Loopholes in international tax legislation contribute to the misuse of tax rules by multinationals. Leiden University legal experts investigate how the complex national and international tax rules can be made more consistent in order to create a better tax system.

How do tax treaties have to be explained and implemented, and what role does the supranational regulatory process play in this? Which objectives are meant to be used in establishing tax regulations and to what extent are such legislative practices undertaken in a goal-oriented manner?.

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.

A neuro-ecological perspective on adolescent prosocial development

If you replace the standard hydrogen atoms in ice with a heavier variant, something odd happens. The volume occupied by the molecules increases by 0.1 per cent. Leiden chemist Jörg Meyer and his colleagues have created a theoretical model that describes this behaviour. Their research appeared on the…

The Dutch Research Council (NWO) has awarded 400.000 euros in funding to Lotte van Dillen, associate professor at the unit of Social, Economic and Organizational Psychology. With this grant, Lotte van Dillen will investigate how daily distractions influence our dietary consumption habits and glucose…

Leiden Law Cast is a podcast made by Leiden Law School, Leiden University, for everyone who wants to learn more about current legal issues.

Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process. Biophysicists from Delft University of Technology and Leiden University developed a technique that speeds up screening…

Prof. Sarah de Rijcke will succeed Paul Wouters as dean of Leiden University's Faculty of Social and Behavioural Sciences (FSW) from 1 January 2024. Paul Wouters will retire at the beginning of January.

What is the best living environment for dementia patients? To answer this question, Daniela Gawehns is using data mining methods to search through different types of data source. Her research is inadvertently building a bridge between two disciplines that are sometimes somewhat wary of each other.

For the first time, a group of international and interdisciplinary researchers led by Karline Janmaat and her former MSc Student Chirag Chittar, have tested the several hypotheses on music simultaneously in a modern foraging society during their daily search for tubers – their staple food.

Building a fire involves many variables, such as size, choice of fuel, temperature, and burn time, that affect the way the generated heat can be used, and therefore the potential function of a fire. A group of Leiden archaeologists are, together with a team of international colleagues, investigating…

We are all aware of the importance of a healthy lifestyle. However, at the same time we also experience many difficulties when we are trying to change our behavior to become more healthy. For example, more often than not our good intentions to exercise more or to eat fewer unhealthy snacks fail miserably…

Effectiveness of an early intervention program for anxiety-prone toddlers in the Netherlands

The gas prices now exceed 300 euros per megawatt hour – a record. The transition from fossil (natural gas, coal, oil) to renewable energy is needed and soon. But how do you get a society (and its citizens) to switch to sustainable energy?

In this thesis, we have studied the potential of the zebrafish larval model in studying the ECS, as a complementary model to the existing rodent models.

This summer, political scientist Thijs Vos received the Kaare Strøm prize for his paper ‘Power or Ideology? What structures legislative voting behaviour in Dutch municipal councils, ideology or coalition-opposition dynamics?' He was awarded the prize during the ECPR summer school on parliaments in F…

Eveline Crone, professor of neurocognitive developmental psychology at Leiden University, has been awarded the Dr Hendrik Muller Prize for Behavioural and Social Sciences by KNAW.

Personality is genetic in zebrafish: risk-taking parents have risk-taking children. These are the findings of research by Christian Tudorache and his team published in BMC Neuroscience.

Exclusion elicits the same response in children as in adolescents and adults. That is what psychologist Mara van der Meulen found when she studied brain activity in primary schoolchildren. ‘What is new for us is that it is the same in childhood as later in life.’ Doctoral defence on 10 December.

Marie-Jeanne Holveck and Katharina Riebel from Behavioural Biology at the Institute of Biology at the Faculty of Science published their research in Proceedings B of The Royal Society.

Leiden psychologist Wilco van Dijk and communication scientist Jaap Ouwerkerk of VU University Amsterdam published a book about the emotion Schadenfreude. Van Dijk tells about Schadenfreude on BBC radio 4 All in the Mind.

George Floyd's death still leads to fierce protests against police violence and racism on a daily basis in the United States and abroad. We asked Paul Wouters how he experiences these developments and what this will mean for our faculty.

An international group of scientists has discovered that certain cells of our immune system – the so-called T cells – communicate with each other and work together as a team. To fight an infection they stimulate each other’s growth, but at the same time, they inhibit each other when there is a surplus…

We should assume that animals can have feelings too. From an ethical point of view this should inform our dealings with animals, researchers from Leiden University and Utrecht University argue in an opinion article that was published in the scientific journal Affective Science on Thursday 10 March.
