Coagulation Instability in Protoplanetary Disks: A Novel Mechanism Connecting Collisional Growth and Hydrodynamical Clumping of Dust Particles
Authors: Tominaga Ryosuke T. , Inutsuka Shu-ichiro , Kobayashi Hiroshi
Published: December 2021

We present a new instability driven by a combination of coagulation and radial drift of dust particles. We refer to this instability as “coagulation instability” and regard it as a promising mechanism to concentrate dust particles and assist planetesimal formation in the very early stages of disk evolution. Because of dust-density dependence of collisional coagulation efficiency, dust particles efficiently (inefficiently) grow in a region of positive (negative) dust density perturbations, leading to a small radial variation of dust sizes and as a result radial velocity perturbations. The resultant velocity perturbations lead to dust concentration and amplify dust density perturbations. This positive feedback makes a disk unstable. The growth timescale of coagulation instability is a few tens of orbital periods even when dust-to-gas mass ratio is on the order of 10−3. In a protoplanetary disk, radial drift and coagulation of dust particles tend to result in dust depletion. The present instability locally concentrates dust particles even in such a dust-depleted region. The resulting concentration provides preferable sites for dust–gas instabilities to develop, which leads to further concentration. Dust diffusion and aerodynamical feedback tend to stabilize short-wavelength modes, but do not completely suppress the growth of coagulation instability. Therefore, coagulation instability is expected to play an important role in setting up the next stage for other instabilities, such as streaming instability or secular gravitational instability, to further develop toward planetesimal formation.

Although it is well established that some extragalactic radio sources are time-variable, the properties of this radio variability, and its connection with host galaxy properties, remain to be explored—particularly for faint sources. Here we present an analysis of radio variable sources from the CHILES Variable and Explosive Radio Dynamic Evolution Survey (CHILES VERDES)—a partner project of the 1.4 GHz COSMOS H i Large Extragalactic Survey. CHILES VERDES provides an unprecedented combination of survey depth, duration, and cadence, with 960 hr of 1–2 GHz continuum VLA data obtained over 209 epochs between 2013 and 2019 in a 0.44 deg2 section of the well-studied extragalactic deep field, COSMOS. We identified 18 moderate-variability sources (showing 10%–30% flux density variation) and 40 lower-variability sources (2%–10% flux density variation). They are mainly active galactic nuclei (AGNs) with radio luminosities in the range of 1022–1027 W Hz−1, based on cross-matching with COSMOS multiwavelength catalogs. The moderate-variability sources span redshifts z = 0.22–1.56, have mostly flat radio spectra (α > −0.5), and vary on timescales ranging from days to years. The lower-variability sources have similar properties, but generally have higher radio luminosities than the moderate-variability sources, extending to z = 2.8, and have steeper radio spectra (α < −0.5). No star-forming galaxy showed statistically significant variability in our analysis. The observed variability likely originates from scintillation on short (∼week) timescales, and Doppler-boosted intrinsic AGN variability on long (month–year) timescales.
Monitoring Of Jets in Active Galactic Nuclei with VLBA Experiments. XVIII. Kinematics and Inner Jet Evolution of Bright Radio-loud Active Galaxies

Published: December 2021

We have analyzed the parsec-scale jet kinematics of 447 bright radio-loud active active galactic nuclei (AGN), based on 15 GHz Very Long Baseline Array (VLBA) data obtained between 1994 August 31 and 2019 August 4. We present new total intensity and linear polarization maps obtained between 2017 January 1 and 2019 August 4 for 143 of these AGN. We tracked 1923 bright features for five or more epochs in 419 jets. The majority (60%) of the well-sampled jet features show either accelerated or nonradial motion. In 47 jets there is at least one nonaccelerating feature with an unusually slow apparent speed. Most of the jets show variations of 10°–50° in their inner jet position angle (PA) over time, although the overall distribution has a continuous tail out to 200°. AGN with spectral energy distributions peaked at lower frequencies tend to have more variable PAs, with BL Lac objects being less variable than quasars. The Fermi Large Area Telescope (LAT) gamma-ray-associated AGN also tend to have more variable PAs than the non-LAT AGN in our sample. We attribute these trends to smaller viewing angles for the lower spectral peaked and LAT-associated jets. We identified 13 AGN where multiple features emerge over decade-long periods at systematically increasing or decreasing PAs. Since the ejected features do not fill the entire jet cross section, this behavior is indicative of a precessing flow instability near the jet base. Although some jets show indications of oscillatory PA evolution, we claim no bona fide cases of periodicity since the fitted periods are comparable to the total VLBA time coverage.
Compositional Variation of the Dayside Martian Ionosphere: Inference from Photochemical Equilibrium Computations
Authors: Wu Xiaoshu , Cui Jun , Niu Dandan , Ren Zhipeng , Wei Yong
Published: December 2021

