Articulaciones Estéticas para una Espiritualidad Sublime. El paisaje contemporáneo en el arte patagónico a partir de la fotografía y el muralismo
Authors: Enrici Aldo , Romano Cintia , Ciselli Graciela , Ciancia Daniela , Ricardo Damián , Espinosa Martha , Coca Juan Romay
Published: October 2020

El presente escrito conlleva parte de las conclusiones pertenecientes al proyecto interdisciplinar 29A340 “Formas De Comprensión de la Identidad. Paisaje, Arte y Patrimonio Cultural en Patagonia”. Se expondrán características del arte paisajista en hitos sobresalientes. Posteriormente se mencionaran las características del arte contemporáneo en artistas de la Patagonia que tienen en cuenta la presencia del viento como espiritualidad. Se desarrolla para eso el concepto de “espiritualidad sublime”. El mismo está basado en la articulación de los conceptos estéticos de “sublimidad” y “espiritualidad” de impurezas. Los exponentes seleccionados para este caso son teóricos de lo sublime: Longino, Kant, Burke y del principal expositor de la interioridad intelectual del artista: Vasili Kandinski. El desarrollo de los significados de paisaje en el mundo occidental es un proceso de cambio en las tecnologías de percepción y modos de representación. A esto se añaden las relaciones sensitivas con mediación entre el espectador y el espacio cultural y material. La cambiante historicidad del paisaje como de la identidad de la comunidad patagónica son características definitorias de la corriente que sostenemos. Específicamente nos referiremos a obras de dos artistas patagónicos: Mario Baigorria en fotografía y Dolores Morón en Muralismo.
On the rate of convergence for a class of Markovian queues with group services
Authors: Kryukova Anastasia L.
Published: October 2020

There are many queuing systems that accept single arrivals, accumulate them and service only as a group. Examples of such systems exist in various areas of human life, from traffic of transport to processing requests on a computer network. Therefore, our study is actual. In this paper some class of finite Markovian queueing models with single arrivals and group services are studied. We considered the forward Kolmogorov system for corresponding class of Markov chains. The method of obtaining bounds of convergence on the rate via the notion of the logarithmic norm of a linear operator function is not applicable here. This approach gives sharp bounds for the situation of essentially non-negative matrix of the corresponding system, but in our case it does not hold. Here we use the method of differential inequalities to obtaining bounds on the rate of convergence to the limiting characteristics for the class of finite Markovian queueing models. We obtain bounds on the rate of convergence and compute the limiting characteristics for a specific non-stationary model too. Note the results can be successfully applied for modeling complex biological systems with possible single births and deaths of a group of particles.
PROCESSO DE DESENVOLVIMENTO INFANTIL: CRISES, RUPTURAS E TRANSIÇÕES
Authors: Sforni Marta Sueli de Faria , Marega Ágatha Marine Pontes
Published: October 2020

Embora o processo de desenvolvimento humano seja, normalmente, entendido como algo progressivo e harmonioso, autores da Teoria Histórico-Cultural, como Vigotski, Leontiev e Elkonin, apresentam o desenvolvimento infantil como um processo dialético em que as mudanças e transições são feitas revolucionariamente (idades com crises e idades estáveis). Assim, o desenvolvimento é evidenciado em momentos de transição, com a presença de saltos qualitativos, rupturas, crises, que muitas vezes são compreendidos, de forma equivocada, como sintomas negativos. Uma educação cuja finalidade é a promoção do desenvolvimento, necessita conhecer como ocorre esse processo. Neste sentido, este artigo resulta de uma pesquisa bibliográfica que teve por objetivo compreender esses momentos de transição, com a finalidade de poder atuar pedagogicamente nas crises, de modo que esses momentos sejam favoráveis ao desenvolvimento e não limitadores dele. Concluímos que a condução racional do processo de transição no ambiente escolar requer intervenção pedagógica organizada e assistida pelos adultos envolvidos (professores, pedagogos e familiares).

