La culture littéraire des élèves allophones en classes ordinaires
Authors: Biales Anne-Laure 
Published: June 2023

Cette contribution s’appuie sur notre recherche doctorale menée entre 2018 et 2020, dans le domaine des sciences du langage, intitulée « Étude sur la culture littéraire plurielle et plurilingue des élèves : l’exemple du débat interprétatif littéraire ». Nous avons introduit la notion de culture littéraire plurilingue dans l’enseignement du français langue seconde au collège. En effet, nous considérons que les élèves allophones, qui arrivent dans le système éducatif français, ont une culture littéraire qu’ils ont construite dans leur pays d’origine, dans leur langue d’origine. Que faire de cette culture littéraire dans les dispositifs d’accueil ? Que faire de cette culture littéraire dans un cours de français ? Nous nous pencherons tout d’abord sur l’accueil des élèves allophones à l’École et sur les dispositifs mis en place en nous appuyant sur les différents documents officiels conçus par l’Éducation Nationale. Puis, nous reviendrons sur la notion d’allophonie et sur les apports d’une éducation dite plurilingue. Enfin, nous présenterons notre étude sur la culture littéraire plurielle et plurilingue des élèves allophones et le dispositif que nous avons mis en place afin de valoriser cette culture littéraire plurilingue. Comment laisser la place à leur culture littéraire plurilingue dans un contexte considéré très souvent, à tort, comme uniquement francophone ? Quel impact ce genre de pratique peut-elle avoir sur leur apprentissage du français langue seconde mais également sur le processus d’inclusion ? Comment les enseignants de lettres en classes ordinaires peuvent-ils mettre en place une telle pratique ?

Метою дослідження є реконструкція політики дерусифікації та українізації в 1917–1924 рр. на теренах Чернігівщини та роль Глухівського учительського інституту в цьому процесі; методологічну основу роботи складають загальнонаукові (аналіз, синтез, дедукція, індукція, системний підхід) та спеціально-історичні (історико-генетичний, історико-порівняльний) методи й принципи історизму, суб’єктивізму, оптимізації обсягу інформації. Новизна роботи. У статті вперше проаналізовано зміст та кадрове забезпечення українізації Глухівського інституту в 1917–1924 рр. Для повноти розкриття теми в окремих випадках хронологічні межі розширено до другої половини 1920-х рр. Висновки. Установлено, що в 1917 р. Генеральний секретаріат розпочав в освітній сфері політику дерусифікації, яка набувала рис поміркованої українізації у сфері шкільної та університетської освіти. Відповідно до нового курсу восени–взимку 1917 р. керівництво Глухівського інституту вносить зміни в навчальну програму й у закладі починають викладатися курси української мови та літератури. У 1918–1919 рр. кількість українознавчих курсів розширюється за рахунок історії української культури та історії України. Із встановленням радянської влади відбулося корегування політики дерусифікації в освітній сфері, і українознавчі дисципліни викладали тільки для студентів-гуманітаріїв інституту. З’ясовано, що в 1923 р. проголошення курсу коренізації в УСРР створило передумови для подальшого реформування освітянської сфери. На жаль, політика українізації гальмувалася відсутністю достатньої кількості навчально-методичної літератури та добре підготовлених кадрів в інституті. Утім, 1926 р. ситуація істотно покращилася, і курси фізики та біології почали викладати українською мовою. Серед викладачів українознавчих курсів в інституті 1917–1924 рр. варто згадати Д.Г. Онацького, Є.Г. Сагарду, А.В. Кириченка, Т.В. Пашкевич (українська мова та література), В.К. Федоренка (історія).

