Impending Transition From Pediatric to Adult Health Services: A Qualitative Study of the Experiences of Adolescents With Eating Disorders and Their Caregivers
Authors: Nadarajah Ajantha , Dimitropoulos Gina , Grant Christina , Webb Cheryl , Couturier Jennifer 
Published: May 2021

Background: There is a dearth of research that identifies pediatric to adult health care transition practices that yield positive outcomes for young people with eating disorders (EDs). Further, adolescent and caregiver perspectives are poorly understood and underrepresented in the literature. The purpose of this study, focused on the impending transition from pediatric to adult health services, was twofold: (a) to identify adolescent and caregiver perspectives of barriers and facilitators of a successful transition for adolescents with EDs; and (b) to understand adolescent and caregiver suggestions of interventions for a successful transition.Design/Method: We recruited five adolescents with EDs who were about to be transferred out of pediatric care as well as their caregivers. We conducted a qualitative study in accordance with the principles of interpretive description. Through conducting semi-structured, in-depth interviews with adolescents and caregivers, we investigated their knowledge about health system transitions and anticipated experiences. We identified participants' perceptions of barriers and facilitators regarding a successful transition, as well as their recommendations to improve the transfer of care.Results: Participants possessed a limited understanding of transition processes despite the fact that they were about to be transferred to adult care. From our analyses, the following themes were identified as barriers during the transition process: re-explaining information to adult healthcare providers, lack of professional support while waiting for uptake into the adult health system, and late timing of transition of care discussions. Both adolescents and caregivers expressed that involvement of parents and the pediatric healthcare team helped to facilitate a successful transfer of care. In addition, participants expressed that the implementation of a Transition Coordinator and Transition Passport would be helpful in facilitating a seamless transfer between systems of care.Discussion: These findings demonstrate a significant gap in the system and highlight the importance of developing interventions that facilitate a successful transition. The themes that emerged from this study can inform the development of interventions to facilitate a coordinated transition from pediatric to adult health services for adolescents with EDs.

Abstract
This letter reports systematic measurements of the anisotropic magneto-Seebeck effect (AMSE) of ferromagnetic Ni100−x
Pt
x
alloys with different Pt concentration ratios x. By simultaneously measuring an applied temperature difference and generated thermopower at the same positions, the Seebeck coefficient under a magnetic field is quantified with high reliability at the temperatures ranging from 300 to 550 K. The AMSE of the alloys is maximized at around x = 5 at% in the high temperature range and disappears at the temperatures lower than the Curie temperature. The systematic dataset and experimental techniques established here will invigorate spin caloritronics studies.

Abstract
Presented are the first interferometric images of cool starspots on the chromospherically active giant λ Andromedae. Using the Michigan Infra-Red Combiner coupled to the Center for High Angular Resolution Astronomy Array, 26 interferometric observations were made between 2008 August 17 and 2011 September 24. The photometric time series acquired at Fairborn Observatory spanning 2008 September 20 to 2011 January 20 is also presented. The angular diameter and power-law limb-darkening coefficient of this star are 2.759 ± 0.050 mas and 0.229 ± 0.111, respectively. Starspot properties are obtained from both modeled and SQUEEZE reconstructed images. The images from 2010 through 2011 show anywhere from one to four starspots. The cadence in the data for the 2010 and 2011 data sets is sufficient to measure a stellar rotation period based on apparent starspot motion. This leads to estimates of the rotation period (P
2010 = 61 ± 4.0 days, P
2011 = 54.0 ± 2.4 days) that are consistent with the photometrically determined period of 54.8 days. In addition, the inclination and position angle of the rotation axis are computed for both the 2010 and 2011 data sets; values (

Skye: A Differentiable Equation of State
Authors: Jermyn Adam S. , Schwab Josiah , Bauer Evan , Timmes F. X. , Potekhin Alexander Y. 
Published: May 2021

