Filament Leg–Leg Reconnection as a Source of Prominent Supra-arcade Downflows
Authors: Dudík Jaroslav , Aulanier Guillaume , Kašparová Jana , Karlický Marian , Zemanová Alena , Lörinčík Juraj , Druckmüller Miloslav
Published: September 2022

We report on the interaction of the legs of the erupting filament of 2012 August 31 and associated prominent supra-arcade downflows (P-SADs) as observed by the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory. We employ a number of image processing techniques to enhance weak interacting features. As the filament erupts, both legs stretch outwards. The positive-polarity leg also untwists and splits into two parts. The first part runs into the conjugate (negative-polarity) leg, tearing it apart. The second part then converges into the remnant of the conjugate leg, after which both weaken and finally disappear. All these episodes of interaction of oppositely oriented filament legs are followed by the appearance of P-SADs, seen in the on-disk projection to be shaped as loop tops, along with many weaker SADs. All SADs are preceded by hot supra-arcade downflowing loops. This observed evolution is consistent with the three-dimensional rr–rf (leg–leg) reconnection, where the erupting flux rope reconnects with itself. In our observations, as well as in some models, the reconnection in this geometry is found to be long lasting. It plays a substantial role in the evolution of the flux rope of the erupting filament and leads to prominent SADs.
Evolution of an Emerging Anti-Hale Region and its Associated Eruptive Solar Flares in NOAA AR 12882
Authors: Xu Zhe , Yan Xiaoli , Yang Liheng , Xue Zhike , Wang Jincheng , Qin Ying
Published: September 2022

Solar active regions that violate the Hale–Nicholson rule are rare, but once formed, they tend to be flare-productive. In this letter, we investigated the evolution of an anti-Hale region newly emerging from the active region AR 12882 with a regular Hale distribution. The entire active region became very active, producing two eruptive flares within 48 hr after the emergence of the anti-Hale region. Strong photospheric shear motions appeared in this anti-Hale region, changing its tilt angle from the north–south direction to the east–west direction. The flux emergence and shearing motions continuously injected magnetic energy and negative magnetic helicity into the upper atmosphere. Meanwhile, the upper coronal structure changed from double J-shaped to reverse S-shaped, forming a magnetic flux rope lying above the anti-Hale region. This magnetic flux rope erupted successfully, then re-formed and erupted successfully again, producing a C2.7 flare and an M1.6 flare, respectively. Moreover, a large cusp structure was observed to form next to the flaring region after the M1.6 flare. Accordingly, we conclude that the evolution of the emerging anti-Hale region provides sufficient magnetic energy and helicity for the flares, and the interaction between the emerging anti-Hale region and the preexisting Hale active region eventually promotes the flares to be eruptive.

Published: September 2022

BACKGROUND: Anterior translation of the tibia (ATT) is a secondary sign of an anterior cruciate ligament (ACL) tear. With advances in technology, new tools such as the Lachmeter are expected to replace computed tomography scanning (CT scan) in measuring the ATT.

AIM: This study aims to determine the diagnostic validity of the Lachmeter in measuring the ATT 6–12 months after ACL tear reconstruction.

MATERIALS AND METHODS: A retrospective diagnostic test with a Lachmeter was used to measure ATT in patients 6–12 months after ACL tear reconstruction, compared with the gold standard CT scan and using a consecutive sampling technique. The optimal cutoff value of ATT was determined with Lachmeter afterwards. Statistical Package for the Social Sciences version 21.0 was used for the data analysis.

RESULTS: There are 28 persons with a positive ATT (≥ 5 mm) and four people with a negative ATT (<5 mm) measured using CT scan out of 32 samples. The optimal cutoff of ATT with Lachmeter is ≥7.28 mm (Area under curve = 0.88, 95% CI, 0.67–1.00 and p = 0.004) with a sensitivity of 84.62%, specificity 83.33%, positive predictive value 95.65%, negative predictive value 55.56%, positive likelihood ratio (LR) 5.08, negative LR 0.18, and 84.38% accuracy.

