Authors: Colpas Fredy , Tarón Arnulfo , Fong Waldyr
Published: May 2017

Algunos residuos agrícolas pueden ser útiles para producir materiales adsorbentes como son los de carbones activados. Tal es el caso del Zuro de maíz, el cual fue utilizado como material de partida en esta investigación, Para la preparación de carbón activado, inicialmente el zuro libre de granos de maíz es carbonizado a temperatura de 400 °C, posteriormente los carbonizados fueron activados químicamente con ácido ortofosfórico, los carbones activados obtenidos fueron modificados con ácido nítrico y peróxido de hidrógeno, previo calentamiento a 600°C para observar su desarrollo textural. Los sólidos fueron caracterizados a través de un análisis, para la determinación del área superficial se realizaron isotermas de adsorción mediante el método BET, utilizando equipo Micromeritics Gemini 2375. La activación con ácido ortofosfórico aumentó el contenido de carbono y disminuyó el contenido de oxígeno. El área de microporos se incrementó por el tratamiento con HNO3 y H 2O2 desde 278,3 m2 g-1 hasta 401,7m2 g-1 y 446,4 m2g-1 respectivamente y la mayor parte del área total desarrollada correspondió a microporos. El pH generado por los carbones fue aproximadamente 3, el cual se determinó en soluciones acuosas luego de lavado con agua destilada; así mismo, estos materiales mostraron valores en los grupos COOH hasta 2,12 meq g-1.

Metabolismo urbano: herramienta para la sustentabilidad de las ciudades
Authors: Díaz Álvarez Cristian Julián
Published: May 2017

La dinámica poblacional y formas de vida urbana de las medianas y grandes ciudades de Latinoamérica están determinando operaciones críticas que frenan el crecimiento económico, socavan el desarrollo, deterioran el ambiente, afectan la salud de sus residentes y reducen la oferta de bienes y servicios ambientales de los ecosistemas de soporte. Son escenarios de presión con los que se corre el riesgo de exceder los límites permisibles de su homeostasis y adaptabilidad; y por consiguiente, de exacerbar su vulnerabilidad en momentos en que la variabilidad y el cambio climático disminuyen las probabilidades de supervivencia de los sistemas humanos. Por tal motivo, y en aras de coadyuvar con la sustentabilidad y competitividad de la ciudad, el estudio del Metabolismo Urbano se constituye en un esfuerzo técnico, político y económico que facilita el entendimiento de sus redes de abastecimiento de materiales y energía, que busca la eficiencia y eficacia de sus procesos de transformación, así como la minimización del daño ambiental de sus desechos, permitiendo a los gestores de política anticiparse a eventos no deseados con base en las señales del presente.
Urban Challenges in India and the Mission for a Sustainable Habitat
Authors: Ghosh Ruchira , Kansal Arun
Published: May 2017

This paper presents urbanization challenges in India and initiatives taken to address them. Urbanization in India is characterized by skewed urban growth between cities by large population influx creating distinct variation in core and periphery of cities in terms of urban form and services. Key challenges include growth of slums, inadequate management of solid waste, decrease in per capita water availability and unreliable water quality, inadequate sewage coverage and deteriorating ambient air. Although, these issues are not new or specific for India, what is new are the drivers and pressures behind these problems. The paper illustrates the challenges of Indian urbanization in the light of resource inefficiency, resistance to adopt upcoming technologies that do not have direct financial benefits, weak enforcement of laws, and inadequacy in regulatory framework. It also presents instances of active participation of non–formal and formal sectors in addressing sustainability challenges. There is also a recognition of the fact that city governments are faced with multiple sustainability agendas of climate adaptation. This presents a decisional challenge for planners and city administrations. Benefits incidental to a particular policy goal can help drive the implementation of the policy and sustain it in the long term, but only when the inherent risk trade–offs, if present, can be managed.
Extraños desechables: raza e inmigración en la era de la globalización
Authors: Oboler Suzanne
Published: May 2017

