This thesis investigates how the assessment of circular economy (CE) at the macro-economic level can be facilitated and promoted⁠.

Increasingly, primary sources from the period before the emergence of digital media are being digitized. These “digital surrogates” have facilitated the work of (historical) researchers; instead of having to visit several archives, libraries and other places, the (primary) sources appear in front of…

PathOS aims to contribute to a better understanding and measurement of Open Science impacts and their causal mechanisms. This is pivotal in order to develop effective OS policy in the EU (European Union). It will do so by collecting concrete evidence of OS effects, by studying the pathways of OS practices,…

Bones contain information about people’s lives such as where they came from, their age at death and which diseases they suffered from. Researchers can deduce a lot from them about a person’s life and about human evolution. This generates leads that could help solve present-day problems, such as how…

Due to the fact that the Frisian lands lacked major political centers in the Middle Ages and also because most of its monasteries suffered complete destruction in the second half of the 16th century, relatively few written documents concerning medieval Frisian history have survived.