CONCLUSION: Lachmeter is a new tool for determining ATT that is highly efficient and easy to use. With good sensitivity and specificity values, this new tool has been proven to be very good at measuring ATT compared to CT scan as the gold standard.
'The city is dying ... The suburbs are growing ... The country shrinks': spatial Maoism and Suburban Press
Authors: Frost Daniel
Published: September 2022

Historians have typically presented the early 1970s underground paper Suburban Press, a major stylistic influence on the emergence of punk, as a British application of Situationist ideas and aesthetics. However, in this narrative, the role of Mao Zedong and Maoism in the underground
press, and punk, gets reduced to their mimetic capacity to shock. This paper will reconsider Suburban Press within the context of Croydon's underground scene, to rescue an alternative narrative in which Mao and Maoism occupy a sincere and not only satirical position. It argues that
the 'suburban' in the title of Suburban Press had three distinct meanings: the middle-class left-wing politics of the young radicals' parents; working-class areas like New Addington, analogous to the French banlieue ; and the complex process of (sub)urbanisation typified by
Croydon's changing town centre. This paper thereby hints at a new history of the 'spatial turn' in which the influence of Maoism upon its key theorists – e. g., Henri Lefebvre, Michel Foucault, and Doreen Massey – is recognised. It concludes by suggesting some implications for
recent references to spatiality in leftwing politics in Britain, outlining a 'spatial Maoism' to add to the 'two lines of global Maoism' recently described by Colleen Lye.
'Serving the people'. A short history of Spanish Maoism (1964-1980)
Authors: García Eduardo Abad
Published: September 2022

1956 was an important date for Spanish communism. The Twentieth Congress of the CPSU was being held in Moscow, and the Communist Party of Spain (PCE) adopted the policy of 'National Reconciliation'. This became the starting point for Maoist dissidence and clashes with the party leadership,
whom they accused of 'revisionism'. In 1964 the first Maoist party was formed, the PCE (marxist-leninist), made up of radicalised youth as well as some communist veterans. The influence of Maoism then slowly increased and it started to infiltrate other social sectors: workers, students and
even Catholic groups. As a result of this influence, further organisations were created, such as the PCE (international), the Communist Movement, the Revolutionary Organisation of Workers, the Organisation of Spanish Marxist-Leninists and the Communist Organisation (Red Flag). During the final
years of the Franco dictatorship a number of Maoist groups committed themselves to armed struggle. The first to take this type of action were the militants of the Revolutionary and Patriotic Antifascist Front (FRAP), a short-lived group created by the PCE (m-l), which lasted from 1973 to 1976.
In response to the execution of several FRAP militants on 27 September 1975, the First October Revolutionary Antifascist Groups (GRAPO) were created. This organisation sought to overcome demoralisation in post-transition Spain through intensifying actions based on armed struggle, but it eventually
became a marginal force, as a result of persecution by the police. This article reviews the history of the Maoist political subculture in Spain over two decades from a social and cultural perspective, and analyses multiple aspects of this communist current, including its transnational networks,
collective memory and identity.
Ach Glück de Monika Maron. Genre et vieillissement à travers l’étude de l’espace
Authors: Chamayou-Kuhn Cécile
Published: September 2022

Dans le roman Ach Glück l’écrivaine Monika Maron pose la question de la place à laquelle peut prétendre Johanna, le personnage féminin, face à un monde figé et monotone qu’elle éprouve à un âge avancé. L’analyse de cette œuvre à travers le prisme de la spatialité permet de mettre en évidence le potentiel d’action que recèle le motif de la vieillesse chez Monika Maron. Celui-ci se révèle à travers les catégories d’analyse que sont le genre et l’âge. L’analyse démontre en effet que la romancière dénonce les structures patriarcales qui encadrent l’existence des individus à l’aube de leurs vieux jours à Berlin après la Réunification. Par ailleurs, Maron confère au thème du voyage la fonction d’un espace intermédiaire qui est lui-même traversé par une dynamique contribuant à faire vaciller les fondements de la vie de d’épouse et de mère que menait jusqu’alors Johanna. Or, cette mobilité se révèle être productive à un autre niveau. De fait, elle correspond également à un principe poétologique porté par des femmes artistes qui sont autant de figures tutélaires figurant la vieillesse et incarnant la quête d’un lieu où peut se déployer et s’affirmer la création féminine.
En oubliant, en écrivant. Vieillesse et amnésie créative dans les nouvelles d’Ulrike Draesner et d’Anna Katharina Hahn
Authors: Arlaud Sylvie
Published: September 2022

Ulrike Draesner ( Ichs Heimweg macht alles allein et Josef rennt ) et Anna Katharina Hahn ( Kommune Kalk ) ont renouvelé le regard porté sur la « vieillesse » en travaillant la langue à hauteur de corps dans trois textes courts parus entre 2003 et 2011. Les trois textes à la première personne mettent au centre de leur dispositif des « vieux » et des « vieilles » en s’appuyant sur leur dégénérescence physique et mentale pour opérer un effacement productif qui est aussi un bain de jouvence littéraire. Le travail sur l’identité, inscrite dans la langue et sa grammaire, sa constitution par la société et sa déconstruction par la maladie, accompagne une écriture qui brosse à rebours les clichés, l’horizon d’attente du lecteur et la langue. Comment façonner le monde alors même qu’il s’efface ? Quelle est la place du lecteur dans cet effacement ? Chacun des récits, entre « tournant linguistique » et « tournant social », est un exemple abouti de la force d’un art qui permet de proposer un changement de perspective sur la vieillesse et la maladie en engageant pleinement le lecteur.
La construction des légitimités d’une expertise scientifique au prisme de sa médiatisation : le cas de la « crise requin » à La Réunion
Authors: Losen Barbara
Published: September 2022

