Future Archaeology: The Speculative Indexicality of Adrian Göllner’s Conceptual Artefacts
Authors: Zdebik Jakub 
Published: August 2017

L’art d’Adrian Göllner repose sur la transposition d’un contenu artistique du passé au présent et à l’avenir. Son art conceptuel est solidement fondé sur la matérialité : il construit ainsi des appareils pour rendre ses concepts visibles. Afin d’explorer ses créations, nous invoquons les concepts du diagramme, de l’index, de la trace graphique et proposons la notion de l’indexicalité spéculative. Ces concepts, d’après les théories de Joselit, Meltzer, Buchloh, Krauss et Iversen, répondent de façon ambigüe à la division entre les arts et les sciences, l’objectivité et la spéculation, les connaissances et les sensations, ce pourquoi ils sont importants dans l’analyse de l’oeuvre de cet artiste qui s’intéresse à l’histoire à travers une expression abstraite et conceptuelle. Les sujets des oeuvres analysées ici touchent la bombe atomique, la réparation d’horloges anciennes, la musique pop des années 1960, l’archéoacoustique, et les blessures mortelles du général Wolfe.
Transformations of Oil: Visibility, Scale, and Climate in Warren Cariou’s Petrography
Authors: French Elysia H. 
Published: August 2017

Dans cet article, j’examine la série Petrography (2014 au présent), dans laquelle Warren Cariou commente sur les perceptions et représentations de l’énergie pétrolière. Utilisant une technique inspirée de Nicéphore Niépce, l’artiste multidisciplinaire winnipegois met en évidence dans ces pétrographies (« petroleum-photography ») une question fondamentale de l’anthropocène : la division continuelle et problématique entre les relations humaines et non humaines, qui découle de la conception du non humain en tant que ressource passive. Mon analyse de cette série met en lumière la façon dont les pétrographies de Cariou réutilisent une ressource naturelle pour attirer notre attention sur notre dépendance au pétrole et la contradiction qui en résulte à cette ère de changement climatique.
Le sens du quotidien en Occident. Du « dernier repas » omnivore aux « premiers repas » végétaux
Authors: Parise Fanny 
Published: August 2017

Le contexte incertain produit une multitude de quêtes de sens pour le consommateur occidental : il se « bricole » une réalité qui rend plus acceptable les « dissonnances cognitives » avec lesquelles il doit composer quotidiennement et qui affecte son régime alimentaire. Les réseaux numériques hébergent une pluralité de nouveaux mangeurs : les praniques, les sans glutens, les végétariens, les crudivores, etc. Ces nouveaux mangeurs souhaitent s’émanciper du système marchand traditionnel, tout en se positionnant non pas en opposition mais en stratège constructiviste du modèle économique actuel. Ces « créatifs culturels » construisent une consommation signifiante où leur interlocution angoissée avec le monde devient ultra-visible. Ils intègrent certains mythes anciens comme l’allégorie chrétienne du « dernier repas » du Christ au sein de leur quotidien afin de bâtir un nouveau cadre normatif ; objectivant un syncrétisme socio-culturel singulier, tout comme l’établissement d’une nouvelle temporalité du rituel.
Une rhétorique de réconciliation
Authors: Nguyen Chi Ai 
Published: August 2017

Suite à la demande de la réforme faite par Vatican II, un nouveau Rituel intitulé « Ordo Paenitentiae » fut publié en 1974. Bien qu’il ait réouvert une fenêtre sur une pratique de l’Église antique, longue de huit siècles, en mettant en oeuvre la célébration communautaire du sacrement de réconciliation avec confession et absolution collectives, ce Rituel romain se tenait encore entre deux théologies, à savoir la théologie de la réconciliation et celle de la pénitence. Plusieurs pays n’ont fait que le traduire, mais les pays francophones ont voulu adapter ce texte en ajoutant certains éléments propres. Dans notre article, en suivant le cadre théorique que propose J.W. O’Malley, nous examinons les notes doctrinales et pastorales de ce Rituel en sa version française, que nous comparons avec la version latine pour repérer les changements au niveau de la forme littéraire, par rapport, par exemple, au concile de Trente. Nous considérons que le Rituel francophone, en se situant dans le mouvement innové par Vatican II, a privilégié la théologie de la réconciliation qui insiste sur la démarche communautaire de ceux qui désirent recevoir le sacrement du pardon.
High-intensity training enhances executive function in children in a randomized, placebo-controlled trial
Authors: Moreau David , Kirk Ian J , Waldie Karen E 
Published: August 2017

