Percepción de los estudiantes de Maestro de Educación Primaria sobre su competencia digital, urgencias formativas detectadas.
Authors: Fombona Javier , Pascual Maria Angeles 
Published: November 2020

El dinamismo del fenómeno de las nuevas tecnologías aplicadas a la educación obliga a la comunidad académica a revisar de forma sistemática el nivel de dominio de los estudiantes sobre las competencias relacionadas. Este trabajo forma parte de una amplia investigación que analiza la formación sobre nuevas tecnologías que posee el alumnado del Grado de Maestro de Educación Primaria en tres universidades españolas (Granada, Jaén y Oviedo). El estudio se centra en una muestra de 559 estudiantes y pone en relieve las fortalezas y debilidades que tienen actualmente en materia TIC, haciendo énfasis en aquellos aspectos que deben ser objeto de especial atención didáctica. Los resultados muestran nuevos retos para el docente, ya sean aspectos técnicos, legislativos, o cuestiones relacionadas con la seguridad, tales como el acoso o la ansiedad derivada. Este incremento de contenidos no debe ser óbice para continuar abordando temas TIC tradicionales y de elevado impacto, dado que los datos indican que esos aspectos se vuelven nuevamente lagunas del conocimiento.
The new technologies applied to education are a dynamic phenomenon, and this forces the academic community to review the level of students’ knowledge over their real competences. This work is part of an extensive research that analyzes the training on the students’ ICT of the Primary School Degree Teacher Training, on three Spanish universities (Granada, Jaén and Oviedo). The study focuses on a sample of 559 students and highlights the strengths and weaknesses about their ICT skills, emphasizing those aspects that should be specially studied. The results show new challenges for the teacher, technically, legislatively, or about security-related issues, such as cyberbullying or anxiety. This increase in subjects should not be an obstacle to continue addressing traditional ICT issues, since our results show these aspects again become gaps in the students’ knowledge.
L’entreprise comme lieu d’apprentissage et de changement : monographie de la première certification iso 9001 en Algérie
Authors: Arab Abdellah , Lambert Gilles 
Published: November 2020

Les études mettant en relation la démarche RSE et les théories de la gouvernance de l’entreprise (Charreaux, 2006; Cespa et Cestone, 2007) ont permis d’expliquer dans le contexte algérien l’élargissement du pouvoir des managers et la privatisation des entreprises (Gana-Oueslati et Labaronne, 2011). Malgré la pertinence de ces recherches, nous montrons que l’entreprise n’est pas réductible à des noeuds de contrats. Elle est aussi un lieu de changements et d’apprentissages (Argyris et Schön, 2002; March, 1991). Dans le contexte d’une entreprise publique algérienne, nous proposons d’apprécier les apprentissages provenant de la certification à la norme ISO 9001.
L’influence des facteurs stratégiques et organisationnels sur les relations entre contrôle de gestion environnemental et apprentissage organisationnel : le cas d’une éco-PME missionnaire
Authors: Renaud Angèle , Berland Nicolas 
Published: November 2020

Cet article étudie les relations entre contrôle de gestion environnemental (CGE) et apprentissage organisationnel (AO) en inscrivant le modèle de Simons (1995) dans une perspective contingente. Par des facteurs stratégiques et organisationnels, ce modèle enrichi explique les liens entre les modes de contrôle (diagnostique et interactif) de Simons et les niveaux d’apprentissage (en simple et double boucle) d’Argyris et Schön (1978). S’appuyant sur le « cas révélateur » d’une éco-PME missionnaire, l’étude montre l’influence de trois facteurs (valeurs fortes, stratégie proactive, cycle de vie des activités) sur les quatre configurations relationnelles CGE-AO et ouvre de nouvelles perspectives aux travaux de Simons.
Faire l’histoire de la médicalisation en Chine du Sud au début du XXe siècle : l’expérience des sources
Authors: Girouard Kim 
Published: November 2020

À partir du cas d’étude de la province méridionale chinoise du Guangdong, cet article interroge la tendance marquée de l’historiographie à aborder le phénomène de la médicalisation en Chine au début du XXe siècle à partir des cas de Beijing et Shanghai. En révélant les limites et les biais que présentent les archives de la Rockefeller Foundation, incontournables des travaux de recherches sur le sujet, il soulève l’idée selon laquelle ces sources auraient pu contribuer à infléchir la démarche des chercheurs et à entretenir un certain désintérêt pour les initiatives médicalisatrices dans les régions chinoises excentrées comme le Guangdong.
Rencontre et représentations des femmes chinoises dans les récits des voyageurs européens aux XVIIe et XVIIIe siècles
Authors: Gosselin Frédérick 
Published: November 2020

