As museums face more scrutiny and are being demanded to decolonize, there are opportunities for Dominican museums to adopt a critical perspective and turn their collections and exhibitions into connections to our cultural past, present, and future.

Why do historians so often talk about objectivity, empathy, and fair-mindedness? What roles do such personal qualities play in historical studies? And why does it make sense to call them virtues rather than skills or habits?

Prematurely born neonates require, amongst others, pharmaceutical therapy. Dosing guidelines for these therapies are often based on data from term born neonates or older infants, while these are not necessarily similar to prematurely born neonates.

What is the impact of Indonesia’s democratization process on everyday state-citizen relations?
