Comparison of Gene Expression Between Two Types of Anti-EGFRvIII ScFv Antibodies Having Different Variable Domain Orders in Escherichia coli
Authors: Dewi Kartika Sari , Fuad Asrul Muhamad
Published: November 2018

Several studies reported that the expression of various kinds of Single-chain variable fragment (scFv) antibodies in Escherichia coli are significantly influenced by the order of their variable domains. To date, the effect of the order of variable domains in the expression of scFv antibodies against epidermal growth factor receptor variant III (EGFRvIII) has not been reported. This study aimed to compare the expression between VH-linker-VL and VL-linker-VH domain orders of the anti-EGFRvIII scFv antibodies in E. coli expression system. Recombinant plasmids inserted with DNA encoding scFv proteins were transformed into E. coli NiCo21(DE3) competent cells and characterized by colony PCR. The expression of scFv proteins was done by using optimum concentration of inducer. Total proteins, soluble periplasmic and cytoplasmic proteins, also extracellular proteins were isolated, subsequently characterized by SDS-PAGE, Slot Blot, and ImageJ software analyses. The antigen-binding activity of both scFvs proteins against EGFRvIII was observed. The results showed that the relative percentage of scFv expression with VH-linker-VL domain order is higher than that of VL-linker-VH in each compartment. Moreover, both of scFvs proteins have antigen-binding activity against EGFRvIII.
Из проблематики духовных ценностей русского православия – „Дневник писателя” эмигранта Б.К. Зайцева
Authors: Mianowska Joanna
Published: November 2018

The prose written by a representative of the First Wave of Russian Emigration – B.K. Zaytsev – has been investigated in Poland since the 1980s, and at the beginning of the 21st century we know that there are some academic centers and researchers that have dedicated their work to different aspects of the prose written by the author of ’A Writer’s Diary’. This article examines Zaytsev’s essays devoted to the spiritual values of the Russian Orthodox Church. Their essence is described in Zaytsev’s essays about John of Kronstadt or the Optina Hermitage, which is where Russian notables such as N. Gogol, V. Solovyov, K. Leontyev, F. Dostoyevsky or even L. Tolstoy himself came to seek advice. Zaytsev’s essays: ‘The history of the Russian soul’ and ‘One more time about Athos’ are very important as they provide an understanding of the values of the Russian Orthodox Church. In the latter the author contemplates his visit to the monks of Athos reminiscing about their kindness, rectitude and modesty which, according to Zaytsev, ‘calmed his own soul’.

O wyrażaniu radości (na przykładzie rosyjskich konstrukcji z predykatem „рад” i ich polskich odpowiedników przekładowych)
Authors: Czapiga Zofia
Published: November 2018

The author concentrates on the typically Russian structures with predicate рад, which expresses joy, and their Polish equivalents. It turns out that, apart from dictionary counterparts (rad, cieszyć się), also other lexemes with similar meaning (zadowolony, miło, przyjemnie) appear. As a result, sentences containing such structures are semantically similar, even if they differ syntactically. The use of some forms (e.g.: рад /miło mi) is, in some situations, a sign of obeying certain social norms of behavior.

Typologia homonimii językowej z punktu widzenia pragmatyki
Authors: Król Martyna
Published: November 2018

The paper proposes a new approach to the phenomenon of homonymy. Thetypology of homonymy was prepared from a pragmatic point of view. This is a typology related to all types of communicative acts. As a result of taking this approach, four main types of language homonymy were identified: sociolectal homonymy, discourse homonymy, ethnolinguistic homonymy and idiostylistic homonymy. The first three types were divided into more detailed categories, which resulted in dividing homonymy into: intrasociolectal and intersociolectal homonymy, intradiscourse and interdiscourse homonymy as well as intralanguage and interlanguage homonymy. Idiostylistic homonymy is an extraordinary type of homonymy and it is not divided in this way.

