Published: July 2018

ABSTRACT Potato (Solanum tuberosum L.) is a nutritionally demanding crop, and phosphorus (P) is a nutrient that exerts a large effect on tuber yield. However, as the availability of P is influenced by soil texture, there are doubts about how P supplementation affects the growth and yield of potato plants in different soil textures. Thus, here we aimed to evaluate the effect of P fertilization and soil texture on the nutrition, growth, tuber yield, and P use efficiency (PUE) of potato plants. The experiment was conducted under greenhouse conditions in a randomized block design with a 4×2 factorial scheme and five replications. The treatments were represented by four P rates (10, 50, 100, and 200 mg dm-3 P) and two soil textures (clayey and sandy). The concentrations of P, Ca, and Mg in the leaves were higher in sandy soil, and P rates increased the concentrations of N, P, and Ca in the leaves of potato plants. Phosphorus fertilization increased plant growth, the amount of P accumulated in the shoot, and tuber yield in both soils; this trend was stronger in the potato cultivated in the clayey soil than in the sandy soil. The applied-PUE was not affected by soil texture. In the potato cultivated in the sandy soil, the taken up-PUE was reduced due to the decrease in dry matter production and an increase in P concentration in the organs of the plant with higher P fertilizer rates.
ESTIMATION OF PHYSICAL AND CHEMICAL SOIL PROPERTIES BY ARTIFICIAL NEURAL NETWORKS
Authors: BITTAR ROBERTO DIB , ALVES SUELI MARTINS DE FREITAS , MELO FRANCISCO RAMOS DE
Published: July 2018

ABSTRACT Soil physical and chemical analyses are relatively high-cost and time-consuming procedures. In the search for alternatives to predict these properties from a reduced number of soil samples, the use of Artificial Neural Networks (ANN) has been pointed out as a great computational technique to solve this problem by means of experience. This tool also has the ability to acquire knowledge and then apply it. This study aimed at using ANNs to estimate the physical and chemical properties of soil. The data came from the physical and chemical analysis of 120 sampling points, which were submitted to descriptive analysis, geostatistical analysis, and ANNs training and analysis. In the geostatistical analysis, the semivariogram model that best fitted the experimental variogram was verified for each soil property, and the ordinary kriging was used as an interpolation method. The ANNs were trained and selected based on their assertiveness in the mapping of considered standards, and then used to estimate all soil properties. The mean errors of ordinary kriging estimates were compared to those of ANNs and then compared to the original values using Student's t-Test. The results showed that the ANN had an assertiveness compatible with ordinary kriging. Therefore, such technique is a promising tool to estimate soil properties using a reduced number of soil samples.

Apresentam também os comentários de outros eticistas, contra ou a favor dos argumentos apresentados por Pellegrino, e comparam aspectos da referida moralidade externa à teoria do consenso moral desenvolvida anteriormente pelos autores.
Análisis de la ética de principios, 40 años después
Authors: Roqué-Sánchez María Victoria , Macpherson Ignacio
Published: July 2018

Resumen La Bioética de principios se ha convertido en un paradigma de la valoración moral en la práctica clínica. La estructuración en cuatro principios (autonomía, beneficencia, no maleficencia y justicia), elaborada por Beauchamp y Childress hace casi 40 años, trata de facilitar la toma de decisiones en un contexto universal. Aun así, este objetivo genera una serie de dudas que afectan profundamente a la praxis ética de la medicina y a la teoría moral. Por ello, se hace imprescindible un análisis crítico de los principios de la Bioética, su fundamentación teórica y su aplicabilidad, a la vista de los resultados en estos últimos decenios.

Published: July 2018

Resumo Objetivou-se identificar a atitude de profissionais e acadêmicos de enfermagem, fisioterapia, medicina e psicologia de um hospital universitário perante suicídio assistido e eutanásia. O estudo foi desenvolvido por meio de questionário de autopreenchimento e contou com 354 participantes, entre os quais, 68,1% concordaram com a legalização do suicídio assistido e 73,2% com a legalização da eutanásia para pacientes com doenças terminais. A concordância com a legalização do suicídio assistido ou da eutanásia foi de 46,9% em casos de pacientes com doenças neurodegenerativas progressivas e de 30,8% em casos de tetraplegia. Em casos de doenças terminais, se legalizados, 45% dos participantes cometeriam suicídio assistido, 57% solicitariam eutanásia, 36,5% auxiliariam suicídio assistido e 39,9% auxiliariam eutanásia. Conclui-se que a ampla aceitação da legalização da eutanásia e do suicídio assistido entre os participantes enfatiza a necessidade de se ampliar a discussão sobre o tema entre a população.
Suspensão de nutrição enteral a pacientes em coma persistente
Authors: Palhares Dario , Santos Íris Almeida dos , Cunha Antônio Carlos Rodrigues da
Published: July 2018

