Authors: Kokhanovska Olena , Dovgij Oleg
Published: March 2023

For students to successfully master mathematics in the conditions of a digital educational environment, it is important to create conditions that would promote an increase in the interest in learning of students of primary education and ensure the development of their abilities and key competencies in the learning process. The article examines the essence, content and forms of educational cooperation in remote mathematics lessons in elementary school with the help of digital applications. It is emphasized the need to use digital technologies both in the process of developing digital literacy of teachers and in the context of organizing digital cooperation between teachers and younger students in the context of using ICT tools and creating conditions for their integration into the educational process. The requirements of the Concept of the New Ukrainian School regarding the mathematical competence of lower grade students were considered. The essence of the key concepts of the research is analyzed. The principles of cooperative learning are highlighted. It was noted that the main idea of cooperative learning is to learn together, and not just to perform together. The technology of preparing and conducting a mathematics lesson using the remote form of learning in cooperation based on small groups is described. Some forms of organizing collaborative learning in remote mathematics lessons based on small groups and digital means of their implementation are outlined. Special mathematical websites and applications are presented that can significantly motivate students to solve mathematical problems, visualize content and develop key competencies of students. It was concluded that the organization of educational cooperation in a digital educational environment in mathematics lessons in elementary school involves such interaction between the teacher and students, students among themselves in the educational situation, during which the children's established methods of action are restructured, the components of educational activity are formed (that is, formed learning ability).

Authors: Marchii-Dmytrash Tamara , Kyrsta Nataliia , Matishak Marianna
Published: March 2023

The article focuses on the fact that in the process of professional training, it is necessary to ensure the proper level of forming of the communicative culture of future educators of institutions of preschool education (IPE), and also substantiates its psychological and pedagogical foundations in the context of an interdisciplinary approach. Various approaches to the interpretation of the concepts "culture of communication", "communication ethics", "communicative culture", "communicative competence" have been analyzed. In order to form the communicative culture of future teachers of IPE, it is important to implement a humanistic paradigm of education, which involves partnership interaction of participants in the educational process, student-centeredness in the broad sense, a variety of activities of education seekers, a personally oriented style of communication, interaction and benevolent demandingness. An interdisciplinary approach in the context of the researched problem ensures systematicity, integrity and integration of scientific knowledge for the effective forming of the communicative culture of future educators. The psychological foundations of the specified process during the study of the disciplines of the psychological-pedagogical cycle and the teaching methods of individual disciplines, taking into account the interdisciplinary approach, are determined, in particular, the enrichment of the content of educational components with relevant scientific knowledge about the essence of the concepts of "communication", "communicative culture", the study of age and individual-psychological features of communication with preschool age children, their parents and other persons of the educational process in the IPE, assimilation of rules and ethical norms of communication; the usage of interactive forms and methods of learning during mastering the program content of the disciplines; interaction of participants in the educational process on the basis of partner pedagogics. The main idea of the article is that the culture of speech is actively formed in preschool age children (phonetically and orthographically correct and clean pronunciation of sounds, words and phrases, mastering the cultural norm of language, etc.), accordingly, it is important that the teacher of IPE was a role model and perfectly possessed communicative culture.

Keywords: communicative culture, communication, future educator, institution of preschool education (IPE), professional training, interdisciplinary approach, institution of higher education, educational component, educational process.

Authors: Svoboda Tomáš , Sikora Adam , Záborský Vladimír , Gaffová Zuzana
Published: March 2023

Knowledge of the force required to overcome deformation at the proportionality limit, yield point, as well as knowledge of the effect of selected factors on the characteristics during bending stress, have scientific and practical significance. They are the basis for designing tools for bending and accurately determining the stresses to which products and their parts may be subjected during use. This study analyzed the effect of selected factors on the selected characteristics, including the forces at the proportionality limit (FE) and yield point (FP). The chosen factors of this study were the wood species (Fagus sylvatica L. and Populus tremula L.), non-wood component (carbon and fiberglass), non-wood component position in the composition matrix (up and down), material thickness (6 mm, 10 mm, and 18 mm), and adhesive used (polyvinyl acetate and polyurethane), as well as their combined interaction. The results contributed to the advancement of knowledge necessary for the study and development of new materials with specific properties for their intended use. The results could improve the innovative potential of wood processing companies and increase their performance and competitiveness in the market.
Modern works by Kuban composers on the orthodox canonical liturgical texts
Authors: Khvatova Svetlana , Shak Tatiana
Published: March 2023

