If a new method has been developed to recognize and treat a (neuro-)psychological disorder or related behavioral factors, it cannot yet be used directly in clinical practice. First, the method should be evaluated, preferably in randomized controlled trials.

A research into for whom, when and why the Cool Little Kids intervention works.

How can we implement the technique of pharmacological resting-state fMRI to improve the diagnosis of dementia?

The researchers examine the Council of the European Union's voting behaviour between 2010 and 2021 and the impact of different independent variables.

Due to the modern techniques of combinatorial chemistry and high-throughput screening, data on the biological activity of many millions of compounds is known. However, it is still very difficult to transfer this data into knowledge: if we know that compounds A and B bind to a certain protein with high…

How can zebrafish models be used to gain a better understanding of host-pathogen interaction mechanisms and to screen new drugs for infectious disease treatment?

Of the 109 Spinoza Prizes that have been awarded since 1995, 26 have gone to researchers from Leiden University. The NWO Spinoza Prize is the highest Dutch award in science. The younger NWO Stevin grant goes to researchers who have achieved great success in the field of knowledge utilisation for society.…

This subproject of 'From Homo Economicus to Political Animal' analyzes Greek economic thinking in late 5th- and 4th-century philosophical circles.

In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

Leiden chemists have proposed a new model for enzymatic reactions, in which the flexibility of the substrate is much more important than previously thought. Their results are paradigm-shifting and could have major implications for drug research and enzyme engineering. Publication in Angewandte Chemi…

Toward optimal measurement and greater understanding of youth cognition in school refusal and cognitive behavioural therapy outcome

This study interrogates contemporary and historical uses of barbarism, arguing that barbarism also has a disruptive, insurgent potential.

From Crisis to Critique

This anthology contributes to a historically grounded understanding of the complex relationship between Christian missions and the roots of humanitarianism and its contemporary uses in a Middle Eastern context.

This collection considers such issues as the cognitive, linguistic and emotional benefits of speaking two languages, the perceptions, attitudes and issues relating to identity in minority language areas, and the number of grammatical aspects amongst those who speak these minority languages.

Subjects Barbarian, Monstrous, and Wild responds to a contemporary political climate in which historically invested figures of otherness—barbarians, savages, monsters—have become common discursive currency.

On 25 Februarry 2021 Hart Bloomsbury brings out a monograph by Frans-Willem Korsten: Arts as an Interface of Law and Justice: Affirmation, Disturbance, Disruption. Its working title was 'Annoyance' but that did not sell. A sign in itself; most struggles for justice have been considered as annoying.

Pre-modern long-distance trade was fraught with risks which often created conflicts of interest. The ensuing disputes and the ways the actors involved dealt with them belong to the field of conflict management.

Over the last decades, the systematic investigation of urban settlements in Central-Tyrrhenian Italy led to the discovery of a growing number of contexts revealing both direct and indirect evidence of artisanal workshops. Such research commitment has yielded a vast amount of new data that greatly contribute…

Compact Cinematics challenges the dominant understanding of cinema to focus on the various compact, short, miniature, pocket-sized forms of cinematics that have existed from even before its standardization in theatrical form, and in recent years have multiplied and proliferated, taking up an increasingly…

The philosopher and psychologist G.F. Stout was the teacher of Moore and Russell around 1894. This book shows that Stout's ideas have played a role in Moore and Russell's development from their early idealism towards analytic realism, where Stout's ideas often find their origin in early phenomenolog…

In a new study, we found that when we are exposed to potential harm to the other person, it improves our automatic attentional processes to avoid harm to that person.

This book offers a detailed analysis of social policy in Ecuador, covering its evolution over the past four decades. It examines how social relations and institutional frameworks have influenced concepts of well-being, the implemented policies, and the outcomes achieved.

Un)timely Crises explores how ‘crisis’—as a narrative, concept, grammar, and experience—structures time and space. This collectively written volume extends Bakhtin’s ‘chronotope’ to challenge mobilizations of crisis within neoliberal governmentality. The book explores how contemporary crises can trigger…

The double issue of kritisk etnografi – Swedish Journal of Anthropology, has a question: Is Europe skilling for sustainable food? The two guest editors, Professor Maris Boyd Gillette from the University of Gothenburg and Professor Cristina Grasseni from Leiden University, have convened an esteemed…

Considering the ways in which the ‘global turn’ is changing the theory and practice of historical disciplines, Explorations in History and Globalization engages with the concept and methodology of globalization, challenging traditional divisions of space and time to offer a range of perspectives on…

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

How does contemporary art and culture represent nuclear contamination in post-nuclear landscapes?

This thesis analyses the existence and the functioning of the urban labour market in the early Roman empire by looking at the crucial influence of social structures, such as the family and non-familial labour collectives.

To be able to measure small forces or small deviations from Boltzmann, the external vibrations at the resonance frequency must be very low. To achieve this, we have developed a very soft vibration isolation system and combine it with several other measures to reduce vibrations in our dilution refrigerators.…

Positive expectations can influence sensations of itch and evoke placebo effects, whereas negative expectations can trigger nocebo effects in itch. There is evidence that placebo effects can occur even when people know that they are taking a placebo. Little is known about how these so-called open-label…

This study aims to answer two main research questions: (1) What are the main predictors of work ability in employees with migraine? (2) Can we optimise work ability in employees with migraine using a web-based intervention focused on these relevant predictors?
