Imagens que educam: Cultura visual e modos de endereçamento na revista Junior (2007-2015)
Authors: França Filipe Gabriel Ribeiro
Published: February 2021

Este artigo problematiza as imagens corporais que foram publicadas na revista Junior (2007-2015) durante o seu período de circulação no Brasil. Inicialmente são abordadas as imagens corporais na revista, fazendo uma articulação com o campo da cultura visual. Em seguida é problematizada a questão das imagens do corpo de classe média endereçadas aos leitores, dialogando, sobretudo, com a teoria dos modos de endereçamento estudada por Elisabeth Ellsworth (2001). Para tanto, a revista foi explorada enquanto um documento em que foram analisadas as 66 edições publicadas, tendo como foco de investigação as imagens que diziam dos modos de ser homem, jovem e homossexual. A partir de tal pesquisa foi possível problematizar a potencialidade das imagens na revista Junior e o seu caráter educativo, levando-nos a pensar nos usos que fazemos das imagens, como elas nos afetam e subjetivam, de que forma entram em nossas vidas e como nos relacionamos com elas.

Chemical parameters of gourmet salts compared withsalt extracted from eichhornia crassipes evaluated by energy-dispersive x-ray spectrometry
Authors: Rossignoli Paulo Afonso , Silva Frederico Fonseca da , Peternella Wilson Sacchi
Published: February 2021

Salts have been part of human nutrition since 2,000 b.C., having originated in the Zhongba region, in China. Itssubstantial availability in food markets and stores specialized in condiments led us, curiously, to compare its elemental chemical composition with that of salt extracted from a floating aquatic macrophyte, known commonly as “water hyacinth” (Eichhornia crassipes), whose product, after extraction from dry matter, was popularly denominated“indigenous salt”. The objective of the present study was to evaluate the chemical composition of gourmet salts in comparison with indigenous salt using the energy-dispersive X-ray spectrometry (EDX) technique. Eichhornia crassipes exhibited higher concentrations of chloride (35.834%), potassium (62.146%), sulfur (1.095%), calcium (0.450%), bromine (0.177%), silicon (0.124%), copper (0.029%), magnesium (0.123%), and rubidium (0.023%) than the gourmet salts. Our results indicate that this indigenous salt should be consumed under medical guidance due to its high concentration of potassium chloride, a salt whose properties are used for specific human treatment and not daily consumption.

Published: February 2021

The objective was to map spatially and temporally the degradation of the lands of the Sucuru River basin in the region of Cariri Paraibano. The SPRING 5.2.7 program was used for the digital processing of orbital images and the photointerpretative keys for evaluation of levels of degradation, field visits, consultations with literature and public agencies. There was a regeneration of the areas that previously were in the levels of degradation very serious and moderate severe, due to factors such as the drought that is hindering the agricultural exploration, as well as the reduction of the animal exploitation and of the arboreal extractivism. The banks of the water bodies of the basin, for the most part, are at the level of severe degradation, resulting from the removal of this vegetation due to the exploitation of these areas for the most varied uses. The degradation processes, together with the incorrect use of the lands of the studied basin had as main consequence, the rural exodus, requiring the intervention of the public power so that the local communities can develop sustainable activities, considering social, economic and environmental aspects.
Estudo de padrões de clusters surgidos em uma dinâmica de perseguição e fuga

Published: February 2021

An agent-based stochastic model was developed with the objective of studying the movement and formation of clusters in systems composed of prey and predators. A discrete virtual network was created, where two types of agents can move in, one of them moving like prey and it is programmed to move away from the second type, which behaves like a predator. In this model, as the main interest was to study the patterns formed by the dynamics of persecution, the proportions of these agents are kept fixed in each simulation. The rules of movement are based on an asymmetric random walk, which causes the two types of agents, with their respective behaviors, to perform a Brownian motion when far apart. However, the dynamics of persecution begin to get more intense as these two approaches. To analyze the conditions in which the clusters emerge, the concentrations of the two types of agents were varied and a parameter σ, which acts as a mediator, amplifying or attenuating the "forces" of attraction/repulsion between the individuals. The simulations revealed patterns of randomly positioned agents in the network, as well as the counting of the average number of clusters over time.