Housing market and labor market search
Authors: Limnios Christopher
Published: November 2018

Current models fail to concurrently account for several important empirical regularities in the housing and labor markets. I augment the Diamond-Mortensen-Pissarides (DMP) search and matching model of the labor market with a housing market characterized by search and matching frictions, integrating both markets in a coherent macroeconomic model. The model provides a framework to explain how shocks and frictions which originate in the labor market spill over into the housing market and vise versa. The model accounts for procyclical, serially correlated real estate values, rental rates and expected real estate appreciation. Further, it accounts for increases in wages, housing costs and willingness to commute as a result of increases in geographic amenities. The model is also consistent with the empirical relationship between vacancy rates in the housing market and separation rates in the labor market. Simulations demonstrate that certain land-use policies can mitigate permanent shocks to labor productivity and the level of geographic amenities.
Influence of habitat complexity on fish density and species richness in structurally simple forereef seagrass meadows
Authors: Ho Nina Ann Jin , Ooi Jillian Lean Sim , Affendi Yang Amri , Chong Ving Ching
Published: November 2018

Seagrass meadows are highly productive habitats that support commercially and ecologically important fishes and invertebrates. However, evidence of fish-habitat relationships are seldom drawn from forereef seagrass meadows that are structurally simple in terms of species richness and relative size and, consequently, their role as habitats is unclear. In this study, fish-habitat relationships were examined in such meadows in the forereef seagrasses of Tinggi Island and Babi Besar Island, Malaysia, by documenting habitat complexity attributes (canopy height, shoot density and percent cover), distance to adjacent coral reefs, and water depth within 2×2 m quadrats. Fish assemblages were recorded using the Remote Underwater Video Station method. A total of 1166 individuals from 86 taxa were found and enumerated. This study showed that (1) fish density and species richness were significantly associated with seagrass percent cover alone; (2) commercially important carnivores formed the majority of the fish populations in the meadows, and (3) fish density and species richness were positively correlated with distance to the nearest adjacent coral reef, indicating the need to account for the effects of neighboring habitats in studies of this nature. Thus, structurally simple seagrass meadows are still important fish habitats, especially as feeding grounds for commercially significant carnivores.

Norfloxacin-azole hybrids 3 and 6a,b were synthesized starting from norfloxacin. The treatment of these compounds with amines as a one-pot three-component reaction produced the corresponding amino derivatives 4a,b, 7a–g and 8a,b in good yields. The conventional and microwave-assisted methods were used with the latter method being more efficient. The structures of the synthesized compounds were characterized by elemental analysis, IR, 1H NMR, 13C NMR and MS. All compounds were screened for their antimicrobial activities. Most of them exhibit excellent antibacterial activity but are not active against selected fungi.
Slowing Down Interactions on Tangible Tabletop Interfaces
Authors: Lahure Cathia , Maquil Valérie
Published: November 2018

This paper describes the results from a comparative study with 14 pupils using two different versions of a tangible tabletop application on satellite communication. While one of the versions was designed in a way to allow the resolution of the tasks in a pure trial-and-error approach, the second version prevented this by adding a button which had to be pressed in order to calculate and display results. The results of the study show that the design of the button and the associated scoring system was indeed successful in slowing down interactions and increasing thinking time. However, the knowledge acquisition was lower for the version with the button as compared to the one supporting trial-and-error. We discuss the results of this study and, in particular, argue for the need to carefully balance usability, task complexity and the learning dimension in the design of interactive tabletops for learning.
The use of the ablative clitic in locative phrases in Iraqw, a Cushitic language of Tanzania
Authors: Kruijt Anne
Published: November 2018

This paper examines the use of the ablative case clitic in locative phrases in Iraqw, a South Cushitic language of Tanzania. In the typological classification of locative marker syncretisms, Iraqw has been classified as a language with a Source=Location≠ Goal pattern. This pattern is extremely rare in languages of the world and has been argued to be unattainable. The Iraqw ablative case clitic has been reported as both source and location marker. New data shows that the directional case clitic, a goal marker, appears on locative constructions as well, but that it is used to express purpose rather than location. The data also shows that the ablative case clitic is found mainly in locational clauses with a main verb with a durative aspect. Based on this, I argue that in locative constructions, the ablative clitic expresses duration rather than location and I propose the reanalysis of the ablative marker in locative phrases as a durational marker. The notion of location does not need to be expressed overtly, but is a zero-marker. Therefore, the rare Source=Location≠ Goal pattern is no longer valid for Iraqw, and instead I propose the pattern Source≠ Location≠ Goal, which is common in languages of the world.
My Brother’s Keeper: Assurbanipal versus Šamaš-šuma-ukīn
Authors: Zaia Shana
Published: November 2018

