Toward Evaluating Art Museum Education at the Art Gallery of Ontario
Authors: Chalas Agnieszka 
Published: October 2017

Abstract: Over the past three decades, the museum education field has seen a rise in the frequency of program evaluation. In this paper, I convey little known information about program evaluation at the Art Gallery of Ontario by presenting my findings from an interview I conducted with Judy Koke, the gallery’s Chief of Public Programming and Learning. Our discussion highlights both the barriers the AGO has faced on their journey toward evaluating programmatic value and the strategies the gallery has employed in an effort to enhance its internal evaluation efforts. A brief overview of program evaluation in museums provides the background to this discussion. KEYWORDS: Art museum education; Program evaluationRésumé: Le domaine de la pédagogie muséale a connu au cours des trois dernières décennies un essor quant au nombre d’évaluations de programmes. Je transmets ici le peu de renseignements connus sur l’évaluation des programmes au Musée des beaux-arts de l’Ontario (AGO), au terme d’une entrevue que j’ai menée avec Judy Koke, directrice de l’apprentissage et de la programmation à l’intention du public au Musée. Notre discussion met en évidence tant les obstacles rencontrés par l’AGO dans le cadre de l’évaluation de la valeur des programmes que les stratégies utilisées par le musée pour rehausser ses activités internes d’évaluation. Un bref aperçu de l’évaluation des programmes dans les musées met notre discussion en contexte.MOTS CLES: Éducation musée d'art; évaluation du programme.

Published: October 2017

Abstract: In 2014-2015, the Montreal Museum of Fine Arts (MMFA) and Concordia University's School of Extended Learning conducted a joint pilot project with the objective of determining the effectiveness of a new approach for training volunteer museum guides based on a dialogic method. In this paper, we address: (i) the conceptualization of alternative training based on dialogic concepts; (ii) the development of a new course outline; (iii) the trial period during which volunteers took part in test training; (iv) and, finally, aspects of what we learned during this undertaking. This pilot project is important because it will influence future docent training at the MMFA and possibly elsewhere.KEYWORDS: Museum education; docent training; dialogic teaching; video elicitation; participant-centered exchangesRésumé: Le Musée des beaux-arts de Montréal (MBAM) et l’École d’apprentissage prolongé de l’Université Concordia ont mené en 2014-2015 un projet pilote concerté afin de déterminer l’efficacité d’une nouvelle approche de formation des guides bénévoles au musée, approche fondée sur une méthode dialogique. L’article couvre les points suivants : (i) la conceptualisation d’une nouvelle formation fondée sur les concepts dialogiques ; (ii) la mise au point d’un nouveau schéma de cours ; (iii) la période d’essai pendant laquelle les bénévoles ont suivi la nouvelle formation à l’étude ; et finalement (iv) les différents aspects de ce que nous avons appris au cours de cette démarche. Ce projet pilote est important car il influencera la formation future des guides-interprètes du MBAM et peut-être même ailleurs.MOTS CLES: Éducation muséale; formation guide bénévole; enseignment dialogique; incitation par video; les échanges participant
Against a “Life Hack” Approach to Art Education
Authors: Ruitenberg Claudia W. 
Published: October 2017

