Betrayal Aversion on Four Continents

Due to betrayal aversion, people take risks less willingly when the agent of uncertainty is another person rather than nature. Individuals in four countries (Brazil, Switzerland, the United Arab Emirates and the United States) confronted either a binary-choice trust game or a risky decision offering the same payoffs and probabilities. Risk acceptance was calibrated by asking individuals their “...

The deep structure of continents

The Lehmann discontinuity at 220-km depth is an important global feature which occurs under both oceans and continents. It is a barrier to penetration by young lithosphere and marks the base of seismicity in regions of continent-continent collision. The strong lateral variation in upper mantle velocities occurs mainly above this depth. Continental roots extend no deeper than about 150-200 km. T...

Knot spinning

This exposition is intended to provide some introduction to higher-dimensional knots embeddings of Sn−2 in S through spinning constructions. Once our shoe laces, those archetypical hand tools of knot theory, have been turned into spheres, how can we construct and visualize concrete examples of such knots? There are many important ways to construct higher-dimensional knots. If we are interested ...
