Image classification is a process where images are classified based on its visual content. It came into existence to reduce the gap between computer vision and human vision. To classify the images, humans involve lot of efforts and it is time consuming, in order to overcome this, technique such as convolutional neural network and random forest is being used. Convolutional neural network is a class of deep neural network and it is most commonly used for analyzing the images. Random forest is classification algorithms which consist of many independent decision trees. Auto encoding technique is being used to denoise the image. Image inpainting technique is adopted to come up with a complete image which contains missing parts. Image inpainting technique is a process to overcome overfitting.

The concept of sustainability for roof structure becomes most effective because slab consumes the highest amount of cement and steel in the building. This increases carbon footprint, which is a measure of the impact caused by the utilization of natural resources, eventually affecting the earth, and it becomes a subject of higher cost also. The objective of the paper is to find a safe, economical and sustainable roofing structure suitable for suburban and rural settlements. The literature survey carried out deeply and the potential is observed in tile vaulted structures. The core reasons behind adopting a vaulted structure are, it avoids using steel and concrete materials in construction, utilizes local labour, and low-cost local materials for construction. This predominantly becomes the primary factor in deciding the construction of an economical roofing structure for multiple dwelling units in rural and suburban settlements to provide a safe, sustainable and maintenance-free roofing system using tile vaulted structure.

Problematic soil which cause extra problems from engineering point of views which result in its composition or environmental conditions change. The weak subsoil deposits like soft clay pose the low bearing capacity and more settlements over long periods of time. The stone column technique is better, economical and cost-effective method of soft soil stabilization. They are used to support embankments, large raft foundations and isolated footings. Numerous researchers have just completed various vertical stacking probes stone column balanced out clay bed and have discovered that expands bearing capacity of delicate clay, diminishes displacement and changes the conduct of burden settlement. In the current study, a 2D finite element model is completed to evalute how the delicate clay soil balanced out by stone column are affected by the vertical burdens. Stone column were intended for examinations with fluctuating in their angle proportions (change in estimations of length, L and breadth, D) of stone column. The effect of floating stone column and end bearing stone segment on delicate clay is in like manner controlled by using various L/D ratios. Besides, the present outcomes express how the heap conveying limit of stone column is differed by changing in the angle proportions of the stone column. Likewise ends were drawn that bulging impact of stone column plays a vital role in conveying vertical burden.

Alkali-activated concrete (AAC) is mounting as a feasible alternative to OPC assimilated to reduce greenhouse gas emanated during the production of OPC. Use of pozzolana results in gel over-strengthening and fabricate less quantity of Ca(OH)2 which provide confrontation to concrete against hostile environment. (AAC) is potential due to inheriting the property of disbursing CO2 instantly from the composition. Contrastingly an option to ordinary Portland cement (OPC), keeping this fact in mind the goal to evacuate CO2 emits and beneficiate industrial by-products into building material have been taken into consideration. Production of alkali-activated cement emanates CO2 nearly 50-80% less than OPC. This paper is the general assessment of current report on the fresh and hardened properties of alkali-activated fly ash (AAF), alkali-activated slag (AAS), and alkali activated slag and fly ash (AASF) concrete. In the recent epoch, there has been a progression to blend slag with fly ash to fabricate ambient cured alkali-activated concrete. Along with that the factors like environmental friendliness, advanced studies and investigation are also mandatorily required on the alkali activated slag and fly ash concrete. In this way, the slag to fly ash proportion impacts the essential properties and practical design of AAC. This discusses and reports the issue in an intensive manner in the following sections. This will entail providing a good considerate of the following virtues like workability, compressive strength, tensile strength, durability issues, ambient and elevated-temperature curing of AAC which will improve further investigation to elaborate the correct test methods and to commercialize it.

