PLASMA BETA DEPENDENCE OF THE ION-SCALE SPECTRAL BREAK OF SOLAR WIND TURBULENCE: HIGH-RESOLUTION 2D HYBRID SIMULATIONS
Authors: Franci Luca , Landi Simone , Matteini Lorenzo , Verdini Andrea , Hellinger Petr 
Published: December 2016

ABSTRACT
We investigate properties of the ion-scale spectral break of solar wind turbulence by means of two-dimensional high-resolution hybrid particle-in-cell simulations. We impose an initial ambient magnetic field perpendicular to the simulation box and add a spectrum of in-plane, large-scale, magnetic and kinetic fluctuations. We perform a set of simulations with different values of the plasma β, distributed over three orders of magnitude, from 0.01 to 10. In all cases, once turbulence is fully developed, we observe a power-law spectrum of the fluctuating magnetic field on large scales (in the inertial range) with a spectral index close to −5/3, while in the sub-ion range we observe another power-law spectrum with a spectral index systematically varying with β (from around −3.6 for small values to around −2.9 for large ones). The two ranges are separated by a spectral break around ion scales. The length scale at which this transition occurs is found to be proportional to the ion inertial length, d

i
, for β ≪ 1 and to the ion gyroradius,

, for β ≫ 1, i.e., to the larger between the two scales in both the extreme regimes. For intermediate cases, i.e., β ∼ 1, a combination of the two scales is involved. We infer an empiric relation for the dependency of the spectral break on β that provides a good fit over the whole range of values. We compare our results with in situ observations in the solar wind and suggest possible explanations for such a behavior.
IONIZATION AND DUST CHARGING IN PROTOPLANETARY DISKS
Authors: Ivlev A. V. , Akimkin V. V. , Caselli P. 
Published: December 2016

ABSTRACT
Ionization–recombination balance in dense interstellar and circumstellar environments is a key factor for a variety of important physical processes, such as chemical reactions, dust charging and coagulation, coupling of the gas with magnetic field, and development of instabilities in protoplanetary disks. We determine a critical gas density above which the recombination of electrons and ions on the grain surface dominates over the gas-phase recombination. For this regime, we present a self-consistent analytical model, which allows us to calculate exactly the abundances of charged species in dusty gas, without making assumptions on the grain charge distribution. To demonstrate the importance of the proposed approach, we check whether the conventional approximation of low grain charges is valid for typical protoplanetary disks, and discuss the implications for dust coagulation and development of the “dead zone” in the disk. The presented model is applicable for arbitrary grain-size distributions and, for given dust properties and conditions of the disk, has only one free parameter—the effective mass of the ions, shown to have a small effect on the results. The model can be easily included in numerical simulations following the dust evolution in dense molecular clouds and protoplanetary disks.
THE HAWAII INFRARED PARALLAX PROGRAM. II. YOUNG ULTRACOOL FIELD DWARFS*

†
Authors: Liu Michael C. , Dupuy Trent J. , Allers Katelyn N. 
Published: December 2016

ABSTRACT
We present a large, uniform analysis of young (≈10–150 Myr) ultracool dwarfs, based on new high-precision infrared (IR) parallaxes for 68 objects. We find that low-gravity (vl-g) late-M and L dwarfs form a continuous sequence in IR color–magnitude diagrams, separate from the field population and from current theoretical models. These vl-g objects also appear distinct from young substellar (brown dwarf and exoplanet) companions, suggesting that the two populations may have a different range of physical properties. In contrast, at the L/T transition, young, old, and spectrally peculiar objects all span a relatively narrow range in near-IR absolute magnitudes. At a given spectral type, the IR absolute magnitudes of young objects can be offset from ordinary field dwarfs, with the largest offsets occurring in the Y and J bands for late-M dwarfs (brighter than the field) and mid-/late-L dwarfs (fainter than the field). Overall, low-gravity (vl-g) objects have the most uniform photometric behavior, while intermediate gravity (int-g) objects are more diverse, suggesting a third governing parameter beyond spectral type and gravity class. We examine the moving group membership for all young ultracool dwarfs with parallaxes, changing the status of 23 objects (including 8 previously identified planetary-mass candidates) and fortifying the status of another 28 objects. We use our resulting age-calibrated sample to establish empirical young isochrones and show a declining frequency of vl-g objects relative to int-g objects with increasing age. Notable individual objects in our sample include high-velocity (≳100 km s−1) int-g objects, very red late-L dwarfs with high surface gravities, candidate disk-bearing members of the MBM20 cloud and β Pic moving group, and very young distant interlopers. Finally, we provide a comprehensive summary of the absolute magnitudes and spectral classifications of young ultracool dwarfs, using a combined sample of 102 objects found in the field and as substellar companions to young stars.

