IMPACT OF ‘FEE WAIVER SCHEME’ ON THE HIGHER EDUCATION OF STUDENTS IN ASSAM : SOME REFLECTIONS
Authors: Baruah Kamal
Published: January 2023

In India, every year a large number of students are deprived of higher education because of their financial inability to take admission to a college or university. For the first time in India, the state government of Assam has launched a fee waiver scheme to give free admission to economically weaker students. To know the effectiveness of the scheme, an evaluative study was conducted among the beneficiary students from the Kamrup district of Assam. The researcher decided to conduct case studies to serve the purpose. The study attempted to make shreds of evidence on how the fee waiver scheme has impacted the higher education of students in the state.

Groundwater abstraction has grown rapidly in India Since the last few years. One of the major causes is urbanization and industrialization, another major cause of waterlogged agricultural practices. Water is the theme of the State so it is the responsibility of governments to control and manage water resources. But under the Environmental Protection Act, the Central Ground Water Authority may issue guidelines to the provinces. There is currently no central law regarding groundwater management. The problem of groundwater has occurred at a much faster rate than the speed of the law.
Potential of natural fiber composite materials for bulletproof vest applications
Authors: Aminudin Ilham Rizqi , Aritonang Sovian
Published: January 2023

The bulletproof vest material that is often used is a composite material. Composites are a mixture of two or more material elements, with different mechanical properties, which aim to obtain new materials that have better mechanical properties than the constituent materials. One alternative mixture of materials in composite materials is to use natural fibers as a substitute for kevlar fibers. In Indonesia, which has a tropical climate, natural fibers are very easy to obtain from various kinds of plants found in Indonesia. Along with the many plants obtained, a lot of waste is also produced because of this. So research was conducted on the utilization of the potential of natural fibers for alternative composites. With the experimental method, from the results of the experiment, the results obtained from the five natural fibers that have been discussed, namely pineapple leaf fiber, water hyacinth fiber, bark fiber, hemp fiber, and bamboo fiber, only pineapple leaf fiber has not met the National Institute of Justice (NIJ) standard, while the other four natural fibers have met the NIJ standard for bulletproof vests.

NT - 4 - Dides - A conta de estabilização de preços de combustíveis e a disponibilidade de recursos à sua estruturação: O projeto de Lei nº 1.472/2021 em discussão
Authors: Bassi Camillo de Moraes
Published: January 2023

Em 10 de março de 2022, foi aprovado, no Senado Federal, o Projeto de Lei (PL) nº 1.472, de 20 de abril de 2021, objetivando estabilizar os preços dos combustíveis fósseis. Replicando as experiências do Chile e do Peru, o PL nº 1.472/20212 propõe-se a utilização de limites máximo e mínimo às oscilações dos preços, recorrendo a um mecanismo de compensação a essa finalidade. Denominado de Conta de Estabilização de Preços de Combustíveis (CEP-Combustíveis), desembolsará/embolsará recursos, quando o limite atingir seu máximo/mínimo, assim, refreando tanto a alta como a queda abruptas. À sua estruturação, quer dizer, o aporte inicial de capital para viabilizar a empreitada, listam-se algumas fontes de recursos, sem maiores preocupações com o potencial de realização. A situação, frisa-se, fragiliza-se, ainda mais, haja vista que o PL não estima os valores necessários a esse aporte, gerando um cenário (supra) duvidoso, que permite cogitar o próprio êxito da intenta estabilização.
Nesta nota técnica, a proposta é estreitar a dúvida sobredita, discutindo, exatamente, as fontes listadas à estrutura da CEP-Combustíveis. Como os valores destinados a essa finalidade não foram estimados, adotar-se-á uma abordagem alternativa, confrontando a dotação com o potencial de realização destas. O exercício, demonstrado no decorrer da investigação, pode embalar ou arrefecer as possibilidades de êxito, dependendo de quão compromissadas já estão essas fontes – compromisso como parâmetro à rigidez alocativa. Além desta introdução, esta nota técnica disponibiliza, na seção 2, uma breve exposição sobre o tratamento dado à CEP-Combustível pelo PL nº 1.472/2021. Na seção 3, estima-se o potencial de realização das fontes vis-à-vis suas dotações, sinônimo, conforme já anunciado, de uma rigidez alocativa. Na seção 4 (considerações finais), apresentam-se as conclusões e as sugestões da nota técnica.

