A Unifying Principle for a Researcher Learning Safety: Reduce Uncertainty!
Authors: Kao Camilla , Furr Russell 
Published: March 2018

Conveying safety information to researchers is challenging. A list of rules and best practices often is not remembered thoroughly even by individuals who want to remember everything. Researchers in science thinking according to principles: mathematical, physical, and chemical laws; biological paradigms. They use frameworks and logic, rather than memorization, to achieve the bulk of their work. Can safety be taught to researchers in a manner that matches with how they are trained to think? Is there a principle more defined than "Think safety!" that can help researchers make good decisions in situations that are complex, new, and demanding?Effective trainings in other professions can arise from the use of a mission statement that participants internalize as a mental framework or model for future decision-making. We propose that mission statements incorporating the concept of reducing uncertainty could provide such a framework for learning safety. This essay briefly explains the definition of uncertainty in the context of health and safety, discusses the need for an individual to personalize a mission statement in order to internalize it, and connects the idea of greater control over a situation with less uncertainty with respect to safety. The principle of reducing uncertainty might also help non-researchers think about safety. People from all walks of life should be able to understand that more control over their situations provides more protection for them, their colleagues, and the environment.
José Gabriel Navarro y sus aportes en torno al arte, educación e identidad nacional en el contexto del Segundo Congreso Científico Panamericano de 1915
Authors: Moreno Andrea 
Published: March 2018

Investigaciones sobre la obra de José Gabriel Navarro principalmente han revisado y discutido sus aportes y disertaciones sobre el denominado arte colonial quiteño. En esta ocasión, se busca contribuir al entendimiento de la figura de Navarro como intelectual de la primera mitad del siglo XX y sus acciones en lo artístico educativo y la construcción de un discurso sobre un arte americano en el contexto panamericano. Para lo cual, se toma como documento central, la propuesta de educación artística de Pedro Pablo Traversari, José Gabriel Navarro y José María Durán para el Segundo Congreso Científico Panamericano de 1915. Junto a esto, el recurso epistolar del Fondo José Gabriel Navarro de la Biblioteca Ecuatoriana Aurelio Espinosa Pólit, da cuenta de diálogos a nivel intelectual de la configuración utópica y homogeneizante de un arte vernáculo, a la vez que permite valorar la vinculación entre diferentes actores culturales de inicios del siglo XX.

En este Dossier visual se presenta la serie Los Coros Menores y el artículo el Fuego y los Perros. El artículo lo puede encontrar en la galerada bajo el título 01 PDF y la serie fotográfica: Los Coros Menores, en la galerada 02 PDF.
Numerosas veces me han preguntado cuál es la relación entre el paisaje y los bailarines en Los Coros Menores y siempre la respuesta más elemental resulta la de mayor precisión: ambos son hechos de un mismo mundo. Los personajes provienen de tres lugares: Alto Hospicio, en Chile, y El Alto y Oruro, en Bolivia. En el caso chileno, los retratados son danzantes de la fiesta de La Tirana, celebración relativa a la Virgen del Carmen. En la festividad boliviana, son bailarines del carnaval que, al igual que en el resto del mundo católico, se celebra en todo ese país a fines de febrero.

Detailed Metallographic Analysis of the Surface Layer Structure of Carbonitrided Case-Hardening Steels after Varied Tempering Treatments
Authors: Saddei P. , Meier P. 
Published: March 2018

Abstract
This work aimed at performing a more in-depth analysis of the influence of the tempering temperature on the microstructure development in carbonitrided case-hardening steels. To this end, X-ray measurements are performed alongside various metallographic methods. It was, above all, due to the unusually high tempering temperature of 280 °C for case-hardened samples that the conventional characterization methods initially did not yield satisfying results. Therefore, examinations in the scanning and the transmission electron microscope as well as EBSD investigations were performed alongside the light microscopy analyses. The motivation for the examinations was and is the challenge or rather the desire to gain better understanding of the correlation between load capacity results and the respective surface layer microstructures.
Fretting Fatigue Cracking of a Center Guide Bolt Supporting the Combustion Chamber in a Heavy-duty Gas Turbine Engine
Authors: Neidel A. , Fischer B. , Gädicke T. 
Published: March 2018

