The effects of many treatments are determined, to a significant degree, by factors other than the medicine or treatment itself. For example, placebo effects can be equal to the effect size of for example antidepressants or painkillers. Contributing factors are the trust placed in the doctor, the expectation…

Why does the textural gap between the music that one can improvise and that which one can practice and learn to play (as in completely written-out music) seem to be bigger in the case of the guitar than, for example, in that of keyboard instruments?

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

Quantum hardware comes with a different computing paradigm and new ways to tackle applications. Much effort has to be put into understanding how to leverage this technology to give real-world advantages in areas of interest for industries such as combinatorial optimization or machine learning.

This research project problematizes the applicability of ballet within a contemporary choreographic practice.

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell.

Can bars, gyms and travel providers refuse customers who have no proof of vaccination? And can an employer dismiss employees who are not vaccinated? Reports in the Dutch media about travel organisations and a dance instructor who are refusing customers who have not yet been fully vaccinated have sparked…

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

In the thesis we demonstrated an 85% state transfer efficiency between two mechanical modes coupled to a common optical mode via stimulated Raman adiabatic passage (STIRAP) in the classical regime. We also showed possibilities to manipulate quantum states of the mechanical modes via STIRAP.

A civil servant employed by the municipality of The Hague was cause for discussion after taking part in an Extinction Rebellion protest. Only under additional conditions could the employee in question stay on at the municipality. She decided to resign. According to Barend Barentsen, Professor of Labour…

The United Nations Office for Disarmament Affairs (UNODA) has published the 2017 issue in their Civil Society and Disarmament series, titled Voluntary, Non-Binding Norms for Responsible State Behaviour in the Use of Information and Communications Technology: A Commentary. The series aims to provide…

Research on this theme concerns Europe’s position in global markets, its response to the emergence of new international trade and financial actors that challenge institutions where Europe has long had considerable influence.

Human civilization consumes a huge amount of fossil fuels, which has resulted in an atmospheric CO2 level which has not been higher in over 800 millennia.

The aim of the competition is to prolong the legacy of Professor Benjamin Marius Telders, who became a professor of international law at Leiden University in 1937.

This book expands on the existing literature on the international dimension of democratization by introducing the concept of democracy projection.
