based BlackBrush recently announced a two-year contract with GASFRAC in the oil-rich Eagle Ford Shale in Texas. Phil Mezey, BlackBrush’s co-CEO, said in a news release that using LPG brought “oil production at a sustainable rate weeks earlier than with the standard water frac and we are seeing huge savings on disposal of frac fluids.”

GASFRAC has also fracked several oil wells in Colorado’s Niobrara Formation. Although GASFRAC hasn’t released the name of its customer, some investors have speculated that it is Fort Worth-based Quicksilver Resources.

The most interesting news is a well that GASFRAC fracked in north central Pennsylvania for Dallas-based Exco Resources. It could give a glimpse of how effective LPG fracking might be in the huge Marcellus shale in the environmentally and politically charged northeast.

The technology developed by former Chevron engineer Robert Lestz, now GASFRAC’s chief technology officer is very likely to take off.  The company recently recieved a $100 million loan that will help ease some of its growing pains, and it has hired Zeke Zeringue, a former president of Halliburton Energy Services Group, to replace its retiring founder and CEO.  Plenty of money, the right people and customers are lining up.

And!  They’re hiring!

For the less thoughtful – a cautionary note.  This is propane, the stuff in the bottle for the grill and used to fuel cars, heat homes and other things.  It obviously burns.  Yet a lot of folks are going to raise a ruckus over it being more dangerous than water.  Keep in mind that the oil and gas business is about flammable liquids and gases and as a practical matter no one else is better able to incorporate a propane technology.  It’s already safe and will get safer.  Ruckessing over propane to frak a well might seem a little daft.

Congratulations to Mr. Lestz.  Working out how to mix up a hydraulic fluid that works better than water and solves the big well fracturing concerns with better productivity is a fine accomplishment – that from here is highly appreciated.

Olympic Medals for Art and Culture – from the Smithsonian

When the Olympics Gave Out Medals for Art

In the modern Olympics’ early days, painters, sculptors, writers and musicians battled for gold, silver and bronze

At the 1912 Summer Olympics in Stockholm, American Walter Winans took the podium and waved proudly to the crowd. He had already won two Olympic medals—a gold for sharpshooting at the 1908 London Games, as well as a silver for the same event in 1912—but the gold he won at Stockholm wasn’t for shooting, or running, or anything particularly athletic at all. It was instead awarded for a small piece of bronze he had cast earlier that year: a 20-inch-tall horse pulling a small chariot. For his work, An American Trotter, Winans won the first ever Olympic gold medal for sculpture.

For the first four decades of competition, the Olympics awarded official medals for painting, sculpture, architecture, literature and music, alongside those for the athletic competitions. From 1912 to 1952, juries awarded a total of 151 medals to original works in the fine arts inspired by athletic endeavors. Now, on the eve of the 100th anniversary of the first artistic competition, even Olympics fanatics are unaware that arts, along with athletics, were a part of the modern Games nearly from the start.

“Everyone that I’ve ever spoken to about it has been surprised,” says Richard Stanton, author of The Forgotten Olympic Art Competitions. “I first found out about it reading a history book, when I came across a little comment about Olympic art competitions, and I just said, ‘what competitions?’” Propelled by curiosity, he wrote the first—and still the only—English-language book ever published on the subject.

To learn about the overlooked topic, Stanton had to dig through crumbling boxes of often-illegible files from the International Olympic Committee archives in Switzerland—many of which hadn’t seen the light of day since they were packed away decades ago. He discovered that the story went all the way back to the Baron Pierre de Coubertin, the founder of the IOC and the modern Games, who saw art competitions as integral to his vision of the Olympics. “He was raised and educated classically, and he was particularly impressed with the idea of what it meant to be a true Olympian—someone who was not only athletic, but skilled in music and literature,” Stanton says. “He felt that in order to recreate the events in modern times, it would be incomplete to not include some aspect of the arts.”

At the turn of the century, as the baron struggled to build the modern Olympics from scratch, he was unable to convince overextended local organizers of the first few Games in Athens, St. Louis and Paris that arts competitions were necessary. But he remained adamant. “There is only one difference between our Olympiads and plain sporting championships, and it is precisely the contests of art as they existed in the Olympiads of Ancient Greece, where sport exhibitions walked in equality with artistic exhibitions,” he declared.