The article is devoted to the compositions of Kuban composers of the 21st century on Orthodox canonical liturgical texts. The features of the musical poetics of the works, their stylistic prototypes, as well as the motivation for turning to spiritual topics are considered. The problem of rapprochement of two lines of choral performance - church and secular is touched upon. Attention is drawn to the precedent of inlaying canonical liturgical texts as a private means of artistic expression in the context of a secular composition. Attention is focused on a careful renewal of the means of musical expressiveness of compositions, taking into account the traditional author's poetics of liturgical chants. The signs of following the style model of Obikhod in the harmonization of S. Smolensky, as well as the compositional techniques of the authors of the New Direction in Russian sacred music at the turn of the 19th-20th centuries, are revealed. The importance of the composer's church singing experience for the adequate embodiment of the verbal basis of rites in chanting is emphasized. A causal relationship is revealed in the change in the musical interpretation of the liturgical verbal basis in secular compositions under the influence of the concept of the opus, where the canonical liturgical text is “encrusted”. It also shows the dependence of the expansion of liturgical chants on the concert stage and secular compositions on the kliros on the processes of personnel “migration” of singers, the role of the individual in the development of this type of art, and the concept of the development of a creative team.
Images of elephants in the book "Symbols and emblemata" (1705)
Authors: Zvezdina Yuliya
Published: March 2023

The article examines images of elephants, reproduced several times on various emblems from the book "Symbols and Emblemata", published in 1705 in Amsterdam by decree of Tsar Peter I. The author compares the details of the emblematic engravings, compares them with the accompanying inscriptions. The image of the first emblem from the book of 1705 and the engravings from its main source – the edition of the emblems of Daniel De La Fey of 1691 is also compared. The quality of the two editions is compared. Attention is paid to the images of the elephant and the semantic interpretation of this image in the Old Russian tradition, primarily in the "Physiolog", in comparison with the transformation of the image in Peter's time. Icons and miniatures containing the image of this animal are mentioned. The symbolic likenesses of the elephant found in the Old Russian tradition and taken from the translation of the Greek “Physiolog” are particularly noted. The earliest monument is marked - the relief of St. George's Cathedral in Yuriev Polsky. There is also a later monument of the century – the painted gates of the middle of the XVIII century from the Rostov Kremlin, which have not survived to the present day and are known from photographs of the 1910s by S.M. Prokudin-Gorsky. The images of elephants (as well as other images) on them are taken from the book of 1705.
Alexander Nevsky cathedral in Tallinn as a monument of Russian style in Estonia
Authors: Bertash Alexander
Published: March 2023

The article is devoted to the most significant church building in the Baltics at the end of the 19th century - Cathedral of St. Blessed Prince Alexander Nevsky in Revel (Tallinn). The semantics of the dedication of the temple and its architectural and construction history are considered in the context of church architecture of the Russian Empire in the late 19th — early 20th century and the political course of Emperor Alexander III, known as Russification. The initiator of the construction of a declaratively Russian imperial structure in the center of Revel Vyshgorod (Toompea) with its predominant medieval German architecture was the Estonian governor, Prince S.V.Shakhovskoy, through whose zeal the construction acquired all-Russian significance. The cathedral is one of the most striking works of the Moscow-Yaroslavl version of the Russian style within the boundaries of the former Russian Empire and the most important in the work of the outstanding master of this style, architect M.T. Preobrazhensky. The cathedral, which has never been devastated, despite attempts to close and rebuild it in the 1920s-1940s, still preserves unique Russian-style interiors in terms of safety and integrity. They allow us to present the style of works known in the early twentieth century masters: A.N.Novoskoltsev, Abrosimovs; most of their other works were destroyed during the anti-church persecution in the USSR. The topic of the article is related to the author's previous publications about the architecture of the Puhtitsa Holy Dormition Monastery and Orthodox church building in Estonia.
Causal Knowledge Modelling for Agile Development of Enterprise Application Systems
Authors: Noreika Karolis , Gudas Saulius
Published: March 2023

