New software provides free framework for collaborative research in visual field analysis

New software provides free framework for collaborative research in visual field analysis [ Back to EurekAlert! ] Public release date: 9-Jul-2013

Rockville, Md. Vision researchers have developed new software that will analyze visual fields in an open-source platform to improve and encourage collaborative research among independent labs. An analysis of the free tool is presented in a Journal of Vision (JOV) paper, The visualFields package: A tool for analysis and visualization of visual fields.

In the paper, authors introduce and demonstrate the visualFields package, which can work separately or in conjunction with the Open Perimetry Interface an open-source software developed by Andrew Turpin, PhD, and described in a previous JOV article (The Open Perimetry Interface: An enabling tool for clinical visual psychophysics). The interface allows researchers to operate commercially available instruments called perimeters that are designed to examine the visual field of patients.

"With open-source resources like these, research can be conducted in a completely transparent manner," said author Ivn Marn-Franch, PhD, of the University of Valencia (Departamento de ptica at Universitat de Valncia) and formerly of Indiana University School of Optometry. "And unlike with most proprietary software, results can be verified and methods more closely scrutinized by independent researchers."

The visualFields package contains analytical and visualization tools, including methods for detection and follow-up of glaucoma. To demonstrate the visualFields package, the research team used the right eye of a patient with glaucoma who participated in the Bloomington longitudinal study. Results included four examples of visual field analysis along with the corresponding code used for their generation.

"The necessity for moving from proprietary software into a fully open-source framework has been in the psyche of the glaucoma research community for many years," said Marn-Franch. In looking at the future, he and his colleagues suggest that Open Perimetry Initiative (OPI) would allow groups or individual researchers to test their models with large datasets of real data that they would not have access to otherwise. They also propose centers with good infrastructure would be able conduct clinical trials using state-of-the-art methods for analyzing their data right away and without incurring any cost.

"But, the success of OPI relies strongly on active collaboration from every end of the research community: Some by donating their datasets, some by donating the implementations of their research methods," cautions Marn-Franch.

The researchers make clear that the visualFields package is not intended to replace well-tested, commercially available stand-alone software; rather, it is meant to be an environment for experimentation and research that is free and open for scientists to use and offer ways to improve upon it.

Final Fantasy VII Available on Steam | Video Game Blog, Video ...

Published: 04 July 2013 2:14 PM UTC

Posted in: News, PC, PC News, Video Games

Tags: Final Fantasy VII, Megan Steinberg, News, PC, Steam

As of this morning you can now purchase Square Enix?s Final Fantasy VII on Steam for $11.99 or ?9.99.

This is a long-awaited release that Square Enix had been promising for quite a while, and we?re happy to inform you Steam gamers that you can now immerse yourself in the JRPG goodness of Final Fantasy VII through the power of Valve?s online software.

The game was originally released in 1997 for the original Sony Playstation console, and was the first of the Final Fantasy series to become as popular as it did, and it paved the way for an incredibly successful series of games and a worldwide franchise.

If you purchase and download a copy of Final Fantasy VII you?ll be happy to know that Steam Achievements have been added for the game, and it will use Cloud saving and storage so you can play it wherever and whenever you wish. Unfortunately this download is only available on PCs and not for Macs, hopefully a Mac version will become available in the future.

Square Enix have said previously that, despite popular demand, they will not be doing a full remake of the classic game because they are still aiming to release a Final Fantasy game ?of the same standard.? However, Final Fantasy fans can look forward to a few coming releases: Final Fantasy XIV, the MMORPG instalment for the series, will be rereleased in August for PC and PS3; later this year Final Fantasy X and X-2 will be rereleased in HD quality and February 2014 will see the release of Lightning Returns: Final Fantasy XIII.

So if you just can?t wait for these releases, get onto Steam and download Final Fantasy VII.

Green panel stays construction at Noida landfill site | Magicbricks ...

