Authors: Santos Cintia Aparecida Bento dos , Zaran Mariana Lemes de O. , Curi Edda
Published: September 2022

Este artigo apresenta a síntese de uma dissertação de mestrado em Ensino de Ciências e Matemática que se desenvolveu no âmbito do projeto Observatório da Educação e teve como objetivo inicial investigar os procedimentos revelados por alunos de 5º ano do Ensino Fundamental em relação à resolução de problemas de estruturas multiplicativas. A pesquisa foi desenvolvida adotando um método qualitativo com técnica de análise documental, em que para pesquisa de campo foram utilizados quatro instrumentos contendo problemas dos grupos pertencentes às estruturas multiplicativas segundo o quadro teórico dos campos conceituais. Os sujeitos de pesquisa são alunos de uma escola pública da cidade de São Paulo participantes do projeto. Os resultados colocaram em evidência um cenário delicado em relação às interpretações dadas pelos educandos diante de situações propostas, em que, em alguns grupos de problemas, eles demonstraram fragilidades quanto à apropriação do raciocínio multiplicativo ou dos algoritmos que permeiam as operações. As considerações apresentadas ao final dos estudos propiciam a reflexão sobre intervenções que podem contribuir com o processo de ensino e aprendizagem no campo multiplicativo.

Este trabalho relata o desenvolvimento de um projeto que objetivou aplicar as metodologias de Teoria à Experimentação, em disciplinas de Física e Matemática do Ensino Médio relacionadas com o conteúdo programático de eletrônica e eletricidade, como estratégia de internalização dos conteúdos teóricos abordados. O projeto foi desenvolvido em um colégio estadual da periferia de Ponta Grossa/PR, e teve a duração de um ano com encontros semanais de aproximadamente 20 horas. O conhecimento desenvolvido pelos alunos participantes do projeto foi avaliado de forma processual, contínua e cumulativa, onde os principais instrumentos de avaliação foram: seminários no próprio colégio ou em eventos na universidade, relatórios dos experimentos, listas de exercícios conceituais e avaliações teóricas. Como resultados, pode-se verificar que 80% dos alunos envolvidos classificaram as práticas como essencial no aprendizado dos conteúdos e 100% deles apontaram a falta de um laboratório em seu colégio. Buscou-se treinar os alunos para que associassem as teorias abordadas nas disciplinas envolvidas com as práticas laboratoriais, buscando desenvolver raciocínio correlacionado, de modo a serem capazes de aplicar conceitos teóricos aos problemas enfrentados. Assim, desejou-se despertar o interesse destes alunos aos cursos de exatas, incentivando-os, ao final do ensino médio, a disputarem vagas dos cursos de Engenharia.
Objeto real versus ideal: consequências na constituição de sistemas semióticos para a aprendizagem intelectual
Authors: De Souza Roberta Nara Sodré , Moretti Méricles Thadeu
Published: September 2022

Neste ensaio desenvolvemos uma análise da diferenciação dos objetos real e ideal e a consequência disso na constituição dos sistemas semióticos para a aprendizagem intelectual. Em particular, a matemática trata desses últimos, objetos que não podemos ter acesso a eles nem com a ajuda de instrumentos como ocorre, por exemplo, na biologia com o microscópio. Para compreender as diferenças de aprendizagem nas mais diversas disciplinas é preciso ter em mente a natureza dos objetos que cada uma trata. A matemática, por tratar de objetos ideais, tem extrema necessidade de construir representações para poder trabalhar com eles. A semiose é condição necessária à aprendizagem em matemática; não basta tratar com a representação, é necessário não confundi-la com o objeto. Para a aprendizagem da matemática precisamos conectar os sistemas semióticos e, para isso, levaremos em conta principalmente: a teoria dos registros de representação semiótica desenvolvida por Duval e a ideia de semiosfera de Lotman que amplia as semioses para o aspecto cultural. No ensino da matemática evidencia-se contribuições na prática pedagógica, consideramos que as inter-relações entre os sistemas semióticos, potencializam a formação das noções em nossas mentes mostrando essencial essa consciência do docente na elaboração de atividades que contemplam determinado(s) objeto(s).

