Abstract

Stigma surrounding mental health, particularly among men, remains a significant barrier to men engaging with support services for their mental health. Despite increasing evidence of interventions targeting different aspects of stigma reduction, there is a notable gap in the literature concerning male-specific mental health stigma reduction interventions and on the underlying behavior change techniques (BCTs) used to reduce stigma. The purpose of this review is to synthesize the evidence relating to the impact of mental health stigma reduction interventions among men and to explore the underlying BCTs associated with each intervention. The review was restricted to empirical research reporting on interventions targeting mental health stigma in male-dominated populations. The quality appraisal was conducted using the Mixed Methods Analysis Tool and a narrative synthesis was conducted. Fourteen articles reporting on 11 interventions were included for review, while 20 outcome measures were used. Perceived public stigma attracted the largest number of interventions with a lesser focus on self or personal stigma. Nineteen BCTs were identified across the interventions with information about health consequences and self-monitoring of behavior being the most common followed by credible source, social contact, and behavior practice/rehearsal. This is discussed in relation to the wider literature. The methodological issues highlighted in the articles limit the conclusions and recommendations that can be drawn from the review. Recommendations for further research include standardizing the scales used in stigma measurement, in-depth reporting of intervention descriptions, and greater use of theory to guide intervention development.

Abstract

Mental ill-health and suicide represent a significant proportion of the burden of global disease among men. Connell's relational theory of masculinities provides a useful framework to explore how mental health literacy, mental health stigma, and delayed help-seeking and help-offering behaviors are associated with mental ill-health among men, particularly within male-dominated industries. To address the high incidences of mental ill-health in male-dominated industries, several workplace interventions targeting these outcomes have been implemented. No review to date has examined the current state of evidence for these interventions or identified the behavior change techniques used. This review was restricted to empirical, quantitative research reporting on psychosocial interventions targeting mental health literacy, stigma, and help-seeking and help-offering behaviors in male-dominated industries. Quality appraisal was completed using the Effective Public Health Practice Project and a narrative synthesis was conducted. Twelve articles were included for review which reported on four distinct interventions. The methodological quality of two articles was strong, three moderate and seven weak. The strongest evidence of intervention effects related to mental health literacy and help-seeking intentions. There was less evidence relating to help-offering and help-seeking behaviors and mental health stigma. Sixteen behavior change techniques were identified across interventions that are discussed in relation to the wider men's health literature. The evidence on psychosocial interventions in male-dominated industries is limited due to methodological and conceptual issues. Recommendations for future research include standardized reporting of intervention descriptions, the use of theory to guide intervention development, and utilizing validated and reliable outcome measures.

Abstract

Based on a contents and discourse analysis of November 13 and 14, 2015 TV “breaking news” programs, this article analyzes how the heterogeneity of TV discourse about the terror event shapes distinct narrative schemes. Since live stories and comments partly rest on prediscursive processes, they include traces of past and future narratives, thus showing to what extent the French society can conditionally be conceived as a “post-attack” society., À partir d’une analyse de contenu et de discours des éditions télévisées spéciales des 13 et 14 novembre 2015, cet article analyse comment l’hétérogénéité des mises en récit de l’événement terroriste façonne des cadres interprétatifs distincts. Intégrant en partie des phénomènes prédiscursifs, les discours énoncés en direct contiennent les sédiments de récits antérieurs et à venir. L’étude de cet ensemble discursif invite à s’interroger sur la définition d’une société « post-attentats ».

Abstract

International audience; Qu'est-ce que l'éducation aux médias ? Originellement, elle s'est définie par la nécessité de développer dès le plus jeune âge un esprit critique face aux contenus médiatiques. À l'heure du numérique, elle doit aussi développer la créativité des jeunes et leur autonomie pour qu'ils puissent produire des énoncés médiatiques de plus en plus originaux et adaptés à leurs besoins. Ils ne sont pas seuls pour accomplir ce chemin, l'École peut et doit les accompagner. Les pédagogies innovantes apparaissent comme un levier prometteur pour les enseignants, réconciliant éducation par les médias et éducation aux médias. Il s'agit désormais d'un défi mondial, mais auquel les réponses politiques et les usages médiatiques apportés sont fortement contrastés. Cet ouvrage propose une perspective internationale d'expériences et de travaux de recherche qui montre, par la diversité des contributions, la richesse de cette question.

