Published: October 2017

BACKGROUND: Individuals with exceptional longevity and their offspring manifest a lower prevalence of age-related diseases than families without longevity. However, the contribution of dietary habits to protection from disease has not been systematically assessed in families with exceptional longevity. OBJECTIVE: The aim of this study is to compare dietary patterns between individuals with parental longevity and individals without parental longevity. METHODS: Dietary intake was evaluated using the Block Brief Food Frequency Questionnaire in 234 community dwelling Ashkenazi Jewish adults aged 65 years and older who were participants of the LonGenity study, which enrolls the offspring of parents with exceptional longevity (OPEL) and offspring of parents with usual survival (OPUS). RESULTS: OPEL constituted 38% of the subjects. The two groups had similar daily intake of total calories (1119 vs. 1218 kcal, p = 0.83), grams of cholesterol (141 g vs. 143 g, p = 0.19), and grams of sodium (1324 g vs.1475 g, p = 0.45), in OPEL vs. OPUS respectively. There were also no significant differences in the intake of other macronutrients, micronutrients, nutritional supplements and consumption of various food groups between OPEL and OPUS after adjustment for age and sex. DISCUSSION: A healthy diet is associated with a lower risk of several chronic diseases. Our study revealed that dietary intake did not differ between OPEL and OPUS; thus, pointing to the role of longevity genes in protecting from disease among individuals with familial longevity. CONCLUSION: The offspring of long-lived parents do not differ in their dietary patterns compared to individuals without parental longevity.

observations of the HH 111/HH 121 protostellar system. HH 111, with a spectacular collimated optical jet, is one of the most well-known Herbig–Haro objects. We report the detection of a new source, NH3–S, in the vicinity of HH 111/HH 121 (∼0.03 pc from the HH 111 jet source) in two epochs of the ammonia observations. This constitutes the first detection of this source, in a region that has been thoroughly covered previously by both continuum and spectral line interferometric observations. We study the kinematic and physical properties of HH 111 and the newly discovered NH3–S. We also use HCO+ and HCN

data to gain insight into the nature of NH3–S. The chemical structure of NH3–S shows evidence for “selective freeze-out,” an inherent characteristic of dense cold cores. The inner part of NH3–S shows subsonic nonthermal velocity dispersions indicating a “coherent core,” while they increase in the direction of the jets. Archival near- to far-infrared data show no indication of any embedded source in NH3–S. The properties of NH3–S and its location in the infrared dark cloud suggest that it is a starless core located in a turbulent medium, with the turbulence induced by Herbig–Haro jets and associated outflows. More data are needed to fully understand the physical and chemical properties of NH3–S and if/how its evolution is affected by nearby jets.
Observational Signatures of Cloud–Cloud Collision in the Extended Star-forming Region S235
Authors: Dewangan L. K. , Ojha D. K. 
Published: October 2017

Abstract
We present a multi-wavelength data analysis of the extended star-forming region S235 (hereafter E-S235), where two molecular clouds are present. In E-S235, using the 12CO (1–0) and 13CO (1–0) line data, a molecular cloud linked with the site “S235main” is traced in a velocity range [−24, −18] km s−1, while the other one containing the sites S235A, S235B, and S235C (hereafter “S235ABC”) is depicted in a velocity range [−18, −13] km s−1. In the velocity space, these two clouds are separated by ∼4 km s−1, and are interconnected by a lower-intensity intermediate velocity emission, tracing a broad bridge feature. In the velocity channel maps, a possible complementary molecular pair at [−21, −20] km s−1 and [−16, −15] km s−1 is also evident. The sites, “S235ABC,” east 1, and south–west, are spatially seen in the interface of two clouds. Together, these observed features are consistent with the predictions of numerical models of the cloud–cloud collision (CCC) process, favoring the onset of the CCC in E-S235 about 0.5 Myr ago. Deep UKIDSS near-infrared photometric analysis of point-like sources reveals significant clustering of young stellar populations toward the sites located at the junction, and the “S235main.” The sites “S235ABC” harbor young compact H ii regions with dynamical ages of ∼0.06–0.22 Myr, and these sites (including south–west and east 1) also contain dust clumps (having M

). Our observational findings suggest that the star formation activities (including massive stars) appear to be influenced by the CCC mechanism at the junction.
Search for a Signature of Interaction between Relativistic Jet and Progenitor in Gamma-Ray Bursts

Published: October 2017

Abstract
The time variability of prompt emission in gamma-ray bursts (GRBs) is expected to originate from the temporal behavior of the central engine activity and the jet propagation in the massive stellar envelope. Using a pulse search algorithm for bright GRBs, we investigate the time variability of gamma-ray light curves to search a signature of the interaction between the jet and the inner structure of the progenitor. Since this signature might appear in the earlier phase of prompt emission, we divide the light curves into the initial phase and the late phase by referring to the trigger time and the burst duration of each GRB. We also adopt this algorithm for GRBs associated with supernovae/hypernovae that certainly are accompanied by massive stars. However, there is no difference between each pulse interval distribution described by a lognorma distribution in the two phases. We confirm that this result can be explained by the photospheric emission model if the energy injection of the central engine is not steady or completely periodic but episodic and described by the lognormal distribution with a mean of ∼1 s.

