Dimensions of Free Speech: An Exploration of a New Theoretical Framework
In ‘Dimensions of Free Speech’, Devrim Kabasakal Badamchi (Leiden University Institute of Political Science) offers a new theoretical framework for free speech by critically analysing the major justifications for free speech. Kabasakal Badamchi argues for a justification: namely the double-grounded…

Into the Darkness: Forging a Stable Path Through the Gravitational Landscape
In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

Pellikaan & Van Willigen, Bilateralism and Nuclear Security
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…

Enlightening the Primordial Dark Ages
This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

Global Fields and Their L-functions
Artin L-functions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.

Teachers’ practical knowledge and lesson design in the context of innovation
This project is situated within the context of an innovation of the biology curriculum in Dutch secondary schools. The main purposes are (1) to clarify the relation between teachers’ practical knowledge and the decisions they make when planning and implementing their lessons and (2) to develop a professional…

Mutable Audible – An Operative Ontology of the Sound Image
In his dissertation Gabriel Paiuk explores the variable ways in which what is heard is formed. To address this, he postulates a novel concept of sound image in a post-anthropocentric context in which both mind and material artefacts are instances across which the image occurs, rather than hosts on which…
