Published: August 2021

The electrochemical reduction process of ZnFe2O4 in NaCl-CaCl2 melts was studied. Thermodynamic analysis shows that the reduction process of ZnFe2O4 is carried out in multiple steps, and it is difficult to reduce Fe3+ to Fe in one step. Electrochemical tests revealed that the reduction process of ZnFe2O4 includes three steps: First, Fe3+ is reduced to Fe in two steps, then Zn2+ is reduced to Zn in one step. The reduction of Fe3+ on the Mo electrode is a reversible process controlled by diffusion, while the reduction of Zn2+ is an irreversible process controlled by diffusion. The influence of electrolysis voltage and temperature on the process of electric deoxidation has also been studied. It is indicated that properly increasing the temperature is conducive to the diffusion of oxygen ions, thereby increasing the deoxidation rate. With the gradual increase of voltage, the reduction process of ZnFe2O4 is ZnFe2O4 → FeO + ZnO → Fe + ZnO → Fe + Zn.

В статье исследованы возможности сетевого взаимодействия образовательных организаций высшего и общего образования в психолого-педагогической коррекции поведения учащихся с различными формами проявления социальной девиации на основе социально-ориентированного проекта физкультурно-спортивной деятельности, реализуемого студентами педагогического вуза под руководством педагогов-методистов. Педагогическое исследование было организовано на базе педагогического вуза и базовых школ педагогических практик студентов факультета физической культуры и спорта. Результаты исследования свидетельствуют о том, что сетевая форма позволяет интегрировать материально-технические, интеллектуальные, воспитательные ресурсы вуза и школы и обеспечивает большую эффективность превентологической работы с девиантными учащимися. Авторами отмечено, что проблема коррекции поведения девиантных подростков является комплексной, в решении которой должны взаимодействовать социальные педагоги, психологи, классные руководители, специалисты физической культуры и спорта, муниципальных органов управления образованием и учреждений внутренних дел. Определены условия эффективности дальнейшей реализации сетевого взаимодействия «вуз - школа» в коррекции поведения девиантных учащихся средствами физкультурно-спортивной деятельности. Результаты исследования представляют профессиональный интерес для учителей физической культуры, социальных педагогов, психологов.
The article examines the potential of network interaction of educational organizations of higher and general education in the psychological and pedagogical correction of students’ behavior with various forms of social deviation on the basis of a socially-oriented project of physical culture and sports activities implemented by students of a pedagogical university under the guidance of methodologists. The pedagogical research was held on the basis of the pedagogical university and the basic schools of pedagogical practices of students of the Faculty of Physical Culture and Sports. The results of the study indicate that the network form allows integrating the material, technical, intellectual, and educational resources of the university and school and provides greater efficiency of preventive and correctional work with students with deviant behavior. The authors note that the problem of correcting the deviant behavior in adolescents is a complex one, in solving which social educators, psychologists, class teachers, specialists in physical culture and sports, municipal education authorities and internal affairs institutions should cooperate. The conditions for the effectiveness of further implementation of the “university-school” network interaction in correcting the behavior of deviant students by means of physical culture and sports activities are determined. The results of the study are of professional interest for physical education teachers, social educators, and psychologists.
Marco para la reflexión docente: una propuesta metodológica
Authors: Asenjo Zapata Natalia 
Published: August 2021

El propósito de este artículo es comprender cómo diferentes estrategias reflexivas incidieron en un proceso de cambio de creencias y prácticas de enseñanza de cuatro profesores de inglés en Chile. Esto, con el fin de establecer una propuesta metodológica de una batería de seis estrategias reflexivas para contribuir a la política pública, ya que aún no se contemplan indicaciones que permitan guiar y acompañar la reflexión docente. La metodología empleada contempla un análisis cualitativo a partir de lo propuesto por el análisis de contenido. Los resultados muestran que las estrategias funcionaron de forma distinta en cada uno de los participantes, estableciéndose cuatro procesos de cambio diferentes. De esta forma, se puede concluir que es necesario el diseño de una intervención que cuestione a los docentes mediante la utilización de diferentes tipos de preguntas y estrategias reflexivas, dependiendo del tipo de reflexión que se quiera promover.

