Where do immigrants retire to?

As migration rates increase across the world, the choice of whether to retire in the host or home country is becoming a key decision for up to 15% of the world’s population, and this proportion is growing rapidly. Large waves of immigrants who re-settled in the second half of the 20th century are now beginning to retire. Although immigrants’ location choice at retirement is an area that has barely been studied, this decision has crucial implications for health care and social protection expenditures, both in host and origin countries

"All children are dwarfs": medical discourse and iconography of children's bodies

Ancient medical discourse conveys a mainly negative view of children's bodies. From Hippocrates to Galen, newborn children are defined as imperfect and ugly beings, associating an excessive softness and weakness with various anomalies. Aristotle links their physical disproportions with those of dwarfs and animals. These disproportions induce physiological troubles and mental incapacities. Hot-tempered and moist, children are dominated by their emotions and sensations. Often authors group them with other beings regarded as inferior, such as women, the old, the sick, the insane, the drunk. How are mythical and human children rendered in iconography? Do their characteristics correspond to the medical discourse? The image of children's bodies changes with the passing of time; the miniature adult of archaic Greece gradually turns into the plump toddler of the Hellenistic period. How can we interpret these transformations? Does the evolution of iconography reflect the transformation of society or does it mirror the progress of medical knowledge

Principaux facteurs qui influencent la qualité sanitaire du lait à la Réunion

Optical emission from TiO2 plasma, generated by a nanosecond laser is spectroscopically analysed. The main chemical species are identified and the spatio-temporal distribution of the plasma parameters such as electron temperature and density are characterized based on the study of spectral distribution of the line intensities and their broadening characteristics. The parameters of laser induced plasma vary quickly owing to its expansion at low background pressure and the possible deviations from local thermodynamic equilibrium conditions are tested to show its validity

Automatic lip tracking: Bayesian segmentation and active contours in a cooperative scheme

International audienceAn algorithm for speaker's lip contour extraction is pre- sented in this paper. A color video sequence of speaker's face is acquired, under natural lighting conditions and without any particular make-up. First, a logarithmic color transform is performed from RGB to HI (hue, intensity) color space. A bayesian approach segments the mouth area using Markov random field modelling. Motion is combined with red hue lip information into a spatiotemporal neighbourhood. Simultaneously, a Region Of Interest and relevant boundaries points are automatically extracted. Next, an active contour using spatially varying coefficients is initialised with the results of the preprocessing stage. Finally, an accurate lip shape with inner and outer borders is obtained with good quality results in this challenging situation
