OBJECTIVE
The objective of this study was to review clinical outcomes following resection of giant spinal schwannomas.

METHODS
The authors conducted a retrospective review of a case series of patients with giant spinal schwannomas at a tertiary cancer hospital.

RESULTS
Thirty-two patients with giant spinal schwannomas underwent surgery between September 1998 and May 2013. Tumor size ranged from 2.5 cm to 14.6 cm with a median size of 5.8 cm. There were 9 females (28.1%) and 23 males (71.9%), and the median age was 47 years (range 23–83 years). The median follow-up duration was 36.0 months (range 12.2–132.4 months). Three patients (9.4%) experienced recurrence and required further treatment. All recurrences developed following subtotal resection (STR) of cellular or melanotic schwannoma. There were 3 melanotic (9.4%) and 6 cellular (18.8%) schwannomas included in this study. Among these histological variants, a 33.3% recurrence rate was noted. In 1 case of melanotic schwannoma, malignant transformation occurred. No recurrence occurred following gross-total resection (GTR) or when a fibrous capsule remained due to its adherence to functional nerve roots.

CONCLUSIONS
Resection is the treatment of choice for symptomatic or growing giant schwannomas, frequently requiring anterior or combined approaches, with the goals of symptom relief and prevention of recurrence. In this series, tumors that underwent GTR, or where only capsule remained, did not recur. Only melanotic and cellular schwannomas that underwent STR recurred.
PRESSURE PULSES AT VOYAGER 2: DRIVERS OF INTERSTELLAR TRANSIENTS?

ABSTRACT

Voyager 1 (V1) crossed the heliopause into the local interstellar medium (LISM) in 2012. The LISM is a dynamic region periodically disturbed by solar transients with outward-propagating shocks, cosmic-ray intensity changes and anisotropies, and plasma wave oscillations. Voyager 2 (V2) trails V1 and thus may observe the solar transients that are later observed at V1. V2 crossed the termination shock in 2007 and is now in the heliosheath. Starting in 2012, when solar maximum conditions reached V2, five possible merged interaction regions (MIRs) have been observed by V2 in the heliosheath. The timing is consistent with these MIRs driving the transients observed by V1 in the LISM. The largest heliosheath MIR was observed by V2 in late 2015 and should reach V1 in 2018.

ABSTRACT
We report new observations from a systematic, spectroscopic, ultraviolet absorption-line survey that maps the spatial and kinematic properties of the high velocity gas in the Galactic Center (GC) region. We examine the hypothesis that this gas traces the biconical nuclear outflow. We use an ultraviolet spectra of 47 background QSOs and halo stars projected inside and outside the northern Fermi Bubble from the Hubble Space Telescope to study the incidence of high velocity absorption around it. We use five lines of sight inside the northern Fermi Bubble to constrain the velocity and column densities of outflowing gas traced by O i, Al ii, C ii, C iv, Si ii, Si iii, Si iv, and other species. We find that all five lines of sight inside the northern Fermi Bubble exhibit blueshifted high velocity absorption components, whereas only 9 out of the 42 lines of sight outside the northern Fermi Bubble exhibit blueshifted high velocity absorption components. The observed outflow velocity profile decreases with Galactic latitude and radial distance (R) from the GC. The observed blueshifted velocities change from

at R ≈ 2.3 kpc to

at R ≈ 6.5 kpc. We derive the metallicity of the entrained gas along the 1H1613-097 sightline, one that passes through the center of the northern Fermi Bubble, finding [O/H] ≳ −0.54 ± 0.15. A simple kinematic model, tuned to match the observed absorption component velocities along the five lines of sight inside the Bubble, constrains the outflow velocities to ≈1000–1300

, and the age of the outflow to be ∼6–9 Myr. We estimate a minimum mass outflow rate for the nuclear outflow to be

. Combining the age and mass outflow rates, we determine a minimum mass of total UV-absorbing cool gas entrained in the Fermi Bubbles to be

