LEI E A ORDEM
Authors: Ribeiro William de Goes , Pereira Sheila Aparecida da Mota 
Published: August 2021

Distintas demandas e disputas podem ser percebidas nos mais variados contextos do campo educacional. Não obstante, também se diferenciam as concepções teórico-metodológicas da pesquisa em educação. Em uma abordagem discursiva, não essencialista, a partir da qual temos participado do debate curricular, rejeitamos uma unidade essencial e/ ou de fundamento último para o social. Assim, as exigências e/ ou solicitações diferenciais são reconhecidas como fluxos culturais, bem como efeitos de poder, uma vez produzidas no espaço-tempo aberto da enunciação, no qual o contexto é relevante para a comunicação, mas jamais estará dado tal como um sentido de totalidade para ser desvelado e meramente transmitido como cálculo. Dessa forma, procuramos contribuir com o debate no campo do currículo, compreendido como uma prática cultural sempre ambivalente, em que “o mesmo e o Outro” são iteradamente articulados na própria luta pela significação. Considerando a abordagem, buscamos o que está em jogo em algumas disputas políticas atuais, especificamente, no contexto de enunciação curricular articuladas por propostas de cunho reacionário e conservador. Para tal, propomos a leitura de três Projetos de Lei, os quais visam audaciosas alterações no campo: ensino religioso como solução para os problemas da educação; o criacionismo como conteúdo de ensino nas escolas; a criminalização dos docentes por assédio ideológico. Discutindo os projetos, esperamos contribuir com o debate, explicitando algumas reedições discursivas e as estratégias que põem em jogo, como a hibridização livre de discursos os mais variados, incluindo os do campo educacional.

ECOLE RURALE ET MONTAGNARDE FRANÇAISE
Authors: Champollion Pierre 
Published: August 2021

Dans ce chapitre consacré à l’école rurale et montagnarde française, l’auteur commence par interroger les différents concepts et notions nécessaires aux analyses présentées : d’abord, il questionne les concepts apparentés de « territoire » et de « territorialité », puis il cherche à cerner les notions d’espaces dits « rural isolé » et « de moyenne montagne » dans lesquels sont implantés la majorité des écoles rurales-montagnarde avant, enfin, de tenter de caractériser la « forme scolaire » de l’école rurale et montagnarde elle-même. Après cette introduction, il analyse successivement les principales dimensions qui traversent cette école particulière. L’école rurale et montagnarde française actuelle repose en effet sur plusieurs fondements plutôt positifs : une organisation adaptée aux spécificités du contexte territorial rural-montagnard, de bonnes performances scolaires notamment en langue maternelle et en mathématiques et, enfin, des pratiques professionnelles enseignantes prenant largement en compte les caractéristiques particulières de la ruralité et de la montagne (territorialités et publics notamment). En revanche, deux points la pénalisent assez clairement : d’une part, une formation professionnelle enseignante initiale quasi-inexistante sur ces spécificités territoriales attestées et, d’autre part, des politiques publiques d’éducation territorialisées souvent stigmatisantes pour la ruralité montagnarde et peu en phase avec ses besoins réels.
dor da solidão

Published: August 2021

O objetivo deste trabalho é analisar a dor da solidão, vivenciada pela personagem Lucrécia Neves, da obra A Cidade Sitiada, de Clarice Lispector, cuja manifestação máxima é a erotização do olhar. Nossa tese é a de que os investimentos libidinais, nas zonas oculares, estão associados à inveja excessiva, à ansiedade paranoide, a um superego arcaico avassalador, e, por conseguinte, a um Édipo mal sucedido, já estruturado no estágio oral da fase pré-genital, quando o ego ainda é muito imaturo para defender-se do poder tirânico dos instintos de agressividade, inveja e ódio, fatores preponderantes nos processos de introjeção dos objetos primordiais, sobretudo, a mãe. Desse modo, esta análise fundamenta-se, essencialmente, no pensamento de Klein (1996; 1981; 1975; 1974), no que tange aos seus conceitos de inveja, ansiedade paranoide e superego arcaico. A nosso ver, a solidão de Lucrécia Neves remonta à cena primordial, aos anseios persecutórios, expressões de seu recalque edipiano.
O QUE É UMA BOA AULA?
Authors: Cortez Noronha Ana Carolina 
Published: August 2021