Abstract
We report two observations of magnetic waves due to He+ pickup ions observed by the Voyager 2 spacecraft in mid-1989 to demonstrate that such waves occur as far out as ∼30 au from the Sun. The observations are sufficiently far from planets, interplanetary shocks, and other possible sources of energetic particles to make newborn interstellar He+ the only likely explanation for the source of the waves. Additionally, the low-frequency waves that might be expected for a variety of cometary pickup species are not seen. The events studied here were picked from a preliminary list of ∼300 events that were discovered based on polarization signatures in daily spectrograms of the magnetic field between 1977 and 1990. Analysis of those observations is ongoing. We present an analysis of these two observations using the same techniques we have employed for recently reported observations closer to the Sun.

Abstract
We present VLA images and HST/STIS spectra of sources within the center of the brightest cluster galaxy (BCG) in Abell 2261. These observations were obtained to test the hypothesis that its extremely large, flat core reflects the ejection of its supermassive black hole. Spectra of three of the four most luminous “knots” embedded in the core were taken to test whether one may represent stars bound to a displaced massive black hole. The three knots have radial velocity offsets

from the BCG. Knots 2 and 3 show kinematics, colors, and stellar masses consistent with infalling low-mass galaxies or larger stripped cluster members. Large errors in the stellar velocity dispersion of Knot 1, however, mean that we cannot rule out the hypothesis that it hosts a high-mass black hole. A2261-BCG has a compact, relic radio source offset by 6.5 kpc (projected) from the optical core’s center, but no active radio core that would pinpoint the galaxy’s central black hole to a tight 10 GHz flux limit

ago, with an equipartition condition magnetic field of 15 μG. These observations are still consistent with the hypothesis that the nuclear black hole has been ejected from its core, but the critical task of locating the supermassive black hole or demonstrating that A2261-BCG lacks one remains to be done.

We present a study of the average X-ray spectral properties of the sources detected by the NuSTAR extragalactic survey, comprising observations of the Extended Chandra Deep Field South (E-CDFS), Extended Groth Strip (EGS), and the Cosmic Evolution Survey (COSMOS).

Le changement climatique, une « grande peur » collective ?

Published: October 2017

Résumé Ce numéro ne pouvait pas ne pas évoquer la question de la perspective d’un changement du climat. C’est au prisme de l’histoire et de la sociologie qu’elle sera ici traitée. Sans discuter, encore moins prendre parti dans les controverses actuelles dont elle est l’objet, mais en montrant et en donnant les raisons pour lesquelles elle ne parvient pas à prendre place et rang dans l’opinion publique à la manière d’une nouvelle grande peur collective, mais seulement comme une inquiétude, comme l’expression et un cas de figure de l’ éco-anxiété qui nous gagne. Peu ou pas visible, ce changement ne se voit pas (encore ?) : on y pense et on l’oublie, voire on le conteste.
Entre le dire et (ne pas) le faire. Les recruteurs et la fabrique des discriminations selon l’apparence physique

Published: October 2017

En France, la loi du 16 novembre 2001 précise qu’« aucune personne ne peut être écartée d’une procédure de recrutement […] en raison […] de son apparence physique ». Pourtant, quelques travaux ont montré l’existence d’un écart entre les discours et volontés anti-discriminatoires des recruteurs et leurs comportements discriminatoires. C’est en mobilisant la théorie de la neutralisation que cet article tente d’expliquer la persistance de cette incohérence. Obtenus à partir d’entretiens semi-directifs menés avec 42 recruteurs de la distribution d’articles sportifs, les résultats de cette étude renseignent autrement les mécanismes de production des situations discriminatoires selon l’apparence physique.
Computing Optimal Forcing Using Laplace Preconditioning
Authors: Brynjell-Rahkola M. , Tuckerman L. S. , Schlatter P. , Henningson D. S. 
Published: October 2017

AbstractFor problems governed by a non-normal operator, the leading eigenvalue of the operator is of limited interest and a more relevant measure of the stability is obtained by considering the harmonic forcing causing the largest system response. Various methods for determining this so-called optimal forcing exist, but they all suffer from great computational expense and are hence not practical for large-scale problems. In the present paper a new method is presented, which is applicable to problems of arbitrary size. The method does not rely on timestepping, but on the solution of linear systems, in which the inverse Laplacian acts as a preconditioner. By formulating the search for the optimal forcing as an eigenvalue problem based on the resolvent operator, repeated system solves amount to power iterations, in which the dominant eigenvalue is seen to correspond to the energy amplification in a system for a given frequency, and the eigenfunction to the corresponding forcing function. Implementation of the method requires only minor modifications of an existing timestepping code, and is applicable to any partial differential equation containing the Laplacian, such as the Navier-Stokes equations. We discuss the method, first, in the context of the linear Ginzburg-Landau equation and then, the two-dimensional lid-driven cavity flow governed by the Navier-Stokes equations. Most importantly, we demonstrate that for the lid-driven cavity, the optimal forcing can be computed using a factor of up to 500 times fewer operator evaluations than the standard method based on exponential timestepping.