Abstract
The slotted center guide bolt of the center guide feature of the lower part of the outer shell of an annular combustion chamber was found fractured in a heavy-duty gas turbine engine used for power generation, after approximately 5.500 operating hours. The incident was a one-off event and not a recurring incident. No similar events were reported from the fleet; hence the failure was not considered a field issue. The metallurgical root cause investigation that was ordered to determine the failure mechanism revealed that the incident center guide bolt failed by fretting fatigue cracking, a high cycle fatigue (HCF) phenomenon.
Gravitational Instability of a Dust Layer Composed of Porous Silicate Dust Aggregates in a Protoplanetary Disk
Authors: Tatsuuma Misako , Michikoshi Shugo , Kokubo Eiichiro 
Published: March 2018

Abstract
Planetesimal formation is one of the most important unsolved problems in planet formation theory. In particular, rocky planetesimal formation is difficult because silicate dust grains are easily broken when they collide. It has recently been proposed that they can grow as porous aggregates when their monomer radius is smaller than ∼10 nm, which can also avoid the radial drift toward the central star. However, the stability of a layer composed of such porous silicate dust aggregates has not been investigated. Therefore, we investigate the gravitational instability (GI) of this dust layer. To evaluate the disk stability, we calculate Toomre’s stability parameter Q, for which we need to evaluate the equilibrium random velocity of dust aggregates. We calculate the equilibrium random velocity considering gravitational scattering and collisions between dust aggregates, drag by mean flow of gas, stirring by gas turbulence, and gravitational scattering by gas density fluctuation due to turbulence. We derive the condition of the GI using the disk mass, dust-to-gas ratio, turbulent strength, orbital radius, and dust monomer radius. We find that, for the minimum mass solar nebula model at 1 au, the dust layer becomes gravitationally unstable when the turbulent strength α ≲ 10−5. If the dust-to-gas ratio is increased twice, the GI occurs for α ≲ 10−4. We also find that the dust layer is more unstable in disks with larger mass, higher dust-to-gas ratio, and weaker turbulent strength, at larger orbital radius, and with a larger monomer radius.
Resolved Millimeter Observations of the HR 8799 Debris Disk
Authors: Wilner David J. , MacGregor Meredith A. , Andrews Sean M. , Hughes A. Meredith , Matthews Brenda , Su Kate 
Published: March 2018

Abstract
We present 1.3 mm observations of the debris disk surrounding the HR 8799 multi-planet system from the Submillimeter Array to complement archival ALMA observations that spatially filtered away the bulk of the emission. The image morphology at 3.″8 (150 au) resolution indicates an optically thin circumstellar belt, which we associate with a population of dust-producing planetesimals within the debris disk. The interferometric visibilities are fit well by an axisymmetric radial power-law model characterized by a broad width, ΔR/R ≳ 1. The belt inclination and orientation parameters are consistent with the planet orbital parameters within the mutual uncertainties. The models constrain the radial location of the inner edge of the belt to

au. In a simple scenario where the chaotic zone of the outermost planet b truncates the planetesimal distribution, this inner edge location translates into a constraint on the planet b mass of

M
Jup. This mass estimate is consistent with infrared observations of the planet luminosity and standard hot-start evolutionary models, with the uncertainties allowing for a range of initial conditions. We also present new 9 mm observations of the debris disk from the Very Large Array and determine a millimeter spectral index of 2.41 ± 0.17. This value is typical of debris disks and indicates a power-law index of the grain size distribution q = 3.27 ± 0.10, close to predictions for a classical collisional cascade.
On the Occurrence of Thermal Nonequilibrium in Coronal Loops