Resumen | Este trabajo procura analizar la crisis general de la noción de comunidad mediante la exploración de las maneras en que la inmigración y la integración de los inmigrantes en esta era globalizada están estimulando una forma particularmente virulenta de racismo, con raíces en la xenofobia, que está sirviendo para redefinir los mismos términos de pertenencia nacional y su expresión política en la ciudadanía.Con enfoque particular sobre personas de ascendencia mexicana en los Estados Unidos, propongo que, en el ambiente político y económico vigente, el racismo y la xenofobia contra los inmigrantes, exacerbados por el énfasis sobre seguridad de la dinámica política, aseguran que —independientemente del estatus oficial de ciudadano— los latinos y de manera particular los mexicano-americanos se están transformando en “ciudadanos desechables”.Más aun —una vez redefinidos como “mexicanos”, sin importar su país de origen o momento de llegada— los latinos están siendo relegados a la condición de “extraños desechables” en los Estados Unidos.

 

Disposable Strangers: Race and Migration in the Era of Globalization

Abstract | This paper seeks to address the general crisis in the notion of community by exploring the ways that immigration and immigrant integration in the global era are stoking a particularly virulent form of racism, rooted in a xenophobia that is instrumental to redefining the very terms of national belonging and its political expression in citizenship.Focusing on the experience of people of Mexican descent in the United States I argue that, in the prevailing political and economic climate, racism and xenophobia against immigrants, exacerbated by the security focus of political dynamics, ensures that, regardless of official citizenship status, Latinos, and particularly Mexican Americans, are becoming “disposable citizens.” Moreover, now recast as “Mexicans”, Latinos, regardless of their national origin or time of arrival, are being relegated to the status of “disposable strangers” in the United States.

De la evolución al valor de uso, ida y vuelta: exploraciones en la domesticación y diversificación de plantas
Authors: Jardón Barbolla Lev
Published: May 2017

Resumen | La diversidad de las plantas domesticadas ha sido de interés para la biología desde el programa darwiniano de investigación. Reconociendo a esa diversidad como un producto de la historia, cabría preguntarse si ésta es un producto estático, ya dado, o antes bien es la manifestación de un conjunto de procesos activos. Entonces se requiere una aproximación dialéctica al estudio de la diversidad agro-biológica. Esto permite revisitar una serie de problemas teóricos, incluyendo el de la conceptualización del conjunto de interacciones que permiten que esa diversidad haya sido creada, pero también mantenida a pesar de perturbaciones por otros elementos del sistema. Y también lleva a entender la diversidad en plantas domesticadas desde dos planos entrelazados: 1) el de las consecuencias genéticas del proceso de domesticación y 2) el del espacio social en el que ocurre un tipo de selección artificial capaz de generar una diversidad de valores de uso. Así, es posible construir una hipótesis de trabajo interdisciplinario: que la diversidad en plantas domesticadas no es solamente el resultado de intentar incrementar la magnitud escalar de las cosechas, sino un resultado coevolutivo en el que la producción de diferentes valores de uso, parte de la formación de la diversidad cultural, ha sido clave. Mesoamérica es un espacio idóneo para contrastar esta hipótesis.
Decrecimiento, post-desarrollo y transiciones: una conversación preliminar
Authors: Escobar Arturo
Published: May 2017

Resumen | Este trabajo procura iniciar un diálogo entre los marcos de referencia del decrecimiento y el post-desarrollo, colocándolos dentro del campo más amplio de los discursos sobre las transiciones ecológica y de civilización, y procurando tender puentes entre propuestas emergentes del Norte y aquellas generadas en el Sur global. Sostenemos que este diálogo no sólo puede ser mutuamente enriquecedor para ambos movimientos, sino también esencial para una efectiva política de transformación. La primera parte de este trabajo presenta un panorama breve de los discursos de transición, particularmente en el Norte. La segunda parte discute de manera sucinta las principales tendencias en el post-desarrollo en América Latina, incluyendo el Buen Vivir, los derechos de la naturaleza, la crisis de la civilización, y el concepto de “alternativas al desarrollo”. Con estos elementos en la mano, la tercera parte intenta un diálogo preliminar entre el decrecimiento y el post-desarrollo; identifica puntos de convergencia y tensión, y termina bosquejando algunas áreas de investigación que podrían ser de particular interés para los estudiosos del decrecimiento.
Interseccionalidad, un “concepto viajero”: orígenes, desarrollo e implementación en la Unión Europea
Authors: La Barbera MariaCaterina
Published: May 2017

