Il s’agit d’observer à travers une enquête menée auprès de deux catégories d’individus français destinées à devenir enseignant à l’école primaire (n = 223), quels aménagements de classe sont perçus comme propices à un climat d’apprentissage optimal ? Autrement dit, quelles composantes du climat d’apprentissage influent sur leurs représentations de la classe idéale et existe-t-il des points de vue divergents selon le profil des deux publics ciblés (étudiants et enseignants stagiaires) et entre celles et ceux qui exercent en maternelle et en élémentaire ? Les classements obtenus à partir de la procédure originale de Condorcet et de la méthode de Borda dévoilent en premier lieu l’appétence des répondants pour l’organisation en îlots et en classe flexible. En second lieu, la classe en autobus serait ressentie comme plus propice à la gestion de classe qu’au bien-être des élèves et à leurs apprentissages. Au final, en différenciant les dispositifs spatiaux selon les objectifs visés (gestion de classe, apprentissages, bien-être), les étudiants et fonctionnaires stagiaires aborderaient la salle de classe comme un levier façonnant le comportement des élèves et leur engagement dans les apprentissages.
Taalangst in het klaslokaal: De taalangstniveaus van Hongaarse studenten Neerlandistiek
Authors: Gőcze Borbála
Published: April 2022

Het doel van het onderzoek dat in dit artikel wordt beschreven, was om een beeld te krijgen van de taalangstniveaus van de studenten Neerlandistiek die aan de drie Hongaarse universiteiten studeren (Universiteit Debrecen, Eötvös Loránd Universiteit, Károli Gáspár Universiteit van de Gereformeerde Kerk).

Hoe verschillen de angstniveaus van studenten Neerlandistiek van de verschillende studiejaren aan de drie Hongaarse universiteiten? Met behulp van een enquêteonderzoek toetste ik de verschillen tussen de angstniveaus van de studenten in de context van het klaslokaal.

De resultaten van het onderzoek laten zien dat de bachelorstudenten (vooral de eerstejaarsstudenten) hogere niveaus van angst ervaren dan de masterstudenten. Dit suggereert dat het niveau van taalkennis een invloed heeft op het niveau van taalangst.
Borylated norbornadiene derivatives: Synthesis and application in Pd-catalyzed Suzuki–Miyaura coupling reactions
Authors: Schulte Robin , Ihmels Heiko
Published: April 2022

The photochromic norbornadiene/quadricyclane system is among the most promising candidates for molecular solar thermal (MOST) energy storage. As in this context there is still the need for new tailor-made derivatives, borylated norbornadienes were synthesized that may be used as versatile building blocks. Thus, the 4,4,5,5-tetramethyl-2-(bicyclo[2.2.1]heptadien-2-yl)-1,3,2-dioxaborolane was prepared and shown to be a suitable substrate for Pd-catalyzed Suzuki–Miyaura coupling reactions with selected haloarenes. It was demonstrated exemplarily that the novel monosubstituted 2-(1-naphthyl)norbornadiene, that is accessible through this route, is transformed to the corresponding quadricyclane upon irradiation, whereas the back reaction can be accomplished by thermal treatment.
Revalorización de terrenos agropecuarios a través de proyectos de restauración: estudio de tres casos
Authors: Moreno Medina Marisela , Martín del Campo Saray Francisco José
Published: April 2022

El estudio que se presenta muestra la importancia de la restauración de suelos a través de la valuación, desde la última década del siglo XX la valoración agraria ha cobrado mayor relevancia, conceptos como el paisaje, los servicios ambientales y la conservación se han hecho presentes como bienes intangibles y esto brinda un nuevo sentido a los trabajos valuatorios. El objetivo de la investigación fue fundamentar el valor de la restauración de suelos en terrenos rurales y/o agropecuarios, para lo cual se consideraron tres predios agropecuarios que antes de ser sometidos a un proceso de restauración integral se realizó un avalúo comercial, una vez concluidos los trabajos de restauración y pasados cinco años, se actualiza el avaluó comercial, encontrando que, si bien la inversión que se hizo para llevar a cabo el proceso de restauración se puede recuperar con los resultados obtenidos, este tipo de trabajos no representa grandes márgenes de utilidad, lo que muestra la importancia de cuidar la degradación de las tierras.

