Abstract In recent years, the analysis of development conditions during the operation phase has gained attention, specially using Building Information Modeling (BIM). In this context, this research aims to delineate the frontiers of knowledge and identify future research directions with regard to the uses of BIM for the management, operation and maintenance of facilities. A mixed review method was employed, which combined scientometric analysis and a systematic literature review. To conduct the review, 4050 publications were initially retrieved from the Scopus database, which were filtered using the PRISMA protocol and resulted in 1004 publications to be analyzed. The frequency of sources and citations and the networks of co-occurrence of keywords, co-authorship of authors and countries composed the first analysis. Then, the systematic analysis of the data set was carried out, grouping the surveys into eight different categories. As a result, it was possible to identify that the field “BIM for management, operation and maintenance of facilities” is growing and that the purposes of application in this area have been expanded, in addition to there being a promising association of emerging technologies with BIM for this purpose.

Resumo Nos últimos anos a análise das condições de empreendimentos durante a fase de operação tem ganhado atenção, inclusive com o uso do Building Information Modeling (BIM). Neste âmbito, esta pesquisa tem por objetivo delinear as fronteiras do conhecimento e identificar direções de pesquisa futuras no que diz respeito aos usos do BIM para fins de gestão, operação e manutenção de instalações. Foi empregado um método misto de revisão que associou a análise cientométrica e revisão sistemática da literatura. Para condução da revisão inicialmente foram identificadas 4050 publicações da base de dados Scopus, que foram filtrados por meio do protocolo PRISMA e resultaram em 1004 publicações a serem analisadas. A frequência de fontes e citações e as redes de coocorrência de palavras-chave, de coautoria e de países compuseram a primeira análise. Em seguida, a análise sistemática do conjunto de dados foi realizada com o agrupamento das pesquisas em oito categorias diferentes. Como resultado, foi possível identificar que o campo “BIM para gestão, operação e manutenção das instalações” está em crescimento e que as finalidades de aplicação neste âmbito têm sido ampliadas, além de haver uma associação promissora das tecnologias emergentes com o BIM para este fim.

Die probleem wat hierdie studie genoodsaak het, was dat sommige oonde wat verantwoordelik was vir die verdere verwerking van staalpype by Maatskappy X nie aan 'n programmeerbare logiese beheer (PLC)-Internet of Things (IoT) stelsel gekoppel was nie. Dit het die produkvloei vertraag. Om hierdie probleem aan te spreek, is PLC-IoT-stelsels geïntegreer sodat die produksiestelsel meer effektief kon wees. Hierdie studie modelleer en simuleer dus die geïntegreerde PLC-IoT-beheerstelsel, deur die stelseldinamika-modelleringsbenadering te gebruik om die werkverrigting van die outomatiese gasoonde te ondersoek. Die PLC-IoT bestaan uit 'n interne module wat gebruik word om die datastroom te verwerk. Na die implementering van die voorgestelde beheerstelsel is primêre data verkry deur die werkverrigting van die stelsel voortdurend te evalueer. Die navorsingsmetodologie wat gebruik is, het kwantitatiewe analise en 'n simulasiemodel met behulp van die Anylogic-sagteware behels. Die resultaat van die aflewering en voorraad van blokke vanaf 'n outomatiese stelsel het 'n opwaartse neiging getoon met aflewering en 'n voorraad van 'n blokke op ongeveer 90 minute; terwyl 'n stelsel wat nie met PLC-IoT geoutomatiseer is nie, 'n afwaartse neiging van ingots getoon het. Dit wys dat die bekendstelling van die PLC-IoT vir beheer die stelsel meer effektief maak. Die bevindinge van hierdie studie kan die vervaardigers help om vervaardigings- of produksiedoeltreffendheid, aansienlike tydbesparings en beter monitering van die vervaardigingsproses te bereik.

The problem that necessitated this study was that some furnaces that were responsible for the further processing of steel pipes at Company X were not connected to a programmable logic control (PLC)-Internet of Things (loT) system. This slowed down the product flow. To address this problem, PLC-IoT systems were integrated so that the production system could be more effective. This study therefore models and simulates the integrated PLC-IoT control system, using the system dynamics modelling approach to investigate the performance of the automated gas furnaces. The PLC-IoT consists of an internal module that is used to process the data stream. After the implementation of the proposed control system, primary data was acquired by continuously evaluating the performance of the system. The research methodology used involved quantitative analysis and a simulation model using the Anylogic software. The result of the delivery and inventory of ingots from an automated system showed an upward trend with delivery and an inventory of an ingot at about 90 minutes; while a system that was not automated with PLC-IoT showed a downward trend of ingots. This shows that the introduction of the PLC-IoT for control makes the system more effective. The findings of this work could assist the manufacturers in achieving manufacturing or production efficiency, significant time savings, and better monitoring of the manufacturing process.