Background:Exercise-induced cognitive improvements have traditionally been observed following aerobic exercise interventions; that is, sustained sessions of moderate intensity. Here, we tested the effect of a 6 week high-intensity training (HIT) regimen on measures of cognitive control and working memory in a multicenter, randomized (1:1 allocation), placebo-controlled trial.Methods:318 children aged 7-13 years were randomly assigned to a HIT or an active control group matched for enjoyment and motivation. In the primary analysis, we compared improvements on six cognitive tasks representing two cognitive constructs (N = 305). Secondary outcomes included genetic data and physiological measurements.Results:The 6-week HIT regimen resulted in improvements on measures of cognitive control [BFM = 3.38, g = 0.31 (0.09, 0.54)] and working memory [BFM = 5233.68, g = 0.54 (0.31, 0.77)], moderated by BDNF genotype, with met66 carriers showing larger gains post-exercise than val66 homozygotes.Conclusions:This study suggests a promising alternative to enhance cognition, via short and potent exercise regimens.Funding:Funded by Centre for Brain Research.Clinical trial number:NCT03255499.

AbstractPrevious observations have driven the prevailing assumption in the field that energetic ions measured by an instrument using a bare solid state detector (SSD) are predominantly protons. However, new near‐equatorial energetic particle observations obtained between 7 and 12 RE during Phase 1 of the Magnetospheric Multiscale mission challenge the validity of this assumption. In particular, measurements by the Energetic Ion Spectrometer (EIS) instruments have revealed that the intensities of heavy ion species (specifically oxygen and helium) dominate those of protons at energies
150–220 keV in the middle to outer (>7 RE) magnetosphere. Given that relative composition measurements can drift as sensors degrade in gain, quality cross‐calibration agreement between EIS observations and those from the SSD‐based Fly's Eye Energetic Particle Spectrometer (FEEPS) sensors provides critical support to the veracity of the measurement. Similar observations from the Radiation Belt Storm Probes Ion Composition Experiment (RBSPICE) instruments aboard the Van Allen Probes spacecraft extend the ion composition measurements into the middle magnetosphere and reveal a strongly proton‐dominated environment at
but decreasing proton intensities at
. It is concluded that the intensity dominance of the heavy ions at higher energies (>150 keV) arises from the existence of significant populations of multiply‐charged heavy ions, presumably of solar wind origin.
Process‐based TRIPLEX‐GHG model for simulating N2O emissions from global forests and grasslands: Model development and evaluation

Published: August 2017

AbstractThe development of the new process‐based TRIPLEX‐GHG model derives from the Integrated Biosphere Simulator (IBIS), which couples nitrification and denitrification processes to quantify nitrous oxide (N2O) emissions from natural forests and grasslands. Sensitivity analysis indicates that the nitrification rate coefficient (COENR) is the most sensitive parameter to simulate N2O emissions. Accordingly, we calibrated this parameter using data from 29 global forest sites (across different latitudes) and grassland sites. The average nitrification rate coefficient gradually increases in the order of tropical forest to grassland to temperate forest to boreal forest, and giving means of 0.009, 0.03, 0.04, and 0.09, respectively. This study validated the mean value for each ecosystem at 52 sites globally. Calibration results both indicate the good performance of the model and its suitability in capturing seasonal variation and magnitude of N2O flux; however, it is limited in modeling N2O uptake and increments during periods of snowmelt. Additionally, validation results indicate that simulated and observed annual or seasonal N2O fluxes are highly correlated (R2 = 0.75; P < 0.01). Consequently, our results suggest that the model is suitable in simulating N2O emissions from different forest and grassland land types under varying environmental conditions on a global scale.
Pre‐admonition Suggestion in Live Showups: When Witnesses Learn that the Cops Caught ‘the’ Guy

Published: August 2017

SummaryParticipants (N = 189) witnessed the theft of a computer and were immersed into what they were led to believe was an actual police investigation that culminated in a live showup. After the crime, an officer responded to the scene to take witness statements. Minutes after his arrival, the officer received a radio dispatch that could be heard clearly by the witnesses. The dispatch either stated that the Sherriff had ‘…caught the guy…’ or ‘…detained a suspect who matched the thief's description…’ and instructed the officer to bring the witnesses to identify the suspect. The witnesses then met with two deputies who conducted a live showup with an innocent suspect or the actual culprit. Choosers were more confident than rejecters across all conditions. Also, overhearing the suggestion that the sheriff had caught the guy significantly increased false identifications, and boosted witness confidence in these errors, but did not affect accurate suspect identifications.Copyright © 2017 John Wiley & Sons, Ltd.
Exploring the Relations between Cattell–Horn–Carroll (CHC) Cognitive Abilities and Mathematics Achievement
Authors: Cormier Damien C. , Bulut Okan , McGrew Kevin S. , Singh Deepak 
Published: August 2017