The Martian ionosphere plays a crucial role in driving the interactions of the planet with solar photons and solar wind particles. The variations of the dayside Martian ionosphere with several controlling factors, including the solar extreme ultraviolet radiation, the background atmosphere, and the underlying thermal structure, have been the topic of extensive research in terms of electron distribution. In contrast, how the ionospheric composition varies has not been systematically investigated, a topic that is attempted in this study based on photochemical equilibrium computations performed at 100–200 km altitude, including a large number of reactions. Our calculations reveal the following compositional variations as natural outcomes of the ionospheric chemistry on Mars. (1) With increasing solar irradiance, the proportions of the majority of nonterminal ions are enhanced at the expense of reduced proportions of terminal ions, including

O

2

+

, HCO+, NO+, and H3O+. (2) At high electron temperatures, the proportion of NO+ is modestly reduced, whereas the proportions of the other species are nearly unaffected. (3) The response of the ionospheric composition to the upper atmospheric composition is complicated, showing the strong negative response of many trace ions to ambient CO2, O, and CO, as well as the strong positive response of protonated ions to H2, nitrogen-bearing ions to N and N2, water-group ions to H2O, and

HO

+

to O2. As an application of the model results, the recent ion measurements made on board the Mars Atmosphere and Volatile Evolution are used to provide hints about the realistic composition of the Martian upper atmosphere.
Magnetic Fields and Accreting Giant Planets around PDS 70
Authors: Hasegawa Yasuhiro , Kanagawa Kazuhiro D. , Turner Neal J.
Published: December 2021

Recent high-spatial/spectral-resolution observations have enabled the formation mechanisms of giant planets to be constrained, especially at the final stages. The current interpretation of such observations is that these planets undergo magnetospheric accretion, suggesting the importance of planetary magnetic fields. We explore the properties of accreting, magnetized giant planets surrounded by their circumplanetary disks, using the physical parameters inferred for PDS 70 b/c. We compute the magnetic field strength and the resulting spin rate of giant planets and find that these planets may possess dipole magnetic fields of either a few 10 G or a few 100 G; the former is the natural outcome of planetary growth and radius evolution, while the resulting spin rate cannot reproduce the observations. For the latter, a consistent picture can be drawn, where strong magnetic fields induced by hot planetary interiors lead both to magnetospheric accretion and to spin-down due to disk locking. We also compute the properties of circumplanetary disks in the vicinity of these planets, taking into account planetary magnetic fields. The resulting surface density becomes very low, compared with the canonical models, implying the importance of radial movement of satellite-forming materials. Our model predicts a positive gradient of the surface density, which invokes traps for both satellite migration and radially drifting dust particles. This work thus concludes that the final formation stages of giant planets are similar to those of low-mass stars such as brown dwarfs, as suggested by recent studies.

Recent work has revealed two classes of globular clusters (GCs), dubbed Type I and Type II. Type II GCs are characterized by both a blue and a red red giant branch composed of stars with different metallicities, often coupled with distinct abundances in the slow neutron-capture elements (s-elements). Here we continue the chemical tagging of Type II GCs by adding the two least massive clusters of this class, NGC 1261 and NGC 6934. Based on both spectroscopy and photometry, we find red stars in NGC 1261 to be slightly enhanced in [Fe/H] by ∼0.1 dex and confirm that red stars of NGC 6934 are enhanced in iron by ∼0.2 dex. Neither NGC 1261 nor NGC 6934 show internal variations in the s-elements, which suggests a GC mass threshold for the occurrence of s-process enrichment. We found a significant correlation between the additional Fe locked in the red stars of Type II GCs and the present-day mass of the cluster. Nevertheless, most Type II GCs retained a small fraction of Fe produced by SNe II, lower than the 2%; NGC 6273, M54, and ω Centauri are remarkable exceptions. In the Appendix, we infer for the first time chemical abundances of lanthanum, assumed as representative of the s-elements, in M54, the GC located in the nucleus of the Sagittarius dwarf galaxy. Red-sequence stars are marginally enhanced in [La/Fe] by 0.10 ± 0.06 dex, in contrast with the large [La/Fe] spread of most Type II GCs. We suggest that different processes are responsible for the enrichment in iron and s-elements in Type II GCs.
The First Retrieval of a Substellar Subdwarf: A Cloud-free SDSS J125637.13–022452.4