Cet article interroge l’évolution des légitimités de l’expertise scientifique qui a eu lieu de 2011 à 2015 dans le cadre de la gestion du risque requin à La Réunion, au prisme de sa construction médiatique. L’analyse d’articles issus de la presse locale en ligne couplée à celle des discours de journalistes locaux et d’experts scientifiques recueillis en entretiens, révèle la façon dont les contraintes des champs scientifique et journalistique, en termes d’enjeux et de pratiques communicationnelles, participent à la dynamique des représentations du rapport entre légitimité médiatique et sociale des experts scientifiques.
La science est-elle soluble dans des projets techno-industriels ? Querelles autour de la géothermie profonde à l’Eurométropole de Strasbourg (2012-2020)
Authors: Chavot Philippe , Masseran Anne , Serrano Yeny , Zoungrana Jean
Published: September 2022

Cet article analyse les désaccords entre mondes industriel et scientifique dans le champ de la géothermie profonde alsacienne des années 2010. Cette querelle où se croisent interprétations scientifiques et intérêts industriels reflète les divergences de vues entre les mondes sociaux en présence sur la façon dont la science et les scientifiques doivent intervenir dans les projets de géothermie. La notion de paradigme de communication combinée à celle d’ethos discursif permet de saisir les dynamiques qui fondent les discours publics sur la géothermie : du côté des industriels une communication d’acceptabilité insiste sur la maturité du domaine et la maitrise des risques ; du côté des scientifiques, des approches plus pédagogiques pointent les lieux où des travaux sont nécessaires pour optimiser le développement de la géothermie profonde. Les désaccords apparaissent au grand jour suite aux séismes affectant l’Eurométropole de Strasbourg en 2019 et 2020.

La phase d’information dans l’obligation de rendre des comptes. Le rôle des conseils d’administration dans les agences de l’Union européenne
Authors: Font Nuria , Pérez-Durán Ixchel
Published: September 2022

La création des agences de l’Union européenne a suscité des discussions normatives et théoriques sur leur imputabilité et leur légitimité démocratique. Cette étude examine dans quelle mesure différentes caractéristiques concernant le modèle institutionnel des agences les incitent à fournir des informations sur leurs performances. Pour ce faire, elle mesure quatre aspects pour lesquels leurs organes directeurs sont censés fournir des informations : les décisions de gouvernance, la performance des politiques, les questions financières et les interactions avec les parties prenantes. En utilisant un nouvel ensemble de données de déclarations informatives incluses dans 199 rapports d’activité annuels de 29 agences au cours de la période 2010-2016, cette étude démontre que l’imputabilité formelle influence positivement la fourniture d’informations sur les questions de gouvernance et de politiques, et que la création d’organes scientifiques au sein des agences améliore la fourniture d’informations sur les aspects liés à la gouvernance, la performance des politiques et leurs interactions avec les parties prenantes. Enfin, cet article constate que les agences qui pratiquent une réglementation plus directe sont soumises à de plus grandes exigences de transparence concernant leurs décisions de gouvernance et leurs interactions avec les parties prenantes. Remarques à l’intention des praticiens L’étude fournit aux praticiens un outil analytique pour évaluer la fourniture d’informations sur les décisions et les actions des conseils d’administration sur les questions de gouvernance, la performance des politiques, les aspects financiers et leurs interactions avec les parties prenantes.
Vieillir, trébucher, créer
Authors: Brody Baudin Marianne
Published: September 2022

