THE SPATIALLY RESOLVED NUV–r COLOR OF LOCAL STAR-FORMING GALAXIES AND CLUES FOR QUENCHING
Authors: Pan Zhizheng , Zheng Xianzhong , Lin Weipeng , Li Jinrong , Wang Jing , Fan Lulu , Kong Xu 
Published: March 2016

ABSTRACT
Using a sample of ∼6000 local face-on star-forming galaxies (SFGs) we examine the correlations between the NUV–r colors both inside and outside the half-light radius, stellar mass M
*, and Sérsic index n to understand how the quenching of star formation is linked to galaxy structure. For these less dust-attenuated galaxies, NUV–r is found to be linearly correlated with

, supporting NUV–r as a good photometric indicator of stellar age (or specific star formation rate). First, we find that at

the central NUV–r is on average only ∼0.25 mag redder than the outer NUV–r; the intrinsic value would be even smaller after accounting for dust correction. However, the central NUV–r becomes systematically much redder than the outer NUV–r for more massive galaxies at

. Second, the central NUV–r shows no dependence on Sérsic index n at

, while above this mass galaxies with a higher n tend to be redder in the central NUV–r color. These results suggest that galaxies with

exhibit similar star formation activity from the inner

region to the

region. In contrast, a considerable fraction of the

galaxies, especially those with a high n, have harbored a relatively inactive bulge component.
BAR INSTABILITY IN DISK–HALO SYSTEMS
Authors: Sellwood J. A. 
Published: March 2016

ABSTRACT
We show that the exponential growth rate of a bar in a stellar disk is substantially greater when the disk is embedded in a live halo than in a rigid one having the same mass distribution. We also find that the vigor of the instability in disk–halo systems varies with the shape of the halo velocity ellipsoid. Disks in rigid halos that are massive enough to be stable by the usual criteria, quickly form bars in isotropic halos and much greater halo mass is needed to avoid a strong bar; thus stability criteria derived for disks in rigid halos do not apply when the halo is responsive. The study presented here is of an idealized family of models with near uniform central rotation and that lack an extended halo; we present more realistic models with extended halos in a companion paper. The puzzle presented by the absence of strong bars in some galaxies having gently rising inner rotation curves is compounded by the results presented here.

ABSTRACT
We report the detection of a cold Neptune m
planet = 21 ± 2 M
⊕ orbiting a 0.38 M
⊙ M dwarf lying 2.5–3.3 kpc toward the Galactic center as part of a campaign combining ground-based and Spitzer observations to measure the Galactic distribution of planets. This is the first time that the complex real-time protocols described by Yee et al., which aim to maximize planet sensitivity while maintaining sample integrity, have been carried out in practice. Multiple survey and follow up teams successfully combined their efforts within the framework of these protocols to detect this planet. This is the second planet in the Spitzer Galactic distribution sample. Both are in the near to mid-disk and are clearly not in the Galactic bulge.
MAGNETIC FIELDS IN EARLY PROTOSTELLAR DISK FORMATION
Authors: González-Casanova Diego F. , Lazarian Alexander , Santos-Lima Reinaldo 
Published: March 2016

ABSTRACT
We consider formation of accretion disks from a realistically turbulent molecular gas using 3D MHD simulations. In particular, we analyze the effect of the fast turbulent reconnection described by the Lazarian & Vishniac model for the removal of magnetic flux from a disk. With our numerical simulations we demonstrate how the fast reconnection enables protostellar disk formation resolving the so-called “magnetic braking catastrophe.” In particular, we provide a detailed study of the dynamics of a 0.5 M
⊙ protostar and the formation of its disk for up to several thousands years. We measure the evolution of the mass, angular momentum, magnetic field, and turbulence around the star. We consider effects of two processes that strongly affect the magnetic transfer of angular momentum, both of which are based on turbulent reconnection: the first, “reconnection diffusion,” removes the magnetic flux from the disk; the other involves the change of the magnetic field's topology, but does not change the absolute value of the magnetic flux through the disk. We demonstrate that for the first mechanism, turbulence causes a magnetic flux transport outward from the inner disk to the ambient medium, thus decreasing the coupling of the disk to the ambient material. A similar effect is achieved through the change of the magnetic field's topology from a split monopole configuration to a dipole configuration. We explore how both mechanisms prevent the catastrophic loss of disk angular momentum and compare both above turbulent reconnection mechanisms with alternative mechanisms from the literature.
PROBING THE CARBON–PHOSPHORUS BOND COUPLING IN LOW-TEMPERATURE PHOSPHINE (PH3)–METHANE (CH4) INTERSTELLAR ICE ANALOGUES
Authors: Turner Andrew M. , Abplanalp Matthew J. , Kaiser Ralf I. 
Published: March 2016

