O ENSINO COMO ATO DE RESISTÊNCIA EM DIÁRIO DE ESCOLA
Authors: SOUZA Anderson Ibsen Lopes de , BARBOSA Raquel Lazzari Leite
Published: October 2019

O presente estudo aborda a obra Diário de escola, do escritor francês Daniel Pennac, a partir de um viés crítico embasado à luz dos conceitos de globalização e de pós-modernidade, onde confrontamos tais conceitos ideológicos com os paradoxos da educação na atualidade, tudo no intuito de verificar a possibilidade de se trabalhar o ensino como ato de resistência. Nesse romance de teor autobiográfico, que traz a figura de um bem-sucedido professor que fora um aluno problemático e com dificuldade de aprendizagem, Pennac demonstra que a escola tradicional apenas reproduz a ordem social hegemônica, abandonando aqueles jovens que não conseguem se adaptar ao sistema. Apesar de a escola muitas vezes querer transformar os alunos em meros indivíduos, há ainda aqueles professores que buscam salvar os alunos do “afogamento”; e são estes magistrados revolucionários que podem livrar os “lerdos emblemáticos” desse sistema inexorável, que cria no microcosmo escolar uma separação social. É assim que Pennac sugere que a educação escolar seja um ato de resistência contra esse sistema opressor, para que o universo escolar, ao invés de vaticinar o sucesso ou o fracasso dos jovens que lá buscam, se torne um ambiente propício ao desenvolvimento das potencialidades de cada estudante.

Published: October 2019

Os avanços tecnológicos e o aumento do poder de consumo têm resultado em uma maior produção de resíduos, evidenciando a importância do processo de reciclagem. A atividade dos catadores de materiais recicláveis pode ocorrer tanto de forma individual, como organizada em cooperativas. Embora de grande importância no que tange a um ciclo sustentável de produção, a atividade dos catadores sofre com dificuldades nas mais variadas esferas, seja econômica, social e cultural. O presente artigo apresenta uma revisão bibliográfica dos artigos publicados no Brasil, no período de 2004 a 2014, a respeito da atividade de catadores de materiais recicláveis.

UNA EDUCACIÓN DE CALIDAD PARA UNA DEMOCRACIA PARTICIPATIVA
Authors: GARCÍA-RUBIO Juan
Published: October 2019

En este artículo se aborda la importancia de la educación para que cualquier país disfrute de una democracia verdaderamente participativa, que no consista únicamente en la emisión del voto ciudadano cada un cierto tiempo. Sin embargo, no nos sirve cualquier educación, se necesita una educación de calidad que ayude a comprender de una forma crítica y reflexiva nuestro mundo. Una educación de calidad con tres dimensiones clave que analizamos: equidad, pertinencia y relevancia. La escuela debe contribuir a transmitir entre los jóvenes valores esenciales en democracia como el diálogo, el acuerdo, la convivencia y el respeto a las opiniones opuestas. A su vez, una democracia participativa favorecerá la existencia de una educación de calidad que alcance a todos los ciudadanos, sin excepción. La educación y la democracia se necesitan mutuamente, y ambas se refuerzan

