USING THE TECHNIQUE OF "INFECTING" INTERNAL VISIONS (VISUALIZATION) AS A BASIS FOR SUCCESSFUL TEACHER COMMUNICATION
Authors:   Samara Region Institute of Professional Development and Retraining of Educators, Zaitseva Е.А. , Nuzhdin A.V.
Published: March 2021

Human society is built on communication. Everyone can speak, but not everyone can successfully speak in front of an audience. In the process of public speaking, the speaker has to solve many important tasks simultaneously: to monitor his speech content, to maintain contact with the audience, to manage his body, voice and emotions. A real speaker must know the most advanced methods of constructing speech, be able to express their thoughts clearly and build them in an exact sequence, be convincing, be able to speak concisely, impressively, figuratively. He must be able to attract attention with his appearance, his natural abilities, and the way he speaks and holds himself. For teachers, communication is not only a need and necessity, but also a tool, the main professional tool, and communication skills, knowledge of the basic provisions of the theory of communication, along with special abilities, form the basis of professional competence. The performance should be the work of art that affects the feelings of listeners and their consciousness. To this end, the performances use the technique of "infection" with internal visions (visualization), which is understood as the ability to use vivid images in speech that make the subject of speech brighter, more tangible, and more understandable to convey the idea to the listener. Drawing pictures in the minds of listeners, creating bright and living images using descriptions, metaphors, comparisons, analogies, etc., allows you to make a much greater impact on the audience.

The article is devoted to the analysis of interdisciplinary humanitarian studies and the 30th anniversary of the scientific school established by the Honored Scientist of the Russian Federation, Professor, Doctor of Art History Tatyana Semenovna Zlotnikova. Yaroslavl State Pedagogical University, where the well-known Russian scientific school of cultural studies was born, is also home to the World of the Russian Province Research Center, the Dissertation Council, and several journals reviewed by the Higher Attestation Commission. Professor T.S. Zlotnikova is the founder and scientific leader of these institutions. The success of scientific work is measured today as a global scientific demand, and practical significance for its local space. Scientists from the best research centers in Russia participate in annual "Yaroslavl conferences", grant projects and publications. Yaroslavl cultural projects involve all age and professional levels: from students, undergraduates, postgraduates to doctoral students and professors. However, even with the mass audience, Professor Zlotnikova and her students are talented at building a dialogue. This article deals primarily with the methodology and publishing genres put forward by the Yaroslavl Scientific School of Cultural Studies: an analysis of the creative personality, the concept of Russian mass culture and a fundamentally new textbook on cultural studies. The publications of Professor T. S. Zlotnikova and her colleagues on these problems have a significant heuristic potential, are of high practical significance and have been awarded numerous grants. On the one hand, the 30th anniversary of the Yaroslavl scientific school of cultural studies is a phenomenon of scientific life; on the other hand, the analysis of topical problems of cultural studies based on the material of the multigenre editions of Professor T.S. Zlotnikova is a methodological and research work

Theatre and Post-Truth: KGB Experiences Reflected in the Production “History Research Commission” Directed by Alvis Hermanis
Authors: Mellēna-Bartkeviča Lauma
Published: March 2021

“History Research Commission” staged by Alvis Hermanis in New Riga Theatre (2019) is an example of post-truth coming onto the theatre stage in terms of a rather sensitive subject – historical traumas and unsolved issues that still influence today’s society in Latvia. Hermanis’s production accepts the post-truth as an inevitable and obvious present framework of modern thinking; meanwhile, the subject itself (“cheka bags”) implies the impossibility to find out any “truth” due to its distorted nature from the very beginning. “History Research Commission” paradoxically leads to conclude that the post-truth approach in theatre might be the most honest in terms of today’s world, where the truth has lost its previous status of value. The article covers the short history of “post-truth” analysed by Ralph Keyes, Lee McIntyre, and Yael Brahms. It aims to apply the notion to performing arts through the example of KGB’s experiences in Hermanis’s production (co-created with the actors of the New Riga Theatre) that seems to accept the post-truth and the tragedy of Western rationalism facing the impossibility to find out the provable truth regarding certain subjects. The message of absurdity to chase the truth in “cheka bags” confirms post-truth as the status quo of our time.