ABSTRACT
We present maps of the Large and Small Magellanic Clouds from combined South Pole Telescope (SPT) and Planck data. The Planck satellite observes in nine bands, while the SPT data used in this work were taken with the three-band SPT-SZ camera, The SPT-SZ bands correspond closely to three of the nine Planck bands, namely those centered at 1.4, 2.1, and 3.0 mm. The angular resolution of the Planck data ranges from 5 to 10 arcmin, while the SPT resolution ranges from 1.0 to 1.7 arcmin. The combined maps take advantage of the high resolution of the SPT data and the long-timescale stability of the space-based Planck observations to deliver robust brightness measurements on scales from the size of the maps down to ∼1 arcmin. In each band, we first calibrate and color-correct the SPT data to match the Planck data, then we use noise estimates from each instrument and knowledge of each instrument’s beam to make the inverse-variance-weighted combination of the two instruments’ data as a function of angular scale. We create maps assuming a range of underlying emission spectra and at a range of final resolutions. We perform several consistency tests on the combined maps and estimate the expected noise in measurements of features in them. We compare maps from this work to those from the Herschel HERITAGE survey, finding general consistency between the data sets. All data products described in this paper are available for download from the NASA Legacy Archive for Microwave Background Data Analysis server.

Le développement cognitif et socio-émotionnel est particulièrement altéré chez les enfants avec trouble du spectre de l’autisme (TSA) qui ont un très faible niveau de développement (entre 4 mois et 24 mois). La question est de savoir si cette altération développementale est identique selon l’âge de l’enfant et son degré de retard ou de déficience intellectuelle. L’étude porte sur 69 enfants issus de 7 pays (9 filles et 60 garçons) répartis en deux groupes d’âge réel, avec soit un retard léger, soit une déficience intellectuelle sévère (Groupe 1 : N = 39 ; 1 an 7 mois-3 ans et QD moyen 60 = ; et Groupe 2 : N = 30 ; 8 ans-14 ans et QD moyen = 15). Le développement est évalué à l’aide de la Batterie d’évaluation cognitive et socio-émotionnelle (BECS). Si on ne note aucune différence significative entre les niveaux de développement global, cognitif et socio-émotionnel des deux groupes, les plus jeunes enfants avec TSA présentent une plus grande hétérogénéité socio-émotionnelle. Par ailleurs, il existe des différences pour les domaines « relation affective » et « interaction sociale » (les niveaux sont plus élevés chez les enfants les plus jeunes) et « image de soi » et « imitation gestuelle » (les niveaux sont plus élevés chez les enfants les plus âgés). Les implications pour les pratiques d’évaluation et d’intervention en fonction de l’âge et du degré de retard de l’enfant sont abordées.
Les SES au pied de la lettre
Authors: Giraud Frédérique , Martinache Igor 
Published: December 2016

Comment les sciences économiques et sociales lisent-elles la littérature ? Quels usages peuvent-elles en faire ? Qu’est-ce que la littérature peut apporter de spécifique aux SES ? Le dossier présenté dans ce numéro propose quelques éléments de réponse à ces questions, s’efforçant ainsi de construire des ponts entre des mondes qui seraient tentés de s’ignorer, les sciences sociales cherchant leur scientificité hors de la littérature.
Marcel Proust et la sociologie
Authors: Dubois Jacques 
Published: December 2016

