Sentencing is becoming increasingly complex for the courts. Legal scholars and criminologists from Leiden document the process of sentencing in the Netherlands. They use this knowledge to advise legislators and those who implement this legislation on how to make sentencing more consistent and effect…

Edited by linguists Jenny Audring (Leiden University) and Francesca Masini (University of Bologna), this is a unique handbook with a focus on morphology theories rather than morphological data. It covers a wide array of morphological theories, from traditional twentieth century models to current theoretical…

Practical applications for the reconstruction of the past

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.

The Darién region of Panama is the only land bridge connecting North, Central and South America. Nowadays home to descendants of African enslaved peoples, Indigenous peoples (Emberá, Wounaan, and Guna), and mestizos, Darién has been and still is fundamental to connectivity, cultural interchange, and…

Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

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.

Százhalombatta-Földvar is a Bronze Age fortified tell settlement on the right bank of the river Danube, 30 km south of Budapest in Hungary. It is one of the best preserved temperate climate tells in Europe and well-known for the extraordinarily rich data it produces. Since 2014 Leiden students are welcomed…

On 12 May, GTGC Deputy Coordinator Valentina Carraro presented her work during the symposium “EU Crises: Rethinking European integration theories” at Maastricht University. The symposium was organised as part of the farewell event for the retirement of Prof. Tannelie Blom.

This political theory specialisation focuses on the concepts of legitimacy and justice—political philosophy’s core themes. Immersing yourself in theories, philosophical and theoretical methods, and complex cases, you will make the leap from opinion to analysis.

Imitation is, perhaps more than ever, constitutive of human originality.

The master in Cultural Analysis: Literature and Theory at Leiden University focuses on the study of literature from a comparative and theoretical perspective, with a special emphasis on literary movements and genres of the 19th, 20th, and 21st centuries. It covers a wide range of languages and cultures…

'Politics of Withdrawal' considers the significance of practices and theories of withdrawal for radical thinking today.

This six-weeks online course delves into the research behind terrorism as it unpacks the assumptions and impacts of both terrorism and counterterrorism.

The Summer School on International Humanitarian Law is designed by the Grotius Centre Kalshoven-Gieskes Forum on International Humanitarian Law. Application is now open!

A cultural sequence of western coastal French Guiana from 5000 BP to present

Sufyan Al Karaimeh, a guest researcher at the Faculty of Archaeology, is currently involved in the Aerial Archaeology in Jordan (AAJ) Project. Over the past 25 years, the individuals involved in this project have not only compiled an expansive collection of photographs but have also helped discover…

We study the structure, dynamics and physics of complex networks emerging from the intricate interconnectedness of the constituents of large systems.

The terms ‘social’ , ‘collective’ or ‘public’ memory, are often contrasted with ‘private’, ‘individual’ or ‘personal’ memory. All these terms derive from a fairly new and interdisciplinary scholarly field that is often referred to as ‘memory studies’, and that according to some critics has developed…

On the 28th of September Go Hirasawa successfully defended a doctoral thesis and graduated.

This study looks at the question of how and at what level students in primary teacher education can integrate theory and practice, and how the organisation of their learning environment, focusing especially on mathematics and pedagogy, can contribute to that.

Is there a causal mechanism underlying the decision to attack another country when on the brink of war? If so, does this mechanism differ between regime-types? Political scientist Femke Bakker (Leiden University) addresses this question from a political psychological and comparative perspective and…

The focus of our theoretical research is understanding the behaviour of soft condensed matter, physical matter which is deformed or structurally altered by thermal fluctuations or small stresses.

Direct radiocarbon dating of human remains is crucial for the accurate interpretation of prehistory. Yet given the scarcity of prehistoric human remains, direct dating is often too destructive for important fossils. The reduction of sample size necessary for dating bone is therefore of great interest…

In this work we describe three methods to improve the performance of Quantum Field Theory calculations.

The goal of the ANASTASIS project is the analysis and publication of early medieval (Merovingian) cemeteries in the Netherlands (c. 500 – 750 AD).

The linguistic project constitutes the connection between the two other subprojects. It consists of two parts.

Organized by the Grotius Centre for International Legal Studies, this programme enables students and professionals from all over the world to engage in discussions on the prospects and challenges of international criminal justice. Application is now open!

On 16 april 2020, Andrew Fink defended his thesis 'The Importance of Conspiracy Theory in Extremist Ideology and Propaganda'. The doctoral research was supervised by Prof. A. Ellian.

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

Following their application to system biological models, control theory techniques have further potential to aid in the understanding and application of quantitative systems pharmacology models.

The next generation of high-contrast imaging instruments on space-based observatories requires sophisticated wavefront sensing and control in addition to a high-performance coronagraph.

While self-driving cars and autonomous weapon systems have received a great deal of attention in media and research, the general requirements of ethical life in today’s digitalizing reality have not been made sufficiently visible and evaluable.

The relevance of intentionality to the interpretation of Aristotle was first suggested by Brentano in his Psychology from an Empirical Standpoint. Here we take our starting point from Brentano and investigate how Brentano’s concept of intentionality is rooted in Aristotle.

This Thesis shows discoveries in non-linear astrochemical kinetics as well as a deeper analysis of dark clouds chemistry.

The book offers different theoretical perspectives to help examine the process of public sector reform. In addition it gives an overview of the major trends in the core areas of the functioning of the public sector.

Professor of Archaeometry Patrick Degryse analyses archaeological finds using techniques from chemistry, physics and biology. He will give his inaugural lecture on 19 February. He reflects on three interesting propositions from his lecture.

Generally the data from remote sensing surveys - the scanning of the earth by satellite or aircraft in order to obtain information about it - is screened manually in archaeology. However, constant monitoring of the earth's surface causes a huge influx of data of high complexity and high quality. To…

Caribbean archaeological heritage is threatened by natural impacts but also increasingly by economic developments, often resulting from the tourist industry. The continuous construction of specific projects for tourists, accompanied by illegal practices such as looting and sand mining, have major impacts…

Fascism tends to be relegated to a dark chapter of European history, but what if new forms of fascism are currently returning to the forefront of the political scene?

This thesis is is made of three parts. The first part describes a generalization of the Chabauty's method, that can be used to determine the rational points of a curve such that s+g>r+1, where g is the genusof the curve, r is the rank of the Mordell-Weil group of the jacobian of the curve and s is…