Experience shows that Agile project management tools such as Atlassian Jira capture the state of EAS projects by relying solely on expert judgement that is not supported by any knowledge model. Therefore, the assessment of project content against strategic objectives and business domain features are not supported by any tool. This is one of the reasons why Agile project management still does not provide sufficient EAS project delivery results. In order to address this problem, the Enterprise Application Software (EAS) development using Agile project management is summarized in a conceptual model. The model highlights the knowledge used and indicates its nature (empirical or causal digitized). The modified Agile management process we have developed and described in previous works is based on causal knowledge models that supports EAS development and Agile management processes. The purpose of this article is to specify knowledge repository to ensure the Agile management solutions of an EAS project are aligned with strategic goals and business domain causality. It is worth noticing that strategic goals have been identified and specified as capabilities using some enterprise architecture framework (NAF, MODAF, ArchiMate, etc.). The novelty of the proposed method is incorporating the business domain causal knowledge modelling approach into the Agile project management process. The causal knowledge unit is considered as a Management Transaction (MT), which includes closed loop dependence of its components. The modified Agile activity hierarchy (theme, initiative, epic, user story) defines the required content of their mutual interactions. An important new results obtained are the conceptual model of causal knowledge base (KB) and specification of enhanced Agile management tool components: project management database and project state assesment knowledge base. Causal KB includes specification of causal knowledge unit (MT metamodel) and specifications of traditional and causal Agile hierarchy meta-models. These conceptual models define the causal knowledge components necessary to evaluate the state of Agile activities in the EAS development project using intelligent Agile project management tool.

BACKGROUND AND OBJECTIVES

Representative enrollment of racial and ethnic minoritized populations in biomedical research ensures the generalizability of results and equitable access to novel therapies. Previous studies on pediatric clinical trial diversity are limited to subsets of journals or disciplines. We aimed to evaluate race and ethnicity reporting and representation in all US pediatric clinical trials on ClinicalTrials.gov.

METHODS

We performed a cross-sectional study of US-based clinical trials registered on ClinicalTrials.gov that enrolled participants aged <18 years old between October 2007 and March 2020. We used descriptive statistics, compound annual growth rates, and multivariable logistic regression for data analysis. Estimates of US population statistics and disease burden were calculated with the US Census, Kids’ Inpatient Database, and National Survey of Children’s Health.

RESULTS

Among 1183 trials encompassing 405 376 participants, race and ethnicity reporting significantly increased from 27% in 2007 to 87% in 2018 (P < .001). The median proportional enrollment of Asian American children was 0.6% (interquartile range [IQR], 0%–3.7%); American Indian, 0% (IQR, 0%–0%); Black, 12% (IQR, 2.9%–28.4%); Hispanic, 7.1% (IQR, 0%–18.6%); and white 66.4% (IQR, 41.5%–81.6%). Asian American, Black, and Hispanic participants were underrepresented relative to US population demographics. Compared with expected proportions based on disease prevalence and hospitalizations, Asian American and Hispanic participants were most consistently underrepresented across diagnoses.

CONCLUSIONS

While race and ethnicity reporting in pediatric clinical trials has improved, the representative enrollment of minoritized participants remains an ongoing challenge. Evidence-based and policy solutions are needed to address these disparities to advance biomedical innovation for all children.
Calidad del empleo y estructura del mercado de trabajo en América Latina desde una perspectiva comparada
Authors: Fernández-Franco Sebastián , Graña Juan , Lastra Facundo Martín , Weksler Guido
Published: March 2023

Los aportes latinoamericanos a las teorías del mercado laboral destacan que la región se caracteriza por la existencia de una importante heterogeneidad productiva, que se expresa en la convivencia de unidades de muy variada productividad y calidad del empleo.

