Abstract
The orbits, atmospheric parameters, chemical abundances, and ages of individual stars in the Milky Way provide the most comprehensive illustration of galaxy formation available. The Tycho-Gaia Astrometric Solution (TGAS) will deliver astrometric parameters for the largest ever sample of Milky Way stars, though its full potential cannot be realized without the addition of complementary spectroscopy. Among existing spectroscopic surveys, the RAdial Velocity Experiment (RAVE) has the largest overlap with TGAS (≳200,000 stars). We present a data-driven re-analysis of 520,781 RAVE spectra using The Cannon. For red giants, we build our model using high-fidelity APOGEE stellar parameters and abundances for stars that overlap with RAVE. For main sequence and sub-giant stars, our model uses stellar parameters from the K2/EPIC. We derive and validate effective temperature T
eff, surface gravity log g, and chemical abundances of up to seven elements (O, Mg, Al, Si, Ca, Fe, and Ni). We report a total of 1,685,851 elemental abundances with a typical precision of 0.07 dex, a substantial improvement over previous RAVE data releases. The synthesis of RAVE-on and TGAS is the most powerful data set for chemo-dynamic analyses of the Milky Way ever produced.

Abstract
We study the disk–jet connection in supermassive black holes by investigating the properties of their optical and radio emissions utilizing the SDSS DR7 and the NVSS catalogs. Our sample contains 7017 radio-loud quasars with detection both at 1.4 GHz and SDSS optical spectra. Using this radio-loud quasar sample, we investigate the correlation among the jet power (

Radiative Transfer in a Translucent Cloud Illuminated by an Extended Background Source
Authors: Biganzoli Davide , Potenza Marco A. C. , Robberto Massimo 
Published: May 2017

Abstract
We discuss the radiative transfer theory for translucent clouds illuminated by an extended background source. First, we derive a rigorous solution based on the assumption that multiple scatterings produce an isotropic flux. Then we derive a more manageable analytic approximation showing that it nicely matches the results of the rigorous approach. To validate our model, we compare our predictions with accurate laboratory measurements for various types of well-characterized grains, including purely dielectric and strongly absorbing materials representative of astronomical icy and metallic grains, respectively, finding excellent agreement without the need to add free parameters. We use our model to explore the behavior of an astrophysical cloud illuminated by a diffuse source with dust grains having parameters typical of the classic ISM grains of Draine & Lee and protoplanetary disks, with an application to the dark silhouette disk 114–426 in Orion Nebula. We find that the scattering term modifies the transmitted radiation, both in terms of intensity (extinction) and shape (reddening) of the spectral distribution. In particular, for small optical thickness, our results show that scattering makes reddening almost negligible at visible wavelengths. Once the optical thickness increases enough and the probability of scattering events becomes close to or larger than 1, reddening becomes present but is appreciably modified with respect to the standard expression for line-of-sight absorption. Moreover, variations of the grain refractive index, in particular the amount of absorption, also play an important role in changing the shape of the spectral transmission curve, with dielectric grains showing the minimum amount of reddening.
Post-Newtonian Dynamical Modeling of Supermassive Black Holes in Galactic-scale Simulations
Authors: Rantala Antti , Pihajoki Pauli , Johansson Peter H. , Naab Thorsten , Lahén Natalia , Sawala Till 
Published: May 2017

