O Risco Hídrico em uma Coleção Didática do PNLD (2020-2024)
Authors: Silva Maysa Azani da , Rabelo Lacan , Silva Leandro Londero da , Dornfeld Carolina Buso
Published: June 2023

A água é um recurso natural essencial para todos os seres vivos, e, portanto, quando pensamos nesse tema no contexto escolar, devemos tratar com criticidade as diferentes maneiras de abordagem desse tema, bem como as práticas pedagógicas envolvidas e os materiais didáticos utilizados. Por isso, este trabalho teve como objetivo analisar as maneiras pelas quais as temáticas Recursos Hídricos e Água estão presentes em uma coleção de livros didáticos de Ciências da Natureza e suas Tecnologias, destinada a estudantes de Ensino Médio, contemplada pelo Programa Nacional do Livro Didático (PNLD) de 2021-2024. A análise foi realizada nos 6 volumes da coleção e para a categorização dos dados utilizamos a Análise de conteúdo de Bardin e a Teoria da Sociedade de Risco, descrita por Ulrich Beck. Como resultados obtivemos 5 categorias temáticas: Recursos hídricos relacionados a Condução de Eletricidade; Recursos hídricos como fonte de energia renovável; Recursos hídricos como vetor de doenças; Recursos hídricos, consumo e conscientização e Recursos hídricos e a poluição dos corpos d’água. Os dados sistematizados e analisados apresentam como um fator positivo o fato de se tratar o tema em todos os volumes da coleção selecionada. Entretanto, verificamos que nenhum dos volumes analisados abordou a importância da gestão pública e da população na conservação e fiscalização das condições dos recursos hídricos, e nem a bacia hidrográfica como unidade de gerenciamento, o que seria de suma importância para ampliar a visão de estudantes e transformá-los em cidadãos participativos e ativos.  

PALAVRAS-CHAVE: Água. Sociedade de risco. Livro didático.

Oficina como espaço de problematização do tema “Mudanças Climáticas” no ensino de Ciências e Biologia: uma revisão sistemática
Authors: Aubérico Adriene Jaqueline , Obara Ana Tiyomi
Published: June 2023

Desenvolvida no ensino de Ciências e Biologia, a oficina além de aproximar os estudantes à linguagem científica, possibilita criar condições para se problematizar questões e dilemas socioambientais presentes na vida contemporânea, promovendo, assim, uma visão crítica da realidade. Dentre as questões socioambientais mais preocupantes, pela sua abrangência global, destaca-se as “mudanças climáticas” em curso. Devido ao alto impacto social e ambiental do fenômeno, além do baixo destaque do tema entre as pesquisas de práticas de ensino no Brasil, o presente estudo objetiva investigar os trabalhos existentes sobre o uso das oficinas por professores de Ciências e Biologia para se trabalhar o tema “mudanças climáticas”, visando compreender como tal estratégia tem sido utilizada no espaço escolar. Para isso, foi realizada uma revisão sistemática do assunto, levantando as principais análises dissertadas em trabalhos e pesquisas acadêmicas no decorrer dos últimos 10 anos (de 2012 a 2022) nos Anais do Encontro Nacional de Pesquisas em Educação em Ciências (ENPEC). A partir das análises realizadas ao longo dos anais, é possível evidenciar a escassez de trabalhos relativos ao ensino para as Mudanças Climáticas, tendo como estratégia metodológica as oficinas. Por consequência, observa-se a necessidade de se fomentar o uso de oficinas, visando promover um ensino integrado e investigativo, com problematizações, debates e construções críticas sobre a temática mudanças climáticas pelos docentes e alunos da educação básica.
Agronegócio e transformações de práticas camponesas numa região do ecótono Cerrado-Caatinga, Sudoeste do Piauí
Authors: Sousa Thiago Batista de , Silva Andréa Leme da
Published: June 2023