ON THE NEWTONIAN AND SPIN-INDUCED PERTURBATIONS FELT BY THE STARS ORBITING AROUND THE MASSIVE BLACK HOLE IN THE GALACTIC CENTER
Authors: Zhang Fupeng , Iorio Lorenzo 
Published: January 2017

ABSTRACT
The S-stars discovered in the Galactic center are expected to provide unique dynamical tests of the Kerr metric of the massive black hole (MBH) that they orbit. In order to obtain unbiased measurements of its spin and the related relativistic effects, a comprehensive understanding of the gravitational perturbations of the stars and stellar remnants around the MBH is quite essential. Here, we study the perturbations on the observables of a typical target star, i.e., the apparent orbital motion and the redshift, due to both the spin-induced relativistic effects and the Newtonian attractions of a single object or a cluster of disturbing objects. We find that, in most cases, the Newtonian perturbations on the observables are mainly attributed to the perturbed orbital period of the target star rather than the Newtonian orbital precessions. Looking at the currently detected star S2/S0-2, we find that its spin-induced effects are very likely obscured by the gravitational perturbations from the star S0-102 alone. We also investigate and discuss the Newtonian perturbations on a hypothetical S-star located inside the orbits of those currently detected. By considering a number of possible stellar distributions near the central MBH, we find that the spin-induced effects on the apparent position and redshift dominate over the stellar perturbations for target stars with orbital semimajor axis smaller than 100–400 au if the MBH is maximally spinning. Our results suggest that, in principle, the stellar perturbations can be removed because they have morphologies distinct from those of the relativistic Kerr-type signatures.
ARE FAST RADIO BURSTS THE BIRTHMARK OF MAGNETARS?
Authors: Lieu Richard 
Published: January 2017

ABSTRACT
A model of fast radio bursts, which enlists young, short period extragalactic magnetars satisfying B/P > 2 × 1016 G s−1 (1 G = 1 statvolt cm−1) as the source, is proposed. When the parallel component

of the surface electric field (under the scenario of a vacuum magnetosphere) of such pulsars approaches 5% of the critical field

, in strength, the field can readily decay via the Schwinger mechanism into electron–positron pairs, the back reaction of which causes

to oscillate on a characteristic timescale smaller than the development of a spark gap. Thus, under this scenario, the open field line region of the pulsar magnetosphere is controlled by Schwinger pairs, and their large creation and acceleration rates enable the escaping pairs to coherently emit radio waves directly from the polar cap. The majority of the energy is emitted at frequencies

where the coherent radiation has the highest yield, at a rate large enough to cause the magnetar to lose spin significantly over a timescale

a few

s, the duration of a fast radio burst. Owing to the circumstellar environment of a young magnetar, however, the ≲1 GHz radiation is likely to be absorbed or reflected by the overlying matter. It is shown that the brightness of the remaining (observable) frequencies of

and above are on a par with a typical fast radio burst. Unless some spin-up mechanism is available to recover the original high rotation rate that triggered the Schwinger mechanism, the fast radio burst will not be repeated again in the same magnetar.
SYNTHETIC OBSERVATIONS OF MAGNETIC FIELDS IN PROTOSTELLAR CORES
Authors: Lee Joyce W. Y. , Hull Charles L. H. , Offner Stella S. R. 
Published: January 2017

ABSTRACT
The role of magnetic fields in the early stages of star formation is not well constrained. In order to discriminate between different star formation models, we analyze 3D magnetohydrodynamic simulations of low-mass cores and explore the correlation between magnetic field orientation and outflow orientation over time. We produce synthetic observations of dust polarization at resolutions comparable to millimeter-wave dust polarization maps observed by the Combined Array for Research in Millimeter-wave Astronomy and compare these with 2D visualizations of projected magnetic field and column density. Cumulative distribution functions of the projected angle between the magnetic field and outflow show different degrees of alignment in simulations with differing mass-to-flux ratios. The distribution function for the less magnetized core agrees with observations finding random alignment between outflow and field orientations, while the more magnetized core exhibits stronger alignment. We find that fractional polarization increases when the system is viewed such that the magnetic field is close to the plane of the sky, and the values of fractional polarization are consistent with observational measurements. The simulation outflow, which reflects the underlying angular momentum of the accreted gas, changes direction significantly over over the first ∼0.1 Myr of evolution. This movement could lead to the observed random alignment between outflows and the magnetic fields in protostellar cores.
La fécondité au Canada durant le baby-boom . Divergence et convergence des comportements
Authors: Gauvreau Danielle , Laplante Benoît 
Published: January 2017

