SCATTERING MATRIX FOR THE INTERACTION BETWEEN SOLAR ACOUSTIC WAVES AND SUNSPOTS. I. MEASUREMENTS
Authors: Yang Ming-Hsu , Chou Dean-Yi , Zhao Hui
Published: January 2017

Assessing the interaction between solar acoustic waves and sunspots is a scattering problem. The scattering matrix elements are the most commonly used measured quantities to describe scattering problems. We use the wavefunctions of scattered waves of NOAAs 11084 and 11092 measured in the previous study to compute the scattering matrix elements, with plane waves as the basis. The measured scattered wavefunction is from the incident wave of radial order n to the wave of another radial order n′, for

. For a time-independent sunspot, there is no mode mixing between different frequencies. An incident mode is scattered into various modes with different wavenumbers but the same frequency. Working in the frequency domain, we have the individual incident plane-wave mode, which is scattered into various plane-wave modes with the same frequency. This allows us to compute the scattering matrix element between two plane-wave modes for each frequency. Each scattering matrix element is a complex number, representing the transition from the incident mode to another mode. The amplitudes of diagonal elements are larger than those of the off-diagonal elements. The amplitude and phase of the off-diagonal elements are detectable only for

Hot dust-obscured galaxies (hot DOGs), selected from Wide-Field Infrared Survey Explorer’s all-sky infrared survey, host some of the most powerful active galactic nuclei known and may represent an important stage in the evolution of galaxies. Most known hot DOGs are located at

, due in part to a strong bias against identifying them at lower redshift related to the selection criteria. We present a new selection method that identifies 153 hot DOG candidates at

, where they are significantly brighter and easier to study. We validate this approach by measuring a redshift z = 1.009 and finding a spectral energy distribution similar to that of higher-redshift hot DOGs for one of these objects, WISE J1036+0449 (

, a value significantly lower than that expected from the mid-infrared/X-ray correlation. We also find that other hot DOGs observed by X-ray facilities show a similar deficiency of X-ray flux. We discuss the origin of the X-ray weakness and the absorption properties of hot DOGs. Hot DOGs at

could be excellent laboratories to probe the characteristics of the accretion flow and of the X-ray emitting plasma at extreme values of the Eddington ratio.

We observed the [C ii] line in 15 lensed galaxies at redshifts 1 < z < 3 using HIFI on the Herschel Space Observatory and detected 14/15 galaxies at 3σ or better. High magnifications enable even modestly luminous galaxies to be detected in [C ii] with Herschel. The [C ii] luminosity in this sample ranges from 8 × 107
L
⊙ to 3.7 × 109
L
⊙ (after correcting for magnification), confirming that [C ii] is a strong tracer of the ISM at high redshifts. The ratio of the [C ii] line to the total far-infrared (FIR) luminosity serves as a measure of the ratio of gas to dust cooling and thus the efficiency of the grain photoelectric heating process. It varies between 3.3% and 0.09%. We compare the [C ii]/FIR ratio to that of galaxies at z = 0 and at high redshifts and find that they follow similar trends. The [C ii]/FIR ratio is lower for galaxies with higher dust temperatures. This is best explained if increased UV intensity leads to higher FIR luminosity and dust temperatures, but gas heating does not rise due to lower photoelectric heating efficiency. The [C ii]/FIR ratio shows weaker correlation with FIR luminosity. At low redshifts highly luminous galaxies tend to have warm dust, so the effects of dust temperature and luminosity are degenerate. Luminous galaxies at high redshifts show a range of dust temperatures, showing that [C ii]/FIR correlates most strongly with dust temperature. The [C ii] to mid-IR ratio for the HELLO sample is similar to the values seen for low-redshift galaxies, indicating that small grains and PAHs dominate the heating in the neutral ISM, although some of the high [CII]/FIR ratios may be due to turbulent heating.
DYNAMIC DEUTERIUM ENRICHMENT IN COMETARY WATER VIA ELEY–RIDEAL REACTIONS
Authors: Yao Yunxi , Giapis Konstantinos P.
Published: January 2017

