Opportunities and challenges of dialogic pedagogy in art museum education
Authors: Dysthe Olga 
Published: May 2021

The aim of this interpretative, qualitative research study is to investigate affordances and constraints of dialogic pedagogy in the museums, as well as its broader contribution to society today. The background is my involvement in a Danish development project called ‘Museums and Cultural Institutions as Spaces for Citizenship,’ initiated by seven art museum educators in Copenhagen and supported by the Ministry of Culture. Denmark has a strong dialogic tradition dating back to Grundtvig’s belief in the power of ´the oral word’ to foster democratic ‘Bildung.’ Museum education, on the other hand, has a long tradition of monologic transmission. Still, a more participatory pedagogy has been gaining ground over many years.
This study is based on the observations of three-hour-long teaching sessions in seven museums and has a Bakhtinian framework. While the overall analysis builds on the whole project, two cases are discussed in more detail. The overarching research question is how central aspects of dialogic pedagogy played out in an art museum context and its opportunities and challenges. The subquestions focus on three central Bakhtinian concepts: How did the educators facilitate multivoicedness during the short museum visits? What role did difference and disagreement play? What opportunities emerged for students to develop internally persuasive discourse? I have chosen these concepts because they are central in dialogism and combined them because they are closely connected in Bakhtin’s work. The final reflections open a wider perspective of how dialogic museum education may contribute to overarching functions of education: qualification, socialization, and subjectification.
Key findings were that the museum educators’ transition from traditional to dialogic pedagogy was enhanced by their genuine interest in hearing students’ voices. They succeeded in engaging students in multivoiced dialogues but with a tendency towards harmonization rather than the exploration of diversity and difference. The practical aesthetic workshops offered unique opportunities for students to develop their internally persuasive word, i.e., by replacing authoritative interpretations of artworks with their own. Challenges experienced by the educators were, e.g., the dilemmas between preplanning and student choice and between disseminating their professional art knowledge and facilitating students’ meaning making and creativity. In contrast, students found the lack of workshop follow-up problematic.
The article provides deeper insight into museums as an alternative pedagogical arena. Museum educators and non-museum classroom teachers may find it useful for cultivating greater dialogic interactions in respective learning contexts.
BRDF-CORRECTED VEGETATION INDICES CONFIRM SEASONAL PATTERN IN GREENING OF FRENCH GUIANA’S FORESTS
Authors: Cherrington Emil A. 
Published: May 2021

Parmi les outils de caractérisation de la dynamique forestière, la télédétection est particulièrement adaptée pourl’observation des vastes surfaces forestières de Guyane d’accès difficile. Dans le but de réévaluer les hypothèses énoncées dans des études antérieures sur la capacité des capteurs optiques embarqués sur les satellites à détecter la dynamique de la phénologie, nous avons compilé sur une période de 12 années divers indices de végétation corrigés des effets bi-directionnels de variation des angles d’acquisition (BRDF). Ces indices sont issus de 2 capteurs optiques: SPOT VEGETATION, et MODIS (MODerate resolution Imaging Spectroradiometer). Les données ont été analysées pour évaluer les tendances saisonnières à l'échelle de l’ensemble de la Guyane et également sur quatre sites répartis sur ce territoire. Les données révèlent que les forêts de Guyane présentent un patron de saisonnalité. Le pic annuel des divers indices au cours de la période de septembre à octobre est interprété comme le reflet d’un pic de production de feuilles pendant la saison sèche.

Les phénomènes d'instabilité de versant, par leur caractère essentiellement aléatoire, génèrent des risques pour les divers éléments du patrimoine montagnard. Dans la région des montagnes de Man, située à l'Ouest de la Côte d'Ivoire, la manifestation de ces phénomènes se fait de plus en plus en raison du relief accidenté et de la forte pluviométrie (plus de 1500mm/an). Cette étude vise donc à cartographier des zones potentielles de mouvements d'instabilité de versant dans la région de Man en vue de prévenir les dégâts naturels et/ou de victimes. L'approche méthodologique utilisée dans ce travail est basé sur la télédétection, les systèmes d'information géographiques (SIG) et l'analyse multicritère (AHP) de Saaty. Six (6) facteurs impliqués dans l'occurrence des glissements de terrain à savoir l'inclinaison de pente, la densité de drainage, la densité de fracturation, l'épaisseur d'altérite, les précipitations et l'indice de végétation normalisé (NDVI) ont été cartographiés. Leur intégration dans un Système d'information géographique (SIG) a permis de cartographier l'indice de susceptibilité aux mouvements de terrain de la région. En effet, à l'aide de la méthode d'analyse multicritère de Saaty, une hiérarchisation, une pondération puis une classification des différents facteurs ont été faites. Cela a facilité la combinaison linéaire des différents facteurs dans le SIG. La carte d'indice de susceptibilité obtenue a fait l'objet de vérification sur le terrain pour aboutir à une carte de susceptibilité aux mouvements d'instabilité de terrain de la région de Man. Cette carte révèle des degrés d'instabilité : très faible, faible, moyen, élevé et très élevé. Les zones d'instabilité élevée et très élevée représentent 14,65% de la zone étudiée et sont intimement liées aux fortes pentes et précipitations dans le Centre-Ouest de la Région de Man. Ces zones sont situées majoritairement entre Biankouma et Man, occupant en partie, les versants des monts Toura et Dan.