We present the first retrieval analysis of a substellar subdwarf, SDSS J125637.13−022452.4 (SDSS J1256−0224), using the Brewster retrieval code base. We find SDSS J1256−0224 is best fit by a cloud-free model with an ion (neutral H, H−, and electron) abundance corresponding to

Fe

ion

=

. However, this model is indistinguishable from a cloud-free model with

and a cloud-free model with

assuming a subsolar carbon-to-oxygen ratio. We are able to constrain abundances for H2O, FeH, and CrH, with an inability to constrain any carbon-bearing species likely due to the low metallicity of SDSS J1256−0224. We also present an updated spectral energy distribution (SED) and semiempirical fundamental parameters. Our retrieval- and SED-based fundamental parameters agree with the Baraffe low-metallicity evolutionary models. From examining our “rejected” models (those with ΔBIC > 45), we find that we are able to retrieve gas abundances consistent with those of our best fitting model. We find the cloud in these poorer fitting “cloudy” models is either pushed to the bottom of the atmosphere or made optically thin.

In this Letter we report a discovery of a prominent flash of a peculiar overluminous Type Ia supernova, SN 2020hvf, in about 5 hr of the supernova explosion by the first wide-field mosaic CMOS sensor imager, the Tomo-e Gozen Camera. The fast evolution of the early flash was captured by intensive intranight observations via the Tomo-e Gozen high-cadence survey. Numerical simulations show that such a prominent and fast early emission is most likely generated from an interaction between 0.01 M
⊙ circumstellar material (CSM) extending to a distance of ∼1013 cm and supernova ejecta soon after the explosion, indicating a confined dense CSM formation at the final evolution stage of the progenitor of SN 2020hvf. Based on the CSM–ejecta interaction-induced early flash, the overluminous light curve, and the high ejecta velocity of SN 2020hvf, we suggest that the SN 2020hvf may originate from a thermonuclear explosion of a super-Chandrasekhar-mass white dwarf (“super-M
Ch WD”). Systematical investigations on explosion mechanisms and hydrodynamic simulations of the super-M
Ch WD explosion are required to further test the suggested scenario and understand the progenitor of this peculiar supernova.
The Effect of Coronavirus Disease 2019 on Reproduction System and Fertility

As of October 9, 2020, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was recorded to have infected more than 235 countries and 36,361,054 people globally, and 1,056,186 people died from coronavirus disease 2019 (COVID-19). In early October 2020, it was reported that the rate of increase in new cases reached 300,000 cases per day. A scientific reference source about COVID-19 in pregnancy and fertility system based on the results of previous research. By conducting a literature search that was carried out until October 12, 2020, through the PubMed and Google Scholar databases using the keyword COVID-19 and pregnancy, 20 articles were used as a reference source. Human SARS-CoV appeared in China, causing a deadly epidemic 18 years ago. Novel coronavirus-2019 infects target cells by binding to angiotensin-converting enzyme 2 (ACE2) through its surface spike protein. nCoV-2 modulates ACE2 expression and causes serious injury, similar to SARS-CoV. There is the possibility that the SARS-CoV-2 mechanism can affect fertility on female, namely, SARS-CoV-2 can harm ovarian tissue and granulosa cells, and reduce ovarian function and quality of oocytes, and can make infertility or miscarriage; also damage the endometrial epithelium and affect early embryo implantation. COVID-19 is caused by SARS-CoV-2 which is an acute infectious disease that mostly affects the respiratory system, but can also attack the reproductive system.
Rediscovering the dancing semislug genus Cryptosemelus Collinge, 1902 (Eupulmonata, Ariophantidae) from Thailand with description of two new species
Authors: Pholyotha Arthit , Sutcharit Chirasak , Panha Somsak
Published: December 2021

