When political parties reverse their policy stance, their supporters immediately switch their opinions too

At least a significant portion of their supporters, according to U of Aarhus researchers.

When two competing political parties in Denmark reversed their policy stance on an issue — suddenly they both supported reducing unemployment benefits — their voters immediately moved their opinions by around 15% into line with their party.

The same thing happened when one of these parties shifted from opposing to supporting ending Denmark’s early retirement.

The researchers were studying how public opinion is formed. Their recent paper sheds light on how much influence political parties have over their supporters, according to the researchers, who surveyed their panel of subjects in five successive waves between 2010 and 2011. They studied the same group of party supporters before, during and after a policy reversal.

“We can see that [the] welfare programs were actually quite popular … and many of the voters of the center-right party were in favor of these welfare programs,” commented one of the researchers, Rune Slothuus. “Nevertheless, we can see that they reversed their opinion from supporting these welfare programs to opposing these welfare programs.”

“I was surprised to see the parties appeared this powerful in shaping opinions,” Slothuus said. “Our findings suggest that partisan leaders can indeed lead citizens’ opinions in the real world, even in situations where the stakes are real and the economic consequences tangible.”

The researchers pondered Western democracy in light of their findings: “If citizens just blindly follow their party without thinking much about it, that should lead to some concern about the mechanisms in our democracy. Because how can partisan elites represent citizens’ views if the views of citizens are shaped by the very same elites who are supposed to represent them?”

The brain listens for things it is trying to predict

The brain interprets sounds as they contrast with its expectations. It recognizes patterns of sounds faster when they’re in line with what it is predicting it will hear, but it only encodes sounds when they contrast with expectations, according to Technische U researchers.

Researchers showed this by monitoring the two principal nuclei of the subcortical pathway responsible for auditory processing: the inferior colliculus and the medial geniculate body, as their subjects listened to patterns of sounds which the researches modified so that sometimes they would hear an expected sound pattern, and other times something unexpected.

We have a particular way of understanding a room

When several research subjects were instructed to explore an empty room, and when they were instead seated in a chair and watched someone else explore the room, their brain waves followed a certain pattern, as recorded by a backpack hooked up to record their brain waves, eye movements, and paths. It didn’t matter if they were walking or watching someone else, according to UC researchers led by Dr Matthias Stangl.

The researchers also tested what happened when subjects searched for a hidden spot, or watched someone else do so, and found that brain waves flowed more strongly when they had a goal and hunted for something.

Extroverts and introverts use different vocabularies

Extroverts use ‘positive emotion’ and ‘social process’ words more often than introverts, according to new research conducted at Nanyang Technological U.

‘Love,’ ‘happy,’ and ‘blessed’ indicate pleasant emotions, and ‘beautiful’ and ‘nice’ indicate positivity or optimism, and are among the words found to be used more often by extroverts. So too are ‘meet,’ ‘share,’ and ‘talk,’ which are about socializing. Extroverts use personal pronouns — except ‘I’ — more too, another indication of sociability.

The correlation, however, was small, and the researchers think that stronger linguistic indicators need to be found to achieve their general goal, which is improving machine learning approaches to targeting consumer marketing.

WhatsApp is changing today - Users must give the app permission to send their private data to Facebook or lose account

WhatsApp was bought by Facebook in 2014, but has thrived while promoting itself as a privacy-respecting messaging app that now has 1.5b monthly active users. This week, though, WhatApp sent out an update to users’ phones that they must ‘consent’ to a new policy or lose access.

Whatsapp will now share more of your data, including your IP address (your location) and phone number, your account registration information, your transaction data, and service-related data, interactions on WhatsApp, and other data collected based on your consent, with Facebook’s other companies. Facebook has been working towards more closely integrating Facebook, WhatsApp, Instagram and Messenger.

Users who do not agree to ‘consent’ to the new policy will see their WhatsApp account become inaccessible until they do ‘consent.’ These accounts will remain dormant for 120 days after which they will be ‘deleted.’

The biggest change to the user policy, which many people ignored and clicked ‘agree’ to, thinking it was just another unimportant app update message, now reads,

‘We collect information about your activity on our Services, like service-related, diagnostic, and performance information. This includes information about your activity (including how you use our Services, your Services settings, how you interact with others using our Services (including when you interact with a business), and the time, frequency, and duration of your activities and interactions), log files, and diagnostic, crash, website, and performance logs and reports. This also includes information about when you registered to use our Services; the features you use like our messaging, calling, Status, groups (including group name, group picture, group description), payments or business features; profile photo, “about” information; whether you are online, when you last used our Services (your “last seen”); and when you last updated your “about” information.’

Notably, Elon Musk tweeted on the news, saying that WhatsApp users should switch to Signal, one of several popular privacy-focused messaging apps similar to WhatsApp.

The data sharing policy change doesn’t affect people in Europe due to GDPR data protection regulations.

President Trump silenced on top social media platforms after mob storms Capitol

The US president was locked out from posting new messages on his Facebook and Twitter accounts after an unruly group of supporters assembled outside the capitol building where Biden’s election win was being confirmed.

The lockdown on Twitter lasted 12 hours until the president removed tweets Twitter said violated its ‘civic integrity policy,’ but Zuckerburg said that Trump would be silenced on Facebook and Instagram for at least two more weeks until his presidential term was over. Facebook and Twitter are two of the main ways the president communicates with citizens and the world.

It is the first time social media platforms have chosen to limit the free speech of such an important figure.

Trump’s tweets from Jan 6, 2020, as recorded by thetrumparchive.com

Many news organizations covered the story using language such as ‘Trump Incites Rioters.’