The deuterium-to-hydrogen ratio (D/H) in water found in the coma of Jupiter family comet (JFC) 67P/Churyumov–Gerasimenko was reported to be (5.3 ± 0.7) × 10−4, the highest among comets and three times the value for other JFCs with an ocean-like ratio. This discrepancy suggests the diverse origins of JFCs and clouds the issue of the origin of Earth’s oceanic water. Here we demonstrate that Eley–Rideal reactions between accelerated water ions and deuterated cometary surface analogs can lead to instantaneous deuterium enrichment in water scattered from the surface. The reaction proceeds with H2O+ abstracting adsorbed D atoms, forming an excited H2DO* state, which dissociates subsequently to produce energetic HDO. Hydronium ions are also produced readily by the abstraction of H atoms, consistent with H3O+ detection and abundance in various comets. Experiments with water isotopologs and kinematic analysis on deuterated platinum surfaces confirmed the dynamic abstraction mechanism. The instantaneous fractionation process is independent of the surface temperature and may operate on the surface of cometary nuclei or dust grains, composed of deuterium-rich silicates and carbonaceous chondrites. The requisite energetic water ions have been detected in the coma of 67P in two populations. This dynamic fractionation process may temporarily increase the water D/H ratio, especially as the comet gets closer to the Sun. The magnitude of the effect depends on the water ion energy-flux and the deuterium content of the exposed cometary surfaces.

) HI bearing dwarf galaxies ALFAZOAJ1952+1428 and KK246 have been imaged with Hubble Space Telescope in order to study the stellar populations and determine distances from the luminosities of stars at the tip of the red giant branch. The mixed age systems have respective distances of 8.39 Mpc and 6.95 Mpc and inferred line-of-sight peculiar velocities of −114 km s−1 and −66 km s−1 toward us and away from the void center. These motions compound on the Milky Way motion of ∼230 km s−1 away from the void. The orbits of the two galaxies are reasonably constrained by a numerical action model encompassing an extensive region that embraces the Local Void. It is unambiguously confirmed that these two void galaxies are moving away from the void center at several hundred km s−1.
NEW DETECTIONS OF HNC IN PLANETARY NEBULAE: EVOLUTION OF THE [HCN]/[HNC] RATIO

These values are greatly reduced from what has been found in asymptotic giant branch stars, where the ratio is typically >100. Both the abundance of HNC and the [HCN]/[HNC] ratio do not appear to vary significantly with nebular age across a time span of ∼10,000 years, in contrast to predictions of chemical models. The increase in HNC appears to arise in the proto-planetary stage, but becomes “frozen” once the PN phase is reached.

We consider the chemodynamical properties of these stars in concert with a similarly local sample of stars from a recent analysis of the Bidelman and MacConnell “weak metal” candidates by Beers et al. We use this combined sample to identify possible members of the halo stream of stars suggested by Helmi et al. and Chiba & Beers, as well as stars that may be associated with stripped debris from the putative parent dwarf of the globular cluster Omega Centauri, suggested to exist by previous authors. We identify a clear increase in the cumulative frequency of carbon-enhanced metal-poor (CEMP) stars with declining metallicity, as well as an increase in the fraction of CEMP stars with distance from the Galactic plane, consistent with previous results. We also identify a relatively large number of CEMP stars with kinematics consistent with the metal-weak thick-disk population, with possible implications for its origin.
SIMULATION STUDY OF HEMISPHERIC PHASE-ASYMMETRY IN THE SOLAR CYCLE
Authors: Shukuya D. , Kusano K.
Published: January 2017

Observations of the Sun suggest that solar activities systematically create north–south hemispheric asymmetries. For instance, the hemisphere in which sunspot activity is more active tends to switch after the early half of each solar cycle. Svalgaard & Kamide recently pointed out that the time gaps of polar field reversal between the northern and southern hemispheres are simply consequences of the asymmetry of sunspot activity. However, the mechanism underlying the asymmetric feature in solar cycle activity is not yet well understood. In this paper, in order to explain the cause of the asymmetry from the theoretical point of view, we investigate the relationship between the dipole- and quadrupole-type components of the magnetic field in the solar cycle using the mean-field theory based on the flux transport dynamo model. As a result, we found that there are two different attractors of the solar cycle, in which either the north or the south polar field is first reversed, and that the flux transport dynamo model explains well the phase-asymmetry of sunspot activity and the polar field reversal without any ad hoc source of asymmetry.
THE ROLE OF MAGNETIC HELICITY IN STRUCTURING THE SOLAR CORONA
Authors: Knizhnik K. J. , Antiochos S. K. , DeVore C. R.
Published: January 2017