Knowledge of Thai semislugs remains scarce, especially the dancing semislug genus Cryptosemelus. Prior to the present study, only a single species has been recognized with little available information. To address this knowledge gap, we surveyed for semislugs in western and southern Thailand, which yielded three species belonging to the genus Cryptosemelus. The little-known type species C. gracilis is redescribed herein, including a comparison with the type specimens. Two additional species, C. betarmonsp. nov. and C. tigrinussp. nov., are described as new to science. All three species are characterized by differences in their genital anatomy, especially with respect to anatomical details of the penis, epiphallus, and spermatophore. In addition, C. tigrinussp. nov. differs from C. gracilis and C. betarmonsp. nov. in the mantle color pattern.
Embrasser une complexité. Puissances de la dramaturgie et de l’incarnation dans une fictionnalisation de controverse sociétale par des comédien.nes écrivain.es de plateau
Authors: Souchier Flora
Published: December 2021

Comment la fictionnalisation théâtrale déplace-t-elle la perception du fond et de la forme d’une controverse sociétale entre des positions, cultures et intérêts parfois divergents ? À partir d’un week-end de recherche organisé dans le cadre du programme FORCCAST soutenu par l’ANR avec des comédien.nes écrivain.es de plateau, j’étudierai des ressources spécifiques de la fiction théâtrale et de son incarnation aux prises avec un débat éthique. Il sera donc question de création de personnages composites et de dramaturgies de l’indécidable, de jeux avec l’attention émotionnelle et intellectuelle des spectatrices et spectateurs, de ressorts féconds pour une pensée active, de mise en présence des dilemmes, de convocation de l’intime, de phénomènes d’identification-désidentification, d’exercices de pensée intriquée en actes, de propédeutique à l’émotionnel complexe.
La figure de la radicalité carcérale et ses portraits en régime médiatique
Authors: Saurier Delphine , Evain Christine
Published: December 2021

Cet article s’intéresse à la construction médiatique de la figure de la dangerosité du radical en monde carcéral. Cette construction est envisagée à travers l’analyse textométrique et sémio-discursive des portraits des individus dits radicalisés proposés par trois titres de presse magazine depuis les attentats de Charlie Hebdo . L’analyse montre la façon dont cette figure se décline dans des récits médiatiques, servie par un maillage intertextuel, une narration centrée sur la personne dite radicalisée qui fait personnage central et des mises en scènes photographiques. Ce faisant, une axiologie commune est confortée au détriment d’une mise en débat des contradictions sociales qui constituent ce monde.

Médecine africaine et médecine moderne : les défis d’une nécessaire coexistence
Authors: Ndjitoyap Ndam Elie Claude
Published: December 2021

L’histoire médicale des peuples d’Afrique est peu ou mal connue faute de documents écrits. La réalité révèle l’existence d’une médecine traditionnelle ancienne, certes empirique, mais qui a permis aux populations pour combattre les maladies qui affectaient la santé de leur famille et communautés. La pénétration sanitaire occidentale au 19 e siècle a mis les masses autochtones africaines au contact des Européens. Ceci a amené à la naissance d’une médecine dite moderne ou conventionnelle. Dès lors, on va donc assister en Afrique à la coexistence de deux savoirs, savoir-faire et savoir être en matière médicale. La médecine traditionnelle a ses spécificités, ses avantages et inconvénients. Quant à la médecine moderne, elle ne prend pas toujours en compte l’africanité du malade. Pour concilier les deux médecines, il faut faire appel à l’ethnomédecine, c’est-à-dire une anthropologie culturelle de la médecine en milieu africain. Ces défis demandent du bon sens et un certain réalisme.
Pandémie de Covid-19 et données de santé à échelle fine : révélation d’une approche indispensable
Authors: Cépré Ludovic
Published: December 2021

