Prospective Implications of Extreme-ultraviolet Coronal Plumes for Magnetic-network Genesis of Coronal Heating, Coronal-hole Solar Wind, and Solar-wind Magnetic Field Switchbacks
Authors: Moore Ronald L. , Tiwari Sanjiv K. , Panesar Navdeep K. , Sterling Alphonse C. 
Published: March 2023

Abstract
We propose that coronal heating in EUV coronal plumes is weaker, not stronger, than in adjacent nonplume coronal magnetic funnels. This expectation stems from (i) the observation that an EUV plume is born as the magnetic flux at the foot of the plume’s magnetic funnel becomes tightly packed, and (ii) the observation that coronal heating in quiet regions increases in proportion to the coastline length of the underlying magnetic network. We do not rule out the possibility that coronal heating in EUV plumes might be stronger, not weaker, but we point out how the opposite is plausible. We reason that increasing coronal heating during plume birth would cause co-temporal increasing net upward mass flux in the plume, whereas decreasing coronal heating during plume birth would cause co-temporal net downward mass flux in quiet-region plumes and co-temporal decrease in net upward mass flux or even net downward mass flux in coronal-hole plumes. We further reason that conclusive evidence of weaker coronal heating in EUV plumes would strengthen the possibility that magnetic-twist waves from fine-scale magnetic explosions at the edges of the magnetic network (1) power much of the coronal heating in quiet regions, and (2) power most of the coronal heating and solar-wind acceleration in coronal holes, with many twist waves surviving to become magnetic field switchbacks in the solar wind from coronal holes.
Interstellar Objects from Broken Dyson Spheres
Authors: Loeb Abraham 
Published: March 2023

Abstract
Without extensive maintenance, Dyson spheres inevitably disintegrate by asteroid impacts over billions of years. The resulting fragments would appear as anomalous interstellar objects, potentially sharing the unusual shape and motion of 1I/‘Oumuamua or the unusual material strength of the first two interstellar meteors, IM1 and IM2. If the Dyson sphere's tiles are light sails, the number of fragments could exceed that of interstellar asteroids because of their reduced escape speed from the star and the increase in stellar luminosity during the red giant phase.
Le langage idéologique des objets. Fabriquer la morale dominante dans le roman réaliste
Authors: Vodoz Joséphine 
Published: March 2023

Cet article prolonge une réflexion entamée par Claude Duchet sur la dimension idéologique des objets dans le roman réaliste. Il s’agit, avec l’apport anthropologique des Material Culture Studies , de définir une idéologie matérielle, c’est-à-dire un langage formel des objets par lequel ils véhiculent des valeurs et des significations socioculturelles. On montre ensuite que le roman réaliste est un lieu privilégié de mise en récit et de réflexion autour des idéologies matérielles émergentes. En particulier les scènes de fabrique sont les lieux où se produisent les objets de la consommation courante et l’idéologie dominante. On s’arrête en particulier sur deux exemples tirés du Ventre de Paris (1873) et de L’Éducation sentimentale (1869).
Revenances de Baudelaire
Authors: Trudel Éric 
Published: March 2023

Le Revenant , petit récit publié par Éric Chauvier en 2018, imagine le zombi Charles Baudelaire errant, hagard, dans le Paris du xxi e siècle. Les passants pressés qui le frôlent ignorent qu’il fut le « plus grand témoin » de la modernité, et restent incapables de le distinguer de tous ceux que la capitale abandonne dans ses marges. Cet article prend à la lettre la prémisse par laquelle Chauvier nous invite à considérer l’actualité de Baudelaire en le réveillant parmi nous « piteusement déclassé » en revenant, afin de revenir à la poésie baudelairienne et à son pouvoir, ce qu’il en reste aujourd’hui et ce qui peut-être en revient. De quoi peut-on espérer se ressaisir chez Baudelaire quand on l’imagine sous les traits d’un mort-vivant ?
Comprendre les stratégies d’ambiguïté des clients professionnels générant un risque de corruption : cas de recherche-intervention dans le secteur bancaire
Authors: Cailleba Patrice , Dufour Nicolas 
Published: March 2023

