Published: March 2017

This article introduces the German National Study on Early Childhood Education and Care (NUBBEK). NUBBEK offers an empirical basis for the study of care and education within and outside of the family for two- (n = 1242) and four-year old children (n = 714). Data were collected in 2010 and 2011; 27% of all children grew up in either Turkish or Russian immigrant families. NUBBEK adopted a socio-ecological perspective on education and care. Data on orientation, structure, and processes were gathered in a parallel fashion in both home environment and 567 external day care settings. The article provides information on the design of NUBBEK, the sample, the instruments (interviews, questionnaires, observations, tests), as well as on selected intra-class-coefficients (ICC) for potential multilevel-analyses. In fall 2014, the data will be available for the scientific community at the GESIS data archive.
Zusammenfassung
Dieser Beitrag stellt die Nationale Untersuchung zur Bildung, Betreuung und Erziehung in der frühen Kindheit (NUBBEK) vor. NUBBEK bietet eine empirische Basis zur Erforschung der familiären und außerfamiliären Betreuung von zweijährigen (n = 1242) und vierjährigen (n = 714) Kindern. Die Daten stammen aus den Jahren 2010 bis 2011; 27% der Kinder hatten einen türkischen oder einen russischen Migrationshintergrund. Die NUBBEK-Studie orientierte sich an einer sozialökologischen Konzeption von Bildung und Entwicklung. Orientierungsqualität, Strukturqualität sowie Prozessqualität wurden weitgehend parallel sowohl für das Betreuungssetting Familie erhoben als auch für 567 Krippen-, Kindergarten- und Tagespflegegruppen. Das Design der Studie, die Stichprobe, die eingesetzten Verfahren (Beobachtungen, Interviews, Fragebögen, Testungen der Kinder) sowie ausgewählte Intraklassen-Korrelationskoeffizienten (ICC) für potenzielle Mehrebenanalysen werden vorgestellt. Die Daten sind ab Herbst 2014 im Datenarchiv von GESIS für Forschungseinrichtungen zugänglich.

Published: March 2017

Background: Differentiating Parkinson’s disease and atypical parkinsonism on clinical parameters is challenging, especially in early disease courses. This is due to large overlap in symptoms and because the so called red flags, i.e. symptoms indicating atypical parkinsonism, have not (fully) developed. Brain MRI can aid to improve the accuracy and confidence about the diagnosis. Objective and Methods: In the current paper, we discuss when brain MRI should be performed in the diagnostic work-up of parkinsonism, our preferred brain MRI scanning protocol, and the diagnostic value of specific abnormalities. Results and Conclusions: The main purpose of brain MRI is to assess cerebrovascular damage, and to exclude other possible – and sometimes treatable – causes of parkinsonism, such as normal pressure hydrocephalus. Furthermore, brain MRI can support the possible or probable diagnosis of a specific form of atypical parkinsonism.
A Deep Chart (the Aqua-Face of Deep Mapping)
Authors: Hayman Eleanor , Wedge Mark , James Colleen 
Published: March 2017

This paper showcases a counter-mapping project with the Tlingit and Tagish peoples of the circumpolar north. Engaging critically with the evolving theory and practice of deep mapping we reveal how collaborative water research designed to provide a framework for indigenous water legislation is expressed visually on a Google Earth platform. This aquatic counter-map, or as we call it, a deep chart, not only empowers the Tlingit and Tagish, but reclaims and revitalises critical cultural values, whilst simultaneously preserving linguistic and cultural memory in a digital form. More broadly, the deep chart is currently being brought into global water ethic debates as a visual ethno-cartographic example of an alternative relationship humans might have with water, paving the way for a new water consciousness. This is in direct contrast to current, dominant and sometimes destructive global water governance and water management models and practices. We showcase a participatory and aqua-centric deep charting paradigm that is evolving through Geographics Information Science (GIS) platforms in collaboration with the CTFN (Tlingit and Tagish) community and government. This research challenges the contemporary cartography of the dominant Anglo-American valuing of water. It also presents an alternative water vision that we argue can shift ‘terra-centric’ thinking towards ‘aqua-centric’ thinking. It further provides a blueprint for informing global water ethics debates.

The malacological activity at the Société linnéenne de Lyon between 1822 and 1960
Some famous personalities were able to share their passion of molluscs to other Linneans and thus allowed to develop a certain malacologie activity within the Society. This malacologie activity is approached in a diachronic way following, in the Lyon context, the succession of the various schools which marked out the history of French malacology.

