Traditional paradigm and progressivism of contemporary paradigm in early and preschool education
Authors: Pintar Željka
Published: December 2020

Historical changes in pedagogical ideas and orientations that underpin them show that pedagogy orientates towards the general course of social development. Each historical period creates an interpretative framework for children upbringing. Interpretations of educational concepts depend on the political-economic context of community life, general philosophy advocated by society, and the characteristics of development of various scientific disciplines. Taking into account the social context, pedagogical paradigm is conceptualized by creating authentic scientific knowledge and accepting the knowledge of complementary sciences. This paper discusses similarities and differences between traditional and contemporary pedagogical paradigms in relation to the context of early and preschool education. It also highlights scientific assumptions, starting points and studies of the disciplines with which the contemporary educational paradigm shares the same subject of interest, and through which it conceives and underpins its educational approach. It also problematizes introduction of contemporary educational concepts into practice of early and preschool education. The aforementioned allows focusing on the way in which contemporary pedagogical concept represents its authentic approach, how its principles depart, and in what way they continue on pre-established pedagogical practices.

EVIDENCE-BASED PRACTICES THAT DEAL WITH WORK-FAMILY CONFLICT AND ENRICHMENT: SYSTEMATIC LITERATURE REVIEW
Authors: Vadvilavičius Tadas , Stelmokienė Aurelija
Published: December 2020

Work and family are the most important aspects in everyday life that interact with each other simultaneously. The interaction between work and family may cause both negative and positive outcomes that is why scientists and practitioners are seeking to understand how to control them. The purpose of this article was to review existing literature on work-family conflict and enrichment interventions. We conducted a systematic literature review to investigate the evidence-based practises that dealt with reduction of work-family conflict and increase in work-family enrichment. After the screening, 12 articles from 699 unique studies were selected for the in-depth analysis. 11 out of 12 represented interventions confirmed significant positive results about the reduction of work-family conflict or increase in work-family enrichment. It is not surprising that organizations quite often choose training/workshop as the most suitable intervention. Similarly, only one scientific article presented the intervention that used real organizational change to reduce work-family conflict. Additionally, only one intervention was oriented towards the positive side of work family interaction – increase in work-family enrichment. Finally, practical implications and future research directions are proposed in the discussion.
THE ROLE OF SUSTAINABLE FINANCE IN ACHIEVING SUSTAINABLE DEVELOPMENT GOALS: DOES IT WORK?
Authors: Ziolo Magdalena , Bak Iwona , Cheba Katarzyna
Published: December 2020

The World Bank and International Monetary Fund reported that the achievement of the 17 Sustainable Development Goals (SDGs) requires an escalation of development finance. The report Scaling Finance for the Sustainable Development Goals highlighted the urgency of the efforts to realize SDGs in encouraging financial innovation to move quickly. Even if the role of finance in achieving SDGs is unquestionable, few scientific studies have addressed these issues. We tried to fill the existing research gap. In this study, we examined the link between sustainable finance and SDGs based on European Union countries belonging to the OECD. We present a new and the original research approach. We assumed that the sustainable finance model plays a fundamental role in implementing SDGs (all SDGs were analysed except for SDG 6 and SDG14, due to lack of statistics were not analysed) and ensuring that social and environmental sustainability are reflected in SDGs. The results of this study show that the more sustainable the finance model, the better the achievement of SDGs in the group of analysed countries. We found a strong link between sustainable finance model and social sustainability (SDG1, 3, 4, 5, 10, 16); environmental sustainability (SDG11, 12, 13, 15) and economic sustainability (SDG8, 9, 17).