Abstract: This paper critiques de Botton and Armstrong’s Art as Therapy project (2013-2015), a collaboration with art museums in Canada, the Netherlands, and Australia, in which labels in the gallery, as well a catalogue and website, explain how viewers might use works of art to serve therapeutic purposes in their lives. The paper argues that, instead of making art more accessible to those who, allegedly, do not find access to art on their own, the Art as Therapy project undermines the force and richness of art by first declaring it useless and inaccessible and then repurposing it as therapeutic life hack.KEYWORDS: Museum education; aesthetic experience; pedagogical intervention; interpretive freedom.Résumé: Cet article se veut une critique du projet Art as Therapy (2013-2015) de Botton et Armstrong, mené en collaboration avec des musées des beaux-arts canadiens, néerlandais et australiens, dans le cadre duquel les affichettes des musées, ainsi que catalogues et sites Web, expliquent aux visiteurs comment utiliser les œuvres d’art à des fins thérapeutiques dans leur quotidien. Dans cet article, je prétends que, plutôt que rendre l’art davantage accessible à ceux qui ne peuvent supposément y accéder de leur propre chef, le projet Art as Therapy sape la force et la richesse de l’art en le déclarant à prime abord inutile et inaccessible pour le transformer par la suite en « astuces de vie » thérapeutiquesMOTS CLES: Éducation muséale; d’expérience esthétique; intervention pédagogique; la liberté interprétative
Reflejos en el paisaje: Museo del Louvre en Lens | Reflecting landscape: Louvre Museum at Lens
Authors: Marco Llombart Jesús 
Published: October 2017

En la parcela de una antigua mina de carbón, reconvertida en un sugerente parque de arqueología minera por la paisajista francesa Catherine Mosbach, el nuevo Museo del Louvre abrió sus puertas en Lens el 4 de diciembre de 2012. Además de revitalizar la actividad local en un área deprimida por la crisis económica en el Norte de Francia, el proyecto museográfico sacaba a la luz más de 600 obras de los almacenes centrales del Louvre en París. El nuevo espacio expositivo de 28.000 m2 y 360 m de longitud se desarrolla en una serie de pabellones de una única planta sobre rasante interconectados por sus esquinas emulando al modelo clásico parisino. Proyectado por SANAA en colaboración con Imrey Culbert, el edificio eleva una declaración arquitectónica del discurso museístico contemporáneo. Los pabellones, más allá de aspirar a convertirse en iconos formalistas del nuevo milenio, suponen una reformulación de la naturaleza física de la arquitectura, que hace de la evanescencia el nuevo argumento estético del momento. El conjunto se integra en el paisaje por su inmaterialidad, celebrando a través del concepto de ‘inexistencia’ la relación del objeto con el entorno. Palabras clave: Evanescencia, reflejo, Louvre Lens, SANAA. Standing on the grounds of an abandoned pithead transformed into an evocative archeological mining park, landscaped by Catherine Mosbach, the new Louvre Museum opened the gates on december 4th of 2012. In addition to the economic boost of the local area, the new museum project released over 600 masterpieces from the basements of Louvre Museum in Paris. The exhibition program covers up to 28.000 m2 with 360 m in legth, rising one floor above ground the museum is structured through a series of pavilions interconnected on their coners as in the classical parisian model. Designed by SANAA and Imrey Culbert, the building becomes an architectural revelation of the contemporary museum discourse. The pavilions, far beyond becoming formal icons of the new millenium, reformulate the physical essence of architecture melting themselves into an evanescent reflection. The architecture becomes integrated into the landscape by its inmateriality, celebrating through its nonexistence the relatioship with the context.

Abstract
Manufacturing tailored materials is commonly faced with the challenge of shrinkage mismatch between layers resulting in delamination. The effects of sintering temperature and carbon variation on the densification and interfacial bond strength of bilayer cemented tungsten carbide and steel processed through powder metallurgy are analyzed. It is revealed through field-emission scanning electron microscopy images that inter-layer diffusion induced by liquid-phase sintering plays a major role in the densification and bonding of layers. Through dimensional analysis of sintered bilayer specimens, the strain rate of cemented tungsten carbide is observed to surpass that of steel. An enhanced densification rate of 6.1 % and M
6C (eta carbide) reduction with increased carbon level results in strong interfacial bonding in specimens sintered at 1 280 °C. At 1 295 °C, diffusion accelerates and the axial and radial shrinkage increase by 14.05 % and 13.35 %, respectively, in 93.8 wt.% WC – 6 wt.% Fe – 0.2 wt.% C and 93.2 wt.% Fe – 6 wt.% WC – 0.8 wt.% C, thereby increasing the tendency for complete delamination.
Experimental evaluation of forming limit diagram and mechanical properties of nano/ultra-fine grained aluminum strips fabricated by accumulative roll bonding
Authors: Rahmatabadi Davood , Hashemi Ramin 
Published: October 2017

