Basic Dimensions of Resilient Coping in Paramedics and Dispatchers
Authors: Bilsker Dan , Gilbert Merv , Alden Lynn , Sochting Ingrid , Khalis Adri 
Published: June 2019

Introduction Paramedics and dispatchers are exposed to high levels of stress and consequent psychological injury. Resilience training enhances the capacity to cope with stress and be resilient. It is widely recommended that resilience training be customised to specific occupational groups, but there is no established method for achieving such customisation. Exploratory factor analysis was used to identify dimensions underlying resilient coping in paramedics and dispatchers. The objective was to provide a basis for customised resilience training in this population. Methods The Resilient Coping Survey (RCS) was developed on the basis of interviews with paramedics and dispatchers as well as scoping review to identify coping items relevant to this occupational group. The RCS included scales of coping (Resilience at Work and the Self-Compassion Scale – Short Form), a scale of self-perceived resilience (the Brief Resilience Scale) and a set of items reflecting coping skills specific to paramedic service work. The survey was administered to paramedics and dispatchers in British Columbia, Canada. Results 703 paramedics and dispatchers responded to the survey. Analysis of the survey data identified five resilient coping factors: balance, self-acceptance, trusted social support, meaningful work and physical self-care. Each of these factors predicted resilience. No difference was found overall in resilience across gender; but only for male workers did resilience fall steadily with years of service. Conclusion Resilience training for paramedics and dispatchers would appropriately target the five resilient coping factors and be delivered throughout the paramedic service career.
Sur la structure du succinonitrile dans sa phase plastique
Authors: Fontaine Hubert , Bée Marc 
Published: June 2019

Starting from the possible equilibrium positions of the different succinonitrile isomers in the cubic cell derived by means of the polarisation of the Raman lines, we have been able to determine a mean molecular configuration compatible with the symetry of the crystal and this enables us to account for the structure factors observed when introducing anisotropic Debye-Waller factors. We have been able to derive, in a precise way, the space group of succinonitrile in the plastic phase, I[m3m], and the equilibrium positions of the molecule. The anisotropic Debye-Waller factors are compatible with the molecular reorientation movements and characterize satisfactorily the strong anharmonicity of the crystal.
The linear expansion coefficient of succinonitrile in the plastic phase is 1.85 x 10⁻⁴ °C⁻¹, similar to that of liquids.
Étude de la coloration bleue de quelques fluorites naturelles
Authors: Calas Georges 
Published: June 2019

Optical absorption spectra of blue fluorites from three localities (Valzergues and Chavaniac, France ; Djebel el Kohol, Tunisia) show that in these cases the blue colour is due to a complex colour centre associated with yttrium. Thermal bleaching studies indicate a fast phenomena (half of the colour centres disappearing after 200-450 years at 0° C). Bleaching is reversible, indicating that this colour exists because of a permanent irradiation due to radioactive elements incorporated in the crystals during growth.
Évolution des minéraux argileux dans les sédiments paléogènes du Bassin de Mormoiron (Vaucluse)
Authors: Triat Jean-Marie , Trauth Norbert 
Published: June 2019

L'étude minéralogique des terrains paléogènes du bassin de Mormoiron (Vaucluse, France) a été entreprise à partir de 800 échantillons répartis en neuf coupes et deux sondages. Le gisement d'attapulgite de Mormoiron décrit par J. de Lapparent a été réétudié.
Les variétés de minéraux argileux sont associées à des faciès de roches sédimentaires différentes :
faciès continental → argile alumineuse (kaolinite, smectite Al),
faciès évaporitique → argile magnésienne (stévensite, sépiolite),
faciès intermédiaire → argile alumino-magnésienne (attapulgite, saponite).
Le bassin de Mormoiron apparaît au Paléogène comme un bassin où le chimisme l'emporte sur l'héritage, permettant la formation de minéraux argileux en équilibre avec les différents milieux de sédimentation.

