L’avenir de la librairie est devant elle
Authors: Rimaud Mathilde 
Published: January 2020

Le marché du livre français se distingue de celui d’autres pays par la présence d’un réseau encore dense de librairies indépendantes, dont le nombre diminue régulièrement mais reste néanmoins important, sur un marché du livre par ailleurs atone. Non, la lecture n’est pas morte, différentes études en témoignent ; non, Internet, et au premier chef le dragon Amazon, ne domine pas encore tout le marché, bien que les ventes en ligne bousculent les différents canaux depuis une vingtaine d’années. Comment expliquer la relative résistance des librairies indépendantes, quand on constate par ailleurs les stratégies de fusion des plus grandes structures (Furet du Nord/Decitre, Fnac/Darty…) ou la fragilité de certains groupes (France Loisirs, Virgin, Chapitre…) ? Quelles stratégies développent-elles et quels sont les impacts des aides publiques et du collectif ? À quels enjeux font-elles face aujourd’hui (transmission, fidélisation, différenciation, services…) et avec quels moyens ? Peuvent-elles compter sur un changement de comportement des consommateurs, tel celui qui se manifeste à travers un mouvement comme IndieBound dans les pays anglo-saxons ?

Published: January 2020

Cet article analyse la rencontre entre dispositions sociales des individus se professionnalisant dans le fitness et système managérial d’une marque leader mondiale basé sur des modalités d’apprentissage du métier spécifiques pour la construction d’un fort engagement. Entre rémunération basse et temps de travail élevé, nous souhaitons comprendre comment et pourquoi ces individus s’engagent corps et âme auprès des salles de sport où l’objectif de pratique, loin de celui des activités physiques et sportives ordinaires, concerne une efficacité de corps pour une performance esthétisante. Un « management par corps » est mis en évidence, agissant sur des individus en quête de reconnaissance sociale.
Evidence for impacts on surface-level air quality in the northeastern US from long-distance transport of smoke from North American fires during the Long Island Sound Tropospheric Ozone Study (LISTOS) 2018
Authors: Rogers Haley M. , Ditto Jenna C. , Gentner Drew R. 
Published: January 2020

Abstract. Biomass burning is a large source of uncontrolled air
pollutants, including particulate matter (i.e., PM2.5), black carbon
(BC), volatile organic compounds (VOCs), and carbon monoxide (CO), which
have significant effects on air quality, human health, and climate.
Measurements of PM2.5, BC, and CO made at the Yale Coastal Field
Station in Guilford, CT, and five other sites in the metropolitan New York
City (NYC) area indicate long-distance transport of pollutants from
wildfires and other biomass burning to surface-level sites in the region.
Here, we examine two such events occurring on 16–17 and 27–29 August 2018. In addition to regionally consistent enhancements
in the surface concentrations of gases and particulates associated with
biomass burning, satellite imagery confirms the presence of smoke plumes in
the NYC–Connecticut region during these events. Back-trajectory modeling
indicates that air masses arriving at surface-level sites in coastal
Connecticut on 16–17 August passed over the western coast of
Canada, near multiple large wildfires. In contrast, air parcels arriving on
27–29 August passed over active fires in the southeastern
United States. The results of this study demonstrate that biomass burning
events throughout the US and Canada (at times more than 4000 km away),
which are increasing in frequency, impact surface-level air quality beyond
regional scales, including in NYC and the northeastern US.
Evaluation of Jackson-Pratt Thoracostomy Drains Compared with Traditional Trocar Type and Guidewire-Inserted Thoracostomy Drains
Authors: Sherman Alec , Holt David , Drobatz Kenneth , Mison Michael 
Published: January 2020

ABSTRACT
A restrospective study was performed to evaluate the efficacy of and complications among Jackson-Pratt (JP) drains placed as thoracostomy drains, traditional trocar type (TRO) thoracostomy drains, and guidewire (GW)-inserted thoracostomy drains that were placed in open fashion during thoracotomy. Medical records of 65 canine and feline patients who underwent thoracic surgery were evaluated. Dogs and cats who underwent thoracotomy and had a chest drain placed intraoperatively were included. Data retrieved from medical records included signalment, body weight, diagnosis, surgical approach, surgical procedure, type of thoracostomy drain, postoperative analgesia, duration of thoracostomy drain, and postoperative complications. The incidence of complications and number of medications used in pain protocols were compared among types of thoracostomy drains. JP (n = 31), TRO (n = 25), and GW (n = 9) thoracostomy drains were placed in 65 patients. Ten minor (15.3%) and four major (6.2%) complications occurred. Cases with JP thoracostomy drains were significantly less likely to have complications (2 minor, 1 major) than cases with TRO thoracostomy drains (8 minor, 3 major, P = .009). There were no differences in the number of major complications when comparing all three drains individually (P = .350). JP drains and GW drains can be considered as an alternative to traditional TRO thoracostomy drains.

