Authenticity, Culture and Language Learning

In philosophy, authenticity has been used with two meanings: one entails the notion of correspondence; the other entails the notion of genesis (Cooper, 1983: 15). As in certain branches of philosophy, language teaching has perhaps clung too long to the first of these notions of authenticity at the expense of the other. This paper reviews four key conceptualisations of authenticity which have emerged in the field of applied linguistics: text authenticity, authenticity of language competence, learner authenticity and classroom authenticity. If any of these types of authenticity is couched exclusively in terms of one usage or the other, it can lead to an impoverishment and objectification of the experience of language learning. Text authenticity can lead to a poverty of language; authenticity of competence can lead to a poverty of performance; learner authenticity can lead to a poverty of interpretation; classroom authenticity can lead to a poverty of communication. This paper proposes that a pedagogy of intercultural communication be informed by a more hybrid view of authenticity as a process of subjectification, derived from the Heideggerian concept of self-concern

Listening to the voices of women suffering perinatal psychological distress

This article suggests that transactional analysis can be an effective treatment approach for women suffering from mental health conditions and the emotional and life disturbances that may occur during the perinatal period. It offers a brief introduction to perinatal psychological distress followed by a description of the use of transactional analysis psychotherapy for this condition. The article outlines a new model for a research project that aims to ascertain women’s views on the helpfulness of the treatment and to gain a better understanding of the stigma often associated with perinatal mental health issues. The author argues for the necessity of qualitative research to assess the efficacy of transactional-analysis-based treatment and to increase our knowledge about the change process in transactional analysis psychotherapy with this client population as well as to inform future transactional analysis treatment protocols

Contextualisation and authenticity in TBLT: voices from Chinese classrooms

In view of ongoing debates about the future of TBLT in EFL contexts (Thomas & Reinders, 2015; Zheng & Borg, 2014), we present a detailed case study of teacher beliefs and practices regarding TBLT conducted in a secondary school in mainland China with a long history of communicative and task-based teaching approaches. We used a mixed-methods approach to gather a broad range of triangulated data, combining individual interviews, material analysis and observations coded using a novel task-focused version of the COLT scheme (Littlewood, 2011; Spada & Fröhlich, 1995). Quantitative and qualitative findings revealed positive beliefs about TBLT principles in general, reflecting strong institutional support for communicative teaching. However, there was marked variability between beliefs and practices in using tasks, especially with beginner-level learners. Most teachers demonstrated an intrinsic lack of confidence in using tasks as more than a communicative ‘add-on’ to standard form-focused teaching. We argue this demonstrates a need for building teacher autonomy (Aoki, 2002; Benson, 2007), in implementing TBLT, even in supportive settings, to support successful authentic contextualising TBLT principles in different EFL contexts

Comparative study of deuterium retention and vacancy content of self-ion irradiated tungsten

Self-ion irradiation of pure tungsten with 2 MeV W ions provides a way of simulating microstructures generated by neutron irradiation in tungsten components of a fusion reactor. Transmission electron microscopy (TEM) has been used to characterize defects formed in tungsten samples by ion irradiation. It was found that tungsten irradiated to 0.85 dpa at relatively low temperatures develops a characteristic microstructure dominated by dislocation loops and black dots. The density and size distribution of these defects were estimated. Some of the samples exposed to self-ion irradiation were then implanted with deuterium. Thermal Desorption Spectrometry (TDS) analysis was performed to estimate the deuterium inventory as a function of irradiation damage and deuterium release as a function of temperature. Increase of inventory with increasing irradiation dose followed by slight decrease above 0.1 dpa was found. Application of Positron Annihilation Spectroscopy (PAS) to self-irradiated but not deuterium implanted samples enabled an assessment of the density of irradiation defects as a function of exposure to highenergy ions. The PAS results show that the density of defects saturates at doses in the interval from 0.085 to 0.425 displacements per atom (dpa). These results are discussed in the context of recent theoretical simulations exhibiting the saturation of defect microstructure in the high irradiation exposure limit. The saturation of damage found in PAS agrees with the simulation data described in the paper. (c) 2021 The Authors. Published by Elsevier B.V.