FACTORS AFFECTING THE ADOPTION OF SOCIAL MEDIA MARKETING IN SMALL AND MEDIUM-SIZED BUSINESSES.
Authors: Attaallah Haneen Ragheb
Published: January 2023

Social Media Marketing is an effective marketing tool that can enhance marketing in Small and Medium-sized businesses (SMEs). Businesses are different in their adaption of new methods, such as social media. The purpose of the paper is to summarize the mentioned factors in the literature that drive social media marketing adoption in SMEs. The paper found that SMEs need more equipped staff. Therefore, studies highly recommended that SMEs design training to transfer the needed skills. Then, to build positive thoughts, companies must increase the interactions between top management, social media, and technology experts. Another factor is the perceived advantages of social media marketing as the lower costs and a broader market. Sometimes SMEs need to gain trust in new technologies due to their fast-moving feature. Therefore, SMEs need to collaborate to mitigate technology constraints. Moreover, stakeholders are essential factors. SMEs need to review their competitors' and suppliers' strategies and consider the preferred platforms by the customers. To adopt social media marketing, SMEs need to make the necessary investment. Studies suggest designating a percentage of the revenue to enhance the online presence. Finally, external factors and industry, such as the need to understand SMEs' needs and type of industry, are essential.

AN IMPROVED SIMPLEC SCHEME FOR FLUID REGISTRATION
Authors: Alahyane Mohamed , Hakim Abdelilah , Laghrib Amine , Raghay Said
Published: January 2023

The image registration is always a strongly ill-posed problem, a stable numerical approach is then desired to better approximate the deformation vectors. This paper introduces an efficient numerical implementation of the Navier Stokes equation in the fluid image registration context. Although fluid registration approaches have succeeded in handling large image deformations, the numerical results are sometimes inconsistent and unexpected. This is related, in fact, to the used numerical scheme which does not take into consideration the different properties of the continuous operators. To take into account these properties, we use a robust numerical scheme based on finite volume with pressure correction. This scheme, which is called by the Semi-Implicit Method for Pressure-Linked Equation-Consistent (SIMPLEC), is known for its stability and consistency in fluid dynamics context. The experimental results demonstrate that the proposed method is more efficient and stable, visually and quantitatively, compared to some classical registration methods.
Random Forests Applied to High-precision Photometry Analysis with Spitzer IRAC
Authors: Krick Jessica E. , Fraine Jonathan , Ingalls Jim , Deger Sinan
Published: January 2023

We present a new method employing machine-learning techniques for measuring astrophysical features by correcting systematics in IRAC high-precision photometry using random forests. The main systematic in IRAC light-curve data is position changes due to unavoidable telescope motions coupled with an intrapixel response function. We aim to use the large amount of publicly available calibration data for the single pixel used for this type of work (the sweet-spot pixel) to make a fast, easy-to-use, accurate correction to science data. This correction on calibration data has the advantage of using an independent data set instead of the science data themselves, which has the disadvantage of including astrophysical variations. After focusing on feature engineering and hyperparameter optimization, we show that a boosted random forest model can reduce the data such that we measure the median of 10 archival eclipse observations of XO-3b to be 1459 ± 200 ppm. This is a comparable depth to the average of those in the literature done by seven different methods; however, the spread in measurements is 30%–100% larger than those literature values, depending on the reduction method. We also caution others attempting similar methods to check their results with the fiducial data set of XO-3b, as we were also able to find models providing initially great scores on their internal test data sets but whose results significantly underestimated the eclipse depth of that planet.