Abstract Purpose: To review the current advances and current of the study of consciousness in order to discuss the advantages of a research program on consciousness defined by biology and complexity sciences. Methodological design: A review of the scientific literature of consciousness showed conceptual and methodological findings and their limitations. An analysis of the methods of complexity sciences and biology was carried out to discuss how this approach is able to contribute to the study of consciousness. Results: Among the comparative development of different current theories on consciousness we have the Theory of the integration of information and the Theory of the global work area. We also present a working scheme with the methods of complexity sciences and suggest evolutionary biology as a framework for the interpretation of the results. Research Limitations: A lack of consensus on definition makes it difficult to integrate empirical data into a general theory of consciousness. Findings: Six points were discussed as necessary for the research program of evolutionary biology and complexity, such as: the adaptive functional analysis of consciousness, the emergence of modular structures, evolutionary novelties, the genetic correspondence of cognitive abilities, the effect of the environment and reciprocal causality.

Resumen: El comercio electrónico del sector de la moda ha aumentado en los últimos años en Latinoamérica, especialmente a raíz de la pandemia, sin embargo, todavía existen problemas en la aceptación de este canal de compra. La presente investigación se centra en algunos factores que podrían influir en la intención de compra y tiene como objetivos comprobar cómo en ella influyen la confianza, los riesgos percibidos, los costos y la conveniencia. Para esto, se suministró un cuestionario a 223 estudiantes de cuatro universidades del Ecuador. Para el análisis de los datos obtenidos se desarrolló un modelo PLS-SEM, en el cual la confianza en el vendedor actúa como variable mediadora en la relación entre los otros tres factores y la intención de compra. Los resultados muestran que dicho modelo tiene un aceptable poder predictivo y explicativo. Asimismo, se comprueba que los riesgos, la conveniencia y la confianza afectan significativamente a la intención de compra, pero no los costos. Además, la confianza mediaría la relación entre las tres variables y la intención de compra en línea. Se concluye que el modelo propuesto puede servir de base para estudios similares y, a su vez, se considera que los resultados obtenidos pueden ser utilizados por las empresas en el sector de la moda que quieren vender a través de plataformas de e-Commerce para el desarrollo de estrategias de marketing.

Abstract: E-commerce in the fashion sector has increased in recent years in Latin America, especially in the wake of the pandemic, however, there are still issues in the acceptance of this shopping channel. The present research focuses on some factors that could influence purchase intention and aims to test how it is influenced by trust, perceived risks, costs and convenience. For this purpose, a questionnaire was given to 223 students from four universities in Ecuador. A PLS-SEM model was developed for the analysis of the data, in which trust in the seller has a mediating role in the relationship between the other three factors and purchase intention. Results show that this model has acceptable predictive and explanatory power. Likewise, it validates that risks, convenience and trust significantly affect intention, but not costs. In addition, trust would mediate the relationship between the other variables and online shopping intention. It is concluded that the proposed model can serve as a basis for similar studies, and, at the same time, it is considered that the results obtained can be used by business in the fashion sector that pursue to sell through e-commerce platforms for marketing strategies development.

Abstract The intensification of violence and the violation of human rights in migratory crises is currently a central theme in the experimentation of graphic narratives, which have given rise to the hybrid and critical genre represented by the graphic chronicle and the graphic novel of migration. The verbo-visual treatment is analyzed in the series of twelve graphic chronicles of migration “My life as an immigrant in Chile” (2018) of Sábado Magazine, in the newspaper El Mercurio, an agent of public discourse that has consolidated stereotypes and prejudices about the migrant population. Through qualitative content analysis of the image-text articulation, the verb-visual strategies of the graphic chronicle of journalistic and literary tone are examined. The elements that confer authenticity, reliability and veracity to the chronicle were established according to the use of testimony, portraits of the protagonists and contextual data. Likewise, literary elements were determined such as the staging of vulnerability, enhancement of the cultural fabric, multiple narrative voices and the recreation of resilient resistance, which together allude to the human rights perspective. The graphic chronicle intensifies the use of the testimonial voice and omits the author (witness), but the latter appears in the verb-visual articulation in biases and introduction of the ambiguity of migration experiences, and in the relationship with the “distant near”. The graphic chronicle of migration can be significantly modulated by the mediatized public discourse, weakening its critical reading of reality.

