L’égalité, l’indépendance et l’union de fait : le choix de l’union de fait et du mariage au Québec et en Ontario de 1986 à 2011
Authors: Laplante Benoît , Fostik Ana 
Published: February 2018

Le débat qui a entouré la cause « Lola c. Éric » a renouvelé l’intérêt pour le rôle de l’indépendance économique de la conjointe et l’égalité des conjoints dans le couple dans le choix entre le mariage et l’union libre comme forme de vie conjugale. Il force également à réfléchir sur la signification sociale de la différence marquée entre le Québec et le reste du Canada dans l’usage de l’union de fait. Nous abordons la question en la reliant à la différence conceptuelle profonde qui sépare les systèmes de droit privé et d’État social des deux sociétés. Nous utilisons les microdonnées de l’échantillon de 20 % de la population qui a rempli le formulaire « long » du recensement canadien en 1986, 1996 et 2006 et de l’Enquête nationale auprès des ménages de 2011 en estimant, au moyen de la régression logistique, l’effet d’une série de caractéristiques sur la probabilité de vivre en union de fait plutôt que d’être mariée chez les femmes âgées de 20 à 49 ans qui vivent dans une union conjugale. Afin d’éviter de comparer des ensembles trop hétérogènes, nous comparons les francophones du Québec et les anglophones de l’Ontario. Les résultats montrent que dans les couples où la conjointe est active, l’indépendance économique de la conjointe et l’égalité économique des conjoints ont un effet significatif, mais secondaire sur la probabilité de vivre en union de fait. Au Québec, l’union de fait est la norme dans toutes les couches sociales pour tous les couples où la conjointe est active ; le mariage est plus fréquent dans les couples où la femme n’est pas active. En Ontario, vivre ensemble sans être mariés au-delà de 30 ans est essentiellement une affaire de classe sociale.
Combien d’enfants en double résidence ou en garde partagée ? Sources et mesures dans les contextes québécois et canadien
Authors: Pelletier David 
Published: February 2018

À la base de ce texte se trouve une question très simple : combien d’enfants partagent leur temps de façon plus ou moins égale entre la résidence de leur mère et celle de leur père à la suite de la séparation de ceux-ci ? Après une description des nombreux enjeux liés à la mesure des arrangements résidentiels des enfants, une analyse critique des différentes sources de données disponibles aux niveaux québécois et canadien permet de constater le caractère fragmentaire de nos connaissances actuelles sur le sujet. Au final, la réponse apportée reste équivoque. D’un point de vue relatif, on peut affirmer sans trop de risques de se tromper que le nombre d’enfants en double résidence a augmenté rapidement au cours des deux dernières décennies, et davantage au Québec que dans le reste du Canada. Concernant les niveaux absolus, cependant, beaucoup d’incertitude demeure puisque les chiffres produits par les diverses sources concordent rarement. L’intégration de données d’enquête et de données administratives sera probablement nécessaire afin d’apporter une réponse plus solide.
« Les ploucs, les bourgeoises et les filles1 comme nous. » Ethnosociographie d’un cours de yoga démocratique
Authors: Madec Annick 
Published: February 2018

Par la participation observante durant plusieurs années de ce qui se dit et se fait dans des cours de yoga, cet article montre les rapports sociaux construits par des femmes de différentes classes sociales qui pratiquent une même activité, mais ne partagent pas les mêmes valeurs. Examiner comment égalité et coopération sont mobilisées dans les manières d’être d’élèves yogis permet de montrer que ces valeurs restent au coeur des cultures populaires et de distinguer deux groupes : les mutualistes, héritières de ces cultures, qui assument leurs origines sociales, et les compétitrices, individualistes, qui plagient les catégories supérieures. La transmission des éthos de classe n’opère pas systématiquement terme à terme.
Relier l’induction et la critique en formation et en recherche : un parti-pris issu de la théorie et de la pratique
Authors: Berryman Tom 
Published: February 2018

Prenant appui sur des pratiques de formation et de recherche en contexte universitaire, cet article constitue une sorte d’invitation à relier l’induction et la critique dans ces deux champs de pratique. La première partie du texte est centrée sur la formation alors que la deuxième est centrée sur la recherche. Chaque partie possède une structure similaire. Elle débute de manière inductive avec un exemple de pratique avant de se tourner vers des considérations plus théoriques. Inspirée notamment parL’imagination sociologiquede Charles Wright Mills originalement publié en 1959, la thèse développée ici est celle d’une grande actualité des propos de Mills qui insistait pour articuler biographie, histoire et société en résistant à la « suprême théorie » et à « l’empiricité libérale ». Le contexte actuel de la vie universitaire invite à actualiser de tels regards tant sur les pratiques de formation que sur les pratiques de recherche.
MTE et psychanalyse : analyse en tandem et pensées associatives enracinées
Authors: Castonguay Laurent , Noël Raphaële 
Published: February 2018

