Associativismo e Percepção do Mercado de Trabalho: uma amostra desta relação entre fisioterapeutas
Authors: Tommaso Maria Cristina De Carvalho , Silva Elidiane Aparecida da , Poloniato Gildelice Stival 
Published: April 2021

Este artigo pretende identificar o grau de associativismo entre fisioterapeutas e a percepção do mercado de trabalho na região sulfluminense para estes profissionais. Para FREIDSON (1994) o grau de associativismo reflete uma categoria organizada, que controla seu trabalho e quem a ele pode se credenciar. Este estudo mostra como fisioterapeutas percebem que o aumento do número de profissionais repercute-se no mercado de trabalho, o médio grau de associativismo entre os entrevistados, o grau de satisfação com os órgãos que os representam e suas expectativas para mercado de trabalho na região em que estão. A pesquisa aponta ainda, que as profissões mais antigas são modelo de profissionalismo. Enquanto isso, estudos de orientação de escolha profissional revelam a importância do comportamento dos profissionais na formação da identidade profissional. Portanto, de que forma estes sentimentos norteiam comportamentos e podem influenciar jovens que pretendem ingressar ou ingressaram recentemente na profissão.

Published: April 2021

Com o advento das novas biotecnologias de reprodução, passamos a conviver com intensas turbulências no que se refere ao conceito de vida humana. Tais tecnologias parecem produzir um mundo bastante vertiginoso para olhares habituados a conceber a representação de humano como sendo uma fronteira natural. Essas perspectivas parecem ancoradas em uma concepção de tecnociência e humanidade como polaridades estanques. Na atualidade, nos deparamos com uma constante mistura entre aquilo que entendemos por humanidade e não-humanidade. Questões como a infertilidade, a reprodução medicamente assistida, a clonagem e principalmente as pesquisas com células embrionárias apontam para a reprodução e condição humanas cada vez mais imbricadas com o artifício. No presente trabalho, abordamos tal cenário a partir do pensamento de Bruno Latour. Em sua teoria das Redes Sociotécnicas, todo e qualquer fato sólido depende de um processo bastante conectivo, onde humanos e não-humanos o colocam em circulação. O foco se volta para a potência de intensas traduções. Com o conceito “vida humana” não é diferente. A partir de lentes híbridas nos debruçamos sobre uma atualidade de intensa controvérsia, onde a natureza do que chamamos humano parece estar em jogo em meio a uma diversidade de mediações. Com o intuito de estudarmos a dinâmica conectiva de tais controvérsias a envolver as novas biotecnologias da reprodução, objetivamos as diferentes traduções da vida humana feitas por múltiplos actantes no controvertido tema. Analisamos alguns periódicos de grande visibilidade e influência no Brasil. Nosso recorte temporal foi limitado entre 2007 e 2008 devido ao grande dinamismo na área de discussão.

Actualmente, los alumnos con altas capacidades intelectuales parecen no estar adecuadamente identificados ni atendidos en los centros educativos, lo cual se ve agravado por la deficiente formación del profesorado. El objetivo de esta investigación fue analizar la relación entre la formación docente y la experiencia en materia de altas capacidades con los conocimientos del profesorado en torno a este tipo de alumnos. Para ello se siguió un estudio por encuesta con docentes españoles de Educación Secundaria (n = 637), quienes cumplimentaron el Cuestionario de Percepción del Profesorado sobre el Alumnado con Altas Capacidades. Los resultados más destacados indicaron que el 57.35% de los participantes que habían recibido formación sobre necesidades específicas de apoyo educativo afirmó saber cuáles eran las principales necesidades de los alumnos con altas capacidades, mientras que de aquellos que no se habían formado previamente solamente contestó afirmativamente el 19.16% (ɸ = .391; sig. = .000). El 61.97% del profesorado que tenía experiencia previa en esta materia y 66.82% de aquellos que no la tenían señalaron que necesitan tener más formación específica al respecto (V = .263; sig. = .000). Los resultados de este estudio ponen de relieve la necesidad de mejorar la formación sobre este tema en la preparación inicial y continua del profesorado.
Currently, gifted students seem not to be adequately identified or cared for in schools, being aggravated by poor teacher education. The aim of this research was to analyze the relationship between teacher education and high capacity experience with teachers’ knowledge about this type of students. For these reasons, a survey study was followed with Spanish teachers of Secondary Education (n = 637), who completed the Teacher Perception about Gifted Students Questionnaire. The most outstanding results indicated that 57.35% of the participants who had received training on specific educational support needs stated that they knew the main needs of gifted students, meanwhile those who had not previously trained only answered affirmatively the 19.16% (ɸ = .391; sig. = .000). 61.97% of teachers who had previous experience in this area and 66.82% of those who did not it indicated that they need to have more specific training in this regard (V = .263; sig. = .000). The results of this study highlight the need to improve training on this topic in the initial and continuous teacher education.

