“Intrusos Divinos”. El culto a Tláloc en el Occidente de México
Authors: González Rizo Jesús Erick
Published: February 2021

Tláloc es una de las deidades panmesoamericanas más emblemáticas; sin embargo, si bien se reconoce su presencia en el Occidente de México, aún no quedan claras las particularidades de su culto en la región. Se ha detectado una fuerte presencia del culto a la deidad acuática en el sur de Jalisco y la cuenca de Chapala. La presente investigación retoma el tema, analizando de manera general la evidencia arqueológica y etnohistórica disponible sobre ello; se hace especial énfasis en la distribución espacial de los hallazgos de imágenes de esta deidad. Se parte del supuesto de que la adoración a este dios no fue para nada homogénea en los territorios que integrarían posteriormente los estados de Jalisco y Colima. 

   Se propone que la llegada del culto al dios de la lluvia a la región fue tardía, esencialmente durante el periodo Posclásico (900-1521 dC). El culto de Tláloc en la zona estaría asociado a la expansión territorial de la Tradición Aztatlán. Por contraste, la devoción por esta deidad estuvo prácticamente ausente en áreas donde predominaron cultu-
 ras materiales locales (por ejemplo, Complejos cerámicos Atemajac y Amacueca). Además, se hace notar cómo los atributos e iconografía de Tláloc fueron asimilados a los de otras deidades locales como parte del complejo escenario de interacción cultural del Posclásico mesoamericano.

¿Por qué presentar un monográfico sobre la movilidad infantil y adolescente y los retos que enfrentan sus protagonistas? Durante las últimas décadas, la niñez y la adolescencia se han convertido en un actor emergente de las migraciones internacionales, a pesar de estar todavía hoy invisibilizadas en los estudios migratorios. De manera preponderante, éstos se han venido ocupando del papel de la población adulta en los procesos de movilidad, principalmente desde una perspectiva ocupacional y economicista (Valdéz 2019). La centralidad de los estudios migratorios en la población adulta en edad productiva ha relegado a niñas, niños y adolescentes a un papel de pasividad y dependencia (Zúñiga 2017), cuando no, de total invisibilidad (Valdéz 2012). De aquí, la necesidad de dar luz y voz a estos sujetos para dinamitar el adultocentrismo desde el que hoy siguen siendo tratados a través distintas disciplinas científicas -y desde la sociedad misma-, así como la jerarquía en la producción de conocimiento sobre “otros” agentes del fenómeno migratorio. Estos son los objetivos principales de este monográfico.

Published: February 2021

Twenty-first century English language teaching is the witness of advanced Information and Communication Technology (ICT). Integrating digital technologies in English teaching activities is a prerequisite to enhance learning efficacy and achieve the goal of English communicative competence. Hence, this study examines the impact of flipped learning instruction on pragmatic competence of a group of English for specific purposes students’, i.e. English for Accounting. This pre-experimental study was conducted in ten meetings by involving 36 English for Accounting students of a public university in Surakarta Indonesia as the participants. Drawing on a Discourse Completion Test (DCT) and Focus Group Discussion (FGD), the results portrayed that there was a significant difference between the results of pre-test and post-test on DCT, meaning that the students’ pragmatic competence significantly improved after participating in the flipped learning instruction. An FGD was further conducted to reveal the students’ attitudes about the practice of flipped learning and the results indicated that they positively perceived the implementation of the teaching model in English for Accounting class. These results contribute to offering fruitful insights for teachers and future researchers about the practice of flipped learning instruction in English language teaching, particularly in the context of English for specific purposes.  Keywords: English for Accounting, Flipped Learning, Pragmatic Competence
UMA PESQUISA NARRATIVA VIVIDA EM MONITORIAS DE LÍNGUA PORTUGUESA COM DISCENTES INDÍGENAS EM UMA UNIVERSIDADE PÚBLICA NO BRASIL
Authors: Ferreira Thaís , Bengezen Viviane
Published: February 2021

