Écrire l’hommage : le cas de la Fête des Lumières en 2015 sur Twitter
Authors: Piquer-Louis Oriane 
Published: August 2019

Annulée en 2015 suite aux attentats survenus le 13 novembre à Paris, la Fête des Lumières est transformée par la ville de Lyon en un hommage aux victimes. Cet article porte sur un corpus de messages publiés le 8 décembre 2015 sur Twitter, et en particulier sur les photographies qui les accompagnent. Forte d’une méthodologie hybride, alliant les sciences de l’informatique et les sciences de l’information et de la communication, cette étude met en lumière les opérations de médiation qui permettent à l’événement qui a lieu d’être documenté par le public. Les publications sur le réseau social opèrent une multitude d’écritures qui transcrivent à plusieurs reprises l’hommage célébré ce soir-là. Autant de passages et de médiatisations qui enrichissent le message et façonnent son existence particulière en société.
Écritures éphémères, écritures fragmentaires, écritures ordinaires
Authors: Artières Philippe , Bazin Maëlle , Lambert Frédéric 
Published: August 2019

Philippe Artières est un historien français, directeur de recherche au CNRS au sein de l’Institut interdisciplinaire d’anthropologie du contemporain (IIAC) à l’École des hautes études en sciences sociales et président du centre Michel Foucault. Spécialiste des écritures ordinaires du xix e et xx e siècle, ses recherches portent notamment sur la surveillance des écrits dans l’espace public. Ses nombreuses implications pour le cinquantième anniversaire de Mai 68 constituent un point de départ opportun pour interroger le rapport entre écriture et événement. L’entretien se concentre sur son parcours de recherche, son intérêt pour les écritures éphémères et surtout celles délaissées, oubliées voire rejetées, ainsi que sur la question de l’attention sociale portée à ces écrits.
La « brève de consommation » : sémiotique d'un genre journalistique entre information et promotion
Authors: Desnica Mirta 
Published: August 2019

Cet article a pour objet un genre de la presse écrite caractérisé par le fait de coupler l'information pour la consommation avec l'incitation à la consommation, et que l'auteure propose d'appeler « brève de consommation ». Ses propriétés sémiotiques et pragmatiques sont décrites à partir d'un corpus de presse féminine, dont ce genre textuel est emblématique. Il est ensuite étudié au regard des normes d'écriture journalistique telles qu'elles sont formulées dans les manuels de journalisme. Participant à la promotion de produits et de marques, ces articles apparaissent comme un lieu de rencontre entre le discours d'information journalistique et le discours marchand et comme un effet du « journalisme de marché ».
Les figures d'autorité dans la publicité testimoniale
Authors: Petters Lorreine 
Published: August 2019

En contexte publicitaire, les figures d'autorité restituent parfois des vécus présumés en attestant de la vérité de leurs paroles. On associera une telle mise en scène à la notion de « publicité testimoniale ». Cet article s'interroge sur la définition même de la « publicité testimoniale », tout en s'intéressant aux individus capables d'y faire autorité et à leur prise de parole dans le cadre des messages testimoniaux. En identifiant trois figures d'autorité principales – la célébrité, la « personnalité d'entreprise » et la « personnalité du web » –, l'objectif est de comprendre la manière dont ces figures stimulent l'adhésion des interlocuteurs aux messages diffusés.
Blogs d'écrivain et écrivains-blogueurs : Internet et l'hybridation de la littérature
Authors: Ruiz Ugo 
Published: August 2019

Cet article s'intéresse aux reconfigurations du domaine littéraire sur Internet. Entre ce qu'il propose d'appeler le « régime éditorial traditionnel » et le « nouveau régime éditorial », l'auteur établit une distinction qui est mise en perspective par l'étude des blogs de trois écrivains reconnus. Cette pratique littéraire du blog d'écrivain semble symptomatique d'un phénomène que l'auteur propose de désigner par le terme d'hybridation, en ce qu'il provient de la coexistence des deux régimes éditoriaux en tension. Au-delà du statut des écrivains-blogueurs, cette hybridation littéraire est la manifestation d'un changement plus radical qui engage une réflexion sur le pouvoir de la littérature et sur la notion d'autorité.
Le design de l'information : textualisation, documentarisation, auctorialisation
Authors: Zacklad Manuel 
Published: August 2019