As estratégias agroecológicas de resistência camponesa, suas interfaces com a agrobiodiversidade nas áreas de ecótono Caatinga-Cerrado afetadas pelo agronegócio, ainda são pouco estudadas. Dessa forma, o objetivo geral do estudo foi analisar as transformações no saber-fazer de práticas agroecológicas de camponeses/as da comunidade Feirinha, Redenção do Gurguéia no Piauí (PI) frente à expansão da fronteira agrícola do agronegócio (principalmente soja) no estado. A coleta de dados secundários sobre as séries históricas de áreas utilizadas na produção de commodities no Piauí incluiu dados da CONAB (2011-2021) e do censo agropecuário do Instituto Brasileiro de Geografia e Estatísticas (IBGE). A coleta de dados primários foi realizada a partir de observação participante e  dez entrevistas semiestruturadas com camponeses (6 homens, 5 mulheres) da comunidade Feirinha. Observamos uma expansão no avanço da fronteira agrícola: as áreas de cultivo da soja têm sido dobradas no estado, desde 2015, sem nenhum decréscimo anual. Este período coincide, na comunidade, com perdas de territórios comunais e cercamentos nas áreas de caatingas e chapadas, impactando a criação de gado e coleta de frutos do Cerrado. Identificamos que a utilização de barragens traz impactos para a pesca e a introdução de insumos e técnicas de manejos voltados para o agronegócio coincidem com perdas de variedades nas espécies cultivadas. Concluímos que as transformações de práticas humanas agroecológicas podem comprometer a sustentabilidade no ecótono cerrado-caatinga, uma vez a perda de variabilidade de manejos resulta em impactos na multifuncionalidade, nas interações e na segurança genética nos territórios/modos de vida desses camponeses.
Espiral de ervas e educação ambiental escolar sob a égide da permacultura
Authors: Bronzati Clair , Okimoto Fernando Sérgio
Published: June 2023

Este artigo trata da construção de uma espiral de ervas com alunos do quarto ano da Escola Municipal de Ensino Fundamental “Augusto de Campos”, em Pradópolis/SP, como um excelente instrumento de educação ambiental na aprendizagem de ervas medicinais fundamentado na Soberania Alimentar, Tecnologias Sociais e Bioconstrução dos espaços Escolares e Urbanos e na Permacultura. A espiral de ervas foi elaborada com a parceria dos alunos e colaboradores nos diversos processos de sua criação e, sendo uma Tecnologia Social, o intuito foi levar aos discentes e a comunidade escolar os conhecimentos necessários para a promoção de segurança e soberania alimentar, através da troca de experiências e práticas no contato com a terra, com a pretensão social de multiplicá-la no território municipal. É imperativo afirmar que a metodologia ativa empregada levou os educandos à compreensão de que não se deve brigar com a natureza ao manejá-la, mas que existe uma outra forma de convivência entre homem e natureza, muito mais harmoniosa e profícua para ambos. Os resultados levaram a conclusão de que a educação ambiental desenvolvida na escola de ensino fundamental (anos iniciais) é capaz de sensibilizar os alunos com relação às temáticas que envolvem os cuidados com o meio ambiente.

Estudo de toxicidade de efluente de laticínio através de análises citogenéticas de raízes de Allium cepa.
Authors: Cavilha Karina Gonçalves , Bione Nilton cesar Pires , Martins Kelly Geronazzo
Published: June 2023

Os impactos ambientais decorrentes da industrialização são fatos indiscutíveis. Das diferentes atividades, as que consomem grande quantidade de água nos processos produtivos acabam por produzir grandes quantidades de resíduos que se não forem corretamente tratados antes de serem eliminados, acarretarão grande prejuízo ao meio ambiente. A indústria de laticínios é um exemplo de atividade produtiva que produz grande quantidade de resíduos potencialmente poluidores, constituídos de gorduras, sólidos suspensos, nutrientes variados, detergentes, soluções ácidas e alcalinas. Com o objetivo de avaliar o nível de toxicidade do efluente de laticínio, o presente trabalho analisou o índice mitótico e frequência de anormalidades mitóticas em tecido meristemático de raízes de Allium cepa expostas ao efluente na sua forma bruta e diluída. As análises citológicas revelaram a presença de anormalidades mitóticas variadas e em todas as fases da mitose como erros de segregação cromossômica, aderência cromossômica, pontes cromossômicas em anáfases e telófases e formação de fragmentos e micronúcleos. Tais achados revelam o potencial clastogênico e aneugênico tanto no efluente bruto como nas diluições, o que reforça a importância de tratamento adequado do efluente antes de seu descarte no ambiente.
Национальная сеть научных журналов как система: проблемы до и после санкций
Authors: Семенов Евгений Васильевич
Published: June 2023

