Quand les familles initient les enfants au monde connecté. Enquête sur l’acquisition et l’appropriation de la tablette numérique
Authors: Lachance Jocelyn , Ramos Antón Rubén 
Published: March 2020

Si l’usage des tablettes par les enfants est l’objet d’enquêtes quantitatives, nous possédons peu d’informations à ce jour concernant l’appropriation par les enfants des tablettes dans le contexte familial. Cet article restitue les principaux résultats d’une enquête qualitative menée auprès d’enfants âgés entre 8 et 11 ans d’origine française et espagnole au sujet de leurs usages de la tablette numérique à la maison (N=22). Il apparaît ici que la tablette participe à l’initiation des enfants au monde connecté, en banalisant l’ubiquité médiatique lors de conversations avec des parents éloignés et des amis avec qui l’on joue à distance. Si la tablette offre la possibilité pour ces enfants de manifester leur autonomie, la place qu’elle occupe dans leur vie questionne notamment le rôle de la famille comme prescripteur de la connexion.
Archéologie et paysages dans la plaine rhénane septentrionale
Authors: Lasserre Marina , Logel Thierry 
Published: March 2020

La zone dite du Ried-nord est une portion de la plaine alluviale du Rhin qui s’étend entre la forêt de Haguenau à l’ouest et la Forêt-Noire à l’est. Le paysage actuel est encore marqué par la présence de vastes bras fossiles du fleuve qui parcourent l’ensemble de l’espace alluvial, soit une quinzaine de kilomètres de largeur en moyenne. Plusieurs recoupements de ces puissants bras soulignent l’importance des mouvements latéraux du fleuve qui ont balayé cet espace avant l’endiguement du Rhin au courant du XIXe siècle.Comment les Hommes des sociétés passées se sont-ils accommodés de ce paysage particulier ? à partir de plusieurs sources croisées, une histoire sur plusieurs millénaires des relations entre les Hommes et le fleuve se dessine. L’évolution de l’occupation du sol du Ried-nord est affectée par la nature particulière des déplacements latéraux du Rhin et des risques de crues violentes. Ces deux éléments vont être déterminants pour comprendre le mode de colonisation de cet espace rhénan en plus de sa microtopographie constituée de quelques secteurs légèrement surélevés qui constitueront les espaces privilégiés à l’installation des premières occupations humaines, saisonnières et pérennes.

L’accessibilité des chroniques urbaines, les usages potentiels qui pouvaient en être faits et les types d’utilisateurs ou utilisatrices de ces textes variaient d’une ville à l’autre. Les chroniques officielles, normalement commandées par le Conseil de ville, étaient souvent conservées dans ses archives. L’accès était alors généralement restreint, et le public ne pouvait que de temps à autre jeter un œil sur le codex contenant l’histoire de la cité. Dans certaines villes, des textes historiques étaient lus publiquement lors d’occasions particulières, dans d’autres, des copies d’apparat étaient montrées aux visiteurs de marque. Certains manuscrits étaient cachés et servaient de réservoir (symbolique) de savoir secret pour les dirigeants, alors que d’autres tombaient tout simplement dans l’oubli. La gloire d’une œuvre ne se reflétait pas forcément dans l’usage réel qui était fait d’un manuscrit concret, comme cela semble être le cas pour la chronique de Jakob Twinger von Königshofen, rédigée vers la fin du XIVe siècle. Il existait au XVe siècle un grand nombre de copies de cette chronique à Strasbourg, mais les manuscrits autographes de Twinger, conservés au Frauenhaus, le bâtiment administratif de l’Œuvre Notre-Dame, la fabrique de la cathédrale, n’étaient apparemment pas utilisés, malgré la renommée dont jouissait la chronique parmi les Strasbourgeois s’intéressant à l’histoire. L’article s’interroge sur le contraste entre la connaissance de l’œuvre abstraite et la méconnaissance du manuscrit concret dans la conscience collective. (trad. O.R.)