Two of the most widely observed and striking features of the Sun's magnetic field are coronal loops, which are smooth and laminar, and prominences or filaments, which are strongly sheared. Loops are puzzling because they show little evidence of tangling or braiding, at least on the quiet Sun, despite the chaotic nature of the solar surface convection. Prominences are mysterious because the origin of their underlying magnetic structure—filament channels—is poorly understood at best. These two types of features would seem to be quite unrelated and wholly distinct. We argue that, on the contrary, they are inextricably linked and result from a single process: the injection of magnetic helicity into the corona by photospheric motions and the subsequent evolution of this helicity by coronal reconnection. In this paper, we present numerical simulations of the response of a Parker (1972) corona to photospheric driving motions that have varying degrees of helicity preference. We obtain four main conclusions: (1) in agreement with the helicity condensation model of Antiochos (2013), the inverse cascade of helicity by magnetic reconnection in the corona results in the formation of filament channels localized about polarity inversion lines; (2) this same process removes most complex fine structure from the rest of the corona, resulting in smooth and laminar coronal loops; (3) the amount of remnant tangling in coronal loops is inversely dependent on the net helicity injected by the driving motions; and (4) the structure of the solar corona depends only on the helicity preference of the driving motions and not on their detailed time dependence. We discuss the implications of our results for high-resolution observations of the corona.

TEST OF PARAMETRIZED POST-NEWTONIAN GRAVITY WITH GALAXY-SCALE STRONG LENSING SYSTEMS

Published: January 2017

Based on a mass-selected sample of galaxy-scale strong gravitational lenses from the SLACS, BELLS, LSD, and SL2S surveys and using a well-motivated fiducial set of lens-galaxy parameters, we tested the weak-field metric on kiloparsec scales and found a constraint on the post-Newtonian parameter

under the assumption of a flat ΛCDM universe with parameters taken from Planck observations. General relativity (GR) predicts exactly γ = 1. Uncertainties concerning the total mass density profile, anisotropy of the velocity dispersion, and the shape of the light profile combine to systematic uncertainties of ∼25%. By applying a cosmological model-independent method to the simulated future LSST data, we found a significant degeneracy between the PPN γ parameter and the spatial curvature of the universe. Setting a prior on the cosmic curvature parameter −0.007 < Ω

Published: January 2017

It has been revealed that the magnetic topology in the solar atmosphere displays hemispheric preference, i.e., helicity is mainly negative/positive in the northern/southern hemispheres, respectively. However, the strength of the hemispheric rule and its cyclic variation are controversial. In this paper, we apply a new method based on the filament drainage to 571 erupting filaments from 2010 May to 2015 December in order to determine the filament chirality and its hemispheric preference. It is found that 91.6% of our sample of erupting filaments follows the hemispheric rule of helicity sign. It is also found that the strength of the hemispheric preference of the quiescent filaments decreases slightly from ∼97% in the rising phase to ∼85% in the declining phase of solar cycle 24, whereas the strength of the intermediate filaments keeps a high value around 96 ± 4% at all times. Only the active-region filaments show significant variations. Their strength of the hemispheric rule rises from ∼63% to ∼95% in the rising phase, and keeps a high value of 82% ± 5% during the declining phase. Furthermore, during a half-year period around the solar maximum, their hemispheric preference totally vanishes. Additionally, we also diagnose the magnetic configurations of the filaments based on our indirect method and find that in our sample of erupting events, 89% are inverse-polarity filaments with a flux rope magnetic configuration, whereas 11% are normal-polarity filaments with a sheared arcade configuration.

GJ 1214b is the most studied sub-Neptune exoplanet to date. Recent measurements have shown its near-infrared transmission spectrum to be flat, pointing to a high-altitude opacity source in the exoplanet's atmosphere, either equilibrium condensate clouds or photochemical hazes. Many photometric observations have been reported in the optical by different groups, though simultaneous measurements spanning the entire optical regime are lacking. We present an optical transmission spectrum (4500–9260 Å) of GJ 1214b in 14 bins, measured with Magellan/IMACS repeatedly over three transits. We measure a mean planet-to-star radius ratio of

We present a model for jointly incorporating the effects of a composite photosphere and atmospheric transmission through the exoplanet's limb (the CPAT model), and use it to examine the cases of absorber and temperature heterogeneities in the stellar photosphere. We find the optical and near-infrared measurements are best explained by the combination of (1) photochemical haze in the exoplanetary atmosphere with a mode particle size r = 0.1 μm and haze-forming efficiency

SYSTEMATIC VARIATIONS OF MACROSPICULE PROPERTIES OBSERVED BY SDO/AIA OVER HALF A DECADE
Authors: Kiss T. S. , Gyenge N. , Erdélyi R.
Published: January 2017

