This project proposes an integrated and comparative study on the syntactic, semantic, prosodic and processing aspects of in-situ wh-questions, taking the Grammar-parser correspondence hypothesis (Phillips 1996, 2003) as a guiding principle.

To ensure that the growing global flows of labour migrants are guided correctly, we need knowledge. Why do people leave home, why do they go to specific countries, and how can that choice be influenced? And what are the consequences of their leaving for the people who stay?

Inequality and violence are the two biggest issues in South Africa. What is the underlying cause? Could they be linked to rivalling groups, economic factors, government policy or all of the above? To understand social issues, it is important to study them within their context. The extended case study…

The Horizon 2020 project CoSTREAM aims to improve our understanding of the co-occurrence of stroke and Alzheimer’s disease. It has long been known that both diseases share underlying causes, but their exact interaction or link is not fully understood. CoSTREAM combines multiple factors to identify and…

How do the pathways of Dutch converts to Islam involved in jihadist movements differ from those of Dutch converts who are not, in terms of their life prior to Islam, their conversion experience and the form of involvement with the Islamic community after conversion?

This PhD project analyses the politics and aesthetics of depictions of torture in American and European ‘war on terror’ films.

We are a dynamic research group at the Leiden Institute of Physics. Our aim is to explore and understand quantum materials, including strange metals, high-temperature superconductors, and quantum critical electron matter.

The complexity of an intelligence problem determines to a great extent the certainty that can be provided by intelligence and security services.

In today's volatile market environments, companies must be able to continuously innovate. In this context, innovation does not only refer to the development of new products or business models but often also affects the entire organization, which has to transform its structures, processes, and ways of…

Pathways of toxicity

The work described in this dissertation contributes to a better mechanistic understanding of nanoparticles in vivo. To achieve that goal, we used the zebrafish as a highly predictive pre-screening model of nanoparticles.

The objective of this project is to fundamentally improve our understanding of the ways in which science progresses. Empirical studies have used bibliographic metadata to provide relevant insights, but these studies have failed to tell us how science progresses. Supported by computational advances and…

An interdisciplinary collection of the best international scholarship on Muslim youth.

Leiden psychologist Wilco van Dijk and communication scientist Jaap Ouwerkerk of VU University Amsterdam published a book about the emotion Schadenfreude. The authors describe what the emotion Schadenfreude really is, when people experience the emotion, and what role it plays in social relations.

This study delivers a comprehensive picture of the causes of radicalization in the Eastern and Southeastern regions of Turkey. It demonstrates how regionally specific factors enable ideologically disparate terrorist groups to recruit and radicalize from the same population.

This book provides a comparative analysis of the process of breach across ten different European jurisdictions by identifying and elaborating a number of key analytical themes through which the different systems can be compared and evaluated.

Due to their central physiological roles in living organisms, retaining beta-glycosidases have been the subject of tremendous research efforts to examine their structure/function relation using numerous biophysical and biochemical approaches.

There is considerable need for improved skin models to develop safe and efficient drugs for skin delivery as well as for cosmetic and chemical product testing on the skin.

How the global distribution of vegetation stands dominated by arbuscular and ectomycorrhizal plants relate to principle aspects of belowground carbon accumulation processes?

When does teacher agency occur in the university context, and how is this related to teaching?

What are ‘missing links’ in research on teacher professional development trajectories? We focus on the role and development of teacher facilitators in designing and implementing (collaborative) professional development trajectories.

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?

It is the aim of this project to better understand how the physical properties of lipids influences the structure and overall barrier function of the skin.

You can ask virtual assistant Siri about the weather, but you can’t have a real conversation with it yet. You can’t refer to anything that’s been said before, or ask the system why it says what it says. Stephan Raaijmakers, Professor by Special Appointment from TNO, hopes to change this.

Understanding others’ emotional behavior is essential for navigating daily social life. But how is such an understanding achieved? The eye-tracking study by Yung-Ting Tsou and colleagues shows that children with hearing loss adopt a unique visual strategy that makes uses of explicit visual information…

This research programme seeks to understand the dynamics in the relationship between social media, mobile telephony and the social fabric under duress in Africa's mobile margins. It combines studies on mobility/migration, conflict and communication in an attempt to uncover these new dynamics, which…

Neurodegenerative diseases, including Parkinson’s disease (PD), are increasing in prevalence due to the aging population. Despite extensive study, these diseases are still not fully understood and the lack of personalised treatment options that can target the cause of the diseases, rather than the symptoms,…

How presence, abundance and enzymatic activities of AM and EM fungi differently affect soil carbon sequestration processes?

This study focuses on increasing our understanding of the different pathways converts take during conversion to Islam.

How can the transport of molecules in living cells help to target medicines at exactly the right place?

Cellular stress response pathways are activated upon exposure to chemicals and help organisms deal with various molecular dangers (e.g. oxidative stress). When these pathways become hyper-activated an adverse response takes place and cells die, which may lead to organism-level toxicity such as drug-induced…

The aim is to discover where differently shaped metal nanoparticles distributes in Danio rerio, linking the distribution with genomic responses and so come up with a Mode of Action.

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

Dit proefschrift beschrijft een collectie aan alternatieve strategieën voor het begrijpen, ontwerpen en toepassen van lipide nanosystemen, waarin de rol van de bio-nano interacties centraal staan. In het bijzonder wordt gekeken naar de interactie van RNA-lipide nanosystemen, bekend van de toepassing…

The Persian Empire (539-330 BCE) was the first world empire in history. At its height, it united a territory stretching from present-day India to Libya - and it would take 2,000 years before significantly larger empires emerged in early modern Eurasia. This territorial sweep is both a source of fascination…