Resumo Estado vegetativo persistente é condição clínica definida como período prolongado, de seis meses a um ano, em estado de coma, sendo somente possível com tecnologia médica. Em alguns países, é lícito aos responsáveis legais solicitar a suspensão de nutrição enteral a esses pacientes, o que certamente leva a óbito em intervalo de poucos dias. É necessária terminologia para diferenciar limitação terapêutica, negligência e eutanásia. A limitação terapêutica surge no momento de intercorrências agudas em pacientes crônicos terminais, enquanto a eutanásia é pedido de morte controlada. Conclui-se, portanto, que a retirada intencional de suporte nutricional a esses pacientes é prática de eutanásia.
Bioética e direito humano à alimentação adequada na terapia nutricional enteral
Authors: Gonçalves Eloisa Cristina , Morimoto Ivone Mayumi Ikeda , Ribeiro Cilene da Silva Gomes , Cunha Thiago Rocha da , Corradi-Perini Carla
Published: July 2018

Resumo Este estudo objetiva refletir à luz da bioética a incorporação do conceito de direito à alimentação adequada no âmbito da terapia nutricional enteral. Trata-se de estudo longitudinal realizado com pacientes em nutrição enteral internados em hospital universitário brasileiro. O respeito a esse direito foi verificado a partir da análise de adequação da dieta oferecida aos pacientes. Os resultados demonstram que menos da metade dos pacientes recebeu dieta adequada (quantidade e qualidade), principalmente por fatores ligados a doenças e ao tratamento (diarreia, náuseas e vômitos, estase gástrica, jejum para exames/procedimentos). Entretanto, observa-se que limitação de recursos financeiros e fragilidades na organização dos serviços contribuem para essa realidade. A terapia nutricional enteral evoluiu nas últimas décadas em relação a regulamentações e disponibilidade de produtos, porém a análise bioética evidencia que há desafios a serem enfrentados para que o direito em questão seja garantido também no contexto clínico e terapêutico.
Problemas e conflitos bioéticos da prática em equipe da Estratégia Saúde da Família
Authors: Marin Juliana , Ribeiro Carlos Dimas Martins
Published: July 2018

Resumo O objetivo deste trabalho é analisar a gênese e expressão de problemas e conflitos éticos que emergem durante o trabalho de uma equipe da Estratégia Saúde da Família. Esta investigação qualitativa considera três etapas de operacionalização: etnografia, entrevista e grupo focal. O principal problema ético encontrado é o descompromisso de profissionais em relação a outros profissionais e paciente, o que, por consequência, desencadeia outros problemas éticos, como absenteísmo, procrastinação e fragmentação da equipe. A origem desses problemas está relacionada à ausência de razoável competência interpessoal, a necessidades profissionais não atendidas, à hierarquia e à pouca maturidade psicológica. Sendo assim, são necessárias estratégias de intervenção tanto na gênese quanto nos problemas e conflitos éticos para que o trabalho em equipe não se estabeleça em pseudoequipe em detrimento do cuidado.

Published: July 2018

ABSTRACT Objective To characterize the care flow and the primary diagnoses of an Adolescent Medicine Clinic. Methods A retrospective descriptive study, with analysis of clinical processes of adolescents (10-18 years) seen at the Adolescent Medicine Clinic, from January 2006 to December 2013. The following variables were analyzed: sex, age, number of visits, referring service and primary diagnoses according to the International Statistical Classification of Diseases and Related Health Problems. As to the variable age, the adolescents were divided into two groups: Group I comprised those aged 10-14 years, and Group II, 15-18 years. Results A total of 7,692 visits were carried out, in that, 1,659 first visits (22%), with an annual growth rate of 6%. The mean age was 14.2 years, and 55% of patients were female. The group of endocrine, nutritional and metabolic diseases was the most representative in our sample (34%), with obesity being the most frequent diagnosis in both sexes and age groups (23%), with a higher prevalence in males (13% male versus 10% female, p<0.001) and younger adolescents (18% in Group I versus 5% in Group II p<0.001). The group of mental and behavioral disorders was the second most prevalent (32%), affecting mainly females (39% female versus 22% male, p<0.001) and the older age group (39% Group II versus 27% Group I, p<0.001). Social problems were the primary diagnosis in 8% of visits. Conclusion Most diseases diagnosed have a strong behavioral and social component, particularly mental disorders and obesity. This specific type of diagnoses reinforces the need for a global approach for adolescents and specialized adolescent medicine units/clinics.