Abstract
We present KETJU, a new extension of the widely used smoothed particle hydrodynamics simulation code GADGET-3. The key feature of the code is the inclusion of algorithmically regularized regions around every supermassive black hole (SMBH). This allows for simultaneously following global galactic-scale dynamical and astrophysical processes, while solving the dynamics of SMBHs, SMBH binaries, and surrounding stellar systems at subparsec scales. The KETJU code includes post-Newtonian terms in the equations of motions of the SMBHs, which enables a new SMBH merger criterion based on the gravitational wave coalescence timescale, pushing the merger separation of SMBHs down to ∼0.005 pc. We test the performance of our code by comparison to NBODY7 and rVINE. We set up dynamically stable multicomponent merger progenitor galaxies to study the SMBH binary evolution during galaxy mergers. In our simulation sample the SMBH binaries do not suffer from the final-parsec problem, which we attribute to the nonspherical shape of the merger remnants. For bulge-only models, the hardening rate decreases with increasing resolution, whereas for models that in addition include massive dark matter halos, the SMBH binary hardening rate becomes practically independent of the mass resolution of the stellar bulge. The SMBHs coalesce on average 200 Myr after the formation of the SMBH binary. However, small differences in the initial SMBH binary eccentricities can result in large differences in the SMBH coalescence times. Finally, we discuss the future prospects of KETJU, which allows for a straightforward inclusion of gas physics in the simulations.
Herschel Spectroscopy of Early-type Galaxies
Authors: Lapham Ryen Carl , Young Lisa M. , Crocker Alison 
Published: May 2017

Abstract
We present Herschel spectroscopy of atomic lines arising in photodissociation regions as well as ionization regions of nearby early-type galaxies (ETGs), focusing on the volume-limited Atlas3D sample. Our data include the [C ii], [O i], and [N ii] 122 and 205 μm lines, along with ancillary data including CO and H i maps. We find that ETGs have [C ii]/FIR ratios slightly lower than spiral galaxies in the KINGFISH sample, and several ETGs have unusually large [N ii] 122/[C ii] ratios. The [N ii] 122/[C ii] ratio is correlated with UV colors and there is a strong anti-correlation of [C ii]/FIR with NUV-K seen in both spirals and ETGs, likely due to a softer radiation field with fewer photons available to ionize carbon and heat the gas. The correlation thus makes a [C ii] deficit in galaxies with redder stellar populations. The high [N ii] 122/[C ii] (and low [C ii]/FIR) line ratios could also be affected by the removal of much of the diffuse, low-density gas, which is consistent with the low H i/H2 ratios. [C ii] is now being used as a star-formation indicator, and we find that it is just as good for ETGs as in spirals. The [C ii]/CO ratios found are also similar to those found in spiral galaxies. Through the use of the [N ii] 205 μm line, estimates of the percentage of [C ii] emission arising from ionized gas indicate that a significant portion could arise in ionized regions.
L’université de Caen dans la cité, 1944-1957
Authors: Hamelin Bertrand 
Published: May 2017

Pourquoi une université ? Une université pour quoi faire ? Telles sont les deux principales questions posées après la destruction de l’université de Caen en 1944. Sur le premier point, la reconstruction d’une université à Caen apparaît immédiatement comme une condition impérative au relèvement de la cité, soucieuse de maintenir et de développer ses fonctions métropolitaines aux échelles régionale, nationale et même internationale. Sur le second point, la reconstruction est le moment d’une interrogation générale sur les missions de l’université, qui évoluent alors de manière sensible. Aux participations planifiées de l’université à la vie de la cité (expertise et contribution au développement économique régional notamment), s’ajoutent rapidement des implications non anticipées : universitaires et étudiants deviennent en quelques années des acteurs centraux du champ politique et social caennais.
Essai d’évaluation de la production philosophique contemporaine
Authors: Citot Vincent 
Published: May 2017

Qu’est-ce qu’une grande philosophie et comment évaluer une œuvre philosophique ? Qu’est-ce qu’une période philosophiquement brillante, et selon quels critères en juger ? Pour y répondre, il faut poser à nouveaux frais la question de la définition de la philosophie, et identifier les exigences fondamentales de la pensée philosophique. Tel est l’objet de la première partie. La seconde tire de ces considérations une méthode pour cartographier et évaluer la philosophie contemporaine. Il en ressort qu’elle ne satisfait pas les exigences les plus essentielles de la philosophie.
La psychanalyse dans la culture russe
Authors: Loukomskaïa Marina 
Published: May 2017

