Doubly–Negating Complicatedness of Undoing Love: A Stylistic Reading of I Can’t Unlove You by Kenny Rogers
Authors: Akun Akun
Published: April 2019

This wasa research about the role of linguistic features in contributing to the overall meaning of a song entitled I Can’t Unlove You by Kenny Rogers. The goal of the research was to prove that special linguistic features used in the song played a significant role in conveying the meaning of the song. This wasa library research by identifying and elaborating the special linguistic construction found in the song lyric text. It is concluded that the use of double negation combined with invented negative verbs has successfully build up the idea of impossibility in undoing love. This double negative expression is needed because love intricacy and complicatedness can only be expressed in a stylistically special way where common expressions are unable to reach the intended meaning.
Komunikasi Politik Pemerintah Susilo Bambang Yudhoyono (Sby) (Studi Kasus Masalah Bahan Bakar Minyak Tahun 2012)
Authors: Tukina Tukina
Published: April 2019

Price of international oil and gas has fluctuatively increased from time to time. The reality encourages the government of Susilo Bambang Yudhoyono (SBY) to raise (or adjust) the price of fuel in the country. Viewed from the history, since the era of President Soekarno, Soeharto, Megawati, and Gusdur fuel price increase policy has always been controversial, inviting pros and cons, although the actual adjustment is reasonable and necessary. Government policy of SBY to raise fuel prices and ultimately failed is interesting to learn. This study focused on the political communication of SBY government. The SBY government's efforts to raise fuel prices got tough challenge from several people, including members of the Parliament. The pros and cons protracted and eventually the SBY government failed to raise the fuel prices. Methodology of this article used descriptive-qualitative research. Data obtained through field observations and literature. Data were analyzed descriptively based on research purposes. Role of the writer in a descriptive qualitative study was the main thing. Results showed that the failure of SBY political communication was caused by the failure in convincing Indonesian people. SBY government needed to clarify and reinforce the authority to raise fuel prices belong to the Government. Any information (messages) should be communicated directly, clearly, and firmly through the process. Messages from the source to the target (society) needs to be maintained properly. If not, the messages can be misused. Each message can be added, subtracted (either partially or completely) which will lead to misunderstanding, biased, confusing, and protracting situasions.

Authors: Kurnianto Arik
Published: April 2019

This study has primary focus to analyze the aesthetic layout of a newspaper with a mathematical approach, which refers to some methods of Birkhoff’s aesthetic measurement developed by David Ngo Chek Ling, et.al. Ngo developed a method of measuring the aesthetic layout that can be used for various design purposes, especially for a computer interface design. Measurement method that he developed refers to the principles of design aesthetics, such as: the principle of balance, the principle of sequence, the principle of unity, and the principle of equilibrium. Birkhoff aesthetic measurement method was used as final analysis to determine the value of aesthetic layout. In this study, some national and local media were selected as samples to determine and assess the aesthetic layout. Based on data analysis, Birkhoff aesthetic measurement method can be applied to measure the aesthetic value of the newspaper layout mathematically.
Penelitian Atas Penelitian Seni dan Desain: Suatu Studi Kerangka Filosofis-Paradigmatis Bagi Penelitian Seni dan Desain Visual
Authors: Mustaqim Karna , Adiwijaya D. Rio , Indrajaya Ferdinand
Published: April 2019

This paper discusses philosophical framework of practice-based artistic research within the field of art and design in contrast with research in the natural and social science. It is stated that paradigm of artistic inquiry is ilustrated with the role of practicioner as researcher wherein subjectivity, involvement and reflexivity are acknowledged, while (k)nowledge is negotiated – inter-subjective, context bound, and is a result of personal construction. Visual objects have been exhausting large amount of our physical and emotional energy in seeing it which certainly gives them a central role in contemporary ages. It is suggested that research could become part of the needs for experience, to inspire, or to collectively develop a profession. Recently, research as knowledge production has been increasing and gaining its interest within the creative art field. However, there is a foundation which underpins a research, at least some implicit philosophical assumptions of it, which serve as the basis of understanding of reality (ontology), and how to know and justify it (epistemology); and by explicating it, it is believed that scrupulous consideration of it may contribute practical benefits in conducting art and design research. In that regard, this paper presents ontological outlook of Heidegger and also epistemology of art of Merleau-Ponty – which rises within phenomenological tradition – as a philosophical framework which can serve as paradigmatic underpinning of artistic research, in contrast with objectivist approach already identical with research in general.