INTERAÇÕES DISCURSIVAS SOBRE A CONTEXTUALIZAÇÃO MATEMÁTICA NA EDUCAÇÃO DE JOVENS E ADULTOS
Authors: Da Silva Neomar Lacerda , De Oliveira Andréia Maria Pereira , Maknamara Marlécio
Published: October 2020

O artigo objetivou problematizar o discurso da contextualização matemática e sua relação com práticas discursivas mobilizadas pelos sujeitos curriculares da Educação de Jovens e Adultos. Para tanto, usamos informações secundárias produzidas por meio de entrevistas com estudantes e professores/as que ensinam matemática nessa modalidade de ensino. Em diálogo com autores (as) do campo da Educação Matemática, operamos com ferramentas teórico-analíticas como discurso e poder-saber na perspectiva pós-crítica de estudos curriculares, sobretudo aqueles que se inspiram nas contribuições de Michel Foucault e colaboradores, para assumir as práticas de numeramento enquanto discursivas, portanto, produtoras de verdades acerca do Ensino de Matemática. A análise sugere que práticas de numeramento que têm lugar na Educação de Jovens e Adultos encontram-se atravessadas por relações de poder-saber, que estabelecem, compreendem e produzem discursos como o da contextualização matemática, engendrados no mecanismo da aplicabilidade, para instituir regimes de verdade que naturalizam a hegemonia da matemática formal (acadêmica e escolar) e o discurso da contextualização, e de como os sujeitos curriculares da Educação de Jovens e Adultos são capturados por esse discurso.

Published: October 2020

O presente artigo objetiva apresentar um estudo caracterizado como estado do conhecimento, analisando as principais discussões e os resultados de pesquisas brasileiras sobre o fenômeno da juvenilização na Educação de Pessoas Jovens e Adultas (EJA). Metodologicamente utilizou-se a pesquisa do tipo bibliográfico no estudo, tal como proposto por Romanowski e Ens (2006), cujo levantamento foi realizado em três bases de dados de relevância para a área educacional, a saber: Catálogo de Teses e Dissertações da CAPES, Biblioteca Digital de Teses e Dissertações (BDTD) e no Grupo de Trabalho de Educação de Pessoas Jovens, Adultas e Idosas da ANPEd (nas reuniões nacionais). Os resultados foram analisados com base nas técnicas de análise de conteúdo estabelecidas por Bardin (1995). As pesquisas identificadas nessas bases de dados foram categorizadas em quatro categorias: Sujeitos; Escolarização e Inclusão, Políticas Públicas e Formação Docente. Com objetivos distintos, todas as pesquisas ressaltaram a importância de considerar os(as) jovens como protagonistas no processo de ensino e aprendizagem e, sobretudo, as discussões apontaram para a necessidade de ouvir os sujeitos jovens para melhor compreender o fenômeno juvenilização, assim como apontar para o fomento de políticas públicas específicas, com o intuito de promover, além da escolarização a inclusão efetiva desses(as) jovens estudantes.

En este trabajo se pudieron analizar las variables más significativas que necesita un sistema solar fotovoltaico para la escuela veredal Campo 45 del municipio de Barrancabermeja, que buscaba como objetivo principal, definir la factibilidad de diseño y dimensionamiento de una potencial instalación de dicho sistema, por lo cual, se requirió una búsqueda exhaustiva de los parámetros climatológicos, un pre-dimensionamiento del sistema en espacio físico libre de instalación, así como, un análisis de costo aproximado para su ejecución. Es importante destacar, que se utilizó una metodología cuantitativa en la que los datos concretos del sistema y de las variables necesarias de su funcionamiento, fueron elementales para realizar una evaluación integral de su posible funcionamiento efectivo en el lugar, por otro lado, se utilizaron varias herramientas web gratuitas como calculadoras solares que permitieron analizar mucho mejor los resultados. Para un mejor acercamiento, se obtuvo de dicho análisis que en la zona se pueden obtener un promedio mensual de 155 kWh/m2, lo que permitiría un aprovechamiento adecuado de energía eléctrica en la escuela si se colocan aproximadamente 5 paneles solares que soporten la demanda de energía eléctrica mensual aproximada de 649 kWh/mes; de igual forma, se realizó una comparación de sistemas a utilizar con paneles que permite ver las diferentes características que pueden ser necesarias a la hora de un buen funcionamiento del sistema, además, se propone un seguimiento en el mantenimiento, teniendo en cuenta las condiciones del lugar. De este proyecto se puede concluir que en la escuela o en la zona de influencia directa, es factible realizar un diseño y una implementación de un sistema solar fotovoltaico que permita el abastecimiento de la necesidad energética de la población.
Designed to allow for Emergence: A Learning Rhizome
Authors: Alexios Brailas
Published: October 2020

