Implementación del secado mecánico de café en carros secadores
Authors: Buitrago Bermúdez Oscar , Ospina M. Julio E. , Álvarez G. José
Published: August 2021

Con el objetivo de presentar una nueva alternativa de secado a los pequeños y medianos caficultores, se desarrolló un secador mecánico de capa fija, a partir de un secador solar de tradicional uso en la zona cafetera denominado carro secador, el cual consta de dos a cuatro plataformas de secado, un entramado de soporte y desplazamiento de las plataformas y un techo de teja de zinc para resguardarlas en caso de lluvia.
Se hicieron las modificaciones necesarias para convertir el carro secador en un secador mecánico, se tuvo en cuenta que el secador pudiera seguirse usando como secador solar, se realizaron seis pruebas de secado, en las cuales se midieron variables del grano, del aire y del secador. La uniformidad del contenido de humedad final del grano se determinó comparando muestras tomadas en las plataformas y después de empacado el grano. De la evaluación del equipo se hicieron las siguientes deducciones:
— Cada una de las partes acondicionadas al carro funcionaron satisfactoriamente. No se presentaron fugas de aire caliente.— El consumo de combustible del quemador de olla fue 0.239 y 0.275 L.kg-1 café pergamino seco (c.p.s.) — El caudal de aire aumento al final del secado alrededor del 90%, debido a la disminución continua del espesor de la capa de grano. — Los consumos energéticos del secador estuvieron 4500 y 7000 kJ.kg-1 c.p.s. — El contenido de humedad final del grano fue uniforme, con coeficientes de variación cercanos al 10%.
La política tecnológica en el proceso de apertura y modernización de la economía colombiana
Authors: López Arcesio
Published: August 2021

El proceso de apertura económica y modernización de la base productiva comenzó recientemente en Colombia y se ha manifestado principalmente en la remoción de trabas al comercio exterior. Adicionalmente se ha tomado otro tipo de medidas que constituyen una importante renovación económica del país, como son la abolición casi total de las restricciones a la inversión extranjera y las reformas financiera, cambiaria y laboral que muestran alto grado de coherencia. Recientemente también se han diseñado los lineamientos generales de una política tecnológica; sin embargo, no se observa entre estas dos actividades paralelas puntos tangenciales de refuerzo que eviten la preocupación ante un posible tratamiento aislado de la variable tecnológica en la estrategia económica nacional.
Investigación y proceso: esencia de la formación de ingenieros químicos
Authors: Bogoya M. Daniel , Carballo S. Luis
Published: August 2021

En este trabajo se plantea una metodología para la confección de un currículo de ingeniería química, partiendo de la concepción de un modelo de educación superior conducente a satisfacer combinadamente una demanda solvente y orientada, obediente e inmediatista, proveniente de los anhelos de producción de la industria química; la pretensión de un mejoramiento del medio de vida del profesional, que intenta un ascenso en todos los órdenes; los planes del Estado en materia de desarrollo industrial y económico, aún desarticulados entre sectores y en términos del tiempo; y el papel estratégico que la universidad debe jugar en una sociedad, dependiente también en el ámbito de la ingeniería química, donde se hace indispensable que los intelectuales asuman la responsabilidad de concebir y conducir con audacia los procesos de innovación que se requieren.
Con base en este entorno se proponen como ejes centrales, para la formación de ingenieros químicos: la generación de una cultura investigativa que como actitud ante la vida forje un espíritu crítico, dispuesto a explorar otros caminos; y el dominio de las características que permitan entender un proceso químico y sus interacciones con la energía, la economía y el medio ambiente, donde interviene sistemáticamente un amplio conjunto de conceptos, posible de organizar de diferentes maneras y de sintetizar en un código fijo que se va actualizando permanentemente. Así, el primer eje tiene que ver fundamentalmente con la metodología y el segundo con los contenidos.
La metodología propuesta implica archivar el paradigma de la “clase magistral”, para pasar al del “seminario investigativo”, ya usual en otras sociedades. Aquí se busca que cada educando protagonice su propia existencia y esculpa su propia estatua, en lugar de seguir única, callada y obedientemente la huella dejada por el docente. La organización de los contenidos implica una visión orgánica, para que cada concepto se enlace con aplicaciones, invirtiendo la pirámide: la integración de conceptos abstractos con el mundo físico debe prevalecer desde el primer semestre; y la profundización de conceptos debe incrementarse en el tiempo para prevalecer en los últimos semestres.
Full Model Selection Problem and Pipelines for Time-Series Databases: Contrasting Population-Based and Single-point Search Metaheuristics
Authors: Pérez-Castro Nancy , Acosta-Mesa Héctor Gabriel , Mezura-Montes Efrén , Cruz-Ramírez Nicandro
Published: August 2021