Analysis of new precision radial velocity (RV) measurements from the Lick Automated Planet Finder and Keck HIRES has yielded the discovery of three new exoplanet candidates orbiting the nearby stars HD 190007 and HD 216520. We also report new velocities from the APF and the Planet Finder Spectrograph and updated orbital fits for the known exoplanet host stars GJ 686 and HD 180617. Of the newly discovered planets, HD 190007 b has a period of P = 11.72 days, an RV semiamplitude of K = 5.64 ± 0.55 m s−1, a minimum mass of M
pl = 16.46 ± 1.66 M
⊕, and orbits the slightly metal-rich, active K4V star HD 190007. For HD 216520 b, we find P = 35.45 days, K = 2.28 ± 0.20 m s−1, and M
pl = 10.26 ± 0.99 M
⊕, while for HD 216520 c, P = 154.43 days, K = 1.29 ± 0.22 m s−1, and M
pl = 9.44 ± 1.63 M
⊕. Both planets orbit the slightly metal-poor, inactive K0V star HD 216520. Our updated best-fit models for HD 180617 b and GJ 686 b are in good agreement with the published results. For HD 180617 b, we obtain P = 105.91 days and M
pl = 12.214 ± 1.05 M
⊕. For GJ 686 b, we find P = 15.53 days and M
pl = 6.624 ± 0.432 M
⊕. Using an injection-recovery exercise, we find that HD 190007 b and HD 216520 b are unlikely to have additional planets with masses and orbital periods within a factor of 2, in marked contrast to ∼85% of planets in this mass and period range discovered by Kepler.
Estimation of Thermal and Epithermal Neutron Fluences at the Lunar Surface from Isotopic Compositions of Rare Earth Elements
Authors: Hidaka Hiroshi , Mizutani Yuki , Yoneda Shigekazu
Published: December 2020

Thermalized neutrons arising at the surface of solar planets are produced from the interaction of cosmic rays with the nucleus consisting of surficial materials. The neutron energy spectrum in the range between thermal and epithermal regions at the lunar surface was investigated based on the combination of the isotopic variations of Sm and Gd caused by the thermal neutron-capture reactions in our previous study, with those of Dy, Er, and Yb caused by the epithermal neutron-capture reactions in this study. The detailed comparison of the systematic isotopic variations among Sm, Gd, Dy, Er, and Yb helps to construct a neutron energy spectrum at the surface of the Moon. Seven kinds of lunar soils at different depths of the drill core recovered from the Apollo 15 landing site (A-15) were used in this study. Isotopic variations of 164Dy/161Dy, 168Er/167Er, and 168Yb/174Yb were newly found in the A-15 samples, and showed the depth dependence caused by the interaction with cosmic-ray irradiation. In particular, the combination of the isotopic shifts of 168Er/167Er and 150Sm/149Sm could be effectively used to evaluate the epithermal neutron fluences of 5.4–8.1 × 1017 n cm−2 that were more than 10 times higher than thermal neutron fluences of 0.48–0.69 × 1017 n cm−2 reestimated in this study.
Broadband Selection, Spectroscopic Identification, and Physical Properties of a Population of Extreme Emission-line Galaxies at 3 < z < 3.7*

We present the selection, spectroscopic identification, and physical properties of extreme emission-line galaxies (EELGs) at 3 < z < 3.7, aiming at studying physical properties of an analog population of star-forming galaxies (SFGs) at the epoch of reionization. The sample is selected based on the excess in the observed Ks broadband flux relative to the best-fit stellar continuum model flux. By applying a 0.3 mag excess as a primary criterion, we select 240 EELG candidates with intense emission lines and estimated an observed-frame equivalent width (EW) of ≳1000 Å over the UltraVISTA-DR2 ultra-deep stripe in the COSMOS field. We then carried out HK-band follow-up spectroscopy for 23 of the candidates with Subaru/MOIRCS, and we find that 19 and 2 of them are at z > 3 with intense [O iii] emission and Hα emitters at z ≃ 2, respectively. These spectroscopically identified EELGs at z ≃ 3.3 show, on average, higher specific star formation rates (sSFRs) than the star-forming main sequence, low dust attenuation of E(B − V) ≲ 0.1 mag, and high [O iii]/[O ii]ratios of ≳3. We also find that our EELGs at z ≃ 3.3 have higher hydrogen-ionizing photon production efficiencies (ξ
ion) than the canonical value (≃1025.2 erg−1 Hz), indicating that they are efficient in ionizing their surrounding interstellar medium. These physical properties suggest that they are low-metallicity galaxies with higher ionizing parameters and harder UV spectra than normal SFGs, which is similar to galaxies with Lyman continuum (LyC) leakage. Among our EELGs, those with the largest [O iii]/[O ii] and EW([O iii]) values would be the most promising candidates to search for LyC leakage.
Coronal Electron Densities Derived with Images Acquired during the 2017 August 21 Total Solar Eclipse
Authors: Bemporad A.
Published: December 2020