Delhi/NCR

The National Green Tribunal has stayed construction activity on the landfill site in Sector 123 here after a commission appointed by it found that the project had been formulated without following the guidelines. The Noida Authority has also been restrained from carrying out digging or construction till the next hearing.

The principal bench of the tribunal headed by its chairman, Justice Swatanter Kumar, imposed the stay based on the local commissioner?s report on the landfill?s distance from human habitations. The Authority officials are yet to appear before the tribunal to clarify their stance despite getting court notices. The commission filed its report ?TOI has a copy? with the tribunal on July 2.

The commission found that the Authority had started construction on the site without obtaining the mandatory approval from Uttar Pradesh Pollution Control Board (UPPCB). Habitations, including villages, residential sectors and ongoing housing projects, were found to be in proximity to the site on all sides in clear violation of the norms.

A petition had been filed by Go Green Welfare Association, a Noida-based organization of residents and homebuyers. Advocate Sumeer Sodhi had been appointed as commissioner by the tribunal. The report was prepared after Sodhi inspected the site on May 25 in the presence of senior Authority officials, including project engineers and the health department officials, UPPCB officials and representatives of the residents? association.

The petitioners had alleged that the site chosen was amid habitations, which is in violation of the Municipal Solid Waste (Management & Handling) Rules, 2000. A landfill cannot be near a residential cluster, a state highway or a river.

In Venezuelan capital, a 'plague' of motorcycles

(AP) ? Ronald Alvarez was driving in chaotic, bumper-to-bumper traffic when he heard a throaty buzz and insistent "Beep! Beep! Beep!" approaching rapidly from behind.

Motorcyclists in Venezuela's capital are known for zipping between lanes and taking off side mirrors, either inadvertently or with malicious intent if they feel a driver hasn't left enough room. So Alvarez swerved to the side to open up space for this one, rear-ending a car that had slammed on its brakes in the process.

"It is the worst plague there is right now in Caracas," Alvarez fumed about the proliferation of motorcycles.

Alvarez's complaint is echoed by many residents of this capital of narrow streets, where the transportation infrastructure has been neglected for decades leading to traffic congestion so bad that it is almost always best navigated on motorcycle. A two-hour car drive to work can take less than half an hour on the back of a bike.

The two-wheel invasion began about a decade ago with the arrival of Chinese-made motorcycles that sell for just a few hundred dollars, and has since exploded, causing Caracas residents to rant at the locust-like swarms of motorcycles that blow through red lights and ignore one-way traffic signs with impunity, becoming a serious public health and safety issue.

Gangs of armed, two-wheeled political shock troops backed by the government terrorize voters and break up opposition protests. Motorcycles are also favored by robbers and hit-men, and are involved in 90 percent of violent crimes in this murderous city, according to an estimate by a prominent criminologist.

In 2011 the government finally passed a law that was supposed to help crack down on the lawlessness, but nearly two years later there's practically zero enforcement and people say the problem is only getting worse. For many the motorcycle has become a potent symbol of anarchy and ungovernability in a troubled nation.

"For me, the problem of motorcyclists has become a matter of public health," said Fermin Marmol Garcia, a criminologist who reached the 90 percent figure on motorcycles' involvement in violent crime by analyzing data from the government and NGOs. "It's no longer just a crime issue, a violence issue. It's a matter of public health."

Venezuela is the world's third-worst country for motor vehicle-related deaths with 37.2 per 100,000 inhabitants, according to a World Health Organization global road safety study published this year. Only the Dominican Republic and Thailand scored worse.

It's not clear how many of those involved motorcycles. But news of accidents are a constant on the radio, and one recent report said the more than a dozen hospitals in the capital treat at least 100 motorcycle injuries a week ? apiece.

Spend an hour or so on the streets of Caracas, and you might see every conceivable traffic rule broken.

Streams of up to 50 bikes zoom between lanes of motionless cars. Dozens park on the sidewalk, blocking pedestrians' passage. Families of four ride a single motorcycle. Bikers mass under overpasses during storms, choking off traffic.