When Esarhaddon named his successors, he split the empire between two of his sons, with Assurbanipal as king of Assyria and Šamaš-šuma-ukīn as king of Babylonia. This arrangement functioned until 652 BCE, at which point a civil war began between the brothers. The war ended with Assurbanipal’s victory and Šamaš-šuma-ukīn’s death in 648 BCE. While Šamaš-šuma-ukīn’s death is mentioned in several of Assurbanipal’s inscriptions, it is still unclear how the king of Babylon met his end, and scholars have suggested theories ranging from suicide, assassination, execution, and accidental death. By offering a reexamination of the evidence for royal death in general and Šamaš-šuma-ukīn’s demise in particular, this article explores how possibly taboo topics such as fratricide, regicide, and suicide were depicted in Neo-Assyrian state texts and how Assurbanipal appears to have coped with his brother’s rebellion and death, especially as compared to Assyrian treatments of belligerent and rebellious foreign kings. This article argues that the relative silence around Šamaššuma- ukīn’s death is due to the fact that, while he was an enemy combatant, he was nonetheless a member of the Assyrian royal family and a legitimately-installed king. Overall, this article concludes that Assurbanipal uses several rhetorical strategies to distance himself from Šamaš-šuma-ukīn, especially invoking deus ex machina as a way to avoid even the potential accusation of fratricide and ultimately erasing his brother from the written record and Assyrian history.
Cellulose Acetate Polymeric Membrane Fabrication by Nonsolvent-Induced Phase Separation Process: Determination of Velocities of Individual Components
Authors: Rezakazemi Mashallah , Hemmati Alireza , Shirazian Saeed
Published: November 2018

In this work, the velocities of individual components during the immersion process using mathematical modeling of a nonsolvent-induced phase separation process are investigated. For this purpose, a mass average velocity correction factor was defined as the ratio of mass average velocity in the absence of a zero polymer velocity assumption to the mass average velocity with zero polymer velocity assumption. The velocities were computed and the result was coherent with observations of a considered case study. It was concluded that the polymer moves towards the interface, as the sign of the polymer velocity at early moments of immersion was positive, which is in accord with accumulation and vitrification of the polymer at the interface. The positive sign of the solvent and the negative sign of nonsolvent are in accord with the observations as solvent leaves the cast film and nonsolvent penetrates into the film. The reduction of velocity values to the order of magnitude of diffusivities is in accord with the limiting role of the rigid skin layer for mass exchanges. Relatively large velocity values of the solvent rather than the nonsolvent imply that much more solvent is probably left in the cast film rather than the nonsolvent enters into it as observed by densification of the cast film.
Effect of skin-to-skin contact on the placental separation time, mother’s oxytocin and pain levels: randomized controlled trial
Authors: Turan Zekiye , Erenel Ayten Şentürk
Published: November 2018

Objective

This study determined the effect of skin-to-skin contact (SSC) between mother and infant during the third stage of labor on postpartum levels of oxytocin and pain and placental separation time.

Methods

This randomized controlled trial was composed of 64 parturients: 32 in the intervention group and 32 in the control group. SSC interventions between infants and their mothers occurred for 30 min after birth, whereas infants in the control group were provided routine care. Data were gathered using an introductory information form, Visual Analog Scale, determination of placental separation degree form, and time and records of oxytocin analyses.

Results

There was no significant difference regarding placental separation time and 1st and 30th min oxytocin levels of mothers (p>0.05), whereas postpartum 5th, 15th and 30th min pain levels of women in the intervention group were significantly lower than women in the control group (p<0.05).

Conclusion

SSC is a valuable practice for both mother and infant, which especially reduces a mother’s pain. The study should be reiterated by excluding other variables that are likely to affect oxytocin levels.
Testing Method of Rock Dynamic Fracture Toughness Using Large Single Cleavage Semicircle Compression Specimens
Authors: Ying Peng , Zhu Zheming , Zhou Lei , Fan Yong , Dong Yuqing , Wang Meng
Published: November 2018

Dynamic fracture toughness is an important material parameter that can be applied in the prediction of a cracked structure’s stability under dynamic loads. Large single cleavage semicircle compression specimens were used to evaluate rock dynamic fracture toughness by a drop weight impact test system. Crack propagation gauges, which consist of a group of fine wires, were glued along a crack propagation path to measure crack propagation speed and propagation time. The finite difference code Autodyn (ANSYS, Canonsburg, PA) was used to simulate the crack propagation path and to analyze the crack propagation mechanism. A group of gauge points were set up along the propagation path, and the stresses at these points were calculated and analyzed. The dynamic stress intensity factors were calculated by numerical models using the finite element code ABAQUS (Dassault Systèmes, Vélizy-Villacoublay, France). Finally, the dynamic fracture toughness, including initiation toughness and propagation toughness, was determined according to crack propagation speed and propagation time. The results show that crack propagation speed varies during dynamic propagation under impact loads, and the propagation toughness is inversely proportional to the crack propagation speed. In addition, the phenomena of cracks temporarily arresting could be observed during crack dynamic propagations.