The total solar eclipse of 2017 August 21 was observed with a digital single lens reflex (DSLR) camera equipped with a linear polarizing filter. A method was developed to combine images acquired with 15 different exposure times (from 1/4000 s to 4 s), identifying in each pixel the best interval of detector linearity. The resulting mosaic image of the solar corona extends up to more than 5 solar radii, with a projected pixel size of 3.7 arcsec/pixel and an effective image resolution of 10.″2, as determined with visible α-Leo and ν-Leo stars. Image analysis shows that in the inner corona the intensity gradients are so steep that nearby pixels show a relative intensity difference of up to ∼10%; this implies that care must be taken when analyzing single exposures acquired with polarization cameras. Images acquired with two different orientations of the polarizer have been analyzed to derive the degree of linear polarization and the polarized brightness pB in the solar corona. After intercalibration with pB measurements by the K-Cor instrument on Mauna Loa Solar Observatory (MLSO), the data analysis provided the 2D coronal electron density distribution from 1.1 up to ∼3 solar radii. The absolute radiometric calibration was also performed with the full Sun image and with magnitudes of visible stars. The resulting absolute calibrations show a disagreement by a factor of ∼2 with respect to MLSO; interestingly, this is the same disagreement recently found with eclipse predictions provided by MHD numerical simulations.
Four new species of Phrynidius Lacordaire (Coleoptera, Cerambycidae, Lamiinae) from Mexico with an identification key for the genus

Published: December 2020

Since the description of its eight species, the Mesoamerican genus Phrynidius Lacordaire (Cerambycidae, Lamiinae, Apomecynini) has not been comprehensively studied, with only a few distributional records published in recent years. In this work, four new species of Phrynidius are described from Chiapas, Mexico: P. cristinaesp. nov. from the municipality of Escuintla, P. diminutussp. nov. from San Cristobal, Phrynidius jonesisp. nov. from Trinitaria, and P. tuberculatussp. nov. from Jaltenango. An updated taxonomic key and illustrations of the new species are also provided.
Diversity of beetles (Coleoptera) in natural and planted saxaul forests (Haloxylon ammodendron) in the South Gobi Desert, Mongolia
Authors: Batchuluun Buyanjargal , Wunderlich Jens , Schmitt Michael
Published: December 2020

We investigated species composition and diversity parameters of beetle communities in two planted saxaul (Haloxylon ammodendron, black saxaul) forests in Southern Mongolia. We also studied nearby natural areas for comparison. Beetles were mainly collected by pitfall traps. 1064 individuals of 38 species of 22 genera in 4 beetle families were identified from planted plots. In comparison, a total of 1395 beetles belonging to 40 species of 24 genera in seven families were collected and identified from the natural saxaul plots. The most diverse beetle families were darkling beetles (Tenebrionidae, 18 species) and snout beetles (Curculionidae, 15 species) in planted and natural saxaul plots. We recorded several species (Apatophysis serricornis, Cephogenia chinensis, and Eumylada punctifera punctifera) which are associated with the saxaul tree. A darkling beetle, Anatolica potanini, was the dominant species in both natural and planted plots of the Nariin Zag forest. There were significant differences in the species richness and abundance between the planted and natural plots of the Ukhaa Zag forest. It is possible that the age of the plantation drove the differences. The higher values of diversity indices and species richness in the planted plots can be explained by the presence of rare species, represented by only one or two individuals. The planted plots and corresponding natural plots within each forest were more similar to each other in species composition and abundance than between forests.
De la souillure des rives à l’intelligence environnementale. Innover par nécessité dans les villes d’Europe du Nord
Authors: Escach Nicolas
Published: December 2020

