Source unreliability decreases but does not cancel the impact of social information on metacognitive evaluations

2015

International audience; Through metacognitive evaluations, individuals assess their own cognitive operations with respect to their current goals. We have previously shown that non-verbal social cues spontaneously influence these evaluations, even when the cues are unreliable. Here, we explore whether a belief about the reliability of the source can modulate this form of social impact. Participants performed a two-alternative forced choice task that varied in difficulty. The task was followed by a video of a person who was presented as being either competent or incompetent at performing the task. That person provided random feedback to the participant through facial expressions indicating ag…

Combined strength and endurance exercise induced fatigue and recovery

2012

Muscular fatigue is usually defined as the inability to maintain a given exercise intensity or adequate muscle force and therefore maximal isometric force, neural activation and fast force production capacity have often used determinants of acute fatigue. The purpose of the present study was to measure the acute effects of combined strength and endurance exercise on force production, muscle activation and work economy. In addition this study investigated the rate of recovery comparing the active and passive recovery models and the association of the initial fitness levels of subjects. 16 (27 ± 4 years old) male reservists performed combined strength (5x10x70%RM leg-press) and endurance (5x1…

Experimental study of electron transport in mesoscopic carbon based nanostructures

2012

In this thesis we have studied experimentally electronic transport in mesoscopic hybrid polypyrrole-gold devices and single multiwalled carbon nanotube devices. A novel fabrication technique for mesoscopic conducting hybrid polymer-gold films has been developed. The hybrid polymer-gold films have been fabricated by electrochemical deposition of polypyrrole on a gold nanoisland layer. Temperature dependence of conductance show that the dominant transport mechanism in the polypyrrole-gold films is variable range hopping in the temperature range from 20 K to 300 K. At very low temperature strong nonlinearities in the field dependent conductance are observed. The field dependence follows a phen…

Linking employer branding orientation and firm performance: Testing a dual mediation route of recruitment efficiency and positive affective climate

2019

Faced with competitive labor markets, firms increasingly use employer branding to build a qualified workforce and engage their employees. However, our understanding of the impact of employer branding orientation on firm performance and the theoretical firm‐level mechanisms underlying this potential impact is very limited. To address this gap, we integrate brand marketing theory with human resource management (HRM) research to develop a model explicating how employer branding orientation is linked to firm performance through a dual route by enhancing both recruitment efficiency (i.e., external route: applicants) and positive affective climate (i.e., internal route: incumbent employees). The …

Coarse-Graining Intermolecular Interactions in Dispersions of Highly Charged Colloids

2012

International audience; Effective pair potentials between charged colloids, obtained from Monte Carlo simulations of two single colloids in a closed cell at the primitive model level, are shown to reproduce accurately the structure of aqueous salt-free colloidal dispersions, as determined from full primitive model simulations by Linse et al. (Linse, P.; Lobaskin, V. Electrostatic Attraction and Phase Separation in Solutions of Like-Charged Colloidal Particles. Phys. Rev. Lett.1999, 83, 4208). Excellent agreement is obtained even when ion-ion correlations are important and is in principle not limited to spherical particles, providing a potential route to coarse-grained colloidal interactions…

El régimen jurídico de la mediación civil y mercantil en conflictos transfronterizos en españa tras la ley 5/2012, de 6 de julio**Artículo recibido e…

2013

ResumenEl presente artículo analiza en profundidad la regulación que la Ley 5/2012, de 6-7, incorpora de la mediación transfronteriza, abordando diversos aspectos esenciales de ésta. La regulación del acuerdo de sometimiento a mediación, el papel de los mediadores, su formación y reconocimiento de su condición, la eventual ley aplicable al fondo del litigio o la eficacia alcanzada por el acuerdo concluido por las partes son, en este sentido, algunos de los aspectos clave estudiados. El análisis realizado pone de manifiesto el logro intrínseco que la Ley supone y su relevancia a la hora de fomentar el recurso a la institución en España, a la vez, que refleja la necesidad de que la Ley se apl…

Enforcing WTO Law

2017

This contribution analyses the difference between the enforcement system provided for by the European Union legal system and the one set up by the World Trade Organisation. The reciprocal and bilateral nature of the WTO obligations and the possibility for the parties to a dispute to have recourse to negotiation (in ways not always foreseen and regulated by the Dispute Settlement Understanding) in order to resolve the issue of implementation in the post-adjudication phase of the dispute settlement procedure are features that by-and-large differentiate the WTO legal system from that of the EU and also explains the differences between the remedies provided for by the two systems.

Aging of the musculoskeletal system: How the loss of estrogen impacts muscle strength.

2019

Skeletal muscle weakness occurs with aging and in females this is compounded by the loss of estrogen with ovarian failure. Estrogen deficiency mediates decrements in muscle strength from both inadequate preservation of skeletal muscle mass and decrements in the quality of the remaining skeletal muscle. Processes and components of skeletal muscle that are affected by estrogens are beginning to be identified. This review focuses on mechanisms that contribute to the loss of muscle force generation when estrogen is low in females, and conversely the maintenance of strength by estrogen. Evidence is accumulating that estrogen deficiency induces apoptosis in skeletal muscle contributing to loss of…

Interface behaviour of bonded CFRP-Calcarenite stone joints

2010

This paper presents the results of an experimental study investigating the interface behaviour between calcarenite stone and Carbon Fibre Reinforced Polymer (CFRP) reinforcement. The analysis of the results has allowed to deduce the local behaviour at the interface, which can be modelled by means of a bi-linear shear stress-slip law, according to several codes. The experimental investigation was carried out on specimens subjected to double shear pulling tests by varying the bond length of the CRFP strips. Tests enabled determination of the bond strength of the joint and the effective bond length. The parameters of the stress-slip law were calibrated on the experimental results in order to c…