Published: November 2018

For vehicle drivetrain system parts such as gears, case hardening heat treatment with carburizing is well used to improve wear and rolling contact fatigue properties. However, distortion would occur during heat treatment processes, which may be a problem in improving the precision of the gear shape. Predicting distortion behavior accurately by heat treatment simulation method could help us achieve a good heat treatment quality and parts’ shape accuracy. In this article, heat treatment simulation that is the predicting method from cooling situation to heat treatment distortion and computer fluid dynamics that is the predicting method from flow condition to cooling phenomena are combined. This combined method can estimate heat treatment quality on mass production treatment, especially in stable flow condition or some cooling conditions. However, especially for a continuously variable transmission pulley quenched in high-speed flow oil condition, the accuracy of heat treatment simulation is lower than other conditions. We estimated this to be the effect of turbulence generated in the flow.

The effective learning can be built by comprehend the students’ prior knowledge. However, it is rare for teacher to arrange learning based on students’ alternative concepts, particularly be related to force and motion concept. Based on those problems, this research is aims to describe student’s mental model about Newton’s Third Law. The methods is testing by four essay items about to action-reaction forces. Those items asked students to explain, predict, and evaluate the phenomenon which is related to Newton’s Third Law. The sample include 140 students from 3 provinces in Indonesia, that consist of D.I Yogyakarta, South Borneo, and West Borneo. The results showed that there is many students held diverge mental model about action-reaction forces. The divergences among others are: the greater the mass, the greater the force in collision phenomenon; the resting object can’t exert reaction force; the action-reaction forces can be cancelling each other. The suggestion to overcome those mental models is discussed. We hope these result can be applied by others teachers to construct better leaning about Newton’s Third Law.

Fetal hyperglycemia acutely induces persistent insulin resistance in skeletal muscle

Published: November 2018

Offspring exposedin uteroto maternal diabetes exhibit long-lasting insulin resistance, though the initiating mechanisms have received minimal experimental attention. Herein, we show that rat fetuses develop insulin resistance after only 2-day continuous exposure to isolated hyperglycemia starting on gestational day 18. Hyperglycemia-induced reductions in insulin-induced AKT phosphorylation localized primarily to fetal skeletal muscle. The skeletal muscle of hyperglycemia-exposed fetuses also exhibited impairedin vivoglucose uptake. To address longer term impacts of this short hyperglycemic exposure, neonates were cross-fostered and examined at 21 days postnatal age. Offspring formerly exposed to 2 days late gestation hyperglycemia exhibited mild glucose intolerance with insulin signaling defects localized only to skeletal muscle. Fetal hyperglycemic exposure has downstream consequences which include hyperinsulinemia and relative uteroplacental insufficiency. To determine whether these accounted for induction of insulin resistance, we examined fetuses exposed to late gestational isolated hyperinsulinemia or uterine artery ligation. Importantly, 2 days of fetal hyperinsulinemia did not impair insulin signaling in murine fetal tissues and 21-day-old offspring exposed to fetal hyperinsulinemia had normal glucose tolerance. Similarly, fetal exposure to 2-day uteroplacental insufficiency did not perturb insulin-stimulated AKT phosphorylation in fetal rats. We conclude that fetal exposure to hyperglycemia acutely produces insulin resistance. As hyperinsulinemia and placental insufficiency have no such impact, this occurs likely via direct tissue effects of hyperglycemia. Furthermore, these findings show that skeletal muscle is uniquely susceptible to immediate and persistent insulin resistance induced by hyperglycemia.

