How does the criminal justice system in Indonesia safeguard the rights of and access to justice for witnesses and victims?

This special issue focuses on emerging trends in the implementation of the WPS agenda. In reviewing the resolution 20 years since the passing of Resolution 1325, Newby and O'Malley have highlighted the gaps in implementation.

This perspective addresses four challenges facing theorists whose aim is to make quantitatively accurate predictions for reactions of molecules on metal surfaces, and suggests ways of meeting these challenges, focusing on dissociative chemisorption reactions of H2, N2, and CH4.

Implementing all kinds of change and introducing new structures, far-reaching rules and administrative systems may sometimes seem to distract an organisation from its purpose. Furthermore, there is growing recognition of the need of staff of public organisations to find more meaning in their work: the…

Leiden University College The Hague (LUC) offers a 3-year Bachelor's programme with a focus on Global Challenges: Peace & Justice, Sustainability, Diversity and Prosperity. The programme offers room for flexibility; you get to specialize in a major of your choice and combine this with a minor or electives.…

The intradermal administration route is attractive for vaccine delivery, because of the highly populated antigen-presenting cells in the skin. However, the skin’s main physical barrier, the stratum corneum, prevents vaccines from entering the skin.

Opportunities, challenges, and future perspectives of people-centered approaches in dynamic historic urban landscapes

Archaeological and related essays on the Jordan Valley in honour of Gerrit van der Kooij on the occasion of his sixty-fifth birthday

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.

The field and the classroom invites ethnographers to engage with critical and engaged pedagogies. Breaking down the barriers between fieldsite and lecture hall, this research cluster aims to interrogate the structures and values that shape anthropological and sociological education today.

Leiden archaeologists investigate how people in the past impacted their environment. Together with scientists, environmental scientists, and humanities experts, they use this information to draw conclusions about the present – and show what we can learn from it for the future.

In ancient times, the steppe in the hinterland of Petra (Jordan) was transformed into a green oasis. This project tries to shed insights in the agricultural, water management and societal processes resulting in this transformation. This will be accomplished by practicing an interdisciplinary research…

Evolutionary and ecological interactions affect species on genetic and phenotypic levels. This theme aims to understand these processes at multiple levels: from molecules to genomes to populations and to communities. Our research focuses on evolutionary responses to anthropogenic change, the role of…

Combining results from bibliometric analyses, a global sample of researcher opinions and case-study interviews, a new report reveals that although the benefits of open research data are well known, in practice, confusion remains within the researcher community around when and how to share research…

Identifying natural plant-associated bacteria that provide targeted inhibition of pathogens through the production of antimicrobial peptides.

In this publication, May Tamimova and Tahir Abbas researched the existing literature about violence and hatred against places of worship.

It is estimated that approximately 30% of all proteins require a metal to function. Investigating the relationship between metal-binding and peptide/protein folding allows us to uncover fundamental rules for creating metallo-peptides and proteins, which in turn leads to the creation of new structures,…

Today’s socio-economic challenges aren’t new. In the centuries after the retreat of the Roman state people with different backgrounds and with different ways of life somehow managed to build and maintain a complex economic system in northern Gaul that would produce the ruling dynasties of Europe.