Published: February 2021

Sugar production and exportation are important factors for the Brazilian economy, because Brazil produces the largest amount of sugar and accounts for almost half of the world´s sugar exports. This research aimed to monitor the sugar export from January 2000 to April 2019, by means of residual control charts with pretreatment of autoregressive integrated moving average (ARIMA) models. The data used in the study were collected from the Portal Única website. We opted for the application of ARIMA modeling because the data was not stationarity and presented autocorrelated values. The best model to predict the Brazilian sugar exports was SARIMA (1,1,1)(1,0,1)6 due to the seasonal behavior of the series, which may be related to the sugarcane planting and harvesting period. It was possible to observe the presence of upper-limit outliers in the residual control chart, in October 2012 and February 2016, which characterize a sugar exports higher than forecasted exports.

Published: February 2021

This tutorial aims to analyze nonlinear models of Smooth Transition Regression with JMulTi and contribute to the understanding of STR specification, from the estimation until the evaluation cycle of these models. It provides pedagogical explanations, combining theoretical concepts and empirical results coherently. Especially in economic relationships, where an asymmetric behaviour with distinct effects is often found on contractions and expansions. As economic series generally present asymmetric/nonlinear behaviour, Smooth Transition Regression (STR) models provide a flexible empirical strategy that allows capturing the impacts of possible types of asymmetry in the data, Souza (2016).An overview of theory and applications in software is described. These nonlinear models describe in-sample movements of the stock returns series better than the corresponding linear model. The data used in this study consist of daily prices index from January 02, 1995 to March 29, 2013, a total of 4761 observations, from Germany (DAX30). The data was collected from the DataStream database considering 5 days a week. The data (price index) is converted to base 100 and the yields are then calculated based on the first differences in the log price series. 10-year interest rates treasury bond regarding the same markets identified has also been collected for the same period.

Understanding how particular regions behave and / or resemble socioeconomic aspects can contribute to regional development. Thus, this paper aims to identify similarities of socio-spatial behavior existing among the municipalities of the state of Rio Grande do Sul, based on census data, and to evaluate the changes that have occurred over the years. For this, a cluster analysis of the municipalities was performed before some indicators. With the clusters  was verified the existence of difference in the behavior between the groups through non-parametric tests and thematic maps were created that bring the behavior of the regions in a spatial way. Five clusters of municipalities were detected in 1991 and four clusters in the years 2000 and 2010. It is also noticeable the socio-spatial development over the years. However in 2010 is when the greatest evolution occurs for most municipalities. From the generated clusters it is possible to outline public policy strategies and further prioritize the measures that should be taken by the competent bodies in each of the regions studied.

Background: The Emotion Recognition Index (ERI) is a psychometric tool develop to evaluate emotional perception. Its items were selected using Classical Tests Theory. Objectives and Methods: Evaluate ERI items performance under current psychometric theories, using Item Response Theory (IRT) thought a two parameter logistic model. Results: 12 items were removed from the Face Module to fulfill the unidimensionality assumption. 20 items were eliminated from the Voice Module because they presented low discrimination values. Both modules presented information curves peaks among low latent trait values. Discussion: Findings suggest ERI is mostly composed of low difficulty items. ERI is best used to evaluate individuals with low emotional perception. Authors suggest further studies should use IRT to select items for instruments evaluating emotional perception.

The aim of this paper is to present the analysis carried out on the impact of CCNE's “Central de Tutoria” on the development of UFSM students' learning, especially on the aprovation indexes. Data were collected from May to June 2019, with 752 attendances during this period in 367 students from 47 different courses at 6 teaching centers. It was found that in all the most sought after subjects in the "Central de Tutoria", the number of students approved was higher than those who failed, with a greater emphasis on the General Statistics discipline with an 88% pass rate. Overall, it was observed that the students who sought support are mostly in the first stages of the various courses. This data reinforces the objectives of the creation of the "Central de Tutoria", since it is in the early stages of the courses that the failure rate is high, contributing to dropout. In sum, student demand for this support is expected to increase and, based on the results of the data analysis presented in this work, it is believed that continuing the "Central de Tutoria" will positively contribute to the permanence rates as well as the success of our students.