Finally, in time for the 1912 Stockholm Games, he was able to secure a place for the arts. Submissions were solicited in the categories of architecture, music, painting, sculpture and literature, with a caveat—every work had to be somehow inspired by the concept of sport. Some 33 (mostly European) artists submitted works, and a gold medal was awarded in each category. In addition to Winans’ chariot, other winners included a modern stadium building plan (architecture), an “Olympic Triumphal March” (music), friezes depicting winter sports (painting) and Ode to Sport (literature).  The baron himself was among the winners. Fearing that the competitions wouldn’t draw enough entrants, he penned the winning ode under the pseudonyms George Hohrod and Martin Eschbach, leaving the medal jury unaware of the true author.

Over the next few decades, as the Olympics exploded into a premier international event, the fine arts competitions remained an overlooked sideshow. To satisfy the sport-inspired requirement, many paintings and sculptures were dramatic depictions of wrestling or boxing matches; the majority of the architecture plans were for stadiums and arenas. The format of the competitions was inconsistent and occasionally chaotic: a category might garner a silver medal, but no gold, or the jury might be so disappointed in the submissions that it awarded no medals at all. At the 1928 Amsterdam Games, the literature category was split into lyric, dramatic and epic subcategories, then reunited as one for 1932, and then split again in 1936.

Many art world insiders viewed the competitions with distrust. “Some people were enthusiastic about it, but quite a few were standoffish,” Stanton says. “They didn’t want to have to compete, because it might damage their own reputations.” The fact that the events had been initiated by art outsiders, rather than artists, musicians or writers—and the fact that all entries had to be sport-themed—also led many of the most prominent potential entrants to decide the competitions were not worth their time.

Still, local audiences enjoyed the artworks—during the 1932 Games, nearly 400,000 people visited the Los Angeles Museum of History, Science and Art to see the works entered—and some big names did enter the competitions. John Russell Pope, the architect of the Jefferson Memorial, won a silver at the 1932 Los Angeles Games for his design of the Payne Whitney Gymnasium, constructed at Yale University. Italian sculptor Rembrandt Bugatti, American illustrator Percy Crosby, Irish author Oliver St. John Gogarty and Dutch painter Isaac Israëls were other prominent entrants.

In 1940 and 1944, the Olympics were put on hold as nearly all participating countries became embroiled in the violence and destruction of World War II. When they returned, the art competitions faced a bigger problem: the new IOC president’s obsession with absolute amateurism. “American Avery Brundage became the president of the IOC, and he was a rigid supporter of amateur athletics,” Stanton says. “He wanted the Olympics to be completely pure, not to be swayed by the weight of money.” Because artists inherently rely on selling their work for their livelihood—and because winning an Olympic medal could theoretically serve as a sort of advertisement for the quality of an artist’s work—Brundage took aim at the art competitions, insisting they represented an unwelcome incursion of professionalism. Although Brundage himself had once entered a piece of literature in the 1932 Games’ competitions and earned an honorable mention, he stridently led a campaign against the arts following the 1948 Games.

After heated debate, it was eventually decided that the art competitions would be scrapped. They were replaced by a noncompetitive exhibition to occur during the Games, which eventually became known as the Cultural Olympiad. John Copley of Britain won one of the final medals awarded, a silver in 1948 for his engraving, Polo Players. He was 73 years old at the time, and would be the oldest medalist in Olympic history if his victory still counted. The 151 medals that had been awarded were officially stricken from the Olympic record, though, and currently do not count toward countries’ current medal counts.

Still, half a century later, the concept behind the art competitions lingers. Starting in 2004, the IOC has held an official Sport and Art Contest leading up to each summer Games. For the 2012 contest, entrants sent sculptures and graphic works on the theme of “Sport and the Olympic values of excellence, friendship and respect.” Though no medals are at stake, winners will receive cash prizes, and the best works will be selected and displayed in London during the Games. Somewhere, the Baron Pierre de Coubertin might be smiling.
