Authors: Havryliuk N. , Medvid Ya.
Published: August 2021

Goal. Determine the dominant species of ground beetles in crops of spring wheat with different fertilization systems and study the seasonal dynamics of the number of ground beetles.

Methods. The research was conducted in 2017—2019 years on the experimental field of NSC «Institute of Agriculture of NAAS of Ukraine» in department of plant protection from pests and diseases. Accounting of carabids fauna in accordance with the generally accepted methodology, mainly using Barber soil traps. The ecological characteristics are given using literature data.

Results. Specified species composition of the dominant species of carabids in spring wheat crops under different fertilization systems. Represented the seasonal quantity dynamics of mass species of carabids (Bembidion properans S., Harpalus affinis S., Harpalus rufipes D., Poecilus cupreus L., Harpalus distinguendus D.) with mineral (N90P60K90) and organic (with plowing of by-products of the predecessor) fertilizer systems. Population peaks on spring wheat reached maximums in May due to an increase in the activity of species of the spring-summer group of ground beetles (Bembidion properans S., Harpalus distinguendus D., Poecilus cupreus L.), in June — July — due to the summer-autumn group (Harpalus rufipes D. and Harpalus affinis S).

Conclusions. The peak activity of carabids in different areas is due to the peculiarities of the biology of each species during the growing season of spring wheat and weather conditions. Of the dominant, the most widespread species with mineral fertilizers was Bembidion properans S., with organic — Harpalus affinis S. There is a difference in the trophic specialization of beetles. In the areas with mineral fertilizer, the number of zoophages and myxophytophages was almost at the same level — 33.4 and 36.6 %, respectively. Organic fertilizer was dominated by myxophytophagous carabids (44%) with a mixed type of diet due to the largest number of species and the number of the genus Harpalus, the percentage of zoophagous was 14.5 %.

Published: August 2021

Este estudo analisa os sentidos de motivação, para alunos do ensino médio, sobre o pluralismo didático em aulas de biologia. O objetivo foi compreender como a motivação discente pode ser afetada por essa pluralidade de atividades. Para isso, foi realizada uma pesquisa-ação, com seis alunos, em 21 encontros, em que as informações foram coletadas mediante questionários, registros sobre cada atividade e observação das aulas. Com este trabalho, compreendeu-se que a motivação não está desconectada de um objetivo, podendo haver discordância entre as metas do professor e as metas dos alunos, ponto crucial no entendimento do cenário educativo do ensino médio atual. Nesse intuito, é necessário o planejamento educacional, em consonância com a realidade em que os alunos estão inseridos. Avaliamos que houve motivação discente com a pluralidade didática, porém, destacamos que essa motivação foi alcançada por meio da variação de estratégias e pelo ambiente social estabelecido nessas aulas. Assim, podemos concluir que a motivação não é inata, mas, sim, uma construção subjetiva dos sujeitos envolvidos nesse cenário.

Os resultados demonstraram que as dificuldades relatadas pelos professores na abordagem dessa temática são semelhantes entre os grupos, que apontaram como maior desafio as famílias ausentes ou muito permissivas quanto à sexualidade, e como assuntos mais difíceis de serem abordados, a homossexualidade, a masturbação e a violência sexual.
Reflexões sobre a relação museu-escola: na direção de um museu permeável
Authors: Soares Ozias de Jesus
Published: August 2021

Atualmente, museus e escolas têm realizado esforços no sentido de um trabalho articulado. Todavia, notamos que essa perspectiva ainda não se tornou hegemônica. Os condicionantes estruturais da gênese dos museus e os modelos de gestão e de educação permanecem como um desafio a um trabalho numa outra direção. Como instituição de saber, de conhecimento, de memória e cultura, tais instituições possuem ricas possibilidades como agências de transformação social. O horizonte da formação integral emerge como pilar fundamental para pensar a conjunção museu-escola. A permeabilidade de ambas as instituições deve ser buscada como forma de romper com os tradicionais muros que os separam.