Nesta pesquisa narrativa, uma aluna do curso de Letras e sua orientadora de TCC narram sua jornada de repensar as monitorias de português para estudantes indígenas em uma universidade federal da região Centro-Oeste do Brasil, buscando compreender quem são e quem estão se tornando em relação aos discentes e à pesquisa e quais as concepções de língua(gem), ensino e aprendizagem tiveram como base para suas ações. A perspectiva teórico-metodológica é a pesquisa narrativa segundo Clandinin e Connelly (2015), que têm como foco de investigação as experiências individuais vividas e narradas por meio de histórias, partindo do conceito de experiência conforme Dewey (1938) – com os critérios da continuidade e da interação. Como fundamentação teórica, as autoras baseiam-se no ensino de gêneros orais e escritos no âmbito acadêmico (MAGALHÃES; CRISTOVÃO, 2018; DOLZ, 2014; DIONISIO, 2011; ABREU-TARDELLI e LOUSADA, 2007) e nas concepções e visões de mundo dos pensadores indígenas (WERÁ, 2018, 2019; POTIGUARA, 2019; KRENAK, 2019). Os resultados da pesquisa são cinco histórias co-compostas colaborativamente: Preconceito linguístico e foco na gramática; O perigo da história única sobre o discente indígena; O que faz sentido no ensino de português para indígenas?; O início da transformação com um novo plano de trabalho e Um recomeço com comunidades responsivas e trabalho colaborativo.
O “BRASILEIRO” COMO LÍNGUA DE AFIRMAÇÃO EM PORTUGAL
Authors: Behling Janaina
Published: February 2021

O presente artigo é fruto de uma investigação desenvolvida num doutoramento na Universidade de Coimbra. Seu tema central é o impacto do português do Brasil, doravante “brasileiro”, em espaço português, tema a ser escrutinado por meio de três categorias:  o “brasileiro” como língua impossível, o “brasileiro” como língua possível e o “brasileiro” como língua de afirmação em Portugal. Devido não apenas às tradições e contradições históricas e identitárias da língua portuguesa neste país, mas também às reais e imaginárias rupturas materializadas pela linguagem, o artigo se justifica pela necessidade de que sejam estabelecidos engajamentos acerca da percepção de impactos, desafios e perspectivas de uma abordagem transgressiva ao português, uma vez contabilizados diferentes recursos metodológicos de documentação crítica.
DURANTE LEITURA, ESTÍMULOS VISUAIS, COMO A IMAGEM DO(A) AUTOR(A), PODEM PREJUDICAR O DESEMPENHO DE LEITORES
Authors: Lima Wagner
Published: February 2021

Durante a leitura, estímulos visuais, como a imagem fotográfica do(a) respectivo(a) autor(a), podem influenciar a compreensão textual de leitores juvenis? Essa questão motivou um estudo sobre significados outros, presentes na comunicação, além do significado do falante. Assim, um grupo de alunos de 9. ano escolar (n = 26) foi solicitado a ler textos em dois níveis de multimodalidade (unimodal (só texto) vs bimodal (texto + foto)); e a executar testes de inferências específicos (escolha de alternativas) acerca do assunto lido (testes de inferência). No final, cada participante informou, em uma escala ordinal (1 a 10), seu nível de certeza quanto à escolha feita por ele (testes de avaliação). Os dados encontrados apontam para a existência de efeito de bimodalidade sobre as inferências acerca dos textos (p = 0.000). E isso foi reforçado pelos resultados dos testes de avaliação. Contudo, uma análise mais minuciosa, considerando o tema dos textos como variável independente (texto a “As redes sociais” vs texto b “Gravidez na adolescência”), mostrou que o efeito observado foi de interferência e não de facilitação, como era esperado. Isso foi evidenciado especialmente na situação de leitura do texto a (p = 0.01). Em suma, entre leitores juvenis, as fotos não funcionaram como dicas extraverbais, nem foram relevantes para a compreensão leitora. Portanto, conclui-se que a expressividade do(a) autor(a) contribui exclusivamente com a recepção da mensagem, e não com a compreensão do significado do texto.

OS ERROS DE PONTUAÇÃO DE REDAÇÕES NOTA MIL DO ENEM À LUZ DA HIPÓTESE DA PROSÓDIA IMPLÍCITA E DA FONOLOGIA PROSÓDICA
Authors: Virgínia Silveira Baldow  , Santos Alcione , Vera Pacheco
Published: February 2021

Este artigo objetiva discutir usos não-convencionais de vírgulas em redações nota mil do ENEM à luz dos pressupostos teóricos da Fonologia Prosódica e da Hipótese da Prosódia Implícita. Com a discussão empreendida, defendemos que o uso não-convencional da vírgula pelos escreventes apresenta regularidades prosódicas que podem ser guiadas pela organização mental da prosódia da fala de que dispõem os falantes que é, de algum modo, projetada para a escrita, fato que também explica as razões pelas quais os avaliadores não se aperceberam das incorreções nos textos investigados.  Os resultados mostraram que, embora o uso da vírgula seja associado, em geral, a fatos sintáticos, ela pode atuar como um marcador prosódico, delimitador fronteiras de frases entoacionais.