Pour mieux comprendre les liens étroits entre psychanalyse et culture russe d’aujourd’hui, il faut rappeler les conditions dans lesquelles la psychanalyse s’est développée en Russie. Au début du xx	e siècle, la situation était favorable à la diffusion des idées freudiennes, et la Russie est devenue le premier pays à prendre en compte la ­psychanalyse en dehors de la culture germanique où elle née. Mais après ces débuts précoces, la psychanalyse a été attaquée par les bolcheviques et définitivement interdite sous Staline. La libéralisation progressive de la Russie a permis le redéploiement de ­l’espace privé absorbé par l’Etat totalitaire. La psychanalyse russe est aujourd’hui en pleine renaissance et largement présente dans tous les domaines culturels.
L’ombre portée de l’inquiétante étrangeté
Authors: Massin Marianne 
Published: May 2017

En amont, l’idée d’inquiétante étrangeté procède de la culture de Freud, de sa culture de la langue et de la littérature ; en aval, elle irrigue la culture contemporaine non sans distorsions ou écarts. Cet article s’interroge sur cette réversibilité causale, l’art inspire la psychanalyse qui inspire l’art, et sur l’extension impressionnante – et peut-être parfois contestable – du concept dans l’art contemporain. L’hypothèse défendue est qu’il y aurait là ce qu’on se risquera à appeler une « ombre portée » du texte freudien.
Une rencontre avec François Jullien

Published: May 2017

Le philosophe et sinologue François Jullien expose comment sa stratégie de détour par la Chine permet de révéler l’impensé de la pensée européenne (causalité, liberté, interprétation), ce que vise aussi à sa manière la psychanalyse. Il décrit ensuite ce que sont pour lui les forces et les faiblesses celle-ci, afin de préserver le vif de son apport : sa capacité d’ébranlement de notre culture.
De quelques usages de la psychanalyse en éducation et formation
Authors: Fersing Éliane , Ployé Alexandre , Delarue-Breton Catherine 
Published: May 2017

La place de la psychanalyse dans la recherche sur l’éducation comme dans les pratiques de formation des enseignants peut sembler aujourd’hui relativement modeste. Pourtant, son rôle pourrait être qualifié à la fois de marginal et d’incontournable. À l’écoute des non-dits et sensible aux failles, la psychanalyse reste un éclairage nécessaire de cette activité sans fin et sans garantie qu’est l’éducation, toujours menacée par la tentation techniciste et l’illusion de la maîtrise.
Sur le texte de Jacques Press : « Enjeux épistémologiques et cliniques de la recherche en psychosomatique »
Authors: Aisenstein Marilia 
Published: May 2017

Discutant le texte de Jacques Press, l’auteur souligne un accord profond sur la clinique et la technique face à des patients complexes dont la souffrance est extrême. Elle considère comme très intéressante l’hypothèse de J. Press qui voit la désorganisation somatique comme une solution devant la menace d’effondrement et pense la voie somatique comme « solution ». Elle s’oppose néanmoins à l’idée selon laquelle Pierre Marty se serait situé plutôt comme un observateur du patient somatique et s’appuie pour ce faire sur l’article princeps de ce dernier : « Les difficultés narcissiques de l’observateur devant le problème psychosomatique », texte qui porte, d’après elle, sur le contretransfert et sur une forme particulière d’identification projective.
L’industrie du phosphate de Taïba au Sénégal : front minier et tensions locales
Authors: Diallo Mouhamadou Lamine 
Published: May 2017

L’expansion des carrières d’exploitation du phosphate dans la région de Thiès, à l’ouest du Sénégal, est source de reconfiguration territoriale et de tensions liées à l’utilisation des ressources naturelles. L’avancée du front minier sur les espaces agricoles et le déplacement des villages amènent la population riveraine à s’organiser et à développer des stratégies pour faire face aux impacts des activités extractives. Ainsi, l’article se propose d’analyser ces dynamiques territoriales à partir du site d’extraction du phosphate de Taïba dans la région de Thiès. Il s’articule autour de deux points : montrer les implications spatiales et environnementales de l’exploitation du phosphate, puis analyser les tensions entre la compagnie minière, les Industries chimiques du Sénégal et les communautés locales.
Protein Kinase CK2 Controls the Fate between Th17 Cell and Regulatory T Cell Differentiation
Authors: Gibson Sara A. , Yang Wei , Yan Zhaoqi , Liu Yudong , Rowse Amber L. , Weinmann Amy S. , Qin Hongwei , Benveniste Etty N. 
Published: May 2017

