Diversité des pratiques dans la production plurilingue de textes politiques. Comparaison entre trois partis suisses
Authors: Bohn Véronique 
Published: August 2018

Qu’ils soient étatiques ou non, les acteurs qui évoluent dans un système officiellement plurilingue doivent tenir compte de l’existence de plusieurs communautés linguistiques. La question qui se pose alors est de savoir comment il est possible de communiquer politiquement dans un tel contexte. En particulier, il paraît essentiel pour l’existence d’une vie démocratique d’empêcher que les discussions ne soient cloisonnées par publics de langues maternelles différentes et donc d’assurer une coordination des messages entre les langues. Dans notre étude qualitative, nous nous intéressons aux dispositifs que trois partis politiques suisses ont mis en place pour assurer ce lien dans la production des périodiques destinés à leurs membres. Ces pratiques, que nous appelons « modes de coordination interlinguistique », peuvent impliquer, à des degrés divers, l’utilisation de la traduction. Au-delà de la description de ces modes, il s’agit de comprendre les logiques qui guident le choix d’une pratique particulière et qui sont définies comme l’ensemble cohérent d’éléments représentationnels et matériels, internes et externes au parti. Pour comprendre ces logiques, des entretiens semi-structurés ont été menés avec les responsables des publications, et les logiques qu’ils permettent de mettre en évidence ont ensuite été comparées. En particulier, l’accent est mis sur les éléments qui divergent d’un parti à l’autre et qui semblent expliquer l’adoption d’une pratique plutôt qu’une autre. Les résultats sont exposés selon trois grands thèmes : développement historique des publications, perception de la traduction et articulation entre stratégie politique et système de valeurs. De manière plus générale, l’étude suggère que de nombreux éléments entrent en ligne de compte dans la production plurilingue des textes politiques et que la situation est bien plus complexe qu’une simple distinction entre traduction et non-traduction.

Oral squamous cell carcinoma (OSCC) is a major malignant cancer of the head and neck. Long non-coding RNAs (lncRNAs) have emerged as critical regulators during the development and progression of cancers. This study aimed to identify a lncRNA-related signature with prognostic value for evaluating survival outcomes and to explore the underlying molecular mechanisms of OSCC. Associations between overall survival (OS), disease-free survival (DFS) and candidate lncRNAs were evaluated by Kaplan–Meier survival analysis and univariate and multivariate Cox proportional hazards regression analyses. The robustness of the prognostic significance was shown via the Gene Expression Omnibus (GEO) database. A total of 2,493 lncRNAs were differentially expressed between OSCC and control samples (fold change >2, p < 0.05). We used Kaplan–Meier survival analysis to identify 21 lncRNAs for which the expression levels were associated with OS and DFS of OSCC patients (p < 0.05) and found that down-expression of lncRNA AC012456.4 especially contributed to poor DFS (p = 0.00828) and OS (p = 0.00987). Furthermore, decreased expression of AC012456.4 was identified as an independent prognostic risk factor through multivariate Cox proportional hazards regression analyses (DFS: p = 0.004, hazard ratio (HR) = 0.600, 95% confidence interval(CI) [0.423–0.851]; OS: p = 0.002, HR = 0.672, 95% CI [0.523–0.863). Gene Set Enrichment Analysis (GSEA) indicated that lncRNA AC012456.4 were significantly enriched in critical biological functions and pathways and was correlated with tumorigenesis, such as regulation of cell activation, and the JAK-STAT and MAPK signal pathway. Overall, these findings were the first to evidence that AC012456.4 may be an important novel molecular target with great clinical value as a diagnostic, therapeutic and prognostic biomarker for OSCC patients.

AbstractDevelopment of electrocatalysts for hydrogen evolution reaction (HER) with low overpotential and robust stability remains as one of the most serious challenges for energy conversion. Herein, a serviceable and highly active HER electrocatalyst with multilevel porous structure (Co‐Co2P nanoparticles@N, P doped carbon/reduced graphene oxides (Co‐Co2P@NPC/rGO)) is synthesized by Saccharomycete cells as template to adsorb metal ions and graphene nanosheets as separating agent to prevent aggregation, which is composed of Co‐Co2P nanoparticles with size of ≈104.7 nm embedded into carbonized Saccharomycete cells. The Saccharomycete cells provide not only carbon source to produce carbon shells, but also phosphorus source to prepare metal phosphides. In order to realize the practicability and permanent stability, the binderless and 3D electrodes composed of obtained Co‐Co2P@NPC/rGO powder are constructed, which possess a low overpotential of 61.5 mV (achieve 10 mA cm−2) and the high current density with extraordinary catalytic stability (1000 mA cm−2 for 20 h) in 0.5 m H2SO4. The preparation process is appropriate for synthesizing various metal or metal phosphide@carbon electrocatalysts. This work may provide a biological template method for rational design and fabrication of various metals or metal compounds@carbon 3D electrodes with promising applications in energy conversion and storage.