Resumen | La interseccionalidad constituye una de las mayores contribuciones conceptuales del feminismo en los últimos veinticinco años. La luz que arroja en el estudio de los complejos mecanismos de discriminación ha permitido identificar la diversidad de las interacciones generadas por la subordinación de muy diferente tipo: por razones de género, orientación sexual, etnia, religión, origen nacional, (dis)capacidad, nivel socioeconómico y otras. En este trabajo intento bosquejar el desarrollo de este concepto, desde sus primeros tiempos en los estudios jurídicos hasta su expansión desigual y asimétrica en las ciencias sociales y en las diferentes áreas geográficas. Dicha heterogeneidad obstaculiza, en algunas regiones, el empleo de esta herramienta conceptual en la práctica, y subraya la necesidad de indagar en las diferencias y matices —que suelen originarse en las interacciones con culturas, prácticas e instituciones existentes— con el objeto de mejorar los niveles de praxis y estrategias locales.
Testing objectification theory with Chinese undergraduate women and men
Authors: Zheng Yong , Sun Qingqing
Published: May 2017

We tested the applicability of objectification theory to the prediction of disordered eating and depressed mood among Chinese undergraduate students. Participants (N = 430) completed measures of body surveillance, body shame, appearance anxiety, level of internal awareness, flow,
disordered eating, and depressed mood. Results of structural equation modeling revealed the model of objectification theory provided a poor fit to the data for both genders, but 2 exploratory models with good fit were generated after subsequent modification to the model. For women, body shame
and appearance anxiety mediated the relationships among body surveillance, disordered eating, and depressed mood. Furthermore, body surveillance indirectly influenced women's level of internal awareness and flow via body shame and appearance anxiety, which led to disordered eating and depressed
mood. This pattern of relationships was similar for men, except for flow, which was not related to the outcome variables. We concluded that objectification theory is applicable to women and men in China.
Aggression differences among nonoffender, onset-offender, and recidivist migrant youth in China

Published: May 2017

We examined aggression differences among nonoffender, onset-offender, and recidivist migrant youth in China using explicit and implicit measures. From 2011 to 2015, data were collected via face-to-face surveys and the Implicit Association Test (IAT). Male migrant youth (N = 227;
106 nonoffenders, 78 onset-offenders, and 43 recidivists) completed the Chinese version of the Buss and Perry Aggression Questionnaire, and 125 male migrant youth (68 nonoffenders, 31 onset-offenders, and 26 recidivists) performed two IATs assessing implicit attitudes and implicit self-concepts
about aggression. The results showed that the IAT was reliable in an Asian context with offenders, and that the onset-offenders demonstrated greater aggression compared with those in the recidivist and nonoffender groups. Our findings suggest that onset-offenders may have more accurate self-awareness
than do recidivists and incarceration may influence attitudes toward aggression in a positive way. Such knowledge is important for interventions that target juvenile delinquency.
Organizational citizenship pressure, compulsory citizenship behavior, and work–family conflict
Authors: Liu Yinbin , Zhao Hongdan , Sheard Geoff
Published: May 2017

We sought to explore the mediating effect of compulsory citizenship behavior in the relationship between organizational citizenship pressure and work–family conflict, and the moderating role of job autonomy in influencing the mediation. Through a 3-wave web-based survey of 312
employees in China, we found that organizational citizenship pressure was positively related to compulsory citizenship behavior, the positive impact of citizenship pressure on work–family conflict was mediated by compulsory citizenship behavior, and job autonomy mitigated the above mediation
effect. Our findings provide insight into the mechanisms that underpin the effect of organizational citizenship pressure on work–family conflict.
Effect of workplace environment cleanliness on judgment of counterproductive work behavior
Authors: Huangfu Gang , Lv Feng , Sheng Cheng , Shi Xiaochen
Published: May 2017

We examined the association between workplace environment cleanliness and employees' judgment of counterproductive work behavior (CWB). We recruited 59 participants who were employees of a large company in China, and assigned 28 to a clean workroom and 31 to a dirty workroom. We measured
their judgment of whether or not behavior was acceptable, using the Counterproductive Work Behavior Checklist. Results showed that participants working in a clean environment tended to regard CWB as less acceptable than did those in a dirty environment, that is, a cleaner environment led to
harsher judgment. Results suggested that there is a metaphorical association between environmental cleanliness and moral judgment. Theoretical and practical implications are discussed.

