Gravitationally lensed supernovae (LSNe) are important probes of cosmic expansion, but they remain rare and difficult to find. Current cosmic surveys likely contain 5–10 LSNe in total while next-generation experiments are expected to contain several hundred to a few thousand of these systems. We search for these systems in observed Dark Energy Survey (DES) five year SN fields—10 3 sq. deg. regions of sky imaged in the griz bands approximately every six nights over five years. To perform the search, we utilize the DeepZipper approach: a multi-branch deep learning architecture trained on image-level simulations of LSNe that simultaneously learns spatial and temporal relationships from time series of images. We find that our method obtains an LSN recall of 61.13% and a false-positive rate of 0.02% on the DES SN field data. DeepZipper selected 2245 candidates from a magnitude-limited (m

< 22.5) catalog of 3,459,186 systems. We employ human visual inspection to review systems selected by the network and find three candidate LSNe in the DES SN fields.

We present analysis of the light curves (LCs) of 77 hydrogen-poor superluminous supernovae (SLSNe I) discovered during the Zwicky Transient Facility Phase I operation. We find that the majority (67%) of the sample can be fit equally well by both magnetar and ejecta–circumstellar medium (CSM) interaction plus 56Ni decay models. This implies that LCs alone cannot unambiguously constrain the physical power sources for an SLSN I. However, 23% of the sample show inverted V-shape, steep-declining LCs or features of long rise and fast post-peak decay, which are better described by the CSM+Ni model. The remaining 10% of the sample favors the magnetar model. Moreover, our analysis shows that the LC undulations are quite common, with a fraction of 18%–44% in our gold sample. Among those strongly undulating events, about 62% of them are found to be CSM-favored, implying that the undulations tend to occur in the CSM-favored events. Undulations show a wide range in energy and duration, with median values (and 1σ errors) being as

days, respectively. Our analysis of the undulation timescales suggests that intrinsic temporal variations of the central engine can explain half of the undulating events, while CSM interaction (CSI) can account for the majority of the sample. Finally, all of the well-observed He-rich SLSNe Ib either have strongly undulating LCs or the LCs are much better fit by the CSM+Ni model. These observations imply that their progenitor stars have not had enough time to lose all of the He-envelopes before supernova explosions, and H-poor CSM are likely to present in these events.

The statistics of galactic-scale quasar pairs can elucidate our understanding of the dynamical evolution of supermassive black hole (SMBH) pairs, the duty cycles of quasar activity in mergers, or even the nature of dark matter, but they have been challenging to measure at cosmic noon, the prime epoch of massive galaxy and SMBH formation. Here we measure a double quasar fraction of ∼6.2 ± 0.5 × 10−4 integrated over ∼0.″3–3″ separations (projected physical separations of ∼3–30 kpc at z ∼ 2) in luminous (L
bol > 1045.8 erg s−1) unobscured quasars at 1.5 < z < 3.5 using Gaia EDR3-resolved pairs around SDSS DR16 quasars. The measurement was based on a sample of 60 Gaia-resolved double quasars (out of 487 Gaia pairs dominated by quasar+star superpositions) at these separations, corrected for pair completeness in Gaia, which we quantify as functions of pair separation, magnitude of the primary, and magnitude contrast. The double quasar fraction increases toward smaller separations by a factor of ∼5 over these scales. The division between physical quasar pairs and lensed quasars in our sample is currently unknown, requiring dedicated follow-up observations (in particular, deep, subarcsecond-resolution IR imaging for the closest pairs). Intriguingly, at this point, the observed pair statistics are in rough agreement with theoretical predictions both for the lensed quasar population in mock catalogs and for dual quasars in cosmological hydrodynamic simulations. Upcoming wide-field imaging/spectroscopic space missions such as Euclid, CSST, and Roman, combined with targeted follow-up observations, will conclusively measure the abundances and host galaxy properties of galactic-scale quasar pairs, offset AGNs, and subarcsecond lensed quasars across cosmic time.
A Standard Siren Measurement of the Hubble Constant Using Gravitational-wave Events from the First Three LIGO/Virgo Observing Runs and the DESI Legacy Survey