Buscando jogar alguma luz sobre como se concebe a transmissão do conhecimento e a construção do saber nas escolas no Brasil no início do século XXI, fizemos uma análise discursiva de planos de aula disponíveis online em um site do MEC, que foi parte de nossa pesquisa de doutorado (defendido em dezembro de 2020). Entendemos que os planos de aula trazem, em um texto, a concepção do professor do que seja uma aula, bem como seu fazer interpretativo sobre os documentos legais que regem a educação brasileira e seu fazer persuasivo sobre dois sujeitos: o professor destinatário do plano de aula e os alunos, destinatários da aula. Trazem também a concepção de aula do Ministério da Educação que, ao aprovar as aulas que foram disponibilizadas em seu site, permite que apreendamos suas considerações sobre elas. Para essas análises, utilizamo-nos da teoria semiótica discursiva, apoiando-nos mais fortemente em Diana Luz Pessoa de Barros (2001), José Luiz Fiorin (2002), Greimas (2014 [1980]) e no Dicionário de Semiótica, de Greimas e Courtés (s/d [1979]). Este artigo, que apresenta parte de nossa tese, traz uma análise do tutorial “Como criar uma aula”, do site Portal do Professor, do MEC, de 2008, que ensina como se deve fazer uma aula para que seja publicada no Portal. Nosso objetivo, a partir dessa análise, foi apreender o que se entende como uma “boa aula”, objeto de valor buscado pelo sujeito que vai até esse site.

Published: August 2021

O presente trabalho é fruto de reflexões levantadas durante o mestrado das autoras sob a orientação da professora, também envolvida no processo de escrita . A proposição partiu da presença das propagandas, tanto no meio físico, quanto no meio digital. O trabalho com os textos de forma contextual, por meio dos gêneros, que emergem do social é uma recomendação recorrente nos documentos oficiais. As propagandas em sua construção fazem uso de diversas semioses, consideramos-na aqui enquanto exemplo de texto sincrético, que pode ser definido segundo Teixeira(2009) como a associação de múltiplas linguagens orquestradas de maneira a alcançar uma unicidade de sentido. O embasamento teórico desta pesquisa parte da semiótica discursiva, Greimas(1975), nos estudos e desdobramentos desenvolvidos por Floch(1986), Fiorin(2000) e Teixeira (2008 e 2009). Teixeira(2009) elabora uma proposta metodológica de análise dos textos sincréticos, na qual discorre sobre as categorias de análise do plano da expressão, que são cores (cromática), formas (eidética) e organização do espaço (topológica) e suas contribuições na produção do sentido e a relação dessas com o plano de conteúdo. Balizadas por essa propositura, analisamos uma propaganda e propomos uma sequência didática de leitura e produção do gênero para os anos finais da educação básica.

Abstract

OBJECTIVE
To compare the effects of tiludronate disodium and 3 other medical treatments on clinical and radiographic findings and biomarkers of disease progression in horses with osteoarthritis of the fetlock joint.

ANIMALS
100 Standardbred racehorses with spontaneous traumatic injury of the fet-lock joint.

PROCEDURES
Horses were retrospectively grouped by whether they received tiludronate IV or triamcinolone acetonide and hyaluronan, polysulfated glycosaminoglycan, or interleukin-1 receptor antagonist protein intra-articularly. Data were collected on clinical, radiographic, and ultrasonographic findings and results for serum and synovial samples obtained before and 6 months after treatment. Lameness score, joint flexion test response, radiographic score, serum concentrations of tumor necrosis factor-α and carboxy-terminal telopeptides of collagen types I and II (CTX-I and II, respectively), and synovial fluid concentrations of interleukin-1β, prostaglandin E2, and CTX-II were compared among treatments.

