THE CO-EVOLUTION OF INSTRUMENTAL AND AFFECTIVE CONTENT IN INTRAORGANIZATIONAL TASK-RELATED NETWORKS: A THEORY OF AFFECTIVE PRIMACY
Tiziana Casciaro, University of Toronto
Abstract
To better understand the structuration of task-related networks in organizations, we develop a theory of the co-evolution of instrumental and affective content in task-related ties. We test this theory with longitudinal whole-network data from employees in a small functional-form organization, which we analyze with a methodology drawing from the social relations model of interpersonal perception and hierarchical Bayesian models for social network analysis. We find that the affective content of social relations stimulates the formation of task-related ties both directly, by increasing the hedonic rewards from the interaction, and indirectly, by altering the instrumental value of the relationship. Conversely, the instrumental value of the interaction does not modify its affective value either directly or indirectly. Similarly, formal-structural arrangements shape the instrumental content of the interaction but do not alter its affective content. The only robust predictor of affective content in our data is attribute similarity among social actors. We conclude that, while both instrumental and affective motivations trigger the formation of task networks, the affective content of task-related ties is primal: it causes task-related action and related instrumental rewards, but is independent of formal-structural and instrumental dimensions of social interaction.

Martin Everett to speak on core/periphery structures in 2-mode networks
LINKS Center Colloquium
Friday, June 19th at 11am in B&E 446
Martin Everett has a master degree in mathematics and completed a doctorate on social networks at Oxford University under Clyde Mitchell, one of the pioneers of the subject. He has been an active in social network research for over thirty years and has published over 100 articles mainly on social networks. In 1987 during a sabbatical at the University of California Irvine he teamed up with Steve Borgatti. They have collaborated ever since researching and publishing on methods for social networks, teaching workshops and producing the software program UCINET. Martin has been the president of INSNA the international professional body for social network analysis and still serves on the board; in 2001 he was awarded the Simmel award from the society, the highest award available.

Network Analysis in the Social Sciences
Over the past decade, there has been an explosion of interest in network research across the physical and social sciences. For social scientists, the theory of networks has been a gold mine, yielding explanations for social phenomena in a wide variety of disciplines from psychology to economics. Here, we review the kinds of things that social scientists have tried to explain using social network analysis and provide a nutshell description of the basic assumptions, goals, and explanatory mechanisms prevalent in the field. We hope to contribute to a dialogueamong researchers from across the physical and social sciences who share a common interest in understanding the antecedents and consequences of network phenomena.