Published: January 2023

We use Keck/NIRSPEC to survey a sample of of young (<1 Gyr), short-period mini-Neptunes orbiting nearby K dwarfs to measure their mass loss via the metastable helium line. We detect helium absorption from all four of the targets in our initial sample. The first detection, around TOI 560b, was announced in a previous paper. We now announce three additional detections around TOI 1430.01, 2076b, and 1683.01. All four planets show an average in-transit excess absorption of 0.7%–1.0%. However, the outflows differ in their kinematic properties. Object TOI 1430b exhibits preingress absorption, while TOI 2076b’s outflow is exceptionally optically thick and shows significant postegress absorption. For all four planets, the width of the measured helium absorption signal is consistent with expectations for a photoevaporative outflow (10–30 km s−1, 5000–10,000 K). Unless broadening mechanisms other than thermal velocity and the bulk outflow velocity are significant, our observations disfavor core-powered mass-loss models, which predict much slower (1–3 km s−1) outflows. We utilize both an isothermal Parker wind model and an order-of-magnitude method to estimate the mass-loss timescale and obtain ∼a few hundred megayears for each planet. We conclude that many, if not all, of these planets will lose their hydrogen-rich envelopes and become super-Earths. Our results demonstrate that most mini-Neptunes orbiting Sun-like stars have primordial atmospheres, and that photoevaporation is an efficient mechanism for stripping these atmospheres and transforming these planets into super-Earths.

Agrowing avenue for determining the prevalence of life beyond Earth is to search for “technosignatures” from extraterrestrial intelligences/agents. Technosignatures require significant energy to be visible across interstellar space and thus intentional signals might be concentrated in frequency, in time, or in space, to be found in mutually obvious places. Therefore, it could be advantageous to search for technosignatures in parts of parameter space that are mutually derivable to an observer on Earth and a distant transmitter. In this work, we used the L-band (1.1–1.9 GHz) receiver on the Robert C. Byrd Green Bank Telescope to perform the first technosignature search presynchronized with exoplanet transits, covering 12 Kepler systems. We used the Breakthrough Listen turboSETI pipeline to flag narrowband hits (∼3 Hz) using a maximum drift rate of ±614.4 Hz s−1 and a signal-to-noise threshold of 5—the pipeline returned ∼3.4 × 105 apparently-localized features. Visual inspection by a team of citizen scientists ruled out 99.6% of them. Further analysis found two signals of interest that warrant follow up, but no technosignatures. If the signals of interest are not redetected in future work, it will imply that the 12 targets in the search are not producing transit-aligned signals from 1.1 to 1.9 GHz with transmitter powers >60 times that of the former Arecibo radar. This search debuts a range of innovative technosignature techniques: citizen science vetting of potential signals of interest, a sensitivity-aware search out to extremely high drift rates, a more flexible method of analyzing on-off cadences, and an extremely low signal-to-noise threshold.
C3 Cluster Clustering Cosmology I. New Constraints on the Cosmic Growth Rate at z ∼ 0.3 from Redshift-space Clustering Anisotropies
Authors: Marulli Federico , Veropalumbo Alfonso , García-Farieta Jorge Enrique , Moresco Michele , Moscardini Lauro , Cimatti Andrea
Published: January 2023

Redshift-space distortions in the clustering of galaxy clusters provide a novel probe to test the theory of gravity on cosmological scales. The aim of this work is to derive new constraints on the linear growth rate of cosmic structures from the redshift-space two-point correlation function of galaxy clusters. We construct a large spectroscopic catalog of optically selected clusters from the Sloan Digital Sky Survey. The selected sample consists of 43,743 clusters in the redshift range 0.1 < z < 0.42, with masses estimated from weak-lensing calibrated scaling relations. We measure the transverse and radial wedges of the two-point correlation function of the selected clusters. Modeling the redshift-space clustering anisotropies, we provide the first constraints on the linear growth rate from cluster clustering. The cluster masses are used to set a prior on the linear bias of the sample. This represents the main advantage in using galaxy clusters as cosmic probes, instead of galaxies. Assuming a standard cosmological model consistent with the latest cosmic microwave background constraints, we do not find any evidence of deviations from general relativity. Specifically, we get the value of the growth rate times the matter power spectrum normalization parameter fσ
8 = 0.44 ± 0.05, at an effective redshift of z = 0.275.
The Galaxy Progenitors of Stellar Streams around Milky Way–mass Galaxies in the FIRE Cosmological Simulations