EDUCATION OF MORAL QUALITIES IN ADOLESCENT ATHLETES WITH DEVIANT BEHAVIOR
Authors:   Altai State Pedagogical University, Weber D. A.
Published: March 2021

This article deals with theoretical analysis and practical experience of working with adolescents belonging to the group of socio-pedagogical risk. The problem of deviant behavior as a threat to adolescents’ life of is analyzed. The author conducted a study with a group of adolescent athletes with deviant behavior (16 children aged 12-14). Ways of directed education of moral qualities during the process of training and out-of-training time were identified. The conducted research and the results of the development of moral qualities in adolescent athletes with deviant behavior show the correctness of the selection of core qualities for their purposeful education and psychological and pedagogical influence. The fundamental idea of our approach is that this category of adolescents requires particular attention because the age and individual characteristics of adolescents can contribute to delinquent behavior not by themselves, but as a result of creating unfavorable conditions for the life of children or pedagogical errors.

SHEZHIRE OF THE GENUS ESTEK BY GENONYMY AND TRANSIT OF ETHNICITY ISHTYAK / ESTEK IN THE KAZAKH SOCIETY OF THE 18TH-19TH CENTURIES
Authors:   Ch. Valikhanov Institute of History and Ethnology, Ryskildin A. Kh. , Ryskildina D. U. ,   Ch. Valikhanov Institute of History and Ethnology
Published: March 2021

The article deals with the legends of the family of Estek about the events and rituals of integration into the Kazakh community of the 18th century, which can be used to understand the medieval markers of Estek, Ishtyak, Estek, Ostyak, Heshdek as genonyms. There is an extensive and controversial historiography regarding the designations of these concepts, which is explained by differences in sources and methodological preferences. To resolve the contradictions between the Ugric and Turkic etymology of the concepts, various ideas were proposed, including the constructivist interpretation of the yasak subjects in the Urals and Siberia as a socionym. This is indicative of the perception of the yasak estate by the tsarist administrators, but does not exclude the ethnic content of the markers, if we turn to the authentic evidence of the Turkic historical memory.
The Principles Of Typological Study Of Transposition In The Uzbek And Korean Languages
Authors:   Lecturer Tashkent State University Of Oriental Studies, Uzbekistan, Shakhlo Nazarova
Published: March 2021

Like Uzbek, Korean belongs to the Altaic language family, and the sources assume that: a) Korean word forms are agglutinative schemes based on the stem + affix, b) sentences are based on the syntactic scheme of “possessive + second part + cut”, c) the stability of word stress and expiratory character, etc. Additionaly in a word structure the following can be divided: 1) 뾐ꭅ덽: 뾐 + ꭅ + 덽 ; 頝ꃝꍡ겑꽽鲙: 頝 + -ꃝꍡ- + -겑- + -꽽- + -鲙such that cores and appendages can be joined one after the other and separated; 2) according to the function of affix morphemes, «뾐-, -덽-, -ꃝꍡ-» word building, «-겑-, -꽽-, -鲙» 3) the formation of transpositive and non-transpositive artificial words by means of word-forming suffixes, 4) the relative freedom of the transpositive connection between independent, auxiliary words and morphemes also point to this genetic connection.

In recent years, digital technologies have rapidly advanced and are being applied to remedy medical problems. These technologies allow us to monitor and manage our physical and mental health in our daily lives. Since lifestyle modification is the cornerstone of the management of obesity and eating behavior problems, digital therapeutics (DTx) represent a powerful and easily accessible treatment modality. This review discusses the critical issues to consider for enhancing the efficacy of DTx in future development initiatives. To competently adapt and expand public access to DTx, it is important for various stakeholders, including health professionals, patients, and guardians, to collaborate with other industry partners and policy-makers in the ecosystem.
Healthier Streets: How Superblocks and Congestion Pricing Can Help Reduce Air Pollution in Washington, DC
Authors: Navarro-Serer Bernat
Published: March 2021

