Magnetospheric Multiscale Observations of Foreshock Transients at Their Very Early Stage
Authors: Liu Terry Z. , An Xin , Zhang Hui , Turner Drew
Published: October 2020

Foreshock transients are ion kinetic structures in the ion foreshock. Due to their dynamic pressure perturbations, they can disturb the bow shock and magnetosphere–ionosphere system. They can also accelerate particles contributing to shock acceleration. However, it is still unclear how exactly they form. Recent particle-in-cell simulations point out the important role of the electric field and Hall current in the formation process. To further examine this, we use data from the Magnetospheric Multiscale (MMS) mission to apply case studies on two small (1000–2000 km) foreshock transient events that just started to form. In event 1 where MMS was in a tetrahedral formation, we show that the current density configuration, which determined the magnetic field profile, was mainly driven by Hall currents generated by demagnetized foreshock ions. The resulting time variation of the magnetic field induced an electric field that drove cold plasma moving outward with magnetic field lines. In event 2 where MMS was in a string-of-pearls formation, we analyze the evolution of field and plasma parameters. We show that the magnetic flux and mass flux were transported outward from the core, resulting in the steepening of the boundary. The steepened boundary, which trapped more foreshock ions and caused stronger demagnetization of foreshock ions, nonlinearly further enhanced the Hall current. Based on our observations, we propose a physical formation process wherein the positive feedback of foreshock ions on the varying magnetic field caused by the foreshock ion Hall current enables an “instability” and the growth of the structure.
Disk Illumination and Jet Variability of the Herbig Ae Star HD 163296 Using Multi-epoch HST/STIS Optical, Near-IR, and Radio Imagery and Spectroscopy

Published: October 2020

We present two new epochs of Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph coronagraphic imaging, along with multi-epoch optical, near-IR, and radio monitoring, of the HD 163296 system. We find that ansae features identified in earlier-epoch HST imagery are a fourth ring that resides at a semimajor axis distance of 3.″25 (330 au). We determine that the scale height of the dust is 64 au at a radial distance of 330 au. We observe surface brightness variations in the fourth ring on <3 month timescales, including large-scale, azimuthally asymmetric changes. This variability resembles earlier studies of the innermost disk ring (0.″66, 67 au), suggesting a common origin. We find no evidence for the ejection of new HH knots predicted to occur in 2018. Moreover, our nondetection of older HH knots indicates that the knots could be experiencing less shock heating. We also detect one clear dipper event in our optical light curve from 2018. Using the timescale and spatial extent of the disk illumination changes we observe, we estimate that the source of this shadowing resides within 0.5 au from the star, must extend at least 0.08 au above the midplane of the disk, and has an azimuthal extent of 0.26 au. We estimate that the source of the dipper event reaches a scale height of 0.37 au above the midplane at 0.41 au and has an azimuthal extent of 0.3 au. We suggest that these similarities could indicate that the same (or similar) mechanisms are responsible for producing both dippers and variable ring illumination in the system.

Extreme-ultraviolet and X-ray emission from stellar coronae drives mass loss from exoplanet atmospheres, and ultraviolet emission from stellar chromospheres drives photochemistry in exoplanet atmospheres. Comparisons of the spectral energy distributions of host stars are, therefore, essential for understanding the evolution and habitability of exoplanets. The large number of stars observed with the MUSCLES, Mega-MUSCLES, and other recent Hubble Space Telescope observing programs has provided for the first time a large sample (79 stars) of reconstructed Lyα fluxes that we compare with X-ray fluxes to identify significant patterns in the relative emission from these two atmospheric regions as a function of stellar age and effective temperature. We find that as stars age on the main sequence, the emissions from their chromospheres and coronae follow a pattern in response to the amount of magnetic heating in these atmospheric layers. A single trend-line slope describes the pattern of X-ray versus Lyα emission for G and K dwarfs, but the different trend lines for M dwarf stars show that the Lyα fluxes of M stars are significantly smaller than those of warmer stars with the same X-ray flux. The X-ray and Lyα luminosities divided by the stellar bolometric luminosities show different patterns depending on stellar age. The L(Lyα)/L(bol) ratios increase smoothly to cooler stars of all ages, but the L(X)/L(bol) ratios show different trends. For older stars, the increase in coronal emission with decreasing

is much steeper than that of chromospheric emission. We suggest a fundamental link between atmospheric properties and trend lines relating coronal and chromospheric heating,
Spectral Variability of the Blazar 3C 279 in the Optical to X-Ray Band during 2009–2018
Authors: Yoo Sungmin , An Hongjun
Published: October 2020