Following Trumps ‘ban,’ there was renewed talk about treating social media platforms, where people share informative content, as publishers themselves, in part because their algorithms amplify things shared when those things are engaging. There was also talk about how the social media platforms that censored the president’s content did so as a response to content or events but without first drawing their ‘red line’ and saying which content is and isn’t allowed on their platforms.

Some of Trump’s staff resigned following the incident at the Capitol building, and there were also a lot of questions why the national guard wasn’t capable of handling the incident properly.

UPDATE January 8: Twitter permanently banned Trump’s account. Google removed Parler, an app like Twitter used by Trump supporters, from the Android app store to make it harder for people to download it, saying Google requires social media apps to have content moderation policies to remove posts that incite violence.

The problem is that in order to disinfect a bus, train, sports hall, or plane by chemical spraying, you need physical manpower, and in order for the spraying to be effective, you have to give the chemical time to act on the surface,” according to the lead researcher of the Tel Aviv U team who worked on the research, Professor Hadas Mamane. “Disinfection systems based on LED bulbs, however, can be installed in the ventilation system and air conditioner, for example, and sterilize the air sucked in and then emitted into the room.”

That light kills viruses has long been understood and it is already used for this purpose. The team’s work showed, however, the optimal type of LED light to specifically inactivate Conoavirus. Notably, they found that cheaper, more common 285nm LED bulbs are almost as efficient as 265u bulbs. The cheaper bulbs kill 99.9% of the virus in under half a minute, the team showed. The research is expected to have commercial applications.

“We discovered that it is quite simple to kill the Coronavirus using LED bulbs that radiate ultraviolet light,” explained Mamane. “We killed the viruses using cheaper and more readily available LED bulbs, which consume little energy and do not contain mercury like regular bulbs. Our research has commercial and societal implications, given the possibility of using such LED bulbs in all areas of our lives, safely and quickly.”

It’s important to note that regular people shouldn’t just try to use LED light to disinfect things without understanding the dangers involved. LED, light other types of light, can be harmful to people when not handled safely.

The research was published in the Journal of Photochemistry and Photobiology.

When political parties reverse their policy stance, their supporters immediately switch their opinions too

At least a significant portion of their supporters, according to U of Aarhus researchers.

When two competing political parties in Denmark reversed their policy stance on an issue — suddenly they both supported reducing unemployment benefits — their voters immediately moved their opinions by around 15% into line with their party.

The same thing happened when one of these parties shifted from opposing to supporting ending Denmark’s early retirement.

The researchers were studying how public opinion is formed. Their recent paper sheds light on how much influence political parties have over their supporters, according to the researchers, who surveyed their panel of subjects in five successive waves between 2010 and 2011. They studied the same group of party supporters before, during and after a policy reversal.

“We can see that [the] welfare programs were actually quite popular … and many of the voters of the center-right party were in favor of these welfare programs,” commented one of the researchers, Rune Slothuus. “Nevertheless, we can see that they reversed their opinion from supporting these welfare programs to opposing these welfare programs.”

“I was surprised to see the parties appeared this powerful in shaping opinions,” Slothuus said. “Our findings suggest that partisan leaders can indeed lead citizens’ opinions in the real world, even in situations where the stakes are real and the economic consequences tangible.”

The researchers pondered Western democracy in light of their findings: “If citizens just blindly follow their party without thinking much about it, that should lead to some concern about the mechanisms in our democracy. Because how can partisan elites represent citizens’ views if the views of citizens are shaped by the very same elites who are supposed to represent them?”

The brain listens for things it is trying to predict

The brain interprets sounds as they contrast with its expectations. It recognizes patterns of sounds faster when they’re in line with what it is predicting it will hear, but it only encodes sounds when they contrast with expectations, according to Technische U researchers.

Researchers showed this by monitoring the two principal nuclei of the subcortical pathway responsible for auditory processing: the inferior colliculus and the medial geniculate body, as their subjects listened to patterns of sounds which the researches modified so that sometimes they would hear an expected sound pattern, and other times something unexpected.

We have a particular way of understanding a room

When several research subjects were instructed to explore an empty room, and when they were instead seated in a chair and watched someone else explore the room, their brain waves followed a certain pattern, as recorded by a backpack hooked up to record their brain waves, eye movements, and paths. It didn’t matter if they were walking or watching someone else, according to UC researchers led by Dr Matthias Stangl.

The researchers also tested what happened when subjects searched for a hidden spot, or watched someone else do so, and found that brain waves flowed more strongly when they had a goal and hunted for something.

Extroverts and introverts use different vocabularies

Extroverts use ‘positive emotion’ and ‘social process’ words more often than introverts, according to new research conducted at Nanyang Technological U.

‘Love,’ ‘happy,’ and ‘blessed’ indicate pleasant emotions, and ‘beautiful’ and ‘nice’ indicate positivity or optimism, and are among the words found to be used more often by extroverts. So too are ‘meet,’ ‘share,’ and ‘talk,’ which are about socializing. Extroverts use personal pronouns — except ‘I’ — more too, another indication of sociability.

The correlation, however, was small, and the researchers think that stronger linguistic indicators need to be found to achieve their general goal, which is improving machine learning approaches to targeting consumer marketing.

WhatsApp is changing today - Users must give the app permission to send their private data to Facebook or lose account

WhatsApp was bought by Facebook in 2014, but has thrived while promoting itself as a privacy-respecting messaging app that now has 1.5b monthly active users. This week, though, WhatApp sent out an update to users’ phones that they must ‘consent’ to a new policy or lose access.