La pandémie de Covid-19 a montré l’importance de disposer de données de santé à échelle fine pour suivre la contagion et la limiter par des mesures locales. Mais elle a montré aussi à quel point manque une organisation capable d’activer, au plus près des citoyens, des moyens dédiés à l’adaptation des comportements de santé. Les structures de santé publique françaises sont pourtant de grande qualité, et convergent vers la création relativement simple d’un tel dispositif. Mais l’histoire de l’approche spatiale en santé, la structuration des bases de données, ou encore le poids de la mémoire d’enjeux passés ont retardé et pénalisé la mise en place de bases de données dédiées à la protection de la santé publique. Les inégalités spatiales de santé révèlent les inégalités sociales, et pointent les progrès majeurs encore à réaliser pour avoir les moyens d’y répondre, à une échelle très locale, selon une approche d’amélioration du niveau de santé.
Comprendre la mécanique des inégalités sociales de santé dans les trajectoires vers un diagnostic de cancer du foie : l’entrée par le non-recours
Authors: Beltran Grégory , Revil Hélèna , Costentin Charlotte
Published: December 2021

Cet article présente les premiers résultats d’une étude qualitative en sciences sociales qui analyse les trajectoires de patients atteints de carcinome hépatocellulaire – le plus fréquent des cancers primitifs du foie – au prisme du (non-) recours aux soins. Trois types de non-recours apparaissent dans ces trajectoires : la non-demande, la non-proposition et la non-réception. L’analyse de ces non-recours et de leurs mises en place permet d’aborder la question des inégalités sociales de santé, en prenant en compte la position sociale mais aussi l’origine sociale des personnes. Ces deux dimensions influencent à la fois l’adoption de comportements à risque et le rapport aux soins et au monde médical, et sont agissantes dans le (non-) recours aux soins, notamment dans les interactions avec les soignants. L’article souligne également l’intérêt d’approcher les trajectoires vers un diagnostic de cancer sur un temps long et l’importance des recherches qualitatives pour éclairer les données épidémiologiques mais aussi orienter les enquêtes quantitatives.
Catégorisation juridique des étrangers et inégalités sociales de santé : quelles sont les règles du jeu ?
Authors: Bories Claire
Published: December 2021

En matière d’accès aux soins, tous les étrangers ne sont pas égaux : certains malades étrangers rencontrent des difficultés faisant de l’accès aux soins un véritable « parcours du combattant » quand d’autres se voient accorder d’importantes facilités. Triste réalité. Cette différenciation est liée, principalement, à l’attribution de prérogatives de santé aux étrangers à travers le prisme des catégories juridiques, lesquelles deviennent le socle d’un traitement volontairement différencié entre les étrangers. Si chères aux juristes, ces catégories représentent, dans le domaine de l’accès aux soins, un matériel de jeu privilégié dont l’édification répond à une rationalité certaine. À travers l’amusante métaphore du jeu de société , il s’agira de mettre en lumière la manière dont le travail de catégorisation, appliqué aux étrangers, participe à la fabrique des inégalités sociales de santé entre les éléments catégorisés. Les étrangers seront les joueurs du jeu de l’accès aux soins, les catégories juridiques leurs équipes de jeu et les autorités nationales les « maîtresses du jeu ».

Published: December 2021

Menée au sein d’un centre de santé communautaire érigeant la médiation en santé en levier de lutte contre la fabrique des inégalités sociales de santé, notre recherche vise à comprendre en quoi les parcours de vie des médiateur·rice·s pair·e·s mobilisé·e·s, leurs socialisations incorporées et leurs expériences passées leur permettent de se construire un ethos d’agents socialisateurs en santé des publics vulnérables qu’ils·elles accompagnent. À partir de portraits configurationnels prenant appui sur les récits de leurs parcours biographiques, nous montrons que leur engagement dans ce nouveau métier nécessite, d’une part, qu’ils·elles se (re)construisent après les ruptures biographiques subies au cours de leurs trajectoires de vie et, d’autre part, qu’ils·elles parviennent à combiner dispositions antérieures, expériences vécues de la domination et construction de nouvelles ressources de proximité pour parvenir à agir et s’investir dans les situations présentes au sein de la Case de Santé de Toulouse.
La farce aristocratique et épiscopale
Authors: Koopmans Jelle
Published: December 2021

L’image traditionnelle de la farce est celle de spectacles populaires joués sur la place du marché. Pourtant, les farces ont aussi été jouées à la cour, devant des princes (et des princesses), mais aussi devant d’importants prélats. Les premiers joueurs de farces connus officient à la cour ; les ducs de Bourgogne ont leur « joueur de farce » et au début du xvi e  siècle, il y avait une troupe de joueurs du roi. Il est temps de réviser l’image traditionnelle de la farce : la farce aristocratique et épiscopale paraît bien avoir été un élément structural de ce genre.
La farce comme véhicule de la pensée religieuse de Marguerite de Navarre. Le cas du Mallade
Authors: Duhl Olga Anna
Published: December 2021