Les couches de temps s’ajoutent les unes aux autres, se superposent mais aussi se plissent, se fondent entre elles et créent l’épaisseur subjective. Une part de cette épaisseur nous reste inconnue, enfouie, refoulée, inconsciente, comme étrangère. La prise de conscience de la vieillesse, son identification selon les modes passif et actif, comprenant non seulement la finitude mais aussi toute cette épaisseur jamais pétrifiée de l’histoire d’un sujet, renforce l’intérêt pour la vie même et milite pour son accomplissement le plus abouti. Pour qu’elle ait lieu, l’inattendu est précieux : le modèle du trébuchement est proposé dans l’article comme forme de l’inattendu qu’il ait lieu au détour d’un chemin, au cours d’une analyse ou au hasard d’une rencontre, quand la sortie de l’habitude, voire la désorientation momentanée sont autant d’opportunités pour engager un ou des changements de point de vue. Loin de la redouter ou de la repousser et surtout de la dénier, reconnaitre la vieillesse, la sienne comme celle des autres, inscrit le sujet dans sa trajectoire personnelle, proche des autres, bien qu’unique. L’auteur illustre son propos par deux vignettes cliniques et une analyse du Bal de têtes, dernière partie de la Recherche du Temps Perdu où Proust, rencontrant la vieillesse, comprend sa vocation d’écrivain et l’importance de la création d’une œuvre.
Optimal assignment of infrastructure construction workers
Authors: Wang Haoqing , Yi Wen , Liu Yannick
Published: September 2022

Worker assignment is a classic topic in infrastructure construction. In this study, we developed an integer optimization model to help decision-makers make optimal worker assignment plans while maximizing the daily productivity of all workers. Our proposed model considers the professional skills and physical fitness of workers. Using a real-world dataset, we adopted a machine learning method to estimate the maximum working tolerance time for different workers to carry out different jobs. The real-world dataset also demonstrates the effectiveness of our optimization model. Our work can help project managers achieve efficient management and save labor costs.

Differential order analysis and sensitivity analysis of a CoVID-19 infection system with memory effect
Authors: Sajid Mohammad , Dhar Biplab , Almohaimeed Ahmed S.
Published: September 2022

The paper deals with numerical analysis of solutions for state variables of a CoVID-19 model in integer and fractional order. The solution analysis for the fractional order model is done by the new generalized Caputo-type fractional derivative and Predictor-Corrector methodology, and that for the integer order model is carried out by Multi-step Differential Transformation Method. We have performed sensitivity analysis of the basic reproduction number with the help of a normalized forward sensitivity index. The Arzelá-Ascoli theorem and Fixed point theorems with other important properties are used to establish a mathematical analysis of the existence and uniqueness criteria for the solution of the fractional order. The obtained outcomes are depicted with the help of diagrams, narrating the nature of the state variables. According to the results, the Predictor-Corrector methodology is favorably unequivocal for the fractional model and very simple in administration for the system of equations that are non-linear. The research done in this manuscript can assure the execution and relevance of the new generalized Caputo-type fractional operator for mathematical physics.
La guerra de drones: caza, fantasía y el arte de asesinar
Authors: Zulaika Joseba
Published: September 2022

El artículo examina la guerra de drones como una forma de caza llevada a cabo por vía satélite desde la base militar aérea de Creech cerca de Las Vegas. El evento revelador inicial es el trauma que sufren los pilotos de drones debido a la intimidad visual con la que contemplan las consecuencias fatídicas de sus acciones. Se analiza el papel de la fantasía en el comportamiento de caza de los pilotos y en la retroalimentación mutua entre terrorismo y contraterrorismo. Se describe cómo funciona «el arte de matar” (De Quincey) en la guerra de drones a base de narrativa, eufemismos y video juegos. El artículo tiene en cuenta el papel trágico de Obama en la proliferación y normalización de los drones armados, así como la situación actual bajo la presidencia de Biden.
Trascendiendo la socialidad humana: relaciones eco-cosmológicas entre entidades en la ecosfera
Authors: Abad Espinoza Luis Gregorio
Published: September 2022

Basado en una discusión de las contribuciones teóricas de Claude Lévi-Strauss y Pierre Clastres, este artículo explora las relaciones sociales como algo más que una dimensión humana. Aunque fuertemente analizadas por ambos antropólogos, estas relaciones parecen involucrar todo el sistema ecológico y cosmológico de las sociedades indígenas. En este sentido, la reciprocidad, la cohesión social y el intercambio pueden entenderse como interrelaciones materiales e inmateriales entre entidades de un mundo más que corpóreo. Sostengo, entonces, que, para ir más allá de la mera conceptualización antropocéntrica de la socialidad en una naturaleza buena para pensar, necesitamos concebir holísticamente los niveles interconectados de relaciones e intercambios tróficos, socio-estructurales y socio-cósmicos entre seres humanos y no humanos en el ecosistema.
Cuerpos que hablan: apuntes sobre la transmisión testimonial de las víctimas del franquismo en la Querella Argentina
Authors: Montoto Ugarte Marina
Published: September 2022