Dans cet article consacré au design de l'information, l'auteur propose une définition de l'information ancrée dans une vision anthropologique de la communication et présente l'approche ternaire de l'information de M. Buckland qui est en phase avec sa typologie. Dans un deuxième temps, un retour sur la notion de dispositif permet d'introduire les dispositifs d'information et de communication et d'en donner quelques exemples. Cette articulation permet, dans une troisième partie, d'aborder le design de l'information consignée dans toute sa richesse et sa complexité, combinant les problématiques de la textualisation, de l'auctorialisation et de la documentarisation.
L'agir documentaire, une politique du détail. À partir du cas de #SoyonsHumains
Authors: Bonaccorsi Julia 
Published: August 2019

Le document est‑il une pratique politique et à quelles conditions peut‑il servir une critique sociale ? Cet article croise deux entrées sur le projet documentaire, comme processus et comme poétique. L'exploration sémio-discursive de la campagne de documentation photographique des « mobiliers urbains anti-SDF » initiée en décembre 2017 par la Fondation Abbé Pierre et Emmaüs Solidarité à partir du hashtag #SoyonsHumains permet de nourrir empiriquement la réflexion et de rendre compte du sens social du document dans la mise en discours et en visibilité de la « cause de l'autre ».
Le document dans une pragmatique sociale de l'information
Authors: Lehmans Anne , Liquète Vincent 
Published: August 2019

En quoi l'analyse des pratiques sociales et professionnelles d'information peut‑elle enrichir les définitions du document telles qu'elles sont posées par les sciences de l'information et de la communication et renouveler leur approche ? À partir de plusieurs contextes d'observation dans le cadre de projets de recherche, la classe, des espaces professionnels, l'atelier, on constate que les attentes sociales et l'activité font du document un espace co-construit, structurant l'organisation de l'information et sa gestion. Le document, en tant qu'espace dialogique, devient alors un moyen de formalisation des activités en jeu au regard des positionnements, des représentations et des finalités projetées. Sur la base de ces recherches, il est permis d'envisager un complément aux définitions actuelles du document, qui ne se focalise pas seulement sur son contenu mais sur les modalités de son élaboration et sur son rôle dans la construction des apprentissages.
Vieillir, cette affreuse chose. Les autoportraits de Roman Opalka et Maria Lassnig
Authors: Beyaert-Geslin Anne 
Published: August 2019

Comme l'a indiqué naguère Locke, les signes et les images nous sont indispensables pour mémoriser et partager les expériences. En mettant en discours ce qui resterait sans eux, insaisissables, ils accomplissent la part positive d'une médiation. C'est ainsi qu'ils saisissent le temps au passage et le mettent en discours. L'article compare les autoportraits photographiques de Roman Opalka et les autoportraits peints par Maria Lassnig avec une méthodologie sémiotique pour comprendre comment, en faisant signifier des traces, ils relèvent à la fois le défi de la représentation du vieillissement et le partage de son expérience. Ceci permet de préciser les contributions du médium à cet « effet de temps » et de définir deux formes de vie contraires.
Processen van place-making door talige praktijken in Tilburg, Heerlen en Genk
Authors: Cornips Leonie , Marzo Stefania , Swanenberg Jos 
Published: August 2019

Samenvatting
In dit artikel tonen we aan de hand van kwalitatieve data aan hoe talige praktijken met sprekers en artiesten uit drie steden in de periferie van Nederland en België, namelijk Tilburg, Heerlen en Genk een lokale identiteit construeren en reproduceren en hoe op die manier het besef van lokale eigenheid tot stand komt. We laten zien dat in deze drie steden artiesten en sprekers aan de hand van geënsceneerde en gemediatiseerde taalprakijken bewust nieuwe lokale identiteiten construeren. In de drie gevallen gaat het om hybride of heterogene taalprakijken, waarbij het Nederlands of lokale dialectale elementen gecombineerd worden met elementen uit andere aanwezige (contact)talen (zoals het Surinaams of het Italiaans). Bovendien worden deze taalpraktijken in Tilburg en Heerlen, maar ook – hoewel in mindere mate – voor Genk, via parodie verspreid, versterkt en vernieuwd.
Samson's Bondage
Authors: Shullenberger William 
Published: August 2019