“Systems Theory, Psychology, and Social Media” is an Erasmus course offered by the Department of Psychology at Panteion University, Athens, Greece. In this course, Erasmus students co-create a unique and wonderful multi-cultural mosaic, ‘the difference that makes the difference.’ In addition to lecturing, participants are engaged in intensive group work during the weekly face-to-face meetings. Between the face-to-face meetings, participants create blog reflections, narratives, and multimodal artifacts about their in-class lived experience regarding the impact social technologies and artificial intelligence have on living systems. Backed up by the technological infrastructure, a network of interconnected personal blogs, students develop a reflective group ecology of practice. The whole project is informed by complex systems’ epistemology. This virtual research exposition demonstrates the overall process in a non-linear and multimodal way. Implications for rhizomatic learning theory and education are discussed.
Tratamiento de la coledocolitiasis mediante CPRE e instrumentación a través de un tubo en T
Authors: Prieto Ortíz Robin Germán , Duarte Osorio Arturo Iván , García Echeverri Pablo , Ballén Parraga Hernan
Published: October 2020

El tratamiento de la coledocolitiasis ha evolucionado de forma significativa desde que Robert Abbe realizó la primera coledocotomía y la exploración de las vías biliares en Nueva York, en 1889. La colangiopancreatografía retrógrada endoscópica (CPRE), que inicialmente fue un método diagnóstico, ahora solo tiene validez como método terapéutico. En la actualidad, los principales métodos diagnósticos son la colangioresonancia magnética (CRM) y la ultrasonografía endoscópica (USE). El tratamiento de la coledocolitiasis pasó de la técnica quirúrgica abierta -en la que, de forma rutinaria, se realizaba la coledocorrafia sobre un tubo de Kehr o tubo en T- a la endoscópica, mediante el uso de la CPRE, la esfinteroplastia y la instrumentación con balones y canastilla. Hoy en día se dispone de técnicas adicionales como la litotricia mecánica (LM) o extracorpórea, la dilatación con balón (DB) de gran tamaño y el Spyglass®. La técnica laparoscópica se usa desde hace varios años, en diversas partes del mundo, para el tratamiento de la coledocolitiasis. Estudios recientes proponen incluso el cierre primario del colédoco o la coledocoduodenostomía, con lo cual no sería necesaria la utilización del tubo en T. Pero en muchos otros sitios, y por diversas razones, se continúa usando la exploración quirúrgica abierta y el tubo en T, que representa una importante opción en el tratamiento de algunos pacientes. Caso clínico: paciente masculino de 88 años, con coledocolitiasis recidivante, cálculo gigante de difícil manejo endoscópico y sepsis de origen biliar, que requirió drenaje quirúrgico abierto de urgencias. Se realizó una coledocotomía, y se dejó el tubo en T. Posteriormente, se efectuó un tratamiento exitoso conjunto, mediante instrumentación por el tubo en T, por parte de cirugía general, y CPRE, por gastroenterología.