The increasing production of temporal data, especially time series, has motivated valuable knowledge to understand phenomena or for decision-making. As the availability of algorithms to process data increases, the problem of choosing the most suitable one becomes more prevalent. This problem is known as the Full Model Selection (FMS), which consists of finding an appropriate set of methods and hyperparameter optimization to perform a set of structured tasks as a pipeline. Multiple approaches (based on metaheuristics) have been proposed to address this problem, in which automated pipelines are built for multitasking without much dependence on user knowledge. Most of these approaches propose pipelines to process non-temporal data. Motivated by this, this paper proposes an architecture for finding optimized pipelines for time-series tasks. A micro-differential evolution algorithm (µ-DE, population-based metaheuristic) with different variants and continuous encoding is compared against a local search (LS, single-point search) with binary and mixed encoding. Multiple experiments are carried out to analyze the performance of each approach in ten time-series databases. The final results suggest that the µ-DE approach with rand/1/bin variant is useful to find competitive pipelines without sacrificing performance, whereas a local search with binary encoding achieves the lowest misclassification error rates but has the highest computational cost during the training stage.
Batch Conversion of Methane to Methanol Using Copper Loaded Mordenite: Influence of the Main Variables of the Process
Authors: Mojica Molina Hebert Rodrigo , González Montiel Marlene , Navarro Frómeta Amado Enrique
Published: August 2021

Due to the demands of oxygenated derivatives of hydrocarbons for the industry, the methane (CH4) to methanol (MeOH) conversion through solid-state catalysis is a current topic, with definite questions and specific challenges. This work shows a statistical model that predicts the quantity of methanol produced through a batch conversion process employing copper-exchanged mordenite in accordance with a full factorial experimental design. Synthesis was performed through solid-state ion exchange from Cu(acac)2 and NH4-Mordenite, obtaining weight percentages (%Cu) of 1%, 3%, and 5%, which was followed by activation through calcination at a range of temperatures (Tcal) between 300-500 °C, as well as a reaction with methane under 2-10 bar pressure (P) in static conditions employing a batch reactor. The quantities of MeOH produced, and their yields were determined through a gas chromatography and mass spectrometry analysis of the reaction samples. Finally, the role and contribution of each of the variables considered in the conversion process were analyzed. By using a nonlinear model, a quadratic dependence with %Cu and P in the studied range of the variables was found, as well as a linear dependence with Tcal. Finally, for this experiment, the highest yields (µmol/g) were obtained with the following conditions: %Cu=3 %, P=6 bar, and Tcal=400 °C.

Subjectivity in megaprojects: a support strategy for social risk measurement processes
Authors: Santana da Silva Bárbara , Oliveira de Araujo Fernando , Silveira Abreu Chrystyane Gerth , Silveira Faria Marcio Carapeto
Published: August 2021

This paper studies disturbances in social risks management generated by subjectivity using the case of the engineering megaprojects developed by a large Brazilian energy company and based on the percep­tion of professionals participating in meetings for discussing the subject. This work also seeks to systematize the analysis of this issue within a framework for supporting social risk assessment processes. Methodologi­cally, the study involved interviews to 18 out of the 31 participating in­dividuals of the social risk assessment technical meetings, having a questionnaire validated by the academic literature as the starting point. Results confirm the interference of subjectivity in social risks assessment and allow identifying that variables such as training/education, experi­ence on the job, and professional background create personal judgments that may compromise the technical process of social risks measurement. The research proposes a conceptual framework in which the main inter­fering subjectivity factors are correlated, giving an account of the existing distortions in the process for measuring social risks, which in the context of megaprojects could generate strong impacts on the financial performance, reputation, and the direct stakeholders of a given project.
La teoria efectual y el fracaso empresarial
Authors: Dupleix María Dolores
Published: August 2021