Abstract
IκBζ (encoded by the Nfkbiz) is a member of the nuclear IκB family, which is involved in the expression of secondary response genes based on signals from TLR or IL-1R. ST2L, an IL-33R, is a member of the IL-1R family and abundantly expressed in tissue-resident immune cells, such as mast cells and innate lymphoid cells; however, its downstream signaling pathway remains unelucidated. In this study, we examined the role of IκBζ in ST2L-mediated cytokine and chemokine production in mast cells. Murine bone marrow cells were differentiated ex vivo into bone marrow–derived mast cells (BMMCs). The treatment of BMMCs with IL-33 transiently induced robust IκBζ expression. Of the 40 cytokines and chemokines examined using a cytokine and chemokine array, the concentrations of IL-6, IL-13, CCL2, CCL3, and TNF-α in the supernatant were augmented by IL-33. The deletion of IκBζ in BMMCs resulted in a significant reduction of the production of these mediators and the expression of their mRNA. NF-κB p50 but not p65 translocated to the nucleus by IL-33 and was not affected by the deletion of IκBζ. However, induction of IκBζ and the resultant cytokine and chemokine productions were significantly inhibited by pretreatment with an NF-κB inhibitor. The deletion of IκBζ did not affect the phosphorylation of ERK, p38 MAPK, or JNK by IL-33, and the treatment with inhibitors of these mitogen-activated kinases failed to abolish the expression of Nfkbiz. Our findings suggest that IκBζ augments IL-33–dependent cytokine and chemokine production in BMMCs through the action of NF-κB.

Abstract. Diurnal variation of surface PM2.5 concentration (diurnal PM2.5)
could dramatically affect aerosol radiative and health impacts and can also
well reflect the physical and chemical mechanisms of air pollution formation
and evolution. So far, diurnal PM2.5 and its modeling capability over
East China have not been investigated and therefore are examined in this
study. Based on the observations, the normalized diurnal amplitude of
surface PM2.5 concentrations averaged over East China is weakest (∼1.2) in winter and reaches ∼1.5 in other seasons. The diurnal PM2.5 shows the peak concentration during the night in spring and fall and during the daytime in summer. The simulated diurnal PM2.5 with WRF-Chem and its contributions from multiple physical and chemical processes are examined in the four seasons. The simulated diurnal PM2.5 with WRF-Chem is primarily controlled by planetary boundary layer (PBL) mixing and emission variations and is significantly overestimated against the observation during the night. This modeling bias is likely primarily due to the inefficient PBL mixing of primary PM2.5 during the night. The simulated diurnal PM2.5 is sensitive to the PBL schemes and vertical-layer configurations with WRF-Chem. Besides the PBL height, the PBL mixing coefficient is also found to be the critical factor determining the PBL mixing of pollutants in WRF-Chem. With reasonable PBL height, the increase in the lower limit of the PBL mixing coefficient during the night can significantly reduce the modeling biases in diurnal PM2.5 and also the mean concentrations, particularly in the major cities of East China. It can also reduce the modeling sensitivity to the PBL vertical-layer configurations. The diurnal variation and injection height of anthropogenic emissions also play roles in simulating diurnal PM2.5, but the impact is relatively smaller than that from the PBL mixing. This study underscores that more efforts are needed to improve the boundary mixing process of pollutants in models with observations of PBL structure and mixing fluxes in addition to PBL height, in order to simulate reasonably the diurnal PM2.5 over East China. The diurnal variation and injection height of anthropogenic emissions must also be
included to simulate the diurnal PM2.5 over East China.

Context.—
The updated American Society of Clinical Oncology/College of American Pathologists guideline for human epidermal growth factor receptor 2 (HER2) testing in breast cancer requires pathologists to re-evaluate HER2 status.

Objective.—
To define HER2 status of breast cancer using immunohistochemistry and fluorescence in situ hybridization.

Design.—
Diagnostic reports of invasive breast cancers made between 2014 and 2018 with HER2 immunohistochemistry and fluorescence in situ hybridization results were retrieved. HER2 status was re-defined using the updated recommendations.

Results.—
Of 2514 tumors, 89.7% (2254 of 2514) suggested for fluorescence in situ hybridization assay were HER2 immunohistochemistry 2+. Approximately 8.9% (225 of 2514) and 1.4% (35 of 2514) of tumors were of immunohistochemistry 0/1+ and 3+, respectively. Based on the average HER2 copy number and HER2:CEP17 ratio, tumors were assigned into 5 groups, including 13.1% (330 of 2514) group 1 tumors, 2.1% (52 of 2514) group 2 tumors, 1.1% (27 of 2514) group 3 tumors, 7.0% (175 of 2514) group 4 tumors, and 76.8% (1930 of 2514) group 5 tumors. In combination with immunohistochemistry, all tumors in group 2 and group 4 changed HER2 status, from positive and equivocal into negative, respectively, while group 3 tumors remained positive. Comparative analyses of clinicopathologic features of tumors in different groups revealed that group 2 and 4 tumors displayed worse clinicopathologic features than those of group 5, while group 3 tumors shared similar clinicopathologic features to those of group 1.

Conclusions.—
Following the updated guideline, HER2 status is clearly designated. Significant differences regarding clinical features were observed between tumors in different groups but they share the same HER2 status, suggesting further validation of the accuracy of this diagnostic approach is warranted.

