Social networking's good and bad impacts on kids | KurzweilAI - 0 views

  •  
    Social media present risks and benefits to children but parents who try to secretly monitor their kids' activities online are wasting their time, says Larry D. Rosen, Ph.D., professor of psychology at California State University, Dominguez Hills. Rosen identifies potential adverse effects of social media, including: Teens who use Facebook more often show more narcissistic tendencies, while young adults who have a strong Facebook presence show more signs of other psychological disorders, including antisocial behaviors, mania, and aggressive tendencies. Daily overuse of media and technology has a negative effect on the health of all children, especially preteens and teenagers, by making them more prone to anxiety, depression, and other psychological disorders, and making them more susceptible to future health problems. Facebook can be distracting and can negatively impact learning. Studies found that middle school, high school and college students who checked Facebook at least once during a 15-minute study period achieved lower grades. Rosen says new research has also found positive influences linked to social networking, including: Young adults who spend more time on Facebook are better at showing "virtual empathy" to their online friends. Online social networking can help introverted adolescents learn how to socialize. Social networking can provide tools for teaching in compelling ways that engage young students. "If you feel that you have to use some sort of computer program to surreptitiously monitor your child's social networking, you are wasting your time. Your child will find a workaround in a matter of minutes," he says. "You have to start talking about appropriate technology use early and often and build trust, so that when there is a problem, whether it is being bullied or seeing a disturbing image, your child will talk to you about it."

People who really identify with their car drive more aggressively, study finds - 0 views

  •  
    The studies found:People who perceive their car as a reflection of their self-identity are more likely to behave aggressively on the road and break the law.People with compulsive tendencies are more likely to drive aggressively with disregard for potential consequences.Increased materialism, or the importance of one's possessions, is linked to increased aggressive driving tendencies.Young people who are in the early stages of forming their self-identity might feel the need to show off their car and driving skills more than others. They may also be overconfident and underestimate the risks involved in reckless driving.Those who admit to aggressive driving also admit to engaging in more incidents of breaking the law.A sense of being under time and pressure leads to more aggressive driving.

US approves world's biggest solar energy project in California | KurzweilAI - 0 views

  •  
    The U.S. Department of Interior approved on Monday a permit for Solar Millennium, LLC to build the largest solar energy project in the world - four  plants at the cost of one billion dollars each - in southern California. The project is expected to generate up to 1,000 Megawatts of energy, enough electricity to annually power more than 300,000 single-family homes, more than doubling the solar electricity production capacity of the U.S. Once constructed, the Blythe facility will reduce CO2 emissions by nearly one million short tons per year, or the equivalent of removing more than 145,000 cars from the road. Additionally, because the facility is "dry-cooled," it will use 90 percent less water than a traditional "wet-cooled" solar facility of this size. The Blythe facility will also help California take a major step toward achieving its goal of having one third of the state's power come from renewable sources by the year 2020. The entire Blythe Solar Power Project will generate a total of more than 7,500 jobs, including 1,000 direct jobs during the construction period, and thousands of additional indirect jobs in the community and throughout the supply chain. When the 1,000 MW facility is fully operational it will create more than 220 permanent jobs. Adapted from materials provided by Solar Millennium, LLC.

Citizen Scientist 2.0 - 1 views

  •  
    What does the future of science look like? About a year ago, I was asked this question. My response then was: Transdisciplinary collaboration. Researchers from a variety of domains-biology, philosophy, psychology, neuroscience, economics, law-all coming together, using inputs from each specialized area to generate the best comprehensive solutions to society's more persistent problems. Indeed, it appears as if I was on the right track, as more and more academic research departments, as well as industries, are seeing the value in this type of partnership. Now let's take this a step further. Not only do I think we will be relying on inputs from researchers and experts from multiple domains to solve scientific problems, but I see society itself getting involved on a much more significant level as well. And I don't just mean science awareness. I'm talking about actually participating in the research itself. Essentially, I see a huge boom in the future for Citizen Science.

    When we talk about participation, we have to be a bit more specific. On the publishing side, there's clearly more participation than we've ever seen in the past. But in order for this tidal wave of information to be useful, we need to be able to separate fact from fiction. We need to encourage participation on the receiving end. What we need is evaluating participation. With the breadth of niche information and sources we have the ability to get at the best of what is known on a myriad of topics and contexts. Every niche has its experts and its hacks, its enthusiasts and detractors. But for the remaining 95% of us who are not subject matter experts, deriving the accurate or useful information from the sea of what is available can be complicated, time-consuming and simply unverifiable. We need a way to quantify the value of information, or more specifically, the veracity of information.