Resumen La intensificación de la violencia y la violación a los derechos humanos en las crisis migratorias es en la actualidad una temática central en la experimentación de las narrativas gráficas, las que han originado el género híbrido y crítico representado por la crónica gráfica y la novela gráfica de migración. Se analiza el tratamiento verbo-visual en la serie de doce crónicas gráficas de migración “Mi vida como inmigrante en Chile” (2018) de la Revista Sábado, inserta en el periódico El Mercurio, agente del discurso público que ha consolidado estereotipos y prejuicios sobre la población migrante. A través de análisis de contenido cualitativo de la articulación imagen-texto se examinan las estrategias verbo-visuales de la crónica gráfica de tono periodístico y literario. Los elementos que confieren autenticidad, fiabilidad y veracidad a la crónica se establecieron de acuerdo con el del testimonio, retratos de los protagonistas y datos de contexto. Asimismo, se determinaron los elementos literarios como la puesta en escena de la vulnerabilidad, realce de la trama cultural, de las voces narrativas múltiples y la recreación de la resistencia resiliente, que en conjunto aluden a la perspectiva de derechos humanos. La crónica gráfica intensifica el uso de la voz testimonial y omite la del autor (testigo), pero este último aparece en la articulación verbo-visual en sesgos e introducción de la ambigüedad de las experiencias de la migración, y en la relación con el “lejano próximo”. La crónica gráfica de migración puede ser modulada significativamente por el discurso público mediatizado debilitando su lectura crítica de la realidad.

Abstract This paper’s research focuses on a multidimensional racism suffered by Haitians migrants in the Dominican Republic, which appears to be social and political as well. The direct experience of the author in the Dominican Republic strengthens an empirical and theoretical analysis for questioning a possible correlation between Dominican politics, nationalism, and popular support for the general exclusion, within the Dominican national system, of Haitian migrants. Through an initial review of relevant literature, from the fields of Sociology and Migration, this article defines the concept of Agamben’s Homo Sacer. Agamben’s theoretical contribution is useful to identify the state’s will to exclude Haitian migrants. In addition, Sayad’s concept of State-thinking will also be used. Moreover, the historical focus on community’s search for national identity relies on Rappaport’s works and then related to the Dominican Republic. Exclusion and marginalization of Haitian migrants is also analyzed by outlining the lack of governmental data and updated information about immigrants, leading to hypothetical correlations between State-promoted illegalization of Haitian migrants, enforced by local politics, and a social dimension of racial nationalism. With a focus on International Relations on Political Science, the study describes that the current Dominican government, headed by President Luis Abinader, shows a trend influenced by a past heritage of political realism and nationalism in its bilateral relations with Haiti, since, it is worth noting, there seems to be relevant consensus in the Dominican society for such hardline policies.

Resumen Este trabajo analiza la presencia de un racismo multidimensional, de carácter social y político, padecido por los migrantes haitianos en República Dominicana. La experiencia directa del autor en República Dominicana motiva la búsqueda de un análisis empírico y teórico que pueda interrogarse sobre una posible correlación entre el nacionalismo en la política dominicana y el apoyo popular hacia la exclusión de los migrantes haitianos en el sistema nacional dominicano. A través de una inicial revisión de la literatura de referencia del campo sociológico y migratorio, se define el concepto de Homo Sacer expuesto por Agamben. El aporte teórico de Agamben es útil para identificar la voluntad estatal de excluir a los migrantes haitianos. Además, se tomará el concepto de pensamiento de Estado identificado por Sayad, mientras que el foco histórico en la cuestión identitaria dominicana cuenta con aportes procedentes de las obras de Rappaport. La marginalización y exclusión de los migrantes haitianos se estudia también cuestionando la ausencia de datos y registros actualizados por el Gobierno dominicano, queriendo proponer eventuales correlaciones entre la ilegalización estatal de los migrantes haitianos, con el aval de la política dominicana, y una forma social de nacionalismo racial. Utilizando también un enfoque propio de las Relaciones Internacionales y la Ciencia Política, se describe cómo el actual gobierno de República Dominicana, encabezado por el presidente Luis Abinader, muestra una tendencia hacia pasados elementos de realismo político y nacionalismo en las relaciones bilaterales con Haití, donde, cabe incluir, encuentra un efectivo consenso por parte de la sociedad dominicana.

Resumen En la literatura se ha aportado evidencia que establece que el cumplimiento de las regulaciones medioambientales propicia la adopción e implementación de actividades de eco-innovación en las empresas manufactureras, ya que a través de este tipo de actividades no sólo se reducen los costos asociados a las descargas de contaminantes, sino también se incrementa el nivel del rendimiento sustentable de las empresas. Sin embargo, poco se sabe de la relación existente entre las regulaciones medioambientales, la eco-innovación y el rendimiento sustentable, ya que son pocos los estudios publicados en la literatura que se han orientado en su análisis, por lo cual este estudio tiene como objetivo llenar este vacío existente, y generar nuevo conocimiento de la relación entre estos tres constructos a través de una extensa revisión de la literatura. Asimismo, se distribuyó un cuestionario a una muestra de 460 empresas manufactureras de México, analizando los datos mediante el análisis factorial confirmatorio y los modelos de ecuaciones estructurales basados en la covarianza. Los resultados obtenidos sugieren que las regulaciones medioambientales tienen efectos positivos en la eco-innovación, y la eco-innovación tiene efectos positivos en el rendimiento sustentable de las empresas manufactureras de la industria automotriz. Bajo este contexto, los resultados obtenidos permitieron concluir que el cumplimiento de las regulaciones medioambientales establecidas por la administración pública, por parte de las empresas manufactureras de la industria automotriz, mejoran tanto las actividades de eco-innovación como el rendimiento sustentable de las organizaciones.