Authors: Meyer Paulette 
Published: June 2019

The lattice and the unit cell dimensions of two unstable phases at ordinary temperature have been determined from unoriented crystals, using unscreened Weissenberg diagrams.
For KNO₃ we find a monoclinic c-centred lattice. The unit cell dimensions are : a = 6.8 Å, b = 5.6 Å, c = 4.3 Å, β = 100°.
For NaClO₃ the lattice is also monoclinic c-centred : a = 13.3 Å, b = 10.8 Å, c = 12.5 Å, β = 100°.

This apparently stoichiometric compound belongs to a solid solution series, the limits of which are Sc₁.₈Er₃.₂S₇ and Sc₂.₁Er₂.₉S₇. It has the same crystal structure as Y₅S₇, and the its cell parameters are : a = 12.29 Å ; b = 3.741 Å ; c = 11.26 Å and β = 104.9°.
The powder pattern of the compound is given as for the other ternary sulfides of the same type, the two metals have a disordered arrangement on the octahedral sites. From a single-crystal structural study (R = 0.056) the proportions of atoms on the sites were obtained.
Évolution thermique des bauxites. Comparaison des résultats obtenus par analyse thermique différentielle et par dilatométrie
Authors: Murat Michel 
Published: June 2019

La décomposition thermique des hydrates d'alumine à la pression atmosphérique se traduit, en A. T. D., par des effets systématiquement endothermiques. En dilatométrie, ces réactions se manifestent — soit par des contractions importantes (cas de l'hydrargillite) ou d'intensité faible (cas du diaspore) — soit par des dilatations marquées (cas de la boehmite). Ces phénomènes se retrouvent lorsque l'on soumet les bauxites aux deux techniques d'analyse envisagées. L'étude d'une série d'échantillons d'origines diverses et de compositions minéralogiques très différentes permet de montrer l'intérêt que peut présenter l'enregistrement des variations dimensionnelles au cours de l'évolution thermique d'éprouvettes obtenues par compactage des matériaux pulvérulents. La détection de certains constituants (boehmite) ou de minéraux étrangers (quartz) est beaucoup plus facile en dilatométrie qu'en A. T. D. Par contre l'enregistrement des effets thermiques est mieux adaptés à la détection de l'hydrargillite ou de la kaolinite en présence de boehmite. Les deux techniques apportent donc des renseignements analytiques tout à fait complémentaires.
De part et d’autre du Cher : du parterre de Diane aux premiers jardins de Catherine de Médicis à Chenonceau
Authors: Faisant Étienne 
Published: June 2019

An den Ufern des Flusses Cher. Vom Gartenparterre der Diana von Poitiers zu den Gärten der Katharina von Medici
Seit der Veröffentlichung der Rechnungsbücher durch den Abbé Chevalier im Jahre 1864 ist der Garten neben dem Schloss Chenonceau, den Diana von Poitiers von 1551 bis 1556 anlegen ließ, gut dokumentiert. Eine neue Studie bestätigt, dass der Gelehrte in seiner Edition der im Schloss aufbewahrten Rechnungsbücher kein wichtiges Detail übergangen hatte. Dagegen sind die Archive nicht sehr ergiebig, was die am anderen Ufer des Cher für Katharina von Medici angelegten Gärten betrifft, nachdem diese Ende 1559 das Anwesen erworben hatte. Neu entdeckte und im Anhang veröffentlichte Fragmente von Rechnungen liefern nun den Beweis, dass dort 1561-1562 Arbeiten im Gange waren. Diese neuen Einblicke erlauben folglich, den Entstehungszeitpunkt der Planzeichnungen von Du Cerceau zeitlich einzugrenzen, vor allem aber die oft wiederholte Zuschreibung der Gärten zugunsten von Bernard Palissy auszuschließen.