RESULTS
All treatments resulted in a significant improvement in lameness score and joint flexion test response at 6 months. In horses that received triamcino-lone acetonide and hyaluronan, synovial fluid interleukin-1β, prostaglandin E2, and CTX-II concentrations decreased after treatment, suggesting this treatment inhibited progression of hyaline cartilage degeneration and inflammatory processes. Horses that received tiludronate were the only group that had a decrease in radiographic score and serum CTX-I concentration after treatment, supporting the effect of tiludronate on bone metabolism. Tiludronate treatment was also followed by increases in serum and synovial fluid concentrations of CTX-II, a marker of cartilage damage.

CONCLUSIONS AND CLINICAL RELEVANCE
Tiludronate appeared to inhibit the radiographic progression of osteoarthritis in high-motion joints of racehorses at 6 months after treatment by inhibiting subchondral bone remodeling. Whether this effect was associated with a worsening of progressive cartilage damage remains to be ascertained.
Frames associated with shift invariant spaces on positive half line
Authors: Ahmad Owais , Ahmad Mobin , Ahmad Neyaz 
Published: August 2021

Abstract
In this paper, we introduce the notion of Walsh shift-invariant space and present a unified approach to the study of shift-invariant systems to be frames in L2(ℝ+). We obtain a necessary condition and three sufficient conditions under which the Walsh shift-invariant systems constitute frames for L2(ℝ+). Furthermore, we discuss applications of our main results to obtain some known conclusions about the Gabor frames and wavelet frames on positive half line.

Hedging functions of extraposed that-clauses in English and declarative subject da-clauses in Croatian academic writing
Authors: Varga Mirna 
Published: August 2021

Abstract
In academic writing stance is often conveyed by means of extraposed that-clauses (It is possible that the results were misinterpreted.). The impersonal form of a matrix predicate allows writers to express attitudes without assuming responsibility for the claim, which renders extraposition particularly convenient for hedging (Biber et al., 1999). The equivalent clause type in Croatian refers to declarative subject da-clauses (Moguće je da su rezultati krivo protumačeni.). The study examines the hedging potential of the target clauses in research articles in English and Croatian. Raising awareness of the way hedged stance is conveyed in cross-cultural academic writing may provide important implications for academic writing instruction particularly in a non-native English context.
Corpus based study of verbs explain and clarify as an example of assistance in pedagogical settings
Authors: Séguin Maja 
Published: August 2021

Abstract
The use of synonymy and near-synonymy allows us to differently express similar ideas and meanings, as well as perspectives. However, their use and nuances may be unclear to language learners, such as the selected case of the verbs explain and clarify. This paper examines the usage of the two verbs by looking into corpus data and uses Sinclair's methodological procedure as an alternative to dictionary references. Also included is a discussion of aspects and criticisms of corpus linguistics, mentions (and uses of) computer technologies for the analysis of language by discovering usage patterns, significant exceptions and semantic prosody, and exploring whether using corpora in the classroom would be beneficial to language learners.
Differences in EFL learners’ burnout levels and receptive language skills with regard to the mindfulness-based instruction
Authors: Moghadam Haniyeh , Ghanizadeh Afsaneh , Ghonsooly Behzad 
Published: August 2021

Abstract
The main aim of education is to provide students with academic knowledge and skills. In this process, some students experience burnout, which negatively affects their productivity and effectiveness. This study experimentally examines the impact of mindfulness-based instruction on burnout and students’ achievement in receptive language skills among 64 learners of English as a foreign language (EFL) via a mixed-methods approach (QUAN→ qual) within a single framework. The techniques implemented in the experimental group, i. e. 32 participants, included observance of all experience, analyzing, planning, judging, reasoning, and fantasizing (van Vreeswijk et al., 2014). Furthermore, the techniques were inspired by Pirson et al. (2012) conceptualization that mindfulness comprises novelty producing, novelty seeking, engagement, and flexibility. The results of posttest revealed these techniques efficiently enhanced the abovementioned variables.
MiR-182/Sestrin2 affects the function of asthmatic airway smooth muscle cells by the AMPK/mTOR pathway
Authors: Xiao Yali , Zhu He , Lei Jiahui , Xie Jing , Wu Ke , Gu Wenbo , Ma Jinxin , wei Dongxue , Shu Zhenhui , Zhao Limin 
Published: August 2021

Abstract

Background and Objectives
Asthma is a chronic inflammatory airway disease and brings heavy economic and spiritual burdens to patients’ families and the society. Airway smooth muscle cells (ASMCs) afect the development of asthma by secreting cytokines, growth factors, and prostates. The stress-inducing protein, Sestrin2, plays a vital role in antioxidant defense. The aim of this study is to investigate the role of Sestrin2 in asthma and its corresponding molecular mechanism.