Abstract
CK2 is a highly conserved and pleiotropic serine/threonine kinase that promotes many prosurvival and proinflammatory signaling pathways, including PI3K/Akt/mTOR and JAK/STAT. These pathways are essential for CD4+ T cell activation and polarization, but little is known about how CK2 functions in T cells. In this article, we demonstrate that CK2 expression and kinase activity are induced upon CD4+ T cell activation. Targeting the catalytic activity of CK2 using the next-generation small molecule inhibitor CX-4945 in vitro significantly and specifically inhibited mouse and human Th17 cell differentiation while promoting the generation of Foxp3+ regulatory T cells (Tregs). These findings were associated with suppression of PI3K/Akt/mTOR activation and STAT3 phosphorylation upon CX-4945 treatment. Furthermore, we demonstrate that CX-4945 treatment inhibits the maturation of Th17 cells into inflammatory IFN-γ–coproducing effector cells. The Th17/Treg axis and maturation of Th17 cells are major contributing factors to the pathogenesis of many autoimmune disorders, including multiple sclerosis. Using a murine model of multiple sclerosis, experimental autoimmune encephalomyelitis, we demonstrate that in vivo administration of CX-4945 targets Akt/mTOR signaling in CD4+ T cells and the Th17/Treg axis throughout disease. Importantly, CX-4945 treatment after disease initiation significantly reduced disease severity, which was associated with a significant decrease in the frequency of pathogenic IFN-γ+ and GM-CSF+ Th17 cells in the CNS. Our data implicate CK2 as a regulator of the Th17/Treg axis and Th17 cell maturation and suggest that CK2 could be targeted for the treatment of Th17 cell–driven autoimmune disorders.
Alcoholic Beverage and Traffic Accidents: Impact of the Drunk-Driving Law in Severity and Mortality of Victims
Authors: de S Nogueira Lilia , de A Domingues Cristiane , Bonfim Ane KS 
Published: May 2017

ABSTRACT
Objectives
To analyze the impact of the Drunk-Driving Law on the characteristics and severity of traffic accident victims and to identify risk factors for mortality before and after law enforcement.

Materials and methods
A retrospective, quantitative study that analyzed victims of traffic accidents attended at a hospital in São Paulo, Brazil, between 2006 and 2010, through the analysis of medical records. The Drunk-Driving Law was considered the time frame of this research, and the victims were distributed in two groups: Before the law (January 2006 to June 2008) and after the law (July 2008 to December 2010). Pearson chi-square, Mann–Whitney, and multiple logistic regression tests were used, with a significance level of 5%.

Results
The sample consisted of 1,405 victims, the majority being males (78.01%), with a mean age of 37.39 years. In the group comparison (before and after the Drunk-Driving Law), there was a significant difference related to the external cause, admission to the ICU, and discharge conditions. Factors associated with prelaw mortality were age, number of injured body regions, and New Injury Severity Score. The length of hospital stay and the Revised Trauma Score were considered as protective factors for this outcome. After the validity of the law, in addition to the variables described earlier, the head/neck and abdomen regions most severely injured were added as risk factors for mortality.

Conclusion
The impact of the Drunk-Driving Law set a positive outcome in the survival of the victims. However, when it comes to the statistics and severity of the trauma, it is necessary to sustain the law with reinforcement of the inspection so that more lives are saved.

Clinical significance
The results of this study provide support to managers on the importance of sustaining the law and the need of implementing new trauma prevention strategies.

Unstable Chest Surgical Management in Pregnancy: Case Report and Literature Review
Authors: Velásquez Mauricio , Escobar María F , Carvajal Javier A , Nieto Albaro J 
Published: May 2017

ABSTRACT
Introduction
We present a review of the case, management, and progress of an obstetric patient, who suffered a car accident with subsequent severe blunt thoracic trauma (BTT) resulting in flail chest (FC).

