People are less willing to give up an interest when in a negotiation situation than when they can do it of their own free will, as Leiden University psychologist Eric van Dijk discovered. Knowledge of this kind can be used by policy makers, for instance, to motivate people to adopt certain desirable…

Industrialised countries extract natural resources in the territories of indigenous peoples, and appropriate the knowledge and culture of these peoples. Leiden anthropologists work to protect the rights of indigenous peoples. Their knowledge and advice enable governments to source sustainable produc…

The Dutch legal system perhaps appears at first sight not to be very suited for strategic litigation by interest groups. But judgments such as SyRI and Urgenda show that when an interest group does fulfil all the conditions, anything can happen in court.

The ECPR summer school on Interest Group Politics is celebrating its 10th anniversary. To celebrate this especial edition, this year’s summer school includes many renowned researchers and professors from around the world. In addition, as a part of the celebration, we are organizing an exceptional one-day…

In April 2018, Melanie Fink was elected as a member of the Coordinating Committee of the ESIL Interest Group ‘The EU as a Global Actor’. For the next four years, she will work in that function alongside Christine Kaddous (University of Geneva), Anne Thies (University of Reading), and Ramses Wessel (University…

On Wednesday 6 September 2017 the Interest Group on Migration and Refugee Law of the European Society of International Law (ESIL/SEDI) hosted a workshop in Naples, Italy, in cooperation with the ILS 2.0 Project.

How interest groups, differences in policy issues and institutional differences between countries affect whether public opinion is translated into policy?

Where did the new generation of antislavery activists get their inspiration to organize in large-scale pressure groups?

If a society is to be secure, sustainable and resilient, conflicting interests must be reconciled. Researchers at Leiden University study the behaviour of individuals, groups and states in relation to this issue, and use their knowledge to promote equality within and between communities.

The unit residue group, to which the present thesis is devoted, is defined using the norm-residue symbol, which Hilbert introduced into algebraic number theory in 1897.

What legislative and regulatory questions arise when children, adolescents or elderly people use the Internet?

We are interested in understanding the mechanics of soft materials, of which biological materials are prominent examples.

Healthy University Leiden consists of a taskforce, focus group and seminars.

How did free agents cooperate with the VOC and the WIC, through lobbying for private interests within the Companies as well as at the highest political levels?

Learning is easiest out of interest. But interest is often multiple, and expands in various directions. How do you organize education accordingly?

The focus of our theoretical physics research is the nature of macroscopic matter that is in one or the other way still in the grip of quantum physics.

Weekly Friday morning BPOC/SSNMR group meetings.

The purpose of eLaw's Working Groups is to stimulate a productive working environment for cooperation within the Center for Law and Digital Technologies at Leiden University.

Every LACDR PhD candidate has access to the SharePoint teamsite of the LACDR PhD group. This site is specially and only for PhD candidates of the LACDR. We strive to collect here all relevant PhD information and to stimulate the collaboration and communication in the LACDR PhD community.

The LOFAR e-infrastructure group is responsible for deploying and maintaining LOFAR processing on distributed e-infrastructure. A co-operation between SURFsara, Leiden University and ASTRON, the group develops software to integrate the LOFAR stack with processing pipelines. Our software can schedule…

The Computer Support group provides dedicated support for the computing infrastructure of Leiden Observatory

Researchers at Leiden study group behaviour. One of their findings is that when people make sacrifices for another member of their group, it is probably instinctive. Insights of this kind enable us to better understand and influence the social processes in a neighbourhood or company.

Various sounding board groups give their opinion about the course of the programme. Their vision is important, since they already have knowledge about and experience in (innovation in) education. Some of these sounding board groups are also collaboration partners within the University at the same ti…

In my research, we developed a method to distinguish knots. A knot is a mathematical depiction of the everyday knot that occurs in ropes and cords.

We examine the effect of social learning on emotional competence in children and adolescents with a typical or atypical development.

Boyarsky is on a quest to unravel the nature of one of the most mysterious phenomena in the Universe. The cosmos appears to consist for the larger part out of mass we cannot see. We have no idea where it comes from. Physicists call this ‘dark matter’. Sterile neutrinos are candidate building blocks…

Our world is shrinking, or at least our electronic devices are. From PCs to mobile phones: everything is smaller and thinner. The smaller the chip, the better it can conduct electricity and pass on information.

Leiden University has a rich history in the domain of Papyrology. Papyrology+, founded in 2014, is a collaboration of Leiden scholars studying (Abnormal) Hieratic, Demotic, Aramaic, Greek, Latin, Coptic, and Arabic papyri from a socio-historical, economic and linguistic perspective.

The extensive use of electronic communication channels and other devices has opened new possibilities for collecting data on human behavior. This information is sometimes openly accessible, but largely part of administrative registration systems that are not open to the broader public. The data provides…

In this thesis we classify the pairs (p,G), where p is a prime number and G is a finite p-group possessing an intense automorphism, i.e. an automorphism that sends each subgroup of G to a G-conjugate, that is non-trivial and whose order is coprime to p.

Collaboration is increasingly common among teachers in schools. As such, teacher education should prepare prospective teachers to effectively interact with other teachers in different types of communities or groups.

How do students’ interests develop over time and which interests are subsequently pursued in the higher educational choice of students?

The thesis focuses on synthesis strategies in oligosaccharide campaigns, and the influence of protecting groups.

Our research primarily focuses on the early universe and its origins in theories that go beyond the Standard Model of particle physics.

The research group ‘Quantum and Society’ explores the boundary between quantum technology and science communication.

How are interests embedded and experienced in daily life and to what extent can their origin and development be understood in terms of this contextualization?

We are cosmologists, in other words we use physics to study the Universe, how it started and evolved into the structure that we observe around us.