В статье проведен анализ проблем национальной сети научных журналов в России в досанкционное десятилетие и после введения санкций. Отмечены достижения, связанные с цифровой трансформацией редакционно-издательского процесса и освоением международных стандартов. Показаны негативные последствия односторонней ориентации публикационной активности на увеличение видимости и цитируемости в изданиях, входящих в международные наукометрические базы данных, включая фактическую утрату государством субъектности в управлении российской научной периодикой. Обоснованы предложения, касающиеся (1) выделения в научной политике самостоятельного направления развития национальной сети научных журналов как системы, (2) определения ответственного за развитие научной периодики органа управления и восстановления разнообразия форм самоорганизации научного сообщества, (3) ориентации национальной сети научных журналов на полноценное информационное обеспечение фронта научных исследований в стране.
Концепция «узкого коридора»: история и современность
Authors: Балацкий Евгений Всеволодович
Published: June 2023

Статья посвящена обсуждению книги Дарона Аджемоглу и Джеймса Робинсона «Узкий коридор», которая представляет собой своеобразное теоретическое обоснование примата демократических институтов в деле построения прогрессивного общества и государства всеобщего благосостояния. Помимо структурного представления концепции «узкого коридора» в статье уделено внимание логическим противоречиям внутри этой теории, которая не может объяснить сформулированный парадокс Цицерона, когда на определенном историческом этапе самая совершенная смешанная институциональная конфигурация государственного правления – республика – заменяется самой примитивной чистой формой – империей. Обсуждаются теоретические тезисы и современные исторические факты, которые игнорирует концепция «узкого коридора». Обосновывается, что анализируемая новая концепция является одной из последних попыток построения всеобъемлющих монокаузальных теорий.
Город технологичный или город «удобный»: урбанистические тенденции и их воплощение (на примере Москвы)
Authors: Стрельникова Анна Владимировна , Веригина Тамара Евгеньевна
Published: June 2023

В статье рассматриваются подходы к определению устойчивого развития городской среды, «умного города» и «удобного города». Данные концепции оказались востребованными в российской градостроительной деятельности, что привело, в частности, к появлению стратегий по формированию «умной» городской среды, внедрению новых цифровых технологий в городскую повседневную жизнь, актуализации формата комплексной застройки микрорайонов. Однако растущая доля подобных инфраструктурных решений не всегда делает жизнь горожан удобнее. Авторы анализируют содержательный разрыв между ожиданиями от развития «умных», «удобных», комфортных городов и фактическим направлением модернизации. На примере Москвы рассматриваются основные элементы концепций устойчивого урбанизма и «умного города», а также способы их внедрения. В ходе анализа общероссийских и московских стратегий устойчивого развития, «умного города» и различных городских проектов было установлено, что происходит сужение концепции «умного города» до технологически-цифровых показателей, отражающих количество новых объектов, но не всегда учитывающих качественные характеристики изменения городской среды. В результате наблюдается разрыв между представлениями о развитии цифрового города и о развитии мегаполиса, удобного для жизни. «Удобный город» в практической реализации рассматривается отдельно от «умного», и одна из важных компонент – субъективная оценка городской среды самими горожанами – упускается из виду. Отмечается, что данный перекос может искажать анализ результатов движения по направлению к «умному» и «удобному городу», появляется рассогласованность между «умными» и «удобными» параметрами городской жизни, а сама идея удобства города для жизни перестает быть очевидной и убедительной для самих горожан.
Рождаемость в России: кого и как стимулирует демографическая политика?
Authors: Колбина Екатерина Олеговна
Published: June 2023

