This project explores innovative strategies to counter online extremist content, focusing on integrating traditional content moderation tactics with targeted online interventions. Through research, workshops, and data-driven experiments, we aim to answer: How and when should traditional content moderation…

Having mostly ignored the gains Dutch traders, investors and firms attained from serving the French, English and Iberian empires, debate in the Netherlands now demands a re-evaluation of Dutch colonial responsibilities. By recovering knowledge of these gains, this project will measure the wealth obtained…

Researchers at LED3 are working together with biopharmaceutical company Galapagos to develop software for use in early drug discovery (funded by NWO). This software is able to design molecules with several simultaneously optimized characteristics and will also take prediction reliability into consideration…

The Leiden Slavery Studies Association (LSSA) is dedicated to promoting a greater understanding of slavery and post-slavery in any period and any geographical region.

In this thesis, we extend the concept of null models as canonical ensembles of multi-graphs with given constraints and present new metrics able to characterize real-world layered systems based on their correlation patterns.

This series provides a venue for scholarly work—research monographs and edited volumes—that advances our understanding of the history of slavery and post-slavery in any period and any geographical region. It fills an important gap in academic publishing and builds upon two relatively recent developments…