Radial Velocities, Space Motions, and Nearby Young Moving Group Memberships of Eleven Candidate Young Brown Dwarfs∗

Published: June 2019

Abstract
We present new radial velocity (RV) measurements for 11 candidate young very-low-mass stars and brown dwarfs, with spectral types from M7 to L7. Candidate young objects were identified by features indicative of low surface gravity in their optical and/or near-infrared spectra. RV measurements are derived from high-resolution (R =λ/Δλ = 20,000) J-band spectra taken with NIRSPEC at the Keck Observatory. We combine RVs with proper motions and trigonometric distances to calculate three-dimensional space positions and motions and to evaluate membership probabilities for nearby young moving groups (NYMGs). We propose 2MASS J00452143+1634446 (L2β, J = 13.06) as an RV standard given the precision and stability of measurements from three different studies. We test the precision and accuracy of our RV measurements as a function of spectral type of the comparison object, finding that RV results are essentially indistinguishable even with differences of ±5 spectral subtypes. We also investigate the strengths of gravity-sensitive K i lines at 1.24–1.25 μm and evaluate their consistency with other age indicators. We confirm or reconfirm four brown dwarf members of NYMGs—2MASS J00452143+1634446, WISE J00470038+6803543, 2MASS J011747483403258, and 2MASS J193555952846343—and their previous age estimates. We identify one new brown dwarf member of the Carina-Near moving group, 2M2154−10. The remaining objects do not appear to be members of any known NYMGs, despite their spectral signatures of youth. These results add to the growing number of very-low-mass objects exhibiting signatures of youth that lack likely membership in a known NYMG, thereby compounding the mystery regarding local, low-density star formation.
Open and Closed Magnetic Configurations of Twisted Flux Tubes
Authors: Sen Samrat , Mangalam A. 
Published: June 2019

Abstract
We construct two classes of magnetohydrostatic (MHS) equilibria for an axisymmetric vertical flux tube spanning from the photosphere to the lower part of the transition region within a realistic stratified solar atmosphere subject to solar gravity. We assume a general quadratic expression of the magnetic flux function for the gas pressure and poloidal current and solve the Grad–Shafranov equation analytically. The solution is a combination of a homogeneous and a particular part where the former is separable by a Coulomb function in r and exponential in z, while the particular part is an open configuration that has no z dependence. We also present another open field solution by using a self-similar formulation with two different profile functions and incorporating stratified solar gravity to maintain the magnetohydrostatic equilibria, which is a modification of earlier self-similar models with a twist. We study the admitted parameter space that is consistent with the conditions in the solar atmosphere and derive the magnetic and thermodynamic structures inside the flux tube that are reasonably consistent with the photospheric magnetic bright points for both open and closed field Coulomb function and self-similar models as estimated from observations and simulations. The obtained open and closed field flux tube solutions can be used as the background conditions for the numerical simulations for the study of the wave propagation through the flux tubes. The solutions can also be used to construct realistic magnetic canopies.
Special Relativistic Magnetohydrodynamics with Gravitation
Authors: Noh Hyerim , Hwang Jai-chan , Bucher Martin 
Published: June 2019

Abstract
We present a fully nonlinear and exact perturbation formulation of Einstein’s gravity with a general fluid and ideal magnetohydrodynamics (MHD) without imposing the slicing (temporal gauge) condition. Using this formulation, we derive equations of special relativistic (SR) MHD in the presence of weak gravitation. The equations are consistently derived in the limits of weak gravity and action-at-a-distance in the maximal slicing. We show that in this approximation the relativistic nature of gravity does not affect the SR MHD dynamics, but SR effects manifest themselves in the metric, and thus in gravitational lensing. Our formulation can account for strong SR effects, which might dominate over the Newtonian lensing potentials. Neglecting these SR effects may lead to an overestimation of lensing masses.
Photometric Redshift Calibration Requirements for WFIRST Weak-lensing Cosmology: Predictions from CANDELS