The biggest difficulty of humans cannot change or advance the quality of life is an unwillingness to change their errors and shortcomings and to repent from it. There is also willing to change but they do not change just because no action and do not really do it. There are also people who have already known that it is true, accurate, should be performed and corresponding to the norms, but still they live in sin and self-interest to ignore the interests of others. Even worse is evil (sin) is often covered in hypocrisy behind beautiful, sweet, gentle, and courteous words to make people mesmerized/hypnotized. In the case of real repentance, it should demand a match between words and actions. If there is repentance, there is a change and peace. Therefore, humans must sincerely repent and strive for it.

Published: April 2019

Ao considerar a globalização uma aliada à expansão das estratégias das organizações na internacionalização de seus negócios, a expatriação de empregados surge como um recurso de gestão de pessoas e, assim, oportuniza benefícios para as empresas e para o crescimento profissional e pessoal dos indivíduos. Portanto, este artigo teve como objetivo analisar a contribuição da expatriação para os processos de aprendizagem organizacional. Desenvolveu-se, para tanto, um estudo de casos múltiplos, com a participação cinco de empresas exportadoras do Rio Grande do Sul. A coleta de dados deu-se através de entrevistas com empregados que já foram expatriados ou que ainda se encontram em processo de expatriação, observações e pesquisa documental. Como resultados, pode-se observar que a expatriação tende a desencadear processos de aprendizagem organizacional que se encontram embutidos nas atividades cotidianas do indivíduo. Identificou-se que os empregados aprenderam, a partir de suas experiências, a enfrentar um problema ou desafio, através da reflexão, interação e colaboração com colegas. Além disso, a partir da expatriação, o expatriado enxerga a sua própria cultura sob uma nova ótica, toma conhecimento de outras culturas organizacionais e identifica novas formas de lidar com pessoas.

Authors: BARRETO Caroline Farias , FARIAS Roseli Mello , MARTINS Carlos Roberto , MALGARIN Marcelo Barbosa , MELLO-FARIAS Paulo Celso
Published: April 2019

O raleio manual de pessegueiros é uma prática necessária, mas onerosa e dificultosa para a produção de frutas. O uso de produtos com ação raleante é uma alternativa ao raleio manual, porém carece de informações sobre seu efeito na qualidade dos frutos. O objetivo do trabalho foi avaliar a qualidade dos frutos de pessegueiros após o raleio químico com o uso de diferentes doses de metamitron. O experimento foi conduzido em pomar comercial no município de Morro Redondo, Rio Grande do Sul, Brasil, durante as safras 2015 e 2016, na cultivar Maciel. Os tratamentos constituíram em plantas de pessegueiro sem raleio e o raleio químico com metamitron nas concentrações de 100, 200, 300 e 400 mg L-1. Foram avaliados a coloração da epiderme, firmeza da polpa, índice de maturação, sólidos solúveis, acidez titulável, compostos fenólicos totais e atividade antioxidante nos frutos de pessegueiros. A acidez titulável dos pêssegos aumenta com o incremento das doses de metamitron utilizado no raleio dos pessegueiros. O uso no metamitron no raleio reduz o teor de fenóis totais e atividade antioxidante dos pêssegos. Portanto, somente a acidez titulável e os compostos bioativos dos pêssegos são alterados pelo uso de distintas doses de metamitron no raleio de pessegueiro.
Święty Władysław w Pułtusku
Authors: Lolo Radosław
Published: April 2019

