Lien social et loisirs des seniors: un dĂ©fi pour lâanimation socioculturelle : une Ă©tude sur lâengagement des aĂźnĂ©es dans les activitĂ©s organisĂ©es Ă Fully
Actuellement, le vieillissement dĂ©mographique sâaccroĂźt et reprĂ©sente un dĂ©fi pour la sociĂ©tĂ©. Souvent, des reprĂ©sentations nĂ©gatives de la personne ĂągĂ©e en dĂ©coulent, comme le fait quâelles coĂ»tent cher et quâelles ne sont pas productives. LâavancĂ©e en Ăąge engendre le fait que la personne devra sâadapter aux diffĂ©rentes Ă©preuves du processus de vieillissement qui risque dâaltĂ©rer sa qualitĂ© de vie. Les politiques de la vieillesse mises en place ne prennent pas en compte la dimension sociale, câest-Ă -dire lâintĂ©gration des seniors dans la sociĂ©tĂ©. Les professionnelles de lâanimation socioculturelle pourraient rĂ©pondre aux besoins sociaux des seniors, car elles disposent dâoutils variĂ©s pour favoriser la participation de celles qui vivent encore Ă leur domicile. Mais pour quelles raisons les seniors sâengagent et participent dans les actions dâanimations socioculturelles ? Comment se perçoivent-elles ? Quelles activitĂ©s rĂ©alisent-elles ? Ont-elles des rĂ©seaux sociaux sur lesquels elles peuvent sâappuyer? Peuvent-elles facilement accĂ©der Ă leur environnement ? Ainsi, le but de cette recherche est de mettre en avant les facteurs influant lâengagement des seniors dans la vie en sociĂ©tĂ© et les activitĂ©s dâanimations socioculturelles. Pour mieux cerner la problĂ©matique du vieillissement, diffĂ©rents concepts thĂ©oriques seront abordĂ©s. Ils sont complĂ©tĂ©s par une dĂ©marche qualitative auprĂšs des aĂźnĂ©es, ce qui permet de valoriser leur vĂ©cu. Les rĂ©sultats ont dĂ©montrĂ© que, concernant lâĂ©chantillon choisi, les seniors se sentent bien. Elles sont donc ancrĂ©es dans la sociĂ©tĂ© et engagĂ©es dans les actions organisĂ©es Ă Fully. En conclusion, des pistes de bonnes pratiques seront explicitĂ©es, afin dâĂ©largir les points de vue sur cette thĂ©matique
Referential Choices in a Collaborative Storytelling Task: Discourse Stages and Referential Complexity Matter
During a narrative discourse, accessibility of the referents is rarely fixed once and for all. Rather, each referent varies in accessibility as the discourse unfolds, depending on the presence and prominence of the other referents. This leads the speaker to use various referential expressions to refer to the main protagonists of the story at different moments in the narrative. This study relies on a new, collaborative storytelling in sequence task designed to assess how speakers adjust their referential choices when they refer to different characters at specific discourse stages corresponding to the introduction, maintaining, or shift of the character in focus, in increasingly complex referential contexts. Referential complexity of the stories was manipulated through variations in the number of characters (1 vs. 2) and, for stories in which there were two characters, in their ambiguity in gender (different vs. same gender). Data were coded for the type of reference markers as well as the type of reference content (i.e., the extent of the information provided in the referential expression). Results showed that, beyond the expected effects of discourse stages on reference markers (more indefinite markers at the introduction stage, more pronouns at the maintaining stage, and more definite markers at the shift stage), the number of characters and their ambiguity in gender also modulated speakers' referential choices at specific discourse stages, For the maintaining stage, an effect of the number of characters was observed for the use of pronouns and of definite markers, with more pronouns when there was a single character, sometimes replaced by definite expressions when two characters were present in the story. For the shift stage, an effect of gender ambiguity was specifically noted for the reference content with more specific information provided in the referential expression when there was referential ambiguity. Reference content is an aspect of referential marking that is rarely addressed in a narrative context, yet it revealed a quite flexible referential behavior by the speakers
A Spectroscopically Confirmed Excess of 24 micron Sources in a Super Galaxy Group at z=0.37: Enhanced Dusty Star Formation Relative to the Cluster and Field Environment
To trace how dust-obscured star formation varies with environment, we compare
the fraction of 24 micron sources in a super galaxy group to the field and a
rich galaxy cluster at z~0.35. We draw on multi-wavelength observations that
combine Hubble, Chandra, and Spitzer imaging with extensive optical
spectroscopy (>1800 redshifts) to isolate galaxies in each environment and thus
ensure a uniform analysis. We focus on the four galaxy groups in supergroup
1120-12 that will merge to form a galaxy cluster comparable in mass to Coma. We
find that 1) the fraction of supergroup galaxies with SFR(IR)>3 Msun/yr is four
times higher than in the cluster (32% vs. 7%); 2) the supergroup's infrared
luminosity function confirms that it has a higher density of IR members
compared to the cluster and includes bright IR sources not found in galaxy
clusters at z<0.35; and 3) there is a strong trend of decreasing IR fraction
with increasing galaxy density, i.e. an IR-density relation, not observed in
the cluster. These dramatic differences are surprising because the early-type
fraction in the supergroup is already as high as in clusters, i.e. the
timescales for morphological transformation cannot be strongly coupled to when
the star formation is completely quenched. The supergroup has a significant
fraction (~17%) of luminous, low-mass, IR members that are outside the group
cores (R>0.5 Mpc); once their star formation is quenched, most will evolve into
faint red galaxies. Our analysis indicates that the supergroup's 24 micron
population also differs from that in the field: 1) despite the supergroup
having twice the fraction of E/S0s as the field, the fraction of IR galaxies is
comparable in both environments, and 2) the supergroup's IR luminosity function
has a higher L(IR)* than that previously measured for the field.Comment: Accepted by the Astrophysical Journa
Enabling planetary science across light-years. Ariel Definition Study Report
