Democratic citizenship refers to the capacity and willingness of citizens to actively influence the functioning of state institutions. While considered a vital correlate of democratization and the rule of law, its largely western-oriented literature rarely studies the forms of democratic citizenship…

The group of Dr. Roxanne Kieltyka designs and synthesizes molecules that self-assemble into polymeric materials using specific non-covalent interactions. These substrates can be used for numerous applications in medicine ranging from disease detection to cell delivery depending on the (bio)molecular…

For optimization problems, it is often unclear how to choose the most appropriate optimization algorithm. As such, rigorous benchmarking practices are critical to ensure we can gain as much insight into the strengths and weaknesses of these types of algorithms.

Marieke Liem, Professor Social Resilience and Security at Leiden University, and Katharina Krüsselmann, PhD candidate at Leiden University and Manuel Eisner mapped the flow of homicide cases with the help of a systematic review.

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.

Biodiversity in the Netherlands is having a tough time. Professor of Natural Capital Koos Biesmeijer combines research with practical advice: from the greening of industrial parks to solutions inspired by hi-tech nature. Inaugural lecture 9 March.

As museums face more scrutiny and are being demanded to decolonize, there are opportunities for Dominican museums to adopt a critical perspective and turn their collections and exhibitions into connections to our cultural past, present, and future.

This project looks at the Ancient Greek language from the perspective of the ordinary writer. A large corpus of more than 60.000 Greek texts on papyrus, from private letters to petitions and contracts, offers an excellent opportunity to study the Greek language as written by non-literary writers in…

Why do historians so often talk about objectivity, empathy, and fair-mindedness? What roles do such personal qualities play in historical studies? And why does it make sense to call them virtues rather than skills or habits?

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…

Edward Elgar has recently published an edited volume entitled “Realising Protection from Age Discrimination: International, Regional, and National Perspectives”. The book has been edited by Helen Meenan (visiting professor at Kingston University, UK) and Christa Tobler (Europa Institutes of the Universities…

This project develops a scientific method to extract clinically relevant new information from patient forum websites that discuss patient experiences concerning e.g. medication, nutrition, co-morbidities, genetic factors etc.

In this article, Thijs van Dooremalen and Philip Smith investigate how public discourse of heatwaves have shifted in British newspaper discourse, drawing on Raymond Williams’s theory of dominant, emergent, and residual cultural patterns to analyse changes in language and interpretation over recent d…

This historical study argues that the Mandaean religion originated under Sasanid rule in the fifth century, not earlier as has been widely accepted. It analyzes primary sources in Syriac, Mandaic, and Arabic to clarify the early history of Mandaeism.

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.

The central aims of MicroClock project are to describe the B. subtilis circadian clock at molecular and functional levels, and discover the mechanisms of clock-regulated bidirectional signaling between B. subtilis and the model plant Arabidopsis

What is the impact of Indonesia’s democratization process on everyday state-citizen relations?

Serge Rombouts is a physicist whose PhD thesis was about functional MRI (fMRI). This visualises activity in regions of the brain. The appealing images of glowing brain regions that emerge from the computer are the result of calculations. According to Rombouts, this isn’t proper artificial intelligence.…

How are contemporary art practices from Southeast Asia negotiating notions of art and tradition?

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

Hydrocarbonylation of alkenes with carboxylic acids in synthesis of carboxylic acid anhydrides is relatively less explored. We herein present a study and optimization of a palladium-catalyzed hydrocarbonylation reaction of alkenes using carboxylic acids as the nucleophile, by which acid anhydrides can…

The marine shipping industry is one of the strongest emitters of nitrogen oxides (NOx), a pollutant detrimental to ecology and human health. Over the last 20 years, the pollution produced by power plants, the industry sector, and cars has been decreasing.
