In 1989 the Board of Governors and the Council of Leiden University granted the establishment of a special Chair for Central European Studies with a focus on Austria: 'Lehrstuhl für mitteleuropäische Studien mit besonderer Berücksichtigung Österreichs'.

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

The making of sacrifices seems part and parcel of any elite sportsperson’s life. Remarkably, the insights that we find in the current literature in social sport studies are not able to make sense of the references to sacrifice in the data that emerged in the context of this study on the social significance…

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

What makes a good historian? When historians raise this question, as they have done for centuries, they often do so to highlight that certain personal attitudes or dispositions are indispensable or studying the past. Yet their vieuws on what virtues, skills or competencies historians need most differ…

Can we predict fluctuations in suicidal ideation in a person’s daily life, from hour to hour?

The ARTIVES project studies imaginaries of diversity portrayed by artists in Lisbon and Rotterdam in their films, performances and (oral) literature with the aim to explore their transgressive potential of opening up possibilities of thinking differently about migration-related diversity. Their stories…

The project seeks to explore the interplay of valuation and inequalities in science, using the interdisciplinary and planet-critical field of forest research as empirical case. It examines which/whose knowledge is recognised on what grounds, and how social dimensions like gender and geographical location…

Where are the Women in Global Governance and in peace processes?

On 2 September 2022, 300 students received their Bachelor Diploma of International Studies. The students were awarded their diplomas in the historic Pieterskerk in Leiden, in front of a large audience of family and friends. With about 1000 people present, including the graduates, the International Studies…

This thesis describes a study from both a theoreticaL and an experimental point of view.

In recent years, the use of primary data in terrorism research has increased. In order to maximise the benefits of this trend, we want to encourage terrorism scholars to implement open science practices more systematically. This article therefore presents different avenues towards open and reproducible…

In this article, Lianne Visser contributed to the understanding of why collaborative governance is a challenging response to wicked problems.

As part of Nexus 1492 Subproject 4: A Future for Diverse Caribbean Heritages, which seeks to shed light on how local communities interpret and engage with heritage in the present day, this doctoral study aims to gain insight into how indigenous heritage is represented in the school curriculum for social…

In this thesis, I study 1) metabolic alterations in tuberculosis related to wasting syndrome in human patients as well as in rodent and fish animal models. 2) effects of the mutation of the leptin gene on cachexia and diabetes in rodent and zebrafish animal models.

On 19 September 2019, Lynette Janssen defended her thesis 'EU Bank Resolution Framework: A comparative study on the relation with national private law'. The doctoral research was supervised by Prof.mr. W.A.K. Rank and prof. M. Haentjens.

Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

The stratum corneum is the outermost skin layer and consists of dead cells embedded in a lipid matrix.

A difficulty of studies on chemical kinetics are the reaction time scales and detection of their intermediates.

In the studies described in this study, we introduce a novel ex vivo human skin barrier repair model. To develop this, we removed the upper layer of the skin, the stratum corneum (SC) by a reproducible cyanoacrylate stripping technique.

Organised in four separate sessions throughout the day, and broadcast live online to guests and families who could not join, a total of 260 students received their Bachelor’s Diploma of International Studies on 28 August 2020 at the graduation ceremony in the historic Pieterskerk in Leiden.

The subjects of the texts vary from Demosthenes to the delivery of camels in early Islamic Egypt, and their provenances stretch from the Eastern to the Western Desert, and from the Egyptian Nile valley to Qasr Ibrim in northern Nubia.

Islam at 250: Studies in Memory of G.H.A. Juynboll is a collection of original articles on the state of Islamic sciences and Arabic culture in the early phases of their crystallization.

What does the daily life of those who travelled to Syria to join jihadist groups look like? Destination Syria, a new ISGA report, provides answers to this question

On 10 June 2021, Merinda Stewart defended her thesis 'Freedom of Overflight: A Study of Coastal State Jurisdiction in International Airspace'. The doctoral research was supervised by Prof. P.M.J. Mendes de Leon en Prof. J.J. Rijpma.

Migration is the talk of the town. On the whole, however, the current situation is seen as resulting from unique political upheavals. Such a-historical interpretations ignore the fact that migration is a fundamental phenomenon in human societies from the beginning and plays a crucial role in the cultural,…

This paper describes two synthetic lipid models designed to replace human stratum corneum (SC) in studies of the impact of volatile organic chemicals on the molecular organization of the skin barrier lipids.

What is the role of emotion regulation in coping with interpersonal feedback?

The main aim of my Ph.D. thesis is to further explore the value of using early developing zebrafish larvae (up to 5 dpf) as a model to study anxiety-like behaviour and their pharmacological modulation with drugs.

Structure-affinity relationship (SAR) and structure-kinetics relationship (SKR) studies were combined to investigate a series of biphenyl anthranilic acid agonists for the HCA2 receptor.

This dissertation provides an up to date description of the Indo European lexical stock of Armenian (ca. 500 entries) with systematic inclusion of unused data that are found in Armenian dialects.

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

The endocannabinoid receptors CB1R and CB2R are involved in a plethora of processes, and consequently are involved in many pathological conditions. Their wide distribution makes the CBRs both an interesting therapeutic target and hard to study.

A central and much debated topic in the study of language acquisition concerns the nature of the learning mechanisms that are required. Are the computational and learning mechanisms that guide learning about language structure special and specific to language or humans?