Proust se met à rédiger À la recherche du temps perdu dans les années qui voient une nouvelle discipline savante prendre forme en France avec Émile Durkheim et Gabriel Tarde : la sociologie. Proust connaît son existence puisqu’il la mentionne à trois reprises dans son roman. Mais, si rien ne laisse croire qu’il s’est inspiré des deux fondateurs, le point de vue qu’il porte en romancier sur la société rejoint le leur à plusieurs endroits. Mieux : dans la Recherche , Proust annonce une sociologie à venir.
À quoi sert la théorie politique ?
Authors: Boudou Benjamin 
Published: December 2016

Résumé Cet article part du constat d’un manque de légitimité de la théorie politique afin de mieux en souligner l’intérêt pour la science politique et les sciences humaines. Dans un premier temps, l’auteur présente un état des lieux des recrutements et thèses soutenues en théorie politique pour montrer sa situation minoritaire et la défiance dont elle fait l’objet. Puis, en interrogeant le rapport entre théorie et politique, l’auteur pose le problème de l’utilité de la discipline vis-à-vis de sciences sociales et de la société civile. L’auteur défend la pertinence de la théorie à partir des fonctions qu’elle doit remplir : une fonction heuristique, une fonction pédagogique, une fonction critique et une fonction éthique.
L’ effet de frontière dans les mobilisations collectives de migrants en situation administrative précaire
Authors: Deleixhe Martin , Vertongen Youri Lou 
Published: December 2016

Dans les théories post-nationales de la démocratie, les migrants occupent souvent une place de choix comme acteurs du renouveau de la contestation politique. Condamné pour une partie d’entre eux à une extrême précarité juridique et sociale par leur exclusion étatique, les mobilisations collectives de migrants revendiquant la régularisation de leur situation administrative sont alors présentées comme la figure de proue d’une citoyenneté transnationale innovante. Sur la base de deux observations participantes menées au sein de mouvements de sans-papiers, nous soumettons à l’examen l’hypothèse selon laquelle la frontière est cependant bien plus résiliente que ne le pensent les démocrates postnationaux. Car la frontière se reproduit sous la forme de distinctions proto-administratives jusque dans les endroits où l’on attend le moins, et notamment au sein des mouvements de lutte de migrants, par un phénomène que nous nommerons un « effet de frontière ». Cet article avancera d’une part que cet effet de frontière est un avatar de la « pensée d’État » telle qu’elle a été mise en évidence par Bourdieu et le mobilisera d’autre part pour fournir un début d’explication à l’extrême fragmentation des groupes de migrants en lutte.
Webactivism and the dynamics of consumerist resistance : Analytical framework and experimental study
Authors: Bouille Julien , Robert-Demontrond Philippe 
Published: December 2016

Cet article s’intéresse à une forme particulière et nouvelle d’activisme : le Webactivisme. Nous désignons par ce terme l’ensemble des stratégies de communication militantes qui sont exclusivement conçues et diffusées depuis les plateformes Web 2.0. L’objectif de cette recherche est double. Il s’agit en premier lieu de montrer que le Webactivisme répond de manière efficace aux défis organisationnels auxquels les collectifs de consommateurs militants sont d’ordinaire confrontés. Dans cette perspective, nous construisons une grille de lecture de la résistance consumériste sous l’angle de ses ressorts organisationnels. Trois niveaux d’analyse sont proposés pour rendre compte de cette articulation : les micro-tactiques, les macro-politiques et enfin les méso-dynamiques de la résistance, niveau au sein duquel le Webactivisme apparaît central. En second lieu, nous questionnons l’influence de ce Webactivisme sur les consommateurs en examinant pour cela le rôle particulier de la source Web dans la diffusion de messages persuasifs et la mise en œuvre d’actions militantes de terrain comme le « buycott ». Nous testons ainsi, par une expérimentation, l’impact de la crédibilité de la source Web et du type de plateforme, d’une part, sur l’acceptation des messages militants et, d’autre part, sur les intentions comportementales de résistance des consommateurs (intention de « buycott », de rediffusion de l’information et de re-consultation du site). Les résultats montrent que si la crédibilité de la source Web agit positivement sur le degré d’accord au message et sur les intentions de revisite de la plateforme, elle n’exerce en revanche aucune influence sur l’intention de « buycott » et de rediffusion de l’information. Le type de plateforme ne dispose d’aucun impact sur nos variables dépendantes.
La représentation des sens modaux dans trois langues romanes : le français, l’italien et le roumain. Du qualitatif au quantitatif et retour

