About 80% of young people use personal listening devices (PLDs) including MP3 players to listen to music, which consists of sound components with various frequencies. Previous studies showed that exposure to noise of high intensities affected balance in humans. However, there is no information about a frequency-dependent effect of sound components in music from a PLD on balance in young people. In this study, we determined the associations between sound component levels (dB) at 100, 1000 and 4000 Hz in music from a portable listening device (PLD) and balance objectively determined by posturography in young adults (n = 110). We divided the subjects into two groups (low and high exposure groups) based on cut-off values of sound component levels at each frequency using receiver operating characteristic (ROC) curves. Balance in the high exposure group (≥46.6 dB) at 100 Hz was significantly better than that in low exposure group in logistic regression models adjusted for sex, BMI, smoking status and alcohol intake, while there were no significant associations at 1000 and 4000 Hz. Thus, this study demonstrated for the first time that the sound component at 100 Hz with more than 46.6 dB in music improved balance in young adults.

The homeostasis of the proteome depends on the tight regulation of the mRNA and protein abundances, of the translation rates, and of the protein lifetimes. Results from several studies on prokaryotes or eukaryotic cell cultures have suggested that protein homeostasis is connected to, and perhaps regulated by, the protein and the codon sequences. However, this has been little investigated for mammalsin vivo. Moreover, the link between the coding sequences and one critical parameter, the protein lifetime, has remained largely unexplored, bothin vivoandin vitro. We tested this in the mouse brain, and found that the percentages of amino acids and codons in the sequences could predict all of the homeostasis parameters with a precision approaching experimental measurements. A key predictive element was the wobble nucleotide. G-/C-ending codons correlated with higher protein lifetimes, protein abundances, mRNA abundances and translation rates than A-/U-ending codons. Modifying the proportions of G-/C-ending codons could tune these parameters in cell cultures, in a proof-of-principle experiment. We suggest that the coding sequences are strongly linked to protein homeostasisin vivo, albeit it still remains to be determined whether this relation is causal in nature.

Ongoing studies of a multiple track-bearing horizons from massive excavations in the Jinju Formation (Lower Cretaceous) of South Korea have yielded a remarkable diversity of avian, non-avian dinosaur, pterosaur, crocodilian and mammal tracks, many very small and well preserved. Here we report diminutive, didactyl tracks (~1.0 cm long) assigned to a new dromaeosaurid ichnogenus Dromaeosauriformipes, which resembles the larger, but still quite small, ichnogenus Dromaeosauripus, also from the same formation only 30 km away. These diminutive tracks are consistent with the foot size of smaller dromaeosaurid taxa like Early Cretaceous Microraptor from China, and may represent diminutive species or juveniles of larger species. The association of tracks with lakeshore sediments is consistent with the evidence that Microraptor was a fish eater. Two trackways and isolated tracks indicate variable trackmaker gaits and speeds. If oviparous, as assumed for most non-avian dinosaur neonates, the trackmakers must have hatched from tiny eggs. Previous studies of the Korean Cretaceous indicate the presence of other diminutive (~1.0 cm long) theropod tracks (Minisauripus). Such occurrences strongly suggest that small tracks attributed to juveniles, or very small tetrapod species, are more common than previously supposed especially where suitable preservation conditions prevailed.

Published: November 2018

Understanding the mechanisms that support the arrival, establishment and spread of species over an introduced range is crucial in invasion ecology. We analysed the unintentionally introduced herbaceous species that are naturalised in the five Mediterranean-climate regions. There is an asymmetry in the species flows among regions, being the Iberian Peninsula the main donor to the other regions. At interregional scale, the species’ capacity to spread among regions is related to the ecological versatility of the species in the donor area (Iberian Peninsula). At intraregional scale, the species’ capacity to successfully occupy a complete region first depends on the time elapsed from its introduction and afterwards on the degree of occurrence in the region of origin, which is commonly related to its chance of coming into contact with humans. Information on exotic species in their origin region provides insights into invasion process and decision-making to reduce the risks of future invasions.