Au Canada, le baby-boom ne s’est pas déroulé de la même manière dans toutes les provinces. En particulier, l’Ontario et le Québec, les deux provinces les plus peuplées, ont connu des baby-booms très différents. En Ontario, le baby-boom s’est déroulé de manière conventionnelle : l’augmentation de la nuptialité et celle de la fécondité des femmes mariées ont contribué toutes deux à l’augmentation des indicateurs de fécondité. Au Québec, le baby-boom a eu lieu alors que la fécondité des femmes mariées diminuait encore, la nuptialité étant le plus important facteur de l’accroissement du nombre des naissances. Nous utilisons deux informations rétrospectives recueillies au recensement de 1981, l’âge au premier mariage et le nombre des enfants mis au monde, pour étudier la descendance finale et estimer les probabilités d’agrandissement de la famille des femmes nées entre 1900 et 1940. Nous utilisons la régression logistique multinomiale pour estimer l’effet de la religion, de l’origine ethnique, de l’éducation et de la province de résidence sur la descendance finale de ces femmes, en tenant compte de l’âge au mariage et de sa durée. Les résultats montrent que 1) la fécondité des catholiques et des protestantes, très éloignées au début du baby-boom , sont très semblables à la fin ; 2) l’avancement de l’âge au mariage et l’allongement de la durée du mariage augmentent la fécondité, mais cet effet de la nuptialité ne suffit pas à expliquer l’accroissement de la fécondité des protestantes ; 3) l’écart entre les niveaux d’éducation se rétrécit du début à la fin du baby-boom , mais ne disparaît pas entièrement. Ces résultats sont dans l’ensemble proches de ceux que des analyses plus fines ont récemment mis au jour dans des pays européens.
Symétries et asymétries de pouvoir dans les relations interculturelles en entreprises multinationales
Authors: Barmeyer Christoph 
Published: January 2017

Est-il possible de faire du management interculturel un sujet d’analyse par le biais d’autres formes de représentations que celles des langages écrit ou parlé ? Pourrions-nous privilégier des formes se concentrant essentiellement sur des éléments à forte charge émotionnelle ou en prise avec l’action, tant dans leur processus de réflexion que dans leur résultat final et servant véritablement à travailler sur ces expériences interculturelles ?	Les représentations graphiques et les images sont un moyen intéressant pour mettre en lumière les spécificités et contrastes culturels du management. Jusqu’ici, il n’avait cependant pas été question d’avoir recours au dessin émanant véritablement d’acteurs directement impliqués dans des situations interculturelles, rendant ainsi compte de leur expérience. Cet article illustre par des images représentant diverses scènes de coopérations franco-allemandes dessinées par des cadres dirigeants, comment ils perçoivent les situations de management d’une façon ludique et les incitent à la réflexion et au développement des compétences interculturelles.
« Quelque chose de l’inconscient »
Authors: Cupa Dominique 
Published: January 2017

En seconde topique, Freud attribue au moi une part inconsciente possédant une fonction de résistance aveugle liée au sentiment de culpabilité et au masochisme inconscients. Cette force négativante signe l’existence d’un troisième inconscient et la présence de la pulsion de mort dans le moi. Ce travail propose l’hypothèse d’associer à cette fonction, une fonction objectalisante signant la présence d’Éros. Elle génère un espace transitionnel interne de réflexivité accueillant et transformant les motions pulsionnelles du ça, permettant « la détachabilité », produisant la matrice du fantasme. Le récit du travail analytique avec un patient soutient cliniquement le propos.
Le travail onirique du moi inconscient ,
Authors: Van Lysebeth-Ledent Michèle 
Published: January 2017

