World on Wi-Fire by Nial Ferguson



World on Wi-Fire

Feel the chaos? Technology is feeding mind-boggling volatility everywhere.


Niall FergusonThe human race is interconnected as never before. Is that a good thing? Ask the Lords of the Internet—the men running the companies Eric Schmidt of Google recently called “the Four Horsemen”: Amazon, Apple, Facebook, and Google—and you’ll get an unequivocal “yes.” But is it true? In view of the extraordinary economic and political instability of recent months, it’s worth asking if the Netlords are the Four Horsemen of a new kind of information apocalypse.
Don’t get me wrong. I love all that these companies have achieved. I order practically everything except haircuts from Amazon. I write this column on a MacBook Pro. I communicate with my kids via Facebook. It’s 6:55 a.m., and I’ve already run six searches on Google. Did I forget to mention that I’ve already received 29 emails and sent 14?
I also really like the Netlords. They are among the smartest guys on the planet. Yet they are also self-deprecating and sometimes very funny. (OK, not Steve Jobs.) So my question for them is a real question, not some kind of Luddite rant: does the incredible network you have created, with its unprecedented scale and speed, not contain a vulnerability? I’m not talking here about the danger of its exploitation by Islamist extremists or its incapacitation by Chinese cyberwarriors, though I worry about those things too. No, I mean the possibility that the global computer network formed by technologically unified human minds is inherently unstable—and that it is ushering in an era of intolerable volatility.
The communications revolution we are living through has been driven by two great forces. One is Gordon E. Moore’s “law” (which he first proposed in 1965) that the number of transistors that can be placed inexpensively on an integrated circuit doubles approximately every 18 months. In its simplified form, Moore’s Law says that computing power will double every two years, implying a roughly 30-fold increase in 10 years. This exponential trend has now continued for more than half a century and is expected by the techies to continue until at least 2015 or 2020.
The other force is the exponential growth of human networks. The first email was sent at the Massachusetts Institute of Technology in the same year Moore’s Law was born. In 2006 people sent 50 billion emails; last year it was 300 billion. The Internet was born in 1982. As recently as 1993 only 1 percent of two-way telecommunication went through it. By 2000 it was 51 percent. Now it’s 97 percent. Facebook was dreamed up by an über-nerd at my university in 2004. It has 800 million active users today—eight times the number of three years ago.

