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.

Statistical Power to Detect Social Network Effects in Small Groups
One handy method for modeling social network contagion effects (i.e., using peer attributes to predict the focal actors’ attributes) is the spatial lag or spatial autocorrelation model. Wang, Neuman, and Newman (2014) demonstrated that in order to attain adequate statistical power to detect such social network effects, networks researchers will often need data from a modest-sized network of 40 or more persons. This poses a problem when one’s theoretical focus is on social contagion/network effects in small groups and teams, for which the membership is often much smaller than N = 40. Using simulation methods, I seek to extend the work of Wang et al. (2014) to investigate how many groups/teams are needed in order to reliably detect social network contagion in small group

About Dr. Newman
Daniel A. Newman, Ph.D., is an Associate Professor in the Department of Psychology and the School of Labor & Employment Relations at the University of Illinois at Urbana-Champaign. His research deals with race and gender diversity in HR management (i.e., adverse impact, hiring/minority recruiting), emotional intelligence (what it is and why it relates to job performance), narcissism (why it relates to leadership, counterproductive work behavior, and gender), and research methods (missing data, multilevel approaches, Bayesian meta-analysis). He has been elected Chair of the Research Methods Division of the Academy of Management, and his work has been recognized with the Academy of Management HR Division’s Scholarly Achievement Award, SIOP’s William A.

How Much Do We Know about Knowledge-creating Networks? 

The early excitement of network analysis has given way to a long slog towards testing the meaning of network structures. Software allows us to picture network typology, but we do not yet know how to read the typology in relationship to the value being created. Knowledge-creating networks often involve informal groupings that self-organize into teams. Various data allow us to measure network structures. However, a gap exists between the ability to draw and measure networks on one hand, and the ability to interpret the network data in terms of the value of the structure to participants and beneficiaries. To gain insight into the relationship between the whole network typology and the individual role within the network, testable hypotheses need refinement, and more detailed studies are needed. This talk benchmarks where we are now in our understanding of team networks, and outlines the challenges faced by those of us who study networks, teams, and communication dynamics to outline the research questions we face as we move into the next phases of research.

Accurately Mining Collaboration Interactions in Wikipedia to Detect Systematic Social Mechanisms

Several studies have described systematically occurring interaction patterns, or “social mechanisms”, between editors in collaborative writing of Wikipedia articles. These include ownership behavior, editor camps, newcomer rejection and others. Yet, only few of them have been adequately modeled to detect them methodically. The research that will be presented aims to provide such a model, especially finding suited metrics to describe potentially harmful social mechanisms and to understand them better.

The main challenges that arise in this context are (i) to comprehensively and accurately mine data about the underlying editor to editor interactions occurring in an article (i.e., who exactly collaborates with or antagonizes whom?) and (ii) to represent these interactions in an appropriate model capturing all relevant intricacies over time, e.g., a social graph structure; and (iii) based on this, to find correlations of emerging patterns with the appearance of explicit indicators for these mechanisms.

The talk will cover how we already collected relevant social mechanisms from the literature and successfully tackled the data mining challenge, providing novel raw data to infer editor relationships. It will then outline our current work on modeling editor interactions and plans how to detect the suspected mechanisms in the data.
