L’impact de l’acculturation sur le changement de matérialisme
Authors: Benabdallah Mounia , Yassafi Moussa 
Published: December 2017

Les mouvements d’individus d’un pays à l’autre pour des raisons professionnelles (études, expatriation, etc.) ou pour des raisons personnelles (immigration, regroupement familial, etc.) entrainent des changements dans leurs cultures et leurs valeurs dont le matérialisme. À l’aide d’une étude qualitative, nous analysons la relation entre l’acculturation et le matérialisme à travers la possession d’objets désirés, acquis et jugés nécessaires à la vie. Nous étudions les différentes conceptions du matérialisme dans le pays d’origine, le pays d’accueil et chez les individus immigrés. Trois groupes de consommateurs ont été étudiés, à savoir : les Algériens d’Algérie, les Algériens immigrés en France et les Français. Les résultats montrent que la perception du matérialisme diffère selon les cultures et les sous-cultures, que les individus immigrés ont une conception du matérialisme tantôt proche de celle du pays d’origine, tantôt proche de celle du pays d’accueil. La discussion de cet article en apporte l’explication.
De la querelle des universaux à la querelle des comptables au sujet de la Juste Valeur
Authors: Blum Véronique , Laffort Emmanuel 
Published: December 2017

Un débat long de plus d’une décennie témoigne de la rencontre de visions comptables divergentes, opposant les tenants de la Juste Valeur aux défenseurs des coûts historiques. Cette contribution n’entend pas prendre part à ce débat mais suppose un problème plus global et interroge la notion élargie de mesure en comptabilité, dans sa formulation même. Il s’agit dès lors de révéler la manière dont les éventuelles racines d’une querelle inaboutie, par leur agencement ou leur traitement, auraient permis l’émergence d’un malentendu, d’une erreur originelle, au sens où elle se logerait dans les fondements mêmes de la question. Dans une démarche inspirée de la métaphysique, nous employons la méthodologie préconisée par Henri Bergson, pour tenter de délier des entrelacs conceptuels et identifier l’éventuelle équivoque, l’éventuel « faux problème » au sens bergsonien. L’intérêt est double : il permet d’une part de rendre compte d’un quiproquo comme la normalisation comptable en aura peu connu et enfin, d’autre part de s’en dégager par une proposition de reformulation du problème de la mesure comptable.

« Les voix du rebut » : pratiques orales de positionnement social en contexte d’interactions asymétriques
Authors: Machado-Borges Thaïs 
Published: December 2017

Le « rebut » – ce qui est exclu, mis de côté, caché, enterré, ôté de la vue, rejeté – est au point de départ de cet article. Considéré comme matière repoussée, il circule dans les espaces publics et privés, entre les centres de pouvoir et les périphéries oubliées. Vu comme métaphore sociale, il marque les limites entre catégories, entre ce, celui ou celle qui ont de la valeur et ce, celui ou celle qui sont inutiles, bons à jeter. Je m’interroge ici sur l’usage de la parole comme stratégie de positionnement social grâce à l’analyse de quelques interactions du quotidien entre femmes de classes sociales différentes, recueillies à diverses périodes d’un travail de terrain dans le Sud-est brésilien. Comme je le montre, les « voix du rebut », lorsqu’elles sont pratiquées dans des interactions asymétriques, non seulement classent les individus en terme de statut et de valeur, mais aussi renforcent la différence entre des personnes occupant des positions sociales inégales. J’analyse ici les jeux oraux de positionnement lorsque le statut et l’exclusion sociale sont durement négociés.

Abstract. In the present study, a persistent heavy haze episode from 13 to 20 January 2014 in Beijing–Tianjin–Hebei (BTH) is simulated using the WRF-CHEM model through ensemble simulations to investigate impacts of meteorological uncertainties on the haze formation. Model results show that uncertainties in meteorological conditions substantially influence the aerosol constituent simulations at an observation site in Beijing, and the ratio of the ensemble spread to the ensemble mean (RESM) exceeds 50 %. The ensemble mean generally preforms well in reproducing the fine particles' (PM2.5) temporal variations and spatial distributions against measurements in BTH. The meteorological uncertainties do not alter the PM2.5 distribution pattern in BTH principally or dominate the haze formation and development, but remarkably affect the simulated PM2.5 level, and the RESM for the simulated PM2.5 concentrations can be up to 30 % at the regional scale. In addition, the rather large RESM in PM2.5 simulations at the city scale also causes difficulties in evaluation of the control strategies. Therefore, our results suggest that the ensemble simulation is imperative to take into account the impact of the meteorological uncertainties on the haze prediction.
Climatology and interannual variability of dynamic variables in multiple reanalyses evaluated by the SPARC Reanalysis Intercomparison Project (S-RIP)
Authors: Long Craig S. , Fujiwara Masatomo , Davis Sean , Mitchell Daniel M. , Wright Corwin J. 
Published: December 2017

