Literary translation and quality assessment analysis – its significance in translation training

This paper aims to highlight the role of translation quality assessment in translation training so as to develop students’ translation competence and skills to face translation problems. An analysis to assess literary translation quality is proposed before proceeding to discuss its pedagogical implementation.

Expectativas sobre la regulación de la independencia del auditor en el processo de fortalecimiento de la auditoría. Implicaciones para España y Portugal

Este trabajo pretende concretar las expectativas sobre el refuerzo de la independencia de los auditores en la Unión Europa como medio escogido para poder abordar los conflictos de intereses inherentes al panorama actual, caracterizado por factores como el nombramiento de los auditores por la empresa auditada, bajos niveles de rotación o la prestación de servicios distintos a la auditoría. En este momento de crisis, la “International Federation of Accountants” (IFAC) reclama a la profesión auditora que desempeñe un papel activo en el desarrollo de organizaciones, mercados financieros y economías estables y sostenibles; por su parte, la Unión Europea considera conveniente seguir debatiendo la función de las auditorías como garante de la veracidad de la solidez financiera de las empresas. Nuestro objetivo es concretar la incidencia de las propuestas de modificación de la Octava Directiva provocará en la normativa interna de España y Portugal. Se definen cambios importantes, sobre todo en el caso de las Entidades consideradas de Interés Público (EIP), en temas como la rotación obligatoria, el fortalecimiento del Comité de Auditoría o la prohibición de la prestación de servicios adicionales. Se concluye que la Comisión Europea se encuentra en un momento histórico en el que debe plantear si modifica o no las reglas de juego de la prestación de servicios de auditoría que busquen reforzar esa imagen del auditor como un servicio de interés público.

MnFe2O4@CNT-N as novel electrochemical nanosensor for determination of caffeine, acetaminophen and ascorbic acid

For the first time, a glassy carbon electrode (GCE) modified with novel N-doped carbon nanotubes (CNT-N) functionalized with MnFe2O4 nanoparticles (MnFe2O4@CNT-N) has been prepared and applied for the electrochemical determination of caffeine (CF), acetaminophen (AC) and ascorbic acid (AA). The electrochemical behaviour of CF, AC and AA on the bare GCE, CNT-N/GCE and MnFe2O4@CNT-N/GCE were carefully investigated using cyclic voltammetry (CV) and square-wave voltammetry (SWV). Compared to bare GCE and CNT-N modified electrode, the MnFe2O4@CNT-N modified electrode can remarkably improve the electrocatalytic activity towards the oxidation of CF, AC and AA with an increase in the anodic peak currents of 52%, 50% and 55%, respectively. Also, the SWV anodic peaks of these molecules could be distinguished from each other at the MnFe2O4@CNT-N modified electrode with enhanced oxidation currents. The linear response ranges for the square wave voltammetric determination of CF, AC and AA were 1.0 × 10−6 to 1.1 × 10−3 mol dm−3, 1.0 × 10−6 to 1.0 × 10−3 mol dm−3 and 2.0 × 10−6 to 1.0 × 10−4 mol dm−3 with detection limit (S/N = 3) of 0.83 × 10−6, 0.83 × 10−6 and 1.8 × 10−6 mol dm−3, respectively. The sensitivity values at the MnFe2O4@CNT-N/GCE for the individual determination of AC, AA and CF and in the presence of the other molecules showed that the quantification of AA and CF show no interferences from the other molecules; however, AA and CF interfered in the determination of AC, with the latter molecule showing the strongest interference. Nevertheless, the obtained results show that MnFe2O4@CNT-N composite material acted as an efficient electrochemical sensor towards the selected biomolecules.

Detrimental role of prolonged sleep deprivation on adult neurogenesis

Adult mammalian brains continuously generate new neurons, a phenomenon called adult neurogenesis. Both environmental stimuli and endogenous factors are important regulators of adult neurogenesis. Sleep has an important role in normal brain physiology and its disturbance causes very stressful conditions, which disrupt normal brain physiology. Recently, an influence of sleep in adult neurogenesis has been established, mainly based on sleep deprivation studies. This review provides an overview on how rhythms and sleep cycles regulate hippocampal and subventricular zone neurogenesis, discussing some potential underlying mechanisms. In addition, our review highlights some interacting points between sleep and adult neurogenesis in brain function, such as learning, memory, and mood states, and provides some insights on the effects of antidepressants and hypnotic drugs on adult neurogenesis.
