Authors: Carsana Chiara 
Published: May 2015

Le sujet de l’article porte sur la fonction et la réélaboration des discours politiques dans l’historiographie antique. Dans une première partie, les enjeux de la problématique sont mis en évidence. Dans une seconde partie est présenté un cas ponctuel, à savoir celui de l’histoire des Guerres Civiles d’Appien d’Alexandrie. En conclusion : Appien part des données réelles de discours effectivement prononcés ; il les réélabore en suivant à chaque fois une démarche différente, mais qui est conditionnée par la vision d’ensemble qu’il se propose de faire partager au lecteur.
Rituels démocratiques et mise en scène de la participation populaire dans les assemblées du budget participatif à Recife (Brésil)
Authors: Goirand Camille 
Published: May 2015

Cet article rend compte d’une enquête sur les assemblées consacrées à l’élaboration participative du budget municipal à Recife. Une première partie présente un état de la recherche sur les dispositifs participatifs au Brésil et en discute les approches dominantes. Une seconde décrit le contexte politique dans lequel l’offre participative a été conçue par le Parti des Travailleurs, au pouvoir à Recife (2001-2012). Les deux dernières parties montrent que l’espace public qui émerge des assemblées est occupé par les corps et le bruit, construit dans une mise en scène du « populaire », hiérarchisé dans ses configurations spatiales, orienté et encadré par les pouvoirs publics. Enfin, l’article montre que les sens de la participation, multiples, convergent vers l’idée que participer, c’est « être là ».

Published: May 2015

AbstractForest fires generate large amounts of ash and biochar, or black carbon (BC), that cover the soil surface, interacting with the soil’s constituents and its seedbank. This study concerns reproductive ecology assessments supported by molecular characterisation to improve our understanding of the effects of fire and fire residues on the germination behaviour of 12 arboreal species with a wide geographic distribution. For this purpose, we analysed the effects of three ash and one BC concentration on the germination of Acacia dealbata Link, A. longifolia (Andrews) Willd., A. mearnsii De Wild., A. melanoxylon R. Br., Pinus nigra Arnold, P. pinaster Aiton, P. radiata D. Don, P. sylvestris L., Quercus ilex L., Q. pyrenaica Willd., Q. robur L., and Q. rubra L. Each tree species was exposed to ash and BC created from its foliage or twigs (except for Q. rubra, which was exposed to ash and BC of Ulex europaeus L.). We monitored germination percentage, the T50 parameter, and tracked the development of germination over time (up to 1 yr). The BC of A. dealbata, P. pinaster, and Q. robur was analysed by pyrolysis-gas chromatography-mass spectrometry (PY-GC-MS) to assess the molecular composition. In six species, ash inhibited the germination, while in another five species, germination was not affected by ash or by BC. In Q. rubra, ash and BC stimulated its germination. This stimulating effect of the BC on Q. rubra is likely to be related to the chemical composition of the ash and BC obtained from Ulex feedstock. The BC of U. europaeus has a very different molecular composition than the other BC samples analysed, which, together with other factors, probably allowed for its germination stimulating effects.

Background: Type 2 diabetes is a chronic disease that presents a significant burden on health care systems in many countries. With the rise of obesity, the incidence of Type 2 diabetes has also been steadily increasing. A healthy lifestyle and understanding of diabetes management are important factors for delaying the onset of comorbidities associated with Type 2 diabetes. The objective of this study was to evaluate the self-perception of health in individuals with Type 2 diabetes as it relates to BMI status, which has important implications for the implementation of preventive programs. Methods: A cross-sectional lifestyle survey was implemented in the region of Celaya, Guanajuato, Mexico, targeting 100 participants diagnosed with Type 2 diabetes. Anthropometric measurements and participant characteristics were also obtained. Fisher’s exact test was used to determine if the proportions of lifestyles perceptions differed by BMI status. Results: Participants had a mean age of 56.12 ± 10.26, a mean BMI of 29.13 ± 5.48 kg/m2, were mostly married (67.0%), and female (70.0%). None of the normal weight participants perceived themselves as unhealthy. 95% of overweight/obese participants perceived themselves to be healthy, despite a diagnosis of diabetes and being overweight/obese, while only 5% perceived themselves to be unhealthy. However, these differences in the perceptions of health classified by BMI status were not statistically significant (p = 0.42).Conclusion: Our findings indicate that overweight and obese persons with Type 2 diabetes in Celaya, Mexico may have misperceptions about their own health, even though these findings were not statistically significant. These preliminary data highlight the importance of implementing prevention and educational programs among those with diabetes, in order to combat health misperceptions and raise awareness about the dangers of diabetes and obesity. Furthermore, more research with larger sample sizes is needed in order to fully understand the effects of perception of health on actual health.