AbstractIn this paper, the utilization of plasmon‐induced cleavage of CI bond in the structure of iodonium salt followed by grafting of organic radicals to Au surface is proposed. The plasmon is excited by the coupling of Au‐covered optical fiber with the laser light source, with wavelength corresponding to the plasmon absorption band, and immersion of fiber in the solution of iodonium salt. Grafting procedure is monitored through the shift of surface plasmon resonanse (SPR) position during the laser light transmission. Further verifications are performed using the surface enhanced Raman spectroscopy (SERS) and scanning electron microscopy and energy‐dispersive X‐ray spectroscopy methods. Only in the case of coincidence of coupled laser emission and initial SPR absorption band wavelengths efficient activation of diaryliodonium salt (IS) is observed. With the aim to introduce hydrophobic and repellent surface properties the di‐[3,5‐bis(trifluoromethyl)phenyl]iodonium tetrafluoroborate salt is used. Surface functionality is further tested using the wettability and antifouling test. Proposed method for the first time utilizes the plasmonic phenomenon as an effective tool for initiating the iodonium salt heterophase reaction and can be considered as extremely effective approach in the case of surface activation, in terms of energy and materials harvesting.

Published: August 2018

AbstractAlthough diversified biological structures have evolved fog collection abilities, the typical speeds of the condensed water droplets on these surfaces are too slow to have practical utility. The main challenge focuses on the elimination of the interfacial hydrodynamic resistance without external energy support. Here, an unusual strategy for superfast self‐support transfer condensed droplets is supported by sliding on seta of desert scorpion. It can be rapidly wetted by the fog droplets owing to its conical shape with linear gradient channels. A loss of interfacial resistance by this hydrodynamically lubricating water membrane could significantly accelerate the movement of the droplets, thus making its velocity increasing by one order of magnitude, or even more. Inspired by this novel strategy, the novel bioinspired materials are fabricated with the similar gradient channel structures and droplet transportation mode, which can make the condensed droplets spontaneously slide on the low‐friction liquid membrane. The fundamental understanding of superfast fog capture and the sliding dynamics of condensed droplets in this system could inspire to develop novel materials or various systems to transfer liquid fast and efficiently without external energy support.

Published: August 2018

Abstract2D monolayer cell cultures are routinely utilized for preclinical cancer drug screening, but the results often do not translate well when drugs are tested in vivo. To address this limitation, a biocompatible chitosan‐PEG‐genipin hydrogel (CSPG gel) is synthesized to create a gel that can be easily dispensed into 96‐well plates at room temperature and neutral pH. The stiffness of this gel is tailored to be within the range of human glioblastoma tissue to promote the formation of tumor spheroids. Differences in cell morphology, proliferation rate, and dose‐dependent drug cytotoxicity are compared among cell spheroids grown on CSPG gels, cells in monolayer culture on tissue culture polystyrene, and cells cultured on Matrigel. Tumor spheroids on CSPG gels display statistically significantly greater resistance to chemotherapeutics than in the conditions where cells do not form spheroids. Gene expression analysis suggests that resistance of cells on CSPG gels to the therapy may be partially attributed to upregulation of ATP‐binding cassette transporters and downregulation of DNA mismatch repair genes stimulated by spheroid formation. These findings suggest CSPG gel generates tumor spheroids that better reflect the malignant behavior of glioblastomas and provides a cost‐effective substrate for preclinical, high‐throughput screening of potential cancer therapeutics.
Perovskite Membranes with Vertically Aligned Microchannels for All‐Solid‐State Lithium Batteries

Published: August 2018

AbstractPerovskite‐type solid‐state electrolytes exhibit great potential for the development of all‐solid‐state lithium batteries due to their high Li‐ion conductivity (approaching 10−3 S cm−1), wide potential window, and excellent thermal/chemical stability. However, the large solid–solid interfacial resistance between perovskite electrolytes and electrode materials is still a great challenge that hinders the development of high‐performance all‐solid‐state lithium batteries. In this work, a perovskite‐type Li0.34La0.51TiO3 (LLTO) membrane with vertically aligned microchannels is constructed by a phase‐inversion method. The 3D vertically aligned microchannel framework membrane enables more effective Li‐ion transport between the cathode and solid‐state electrolyte than a planar LLTO membrane. A significant decrease in the perovskite/cathode interfacial resistance, from 853 to 133 Ω cm2, is observed. It is also demonstrated that full cells utilizing LLTO with vertically aligned microchannels as the electrolyte exhibit a high specific capacity and improved rate performance.
The role of compensation in explaining harmful effects of overtime work on self‐reported heart disease: Preliminary evidence from a Germany prospective cohort study
Authors: Li Jian , Siegrist Johannes 
Published: August 2018