La mer Baltique, la mer du Nord et l’océan Arctique sont trois espaces symboliques associés régulièrement à l’urgence environnementale, soit en raison d’un état déplorable de leurs écosystèmes (à l’image de la Baltique), soit en raison de menaces devenant de plus en plus pesantes sur des milieux jusqu’ici préservés (comme en Arctique). Contribuant largement à l’économie mondialisée (flux maritimes, productions énergétiques, extractions de minerais, tourisme), tout en apparaissant de plus en plus vulnérables aux conflits géopolitiques, les villes d’Europe du Nord n’ont pas considéré la souillure comme une question déterministe mais comme une ouverture possibiliste pour redéfinir leurs stratégies territoriales et interterritoriales et engager de nouvelles trajectoires. En quoi l’étude des innovations qu’elles ont instaurées peut-elle contribuer à ouvrir un nouveau regard sur l’ingéniosité territoriale et sur l’une de ses déclinaisons, l’intelligence environnementale ? Les territoires liquides, considérés comme purs ou souillés, semblent participer à toutes les échelles à l’évolution et à la recomposition des systèmes spatiaux urbains et à leurs dynamiques systémiques de transition.
Power without politics? Nature, landscape and renewable energy in Iceland
Authors: Benediktsson Karl , Waage Edda Ruth Hlín
Published: December 2020

Alors que l’accroissement des énergies renouvelables est devenu une priorité pour la plupart des pays, le développement de sites de production dédiés fait souvent l’objet de conflits d’intérêt où s’opposent impératifs d’exploitation des ressources et de protection de la nature. En Islande, la planification énergétique reflète à bien des égards l’idéologie post-politique, dont on peut suspecter qu’elle accentue les conflits plutôt qu’elle ne les règle. La part du renouvelable dans le mix énergétique primaire de l’Islande, qui jouit d’un gisement d’énergies renouvelables considérable, est supérieur à 80%. L’application de politiques néolibérales au secteur de l’énergie se traduit par une pression accentuée des compagnies privées pour développer de nouveaux sites de production, situés pour un certain nombre sur des espaces à haute valeur écologique et/ou paysagère. Le dispositif national existant d’aide à la résolution des conflits d’intérêt liés à l’aménagement du territoire n’a pas été, jusqu’ici, à la hauteur des attentes suscitées lors de sa création. Le présent article défend l’idée que l’idéologie post-politique sur lequel repose le dispositif rend en réalité l’adoption démocratique de décisions afférentes au futur développement du secteur énergétique impossible, et soutient qu’une politique agonistique est nécessaire au développement responsable du secteur de l’énergie, ce qui permettrait à l’Islande de contribuer réellement à la transition énergétique globale sans avoir à sacrifier localement les valeurs de protection de la nature.

La caste des gardiens de sécurité à Delhi : un problème géographique ?
Authors: Carrière Damien
Published: December 2020

Le maintien de la ségrégation entre riches et pauvres dans la capitale indienne est assuré par le travail quotidien et pénible de dizaines de milliers de gardiens de sécurité privée, employés par des associations de quartiers, des individus ou des commerçants. Mon travail de recherche à Delhi, effectué entre juillet 2016 et juillet 2017, a montré une surreprésentation surprenante de brahmanes parmi ces gardiens dans tous les quartiers étudiés, des brahmanes qui dominent en principe le système des castes, Cependant il ne faut pas comprendre ce dernier comme figé, ou comme une survivance du passé, mais comme une structure dynamique qui s’incarne et se fait sentir – et ressentir – à travers la société indienne. Cet article présente le cheminement parcouru pour expliquer ce phénomène. À partir du problème de la domination des plus riches sur l’espace urbain de Delhi, se découvrent un rapport au travail, au recrutement, aux migrations, ainsi qu’une double exclusion : celle des pauvres des quartiers riches d’une part, et celle des musulmans du secteur de la sécurité privée d’autre part.
Des militantes du désordre. Femmes et communistes à Tunis, 1921-1922
Authors: Abassade Élise
Published: December 2020