The article deals with the fate of the relics of Saint Władysław donated in 1585 by the Polish queen Anna Jagiellonka to the Jesuit college in Pułtusk. They were handed over from the royal treasury as evidence of gratitude for the education of Andrzej Batory - nephew of King Stephen I. Later the members of the Waza dynasty: princess Anna Katarzyna (1634) and king Władysław IV Waza (1635), fond homage to these relics. At that time he also gave them a silver reliquary as a gift. After the suppression of the Jesuits, the fate of the relics was unknown. Artifacts connected associated with them were found in the church of Saint Peter and Paul in Pułtusk in 2016. Research was unable to confirm that 7 of the oldest parts of a skull came from Saint Władysław`s skull which is now kept in Györ (lack of the DNA in the parts from Pułusk). Later, it was confirmed that these artifacts venerated in Pułtusk were relics of Saint Władysław. On the basis of the source analysis and comparison of the size of herms and pillows the author fixed that this herm, which was kept in Diocesan Museum in Płock, known as herm Saint Maurycy`s herm is in fact the herm donated to the Pułtusk`s Jesuits by Władysław IV in 1635 on Saint Władysław`s relics.
Marszałek Wielki Koronny Stanisław Herakliusz Lubomirski wobec Sejmu 1683 roku i problemu wojny z portą osmańską
Authors: Hundert Zbigniew
Published: April 2019

In 1683 Stanisław Herakliusz Lubomirski was one of the most important politicians in Polish-Lithuanian Commonwealth. He was part of anti-royal opposition, which was against alliance with Austria and war against Ottoman Empire. Lubomirski’s letters date before Warsaw Sejm indicates that he supported war against Muscovy. During Sejm he fulfilled his role as Grand Marshal, but at the same time he worked towards French interests. When the king and his supporters managed to defeat political opposition, Lubomirski switched sides and claimed that he never supported the king’s opponents. He then participated in signing a treaty with Austria and also enlisted few military units to take part in war against the Turks. After 1683, Sejm - for the time being - limited his political activities. Despite political defeat, he managed to achieve some personal successes – became owner of the town of Jazdów (Ujazdów), while his brother Hieronim was nominated for the office of Crown Court Marshal.

Authors: Kawczak Piotr , Bober Leszek , Bączek Tomasz
Published: April 2019

Background:

A set of β-lactam antibiotics, aminoglycoside antibiotics, and tetracycline
antibiotics were proposed and analyzed with the use of Quantitative Structure-Activity
Relationships (QSAR) method.

Objective:

The characterization of selected antimicrobial compounds in terms of both
physicochemical and pharmacological on the basis of calculations of quantum mechanics and
possessed biological activity data.

Methods:

During the study, Multiple Linear Regression (MLR) supported with Factor Analysis
(FA) and Principal Component Analysis (PCA) was made, as the types of proposed chemometric
approach; the semi-empirical level of in silico molecular modeling was used for calculations and
comparison of molecular descriptors both in a vacuum and in the aquatic environment.

Results:

The relationships between structure and microbiological activity enabled the
characterization and description of the analyzed molecules using statistically significant descriptors
belonging in most cases to different structural, geometric and electronic elements defining at the
same time the properties of the studied three different classes of examined antibiotics.

Conclusion:

The chemometric methods used revealed the influence of some of the elements of
structures examined molecules belonging to main antibiotics classes and responsible for the
antimicrobial activity.
Genome-wide Differential-based Analysis of the Relationship between DNA Methylation and Gene Expression in Cancer
Authors: Zhang Yuanyuan , Kou Chuanhua , Wang Shudong , Zhang Yulin
Published: April 2019

Background::

DNA methylation is an epigenetic modification that plays an important
role in regulating gene expression. There is evidence that the hypermethylation of promoter regions
always causes gene silencing. However, how the methylation patterns of other regions in the
genome, such as gene body and 3’UTR, affect gene expression is unknown.

Objective::

The study aimed to fully explore the relationship between DNA methylation and expression
throughout the genome-wide analysis which is important in understanding the function of
DNA methylation essentially.