Whatsapp will now share more of your data, including your IP address (your location) and phone number, your account registration information, your transaction data, and service-related data, interactions on WhatsApp, and other data collected based on your consent, with Facebook’s other companies. Facebook has been working towards more closely integrating Facebook, WhatsApp, Instagram and Messenger.

Users who do not agree to ‘consent’ to the new policy will see their WhatsApp account become inaccessible until they do ‘consent.’ These accounts will remain dormant for 120 days after which they will be ‘deleted.’

The biggest change to the user policy, which many people ignored and clicked ‘agree’ to, thinking it was just another unimportant app update message, now reads,

‘We collect information about your activity on our Services, like service-related, diagnostic, and performance information. This includes information about your activity (including how you use our Services, your Services settings, how you interact with others using our Services (including when you interact with a business), and the time, frequency, and duration of your activities and interactions), log files, and diagnostic, crash, website, and performance logs and reports. This also includes information about when you registered to use our Services; the features you use like our messaging, calling, Status, groups (including group name, group picture, group description), payments or business features; profile photo, “about” information; whether you are online, when you last used our Services (your “last seen”); and when you last updated your “about” information.’

Notably, Elon Musk tweeted on the news, saying that WhatsApp users should switch to Signal, one of several popular privacy-focused messaging apps similar to WhatsApp.

New mathematical law found to beautifully explain crowd phenomena

New mathematical law found to beautifully explain crowd phenomena

A new law of science has been found to beautifully explain crowd movements for first time. The as-yet unnamed law, which is a mathematical, universal power law for human interactions, was found by U of M researchers who analyzed complex datasets that have only recently been available. The movement of crowds is fundamentally anticipatory in nature, according to the researchers, and the new, simple energy law expresses, in the words of its lead author, “the beauty of human nature.”

“The law we identified is brand new; such a law would have been impossible to identify 10 years ago as we simply did not have the technology to track pedestrian crowds at a large-scale,” Dr Ioannis Karamouzas, Research Associate at the University of Minnesota’s Department of Computer Science and Engineering and first author of the report, told The Speaker.

New law of science found to beautifully explain crowd phenomena
Dr Ioannis Karamouzas

“Nowadays, though, in the era of big-data there is a plethora of publicly available human crowd data. By analyzing such data, we found that, unlike particle-based interactions, the interactions between pedestrians are anticipatory in nature,” Karamouzas told us, referring to previous models that had attempted to predict crowd behavior with data based on repulsive particles rather than humans.

“To be more specific, when two particles interact the amount of energy that they have to expend to avoid colliding with each other depends on how close they are. In contrast, when two pedestrians interact, their energy depends on the ‘time-to-collision,’ i.e., the time that it takes for the pedestrians to collide assuming that they do not change course; as a collision becomes more imminent, this energy increases drastically.”

Karamouzas and his team have discovered a universal parameter based on single variable that explains crowd movement.

New mathematical law found to beautifully explain crowd phenomena“Surprisingly, the relationship between interaction energy and time-to-collision consistently follows a simple mathematical law stating that the degree to which two pedestrians are willing to respond to each other is inversely proportional to the square of their projected time-to-collision.”

Karamouzas elaborated on the types of crowd phenomena that could be explained by the new law.

“This law is broadly applicable as it consistently holds across different crowd settings; we analyzed both sparse and dense human crowds and found that pedestrian interactions follow the same power-law relationship. Our law has allowed us to gain a better understanding into how human behave and interact in a crowd.

“Looking into the future, I believe that such a law will have broad applications into our everyday life, from simulating in a more accurate way pedestrian behaviors in games, training simulators and animated movies, to designing safer buildings and pedestrian facilities.”

Karamouzas also explained how a law could so simply cover such range in speeds, densities and situations.

“That’s the beauty of the human nature! Every person in a crowd is certainly unique with his/her own desires and individual goals. What our law captures is how people adapt their courses in response to others around them. And such adaptations directly follow from the psychology of anticipation. As we move through a crowd our brain is able to process visual and acoustic cues and recognize the future consequences of our actions allowing us to react accordingly. And it’s the interaction between each person’s individual goals and our inferred law that allows pedestrians to exhibit such a large variety of behaviors.”

The law could not have been found in the past, due to the complexity required of the analysis.

“When we move in a crowd, we typically experience a complex system of competing forces,” said Karamouzas. “On one hand we have a goal that we are tying to reach–e.g. grocery store–and on other hand we try not to bump into other people. On top of that, we hardly ever walk alone but in small groups–such as couples, families, friends, etc. As such, we have to account for all these factors and continuously make our own decisions, which makes very hard to isolate/identify the primary rule that describes our interactions in a crowd. Much of the work in our paper was developing a new analysis technique which can account for the effect of all these forces simultaneously. Because the technique we employed was statistical in nature, we needed to analyze thousands of trajectories to robustly determine the pedestrian interaction law.”

Karamouzas went into detail about how his team found the law.

“We turned into a large collection of publicly available pedestrian datasets that are nowadays available thanks to the advances in automated tracking and computer vision,” said Karamouzas. “Overall, we analyzed six datasets New mathematical law found to beautifully explain crowd phenomenaconsisting of students walking in college campuses, pedestrians interacting at commercial streets, and a few controlled experiments where participants navigate through narrow bottlenecks.

Previously, there had been formidable challenges facing researchers who wanted to find an accurate and general rule for pedestrian behavior.