This research is discussing about the construction project scheduling that is integrated between the implementation time with the resources needed periodically and in total. Because, determining the time of implementation of construction is very important as a basic reference, when the commencement of work and when the work must be completed. So far, the project scheduling method that is often used by engineers is the time schedule bar chart method, S curve method, Critical Path Method (CPM) method and other methods. After that, the time schedule is developed into scheduling material procurement and manpower, but the scheduling planning system is often out of sync with the implementation time schedule, material supply schedule and manpower supply schedule, therefore construction project delays often occur due to improper supply of material and manpower. That is part of the cause of the loss, therefore there needs to be an integrated scheduling program. How to produce an integrated program is, conducting research by combining methods namely, time schedule bar chart method, S curve method, CPM method, BOW analysis, SNI analysis, statistics, and supported by 60 random sampling data of project documents, consisting of, construction drawings, BOQ, and cost budget plan. Through the process according to these methods, an integrated program will be produced. Why is it necessary to use a program that results from this research, because this program is easy to use, simply enter the building area and planned implementation time at the input layer, the implementation schedule, and the required resources, will be detected automatically, both periodically and in total. This program uses Microsoft Excel applications and is very simple. This program can only be used for scheduling residential construction projects 1 level to 2 levels, with a building area between 36 m2 to 290 m2. Cannot be used in other projects because each construction project has different characteristics.

Traffic congestion is a normal phenomenon associated with transportation on the road at the same time which is hinder motion and need extra time to reach destinations. Congestion is one of the problems involving road. Normally, network congestion occurs on land transport on roads. As demand approaches the capacity of a road or of the intersection along the road, extreme traffic congestion will sets in. When vehicles are fully stopped for periods of time, this is colloquially known as a traffic jam or snarl-up. Traffic congestion can lead to drivers becoming frustrated and engaging in road rage. In this study of developing congestion index for heterogeneous traffic at the road stretch from Navalur to Kelambakkam and Kelambakkam to Navalur, the study initially focuses on the identification of factors affecting traffic congestion, and finding the most vulnerable location for congestion by developing a congestion index based on speed and saturation degree, with these two important approach solution of each area is suggested. To calculate the traffic congestion index, a thorough literature review has been conducted and all the possible parameters are identified. A questionnaire was prepared with relevant factors affection congestion and distributed to the people, who are resident or frequent users. The most significant factors are considered for further study to avoid congestion. Lack of number of lanes, no pedestrian pathway, on road parking, location of toll were found to be the most affecting factors, so we suggest widening of roads, effective parking system , etc. It is also observed that particular area of Padur and Kelambakkam were the main concern of traffic congestion. This is confirmed both practically and theoretically with the help of the survey and the congestion index values.

Experimental Work for Evaluation the Time Saving Between Different GPS Techniques for Makkah- Jeddah Region
Authors:   Civil Engineering Department, National Research Centre, Egypt(NRC)., Abdel-Wahab* A. M.
Published: July 2020

Nowadays, there are available in technology, devices, Techniques such as GNSS and CORS and use the VRS techniques. Although for previous technology, some application just needs for the ordinary GPS techniques. So, the current research work is done by field experiments to assess the time saving and accuracy between GPS different techniques such as Stop & Go, Kinematic, and Kinematic ON THE FLY Techniques especially in mountain areas like MAKKAH region. There are three post-processed GPS kinematic techniques. These techniques are stop &go, kinematic, and kinematic on the fly techniques. Stop& go and kinematic techniques require the so-called initialization process, which must be repeated in each cycle slip due to satellite-signal blockage. This is a time consuming and practically reduces the surveying productivity. On the other hand, the kinematic on the fly technique does not require the initialization process. This leads to increase the surveying productivity. The current paper makes a comparative study between GPS stop &go, kinematic, and kinematic on the fly techniques, from points of view of accuracy, time elapsed for the initialization process, observation time for each surveyed point and the surveying productivity. The results supported by appropriate statistical tests showed that positional discrepancies between stop-go and kinematic techniques have mean value of 22 mm  (S.D) of ± 7 mm. Also, the positional discrepancies between the stop& go and kinematic on the techniques are statically and practically insignificant, where the results showed that the positional discrepancy between the two techniques has a mean value of 22 mm with  (S.D) of ± 2 mm. In this context, the kinematic on the fly technique is increasing the surveying due to using a recording data of about 3-seconds for each surveying point, and also because this technique does not require any initialization process which takes a lot of time especially in case of surveying near tree, road, mountains, and advertising frames specially when internet and communication with the CORS station is missed or disconnected. Finally, in case the issues to use RTK or VRS due to communication problems specially the regions within mountains areas such as MAKKAH in this situation the GPS kinematic on the fly technique is highly recommended to replace the stop-go and kinematic techniques, in all the surveying works of medium scale. Also, the distance between the surveyed point and the reference receiver does not affect the resulted coordinates for about 7 km.