ABSTRACT
Phosphine, which has now been confirmed around the carbon-rich star IRC+10216, provides the first example of a phosphorus-containing single bond in interstellar or circumstellar media. While four compounds containing both phosphorus and carbon have been discovered, none contain a carbon–phosphorus single bond. Here, we show that this moiety is plausible from the reaction of phosphine with methane in electron-irradiated interstellar ice analogues. Fractional sublimation allows for detection of individual products at distinct temperatures using reflectron time-of-flight mass spectrometry (ReTOF) coupled with vacuum ultraviolet photoionization. This method produced phosphanes and methylphosphanes as large as P8H10 and CH3P8H9, which demonstrates that a phosphorus–carbon bond can readily form and that methylphosphanes sublime at 12–17 K higher temperatures than the non-organic phosphanes. Also, irradiated ices of phosphine with deuterated-methane untangle the reaction pathways through which these methylphosphanes were formed and identified radical recombination to be preferred over carbene/phosphinidene insertion reactions. In addition, these ReTOF results confirm that CH3PH2 and CH6P2 can form via insertion of carbene and phosphinidene and that the methylenediphosphine (PH2CH2PH2) isomer forms in the ices, although methylphosphine (CH3P2H3) is likely the more abundant isomer and that phosphanes and organophosphanes preferentially fragment via the loss of a phosphino group when photoionized. While the formation of methylphosphine is overall endoergic, the intermediates produced by interactions with energetic electrons proceed toward methylphosphine favorably and barrierlessly and provide plausible mechanisms toward hitherto unidentified interstellar compounds.

ABSTRACT
RCW 86 is a young supernova remnant (SNR) showing a shell-type structure at several wavelengths and is thought to be an efficient cosmic-ray (CR) accelerator. Earlier Fermi Large Area Telescope results reported the detection of γ-ray emission coincident with the position of RCW 86 but its origin (leptonic or hadronic) remained unclear due to the poor statistics. Thanks to 6.5 years of data acquired by the Fermi-LAT and the new event reconstruction Pass 8, we report the significant detection of spatially extended emission coming from RCW 86. The spectrum is described by a power-law function with a very hard photon index (

) in the 0.1–500 GeV range and an energy flux above 100 MeV of (

)

erg cm−2 s−1. Gathering all the available multiwavelength (MWL) data, we perform a broadband modeling of the nonthermal emission of RCW 86 to constrain parameters of the nearby medium and bring new hints about the origin of the γ-ray emission. For the whole SNR, the modeling favors a leptonic scenario in the framework of a two-zone model with an average magnetic field of 10.2 ± 0.7 μG and a limit on the maximum energy injected into protons of 2 × 1049 erg for a density of 1 cm−3. In addition, parameter values are derived for the north–east and south–west (SW) regions of RCW 86, providing the first indication of a higher magnetic field in the SW region.
Checklist of aquatic and marshy Monocotyledons from the Araguaia River basin, Brazilian Cerrado
Authors: Oliveira Adriana , Bove Claudia 
Published: March 2016

The Araguaia River basin runs through the states of Goiás, Mato Grosso, Tocantins, and Pará, covering 373,000 Km2, mostly within the Brazilian Cerrado. The region has a wide variety of wetlands. The climate is characterized by high temperatures and strongly seasonal precipitation. There are two well defined seasons: the dry season (winter-spring) and the rainy season (summer- fall). The Araguaia River basin is dominated by plinthosoils that are found in low flat areas, poorly drained and prone to flooding, yielding wetland habitats of high plant diversity. Since the 1970s, human activities have led to reduction in both the diversity and area of wetlands. The construction of the Belém-Brasília highway and hydroelectric dams, as well as the expansion of agricultural and mining activities, have had major impacts on the region.
The flora diversity data of the Araguaia River basin was developed through field work, herbarium research, and use of a database (Species Link). The resulting checklist of 162 aquatic and marshy monocotyledons from the Araguaia River basin represents 20 families and 50 genera. Cyperaceae (51 spp.), Poaceae (39 spp.), and Eriocaulaceae (16 spp.) are the most representative families. Life form analysis indicates that helophytes predominate (98 spp.; 60.5%). One hundred one species are native to tropical and/or subtropical America and twenty one are endemic to Brazil. Ninety-three species are new occurrences for the Araguaia River basin. Among them, three species are reported in the Brazilian Cerrado for the first time. This work contributes to the understanding of aquatic plant diversity in the Cerrado and other savanna-like vegetation physiognomies; environments and habitats poorly understood taxonomically and undercollected generally.
Rotifers and lower crustaceans from South-western Iceland
Authors: Evtimova Vesela , Pandourski Ivan 
Published: March 2016