Cities face big challenges, including environmental threats, livability concerns, lack of new infrastructure, and increasing social inequity, among others. These challenges call for new and innovative ways to address them. Air pollution, a common problem in many cities, causes between 100,000 and 340,000 Americans to die prematurely every year (Fann et al. 2012; Caiazzo et al. 2013; Bowe et al. 2019; and Goodkind et al. 2019) and, out of those premature deaths, 53,000 are due to car pollution (Caiazzo et al. 2013). The Washington DC Metro Area is one of the top 20 cities in the United States with the highest smog pollution, highlighting the need for new regulations to reduce air pollution (American Lung Association 2020). Federal policies aimed at lowering the maximum concentration of air pollutants allowed by the EPA could improve public health, but cities can also reduce air pollution levels through policymaking. DC currently has two main transportation and sustainability plans to improve public transportation, infrastructure, and combat climate change. Cities similar to DC, such as Barcelona and London, have applied superblocks, restricted car access city areas, and congestion pricing policies respectively, aimed at reducing air pollution and improving quality of life. Fortunately, DC has many of the characteristics needed to successfully implement superblocks in areas of the city where residential housing and businesses share space, and congestion pricing in highly congested areas. I recommend the District Department of Transportation to establish pilot programs for each of these policies to reduce air pollution levels in the city.
Permanently Repealing the Global Gag Rule Will Internationally Advance Reproductive and Sexual Health
Authors: Varma Roshni
Published: March 2021

The Global Gag Rule bans foreign nongovernmental organizations (NGOs) that receive U.S. global health assistance funding from providing abortion services and referrals, advocating for abortion rights, or funding other organizations that provide abortion-related services. The rule presents a double bind: if NGOs elect to continue providing abortion-related care, they must forgo U.S. funding, requiring them to roll back services across the board. This reduces access to contraceptives, family planning resources, and maternal and child healthcare. The alternate option is to shut down abortion-related care to retain U.S. funding. Thus, the rule is ineffective in its purpose as it creates barriers to comprehensive sexual and reproductive healthcare, leading to increases in unintended pregnancies, abortions, and newborn and maternal death rates. In addition, restricted funding has negative implications for HIV/AIDS and reproductive cancer screening and treatment. The rule is currently implemented and repealed by each incoming president using executive orders. The United States Congress should pass the Global Health, Empowerment, and Rights Act and repeal the Helms Amendment. This will permanently revoke the Global Gag Rule and reduce unintended pregnancies, abortions, and child and maternal mortality rates across the world.

A Spatially Resolved Survey of Distant Quasar Host Galaxies. II. Photoionization and Kinematics of the ISM
Authors: Vayner Andrey , Wright Shelley A. , Murray Norman , Armus Lee , Boehle Anna , Cosens Maren , Larkin James E. , Mieda Etsuko , Walth Gregory
Published: March 2021

We present detailed observations of photoionization conditions and galaxy kinematics in 11 z = 1.39–2.59 radio-loud quasar host galaxies. Data were taken with the OSIRIS integral field spectrograph and the adaptive optics system at the W. M. Keck Observatory that targeted nebular emission lines (Hβ, [O iii], Hα, [N ii]) redshifted into the near-infrared (1–2.4 μm). We detect extended ionized emission on scales ranging from 1 to 30 kpc photoionized by stars, shocks, and active galactic nuclei (AGN). Spatially resolved emission-line ratios indicate that our systems reside off the star formation and AGN-mixing sequence on the Baldwin, Phillips, & Terlevich diagram at low redshift. The dominant cause of the difference between line ratios of low-redshift galaxies and our sample is due to lower gas-phase metallicities, which are 2–5× less compared to galaxies with AGN in the nearby universe. Using gas velocity dispersion as a proxy to stellar velocity dispersion and dynamical mass measurement through inclined disk modeling, we find that the quasar host galaxies are undermassive relative to their central supermassive black hole mass, with all systems residing off the local scaling (M
•–σ, M
•–M
*) relationship. These quasar host galaxies require substantial growth, up to an order of magnitude in stellar mass, to grow into present-day massive elliptical galaxies. Combining these results with part I of our sample paper, we find evidence for winds capable of causing feedback before the AGN host galaxies land on the local scaling relation between black hole and galaxy stellar mass, and before the enrichment of the interstellar medium to a level observed in local galaxies with AGN.
Observational Constraints in Delta-gravity: CMB and Supernovae
Authors: Martín Marco San , Alfaro Jorge , Rubio Carlos
Published: March 2021

Delta-gravity (DG) is a gravitational model based on an extension of general relativity given by a new symmetry called

. In this model, new matter fields are added to the original matter fields, motivated by the additional symmetry. We call them

matter fields. This model predicts an accelerating universe without the need to introduce a cosmological constant. In this work, we study the scalar cosmic microwave background (CMB) temperature (TT) power spectrum predicted by DG using an analytical hydrodynamic approach. To fit the Planck satellite’s data with the DG model, we used a Markov Chain Monte Carlo analysis. We also include a study about the compatibility between Type Ia supernovae (SNe Ia) and CMB observations in the DG context. Finally, we obtain the scalar CMB TT power spectrum and the fitted parameters needed to explain both SN Ia data and CMB measurements. The results are in reasonable agreement with both observations considering the analytical approximation. We also discuss whether the Hubble constant and the accelerating universe are in concordance with the observational evidence in the DG context.