El síndrome de intestino irritable se caracteriza por la existencia de dolor abdominal relacionado con cambios en el ritmo evacuatorio. A pesar de los avances en el conocimiento de su fisiopatología y de la aparición de nuevas formas terapéuticas, los antiespasmódicos se han mantenido en el tiempo como una forma efectiva para el manejo de los síntomas de este síndrome, en especial para el dolor. Así pues, el propósito de esta revisión es la búsqueda de evidencia científica que soporte el uso de antiespasmódicos en el manejo de los síntomas del síndrome de intestino irritable.
Impacto del ambiente en la salud escolar: representaciones sociales del equipo de salud.
Authors: G F Scruzzi , C Rodríguez Junyent , C Tosini , C Bertaina , M C Bustos
Published: October 2020

INTRODUCCIÓN: La salud ambiental comprende aspectos de la salud humana que incluye la calidad de vida y es determinada por condiciones ambientales, físicas, sociales y alimentarias.OBJETIVO: Indagar las representaciones sociales (RS) sobre el impacto del ambiente en la salud de los escolares en el equipo de salud (ES) de dos Centros de Atención Primaria de Salud municipales (CAPS), durante el ciclo 2019 en la ciudad de Córdoba, ArgentinaDISEÑO METODOLÓGICO: La investigación se llevó a cabo desde la perspectiva cualitativa, basada en la teoría fundamentada, con diseño emergente. Se realizaron 13 entrevistas abiertas, a través del método de comparación constante. Los datos fueron validados por triangulación de investigadores.RESULTADOS: A partir de las entrevistas se generaron cinco categorías de análisis. Como ideario de salud emergieron tres grandes dimensiones: física, psicológica y social; la dimensión ambiente no emergió. El ambiente está representado con connotaciones negativas. El ES delega la responsabilidad sobre el ambiente físico al estado y al mercado, mientras que el ambiente social como determinante de la salud de los niños es responsabilidad de la red de interacción más cercana al niño y si bien reconocen que el mercado influye en el ambiente alimentario, la responsabilidad final de la alimentación es considerada un hecho individual.CONCLUSIONES: El ES no incorpora al ambiente como parte del ideario de salud. Al indagar sobre su impacto en la salud de los niños, consideran que está mediado por su padres y cuidadores, excepto en contaminación ambiental, donde el foco está puesto en el rol del estado y el mercado.
Aristotle and Huxley: On happiness
Authors: Radenovic Ljiljana
Published: October 2020

According to Aristotle, one of the necessary, although not sufficient,
conditions for a good and happy life is the possession of virtue. A person
who possesses virtues never wants something that is bad, but only what is
good, and in that way she is free from internal struggle. Such person is
formed through good habits. In Huxley?s dystopia, individuals are shaped by
genetic selection and behavioral conditioning to want only what is good for
the state, its peace and prosperity, and thus to want what is good for
themselves. The goal of this paper is to examine the differences between
Aristotle and Huxley. In the first part of the paper I will discuss
different techniques of character formation in Aristotle and those described
in Huxley?s dystopia. In the second part of the paper, I will address the
question why Huxley?s world does not appeal to us, even though everyone in
it wants exactly what they should want. In the Brave new world Huxley
portrays the world that is built around the assumption that for a person to
be happy it is enough that they want what they can achieve and get. For
Aristotle this is not enough. In addition to it we need to study the
ultimate nature of the world. That Aristotle?s position is more likely to be
the case is indicated by contemporary research in psychology.

