Computers are capable of making incredibly accurate predictions on the basis of machine learning. In other words, these computers can learn without intervention once they have been pre-programmed by humans. At LIACS, we explore and push the borders of what a revolutionary new generation of algorithms…

This book reveals how one publishing firm's editorial strategy helped to legitimate European colonialism in the early modern era.

The League of European Research Universities (LERU) calls for greater appreciation of fundamental research that does not have an immediate application. A working group headed by Geert de Snoo, dean of the Leiden Faculty of Science, issued a memorandum on the subject on 29 August.

European labour law has an unmistakable influence on national law. This applies even more to the case-law of the Court of Justice of the European Union (CJEU), as it has implications for the application of European law in the Member States and with it the interpretation of national law. Collected Cases…

The Vidi grant is for experienced researchers who have already spent several years doing postdoctoral research.

What are the typical characteristics of teaching at research universities, and how is excellence defined and promoted? These are the key questions in the latest position paper published by LERU, the partnership of European research universities, including Leiden.

The University of Copenhagen and Trinity College Dublin will become members of the League of European Research Universities (LERU) with effect from 1 January 2017. The LERU, of which Leiden University is one of the founders, aims to promote the interests of scientific research and teaching.

In this article, Madeleine Hosli, Professor of International Relations at the Institute of Security and Global Affairs, and Jaroslaw Kantorowicz, Assistant Professor at the Institute of Security and Global affairs, discusses the relevance of structural variables in a time where European politics are…

The topic of this PhD thesis is teachers' perspectives on self-regulated learning.

How is collaborative learning in teacher education designed and implemented? How do students experience those collaborative learning assignments? What aspects of the design and the implementation lead to which perceived learning outcomes?

Language learners in higher education increasingly conduct out-of-class self-directed learning facilitated by mobile technology. This project aims to explore how university students use mobile technology for their self-directed language learning and investigate factors that influence their self-directed…

This article 'Shaping the European External Action Service and its post-Lisbon crisis management structures: an assessment of the EU High Representatives’ political leadership' assesses the role, influence and core aspects of the EU High Representatives’ (HR/VPs) “political leadership” in the context…

The aim of this research project was to increase understanding of which collaborative learning approaches already exist in conservatoire education, and how implementation of collaborative learning could be supported.

In what way can teachers support and enlarge student engagement in a blended learning context?

How can the problems in establishing a sustainable common security and defence mechanism for the EU be explained?

This project aims to revisit the relationship between the European cultural agenda and the local identity formation process, and social and religious transformations of Arab Christian communities in Palestine, when the British ruled via the Mandate. What was the role of culture in European policies…

Whilst government’s ability to design ‘context-specific’ regional innovation policy is generally assumed to depend on the region’s decision-making power, the aim of this study is to investigate how regional government matters. In order to open up the black box of policy design, the study develops a…

This article studies the influence of framing on preferences for cooperation with the EU.

Madeleine O. Hosli & Jaroslaw Kantorowicz analyze EU states' foreign policy divergence at the UN General Debate, assessing if Lisbon Treaty reforms increased EU cohesion or if states maintain distinct positions.