Published: March 2018

Abstract
Long-period EUV pulsations, recently discovered to be common in active regions, are understood to be the coronal manifestation of thermal nonequilibrium (TNE). The active regions previously studied with EIT/Solar and Heliospheric Observatory and AIA/SDO indicated that long-period intensity pulsations are localized in only one or two loop bundles. The basic idea of this study is to understand why. For this purpose, we tested the response of different loop systems, using different magnetic configurations, to different stratifications and strengths of the heating. We present an extensive parameter-space study using 1D hydrodynamic simulations (1020 in total) and conclude that the occurrence of TNE requires specific combinations of parameters. Our study shows that the TNE cycles are confined to specific ranges in parameter space. This naturally explains why only some loops undergo constant periodic pulsations over several days: since the loop geometry and the heating properties generally vary from one loop to another in an active region, only the ones in which these parameters are compatible exhibit TNE cycles. Furthermore, these parameters (heating and geometry) are likely to vary significantly over the duration of a cycle, which potentially limits the possibilities of periodic behavior. This study also confirms that long-period intensity pulsations and coronal rain are two aspects of the same phenomenon: both phenomena can occur for similar heating conditions and can appear simultaneously in the simulations.
Implosive Collapse about Magnetic Null Points: A Quantitative Comparison between 2D and 3D Nulls
Authors: Thurgood Jonathan O. , Pontin David I. , McLaughlin James A. 
Published: March 2018

Abstract
Null collapse is an implosive process whereby MHD waves focus their energy in the vicinity of a null point, forming a current sheet and initiating magnetic reconnection. We consider, for the first time, the case of collapsing 3D magnetic null points in nonlinear, resistive MHD using numerical simulation, exploring key physical aspects of the system as well as performing a detailed parameter study. We find that within a particular plane containing the 3D null, the plasma and current density enhancements resulting from the collapse are quantitatively and qualitatively as per the 2D case in both the linear and nonlinear collapse regimes. However, the scaling with resistivity of the 3D reconnection rate—which is a global quantity—is found to be less favorable when the magnetic null point is more rotationally symmetric, due to the action of increased magnetic back-pressure. Furthermore, we find that, with increasing ambient plasma pressure, the collapse can be throttled, as is the case for 2D nulls. We discuss this pressure-limiting in the context of fast reconnection in the solar atmosphere and suggest mechanisms by which it may be overcome. We also discuss the implications of the results in the context of null collapse as a trigger mechanism of Oscillatory Reconnection, a time-dependent reconnection mechanism, and also within the wider subject of wave–null point interactions. We conclude that, in general, increasingly rotationally asymmetric nulls will be more favorable in terms of magnetic energy release via null collapse than their more symmetric counterparts.
How Black Holes Shape Globular Clusters: Modeling NGC 3201
Authors: Kremer Kyle , Ye Claire S. , Chatterjee Sourav , Rodriguez Carl L. , Rasio Frederic A. 
Published: March 2018

Abstract
Numerical simulations have shown that black holes (BHs) can strongly influence the evolution and present-day observational properties of globular clusters (GCs). Using a Monte Carlo code, we construct GC models that match the Milky Way cluster NGC 3201, the first cluster in which a stellar-mass BH was identified through radial velocity measurements. We predict that NGC 3201 contains ≳200 stellar-mass BHs. Furthermore, we explore the dynamical formation of main-sequence–BH binaries and demonstrate that systems similar to the observed BH binary in NGC 3201 are produced naturally. Additionally, our models predict the existence of bright blue straggler–BH binaries that are unique to core-collapsed clusters, which otherwise retain few BHs.
Penser l’intrapreneuriat social à l’aune du contrat psychologique : un défi de la RSE ?
Authors: Gatignon-Turnau Anne-Laure , Puech Lucie , Fabre Catherine 
Published: March 2018