Abstract. Two of the most basic parameters generated from a reanalysis are temperature and winds. Temperatures in the reanalyses are derived from conventional (surface and balloon), aircraft, and satellite observations. Winds are observed by conventional systems, cloud tracked, and derived from height fields, which are in turn derived from the vertical temperature structure. In this paper we evaluate as part of the SPARC Reanalysis Intercomparison Project (S-RIP) the temperature and wind structure of all the recent and past reanalyses. This evaluation is mainly among the reanalyses themselves, but comparisons against independent observations, such as HIRDLS and COSMIC temperatures, are also presented. This evaluation uses monthly mean and 2.5° zonal mean data sets and spans the satellite era from 1979–2014. There is very good agreement in temperature seasonally and latitudinally among the more recent reanalyses (CFSR, MERRA, ERA-Interim, JRA-55, and MERRA-2) between the surface and 10 hPa. At lower pressures there is increased variance among these reanalyses that changes with season and latitude. This variance also changes during the time span of these reanalyses with greater variance during the TOVS period (1979–1998) and less variance afterward in the ATOVS period (1999–2014). There is a distinct change in the temperature structure in the middle and upper stratosphere during this transition from TOVS to ATOVS systems. Zonal winds are in greater agreement than temperatures and this agreement extends to lower pressures than the temperatures. Older reanalyses (NCEP/NCAR, NCEP/DOE, ERA-40, JRA-25) have larger temperature and zonal wind disagreement from the more recent reanalyses. All reanalyses to date have issues analysing the quasi-biennial oscillation (QBO) winds. Comparisons with Singapore QBO winds show disagreement in the amplitude of the westerly and easterly anomalies. The disagreement with Singapore winds improves with the transition from TOVS to ATOVS observations. Temperature bias characteristics determined via comparisons with a reanalysis ensemble mean (MERRA, ERA-Interim, JRA-55) are similarly observed when compared with Aura HIRDLS and Aura MLS observations. There is good agreement among the NOAA TLS, SSU1, and SSU2 Climate Data Records and layer mean temperatures from the more recent reanalyses. Caution is advised for using reanalysis temperatures for trend detection and anomalies from a long climatology period as the quality and character of reanalyses may have changed over time.
Total electron content responses to HILDCAAs and geomagnetic storms over South America

Published: December 2017

Abstract. Total electron content (TEC) is extensively used to monitor the ionospheric behavior under geomagnetically quiet and disturbed conditions. This subject is of greatest importance for space weather applications. Under disturbed conditions the two main sources of electric fields, which are responsible for changes in the plasma drifts and for current perturbations, are the short-lived prompt penetration electric fields (PPEFs) and the longer-lasting ionospheric disturbance dynamo (DD) electric fields. Both mechanisms modulate the TEC around the globe and the equatorial ionization anomaly (EIA) at low latitudes. In this work we computed vertical absolute TEC over the low latitude of South America. The analysis was performed considering HILDCAA (high-intensity, long-duration, continuous auroral electrojet (AE) activity) events and geomagnetic storms. The characteristics of storm-time TEC and HILDCAA-associated TEC will be presented and discussed. For both case studies presented in this work (March and August 2013) the HILDCAA event follows a geomagnetic storm, and then a global scenario of geomagnetic disturbances will be discussed. Solar wind parameters, geomagnetic indices, O ∕ N2 ratios retrieved by GUVI instrument onboard the TIMED satellite and TEC observations will be analyzed and discussed. Data from the RBMC/IBGE (Brazil) and IGS GNSS networks were used to calculate TEC over South America. We show that a HILDCAA event may generate larger TEC differences compared to the TEC observed during the main phase of the precedent geomagnetic storm; thus, a HILDCAA event may be more effective for ionospheric response in comparison to moderate geomagnetic storms, considering the seasonal conditions. During the August HILDCAA event, TEC enhancements from  ∼  25 to 80 % (compared to quiet time) were observed. These enhancements are much higher than the quiet-time variability observed in the ionosphere. We show that ionosphere is quite sensitive to solar wind forcing and considering the events studied here, this was the most important source of ionospheric responses. Furthermore, the most important source of TEC changes were the long-lasting PPEFs observed on August 2013, during the HILDCAA event. The importance of this study relies on the peculiarity of the region analyzed characterized by high declination angle and ionospheric gradients which are responsible for creating a complex response during disturbed periods.