La teoría efectual y el fracaso empresarial son dos temas centrales en el campo del emprendimiento. La efectuación es un modelo de comportamiento emprendedor y el fracaso es uno de los resultados posibles de todo nuevo emprendimiento. Estudios previos han intentado relacionar ambas temáticas, aunque de manera conceptual, y no existe una definición precisa ni evidencia empírica que fundamente tal vínculo. En el presente estudio se utiliza la teoría de la efectuación para analizar casos de emprendimientos que fracasaron, mediante un análisis fenomenológico interpretativo en el sector de software y servicios informáticos de Argentina. Se encontró que, no obstante, la lógica efectual es compatible con el desarrollo de emprendimientos en sectores dinámicos, dada su flexibilidad y maleabilidad ante la incertidumbre y el cambio, la supervivencia de estos depende de cómo los emprendedores utilizan y superan las debilidades de la lógica efectual. Dependiendo de cómo o cuándo se aplica este modelo de comportamiento emprendedor, puede al mismo tiempo conducir al “éxito” o impedir el progreso de los nuevos emprendimientos. Estos resultados enriquecen la literatura de efectuación, que aún se encuentra en un nivel intermedio de desarrollo empírico, y contribuyen a la literatura existente sobre fracaso al ofrecer un nuevo enfoque para su análisis.
Itiner(r)antes y subjetives
Authors: Peinador Minerva
Published: August 2021

En esta contribución propongo un recorrido por la historiografía, los estudios de la memoria y la crítica literaria y conceptos teóricos relevantes que interrelacionan estas disciplinas para, seguidamente, ensayar su aplicación en el contexto de los estudios de historia de vida en relación con la migración transnacional forzada por motivos económicos y sus efectos como conflicto colectivo del Sur al Sur global. Para su puesta en práctica recurro a la historia de vida y la historia oral como metodologías historiográficas: realizo una entrevista a Cheikh Gueye, senegalés-platense migrante representante de la extensa comunidad senegalesa en la ciudad de La Plata, Argentina. La entrevista se enmarca dentro de la problemática de la migración transnacional desde África a América Latina de generaciones de hombres jóvenes motivada por las consecuencias económicas del pasado colonial y la globalización. En ella, Gueye configura su historia de vida con su testimonio. Si bien recurro a conocimientos procedentes de diversas disciplinas, el objetivo de este trabajo no es solo reflexivo, sino que persigue desarrollar un proceso de aprendizaje de escucha con la ayuda de la creación de enlaces la teoría y la práctica.
Paul Claudel et la modernité médiévale
Authors: Jean-François Poisson-Gueffier
Published: August 2021

Les détracteurs de Claudel n’ont cessé de le présenter comme un poète ancré dans le Moyen Âge chrétien. L’inspiration médiévale de Claudel, sensible de Tête d’Or au Chemin de la Croix n° 2, dénierait ainsi à son art toute modernité. En considérant l’intégralité de son œuvre, il apparaît que le Moyen Âge n’implique en rien une régression. Le Moyen Âge claudélien est beaucoup plus vaste qu’on ne l’imagine : il n’est pas uniquement chrétien mais accueille toutes les traditions du monde. Il ne fait pas seulement revivre les genres et formes de ce passé, mais les hybride. Le Moyen Âge est dès lors moins tourné vers le passé que vers l’avenir et semble, à sa manière, infiniment plus moderne que celui de ses contemporains. C’est ce que nous tentons de démontrer dans un essai à paraître chez Honoré Champion en mars 2022, Paul Claudel et le Moyen Âge.

Compte rendu
Corporealities to the limit
Authors: Coca Diana
Published: August 2021

I propose a theoretical-practical approach to the presentation and representation of the female body in artistic creation. That is, the use of the body as a space at the limit, liminal, of danger and transgression, with the consequent potentially re-signifying effects of territory and common space through art. This narration is accompanied by the dissection of the creative process in phases and its final product, where I start from my own body, as testimony, meeting place, object and subject, studying its relationship with the context in an act of defiance to patriarchal authority. In this sense, we could relate it to the de-hierarchisation and proximity to others, in an unregulated but vital encounter of desiring, non-docile subjectivities, which eroticize politics with their irruption into the public sphere, with the intention of living, creating, loving, inventing another society, another perception of the world and other value systems.
Medición de percepción de la calidad de vida con respecto a la satisfacción con el transporte público en Costa Rica
Authors: Allen Jaime , Zúñiga López Andrea
Published: August 2021