Published: October 2020

This study aimed to determine the strategies that are used in teaching reading to visually impaired students and the challenges in teaching reading to visually impaired students in SLB Negeri 1 Tabanan.  The research design used was a descriptive qualitative design. Subject of the study was the students with visually impaired in SLB Negeri 1 Tabanan which amounted 5 students. Data were collected by video recording, field note, and interview. Then, data were analyzed qualitatively. The results showed that (1) the English teacher used six strategies in teaching reading to visually impaired students in SLB Negeri 1 Tabanan, namely reading paper strategies (paper braille with pen reglet), reading e-text strategies (regular e-text with JAWS application), tracking support with JAWS application, auditory support (in the form of words and sentences level by using JAWS application), auditory strategies (live reader with a story entitled My School and live reader with multiple choice quizzes), and  digital audio (files with  a story entitled My School). (2) There were some challenges in teaching visually impaired students in SLB Negeri 1 Tabanan. One of them was the students were lack of vocabularies, so they could not response the lesson as good as normal students and the teacher needed longer time to teach those students. Second, the visually impaired students could not learn or did something individually, so they always needed assistance from the other people because visually impaired students could not see object around clearly. The last, the teacher looked a little difficult when showing an object to the students, because of the visual limitation experienced by students. It is suggested more strategies, software and application could be used to teach visually impaired students, and there will be more training or workshop for teachers so they have more experiences in dealing with students with special needs. Keywords: Strategies in Teaching Reading, Visually Impaired students
Microbiological Assessments in a Cut Flower Crop Polytunnel Field Trial Adopting Soil Covering and Microbiocides for Fusarium Wilt Suppression
Authors: Rao JR , Nelson David , Fleming Colin , Martin Trevor
Published: October 2020

Cut flower Matthiola incana were raised by local commercial cultivators in a polytunnel. The field soil beds were either left uncovered as normal or covered with polythene sheets (except a hole for plant plug space).  Average temperatures in the top 5 cm soil under cover dropped from 28 oC to 18 oC compared to its spiking up to 37 oC in uncovered counterparts. Microbiological analyses indicated that soil covering induced two log10 folds reduction of the wilt causal fungi Fusarium oxysporum and concomitantly increased one log10 fold wilt antagonistic natural soil inhabiting fungi populations. Standard dip/drench mixtures of commercial and local isolates microbiocides (bacteria) applied to M. incana plug roots improved plant health assessed by visible scores of the level of damage or wilt symptoms under soil covered treatments. Scanning electron microscopy, cultural and 16S rRNA PCR analyses revealed potent antifungal bacteria attached to the hyphal surfaces of F. oxysporum as ectosymbionts that may have implications for virulence regulation and host plants’ wilt disease control. Our microbiological data support the prospects of combining physiological and microbiological interventions upon covering the soil surface that offers the local horticulturists an evidence based sustainable means of Fusarium wilt control suppression in polytunnel crops.

Statistics on population change and the structure of population are increasingly used to support policymaking and to provide the opportunity to monitor demographic behaviour within political, economic, social and cultural contexts. Specifically, this concerns demographic developments that focus on a likely reduction in the relative importance of the working age population and a corresponding increase in the number of older persons. These statistics may be used to support a range of different analyses, including studies relating to population ageing and its effects on the sustainability of public finance and welfare, the evaluation of fertility as a background for family policies, or the economic and social impact of demographic change. This research aims to highlight the population change in twenty-five countries of the European Union. We consider the use of categorical data analysis to estimate the population change in EU25: absolute numbers and crude rates from 2003-2017. The data used in this study are from the Eurostat/World population prospects and estimated on actual base year from. Since the main focus is to have a better understanding of the population change in EU25, the analysis of association table (ANOAS) is given in order to ascertain the percentage of the data which is covered by each model. We find and estimate the association model with the best fit and in conclusion we find out that the Row-Column Effects Association Model (RC) of the multivariate model (M=4) has the best fit among all - covering a total of 99.9% of the data observed.

Analyzing the Impact of Human and Technological Factors on Warehouse Productivity
Authors: Wanjari Sushant Siddharth
Published: October 2020

Warehouse productivity depends on the efficiency and effectiveness of the operators and the equally capable and optimized Warehouse Management Systems (WMS) system. The warehouse operators come with a diverse skill set and experience to perform the job. Likewise, the WMS system could be simple or complex depending upon how it is customized. Also, there are technological infrastructure limitations that hinder the ability of the operator to perform the job. This research paper outlines the result of a survey conducted over 200 respondents to find the major human and technological factors and their impact on warehouse productivity. The questionnaire used a Likert scale where the respondents had to agree from one (1) to five (5) among fourteen (14) statements. Factor analysis is used to identify the correlation among those factors. The results show the most statistically significant correlations, and for future research an extended sample size can be targeted.