Certains rêves de l’analysant mettent en évidence la nécessité de penser-rêver la situation émotionnelle liée à une défaillance de l’analyste. Ils témoignent souvent de l’existence d’un clivage entre un préconscient paralysé et un moi inconscient opérationnel, figurant le vécu. Le clivage souligne l’antagonisme de ces deux fonctionnements. L’auteure élargit la notion de moi inconscient et lui reconnaît une dimension élaboratrice analogue au « travail-alpha-du-rêve » de Bion. Le clivage préconscient/moi inconscient est la règle chez certains analysants comme l’illustre une vignette clinique.
Sur le chemin du maléfique... Le moi inconscient
Authors: Lecoq Arlette 
Published: January 2017

Le maléfique est pluriel et le moi inconscient polysémique. La figure du double de Dostoïevski, une réaction thérapeutique négative, une réflexion sur le négatif et l’inhumain font apparaître diverses facettes du moi inconscient mises au service du maléfique : surmoi, cli-vage, résistance, élaboration négative. Par ailleurs, certains artistes contribuent au travail de culture et à l’élargissement de la conscience de soi publique.
Prise en otage du moi inconscient dans le terrorisme religieux extrémiste
Authors: Hirsch Denis 
Published: January 2017

Cet article traite des mécanismes intrapsychiques et inter-psychiques qui aliènent le moi inconscient dans le phénomène du terrorisme radical religieux. S’y intriquent ¬psychologie individuelle et psychologie collective. Trois niveaux complémentaires d’aliénation et de « prise en otage » du moi inconscient sont repérés : régression au moi-idéal et identification adhésive à l’idole totalitaire ; identification mélancolique au père déchu et surmoi cruel déshumanisant ; communauté de déni des différences et de clivage entre mécréant et « sur-musulman ». Le terrorisme radical confirme l’hypothèse d’un masochisme désintriqué de mort.

Published: January 2017

AbstractMöbius syndrome is an extremely rare congenital disorder. We report a case of Möbius syndrome in a 2-year-old girl with bilateral convergent squint and left-sided facial weakness. The characteristic magnetic resonance imaging (MRI) findings of Möbius syndrome, which include absent bilateral abducens nerves and absent left facial nerve, were noted. In addition, there was absence of left anterior inferior cerebellar artery (AICA) and absence of bilateral facial colliculi. Clinical features, etiology, and imaging findings are discussed.
Black Feminist Reflections on Charles Mills's “Intersecting Contracts”
Authors: Gines Kathryn T. 
Published: January 2017

Abstract
This critical commentary is presented in two parts. The first section, “Intersecting Contracts: Conceptual Interventions and Aims,” provides an overview of Mills's analysis of the racia-sexual contract and the divergent positions of white men (full contractors and persons), white women (subcontractors with real, though inferior power), nonwhite men (subcontractors, though not on equal standing with white women because “race trumps gender”), and nonwhite women (nonpersons and noncontractors at the bottom of the structure and dominated by all three of the aforementioned groups). The second section, “Privilege and Patriarchy: Does ‘Race Generally Trump Gender’?,” shows how Mills offers an uneven representation of critiques presented by women of color theorists. For example, he focuses on the critiques of white women (and white feminism), emphasizing the asymmetry between white women and nonwhite men as well as the tensions between white women and nonwhite women. This article also problematizes Mills's claim that “race generally trumps gender” and argues for a more nuanced analysis of nonwhite men's participation in patriarchy and privilege.
The Pragmatics of Resistance: Framing Anti-Blackness and the Limits of Political Ontology
Authors: Kline David 
Published: January 2017