Abstract
Stellar evolution and numerical hydrodynamics simulations depend critically on access to fast, accurate, thermodynamically consistent equations of state. We present Skye, a new equation of state for fully ionized matter. Skye includes the effects of positrons, relativity, electron degeneracy, Coulomb interactions, nonlinear mixing effects, and quantum corrections. Skye determines the point of Coulomb crystallization in a self-consistent manner, accounting for mixing and composition effects automatically. A defining feature of this equation of state is that it uses analytic free energy terms and provides thermodynamic quantities using automatic differentiation machinery. Because of this, Skye is easily extended to include new effects by simply writing new terms in the free energy. We also introduce a novel thermodynamic extrapolation scheme for extending analytic fits to the free energy beyond the range of the fitting data while preserving desirable properties like positive entropy and sound speed. We demonstrate Skye in action in the MESA stellar evolution software instrument by computing white dwarf cooling curves.
Probing Uncertainties in Diagnostics of a Synthetic Chromosphere
Authors: Schmit Don , Martinez-Sykora Juan , Pereira Tiago , Asensio Ramos Andrés 
Published: May 2021

Abstract
Effective spectroscopic diagnostics rely on the ability to convert a particular flux measurement into a physical interpretation. Knowledge of uncertainty is a central component of diagnostics. We present data from a simulated solar-like chromosphere, where we have addressed the question of whether degeneracy is a problem in mapping from a non-LTE chromospheric line profile to a particular vertical stratification of atmospheric properties along the line of sight. Our results indicate that stratification degeneracies do exist, at least in our simulated atmosphere. We quantify this effect through the creation of posterior densities for atmospheric properties based on the Mg ii h line profile using the approximate Bayesian computation (ABC) technique. We find that the predictive power of the ABC temperature posterior systematically varies as a function of atmospheric column mass and ground-truth temperature. The ABC posteriors more effectively reproduce the spectral intensity in the Ca ii 8542 Å line than they do temperature stratification, although residual error in the Ca ii line core is common. Our results illustrate that some degeneracies should be alleviated through simultaneous analysis of multiple chromospheric lines.
Stellar Rotation in the K2 Sample: Evidence for Modified Spin-down
Authors: Gordon Tyler A. , Davenport James R. A. , Angus Ruth , Foreman-Mackey Daniel , Agol Eric , Covey Kevin R. , Agüeros Marcel A. , Kipping David 
Published: May 2021

Abstract
We analyze light curves of 284,834 unique K2 targets using a Gaussian process model with a quasi-periodic kernel function. By cross-matching K2 stars to observations from Gaia Data Release 2, we have identified 69,627 likely main-sequence stars. From these we select a subsample of 8977 stars on the main sequence with highly precise rotation period measurements. With this sample we recover the gap in the rotation period−color diagram first reported by McQuillan et al. While the gap was tentatively detected in Reinhold & Hekker, this work represents the first robust detection of the gap in K2 data for field stars. This is significant because K2 observed along many lines of sight at wide angular separation, in contrast to Kepler’s single line of sight. Together with recent results for rotation in open clusters, we interpret this gap as evidence for a departure from the t
−1/2 Skumanich spin-down law, rather than an indication of a bimodal star formation history. We provide maximum likelihood estimates and uncertainties for all parameters of the quasi-periodic light-curve model for each of the 284,834 stars in our sample.
A Supernova-driven, Magnetically Collimated Outflow as the Origin of the Galactic Center Radio Bubbles
Authors: Zhang Mengfei , Li Zhiyuan , Morris Mark R. 
Published: May 2021