Russian venture capitalist Yuri Milner sees this trend as our friend (it has certainly been his). As the number of people online doubles from 2 billion to 4 billion over the next 10 years and the number of Internet-linked devices quadruples from 5 billion to 20 billion, mankind collectively gets more knowledge—and gets smarter. Speaking at a conference in Ukraine in mid-September, Milner asserted that data equivalent to the total volume of information created from the beginning of human civilization until 2003 can now be generated in the space of just two days. To cope with this information overload, he looks forward to “the emergence of the global brain, which consists of all the humans connected to each other and to the machine and interacting in a very unique and profound way, creating an intelligence that does not belong to any single human being or computer.”
In the future as imagined by Google, this global brain will do much of our thinking for us, telling us (through our handheld devices) which of our friends is just around the next corner and where we can buy that new suit we need for the best price. And if the best price is on Amazon, we’ll just click once and look forward to its next-day delivery. Maybe it’ll already be there when we get home.
That’s the kind of sci-fi scenario that gets a true nerd out of bed in the morning. But is it just a bit too utopian?
Computer networks combine and amplify the primeval emotions of fear, love, and hate.
Exhibit one for a contrarian view is the recent behavior of global financial markets, the area of human activity furthest down the road of computerization and automation. According to math wonk Kevin Slavin, algorithms with names like the “Boston Shuffler” are the new masters of the financial universe. Whole tower blocks have been hollowed out to accommodate the computing power required by high-frequency (and very high-speed) trading. So how is this brave new world of robot traders doing?
Well, the VIX index of volatility—Wall Street’s so-called fear gauge, which infers the expected volatility of the U.S. stock market from options prices—reached an all-time high of 80 in the aftermath of Lehman Brothers’ failure and surged back up above 30 in early 2010 and again this summer. Part of this is just a good old-fashioned, man-made financial crisis, of course. But some of the volatility we’ve seen in the past four years is surely attributable to technology: think only of the “flash crash” of May 6 last year, when the Dow Jones industrial average plummeted 9 percent and then rallied in a matter of minutes.
Could the same kind of volatility spread into other markets as these become as wired and as integrated as Planet Finance? The answer must be yes. Consider how Greece’s fiscal woes have destabilized markets across Europe and around the world in recent months. Then there’s the market for consumer durables. We know that the speed with which new technologies have been adopted by American households has increased around eightfold over the past hundred years. But that speed of adoption has its obverse in the speed of obsolescence. Consumers are becoming ever more fickle. Millions bought RIM’s BlackBerry after its advent in 1999. But today the iPhone is the hotter handheld device, and I am far from alone in having a dead BlackBerry in my bottom desk drawer. In late September Amazon launched the Kindle Fire in a bid to challenge the iPad’s dominance of the tablet market. The name is appropriate. The market for such devices is on fire. The whole world is on wi-fire.
In politics, too, online electorates are becoming more volatile. The current race to find a Republican candidate for the presidency is a case in point. Only the other day Sarah Palin was a serious contender. Then Mitt Romney was a shoe-in. Until Rick Perry came along. Until Chris Christie came along. Meanwhile, the number of independent voters who have uncoupled themselves from the traditional parties has reached a historic high of 37 percent. Floating voters are the high-frequency traders of the political market.
Computing power has grown exponentially. So has the human network. But the brain of Homo sapiens remains pretty much the same organ that evolved in the heads of African hunter-gatherers 200,000 years ago. And that brain has a tendency to swing in its mood, from greed to fear and from love to hate.
The reality may be that by joining us all together and deluging us with data, the Netlords have ushered in a new Age of Volatility, in which our primeval emotions are combined and amplified as never before.
We are LinkedIn, but StressedOut. And that “cloud” of downloadable data may yet turn out to be a thundercloud.

Cyborgs in Latin America

Cyborgs in Latin America - J. Andrew BrownCyborgs in Latin America explores the ways cultural expression in Latin America has grappled with the changing relationships between technology and human identity. The book takes a literary and cultural studies approach in examining narrative, film and advertising campaigns from Argentina, Bolivia, Chile, Mexico and Uruguay by such artists as Ricardo Piglia, Edmundo Paz Soldán, Carmen Boullosa and Alberto Fuguet among others.  Using and criticizing theoretical models developed by Katherine Hayles, Donna Haraway, Gilles Deleuze and Michel Foucault, the book will appeal to specialists and students of Latin American Studies; Posthuman Theory; and Literature, Science and Technology Studies.

Las Redes Sociales, las nuevas armas de resistencia en Chile

Las Redes Sociales, las nuevas armas de resistencia en Chile
Por Omar Mendoza. 26/08/2011 Política&Medios.
Los twitteros y los usuarios de Facebook chilenos han demostrado que el debate cibernético puede tener su reflejo en la realidad.


En los últimos tiempos hemos podido observar el inmenso poder de convocatoria y organización política  y social que tienen como protagonistas a  las redes como Twitter o Facebook. La “Primavera Árabe”, que se organizó para repudiar los regímenes de esa región,  las protestas de los “indignados” españoles, que luchan contra la corrupción y la devaluación de la política, y la intensa actividad de coordinación llevada a cabo por los estudiantes en Chile es un ejemplo claro de esta tendencia.

A nadie se le escapa que Twitter, en los últimos tiempos, se ha convertido en un buen termómetro para analizar como respira la sociedad de un país sobre una cuestión concreta. En este sentido, por el gran número de comentarios que se acumulan en relación a las protestas estudiantiles que sacuden Chile desde hace varios meses, todo parece indicar que, lejos de apagarse, el debate está más vivo que nunca. Prácticamente todos los días en las últimas semanas los “Trending Topics” chilenos han estado dominados por el conflicto estudiantil. Facebook, sin embargo, al ser más privado convierte su tráfico de información en menos visible para las autoridades, pero igualmente efectivo.