“To overcome the challenges that I mentioned already and robustly quantify the interaction law of pedestrians we employed a novel approach rooted in condensed matter physics. We initially measured the probability that any pair of pedestrians in the data has of maintaining a certain separation distance. We basically hypothesized that similar to charged particles, the interaction between pedestrians is distance-dependent. However, we found that the probability plots were very different for different walking speeds; when two pedestrians approach each other very fast they tend to maintain a larger separation distance than when they move slowly, as opposed to particles. As such, we started looking into different variables that can describe the interactions between pedestrians and we found that the time-to-collision is a sufficient descriptor. The probability plots were the same for different speeds as well as different orientations at which pedestrians approach each other. In addition, the time-to-collision measure naturally accounts for pedestrians coming relatively close to one another when moving in roughly the same direction–e.g. a pair of friends walking line-abreast. Eventually, by analyzing all the data, we inferred a simple energy law for the interactions between pairs of pedestrians.”

The research is considered to hold new promise for improved public architecture and spaces, the failings of which in the past have caused deaths.

“First of all, the nice thing about our newly identified law is that it directly implies an accurate model of simulating crowd flows. And through such simulations, we can design safer buildings as well as improve the efficiency of New mathematical law found to beautifully explain crowd phenomena (4)existing facilities–e.g., better egress times at a stadium. Furthermore, our novel way of analyzing crowd data and directly measuring the “interaction energy” between pairs of pedestrians opens interesting avenues for future work. For example, we would like to analyze crowd data from mass gatherings, such as concerts, and see how the interaction energy can be used to identify critical areas preventing the likelihood of crowd disasters–like the Love Parade in 2010).

Karamouzas commented on what he thought may be the most important thing for readers to understand of the research.

“The main take-away message is that a lot of the complexity of pedestrian interactions can be captured using simple mathematical equations. The universality of how pedestrian respond to each other is really surprising, and understanding this can lead to more accurate simulations, safer building designs, and shed some light into the anticipatory nature of human interactions.

The report, Universal Power Law Governing Pedestrian Interactions, was authored by Drs. Ioannis Karamouzas, Brian Skinner, and Stephen J. Guy, and was published in Physical Letters Reviews last week.

Material advantage: new metal matrix may cause marine engineers to switch

metal matrix

Metal sea wreckage might be made to float

The development of a new metal matrix composite foam may tip the balance back towards metal materials in the construction of marine vehicles — in addition to offering heat resistance well beyond that of the fiberglasses common in the industry today. According to NYU engineers, the first lighter-than-water metal construction foam can withstand significant pressure and three times as much heat as fiberglass.

“This is the first time anybody has been able to achieve density of the composite lower than that of water to create naturally buoyant materials,” explained New York University Polytechnic School of Engineering’s Dr. Nikhil Gupta.

The metal matrix composite is a magnesium alloy reinforced with spherical silicon carbide particles. The density — 0.92 grams per cubic centimeter versus water’s 1.0 – still allows the material to withstand 25,000 pounds per square inch of pressure before rupturing.

Some of the strength of the material is due to the hallow particles embedded in the material, which absorb energy during a fracture. With different measures of spheres added to the matrix, various densities can be created.

“The spheres are manufactured by our industrial partner Deep Spring Technology, Toledo, OH, USA,” noted Gupta, an expert in mechanical and aerospace engineering.

GUP_3482Spheres were the shape of choice for the foam. “This company also has capabilities of manufacturing hollow particles of many other shapes,” said Gupta, who referred to two other types of particle shapes — made of silicon carbide [gray color] and alumina [white color].

GUP_3486 - Copy“Spherical particles have advantage that their properties are the same from any side. Particles of different shapes need to be used with more caution with regard to loading them along their strongest direction.”

The light-weight heat-resistant material is also expected to offer potential improvements in fuel economy for land transportation. The ability of metallic materials to withstand high temperatures is one of the main selling points, Gupta noted.

“Some of the competing materials are polymer matrix composites, commonly known as ‘fiberglass.’ One of the limitations of fiberglass materials is that they cannot be used over 150 degrees Celsius because polymer will degrade or burn. In addition, fire, smoke, and toxicity are concerns when polymers are exposed to high temperature. Magnesium and Magnesium matrix composites can be used up to about 500 degrees Celsius. Automotive components such as pistons, connecting rods, exhaust systems and structural components can be made of lightweight Mg matrix composite materials. High temperature in many of these components prohibits use of polymer matrix composites.

“The Magnesium-hollow sphere composites that we have developed also absorb a large amount of energy under compression. This property is desirable in automotive energy absorber components in cursing zones. These foams can also be filled in A and B-pillars of cars, and doors for side impact energy absorption.”

The technology may be put into use in prototype automobiles and boats within three years, as well as in amphibious vehicles developed by the US military, where currently the trend is toward other materials, although experts consider that the new lightweight product may again give metals a material advantage.

“Weight reduction in transportation applications can help in reducing the fuel consumption,” Gupta told us. “In addition, the high energy absorption capability per unit mass in these materials can also help in making vehicles safer. However, one material cannot be used to make all components, we need to find the components that will benefit the most from these new materials.

Fragrances are a woman’s secret, even from her friends

fragrance

A recent study by Dutch design aesthetics researchers has discovered that women closely guard their fragrance identity to the point that they will keep it secret from the entire world if they can — so secret that even their friends cannot copy their personal scent, and they certainly won’t buy perfumes they like for their friends.

“The question here is not only: how do you express you identity? But it is: what types of items can someone else buy for you?” Dr. Rick Schifferstein of Delf University of Technology in the Netherlands told The Speaker. Schifferstein and his team were studying what effects packaging has on fragrance purchase when they made the somewhat unexpected discovery.