Method::

In this paper, we develop a heuristic framework to analyze the relationship between the
methylated change in different regions and that of the corresponding gene expression based on differential
analysis.

Results::

To understande the methylated function of different genomic regions, a gene is divided
into seven functional regions. By applying the method in five cancer datasets from the Synapse database,
it was found that methylated regions with a significant difference between cases and controls
were almost uniformly distributed in the seven regions of the genome. Also, the effect of
DNA methylation in different regions on gene expression was different. For example, there was a
higher percentage of positive relationships in 1stExon, gene body and 3’UTR than in TSS1500 and
TSS200. The functional analysis of genes with a significant positive and negative correlation between
DNA methylation and gene expression demonstrated the epigenetic mechanism of cancerassociated
genes.

Conclusion::

Differential based analysis helps us to recognize the change in DNA methylation and
how this change affects the change in gene expression. It provides a basis for further integrating
gene expression and DNA methylation data to identify disease-associated biomarkers.

Authors: Obradović Ana , Matić Miloš , Ognjanović Branka , Vuković Nenad , Vukić Milena , Đurđević Predrag , Ušćumlić Gordana , Božić Bojan , Nedeljković Biljana B.
Published: April 2019

Background:

Hydantoin and its newly synthesized derivatives have recently become a focus of interest
due to their numerous biological activities and newly emerging beneficial effects in different pathological
conditions, including cancer.

Objective:

The aim of this study was to evaluate the possible anti-tumor mechanisms of a series of newly synthesized
3-(4-substituted benzyl)-5-isopropyl-5-phenylhydantoin derivatives in different aspects of cell physiology
of human colon cancer cell line, HCT-116.

Methods:

The increasing concentrations of derivatives (0.01µM up to 100µM) were applied to cells during 24h,
48h, and 72h after which the evaluation of proliferation, apoptosis, oxidative/anti-oxidative status, nitrite production,
and migration/invasion potential of treated cells was performed.

Results:

All tested compounds expressed the dose- and time-dependent anti-proliferative and pro-apoptotic
activities against HCT-116 cells. The investigated derivatives induced a decrease in levels of oxidative stress
parameters and an increase in levels of nitrite production by treated cells suggesting their significant antioxidative
effects. The cell migration index and expression level of tumor invasion-promoting metalloproteinase-
9 (MMP-9) gene were significantly decreased after treatment with the tested hydantoin derivatives implicating
their inhibitory role in colon cancer cell motility and invasion processes. The mRNA level of cyclooxygenase-2
(COX-2) gene as a pro-inflammatory gene related to colorectal carcinogenesis was reduced compared to values
in the non-treated control cells indicating the significant anti-inflammatory/anti-tumor effects of these compounds.

Conclusion:

The obtained results show the significant anti-tumor potential of tested derivatives, especially 3-
benzyl-5-isopropyl-5-phenylhydantoin and 3-(4-chlorobenzyl)-5-isopropyl-5-phenylhydantoin, suggesting their
potential usage in the development of more effective chemotherapies.
Vermamoeba vermiformis - A Free-Living Amoeba with Public Health and Environmental Health Significance
Authors: Scheid Patrick L.
Published: April 2019

Many case reports emphasize the fact that Free-Living Amoebae (FLA) can relatively easily get in contact with humans or animals. The presence of several facultative parasitic FLA in habitats related to human activities supports their public health relevance. While some strains of Acanthamoeba, Naegleria fowleri, Balamuthia mandrillaris and several other FLA have been described as facultative human pathogens, it remains controversial whether Vermamoeba vermiformis strains may have a pathogenic potential, or whether this FLA is just an incidental contaminant in a range of human cases. However, several cases support its role as a human parasite, either as the only etiological agent, or in combination with other pathogens. Additionally, a wide range of FLA is known as vectors of microorganisms (endocytobionts), hereby emphasizing their environmental significance. Among those FLA serving as hosts for and vectors of (pathogenic) endocytobionts, there are also descriptions of V. vermiformis as a vehicle and a reservoir of those endocytobionts. The involvement in animal and human health, the role as vector of pathogenic microorganisms and the pathogenicity in cell cultures, led to the assumption that V. vermiformis should be considered relevant in terms of public health and environmental health.
Reflective Inquiry on Professionals’ Views on Parents and About Parenting
Authors: Lam Ching Man
Published: April 2019