Androcentrism of English proverbs and Anti-Proverbs with Gender Components
Authors: Kirsanova Maria
Published: July 2018

Since the 20th century with the birth of feminism, gender studies have undergone analysis in many areas of knowledge. Special attention has been paid to the theory of androcentricity in the English language and the deficiency of female images in speech. In this article, the images of men and women presented by English proverbs and anti-proverbs are analyzed. The objective of this research is to find out if proverbs are androcentric and present male mindsets and world views. The other aim is to check whether anti-proverbs reflect the changing role of women in society. To fulfill these purposes, proverbs with gender components (man/woman, wife/husband, he/she etс.) were selected and underwent a semantic analysis. In order to reveal the evolution of the images of men and women we compared the images of men and women illustrated in proverbs with those shown in anti-proverbs with the same gender components. As a result, we came to the conclusion that both proverbs and anti-proverbs are androcentric; however, in anti-proverbs female opinions are more representative when compared to proverbs. To sum up, it is obvious that the role of women is changing and the changes are reflected in the language.
French Grammatical Accents: Practices, Sociolinguistic Foundations, and Pedagogical Implications in a Multilingual Setting
Authors: Ndzotom Mbakop Antoine Willy , Emalieu Kanko Sonia Laurei , Tida Adrienne Michelle
Published: July 2018

The present paper probes the use of French grammatical accents by English-speaking learners of French in a multilingual country: Cameroon. Its aim is twofold. First, it highlights the extent to which the various appropriative uses of French by French-speaking Cameroonians influence the form of the language spoken by their English-speaking counterparts. Then, it checks the effect of the language spoken by these learners on their written language. The data were collected among 160 Form 3 and Form 4 pupils from two high schools in the town of Maroua, Far North Region, Cameroon. Six tests and fifty tape recordings were carried out among the target population. Also, four French teachers were tape recorded during the exercise. The analysis of the errors made by the informants revealed significant patterns of acute and grave accents in the spoken language of respondents. These patterns of oral usage were found to strongly correlate with their written production. It therefore appears that Cameroon French displays some specific phonological characteristics, which severely spoils the acquisition of grammatical accents by English-speaking Cameroonians. These findings may revive the debate over whether French in former colonies should adapt to its contexts or keep its native purity.
Overcoming the Grammar Barrier in Foreign Language Learning: The Role of Television Series
Authors: Azaryad Shechter Deborah
Published: July 2018

Mastering the grammar of a foreign language requires learning the rules as well as the contexts within which the structures are used. Formal grammar instruction should therefore be augmented by exposing learners to authentic language. According to the literature, watching television series in the target language improves listening comprehension and enhances vocabulary acquisition. No study to date, however, has investigated the recursive use of one series, in the classroom and over an entire course, to explicitly teach grammar. Presenting apt pedagogical arguments substantiated by the literature on grammar instruction and evidence from the classroom, this article maintains that a television series can be an invaluable source of authentic language and an excellent means to teach grammar in context. It recommends using the dialogues in the scenes to teach and illustrate grammatical structures, especially those that are very different or do not exist in the learners’ mother tongue. The article also proposes giving students pertinent writing tasks and adequate corrective feedback to help them internalize these structures. Consistent with recent studies indicating a strong connection between emotion and cognition, this method raises the students’ motivation and enhances grammar learning; as such, it can supplant or complement conventional practices of grammar instruction and thereby warrants empirical studies. Finally, the article delineates directions for future research to elucidate how television series contribute to the teaching and learning of grammar.
The Origin of the Concept “Tianxia” in the Political Ideological Configuration of Traditional China
Authors: Yuchen Zhang
Published: July 2018