Viticulture is of high socio-economic importance; however, its prevalent practices severely impact the environment and human health, and criticisms from society are raising. Vine managements systems are further challenged by climatic changes. Of the 8 million hectares grown worldwide, conventional and organic practices cover 90% and 9% of acreage, respectively. Biodynamic cultivation accounts for 1%. Although economic success combined with low environmental impact is widely claimed by biodynamic winegrowers from California, to South Africa, and France, this practice is still controversial in viticulture and scientific communities. To rethink the situation, we encouraged stakeholders to confront conventional and biodynamic paradigms in a Participative-Action-Research. Co-designed questions were followed up by holistic comparison of conventional and biodynamic vineyard managements. Here we show that the amplitude of plant responses to climatic threats was higher in biodynamic than conventional management. The same stood true for seasonal trends and pathogens attacks. This was associated with higher expression of silencing and immunity genes, and higher anti-oxidative and anti-fungal secondary metabolite levels. This suggests that sustainability of biodynamic practices probably relies on fine molecular regulations. Such knowledge should contribute to resolving disagreements between stakeholders and help designing the awaited sustainable viticulture at large.

Published: November 2018

Idiopathic pulmonary fibrosis (IPF) is a devastating and common chronic lung disease pathologically characterized by loss of epithelial cells and activation of fibroblasts and myofibroblasts. The etiology of IPF remains unclear and the disease pathology is poorly understood with no known efficacious therapy. PM014 is an herbal extract that has been shown to have beneficial effects in pulmonary diseases, which are likely to exert anti-inflammatory bioactions. In the present study, we observed that bleomycin (BLM) caused increased inflammatory infiltration as well as collagen deposition in lungs of mice on day 14 after treatment. Administration of PM014 suppressed BLM-induced inflammatory responses and fibrotic changes in dose-dependent manner in mice. Additionally, we provided in vitro evidence suggesting that PM014 inhibited TGF-β1-induced epithelial-mesenchymal transition (EMT) and fibroblast activation in alveolar epithelial cells and human lung fibroblasts from healthy donor and IPF patients. PM014 appeared to target TGF-β1 signaling via Smad-dependent pathways and p38 mitogen-activated protein kinases (MAPKs) pathways. Taken together, our data suggest that PM014 administration exerts a protective effect against lung fibrosis and highlight PM014 as a viable treatment option that may bring benefits to patient with IPF.

Published: November 2018

Transient hepatic steatosis upon liver resection supposes functional relationships between lipid metabolism and liver regeneration. Repin1 has been suggested as candidate gene for obesity and dyslipidemia by regulating key genes of lipid metabolism and lipid storage. Herein, we characterized the regenerative potential of mice with a hepatic deletion of Repin1 (LRep1−/−) after partial hepatectomy (PH) in order to determine the functional significance of Repin1 in liver regeneration. Lipid dynamics and the regenerative response were analyzed at various time points after PH. Hepatic Repin1 deficiency causes a significantly decreased transient hepatic lipid accumulation. Defects in lipid uptake, as analyzed by decreased expression of the fatty acid transporter Cd36 and Fatp5, may contribute to attenuated and shifted lipid accumulation, accompanied by altered extent and chronological sequence of liver cell proliferation in LRep1−/− mice. In vitro steatosis experiments with primary hepatocytes also revealed attenuated lipid accumulation and occurrence of smaller lipid droplets in Repin1-deficient cells, while no direct effect on proliferation in HepG2 cells was observed. Based on these results, we propose that hepatocellular Repin1 might be of functional significance for early accumulation of lipids in hepatocytes after PH, facilitating efficient progression of liver regeneration.