Published: August 2021

Este trabalho sintetiza os dados de uma pesquisa qualitativa-interpretativa, por meio da qual se buscou identificar as percepções de alunos de pós-graduação stricto sensu acerca do “multiletramento” e seus possíveis impactos no ensino. Após análise de suas afirmações, coletadas por meio de questionário, constatou-se que, oriundos de múltiplas áreas de conhecimento, esses alunos atrelam o conceito tanto à multiplicidade de linguagens quanto a um novo contexto de ensino-aprendizagem, em que novas práticas pedagógicas são exigidas. Isso evidencia o modo como interagem com acepções teóricas, imprescindíveis para o desenvolvimento de suas pesquisas, balizadas pela proposta do programa de pós-graduação que integram.

Published: August 2021

Este artigo apresenta uma análise do Projeto Pedagógico de Curso do Bacharelado em Engenharia Mecânica do Instituto Federal de Educação, Ciência e Tecnologia da Bahia – IFBA – Campus de Salvador, aprovado em 2019, comparando-o com sua versão anterior, no aspecto da inclusão de pessoas com deficiência. Foram feitos estudos bibliográficos sobre currículo e legislação que tratam da inclusão, revisão de literatura sobre estudos que analisaram PPC de cursos superiores, sobretudo da engenharia, e documentos internos da instituição. Há um aumento no número de pessoas com deficiência no ensino superior no Brasil e na Bahia, mas existem vagas de trabalho que não são preenchidas, por falta de mão de obra qualificada que possua algum tipo de deficiência. A atual versão do PPC atende à legislação vigente e inclui todos os documentos institucionais que tratam de acessibilidade. A atualização de um PPC, além de alinhar o documento à uma legislação, visa a promover um ambiente inclusivo de fato.
Marcos legais da Educação Ambiental em Petrópolis (RJ): conquistas e retrocessos
Authors: Novicki Victor de Araujo , Farjalla Ramiro
Published: August 2021

Este artigo objetiva, inicialmente, analisar como a temática ambiental é tratada na Lei Orgânica Municipal (LOM) e no Plano Municipal de Educação (PME) de Petrópolis, município do estado do Rio de Janeiro (RJ), enfatizando as concepções de meio ambiente, de desenvolvimento sustentável e de Educação Ambiental (EA) e, num segundo momento, desenvolver uma análise comparativa entre as políticas nacional, fluminense e petropolitana de EA. Conclui-se que poucas conquistas da EA crítica foram incorporadas à LOM ou ao PME. Apesar da política municipal de EA incorporar abordagens críticas das outras políticas, cabe destacar algumas ausências: (a) não trata da formação inicial e continuada de professores; (b) não cria órgão específico para coordenar o programa municipal de EA, nem incorpora a participação social nesse processo; (c) não inclui especificidades da rede de ensino ou dos problemas socioambientais locais.

PADRÕES GEOMÉTRICOS E FIGURAIS: UMA ANÁLISE EM LIVROS DIDÁTICOS DE MATEMÁTICA DO ENSINO FUNDAMENTAL
Authors: Fernandes Dienifer Ferner , Soares Maria Arlita Da Silveira , Borba Cleber Massirer
Published: August 2021

Este texto tem por objetivo apresentar a análise das versões aprovadas nos PNLD/2017 e PNLD/2020 de uma coleção de livros didáticos de Matemática do Ensino Fundamental quanto a abordagem de padrões geométricos e figurais. Para tanto, buscou-se referências em pesquisas sobre desenvolvimento do pensamento algébrico e documentos curriculares (Base Nacional Comum Curricular, Parâmetros Curriculares Nacionais). A opção metodológica foi de uma pesquisa qualitativa na forma de análise documental. A análise dos dados permitiu concluir que, os padrões geométricos e figurais são abordados em raras situações nos livros didáticos analisados e na maioria das situações estão localizados nas sessões especiais das obras, indicando que os padrões não foram tomados como ponto de partida para a aprendizagem de conteúdos/conceitos matemáticos, em particular, conceitos algébricos. Sublinha-se que, muitos dos padrões verificados em ambas as versões da coleção foram utilizados para retomar e/ou ampliar o estudo da operação de potenciação. Ressalta-se que são pouquíssimas as situações que envolvem padrões figurais ou geométricos que mobilizam as três fases de um padrão. Assim, os professores que visam propor atividades para o desenvolvimento do pensamento algébrico não devem limitar-se as situações propostas nas coleções analisadas.