"It's like people transform when they get on a motorcycle," said taxi driver Samuel Tarazon, who last year watched one flatten an elderly man in a crosswalk. "It's such a violent manner of driving."

Police largely look the other way and some say they are among the worst offenders. Many government motorcycles circulate without license plates and are apparently not even registered.

Part of the problem is that while the 2011 law bars all the violations listed above, a separate statute that would establish penalties has repeatedly been delayed. So even if a cop were inclined to stop a driver for riding without a helmet, he couldn't write out a ticket because there's no rule that says how much the fine should be.

Experts say motorcyclists' sense of impunity has helped drive an even more troubling trend, that of the vehicles being used to commit crimes.

Armed robbers on motorcycles regularly prey on helpless motorists caught in bumper-to-bumper gridlock, where police patrol cars have no way to respond to a call.

"I'm in a traffic jam and they go like this on the window," said Alvarez, imitating the sound of a gun butt tapping on glass. "What else can I do? I roll down the window. 'Give me everything you have.' Here you go, brother. I'm not going to risk my life for material belongings."

Motorcycle gangs have spread and made a tradition of forming boozy caravans after the funeral of one of their own, deliberately jamming up traffic to demand "contributions" from motorists or rob them outright.

Last month, in a case that shocked even calloused Caracas residents for its audacity, as many as 40 bikers in one such procession relieved dozens of drivers of their wallets, purses, laptops and cellphones on a main road in the suburb of Macaracuay.

Newspaper crime pages are full of accounts of murders carried out from bike-back. And earlier this year a 17-year-old Caracas girl was raped by two men after the mototaxi driver she hired delivered her to her attackers.

There are some signs that President Nicolas Maduro is serious about tackling the problem. He speaks much more frequently than his predecessor, the late Hugo Chavez, about combatting crime.

"The full weight of the law will fall upon anyone who does not adjust to the rules," Interior and Justice Minister Miguel Rodriguez Torres said last month.

Authorities said recently they are negotiating with motorcycle clubs on the language of the regulations.

Some of the gangs have powerful political ties, having been encouraged by the government to organize after a failed coup attempt against Chavez in 2002.

When Chavez died this March, one such gang roughed up students who had been protesting near the Supreme Court. A month later, around election day, militants on motorcycles threw a firebomb into a political party office and vandalized a bakery they said belonged to an opposition supporter.

"When you feed little monsters and those monsters grow, they take on a life of their own," Marmol Garcia said. "And perhaps ... the anarchy of the motorcycle union is a monster that today has great power and will cause great concern in the political establishment as it tries to rein them in."

For a case study Venezuela need look no further than neighboring Colombia, where motorcycles were once synonymous with drug cartel assassins. Authorities there have made significant strides by enforcing registration rules and helmet and reflective vest requirements, outlawing mototaxis and letting mayors prohibit motorcycle passengers during times of unrest.

There are about 275,000 registered motorcycles in Venezuela today, according to the most recent census in this nation of 28 million, though the true number likely exceeds 800,000, El Universal newspaper recently reported.

Yet the motorcycle boom has also made life easier for many and allowed countless Venezuelans to earn an honest living as drivers, couriers and so on.

Mototaxis, once essentially unheard of, await customers on every other street corner in the downtown business district. At rush hour everyone from working-class laborers to lawyers in business suits can be seen hopping on the back of motorcycles.

Henry Frias, a 35-year-old bank worker, frequently takes mototaxis to cut what would be an hour-and-a-half, 5-mile (8-kilometer) morning commute by bus, to just 15 minutes.

"I have to be there by 8:00 a.m., but with the stoplights and the traffic it's impossible," Frias said recently, dressed in gray slacks and a pressed white dress shirt. "It has its dangers because with a mototaxi you're often at risk of suffering any kind of accident ... but this is the surest way to arrive on time."