En este marco, este trabajo tiene dos objetivos. Primero, analizar la situación actual de los mercados de trabajo de América Latina de manera comparada. Para ello se estudia la calidad del empleo e ingresos de asalariados y no asalariados en 13 países latinoamericanos, trabajando con 9 perfiles ocupacionales construidos según calificación del puesto de trabajo y tamaño del establecimiento.

En segundo lugar, evaluar cuál es el nivel de deterioro del poder adquisitivo de los salarios de la región y su heterogeneidad entre perfiles. Para ello, se comparan los ingresos de éstos respecto a Estados Unidos, representante de los países desarrollados.

Los resultados confirman que los aportes de la literatura siguen vigentes y que los niveles salariales y de calidad del empleo promedio se encuentran marcadamente por debajo de los de Estados Unidos. Se concluye que el rezago productivo que caracteriza a la región se traduce en un deterioro general de las condiciones laborales, que se expresa con mayor fuerza en los pequeños establecimientos.
Global Inequality in the Current Era
Authors: Nudelsman Susana
Published: March 2023

One of the most vehement criticisms to the current global era refers to the issue of huge income disparities within and between countries. At present, global inequality is higher than it was 200 years ago but, at the same time, up to COVID 19, the Gini index marks the first time since the Industrial Revolution that it stopped rising. This downward trajectory has been driven by a decline in between-country inequality —the main explanatory factor for global income disparities— partially offset by a rise in within-country inequality. The downward trend between countries should not be unexpected, since low-income countries in Asia, particularly China, have experienced growth rates substantially above the world average in the context of a rapid industrialization process. The pandemic has revealed and worsened preexisting inequalities in both within and between countries, so that global inequality also appears to have increased since its outbreak.
Tulathromycin – a semi-synthetic macrolidе antibiotic. I. Characteristics and antibacterial activity
Authors: Mladenov D. , Yordanov S. , Dimitrova A.
Published: March 2023

This article reviews the available literature on the characteristics and antimicrobial activity of the semi-synthetic macrolide antibiotic tulathromycin from the triamilides subclass. The product has a high activity against Gram-negative respiratory pathogens and desirable pharmacological characteristics for high and persistent tissue levels in domestic animals. Representatives of the macrolide and lincosamide group are investigated and the similarities and differences from tulathromycin are outlined. It is emphasised that at the background of increasing bacterial resistance to a number of antimicrobial agents, only few tulathromycin-resistant strains of P. multocida and M. haemolytica have been reported so far. Tulathromycin is considered highly effective against common bacterial agents of respiratory diseases in large ruminants, pigs and sheeps, and may be an alternative for control of resistant bacterial pathogens

Published: March 2023

This study aims to select the suitable density of the material according to the mechanical properties needed by the 3D-printing application in which it will be used. 3D-printed carbon fiber filaments with different printing densities have been tensile, and a fatigue test was experimented with to find the mechanical properties. Furthermore, the modulus of elasticity, yield stress, and ultimate tensile strength of the material was determined by analyzing the stress-strain curves. The result shows that the parts printed with a high infill density give better mechanical properties, more time to build the object, more strength, and heavier weight than those printed with low infill density.