Los estudiantes chilenos están decididos a continuar con sus protestas contra el Gobierno de Sebastián Piñera y en favor de una educación gratuita y de calidad. Precedida por una intensa actividad en Twitter y las redes sociales, Santiago vivió ayer, una nueva jornada masiva de movilizaciones de universitarios, secundarios y profesores, cuya asistencia alcanzó, según los organizadores, la abultada cifra de 100.000 personas y que ha tenido su reflejo cibernético en la etiqueta #marchadelosparaguas.

Por su parte, esta semana Felipe Bulnes, ministro de Educación, ha lanzado una propuesta que sigue sin convencer a los estudiantes pero que recoge varias de sus reclamaciones. Por un lado, la ampliación de la oferta de becas y créditos para que los estudiantes tengan un acceso más igualitario a la educación, lo que incluye una reducción de los intereses del préstamo estatal de un 6% a un 2%; por otro, poner fin al lucro en el sector, reducir su municipalización y una reforma constitucional que garantice la calidad en la educación. Una propuesta que a los estudiantes sigue sin convercerles y que no ha podido parar la movilización de hoy, ampliamente planeada a través de una intensa actividad en Twitter y otras redes sociales.

El sistema educativo chileno ha sido heredado por la democracia de la dictadura de Augusto Pinochet y mantiene unas elevadas tasas que impiden a los estudiantes con menos recursos acceder a la educación superior. Si lo hacen, deben soportar varios años de alto endeudamiento para poder pagar sus estudios. Además, los estudiantes reclaman que el Estado se ocupe del sector, y no los municipios, y que la educación, una de las más caras del mundo según la OCDE, sea gratuita y accesible universalmente para todos los ciudadanos.

El conflicto se ha hecho crónico en el peor momento posible para Sebastián Piñera, cuya popularidad se ha desplomado de manera vertiginosa en los últimos meses por la conflictividad social que asola Chile desde que inició su mandato. Ecologistas, mineros, estudiantes y grandes partes de la ciudadanía ven con malos ojos su gestión, que según los últimos sondeos ha alcanzado un 52% de desaprobación. Sin embargo, el dato más sangrante es el de su popularidad, que ha vuelto a caer y se sitúa en un 26%, la peor valoración jamás dada a un líder chileno en las últimas dos décadas. El poder de las redes sociales y de la transmisión de información ha contribuido sin duda a que entre la población chilena circulen corrientes de opinión que se oponen al presidente.

Radiografía en Twitter al movimiento estudiantil: Los peaks y rostros que la llevan en la red


Radiografía en Twitter al movimiento estudiantil: Los peaks y rostros que la llevan en la red.

19/08/2011 - LaSegunda.
La consultora Brandmetric estudió el impacto del movimiento estudiantil en Twitter: Una de las conclusiones es que las menciones en la red social subieron cuando las manifestaciones fueron más violentas.



Cuando muchos -Gobierno, partidos, Parlamento y medios, entre otros- se preguntan hacia dónde va el movimiento estudiantil y su estrategia de movilización social, la empresa consultora Brandmetric estudió el impacto de estas marchas en las redes sociales, graficando la fuerza que ha tenido este concepto en Twitter.