Gene mutations caused by a father's lifestyle can be inherited by multiple generations

Gene mutations caused by a father's lifestyle can be inherited by multiple generations [ Back to EurekAlert! ] Public release date: 1-Jul-2013

New research in The FASEB Journal suggests that moderate paternal exposures, such as cigarette smoking, can increase the number of mutations transmitted to their children, and even the next generation

Bethesda, MD -- Gene mutations caused by a father's lifestyle can be inherited by his children, even if those mutations occurred before conception. What's more, these findings show that mutations in the germ-line are present in all cells of the children, including their own germ cells. This means that a father's lifestyle has the potential to affect the DNA of multiple generations and not just his immediate offspring. These findings were published in the July 2013 issue of The FASEB Journal.

"Our study should be regarded as a pilot study," said Roger Godschalk, Ph.D., a researcher involved in the work from the Department of Toxicology and the School for Nutrition, Toxicology and Metabolism at Maastricht University in the Netherlands. "We hope that our findings support the initiation of new, more elaborate studies that investigate the role of daily life exposures on germ-line mutations transmitted to offspring."

To make this discovery, Godschalk and colleagues looked at two groups of families (father, mother and child) from the Norwegian Mother and Child Cohort Study. The first group had a low yearly income, whereas the second group had a relatively high yearly income. The investigators chose income as a criterion because it generally correlates to lifestyle choices of the parents. For instance, fathers in the low income group were more often cigarette smokers than fathers in the high income group. Researchers looked for DNA mutations in the children and found that they were more frequent in the group with low income fathers than in the group of high income fathers. These results suggest that the parents living conditions before conception may directly impact the health of their children.

"We've known for a very long time that preventive care among expectant mothers is critical to the health and well-being of their children," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "Now, we're learning that fathers don't get a free pass. How they take care of themselveseven before conceptionaffects the genetic makeup of their children, for better or worse."

Ariz. fire chief: Shelters are 'last-ditch effort'

PRESCOTT, Ariz. (AP) ? A fire chief says lightning sparked a number of wildfires near Prescott, Ariz., the day a nearby blaze killed 19 members of an elite "Hotshots" fire crew.

Prescott Fire Chief Dan Fraijo says he was assigned to another fire when he received a call Sunday afternoon from someone assigned to the deadly fire.

He says he learned 19 members of the Granite Mountain Hotshots had deployed their portable emergency shelters while battling the blaze near the small town of Yarnell.

Fraijo describes the shelters as a "last-ditch effort to save yourself."

One man on the 20-member Hotshot crew survived, and that was because he was moving the unit's truck at the time. Fraijo says the survivor "feels terribly, and we all feel terribly."

Terrance Roberts, Former Denver Blood: 'I Know Hundreds Of People Who Have Been Shot' (VIDEO)

In March, The Huffington Post began talking to teens and adults throughout the U.S. about their experiences with gun violence. This is one individual's story. You can read others here.

Two of the bloodiest mass shootings in American history have struck one state: the Columbine High School massacre in 1999 and the Aurora movie-theater shooting in 2012, both in Colorado. But the tragedies often overshadow the everyday gun violence of Colorado's gang activity, particularly in Denver.

"I honestly can't answer how many people I've known that have been shot or killed because I've known so many people," Terrance Roberts, a former Park Hill Blood gang member and now a leading anti-gang activist, told The Huffington Post. "It was a real war."

Beyond the tragic Aurora shooting, last year again saw a surge of gun violence, some of it gang related. The number killed in Denver in 2012 doesn't reach the heights of the gang violence in the '90s -- 41 people were killed, and of those, 23 were gun deaths. But in the first four months of 2013, gang-related violence has nearly doubled in Denver since the same period in 2012, with over 250 total gang-related incidents.

Some 200 organizations that authorities have linked to gang activity, including the better-known Bloods and Crips, have existed for years in Denver and its surrounding areas. Though Mile High City is not immediately associated with gangs, they have left a violent wake, taking the lives of hundreds and wounding countless more since gang activity began to noticeably grow in Denver in the early 1980s.