The concept "Tianxia" (All-under-Heaven) could be a parallel concept of the "Empire" in the West, which also allows a better understanding of the Chinese history with its own political language. This concept not only serves to legitimize the dominion of the Tianzi (Son of God Heaven) in China, but also makes possible a political internalization instead of the territorial expansion in the East Asian area. The "Heaven" (or Sky) is fundamental to understand the revolution of power in Ancient China, with the various meanings in which it has been interpreted. This is finally recognized as the supreme god, that the Tianzi inherited and obtained dominion over the corresponding earth. However, with the divine and ethical nature of Heaven, the dominator is required to have the virtue and good execution of power to keep the authorization in hand. With this text, the origin and the main development of the Tianxia system are revealed as the legitimizing regime of Chinese politics.

Published: July 2018

este trabajo escrito presenta un análisis al panorama que generaría la implementación de una base de datos de adn sistematizada, unificada y centralizada al servicio de las investigaciones y procesos que se adelante dentro de sistema penal acusatorio colombiano. para ello, se consolidan tres propósitos a saber: primero el referente a los métodos y técnicas científicas que permiten la identificación de personas mediante la extracción y examen de adn que facilitaría la elaboración de una base de datos de adn al servicio de la jurisdicción penal. el segundo es identificar los escenarios de confrontación de los derechos fundamentales de los ciudadanos colombianos con la implantación de una base de datos estatal que permita la recolección del adn de todos los habitantes del territorio, y el tercer propósito lo constituye determinar las expectativas en costo y beneficio en la implementación de la base de datos de adn para la administración de justicia colombiana, en especial para el sistema penal acusatorio. la información fue recolectada mediante metodología de análisis y síntesis, obteniendo como resultado que la implementación de una base pública de datos de adn puede ser una de las respuestas al problema de la congestión judicial en los procesos penales, donde es indispensable el uso de la técnica de adn y por ende significaría un menor grado de impunidad y mayor eficacia de la justicia penal.
El poder nacional y su inconveniencia política
Authors: VÁSQUEZ HINCAPIÉ DANIEL JOSÉ
Published: July 2018

la constitución política de colombia contempla en su texto solo dos poderes en el estado, el primero, el poder soberano del pueblo, el otro, derivado del primero, el poder público, reconocido en sus tres ramas: legislativa, ejecutiva y judicial, donde el ejecutivo recoge la organización administrativa del estado con una característica de funcionalidad, así; por ejemplo, la defensa del país le corresponde al ministerio de defensa mediante el accionar de sus fuerzas militares.

en la organización estatal, como aquella que rigió hasta 1991, la soberanía era ejercida por el estado, sujeto activo de las normas y, por ende, su beneficiario.

en contraste, en el presente estado social de derecho se erigió a las personas como sujetos activos y beneficiarios, mientras que el estado se constituyó en un sujeto obligado o pasivo. para el caso de la defensa nacional, esta pasó a ser responsabilidad del estado para con sus ciudadanos, criterio de notable significación en la transformación de las nociones de poder en todas sus formas, puesto que, en relación con la defensa, el poder nacional ya no es la suma de todas las capacidades de los ciudadanos, sino solamente la de aquellos que libremente se comprometan en su realización. igual relación ocurre con el llamado poder económico, político o sicosocial de la nación, ya que no hace parte total del poder nación, por factores como la globalización que afectan al poder desde el exterior, al igual que lo hace el pluralismo en el interior.

cualquiera que sea la posición asumida por el ciudadano, corresponde al estado determinar los elementos con los cuales dé respuesta a las necesidades y, en el caso de la defensa nacional, deberá aceptar que el poder difiere del potencial, que todo no está disponible y que sus políticas hacia las fuerzas militares deben ajustarse a estas nuevas realidades, para que los planes militares estén de acuerdo con la medida de la capacidad política y administrativa del estado.

Three-phase Active Power Filter Based on The Four States Commutation Cell DC-AC Converter. Design And Implementation
Authors: Cortez Daniel Flores , Boris Luis Corral Martinez  , Barbi Ivo
Published: July 2018

This work approaches the subject of Active Power Filtering for the cases where the current stress of the semiconductor devices is a point of major concern. Instead of the classic parallelism of inverters, a topology with coupled inductors is proposed to address this problem. In addition, this topology provides advantages from the point of view of the output current ripple, providing more flexibility on the design of the filter inductors. A more simple and cost-effective control strategy based on the sensing of the AC source currents is implemented using the Park transformation. Simulation and practical experiments are presented in order to prove the correct behavior of the system. The experimental set-up consists on a nonlinear load rated for 8 kVA connected to a 380 V (line-to-line) AC grid, trough an isolation transformer. A Four States Commutation Cell, DC-AC Converter is connected as a shunt Active Power Filter with a DC link voltage of 600 V. The control algorithm is programmed on a DSP board TMS320F28335 from Texas Instruments.