Although there are studies on attitudes and beliefs of parents in childrearing, there is a notable lack of studies
on professionals’ attitudes and beliefs about parents and about parenting. This study examines both professionals’ views
of parents and their attitudes and beliefs about parenting, and compares these attitudes and beliefs among different types
of professionals. The results indicate that professionals involved in parent education hold a moderately negative view of
parents despite being quite sympathetic to the stress experienced by parents. Findings also reveal an undue concern with
parenting knowledge and skills. Differences between teachers and social workers were found in perceived stress of
parents and perceived role of government. These findings provide an impetus to professionals, and to society at large, to
reflect on the values and attitudes they have towards parents and the family.
Antioxidant Activities, Binding Parameters, and Electrochemical Behavior of Superoxide Anion Radicals Twords 1-Ferrocenylmethylthymine and 1-Ferrocenylmethylcytosine
Authors: Lanez Elhafnaoui , Bechki Lazhar , Lanez Touhami
Published: April 2019

Background:

An electrochemical method based on cyclic voltametry techniques
was used to measure the antioxidant activity of two ferrocene-nucleobases.

Objective:

The present study aims to measure the antioxidant activity of two ferrocene derivatives
bearing nucleobases; the technique is based on the reaction of the in-situ electrochemical
generated superoxide anion radical with ferrocene-nucleobases.

Methods:

The decrease in the anodic peak current density of the O2 / O2
.− redox couple following
the addition of ferrocene-nucleobases was used to measure the antioxidant activity
and binding parameters of 1-ferrocenylmethylthymine and 1-ferrocenylmethylcytosine
with superoxide anion radical.

Conclusion:

Both 1-Ferrocenylmethylthymine and 1-Ferrocenylmethylcytosine showed
higher antioxidant activity (0.34 ± 0.03 and 0.045 ± 0.02 mg/mL respectively) than that of
standard antioxidant α-tocopherol (3.04 ± 0.03 mg/mL). The value of the binding free energy
ranging from -16.1 kJ.mol-1 for 1-ferrocenylmethylthymine to -21.8 kJ.mol-1 for 1-
ferrocenylmethylcytosine suggests an electrostatic interaction of superoxide anion radical
with both compounds which has been found to be the dominant interaction mode. The kinetics
of the interaction reaction of the compounds was quantified having second-order rate
constant values equal to 4.0 and 16.5 M-1 s-1 respectively.
The Memoirist against History: Nabokov’s Speak, Memory as the (re)negotiation of a literary form at the intersection of personal experience and historical narrative
Authors: Sala Michael
Published: April 2019

Nabokov’s Speak, Memory is a literary memoir that negotiates the relationship between history and personal experience by illuminating one end of a spectrum of authoritative effects that range from artifice to spontaneity. In using play to leverage and highlight the tension between the artifice of a work of literature and the spontaneity of personal expression (or sense making on an individual level,) and by implicating both reader and writer within that tension, it demonstrates how literary memoir can negotiate its relationship to its genre. There are thus two forms of negotiation at work in Speak, Memory, the one between artifice and spontaneity, the other between individual experience and historical narrative. In this way, by using play to invite the reader into the interpretative act, Nabokov emphasises the role of artifice in the autobiographical project, and, by doing so, stakes out a claim for the literary autobiographical writer in the face of historical narrative.

Radiology now plays a major role to diagnose, monitoring, and management of several diseases; numerous diagnostic and interventional radiology procedures involve exposure to ionizing radiation.

OBJECTIVE

This study aimed to discover and compare the awareness level of radiation doses, protection issues, and risks among radiology staff in Jeddah hospitals.

