Sound Practice: Evaluating DACS Compliance in Archival Description of Music Recordings
Authors: Surles Elizabeth 
Published: May 2019

Standardization of descriptive practice supports improved access to archival collections with sound recordings of music. However, description of music sound recordings is complicated because of the unique characteristics of both music and sound recordings. Unfortunately, the standard for archival description in the United States, Describing Archives: A Content Standard (DACS), does not supply specific rules for music sound recordings, although it does recommend that archivists consult The International Association of Sound and Audiovisual Archives (IASA) Cataloguing Rules: A Manual for Description of Sound Recordings and Related Audiovisual Media for guidance. Given the wide range of descriptive options available via this recommendation, this study evaluates the extent to which finding aids for music collections with sound recordings successfully adhere to DACS, both in the application of IASA’s Rules as well as overall compliance with the standard in description of music sound recordings. Using document analysis methodology, this study finds low compliance with DACS and shows that finding aids commonly fail to apply IASA’s Rules correctly in description of music sound recordings. More research is needed to determine the reason(s) for this noncompliance. Possible solutions to improve standardization could include updating and clarifying the instructions in DACS, or using a different standard that provides specific instructions for description of archival sound recordings.
Theoretical Reflectance Spectra of Earth-like Planets through Their Evolutions: Impact of Clouds on the Detectability of Oxygen, Water, and Methane with Future Direct Imaging Missions
Authors: Kawashima Yui , Rugheimer Sarah 
Published: May 2019

Abstract
In the near-future, atmospheric characterization of Earth-like planets in the habitable zone will become possible via reflectance spectroscopy with future telescopes such as the proposed LUVOIR and HabEx missions. While previous studies have considered the effect of clouds on the reflectance spectra of Earth-like planets, the molecular detectability considering a wide range of cloud properties has not been previously explored in detail. In this study, we explore the effect of cloud altitude and coverage on the reflectance spectra of Earth-like planets at different geological epochs and examine the detectability of

, and CH4 with test parameters for the future mission concept, LUVOIR, using a coronagraph noise simulator previously designed for WFIRST-AFTA. Considering an Earth-like planet located at 5 pc away, we have found that for the proposed LUVOIR telescope, the detection of the O2
A-band feature (0.76 μm) will take approximately 100, 30, and 10 hr for the majority of the cloud parameter space modeled for the atmospheres with 10%, 50%, and 100% of modern Earth O2 abundances, respectively. In particular, for the case of ≳50% of modern Earth O2 abundance, the feature will be detectable with an integration time ≲10 hr as long as there are lower-altitude (≲8 km) clouds with a global coverage of ≳20%. For the 1% of the modern Earth O2 abundance case, however, it will take more than 100 hr for all the cloud parameters we modeled.
Conversion Measure of Faraday Rotation–Conversion with Application to Fast Radio Bursts
Authors: Gruzinov Andrei , Levin Yuri 
Published: May 2019

Abstract
Faraday rotation–conversion is the simultaneous rotation of all three Stokes polarization parameters, Q, U, and V, as an electromagnetic wave propagates through a magnetized plasma. In this regime, the Faraday plasma screen is characterized by more than just a rotation measure. We define the conversion measure that characterizes the wavelength-dependent conversion between the linear and circular polarization. In a cold plasma, the conversion occurs at the localized regions along the wave’s path, where the large-scale magnetic field is perpendicular to the propagation direction. We show that the number of these regions along the line of sight through the screen, and their individual contributions to the conversion measure, can be inferred from the polarization measurements. We argue that the simultaneous measurement of wavelength-dependent linear and circular polarization might give an important insight into the magnetic-field geometry of the Faraday screen in FRB 121102 and other repeating fast radio bursts.
Spectral Properties and Abundances of Suprathermal Heavy Ions in Compression Regions near 1 au
Authors: Filwett R. J. , Desai M. I. , Ebert R. W. , Dayeh M. A. 
Published: May 2019