We report on the spectral variability of the blazar 3C 279 in the optical to X-ray band between MJD 55100 and 58400 during which long-term radio variability was observed. We construct light curves and band spectra in each of the optical (2 × 1014–1.5 × 1015 Hz) and X-ray (0.3–10 keV) bands, measure the spectral parameters (flux F and spectral index α), and investigate the correlation between F and α within and across the bands. We find that the correlation of the optical properties dramatically change after ∼MJD 55500 and the light curves show more frequent activity after ∼MJD 57700. We therefore divide the time interval into three “states” based on the correlation properties and source activity in the light curves, and analyze each of the three states separately. We find various correlations between the spectral parameters in the states and an intriguing 65 day delay of the optical emission with respect to the X-ray one in state 2 (MJD 55500–57700). We attempt to explain these findings using a one-zone synchro-Compton emission scenario.
NICER Observation of the Temporal and Spectral Evolution of Swift J1818.0−1607: A Missing Link between Magnetars and Rotation-powered Pulsars

Published: October 2020

We report on the hard X-ray burst and the first ∼100 days of NICER monitoring of the soft X-ray temporal and spectral evolution of the newly discovered magnetar Swift J1818.0−1607. The burst properties are typical of magnetars with a duration of T
90 = 10 ± 4 ms and a temperature of kT = 8.4 ± 0.7 keV. The 2–8 keV pulse shows a broad, single-peak profile with a pulse fraction increasing with time from 30% to 43%. The NICER observations reveal strong timing noise with

varying erratically by a factor of 10, with an average long-term spin-down rate of

s−2, implying an equatorial surface magnetic field of 2.5 × 1014 G and a young characteristic age of ∼470 yr. We detect a large spin-up glitch at MJD 58928.56 followed by a candidate spin-down glitch at MJD 58934.81, with no accompanying flux enhancements. The persistent soft X-ray spectrum of Swift J1818.0−1607 can be modeled as an absorbed blackbody with a temperature of ∼1 keV. Its flux decayed by ∼60% while the modeled emitting area decreased by ∼30% over the NICER observing campaign. This decrease, coupled with the increase in the pulse fraction, points to a shrinking hot spot on the neutron star surface. Assuming a distance of 6.5 kpc, we measure a peak X-ray luminosity of 1.9 × 1035 erg s−1, lower than its spin-down luminosity of 7.2 × 1035 erg s−1. Its quiescent thermal luminosity is ≲1.7 × 1034 erg s−1, lower than those of canonical young magnetars. We conclude that Swift J1818.0−1607 is an important link between regular magnetars and high-magnetic-field, rotation-powered pulsars.
Waterworlds May Have Better Climate Buffering Capacities than Their Continental Counterparts
Authors: Hayworth Benjamin P. C. , Foley Bradford J.
Published: October 2020

The long-term habitability of a planet is often assumed to be controlled by its ability to cycle carbon between the solid planetary interior and atmosphere. This process allows the planet to respond to external forcings (i.e., changes in insolation, changes in volcanic outgassing rates, etc.) and regulate its surface temperature through negative feedbacks on atmospheric CO2 involved in silicate weathering. Continental weathering and seafloor weathering rates have different, non-linear dependencies on pCO2 and will respond differently to changes in external forcings. Because waterworlds (planets with only seafloor weathering) have a weaker pCO2 dependence than continental worlds (such as modern Earth), we find that waterworlds are better at resisting changes in surface temperature resulting from perturbations in insolation than their continental counterparts, and may be more habitable in this respect.
Discovery of Ground-state Absorption Line Polarization and Sub-Gauss Magnetic Field in the Post-AGB Binary System 89 Her
Authors: Zhang Heshou , Gangi Manuele , Leone Francesco , Taylor Andrew , Yan Huirong
Published: October 2020

We report the polarization of ground-state absorption lines from the post-asymptotic giant branch (post-AGB) binary star system 89 Herculis (89 Her). Two ground-state neutral iron lines are found to have counterintuitive high-amplitude polarizations and an unchanged polarization direction through the orbital period. This is contrary to the pattern of polarization of absorption lines from excited states, which are synchronized with the orbital phase due to optical pumping. This can be explained by magnetic realignment of the ground state, whereby the 3D mean magnetic field is unveiled from the degree and direction of the polarizations of the two iron lines. The field strength is also constrained to be ≲100 mG. Our result improves the accuracy by orders of magnitude compared to the previous 10 G upper limit set by non-detection of the Zeeman effect.
A comprehensive approach to the diagnosis and treatment of chronic coronary syndrome
Authors: Stoyanova Velina
Published: October 2020