Abstract In the literature, evidence has been provided that establishes that compliance with environmental regulations promotes the adoption and implementation of eco-innovation activities in manufacturing firms, since through this type of activities not only are the costs associated with the discharges of pollutants, but also increases the level of sustainable performance of companies. However, little is known about the relationship between environmental regulations, eco-innovation, and sustainable performance, since there are few studies published in the literature that have focused on their analysis, so this study aims to fill this existing gap, and generate new knowledge of the relationship between these three constructs through an extensive review of the literature. Likewise, a questionnaire was distributed to a sample of 460 manufacturing firms in Mexico, analyzing the data through confirmatory factor analysis and structural equation models based on covariance. The results obtained suggest that environmental regulations have positive effects on eco-innovation, and eco-innovation has positive effects on sustainable performance of manufacturing firms in the automotive industry. In this context, the results obtained allowed us to conclude that compliance with environmental regulations established by the public administration, by manufacturing firms in the automotive industry, improve both eco-innovation activities and sustainable performance of organizations.

ABSTRACT: This research evaluated different rice genotypes regarding physicochemical and instrumental parameters of grain quality and associated the data with sensory analysis to support the creation of rules for classification of the culinary quality of rice (texture), based on isolated or combined parameters. The combination of amylose content and gelatinization temperature was able to predict the rice quality. According to the sensorial panel, the instrumental stickiness was able to segregate rice with very low amylose content or waxy to the other ones. Regarding pasting properties, rice that presented high final viscosity (310-480 RVU), setback (165-245 RVU), and pasting temperature (78 - 88 °C), and low values for breakdown (15-120 RVU), associated with a high stickiness (>-5N) was desirable by the Brazilian consumers. The classification rules created through the relationship between the physicochemical parameters and the texture profile evaluated by the sensory panel will help to verify the culinary profile of the rice samples (through free software), which makes it easier to predict the probability of rice meeting the desired quality standards.

RESUMO: Este trabalho avaliou diferentes genótipos de arroz quanto a parâmetros físico-químicos e instrumentais de qualidade do grão e associou os dados à análise sensorial para subsidiar a criação de regras de classificação da qualidade culinária do arroz (textura), com base em parâmetros isolados ou combinados. A combinação do teor de amilose e temperatura de gelatinização foi capaz de predizer a qualidade do arroz. De acordo com o painel sensorial, a pegajosidade instrumental foi capaz de segregar arroz com baixo teor de amilose ou ceroso dos demais. Em relação às propriedades de pasta, o arroz que apresentou alta viscosidade final (310-480RVU), retrogradação (165-245RVU) e temperatura de pasta (78-88 °C) e baixos valores de quebra pasta (15-120RVU), associados a uma alta pegajosidade (> -5N) será desejável pelos consumidores brasileiros. As regras de classificação criadas por meio da relação entre os parâmetros físico-químicos e o perfil de textura avaliado pelo painel sensorial ajudarão a verificar o perfil culinário das amostras de arroz (por meio de um software livre), o que torna mais fácil prever a probabilidade de o arroz atender aos padrões de qualidade desejados.

Riassunto L’articolo esamina l’ipotesi, formulata qualche anno fa da Pilar Lorenzo (2013 e 2016), secondo la quale i Lais de Bretanha circolarono in maniera indipendente e in ordine diverso. Una nuova analisi dei dati positivi non permette di confermare questa teoria. Indipendentemente dall’ordine primitivo delle cantigas ‘bretoni’, è altamente probabile che i Lais e le rispettive rubriche siano state composte in due momenti distinti. In particolare, la redazione delle rubriche potrebbe risalire all’epoca in cui i Lais furono inseriti nell’exemplar dei Canzonieri portoghesi di Colocci e, di conseguenza, l’ultima pericope della rubrica di B1 (Este lais posemos acá porque era o melhor que foi feito) giustificherebbe, non la prima posizione che il testo venne ad assumere nella Laissammlung, bensì la funzione di ‘prologo in versi’ che il compilatore aveva assegnato a B1 nella sua collezione di cantigas. L’articolo, inoltre, aggiunge alcuni elementi che convergono con l’ipotesi - già a suo tempo formulata da Carolina Michaëlis de Vasconcellos - secondo la quale D. Pedro, Conte de Barcelos (e la sua cerchia aristocratica) sarebbe stato il responsabile dell’inserimento dei Lais nell’exemplar e della redazione delle rubriche.