Densities and viscosities for binary mixtures of n-heptane with alcohols at different temperatures
Authors: Budeanu Maria , Dumitrescu Vasile
Published: May 2017

Densities (?) and viscosities (?) of the binary systems n-heptane with alcohols (ethanol, propan-1-ol and propan-2-ol) were measured at temperatures between 288.15 and 308.15 K and at atmospheric pressure, over the whole composition range. The excess values of molar volume (VE) and viscosity (?E) were calculated from experimental measurements. The excess functions of the binary systems were fitted to Redlich?Kister Equation. Comparison between experimental excess molar volume and the one calculated from Flory and Prigogine?Flory?Patterson theories, has also been done. The viscosity results were fitted to the equations of Grunberg?Nissan, Heric?Brewer, Jouyban?Acree and McAllister. Also, the activation energies of viscous flow have been obtained and their variations with compositions have been discussed.

Investigation of optical sensor approaches for real-time monitoring during fibre laser welding
Authors: De Bono Paola , Allen Chris , D'Angelo Giuseppe , Cisi Alessandro
Published: May 2017

Laser beam welding can be a high productivity joining process, offering significant benefits over conventional welding methods. However, the need for real-time monitoring of laser welding processes is important to provide information on the possible presence of imperfections formed during welding and guarantee quality assurance in production. Laser process monitoring methods are based on the recording of physical phenomena occurring during the laser-material interaction. This paper has investigated an established optical-based monitoring method, using photodiodes responsive to either visible or near-infrared emissions, to correlate the photodiode signals with different types of weld features, imperfections and/or process anomalies. These have included occurrence of internal porosity, changes in penetration depth and beam to joint alignment, deliberate changes in laser power and intentionally poor joint preparation, cleanliness or fit-up. Also, a new type of commercially available process monitoring approach was investigated, based on laser interferometry, to measure keyhole depth. The results of both approaches have confirmed which types of weld features, imperfections and/or process anomalies are most sensitive to these monitoring techniques, with potential to then implement these findings in to a future multisensor solution for real-time process control.

Authors: Madroñal M. , Galeano B.J. , Escobar N.J.
Published: May 2017

Nowadays, hospital physical asset management is gaining importance due to the size of its buildings, social relevance, operational and maintenance costs. The purpose of this document is to identify the Key Performance Indicators (KPIs) and categorize them into specific aspects of measurement of infrastructure performance. The lack of an adequate classification of performance indicators prevents the widespread use of performance measures for Facility Management (FM) in the health sector.This article shows a brief review of the state of art of FM KPIs based on a bibliographic search, taking into account international authors and reviewing their approaches and categorizations. The authors of this paper present a summary of the categorization and approach of hospital infrastructure management based on the documents examined, which may offer a more practical use for FM professionals in the healthcare sector. Facility Managers have to tackle too much data, which hinders to carry out a deeper analysis of the key performance indicators in future researches, attempting to generate indicators that match with the organization objectives and that lead to a more intelligent and efficient health infrastructure management.

OBJECTIVE To evaluate agreement among diplomates of the American College of Veterinary Anesthesia and Analgesia for scores determined by use of a simple descriptive scale (SDS) or a composite grading scale (CGS) for quality of recovery of horses from anesthesia and to investigate use of 3-axis accelerometry (3AA) for objective evaluation of recovery.

ANIMALS 12 healthy adult horses.