Published: April 2021

En la Educación Superior se requiere superar un número considerable de objetivos y tareas para alcanzar las competencias de propias de cada titulación y no todo el alumnado logra este objetivo con rigor académico, siendo el plagio un recurso utilizado en la realización de los trabajos académicos, de ahí la importancia de este fenómeno y la necesidad de tomar medidas que puedan erradicar este tipo de acciones.
En este trabajo, utilizando una metodología cualitativa y a partir de las respuestas de alumnado universitario a la pregunta sobre cómo evitar el plagio se intentó comprender la importancia que los/as estudiantes otorgan al plagio y como lo conceptualizan, a partir del análisis e interpretación de las respuestas a: qué importancia tiene el proceso formativo en citación para ellos/as, quién debe ser el responsable de esa formación, dónde y cuándo se han de realizar esas acciones formativas, cómo debe desarrollarse el proceso formativo y motivos por qué motivos esta formación es imprescindible en el haber del alumnado.
Los resultados indican que el alumnado considera que una buena formación en citación se convierte en una herramienta clave de la que se debe hacer uso para evitar el plagio en las aulas universitarias.
In higher education, a considerable number of objectives and tasks need to be exceeded in order to achieve the competences of each degree and not all students achieve this goal with academic rigor, being Plagiarism a resource used in academic work, hence the importance of this phenomenon and the need to take measures that can eradicate this type of action. In this paper, using a qualitative methodology and based on the answers of university students to the question on how to avoid plagiarism, an attempt was made to understand the importance that students attach to plagiarism and how they conceptualize it, from the analysis and interpretation of the answers to: the importance of the training process in citation for them, who should be responsible for that training, where and when such training actions should be carried out, how the training process should be developed and the reasons why this training is essential to the students' lives. The results indicate that students consider that a good training in citation becomes a key tool that should be used to avoid plagiarism in university classrooms.

Published: April 2021

La presente investigación analiza el rol del docente, en el contexto de educación superior, considerando los cambios acontecidos por la contingencia de la enfermedad Covid-19, la cual obligó a proseguir el proceso educativo de forma virtual en todo el mundo. El contexto del estudio se circunscribe en dos universidades públicas latinoamericanas ubicadas en México y Costa Rica; la investigación se desarrolla desde la metodología de la Teoría Fundamentada, integrando la entrevista en profundidad como técnica de recogida de información. El análisis de los datos se basa en el método comparativo constante, considerando el primer momento como descriptivo, el cual permite la codificación abierta y en el segundo momento, el relacional, que permite la codificación axial y selectiva generando una matriz de codificación. Los principales hallazgos explican el rol del docente en procura de responder a las urgentes medidas adoptadas por las instituciones educativas, en la que el educador debe enmarcar el proceso educativo desde una virtualidad total para el desarrollo de los contenidos.
The present investigation analyzes the role of the teacher, in the context of higher education, considering the changes occurred by the contingency of the Covid-19 disease, which forced to continue the educational process virtually throughout the world. The context of the study is circumscribed in two Latin American public universities located in Mexico and Costa Rica; The research is developed from the methodology of the grounded theory, integrating in-depth interview as a technique for collecting information. The data analysis is based on the constant comparative method, considering the first moment as descriptive, which allows open coding and the second, relational, which allows selective and axial coding, generating a coding matrix. The main findings seek to explain the role of the teacher in trying to respond to the urgent measures of educational institutions, in which the teacher must be framed in the educational process from a total virtuality for the development of content.

Published: April 2021

En este artículo analizamos algunas razones básicas que explicarían las dificultades que el profesorado y los centros de Primaria han tenido para adaptarse a los cambios producidos por la pandemia. Para ello, nos basaremos en los resultados de dos investigaciones del grupo Stellae (USC). De la primera, utilizaremos los datos de las entrevistas a docentes de las Facultades de la USC que imparten la titulación de Magisterio, recogiendo sus percepciones sobre la construcción del conocimiento y la cultura profesional. De la segunda, usaremos los resultados de las entrevistas a un grupo de profesores especialistas en TIC, junto con las entrevistas realizadas a docentes de dos centros seleccionados por sus buenas prácticas, analizando sus percepciones sobre el uso escolar de las TIC y los Materiales Didácticos Digitales. Terminaremos con un breve análisis de cómo han de cambiar los procesos de formación docente, para hacer frente a las incertidumbres y nuevos desafíos que afronta la escuela en tiempos de crisis.
In this paper, we analyzed some reasons that would explain the difficulties that teachers and primary schools had in adapting to the changes produced by the COVID 19 pandemic. For this, we start from the results of two investigations by the Stellae group (USC). From the first, we will use the data from the interviews with professors from the Faculties of the USC that confer the degree of Teaching, collecting their perceptions about the construction of knowledge and professional culture. From the second, we will use the results of interviews with a group of ICT teachers, together with interviews and observations made with teachers from two centers selected for their good practices, analyzing their perceptions about the school use of ICT and Materials Digital didactics. We will end with a brief analysis of how teacher training processes must change, in order to deal with the uncertainties and new challenges that the school faces in times of crisis.
A Density-Based Method for the Identification of Non-Disjoint Clusters With Arbitrary and Non-Spherical Shapes
Authors: Ben Ncir Chiheb Eddine 
Published: April 2021