Published: September 2022

Resumo

 O trabalho com temáticas ambientais nas abordagens educativas pode receber grande apoio de atividades práticas contextualizadas, pois propõe uma relação mais consistente entre o conteúdo a ser estudado e o cotidiano do aluno na busca da promoção de reflexões e ações que favoreçam a formação dos futuros cidadãos. Neste trabalho optou-se por desenvolver o tema “Água” por meio de uma contextualização interdisciplinar, fundamentada nos conceitos de Química envolvidos no tratamento de água. O objetivo foi promover o aprendizado referente ao tratamento de água no contexto do Ensino de Química e de Educação Ambiental, a partir da aplicação de um kit didático simulador do teste de jarros, construído com materiais reutilizados, para demonstração em espaços educativos. Foi desenvolvida uma atividade pedagógica composta por diversas modalidades didáticas a grupos distintos de alunos do 9º ano do Ensino Fundamental II e 1º ano do Ensino Médio, onde foi promovida uma palestra interativa, com funcionamento concomitante do kit, além da aplicação de questionários prévios e posteriores. Interligar concepções e ações científico-pedagógicas com uma abordagem dinâmica possibilitou uma visão ampliada de que a aprendizagem sobre o tratamento de água pode ser potencializada com atividades didáticas contextualizadas motivadoras.

Authors: Da Costa Denise Kriedte , Cury Helena Noronha
Published: September 2022

Neste artigo, são apresentados os resultados de um mapeamento de dissertações e teses sobre interdisciplinaridade, defendidas em programas de Pós-Graduação em Ensino de Ciências e Matemática do Rio Grande do Sul. A partir de considerações teóricas sobre o tema “interdisciplinaridade” e de apontamentos sobre as pesquisas do tipo estado da arte, os dados de 63 produções, apresentados em quadros e gráficos, são analisados. Constata-se que a maior parte dos trabalhos investiga os anos finais do Ensino Fundamental e o Ensino Médio e a produção se distribui, principalmente, entre as que abordaram dois ou mais enfoques e as que trabalharam com Educação Ambiental. A partir dessa coleta de dados, considera-se que as investigações sobre interdisciplinaridade deveriam, também, ser realizadas em cursos de graduação e pósgraduação, especialmente levando em conta que a formação inicial e continuada de professores de Ciências e Matemática precisa se voltar para essa temática que pode integrar disciplinas, níveis e modalidades de ensino.

Desiccation characteristics and direct tension attributes of thin clayey soil containing discrete natural fibers
Authors: Taiyab Abu , Islam Nazmun , Rahman Mokhlesur
Published: September 2022

The use of thin clayey soil as a liner plays an important role in many geotechnical and geo-environmental engineering applications, such as open channel and reservoir sealant, contaminant barrier etc. Their functional performance and sustainability depend primarily on the desiccation characteristics of these liners and barriers. A number of studies have been undertaken to quantify the degree of improvement achieved by using natural and synthetic fiber reinforcement. However, there is a lack of studies to understand the desiccation behavior of reinforced clay. This study aimed to explore the desiccation and cracking behavior of clayey soil reinforced with two natural fibers (coir and jute fiber) in addition to the degree of improvement in tensile strength. A series of direct tension and desiccation cracking tests have been conducted in the laboratory on clay-coir and clay-jute fiber mixes. The results demonstrate that when coir and jute fibers are used, the tensile strength of fiber-reinforced soil rises by up to 475 percent and 215 percent, respectively, when compared with the tensile strength of unreinforced soil at the same moisture content. Desiccation test results also show that blending of fibers reduces the breadth and depth of cracks significantly. The characteristics of unreinforced and fiber-reinforced clayey soil under desiccation and direct tension are briefly discussed in this paper. Findings of the present study will be important for professionals dealing with clay liners and trying to reduce cracking problems associated with drying soil.

Homework in Russian: trajectories of updating
Authors: Uskova I. V.
Published: September 2022

The paper is relevant as it highlights the problem of changing approaches to designing homework in the Russian language assigned in middle school. The research considers the modern requirements for teaching fixed in the legal documents that are in force in the Russian Federation. The purpose of the study is to show the directions of Russian homework updating in middle school. Such changes can improve the quality of studying Russian and the level of schoolchildren’s educational motivation. The research employed scientific and methodological literature analysis, a survey of the parties involved in the education relations, and an interview with them. Additionally, the study relied on monitoring how homework was organised by Russian language teachers and completed by students, examining homework results, and analysing pedagogical documentation in conjunction with self-reflection on my own pedagogical activity. The study resulted in identifying five main areas for updating learners’ homework in Russian. These include changing the goal setting of homework, approaches to selecting its content, promoting the individualisation and differentiation of both homework in general and homework assignments in its composition, changing the wording of homework and approaches to checking it. The paper concludes that homework is the most important teaching method that improves the quality of schoolchildren’s mastering the Russian language. In addition, the study highlights teachers’ crucial role in homework design, implementation, and support.