El tema de movilidad es cada vez de mayor importancia en Costa Rica, por tanto, se vuelve cada vez más relevante mejorar el sistema del transporte público en el país. Para determinar cuáles elementos del sistema de transporte público en Costa Rica afectan la calidad de vida según la percepción del usuario es necesario conocer su opinión respecto a las condiciones en que se le proporciona el servicio. Para la identificación de los componentes de la estructura del sistema de transporte público en Costa Rica que tienen una mayor afectación en la calidad de vida de sus usuarios, se analizaron los resultados de una Encuesta de percepción sobre el efecto del uso del transporte público en la calidad de vida, este estudio se llevó a cabo por medio de un cuestionario aplicado a funcionarios y estudiantes de la Universidad de Costa Rica (UCR). Se utilizó como herramienta de análisis los Modelos de Ecuaciones Estructurales (SEM), los cuales son una herramienta estadística multivariada que permite estudiar la relación que hay entre variables latentes y observadas. Se verificó con el modelo de ecuaciones estructurales que la satisfacción con el uso del transporte público es un dominio que afecta la satisfacción con la calidad de vida, es decir, para los costarricenses la percepción de estar satisfechos con su calidad de vida se ve influenciada por la percepción de satisfacción que tengan del uso del transporte público.

El principal objetivo de este documento es el diseño mecánico de un tanque de almacenamiento elaborable con materiales de fácil obtención, que permite la toma de muestras necesarias para estudiar el almacenamiento del asfalto modificado a condiciones críticas. Paralelamente, se establecen las bases para el planteamiento de un modelo que aporte en la determinación de tiempos de almacenamiento máximo con la pretensión de verificar la calidad del diseño del asfalto modificado.
Evaluación del desempeño de los pavimentos rígidos en Costa Rica
Authors: Montes de Oca Hidalgo Maria Paula , Sequeira Rojas Wendy , Ávila Esquivel Tania , Aguiar Moya José Pablo
Published: August 2021

Se reconoce la necesidad de conocer los deterioros típicos de los pavimentos rígidos en Costa Rica, ya que no existen técnicas de diseño ni información a nivel constructivo que tomen en cuenta las variables climatológicas ni de tránsito del país. Con el objetivo de complementar la información existente, se propone una evaluación para determinar los deterioros típicos de los pavimentos rígidos en Costa Rica.

La evaluación de los pavimentos rígidos se basó en una auscultación visual y en un levantamiento automático mediante el Geo 3D. Inicialmente, se realizó el levantamiento de los deterioros de cada uno de los siete proyectos, los cuales se utilizaron para calcular el PCI (del inglés Pavement Condition Index) de cada uno y determinar los deterioros típicos. Luego, se identificaron las características climatológicas y de tránsito de cada proyecto y se relacionaron con los deterioros. Finalmente, se crearon los modelos iniciales de predicción de deterioros con las relaciones obtenidas.

Se observó que los deterioros típicos de Costa Rica son el daño de sello de junta (21,22 %), desprendimiento de agregados (13,58 %), pulimiento de agregado (13,10 %) y agrietamiento lineal (7,08 %), además los deterioros se relacionan con la precipitación, temperatura y ejes equivalentes. Por lo tanto, se recomienda tomar como base los resultados de esta investigación para futuros modelos de predicción de deterioros.
Error estimates for a fully discrete $\varepsilon-$uniform finite element method on quasi uniform meshes
Authors: ŞENDUR Ali , NATESAN Srinivasan , SINGH Gautam
Published: August 2021

In this article, we analyze a fully discrete $\varepsilon-$uniformly convergent finite element method for singularly perturbed convection-diffusion-reaction boundary-value problems, on piecewise-uniform meshes. Here, we choose $L-$splines as basis functions. We will concentrate on the convergence analysis of the finite element method which employ the discrete $L-$spline basis functions instead of their continuous counterparts. The $L-$splines are approximated on the piecewise-uniform Shishkin mesh inside each element. These approximations are used as basis functions in the frame of Galerkin FEM on a coarse piecewise-uniform mesh to discretize the domain. Further, we determine the amount of error introduced by the discrete $L-$spline basis functions in the overall numerical method, and explore the possibility of recovering the order of convergence that are consistent with the classical order of convergence for the numerical methods using the exact $L-$splines.
m-Pluripotential theory on Riemannian spaces and tropical geometry
Authors: SAHİN Sibel
Published: August 2021