The objective of this study was to evaluate the presence and severity of musculoskeletal (MS) symptoms in the trunk and upper limbs of keyboardists. Cross-sectional study, including volunteers of both genders, aged 18-40 years, who practiced for at least 2 years, excluding those with systemic diseases, were assessed for MS pain using the Nordic Musculoskeletal Questionnaire. The χ-squared test was used for statistical analysis and a significance level of 5% was adopted. This study was approved by the Ethics Committee of the Ceuma University (opinion nº 2,627,609). Thirty-nine volunteers were evaluated, and all reported experiencing pain or discomfort. The regions of greatest complaint of chronic pain/discomfort were the thoracic and lumbar spine (n = 27 ,69.24%; p 0.05) and wrist/hand (n = 23.58.9%). The highest acute complaint was in the lumbar spine (n = 12, 30.76%; p 0.05), and in the wrist/hand (n = 9, 23.07%). A severity index of 1 was the most frequent (n = 14, 36%). It can be concluded that keyboardists have MS mainly in the spine, wrist, and hands, although the severity of the symptoms is mild; the high frequency of complaints suggests the importance of prevention and treatment of musculoskeletal symptoms before aggravation.

The Master in environment holds annually the Environment Forum of the State of Maranhão. In 2019, the third edition of the event was held with the theme: Water Resources Management in Maranhão - Potentialities and Weaknesses for a Participatory and Decentralized Management, which presented 149 scientific papers divided into two distinct areas 82 works in the area of planning and environmental quality and 67 works in the área of health and environment. Due to the importance that the event has been showing to the State and the high scientific quality of the presented works, it was considered pertinent a wider dissemination, where all the scientific community would have access to the accomplished works, hence the idea of a Special Edition in a renowned Scientific Journal. Thus, to compose the special edition of the III Forum on the Environment, 15 articles were selected, which later underwent an “ad hoc” peer review to ensure quality. The articles have varied themes and range from environmental monitoring using georeferencing technologies, going through proposals of intervention methodology for environment recovery to articles focused on the influence of anthropic and environmental factors on human health.

Published: February 2021

In this work we will investigate the generating matrices for the positive integers of the Leonardo sequence, as well as some inherent properties of these matrices. In order to perform the process of generalizing the matrix form of Leonardo’s numbers, the extension to the field of non-positive integers is performed, in which the study of these matrices is unpublished in this research. The matrix form relates the matrices to the Leonardo numbers, and by raising these matrices to nth power, we obtain some new relations of this sequence, thus knowing their respective terms.

Authors: Muller Iuri Hermes , Carlos Eduardo Silva , Loreto Aline Brum , Soubhia Ana Luisa , Picoloto Camila Becker
Published: February 2021

Several Engineering problems can be modeled from differential equations, analytical and numerical methods can be employed to determine the solutions. Among these problems, applied in the area of Mechanics, there are those that involve the analysis of vibratory systems. The present work aims to conduct a study on the solutions of the second order ordinary differential equations that model these vibratory systems, seeking to solve these equations analytically from the application of different external forces. In order to solve analytically each of the equations that describe these systems, the homogeneous equation solution is first determined. Then, depending on the type of external force that acts on the system, the particular solution is obtained using the methods of Indeterminate Coefficients or Parameter Variation. The general solution is then obtained from the linear combination of homogeneous and the particular solutions. The analysis of the solutions shows that the displacements of the masses according to time, depending on the external force applied in the system, present varied behaviors among themselves. Over time, the homogeneous solution, characterized as transient response, becomes negligible, remaining only the particular solution, characterized as the permanent response.