Macrospicules (MSs) are localized small-scale jet-like phenomena in the solar atmosphere, which have the potential to transport a considerable amount of momentum and energy from the lower solar atmospheric regions to the transition region and the low corona. A detailed statistical analysis of their temporal behavior and spatial properties is carried out in this work. Using state-of-the-art spatial and temporal resolution observations, yielded by the Atmospheric Imaging Assembly of Solar Dynamics Observatory, we constructed a database covering a 5.5 year long period, containing 301 macrospicules that occurred between 2010 June and 2015 December, detected at 30.4 nm wavelength. Here, we report the long-term variation of the height, length, average speed, and width of MS in coronal holes and Quiet Sun areas both in the northern and southern hemisphere of the Sun. This new database helps to refine our knowledge about the physical properties of MSs. Cross-correlation of these properties shows a relatively strong correlation, but not always a dominant one. However, a more detailed analysis indicates a wave-like signature in the behavior of MS properties in time. The periods of these long-term oscillatory behaviors are just under two years. Also, in terms of solar north/south hemispheres, a strong asymmetry was found in the spatial distribution of MS properties, which may be accounted for by the solar dynamo. This latter feature may then indicate a strong and rather intrinsic link between global internal and local atmospheric phenomena in the Sun.

We present results from the first observations of the Hubble Space Telescope (HST) Panchromatic Comparative Exoplanet Treasury program for WASP-101b, a highly inflated hot Jupiter and one of the community targets proposed for the James Webb Space Telescope (JWST) Early Release Science (ERS) program. From a single HST Wide Field Camera 3 observation, we find that the near-infrared transmission spectrum of WASP-101b contains no significant H2O absorption features and we rule out a clear atmosphere at 13σ. Therefore, WASP-101b is not an optimum target for a JWST ERS program aimed at observing strong molecular transmission features. We compare WASP-101b to the well-studied and nearly identical hot Jupiter WASP-31b. These twin planets show similar temperature–pressure profiles and atmospheric features in the near-infrared. We suggest exoplanets in the same parameter space as WASP-101b and WASP-31b will also exhibit cloudy transmission spectral features. For future HST exoplanet studies, our analysis also suggests that a lower count limit needs to be exceeded per pixel on the detector in order to avoid unwanted instrumental systematics.
ALMA Observations of the Water Fountain Pre-planetary Nebula IRAS 16342-3814: High-velocity Bipolar Jets and an Expanding Torus

Published: January 2017

We have mapped 12CO J = 3–2 and other molecular lines from the “water fountain” bipolar pre-planetary nebula (PPN) IRAS 16342-3814 with ∼0.″35 resolution using Atacama Large Millimeter/submillimeter Array. We find (i) two very high-speed knotty, jet-like molecular outflows; (ii) a central high-density (

cm−3), expanding torus of diameter 1300 au; and (iii) the circumstellar envelope of the progenitor AGB, generated by a sudden, very large increase in the mass-loss rate to

M
⊙ yr−1 in the past ∼455 years. Strong continuum emission at 0.89 mm from a central source (690 mJy), if due to thermally emitting dust, implies a substantial mass (0.017 M
⊙) of very large (∼millimeter-sized) grains. The measured expansion ages of the above structural components imply that the torus (age ∼160 years) and the younger high-velocity outflow (age ∼110 years) were formed soon after the sharp increase in the AGB mass-loss rate. Assuming a binary model for the jets in IRAS 16342, the high momentum rate for the dominant jet-outflow in IRAS 16342 implies a high minimum accretion rate, ruling out standard Bondi–Hoyle–Lyttleton wind accretion and wind Roche-lobe overflow (RLOF) models with white-dwarf or main-sequence companions. Most likely, enhanced RLOF from the primary or accretion modes operating within common-envelope evolution are needed.
Histoire, développements et formes de la psychanalyse en Italie
Authors: Ferruta Anna , Galazzi Mariella
Published: January 2017