Abstract. Dune development along highly dynamic land–sea boundaries is the result of interaction between vegetation and dune size with sedimentation and erosion processes. Disentangling the contribution of vegetation characteristics from that of dune size would improve predictions of nebkha dune development under a changing climate, but has proven difficult due to the scarcity of spatially continuous monitoring data. This study explored the contributions of vegetation and dune size to dune development for locations differing in shelter from the sea. We monitored a natural nebkha dune field of 8 ha, along the coast of the island Texel, the Netherlands, for 1 year using an unmanned aerial vehicle (UAV) with camera. After constructing a digital surface model and orthomosaic we derived for each dune (1) vegetation characteristics (species composition, vegetation density, and maximum vegetation height), (2) dune size (dune volume, area, and maximum height), (3) degree of shelter (proximity to other nebkha dunes and the sheltering by the foredune). Changes in dune volume over summer and winter were related to vegetation, dune size and degree of shelter. We found that a positive change in dune volume (dune growth) was linearly related to initial dune volume over summer but not over winter. Big dunes accumulated more sand than small dunes due to their larger surface area. Exposed dunes increased more in volume (0.81 % per dune per week) than sheltered dunes (0.2 % per dune per week) over summer, while the opposite occurred over winter. Vegetation characteristics did not significantly affect dune growth in summer, but did significantly affect dune growth in winter. Over winter, dunes dominated by Ammophila arenaria, a grass species with high vegetation density throughout the year, increased more in volume than dunes dominated by Elytrigia juncea, a grass species with lower vegetation density (0.43 vs. 0.42 (m3 m−3) week−1). The effect of species was irrespective of dune size or distance to the sea. Our results show that dune growth in summer is mainly determined by dune size, whereas in winter dune growth was determined by vegetation type. In our study area the growth of exposed dunes was likely restricted by storm erosion, whereas growth of sheltered dunes was restricted by sand supply. Our results can be used to improve models predicting coastal dune development.
A pore-size classification for peat bogs derived from unsaturated hydraulic properties
Authors: Weber Tobias Karl David , Iden Sascha Christian , Durner Wolfgang 
Published: December 2017

Abstract. In ombrotrophic peatlands, the moisture content of the acrotelm (vadoze zone) controls oxygen diffusion rates, redox state, and the turnover of organic matter. Thus, variably saturated flow processes determine whether peatlands act as sinks or sources of atmospheric carbon, and modelling these processes is crucial to assess effects of changed environmental conditions on the future development of these ecosystems. We show that the Richards equation can be used to accurately describe the moisture dynamics under evaporative conditions in variably saturated peat soil, encompassing the transition from the topmost living moss layer to the decomposed peat as part of the vadose zone. Soil hydraulic properties (SHP) were identified by inverse simulation of evaporation experiments on samples from the entire acrotelm. To obtain consistent descriptions of the observations, the traditional van Genuchten–Mualem model was extended to account for non-capillary water storage and flow. We found that the SHP of the uppermost moss layer reflect a pore-size distribution (PSD) that combines three distinct pore systems of the Sphagnum moss. For deeper samples, acrotelm pedogenesis changes the shape of the SHP due to the collapse of inter-plant pores and an infill with smaller particles. This leads to gradually more homogeneous and bi-modal PSDs with increasing depth, which in turn can serve as a proxy for increasing state of pedogenesis in peatlands. From this, we derive a nomenclature and size classification for the pore spaces of Sphagnum mosses and define inter-, intra-, and inner-plant pore spaces, with effective pore diameters of >  300, 300–30, and 30–10 µm, respectively.

Authors: Peltzer Karl , Pengpid Supa 
Published: December 2017

Introduction: There has been a global increase in illicit drug use among young people. The aim of this study was to estimate the prevalence of lifetime cannabis and amphetamine use, as well as to explore factors associated with substance use among adolescents in five Asian countries: Iraq, Kuwait, Malaysia, Mongolia, and Vietnam.Methods: 38,941 school children (mean age 15.4 years, SD=1.5) completed the cross-sectional Global School-Based Student Health Survey (GSHS). Topics covered in the questionnaire included cannabis and amphetamine use. Personal, parental, and environmental attributes were explored as predictors of cannabis and amphetamine use. Logistic regression was used to assess the contribution of potential predictors on lifetime cannabis and lifetime amphetamine use.Results: Overall, the prevalence of lifetime cannabis use was 0.9% and lifetime amphetamine use was 1.0% among research participants. Cannabis use was influenced by male gender (Kuwait, Mongolia), parental smoking habits (Kuwait, Iraq), and current cigarette smoking in all countries. Amphetamine use was associated with suicidal ideation (Kuwait, Malaysia, Vietnam), school truancy (Malaysia, Mongolia, Vietnam), being a victim of physical assault (Kuwait, Mongolia), bullying victimization (Iraq, Malaysia, Vietnam), as well as anxiety and current cigarette use in all countries. Conclusions: Our preliminary results show the importance of personal attributes such as mental distress and environmental stressors on lifetime cannabis and lifetime amphetamine use. Future prospective studies are needed to identify causal relationships among personal attributes, parental attributes, environmental stressors, and illicit substance use.