The objectives of this work were to evaluate the method of thermotherapy via dry heat for the treatment of safflower (Carthamus tinctorius L.) seeds and, to verify its effect on the physiological and sanitary quality of seeds. The experiment was conducted in entirely randomized design, arranged in 5x6+1 factorial scheme, with six levels of temperature: 35, 45, 55, 65, 75 and 85 ºC and with five time periods: 24, 48, 72, 96 and 120 h, plus the additional treatment (control), with eight repetitions. The seeds were packaged in Kraft paper bags and submitted to the forced circulation greenhouse according to the factorial mentioned above. We evaluated the physiological and sanitary qualities by the standard tests of germination, length and mass of seedlings, emergence at field and sanity. We observed that the thermotherapy can be used as treatment of safflower seeds, and it is efficient in the control of phytopathogens, without damage to the physiological quality up to 45 ºC, and the combination of 45 ºC 24 h-1 provided better phytosanitary quality for these seeds, increasing their germinative potential and emergence at field.
“A Química é uma área experimental!”: discursos sobre a experimentação em um curso de formação de professores de Química
Authors: Frozza Edson , PastorizaI Bruno Dos Santos
Published: February 2021

This study aimed to understand circulation of discourses that mobilize a conception about the relationship between Chemistry and experimentation in a Chemistry Degree course, assuming its role as a supervisor of practices and seeking to problematize its effects on teacher education and Basic Education. Theoretical and methodological bases of Discourse Analysis were used in the process of research, analysis and construction of the text. The analysis points to emergence of discourses based on a conception that Chemistry is essentially an experimental area and that produces and reproduces practices, whether in production of chemical knowledge, or in teaching and learning processes, which are fundamentally based on achievement of experiments. In relation to teaching, this conception runs through ideas which are possible to problematize, such as that of experiment itself is enough for learning and that Chemistry is learned by doing. The results presented in this work show the importance of rethinking practices that are naturalized in the chemistry teacher training courses.

Published: February 2021

The construction industry is responsible for a high consumption of natural resources, demanding high quantities of aggregate materials for use in construction. In addition, large quantities of rubber waste generated worldwide have emphasized the need to find practical reuse applications. The present study partially replaces fine aggregates by ash from a co-processing of milled and burned conveyor belt rubber waste. Test specimens with ash concentrations of 0%, 5%, 10%, 15% and 20%, were made comparing its workability, mechanical axial resistance and absorption of water by capillarity. It was concluded that the partial replacement of sand by 5% of rubber ash has improved the traditional concrete mixture, with better workability, less amount of water, leading to a greater resistance to axial compressive and acceptable absorption of water. Thus, the results confirm that the concrete with incorporation of rubber ash is a potential alternative technology to achieve sustainable development in the construction industry.

Biogas generation potential from anaerobic digestion of “Ponkan” and “Montenegrin” Tangerine peel waste
Authors: Carvalho Rafael Vieira de , Abreu Thais Cristina Campos de , Romanel Celso
Published: February 2021

Due to the increase in human damage caused to the environment, there is a need for remediation measures and techniques to be applied in favor of a sustainable future for upcoming generations. One of the sectors that have potential in the use of low carbon economy stocks is agribusiness. In fact, part of agribusiness is fruit growing which is one of the sectors of greatest Brazilian economic prominence, with a wide variety of crops produced throughout the country and in different climates. In the food production chain, there are several post-harvest losses and the consequent generation of large amounts of waste. Anaerobic digestion presents itself as an excellent and promising option for the treatment of food waste, contributing to the fight against the increase of polluting emissions and generating biogas for use as thermal or electric energy or even as a fuel to replace fossil fuels. The anaerobic digestion of organic waste is a biological process characterized by the absence of oxygen which through the metabolic activities of microorganisms causes the complex organic material to be converted mainly into methane and carbon dioxide. In a scenario where the production of waste around the world is growing more and more, efficient waste treatment techniques are essential to ensure lower greenhouse gas emissions in the environment. In this study, the biodegradation capacity of the substrate formed with “ponkan” and “montenegrin” tangerine peels was investigated through BMP (Biochemical Methane Potential) tests with the determination of water content, total solids, and volatile solids in samples of laboratory under ideal conditions of pH, temperature, and humidity. The tests were carried out over a period of twenty-one days, having been found, in general, a greater production of gas until the twelfth day of testing, with a gradual reduction until stabilization around the twentieth day. The results obtained in laboratory show that there is a positive potential in the generation of biogas using tangerine peels in relation to the peels of other fruits researched in the literature (orange, banana, among others), with a biogas generation potential of 615.38 NmL/gSV for “ponkan” tangerine peel and 565.84 NmL/gSV for “montenegrin” tangerine peel. Brazil, due to its vast territorial extension and favorable climatic conditions, stands out in the international agricultural market and, therefore, holds great potential in the scenario of energy change. Despite the high potential of waste generated in the country, technologies for recovering organic matter are still incipient and even unknown. The results of this research are yet another contribution to reaffirm and publicize the benefits of treating organic matter via anaerobic digestion, with significant economic, social, and environmental advantages.
Normalized difference vegetation index analysis of the first part impacted with the breaking of the Fundão Dam in Mariana-MG

