Authors: Aihie Osenweugwor Ngozi , Ohanaka Blessing Ijeoma
Published: May 2019

The purpose of the study was to investigate the levels of perceived academic stress among undergraduate students in a University in Nigeria. Purposive sampling was used to select three Faculties from the fourteen Faculties in the University. Simple random sampling was used to select 427 undergraduate students from the three Faculties to participate in the study. Data on perceived academic stress were collected with the aid of the Perceived Academic Stress Scale (PASS) which was adapted from Bedewy and Gabriel (2015) and re-validated for the study. Data collected for the study were analysed with descriptive and inferential statistics. The perceived academic stress levels of the respondents were compared on the basis of sex, age, level /year of study and Faculty /course of study. The hypotheses formulated for the study were tested at 0.05 level of significance. The findings revealed that male undergraduate students reported higher academic stress level than the females. Undergraduate students in the Faculty of Physical Sciences reported significantly higher academic stress levels than students in the Faculties of Education and Social Sciences. Final year students also reported higher academic stress than students in the first and middle years of study. There was no difference in perceived academic stress levels based on the age of the students. It was concluded that sex of student, level of study and course of study influence perception of academic stress among undergraduate students. Implications for Students’ counselling were discussed.
A comparison of focused and unfocused corrective feedback in Japanese EFL writing classes
Authors: Colpitts Bradley D. F. , Howard L’Shawn
Published: May 2019

Though corrective feedback (CF) has generally been accepted as an effective means for improving student writing, some debate still exists as to whether focused (narrow) or unfocused (broad) CF is more effective in improving student writing in English as a Foreign Language (EFL) contexts. A comparative study was undertaken of two groups of high-proficiency Japanese and international students of English at one private university in the Kansai area of Japan. A third control group who did not partake in any corrective feedback were also used for comparison. Both groups of students wrote argumentative essays on a subject of their choosing over the course of eight weeks. The first group, Treatment Group A, was comprised of seven Japanese and non-Japanese university students (n = 7) who were trained in giving meta-linguistic (error coded), computer-mediated unfocused peer CF. The second group, Treatment Group B, was comprised of seven Japanese university students (n = 7) who were trained in giving meta-linguistic, computer-mediated focused feedback on five errors identified as being the most common in an initial diagnostic writing sample done in the first week. The initial draft, post-peer CF draft, post-teacher CF draft, and final draft were then analyzed. Students’ ability to correctly resolve errors, and the number of errors per 100 words that emerged in each draft were then examined. The results suggest that unfocused peer and teacher CF may be a more effective means of reducing student errors in writing, possibly because it provides more overall learning opportunities.
Mobile-assisted learning and higher-education ESP: English for physiotherapy
Authors: Pettersson Lin Elinor
Published: May 2019

The popularity of Mobile-assisted language learning has increased significantly in recent years, and language teachers are still exploring different ways of introducing new technology into the language classroom. Up to the moment, this has mainly been achieved through the use of mobile language-learning applications (Grimshaw et al. 2017). We wanted to push the use of applications in the classroom of English for Specific Purposes further by introducing a human anatomy application in the context of English for physiotherapy in higher education. We believe that the use of an application for a specific area provides the opportunity to enrich the learning experience and take language-learning outcomes to a different level as students are granted a unique occasion of applying knowledge acquired in a specialist area in the language classroom. An intervention proposal was designed for the subject English for physiotherapy (University of Málaga, Spain) bringing together mobile-assisted language learning with a task-based approach to suit constructivist learning processes and accommodate different learning styles and rhythms. We followed five guiding principles on mobile-assisted language learning (Stockwell & Hubbard 2013) to design three tasks for autonomous and collaborative learning using the application 3D4 Medical Essential Anatomy. A preliminary survey was carried out using Lime Survey to measure under-graduate physiotherapy students’ attitudes towards the use of a human anatomy application to learn English and to predict possible challenges (language, technology, cost or storage capacity). The results support our belief as the obtained data indicates that students perceived the use of a human anatomy application as an interdisciplinary tool for both educational and professional purposes and were willing to purchase an application to learn English for physiotherapy.