O lobo-guará, Chrysocyon brachyurus (Carnivora, Canidae), possui altíssimo valor biológico, em virtude de ser considerada espécie vulnerável à extinção, principalmente pela eliminação sistemática de seu habitat. Paralelamente, em cativeiro tem-se tido dificuldade na reprodução, manutenção, bem como na criação dos filhotes nascidos, devido a deficiências no manejo e problemas de doenças. O presente estudo retrospectivo de 30 anos, relaciona as principais alterações ocorridas com 100 animais (59,41, O) entre filhotes e jovens (20 animais) e adultos (80 animais) mantidos no Zoológico de São Paulo. Como resultado obtiveram-se lII processos: gastrointestinais, 62,0%; traumáticos, 13,6%; respiratório, 8,2%; urinários, 8,2%, circulatórios, 4,5%; além de casos isolados. Os sinais clínicos mais comumente observados referiram-se aos processos gastrentéricos representados por diarréia, vômito, anorexia, e prostração. Das principais enfermidades bacterianas prevaleceram a leptospirose, salmonelose e colibacilose. Decreve-se primeiro relato de surto de parvovirose no Brasil, que levou à morte 11 dos 17 animais atingidos. Dentre os parasitos prevaleceram Ancylostoma sp, Trichuris sp e coccídeos. Salientam-se 6 casos de parasitose renal por Dioctophyme renale. Os processos traumáticos foram representados, principalmente, por infantofagia cometida pelos pais. Para lobos-guarás em cativeiro deve-se ter especial cuidado com as enfermidades do aparelho gastrointestinal, em virtude de apresentarem alterações de etiologia variada como bacterianas, virais, verminóticas, por distúrbios alimentares e em decorrência do estresse em cativeiro.

Virtual ou não: eis a questão! – conceitos fundamentais para a (des) construção de um museu dito “virtual”
Authors: Brisa Zamana
Published: October 2019

This study addresses some of the ideas developed in the Master's dissertation entitled "Museum of the High Sertão of Bahia: dialogues between museum of territory and digital cultures" in which it is argued that Museology entails a multidisciplinary approach on memory and heritage. Therefore, the museum, which is also and especially the object of study of Museology, for all that it is, must attend to the growing discourse of digital cultures. In this scenario, the Internet, a fruitful mode of communication, has reshaped the structural bases of the so-called digital culture expressed in a large network of connections in "nodes" that intertwine in what can be called cyberspace. And due to social and technological changes, it is proposed the dialogue between new ICTs and museums, highlighting the similarities and intercessions that may contribute or reflect positively to possible changes in society. It is known that common sense that limits or falsely and mistakenly associates the virtual way of doing something eminently linked to the Internet or lack of materiality. However, the term "virtual" as "power" has almost nothing to do with the common sense.

Keywords: museology, virtual, digital, common sense.
Os lugares de memória da ditadura: disputas entre o poder público e os movimentos sociais
Authors: Ferraz Joana DArc , Campos Lucas
Published: October 2019

The sites of memory, in Pierre Nora's perspective (1993), are spaces of eternalization of a memory's group that can no longer be spontaneously evoked by collective memory. There is a large dispute between the State and the social movements regarding the preservation of historical heritage that alludes to the Brazilian military-business coup (1964-1985) in Rio de Janeiro. We intend to think the political place of these sites of memories, consulting the patrimony of spaces and buildings which advocate for the coup and dictatorship, in the city of Rio de Janeiro. The policy that has been practiced so far by the State can be defined as conciliatory. However, the social movements demand the insertion of their voices in these places, considering them, silenced or forgotten. We are interested in analyzing these disputes and how they reflect on society.

Key words: Brazilian military-business dictatorship; memory; patrimony.

The Association of Southeast Asian Nations (ASEAN) is an organization of countries in Southeast Asia established in Bangkok, Thailand, on August 8, 1967 under the Bangkok Declaration by Indonesia, Malaysia, Philippines, Singapore, and Thailand. For more th an five decades ASEAN has experienced many positive and significant developments towards a more integrative and forward - looking stage with the establishment of an ASEAN Community by 2015.  The ASEAN Community not only affects the economic sector, but also other sectors, including "education" as an effort to build competitive human resources. The ASEAN Economic Community (AEC) challenges in education that will be faced are the proliferation o f foreign educational institutions, standardization of orientation in education, which is pro - market, and markets labor that will be flooded by foreign workers. Therefore, the era of ASEAN free trade should be welcomed by the world of education quickly, so that the human resources (HR) of Indonesia, especially by women who still have low resource. They should be prepared for facing an intense competition with other countries.  ASEAN countries have considered synchronizing the certification standards, streng thening, and improving the skills and knowledge of ASEAN youth and women in the regional integration process. Therefore, ASEAN countries have always been active in encouraging cooperative relations in various levels of education and training, at the same t ime encouraging all organizations and schools in each country to seek cooperation partners in other countries of the ASEAN region.