Authors: De Abreu Kátia Nazareth Moura , Da Hora Katharine , Pinheiro Ana Cristina
Published: February 2021

O presente trabalho aborda o tema da compreensão leitora de alunos do sétimo ano do Ensino Fundamental. Foi feito um estudo longitudinal, tendo como base teórica os estudos de Kintsch e Rawson (2013), Perfetti, Landi, Oakhill (2013) e de Kato (1985, 1986), Morais (1996) e Maia (2018, 2019) e como base metodológica a técnica de Cloze divulgada por Taylor (1953), Santos et al (2004) e Santos, Boruchovitch, Oliveira (2009). O objetivo foi mostrar que as atividades de leitura realizadas por meio de ensino sistemático envolvendo metacognição, metalinguagem e consciência sintática podem conduzir ao aprimoramento da compreensão leitora. Foram aplicados dois testes de Cloze em etapas avaliativas, uma no início e outra ao final da pesquisa, além de cinco atividades-teste durante a intervenção. O estudo sugere um crescimento significativo em compreensão leitora dos alunos no segundo teste, aplicado após a metodologia interventiva, apontando para um impacto positivo de ações pedagógicas baseadas em metacognição, metalinguagem e consciência sintática para o desenvolvimento da compreensão leitora.

Published: February 2021

Esta pesquisa buscou estudar os aspectos expressivos e cognitivos no contexto de pessoas com síndrome de Down (SD), através da investigação da relação entre as dificuldades da memória operacional e de linguagem expressiva. Como também traçar reflexões sobre essa relação e possíveis caminhos de colaboração com o público abordado. Os procedimentos metodológicos envolveram a avaliação de 15 indivíduos com SD com idades entre 07 e 26 anos que faziam parte de um projeto de extensão vinculado a uma Instituição de Ensino Superior da Paraíba. Foi realizada avaliação do vocabulário expressivo através de nomeação de imagens; avaliação da memória de trabalho através dos testes de repetição de não palavras e de dígitos. Os resultados no teste de vocabulário expressivo demostraram uma média de 64.60 % de designações verbais usuais (DVU), nas provas de memória de trabalho a média dos resultados foi de 31,36 pontos na prova de não palavras, e na prova de dígitos de ordem direta a média foi de 5,57 pontos. O desempenho na prova de não palavras sofreu influência da extensão da palavra, ou seja, quanto maior o número de sílabas pior foi o desempenho dos indivíduos. A correlação entre o teste de memória e vocabulário mostrou-se significante, o que significa que quanto melhor o resultado nos testes de não palavras e de ordem de dígitos (avaliação da memória de trabalho) melhor foi o desempenho no teste de vocabulário expressivo. Não houve relação significativa entre as variáveis idade, escolaridade e alfabetização com os testes de memória e de vocabulário expressivo.
PROCESSAMENTO DE INFERÊNCIAS DE CAUSA NA LEITURA DE SENTENÇAS
Authors: Santos Sabrina
Published: February 2021

Este trabalho investigou o processamento de sentenças com relações de inferência de causa interoracionais, comparando dois grupos de diferentes níveis de formação escolar, a saber, Ensino Fundamental (EF) e Ensino Superior (ES). Por meio de técnica de rastreamento ocular, contrastaram-se dados experimentais da leitura de sentenças com relações de causa direta (e.g. A aluna recebeu os parabéns porque/já que ela obteve sucesso no exame do ENEM), e de causa indireta (e.g. A aluna escreve textos bons porque/já que ela obteve sucesso no exame do ENEM.) avaliando também a influência dos conectivos (já que e porque) utilizados para articular as orações. As perguntas de pesquisa foram: se e de que modo a experiência em leitura influencia no processamento de sentenças que estabelecem coerência de causa por mecanismos inferenciais distintos. As hipóteses levantadas foram as de que: i) as relações de causa indireta apresentam maior custo de processamento do que as relações de causa direta, pois requerem geração de inferências a partir do conhecimento de mundo do leitor; ii) as propriedades gramaticais dos conectivos levam a maior, ou menor, facilitação do processamento da sentença; iii) há correlação entre baixa habilidade em leitura e dificuldades de parseamento. Esse trabalho buscou construir um diálogo entre a Psicolinguística e a Educação Básica, fornecendo dados experimentais que possam vir a contribuir para o desenvolvimento de materiais e de práticas pedagógicas de ensino-aprendizagem da leitura.

