De wereldwijde ongelijkheid neemt steeds meer toe. Het is belangrijk om de oorzaken te weten zodat de toenemende ongelijkheid bestreden kan worden.

Op woensdag 15 september promoveert Jinxian Wang op haar proefschrift: Trends in social assistance, minimum income benefits and income polarization in an international perspective.

Statistical distributions in LCA and converting between different representations of these distributions.

The objective of this study is to better understand the distribution of microplastics in the environment. More specifically, we will quantify the abundance and distribution of microplastics on beaches.

What are the global relationships between environmental conditions and abundance of distinct types of mycorrhizal fungi in soil and plant roots?

Mycorrhizas are symbiotic associations between soil fungi and most plant species.

A novel mathematical model describes spatial-temporal drug distribution within one or more brain units, which are cubic representations of a piece of brain tissue with brain capillaries at the edges.

This research focuses on the distribution of chemical elements in protoplanetary disks, the birthplaces of planets. These disks form around young stars and contain gas and dust, from which planets grow. Ice plays a crucial role in planet formation, aiding the clumping of dust particles and influencing…

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.

Tom Buitelaar dat de micro-niveau discours van internationale organisaties zich imperfect aanpast aan macro-niveau veranderingen, waarbij aanpassing aan macrodruk wordt afgewogen tegen de toewijding aan persistente organisatorische waarden.

The Economics and Governance specialisation of the Master in Public Administration teaches you to formulate problem-solving approaches to concrete policy issues found at the intersection between economics and public administration. This specialisation is a unique joint offering of the Department of…

Het gebruik van ‘Big data’ is niet meer weg te denken binnen het wetenschappelijk onderzoek. Voor dit onderzoek maken we gebruiken van diverse grote databestanden.

This PhD-thesis analyses the relationship between the parties’ choices in the CPB Netherlands Bureau for Economic Policy Analysis’ assessments of the election manifestos and coalition agreements over the period 1986-2017, and tries to explain this relationship.

Galaxies form and live inside dark matter haloes. As a consequence, they are exposed to the tidal fields generated by the surrounding matter distribution: this imprints a preferential direction to the galaxy shapes, which leads to a coherent alignment on physically close galaxies, called intrinsic a…

We present an extensive study of methods for exactly solving stochastic constraint (optimisation) problems (SCPs) in network analysis. These problems are prevalent in science, governance and industry.

Natural history collections provide invaluable sources for researchers with different disciplinary backgrounds, aspiring to study the geographical distribution of flora and fauna across the globe as well as other evolutionary processes.

This thesis examines the link between simple molecules and the underlying structure and chemistry within protoplanetary disks - the birthplaces of planets.

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

This research project studies the distribution and impact of medieval malaria in the Netherlands.

In this dissertation non-parametric Bayesian methods are used in the application of robotic vision.

International trade has played a major role in defining the modern global economy. Trade, however, entangles the environmental pressures of economic sectors, giving the illusion of environmental improvements, while the opposite may be occurring.

Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

At the largest scales, two ingredients dictate the distribution of matter in the Universe. The first is dark matter, acting as an invisible scaffolding held together by gravitational forces.

Carbonaceous asteroids preserve a record of early solar system processes, where minerals and organic molecules, like polycyclic aromatic hydrocarbons (PAHs), offer clues to planetary evolution and prebiotic chemistry.

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

This thesis consists of two main parts. The first part (Chapters 2 and 3) deals with a class of Markov process called Quasi-Skipfree (QSF) processes.

This thesis discusses the physical and chemical processes than influence the composition of forming planets.

Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.