Abstract The paper examines the hypothesis, put forward a few years ago by Pilar Lorenzo Gradín (2013 and 2016), according to which the Lais de Bretanha would have circulated independently and in a different order. A new analysis of the positive data does not confirm this theory. Regardless of the primitive order of the ‘Breton’ cantigas, it is highly probable that the Lais and the associated rubrics were composed at two different times. In particular, the rubrics could be written at the time when the Lais were inserted in the exemplar of the Colocci’s Portuguese Cancioneiros and, consequently, the last sentence of the rubric of B1 (Este lais posemos acá porque era o melhor que foi feito) could justify, not the first position that the text came to assume in the Laissammlung, but the function of “prologue in verse” that the compiler had assigned to B1 in the structure of the collection of cantigas. In addition, the article adds some elements that agree with the hypothesis - already put forward by Carolina Michaëlis de Vasconcellos - according to which D. Pedro, Earl of Barcelos (and his aristocratic circle) was responsible for the insertion of the Lais into the exemplar and the redaction of rubrics.

RESUMO Introdução: Embora a maioria dos indivíduos recupere após a infeção aguda por SARS-CoV-2, outros podem apresentar sintomas persistentes com potenciais consequências a médio e longo prazo no desempenho de atividades e participação, com eventuais implicações na sua aptidão para o trabalho. Objetivo: Analisar a persistência de sintomas aos doze meses após infeção por SARS-CoV-2 e perceção do nível de desempenho em atividades e participação em situações de vida de trabalhadores do setor industrial numa empresa da Região de Aveiro. Metodologia: Estudo observacional, desenvolvido num Serviço de Saúde Ocupacional de uma empresa industrial da região de Aveiro, incluindo trabalhadores com teste SARS-COV-2 RT-PCR/TRAg positivo, entre outubro/2020-janeiro/2022. Após sinalização da infeção, a Equipa de Saúde Ocupacional aplicou um questionário recolhendo as variáveis sociodemográficas, uma lista de sintomas comuns durante a fase aguda da infeção por SARS-COV-2 e a funcionalidade percebida avaliada pela versão portuguesa da WHODAS 2.0-PT12 (onde '12 pontos' significa a maior funcionalidade). Aos doze meses, preencheram outra lista de sintomas persistentes após a infeção por SARS-CoV-2 e novamente a WHODAS 2.0-PT12. A análise dos dados incluiu estatística descritiva e regressão logística univariada e multivariada. A condução da análise foi realizada com o software JASP 0,16.3. Resultados: Oitenta e cinco trabalhadores encontravam-se infetados com SARS-CoV-2, com idade média de 36,1±9,8anos, 77,7% eram do sexo masculino, 36,7% possuíam escolaridade superior e 17,7% relataram pelo menos uma condição crónica. Aos doze meses, trinta trabalhadores (35,3%) relataram sintomas persistentes, sendo a fadiga (27,7%) e artralgia (14,4%) os mais mencionados. A média da WHODAS 2.0 nos dois momentos de avaliação foi 19,2±8,0 vs 15,7±5,0. Foram encontradas associações significativas entre os itens da WHODAS 2.0 e os sintomas persistentes fadiga, cefaleia, tosse, mialgia, artralgia e doença crónica prévia. Conclusões: Os sintomas persistentes doze meses após a infeção aguda por SARS-CoV-2 têm repercussão na autoperceção do desempenho em algumas atividades e participação em situações de vida dos trabalhadores. A equipa de saúde ocupacional deve realizar a vigilância contínua da saúde do trabalhador infetado, avaliando a presença de sintomas persistentes desta infeção e poderá implementar um programa de intervenção individualizado, que minimize o impacto da persistência dos sintomas no seu desempenho laboral, assim como, em atividades e participação em situações de vida.