Cet article invite à un voyage conceptuel tout au long du développement de la psychanalyse en Italie, de la fondation de la Società Psicoanalitica par l’élève de Freud, Edoardo Weiss, en 1925 jusqu’à son expansion actuelle, qui voit Stefano Bolognini, président de l’ipa depuis 2013, et Antonino Ferro comme l’un des psychanalystes les plus renommés et appréciés au niveau international. La psychanalyse italienne conserve des traces importantes de ses débuts : le lien avec le texte freudien et avec la Société psychanalytique internationale, le rapport étroit avec la clinique et l’intérêt pour l’articulation avec la culture et la société. Les principaux thèmes conceptuels développés sont ici exposés : la relation analytique, un véritable modèle du travail analytique au centre duquel s’articule le dialogue en spirale du couple analytique formé par un patient – le meilleur collègue – et par un analyste doué de rêverie et d’une écoute respectueuse ; le fonctionnement psychique de l’analyste, comme contenant transformatif des contenus portés par l’analysant, mais aussi comme personne qui entre dans la formation des constructions en analyse avec les caractéristiques de sa culture et de son histoire individuelle ; l’approfondissement des premières phases du développement psychique, qui constitue un facteur multipliant l’intérêt et la communication parmi les analystes d’origine et de provenance différentes, la recherche d’une nouvelle configuration symbolique durant l’adolescence et l’écoute des communications non verbales. Le but de la psychanalyse clinique n’est plus un dévoilement mais une récupération et une construction de ce qui n’a pu se développer au cours des relations précédentes.
Aux confins du pensable
Authors: Boccara Paolo , Caprarelli Anna
Published: January 2017

L’auteur retrace ici les étapes qui ont marqué l’abolition de l’internement forcé en Italie. Une révolution, initiée par Franco Basaglia, qui se poursuit encore aujourd’hui. Son action aboutira après la loi Basaglia, promulguée en 1978, à la fermeture de la grande majorité des hôpitaux psychiatriques italiens. L’idée de base est de traiter les patients comme des personnes et de pratiquer « la meilleure des psychiatries possibles », restaurer le droit des individus et leur dignité, cesser de considérer les malades comme des objets et impliquer chaque intervenant et chaque secteur du champ institutionnel. La subjectivité de chaque malade mérite d’être prise en compte. Depuis les années 1970 jusqu’à aujourd’hui, trois générations de psychanalystes se sont succédé, se confrontant à des intervenants de professions et de formations diverses. La fermeture des hôpitaux psychiatriques en a été la condition fondamentale en redéfinissant la manière de prendre réellement en charge les personnes en souffrance soit en recherchant les soins les mieux adaptés pour atténuer leur douleur et améliorer leur environnement.
Avant la douleur

Published: January 2017

L’auteur décrit la souffrance d’un homme lors de sa troisième expérience analytique. Frêle à la manière d’un adolescent, il avait dissimulé sa fragilité, lors de sa première rencontre avec l’analyste, sous un long manteau qui lui arrivait presque aux pieds. Il buvait beaucoup et jouait au poker. Ses pertes, importantes, il les vivait comme protection et sauvegarde face aux autres menaces existentielles appréhendées. « Si je ne perdais pas au poker, disait-il, je n’aurais même pas le courage de sortir de chez moi. » Il fut difficile de comprendre pour quelles fautes – ou quelles fortunes – il se sentait ainsi menacé. On pressentait quelque chose du côté de la sexualité, du désir incestueux inspiré par ses sœurs, mais aussi dans le conflit muet et féroce avec son père, dont il ne s’était jamais senti apprécié, plutôt ouvertement dévalorisé, en dépit de ses bonnes performances scolaires. Sa mère ? Il n’en a quasiment jamais parlé. Ni en bien ni en mal, il ne semblait pas pouvoir la faire affleurer. Ces relations se sont déclinées à travers le transfert dans des dynamiques d’une bouleversante intensité dans la souffrance. Des années après la fin de son analyse, l’auteur reçut l’annonce de sa mort : un suicide selon certains, un accident selon sa femme. Ce texte rapporte des séquences où l’absence de la capacité de se contenir se manifeste à travers des actings (passages à l’acte) racontés ou directement agis en séance.