Published: February 2021

Abstract Background: The diagnostic importance of three-dimensional (3D)
speckle-tracking strain-imaging echocardiography in patients with acute
myocarditis has not yet been assessed. The aim of this study was to test
the sensitivity and specificity of 3D-speckle-tracking echocardiography
as compared to CMR (cardiovascular magnetic resonance imaging) for the
diagnosis of acute myocarditis. Methods and Results: 45 patients that
were admitted to the Medical Clinic II of the University Hospital Bonn
with clinically suspected myocarditis were enrolled in our study (71%
male, mean age: 43.9±16.3 years, peak troponin level: 1.38±3.51 ng/ml).
3D full-volume echocardiographic images were obtained and offline
speckle-tracking analysis of regional and global LV deformation was
performed. All patients received CMR scans and myocarditis was diagnosed
in 29 subjects. The 16 patients, in whom myocarditis was excluded by
CMR, served as controls. Regional changes in myocardial texture and
tissue edema (diagnosed by CMR) were significantly associated with
regional impairment of circumferential, longitudinal, and radial strain,
as well as regional 3D displacement and total 3D strain. The 3D
diastolic strain index was not associated with pathological findings in
the CMR. However, the 3D global longitudinal strain (GLS) outperformed
well-known 2D parameters associated with myocarditis, such as LVEF and
LVEDV. Conclusions: This is the first study examining the use of
3D-speckle-tracking echocardiography in patients with acute myocarditis.
Global longitudinal strain was significantly associated with and
impaired in patients with myocarditis. Therefore, 3D echocardiography
could become a useful diagnostic tool in the primary diagnosis of
myocarditis.

Published: February 2021

Based on the structure-oriented lumping method, a molecular-level
reaction kinetic model of the delayed coking process, which adopted 24
structural increments to construct the feed molecular matrix containing
2,944 molecules, was established with a reaction network containing
74,581 reactions using MATLAB. The reliability of the model was verified
by experimental results. According to the discriminant rules of
structural increments, 173 structural vectors in gasoline and 1,132
structural vectors in diesel were classified into different group
compositions, respectively. The model could track the reaction path of
any specific molecule in the complex thermal cracking reaction network.
The influences of operation conditions such as recycle ratio on the
product distribution could be discovered through the calculation of the
molecular-level model, which is helpful for the process optimization and
precise regulation of product composition for the delayed coking plants.
The Diagnostic Value of 2D- Speckle Tracking Echocardiography for Identifying Subclinical Ventricular Dysfunction in Subjects with Early Repolarization Pattern
Authors: Çöllüoğlu Tuğçe , Onalan Orhan , Çakan Fahri
Published: February 2021

Introduction: Early repolarization pattern (ERP) has been known a benign
electrocardiographic variant for decades. However, it can exist a silent
substrate for arrhytmic events in accordance with the previous studies
which have shown that there has been evidence of morphological changes
in left ventricle (LV) in subjects with ERP. Despite structural changes
in ERP subjects, it has not exactly known that whether a change in
functional parameters of LV occur in these population. The aim of our
study was to investigate LV functional parameters in subjects with ERP
by the use of 2D- speckle tracking echocardiography (2D-STE). Method: In
this study, subjects with ERP (n= 50) and subjects without ERP (n= 50)
were recruited between 01.04.2018 and 01.09.2018. For each case, 2D- STE
evaluation was performed by the same cardiologist. Results: Mean LV
global longitudinal strain (GLS) and GLS in all apical chamber views,
longitudinal peak systolic strain rate (SRS) at A3C, early diastolic
strain rate (SRE) at A3C and late diastolic strain rate (SRA) at A3C in
the ERP subjects were significantly lower than those in the subjects
without ERP. Furthermore, LV basal segment circumferential SRS and SRE
were significantly lower in ERP subjects compared to subjects without
ERP. Conclusion: Our study suggests that ERP can be more associated with
impaired LV longitudinal function than LV circumferential function. In
addition, both LV inferolateral region and LV basal segment can be more
affected functionally in ERP subjects.
Impact of Latvian wood construction cluster on the economic efficiency of its members
Authors:   Latvia University of Life Sciences and Technologies, Muska Aina , Mazure Gunita ,   Latvia University of Life Sciences and Technologies
Published: February 2021