ABSTRACT Introduction: Although most individuals recover after acute infection by SARS-CoV-2, others may suffer from persistent symptoms with potential medium and long-term consequences on the performance of activities and participation, with possible implications for their fitness for work. Objective: To analyze the persistence of symptoms twelve months after SARS-CoV-2 infection, and the perception of the performance level in activities and participation in life situations, of workers in a company of the industrial sector in the Aveiro Region. Methodology: An observational study, developed in an Occupational Health Service of an industrial company in the region of Aveiro, including workers with positive SARS-COV-2 RT-PCR/TRAg test, between October/2020-January/2022. After signaling the infection, the Occupational Health Team applied a questionnaire collecting sociodemographic variables, a list of common symptoms during the acute phase of infection by SARS-COV-2, and the perceived functionality assessed by the Portuguese version of WHODAS 2.0-PT12 (where '12 points' means the most functionality). At twelve months, they filled out another list of persistent symptoms after SARS-CoV-2 infection and again WHODAS 2.0-PT12. Data analysis included descriptive statistics and univariate and multivariate linear regression. The analysis was conducted with the software JASP 0.16.3. Results: Eighty-five workers were infected with SARS-CoV-2, with a mean age of 36.1± 9.8years, 77.7% were male, 36.7% had higher education and 17.7% reported at least one chronic condition. At twelve months, thirty workers (35.3%) reported persistent symptoms, with fatigue (27.7%) and arthralgia (14.4%) being the most mentioned. The mean WHODAS 2.0 in the two evaluation moments was 19.2±8.0 vs 15.7±5.0. Significant associations between WHODAS 2.0 items and persistent symptoms of fatigue, headache, cough, myalgia, arthralgia, and previous chronic disease were found. Conclusions: Persistent symptoms twelve months after acute SARS-CoV-2 infection have repercussions on workers' self-perception of performance in some activities and participation in life situations. The occupational health team can implement continuous surveillance of the infected worker's health, assess the presence of persistent symptoms of this infection, and implement an individualized rehabilitation program, which minimizes the impact of the persistence of symptoms on their work performance, and in activities and participation in life situations.

Resumo Este estudo tem como objetivo identificar as diferenças entre as ações de marketing verde e de tendência ao greenwashing, bem como suas implicações para as práticas de desenvolvimento socioambiental das empresas, com base em dados do Banco do Brasil S.A. e Natura & Co. Utilizou-se uma pesquisa qualitativa, descritiva e estudo de caso múltiplo, realizado com análise de documentos, como relatórios anuais, além de outras informações disponíveis aos consumidores pelas duas empresas em seus sites. A análise documental foi orientada pela check-list construída a partir da revisão teórica. A pesquisa evidenciou que as duas organizações analisadas seguem princípios éticos na publicização de suas ações no âmbito da sustentabilidade, nas dimensões ambiental e social, configurando desta forma o modelo de marketing verde, preconizado na literatura científica, distanciando-se da tipificação de greenwashing. Tanto o Banco do Brasil como a Natura & Co. demonstram, por meio de relatórios disponibilizados em seus sites, a realização de ações e apoio a projetos, tanto sociais, como ambientais, que, ao serem objeto de comunicação ao mercado e stakeholders, evidenciam características de veracidade, com indicação de fontes e documentos que comprovam a efetiva execução de ações citadas. Destarte, é possível inferir que se trata de marketing verde e não greenwashing.

Abstract This study aims to identify the differences between green marketing initiatives and greenwashing, as well as their implications for companies’ social and environmental development practices. It relies on data from Banco do Brasil S.A. and Natura & Co. A qualitative, descriptive and multiple case study was employed, involving an analysis of documents such as annual reports and other publicly available information on the companies’ websites. The documentary analysis was guided by the checklist developed from the theoretical review. The research findings indicate that both organisations analysed adhere to ethical principles when communicating their sustainability efforts in environmental and social dimensions, thus aligning with the green marketing model advocated in scientific literature and distancing them from the representation of greenwashing. Banco do Brasil and Natura & Co., as evidenced in reports available on their websites, demonstrate genuine actions and support projects in both social and environmental domains. Communication with the market and stakeholders includes verifiable details, sources, and documents, establishing credibility and affirming that the reported actions were indeed implemented. Consequently, it is possible to infer that the practices observed align with green marketing rather than greenwashing.

RESUMEN Este artículo presenta los resultados de una investigación empírica cuyo objetivo fue identificar factores críticos que contribuyeron para la culminación exitosa de los itinerarios formativos de un grupo de graduados de Educación de Jóvenes y Adultos Integrada con la Formación Profesional en el nivel secundario brasileño. Se aplicó un análisis de contenido a los datos obtenidos a través de entrevistas semidirigidas a diez graduados. Exploramos la noción de posicionamiento, como fenómeno social que circunscribe la posición que ocupa un individuo o grupo en un sistema social determinado (Bernstein, 1996) en línea con las disposiciones socioafectivas y cognitivas relacionadas con los procesos de placer/displacer presentes en el contexto escolar y con las representaciones y concepciones de los contenidos, respectivamente (Bourgeois, 1999). Los resultados apuntan a la elevación del posicionamiento en estructuras jerárquicas circunscritas por la escolaridad, el aprendizaje, el conocimiento, las relaciones sociocognitivas y la perspectiva profesional, que se correlacionan con el desarrollo de disposiciones socioafectivas y cognitivas en las dimensiones motivaciones, aspiraciones, valores apropiados y características curriculares, concretamente aprendizaje colaborativo y metodología de enseñanza.

