The Influence of Negative Newspaper Coverage on Consumer Confidence: The Dutch Case

This paper studies the empirical relationship between the real economy, consumer confidence and economic news coverage in national newspapers for the Netherlands during the period 1990-2008. Media-attention for economic developments Granger-causes consumer confidence, with more negative news decreasing consumer confidence; this result holds when controlling for the real economy (stock-market). This suggests that in line with many popular concerns negative news is among factors influencing the hardness of the landing of the current credit-crisis, whereas positive news might have been a contributing factor in the build-up of asset- and housing bubbles.Consumer Confidence;Media;VAR-analysis.

Fluctuating shells under pressure

Thermal fluctuations strongly modify the large length-scale elastic behavior of crosslinked membranes, giving rise to scale-dependent elastic moduli. While thermal effects in flat membranes are well understood, many natural and artificial microstructures are modeled as thin elastic {\it shells}. Shells are distinguished from flat membranes by their nonzero curvature, which provides a size-dependent coupling between the in-plane stretching modes and the out-of-plane undulations. In addition, a shell can support a pressure difference between its interior and exterior. Little is known about the effect of thermal fluctuations on the elastic properties of shells. Here, we study the statistical mechanics of shape fluctuations in a pressurized spherical shell using perturbation theory and Monte Carlo computer simulations, explicitly including the effects of curvature and an inward pressure. We predict novel properties of fluctuating thin shells under point indentations and pressure-induced deformations. The contribution due to thermal fluctuations increases with increasing ratio of shell radius to thickness, and dominates the response when the product of this ratio and the thermal energy becomes large compared to the bending rigidity of the shell. Thermal effects are enhanced when a large uniform inward pressure acts on the shell, and diverge as this pressure approaches the classical buckling transition of the shell. Our results are relevant for the elasticity and osmotic collapse of microcapsules.Comment: To appear in PNAS; accepted version including Supplementary Informatio

News consumption and its unpleasant side effect:Studying the effect of hard and soft news exposure on mental well-being over time

Following the news is generally understood to be crucial for democracy as it allows citizens to politically participate in an informed manner; yet, one may wonder about the unintended side effects it has for the mental well-being of citizens. With news focusing on the negative and worrisome events in the world, framing that evokes a sense of powerlessness, and lack of entertainment value, this study hypothesizes that news consumption decreases mental well-being via negative hedonic experiences; thereby, we differentiate between hard and soft news. Using a panel survey in combination with latent growth curve modeling (n = 2,767), we demonstrate that the consumption of hard news television programs has a negative effect on the development of mental well-being over time. Soft news consumption, by contrast, has a marginally positive impact on the trend in well-being. This can be explained by the differential topic focus, framing and style of soft news vis-à-vis hard news. Investigating the effects of news consumption on mental well-being provides insight into the impact news exposure has on variables other than the political ones, which definitively are not less societally relevant