The number of gang-related homicides has decreased in Denver since the peak during 1993's "summer of violence" and the years surrounding it, but residents of the areas where gangs have historically dominated are still haunted by their experiences, and wary about fresh outbreaks of violence.

"I've witnessed people get murdered in front of me over $5 dice games, being ambushed, ran up on over gang violence -- I've been shot twice myself. I probably know easily, maybe 70 people or more who have been murdered due to gun violence, not even the stabbings, just shootings," Roberts, the activist, recounted.

"How many people do I know that have been shot?" he added. "Hundreds. Right here in Northeast Denver. Hundreds of people."

Roberts joined the Park Hill Bloods as a freshman in high school and was in jail just a few years later, at 18 years old.

Now a 36-year-old father, he's turned his life around. In 2005, he founded the Prodigal Son Initiative in Park Hill, the same area where he ran with the gang, to mentor at-risk youth. With the group, he is trying to help organize a community still plagued by gangs and gun violence, both past and present.

But he remains both physically and emotionally scarred.

"I was shot in my back during the summer of violence in 1993," Roberts said. "I was selling crack one night, probably with about $1,200 in my pocket -- I'm 16 or 17 years old -- all these crackheads were coming, I was selling all this crack and I was taking all my money out of my pockets and I turned on the light and stood up and some guys hopped out of the bushes and sprayed me."

Roberts says the shooting left him with a cracked pelvic bone, a ruptured spleen and shredded upper and lower intestines. After multiple surgeries, Roberts has a noticeable scar across his abdomen. Although he has largely healed from the shooting, the complications still cause sickness; the scar tissue around his intestines causes bowel obstructions and severe dry heaving.

Roberts suffers from what he describes as something similar to post-traumatic stress disorder, a severe form of anxiety that many members of the military experience when returning from combat.

"To this day it scares me for cars to pass me," Roberts said. "Even last night I was driving, it was dark, and this car had loud music and I could hear it. You could tell it was probably some young guys, or some gangsters. Waiting at the light, these guys pulled up almost beside me and I was sitting in my car afraid, and this is trauma, and I was hoping these guys don't shoot me in my car and kill me. But you know, the light turned, I turned left and they kept going their own way."

"When I hear loud bangs, I flinch," he said. "Those types of things -- pretty much PTSD kind of trauma."

Roberts said this trauma continues to impact a survivor for his or her entire life, snuffing out potential.

"Seeing my friends who I know who have been gunned down or been around it, seeing how they live, seeing what it did to them, how they have to function now, and that's the pain they still have in their life -- we're talking about just normal, regular people, they could have worked for The Huffington Post, they could be reporters right now," Roberts said. "They aren't stupid people, they are just traumatized people."

The shooting death of Denver Police officer Celina Hollis during a jazz concert at City Park last July -- in broad daylight and in plain view of bystanders -- brought back memories of Denver's gang violence in the '90s. Twenty-one-year-old Rollin Oliver was charged with Hollis' murder. In testimony, he revealed that he was fleeing from a group of Crips who were shooting at him during the concert.

Oliver was from the same Park Hill neighborhood where Roberts grew up -- known Blood territory surrounded by neighborhoods occupied by rival Crip gangs. Oliver's own affiliation with the Bloods was disputed by his attorney, who claimed that his client was not a member of a gang at the time of the City Park shooting.

The violence culminated most recently during April's "420" marijuana celebration at Civic Center Park in Denver, when two rival gang members shot and wounded three people.

There's still much work to be done in Denver. Troubled neighborhoods like those in Park Hill are still in the early stages of a turn-around, as Joel Warner has written about in detail in his "Up From The Ashes" work for Westword.

But groups like Prodigal Son are also struggling for other reasons. Earlier in 2013, Roberts announced that due to lack of funding, the organization may have to close its doors this year. Many fear that such losses could cause a major setback to any progress made so far.