We present our photometric and spectroscopic observations of the peculiar transient AT2018cow. The multiband photometry covers from peak to ∼70 days, and the spectroscopy ranges from 5 to ∼50 days. The rapid rise (t
r ≲ 2.9 days), high luminosity (M

V,peak ∼ −20.8 mag), and fast decline after peak make AT2018cow stand out from any other optical transients, whereas we find that its light curves show a high resemblance to those of Type Ibn supernovae. Moreover, the spectral energy distribution remains at a high temperature of ∼14,000 K at t > 15 days after discovery. The spectra are featureless in the first 10 days, while some broad emission lines due to H, He, C, and O emerge later, with velocity declining from ∼14,000 to ∼3000 km s−1 at the end of our observations. Narrow and weak He I emission lines emerge in the spectra at t > 20 days after discovery. These emission lines are reminiscent of the features seen in interacting supernovae like the Type Ibn and IIn subclasses. We fit the bolometric light curves with a model of circumstellar interaction and radioactive decay of 56Ni and find a good fit with ejecta mass M
ej ∼ 3.16 M
⊙, circumstellar medium (CSM) mass M
CSM ∼ 0.04 M
⊙, and ejected 56Ni mass

M
⊙. The CSM shell might be formed in an eruptive mass ejection of the progenitor star. Furthermore, the host environment of AT2018cow implies a connection of AT2018cow with massive stars. Combining observational properties and the light-curve fitting results, we conclude that AT2018cow might be a peculiar interacting supernova that originated from a massive star.
Multiwavelength Observations of the Formation and Eruption of a Complex Filament
Authors: Zhang Y. , Bastian T. S. , Liu J. H. , Yu S. J. , Feng S. , Chen J. , Yan Y. H.
Published: March 2021

We present an analysis of the formation and eruption of a filament and fast coronal mass ejection associated with a flare that occurred in active region 11429 using observations in the ultraviolet, extreme ultraviolet, X-ray, and radio wavelength bands. Precursor activity began as an interaction between two filaments, F1 and F2, that are identified as having twisted magnetic flux ropes (MFRs). Transient brightenings in all wavelengths are observed as a result of this interaction, likely the result of magnetic reconnection between the two filaments. This interaction results in a reconfiguration of the two filaments into a long overlying filament and a shorter low-lying filament. The upper filament subsequently undergoes a partial confined eruption. Plasma flows originating near the east footpoint of F1 lead to an extension of the upper filament into the filament channel to the west, resulting in a new active region filament (ARF). This new filament begins a slow rise and expansion. During its slowly rising phase, the MFR in which the filament is embedded becomes visible, with both the filament and flux rope rising and expanding simultaneously. The twist of the magnetic rope is determined as four turns. The erupting configuration changes from a twisted arch shape to a reversed γ shape within ∼75 s at the beginning of the fast-rise phase, representing a transformation from twist to writhe. The observations provide a clear example of filament formation via the tether-cutting reconnection of two nearby filaments. A helical kink instability may be the trigger of the ARF eruption.

Published: March 2021

We investigate the use of approximate Bayesian neural networks (BNNs) in modeling hundreds of time delay gravitational lenses for Hubble constant (H
0) determination. Our BNN was trained on synthetic Hubble Space Telescope quality images of strongly lensed active galactic nuclei with lens galaxy light included. The BNN can accurately characterize the posterior probability density functions (PDFs) of model parameters governing the elliptical power-law mass profile in an external shear field. We then propagate the BNN-inferred posterior PDFs into an ensemble H
0 inference, using simulated time delay measurements from a plausible dedicated monitoring campaign. Assuming well-measured time delays and a reasonable set of priors on the environment of the lens, we achieve a median precision of 9.3% per lens in the inferred H
0. A simple combination of a set of 200 test lenses results in a precision of 0.5 km s−1 Mpc−1 (0.7%), with no detectable bias in this H
0 recovery test. The computation time for the entire pipeline—including the generation of the training set, BNN training and H
0 inference—translates to 9 minutes per lens on average for 200 lenses and converges to 6 minutes per lens as the sample size is increased. Being fully automated and efficient, our pipeline is a promising tool for exploring ensemble-level systematics in lens modeling for H
0 inference.