Growth Potential of Different Fungicide Resistant Alternaria solani Isolates of Tomato Leaf Blight Pathogen, under In Vitro, in the Presence of Different Fungicide, Growth Temperature and pH Ion Concentration
Authors: Chavan V. A. , Borkar S. G. , Kadam Nivedita A
Published: October 2020

Evolution of fungicide resistance in plant pathogens and cross resistance to other fungicides in such pathogens is one of major concerns in sustainable plant disease management. Frequent and unwarranted use of fungicides to control plant diseases not only pollute the earth soil and environment, but also causes the development of fungicide resistance in the plant pathogens, which makes it difficult to manage the plant disease. In India, particularly in western Maharashtra, Alternaria leaf blight pathogen of tomato developed resistance and cross resistance to various fungicides. How these fungicide resistant isolates grow in the different fungicidal environment is reported in the present investigation. Eight different fungicide resistant isolates of Alternaria solani responsible for causing leaf blight in tomato crop were tested for their growth potential, under in vitro condition, on the potato-dextrose-agar(PDA) growth media amended with different fungicides viz. Dithane M-45, Blitox, Kavach, Ridomil, Nativo, Bavistin, Captaf and Score. Different fungicide resistant isolates showed different pattern of growth i.e. complete inhibition of growth, reduced growth or enhancement of growth on different fungicide amended PDA media. The growth of Dithane M-45 resistant isolate was enhanced by fungicide Kavach and Bavistin while reduced by fungicide Blitox. The growth of this fungicide resistant isolate was completely inhibited by fungicide Ridomil, Nativo, Captaf and Score. The maximum enhancement of growth was for Nativo resistant isolate to Bavistin amended PDA media. Bavistin resistant isolate had decreased growth on all fungicides amended PDA media. The minimum reduction in growth was recorded for Kavach resistant isolate on Dithane M-45 fungicide amended PDA media. The growth rate (cm/day) of these fungicide resistant isolates was maximum at 220C temperature as compared to 25 and 300C temperature on the routine PDA growth medium. Captaf resistant isolate produced more growth followed by Nativo, Dithane M-45 and score resistant isolate. The minimum growth was observed for Blitox resistant isolate. As the temperature increases, the growth rate decreased. The growth of fungicide resistant isolates was favored by neutral pH of 7.0 and decreased toward the acidic and alkaline condition. Captaf resistant isolate produced more growth followed by Nativo and score resistant isolates. The minimum growth was produced by Blitox resistant isolate. More growth of fungicide resistant Alternaria isolate means production of more inoculum for disease initiation and spread which is favored at 22 °C temperature and further indicate which fungicide should be used to restrict/manage the growth of particular Alternaria fungicide resistant isolate.