We present a new constraint on the Hubble constant H
0 using a sample of well-localized gravitational-wave (GW) events detected during the first three LIGO/Virgo observing runs as dark standard sirens. In the case of dark standard sirens, a unique host galaxy is not identified, and the redshift information comes from the distribution of potential host galaxies. From the third LIGO/Virgo observing run detections, we add the asymmetric-mass binary black hole GW190412 and the high-confidence GW candidates S191204r, S200129m, and S200311bg to the sample of dark standard sirens analyzed in Palmese et al. Our sample contains the top 20% (based on localization) GW events and candidates to date with significant coverage by the Dark Energy Spectroscopic Instrument Legacy Survey. We combine the H

A Component of the Smith High-velocity Cloud Now Crossing the Galactic Plane
Authors: Lockman Felix J. , Benjamin Robert A. , Pichette Nicolas , Thibodeau Christopher
Published: January 2023

We have identified a new structure in the Milky Way: a leading component of the Smith high-velocity cloud that is now crossing the Galactic plane near longitude 25°. Using new 21 cm H i data from the Green Bank Telescope (GBT), we measured the properties of several dozen clouds that are part of this structure. Their kinematics is consistent with that of the Smith Cloud with a V
LSR exceeding that permitted by circular rotation in their direction. Most of the clouds in the leading component show evidence that they are interacting with disk gas allowing the location of the interaction to be estimated. The leading component crosses the Galactic plane at a distance from the Sun of 9.5 kpc, about 4.5 kpc from the Galactic Center. Its H i mass may be as high as 106
M
⊙, comparable to the mass of the neutral component of the Smith Cloud, but only a fraction of this is contained in clouds that are resolved in the GBT data. Like the Smith Cloud, the leading component appears to be adding mass and angular momentum to the interstellar medium in the inner Galaxy. We suggest that the Smith Cloud is not an isolated object, but rather part of a structure that stretches more than 40° (∼7 kpc) across the sky, in two pieces separated by a gap of ∼1 kpc.

) star-forming galaxies (SFGs) and quiescent galaxies (QGs) at redshift z
obs ∼ 2 to investigate the joint evolution of star formation activity and structural properties. Compared to extended SFGs, compact SFGs are more likely to have experienced multiple star formation episodes, with the fractional mass formed during the older (≥1 Gyr) episode being larger, suggesting that high-redshift SFGs assembled their central regions earlier and then kept growing in central mass as they become more compact. The SFH of compact QGs does not significantly differ from the average for this category, and shows an early burst followed by a gradual decline of the star formation rate. The SFH of extended QGs, however, is similar to that of post-starburst galaxies, and their morphology is also frequently disturbed. Knowledge of the SFH also enables us to empirically reconstruct the structural evolution of individual galaxies. While the progenitor effect is clearly observed and accounted for in our analysis, it alone is insufficient to explain the observed structural evolution. We show that, as they evolve from star-forming phase to quiescence, galaxies grow massive dense stellar cores. Quenching begins at the center and then propagates outward to the rest of the structure. We discuss possible physical scenarios for the observed evolution and find that our empirical constraints are in good quantitative agreement with the model predictions from dissipative accretion of gas to the center followed by massive starbursts before final quiescence (wet compaction).
A Combined Radio Multi-Survey Catalog of Fermi Unassociated Sources
Authors: Bruzewski S. , Schinzel F. K. , Taylor G. B.
Published: January 2023

Approximately one-third of existing γ-ray sources identified by the Fermi Gamma-Ray Space Telescope are considered to be unassociated, with no known counterpart at other frequencies/wavelengths. These sources have been the subject of intense scrutiny and observational effort during the observatory’s mission lifetime, and here we present a method of leveraging existing radio catalogs to examine these sources without the need for specific dedicated observations, which can be costly and complex. Via the inclusion of many sensitive low-frequency catalogs we specifically target steep-spectrum sources such as pulsars. This work has found steep-spectrum radio sources contained inside 591 Fermi unassociated fields, with at least 21 of them being notable for having pulsar-like γ-ray properties as well. We also identify a number of other fields of interest based on various radio and γ-ray selections.
NOEMA Detection of Circumnuclear Molecular Gas in X-Ray Weak Dual Active Galactic Nuclei: No Evidence for Heavy Obscuration
Authors: Hou Meicun , Li Zhiyuan , Liu Xin , Li Zongnan , Li Ruancun , Wang Ran , Wang Jing , Ho Luis C.
Published: January 2023