Coronary artery disease (CAD) is a chronic progressive disease with social signiﬁ cance, result ofobstructive or non- obstructive atherosclerotic plaque accumulation in the epicardial arteries. CAD is one of the leading causes for deterioration in quality of life and cardiovascular mortality. CAD has dynamic character and its major clinical presentations are: acute coronary syndromes (STEMI, NSTEMI, UA) and chronic coronary syndromes. In this case report we present the treatment algorithm in patient with chronic coronary syndrome: from optimal medical therapy, through objective methods of examination leading to the decision for interventional treatment and the importance of regular follow-up.
Festuca drakensbergensis (Poaceae): A common new species in the F. caprina complex from the Drakensberg Mountain Centre of Floristic Endemism, southern Africa, with key and notes on taxa in the complex including the overlooked F. exaristata
Authors: Sylvester Steven P. , Soreng Robert J. , Sylvester Mitsy D. P. V. , Clark Vincent Ralph
Published: October 2020

We present taxonomic notes on the Festuca caprina complex from southern Africa that includes description and illustration of the new species F. drakensbergensis from the Drakensberg Mountain Centre of Floristic Endemism of South Africa and Lesotho. Festuca drakensbergensis can be differentiated from F. caprina s.l. by forming lax short tufts with extravaginally-branching tillers and lateral-tending cataphyllous shoots or rhizomes present, basal foliage reaching < ½ the length of the culms, with generally shorter leaves and shorter anthers, 0.8−1.6(−1.8) mm long. The species also differs from the overlooked species F. exaristata – currently known from two collections from Lesotho − by its fibrous basal sheaths, usually sharp, keel-like leaf blade midrib, drooping panicle with lightly to densely scabrous pendent panicle branches, longer lemmas, 4.5−5.8 mm long, with awns usually present, 0.5–3 mm long, ovary apices sparsely to densely hairy and anthers 0.8−1.6(−1.8) mm long. Taxonomic notes on the different taxa of the F. caprina complex in southern Africa are also provided, including images, key, and lectotypification of F. caprina var. curvula. This research adds a further two endemic species (F. drakensbergensis and F. exaristata) and two endemic varieties (F. caprina var. irrasa and F. caprina var. macra) to the Drakensberg Mountain Centre of Floristic Endemism.

Produire le pergraphe, intérêts et limites de l’approche générative
Authors: Micaëlli Jean-Pierre
Published: October 2020

Il est habituel, en contrôle de gestion, d’employer les tableaux de bord, les cartes mentales ou cognitives pour exprimer graphiquement les structures décrivant ou expliquant la performance étudiée, ou pergraphes. Toutefois, ces outils manquent d’abstraction. Cet article propose de recourir à SysML, un langage graphique de l’ingénierie, pour modéliser de façon plus rigoureuse les pergraphes et définir les patrons à partir desquels les générer. Si un contrôle de gestion fondé sur les graphes venait à se développer, l’approche proposée occuperait une intermédiaire entre la construction de pergraphes visuels et informels et la production de graphes analytiques.
Les psychologues dans le champ de la santé au travail
Authors: Grégoire Anne-Sylvie , Guidou Nadège
Published: October 2020

Cet article s’attache à montrer en quoi et comment les enjeux politiques et sociaux, qui traversent la profession de psychologue depuis toujours, se réactualisent dans le champ de la santé au travail. Il explicite comment ils viennent perturber l’activité des psychologues qui tend à prendre soin du travail et qui vise des changements significatifs dans le monde réel. Les auteures engagent la discussion sur la notion de santé mentale comme rouage de la productivité et sur les effets de développement ou de neutralisation de l’activité pluridisciplinaire selon les modalités de gestion ou de gouvernance des services de santé au travail. Face à la possible répétition du piège de la psychotechnique, confrontée à la sélection et l’adaptation des personnes au travail, construire des cadres pluridisciplinaires dialogiques et de connaissances sur les visées et pratiques en santé au travail apparait central.
Vivre et penser la mutation de l’institution : la pratique du psychologue
Authors: Nazir Karine , Papathanasiou Evgenia
Published: October 2020

