Conception multimédia des supports et structuration textuelle : application à différents corpus textuels
1998
Rapport de contrat CNET Étude socio-cognitive des usages du multimédia; La conjecture est faite que la structuration d'un texte technique fondée sur les valeurs illocutoires des unités textuelles pourrait favoriser son traitement. Cette recherche analyse la distinction du second plan par rapport au premier plan (valeur de «moindre importance»). Dans le cadre de cette distinction, une typologie des unités textuels de textes techniques est proposée et sa réalité psychologique évaluée expérimentalement. On montre que le repérage des valeurs illocutoires des unités textuelles sur la seule base du langage est difficile. Deux expériences étudient alors, sur papier et sur écran, l'effet du marquag…
Personal use of technology at work : a literature review and a theoretical model for understanding how it affects employee job performance
2021
Employee personal use of technology at work (PUTW)—defined as employees’ activities using organisational or personal IT resources for non-work-related purposes while at work—is increasingly common in organisations. Our review of existing PUTW studies (n = 137) suggests that previous studies widely discussed PUTW outcomes, antecedents, and policies. The literature review also indicates that previous studies have proposed opposing viewpoints regarding the effect of PUTW on employee job performance, but few studies offered empirical evidence. Consequently, the conditions under which PUTW can increase or decrease employee job performance have not been discussed. We develop a theoretical model (…
A different glimpse into mobilities: On the interrelations between daily spatial mobility and social mobility
2017
We explore the link between daily spatial mobility and social mobility, taking changes in the contemporary labor market and family as examples. We propose a new theoretical approach to mobility that is defined as a productive force of social labor. Analyzing the relationship between daily spatial mobility and social mobility, we show that spatial mobility has become a strategy of compensation for the lack of social mobility. Explanations for the increase in daily spatial mobility are also provided. Lastly, we reveal how spatial mobility has the capacity to produce major social change, taking the family as an example. peerReviewed
Valoración de las necesidades de información de los médicos: publicaciones en el periodo 1990-1998 y estudio de un caso
2000
Los estudios de necesidades de información aportan una metodología con lo cual investigar, de manera sistemática, las características de los usuarios con relación a la información que necesitan para el desarrollo de su trabajo. Igualmente proporcionan criterios objetivos para tomar decisiones a la hora de planificar nuevos sistemas de información o adecuar los ya existentes. Esta tesis ha profundizado en los estudios de necesidades de información en el entorno hospitalario desde dos puntos de vista. Por una parte, se ha establecido un marco teórico de referencia que guíe las investigaciones en este campo. Para ello se ha buscado exhaustivamente la información publicada sobre la materia apor…
Un témoignage sensible, la parole du chrétien selon le pape François
2016
International audience; Si le pape François montre un intérêt soutenu pour les médias afin d’informer le plus largement de l’actualité de l’Église catholique, il s’en remet à d’autres modalités pour transmettre la Parole. Le chrétien annonce le message à travers sa manière d’être chrétien ; c’est tout le sens de la notion de « témoignage » dans l’acte de dire la Parole. À partir d’un corpus de textes pontificaux du pape François, l’intention de cette réflexion est de questionner cette manière chrétienne d’être au monde, plus précisément dans l’espace public, et d’être à l’autre en explorant conjointement deux voies : (i) le soubassement sensible d’une pratique énonciative faite de comportem…
Age of Information Based URLLC-enabled UAV Wireless Communications System
2022
This paper considers an unmanned aerial vehicles (UAV) communication network, where UAV operate as an aerial mobile relay between a source and a destination of the network. To capture the “timelines” of the received information at the destination node, a new performance metric named age of information (AoI) is considered. In addition, a short packet communication scheme maintains low latency in the proposed UAV wireless communication system. The finite block-length theory investigates the performances of short packet communications scheme in the UAV-assisted wireless communications system. In this paper, the Average Age of Information (AAoI) is estimated by applying the Stochastic Hybrid Sy…
Supportive Communication in the Workplace
2019
Supportive communication is a form of social interaction that produces resources with which to solve situational problems and manage emotional strain. Through the management of uncertainty, supportive communication enhances the perception of personal control over life events and strengthens the perception of acceptance. It is enacted in the seeking of support, in providing support, and in supportive listening as a form of emotional and informational support. In the workplace, supportive communication is crucially important: It promotes productive work and employees’ well-being as well as job satisfaction and engagement in the organization. This chapter presents the foundations of supportive…
Compensation of Nonlinearity of Voltage and Current Instrument Transformers
2019
This paper aims at characterizing and improving the metrological performances of current and voltage instrument transformers (CTs and VTs) in harmonic measurements in the power system. A theoretical analysis is carried out to demonstrate that, due to the iron core nonlinearity, CT and VT output signal is distorted even when the input signal is a pure sine wave. Starting from this analysis, a new method for CT and VT characterization and compensation is proposed. In a first step, they are characterized in sinusoidal conditions and the harmonic phasors of the distorted output are measured; in the second step, these phasors are used to compensate the harmonic phasors measured in normal operati…
Observation of the Early Structural Changes Leading to the Formation of Protein Superstructures.
2014
Formation of superstructures in protein aggregation processes has been indicated as a general pathway for several proteins, possibly playing a role in human pathologies. There is a severe lack of knowledge on the origin of such species in terms of both mechanisms of formation and structural features. We use equine lysozyme as a model protein, and by combining spectroscopic techniques and microscopy with X-ray fiber diffraction and ab initio modeling of Small Angle X-ray Scattering data, we isolate the partially unfolded state from which one of these superstructures (i.e., particulate) originates. We reveal the low-resolution structure of the unfolded state and its mechanism of formation, hi…
: Un dialogue interculturel ?
2008
National audience; L'artisan nous intéresse ici comme un acteur des savoirs. Notre position universitaire n'est pas neutre, il existe une tension entre ces deux mondes dont le chercheur doit tenir compte : comment se présente l'artisan comme acteur des savoirs dans le regard des chercheurs ? Quel est le regard des artisans sur eux-mêmes et par contraste sur les chercheurs en sciences humaines et sociales comme acteurs des savoirs ? Nous proposons un jeu de miroir sur ces représentations sociales, avant d'examiner deux formes de médiation possibles. Ces expériences nous invitent à envisager un rapport aux savoirs repéré dans la figure hybride de "l'artisan-chercheur".