Published: January 2023

Stellar streams record the accretion history of their host galaxy. We present a set of simulated streams from disrupted dwarf galaxies in 13 cosmological simulations of Milky Way (MW)–mass galaxies from the FIRE-2 suite at z = 0, including seven isolated MW-mass systems and six hosts resembling the MW–M31 pair. In total, we identify 106 simulated stellar streams, with no significant differences in the number of streams and the masses of their progenitors between the isolated and paired environments. We resolve simulated streams with stellar masses ranging from ∼5 × 105 up to ∼109
M
⊙, similar to the mass range between the Orphan and Sagittarius streams in the MW. We confirm that present-day simulated satellite galaxies are good proxies for stellar stream progenitors, with similar properties including their stellar mass function, velocity dispersion, [Fe/H] and [α/H] evolution tracks, and orbital distribution with respect to the galactic disk plane. Each progenitor’s lifetime is marked by several important timescales: its infall, star formation quenching, and stream formation times. We show that the ordering of these timescales is different between progenitors with stellar masses higher and lower than ∼2 × 106
M
⊙. Finally, we show that the main factor controlling the rate of phase mixing, and therefore the rate of fading, of tidal streams from satellite galaxies in MW-mass hosts is the nonadiabatic evolution of the host potential. Other factors commonly used to predict phase-mixing timescales, such as progenitor mass and orbital circularity, show virtually no correlation with the number of dynamical times required for a stream to become phase-mixed.

We present the census of massive (log(M
*/M
⊙) > 11) galaxies at 3 < z < 6 identified over the COSMOS/UltraVISTA Ultra-Deep field stripes: consisting of ≈100 and ≈20 high-confidence candidates at 3 < z < 4 and 4 < z < 6, respectively. The 3 < z < 4 population is comprised of post-starburst, UV-star-forming, and dusty star-forming galaxies in roughly equal fractions, while UV-star-forming galaxies dominate at 4 < z < 6 . We account for various sources of biases in the spectral energy distribution (SED) modeling, finding that the treatment of emission line contamination is essential for understanding the number densities and mass growth histories of massive galaxies at z > 3. The significant increase in observed number densities at z ∼ 4 (> × 5 in ≲600 Myr) implies that this is the epoch at which log(M
*/M
⊙) > 11 galaxies emerge in significant numbers, with stellar ages (≈500–900 Myr) indicating rapid formation epochs as early as z ∼ 7. Leveraging ancillary multiwavelength data sets, we perform panchromatic SED modeling to constrain the total star formation activity of the sample. The star formation activity of the sample is generally consistent with being on the star formation main sequence at the considered redshifts, with ≈15%–25% of the population showing evidence of suppressed star formation rates, indicating that quenching mechanisms are already at play by z ∼ 4. We stack the available Hubble Space Telescope imaging, confirming their compact nature (r

e
≲ 2.2 kpc), consistent with expected sizes of high-z star-forming galaxies. Finally, we discuss how our results are in-line with the early formation epochs and short formation timescales inferred from the fossil records of the most massive galaxies in the universe.
Statistical Analysis of Lunar 1 Hz Waves Using ARTEMIS Observations