Most dynamically confirmed stellar-mass black holes (BHs) and their candidates were originally selected from X-ray outbursts. In the present work, we search for BH candidates in the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey using the spectra along with photometry from the All Sky Automated Survey for SuperNovae (ASAS-SN), where the orbital period of the binary may be revealed by the periodic light curve, such as the ellipsoidal modulation type. Our sample consists of nine binaries, where each source contains a giant star with large radial velocity variation (

) and periods known from light curves. We focus on the nine sources with long periods (T
ph > 5 days) and evaluate the mass M
2 of the optically invisible companion. Since the observed ΔV
R from only a few repeating spectroscopic observations is a lower limit of the real amplitude, the real mass M
2 can be significantly higher than the current evaluation. It is likely an efficient method to place constraints on M
2 by combining ΔV
R from LAMOST and T
ph from ASAS-SN, particularly by the ongoing LAMOST Medium Resolution Survey.
Entropy Rain: Dilution and Compression of Thermals in Stratified Domains
Authors: Anders Evan H. , Lecoanet Daniel , Brown Benjamin P.
Published: October 2019

Large-scale convective flows called giant cells were once thought to transport the Sun’s luminosity in the solar convection zone, but recent observations have called their existence into question. In place of large-scale flows, some authors have suggested the solar luminosity may instead be transported by small droplets of rapidly falling, low-entropy fluid. This “entropy rain” could propagate as dense vortex rings, analogous to rising buoyant thermals in the Earth’s atmosphere. In this work, we develop an analytical theory describing the evolution of dense, negatively buoyant thermals. We verify the theory with 2D cylindrical and 3D Cartesian simulations of laminar, axisymmetric thermals in highly stratified atmospheres. Our results show that dense thermals fall in two categories: a stalling regime in which the droplets slow down and expand, and a falling regime in which the droplets accelerate and shrink as they propagate downwards. We estimate that solar downflows are in the falling regime and maintain their entropy perturbation against diffusion until they reach the base of the convection zone. This suggests that entropy rain may be an effective nonlocal mechanism for transporting the solar luminosity.
A Survey of Magnetic Field Strengths in the Envelopes of Molecular Clouds via the 18 cm OH Zeeman Effect
Authors: Thompson K. L. , Troland T. H. , Heiles C.
Published: October 2019

We present the results of an extensive Arecibo observational survey of magnetic field strengths in the inter-core regions of molecular clouds to determine their role in the evolution and collapse of molecular clouds as a whole. Sensitive 18 cm OH Zeeman observations of absorption lines from Galactic molecular gas in the direction of extragalactic continuum sources yielded 38 independent measurements of magnetic field strengths. Zeeman detections were achieved at the 3σ level toward nine clouds, while the others revealed sensitive upper limits to the magnetic field strength. Our results suggest that total field strengths in the inter-core regions of giant molecular clouds (GMCs) are about 15 μG.
Preflare Processes, Flux Rope Activation, Large-scale Eruption, and Associated X-class Flare from the Active Region NOAA 11875
Authors: Mitra Prabir K. , Joshi Bhuwan
Published: October 2019