Published: March 2023

A escola é um ambiente de interação e aprendizado que está em constante transformação. Atualmente, fenômenos sociais, como o uso das novas tecnologias da educação e a inclusão do aluno com deficiência na sala de aula comum do ensino regular, estão cada vez mais presentes na escola. A presente pesquisa objetivou investigar as crenças de professores a partir do relato dos docentes sobre o uso de tecnologias em sala de aula comum do ensino regular nas escolas inclusivas. A amostra foi composta por 45 professores de 11 escolas da rede municipal de ensino fundamental. Os dados foram coletados por meio de questionário e entrevista individual e analisados utilizando-se o software Iramuteq. O software gerou dois eixos temáticos, subdivididos em quatro classes. Cada classe foi analisada separadamente. O estudo revelou que, para os professores, ainda são muitos os desafios na atuação com a educação inclusiva e com o uso das tecnologias. Verificou-se que os professores possuem crenças de que a educação inclusiva é importante e que o uso das tecnologias poderia favorecer o processo educativo dos alunos com deficiência. Foram identificados como crenças potencialmente facilitadoras em relação ao uso das tecnologias na educação inclusiva aspectos como: necessidade de melhora na estrutura da escola, mais recursos, formação básica e continuada e apoio do governo, tanto no que se refere à possibilidade de o professor ter acesso pessoal às tecnologias quanto à sua formação para lidar com a educação inclusiva e com as tecnologias da informação e comunicação.

Published: March 2023

Abstract The objective was to evaluate the residual action of the insecticides acetamiprid + etofenprox, spinetoram, indoxacarb and methoxyfenozide on the predator Chrysoperla externa Hagen, 1861 (Neuroptera: Chrysopidae). The bioassays followed the methodologies proposed by the International Organization for Biological and Integrated Control (IOBC). The insecticides were sprayed on grapevine plants cv. Burgundy, using the maximum recommended field dosage for fruit trees. Larvae and adults of the predator were exposed to leaves containing the insecticide residues, at 3, 10, 17, 24 and 31 days after spraying, to determine the residual effect on the following biological parameters: mortality, fecundity and fertility. Based on the toxicity observed during the bioassays, the insecticides were classified according to the IOBC persistence scale. Spinetoram was classified as moderately persistent to larvae and slightly persistent to adults, indoxacarb also he was consideredpersistent for larvae and as a short-lived for the adult stage of the lacewing, thus showing the difference in susceptibility between the stages of development of C. externa. The insecticides acetamiprid + etofenprox and methoxyfenozide are the most suitable for ecologically safe application, in areas where the predator occurs because they are classified as short-lived insecticides for the larval and adult stages of C. externa.

Published: March 2023

Resumo O adenocarcinoma ductal de pâncreas é uma das neoplasias malignas mais agressivas, com taxas de sobrevivência anuais inferiores a 20%. Os métodos axiais (tomografia computadorizada e ressonância magnética) têm papel fundamental no diagnóstico e estadiamento da doença, por fornecerem adequada resolução anatômica na avaliação de estruturas-chave, principalmente vasculares. O adenocarcinoma ductal de pâncreas é frequentemente descoberto em estágios avançados e sem viabilidade de ressecção cirúrgica, e nesse cenário o desenvolvimento de alternativas terapêuticas minimamente invasivas tem sido ainda mais importante para a mudança de sua história natural. A eletroporação irreversível, procedimento intervencionista que minimiza efeitos deletérios nos tecidos adjacentes, vem se destacando no tratamento de lesões tradicionalmente consideradas irressecáveis. Essa técnica, apesar de ganhar cada vez mais espaço no manejo terapêutico do adenocarcinoma ductal de pâncreas, ainda é pouco familiar aos radiologistas. Neste estudo, buscamos expor, de forma sucinta e didática, os fundamentos da técnica, as principais características de imagem e os critérios de elegibilidade que devem ser considerados para indicação da eletroporação irreversível nessa doença.

Abstract Objective: To evaluate the diagnostic performance of computed tomography (CT) fluoroscopy-guided percutaneous transthoracic needle biopsy (PTNB) in pulmonary nodules ≤ 10 mm during the coronavirus disease 2019 pandemic. Materials and Methods: Between January 1, 2020 and April 30, 2022, a total of 359 CT fluoroscopy-guided PTNBs were performed at an interventional radiology center. Lung lesions measured between 2 mm and 108 mm. Of the 359 PTNBs, 27 (7.5%) were performed with an 18G core needle on nodules ≤ 10 mm in diameter. Results: Among the 27 biopsies performed on nodules ≤ 10 mm, the lesions measured < 5 mm in four and 5-10 mm in 23. The sensitivity and overall diagnostic accuracy of PTNB were 100% and 92.3%, respectively. The mean dose of ionizing radiation during PTNB was 581.33 mGy*cm (range, 303-1,129 mGy*cm), and the mean biopsy procedure time was 6.6 min (range, 2-12 min). There were no major postprocedural complications. Conclusion: CT fluoroscopy-guided PTNB appears to provide a high diagnostic yield with low complication rates.