Abstract
In this research, for the first time, forming limit diagrams (FLDs) of ultra-fine grained Al/Al samples produced by accumulative roll bonding (ARB) process were evaluated. The samples were successfully prepared through ARB up to the 7th pass. Mechanical properties, tensile fracture surfaces, and crystallite size of samples were investigated. The level of the FLD and elongation at first decreased and then increased, continuously. The results of tensile testing revealed that by increasing the number of ARB passes, the tensile strength increased continuously. Microhardness of Al strips increased and reached a value of 51 VHN after the seventh pass. Results of X-ray diffraction demonstrated that crystallite size decreased from 1 341 nm for annealed condition and it reached to 175 nm for ARBed samples after the 7th pass. SEM images showed that the fracture mode in the ARBed samples was a shear ductile fracture with elongated sophomoric shear dimples.

Abstract
An interlaboratory study was performed to determine the heat capacity of an active material for lithium-ion batteries with layered structure and nominal composition LiNi1/3 · Mn1/3Co1/3O2 (NMC111). The commercial sample, which was characterized using powder X-ray diffraction and inductively coupled plasma–optical emission spectroscopy, is single phase (α-NaFeO2 crystal structure) with a composition of Li1.02Ni0.32Mn0.31Co0.30O2. Heat capacity measurements of the homogeneous sample were performed at five laboratories using different operators, methods, devices, temperature ranges, gas atmospheres and crucible materials. The experimental procedures from each laboratory are presented and the results of the individual laboratories are analyzed. Based on a comprehensive evaluation of the data from each laboratory, the heat capacity of the NMC111 sample from 315 K to 1 020 K is obtained with an expanded reproducibility uncertainty of less than 1.22 %.
The Rotation and Other Properties of Comet 49P/Arend–Rigaux, 1984–2012
Authors: Eisner Nora , Knight Matthew M. , Schleicher David G. 
Published: October 2017

Abstract
We analyzed images of comet 49P/Arend–Rigaux on 33 nights between 2012 January and May and obtained R-band lightcurves of the nucleus. Through usual phasing of the data, we found a double-peaked lightcurve having a synodic rotation period of 13.450 ± 0.005 hr. Similarly, phase dispersion minimization and the Lomb–Scargle method both revealed rotation periods of 13.452 hr. Throughout the 2011/2012 apparition, the rotation period was found to increase by a small amount, consistent with a retrograde rotation of the nucleus. We also reanalyzed the publicly available data from the 1984/1985 apparition by applying the same techniques, finding a rotation period of 13.45 ± 0.01 hr. Based on these findings, we show that the change in rotation period is less than 14 s per apparition. Furthermore, the amplitudes of the lightcurves from the two apparitions are comparable, to within reasonable errors, even though the viewing geometries differ, implying that we are seeing the comet at a similar sub-Earth latitude. We detected the presence of a short-term jet-like feature in 2012 March, which appears to have been created by a short-duration burst of activity on March 15. Production rates obtained in 2004/2005, along with reanalysis of the previous results from 1984/1985, imply a strong seasonal effect and a very steep fall-off after perihelion. This, in turn, implies that a single source region, rather than leakage from the entire nucleus, dominates activity.