This expereament was carried out in plant tissue culture laboratory of the Horticulture Department, Faculty of Agriculture, University of Duhok, Iraq, during 2014, using two types of explants (Shoot tips and nod segments) in the establishment stage. The highest percentage of shoot /explant (100%) was obtained from Stockton Morello rootstock on both media, while 96.88% was recorded with WPM (Woody plant medium) from nodal segment in F12/1 Mazzard and (87.5%) was observed from shoot tip in Mohaleb. While the highest shoot number with three rootstocks (24.50, 24.38 and 22.25 shoot /explant) with Stockton Morello, F12/1 Mazzard and Mahaleb respectively, were recorded from nodal segment with WPM. While the lowest number of shoots (19.63 shoots /explant) was formed when the shoot tips were cultured on MS medium. At the multiplication stage, the maximum number of shoot per explant (9.50 and 9.17 shoots /explant) in Stockton Morello rootstock was recorded with WPM and MS medium provided with 3mg l-1 BA. The interaction of Stockton Morello with WPM and MS medium having 1.5 mg l-1 BA produced an average of shoot length (3.58 and 3.52 cm) and the increased of shoot length was significantly compared with all treatment without the treatment in combination of Stockton Morello rootstock in WPM medium supplemented with 3 mg l-1 BA. Also the highest length of shoot per explant with three rootstocks 3.58 and 2.98 cm in Stockton Morello and F12/1 Maazard were recorded in WPM having 1.5mg l-1 BA and in Mahaleb rootstock (2.92 cm) was recorded on MS medium containing 1.5mg l-1 BA.
Da ALCA à CELAC: o Brasil e os desafios da integração continental / CELAC the FTAA: Brazil and the challenges of continental integration

Published: July 2020

Este trabalho procura, primeiramente, analisar o processo de negociações da Área de Livre Comércio das Américas (Alca), que reuniria 34 países do continente americano, ou seja, todos que o compõem, à exceção de Cuba. Busca-se também examinar os desdobramentos diretos e indiretos das negociações, pois se infere que o impacto desse projeto sobre as relações entre os EUA e os países da América Latina e Caribe, e entre os próprios países latino-americanos, foi muito significativo. A proposta foi lançada na I Cúpula das Américas, em 1994, por iniciativa dos EUA, e tinha o encerramento de suas negociações previsto para 2005. Embora não tenha sido implementada, a negociação da Alca produziu efeitos, contrabalançando processos de integração latino-americanos. A corroboração do fracasso da proposta da Alca, em 2005, em Mar del Plata, sublinhou a importância dos processos próprios de integração e concertação política sul e latino-americanos. Esse acontecimento é relevante, pois tais processos se configuram como vias para o desenvolvimento e a defesa dos interesses nacionais dos países da região. A análise deste artigo parte das negociações da Alca durante o governo de Fernando Henrique Cardoso, examina a proposta de "Alca light" do governo Lula, e culmina na derrocada do projeto da Alca, nas iniciativas latino-americanas autônomas - como a CALC e a CELAC - e na nova estratégia dos EUA para a região.   Abstract: Firstly, this paper seeks to analyze the Free Trade Area of ??the Americas (FTAA) negotiation process, which would bring together 34 countries in the Americas, that is, all who compose it, except for Cuba. We also examine the direct and indirect consequences of negotiations, because the impact of this project on relations between the U.S. and Latin America and the Caribbean, and also among Latin American countries, was very significant. The proposal was launched at the 1st Summit of the Americas in 1994, as a U.S. initiative, and the closure of negotiations was scheduled for 2005. Although it has not been implemented, the FTAA has produced effects, counterbalancing processes of Latin American integration. The corroboration of the failure of the proposed FTAA, in 2005, in Mar del Plata, stressed the importance of the development of Latin and South America's own processes of integration and political coordination. This event is relevant, since such processes constitute ways for the development and defense of national interests of the countries in the region. This paper's analysis departs from the negotiations during the Cardoso government, examines the Lula administration proposal of a "light FTAA", and culminates with the collapse of the FTAA project, with autonomous Latin American initiatives - such as CALC and CELAC - and with the new U.S. strategy for the region.