Published: March 2020

Abstract

Context
As a proposed alternative to the traditional recertification examination, CATALYST is a longitudinal formative assessment platform created on cognitive learning principles. CATALYST was designed by the National Board of Osteopathic Medical Examiners to encourage more complex and durable practice-relevant learning and demonstration of ongoing competencies.

Objective
To investigate the value of the CATALYST platform using board diplomates’ subjective feedback and comparison of performance on CATALYST questions with performance on board examinations.

Methods
Diplomates from 3 osteopathic specialty boards (the American Osteopathic Board of Internal Medicine, the American Osteopathic Board of Pediatrics, and the American Osteopathic Board of Obstetricians and Gynecologists) participated in this pilot study. Over the course of 16 weeks, participants were provided 2 questions per week via the CATALYST platform. An evaluation survey was emailed at the end of the study period to collect participants’ feedback. Survey results and correlations of CATALYST performance with past or upcoming board examination scores were analyzed.

Results
A total of 196 diplomates completed the surveys, with 95% reporting that participation in the platform would help them stay current in their specialties and 91% reporting that participation would help them provide better care to their patients. For the AOBIM, a significant correlation was found between the number of CATALYST questions answered correctly and performance on the board examination (r=0.51, P<.001). The correlations found for the AOBP and AOBOG were not significant (r=0.197, P=.296, and r=0.370, P=.075, respectively).

Conclusion
The CATALYST platform could offer valuable contributions to the board recertification process and to patient safety. Further investigations are being conducted on a new user-friendly platform.

Published: December 2024

AbstractIntermetallics, which encompass a wide range of compounds, often exhibit similar or closely related crystal structures, resulting in various intermetallic systems with structurally derivative phases. This study examines the hypothesis that deformation behavior can be transferred from fundamental building blocks to structurally related phases using the binary samarium‐cobalt system. SmCo2 and SmCo5 are investigated as fundamental building blocks and compared them to the structurally related SmCo3 and Sm2Co17 phases. Nanoindentation and micropillar compression tests are performed to characterize the primary slip systems, complemented by generalized stacking fault energy (GSFE) calculations via atomic‐scale modeling. The results show that while elastic properties of the structurally complex phases follow a rule of mixtures, their plastic deformation mechanisms are more intricate, influenced by the stacking and bonding nature within the crystal's building blocks. These findings underscore the importance of local bonding environments in predicting the mechanical behavior of structurally related intermetallics, providing crucial insights for the development of high‐performance intermetallic materials.
Chemomechanical Self‐Oscillatory Microgel Motility in Stratified Chemical Media

Published: December 2024

AbstractThe design of chemomechanical self‐oscillators, which execute oscillations in the presence of constant stimuli lacking periodicity, is a step toward the development of autonomous and interactive soft robotic systems. This work presents a simple design of prolonged chemomechanical oscillatory movement in a microgel system capable of buoyant motility within stratified chemical media containing spatially localized sinking and floating stimuli. Three design elements are developed: a stimuli‐responsive membranized calcium alginate microgel, a Percoll density gradient for providing stratified antagonistic chemical media, and transduction of microgel particle size actuation into buoyant motility via membrane‐mediated displacement of the Percoll media. The presence of citrate or calcium ions in different layers of the Percoll media gives rise to swelling (buoyancy) or contraction (geotaxis), respectively, which in turn mediate the shuttling of the microgels between the layers to produce prolonged or damped chemomechanical oscillatory trajectories. The concentration‐dependence of the oscillatory behavior in the stratified media, the density gap between the Percoll layers, and the kinetic asymmetry of microgel swelling and deswelling are studied. The illustrated modular design allows for the development of chemomechanical self‐oscillators responsive to light, pH, or temperature, which will find applications in interactive soft robotics, autonomous microbots, and intelligent materials.
High‐Performance Broad‐Spectrum Photodetector by Suppressing Stray Electrons by Adopting a Hybrid CQD/Organic Architecture

ABSTRACTBroad‐spectrum photodetectors (PDs) are essential for various health monitoring, night vision, and telecommunications applications, but their detectivity in a wide absorbance region is limited by undesirable electronic response properties. Colloidal quantum dots (CQDs) are a promising system for broad‐spectrum detection, whereas their practical potential is hindered by suboptimal dark current characteristics. To overcome these challenges, we propose a layered architecture comprising CQDs and a bulk heterojunction (BHJ) organic film as a hole transport layer. The integration of PbS CQDs offers multiple benefits, including bandgap tuning for minimizing thermal carriers, surface passivation to reduce recombination rates, and the formation of high‐quality interfaces with organic layers, which collectively contribute to suppressing dark current leakage and thermal excitations by suppressing stray electrons. By integrating ITIC into the BHJ film, the device detectability is significantly enhanced, reaching 1013 Jones in the 400–1000 nm spectral range. This improvement is attributed to the higher lowest unoccupied molecular orbital (LUMO) of ITIC molecules, which effectively hinders electron injection. Additionally, J‐aggregation‐induced molecular stacking and optimized phase separation of BHJ films contribute to the enhanced performance. The integration of diverse materials offers greater flexibility in device design and functionality, enabling the development of more advanced and sophisticated optoelectronic devices. Furthermore, this approach could significantly enhance the theoretical and practical understanding of optoelectronic device engineering, leading to the development of more advanced optoelectronic devices.
Iron(III) Bis(Phenol) Amine Complex Supported on Functionalized Graphene Oxide Nanosheets as an Efficient and Recoverable Catalyst for Room Temperature Epoxidation of Alkenes