En la mayor parte de la literatura social sobre el testimonio, este se trata en su dimensión narrativa o discursiva. En otras palabras, como lo dicho o lo enunciado. Tomando esto como punto de partida, el objetivo de este artículo será problematizar esta noción, reflexionando sobre el testimonio en aquellos contextos en los que, por diferentes razones, no se puede hablar, por lo que la transmisión de las experiencias de violencia se ha podido dar de otra manera. Se tomará como punto de partida una investigación realizada con diferentes familiares y víctimas del franquismo querellantes en la denominada Querella Argentina contra los crímenes del franquismo. En las conversaciones y entrevistas con los querellantes, las alusiones al silencio compartido entre las familias, el miedo vivido durante años y al mal cuerpo presente en sus biografías se convirtieron desde el principio en un material discursivo denso y heterogéneo, difícil de ubicar y analizar. El artículo aborda el análisis de este material discursivo planteando un hoja de ruta donde se acaba transformando la conceptualización del testimonio.
The impact of inundation and sandstorms on the growth and survival of the mangrove Avicennia marina seedlings in the southern Red Sea

Published: September 2022

Mangroves occur in tropical and subtropical regions, including harsh arid areas. Little is known about how the environmental conditions of deserts influence the ecology of mangrove seedlings. The seedlings of the mangrove Avicennia marina were examined in situ in a natural stand of the southern Red Sea coast of Saudi Arabia to (1) estimate and compare the growth rate of A. marina between selected microhabitats with different tidal exposures, and (2) examine the influence of sandstorms on the growth and survival of the seedlings. Samplings were conducted in four zones established according to their tidal exposure: low tidal exposure (Z1), medium tidal exposure (Z2), high tidal exposure with numerous burrows (Z3), and high tidal exposure with a few or no burrows (Z4). Vertical growth and mortality of the seedlings and selected environmental variables were quantified. The results show that seedling growth rates differed significantly between the sampling zones, the highest growth being found in the high tidal regions (Z3 followed by Z4) and the lowest growth in Z1. Growth rate followed a significant decreasing pattern over time, coinciding with increasing air temperature and decreasing relative humidity. Sandstorms showed a marked increase in July, leading to massive dust deposition that caused extensive mortality of the seedlings by burial. Our study highlights that seedling growth can be affected by the extent of tidal inundation and that sandstorms act as a natural stressor.
Towards a Students’ Dropout Prediction Model in Higher Education Institutions Using Machine Learning Algorithms
Authors: Oqaidi Khalid , Aouhassi Sarah , Mansouri Khalifa
Published: September 2022

Using machine learning to predict students’ dropout in higher education institutions and programs has proven to be effective in many use cases. In an approach based on machine learning algorithms to detect students at risk of dropout, there are three main factors: the choice of features likely to influence a partial or total stop of the student, the choice of the algorithm to implement a prediction model, and the choice of the evaluation metrics to monitor and assess the credibility of the results. This paper aims to provide a diagnosis of machine learning techniques used to detect students’ dropout in higher education programs, a critical analysis of the limitations of the models proposed in the literature, as well as the major contribution of this arti-cle is to present recommendations that may resolve the lack of global model that can be generalized in all the higher education institutions at least in the same country or in the same university.

Des bras de Vénus aux fauteuils de l’Académie, ou comment le passage de Vénus permit à Ernest Mouchez de devenir le premier marin directeur de l’Observatoire de Paris
Authors: Boistel Guy
Published: September 2022

Officier issu de l’Ecole navale, très tôt versé dans les observations astronomiques, héros de la guerre de 1870-1871, Ernest Mouchez s’impose peu à peu comme le personnage du consensus, permettant de rompre avec une tradition française qui plaçait ses polytechniciens à la tête des grandes institutions astronomiques françaises. Le succès remporté lors de l’expédition pour le passage de Vénus à l’île Saint-Paul, dans l’océan indien, puis la création de l’observatoire de la Marine, dans le parc Montsouris à Paris, qui servira à former des officiers, des voyageurs et géographes, sont les deux faits majeurs qui permettent à Mouchez de devenir le premier marin directeur de l’Observatoire de Paris en juin 1878.

Des jeux de la Nature aux médailles de la Création
Authors: Gaudant Jean
Published: September 2022

Après avoir été longtemps considérés comme des « jeux de la nature » ou comme produits par l’action d’une « force plastique », les fossiles furent enfin reconnus vers la fin du xviie siècle, principalement grâce à Sténon, comme des restes d’êtres vivants. Ils acquirent bientôt avec Hooke le statut de « médailles de la nature », avant d’être considérés comme des témoins du déluge. Ils accédèrent alors au statut d’« archives » et contribuèrent ultérieurement à l’établissement d’une stratigraphie dont Soulavie et de Luc font figure de précurseurs.

