Showing papers in "Social Networks in 1979"

TL;DR: In this paper, three competing hypotheses about structural centrality are explored by means of a replication of the early MIT experiments on communication structure and group problem-solving, and it is shown that although two of the three kinds of measures of centrality have a demonstrable effect on individual responses and group processes, the classic measure of the centrality based on distance is unrelated to any experimental variable, the positive results provided by distance-based centrality in earlier experiments is an artifact of the particular structures chosen for experimentation.

TL;DR: This article examined whether clique-structure in cognitive data (i.e. recall of who one talks to) may be used as a proxy for clique structure in behavioral data (e.g., who one actually talks to).

TL;DR: In this paper, a comparison of the triadic-level structure inherent in behavioral and cognitive social network data taken on the same group, using a variety of groups whose communication could easily be monitored, is provided.

TL;DR: In a probabilistic approach to the use of networks as structural models, the point of departure is a randomly constructed network, characterized only by a parameter, here the average outdegree of a digraph.

TL;DR: In this paper, a study of the internal politics of an office demonstrates that levelling coalitions derive from established networks and that the success or failure of the coalition is dependent upon the relationships held and manipulated by the target.

TL;DR: In this paper, the evolution of the structure of a social group through time is described and procedures employed to do this are based on algebraic topological notions and this structural language is shown flexible enough to describe structural change.

TL;DR: In this article, the q-analysis is used to define and operationalise intuitive notions of structure in a soccer match between Liverpool and Manchester United, where the injection of q-holes or obtrusive objects, by the defense of one team appears to contribute to the fragmentation and loss of the other.

TL;DR: This paper contributes to a developed theory of social networks by elaborating one basic proposition: that social connections attract each other as a regular function of network parameters such as ‘structural strength’ (number of common links) and “distance” (length of minimal path of linkage).

TL;DR: In this article, the structural effect of reciprocity on arc changes in friendship networks has been investigated using stochastic models for dyadic interaction and continuous-time Markov chains.

TL;DR: An index of goodness-of-fit for α-fit blockmodels is proposed, based on the purity of the submatrices of the data matrix(es) after the blockmodel partition is imposed, which is compared with those of correlation coefficient.

TL;DR: In this article, the authors introduce a stochastic signed graph and investigate the properties of some indices of balance involving triads, and consider the balance properties of a graph which is randomly signed and of one which has been randomly sampled from a large population graph.

TL;DR: This contribution is an attempt toward investigation of the possibility of a theory of the effects of network properties on social action, and predictions about the structure of the resulting social networks, type of social control and type of exchange taking place within them are made.

TL;DR: In this paper, a Galois connection between the set of relations on the social relations themselves and the lattice of congruences on the universal semigroup is applied to the evolution of kinship systems.

TL;DR: SONET-I is a preliminary but completely operational version of a package of computer programs for the analysis of social structure that can be seen as a graph theoretic formalization and generalization of kinship-based methods of social analysis often associated with British social anthropology.

TL;DR: In this paper, the strength of a point in a graph is defined as the increase in the number of connected components in the graph upon removal of the point, and an algorithm for computing S is presented.

TL;DR: This paper found that socio-economic status homophily was not a prime criterion in students' friendship and dating choices, whereas Hollingshead's 1942 study of Elmtown High found socioeconomic statushomophily to be the prime criterion for students' choice of friends.

TL;DR: In this article, the authors describe the design and implementation of a "pre-structured multi-purpose data base" for information about the Canadian corporate structure, which includes data on directorship, officcrship, executive board membership, and ownership ties among approximately 10,000 Canadian and other financial and industrial corporations and about 6,000 organizations (law firms, brokerage houses, public institutions, etc.) with which directors resident in Canada were affiliated.

TL;DR: In this paper, a balance theoretical approach to the phenomenon of response bias in survey research is developed, which yields a model of the survey interview, specifying the effects of a great number of interview variables.
