Abstract
Ample theoretical work on social networks is explicitly or implicitly concerned with the role of interpersonal interaction. However, empirical studies to date mostly focus on the analysis of stable relations. This article introduces Dynamic Network Actor Models (DyNAMs) for the study of directed, interpersonal interaction through time. The presented model addresses three important aspects of interpersonal interaction. First, interactions unfold in a larger social context and depend on complex structures in social systems. Second, interactions emanate from individuals and are based on personal preferences, restricted by the available interaction opportunities. Third, sequences of interactions develop dynamically, and the timing of interactions relative to one another contains useful information. We refer to these aspects as the network nature, the actor-oriented nature, and the dynamic nature of social interaction. A case study compares the DyNAM framework to the relational event model, a widely used statistical method for the study of social interaction data.
Highlights
Ample theoretical work on social networks is explicitly or implicitly concerned with the role of interpersonal interaction
We propose that the empirical study of interpersonal interactions can offer insights that go beyond the study of stable relationships and can complement our understanding of social network evolution and processes
Do we present results of the Dynamic Network Actor Models (DyNAMs) but we compare those to the relational event model (Butts 2008), in which rightcensored intervals are taken into account
Summary
Ample theoretical work on social networks is explicitly or implicitly concerned with the role of interpersonal interaction. In the course of this article, the actor-oriented nature of the DyNAM is theoretically and empirically compared to the most widely used, tie-oriented method for the analysis of time-stamped network data, the Relational Event Model (REM) (Butts 2008).