Published: December 2024

ABSTRACTIron(III) bis(phenol) amine complex immobilized on the surface of functionalized graphene oxide nanosheets (FeLGDC‐AP/GO) has introduced as a highly active and recoverable catalyst for the epoxidation of alkenes. Optimizing different parameters in the oxidation of styrene as a model substrate revealed that 100% conversion and selectivity were obtained toward styrene oxide in the presence of H2O2 (28 wt%) as oxidant and water/acetone (3:1) as a solvent system in a bicarbonate buffer system. Furthermore, the catalyst displayed 54%–100% conversion and 90%–100% selectivity for the epoxidation of various aromatic and aliphatic alkenes under optimized reaction conditions at room temperature. The recycling experiment showed that FeLGDC‐AP/GO could be easily recovered by simple filtration and recycled six times without loss of the activity and selectivity. The high catalytic activity and selectivity of the developed catalyst could be attributed to the well‐designed coordination sphere around the iron core as well as the presence of GO support, which facilitates the electron transfer process beside the catalyst recovery.

Authors: Mousavi‐Mashhadi Seyed Ali , Shiri Ali 
Published: December 2024

ABSTRACTA new copper acetylacetonate immobilized on halloysite nanotube (HNT) was synthesized. For this purpose, (3‐aminopropyl)trimethoxysilane (AMPTSi) was covalently bonded to the surface of halloysite nanotubes, and then copper acetylacetonate was immobilized onto the modified support. The chemical and physical structure of Cu(acac)2/AMPTSi/HNTs were characterized via various analyses such as TEM, SEM, EDS, FTIR, XRD, TGA, and N2 adsorption–desorption. The efficiency of this catalyst was studied in a one‐pot three‐component reaction of benzaldehydes, dimedone, and malononitrile/ethyl cyanoacetate for the synthesis of 4H‐chromenes. For all substrates, good to excellent yields of the corresponding 4H‐chromenes were obtained.
Thirty years of persuasion knowledge research: From demonstrating effects to building theory to increasing applicability
Authors: Isaac Mathew S. , Calder Bobby J. 
Published: December 2024

AbstractPersuasion knowledge, which encapsulates consumers' literacy of common marketing tactics and their assumptions about what marketers hope to accomplish by using these tactics, has inspired substantial research in consumer psychology, advertising, and many other fields. The original article introducing the persuasion knowledge model (PKM; Friestad & Wright, 1994) has grown in importance over the past 30 years. A major strength of extant persuasion knowledge research is that it has investigated effects that have applicability to the traditional media advertising context. We point out the need, however, for further theory development aimed at explaining the persuasion knowledge effects that have been observed, and we discuss the value of considering dual‐processing theories in this regard. We further contend that persuasion knowledge research should be broadened beyond the context of traditional advertising to encompass content marketing. Finally, we consider how the interplay of theory and effects can allow greater applicability in behavioral research.

AbstractThe behavior of biomass pyrolysis can be predicted by analyzing its characteristics. This study aimed to model the release of volatiles across various temperatures, biomass properties, and heating rates. Palm kernel shells were pyrolyzed at 433–773 K with a heating rate of 5 K·min−1 using volatile‐state kinetic modeling. The process began by calculating the biomass type number (NCT), which was used to determine volatile enhancement (VE), volatile release yield (YVY), product yield (Yi), and product mass fraction (yi). The kinetic parameters, including the activation energy for product formation (Eai), were derived through a fitting process.The results indicate a YVY of 70.77% within the devolatilization zone, corresponding to the degradation of cellulose and hemicellulose. The YVY increased with higher temperatures, lower NCT, and higher heating rates. The activation energy ranged from 155–185 kJ·mol⁻¹ for biocrude oil (BCO) and 149–186 kJ·mol⁻¹ for gas. The kinetic parameters from the volatile‐state kinetic model demonstrated errors below 0.2% in comparison with the experimental data, confirming the model's accuracy and reliability.