Abstract

National audience; Obtaining the effective properties of a composite material needs the use or more or less sophisticated models. If a full field method allows validating, even calibrating, mean field approaches, such a calibration can be pertinent only if the full field model is representative of the material behavior. The work presented in this article concerns the compromise to find between the considered microstructure size and its representability. First, a statistically representative cells element (SRCE) of a unidirectional short-fiber composite is defined. In order to do this, the geometrical and morphological parameters, and the mechanical properties of over 180 different cells are compared and analyzed. In the form of an experimental plan, the geometrical and morphological data feed a 3D modeler which supports a mesh that is adapted to the microstructure. © Lavoisier 2016.

Abstract

Control and computation co-design deals with the interaction between feedback control laws design and their implementation on a real execution resource. Control design is often carried out in the framework of continuous time, or under the assumption of ideal sampling with equidistant intervals and known delays. Implementation on a real-time execution platform introduces many timing uncertainties and distortions to the ideal timing scheme, e.g. due to variable computation durations, complex preemption patterns between concurrent activities, uncertain network induced communication delays or occasional data loss. Analyzing, prototyping, simulating and guaranteeing the safety of complex control systems are very challenging topics. Models are needed for the mechatronic continuous system, for the discrete controllers and diagnosers, and for network behavior. Real-time properties (task response times) and the network Quality of Service (QoS) influence the controlled system properties (Quality of Control, QoC). To reach effective and safe systems it is not enough to provide theoretic control laws and leave programmers and real-time systems engineers just do their best to implement the controllers. This report first describes, through the detailed design of a quadrotor drone controller, the main features of {\sc Orccad}, an integrated development environment aimed to bridge the gap between advanced control design and real-time implementation. Besides control design and implementation, a real-time (hardware-in-the-loop) simulation has been designed to assess the control design with a simulated target rather than with the real plant. Using this HIL structure, several experiments using flexible real-time control features are reported, namely Kalman filters subject to data loss, control under (m,k)-firm constraints, control with varying sampling rates and feedback scheduling using the MPC approach.

Abstract

Discrete time controller using variable sampling can ba interesting in several cases, for axample when the measure, even if send periodically, is received with a variable interval. This is the case in submarine environement, when the altitude measurement is done using an ultrasonic sensor. Discrete control laws synthesis with variable sampling period have already been studied for LTI systems. The results are here extended to Linear Parameter Varying systems, that allow to keep some non-linearities as parameters of a linear system. In particular, two approaches are investigated : the polytopic and the LFR. The proposed method is applied for the altitude control of an autonomous underwater vehicle (AUV). Simulations results will show the interest of the method, in particular how results are improved by adding some parameters coming from the non linear model., L'utilisation de correcteur discret à période d'échantillonnage variable peut être intéressante dans plusieurs cas, par exemple lorsque la mesure, bien qu'envoyée de façon périodique, est reçue à intervalle variable. C'est le cas en milieu marin lorsque la mesure d'altitude est effectuée avec un capteur à ultrason (la durée du trajet du signal dans l'eau dépend de la distance par rapport au fond). Le délai variable entre deux réceptions de mesures, peut être vu comme une variation de période d'échantillonnage pour le contrôleur. La synthèse de lois de commande discrète à période d'échantillonnage variable a déjà été étudiée pour des systèmes stationnaires. On se propose ici d'étendre cette méthode pour des systèmes Linéaires à Paramètres Variants (LPV), qui permettent de conserver des paramètres importants d'un système non-linéaire en temps que paramètres d'un système linéaires. La synthèse de contrôleur repose sur le méthodologie H∞, appliquée aux systèmes LPV. En particulier, on s'intéressera à deux approches existantes dans la littérature : l'approche polytopique (où le paramètre variant évolue dans un volume convexe) et la Représentation Linéaire Fractionnelle (LFR). La méthode proposée est appliquée au contrôle d'un AUV (Autonomous Underwater Vehicle), qui est système difficile à contrôler du fait d'importantes non-linéarités. Des résultats de simulations permettront de montrer l'intérêt de la méthode pour le contrôle d'altitude d'un AUV, et notamment les améliorations apportées par l'ajout de paramètres issus du système non-linéaire au modèle utilisé pour la synthèse des régulateurs.