Dans la forêt, le genre
Authors: Hillenkamp Isabelle
Published: September 2022

La politique climatique internationale a fait des forêts tropicales la cible de paiements pour services de captation de carbone. Au Vale do Ribeira (Brésil), ces dispositifs s’inscrivent dans des conflits socio-environnementaux préexistant et opposant les habitant·es de communautés locales à une vision étroite de conservation de la nature dans les politiques environnementales, autant qu’à de grands projets d’investissement. L’article propose une analyse genrée et située au double plan matériel et politique des pratiques « de résistance » que ces habitant·es ont développé à travers l’agroécologie. Il montre que le rapport construit avec la nature dans l’agroécologie, de type holiste, fonctionnel et en même temps spirituel, s’élargit dans le cas des femmes pour intégrer leur responsabilité socialement attribuée pour le care, ce qui les situe au premier plan de l’opposition à la conception fragmentée et utilitaire d’une nature vide d’humains de la politique environnementale et climatique.
Crise climatique, crise politique
Authors: Boutié Élise
Published: September 2022

En détruisant entièrement la ville de Paradise (27 000 habitant·e.s) et ses environs, l’incendie le plus meurtrier de l’histoire des États-Unis a provoqué un choc important. Cet article s’intéresse à la façon dont cette catastrophe a affecté l’attachement à la forêt. En partant du choc de découvrir le paysage incendié, il s’agit de comprendre de quoi est fait cet attachement. Nous analysons aussi bien les récits qui racontent cet attachement après l’incendie que le rapport aux institutions en charge de la gestion des forêts. L’incendie a bouleversé le rapport au paysage et fait de l’expérience de vivre dans une forêt sans arbre une situation déroutante.
Alpine Sentinels
Authors: Dall’Ò Elisabetta
Published: September 2022

This research was carried out within the highland communities of the Mont-Blanc area (Italian side). This Alpine region is characterized by a huge variety of biodiversity and environments in which human and non-human species coexist, coping with extreme natural phenomena due to specific weather conditions, topography, and consequences of the current climate crisis (e.g. glaciers melting, heatwaves, extreme events). In this context, despite scientific evidence of the impacts of global warming on the land, the socio-cultural attitude of the people exposed (e.g. perception and response) tends to hide or scotomize risk. In the field of “natural” risks and “climate change”, we usually identify “perception” on a theoretical and methodological level as a mainly human category (belonging to homo sapiens faber ludens). Nevertheless, throughout my inquiry into the socio-cultural impacts of global warming on the Alps, I encountered some “non-human” figures such as wild and farm animals, and even insects and plants, which have always played a crucial cultural role for Alpine communities from their imaginaries to their founding myths and economies. These species are of great importance not only in “perceiving and bringing” the first signs and symptoms of the “climate crisis”, but also in “anticipating” it as sentinels (Keck et al., 2020). Impacts inscribed in the animals’ bodies (e.g. chamois) and behaviour, and even in their “natural habitats”, were first observed, perceived and blamed on the climate crisis by local hunters. The aim of this proposal is to analyze, through the case of Mont-Blanc, how human-animal interactions at the micro scale may become key tools to anticipate, read, comprehend and explain the local and global crisis that is underway.
Onirisme viral

Cet article tente de montrer comment des non-sujets comme les coronavirus, les méduses, Big Brother, la mort, l’argent, l’État, institués en sujets par des imaginaires sociaux, rêvent, et comment leurs rêves extorqués aux humains et capitalisés par ces « êtres » sans conscience ni volonté, sont le paradigme de vies déshumanisées par de cyniques oppressions et de folles actions des images vivantes de leurs rêves. Le cauchemar de la Covid-19, dont l’humanité se réveillera, sera une composante de l’histoire du corps invisible des rêves, qui est le corps invisible des sociétés. La perspective de l’onirisme viral va au-delà des conceptions freudiennes et de la sociologie dispositionnaliste du rêve, car sa problématique est celle des non-sujets qui vivent et rêvent hors d’eux.

