Nouveau régime forestier et conditions de travail en sylviculture : retour vers le futur?
Authors: Gesualdi-Fecteau Dalia , Venne Béatrice , Matte Guilmain Laurence , Asselin Hugo 
Published: March 2023

En 2013, le gouvernement du Québec a introduit un nouveau régime forestier qui a transformé la dynamique dans la gouvernance de la forêt publique. Parmi les changements apportés, l’État est désormais chargé de planifier et de gérer les activités d’aménagement forestier.
L’aménagement forestier comprend des activités commerciales et non commerciales. De 1986 à 2013, le gouvernement attribuait aux entreprises forestières des volumes de bois à long terme au moyen de « contrats d’approvisionnement et d’aménagement forestier » (CAAF). Ces entreprises avaient également la responsabilité d’assurer les travaux sylvicoles non commerciaux visant la régénération des peuplements forestiers. La Loi sur l’aménagement durable du territoire forestier, en vigueur depuis 2013, a transformé en profondeur l’organisation des activités dans ce secteur. Sur le plan des activités commerciales, l’octroi de CAAF est remplacé par des « garanties d’approvisionnement », lesquelles confèrent à leurs bénéficiaires un volume de bois de la forêt publique à des fins de transformation. Sur le plan des activités non commerciales, l’État assume désormais l’entière responsabilité de la planification et de la gestion des opérations, jadis confiée aux titulaires de CAAF.
À partir de données empiriques, ce texte met en lumière la façon dont le régime forestier instauré en 2013 a permis l’émergence d’acteurs, exogènes au champ du droit du travail, dont les pratiques et les schémas d’action façonnent aujourd’hui les conditions de travail des ouvriers et des ouvrières sylvicoles effectuant des tâches non mécanisées. Cette main-d’oeuvre effectue des opérations d’éducation de peuplement au moyen d’une scie débroussailleuse ainsi que du reboisement. Les acteurs identifiés interviennent dans la dynamique d’attribution et de supervision des contrats de travaux sylvicoles non commerciaux et jouent un rôle de contrôle et de surveillance des conditions de travail, laissant aux parties à la relation d’emploi un pouvoir limité.

Précis

En 2013, le gouvernement du Québec a introduit un nouveau régime forestier sur fond de crise sociale alors que plusieurs estimaient que l’exploitation de la forêt se faisait de façon erratique et sans égards aux écosystèmes et communautés s’y établissant. L’un des objectifs poursuivis par le nouveau régime forestier était notamment de mettre en place une gestion forestière assurant le développement du « potentiel économique, écologique et social des forêts ». Qu’en est-il toutefois des conditions de travail de la main-d’oeuvre assurant la régénération des peuplements forestiers? À partir de données empiriques, ce texte explore la façon dont la détermination des conditions de travail des ouvriers et des ouvrières sylvicoles dépend de l’intervention d’acteurs exogènes au champ du droit du travail.
Construção de uma falsa consciência da realidade

Este artigo tem como referência parte de um capítulo da dissertação de mestrado em Educação. O objetivo é demonstrar como o pensamento gramsciano pode auxiliar na compreensão dos processos e consequências da produção de Fake News no mundo contemporâneo, e compreender à seguinte exigência de Gramsci: necessitamos de uma escola ligada à vida (GRAMSCI, 1991). Para então, analisar um possível caminho para a educação do século XXI, no sentido da formação dos sujeitos para uma realidade permeada de falsos discursos, os quais buscam criar uma falsa consciência da realidade. O percurso metodológico da pesquisa é guiado pela Hermenêutica que nos ajuda a compreender as narrativas em seus dizeres e silêncios que produzem uma concepção de mundo, a partir de uma relação que ultrapassa o tempo aproximando uma discussão da atualidade com o pensamento de Antonio Gramsci. Assim, o aporte teórico se concentra em três grandes intelectuais que dialogam: Gramsci (1991 e 2000), Freire (1979; 1986 e 2019) e Martín-Barbero (2014). Ao concluir o artigo, acreditamos ter compreendido a urgência de refletir e discutir em profundidade o que permeia a produção de Fake News e os impactos diretos na formação dos sujeitos, o qual se depara constantemente com falsos discursos da realidade. Além da necessidade de introduzirmos práticas educomunicativas, tanto na educação formal quanto informal.
Profissionalidade docente nas políticas curriculares para a Educação Infantil no Brasil:

O artigo investiga, do ponto vista da Teoria Política do Discurso, de Ernesto Laclau e Chantal Mouffe, as articulações discursivas de diferentes agentes e organizações que, no Brasil, disputaram hegemonia em torno da profissionalidade docente para a Educação Infantil no contexto de produção das Diretrizes Curriculares Nacionais para a Educação Infantil – DCNEI (BRASIL, 2009) e da Base Nacional Comum Curricular para a Educação Infantil – BNCC/EI (BRASIL, 2018). Como estratégia de pesquisa, manejou-se com formações discursivas, fazendo emergir as contingencialidades que possibilitaram a constituição de certos discursos frente a um exterior antagônico. Argumenta-se que múltiplas formações discursivas acerca da infância, do ser e do agir docentes, deixaram rastros nesses documentos, ressaltando-se a precariedade dos sentidos que se estabilizaram, sendo, portanto, impossível a fixação de um sentido específico e último dessa docência e sua formação profissional, pela existência de outros enunciados que disputam a hegemonia, ameaçam e se antagonizam nos processos políticos. Aposta-se na descentralização dos sujeitos. Crianças e professoras de Educação Infantil existem através das relações que estabelecem entre si, sempre em contextos particulares. As identificações são construídas e reconstruídas em contextos específicos, mutáveis. Constituem-se em processos híbridos e justapostos, construídos de maneira dinâmica e fluida. Estudar as políticas curriculares a partir desse enfoque discursivo possibilitou deslocamentos de articulações de sentidos e a reconfiguração de modos instituídos de docência, desestabilizando estruturas tidas como estáveis.

Published: March 2023

O desempenho esportivo é influenciado por múltiplas habilidades. Com o objetivo de aprimorar habilidades psicológicas, diversas intervenções têm sido desenvolvidas, como o treinamento de mindfulness (TI), tornando-se necessário avaliar os efeitos dessas intervenções para futuros direcionamentos. O presente estudo teve como objetivo investigar os efeitos do TI no desempenho esportivo e nas habilidades psicológicas de atletas por meio de uma revisão sistemática. Esta revisão seguiu as recomendações do PRISMA. Foram incluídos estudos randomizados, não randomizados e intervenções pré e pós, que avaliaram o desempenho esportivo e habilidades ​​psicológicas por meio de instrumentos e procedimentos quantitativos, com amostras compostas por atletas profissionais e amadores, disponíveis em português, espanhol e inglês, e publicados entre 2010-2020. As buscas foram realizadas no MEDLINE, PsycNet, Scopus, LILACS, Web of Science e SPORTDiscus. A elegibilidade e a qualidade dos estudos foram avaliadas por dois pesquisadores independentes. As pesquisas identificaram 1579 artigos e, após análise, 32 estudos foram incluídos. Foi possível identificar efeitos positivos do TI em diferentes variáveis: 11 estudos encontraram efeitos positivos no desempenho esportivo, 14 no estado de mindfulness, 9 no estado de fluxo, 5 na redução da ansiedade competitiva, 3 no estresse, 4 na ansiedade geral e 2 no pessimismo. Conclui-se que o TI pode promover o desempenho esportivo e habilidades psicológicas em atletas, porém é necessário desenvolver estudos com melhor qualidade, especialmente no Brasil.
DIGITAL ACTIVISM IN TURKEY: ISTANBUL CONVENTION AS A SYMBOL OF WOMEN’S MOVEMENT
Authors: ÖZTUNÇ Müge 
Published: March 2023

ABSTRACT
Digital platforms that allow individuals to interact and offer a public space where people can share the content they produce and seek their rights play a crucial role in organizing activist protests, promoting new representations, and presenting adversary political voices. New activism, called 'digital activism,' is the activities by individuals or organizations in the digital environment to create the social change they desire. Social movements that started on these platforms with the claim of a better world while expressing social discomforts that are unsuitable for the flow of life may also offer new solutions.
This study reveals the social and political dimensions of how digital activism is shaped in Turkey through the Istanbul Convention, which appears to be the symbol where women, and non-governmental organizations, have struggled for years. The social struggle for both the existence and the implementation of the protection mechanisms of the Istanbul convention, was terminated by the Presidential decree, was analyzed with the content analysis method. Twitter posts under the hashtags "#İstanbulSözleşmesiYaşatır," (IstanbulConventionGivesLife), "#İstanbulSözleşmesindenVazgeçmiyoruz," (WeWon'tAbandonTheIstanbulConvention), "#İstanbulSözleşmesi" (IstanbulConvention) and explored categories related to the reflections of digital activism in Turkey was interpreted. According to the results, while the categories such as informing the public, not yielding, acting together for the benefit of society, and not giving up in the online struggle come to the fore, it is seen that digital is actively used in transferring activism offline. Another important finding of the research is that the main opposition party, individual activists, bar associations, and lawyers, especially women's non-governmental organizations, come to the fore as the most active groups and play an active role outside of digital platforms by directing the society.