“Everyone expresses their identity through their appearance and their actions,” he explained. “Apparently, your identity  is not only expressed through the way you dress or your haircut, but also by the fragrance you wear.

Women won’t buy perfumes for each other, the team found, unless they don’t like the scent themselves, or when they may have previously liked the scent but no longer have a purpose for it. Actually, the researchers found, women tend to “sabotage” their friends when they give this type of gift. Women will buy a scent they like for themselves or their boyfriend — which is something women like to do, the findings showed — but will only buy scents they dislike for their female friends.

“While women hold fragrances as personally intimate and respect other women’s intimate choices, they happily want to influence what fragrances men wear,” Dr Bryan Howell, co-author of the study, said. “Assuming it is for a spouse or boyfriend, they want to pick fragrances they also like since they’ll be around that person often.”

The issue is more complicated than a simple concept of “sabotage” though, according to the researchers, and has to do with the importance of personal identity. Schifferstein explained some of the complexity of the issue by referring to the gift motivations, concerns and preferences of women.

“Giving someone a fragrance might suggest that they need one because they smell bad. This could cause unwanted questions to occur between friends. Women prefer to avoid that possibility and look for a gift that is safer to share.”

In case women do give their friends fragrances, it may concern fragrances that are no longer working for themselves and that are passed on to their friends, in hopes that they will work for them. Alternatively, women may appreciate the personality or preference differences between themselves and their friends, and may decide to give them a fragrance that has a different character than what they would buy for themselves.

“Fragrance categories — for example, fruity, spicy, citrus, floral — may play an important role in this process: Some women identified themselves as belonging to a certain category and they would consider purchasing only fragrances from this category for themselves. Consequently, they would not recommend these fragrances for their female best friends.”

The gifts women choose for each other tend to be purchased with a strong motivation to play it safe: “The more intimate the item, the less likely it will be considered appropriate as a gift.” Gifts such as CDs, books, and flowers tend to suit this less intimate, more safe approach, Schifferstein told us.

The report, “Using color–odor correspondences for fragrance packaging design” was completed by Bryan F. Howell and Hendrik N.J. Schifferstein, and was published on Science Direct.

When political parties reverse their policy stance, their supporters immediately switch their opinions too

At least a significant portion of their supporters, according to U of Aarhus researchers.

When two competing political parties in Denmark reversed their policy stance on an issue — suddenly they both supported reducing unemployment benefits — their voters immediately moved their opinions by around 15% into line with their party.

The same thing happened when one of these parties shifted from opposing to supporting ending Denmark’s early retirement.

The researchers were studying how public opinion is formed. Their recent paper sheds light on how much influence political parties have over their supporters, according to the researchers, who surveyed their panel of subjects in five successive waves between 2010 and 2011. They studied the same group of party supporters before, during and after a policy reversal.

“We can see that [the] welfare programs were actually quite popular … and many of the voters of the center-right party were in favor of these welfare programs,” commented one of the researchers, Rune Slothuus. “Nevertheless, we can see that they reversed their opinion from supporting these welfare programs to opposing these welfare programs.”

“I was surprised to see the parties appeared this powerful in shaping opinions,” Slothuus said. “Our findings suggest that partisan leaders can indeed lead citizens’ opinions in the real world, even in situations where the stakes are real and the economic consequences tangible.”

The researchers pondered Western democracy in light of their findings: “If citizens just blindly follow their party without thinking much about it, that should lead to some concern about the mechanisms in our democracy. Because how can partisan elites represent citizens’ views if the views of citizens are shaped by the very same elites who are supposed to represent them?”

The brain listens for things it is trying to predict

The brain interprets sounds as they contrast with its expectations. It recognizes patterns of sounds faster when they’re in line with what it is predicting it will hear, but it only encodes sounds when they contrast with expectations, according to Technische U researchers.

Researchers showed this by monitoring the two principal nuclei of the subcortical pathway responsible for auditory processing: the inferior colliculus and the medial geniculate body, as their subjects listened to patterns of sounds which the researches modified so that sometimes they would hear an expected sound pattern, and other times something unexpected.

We have a particular way of understanding a room

When several research subjects were instructed to explore an empty room, and when they were instead seated in a chair and watched someone else explore the room, their brain waves followed a certain pattern, as recorded by a backpack hooked up to record their brain waves, eye movements, and paths. It didn’t matter if they were walking or watching someone else, according to UC researchers led by Dr Matthias Stangl.

The researchers also tested what happened when subjects searched for a hidden spot, or watched someone else do so, and found that brain waves flowed more strongly when they had a goal and hunted for something.

Extroverts and introverts use different vocabularies

Extroverts use ‘positive emotion’ and ‘social process’ words more often than introverts, according to new research conducted at Nanyang Technological U.

‘Love,’ ‘happy,’ and ‘blessed’ indicate pleasant emotions, and ‘beautiful’ and ‘nice’ indicate positivity or optimism, and are among the words found to be used more often by extroverts. So too are ‘meet,’ ‘share,’ and ‘talk,’ which are about socializing. Extroverts use personal pronouns — except ‘I’ — more too, another indication of sociability.

The correlation, however, was small, and the researchers think that stronger linguistic indicators need to be found to achieve their general goal, which is improving machine learning approaches to targeting consumer marketing.