In this study we extend the concepts of $m$-pluripotential theory to the Riemannian superspace formalism. Since in this setting positive supercurrents and tropical varieties are closely related, we try to understand the relative capacity notion with respect to the intersection of tropical hypersurfaces. Moreover, we generalize the classical quasicontinuity result of Cartan to $m$-subharmonic functions of Riemannian spaces and lastly we introduce the indicators of $m$-subharmonic functions and give a geometric characterization of their Newton numbers.

Local abelian Kato-Parshin reciprocity law: A survey
Authors: IKEDA Kazim İlhan , SERBEST Erol
Published: August 2021

Let $K$ denote an $n$-dimensional local field. The aim of this expository paper is to survey the basic arithmetic theory of the $n$-dimensional local field $K$ together with its Milnor $K$-theory and Parshin topological $K$-theory; to review Kato's ramification theory for finite abelian extensions of the $n$-dimensional local field $K$, and to state the local abelian higher-dimensional $K$-theoretic generalization of local abelian class field theory of Hasse, which is developed by Kato and Parshin. The paper is geared toward non-abelian generalization of this theory.
High leverage points and vertical outliers resistant model selection in regression
Authors: SHENDE K. , KASHİD Dattatraya
Published: August 2021

It is necessary to consider only relevant predictor variables for prediction purpose because irrelevant predictors in the regression model will tend to misleading inference. There are so many model selection methods available in the literature; among these, some methods are resistant to vertical outliers, but still, the problem of the presence of vertical outliers and leverage points is not well studied. In this article, we have modified the Sp statistic using the generalized M-estimator for robust model selection in the presence of vertical outliers and high leverage points. The proposed model selection criterion selects only relevant predictor variables by probability one for a large sample size. We found the equivalence of this criterion and the existing Cp and Sp criteria. The superiority of a proposed criterion is demonstrated using simulated and real data.
Translation Discourse 4.0: Variety of Formats, Genres and Trends
Authors:   Volgograd State University, Novikova Elina , Naumova Anna ,   Volgograd State University
Published: August 2021

The article considers the specific character of modern translation discourse, trends and opportunities of realization in the era of changes and global challenges. The relevance of the article is determined by the need to establish common and distinctive forms of expression and formats of translation discourse. The representative sources of three communicatively active discursive practices constitute the empirical base of the paper: scientific / translation studies translation discourse; professional / industry translation discourse; didactic translation discourse. The textual material of the discourse under consideration is analyzed in order to identify thematic dominants of three subtypes under consideration. The similarities and differences of the topics discussed by the translation community within the framework of the selected discursive practices are determined. Sources of translation discourse in Russian and German linguistic cultures were also involved in the analysis to identify common and distinctive features. The analysis revealed the tendency of the Russian-language translation discourse to be a more profound scientific search and substantiation of translation problems, and, on the contrary, the tendency of the German- and English-language discourses to discuss applied issues. The analyzed subtypes of translation discourse reveal certain unifying features: current challenges reaction rapidity, new phenomena and trends in society. However, these subtypes have translation tools of their own, traditions and formats that shape thematic dominants of each direction of the discourse. Thus, the paper revealed the dynamic nature of the discourse, on the one hand, and its sustainable development, on the other.
Translation of Analytical Articles for Mass Media: Pragmatics of Discourses
Authors:   Volgograd State University, Mityagina Vera , Chemeteva Yuliya ,   Volgograd State University
Published: August 2021

The paper examines the features of analytical articles in the mass media, which appear due to the interaction of different discourses that form a specific genre of media analytics. Using the material of original analytical articles written in English and German, and their published translations, the authors investigate manifestations of such characteristics as hybridity, diffuseness, intertextuality, as well as translation problems that arise during translation. Based on the analysis of scientific works on the issues of genre hybridity and diffuseness in media discourse, the authors clarify the ambiguous interpretation of the concept of diffuseness and define its boundaries with the concept of hybridity. The research also reveals the following forms of intertextuality caused by the interaction of discourses within the genre of analytical article on legal issues: reference to another text in the form of a hyperlink, citation, allusion. The analysis of fragments from analytical articles of media discourse containing manifestations of hybridity, diffuseness, and intertextuality demonstrates that a translator who is dealing with a text with these characteristics should excellently know the terminology of the basic and projective discourse in the original and target language, be aware of the neologization processes in both discourses, master stylistic transformations, and take into account the pragmatic factors caused by the interaction of the discourses.