Le psychologue clinicien en psychiatrie peut se trouver aujourd’hui confronté à des changements structuraux qui impactent sa pratique et le fonctionnement des équipes. Ce propos s’appuie sur l’expérience d’une mutation institutionnelle en cours : le soin institutionnel de longue durée se transformera progressivement en hébergement de type médico-social. Les effets du changement sont déjà présents ; des injonctions, de la confusion, de la déliaison gagnent du terrain. Nombreuses sont les questions qui apparaissent et qui agitent les professionnels des différents corps de métiers. Mais le dialogue s’avère complexe, et les équipes – psychologue inclus – se trouvent traversées par des mécanismes qui figent la pensée. Qu’est-ce qui permet alors de soutenir la réflexion à plusieurs ? Comment contribuer à l’émergence d’une pensée créative, dans ce contexte où la tâche primaire – organisateur principal d’une équipe – devient confuse ? Comment identifier les obstacles psychiques à l’œuvre afin de les dépasser ?
Psychologues de l’Éducation nationale : travailler aux limites
Authors: Goderniaux Ève , Sibony-Malpertu Yaelle , Maurin Souvignet Aurélie
Published: October 2020

Une recherche-action portant sur les liens famille-institutions a permis l’ouverture d’un volet spécifique consacré au rôle singulier joué par les psychologues de l’Éducation nationale ( p sy en ). Menée dans différents établissements scolaires du primaire et du secondaire, cette recherche approche, à travers l’évolution des missions dévolues aux p sy en , leur rôle de tiers concernant la mise en lien entre établissement scolaire, familles, élèves, professionnels et partenaires. Les propos recueillis lors d’entretiens individuels et des observations participantes ont mis en lumière certains paradoxes auxquels les p sy en peuvent être confrontés, notamment leur travail permanent autour des limites. Ainsi, le traitement accordé à la reconnaissance de la vie psychique dans les missions des p sy en, le choix de la présence ou de l’absence aux conseils de discipline et le recrutement par un collège d’une psychologue en libéral, suscitent analyses et interrogations.
Les patients à la merci d’arbitraires algorithmiques
Authors: de Kernier Nathalie
Published: October 2020

Depuis 2019, l’accès au professorat des universités françaises en psychologie est conditionné par la publication d’articles dans des revues de rangs q 1 ou q 2, selon le classement sci mago lié à la base de données scopus . En installant ces critères dépourvus de toute scientificité, le conseil national des universités a ignoré les recommandations internationales de prudence d’usage des indicateurs bibliométriques, n’étant en aucun cas conçus à des fins d’évaluation, de recrutement, de promotion ou de financement des chercheurs. S’ensuit une confusion entre une forme de visibilité des revues et la qualité supposée de leurs contenus. Cet article explore les conséquences de cette réforme sur les conceptions de la recherche, et dès lors aussi sur la formation des psychologues cliniciens et sur les soins prodigués aux usagers. Les patients seraient de plus en plus à la merci de ce que d’obscurs algorithmes donnent à voir des approches thérapeutiques, leur valeur étant définie de manière trompeuse.
Le soin sous mandat judiciaire auprès d’adolescents auteurs de violences… sexuelles. Variations autour du consentement
Authors: Roman Pascal
Published: October 2020

Le soin sous mandat judiciaire des adolescents auteurs de violences sexuelles bute sur la question centrale du consentement. On peut considérer que le soin sous mandat judiciaire confronte l’adolescent au paradoxe du consentement : en effet, celui-ci se trouve pris dans le même défaut de consentement à l’égard du soin que celui imposé à la victime au décours des violences. Cet article propose d’interroger le paradoxe du consentement, à partir de l’exploration des enjeux du con-sentir dans le soin psychothérapeutique : l’ouverture du con-sentir dans le lien thérapeutique constitue un levier déterminant pour dépasser les positions de clivage et de déni qui caractérisent la clinique des auteurs de violences sexuelles, et soutenir la relance du processus de subjectivation à l’adolescence.

