The histone codes for meiosis
Authors: Wang Lina , Xu Zhiliang , Khawar Muhammad Babar , Liu Chao , Li Wei
Published: July 2017

Meiosis is a specialized process that produces haploid gametes from diploid cells by a single round of DNA replication followed by two successive cell divisions. It contains many special events, such as programmed DNA double-strand break (DSB) formation, homologous recombination, crossover formation and resolution. These events are associated with dynamically regulated chromosomal structures, the dynamic transcriptional regulation and chromatin remodeling are mainly modulated by histone modifications, termed ‘histone codes’. The purpose of this review is to summarize the histone codes that are required for meiosis during spermatogenesis and oogenesis, involving meiosis resumption, meiotic asymmetric division and other cellular processes. We not only systematically review the functional roles of histone codes in meiosis but also discuss future trends and perspectives in this field.
MECHANICAL SUTURE IN RECTAL CANCER
Authors: Cheregi Cornel Dragos , Simon Ioan , Fabian Ovidiu , Maghiar Adrian
Published: July 2017

Background and aims. Colorectal cancer is one of the most frequent digestive malignancies, being the third cause of death by cancer, despite early diagnosis and therapeutic progress made over the past years. Standard treatment in these patients is to preserve the anal sphincter with restoration of intestinal function by mechanical colorectal anastomosis or coloanal anastomosis, and to maintain genitourinary function by preservation of hypogastric nerves.Methods. In order to emphasize the importance of this surgical technique in the Fourth Surgical Clinic of the CF Clinical Hospital Cluj-Napoca, we conducted a prospective observational interventional study over a 3-year period (2013-2016) in 165 patients hospitalized for rectal and rectosigmoid adenocarcinoma in various disease stages, who underwent Dixon surgery using the two techniques of manual and mechanical end-to-end anastomosis. For mechanical anastomosis, we used Covidien and Panther circular staplers. The patients were assigned to two groups, group A in which Dixon surgery with manual end-to-end anastomosis was performed (116 patients), and group B in which Dixon surgery with mechanical end-to-end anastomosis was carried out (49 patients).Results. Mechanical anastomosis allowed to restore intestinal continuity following low anterior resection in 21 patients with lower rectal adenocarcinoma compared to 2 patients in whom intestinal continuity was restored by manual anastomosis, with a statistically significant difference (p<0.000001). The double-row mechanical suture technique is associated with a reduced duration of surgery (121.67 minutes for Dixon surgery with mechanical anastomosis, compared to 165.931 minutes for Dixon surgery with manual anastomosis, p<0.0001).Conclusion. The use of circular transanal staplers facilitates end-to-end anastomosis by double-row mechanical suture, allowing to perform low anterior resection in situations when the restoration of intestinal continuity by manual anastomosis is technically not possible, with the aim to preserve the anal sphincter, to restore intestinal function and maintain genitourinary function through preservation of hypogastric nerves.
Análisis de los efectos dispersivos y no lineales de un canal óptico empleando métodos numéricos
Authors: Peralta Sevilla Arturo , Tipán Simbaña Milton , Amaya Fernández Ferney
Published: July 2017

En este documento, presentamos el modelado de un canal de fibra óptica mediante la resolución de la Ecuación No Lineal de Schrödinger (NLSE). Se presentan las dos formas de solución para la NLSE: la forma analítica y la forma numérica empleando el método SSF (Split–Step Fourier Transform). En la simulación se consideran efectos lineales como la dispersión cromática y los efectos no lineales. Uno de los efectos no lineal es el efecto Kerr, del que se derivan los efectos de auto modulación fase (Self Phase Modulation, SPM) y modulación de fase cruzada (Cross Phase Modulation, XPM). Los métodos de solución son empleados para simular y visualizar los efectos de propagación a través de la fibra óptica. Se analizan los efectos de propagación para un escenario de red de acceso óptica con fibra mono–modo estándar (Single Mode Fiber, SMF), con longitudes de fibra de 20 y 40 km y tasas de bits entre 1,25 y 100 Gbps. De otro lado, son presentados los fenómenos no lineales como dispersión estimulada de Raman (Stimulated Raman Scattering, SRS) y dispersión estimulada de Brillouin (Stimulated Brillouin Scattering, SBS). Se presentan las ecuaciones para modelar SRS. Se presentan resultados de simulación de la amplificación Raman en un escenario seleccionado.