La corruption fait l’objet de beaucoup d’attention des media en France comme à l’international. Pourtant, peu d’études académiques ont été menées sur le sujet. Mettant de côté les pratiques hypocrites, nous nous intéressons aux pratiques d’ambiguïté stratégique, en particulier celles des clients professionnels en France. De même, nous portons notre attention aux réponses – rarement étudiées jusqu’ici – des salariés face à ces stratégies d’ambiguïté ouvrant potentiellement sur des situations de corruption. A partir des résultats d’une étude longitudinale récente consacrée à la mafia italienne, l’objet de cet article est double : il s’agit (1) d’examiner théoriquement les stratégies d’ambiguïté de certaines organisations, puis (2) de considérer les réponses des salariés face à ces stratégies lors de relations commerciales avec des entreprises. Ce faisant, nous détaillons et illustrons les différentes formes que peut prendre cette ambiguïté stratégique, à savoir l’opacité qui empêche toute compréhension aisée, l’équivocité qui joue de la diversité des discours rationnalisants et l’absurdité qui favorise les raisonnements paradoxaux. Au cours de notre réflexion, nous abordons également la question du silence organisationnel, tout en en soulignant les implications et les limites pour les individus concernés. Nous basons notre travail sur une recherche-intervention conduite en 2020 dans le secteur bancaire auprès de 423 personnes, essentiellement des cadres et des dirigeants, intervention qui a donné lieu à près d’une centaine d’heures d’entretiens et à 31 entretiens de groupe.
L’adéquation personne/environnement sous la lentille des professionnels en gestion des ressources humaines
Authors: Deschênes Andrée-Anne 
Published: March 2023

L’adéquation personne/environnement s’est taillé une place centrale dans la littérature en GRH et en psychologie organisationnelle. Elle s’avère essentielle à la compréhension des attitudes et des comportements des employés au travail. Si ses effets bénéfiques ont largement été documentés, la connaissance des professionnels en ressources humaines (PRH) à l’égard de ce concept ainsi que son inclusion dans les pratiques de gestion des ressources humaines ont été peu abordées. Cet article a pour objectif de faire l’examen de la connaissance des PRH au regard de la définition de l’adéquation individu/environnement, puis de brosser le portrait de son intégration dans les pratiques. Il propose un portrait descriptif et analytique de la définition du concept par les PRH, et de son recours dans les pratiques au regard de quatre types d’adéquation individu/environnement : individu/emploi, individu/organisation, individu/groupe et subordonné/superviseur. Les résultats sont issus de données quantitatives et qualitatives recueillies par questionnaire auprès de 106 PRH exerçant dans des organisations québécoises. Ils indiquent que les PRH définissent surtout l’adéquation comme la similarité ou la correspondance des valeurs, et que l’inclusion de l’adéquation dans les activités de recrutement repose surtout sur la diffusion des valeurs, de la vision et de la mission de l’organisation. En matière de sélection, l’intuition des recruteurs prime sur la mesure formelle des attributs du candidat (valeurs, personnalité, objectif). L’adéquation avec l’emploi est le type d’adéquation qui guide le plus les autres activités de GRH (comme la formation et la gestion des performances). Dans un contexte où les organisations déploient des efforts considérables en matière d’attraction et de fidélisation du personnel, cet article éclaire la théorie et la pratique quant aux pratiques de gestion des ressources humaines déployées en vue de favoriser l’adéquation individu/environnement.
Artificial Intelligence System in Aid of Pedagogical Engineering for Knowledge Assessment on MOOC Platforms: Open EdX and Moodle
Authors: Bachiri Younes-Aziz , Mouncif Hicham 
Published: March 2023

The aim of this research is to provide a novel educational model with the goal of reducing the expenses associated with manual question production and meeting the demand for a continual supply of new questions on MOOC platforms such as Moodle or Open EDX. We considered integrating machine-learning methods with natural language processing in order to increase the number and validity of assessing questions. To accomplish this, we developed a system that generates multilingual questions automatically.
Various kinds of evaluation were conducted with two factors in mind: evaluating MOOC learners' competency and the similarity of the generated questions to those created by humans. The first evaluation is based on subjective judgment by three MOOC creators, while the second is based on replies from MOOC participants on machine-generated and human-created questions. Both evaluations revealed that the machine-generated questions performed on par with the human-created questions in terms of evaluating skills and similarity. Moreover, the results demonstrate that most of the produced questions (up to 82 percent) enhance e-assessment when the new suggested technology is used.