De la mesure du temps à l’analyse des séquences d’action. Dynamique de l’attention dans les études du public des musées
Authors: Coavoux Samuel 
Published: May 2015

Cet article analyse l’usage des données spatio-temporelles dans les enquêtes de public mobilisant le suivi chronométré de visiteurs d’exposition. Il met en lumière un paradoxe : ces études emploient des données séquentielles, des suites ordonnées de coordonnées spatio-temporelles, mais elles produisent des analyses ne tenant aucun compte de la temporalité de l’activité de visite. Nous avançons deux explications. D’une part, la perspective d’évaluation des expositions qui domine dans ces enquêtes incite les chercheurs à transformer l’échelle de leur analyse en passant de données centrées sur les individus à des analyses centrées sur les objets exposés. D’autre part, la standardisation des outils n’a pas favorisé l’adoption de techniques d’analyse séquentielle. Nous présentons enfin, à partir des résultats d’une enquête ethnographique sur les réceptions muséales d’une toile de maître, quelques pistes d’analyse rendant compte de la temporalité de la visite.
Revisiting viscoelastic effects on interseismic deformation and locking degree: A case study of the Peru‐North Chile subduction zone
Authors: Li Shaoyang , Moreno Marcos , Bedford Jonathan , Rosenau Matthias , Oncken Onno 
Published: May 2015

AbstractViscoelastic effects potentially play an important role during all phases of the earthquake cycle in subduction zones. However, most current models neglect such effects in the interseismic deformation pattern. Here we use finite element method (FEM) models to investigate the control of viscoelasticity on interseismic deformation and to highlight the pitfalls of interpreting the data with purely elastic models for both the forward and inverse problems. Our results confirm that elastic models are prone to overestimating the interseismic locking depth, a crucial parameter for estimating the maximum possible earthquake magnitude. The application of the viscoelastic model improves the fit to the interseismic deformation, especially in the inland area. Additionally, we construct 3‐D FEM models constrained by geophysical and GPS data and apply our methodology to the Peru‐North Chile subduction zone. Our results indicate that viscoelastic effects contribute significantly to the observed GPS data. The signals interpreted as back‐arc shortening in the elastic model can be alternatively explained by viscoelastic deformation, which, in turn, dramatically refines the interseismic locking pattern in both dip and strike directions. Our viscoelastic locking map exhibits excellent correlation with the slip distributions of previous earthquakes, especially the recent 2014 Mw 8.1 Iquique earthquake. The incorrect elastic assumptions affect the analysis of interseismic deformation with respect to slip deficit calculations. Our results thus suggest that it is necessary to thoroughly reevaluate existing locking models that are based on purely elastic models, some of which attribute viscoelastic deformation to different sources such as microplate sliver motions.
Suppression Mechanism for Enol–Enol Isomerization of 2‐Substituted Dimedones
Authors: China Hideyasu , Okada Yutaka , Dohi Toshifumi 
Published: May 2015

Abstract2‐Substituted dimedones, described as having a simple chemical structure, are a type of cyclic β‐diketone with enol–enol interconversion. The influence of the enol‐enol isomerism interferes with structure analysis of many dimedones in solution by NMR spectroscopy. It was demonstrated that the isomerism of the 2‐substituted dimedones depends on solvent, time, solute concentration, and temperature. Negative activation energy of the isomerization was determined by the NMR line shape and spin‐spin relaxation analyses, which is an extraordinary phenomenon found for the first time in the molecular dynamics of NMR. Suppression of the isomerization by heating, dilution of the solute, and time control in several low‐polarity solvents enabled analysis of the enol form in detail. It was clarified that deceleration of the intramolecular chemical exchange rate in the isomerization was responsible for the decrease in the intermolecular hydrogen‐bonding effect in the suppression mechanism.
Numerical study of co‐axial bubble coalescence characteristics

