This multidisciplinary minor provides students with knowledge on how and why humans became the way they are. The minor focuses on the evolution of the species Homo sapiens from other hominin lineages and animal ancestors, and on the various factors shaping this process. Not only is human evolution of…

This article, by Sara Perlstein, explores how perceived social acceptability shapes whether people talk about risks, showing that risk perceptions and conversations are socially negotiated rather than purely individual.

In this course, you will develop an understanding of evolutionary processes and their formative power. You will see how evolution has shaped biodiversity, and continuously influences our daily life.

Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

Het bestrijden van agressieve belastingplanning is een grote uitdaging voor overheden die een eerlijk belastingstelsel willen creëren. In deze minor onderzoek je hoe individuen en bedrijven gebruikmaken van juridische mazen in de wet om hun belastingen te minimaliseren, en wat overheden doen, zowel…

Bicarbonate buffer is largely found in nature due to its ability to regulate pH variations around neutral values. As the pH changes, so does the speciation of the buffer.

Veel van de grote uitdagingen van de 21ste eeuw (klimaatverandering, internationale migratie, financiële instabiliteit, sociaal-economische ongelijkheid) vinden hun oorsprong in de organisatie van de wereldeconomie. Elke oplossing voor de grote uitdagingen van de wereld vereist daarom krachtige beleidsinterventies…

In this top-rated course, you will learn how the European Union prepares and decides on policy, and how policy is transferred to member states and implemented by various authorities. It discusses the challenges of the European multi-level governance structure and the main causes of policy failure or…

One of the most important puzzles in modern astrophysics is the nature of dark matter.

The growing demand of energy indicates that global energy resources in the form of fossil fuels will not be sufficient in the future. In order to solve potential future energy problems development of a sustainable hydrogen economy is highly desirable.

The role of the interfacial environment during electrochemical reactions has been increasingly valued, especially for those reactions involving protons or hydroxyl ions.

Overheidsbeleid is vaak het onderwerp van alomtegenwoordige en diepe morele onenigheid. Morele onenigheid, gedefinieerd als het verschil tussen en verzet tegen principiële morele argumenten, kan voorkomen tussen beleidmakers, verschillende politieke partijen en individuen en het bredere publiek.

This thesis investigates the structural evolution and assembly of galaxies since the first few billions years after the big bang.

The goal of this thesis is to understand how interfacial parameters, such as the addition of organic additives, bulk pH or metal cations of the electrolyte, affect the relevant electrocatalytic reactions, i.e. electrochemical CO2 reduction reaction or hydrogen evolution reaction.

In de afgelopen drie decennia is er een sterke toename van het aantal denktanks in de meeste westerse democratieën, waarbij zij steeds meer gezien worden als belangrijke spelers in beleidsprocessen. Toch blijft hun precieze bijdrage aan beleidsvorming gecontesteerd.

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

Pulsars were first discovered in 1967 and since then the population has grown and expanded over several wavelengths.

Plants produce an astonishing variety of secondary metabolites (SMs) which are thought to play vital roles in the fitness of plants through ecological interactions.

Whilst government’s ability to design ‘context-specific’ regional innovation policy is generally assumed to depend on the region’s decision-making power, the aim of this study is to investigate how regional government matters. In order to open up the black box of policy design, the study develops a…