La cantidad de menciones que obtuvieron las protestas en Twitter y los temas más comentados al respecto -"trending topics"- en Chile, son los principales resultados del análisis, y que muestran cómo ha tenido una fuerza más sostenida que la que alcanzó en las redes sociales el debate por el proyecto HidroAysén, ratificando también que en el mundo web nombres como Camila Vallejo y Giorgio Jackson la llevan al determinar las palabras más utilizadas.
Concepto duplica menciones del tema que le sigue
Según el fundador de Brandmetric, Carlos Orrego, "comparativamente con los más de 100 seguimientos que realizamos actualmente, el tema del «Movimiento Estudiantil» ha copado las redes sociales el último mes en cantidad de menciones, más que duplicando a quien le sigue, que es el Presidente Sebastián Piñera".
En una de las primeras marchas estudiantiles, la del l de junio -cuando adhirieron rectores emblemáticos- hubo 4.413 menciones Twitter al conflicto, mientras que las palabras "marcha estudiantil", "educación" y "Confech" se convirtieron en los tópicos más usados.
Estos números, una vez que el movimiento adquirió fuerza, fueron al alza. El 16 de junio, cuando la jornada de protesta copó la Alameda entre Portugal y Plaza Los Héroes, las menciones subieron a 11.313. "Marcha", "Giorgio Jackson" y "deuda" fueron en aquella ocasión las palabras más tuiteadas.
El 30 de junio, cuando marcharon cerca de 100 mil personas en todo el país -en lo que fue catalogado como la movilización más grande en los últimos 20 años- las menciones subieron a 11.635. El número de personas en las calles no pasó desapercibido, pues los principales "trending topics" fueron "100.000" y "asistentes".
A más desmanes más menciones
Sin embargo, las menciones llegaron a su "peak" con las dos marchas más polémicas protagonizadas por el movimiento estudiantil en el centro de Santiago.
La primera fue el 4 de agosto, cuando una movilización no autorizada terminó con duros enfrentamientos entre los estudiantes y la fuerza pública: 28.092 menciones, con "Camila" (por Vallejo); "cacerolazo" y "Giorgio Jackson" como las palabras clave más usadas en Chile ese día.
Mismo fenómeno pasó el 9 de agosto, cuando una movilización -esta vez autorizada- terminó con serios destrozos en el barrio de la Plaza Bulnes: 21.492 twitts y "movimiento estudiantil" "Camila" y "frutoprohibido#" (por el programa de TVN en que participó Vallejo esa noche) fueron los conceptos más repetidos.
"Estos días se produjo el efecto amplificador más importante del movimiento estudiantil en las redes sociales. La represión y violencia generaron mayores niveles de conversación", explica Orrego.
Más que HidroAysén
Brandmetric también hizo la comparación de las marchas con otro de los movimientos sociales que explotaron durante este año: el rechazo a la hidroeléctrica HidroAysén. Este, según el análisis, no causó el mismo revuelo que las movilizaciones estudiantiles, como lo muestra el gráfico principal.




Riots database of 2.5m tweets reveals complex picture of interaction


Riots database of 2.5m tweets reveals complex picture of interaction.

24/08/2011. Guardian.co.uk 
When David Cameron addressed an emergency session of parliament convened in the aftermath of four consecutive nights of rioting and looting across England, he quickly turned to the supposed role played by social media.
"Everyone watching these horrific actions will be struck by how they were organised via social media," the prime minister told the House. "We are working with the police, the intelligence services and industry to look at whether it would be right to stop people communicating via these websites and services when we know they are plotting violence, disorder and criminality."
His claims were backed by some MPs and senior police, who revealed they had considered switching off social network sites at the height of the disturbances, but were unsure of their legal powers.
Yet preliminary analysis of how Twitter was used during the unrest presents a more complex picture, showing little immediate evidence that the social network was used to orchestrate disorder.
The Guardian has compiled a unique database of more than 2.5m tweets containing keywords, phrases and hashtags linked to England's riots.
Preliminary analysis of this Twitter activity in 12 riot locations shows the majority of surging social media traffic occurs after the first verified reports of incidents in an area, which could suggest that Twitter was used far more by those seeking to follow fast-moving events than to incite trouble – although it is not possible to say it played no role.
The tweets also reflect a shift in social media use during the week. Most reports place the initial disturbances in Tottenham between 8pm and 9pm on Saturday night. The number of tweets referencing the area surged in the wake of these first troubles: up from 15 between 7pm and 8pm to 15,000 between 10pm and 11pm.
Later in the week Twitter may even have helped spread warnings about trouble. On the following Tuesday Greater Manchester police gave a press conference at 2pm warning of potential issues later that day. This was mirrored by tweets mentioning the city jumping to over 1,000 an hour before trouble began, peaking at around 12,000 an hour after disturbances had started.
In areas such as Hackney Twitter filled with reports of stores closing early and police presence building in the area, hours ahead of the outbreak of trouble.
The Guardian database, which contains riot-related tweets sent between midnight on 6 August – the day riots began in Tottenham – and 8pm on 17 August, will be subject to more advanced analysis in the coming weeks as part of an ongoing investigation into the riots.
Several Facebook users have already been imprisoned for their use of the service during the unrest.
Two men who attempted to use Facebook to arrange riots, which did not materialise, were sentenced to four years in prison, while David Glyn Jones, 21, who posted: "Given the chance I'd love to smash up a police car, wouldn't you?", was sentenced to four months. The prime minister said he supported the "tough message" the court rulings had sent out.
Anecdotal evidence suggests BlackBerry Messenger was also used by some rioters to disseminate messages inciting unrest. However, the free pin-protected service, popular among young people, was also used extensively by those seeking to avoid trouble.
Executives from Facebook, Twitter and the BlackBerry manufacturer RIM, who have been resisting calls to shut down their networks, are to meet the home secretary to discuss further action.

