Authors: Ardiansyah Arief , Asfiyak Khoirul 
Published: June 2020

Multimedia learning has been widely used as a medium of learning in the classroom as its effectiveness in improving student learning outcomes. However, there are still many schools unable to develop and implement it, due to the lack of knowledge and skills of teachers in developing it, the unavailability of means to implement it, and the absence of special training to develop it. This program aims to provide training in designing and developing interactive learning multimedia for teachers at Bajangan Elementary School, Pasuruan Regency. Using the guided tutorial method which is directly guided by an expert trainer, found that the final result of the training is that the teachers are able to develop multimedia interactive learning independently in accordance with the characteristics of their field of study. The evaluation process, by visiting the school one week after the training activities and by looking at multimedia learning programs, shows that the program has been successfully developed by the teachers.

Published: June 2020

A educação é a base do crescimento e do desenvolvimento de qualquer sociedade. Em Angola não é exceção. Mas, a situação da corrupção na escola primária e secundária angolana é preocupante porque reduz a qualidade de ensino e provoca descredibilidade da escola. O artigo parte do questionamento: Quais seriam os fatores que contribuem para a corrupção nas escolas secundarias de Angola? Visa, ainda, analisar, refletir e repensar sobre os problemas da corrupção que estão presente no setor da educação angolana. Utilizando o método bibliográfico, se concluiu que é necessário que o Governo de Angola adote políticas educacionais que ajudem na melhoria da qualidade de ensino. É importante que o Governo aposte na formação dos professores com qualidade, melhorando as condições infraestruturais das escolas fato que vai diminuir a procura de vagas de matrícula. Os pais devem assumir a responsabilidade da escola participando do processo escolar e apoiando os professores e os alunos. As escolas devem receber todo apoio do Governo por forma a que a educação seja de qualidade e para todos.

Abstract
We report the 6.5σ detection of water from the hot Jupiter HD187123b with a Keplerian orbital velocity K

p
of 53 ± 13 km s−1. This high-confidence detection is made using a multi-epoch, high-resolution, cross-correlation technique, and corresponds to a planetary mass of

M
J and an orbital inclination of 21° ± 5°. The technique works by treating the planet/star system as a spectroscopic binary and obtaining high signal-to-noise, high-resolution observations at multiple points across the planet’s orbit to constrain the system’s binary dynamical motion. All together, seven epochs of Keck/NIRSPEC L-band observations were obtained, with five before the instrument upgrade and two after. Using high-resolution SCARLET planetary and PHOENIX stellar spectral models, we were able to drastically increase the confidence of the detection by running simulations that could reproduce, and thus remove, the nonrandom structured noise in the final likelihood space well. The ability to predict multi-epoch results will be extremely useful for furthering the technique. Here, we use these simulations to compare three different approaches to combining the cross correlations of high-resolution spectra and find that the Zucker log(L) approach is least affected by unwanted planet/star correlation for our HD187123 data set. Furthermore, we find that the same total signal-to-noise ratio (S/N) spread across an orbit in many, lower S/N epochs rather than fewer, higher S/N epochs could provide a more efficient detection. This work provides a necessary validation of multi-epoch simulations, which can be used to guide future observations and will be key to studying the atmospheres of farther separated, non-transiting exoplanets.

Published: June 2020

Abstract
NASA’s WB-57 High Altitude Research Program provides a deployable, mobile, and stratospheric platform for scientific research. Airborne platforms are of particular value for making coronal observations during total solar eclipses because of their ability both to follow the Moon’s shadow and to get above most of the atmospheric air mass that can interfere with astronomical observations. We used the 2017 August 21 eclipse as a pathfinding mission for high-altitude airborne solar astronomy, using the existing high-speed visible-light and near/midwave infrared imaging suite mounted in the WB-57 nose cone. In this paper, we describe the aircraft, the instrument, and the 2017 mission; operations and data acquisition; and preliminary analysis of data quality from the existing instrument suite. We describe benefits and technical limitations of this platform for solar and other astronomical observations. We present a preliminary analysis of the visible-light data quality and discuss the limiting factors that must be overcome with future instrumentation. We conclude with a discussion of lessons learned from this pathfinding mission and prospects for future research at upcoming eclipses, as well as an evaluation of the capabilities of the WB-57 platform for future solar astronomy and general astronomical observation.
AGN X-Ray Irradiation of CO Gas in NGC 2110 Revealed by Chandra and ALMA
Authors: Kawamuro Taiki , Izumi Takuma , Onishi Kyoko , Imanishi Masatoshi , Nguyen Dieu D. , Baba Shunsuke 
Published: June 2020