Abstract
We have analyzed spectral properties and abundances of ∼0.02–3.0 MeV nucleon−1 suprathermal (ST) H–Fe ions in 41 stream interaction regions (SIRs) near 1 au observed by Wind and ACE spacecraft from 1995 January through 2008 December. We find that, (i) the event-averaged spectral index is γ ∼ 2.44, with a standard deviation (σ) of 0.67, (ii) γ’s are poorly correlated with the magnetic compression ratios, and 17% of the events group around γ ∼ 1.5, (iii) γ’s for both O and Fe at ∼0.02–0.09 MeV nucleon−1 and 0.09–0.3 MeV nucleon−1 are correlated, but do not exhibit any systematic steepening or flattening as a function of energy, (iv) the ST heavy ion abundance ratios remain constant with increasing energy, implying that the spectral rollovers, defined by the e-folding energy E
0, are independent of the ion’s mass per charge (M/Q), and (v) SIR ST abundances are similar to the corresponding solar wind values, and do not exhibit any systematic behavior when plotted versus the ion’s M/Q or first ionization potential. The above results pose challenges for (1) particle acceleration models that invoke either a corotating interaction region or SIR shocks between ∼3 and 5 au, (2) particle transport models that predict M/Q-dependent spectral rollovers due to interplanetary turbulence effects, and (3) the notion that SIR ST ions originate directly from the bulk solar wind. Instead, we suggest that the SIR ST ions are accelerated out of a pool of material that includes particles accelerated in solar energetic particle events and processed or heated solar wind ions.
The Influence of Host Star Spectral Type on Ultra-hot Jupiter Atmospheres
Authors: Lothringer Joshua D. , Barman Travis 
Published: May 2019

Abstract
Ultra-hot Jupiters are the most highly irradiated gas giant planets, with equilibrium temperatures from 2000 to over 4000 K. Ultra-hot Jupiters are amenable to characterization due to their high temperatures, inflated radii, and short periods, but their atmospheres are atypical for planets in that the photosphere possesses large concentrations of atoms and ions relative to molecules. Here we evaluate how the atmospheres of these planets respond to irradiation by stars of different spectral type. We find that ultra-hot Jupiters exhibit temperature inversions that are sensitive to the spectral type of the host star. The slope and temperature range across the inversion both increase as the host star effective temperature increases due to enhanced absorption at short wavelengths and low pressures. The steep temperature inversions in ultra-hot Jupiters around hot stars result in increased thermal dissociation and ionization compared to similar planets around cooler stars. The resulting increase in H− opacity leads to a transit spectrum that has muted absorption features. The emission spectrum, however, exhibits a large contrast in brightness temperature, a signature that will be detectable with both secondary eclipse observations and high-dispersion spectroscopy. We also find that the departures from local thermodynamic equilibrium in the stellar atmosphere can affect the degree of heating caused by atomic metals in the planet’s upper atmosphere. Additionally, we further quantify the significance of heating by different opacity sources in ultra-hot Jupiter atmospheres.

Abstract
We present a machine-learning (ML) approach for estimating galaxy cluster masses from Chandra mock images. We utilize a Convolutional Neural Network (CNN), a deep ML tool commonly used in image recognition tasks. The CNN is trained and tested on our sample of 7896 Chandra X-ray mock observations, which are based on 329 massive clusters from the

simulation. Our CNN learns from a low resolution spatial distribution of photon counts and does not use spectral information. Despite our simplifying assumption to neglect spectral information, the resulting mass values estimated by the CNN exhibit small bias in comparison to the true masses of the simulated clusters (−0.02 dex) and reproduce the cluster masses with low intrinsic scatter, 8% in our best fold and 12% averaging over all. In contrast, a more standard core-excised luminosity method achieves 15%–18% scatter. We interpret the results with an approach inspired by Google DeepDream and find that the CNN ignores the central regions of clusters, which are known to have high scatter with mass.

Abstract
In this work, we present the analysis of the binary microlensing event OGLE-2018-BLG-0022 that is detected toward the Galactic bulge field. The dense and continuous coverage with the high-quality photometry data from ground-based observations combined with the space-based Spitzer observations of this long timescale event enables us to uniquely determine the masses M
1 = 0.40 ± 0.05 M
⊙ and M
2 = 0.13 ± 0.01 M
⊙ of the individual lens components. Because the lens-source relative parallax and the vector lens-source relative proper motion are unambiguously determined, we can likewise unambiguously predict the astrometric offset between the light centroid of the magnified images (as observed by the Gaia satellite) and the true position of the source. This prediction can be tested when the individual-epoch Gaia astrometric measurements are released.
Characteristics of Long Gamma-Ray Bursts in the Comoving Frame
Authors: Xue Liang , Zhang Fu-Wen , Zhu Si-Yuan 
Published: May 2019