We present a multiwavelength analysis of the eruption of a hot coronal channel associated with an X1.0 flare (SOL2013-10-28T02:03) from the active region NOAA 11875 by combining observations from Atmospheric Imaging Assembly/Solar Dynamics Observatory (SDO), Helioseismic and Magnetic Imager/SDO, Reuven Ramaty High Energy Solar Spectroscopic Imager, and Hiraiso Radio Spectrograph. EUV images at high coronal temperatures indicated the presence of a hot channel at the core of the active region from the early preflare phase evidencing the preexistence of a quasi-stable magnetic flux rope. The hot channel underwent an activation phase after a localized and prolonged preflare event occurring adjacent to one of its footpoints. Subsequently, the flux rope continued to rise slowly for ≈16 minutes during which soft X-ray flux gradually built-up characterizing a distinct precursor phase. The flux rope transitioned from the state of slow rise to the eruptive motion with the onset of the impulsive phase of the X1.0 flare. The eruptive expansion of the hot channel is accompanied by a series of type III radio bursts in association with the impulsive rise of strong hard X-ray nonthermal emissions that included explicit hard X-ray sources of energies up to ≈50 keV from the coronal loops and ≈100 keV from their footpoint locations. Our study contains evidence that preflare activity occurring within the spatial extent of a stable flux rope can destabilize it toward eruption. Moreover, sudden transition of the flux rope from the state of slow rise to fast acceleration precisely bifurcated the precursor and the impulsive phases of the flare, which points toward a feedback relationship between early coronal mass ejection dynamics and the strength of the large-scale magnetic reconnection.
Radio Spectroscopic Imaging of a Solar Flare Termination Shock: Split-band Feature as Evidence for Shock Compression
Authors: Chen 陈 Bin 彬 , Shen 沈呈 Chengcai 彩 , Reeves Katharine K. , Guo 郭 Fan 帆 , Yu 余思 Sijie 捷
Published: October 2019

Solar flare termination shocks have been suggested as one of the promising drivers for particle acceleration in solar flares, yet observational evidence remains rare. By utilizing radio dynamic spectroscopic imaging of decimetric stochastic spike bursts in an eruptive flare, Chen et al. found that the bursts form a dynamic surface-like feature located at the ending points of fast plasma downflows above the looptop, interpreted as a flare termination shock. One piece of observational evidence that strongly supports the termination shock interpretation is the occasional split of the emission band into two finer lanes in frequency, similar to the split-band feature seen in fast-coronal-shock-driven type II radio bursts. Here, we perform spatially, spectrally, and temporally resolved analysis of the split-band feature of the flare termination shock event. We find that the ensemble of the radio centroids from the two split-band lanes each outlines a nearly co-spatial surface. The high-frequency lane is located slightly below its low-frequency counterpart by ∼0.8 Mm, which strongly supports the shock-upstream–downstream interpretation. Under this scenario, the density compression ratio across the shock front can be inferred from the frequency split, which implies a shock with a Mach number of up to 2.0. Further, the spatiotemporal evolution of the density compression along the shock front agrees favorably with results from magnetohydrodynamics simulations. We conclude that the detailed variations of the shock compression ratio may be due to the impact of dynamic plasma structures in the reconnection outflows, which results in distortion of the shock front.
On Kinetic Instabilities Driven By Ion Temperature Anisotropy and Differential Flow in the Solar Wind
Authors: Sun Heyu , Zhao Jinsong , Xie Huasheng , Wu Dejin
Published: October 2019

The ion temperature anisotropy instability is widely thought of as a constraint on the distribution of the ion perpendicular and parallel temperatures in the solar wind. Besides the ion temperature anisotropy, proton and alpha particle beams are permeating in the solar wind. Therefore, this paper presents a comprehensive investigation on unstable waves resulting from both ion temperature anisotropy and ion beams. It finds that the strongest electromagnetic cyclotron instability triggers the left-hand circularly polarized Alfvén/proton-cyclotron wave propagating along the background magnetic field. The strongest fast-magnetosonic/whistler firehose instability generates the right-hand circularly polarized fast-magnetosonic/whistler wave propagating reversely to the background magnetic field. The mirror instability preferably drives oblique mirror mode waves with two anticorrelated perpendicular magnetic components. The Alfvén firehose instability is prior to generating oblique Alfvén waves with two unbalanced perpendicular magnetic components that are nearly positive-correlated. Due to the effects of streaming proton and alpha particles, both the mirror and Alfvén firehose instabilities produce slowly propagating unstable waves in comparison to nonpropagating waves in motionless plasmas. The differential proton and alpha particle flows result in the ion/ion beam instability, destabilizing obliquely propagating Alfvén/proton-cyclotron waves. The ion/ion beam instability can provide a constraint on electromagnetic fluctuations in the low-beta region. Moreover, this paper clearly explores the dependence of the frequency and electromagnetic polarization on the normal angle for each kind of instability, which could be useful for distinguishing the instability mechanism in the solar wind.
The Effect of the Approach to Gas Disk Gravitational Instability on the Rapid Formation of Gas Giant Planets
Authors: Boss Alan P.
Published: October 2019

