Having a chronic somatic condition can result in a variety of impairments in patients’ daily lives, including not only physical complaints such as pain, itch, and fatigue, but also problems of negative mood and impairments in social relationships. Next to disease characteristics, individual difference…

The miniaturization of machines towards the micron and nanoscale requires the development of joint-like elements that enable and constrain motion. We developed a facile method to create colloidal joints, that is, anisotropic colloidal particles functionalized with surface mobile DNA linkers that control…

This PhD project analyses the politics and aesthetics of depictions of torture in American and European ‘war on terror’ films.

People are less willing to give up an interest when in a negotiation situation than when they can do it of their own free will, as Leiden University psychologist Eric van Dijk discovered. Knowledge of this kind can be used by policy makers, for instance, to motivate people to adopt certain desirable…

Chapter 2 describes a post-synthetic methodology to introduce a fluorescent label in highly lipophilic, Pam3Cys based conjugates.

We are all aware of the importance of a healthy lifestyle. However, at the same time we also experience many difficulties when we are trying to change our behavior to become more healthy. For example, more often than not our good intentions to exercise more or to eat fewer unhealthy snacks fail miserably…

Understanding individual differences in self-regulation in boys with ODD/CD on the level of brain, cognition and behavior

Larissa Mendoza Straffon and colleagues investigated visual attentional biases toward self-made artworks, which tend to be favoured, remembered, valued, and ranked above and beyond objects that are not related to the self. Their findings confirm that attention and preference are higher for self-made…

Language learners in higher education increasingly conduct out-of-class self-directed learning facilitated by mobile technology. This project aims to explore how university students use mobile technology for their self-directed language learning and investigate factors that influence their self-directed…

Political scientist Maurits de Jongh (Leiden University/Sciences Po) argues that political liberalism is self-defeating as a framework of justification for liberal conceptions of justice. He explores how the framework's self-imposed criterion of acceptability in the eyes of all reasonable citizens leads…

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

To what extent and in what manner can experimental video be used to reclaim the capacity for telling one’s own story, on one's own terms, speaking in tongues outside the linguistic framework of immune system discourse?

Research in the Daniela Kraft Lab focuses on self-assembly in biological and soft matter systems, ranging from anisotropic colloidal particles to lipid membranes, emulsions, and viruses.

Self-censorship violates principles of a free society but few people want to take the role of the martyr.

The topic of this PhD thesis is teachers' perspectives on self-regulated learning.

How did British scholars and scientists in the period of discipline formation envision, experience and resist scholarly temptations?

Intelligent machines are going to make ethical decisions too. Should a self-driving car be allowed to slam into pedestrians to save its passengers from a head-on collision? Should a negotiation app be able to detect stress in your opponent’s voice? And who makes these decisions: the user, the system’s…

Why did 'character', 'habit', and 'virtue' serve as key terms in late 19th and early 20th-century scholarly correspondences, biographies, and obituaries? Why did scholars around 1900 display so much interest in the working habits and character traits of what they called the 'scholarly self'?

In online games conflicts between players may arise. Novin, Bos, Stevenson and Rieffe investigated factors that may explain why some adolescents react more angrily than others in this type of situation. In their realistically designed gaming environment, the (pre-programmed) fellow player suddenly started…

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.

Optimization tasks in practice have multifaceted challenges as they are often black box, subject to multiple equality and inequality constraints and expensive to evaluate.

Taking as a point of departure the Italian American community in Boston and its process of collective remembrance surrounding Saint Anthony’s Feast, we address the limits and potential of montage.

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.

It is estimated that approximately 30% of all proteins require a metal to function. Investigating the relationship between metal-binding and peptide/protein folding allows us to uncover fundamental rules for creating metallo-peptides and proteins, which in turn leads to the creation of new structures,…

This study examines the system and poetics of literary patronage in the Renaissance by presenting a comprehensive analysis of the poetry of Giannantonio Campano. In this way, it addresses two themes largely overlooked by modern scholarship.

The more complex the object, the harder it is to fold up. Space satellites often need many small motors to fold up an instrument, and people have difficulty simply folding up a roadmap. Physicists from Leiden and Amsterdam have now designed a structure that folds itself up in several steps. Publication…