Des femmes s’engagent en faveur de la Fédération tunisienne de la Section française de l’Internationale communiste (SFIC), à Tunis, dès sa première année d’existence. À partir de la restitution des parcours de ces premières communistes de Tunisie, cet article interroge en quoi les archives de la police coloniale, principales sources disponibles pour documenter les premiers temps du groupe communiste, révèlent leurs faits et gestes et transcrivent les rapports sociaux en cours. Ce faisant, il examine les façons dont ces militantes investissent l’espace d’engagement politique ouvert par ce parti, prônant indépendance de la Tunisie et égalité entre toutes et tous. Si la Fédération constitue un cadre propice à leur présence, les difficultés qu’a cette organisation politique à se saisir des injonctions soviétiques à l’égard des femmes comme des faits de langage policiers mettent en exergue la transgression que représente l’engagement de ces premières militantes, ce que confirme leur trajectoire.
What is not in a name? Toponymic ambivalence, identity, and symbolic resistance in the Nepali flatlands
Authors: Karki Darshan , Wenner Miriam
Published: December 2020

This paper seeks to understand how elites utilize toponyms to either underscore territorial claims and belonging to a nation or to undermine those claims. Analyzing the names of the Nepali flatlands, Tarai and Madhes with a focus on the latter, it shows how ambivalent meanings attached to the toponyms became instrumental in symbolic resistance against an exclusionary idea of the Nepali nation and the struggle for belonging to it. Drawing on interviews with politicians, activists, political analysts, and journalists we propose to understand toponyms as temporary anchor points around which elites strategically assemble otherwise ambivalent identities to place demands in ways that are understandable to state officials. This article highlights the complexities and contradictions in place naming processes when entangled with ethnic politics and territorial restructuring.
Migrantes et engagées
Authors: Schmoll Camille
Published: December 2020

Étudier les migrations au féminin sous le prisme de l’engagement porté par les études de genre permet de sortir des représentations stéréotypées accolées aux femmes migrantes d’aujourd’hui. Ni héroïnes, ni victimes, elles sont pleinement actrices de leur migration. Leurs trajectoires migratoires diversifiées recouvrent un mouvement d’autonomisation qui se traduit à la fois, sur le plan politique, par des revendications pour la reconnaissance de leurs droits et, sur le plan personnel, par le développement de leur capacité d’action.

Longtemps ignorées par les sciences humaines et sociales, les femmes immigrées sont désormais rarement oubliées dans les recherches, même si certains points aveugles et stéréotypes perdurent. Attentive à l’articulation de la recherche scientifique et des mobilisations politiques dans le contexte français, l’analyse du chemin parcouru depuis les années 1970 révèle une succession de figures féminines de l’immigration, parfois concomitantes : les mères de famille, les femmes discriminées et les femmes engagées.
Les femmes et l’islam dans la décennie 2000
Authors: Poli Alexandra , Fabbiano Giulia
Published: December 2020

La place grandissante occupée, en France, par l’islam dans le débat public et les sciences sociales dessine de nombreuses figures des femmes dites musulmanes. L’entremêlement des dimensions du genre, de l’origine et de la religion favorise depuis longtemps une production foisonnante d’expressions et d’approches, non exemptes de clichés, pour évoquer et étudier les femmes migrantes et descendantes de parents immigrés. Une recherche, menée entre 2007 et 2010, permet d’interroger plusieurs profils de ces femmes sur leur rapport à l’islam et leur participation à la sphère civique et politique.

Une enquête qualitative en cours, dont les résultats présentés ici sont centrés sur les personnels féminins, permet d’approfondir la connaissance des liens entre parcours migratoires et professionnels au sein de l’hôpital.
La division sexuelle du travail militant dans les mobilisations antiracistes franciliennes
Authors: Picot Pauline
Published: December 2020

L’enquête ethnographique dans des associations dédiées à la lutte autonome des racisé·e·s contre le racisme permet de questionner les rapports sociaux de sexe dans le travail militant, à la fois dans la répartition des tâches et dans la définition des objectifs de ces mobilisations. L’engagement des militantes éclaire la prise en compte des discriminations croisées dans l’élaboration de leur participation politique. Dépositaires d’un fort capital culturel, ces militantes défendent leur autonomie en tant que femmes tout en affirmant leur solidarité avec les hommes, fondée sur une expérience commune du racisme.