Published: May 2019

Introduction. Currently, vegetable oils are used not only for consumption but also for medicinal and cosmetic purposes. They are especially eagerly used by women, although their knowledge in this field is usually insufficient.

Aim. The aim of the study was to determine the dietary habits of women and to analyse the importance and position of vegetable fats in their diet and life. Another objective was to assess the level of knowledge and awareness of the health-enhancing properties of these products.

Material and methods. The study involved women (n=253) aged 18-30, 31-40, and over 40 years living in Lubelskie Province, Poland. The modified questionnaire was composed of questions about their diet, regularity of meals, habits and preferences of fat intake, and motivation behind including fats in the diet or for cosmetic or medicinal applications.

Results. Approximately 45% of the respondents sometimes used fats with their meals and 23% used them regularly. Fats were consumed by approximately 86% of the total number of respondents and were used for medicinal and cosmetic purposes by ca. 15.5 % and 6% of the respondents, respectively. Linseed oil (34%) and coconut oil (27%) were regarded as the most valuable fats. Butter and rapeseed oil were consumed most frequently (p<0.05). Approximately 47% of the respondents regarded refined oils as valuable products, and 40% of the respondents were aware of the harmful effects of trans fats.

Conclusion. The survey indicates a necessity of implementation of educational campaigns among consumers in order to disseminate the knowledge about the role of fat in the diet and the risks associated with excessive consumption and poor quality of these products.
A Causality Analysis of the Relationships Between Gross Fixed Capital Formation, Economic Growth and Employment in South Africa
Authors: Meyer Daniel Francois , Sanusi Kaseem Abimbola
Published: May 2019

In terms of macro-economic policy, gross fixed capital formation, which is the major component of domestic investment, is seen as an important process that could accelerate economic growth. This study re-examines the controversial issue of causality between domestic investment, employment and economic growth using South African data. The traditional assumption of causality running from investment to economic growth has remained inconclusive while empirical findings on the investment and employment growth nexus are also largely unsettled. The study makes use of quarterly data from 1995Q1 to 2016Q4 within the framework of the Johansen cointegration and Vector Error Correction Models (VECM). The empirical findings suggest that a long run relationship exists between domestic investment, employment and economic growth, with causality running from economic growth to investment and not vice versa. The results also demonstrate that investment has a positive long-run impact on employment. The empirical evidence further suggests bi-directional causality between employment and economic growth, while evidence of uni-directional causality, from investment to employment, is also found. The major implication of the study is that although there is bi-directional causality between economic growth and employment, economic growth does not translate to increased employment in the long run confirming “jobless growth”. Investment is found to be a positive driver of employment in the South African economy in the long-run. The study concludes that, in order to stimulate employment, investment enhancing policies, such as low interest rates and a favourable economic environment should be put in place to accelerate growth. Measures to promote economic growth, such as improved infrastructural facilities and diversification of the economy, should be further engineered so as to encourage increased investment.

Published: May 2019

Taking into consideration the results of our clinical observation, we can argue that the technique of endoscopic submucosal dissection of large leiomyoma of the esophagus with subsequent closure of the defect with a mucosal flap is applicable in clinical practice. This method is relatively safe, allows to achieve complete, quality results of morphological study, helps to reduce the number of postoperative complications, compared to more invasive surgical interventions. Also it reduces the time of social recovery and contributes to preserving the quality of life after the treatment.