Preventive guardianship: just being there does the trick
The most important mechanism for crime prevention is just the presence of guardians. Some counter arguments against this thesis are discussed and rejected. By manipulating the presence of guardians it is possible to influence the level of prevention. It is argued that a large scale evaluation of such measures is wanted.
La patrimonialisation du pire a-t-elle des vertus véritatives et préventives ?
Authors: Belot Robert 
Published: October 2017

Le classement au patrimoine mondial de l’Humanité du Dôme de Genbaku (Hiroshima), en 1996, s’inscrit dans une tendance à distinguer un patrimoine du pire, comme Auschwitz, au nom de ses vertus supposément véritatives, éducatives et préventives. Pourtant, Barack Obama, premier président américain à se rendre sur les lieux du drame, déplorait le 26 mai 2016 « l’absence de perspective historique » de ce lieu de mémoire qui ne permettait pas une « compréhension » adéquate de la « tragédie d’Hiroshima ». La démarche patrimoniale pourrait-elle avoir pour effet pervers de déshistoriser ce qu’elle est censée mémorialiser, constituant ainsi un patrimoine sans mémoire, voire contre l’histoire ? Une stratégie de l’évitement et de l’innocentement aurait-elle transformé le Dôme en « lieu de dé-mémoire » ? C’est une manière de questionner le rôle de l’UNESCO dans les processus de construction des narrations patrimoniales et d’interroger les rapports complexes qu’entretiennent la mémoire, l’histoire et le patrimoine.
Pourquoi les Roumains ne sont-ils pas devenus un peuple slave ?
Authors: Stamati Iurie 
Published: October 2017

Le XVIIIe siècle marque le début de la construction des nations modernes. C’est à ce moment que les lettrés des quatre coins de l’Europe se sont mis à construire des passés pour ces nations. Les nouveaux panthéons nationaux se remplissent vite d’ancêtres glorieux choisis parmi les tribus de l’Antiquité et du Moyen Âge, mais aussi d’ennemis cruels auxquels ils ont dû faire face. La présente étude examine la place attribuée aux anciennes tribus slaves dans l’histoire de la nation roumaine par les lettrés roumains à partir du XVIIe siècle et jusqu’au début du XXe siècle. Nous exposons comment les enjeux politiques et culturels de la société roumaine, les profils personnels (l’origine, la prédilection pour certains courants de pensée, etc.) de ceux qui ont contribué à la rédaction de l’histoire nationale roumaine, ainsi que la professionnalisation de l’historiographie sous l’égide du paradigme positiviste ont déterminé la façon dont les lettrés roumains ont traité ces tribus.
Le ministère du Patrimoine canadien et la « mosaïque du développement durable »
Authors: Vaillancourt Benoit 
Published: October 2017

Cet article examine la place accordée à la culture dans les stratégies de développement durable du ministère du Patrimoine canadien depuis la fin des années 1990. Il part du constat que de nombreux textes internationaux soulignent l’apport de la culture à un développement durable, mais que sa reconnaissance dépend aussi des politiques particulières des États et des institutions. À cet égard, le cas du ministère du Patrimoine canadien est révélateur des limites de la perspective canadienne, puisqu’après s’être impliqué dans l’étude et la promotion des enjeux sociaux et culturels du développement durable, il s’en est désengagé peu à peu sous le coup de nouvelles directives fédérales. Afin d’éclairer la position du ministère dans cette affaire, l’article commence par retracer son histoire institutionnelle, dissipant ainsi un flou terminologique qui entoure les mots « patrimoine » et « culture » depuis sa création, et plus encore depuis sa séparation d’avec Parcs Canada. Une seconde partie présente cette séparation comme un facteur déterminant dans la réorientation de son approche au développement durable étant donnés les liens forts entre l’environnement d’une part, et les espaces naturels et les lieux historiques sous la responsabilité de Parcs Canada d’autre part. À partir de stratégies triennales et d’autres documents officiels, la dernière partie résume les démarches successives du ministère et fait ressortir la difficulté à rendre opérationnelle l’articulation entre le développement durable et la culture.
Of Chiefs and Kings
Authors: de Stecher Annette 
Published: October 2017

“Of Chiefs and Kings” is about the role of Wendat diplomatic traditions, explored through documentary and pictorial evidence and the arts of ceremonial dress. I will describe diplomatic interactions between Wendat and British communities between 1838 and 1842, through which the Wendat affirmed commitments of military and civilian support and asserted a continued Wendat presence in their traditional territories. By their dynamic public representation of Indigenous identity, they denied the romanticized notion of the vanishing race, deeply rooted in the popular imagination. These events marked a particular moment within a Wendat history of diplomatic engagement and intercultural exchange with European leaders, extending back to the early seventeenth century.Wendat and British first-hand accounts furnish perspectives of individual members of each community, while Wendat elders’ recollections of ceremonial traditions give important community knowledge of the significance of these events to the Wendat, at an important time in the history of Wendake and Lower Canada.
