Net-map Toolbox
The net-map toolbox is a social network analysis tool that uses interviews and mapping to help people understand, visualize, discuss, and improve situations in which many different actors influence outcomes. Social network analysis is a research approach used by scholars such as S.D. Berkowitz, Stephen Borgatti, Ronald Burt, Linton Freeman, Mark Granovetter, Nicholas Mullins, Anatol Rapoport, Stanley Wasserman, Barry Wellman, and Harrison White to better understand the implications of the position of individual actors in a social structure. Individuals create influence network maps using materials from a physical toolkit. Actor names are written on post-it notes and distributed on a large sheet of paper. Lines are drawn to link the actors and reveal how they are connected or not connected, and “influence towers” are built to reflect the relative power of each actor (the higher the influence tower, the greater the influence). Photos displaying these influence network maps are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Network Analysis
Social network analysis (SNA) is the process of investigating social structures through the use of networks and graph theory. It characterizes networked structures in terms of ''nodes'' (individual actors, people, or things within the network) and the ''ties'', ''edges'', or ''links'' (relationships or interactions) that connect them. Examples of social structures commonly visualized through social network analysis include social media networks, meme proliferation, information circulation, friendship and acquaintance networks, business networks, knowledge networks, difficult working relationships, collaboration graphs, kinship, disease transmission, and sexual relationships. These networks are often visualized through '' sociograms'' in which nodes are represented as points and ties are represented as lines. These visualizations provide a means of qualitatively assessing networks by varying the visual representation of their nodes and edges to reflect attributes of inter ...

Anatol Rapoport
Anatol Borisovich Rapoport (; ; May 22, 1911January 20, 2007) was an American mathematical psychologist. He contributed to general systems theory, to mathematical biology and to the mathematical modeling of social interaction and stochastic models of contagion. Biography Rapoport was born in Lozova, Kharkov Governorate, Russia (in today's Kharkiv Oblast, Ukraine) into a secular Jewish family.

Barry Wellman
Barry Wellman (30 September 1942 – 9 July 2024) was an American-Canadian sociologist and was the co-director of the Toronto-based international NetLab Network. His areas of research were community sociology, the Internet, human–computer interaction and social structure, as manifested in social networks in communities and organizations. His overarching interest was in the paradigm shift from group-centered relations to ''networked individualism''. He wrote and co-authored more than 300 articles, chapters, reports and books. Wellman was a professor at the Department of Sociology, University of Toronto, for 46 years, from 1967 to 2013, including a five-year stint as the S. D. Clark Professor.

Harrison White
Harrison Colyar White (March 21, 1930 – May 18, 2024) was an American sociologist who was the Giddings Professor of Sociology at Columbia University. White played an influential role in the “Harvard Revolution” in social networks and the New York School of relational sociology. He is credited with the development of a number of mathematical models of social structure including vacancy chains and blockmodels. He has been a leader of a revolution in sociology that is still in process, using models of social structure that are based on patterns of relations instead of the attributes and attitudes of individuals. Among social network researchers, White is widely respected. For instance, at the 1997 International Network of Social Network Analysis conference, the organizer held a special “White Tie” event, dedicated to White. Social network researcher Emmanuel Lazega refers to him as both “Copernicus and Galileo” because he invented both the vision and the tools. Th ...
