Improvement in the Reliability of AOAC Official Method 2012.15 for Iodine
Authors: Hieda Naoto , Ikeuchi Yoshihiro , Matsuno Ichirou 
Published: September 2018

Abstract
Background: Reliable measurements of iodine are essential for ensuring the qualityof infant formula. The AOAC Official Method 2012.15 for iodine tends to produce higher results in the presence of carbon remaining in the final test solution after digestion with alkaline dissolution. This is partly because of the lack of countermeasures for signal enhancement induced by coexisting carbon in Method 2012.15. Objective: To obtain more reliable values for infant formulas, we undertook an experiment. Methods: We modified the protocol by addingcarbon in the form of methanol to both the standardsolutions and the final test solutions. Comparisonsof the enhancement factor for iodine-127 were usedto find the optimized concentration of methanol from0–10%. Results: Optimization of the additional carbon showed that a 5% methanol minimum was necessary for a constant ratio of iodine. The results exhibited good linearity (coefficient of determination &gt;0.999), and the LOQ was 0.19 μg/100 g for the reconstituted final product with a methanol concentration of 5%. The intermediate precision RSD was &lt;3.76%, and the recovery factor was 97.5–104.2% for infant formula distributed in several countries and a special formula distributed in Japan. Conclusions: This demonstrates that 5% methanol, when addedto standard and final solutions, acts as an effective matrix matching agent. Highlights: This modified method produces more accurate iodine quantification in infant formulas and special formulas in which there is incomplete digestion of the matrix.
La performativité du corps féminin dans le théâtre de Haentjens : quatre illustrations
Authors: Lalonde Gabrielle 
Published: September 2018

Le thème du corps féminin occupe une place centrale dans l’univers théâtral de Brigitte Haentjens. Depuis la fondation de Sibyllines, elle élabore, dans ses mises en scène, des personnages s’inscrivant dans un imaginaire féminin qui feint la normativité, jusqu’à ce que, à force de répétition, leur image se torde et en vienne à se contredire elle-même. Ici, nous exposons quatre dimensions de cette représentation conflictuelle : celle de la structure rythmique du mouvement chorégraphique des corps en scène, du personnage démultiplié dans la forme chorale, de l’apparat vestimentaire des femmes en scène et du langage gestuel qu’elles développent. L’étude s’appuie sur des exemples tirés de trois spectacles : Hamlet-machine (2001), La cloche de verre (2003) et Médée-Matériau (2004).

Published: September 2018

La question du premier roman a suscité ces dernières années l’intérêt des
chercheurs, mais la figure du primo romancier n’a pas été abordée sous l’angle de sa notice
biographique. Si les travaux des sociologues de la littérature tendent à faire reposer
l’identité de l’écrivain sur des principes de singularité, qu’en est-il spécifiquement pour
le primo romancier, nouvel entrant dans le champ littéraire ? Et comment l’éditeur
parvient-il à faire valoir cet auteur en principe peu connu ? Pour répondre à ces questions,
cet article analyse les notices biographiques de 169 auteurs ayant publié un premier roman
dans les dix dernières années (2007-2016), telles que présentées sur les sites Internet de
huit éditeurs québécois.
Patrimonialisation et mise en tourisme : une double entrée pour questionner le rapport à l’espace et au temps
Authors: Ouellet Annie 
Published: September 2018

Cette contribution s’intéresse au double processus de mise en tourisme et en patrimoine des centres-villes « historiques », de même qu’à la coprésence des individus les habitant (de façon permanente ou temporaire), soit les résidents permanents et les touristes. Cette double entrée par le tourisme et par le patrimoine amène à nous interroger tout particulièrement sur les rapports à l’espace et au temps. Si la dimension spatiale des rapports sociaux que nous appréhendons demeure relativement constante, soit le centre d’une ville patrimonialisée et mise en tourisme, ce sont trois dimensions temporelles qui seront abordées comme autant d’angles d’analyse. Seront donc considérés le temps du quotidien (et du hors-quotidien (Équipe MIT, 2002)), le temps des saisons et le temps des « mémoires patrimoniales » (Morisset, 2009). Notre propos s’appuie, pour partie, sur un travail d’enquête mené dans les petites villes françaises de Sarlat (Dordogne) et Dinan (Côtes-d’Armor).