Abstract
We report spatial distributions of the Fe–Kα line at 6.4 keV and the CO(J = 2–1) line at 230.538 GHz in NGC 2110, which are, respectively, revealed by Chandra and Atacama Large Millimeter/submillimeter Array (ALMA) at ≈0.″5. A Chandra 6.2–6.5 keV to 3.0–6.0 keV image suggests that the Fe–Kα emission extends preferentially in a northwest to southeast direction out to ≈3″, or ∼500 pc, on each side. Spatially resolved spectral analyses support this by finding significant Fe–Kα emission lines only in the northwest and southeast regions. Moreover, their equivalent widths are found to be ∼1.5 keV, indicative for the fluorescence by nuclear X-ray irradiation as the physical origin. By contrast, CO(J = 2–1) emission is weak therein. For quantitative discussion, we derive ionization parameters by following an X-ray dominated region (XDR) model. We then find them high enough to interpret the weakness as the result of X-ray dissociation of CO and/or H2. Another possibility also remains that CO molecules follow a superthermal distribution, resulting in brighter emission in higher-J lines. Further follow-up observations are encouraged to draw a conclusion on what predominantly changes the interstellar matter properties and whether the X-ray irradiation eventually affects the surrounding star formation as active galactic nucleus (AGN) feedback.
New Type Ia Supernova Yields and the Manganese and Nickel Problems in the Milky Way and Dwarf Spheroidal Galaxies
Authors: Kobayashi Chiaki , Leung Shing-Chi , Nomoto Ken’ichi 
Published: June 2020

Abstract
In our quest to identify the progenitors of Type Ia supernovae (SNe Ia), we first update the nucleosynthesis yields for both near-Chandrasekhar- (Ch) and sub-Ch-mass white dwarfs (WDs) for a wide range of metallicities with our 2D hydrodynamical code and the latest nuclear reaction rates. We then include the yields in our galactic chemical evolution code to predict the evolution of elemental abundances in the solar neighborhood and dwarf spheroidal (dSph) galaxies Fornax, Sculptor, Sextans, and Carina. In the observations of the solar neighborhood stars, Mn shows an opposite trend to α elements, showing an increase toward higher metallicities, which is very well reproduced by the deflagration–detonation transition of Ch-mass WDs but never by double detonations of sub-Ch-mass WDs alone. The problem of Ch-mass SNe Ia was the Ni overproduction at high metallicities. However, we found that Ni yields of Ch-mass SNe Ia are much lower with the solar-scaled initial composition than in previous works, which keeps the predicted Ni abundance within the observational scatter. From the evolutionary trends of elemental abundances in the solar neighborhood, we conclude that the contribution of sub-Ch-mass SNe Ia to chemical enrichment is up to 25%. In dSph galaxies, however, larger enrichment from sub-Ch-mass SNe Ia than in the solar neighborhood may be required, which causes a decrease in [(Mg, Cr, Mn, Ni)/Fe] at lower metallicities. The observed high [Mn/Fe] ratios in Sculptor and Carina may also require additional enrichment from pure deflagrations, possibly as SNe Iax. Future observations of dSph stars will provide more stringent constraints on the progenitor systems and explosion mechanism of SNe Ia.
L’apparition de la monnaie frappée : invention ou innovation ? Bilan historiographique et enjeux historiques
Authors: Hochard Pierre-Olivier 
Published: June 2020