Published: February 2021

This paper addresses the exploitation of mineral resources and suggests that an environmental management that meets a set of measures and mutual cooperation between public and private managers, civil society, and mining companies that exploit natural, renewable, and non-renewable resources is needed. Cooperation between managers and joint safety measures can prevent present and future accidents like the one that occurred in Mariana City in Minas Gerais State (MG). The questioning presented puts into discussion the disaster that occurred in Mariana City due to the rupture of the ore tailings dam (Fundão dam) in November 2015. With an estimated population of 60,000 inhabitants, Mariana City has a local economy directly linked to mining activities. Due to the impact caused by the rupture of the Fundão dam, both city and vegetation were destroyed, among other factors observed along the path followed by the tailings. However, what is discussed in this article with greater emphasis is the loss of vegetation in the watershed. The methodology compared the degree of vegetation coverage in the basin area through the analysis of the Normalized Difference Vegetation Index – NDVI for 2013, 2016, 2017, 2018, and 2019 in different months. Some images refer to August and other samples are from September, complementing the process through the use of Landsat 8 satellite images - OLI sensor, acquired from the United States Geological Survey (USGS) repository. 299 points were distributed in the quadrant to perform the analyses (n = 299). The level of significance was set at 5% with a 95% confidence, to ascertain and verify whether the data distribution is in an acceptable condition (dense or semi-dense vegetation cover). Regarding vegetation analysis, the Kolmogorov-Smirnov and Shapiro-Wilk tests were used. Both tests indicated a non-normal distribution for the NDVI data set, which indicates the absence of a vegetation index that was covered by the tailings, resulting in an area with large spaces without the coverage previously registered in 2013. We conclude that the vegetation suffered a drastic alteration provoked by the rupture of the Fundão dam which also led to homeless residents, negative impacts on the livelihood of the small farmers and fishermen, silting up of rivers and streams, death of several animal and plant species, and also affected the ecosystem and the local and regional biodiversity.

The presence of natural organic matter (NOM) in water does not present direct risk to the human body or to the environment. However, its presence along with other pollutants can lead to countless issues and damage human health and the environment. The hydrodynamic cavitation (HC) phenomenon started being used in the early 21st century as a process capable of treating supply-water and wastewater based on pollutant and pathogen degradation. Process effectiveness increases when it is combined to chemical agents, creating an advanced oxidation process (AOP). Although several studies have presented broaden applications for the HC process, its use for NOM removal from supply-water was not yet assessed; therefore, it remains a gap in scientific knowledge. The aim of the current study is to assess HC potential in NOM removal. In order to do so, the experiments were carried out in bench scale hydrodynamic cavitation system operated at batch model within 15-min duration period-of-time. In addition, decantation experiments (24-h period-of-time) were performed in order to check HC influence on molecules found in reaction medium after the exposure of NOM to the phenomenon. NOM was produced by a synthetic humic acid (HA) matrix at fixed concentration of 100 ppm. In total, 16 experiments were carried out; each experiment was featured by the following pair: pH (2.6, 3.0, 3.5 and 5.5) and hydrogen peroxide (0, 1, 5 and 30 mL). The best removal efficiencies (34%-36%) were observed in the most acidic pH ranges (2.6-3.0) at H2O2 concentration of 15mL. Results have presented high NOM removal efficiency (approximately 90%) after decantation at the most acidic pH ranges, as well. It can be explained by the fact that hydrodynamic cavitation in acid solution can break molecular structures suspended in the liquid medium, which favors decantation. Based on the present study, hydrodynamic cavitation with hydrogen peroxide addition can remove NOM from water; moreover, pH control is an essential factor for process development.