Au sein de la création dramatique de Marguerite de Navarre, la pièce non biblique Le Mallade (1534 ?-1535 ?) occupe une place de choix grâce à son usage original de l’esthétique de la farce comme véhicule de propagande évangélique. La pièce met en scène la conversion du personnage éponyme à la nouvelle foi sous la forme d’une guérison spectaculaire due au sermon de la Chambrière, personnage-type féminin connu de la farce conjugale, y compris la tradition narrative. Si le discours thérapeutique de l’humble servante vise à tourner en ridicule tout à la fois le savoir populaire incarné par la Femme et la profession médicale représentée par le Medecin, faisant écho au théâtre protestant satirique de la première moitié du xvi e siècle,elle donne également lieu à un débat sur les causes, le mécanisme psychique, ainsi que les implications sociales et religieuses de la conversion, transformation radicale de l’individu dont la célèbre conversiosubita de Jean Calvin permettra par la suite de mesurer toute l’ampleur. C’est en développant le rôle rhétorique et dramatique de la Chambrière, qu’elle représente dans la double posture de servante des hommes et de Dieu, que Marguerite parvient à mettre la farce au service de cette enquête.
Replacer la farce dans les festivités joyeuses du XVI e siècle. Le cas des Soupiers de Monville
Authors: Bichüe Jérémie , Lavéant Katell
Published: December 2021

Cet article porte sur la farce des Soupiers de Monville , qui figure dans le ms. f. fr. 24341 de la BnF, recueil dit « La Vallière » ou « de Rouen ». L’intérêt de cette pièce méconnue ne tient pas à son intrigue fort simple (la punition de trois quidams médisants), mais au rapport complexe qui s’établit, dans cette fiction judiciaire, entre la scène, la salle et l’actualité rouennaise du milieu du xvi e siècle. L’approche retenue est à la fois historique, performative et poétique. En effet, l’analyse du cadre performanciel des Soupiers de Monville nous aide à mieux comprendre le rôle de la compagnie joyeuse des Conards de Rouen à la fin des années 1540, mais elle éclaire aussi la fonction médiatrice de la représentation farcesque au xvi e siècle, ainsi que ses liens complexes vis-à-vis de la satire et de l’écriture polémique.
Le télétravail, frein à la représentation et à l’action collective en entreprise ?
Authors: Haute Tristan , Noûs Camille
Published: December 2021

Cet article interroge l’impact du télétravail sur la participation des salariés à la représentation et à l’action collective en entreprise. En mobilisant les données de l’enquête reponse 2017 (Relations professionnelles et négociation d’entreprise), nous montrons que le télétravail ne semble pas constituer en soi un frein à la participation. Les différences de participation observées sont en réalité liées au profil spécifique des télétravailleurs (moins précaires et appartenant aux couches supérieures du salariat). Les télétravailleurs occasionnels ne sont ainsi pas significativement moins participants que les autres salariés, y compris lorsqu’on se limite aux cadres, catégorie au sein de laquelle le télétravail est le plus répandu.
Jurisprudence France Télécom : du respect impératif de la dignité humaine au travail
Authors: Mazza Christelle
Published: December 2021

Près de vingt ans après l’introduction dans le droit français de la notion de harcèlement moral au travail, le tribunal judiciaire de Paris a rendu une décision retentissante en reconnaissant le principe d’un harcèlement systémique, au-delà de la définition classique des agissements répétés directs et interpersonnels, à travers une démonstration brillante et de haute pédagogie. Les développements relatifs à la définition de victime y sont tout aussi essentiels. Mais cette décision va bien au-delà de ce parachèvement jurisprudentiel en consacrant un véritable droit à la dignité humaine au travail, quelle que soit l’évolution de l’environnement économique. Derrière l’écran de la personne morale de droit privé plane l’ombre de l’État employeur et régulateur : un rappel nécessaire à nos fondements démocratiques.
Du service public au harcèlement moral, ou comment une politique d’entreprise peut devenir un délit

