This project, under the supervision of Prof. Dr. Hans van der Plicht, comprises several studies aimed at the use of isotopes occurring naturally in organic material as tracers for both the climate change and its cultural impact at about 6200 BC. The research will be carried out by the co-applicant at…

Climate Proofing Industrial Estates: Entrepreneurs’s Participation in the City of Leiden

Climate Proofing the Neighbourhood: Evaluating Citizen’s Participation in the City of Leiden

What is the optimal design of sandy solutions for sustainable climate change adaption, from an ecological, biophysical and societal point of view?

This part of the research programme is carried out by Prof. Dr. René Cappers. It focusses on the continuities and changes in the use of plants at Late Neolithic Tell Sabi Abyad, as well as on their implications as proxy evidence for the climate change c. 6200 BC. Parallel to the design of the other…

The use of increasingly large and diverse datasets to guide urban climate action has implications for how, and by whom, local governments are held accountable.

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

Which traits did change due to the invasion process of plants and how do these traits contribute to the invasiveness of such species. What is the role of carbohydrate accumulation? What is the function of carbohydrate accumulation in plants? Is genetic variation depleted in invasive species under se…

This abrupt climate change of 8200 years ago (the so-called 8.2k calBP climate event) has received wide attention among natural scientists, also because of today's rapid climate changes and their impact on our own society. The archaeological implications, however, have not been investigated so far.…

This thesis describes the use of the evolutionary approach in the study of language change, aiming to provide a better insight in the mechanisms that play a role in language change and to validate this approach in the field of language change.

This paper describes two synthetic lipid models designed to replace human stratum corneum (SC) in studies of the impact of volatile organic chemicals on the molecular organization of the skin barrier lipids.

Development of scenarios for 2050 detailed in an IO framework

Climate change is a hot topic and constantly in the news. Thousands of Dutch high school students protested at the Malieveld in The Hague. News website Nu.nl has barred climate change deniers from their comments section to prevent ‘fake news’. How does climate change impact the research community, and…

We are developing the conceptual framework, which is new to this taxonomic group, and evaluate the current state of the art with respect to all critical parameters and transfer functions for a fully developed Population Consequences of Acoustic Disturbance (PCAD) model.

With our research and teaching, we help make the world a better place. We join in the academic and public debate, and seek answers to economic and social issues – not just at the local and regional level but at the global one too.

The project Deconstructing Stability aims to improve reconstructions of late prehistoric landscapes and predictive models for the purpose of archaeological heritage management.

A new study in Nature Plants has explored the most important organising principles that control vegetation behaviour. The insights from this study can be used to improve predictions on climate change. Leiden scientists Peter van Bodegom and Nadia Soudzilovskaia participated in the study.

Earlier this year, the public voted environmental scientist Paul Behrens Discoverer of the Year 2018. Behrens is an interdisciplinary scientist who wants to understand our impact on the planet. ‘Unfortunately, we are not doing enough. Huge changes are underway and we’re running out of time to avoid…

Leiden Law School at the heart of society

Can the (industrial) herbal extraction process be mathematically described and can this model be used to optimize the extraction in terms of quality and economical parameters?

With our research and teaching, we help make the world a better place. We join in the academic and public debate, and seek answers to economic and social issues – not just at the local and regional level but at the global one too.

Using the principles of Industrial Ecology in Environmental Policy making in two cases: transition to a hydrogen economy and chlorinated compounds.

We describe certain birational modifications of nodal relative curves over a regular base of arbitrary dimension.

We strive to address the challenge of constructing a modeling language to write software which can take advantage of recent hardware developments (multicore, cloud) without compromising in its abstraction levels.

On the 23rd of September, George Saad successfully defended a doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates George on this achievement!

As most of you are well aware of, Climate Change has been an ongoing and pressing topic, and therefore deserves our close attention. What and how exactly happens during Climate Change? What are the effects of it? AND possibly most importantly, what can WE as students do about it?

How can we develop and further improve life cycle impact assessment methods, characterisation factors and normalisation factors?

Environmental researcher Paul Behrens generated both international as national media attention with his recent publication in Nature Energy. The media included Science Daily, Quartz and the Dutch financial newspaper Financieel Dagblad. In his publication, Behrens warns for possible power disruptions…

Existing work in probabilistic language modeling can be mostly divided into two categories: (i) Purely sequential, string-level approaches ensure fluency at the local level without notion of grammaticality and seek improvements in the use of massive training corpora. (ii) Fully structural, tree-based…