Published: May 2015

AbstractBubble coalescences have a significant role in petroleum and chemical industries for proper mixing, good heat and mass transfer between the gas and liquid phases. In this study, the volume of fluid method has been used to model for investigation of co‐axial bubble coalescence dynamic evolution in stagnant fluid. The CSF method was incorporated as a source term in the momentum equation to track the motion of the bubble and liquid interface. The effects of Bond number ranges, Bo ~ 4.09–50 (variation of the surface tension) and Reynolds number range, Re ~ 0.98–120 (variation of the liquid viscosity) were investigated. Significant effects were observed in the process of bubble coalescence on the shape of bubbles when the viscosity ratio (μr), and density ratio (ρr) were kept constant. The changes in bubble shape with progressing time were validated by the experimental observation of available literature. For low Bo and Re, the late coalescence of the bubbles was found, whereas the shape of the succeeding bubbles had changed significantly. The same ratio of Bo/μr and Bo/Re does not affect the bubble coalescence process, if Bo, μr and Re is reduced to 82%. By the study of co‐axial coalescence of three bubbles, it is found that the liquid‐film rupture and bubble breakup between the middle and third bubble occurs faster for both low and high Re. © 2015 Curtin University of Technology and John Wiley & Sons, Ltd.
Determinants of Tobacco Consumption in Papua New Guinea: Challenges in Changing Behaviours
Authors: Hou Xiaohui , Xu Xiaochen , Anderson Ian 
Published: May 2015

AbstractThis article analyses smoking prevalence and smoking behaviours in Papua New Guinea (PNG). Using the 2009–2010 PNG Household Income and Expenditure Survey, the article analyses the determinants of tobacco use and tobacco choices in PNG. The results show adults (18 years and above) in the poorest quartile are more likely to smoke. Tobacco consumption imposes a large financial burden to poor households. Tobacco consumption accounts for about 23 per cent of total household food expenditure for households in the poorest quartile, as compared with 15 per cent for the entire sample. However, most of these households consume non‐processed tobacco. The study reveals the urgency to control tobacco consumption in PNG and considers some practical challenges that the country may face.
A lightweight privacy‐preserving scheme with data integrity for smart grid communications
Authors: Bao Haiyong , Chen Le 
Published: May 2015

SummarySmart grid, deemed as the next generation of power grid, can efficiently monitor, control, and predicate energy generation and consumption. However, the frequent collection of users' consumption information in smart grid may reveal user's privacy, and the tampering of smart grid communication may also impair the data integrity, subsequently affecting the precise monitoring and controlling at the control center. In this paper, to address the aforementioned challenges, we propose a lightweight data report scheme for smart grid communications, which can achieve privacy preservation and data integrity simultaneously. Specifically, an efficient pseudonym identity‐based privacy‐preserving report approach is proposed for the control center to obtain the fine‐grained usage data of all the users while protecting user's privacy. An online/off‐line hash tree‐based mechanism is also designed to check and assure data integrity of communications. Because of the shifting of most time‐consuming computations to off‐line phase, the online process is very fast and efficient by performing merely the lightweight bottom‐up hash tree verifications to check all users' data integrity concurrently. Furthermore, a topology‐independent data report architecture is also structured, which is adaptable for dynamic residential users to spontaneously form clusters and efficiently report data in flocks. Extensive performance evaluation demonstrates that the proposed scheme can achieve less communication overhead and dramatically reduce computational cost in comparison with the existing schemes.

CyberGIS‐BioScope: a cyberinfrastructure‐based spatial decision‐making environment for biomass‐to‐biofuel supply chain optimization
Authors: Hu Hao , Lin Tao , Liu Yan Y. , Wang Shaowen , Rodríguez Luis F. 
Published: May 2015

SummaryBiomass, for example, energy crops, forests, and agricultural residues, has emerged as a renewable energy option to alleviate the consumption of limited fossil fuel resources and the consequent environmental issues. Designing an effective and efficient biomass‐to‐biofuel supply chain involves sophisticated decision‐making processes, often requiring collaborative work on data integration, model specification, scenario analysis, and coordinated implementation and management. To establish an integrated system for such work, challenges exist in (1) the limited interoperability between bioenergy models and geographic information systems (GIS); (2) interactive scenario construction, evaluation, and sharing; and (3) complex optimization problem solving that requires advanced cyberinfrastructure resources to support interactive decision‐making. To resolve these challenges, this paper describes CyberGIS‐BioScope, an interactive and collaborative cyberGIS‐based spatial decision‐making environment for biomass‐to‐biofuel supply chain optimization. The CyberGIS‐BioScope takes advantage of cyberGIS capabilities to process and analyze spatial data and enhance visualization and sharing of optimization results. Meanwhile, the integrated environment makes the complex optimization model and advanced cyberinfrastructure resources easily accessible for agricultural scientists and decision‐makers and thus accelerates their scientific discovery and decision‐making processes.