Après dix années de procédure, le travail de trois juges d’instruction et deux mois et demi d’audience, comment les juges de la 31 e chambre correctionnelle du tribunal judiciaire de Paris ont-ils raisonné pour prononcer des condamnations pour harcèlement moral à raison d’une politique d’entreprise ? Se pose ici la question de la définition du harcèlement moral institutionnel et sa distinction avec le pouvoir de direction. Au-delà de cette frontière, quels sont les faits constitutifs d’un harcèlement et comment définir les conditions de travail susceptibles d’être dégradées par un harcèlement moral ? L’intention est-elle une condition sine qua non à la condamnation et la personne morale est-elle un sujet de droit pénal ?
Does digital finance benefit the income of rural residents? A case study on China
Authors: Li Tinghui ,   School of Economics and Statistics, Guangzhou University, Guangzhou 510006, China, Ma Jiehua
Published: December 2021

Rural residents' income is one of the core issues of rural economic development, and digital financial inclusion is one of the important influencing factors of rural residents' income. Especially under the background of the implementation of digital financial technology, the relationship between the two has become more complex. Based on the panel data set of 1624 counties in Chinese mainland in the past 2014–2019 years, the paper uses panel regression models to study the impact of digital financial inclusion on rural residents' income. Further, by analyzing the industrial structure, education level and financial development level, the following conclusions are drawn. First, digital financial inclusion significantly promotes the increase of rural residents' income, but there are differences in regional level and different quantiles of rural residents' income. At the regional level, the promotion of control effect at the provincial level is stronger than that at the county level; in different quantiles of residents' income, with the increase of residents' income quantile, the promoting effect is gradually enhanced. Second, the heterogeneous impact of digital financial inclusion on rural residents' income is reflected in three aspects: regional development, education level and financial development level. Third, industrial structure, education level and financial development level will enhance the promotion effect of digital financial inclusion on rural residents' income, but there are significant differences in the intensity of the regulatory effect of the three variables.

From drill-and-practice assistants to digital tutors and coaches, Conversational learning offers a variety of new and extensive options to support individuals through the learning process and to push the boundaries of classroom-based learning. However, Conversational Learning applications that go beyond simple question-and-answer dialogs are still rare. “Pit in the Warehouse” takes a new stance to Conversational Learning: by combining an dialogical escape room challenge with an interactive fiction approach and compelling storytelling, it creates an engaging and low-threshold type of game-based learning.
Case Study: Rapid Training of Community Health Workers Using Enskill®
Authors: Johnson W. Lewis
Published: December 2021

The COVID-19 pandemic caused many workers to lose their jobs, and also resulted in rapid surges in demand for workers with particular skills. In public health there was suddenly a huge demand for community health workers to conduct contact tracing, vaccination, and community outreach. To address this need, our team undertook the challenge of creating an online course that trains workers for community health work in half the time of typical training programs. It utilizes the Enskill® learning platform, which uses AI technology to create simulated scenarios in which trainees practice skills with avatars acting as simulated patients. Fifty-seven training participants without college degrees were recruited for the program from the Hampton Roads region, in collaboration with the Hampton Roads Workforce Council. The first cohorts of trainees were able to complete the training successfully in just eight weeks, and are now being placed in public health and healthcare positions. The approach also shows promise for upskilling existing employees to address skill gaps. The Enskill training program is a competitor in the XPRIZE Foundation’s Rapid Reskilling competition, to quickly reskill under-resourced workers for the digital revolution.

Hybrid online delivery, which is also referred to as mixed-mode delivery, utilizes a combination of online content and traditional face-to-face methods which may benefit significantly from specific delivery adaptations for undergraduate engi-neering curricula. Herein, a novel eight-step phased instructional flow with several targeted adaptations is used to accommodate the mixed-mode delivery of STEM curricula is evaluated with a longitudinal study of students afforded these adapta-tions versus those without them. This STEM Blended Delivery Protocol (STEM-BDP) emphasizes scaffolding of analytical procedures along with hands-on prob-lem solving throughout online and face-to-face components equally. Two high enrollment course case studies utilizing STEM-BDP are examined herein, includ-ing an Electrical and Computer Engineering required core undergraduate course and a Mechanical and Aerospace Engineering undergraduate course. The details of the STEM-BDP delivery strategies, learning activities, and student perceptions surveys are presented. Student-resolution longitudinal analysis within a controlled study using blinded evaluation indicates that over a five-year period, failure rates have decreased by 63% among students undergoing STEM-BDP while control and alternatives have not demonstrated similar improvements within the same degree programs.