Abstract
We compile a sample of 93 long gamma-ray bursts (GRBs) from the Fermi satellite and 131 from Konus-Wind that have measured redshifts and well-determined spectra, and estimate their pseudo-Lorentz factors (Γ0) using the tight L
iso–E
p–Γ0 correlation. The statistical properties and pair correlations of the temporal and spectral parameters are studied in the observer frame, rest frame, and comoving frame, respectively. We find that the distributions of the duration, peak energy, isotropic energy, and luminosity in the different frames are basically log-normal, and that their distributions in the comoving frame are narrow, clustering around

∼ 4000 s,

∼ 0.7 keV,

∼ 8 × 1049 erg, and

∼ 2.5 × 1046 erg s−1, where the redshift evolution effect has been taken into account. We also find that the values of Γ0 are broadly distributed between a few tens and several hundreds, with median values of ∼270. We further analyze the pair correlations of all the quantities, confirm the E
iso–E
p, L
iso–E
p, L
iso–Γ0, and E
iso–Γ0 relations, and find that the corresponding relations in the comoving frame do still exist, but with large dispersions. This suggests not only that the well-known spectrum–energy relations are intrinsic correlations, but also that the observed correlations are governed by the Doppler effect. In addition, the peak energies of long GRBs are independent of duration both in the rest frame and in the comoving frame, and there is a weak anticorrelation between the peak energy and Lorentz factor.

Abstract
FRB 121102 is the only known repeating fast radio burst source. Here we analyze a wide-frequency-range (1–8 GHz) sample of high signal-to-noise, coherently dedispersed bursts detected using the Arecibo and Green Bank telescopes. These bursts reveal complex time–frequency structures that include subbursts with finite bandwidths. The frequency-dependent burst structure complicates the determination of a dispersion measure (DM); we argue that it is appropriate to use a DM metric that maximizes frequency-averaged pulse structure, as opposed to peak signal-to-noise, and find DM = 560.57 ± 0.07 pc cm−3 at MJD 57,644. After correcting for dispersive delay, we find that the subbursts have characteristic frequencies that typically drift lower at later times in the total burst envelope. In the 1.1–1.7 GHz band, the ∼0.5–1 ms subbursts have typical bandwidths ranging from 100 to 400 MHz, and a characteristic drift rate of ∼200 MHz ms−1 toward lower frequencies. At higher radio frequencies, the subburst bandwidths and drift rate are larger, on average. While these features could be intrinsic to the burst emission mechanism, they could also be imparted by propagation effects in the medium local to the source. Comparison of the burst DMs with previous values in the literature suggests an increase of ΔDM ∼ 1–3 pc cm−3 in 4 yr; though, this could be a stochastic variation as opposed to a secular trend. This implies changes in the local medium or an additional source of frequency-dependent delay. Overall, the results are consistent with previously proposed scenarios in which FRB 121102 is embedded in a dense nebula.
Co-développement et changement
Authors: Duterme Claude 
Published: May 2019

Du point de vue systémique, le changement peut concourir au maintien de l’équilibre d’un ensemble (homéostasie) comme à la modification de certaines des conditions de cet équilibre. Cela cependant ne se fait pas « en soi » ou dans un mode fermé, mais dans un univers du vivant où les ensembles interconnectés s’influencent mutuellement. La co-évolution mène les « systèmes » à s’influencer mutuellement et à s’adapter aux modifications qui s’ensuivent. Dès lors, la qualité perçue d’un changement voulu ou subi dépend essentiellement du contexte dans lequel il est vécu. L’accompagnement systémique et stratégique du changement visera donc d’abord à déterminer le contexte dans lequel il est souhaité, ainsi que les différentes perceptions de ce contexte, et à les reconnaître officiellement. Dans une dynamique participative où l’ensemble des parties concernées sont conviées à s’impliquer pour minimiser les impacts négatifs, l’intervenant devra stratégiquement s’appliquer à contrer les blocages inhérents à la tendance au statu quo interne (« bloquer les blocages »).
Entre éthique, relation et intersubjectivité : pour une nouvelle approche du changement en entreprise
Authors: Cherfi Marc , García-Rivera Teresa , Nicolas Alexis 
Published: May 2019