Published: August 2021

The article explores the features of intralingual translation of texts into easy and plain languages, identifying the necessary competencies of specialists in this field, and identifying opportunities for training translators in easy and plain language. The article aims to identify the main characteristics, peculiarities and areas of application of intralingual translation. The authors describe the field of translation principles and describe the specifics of their application. Current foreign and Russian literature on the subject has been analyzed to define the key research concepts of "translation into easy language" and "translation into plain language". The key characteristics and specificity of the concepts are identified, and the competencies needed to translate texts into easy and plain language are outlined. The study of illustrative material (examples of translating texts into easy Russian), allows to demonstrate the application of individual principles of translation, to identify extralinguistic factors that need to be taken into account in translation. A generalization of the practical experience of training translators in easy and plain language in Germany made it possible to draw conclusions about the possibilities and content of training in this field in Russia. The results of the research can be applied in universities when developing training programs for translators, in public and commercial organizations when creating an accessible environment in easy and plain language for effective communication with their target audience. In addition, the article may be of interest to practicing interlingual translators who are interested in the topic of intralingual translation and would like to enhance their skills in this area.

ABSTRACT: Glanders is an infectious and often lethal zoonotic disease of equines caused by the bacterium, Burkholderia mallei. This condition is characterized by respiratory, lymphatic, and cutaneous lesions. In this study, we monitored the development of clinical symptoms in animals naturally infected with B. mallei across different equine breeds and also isolated and characterized the disease-causing bacteria. We studied two official glanders outbreaks in the state of Alagoas, Brazil. During the outbreaks, we performed clinical and immunological follow-up of the animals, as well as euthanasia and anatomopathological examination. We also collected diagnostic materials for isolative, phenotypic, molecular, and biological testing. We did not observe any clinical patterns of glanders among animals infected with the same strain of B. mallei. Based on our results, we suggest that early diagnosis of infection should be made through highly sensitive and specific immunoassays. In asymptomatic but positive test cases, we confirmed the importance of conducting pathological, microbiological, and molecular examinations.

Resumo Essa pesquisa objetivou analisar a relação entre o Racismo Moderno e o Sexismo Ambivalente utilizando os Valores Humanos como terceira variável que pudesse explicar essa relação, tendo em vista seu poder de predição de fenômenos sociais. A amostra foi composta por 200 participantes distribuídos quase igualmente quanto ao sexo, sendo 101(50,5%) do sexo feminino e 99 (49,5%) do sexo masculino. A média de idade dos respondentes foi de 23 anos (DP = 5,41). Observou-se que o Sexismo Ambivalente e o Racismo Moderno estão correlacionados positivamente como também se relacionam com as subfunções Realização, Interativa e Normativa dos Valores Humanos explicando parcialmente a relação entre o racismo e o sexismo. Concluiu-se que as expressões modernas de racismo e sexismo estão interligadas e que os valores normativos, que visam manter a estabilidade social e tradição, podem desempenhar um papel importante na explicação parcial dessa ligação.

Published: August 2021

Abstract This study aimed to identify the predictive power of the Work Design (WD) variables on Burnout Syndrome (BS). The sample consisted of 300 professionals, 188 from the field of education and 112 from health care. Two instruments were used in this research, a reduced version of the Work Design Questionnaire (WDQ) and the Brazilian version of the Spanish Burnout Syndrome Inventory (SBI). The results showed that in both professional categories, the factors of work design are predictors of the 4 dimensions of BS, especially factors related to social and task characteristics. In the education field, characteristics of knowledge required by work appear as predictors of only psychological exhaustion; and in health care professionals, as predictors of psychological exhaustion and decreased Enthusiasm towards the job. Implications of these findings will be discussed in terms of their applicability in interventions to prevent BS based on work redesign actions.