Published: March 2023

As internações de longa duração de crianças e adolescentes com condições crônicas complexas de saúde implicam em inúmeras restrições às experiências comuns da infância. Muitos deles nascem, crescem e até morrem no hospital, sem nunca terem conhecido seus lares. A experiência de cuidado deste grupo foi acionada por meio de uma investigação narrativa. Convidamos trabalhadores de um hospital pediátrico público dedicado ao atendimento de perfil clínico complexo para que contassem histórias que marcaram sua memória. A evocação da dimensão afetiva do cuidado apontou para o tensionamento dos limites normativos instituídos. A flexibilização das regras do hospital era feita em nome de um benefício para a criança ou o adolescente. Analisamos estas situações, que aqui denominamos como transgressões e concessões, para discutir aspectos importantes das microrrelações e cultura nas cenas de cuidado. Sobressaem-se mecanismos de resistência, em um esforço para suplantar ou reparar um ambiente muitas vezes identificado como desumanizador.
A soberania do visível: como a memória traumática se torna estresse traumático
Authors: Ferreira Ramon Reis dos Santos , Ortega Francisco
Published: March 2023

Desde o lançamento da terceira versão do Manual Diagnóstico e Estatístico de Transtornos Mentais (DSM-III), a psiquiatria biológica vem sistematicamente aplicando seu raciocínio classificatório a fenômenos sociais de múltiplas naturezas. Nessa perspectiva, ganha relevância o discurso do trauma, pelo qual acontecimentos de magnitude devastadora passaram a receber interpretações neurocomportamentais e foram, finalmente, reconhecidos menos por seus impactos culturais e subjetivos que pelas alterações fisiológicas que propiciam. Apoiado em revisão narrativa, este artigo procurará explorar a transição da racionalidade traumática entre o século XIX, quando o trauma fora concebido em associação ao conceito cognitivo de memória, e o século XX, quando finalmente esse fenômeno foi anexado à pesquisa neurocientífica do estresse. A pluralidade de modelos conceituais e paradigmas determinísticos pode contribuir para que a pesquisa do trauma produza protocolos de enfrentamento multifatoriais mais adequados à experiência humana do sofrimento pós-traumático.
Standard twist and non-twist maps

Published: March 2023

Symplectic maps can provide a straightforward and accurate way to visualize and quantify the dynamics of conservative systems with two degrees of freedom. These maps can be easily iterated from the simplest computers to obtain trajectories with great accuracy. Their usage arises in many fields, including celeste mechanics, plasma physics, chemistry, and so on. In this paper we introduce two examples of symplectic maps, the standard map and the standard non-twist map, exploring the phase space transformation as their control parameters are varied. Furthermore, for the non-twist map, we also present, that its chaotic motion is separated in phase space by the non-twist transport barrier.
Militância enquanto Convite ao Diálogo: o Caso da Militância Monodissidente
Authors: Vas Dani , Silva Guimarães Danilo
Published: March 2023

Resumo Este artigo é uma produção teórica de caráter reflexivo que focaliza a relação entre pesquisa e militância a partir do construtivismo semiótico-cultural em psicologia, tendo como base o caso da militância monodissidente. A noção de monodissidência foi cunhada no percurso da militância bissexual para se referir a uma ferramenta analítica de ordem político-comunitária que contempla todas as pessoas que se atraem sexual e/ou romanticamente por mais de um gênero. São contrapostas concepções distintas de militância político-social em psicologia: de um lado, militância é entendida a partir de um autocentramento do militante, vinculado a uma rede de exclusões, negações, vedação e defesas psicológicas em relação à experiência; de outro, há uma compreensão dialógica de militância. Metodologicamente, a proposta de pesquisa se fundamenta no campo da participação observante, entendendo que o pesquisador está, primeiro, na condição de participante de certo campo sociocultural, a partir do qual passa a observar e refletir sobre fenômenos que ocorrem nele. Tomamos como ilustração a trajetória de construção da militância monodissidente do primeiro autor, trazendo tensionamentos dialógicos para a análise, postos em discussão com outras reflexões situadas sobre o tema.

