The effect of co-location on human communication networks

The ability to rewire ties in communication networks is vital for large-scale human cooperation and the spread of new ideas. We show that lack of researcher co-location during the COVID-19 lockdown caused the loss of more than 4,800 weak ties—ties between distant parts of the social system that enable the flow of novel information—over 18 months in the email network of a large North American university. Furthermore, we find that the reintroduction of partial co-location through a hybrid work mode led to a partial regeneration of weak ties. We quantify the effect of co-location in forming ties through a model based on physical proximity, which is able to reproduce all empirical observations. Results indicate that employees who are not co-located are less likely to form ties, weakening the spread of information in the workplace. Such findings could contribute to a better understanding of the spatiotemporal dynamics of human communication networks and help organizations that are moving towards the implementation of hybrid work policies to evaluate the minimum amount of in-person interaction necessary for a productive work environment. © 2022, The Author(s), under exclusive licence to Springer Nature America, Inc.

Virtual and in-person co-design workshops: From alternative to complementary approaches

Co-design methods and toolkits are commonly used to involve people from diverse backgrounds and disciplines in design processes, promoting collaboration, design thinking, shared decision making, and creativity. These methods and toolkits are generally tailored to in-person workshops supported by different physical artifacts (e.g. card-sets) in a shared physical location. Physical co-location and artifacts allow participants to interact in seamless ways, relying on everyday modalities of interaction. The CoViD-19 pandemic has forced many of such workshops online. This required transforming location, methods, toolkits and to rethink interaction among participants. With this workshop we aim to look back at these experiences of transformation and to reflect on the affordances of the physical and the virtual in co-design workshops. What are the challenges of transforming location, methods, and toolkits that are designed for in-person workshops into the digital? In which ways can in-person and virtual workshops co-exist and complement each other? We invite participants to share their experiences and reflect on how to bring together virtual and in-person co-design workshops. © 2022 Owner/Author.
