The legal regulation of political parties in post-war Europe.

The level of congruence between parties and their voters can vary greatly from one policy issue to another, which raises questions regarding the effectiveness of political representation. We seek to explain variation in party–voter congruence across issues and parties.

Many internal and external parties are involved in the expansion of the Gorlaeus Building.

How did parties as political organizations emerge?

The parliamentary elections in the Netherlands, scheduled for March 2017, are likely to result in a fragmented parliament and a complicated coalition formation process, according to Dutch political scientist Hans Vollaard (Leiden University).

This book analyses the emergence of modern parties in nineteenth-century Europe and explores their connection with the slowly developing institution of democracy.

Do political parties still perform their representational function? This is one of the main questions facing modern democracy. You will be addressing this issue both theoretically and empirically.

There are strict conditions relating to work for third parties.

The thesis addresses the long-term dynamical evolution of hierarchical multiple systems.

The Centre for the Study of Political Parties and Representation (CSPPR) is an interdisciplinary platform for scholars of Leiden University focusing on the historical and contemporary operation and functioning of political parties, with a particular emphasis on the causes and consequences of the changing…

This book concentrates on the regulation of political parties in the EU post-communist democracies, and on Bulgaria, Croatia, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia, Slovenia and Romania, in particular.

The Computer Systems, Imagery & media (CSI) research programme performs research on methods and techniques for the design, implementation and application of advanced computer systems, in particular parallel, distributed and embedded computer systems.

Beyond the immediately visible plenum, parliaments are highly complex institutions. They work through various venues in which decisions are prepared or even taken. The two main institutions in this regard are parliamentary party groups, which comprise legislators who are elected under the same party…

The Centre for the Study of Political Parties and Representation (CSPPR) aims to serve as an interdisciplinary platform for scholars of Leiden University for research focusing on the historical and contemporary operation and functioning of political parties and political representation, with a particular…

In this paper, Kantorowicz argues that reverse party favoritism exists. He exploits the fact that during the SARS-CoV-2 pandemic crisis, the Polish government was keen to launch postal voting in the presidential elections scheduled for May 2020.

How many written parliamentary questions does each party put to each minister? Political scientists Simon Otjes (University of Groningen) and Tom Louwerse (Leiden University) studied the practice in Dutch parliament and found that parties use parliamentary questions strategically as part of their ‘permanent…

What are the functions of the endocannabinoid system?

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

Slavoj Žižek is one of the most prominent public intellectuals of the left. His central claim holds that “today, it is more crucial than ever to continue to question the very foundations of capitalism as a global system”.

The Systems Pharmacology group is headed by Prof. Piet Hein van der Graaf. Systems Pharmacology is the quantitative analysis of the dynamic interactions between drugs and a biological system to understand the behaviour of the system as a whole, as opposed to the behaviour of its individual constituents;…

In modern information systems, a large number of different components are often active simultaneously. This phenomenon - known as concurrency - underlies not only the functioning of computer systems but of any system in which many processes take place at the same time.

Lecture

The aim of the research programme Systems Pharmacology lies in the development of personalised medicine strategies, and development of new systems-based approaches in translational and clinical pharmacology.

Here are some systems and infrastructures that are useful to students.

Systems are called real-time systems, if the correctness of the system does not only depend on the correctness of the system output but also on whether the output is delivered on time.

Adenosine is an endogenous ligand which exerts its action by activating adenosine receptors (ARs), while its circulating levels are controlled via a variety of mechanism and proteins, amongst others the equilibrative nucleoside transporters (ENTs).

Lecture

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…

The Institute of Environmental Sciences has carried out and participates in several projects that deal with the analysis of energy systems.

What drives the restrictiveness of immigration reforms? Political scientists Katharina Natter (Leiden University), Mathias Czaika (Danube University Krems) and Hein de Haas (University of Amsterdam) analysed immigration reforms in 21 Western immigration countries between 1970 and 2012. They found that…