METHODS

A cross-sectional survey containing 25 questions on personal information and various aspects of radiation exposure doses and risks was designed using an online survey tool and the link was emailed to all radiology staff in eight tertiary hospitals in Jeddah. The authors were excluded from the study. A P-value of < .05 was used to identify statistical significance. All analyses were performed using SPSS, version 21.

RESULTS

Out of 156 participants the majority 151 (96.8%) had poor knowledge score, where the mean scores were 2.4±1.3 for doses knowledge, 2.1±1.1for cancer risks knowledge, 2.3±0.6 for general information, and 6.7±1.9 for the total score. Only 34.6% of the participants were aware of the dosage of a single-view chest x-ray, and 9.0% chose the right answer for the approximate effective dose received by a patient in a two-view. 42.9% were able to know the correct dose of CT abdomen single phase. There is a significant underestimation of cancer risk of CT studies especially for CT abdomen where only 23.7% knew the right risk. A p-value of <0.05 was used to identify statistical significance. No significant difference of knowledge score was detected regarding gender (P =.2) or work position (P=.66).

CONCLUSIONS

Our survey results show considerable inadequate knowledge in all groups without exception. We recommended a conscientious effort to deliver more solid education and obtain more knowledge in these matters and providing periodic training courses to teach how to minimize the dose of radiation and to avoid risk related.

La introducción de las tecnologías de la información y comunicación (TIC) ha provocado cambios en todos los ámbitos en la sociedad actual. En particular en la educación, donde la gestión del aprendizaje se ha visto impactada significativamente debido a la presencia de las TIC en el aula, y ha derivado el surgimiento de propuestas ilimitadas dirigidas a la mejora de los resultados académicos. Es por ello que la educación en esta era digital demanda prácticas innovadoras que permitan la transferencia del conocimiento a través de la incorporación de tecnología, con el fin de mejorar la calidad de los procesos de enseñanza y de aprendizaje. Esta situación plantea un gran reto para los docentes quienes afrontan el desafío de implementar nuevas estrategias para fortalecer dichos procesos. Del mismo modo, las instituciones educativas tanto de nivel medio superior como de nivel superior se han visto obligadas a propiciar la utilización de la tecnología por los docentes para la impartición de sus cursos con el objetivo de mejorar los resultados académicos.

Por lo antes dicho, este documento detalla el enfoque de aula invertida como una propuesta innovadora con base en los hallazgos de una investigación cuantitativa con diseño cuasiexperimental y alcance descriptivo, realizada en el contexto de una institución educativa de nivel medio superior de orden público en el estado de Nuevo León, cuyo objetivo se ubicó en conocer si el uso de material multimedia impacta favorablemente en el rendimiento académico y en las actitudes de los alumnos del área de las ciencias.
STEPS: propuesta de un modelo para la tutoría en línea
Authors: Villanueva Rita
Published: April 2019

Es importante que el tutor en línea conozca las áreas en las que debe intervenir y saber de qué manera lo realizará para conseguir los objetivos planteados. La supervisión del tutor es una actividad que apoya y orienta el desempeño de los alumnos y asesores en las diferentes actividades académicas en los cursos en línea.
 El tutor debe mantenerse en comunicación continua con los alumnos y asesores a través de las diferentes herramientas que ofrece esta modalidad educativa: el mensajero, el foro, el chat, las video llamadas y, en su caso, el teléfono. Todas estas acciones permiten la intervención oportuna con la información recabada en apoyo a la toma de decisiones que impactan de manera directa en el mejor rendimiento del alumno. La comunicación entre alumno, tutor y asesor debe basarse en el esquema que denominado STEPS, dado que dicho esquema permite retroalimentar de manera oportuna las diferentes actividades que rodean la vida académica de alumnos y asesores, todo lo cual se detalla en el presente artículo. Asimismo, se propone su adopción en el Bachillerato a Distancia de la UNAM (B@UNAM).