Some researches inform on trimetilglycine positive effect on poultry growth and meat quality in heat stress conditions. However little attention is paid to amino acid content changes in muscles. “BetaFeed” BAA (betaine) with 32% of trimetilglycine has been introduced to broiler diet to study trimetiglycine effect on broiler meat amino acid composition and taste qualities. 50% of methionine has been replaced with betaine in 2 experimental group and 50% methionine and 50% choline chloride has been replaced in 3 group. The best result has been reached in complex trait (index of broiler growing) for 3 experimental group when replacing 50% methionine and 50% choline chloride with betaine. Difference with control is 76 units. However difference between control groups is little – 7 units only. Difference between experimental and control groups in essential amino acids quantity is 0.58 to 0.70%. Analogic results have been received for non-essential amino acids.

The influence of the level of estradiol in the blood serum on the concentration of vitellogenin in Pushkin chickens at the end of the ovulatory cycle was studied. The results of the experiment show that in the studied chickens, the peak concentration of estradiol falls on the time interval between 7,5 and 2,5 h before egg laying (221,3±14,5 – 230,6±16,4 pg/ml, p<0,05) with subsequent its decrease (167,4±15,6 pg/ml). High correlation between the concentrations of estradiol and vitellogenin in the periods 9 h 00 min – 7 h 30 min and 2 h 29 min – 0 h 15 min before egg laying (r = +0,94 …+0,98, p<0,001), and also a significant relationship of estradiol with the weight of the yolk (r = +0,50 …+0,72), indicate that in these periods, the concentration of estradiol can predict the content of vitellogenin in the blood of chickens and the weight of the egg yolk. Accordingly, the concentration of estradiol can be used as a criterion for the selection of chickens on the basis of yolk size.

Published: September 2022

Small and Medium Enterprises (SMEs) are the main drivers of the economy in developing countries, one of which is Indonesia. Several SMEs still need to be developed in Indonesia, especially for the 3T region (lagging, leading, and outermost). Sumbawa is one of these areas. The majority of SMEs in the Sumbawa area are weaving SMEs. Weaving SMEs in this region still have problems in terms of SME competitiveness, innovation, and SME creativity. Therefore, they have not been able to compete with SMEs outside the 3T area. Thus, the importance of competitive strategy and knowledge management can encourage the management of information into knowledge that can be used for strategic decision-making, especially the competitive strategy of SMEs. This study will examine the application of knowledge management to SMEs in Sumbawa and whether the applied knowledge management can encourage the creation of a competitive strategy for Sumbawa SMEs. The research was conducted by census/saturated sampling to produce accurate results. The results show that the application of knowledge management in Sumbawa SMEs is proven to influence SMEs' competitive strategy. The study also contributes to new research on the role of organizational design that can affect knowledge management's influence on competitive strategy.

The dependences of the oxygen solubility on the contents of cobalt and zirconium in the studied melts were calculated. Zirconium contents in minimum points on the oxygen solubility curves and the corresponding minimum oxygen concentrations were determined.
Soberanía Popular y Sujetos Políticos Emergentes: Reflexiones Desde el Perú del Siglo XXI
Authors: Ilizarbe Pizarro Carmen
Published: September 2022

Este artículo discute la preponderancia que han alcanzado la idea y el ejercicio de la soberanía popular en la política peruana del siglo XXI, en un contexto marcado por la crisis de la democracia representativa inaugurada en 1980 y reinstituida –en clave neoliberal– en el año 2000. El argumento central es que un conjunto de expresiones de soberanía popular emerge para expresar, desde el espacio público e informal de la calle, un cúmulo de demandas sociales desatendidas por el Estado e inadecuadamente canalizadas por el sistema de representación política. Se revela la existencia de una pluralidad de sujetos sociales politizados, cuya diversidad expresa el carácter pluricultural y desigual de la sociedad nacional, pero constituye también un límite importante para la articulación de proyectos políticos de mayor envergadura.