Published: June 2019

Abstract
In order for the Wide-Field Infrared Survey Telescope (WFIRST) and other stage IV dark energy experiments (e.g., Large Synoptic Survey Telescope, LSST; and Euclid) to infer cosmological parameters not limited by systematic errors, accurate redshift measurements are needed. This accuracy can be met by using spectroscopic subsamples to calibrate the photometric redshifts for the full sample. In this work, we find the minimal number of spectra required for the WFIRST weak-lensing redshift calibration by employing the Self-Organizing Map (SOM) spectroscopic sampling technique. We use galaxies from the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) to build the LSST+WFIRST lensing analog sample of ∼36,000 objects and to train the LSST+WFIRST SOM. We find that 26% of the WFIRST lensing sample consists of sources fainter than the Euclid depth in the optical, 91% of which live in color cells already occupied by brighter galaxies. We demonstrate the similarity between faint and bright galaxies as well as the feasibility of redshift measurements at different brightness levels. Our results suggest that the spectroscopic sample acquired for calibration to the Euclid depth is sufficient for calibrating the majority of the WFIRST color space. For the spectroscopic sample to fully represent the synthetic color space of WFIRST, we recommend obtaining additional spectroscopy of ∼0.2–1.2k new sources in cells occupied by mostly faint galaxies. We argue that either the small area of the CANDELS fields and the small overall sample size or the large photometric errors might be the reason for no/fewer bright galaxies mapped to these cells. Acquiring the spectra of these sources will confirm the above findings and will enable the comprehensive calibration of the WFIRST color–redshift relation.
The Optical to Mid-infrared Extinction Law Based on the APOGEE, Gaia DR2, Pan-STARRS1, SDSS, APASS, 2MASS, and WISE Surveys
Authors: Wang Shu , Chen Xiaodian 
Published: June 2019

Abstract
A precise interstellar dust extinction law is critically important to interpret observations. There are two indicators of extinction: the color excess ratio (CER) and the relative extinction. Compared to the CER, the wavelength-dependent relative extinction is more challenging to be determined. In this work, we combine spectroscopic, astrometric, and photometric data to derive high-precision CERs and relative extinction from optical to mid-infrared (IR) bands. A group of 61,111 red clump (RC) stars are selected as tracers by stellar parameters from the Apache Point Observatory Galaxy Evolution Experiment survey. The multiband photometric data are collected from Gaia, APASS, Sloan Digital Sky Survey, Pan-STARRS1, Two Micron All Sky Survey, and Wide-field Infrared Survey Explorer surveys. For the first time, we calibrate the curvature of CERs in determining CERs E(λ − G

V = 3.1 curve, together with the near-IR (NIR) power-law index α = 2.07 ± 0.03. The relative extinction values of the Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST) NIR bandpasses are predicted in 2.5% precision. As the observed reddening/extinction tracks are curved, the curvature correction needs to be considered when applying extinction correction.
Realism and Presence in Simulation: Nursing Student Perceptions and Learning Outcomes
Authors: MacLean Sharon , Geddes Fiona , Kelly Michelle , Della Phillip 
Published: June 2019

Background:Research examining how perceived realism and presence affects participants' learning experiences and outcomes is limited.Method:A convergent mixed-methods design was used, with quantitative data assigned as the primary method. After engaging in a communication training simulation, 141 undergraduate nursing students completed the Concept of Presence, Simulation Design, and the Quality of Discharge Teaching scales. A subsample of 12 participants were interviewed to provide qualitative data, as the secondary method, on their learning experience. Hierarchical multiple regression analysis was performed on the quantitative data and thematic analysis for qualitative data.Results:Differences in participants' perceived realism and level of presence were not affected by the communication-based learning interventions. A positive, fully mediated relationship between realism, presence, and learning outcomes in discharge communication skills was found. The quality of the simulation experience gave participants the opportunity to reflect on their knowledge and capacity to transfer skills into clinical practice.Conclusion:The convergence of findings supports the theory that perceived realism and presence positively affected learning outcomes.[J Nurs Educ.2019;58(6):330–338.]