Dans cet article, l’auteur présente son modèle post-bionien, avec pour objectif le développement d’outils à penser aptes à ressentir plutôt que de traquer les contenus clivés ou refoulés. Sont mis en évidence les facteurs thérapeutiques qui autorisent le renforcement progressif de la fonction de contenant et de ce qui relève de l’onirique. Un processus rendu possible par le travail du champ, où pullulent les éléments inconscients ou non mentalisés, transformés de manière continue en pensable, grâce au phénomène de casting et de la transformation en rêve. L’analyste présente live ses « échanges » avec quelques patients, au cours de séances où rêveries-flashes/courts-métrages ou encore des rêveries-constructions/longs-métrages se déploient sans entraves. Sont ici présentés : Liliana, aux prises avec ses engorgements ; Francesco/Francesca à la découverte de quelques « recoins » jusque-là inaccessibles ; Amanda ou mademoiselle demi-portion, dont l’inertie réside dans une moitié perdue, et quelques autres personnages du champ analytique, pour transmettre l’idée que si l’espace « transformationnel » passe par un style conversationnel , il est l’un des moteurs de l’analyse comme l’interprétation est, parfois, ce qui ouvre à des horizons nouveaux.
La mémoire et la réparation, la psychanalyse et la question de la mort
Authors: de Masi Franco
Published: January 2017

Questionner sa propre mort est se confronter aux limites de la pensée. Or, si la mort n’est pas pensable, qu’entendons-nous par « peur de la mort » ? L’hypothèse de ce travail est que la mort s’inscrit dans le monde interne de chacun sous la forme d’un désastre – d’un état de désintégration de l’identité personnelle – difficilement concevable ou tolérable. À mesure que nous avançons en âge, l’intégration continue du passé, qui prend sens dès lors que l’on accepte la nature éphémère du Soi individuel, permet de le projeter dans l’avenir des autres, en nous évitant ainsi le sentiment catastrophique qu’implique une dissolution dans le néant de la non-existence.
Le paternel comme dimension régulatrice évolutive du masculin
Authors: Vigna-Taglianti Massimo , Angelini-Rota Antonella
Published: January 2017

Je voudrais proposer l’hypothèse selon laquelle, dans des situations caractérisées par l’absence du père et/ou par l’absence d’un objet paternel « actif » dans la psyché de la mère, un dérèglement marqué du développement de la dimension masculine peut apparaître. Le but de ce travail est donc d’explorer la manière dont une défaillance de la fonction paternelle peut, en dernière analyse, contribuer à structurer un contenant psychique déficient sur le plan de la représentation du masculin ou déficitaire dans la gestion et dans la transformation des contenus masculins de la psyché, liés de manière plus générale à la violence des émotions générées par les sollicitations provenant de la réalité aussi bien intérieure qu’extérieure.
Apophatic Austen: Speaking about Silence in Austen’s Fiction
Authors: Toner Anne
Published: January 2017

Cet article examine l’intérêt d’Austen pour la figure rhétorique de la prétérition, qui se produit lorsqu’un locuteur annonce qu’il ne dit pas quelque chose tout en le disant. Adolescente, Austen s’était moquée de l’utilisation de ce procédé, notamment dans « Jack and Alice », court texte de fiction inclus dans la collection du premier tome de ses manuscrits. À ce stade très précoce de sa carrière d’écrivaine, Austen explore les manières conventionnelles de rester faussement silencieux. Si le contexte dans lequel furent écrits ses textes de jeunesse est explicité ici, il est aussi montré que cette figure joue un rôle dans l’innovation technique la plus célèbre des textes de sa maturité, le développement du discours indirect libre, qui se structure pareillement autour des paradoxes de dire et ne pas dire.
From Silence to “Civil Converse”: Of the Attempts to Control Seventeenth-Century Women’s “Ripe Wit and Ready Tongues”
Authors: Lardy Michèle
Published: January 2017

Tout au long du xviie siècle, « Discrétion, Silence et Décence » demeurent trois qualités exigées des femmes. Au début du siècle, des pamphlets misogynes attaquent les femmes qui, avec leur « langue bien pendue », séduisent puis dominent les hommes. Les auteurs de traités, pour leur part, répètent qu’on « devrait voir, et non entendre » les femmes, invitées à contrôler cet organe sous peine d’être soupçonnées d’indécence. Dans la seconde moitié du siècle, les manuels de conduite insistent davantage sur un ensemble de règles permettant d’accorder un « discours courtois », « raisonnable et opportun » à une conduite irréprochable, garant d’une réputation sans tache.
Margaret Cavendish’s Femmes Fortes: The Paradoxes of Female Heroism in Bell in Campo (1662)
Authors: Gheeraert-Graffeuille Claire
Published: January 2017