WhatsApp is changing today - Users must give the app permission to send their private data to Facebook or lose account

WhatsApp was bought by Facebook in 2014, but has thrived while promoting itself as a privacy-respecting messaging app that now has 1.5b monthly active users. This week, though, WhatApp sent out an update to users’ phones that they must ‘consent’ to a new policy or lose access.

Whatsapp will now share more of your data, including your IP address (your location) and phone number, your account registration information, your transaction data, and service-related data, interactions on WhatsApp, and other data collected based on your consent, with Facebook’s other companies. Facebook has been working towards more closely integrating Facebook, WhatsApp, Instagram and Messenger.

Users who do not agree to ‘consent’ to the new policy will see their WhatsApp account become inaccessible until they do ‘consent.’ These accounts will remain dormant for 120 days after which they will be ‘deleted.’

The biggest change to the user policy, which many people ignored and clicked ‘agree’ to, thinking it was just another unimportant app update message, now reads,

‘We collect information about your activity on our Services, like service-related, diagnostic, and performance information. This includes information about your activity (including how you use our Services, your Services settings, how you interact with others using our Services (including when you interact with a business), and the time, frequency, and duration of your activities and interactions), log files, and diagnostic, crash, website, and performance logs and reports. This also includes information about when you registered to use our Services; the features you use like our messaging, calling, Status, groups (including group name, group picture, group description), payments or business features; profile photo, “about” information; whether you are online, when you last used our Services (your “last seen”); and when you last updated your “about” information.’

Notably, Elon Musk tweeted on the news, saying that WhatsApp users should switch to Signal, one of several popular privacy-focused messaging apps similar to WhatsApp.

The data sharing policy change doesn’t affect people in Europe due to GDPR data protection regulations.

Wikipedia Vulnerabilities Explored In New Research

Monopolization of community-based information networks by cartels of a few “super editors” among several risks that could lead to a diminished Wikipedia

Wikipedia’s quality benefits from high levels of free participation, but volunteer information databases like Wikipedia can be negatively effected by tendencies toward information monopolization, and, according to a recent study, this negative effect is more prevalent in more frequently edited articles — articles that could be considered to be more important.

In the study, researchers at the Korea Advanced Institute of Science and Technology and the Korea Institute for Advanced Study looked at how editors interact with each other as well as how they interact with articles, and integrated previously-ignored factors such as the consideration of real time — not just the number of edits used in previous studies to mark time.

Among the team’s findings: infrequently-referred articles grow faster than frequently-referred ones. Not only that, but articles that attracted a high motivation to edit actually reduced the number of participants. Yun and his colleagues inferred that this type of Wikipedia article participation decay results in inequality among community editors. The trend will become more severe as time goes on, they suspected:

“For the previous decade, many of these open-editing access movements have significantly affected the entire

Jinhyuk Yun

society,” Jinhyuk Yun, a Ph.D. candidate at the Complex Systems and Statistical Physics Lab at the Korea Advanced Institute of Science and Technology in Daejeon, South Korea, told us.

“Wikipedia, Creative Commons Licenses, GNU, etc. To sustain such movements, they must maintain their motivations for participants, which might be taken away by monopolization.”

Yun explained how communal information databases like Wikipedia slow down.

“There are various reasons to participate in such ‘open-editing’ movements. Some are collective reasons shared in a society, and others are somewhat personal. Because the motivation is diverse, slowing down is also due to various causes. First, there can be a loss of necessity to contribute due to changes in society — or technology. Some GNU software based on old platforms no longer continue because the number of users of such software is getting smaller. In addition, there can be new barriers caused by governmental regulations — not about such communal databases, but considering the case of UBER. One particular candidate we discussed in the paper is the monopolization by few ‘super-editors.'”

Yun also commented on how we can consider the health of such community databases?

“It is very hard to quantify the ‘health’ of such database because of the ambiguity in the definition of health. In my point of view, the databases should meet the standard of accuracy and instantaneity. In other words, it should keep the trend, but it should not lose its accuracy in the contents. Although these databases are mainly based on the contribution of anonymous sources, it should also have reliable references to cross-check.”

However, data monopolization is not a black and white issue, Yun noted.

“To be honest, monopolization sometimes does good in particular occasions,” Yun told us, “yet it has many risks in most cases. Consider political issues in authoritarian governments, where media controlled by the government sometimes manipulates people’s opinions by a simple nudge or filtering. Such manipulation can also happen in Wikipedia — for example, by cartels of super-editors.”

Yun offered some possible remedies for content monopolization on Wikipedia:

“Based on our observations, Wikipedia could consider a reward program to recruit new editors. Simple achievement reward programs — like those in video games — at an early stage might be helpful, yet it should be done under strict supervision to avoid vandals. For instance, giving merit to editors who supply new reliable references might help to keep the quality of articles.”

The report, “Intellectual interchanges in the history of massive online open-editing encyclopedia, Wikipedia” was completed by J. Yun, S. H. Lee, and H. Jeong.

Back to the Moon? Trump’s Statement Rouses Spaceheads

moon mission

When President Donald Trump mentioned “other worlds” in his speech to a join Congress this week, the space community started buzzing.

“American footprints on distant worlds are not too big a dream,” said Trump at the end of his speech.

According to PBS NewsHour Science Correspondent Miles O’brian a manned mission could take place in 2019, as “all of a sudden there is wide agreement in the space community [the moon] might be the next step.” The mission may take the form of “learning how to live there on a sustained basis” — ie, a manned encampment.

A traditional barrier to space missions has been the large cost. NASA’s budget is around 19 billion, and the Army’s budget for space is around $40 billion, and analysts are considering ways these two organizations could borrow from each other in a force multiplier relationship, making it possible to make a moon mission with reduced costs to the country.

