Fighting for the faith, caring for the sick, and praying for the soul of their benefactors were the main tasks of the military orders, who since the time of the crusades were well represented in the Netherlands in the Middle Ages, including the Frisian lands. Especially the Hospitallers and the Teutonic…

The Division of Systems Pharmacology and Pharmacy (SPP) aims to develop precision medicine approaches to characterize and predict variation in treatment response and enhance translational drug development strategies.

The research area of this division is focused on the development of novel therapeutic modalities and novel concepts in early drug discovery, in order to better predict ligand-target interactions.

The division of BioTherapeutics consists of the former divisions Biopharmaceutics and Drug Delivery Technology.

In the thesis the dynamics of strategies is studied from two perspectives.In the first part of the thesis strategies are considered to be opinions present in a community.

The research group Corporate Governance and Strategy investigates how, with whom and for whom a firm/corporation creates/captures value, in order to inform practice and rule makers about governance issues. By focusing on the dual character of the firm as an entity by itself but also consisting of stakeholders,…

These three repors are part of a research project that assesses how military interventions can best prepare the ground for an effective long-term counter-terrorism policy. Three different cases have been studied, and they have each provided the input for the policy relevant recommendations that are…

On a structural level, the properties featured by a majority of mechanical metamaterials can be ascribed to the finite number of soft internal degrees-of freedom allowing for low-energy deformations.

A story of Two Mosuls, The Resurrection of the Iraqi Armed Forces and the military defeat of ISIS.

Blended and hybrid teaching are presented as crucial in promoting teaching innovation, as well as more flexible study approaches allowing students to develop their own tailor-made study programmes. While the strategy document focuses on the positive aspects of digital teaching tools, no systematic study…

What are key regulators of plant ageing that can reverse ageing in plants (rejuvenation), and how can we use this knowledge to improve crop plants?

What does our faculty stand for and what will we do in the next five years? We are proud to present our new strategic plan that we made together. On this website you will find more information about what our Faculty stands for and what our course is for the coming years

The focus of health care is rapidly changing. The need for maximum gains with minimal input requires tailored health care strategies and an ever more explicit evaluation of health benefits for the patient.

Tuberculosis (TB) is associated with 1.5 million deaths annually. There is a need exists to optimize both current as well as novel antibiotic combination treatment strategies to improve the effectiveness and safety of treatments against TB.

Our previous meta-analysis (Swart et al., 2019) had shown that feedback targeting text comprehension given when students perform a reading task positively influences learning from text. So far, differences in the effects of feedback were explained by design features, such as the timing and richness…