PROCEDURES Horses were fitted with a 3AA device and then were anesthetized. Eight diplomates evaluated recovery by use of an SDS, and 7 other diplomates evaluated recovery by use of a CGS. Agreement was tested with κ and AC1 statistics for the SDS and an ANOVA for the CGS. A library of mathematical models was used to map 3AA data against CGS scores.

RESULTS Agreement among diplomates using the SDS was slight (κ = 0.19; AC1 = 0.22). The CGS scores differed significantly among diplomates. Best fit of 3AA data against CGS scores yielded the following equation: RS = 9.998 × SG0.633 × ∑UG0.174, where RS is a horse's recovery score determined with 3AA, SG is acceleration of the successful attempt to stand, and ∑UG is the sum of accelerations of unsuccessful attempts to stand.

CONCLUSIONS AND CLINICAL RELEVANCE Subjective scoring of recovery of horses from anesthesia resulted in poor agreement among diplomates. Subjective scoring may lead to differences in conclusions about recovery quality; thus, there is a need for an objective scoring method. The 3AA system removed subjective bias in evaluations of recovery of horses and warrants further study.
Registration of ‘Renovation’ White Clover

Published: May 2017

‘Renovation’ (Reg. No. CV‐9, PI 680615), is a large‐leaved, synthetic intermediate type white clover (Trifolium repens f. hollandicum Erith ex Jav. & Soo) cultivar derived after hybridizing (i.e., population crosses) random, individual plants from a naturalized ecotype population from Oklahoma with those from the ‘Regal’, ‘Patriot’, ‘Tillman’, and ‘SRVR’ cultivars. Renovation was jointly developed, tested, and released in 2016 under the experimental designation NFWC04‐49 by the Samuel Roberts Noble Foundation, Ardmore, OK, and the University of Georgia Research Foundation, Athens, GA. ‘Durana’, an intermediate type white clover cultivar, and Patriot, a ladino × intermediate population hybrid, demonstrated that persistent cultivars are possible based on intermediate germplasm. Renovation was found to be an intermediate type based on seedhead number comparable to Durana but higher than Regal (ladino type). Renovation's leaf size is larger than Durana and equal to Patriot; its plant height and stolon characteristics are intermediate between Regal and Durana and more like Patriot. Renovation demonstrated animal performance and pasture growth rate much better than nitrogen‐fertilized controls when overseeded into deteriorating tall fescue pastures in replicated paddocks grazed by beef steers. Renovation is licensed for commercial production and sales to Smith Seed Services, Halsey, OR.
Genome‐Wide Analysis of Tar Spot Complex Resistance in Maize Using Genotyping‐by‐Sequencing SNPs and Whole‐Genome Prediction

Published: May 2017

Tar spot complex (TSC) is one of the most destructive foliar diseases of maize (Zea mays L.) in tropical and subtropical areas of Central and South America, causing significant grain yield losses when weather conditions are conducive. To dissect the genetic architecture of TSC resistance in maize, association mapping, in conjunction with linkage mapping, was conducted on an association‐mapping panel and three biparental doubled‐haploid (DH) populations using genotyping‐by‐sequencing (GBS) single‐nucleotide polymorphisms (SNPs). Association mapping revealed four quantitative trait loci (QTL) on chromosome 2, 3, 7, and 8. All the QTL, except for the one on chromosome 3, were further validated by linkage mapping in different genetic backgrounds. Additional QTL were identified by linkage mapping alone. A major QTL located on bin 8.03 was consistently detected with the largest phenotypic explained variation: 13% in association‐mapping analysis and 13.18 to 43.31% in linkage‐mapping analysis. These results indicated that TSC resistance in maize was controlled by a major QTL located on bin 8.03 and several minor QTL with smaller effects on other chromosomes. Genomic prediction results showed moderate‐to‐high prediction accuracies in different populations using various training population sizes and marker densities. Prediction accuracy of TSC resistance was >0.50 when half of the population was included into the training set and 500 to 1,000 SNPs were used for prediction. Information obtained from this study can be used for developing functional molecular markers for marker‐assisted selection (MAS) and for implementing genomic selection (GS) to improve TSC resistance in tropical maize.

