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…

Research in and through art is an inseparable part of the artistic or design practice of the researcher. Consequently, research-in-art (as opposed to research-about-art, such as art history) does not have a set goal or expected result, nor are there predetermined general procedures. The outcome of the…

The recent rise in global migration movements and the simultaneous attempts to prevent migrations to the Global North in general and Europe in particular have produced numerous images and narratives that try to record and convey these events and their actors.

In the first part of this thesis we study the geometry of folding patterns.

To what extent are the rights to street children violated en how can their rights be protected?

The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.

Understanding interactions in quantum many-body systems remains one of the most profound and difficult challenges in condensed matter physics.

Reducing greenhouse gas emissions is one of the most pressing challenges that humanity faces in the coming decades.

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.

This doctoral trajectory explores sound, its image and its role in relating humans and our technologies to the environment.

Where in the model of contemporary art, which can be described as a hybrid and joint undertaking between artists, institutions, curators, theory and discursivity, is the actual 'object' of art located and generated? Where and by whom and in what configuration of positions is it produced? Who or what…

From October 1-3, 2017, the 24th Annual International Law and Religion Symposium was held at Brigham Young University in Provo, Utah, USA.

Bruno Munari (1907–1998) was a prolific and influential artist, designer, and writer. Alessandro Colizzi’s study is the first extensive, detailed record of Munari’s graphic design production, and as such provides a substantial base for a full understanding of his oeuvre.

During the coronavirus years 2020 and 2021, Dutch citizens became poorer, more anxious, less free and more rebellious. The State gained more power and entered the lives of citizens in all manner of ways to protect their health. Only recently did the State give citizens their freedom back – in part.

Barbarism: from the 18th century to the present.

The subject of the research is ‘difference and repetition’, an area which bears a direct relationship to Wjm Kok’s practice, in which the production of work always emerges and passes through series.

Without academic freedom, we might not have antibiotics, nor a deep understanding of human behaviour. Literary criticism, climate models, and ecological restoration would be severely limited; just like ethical reflection on artificial intelligence, justice, trauma, parenting, faith and hope. All these…