As a productive ecosystem component, mangroves provide critical services to humankind. Mangroves may be a source of antibacterial compounds that could be used as a natural treatment for managing bacterial infections. This study determined the phytochemical constituents of leaf extracts of three selected mangrove species Avicennia marina (Bungalon), Rhizophora apiculata (Bakhaw), and Sonneratia alba (Pagatpat), using the Test-tube Method and antibacterial sensitivity using an Agar Well-Diffusion Method found in the coastal areas of Talisay City, Negros Occidental, Philippines. The results showed that the three species of mangroves leaf methanolic extracts exhibit susceptibility to antibacterial properties against S. aureus; it was observed that S. alba has the highest inhibitory effect on S. aureus among the three selected mangrove species. There was a significant difference between the positive control (Linezolid 30 mcg) and the methanolic crude extract of R. apiculata (MD = 27.97, p < 0.01), A. marina (MD = 24.37, p < 0.01), and S. alba (MD = 23.09, p < 0.01). On the contrary, A. marina and S. alba did not differ significantly with p= 0.172; this means that the antibacterial activity of methanolic crude extracts of A. marina and S. alba are comparable but significantly differ with the positive control (Linezolid 30 mcg). The qualitative phytochemical analyses of the three species of mangroves' leaf methanolic extracts showed flavonoids, phenols, saponins, and tannins. Terpenoids were present only on R. apiculata.

ImportanceWhile epinephrine has been widely used in prehospital resuscitation for pediatric patients with out-of-hospital cardiac arrest (OHCA), the benefit and optimal timing of epinephrine administration have not been fully investigated.ObjectivesTo evaluate the association between epinephrine administration and patient outcomes and to ascertain whether the timing of epinephrine administration was associated with patient outcomes after pediatric OHCA.Design, Setting, and ParticipantsThis cohort study included pediatric patients (&amp;lt;18 years) with OHCA treated by emergency medical services (EMS) from April 2011 to June 2015. Eligible patients were identified from the Resuscitation Outcomes Consortium Epidemiologic Registry, a prospective OHCA registry at 10 sites in the US and Canada. Data analysis was performed from May 2021 to January 2023.ExposuresThe main exposures were prehospital intravenous or intraosseous epinephrine administration and the interval between arrival of an advanced life support (ALS)–capable EMS clinician (ALS arrival) and the first administration of epinephrine.Main Outcomes and MeasuresThe primary outcome was survival to hospital discharge. Patients who received epinephrine at any given minute after ALS arrival were matched with patients who were at risk of receiving epinephrine within the same minute using time-dependent propensity scores calculated from patient demographics, arrest characteristics, and EMS interventions.ResultsOf 1032 eligible individuals (median [IQR] age, 1 [0-10] years), 625 (60.6%) were male. 765 patients (74.1%) received epinephrine and 267 (25.9%) did not. The median (IQR) time interval between ALS arrival and epinephrine administration was 9 (6.2-12.1) minutes. In the propensity score–matched cohort (1432 patients), survival to hospital discharge was higher in the epinephrine group compared with the at-risk group (epinephrine: 45 of 716 [6.3%] vs at-risk: 29 of 716 [4.1%]; risk ratio, 2.09; 95% CI, 1.29-3.40). The timing of epinephrine administration was also not associated with survival to hospital discharge after ALS arrival (P for the interaction between epinephrine administration and time to matching = .34).Conclusions and RelevanceIn this study of pediatric patients with OHCA in the US and Canada, epinephrine administration was associated with survival to hospital discharge, while timing of the administration was not associated with survival.

