Hairball Buster: A Graph Triage Method for Viewing and Comparing Graphs

Patrick Allen/ Mark Matties/ Elisha Peterson

Abstract Hairball buster (HB) (also called node-neighbor centrality or NNC) is an approach to graph analytic triage that uses simple calculations and visualization to quickly understand and compare graphs. Rather than displaying highly interconnected graphs as ‘hairballs’ that are difficult to understand, HB provides a simple standard visual representation of a graph and its metrics, combining a monotonically decreasing curve of node metrics with indicators of each node’s neighbors’ metrics. The(..)

Comparing Gender Homophily among the Multilayer Media Social Networks of Face-to-Face, Instant Messenger and Social Networking Services: A Case Study of a High School Classroom

Naoki Maejima

Abstract In which social worlds does gender homophily operate more strongly – offline or online? To address this question, the following two aspects must be considered. First, people currently use many types of online communication media. Second, to examine the homophily effects exclusively, it is necessary to control for other network formation mechanisms such as ‘foci’ and ‘triadic closure.’ For this study, I conducted a mixed-method research in a high school in rural Japan. I asked students a(..)

Commentary: How to do personal network surveys: from name generators to statistical modeling

Isidro Maya-Jariego

Abstract The book “Conducting Personal Network Research” is a conceptual and methodological introduction to the structural study of personal networks. It is part of a series of recent monographs that have begun to systematize the knowledge generated in this area in recent decades (Crossley et al., 2015; McCarty et al., 2019; Perry et al., 2018). In this case, the authors have dedicated a large part of their career to the empirical investigation of the interpersonal relationships, interaction con(..)

Communication networks of an integrated project delivery team for construction: relationships between formal and informal communication networks

Sun Kyong Lee/ Somik Ghosh

Abstract The current study modeled formal and informal communication networks of an integrated project delivery (IPD) team and examined the interplay between the two networks. The IPD format as an alternative method of building construction relies on its multiple stakeholders’ equal and active collaboration. Analyses of both endogenous and exogenous network variables found very distinctive tie formation dynamics between the formal and informal communication networks. While both networks were rat(..)

The ‘GROW Social Network’ datasets

Sabina B. Gesell/ Evan C. Sommer/ Shari l. Barkin

Abstract The GROW Social Network datasets were compiled as part of a 3-year community-based family-based pediatric obesity prevention intervention (N = 610). The datasets include (i) multiplex edges between adult study participants at four timepoints (baseline, 3, 12, and 36 mon), and (ii) multiplex edges within small intervention-only subgroups (30 groups of approximately 10 adult intervention participants) and a previously validated self-report measure of perceived cohesion at three timepoints(..)

COVID-19 Health Communication Networks on Twitter: Identifying Sources, Disseminators, and Brokers

Ian Kim/ Thomas W. Valente

Abstract Coronavirus disease of 2019 (COVID-19)’s devastating effects on the physical and mental health of the public are unlike previous medical crises, in part because of people’s collective access to communication technologies. Unfortunately, a clear understanding of the diffusion of health information on social media is lacking, which has a potentially negative impact on the effectiveness of emergency communication. This study applied social network analysis approaches to examine patterns of(..)

Visualizing Multilevel Networks for the Analysis of Superposed Levels of Collective Agency

Emmanuel Lazega

Abstract This picture, produced by Julien Brailly et al. (2016) and David Schoch (2020), visualizes multilevel networks of individuals and organizations.

Academic Collaboration via Resource Contributions: An Egocentric Dataset

Michał Bojanowski,/ Dominika Czerniawska/ Wojciech Fenrich

Abstract In order to understand scientists’ incentives to form collaborative relations, we have conducted a study looking into academically relevant resources, which scientists contribute into collaborations with others. The data we describe in this paper are an egocentric dataset assembled by coding originally qualitative material. It is 40 multiplex ego networks containing data on individual attributes (such as gender, scientific degree), collaboration ties (including alter–alter ties), and re(..)

Clients’ outcomes from providers’ networks: the role of relational exclusivity and complementary capabilities

Denis Trapido/ Francesca Pallotti/ Alessandro Lomi

Abstract Organizations have leeway in how much they employ their network relations to the benefit of their clients. When do they do so more rather than less? Relying on research on trust and knowledge absorption, the authors suggest that providers’ network relations generate better outcomes for their clients when these relations are concentrated in a limited, exclusive set of partners. The authors argue that providers’ relational exclusivity benefits clients because it facilitates the awareness (..)

The contingent effect of work roles on brokerage in professional organizations

Anssi Smedlund/ Emily W. Choi

Abstract In this paper, we consider whether brokerage in an intra-organizational communication network and type of work role interact to predict individual performance in a professional organization. The independent–interdependent nature of work roles is considered a key factor in structural contingency theory, but is yet to be studied in relation to brokerage. We propose that a brokerage position has a joint effect on performance along with work role in a study of organization-wide communicatio(..)

Embarked on social processes (the rivers) in dynamic and multilevel networks (the boats)

Emmanuel Lazega

Abstract This paper is the written text underlying the keynote presentation at the Sunbelt XXXVIII in Utrecht, 2018. It presents a neo-structural approach to social processes in the organizational society and the usefulness of the analyses of multilevel networks to understand how we navigate these processes and are made aware of them when we face cooperation dilemmas. Empirical illustrations look at how multilevel networks and relational infrastructures are useful to research a process such as c(..)
