Culture, Boundaries and Attitudes: A Meta-Analytic Test of Tie-Strength Theory

Although the strength-of-weak-tie theory is foundational in social network research, studies have reported inconsistent results sometimes supporting the weak tie theory and other times contradicting it. To address these inconsistencies, we explicate three boundaries of weak-tie theory: culture, labor markets, and outcomes. First, the theory was developed and tested extensively in Western nations, raising the issue of whether cultural context affects outcomes. Second, the theory was tested using lower-level applicants finding jobs across organizations, raising the issue as to the applicability of the theory for job movement within organizations for high-ranking employees. Third, beyond the question of finding a job, the question arises as to strength-of-tie effects on a broader set of outcomes such as access to information and job attitudes. Based on a meta-analysis of 101 studies (n = 23,303) we found that strong ties were more potent than weak ties in conformist cultures. Second, strong ties within the organization were more beneficial than weak ties. Also, managers benefitted more from strong ties. Third, strong ties facilitated immediate effectiveness and positive job attitudes whereas weak ties enhanced distal effectiveness for low-end employees.

Escaping Network Gravity: Innovative Team Structures in Video Game Development and Recorded Jazz

The main mechanisms governing social tie formation and operation are at odds with recognizing new ideas. Homophily, closure, skewed degree distributions, and limited vision are four main forces of network gravity. This talk brings cases where these gravity forces were overcome by organizational design and emergent institutions. Using data on more than 100,000 video game developers from the 1980’s to the present, and 400,000 jazz musicians from 1890 to the present I show mechanisms of achieving generative tension, productive diversity, and sustained exploration. I will highlight the role of structural folds, and the significance of overlapping yet cognitively diverse communities.

About Balazs Vedres

Vedres’ research furthers the agenda of understanding historical dynamics in network systems, combining insights from network science, historical sociology, and studies of complex systems in physics and biology. His contribution is to combine historical sensitivities to patterns of processes in time with a network analytic sensitivity to patterns of connectedness cross-sectionally. A key element of this work was the adoption of optimal matching sequence analysis to historical network data. His research results were published in the top journals of sociology, with two recent articles in the American Journal of Sociology exploring the notion of structural folds: creative tensions in intersecting yet cognitively diverse cohesive communities. Vedres’ recent research follows video game developers and jazz musicians as they weave collaborative networks through their projects and recording sessions. Vedres is the recipient of several awards and prizes. He is the founder and director of the Center for Network Science at Central European University.

What Can Congress’s Twitter Use Teach Us About Framing and Polarization?

Social media offers politicians an opportunity to bypass traditional media and directly influence their audience’s opinions and behavior through issue framing. I examine how members of the U.S. Congress use Twitter to accomplish framing and explore the effects of their behavior on mainstream media coverage. Social media also offers researchers trace data for detecting topic communities and political polarization that would otherwise not be revealed until legislative votes take place. I will discuss how my colleagues and I used politicians’ social media behavior, especially the affiliation networks that result from their hashtag use, to create new measures of political polarization that make it possible for us to gauge polarization throughout the legislative process.
