Les parcours d'insertion des jeunes

2011

Cet article présente une méthode pour élaborer des typologies d'itinéraires individuels qui prenne en compte la dynamique longitudinale des parcours. Elle s'applique lorsque ces itinéraires sont décrits à partir de calendriers. L'originalité de cette méthode réside à la fois dans le mode de calcul de la distance entre trajectoires, et dans la procédure de classification basée sur les cartes d'auto-organisation de Kohonen. La propriété principale de la distance est de prendre en compte de la proximité entre les états et son évolution dans le temps. Cette méthode est appliquée ici à l'analyse des trajectoires professionnelles, à partir de données du Céreq permettant le suivi mensuel sur sept …

Les compétences sociales et non académiques dans les parcours scolaires et professionnels

2016

National audience; L'approche par « compétences » fait l'objet de nombreux débats dans le système éducatif français. C'est sans doute la préoccupation centrale des politiques actuelles d'éducation et de formation. Si les compétences académiques et professionnelles commencent à être bien référencées, de nombreuses questions se posent en termes de compétences sociales et non académiques qui semblent pourtant déterminantes dans la réussite scolaire et professionnelle. Comment les mesure-t-on ? L'école peut-elle et doit-elle les enseigner ? Peuvent-elles faciliter l'apprentissage d'autres compétences ? Comment influencent-elles les trajectoires professionnelles des jeunes à la sortie du système…

Long-term disability trajectories in relapsing multiple sclerosis patients treated with early intensive or escalation treatment strategies

2021

Background and aims: No consensus exists on how aggressively to treat relapsing–remitting multiple sclerosis (RRMS) nor on the timing of the treatment. The objective of this study was to evaluate disability trajectories in RRMS patients treated with an early intensive treatment (EIT) or with a moderate-efficacy treatment followed by escalation to higher-efficacy disease modifying therapy (ESC). Methods: RRMS patients with ⩾5-year follow-up and ⩾3 visits after disease modifying therapy (DMT) start were selected from the Italian MS Registry. EIT group included patients who received as first DMT fingolimod, natalizumab, mitoxantrone, alemtuzumab, ocrelizumab, cladribine. ESC group patients rec…

Maternal body mass index, change in weight status from childhood to late adulthood and physical activity in older age

2021

This study aimed to examine the longitudinal associations of maternal body mass index (BMI), weight status in childhood and late adulthood and device-measured total physical activity (TPA) in older age. The study involves 552 participants from Helsinki Birth Cohort Study who were born in Helsinki, Finland, in 1934-1944. TPA was measured with a multisensory body monitor at a mean age of 70 years and expressed in metabolic equivalent of task hours/day (METh/d). Childhood overweight (BMI > 85th percentile) was based on school health records at 6-7 years of age, and late adulthood overweight (BMI >= 25 kg/m(2)) was based on clinical measurements at the mean age of 61 years. Childhood overweight…

Studies on the response of a water-Cherenkov detector of the Pierre Auger Observatory to atmospheric muons using an RPC hodoscope

2020

Extensive air showers, originating from ultra-high energy cosmic rays, have been successfully measured through the use of arrays of water-Cherenkov detectors (WCDs). Sophisticated analyses exploiting WCD data have made it possible to demonstrate that shower simulations, based on different hadronic-interaction models, cannot reproduce the observed number of muons at the ground. The accurate knowledge of the WCD response to muons is paramount in establishing the exact level of this discrepancy. In this work, we report on a study of the response of a WCD of the Pierre Auger Observatory to atmospheric muons performed with a hodoscope made of resistive plate chambers (RPCs), enabling us to selec…

An empirically grounded agent based simulator for the air traffic management in the SESAR scenario

2017

In this paper we present a simulator allowing to perform policy experiments relative to the air traffic management. Different SESAR solutions can be implemented in the model to see the reaction of the different stakeholders as well as other relevant metrics (delay, safety, etc). The model describes both the strategic phase associated to the planning of the flight trajectories and the tactical modifications occurring in the en-route phase. An implementation of the model is available as an open-source software and is freely accessible by any user. More specifically, different procedures related to business trajectories and free-routing are tested and we illustrate the capabilities of the mode…

A synoptic view of solar transient evolution in the inner heliosphere using the Heliospheric Imagers on STEREO

2009

[1] By exploiting data from the STEREO/heliospheric imagers (HI) we extend a well-established technique developed for coronal analysis by producing time-elongation plots that reveal the nature of solar transient activity over a far more extensive region of the heliosphere than previously possible from coronagraph images. Despite the simplicity of these plots, their power in demonstrating how the plethora of ascending coronal features observed near the Sun evolve as they move antisunward is obvious. The time-elongation profile of a transient tracked by HI can, moreover, be used to establish its angle out of the plane-of-the-sky; an illustration of such analysis reveals coronal mass ejection …