"Any time you have African-American men going back into the community to mentor young African-American males, it makes an incredible difference," City Councilman Albus Brooks told The Denver Post of the potential end of Roberts' work. Brooks' district includes Holly Square in Park Hill.

As Brooks said, "No one can measure their impact on young people's lives in northeast Denver."

Internet Explorer 11 to support WebGL and MPEG Dash

Few would say that consistency is good for its own sake. Microsoft certainly agrees -- it just revealed at Build that Internet Explorer 11 will reverse the company's previously cautious stance on WebGL. The new browser will support the 3D standard from the get go, joining the likes of Chrome and Firefox. IE11 should improve plain old 2D as well, as there's hardware acceleration for video streaming through MPEG Dash. All told, Internet Explorer should be a better web citizen -- and deliver a speed boost in the process.

Improving materials that convert heat to electricity and vice-versa: Turning waste heat into electricity

May 5, 2013 ? Thermoelectric materials can be used to turn waste heat into electricity or to provide refrigeration without any liquid coolants, and a research team from the University of Michigan has found a way to nearly double the efficiency of a particular class of them that's made with organic semiconductors.

Organic semiconductors are carbon-rich compounds that are relatively cheap, abundant, lightweight and tough. But they haven't traditionally been considered candidate thermoelectric materials because they have been inefficient in carrying out the essential heat-to-electricity conversion process.

Today's most efficient thermoelectric materials are made of relatively rare inorganic semiconductors such as bismuth, tellurium and selenium that are expensive, brittle and often toxic. Still, they manage to convert heat into electricity more than four times as efficiently as the organic semiconductors created to date.

This greater efficiency is reflected in a metric known by researchers as the thermoelectric "figure of merit." This metric is approximately 1 near room temperature for state-of-the-art inorganic thermoelectric materials, but only 0.25 for organic semiconductors.

U-M researchers improved upon the state-of-the-art in organic semiconductors by nearly 70 percent, achieving a figure-of-merit of 0.42 in a compound known as PEDOT:PSS.

"That's about half as efficient as current inorganic semiconductors," said project leader Kevin Pipe, an associate professor of mechanical engineering as well as electrical engineering and computer science. Pipe is a co-author of a paper on the research published in Nature Materials on May 5, 2013.

PEDOT:PSS is a mixture of two polymers: the conjugated polymer PEDOT and the polyelectrolyte PSS. It has previously been used as a transparent electrode for devices such as organic LEDs and solar cells, as well as an antistatic agent for materials such as photographic films.

One of the ways scientists and engineers increase a material's capacity for conducting electricity is to add impurities to it in a process known as doping. When these added ingredients, called dopants, bond to the host material, they give it an electrical carrier. Each of these additional carriers enhances the material's electrical conductivity.

In PEDOT doped by PSS, however, only small fraction of the PSS molecules actually bond to the host PEDOT; the rest of the PSS molecules do not become ionized and are inactive. The researchers found that these excess PSS molecules dramatically inhibit both the electrical conductivity and thermoelectric performance of the material.

"The trouble is that the inactive PSS molecules push the PEDOT molecules further apart, making it harder for electrons to jump between PEDOT molecules," Pipe said. "While ionized PSS molecules improve electrical conductivity, non-ionized PSS molecules reduce it."

To improve its thermoelectric efficiency, the researchers restructured the material at the nanoscale. Pipe and his team figured out how to use certain solvents to remove some of these non-ionized PSS dopant molecules from the mixture, leading to large increases in both the electrical conductivity and the thermoelectric energy conversion efficiency.

This particular organic thermoelectric material would be effective at temperatures up to about 250 degrees Fahrenheit.

"Eventually this technology could allow us to create a flexible sheet -- think of Saran Wrap -- that can be rolled out or wrapped around a hot object to generate electricity or provide cooling," Pipe said.