Abstrak            Penelitian ini ditujukan untuk mengetahui dan menganalisa faktor-faktor yang mempengaruhi perilaku beralihnya nasabah tabungan Britama ke tabungan bank lain. Analisis regresi linier berganda digunakan untuk menguji lima variabel bebas yaitu reputasi bank, kualitas layanan bank, daya tarik iklan bank, harga dan involuntary switching terhadap customer churn. Data penelitian berasal dari 100 responden eks nasabah Britama yang tinggal di wilayah Greater Jakarta (Jakarta, Bogor, Depok, Tangerang dan Bekasi). Hasil penelitian menunjukkan bahwa reputasi bank, kualitas layanan bank, daya tarik iklan bank dan harga berpengaruh signifikan secara negatif, sedangkan involuntary switching berpengaruh signifikan secara positif terhadap tingkat churn tabungan Britama. Reputasi bank, kualitas layanan bank, daya tarik iklan bank dan harga akan menghambat terjadinya peralihan nasabah dan meminimalisir tingkat churn tabungan. Sebaliknya, involuntary switching justru akan mendukung beralihnya nasabah dan meningkatkan churn tabungan.CHURN LEVEL OF SAVINGS IN THE BANKING INDUSTRYAbstract            This study aims to determine and analyze the factors that influence customer switching behavior of Britama savings to other bank savings. Multiple linear regression analysis will be used to examine the independent variables such as bank reputation, bank service quality, attractiveness of bank advertisement, price and involuntary switching that influence customer churn. The data of this research were obtained from 100 respondents of former Britama that live in Greater Jakarta area (Jakarta, Bogor, Depok, Tangerang and Bekasi). The result shows that bank reputation, bank service quality, attractiveness of bank advertisement have significant influence negatively, while involuntary switching positively significant influence to Britama savings churn. Bank reputation, bank service quality, attractiveness of bank advertisement and price will prevent the customer switching behavior and minimize customer churn. Instead, involuntary switching will support the customer switching behavior and increase savings churn.

AFRO-PENTECOSTALISM AND CONTESTED HOLINESS IN SOUTHERN AFRICA
Authors: Chimuka Tarisayi Andrea
Published: May 2019

The proliferation of charismatic and Pentecostal movements in southern Africa, and indeed the whole continent of Africa, as well as the recurrent competition for recognition and authenticity makes one astounded regarding the direction in which Christianity in Africa is developing. Is this connected to the historic Pentecost recorded in the second chapter of the book of Acts? If it is, why are there acrimony, strife and rivalry among the various members of the Christian body? This paper hypothesises the possibility of a parallel idea of holiness in African traditions which undergirds some of these religious movements and in turn challenges the idea of authenticity in African Christianity. If the various movements are somehow tapping into African traditions for miracle working power, does this suggest that the said traditions are alternative axils of holiness? Would this, by implication suggest that Christianity in Africa can be anchored thereon?
Large Eddy Simulations with Conjugate Heat Transfer (CHT) modeling of Internal Combustion Engines (ICEs)
Authors: Wu Angela , Keum Seunghwan , Sick Volker
Published: May 2019

In this study, the effects of the thermal boundary conditions at the engine walls on the predictions of Large-Eddy Simulations (LES) of a motored Internal Combustion Engine (ICE) were examined. Two thermal boundary condition cases were simulated. One case used a fixed, uniform wall temperature, which is typically used in conventional LES modeling of ICEs. The second case utilized a Conjugate Heat Transfer (CHT) modeling approach to obtain temporally and spatially varying wall temperature. The CHT approach solves the coupled heat transfer problem between fluid and solid domains. The CHT case included the solid valves, piston, cylinder head, cylinder liner, valve seats, and spark plug geometries. The simulations were validated with measured bulk flow, near-wall flow, surface temperature, and surface heat flux. The LES quality of both simulations was also discussed. The CHT results show substantial spatial, temporal, and cyclic variability of the wall heat transfer. The surface temperature dynamics obtained from the CHT model compared well with measurements during the compression stroke, but the absolute magnitude was 5 K (or 1.4%) off and the prediction of the drop in temperature after top dead center suffered from temporal resolution limitations. Differences in the predicted flow and temperature fields between the uniform surface temperature and CHT simulations show the impact of the surface temperature on bulk behavior.