The operation in the cluster allows merchants increase their operational efficiency, productivity, exportability and gain other benefits. The establishment of Latvian Wood Construction Cluster at the beginning of 2012 was targeted at promotion of the cooperation within the industry by developing the potential of production and export markets. The research aim is to study the changes in the economic efficiency of the merchants belonging to Latvian Wood Construction Cluster. Six Cluster members, whose economic efficiency was measured consistent with the methodology developed by the research authors, were selected for the validation or rejection of the research hypothesis and achievement of the research aim, which was advanced following the recommendation of the experts. The research results lead to the conclusion that the economic efficiency of the merchants under the study has not improved during the Cluster performance period; it has even worsened, especially for “Nordic Homes”, “HUSVIK”, “Dores fabrika” and “Cross Timber Systems”, compared with the average industry figure. Nevertheless, the net sales, operating profit and net profit of “BYKO–LAT” have increased during the Cluster performance period and the achieved results have significantly surpassed the average industry figures, the merchant’s economic efficiency did not present an improvement during the Cluster performance period due to the decline in return on assets, increase in production costs, decline in the profit to long-term capital ratio in 2017 and 2018 as well as the decrease in return on equity and commercial profitability in 2018. The authors explain the obtained research results by the fact that the Cluster activities are performed with the aim to inform on the Cluster operation, its members and wood construction; the Cluster activities are less targeted at the increase of economic efficiency.
Spending review as essential part of public sector budgeting: Latvian experience
Authors:   BA School for Business and Finance, Ketners Karlis
Published: February 2021

One of the modern trends in public sector budget governance is evaluation of allocation of the resources, re-allocation of budget resources to achieve political goals and ensure sustainable financing for different public needs. This study is the first analysis of Latvian experience of public spending reviews in 2016 – 2019, characterises present patterns and proposes changes for future spending reviews. In general, the Ministry of Finance is conducting public spending review as quite technocratic exercises – an opportunity to make sure that existing public institutions’ budgets are being spent as efficiently as possible and conduct decision making on the civil service level. However, involvement of political level is a possibility to ensure that public spending objectives are met and the allocation of public resources reflects policy goals. The main task of the paper is to analyse the Latvian experience of regular public spending reviews and generalize recommendations for other countries and future development of the spending reviews. It can be concluded that increasing prioritization of budgetary spending and its relation with economic development can be supported by spending reviews as a mechanism to increase government spending in priority policy areas and to ensure reallocation of resources for underfinanced budget programmes through improvement of the efficiency of expenditures. Recommendations on improvement of the spending review process and possible changes to the budget law legislation are worked out.
Evaluation of vehicle taxation in the Republic of Latvia by the method of variant optimization using relative single indexes
Authors:   Baltic International Academy, Leontyev Alexey , Reshina Galina ,   University of Latvia
Published: February 2021

The European Commission has evaluated the consequences of the Latvian tax reform in 2018 and declared that the set target of decreasing tax burden for people with low income was not reached, yet the tax reform continuing implementation caused even greater social stratification. The goal of the study was to develop method for determining the rational tax on vehicles based on criteria of fairness and efficiency using an analytical approach. To develop such a method for vehicle taxation, relative single indexes approach as a part of method of variant optimization was used based on relative fuel equivalent coefficient. To analyse the current situation in Latvia and show possible ways of improving it, scenario analysis (three controlling cases) and mathematical modelling by using the developed method were carried out. Analysis of the first controlling case showed that the current situation in Latvia's vehicle taxation policy is not efficient enough from the point of the combination of fairness and efficiency. To improve the situation and achieve zone of optimum (the third controlling case) it is possible to shift tax burden partially from local taxpayers to taxpayers with foreign-registered vehicles. To comply with the recommendation of the European Commission, it is also recommended to set fairness as a primary criterion and make the system more favourable to the taxpayer (when operating in the zone of optimum). It can be achieved by using annual mileage as a base to determine the tax. If recommendations would be implemented partially, it is possible to reach the state (the second controlling case), where vehicle taxation is becoming optimal, yet any change in tax rates or procedures separately will lead to ineffective or unfair solutions. Overall the developed method allows to analyse and forecast most of the changes in vehicle taxation.
Integer points enumerator of hypergraphic polytopes
Authors: Pesovic Marko
Published: February 2021

For a hypergraphic polytope there is a weighted quasisymmetric function which
enumerates positive integer points in its normal fan and determines its
f-polynomial. This quasisymmetric function invariant of hypergraphs extends
the Stanley chromatic symmetric function of simple graphs. We consider a
certain combinatorial Hopf algebra of hypergraphs and show that universal
morphism to quasisymmetric functions coincides with this enumerator function.
We calculate the f-polynomial of uniform hypergraphic polytopes.

