Legitimacy is generally a term that is associated with the state. The term surfaces when there are problems with state legitimacy—when it is lacking or absent. This present volume attempts to think through the relevance of the concept of legitimacy for other political actors than the state.

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

Does student and teacher gender affect students’ performance and what is the role of gender stereotypes in this relation?

How does the cluster bootstrap procedure in combination with various types of linear models perform in the analysis of longitudinal data, compared to other methods.

Het is een wijdverbreid idee dat (post-)middeleeuwse steden een sterfteoverschot hadden en zij slechts in leven konden blijven door de toestroom van migranten; een fenomeen dat bekend staat als het ‘urban graveyard’-effect. Over details valt te twisten, maar duidelijk is dat de stad en de dood dichter…

Scientists, including our faculty colleague Dr. Mike Field, studying an exceptionally well-preserved woolly rhinoceros have revealed details of what Britain's environment was like 42,000 years ago. The beast's remains were discovered in Staffordshire in 2002, buried alongside other preserved organisms…

In this thesis I highlight the applications of Oxford Nanopore Technologies (ONT) sequencing. This technique is a relatively new approach in the sequencing field, where nanopores are embedded in a membrane, DNA molecules are pulled through nanopores and an electrical current serving as the sequencing…

In this thesis, the role of plant-mediated soil legacy effects in shaping aboveground plant-insect interactions was investigated.

Marc Koper’s research focuses on electrocatalysis and electrochemical surface science for sustainable energy and chemistry. Reactions of interest are the redox reactions of the oxygen/hydrogen cycle (water oxidation, hydrogen evolution), the carbon cycle (reduction of carbon dioxide, oxidation of small…

On the 11th of January, Rasmus Puggaard-Rode successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Rasmus on this achievement!

The project seeks to explore the interplay of valuation and inequalities in science, using the interdisciplinary and planet-critical field of forest research as empirical case. It examines which/whose knowledge is recognised on what grounds, and how social dimensions like gender and geographical location…

Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

The first of the two volumes of this co-authored study has just been published by Metzler. The study explores the history of the concept ‘barbarism’ from the 18th century to the present and illuminates its foundational role in modern European and Western identity.

Continuous optimization is never easy: the exact solution is always a luxury demand and the theory of it is not always analytical and elegant.

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.

Constraint multi-objective optimization with a limited budget for function evaluations is challenging. This thesis tackles this problem by proposing new optimization algorithms. These algorithms are applied on holistic ship design problems. This helps naval architects balance objectives like cost, efficiency,…

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

Tomography is a powerful technique to non-destructively determine the interior structure of an object.Usually, a series of projection images (e.g.\ X-ray images) is acquired from a range of different positions.