Variaciones δ13C y δ15N en huemul (Hippocamelus bisulcus) durante el Holoceno en Cerro Casa de Piedra, Santa Cruz, Argentina. Implicancias para el estudio de su distribución pasada
Authors: Tessone Augusto , Fernández Pablo , Fernández Natalia , De Nigris Mariana
Published: July 2020

El objetivo de este trabajo es estudiar la evolución de los valores δ13C y δ15N de huemul a lo largo del Holoceno en la localidad arqueológica Cerro Casa de Piedra (CCP), ubicada en la provincia de Santa Cruz. Asimismo, busca determinar la profundidad temporal de las actuales diferencias isotópicas entre huemules y guanacos de esta zona, asociadas al uso del bosque y la estepa respectivamente. De esta manera, se pone en discusión la antigua distribución del huemul y la hipótesis de una retracción de la especie al bosque. Se analizaron 20 fragmentos óseos de huemul y 18 de guanaco agrupados en Holoceno temprano (10.000-8000 años AP), medio (8000-4000 años AP) y tardío (4000-presente años AP). El huemul registró una media de δ13C -20,9‰ ± 0,7‰ y de δ15N 1,3‰ ± 1‰. El δ13C y el δ15N de huemul no exhiben variaciones significativas durante el Holoceno y no se diferencian de los especímenes modernos de la especie. Esta ausencia de variación permite asociar al huemul con zonas de bosque o ecotonales en esta región de Patagonia meridional durante todo el Holoceno, lo cual resta sustento a la hipótesis del uso de ambientes esteparios por parte de este cérvido en el pasado.
Territorialidades y desigualdades de orientación: los espacios entre estos dos conceptos y sus interrelaciones. (Reflexiones a partir del caso de Francia)
Authors: Champollion Pierre , Balduzzi Matilde
Published: July 2020

Salvo en los últimos años –e incluso muy raramente–las relaciones entre territorialidades, o territorios simbólicos y desigualdades específicas de orientación han sido escasamente estudiadas. La literatura en la materia, en lengua francesa, portuguesa y española, concerniente específicamente a esta compleja cuestión reúne hoy solo algunos pocos artículos científicos, a veces generales (Champollion, 2015), a veces vinculados a un contexto territorial particular, como sucede con la zona de montaña (Champollion, 2019). La primera parte de este artículo abordará la diferenciación progresiva de la noción de desigualdad educativa que, actualmente, aparece cada vez más como multifactorial (contextual, escolar en términos de rendimiento, de orientación, etc.). La segunda parte tratará sobre la diferenciación progresiva de las diferentes dimensiones de la noción de territorio –en particular, institucional, vivido, simbólico, interiorizado– que ha visto surgir hacia fines del siglo XX, la territorialidad. La tercera parte, finalmente, una vez trazado este cuadro conceptual, se centrará en el impacto de la territorialidad sobre la orientación escolar y profesional de los alumnos.
Remote instruction and distance education: A response to COVID-19
Authors: Lindner James , Clemons Christopher , Thoron Andrew , Lindner Nicholas
Published: July 2020

The purpose of the qualitative study was to explore how middle and secondary school agriscience teachers define remote instruction and distance education. This research was conducted as a response to the COVID-19 pandemic. Data for the study were collected during the time schools were closed and/or offering remote instruction. A purposive sample of seventeen agriscience education teachers in the States of Alabama and Georgia were selected for this qualitative study. Data were collected using a structured interview questionnaire and analyzed using constant comparisons. The conceptual framework of this study was developed using transactional distance theory and bound by strategic analysis. Findings showed that secondary agriscience education teachers did not collectively define remote instruction and distance education in the same manner. Some defined them similarly, and some noted specific differences in how the terms are defined and used. These teachers identified strengths and opportunities that should be exploited and weaknesses and threats that should be mitigated. Recommendations for training in appropriate use of distance education delivery strategies are provided. Recommendations for additional research into the impact on student learning are provided.