Abstract
A pair of nonthermal radio bubbles recently discovered in the inner few hundred parsecs of the Galactic center bears a close spatial association with elongated, thermal X-ray features called the X-ray chimneys. While their morphology, position, and orientation vividly point to an outflow from the Galactic center, the physical processes responsible for the outflow remain to be understood. We use 3D magnetohydrodynamic simulations to test the hypothesis that the radio bubbles/X-ray chimneys are the manifestation of an energetic outflow driven by multiple core-collapsed supernovae (SNe) in the nuclear stellar disk, where numerous massive stars are known to be present. Our simulations are run with different combinations of two main parameters, the supernova birth rate and the strength of a global magnetic field being vertically oriented with respect to the disk. The simulation results show that a hot gas outflow can naturally form and acquire a vertically elongated shape due to collimation by the magnetic pressure. In particular, the simulation with an initial magnetic field strength of 80 μG and a supernova rate of 1 kyr−1 can well reproduce the observed morphology, internal energy, and X-ray luminosity of the bubbles after an evolutionary time of 330 kyr. On the other hand, a magnetic field strength of 200 μG gives rise to an overly elongated outflow that is inconsistent with the observed bubbles. The simulations also reveal that, inside the bubbles, mutual collisions between the shock waves of individual SNe produce dense filaments of locally amplified magnetic field. Such filaments may account for a fraction of the synchrotron-emitting radio filaments known to exist in the Galactic center.
Une administration centrale à la campagne
Authors: Lambert Olivier 
Published: May 2021

Ce cahier apporte un éclairage sur un épisode singulier dans l’histoire de la Compagnie Alais, Froges et Camargue (AFC), qui deviendra Pechiney en 1950, celui de l’exil de son administration centrale à Éguilles, en Pays d’Avignon, pendant la Seconde Guerre mondiale. Pour relater cet événement, il s’appuie sur deux témoignages écrits d’anciens collaborateurs d’AFC qui ont participé à l’aventure d’Éguilles. Le premier a été rédigé en 1954 par Jean Fournier de Lempdes, à l’époque archiviste du groupe, et se trouve dans les archives historiques de Pechiney. Le second a été recueilli en 1998 par l’IHA et figure dans sa collection « Travaux d’auteurs ». Il est de la plume de Bernard Siméon qui était directeur technique auprès de l’adminstration centrale d’AFC lors du repli à Éguilles. Ces deux témoignages sont illustrés par un portfolio d’images qui donnent à voir ce que fut le cadre de vie et le quotidien des femmes et des hommes de l’administration d’AFC au cours des années 1940-1943. L’ensemble de ces photographies provient d’un album de 158 tirages, appartenant à la Collection photographique de L’Aluminium Français gérée par l’IHA.
Charles Rollin (1661-1741) : de l’éducation des princes aux élites du XIX e siècle

Charles Rollin (1661-1741), professeur français de rhétorique, mais aussi homme d’Église, rattaché au mouvement des jansénistes, esquisse un projet éducatif qui vise à transmettre aux princes et aux sujets des idées nouvelles et à insuffler en même temps des principes moraux et religieux de son époque. Le pédagogue qui meurt avant la Révolution tient une correspondance avec le roi de Prusse Frédéric II. Son Histoire ancienne (1730-1738) s’inscrit dans le modèle humaniste qui, au xvii e siècle, fait triompher, dans l’histoire de l’Antiquité, des exempla qui « subordonnent les registres politique et militaire aux catégories morales ». Au fil de son Histoire , nombreux sont les portraits de rois (Philippe de Macédoine), de princes (Alexandre le Grand), ou d’hommes politiques (Solon). À travers leurs actes il fait réagir les lecteurs afin qu’ils formulent un jugement à l’égard des grands hommes et de leur personnalité. Le point fort de cette Histoire élaborée sur le mode narratif, mêlant volontiers les références religieuses, disposant d’un appareil de citations empruntées aux auteurs anciens est qu’elle finit par convaincre les publics lettrés et trouver un écho dans la nouvelle génération de ce début du xix e siècle.