Cet article se propose de lire la pièce Bell in Campo (1662) de Margaret Cavendish à la lumière du traité de Pierre Le Moyne, La Gallerie des femmes fortes (1647). Il montre de quelle manière ce traité à la gloire des femmes éclaire la mise en scène ambiguë de l’héroïsme féminin dans Bell in Campo. Comme le jésuite français, Cavendish utilise les exploits de femmes à la fois pour mettre en évidence les enjeux de l’émancipation féminine et pour donner forme à ses propres réflexions politiques et anthropologiques. Afin d’analyser ce double regard porté sur le genre et la politique, l’article étudie successivement la crise de l’éthos héroïque, la construction du personnage de la guerrière, et les différentes interprétations possibles du triomphe de Lady Victoria. Il montre enfin que dans le contexte incertain de la Guerre Civile, il est possible de comprendre l’héroïsme féminin de Lady Victoria comme une défense des valeurs royalistes et aristocratiques.
Efeitos do uso de fortificante do leite humano em recém-nascidos pré-termo de muito baixo peso/ The effects of using the human breast milk fortifier in pre-term of very low weight newly born

O leite materno é o alimento ideal para qualquer recém-nascido devido à sua composição nutricional balanceada e à sua capacidade de gerar imunidade. Seu uso tem sido muito incentivado nas Unidades de Terapia Intensiva (UTI) e Unidades Intermediárias (UI), sendo ofertados tanto o leite materno extraído diretamente do seio materno, quanto o proveniente de bancos de leite humano. Dessa forma, este estudo teve como propósito acompanhar e comparar recém-nascidos com e sem o uso de aditivo fortificante do leite materno, em UTI neonatal. O estudo foi observacional do tipo coorte, com grupo controle, realizado em uma maternidade pública, nas unidades de terapia intensiva e terapia intermediária neonatais. Foram acompanhados 26 recém-nascidos pré-termo, divididos em dois grupos, um deles constituído por 13 recém-nascidos em aleitamento materno exclusivo (grupo controle) e outro composto por 13 recém-nascidos em uso de leite materno, com aditivo fortificante. Para a análise de dados, foi utilizada estatística descritiva simples, calculando-se distribuições de frequências, cálculo das médias, desvio-padrão e realizações dos testes estatísticos. O ganho de peso médio no período do estudo foi significativamente maior no grupo que recebeu leite materno com aditivo. Em relação ao comprimento e ao perímetro cefálico não foram observadas diferenças estatísticas significativas entre os grupos. Constata-se que o uso de aditivo no leite materno humano cru ou processado proporciona melhor ganho de peso, favorecendo a recuperação do estado nutricional.

Neste estudo objetivou-se analisar o acolhimento à mulher na Estratégia Saúde da Família em situações de violência. De caráter qualitativo, do tipo descritivo, este estudo foi realizado com 53 profissionais de sete equipes da Estratégia Saúde da Família de um município da região noroeste do estado do Rio Grande do Sul. Os dados foram produzidos pela técnica de observação não participante, registrados em diário de campo e analisados pela modalidade temática de Bardin. Os resultados mostram que os espaços físicos não propiciam condições de privacidade e acesso às mulheres em situação de violência. Parte dos profissionais preocupa-se em investigar situações de vida, mas a violência não. Uma das unidades tem identificado, no mapa inteligente, as mulheres em situação de violência e um fluxograma para atender a violência sexual. Conclui-se que é preciso repensar o acolhimento à mulher em situação de violência, propor a inclusão do problema na agenda e organizar os serviços com base na política.

Published: January 2017

The density functional theory within generalized gradient approximation (GGA) has been used to calculate lattice parameter, total energy, phase transition pressure and electronic properties of neptunium sulphide (NpS). From our calculations we observe that NpS is stable in NaCl – type structure under ambient pressure. For this compound, the phase transition pressure was found to be 29.5 GPa. The nature of metallic behaviour is remarked from energy band diagram in NpS. All properties obtained for this compound are in good agreement with available results.
Maternal health service disparities across incomes and implications on prevention of mother-to-child transmission service coverage: current context in Sub-Saharan Africa
Authors: Workneh Nibretie Gobezie , Kevany Sebastian
Published: January 2017

