The Leiden LIS Sectoral Income Inequality Dataset, assembled by Chen Wang, Stefan Thewissen and Olaf van Vliet (Version 1.1, March 2014), contains information on multiple indicators of earnings inequality and employment within 9 sectors and 12 subsectors, drawing upon micro data from Luxembourg Income…

The Collective Experience of Empathic Data Systems (CEEDs) consortium developed novel integrated technologies that support experiencing, analysing and understanding of very large datasets.

The unemployment replacement rate data set, assembled by Olaf Van Vliet & Koen Caminada (version 1, January 2012), provides data on unemployment benefit schemes in 34 welfare states from the 1970s until 2009. The current data set includes all 27 member states of the European Union and 7 non-EU OECD…

Leiden LIS Budget Incidence Fiscal Redistribution Dataset on Income Inequality (2017), assembled by Jinxian Wang and Koen Caminada (Version 1, November 2017), presents the disentanglement of income inequality and the redistributive effect of social transfers and income taxes in 47 LIS countries for…

Political scientists Tom Louwerse, Simon Otjes & Cynthia van Vonno introduce the Dutch Parliamentary Behaviour Dataset, a record of parliamentary (voting) behaviour in the Dutch Tweede Kamer (Second Chamber, House of Representatives) since 1945.

The Social Assistance and Minimum Income Levels and Replacement Rates Dataset, assembled by Jinxian Wang and Olaf van Vliet (version December 2016), provides data on minimum income benefit schemes in 33 countries from 1990 until 2009.

Leiden LIS Budget Incidence Fiscal Redistribution Dataset on Relative Income Poverty Rates (2019), assembled by Koen Caminada and Jinxian Wang (Version 1, February 2019), presents the disentanglement of relative income poverty measurers and the anti-poverty effects of social transfers and income taxes…

For many system in statistical physics the microcanonical and canonical ensemble are equivalent in the thermodynamic limit, but not for all.

This thesis seeks to combine two different research topics; Multi-Objective Optimization and Complex Network Analysis.

What invertebrates are available to feed nestlings in an agricultural landscape of varied complexity?

The goal of the project is the development of stream mining techniques for complex patterns such as graphs. We will try to extend the existing state-of-the-art techniques into two, orthogonal directions: on the one hand, the mining of more complex patterns in streams, such as sequential patterns and…

In photoactivated chemotherapy (PACT), a biologically active compound is caged by a light-cleavable protecting group.

The Leiden Complex Networks Network (LCN2) aims at bringing together scientists from different disciplines, based on a common interest in both theoretical models and empirical analyses of networks and graphs.

This thesis describes the genetic and prokaryotic diversity of giant barrel sponges.

We study the physics of a broad range of biological and soft materials

The complexity of an intelligence problem determines to a great extent the certainty that can be provided by intelligence and security services.

Issues such as climate change, the depletion of natural resources or social inequality are too complex to be addressed from a single scientific discipline or by a single country. Leiden University has the expertise to bring the resolution of these enormous problems a small step closer.

In this thesis, we extend the concept of null models as canonical ensembles of multi-graphs with given constraints and present new metrics able to characterize real-world layered systems based on their correlation patterns.

From surface science towards industrial practice using high-pressure scanning tunneling microscopy.

In vitro disease models play a fundamental role in drug research. They enable the systemic identification and validation of disease mechanisms and the discovery of possible drug targets. However, more than often, drug candidates that are identified in vitro fail in the later clinical stages of drug…

The aim of this project is to determine in which cases uncertainty statements resulting from a Bayesian statistical analysis can be trusted.

Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

In this dissertation, the synthesis and characterization of a series of iron complexes based on different ligand platforms are described.

Complex systems can be characterized as systems in which multiple components interact with each other, often in non-linear ways. The main goal of this research will be to investigate if and how the international tax system can be defined and modelled as a complex system. Approaching the international…

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.
