Network Dynamics and Field Evolution: The Growth of Interorganizational Collaboration in the Life Sciences1
A recursive analysis of network and institutional evolution is offered to account for the decentralized structure of the commercial field of the life sciences. Four alternative logics of
Standard Cross-Cultural Sample
The Standard Cross-Cultural Sample contains the best-described society in each of 186 cultural provinces of the world, chosen so that cultural independence of each unit in terms of historical origin
Structural cohesion and embeddedness: A hierarchical concept of social groups
While questions about social cohesion lie at the core of our discipline, no clear definition of cohesion exists. We present a definition of structural cohesion based on network connectivity that
Centrality in valued graphs: A measure of betweenness based on network flow
A new measure of centrality, C,, is introduced. It is based on the concept of network flows. While conceptually similar to Freeman’s original measure, Ca, the new measure differs from the original in
Structure and Dynamics of the Global Economy: Network Analysis of International Trade 1965–1980
Structure and Dynamics of the Global Economy: Network Analysis of International Trade Author(s): David A. Smith and Douglas R. White Source: Social Forces, Vol. 70, No. 4 (Jun., 1992), pp. 857-893
Economic Networks: The New Challenges
An approach that stresses the systemic complexity of economic networks and that can be used to revise and extend established paradigms in economic theory will facilitate the design of policies that reduce conflicts between individual interests and global efficiency, as well as reduce the risk of global failure by making economic networks more robust.
Graph and Semigroup Homomorphisms on Networks of Relations
The algebraic definitions presented here are motivated by our search for an adequate formalization of the concepts of social roles as regularities in social network patterns. The theorems represent
Causes of polygyny: ecology economy kinship and warfare.
We discuss and test competing explanations for polygyny based on household economics, malecentered kin groups, warfare, and environmental characteristics. Data consist of codes for 142 societies from
The cohesiveness of blocks in social networks: Node connectivity and conditional density
This study shows several ways that formal graph theoretic statements map patterns of network ties into substantive hypotheses about social cohesion. If network cohesion is enhanced by multiple
Rethinking Polygyny: Co-Wives, Codes, and Cultural Systems [and Comments and Reply]
A new set of codes is offered to begin to unpack the dimensions of polygyny. Included are measures of frequency and statistical distributions of multiple wives, cultural rules, residential