Este artigo trata-se da elaboração de materiais didáticos para promover a inclusão de deficientes visuais em sala de aula. Pois, como tais alunos estão presente em escolas de ensino regular, é necessário que os educadores procurem formas de incentivar os alunos a participar e interagir na realização de tarefas escolares, através da organização de atividades específicas às necessidades  diversas dos alunos, para que assim, a  criança com deficiência visual possa expor suas ideias. Dessa forma a realização de atividades lúdicas oportunizam a interação entre alunos, a autonomia, ​criticidade, a exposição de ideias e a brincadeira, incluindo então, o deficiente visual no processo de ensino e aprendizagem.  As crianças com deficiência visual precisam explorar suas possibilidades através da liberdade para manusear, tocar e receber conceitos concretos e abstratos do mundo que os cercam para que possam usar estes conhecimentos na escola e outros ambientes. Por isso, crianças com deficiência visual podem e devem ser incluídas nas atividades, observando adaptações eventuais. O objetivo principal deste trabalho é apresentar uma estratégia para abordar temas de Astronomia com crianças e adolescentes de baixa visão ou cegos promovendo de fato a inclusão. Uma das estratégias apresentadas é uma adaptação de um Jogo da memória para facilitar a inclusão dos deficientes visuais no estudo das constelação, como também uma maquete tátil-visual que pode ser utilizada para ensinar tanto as estações do ano como a ocorrência do dia e a noite.

No cenário contemporâneo ainda convivemos com desigualdades e preconceitos de gênero, seja no mercado de trabalho, nas universidades ou em carreiras científicas. Esse cenário é reflexo de uma cultura patriarcal e machista que naturaliza as diferenças e desigualdades. No campo das Ciências Exatas e Engenharias não é diferente. Estatísticas e estudos mostram que as mulheres são minoria em cursos de graduação ou pós-graduação na área. Também revelam que há um forte desestímulo social e escolar para que meninas escolham essa área. A Chamada 031/2018 do CNPq surge como uma iniciativa pública de fomento para contribuir na reversão dessas estatísticas. O objetivo deste artigo é apresentar as principais ações da proposta Meninas na Ciência da Universidade do Vale do Taquari – Univates, problematizando questões de gênero na área das Ciências Exatas e Engenharias. A natureza coletiva deste projeto se reflete também na estrutura deste artigo, que representa vozes, inquietações e iniciativas de muitas meninas e mulheres. As seções dois e três resultam do trabalho de três bolsistas de iniciação científica júnior (ICJ) do CNPq e de bolsista de extensão de projeto vinculado ao Programa de Extensão Ciências Exatas e Engenharias.
A ASTRONOMIA E OS LIVROS DIDÁTICOS DE CIÊNCIAS: UMA COMPARAÇÃO ENTRE O PNLD 2017 E O PNLD 2020
Authors: Buffon Alessandra Daniela
Published: December 2020

Este artigo tem como objetivo analisar a presença da Astronomia nos livros didáticos de Ciências aprovados no PNLD 2020 em comparação com os aprovados no PNLD 2017. A pesquisa é de natureza qualitativa, seguindo os pressupostos metodológicos da pesquisa qualitativa descritiva, tendo como objeto de pesquisa os livros didáticos de Ciências aprovados pelo PNLD 2017 e pelo PNLD 2020. Como resultado, observa-se que, de modo geral, existe uma maior frequência da Astronomia nas coleções atuais em comparação com a anterior. Apesar de ser observado um progresso nas coleções que se mantiveram nas duas avaliações é preciso que área tenha um olhar crítico em como esses conteúdos estão sendo abordados nos materiais. Por fim, salienta-se que a ampliação da Astronomia nos livros didáticos não garante a ampliação dessa discussão em sala de aula, apenas pode otimizar o tempo de busca dos professores e alunos pela temática e fomentar a sua importância no currículo escolar.
ANÁLISE DOS PRODUTOS EDUCACIONAIS PROVENIENTES DO MESTRADO NACIONAL PROFISSIONAL EM ENSINO DE FÍSICA
Authors: Zara Reginaldo A. , Casanova Samuel S.
Published: December 2020

