Individuen die werken in de publieke sector zien zichzelf geconfronteerd worden met tegenstrijdige waarden, tegenstrijdige eisen en de noodzaak van het dienen van het soms moeilijk definieerbare publieke belang.

Leidse wetenschappers onderzoeken groepsgedrag. Ze ontdekten onder meer dat mensen zich waarschijnlijk instinctmatig opofferen voor een mede-groepslid. Met dit soort inzichten kunnen we sociale processen in een wijk of binnen een bedrijf beter begrijpen en beïnvloeden.

Quantum computing is an emerging technology, which holds the potential to simulate complex quantum systems beyond the reach of classical numerical methods.Despite recent formidable advancements in quantum hardware, constructing a quantum computer capable of performing useful calculations remains challenging.In…

This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…

Het Netherlands Centre for One Health (NCOH) is uitgebreid met de Universiteit Leiden en het LUMC. De komst van de Leidse instellingen versterkt het academische netwerk waarin onder andere het probleem van antimicrobiële resistentie wordt onderzocht.

What determines civic engagement in transboundary hydropolitics and why has it been muted in the Eastern Nile Basin?

Researchers from the Department of Economics - Kees Goudswaard, Koen Caminada, Marike Knoef, Pierre Koning and Olaf van Vliet - have been awarded a grant of one million euros by Instituut Gak to investigate self-sufficiency and social protection.

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.

Onze decaan Rick Lawson en Anette van Sandwijk, Hoofd Bureau Internationaal Onderwijs, reisden van 5 tot en met 16 april langs een aantal partners in de Verenigde Staten. Leiden Law School heeft al lange tijd samenwerkingsverbanden met een aantal vooraanstaande Amerikaanse Law Schools. Doel van de reis…

Anthropogenic change is reshaping ecological systems, raising concerns about increasing transmission of infectious diseases. Among these, mosquito-borne diseases may be particularly sensitive to environmental change, as their transmission depends on vector populations.

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.

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Humans can see the world through the eyes of other humans and imagine what they know, want, and intend. This competence is known as Theory of Mind.

To an algebraic curve C over the complex numbers one can associate a non-negative integer g, the genus, as a measure of its complexity.

Prostate cancer (PCa) is one of the most prevalent cancer in males.

In my thesis I study Majorana fermions from three different perspectives. The first one corresponds to non-interacting Majorana fermions that, however, pose non-trivial topological properties. The second one corresponds to strongly interacting Majoranas and the third to relic neutrinos. No one knows…

Our recent excavations have focused on the more recent New Kingdom/Late Period (ca. 1500-332 BCE) material.

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

In this book liposomes are explored as delivery system for allergen-specific immunotherapy. Both cationic and anionic formulations are prepared with Bet v 1, one of the allergens in birch pollen.

The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.

In this thesis, I targeted the orchid genus Lepanthes, one of the six genera of angiosperms that surpasses 1,000 species in the Neotropics, as a study model to investigate the evolutionary processes that promoted species diversifications.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

Thermodynamics is one of the founding scientific pillars that has helped us better understand heat engines, biology, ecosystems, and even black holes. While it fundamentally describes large systems by examining the bulk behavior of their constituents, it is anchored in the statistical equivalence of…

Cardiovascular disease is the number one cause of death worldwide. The most important risk factor for developing this disease is high cholesterol levels in the blood.

Agrobacterium tumefaciens, a gram-negative plant pathogen belonging to the family Rhizobiaceae, is the causative agent of crown gall disease, which can affect many plant species including agronomically important ones.

The origin and evolution of galaxies are closely linked to many different physical phenomena.

Every organisms in the tree of life faces the same challenge: the length of its DNA exceeds the volume of the cell it needs to fit in. Several strategies have evolved to solve this problem, one of them being the expression of proteins that bind and organize the DNA.