Overlapping clustering is an important challenge in unsupervised learning applications while it allows for each data object to belong to more than one group. Several clustering methods were proposed to deal with this requirement by using several usual clustering approaches. Although the ability of these methods to detect non-disjoint partitioning, they fail when data contain groups with arbitrary and non-spherical shapes. We propose in this work a new density based overlapping clustering method, referred to as OC-DD, which is able to detect overlapping clusters even having non-spherical and complex shapes. The proposed method is based on the density and distances to detect dense regions in data while allowing for some data objects to belong to more than one group.Experiments performed on articial and real multi-labeled datasets have shown the effectiveness of the proposed method compared to the existing ones.
A novel deep autoencoder based survival analysis approach for microarray dataset
Authors: Torkey Hanaa , Atlam Mostafa , El-Fishawy Nawal , Salem Hanaa 
Published: April 2021

BackgroundBreast cancer is one of the major causes of mortality globally. Therefore, different Machine Learning (ML) techniques were deployed for computing survival and diagnosis. Survival analysis methods are used to compute survival probability and the most important factors affecting that probability. Most survival analysis methods are used to deal with clinical features (up to hundreds), hence applying survival analysis methods like cox regression on RNAseq microarray data with many features (up to thousands) is considered a major challenge.MethodsIn this paper, a novel approach applying autoencoder to reduce the number of features is proposed. Our approach works on features reconstruction, and removal of noise within the data and features with zero variance across the samples, which facilitates extraction of features with the highest variances (across the samples) that most influence the survival probabilities. Then, it estimates the survival probability for each patient by applying random survival forests and cox regression. Applying the autoencoder on thousands of features takes a long time, thus our model is applied to the Graphical Processing Unit (GPU) in order to speed up the process. Finally, the model is evaluated and compared with the existing models on three different datasets in terms of run time, concordance index, and calibration curve, and the most related genes to survival are discovered. Finally, the biological pathways and GO molecular functions are analyzed for these significant genes.ResultsWe fine-tuned our autoencoder model on RNA-seq data of three datasets to train the weights in our survival prediction model, then using different samples in each dataset for testing the model. The results show that the proposed AutoCox and AutoRandom algorithms based on our feature selection autoencoder approach have better concordance index results comparing the most recent deep learning approaches when applied to each dataset. Each gene resulting from our autoencoder model weight is computed. The weights show the degree of effect for each gene upon the survival probability. For instance, four of the most survival-related experimentally validated genes are on the top of our discovered genes weights list, including PTPRG, MYST1, BG683264, and AK094562 for the breast cancer gene expression dataset. Our approach improves the survival analysis in terms of speeding up the process, enhancing the prediction accuracy, and reducing the error rate in the estimated survival probability.

Published: April 2021

Background
The aim of this study was to compare the effects of 8 weeks resistance training (RT) with two sessions versus four sessions per week under volume load-equated conditions on body composition, maximal strength, and explosive actions performance in recreationally trained men.

Methods
Thirty-five healthy young men participated in the study and were randomly divided into a two sessions per-week RT (RT2, n = 12), four sessions per-week RT (RT4, n = 13) or a control group (CG, n = 10). All subjects were evaluated for thigh, chest and arm circumference, countermovement jump (CMJ), medicine ball throw (MBT), 1-repetition maximum (1RM) leg press, bench press, arm curl, muscular endurance (i.e., 60% of 1RM to failure) for leg press, and bench press at pre, mid (week 4) and post an 8-week training intervention.

Results
A two-way analysis of variance with repeated measures (3 [group] × 3 [time]) revealed that both training groups increased chest and thigh circumferences, strength and explosive actions performance tests in comparison to CG following 8 weeks of training (p = 0.01 to 0.04). Group × time interactions were also noted in 1RM bench press (effects size [ES] = 1.07 vs. 0.89) and arm curl (ES = 1.15 vs. 0.89), with greater gains for RT4 than RT2 (p = 0.03).

Conclusion
RT improved muscle strength, explosive actions performance and markers of muscle size in recreationally trained men; however, four sessions of resistance training per week produced greater gains in muscular strength for the upper body measures (i.e., 1RM bench press and arm curl) when compared to two sessions per week under volume-equated conditions.
