Género, sexualidad y transición subjetiva en México: construcción de la adolescencia femenina en las celebraciones de 15 años
Authors: Gutiérrez Domínguez Lisett María 
Published: March 2017

En el presente artículo se discute el tema de la articulación entre el género, la edad y la clase social en los procesos de construcción subjetiva que ocurren durante el tránsito de la infancia a la adolescencia. A partir de la relación entre los conceptos de posiciones de sujeto, interpelación, performatividad y cita, se analiza cómo esta transición para las adolescentes mexicanas es asociada con la celebración de los 15 años, a pesar de que muchas familias rechazan el patrón de fiesta típica y las normas de género vinculadas a ese patrón. Como material empírico para la discusión, se presentan dos casos de quinceañeras que, aunque no hacen una fiesta típica, tanto ellas como sus familiares se sienten interpeladas por la llegada de los 15 años, reconocen la existencia de una tradición asociada a este momento de la vida, manifiestan algún tipo de rechazo a dicha tradición, debaten acerca de formas alternativas de celebrar, y facilitan procesos de transición subjetiva hacia la feminidad adolescente, o bien, se resisten a ellos, postergándolos.
Planificar la exclusión de los hombres de la planificación familiar: un estudio de caso en México
Authors: Gutmann Matthew 
Published: March 2017

No hay ningún lugar en el mundo donde participen más hombres que mujeres en la anticoncepción. A medida que se ha ampliado en el ámbito internacional la disponibilidad de métodos anticonceptivos altamente efectivos para mujeres, y que en las últimas décadas las mujeres se han convertido en el objetivo crucial de las campañas de planificación familiar, las decisiones sobre el control de la natalidad ocurren cada vez más en una cultura anticonceptiva femenina. Se ha marginado involuntariamente a los hombres de la responsabilidad para prevenir el embarazo y en ello han estado involucradas la industria farmacéutica trasnacional, los organismos nacionales de planificación familiar, las instituciones religiosas y los organismos y fundaciones de ayuda multilateral. En Oaxaca, la baja tasa de participación masculina en la anticoncepción está determinada por las estructuras e ideologías globales articuladas en la premisa, legitimada por tópicos biológicos inadecuados, de que la sexualidad masculina y la femenina son dicotómicas.
Las niñas buenas no gritan: anorexia y desafíos a la feminidad en jóvenes mujeres de León, Guanajuato
Authors: Hernández Gutiérrez Julia 
Published: March 2017

Desde un cruce entre los estudios de juventud y género, se sugiere una interpretación de la anorexia nerviosa relacionada particularmente con la vida y experiencias de las mujeres jóvenes que sufren de este trastorno de la alimentación, teniendo en cuenta su edad, así como las demandas de género que experimentan. Se cuestiona que las jóvenes con anorexia se ajusten dócil y silenciosamente ?como es "propio de su género"? a los requerimientos sociales y de su entorno inmediato, relacionados con el apego a cierto ideal estético y al mantenimiento de una actitud propia de una "señorita". En este artículo se propone, por el contrario, que la anorexia puede implicar formas de resistir a las exigencias del entorno, lo que muestra la ironía de las fachadas y la rabia que puede haber en un cuerpo, parentemente, delicado. El presente trabajo se funda en una investigación realizada en León, Guanajuato.

Phases d'effondrements aux grottes préhistoriques : du Würm à l'Holocène dans le Midi de la France
Authors: Blanc Jean-Joseph 
Published: March 2017

Sequences of collapses from Würm to Holocen in prehistoric caves (South-East of France)
Multivariates methods (factorial and discriminant analysis) applied to many accurate stratigraphy and sedimentary sequences files deal just-dated cave-collapses observed into cavity and rock-shelters at the SE of France, show some detailled interpretations about the mechanism inducing the blocks-falls. This work places in a prominent position the various influences relative to cold climates and wet environments, degree of rock fissuration of cave-walls and the sismic-tectonic impacts.
Test of Weak Equivalence Principle with the Multi-band Timing of the Crab Pulsar
Authors: Zhang Yueyang , Gong Biping 
Published: March 2017