Dual active galactic nuclei (AGNs), which are the manifestation of two actively accreting supermassive black holes (SMBHs) hosted by a pair of merging galaxies, are a unique laboratory for studying the physics of SMBH feeding and feedback during an indispensable stage of galaxy evolution. In this work, we present NOEMA CO(2–1) observations of seven kiloparsec-scale dual-AGN candidates drawn from a recent Chandra survey of low redshift, optically classified AGN pairs. These systems are selected because they show unexpectedly low 2–10 keV X-ray luminosities for their small physical separations signifying an intermediate-to-late stage of merger. Circumnuclear molecular gas traced by the CO(2–1) emission is significantly detected in six of the seven pairs and 10 of the 14 nuclei, with an estimated mass ranging between (0.2–21) × 109
M
⊙. The primary nuclei, i.e., the ones with the higher stellar velocity dispersion, tend to have a higher molecular gas mass than the secondary. Most CO-detected nuclei show a compact morphology, with a velocity field consistent with a kiloparsec-scale rotating structure. The inferred hydrogen column densities range between 5 × 1021–2 × 1023 cm−2, but mostly at a few times 1022 cm−2, in broad agreement with those derived from X-ray spectral analysis. Together with the relatively weak mid-infrared emission, the moderate column density argues against the prevalence of heavily obscured, intrinsically luminous AGNs in these seven systems, but favors a feedback scenario in which AGN activity triggered by a recent pericentric passage of the galaxy pair can expel circumnuclear gas and suppress further SMBH accretion.
MeV Gamma-Ray Source Contribution to the Inner Galactic Diffuse Emission
Authors: Tsuji Naomi , Inoue Yoshiyuki , Yoneda Hiroki , Mukherjee Reshmi , Odaka Hirokazu
Published: January 2023

The origin of the inner Galactic emission, measured by COMPTEL with a flux of ∼10−2 MeV cm−2 s−1 sr−1 in the 1–30 MeV energy range from the inner Galactic region, has remained unsettled since its discovery. In this paper, we elaborate on a model of individual MeV gamma-ray sources unresolved by COMPTEL. This is conducted for sources crossmatched between the Swift-BAT and Fermi-LAT catalogs by interpolating the energy spectra in the hard X-ray and GeV gamma-ray ranges, as well as unmatched sources between the two catalogs. We find that the source contribution to the COMPTEL emission would be at least ∼20%. Combined with the Galactic diffuse emission, which is not well constrained, the COMPTEL emission can be roughly reproduced in some cases.
CARMA-NRO Orion Survey: Unbiased Survey of Dense Cores and Core Mass Functions in Orion A

The mass distribution of dense cores is a potential key to understanding the process of star formation. Applying dendrogram analysis to the CARMA-NRO Orion C18O (J = 1–0) data, we identify 2342 dense cores, about 22% of which have virial ratios smaller than 2 and can be classified as gravitationally bound cores. The derived core mass function (CMF) for bound starless cores that are not associate with protostars has a slope similar to Salpeter’s initial mass function (IMF) for the mass range above 1 M
⊙, with a peak at ∼0.1 M
⊙. We divide the cloud into four parts based on decl., OMC-1/2/3, OMC-4/5, L1641N/V380 Ori, and L1641C, and derive the CMFs in these regions. We find that starless cores with masses greater than 10 M
⊙ exist only in OMC-1/2/3, whereas the CMFs in OMC-4/5, L1641N, and L1641C are truncated at around 5–10 M
⊙. From the number ratio of bound starless cores and Class II objects in each subregion, the lifetime of bound starless cores is estimated to be 5–30 freefall times, consistent with previous studies for other regions. In addition, we discuss core growth by mass accretion from the surrounding cloud material to explain the coincidence of peak masses between IMFs and CMFs. The mass accretion rate required for doubling the core mass within a core lifetime is larger than that of Bondi–Hoyle accretion by a factor of order 2. This implies that more dynamical accretion processes are required to grow cores.
Pixel-to-pixel Translation of Solar Extreme-ultraviolet Images for DEMs by Fully Connected Networks