A produção de material didático para ensino de Física tem sido impulsionada pelos Programas de Mestrado na modalidade profissional pois, além da dissertação, os mestrandos devem produzir um Produto Educacional (PE) e implementá-lo em sala da aula. No caso do Mestrado Nacional Profissional em Ensino de Física, entre os anos de 2013 (ano de implantação) e 2018 foram disponibilizados mais de 300 Produtos Educacionais diferentes no site no Programa na Internet. Neste trabalho apresentamos proposta de análise e classificação dos Produtos Educacionais provenientes do MNPEF, partindo de suas caraterísticas fundamentais como a Subárea predominante, Temática Principal, Natureza e Tipologia. Este tipo de análise ainda não está presente na literatura apesar da quantidade relevante de PE produzidos até o momento. Com isso, esperamos construir uma classificação dos Produtos Educacionais com base em seu conjunto de caraterísticas que possa servir de guia aos professores para a escolha de PE a serem utilizados em sala de aula.

Published: December 2020

Neste trabalho é relatado uma experiência didática para o ensino de Física, realizada numa oficina inter-seriada do Ensino Médio no Colégio SESI de Francisco Beltrão-PR. Na ocasião, o objeto de conhecimento trabalhado foi o estudo da energia e suas transformações. A estratégia utilizada para este trabalho foi a aplicação de metodologias ativas de ensino como alternativa ao ensino tradicional nas salas de aula. Essas metodologias consistem na sala de aula invertida e no PIE (Predizer, Interagir, Explicar). Os pressupostos teóricos utilizados para o processo de ensino e aprendizagem consistiu em David Ausubel (aprendizagem significativa) e a instrução por pares (PeerInstruction). Após uma breve descrição do que consiste as metodologias ativas utilizadas e dos pressupostos teóricos, se dá o relato dos autores na aplicação em sala de aula. Os resultados mostram como se deu o envolvimento dos alunos, que foram os protagonistas durante este processo de ensino e aprendizagem. Espera-se que este trabalho possa ser útil ao apresentar alternativas metodológicos para o ensino de Física.

Published: December 2020

Our previous study documented that melatonin (MLT) induced the osteogenic differentiation of mesenchymal stem cells (MSCs) and promoted the healing of femoral fractures in rats via the neuropeptide Y (NPY)/neuropeptide Y1 receptor (NPY1R) signaling pathway. MLT treatment upregulated the expression of the zinc uptake transporter zinc transporter 1 (Zip1) in nerve cells. Prior research demonstrated that oral zinc upregulated NPY expression. MSCs were isolated from rat bone marrow and identified using flow cytometry in our study. The results showed that MLT treatment upregulated NPY and NPY1R levels in MSCs with osteogenic differentiation, which was accompanied by upregulated Zip1 expression. However, the MLT-induced osteogenic differentiation of MSCs was reversed after interference of Zip1 expression. It was confirmed by the decreased alkaline phosphatase (ALP) level; downregulated activities of type I collagen α1 chain (COL1A1), osteocalcin (OCN), runt-related transcription factor 2 (Runx2) and ALP; and reduced mineralized nodule formation. MLT promoted fracture healing in rats with femoral fracture, which was accompanied by increased expression of NPY and NPY1R and significantly increased expression of Zip1. In contrast, the silencing of Zip1 expression reversed MLT-mediated fracture healing. In summary, Zip1 participated in the regulation of the NPY/NPY1R signaling pathway via MLT to promote the osteogenic differentiation of MSCs and fracture healing.