RESUMO Este artigo apresenta os resultados de uma pesquisa empírica cujo objetivo foi identificar fatores críticos que contribuíram para o sucesso na conclusão dos percursos formativos de um grupo de egressos da Educação de Jovens e Adultos Integrada à Formação Profissional no nível secundário brasileiro. Foi aplicada a análise de conteúdo dos dados obtidos através de entrevistas semi-dirigidas com dez egressos. Exploramos a noção de posicionamento, enquanto fenômeno social que circunscreve a posição que um indivíduo ou grupo ocupa num dado sistema social (Bernstein, 1996) em consonância com as disposições socioafetivas e cognitivas relacionadas com os processos de prazer/desprazer presentes no contexto escolar e com as representações e conceções do conteúdo, respetivamente (Bourgeois, 1999). Os resultados apontam para a elevação do posicionamento em estruturas hierárquicas circunscritas pela escolaridade, aprendizagem, conhecimento, relações sociocognitivas e perspectiva profissional, as quais estão correlacionadas com o desenvolvimento de disposições socioafetivas e cognitivas nas dimensões motivações, aspirações, valores adequados e características curriculares, nomeadamente aprendizagem colaborativas e metodologia de ensino.

Abstract This article presents the results of an empirical study whose aim was to identify critical factors that contributed to the successful completion of the educational trajectories of a group of former students of a Brazilian secondary level course integrating Youth and Adult Education with Vocational Education. Content analysis was applied to the data obtained through semi-directive interviews with ten former students. We explored the notion of positioning, as a social phenomenon that circumscribes the position that an individual or group occupies in a given social system (Bernstein, 1996) in line with the socio-affective and cognitive dispositions related to the processes of pleasure/displeasure present in the school context and with the representations and conceptions of the content, respectively (Bourgeois, 1999). The results point to higher positioning in hierarchical structures circumscribed by schooling, learning, knowledge, socio-cognitive relations, and professional outlook, which are correlated with the development of socio-affective and cognitive dispositions in the dimensions of motivations, aspirations, appropriate values and curricular characteristics, namely collaborative learning, and teaching methodology.

Resumen (Introducción): El cultivo de madera sostenible pierde terreno ante la producción agrícola y otros usos de la tierra; para contrarrestar esto, es necesario entender de qué manera el ente productor toma decisiones en la adopción voluntaria de sistemas agrícolas. Por consiguiente, deben diseñarse esquemas de manejo ajustados a cómo los pequeños productores gestionan los sistemas productivos de una forma voluntaria. (Objetivo): Identificar los factores que influyen en el proceso de toma de decisiones de los pequeños grupos productores que deben ser considerados para la promoción del cultivo de madera. (Metodología): Se aplicaron encuestas con preguntas abiertas y selección única al 100 % de los entes productores (N = 77) de dos asentamientos del INDER. Por la complejidad de las interacciones entre factores, se simplificó el análisis a cuatro enfoques. La tendencia de los datos se graficó a partir de un modelo de regresión local (LOESS), en el cual la curva de regresión se generó y suavizó con el uso de la función geom_smooth del lenguaje estadístico R. (Resultados): Se identificó un total de 162 interacciones entre factores indirectos y directos, estas mismas se clasificaron en tres grupos según las veces que el sujeto productor cambió de sistema de producción en periodos cortos (cinco años). Así, el Grupo A tuvo una mayor representación en la población con un 67.5 %, le siguieron el Grupo B con un 24.7 % y el Grupo C con un 7.8 %. El 67.5 % no se encontraba de acuerdo en incluir el cultivo de madera. (Conclusiones): Se demostró la existencia de factores de decisión que influyen en cómo el sujeto productor adopta los sistemas agrícolas contrarios al cultivo de madera. La venta segura (VS) es uno de ellos; por lo tanto, hasta que no se ajusten los esquemas de manejo forestal actuales, la posibilidad de una adopción espontánea es mínima y seguirá necesitando de ayudas financieras.

Abstract (Introduction): Sustainable timber cultivation is losing ground to agricultural production and other land uses; To counteract this, it is necessary to understand how the farmer makes decisions. Therefore, management schemes must be designed that adjust to the way in which small farmers manage productive systems on a voluntary basis. (Objective): Identify the factors that influence the decision-making process of small farmers that must be considered for the promotion of timber cultivation. (Methodology): Surveys with open questions and single selection were applied to 100% of the farmers (N = 77) of two INDER settlements. Due to the complexity of the interactions between factors, the analysis was simplified into four approaches. The data trend was plotted from a local regression model (LOESS), in which the regression curve is generated and smoothed with the use of the geom_smooth function of the R statistical language. (Results): A total of 162 interactions between Indirect and Direct factors. They were classified into three groups according to the number of times the farmer changed the production system in short periods (5 years). Group A has a greater representation in the population with 67.5 %, followed by Group B with 24.7 % and Group C with 7.8 %. 67.5 % of the farmers did not agree to include the cultivation of wood. (Conclusions): It was possible to demonstrate the existence of decision factors that influence the way in which the farmers adopt the agricultural systems contrary to the cultivation of wood. Safe selling (VS) is one of them; therefore, until current forest management schemes are adjusted, the possibility of spontaneous adoption is minimal and will continue to require financial aid.