Authors: Cárdenas Damián , Escudero Juan , Quizhpi Sebastián , Amaya Pinos Marco
Published: July 2017

Esta investigación propone un diseño de carrocería de bus interprovincial que disminuya los efectos de la energía cinética producidos por una colisión frontal en la estructura del mismo. Esto se logrará basando el estudio en la normativa vigente emitida por el INEN para diseñar una estructura que la apruebe a cabalidad, estableciendo un estudio de campo actual de las estructuras y modificando su parte estructural con elementos de sección tubular. Los análisis computacionales por el método de elementos finitos en software CAE ANSYS© demostrarán la factibilidad de este diseño y un estudio en modelos análogos a escala manifestará físicamente la diferencia entre la estructura propuesta contra una convencional sometida a las mismas condiciones en una colisión frontal.

Recomendaciones para la adquisición y crianza de una mascota
Authors: Mora Castro Gustavo
Published: July 2017

Siempre que se piense en adquirir una mascota deberá pensarse en el tamaño que la
misma tendrá cuando sea un adulto y no en el tamaño del cachorro que se está por
adquirir. Si actuamos de esta manera estaremos previniendo contratiempos como
falta de espacio para que la mascota haga ejercicio y tenga un desarrollo psicológico
normal, falta de presupuesto para la alimentación, falta de tiempo para el cuidado del pelaje, posibles lesiones a los niños causadas por una mascota muy pesada mientras esta jugando.

Fratria: Tratamento parental diferenciado e estados emocionais negativos
Authors: Pinheiro Ana Filipa , Monteiro Fernandes Otí­lia , Carvalho Relva Inês
Published: July 2017

Para compreendermos a dinâmica familiar, temos de conhecer a constituição da família, pois são as características dos seus membros e das relações entre eles que influenciam essa dinâmica, nomeadamente, o número de filhos e as experiências diferenciadas, como a perceção da justiça e as doenças, que cada um deles tiveram e têm. Nesta amostra de 244 adolescentes verificámos que os adolescentes do sexo masculino sentem uma maior diferenciação ao nível do tratamento parental comparativamente aos adolescentes do sexo feminino, e que a depressão se correlaciona positivamente com o tratamento materno diferenciado, tendo este, assim, um contributo significativo para o aparecimento da depressão nos adolescentes. Como o tratamento materno diferenciado parece influenciar o bem-estar emocional dos adolescentes, parece-nos importante que se façam mais investigações de modo a compreender melhor qual o seu impacto e as suas repercussões na vida dos filhos, quer na adolescência, quer na infância.

Pré-hidratação e condicionamento fisiológico de sementes de maracujazeiro amarelo
Authors: Vieira Araujo Maicon Marinho , Fernandes Dayane Ávila , Jardini Debora Curado , Camili Elisangela Clarete
Published: July 2017

Apesar de poucas informações a respeito da germinação de sementes de passifloráceas, é unânime a afirmativa de que o início e o término da germinação das sementes dessas plantas ocorrem de forma irregular. A alternativa viável para uniformizar a geminação tem sido o emprego de polietilenoglicol (PEG 6000). Assim, objetivou-se com o presente trabalho avaliar a germinação de sementes de maracujá-amarelo em resposta ao condicionamento osmótico com PEG 6000 e ao tratamento térmico. O delineamento experimental adotado foi inteiramente casualizado, em esquema fatorial (5 x 5) +1, com 4 repetições. Os fatores consistiram de cinco tempos de pré-hidratação das sementes (10, 15, 20, 25 e 30 minutos) e imersão em solução de PEG 6000 (-1,2 MPa) por 0, 12, 24, 36 e 48 h, mais um tratamento testemunha. A germinação foi avaliada por meio da porcentagem de sementes germinadas, deterioradas, duras e/ou mortas e com fungos, índice de velocidade de emergência e tempo médio de emergência. A pré-hidratação com água a 40 ºC e a imersão em PEG 6000 influenciaram positivamente a taxa de germinação, IVE e TME, das sementes de maracujá-amarelo. A pré-hidratação de sementes de maracujá-amarelo com água aquecida a 40 ºC por 20 minutos combinada à imersão em PEG 6000 por 36 h resulta em maior uniformidade de plântulas e 90% de germinação.

