La montée de la préoccupation scolaire des familles populaires
The Swiss secondary education system was reformed in the 1960s. This change, which is still ongoing today, is almost complete. In 1969 education for working-class pupils was extended from 13 to 15, although at a basic level, today a large majority of ...

Studying the Same-Gender Preference as a Defining Feature of Cultural Contexts
Research on culture would be enriched by studying the connection between gender and peer relations. Cultures vary in the roles, privileges, opportunities, and right that are ascribed to girls and boys. They are known to also differ in the degree to which

This paper explores, using an Agent-based model approach (ABM), the conditions for the emergence and the structuration of quality wine’s historical areas as described in the work of Roger Dion, particularly in his article entitled “Querelles des anciens ...

Conformally covariant parameterizations for relativistic initial data
We revisit the Lichnerowicz-York method, and an alternative method of York, in order to obtain some conformally covariant systems.

Non-singular, vacuum, stationary space-times with a negative cosmological constant
We construct infinite dimensional families of non-singular stationary space times, solutions of the vacuum Einstein equations with a negative cosmological constant.Comment: minor corrections, an inessential uniqueness claim ...

We use an elliptic system of equations with complex coefficients for a set of complex-valued tensor fields as a tool to construct infinite-dimensional families of non-singular stationary black holes, real-valued Lorentzian solutions of the Einstein ...

Birth data from developed countries indicates that the average paternal age is increasing. As the trend to older fatherhood has become established, concerns have been raised that this may be linked to adverse outcomes, such as pregnancy complications, congenital anomalies, and long-term health implications for the child.

Generalising the results in arXiv:1612.00281, we construct infinite-dimensional families of non-singular stationary space times, solutions of Yang-Mills-Higgs-Einstein-Maxwell-Chern-Simons-dilaton-scalar field equations with a negative cosmological ...