Case report
This is a Hispanic female of 44 years involved in a car accident at 14 weeks of gestation, who presented with FC, sternal fracture, and severe respiratory compromise. This woman received surgical management and care in an intensive obstetric care management unit, presenting with osteomyelitis as a complication, along with physical deconditioning and prolonged hospital stay, finally with an obstetric and functional favorable outcome.

Conclusion
Although severe BTT in pregnant patients is uncommon, it is important to highlight the appropriate medical management required for these patients to achieve a successful outcome, as was in this case. This is the only case report of a FC surgical management in pregnancy that we have had in our institution so far.

Dandy–Walker Syndrome: Management at Acharya Vinoba Bhave Rural Hospital, Wardha, India
Authors: Jabbal Harmandeep , Wagh Dhirendra 
Published: May 2017

AbstractWe discuss 10 cases of Dandy–Walker syndrome that presented between May 2014 and June 2015 at the Department of Neurosurgery and General Surgery in Acharya Vinoba Bhave Rural Hospital, Sawangi (M), Wardha, India. As the definitive surgical treatment protocol is not standardized, we discuss the different techniques used. Combined cystoperitoneal (CP) and ventriculoperitoneal (VP) shunt was done in three cases, two were treated with CP shunt alone, and the remaining five cases were managed with VP shunt.Follow-up showed marked reduction in the head circumference and better motor development, along with alleviation of other neurological symptoms.Seizures, hearing or visual problems, various central nervous system abnormalities, and systemic abnormalities were associated with poor intellectual development and could be used to predict intellectual outcome.Prognosis varies due to several factors, but an early diagnosis and appropriate treatment have a good prognostic value.
Prevalence of Myopia and its Risk Factors in Rural Schoolchildren
Authors: Kher Praveena , Patel Pavitra 
Published: May 2017

Abstract
Introduction: Myopia, also known as short sightedness, is a type of refractive error in which parallel rays coming from infinity are focused in front of the retina when accommodation is at rest. It is a condition in which close objects are seen clearly, but objects farther away appear blurred. It is an ophthalmic condition affecting 30% population. It is commonly seen in schoolchildren aged 8 to 12 years. This study was undertaken to find the prevalence of myopia among students aged 5 to 16 years of a school in a rural area of Wardha, Maharashtra, India.
Materials and methods: Study sample included children between 5 and 16 years of age from a nearby rural school. We recorded degree of myopia by autorefractometer, and students with refractive error of <-0.5 D for at least one eye were considered as myopic. Strict inclusion and exclusion criteria were followed.
Results: It was found that the prevalence of myopia is 39.6%. Mild to moderate degree of myopia was more common than severe one. Among the 198 myopic students, 112 were females and 86 were males. We found that there was no significant correlation between family history and presence of myopia. But, unhealthy reading habits and playing games on computer for 1 to 2 hours have an influence in the development of myopia.
Conclusion: Due to high magnitude of uncorrected myopia, it appears to be a public health problem both in urban and rural areas, which suggest that an increase in outdoor activity may help to reduce the magnitude of the problem. Schoolteachers should be involved for positive reinforcement of schoolchildren for screening.
Charlie Chaplin di Ngamplang, 1927 / Charlie Chaplin at Ngamplang, 1927
Authors: Campbell Ian 
Published: May 2017

‘Charlie Chaplin di Ngamplang, 1927’ is an Indonesian-language poem by Australian poet Ian Campbell, and is a humorous meditation upon certain imaginary events that befell Charlie Chaplin at the Dutch colonial era hill station of Ngamplang in West Java in 1927. In historical terms Chaplin did in fact visit the Dutch East Indies three times between 1927 and 1932, including the area around Ngamplang. The poem was included in Campbell’s poetry and prose collection Tak ada Peringatan (Vivid Publishing, 2013). The Indonesian language version of the poem first appeared in 2012 in the literary pages of the Jakarta mass media daily Kompas. An English-language back translation is included here.