Published: July 2017

A mudança na colheita da cana-de-açúcar vem causando alterações no seu manejo devido à permanência da palhada sobre o solo, que impõe uma barreira física que pode alterar a qualidade e a quantidade de radiação solar que chega ao solo, modificando a fitossociologia das plantas daninhas. Assim, objetivou-se com este trabalho avaliar a qualidade de luz na germinação de sementes e níveis de palhada, sobre a emergência e desenvolvimento inicial de três espécies daninhas do gênero Euphorbia. Sementes de E. heterophylla, E. hyssopifolia e E. hirta foram submetidas à germinação sob luz branca, vermelha, vermelha extrema e escuro, à temperatura de 20-30 °C, em laboratório, e semeadas sob 0, 5, 10, 15, 20 e 25 t ha-1 de palhada, em casa de vegetação. No primeiro ensaio, foram avaliadas a porcentagem e o índice de velocidade de germinação (IVG) e a massa seca das plântulas, e no segundo, porcentagem de emergência, cobertura do solo, altura e massa seca de plantas. As sementes de todas as espécies germinaram em todas as condições luminosas, entretanto, E. heterophylla apresentou maior geminação e IVG sob luz vermelha, enquanto que E. hirta e E. hyssopifolia apresentaram sob luz branca. Sob palhada, E. heterophylla teve o melhor desempenho, suportando duas vezes mais palhada que E. hyssopifolia e quatro vezes mais que E. hirta, para haver redução de 50% de emergência e desenvolvimento das plantas. A presença da palhada não controla E. heterophylla, por outro lado suprime as espécies E. hyssopifolia e E. hirta. As três espécies estudadas são indiferentes à luz.

Authors: Hanisch Ana Lúcia , Balbinot Jr. Alvadi Antonio , Vogt Gilcimar Adriano
Published: July 2017

Bactérias do gênero Azospirillum podem fixar nitrogênio (N) atmosférico e promover o crescimento vegetal, contribuindo na nutrição das plantas. Com base nesse pressuposto, objetivou-se com o presente trabalho avaliar o efeito de doses de nitrogênio no desempenho de uma pastagem de Urochloa brizantha cv. Marandu na presença ou ausência de inoculação com Azospirillum brasilense. O experimento foi conduzido em delineamento em blocos completamente casualizados, em esquema fatorial (2 x 4) e quatro repetições. O primeiro fator correspondeu à presença ou ausência de inoculação de sementes com Azospirillum brasilense, e o segundo a quatro doses de N em cobertura (0; 50;100 e 150 kg ha-1 por ano). O período de avaliação foi de novembro de 2012 a abril de 2013 e de novembro de 2013 a abril de 2014, sendo realizados quatro cortes na pastagem, em cada ano. A inoculação de sementes de U. brizantha cv. Marandu com A. brasilense não alterou a disponibilidade e a composição química da forragem. Não houve influência da interação entre a inoculação das sementes com A. brasilense e doses de N mineral em cobertura sobre a disponibilidade e a composição química da forragem de U. brizantha cv. Marandu em nenhum ano de avaliação. A adubação nitrogenada em cobertura aumentou a produção de forragem de U. brizantha cv. Marandu, somente no primeiro ano de avaliação e não afetou sua composição química nos dois anos de avaliação. O N mineral não afeta a associação entre Azospirillum brasilense e Urochloa brizantha.