The aim of the present study was to evaluate the occurrence of Salmonella spp., Verotoxigenic E. Coli (VTEC) and enumerate E. coli in shellfish (Mytilus galloprovincialis and Ruditapes decussatus) collected before and after depuration from two class B harvesting areas located in Sardinia (Italy). All the samples were analyzed for Salmonella spp. detection according to European Commission Regulation (EC) 2073/2005 and examined using the five tube Most-Probable-Number (MPN) method for enumeration of E. coli in accordance with the European Union reference method ISO 16649-3:2015. E. coli VTEC was investigated following a direct multiplex Polymerase Chain Reaction (PCR) screening test. The enumeration of E. coli met the European law limit for Class A areas of 230 MPN/100g. The averaged enumeration of E. coli in samples of M. galloprovincialis and R. decussatus collected at the harvesting time was 39 and 37 MPN/100 g respectively. The average contamination levels in samples collected after purification were 58 MPN/100g (M. galloprovincialis) and 32 MPN/100 g (R. decussatus). E. coli VTEC was not detected, on the contrary, Salmonella ser. Typhimurium was detected in one sample of M. galloprovincialis and in one sample of R. decussatus collected at the harvesting time. No significant associations were observed between E. coli levels in shellfish and environmental parameters of water or with the detection of Salmonella ser. Typhimurium in M. galloprovincialis and R. decussatus samples. Nevertheless, the occurrence of Salmonella ser. Typhimurium, involved in human infection outbreaks, should be considered a potential risk for consumers.

Published: December 2020

Objectives:

The objective of the study was to determine the risk of subsequent keratitis in prostate cancer (PCa) patients treated with androgen deprivation therapy (ADT).

Materials and Methods:

Three thousand three hundred and nine patients with PCa were identified using data from Taiwan’s National Health Insurance Research Database for 2001 through 2013. Among those patients, 856 treated with ADT comprised the study group, while 856 non-ADT-treated patients matched with 1:1 propensity-score-matched analysis comprised the control group. The demographic characteristics and comorbidities of all the patients were analyzed, and Cox proportional hazards regression was utilized to determine the hazard ratios (HRs) for subsequent keratitis.

Results:

A total of 157 (9.2%) patients had newly diagnosed keratitis. Compared to the non-ADT-treated patients, the ADT-treated patients had a reduced risk of subsequent keratitis, with an adjusted HR of 0.38 (95% confidence interval: 0.27–0.55; P < 0.001).

Conclusion:

ADT treatment apparently decreased the risk of subsequent keratitis in the investigated PCa patients, but the clinical significance of this finding should be further assessed in additional studies.
On polynomially integrable Birkhoff billiards on surfaces of constant curvature
Authors: Glutsyuk Alexey
Published: December 2020

The polynomial version of the Birkhoff Conjecture on integrable billiards on complete simply connected surfaces of constant curvature (plane, sphere, hyperbolic plane) was first stated, studied and solved in a particular case by Sergei Bolotin in 1990–1992. Here we present a complete solution of the polynomial version of the Birkhoff Conjecture. Namely, we show that

every polynomially integrable real bounded planar billiard with

C^2

-smooth connected boundary is an ellipse

. We extend this result to billiards with piecewise smooth and not necessarily convex boundary on an arbitrary two-dimensional simply connected complete surface of constant curvature: plane, sphere, Lobachevsky–Poincaré (hyperbolic) plane; each of them being modeled as a plane or a (pseudo-) sphere in

\mathbb R^3

equipped with an appropriate quadratic form. Namely, we show that
a billiard is polynomially integrable if and only if its boundary is a union of confocal conical arcs and appropriate geodesic segments
. We also present a complexification of these results. These are joint results of Mikhail Bialy, Andrey Mironov and the author. The proof is split into two parts. The first part is given in two papers by Bialy and Mironov (in Euclidean and non-Euclidean cases respectively). Their geometric construction reduced the Polynomial Birkhoff Conjecture to a purely algebro-geometric problem to show that an irreducible algebraic curve in

\mathbb {CP}^2

with certain properties is a conic. They have shown that its singular and inflection points lie in the complex light conic of the above-mentioned quadratic form. In the present paper we solve the above algebro-geometric problem completely.
On discrete loop signatures and Markov loops topology
Authors: Le Jan Yves
Published: December 2020

Our purpose is to explore, in the context of loop ensembles on finite graphs, the relations between combinatorial group theory, the topology of loops, loop measures, and signatures of discrete paths. We determine the distributions of the loop homotopy class, and of the first and second homologies, defined by the lower central series of the fundamental group.
