Playing a role – but which one?
How public service motivation and professionalism affect decision-making in dilemma situations. Individuals who work in the public sector see themselves confronted with conflicting values, contradictory demands, and the need to serve an at times difficult to define ‘public interest’.

Sweeping vacuum gravitational waves under the rug
One of the most important correlation functions in physics, especially in cosmology, is the energy density, which describes how much energy is present at each point in spacetime due to matter fields. A key contribution to the energy density of the primordial universe comes from gravitational waves (GWs),…

Density functional theory is an accurate predictor for variation with geometry of barriers for reactions on metals
A semi-empirical version of the specific reaction parameter approach to density functional theory (SRP-DFT) has been remarkably successful at predicting dissociative chemisorption probability vs. incidence energy curves for reactions on metal surfaces. New quantum Monte Carlo (QMC) calculations on the…

Highly Accurate Simulations and Benchmarking of Molecule-Surface Reactions
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.

Mathematical models for mechanically induced morphogenetic pattern formation
During the development of the (human) body from a single fertilized egg, organs and structures must form. The development and growth of biological forms is called morphogenesis.

Geometry of Vegetation Pattern
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.

Re-envisioning nature: the representation of post-nuclear landscapes in contemporary art and culture
How does contemporary art and culture represent nuclear contamination in post-nuclear landscapes?

The urban labour market of Roman Italy
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.

Observing what cannot be observed: computational electrochemistry from carbon to hydrogen
In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

Logarithmic Hochschild homology and cohomology
In this thesis, we explore a Hochschild homology and cohomology-like notion for logarithmic schemes.

Development of highly accurate density functionals for H2 dissociation on transition metals
Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

From Homo Economicus to Political Animal
Who is Economic Man? Every economic paradigm presupposes an anthropology, a theory of human nature. This project explores the anthropologies presupposed and produced by ancient Greek economic texts, and the specific knowledge forms that shape these anthropologies.

The unit residue group
The unit residue group, to which the present thesis is devoted, is defined using the norm-residue symbol, which Hilbert introduced into algebraic number theory in 1897.

Meet this year's Lorentz Professor Renata Kallosh: 'Lorentz is my hero in physics'
Professor Renata Kallosh (Stanford University), one of the world’s leading theoretical physicists, will be this summer’s Lorentz Professor at the Leiden institute for theoretical physics. Her main areas of interest are cosmology and string theory. She studied physics in Moscow, where she also obtained…