Abstract
The Weak Equivalent Principle (WEP) can be tested through the parameterized post-Newtonian parameter γ, representing the space curvature produced by unit rest mass. The parameter γ in turn has been constrained by comparing the arrival times of photons originating in distant transient events, such as gamma-ray bursts, fast radio bursts, and giant pulses of pulsars. Those measurements normally correspond to an individual burst event with very limited energy bands and signal-to-noise ratios (S/Ns). In this paper, the discrepancy in the pulse arrival times of the Crab Pulsar between different energy bands is obtained by the phase difference between corresponding pulse profiles. This allows us to compare the pulse arrival times at the largest energy band differences, between radio and optical, radio and X-ray, and radio and gamma-ray respectively. Because the pulse profiles are generated by phase-folding thousands of individual pulses, the time discrepancies between two energy bands are actually measured from thousands of events at each energy band, which corresponds to a much higher S/N. The upper limit of the γ discrepancy set by such an extensively observed and well-modeled source is as follows:

at the energy difference of

,

at the energy difference of

,

at

, and

at

. This actually measures the arrival times of freely falling photons in the gravitational field of the Milky Way with the largest amount of events and with data of the highest S/N, which tests WEP at energy band differences that have never been reached before.
A Simple Analytical Model for Rocky Planet Interiors
Authors: Zeng Li , Jacobsen Stein B. 
Published: March 2017

Abstract
This work aims to explore the scaling relations among rocky exoplanets. The assumption that the internal gravity increases linearly in the core and stays constant in the mantle is tested against numerical simulations, and a simple model is constructed, applicable to rocky exoplanets of CMF (core mass fraction) = 0.2–0.35 and mass = 0.1–30 M
⊕. Various scaling relations are derived: (1) CMF ≈ CRF2 (core radius fraction squared), (2)

(typical interior pressure scales as surface gravity squared), (3) energy released in core formation is

the total gravitational energy, (4) effective heat capacity of the mantle

J K−1, (5) moment of inertia

. These relations, though approximate, are handy for quick use owing to their simplicity and lucidity, and provide insights into the interior structures of those exoplanets.
Protoplanetary Disks as (Possibly) Viscous Disks
Authors: Rafikov Roman R. 
Published: March 2017

Abstract
Protoplanetary disks are believed to evolve on megayear timescales in a diffusive (viscous) manner as a result of angular momentum transport driven by internal stresses. Here we use a sample of 26 protoplanetary disks resolved by ALMA with measured (dust-based) masses and stellar accretion rates to derive the dimensionless α-viscosity values for individual objects, with the goal of constraining the angular momentum transport mechanism. We find that the inferred values of α do not cluster around a single value, but instead have a broad distribution extending from 10−4 to 0.04. Moreover, they correlate with neither the global disk parameters (mass, size, surface density) nor the stellar characteristics (mass, luminosity, radius). However, we do find a strong linear correlation between α and the central mass accretion rate

. This correlation is unlikely to result from the direct physical effect of

on internal stress on global scales. Instead, we suggest that it is caused by the decoupling of stellar

from the global disk characteristics in one of the following ways: (1) The behavior (and range) of α is controlled by a yet-unidentified parameter (e.g., ionization fraction, magnetic field strength, or geometry), ultimately driving the variation of

. (2) The central

is decoupled from the global accretion rate as a result of an instability, or mass accumulation (or loss in a wind or planetary accretion) in the inner disk. (3) Perhaps the most intriguing possibility is that angular momentum in protoplanetary disks is transported nonviscously, e.g., via magnetohydrodynamic winds or spiral density waves.
The Ages of the Thin Disk, Thick Disk, and the Halo from Nearby White Dwarfs
Authors: Kilic Mukremin , Munn Jeffrey A. , Harris Hugh C. , Hippel Ted von , Liebert James W. , Williams Kurtis A. , Jeffery Elizabeth , DeGennaro Steven 
Published: March 2017

Abstract
We present a detailed analysis of the white dwarf luminosity functions derived from the local 40 pc sample and the deep proper motion catalog of Munn et al. Many previous studies have ignored the contribution of thick disk white dwarfs to the Galactic disk luminosity function, which results in an erroneous age measurement. We demonstrate that the ratio of thick/thin disk white dwarfs is roughly 20% in the local sample. Simultaneously fitting for both disk components, we derive ages of 6.8–7.0 Gyr for the thin disk and 8.7 ± 0.1 Gyr for the thick disk from the local 40 pc sample. Similarly, we derive ages of 7.4–8.2 Gyr for the thin disk and 9.5–9.9 Gyr for the thick disk from the deep proper motion catalog, which shows no evidence of a deviation from a constant star formation rate in the past 2.5 Gyr. We constrain the time difference between the onset of star formation in the thin disk and the thick disk to be

Gyr. The faint end of the luminosity function for the halo white dwarfs is less constrained, resulting in an age estimate of

Gyr for the Galactic inner halo. This is the first time that ages for all three major components of the Galaxy have been obtained from a sample of field white dwarfs that is large enough to contain significant numbers of disk and halo objects. The resultant ages agree reasonably well with the age estimates for the oldest open and globular clusters.