ABSTRACT
The riddler of the Book of Judges, Samson, is a riddle himself, in the Bible and in Samson Agonistes. Samson's career can be mapped out in three stages, distinguished by Samson's different experiences of bondage. In his boisterous heyday, Samson liked to get tied up, burst free of constraints, and erupt into violence. In the time frame of Milton's drama, Samson finds himself literally blinded, and physically, psychologically, and politically reduced to bondage, to the bestial repetition of slave labor, publicly humiliated by the gazes and taunts of passersby. Søren Kierkegaard's analysis of the existential dilemma that Abraham faces provides by narrative analogy an interpretive key to the riddle of Samson's various types of bondage. The final phase of bondage for Milton's Samson is the appalling yet liberatory one in which he becomes, and acts, like Kierkegaard's Abraham, a blindly free agent because of his belief in the absurd.

Published: August 2019

This study was conducted to determine the root tolerance and biochemical responses of four Chinese Lactuca sativa L. genotypes (Lüsu, Lümeng, Yidali and Anyan) to cadmium (Cd2+) stress. Twenty-eight days old seedlings were exposed to Hoagland’s nutrient solution supplied with or without 100 µM CdCl2 and monitored for seven days in a climate controlled room. The 100 µM CdCl2 significantly (P < 0.001) decreased all the root morphological indexes of the four genotypes. However, Yidali, which possessed the smallest root system, exhibited greater root tolerance to Cd2+ by having the highest tolerance indexes for root volume (46%), surface area (61%), projected area (74%) and numbers of root forks (63%) and root tips (58%). Moreover, Cd2+ stress also caused increases in H2O2 contents in the roots but the increase was least in Yidali which showed greater root tolerance to Cd2+stress. The effect of Cd2+ stress on the contents of hormones in the roots depended on the genotypes. Under Cd2+ stress, abscisic acid correlated positively with indole-3-acetic acid (r = 0.669*), gibberellic acid (r = 0.630*) and cytokinin (r = 0.785**). The antioxidant enzyme activities and proline responses of the four genotypes to Cd2+ stress were similar. The SOD activity was decreased whiles the CAT and POD activities, as well as the contents of proline increased in all the genotypes under the stress condition. These results suggest that lettuce genotypes with smaller root systems could be more tolerant to Cd2+ stress compared to those with larger root systems.

AbstractBackgroundGray matter (GM) pathology is closely associated with physical and cognitive impairment in persons with multiple sclerosis (PwMS). Similarly, serum neurofilament light chain (sNfL) levels are related to MS disease activity and progression.ObjectivesTo assess the cross–sectional and longitudinal associations between sNfL and MRI–derived lesion and brain volume outcomes in PwMS and age–matched healthy controls (HCs).Materials and MethodsForty‐seven HCs and 120 PwMS were followed over 5 years. All subjects underwent baseline and follow–up 3T MRI and sNfL examinations. Lesion volumes (LV) and global, tissue–specific and regional brain volumes were assessed. sNfL levels were analyzed using single molecule array (Simoa) assay and quantified in pg/mL. The associations between sNfL levels and MRI outcomes were investigated using regression analyses adjusted for age, sex, baseline disease modifying treatment (DMT) use and change in DMT over the follow‐up. False discovery rate (FDR)–adjusted q‐values <0.05 were considered significant.ResultsIn PwMS, baseline sNfL was associated with baseline T1‐, T2‐ and gadolinium‐LV (q = 0.002, q = 0.001 and q < 0.001, respectively), but not with their longitudinal changes. Higher baseline sNfL levels were associated with lower baseline deep GM (β = −0.257, q = 0.017), thalamus (β = −0.216, q = 0.0017), caudate (β = −0.263, q = 0.014) and hippocampus (β = −0.267, q = 0.015) volumes. Baseline sNfL was associated with longitudinal decline of deep GM (β = −0.386, q < 0.001), putamen (β = −0.395, q < 0.001), whole brain (β = −0.356, q = 0.002), thalamus (β = −0.272, q = 0.049), globus pallidus (β = −0.284, q = 0.017), and GM (β = −0.264, q = 0.042) volumes. No associations between sNfL and MRI–derived measures were seen in the HCs.ConclusionHigher sNfL levels were associated with baseline LVs and greater development of GM atrophy in PwMS.
Magnetic Liquid Metal (Fe‐EGaIn) Based Multifunctional Electronics for Remote Self‐Healing Materials, Degradable Electronics, and Thermal Transfer Printing
Authors: Guo Rui , Sun Xuyang , Yuan Bo , Wang Hongzhang , Liu Jing 
Published: August 2019