The private sector is also increasingly interested in the moon. SpaceX also is continuing to push toward commercial voyages. Elon Musk’s company announced a tourist trip for two people around the moon before.

Dubai to Have Flying Driverless Cars This Summer

Dubai to Have Flying Driverless Cars This Summer

In a few months, the UAE will have flying driverless cars, according to Dubai’s transport authority.

They’ve already done test runs for the autonomous aerial vehicles (AAV), made by Chinese firm Ehang.

The vehicles are Ehang 184s and can carry one pilot.

Top speed: 160kph
Flight time: 30 minutes
Ascending speed: 8 meters / second
Landing speed: 4 meters / second
Weight:250kg empty / 360kg with passenger
Max cruising height:3000 feet
Charging time:1-2 hours

“The AAV exhibited at the summit is not just a model; it is a real version that we have already experimented the vehicle in a flight in Dubai sky. The RTA is making every effort to start the operation of the AAV in July 2017,” said Mattar Al Tayer, the director general and chairman of the RTA.

Video of the Ehang 184 test

The RTA, in collaboration with the Chinese firm Ehang, has carried out the first test run of an autonomous aerial vehicle (AAV) capable of carrying a human, the Ehang 184, and the authority said it is set to launch operations very soon.

The flying car was exhibited at the World Government Summit in Dubai this week and the chief of the RTA said a summer start date for flights is envisioned.

“The AAV exhibited at the summit is not just a model; it is a real version that we have already experimented the vehicle in a flight in Dubai sky. The RTA is making every effort to start the operation of the AAV in July 2017,” said Mattar Al Tayer, the director general and chairman of the RTA.

The Ehang 184 is fitted with a touchscreen to the front of the passenger seat displaying a map of all destinations in the form of dots. It has preset routes and the passenger selects the intended destination. The vehicle will then start automatic operation, take off and cruise to the set destination before descending and landing in a specific spot. A ground-based centre will monitor and control the entire operation.

“The trial run of the first AAV is in implementation of the directives of Sheikh Mohammed bin Rashid Al Maktoum, Vice-President and Prime Minister of the UAE and Ruler of Dubai, to transform Dubai into the smartest city in the world,” said Mr Al Tayer

“It is also part of the RTA’s endeavors to provide self-driving transport through engaging in the technological tests of self-driving vehicles in a Dubai environment.

“It replicates Dubai Self-driving Transport Strategy aimed at transforming 25 per cent of total individual trips in Dubai into self-driving trips using various modes of transport by 2030,” added Mr Al Tayer.

“The step would also enhance the integration between public transport modes and people happiness through the provision of smooth, quick and innovative mobility.

“We have addressed the highest levels of security in the designing and manufacturing of the Ehang184. The vehicle is fitted with eight main propellers,” Mr Al Tayer said.

“In case of any failure in the first propeller, there would be seven other propellers ready to complete the flight and a smooth landing, while mitigating the impact of the fault sustained by the first propeller.”

Importantly, the vehicle has numerous basic systems all running independently, but at the same time, so that if something malfunctions a standby can take over.

“The AAV is designed to operate under all climatic conditions unless there is a thunderstorm. The vehicle is fitted with highly accurate sensors with a very low-error threshold and can resist vibrations and extreme temperatures,” said Mr Al Tayer.

“Dubai Civil Aviation Authority was a partner in our trials defining the safety criteria required, issuing the permits for trial and inspecting the vehicle, RTA appreciates their contribution.

“The 4G data network is used in communication between the AAV and the ground control center. The company had also provided the support needed to ensure the continued communication between the AAV and the control centre through M2M and LTE technologies,” he explained.

When several research subjects were instructed to explore an empty room, and when they were instead seated in a chair and watched someone else explore the room, their brain waves followed a certain pattern, as recorded by a backpack hooked up to record their brain waves, eye movements, and paths. It didn’t matter if they were walking or watching someone else, according to UC researchers led by Dr Matthias Stangl.

The researchers also tested what happened when subjects searched for a hidden spot, or watched someone else do so, and found that brain waves flowed more strongly when they had a goal and hunted for something.

Extroverts and introverts use different vocabularies

Extroverts use ‘positive emotion’ and ‘social process’ words more often than introverts, according to new research conducted at Nanyang Technological U.

‘Love,’ ‘happy,’ and ‘blessed’ indicate pleasant emotions, and ‘beautiful’ and ‘nice’ indicate positivity or optimism, and are among the words found to be used more often by extroverts. So too are ‘meet,’ ‘share,’ and ‘talk,’ which are about socializing. Extroverts use personal pronouns — except ‘I’ — more too, another indication of sociability.

The correlation, however, was small, and the researchers think that stronger linguistic indicators need to be found to achieve their general goal, which is improving machine learning approaches to targeting consumer marketing.

WhatsApp is changing today - Users must give the app permission to send their private data to Facebook or lose account

WhatsApp was bought by Facebook in 2014, but has thrived while promoting itself as a privacy-respecting messaging app that now has 1.5b monthly active users. This week, though, WhatApp sent out an update to users’ phones that they must ‘consent’ to a new policy or lose access.

Whatsapp will now share more of your data, including your IP address (your location) and phone number, your account registration information, your transaction data, and service-related data, interactions on WhatsApp, and other data collected based on your consent, with Facebook’s other companies. Facebook has been working towards more closely integrating Facebook, WhatsApp, Instagram and Messenger.