Published: August 2021

Resumo O Estresse Traumático Secundário caracteriza-se por um conjunto de sintomas e condutas que se manifestam após a exposição indireta ao trauma. Profissionais que cuidam de pessoas traumatizadas estão susceptíveis ao transtorno. Este estudo examinou a estrutura interna da versão brasileira do Cuestionario de Estrés Traumático Secundario. Participaram 624 profissionais da saúde, acessados on-line. Para realização das análises fatoriais, a amostra foi dividida em dois grupos. Na análise exploratória, foram retidos 12 componentes, com cargas fatoriais entre 0,312 e 0,999. Os resultados da análise confirmatória revelaram que o modelo de doze fatores para 50 itens forneceu o melhor ajuste possível para os dados (RMSEA = 0,044; IC = 10%-90%; CFI = 0,949; TLI = 0,904) e índice de consistência interna geral do modelo foi de 0,91. Esses doze fatores foram distribuídos em quatro escalas (Antecedentes, Síndrome de Trauma Secundário, Personalidade e Consequências), com índices psicométricos relativamente baixos e uma nova organização dos itens das escalas do QETS, em contraste com a versão teórica original do instrumento. Sugere-se que novos estudos psicométricos analisem as escalas do questionário, separadamente, e investiguem outras categorias profissionais, especialmente na área dos serviços de emergências, além de estudos comparativos com amostras clínicas.
Do Advertising Pieces that Portray Brazilian Jeitinho Influence Dishonest Behavior?
Authors: Farias Jéssica , Pilati Ronaldo
Published: August 2021

Abstract This research aimed at investigating whether watching Brazilian advertising pieces that portray a sociocultural behavioral pattern called Brazilian jeitinho would influence participant’s subsequent behavior. One carried out an experiment in which 200 subjects watched and assessed three advertisement pieces. Upon recruitment, participants were informed that they would be taking part in a raffle for a gift card. The number of tickets received per participant was defined by a die-under-cup task. The more tickets they obtained, the higher the chance to receive the prize, providing an incentive to cheat. Afterwards, respondents took part in a task that defined the number of tickets that each would receive to participate in the raffle. Independent variables consisted in the manipulation of priming of jeitinho (video content: jeitinho or neutral) and privacy of the task (with or without privacy). On the other hand, the dependent variable consisted in the result obtained when participants rolled the dices that defined the number of tickets. One found a significant difference between the groups in which privacy was manipulated, indicating that the groups that performed the task aimed at measuring dishonesty with privacy actually tended to report lower values than the ones actually obtained, entailing an effect of contrast. This finding suggests that the implementation of public policies that utilize propaganda that portrays Brazilian jeitinho could reduce engagement in dishonest behavior among Brazilians.

Resumo A Interpersonal Mindfulness in Parenting Scale (IMP) é uma escala de autorrelato que avalia a utilização de habilidades de mindfulness na relação entre pais e filhos. O objetivo deste estudo foi adaptar a IMP para o contexto brasileiro e investigar suas propriedades psicométricas. A adaptação para o português brasileiro foi realizada por psicólogas com características do público-alvo do instrumento. Na etapa de busca por evidências de validade, a amostra foi composta por 221 mães de crianças entre seis e 12 anos. Utilizou-se um questionário de caracterização da amostra, IMP e Questionário de Cinco Facetas de Mindfulness (FFMQ-BR). Os resultados indicaram que os itens apresentaram composição fatorial adequada, e a escala demonstrou consistência interna adequada e se correlacionou de forma positiva com escores gerais de mindfulness (FFMQ-BR). Recomenda-se o uso da IMP em futuras investigações brasileiras que tenham como objetivo a mensuração do nível de mindful parenting em mães.

Abstract Urban solid waste management is a complex system due to the many variables that compose it, which makes it difficult for managers to make decisions. Among the decision-making tools is system dynamics. To identify the gaps between the literature and the studies about urban solid waste management by using system dynamics method, a survey of published papers on the subject was made, which were later analyzed using some defined criteria, such as the level of the study, the software used for modeling, the variables included in the model, among others. The research identified that, among the stages of solid waste management, the collection process is still little incorporated in the models, being mentioned in only nine studies analyzed. Besides, the environmental, financial and institutional requirements were not adequately explored in the models. Future research should endeavor to include these elements in the models, which will allow the proposed system to be approximated to the complex reality of solid waste management.
Comparison of artificial neural networks learning methods to evaluate supply chain performance
Authors: Lunardi Antonio Ricardo , Lima Junior Francisco Rodrigues
Published: August 2021