New Insights on Planet Formation in WASP-47 from a Simultaneous Analysis of Radial Velocities and Transit Timing Variations

Measuring precise planet masses, densities, and orbital dynamics in individual planetary systems is an important pathway toward understanding planet formation. The WASP-47 system has an unusual architecture that motivates a complex formation theory. The system includes a hot Jupiter (“b”) neighbored by interior (“e”) and exterior (“d”) sub-Neptunes, and a long-period eccentric giant planet (“c”). We simultaneously modeled transit times from the Kepler
K2 mission and 118 radial velocities to determine the precise masses, densities, and Keplerian orbital elements of the WASP-47 planets. Combining RVs and TTVs provides a better estimate of the mass of planet d (

) than that obtained with only RVs (

) or TTVs (

). Planets e and d have high densities for their size, consistent with a history of photoevaporation and/or formation in a volatile-poor environment. Through our RV and TTV analysis, we find that the planetary orbits have eccentricities similar to the solar system planets. The WASP-47 system has three similarities to our own solar system: (1) the planetary orbits are nearly circular and coplanar, (2) the planets are not trapped in mean motion resonances, and (3) the planets have diverse compositions. None of the current single-process exoplanet formation theories adequately reproduce these three characteristics of the WASP-47 system (or our solar system). We propose that WASP-47, like the solar system, formed in two stages: first, the giant planets formed in a gas-rich disk and migrated to their present locations, and second, the high-density sub-Neptunes formed in situ in a gas-poor environment.
Binary Black Hole Mergers from Field Triples: Properties, Rates, and the Impact of Stellar Evolution
Authors: Antonini Fabio , Toonen Silvia , Hamers Adrian S.
Published: May 2017

We consider the formation of binary black hole (BH) mergers through the evolution of field massive triple stars. In this scenario, favorable conditions for the inspiral of a BH binary are initiated by its gravitational interaction with a distant companion, rather than by a common-envelope phase invoked in standard binary evolution models. We use a code that follows self-consistently the evolution of massive triple stars, combining the secular triple dynamics (Lidov–Kozai cycles) with stellar evolution. After a BH triple is formed, its dynamical evolution is computed using either the orbit-averaged equations of motion, or a high-precision direct integrator for triples with weaker hierarchies for which the secular perturbation theory breaks down. Most BH mergers in our models are produced in the latter non-secular dynamical regime. We derive the properties of the merging binaries and compute a BH merger rate in the range (0.3–1.3) Gpc−3 yr−1, or up to ≈2.5 Gpc−3 yr−1 if the BH orbital planes have initially random orientation. Finally, we show that BH mergers from the triple channel have significantly higher eccentricities than those formed through the evolution of massive binaries or in dense star clusters. Measured eccentricities could therefore be used to uniquely identify binary mergers formed through the evolution of triple stars. While our results suggest up to ≈10 detections per year with Advanced-LIGO, the high eccentricities could render the merging binaries harder to detect with planned space based interferometers such as LISA.

The range of currently proposed active galactic nucleus (AGN) far-infrared templates results in uncertainties in retrieving host galaxy information from infrared observations and also undermines constraints on the outer part of the AGN torus. We discuss how to test and reconcile these templates. Physically, the fraction of the intrinsic AGN IR-processed luminosity compared with that from the central engine should be consistent with the dust-covering factor. In addition, besides reproducing the composite spectral energy distributions (SEDs) of quasars, a correct AGN IR template combined with an accurate library of star-forming galaxy templates should be able to reproduce the IR properties of the host galaxies, such as the luminosity-dependent SED shapes and aromatic feature strengths. We develop tests based on these expected behaviors and find that the shape of the AGN intrinsic far-IR emission drops off rapidly starting at ∼20 μm and can be matched by an Elvis et al.-like template with a minor modification. Despite the variations in the near- to mid-IR bands, AGNs in quasars and Seyfert galaxies have remarkably similar intrinsic far-IR SEDs at λ ∼ 20–100 μm, suggesting a similar emission character of the outermost region of the circumnuclear torus. The variations of the intrinsic AGN IR SEDs among the type-1 quasar population can be explained by the changing relative strengths of four major dust components with similar characteristic temperatures, and there is evidence for compact AGN-heated dusty structures at sub-kiloparsec scales in the far-IR.