Abstract
We report the discovery of a high mass ratio planet, q = 0.012, i.e., 13 times higher than the Jupiter/Sun ratio. The host mass has not yet been measured but can be determined or strongly constrained from adaptive optics imaging. The planet was discovered in a small archival study of high-magnification events in pure-survey microlensing data, which was unbiased by the presence of anomalies. The fact that it was previously unnoticed may indicate that more such planets lie in archival data and could be discovered by a similar systematic study. In order to understand the transition from predominantly survey+followup to predominately survey-only planet detections, we conduct the first analysis of these detections in the observational (s, q) plane. Here s is the projected separation in units of the Einstein radius. We find some evidence that survey+followup is relatively more sensitive to planets near the Einstein ring, but that there is no statistical difference in sensitivity by mass ratio.
The Limited Impact of Outflows: Integral-field Spectroscopy of 20 Local AGNs

Published: March 2017

Abstract
To investigate active galactic nucleus (AGN) outflows as a tracer of AGN feedback on star formation, we perform integral-field spectroscopy of 20 type 2 AGNs at z < 0.1, which are luminous AGNs with [O iii] luminosity > 10

erg s−1 that exhibit strong outflow signatures in the [O iii] kinematics. By decomposing the emission-line profile, we obtain the maps of the narrow and broad components of the [O iii] and Hα lines, respectively. The broad components in both [O iii] and Hα represent the nongravitational kinematics, that is, gas outflows, while the narrow components, especially in Hα, represent the gravitational kinematics, that is, the rotational disk. By using the integrated spectra within the flux-weighted size of the narrow-line region, we estimate the energetics of the gas outflows. The ionized gas mass is 1.0–38.5

, and the mean mass outflow rate is 4.6 ± 4.3 M
⊙ yr−1, which is a factor of ∼260 higher than the mean mass accretion rate of 0.02 ± 0.01

yr−1. The mean energy injection rate of the sample is 0.8% ± 0.6% of the AGN bolometric luminosity

, while the momentum flux is (5.4 ± 3.6) ×

on average, except for the two most kinematically energetic AGNs with low

, which are possibly due to the dynamical timescale of the outflows. The estimated outflow energetics are consistent with the theoretical expectations for energy-conserving outflows from AGNs, yet we find no supporting evidence of instantaneous quenching of star formation due to the outflows.

Abstract
We combine deep Hubble Space Telescope grism spectroscopy with a new Bayesian method to derive maps of gas-phase metallicity for 10 star-forming galaxies at high redshift (

). Exploiting lensing magnification by the foreground cluster MACS1149.6+2223, we reach sub-kiloparsec spatial resolution and push the limit of stellar mass associated with such high-z spatially resolved measurements below

for the first time. Our maps exhibit diverse morphologies, indicative of various effects such as efficient radial mixing from tidal torques, rapid accretion of low-metallicity gas, and other physical processes that can affect the gas and metallicity distributions in individual galaxies. Based upon an exhaustive sample of all existing sub-kiloparesec resolution metallicity gradient measurements at high z, we find that predictions given by analytical chemical evolution models assuming a relatively extended star-formation profile in the early disk-formation phase can explain the majority of observed metallicity gradients, without involving galactic feedback or radial outflows. We observe a tentative correlation between stellar mass and metallicity gradients, consistent with the “downsizing” galaxy formation picture that more massive galaxies are more evolved into a later phase of disk growth, where they experience more coherent mass assembly at all radii and thus show shallower metallicity gradients. In addition to the spatially resolved analysis, we compile a sample of homogeneously cross-calibrated integrated metallicity measurements spanning three orders of magnitude in stellar mass at z ∼ 1.8. We use this sample to study the mass–metallicity relation (MZR) and find that the slope of the observed MZR can rule out the momentum-driven wind model at a 3σ confidence level.

Abstract
We report the ALMA Cycle 2 observations of the Class I binary protostellar system L1551 NE in the 0.9 mm continuum, C18O (3–2), 13CO (3–2), SO (78–67), and CS (7–6) emission. At 0.″18 (=25 au) resolution, ∼4 times higher than that of our Cycle 0 observations, the circumbinary disk (CBD) as seen in the 0.9 mm emission is shown to be composed of a northern and a southern spiral arm, with the southern arm connecting to the circumstellar disk (CSD) around Source B. The western parts of the spiral arms are brighter than the eastern parts, suggesting the presence of an m = 1 spiral mode. In the C18O emission, the infall gas motions in the interarm regions and the outward gas motions in the arms are identified. These observed features are well reproduced with our numerical simulations, where gravitational torques from the binary system impart angular momenta to the spiral-arm regions and extract angular momenta from the interarm regions. Chemical differentiation of the CBD is seen in the four molecular species. Our Cycle 2 observations have also resolved the CSDs around the individual protostars, and the beam-deconvolved sizes are 0.″29 × 0.″19 (=40 × 26 au) (P.A. = 144°) and 0.″26 × 0.″20 (=36 × 27 au) (P.A. = 147°) for Sources A and B, respectively. The position and inclination angles of these CSDs are misaligned with those of the CBD. The C18O emission traces the Keplerian rotation of the misaligned disk around Source A.
Neutron Star Kicks by the Gravitational Tug-boat Mechanism in Asymmetric Supernova Explosions: Progenitor and Explosion Dependence
Authors: Janka Hans-Thomas 
Published: March 2017