Abstract: The supply chain performance evaluation is a critical activity to continuously improve operations. Literature presents several performance evaluation systems based on multi-criteria methods and artificial intelligence. Among them, the systems based on artificial neural networks (ANN) excel due to their capacity of modeling non-linear relationships between metrics and allowing adaptations to a specific environment by means of historical performance data. These systems’ accuracy depend directly on the adopted training algorithm, and no studies have been found that assess the efficiency of these algorithms when applied to supply chain performance evaluation. In this context, the present study evaluates four ANNs learning methods in order to investigate which one is the most adequate to deal with supply chain evaluation. The algorithms tested were Gradient Descendent Momentum, Levenberg-Marquardt, Quasi-Newton and Scale Conjugate Gradient. The performance metrics were extracted from SCOR®, which is a reference model used worldwide. The random sub-sampling cross-validation method was adopted to find the most adequate topological configuration for each model. A set of 80 topologies was implemented using MATLAB®. The prediction accuracy evaluation was based on the mean square error. For the four level 1 metrics considered, the Levenberg-Marquardt algorithm provided the most precise results. The results of correlation analysis and hypothesis tests reinforce the accuracy of the proposed models. Furthermore, the proposed computational models reached a prediction accuracy higher than previous approaches.

ABSTRACT Grain drying is a common process, due to its need for the maintenance of quality, but it is the activity with the highest energy demand among the postharvest stages. Thus, this study aimed to evaluate the effect of different tempering times on the energy efficiency of drying process and maintenance of cell membrane integrity of maize grains harvested with moisture content at 0.34 ± 0.01 d.b. The grains were dried in an experimental fixed-bed dryer with control of temperature and air flow conditions. The experiment was conducted in a completely randomized design with five tempering times (0, 4, 8, 12 and 16 hours) and four repetitions, where zero corresponds to continuous drying, while the remaining times correspond to the intermittent dryings. The grains were dried at the temperature of 100 ºC and air flow of 15.4 m3 min-1 t-1 until reaching moisture content of 0.16 ± 0.03 d.b. For intermittent drying, the process was interrupted with 0.22 ± 0.02 d.b. and restarted after the tempering time. The increase of tempering time led to reductions in effective drying time, specific energy consumption, electrical conductivity and damage and increase in the drying rate and overall energy efficiency. Intermittent drying reduced the drying time, being 30.25% more efficient than continuous drying.

Resumo A salinidade da água de irrigação, além de afetar o crescimento e o desenvolvimento, pode afetar, também, a nutrição mineral da planta, com problemas de distribuição de assimilados entre os seus órgãos. Em condições de campo foram avaliadas a produção e a partição de fotoassimilados em duas cultivares de bananeira (Musa spp), sob condições de irrigação com água salina (1,66 dS m-1) e não salina (0,31 dS m-1), durante 300 dias após transplantio. Verificou-se diferença na partição de fitomassa entre os diferentes órgãos das plantas no decorrer do tempo de cultivo, não havendo diferença na produção de biomassa de folhas entre as cultivares, até o final do primeiro ciclo da bananeira. Nas plantas irrigadas com água não salina, variou a distribuição de fotoassimilados para o cacho e o rizoma entre as cultivares.

Resumo O reúso de águas de qualidade inferior é um recurso significativo, principalmente para regiões onde há escassez de água, como é no Nordeste do Brasil e, especificamente, no Estado de Sergipe. Entretanto os efluentes de águas residuárias tratadas destinadas à reutilização devem conter qualidade de forma a não comprometer a saúde do homem nem o meio ambiente. Assim, com este trabalho, objetivou-se obter as características físico-químicas, bacteriológicas e parasitológicas do efluente da Estação de Tratamento de Esgotos (ETE) Rosa Elze, localizada em São Cristóvão, SE, e avaliar sua eficiência. A ETE é constituída de cinco lagoas de estabilização em série: duas lagoas facultativas, seguidas de três lagoas de maturação. Os resultados da caracterização foram satisfatórios, visto que a qualidade do sistema de tratamento possibilita a reutilização do efluente para diversos fins, apresentando ausência de parasitas e média geométrica de coliformes termotolerantes de 480 NMP por 100mL, atendendo às diretrizes da Organização Mundial da Saúde (OMS).