Published: January 2020

En el presente artículo se aborda la erosión hídrica superficial en la microcuenca del Cauce 31 de Diciembre, Municipio de Managua. El objetivo del estudio fue la determinación de la tasa de erosión hídrica en el área rural de la microcuenca, utilizando la Ecuación Universal Revisada de Pérdida de Suelo (RUSLE), a partir de la erosividad de la lluvia, pendiente del terreno, tipo de suelo, uso de suelo y prácticas de conservación. Se estimó los factores de la ecuación RUSLE en formato raster, y utilizando las herramientas raster del análisis espacial del ArcGIS, se obtuvo el mapa de tasa de erosión hídrica del área rural de la microcuenca en estudio. El estudio sugiere que la tasa de erosión promedio anual varia de 25 a 100 Ton /(ha-año) en la parte media de la subcuenca, representando un nivel erosivo alto, y de 6 a 25 Ton/(ha-año) en la parte alta, representando un nivel erosivo moderado.
Skepticism about Modern Art
Authors: Lee Alan 
Published: January 2020

AbstractFrom the earliest days of abstract and nonobjective art, there have been no widely accepted criteria by which to judge the value or significance of innovation. Only in the visual arts has radical experimentation become the mainstream of creative endeavor, a condition that makes the vocational education of visual artists problematic. The philosopher’s institutional theory stands to describe this condition, but, because it is not a generative theory, it provides no guidance to the aspiring artist or the art educator. The persistence of largely irrelevant “foundation studies” stands to illustrate the unresolved difficulties in tertiary art education. Against this background, I examine the claims of two influential art museum directors, one of whom seeks to justify the processes by which the modern artist rises to fame, while the other attributes progress in modern art to the achievements of individual artists who are exceptional in breaking the rules of the game of modern art as it played at any given time. I argue that the objectivity of these processes of discovery and critical acclaim in contemporary modern art is compromised to an extent that artworld functionaries do not themselves recognize.

Authors: Alesi Marianna , Gómez-López Manuel , Bianco Antonino 
Published: January 2020

Little research has been produced about literacy readiness in Kindergarten children at risk for Developmental Coordination Disorder (DCD), despite this age being one of the most important epoch of motor and cognitive development. In this study we compared pre-literacy skills in Kindergarten children at risk for Developmental Coordination Disorder (DCD) with Typically Developing (TD) children. Participants were 26 Italian children, who had a mean age of 5.1 years, 13 at risk for DCD and 13 TD attending kindergarten schools. Pre-literacy abilities were measured trough tasks derived by the Italian PRCR-2 battery: Semi-circles (A and B), Letter identification and Object Naming Time. Significant differences were found between children at risk for DCD and TD children on tasks of visual memory of printed signs, visual analysis ability, visual discrimination and attention and sequentiality of eye movements. Findings suggest the need to implement pre-school cognitively challenging motor activities programs to enhance manual dexterity, aiming and catching skills as well as static and dynamic balance at early age

ObjectiveTo test the effectiveness of a 32‐week, stepped‐care intervention on disease remission rates in overweight and obese patients with medial tibiofemoral osteoarthritis (OA) compared to controls.MethodsIn this randomized controlled trial, eligible participants were ≥50 years of age with a body mass index of ≥28 kg/m2 and radiographic evidence of medial tibiofemoral OA. Participants were randomized to stepped‐care (n = 87) or control group (n = 84). The stepped‐care group received a 2‐step intervention. The first step consisted of an 18‐week diet and exercise program. The second step consisted of 4 treatment subgroups: 1) diet and exercise maintenance; 2) cognitive–behavioral therapy; 3) unloader knee brace; and 4) muscle strengthening exercises. Allocation into subgroups was based on disease remission state and clinical characteristics. The primary end point was the disease remission rate (yes/no) at 32 weeks, which was reached when participants achieved the Patient Acceptable Symptom State cutoff value for pain and for the patient global assessment of disease activity and/or functional impairment.ResultsDisease remission at 32 weeks was achieved by 18 of 68 (26%) in the control group and 32 of 82 (39%) in the stepped‐care group (difference 12.6% [95% confidence interval –2.3, 27.4], P = 0.10). The stepped‐care group showed an improvement in pain and function between baseline and 20 weeks. While functional improvement was maintained at 32 weeks, pain levels tended to get worse between weeks 20 and 32.ConclusionThe proposed intervention did not promote a significant difference in the rate of disease remission in comparison to the control group for overweight or obese patients with medial tibiofemoral OA.

