Much attention has been paid to the exchange of objects, ideas, and people in the Caribbean. Networks of interaction connected local communities across pan-regional scales, shaping indigenous socio-political integrations and their responses in colonial situations. This work examines the poorly understood…

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

We examine how soil-derived legacy effects of plants structure natural ecosystems, determine aboveground plant insect interactions, and how we can use soil legacy effects to restore degraded ecosystems.

An archaeological/ethnohistorical study.

Dlshad Marf defended his thesis on 4 July 2016

This thesis is devoted to an in-depth examination of the various effects of disorder in the cuprate high-temperature superconductors.

Majorana fermions in superconductors are the subgap quasiparticle excitations that are their own antiparticles.

This thesis focus on the interaction between M dwarf stellar winds and Galactic cosmic rays and the possible effects on the habitability of exoplanets.

Galikyan’s dissertation examines how the multidimensionality of learner­learner interaction data and the multifacetedness of learner-learner interaction itself impact the measurement of learner-learner interaction in digital learning environments.

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

The aim of this research is to gain insight into the approaches of learning to teach. Teacher learning processes, feedback in novice-expert interaction and the impact of the interaction are explored.

The aim of this project is to explore the use of statistical interaction models to quantify cross-omics and omics-drug interactions in large-scale clinical and experimental datasets

In tracing intra-site, local and regional craft networks in Late Bronze Age Tiryns (Greece) the project aimed to understand technological changes, (dis)continuities and social practices from the Late Palatial until the Post Palatial periods in Mycenaean Greece.

There are about 35,000 students with chronic illnesses in the Netherlands. If they cannot receive education in the classroom, they may be able to do so from home or a hospital with hybrid education. The question in this study is: how can interaction with the teacher and fellow students be promoted?

In this thesis, classes of strongly interacting quantum field theories, have been studied.

A defining fixture of our contemporary world, video games offer a rich spectrum of engagements with the past.

If an algorithm has to learn to understand language, simply having a lot of data doesn’t help much. Like us, a computer has to learn the language in interaction with others. Tessa Verhoef is fascinated by how this interaction works.

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

Can we distinguish the effects of pesticides from other abiotic and biotic factors that occur in the field? And how do these factors interact with pesticides?

Research in the van Exter lab focuses on quantum aspects of light and light-matter interaction. One of our long-term goals is to develop a reliable quantum memory, based on a single emitter in an open micro cavity.

Are there general principles or values that should govern our actions as moral agents and/or as political subjects?

To what extent can contingent, formative feedback in lectures, facilitated by web-based ICT, increase students’ self-efficacy and (academic, behavioral, and cognitive) engagement? And how are self-efficacy and engagement influencing students’ performance and course evaluations?

This is a joint PhD of the Faculty of Social and Behavioral Sciences at Leiden University and the Evolutionary Ecology Group at Antwerp University.

In this article, Tokdemir & Klein examine the strategic actions of governments against domestic terrorist groups and domestic terrorist groups’ reactions to such actions.

A new publication that brings together perspectives on language contact phenomena across temporal and spatial dimensions.

The outbreaks of AIDS and COVID-19 showed clearly how infectious viruses can influence people’s lives. Investigating the changes in the host metabolism may provide a paradigm shift to consider immune-metabolic interactions as therapeutic targets.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

We examine how soil inoculation influences aboveground organisms (i) directly, and indirectly via (ii) its effects on plant chemistry or volatile emission, or via (iii) mediating the effects of belowground pathogens on aboveground organisms via the shared plant.

In order to analyze the challenges linked to data use in the context of nexus governance, Giest & Mukherjee use a policy design lens and more specifically the perspective of organizational policy instruments to look at the Mediterranean region.

What is Interaction between Legal Systems (ILS) and what does it entail as research profile area at Leiden Law School? More on this at the kick-off event of ILS 2.0. This will take place on Wednesday 26 October 15.00 – 17.00 in the Grotiuszaal (A051 KOG). The afternoon will be closed with drinks at…

Can we build a biosensor to detect neuroblastoma markers in urine using the chemotaxis system in E. coli?

Curved single crystals provide variable, but well-defined surface structures.