Abstract
We present a large-scale combination of near-infrared (near-IR) interstellar polarization data from background starlight with polarized emission data at submillimeter wavelengths for the Vela C molecular cloud. The near-IR data consist of more than 6700 detections probing a range of visual extinctions between 2 and

in and around the cloud. The submillimeter data were collected in Antarctica by the Balloon-borne Large Aperture Submillimeter Telescope for Polarimetry. This is the first direct combination of near-IR and submillimeter polarization data for a molecular cloud aimed at measuring the “polarization efficiency ratio” (

), a quantity that is expected to depend only on grain-intrinsic physical properties. It is defined as

, where p
500 and p

I
are polarization fractions at

and the I band, respectively, and

is the optical depth. To ensure that the same column density of material is producing both polarization from emission and from extinction, we conducted a careful selection of near-background stars using 2MASS, Herschel, and Planck data. This selection excludes objects contaminated by the Galactic diffuse background material as well as objects located in the foreground. Accounting for statistical and systematic uncertainties, we estimate an average

value of 2.4 ± 0.8, which can be used to test the predictions of dust grain models designed for molecular clouds when such predictions become available. The ratio

appears to be relatively flat as a function of the cloud depth for the range of visual extinctions probed.
The Formation of Magnetic Depletions and Flux Annihilation Due to Reconnection in the Heliosheath
Authors: Drake J. F. , Swisdak M. , Opher M. , Richardson J. D. 
Published: March 2017

Abstract
The misalignment of the solar rotation axis and the magnetic axis of the Sun produces a periodic reversal of the Parker spiral magnetic field and the sectored solar wind. The compression of the sectors is expected to lead to reconnection in the heliosheath (HS). We present particle-in-cell simulations of the sectored HS that reflect the plasma environment along the Voyager 1 and 2 trajectories, specifically including unequal positive and negative azimuthal magnetic flux as seen in the Voyager data. Reconnection proceeds on individual current sheets until islands on adjacent current layers merge. At late time, bands of the dominant flux survive, separated by bands of deep magnetic field depletion. The ambient plasma pressure supports the strong magnetic pressure variation so that pressure is anticorrelated with magnetic field strength. There is little variation in the magnetic field direction across the boundaries of the magnetic depressions. At irregular intervals within the magnetic depressions are long-lived pairs of magnetic islands where the magnetic field direction reverses so that spacecraft data would reveal sharp magnetic field depressions with only occasional crossings with jumps in magnetic field direction. This is typical of the magnetic field data from the Voyager spacecraft. Voyager 2 data reveal that fluctuations in the density and magnetic field strength are anticorrelated in the sector zone, as expected from reconnection, but not in unipolar regions. The consequence of the annihilation of subdominant flux is a sharp reduction in the number of sectors and a loss in magnetic flux, as documented from the Voyager 1 magnetic field and flow data.
Charlson Comorbidity Index Is Related to Organ Damage in Systemic Lupus Erythematosus: Data from KORean lupus Network (KORNET) Registry
Authors: Kim Seong-Kyu , Choe Jung-Yoon , Lee Shin-Seok 
Published: March 2017