AbstractElectrocatalytic hydrogenation (ECH) is a burgeoning strategy for the sustainable utilization of hydrogen. However, how to effectively suppress the competitive hydrogen evolution reaction (HER) is a big challenge to ECH catalysis. In this study, amine (NH2R)‐coordinated Pd nanoparticles loaded on carbon felt (Pd@CF) as a catalyst is successfully synthesized by a one‐step solvothermal reduction method using oleylamine as the reducing agent. An exceptional ECH reactivity on benzaldehyde is achieved on the optimal Pd@CF catalyst in terms of a high conversion (89.7%) and selectivity toward benzyl alcohol (89.8%) at −0.4 V in 60 min. Notably, the Faradaic efficiency for producing benzyl alcohol is up to 90.2%, much higher than that catalyzed by Pd@CF‐without N‐group (41.1%) and thecommercial Pd/C (20.9%). The excellent ECH performance of Pd@CF can be attributed to the enriched electrons on Pd surface resulted from the introduction of NH2R groups, which strengthens both the adsorption of benzaldehyde and the adsorbed hydrogen (Hads) on Pd, preventing the combination of Hads to form H2, that is, inhibiting the HER. This study gives a new insight into design principles of highly efficient electrocatalysts for the hydrogenation of unsaturated aldehydes molecules.

AbstractLearning is the cornerstone of the growth and development of human beings. However, traditional learning methods are insufficient to meet the explosive growth of knowledge and information. Repeated training accounts for a large proportion of learning time, which significantly limits the improvement of learning efficiency. Inspired by cloud storage technology, electronic neurons (E‐neuron) with functions similar to neurons in the brain are proposed. Implanted E‐neurons can form new patterns of neural activity in circuits, including both E‐neurons and biological neurons, which can transfer knowledge from electronic cloud devices to human beings without training. Herein, the feasibility of this concept is preliminarily demonstrated. Fiber neural electrodes (FNEs) made of poly(3,4‐ethylene dioxythiophene) (PEDOT) modified carbon nanotubes (CNTs) are used to form both dendrites and axons of E‐neuron. After the implantation of an E‐neuron in a mouse's brain, an electrical neural connection is created between the mitral cell and dorsolateral periaqueductal gray (dlPAG). A piece of knowledge similar to “The red light stops; the green light is all right.” is then passed on to the mouse.

AbstractElectrochromic materials play a key role in smart windows, displays or anti‐glare rear‐view mirrors. Tungsten oxide is an intensely studied representative due to its extraordinary coloring performance. For commercial use, however, further optimization of the general cycle stability as well as the protection against external factors, such as moisture, is a still ongoing focus of research. In this study, the stabilization of the electrochromic switching performance of tungsten oxide is investigated using an ultrathin optimized Al2O3 protective coating, grown by atomic layer deposition. Amorphous tungsten oxide (a‐WOx) thin films are prepared by reactive radio‐frequency sputtering. The composition as well as electronic structure of the pure a‐WOx films is studied by X‐ray photoelectron spectroscopy. The electrochromic properties of the multilayer system are investigated in a nonaqueous electrolyte as well as in an electrolyte containing 10 vol% water. On the basis of these results, the stabilizing effect on the electrochromic switching characteristics of a‐WOx by the use of the additional thin Al2O3 protective layer is evident. It is shown that degradation and ageing of a‐WOx due to moisture can be prevented and coloration efficiencies of 50.4 cm2 C−1 can be achieved at 630 nm.
Estimating fertility using adults: A method for under‐enumerated pre‐adult skeletal samples

Published: March 2023

AbstractObjectivesInfant underrepresentation poses a great risk to accurate palaeodemographic findings when analyzing skeletal samples. Empirically derived palaeodemographic methods all require unbiased or minimally biased pre‐adult representation for estimating demographic characteristics, including fertility. Currently, there are no reliable methods for estimating palaeodemographic parameters when pre‐adults are underrepresented in skeletal samples, consequently such samples are often excluded from palaeodemographic analyses. The aim of this article is to develop a method for estimating total fertility rate (TFR) using reproductive aged adults, specifically for samples with suspected pre‐adult under‐enumeration.MethodologyUnited Nations mortality data and TFR from the World Population Prospects was utilized. The correlation between known fertility and the proportion of individuals in key reproductive years (15–49 years) to total adult sample (15+ years) was assessed as an indirect means to estimate fertility.ResultsIt was determined that the proportion of reproductive aged adults is a reasonable proxy for fertility. A significant positive correlation was observed between the TFR and those who died aged 15–49 years of age as a proportion of those who died ≥15 years (D15‐49/D15+). SE of the estimate revealed reasonable predictive accuracy. When applied to two modern non‐agricultural populations, the method showed some variability in accuracy but good potential for an improved outcome over existing methods when pre‐adults are underrepresented.ConclusionThis research has provided a new method for estimating fertility in archeological skeletal samples with pre‐adult under‐enumeration. In combination with a contextually focused approach, this provides a significant step toward further use of biased samples in palaeodemography.