Cet article vise à éclairer la relation d’emploi de l’intrapreneur social, figure centrale de la mise en œuvre des dispositifs RSE de type ascendant ou « bottom up ». Dans le cadre de ces pratiques, l’organisation encourage en effet ses salariés à porter des initiatives citoyennes en son nom. Afin de mieux comprendre la relation entre l’intrapreneur social et son organisation, nous adoptons une démarche méthodologique exploratoire, qualitative et assise sur un codage théorique issu de la théorie du contrat psychologique développée par Rousseau (1995). Nous l’appliquons au cas d’une mutuelle d’assurance française qui a explicitement fait le choix de lancer un projet citoyen reposant sur l’intrapreneuriat social. Ce projet, que nous avons suivi pendant deux ans, nous permet d’analyser la dynamique relationnelle qui se noue entre l’organisation et les collaborateurs, devenus des « intrapreneurs sociaux ». Nous montrons que le contrat psychologique de l’intrapreneur étend celui du salarié à de nouvelles obligations réciproques sociales et organisationnelles, auxquelles les salariés donnent principalement une signification idéologique. De plus, lorsque ces nouvelles obligations ne sont pas respectées, le contrat psychologique apparait fragilisé, ce qui remet en cause la pérennité de l’engagement des intrapreneurs sociaux dans l’organisation. Ces résultats nous permettent d’enrichir la littérature sur la GRH des intrapreneurs, et de formuler des recommandations à destination des managers en charge de la mise en œuvre de démarches de RSE ascendantes.
Les débats contemporains sur « la fin des États »
Authors: Ramel Frédéric 
Published: March 2018

La thématique de « la fin des États » a suscité de vigoureux débats dans les cercles universitaires dans les années 1970 et à la fin de la guerre froide. Ils ont connu de nouveaux développements après le 11 septembre 2001, la crise économique de 2008, le Brexit et la victoire de Donald Trump. Si l’on examine ces débats à travers un triple prisme – stratégique, économique et morphologique –, on s’aperçoit que l’opposition entre disparition et résistance des États est largement stérile.
L’Égypte du général Sissi, entre réaction et aspirations révolutionnaires
Authors: Berger Chloé 
Published: March 2018

L’élection présidentielle égyptienne du printemps 2018 aboutira selon toute vraisemblance au maintien au pouvoir d’Abdel Fattah Al-Sissi, l’opposition étant contrôlée de près. Pourtant, le bilan du chef de l’État est loin d’être bon. La situation sécuritaire de l’Égypte s’est dégradée, la pauvreté progresse et les libertés individuelles reculent. Les espoirs suscités par la révolution du 25 janvier 2011 ont cédé la place à de l’amertume, de la frustration et de la colère.
Écosse : nationalisme, immigration et retour des frontières
Authors: Jeannier Fabien 
Published: March 2018

Le débat sur l’indépendance de l’Écosse s’est installé comme une problématique majeure dans le paysage politique britannique depuis une cinquantaine d’années. Le Brexit a relancé une question qui semblait réglée depuis l’échec du référendum du 18 septembre 2014. L’Écosse semble hésiter entre davantage d’autonomie et l’indépendance, hésitation alimentée par les incertitudes sur les négociations entre le Royaume-Uni et l’Union européenne, où les questions d’immigration figurent en bonne place.
La crise en Catalogne, une fracture décisive
Authors: Pellistrandi Benoît 
Published: March 2018

Le 1 er octobre 2017, un référendum d’indépendance – déclaré illégal par le Tribunal constitutionnel espagnol – s’est tenu en Catalogne. 90 % des votants ont choisi l’indépendance. Après la proclamation de la « République de Catalogne », le chef du gouvernement espagnol a dissous le Parlement régional et convoqué des élections anticipées. Si les indépendantistes ont remporté ce scrutin, aucun camp ne sort vainqueur de la crise catalane. L’Espagne a désormais besoin d’une thérapie profonde.