SummaryAs standardized measures of cognitive abilities and academic achievement continue to evolve, so do the relations between the constructs represented in these measures. A large, nationally representative sample of school‐aged children and youth between 6 and 19 years of age (N = 4,194) was used to systematically evaluate the relations between cognitive abilities and components of academic achievement in mathematics. The cognitive abilities of interest were those identified from the Cattell–Horn–Carroll model of intelligence. Specific areas of mathematics achievement included math calculation skills and math problem solving. Results suggest that fluid reasoning (Gf), comprehension‐knowledge (Gc), and processing speed (Gs) have the strongest and most consistent relations with mathematics achievement throughout the school years.Copyright © 2017 John Wiley & Sons, Ltd.

ObjectiveA treat‐to‐target (TTT) strategy is recommended in rheumatoid arthritis (RA). However, health care providers’ adherence to TTT in clinical practice remains unclear. We examined adherence to TTT in RA at US rheumatology sites.MethodsWe used baseline information from the randomized controlled Treat‐to‐Target in RA: Collaboration to Improve Adoption and Adherence trial, which recruited 641 patients from 46 providers practicing at 11 US sites. We obtained data on the implementation of TTT, patient covariates, provider characteristics, and site variables. We examined the implementation of TTT using 4 cardinal features: recording a disease target, recording a disease activity measure, engaging in shared decision‐making, and changing treatment if not at disease target. These features were assessed across sites and providers. We calculated a TTT implementation score as the percentage of features noted. We examined the association between patient, provider, and site covariates and TTT implementation score using proportional odds models.ResultsThe implementation of TTT at baseline was suboptimal: 64.3% of visits had none of the TTT components present, 33.1% had 1 component, 2.3% had 2 components, and 0.3% had all components. The implementation of TTT was significantly different across providers and sites (P < 0.0001 for all). In the multivariable model, we observed that more experience as a rheumatologist was associated with a higher implementation score (P = 0.01 for trend). Compared with fellows, providers with >20 years of experience in practice were more likely to have more TTT components recorded (odds ratio 7.68 [95% confidence interval 1.46–40.52]).ConclusionWe found that adherence to a TTT strategy in RA was suboptimal, and it differed across providers and sites.

AbstractMultifunctional flexible sensors that are sensitive to different physical and chemical stimuli but remain unaffected by any mechanical deformation and/or changes still present a challenge in the implementation of flexible devices in real‐world conditions. This challenge is greatly intensified by the need for an eco‐friendly fabrication technique suitable for mass production. A new eco‐friendly and scalable fabrication approach is reported for obtaining thin and transparent multifunctional sensors with regulated electrical conductivity and tunable band‐gap. A thin (≈190 nm thickness) freestanding sensing film with up to 4 inch diameter is demonstrated. Integration of the freestanding films with different substrates, such as polyethylene terephthalate substrates, silk textile, commercial polyethylene thin film, and human skin, is also described. These multifunctional sensors can detect and distinguish between different stimuli, including pressure, temperature, and volatile organic compounds. All the sensing properties explored are stable under different bending/strain states.

AbstractSlurry casting method dominates the electrode manufacture of lithium‐ion batteries. The entire procedure is similar to the newspaper printing that includes premixing of cast materials into solvents homogeneously, and continuously transferring and drying the slurry mixture onto the current collector. As a market approaching US $80 billion by 2024, the optimization of manufacture process is crucial and attractive. However, the organic solvent remains irreplaceable in the wet method for making slurries, even though it is capital‐intensive and toxic. Here, an advanced powder printing technique is demonstrated that is completely solvent‐free and dry. Through removing the solvent and related procedures, this method is anticipated to statistically save 20% of the cost at a remarkably shortened production cycle (from hours to minutes). The dry printed electrodes outperform commercial slurry cast ones in 650 cycles (80% capacity retention in 500 cycles), and thick electrodes are successfully fabricated to increase the energy density. Furthermore, microscopy techniques are utilized to characterize the difference of electrode microstructure between dry and wet methods, and distinguish dry printing's advantages on controlling the microstructure. In summary, this study proves a practical fabrication method for lithium‐ion electrodes with lowered cost and favorable performance, and allows more advanced electrode designs potentially.