AbstractFlexible materials with the ability to be bent, strained, or twisted play a critical role in soft robots and stretchable electronics. Although tremendous efforts are focused on developing new stretchable materials with excellent stability, inevitable mechanical damage due to long term deformation is still an urgent problem to be tackled. Here, a magnetic healing method based on Fe‐doped liquid metal (Fe‐GaIn) conductive ink via a noncontact way is proposed. Further, multifunctional flexible electronics are designed with combined performances of superior remote self‐healing under magnetic field, water‐degradable, and thermal transfer printing, which attribute to three parts of the materials including Fe‐GaIn conductive ink, degradable PVA substrate, and adhesive fructose. The as‐made light emitting diodes (LED) circuit is demonstrated with both structural and functional repairing after single or multipoint damage. The self‐healing time from multipoint damage is pretty fast within 10 s. Due to the water‐soluble PVA film, the recycling process is simple via immersing into water. Through heating, the electric circuit on fructose can be transferred to other flexible substrate with high efficiency, which broadens the practical applications of the present system. The novel and multifunctional electronics hold great promise for self‐healing electronics, transient electronics, and soft robots.
Supply chain networks servicing upstream operations in oil and gas fields after the shale revolution
Authors: Montagna Agustín F. , Cafaro Diego C. 
Published: August 2019

AbstractThe recent irruption of shale resources in the oil and gas (O&G) industry has dramatically changed the paradigm for managing upstream operations. Unconventional production is largely driven by drilling new wells, yielding a much larger scale of material and service flows that need to be efficiently planned. This article presents an optimization framework for the design of integrated supply chain networks (SCNs) servicing upstream operations. Novel aspects addressed in this work are the integrated planning of material and service supplies; the economies of scale in operating, transportation and capital expenditures; the concept of waiting cost to quantify production losses; and the reverse flow of materials within closed‐loop supply chains. The merits of the proposed approach are assessed through real‐world case studies from the Argentine O&G industry. Optimal designs yield significant cost savings and confirm that the integrated planning of the SCN is critical for O&G operators after the shale revolution.
Artificial intelligence: Implications for the future of work
Authors: Howard John 
Published: August 2019

Artificial intelligence (AI) is a broad transdisciplinary field with roots in logic, statistics, cognitive psychology, decision theory, neuroscience, linguistics, cybernetics, and computer engineering. The modern field of AI began at a small summer workshop at Dartmouth College in 1956. Since then, AI applications made possible by machine learning (ML), an AI subdiscipline, include Internet searches, e‐commerce sites, goods and services recommender systems, image and speech recognition, sensor technologies, robotic devices, and cognitive decision support systems (DSSs). As more applications are integrated into everyday life, AI is predicted to have a globally transformative influence on economic and social structures similar to the effect that other general‐purpose technologies, such as steam engines, railroads, electricity, electronics, and the Internet, have had. Novel AI applications in the workplace of the future raise important issues for occupational safety and health. This commentary reviews the origins of AI, use of ML methods, and emerging AI applications embedded in physical objects like sensor technologies, robotic devices, or operationalized in intelligent DSSs. Selected implications on the future of work arising from the use of AI applications, including job displacement from automation and management of human‐machine interactions, are also reviewed. Engaging in strategic foresight about AI workplace applications will shift occupational research and practice from a reactive posture to a proactive one. Understanding the possibilities and challenges of AI for the future of work will help mitigate the unfavorable effects of AI on worker safety, health, and well‐being.
Synthesis of noble‐metal‐free ternary K7HNb6O19/Cd0.5Zn0.5S/g‐C3N4 tandem heterojunctions for efficient photocatalytic performance under visible light