5 Things That Internet Porn Reveals About Our Brains | Sex & the Brain | DISCOVER Magazine - 0 views

  •  
    With its expansive range and unprecedented potential for anonymity, (the Internet gives voice to our deepest urges and most uninhibited thoughts. Inspired by the wealth of unfettered expression available online, neuroscientists Ogi Ogas and Sai Gaddam, who met as Ph.D. candidates at Boston University, began plumbing a few chosen search engines (including Dogpile and AOL) to create the world's largest experiment in sexuality in 2009. Quietly tapping into a billion Web searches, they explored the private activities of more than 100 million men and women around the world. The result is the first large-scale scientific examination of human sexuality in more than half a century, since biologist Alfred Kinsey famously interviewed more than 18,000 middle-class Caucasians about their sexual behavior and published the Kinsey reports in 1948 and 1953. Building on the work of Kinsey, neuroscientists have long made the case that male and female sexuality exist on different planes. But like Kinsey himself, they have been hampered by the dubious reliability of self-reports of sexual behavior and preferences as well as by small sample sizes. That is where the Internet comes in. By accessing raw data from Web searches and employing the help of Alexa-a company that measures Web traffic and publishes a list of the million most popular sites in the world-Ogas and Gaddam shine a light on hidden desire, a quirky realm of lust, fetish, and kink that, like the far side of the moon, has barely been glimpsed. Here is a sampling of their fascinating results, selected from their book, A Billion Wicked Thoughts.

Hello, Darkness - 96.03 - 0 views

  • But the implication of electricity in the sleep deficit seems hard to argue with. Whatever it is that we wish or are made to do--pursue leisure, earn a living--there are simply far more usable hours now in which to do it
  • In the United States at midnight more than five million people are at work at full-time jobs. Supermarkets, gas stations, copy shops--many of these never close.
  • Living with electric lights makes it difficult to retrieve the experience of a non-electrified society. For all but the very wealthy, who could afford exorbitant arrays of expensive artificial lights, nightfall brought the works of daytime to a definitive end. Activities that need good light--where sharp tools are wielded or sharply defined boundaries maintained; purposeful activities designed to achieve specific goals; in short, that which we call work--all this subsided in the dim light of evening. Absent the press of work, people typically took themselves safely to home and were left with time in the evening for less urgent and more sensual matters: storytelling, sex, prayer, sleep, dreaming.

(The essay will appear in a book called The Idea of Progress Revisited, edited by Leo Marx and Bruce Mazlish.) Staudenmaier makes the point--obvious when brought up, though we've mostly lost sight of it--that from the time of the hominid Lucy, in Hadar, Ethiopia, to the time of Thomas Edison, in West Orange, New Jersey, the onset of darkness sharply curtailed most kinds of activity for most of our ancestors.

    Birth: it's a miracle. A rite of passage. A natural part of life. But more than anything, birth is a business. Compelled to find answers after a disappointing birth experience with her first child, actress Ricki Lake recruits filmmaker Abby Epstein to examine and question the way American women have babies. The film interlaces intimate birth stories with surprising historical, political and scientific insights and shocking statistics about the current maternity care system. When director Epstein discovers she is pregnant during the making of the film, the journey becomes even more personal. Should most births be viewed as a natural life process, or should every delivery be treated as a potentially catastrophic medical emergency?

A Philosophical Orientation Toward Solving Our Collective Problems As a Species | Think... - 0 views

  •  
    To know what the most important virtue of our age is we need to have at least a basic understanding of our age. Our era is becoming increasingly characterized by uncertainty. Fortunately or unfortunately, more than a cursory elucidation of our situation is beyond the scope of this essay. There are geopolitical, economic, technological and environmental trends worth mentioning. When the more philosophical portion of this  discourse arrives I will argue that the virtue of wisdom underlies the meaningfulness and efficacy of all other virtues, and this in broad strokes is primarily due to (1) the aforementioned instability in our surroundings ; (2) the relationship between the deontological and virtue; and (3) the nature of agency itself.  Whether uncertainty itself can provide an ethical foundation for us to elaborate on will be a separate question, and finally I speculate on where wisdom leads us in the context of a philosophy that is politically active and not doomed to irrelevance to and by the larger population.