¿Han tocado techo las redes sociales?


¿Han tocado techo las redes sociales?


Cada vez más voces aseguran que Facebook ha llegado a su cénit. Y según un reciente estudio internacional de la empresa de investigación de mercados Gartner, esta afirmación parece tener una base real.
Para la realización del informe,Gartner entrevistó a más de 6.000 internautas de 11 países. El 24% de los 
consultados, fundamentalmente usuarios muy afines a las nuevas tecnologías, admitió conectarse a su red social favorita con menos frecuencia que al principio.
Asimismo, el 31% de los consultados, internautas jóvenes y afines a la tecnología móviles y a las marcas, reconoció haberse cansado de las redes sociales.
El hartazgo de los internautas varía, de todas formas, en función de su nacionalidad. En Japón, Reino Unido y Estados Unidos, una quinta de los parte de los internautas se conecta a las redes social con menos frecuencia que al comienzo del “boom 2.0”. Sin embargo, el 40% de los usuarios siguen siendo fieles a Facebook y compañía.
Los más cansados de la Web Social son los rusos y los brasileños. Así, el 40% de los internautas de Rusia y el 30% de los usuarios de Brasil admiten utilizar las redes sociales con menos asiduidad que hace unos meses.

Social Networking’s Good and Bad Impacts on Kids


Social Networking’s Good and Bad Impacts on Kids

August 6, 2011. APA.org

Psychologists explore myths, realities and offer guidance for parents
WASHINGTON—Social media present risks and benefits to children but parents who try to secretly monitor their kids’ activities online are wasting their time, according to a presentation at the 119th Annual Convention of the American Psychological Association.
“While nobody can deny that Facebook has altered the landscape of social interaction, particularly among young people, we are just now starting to see solid psychological research demonstrating both the positives and the negatives,” said Larry D. Rosen, PhD, professor of psychology at California State University, Dominguez Hills.
In a plenary talk entitled, “Poke Me: How Social Networks Can Both Help and Harm Our Kids,” Rosen discussed potential adverse effects, 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, preteens and teenagers by making them more prone to anxiety, depression, and other psychological disorders, as well as by 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 said 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 behind the safety of various screens, ranging from a two-inch smartphone to a 17-inch laptop. 
  • Social networking can provide tools for teaching in compelling ways that engage young students.
For parents, Rosen offered guidance. “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 said. “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.”
He encouraged parents to assess their child’s activities on social networking sites, and discuss removing inappropriate content or connections to people who appear problematic. Parents also need to pay attention to the online trends and the latest technologies, websites and applications children are using, he said.  
“Communication is the crux of parenting. You need to talk to your kids, or rather, listen to them,” Rosen said. “The ratio of parent listen to parent talk should be at least five-to-one. Talk one minute and listen for five.”
Plenary Session: 3378, 4:00 - 4:50 p.m., Saturday, Aug. 6, Walter E. Washington Convention Center, Street Level, Room 147 B.

The American Psychological Association, in Washington, D.C., is the largest scientific and professional organization representing psychology in the United States and is the world's largest association of psychologists. APA's membership includes more than 154,000 researchers, educators, clinicians, consultants and students. Through its divisions in 54 subfields of psychology and affiliations with 60 state, territorial and Canadian provincial associations, APA works to advance psychology as a science, as a profession and as a means of promoting health, education and human welfare.