O artigo apresenta uma pesquisa bibliográfica acerca do Poder Simbólico (BOURDIEU, 2007), Relações Públicas (SIMÕES, 1995; GRUNIG, 2011) e Organizações (KUNSCH, 2003), ancorados pela perspectiva sistêmica (LUHMANN, 2002) e pelo paradigma da complexidade (MORIN, 2001), para correlacioná-los com a prática da disciplina “Comportamento Organizacional”, como uma possibilidade ao contexto das organizações. Entendemos que o uso de metodologias ativas emerge como uma possibilidade de buscar a pró-atividade dos alunos estimulando o seu engajamento com o tema proposto, assim, nos ancoramos na taxonomia de Bloom (ANDERSON et al., 2001) para explorar o processo de ensino e aprendizagem.

A amostra incluiu 189 empresas e a metodologia utilizada foi a análise de conteúdo baseada na presença e interação em redes sociais. Os resultados revelaram que as empresas brasileiras se comunicam de maneira semelhante às empresas globais. De modo geral, identifica-se que o uso do Facebook como uma ferramenta informativa com poucas estratégias para interação com os públicos.

Para se pensar e criar outros tipos de narrativas: territórios midiáticos e mídia tática para crianças, no contexto da favela da Providência
Authors: Barata Luiza Cunha
Published: February 2021

A falta de representatividade midiática e a proliferação de ferramentas tecnológicas nos contextos de grandes centros urbanos vêm motivando a construção de outros territórios midiáticos, para além da grande mídia. O objetivo deste artigo é tentar compreender como tais iniciativas podem se destinar a crianças imersas no contexto de disputa pelo espaço urbano.
CRIANÇAS E ADOLESCENTES: DOS DIREITOS FORMALMENTE RECONHECIDOS À INSUFICIÊNCIA DE SUA CONCRETIZAÇÃO E O CRESCENTE PROCESSO DE JUDICIALIZAÇÃO
Authors: Bressan Carla Rosane , Demétrio Antonia
Published: February 2021

O presente artigo busca refletir sobre o contexto contraditório de “direitos formalmente reconhecidos” e a insuficiência ou ausência de sua concretização via política pública. É nesse embate que tem crescido a busca de acesso aos direitos pela via da Justiça. Nesse ano de 2020, em que o Estatuto da Criança e Adolescente (ECA) completa 30 de promulgação, é fundamental pautar a presente discussão, uma vez que tem ocorrido o aumento dos processos de judicialização envolvendo as políticas sociais básicas, de modo especial no campo da criança e adolescente. Dessa forma, procura-se caracterizar a atenção à Educação Básica e à Saúde no âmbito das referidas políticas no Estado de Santa Catarina, levantando as principais faltas e/ou omissões da intervenção pública; e, como consequência, sinalizar o aumento de demandas que têm chegado ao Ministério Público Estadual (MP/SC), envolvendo essa área. Como resultado do estudo, verificou-se que entre 2014 e 2018 houve um aumento significativo no número de processos em tramitação no MP/SC envolvendo a atenção a crianças e adolescentes, sinalizando a ausência do Estado na oferta de políticas públicas universalizantes. Conclui-se ainda que, apesar de transcorridos trinta anos da promulgação do Estatuto, infelizmente crianças e adolescentes ainda continuam tendo seus direitos básicos violados.

SISTEMA SOCIOEDUCATIVO: FORTALECENDO A REDE DE APOIO FAMILIAR PARA O INGRESSO DO ADOLESCENTE NO CUMPRIMENTO DE MEDIDA SOCIOEDUCATIVA DE INTERNAÇÃO
Authors: De Matos Graciele Silva , Janczura Rosane
Published: February 2021