Published: July 2017

Dentistry is one among the most challenging and stressful fields. Research evidence that a person’s emotional intelligence (EI) influences their educational and occupational performance is increasing. Hence, our aim was to assess the influence of trait emotional intelligence on the academic performance of dental undergraduates. A cross sectional study was done on 462 students of 2nd, 3rd, 4th years and interns from five dental colleges using simple random sampling. Trait emotional intelligence was measured using the shorter version of Trait Emotional Intelligence Questionnaire (TEIQUE-SF), and academic performance was assessed using score obtained in the university examination. The mean EI was found to be 101.01. Majority of them agreed that in-spite of finding it difficult to regulate emotions; they could deal effectively with people. Almost 59% of them agreed that they could deal with stress and 66% were able to control their emotions. There was also a significant difference between EI and age (p=0.000). Emotional Intelligence had a significant association with the academic performance of the students.

Las bandas juveniles en la sociedad contemporánea: marginalidad y resistencia
Youth gangs in contemporary society: marginalisation and resistance
Authors: Giliberti Luca
Published: July 2017

RESUMEN El artículo explora el universo de los grupos juveniles hijos de la marginalidad –denominados bandas– en los barrios de las periferias globales, reflexionando sobre el fenómeno en la época contemporánea. Se presentan estos grupos compuestos por los hijos del subproletariado metropolitano, caracterizados mayoritariamente por su condición inmigrante, y conformados por elementos tanto globales como locales. Se discute la imagen dominante socialmente construida sobre estos colectivos, que declara una visión estigmatizadora, cada vez más con la crisis. Al mismo tiempo, se remarca cómo estos grupos brindan a los individuos una pertenencia y una identidad a la cual poder hacer referencia. También, las bandas pueden verse como grupos de resistencia –aunque ambiguos y contradictorios– a la violencia estructural que padecen. El cuadro interpretativo que se presenta en el artículo es fruto de diferentes investigaciones etnográficas del autor sobre los grupos juveniles marginalizados –en particular sobre las bandas latinas en el territorio catalán– realizadas en los últimos diez años.   PALABRAS CLAVE: bandas, nación, síntomas, estigma, resistencia   ABSTRACT The article explores the world of so-called youth gangs from suburban neighbourhoods, children of marginalisation, and reflects upon this phenomenon in the contemporary context. These groups are primarily composed of children of the metropolitan sub-proletariat, primarily characterised by their immigrant status and defined by global as well as local elements. The dominant image of these groups constructed by society is discussed as being stigmatising, even more so during the recent financial crisis. At the same time, these groups provide a sense of belonging and an identity to which individual members can refer. Furthermore, despite their ambiguity and contradictions, gangs can also be seen as groups of resistance against the structural violence that they endure. The interpretative framework of the article is based on various ethnographic research studies that the author conducted over the last ten years on marginalized youth groups, bandas latinas [Latino gangs ] in Catalonia in particular.

La enfermería femenina del área de medicina del Hospital de las Cinco Llagas de Sevilla en los siglos XVI al XVIII
Female Nurses in the Medicine Area of the Hospital de las Cinco Llagas in Seville in the XVI and XVIII Centuries
Authors: Rivasplata Varillas Paula Ermila
Published: July 2017

RESUMEN En el Antiguo Régimen ibérico, los hospitales fueron de las pocas instituciones que se caracterizaron por la especialización del trabajo femenino, convirtiéndose en lugares de refugio y de opción de vida para muchas mujeres que demostraban dedicación absoluta al hospital. En este contexto, la hipótesis planteada es que en un hospital regido por religiosos como fue el de las Cinco Llagas de Sevilla, se esquematizó el trabajo femenino del cuidado, caracterizado por el control, la prohibición y la separación de sexos. De tal manera que creó un reducto cerrado de la visibilidad pública de las labores realizadas por las enfermeras en una institución amparada por la Iglesia. La metodología utilizada fue la heurística y la hermenéutica de las fuentes primarias consultadas en el Archivo de la Diputación Provincial de Sevilla.   PALABRAS CLAVE: enfermeras, mujeres, Antiguo Régimen, Hospital de las Cinco Llagas, Sevilla   ABSTRACT In the Iberian Old Regime, hospitals were among the few institutions that were characterized by specialization of women’s work where the female nurse could develop freely, and they became places of refuge and life choice for many women who showed absolute dedication to the hospital. In this context, the raised hypothesis is that, in a hospital governed by religious as it was that of las Cinco Llagas of Seville, it was outlined the feminine work of the care, characterized by the control, the prohibition and the separation of sexes. In such a way that this hospital sheltered ill women and needed other women to work both in domestic and medical activities, creating a place closed to public visibility of the job done by these women in an institution protected by the church. The methodology used was heuristics and hermeneutics of primary sources consulted in the Archivo de la Diputación Provincial of Seville.   KEY WORDS: nurses, women, Old Regime, Hospital de las Cinco Llagas, Sevilla

