Interactive Effect of Dispositional Cognitive Avoidance, Magnitude of Threat, and Response Efficacy on the Persuasive Impact of Threat Communications

2012

This internet study investigated the effect of individual differences in cognitive avoidance on the persuasive impact of threat communications. A total of 289 participants completed a measure of dispositional cognitive avoidance and read either a high- or a low-threat communication that provided either an effective response to reduce the threat or not. We found that cognitive avoidance did not moderate the effect of magnitude of threat when response efficacy was low. By contrast, cognitive avoidance was relevant when efficacy was high: After a high-threat message, low cognitive avoiders reported more favorable attitudes toward and intentions to adopt the action recommendation than high cog…

Repairing the living: ethics of ecological compensation

2017

The mechanism of ecological compensation has a paradox, it is denounced on the ethical level and consecrated on the legal level. While they are supposed to repair the environmental damages, the compensatory measures are accused of bad intentions: authorization to destroy biodiversity, financial drift of the management of nature... Despite these criticisms, ecological compensation can find a a profound moral issue if it is used like an accountability tool between human and nature, and more broadly, an instrument for dynamic management of territories.

A Novel Architecture for Inter-FPGA Traffic Collision Management

2014

International audience; —with the increasing complexity of various communi-cations and applications, Network-On-Chip (NoC) is one of the most efficient communication structures. Multi-FPGA platforms are considered as the most appropriate experimental solutions to emulate a large size of MPSoCs (Multi-Processor System-on-Chip) based on a NoC. The deployment of the NoC into several FPGAs requires the use of inter-FPGA communication links. The number and performance of external links restrict the bandwidth of communication. Currently, the number of inter-FPGA signals is considered as a substantial problem in NoC implemented on Multi-FPGA architectures. In this paper, we propose the integration…

Maternal effects in vulnerability to eye-parasites and correlations between behavior and parasitism in juvenile Arctic charr

2017

Hatchery-reared fish show high mortalities after release to the wild environment. Explanations for this include potentially predetermined genetics, behavioral, and physiological acclimation to fish farm environments, and increased vulnerability to predation and parasitism in the wild. We studied vulnerability to Diplostomum spp. parasites (load of eye flukes in the lenses), immune defense (relative spleen size) and antipredator behaviors (approaches toward predator odor, freezing, and swimming activity) in hatchery-reared juvenile Arctic charr (Salvelinus alpinus) using a nested mating design. Fish were exposed to eye-fluke larvae via the incoming water at the hatchery. Fish size was positi…

Temporal Series Analysis on Avoidable Mortality for the Assessment of an Intervention Program in a Hospital

2017

Background: Avoidable mortality (AM) is one of the most important health indicators (HI) and represents the quality of care in a hospital.Objective: This study measured the efficacy of a training program for a hospital healthcare staff to reduce AM.Methods: This epidemiological study on community intervention analyzed time-series data on HI by semesters from 2008 to 2015. The pre-intervention phase was examined from January 2008 to December 2014; the intervention phase was investigated in the first semester of 2015; and the post-intervention phase was examined in the second semester of 2015.Results: Resindicate a series with a rising tendency until the 14th semester and a pronounced descent…

Data-based modeling of vehicle collision by LPV-ARMAX model approach

2013

Vehicle crash are considered to be events with high complexity from the mathematical points of view. The high experiment cost and huge time-consumption make the establishment of a mathematical model of vehicle crash which can simplify the analysis process in great demand. In this work, we present the application of LPV-ARMAX model to simulate the car-to-pole collision with different initial impact velocities. The parameters of the LPV-ARMAX are assumed to be functions of the initial impact velocities. Instead of establishing a set of LTI models for vehicle crashes with various impact velocities, the LPV-ARMAX model is comparatively simple and applicable to predict the responses of new colli…

1D Compression Behaviour of Opalinus Clay

2017

One of the main concerns related to tunnel excavations, drilling operations and wellbore stability in shales is the generation of excess pore water pressure due to changes in mechanical stress; therefore the consolidation of shales is a fundamental process that must be considered. This paper presents a compre- hensive methodology for analysing the compression and consolidation behaviour of shales. An apparatus to perform high-pressure oedometric tests is presented and an analytical method is introduced to analyse the shale consolidation behaviour, which allows information to be gathered on the coeffi cient of consolidation, stiffness, poroelastic properties, and permeability of the tested m…

On PD mechanisms at high temperature in voids included in an epoxy resin

2001

In this paper the effects of temperature on partial discharge (PD) activity taking place inside a spherical void in epoxy resin system are studied. Indeed, some experimental tests previously performed on specimens, having different void shapes, under multi-stress condition of temperature and voltage, have shown very different PD amplitude distributions at temperatures higher than ambient. However, this phenomenon cannot be explained only by taking into account the different thermobaric conditions of the enclosed gas. In consequence of the general physical inaccessibility of such voids, a study is here performed using a numerical model based on an evolutionary optimization algorithm. This is…

An Intelligent Car Driver for safe Navigation with Fuzzy Obstacle Avoidance.

2009

In order to respond effectively to the environment uncertainties, autonomous vehicles are generally equipped with sensors. The proposed car guidance system is equipped with an intelligent controller, based on fuzzy logic, which calculates the speed and wheels orientation in order to follow a path while it is avoiding unknown obstacles. Better fluidity of driving are obtained using future-path, car dimension and car position prevision. Vehicle symmetries also speed-up and simplify the guidance system reducing the inputs and the rules numbers.
