Reflecting From the Margins of Education Faculties: Refiguring the Humanist, and Finding a Space for Story in History
Authors: Christou Theodore Michael 
Published: August 2017

Notwithstanding their traditional characterization as a foundations subject, history of education courses are marginal in pre-service teacher education. This marginalization is framed here in light of a broader concern for the discipline’s turn away from the humanities. History of education’s fundamental purpose, it is argued, lies in the exploration of what it means to be human, and how education has historically been shaped by our values, authority, contexts, and norms. Using stories drawn from literature and memoirs in the teaching of educational history is one means of exploring intersections of education with human cultures and societies across historical contexts. History is etymologically linked with story telling, and both history and literature share narrative features; the two should not be conflated, however, due to distinctive disciplinary features of history, such as the requirement that any claims to truth require what John Dewey referred to as warranted assertability.Keywords: history of education, teacher education,educational foundations, humanities, literature, historical mindedness, John Dewey.
Toward Epistemic Justice: A Critically Reflexive Examination of ‘Sanism’ and Implications for Knowledge Generation
Authors: LeBlanc Stephanie , Kinsella Elizabeth Anne 
Published: August 2017

The dominance of medicalized “psy” discourses in the West has marginalized alternative perspectives and analyses of madness, resulting in the under-inclusion (or exclusion) from mainstream discourse of the firsthand experiences and perspectives of those who identify as Mad. We argue that this marginalization of firsthand knowledge(s) demands closer critical scrutiny, particularly through the use of critical reflexivity. This paper draws on Fricker’s concept of epistemic injustice, whereby a person is wronged in his or her capacity as a knower, as a useful framework for interrogating the subjugation of Mad knowledge(s). Also examined is the problem of sanism, a deeply embedded system of discrimination and oppression, as an underlying component of epistemic injustice. Sanism assumes a pathological view of madness, which can be attributed to what Rimke has termed psychocentrism: the notion that pathologies are rooted in the mind and/or body of the individual, rather than the product of social structures, relations, and problems. The paper examines how sanism marginalizes the knowledge(s) of Mad persons and contributes to epistemic injustice, and considers possibilities for advancing social justice using Mad epistemological perspectives
Plurilinguisme du roman chinois francophone et approche de la diversité et de la pluralité en FLE
Authors: Bouvier-Laffitte Béatrice 
Published: August 2017

Actuellement, neuf auteurs chinois écrivent une œuvre romanesque en français. Ils font agir les langues de leur répertoire (au moins deux langues, en l’occurrence le chinois et le français) pour produire une écriture plurilingue, pluriculturelle. Nous observerons de quelle manière ces écrivains exercent leur compétence plurilingue dans un corpus composé d’extraits de romans. Les différentes formes de plurilinguisme textuel de ces textes sont envisagées comme des ressources au service d’une éducation à la diversité culturelle et à la pluralité linguistique.

French-Chinese novel’s plurilingualism and diversity and plurality approach in FFL
Nine Chinese authors are currently writing novels in French. They use their language resources (Chinese and French at least) to produce plurilingual and multicultural texts. We will study how these writers use their plurilingual competence through different novel excerpts. These various forms of plurilingualism are considered as educational resources to learn about cultural diversity and linguistic plurality.
Enseigner le FLE avec deux œuvres portant deux regards sur la francophonie: le film Chocolat de Claire Denis et le roman Allah n’est pas obligé d’Ahmadou Kourouma
Authors: Barbier Clotilde 
Published: August 2017