The first Colombian records of the Antillean Nighthawk (Chordeiles gundlachii), with notes on migrant Chordeiles in South America

Published: June 2023

The Antillean Nighthawk (Chordeiles gundlachii), a species very similar to the Common Nighthawk (Chordeiles minor), was presumed to migrate to South America following breeding in the Caribbean region. However, no concrete evidence of its presence there existed prior to 2018, when a geolocation study revealed the migration route and wintering area in western Brazil of an individual, including its possible presence in the Venezuelan-Colombian border during its fall migration. We found two misidentified specimens of this species in series of C. minor in two Colombian ornithological collections that definitely established its presence in Colombia. We also compare the migration paths of C. gundlachii with those of a similar study of the migrations of C. minor. We highlight the scarcity of spring specimens of both species in these collections, a pattern also evident in spatiotemporal modeling based on community science data. We suggest that further examination of series of C. minor in other South American collections, including genetic analyses, wider movement tracking studies, and stable isotope analyses could clarify the nonbreeding distributions of both migratory nighthawks. In addition, Antillean Nighthawk flight calls are distinctive and a good indicator of its presence thus can help to detect it and better understand its migration routes.
Once Again on Aristotle and the Identity of the Athenian Nomothetai. A Response to Gertrud Dietze-Mager
Authors: Canevaro Mirko , Esu Alberto 
Published: June 2023

This article is a short response to a recent contribution by Dietze-Mager in Erga-Logoi 10.2. There, within a larger discussion of the reliability of the Aristotelian Athenaion Politeia as a historical source, Dietze-Mager argues against our proposed identification of the Athenian nomothetai with a special session of the Assembly. In response, we start with a concise summary of our interpretation of the constitutional stages in the Athenaion Politeia in light of the socio-economic methodology of Politics IV, and clarify the role of Aristotle’s political theory in our reconstruction. We then provide a close reading of some key evidence about the identity of the Athenian nomothetai (particularly Aeschin. III 38-40). We demonstrate that Dietze-Mager’s proposed reading of the relevant passage is linguistically and syntactically problematic, arguing that the only possible interpretation of the relevant procedure as described at Aeschin. III 38-40 involves identifying the nomothetai with a special lawmaking session of the Assembly.
Voltage Quality Analysis on Power Transmission Networks: A Case Study of 330kV Power Transmission Networks in Nigeria
Authors: Olabisi Patrick O. , Ayeni Gbenga 
Published: June 2023

The 330kV power transmission system in Nigeria is associated with numerous problems ranging from voltage instability, ageing network, long and weak transmission lines and insulators, absence of protection schemes on the distribution network, lack of spinning reserve to compensate for power shortages, obsolete substation equipment, and higher power losses which substantially affect the reliability of power supply in Nigeria. This study aimed at analysing this scenario and to propose stability improvement measures in the power Network. Voltage instability is a major factor responsible for several system collapse and blackout experienced in the country. This work used necessary data obtained from the National Control Centre (NCC) of Transmission Company of Nigeria (TCN) for load flow simulation with the help of MATLAB R2021a software. Newton-Raphson iterative technique was used to carry out the load flow analysis due to its ability to converge faster with less iteration than Gauss-seidel and fast decoupled iterative techniques. The simulation results revealed that buses 4 (Akangba), 5 (Jos), 7 (Ikeja-west), 10 (Alagbon), 19 (Damaturu), 23 (Sakette), 28 (Ajah), 33 (Oke-Aro), 34 (Ayede) and 42 (Lekki) violate the acceptable limits as its voltage magnitude falls below the standard limit of 0.95-1.05pu. It was also observed that buses 6 (Kaduna), 13 (Yola), 16 (Gombe), 22 (Kano) and 34 (Ayede) are close to the point of instability as their voltage magnitudes are between 0.95 and 0.96 pu. These buses need urgent compensation if stability improvement in the entire Nigerian transmission system is to be achieved.

AbstractThe pandemic of coronavirus disease 2019 (COVID‐19) reflects the great significance of rapid and accurate detection of pathogens by new sensing technologies. Antibody based biosensors with high sensitivity comparable to golden standard polymerase chain reaction (PCR) and miniaturized device features allow the detection of pathogens in portable and flexible formats. Herein, flexible metal oxide electrolyte‐gated field‐effect transistors (EGFETs) are reported to serve as the biosensors for rapid and ultrasensitive severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) detection. The semiconducting layer of the EGFETs associates with hybrid material of PEI doped metal oxides that not only improves the transistor performance, but also regulates microstructure forming higher surface‐to‐volume ratio, which brings more antibodies immobilization, resulting in higher sensitive, and faster response for detecting SARS‐CoV‐2. Comprehensive studies of materials and interfacing engineering of the EGFETs not only build the strong foundation for the EGFET sensors to show excellent sensitivity with a limit of detection from 0.14 fg ml−1 for SARS‐CoV‐2 S1 proteins, and 0.09 copies µl−1 for SARS‐CoV‐2 viruses, but also offer good mechanical properties to enable thin, soft flexible sensing platforms. This work provides a new strategy from materials to devices as innovative schemes for virus/pathogens detection.