Published: November 2018

Breast microbiota compositions are not well understood, and a few recent reports have begun to explore the correlation between breast tissue dysbiosis and cancer. Given that various methods for breast microbiota detection were used, the aim of the present paper was to clarify which hypervariable region of the 16S-rRNA gene (V2, V3, V4, V6 + 7, V8, and V9) is the most informative for breast tissue microbiota. Core needle biopsies (CNBs) were compared with surgical excision biopsies (SEBs) to find a less invasive form of recovery useful for the analysis of a larger statistical population and potentially for diagnostic use of breast tissue microbiota. Finally, this study was the first to analyse the breast microbiota of tumours and paired normal tissues of a Mediterranean population. Our findings showed that the V3 region is the most informative for breast tissue microbiota, accounting for 45% of all reads. No significant differences were found between CNB and SEB specimens in terms of total reads and numbers of Operational Taxonomic Units (OTUs). Moreover, we find that more similarities than differences exist between tumours and adjacent normal tissues. Finally, the presence of the Ralstonia genus is associated with breast tissue.

Published: November 2018

We have recently reported that green soybean cultivar, echigomidori, and not the yellow cultivar, fukuyutaka, is a rich source of hormone-like peptide leginsulin consisting of 37 amino acids (Leg_1_37, PDB 1JU8A) and its C-terminal glycine deletant, Leg_1_36. Green soybean is mature, but the color of the seedcoat and cotyledon remains green. Therefore, in this study, we examined the leginsulin content in different varieties of 11 colored soybeans (including green, yellow, red, brown and black) and edamame (immature soybean). Profile analysis of soybean constituents by LC-MS showed that Leg_1 (36 + 37) detected as a prominent peak in 3 green and 1 yellow soybean cultivar was the strongest contributor in principal component analysis, indicating Leg_1 is the most characteristic feature for distinguishing soybean cultivars. However, smaller amounts of leginsulin-like peptides, defined as Leg_2 and Leg_3, were detected in other samples. The cDNA sequences and LC-MS/MS analyses revealed that Leg_2 was a homologue of Leg_1 with three amino acid substitutions derived from SNPs, while Leg_3 was a Leg_1/Leg_2 paralog. Expression levels of Leg_1 were markedly higher than Leg_2 and Leg_3. Additionally, in glucose uptake assay, purified TRX-His-tag fused recombinant Leg_1_37 prepared by bacterial expression showed stronger insulin-like activities than other variants including Leg_2, Leg_3, and their Gly deletants in myotube-like differentiated L6 and C2C12 cells. These results suggest that dietary consumption of soybean seed, especially including a higher amount of Leg_1_37, could be useful for lowering of blood glucose.

Published: November 2018

Avian influenza remains an important zoonotic disease with a significant global impact. The spread of H5 highly pathogenic avian influenza (HPAI) viruses (clade 2.3.4.4) by migratory birds has caused outbreaks in wide geographic regions (Asia, Europe, and North America) with great economic losses during 2014–2015. Efficient vaccines and vaccination approaches are needed to enhance protective immunity against HPAI viruses. Although several vaccination strategies have been developed, none has been satisfactory. Our strategy has been to use avirulent vaccine strain of Newcastle disease virus (NDV) as a vaccine vector for HPAI viruses. For poultry vaccination, we previously generated a new platform of chimeric NDV vector to overcome preexisting maternal antibodies to NDV in poultry. In this study, we have generated vaccine candidates targeting H5 clade 2.3.4.4 HPAI viruses by using our chimeric NDV and conventional NDV strain LaSota vectors for a heterologous prime-boost immunization approach. Co-expression of the HA and NA proteins by our vaccine vectors induced enhanced HPAI virus specific immune responses in specific-pathogen free and broiler chickens prior to challenge. Further, these vaccine candidates efficiently protected broiler chickens from mortality, clinical signs, and shedding of homologous and heterologous H5 HPAI viruses and highly virulent NDV, thus providing a dual vaccination approach in the field.