Users who do not agree to ‘consent’ to the new policy will see their WhatsApp account become inaccessible until they do ‘consent.’ These accounts will remain dormant for 120 days after which they will be ‘deleted.’

The biggest change to the user policy, which many people ignored and clicked ‘agree’ to, thinking it was just another unimportant app update message, now reads,

‘We collect information about your activity on our Services, like service-related, diagnostic, and performance information. This includes information about your activity (including how you use our Services, your Services settings, how you interact with others using our Services (including when you interact with a business), and the time, frequency, and duration of your activities and interactions), log files, and diagnostic, crash, website, and performance logs and reports. This also includes information about when you registered to use our Services; the features you use like our messaging, calling, Status, groups (including group name, group picture, group description), payments or business features; profile photo, “about” information; whether you are online, when you last used our Services (your “last seen”); and when you last updated your “about” information.’

Notably, Elon Musk tweeted on the news, saying that WhatsApp users should switch to Signal, one of several popular privacy-focused messaging apps similar to WhatsApp.

The data sharing policy change doesn’t affect people in Europe due to GDPR data protection regulations.

3D Printing Against Daesh: “We Will Recreate What ISIS Destroyed”

3D technology comes to the rescue after the destruction of several world cultural treasures by the militant group Islamic State in Iraq and Syria (ISIS).

According to the United Nations, ISIS has destroyed and damaged 200 world heritage sites along with hundreds of statues and artefacts since 2014.

ISIS’ plan is simple. It is about erasing all traces of previous cultures to establish their own and take advantage of the media coverage following massing destructions of historic sites to grab the world’s attention. In addition, this cultural cleaning is a way for Daesh to finance their activities by selling to dealers and private collectors.

Yet those lost treasures that some call “blood artifacts” may not be lost forever.

Through her digital fabrication and 3D printing project “Material Speculation : ISIS”, Iranian artist and activist Morehshin Allahyari chose to focus on the reconstruction of selected artifacts and statues destroyed by ISIS in Iraq in 2015.

In addition, to repair history and memory, each 3D printed object comprises a flash drive and a memory card. The data in these flash drives contain materials: maps, images, videos and pdf files on the destroyed artifacts and sites. They were gathered thanks to a collaboration with different archaeologists and historians, including and museum staff.

“Like time capsules, each object is sealed and kept for future civilizations.”
Morehshin Allahyari

Just like Murehshin Allahyari artifacts, Palmyra has suffered numerous act of vandalism. The Syrian desert city known as the Venice of the Sands lost the triumphal arch from 2,000-year-old Temple of Bel.

Devastated, many archaeologists talked restoration and reconstruction such as American lawyer/archaeologist Roger Michel. Indeed, as the founder of Oxford’s Institute for Digital Archaeology, Michel has built a 3D facsimile arch from Palmyra’s destroyed Temple of Bel.

Thanks to 3D technology, Palmyra’s rose again in London’s Trafalgar Square last April to coincide with world heritage week. It should then travel on to Times Square in New York City.

This 3D replica of the 15-meters arch that formed the temple’s entrance is a gesture of defiance against ISIS’ desire to erase cultural and historical evidence.

“My intention is to show Islamic State that anything they can blow up we can rebuild exactly as it was before, and rebuild it again and again. We will use technology to disempower ISIS.” Roger Michel

Moving for some or uncanny for others, this incredible public display of 3D reconstruction is the proof that new technology can restore entire parts of 20th-century historical sites. Although out of their original context and site, 3D monuments or artifacts might still conserve their precious sense of place and craftsmanship, thus preserving everybody’s heritage.

To prevent destruction caused by conflict, looting or natural disasters, they send teams on the ground to train people and help them document this heritage.

When political parties reverse their policy stance, their supporters immediately switch their opinions too

At least a significant portion of their supporters, according to U of Aarhus researchers.

When two competing political parties in Denmark reversed their policy stance on an issue — suddenly they both supported reducing unemployment benefits — their voters immediately moved their opinions by around 15% into line with their party.

The same thing happened when one of these parties shifted from opposing to supporting ending Denmark’s early retirement.

The researchers were studying how public opinion is formed. Their recent paper sheds light on how much influence political parties have over their supporters, according to the researchers, who surveyed their panel of subjects in five successive waves between 2010 and 2011. They studied the same group of party supporters before, during and after a policy reversal.

“We can see that [the] welfare programs were actually quite popular … and many of the voters of the center-right party were in favor of these welfare programs,” commented one of the researchers, Rune Slothuus. “Nevertheless, we can see that they reversed their opinion from supporting these welfare programs to opposing these welfare programs.”

“I was surprised to see the parties appeared this powerful in shaping opinions,” Slothuus said. “Our findings suggest that partisan leaders can indeed lead citizens’ opinions in the real world, even in situations where the stakes are real and the economic consequences tangible.”

The researchers pondered Western democracy in light of their findings: “If citizens just blindly follow their party without thinking much about it, that should lead to some concern about the mechanisms in our democracy. Because how can partisan elites represent citizens’ views if the views of citizens are shaped by the very same elites who are supposed to represent them?”

The brain listens for things it is trying to predict

The brain interprets sounds as they contrast with its expectations. It recognizes patterns of sounds faster when they’re in line with what it is predicting it will hear, but it only encodes sounds when they contrast with expectations, according to Technische U researchers.

Researchers showed this by monitoring the two principal nuclei of the subcortical pathway responsible for auditory processing: the inferior colliculus and the medial geniculate body, as their subjects listened to patterns of sounds which the researches modified so that sometimes they would hear an expected sound pattern, and other times something unexpected.