Cet article examine la représentation des femmes chinoises dans les récits d’ambassadeurs européens des XVIIe et XVIIIe siècles. S’appuyant sur l’ambassade hollandaise de 1655 mise en récit par Jehan de Nieuhoff et sur l’ambassade anglaise dirigée par Macartney de 1792 à 1794, mise en récit par George Leonard Staunton, ce texte examine d’une part les représentations de la beauté et la construction des genres et soutient, d’autre part que les perceptions à l’égard de la femme sont les résultats du contexte de représentation globale de la Chine à cette époque, soit le passage de la sinophilie à la sinophobie.
miR-224, miR-147b and miR-31 associated with lymph node metastasis and prognosis for lung adenocarcinoma by regulating PRPF4B, WDR82 or NR3C2

Published: November 2020

Background
The present study is to screen lymph node metastasis-related microRNAs (miRNAs) in lung adenocarcinoma (LUAD) and uncover their underlying mechanisms.

Methods
The miRNA microarray dataset was collected from the Gene Expression Omnibus database under accession number GSE64859. The differentially expressed miRNAs (DEMs) were identified using a t-test. Target genes of DEMs were predicted through the miRWalk2.0 database. The function of these target genes was annotated with the clusterProfiler and the Database for Annotation, Visualization and Integrated Discovery (DAVID) tools. Protein-protein interaction network was established using the STRING database to extract hub target genes. The expressions and associations with survival and lymph node metastasis of miRNAs and target genes were validated by analysis of The Cancer Genome Atlas (TCGA) dataset.

Results
Eight DEMs were identified between lymph node metastasis and non-metastasis samples of GSE64859 dataset. miRNA-target gene pairs were predicted between six DEMs and 251 target genes (i.e. hsa-miR-224-PRPF4B, hsa-miR-147b-WDR82 and hsa-miR-31-NR3C2). The clusterProfiler analysis showed WDR82 was involved in the mRNA surveillance pathway, while the GO enrichment analysis using the DAVID database indicated PRPF4B participated in the protein phosphorylation and NR3C2 was related with the transcription, DNA-templated. WDR82 and PRPF4B may be hub genes because they could interact with others. Two DEMs (miR-31-5p and miR-31-3p) and 45 target genes (including PRPF4B and NR3C2) were significantly associated with overall survival. The expressions of miR-224 and miR-147b were validated to be upregulated, while WDR82, PRPF4B and NR3C2 were downregulated in lymph node metastasis samples of TCGA datasets compared with non-metastasis samples. Also, there were significantly negative expression correlations between miR-147b and WDR82, between miR-224 and PRPF4B, as well as between miR-31 and NR3C2 in LUAD samples.

Conclusions
The present study identified several crucial miRNA-mRNA interaction pairs, which may provide novel explanations for the lymph node metastasis and poor prognosis for LUAD patients.
Improving Dielectric Constant of Polymers through Liquid Electrolyte Inclusion

Published: November 2020

AbstractDifferent from the traditional ways for enhancing the dielectric properties of polymers by compositing with rigid electronic conductors, here an alternative strategy is reported via introducing ionically conductive liquid electrolytes as functional fillers. Dielectric constant has significantly improved (up to 600%) by liquid electrolyte inclusions in an elastomer matrix. Moreover, by taking advantage of the inherent transparency of liquid electrolyte fillers, high transparency, good stretchability, and high dielectric constant are achieved simultaneously. Using the composite elastomer, the fabrication of highly sensitive strain sensor is demonstrated with 5–6 times higher sensitivity than the pristine elastomer, and flexible electroluminescent device with greatly lowed driving voltage. The strategy provides new opportunities for novel electroactive polymers, including flexible touchscreen panels and displays, biomimetic soft machines, and smart optics.

