Madeleine O. Hosli & Jaroslaw Kantorowicz analyze EU states' foreign policy divergence at the UN General Debate, assessing if Lisbon Treaty reforms increased EU cohesion or if states maintain distinct positions.

Although exposure therapy is the gold-standard treatment of posttraumatic stress-disorder (PTSD), only half of the patients adequately benefit from it. Based on recent insights into the mechanisms of extinction, this project examines strategies and techniques to improve exposure treatment outcome in…

This article discusses the degree of independence that is required for national human rights institutions to function successfully.

What is the relation between brain development and social and cognitive development across childhood, adolescence and adulthood?

Why do some children confront social challenges with confidence, whereas others experience difficulties? What is the role of child temperament and child emotional dispositions? What is the role of parenting? This project aims to shed light on the mechanisms explaining shyness and confidence in response…

This article studies the influence of framing on preferences for cooperation with the EU.

A defining fixture of our contemporary world, video games offer a rich spectrum of engagements with the past.

The International Labour Organisation (ILO) was established in 1919 based on the premise that social justice is a condition for lasting peace. On February 2019 the ILO celebrated its 100th anniversary with an international symposium to consider the future of the ILO.

How do individuals make decisions? What determines the quality of group decisions? When and why do people cooperate with others? How does intergroup competition evolve?

The master's specialisation Molecular, Cellular and Organismal Biology at Leiden University examines the molecular mechanisms underlying health and disease and how cells and organisms adapt to environmental factors.

It has now been well established that shocks and turbulent motions in the intra-cluster medium (ICM) generated through cluster mergers can produce large-scale synchrotron emission.

On 19 May 2020, Xuechan Ma defended her thesis 'Moving towards Coexistence and Cooperation: The Spratly Islands and International Law'. The doctoral research was supervised by Prof. N.J. Schrijver.

Inflammatory skin diseases such as psoriasis and atopic dermatitis can severely impact both the physical and social aspect of a patient’s life. Aberrant inflammatory responses are thought to be a major causative factor in these disorders, but an abundance of different factors contribute to the development…

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

Synthetic microswimmers take an important place within the interdisciplinary field of active soft matter.

Robotics, using social mechanisms like hormonal modulation, may accelerate our understanding of core sociality principles. By looking at social robotics through an evolutionary lens, we propose this field as a promising framework to investigate the fundamental bricks of sociality from an evolutionary…

Phosphorylation affects all four major biomolecules – proteins, lipids, carbohydrates and nucleic acids – and plays a pivotal role in the most fundamental cellular functions.

This book contextualizes the use of terror as part of wider movements of political contention, demonstrating that terroristic innovation occurs as part of wider historical processes rather than in a vacuum.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

This project aims to explore, in general, what explains civil servants’ attitudes and behavior, and, in particular, why some civil servants are more committed to professional norms and public service values – such as impartiality, equity, efficiency, and innovation – than others.

The overarching goal of this thesis is to set the foundations, but also make the first essential steps towards establishing a comprehensive, mesoscopic, hydrodynamic theory of epithelial tissues. The stage is set by an exhaustive study of topological defects in passive p-atic liquid crystals, singularities…

The recent terrorist attacks in Europe are presumably not just acts committed by individuals, but acts facilitated by larger jihadist networks. But how do such networks operate? Understanding their modus operandi can be useful knowledge to counter terrorist threats.

The aim of this project is to explore the use of statistical interaction models to quantify cross-omics and omics-drug interactions in large-scale clinical and experimental datasets

In recent years, the question why citizens (do not) support democratic innovations has attracted increasing academic attention. In this research note, Van Der Does & Kantorowicz for the first time empirically verify what drives citizens’ instrumental considerations in their evaluation of a DI.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.