Authors: Moutaoukil Fouad , M’barki Mohamed Amine , Boungab Souad
Published: July 2018

Based on the current economic environment of companies, with the focus on core business and the increasing use of outsourcing, a good relationship management with suppliers is very crucial to increase the performance of the companies. Since the rate of purchases in the value added of the product keeps increasing, suppliers who are considered as partners have a significant role to play. This situation poses the problem of managing the customer-supplier relationship because a greater part of the performance depends on suppliers and the service providers. Due to these observations, there is the need for companies to secure their supply chain, especially in terms of QCD (Quality, Cost and Delay). The control of these three elements is a solid asset that is used to remain competitive and to keep their strategic stake in the logistics chain. The SCM practices related to supplier management are defined as a set of activities within an organization to ensure an effective supply chain management. This paper focuses on exploring the best practices in term of supplier management used to ensure high performance in the automotive sector in Morocco. In other words, the objective of this research is to assess the actual state and the perspectives for applying a security approach and an appraisal of the suppliers’ performance, based on management practices and a combination of quality and logistics audits. This research contributes to the study of the link between the SCM practices and the performance based on a qualitative approach applied with a business case within the automobile manufacturer Renault Tanger in Morocco.

Published: July 2018

This research paper discusses the influence of new five year automobile policy announced by Economic Coordination Committee (ECC) in March 2016 for the period from 2016 to 2021 comparing with the old auto policy announced by the Government of Pakistan. The crucial point of this paper is to find the critical aspects of new auto policy and their impact on the profitability of major players in automobile industry of Pakistan. Main objectives of this policy are to help increase the volume with improved quality, catch the attention of investors, creating an extensive competitive environment, minimizing costs, technological improvement, satisfy all stakeholders through a Balance between tariffs and growth, customer satisfaction and Eliminating Monopoly of Existing Car Manufacturers. The important rationale of this paper is to have a look on the prevailing situation of automobile industry and the potential of this industry after the implementation of new auto-policy for 2016-21. It is to analyse whether this policy may influence profitability of the firms those have created their monopoly in this sector of Pakistan. The results of the study reveal that the profitability of major players of the automobile industry those were creating monopolies is not expected to decline even after the new policy. It may because of the trust of people on the local makes or expected ease in maintenance than those of the imported ones. However, the circumstances may change based on the customers’ behavior that may cause the shift of their profit share to the New Entrants. Nevertheless, exploring the industrial alliance in this sector globally is of high importance for better quality, reasonable costs, fuel efficiency and striking designs. Various studies have been conducted to highlight the impacts of different policies announced by the governments for automobile industry worldwide and for the Pakistan as well. Consequently, this study will be useful to seek out the probable challenges to confront in the automobile industry and to provide support for the future policies related to automobile companies and interrelated businesses like leasing, insurance, tracking and auto finance.

Our objective in this article is to understand the characteristics of the entrepreneurship of the population of Lebanese origin in Côte d’Ivoire from the perspective of the ethnic network. In other words, it is about appreciating impacts of the Lebanese ethnic network on the development of their entrepreneurial activities, by scrutinizing the modalities such as the support for the immigration, the departure in business, the discovery of the entrepreneurial opportunity, the financing of the entrepreneurship and even the motive in the entrepreneurial commitment. To this end, this article joined within the framework of the studies relative to the ethnic and/or immigrant entrepreneurship. This research thus left the Anglo-Saxon literature on the ethnic entrepreneurship and a field survey to seize how the ethnic network constitutes a major element of the economic integration of the Lebanese by the entrepreneurship in Côte d’Ivoire. In fact, their ethnic network of the Lebanese boosts their entrepreneurship through a shape of selection in the immigration; the family unit - by the tourism or the visit of the family - organizing the arrival of the new migrant until the obtaining of its first employment pending the acquisition of the Ivorian experience or the capital of the future business and the discovery of the entrepreneurial opportunity.