About 69% of people living with HIV globally and over 90% of the children who acquired HIV infection are in Sub-Saharan Africa. Despite this, promising results have been observed, especially over the last decade – for example, a 25% decline in new HIV infections as compared to 2001 and a 38% decline in the number of children newly infected by HIV in 2012 as compared to 2009. However, the Global Plan and the Global Fast-Track Commitments of eliminating new HIV infections among children require addressing impediments to service expansion. In this regard, this paper attempts to draw attention to the extent to which disparities across income in using antenatal care (ANC) services may constrain the prevention of mother-to-child transmission (PMTCT) service expansion in Sub-Saharan Africa. The analysis is based on ANC service coverage data from Demographic and Health Surveys conducted between 2008 and 2015 in 31 Sub-Saharan African countries; and PMTCT coverage data from UNAIDS datasets released in 2016. Our analysis found that women in the highest wealth quintile are about three times more likely to frequently use ANC services (at least four visits) as compared to those in the lowest wealth quintile (95%CI: 1.7-5.7, P<0.0001). A regression analysis shows that one-quarter of the PMTCT service coverage can be explained by the disparity in ANC use associated with income; and the higher the disparity in ANC use, the lower the PMTCT service (P<0.05). The findings suggest that achieving the ambitious plan of zero new HIV infections among children while keeping their mothers alive will require on-going PMTCT/ANC service integration and ensuring that programs reach women who are most in need; specifically those in the poorest income categories.
Low coverage of hepatitis B vaccine and determinants among health professionals working in Amhara regional state hospitals, Ethiopia
Authors: Feleke Berhanu Elfu
Published: January 2017

More than two billion people have been infected with hepatitis B virus (HBV), 360 million have chronic infection and 600,000 die each year from HBV-related liver disease or hepatocellular carcinoma. Each year more than 66,000 health professionals are infected by hepatitis b virus and vaccination against hepatitis B saves the life’s of these health professionals. The aim of this study was to determine the prevalence and associated factors of hepatitis B vaccine coverage in a resource limited settings. A cross sectional study design was conducted. The study was conducted on 1184 health professionals at Amhara national regional state, Ethiopia. Simple random sampling technique was used. Structured questionnaire was used to collect the data. Descriptive statistics were used to identify the prevalence while Binary logistic regression was used to assess the determinants of hepatitis B vaccine coverage. The coverage of hepatitis B vaccine was 4%. Vaccination were affected by work load (AOR=0.19, 95%CI= 0.08-0.46; P<0.01), negligence (AOR=0.04, 95%CI=0.01- 0.11: P<0.01), universal precaution training (AOR=14.75, 95%CI=5.66-38.44: P<0.01), perception that they are not at risk of infection (AOR=0.34, 95%CI=0.15-0.79: P=0.01), unaffordable cost (AOR=0.12, 95%CI=0.05-0.28: P<0.01), awareness about the vaccine (AOR=4.55, 95%CI=1.53-13.49: P<0.01), peer pressure (AOR=3.8, 95%CI=1.34-10.74: P=0.01), knowledge about where to get the vaccine (AOR=5.13, 95%CI=1.87-14.11: P=0.02), unavailability of the vaccine (AOR=0.25, 95%CI=0.1-0.63: P=0.03), year of experience (AOR=7.27, 95%CI=2.23-23.72: P<0.01). Low hepatitis B vaccine coverage was observed. The ministry of health should avail the vaccine to all those health professionals, develop awareness on HBV and improve the affordability of the vaccine.
A study on strategic planning and procurement of medicals in Uganda’s regional referral hospitals
Authors: Masembe Ishak Kamaradi
Published: January 2017

This study was an analysis of the effect of strategic planning on procurement of medicals in Uganda’s regional referral hospitals (RRH’s). Medicals were defined as essential medicines, medical devices and medical equipment. The Ministry of Health (MOH) has been carrying out strategic planning for the last 15 years via the Health Sector Strategic Plans. Their assumption was that strategic planning would translate to strategic procurement and consequently, availability of medicals in the RRH’s. However, despite the existence of these plans, there have been many complaints about expired drugs and shortages in RRH’s. For this purpose, a third variable was important because it served the role of mediation. A questionnaire was used to obtain information on perceptions of 206 respondents who were selected using simple random sampling. 8 key informant interviews were held, 2 in each RRH. 4 Focus Group Discussions were held, 1 for each RRH, and between 5 and 8 staff took part as discussants for approximately three hours. The findings suggested that strategic planning was affected by funding to approximately 34% while the relationship between funding and procurement was 35%. The direct relationship between strategic planning and procurement was 18%. However when the total causal effect was computed it turned out that strategic planning and the related variable of funding contributed 77% to procurement of medicals under the current hierarchical model where MOH is charged with development of strategic plans for the entire health sector. Since even with this contribution there were complaints, the study proposed a new model called CALF which according to a simulation, if adopted by MOH, strategic planning would contribute 87% to effectiveness in procurement of medicals.
