The Impacts of Spatial Interaction on Agricultural Productivity and Average Income: A Case of Vietnam
Authors: Cong Bac Truong , Van Tran Quang 
Published: July 2021

Agricultural productivity plays a crucial role in sustainable development while income is one of the most critical indicators that manifest the living standards; therefore, both of these aspects have attracted much attention from the national level to the provincial level. Yet, for various reasons, the importance of regional linkages, especially spatial interaction in the analysis of agricultural productivity and the average income, is not recognized and thus ignored in economic policies. Taking Vietnam as the study area, this paper examines the impact of spatial interaction between metropolises and provinces on agricultural productivity and income per capita of provinces. In order to evaluate the impacts, this paper uses a gravity model to estimate the spatial interaction then panel data analysis is employed to interpret the influences. The data used in this study is collected from the General Statistics Office of Vietnam in the period from 2015-2018. The results show a positive correlation between spatial interaction between metropolis and provinces to provincial change, including agricultural productivity and average income. As such, stronger linkages with metropolises through improving transportation systems could enhance agricultural productivity and income in the province.
The Age–Metallicity–Specific Orbital Energy Relation for the Milky Way’s Globular Cluster System Confirms the Importance of Accretion for Its Formation
Authors: Woody Turner , Schlaufman Kevin C. 
Published: July 2021

Abstract
Globular clusters can form inside their host galaxies at high redshift when gas densities are higher and gas-rich mergers are common. They can also form inside lower-mass galaxies that have since been accreted and tidally disrupted, leaving their globular cluster complement bound to higher-mass halos. We argue that the age–metallicity–specific orbital energy relation in a galaxy’s globular cluster system can be used to identify its origin. Gas-rich mergers should produce tightly bound systems in which metal-rich clusters are younger than metal-poor clusters. Globular clusters formed in massive disks and then scattered into a halo should have no relationship between age and specific orbital energy. Accreted globular clusters should produce weakly bound systems in which age and metallicity are correlated with eachother but inversely correlated with specific orbital energy. We use precise relative ages, self-consistent metallicities, and space-based proper motion-informed orbits to show that the Milky Way’s metal-poor globular cluster system lies in a plane in age–metallicity–specific orbital energy space. We find that relatively young or metal-poor globular clusters are weakly bound to the Milky Way, while relatively old or metal-rich globular clusters are tightly bound to the Galaxy. While metal-rich globular clusters may be formed either in situ or ex situ, our results suggest that metal-poor clusters are formed outside of the Milky Way in now-disrupted dwarf galaxies. We predict that this relationship between age, metallicity, and specific orbital energy in a L* galaxy’s globular cluster system is a natural outcome of galaxy formation in a ΛCDM universe.

Published: July 2021

Abstract
The results of speckle interferometric observations at the 4.1 m Southern Astrophysical Research Telescope in 2020, as well as earlier unpublished data, are given, totaling 1735 measurements of 1288 resolved pairs and nonresolutions of 1177 targets. We resolved for the first time 59 new pairs or subsystems in known binaries, mostly among nearby dwarf stars. This work continues our long-term speckle program. Its main goal is to monitor orbital motion of close binaries, including members of high-order hierarchies and Hipparcos pairs in the solar neighborhood. We also report observations of 892 members of young moving groups and associations, where we resolved 103 new pairs.
Variations in Finite-difference Potential Fields

Published: July 2021

Abstract
The potential field (PF) solution of the solar corona is a vital modeling tool for a wide range of applications, including minimum energy estimates, coronal magnetic field modeling, and empirical solar wind solutions. Given its popularity, it is important to understand how choices made in computing a PF may influence key properties of the solution. Here we study PF solutions for the global coronal magnetic field on 2012 June 13, computed with our high-performance finite-difference code POT3D. Solutions are analyzed for their global properties and locally around NOAA AR 11504, using the net open flux, open-field boundaries, total magnetic energy, and magnetic structure as metrics. We explore how PF solutions depend on (1) the data source, type, and processing of the inner boundary conditions; (2) the choice of the outer boundary condition height and type; and (3) the numerical resolution and spatial scale of information at the lower boundary. We discuss the various qualitative and quantitative differences that naturally arise by using different maps as input, and we illustrate how coronal morphology and open flux depend most strongly on the outer boundary condition. We also show how large-scale morphologies and the open magnetic flux are remarkably insensitive to model resolution, while the surface mapping and embedded magnetic complexity vary considerably. This establishes important context for past, current, and future applications of the PF for coronal and solar wind modeling.
Spatially Resolved RGS Analysis of Kepler’s Supernova Remnant