Cette étude vise à détecter et cartographier la dégradation et la régénération de la couverture végétale durant ces deux dernières décennies en Haute-Casamance, située dans le sud du Sénégal. Elle s’appuie sur l’analyse des tendances de séries temporelles d’images MODIS NDVI acquises sur la période 2000-2018, sur la cartographie des changements d’occupation et d’utilisation des sols (LULCC) faite à partir d’images Landsat (ETM+ 1999 et OLI 2018), et sur une analyse conjointe des tendances de NDVI et LULCC. L’étude a révélé d’importants changements en termes d’occupation et d’utilisation des sols, notamment la conversion de la forêt à la savane (13,5 %), et de la savane aux zones de culture et d’habitat (7,9 %). Des tendances négatives significatives (p<0,1) du NDVI (en lien avec la conversion forêt-savane et forêt-zones de culture et d’habitat) sont observées sur 2,1% de la zone étudiée et indiquent une dégradation de la végétation en particulier le long de la frontière avec la Gambie, sur l’axe Pata-Ndorna, dans le centre de la zone d’étude, et autour de Médina Gounass. Par ailleurs, des tendances positives significatives (p<0,1) sur 1,8 %  de la surface de la zone d’étude témoignent de la régénération dans le sud et sont liées à la conversion des zones de culture en savane et en forêt. L’analyse conjointe des tendances NDVI et LULCC indique une dégradation significative au sud de Kerewane et de Niaming, sur l’axe Ndorna-Pata, autour de Médina Gounass, et vers Saré Coly ; et une régénération significative à la frontière nord-est, au nord de Mampatim, au sud vers Bagadadji et Médina El Hadji, et entre Linkering-Paroumba. Cette analyse a également révélé que les deux séries d’images (NDVI et Landsat) sont cohérentes spatialement et que l’essentiel des tendances de productivité de la végétation est expliqué par les changements d’utilisation des sols et non par le climat.

Today oil industry faces a lot of problems and lost money during drilling and completion operation, so that the studies and researches must including the ways and solutions that lead to decrease the costs.
In this research we tried to find local alternative material instead of foreign drilling fluid materials that is used in drilling fluids and will help to save a lot of money by decrease oil well drilling cost because of the high cost of drilling fluid materials which represent now about 30 % of total cost for drilling oil well.
The local alternatives is Ore polymers ( plant origin) called : TRAGACANTH GUM.
In this study we investigated the local material and tested it under API Specification for Drilling Fluids Materials. Also tested sample of mud after add local material (TRAGACANTH GUM.) for weighted concentrations (0.5, 1.5, 2, 2.5 and 3 gm.) to show physical and rheological properties.
The third part of this study tested sample of mud after add local material (TRAGACANTH GUM.) under different temperatures values and up to 70°C (this temperature is near for some formations temperature in Iraqi oil fields ) to show temperature effect on this material.
A comparison between the local alternative and similar foreign materials for same sample was done to show physical and rheological properties. The results approved that, the local alternatives can used as filtration control materials for water based drilling fluid. Also the local alternatives increased viscosity as minimal for water based drilling fluids, So it can be used as part alternative for Bentonite to increase viscosity by increasing Yield point and decreasing solids concentration in drilling fluids so it have positive effect to save Rig equipment’s and Pay-zone.

Research includes the study of the North West Extensions of Makhul structure using remote sensing techniques (central Iraq) which is located to the north of Baiji province in Salahuddin governorate, which lies 240 kilometers north of the city of Baghdad, located within the operations of the North Oil Company.
The aim of the present study is to re-define extensions of Makhul structure by the use of visual space (satellite systems and landsat7 ETM) after it was observed that there is a difference for determined the North West Extensions for structure of what is mentioned in previous studies.
I have been using the space visuals and available previous studies for the Makhul structure and North Western Extensions him in determining the dimensions, in addition to the show faults in the research area and relations with the Makhoul structure and its extensions. It has also been taking the results of wells drilled in the research area (Makhul -1, 2 and Mityaha -1), for the purpose of assessing hydrocarbon reservoir, and we are relying on the explanatory information from the images and spatial data and received from the satellite (LANDSAT 7) according to the system ETM (Enhasment Thematic Mapper). It has also rely on the definition and identification of some units geomorphologic home on the intensity of the color, tone and texture. a network of drainage pattern is essential.
Using satellite data and previous studies point showing that the length of the Makhul structure more than 95.500 km and not 37 km, and the area affected by the operations raise distinct and different stages. it has been divided into four parts of Makhul structure (from the southeast to the northwest), a south-eastern part, part crescent, which includes the Saded structure, the middle part, which includes the Cehel structure and north-western part, which includes the Mityaha structure. The hydrocarbon possibilities in the study area, it is in spite of the weakness of the possibilities hydrocarbon in the southeastern part of the Makhul structure (wells Makhul-1,2) and the northwestern part formerly known the Mityaha structure (well Mityaha -1), but the middle part (the structure Cehel areal) may be possibilities hydrocarbon better and more possibilities from the other parts.