Abstract
Asymmetric mass ejection in the early phase of supernova (SN) explosions can impart a kick velocity to the new-born neutron star (NS). For neutrino-driven explosions the NS acceleration has been shown to be mainly caused by the gravitational attraction of the anisotropically expelled inner ejecta, while hydrodynamic forces contribute on a subdominant level, and asymmetric neutrino emission plays only a secondary role. Two- and three-dimensional hydrodynamic simulations have demonstrated that this gravitational tug-boat mechanism can explain the observed space velocities of young NSs up to more than 1000 km s−1. Here, we discuss how the NS kick depends on the energy, ejecta mass, and asymmetry of the SN explosion, and what role the compactness of the pre-collapse stellar core plays for the momentum transfer to the NS. We also provide simple analytic expressions for the NS velocity in terms of these quantities. Referring to results of hydrodynamic simulations in the literature, we argue why, within the discussed scenario of NS acceleration, electron-capture SNe, low-mass Fe-core SNe, and ultra-stripped SNe can be expected to have considerably lower intrinsic NS kicks than core-collapse SNe of massive stellar cores. Our basic arguments also remain valid if progenitor stars possess large-scale asymmetries in their convective silicon and oxygen burning layers. Possible scenarios for spin-kick alignment are sketched. Much of our discussion stays on a conceptual and qualitative level, and more work is necessary on the numerical modeling side to determine the dependences of involved parameters, whose prescriptions will be needed for recipes that can be used to better describe NS kicks in binary evolution and population synthesis studies.
Sheath-accumulating Propagation of Interplanetary Coronal Mass Ejection
Authors: Takahashi Takuya , Shibata Kazunari 
Published: March 2017

Abstract
Fast interplanetary coronal mass ejections (ICMEs) are the drivers of strong space weather storms such as solar energetic particle events and geomagnetic storms. The connection between the space-weather-impacting solar wind disturbances associated with fast ICMEs at Earth and the characteristics of causative energetic CMEs observed near the Sun is a key question in the study of space weather storms, as well as in the development of practical space weather prediction. Such shock-driving fast ICMEs usually expand at supersonic speeds during the propagation, resulting in the continuous accumulation of shocked sheath plasma ahead. In this paper, we propose a “sheath-accumulating propagation” (SAP) model that describes the coevolution of the interplanetary sheath and decelerating ICME ejecta by taking into account the process of upstream solar wind plasma accumulation within the sheath region. Based on the SAP model, we discuss (1) ICME deceleration characteristics; (2) the fundamental condition for fast ICMEs at Earth; (3) the thickness of interplanetary sheaths; (4) arrival time prediction; and (5) the super-intense geomagnetic storms associated with huge solar flares. We quantitatively show that not only the speed but also the mass of the CME are crucial for discussing the above five points. The similarities and differences between the SAP model, the drag-based model, and the“snow-plow” model proposed by Tappin are also discussed.

Entre cigale et fourmi : regards sur la politique économique de la gauche au Brésil
Authors: Gaudillière Jean-Paul , Jami Irène 
Published: March 2017

Au milieu des années 2000, l’Amérique latine pouvait apparaître comme le laboratoire d’une gauche qui – de l’Équateur au Brésil, en passant par la Bolivie – s’engageait dans un processus original d’exercice du pouvoir, se revendiquant à la fois de la lutte contre la pauvreté, de la mobilisation de l’État en faveur de nouvelles formes de croissance économique, voire de l’empowerment des populations indigènes. Mouvements s’en était fait l’écho. Dix ans plus tard, la scène a radicalement changé. Tous les gouvernements de gauche sont en situation d’échec. Pierre Salama, spécialiste des questions de développement et fin connaisseur des économies latino-américaines, revient ici sur les choix qui – de la priorité à l’exploitation des matières premières à l’accommodement avec la montée des inégalités, sans parler de l’instrumentalisation de la corruption – sont, au-delà des effets de la crise financière surgie en 2008, à l’arrière-plan de ce retournement.
Face à Trump, quel avenir pour la gauche aux États-Unis ?
Authors: Cohen Jim , Talpin Julien 
Published: March 2017