Constraining Jupiter’s internal structure is crucial for understanding its formation and evolution history. Recent interior models of Jupiter that fit Juno’s measured gravitational field suggest an inhomogeneous interior and potentially the existence of a diluted core. These models, however, strongly depend on the model assumptions and the equations of state used. A complementary modeling approach is to use empirical structural models. These can later be used to reveal new insights into the planetary interior and be compared to standard models. Here we present empirical structural models of Jupiter where the density profile is constructed by piecewise-polytropic equations. With these models we investigate the relation between the normalized moment of inertia (MoI) and the gravitational moments J
2 and J
4. Given that only the first few gravitational moments of Jupiter are measured with high precision, we show that an accurate and independent measurement of the MoI value could be used to further constrain Jupiter’s interior. An independent measurement of the MoI with an accuracy better than ∼0.1% could constrain Jupiter’s core region and density discontinuities in its envelope. We find that models with a density discontinuity at ∼1 Mbar, as would produce a presumed hydrogen–helium separation, correspond to a fuzzy core in Jupiter. We next test the appropriateness of using polytropes, by comparing them with empirical models based on polynomials. We conclude that both representations result in similar density profiles and ranges of values for quantities like core mass and MoI.

We report the temporal and spectral analysis of three thermonuclear X-ray bursts from 4U 1608−52, observed by the Neutron Star Interior Composition Explorer (NICER) during and just after the outburst observed from the source in 2020. In two of the X-ray bursts, we detect secondary peaks 30 and 18 s after the initial peaks. The secondary peaks show a fast rise exponential decay-like shape resembling a thermonuclear X-ray burst. Time-resolved X-ray spectral analysis reveals that the peak flux, blackbody temperature, and apparent emitting radius values of the initial peaks are in agreement with X-ray bursts previously observed from 4U 1608−52, while the same values for the secondary peaks tend toward the lower end of the distribution of bursts observed from this source. The third X-ray burst, which happened during much lower accretion rates, did not show any evidence for a deviation from an exponential decay and was significantly brighter than the previous bursts. We present the properties of the secondary peaks and discuss the events within the framework of short recurrence time bursts or bursts with secondary peaks. We find that the current observations do not fit in standard scenarios and challenge our understanding of flame spreading.
Deciphering the Kinematic Structure of the Small Magellanic Cloud through Its Red Giant Population
Authors: Zivick Paul , Kallivayalil Nitya , van der Marel Roeland P.
Published: March 2021

We present a new kinematic model for the Small Magellanic Cloud (SMC), using data from the Gaia Data Release 2 catalog. We identify a sample of astrometrically well-behaved red giant (RG) stars belonging to the SMC and cross-match with publicly available radial velocity (RV) catalogs. We create a 3D spatial model for the RGs, using RR Lyrae for distance distributions, and apply kinematic models with varying rotation properties and a novel tidal expansion prescription to generate mock proper motion (PM) catalogs. When we compare this series of mock catalogs to the observed RG data, we find that a combination of moderate rotation (with a magnitude of ∼10–20 km s−1 at 1 kpc from the SMC center, inclination between ∼50 and 80°, and a predominantly north-to-south line-of-nodes position angle of ∼180°) and tidal expansion (with a scaling of ∼10 km s−1 kpc−1) is required to explain the PM signatures. The exact best-fit parameters depend somewhat on whether we assess only the PMs or include the RVs as a qualitative check, leaving some tension remaining between the PM and RV conclusions. In either case, the parameter space preferred by our model is different from previously inferred rotational geometries, including from the SMC H i gas, and from the RG RV-only analyses and new SMC PM analyses, which conclude that a rotation signature is not detectable. Taken together this underscores the need to treat the SMC as a series of different populations with distinct kinematics.
Convective Overshooting in the Envelopes of A-type Stars Using the k-ω Model
Authors: Guo Fei , Li Yan
Published: March 2021