Authors: Chen Zhe , Yang Lei , Hang Yin , Wang Xiangyong 
Published: May 2015

Cerium‐doped terbium gallium garnet single crystal having a large Verdet constant was grown by floating zone (FZ) method, which was suitable for the use in optical devices. The lattice parameters and the X‐ray rocking curve measurement of the crystal was determined by X‐ray diffraction analysis. The Verdet constant of the crystal (B = 0.55 T) at the wavelength of 632.8 nm was −165.8 rad m−1 T−1 at room temperature, 23.7% larger than that of pure TGG (−134.0 rad m−1 T−1). The performance of the high optical quality and excellent magneto‐optical properties of the crystal shows the great potential of using this new method to meet the increasing demand of VI‐NIR Faraday rotators.

AbstractConstructing three‐dimensional (3 D) nanostructures with excellent structural stability is an important approach for realizing high‐rate capability and a high capacity of the electrode materials in lithium‐ion batteries (LIBs). Herein, we report the synthesis of hydrangea‐like amorphous mixed‐valence VOx microspheres (a‐VOx MSs) through a facile solvothermal method followed by controlled calcination. The resultant hydrangea‐like a‐VOx MSs are composed of intercrossed nanosheets and, thus, construct a 3 D network structure. Upon evaluation as an anode material for LIBs, the a‐VOx MSs show excellent lithium‐storage performance in terms of high capacity, good rate capability, and long‐term stability upon extended cycling. Specifically, they exhibit very stable cycling behavior with a highly reversible capacity of 1050 mA h g−1 at a rate of 0.1 A g−1 after 140 cycles. They also show excellent rate capability, with a capacity of 390 mA h g−1 at a rate as high as 10 A g−1. Detailed investigations on the morphological and structural changes of the a‐VOx MSs upon cycling demonstrated that the a‐VOx MSs went through modification of the local VO coordinations accompanied with the formation of a higher oxidation state of V, but still with an amorphous state throughout the whole discharge/charge process. Moreover, the a‐VOx MSs can buffer huge volumetric changes during the insertion/extraction process, and at the same time they remain intact even after 200 cycles of the charge/discharge process. Thus, these microspheres may be a promising anode material for LIBs.
DC tolerance analysis of electronic circuits by polyhedral circuits
Authors: Pastore Stefano 
Published: May 2015

SUMMARYReal equilibrium solutions of electronic circuits are affected by deviation of real characteristics of devices from their nominal values, producing the displacement of solution points from their nominal position. In this paper, a method to determine all the equilibrium regions in which real equilibrium points may fall is presented. The analysis is based on the introduction of the so‐called strip characteristics that represent the characteristics of devices affected by tolerances. They are modeled by polyhedral characteristics. Different situations may occur as tolerances grow. A nominal solution point may disappear, or on the other end, some solution point not present with nominal characteristics may appear. These possible events call for a classification of the equilibrium regions in either certain or uncertain, depending on the existence or not of an equilibrium point for any choice of real characteristics. The algorithm adopts linear programming techniques and a clustering algorithm. Copyright © 2015 John Wiley & Sons, Ltd.

Published: May 2015

AbstractAmongst the various conversions that are known to transform the furan moiety into other functional groups or heterocyclic rings, the Achmatowicz reaction and the corresponding aza‐modification stand out as broadly applicable oxidative rearrangements. Both reactions are synthetically useful transformations resulting either in pyranone or piperidinone structures, containing ample synthetic opportunities for further functionalization. In this review, we will provide a literature overview of the aza‐Achmatowicz reaction, including application of the resulting piperidinones in the synthesis of biologically active compounds and natural products.

ABSTRACTBackgroundThe purpose of this phase II trial was to evaluate the tolerability, safety, and efficacy of a non–5‐fluorouracil (5‐FU)‐based induction chemotherapy followed by chemoradiotherapy (CRT) for patients with locally advanced head and neck squamous cell carcinoma (HNSCC).MethodsSixty patients with stage III to IV HNSCC were treated with induction paclitaxel and cisplatin (TP; paclitaxel 175 mg/m2 and cisplatin 80 mg/m2, 3 cycles) followed by CRT (cisplatin 100 mg/m2; D1, 22, and 43 of radiotherapy).ResultsFifty‐six patients (93.3%) completed 3 cycles of induction TP (no treatment‐related deaths), 52 (86.7%) completed definitive CRT per protocol (adverse event [AE] grade ≥2 in 53.3%). The overall response rate after induction TP was 82.5% for patients with resectable disease and 55.5% for unresectable disease (p = .023), and complete response (CR) rate after CRT was 70.0% for patients with resectable disease and 30.0% for unresectable disease (p = .005).ConclusionInduction TP followed by cisplatin based‐CRT was well‐tolerated, safe, and had high overall response rate in selected patients with locally advanced HNSCC. © 2015 Wiley Periodicals, Inc.