BackgroundResearch evidence suggests harmful effects of overtime work on risk of heart disease. However, whether withdrawing compensation for overtime work (time‐off or money) provides a relevant explanation of this association has not been explored.MethodsUsing cohort data, we included 6345 employees from Germany (3079 men and 3266 women), and applied Poisson regression analysis to examine the prospective association of overtime work without compensation with risk of self‐reported incident heart disease over 2 years.ResultsUncompensated overtime work was associated with an elevated risk of heart disease after adjustment for relevant variables (RR = 1.85, 95%CI: 1.05‐3.25), compared to no overtime work. Stratified analyses indicated particularly strong effects among women and among employees with low socioeconomic position.ConclusionsIn line with the stress‐theoretical model of effort‐reward imbalance at work, these findings document an important role of compensation on heart disease in the frame of overtime work.

Published: August 2018

AimCesarean scar pregnancy (CSP) is a rare type of ectopic pregnancy. The gestational sac is implanted in the myometrium at the site of a previous cesarean section. Mothers with CSP are faced with risks of unpredictable massive bleeding or more fatal complications. The purpose of this retrospective study was to assess the feasibility, efficacy, and reliability of the intraoperative ultrasound‐guided vacuum aspiration method as an effective treatment option for CSP.MethodsWe undertook a retrospective analysis of CSP patients who had undergone the vacuum aspiration method, by reviewing patient records from the period October 2015 to January 2018. All of the operations were carried out under general anesthesia, with patients in the lithotomy position, using suprapubic ultrasonography guidance. A vacuum aspirator was used to aspirate the whole pregnancy material without perforating the previous cesarean section scar.ResultsTen women with CSP were managed successfully by ultrasound‐guided vacuum extraction without complications or further interventions, such as reoperation or methotrexate administration. Three of the 10 patients needed uterine Foley catheter tampon (50 cc) for 4 h after vacuum extraction alone was applied. During the study period, two additional patients who did not meet the criteria for the vacuum extraction method alone were managed with methotrexate plus vacuum application. Because of the rarity of the condition, the majority of CSPs are case reports or small case series reported in published works, with no consensus on the preferred course of treatment.ConclusionThe vacuum extraction method seems to be a good and practical way of treating CSP. Comparisons of efficacy should be undertaken but large sample sizes are required. We hope this study brings a new perspective for larger sample‐sized studies, considering the technique is feasible and applicable.
Alkali Lithosilicates: Renaissance of a Reputable Substance Class with Surprising Luminescence Properties
Authors: Dutzler Daniel , Seibald Markus , Baumann Dominik , Huppertz Hubert 
Published: August 2018

AbstractA hitherto unknown synthetic access to alkali lithosilicates, a substance class first described by Hoppe in the 1980s, is reported. With the synthesis and characterization of NaK7[Li3SiO4]8, a new representative has been discovered, expanding the family of known alkali lithosilicates. Astonishingly, NaK7[Li3SiO4]8 and the already established alkali lithosilicates Na[Li3SiO4] as well as K[Li3SiO4] display unforeseen luminescence properties, when doped with Eu2+. Na[Li3SiO4]:Eu2+ exhibits an ultra‐narrow blue, K[Li3SiO4]:Eu2+ a broadband, and NaK7[Li3SiO4]8:Eu2+ a yellow‐green double emission upon excitation with near‐UV to blue light. Consequently, all of the investigated substances of this class of compounds are highly interesting phosphors for application in phosphor converted LEDs.
Autism spectrum disorder symptoms from ages 2 to 19 years: Implications for diagnosing adolescents and young adults
Authors: Bal Vanessa H. , Kim So‐Hyun , Fok Megan , Lord Catherine 
Published: August 2018