Aim of the study was to investigate the risk of developing type 2 diabetes mellitus (T2DM) in individuals with metabolically healthy and unhealthy obesity phenotypes (MHO and MUO) and evaluate the contribution of metabolic syndrome (MS) components to the 12-year risk of developing T2DM according to a prospective study.Material and methods. The study included 1958 people with a BMI ≥30 kg/m² and no T2DM, from among those examined at the baseline screening in 2003– 2005 of the HAPPIE project. New cases of T2DM were diagnosed between 2003 and 2018 according to the register of diabetes mellitus and repeated screenings. The median follow-up period was 12.1 years. Were used to define MHO: criteria of the NCEPATP III, 2001 and IDF, 2005.Results. The incidence of T2DM in the MHO group according to all studied criteria is on 1,5 times lower than in persons with MUO, p<0,001. According to the results of Cox regression multivariate analysis, the risk of developing T2DM in individuals with MHO is 2.3 times lower according to the IDF criteria, 2005 and 2,2 times lower according to the NCEP ATP III, 2001 criteria, compared with persons with MUO. The risk of developing T2DM increases in direct proportion to the number of MS components: 3 components—OR = 3,1 (95% CI: 1.0; 9.9), p = 0.048, 4 components—OR = 4.4 (95% CI: 1.4; 14.0), p = 0.011. However, the presence of obesity in a person with one risk factor does not lead to the development of T2DM within 12 years, p>0.05. When analyzing obese individuals who had abdominal obesity (AO), the risk of developing T2DM is 2 times higher compared to individuals with normal waist circumference (WC), and people without AO demonstrate no risk of developing T2DM, with an increase in the number of MS components, p> 0.05.Conclusions. The incidence of first-­onset T2DM during 12 years in the MHO group by any used criteria is on 1.5 times lower than in the MUO group. In individuals with obesity, regardless of its phenotype, the most significant independent predictors of the risk of incident T2DM are AO and fasting hyperglycaemia. In individuals without AO, the risk of developing T2DM does not increase, even with an increase in the number of MS components. In the presence of AO, the risk of developing T2DM increases 2 times already with the appearance of any other component.

Diante dos resultados obtidos, recomenda-se o plantio de diferentes espécies nas Zonas Central e Sul da cidade.
¿Viaje desde el encantamiento hasta el desencantamiento? Un estudio sobre las descripciones de la naturaleza de Darwin desde el Journal hasta el Origin
Authors: Jiménez Pazos Bárbara 
Published: May 2021

Teniendo en cuenta la cuestión en disputa sobre el encantamiento o el desencantamiento del mundo causado por la ciencia moderna, este artículo examina comparativamente la semántica del léxico en Journal of Researches y The Origin of Species de Charles Darwin utilizando estrategias de minería de textos. El objetivo es mostrar que existe un camino semántico directo, comenzando en Journal y culminando en Origin, que confirma una tendencia hacia un tipo de lenguaje desencantado empleado por Darwin en sus descripciones de la naturaleza. Esto queda demostrado por el análisis léxico y semántico de ambos textos.
Taking into accountthe disputed question about enchantment or disenchantment of the world caused by modern science, this paper comparatively examines the semantics of the lexicon of Charles Darwin’s Journal of Researches and The Origin of Species using the software package Wordsmith Tools. Its aim is to show that there is a direct semantic path, starting with the Journaland culminating in the Origin, which confirms a tendency towards a gradually disenchanting, in a non-pejorative sense, type of language used by Darwin in his descriptions of nature. This is demonstrated by the lexical and semantic analysis of the texts.
imposible duelo o la traición más justa.
Authors: Agüero Águila Enrique Javier 
Published: May 2021

El siguiente trabajo profundiza el acontecimiento del duelo en la filosofía de Jacques Derrida. En esta perspectiva, se comienza por el libro Glas de 1974, donde se anunciaría el duelo por la muerte del sentido. Posteriormente, se profundizará en los fantasmas derridianos y la responsabilidad con los desaparecidos. En tercer lugar, emerge la figura del don, que abre al duelo hacia la espera infinita. Finalmente, y desde la lectura derridiana de los psicoanalistas Abraham y Török, se trabajará la figura de la “cripta” como falso inconsciente. Se concluye con una reflexión sobre Chile y los desaparecidos por la dictadura de Pinochet.
This article focus on the event of mourning in the philosophy of Jacques Derrida. It begins, accordingly, with the 1974 book Glas, where Derrida announces his mourning for the death of meaning. The article then focus on the Derridean ghosts and the responsibility towards the missing. Thirdly, the figure of gift emerges, one that opens mourning towards the infinite hold. Endly, from the Derridean lecture of phsychoanalysts Abraham and Török, the figure of “crypt” will be presented as a false inconscious. It concludes with a reflection on Chile and the missing people by Pinochet’s dictatorship.
