Management of active ageing in France in businesses: Some case-studies

If some European countries started work on age management long ago, several reports confirmed the urgency and the complexity of age management in France. The low participation of French older workers in the labour market was the result of premature exclusion, within a context of high unemployment and industrial restructuring. Discrimination concerning access to jobs and training persists with regard to older workers. The management of ages is not yet something from which enterprises could expect a return, because of the socio-cultural negative perceptions and image of older workers. Nevertheless, some companies start to implement innovative initiatives and test new solutions for promoting active ageing. This article brings some examples of those experiences and concludes with the necessity to reconciliate “age, work and training” to favour social links and better sharing between generations promoting “aging, living and working well together”.older workers, work, human resource management, inter-generational links

Wavefront sensing with a brightest pixel selection algorithm

Astronomical adaptive optics systems with open-loop deformable mirror control have recently come on-line. In these systems, the deformable mirror surface is not included in the wavefront sensor paths, and so changes made to the deformable mirror are not fed back to the wavefront sensors. This gives rise to all sorts of linearity and control issues mainly centred on one question: Has the mirror taken the shape requested? Non-linearities in wavefront measurement and in the deformable mirror shape can lead to significant deviations in mirror shape from the requested shape. Here, wavefront sensor measurements made using a brightest pixel selection method are discussed along with the implications that this has for open-loop AO systems. Discussion includes elongated laser guide star spots and also computational efficiency.Comment: 10 pages, 12 figures, accepted by MNRA