El presente trabajo tiene como objetivo ahondar en los conceptos de “motivación escolar” y “compromiso escolar” en el contexto de los procesos educativos, examina en qué medida las conceptualizaciones que ofrece la bibliografía anglosajona son compatibles o están representadas en la iberoamericana, con miras a precisar con mayor detalle sus diferencias para favorecer futuras investigaciones o intervenciones. Para ello, se llevó a cabo una revisión teórica que pone en discusión los avances en el análisis de ambos conceptos, se descubrieron similitudes y diferencias en las dimensiones constitutivas de cada una. La de origen iberoamericano trata ambos conceptos como homologables entre sí y produce confusiones conceptuales. Esta revisión permite precisar las diferencias, lo que puede ser de utilidad para favorecer futuras investigaciones o intervenciones.

Authors: Alvarado Cordero Silvia Elena , Frías Quesada Carmen María
Published: November 2018

Este artículo presenta los principales hallazgos de la investigación “Factores de riesgo psicosociales en población universitaria”, realizada con estudiantes de la Sede Rodrigo Facio de la Universidad de Costa Rica. Se estudiaron los factores de riesgo: ansiedad, codependencia, baja autoestima y depresión, y se relacionaron con la condición de ser persona adulta cuyos progenitores presentaban abuso de bebidas alcohólicas. La investigación fue planteada en colaboración con personal funcionario de la Universidad de Puerto Rico, Recinto Río Piedras. Esta fue de tipo correlacional y para recopilar la información se aplicó un cuestionario en línea, el cual, en su versión inicial, fue el utilizado en la investigación realizada en Puerto Rico y cuyas variables fueron los factores de riesgo objeto de estudio. Participaron 2009 estudiantes, que de manera voluntaria y en condiciones de anonimato y confidencialidad estuvieron de acuerdo en completar el cuestionario. Los resultados muestran que el grupo de participantes se caracteriza, en su mayoría, con probabilidades de codependencia, síntomas de depresión entre leves y moderados, con ausencia de síntomas de ansiedad y una autoestima normal y alta. No se encontraron diferencias estadísticamente significativas en ninguno de los factores de riesgo estudiados, entre los hijas e hijos de progenitores con abuso de alcohol (HADA) y aquellos progenitores que no lo presentan (NO HADA). El estudio aportó información que puede contribuir en la comprensión de los factores de riesgo de la población universitaria y para proponer acciones que contribuyan a su enfrentamiento desde el quehacer de la profesión de orientación.

La presente investigación tuvo como objetivo descubrir cuáles son los estilos de aprendizaje dominante de estudiantes de primero a cuarto nivel de la carrera de Tecnología en Análisis de Sistemas, semestre académico octubre 2015 – marzo 2016, con el propósito de mejorar su proceso de enseñanza. Para llevar este estudio, se plantearon los siguientes procesos: Elaboración del estado del arte en torno a estilos de aprendizaje para conocer las diversas metodologías y resultados. El modelo utilizado es el propuesto por Felder-Silverman, porque este instrumento se basa en la calidad, confiabilidad y validez, para descubrir el estilo de aprendizaje dominante. Para este estudio se aplicó el proceso de análisis, con sus etapas: Selección del software estadístico, exploración y análisis de datos y preparación de resultados, con el objetivo de identificar grupos homogéneos de un conjunto de estudiantes que se encuestaron, se utiliza la técnica descriptiva, a través de un análisis de clustering. Se usó software libre y de código abierto, Weka, porque permite implementar una variedad de algoritmos. El estilo de aprendizaje dominante de estudiantes de la carrera de Tecnología en Análisis de Sistemas fue: visual (VIS) – intuitivo (INT) - activo (ACT) y secuencial (SEC).
Pluralidad de causas en la demanda por una carrera universitaria, estudio de la zona 3 – Ecuador
Authors: Viteri Robayo Carmen Patricia
Published: November 2018

