In the shadow of silence
Modeling the “who” and “how” of social influence in the adoption of health practices
Network patterns of university-industry collaboration
University–industry (U–I) collaboration takes on many forms, from research services, teaching and training, to curiosity-led research. In the chemical industries, academic chemists generate new knowledge, address novel problems faced by industry, and train the future workforce in cutting-edge methods. In this study, we examine the dynamic structures of collaborative research contracts and grants between academic and industry partners over a 5-yea…
Multilevel network interventions
Analysing networks of networks
We consider data with multiple observations or reports on a network in the case when these networks themselves are connected through some form of network ties. We could take the example of a cognitive social structure where there is another type of tie connecting the actors that provide the reports; or the study of interpersonal spillover effects from one cultural domain to another facilitated by the social ties. Another example is when the indiv…
Network formation in organizational settings
Circular specifications and “predicting” with information from the future
We review the empirical comparison of Stochastic Actor-oriented Models (SAOMs) and Temporal Exponential Random Graph Models (TERGMs) by Leifeld & Cranmer in this journal [Network Science 7(1):20–51, 2019]. When specifying their TERGM, they use exogenous nodal attributes calculated from the outcome networks’ observed degrees instead of endogenous ERGM equivalents of structural effects as used in the SAOM. This turns the modeled endogeneity into ci…

Trust, quality, and the network collection experience
Data collection in social network research has advanced to include online questionnaires, digital metadata mining of internet sites, and the use of remote-sensing technologies. Some scholars however call for more attention to nuanced understandings of ties and contexts in studies of social structure and relationships, evoking practices that characterise the field's foundational works. This article's two studies reference these earlier efforts, dr…

Multilevel determinants of collaboration between organised criminal groups
International Students' Cross-Cultural Adjustment
International education provides students with an opportunity to develop new social networks while they fit in to the new culture. In a three-wave longitudinal study, we investigated how social networks and psychological adjustment coevolve within a group of international students enrolled in a coursework degree at the tertiary level. Using the Stochastic Actor-Oriented Model (SAOM), we identified the occurrences of social selection based on the …
Illicit Network Dynamics
Brokering between (not so) overt and (not so) covert networks in conflict zones
There is a tendency to consider covert networks as separate from overt networks. Drawing on data from the Democratic Republic of the Congo, we demonstrate that this is not the case and identify how covert and overt networks are mutually constitutive. While most studies of African brokers have relied on network metaphors like 'Big Men' and 'social membranes', we consider the embeddedness of 'covert' networks in 'overt' networks explicitly. We perf…
Measuring knowledge and experience in two mode temporal networks
Residential Segregation and 'Ethnic Flight' vs. 'Ethnic Avoidance' in Sweden
Residential segregation along ethnic categories has been associated with social disadvantages of minority group members. It is considered a driving factor in the reproduction of social inequalities and a pressing issue in many societies. While most research focuses on neighbourhood segregation in the United States, less is known about the origins of ethnic enclaves in European cities. We use complete data of residential moves within Stockholm mun…

Snowball sampling for estimating exponential random graph models for large networks
Temporal dynamics in covert networks
Criminal organisations tend to be structured as a network in order to optimise flows of resource exchanges. The consolidation of these structures strengthens the criminal organisation’s capability of becoming more and more efficient over time. Recently, researchers in the field of covert networks have begun to analyse the dynamics of these networks. Thus far, the models and methods used to analyse the temporal dynamics of covert networks have com…
Multilevel embeddedness
Simultaneous modeling of initial conditions and time heterogeneity in dynamic networks
In dynamic networks, the presence of ties are subject both to endogenous network dependencies and spatial dependencies. Current statistical models for change over time are typically defined relative to some initial condition, thus skirting the issue of where the first network came from. Additionally, while these longitudinal network models may explain the dynamics of change in the network over time, they do not explain the change in those dynamic…
