Lecture, LUCIS What's New?! Series

Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

Enforcement of group cooperation fails because of discriminatory punishment, according to research by Welmer Molenmaker and colleagues. When group members have different backgrounds, punishment turns into a double-edged sword: no longer used just to prevent group exploitation, but also to break the…

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

The Educational Sciences programme group of the Institute of Education and Child Studies at Leiden University provides courses in the field of student education and the learning and development of children in the school context.

The illegal use of hand grenades has generated a lot of public interest over the last few years but very little is known about the nature and extent of these incidents. This research project is trying to fill that gap.

On Monday 11 September, Matthew Hoye presented an early draft of a grant proposal on 'Remittance, Paradigms, and Extreme Cases' during a GTGC lunch seminars.

The focus of our theoretical research is understanding the behaviour of soft condensed matter, physical matter which is deformed or structurally altered by thermal fluctuations or small stresses.

The programme group Research Methods and Statistics offers support to researchers from a variety of research projects within Education and Child Studies.

The development of space resource activities is happening now. In the absence of a clear framework to govern these activities, there is a need to examine the concepts that are being discussed in order to ensure that they meet existing treaty obligations regarding on-orbit operations and space resource…

We explore the particle physics and quantum world at the time of the big bang.

This report concerns itself with terrorist technical innovation, particularly with regards to terrorists’ incorporation of emerging technologies into their practices. More specifically, it investigates, through the elaboration of a theoretical learning framework, how terrorist groups can adopt the practices…

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…

Most of current public-key cryptography is considered insecure against attacks from sufficiently powerful quantum computers. Post-quantum cryptography studies methods to secure information resistant against such attacks. One proposal is isogeny-based cryptography, which bases its security on computational…

The widely used pesticide thiacloprid can cause a large-scale decline in freshwater insects. This was discovered by researchers from the Living Lab in Leiden. For three months they counted the flying insects in the 36 ditches of the lab. Their research appeared in PNAS.

It is in the interest of all democracies for young people to learn the value of free debate, even on sensitive and potentially divisive issues like terrorism, argue Thorbjørn Jagland (secretary general of the Council of Europe), Sayeeda Warsi (UK parliamentarian), and Francesco Ragazzi (Institute of…

Within the bachelor's program of Education and Child Studies, we include the minor Kindermishandeling en Verwaarlozing: een levensloopperspectief and several other courses.

Physical chemist Rik Mom developed a revolutionary way to investigate catalysts in action in detail. For this work he received the distinction cum laude during his PhD defence on 29 June.

A professor from Leiden University has subjected various colleagues to intimidating and unacceptable behaviour for a longer period. These are the findings of an investigation carried out by the University’s independent Complaints Committee for Unacceptable Behaviour at the request of the Executive Board…

The aim of this study was to provide insight into how teachers in higher education can be supported in the design, implementation and evaluation of group assignments by developing a theoretical and evidence-based framework for the design of group assignments.

On 1 April 2020, Ivan Romashchenko defended his thesis 'Related Party Transactions and Corporate Groups: When Eastern Europe Meets the West'. The doctoral research was supervised by Prof. S.M. Bartman en Prof. A. Radwan (Kaunas, Lithuania).

In this article, Tokdemir & Klein examine the strategic actions of governments against domestic terrorist groups and domestic terrorist groups’ reactions to such actions.

Why does one person radicalize to involvement in terrorist violence within a group-based context, while another engages in this form of violence alone?

Can SMILE, our multi-component intervention, which combines cognitive-behavioural therapy for insomnia, mindfulness, stress, and lifestyle components, improve sleep quality? Can it also improve mood and quality of life and prevent depression and anxiety in the long term?

How does self-reliance lead to a decrease in collaboration for public goods?

Joseph Callingham from the Leiden Observatory receives the Louise Webster Prize for outstanding post-doctoral research. The prize is awarded by the Astronomical Society of Australia for Callingham’s search for the most extreme object in the Universe.

This study seeks to partially fill the knowledge gap about national culture in Africa, basing its research on data on ethnolinguistic groups (instead of administrative regions).

This article discusses the impact of symbolic gender representation on the willingness of citizens to coproduce.

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?

The Hofstad group is known mainly because of Mohammed B., the murderer of Theo van Gogh. PhD candidate Bart Schuurman examined this Dutch jihadist group based on interviews and confidential police files. How and why did the group come about? What drove some of the group members to commit terrorist…

What drives the restrictiveness of immigration reforms? Political scientists Katharina Natter (Leiden University), Mathias Czaika (Danube University Krems) and Hein de Haas (University of Amsterdam) analysed immigration reforms in 21 Western immigration countries between 1970 and 2012. They found that…

With the rise of information and communication technologies, large amounts of data are being generated and stored in databases. In order to get a better grip on these large amounts of data, serious efforts are being made to discover patterns and relations in the data with the help of new techniques.…

The research in my group addresses a range of topics related to quantum many-body physics.

Streptomyces are filamentous bacteria that produce more than two-thirds of known antibiotics.

Which criteria do ED patients and therapists evaluate as most relevant for recovery? Do patients and therapists differ in their evaluations? Do eating disorder patients differ from a healthy control group in their scores on the Recovery Scale?

Polarisation in our society is on the rise. What makes people increasingly radical? How do we protect ourselves from extremist, terrorist or criminal threats, be they physical or in the cyber world? And what role do intelligence services play in this?