Dynamical Masses for the Pleiades Binary System HII-2147
Authors: Torres Guillermo , Melis Carl , Kraus Adam L. , Dupuy Trent J. , Chilcote Jeffrey K. , Crepp Justin R.
Published: July 2020

We report our long-term spectroscopic monitoring of the Pleiades member HII-2147, which was previously spatially resolved at radio wavelengths in very long baseline interferometry (VLBI) observations. It has also been claimed to be a (presumably short-period) double-lined spectroscopic binary with relatively sharp lines, although no orbit has ever been published. Examination of our new spectroscopic material and the historical radial velocities shows that the current and previous spectra are best interpreted as featuring only a single set of lines of a moderately rapidly rotating star with slowly variable radial velocity, which is one of the sources detected by VLBI. We combine our own and other velocities with the VLBI measurements and new adaptive optics observations to derive the first astrometric-spectroscopic orbit of the G5 + G9 pair, with a period of 18.18 ± 0.11 yr. We infer dynamical masses of 0.897 ± 0.022 M
☉ for the spectroscopically visible star and 0.978 ± 0.024 M
☉ for the other, along with a distance of

pc. The lack of detection of the lines of the more massive component in our spectra can be adequately explained if it is rotating much more rapidly than the star we see. This is consistent with the observation that the lines of the secondary are shallower than expected for a star of its spectral type.

We present submillimeter spectra of the (proto-)super star cluster (SSC) candidates in the starbursting center of the nearby galaxy NGC 253 identified by Leroy et al. The 2.5 pc resolution of our Atacama Large Millimeter/submillimeter Array cycle 3 observations approaches the size of the SSCs and allows for the study of physical and chemical properties of the molecular gas in these sources. In the 14 SSC sources and in the frequency ranges 342.0–345.8 GHz and 353.9–357.7 GHz, we detect 55 lines belonging to 19 different chemical species. The SSCs differ significantly in chemical complexity, with the richest clusters showing 19 species and the least complex showing four species. We detect HCN isotopologues and isomers (H13CN, HC15N, H15NC), abundant HC3N, SO and S18O, SO2, and H2CS. The gas ratios CO/HCN, CO/HCO+ are low, ∼1–10, implying high dense gas fractions in the SSCs. Line ratio analyses suggests chemistry consistent with photon-dominated regions and mechanical heating. None of the SSCs near the galaxy center show line ratios that imply an X-ray-dominated region, suggesting that heating by any (still unknown) active galactic nucleus does not play a major role. The gas temperatures are high in most sources, with an average rotational temperature of ∼130 K in SO2. The widespread existence of vibrationally excited HCN and HC3N transitions implies strong infrared radiation fields, potentially trapped by a greenhouse effect due to high continuum opacities.

Published: July 2020

Begonia is a mega-genus with about 2500 species by most estimates, with China having over 210 accepted species. After field surveys, literature review and examination of herbarium specimens, some new taxa, new records, synonyms and the hybrid-origin of some taxa have been confirmed. Here, we report that Begonia dioica Buch.-Ham. ex D.Don and B. flagellaris Hara, both from Xizang (Tibet) are new to China; Begonia lipingensis Hance, B. muliensis T.T.Yu and B. sizemoreae Kiew are synonyms of B. circumlobata Hance, B. taliensis Gagnepain and B. longiciliata C.Y.Wu, respectively; and Begonia × lancangensis S.H.Huang and B. × malipoensis S.H.Huang & Y.M.Shui are natural hybrids.