Authors: Morales Sánchez Mario Alberto
Published: August 2021

Resumen: Partiendo del marco teórico de la economía evolutiva, en este trabajo se realiza un análisis sobre la migración de talento laboral entre las distintas subramas de la industria manufacturera. Se hace una comparación del caso mexicano con el mundo, para determinar cuáles son las principales ramas atractoras y expulsoras de trabajo. Para ello se utilizan datos proporcionados por el Banco Mundial en alianza con LinkedIn, Digital Data for Development, y se emplea la teoría de grafos como metodología para el análisis de estos. La principal aportación radica en establecer cuáles son las ramas manufactureras que son atractoras de empleo en México y a nivel mundial y cuales aquellas que han tenido una pérdida neta en los últimos 5 años. En términos prospectivos este análisis puede contribuir con el desarrollo de políticas industriales enfocadas a las ramas dinámicas de la economía mundial.
¿Desindustrialización prematura? El caso de Nuevo León, México
Authors: Vásquez Galán Belem Iliana , Corrales Corrales Salvador
Published: August 2021

El objetivo del artículo es analizar el proceso de desindustrialización ocurrida en la industria nacional mexicana y en particular en la de Nuevo León en el periodo 1993-2016. Se calculó la participación de la industria manufacturera en la creación de valor agregado real y empleos, la velocidad del cambio estructural y el ingreso per cápita para identificar el momento y naturaleza de la desindustrialización. Se encontró una desindustrialización prematura iniciada a finales de los noventa con el cambio estructural desfavorable ocurrido por la caída de la participación industrial en la economía y los bajos ingresos per cápita. A diferencia de la experiencia nacional, en Nuevo León se gestó una desindustrialización natural resultado de la evolución de su industria, de tradicional (vidrio, acero y cemento) a moderna (eléctrica y electrónica y automotriz) y que sentó las bases para transitar a una economía terciaria.

Published: August 2021

La pandemia por la COVID-19 ha afectado de manera crítica la vida cotidiana, dentro y fuera de Cuba. Para la Isla, esto ha venido acompañado de un agravamiento de las condiciones socioeconómicas generales por el recrudecimiento del embargo impuesto por los E.E.U.U., el detrimento del sector turístico y las exportaciones, la carencia de divisas, agudización del desabastecimiento que irremediablemente conduce al encarecimiento de los productos de primera necesidad que permanecen disponibles. No obstante, la vida en La Mayor de las Antillas ha sido sometida a modificaciones facilitadas en gran medida, por las nuevas tecnologías. Así como al mundo virtual se le asocian buenas prácticas como el activismo, también se le atañen otras que atentan contra el bienestar de los usuarios: ciberacoso, adicción a internet, etc. El objetivo que se persigue por medio de la socialización de estas nuevas prácticas para la sociedad cubana, es visibilizar la adaptabilidad de las culturas juveniles e identificar las potencialidades y amenazas del entorno infocomunicativo en este contexto.

Digital man as a philosophical problem
Authors: DZOBAN O.
Published: August 2021

It is proposed to consider a digital person as the latest stage of human development as a major object and subject of information relations in the information society at the latest stages of its development; as a postmodern type of a homo sapiens capable of processing information, creating new information phenomena, interconnections and structures. It is substantiated that the transition to a digital person occurred due to convergence of technologies of artificial intelligence, machine training and powerful databases capable of using an unlimited amount of information for its processing, classification and multiple use. The attention is drawn to the fact that a digital person is, first of all, a person of new moral values, which immerses in the virtual reality of simulations and increasingly perceives the world as a digital game environment, realizing its conventionality, controllability of its parameters and the possibility of exiting it.
Legal principles of countering hate speech: a retrospective review and analysis of perspectives
Authors: GOLOVKO O.
Published: August 2021

The article reflects the retrospective review of Ukrainian legislation and an analysis of the prospects of the lawmaking process on countering hate speech, including in the media space. Criteria for the hate speech and other non-criminal criminal qualification, which entail legal liability or without one, are presented. The conclusions are drawn from the European practice of classifying hate crimes. It has been established that the basis of legislation to combat hate speech should be recognition of the highest social value of a person, regardless of those features that make him or her unlike any other. The problems of new draft laws aimed at counteracting hate speech in the media space have been identified.