Entretien avec HIMBY (Hot In My Backyard), un collectif d’anthropologues italiens qui propose des ateliers de formation et des parcours de recherche-action pour faire sortir le débat sur le changement climatique de la sphère académique, et pour comprendre le changement climatique non seulement comme une question géophysique ou d’expertise, mais aussi comme une question sociale et culturelle.
Temporal and timeless cognition in physics
Authors: Šorli Amrit , Čelan Štefan
Published: September 2022

In experimental and theoretical physics, we measure time as the duration of material changes that run into space. We have no scientific evidence that would be based on the elementary perception and would prove that clocks run in some physical time. Universal space is time-invariant,
in the sense that time is not its fourth dimension. In time-invariant space, motion happens only in space and not in time. Time as duration enters existence as an emergent physical quantity and is the result of the observer's measurement. Linear time “past-present-future” is psychological
time that runs only in the brain. Universal change runs in time-invariant space, in this sense the universe is timeless. Temporal cognition occurs in the frame of psychological time, and timeless cognition occurs without the impact of psychological time.
Deep Learning Model for Dynamic Hand Gesture Recognition for Natural Human-Machine Interface on End Devices
Authors: Chang Tsui-Ping , Chen Hung-Ming , Chen Shih-Ying , Lin Wei-Cheng
Published: September 2022

As end devices have become ubiquitous in daily life, the use of natural human-machine interfaces has become an important topic. Many researchers have proposed the frameworks to improve the performance of dynamic hand gesture recognition. Some CNN models are widely used to increase the accuracy of dynamic hand gesture recognition. However, most CNN models are not suitable for end devices. This is because image frames are captured continuously and result in lower hand gesture recognition accuracy. In addition, the trained models need to be efficiently deployed on end devices. To solve the problems, the study proposes a dynamic hand gesture recognition framework on end devices. The authors provide a method (i.e., ModelOps) to deploy the trained model on end devices, by building an edge computing architecture using Kubernetes. The research provides developers with a real-time gesture recognition component. The experimental results show that the framework is suitable on end devices.

Published: September 2022

The purpose of this paper is to investigate the relationships between digitalization, supply chain integration, and firm performance. Data are analyzed by the partial least square structural equation modeling (PLS-SEM). The results revealed that both digitalization in the supply chain and supply chain external integration positively affected company performance. Further, supply chain external integration partially mediated the relationship between supply chain digitalization and firm performance. In addition, it was found that financial performance is enhanced through different paths for large enterprises and SMEs. Large enterprises improve financial performance through supply chain integration after efforts spent on the digitalization of their supply chain, while SMEs improve financial performance directly through supply chain digitalization. These findings provide insights for managers and policymakers of large enterprises and SMEs in formulating appropriate implementation strategies for digital transformation.
A SUPERAÇÃO DA PEDAGOGIA DA MANUTENÇÃO
Authors: Degrandis Fernando
Published: September 2022

A sociedade complexa em que vivemos influencia diretamente as experiências de aprendizagem nas escolas. A escola, por sua vez, deveria ter que papel em relação a esta realidade? Passivo? Reativo? Propositivo? A escola, composta por sujeitos dotados de direitos, relaciona-se de que maneira com as demandas sociais? Estas são problematizações importantes deste texto, que tem como objetivo analisar esta relação, em especial a função da escola frente a formação dos sujeitos. Para tal, foi utilizado uma metodologia qualitativa, de caráter explicativo, a qual conta com a aplicação de questionários a três públicos (estudantes, professores e gestores) de duas escolas particulares do Rio Grande do Sul, bem como referencial bibliográfico e documental da Rede Marista de Educação.  A análise dos questionários, com auxílio de categorização, indica que os estudantes aprendem com os diferentes sujeitos no espaço escolar. Ganha destaque uma função específica, a do professor dinâmico. Também, as técnicas que problematizam, contextualizam e promovem experiências são identificadas pelos estudantes como aquelas que mais ajudam em suas aprendizagens. Um currículo que assume a complexidade da sociedade e dos sujeitos supera a pedagogia da manutenção e coloca em ação a pedagogia da invenção e produção dos saberes, considerando sujeitos como protagonistas.

O objetivo deste trabalho foi analisar a contribuição do Programa Bolsa Família (PBF)  para a permanência dos alunos de escolas públicas, no município de São Sebastião do Tocantins, no período de 2015 a 2019. A pesquisa adotou a abordagem qualiquantitativa, com delineamento exploratório-descritivo e foi desenvolvida por meio de pesquisas bibliográfica e documental. De acordo com os resultados, nesse período, foram gastos um valor de R$ 12.447.604,48, atendendo um total de 3.385 estudantes. Os dados revelaram que os estudantes da rede pública, atendidos pelo PBF, no município de São Sebastião do Tocantins, tiveram uma taxa de aprovação de 86,55%. Conclui-se pela significativa contribuição do PBF na permanência, frequência e participação dos estudantes atendidos no processo de escolarização. Constatou-se, ainda,  que o auxílio do PBF se estende às demais pessoas da família que, em muitos casos, dependem desta renda para sua subsistência.