Las vestimentas y la cultura de la moda asociada a su porte evolucionaron durante la Edad Moderna, constituyéndose en iconos capitales para comprender los cambios sociales y de civilización experimentados en la Castilla interior. El examen de los tradicionalismos simbólicos y/o de los intensos debates críticos ilustrados sobre el uso de los atuendos permite valorar mucho mejor la trascendencia que el vestido representaba en el universo mental de las poblaciones urbanas y rurales de Antiguo Régimen. Cuestiones como el lujo y la apariencia, el reconocimiento externo o la uniformización indumentaria resultan fundamentales a este respecto, tanto desde un enfoque de vida cotidiana, de cultura material o de consumo familiar.PALABRAS CLAVE: Castilla, vestimenta, moda, apariencias, modernidad.ABSTRACTClothing and fashion culture associated with good appearance evolved during Modernity to become capital icons of the social and civilization changes present in the interior of Castile and vital to their understanding. The examination of symbolic traditionalisms and/or the intense and enlightened critical debates on the use of attire allows for a better assessment of the transcendence that clothing represented in the mental universe of the urban and rural populations of the ancien régime. Issues such as luxury and appearance, external recognition and uniformization are critical in this regard from everyday life, material culture or family consumption perspectives.KEY WORDS: Castile, clothing, fashion, appearances, modernity.

Se ha realizado un estudio exploratorio con un tema transversal: las unidades didácticas de la Edad Moderna en 2º de ESO en España y 4º de Collège en Francia. Este estudio ha analizado de una forma comparativa tanto los contenidos sustantivos que presentan los manuales (qué conocimientos históricos se proponen en estos materiales educativos), como los contenidos estratégicos (cómo se presentan esos conocimientos y qué tipo de habilidades cognitivas se le exige al alumnado). Los datos muestran resultados dispares. Por un lado la nación (su origen y consolidación) sigue siendo el principal sujeto histórico en los manuales. Pero existe una gran diferencia en las competencias históricas propuestas al alumnado en España (con un aprendizaje más memorístico) y en Francia (con un análisis más profundo de las fuentes históricas).PALABRAS CLAVE: enseñanza de la historia, narrativa nacional, libros de texto,pensamiento histórico, competencias educativas.ABSTRACTThe main objective of this paper is to look into the historical narratives and the competencies developed in secondary education history textbooks by comparing thecontents and historical thinking on the Early Modern period proposed by French and Spanish textbooks.

La historia de las relaciones entre Rumanía y España tiene en los libros de viajes delsiglo XIX una importante fuente histórica y literaria. Los escritos de diplomáticos, militares, políticos o literarios han resultado de particular importancia para evitar algunos tópicos y estereotipos existentes en el conocimiento de otros países. Durante la primera mitad del siglo XIX muy pocos viajeros rumanos llegaron a la periferia de Europa, donde se encontraba la península ibérica, y fueron muchos menos los que dejaron algún testimonio escrito de sus viajes. Mihail Kogalniceanu (1817-1891), un estadista liberal rumano, que llegó a ser primer ministro y ministro de Asuntos Exteriores en la década de 1860, tuvo la oportunidad de visitar España entre 1846 y 1847 y dejarnos el testimonio de su mirada en sus Notes sur l’Espagne, contribuyendo al conocimiento de la historia, las tradiciones y la cultura españolas para las élites y la sociedad rumana.PALABRAS CLAVE: Mihail Kogălniceanu, libros de viajes, Notes sur l’Espagne, siglo XIX.ABSTRACTThe history of relations between Romania and Spain has an important historical andliterary source in the travel books of the nineteenth century.