The Complex Organic Molecular Content in the L1498 Starless Core
Authors: Jiménez-Serra Izaskun , Vasyunin Anton I. , Spezzano Silvia , Caselli Paola , Cosentino Giuliana , Viti Serena
Published: August 2021

Observations carried out toward starless and prestellar cores have revealed that complex organic molecules are prevalent in these objects, but it is unclear what chemical processes are involved in their formation. Recently, it has been shown that complex organics are preferentially produced at an intermediate-density shell within the L1544 prestellar core at radial distances of ∼4000 au with respect to the core center. However, the spatial distribution of complex organics has only been inferred toward this core, and it remains unknown whether these species present a similar behavior in other cores. We report high-sensitivity observations carried out toward two positions in the L1498 starless core, the dust peak and a position located at a distance of ∼11,000 au from the center of the core where the emission of CH3OH peaks. Similarly to L1544, our observations reveal that small O-bearing molecules and N-bearing species are enhanced by factors of ∼4–14 toward the outer shell of L1498. However, unlike L1544, large O-bearing organics such as CH3CHO, CH3OCH3, or CH3OCHO are not detected within our sensitivity limits. For N-bearing organics, these species are more abundant toward the outer shell of the L1498 starless core than toward the one in L1544. We propose that the differences observed between O-bearing and N-bearing species in L1498 and L1544 are due to the different physical structure of these cores, which in turn is a consequence of their evolutionary stage, with L1498 being younger than L1544.

We report 40–139 keV in situ ion measurements from the Voyager 1/Low Energy Charged Particle (LECP) instrument, over the time period from 2000 to the first 3 months of 2020, toward assessing energetic ion flow properties inside the heliosheath (HS) and upstream of the heliopause (HP). We identify an average radial outflow of ions at ∼46, 67, and 109 keV of ∼2.33 × 10−3, ∼1.37 × 10−3, and ∼7.27 × 10−4

–1, respectively, from the beginning of 2013 up to 2020, i.e., over a spatial range of ∼28 au past the HP. The raw 40–139 keV rates, uncorrected for background, show distinct intensity dropouts for particles with 90° pitch angles, in concert with the >211 MeV Galactic cosmic-ray anisotropy events, reported after Voyager 1 exited the HS in 2012 August. The intensity spectrum is consistent with a power-law form in energy with a spectral index of ∼−1.4, similar to energy spectra measured by both Voyager 1 and 2/LECP inside the HS, providing strong indication that these particles correspond to an ion population leaking from the HS into interstellar space, most likely due to the flux tube interchange instability at the boundary. Future modeling efforts should incorporate this ion population, which provides the framework for establishing a communication between the HS and the very local interstellar medium.

We present follow-up photometry and spectroscopy of ZTF J0328−1219, strengthening its status as a white dwarf exhibiting transiting planetary debris. Using TESS and Zwicky Transient Facility photometry, along with follow-up high-speed photometry from various observatories, we find evidence for two significant periods of variability at 9.937 and 11.2 hr. We interpret these as most likely the orbital periods of different debris clumps. Changes in the detailed dip structures within the light curves are observed on nightly, weekly, and monthly timescales, reminiscent of the dynamic behavior observed in the first white dwarf discovered to harbor a disintegrating asteroid, WD 1145+017. We fit previously published spectroscopy along with broadband photometry to obtain new atmospheric parameters for the white dwarf, with M
⋆ = 0.731 ± 0.023 M
⊙, T
eff = 7630 ± 140 K, and [Ca/He] = − 9.55 ± 0.12. With new high-resolution spectroscopy, we detect prominent and narrow Na D absorption features likely of circumstellar origin, with velocities 21.4 ± 1.0 km s−1 blueshifted relative to atmospheric lines. We attribute the periodically modulated photometric signal to dusty effluents from small orbiting bodies such as asteroids or comets, but we are unable to identify the most likely material that is being sublimated, or otherwise ejected, as the environmental temperatures range from roughly 400 to 700 K.
The Critical Dark Matter Halo Mass for Population III Star Formation: Dependence on Lyman–Werner Radiation, Baryon-dark Matter Streaming Velocity, and Redshift
Authors: Kulkarni Mihir , Visbal Eli , Bryan Greg L.
Published: August 2021