Iceland has high availability of freshwater, and it is rich in brackish and coastal aquatic bodies. However, knowledge on rotifers and meiobenthic and planktonic crustaceans inhabiting these habitats is lacking, and the inland aquatic fauna in Iceland is relatively understudied in comparison with the fauna of adjacent marine ecosystems. The majority of past research focused on larger lakes with the exception of one study on rotifers from the 1950s (Bartoš 1951) and two more recent studies on crustacean fauna of shallow freshwater bodies (Novichkova et al. 2014, Scher et al. 2000). Data are particularly scarce for the south-western part of the country.
We studied the composition of selected invertebrate taxa in various aquatic (marine, brackish and freshwater) habitats from South-western Iceland with a focus on Rotifera, Cladocera and Copepoda. Samples were collected from 12 localities, including marine interstitial, freshwater temporary shallow pools, swamps, wet mosses, springs, and lakes (both brackish and freshwater). We found 39 taxa in total. Rotifera dominated the sampled water bodies, followed by Copepoda and Cladocera. Three of the recorded taxa are new for Iceland, of which two are rotifers [Trichocerca cf. mucosa (Stokes, 1896) and T. vernalis (Hauer, 1936)], and one is a marine copepod (Cyclopina gracilis Claus, 1862). For some of the sampled localities (Sikið and Leirvogsvatn Lakes, and some of the smaller habitats) we present the first data on their microinvertebrate fauna.

Objective.To assess vascular endothelial growth factor (VEGF) correlations with new bone formation and bone marrow edema in patients with ankylosing spondylitis (AS) treated with golimumab (GOL).Methods.Following placebo control (through weeks 16 and 24), GO-RAISE (A Multicenter Randomized, Double-blind, Placebo-controlled Trial of Golimumab, a Fully Human Anti-TNF-α Monoclonal Antibody, Administered Subcutaneously, in Subjects with Active Ankylosing Spondylitis; ClinicalTrials.gov: NCT00265083) all patients received GOL; sera/images were available at weeks 0, 104, and 208. Lateral spinal radiographs and magnetic resonance imaging (MRI) were scored using the modified Stokes Ankylosing Spondylitis Spine Score (mSASSS) and the Ankylosing Spondylitis Spinal MRI activity score, respectively.Results.VEGF levels and the mSASSS did not significantly correlate. Logistic regression analyses showed no association between VEGF levels and an increased risk of syndesmophyte formation at weeks 104 and 208. Pretreatment/Week 14 VEGF did not predict MRI scores/changes at Week 104.Conclusion.Serum VEGF did not predict radiographic progression/spinal inflammation in patients receiving antitumor necrosis factor.
Représentations sociales des sans-abri. La mobilisation des Enfants de Don Quichotte à Paris
Authors: Colombo Annamaria , Pulzer Noémie , Parazelli Michel 
Published: March 2016

La mobilisation des Enfants de Don Quichotte en hiver 2006-2007 visait à attirer l’attention politique et citoyenne sur les conditions des sans-abri à Paris. De par son caractère inhabituel, cette mobilisation a bouleversé les rapports entre les acteurs concernés par la question du sans-abrisme et du mal-logement à Paris et entraîné une reconfiguration de la prise en charge de ces populations. Sans nier les effets de cette mobilisation sur la prise en charge des sans-abri en France, cet article s’intéresse plutôt aux représentations des sans-abri et aux modalités de l’action à leur égard que l’analyse de ce « cas d’étude » permet de révéler.
Le mouvement abolitionniste français dans l’après-guerre
Authors: Mathieu Lilian 
Published: March 2016

Relativement mal connue, la période 1946-1960 est importante dans l’histoire du mouvement français pour l’abolition de la réglementation de la prostitution. Cette séquence ne donne pas seulement lieu à une lutte pour la suppression, après la fermeture des maisons closes, du fichier médico-social obligatoire des prostituées. Elle est surtout celle d’un effacement des courants abolitionnistes historiques, liés à la bourgeoisie protestante et dont le discours associe traite des blanches et réglementarisme, au profit d’une mouvance nouvelle, issue du catholicisme social et promotrice d’une approche davantage sociale du phénomène prostitutionnel. C’est à cette mouvance, principalement incarnée par le Nid, que la conversion de la France à l’abolitionnisme va donner les moyens de prospérer à partir de 1960.
Manuel de direction en action sociale et médico-sociale
Authors: Lafore Robert