Published: December 2016

Résumé	Cette étude se propose d’analyser, au moyen d’une recherche quantitative sur corpus, la fréquence de certaines formes véhiculant les sens modaux épistémique et concessif dans trois langues romanes : le français, l’italien et le roumain. Partant de l’observation que les mêmes formes véhiculent des sens modaux différents d’une langue à l’autre, nous mettons en évidence les points de proximité et de divergence dans l’actualisation de ces sens dans les trois langues considérées. Notre objectif est de fournir des pistes pour rendre compte de la répartition des sens modaux dans le lexique d’une langue ainsi que des facteurs qui favorisent le développement de ces sens sur certaines formes de la langue au détriment d’autres.
Varying effects of EGF, HGF and TGFβ on formation of invadopodia and invasiveness of melanoma cell lines of different origin
Authors: Makowiecka A. , Simiczyjew A. , Nowak D. , Mazur A.J. 
Published: December 2016

<p>The understanding of melanoma malignancy mechanisms is essential for patient survival, because melanoma is responsible for ca. 75% of deaths related to skin cancers. Enhanced formation of invadopodia and extracellular matrix (ECM) degradation are two important drivers of cell invasion, and actin dynamics facilitate protrusive activity by providing a driving force to push through the ECM. We focused on the influence of epidermal growth factor (EGF), hepatocyte growth factor (HGF) and transforming growth factor β (TGFβ) on melanoma cell invasiveness, since they are observed in the melanoma microenvironment. All three factors stimulated invasion of A375 and WM1341D cells derived from primary tumor sites. In contrast, only EGF and HGF stimulated invasion of WM9 and Hs294T cells isolated from lymph node metastases. Enhanced formation of invadopodia and ECM degradation underlie the increased amount of invasive cells after stimulation with the tested agents. Generally, a rise in invasive potential was accompanied by a decrease in actin polymerization state (F:G ratio). The F:G ratio remained unchanged or was even increased in metastatic cell lines treated with TGFβ. Our findings indicate that the effects of stimulation with EGF, HGF and TGFβ on melanoma cell invasiveness could depend on melanoma cell progression stage. </p>
Efficacy of a 4-week yogic lifestyle education for promoting holistic health in Indian school adolescents
Authors: Singh Arun Pratap 
Published: December 2016

Context:
Need for yogic lifestyle education in schools is being recognized eloquently. However, effectiveness of yogic lifestyle for enhancing adolescent health in schools remains partially or minimally attempted.

Aims:
To examine the relevance of yogic lifestyle education in improving holistic aspects of adolescent health in schools.

Method:
A four week field experiment was conducted among a sample of 100 students enrolled in a residential school located in a semi-urban setting by using a 2 (control and intervention group) ×2 (male and female students) ×2 (pre and post-test) factorial design. Standardized self-report adolescent health questionnaires were used before and after yogic lifestyle education to assess its holistic effects.

Results:
ANOVA was used to analyze efficacy of yogic lifestyle education in promoting different aspects of adolescent health. Results revealed that yogic lifestyle education group participants' responses displayed significantly greater enhancement on a variety of self-reported positive health outcomes and a reduction on different negative health outcomes than the control group participants.