PRIMER MOLAR SUPERIOR. EVALUACIÓN Ex VIVO DE LA PRESENCIA DEL CONDUCTO MEDIO-PALATINO
Authors: Szwom Ruben Jaime , Guardiola María de los Ángeles , Serpa Idelma
Published: May 2019

El primer molar superior es la pieza dentaria que posee la mayor cantidad de variaciones morfológicas en sus conductos radiculares, tanto en forma como en cantidad de los mismos. Según diversos estudios realizados se estipula que el 70% de la población posee cuatro conductos en sus primeros molares superiores. Esto se debe a la presencia de un achatamiento en sentido mesio distal de la raíz mesio vestibular lo que significa que esta raíz presente dos conductos radiculares, uno mesio vestibular, también denominado MB1 y otro medio palatino, también llamado MB2. Ambos pueden confluir en un solo foramen apical o bien finalizar en forma independiente. El objetivo de este pequeño trabajo de investigación, ex vivo, es que los alumnos de 5º año de la Facultad de Odontología del Instituto Universitario Italiano de Rosario aprecien la prevalencia en los primeros molares superiores de este conducto medio palatino, su permeabilidad y la importancia de una buena limpieza y conformación de ambos conductos en esta raíz para lograr el éxito del tratamiento endodóntico. Se trabajaron con 18 Primeros Molares Superiores a los cuales se les realizó una radiografía periapical ortorradial y a partir de este paso se comenzó a trabajar en la Endodoncia de esta pieza dentaria. En este trabajo se obtuvo que el 27,8% de las piezas dentarias presentaron el conducto medio palatino y el 72,2 % no presentaban el mismo. Del 27,8 %, 5,56 % finalizaban en diferentes forámenes apicales mientras que el 22,2 % finalizaban en el mismo.
É possível falar de deus na época do niilismo?
Authors: Tosi Giuseppe
Published: May 2019

o artigo problematiza a questão que lhe serve de título: é possível falar de Deus na época do niilismo? O ponto de partida é o reconhecimento do niilismo como “destino”, “cifra”, “espírito” do nosso tempo, ou seja, o início de uma época de decadência, mudança e desvalorização de todos os valores que provoca a chamada “crise dos paradigmas” religiosos, metafísicos, ético-políticos, estéticos e epistemológicos. Esta crise, porém, não deixa um mero vazio: os paradigmas perdidos foram substituídos por um novo que está se tornando dominante, que é o paradigma técnico-científico. A crítica à técnica enquanto destino do nosso tempo está levando a duas posturas opostas: ora para uma impossível volta ao passado, ora para uma atitude de impotência para com o futuro. Após analisar várias alternativas possíveis para um discurso racional sobre Deus, no interior e para além do niilismo, o autor conclui que a religião, apesar de todas as críticas, tem uma grande chance de sobreviver porque o sentimento religioso é uma dimensão originária da condição humana e porque os seres humanos precisam de fortalecer os laços de identidade e solidariedade orgânica e de segurança diante do mistério e dos perigos do mundo. Mas a religião (em particular a cristã) precisa se reinventar profundamente aceitando as “lições” do niilismo: assumir uma postura mais prudente contra o fundamentalismo, o dogmatismo, o fanatismo, a intolerância, a violência; não fazer de Deus um objeto a ser manipulado para os nossos interesses “mundanos”; e renovar o grande e insuperável legado ético do cristianismo, que se manifesta mais na ortopraxis do que na ortodoxia. Talvez seja este o caminho mais promissor para “falar de Deus na época do niilismo”.

A New Tool for Validating Theoretically Derived Anisotropic Displacement Parameters with Experiment: Directionality of Prolate Displacement Ellipsoids
Authors: Mroz Damian , George Janine , Kremer Marius , Wang Ruimin , Englert Ullrich , Dronskowski Richard
Published: May 2019