Dans un contexte de « révolutions » numériques des entreprises, nous assistons comme praticiens du changement, à de nombreuses et fortes ambitions de transformation en profondeur des organisations et de l’action organisée. Cette contribution questionne d’abord le comment du changement. Qu’est-ce qui se joue dans et par ces transformations ? Quelles prémisses président aux stratégies de changement ? Est-ce efficace ? Existe-t-il d’autres voies ? Elle s’inscrit aussi dans un regard critique et réflexif sur notre pratique et une volonté assumée de dé-mécaniser les approches au changement pour ouvrir une troisième voie du changement enfin respectueuse du vivant.
Conduire un diagnostic partagé en contexte inter-organisationnel : enseignements théoriques et pratiques
Authors: Michaux Valéry , Defélix Christian 
Published: May 2019

Les diagnostics partagés entre des organisations situées sur un même territoire visent à décloisonner, créer des synergies et développer des solutions inter-organisationnelles pour des objectifs d’intérêt général. Leur usage est courant dans de nombreux domaines : santé, emploi, formation, reclassement, innovation, gestion territoriale des ressources humaines... Pourtant, la littérature académique est quasi-muette dès lors que l’on cherche à comprendre les facteurs de succès et d’échec de ce type de démarches participatives rendues complexes par le nombre d’organisations différentes concernées. En mobilisant des grilles d’analyse issues du management des organisations, cet article propose un double balisage théorique et empirique qui permet de mieux définir ces démarches, d’en déconstruire les ingrédients et d’en comprendre les déterminants. Il attire l’attention également des praticiens sur quelques points de vigilance.
Le conte-transfert en clinique transculturelle

Published: May 2019

Cet article raconte comment, de la rencontre avec un garçon né en France et d’origine mauritanienne, la clinicienne, face à l’incompréhension et à l’incohérence, a mis en récit les images qui ont émergé dans sa pensée. De ces images, une histoire s’ébauche qui vient révéler les projections, les identifications de la clinicienne au patient, et surtout son contre-transfert culturel. Le conte-transfert en clinique transculturelle invite ici les thérapeutes à écrire ensemble pour, que si « se chevauche l’aire du patient et celle du thérapeute » l’écriture puisse rendre à chacun sa part d’indicible.
Analyse des facteurs influençant l’émergence des pratiques de télémédecine : le cas des Maisons de Santé en France
Authors: Habib Johanna , Yatim Fatima , Sebai Jihane 
Published: May 2019

En réponse à un contexte à la fois complexe et fragile marqué par une volonté d’amélioration de la qualité des soins et de maîtrise des dépenses de santé, les SI sont appréhendés comme l’un des socles essentiels de la refonte organisationnelle actuelle du système de santé. Plus particulièrement, la télémédecine apparaît comme une innovation organisationnelle indispensable pour pallier les faiblesses du système et assurer l’accessibilité à tous à des soins de qualité. Considéré comme un maillon du processus de soin, le développement de la télémédecine semble exiger un changement organisationnel et culturel important pour les structures de soins et leurs patients. Partant de ce contexte, notre recherche propose d’étudier les facteurs de nature technologique, organisationnelle et externe susceptibles de favoriser l’émergence des pratiques de télémédecine dans les maisons de santé en France. Pour cela, nous combinons dans une approche exploratoire deux sources de données. La première source de données, de nature secondaire et déclarative, mobilise le bilan établi à la fin de l’année 2014 par l’Observatoire des recompositions de l’offre de soins de la Direction Générale de l’Offre de Soins (DGOS) concernant les maisons de santé recensées depuis 2008 sur le territoire français. Pour approfondir cette première analyse, une seconde source de données de nature qualitative a été mobilisée. Celle-ci repose sur vingt-deux entretiens auprès d’acteurs impliqués dans la mise en place de dispositifs de télémédecine au sein de ces maisons de santé. Les résultats de cette recherche révèlent que l’émergence des pratiques de la télémédecine semble influencée par une logique de besoins de coordination externe sur le territoire de soins davantage que par une logique de croissance interne ou de maturité structurelle ou technologique. Sur ce dernier point, celui de la maturité technologique, nous observons au contraire un développement concomitant des projets de SI intégré et de télémédecine. Fort de ce résultat, la principale contribution théorique de cette recherche est de discuter le lien entre intégration interne et externe au sein des trajectoires d’informatisation.