ABSTRACT Growing lettuce under high temperatures and light incidence, as in the Alagoas State hinterland, Brazil, induces early tasseling and decreases the quality of the product. Thus, the objective of this work was to evaluate the production and post-harvest quality of lettuce cultivars in different crop seasons in western Alagoas, Brazil. A randomized block experimental design was used, with four replications. The treatments consisted of lettuce cultivars: Baba-de-Verão, Cinderela, Elba, Mônica, Solaris, and Veneranda. The winter crop was more favorable for plant diameter, except for Baba-de-Verão, whose performance was similar in both seasons and stood out in the summer. The winter crop resulted in better performance in plant height, stem diameter, and fresh matter yield, whereas summer plants reached larger number of leaves. The cultivar Mônica presented longer stem length, denoting lower tolerance to early tasseling and, therefore, it is not indicated to be grown in the region. The cultivar Baba-de-Verão (Lisa group) reached higher fresh matter yield, number of leaves per plant, and stem diameter, and it was the most adequate cultivar to be grown in western Alagoas. Elba, Solaris, and Veneranda were the lettuce cultivars from the Crespa group that stood out. Baba-de-Verão was the cultivar that presented the best performance for chlorophyll a, b, and total. The cultivar Solaris presented the highest carotenoid contents. Plants grown in the winter reached higher chlorophyll a and total, carotenoid contents, pH, and soluble solid (SS) to titratable acidity (TA) ratio, whereas the lettuce grown in the summer had higher SS and TA.

ABSTRACT Ecosystems with dry soils are particularly sensitive to climate changes and anthropogenic actions, which represents a threat to the survival of many cactus species. Ex situ seed conservation strategies should be adopted to support in situ conservation. This study evaluated the effect of conservation conditions on germination and vigor of seeds of Pilosocereus pachycladus subsp. pernambucoensis and Tacinga inamoena. The seeds were packaged in paper bags and glass containers and stored under controlled (8 ± 1 °C; 56 ± 2% relative humidity) and non-controlled (24 ± 2 °C; 75 ± 5% relative humidity) environmental conditions for 0 (control), 12, 16, and 20 months. The experiment was conducted in a completely randomized design, in a 2 × 2 × 4 factorial arrangement (conservation environment × packaging × storage period) for each species. The variables evaluated were: water content (%), germination (%), germination speed index (GSI), and mean germination time (MGT). The physiological quality of seeds of both species were preserved when seeds were maintained under controlled environment, regardless of the packaging. However, when stored under non-controlled environment, the packaging in paper bags was more efficient for the conservation of seeds of P. pachycladus subsp. pernambucoensis, and the glass container was more efficient for T. inamoena. This information may be needed for ex situ conservation of these species and to support the recovery of degraded areas susceptible to desertification in the Caatinga biome.
Acciones Performáticas, Derechas y Mediatización: el caso de Jóvenes Republicanos (Argentina)
Authors: Camezzana Daniela , Capasso Verónica
Published: March 2023

RESUMEN Este artículo trata de dos performances realizadas en 2021 por la agrupación política argentina de derecha Jóvenes Republicanos (JR) y su retoma mediática. La hipótesis es que JR adopta elementos performáticos como una forma de aparición en lo público. La primera performance tematizó la pandemia y, particularmente, el proceso de vacunación y la segunda, los altos niveles de pobreza. Ambas ocuparon la calle, generaron polémica y permitieron ver el fuerte vínculo entre las derechas y los activismos virtuales. La metodología de nuestro estudio es cualitativa, basada en el análisis de los discursos de los referentes y en una etnografía virtual en diferentes redes sociales. Además, se describen, analizan y comparan las performances.
Performative Actions, Rights and Mediatization: the case of Jóvenes Republicanos (Argentina)
Authors: Camezzana Daniela , Capasso Verónica
Published: March 2023

