Persuasion is at the core of norm creation, emergence of collective action, and solutions to ‘tragedy of the commons’ problems. In this paper, we show that the directionality of friendship ties affect the extent to which individuals can influence the behavior of each other. Moreover, we find that people are typically poor at perceiving the directionality of their friendship ties and that this can significantly limit their ability to engage in cooperative arrangements. This could lead to failures in establishing compatible norms, acting together, finding compromise solutions, and persuading others to act. We then suggest strategies to overcome this limitation by using two topological characteristics of the perceived friendship network. The findings of this paper have significant consequences for designing interventions that seek to harness social influence for collective action.

Calculating different #centrality measures for a street #network takes longer than expected.
#DegreeCentrality is calculated in a few milliseconds. But oh boy. #ClosenessCentrality and #BetweennessCentrality are proper whoppers. For a network of 65 000 nodes, we're talking about 2+ hour calculation times for the closeness centrality, not to mention the betweenness.
Apparently switching to #igraph would provide a speed boost over #networkx but the convenience of #osmnx has won me over.

"Gaining control over a preferential food resource had far-reaching social consequences:
- increase in both #submission & #aggression #centrality
- changes in the socio-demographic characteristics of her agonistic interaction partners
- her #grooming balance shifted in her favour"

Betweenness Centrality in Spatial Networks: Our latest publication is available online at https://doi.org/10.4230/LIPIcs.GIScience.2023.83.
We analysed how #spatial density of nodes influences betweenness #centrality and provide a generic method for mitigating these effects. #SpatialCentrality
Looking forward to presenting and discussing our findings next Wednesday at #GIScience2023 conference.
