Bridge (interpersonal)
A bridge is a type of social tie that connects two different groups in a social network. General bridge In general, a bridge is a direct tie between nodes that would otherwise be in disconnected components of the graph. This means that say that A and B make up a social networking graph, n_1 is in A, n_2 is in B, and there is a social tie e between n_1 and n_2. If e were to be removed, A and B would become disconnected components of the graph. This means that e is a bridge. For example, A could represent a corporation and B Congress. n_1 could then be a lobbyist and n_2 a Congressman. e would then represent the relationship between that corporation and Congress that only exists through the lobbyist. This is very similar to the concept of a bridge in graph theory, but with special social networking properties such as strong and weak ties. Local bridge Local bridges are ties between two nodes in a social graph that are the shortest route by which information might travel from th ...

Social Network
A social network is a social structure consisting of a set of social actors (such as individuals or organizations), networks of Dyad (sociology), dyadic ties, and other Social relation, social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities along with a variety of theories explaining the patterns observed in these structures. The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and examine dynamics of networks. For instance, social network analysis has been used in studying the spread of misinformation on social media platforms or analyzing the influence of key figures in social networks. Social networks and the analysis of them is an inherently Interdisciplinarity, interdisciplinary academic field which emerged from social psychology, sociology, statistics, and graph theory. Georg Simmel authored early structural th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridge (graph Theory)
In graph theory, a bridge, isthmus, cut-edge, or cut arc is an Glossary of graph theory#edge, edge of a Graph (discrete mathematics), graph whose deletion increases the graph's number of Connected component (graph theory), connected components. Equivalently, an edge is a bridge if and only if it is not contained in any Cycle (graph theory), cycle. For a connected graph, a bridge can uniquely determine a Cut (graph theory), cut. A graph is said to be bridgeless or isthmus-free if it contains no bridges. This type of bridge should be distinguished from an unrelated meaning of "bridge" in graph theory, a subgraph separated from the rest of the graph by a specified subset of vertices; see Glossary of graph theory#bridge, bridge in the Glossary of graph theory. Trees and forests A graph with n nodes can contain at most n-1 bridges, since adding additional edges must create a cycle. The graphs with exactly n-1 bridges are exactly the tree (graph theory), trees, and the graphs in which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weak Ties
In social network analysis and mathematical sociology, interpersonal ties are defined as information-carrying connections between people. Interpersonal ties, generally, come in three varieties: ''strong'', ''weak'' or ''absent''. Weak social ties, it is argued, are responsible for the majority of the embeddedness and structure of social networks in society as well as the transmission of information through these networks. Specifically, more novel information flows to individuals through weak rather than strong ties. Because our close friends tend to move in the same circles that we do, the information they receive overlaps considerably with what we already know. Acquaintances, by contrast, know people that we do not, and thus receive more novel information. Included in the definition of ''absent ties'', according to the American sociologist Mark Granovetter, are those relationships (or ties) without substantial significance, such as "nodding" relationships between people livin ...

Social Graph
A social graph is a graph that represents social relations between entities. It is a model or representation of a social network. The social graph has been referred to as "the global mapping of everybody and how they're related". The term was used as early as 1964, albeit in the context of isoglosses. Leo Apostel uses the term in the context here in 1978. The concept was originally called sociogram. The term was popularized at the Facebook F8 conference on May 24, 2007, when it was used to explain how the newly introduced Facebook Platform would take advantage of the relationships between individuals to offer a richer online experience. The definition has been expanded to refer to a social graph of all Internet users. Since explaining the concept of the social graph, Mark Zuckerberg, one of the founders of Facebook, has often touted Facebook's goal of offering the website's social graph to other websites so that a user's relationships can be put to use on websites outsi ...

Malcolm Gladwell
Malcolm Timothy Gladwell (born 3 September 1963) is a Canadian journalist, author, and public speaker. He has been a staff writer for ''The New Yorker'' since 1996. He has published eight books. He is also the host of the podcast ''Revisionist History (podcast), Revisionist History'' and co-founder of the podcast company Pushkin Industries. Gladwell's writings often deal with the unexpected implications of research in the social sciences, such as sociology and psychology, and make frequent and extended use of academic work. Gladwell was appointed to the Order of Canada in 2011."Governor General Announces 50 New Appointments to the Order of Canada" The Governor General of Canada, 30 June 2011.

Connector (social)
''The Tipping Point: How Little Things Can Make a Big Difference'' is the debut book by Malcolm Gladwell, first published by Little, Brown in 2000. Gladwell defines a tipping point as "the moment of critical mass, the threshold, the boiling point." The book seeks to explain and describe the "mysterious" sociological changes that mark everyday life. As Gladwell states: "Ideas and products and messages and behaviors spread like viruses do." The examples of such changes in his book include the rise in popularity and sales of Hush Puppies shoes in the mid-1990s and the steep drop in New York City's crime rate after 1990. The three rules Gladwell describes the "three rules of epidemics" (or the three "agents of change") in the tipping points of epidemics. The Law of the Few "The Law of the Few" is, as Gladwell states: "The success of any kind of social epidemic is heavily dependent on the involvement of people with a particular and rare set of social gifts." According to Gladwell, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