Abstract
The Galactic object MWC 137 has been suggested to belong to the group of B[e] supergiants. However, with its large-scale optical bipolar ring nebula and high-velocity jet and knots, it is a rather atypical representative of this class. We performed multiwavelength observations spreading from the optical to the radio regimes. Based on optical imaging and long-slit spectroscopic data, we found that the northern parts of the large-scale nebula are predominantly blueshifted, while the southern regions appear mostly redshifted. We developed a geometrical model consisting of two double cones. Although various observational features can be approximated with such a scenario, the observed velocity pattern is more complex. Using near-infrared integral-field unit spectroscopy, we studied the hot molecular gas in the vicinity of the star. The emission from the hot CO gas arises in a small-scale disk revolving around the star on Keplerian orbits. Although the disk itself cannot be spatially resolved, its emission is reflected by the dust arranged in arc-like structures and the clumps surrounding MWC 137 on small scales. In the radio regime, we mapped the cold molecular gas in the outskirts of the optical nebula. We found that large amounts of cool molecular gas and warm dust embrace the optical nebula in the east, south, and west. No cold gas or dust was detected in the north and northwestern regions. Despite the new insights into the nebula kinematics gained from our studies, the real formation scenario of the large-scale nebula remains an open issue.

Abstract
We report the discovery of KELT-20b, a hot Jupiter transiting a

early A star, HD 185603, with an orbital period of

days. Archival and follow-up photometry, Gaia parallax, radial velocities, Doppler tomography, and AO imaging were used to confirm the planetary nature of KELT-20b and characterize the system. From global modeling we infer that KELT-20 is a rapidly rotating (

) A2V star with an effective temperature of

K, mass of

, radius of

, surface gravity of

, and age of

. The planetary companion has a radius of

, a semimajor axis of

au, and a linear ephemeris of

. We place a

upper limit of

on the mass of the planet. Doppler tomographic measurements indicate that the planetary orbit normal is well aligned with the projected spin axis of the star (

). The inclination of the star is constrained to

, implying a three-dimensional spin–orbit alignment of

. KELT-20b receives an insolation flux of

, implying an equilibrium temperature of of ∼2250 K, assuming zero albedo and complete heat redistribution. Due to the high stellar

, KELT-20b also receives an ultraviolet (wavelength

nm) insolation flux of

, possibly indicating significant atmospheric ablation. Together with WASP-33, Kepler-13 A, HAT-P-57, KELT-17, and KELT-9, KELT-20 is the sixth A star host of a transiting giant planet, and the third-brightest host (in V) of a transiting planet.
Species conservation profiles of endemic spiders (Araneae) from Madeira and Selvagens archipelagos, Portugal
Authors: Cardoso Pedro , Crespo Luís , Silva Isamberto , Borges Paulo , Boieiro Mário 
Published: October 2017

The North Atlantic archipelagos of Madeira and Selvagens present a unique biological diversity including, presently, 56 endemic spider species. Several recent projects provide valuable information on their distribution across most islands and habitats. To date, the only endemic spider assessed according to the IUCN Red List criteria is Hogna ingens. The objective of this paper is to assess all remaining endemic species and advise on possible future conservation actions critical for the survival of endangered species.
Seven species were found to have a continuing decline in either range or population size. Their decline can be mostly attributed to habitat destruction or degradation, invasive plant species that reduce quality of habitat, forest fires at high mountain regions and possible competition for resources from invasive congeners. The tetragnathid M. barreti is considered as possibly extinct due to the suspected impact of a competing species. Although most endemic spiders from the Madeira and Selvagens archipelagos have relatively low extinction risk due to the good condition and protection of the laurisilva forests where many live, there are a number of species requiring urgent attention and protection measures. These include all cave and mountain-restricted species as well as those threatened by competing congeners or invasive plants. Extending current protected areas, restoring original habitats of threatened species and the control of invasive taxa should remain a priority for species survival.