Paradoxical alliances in transactional analysis psychotherapy for anxiety : a systematic adjudicated case study

This article considers the use of the technique of paradoxical alliances in transactional analysis psychotherapy with a 37-year-old white French woman over two sets of sessions. The authors hypothesize that this technique, which has not yet been widely used in TA, can be effective in the treatment of anxiety disorders and offers a useful addition to existing transactional analysis methods. The first set of sessions with the client occurred before the paradoxical alliances approach had been developed, and although therapy had some benefits, it did not result in lasting change for the client. In the second set of sessions, the paradoxical alliances technique was applied and resulted in a deep, lasting improvement in the client’s anxiety attack

Robust impurity detection and tracking for tokamaks

A robust impurity detection and tracking code, able to generate large sets of dust tracks from tokamak camera footage, is presented. This machine learning–based code is tested with cameras from the Joint European Torus, Doublet-III-D, and Magnum-PSI and is able to generate dust tracks with a 65–100% classification accuracy. Moreover, the number dust particles detected from a single camera shot can be up to the order of 1000. Several areas of improvement for the code are highlighted, such as generating more significant training data sets and accounting for selection biases. Although the code is tested with dust in single two-dimensional camera views, it could easily be applied to multiple-camera stereoscopic reconstruction or nondust impurities.</p

Oral Ondansetron Administration in Emergency Departments to Children with Gastroenteritis: An Economic Analysis

Stephen Freedman and colleagues performed a cost analysis of the routine administration of ondansetron in both the United States and Canada and show that its routine administration to eligible children in such settings could provide substantial benefit

Incidence of Respiratory Virus-Associated Pneumonia in Urban Poor Young Children of Dhaka, Bangladesh, 2009–2011

Pneumonia is the leading cause of childhood death in Bangladesh. We conducted a longitudinal study to estimate the incidence of virus-associated pneumonia in children aged <2 years in a low-income urban community in Dhaka, Bangladesh.We followed a cohort of children for two years. We collected nasal washes when children presented with respiratory symptoms. Study physicians diagnosed children with cough and age-specific tachypnea and positive lung findings as pneumonia case-patients. We tested respiratory samples for respiratory syncytial virus (RSV), rhinoviruses, human metapneumovirus (HMPV), influenza viruses, human parainfluenza viruses (HPIV 1, 2, 3), and adenoviruses using real-time reverse transcription polymerase chain reaction assays.Between April 2009-March 2011, we followed 515 children for 730 child-years. We identified a total of 378 pneumonia episodes, 77% of the episodes were associated with a respiratory viral pathogen. The overall incidence of pneumonia associated with a respiratory virus infection was 40/100 child-years. The annual incidence of pneumonia/100 child-years associated with a specific respiratory virus in children aged < 2 years was 12.5 for RSV, 6 for rhinoviruses, 6 for HMPV, 4 for influenza viruses, 3 for HPIV and 2 for adenoviruses.Young children in Dhaka are at high risk of childhood pneumonia and the majority of these episodes are associated with viral pathogens. Developing effective low-cost strategies for prevention are a high priority

One transition, many transitions? A corpus-based study of societal sustainability transition discourses in four civil society’s proposals

When the civil society makes ‘transition’ its label, it cannot be assumed that different civil society actors share compatible varieties of localist or radical transformationists discourses. This study has comparatively analyzed the discourses in four civil society sustainability transition proposals using a corpus-based methodology. We found that the proposals are similar as they identify the economy as an object and an entry point for transition, frame the economy as embedded in the socio–ecological system, ascribe agency to grassroots movements for transitions from the bottom–up. We also found crucial differences among the discourses regarding the role of the State, the degree of reform or radical innovation, the degree of imaginative character of the sustainability vision, the degree of opposition to capitalism. We suggest that insights on how the civil society employs notions of transition with respect to the themes of politics, emotions and place can help advance theorizations and practices of societal sustainability transitions led by the civil society