Observational evidence suggests that gas disk instability may be responsible for the formation of at least some gas giant exoplanets, particularly massive or distant gas giants. With regard to close-in gas giants, Boss used the β cooling approximation to calculate hydrodynamical models of inner gas disk instability, finding that provided disks with low values of the initial minimum Toomre stability parameter (i.e., Q

i
 < 2 inside 20 au) form, fragmentation into self-gravitating clumps could occur even for β as high as 100 (i.e., extremely slow cooling). Those results implied that the evolution of disks toward low Q

i
must be taken into account. This paper presents such models: initial disk masses of 0.091 M
⊙ extending from 4 to 20 au around a 1 M
⊙ protostar, with a range (1–100) of β cooling parameters, the same as in Boss, but with all the disks starting with Q

i
 = 2.7, i.e., gravitationally stable, and allowed to cool from their initial outer disk temperature of 180 K to as low as 40 K. All the disks eventually fragment into at least one dense clump. The clumps were again replaced by virtual protoplanets (VPs) and the masses and orbits of the resulting ensemble of VPs compare favorably with those of Boss, supporting the claim that disk instability can form gas giants rapidly inside 20 au, provided that sufficiently massive protoplanetary disks exist.

Current helicity, H

c
, and magnetic helicity, H

m
, are two main quantities used to characterize magnetic fields. For example, such quantities have been widely used to characterize solar active regions and their ejecta (magnetic clouds). It is commonly assumed that H

c
and H

m
have the same sign, but this has not been rigorously addressed beyond the simple case of linear force-free fields. We aim to answer whether H

m

H

c
 ≥ 0 in general, and whether it is true over some useful set of magnetic fields. This question is addressed analytically and with numerical examples. The main focus is on cylindrically symmetric straight flux tubes, referred to as flux ropes (FRs), using the relative magnetic helicity with respect to a straight (untwisted) reference field. Counterexamples with H

m

H

c
 < 0 have been found for cylindrically symmetric FRs with finite plasma pressure, and for force-free cylindrically symmetric FRs in which the poloidal field component changes direction. Our main result is a proof that H

m

H

c
 ≥ 0 is true for force-free cylindrically symmetric FRs where the toroidal field and poloidal field components are each of a single sign, and the poloidal component does not exceed the toroidal component. We conclude that the conjecture that current and magnetic helicities have the same sign is not true in general, but it is true for a set of FRs of importance to coronal and heliospheric physics.

We present a systematic search for periodically varying quasar and supermassive black hole binary (SMBHB) candidates in the Pan-STARRS1 Medium Deep Survey (MDS). From ∼9000 color-selected quasars in an ∼50 °2 sky area, we initially identify 26 candidates with more than 1.5 cycles of variation. We extend the baseline of observations via our imaging campaign with the Discovery Channel Telescope and the Las Cumbres Observatory network and reevaluate the candidates using a more rigorous, maximum likelihood method. Using a range of statistical criteria and assuming the damped random walk model for normal quasar variability, we identify one statistically significant periodic candidate. We also investigate the capabilities of detecting SMBHBs with the Large Synoptic Survey Telescope using our study with MDS as a benchmark and explore any complementary multiwavelength evidence for SMBHBs in our sample.
AGN-Driven Outflows in Dwarf Galaxies