La gauche américaine a connu un moment historique de visibilité en 2016 grâce à la campagne de Bernie Sanders dans les élections primaires. Suite à l’élection de Donald Trump elle oscille aujourd’hui entre découragement et mobilisation. Comment résister à la vague réactionnaire, inverser la droitisation du pays et constituer des majorités politiques vectrices de justice sociale ? Ces questions stratégiques auxquelles est désormais confrontée la gauche américaine ne sont pas sans rapport avec celles qui sont posées aux gauches européennes.
Jeremy Corbyn et le Parti travailliste : une drôle de paix
Authors: Walthéry Pierre 
Published: March 2017

La nette réélection de Jeremy Corbyn à la tête du Parti travailliste a calmé les tensions internes entre la direction et le groupe parlementaire qui lui est majoritairement hostile. Une « drôle de paix » s’est instaurée entre les deux camps. Mais il est peu probable que ce soit là la fin des hostilités. Corbyn peine à imposer son leadership et sa politique à l’ensemble de son parti en dépit d’un large soutien militant. Il doit subir l’opposition totale de la « droite blairiste » qui pense qu’il est illégitime à ce poste, ainsi que d’une majorité hétéroclite qui doute de sa capacité à rassembler le parti et à le mener à la victoire. Ce face-à-face handicape pour le moment le travail d’opposition au gouvernement conservateur qui mène une politique d’austérité radicale et s’apprête à faire sortir le Royaume-Uni de l’Union européenne.

Abstract
In chronic diseases, such as HIV infection, plasmacytoid dendritic cells (pDCs) are rendered dysfunctional, as measured by their decreased capacity to produce IFN-α. In this study, we identified elevated levels of T cell Ig and mucin-domain containing molecule-3 (Tim-3)–expressing pDCs in the blood of HIV-infected donors. The frequency of Tim-3–expressing pDCs correlated inversely with CD4 T cell counts and positively with HIV viral loads. A lower frequency of pDCs expressing Tim-3 produced IFN-α or TNF-α in response to the TLR7 agonists imiquimod and Sendai virus and to the TLR9 agonist CpG. Thus, Tim-3 may serve as a biomarker of pDC dysfunction in HIV infection. The source and function of Tim-3 was investigated on enriched pDC populations from donors not infected with HIV. Tim-3 induction was achieved in response to viral and artificial stimuli, as well as exogenous IFN-α, and was PI3K dependent. Potent pDC-activating stimuli, such as CpG, imiquimod, and Sendai virus, induced the most Tim-3 expression and subsequent dysfunction. Small interfering RNA knockdown of Tim-3 increased IFN-α secretion in response to activation. Intracellular Tim-3, as measured by confocal microscopy, was dispersed throughout the cytoplasm prior to activation. Postactivation, Tim-3 accumulated at the plasma membrane and associated with disrupted TLR9 at the submembrane. Tim-3–expressing pDCs had reduced IRF7 levels. Furthermore, intracellular Tim-3 colocalized with p85 and IRF7 within LAMP1+ lysosomes, suggestive of a role in degradation. We conclude that Tim-3 is a biomarker of dysfunctional pDCs and may negatively regulate IFN-α, possibly through interference with TLR signaling and recruitment of IRF7 and p85 into lysosomes, enhancing their degradation.

Abstract
The immune and reproductive functions of human NK cells are regulated by interactions of the C1 and C2 epitopes of HLA-C with C1-specific and C2-specific lineage III killer cell Ig-like receptors (KIR). This rapidly evolving and diverse system of ligands and receptors is restricted to humans and great apes. In this context, the orangutan has particular relevance because it represents an evolutionary intermediate, one having the C1 epitope and corresponding KIR but lacking the C2 epitope. Through a combination of direct sequencing, KIR genotyping, and data mining from the Great Ape Genome Project, we characterized the KIR alleles and haplotypes for panels of 10 Bornean orangutans and 19 Sumatran orangutans. The orangutan KIR haplotypes have between 5 and 10 KIR genes. The seven orangutan lineage III KIR genes all locate to the centromeric region of the KIR locus, whereas their human counterparts also populate the telomeric region. One lineage III KIR gene is Bornean specific, one is Sumatran specific, and five are shared. Of 12 KIR gene–content haplotypes, 5 are Bornean specific, 5 are Sumatran specific, and 2 are shared. The haplotypes have different combinations of genes encoding activating and inhibitory C1 receptors that can be of higher or lower affinity. All haplotypes encode an inhibitory C1 receptor, but only some haplotypes encode an activating C1 receptor. Of 130 KIR alleles, 55 are Bornean specific, 65 are Sumatran specific, and 10 are shared.