Résumé : La monnaie frappée n’est finalement qu’un objet monétaire parmi d’autres. Son apparition est-elle donc une invention ou une innovation ? Les spécialistes de la monnaie se sont posés la question des origines (où, quand, comment et pourquoi ?), et de ce que fait la monnaie. Les sciences historiques se sont cependant peu interrogées sur ce qu’ est la monnaie (quoi ?). Questionner la naissance de la monnaie frappée, c’est pourtant se pencher sur ce qu’est le phénomène monétaire, qui ne saurait se réduire ou être réduit à sa seule dimension économique ou anthropologique.
Entre innovation et tradition. Remarques sur le monnayage romain des origines à l’avènement de l’Empire
Authors: Suspène Arnaud 
Published: June 2020

Résumé : La monnaie frappée est une innovation tard venue à Rome. Elle subit en outre de profonds et violents changements qui la conduisent, après des débuts discrets, à devenir une des structures majeures de l’Empire. Ces métamorphoses et ces changements d’échelles sont minorés dans les sources, qui insistent au contraire sur la continuité de l’histoire monétaire romaine pour des raisons tenant à la fois aux valeurs de la société romaine elle-même et aux caractéristiques de la monnaie.
Imiter, innover. L’adoption de la monnaie d’or frappée en Gaule celtique, III e siècle avant notre ère
Authors: Nieto-Pelletier Sylvia 
Published: June 2020

Résumé : Cet article a pour objectif de repenser l’introduction de la monnaie d’or frappée en Gaule au iii e siècle avant notre ère et de proposer des pistes de réflexion quant à la fonction des premières émissions gauloises en or, les « imitations du statère aux types de Philippe II de Macédoine », et la question des autorités émettrices. Entre imitation et innovation, il s’agit de replacer l’adoption de la monnaie d’or gauloise dans le contexte des sociétés celtiques des iv e - iii e siècles avant notre ère et en étroite corrélation avec les émissions gréco-macédoniennes qui leur ont servi de modèles.

Authors: Théret Bruno 
Published: June 2020

Résumé : En Argentine, entre 1890 et 2003, un nombre conséquent de Provinces ont émis des monnaies complémentaires à la monnaie fédérale de cours légal sous forme de billets de petites dénominations. L’article décrit ce phénomène largement ignoré. Après avoir analysé les caractéristiques générales de ces monnaies fiscales complémentaires et les raisons du désintérêt des économistes et historiens à leur égard, on en décrit les quatre vagues d’émission. Enfin on présente la diversité des types d’instruments qui ont été expérimentés et les liens qui peuvent exister entre les formes de monnayage choisies et les succès ou échecs des dispositifs.
La construction métropolitaine au sud du Viêt-nam
Authors: Tran Khac Minh 
Published: June 2020

Depuis les réformes du Đôi Moi (renouveau) de 1986, la région de Hô Chi Minh-Ville est devenue le fer de lance de l’économie vietnamienne. Les rapports de force au sein de cette région, historiquement marquée par l’importance dominante de Hô Chi Minh-Ville, se transforment en profondeur, avec la création de nouveaux corridors urbano-industriels interprovinciaux. Dans quelle mesure ces nouvelles dynamiques spatio-économiques sont-elles révélatrices de la sélectivité territoriale de la métropolisation, ainsi que du caractère fragmentaire de la construction régionale au sud du Viêt-nam ? Cet article éclaire les processus par lesquels les recompositions à l’échelle locale, profondément marquée par des logiques concurrentielles, ont contribué à renforcer les liens entre provinces au sein de cette région urbaine.
La lutte narrative pour la signification et la politisation de « l’Europe » dans les négociations du TTIP : le récit de l’Europe bouclier contre le populisme transnational
Authors: Oleart Alvaro , Bouza García Luis 
Published: June 2020