AbstractSilicon doped hafnium oxide was the material used in the original report of ferroelectricity in hafnia in 2011. Since then, it has been subject of many further publications including the demonstration of the world's first ferroelectric field‐effect transistor in the state‐of‐the‐art 28 nm technology. Though many studies are conducted with a strong focus on application in memory devices, a comprehensive study on structural stability in these films remains to be seen. In this work, a film thickness of about 36 nm, instead of the 10 nm used in most previous studies, is utilized to carefully probe how the concentration range impacts the evolution of phases, the dopant distribution, the field cycling effects, and their interplay in the macroscopic ferroelectric response of the films. Si:HfO2 appears to be a rather fragile system: different phases seem close in energy and the system is thus rich in competing phenomena. Nonetheless, it offers ferroelectricity or field‐induced ferroelectricity for elevated annealing conditions up to 1000 °C. Similar to the measures taken for conventional ferroelectrics such as lead zirconate titanate, engineering efforts to guarantee stable interfaces and stoichiometry are mandatory to achieve stable performance in applications such as ferroelectric memories, supercapacitors, or energy harvesting devices.

AbstractThe rich phase diagrams and peculiar physical properties of rare earth perovskite nickelates (RNiO3) have recently attracted much attention. Their electronic structures are highly sensitive to carrier density and bandwidth due to Mott physics. Here, the electrochemically driven giant resistive switching in Pt/RNiO3/Nb‐SrTiO3 heterostructures is reported. Systematic investigation confirms that oxygen vacancies migration modifies the interfacial barrier at the RNiO3/Nb‐SrTiO3 interface and causes the resistive switching behavior. An ON/OFF ratio of about 105 at room temperature is observed, which can be modulated by controlling the oxygen vacancies during sample fabrication or by varying the rare earth element in RNiO3. The findings provide an important step forward toward the development of multifunctional electronic devices based on perovskite nickelates.

Published: August 2017

Novel ZnO/N‐doped helical carbon nanotubes (ZnO/N‐HCNTs) composites were successfully synthesized via a facile chemical precipitation approach at room temperature. The sample was well characterized by X‐ray diffraction (XRD), energy dispersive X‐ray spectroscopy (EDS), transmission electron microscopy (TEM) and ultraviolet–visible diffuse reflectance spectroscopy (UV–vis DRS). The photocatalytic activity was evaluated in the degradation of methylene blue (MB) aqueous solution under UV light irradiation. It is found that ZnO nanoparticles were highly and uniformly anchored on the surface and inner tubes of the N‐HCNTs with size of about 5 nm, and significantly enhanced the photocatalytic activity compared to pure ZnO. The enhanced photocatalytic activity of ZnO/N‐HCNTs composites can be ascribed to the integrative synergistic effect of effective interfacial hybridization between N‐HCNTs and ZnO nanoparticles and the prolonged lifetime of photogenerated electron–hole pairs. Moreover, the ZnO/N‐HCNTs could be easily recycled without any obvious decrease in photocatalytic activity and could be promote their application in the area of environmental remediation.
Malic acid: A novel processing aid for thermoplastic starch/poly(butylene adipate‐co‐terephthalate) compounding and blown film extrusion

Published: August 2017

ABSTRACTThe processing of polysaccharide‐based polymer compounds represents a major challenge because these materials behave considerably different compared to their petro‐based counterparts. Especially in the manufacture of thermoplastic starch (TPS)–polyester films by means of blown film extrusion, an increase in the natural material proportion generally leads to processing difficulties. In addition, higher TPS contents adversely affect mechanical material characteristics. The present study focuses on the effect of malic acid (MA) on processing parameters and on the quality of TPS/poly(butylene adipate‐co‐terephthalate) films. The MA enantiomers d(+) and l(–) as well as the racemate were applied at various concentrations (0.2, 0.4, and 0.8 wt %). Results indicate that the addition of racemic MA at concentrations of 0.2% and 0.4% significantly improved the processibility of TPS. Simultaneously, positive effects such as improved ductility and water sorption characteristics were found. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 45539.
The anthropogenic transformation of an island landscape: Evidence for agricultural development revealed by LiDAR on the island of Efate, Central Vanuatu, South‐West Pacific
Authors: BEDFORD STUART , SIMÉONI PATRICIA , LEBOT VINCENT 
Published: August 2017

ABSTRACTTraditional agricultural systems have been a fundamental research focus of Pacific archaeologists for decades. In many island groups, it has been demonstrated that whole landscapes have been transformed to facilitate increased agricultural production. High‐resolution digital elevation models (DEM) derived from recent LiDAR survey data from Efate, Central Vanuatu, have now revealed that much of that island was completely modified by human activity prior to European contact. There are a range of substantial and more minor linear mound and circular features associated with agricultural development and innovation, of which researchers and contemporary populations are largely unaware. Detailed analysis of the features across one alluvial plain provides some quantification of the scale of landscape modification. These new data radically change perceptions of the Efate landscape and contribute to a range of debates including traditional Pacific Island food production, its surplus and sustainability, sociopolitical development, environmental change and depopulation.