Published: November 2018

The incidence and prevalence of neuroendocrine tumors (NETs) are continually increasing. While it is known that NET symptoms often predate diagnosis, their prevalence and impact on resource utilization and costs are largely unknown. We identified 9,319 elderly patients diagnosed with NETs between 1/2003 and 12/2011 from the Surveillance, Epidemiology and End Results (SEER)-Medicare. We examined the patients’ conditions potentially associated with NET, resource utilization and costs during the year before diagnosis. We found that NET patients were more likely to have diagnoses of hypertension (63.8% vs. 53.3%), abdominal pain (22.2% vs. 7.6%), heart failure (11.7% vs. 8.0%), diarrhea (5.8% vs. 1.8%), peripheral edema (5.4% vs. 3.8%) and irritable bowel syndrome (1.2% vs. 0.5%) compared to the non-cancer control group. They also had much higher resource utilization including number of outpatient visits (mean: 22.1 vs. 17.2), percentage with ER visits (20.9% vs. 11.6%), and hospitalizations (28.4% vs. 17.0%). Similarly, NET patients incurred significantly higher total (mean: $14602 vs. $9464), outpatient (mean: $5987 vs. $4253), and inpatient costs (mean: $8615 vs. $5211). This first population-based study on the pre-diagnosis symptoms and healthcare utilization found that NET patients were more likely to have certain conditions and incur higher resource utilizations and costs.

Published: November 2018

The roles of autophagy-related proteins as diagnostic or monitoring biomarkers in Parkinson’s disease (PD) have not been clearly elucidated. We recruited 32 patients with early-stage PD and 28 control subjects, and evaluated parkinsonian motor symptoms and dopamine transporter imaging data. Cerebrospinal fluid (CSF) levels of LC3B, Beclin1, and LAMP-2 were estimated using ELISAs, and CSF levels of ATG5, ATG7, and p62 were examined by immunoblotting. Additionally, we also assessed the levels of α-synuclein, total tau, and phosphorylated tau in CSF using ELISAs. Significant differences in the levels of LC3B, LAMP-2, and Beclin1 were observed between the PD and control groups. Using 29.8 pg/mL as the cut-off value for a diagnostic biomarker of PD, CSF LC3B levels exhibited high sensitivity (96.9%) and specificity (89.3%) with an area under the curve of 0.982. Furthermore, LC3B was significantly correlated with the asymmetry index in the caudate and putamen, as estimated by a semi-quantitative analysis of [18F] N-(3-fluoropropyl)-2β-carbon ethoxy-3β-(4-iodophenyl) nortropane (FP-CIT) positron emission tomography (PET). CSF levels of LC3B represented a potential diagnostic and prognostic biomarker of early-stage PD in patients. Based on our findings, molecular biological changes in PD are associated with dysregulation of the lysosomal autophagy pathway.

Dectin-2 is a C-type lectin involved in the recognition of several pathogens such as Aspergillus fumigatus, Candida albicans, Schistosoma mansonii, and Mycobacterium tuberculosis that triggers Th17 immune responses. Identifying pathogen ligands and understanding the molecular basis of their recognition is one of the current challenges. Purified M. tuberculosis mannose-capped lipoarabinomannan (ManLAM) was shown to induce signaling via Dectin-2, an activity that requires the (α1 → 2)-linked mannosides forming the caps. Here, using isogenic M. tuberculosis mutant strains, we demonstrate that ManLAM is a bona fide and actually the sole ligand mediating bacilli recognition by Dectin-2, although M. tuberculosis produces a variety of cell envelope mannoconjugates, such as phosphatidyl-myo-inositol hexamannosides, lipomannan or manno(lipo)proteins, that bear (α1 → 2)-linked mannosides. In addition, we found that Dectin-2 can recognize lipoglycans from other bacterial species, such as Saccharotrix aerocolonigenes or the human opportunistic pathogen Tsukamurella paurometabola, suggesting that lipoglycans are prototypical Dectin-2 ligands. Finally, from a structure/function relationship perspective, we show, using lipoglycan variants and synthetic mannodendrimers, that dimannoside caps and multivalent interaction are required for ligand binding to and signaling via Dectin-2. Better understanding of the molecular basis of ligand recognition by Dectin-2 will pave the way for the rational design of potent adjuvants targeting this receptor.
RanBP2 regulates the anti-retroviral activity of TRIM5α by SUMOylation at a predicted phosphorylated SUMOylation motif