Dans cet article, nous présentons l’utilisation de deux œuvres artistiques en classe de FLE qui nous ont permis de traiter de certaines formes de réalités interculturelles et d’altérité inhérentes à la Francophonie : une œuvre littéraire africaine d’expression française, Allah n’est pas obligé de l’écrivain ivoirien Ahmadou Kourouma, et une œuvre cinématographique, Chocolat de la cinéaste française Claire Denis. Nous proposons une démarche pédagogique de découverte et d’analyse du phénomène linguistique et culturel de la francophonie africaine au travers de ces deux œuvres afin de comprendre en partie son origine et aussi de savoir qui est l’Autre, dans son histoire, dans sa culture, dans sa langue (dans ses langues en ce qui concerne Kourouma). L’incursion dans le domaine de l’expression artistique visuelle par le cinéma et écrite par la littérature, donne à l’apprentissage de la langue une dimension sensorielle et émotionnelle complémentaire à l’aspect purement linguistique et culturel et apporte la touche humaniste nécessaire à toute pratique d’enseignement-apprentissage qui engage la construction de soi et les relations à autrui.

Teaching French as a Foreign Language (FFL) with two artistic genres, two ways of looking at French-speaking countries. The colonizer and the colonized: Chocolat by Claire Denis and Allah n’est pas obligé by Ahmadou Kourouma
In this paper, we will present the use of two works of art in a FFL class that will allow us to deal with intercultural realities and otherness inherent to French-speaking countries: an African literary work written in French, Allah n’est pas obligé by the Ivorian writer Ahmadou Kourouma, and a cinematographic work, Chocolat by the French movie-director Claire Denis.
Through these two works, we will propose a pedagogical approach to discover and analyze the linguistic and cultural phenomena that African French-speaking countries represent nowadays in our teaching practice. This analysis will allow us to partly understand its origin and also to know who is the Other, in history, in culture, in language (in his languages as far as Kourouma is concerned).The incursion in the field of visual artistic expression through cinema and artistic written expression through literature gives a sensorial and emotional dimension complementary to the purely linguistic and cultural learning process and the humanistic touch necessary to any teaching / learning practice that involves self-construction and relationships with others.

Onset of a Large Ejective Solar Eruption from a Typical Coronal-jet-base Field Configuration
Authors: Joshi Navin Chandra , Sterling Alphonse C. , Moore Ronald L. , Magara Tetsuya , Moon Yong-Jae 
Published: August 2017

Abstract
Utilizing multiwavelength observations and magnetic field data from the Solar Dynamics Observatory (SDO)/Atmospheric Imaging Assembly (AIA), SDO/Helioseismic and Magnetic Imager (HMI), the Geostationary Operational Environmental Satellite (GOES), and RHESSI, we investigate a large-scale ejective solar eruption of 2014 December 18 from active region NOAA 12241. This event produced a distinctive “three-ribbon” flare, having two parallel ribbons corresponding to the ribbons of a standard two-ribbon flare, and a larger-scale third quasi-circular ribbon offset from the other two. There are two components to this eruptive event. First, a flux rope forms above a strong-field polarity inversion line and erupts and grows as the parallel ribbons turn on, grow, and spread apart from that polarity inversion line; this evolution is consistent with the mechanism of tether-cutting reconnection for eruptions. Second, the eruption of the arcade that has the erupting flux rope in its core undergoes magnetic reconnection at the null point of a fan dome that envelops the erupting arcade, resulting in formation of the quasi-circular ribbon; this is consistent with the breakout reconnection mechanism for eruptions. We find that the parallel ribbons begin well before (∼12 minutes) the onset of the circular ribbon, indicating that tether-cutting reconnection (or a non-ideal MHD instability) initiated this event, rather than breakout reconnection. The overall setup for this large-scale eruption (diameter of the circular ribbon ∼105 km) is analogous to that of coronal jets (base size ∼104 km), many of which, according to recent findings, result from eruptions of small-scale “minifilaments.” Thus these findings confirm that eruptions of sheared-core magnetic arcades seated in fan–spine null-point magnetic topology happen on a wide range of size scales on the Sun.
Magnetically Induced Disk Winds and Transport in the HL Tau Disk
Authors: Hasegawa Yasuhiro , Okuzumi Satoshi , Flock Mario , Turner Neal J. 
Published: August 2017