Published: November 2020

AbstractCurrently, the exploration of energy conversion/storage devices for high‐temperature operation with desired stability is still a grand challenge. In the present work, the high‐temperature supercapacitors (SCs) based on SiC nanowires as the electrode materials are reported, which are synthesized via pyrolysis of polymeric precursors followed by etching for creating more active sites with enhanced surface area. In 2.0 m KCl aqueous electrolyte, the as‐fabricated electrode based on etched SiC nanowires delivers a specific capacitance of 23.6 mF cm–2 (29.5 F g–1) at a current density of 0.2 mA cm–2 (0.25 A g–1), which is ≈3.3 times to that of the counterpart without etching (7.19 mF cm–2). The as‐constructed ionic‐liquid‐based SCs can endure the operation temperatures up to 150 °C with a capacitance retention of 80% for 10 000 cycles, which drops only ≈6% in comparison to that at 0 °C. Even under progressive variation in temperatures ranged between 0 and 150 °C, the capacitance retentions keep higher than 76% for 12 000 cycles, representing their promising to be serviced as robust SCs against high‐temperature harsh conditions for energy storage.

Authors: Li Xipeng , Zhao Yu , Zhang Tao , Xing Da 
Published: November 2020

AbstractMitochondria‐targeted photodynamic therapy (Mt‐PDT), which enables the photogenerated cytotoxic oxygen species with fatal oxidative damage to block mitochondrial functions, has been considered as a promising method to enhance the anticancer effectiveness. Aiming at the challenges of PDT, in the past few decades, numerous mitochondria‐targeting molecular agents have been developed to boost the PDT efficacy via directly destroying the mitochondria or activating mitochondria‐mediated cell death pathways. Herein, a review for recent advances of Mt‐PDT is highlighted including: mitochondrial targeting design principles and strategies, therapeutic performance of mitochondria‐targeted agents‐mediated PDT as well as the agent‐free Mt‐PDT. In addition, it puts together the achievements of the combinatory mitochondria‐anchoring PDT and other anticancer strategies, demonstrating the advantages provided by Mt‐PDT. The existing challenges are discussed and future settlements for the development of mitochondria‐specific agents are also forecasted.

Published: November 2020

AbstractControlling the spatial organization of π‐conjugated molecules in soft systems is of importance for the design of new materials with application relevant optimized properties. Here, soft self‐assembly of functional multi‐chained π‐conjugated 5,5′‐diphenyl‐2,2′‐bithiophenes is investigated. Focus is on molecules with a 3,5‐disubstitution pattern at one end and no or only a single chain at the other end. By elongation of the single terminal chain, a transition from lamellar phases to helical networks is observed. With lowering the temperature, the lamellar phase types change from smectic via hexatic to crystalline. In some cases, different kinds of orders are combined in a single uniform lamellar structure. Moreover, a transition from uniform (synclinic) to alternating (anticlinic) tilt in adjacent layers is observed with decreasing chain length or rising temperature, due to a change of the molecular conformation from tuning fork like to Y‐shaped. For compounds terminated with a long chain, helical self‐assembly of the π‐conjugated rods in networks takes place, leading either to a racemic (, gyroid) or a spontaneous mirror symmetry broken (I23) bicontinuous cubic phase and a chiral isotropic liquid phase (Iso1[*]) as well. This work establishes rules for controlling the self‐assembly of functional π‐conjugated rods in soft matter and fluids.

AbstractPlasmonic metafilms have been widely utilized to generate vivid colors, but making them both active and flexible simultaneously remains a great challenge. Here flexible active plasmonic metafilms constructed by printing electrochromic nanoparticles onto ultrathin metal films (<15 nm) are presented, offering low‐power electricallydriven color switching. In conjunction with commercially available printing techniques, such flexible devices can be patterned using lithography‐free approaches, opening up potential for fullyprinted electrochromic devices. Directional optical effects and dynamics show perceived upward and downward colorations can differ, arising from the dissimilar plasmonic mode excitation between nanoparticles and ultrathin metal films.
Perovskite Oxynitride Solid Solutions of LaTaON2‐CaTaO2N with Greatly Enhanced Photogenerated Charge Separation for Solar‐Driven Overall Water Splitting