Published: November 2018

TRIM5α is a cytoplasmic restriction factor that blocks post-entry retroviral infection. Evidence suggests that its antiviral activity can be regulated by SUMO, but how this is achieved remains unknown. Here, we show that TRIM5α forms a complex with RanGAP1, Ubc9, and RanBP2 at the nuclear pore, and that RanBP2 E3 SUMO ligase promotes the SUMOylation of endogenous TRIM5α in the cytoplasm. Loss of RanBP2 blocked SUMOylation of TRIM5α, altered its localization in primary cells, and suppressed the antiviral activity of both rhesus and human orthologs. In cells, human TRIM5α is modified on K84 within a predicted phosphorylated SUMOylation motif (pSUM) and not on K10 as found in vitro. Non-modified TRIM5α lacked antiviral activity, indicating that only SUMOylated TRIM5α acts as a restriction factor. This work illustrates the importance of the nuclear pore in intrinsic antiviral immunity, acting as a hub where virus, SUMO machinery, and restriction factors can meet.

Published: November 2018

Metal sulfide materials serve as environment-friendly, sustainable, and effective electrode materials for green-energy storage systems. However, their capacity-fading issues related to low electrical conductivity and drastic volume changes during electrochemical cycling have generally limited their application to sodium ion batteries. Here we show that with the combination of an ether-based NaPF6/diglyme electrolyte, the dandelion-shaped manganese sulfide electrode displays enhanced reversible capacity, cycle life, and rate capability. The capacity of 340 mAh g−1 is maintained over more than 1000 cycles at a current density of 5.0 A g−1. Furthermore, discharge capacities of 277 and 230 mAh g−1 at 10 and 20 A g−1 current densities, respectively, are obtained. Our work demonstrates the formation of a protective solid electrolyte interface layer along the surface of the primary seed particle that limits polysulfide dissolution and hence the preservation of the active material during reaction with sodium.

Objectif : La présente étude vise à établir les bénéfi ces d’un entraînement auditif dans le bruit chez des enfants présentant un trouble
du traitement auditif (TTA) et un trouble spécifi que du langage écrit.

Méthodologie : Quatre enfants présentant un TTA et une dyslexie ont participé à cette étude. Une première période de cinq semaines
sans entraînement a été respectée. Puis chaque enfant a effectué un entraînement auditif à l’écoute dans le bruit durant cinq semaines,
à raison d’au moins deux heures par semaine en séances de vingt minutes minimum. Les enfants ont été amenés à discriminer puis à
identifi er des mots mais aussi des phrases et des textes dans un bruit de fond variable en fonction de leurs progrès. Une mesure des
potentiels évoqués auditifs de latence longue, de l’écoute de mots dans le bruit, de l’écoute dichotique de chiffres et de la conscience
phonologique a été réalisée à trois moments : avant la période sans entraînement puis avant et après l’entraînement afi n d’identifi er
les effets de celui-ci. Les parents et les enfants ont rempli un questionnaire relatif à l’écoute en classe à ces trois moments.

Résultats : Les résultats mettent en évidence une évolution dans plusieurs domaines. Tout d’abord, les réponses au questionnaire suggèrent
une amélioration de l’écoute dans des situations d’écoute défavorables. Ensuite, l’observation des données témoigne d’une amélioration de
l’identifi cation des mots dans le bruit pour l’oreille droite, une augmentation de la capacité d’écoute dichotique pour l’oreille gauche et de
meilleurs résultats en conscience phonologique. Enfi n, les mesures électrophysiologiques révèlent une diminution de la latence de l’onde P1.
Das Schädel-Hirn-Trauma im Säuglings- und Kindesalter
Authors: Brentrup Angela , Schipmann Stephanie
Published: November 2018