Authors: Inyang U. E. , Elijah V. P.
Published: October 2020

The demand for food products with functional attributes is on the increase worldwide. The present study was aimed at evaluating the effect of supplementing whole wheat flour with 0, 10, 20, 30, 40 and 50% whole green plantain flour on pasting properties of the flour blends, proximate composition, minerals and sensory characteristics of crackers made from the blends. The 100% whole wheat flour served as the control sample. The result showed that the peak viscosity (PV), trough viscosity (TV), breakdown viscosity (BDV), final viscosity (FV) and setback viscosity (SBV) were significantly affected by the level of plantain flour substitution. The 20% plantain flour substitution level recorded the minimum PV (264.00RVU), TV (248.00RVU), FV (531.00RVU) and SBV (263.00RVU) while the 50% plantain flour substituted blend recorded the highest PV (362.00RVU), TV (328.00RVU) and FV (603.00RVU). The control sample recorded the highest SBV (312.00RVU) and least BDV (3.00RVU). The peak times for all the blended samples were the same (7 min) while the time for the control sample was 5 min. There was insignificant difference (P>0.05) in the pasting temperature which ranged from 91.30 – 92.80oC. The crude protein, fat and calcium contents progressively decreased while the ash, crude fibre, carbohydrate, K, Mg, Fe and Zn contents in the prepared crackers progressively increased with increase in the proportion of plantain flour substitution. Cracker prepared from the blend of 80% whole wheat and 20% whole green plantain flours was the most preferred by the sensory evaluation panellists in terms of taste, texture and overall acceptability. It is evident from the study that acceptable crackers of enhanced nutritive value could be produced from blend of 80% whole wheat and 20% whole green plantain flours. The use of flour from unpeeled plantain as ingredient in cracker production would eliminate waste generation and its associated environmental problems.

The estimated daily intake (DIM) of heavy metals from vegetables irrigated with tin mine pond water were in the order: Cd > Zn > Mn > Cr > Cu > Pb > As.  The health risk index (HRI) of all the studied heavy metals indicated that all vegetables were safe with no risk to human health except for Cd.  health risk assessment of heavy metals in consumption of vegetables irrigated with tin mine pond water in Jos - South, Plateau State
Effect of Slenderness Ratio on Fatigue Life of CFRP Strengthened Steel I-Beam
Authors: ISLAM Md. Shariful , HASİB Md. Abdul
Published: October 2020

Carbon fiber reinforced polymers (CFRP) to repair and strengthen the steel I-beam has been increasingly used since last decade. CFRP composites bonded to steel members offer many advantages over steel plate bonding including excellent corrosion resistance, high stiffness and high strength to weight ratios etc. This study numerically investigates the fatigue performance of CFRP strengthened steel I-beam. One non-strengthened control beam and several strengthened beams using steel plates and CFRP strips were investigated primarily. The effect of slenderness ratios of web on fatigue behavior of CFRP strengthened steel I-beam is investigated. The beams were simulated in full three-dimension and fatigue life was investigated by using general-purpose ﬁnite element program, ANSYS. Simply supported beam subjected to two loads on compression flange is analyzed to show the effect of CFRP and slenderness ratios on fatigue behavior of steel I beam. The results show, that the life cycle of a CFRP strengthened beam before failure is higher than that of bare beam. It is also observed that beams with higher slenderness ratios (fixed thickness of the web) give better fatigue performance.

POSTCOLONIAL THEORIES ON PROMOTING WORLD ENGLISH IN EFL SPEAKING CLASSES
Authors: Lukitasari Desy Rizki
Published: October 2020

English, as one colonial’s legacy, is a lingua franca. It connects people with different first languages and cultures around the world. As the demand of 21st century learning, the learning of English in EFL speaking classes has changed. It no longer focuses on how to speak like native speakers, but to speak like an educated person; to speak in English confidently and fluently, demonstrating good grammar and correct pronunciation. Therefore, World English with different accents and dialects exist. Furthermore, to explain the nature of English which is the result of Western dominaton during colonialism and imperialism, Postcolonial theories can explain the significance of World English in EFL speaking classes. This library research, then, aims to answer this research question: ‘How do postcolonial theories contribute significances to the use of the World English in EFL speaking classes?’. From the theoretical analysis employed from experts, important figures, and previous prominent theories and findings on discussing the same topic, there are two postcolonial theories which contribute to the existence of the World English in today’s EFL speaking classes. First,  English Linguistic Imperialism which influenced the Other, East, or Orient to feel it was compulsory to speak in English like natives in the past. Second, Bhabha’s hybridity and Fanon’s cultural resistance which help to give an understanding about accepting mixed cultures and identity. Finally, the discussion of the study will raise an awareness of how Postcolonial theories relate to the presence of the World English used by non-native English speakers and give an insight to EFL learners and practitioners about the World English in speaking classes.