Published: December 2017

Este trabalho avaliou a atividade de manutenção mecânica de um feller buncher empregando a World Class Maintenance (WCM), que utiliza como premissa a manutenção preventiva, visando a redução dos custos de produção e melhor aproveitamento dos recursos disponíveis. O trabalho foi conduzido em plantios de Pinus taeda e Eucalyptus grandis de uma empresa florestal localizada no estado do Paraná, Brasil. A análise contemplou três períodos subsequentes de seis meses, sendo eles: implantação, amadurecimento e estabilização do modelo WCM. A avaliação foi realizada por meio da determinação dos índices de disponibilidade mecânica, consumo de óleo hidráulico e custos da manutenção. Os resultados mostraram que houve aumento na disponibilidade mecânica do equipamento de 1,75%. Para o consumo de óleo hidráulico, após o período de implantação, houve redução de 63%, reflexo este das manutenções preventivas realizadas durante as atividades. O custo de manutenção no modelo WCM apresentou redução de 14,4%, ocasionado pelo investimento de infraestrutura e treinamento de mecânicos e operadores. O modelo o WCM mostrou aplicabilidade na manutenção de equipamentos de corte florestal, com potencial de melhorias em relação à segurança operacional, capacidade produtiva e aumento da vida útil dos mesmos.

Published: December 2017

Uma das preocupações com o uso de lodo de esgoto no solo agrícola refere-se ao risco de poluição das águas subterrâneas causada pela lixiviação de nitrato, o que torna necessário mais pesquisas a esse respeito. Nesse contexto, o presente estudo objetivou avaliar o comportamento de três diferentes doses de biossólido oriundo da estação de tratamento de esgoto do Rio das Antas de Irati, Paraná. Foram misturados biossólido com Cambissolo nas dosagens de 2,5; 5,0; e 7,5%; em seguida, as amostras foram inseridas em colunas de PVC com o fundo vazado, que permitiram a captação da água percolada para realização das análises de nitrato. Os resultados comprovaram que doses de até 25 t.ha-1 não implicam em aumento significativo de nitrato no percolado, porém doses superiores a 80 t.ha-1 não devem ser aplicadas, pois, segundo o modelo de regressão encontrado, essa aplicação resultaria em doses nocivas de nitrato nas águas subterrâneas. Recomenda-se que em estudos futuros aspectos referentes à capacidade de troca catiônica e o teor de nitrogênio no solo sejam correlacionados com a concentração de nitrato percolado, uma vez que podem afetar significativamente o comportamento do íon no horizonte do solo.

Het gebruik van Big Data voor opsporingsdoeleinden: tussen Strafvordering en Wet politiegegevens
Het gebruik van grote hoeveelheden gegevens (Big Data) levert een steeds grotere bijdrage aan het succes van de opsporing. De toepassing van Big Data brengt echter ook (privacy)risico’s met zich mee. Door de gebrekkige samenhang tussen het Wetboek van Strafvordering en de Wet politiegegevens is het gebruik van Big Data momenteel niet goed gereguleerd. In dit artikel worden de belangrijkste risico’s voor de rechtsbescherming bij het gebruik van Big Data voor opsporingsdoeleinden besproken en wordt bekeken in hoeverre het huidige en toekomstige strafvorderlijke kader deze risico’s kan adresseren.

De rol van alternatieve handhaving in het mededingingstoezicht
In deze bijdrage worden enkele alternatieve handhavingsinstrumenten geanalyseerd zoals zij gebruikt worden door de Nederlandse Autoriteit Consument en Markt (ACM), de Britse Competition and Markets Authority (CMA) en de Franse Autorité de la Concurrence (de Autorité). Echter, hierbij ligt de focus niet op de individuele, juridische analyse van ieder handhavingsinstrument, maar op de relatie tussen handhavingsinstrumenten, onderliggende strategie, en toezichthouder. Het uiteindelijke doel van deze bijdrage is om te illustreren wat de gevolgen kunnen zijn van een brede toepassing van alternatieve handhavingsinstrumenten vanuit het perspectief van toezicht. Hierbij zullen er, met name in de concluderende paragrafen, conclusies worden getrokken die bruikbaar zijn voor het toepassen van alternatieve handhaving buiten het mededingingstoezicht.