Published: January 2023

In this study, we suggest a pixel-to-pixel image translation method among similar types of filtergrams such as solar extreme-ultraviolet (EUV) images. For this, we consider a deep-learning model based on a fully connected network in which all pixels of solar EUV images are independent of one another. We use six-EUV-channel data from the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO), of which three channels (17.1, 19.3, and 21.1 nm) are used as the input data and the remaining three channels (9.4, 13.1, and 33.5 nm) as the target data. We apply our model to representative solar structures (coronal loops inside of the solar disk and above the limb, coronal bright point, and coronal hole) in SDO/AIA data and then determine differential emission measures (DEMs). Our results from this study are as follows. First, our model generates three EUV channels (9.4, 13.1, and 33.5 nm) with average correlation coefficient values of 0.78, 0.89, and 0.85, respectively. Second, our model generates the solar EUV data with no boundary effects and clearer identification of small structures when compared to a convolutional neural network–based deep-learning model. Third, the estimated DEMs from AI-generated data by our model are consistent with those using only SDO/AIA channel data. Fourth, for a region in the coronal hole, the estimated DEMs from AI-generated data by our model are more consistent with those from the 50 frames stacked SDO/AIA data than those from the single-frame SDO/AIA data.
Highly Energetic Electrons Accelerated in Strong Solar Flares as a Preferred Driver of Sunquakes
Authors: Wu H. , Dai Y. , Ding M. D.
Published: January 2023

Sunquakes are enhanced seismic waves excited in some energetic solar flares. Up to now, their origin has still been controversial. In this Letter, we select and study 20 strong flares in Solar Cycle 24, whose impulse phase is fully captured by the Reuven Ramaty High Energy Solar Spectroscopic Imager. For 11 out of 12 sunquake-active flares in our sample, the hard X-ray emission shows a good temporal and spatial correlation with the white-light enhancement and the sunquake. Spectral analysis also reveals a harder photon spectrum that extends to several hundred keV, implying a considerable population of flare-accelerated nonthermal electrons at high energies. Quantitatively, the total energy of electrons above 300 keV in sunquake-active flares is systematically different from that in sunquake-quiet flares, while the difference is marginal for electrons above 50 keV. All these facts support highly energetic electrons as a preferred driver of the sunquakes. Such an electron-driven scenario can be reasonably accommodated in the framework of a recently proposed selection rule for sunquake generation. For the remaining one event, the sunquake epicenter is cospatial with a magnetic imprint, i.e., a permanent change of magnetic field on the photosphere. Quantitative calculation shows that the flare-induced downward Lorentz force can do enough work to power the sunquake, acting as a viable sunquake driver for this specific event.
Improved technology of frequency-selective UHF electromagnetic shields containing helical elements
Authors: Boiprav Olga V. , Bogush Natalia V.
Published: January 2023

An improved technology of frequency-selective electromagnetic shields has been considered. The technology has been improved by embedding classic Archimedean helical elements made from foiled materials into the bulk of the shields for the improvement of the frequency-selective performance of the shields and pinning of these elements in the bulk of the shields by means of fusion bonding. These design features provide for the main advantage of the improved technology in comparison with counterparts, i.e., lower time consumption. The technology has been improved in the following two aspects: 1) identification of helical element parameters providing for the greatest energy loss of the UHF electromagnetic radiation interacting with the helical elements; 2) identification of the optimum helical element arrangement in the shield bulk providing for the smallest transmission and reflection coefficient of the UHF electromagnetic radiation by the shields. Technology improvement in accordance with the former of the above aspects has been achieved based on analysis of publications dealing with mathematical simulation and study of the parameters of UHF electromagnetic radiation transmission by planar helical antennas. Technology improvement in accordance with the latter aspect has been achieved based on experimental data. Test shields have been fabricated with specifically arranged embedded helical elements, and comparison has been made between the UHF electromagnetic radiation transmission and reflection coefficients of the shields. Shields fabricated in accordance with the improved technology suggested herein show good promise for the electromagnetic noise protection of electronic devices.

Malgré les incompréhensions qu’elles suscitent, leur apparente incohérence et le sentiment qu’elles sont avant tout guidées par l’urgence, les réformes éducatives menées ces dernières années s’inscrivent dans un mouvement d’ensemble que l’on peut qualifier de néolibéral. Avec des nuances, non sans quelques divergences et contradictions, elles sont guidées par quelques principes communs parmi lesquels la recherche de la plus grande performance des individus, des établissements et du système par leur mise en concurrence. Dans ce cadre institutionnel en mutation, le syndicalisme doit répondre à de nouveaux défis.