Cet article présente une conceptualisation de paramètres méthodologiques de la thèse de spécialisation du premier auteur. La procédure d’analyse des données de même que les outils réflexifs employés par les deux chercheurs sont ici mis en perspective avec la pensée psychanalyse et la MTE. De cette pratique réflexive émergent deux notions clés : une attitude de pensée associative comme enrichissement et voie de passage vers une analyse conceptualisante et la pratique d’une analyse collaborative des données dans la perspective du recours complémentaire à deux subjectivités.
Seasonal variation in the abundance and distribution ofAnomalocardia flexuosa(Mollusca, Bivalvia, Veneridae) in an estuarine intertidal plain
Authors: Silva-Cavalcanti Jacqueline S. , Costa Monica F. , Alves Luis H.B. 
Published: February 2018

Spatial and temporal density and biomass of the infaunal molluskAnomalocardia flexuosa(Linnaeus, 1767) evaluated a tidal plain at Goiana estuary (Northeast Brazil). Three hundred and sixty core samples were taken during an annual cycle from three intertidal habitats (A, B and C). Shell ranged from 2.20 to 28.48 mm (15.08 ± 4.08 mm). Recruitment occurred more intensely from January to March. Total (0–1,129 g m−2) differed seasons (rainy and dry), with highest values in the early rainy season (221.0 ± 231.44 g m−2); and lowest values in the late dry season (57.34 ± 97 g m−2). The lowest occurred during the late rainy (319 ± 259 ind m−2) and early dry (496 ± 607 ind m−2) seasons. Extreme environmental situations (e.g., river flow, salinity and water temperature) at the end of each season also affected density ranges (late dry: 0–5,798 ind m−2; late rainy: 0–1,170 ind m−2).A. flexuosain the Goiana estuary presented a dominance of juvenile individuals (shell length < 20 mm), with high biomass main the recruitment period. Average shell length, density and biomass values suggest overfishing of the stock unit.A. flexuosais an important food and income resource along its whole distribution range. The species was previously also known asAnomalocardia brasiliana(Gmelin, 1791).

AbstractThe present investigation reports for the first time seasonal and solar activity variations of F3 and StF4 layers at the low‐latitude station of Tucumán (26.9°S, 65.4°W; dip latitude 13.9°S), Argentina, by considering ionograms recorded from 2007 to 2015 by an Advanced Ionospheric Sounder‐Istituto Nazionale di Geofisica e Vulcanologia (AIS‐INGV) digital ionosonde. Occurrences of F3 and StF4 layers are found to be higher during summer months, while they are almost nil in winter. Moreover, occurrences of F3 and StF4 layers show a solar activity dependence with higher values during high solar activity. The solar activity dependence of F3 over Tucumán is similar to that reported earlier for the low‐latitude station of São José dos Campos, Brazil (dip latitude 14.1°S), but different than that reported for the near‐equatorial station of Palmas (dip latitude 6.6°S), Brazil. On the other hand, the solar cycle dependence of StF4 layer is consistent with the one obtained at Palmas. This highlights the complex nature of electrodynamics characterizing the ionosphere from the magnetic equatorial to low latitudes. Moreover, as shown in previous studies, the StF4 layer is always preceded and followed by the F3 layer, and it shows a shorter lifetime than that of the F3 layer. During the considered period, 1812 days were analyzed and the F3 layer was found in 370 days (20.4%), while the StF4 layer was found in 41 days (2.3%). This means that the StF4 stratification is seen during 11% of F3 layer days.