Published: January 2020

AbstractOriented microstructures are widely found in various biological systems for multiple functions. Such anisotropic structures provide low tortuosity and sufficient surface area, desirable for the design of high‐performance energy storage devices. Despite significant efforts to develop supercapacitors with aligned morphology, challenges remain due to the predefined pore sizes, limited mechanical flexibility, and low mass loading. Herein, a wood‐inspired flexible all‐solid‐state hydrogel supercapacitor is demonstrated by morphologically tuning the aligned hydrogel matrix toward high electrode‐materials loading and high areal capacitance. The highly aligned matrix exhibits broad morphological tunability (47–12 µm), mechanical flexibility (0°–180° bending), and uniform polypyrrole loading up to 7 mm thick matrix. After being assembled into a solid‐state supercapacitor, the areal capacitance reaches 831 mF cm−2 for the 12 µm matrix, which is 259% times of the 47 µm matrix and 403% times of nonaligned matrix. The supercapacitor also exhibits a high energy density of 73.8 µWh cm−2, power density of 4960 µW cm−2, capacitance retention of 86.5% after 1000 cycles, and bending stability of 95% after 5000 cycles. The principle to structurally design the oriented matrices for high electrode material loading opens up the possibility for advanced energy storage applications.

Published: January 2020

AbstractDefects are deliberately introduced into covalent organic frameworks (COFs) via a three‐component condensation strategy. The defective COFs (dCOF‐NH2‐Xs, X = 20, 40, and 60) possess favorable crystallinity and porosity, as well as have active amine functional groups as anchoring sites for further postfunctionalization. By introducing imidazolium functional groups onto the pore walls of COFs via the Schiff‐base reaction, dCOF‐ImBr‐Xs‐ and dCOF‐ImTFSI‐Xs‐based materials are employed as all‐solid‐state electrolytes for lithium‐ion conduction with a wide range of working temperatures (from 303 to 423 K), and the ion conductivity of dCOF‐ImTFSI‐60‐based electrolyte reaches 7.05 × 10−3 S cm−1 at 423 K. As far as it is known, it is the highest value for all polymeric crystalline porous material based all‐solid‐state electrolytes. Furthermore, Li/dCOF‐ImTFSI‐60@Li/LiFePO4 all‐solid Li‐ion battery displays satisfactory battery performance under 353 K. This work not only provides a new methodology to construct COFs with precisely controlled defects for postfunctionalization, but also makes them promising candidate materials as all‐solid‐state electrolytes for lithium‐ion batteries operate at high temperatures.

Published: January 2020

AbstractWith increasing demands for safe, high capacity energy storage to support personal electronics, newer devices such as unmanned aerial vehicles, as well as the commercialization of electric vehicles, current energy storage technologies are facing increased challenges. Although alternative batteries have been intensively investigated, lithium (Li) batteries are still recognized as the preferred energy storage solution for the consumer electronics markets and next generation automobiles. However, the commercialized Li batteries still have disadvantages, such as low capacities, potential safety issues, and unfavorable cycling life. Therefore, the design and development of electromaterials toward high‐energy‐density, long‐life‐span Li batteries with improved safety is a focus for researchers in the field of energy materials. Herein, recent advances in the development of novel organic electrolytes are summarized toward solid‐state Li batteries with higher energy density and improved safety. On the basis of new insights into ionic conduction and design principles of organic‐based solid‐state electrolytes, specific strategies toward developing these electrolytes for Li metal anodes, high‐energy‐density cathode materials (e.g., high voltage materials), as well as the optimization of cathode formulations are outlined. Finally, prospects for next generation solid‐state electrolytes are also proposed.