Published: February 2021

Obesity has caused wide concerns due to its high prevalence in patients with severe coronavirus disease 2019 (COVID-19). Coexistence of diabetes and obesity could cause an even higher risk of severe outcomes due to immunity dysfunction. We conducted a retrospective study in 1,637 adult patients who were admitted into an acute hospital in Wuhan, China. Propensity score–matched logistic regression was used to estimate the risks of severe pneumonia and requiring in-hospital oxygen therapy associated with obesity. After adjustment for age, sex, and comorbidities, obesity was significantly associated with higher odds of severe pneumonia (odds ratio [OR] 1.47 [95% CI 1.15–1.88]; P = 0.002) and oxygen therapy (OR 1.40 [95% CI 1.10–1.79]; P = 0.007). Higher ORs of severe pneumonia due to obesity were observed in men, older adults, and those with diabetes. Among patients with diabetes, overweight increased the odds of requiring in-hospital oxygen therapy by 0.68 times (P = 0.014) and obesity increased the odds by 1.06 times (P = 0.028). A linear dose-response curve between BMI and severe outcomes was observed in all patients, whereas a U-shaped curve was observed in those with diabetes. Our findings provide important evidence to support obesity as an independent risk factor for severe outcomes of COVID-19 infection in the early phase of the ongoing pandemic.
FOXO1-Mediated Downregulation of RAB27B Leads to Decreased Exosome Secretion in Diabetic Kidneys
Authors: Zeng Mengru , Wen Jin , Ma Zhengwei , Xiao Li , Liu Yutao , Kwon Sangho , Liu Yu , Dong Zheng
Published: February 2021

Exosomes have been implicated in diabetic kidney disease (DKD), but the regulation of exosomes in DKD is largely unknown. Here, we have verified the decrease of exosome secretion in DKD and unveiled the underlying mechanism. In Boston University mouse proximal tubule (BUMPT) cells, high-glucose (HG) treatment led to a significant decrease in exosome secretion, which was associated with specific downregulation of RAB27B, a key guanosine-5′-triphosphatase in exosome secretion. Overexpression of RAB27B restored exosome secretion in HG-treated cells, suggesting a role of RAB27B downregulation in the decrease of exosome secretion in DKD. To understand the mechanism of RAB27B downregulation, we conducted bioinformatics analysis that identified FOXO1 binding sites in the Rab27b gene promoter. Consistently, HG induced phosphorylation of FOXO1 in BUMPT cells, preventing FOXO1 accumulation and activation in the nucleus. Overexpression of nonphosphorylatable, constitutively active FOXO1 led to the upregulation of RAB27B and an increase in exosome secretion in HG-treated cells. In vivo, compared with normal mice, diabetic mice showed increased FOXO1 phosphorylation, decreased RAB27B expression, and reduced exosome secretion. Collectively, these results unveil the mechanism of exosome dysfunction in DKD where FOXO1 is phosphorylated and inactivated in DKD, resulting in RAB27B downregulation and the decrease of exosome secretion.

STRUCTURAL AND SEMANTIC FEATURES OF OXYMORON IN “1984” BY G. ORWELL AND ITS TRANSLATIONS
Authors: CHIRSHEVA GALINA N. , CHERNIGA VALENTIN I.
Published: February 2021

The article provides the description of the structural and semantic features of oxymoron in G. Orwell's novel “1984” and its translations into Russian. The paper raises the problem of translatability of the oxymoron, compares the features of the oxymorons of the source text and its translations, and compares the features between translations. The research identifies that the authors of the translations tend to preserve the oxymoron: they don't usually change its structure and achieve the identity of the stylistic effect using antonymic relations similar to the original. Structural and semantic deviations can be caused by differences in language systems, lexical compatibility, and translation transformations.