Quantum mechanics can offer a secure way of communicating - 0 views

    There are differences between the group's demonstrations. For crystals, Tittel's group used thulium-doped lithium niobate, whereas Gisin's group opted for neodymium-doped yttrium silicate. In addition, a different type of laser set-up has favoured Gisin's group, which reports a maximum storage time of some 200 ns at an efficiency of more than 20%; Tittel's group reports a storage time of 7 ns at an efficiency of 2%. On the other hand, the quantum memory of Tittel's group functions at a bandwidth of 5 GHz - some 40 times greater than Gisin's group - which means, potentially, far more information could be sent in the same time.

The American Wikileaks Hacker | Rolling Stone Culture - 0 views

    On July 29th, returning from a trip to Europe, Jacob Appelbaum, a lanky, unassuming 27-year-old wearing a black T-shirt with the slogan "Be the trouble you want to see in the world," was detained at customs by a posse of federal agents. In an interrogation room at Newark Liberty airport, he was grilled about his role in Wikileaks, the whistle-blower group that has exposed the government's most closely guarded intelligence reports about the war in Afghanistan. The agents photocopied his receipts, seized three of his cellphones - he owns more than a dozen - and confiscated his computer. They informed him that he was under government surveillance. They questioned him about the trove of 91,000 classified military documents that Wikileaks had released the week before, a leak that Vietnam-era activist Daniel Ellsberg called "the largest unauthorized disclosure since the Pentagon Papers." They demanded to know where Julian Assange, the founder of Wikileaks, was hiding. They pressed him on his opinions about the wars in Afghanistan and Iraq. Appelbaum refused to answer. Finally, after three hours, he was released. Sex, Drugs, and the Biggest Cybercrime of All Time Appelbaum is the only known American member of Wikileaks and the leading evangelist for the software program that helped make the leak possible. In a sense, he's a bizarro version of Mark Zuckerberg: If Facebook's ambition is to "make the world more open and connected," Appelbaum has dedicated his life to fighting for anonymity and privacy. An anarchist street kid raised by a heroin- addict father, he dropped out of high school, taught himself the intricacies of code and developed a healthy paranoia along the way. "I don't want to live in a world where everyone is watched all the time," he says. "I want to be left alone as much as possible. I don't want a data trail to tell a story that isn't true." We have transferred our most intimate and personal information - our bank accounts, e-mails, photographs, ph

New Scientist TV: Become a virtual film-maker - 0 views

    Motion controllers used in gaming systems like the Nintendo Wii revolutionised how video games are played. But now a similar device that's more precise - and even works when an object is in its way - will let you try something more futuristic: making movies in virtual environments. Matt Bett and his team from Abertay University in the UK developed the new motion controller that uses electromagnetic sensors to track its 3D position. The location is then mapped in real time to a virtual video camera on a screen (see video above). By moving the controller around, the camera moves around the scene like a real camera on a rig or it can be fixed to a virtual tripod.

The Technium: Chosen, Inevitable, and Contingent - 0 views

  • There are two senses of "inevitable" when used with technology. In the first case, an invention merely has to exist once. In that sense, every technology is inevitable because sooner or later some mad tinkerer will cobble together almost anything that can be cobbled together. Jetpacks, underwater homes, glow-in-the-dark cats, forgetting pills — in the goodness of time every invention will inevitably be conjured up as a prototype or demo. And since simultaneous invention is the rule not the exception, any invention that can be invented will be invented more than once. But few will be widely adopted. Most won't work very well. Or more commonly they will work but be unwanted. So in this trivial sense, all technology is inevitable. Rewind the tape of time and it will be re-invented. The second more substantial sense of "inevitable" demands a level of common acceptance and viability. A technology's use must come to dominate the technium or at least its corner of the technosphere. But more than ubiquity, the inevitable must contain a large-scale momentum, and proceed on its own determination beyond the free choices of several billion humans. It can't be diverted by mere social whims.

    Anonymous uses its skills to extract user information from darknet websites specializing in child pornography. Tuesday, after hacking into Lolita City, a darknet website used by pedophiles to trade in child pornography, Anonymous released usernames and other information of 1,589 pedophiles trading in kiddie porn. The move comes after the group managed to take down more than 40 pedophile websites last week which were swapping images through the Tor anonymization network. A darknet website is a closed private network of computers used for file sharing. Darknet websites are part of the Invisible Web, sometimes called the Deep Web, containing content that is not part of the Surface Web, which is indexed by standard search engines. Yesterday Pastebin release, Anonymous enthusiasts explain the technical side of how they were able to locate and identify Lolita City and access their user data base. In a prior Pastebin release, Anonymous offers a timeline of events detailing the discovery of the hidden cache of more than 100 gigabytes of child porn associated with Lolita City.