Given increasing enrollments within STEM curricula, it is sought to overcome challenges of conventional lecture-only delivery in high-enrollment courses.

Published: December 2021

Our motivation in this paper is to predict student Engagement (E), Behavior (B), Personality (P) and Performance (P) via designing a Tracking Student Perfor-mance Tool (TSPT) that obtained data directly from Moodle logs of any selected courses. The proposed tool follows the predictive EBP model that focuses mainly on student's EBP and Performance where the instructor could use it to monitor the overall performance of his/her students during the course. The results of test-ing the tool show that the developed tool gives the same as manual results analy-sis. Analyzing Moodle log of any course using such a tool is supposed to help with the implementation of similar courses and helpful for the instructor in re-designing it in a way that is more beneficial to the students. This paper sheds light on the importance of studying student's EBPP and provides interesting possibili-ties for improving student performance with a specific focus on designing online learning environments or contexts.

Authors: Wang Ting
Published: December 2021

With the continuous expansion of economic globalization, English, as the official language in the world, has a high popularity. It can be related to a better development in the future. Meanwhile, with the continuous progress of technology in modern society, multimedia online teaching has become the main means in colleges and universities, which especially brings great changes to foreign language teaching. However, foreign language teaching is facing many difficulties such as large number of contents, less lessons and low participation of students in class. Therefore, the reform of college foreign language teaching is imperative. Based on blended collaborative teaching mode, the paper has designed a “Three Classes” composed of “Communication Class”, “Famous Teacher Class” and “Elite Online Class”. Teaching process has been designed according to the cognitive process of “Previewing before class, consolidating in class and expanding after class”. In addition, recommendation algorithm has been used to collect data on four dimensions, namely, involvement in foreign language learning, content completion of foreign language learning, interaction in foreign language learning and effectiveness of foreign language learning. A performance evaluation system for foreign language learning supported by big data has been established. The results of teaching practice have proved that the blended collaborative teaching mode implemented in the study can be integrated into the whole teaching process through intelligent data analysis, information sharing and technology application, improving teaching quality, enhancing the interaction between teachers and students, which is worthy of promotion and application.

Critical thinking skills are one of essential employability skills for graduates when entering the workforce. The lack of critical thinking skills among Malaysian graduates is a concern as these skills are important for success in the 21st century. Therefore, this paper aims to study the effects of online reciprocal peer tutoring (RPT) through Facebook discussion on students’ critical thinking. In this study, the online RPT approach in Facebook was used to nurture students to think critically. In RPT, the tutor role is switched between participants in each task, giving equal opportunities to all learners to benefit from the tutor and tutee role. This approach was integrated into their learning for 4 weeks to increase students' critical thinking. During the learning process, they need to involve in 4 critical thinking tasks based on Bloom's taxonomy. 29 undergraduate students from the school of education, Faculty of Social Sciences and Humanities at Universiti Teknologi Malaysia completed the validated instrument, Watson-Glaser Critical Thinking Appraisal test (inference, assumption, deduction, interpretation, evaluation arguments) before and after the treatment. The findings show that it is significantly different in making inference (Z=-3.85, p=.000

Deeper Self-Directed Learning for the 21st Century and Beyond
Authors: van Zyl Sukie , Mentz Elsa
Published: December 2021

In this chapter, self-directed learning (SDL) and the competency to transfer knowledge between different contexts are positioned as essential competencies for the 21st century. Being able to transfer knowledge, especially between different contexts, has increasingly been indicated as essential competency for the 21st century. Transfer of knowledge and skills has however been neglected in SDL research. It is therefore argued that students should be deeper self-directed learners, who can take responsibility for their learning to obtain transferable competencies. Learners should be able to apply their knowledge and SDL skills to new and unknown situations in order to succeed in the 21st century and beyond. Social constructivist theory is suggested as theoretical basis for deeper self-directed learning (DSDL). In this chapter, the concept of DSDL will be defined, and various competencies associated with DSDL will be discussed. Finally, suggestions will be made to develop DSDL in education.