A critical dark matter halo mass (M
crit) for Population III stars can be defined as the typical minimum halo mass that hosts sufficient cold-dense gas required for the formation of the first stars. The presence of Lyman–Werner (UV) radiation, which can dissociate molecular hydrogen, and the baryon-dark matter streaming velocity both delay the formation of Population III stars by increasing M
crit. In this work, we constrain M
crit as a function of Lyman–Werner flux (including self-shielding), baryon-dark matter streaming, and redshift using cosmological simulations with a large sample of halos utilizing the adaptive mesh refinement code enzo. We provide a fit for M
crit as a function of these quantities, which we expect to be particularly useful for semi-analytical models of early galaxy formation. In addition, we find (i) the measured redshift dependence of M
crit in the absence of radiation or streaming is (1 + z)−1.58, consistent with a constant virial temperature; (ii) increasing the UV background increases M
crit while steepening the redshift dependence, up to (1 + z)−5.7; (iii) baryon-dark matter streaming boosts M
crit but flattens the dependence on redshift; (iv) the combination of the two effects is not simply multiplicative.

Published: August 2021

La notion de groupe syntaxique, reconnue par le distributionalisme et exploitée par toutes les théories modernes, en particulier par la grammaire générative, s’est vite avérée indispensable dans les études syntaxiques. Les projets de rénovation des années 1970 l’ont introduite dans le domaine didactique lorsqu’il s’est agi d’exploiter les acquis de la linguistique. L’accent a alors été mis sur la nouvelle façon d’observer la phrase, de découvrir les constructions et leur fonctionnement, sur la démarche à suivre, sans justifier les groupes, tant leur nécessité est admise. Or il est facile de constater que cette notion n’a jamais été vraiment bien intégrée ni correctement prise en compte en didactique du français langue maternelle. C’est cette lacune méthodologique dans la transposition didactique que l’étude analyse, en examinant d’abord le statut de la notion de groupe dans les textes officiels et dans les manuels, puis en interrogeant les raisons et les conséquences de cet échec.
La phrase écrite en formation initiale des enseignants de français-lettres du secondaire
Authors: Gerlaud Béatrice
Published: August 2021

La phrase traverse les siècles et berce l’apprentissage de la langue : du primaire au supérieur elle ne cesse d’être objet de commentaires critiques. Pourtant, entre la « belle » phrase lue voire modélisée des auteurs et les réalisations langagières des élèves, la discordance est fréquente. Et l’étude de la phrase canonique des grammairiens construite autour d’un élément recteur n’y change rien. Comment ce savoir savant est-il mobilisé chez les enseignants stagiaires encore tout « imprégnés » des grammaires de référence pour passer les concours d’entrée dans l’enseignement ? Leur confrontation à des « phrases » d’élèves, change-t-elle leurs conceptions et représentations ? L’étude analyse quarante-huit définitions données par des enseignants débutants. Si ces définitions mettent en avant la prégnance de l’héritage grammatical scolaire, celui-ci est peu entamé par la formation universitaire plus récente ; elles suggèrent cependant des niveaux d’intervention en formation initiale et au-delà dans l’exercice du métier.
Pour une dynamique de l’enseignement grammatical
Authors: Taous Tatiana
Published: August 2021

Pour tenter de lutter contre un enseignement figé de la grammaire, la présente étude se propose d’opposer aux leçons et synthèses traditionnelles des supports qui se veulent dynamiques dans leur conception de la notion grammaticale traitée. À partir de supports existants (disponibles sur le marché ou sur la toile), l’analyse révèle le caractère limitatif et, de fait, non fonctionnel de ces derniers. L’alternative proposée se présente comme une analyse préliminaire à destination des professionnels (enseignants ou formateurs) et s’inscrit dans une tradition linguistique bien avérée, qui aspire à décrire les faits de langue selon les différents domaines linguistiques. Les notions grammaticales abordées se veulent progressives : elles partent des classes grammaticales, avant de se fixer plus précisément sur la préposition et le verbe.
La terminologie grammaticale de 2020 : quelles notions lexicales pour quelle mise en œuvre ?
Authors: Dupuy Catherine , Genre Stéphanie
Published: August 2021