Dix ans après la mort de Nathalie Zaltzman, nous revenons sur son ouvrage L’esprit du mal dans l’idée que les questions qu’elle soulève sont de plus en plus incontournables pour donner de la lisibilité à notre époque. Nous proposons de regarder la Shoah en tant que loupe posée sur l’humain, permettant la mise à jour du processus de déshumanisation. Notre objectif est de mieux comprendre le monde contemporain, en envisageant les tâches aporétiques de la Kulturarbeit que son héritage vivant nous assigne.
À l’ère de catastrophes planétaires, dépasser l’« egopsychanalyse » et l’« écologarchie »
Authors: Fognini Mireille
Published: October 2020

Sont brossées l’analyse et la nécessité de dépasser : d’une part, la difficulté dont a témoigné la communauté psychanalytique pour intégrer dans ses recherches le travail pionnier de Searles sur les liens entre processus inconscients et péril environnemental ; d’autre part, les excès doctrinaires de certaines groupalités œuvrant au nom des travaux de l’écologie scientifique sur la biodiversité de l’écosystème.
Enchaîné à des infinités : technologie, immédiateté et crise environnementale
Authors: Melmed Michael
Published: October 2020

L’article étudie le rapport entre le désir humain, la technologie et l’imagination en insistant sur : 1. la phénoménologie de ce rapport ; 2. ses ramifications ontologiques et écologiques. Partant des travaux de Bion et de Winnicott, il présente un cadre psychanalytique pour penser les attitudes qui contribuent à la crise climatique actuelle, en prêtant une attention particulière à l’effet problématique que la technologie a exercé sur notre sens du temps et de l’espace. L’auteur y soutient que les fantasmes d’omnipotence qui prédéterminent notre relation à la technologie, aux uns et aux autres ainsi qu’au monde non humain, nous ont enveloppés d’une sorte de réalité virtuelle qui détruit le sens d’une responsabilité majeure envers l’environnement.
Apprendre à « rêver » notre famille écobiotique : une éthique du futur
Authors: Magnenat Luc
Published: October 2020

Le fait que nous soyons la dernière génération à pouvoir agir pour limiter la catastrophe d’un réchauffement climatique non maîtrisable nous inscrit dans une configuration transgénérationnelle semblable à celle du mythe freudien de la horde primitive. La crise environnementale soulève une question hautement émotionnelle : serons-nous des Laïos et des Jocaste exposant notre descendance à la mort, ou serons-nous des Polybe et des Mérope tentant de ménager la possibilité d’un futur aux « générations Greta Thunberg » et à notre famille écosystémique biotique ? L’auteur fait l’hypothèse que la réponse à cette question dépendra de notre capacité à « rêver », selon le sens donné par Bion à cette notion, les forces émotionnelles inconscientes qui sous-tendent la crise environnementale, ainsi que les nouveaux paradigmes culturels émergents, pour mieux trouver notre place « d’enfants de la biosphère ».
Jouer avec l’environnement non humain

Le psychodrame analytique individuel offre un terrain de jeu propice aux identifications vers les éléments vivants et inertes de l’environnement. Le récit de quelques séances d’un adolescent nous montre combien les éléments non humains sont en réalité présents dans nos séances et se prêtent au jeu psychodramatique qui ne cesse de les transformer, de les rêver. Nous nous appuierons sur le concept de projection identificatoire dans sa version kleinienne, bionienne et postbionienne.
Ce qui peut naître entre un psychanalyste et son chien
Authors: Bolognini Stefano
Published: October 2020

L’auteur relate ici sa relation « atypique » avec les chiens : une peur ancienne mêlée d’attirance, puis le plaisir éprouvé dans un lien unique avec Lajos, son terrier Airedale . Cette expérience lui permet de découvrir – en tant qu’humain et psychanalyste – la richesse de l’interaction et de la communication de la rencontre inter-espèces. Cette expérience transformatrice et émouvante vient enrichir sa clinique psychanalytique par l’apprentissage de quelques « vérités fondamentales », telles l’honnêteté et une perception réaliste de ce qui se joue dans la relation. La révélation aussi que le chien représente la part instinctive de l’homme, celle qui perçoit en direct les contenus émotionnels. Cette spécificité du rapport chien-homme est appréhendée dans sa globalité grâce aux outils psychanalytiques.
Des épidémies à la pandémie, voyage dans la mémoire des hommes
Authors: Adam Elena
Published: October 2020

Avec la pandémie mondiale de la Covid-19, les angoisses liées aux menaces climatiques ont cédé à la peur et à l’effroi, faisant resurgir le spectre des grandes épidémies profondément gravées dans la mémoire phylogénétique de l’humanité. L’auteure cherche à en explorer les traces à travers la littérature par des témoignages d’un passé parfois confondu au présent, avec Axel Munthe, Alessandro Manzoni et Thomas Mann. Tout en interrogeant les ambiguïtés entre amour et haine de la nature.
La fonction mobilisatrice de la parole interprétative
Authors: Dufour Jacques
Published: October 2020

