This demonstration shows that even mild preferences to be near members of one's own group can lead to extreme segregation.
■Segregation is the separation of social groups by race, class, ethnicity, gender, or other recognizable characteristics.■Residential segregation refers to segregation in housing, whereas school segregation refers to differential access to educational facilities.Segregation: Schelling Effect■prejudice can lead to segregation■homophily leads to segregation■ to the separation of groups by race, gender, or other social categories■It was this type of segregation that Rosa Parks fought in 1955 when she refused an Alabama bus driver's demand that she move to the rear with other Black riders.■why does segregation still occur today in schools and other places where people support social equalityNobel Laureate Thomas Schelling proposed an answer in the 1970s, writing that racial discrimination arises not only from behavior that is "heartless, selfish and illegal" but "from the magnification of small incentives into massive results."

Applications: The goal of this unit is providing practical examples of how network projects tackle relevant social issues
Le8 - Fri Oct. 23, 2020 The relation between personality, structural position in the network and productivity.
Le10 - Fri Oct. 30, 2020 The CAN (Causal Attitude Network) model conceptualizes attitudes as networks consisting of evaluative reactions and interactions between these reactions.
Le14 - Fri Nov. 13, 2020 An application of network analytics to collective action. The relation between network types, motivation, and participation. Insights about removal effectiveness (and network robustness) in relation to removal type (targets vs. random), type of network, and collective emotions.
Le15 - Thu Nov. 19, 2020 A field experiment showing the power of small manipulation in the context of voting behaviors. Social contagion spreads faster across strong ties, with important consequences for the political involvement of crowds.
Le20 - Thu Dec. 10, 2020 Semantic networks: issues about text retrieval, mining and coding. Focus on linguistic cues of psychological processes and inter group relations. Presentation of the case study of climate change activism: investigation of a semantic network of tweets