Mixing between convective zones is quite uncertain in the envelopes of A-type stars. To study the mixing in A-type envelopes, we use a new convection model, the k-ω model, in the MESA stellar evolution code. Using the k-ω model, we find that the overshooting regions of the He ii and H/He i convection zones are integrated with each other. There is material exchange between the He ii and H/He i convection zones through overshooting, in agreement with recent numerical simulations.We obtain the overshooting distance of about 3.5H
p below the base of the H/He i convection zone in a 2.3 M
⊙ star. There are two overshooting regions beyond the He ii convection zone in the same stellar model. We obtain that the overshooting distance of the upper one is about 3.9H
p and about 2.0H
p for the lower one. We find that the turbulent diffusion effect is particularly strong in the convective envelopes of A-type stars. In addition, we find that the typical size of the convective rolling cells is restricted by the actual thickness of the convective zones, because the thickness of the convection zones are usually smaller than or approximately equal to the local pressure scale height. Through comparisons with the results of the k-ω model, we find that a suitable value of f
ov is about 0.45 for the H/He i convective overshooting region. It is about 0.27 for the upper He ii convective overshooting region and about 0.25 for the lower one.
The Thermal and Gravitational Energy Densities in the Large-scale Structure of the Universe

As cosmic structures form, matter density fluctuations collapse gravitationally and baryonic matter is shock-heated and thermalized. We therefore expect a connection between the mean gravitational potential energy density of collapsed halos,

, and the mean thermal energy density of baryons, Ωth. These quantities can be obtained using two fundamentally different estimates: we compute

using the theoretical framework of the halo model, which is driven by dark matter statistics, and measure Ωth using the Sunyaev–Zeldovich (SZ) effect, which probes the mean thermal pressure of baryons. First, we derive that, at the present time, about 90% of

originates from massive halos with M > 1013
M
⊙. Then, using our measurements of the SZ background, we find that Ωth accounts for about 80% of the kinetic energy of the baryons available for pressure in halos at z ≲ 0.5. This constrains the amount of nonthermal pressure, e.g., due to bulk and turbulent gas motion sourced by mass accretion, to be about Ωnon‐th ≃ 0.4 × 10−8 at z = 0.
Use of computational fluid dynamics tools to calculate the dispersion of gas and aerosol emissions in conditions of a complex terrain

Published: March 2021

ANSYS FLUENT tools were used as part of a standard turbulence k-ε model to simulate the air flow around a number of typical obstacles (a solid cube, a solid hemisphere, and a 2D hill) which form a potential terrain in the NPP emission dispersion area and roughly correspond to the geometry of the buildings and structures within this area. For reproducibility, a non-uniform spatial grid is plotted in the computational region which condenses near the obstacle surface and the outer boundaries. The dimensions and the positions of the obstacles were chosen such that to ensure their best possible coincidence with the conditions of the published experiments. The result of simulating the velocity and direction of the air flow as the whole shows a good agreement with the data from the wind tunnel experiments in the areas in front of and over the obstacle, as well as in its air shadow. Typical accelerated flow, vortex, and reverse flow areas are reproduced reliably. There are variances observed only in the local heavy turbulence regions in the obstacle’s air shadow near the ground surface. All this indicates that it is possible to model in full scale the dispersion of the NPP emissions taking into account the peculiarities of the plant site terrain and the major onsite structures to determine more accurately the personnel and public exposure dose.

Confinement, déconfinement, reconfinement, où est donc le nord ?
Authors: de Thé Priscille
Published: March 2021

Dans le tourbillon actuel de la crise sanitaire, retrouver le nord est un fameux défi. À hauteur d’Hommes, sans doute, mais défi quand même. Alors que beaucoup d’émotions nous sont comme imposées de l’extérieur, en même temps que des chiffres et des consignes, il est important de revenir à soi, de dégonfler la pression du ballon pour retrouver ou garder notre capacité à penser, à agir, à aimer, jouer et travailler. Comment faire ? Un chemin semble nous être proposé, exigeant et puissant en même temps : celui d’accorder notre rythme intérieur au rythme extérieur dans sa version confinée, de prendre le temps de prêter attention à ce qui fait nos vies, ce qui a du goût pour nous, ce qui nous pèse, ce qui nous attire. Cette crise révèle, elle laisse apparaître, et d’une certaine façon elle nous convoque. Et si elle voulait, elle aussi, jouer en notre faveur, sur les plans à la fois personnel et collectif ?
