Social Media and the ‘Spiral of Silence’


Summary of Findings

A major insight into human behavior from pre-internet era studies of communication is the tendency of people not to speak up about policy issues in public—or among their family, friends, and work colleagues—when they believe their own point of view is not widely shared. This tendency is called the “spiral of silence.”
Some social media creators and supporters have hoped that social media platforms like Facebook and Twitter might produce different enough discussion venues that those with minority views might feel freer to express their opinions, thus broadening public discourse and adding new perspectives to everyday discussion of political issues.

Social Networking Fact Sheet


The average Facebook user gets more from their friends on Facebook than they give to their friends. Why? Because of a segment of “power users,” who specialize in different Facebook activities and contribute much more than the typical user does.

Power user

0Wikipedia-logo-en-bigA power user is a personal computer user who uses advanced features of programs which are not used by the average user. A power user is not necessarily capable of computer programming and system administration. In enterprise software systems, this title may go to an individual who is not a programmer, but who is a specialist in business software. Often these are people who retain their normal user job role, but also function in testing, training, and first-tier support of the enterprise software.
Users may erroneously label themselves as power users when they are less than fully competent.

Are You a Facebook Power User?

Are you among the 20-30% of the Facebook population that’s considered power users? If you’ve logged in to the social network already today, there’s a good chance you are one of the addicted elite.
This infographic, created by DemandForce, details what it means to be a Facebook power user. For starters, you likely kick butt at basic F-book activities, like sending friend requests, commenting and pressing the “Like” button. Sounds pretty basic, right?
On the contrary, only 5% of users excel in four or more of the core Facebook actions. Still convinced you’re at the top?

Facebook dominated by ‘power users’

  • The majority of Facebook activity is carried out by a minority of users, according to a new study.

Most people using the social network receive more interactions, such as ‘likes’ or being tagged in photos, than they give out on the site.
A new study entitled: ‘Why Most Facebook Users Get More Than They Give’, from Pew Internet, an American not-for-profit research firm, found that people ‘liked’ other Facebook members’ content an average of 14 times, while their own content was on average ‘liked’ 20 times.
Twelve per cent of Pew’s study participants, over the course of a month, tagged friends in photos, but then 35 per cent were themselves tagged in minimum of one photo. On average they sent nine personal messages and received 12. Forty per cent of them made a ‘friend request’, while 63 per cent received one in that time.
“First, it turns out there are segments of Facebook power users who contribute much more content than the typical user,” explained Professor Keith Hampton, the lead author of the report.

Facebook IPO: your data just became more valuable

By Emma Barnett, Digital Media Editor
3:50PM GMT 02 Feb 2012

  • Facebook’s IPO, which is expected to see the company be valued at $100bn, has put it under more pressure to aggressively sell its’ users data, according to leading digital agency chiefs.

Despite money generated from advertising accounting for 85 per cent of Facebook’s revenues last year, and its net income in 2011 reaching $1billion, the company will have to radically change the way it cashes in on its users’ data to make good on its valuation, says digital agency heads.
Charlie McGee, head of digital at Carat, a major UK advertising agency, thinks Facebook will follow Google’s AdSense model, and start selling adverts to its members through the 40 million plus sites which have already plugged in Facebook Connect.
“More than 40 million websites have installed the ‘Like’ button across the internet, so the infrastructure and technology is already there for Facebook to start capitalising on its users’ data away from the social networking site,” he explains.

Twitter ‘elite’ send most tweets

  • Only a small elite group of elite Twitter users are generating half of the tweets shared on the service, according to new research.

Fifty per cent of all tweets read and shared on Twitter are generated by only 20,000 ‘elite’ users, despite there being more than 200 million registered accounts on the service.
Yahoo! researchers looked at 260 million tweets posted on Twitter between July 28, 2009 and March 8, 2010, and by using Twitter ‘lists’, were able to distinguish between elite users – specifically celebrities, bloggers, and representatives of media outlets and other formal organizations, and ordinary users.
“Based on this classification, we find a striking concentration of attention on Twitter – roughly 50 per cent of tweets consumed are generated by just 20,000 elite users- where the media produces the most information, but celebrities are the most followed,” a Yahoo! researcher said.

Why most Facebook users get more than they give


About this study

The Pew Research Center’s Internet & American Life Project fielded a nationally representative phone survey about the social and civic lives of SNS users and reported the findings in June 2011 in a report entitled “Social networking sites and our lives.”1 During the phone survey, 269 of 877 original respondents who were Facebook users gave us permission to access data on their use of Facebook so that it could be matched with their survey responses. We partnered with Facebook to match individual responses from the survey with profile information and computer logs of how those same people used Facebook services over a one-month period in November 2010 that overlapped when the survey was in the field.