X-ray diffraction on crystalline solids provides the electron density in the unit cell, typically interpreted as atom types, fractional coordinates, and anisotropic displacement parameters (ADPs). Given the chemical composition, not only coordinates but also ADPs can be obtained from first-principles calculations. In order to validate the latter, we suggest comparing the direction of the maximum main axes for sufficiently anisotropic theoretical and experimental ellipsoids, in addition to their scalar properties. This new criterion provides additional insight: while the amplitude of motion is generally underestimated by the computationally inexpensive harmonic approximation, the relative orientation may still be in good agreement with the experimental findings. This approach can complement the already established scatter plot of main-axes components and the similarity index, and it is also chemically intuitive by giving a direct picture of the relative orientation of the ellipsoids.
Decay Associated Fourier Spectroscopy: Visible to Shortwave Infrared Time-Resolved Photoluminescence Spectra
Authors: Atallah Timothy , Sica Anthony , Shin Ashley , Friedman Hannah , Caram Justin
Published: May 2019

We describe and implement an interferometric approach to decay associated photoluminescence spectroscopy, which we term decay associated Fourier spectroscopy (DAFS). In DAFS, the emitted photon stream from a substrate passes through a variable path length Mach-Zehnder interferometer prior to detection and timing. The interferometer encodes spectral information in the intensity measured at each detector enabling simultaneous spectral and temporal resolution. We detail several advantages of DAFS, including wavelength-range insensitivity, drift-noise cancellation, and optical mode retention. DAFS allows us to direct the photon stream into an optical fiber, enabling the implementation of superconducting nanowire single photon detectors for energy-resolved spectroscopy in the shortwave infrared spectral window (λ=1-2 μm). We demonstrate the broad applicability of DAFS, in both the visible and shortwave infrared, using two Förster resonance energy transfer pairs: a pair operating with conventional visible wavelengths and a pair showing concurrent acquisition in the visible and the shortwave infrared regime.

Mediastinal gray-zone lymphoma (MGZL, lymphoma with features intermediate between classical Hodgkin lymphoma and diffuse large B-cell lymphoma) was declared as a separate entity in WHO classification of Tumors of Haematopoetic and Lymphoid Tissues in 2008 and 2017 years. Despite of similar pathomorphological characteristics between primary mediastinal B-cell lymphoma and Hodgkin lymphoma, clinical features and optimal therapeutic approach to MGZL are not clearly defined. Usually MGZL manifests with mediastinal lymphadenopathy, although extranodal lesions often occur (grey-zone lymphoma, GZL). Patients with MGZL have unfavorable prognosis, taking into account high rate of relapse. This article describes two cases of MGZL. First case manifested by arrhythmias due to primary heart involvement. In spite of cardiac failure antracycline-containing chemotherapy (6 courses of R-DA-EPOCH) it allowed to achieve a complete remission and resolving of arrhythmias. Second case was represented by metachronous tumors: primary mediastinal B-cell lymphoma at the time of disease onset and classical Hodgkin lymphoma, NS II, diagnosed after disease progression. Thus, we demonstrated two examples of MGZL that differ by clinical manifestation, response to chemotherapy, which emphasizes an importance of pathogenesis studying, and using of new therapeutic approaches.

Published: May 2019

Hereditary hemochromatosis (HH) is a disease with an autosomal recessive hereditary type, stipulated by the genetic defect that leads to a high intestinal absorption of iron and primary accumulation in the parenchymal cells of the liver and other organs. This is the most common hereditary disease among White population, the frequency is about 1 case per 250 people. The prevalence of HH is inhomogeneous, people from countries in Northern Europe, especially Scandinavian, are more susceptible to this disease. Mutations of the HFE gene account for approximately 90% of HH cases. In HH excess iron deposits mainly in the cytoplasm of parenchymal cells of various organs and tissues: in the liver, pancreas, endocrine glands, skin and joints. The clinical picture of HH is characterized by the classical triad development: cirrhosis of the liver, diabetes mellitus (DM) and hyperpigmentation. HH may also manifest itself as various endocrinopathies (hypofunction of hypophysis, adrenal glands, thyroid gland, arthropathy, cardiomyopathy). Diagnostics of HH is based on the determination of the iron metabolism values: serum iron, transferrin saturation, the amount of ferritin, the genetic tests, liver biopsy data are used to confirm the diagnosis. Despite the fact that HH is a well-studied disease, in some cases it is complicated to diagnose it. Developed posthemorrhagic anemia in a patient is one of such reasons when the iron metabolism test is not informative.