Manusia adalah makhluk yang unik karena dalam beberapa hal dia memiliki hal yang sama dengan hewan. Namun, mansia memiliki akal yang membedakannya dari hewan manapun yang ada di dunia ini. Insting adalah sesuatu yang ada pada manusia dan hewan yang menjaga mereka agar tetap hidup, atau bisa disederhanakan bahwa insting adalah sebuah potensi kehidupan. potensi kehidupan ini tidak dapat diindera seperti layaknya benda, namun kita dapat memastikan eksistensinya dengan melihat penampakan ataupun manifestasinya dalam aktivitas manusia sehari-hari. Setidaknya ada dua potensi kehidupan pada manusia yang bisa diketahui. Pertama, potensi kehidupan yang berbentuk kebutuhan jasadiyah (needs). Kedua, potensi kehidupan yang berupa keinginan naluriah (wants).

Bunuh diri menjadi salah satu penyebab kematian terbanyak di dunia. Penelitian terdahulu menyebutkan bahwa sebagian besar individu yang memiliki ide bunuh diri tidak melakukan upaya bunuh diri, namun lebih banyak individu yang memiliki ide dibandingkan individu yang melakukan tindakan bunuh diri. Namun secara logis, tindakan bunuh diri diawali oleh ide bunuh diri. Peneliti melakukan telaah literatur terkait pengembangan ide bunuh diri menuju sebuah bentuk upaya bunuh diri pada individu. Ide bunuh diri merupakan pemikiran mengenai perencanaan, perilaku dan hasil tentang bunuh diri, kematian, serta perilaku yang merugikan diri sendiri. Faktor psikologis menjadi faktor dominan penyebab munculnya ide bunuh diri. Hasil dari kajian telaah literatur yang dilakukan menunjukkan bahwa ide bunuh diri berkembang menuju upaya bunuh diri akibat dari berbagai peristiwa dan pengalaman kehidupan individu

The aim of the study is to develop an idea of alternative science based on ideas in the history of philosophy. The novelty of the work lies in the creation of an idea of an alternative model of science, which allows solving the existing problems of modern science. The main research methods are hermeneutic and axiological, as well as a systems approach. The conclusion reached by the authors is that alternative science should not describe existing empirical realities but develop a scientific ideal. In turn, this scientific ideal must have a spiritual content, i.e. to be spiritualized. It must be recognized as the highest truth, and all other ideas that have their manifestation in our world, science must consider through comparison with a scientific spiritualized ideal.
Municipal services and peculiarities of regulating the process of their provision
Authors: Rudnev Rudnev
Published: February 2021

Despite the great social importance of providing services to the population, solving this problem is complicated at present by difficulties associated with the lack of a unified methodology for managing services at the level of municipal entities, state social minimum standards, and also not fully resolved issues of delimiting powers and subjects of jurisdiction between the levels of government. It is necessary to understand that the provision of services to the local population, among other things, is the basis for the multiplicative development of the economy of a municipal entity. In modern conditions, there is a need to make some clarifications in the conceptual apparatus, highlighting the services provided to the population on the territory of a municipal entity ensuring the life of the local community. Currently, the legislation of the Russian Federation does not contain a clear definition of municipal functions, services, and works. The legislative acts regulating the basis for the provision of municipal services do not cover the entire range of actually provided services and are not coordinated with each other.
Heutagogy: The pedagogy of agency
Authors: Blaschake Lisa
Published: February 2021

Even before Covid-19, higher education was facing a perfect storm of challenges: increased costs, reduced funding, and rising industry demand for more skilled graduates. Educators were also challenged with finding ways to better prepare students for an uncertain future where lifelong learning skills are essential. The current pandemic has only served to intensify the storm, and educational institutions have rushed to technology in order to survive. In response to the new — or next — normal, institutional leaders are attempting to adapt traditional curriculum and systems so that they can transition rapidly to remote teaching and learning. Online, hybrid, and hyflex learning have become the beguiling buzzword solutions of today. How to survive this perfect storm and the storms to come? This presentation will propose that it is not technology that will best address these challenges; instead, a fundamental rethinking of how we teach and learn is necessary. By adopting heutagogy — or a pedagogy of agency, where the learner takes control of learning — will we be able to agilely transition and pivot across delivery methods, while also equipping our students with the lifelong learning skills and competencies required for the future.
Evaluating efficiency of data flow transmission in network “captain of fishing vessel - company’s designated person”