La récente Terminologie grammaticale publiée en juillet 2020 se donne pour objectif de fournir aux enseignants des premier et second degrés un socle théorique commun, tout en se présentant comme un guide pour l’enseignement. L’étude interroge les choix opérés par ses concepteurs, tant du point de vue de la distribution des notions sélectionnées que de certaines définitions données (lexique, vocabulaire, collocations, etc.). La lecture critique de cette terminologie prend appui sur les enjeux théoriques et méthodologiques énoncés par la didactique du lexique. L’analyse propose ensuite une redistribution par couplage de certains termes (lexique vs vocabulaire ; champ sémantique et polysémie ; champ lexical vs champ sémantique ; champ lexical vs champ thématique), afin d’en montrer l’intérêt pour l’étude du lexique, l’apprentissage du vocabulaire et plus largement l’enseignement du français.
Des personnes réelles dans l’autofiction
Authors: Baudelle Yves
Published: August 2021

Dans l’autofiction stricto sensu  – roman où A = N = P –, la question des personnes réelles est inséparable de l’onomastique, ce qui conduit à distinguer deux groupes obéissant à deux régimes de textualité : les proches de l’auteur – inconnus – et les célébrités. Globalement soustraite aux procédures de vérification et même privée de certification onomastique, l’identification des premiers reste conjecturale. Dans le cas des célébrités, au contraire, les noms valident la référence, qui n’est pas subordonnée à leur degré de fictionnalisation. Constatant que la notoriété des personnages procède désormais de la sphère médiatique, l’étude se demande, pour finir, si le roman people n’est pas la forme spécifique de l’autofiction contemporaine.
Comment lire les fictions racontant la vie de personnes réelles ? Lecture située et « vérité littéraire »
Authors: Zenetti Marie-Jeanne
Published: August 2021

À partir des polémiques suscitées par la diffusion de la quatrième saison de la série The Crown , cet article propose d’interroger les fictions de la personne réelle sous l’angle de leur réception, dans une perspective à la fois pragmatique et épistémique : que fait-on de la question de la vérité quand on lit ou qu’on regarde de telles fictions, censées raconter la vie de personnes réelles ? Il développe l’idée qu’elles invitent à pratiquer une « lecture située », c’est-à-dire prenant en considération la manière dont les contextes de réception d’une œuvre, qu’il s’agisse ou non d’une fiction, transforment les usages et les interprétations qui en sont faits.
« Chromo-culture ». Les danses de la nature de Loïe Fuller et la force énergétique de la lumière
Authors: Ronetti Alessandra
Published: August 2021

Les danses chromo-lumineuses, inventées en 1891 par l’Américaine Loïe Fuller, sont mises en relation dans cet article avec l’essor des théories psychologiques dix-neuvièmistes sur la force énergétique de la lumière colorée, dont l’ouvrage L’Esthétique de la lumière de Paul Souriau représente le point culminant. Alors que l’interprétation de la fonction biologique de la lumière sur les organismes vivants est développée à partir des études sur la chromothérapie de savants français et américains (à l’instar de la « chromo-culture » de Camille Flammarion), les féeries électriques de Loïe Fuller – qui projettent des lumières colorées en mouvement sur le corps de la danseuse mimant des formes végétales et animales – misent sur le même processus d’éclairage propre à la chromothérapie, afin d’affecter directement le spectateur.
Une forme de biographie chorégraphiée par le fragment. Autour de Degas Danse Dessin de Paul Valéry
Authors: Kisiel Marine
Published: August 2021