Published: July 2021

Abstract
The distribution and kinematics of the circumstellar medium (CSM) around a supernova remnant (SNR) tell us useful information about the explosion of its natal supernova (SN). Kepler's SNR, the remnant of SN 1604, is widely regarded to be of Type Ia origin. Its shock is moving through a dense, asymmetric CSM. The presence of this dense gas suggests that its parent progenitor system consisted of a white dwarf and an asymptotic giant branch (AGB) star. In this paper, we analyze a new and long observation with the reflection grating spectrometers on board the XMM-Newton satellite, spatially resolving the remnant emission in the cross-dispersion direction. We find that the CSM component is blueshifted with velocities in the general range 0–500 km s−1. We also derive information on the central bar structure and find that the northwest half is blueshifted, while the southeast half is redshifted. Our result is consistent with a picture proposed by previous studies, in which a “runaway” AGB star moved to the north-northwest and toward us in the line of sight, although it is acceptable for both single- and core-degenerate scenarios for the progenitor system.
Probing Microporous ASW with Near-infrared Spectroscopy: Implications for JWST's NIRSpec

Published: July 2021

Abstract
The presence of porous amorphous solid water (ASW) in interstellar ice mantles has long been suspected but, to date, has not been identified. With the upcoming launch of the James Webb Space Telescope (JWST), future detections of porous ASW seem promising. To this end, we investigated the near-infrared spectra of ASW to confirm that two features that have been seen sporadically in literature and have either not been identified or only tentatively identified were indeed due to dangling bond (DB) absorption bands. These bands may provide an additional way to identify porous ASW with remote sensing spectroscopy. Our systematic study tested the thermal stability of these features and their spectral shifts during gas adsorption. We correlated these changes to what we observed in the well-studied fundamental DB absorptions at 3720 and 3696 cm−1. We find excellent agreement between the behavior of the fundamental DB absorption bands with those centered at 5326 and 7235 cm−1, as well as a shoulder located at 7285 cm−1, confirming that all these features are due to DBs present in porous ASW. We estimate that these weaker DB absorptions should be identifiable after 4–5 hr of observation time with JWST’s NIRSpec instrument. These new features may not only prove useful in future observational campaigns in search of porous ASW but also may serve as a powerful way to indirectly detect weakly absorbing species that challenge the ability of remote sensing spectroscopy.
Formation of Solar Quiescent Coronal Loops through Magnetic Reconnection in an Emerging Active Region

Abstract
Coronal loops are the building blocks of solar active regions. However, their formation mechanism remains poorly understood. Here we present direct observational evidence for the formation of coronal loops through magnetic reconnection as new magnetic fluxes emerge into the solar atmosphere. Extreme-ultraviolet observations by the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO) clearly show the newly formed loops following magnetic reconnection within a plasma sheet. Formation of the loops is also seen in the Hα line-core images taken by the New Vacuum Solar Telescope. Observations from the Helioseismic and Magnetic Imager on board SDO show that a positive-polarity flux concentration moves toward a negative-polarity one with a speed of ∼0.4 km s−1 before the formation of coronal loops. During the loop formation process, we found signatures of flux cancellation and subsequent enhancement of the transverse field between the two polarities. The three-dimensional magnetic field structure reconstructed through a magnetohydrostatic model shows field lines consistent with the loops in AIA images. Numerous bright blobs with an average width of 1.37 Mm appear intermittently in the plasma sheet and move upward with a projected velocity of ∼114 km s−1. The temperature, emission measure, and density of these blobs are about 3 MK, 2.0 × 1028 cm−5, and 1.2 × 1010 cm−3, respectively. A power spectral analysis of these blobs indicates that the observed reconnection is likely not dominated by a turbulent process. We have also identified flows with a velocity of 20–50 km s−1 toward the footpoints of the newly formed coronal loops.
Les variantes du goût universitaire
Authors: Gabrysiak Louis 
Published: July 2021

