  • The Strength of Weak Ties
  • 1973 paper
  • people are more likely to acquire jobs that they learned about through individuals they interact with infrequently rather than their close personal
  • We are connected to core groups of strong ties that we interact with frequently and weak ties that we interact with infrequently

      Moreno (1951:1931)
  • the "strength of weak ties" states that weak ties facilitate information flow from disparate clusters of people

      Innovation related to distant people (weak connections)
  • tight-knit social circles tend to be small relative to people's entire social network, and when it comes to information about future job opportunities, it can be hard to find new leads.
  • Weak ties help spread novel information by bridging the gap between clusters of strong tie contacts
  • homophily [3], the tendency of individuals with similar characteristics to associate with one another.
    • enrique garcia
       
      Inbreeding (Endogamia)
  • Individuals are connected to each other through workplaces, professions, schools, clubs, hobbies, political beliefs and other affiliations.  The homophily principle holds true for any kind of social network you can think of:
  • even the people you ride the bus with.
  • these commonalities not only shape how often people interact and what they talk about, but also what kinds of information they as individuals seek on the Web.
  • Homophily suggests that people who interact frequently are similar and may consume more of the same information. 
  • Individuals that interact less often tend to be dissimilar and may consume more diverse information. 
  • We found that people are more likely to share the information they were exposed to by their strong ties than by their weak ties on Facebook (Figure 3).   
  • strength between two individuals is measured by the number of comments a person received from their friend on Facebook
  • Other measurements of tie strength, like the number of messages, co-appearances in photos, and discussion on posts are discussed in our paper [5].
  • There are many possible explanations for the increased flow of information across strong ties
  • information shared by a person's weak ties is unlikely to be shared at a later point in time independently of those friends.
  • seeing content from a weak tie leads to a nearly tenfold increase in the likelihood that a person will share a link
  • In contrast, seeing information shared by a strong tie in News Feed makes people just six times as likely to share.
  • weak ties have the greatest potential to expose their friends to information that they would not have otherwise discovered.
  • though a person is more likely to share a single piece of information from one of their close contacts,
  • weak ties are collectively responsible for the majority of information spread. 
  • example (illustrated in Figure 5). Let's say a person has 100 contacts that are weak tie friends, and 10 that are strong tie friends.  Suppose the chance that you'll share something is very high for strong tie friends, say 50%
  • but the weak tie
  • sharing is only 15%
  • Therefore the amount of information spread due to weak and strong ties would be 100*0.15 = 15, and 10*0.50 = 5 respectively
  • so in total, people would end up sharing more from their weak tie friends.
  • because of their abundance, weak ties are primarily responsible for the majority of information spread on Facebook.
  • majority of people’s contacts are weak tie friends
  • We are exposed to and spread more information from our distant contacts than our close friends.
  • Since these distant contacts tend to be different from us, the bulk of information we consume and share comes from people with different perspectives
  • Our work
  • shows that online social networks can serve as an important medium for sharing new perspectives, products and world events.
  • very often, information does not "cascade" very far along the network.  This phenomenon has been observed in earlier research on Twitter in Everyone's an Influencer: Quantifying Influence on Twitter
  • and has been studied across other networks
  • by Sharad Goel and Duncan Watts at Yahoo! Research, NY.
  • person who click 'like' is in the weak ties group, and then who write a reply is in the strong ties group ?
  • share opinion , please

      Not necesarily but it's a good idea to assess FB behaviour.

    Digital Vaults gives you and your kids a place to find raw materials that are arranged in ways that may make more sense to them. The site is set up a bit like a social network. Data is organized by tags and linked to both the tags as well as other resources. Like a social network, you can make your favorites documents / materials your "friends," search for new "friends" by using tags and create "mashups" using primary sources.

H.264/MPEG-4 AVC - Wikipedia, the free encyclopedia - 0 views

  •  
    The intent of the H.264/AVC project was to create a standard capable of providing good video quality at substantially lower bit rates than previous standards (e.g. half or less the bit rate of MPEG-2, H.263, or MPEG-4 Part 2), without increasing the complexity of design so much that it would be impractical or excessively expensive to implement. An additional goal was to provide enough flexibility to allow the standard to be applied to a wide variety of applications on a wide variety of networks and systems, including low and high bit rates, low and high resolution video, broadcast, DVD storage, RTP/IP packet networks, and ITU-T multimedia telephony systems.

Social Networking - Let's Start Early « The Spicy Learning Blog - 10 views

  • The less we work with students on being critically literate online, and the more we avoid social media and networking as an authentic part of the classroom experience, the more danger our students will be in.
  • Let’s not wait until high school when they are perceived to be old enough. If we wait until then, we will have to do more untraining of bad habits students have picked up Facebooking etc.
  • From my experience, although I don’t think any age is too early, I have noticed that ages 8-10 are the perfect time to start.

Teachers Lead Adoption of Web 2.0, but Perceptions Stifle Social Networking : April 200... - 0 views

  • What's more, district technology leaders also reported district network and data security concerns (35 percent), limited support systems (35 percent), and student "safety" concerns (76 percent) among the technology barriers to the adoption of social networking.
    • Chris Harkness
       
      Limited support systems could be insufficient bandwidth and resources (to protect data if network is "opened up") as well as lack of knowledge and training for tech staff and teachers.

The AI Avatar Transfer to Augmented Reality May Be So Subtle We Won't Notice the Rapid ... - 0 views

  • It seems these days that many people have blurred their virtual world with the real world. If you doubt what I'm saying, why not stand in line at the airport, the DMV, or even at Starbucks and just count how many people are on their smart phones or personal tech devices busy texting their friends, checking other social networks, or reading news online. I imagine with the number of people busy online these days, you could easily cut in line and no one would be the wiser.

Why build a Personal Learning Network? - 0 views

  •  
    'Inside the Black Box' was written by Black and William in 1998 and in it they describe the classroom as a black box with inputs and outputs but what occurred inside was a mystery. For many teachers the reality has been that what occurs in their classroom has been both private and isolating, a matter between the teacher and his or her students but a task largely tackled alone. But this isolationist view is, in the age of the social media and networking increasingly challenged and more and more teachers are finding their voice, sharing their ideas and gaining valuable insights from a global community of connected educators.

What Kids Learn from Social Networking | 21st Century Connections - 0 views

  •  
    Researchers at the University of Minnesota have documented the educational benefits of social networking sites such as MySpace and Facebook. Students observed for the study listed technology skills as the top lesson learned, followed by creativity, being open to new or diverse views and communication skills Data were collected over six months this year from students, ages 16 to 18, in thirteen urban high schools in the Midwest. Beyond the surveyed students, a follow-up, randomly selected subset were asked questions about their Internet activity as they navigated MySpace, an online forum that provides users with e-mail, web communities and audio and video capabilities.
