Showing papers in "Social Networks in 2019"

TL;DR: There is gender pattern to the networks around male and female entrepreneurs, but the network theory of advantage from access to structural holes similarly predicts the success of male andFemale entrepreneurs regardless of gender.

TL;DR: Different betweenness centrality measures are explored including three inspired by the dual projection approach recently suggested by Everett and Borgatti 2013, which show higher success than classic approaches in identifying the criminal leaders.

TL;DR: Using heterogeneous choice models, it is found that a higher number of connections as well as less clustered ego-networks hindered early abandonment while early adoption was only a secondary factor.

TL;DR: The results from the multilevel ERGM reveal a complex interplay between firm-level activity and international trade patterns and the approach can be extended to other industries to improve understanding of the international organisation of production.

TL;DR: The results suggest that network interventions do not always need to rely on opinion leaders, and under certain conditions, interventions can create opinion leaders by changing local social networks.

TL;DR: It is found that some triadic brokerage structures are more effective than others in closing the communication gap between practitioners and researchers.

TL;DR: It is found that aggregate estimates of parameters associated with mechanisms of theoretical interest mask fine-grained temporal variation in relational events sequences.

TL;DR: Li et al. as mentioned in this paper used a network dynamics model to explain the formation of a small-world network with an elite-clique, in which elites are also the centers of many small groups.

TL;DR: It is shown that estimating the decay parameters improves in-sample performance of the model and that the out-of-sampleperformance of the best model is strong, suggesting that the findings can be generalized to the population of interest.

TL;DR: Practical and ethical challenges to designing and collecting quality network data faced by health services researchers are discussed and high-utility recommendations to address these challenges are developed.

TL;DR: It is found that negative ties travel down status hierarchies and target low status individuals, and a negative tie between two people becomes more likely as their status difference increases, suggesting a low-status rejection mechanism.

TL;DR: This study reinforces previous research showing that team efficiency in the League of Legends professional scene is positively affected by the intensity of their interaction while centralization of resources is detrimental.

TL;DR: The need to conduct more in-depth evaluations of how better creation of social capital and its effects on status attainment could be closely linked to positions of privilege and advantage accumulation processes in highly unequal contexts is discussed.

TL;DR: It is shown that, on top of traditional forms of homophily, MPs' ties to interest groups also make a difference, and MPs with ties to a similar type of interest groups are more likely to co-sponsor their respective proposals.

TL;DR: Even with similar core network size, acquaintanceship volume increases the likelihood of having adequate social support available, suggesting that broader acquaintanceship networks also structure individual outcomes.

TL;DR: This paper estimates 4 models to understand how endogenous and exogenous attributes contribute to the emergence of the TSE production network and shows that the ERGM model fits the real data only when the geographic distance, firm sizes the industrial sector of the firms are considered.

TL;DR: It is shown that combining multistart relocation heuristics with tabu search or variable neighborhood search can rapidly produce partitions of the vertices of signed networks that are competitive with those obtained using existing metaheuristics.

TL;DR: This consideration of global influence in OSNs, beyond neighborhood effects, extends past research that focused mainly on local influence and provides new insights about influence sources in general and viral marketing in particular.

TL;DR: It is argued that the nature of objective dominates the structural characteristics regarding the security-efficiency dilemma, and thus, both illicit drug and PKK affiliated narco-terror networks in Turkish context are driven by material incentives relying more on efficiency and striving to balance organizational security with social characteristics (trust ties).

TL;DR: Researchers are encouraged to further explore the opportunity of implementing ego-centered social network modules in cross-sectional as well as longitudinal self-administered surveys, while being cautious that in longitudinal surveys the chance of panel conditioning effects may increase with the average network size and the response burden of the network module.

TL;DR: Three potentially synergistic and combinable techniques for data collection are proposed for each stage of data collection – biographies for data extraction, graph databases for data storage, and checklists for data reporting.

TL;DR: The effects of informal, triadic network configurations on boundary spanning are contingent on formal organizational design, and a Bayesian approach for exponential random graph models specifically designed for the statistical analysis of interpersonal relationships within and across subgroups or subunits is adopted.

TL;DR: A typology of what social phenomena communities of hyperlinked actors may signify—topical similarities, ideological associations, strategic alliances, and potential user traffic—is developed and recommendations for community detection grounded in these concepts are offered.

TL;DR: A solution that combines identifying tightly bounded intervals with predicting uncertain critical values using node-level information is introduced, which leads to qualitatively different conclusions about the role of peer reinforcement in diffusion.

TL;DR: Investigation of the network dynamics of affiliative ties in Portuguese preschool children using stochastic actor-based models showed that the existence of reciprocal ties decreased preschool children's tendency to create new ties.

TL;DR: The paper concludes that the sequencing of interlocks and cartels is mainly driven by exogenous pressures, and finds no evidence to support that board interlocks constitute sites of cartel formation.

TL;DR: The results confirm that embeddedness promotes trustfulness and trustworthiness and show that endogenously chosen embeddedness promote trustfulness more strongly than exogenously imposed embeddedness, but there is no systematic variation in investments in embeddedness or effects in the size of the trust problem.

TL;DR: The results suggest that interventions are best carried out at the peer-network level, particularly for behaviour vulnerable to complex contagion, such as smoking and cannabis use.

TL;DR: It is shown that while privately funded cluster organizations have fewer formal partnerships, their managers more actively collaborate at the informal level, and tendencies towards funding-based homophily and cross-level closure at both levels, formal and informal.

TL;DR: Findings provide evidence that health decisions are shaped by individual resources as well as social capital available through network ties, offering a unique perspective of the ways that social networks contribute to producing, and potentially reproducing, unequal health.