Published: July 2020

Aristolochia yachangensis B.G.Huang, Yan Liu & Y.S.Huang, a new species from limestone areas in Guangxi, China, is described and illustrated. It is morphologically most similar to A. fangchi Y.C.Wu ex L.D.Chow & S.M.Hwang, A. petelotii O.C. Schmidt and A. championii Merr. & Chun in shape of leaf blade, anther, gynostemium and inflorescence on old woody stems. However, it can be easily distinguished from the latter by shape of inflorescence, length of upper and lower portions of perianth tube, colour of the limb and throat. A table and a key to distinguish the new species from other morphologically similar Aristolochia species are also provided.
Arthrogryposis Multiplex Congenita
Authors: Langston Seth , Chu Alison
Published: July 2020

Arthrogryposis multiplex congenita (AMC) is a complex, etiologically diverse, clinical descriptor identified in a variety of diagnoses characterized by multiple congenital joint contractures. The root cause of AMC is decreased fetal movement in-utero, whether resulting from maternal or pregnancy influences, nervous system pathology, or an underlying genetic abnormality. Prenatal diagnosis via ultrasonography can be challenging and may require additional imaging techniques or studies. After birth, these infants may require assistance breathing and feeding depending on the underlying diagnosis. Physical therapy and surgical intervention of the contractures are the mainstays of therapy, and outcomes can be good when intervention is provided in a timely manner. Those infants with syndromic causes of arthrogryposis are more likely to have poor outcomes; therefore, determining the underlying etiology for AMC is important as this can influence counseling regarding individual prognosis as well as future pregnancies.

Household risk‐sharing channels
Authors: Asdrubali Pierfederico , Tedeschi Simone , Ventura Luigi
Published: July 2020

This paper aims to fill the gaps in the analysis of risk‐sharing channels at the microlevel, both within and across households. Using data from the Bank of Italy's Survey on Household Income and Wealth covering the financial crisis, we are able to quantify in a unified and consistent framework several risk‐sharing mechanisms that so far have been documented separately. We find that Italian households were able to smooth on average about 85% of shocks to household head's earnings in both 2008–2010 and 2010–2012 spells. The most important smoothing mechanisms turn out to be self‐insurance through savings/dissavings (40% and 47% in 2008–2010 and 2010–2012, respectively), and within‐household risk‐sharing (16% and 14%). Interestingly, risk‐sharing through portfolio diversification and private transfers is rather limited, but the overall percentage of shock absorption occurring through private risk‐sharing channels hovers around four‐fifths, as opposed to around one‐fifth of a shock cushioned by taxes and public transfers, excluding pensions. In addition, by exploiting subjective expectations on the following year's household income, we find significant evidence of a lower degree of smoothing of persistent shocks.
Asymmetric information in secondary insurance markets: Evidence from the life settlements market
Authors: Bauer Daniel , Russ Jochen , Zhu Nan
Published: July 2020

We use data from a large US life expectancy provider to test for asymmetric information in the secondary life insurance—or
life settlements—market. We compare realized lifetimes for a subsample of settled policies relative to all (settled and nonsettled) policies, and find a positive settlement‐survival correlation indicating the existence of informational asymmetry between policyholders and investors. Estimates of the “excess hazard” associated with settling show the effect is temporary and wears off over approximately 8 years. This indicates individuals in our sample possess private information with regards to their near‐term survival prospects and make use of it, which has economic consequences for this market and beyond.
Houthis in the Making: Nostalgia, Populism, and the Politicization of Hashemite Descent
Authors: Nevola Luca
Published: July 2020

During the autumn of 2012 the Hashemites (sāda) of a hijra I will call Kuthra, located southwest of the capital Sanaa, gradually rephrased their identity in political terms. Over the course of one year, most of them turned into Houthi supporters, prompting an equal and opposite reaction in the Qaḥṭānī Arabs of the village that defiantly adhered to the Islah party. Drawing on extended fieldwork in highland Yemen (2009–2013), this paper tackles identity politics by examining the subtle interplay of life and family stories, modes of livelihood and social institutions in a ‘glocal’ world.By exploring the family stories of two young sāda, the article argues that the rapid and unprecedented social and material changes that interested Kuthra during the last century laid the groundwork for nostalgic representations of a lost past. Building on this emotional foundation, Houthi discourse provided a political narrative capable of orchestrating nostalgic feelings into a coherent life project, thus providing a powerful tool for identity politics.
Les frères al‑Sirājī et les frères Maḥfūẓ : des relieurs à cheval entre un savoir hérité et la demande du marché
Authors: Rubino Marcella
Published: July 2020

