Le propos de cet article est de rendre compte des développements de la théorie de l’énonciation à la suite de la proposition d’Emile Benveniste d’étendre ce concept à la musique et à d’autres langages non verbaux. Un retour sur cette question se révèle aujourd’hui nécessaire pour plusieurs raisons. Certaines sont internes à la discipline et aux sciences du langage — la légitimité du visuel en tant que langage —, d’autres sont extra-disciplinaires, venant surtout des sciences de la communication et de la philosophie de l’art. Nous aborderons ici deux questions fondamentales concernant l’énonciation dans le visuel, étroitement liées entre elles. La première concerne la subjectivité inscrite dans l’image et sera approchée via la notion d’énonciation énoncée (personne/espace/temps). L’analyse énonciative de l’énoncé visuel vise en effet à décrire « d’où l’on voit », à savoir les points de vue à partir desquels l’image a été conçue et demande à être saisie par le regard de l’observateur. La deuxième question concerne la notion de métalangage. Comme l’a affirmé Jacques Fontanille, l’énonciation est « un métalangage "descriptif" car, en prédiquant l’énoncé, elle affiche sa propre activité, elle la code et en fait un événement sensible ou observable » (Sémiotique du discours, 2003, p. 283). Une première interrogation émerge alors : peut-on parler de métalangage dans le cadre du visuel, où il est d’ailleurs déjà difficile de repérer une véritable langue visuelle, dotée d’un alphabet de signes disjoints et d’une grammaire figée ?

Hydro-Québec has a long interest in on-line Dynamic Security Assessment (DSA) driven by its challenging system dynamics. Presently, off-line calculated security limits are combined with an on-line monitoring system. However, new developments in dynamic simulation enable real-time or near-real-time DSA calculations and transfer limits determination. In this paper, the domain-decomposition-based algorithm implemented in the simulator RAMSES is presented, along with techniques to accelerate its sequential and parallel executions. RAMSES exploits the localized response to disturbances and the timescale decomposition of dynamic phenomena to provide sequential acceleration when the simulation is performed on a single processing unit. Additionally, when more units are available, the parallelization potential of domain-decomposition methods is exploited for further acceleration. The algorithm and techniques have been tested on a realistic model of the Hydro-Québec system to evaluate the accuracy of dynamic responses and the sequential and parallel performances. Finally, the real-time capabilities have been assessed using a shared-memory parallel processing platform. [less ▲]

Customers often experience intense emotions during service encounters. Their perceptions of how well contact employees demonstrate emotional competence in emotionally charged service encounters can affect their service evaluations and loyalty intentions. Previous studies examining employees’ potential to behave in emotionally competent ways (i.e., employee emotional intelligence [EEI]) have used self- or supervisor-reported scales to predict customer outcomes, presenting EEI as stable and independent of the context. However, service firms should be more concerned with the actual display of emotionally competent behaviors by employees (employee emotional competence [EEC]), because employee behaviors vary across encounters. Moreover, a customer perspective of EEC is useful as customer perceptions of employee performance are crucial predictors of satisfaction and loyalty. Therefore, this study proposes a conceptualization and operationalization of EEC in a service encounter context. On the basis of a comprehensive literature review and in-depth interviews, the authors develop a scale to capture customer-perceived EEC, defined as an employee’s competence in perceiving, understanding, and regulating customer emotions during a discrete service encounter. The scale achieves good reliability and validity. Researchers can use it to explore the role of EEC in service contexts; managers can employ the scale to diagnose EEC and improve customers’ service encounter experiences. [less ▲]

The activity of bacterial strains significantly influences the quality and the taste of vinegar. Previous studies of acetic acid bacteria have primarily focused on the ability of bacterial strains to produce high amounts of acetic acid. However, few studies have examined the production of gluconic acid during acetous fermentation at high temperatures. The production of vinegar at high temperatures by two strains of acetic acid bacteria isolated from apple and cactus fruits, namely AF01 and CV01, respectively, was evaluated in this study. The simultaneous production of gluconic and acetic acids was also examined in this study. Biochemical and molecular identification based on a 16s rDNA sequence analysis confirmed that these strains can be classified as Acetobacter pasteurianus. To assess the ability of the isolated strains to grow and produce acetic acid and gluconic acid at high temperatures, a semi-continuous fermentation was performed in a 20-L bioreactor. The two strains abundantly grew at a high temperature (41°C). At the end of the fermentation, the AF01 and CV01 strains yielded acetic acid concentrations of 7.64% (w/v) and 10.08% (w/v), respectively. Interestingly, CV01 was able to simultaneously produce acetic and gluconic acids during acetic fermentation, whereas AF01 mainly produced acetic acid. In addition, CV01 was less sensitive to ethanol depletion during semi-continuous fermentation. Finally, the enzymatic study showed that the two strains exhibited high ADH and ALDH enzyme activity at 38°C compared with the mesophilic reference strain LMG 1632, which was significantly susceptible to thermal inactivation.

Serine/Arginine-rich (SR) proteins are essential nucleus-localized splicing factors. Our prior studies showed that Arabidopsis RSZ22, a homolog of the human SRSF7 SR factor, exits the nucleus through two pathways, either dependent or independent on the XPO1 receptor. Here, we examined the expression profiles and shuttling dynamics of the Arabidopsis SRSF1 subfamily (SR30, SR34, SR34a and SR34b) under control of their endogenous promoter in Arabidopsis and in transient expression assay. Due to its rapid nucleocytoplasmic shuttling and high expression level in transient assay, we analysed the multiple determinants that regulate the localisation and shuttling dynamics of SR34. By site-directed mutagenesis of SR34 RNA-binding sequences and RS domain, we further show that functional RRM1 or RRM2 are dispensable for the exclusive protein nuclear localization and speckle-like distribution. However, mutations of both RRMs induced aggregation of the protein whereas mutation in the RS domain decreased the stability of the protein and suppressed its nuclear accumulation. Furthermore, the RNA-binding motif mutants are defective for their export through the XPO1 (CRM1/Exportin-1) receptor pathway, but retain nucleocytoplasmic mobility. We performed a yeast two hybrid screen with SR34 as bait and discovered SR45 as a new interactor. SR45 is an unusual SR splicing factor bearing two RS domains. These interactions were confirmed in planta by FLIM-FRET and BiFC and the roles of SR34 domains in protein-protein interactions were further studied. Altogether, our report extends our understanding of shuttling dynamics of Arabidopsis SR splicing factors [less ▲]

Adopting an intensive qualitative case study approach two local authorities, the London Borough of Ealing and Bristol City Council, are considered in detail. Ealing represents a suburban area that experienced concurrently significant soft densification and de-conversion of existing stock in the period 2001 to 2011, whilst Bristol over the same period experienced a high level of housing growth.

In finite element simulations of orthodontic tooth movement, one of the challenges is to represent long term tooth movement. Large deformation of the periodontal ligament and large tooth displacment due to bone remodelling lead to large distortions of the finite element mesh when a Lagrangian formalism is used. We propose in this work to use an Arbitrary Lagrangian Eulerian (ALE) formalism to delay remeshing operations. A large tooth displacement is obtained including effect of remodelling without the need of remeshing steps but keeping a good-quality mesh. Very large deformations in soft tissues such as the periodontal ligament is obtained using a combination of the ALE formalism used continuously and a remeshing algorithm used when needed. This work demonstrates that the ALE formalism is a very efficient way to delay remeshing operations. [less ▲]