Cet article s’intéresse, à partir d’une double enquête quantitative et qualitative, aux styles de vie des universitaires et aux luttes culturelles internes à l’université. L’université a connu, ces dernières décennies, des transformations morphologiques importantes : l’augmentation du nombre d’étudiant·e·s comme d’enseignant·e·s-chercheur·e·s est allée de pair avec une modification des équilibres disciplinaires, les disciplines les plus classiques, lieux de la culture la plus patrimoniale, connaissent un déclin au profit de disciplines plus récentes, davantage ajustées aux exigences de « professionnalisation », au monde économique. Ce qui nous conduit à interroger l’homogénéité du groupe des universitaires sous l’angle de leurs origines sociales comme de leur rapport à la culture, et permet par là même d’éclairer quelques-unes des tensions qui traversent aujourd’hui l’institution, quant au type de culture qu’elle doit légitimer et transmettre. L’aristocratisme ascétique et la consommation d’œuvres culturelles classiques et patrimoniales continuent d’apparaître dominants dans l’espace universitaire. Mais de nouveaux styles de vie, davantage proches d’une forme d’hédonisme, faits d’un rapport plus distant aux humanités classiques et portés par des disciplines nouvelles viennent concurrencer les disciplines classiques et leur culture, œuvrant alors à la redéfinition du périmètre de la culture légitime.
Remémoration, Répétition, Perlaboration par le jeu vidéo
Authors: Epivent Lucie 
Published: July 2021

À partir de l’analyse du cas clinique d’un enfant de 9 ans, reçu en psychothérapie à la suite d’un vécu traumatique, cet article souhaite éclairer l’usage des jeux vidéo dans la clinique, lorsque le fonctionnement psychique du sujet se retrouve entravé. L’hypothèse soulevée ici est que le jeu vidéo peut venir se placer comme support de reconstruction voire constituer une "tentative de guérison", car il offre un appui vers la symbolisation et mise en représentation. À travers le concept du Moi-Peau de D.Anzieu réactualisé par le Moi-Cyborg (F. Tordo), il est question ici d’explorer la reconstruction des enveloppes psychiques à travers le numérique. En se mettant dans la peau d’un autre par le biais de l’avatar, c’est en réalité un double numérique qui se déploie pour tenter de résoudre des conflits internes en examinant diverses potentialités.
« Au dire des hommes, qui est le Fils de l’homme ? » (Mt 16,13) Étude narrative de l’expression « le fils de l’homme » dans les évangiles synoptiques
Authors: Monzani Paolo 
Published: July 2021

L’expression « le fils de l’homme » dans les évangiles synoptiques est à la fois très débattue et sous-exploitée en christologie. À travers l’analyse narrative des prises de parole de Jésus et des titres qui lui sont attribués, on conclut que « fils de l’homme » n’est pas un véritable titre, mais une expression ouverte qui se développe au long du récit évangélique. Elle demande finalement au lecteur de prendre position face au mystère de Jésus.
The Deaf Community's Experiences Navigating COVID-19 Pandemic Information

Background:
Users of American Sign Language (ASL) who are deaf often face barriers receiving health information, contributing to significant gaps in health knowledge and health literacy. To reduce the spread of coronavirus disease 2019 (COVID-19) and its risk to the public, the government and health care providers have encouraged social distancing, use of face masks, hand hygiene, and quarantines. Unfortunately, COVID-19 information has rarely been available in ASL, which puts the deaf community at a disadvantage for accessing reliable COVID-19 information.

Objective:
This study's primary objective was to compare COVID-19–related information access between participants who are deaf and participants who are hearing.

Methods:
The study included 104 adults who are deaf and 74 adults who are hearing who had participated in a prior health literacy study. Surveys were conducted between April and July 2020 via video conference, smartphone apps, or phone calls. COVID-19 data were linked with preexisting data on demographic and health literacy data as measured by the Newest Vital Sign (NVS) and the ASL-NVS.