Lorsqu’il publie Degas Danse Dessin en 1936, Paul Valéry revient sur l’amitié qui l’a lié à Edgar Degas. Son texte, placé sous le signe de la discontinuité et de l’agrégation, est tout d’abord publié en feuilles, et s’annonce aussitôt comme « une manière de monologue » où Valéry promet d’égrener souvenirs et réflexions. De fait, l’ouvrage dessine un véritable pas de deux entre Valéry et Degas, le texte et l’image, le dessin et la danse, où l’art du peintre et les mécanismes de la création sont associés par l’auteur à une « danse sacrée », et le dessin, compris comme une suite de signes, à une écriture et à un langage que Valéry s’emploie à décrypter. Cet essai s’attache à analyser comment le DDD , sorte de biographie chorégraphiée par le fragment, noue entre elles deux formes de création – celle de Degas, celle de Valéry – et analyse, à travers la « danse du peintre », celle de l’esprit que Valéry place au cœur de tout.
Aux origines de la zoopoétique contemporaine : le poète romantique face à l’animal (Lamartine, Nerval, Hugo)
Authors: Kekus Filip
Published: August 2021

Si on peut se féliciter de l’émergence de la zoopoétique, on peut regretter qu’elle se soit peu ressourcée à son substrat romantique, et lorsqu’elle l’a été, qu’elle se soit pour beaucoup restreinte à la prose. L’article entend contribuer à combler cette lacune en montrant combien la poésie romantique, et en particulier celle de Lamartine, de Nerval et de Hugo, cherche à nouer un dialogue original avec l’animal dans le cadre de la querelle du panthéisme.
Global dynamics and bifurcations in a SIRS epidemic model with a nonmonotone incidence rate and a piecewise-smooth treatment rate
Authors: Pan Qin , Huang Jicai , Huang Qihua
Published: August 2021

In this paper, we analyze a SIRS epidemic model with a nonmonotone incidence rate and a piecewise-smooth treatment rate. The nonmonotone incidence rate describes the "psychological effect": when the number of the infected individuals (denoted by \begin{document}$ I $\end{document}) exceeds a certain level, the incidence rate is a decreasing function with respect to \begin{document}$ I $\end{document}. The piecewise-smooth treatment rate describes the situation where the community has limited medical resources, treatment rises linearly with \begin{document}$ I $\end{document} until the treatment capacity is reached, after which constant treatment (i.e., the maximum treatment) is taken.Our analysis indicates that there exists a critical value \begin{document}$ \widetilde{I_0} $\end{document} \begin{document}$ ( = \frac{b}{d}) $\end{document} for the infective level \begin{document}$ I_0 $\end{document} at which the health care system reaches its capacity such that:(i) When \begin{document}$ I_0 \geq \widetilde{I_0} $\end{document}, the transmission dynamics of the model is determined by the basic reproduction number \begin{document}$ R_0 $\end{document}: \begin{document}$ R_0 = 1 $\end{document} separates disease persistence from disease eradication. (ii) When \begin{document}$ I_0 < \widetilde{I_0} $\end{document}, the model exhibits very rich dynamics and bifurcations, such as multiple endemic equilibria, periodic orbits, homoclinic orbits, Bogdanov-Takens bifurcations, and subcritical Hopf bifurcation.

Published: August 2021

In this paper, we study the long-time dynamics of a system modelinga mixture of three interacting continua with nonlinear damping, sources terms and subjected to small perturbations of autonomousexternal forces with a parameter \begin{document}$ \epsilon $\end{document}, inspired by the modelstudied by Dell' Oro and Rivera [12]. We establish astabilizability estimate for the associated gradient dynamicalsystem, which as a consequence, implies the existence of a compactglobal attractor with finite fractal dimension andexponential attractors. This estimate is establishedindependent of the parameter \begin{document}$ \epsilon\in[0,1] $\end{document}. We also prove thesmoothness of global attractors independent of the parameter\begin{document}$ \epsilon\in[0,1] $\end{document}. Moreover, we show that the family of globalattractors is continuous with respect to the parameter \begin{document}$ \epsilon $\end{document} ona residual dense set \begin{document}$ I_*\subset[0,1] $\end{document} in the same sense proposed inHoang et al. [15].
Practical partial stability of time-varying systems
Authors: Hamzaoui Abdelfettah , Taieb Nizar Hadj , Hammami Mohamed Ali
Published: August 2021

In this paper we investigate the practical asymptotic and exponential partial stability of time-varying nonlinear systems. We derive some sufficient conditions that guarantee practical partial stability of perturbed systems using Lyapunov's theory where a converse theorem is presented. Therefore, we generalize some works which are already made in the literature. Furthermore, we present some illustrative examples to verify the effectiveness of the proposed methods.