Conclusions:
Yogic lifestyle education programme has promising potential to not only reduce health problems but also enhance positive aspects of health in school going adolescents.
Nyasa – A scientific study
Authors: Bashyam Sarangapani , Srinivasan T. M. , Nagendra Hongasandra Ramarao 
Published: December 2016

Background:
Divine worship follows Veda or agama sastras (liturgy) in Hindu lore. Nyasa is a mandatory procedure before every mantra japa (repetition of a mantra) as per agama sastra. In nyasa, the individual places parts of the mantra in designated parts of the body in a sequential order before performing japa.

Aims:
The aims of this study are to understand the concept and the diverse practices and to gather scientific evidence of the benefits to the body-mind-intellect of an individual doing mantra japa with nyasa.

Method:
Literature available on the subject was studied. Controlled experiments on a limited scale were performed using Electrophotonic Imaging (EPI) device with participants from a Vedic institution, performing daily Gayatri japa (recitation of the most popular mantra) with self as control and cross-over design. EPI was used to measure three parameters, namely integral entropy, integral area, and fractality.

Results:
Qualitative outcome of the study is described. Marginal improvements in integral entropy (decrease) and integral area (increase) were observed. Both signify positive outcome due to nyasa compared with relaxation by the control group. There was no noticeable difference in fractality between the two groups.

Conclusion:
Because decrease in entropy and increase in integral area are associated with better health, the study can be extended to larger and heterogeneous samples and over longer periods of nyasa practice for more conclusive results.

Authors: Bhate Niranjana H. 
Published: December 2016

Context:
Ādi Śaṅkāracārya was an exponent of Advaita Vedānta philosophy. It is well-known that he preached Jñāna Yoga or the path of knowledge for attainment of liberation. However, very few people are aware of the fact that Ādi Śaṅkāracārya has mentioned various methods or types of yoga for liberation depending on the dispositions of the aspirants. Study of his unpopular works reveal this fact.

Aim:
The aim of this paper is to present various types of yoga discussed in the works of Ādi Śaṅkāracārya.

Method:
A descriptive method of analyzing arguments is used because of the philosophico-literary nature of the study.

Result:
Ādi Śaṅkāracārya has stated various types of yoga such as Bhakti Yoga, Rāja Yoga, Haṭha Yoga, and Tantra Yoga as a means to Jñāna Yoga.

Conclusion:
Study of Ādi Śaṅkāracārya's work reveals that Bhakti Yoga, Rāja Yoga Haṭha Yoga, and Tantra Yoga are a means to knowledge or Jñāna Yoga for the attainment of emancipation.
Effects of yogic practices on total cholesterol and triglyceride among obese women
Authors: Malarvizhi V. , Elangovan R. 
Published: December 2016

Context:
Obesity has been globally recognized as a risk factor for human health. It not only affects our health but also challenges our emotions and behavioral patterns. It is a significant problem among Indian women because many of them are homemakers and have sedentary lifestyle. Therefore, there is a growing urgency to counter obesity among women.

Aim:
The objective of the study was to find out the effect of yogic practices on cholesterol and triglyceride levels among obese women. It was hypothesized that yogic practices would significantly decrease total cholesterol and triglyceride levels among obese women in comparison to the control group.

Method:
The study consisted of yoga and control group, each containing twenty obese women randomly selected from Mogappair (Chennai). The yoga program was conducted three days a week (50–60 min/day) for twelve weeks. Cholesterol and triglycerides were tested on both groups at zero time and after 12 weeks, and the data were analyzed with independent t-test.

Results:
The post-test mean value of total cholesterol (193.4 mg/dL) and triglyceride (144.9 mg/dL) of the yoga group considerably reduced with respect to the corresponding mean value of post-test total cholesterol (213.1 mg/dL) and triglyceride level (167.8 mg/dL) of the control group. The independent t-test indicated that the total cholesterol (p < 0.05) and triglyceride (p < 0.05) levels were significantly decreased in the yoga group after twelve weeks of yogic practices.

Conclusion:
Regular practice of yoga significantly improved the health condition of obese women by decreasing total cholesterol and triglyceride.