Les études européennes connaissent actuellement un tournant narratif (Biegoń, 2013 ; Bouza Garcia, 2017). Le débat académique commence à tenir compte de l’importance des représentations socioculturelles de l’Union européenne pour comprendre les attitudes des citoyens et de la société civile envers l’UE, et de l’utilisation de stratégies narratives par les acteurs politiques de l’UE. Afin de contribuer à analyser la manière dont l’Europe est racontée dans l’environnement politisé actuel, nous examinons la compétition pour définir « l’Europe » dans le contexte du Partenariat transatlantique de commerce et d’investissement (TTIP en anglais), en analysant les stratégies narratives concurrentes de la Commission européenne et de la coalition Stop TTIP. Nous analyserons les récits proposés dans les documents stratégiques des deux camps, en concevant ces deux récits antinomiques comme une opposition entre « l’Europe bouclier » et le « populisme transnational ». Nous présenterons également des entretiens approfondis avec des représentants des élites politiques bruxelloises afin de faire apparaître l’articulation de ces récits.
The Heroes and Villains of an Alternative Europe – How EU Contestation shapes Narratives of Europe in Germany
Authors: Conrad Maximilian , Hallgrímsdóttir Helga Kristín , Brunet-Jailly Emmanuel 
Published: June 2020

Cet article analyse la contribution de la contestation contre l’UE à une narration alternative de l’Europe. Se fondant sur des théories de l’euroscepticisme, l’article soutient que la contestation contre l’UE ne nécessite pas d’être basée sur un rejet fondamental de l’intégration européenne. En effet, elle peut faire une contribution constructive à une vision alternative de l’Europe en accentuant des valeurs comme la solidarité, la démocratie, les droits humains ou la protection de l’environnement. L’analyse empirique soutient cet argument en démontrant comment la contestation de l’UE en Allemagne a évoqué des images de « héros » et de « scélérats » d’une Europe alternative.
Speaking for “the European people”? How the transnational alliance Fortress Europe constructs a populist counter-narrative to European integration
Authors: Volk Sabine 
Published: June 2020

Cet article examine un des rares cas de populisme transnational dans le contexte de la (dés)intégration européenne, en se concentrant sur le mouvement d’extrême droite Fortress Europe (« l’Europe forteresse »). En utilisant de nouvelles sources primaires telles que des textes numériques, des images et des vidéos, l’article effectue une analyse critique du discours et des performances de Fortress Europe. L’analyse révèle comment l’alliance construit l’Europe en tant que société en guerre contre « les immigrants » et ses « élites ». Au-delà, l’article considère la construction discursive de l’Europe sous l’angle du populisme transnational, en soulignant les succès et les échecs de l’alliance dans la construction d’un « peuple » transnational. Enfin, il discute de manière critique de la forteresse européenne dans le contexte de la politique européenne dominante.
Narrating into Europe: Female Migrant Writers’ Voice and Representation
Authors: van Amelsvoort Jesse 
Published: June 2020

Cet article étudie The Embassy of Cambodia de Zadie Smith et L’últim patriarca de Najat El Hachmi, qui thématisent ce que Stuart Hall appelle “être dans, mais pas de l’Europe”. À travers des protagonistes qui sont toutes les deux des jeunes femmes, ces récits capturent et illustrent les changements en Europe amenés par les migrations et la mondialisation. En tant qu’œuvres littéraires, à travers le récit, ces fictions exemplifient la difficulté qu’ont les femmes migrantes à trouver leur place dans l’Europe contemporaine, et suggèrent que le récit est un moyen de prendre position et de s’engager vis-à-vis des défis majeurs que présente cette Europe. Ce n’est qu’en réécrivant l’histoire que les femmes migrantes peuvent, finalement, l’embrasser.
The social imaginary of precarious Europeans: the cultural representation of European socio-economic precarity in Tascha and Bande de Filles
Authors: van der Waal Margriet 
Published: June 2020