The tone of life on social networking sites

The overall social and emotional climate of social networking sites (SNS) is a very positive one where adult users get personal rewards and satisfactions at far higher levels than they encounter anti-social people or have ill consequences from their encounters. A nationally representative phone survey of American adults finds that…

How Scientists Engage the Public

American scientists believe they face a challenging environment and the vast majority of them support the idea that participation in policy debates and engagement with citizens and journalists is necessary to further their work and careers.
A survey of 3,748 American-based scientists connected with the American Association for the Advancement of Science (AAAS) finds that 87% agree with the statement “Scientists should take an active role in public policy debates about issues related to science and technology.” Just 13% of these scientists back the opposite statement: “Scientists should focus on establishing sound scientific facts and stay out of public policy debates.”

Public and Scientists’ Views on Science and Society

Scientific innovations are deeply embedded in national life — in the economy, in core policy choices about how people care for themselves and use the resources around them, and in the topmost reaches of Americans’ imaginations. New Pew Research Center surveys of citizens and a representative sample of scientists connected to the American Association for the Advancement of Science (AAAS) show powerful crosscurrents that both recognize the achievements of scientists and expose stark fissures between scientists and citizens on a range of science, engineering and technology issues. This report highlights these major findings…

U.S. Views of Technology and the Future

Science in the next 50 years


The American public anticipates that the coming half-century will be a period of profound scientific change, as inventions that were once confined to the realm of science fiction come into common usage. This is among the main findings of a new national survey by the Pew Research Center and Smithsonian magazine, which asked Americans about a wide range of potential scientific developments—from near-term advances like robotics and bioengineering, to more “futuristic” possibilities like teleportation or space colonization. In addition to asking them for their predictions about the long-term future of scientific advancement, we also asked them to share their own feelings and attitudes toward some new developments that might become common features of American life in the relatively near future.

Public’s Knowledge of Science and Technology

The public’s knowledge of science and technology varies widely across a range of questions on current topics and basic scientific concepts, according to a new quiz by the Pew Research Center and Smithsonian magazine. Click here to take the quiz yourself before reviewing the answers.
4-22-13 #1 About eight-in-ten Americans (83%) identify ultraviolet as the type of radiation that sunscreen protects against. Nearly as many (77%) know that the main concern about the overuse of antibiotics is that it can lead to antibiotic-resistant bacteria.
However, only about half (51%) of the public knows that “fracking” is a process that extracts natural gas, not coal, diamonds or silicon from the earth.

The myth of “Power Users” at Wikipedia

By Tim Davenport /// “Carrite” (Wikipedia username) /// “Randy from Boise” (Wikipediocracy username) with some modest assistance from Yerucham Turing

Of course this assumes that the community of volunteers that actually built the encyclopedia and governing apparatus behind the encyclopedia, are nothing but the Most Highly Perfected editing drones created by their Bay Area masters — who hold all the cards and call all the shots.

This is a matter of fundamental importance.

I was thinking during the Mediaviewer/Superprotection fiasco that it had finally sunk in with the WMF circle jerkers that the Wikipedia Volunteer Community was indeed a real entity, to be dealt with on the basis of partnership. No such luck. Get a load of the following slide from a presentation at the WMF Sept. 25 Mobil Metrics meeting held at Club Headquarters in San Francisco:

sinapsis de redes semanticas

Probablemente sabes que Google es una de las empresas y marcas más valiosas del mundo, también has de saber que empezó como un buscador y que gran parte de su éxito se debe a la fórmula matemática (algoritmo) que usa en las búsquedas de información, pero lo que es casi seguro que no conoces es ese algoritmo. Mmm…¿No te recuerda este asunto a Coca-Cola con su mítico secreto acerca de su fórmula? Los que saben de esto dicen que el método que emplea Google cambia constantemente.