Jon Jones, Pat Healy and Sara McMann: UFC 159?s Three Stars

UFC 159 was a bizarre event ? possibly cursed by demons ? but there were still plenty of standout performances by fighters whose bouts ended normally. Who stood out for you? Speak up on Twitter or on Facebook.

No. 1 star -- Jon Jones: As we've said since the fight was made, Chael Sonnen was not the right competition for UFC light heavyweight Jones because he is middleweight coming off of a loss. Jones could have taken Sonnen lightly and still probably won, but he didn't do that. He used the fight as another opportunity to show his dominance, beating Sonnen at his own game by taking him down several times before finishing the fight near the end of the first round.

Would the fight have been stopped if they made it out of the first round, and the referee had noticed Jones' mangled toe? Who cares? It didn't happen, and Jones is still the champ.

No. 2 star -- Pat Healy: The UFC's already stacked lightweight division somehow got even tough with Healy's performance on Saturday night. Along with Jim Miller, he put on a show then finished the fight in the third round. He won both Fight of the Night and Submission of the Night, meaning Healy walked away with an extra $130,000.

No. 3 star -- Sara McMann: As an Olympic silver medal-winning wrestler, McMann is one of the most decorated athletes to join the UFC. This means she had big expectations to perform, and she exceeded them. McMann used wrestling and power to stop Sheila Gaff in the first round.

1 in 4 jobless in Spain

MADRID (AP) ? With over 6 million unemployed for the first time ever, Spain's jobless rate shot up to a record 27.2 percent in the first quarter of 2013, the National Statistics Institute said Thursday, in another grim picture of the recession-wracked country.

The agency said the number of people unemployed rose by 237,400 people in the first three months of the year, a 1.1 percent increase from the previous quarter. The total out of work stood at 6.2 million people, the first time the number has breached the 6-million mark.

Unsurprisingly, the details of the report make for grim reading.

The number of people considered long-term unemployed ? out of a job for more than a year ? increased to 3.5 million while the unemployment rate for those aged under 25 was a staggering 57 percent. The government body also said its survey found the number of households without any one working had risen by 72,400 to a 1.91 million.

"The situation is really bad, with all the cuts that there have been, there are families that are going through a bad time because a lot of families have all the members unemployed and they don't have any income," said shop assistant Rodrigo Limpias , 30.

Labor Ministry employment secretary Engracia Hidalgo described the figures as "dramatic" but said the government was working non-stop to try make Spain a job creator once again.

Spain has been in recession for much of the past four years as it struggles to deal with the collapse of its once-booming real estate sector in 2008. In the previous decade its economy was thriving, generating millions of jobs.

In just over a year in office, the conservative government has launched a series of financial and labor reforms and pursued a raft of spending cuts and tax increases that have managed to reduce a swollen deficit. Even so, the country had the highest budget deficit among the 17 European Union countries that use the euro in 2012.

"This is getting worse every day. (The government) has no solution, there are more and more people unemployed and we don't have enough to eat," said Maria Carmen Huerta, 55, an unemployed IT worker.

The government's handling of the crisis has sparked almost daily protests.

On Thursday, 1,400 police were to be deployed around Parliament and the building was totally cordoned off ahead of an evening demonstration. Parliament cancelled its session for the day but blamed reasons other than the rally.

Several previous rallies close to Parliament have ended in clashes with police. The Interior Ministry said police arrested four people and confiscated material they believe was to be used to start fires at bank offices in the city. The ministry claims violent, anti-establishment groups are behind the rally.

Prime Minister Mariano Rajoy has acknowledged that 2013 will be a bad year but insists that it would have been worse without the reforms. The International Monetary Fund indicated last week that Spain's economy will contract by 1.6 percent this year.

The government is predicting that Spain will return to growth, which should help the labor market. Rajoy has promised reforms to be presented Friday that will "make the economy more flexible, more competitive and will turn those predictions around."