Key Results:

Neither group of participants differed in their ability to identify COVID-19 symptoms. Adults who are deaf were 4.7 times more likely to report difficulty accessing COVID-19 information (
p
= .011), yet reported using more preventive strategies overall. Simultaneously, adults who are deaf had 60% lower odds of staying home and calling their doctor versus seeking health care immediately or doing something else compared with participants who are hearing if they suspected that they had COVID-19 (
p
= .020).

Conclusions:

Additional education on recommended COVID-19 management and guidance on accessible health care navigation strategies are needed for the deaf community and health care providers. Public health officials should ensure that public service announcements are accessible to all audiences and should connect with trusted agents within the deaf community to help disseminate health information online in ASL through their social media channels.

. 2021;5(2):e162–e170.]

Plain Language Summary:
Compared to participants who are hearing, a higher portion of participants who are deaf reported challenges with accessing, understanding, and trusting COVID-19 information. Although respondents who are deaf had similar knowledge of symptoms compared to participants who are hearing, they used more prevention strategies and were more likely to plan immediate care for suspected symptoms. Improved guidance on COVID-19 management and health care navigation accessible to the deaf community is needed.

Voilà quelques unes des questions pour lesquelles Henri Adamczewski propose son éclairage.
1993 – « Une problématique de la traduction »
Authors: Landois-Maynard Sylvie 
Published: July 2021

Le rôle de la traduction, dans l’acquisition du langage, est mal défini, voire contesté. Le thème et la version traditionnels sont loin de la réalité professionnelle. De plus, la traduction pose des problèmes qui lui sont spécifiques ; et parce qu’elle est à la fois support de langue et comparaison de couples de langue, la méconnaître entraîne des lacunes qui ne manquent pas de nuire à l’acquisition des langues. On formulera cette problématique en dix points, et l’on tentera une approche de résolution.
1997 – « Grille n°2. Activité pédagogique. Enseigner une langue en 3D : jeux, improvisations, théâtre »
Authors: Bardsley Susanna 
Published: July 2021

L’idée de faire des improvisations, des jeux, du « théâtre » avec les étudiants peut effrayer. On n’arrive pas dans la salle avec un tas de documents ; on enlève toutes les tables et toutes les chaises, et l’enseignant n’est plus seul devant des rangs d’étudiants. Le professeur et les étudiants ensemble se mettent en cercle pour commencer un cours de langues. Tous nos repères habituels ont disparu... Cette activité est utilisée en IUT depuis trois ans avec des étudiants en GEA, MI et, depuis la rentrée 1997, en GTR. Cette technique plaît énormément aux étudiants, car elle leur permet de s’exprimer en anglais dans une ambiance ludique. De plus, on constate une amélioration nette à l’oral, ce qui influence aussi les travaux écrits. Cette activité peut être utilisée une fois par an, tous les semestres, tous les mois ou bien toutes les semaines.
1998 – « Peut-on enseigner l'anglais en moins de 48 heures ? »
Authors: Combes-Joncheray Marie-Françoise 
Published: July 2021

Lors de sa conférence au 18e colloque du GERAS, le 13 mars 1997, Jean-Réné Ladmiral a expliqué comment il avait mis en place des stratégies d’enseignement pour permettre à des étudiants de philosophie, n’ayant pas ou peu étudié l’allemand, de décoder les discours des philosophes allemands dans leur version originale. Il s’agissait de proposer une version réduite de la grammaire de la langue cible, et de démonter les structures de la langue de manière à rendre cet apprentissage rapide et efficace, le professeur ne disposant pour mener à bien cette mission que d’un quota d’heures réduit de l’ordre de 35 heures. J.-R Ladmiral a rendu compte du succès de l’opération, possible selon lui grâce à la structure particulière de la langue allemande. À son avis, la même démarche en langue anglaise ne serait par forcément couronnée de succès. Cependant, une mission comparable est menée à bien chque année depuis trois ans à l’Institut Universitaire de Formation des Maîtres (IUFM) de Nantes pour préparer des étudiants d’économie et de gestion (option commerce) à l’épreuve orale bilingue qu’ils ont à présenter au concours du CAPET. La question s’inscrit au cœur d’une question plus vaste : quel anglais enseignons-nous ?