Histoire d’une institution au cœur de la Francophonie
Authors: Gendreau-Massaloux Michèle 
Published: May 2021

L’histoire de l’AUF, institution universitaire et francophone, est marquée à la fois par l’évolution de la Francophonie institutionnelle et par sa dimension proprement universitaire. C’est au début des années 1960 qu’est fondée l’association des universités partiellement ou entièrement de langue française, l’AUPELF, réseau mis en place par quelques universitaires de divers pays soucieux d’échanges et de coopération. Le caractère associatif de cette instance, qui regroupe rapidement une quarantaine d’universités, permet des prises de décision collégiales et garantit une véritable liberté d’action, mais la maintient dans un état de fragilité financière.En 1987, l’AUPELF devient l’AUPELF-UREF, par adjonction d’une « université des réseaux d’expression française », sorte d’université hors les murs, mais sa situation ne s'améliore pas.Deux événements amènent l'institution à se redresser, à se transformer et à se consolider tout en préservant son autonomie. D'une part, en 1997, avec l’établissement des nouvelles structures de la Francophonie politique, l’AUPELF trouve une nouvelle dynamique : elle devient l’AUF, bras armé universitaire de l’AIF (qui deviendra l’OIF). D'autre part, au début des années 2000, la refonte des statuts et une nouvelle impulsion interne, qui étend les possibilités d'adhésion volontaire des institutions d'enseignement supérieur et de recherche et déconcentre la gestion des programmes, assure à l'AUF l’appui des États membres sans que soit amoindrie sa capacité propre de décision et d'action, garanties par les nouveaux statuts. Un nombre important d’universités font leur entrée dans l'ensemble mondial qui se dessine. Des programmes prioritaires de recherche et d’éducation sont définis : langue et culture francophones, démocratie et État de droit, campus numériques francophones et accès à l’information scientifique, environnement durable. L'évolution qui s'engage donne un rôle important aux initiatives des membres actifs, ce qui conforte la mutation encore en cours.
Contre la disparition du monde francophone de l’Alliance israélite universelle : les efforts de Vitalis Danon à Tunis (1945-1958)
Authors: Omer Danielle 
Published: May 2021

Il y a presque 150 ans maintenant, l’Alliance israélite universelle a créé, dans les pays du bassin méditerranéen oriental et méridional, un réseau d’écoles ayant le français comme langue d’enseignement. Que devient ce monde francophone méconnu du grand public au moment où émerge peu à peu la francophonie institutionnalisée ? La création de l’État d’Israël, les processus de la décolonisation bouleversent les données économiques, politiques et identitaires dans cette zone géographique. L’article tente de donner un aperçu du devenir de cette francophonie spécifique en suivant plus particulièrement les efforts de Vitalis Danon, directeur d’école à Tunis après la guerre.
« Guerre aux mots étrangers ! » : le protectionnisme et la censure dans la lexicographie portugaise du XXe siècle
Authors: Carmino Marques Fernando 
Published: May 2021

Au nom de la pureté linguistique, dont l’origine nous renvoie à un passé plus ou moins éloigné, sélectif et paradigmatique, les lexicologues portugais, défenseurs d’une telle opinion n’hésitent pas à associer « pur » à « supérieur ». Ces combattants, dans le cas lusitanien, estiment la langue portugaise supérieure aux autres vu qu’elle possède en elle tous les moyens pour adapter l’expression à l’idée. C’est donc à un combat, sans merci, aux mots étrangers que nous assistons pendant tout le XXe siècle.
The bandit and his myths
Authors: Michelutti Lucia , Picherit David 
Published: May 2021

De Pablo Escobar à Phoolan Devi, les mythes de bandits plus ou moins sociaux se développent de manière exponentielle et se répandent par le biais des médias numériques. Célébrant des bandits, des gangsters, des politiciens mafieux – morts ou vivants – à partir de bricolages transculturels, ces mythes constituent des armes effectives dans le présent immédiat mais aussi un rendez-vous avec une postérité incertaine. Fiction et faits semblent ainsi fusionner et donner naissance à des réalités fictionnelles puissantes qui débordent les vies présentes et post-mortem de ces figures. Cette introduction expose comment ces réalités fictionnelles sont concrètement élaborées par le biais d’« écritures scénarisées de mythes » qui sont pleinement constitutives de l’autorité de ces bandits. Ce concept théorique que nous développons est aussi un objet ethnographique : nous explorons empiriquement cette fabrique quotidienne de la séduction, de la fascination et de l’effroi, laquelle est indissociable de la capacité à faire agir autrui dans les économies politiques criminelles.
