Other-regarding behaviour: Testing guilt- and reciprocity-based models

We analyse two types of belief-dependant models of social preferences: guilt aversion and reciprocity. In particular, we test the relevance of their input variables (second-order beliefs and general dispositions for guilt/reciprocity). The data confirm the predictions of belief-dependant models. Both second-order beliefs and a participant's sensitivity to guilt/reciprocity are relevant for the decisions taken. Second-order beliefs appear to have an inverse U-shaped effect on the extent of kind behaviour.social preferences, other-regarding behaviour, belief-dependent models, experiments, trust game, guilt aversion, beliefs, psychological game theory, emotions, reciprocity

Marangoni flow in freely suspended liquid films

We demonstrate controlled material transport driven by temperature gradients in thin freely suspended smectic films. The films with submicrometer thicknesses and lateral extensions of several millimeters were studied in microgravity during suborbital rocket flights. In-plane temperature gradients cause two specific Marangoni effects, directed flow and convection patterns. At low gradients, practically thresholdless, flow transports material with a normal (negative) temperature coefficient of the surface tension, $d\sigma/dT<0$, from the hot to the cold film edge. That material accumulates at the cold film border. In materials with positive temperature coefficient, $d\sigma/dT>0$, the reverse transport from the cold to the hot edge is observed. We present a model that describes the effect quantitatively.Comment: 5 pages, 5 figure