Published: August 2019

Exploring noble‐metal‐free, highly active and durable catalysts is vital to get to grips with the energy and environmental issues. Herein, we first dexterously design and synthesize a class of ternary Nb6/CZS/g‐CN photocatalysts for the removal of hexavalent chromium Cr (VI) and organic dye pollutant (MO) from wastewater under visible‐light irradiation. A heterojunction Nb6–1/CZS/g‐CN loaded with 0.01 g K7HNb6O19 showed excellent photocatalytic performance, with the MO photodegradation efficiency of 94% in 1 h and the Cr (VI) (150 mg/l) photoreduction efficiency as high as 91% in 2 hr. The main active species were deemed to be O2.‐. Additionally, the as‐prepared ternary heterojunction exhibits superior hydrogen evolution reaction (HER) rate. A heterojunction Nb6–4/CZS/g‐CN loaded with 0.5 g K7HNb6O19 exhibited the highest H2 evolution rate as high as 1777.86 μmol h−1 g−1 under visible‐light illumination, which is increased to 5.7 and 2.7 times that of bare CZS and biphase heterojunction CZS/g‐CN. These findings afford a new class of promising low‐cost photocatalyst bodying for its huge potential value in sustainable energy development and wastewater treatment.
Robust output‐based controller design for enlarging the region of attraction of input saturated linear systems
Authors: Mera Manuel , Salgado Iván , Chairez Isaac 
Published: August 2019

AbstractThe aim of this study was to design a constrained robust output feedback control strategy for stabilizing linear systems affected by uncertainties and output perturbations. The input is constrained by a saturation function. A classical Luenberger observer reconstructed the states from output observations. The state feedback control employed the estimated states given by the observer. This work proposed a Barrier Lyapunov Function (BLF) to manage the saturation problem in the control input. Moreover, an extended version of the attractive ellipsoid method (AEM) characterized the zone of convergence due the presence of perturbations in the output. A convex optimization procedure, formulated as a set of matrix inequalities, yielded the control parameters and the region of attraction for the close‐loop system as well as a minimal ultimately bounded set for the system trajectories. Numerical simulations supported the theoretical results formulated in this study.
Versatile Synthesis of Vanadium(III, IV, V) Oxides@Reduced Graphene Oxide Nanocomposites and Evaluation of their Lithium and Sodium Storage Performances
Authors: Liu Xuelian , Depaifve Sébastien , Leyssens Tom , Hermans Sophie , Vlad Alexandru 
Published: August 2019

AbstractVanadium oxides (VOx) have been extensively investigated over the past years as promising electrode materials for alkali ion batteries owing to their rich and interesting electrochemical properties. Further improvements on electrochemistry of VOx materials have been possible by working at the nanoscale as well as by realising hierarchical composites with various carbon allotropes. However, the nanocomposite synthesis methods are not always efficient, nor green, requiring either expensive precursors, extended synthesis time or harmful reagents. Herein, we report on rapid and environmentally friendly synthesis methods of a library of VOx@rGO composites via impregnation and hydrothermal protocols using a cheap and commercially available V2O5 precursor. Different oxidation states, crystalline phases and nanoscale morphologies can be reproducibly accessed and their physico‐chemical properties have been characterized. The electrochemical properties (lithium and sodium ion storage) of the synthesized VOx@rGO nanocomposites and phases have been critically inter‐compared between these but also with respect to commercial (CM) VOx‐based electrodes. Whereas nanostructuring is found to impact the power‐rate performances, the amount of stored charge and the cycling stability are sensitively dependent on the cycling potential window, while being minorly affected by the morphology and synthesis method. The composites are also found to exhibit different electrochemistry for sodium storage, with more sloping potential profiles. Peculiarly, the synthesized V2O3@rGO composite shows no signs of electrochemical activity pointing towards the electrochemical inertness of this particular V2O3 composite and phase. This work could serve as reference for future developments on this class of important battery materials as it is one of the few studies describing a comprehensive and comparative study of several different influential parameters on the electrochemical behaviour of vanadium oxides in different oxidation states, crystalline phases and morphologies.