AbstractBio‐inspired neuromorphic vision sensors, integrating optical sensing, and processing functions have attracted significant attention for developing future low‐power and high‐efficiency imaging systems. However, the compulsory electrical signal modulation to achieve inhibitory behaviors in most reported neuromorphic vision sensors results in additional hardware and computational latency. Herein, bidirectional photoresponsive optoelectronic synapses based on In2O3/Al2O3/Y6 phototransistors are achieved, realizing all‐optical‐configured synaptic weight updates enabled by dual photogates. The inhibitory and excitatory photoresponses originate from the photogating effects provided by trapped photogenerated electrons in Al2O3 under near‐infrared light and the ionized oxygen vacancies in In2O3 under ultra‐violet light, respectively. The bidirectional phototransistor illustrates outstanding optoelectronic synaptic characteristics with low nonlinearity and asymmetry, demonstrating high efficiencies in both preprocessing and postprocessing tasks, such as noise reduction, contrast enhancement, and pattern recognition. The proposed dual‐photogate optoelectronic synapses provide effective strategies to construct high‐efficiency neuromorphic vision sensors and in‐sensor computing systems.

AbstractProducing efficient blue and deep blue perovskite LEDs (PeLEDs) still represents a significant challenge in optoelectronics. Blue PeLEDs still have problems relating to color, luminance, and structural and electrical stability so new materials are needed to achieve better performance. Recent reports suggest using low n states (n = 1, 2, 3) to achieve blue electroluminescence in Ruddlesden–Popper (RP) perovskite films. However, there are fewer reports on the other quasi‐2D structure, Dion–Jacobson (DJ) perovksites, despite their highly desirable optical properties, due to the difficulty in achieving charge injection. To resolve this issue, herein, w e have mixed DJ phase precursors, propane‐1,3‐diammonium (PDA) bromide into RP phase perovskites and fabricated low‐dimensional PeLEDs. It is found that these specific precursors aid in suppressing both the low n (n = 1) and high n (n ≥ 4) quasi‐2D RP phases and is an effective strategy in blue‐shifting sky‐blue RP perovskites into the sub‐470 nm region. With optimization of the PDA concentration and device layers, it is achieved an external quantum efficiency of 1.5% at 469 nm and stable electroluminescence for the first deep blue PeLED to be reported using DJ perovskites.

AbstractStrong metal‐support interaction (SMSI) greatly improves the performances of various supported metal nanoparticle catalysts. Classical SMSI relies on the oxide species with substoichiometric oxygen concentration, which prefers to retreat off in humid and oxidative atmospheres. A SMSI is reported with oxygen‐saturated overlayers on Au/TiO2catalyst achieved by steaming treatment, an opposite condition to the classical SMSI formation. Through a combination of experimental and theoretical methods, this study demonstrates that the strong interactions between the TiOxHy(x≥2) species and Au surface cause the support migration to encapsulate Au nanoparticles. The oxygen‐saturated oxide overlayers are stable in oxidative, reductive, and humid atmospheres, providing great vitality to stabilize metal nanoparticle catalysts under varied and complex reaction conditions to outperform the classical SMSI.