Abstract
The mechanism of angular momentum transport in protoplanetary disks is fundamental to understanding the distributions of gas and dust in the disks. The unprecedented ALMA observations taken toward HL Tau at high spatial resolution and subsequent radiative transfer modeling reveal that a high degree of dust settling is currently achieved in the outer part of the HL Tau disk. Previous observations, however, suggest a high disk accretion rate onto the central star. This configuration is not necessarily intuitive in the framework of the conventional viscous disk model, since efficient accretion generally requires a high level of turbulence, which can suppress dust settling considerably. We develop a simplified, semi-analytical disk model to examine under what condition these two properties can be realized in a single model. Recent, non-ideal MHD simulations are utilized to realistically model the angular momentum transport both radially via MHD turbulence and vertically via magnetically induced disk winds. We find that the HL Tau disk configuration can be reproduced well when disk winds are properly taken into account. While the resulting disk properties are likely consistent with other observational results, such an ideal situation can be established only if the plasma β at the disk midplane is β
0 ≃ 2 × 104 under the assumption of steady accretion. Equivalently, the vertical magnetic flux at 100 au is about 0.2 mG. More detailed modeling is needed to fully identify the origin of the disk accretion and quantitatively examine plausible mechanisms behind the observed gap structures in the HL Tau disk.
The Molecular Cloud S242: Physical Environment and Star-formation Activities
Authors: Dewangan L. K. , Baug T. , Ojha D. K. , Janardhan P. , Devaraj R. , Luna A. 
Published: August 2017

Abstract
We present a multi-wavelength study to probe the star-formation (SF) processes on a larger scale (

) around the S242 site. The S242 molecular cloud is depicted in a velocity range from −3.25 to 4.55 km s−1 and has a spatially elongated appearance. Based on the virial analysis, the cloud is prone to gravitational collapse. The cloud harbors an elongated filamentary structure (EFS; length ∼25 pc), which is evident in the Herschel column density map, and the EFS has an observed mass per unit length of ∼200

pc−1, exceeding the critical value of ∼16

pc−1 (at T = 10 K). The EFS contains a chain of Herschel clumps (M
clump ∼ 150–1020

), revealing the evidence of fragmentation along its length. The most massive clumps are observed at both the EFS ends, while the S242 H ii region is located at one EFS end. Based on the radio continuum maps at 1.28 and 1.4 GHz, the S242 H ii region is ionized by a B0.5V–B0V type star and has a dynamical age of ∼0.5 Myr. The photometric 1–5 μm data analysis of point-like sources traces young stellar objects (YSOs) toward the EFS and the clusters of YSOs are exclusively found at both the EFS ends, revealing the SF activities. Considering the spatial presence of massive clumps and YSO clusters at both the EFS ends, the observed results are consistent with the prediction of an SF scenario of the end-dominated collapse driven by the higher acceleration of gas.

Abstract
Monitoring of Sagittarius A* from X-ray to radio wavelengths has revealed structured variability—including X-ray flares—but it is challenging to establish correlations between them. Most studies have focused on variability in the X-ray and infrared, where variations are often simultaneous, and because long time series at submillimeter and radio wavelengths are limited. Previous work on submillimeter and radio variability hints at a lag between X-ray flares and their candidate submillimeter or radio counterparts, with the long wavelength data lagging the X-ray. However, there is only one published time lag between an X-ray flare and a possible radio counterpart. Here we report nine contemporaneous X-ray and radio observations of Sgr A*. We detect significant radio variability peaking

minutes after the brightest X-ray flare ever detected from Sgr A*. We also report other potentially associated X-ray and radio variability, with the radio peaks appearing

minutes after these weaker X-ray flares. Taken at face value, these results suggest that stronger X-ray flares lead to longer time lags in the radio. However, we also test the possibility that the variability at X-ray and radio wavelengths is not temporally correlated. We cross-correlate data from mismatched X-ray and radio epochs and obtain comparable correlations to the matched data. Hence, we find no overall statistical evidence that X-ray flares and radio variability are correlated, underscoring a need for more simultaneous, long duration X-ray–radio monitoring of Sgr A*.
Robust Cross-correlation-based Measurement of Clump Sizes in Galaxies