Abstract

International audience; This paper deals with the robust control of an Autonomous Underwater Vehicle (AUV) subject to communication constraints. The aim is the design of a gain-scheduled varying sampling controller using non periodic measurements from ultrasonic sensors. The contribution of this work lies in a new model formulation of varying sampling discrete-time systems using the Linear Fractional Transformation (LFT) representation. This allows to design, in the LFT context, an Hinf controller whose matrices are scheduled w.r.t the varying control interval. Moreover the proposed design ensures a performance adaptation when the sampling interval varies. This methodology is developed for AUV and emphasizes important improvements compared with an Hinf discrete-time control with fixed sampling.

Abstract

A consequence of the execution of control algorithms on digital distributed platforms is inducing delays, jitter and various limitations in sampling rate from different sources in the control loops. These disturbances should be taken into account in the control algorithms design and tuning. Control systems are often cited as examples of "hard real-time systems" where jitter and deadline violations are strictly forbidden. In fact experiments show that this assumption may be false for closed-loop control. Any practical feedback system is designed to obtain some stability margin and robustness w.r.t. the plant parameters uncertainty. This also provides robustness w.r.t. timing uncertainties: closed-loop systems are able to tolerate some amount of sampling period and computing delays deviations, jitter and occasional data loss without loss of stability or integrity. Hence the design of dependable distributed control systems may rely on robust controllers, i.e. controllers which are slightly sensitive to both process model and execution resource uncertainties, or on controllers which are made adaptive w.r.t. the variations of the control intervals and other implementation induced disturbances. Section 2 provides new results concerning the control of systems with delays. A novel analysis of linear systems under asynchronous sampling is provided. This approach is based on the discrete-time Lyapunov Theorem applied to the continuous-time model of the sampled-data systems. Tractable conditions are derived to ensure asymptotic stability and also to obtain an estimate of the exponential rate of the solutions. Examples show the efficiency of the method and the reduction of the conservatism compared to other results from the literature. Moreover the methodology addresses the stability analysis of systems under several sampling periods. We show that a sampled-data system can be stable even if one of the sampling period leads to instability. This has been treated by a continuous-time approach and allows considering uncertain or time-varying systems. An extension of the method includes transmission delays in the control loop. As the variations of the control intervals can be both a consequence of network induced delays and a control variable to manage the CPU and/or network load, robust variable sampling control design is investigated in section 3. Here it is assumed that the control interval is itself a control parameter, e.g. which can be adapted at run-time by a feedback scheduler to cope with operating conditions in a varying environment. The control design is stated using the formulation of Linear Parameters Varying (LPV) systems, where the sampling interval is considered as a varying and measurable parameters of the system. Previous results using a polytopic model of a discretized plant are recalled. A new design using a Linear Fractional Transform (LFT) is developed, where the control interval is considered as a system's uncertainty. This new approach is expected to be more tractable that the polytopic one when the system has several varying parameters. Both designs are assessed and compared using as testbed the control of Autonomous Underwater Vehicles using scheduled ultrasonic sensors for control and navigation. 2

30. Modélisation et définition d'une cellule élémentaire statistiquement représentative. Application à un composite renforcé en fibres courtes unidirectionnelles.

Abstract

Obtaining the effective properties of a composite material needs the use or more or less sophisticated models. If a full field method allows validating, even calibrating, mean field approaches, such a calibration can be pertinent only if the full field model is representative of the material behavior. The work presented in this article concerns the compromise to find between the considered microstructure size and its representability. First, a statistically representative cells element (SRCE) of a unidirectional short-fiber composite is defined. In order to do this, the geometrical and morphological parameters, and the mechanical properties of over 180 different cells are compared and analyzed. In the form of an 232 RCMA. Volume 26 - n° 2/2016 experimental plan, the geometrical and morphological data feed a 3D modeler which supports a mesh that is adapted to the microstructure. [ABSTRACT FROM AUTHOR]

Abstract

Biochemical methods were selected to evaluate the role of exopolymeric substances in the stability of biofilms used in bioremediation processes. Biofilms of Thiomonas arsenivorans formed on pozzolana were thus treated with pronase (protein target), lectins (Con A or PNA), calcofluor or periodic acid (polysaccharides target), DNase (DNA target), and lipase (triglycerides target). Neither protease nor DNase treatments had any effect on bacterial adhesion. Lectins and calcofluor treatments mainly affected young biofilms. Lipase treatment had a noticeable effect on biofilm stability whatever the biofilm age. Results suggest that it would be an increased resistance of mature biofilms that protects them from external attacks.