Les associations présentes dans le champ de l'action sociale vivent une tension qui est allée en s'exacerbant : précédant largement l'intervention publique et procédant d'initiatives plurielles et évolutives, la forme associative a abrité et rendu possible une appréhension de la société civile par elle-même, jouant ainsi le rôle de médiation collective entre les difficultés sociales vécues par les individus et leur émergence sur la scène du politique ; mais dans l'autre sens, devant mettre en ordre toutes ces initiatives pour leur donner une certaine cohérence dans le cadre des politiques sociales au moment de leur développement, la puissance publique a imposé tout un arsenal de sujétions et de contrôles pesant sur les activités des associations. Alors que cette tension, essentiellement par le truchement de corporations professionnelles qui liaient logique de la vocation et constructions scientifico-techniques des interventions, a pu trouver un équilibre gardant aux associations leur rôle médiateur, les mutations légales et réglementaires contemporaines mettent en cause aujourd'hui leur fonction de médiation collective. Cette situation, qui met logiquement les associations en difficultés, doit susciter une remobilisation autour de leur substance propre d'une part et d'autre part la construction d'un nouveau pacte avec la puissance publique.

Le monde contemporain des directeurs du secteur social et médico-social, à dominante associative, reste traversé par de nombreuses tensions et contradictions. Dans ce chapitre, l'auteur propose d'abord une classification idéal-typique des différentes figures de directeur qu'il a pu observer. Puis il explore quelques hypothèses contextuelles et institutionnelles pour expliquer la tension majeure qu'il décèle entre le directeur dirigeant et le directeur manageant. Enfin, sous le titre « Questions vives », il s'interroge sur le sens du renforcement de la verticalité, sur la place de l'évaluation qu'il qualifie de « troisième directeur » et sur le problème de la taille des structures.
Manuel de direction en action sociale et médico-sociale
Authors: Jaeger Marcel 
Published: March 2016

L'évaluation est une question centrale, objet de conflits et de résistances, qui oblige les cadres de direction à se préparer à deux challenges : surmonter les résistances des professionnels, y compris les leurs ; construire des stratégies pour mettre en place les procédures d'évaluation interne et d'évaluation externe telles qu'elles ont été voulues par le législateur. Cela nécessite une pédagogie de l'évaluation qui illustre une des dimensions d'avenir de la fonction de direction. En même temps, il s'agit de restituer la philosophie de l'évaluation, dont l'axe central est la réaffirmation de la place prééminente de l'usager, avant d'aborder les aspects plus pratiques de la procédure évaluative, les choix méthodologiques, les modalités techniques.

Le titre de ce texte Ina mè skandalisthêté « Afin que vous ne trébuchiez pas » est volontairement provocant : en partant des problématiques douloureuses des entreprises contemporaines, des troubles qui traversent la gestion du personnel, de la crise des valeurs axées essentiellement sur la rentabilité, le profit et la performance, il met en question l'idée qui traverse actuellement, l'esprit de bon nombre de responsables de l'administration selon lequel l'entreprise devrait être le nouveau paradigme du social. Aussi ne faut-il pas « trébucher », et inverser le regard en rappelant les valeurs fondamentalement humanistes du champ social devrait plutôt servir de modèle à l'entreprise pour qu'elle puisse redonner toute sa place à l'être humain. L'axiologie spécifique au champ social (éthique, héritage, politique comme changement des places) entraîne un nouveau regard sur le métier de directeur qui ne le réduit pas à des fonctions de gestion, de maîtrise et de contrôle mais l'ouvre à la « vertu » et à l'art de saisir l'occasion ( kaïros ).
Reconnaître les « zones grises » de l’observation : du trouble à la vigilance ethnographique
Authors: Namian Dahlia , Grimard Carolyne 
Published: March 2016

La pratique de l’observation est balisée par un certain nombre de procédés méthodologiques qui permettent à tout chercheur prudent de préparer et contrôler un tant soit peu les paramètres de sa recherche. Or cette méthode est traversée en parallèle de « zones grises » qui, tout en mettant à l’épreuve le cadre « raisonnable » de ces procédés, laissent entrevoir des troubles ou des enjeux face auxquels les chercheurs font preuve de vigilance réflexive et s’engagent à maintenir une cohérence dans leur démarche d’enquête. Sur la base d’exemples tirés d’enquêtes, en anthropologie et en sociologie, et de nos propres démarches d’observation, nous discuterons plus spécifiquement de ces zones grises de l’observation via une typologie détaillant trois enjeux qui sont des occasions de trouble : la délimitation, la distanciation et l’identification. Sans être exhaustive, cette typologie attire l’attention sur les dimensions spatiales (tant géographiques, subjectives que sociales) de l’observation.
