Unconstrained day-to-day activities are difficult to quantify and how the corresponding movements shape the brain remain unclear. Here, we recorded all touchscreen smartphone interactions at a sub-second precision and show that the unconstrained day-to-day behavior captured on the phone reflects in…

To what extent and how do identity processes influence health behavior?

Are there any differences in gaze behavior between high and low socially anxious individuals? What factors influence the relation between social anxiety and gaze behavior?

Recent studies of Neandertal body mass and skin surface indicate raised energetic requirements in this lineage compared to anatomically modern humans.

Governing Cyberspace: Behavior, Power and Diplomacy is based on a selection of papers presented during The Hague Program for Cyber Norms' inaugural conference Novel Horizons: Responsible Behaviour in Cyberspace from 5-7 November 2018 in The Hague. The volume is edited by Dennis Broeders and Bibi van…

We strive to address the challenge of constructing a modeling language to write software which can take advantage of recent hardware developments (multicore, cloud) without compromising in its abstraction levels.

Which educational and child welfare interventions offer optimal opportunities for positive development to children with severe behavioral and emotional disorders.

This paper describes the development process of voting behavior in Chile; particularly the relationship between the class voting theory and the theory of cultural post-materialist vote is investigated.

The major aim is to develop, evaluate, and implement disease-generic cognitive-behavioral interventions through the internet in order to optimize tailored health care for patients with chronic somatic conditions.

The lipid matrix in the stratum corneum (SC), the upper layer of the skin, plays a critical role in the skin barrier. The matrix consists of ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs).

Although smartphones and other consumer cameras are increasingly used for scientific applications like citizen science, it’s still difficult to compare and combine data from different devices. PhD student Olivier Burggraaff developed a new easy-to-use standardised method which makes it possible for…

On July 5th, Mulugeta Tarekegne Tsegaye succesfully defended his doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Mulugeta on this great result.

Theoretical physicists research a special class of particles; Weyl fermions. They have found them to exhibit paradoxical behavior, in contradiction to a thirty-year old fundamental theory in electromagnetism. A possible application is a new kind of electronics—spintronics. Publication in Physical Review…