Existe una pluralidad de causas que confluyen en la toma de decisiones a la hora de elegir una carrera universitaria; de ahí que el objetivo de este artículo sea revisar variables individuales, familiares y sociales como posibles condicionantes para demandar por una educación superior a través de una encuesta semiestructurada. Se trató de un diseño descriptivo, de corte transversal, en la que mediante un muestreo estratificado se analizaron las respuestas de 5660 estudiantes hombres y mujeres de 16 a 19 años, que pertenecen a la zona tres de Ecuador. Se encontró diferencia estadísticamente significativa entre las expectativas de desarrollo profesional; con respecto a género, las mujeres optaron por carreras de ciencias sociales, mientras que los hombres por las ciencias exactas. El nivel de educación de los padres y madres y los ingresos familiares son variables que analizadas al 95% de confianza dieron un nivel altamente significativo frente a la demanda por una educación superior, se observó una tendencia positiva en cada variable. La prueba ji-cuadrado indica que lo que motivó a jóvenes bachilleres a continuar con estudios superiores difiere significativamente con respecto al género; mientras que para mujeres la satisfacción personal y mejores posibilidades de encontrar empleo, es lo que les impulsó a continuar con sus estudios; para los hombres fue la expectativa de ganar más dinero y el estatus social que aporta un título universitario. Se concluyó que los determinantes familiares y sociales son categóricos a la hora de optar por una carrera universitaria, frente a los determinantes individuales.

La presente investigación tiene por objetivo observar el impacto que produce el uso de un software educativo con estrategias didácticas dentro del campo de la aptitud académica concerniente al razonamiento numérico, verbal y abstracto en la educación, considerando la teoría cognitiva del diseño instruccional de Robert Gagné, que propicia el desarrollo de habilidades y destrezas en el aprendizaje. Se trabajó con 175 estudiantes que cursan el último año de educación media de cuatro unidades educativas de la ciudad de Riobamba. Las evaluaciones se llevaron a cabo al iniciar y al finalizar la investigación con pruebas similares a las aplicadas para el ingreso a las universidades. Como resultado de la investigación se observó que 155 estudiantes incrementaron su puntuación luego de la preparación con el software, lo cual representó un crecimiento del 94,12 % en el puntaje obtenido, lo que permite concluir que las tecnologías informáticas son herramientas de apoyo para el desarrollo de aptitudes académicas.
Análisis factorial de correspondencias: Estudio en creencias y estilos de enseñanza en docentes de matemática
Authors: Espeleta Sibaja Annia , Rodríguez Rojas Oldemar
Published: November 2018

Este artículo presenta los resultados de un estudio sobre los estilos de enseñanza y las creencias epistemológicas del profesorado de matemática de educación media, graduado de la Universidad de Costa Rica. Asimismo, dado que la investigación siguió una metodología descriptiva y correlacional, se aplicó un cuestionario de ítems de selección única a 110 docentes de matemática formados en esta universidad, para la recolección de datos (2010-2013). Por otra parte, se analizaron las dimensiones epistemológica y pedagógica vinculadas a los estilos de enseñanza mediante el análisis factorial de correspondencias (AFC), pues este permite encontrar semejanzas en proyecciones de pocas dimensiones de acuerdo con las modalidades de respuesta obtenidas. Finalmente, dichos hallazgos ofrecen un marco de referencia de supuestos relacionados con la matemática, la naturaleza de la disciplina y su enseñanza, los cuales, a su vez, son útiles para analizar las prácticas de aula y la formación de docentes.
La crisis de la educación musical como consecuencia de la decadencia de la institución educativa
Authors: Angel-Alvarado Rolando
Published: November 2018

La institución educativa está en crisis porque diversos elementos ponen en duda principios fundamentales como la equidad y la calidad. Este estudio revisa la cadena de valores que existe en la institución educativa, que abarca desde las agencias supranacionales hasta la escuela, desde la perspectiva de la educación musical. El método se enmarca en el diseño cualitativo, según la teoría fundamentada centrada en el método comparativo constante. Los resultados muestran que la decadencia de la institución educativa se replica en la educación musical y, lo más preocupante, las desigualdades socioeducativas surgen durante el diseño curricular. En conclusión, el enfoque sociomusical hace posible la superación de la crisis, ya que reconoce la complejidad del mundo cultural al promover una interacción sistemática entre la institución educativa y el resto de los grupos sociales en el mundo.
The methodological remainder in news translation research: outlining the background
Authors: Davier Lucile , Schäffner Christina , Van Doorslaer Luc
Published: November 2018

This background paper recalls the main findings gained so far in news translation research. It also presents issues and questions which still deserve scholarly attention. The contributions to this special issue are contextualized in relation to research into news translation, or journalistic translation more widely. One of the major issues concerns the choice of methodological approaches to tackle the phenomenon of news translation. The contributions illustrate scope and limitations of various methodologies, which are mainly product-oriented and advocate for triangulation with participant-centred methods.