AbstractThe production and transport of plasma mass are essential processes in the dynamics of planetary magnetospheres. At Jupiter, it is hypothesized that Io's volcanic plasma carried out of the plasma torus is transported radially outward in the rotating magnetosphere and is recurrently ejected as plasmoid via tail reconnection. The plasmoid ejection is likely associated with particle energization, radial plasma flow, and transient auroral emissions. However, it has not been demonstrated that plasmoid ejection is sensitive to mass loading because of the lack of simultaneous observations of both processes. We report the response of plasmoid ejection to mass loading during large volcanic eruptions at Io in 2015. Response of the transient aurora to the mass loading rate was investigated based on a combination of Hisaki satellite monitoring and a newly developed analytic model. We found that the transient aurora frequently recurred at a 2–6 day period in response to a mass loading increase from 0.3 to 0.5 t/s. In general, the recurrence of the transient aurora was not significantly correlated with the solar wind, although there was an exceptional event with a maximum emission power of ~10 TW after the solar wind shock arrival. The recurrence of plasmoid ejection requires the precondition that an amount comparable to the total mass of magnetosphere, ~1.5 Mt, is accumulated in the magnetosphere. A plasmoid mass of more than 0.1 Mt is necessary in case that the plasmoid ejection is the only process for mass release.
High Frequency Near‐Field Ground Motion Excited by Strike‐Slip Step Overs
Authors: Hu Feng , Wen Jian , Chen Xiaofei 
Published: February 2018

AbstractWe performed dynamic rupture simulations on step overs with 1–2 km step widths and present their corresponding horizontal peak ground velocity distributions in the near field within different frequency ranges. The rupture speeds on fault segments are determinant in controlling the near‐field ground motion. A Mach wave impact area at the free surface, which can be inferred from the distribution of the ratio of the maximum fault‐strike particle velocity to the maximum fault‐normal particle velocity, is generated in the near field with sustained supershear ruptures on fault segments, and the Mach wave impact area cannot be detected with unsustained supershear ruptures alone. Sub‐Rayleigh ruptures produce stronger ground motions beyond the end of fault segments. The existence of a low‐velocity layer close to the free surface generates large amounts of high‐frequency seismic radiation at step over discontinuities. For near‐vertical step overs, normal stress perturbations on the primary fault caused by dipping structures affect the rupture speed transition, which further determines the distribution of the near‐field ground motion. The presence of an extensional linking fault enhances the near‐field ground motion in the extensional regime. This work helps us understand the characteristics of high‐frequency seismic radiation in the vicinities of step overs and provides useful insights for interpreting the rupture speed distributions derived from the characteristics of near‐field ground motion.

AbstractMany weather forecast and climate models simulate warm surface air temperature (T2m) biases over midlatitude continents during the summertime, especially over the Great Plains. We present here one of a series of papers from a multimodel intercomparison project (CAUSES: Cloud Above the United States and Errors at the Surface), which aims to evaluate the role of cloud, radiation, and precipitation biases in contributing to the T2m bias using a short‐term hindcast approach during the spring and summer of 2011. Observations are mainly from the Atmospheric Radiation Measurement Southern Great Plains sites. The present study examines the contributions of surface energy budget errors. All participating models simulate too much net shortwave and longwave fluxes at the surface but with no consistent mean bias sign in turbulent fluxes over the Central United States and Southern Great Plains. Nevertheless, biases in the net shortwave and downward longwave fluxes as well as surface evaporative fraction (EF) are contributors to T2m bias. Radiation biases are largely affected by cloud simulations, while EF bias is largely affected by soil moisture modulated by seasonal accumulated precipitation and evaporation. An approximate equation based upon the surface energy budget is derived to further quantify the magnitudes of radiation and EF contributions to T2m bias. Our analysis ascribes that a large EF underestimate is the dominant source of error in all models with a large positive temperature bias, whereas an EF overestimate compensates for an excess of absorbed shortwave radiation in nearly all the models with the smallest temperature bias.
Unraveling the History of Meridiani Planum, Mars: New Chemical Clues From the Rim of Endeavour Crater
Authors: Fraeman Abigail A. 
Published: February 2018

AbstractMittlefehldt et al. (2018, https://doi.org/10.1002/2017JE005474) synthesize Alpha Particle X‐Ray Spectrometer chemical measurements along more than 4.5 km of Endeavour crater's rim. Their analyses clarify details of Endeavour's geologic history, including evidence for three to four distinct episodes of aqueous alteration. Fracture‐driven aqueous systems and Mn mobility are particularly important both here and at Curiosity's landing site on the opposite side of the planet. The detailed documentation of Alpha Particle X‐Ray Spectrometer data products within this paper will be a key reference for researchers who want to perform future work on questions related to Mars aqueous geochemistry, impact processes, and Martian crustal and atmospheric evolution.