Abstract—Due to advances in education and informatics, online learning is now becoming a direction for teaching reform in universities. This in turn put learning engagement at the forefront of educational literature: online teaching activity has become a key component of teaching due to its strong influence on learning engagement and outcomes. This study analyzes the influences of teachers’ online teaching ability (teaching design ability, resource development ability, teaching implementation ability, teaching evaluation ability, teaching reflection ability) on learning engagement across different majors and grade-levels. Research results showed abilities on teaching design, teaching implementation, teaching evaluation, and teaching reflection have significantly positive influences on learning engagement. These results provide important references in further exploring influencing mechanism of teaching activities on learning engagement, improve online teaching ability of teachers, and increase online learning engagement of students.

Abstract
CMV infection alters NK cell phenotype and function toward a more memory-like immune state. These cells, termed adaptive NK cells, typically express CD57 and NKG2C but lack expression of the FcRγ-chain (gene: FCER1G, FcRγ), PLZF, and SYK. Functionally, adaptive NK cells display enhanced Ab-dependent cellular cytotoxicity (ADCC) and cytokine production. However, the mechanism behind this enhanced function is unknown. To understand what drives enhanced ADCC and cytokine production in adaptive NK cells, we optimized a CRISPR/Cas9 system to ablate genes from primary human NK cells. We ablated genes that encode molecules in the ADCC pathway, such as FcRγ, CD3ζ, SYK, SHP-1, ZAP70, and the transcription factor PLZF, and tested subsequent ADCC and cytokine production. We found that ablating the FcRγ-chain caused a modest increase in TNF-α production. Ablation of PLZF did not enhance ADCC or cytokine production. Importantly, SYK kinase ablation significantly enhanced cytotoxicity, cytokine production, and target cell conjugation, whereas ZAP70 kinase ablation diminished function. Ablating the phosphatase SHP-1 enhanced cytotoxicity but reduced cytokine production. These results indicate that the enhanced cytotoxicity and cytokine production of CMV-induced adaptive NK cells is more likely due to the loss of SYK than the lack of FcRγ or PLZF. We found the lack of SYK expression could improve target cell conjugation through enhanced CD2 expression or limit SHP-1–mediated inhibition of CD16A signaling, leading to enhanced cytotoxicity and cytokine production.

Published: March 2023

Madam, Corona Virus Disease (COVID-19), a pandemic, has been a global concern and it is a highly contagious respiratory illness that has been fatal to around 6 million lives. Although everyone is prone to get infected by COVID-19, the fact that is often overlooked is that newborns, infants and toddlers are as likely to get COVID-19 as adults.
Babies younger than one year old might have a higher chance to get COVID-19 than older children. (1) According to a case report by Alzamora et al. mother infected with COVID-19 can also, in sporadic cases, pass the disease to her baby. (2) Infants are also at risk of getting infected shortly after birth, reason being exposure to sick caregivers. Most newborn, infants and toddlers who fall prey to COVID-19 have mild or no symptoms engendering many new cases, but serious cases have also occurred leading to hospitalization. Hospitalization is associated more with the omicron variant than the delta variant. According to Morbidity and Mortality Weekly Report (MMWR) by the Centrs for Disease Control and Prevention (CDC), hospitalization of U.S. infants and children aged 0-4 years was five times more during omicron predominance than during delta surge. (3)
To overcome such cases, CDC recommends COVID-19 vaccine and backs Pfizer’s and Moderna’s COVID-19 shots for children aged six month to five years. (4) These vaccines can prevent complications like Multisystem Inflammatory Syndrome and Long COVID, which can be debilitating for young children. Vaccination can also protect children, which in turn minimize the possibility of transmission of disease to others. Furthermore, U.S. Food and Drug Administration (FDA) has also expanded the approval of the COVID-19 treatment Velkury (Remdesivir) to include pediatric patients 28 days of age and older weighing at least 3 kilograms with positive results of direct SARS-CoV-2 viral testing. (5)
With COVID-19 rearing its head again in Pakistan, vaccination of vulnerable populations like newborns, infants and toddlers must be an urgent step to stem the spread of virus because tomorrow may be too late. Besides, Remdesivir, which was previously approved for certain adults, can now be put to good use for treating infants as young as 28 days old so that progression in hospitalization and critical illness in pediatric patients of Pakistan be cut down.