La fonction mobilisatrice de la parole interprétative est reliée par l’auteur à la naissance de la psychanalyse d’une scène primitive que Freud a vue entre Résistance et Transfert. Science de l’esprit utilisant ses trois dimensions, d’une expérience subjective, d’une pensée théorique et d’une parole interprétative, sa fécondité en work in progress sera sans limite, car toute limite d’une pensée théorique appelle une autre voie de pensée. Ainsi s’est ouvert un parcours en des chemins qui bifurquent, de Freud à Bion en passant par Melanie Klein, où de la limite de la parole symbolisante est née la parole transformatrice, puis de Bion à Grinberg en passant par Ogden, où de la limite de la parole transformatrice est né l’acte transformateur.
Situation d’urgence subjective lors des attentats (de Nice), trauma et création subjective
Authors: Jacob Alby Virginie
Published: October 2020

Par la présentation du cas de M. Hat, nous tenterons d’illustrer la façon dont la psychanalyse envisage le traitement du trauma et de l’urgence subjective. Ce traitement consistant dans une offre de parole faite au patient mais selon son temps logique et avec, au cœur de la démarche du don de la parole, l’idée que tout du traumatisme ne peut pas se dire, que c’est un « troumatisme ». Entre les deux temporalités – du temps du langage et du temps de la pulsion du corps parlant – se déploie le destin du sujet selon les trois temporalités logiques proposées par Lacan. Ainsi M. Hat témoignera de sa créativité dans sa façon singulière de donner une réponse au réel des attentats qui s’est imposé à lui.
Comprendre la méfiance vis-à-vis des vaccins : des biais de perception aux controverses
Authors: Ward Jeremy K. , Peretti-Watel Patrick
Published: October 2020

En France comme ailleurs, les autorités de santé sont aujourd’hui confrontées à une défiance inédite des populations à l’égard de la vaccination. Pour appréhender ce phénomène, les chercheurs et les experts de santé publique ont encore largement recours à l’approche traditionnelle du Public Understanding of Science ( pus ) . Cette approche défend un modèle déficitaire qui souligne les lacunes des profanes, qui seraient insuffisamment éduqués ; elle souligne aussi les multiples biais cognitifs qui affecteraient leurs perceptions ; enfin, elle diagnostique la montée d’un mouvement antiscience. Cet article dresse un état des lieux des connaissances relatives aux attitudes vis-à-vis des vaccins disponibles en France, en saisissant ce cas pour mettre la pus à l’épreuve. Il montre que la limite principale de cette approche réside dans son incapacité à intégrer la dimension sociale et culturelle de la cognition. Il esquisse, enfin, un modèle alternatif au pus qui place en son cœur la dimension culturelle de toute cognition et permet d’articuler les attitudes des individus avec l’émergence des controverses et les structures sociales.
Apollonios de Rhodes et le vocabulaire homérique : les verbes en -ιάω et les verbes en -άω à vocalisme ō
Authors: Morel Emmanuelle
Published: October 2020

Une partie importante du vocabulaire des Argonautiques est empruntée aux épopées homériques, ce qui n’implique pas qu’Apollonios l’emploie de la même manière qu’Homère. Cet article se propose d’étudier la manière dont Apollonios réutilise deux séries de verbes déjà présents dans le texte homérique, les verbes en -άω à vocalisme -ō- et les verbes en -ιάω, et de comparer leur emploi chez Apollonios avec celui que l’on trouve dans les épopées homériques. Ces deux séries de verbes sont considérées comme caractéristiques de la langue épique archaïque. Les verbes en -ιάω, et en particulier les formes à diectasis, sont très présentes à la fois chez Homère et chez Apollonios en raison de leur commodité métrique. Les verbes en -άω à -ō- radical, qui ne se trouvent guère en dehors de la langue poétique, appartiennent à une série qui déjà à l’époque archaïque est très peu productive et qui l’est encore moins par la suite, contrairement à celle des verbes en -ιάω, toujours productive à l’époque hellénistique. Ces deux séries sont bien représentées dans l’épopée d’Apollonios, d’une part parce qu’il réutilise largement le vocabulaire homérique et d’autre part parce qu’il emploie de nouveaux verbes appartenant à ces catégories. Il s’agira alors de comparer l’utilisation de chacun de ces verbes dans les Argonautiques avec son emploi dans le texte homérique, notamment sous les angles morphologique, sémantique et syntaxique. Si certains emplois des Argonautiques sont très proches de ce que l’on peut trouver chez Homère, parfois même sur le mode de la référence, d’autres s’en écartent notamment sur le plan syntaxique et il s’agira de déterminer pourquoi. Enfin, nous étudierons certains verbes nouveaux relevant de ces deux catégories.
Comparaison comme estrangement : Machiavel, les anciens, les modernes, les sauvages
Authors: Biasiori Lucio
Published: October 2020

