The level of congruence between parties and their voters can vary greatly from one policy issue to another, which raises questions regarding the effectiveness of political representation. We seek to explain variation in party–voter congruence across issues and parties.

In this article, Amandine Lerusse, investigates how the order of performance information affects local politicians’ issue prioritisation decisions.

The lipids in the uppermost layer of the skin, the stratum corneum (SC), play an important role in the skin barrier function. The three main SC lipid classes are ceramides (CER), cholesterol and free fatty acids.

This thesis has shed light on some of the ways in which the local electrolyte composition can differ from the bulk and how these changes in the local reaction environment can determine the activity and/or selectivity of two important electrocatalytic reactions, namely, electrochemical CO2 reduction…

This research focuses on the (Quantum) Dynamics (QD) of the reactive scattering of H2 from metal surfaces.

In this conversation-analytic study, the authors analyze conversations between researchers from different disciplines and community members to examine relationship building in real life. This is an open access article under the Creative Commons By license.

The outermost layer of the skin, the stratum corneum (SC), is responsible for the skin barrier function, protecting the body from pathogens, chemicals and other unwanted substances from the external environment. The SC lipid matrix provides the only continuous pathway through the SC and is considered…

Together with Pepijn Tuinier and Thijs Brocades Zaalberg, Sebastiaan Rietjens researched the role of trust in an international intelligence cooperation.

This dissertation reports on the beliefs and perceptions of Chinese and Dutch university teachers regarding the role of research in university teaching and how these beliefs and perceptions can be explained by their cultural, institutional and individual background characteristics

The skin barrier function is provided by the stratum corneum (SC). The lipids in the SC are composed of three lipid classes: ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs) which form two crystalline lamellar structures. In the present study, we investigate the effect of CER chain length…