Published: August 2017

Abstract
Stars form in molecular complexes that are visible as giant clouds (

) in nearby galaxies and as giant clumps (

) in galaxies at redshifts

–3. Theoretical inferences on the origin and evolution of these complexes often require robust measurements of their characteristic size, which is hard to measure at limited resolution and often ill-defined due to overlap and quasi-fractal substructure. We show that maximum and luminosity-weighted sizes of clumps seen in star formation maps (e.g., Hα) can be recovered statistically using the two-point correlation function (2PCF) if an approximate stellar surface density map is taken as the normalizing random field. After clarifying the link between Gaussian clumps and the 2PCF analytically, we design a method for measuring the diameters of Gaussian clumps with realistic quasi-fractal substructure. This method is tested using mock images of clumpy disk galaxies at different spatial resolutions and perturbed by Gaussian white noise. We find that the 2PCF can recover the input clump scale at

accuracy, as long as this scale is larger than the spatial resolution. We apply this method to the local spiral galaxy NGC 5194, as well as to three clumpy turbulent galaxies from the DYNAMO-HST sample. In both cases, our statistical measurements of Hα clump size agree with previous measurements and with the estimated Jeans lengths. However, the new measurements are free from subjective choices when fitting individual clumps.
Off‐fault heterogeneities promote supershear transition of dynamic mode II cracks
Authors: Albertini Gabriele , Kammer David S. 
Published: August 2017

AbstractThe transition from sub‐Rayleigh to supershear propagation of mode II cracks is a fundamental problem of fracture mechanics. It has extensively been studied in homogeneous uniform setups. When the applied shear load exceeds a critical value, transition occurs through the Burridge‐Andrews mechanism at a well‐defined crack length. However, velocity structures in geophysical conditions can be complex and affect the transition. Damage induced by previous earthquakes causes low‐velocity zones surrounding mature faults and inclusions with contrasting material properties can be present at seismogenic depth. We relax the assumption of homogeneous media and investigate dynamic shear fracture in heterogeneous media using two‐dimensional finite element simulations and a linear slip‐weakening law. We analyze the role of heterogeneities in the elastic media, while keeping the frictional interface properties uniform. We show that supershear transition is possible due to the sole presence of favorable off‐fault heterogeneities. Subcritical shear loads, for which propagation would remain permanently sub‐Rayleigh in an equivalent homogeneous setup, will transition to supershear as a result of reflected waves. P wave reflected as S waves, followed by further reflections, affect the amplitude of the shear stress peak in front of the propagating crack, leading to supershear transition. A wave reflection model allows to uniquely describe the effect of off‐fault inclusions on the shear stress peak. A competing mechanism of modified released potential energy affects transition and becomes predominant with decreasing distance between fault and inclusions. For inclusions at far distances, the wave reflection is the predominant mechanism.
Intermetallic Compounds and Alloy Bonding Theory Derived from Quantum Mechanical One‐Electron Models
Authors: Lee Stephen , Fredrickson Daniel C. 
Published: August 2017