Ruşen Keleş’in ‘Eski Ankara’ olarak tabir ettiği kentsel çekirdekte tam 52 yıl önce yaptığı saha çalışmasının sosyo-ekonomik yönden benzerini gerçekleştirme hedefini taşıyan bu araştırmada, Kale, Sakarya ve Anafartalar Mahallelerinin mevcut sosyo-ekonomik yapısı hakkında güncel bilgi sağlanmakta ve Keleş (1971)’in Eski Ankara’da Bir Şehir Tipolojisi isimli eserinde sunulan bulgular ile bugünkü bulgular karşılaştırmalı olarak analiz edilmektedir. Eski Ankara’da yaşayan hanelerin sosyal ve iktisadi özelliklerindeki değişim 1970’te hane temsilcilerine sorulan soruların 2022’te tekrar yöneltilmesi ile izlenmiştir. Keleş Ankara’nın tarihi kent merkezinin çöküntüleştiği ve bir geçiş bölgesi niteliğinde olduğu yönündeki tespitlerinin yanı sıra Batı’nın sefalet bölgelerinden farklı olarak mahalle kültürünün ve sosyo-kültürel bağların da yaşamaya devam ettiğini söylemiş ve bölgeyi tanımlamak için “yerli slum” ifadesini kullanmıştır. Sonraki yıllarda yapılan başka çalışmalar çöküntüleşmenin gerçekleşmediği yönünde bulgular sunmuş olsa da kentsel yenileme, soylulaştırma, neoliberalleşme eksenindeki müdahaleler sonucunda Keleş (1971)’in öngörüsünün gerçekleştiği ve Eski Ankara’nın “yerli slum” özelliğinin pekiştiği anlaşılmaktadır. Çalışmada bu sonucu destekleyen süreklilikler ve kopuşlar tespit edilmiştir.

Experiencing war arouses feelings of injustice, which in turn can activate angry feelings toward God. The purpose of the present study was to assess the relationship between anger toward God, faith maturity, interpersonal decision-making, forgiveness, psychological well-being and spiritual well-being among war refugees from Ukraine who arrived in Poland and Germany. Data from paper-and-pencil surveys were collected from 243 religious people aged 18–68 years, 82% of whom were women. Structural equation modeling (SEM) showed that anger toward God is a negative predictor of faith maturity, forgiveness and well-being (including a psychological and spiritual component as a second-order variable). In addition, positive relationships were observed between faith maturity, forgiveness and well-being. Finally, faith maturity and forgiveness serially (and forgiveness also as a simple mediator) mediated the relationship of anger toward God and well-being. The results help to explain why people who feel anger toward God are still able to experience well-being, suggesting that faith maturity may inhibit angry feelings toward God through more frequent decisions to forgive abusers.
Stability and Change in Dispositional Envy: Longitudinal Evidence on Envy as a Stable Trait
Authors: Erz Elina , Rentzsch Katrin
Published: September 2022

Dispositional envy has been conceptualized as an emotional trait that varies across comparison domains (e.g., attraction, competence, wealth). Despite its prevalence and potentially detrimental effects, little is known about stability and change in dispositional envy across time due to a lack of longitudinal data. The goal of the present research was to close this gap by investigating stability and developmental change in dispositional envy over time. In a preregistered longitudinal study across 6 years, we analyzed data from N = 1,229 German participants (n = 510-634 per wave) with a mean age of 47.0 years at intake (SD = 12.4, range 18 to 88). Results from latent factor models revealed that both global and domain-specific dispositional envy were stable across 6 years in terms of their rank order and mean levels, with stability coefficients similar to those of other trait measures reported in literature. Moreover, a substantial amount of variance in global and domain-specific dispositional envy was accounted for by a stable trait factor. Results thus provide evidence for a stable disposition toward the experience of envy both at the global level and within specific envy domains. The present findings have important theoretical and practical implications for the stability and development of dispositional envy in adulthood and advance the understanding of emotional traits in general.
From Lung to Brain - Respiration Modulates Neural and Mental Activity
Authors: Goheen Josh , Anderson John A E , Zhang Jianfeng , Northoff Georg
Published: September 2022

Respiration sustains metabolic activity in all organs, including the brain. Respiration protocols have been developed to manipulate mental states, including their use for therapeutic purposes, e.g., in anxiety disorders. In this systematic review, we discuss evidence that respiration may play a fundamental role in the coordination of neural activity, behavior, and emotion. The main findings are: (i) respiration affects the neural activity of a widespread variety of regions in the a brain; (in) respiration modulates different frequency ranges in the brain's dynamics; (iii) different respiration protocols (spontaneous, hyperventilation, slow or resonance respiration) yield different neural and mental effects; (iv) the effects of respiration on the brain are related to concurrent modulation of biochemical (oxygen delivery, pH) and physiological (cerebral blood flow, heart rate variability) variables. We conclude that respiration may be an integral rhythm of the brain's neural activity. This provides intimate connection of respiration with neuro-mental features like emotion. A respiratory-neuro-mental connection, in turn, holds the promise for a brain-based therapeutic usage of respiration in mental disorders.
Can Bureaucrats Break Trust? Testing Cultural and Institutional Theories of Trust with Chinese Panel Data

