Hommage à Laure Beaumont-Maillet (1947-2016)

Hommage to reactive psychosis.

When looking back in the history of psychiatry, the concept of reactivity had very variable impact on ethiological considerations. If classification of mental disorders is taken as a proxy, it seems that this impact is presently at the lowest that it has been in the last hundred years. The author gives a short historical overview of concept of reactive psychosis, followed by a description of th...

Christophe Boucher Bertrand Maillet

Since at least Engle (1982) and Stock and Watson (2002), we know that the conditional variance of future output and inflation evolves over time. However, in these seminal contributions, the risk of real activity and inflation is implicitly considered as symmetric. In this paper, we investigate the time evolution of the conditional distribution of macroeconomics variables with a special interest...

Mathematical Study of Rotating Fluids with Resonant Surface Stress Anne-laure Dalibard and Laure Saint-raymond

We are interested here in describing the linear response of a highly rotating fluid to some surface stress tensor, which admits fast time oscillations and may be resonant with the Coriolis force. In addition to the usual Ekman layer, we exhibit another much larger boundary layer, and we prove that for large times, the effect of the surface stress may no longer be localized in the vicinity of th...

Lizards, ticks and contributions to Australian parasitology: C. Michael Bull (1947–2016)

Professor C. Michael Bull was a great scientist and mentor, and an Associate Editor of this journal. While his research career spanned the fields of behavioural ecology, conservation biology and herpetology, in this article, we pay tribute to his major contribution to Australian parasitology. Mike authored more than eighty articles on host-parasite ecology, and revealed major insights into the ...
