A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

Context-based learning has been implemented in secondary chemistry education. Hans Vogelzang, PhD at ICLON, reseached whether Scrum methodology might support creating context-based lessons. Scrum appears to be beneficial to learning outcomes. Defence on 10 November.

What does site patterning reveal about the social landscape dynamics across the historical divide?

How can educators in non-STEM fields integrate Climate Change Education to enhance students’ knowledge, skills, and resilience?

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.

On Thursday 9 november, Reijer Passchier defended his dissertation 'Informal constitutional change'. His supervisor is Professor Wim Voermans.

Take a view on the slides of the presentation and read what the event of Climate Change & Health was about.

The world we live in is changing in many aspects at an ever-increasing speed. And it will continue to do so. How do we anticipate these changes, such as the increase in atmospheric CO2, the extinction of species and industrialisation?

Jaroslaw Kantorowicz examines how strategic climate litigation influences public attitudes on climate policy, using a UK experiment to explore legal cues.

To what extent and how do identity processes influence health behavior?

The Indonesian Experience after the Fall of Suharto

This article describes the creation of an app that can help raise climate awareness and the action globally.

It is difficult to deny the value and importance of human rights, and yet their application in the context of climate change is increasingly contested. While some argue that it is difficult to establish the violation of human rights by climate change processes, others contend that human rights are anthropocentric,…

This part entails the analysis of an extensive sample of animal bone (c. 30,000 pieces) retrieved from well-defined archaeological contexts of the early period at Tell Sabi Abyad, c. 6800-6200 BC. It comprises aspects of taphonomy, ageing and osteometry, the reconstruction of the local spectrum of domestic…

Explaining cutback management strategies in public sector organisations: change leadership in times of crisis. How does the publicness of organisations affect the choice and implementation of cutback management strategies?

On the 13th of October, Cesko Voeten successfully defended a doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Cesko on this achievement!

Terrorism destabilizes governments, undermines civil society, threatens social and economic development, endangers democracy, and directly impacts human rights. The extraordinary events on 9/11 turned counterterrorism into a global governance project. The global collaboration is unprecedented with traditional…

This socio-legal study focuses on the implementation of climate change response laws and policies in developing countries with a weak rule-of-law environment, and their (unforeseen) effects on vulnerable peoples’ land rights.

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…

This work describes the use of click-to-release chemistry to get spatiotemporal control over immunocytokine activity. Until now, immunocytokines (cytokines coupled to a tumor-targeting-moiety) remained active throughout the body, being able to bind their respective receptors, causing mild to severe…

Religion is everywhere. Knowledge of religion is essential for anyone who wants to understand the world. If you are fascinated by the diversity of religions, their development throughout history and their meaning today – both in people’s personal lives and in society – the minor Religion in a Changing…

As every academic year, the leadership team of the Young Academy Leiden is changing. As of September 2021, Dr. Annemarie Samuels (Associate Professor, Social and Behavioural Sciences), former Vice-Chair, will be the Chair of YAL. And Dr. Sarah Giest (Assistant Professor, Governance and Global Affairs)…

This project aims to identify, quantify and map the exposure of Dutch national monuments to four climate change effects: flooding, waterlogging, drought and heat.

Promotor: Prof.dr. M.K. Richardson, Co-Promotor: F. Witte

Evaluating the environmental consequences of diet changes in the European Union.

By placing food at the centre of investigation, this Minor explores current-day debates on political, environmental, economic and cultural change at both the local and global levels.

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

How does the vision of problems and solutions from

Agriculture is among the most vulnerable sectors to climate change and poorer countries face the most severe difficulties. Coffee farmers in Central America, for instance, are facing multiple and mutually reinforcing crises, including price shocks, outbreaks of pests and diseases, migration, and farm…

How might we include circularity into the models often used in IPCC reporting (in technical language, how can IAMs, dMFA models and CGE models be integrated?) What are possible futures for global resource use and what are the consequences for greenhouse gas emissions in these scenarios?

The challenge is considerable, but so is the satisfaction when it succeeds: creating complex sugar molecules that play a role in biology.

Two excellent young chemists, Jeroen Codée and Sander van Kasteren, have received an ECHO grant for €260,000 from the Netherlands Organisation for Scientific Research (NWO). This funding will allow them to begin their research projects.

With defending his thesis ‘Applications of topology to Weyl semimetals and quantum computing’, the Leiden theoretical physicist Tom O'Brien has gained the rare 'cum laude' qualification. The freshly minted PhD has started a five year research programme on quantum algorithms for quantum chemistry, funded…

While there is a general consensus on the need for climate action among elites and the public, the public overall willingness to pay for such efforts is much lower.

An international team of laboratory astrophysicists and astrochemical modellers has shown that glycine, the simplest amino acid and an important building block of life, can form under the harsh conditions that govern chemistry in space. The results have been published this week in Nature Astronomy and…

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…

Description of 20th century changes in the Dutch flora: Description and interpretation (1999 - 2005)

Researchers from the Institute of Public Administration study the mechanism of lobbying and influencing political parties and the behaviour of these parties to see how solutions are found to problems. This enables them to reach conclusions as to how best to effect changes in political focus and poli…