Dans cet article, les fondements méthodologiques et les approches contemporaines de l’analyse des relations interpersonnelles et interethniques sont examinés du point de vue de la psychologie compréhensive, de la psychanalyse, de l’idée de transmission transgénérationnelle et d’autres théories modernes. Les événements ukrainiens de 2013-2014 sont analysés, et les prédispositions historiques des attitudes anti-russes dans l’espace post-soviétique sont explorées. L’auteur décrit systématiquement l’histoire de la formation de la nation et de l’État ukrainiens depuis le XVII e  siècle, lorsque l’Ukraine était sous le protectorat de la Pologne, et explique le rôle particulier de l’hetman d’Ukraine Bohdan Khmelnytsky dans le processus d’adhésion de l’Ukraine à la Russie, mais la nation ukrainienne est devenue une nation divisée. L’auteur décrit le pacte Molotov-Ribbentrop qui a fait de la nation ukrainienne (pour la deuxième fois de son histoire) une nation divisée, ainsi que l’activité des nationalistes ukrainiens pendant la Seconde Guerre mondiale et après sa fin en Ukraine occidentale. L’auteur décrit en détail le soulèvement du peuple ukrainien contre la corruption et les oligarques en 2013 et la transformation du foyer de la colère populaire vers la Russie. L’article accorde une attention particulière au fait que le peuple russe est devenu une nation divisée et a conduit aux relations tendues actuelles entre l’Ukraine et la Russie après l’effondrement de l’Union des républiques socialistes soviétiques (URSS). En conclusion, l’auteur propose un moyen de résoudre ce conflit ethnique.

Le transitionnel et la réflexivité dans la théorisation de René Roussillon : quelle trajectoire pour le jeu et la symbolisation ?

Published: January 2023

Les apports théorico-cliniques de René Roussillon, issus d’un champ de recherche avant tout soutenu par la référence à la psychanalyse, demeurent à plusieurs égards fondamentaux pour penser la question du jeu et de ses avatars. À partir d’un appui solidement ancré sur les apports freudiens et winnicottiens, les propositions déployées par cet auteur invitent à renouveler la pensée sur ce sujet autour de plusieurs notions clés que nous nous proposerons ici de revisiter à partir de la lecture qu’il en effectue : nous évoquerons donc le transitionnel, la symbolisation et la réflexivité ainsi que les différents types de jeu paradigmatiques et le fameux médium malléable. Il s’agira aussi cependant de questionner la pertinence de l’utilisation de ces terminologies dans un domaine différent : celui de la clinique psychomotrice. Jusqu’à quel point ces mêmes apports peuvent-ils dès lors demeurer pertinents à manier en psychomotricité ? Les théories de René Roussillon seraient elles par ailleurs elles-aussi susceptibles de se laisser influencer et modeler par le regard que les psychomotriciens portent sur le jeu ainsi que sur leur manière toute personnelle de l’accompagner, notamment au niveau du corps et de l’acte ? Nous proposerons ici quelques pistes de réponses afin de déployer ces questionnements…
Aspects théorico-cliniques des médiations numériques présentes et à venir en psychomotricité
Authors: Bonnotte Laurent
Published: January 2023

Depuis quelques années, il devient courant de voir les milieux des sciences humaines, des neurosciences et des nouvelles technologies converger vers des recherches communes. Cela implique souvent la création d’un nombre de plus en plus étendu d’interfaces et de logiciels qui mettent en jeu le corps ou encore deviennent de véritables simulateurs de comportements humains. Tout en nous intéressant aux raisons possibles d’un tel engouement, à partir des théories existantes et d’exemples pratiques dans les disciplines impliquées, nous pouvons donner un aperçu de l’importance des notions telles que la sensorimotricité, le schéma-corporel, le dialogue tonique ou encore l’intégration spatio-temporelle dans le développement et l’utilisation de l’outil-numérique. A la question : « Peut-on agir de manière thérapeutique et/ou rééducative sur des troubles psychomoteurs au moyen du numérique ? », le fait de constater qu’il existe déjà des programmes dans le domaine de la clinique psychomotrice ne peut y répondre de manière satisfaisante. Il ne s’agît pas ici de remettre en cause l’efficacité de tels programmes qui, sous forme ludique ou non, se sont avérés utiles pour des patients. Il s’agît plutôt de porter un regard sur les relations existantes entre l’outil, le patient et le thérapeute, mais aussi de nous projeter virtuellement dans celles que nous pouvons aussi envisager de créer.

