Some dynamics of social balance processes
Utility and dynamic social networks
Actors and networks as objects
Assessing hierarchy and balance in dynamic network models
This paper discusses two algorithms that compute important structural properties of dynamic social networks. The properties are hierarchy in a directed graph, and balance at a node in a signed directed graph. The hierarchy algorithm is used in a model that generates dominance structures in groups. The balance algorithm is part of a model that generates deviant behavior in a group. Both algorithms work with a dynamic network data structure that ch…
The emergence of computational sociology
The world of science has undergone a major transformation by virtue of technological innovations in computing and information proessing. Sociology is one site in which this change is being played out. Our basic aim is to set out a revised image of any modern science, within which we can conceptualize and discuss the role of a newly emergent subfield we term computational sociology. Specifically, we expand the familiar two‐component model of a sci…

Scientific Influence
Researchers in scientific specialties and invisible colleges tend to cite each other in their written communications and especially in the Journals devoted to those specialities Such citations form a network through which there are many influence paths The main paths through such citation networks contain the key intellectual developments in these scientific fields If a specialty hangs together as a coherent field of research, one would expect th…

Analyzing the Structure of the Centrality-Productivity Literature Created Between 1948 and 1979
Science grows and cumulates on the research fronts of disciplinary specialties, implying that the most fruitful citation analyses will be those looking at well-defined specialties or subspecial ties. The entire literature on centrality and productivity from 1948 to 1979 is used to construct a citation network. Methods are proposed for the analysis of the connective structure of such networks and then applied to the centrality-productivity citatio…
Organizational structures and network processes
This paper explores how organizational structures might evolve out of network processes. A computer simulation model is used to examine how attributes of organization members might influence the flow of work tasks through an organization. This flow of work tasks is modeled as a network, and the properties of this network are analyzed to describe organization structure

Estimating Differential Equation Models On Time Series
This paper explores the statistical properties of estimates proposed by Doreian and Hummon (1976) for systems of simultaneous differential equation systems. Since these procedures are iterative and computationally burdensome, alternative simpler methods are also explored via Monte Carlo Simulations. The simpler methods provide reasonably good diagnostics as to whether or not the more com plicated procedures are worthwhile. Problems of autocorrela…

A Structural Control Model of Organizational Change
This paper presents a differential equation model of organizational change which focuses upon the mechanisms of change. The model is obtained from positing the notion of structural control. The necessary procedures for estimating the model are developed and applied to data from a panel study of bureaucracies. The model addresses Blau's formal theory of differentiation and both modifies and extends that theory. The relationship between size variab…

levels. If the logarithms of S and X are highly correlated-that is, if their ratio is nearly constant-the number of hierarchial levels is almost invariant, so the coefficient of path (b) is quite small. Indeed, Blau's data indicate that this is the case. From the outset, we have taken, as given, a substantial association between S and X; furthermore, Blau notes that the number of hierarchial levels in headquarters offices varies only between 3 an…