Abstract
Joint analyses of small-scale cosmological structure probes are relatively unexplored and promise to advance measurements of microphysical dark matter properties using heterogeneous data. Here, we present a multidimensional analysis of dark matter substructure using strong gravitational lenses and the Milky Way (MW) satellite galaxy population, accounting for degeneracies in model predictions and using covariances in the constraining power of these individual probes for the first time. We simultaneously infer the projected subhalo number density and the half-mode mass describing the suppression of the subhalo mass function in thermal relic warm dark matter (WDM), M
hm, using the semianalytic model Galacticus to connect the subhalo population inferred from MW satellite observations to the strong lensing host halo mass and redshift regime. Combining MW satellite and strong lensing posteriors in this parameter space yields M
hm < 107.0
M
⊙ (WDM particle mass m
WDM > 9.7 keV) at 95% confidence and disfavors M
hm = 107.4
M
⊙ (m
WDM = 7.4 keV) with a 20:1 marginal likelihood ratio, improving limits on m
WDM set by the two methods independently by ∼30%. These results are marginalized over the line-of-sight contribution to the strong lensing signal, the mass of the MW host halo, and the efficiency of subhalo disruption due to baryons and are robust to differences in the disruption efficiency between the MW and strong lensing regimes at the ∼10% level. This work paves the way for unified analyses of next-generation small-scale structure measurements covering a wide range of scales and redshifts.

The technical limitations of capillary sequencing in providing insights on phylogeny have been greatly aided in recent years by the implementation of next generation sequencing platforms which can generate whole mitochondrial genome (mitogenome) sequences. In this study, enriched mitochondrial DNA of Cynopterus brachyotis from Mindanao, Philippines was sequenced using the Illumina MiSeq platform. A total of 653,967 clean paired-end reads was assembled using a MIRA-MITObim pipeline, resulting to a consensus mitogenome sequence length of 17,382 bases and a GC content of 41.48%, which is consistent with other published mitogenomes in fruit bats. The assembled C. brachyotis mitogenome was annotated using the MITOS online server and was able to resolve all mitochondrial genes, except for one transfer RNA gene (trnT) which may be further resolved by additional capillary sequencing of the region. Sequence analysis showed that the Philippine C. brachyotis is only 90%-91% homologous with other Cynopterus spp. based on its full mitogenome sequence. Phylogenetic analysis of fruit bat mitogenomes deposited in online repositories revealed that the Philippine C. brachyotis in this study has diverged from Asian Cynopterus, namely Cynopterus brachyotis and Cynopterus sphinx from other parts of Asia (100% bootstrap support) with the latter two forming a separate clade. This divergence at the species level was consistent with phylogentic inference using cytochrome oxidase 1 (CO1) and cytochrome B (cytb) gene markers. Our results strengthen the previously reported hypothesis that the C. brachyotis in the Philippines is distinct from its Asian counterparts and should be therefore elevated to a new species.
Organiser, réglementer ou démocratiser le travail ?
Authors: Plouviez Mélanie 
Published: August 2021

L’article interroge la normativité du travail en revenant à l’une des sources théoriques, bien que minorée, du droit français du travail et de la protection sociale : Émile Durkheim. L’article commence par présenter, en la déconstruisant, la lecture que Georges Friedmann a proposée de La Division du travail social dans Le Travail en miettes , lecture selon laquelle la réglementation durkheimienne du travail peut être rapprochée de l’organisation scientifique du travail défendue par Frederick Winslow Taylor. À rebours d’une telle interprétation, l’article déploie la pensée durkheimienne des normes du travail comme appel en faveur de la nécessaire réglementation juridique du travail sous la forme d’un « droit professionnel » et de sa tout aussi nécessaire démocratisation sociale et économique, dont la réforme du groupement professionnel doit constituer l’assise institutionnelle.
Le tournant entrepreneurial du droit du travail en France (1982-2017)
Authors: Willemez Laurent 
Published: August 2021

Les réformes du droit du travail en France dans les années 2016-2017 (loi El Khomri et ordonnances Macron) peuvent être vues comme l’acmé des politiques du travail menées depuis le milieu des années 1980. L’article revient sur cette véritable « révolution symbolique » que constitue le renversement du droit du travail d’un droit protecteur des salariés à un droit tourné vers l’entreprise. C’est le sens même du droit et sa signification qui ont donc changé, à la fois dans le monde du « social », entendu comme les acteurs politiques et administratifs des politiques du travail, et dans le champ académique, du côté des facultés de droit. Pour ce faire, l’article dresse d’abord un panorama des réformes mises en œuvre dans les trois dernières décennies et du discours qui les accompagne. Il analyse ensuite ses transformations analogues dans les facultés de droit et l’enseignement et de la recherche en droit du travail. Il revient enfin sur différents « lieux communs » où se croisent les différents acteurs de deux espaces sociaux, réunis autour de ce « tournant entrepreneurial » du droit du travail.
Le salaire et la propriété de l’outil, droits économiques de la personne
Authors: Friot Bernard 
Published: August 2021