Este artigo é fruto do Trabalho de Conclusão de Curso em Serviço Social da Universidade Federal de Santa Maria descrito em 2015. O trabalho apresenta o período de estágio curricular em serviço social numa instituição de atendimento socioeducativo de internação para adolescentes em conflito com a lei, na região central do Rio Grande do Sul. Neste é realizada uma memória histórica do atendimento a criança e adolescente no Brasil dos tempos da colonização até a socioeducação. Na história o atendimento a adolescentes que cometiam algum delito era de forma punitiva, porém com o avanço do Sistema de Garantia de Direitos, a proteção e a responsabilização dos adolescentes possibilitaram o atendimento com base na dignidade humana e de sujeitos de direitos.  Desta forma, o Estatuto da Criança e do Adolescente (ECA) reformula o atendimento para adolescentes que cometeram o ato infracional, com a premissa da responsabilização a partir das medidas socioeducativas. Neste espaço sócio ocupacional, o assistente social encontra o desafio de garantir o direito do adolescente, este que se encontra em situação de desigualdade social e fragilizado por políticas públicas que não garantem a proteção integral de seus direitos sociais. Para o trabalho socioeducativo, de inserção e da garantia à dignidade no espaço de internação, a intervenção de estágio do serviço social neste espaço proporcionou o atendimento do adolescente e da sua família, fortalecendo-a e incluindo-a na proteção social básica de seu respectivo território.
AÇÕES DE DESTITUIÇÃO DO PODER FAMILIAR EM PROCESSOS DE ADOÇÃO NO RIO DE JANEIRO: VALORES MORAIS E PRÁTICAS LEGAIS.
Authors: Rinaldi Rinaldi Andrade
Published: February 2021

O objetivo do artigo é compreender como são conduzidas as “ações de destituição de poder familiar” (DPF) de crianças e jovens em processo de adoção. Interessa também analisar como são julgados esses processos quando as “genitoras” cumprem pena privativa de liberdade em instituições prisionais. Propomos análise comparativa em ações cujas mães de nascimento não são privadas de liberdade, buscando apreender se há alguma especificidade nas situações que envolvam mulheres presas e sua prole. Almejamos entender, a partir da análise de quarenta e nove processos, quais são os valores e saberes produzidos pela equipe técnica das Varas da Infância, da Juventude e do Idoso (psicólogos e assistentes sociais) em seus pareceres técnicos para convencer juízes sobre a viabilidade de uma DPF. Com o intuito de materializar esses objetivos, acreditamos que, apesar de haver variação de conteúdos nos “autos” coletados, a análise de três dessas ações nos possibilita inferir como diferentes práticas de justiça em âmbito da Infância e da Juventude estão organizadas. Acreditamos que há uma estreita relação entre pressupostos morais familiares, suportados nas relações de gêneros, assim como em concepções sobre garantias de direitos e em visões científicas sobre a pessoa nas práticas de justiça em questão.

Authors: Moraes Joysi , Mariano Sandra Regina Holanda , Dias Bruno Francisco Batista
Published: February 2021

Neste artigo apresenta-se os resultados da avaliação de um curso de formação em gestão para diretores de escolas públicas. Uma pesquisa analisou em que medida os egressos desenvolveram as competências de gestão necessária ao exercício do cargo, percebidas a partir das suas práticas de gestão na escola. Foi realizada uma pesquisa e utilização de análise fatorial nas 650 respostas válidas. Os resultados ratificam a literatura sobre os benefícios da formação em gestão. Entretanto, enquanto internacionalmente o uso de dados das avaliações é percebido como parte da gestão dos processos de ensino e aprendizagem, no Brasil os gestores das escolas públicas percebem as práticas relacionadas ao uso desses dados de avaliação como um processo a parte da gestão da escola.Palavras-chave: formação em gestão; gestor de escola pública; avaliação de eficácia; avaliação do domínio.

Política Internacional e o “Outro” Religioso: a Inerência do Laicismo no Orientalismo e o Caso do Irã
Authors: Wachholz Rafael de Oliveira , Maia Eduardo Lopes Cabral
Published: February 2021

O presente texto é composto de uma revisão bibliográfica voltada para a compreensão do papel da religião no discurso orientalista. Analisa-se, em um primeiro momento, como a relação entre Estado, sociedade e religião é atravessada por concepções normativas a respeito da secularização e da laicidade das sociedades modernas e como, na realidade, cada sociedade segue sua própria trajetória sócio-histórica em termos de como se relaciona com a religião. Em um segundo momento, evidencia-se como o componente religioso é utilizado no discurso orientalista para legitimar a política externa do Ocidente, principalmente dos Estados Unidos, para o Irã. Conclui-se que a religião e as dinâmicas a ela associadas é variável de fundamental importância para a compreensão da política internacional contemporânea.