ABSTRACT This article analyzes two actions carried out in 2021 by Jóvenes Republicanos (JR) - a right-wing Argentine political group - and their media coverage. The hypothesis is that JR adopts performative elements as a means to introduce themselves into the public sphere. Their first performance thematized the pandemic and, particularly, the vaccination process, while the second one, the high poverty rates. Both took over the streets, sparked controversy and allowed us to see the strong link between the right wings and online activism. The methodology used in this study is qualitative, based on the analysis of the discourses delivered by leaders and on the virtual ethnography of different social networks. The performances are also described, analyzed, and compared.
Despindo o Tempo: fendas eróticopolíticas no projeto cênico Strip Tempo - stipteases contemporâneos
Authors: Lordelo Lia da Rocha , Alencar Jorge
Published: March 2023

RESUMO Este artigo instiga relações entre uma criação artística e a sua composição com um tempo político em articulação com o projeto artístico baiano Strip Tempo - stripteases contemporâneos, em suas versões presencial e a digital, realizada na pandemia. Inicia-se com uma contextualização política e estética de tais performances; na sequência, conceitos da psicanálise e contribuições das artes burlescas dialogam com a proposta dos stripteases cênicos, além da noção de arquivo performativo. Como conclusão, afirma-se que os stripteases resumem, estética e eroticamente, os percursos de artistas contemporâneos e mobilizam discussões sobre o corpo nu, seja como última fronteira de uma moralidade ultraconservadora no Brasil de hoje ou como experiência de um desejo pulsional nas artes.
Estratificação Horizontal do Ensino Superior Brasileiro e as Profissões Imperiais: Os Concluintes de Medicina, Engenharia e Direito entre 2009 e 2017
Authors: Rodrigues Leonardo
Published: March 2023

Resumo O objetivo do artigo é analisar a estratificação horizontal do ensino superior no Brasil com enfoque nos cursos de engenharia, medicina e direito. Pretende-se investigar se essas áreas se diferenciam de acordo com o perfil socioeconômico de seus concluintes e se houve transformações nesse perfil em um período de rápida expansão do sistema de ensino. Resultados obtidos através de modelos multinomiais e de regressão logística indicam que esses cursos apresentam diferentes padrões de desigualdade de acordo com raça, sexo e escolaridade dos pais. O trabalho identificou uma diminuição nas desigualdades para o período analisado, mas com particularidades importantes entre as áreas e entre os tipos institucionais. As análises reforçam as hipóteses de que a estratificação horizontal pode ser um mecanismo de manutenção das desigualdades em períodos de expansão dos sistemas de ensino e que deve variar de acordo com o grupo profissional.

A Study on Reading Strategies for English Reading Class Using Movies: Focusing on the Movie Zootopia
Authors: Kim HyeJeong
Published: March 2023

This study aims to introduce reading strategies in which learners can directly participate and present class activities, using them to consider the activation of reading strategies. In addition, the study analyzes learners’ attitudes and reactions to using specific reading strategies to determine the points to be considered when using these strategies. The Disney animation, Zootopia (Howard & Moore, 2016), was used as a case study, and reading strategies focusing on the topics of prejudice, discrimination, and diversity were used. The research evaluation was based on an openended survey conducted in the last week of class and self-reflection notes drafted at the end of each week’s class. According to the survey, most learners were satisfied with the use of various reading strategies in reading classes using movies (70.3%). This satisfaction was mainly based on opinions that reading strategies helped learners to participate in class activities, understand movie topics, and efficiently focus on classes. Furthermore, it was found that when using movies in English reading classes, reading strategies centered on the movie themes may prove to be a sound approach. Therefore, it is necessary to further activate a theme-tailored reading strategy that uses various films with diverse and interesting themes.