AbstractCreating 3D‐engineered macroscopic architectures while inheriting the superior properties of individual building blocks remains one of the fundamental challenges in nanotechnology. Stable covalent interconnection between micro/nanoblocks is a desired but underexplored strategy to meet the challenges, rather than current dependently‐used weak physical forces or organic cross‐linking, which disrupts the continuity of chemical composition and electrical properties. Herein, a novel layer‐by‐layer covalent growth protocol is developed to construct all‐graphene macrostructures (AGM) with micro‐to‐macro inheritable electrical properties by laser‐assisted covalent linkage of polyethersulfone‐derived 3D porous graphene microblocks without introducing any catalysts, templates, and additives. Creatively, along with graphene generation and inter‐layer bonding, a quality optimization process is integrated into one‐step laser irradiation, which is unique and efficient for synthesizing high‐crystalline graphene. With the covalently nondestructive bridge and free of non‐graphene foreign phase impurities, AGM shows unprecedented electrical conductivity, especially a more than 100‐fold improvement in cross‐layer conductivity compared with non‐covalent assembly. Furthermore, the covalent growth mechanism of AGM is clarified by molecular dynamics simulations. Finally, the application efficacy of AGM with enhanced isotropic conductivity is verified by using it as a supercapacitor electrode. This methodology enables the as‐obtained AGM to possess the potential for high‐performance‐pursuing, multi‐disciplinary, or large‐scale applications.

Published: June 2023

AbstractBlue conjugated polymers‐based OLEDs with both high efficiency and low efficiency roll‐off are under big challenge. Herein, a strategy of local conjugation is proposed to construct high‐efficiency blue‐emitting conjugated polymers, in which the conjugation degree of polymeric backbones is adjusted by inserting different spacers. In this way, the energy level of triplet state and the energy transfer direction of the polymeric main‐chains can be effectively regulated. Benefiting from such fine regulation, the prepared alternative copolymers Alt‐PB36 with local conjugated main‐chains can better suppress the accumulation of long‐lived triplet excitons comparing with the complete conjugated polymers. The higher PLQY of Alt‐PB36 also verifies the effective energy transfer from the polymeric main‐chains to the TADF units. Accordingly, Alt‐PB36 based solution‐processed OLEDs achieve an EQEmax of 11.6% and a very low efficiency roll‐off of 2.8% at 100 cd m−2 and 15.2% at 500 cd m−2. This result represents the best efficiency among blue light‐emitting conjugated polymer‐based OLEDs so far under high luminance.

AbstractThis paper reports on the light amplification of NaGdF4:Yb,Er,Ce@NaGdF4:Yb,Nd@NaGdF4 core–shell–shell downconversion nanoparticles (CSS‐DCNPs) in the near‐infrared second biological window (NIR‐II: 1000–1700 nm) by plasmonic nanostructures. Through a precisely controlled plasmonic metallic nanostructure, fluorescence from Yb3+ induced 1000 nm emission, Nd3+ induced 1060 nm emission, and Er3+ induced 1527 nm emission are enhanced 1.6‐fold, 1.7‐fold, and 2.2‐fold, respectively, under an 808 nm laser excitation for the CSS‐DCNPs coupled with a gold hole‐cap nanoarray (Au‐HCNA), while the Er3+ induced 1527 nm emission under a 980 nm laser excitation is enhanced up to 6‐fold. To gain insight into the enhancement mechanism, the plasmonic modulation of Er3+ induced NIR‐II emission at 1550 nm under 980 nm excitation is studied by FDTD simulation and lifetime measurements, showing the observed fluorescence enhancement can be attributed to a combination of enhanced excitation and an increased radiative decay rate.

Published: June 2023

AbstractSelective reduction of nitro‐containing arenes and heteroarenes was achieved in 5 minutes at room temperature utilizing inexpensive NaBH4 as a hydrogen source and a newly developed Ni@N−C catalyst, obtained via a simple carbon coating process without the need for an external carbon source. A wide variety of nitro derivatives, including pharmaceutical molecules, was successfully reduced to the corresponding amines in yields ranging from 45% to 99% using the Ni@N−C catalyst under general batch conditions. The reactivity and selectivity of the nitro reduction were further enhanced by a continuous flow reaction system, especially when a newly designed Y‐type column was used, and the Osimertinib intermediate was produced on gram scale after 24 hours without any nickel metal contamination or silica gel chromatography purification.