Published: November 2020

AbstractThe search for solar‐driven photocatalysts for overall water splitting has been actively pursued. Although metal oxynitrides with metal d0/d10‐closed shell configuration are very promising candidates in terms of their visible light absorption, they usually suffer from serious photo‐generated charge recombination and thus, little photoactivity. Here, by forming their solid solutions of LaTaON2and CaTaO2N, which are traditionally considered to be inorganic yellow‐red pigments but have poor photocatalytic activity, a class of promising solar‐driven photocatalysts La1‐xCaxTaO1+yN2‐y(0 ≤x,y≤ 1) are explored. In particular, the optimal photocatalyst withx= 0.9 has the ability of realizing overall water splitting with stoichiometric H2/O2ratio under the illumination of both AM1.5 simulated solar light and visible light. The modulated key parameters including band structure, Ta bonding environment, defects concentration, and band edge alignments revealed in La0.1Ca0.9TaO1+yN2‐yhave substantially promoted the separation of photogenerated charge carriers with sufficient energetics for water oxidation and reduction reactions. The results obtained in this study provide an important candidate for designing efficient solar‐driven photocatalysts for overall water splitting.
Predictors of long‐term opioid use and opioid use disorder among construction workers: Analysis of claims data
Authors: Dale Ann Marie , Buckner‐Petty Skye , Evanoff Bradley A. , Gage Brian F. 
Published: November 2020

AbstractBackgroundConstruction workers have high rates of work‐related musculoskeletal disorders, which lead to frequent opioid use and opioid use disorder (OUD). This paper quantified the incidence of opioid use and OUD among construction workers with and without musculoskeletal disorders.MethodsWe conducted a retrospective study using union health claims from January 2015 to June 2018 from 19,909 construction workers. Claims for diagnoses of chronic musculoskeletal disorders, acute musculoskeletal injuries, musculoskeletal surgery, and other conditions were linked to new opioid prescriptions. We examined the effects of high doses (≥50 morphine mg equivalents per day), large supply (more than 7 days per fill), long‐term opioid use (60 or more days supplied within a calendar quarter), and musculoskeletal disorders, on the odds of a future OUD.ResultsThere were high rates (42.8% per year) of chronic musculoskeletal disorders among workers, of whom 24.1% received new opioid prescriptions and 6.3% received long‐term opioid prescriptions per year. Workers receiving opioids for chronic musculoskeletal disorders had the highest odds of future OUD: 4.71 (95% confidence interval 3.09–7.37); workers prescribed long‐term opioids in any calendar quarter had a nearly 10‐fold odds of developing an OUD.ConclusionsAmong construction workers, opioids initiated for musculoskeletal pain were strongly associated with incident long‐term opioid use and OUD. Musculoskeletal pain from physically demanding work is likely one driver of the opioid epidemic in occupations like construction. Prevention of work injuries and alternative pain management are needed for workers at risk for musculoskeletal injuries.
Recent Advances of Photoresponsive Supramolecular Switches

Published: November 2020

AbstractPhotoresponsive supramolecular switches refer to these host‐guest systems that can be reversibly shifted between different states by light stimuli. Such photoswitchable systems feature the presence of non‐covalent bonding interactions with light‐responsive moieties (e. g., azobenzene and stilbene, spiropyran and diarylethene, coumarin and anthracene), and have been applied in a variety of fields, such as drug delivery, tissue engineering and smart materials with the advantage of being able to operate cleanly and remotely in a spatiotemporally‐controlled fashion. Alternating UV/visible light irradiation can reversibly regulate the binding affinity or assembly/disassembly of the systems. This minireview summarizes recent progress (2016 and after) on the development of photoswitchable host‐guest systems, including the structural designs of these molecular switches and their applications in solution and solid states. Better knowledge of them is essential for the understanding of host‐guest phenomena, molecular machines, and also for the preparation of novel applied materials in the future.

Published: November 2020

AbstractMolecular doping plays an important role in the modification of carrier density of organic semiconductors thus enhancing their optoelectronic performance. However, efficient n‐doping remains challenging, especially owing to the lack of strongly reducing and air‐stable n‐dopants. Herein, an N‐heterocyclic carbene (NHC) precursor, DMImC, is developed as a thermally activated n‐dopant with the excellent stability in air. Its thermolysis in situ regenerates free NHC and subsequently dopes typical organic semiconductors. In sequentially doped FBDPPV films, DMImC does not disturb the π–π packing of the polymer and achieves good miscibility with the polymer. As a result, a high electrical conductivity of up to 8.4 S cm−1is obtained. Additionally, the thermally activated doping and the excellent air stability permit DMImC to be noninteractively co‐processed with polymers in air. Our results reveal that DMImC can be served as an efficient n‐dopant suitable for various organic semiconductors.