Published: September 2022

What is the relationship between trust and the quality of political institutions in a society? According to an influential cultural perspective, social trust—the belief that most people can be trusted—is a value inculcated during individuals’ formative years, and remains fixed afterwards. A second perspective holds that social trust reflects experiences throughout the life course, particularly interactions with public institutions and officials. We test these cultural and institutional theories using data from three waves of the Chinese Family Panel Studies, assessing how political and social trust respond to treatment by public officials that respondents consider unfair. We find such experiences, which we show in many cases likely meant being a victim of corruption, are associated with declines in trust. Yet the effects are short-lived: within two years both types of trust revert to their original levels. Our results therefore provide mixed support for both theories, and suggest a reconciliation between them.
The Political Image of Left-wing Leaders in Poland: How Young Voters Evaluate the Politicians from Different “Political Generations”
Authors: Marmola Maciej , Darmoń Krzysztof
Published: September 2022

In recent decades political activity has become more and more personalized. Thus, to achieve political success, it is necessary to have a recognizable and popular party leader. Polish left-wing parties have adopted a different strategy. Instead of betting on one leader, they promote “three tenors” from different political generations (Robert Biedroń, Włodzimierz Czarzasty, and Adrian Zandberg). The aim of our study (N=379) is to diagnose how voters perceive the political images of these left-wing leaders and what feelings they have towards them. We confirm the findings from other studies suggesting the effect of political preferences and ideological orientation on the perception of political image and emotional attitudes to party leaders.

Published: September 2022

Este estudo teve como objetivo avaliar a dinâmica da decomposição da fração foliar de Gliricidia sepium em diferentes sistemas de uso e manejo do solo. A pesquisa foi desenvolvida em três sistemas de uso da terra: sistema agroflorestal (SAF), mandala e pastagem. O método empregado para quantificar a decomposição da fitomassa foliar foi o de bolsas de nylon “litter bags”, coletadas a cada sete dias, por um período de 56 dias. Foram avaliados a massa remanescente (g), constante da decomposição (k) e o tempo de meia-vida (T½) do material foliar. O delineamento estatístico utilizado foi o inteiramente casualizado seguindo o esquema fatorial 3 × 8 (sistemas × períodos), com três repetições. Verificou-se efeito significativo isolado apenas para os períodos de avaliação. A taxa de decomposição variou entre 0,0087 e 0,0041 g g-1 dia e o T½ em 79 e 165 dias, uma vez que a curva de decomposição indicou que a perda da fitomassa foliar nos primeiros 20 dias de avaliação foi relativamente estável entre os sistemas. A taxa de decomposição e o tempo de meia-vida do material foliar foram mais expressivos no solo sob SAF.

Decomposition of Gliricidia sepium phytomass in different land occupation systems
 
ABSTRACT: This study aimed to evaluate the dynamics of the decomposition of the leaf fraction of Gliricidia sepium in different land use and management systems. The research was developed in three land use systems: agroforestry system (AFS), mandala and pasture. The method used to quantify the decomposition of leaf phytomass was nylon bags “litter bags”, collected every seven days, for a period of 56 days. The remaining mass (g), constant of the decomposition (k) and the half-life (T½) of the leaf material were taken. The statistical design used was the randomized integer following the factorial scheme 3 × 8 (systems × periods), with three replications. There was a significant isolated effect only for the evaluation periods. The decomposition rate varied between 0.0087 and 0.0041 g g-1 day and the T½ in 79 and 165 days, since the decomposition curve indicated that the loss of leaf phytomass in the first 20 days of evaluation was relatively between systems. The decomposition rate and the half-life of the leaf material were more expressive in the soil under AFS.

The use of a two-frequency eddy current method for measuring the electrically conductive wall thickness under significant variations in the test parameter and the lift-off
Authors: Goldshteyn A.E. , Abakumov Kh.Kh.
Published: September 2022

The paper addresses the problem of eddy current testing of the wall thickness of light-alloy drill pipes under significant variations in both the test and the influence parameter of the test object – the lift-off between the eddy current probe and the test object surface. The performance of the two-frequency eddy current method is shown through the use of the signal of the surface eddy current probe of the added high-frequency voltage amplitude as an informative parameter to measure the lift-off and the phase of the added low-frequency voltage. Experimentally obtained dependences of the informative parameters on test and influence parameters are presented. The phase and amplitude-phase multi-parameter methods used to suppress the effect of stray parameters in eddy current testing are analyzed; the effectiveness of their application under significant variations in test and other influence parameters of the test object is shown to be limited. The effectiveness of nonlinear functions for the inverse transformation of the informative parameter into the test parameter to suppress the lift-off effect on test results is estimated. Criteria of choice for informative parameters of the eddy current probe signal are considered. The measurement error caused by the approximation error of the nonlinear functions of the inverse transformation of the informative parameters into the test parameter within the variation ranges of the test and influence parameters is estimated.