Published: February 2021

The article considers the effective control of the company's vessels safety in the fishing area, which depends on the rational organization of information flows in the networks of safety management systems. There has been shown a directed graph demonstrating the model of dependence on the rational organization of information flows between the captains of ships and the appointed person of the company. The information redundancy in the “captain - designee” and “designee - captain” channels is stated to lead to congestion and omissions of important fishing and navigation messages. It has been found that for a given accuracy of predicting the data of the controlled parameters of the ship's safety, as well as for the given data transfer rate, the necessary tact in transmitting the data through the communication channels of the safety management system can be accurately estimated. There are considered two versions, when the random component obeys either the normal law or the exponential distribution law. The obtained ratios are analyzed to determine the amount of information and tact in its transmission for some technical and operational parameters of the vessel in the fishing area from the captain of the vessel to the designated person of the company. It is shown that by estimating the amount of information and the necessary speed of its transmission through the communication channels of the safety management system for each vessel, it is possible to build a rational system for managing the safety of the company's vessels in the fishing area.
Measuring diameter of water jets affecting propeller blade surface under cavitation wear

The article analyses the structure of cavitated areas of the ship propeller blades made from aluminum bronzes with different composition. The most informative zones of cavitation wear are the cold-hardening zone and the peripheral one that help estimate the mechanical parameters causing the cavities to collapse. The dents formed on the metal surface in the process of hydrodynamic cavitation wear have spherical parts on their bottoms, in which it is possible to inscribe a circle of a definite diameter. There were conducted the experiments on forcing the ball indentors into the surface of different metal alloys. The first run of the experiments includes forcing of a steel ball with a diameter of 1.588 mm into the surface of 33 alloys with different hardness under the loads of 1 470, 980 and 588 N. The impression diameters were measured using Brinell magnifying glass. There has been found the power dependence between deformation of dents on the metals tested under hydrodynamic cavitation and hardness of the materials, which is similar to the dependence of deformation after forcing the ball indentors into the alloys of different hardness. The second run of the experiments included modeling the cold-hardening zone of the cavitation wear area by repeated forcing the ball indentors with the diameters of 1.588, 2.5, 3.175 and 5.0 mm into the bronze BrAZhNMts9-4-4-1 plates with area of 100 × 50 × 20 mm. Forcing was made into the side 100 × 50 mm previously ground and polished. The equal strain rate in impressions of different diameters was observed during forcing. A direct proportional relationship was obtained between the arithmetic mean deviation of the surface profile and the indenter diameter. The arithmetical mean deviation of the assessed profile of the side plotted against the ball indentor yields a direct proportional relationship. Using the dependence for the case of cavitation attack on the propeller blades helps to infer that the diameter of water jets striking against the propeller blade surface with diameter of 3 700 mm makes about 10 mm. The obtained value allows to choose reasonably the experimental equipment and the parameters of testing the ship propeller materials for cavitation wear.
Three-dimensional numerical simulation of low-consumption inflow turbine with partial blading of runner
Authors: Kriukov Aleksei Alekseevich , Chekhranov Sergei Valentinovich
Published: February 2021

The article describes the inflow turbines as reliable, productive, small-sized drives for various units and devices. The practice of manufacturing and using inflow turbine stages sets out the goal of increasing efficiency, simplifying technology and reducing cost of manufacturing stages. Increasing the efficiency of inflow turbines requires solving the problems of improving the flow part and calculating the optimal geometry and operating modes of the impeller flow. A significant part of low-consumption inflow turbines is partial, which leads to additional losses. The use of fanless turbine stages reduces the losses caused by partiality by means of improving the design parameters. Such stages include turbines with partial blading of the runner, which have the distinctive features compared to conventional partial turbines. An innovative way to improve the design efficiency of these turbines is to determine the loss of kinetic energy in the nozzle and runner using the ANSYS CFX package. The geometric model is constructed using ANSYS Design Modeler, a grid is selected, and boundary conditions are set. There are shown the dependences of speed coefficients of a nozzle diaphragm and a runner of the turbine with partial blading in the range of expansion stage πt =1,5÷2,5, and the admission intensity in the range 0,059÷1. As a result of approximation, the empirical dependences are obtained that take into account the influence of the degree of partiality and the degree of expansion of the stage on the coefficients of speed of the nozzle diaphragm and the runner. The resulting empirical dependences are indispensable for modeling an inflow turbine.