Published: January 2023

Like 1 Hz waves occurring in the upstream of various celestial bodies in the solar system, 1 Hz narrowband whistler-mode waves are often observed around the Moon. However, wave properties have not been thoroughly investigated, which makes it difficult to proclaim the generation mechanism of the waves. Using 5.5 yr wave data from ARTEMIS, we perform a detailed investigation of 1 Hz waves in the near-lunar space. The amplitude of lunar 1 Hz waves is generally 0.05–0.1 nT. In the geocentric solar ecliptic coordinates, the waves show no significant regional differentiation pattern but show an absence inside the magnetosphere. Correspondingly, in the selenocentric solar ecliptic coordinates, the waves can occur extensively at ∼1.1–12 RL, while few events are observed in the lunar wake due to a lack of interaction with the solar wind. Furthermore, the wave distributions exhibit modest day–night and dawn–dusk asymmetries but less apparent north–south asymmetry. Compared with the nightside, more intense waves with lower peak wave frequency are present on the dayside. The preferential distribution of 1 Hz waves exhibits a moderate correlation with strong magnetic anomalies. The waves propagate primarily at wave normal angles <60° with an ellipticity of [−0.8, −0.3]. For stronger wave amplitudes and lower latitudes, 1 Hz waves generally have smaller wave normal angles and become more left-hand circularly polarized. Owing to the unique interaction between the Moon and solar wind, our statistical results might provide new insights into the generation mechanism(s) of 1 Hz waves in planetary plasma environments and promote the understanding of lunar plasma dynamics.
High-resolution Spectra of Supernova Remnants in M83

Published: January 2023

In order to better characterize the rich supernova remnant (SNR) population of M83 (NGC 5236), we have obtained high-resolution (∼85 km s−1) spectra of 119 of the SNRs and SNR candidates in M83 with Gemini/GMOS, as well as new spectra of the young SNRs B12-174a and SN 1957D. Most of the SNRs and SNR candidates have [S ii]:Hα ratios that exceed 0.4. Combining these results with earlier studies we have carried out with MUSE and at lower spectroscopic resolution with GMOS, we have confirmed a total of 238 emission nebulae to be SNRs on the basis of their [S ii]:Hα ratios, about half of which have emission lines that show velocity broadening greater than 100 km s−1, providing a kinematic confirmation that they are SNRs and not H ii regions. Looking at the entire sample, we find a strong correlation between velocity widths and the line ratios of [O i] λ6300:Hα, [N ii] λ6584:Hα, and [S ii] λλ6716, 6731:Hα. The density-sensitive [S ii] λ6716:λ6731 line ratio is strongly correlated with SNR diameter, but not with the velocity width. We discuss these results in the context of previously published shock models.
Retour sur les politiques publiques en faveur de l’éducation populaire et de la jeunesse

Published: January 2023

Recouvrant des acceptions diverses, les politiques de jeunesse ont été marquées ces dernières années par un mouvement de multiplication des échelles d’intervention tant au niveau local (municipal, départemental) qu’au niveau européen, et par l’émergence de nouveaux acteurs. Portées au niveau national par la direction de la jeunesse, de l’éducation populaire et de la vie associative, elles visent à favoriser à la fois l’émancipation de la jeunesse, son engagement et sa participation plus large à la vie de la cité. La question de l’égalité des chances est au cœur de cette démarche, avec une forte attention aux publics les plus fragiles ou éloignés des dispositifs.

L’Association des maires d’Île-de-France a demandé à notre collègue Michel Aubouin de conduire une étude sur la violence des jeunes adolescents. Les maires sont en effet confrontés à l’augmentation des incidents graves, pouvant conduire au crime et mettant en cause des jeunes de 13 à 17 ans. L’étude montre qu’une partie des évènements considérés se déroule dans le cadre des « guerres » qu’entretiennent entre eux de nombreux quartiers d’habitat social depuis parfois plusieurs décennies.
Une approche pragmatique et opératoire de la violence à l’école : le climat scolaire
Authors: Fotinos Georges
Published: January 2023

Décider de faire évoluer le climat de son établissement, c’est participer à un projet social et solidaire. Mais c’est aussi, faut-il le rappeler, lutter contre les discriminations, permettre à chaque élève d’exprimer et de développer son potentiel, à chaque enseignant, à chaque chef d’établissement, à chaque personnel d’éducation de vivre pleinement sa vocation professionnelle, son plaisir d’éduquer et de réussir dans son métier. C’est enfin créer les conditions propices à l’exercice de la laïcité, fondatrice du lien social, clef de voûte et moteur de notre école républicaine.
Jeunesse.s engagée.s ?
Authors: Prevost Guillaume
Published: January 2023