Objective.The aim of this study was to identify whether comorbidity status is associated with organ damage in patients with systemic lupus erythematosus (SLE).Methods.A total of 502 patients with SLE enrolled in the KORean lupus Network were consecutively recruited. Data included demographics, age-adjusted Charlson Comorbidity Index (CCIa), disease activity indexes, the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI), the Medical Outcomes Study Short Form-36 health survey (SF-36) score, and the Beck Depression Inventory (BDI) score.Results.Of the total patients, 21.1% (n = 106) experienced organ damage (SDI ≥ 1). Univariate correlation analysis revealed that SDI was not statistically correlated with any clinical variables (correlation coefficient r < 0.3 of all). There were significant differences in the BDI, mental component score of the SF-36, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), CCIa, C-reactive protein, and mean dose of corticosteroid between non-damage (SDI = 0) and damage (SDI ≥ 1) groups. The presence of damage to at least 1 organ in patients with SLE was found to be closely related with higher CCIa, higher SLEDAI, and mean dose of corticosteroid (OR 1.884, 95% CI 1.372–2.586, p < 0.001; OR 1.114, 95% CI 1.041–1.192, p = 0.002; OR 1.036, 95% CI 1.004–1.068, p = 0.026; respectively) in binary logistic regression analysis.Conclusion.This study suggests that organ damage as assessed by the SDI in Korean patients with SLE is related to comorbidities together with disease activity and corticosteroid exposure.
Vater- und Mentorfiguren bei Robert Walser. Dialog, Mimikry und Subversion
Authors: Harrer Konrad 
Published: March 2017

La relation de maints protagonistes walsériens avec leur père ou, plus généralement, avec des personnages susceptibles de constituer des figures paternelles se caractérise par une ambiguïté à plusieurs niveaux. Tandis que les fils, pour la plupart, refusent la mimesis , c’est-à-dire le choix d’une intégration sociale calquée sur celle du père, certains « pères subversifs » apparaissent comme des modèles et des interlocuteurs pour les fils, mais ils deviennent à leur tour victimes d’une mise à distance subversive de la part de ceux-ci. C’est ce que nous nous emploierons à montrer en nous appuyant essentiellement sur Jakob von Gunten.
Une Banque publique ? 1936 ou la mutation initiée de la Banque de France
Authors: Duchaussoy Vincent 
Published: March 2017

Cet article revient sur la loi du 24 juillet 1936 sur la Banque de France, votée par le gouvernement du Front populaire mené par Léon Blum, et sur les transformations durables qu’elle apporta à l’institut d’émission. En modifiant la composition du Conseil général, organe délibératif de la Banque, pour y remplacer les actionnaires les plus influents par des membres nommés par le gouvernement, la loi de 1936 engagea le cycle de la nationalisation de la banque centrale, achevée à la Libération par la prise de propriété du capital par l’État. Si cette transformation répondait à des préoccupations politiques et à la volonté du gouvernement de se prémunir de l’hostilité des puissants actionnaires de la Banque, la croissance de l’influence de l’État dans la gouvernance de l’institution modifia sensiblement les missions de la Banque de France. Celle-ci incarnait désormais un service public de la monnaie qui ne pouvait plus être uniquement déterminé par l’exigence de rentabilité financière et donnait à la Banque un magistère moral sur l’ensemble du système bancaire. De même, la gouvernance interne de la Banque de France, notamment à travers la gestion de son personnel dont le statut sera modifié l’année suivante, se trouva profondément transformée par cette séquence législative, qui renforça notamment la démocratie sociale interne et donna au personnel un statut hybride, à mi-chemin entre la fonction publique et le salariat bancaire.
La société de l’an mil dans le royaume capétien : essai historiographique
Authors: Barthélemy Dominique 
Published: March 2017

La critique constructive de la mutation de l’an mil a débuté en 1992 et 1994 par deux articles de la Revue historique sur le servage et sur la chevalerie, et la présente contribution veut faire le point des développements survenus depuis lors sur ces deux sujets. La question du mariage chrétien a été placée plus au cœur du servage postcarolingien. Mais c’est surtout sur les « chevaliers » que le propos de l’auteur s’est étoffé, grâce à une analyse de la guerre et de l’interaction féodales qui permet de mieux comprendre les enjeux de la vassalité, et surtout le maintien d’une certaine hiérarchie et d’un certain ordre dans la société féodale, favorable à sa reproduction. Rois et princes restent des acteurs essentiels de l’histoire du xi	e siècle, puisque c’est dans leurs cours et maisnies que s’élaborent les idéaux et pratiques de la chevalerie proprement dite. Plus solidaire de la société féodale que ne le pensait la vieille école historienne, l’Église l’est tout de même moins que ne le pensent les tenants actuels du féodalisme ecclésial, auxquels on objecte que les institutions de paix diocésaine sont un véritable effort contre la guerre féodale.