CoSAGE Community Advisory and Ethics Committee;

Age-related hearing impairment yields many negative outcomes, including alterations in mental health, functional impairments, and decreased social engagement. The purpose of the current study was to examine perceived hearing impairment and its relationship with person-centered outcomes among adults in a rural community setting. A cross-sectional, descriptive correlational design was used. Survey packets of validated instruments were distributed following all weekend services at a rural community church; 72 completed surveys were returned (26% response rate). Descriptive and inferential statistics, including Spearman's rank correlations (r
s
), were used to address the study aims. Mean age of participants was 54 years (
SD
= 17 years), 58% were female, and 97% attended church regularly. Thirty-one percent of respondents reported moderate to severe hearing impairment. Perceived hearing impairment was associated with more depressive symptoms (r
s
= 0.24,
p
= 0.052), poorer attentional function (rs = −0.29,
p
= 0.016), and decreased quality of life in the mental health domain (r
s
= −0.21,
p
= 0.081). Findings expand evidence supporting the relationship between hearing and person-centered outcomes, including a functional measure of cognition. These results serve as a foundation for the design of a community-driven, church-based hearing health intervention. [

Graphon Games: A Statistical Framework for Network Games and Interventions
Authors: Parise Francesca , Ozdaglar Asuman
Published: January 2023

In this paper, we present a unifying framework for analyzing equilibria and designing interventions for large network games sampled from a stochastic network formation process represented by a graphon. To this end, we introduce a new class of infinite population games, termed
graphon games, in which a continuum of heterogeneous agents interact according to a graphon, and we show that equilibria of graphon games can be used to approximate equilibria of large network games sampled from the graphon. This suggests a new approach for design of interventions and parameter inference based on the limiting infinite population graphon game. We show that, under some regularity assumptions, such approach enables the design of asymptotically optimal interventions via the solution of an optimization problem with much lower dimension than the one based on the entire network structure. We illustrate our framework on a synthetic data set and show that the graphon intervention can be computed efficiently and based solely on aggregated relational data.
Invidious Comparisons: Ranking and Selection as Compound Decisions
Authors: Gu Jiaying , Koenker Roger
Published: January 2023

There is an innate human tendency, one might call it the “league table mentality,” to construct rankings. Schools, hospitals, sports teams, movies, and myriad other objects are ranked even though their inherent multi‐dimensionality would suggest that—at best—only partial orderings were possible. We consider a large class of elementary ranking problems in which we observe noisy, scalar measurements of merit fornobjects of potentially heterogeneous precision and are asked to select a group of the objects that are “most meritorious.” The problem is naturally formulated in the compound decision framework of Robbins's (1956) empirical Bayes theory, but it also exhibits close connections to the recent literature on multiple testing. The nonparametric maximum likelihood estimator for mixture models (Kiefer and Wolfowitz (1956)) is employed to construct optimal ranking and selection rules. Performance of the rules is evaluated in simulations and an application to ranking U.S. kidney dialysis centers.
Virtual Site Visits: Student Perception and Preferences Towards Technology Enabled Experiential Learning
Authors: LeBrasseur Richard
Published: January 2023

Site visits are a key pedagogical tool within natural science and geographical education.  Site visits provide an interactive experience to enable learning through the exposure to a real-world spatio-temporal environment. COVID-19 restrictions required the development of a virtual site visit for a landscape ecology course in North America. In this study, a series of digital tools were coordinated to deliver site visit information focusing on multi-sensory, multi-scalar, and multi-media information based on Kolb’s experiential learning model, particularly Step 1, the concrete experience. This research explored student’s perceptions and opinions of the digital tools provided to complete their ecological restoration management assignment and their effectiveness and usability.  4th year natural resource and environmental science students (n=52) reported predominately positive attitudes towards the use of the virtual site visit. Though students did not prefer the virtual site visit over a physical site visit, they noted that the virtual site visit digital tools did provide the same information as a site visit and that they felt they were able to understand all aspects of the physical site through the virtual site visit tools provided, particularly through the digital photographs and the 360-degree virtual reality imagery. Successful student assignments illustrated experiential learning outcomes were met.
Effects of ATDE Teaching Mode during Online Teaching on Creative Thinking Ability of Learners
Authors: Lv Xinwei , Wu Yamin , Cui Xiuli
Published: January 2023