В статье исследуется современная демографическая политика России с точки зрения ее  реальных, а не декларируемых интенций. На основе анализа исторического контекста демографического вопроса в России и существующих работ, фиксирующих инертность итоговой рождаемости к мерам социальной поддержки, выдвигается предположение, что пронаталистская семейная политика используется регулятором в качестве точки входа для перераспределения ресурсов в строительный сектор через финансовых операторов – банки. Показано, что другие мероприятия демографического пакета, не связанные с  покупкой жилья, на практике не реализуются из-за институциональной неприспособленности среды или являются скорее мерами социальной помощи малообеспеченным семьям, а не тактикой, способствующей повышению рождаемости. Де-юре демографическая политика разворачивается в де-факто неолиберальную: спрос на жилье стимулируется средствами материнского капитала и финансированием программ льготного кредитования, долговая нагрузка населения растет, при этом российские семьи в целом не меняют свою программу детности и не рожают в процессе ее реализации детей больше, чем предсказывает вектор демографического развития России.
Благополучие как показатель субъективной мобильности
Authors: Епихина Юлия Борисовна
Published: June 2023

В статье анализируется относительно новое исследовательское направление – изучение субъективной мобильности. Рассматриваются существующие теоретические подходы к ее определению и изучению, выделяются два основных аспекта – субъективная мобильность как последствия объективной мобильности, переживаемые индивидом, субъективная мобильность как оценка опыта мобильности. Дается краткий обзор основных эмпирических исследований по каждому направлению. Рассматриваются принятые способы измерения субъективной мобильности (успех, сравнение достигнутого профессионального статуса с родительским, стандарты жизни), анализируется возможность использования такого показателя, как субъективное благополучие в качестве измерения субъективной мобильности. На основе данных общероссийского опроса, проведенного в 2020 г. в рамках исследования «Факторы социального благополучия в изменяющемся и стабильном обществах», определяются четыре типа субъективной мобильности, различающиеся восприятием индивидуального опыта мобильности и оценкой благополучия родителей. Рассчитанные для каждого типа мобильности модели бинарной логистической регрессии позволили определить влияние факторов на формирование восприятия субъективной мобильности. Полученные результаты подтвердили некоторые из  тенденций, выявленных зарубежными учеными на данных международных исследований. Сделан вывод о том, что для субъективного восприятия мобильности первоочередными являются не факторы, которые можно отнести к структурным показателям, а  оценка отношений с родителями и эмоциональное самочувствие.
Firefighters under alert: psychological morbidity, empathy and alexithymia between firefighters and non-firefighters
Authors: Rodrigues Fabiana , Bártolo Ana , Santos Isabel M. , Pereira Anabela , Silva Carlos F.
Published: June 2023

Firefighters have high exposure to traumatic events and have an increased risk of developing symptoms related to trauma. The current study assessed the psychological morbidity, empathy and alexithymia of volunteer firefighters compared to career firefighters and to non-firefighter comparators from the general population. Group differences were assessed using multivariate comparisons and univariate tests and discriminant analysis for individual measures. A total of 1062 individuals completed the protocol. Considering firefighters as the focus of analysis, data suggested that both career and volunteer firefighters presented higher trauma than the comparison group. In subscales of empathy, compared to the comparison group, career firefighters scored higher on the perspective-taking scale, while firefighters showed less personal discomfort and less fantasy. Firefighters showed less alexithymia, in the outward-oriented style of thinking than the comparison group. The findings suggest the need for more prevention and treatment efforts for firefighters, with the introduction of educational and therapeutic interventions.
Optimized Lightweight Frame for Intelligent New-energy Vehicles
Authors:   Department of First, North China University of Water Resources and Electric Power, Zhengzhou, China, 450000, Wu Peipei
Published: June 2023

In this paper, a joint optimization method based on multi-objective response surface approximation model and finite element simulation program is proposed to realize the lightweight optimization of new-energy vehicle frames. Under the premise of satisfying the constraints of strength, frequency and vibration, the thickness of different important parts is optimized to achieve the goal of minimizing the quality of intelligent vehicles. In order to obtain the stress distribution of each part and the vibration frequency of the frame, various finite element analyses of the intelligent vehicle frame are analyzed. In order to achieve optimization, this paper adopts the response surface method for multi-objective optimization. Sample data was generated by the central composite design, and the response surface optimization method was used to filter out 5 design variables that had a large impact on the frame. As a result, the weight of the frame was reduced from 25.05 kg to 19.86 kg, a weight reduction of 20.7%, achieving a significant weight reduction effect. This method provides important reference value and guiding significance for the optimization of frame and its lightweight. In this way, the design of the frame can be better optimized to make it lighter, thereby improving the performance of the smart car. At the same time, this method can also be applied to optimization problems in other fields to achieve more efficient and accurate optimization goals.