Published: July 2018

Student’s relationship with teachers is important because students spend about 7 to 9 hours a day and almost 11 months with the teacher. This paper focuses on ascertaining the impact of communication between teachers and students. Communication is a motivational tool for students to accomplish their studies. In this era, education is spreading very quickly all around the world. Universities are trying to improve their standard by increasing the quality of education as well as the quality of their students. This study examines the challenges which create barriers and huddles due to communication between the teachers and students to ensure that the students succeed. For this purpose, the faculty of management science, University of Karachi, Pakistan, was used as a case study. Its impact on students through the teacher’s communication was examined. Three (3) departments are working under the faculty of management science. The random sampling method was used to gather the data from the departments. Descriptive analysis of mean and percentage were applied to find the impact of teacher’s communication on the student’s education and their success. The results show a positive relation between them. It is very difficult to create a positive relation between teachers and students when they get to a certain stage. This is because they are both mature, although it is necessary for both students and teachers. The qualities for a positive relationship can vary to make learning experience approachable and inviting for the students. If the teacher and the students have good communication skills and understand the importance of the impact of their communication, establishing a good relationship will be much easier. This research paper, however, shows that there is a positive relation between teachers and students which creates goodwill for the teachers and makes the students to be result-oriented.
Can We Talk About Transparency in Moroccan Public Finances?
Authors: Taouab Omar , Ameur Sara
Published: July 2018

The link between good governance and better economic and social outcomes is increasingly acknowledged. Transparency – openness about policy objectives, preparation and application – is a key element of good governance. Availability of reliable, relevant and timely information about the public finances allows the government and the citizens to see clearer. Upgraded public service delivery, including the providing of education, healthcare and sanitation, depends on the transparent and efficient management of public funds. Many nations still face challenges in the effective management of their financial resources. Therefore, Transparency is considered as an income to strengthening governance. For more than a decade, civil society organizations around the world, as well as international financial institutions, have been pushing governments to provide the public with more comprehensive budget information. The movement for greater public finance transparency has been gaining momentum in recent years; the recent global financial crisis has put even more emphasis on the importance of budget transparency. Calls for transparency, accountability, and equality have emerged in the whole world, especially the Arab world, with citizens summoning their governments to reveal their incomes and expenditures, as well as strategies and ambitions. To contribute to these efforts, we will be studying and analyzing the reference tools proposed by the international organizations for measuring the degree of budget transparency, and we will attempt to examine the finance transparency in Morocco.
Spatial Patterns of Agriculture in Boyacá
Authors: Arias Helmuth Yesid , Antosová Gabriela
Published: July 2018

This article figures out spatial patterns for Boyacá’s agriculture and exposes the behavior of production. Applying gravitational concepts we describe relevant spatial interactions across municipalities usingvariables as population, output and linear distances. We perform an econometric model for detecting the class of spatial dependence showed by agricultural output as endogenous using as arguments distance toTunja and rural population. We deploy standard tools of spatial analysis and empirical strategies for identify clusters of towns according with their performance and productivity. Statistical contrast indicates that the most suitable scheme for describing spatial dependence in production is spatial lag model. Econometrics conveys important clues demonstrating that higher scales output is conducted to urban national markets and output produced with scarce scales is sold locally in local towns. A strong subjacent idea is that lagged municipalities are badly influenced by geographical isolation and high transportation costs do hinder the social and economic development in Boyacá.
Los efectos socioeconómicos de las regalías petroleras en el departamento de Casanare, periodo 2004 – 2015
Authors: Pava Vargas Andrés Fernando , Lemos Valencia Alberto
Published: July 2018

Pese a que su destacable explotación de petróleo le ha permitido recibir significativos ingresos a título de regalías, la estructura socioeconómica alcanzada en el departamento de Casanare no ha sido la esperada. Por ello, la finalidad de este documento consiste en demostrar que la gestión y administración aplicada sobre estos recursos (representada por el índice de calidad institucional) no fue consecuente con los efectos socioeconómicos alcanzados en el departamento revisado, durante el periodo 2004-2015. Esta demostración, que dio lugar, al mismo tiempo, a una relación con la denominada maldición de recursos naturales para dicha región, se definió una vez analizados los resultados obtenidos con las regresiones lineales estimadas a través del método de mínimos cuadrados ordinarios, y sus comparaciones, con los resultados de los otros departamentos sobresalientes en producción petrolera, bajo los criterios del método de semejanza y diferencia de Ragin.
La comprensión lectora y el rendimiento escolar