Abstract: Online teaching based on computer and network technology has become a vital teaching mode under the current situation of the overwhelming COVID-19 epidemic. Teachers and students who fully understand and master basic knowledge and skills of various information technologies in online learning can stimulate students’ interest in learning information technology and train their ability in information collection, processing, and use. Given the lack of face-to-face communication and deep emotional exchange, online teaching has poor performance in improving the creative thinking ability of learners. During online teaching, teachers train the innovation consciousness quality of students in online courses successfully and improve the creative thinking ability of learners by using “asking,” “thinking,” “doing,” and “evaluation,” that is, the ATDE teaching mode. In this study, a teaching experiment was carried out on 41 undergraduates admitted in 2018 who majored in civil engineering at Zhengzhou University of Industrial Technology, Henan Province, China. Students were divided into the experimental group and the control group. The experimental group adopted the ATDE teaching mode for the course Design of concrete structure, while the control group applied the traditional teaching mode. A questionnaire survey of students’ creative thinking ability was conducted for both groups. Results showed that university students’ creative, emotional attitude under the ATDE teaching mode was far higher than that under the traditional (F=6.490, p=0.015). The creative thinking performance of university students under the ATDE teaching mode was higher than that under the traditional teaching mode (F=7.468, p=0.009). The Pearson correlation coefficient between creative, emotional attitude and creative thinking performance was 0.985 in the late test stage, which was higher than in the early test stage (0.480), which reveals that the ATDE teaching mode was conducive to improving abstract course learning effect of students majoring in civil engineering. Research conclusions can provide some references to investigate the feasibility of ATDE teaching mode in universities and offer a new choice and feasible path to train students’ creative thinking ability.
Un mythe à détruire : les Vikings et la boussole
Authors: Boyer Régis
Published: January 2023

Le présent article s’en prend à une opinion apparemment séduisante, à savoir que les Vikings auraient disposé d’une boussole sous les espèces d’un quartz piézo-électrique qu’ils appelaient sólarsteinn, pierre solaire. Après avoir rapidement rappelé quels furent les caractères du phénomène viking, on combat ici cette opinion en invoquant tour à tour les témoins dont nous disposons pour en juger (comptes-rendus étrangers, archéologie, savoir nautique et textes en vieux norrois surtout). La conclusion est que ce sólarsteinn, mentionné avec une rareté extrême par ces navigateurs de première force que furent les Scandinaves de l’époque, n’était qu’une pierre précieuse – et que les Vikings n’avaient simplement pas de boussole : on propose quelques conjectures sur la façon dont ils se dirigeaient, mais sans conclusion péremptoire !
La figure du Viking dans la musique métal
Authors: Bénard-Goutouly Nadège
Published: January 2023

Le mythe du Viking véhicule un certain nombre de clichés très éloignés de la réalité historique. Systématiquement repris par les différentes expressions artistiques (peinture, littérature, cinéma, musique), ces clichés contribuent à dresser le portrait d’un homme idéalisé, valeureux et solidaire. Ce sont précisément ces valeurs de courage et de droiture que la musique métal contribue à transmettre depuis les années 1970, et à travers le folk metal – métal folklorique – aujourd’hui. Les groupes appartenant à cette famille musicale adressent un message contestataire à l’égard de la société moderne, jugée déshumanisée, génératrice de solitude et de violence. Ils lui opposent une version enjolivée du passé, le plus souvent celui de leur contrée d’origine, dans laquelle le Viking fait figure d’antimodèle de l’homme contemporain. Le sous-genre viking metal se présente à la fois comme un mouvement contestataire d’envergure internationale et comme le produit même d’une modernité décriée.