AbstractThis chapter traces, to the current day, one‐electron quantum mechanical concepts as applied to intermetallic compounds and alloys. Three main threads are followed: the evolution over time of the tight‐binding model, the role of nearly free‐electron theory, and the adaption of one‐electron ideas to experimentally derived phenomenological theories as applied to these systems.Analysis of tight‐binding theory begins with the two‐electron bond: The case of hydrogen is contrasted to the alkali metals. The connection between tight‐binding theory and density functional theory is explored: Tight‐binding theory is found to reproduce well the more computationally precise DFT band structures. Models that emanate from tight‐binding theory include the COOP and COHP analysis of the metallic bond, site preferences (the coloring problem), and Mulliken populations. Tight‐binding moment theory is also shown to account for crystalline structural preferences. The Dronskowski–Landrum model for magnetically ordered systems is presented. Recent developments focused on localized orbitals (Wannier functions), and transition metal electron‐counting (for half‐Heusler, Nowotny chimney ladder phases, and other phases) is explored. Reversed approximation molecular orbital analysis to these latter systems is presented.The role of nearly free electron theory and its role in the understanding of Hume‐Rothery electron phases is presented. The importance of the Jones zone is made clear, not just for these phases but also for more complex phases, including the Samson phase, Cd3Cu4, with 1124 atoms in its unit cell. Recent work combining the Jones model of orbital mixing with the Zintl concept of electropositive to electronegative atom electron transfer is found to lead to corrected Jones zones for the quasi‐crystalline approximant phase Li52.0Al88.7Cu19.3. An explanation of the unusual electron count of the 1e−/aγ‐brass structure Li33Ag19is derived. The role of pseudopotentials in accounting for structural distortions is reviewed.Finally, a look at how well‐known phenomenological analyses have evolved into modern quantum theory‐based models is explored. Among these is the role of structure maps, where the Pettifor tight‐binding model for structure maps is presented. The phenomenological Pearson analysis of steric strain is shown to lead to chemical pressure analysis via ‐based Hückel theory. The classic Brewer analysis of electron transfer from electropositive to electronegative atoms evolves into the ‐Lewis acidity model.
Quasicrystal Approximants
Authors: Lidin Sven 
Published: August 2017

AbstractThe concept of quasicrystal approximants is best pursued with reference to the quasicrystals themselves. This makes the classification of approximants into classes congruent to those for quasicrystals useful, that is, axial and icosahedral. As noted by several authors, work on approximants has come full circle; the initial interest in approximants grew out of a desire to understand particularly the enigmatic structure of the quasicrystals, but lately it has become increasingly clear that not only the structure but also many of the physical properties of quasicrystals may be more conveniently probed and understood through the study of their approximants. Although the uniqueness of quasicrystals lies in their structures, the approximants approximate this to such an extent that most questions about quasicrystals can be addressed through the proxy of the approximant phases. This treatise deals mainly with the structural properties of approximants.
Introduction to the Crystal Chemistry of Transition Metal Oxides
Authors: Greedan J.E. 
Published: August 2017

AbstractAn attempt is made to introduce the subject of the structure of the vast class of materials known as transition metal oxides (TMO). Transition metals are defined as members of the d and f groups in the periodic table. After the introduction of a core of principles, which determine the crystal structure of TMO, six of the most important structure types and structures derived from these are presented: NaCl or rock salt‐, corundum‐, rutile‐, fluorite‐, perovskite‐, and spinel structures. Many examples are described with the use of 50 figures, 11 tables, and 186 references. Connections between structure and properties, both physical and chemical, are discussed.
High‐Pressure Methods in Solid‐State Chemistry
Authors: Huppertz Hubert , Heymann Gunter , Schwarz Ulrich , Schwarz Marcus R. 
Published: August 2017

AbstractSolid‐state chemistry exhibits an intriguing variety of methods for the syntheses of new materials. The majority of these methods deal with variations of the reactive compounds including an enhancement of the temperature. The latter factor provides the reactions with the essential kinetic energy as one of the most important factors for a successful solid‐state synthesis. An alternative or additional route to supply the synthesis of solids with the necessary reaction energy is the use of high pressures. Technically, this way is much more demanding due to the fact that the stabilization of such extreme conditions requires sophisticated devices. This chapter will introduce into the main techniques of high‐pressure solid‐state chemistry giving a brief overview of the assets and drawbacks of each method. Additionally, the main principles of high‐pressure chemistry are explained including a chapter of recent advances in the field of high‐pressure solid‐state chemistry.