AbstractObjectiveCaffeine therapy for apnea of prematurity has been reported to improve brain white matter microstructure at term‐equivalent age, but its long‐term effects are unknown. This study aimed to investigate whether caffeine affects (1) brain structure at 11 years of age, and (2) brain development from term‐equivalent age to 11 years of age, compared with placebo.MethodsPreterm infants born ≤1250 g were randomly allocated to caffeine or placebo. Magnetic resonance imaging (MRI) was performed on 70 participants (33 caffeine, 37 placebo) at term‐equivalent age and 117 participants (63 caffeine, 54 placebo) at 11 years of age. Global and regional brain volumes and white matter microstructure were measured at both time points.ResultsIn general, there was little evidence for differences between treatment groups in brain volumes or white matter microstructure at age 11 years. There was, however, evidence that the caffeine group had a smaller corpus callosum than the placebo group. Volumetric brain development from term‐equivalent to 11 years of age was generally similar between treatment groups. However, there was evidence that caffeine was associated with slower growth of the corpus callosum, and slower decreases in axial, radial, and mean diffusivities in the white matter, particularly at the level of the centrum semiovale, over time than placebo.InterpretationThis study suggests any benefits of neonatal caffeine therapy on brain structure in preterm infants weaken over time and are not clearly detectable by MRI at age 11 years, although caffeine may have long‐term effects on corpus callosum development.
Highly Transparent, Deformable, and Multifunctional AgPdCu/ITO/PTFE Hybrid Films for Self‐Cleaning, Flexible, and Energy‐Saving Smart Windows
Authors: Lee Sang‐Mok , Park Jin‐Yeong , Kim Han‐Ki 
Published: September 2018

AbstractRollable, bendable, twistable, and foldable polymer–oxide–metal multistacked hybrid films are demonstrated, which simultaneously act as multifunctional electrodes in flexible polymer‐dispersed liquid crystal (PDLC) windows and flexible and transparent thin‐film heaters (TFHs) for self‐cleanable and flexible smart windows. By continuous sputtering of a thin polytetrafluoroethylene (PTFE)–indium tin oxide (ITO)–AgPdCu (APC) multilayer on a colorless polyimide substrate, transparent and multifunctional films are fabricated with a low sheet resistance of 7 Ω □−1, high optical transmittance of 83% at a wavelength of 550 nm, low transmittance in the infrared region, and a high contact angle of 109°. Based on inner/outer bending, rolling, twisting, and folding tests, the outstanding flexibility of these PTFE/ITO/APC multistacked films is demonstrated. The flexible PDLC and flexible TFHs with PTFE/ITO/APC multistacked electrodes show a controllable transmittance range between the on and off states that is nearly 40%, and a high saturation temperature of 111 °C is observed at a low applied voltage of 4 V. The multifunctional properties of the flexible PDLC and TFHs fabricated on PTFE/ITO/APC hybrid films indicate that the polymer–oxide–metal hybrid film is a versatile transparent electrode that can be used for flexible, smart, and energy‐saving windows.
Biotransporting Biocatalytic Reactors toward Therapeutic Nanofactories
Authors: Nishimura Tomoki , Akiyoshi Kazunari 
Published: September 2018

AbstractDrug‐delivery systems (DDSs), in which drug encapsulation in nanoparticles enables targeted delivery of therapeutic agents and their release at specific disease sites, are important because they improve drug efficacy and help to decrease side effects. Although significant progress has been made in the development of DDSs for the treatment of a wide range of diseases, new approaches that increase the scope and effectiveness of such systems are still needed. Concepts such as nanoreactors and nanofactories are therefore attracting much attention. Nanoreactors, which basically consist of vesicle‐encapsulated enzymes, provide prodrug conversion to therapeutic agents rather than simple drug delivery. Nanofactories are an extension of this concept and combine the features of nanoreactors and delivery carriers. Here, the required features of nanofactories are discussed and an overview of current strategies for the design and fabrication of different types of nanoreactors, i.e., systems based on lipid or polymer vesicles, capsules, mesoporous silica, viral capsids, and hydrogels, and their respective advantages and shortcomings, is provided. In vivo applications of biocatalytic reactors in the treatment of cancer, glaucoma, neuropathic pain, and alcohol intoxication are also discussed. Finally, the prospects for further progress in this important and promising field are outlined.