History, Hydropower and Hyperbole: Contextualizing the Legal Narrative of the Storm King Mountain Case
Authors: Carpenter Roy
Published: January 2023

Abstract: The so-called “Scenic Hudson case” pitted an alliance of environmental groups against the Continental Edison Power Company, which planned to install the world’s largest hydro station atop Storm King Mountain in the scenic Hudson Highlands region of New York State. The case is famous for revising the legal notion of standing as it pertains to environmental cases, in addition to introducing aesthetic interests as a legitimate factor when considered the impact that public works projects will have for local populations. The fact that the power station was never built seems to confirm that the case constitutes a victory for environmentalism and a significant step forward for environmental law. However, a closer consideration of the laws upon which the decision was based reveals that Scenic Hudson v. Federal Power Commission (1964) merely affirmed already established doctrine and in fact nearly failed to achieve the outcome now hailed as ground breaking. This article re-examines the case in light of this larger legal and political context.
Les eaux courantes et leurs usagers au défi de l’administration de la pollution : le début de l’agence de l’Eau Rhône-Méditerranée-Corse dans la région lyonnaise (fin des années 1960-début des années 1970)
Authors: Frioux Stéphane
Published: January 2023

Résumé : Les agences de bassin, créées à la suite de la loi du 16 décembre 1964, ont été considérées comme un des premiers moyens de lutter pour la protection de l’environnement au sein des années de croissance. Cet article examine, à partir des archives de l’agence de l’eau Rhône-Méditerranée-Corse, comment les débuts de la politique de l’eau ont été pétris, localement, de compromis et de négociations, qui peuvent expliquer les jugements parfois sévères portés par des ouvrages sur l’environnement publiés dans les années 1970.
“The Deadline has Already been Missed”: Wastewater Treatment in Soviet Russia: From Center to Periphery, 1960s–1970s
Authors: Coumel Laurent
Published: January 2023

Abstract: Based on a multiscale survey, this article examines the discourses and practices of wastewater treatment in Soviet Russia between the establishment of a new legislative and institutional framework in 1960 and the middle of the 1980s. While simply placing the question of wastewater treatment on the agenda during this period does present a contrast with the Stalinist era, the institutional proliferation of the 1960s and 1970s constituted an obstacle to improving the ecological health of rivers in certain regions. This is clearly illustrated by the situation in the city of Kalinin (known today as Tver) north-west of Moscow, and in particular the city of Ostashkov, on Lake Seliger. Despite the many alarms raised at the central, regional, and local levels, while well publicized the measures taken did not represent an ecological turn, despite the increase in environmental concerns at the time.
Le ventre comme espace de soin, l’exemple des remèdes secrets purgatifs au xviiie siècle
Authors: Dubois Pauline
Published: January 2023

Résumé : L’expression « prendre une médecine », désignant l’utilisation d’un médicament purgatif, témoigne de la centralité du ventre comme espace thérapeutique à l’époque moderne. Incarnant tous les excès d’une médecine décadente pour les élites éclairées de la seconde moitié du xviiie siècle, des individus appelés charlatans ou empiriques en ont saisi l’importance et commercialisent nombre de remèdes purgatifs. Ces compositions, à la fois considérées comme issues d’un savoir-faire unique par leur propriétaire et comme de mauvaises copies de la pharmacopée officielle par les experts de la Société royale de médecine, s’inscrivent dans une pluralité d’influences provenant autant des charlatans que des milieux savants. Plusieurs définitions de l’innovation, formelle et structurelle, façonnent ces objets massivement utilisés.
De la « matière joyeuse » à la matière vertueuse. Les excréments comme miroir médical et social au xvie siècle
Authors: Chevalier Marine
Published: January 2023

Résumé : Si les matières fécales, qui peuplent le ventre, peuvent être perçues comme de simples déchets organiques, elles ont fait l’objet d’usages thérapeutiques vertueux au fil du temps, de l’Antiquité, avec les usages excrémentiels de Dioscoride et Galien, à aujourd’hui avec les découvertes de Michael Gershon sur le microbiote. C’est le xvie siècle rabelaisien qui centralise ici le propos, avec une observation de l’Œcoïatrie de Christophe Landré. Il s’agira de montrer que ces matières négligées reflètent les conceptions médicales mais également sociales, voire morales, de leur époque.