Materials and Methods
Airway remodeling was induced by construction of asthma rat model. Primary ASMCs were isolated through combining tissue block adherence and enzymatic digestion and identified by immunofluorescence staining. Gene expression was measured by quantitative real-time PCR (qPCR) and western blot (WB) experiments. Cell viability, proliferation, migration, and calcium flow of ASMCs were measured by Cell Counting Kit-8 (CCK-8), 5-ethynyl-deoxyuridine (EdU), Transwell, and Fluo-3AM, respectively. The binding of miR-182 and Sestrin2 3′-untranslated region (3′-UTR) was measured by luciferase reporter system and RNA-binding protein immunoprecipitation (RIP) analysis.

Results
Sestrin2 expression was upregulated in asthma rat model and cell model. Overexpression of Sestrin2 enhanced the growth, migration, and calcium flow, and inversely, repression of Sestrin2 was reduced in ASMCs from the asthma group. MiR-182, one of the microRNAs (miRNAs) that possesses the potential to regulate Sestrin2, was downregulated in ASMCs from the asthma group. Further experiments revealed that Sestrin2 was inhibited by miR-182 and that overexpression of Sestrin2 reversed the miR-182–induced inhibition of the cellular progression of ASMCs from the asthma group. This study further investigated the downstream signaling pathway of Sestrin2 and found that increased expression of Sestrin2 activated 5′-adenosine monophosphate-activated protein kinase (AMPK), leading to the inactivation of mammalian target of rapamycin (mTOR) and thus promoting the growth, migration, and calcium flow of ASMCs from the asthma group.

Conclusion
This study investigated the role of Sestrin2 for the first time and further dissected the regulatory factor of Sestrin2, ultimately elucidating the downstream signaling pathway of Sestrin2 in asthma, providing a novel pathway, and improving the understanding of the development and progression of asthma.
The influence of sulfur addition on the hazard-type reaction of ilmenite ores with sulfuric acid
Authors: Jabłoński Maciej , Lubkowski Krzysztof , Tylutka Sandra , Ściążko Andrzej 
Published: August 2021

Abstract
The paper presents results of thermokinetic investigation of the hazard-type reaction of Norwegian and Australian ilmenite ores with sulfuric acid, modified by the addition of elemental sulfur, to increase the process safety in industrial conditions. In the reactions of both ilmenite ores the addition of sulfur caused a reduction of the thermal power generated in the reaction and a decrease in the value of the thermokinetic parameter ΔTmax/Δτ for almost the whole range of initial concentrations of sulfuric acid. It was also found that the addition of sulfur to the reaction did not negatively affect the degree of ilmenite leaching. The interpretation of the obtained thermokinetic curves allowed to determine safe process conditions for both types of titanium raw materials.
Nickel catalyst in coupled plasma-catalytic system for tar removal
Authors: Woroszył-Wojno Joanna , Młotek Michał , Ulejczyk Bogdan , Krawczyk Krzysztof 
Published: August 2021

Abstract
Tar formation is a significant issue during biomass gasification. Catalytic removal of tars with the use of nickel catalyst allows to obtain high conversion rate but coke formation on catalysts surface lead to its deactivation. Toluene decomposition as a tar imitator was studied in gliding discharge plasma-catalytic system with the use of 5%, 10% and 15% by weight Ni and NiO catalyst on Al2O3 (α-Al2O3) and Peshiney (γ-Al2O3) carrier in gas composition similar to the gas after biomass pyrolysis. The optimal concentration of nickel was identified to be 10% by weight on Al2O3. It was stable in all studied initial toluene concentrations, discharge power while C7H8 conversion rate remained high – up to 82%. During the process, nickel catalysts were deactivated by sooth formation on the surface. On catalysts surface, toluene decomposition products were identified including benzyl alcohol and 3-hexen-2-one.