Published: July 2018

Este escrito pretende determinar las posibles relaciones entre el nivel de comprensión lectora de los estudiantes y su desempeño académico. Se realiza un estudio descriptivo y un análisis estadístico correlacional. Se aplicó el instrumento Prueba de Competencia Lectora para Educación Secundaria (CompLEC) a estudiantes de ambos sexos con edades comprendidas entre los 13 y 14 años del grado noveno de educación básica de una institución educativa pública. A partir del análisis descriptivo, los estudiantes presentan dificultades en el orden textual, inferencial y contextual; en el análisis correlacional de los datos de las diferentes asignaturas (Ciencias Naturales, Ciencias Sociales, Lengua Castellana y Matemáticas) tienen una correlación significativa positiva, pero no significa necesariamente la existencia de una relación de causa-efecto.
El rol de la reflexión en la práctica pedagógica: percepciones de docentes de idiomas en formación

El presente estudio de caso tuvo como propósito conocer las percepciones de los estudiantes de un programa de enseñanza de inglés frente al rol de la reflexión en sus prácticas educativas e indagar sobre la estructura de la reflexión, incluyendo los aspectos que los practicantes más comúnmente comprenden a la hora de reflexionar. Para este propósito, fueron seleccionados nueve estudiantes practicantes, a los que se les analizaron ensayos reflexivos, reflexiones realizadas después de clase y la participación en un cuestionario virtual. Los resultados demostraron que los estudiantes practicantes percibieron la reflexión como un elemento fundamental e indispensable para encontrar soluciones frente a aspectos negativos de sus clases. Si bien los practicantes señalaron como una de sus motivaciones para reflexionar el hecho de ser un ejercicio obligatorio en la asignatura, también reconocieron la importancia de la misma como un elemento fundamental para su desarrollo profesional docente. El esquema más común seguido por los estudiantes en sus reflexiones fue la descripción de eventos de clase como paso previo a la reflexión. Como conclusión, se pudo establecer que los estudiantes aún se encuentran en un nivel básico de reflexión, lo que impulsó al programa de práctica a trabajar más sobre este componente.
Night air conditioning of buildings by external air ventilation
Authors: Bravo-Hidalgo Debrayan
Published: July 2018

Buildings contain the environment in which almost all human activities take place, and therefore, nowadays, they represent a great sink of energy. Establishing thermal comfort conditions within these buildings is responsible for a large portion of their energy demand. This paper aims at providing a theoretical framework of the performance and the trends in research and implementation of night air conditioning by outside air ventilation. The bibliographic search was conducted in the academic directory Scopus, and the information extracted was processed in the VOSviewer software, through which text mining, map of terms and networks of investigative action were carried out. The literature showed that direct ventilation has a more significant cooling potential in regions characterized by a high difference between day and night air temperatures. The effectiveness of night cooling and the reliable prediction of thermal behavior are strongly related to the model adopted for the convection algorithm. A reliable prediction of heat transfer by convection requires an approach based on computational simulations of fluid dynamics, which are much more demanding in terms of computational power, compared to simulations of the variation of energy flows as a function of time. Most studies showed that the position of the thermal mass is not significant, while the amount of ventilation air is of great importance. In particular, the energy demand for cooling a building decreases sharply if the air flow rates increase.
Didáctica de la literatura: técnicas didácticas de la estrategia del modelado estético
Authors: Altamirano Flores Federico
Published: July 2018

En el marco de la teoría del contagio literario, el presente artículo tiene el objetivo de proponer las técnicas didácticas para la concreción de la estrategia didáctica del modelado estético. A partir de la observación de las clases de literatura de los escritores Jorge Luis Borges, Vladimir Nabokov y Julio Cortázar y de la reflexión sobre los testimonios, opiniones y entrevistas de Daniel Pennac y Luis Landero, proponemos tres técnicas didácticas que podrían servir para despertar la pasión por la literatura en los estudiantes. Esas técnicas son la lectura expresiva, la lectura comentada y la narración oral y son concebidas como actividades discursivas que trasmiten la emoción y la experiencia literaria del profesor en el aula.