Authors: Dalmora Adilson Celimar , Koetz Gabriela Melissa , Hernández Palma Hugo Gaspar , Dick Deborah , Selbacha Pedro
Published: June 2023

Abstract

The abundance of organic waste generated by agro-industrial activities leads to the need to find alternatives for adequate destinations for these. Composting is the most viable alternative due to its low cost, ease of operation and generation of a product with the possibility of economic exploitation. The objective of this work was to present the dynamics of the composting process in an organic waste processing plant in the municipality of Montenegro, RS, Brazil, as well as to present the results of chemical analyzes for the quantification of humic substances contained in the leachate resulting from the composting process. The results of the leachate revealed that it has high levels of humic substances (humic acids between 12.2 and 30.7%, fulvic acids between 12.2 and 45.5%) significantly higher than those found in the literature (9%). Leachate has humic characteristics desired for the preparation of a commercial product for use in agriculture and can be configured as an interesting extra income alternative for the economic health of the enterprise.

Keywords: organic waste; composting; humic substances; agriculture.

Authors: Dalmora Adilson Celimar , Da Silva Civeira Matheus , Do Nascimento de Campos Samuel , Hernández Palma Hugo Gaspar
Published: June 2023

The increase in the world's demand for water has become one of the most relevant topics on environmental sustainability and the conservation of water resources. As a result of the scarcity of potable water, processes such as the use of water through practices, techniques, and technologies for its efficient use have become essential for future generations. Among the possibilities for using water, air conditioning systems stand out, due to the formation of condensed water during operation. The world's population is increasingly concerned about environmental issues, showing that it is necessary to seek alternatives to recycle water, whether for use in gardening, sewage systems, washing sidewalks, and cars, among others. The present study carried out a literature review to reflect on the theme of the reuse of condensation water from air conditioners as a strategy for the sustainable use of water resources and enhancing the future of planet Earth.
GOLD DISTRIBUTION Another Look on the Generalization of Lindely Distribution
Authors: Al-Talib Mohammad , Al-Nasser Amjad , Ciavolino Enrico
Published: June 2023

In this paper, a new generalization of one parameter Lindely distribution is proposed. The new distribution is a mixture distribution of Gamma distributions with fixed scale parameter and variable shape parameter. The distribution is called 'GOLD Distribution' as it is a generalization for several distributions such as exponential, Lindely, Sujatha, Amarendra, Devya and Shambhu distributions. The probability density and cumulative density functions are derived. Also, the statistical properties of the GOLD distribution are discussed. Parameter estimation using the maximum likelihood and the method of moments are given. Moreover, an illustration of the usefulness of the GOLD distribution in survival data analysis is discussed based on a real lifetime data.

This research was a collaboration between Statistics, Psychology, and Politics. The main research variable that is radical intention has a psychological construct that is theoretically built with a social approach and political point of view. As a big country, Indonesia has various pluralism i.e ethnic and religion, so that it requires a high tolerance attitude to live in a harmony. Students as the next generation and important elements in society are expected to avoid intolerance. The research subjects were 175 students from an Islamic university in Indonesia. The data were analyzed with Ordinal Regression which intention of radicalism (ordinal) as the dependent variable, personality type (nominal), and tolerance attitude level (ordinal) as independent variables. The majority of these students have good moral values so they can tolerate the difference. From the regression analysis, the type personality and tolerance attitude have a significant effect on radicalism intention.