Los periódicos obreros se crearon como un mecanismo de defensa ante el control ideológico que la burguesía desempeñó sobre la mayoría social. Fueron también una herramienta de concienciación ideológica y la punta de lanza de las organizaciones obreras en ladifusión del modelo de sociedad que querían construir.Guadalajara no fue una excepción a este hecho y, sobre todo, durante el primer tercio del siglo XX se produjo un importante desarrollo de estas publicaciones. En el presente artículo vamos a analizar las principales cabeceras obreras de Guadalajara desde 1882, año en el que apareció el primer periódico obrero, hasta el inicio de la guerra civil española. Con el estudio de estas publicaciones trataremos de analizar el papel que jugaron dichos periódicos en una sociedad como la de Guadalajara, además de ver qué influencia tenían entre la propia clase obrera y las propias dinámicas que se iban creando con su edición.PALABRAS CLAVE: Guadalajara, movimiento obrero, prensa, escritura, lectura.ABSTRACTOver the end of the 19th century and the beginning of the 20th, the labour movement created and strengthened its political and union organizations and one of its main means of communication was developed: the workers’ press. Working-class newspapers were created as a defence mechanism against the ideological control of the bourgeoisie over the social majority. They were also a key element in raising ideological awareness and the spearhead of workers’ organizations to disseminate the model of society they wanted to build.Guadalajara was no exception in this regard and the first three decades of the 20th century there witnessed an important increase in the number of these publications. This paper analyzes the main Guadalajara workers’ newspapers from 1882, when the first of them appeared, to the beginning of the Spanish Civil War. Our aim is to study the role that these newspapers played in a society such as Guadalajara, to examine their influence on the working class and to look into the dynamics that were gradually created with their publishing.KEY WORDS: Guadalajara, labour movement, press, writing, reading.
La tarjeta postal como documento histórico: una aproximación visual a la Primera Guerra Mundial
The postcard as a historical document: a visual approach to the First World War
Authors: López Torán José Manuel
Published: July 2017

Desde que en 1869 aparecieran las primeras tarjetas postales ilustradas, estas pequeñas cartulinas han logrado convertirse con el tiempo en testimonio del pasado, en documentos históricos de primer orden que cubren un espectro temporal de casi siglo y medio de nuestra historia y en objetos culturales que simbolizan el desarrollo de toda una época y que abarcan los principales acontecimientos más recientes y muchos de los aspectos de la vida diaria. La Primera Guerra Mundial, por su magnitud y sus consecuencias, se ha posicionado como uno de los episodios más importantes de nuestra historia reciente y, sin lugar a dudas, las artes gráficas se convirtieron en un mecanismo de expresión de los acontecimientos que iban ocurriendo, de ahí la enorme difusión a través de fotografías, carteles, grabados y, por supuesto, de tarjetas postales, que tan populares se hicieron durante aquellos años. A través del análisis de más de diez mil postales, consultadas en su mayoría a través de las páginas web de los principales centros de documentación a nivel internacional, se pretende realizar un acercamiento a este episodio histórico, a la vez que poner en valor el papel que jugaron en el propio desarrollo del conflicto, al convertirse en uno de los principales medios utilizados en la difusión y propaganda de la contienda.PALABRAS CLAVE: Primera Guerra Mundial, tarjeta postal, historia de las emociones, propaganda, fotografía.ABSTRACTSince the first picture postcards appeared in 1869, these small cards have managed over time to become a testimony of the past, a top-notch historical document which covers a time spectrum of close to a century of our history, and a cultural object which symbolizes the development of an era that covers the major recent events and many aspects of daily life. The First World War, in its magnitude and its consequences, has been one of those historical chapters of our recent historyand the graphic arts became a mechanism for the expression of the events that happened during it. It was during the war that the popularity of photographs, posters, prints and, of course, postcards became more widespread. Through the analysis of more than 10000 postcards, consulted mostly through the webpages of the most important international documentation centers, we seek to take a close look at this historical development and to focus on the role they played in the conflict as they became one of the main media used in the dissemination and propaganda of the battle.KEY WORDS: First World War, postcard, history of emotions, propaganda, photography.