Dans le sillage du Service Civique, les dispositifs d’engagement rencontrent un franc succès auprès des jeunes et des associations. Si la dimension militante de cet engagement est réelle, notamment parce qu’elle répond au désir de proximité des jeunes, ce succès souligne aussi les besoins d’insertion, notamment professionnelle, et d’acquisition de compétences que ne délivre pas le système scolaire. Dès lors, la question des plus vulnérables, qui ne disposent pas toujours des ressources pour « s’engager » doit amener à une réflexion sur l’universalité de ces dispositifs, notamment en s’appuyant davantage sur l’école.
L’action d’Energie Jeunes
Authors: Korda Philippe
Published: January 2023

Énergie Jeunes est une association reconnue d’utilité publique, créée en 2009 et agréée par le ministère de l’Éducation nationale. Énergie Jeunes intervient gratuitement partout en France, dans les banlieues et dans les territoires ruraux. Notre combat, c’est la lutte contre les inégalités scolaires. Notre mission, c’est de permettre à tous les élèves d’aimer apprendre. Nous déployons des programmes pédagogiques très innovants, adaptés à chaque année scolaire du CM2 à la troisième, ils sont conçus avec des chercheurs de premier plan dans le domaine des compétences psycho-sociales. Concrètement, les volontaires Énergie Jeunes animent des sessions dans les établissements scolaires, avec la classe entière et avec la participation des professeurs. Chaque année, 120 000 élèves bénéficient de nos programmes. En 55 minutes seulement et trois fois par an, nos interventions génèrent un déclic psychologique chez les élèves. Ces programmes changent des vies. Grâce à une très vaste étude indépendante, on sait aujourd’hui que notre action a un impact direct sur le comportement des jeunes, sur leurs aspirations et même sur leurs résultats scolaires. Et c’est surtout Leila, élève de quatrième, qui nous dit : « Merci, grâce à vous, j’ai compris que j’aimais l’école. »
Jeunes talents : accompagner les viviers d’aujourd’hui pour la fonction publique de demain
Authors: Canivenc Cyprien
Published: January 2023

L’origine sociale, la provenance géographique ou le genre continuent de déterminer les études et les carrières. Tandis que ce constat s’applique notamment aux emplois publics, les actions visant la diversification de la fonction publique répondent à un double impératif de justice sociale et d’efficacité du service public. Dans cette perspective, l’association des anciens élèves de l’ENA et de l’INSP (désormais Servir Alumni) a bâti un continuum d’actions d’égalité des chances au profit des lycéens, des étudiants et des préparationnaires des concours administratifs. Du lycée jusqu’à l’admission aux concours, chaque maillon compte pour susciter, orienter et accompagner les vocations. À l’automne 2022, l’association a créé un dispositif de bourses de 1.000 € au bénéfice des admissibles du concours d’entrée à l’INSP issus des « prépa talents ». Un soutien qui a permis à 15 étudiants talentueux et méritants de se présenter sereinement aux oraux de l’INSP ; cinq d’entre eux ont été admis.
Les promesses du travail international de jeunesse à travers le prisme franco-allemand
Authors: Demesmay Claire
Published: January 2023

Créé en 1963, l’Office franco-allemand pour la Jeunesse (OFAJ) soutient les échanges de jeunes des deux pays, leur permettant de vivre des expériences interculturelles et de développer leur personnalité et leur qualification professionnelle. Pour qu’un plus grand nombre de jeunes puisse bénéficier d’une telle expérience, dont des jeunes ayant moins d’opportunités, l’OFAJ a développé une stratégie « Diversité et Participation ». A cette fin, il s’appuie sur son expertise interculturelle et promeut des méthodes d’animation adaptées.
L’appropriation différenciée du contrôle par les résultats à Pôle emploi
Authors: Gilbert Patrick , Gurtner Emmanuelle , Soulerot Marion
Published: January 2023

