Criminal Justice as a concept refers to the system of practices and institutions of governments directed at upholding social control, deterring and mitigating crime, or sanctioning those who violate laws with criminal penalties and rehabilitation efforts. While the definition seems rather clear-cut,…

The goal of this book is to place architectural studies, in which people’s interactions with each other and material resources are key, at the crossing of both landscape studies and material culture studies, where it belongs.

This work represents the final results of several years of research within the Maya region. It deals with the relations between architecture and urbanism with landscape and astronomy.

In the one-year Linguistics specialisation programme you will be able to focus on a specific thematic or disciplinary route, reflecting the linguistics expertise present at Leiden University.

A master's degree in Psychology at Leiden University combines theoretical knowledge with academic and professional skills, making you an attractive candidate for many employers. However, there are far more graduates than vacancies, especially in mental health care, and competition is therefore fierc…

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.

The master’s programme Mathematics at Leiden University focuses on analysis, probability and statistics, number theory and (arithmetic) geometry. It offers five specialisations ranging from Applied Mathematics to Mathematics and Business Studies.

Alex Colling himself calls his bachelor's thesis ‘the highlight of his time in Leiden’. And according to his supervisors, that resulted in an outstanding thesis, with great attention to detail. The Mathematics and Physics student worked on a mathematical description of monopoles: hypothetical particles…

My PhD research is devoted to studies of the conjectural cluster-algebraic symmetry in the theory of topological string, which is the simplest, however already non-trivial sector in the theory of string.

With our research, we aim to enrich academic and practical knowledge on the governance of sustainability, as well as contribute to public debates on these issues. For that purpose, we strive for diversity in our research subjects, research methods and theoretical approaches. Our research covers different…

Anchoring Cultural Formation in the First Millennium BCE

Semantics and pragmatics are united in the study of linguistic meaning.

How does the cluster bootstrap procedure in combination with various types of linear models perform in the analysis of longitudinal data, compared to other methods.

Citizens, journalists and scholars notice that foreign policy in, and of, the European Union, is ‘de-Europeanising’. Political scientist Daniel Thomas (Leiden University) offers a theoretical exploration of the likely implications. He expects that it will become more difficult for the EU to achieve…

This inaugural lecture discusses the question: How to cooperate in the digital era?

This dissertation is a study of North Korean art as a site where politics, history, and culture meet.

Political scientists Huib Pellikaan and Niels van Willigen (Leiden University) use and elaborate on the theoretical insights from game theory in order to understand nuclear security in changing environment. Now that the relations between the US and Russia have deteriorated and smaller nuclear states…

The Death of Archaeological Theory, edited by John Bintliff and Mark Pearce, addresses the provocative subject of whether it is time to discount the burden of somewhat dogmatic theory and ideology that has built up over the last 25 years.

The Hague Journal of Diplomacy (HJD) is the world’s leading research journal for the study of diplomacy and was founded in 2005.

Biological polymers, including proteins and the genome, undergo folding processes crucial for their proper functioning. Even slight changes in the folding structure of these biopolymers can have significant implications, leading to the development of various pathological conditions, such as neurodegenerative…

Computational linguistics uses computational methods to help answer linguistics questions across a variety of topics.

Leiden University Centre for Linguistics (LUCL) is a reputable institute in the field of linguistics, offering excellent research and education opportunities covering a broad range of languages of the world.

This paper develops a novel theoretical framework for the conduct of postmortems after major foreign policy surprises for the European Union and its member states.

Harm reduction in practice: a comparative analysis of the Dutch and Brazilian approach towards drug users.

The focus of our theoretical physics research is the nature of macroscopic matter that is in one or the other way still in the grip of quantum physics.

Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

This engagingly written textbook provides a unique 'hands-on' introduction to sociolinguistics, which equips readers with the tools to start their own sociolinguistic research project.

The Golden Horde Project was initiated by Dr. Marie Favereau and Dr. Gabrielle van den Berg. The initiative is funded by Asian Modernities and Traditions (AMT) and Leiden Global Interactions (LGI) research profile areas.

Diplomatic Studies is a series with monographs and edited books, including contemporary, historical and future-oriented academic work. The series is receptive to a wide array of methodologies.

The Biodiversity and Sustainability consists of 120 European Credit Transfer System (EC) points and includes a theoretical part (30-60 EC) and and one or more research projects (60-90 EC).

The main theme of this thesis is the theoretical study of Gaussian processes as a tool in Bayesian nonparametric statistics.

The SCS courses train you in practical and theoretical aspects of science communication. Internships help you decide whether you want to choose a career in science communication or Mathematics research or a combination.

Through courses and research projects, you are trained by experts in the field.

You have ample opportunity to assemble your own study path in Cosmology. The courses cover the full spectrum from theoretical early universe to observational cosmology.

NESA offers a one-year teaching and training programme especially for upcoming and all first year PhD candidates, consisting of 5 masterclasses on current and trending theoretical debates in our discipline, an extensive methodology training and occasionally a cohort meeting off campus.

Can you imagine a radically different world? In our times dominated by neoliberal capitalism, we seem to lack not only viable alternatives, but also the capacity to envision anything outside of the status quo.

Does hegemony—legitimated rule by dominant power—have a role in ordering world politics of the twenty-first century? If so, what form does that hegemony take: does it lie with a leading state or with some other force? How does contemporary world hegemony operate: what tools does it use and what outcomes…