Une recherche sur les facteurs de risque spécifiques des troubles du langage chez les enfants de migrants nés en terre d’accueil, nous a mené à la mise en évidence d’une constellation de déterminants de vulnérabilité interagissant entre eux, susceptibles de créer des situations de traumatismes cumulatifs. La situation de naître « sans-papiers » est alors apparue comme ayant un impact notable dans le développement d’un trouble du langage chez nos sujets. Ces observations nous ont permis de réfléchir aux enjeux et conséquences relatifs à la situation de ces mères migrantes qui mettent au monde des enfants en terre « étrangère », et aux spécificités liées à l’acquisition du langage chez ces enfants. Notre travail révèle un enjeu de santé publique, ainsi que la nécessité de la mise en place d’actions préventives qui permettront d’offrir un cadre extérieur structurant à ces familles migrantes, et participeront à étayer le développement de leurs enfants, afin de prévenir ou de dépister au plus tôt les troubles susceptibles de se développer.
Laisser partir ou retenir les morts ?
Authors: Perichon Laura , Despret Vinciane , Duret Isabelle 
Published: October 2017

Dans le monde moderne, bien que la pensée officielle considère que les morts n’ont d’autre existence que le néant, de nombreuses personnes entretiennent des relations avec leurs proches décédés en se laissant affecter par eux ou encore en posant des actes concrets qui leur sont destinés. A partir d’une définition du deuil comme étant la somme des actes posés par les vivants pour transformer le mort et la relation avec lui (Molinié 2006), nous observons sous l’angle de la transformation de la relation les témoignages de personnes, de chez nous et d’ailleurs, interagissant avec leurs proches décédés. Une question qui préoccupe régulièrement les personnes rencontrées est celle de « laisser partir » le mort ou de le « retenir ». Ces deux dynamiques relationnelles se traduisent par des actes et vécus spécifiques et mènent à des transformations et statuts différents des morts comme des vivants.

Incapables d’accueillir dignement les personnes en quête de protection internationale, les États membres de l’Union européenne rejettent leurs responsabilités sur des pays toujours plus lointains, sommés de bloquer les candidats à la migration à leurs frontières. Cette politique d’externalisation du contrôle des frontières extérieures de l’UE ne cesse de se déployer à coup de millions d’euros dont les sous-traitants les plus méritants sont les premiers bénéficiaires. Mais à quel prix ?
L’intestin de la grande ville

Published: October 2017

Des vapeurs empestées s’abattent sur Londres en 1858 et sur Paris en 1880 à la faveur de deux vagues de chaleur. Ces odeurs insupportables sont-elles dangereuses pour la santé ? Londres avait dû se rendre à l’avis de John Snow sur l’origine hydrique du choléra et rejeter la vieille idée des miasmes, et surtout revenir sur la stratégie folle consistant à déverser directement les excréments humains dans la Tamise afin de détruire les fosses d’aisance. La Grande Puanteur oblige les autorités londoniennes à mettre en chantier des égouts modernes coupant tout aller-retour entre la vidange et l’alimentation en eau potable de la ville. Paris suit le même chemin avec trente ans de retard. On retrace ici cette « crise au ralenti » que fut la bataille du tout-à-l’égout. Étendue sur plus de dix ans, la discussion orageuse n’a pas opposé partisans du miasmatisme et chevau-légers de la bactériologie, mais bien les caciques de la santé publique (miasmes et pastorisme mêlés) aux ingénieurs de la ville, émules des ingénieurs londoniens.
La folie, la sagesse et le cerveau. La postmodernité comme opportunité et comme avertissement
Authors: Sharkey Ronan 
Published: October 2017

L’ambiguïté du terme de « postmoderne », à la fois description effrayée d’un état de société et manifeste en faveur de l’abandon des concepts de raison, de vérité et même de réalité, s’enracine dans l’incommensurabilité contemporaine de nos modes de pensée : tantôt nous croyons devoir nous soumettre à un rationalisme implacable et destructeur, tantôt nous nous réfugions dans un subjectivisme imperméable à toute raison et objectivité. Des recherches récentes et innovatrices qui situent l’étude du cerveau dans le contexte culturel de la modernité tardive font apparaître (à côté de la validité, limitée mais indispensable, de la rationalité instrumentale) le caractère profondément raisonné de l’intuition et de l’affect et par conséquent la complémentarité de nos capacités réflexives pour la résolution des défis auxquels nous sommes confrontés.