Das Schädel-Hirn-Trauma (SHT) stellt ein signifikantes medizinisches, soziales und ökonomisches Problem dar und gilt als der häufigste Grund für Behinderungen und Todesfälle im Kindes- und Jugendalter. Die Verletzungsursachen hängen bei Kindern deutlich von der Altersgruppe ab. Unterschieden wird zwischen leichtem, mittelschwerem und schwerem SHT. Die Behandlung eines schweren SHTs sollte stets in Zentren erfolgen und durch die Neurochirurgie begleitet werden. Die Wahl der bildgebenden Diagnostik richtet sich nach Alter, Traumamechanismus und klinischem Befund, in der Regel bleibt in der Primärdiagnostik das CT die Methode der Wahl bei schwerem SHT. Der Schweregrad des SHTs und der klinische Status des Kindes beeinflussen die weitere Therapie (operativ/konservativ). Nach der akuten Phase der Behandlung des SHTs sollte sich eine neurologische Rehabilitationsmaßnahme anschließen, ausdrücklich bei fortbestehenden körperlichen oder geistlichen Funktionseinschränkungen. Zu beachten ist jedoch, dass neuropsychologische Störungen sich auch noch häufig bis zu 2 Jahren posttraumatisch manifestieren können.

A Total Knee Arthroplasty Is Stiffer When the Intraoperative Tibial Force Is Greater than the Native Knee
Authors: Shelton Trevor J. , Howell Stephen M. , Hull Maury L.
Published: November 2018

We hypothesized that a total knee arthroplasty (TKA) with an intraoperative tibial force greater than the tibial force of the native knee has signs of stiffness as measured by loss of extension and flexion, and anterior translation of the tibia. Intraoperative forces in the medial and lateral tibial compartments were measured during passive motion in 71 patients treated with calipered kinematically aligned TKA. Maximum extension, flexion, and the anterior–posterior position of the tibia with respect to the distal femur at 90 degrees of flexion were measured. Measurements were repeated after exchanging to a 2 mm thicker insert. The sum of the average of the medial and lateral compartment forces at 0, 45, and 90 degrees of flexion represented the tibial force through a 90-degree motion arc. For the implanted insert, the tibial force averaged 28 ± 17 lb, which is comparable to the 20 ± 7 lb reported for the native knee. At 6 months, patients reported an average 40 point Oxford Knee and 15 point Western Ontario and McMaster Universities Osteoarthritis (WOMAC) score. For the 2 mm thicker insert, the tibial force averaged 50 ± 28 lb. A 30 lb tibial force greater than native generated a 3-degree loss of extension, a 3-degree loss of flexion, and 3-mm anterior translation of the tibia. Because a TKA with a tibial force greater than native has signs of stiffness, a strategy for lowering this risk is to match the tibial force of the native knee when balancing a TKA as this restored high function.
Deactivation of gyroscopic inertial forces
Authors: Usubamatov R.
Published: November 2018

An inertial gyroscope in engineering manifests several unexplainable properties which physical nature is still unknown in classical mechanics. The new study demonstrates that the origin of the gyroscopic effects is more complex than presented in known publications. The gyroscopic effects manifest the inertial resistance and precession torques acting around different axes. The first torque is generated by the centrifugal and Coriolis forces and the second one by the common inertial forces and the change in the angular momentum. Blocking of the gyroscope motion around one axis deactivates the resistance torques but the precession torques are acting and the gyroscope turns under the action only of the gravity force. These phenomena are the manifestation of the unknown property of a physical matter that represents the new challenge for the researchers of classical mechanics. Newton’s laws are justified for the simple action, but for complex one should be formulated, validated and written new physical laws. For the example, the rotation of the mass around two axes demonstrates the disappearance of the inertial forces that contradicts the principles of physics. This work presents the mathematical model and practical validation of the deactivation of the inertial forces for the spinning rotor around two axes.
Controllable Leidenfrost glider on a shallow water layer
Authors: Sugioka Hideyuki , Segawa Satoru
Published: November 2018

Levitation and self-propelled functions of the Leidenfrost phenomena are attractive. In this study, we propose a Leidenfrost glider having a ratchet-like topology under its body along with the driving method using the asymmetrical viscous vapor flow, as a prototype of a future vehicle that can move on a flat shallow layer freely. We observed that this vehicle can be accelerated to the velocity of approximately 0.2 m/s on a shallow water layer and the direction can be quickly controlled by changing the center of gravity of the vehicle. Our device might be important to reduce the worldwide energy loss of vehicles or to develop innovative microfluidic transportation systems in the future.
Tablet interpreting
Authors: Goldsmith Joshua
Published: November 2018