AbstractThe advent of adaptive manufacturing techniques supports the vision of cell‐instructive materials that mimic biological tissues. 3D jet writing, a modified electrospinning process reported herein, yields 3D structures with unprecedented precision and resolution offering customizable pore geometries and scalability to over tens of centimeters. These scaffolds support the 3D expansion and differentiation of human mesenchymal stem cells in vitro. Implantation of these constructs leads to the healing of critical bone defects in vivo without exogenous growth factors. When applied as a metastatic target site in mice, circulating cancer cells home in to the osteogenic environment simulated on 3D jet writing scaffolds, despite implantation in an anatomically abnormal site. Through 3D jet writing, the formation of tessellated microtissues is demonstrated, which serve as a versatile 3D cell culture platform in a range of biomedical applications including regenerative medicine, cancer biology, and stem cell biotechnology.
Vanadium Dioxide Integrated Metasurfaces with Switchable Functionalities at Terahertz Frequencies
Authors: Ding Fei , Zhong Shuomin , Bozhevolnyi Sergey I. 
Published: February 2018

AbstractIntegration of switchable and diversified functionalities into a single metasurface has become an emerging research area that requires dealing with formidable challenges, especially for terahertz (THz) frequencies. Here, polarization‐insensitive and switchable THz metasurfaces are proposed with diversified functionalities that exploit insulator‐to‐metal transition in vanadium dioxide (VO2). The simulations demonstrate that the designed metasurface can be switched from a broadband absorber to a reflecting broadband halfwave plate (HWP). At room temperature, the metasurface efficiently absorbs normally incident waves ranging from 0.562 to 1.232 THz with the total absorption exceeding 90%. Once the temperature is high enough and VO2 is in its fully metallic state, the metasurface becomes a broadband HWP reflecting over 60% of the incident power with the linear polarization conversion efficiency exceeding 95% within the bandwidth of 0.49 THz. Moreover, the broadband performance is sustained over a wide range of incident angles. To extend the functionalities, metasurface supercell made of several VO2 antennas is integrated, consequently achieving directional polarization conversion when VO2 is in its fully metallic state while maintaining broadband absorption at insulating state. The proposed switchable metasurfaces are expected to enable advanced research and smart applications related to other tunable and diverse functionalities at THz frequencies.

AbstractObjectiveThe objective was to determine whether brief, Web‐based instruction several weeks prior to tourniquet application improves layperson success compared to utilizing just‐in‐time (JiT) instructions alone.BackgroundStop the Bleed is a campaign to educate laypeople to stop life‐threatening hemorrhage. It is based on U.S. military experience with lifesaving tourniquet use. While previous research shows simple JiT instructions boost laypeople's success with tourniquet application, the optimal approach to educate the public is not yet known.MethodsThis is a prospective, nonblinded, randomized study. Layperson participants from the Washington, DC, area were randomized into: 1) an experimental group that received preexposure education using a website and 2) a control group that did not receive preexposure education. Both groups received JiT instructions. The primary outcome was the proportion of subjects that successfully applied a tourniquet to a simulated amputation. Secondary outcomes included mean time to application, mean placement position, ability to distinguish bleeding requiring a tourniquet from bleeding requiring direct pressure only, and self‐reported comfort and willingness to apply a tourniquet.ResultsParticipants in the preexposure group applied tourniquets successfully 75% of the time compared to 50% success for participants with JiT alone (p < 0.05, risk ratio = 1.48, 95% confidence interval = 1.21–1.82). Participants place tourniquets in a timely fashion, are willing to use them, and can recognize wounds requiring tourniquets.ConclusionsBrief, Web‐based training, combined with JiT education, may help as many as 75% of laypeople properly apply a tourniquet. These findings suggest that this approach may help teach the public to Stop the Bleed.
Recent Progress in Using Pyrene‐4,5‐diketones and Pyrene‐4,5,9,10‐tetraketones as Building Blocks to Construct Large Acenes and Heteroacenes
Authors: Jin Pengcheng , Song Tingting , Xiao Jinchong , Zhang Qichun 
Published: February 2018

AbstractAcenes, usually defined as segments of “graphene”, consist of linearly annulated benzene rings, and have attracted considerable interest in both theoretical research and practical applications. However, these compounds generally have undesirable features such as poor solubility, easy oxidation and photodimerization. Thus, scientists have to invest much effort to address these problems and experimentally achieve the desired electronic properties to meet various demands. Herein, we summarize recent progress in the synthesis of pyrene‐functionalized acenes and heteroacenes through the use of pyrene diketone and pyrene tetraketone building blocks. Moreover, the physical properties and applications of these semiconductors in organic semiconductor devices are also described.