Le contrôle par les résultats, compagnon organique du nouveau management public, se met en place en soulevant bien des difficultés, ce qui en fait l’objet de diverses critiques. Certains évoquent les classiques résistances individuelles au changement, sources de transgressions, et d’autres l’incompatibilité supposée du contrôle par les résultats avec les missions de service public. À l’écart de ces débats, l’article entend témoigner qu’une conformité trop grande au contrôle formel peut nuire à la performance, alors que certaines formes de transgression y contribuent. Les auteurs appuient leur argumentation sur une étude qualitative conduite à Pôle Emploi (une analyse documentaire, 77 entretiens individuels et 10 entretiens collectifs réalisés dans 10 des agences d’une grande région). L’analyse des résultats prenant en compte les contextes locaux (les agences) et les particularités situationnelles montre les effets contrastés des comportements dans l’appropriation d’un outil de contrôle par les résultats. La théorie de la régulation sociale aide à comprendre comment se construisent les attitudes à l’égard de l’introduction d’un système de pilotage par les résultats. L’article témoigne alors de l’importance de l’animation managériale dans l’appropriation d’un outil de contrôle.
Le processus de normalisation de l’audit : état de l’art et voies de recherches futures
Authors: Fabioux Isabelle
Published: January 2023

L’objet de cet article est de proposer une synthèse des travaux ayant porté sur le processus de normalisation de l’audit et de faire ressortir les voies de recherches sur les aspects partiellement ou non encore explorés. La revue de littérature est structurée en deux volets. Un premier volet s’attache aux participants à la normalisation de l’audit, leur typologie, composition et évolution. Le second volet appréhende le processus normatif à travers les objectifs poursuivis et les écueils constatés. Il met également en exergue la place centrale du due process . La mise en perspective des travaux antérieurs dresse les contours de la connaissance académique sur le processus méconnu de normalisation de l’audit et permet d’ouvrir cet état de l’art sur des pistes de recherches futures.

Sur les pas de Zoran Music. Lieux du traumatisme et lieux de création
Authors: Maître-Lewy-Bertaut Isabelle
Published: January 2023

Le traumatisme vécu à Dachau, malgré l’effroi, ne détruit pas le peintre Zoran Music. Son œuvre exprime le triomphe de l’art sur la destructivité, grâce au travail psychique : représenter, refouler, laisser en latence, répéter, élaborer, sublimer en boucles successives qui mènent à un haut niveau la représentation et le chemin de l’éthique.
Le côté sombre de l’institution de la psychanalyse, de Sigmund Freud et de ses successeurs
Authors: Stora Jean-Benjamin
Published: January 2023

Cet article traite du destin tragique du grand psychanalyste Sándor Ferenczi qui a été persécuté par l’institution psychanalytique parce qu’il pensait différemment à partir de l’observation de la clinique des patients qui n’étaient pas des névrosés classiques et qui n’étaient pas des patients borderline. Le problème posé est celui de penser différemment dans une institution psychanalytique dominée par l’idéologie. Pierre Marty dans les années 1950 et 1960 fut confronté au même problème, mais il a réussi à créer l’École de Paris et l’Institut de psychosomatique.
Sur l’aveugle résistance des rêves
Authors: Agnel Aimé
Published: January 2023