Published: October 2019

We present spatially resolved kinematic measurements of active galactic nucleus (AGN)-driven outflows in dwarf galaxies in the stellar mass range ∼6 × 108–9 × 109
M
⊙, selected from SDSS DR7 and DR8 and followed-up with Keck/LRIS spectroscopy. We find spatially extended (∼1 half-light radius), high-velocity ionized gas outflows (W
80 up to ∼2000 km s−1) in 13/50 dwarf galaxies with and without an AGN. Outflow velocities in all 13 galaxies exceed the escape velocities of their halos. Nine of these 13 galaxies are classified as AGNs according to their narrow line flux ratios. Of these, six have outflow components with emission-line ratios consistent with AGN ionization. Although black holes (BHs) have been known to populate the centers of at least a few dwarf galaxies and indirect evidence of AGN quenching of star formation in dwarfs has begun to surface, our measurements constitute the first direct detection and measurement of AGN impact on the large-scale kinematics and gas content in dwarf galaxies. Furthermore, we find evidence suggestive of ongoing star formation suppression, possibly regulated by the AGN. Galaxy formation models must therefore be able to account not only for the formation and growth of BHs at the centers of dwarf galaxies, but should also be revised to include AGNs as important—and perhaps dominant—sources of feedback in low-mass galaxies.

We studied the spatial distributions of multiple stellar populations (MPs) in a sample of 20 globular clusters (GCs) spanning a broad range of dynamical ages. The differences between first-population (FP) and second-population (SP) stars were measured by means of the parameter A
+, defined as the area enclosed between their cumulative radial distributions. We provide the first purely observational evidence of the dynamical path followed by MPs from initial conditions toward a complete FP–SP spatial mixing. Less dynamically evolved clusters have SP stars more centrally concentrated than FPs, while in more dynamically evolved systems the spatial differences between FP and SP stars decrease and eventually disappear. By means of an appropriate comparison with a set of numerical simulations, we show that these observational results are consistent with the evolutionary sequence expected by the long-term dynamical evolution of clusters forming with an initially more centrally concentrated SP subsystem. This result is further supported by the evidence of a trend between A
+ and the stage of GC dynamical evolution inferred by the ratio between the present-day and the initial mass of the cluster.

TheBrachionus plicatiliscomplex represents the most studied group of rotifers, although the systematics of the species complex has not been completely clarified. Many studies have been conducted trying to explore the diversity within the complex, leading to the recognition of three major morphotypes: large (L), small-medium (SM), and small (SS). Currently six species have been described and classified under these types and another nine taxa have been identified but not formally described. Within the L group, three species have been officially described [B. plicatiliss.s. (L1),B. manjavacas(L2), andB. asplanchnoidis(L3)], while a formal description of L4, unofficially known asB.‘Nevada’, is still lacking. In the present study, a new species,Brachionus paranguensissp. nov., is formally described and presented as a representative of the L4 clade. The species has been named after a high altitude saline crater lake from Central Mexico, where the specimens were collected. An integrated approach using DNA taxonomy through COI and ITS1 markers, morphology, and ecology was used to confirm the identity of the new species.