Estrategias educativas para mejorar el aprendizaje del alumno en el módulo ‘Técnicas de Estudio en Ambientes Virtuales’
Authors: Hernández García Verónica , González Hernández Blanca Rosa , Andrade Guevara Cristina
Published: April 2019

Como institución, resulta de suma importancia ofrecer un apoyo extra al estudiante que incursiona en este ambiente virtual de aprendizaje, con el fin de que cuente con las herramientas y habilidades necesarias para culminar sus estudios de bachillerato. 

Por lo anterior, en la Universidad Virtual del Estado de Guanajuato (UVEG) se considera, dentro de la trayectoria curricular, el Módulo Técnicas de Estudio en Ambientes Virtuales, el cual tiene como propósito que los estudiantes ‘se cambien el chip’ del ambiente presencial al virtual. 

Al ser parte fundamental del desarrollo de sus ‘habilidades virtuales’, este Módulo se reviste de una importancia particular al estar diseñado para ayudar a los estudiantes a lograr aprendizajes prácticos que les serán útiles durante la educación media superior. 

Debido a lo anterior y a la importancia de esta asignatura, el porcentaje de aprobación y los índices de inactividad son indicadores vitales para el seguimiento de los estudiantes que comienzan en este modelo. Esta investigación se enfoca en las estrategias que se han establecido para incrementar dichos indicadores.
Acompañamiento a estudiantes del Bachillerato UDG virtual desde el programa institucional de tutoría
Authors: Godínez González Luz Del Carmen , Ochoa Reynoso Rosa Marcela , Matías Hernández Reymundo
Published: April 2019

La tutoría, entendida como un proceso de acompañamiento con los estudiantes a lo largo de su trayectoria académica desde una perspectiva de formación integral, puede aportar elementos de valor e impacto no sólo en los indicadores de retención, acreditación y eficiencia terminal de un programa educativo, sino también en la experiencia personal de aprendizaje. 

En el presente trabajo exponemos la experiencia de tres tutores de trayectoria con estudiantes del Bachillerato General por Áreas Interdisciplinarias, en opción virtual. 

La acción tutorial, como proceso de acompañamiento cercano, oportuno, claro y pertinente con los estudiantes, a través de estrategias que promuevan el desarrollo de habilidades y talentos, regulación del proceso de aprendizaje y generación de redes de apoyo entre los estudiantes, favorece la experiencia educativa y el desarrollo de aprendizaje y competencias en nuestros tutorados.
El uso de redes sociales en el aprendizaje a distancia: metasíntesis
Authors: Mnkandla Ernest , Minnaar Ansie
Published: April 2019

La aceptación de las redes sociales en el aprendizaje en línea supone el final de la educación a distancia como la conocemos en la educación superior, aunque en apariencia han tenido un impacto mínimo en la forma en que las instituciones de educación abierta y a distancia (ODL, por sus siglas en inglés) están funcionando. Investigaciones anteriores sugieren que parte de la explicación para la lentitud en la aceptación de las redes sociales en el aprendizaje en línea está más allá de factores convencionales atribuidos a las reformas en la educación a distancia. 

Esta investigación utiliza el marco conceptual para el aprendizaje en línea (OCL, por sus siglas en inglés) en la educación superior. Las redes sociales como los blogs, las wikis, el Skype y Google Hangouts, Facebook e incluso aplicaciones móviles como WhatsApp, podrían facilitar el aprendizaje y la creación de conocimiento en

el aprendizaje en línea para las instituciones de educación superior. 

Nuestra metasíntesis es una integración interpretativa de los resultados de investigaciones cualitativas evaluadas por pares acerca de las redes sociales en el aprendizaje en línea. Incluye una síntesis de datos, métodos de investigación y teorías utilizadas para investigar redes sociales dentro de la educación en línea. Siete temas surgieron a partir de estos datos, los cuales han sido reformulados en un marco enfocado a redes sociales en el aprendizaje en línea como el producto final. El marco propuesto podrá ser útil para los diseñadores instruccionales y académicos que estén interesados en utilizar teorías de aprendizaje modernas y deseen adaptar las redes sociales en el aprendizaje en línea dentro de la educación superior como una estrategia de aprendizaje profundo.

