L1-oral language education is widely regarded as essential for developing communicative competence and critical thinking. However, as a research domain it remains relatively underexplored. The aim of this study was to identify effective elements and challenges within oral language education and to contribute…

We know that armed conflict breeds conflict. We also know the political, economic and demographic factors that inform this repetition of conflict. But we do not understand why accumulated conflict risk factors sometimes do and other times do not pay out in more violence. What if we go beyond macro structural…

Uniting an international consortium of scholars, the Skandapurāṇa Project comprises a team of researchers working in fields across the Humanities. We are creating a critical edition of a foundational work of purāṇic literature and, in doing so, tracing the dynamics of a textual tradition to better understand…

Andrea Evers has received an NWO research talent grant with Jelle van Leusden as the PhD candidate. This grant enables them to start a research project to examine whether automatically regulated responses, such as the circadian rhythm, can be conditioned during sleep.

When did the Mali Empire disintegrate? What does the Sunjata heritage demonstrate about the political situation after 1600?

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

What are the circadian disturbances underlying depression vulnerability? How are they related to mood, cognition and sleep ?

Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

Pancreatic ductal adenocarcinoma (PDAC) is the deadliest common cancer, with only 8% of patients surviving for five years. One reason for this poor outcome is that current chemotherapy treatments are highly toxic, often leaving patients too sick to receive treatment or forcing doctors to lower the dose…

For our students, studying in The Hague can make a big difference. The Hague is proud to be known as the international city of peace and justice. The city is full of opportunity and is a fantastic student city.

A liveable planet. More biodiversity. And resources which are being managed wisely. At the CML, we want to make an impact with our research and education. On this website you can read what we do to achieve that.

We aim to understand ion homeostasis in the model eukaryote S. cerevisiae.

What are the critical elements in sonic materialization of fixed media electroacoustic music and how can these parameters be classified? How would interpretation be defined in performing fixed media music? What are the creative and new ways of presenting fixed media music by incorporating all the presentation…

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

If a new method has been developed to recognize and treat a (neuro-)psychological disorder or related behavioral factors, it cannot yet be used directly in clinical practice. First, the method should be evaluated, preferably in randomized controlled trials.

Actinobacteria are Gram-positive bacteria that have a complex multicellular life cycle and are well known for their ability to produce a wide range of bioactive natural products (NPs).

How can sustainable and circular decision-making be integrated into manufacturing operations? How can data from physical simulation models, digital twins and operations be used for sustainability assessment? How can manufacturing decisions affecting sustainability and circularity be integrated into…

The more we learn about a (neuro-)psychological or physical disorder and the related behavioral factors, the better we can not only identify them, but also treat them. It is therefore important that recent insights about (neuro-)psychological problems and related behavioral factors are incorporated…

The research described in this thesis focused on identifying novel drug targets and synergistic combinations for triple-negative breast cancer (TNBC), a virulent subtype of breast cancer with a dismal prognosis and limited therapeutic options.
