Public sector decision-makers operate amidst an abundance of information and unclear political objectives. Attention is the sine qua non of policy-making: What is attended to can be addressed in policy responses; what is overlooked or goes unnoticed cannot. Despite its importance, public administration…

The specialisation consists of a core course in political theory, a methods course, and several optional modules, including political theory options on themes such as Contemporary Theories of Justice, Human Rights Theory, Borders and Migration, and Environmental Ethics.

Religions involve belief in the unbelievable: in evil spirits causing disease, in souls surviving death, and in gods punishing wrongdoers and blessing the just. Cognitive studies suggest that humans are predisposed to speculate about fate and divine agency, but support from so-called ‘plausibility structures’…

LCCP is envisaged as an open space for stimulating discussion, critical debate and inventive co-operation in the Dutch philosophical community. It does not pursue a specific agenda but welcomes different readings of our shared philosophical situation, because it believes that deeper understanding is…

In this thesis we will explore the use of fuzzy systems theory for applications in bioinformatics.

The focus of the dissertation

The Master Honours Classes & Challenges are part of Leiden’s honours education for master’s students. While the Honours Academy is responsible for the practical organisation, the education is coordinated by teachers of all faculties.

The starting hypothesis of the project is that secrecy is not always inimical to democratic governance as conventional wisdom has it.

The philosopher and psychologist G.F. Stout was the teacher of Moore and Russell around 1894. This book shows that Stout's ideas have played a role in Moore and Russell's development from their early idealism towards analytic realism, where Stout's ideas often find their origin in early phenomenolog…

The two-year Foundations of Computing programme (120 EC) includes mandatory core courses and electives, as well as a Master's Thesis Research Project.

This is an Erasmus+ International Credit Mobility project of the Faculty of Science with Sichuan University in Chengdu.

Research in the POD-group addresses all features of random phenomena – modelling, structuring, analysis, control, optimisation – and covers both fundamental and applied aspects.

The objective of the Social and Organisational specialisation is to equip students with advanced training in research methods and professional skills that prepare them both for a career involving psychological research as well as for the application of scientific knowledge and methods in various professional…

The aims of the project are to: further clarify 'inhibition by safety'; explore and describe all possible sagety factors, with a special focus on the primary human safety source: social connectedness; reviewing prolonged stress responses without stressors.

Day-to-day activities are important in the development of social identities, the establishment of social standing, and the communal understanding of societal rules. This perspective is broadly referred to as practice theory and relates to the power of an overarching social structure and the individual…

Managing scarcity to serve the public interest is a classic government task. An important way to execute this task is by allocating individual rights that are only available in limited quantities, such as CO2 emission allowances, gambling licences, subsidies, radio frequencies, public contracts and…

The precise psychobiological mechanisms leading to chronic physiological stress responses have not been sufficiently explained, although stress is a major risk factor for disease and early death. A problem for conventional stress theory is that most of these responses seem to occur in situations without…

Master Honours Classes & Challenges particularly feature small group sizes, innovative teaching methods and an interdisciplinary approach. Students from all faculties combine their knowledge and are challenged to think outside the box. The courses are aimed at tackling complex issues and making an i…

The aim of this research was to establish if Ebeling's semiotactic theory and method of semiotactic analysis, as described in his works Syntax and Semantics (1978), Een Inleiding tot de Syntaxis (1994) and Semiotaxis, over Theoretische en Nederlandse Syntaxis (2006), could be applied to Modern Japanese…