AbstractThe industrial artificial fixation of atmospheric N2 to NH3 is carried out using the Haber–Bosch process that is not only energy‐intensive but emits large amounts of greenhouse gas. Electrochemical reduction offers an environmentally benign and sustainable alternative for NH3 synthesis. Although Mo‐dependent nitrogenases and molecular complexes effectively catalyze the N2 fixation at ambient conditions, the development of a Mo‐based nanocatalyst for highly performance electrochemical N2 fixation still remains a key challenge. Here, greatly boosted electrocatalytic N2 reduction to NH3 with excellent selectivity by defect‐rich MoS2 nanoflowers is reported. In 0.1 m Na2SO4, this catalyst attains a high Faradic efficiency of 8.34% and a high NH3 yield of 29.28 µg h−1 mg−1cat. at −0.40 V versus reversible hydrogen electrode, much larger than those of defect‐free counterpart (2.18% and 13.41 µg h−1 mg−1cat.), with strong electrochemical stability. Density functional theory calculations show that the potential determining step has a lower energy barrier (0.60 eV) for defect‐rich catalyst than that of defect‐free one (0.68 eV).
Efficient and Stable Inorganic Perovskite Solar Cells Manufactured by Pulsed Flash Infrared Annealing

AbstractOrganic–inorganic perovskite solar cells have achieved impressive power conversion efficiency over the past years, yet operational stability remains the key concern. One strategy to improve long‐term stability is to replace the thermally unstable organic with inorganic cations comprising the perovskite lattice. Here, for the first time, pulsed infrared light is used to drive the crystallization of inorganic mixed halide CsPbIxBr(3−x) perovskite films in solar cells with a power conversion efficiency exceeding 10%. By varying the iodide–bromine ratio systematically, it is found that to keep the inorganic perovskite black phase stable at the room temperature, the iodine content needs to be limited to lower than 60% – bromine content higher than 40%. The finding revises previous reports claiming stable compositions with higher iodine contents, which is systematically exploited to reduce the perovskite bandgap with the aim to enlarge the light absorption spectra and thus to boost the device efficiency. It is demonstrated that the newly defined stable compositional range enables devices that retain 90% of the efficiency after stressing the perovskite at 200 °C for 1 h. This result demonstrates that inorganic halide perovskites are stable materials for high‐temperature applications such as concentrated photovoltaics.

AbstractThe impact of physical activity (PA) on lymphoma survival is not known. The association of PA and change in PA with overall (OS), lymphoma‐specific (LSS) and event‐free (EFS) survival was evaluated in a prospective cohort of newly diagnosed lymphoma patients (2002‐2012). We calculated Leisure Score Indexes (mLSI) from the self‐reported usual adult PA (baseline) and at 3‐years post‐diagnosis (FU3), grouping patients by active vs insufficiently active by the American Cancer Society PA guidelines. Associations of PA with survival were assessed using hazard ratios (HRs) and 95% confidence intervals (CI) from Cox models stratified by lymphoma subtype, adjusted for age, sex, baseline BMI, and comorbidity score with change scores further adjusted for baseline PA. Three thousand sixty participants were evaluable at baseline and 1371 at FU3. Active patients had superior survival from baseline [HR (CI): OS 0.82 (0.72‐0.94); LSS 0.74 (0.61‐0.90); EFS 0.92 (0.82‐1.02)] and FU3 [HR (CI): OS 0.64 (0.46‐0.88); LSS 0.32 (0.18‐0.59); EFS 0.82 (0.61‐1.10)] compared to insufficiently active. An increase in mLSI from baseline to FU3 (vs stable mLSI) was associated with superior OS (HR = 0.70, CI 0.49‐1.00) and LSS (HR = 0.49, CI 0.26‐0.94).The continuous change in mLSI at FU3 was significantly associated with OS, LSS and EFS; maintained across subgroups and appeared linear. Higher PA among lymphoma patients at diagnosis and 3 years is significantly associated with OS, LSS, and EFS. Increasing PA after diagnosis is significantly associated with improved OS and LSS supporting an important role for PA in lymphoma survivorship and the need for intervention trials.
Preparation and electrochemical performance of modified Ti3C2Tx/polypyrrole composites

Published: September 2018

ABSTRACTMXenes with a large surface area have been widely studied to improve the pseudocapacitance of electrode materials by combining conductive polymer materials. In this article, a superficial strategy to enhance the electrochemical properties by in situ polymerization of a pyrrole monomer between the Ti3C2Tx layers modified with 1,5‐naphthalene disulfonic acid (NA) and cetyltrimethylammonium bromide (CTAB) was investigated. It is found that polypyrrole (PPy) and Ti3C2Tx can be combined through strong interactions between each other, and the specific capacitance of the modified Ti3C2Tx/PPy composite was increased to a maximum value of 437 F g−1, which was more than thrice higher than that of pure PPy. The composite also exhibited good cycling performance (76% capacitance retention after 1000 cycles). Moreover, owing to the synergistic effect between the PPy and Ti3C2Tx layers, the composite provided better electron or ion transfer and surface redox processes than that of pure PPy, which indicated that this composite can be used as a promising electrode material for supercapacitors. © 2018 Wiley Periodicals, Inc.