This pilot study examines the recent phenomenon of tablet interpreting. Based on in-depth interviews with six practitioners, which were transcribed and analyzed inductively, the article presents an overview of software, tools, and technology that interpreters currently utilize in their work. Qualitative and quantitative results demonstrate regular, effective tablet use in various consecutive interpreting settings. Participants feel that these tools meet their needs and outstrip the functionalities offered by pen and paper in most contexts. This study compiles best practices for tablet interpreting, discusses their benefits and challenges, and describes features to consider when assessing new and existing tablets, applications, and styluses. The data underscore the need for training in this budding field, which represents a key area for future research and professional practice.
Interpreter traits and the relationship with technology and visibility
Authors: Mellinger Christopher D. , Hanson Thomas A.
Published: November 2018

Research on technology and interpreting regularly investigates technology-mediated interpreting settings and contrasts various interpreting configurations to better understand how technology changes the interpreting task. This scholarship generally does not account for various personality or character attributes exhibited by interpreters, nor does it examine the actual adoption and usage of these tools. This article presents findings from a survey-based study that examines several interpreter-specific constructs, namely their self-perception of the interpreter’s role and communication apprehension, in conjunction with attitudes toward technology use and adoption. Findings suggest that community interpreters differ from their conference interpreting counterparts and that domain-specific differences emerge between medical and court interpreters with respect to their perceived role and their propensity to adopt new technologies.
Video-mediated interpreting in legal settings in England
Authors: Braun Sabine
Published: November 2018

The increasing use of videoconferencing technology in legal proceedings has led to different configurations of video-mediated interpreting (VMI). Few studies have explored interpreter perceptions of VMI, each focusing on one country, configuration (e.g., interpreter-assisted video links between courts and remote participants) and setting (e.g., immigration). The present study is the first that draws on multiple data sets, countries, settings and configurations to investigate interpreter perceptions of VMI. It compares perceptions in England with other countries, covering common configurations (e.g., court-prison video links, links to remote interpreters) and settings (e.g., police, court, immigration), and considers the sociopolitical context in which VMI has emerged. The aim is to gain systematic insights into factors shaping the interpreters’ perceptions as a step toward improving VMI.
Students’ views on the use of film-basedLangPerformcomputer simulations for dialogue interpreting
Authors: Viljanmaa Anu
Published: November 2018

This article describes the results of the pilot testing phase of the firstLangPerformdialogue interpreting simulations, which replicated authentic communication situations in a Finnish daycare center and consisted of interpreting and sight translation tasks. Five students with German and three with English as their B-language participated in the pilot testing. Afterwards, they were interviewed about their experience and thoughts about the simulations. They were positively surprised by the authenticity of the simulation and regarded the simulation as an excellent additional training method for self-training and self-evaluation. Negative feedback that drew away from authenticity mainly concerned the predetermined time reserved for interpreting, which resulted in there sometimes being long pauses or, on several occasions, not enough time to interpret.
Moses, time, and crisis translation
Authors: Federici Federico M. , Al Sharou Khetam
Published: November 2018

Training translators to react to sudden emergencies is a challenge. This article presents the results of a training experiment
testing the speed of acquisition of the skills necessary to operate the open-source Moses statistical machine translation (SMT)
system. A task-based approach was used with trainee translators who had no experience working with MT technology. The experiment
is a feasibility study to ascertain whether training on Moses SMT could be considered for long-lasting crisis scenarios. The
article reports its findings in four sections. The first section discusses the research context in which ‘crisis translation’ is
defined; the second section illustrates the rationale of the experiment; the third section looks at the results of the training
experiment; and the fourth at the trainees’ perceptions of their learning processes. The conclusion reflects on the viability of
using Moses and on the next phases needed to refine the findings of this first experiment.