Sarcoidosis is a multisystem granulomatous disease of unknown etiology. Liver is frequently involved in the pathological process. Wide range of clinical manifestations can be seen: from asymptomatic lesion with normal liver function tests to cirrhosis with portal hypertension. Biopsy plays the key role in diagnosis of the hepatic sarcoidosis. It is essential for morphological diagnosis to exclude other causes of granulomatous liver disease, most often - primary biliary cholangitis. Nowadays there are no standard treatment protocols for patients with hepatic sarcoidosis.

Obesity is closely associated with metabolic and cardiovascular diseases, including dyslipidemia, coronary artery disease, hypertension, and heart failure. Adipose tissue (AT) is identified as a complex endocrine organ, with a wide range of regulatory functions at the cellular, tissue and systemic levels. Various terms, including paracardiac, epicardial and pericardial, are used to describe the fatty deposits surrounding the heart. Among all the fat depots, perivascular AT (PVAT) is of great biological significance for the cardiovascular system due to its anatomical proximity to the vessels. Recent studies have shown the presence of a complex, bidirectional paracrine and vasocardial signaling system between the vascular wall and PVAT. In the review, we will discuss the biological role of PVAT in both the physiological state and cardiovascular pathology, emphasizing its dual proatherogenic and antiatherogenic role. Let us consider PVAT as a target for various therapeutic agents in cardiovascular diseases. We will also analyze data on the role of non-invasive techniques as a diagnostic tool for assessing coronary artery inflammation.

Aim. To evaluate standard 12-lead ECG indices for the differential diagnosis of wide QRS tachycardias with right bundle branch block (RBBB) pattern. Materials and methods. Study analyses the 244 ECG indices in 111 patients (79 males and 32 females, age 53±17 years) with RBBB tachycardias, who underwent electrophysiological studies. First step includes retrospective analysis of QRS characteristics in 20 patients with ventricular tachycardias (VT), 24 pts with aberrant supraventricular tachycardias (SVT+RBBB) and 14 pts with antidromic SVTs (WPW). ROC- and multifactorial analyses were performed to develop diagnostic ECG algorithms. The prognostic accuracy of the algorithms was subsequently evaluated on a prospective group of patients with RBBB tachycardias (n=53). Results and discussion. ECG criteria of RBBB VTs were: 1) the presence Q-wave in lead II, 2) the duration interval R(peak)-S(end) >100 ms in lead V5. ECG criteria for antidromic SVTs with RBBB were: 1) the duration of the R wave in lead I ≥80 ms, 2) the absence of split (M-sharp) R-waves in lead V2, 3) the absence notch in ascending S wave in lead aVL. The accuracy of the algorhythm for diagnostic of VTs with RBBB was 83% (sensitivity 100%, specificity 73%). The accuracy of the algorhythm for diagnostic of antidromic SVTs with RBBB was 91% (sensitivity 85%, specificity 96%). Conclusion. The proposed algorithms are based on new ECG criteria for the differential diagnosis of wide QRS complexes tachycardias with RBBB pattern, unlike the previous algorithms.
A TRADUÇÃO COMO RECURSO EM ATIVIDADES DE UM LIVRO DIDÁTICO DE LÍNGUA INGLESA
Authors: Araújo Angélica Almeida de , Branco Sinara De Oliveira
Published: May 2019

Este trabalho tem o objetivo de analisar atividades propostas em um livro didático de língua inglesa como língua estrangeira que abordem categorias de tradução. A partir da análise das atividades foi possível perceber o uso frequente de recursos tradutórios que auxiliam no aprendizado de língua estrangeira (LE). Esta pesquisa está fundamentada na Abordagem Funcionalista de Tradução e nas Categorias de Tradução. As atividades foram selecionadas levando em consideração as categorias de tradução. A análise demonstrou que o uso da tradução por meio das categorias intralingual e interlingual não é tão explorado no nível inicial de aprendizado de língua inglesa. Identificou-se que o uso mais recorrente no material investigado é o da categoria de tradução intersemiótica, representando 82% de frequência nas atividades analisadas. Conclui-se que, no nível básico de aprendizado de LE, o uso de imagens, fotos, cores e demais elementos não verbais são um auxílio fundamental para o desenvolvimento de língua inglesa.
AS FIGURAS DE LINGUAGEM E SUAS TRADUÇÕES EM NOTRE-DAME DE PARIS:
Authors: Silva Jocileide
Published: May 2019