This study explored change in social‐communicative symptoms in 140 individuals with childhood autism spectrum disorder (ASD) diagnoses. Trajectories of caregiver‐reported social‐communicative symptoms were examined for three groups (verbal, delayed speech, minimally verbal) from ages 2 to 19 years. Groups showed comparable levels of social‐communicative impairment at 2 years and significant decreases in overall symptom levels across the 17‐year period (P < .001). Across three subdomains, main effects of time and language (P < .001) reflected patterns of overall improvement, although children with more impaired language tended to have more caregiver‐reported symptoms relative to verbal peers. A significant time‐by‐language interaction (P < .001) reflected that trajectories of socioemotional reciprocity symptoms differed according to patterns of language development. In contrast, improvements in the nonverbal communication domain were seen across language groups, whereas deficits in the development and maintenance of relationships improved for only verbal children. Verbal adults showed significant reductions in the prevalence of kseveral symptoms exhibited during childhood. Improvements suggest that symptoms indicative of ASD in young children may no longer be diagnostic markers in adolescents and adults. Relative stability of several items suggests that impaired facial expression may be a core ASD symptom that warrants more systematic study across the lifespan. Research investigating the manifestation of ASD in older individuals is needed to foster development of appropriate assessment tools and interventions. Differential relationships to developmental factors within the broader social‐communication domain underscores a need to focus on more narrowly defined symptom constructs when exploring links between pathophysiology and observable phenotypes. Autism Research 2019, 12: 89–99. © 2018 International Society for Autism Research, Wiley Periodicals, Inc.Lay SummaryIn a sample of 140 participants with autism spectrum disorder (ASD) followed from 2 to 19 years old, this study found that overall social‐communicative symptoms improve across childhood and adolescence. However, timing and amount of change varied for different symptom categories and participants with different language abilities. Findings suggest that some older adolescents and adults with ASD may not exhibit the same difficulties observed in young children with ASD. More research is needed to better understand the strengths and needs of young adults with ASD.

Abstract

Background
The aim of this study was to assess factors associated with outcomes after surgery for colorectal cancer and to design and internally validate a simple score for predicting perioperative mortality.

Methods
Patients undergoing surgery for primary invasive colorectal cancer in 22 centres in Spain between June 2010 and December 2012 were included. Clinical variables up to 30 days were collected prospectively. Multiple logistic regression techniques were applied and a risk score was developed. The Hosmer–Lemeshow test was applied and the area under the receiver operating characteristic (ROC) curve (AUC, with 95 per cent c.i.) was estimated.

Results
A total of 2749 patients with a median age of 68·5 (range 24–97) years were included; the male : female ratio was approximately 2 : 1. Stage III tumours were diagnosed in 32·6 per cent and stage IV in 9·5 per cent. Open surgery was used in 39·3 per cent, and 3·6 per cent of interventions were urgent. Complications were most commonly infectious or surgical, and 25·5 per cent of patients had a transfusion during the hospital stay. The 30-day postoperative mortality rate was 1·9 (95 per cent c.i. 1·4 to 2·4) per cent. Predictive factors independently associated with mortality were: age 80 years or above (odds ratio (OR) 2·76), chronic obstructive pulmonary disease (COPD) (OR 3·62) and palliative surgery (OR 10·46). According to the categorical risk score, a patient aged 80 years or more, with COPD, and who underwent palliative surgery would have a 23·5 per cent risk of death within 30 days of the intervention.

Conclusion
Elderly patients with co-morbidity and palliative intention of surgery have an unacceptably high risk of death.
Electrocatalytic Study of the Thin Metallopolymer Film of [2,2′‐{1,2‐Ethanediylbis[Nitrilo(1E)‐1‐Ethyl‐1‐Ylidene]}Diphenolate]‐Nickel(II) for Ethanol Electrooxidation

Published: August 2018

AbstractThe present paper describes the electrochemical activity of a Ni(II)‐Schiff base metallopolymer electrode for the oxidation of ethanol in alkaline media. The scanning electron microscope results show that the metallopolymer at the glassy carbon surface has a nanoflake‐like lamellar structure, and there is no molecular structural change after treatment with NaOH. Voltammetry measurements indicate that the metallopolymer acts as efficient material for the electrocatalytic oxidation of ethanol, where a high‐valent nickel(IV) was revealed as the reactive intermediate during the anodic scan. An isopotential point can be observed in rotating disk electrode voltammetry for ethanol oxidation. The electrode surface may be considered to consist of two independent electrochemical regions, one corresponding to the ethanol electro‐oxidation by nickel(IV) and the second corresponding to water oxidation. The Tafel slopes were found to be 246 mV dec−1 at low overpotentials and 44 mV dec−1 at high overpotentials, which suggest that the first electron transfer step is the rate controlling step. The specific activity of the metallopolymer‐modified electrode for the ethanol electro‐oxidation reaction was 6.66 mA cm−2 for 0.130 μmol cm−2 of electroactive species of metallopolymer at 0.6 V vs. SCE.