Protogalactic environments are typically identified using quasar absorption lines and can manifest as Damped Lyman-alpha Absorbers (DLAs) and Lyman Limit Systems (LLSs). We use radio observations of Faraday effects to test whether these galactic building blocks host a magnetized medium, by combining DLA and LLS detections with 1.4 GHz polarization data from the NRAO VLA Sky Survey (NVSS). We obtain a control, a DLA, and an LLS sample consisting of 114, 19, and 27 lines of sight, respectively. Using a Bayesian framework and weakly informative priors, we are unable to detect either coherent or random magnetic fields in DLAs: the regular coherent fields must be

μG, and the lack of depolarization suggests the weakly magnetized gas in DLAs is non-turbulent and quiescent. However, we find a mild suggestive indication that LLSs have coherent magnetic fields, with a 71.5% probability that LLSs have higher

than a control, although this is sensitive to the redshift distribution. We also find a strong indication that LLSs host random magnetic fields, with a 95.5% probability that LLS lines of sight have lower polarized fractions than a control. The regular coherent fields within the LLSs must be

μG, and the magnetized gas must be highly turbulent with a typical turbulent length scale on the order of ≈5–20 pc. Our results are consistent with the standard dynamo paradigm, whereby magnetism in protogalaxies increases in coherence over cosmic time, and with a hierarchical galaxy formation scenario, with the DLAs and LLSs exploring different stages of magnetic field evolution in galaxies.

We present hydrodynamic simulations of gas clouds inflowing from the disk to a few hundred parsec region of the Milky Way. A gravitational potential is generated to include realistic Galactic structures by using thousands of multipole expansions (MEs) that describe 6.4 million stellar particles of a self-consistent Galaxy simulation. We find that a hybrid ME model, with two different basis sets and a thick-disk correction, accurately reproduces the overall structures of the Milky Way. Through non-axisymmetric Galactic structures of an elongated bar and spiral arms, gas clouds in the disk inflow to the nuclear region and form a central molecular zone-like nuclear ring. We find that the size of the nuclear ring evolves into

, regardless of the initial size. For most simulation runs, the rate of gas inflow to the nuclear region is equilibrated to

. The nuclear ring is off-centered, relative to the Galactic center, by the lopsided central mass distribution of the Galaxy model, and thus an asymmetric mass distribution of the nuclear ring arises accordingly. The vertical asymmetry of the Galaxy model also causes the nuclear ring to be tilted along the Galactic plane. During the first ∼100 Myr, the vertical frequency of the gas motion is twice that of the orbital frequency, thus the projected nuclear ring shows a twisted,

. The overall youth of these 19 mid-K to early-M stars is readily apparent from their positions relative to the loci of main-sequence stars and giants in Gaia-based color-magnitude and color-color diagrams constructed for all stars detected by Galex and the Wide-field Infrared Space Explorer for which parallax measurements are included in DR1. The isochronal ages of all 19 stars lie in the range ∼10–100 Myr. Comparison with Li-based age estimates indicates a handful of these stars may be young main-sequence binaries rather than pre-main sequence stars. Nine of the 19 objects have not previously been considered as nearby, young stars, and all but one of these are found at declinations north of +30°. The Gaia DR1 results presented here indicate that the GALNYSS sample includes several hundred nearby, young stars, a substantial fraction of which have not been previously recognized as having ages

Variation of Supergranule Parameters with Solar Cycles: Results from Century-long Kodaikanal Digitized Ca ii K Data
Authors: Chatterjee Subhamoy , Mandal Sudip , Banerjee Dipankar
Published: May 2017

