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.

This thesis addresses the chemical processes that determine the compositions of giant planet atmospheres.

This book is the first comprehensive presentation of the archaeology of Syria from the end of the Paleolithic period to 300 BC.

The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.

While Nietzsche's works and ideas are relevant across the many branches of philosophy, the themes of contest and conflict have been mostly overlooked. Conflict and Contest in Nietzsche's Philosophy redresses this situation, arguing for the importance of these issues throughout Nietzsche's work.

This thesis investigated the extent to which participation of school students in decision-making processes can be achieved, including through participatory action research (PAR) in teacher education.

Childhood sexual abuse is a common problem, with approximately one in five girls and one in 13 boys worldwide experiencing some form of sexual abuse before the age of 18. Despite its high prevalence, many individuals remain silent about these experiences, often delaying disclosure for years, with one…

This book is about the archaeology of indigenous peoples who thrived across the Caribbean, the Guianas, and the Lower Amazon basin just before the European invasion, and who also remained central to the early history of conquest and colonization.

For the first time, a group of international and interdisciplinary researchers led by Karline Janmaat and her former MSc Student Chirag Chittar, have tested the several hypotheses on music simultaneously in a modern foraging society during their daily search for tubers – their staple food. They found…

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).

On 14 January 2021, Joost Westerweel defended his thesis 'Lokale democratische innovatie'. The doctoral research was supervised by Prof. G. Boogaard and Prof. M.J. Cohen.

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

The Brazilian economy has long been defined by its enormous potential. Over the past 30 years, some of this has at last been realised. Latin America’s largest economy has rapidly risen in global importance while poverty at home has declined. Yet, despite periods of progress, Brazil remains prone to…

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.
