Making explicit use of the grid-based structure, model estimation can be carried out efficiently with the R package mgcv, allowing for complex model fits over large sets of areas (e.g. continents). We provide a tutorial how researchers can apply our method for their own work[5/5].

We show how conflict is triggered across cells, over varying distances and time lags. Diffusion is heavily driven by population structures. Conflict generally breaks out in densely populated areas and from there diffuses, disproportionately affecting less populated areas. [4/5]

We develop a generalized additive model that smooths across the spatio-temporal history of each observation, to capture these diffusion effects. Using conflict data from UCDP & PRIO grid cells in Africa, we analyze diffusion up to 550km in distance and 24 months in the past.[3/5]

Armed conflict exhibits substantial diffusion, i.e., spreading, across space and time. However, existing statistical models do not analyze nor fully capture these complex transmission processes. [2/5]

Amazing and really grateful to see our paper on language usage in Ukraine before and during the invasion on that list #UkraineRussiaWar.
Communications Psychology is celebrating its first birthday and has recently reached the publication of its 100th peer-reviewed paper. 🥳 We mark our transition to toddlerhood by reflecting on publications, milestones, and development.

Schon nach der Annexion der Krim wurde Russisch in der Ukraine unpopulärer. Das hat sich seit Beginn des russischen Einmarschs verstärkt.