Multiple paternity was demonstrated for seven clutches of eggs and 40 offspring sampled from these clutches in the cuttlefishSepiella japonicafrom Fujian Shacheng Harbor Cultivation Base (Fujian Province, China), using four microsatellite DNA markers. It was observed that female cuttlefish copulated with different males. In this study, genotyping data suggest that at least three paternal allele genotypes were present in all seven clutches indicating that at least two males were responsible for each brood. Combined with behavioral observations, this study provides evidence for sperm competition and multiple paternity inS. japonica.
Les associations culturelles : état des lieux et typologie
Authors: Rathle Jean-Philippe
Published: October 2019

En 2013, on compte 1,3 million d’associations en France, dont une sur cinq déclare une activité culturelle, soit 263 400 associations. Près de 100 000 associations culturelles (37 % de l’ensemble) œuvrent dans le domaine du spectacle vivant, 65 000 dans les arts visuels et l’écriture (lieux d’exposition, ateliers et collectifs d’artistes), 50 000 dans l’animation socioculturelle, 35 000 dans le patrimoine et 15 000 dans l’enseignement artistique et culturel. 16 % des associations culturelles ont recours à l’emploi salarié et l’ensemble des associations culturelles mobilisent 3,5 millions de bénévoles. On estime à 200 000 le nombre de salariés dans les associations culturelles, soit 77 000 en équivalent temps plein, car les trois quarts d’entre eux sont employés à temps partiel, et 60 % sous contrat à durée indéterminée. L’ensemble des associations culturelles disposent de ressources courantes de 7,1 milliards d’euros, dont 84 % sont concentrées dans les associations employeuses. Parmi les 43 300 associations culturelles employeuses, les disparités d’organisation et de fonctionnement sont importantes. L’étude dégage quatre profils d’associations, aux caractéristiques très différentes : les associations dédiées au spectacle vivant (46 %), celles dédiées à l’animation et à l’éducation artistique et culturelle (33 %), aux arts visuels et à l’écriture (11 %) et au patrimoine (9 %).

Au cours de l’année 2017-2018, trois élèves sur quatre ont été touchés par au moins une action ou un projet relevant de l’éducation artistique et culturelle ( eac ) : 82 % dans le premier degré et 62 % dans les collèges. Les disparités de l’offre en matière d’action ou de projet sont en partie liées aux caractéristiques des établissements scolaires, notamment à l’ancienneté moyenne des enseignants. En éducation prioritaire, la part d’élèves touchés par les actions ou projets est moindre, respectivement 78 % en école et 55 % en collège. Les différences entre établissements sont également liées à l’organisation de l’éducation artistique et culturelle et à la présence d’un coordinateur de l’éducation artistique et culturelle (dont sont dotées plus de deux écoles sur cinq) ou d’un référent eac (présents dans deux tiers des collèges). Outre les actions et projets d’éducation artistique et culturelle, près de 100 % des écoles et des collèges organisent au moins une activité en lien avec l’éducation artistique et culturelle (sortie culturelle, rencontre avec un artiste, etc.). Dans trois écoles sur quatre et dans plus de neuf collèges sur dix, au moins une activité est réalisée en partenariat avec une structure culturelle. Enfin, au cours de l’année 2017-2018, la chorale est présente dans 56 % des écoles et 84 % des collèges.
Violence psychologique, implication organisationnelle et transfert des connaissances : le cas des seniors
Authors: Giraud Laurent , Chouki Mourad , Frimousse Soufyane , Gannouni Kais
Published: October 2019

L’objectif de cette recherche est d’étudier les effets de la violence psychologique sur le transfert des connaissances à travers l’implication organisationnelle, en particulier chez les seniors. Un modèle d’équations structurelles a permis de tester nos hypothèses sur des données récoltées auprès de 270 salariés bancaires travaillant en Tunisie. Nos résultats confirment que la violence psychologique (dimension santé) affecte négativement le transfert des connaissances via l’implication organisationnelle (affective et normative). Pour les seniors, l’impact de la violence psychologique est plus fort et l’effet sur le transfert des connaissances s’exerce seulement à travers l’implication normative. Nos résultats complètent les modèles de gestion des connaissances existants en confirmant la pertinence d’y inclure l’implication organisationnelle et la violence psychologique. Afin d’améliorer le transfert des connaissances, les managers sont invités à nourrir l’implication et à réduire la violence psychologique dans leur organisation.