As unidades semânticas básicas em proposta de redação do ENEM e nos textos dos alunos
Authors: Gomes Lauro
Published: April 2019

Esta pesquisa tem o objetivo de resumir os textos que compõem a proposta de redação do Enem 2011, para explicitar a ideia central de cada um deles e ver a relação que mantêm com o tema proposto para redação, e resumir duas dissertações também para ver sua ideia central e a relação com a proposta. Cumpre referir que, para isso, os textos serão analisados a partir de suas unidades semânticas básicas à luz de princí­pios e onceitos da Teoria dos Blocos Semânticos, proposta por Carel (1995) e de estudos feitos por Graeff (2012) sobre a conexão entre os enunciados no texto – por contiguidade e por similaridade. O trabalho permitiu perceber em que medida as unidades semânticas básicas presentes nas redações se relacionam com os textos motivadores que compõem a proposta de redação e em que proporção elas se relacionam aos conhecimentos prévios que os alunos adquiriram ao longo de sua formação, na escola e/ou fora dela. Em última análise, também foi possí­vel obter dados a respeito das competências e habilidades sociodiscursivas dos alunos, isto é, neste caso, de suas capacidades inerentes à leitura e à escrita.
O ensino de literatura na Educação Básica: da crise da perspectiva tradicional ao desenvolvimento de novos paradigmas metodológicos
Authors: Aguiar Marta , Suassuna Lí­via
Published: April 2019

Este artigo, de cunho teórico, constitui uma das partes de nossa dissertação de mestrado em Educação pela UFPE, mais especificamente aquela que aborda o ensino de Literatura na Educação Básica. Apresentamos, primeiramente, o contexto que originou as crí­ticas ao paradigma historicista e que levou à valorização de um modelo de ensino preocupado com a formação do leitor de textos literários. Em seguida, procuramos discutir mais detalhadamente as propostas metodológicas de Bordini e Aguiar (1993), por sua forte influência na década de 1990 e pelas considerações significativas que trazem para o ensino de Literatura, e de Cosson (2006) e Cosson e Paulino (2009), devido ao espaço vem ganhando a discussão em torno da ideia de letramento literário neste iní­cio do século XXI. Nosso estudo também busca refletir sobre as contribuições da Teoria da Literatura para o ensino na Educação Básica, tendo em vista que a construção de um percurso metodológico para o ensino de qualquer objeto não pode se dar fora de uma articulação com o campo teórico.
A representação do inglês/lí­ngua estrangeira como "matéria escolar" e alguns de seus efeitos nas práticas pedagógicas
Authors: Fortes Laura
Published: April 2019

Em nossa pesquisa de Mestrado, analisamos as concepções de "erro" no dizer de professores de inglês/lí­ngua estrangeira atuando em uma escola pública e em uma escola de idiomas. O estudo da materialidade linguí­stica desses enunciados pela perspectiva teórico-metodológica da Análise de Discurso de linha pecheutiana permitiu o delineamento de duas representações predominantes: a da lí­ngua inglesa como gramática e a da lí­ngua como instrumento de comunicação. Neste artigo, nos dedicaremos especialmente à análise da representação do inglês/lí­ngua estrangeira como "matéria escolar", que interpretamos em nossa pesquisa como um desdobramento da representação da lí­ngua como gramática. Nossa análise discursiva da representação da lí­ngua inglesa como matéria escolar procurou mostrar como o "erro" é geralmente significado num espaço de interdição para o sujeito, ou seja, significa um "desvio" pelo qual a norma é definida e reforçada e passa a ser desejada pelo sujeito como o ideal a ser alcançado. Concluí­mos que, ao funcionar no imaginário do sujeito-professor, essa representação opera na regulação dos sentidos e dos processos identitários produzidos em sua relação com a lí­ngua, com as práticas pedagógicas e com o sujeito-aprendiz.
