Social Networks Groups & Networks Group - a collection of people that share a similar attribute or place. Ex) men, residents of Statesboro Social Network – a collection of people that are connected to other members within the network Node – specific individual in social network Tie – a connection between two nodes Mutual tie – connection where a contagion flows back and forth between two nodes Contagion – anything that spreads across the network. Ex) information, money, physical goods Network structure – the shape of a network formed by examining all of the connections between individuals at once. This is what we see when we look at a graph of a social network. o The network’s structure is often more important than the characteristics of the individuals with the network o Social networks allow groups to do things that disconnected collection of individuals could not. Transitivity – a transitive relationship between three people where each person is connected to the other two. Any single individual can have multiple transitive relationships within a network. Individuals within a social network who have high transitivity are deeply embedded within that network. Always think of a triangle!! o Two people in a relationship – dad Most intimate – no secrets, no politics, no such thing as taking sides o Three people in a relationship – triad Centrality – measures how many connections a person has within a network. o Individuals with many connections are more central to the network than their peers with few connections o When researchers graph out a social network, those with most connections are moved into the center of the graph, which is why having lots of connections is described as being central to the network. Our Friends’ Friends’ Friends Affect Us Hyperdyadic spread o When phenomena spread from person to person to person beyond individual’s direct social ties o Spread happens by: Induction – copy cat Homophily – birds of a feather flock together, do things to fit in with the group Confounds – there could be something that effects the study The Network has a Life of Its Own Social networks have properties and functions that are neither controlled nor even perceived by the people within them. Emergent Properties of Social Networks: o New attributes of a whole that arise from the interaction and interconnection of the parts