Cet article est le résultat d’une enquête de terrain réalisée au Yémen entre 2003 et 2004 sur les artisans relieurs. Il s’agit d’une analyse à la fois technique, sociologique et linguistique sur un métier artisanal qui, au début des années 2000, était déjà en forte transformation et dont on ne connait pas l’évolution aujourd’hui à cause de l’inaccessibilité du terrain yéménite pour les chercheurs étrangers. Cette étude se veut donc un état des lieux de la situation —au début du xxie siècle— d’un métier qui a subi d’une part les conséquences de l’industrialisation du secteur du livre et des progrès de la technique, et d’autre part des changements économiques successifs. Ainsi, à travers une étude de cas sur deux familles de relieurs « de père en fils », cet article s’interroge sur la part du savoir hérité dans les pratiques des relieurs, dans une optique de sauvegarde d’un patrimoine immatériel amené, comme d’autres métiers artisanaux, à disparaitre.
L’éducation de Nietzsche. Réactualisation des considérations sur l’honneur : une des valeurs de l’ethos universitaire
Authors: Marty Olivier
Published: July 2020

Nietzsche est un philosophe de l’éducation qui s’insère dans la tradition de l’apprentissage tout au long de la vie européenne : revivifiant les joutes homériques, il redonne un sens éducatif à la valeur de l’honneur – honneur que nous prenons comme matériau philosophique pour étayer l’herméneutique scientifique de son œuvre de jeunesse. En posant Nietzsche comme un apprenant avant d’être un éducateur, nous faisons avec lui une généalogie de la valeur morale de l’honneur et voyons comment ce fait anthropologique est une constante de l’éducation dans notre civilisation. L’honneur apparaît en particulier comme un ethos scientifique et le centre autour de quoi gravitent les universitaires. En relisant comment Nietzsche a appris, les éducateurs et les universités peuvent apprendre de Nietzsche à utiliser les honneurs afin de croître et se développer. L’honneur prévaut en tant que monument du passé pouvant instruire les futurs grands hommes. Heidegger aura une lecture esthétique de cet art où il faut apprendre à se surmonter.
Ce qu’apportent les interactions verbales à l’acquisition de l’orthographe grammaticale
Authors: Cogis Danièle
Published: July 2020

On explique généralement les erreurs persistantes des élèves en orthographe par un défaut d’application des règles. Mais, dès les années 1990, des recherches faisant appel à la méthodologie des entretiens métagraphiques ont montré que les processus d’acquisition reposent sur une conceptualisation progressive des notions grammaticales. Il importe alors de travailler le décalage entre les élaborations conceptuelles des élèves confrontés à un système orthographique très complexe et les paramètres qui régissent les fonctionnements linguistiques. L’article s’intéresse aux rapports entre verbalisation et conceptualisation à l’occasion d’un entretien avec deux élèves de CM1 (4e année de primaire) et éclaire le cheminement qui les a menés à la « découverte » des participes passés employés comme adjectifs.
Les émotions au service de la métamorphose identitaire des professeurs stagiaires d’anglais de l’académie de Créteil
Authors: Lemarchand-Chauvin Marie-Claire
Published: July 2020

L’année de formation initiale des enseignants stagiaires est riche en émotions (Lemarchand-Chauvin & Tardieu, 2018) et leur position transitoire entre deux temps, à moitié étudiant et à moitié enseignant, la rend parfois douloureuse et difficile. Durant cette période de transition – qui n’est pas sans rappeler la crise identitaire de l’adolescent – le stagiaire va progressivement enclencher la construction de son identité professionnelle. Cette étude s’appuie sur deux cohortes de professeurs stagiaires d’anglais de l’académie de Créteil. Elle repose sur l’hypothèse qu’il est possible d’accompagner les professeurs stagiaires dans leur métamorphose en leur permettant de partager leurs émotions (Rimé, 2005) avec leurs pairs par le biais de groupes de parole libre favorisant l’écoute empathique, de modules engageant le corps et la voix (Pujade-Renaud, 1984 ; Tellier & Cadet, 2014) et des sessions de théâtre forum. Placer les émotions et l’empathie au cœur de la formation initiale permettrait d’accéder plus facilement à la réflexivité (Schön, 1983, 1987) et à la croissance professionnelle ou métamorphose des enseignants débutants.