Abstract The present article analyzes the relationship between Explosive Detonation Velocity (VOD), vibration, and noise generated in 16 drilling and blasting tests in two arched horizontal galleries located at different altitudes with respect to the city of Zaruma, which is situated at an altitude of 1,194 meters above sea level. Nine tests were conducted in the working face called "Apófisis," located at an altitude of 1,155 meters above sea level and 1,650 meters horizontally from the center of Zaruma. The following seven tests were carried out in the "Matamoros" face, located at an altitude of 1,116 meters above sea level and 1,389 meters horizontally from the center of Zaruma. In the "Apófisis" face, two explosive initiation systems were used: the conventional system with detonators and slow fuse, and the assembled system with quick ignition fuse, connectors, slow fuse, and detonators. The same two explosive initiation systems were also used in the "Matamoros" face. The drilled holes had a diameter of 38 mm and depths of 1.10 m and 1.50 m, aiming to maintain the horizontal shape of the gallery and parallelism between each hole (with some cases having angles of deviation ranging from 23 to 26 degrees). Both ANFO and Agricultural Ammonium Nitrate explosives were used, placed under compressed air pressure using a "gun" type pneumatic loader. The recorded data includes a minimum VOD of 3,950 m/s, a maximum VOD of 5,310 m/s, a minimum resultant vibration of 2.17 mm/s, a maximum resultant vibration of 11.5 mm/s, and minimum noise levels of 164 dB up to a maximum of 195 dB. These vibration and noise levels were compared with the current national regulations in Ecuador and international regulations in the United States. The analysis indicates that the influence of the blast in terms of VOD, vibration, and noise is within a range of 60 m to 80 m around the explosion, which does not affect the nearest infrastructure related to mining operations (offices and camps) and does not propagate to the city of Zaruma. It is important to highlight that tests using ANFO as a bottom and column charge showed lower vibrations, lower detonation velocity (VOD), and lower noise compared to the use of emulsions and agricultural ammonium nitrate.

Resumen El presente artículo analiza la relación entre la Velocidad de Detonación del Explosivo (VOD), la vibración y el ruido generados en 16 ensayos de perforación y voladura en dos galerías horizontales abovedadas ubicadas a diferentes altitudes con respecto a la ciudad de Zaruma, que se encuentra a una altitud de 1.194 m.s.n.m. Se realizaron 9 ensayos en el Frente de trabajo denominado "Apófisis", ubicado a una altitud de 1.155 m.s.n.m. y a una distancia horizontal de 1.650 m. del centro de la ciudad de Zaruma. Los siguientes 7 ensayos se llevaron a cabo en el Frente "Matamoros", ubicado a una altitud de 1.116 m.s.n.m. y a una distancia horizontal de 1.389 m. del centro de la ciudad de Zaruma. En el Frente "Apófisis", se utilizaron dos sistemas de iniciación de explosivos: el convencional, con fulminante y mecha lenta, y el ensamblado, con mecha rápida de ignición, conectores, mecha lenta y fulminantes. En el Frente "Matamoros", también se utilizaron estos dos sistemas de iniciación de explosivos. Los barrenos perforados tenían un diámetro de 38 mm y profundidades de 1.10 m. y 1.50 m. Se utilizaron tanto ANFO como Nitrato de Amonio Agrícola como explosivos, colocados bajo presión de aire comprimido utilizando un cargador neumático tipo "pistola". Los datos registrados incluyen una VOD mínima de 3.950 m/s hasta una VOD máxima de 5.310 m/s, una vibración resultante mínima de 2,17 mm/s y una vibración resultante máxima de 11,5 mm/s, y niveles de ruido mínimos de 164 dB hasta un máximo de 195 dB. Estos niveles de vibración y ruido se compararon con la normativa nacional vigente en Ecuador y la normativa internacional de Estados Unidos. El análisis indica que la influencia de la explosión de las voladuras en términos de VOD, vibración y ruido se encuentra en un rango de 60 m. a 80 m. alrededor de la explosión, lo que no afecta a la infraestructura más cercana propia de la labor minera y no se propaga hasta llegar a la ciudad de Zaruma. Es importante destacar que los ensayos con ANFO como carga de fondo y de columna presentaron menores vibraciones, menor velocidad de detonación (VOD) y menor ruido en comparación con el uso de Emulsiones y Nitrato de Amonio Agrícola.