The Ca ii K spectroheliograms spanning over a century (1907–2007) from Kodaikanal Solar Observatory, India, have recently been digitized and calibrated. Applying a fully automated algorithm (which includes contrast enhancement and the “Watershed method”) to these data, we have identified the supergranules and calculated the associated parameters, such as scale, circularity, and fractal dimension. We have segregated the quiet and active regions and obtained the supergranule parameters separately for these two domains. In this way, we have isolated the effect of large-scale and small-scale magnetic fields on these structures and find a significantly different behavior of the supergranule parameters over solar cycles. These differences indicate intrinsic changes in the physical mechanism behind the generation and evolution of supergranules in the presence of small-scale and large-scale magnetic fields. This also highlights the need for further studies using solar dynamo theory along with magneto-convection models.
Variatio delectat : variation et dialinguistique
Authors: Gadet Françoise
Published: May 2017

Cet article s’intéresse au concept de variation , popularisé en sociolinguistique par le variationnisme. La notion de variation constitue toujours aujourd’hui un concept-clé en sociolinguistique. Après avoir montré la double orientation possible (vers le système ou vers le locuteur), on passe au crible de la critique les implications des termes en jeu (en particulier variété ). On cherche à établir qu’il serait souhaitable que la sociolinguistique variationnelle, afin de satisfaire à la fois des descriptions de faits variables et des explications de la variation, trouve moyen de tenir compte en même temps des deux orientations, dans ce qu’on pourrait appeler le domaine de la dialinguistique.
Faut-il se débarrasser des « idéologies linguistiques »?
Authors: Costa James
Published: May 2017

Cet article part du constat que la notion d’idéologies linguistiques est utilisée de plus en plus fréquemment en sociolinguistique, sans que cet usage ne soit réellement problématisé ou justifié. S’agit-il donc simplement d’un effet de mode, auquel cas ne devrions-nous pas abandonner cette notion ? Ce texte cherche à montrer que l’usage actuel des idéologies linguistiques ne dérive généralement pas, ou peu, d’une conceptualisation qui aurait ses origines dans la sociologie critique européenne, mais dans une réflexion sémiotique et anthropologique dont les origines remontent aux années 1970 et à la relecture de l’œuvre de C. S. Peirce. En montrant les possibilités qu’offre cette sémiotique, notamment en termes de prise en compte des objets dans leur matérialité, cet article propose de conserver la notion d’idéologies linguistiques – à condition qu’elle soit accompagnée d’une véritable réflexion sur son usage. C’est à cette seule condition que le terme ne sera pas un simple synonyme de « représentations » ou de « idées ».
Parcours en analyse du discours
Authors: Maingueneau Dominique
Published: May 2017

Dans cette contribution, je commence par réfléchir sur l’évolution de l’analyse du discours en m’appuyant sur mon parcours personnel, qui a accompagné l’institutionnalisation progressive de ce champ de recherche. Dans un second temps, je m’efforce de mettre à jour un certain nombre de défis auxquels elle est aujourd’hui confrontée : quatre questions sont abordées : a) l’étude du discours est fragmentée en de multiples courants, mais il est très difficile d’appréhender ce champ dans sa globalité ; 2) l’analyse du discours est confrontée aux transformations provoquées par le développement d’Internet qui tout à la fois offre des objets inédits à l’analyse et modifie en profondeur les conditions de la recherche et ; 3) l’analyse du discours a traditionnellement privilégie les données extraites de conversations ordinaires, des médias, de l’éducation, la santé ou la politique, ce qui a une incidence forte sur ses présupposés, ses concepts et ses méthodes ; il paraît nécessaire de s’intéresser à de nouveaux corpus ; 4) l’analyse du discours a émergé à travers différentes cultures scientifiques nationales : que se passe-t-il quand l’espace de la recherche est mondialisé ?
Nouveaux défis pour l’analyse conversationnelle : l’organisation située et systématique de l’interaction sociale
Authors: Mondada Lorenza
Published: May 2017

À la croisée entre linguistique et sociologie, l’analyse conversationnelle a depuis les années 1970 offert un modèle pour l’analyse du langage et de l’action dans l’interaction sociale. Cet article en retrace les principes fondateurs et quelques défis contemporains. Sur la base d’une analyse empirique d’un corpus vidéo sont ensuite présentés les enjeux de la multimodalité, de ses temporalités multiples, de l’imbrication des formats verbaux de l’action et de leur ancrage social, ainsi que de la tension entre recherche de la systématicité et respect des variations et de l’indexicalité.