Machiavel a été toujours considéré comme un classique de la pensée politique européenne. Cet article, tout en abordant la question humaniste de l’imitation du monde ancien, contribue à étudier l’émergence d’une discussion relative au nouveau monde à travers une première comparaison polémique entre l’Europe et les terres nouvellement découvertes. La question qui s’impose est de savoir si cette rencontre s’est limitée à une adaptation du nouveau aux schèmes culturels européens et en quelle mesure la réflexion sur Machiavel a été transformée par le contact avec le nouveau monde.

PURPOSE:

The purpose of this study was to evaluate whether papilledema severity is associated with specific demographic or clinical factors in patients with idiopathic intracranial hypertension (IIH).

MATERIALS AND METHODS:

A retrospective cohort study of consecutive IIH patients seen at one tertiary care institution between 1989 and March 31, 2017 was performed. IIH patients were classified as mild (Frisén Grade 1 or 2) or severe (Frisén Grade 4 or 5) based on grading of fundus photographs obtained at first presentation. Demographic and clinical variables including age, body mass index (BMI), gender, visual acuity, Humphrey visual field mean deviation, and cerebrospinal fluid (CSF) opening pressure were extracted from patient medical records for statistical analyses.

RESULTS:

A total of 239 patients were included in the study: 152 with mild papilledema and 87 with severe papilledema. There was no difference in age, race, BMI, or male gender between the mild and severe papilledema groups. CSF opening pressure was significantly higher in the severe papilledema group (41.89 cm of water vs. 33.69, 95% confidence interval [CI]: −10.79–−5.62, P < 0.0001). There was a significant difference in the Humphrey mean deviation (−6.38 dB compared to − 3.25 dB, 95% CI: −4.82–−1.44 dB, P < 0.001) and average logarithm of the minimum angle of resolution visual acuity at final follow-up (0.21 vs. 0.045, 95% CI: −0.299–−0.040, P = 0.01).

CONCLUSION:

Age, race, sex, and BMI were similar in IIH patients with mild versus severe papilledema, emphasizing the importance of a dilated fundus examination to reliably stratify patients. Patients with severe papilledema are at higher risk of visual acuity and visual field loss at final follow-up.
Determinants of job seekers to select recruitment agency for new job vacancies
Authors: Binh Phan Xuan , Ha Nguyen Minh
Published: October 2020

The most important determinant of organizational effectiveness is the ability to attract, hire, and develop capable talent. The ability to attract and retain superior employees can lead to sustained competitive advantage for organizations. This is difficult due to the shrinking availability of qualified labor. The use of recruitment agency (RA) or employment agency allows human resource departments to target and identify quality candidates with more efficiency. RA, kind of consultancy, is normally understood as third party recruiter that finds jobs for people seeking them and finds people to fill particular jobs3 . Some RA focus their efforts on executive, managerial, and professional positions (white and yellow collar workers). These firms are split into two groups: (1) contingency firms that charge a fee only after a candidate has been hired by a client company and (2) retainer firms that charge a client a set fee whether or not the contracted search is successful. Most of RA in Vietnam apply contingency basis. Majority of foreign and big local companies use RA as one of the key recruitment sources to attract middle to senior level employees despite there is maybe higher expenses of this source than using other recruitment sources in some extents below: • The job vacancy is top confidential and recruiter cannot launch the public recruitment • The vacancy requires very short time to fill • The limited staffing resources of recruiting department or • The limited candidate pool in some industries or function which may cause very long time to fill the vacancy or to find out the right candidate.
Adopting Japanese lean practices into the Vietnamese context: Slow and steady is the sure way to go
Authors: Reynold James , Anh Dinh Nhu
Published: October 2020