AbstractThis article argues that Frank B. Wilderson's political ontology can be read as both a critique and a radicalization of Giorgio Agamben's formal political-ontological framework constructed around the two extreme poles of sovereignty and bare life. Wilderson critiques and expands Agamben's framework by locating the zero point of political abjection not within bare life, which is still implicated within the ontological zone of Human being by way of an included exclusion, but within Black social death, which is cut off absolutely from Human being. While such a political ontological framework provides an extremely powerful optic for the absolute ontological abjection of Black existence in relation to all other racial positions in the modern West, its absolute prioritization limits the scope of an analysis of power relations that might offer an account of racial positioning that is both broader than and resistant to the political ontology of Western race relations. In conclusion, turning to Fred Moten's Black optimism and Deleuze's and Guattari's account of micropolitics and lines of flight, the article argues for a pragmatics of resistance that finds its practical condition of possibility within the micropolitical field of power relations that marks an excess to the anti-Black macropolitics of political ontology.
Disruptive Silences: The AME Church and Dominican-Haitian Relations
Authors: Davidson Christina Cecelia 
Published: January 2017

Abstract
Often recognized for its advocacy on behalf of African descendants, the African Methodist Episcopal (AME) Church has been silent on issues regarding anti-Haitian sentiment in the Dominican Republic. By tracing the historical connection between Black America and Haiti in the nineteenth century and recounting the twentieth-century history of the AME Church in the Dominican Republic, this article explains how an institution created in defense of racial equality could inadvertently facilitate its own silencing. Using archival research, ethnography, and interviews, this article critically analyzes narratives that distance Dominican African Methodists from African Americans and Haitians. It argues that such silences in the AME Church are the result of the church's social marginalization in the Dominican Republic, African American leaders' habitual neglect of the AME Church's Dominican branches, and the assimilation of Black Anglophone migrants into Dominican culture.

Strengthening alternative dispute resolution in consumer affairs by directive ADR and ODR regulation
In his column ‘Versterking alternatieve geschilbeslechting in consumentenzaken door richtlijn ADR en verordening ODR’ Koos Nijgh, head of the legal department of the ‘Stichting Geschillencommissies voor Consumentenzaken (SGC)’ gives an overview of how the SGC should anticipate the recent European legislative developments regarding ADR. After a brief summary on how the SGC functions, he analyses the European legislative demands and the policy the SGC has adopted. The author concludes that the impact of the new legislation is overseeable and that the SGC will do even better in the future.
The role of transdermal buprenorphine in the treatment of
chronic pain in elderly patients
Authors: Widenka Marek , Leppert Wojciech 
Published: January 2017

Buprenorphine is a synthetic opioid with partially agonist effects on μ (MOR) receptors and
slightly less internal activity compared to morphine. Buprenorphine binds with κ1 (KOR 1), κ2 (KOR 2), δ
(DOR) receptors and with ORL–1 (orphan–related ligand–1, NOR) receptors. The drug is absorbed after
transmucosal (approximately 30–50%) and transdermal (biological bioavailability equals approximately 50%)
route of administration due to significant lipophilicity. Buprenorphine concentration in plasma slowly increases
after transdermal patch application reaching minimal effective concentrations after approximately 12–24 h
and maximal concentrations of the drug in the serum after approximately 60–80 h. The drug is metabolized
in the liver, mainly through CYP3A4 to an active metabolite – norbuprenorphine. Both buprenorphine and
norbuprenorphine undergo subsequently glucuronidation through conjugates and in this forms are excreted with the bile. The majority of the drug is excreted with the stool in the form of unbound buprenorphine or
norbuprenorphine with 10–30% of the drug excreted with the urine. Buprenorphine metabolism causes
that the risk of pharmacokinetic drug interactions is low. Moreover, buprenorphine is safe drug in patients
with renal impairment. Mild and moderate hepatic impairment do not significantly influence buprenorphine
pharmacokinetics. In this paper a review of buprenorphine clinical studies (with randomization and nonrandomized)
conducted in elderly patients was undertaken. Buprenorphine administered in patches by the
transdermal is frequently used in the treatment of chronic pain in cancer patients and in the course of other
diseases. Buprenorphine may be used successfully in the treatment of neuropathic pain. Buprenorphine
administered by transdermal route is preferred opioid analgesic in elderly patients with moderate to severe
chronic pain due to beneficial pharmacodynamics and pharmacokinetics
