Our library contains around 23,000 books, journals and historical documents under the care of a specialized librarian.

This project tries to explain the persistence of this cultural repertoire by zooming in on (1) interaction between idioms (cultural repertoires) available to scholars at certain points in time, (2) mechanisms that help transmit repertoires across time and place, and (3) rhetorical purposes for which…

As a student residence permit holder you must meet a number of obligations during your stay. Make sure to familiarise yourself with these obligations before submitting your visa/residence permit request.

Painstaking research in Dutch and Portuguese archive materials, so far poorly assessed on the topic of social relations, reveals intense and intricate associations between different European individuals both in terms of ethnicity and social strata.

On the 26th of September, Cosmas Rai Amenorvi successfully defended a doctoral thesis. Leiden University Centre for Linguistics congratulates Cosmas on this achievement!

With the advent of multicore processors and data centers, computer hardware has become increasingly parallel, allowing one to run multiple pieces of software at the same time on different machines. Coordination of these pieces is best expressed in a coordination language as an explicit interaction protocol…

In a typical glycosylation reaction, a donor is activated to form a (variety of) electrophilic species which can react with a nucleophilic acceptor, following a reaction mechanism having both SN1 and SN2 character.

Scientific integrity is an essential element in the PhD trajectory and is addressed in several different settings.

From Los Angeles to Tokyo, Urban Sociolinguistics is a sociolinguistic study of twelve urban settings around the world.

Psychoeducational Assessment, Intervention and Rehabilitation (PAIR) publishes high quality articles on theoretical and empirical research regarding psychological and psychoeducational assessment, intervention, and rehabilitation in all areas related to cognitive and socio-emotional development.

The goal of this study is to systematically investigate how intonation (speech melody) is conveyed in whispered speech.

How were (post) colonial migrants included in post-war welfare systems?

On 18 May 2022, Annelien Bouland defended her thesis 'Please give me my divorce: an ethnography of Muslim women and the law in Senegal'. The doctoral research was supervised by Prof.dr. J.M. Otto, Prof.dr. M.M.A. Kaag and Dr.ir. C.I.M. Jacobs.

What are the foundations of the regulation of blasphemy, and in which manner, in legal as well as in extra-legal terms, has blasphemy developed over the last decades?

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

This thesis describes the design and synthesis of fragments of various cell wall carbohydrates of the Streptococcus species, including the branched Group B-specific antigen (GBC) of Group B Streptococcus, glycerol phosphate (GroP) modified group A carbohydrate (GAC), and the O-acetylated type 1 capsular…

The transition period in which men become fathers might provide an important window of opportunity for parenting interventions that may produce long-term positive effects on paternal care and, consequently, child development. Existing prenatal programs traditionally focus on maternal and infant health…

This work has described synthetic strategies towards well-defined structures resembling capsular polysaccharide (CPS) fragments, CPS mimics, teichoic acid (TA) fragments as well as a third-generation ring-closing tandem metathesis (RCM) linker to better exploit the potential of automated synthesis.

HomininSpace is an agent based modelling and simulation system in which fluctuating carrying capacity is the key attractor for hominin dispersal. A parameterized and spatially explicit reconstructed palaeo-environment models available energy in the form of secondary biomass using reconstructed climate…

One of the main challenges in the development of an effective anti-cancer vaccine is the generation of an adequate and directed cellular immune response.

This thesis describes the use of a combined approach of computational and experimental techniques to gain novel insights to understand the glycosylation reaction and its reactive intermediates.

Carbohydrates, or sugars, are the most diverse and most abundant biomolecules known. However, the isolation of carbohydrate samples in sufficient amounts and purity is often impractical or even impossible, so the chemical synthesis of glycosides becomes relevant. The glycosylation reaction, in which…

The project investigates how bilingual speakers navigate lexico-syntactic features, including grammatical gender, classifier systems, and the linear order of adjectives and nouns, across Spanish and Chinese in both unilingual and bilingual contexts.

On the basis of the characteristic aspects of a picture, certain computers can tell us what the picture is showing. They can learn this in the same way that young children are able to learn to recognize images. Further improving these techniques opens the way to a whole range of new applications. Biology…

Schistosomiasis is an acute and chronic disease caused by blood dwelling parasitic trematodes of the genus Schistosoma, and it is classified as the second most socioeconomically devastating parasitic disease, second only to malaria.

Pseudomonas Aeruginosa is a Gram-negative bacterium which can form biofilms, increasing its resistance against antibiotics and the host immune system. Polysaccharides are an integral part of this biofilm, one of these polysaccharides is called Psl. PslG is a glycosidase, able to cleave this polysaccharide,…

This Thesis describes a strategy to synthesize 1,2-cis-oligosaccharides modulated by additives, such as dimethylformamide (DMF), triphenylphosphine oxide (Ph3P=O) and N-methyl(phenyl)formamide (MPF), using building blocks that carry solely benzyl type protecting groups and are therefore of uniform r…