The Impact Of Metacognitive, Cognitive And Motivational Cultural Intelligence On Behavioral Cultural Intelligence
Authors: Gooden Doreen J. , Creque Carole Ann , Chin-Loy Claudette
Published: July 2017

This study investigates the impact of Metacognitive, Cognitive, and Motivational Cultural Intelligence (CQ) on Behavioral Cultural Intelligence (CQ).  In particular, we examine whether cognitive capabilities influence actions and behavior. The results show that 28.4% of the variability in behavioral CQ is explained by metacognitive CQ, cognitive CQ and motivational CQ. Further analysis was done to determine how each of these three dimensions impacts on behavioral CQ.  Results show that only metacognitive and motivational CQ influence behavioral CQ.
Figurações dos indígenas em À margem da história
Authors: Volker Camila Bylaardt
Published: July 2017

O artigo aborda a figuração do indígena em À Margem da História, de Euclides da Cunha, especificamente nos artigos “Os Caucheros” e “Brasileiros”. Partindo de um breve apanhado de narrativas que deixam de figurar os indígenas entre as suas personagens, o texto analisa como a argumentação euclidiana endossa uma perspectiva de extermínio e extinção inexorável dos povos indígenas.

Inicialmente foi feita uma pesquisa bibliográfica com o objetivo de discutir as contribuições do modelo de gestão social para o fortalecimento da proposta dos conselhos escolares como espaço de vivências democráticas. Em seguida, foi realizado um estudo de caso sobre a regulamentação do Conselho Escolar no Sistema de Ensino de Brumadinho, Minas Gerais. Os principais resultados alcançados demonstraram que o modelo de gestão social possui características como diálogo, participação, democratização e emancipação, que podem contribuir para o fortalecimento do CE como espaço democrático.
Use of the Genre-Based Approach to Teach Expository Essays to English Pedagogy Students
Authors: Gómez Burgos Eric
Published: July 2017

The following article reports the results of an action research project conducted in a public university in Chile. The project consisted of exposing ten undergraduate students from an English pedagogy program to a genre-based approach to writing expository essays. During eight weeks the three stages of the genre-based approach, namely: deconstruction, joint construction, and individual construction, were adapted and developed with the participants. Results gave evidence that a genre-based approach to teaching expository essays is effective in this context because after the application of the action research project, the students’ compositions improved in comparison to the participants’ pre-intervention essays.

Proctoring to improve teaching practice
Authors: Brouwer Natasa , Heck André , Smit Guusje
Published: July 2017

Universities organise digital summative assessments in special assessment computer rooms and they conduct strong restrictions on the resources. This policy assures safety and security of assessments but obstructs authentic problem solving where open resources are needed. A digital assessment room is also not a proper solution when students for some reason cannot attend the assessment on campus. We present three scenarios from the science and mathematics teaching practice at the University of Amsterdam in which we have used proctoring to create the flexibility of online exams that was needed. Online remote proctoring of computer screens on the campus and/or students at home enabled (1) more authentic exams by allowing open resources, (2) use of own laptops (BYOD) in a regular lecture room, (3) off campus online exams as a part of an online programme, for example, at home anywhere in the world. We have shown that proctoring is not just a different way to control students using computers, but that it enabled improvement of the quality of learning processes in which summative assessments are an integral part.
MathTOUCH: Mathematical Input Interface for E-Assessment Systems
Authors: Shirai Shizuka , Fukui Tetsuo
Published: July 2017

In 2012, we developed a new mathematical input interface with Java, named MathTOUCH. The interface facilitates the acceptance of a mathematical expression as input by interactively converting from a colloquial-style mathematical text (string). This input method enables users to input almost any mathematical expression without learning a new language or syntax. However, the user requires a Java-compliant device for mathematical input. In this study, we developed a reconstructed version of MathTOUCH by using JavaScript (HTML5) to enable the use of MathTOUCH across various devices. The result of our evaluation showed that students are able to practice their mathematical work on STACK using the reconstructed MathTOUCH as well as the previous version of MathTOUCH.