As figuras de linguagem são recursos estilísticos que podem enriquecer um texto. Victor Hugo, no capítulo “Lasciate ogni speranza” (“Deixai toda esperança”), da obra Notre-Dame de Paris, faz uso desse recurso para descrever o escuro, o terrível e o monstruoso espaço da masmorra, na qual Esmeralda foi presa. Objetiva-se aqui analisar as figuras de linguagem presentes no texto-fonte e que servem para caracterizar esse ambiente e, posteriormente, traduzi-las, a fim de verificar sua permanência e adequação no texto-alvo. Essa análise se apoiará nos estudos de Pierre Fontanier sobre as figuras de linguagem, e nos estudos de Paul Ricœur e Marivonne Boisseau, no que se refere à tradução. Para abordar o grotesco e a monstruosidade, partiremos das reflexões de Victor Hugo, Edmond Burke e Claude Kappler.
ANALISANDO PADRÕES DE COLOCADOS COMO TRAÇOS DO ESTILO DA TRADUÇÃO:
Authors: Castro Mayelli Caldas de , Montenegro Marina Sampaio

Neste estudo exploratório descreve-se o estilo de duas traduções de Heart of Darkness (CONRAD, 1902), uma espanhola (FOLCH, 2007) e uma do português europeu (RODRIGUES, 2009), usando um corpus paralelo. O estudo tem como aporte teórico os estudos de estilo da tradução e utiliza a metodologia dos Estudos da Tradução Baseados em Corpus – ETBC. Toma-se como base Stubbs (2003, 2005), que defende o uso de informações quantitativas para um estudo mais detalhado da obra de Conrad. Stubbs (2003, 2005) afirma que um dos temas principais da obra de Conrad é realizado pela repetição de itens lexicais que denotam incerteza e impressões vagas, especialmente pelo uso elevado do lema seem* (79). Stubbs (2005) chama atenção para o fato de que o lema seem*, que não é comumente um verbo de frequência alta em textos ficcionais, está entre os 10 verbos mais frequentes na obra. Investigando-se a alta frequência do lema parec* nos dois textos traduzidos (TTs) referidos verificou-se que em Folch (2007) a frequência é maior (111) em relação ao texto fonte (TF), pois se observa que o tradutor utilizou essa forma para a tradução de outros itens que não aqueles derivados do lema seem*. Rodrigues (2009) apresenta uma frequência um pouco maior do lema parec* (126) e realiza 15 escolhas diferentes para a tradução dos itens lexicais derivados de seem*. Com base nesses dados, procura-se descrever as mudanças significativas que ocorreram no estilo dos textos traduzidos com relação ao uso do verbo parecer.
TRADUÇÃO COMENTADA DE “ALLA SERA”:
Authors: Falavina Flavia Pala
Published: May 2019

A poesia “Alla sera”, escrita pelo autor ítalo-grego Ugo Foscolo (1778-1827), além de ser considerada pela crítica um dos sonetos foscolianos mais belos, também comporta, em sua forma e tema, características dos movimentos literários neoclássico e romântico. Com o objetivo de difundir a literatura foscoliana e colaborar com os estudos italianísticos, a proposta de tradução busca transmitir a temática noturna e melancólica que atravessa o soneto “Alla sera” bem como a poética linguagem de Foscolo. Baseada em autores como Henri Meschonnic e Antoine Berman, a tradução parte de uma concepção que não separa a forma do sentido, mas que se atém ao ritmo e à sistematicidade do texto.