Estimation of unknown parameters using different loss functions encompasses a major area in the decision theory. Specifically, distance loss functions are preferable as it measures the discrepancies between two probability density functions from the same family indexed by different parameters. In this article, Hellinger distance loss function is considered for scale parameter λ of two-parameter Rayleigh distribution. After simplifications, form of loss is obtained and that is meaningful if parameter is not large and Bayes estimate of λ is calculated under that loss function. So, the Bayes estimate may be termed as ‘Pseudo Bayes estimate’ with respect to the actual Hellinger distance loss function as it is obtained using approximations to actual loss. To compare the performance of the estimator under these loss functions, we also consider weighted squared error loss function (WSELF) which is usually used for the estimation of the scale parameter. An extensive simulation   is carried out to study the behaviour of the Bayes estimators under the three different loss functions, i.e. simplified, actual and WSE loss functions. From the numericalresults it is found that the estimators perform well under the Hellinger distance loss function in comparison with the traditionally used WSELF. Also, we demonstrate the methodology by analyzing two real-life datasets.

The management of each industry must strive to meet multiple financial objectives, including capital structure, dividend policy, and earnings growth. The paper proposes an approach to analyze how financial resources should be allocated optimally using a multi-objective decision-making model. As part of the study, Al Rajhi banks' financial statements are used as a case study. All of the data is drawn from the banks' financial statements. Overall, the study's results show that all objectives have been achieved. This model enables banking and other industries to formulate strategies for dealing with various financial situations. The study's results are calculated and verified using LINGO 18.0 x64 software. Hence, the proposed model can determine financial decisions and develop strategies for dealing with various economic frameworks.
A Comparative Study of Higher Order Kernel Estimation and Kernel Density Derivative Estimation of the Gaussian Kernel Estimator with Data Application
Authors: Israel Uzuazor SILOKO , Amaju Ojobor Sunday
Published: June 2023

Higher-order kernel estimation and kernel density derivative estimation are techniques for reducing the asymptotic mean integrated squared error in nonparametric kernel density estimation. A reduction in the error criterion is an indication of better performance. The estimation of kernel function relies greatly on bandwidth and the identified reduction methods in the literature are bandwidths reliant for their implementation. This study examines the performance of higher order kernel estimation and kernel density derivatives estimation techniques with reference to the Gaussian kernel estimator owing to its wide applicability in real-life-settings. The explicit expressions for the bandwidth selectors of the two techniques in relation to the Gaussian kernel and the bandwidths were accurately obtained. Empirical results using two data sets obviously revealed that kernel density derivative estimation outperformed the higher order kernel estimation excellently well with the asymptotic mean integrated squared error as the criterion function.

Published: June 2023

The Kumaraswamy distribution is an important probability distribution used to model several hydrological problems as well as various natural phenomena whose process values are bounded on both sides. In this paper, we introduce a new family of inverse Kumaraswamy distribution and then explore its statistical properties. Conventional maximum likelihood estimators are considered for the parameters of this distribution and estimation based on dual generalized order statistics is outlined. A particular sub-model of this family; namely, the inverse Kumaraswamy- Weibull distribution is considered and some of its statistical properties are obtained. Estimation efficiency is numerically evaluated via a simulation study and two real-data applications of the proposed distribution are provided as well.

Depending on Yousof et al. (2017a), a new one parameter G family of distributions called the reciprocal Burr X-G family is defined and studied. Special member based on the well-known Burr type XII model called the reciprocal Burr X-Burr XII distribution is studied and analyzed. Relevant properties of the new family including ordinary moments, moment of the residual life, moment of the reversed residual life and incomplete moments are derived and some of them are numerically analyzed. Four different applications to real-life data sets are presented to illustrate the applicability and importance of the new family. The new family has proven to be highly capable and flexible in practical applications and statistical modeling of real data.
Remarks on the Paper ”On the product and Quotient of Pareto and Rayleigh Random Variables”
Authors: Hamedani G. G.
Published: June 2023

Obeid and Kadry (2019) tried to study the product and quotient of the independent Pareto and Rayleigh random variables. The distributions they obtained are incorrect and in fact there is no closed form distributions as discussed here. We will mention the errors made and try to establish the correct versions of the probability density functions of these distributions for the truncated Pareto and Rayleigh random variables.
