  • 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

      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.

      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.

  • The term disruptive technology was first coined by Clayton M. Christensen, a Harvard Business School professor. It is described as an innovation
  • that unexpectedly displaces an established technology.
  • By contrast, sustaining technologies, which improve the state of established devices, typically are viewed in a more favorable light.

    Many countries adopt the culture of research. The research provides solutions to many issues. Researchers ask questions to find the solution to such problems. Good questions increase the chances of the right answers. In contrast, bad questions get poor answers. Most of the time, these questions are of two types: Open and close-ended questions. Researchers use them to gather data for research. These two are vastly different from each other. The researcher needs to understand the differences between them. It also increases the chance of getting objective-based answers from the audience. In this article, we explain both types of questions. We also share their pros and cons. It increases the understanding of the reader about both of them.

    A literature review aims to get insights related to the research problem and dive into the discussion. The structure of literature review is something that needs close attention. Without having a good structure, you cannot ace the milestones, and your literature review cannot stand out. The easiest way to structure literature review is using 5 Cs. These 5 Cs are comprised of cite, compare, contrast, critique, and connect. Each C has a particular set of attributes that help you make a perfect design to structure literature review. If any of the C is found to be missing in your literature review, I assure that you will have to resubmit it after

    Academic achievement is the dream of every student, which is only possible with hard work. In this way, there are factors that lead to success and reduce hurdles. An effective way of teaching and clear communication are vital to achieving academic achievement. In contrast to it, family stress develops hurdles. Teachers, students and parents should focus on solutions and support an effective learning method to boost academic performance and ensure it. There is no rocket science other than hard work and attention to reduce these hurdles.
