Bestuurlijke Aandacht tijdens Politieke Turbulentie
Besluitvormers in de publieke sector opereren te midden van een overvloed aan informatie en onduidelijke politieke doelstellingen. Aandacht is de sine qua non van beleidsvorming: waar aandacht voor is kan geadresseerd worden in beleidsoplossingen; wat over het hoofd gezien wordt niet. Ondanks het belang…

Amerikaans buitenlands beleid en liberalisme
The NWO-funded Vidi project “American foreign policy and liberalism” challenges the idea that the United States has created and sustained a “liberal international order” since World War II. It instead explores the ways in which illiberal ideologies – such as those underpinning racial hierarchy at home…

The optimization and scale-up of the electrochemical reduction of CO₂ to formate
Carbon dioxide capture and utilization technologies are necessary to create a truly circular economy. The electrochemical reduction of carbon dioxide to formate is an appealing carbon utilization method as it can be performed at room temperature and pressure, it only requires two electrons, and it has…

Light Weighed: On the Statistics and Systematics of Weak Gravitational Lensing
In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Who gets what, when, and how? An analysis of stakeholder interests and conflicts in and around Big Science
Big Science, commonly defined as conventional science made big in three dimensions, namely organizations, machines, and politics, brings a plethora of different stakeholders together, often for a long period of time. This includes policymakers, scientists, (scientific) managers as well as local “host”…