Published: January 2020

AbstractResearch on artificial photoactivated molecular machines has moved in recent years from a basic scientific endeavor toward a more applicative effort. Nowadays, the prospect of reproducing the operation of natural nanomachines with artificial counterparts is no longer a dream but a concrete possibility. The progress toward the construction of molecular‐machine‐based devices and materials in which light irradiation results in the execution of a task as a result of nanoscale movements is illustrated here. After a brief description of a few basic types of photoactivated molecular machines, significant examples of their exploitation to perform predetermined functions are presented. These include switchable catalysts, nanoactuators that interact with cellular membranes, transporters of small molecular cargos, and active joints capable of mechanically coupling molecular‐scale movements. Investigations aimed at harnessing the collective operation of a multitude of molecular machines organized in arrays to perform tasks at the microscale and macroscale in hard and soft materials are also reviewed. Surfaces, gels, liquid crystals, polymers, and self‐assembled nanostructures are described wherein the nanoscale movement of embedded molecular machines is amplified, allowing the realization of muscle‐like actuators, microfluidic devices, and polymeric materials for light energy transduction and storage.

AbstractThe development of Li–S batteries is largely impeded by the growth of Li dendrites and polysulfide shuttling. To solve these two problems simultaneously, herein the study reports a “single atom array mimic” on ultrathin metal organic framework (MOF) nanosheet‐based bifunctional separator for achieving the highly safe and long life Li–S batteries. In the designed separator, the periodically arranged cobalt atoms coordinated with oxygen atoms (CoO4 moieties) exposed on the surface of ultrathin MOF nanosheets, “single atom array mimic”, can greatly homogenize Li ion flux through the strong Li ion adsorption with O atoms at the interface between anode and separator, leading to stable Li striping/plating. Meantime, at the cathode side, the Co single atom array mimic serves as “traps” to suppress polysulfide shuttling by Lewis acid‐base interaction. As a result, the Li–S coin cells with the bifunctional separator exhibit a long cycle life with an ultralow capacity decay of 0.07% per cycle over 600 cycles. Even with a high sulfur loading of 7.8 mg cm−2, an areal capacity of 5.0 mAh cm−2 can be remained after 200 cycles. Moreover, the assembled Li–S pouch cell displays stable cycling performance under various bending angles, demonstrating the potential for practical applications.

Published: January 2020

AbstractWe synthesized a bidentate bispyridylhydrazone functionalized copillar[5]arene (BACP5A), which can self‐assemble through strong intermolecular hydrogen bonds. BACP5A self‐assembled into size‐controllable vesicles, with the synergistic interactions of intermolecular hydrogen bonding and internal amphiphilicity, which are responsive to pH, temperature and solvent. BACP5A was used to form a bidentate metal‐ligand coordinated complex with Zinc trifluoromethanesulfonate in which a new rectangular cavity containing hexacoordinated zinc ions occurred between two adjacent BACP5A. This type of coordinated complex may be employed for the development of new macrocyclic‐based artificial enzymes.

Authors: Loenarz Christoph 
Published: January 2020

AbstractDer diesjährige Nobelpreis für Physiologie oder Medizin wird drei Forschern verliehen, die ihre Karriere der Beantwortung einer grundlegenden wissenschaftlichen Fragestellung gewidmet haben: Wie wird in tierischen Zellen eine unzureichende Sauerstoffversorgung signalisiert, und mittels welcher Mechanismen passen sich Zellen auf derart geänderte Bedingungen an? Mit der Identifizierung des Hypoxie‐induzierten Faktors (HIF) und der Aufklärung assoziierter Signalwege bieten sich neue Forschungsansätze zur Therapie von Krebs, Anämie, und verschiedenen kardiovaskulären Erkrankungen. Der ausgeklügelte molekulare Mechanismus des zellulären Sauerstoffsensors führte zu breitem Interesse an der Familie der Eisen(II)/2‐Oxoglutarat‐abhängigen Enzyme – zuvor primär im Kontext komplexer Naturstoffbiosynthese bekannt. Neben substantiellem Fortschritt im Verständnis der Hydroxylierung biologischer Makromoleküle ermöglicht das Werk der diesjährigen Preisträger die Beschreitung neuer Wege für molekulare Wissenschaftler auf vielfältigen Gebieten wie C‐H‐Aktivierung, PROTAC‐Technologie, medizinische Chemie und Epigenetik.