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. During its 4-year mission, Ariel will study what exoplanets are made of, how they formed and how they evolve, by surveying a diverse sample of about 1000 extrasolar planets, simultaneously in visible and infrared wavelengths. It is the first mission dedicated to measuring the chemical composition and thermal structures of hundreds of transiting exoplanets, enabling planetary science far beyond the boundaries of the Solar System. The payload consists of an off-axis Cassegrain telescope (primary mirror 1100 mm x 730 mm ellipse) and two separate instruments (FGS and AIRS) covering simultaneously 0.5-7.8 micron spectral range. The satellite is best placed into an L2 orbit to maximise the thermal stability and the field of regard. The payload module is passively cooled via a series of V-Groove radiators; the detectors for the AIRS are the only items that require active cooling via an active Ne JT cooler. The Ariel payload is developed by a consortium of more than 50 institutes from 16 ESA countries, which include the UK, France, Italy, Belgium, Poland, Spain, Austria, Denmark, Ireland, Portugal, Czech Republic, Hungary, the Netherlands, Sweden, Norway, Estonia, and a NASA contribution
Takeaways of Implementing a Native Rust UDP Tunneling Network Driver in the Linux Kernel
International audienceC is the primary programming language used in the Linux kernel. Recently, the Linux developer community oversaw the experimental addition of Rust into the kernel's build system. Networking is one of the areas often mentioned when discussing the adoption of Rust. In networking, both perfect memory management and performance are critical. In this paper, we present a Rust UDP tunneling driver for Linux, which provides UDP encapsulation between two peers. We use this driver to discuss design considerations of writing Rust networking code for Linux. We then compare the performance of our driver against a similar driver written in C. We find that our Rust driver performs slightly worse on a gigabit link for both latency (+0.1906%, p-value = 1.464eâ15) and throughput (â0.00090%, p-value = 6.004eâ5). We then discuss potential causes for that loss
Design and experimental evaluation of an infrared instrumentation for haptic interfaces
Conference of 2017 IEEE International Instrumentation and Measurement Technology Conference, I2MTC 2017 ; Conference Date: 22 May 2017 Through 25 May 2017; Conference Code:128947International audienceThis paper presents the design and experimental evaluation of the end-effector of a dexterous encounter type haptic interface aimed at allowing natural interactions with digital mockups in Virtual Reality. This end-effector has two purposes: first, it should be able to precisely measure the 6D position and orientation of a fingertip remotely without equipping the user with any marker on the skin or nail. Second, it should serve as contact surface when force feedback is required. Therefore, we make use of 9 proximity sensors, 8 of which are placed around the finger in two planes, the last one being in front of it. Our results show that, after calibration, this configuration effectively allows measuring the configuration of a mock-up representative of the finger with a good precision for various positions and orientations
Analysis of the directions in which forces are applied on the hand during manual manipulation and exploration
Conference of 10th IEEE World Haptics Conference, WHC 2015 ; Conference Date: 22 June 2015 Through 26 June 2015; Conference Code:116034International audienceHaptic interfaces aim at realistically simulating physical interactions within a Virtual Environment (VE) through the sense of touch. Therefore, they should display both a negligible impedance in free space and high forces and stiffness in contact. These constraints are however difficult to meet simultaneously. While compromises can usually be found when interacting through a handle grasped in hand, this is much more difficult when considering dexterous interactions with manual interfaces or exoskeletons due to the high number of degrees of freedom and limited space available. To ease their design, the authors previously made an analysis of the hand contact areas of interest for the simulation of the majority of interactions in a VE. It was shown that tracking and providing force feedback only on the five fingertips and the side of the index allows interacting naturally within a VE more than 50% of the time. This paper goes a step further and analyses in which directions these forces are applied on each hand area. A new result is that forces are required on the 6 areas of interest only normal to the skin, while tangential forces can be limited to 4 and even 1 area(s) depending on the direction

Health-related quality of life in young adults with congenital central hypoventilation syndrome due to PHOX2B mutations: a cross-sectional study
International audienceBackground: Congenital central hypoventilation syndrome (CCHS) is a rare genetic disease due to PHOX2B mutations. CCHS patients suffer from many autonomic disorders, dominated clinically by defective ventilatory automatisms. From birth, the life of CCHS patients depends on ventilatory support during sleep, involving a high burden of care. Whether or not this impairs the quality of life of these patients during adulthood remains unknown. Methods: We applied the medical outcome study short form-36 (SF-36) to 12 CCHS patients aged 15â33 (9 women) at the time of their passage from pediatric to adult care. Scores for the SF-36 dimensions were compared to the age-and gender-matched French reference population after transformation into standardized Z-scores. The SF-36 physical component summary score (PCS) and mental component summary score (MCS) were compared to American reference values. Results: Median Z-scores were significantly different from zero for PF (physical functioning, p = 0.020) and GH (general health perception, p = 0.0342) and for PCS (p = 0.020). The other physical dimensions (RP, role limitation due to physical function; BP, bodily pain) and the mental dimensions (VT, vitality; SF, social functioning; RE, role limitation due to emotional function; MH, mental health) and MCS were not altered. Conclusions: We conclude that, despite the physical constraints imposed by CCHS and its anxiogenic nature, this disease is associated with an impairment of health-related quality of life in young adults that remains moderate. Whatever the underlying explanations, these results convey hope to parents with a child diagnosed with CCHS and for patients themselves