Si alguna vez has buscado un producto o comprado algo en Internet habrás notado que te hacen recomendaciones sobre otros productos similares al que buscabas o compraste. Por ejemplo, en Amazon siempre te dicen algo parecido a “Las personas que compraron este libro también compraron X o Y libros”. La verdad, esas recomendaciones son muy útiles aunque a veces perjudiciales para tu economía. | Análisis Estructural de redes Semánticas

Un libro infantil agita el racismo en Costa Rica


Un libro infantil agita el racismo en Costa Rica

Un cuento tradicional compara a un niño negro con un mono

La diputada costarricense Epsy Campbell, el pasado jueves en Uruguay. / EFE

“Uuuu, uuuu, uuuu”, imitaba a un mono un aficionado desde la grada para insultar a un futbolista rival negro. Cuando otro hincha lo encaró, la novia le recordó que semanas atrás habían castigado en ese mismo estadio, en la ciudad de Alajuela, en Costa Rica, a otro espectador por proferir insultos racistas. El aficionado aceptó callar, pero le dijo a su novia que él no era racista, que sus sonidos de primate eran solo para intentar desconcentrar al futbolista rival.

Era domingo y en los periódicos del día se leían aún comentarios sobre racismo y sobre un libro infantil tradicional llamado Cocorí, una obra ficticia que compara a un niño negro con un monito, entre otros estereotipos. La obra, de un intelectual comunista de los años cincuenta, había inspirado un ensamble musical patrocinado por recursos públicos que fue suspendido después por solicitud de dos diputadas negras, las únicas dos entre 57 escaños de un país con un 7,8% de población que se autodefine afrodescendiente, según el censo oficial. Ellas piden también que se retire el libro de la lista de textos de lectura disponibles para las escuelas públicas.

John Glenn, who declared as a 77-year-old in a news conference from space that “to look out at this kind of creation out here and not believe in God is to me impossible,” says facts about scientific discovery should be taught in schools — and that includes evolution.

The astronaut, now 93 with fading eyesight and hearing, told The Associated Press in a recent interview that he sees no contradiction between believing in God and believing in evolution.

“I don’t see that I’m any less religious by the fact that I can appreciate the fact that science just records that we change with evolution and time, and that’s a fact,” said Glenn, a Presbyterian. “It doesn’t mean it’s less wondrous and it doesn’t mean that there can’t be some power greater than any of us that has been behind and is behind whatever is going on.”

The Financial Times executive education rankings, now in their 17th year, rate the best 75 open programmes and the best 85 customised programmes worldwide. Executive education offers non-degree programmes, either tailor-made for corporate customers (customised) or available to all working managers (open). The rankings are based on participants’ and clients’ satisfaction, the diversity of participants and faculty, and the schools’ international exposure.
Iese, third in the customised ranking for the past three years, overtook HEC Paris, the runner-up since 2009, and made it to the top of the ranking for the first time. Iese is rewarded for performing consistently well across all 15 criteria. While the school is ranked first for faculty diversity only, it is in the top 10 for all remaining criteria. It is second for preparation and third for programme design and value for money.

El nuevo ranking divulgado este miércoles, el más amplio publicado hasta ahora, compara el desempeño de estudiantes de secundaria en matemáticas y ciencia en 76 países. Hong Kong ocupa el segundo puesto, Corea del Sur el tercero y Japón y Taiwán comparten el cuarto.
Pero el informe va más allá y vincula la educación en cada país con el futuro de su economía.
¿Cuál sería el crecimiento de la economía de México, Argentina, Perú, Chile, Uruguay o Colombia si sus estudiantes llegaran a un nivel básico de competencia en matemáticas y ciencias?
El informe deja en claro que las fallas en educación no sólo cuestan oportunidades y futuro a millones de adolescentes latinoamericanos. También marca a fuego el futuro de la economía de todo un país.

Los estudiantes de 15 años de Singapur, Hong Kong y Corea del Sur ocuparon los mejores lugares en matemática y ciencia.

ABC entrevista a André Van der Merwe, el cirujano sudafricano que realizó con éxito el primer trasplante de pene del mundo. Desde que anunció esta cirugía pionera ha recibido centenares de peticiones de todo el mundo

–Este tipo de trasplante debe tener muchas connotaciones psicológicas. Un corazón, o un riñón, no los vemos, pero un órgano tan íntimo…

–Sí, eso es lo que ocurrió con un primer trasplante fallido en China. La piel del pene no estaba bien; estaba muriendo, aunque al parecer el interior estaba bien. Cuando la mujer del paciente lo vio, pidió que lo retiraran. En el caso de nuestro joven, su novia no ha tenido ningún problema y ni siquiera ha pedido atención psicológica. Hay que vigilar signos de depresión, porque la medicación puede generar psicosis. Quizá fuimos muy afortunados. Este chico es muy estable. Está feliz, y sobre todo muy agradecido.