In tandem with Vietnam’s growing economic activity in recent years is the observable trend of Vietnamese firms across various sectors increasingly adopting Japanese lean management principles and practices. Evidencing this is the ever increasing extent of lean related activity in the form of lean management and production workshops, seminars, and training and consulting activity across the nation, with the year 2013 –christened by some- as the ‘year of the lean concepts’. Whilst lean has its advantages, and with a coterie of scholars advocating that lean is an epoch making model, transferable like a technical object from any one geographic location into another and is devoid of context, there are others who advocate that the efficacy of lean –when transplanted outside of Japan- is contingent upon several contextual factors within the host nation. The extant literature on lean and on institutional transplantation reveals several cases wherein

attempts to transplant the lean model into non-Japanese socio-cultural climes have resulted in outcomes ranging from minimal success to failure. This paper highlights a few contextual aspects that merit consideration by Vietnamese industries adopting lean practices, and in so doing, purports to tone down any unrealistic perceptions that managers and industrialists may harbor, about lean being a silver bullet that can overnight transform their firms into star performers.
Implementation of balanced scorecard in Vietnamese enteprises
Authors: Anh Trinh Thuy
Published: October 2020

Balanced scorecard is a highly effective method for performance measurement and strategic management in organizations and enterprises. The number of companies applying this method in Vietnam currently is not very high. For this reason, this paper aims to determine key factors for success when implementing balanced scorecard in Vietnamese enterprises. Then, it assesses the possibility for applying the method in companies who are planning to apply it. The data was collected from a survey of 6 companies who have applied balanced scorecard successfully and 19 companies who want to apply it. The data analysis result from the 6companies who have had success with the balanced scorecard shows four major success factors, including balanced scorecard usefulness, balanced scorecard design, company human resource capacity, and balanced scorecard implementation process. Then, these factors were applied into 19 companies who have interest in implement the balanced scorecard to evaluate the ability to apply balanced scorecard. The result show that senior leaders’ point of views, strategy planning and execution, performance assessment, human resource capacity, and operation management of the company could affect to balanced scorecard implementation. Therefore, business leaders need to focus on these factors in order to successfully implement balanced scorecard in Vietnamese enterprises. Qualitative analysis were applied in this study.

Published: October 2020

Globalization and regionalization have influenced Vietnam labor market more robustly, especially since the establishment of the ASEAN Economic Community in 2015. Hence, preparing for students for a dynamic workforce becomes critical. This paper examines the attributes of student career preparation and their relationships with the willingness to work in ASEAN. We used the Structural Equation Model to test the research model with the data collection of 317 university students in Ho Chi Minh City, Vietnam. The empirical result indicated that regional economic integration awareness and academic experiences have remarkably influenced on career preparation, which also had a strong impact on the willingness of students to accept working overseas. Moreover, the students’ willingness to accept the international job was affected by the awareness of linguistic skills influence and cultural awareness. Specifically, Vietnamese students have been reluctant to work in ASEAN after graduation despite the influence of globalization and regionalization. Besides, we also conducted 10 in-depth interviews to highlight our quantitative results and achieve a further understanding of the hidden causes. Thus, the paper discussed critical recommendations to improve student career preparation and confidence.

Authors: Quy Vo Thi , Nguyen Le Thi Minh
Published: October 2020

This research investigates the effects of working capital management through cash conversion cycle and its components (average receivable days - ARD, average inventory days – AID, and average payable days - APD), along with the effects of the working capital management policies on firm performance and firm value in the fisheries industry. Generalized Method of Moment (GMM) was applied with the data collected from 21 fisheries companies listed on Vietnam's stock market in the period 2008 -2012. The research found that the cash conversion cycle, average receivable days, average inventory days, and average payable days have a negative impact on firm performance (ROA) and firm value (Tobin'Q). The research results also showed that aggressive working capital policy has a negative impact, but the conservative working capital policy has a positive impact on firm performance and firm value of fisheries selected companies.

Authors: Sankhi Sabina , Nirmal Raj Marasine
Published: October 2020

Background: The COVID-19 among humans is spreading heavily and is largely impacting the mental health of the general population, students, and health care workers worldwide. Hence, this review aims to summarize the literatures addressing the impact of the COVID-19 pandemic on the mental health of the general population, students, and health care workers.

Methods: Published articles concerning mental health of the general population, students, and health care workers related to the COVID-19 outbreak have been considered and reviewed.

Results and discussion: Mental health symptoms of stress, anxiety, and depression are common psychological reactions to the COVID-19 pandemic in the general population, students, and health care workers. This collectively influences daily behavior, economy, prevention strategies and decision making from policy makers and health organizations, weakening the strategies of COVID-19 control leading to more morbidity and mental health needs at the global level.

Conclusion: There is a need for more evidence-based research from other affected countries, particularly in vulnerable populations such as children and adolescents, people of lower socioeconomic status, and those residing in rural areas, so that valid strategies can be developed and COVID-19 and outbreaks of similar types in the near future can be prevented