Se libérer du postulat qu'il n'y a qu'une seule classe pour soi, la bourgeoisie capitaliste, permet de mettre en évidence le déjà-là communiste de conquis comme le salaire à la qualification personnelle et le financement de l'investissement par le cycle subvention/cotisation. Ce déjà-là qui peut fournir le tremplin de mobilisations offensives contre la « réforme », qui est, en réponse à ce déjà-là, une contre-révolution capitaliste du travail.
Un monopole d’État sur la création monétaire permettrait-il de réduire la dette publique ? Une étude de « l’argument du seigneuriage » à la lumière des débats sur la proposition « 100% monnaie »
Authors: Demeulemeester Samuel 
Published: August 2021

Cet article traite de « l’argument du seigneuriage » en faveur de l’émission publique de monnaie, en vertu duquel les finances de l’État pourraient être améliorées si celui-ci exerçait plus pleinement le privilège de création monétaire – privilège qui, pour une large part, est aujourd’hui exercé par les banques privées. Cet argument fut avancé dans les années 1930 par plusieurs partisans du plan de réforme « 100% monnaie » – tels qu’Henry Simons de l’Université de Chicago, Lauchlin Currie de Harvard, ou Irving Fisher de Yale –, qui réclamaient une couverture intégrale des dépôts en comptes courants par des réserves en monnaie légale. L’un de leurs arguments était, qu’en rendant à l’État l’intégralité du profit de seigneuriage, une telle réforme permettrait de réduire considérablement la dette publique. Dans les débats académiques, cependant, suite à une critique originellement formulée en 1935 par Albert G. Hart de l’Université de Chicago, cet argument fut largement rejeté comme purement illusoire. Hart affirmait que, parce que l’État, sous un « système 100% », serait probablement amené à subventionner les banques pour assurer la tenue des comptes courants, aucune réduction notable de la dette publique ne pourrait en résulter. Les partisans du « 100% monnaie » n’ont jamais répondu à cette critique, dont la conclusion a souvent été considérée comme définitive au sein de la littérature. Cependant, une étude approfondie de la question révèle que l’analyse de Hart apparaît contestable à au moins deux égards : l’un ayant trait aux sources du profit du seigneuriage, l’autre à sa répartition. Nous en concluons que l’argument du seigneuriage avancé par les auteurs du « 100% monnaie » n’était pas entièrement infondé.
Pandemia e desinformação: aspectos da linguagem e da multimodalidade em campanha do Tribunal Superior Eleitoral
Authors: Ribeiro Ana Elisa 
Published: August 2021

Este artigo analisa três vídeos que compõem a campanha publicitária “Se for fake news, não transmita”, cujo anunciante foi o Tribunal Superior Eleitoral, em 2020. As peças foram produzidas para uma comunicação com a população sobre os riscos das notícias falsas para a democracia, e a mensagem se valeu de uma analogia entre as transmissões das fake news e a dos vírus. O apresentador convidado foi o biólogo e youtuber brasileiro Atila Iamarino. A abordagem multimodal dos vídeos à luz da semiótica social visa a mostrar que a análise da composição dos modos semióticos é insuficiente para uma compreensão mais refinada, sendo necessário abordar as modulações dos recursos dentro dos modos selecionados e possíveis, em condições tecnológicas e midiáticas também consideradas. É apresentada uma composição esquemática da decupagem de textos em modos e suas modulações.

Fake news em tempos de pandemia: a urgência de novos multiletramentos na cultura digital
Authors: Pereira Andreatta Elaine 
Published: August 2021

Na era da cultura digital (Santaella, 2003), os novos multiletramentos necessários para produzir significados são mais exigentes, pois alteram a relação de consumo, recepção e produção de linguagens e discursos. Este artigo tem o objetivo de analisar fake news (Bucci, 2019; Frias Filho, 2018; Santaella, 2018) produzidas no período da pandemia causada pela COVID-19 no Brasil. Para tanto, avaliam-se as estratégias linguísticas e imagéticas de apelo e convencimento, assim como o tratamento digital das fakes news que refletem uma narrativa transmídia (Jenkins, 2009), o que pressupõe a necessidade de letramentos críticos capazes de interligar pessoas, objetos midiáticos e estratégias de construção de significado (Lemke, 2010). Desse modo, realizou-se a seleção de cinco (5) fake news que circularam em diversas redes sociais, com diferentes configurações, e impulsionaram a desinformação em relação ao número de mortes por COVID-19, recortando-se, para análise, as fake news a partir do tema “caixões vazios” que se utilizaram de imagens estáticas (Rojo e Moura, 2019; Santaella e Nöth, 1998), acompanhadas ou não de texto verbal e verificadas em agências de checagem. Compreende-se, ao final desta pesquisa que, se há liberdade para acessar muitas informações e relacionar-se pelas redes com várias pessoas, as práticas de leitura precisam buscar a compreensão das multissemioses presentes nos textos em circulação, assim como compreender as relações estabelecidas nos meios de transmissão e produção de textos em contextos digitais.