Opposition parties said the unemployment figures highlight how Rajoy's austerity policies are damaging the economy.

"6 million people unemployed is 6 million reasons for the government to withdraw the labor reform and change its economic policy," said Oscar Lopez of the leading opposition Socialist party.

But the EU's top economic official, Commissioner Olli Rehn said "Spain should maintain the reform momentum by including comprehensive and concrete policy measures" in its programs.

He said that "despite significant progress in 2012, there are still excessive macroeconomic imbalances" with high domestic and external debt continuing to pose risks for growth and financial stability.

Teaching tool could improve emergency training worldwide

New, low-tech teaching techniques used by novice instructors may improve training for healthcare providers in performing cardiopulmonary resuscitation (CPR) on children who suffer cardiac arrest. Researchers in a large multicenter study say their findings hold the potential to standardize and upgrade life support training by hundreds of thousands of instructors around the world.

"In the U.S. alone, over 8,000 children a year have a cardiac arrest, but providers may encounter such a catastrophic event only once or twice in their careers," said the study's senior author, Vinay M. Nadkarni, M.D., a critical care and resuscitation science specialist at The Children's Hospital of Philadelphia. "So it's crucial to keep those front-line providers trained and ready to respond. This new approach will assist with that."

The research team carried out the EXPRESS study in 14 research centers in North America, publishing their results online April 22 in JAMA Pediatrics. The EXPRESS (Examining Pediatric Resuscitation Education Using Simulation and Scripted Debriefing) researchers found that trainees in simulation exercises using a child-sized mannequin retained more knowledge if the crisis simulation leaders used scripted debriefings.

"A debriefing is the most important part of a simulation experience, and gives participants an opportunity to reflect on what they did right and what needs improvement," said Adam Cheng, M.D., of Alberta Children's Hospital and the University of Calgary. Cheng, the study's principal investigator, added that, "In a scripted debriefing, the words and sentences are phrased in a very deliberate way that helps learners reflect and think analytically about their performance and about handling emergency situations."

Nadkarni noted that the teaching method, called "advocacy inquiry," is designed to pull out a rationale from students to explain their decisions. "This avoids the common teaching technique of 'guess what I'm thinking.' We've taken a sophisticated interactive teaching method and distilled it into a script that can be readily used by novice instructors."

Many of the instructorsphysicians, nurses, emergency medical technicians and paramedicsare not highly experienced teachers. But they have a broad reach: some 280,000 instructors teach these programs around the world, typically to a group of 10 trainees each. In North America, about half a million health care workers take the Pediatric Advanced Life Support (PALS) course per year, featuring emergency simulations on lifelike mannequins.

In the current study, the largest ever conducted involved pediatric simulation, 387 participants in 90 teams followed a 12-minute long scenario in which a 12-month-old infant suffers cardiac arrest. After the teams responded to the simulated emergency, half the instructors debriefed their group with an assigned script, and the other led unscripted debriefings. The debriefing session lasts 20 minutes. As assessed in tests and quizzes, participants in the scripted groups had improved medical knowledge and rated their instructors more highly, compared to unscripted groups.

In addition to comparing scripted to nonscripted debriefing, the researchers also compared "high-realism" to "low-realism" simulation. In the high-realism groups, the instructors used SimBaby, a computerized infant mannequin, with all the functions active, such as heart sounds, blood pressure, and breath sounds; in the low-realism groups, most of SimBaby's functions were turned off.

Using the high-realism simulation didn't provide educational advantages over the low-realism simulation. This may have important practical implications, said Nadkarni, because the high-realism simulators cost roughly $30,000 each as opposed to $300 to $400 for the simplest model. "If these results are generalizable, they imply that we can improve resuscitation training with less investment in expensive simulators," he added.

One limitation of the current study, concluded Nadkarni, is that it measured educational outcomes, not clinical outcomes in patients. Further research will determine how well the improvements in education translate into better care and better outcomes for children.