Cette contribution s’intéresse à la manière dont deux textes artistiques représentent des Européens en situation de précarité : des sujets sociaux vulnérables (citoyens, habitants de l’Europe/UE) qui peuvent être considérés comme des « perdants » du projet européen. Ces personnes précaires sont rarement - voire pas du tout - représentées en tant que participants aux processus complexes de l’européanisation. Les textes analysés et discutés dans cette contribution sont le roman néerlandais Tascha de Mira Feticu (2015) et le long métrage français, Bande de Filles de Céline Sciamma (2014). Je soutiens qu’une analyse critique de ces récits nous permet d’ouvrir la catégorie des « Européens » et nous pousse à repenser qui est considéré comme « Européen ».
Adaptive Optics Ophthalmoscopy
Authors: Roorda Austin 
Published: June 2020

ABSTRACT
Retinal images in the human eye are normally degraded because we are forced to use the optical system of the human eye- which is fraught with aberrations - as the objective lens. The recent application of adaptive optics technology to measure and compensate for these aberrations has produced retinal images in human eyes with unprecedented resolution. The adaptive optics ophthalmoscope is used to take pictures of photoreceptors and capillaries and to study spectral and angular tuning properties of individual photoreceptors. Application of adaptive optics technology for ophthalmoscopy promises continued progress toward understanding the basic properties of the living human retina and also for clinical applications.

Application of micro-PIXE (particle induced X-ray emission) to study buckwheat grain structure and composition
Authors: Pongrac Paula , Kelemen Mitja , Vavpetič Primož , Vogel-Mikuš Katarina , Regvar Marjana , Pelicon Primož 
Published: June 2020

Tartary buckwheat (Fagopyrum tataricum Gaertn.) is a gluten-free pseudo-cereal crop with a grain nutrient profile that makes it an excellent alternative foodstuff. The distribution of calcium (Ca), magnesium (Mg), phosphorus (P) and sulphur (S) was investigated by micro-PIXE (particle induced X-ray emission) to resolve allocation and concentration of the elements in nine distinct grain tissues. Magnesium, P and S were preferentially allocated to the cotyledons and the embryonic axis (both inner and outer tissues), and Ca was predominant in the pericarp where two Ca-rich layers were observed. Allocation of P and S to aleurone suggests that this layer of cells, although not as prominent as in cereal grain, is rich in phytate and proteins. Quantitative information on spatial distribution of mineral elements in the edible grain may be useful in the technological processing of the grain and particularly in reducing the amount of mineral-element loss during milling.
Case-Based Analogical Reasoning: A Pedagogical Tool for Promotion of Clinical Reasoning
Authors: Speicher Timothy E. , Bell Alexandra , Kehrhahn Marijke , Casa Douglas J. 
Published: June 2020

Context: One of the most common instructional methods utilized to promote learning transfer in health profession education is examination of a single patient case. However, in non-healthcare settings this practice has shown to be less effective in promoting learning than the examination of multiple cases with cueing.
Objective(s): The primary objective of this article is to provide athletic training educators a rationale for implementing a multiple case-based analogical reasoning technique to improve students' learning transfer.
Background: Case-based analogical reasoning is a pedagogical technique that improves problem solving by helping learners identify a common structural principle shared among multiple cases. Identification and transfer of the shared principle facilitates solving novel problems or patient cases. When cueing is coupled with the process, transfer of the structural principle to the problem is enhanced.
Description: This article discusses cognitive learning theory and provides empirical evidence to support the use of case-based analogical reasoning to improve athletic training students' clinical reasoning. It also provides the educator practical tips for implementing the technique in classroom and clinical settings.
Clinical Advantage(s): Improving the transfer of structural principles may improve solving novel problems in the clinical environment, which should also improve the quality of patient care.
Conclusions: Clinical reasoning and learning transfer may be improved among health professional students during a case-based analogical reasoning process when cued to look for the shared structural principle among cases. Students who engage in multiple-case examination with cueing may be more apt to recall their learning and use it when faced with novel cases in the clinical environment.