Behavioral predictors of improved speech output in minimally verbal children with autism
Authors: Chenausky Karen , Norton Andrea , Tager‐Flusberg Helen , Schlaug Gottfried 
Published: September 2018

We investigated the relationship between eight theoretically motivated behavioral variables and a spoken‐language‐related outcome measure, after 25 sessions of treatment for speech production in 38 minimally verbal children with autism. After removing potential predictors that were uncorrelated with the outcome variable, two remained. We used both complete‐case and multiple‐imputation analyses to address missing predictor data and performed linear regressions to identify significant predictors of change in percent syllables approximately correct after treatment. Baseline phonetic inventory (the number of English phonemes repeated correctly) was the most robust predictor of improvement. In the group of 17 participants with complete data, ADOS score also significantly predicted the outcome. In contrast to some earlier studies, nonverbal IQ, baseline levels of expressive language, and younger age did not significantly predict improvement. The present results are not only consistent with previous studies showing that verbal imitation and autism severity significantly predict spoken language outcomes in preschool‐aged minimally verbal children with autism, but also extend these findings to older minimally verbal children with autism. Autism Res 2018, 11: 1356–1365. © 2018 International Society for Autism Research, Wiley Periodicals, Inc.Lay SummaryWe wished to understand what baseline factors predicted whether minimally verbal children with autism would improve after treatment for spoken language. The outcome measure was change in percentage (%) syllables approximately correct on a set of 30 two‐syllable words or phrases. Fifteen were both practiced in treatment and tested; the remainder were not practiced in treatment, but only tested, to assess how well children were able to generalize their new skills to an untrained set of words. Potential predictors tested were sex, age, expressive language, phonetic inventory (the number of English speech sounds repeated correctly), autism severity, and nonverbal IQ. Phonetic inventory and (for some children) autism severity predicted children's posttreatment improvement. Nonverbal IQ and expressive language ability did not predict improvement, nor did younger age, suggesting that some older children with autism may be candidates for speech therapy.

BackgroundThe 2016 Zika public health response in the United States highlighted the need for birth defect surveillance (BDS) programs to collect population‐based data on birth defects potentially related to Zika as rapidly as possible through enhanced case ascertainment and reporting. The National Birth Defects Prevention Network (NBDPN) assessed BDS program activities in the United States before and after the Zika response.MethodsThe NBDPN surveyed 54 BDS programs regarding activities before and after the Zika response, lessons learned, and programmatic needs. Follow‐up emails were sent and phone calls were held for programs with incomplete or no response to the online survey. Survey data were cleaned and tallied, and responses to open‐ended questions were placed into best‐fit categories.ResultsA 100% response rate was achieved. Of the 54 programs surveyed, 42 reported participation in the Zika public health response that included BDS activities. Programs faced challenges in expanding their surveillance effort given the response requirements but reported mitigating factors such as establishing and enhancing partnerships and program experience with surveillance and clinical activities. Beyond funding, reported program needs included training, surveillance tools/resources, and availability of clinical experts.ConclusionsExisting BDS programs with experience implementing active case‐finding and case verification were able to adapt their surveillance efforts rapidly to collect and report data necessary for the Zika response. Program sustainability for BDS remains challenging; thus, continued support, training, and resource development are important to ensure that the infrastructure built during the Zika response is available for the next public health response.
Challenging discourses of aspiration: The role of expectations and attainment in access to higher education
Authors: Harrison Neil , Waller Richard 
Published: September 2018

Raising the proportion of young people from disadvantaged backgrounds progressing to higher education has been a key policy objective for successive governments in the UK since the late 1990s. Often this has been conceptualised as a problem with their ‘aspirations’, with the solution being seen as the provision of ‘aspiration‐raising’ activities to promote higher education to those thought to have the potential to progress. Recent large‐scale studies cast strong doubt on this hypothesis by demonstrating that aspirations are not generally low, that different social groups have similar levels of aspiration and that school attainment accounts for nearly all the differences in participation rates between social groups.This article draws on data from a national project exploring efforts to widen participation across two generations of practitioner‐managers in England, focusing on their conceptualisations of the field and their constructions of ‘successful’ activities. It uses the lens of ‘possible selves’ (Markus & Nurius, ) to argue that too much policy emphasis has been placed on the aspirations of young people, rather than either their academic attainment or their expectations, which are shaped by the normative expectations of the adults surrounding them. In addition, the more expansive concepts of widening participation that were present a decade ago have become less common, with a shift towards activities with a clear role in institutional recruitment rather than social transformation. The article concludes with alternative suggestions for policy and practice.