« L’histoire du rêve reste encore à écrire », note Walter Benjamin dans son livre sur les rêves. Sa position est respectueuse mais critique à l’égard de Freud. Le rêve, pense-t-il, ne comporte aucun déguisement, il a en revanche un « caractère secret » qu’il convient de protéger. Nul besoin de faire appel à un contenu latent qui résoudrait l’énigme du rêve. Le sens du rêve est la rencontre que le moi peut faire de lui-même « comme il lui est impossible de le faire dans la vie éveillée ». Marguerite Yourcenar témoigne, dans un registre proche, d’une compréhension poétique du rêve. Le dormeur, écrit-elle « assemble des images comme le poète assemble des mots : il en use avec plus ou moins de bonheur pour parler de soi à soi-même ». Les rêves recueillis entre 1930 et 1939 par Charlotte Beradt s’opposent encore plus nettement à l’interprétation freudienne. Ils ne renvoient pas au passé des rêveurs mais à la contrainte et à la domination nazies qui sont en train de s’établir en Allemagne. Les rêveurs, note-t-elle, « ne sont pas confrontés à des conflits de leur vie privée mais à ceux dans lesquels les a plongés l’espace public ». Ce n’est pas non plus l’interprétation freudienne qui peut rendre compte des rêves d’hommes noirs notés par Franz Fanon. Soigner la névrose de ces patients conduit à « transformer les structures sociales ». Parmi les analystes dissidents critiquant l’interprétation freudienne d’un point de vue non directement politique mais ouvert au social, Alfred Adler et Carl G. Jung apportent un complément utile en mettant l’accent sur le complexe d’infériorité et la volonté de puissance, pour le premier, et la dynamique archétypique, la compensation et le jeu des contraires pour le second.
Naama et le tissage
Authors: Fourgeaud Catherine
Published: January 2023

Naama, la femme de Noé, inventeuse selon certains du tissage, est une figure mythique intéressante : à sa suite nous verrons que le tissage est une activité très symbolique du féminin sous ses différents aspects. Mais le sort réservé à Naama est représentatif des aléas de la reconnaissance des femmes, et de leur apport à la civilisation. On ne peut qu’insister sur la nécessité d’intégrer les valeurs du féminin à notre monde contemporain.
Outils de gestion et dynamiques formatives de l’ESS
Authors: Demoustier Danièle
Published: January 2023

Fortement marquée par une culture de métier et d’éducation populaire, l’économie sociale et solidaire a développé ses propres démarches d’évaluation interne, depuis les années 1960, à la fois comme outils de gestion et de prospective, et comme démarche pédagogique de mobilisation des membres. Assez précocement par rapport à la rse , ses instances ont associé les différentes organisations à une réflexion plus large sur l’élaboration de processus d’évaluation de leur impact sociétal, afin de spécifier le rôle de l’ESS dans les modes de certification institutionnalisés et de mieux mettre en évidence son utilité sociale et sa contribution aux dynamiques formatives.
Rêves traumatiques et cultures : la place des figures culturelles du traumatique
Authors: Di Charles , Khiar Zerrouk Assia , Bailly Julie , Baubet Thierry , Moro Marie Rose
Published: January 2023

Cet article cherche à montrer ce que le rêve traumatique doit à la culture. Il s’appuie sur l’analyse psychanalytique et anthropologique de trois rêves traumatiques rapportés par un patient migrant dans une consultation transculturelle. Nous savons que le trauma est influencé par la culture et cherchons à montrer que les rêves traumatiques le sont aussi. C’est ce que nous nommons figures culturelles du rêve traumatique . Ces dernières offrent de nouvelles perspectives à l’interprétation des rêves traumatiques des patients migrants.
Le lien mère-enfant dans la protection de l’enfance à l’épreuve du trauma
Authors: Fernández De Soto Vanessa , Titia Rizzi Alice
Published: January 2023

Pour les femmes accueillies dans une structure de la protection de l’enfance, devenir mère demande un accordage entre un passé traumatique et un système de prévention précoce. La maternité actualise tant les appartenances culturelles et familiales que les ruptures. Lorsque la mère est accablée par les violences subies lors de l’immigration, par la solitude et les reviviscences post-traumatiques, le lien de la dyade se fragilise et c’est l’enfant qui s’exprime. Nous mettrons en lumière grâce à une vignette clinique des mécanismes de restauration du trauma délégués à l’enfant. Écouter la souffrance de l’enfant et accorder une place aux compétences maternelles permet d’en limiter les effets néfastes. La réparation se matérialise lorsque les espaces pour chaque membre de la dyade sont différenciés. Les ressources mobilisées par la famille favorisent l’élaboration de leur histoire et la construction de leur avenir.