Dentre diversos temas presentes no currículo da educação brasileira, a Educação Ambiental (EA) é focalizada neste artigo devido ser tema de profunda relevância para sociedade contemporânea e obrigatória em todos os níveis educacionais. O objetivo é apresentar resultados de pesquisa a respeito da presença e das concepções de EA que fundamentam currículos de formação inicial de professores. Apoiados em referencial teórico de orientação crítica, foram desenvolvidas pesquisa bibliográfica e documental. Foram selecionados dois projetos pedagógicos de cursos de licenciatura em Ciências Biológicas de instituições públicas do Estado de Goiás. Orientados pelo materialismo histórico-dialético, foi possível perceber, em ambos os documentos, a preocupação em atender as exigências das legislações nacionais, além da ampla citação de adoção de abordagem transversal e interdisciplinar para tratar EA por meio de projetos. Porém, observou-se também falta de clareza a respeito da compreensão de como implementar tais abordagens, bem como inclinação para concepção instrumental.

Published: September 2022

O ensino remoto foi a forma encontrada para a continuidade das aulas no período de isolamento social, por conta do agravamento da pandemia por covid-19. Dessa forma, os professores tiveram que se reinventar e recriar práticas pedagógicas de ensino, adaptando, para aulas síncronas, metodologias que, antes, eram utilizadas presencialmente. Este artigo investiga a utilização de metodologias ativas no ensino remoto emergencial, no curso de Pedagogia da Faculdade Ieducare. O estudo caracteriza-se como pesquisa quantitativa e qualitativa, valendo-se da aplicação de questionário eletrônico com os discentes do curso de Pedagogia da referida instituição. Como resultados, destacamos que a utilização de metodologias ativas no ensino síncrono interfere positivamente no processo de aprendizagem, visto que a amplificação do uso de diferentes metodologias de ensino pode proporcionar aos pedagogos em formação o aproveitamento e o desenvolvimento de novas habilidades e competências, tendo a diversidade de recursos didáticos como fundamental para sua prática docente. Porém, a ausência das adequações necessárias dos usos dessas metodologias no ensino remoto, em alguns relatos, afetou negativamente o processo de aprendizagem dos discentes.

The Cu2+ in the drinking water has a very serious impact on human health and social ecology. Many countries have the policy on the Cu2+ concentration limitation in drinking water and the industrial Cu2+ emission standards for the treated wastewater. Scientists have developed many methods to remove Cu2+ from wastewater. Among all the adsorption method is widely used due to its high efficacy, feasibility and low cost. The adsorbent is critical to achieving superior Cu2+ removal result. In this paper, Fe3O4/carbon-graphene oxide nanocomposites (Fe3O4@C-GO) were prepared by a hydrothermal method. The Fe3O4@C-GO is the main absorbent to Cu2+ through chemisorption. The specific surface area of Fe3O4@C-GO dramatically increases from 16 m2/g of Fe3O4@C to 62 m2/g, which expands the Cu2+ absorption capacity up to 350 mg/g. Fe3O4 nanoparticles with about 12 nm in diameter are uniformly encapsulated in the C-GO matrix, and therefore the Fe3O4@C-GO can be easily separated from the solution via magnetics. This adsorbent is also very easily recovered by an external magnetic field from the treated wastewater and has high reusability.

Published: September 2022

This paper deals with the issue of detection of internal defects and failures of concrete structures with emphasis on the use of non-destructive methods. All parts of the structure that reduce its service life or bearing capacity can be considered as internal defects and failures. These are, for example, gravel nests, cracks, delamination, caverns etc. Due to the prevalence of concrete structures, the development of this part of diagnostics is very important both for the safety of their users and to reduce the economic costs of their future repairs.

Published: September 2022

A well-controlled multistage hydrothermal technique was developed to synthesise hierarchical zinc oxide (ZnO) nanomaterials with a high surface-to-volume ratio. Hierarchical ZnO nanomaterials, hierarchical nanowires (HNWs) and hierarchical nanodiscs (HNDs), assembled from initial mono-morphological nanomaterials, ZnO nanowires, and ZnO nanodiscs respectively were prepared by sequential nucleation and growth following a hydrothermal course. The hierarchical nanomaterials composed of one-dimensional nanowire building blocks were obtained by introducing zinc nitrate as a source of zinc ions during the second growth phase. In comparison to their initial monomorphological counterparts, the prepared HNWs and HNDs showed superior photocatalytic performances. The improvement in the photocatalytic performance was ascribed to the reduction in dimensionality, the ultrahigh surface-to-volume ratio, the expanded proportion of the exposed polar area, and the creation of nanojunctions between the secondary nanowires and initial ZnO nanowires or nanodiscs. This work paves the way for the low-cost, large-scale, and low-temperature production of ZnO nanomaterials with superior photocatalytic properties.