Authors: Chetan Kumar G.K. , Rangappa K.B. , S Suchitra
Published: April 2022

Entire global economy has been adversely affected by the demand and supply shocks which have been created due to consequent waves of Covid-19 pandemic. Indian Economy was none the better amidst the second wave. Due to the demand and supply shocks at both national and international level, Indian Economy witnessed an unprecedented contraction of its Gross Domestic Product by around twenty four percent. In this context one of the few prominent sectors which could assist in the recovery of Indian Economy is expected to be Real Estate. Due to its inherent forward and backward linkages with infrastructure, it could assist in faster recovery of economy through multiplier effect. In addition to that, Credit Policy is going to play a vital role in assisting the recovery of any prominent sector. In this backdrop, our study is an attempt to analyze as to whether Real Estate, Infrastructure and Financial sector are co-integrated or not. Further, provided they are co-integrated, our study tries to find out the speed of correction. Our paper through its empirical approach aims to suggest relevant credit policy measures.

Dihydropyrimidinones and thiones are a significant class of organic as well as heterocyclic compounds synthesized by cyclo condensation reaction, called Biginelli reaction that was reported for the first time by Italian chemist Pietro Biginelli in 1893. The synthesis of dihydropyrimidinones and thiones involve one pot multicomponent reaction (MCR) of various aldehydes, β- ketoester and urea or thiourea. Now, the dihydropyrimidinones and thiones have emerged as one of the most advantaged medicinal pharmacophores as they appear as an important structural part in many naturally occurring and synthetically prepared medicinal drugs. It possesses wide spectrum of biological activities like antitubercular, Anti-malarial, anticancer, anti-HIV activity, analgesic, antiepileptic, CNS activity, anti-inflammatory, calcium and potassium channel blocker [2], antihypertensive agents [3], α-la-antagonist [4], antioxidants [6] and neuropeptide Y (NPY) antagonists.[7]

This prospective cross-sectional study was conducted to measure the contrast sensitivity in different types of glaucoma patients. The patients for this study were identified using a non-probability convenient sampling method from 01st February 2020 to 30th August 2020. The diagnosis and sensitivity were tested using lea contrast sensitivity, Snellen visual acuity charts, trial box, and occluder. The data were analyzed using Statistical Package for Social Sciences (SPSS version 20.0). Out of 60 patients, including 37 males and 23 females, between 16-80 years of age. 33 (55 %) patients were diagnosed with Primary Open Angle Glaucoma(POAG), 17 (28.3 %) patients with Primary Close Angle Glaucoma, 7 (11.7%) patients with Acute Closure Glaucoma(PCAG), and 3 (5%) patients with Secondary Glaucoma. Similarly, with glasses, 46 (76.7 %) patients had visual acuity 6/6 to 6/12, 11 (81.3%) patients had 6/18 to 6/36 and 3 (5 %) patients had 6/60. According to contrast sensitivity 30 (50%) patients had 1.25% (80%), 21 had 2.50% (40%) and 9 had 5% (20%). 15 subjects had 1.25% (80%), 13 subjects had 2.5 %( 40%) and 5 subjects had 5% contrast sensitivity in POAG. Around 11 subjects had 1.25% (80%), 4 subjects had 2.5 % (40) and 2 subjects had 5% contrast sensitivity in PCAG, 3 subjects had 1.25% (80%), 3 subjects had 2.5 % (40) and 2 subjects had 5% contrast sensitivity in PCAG. There was a reduction in contrast visual acuity with and without refraction. Most of the patients had variation at the level of Contrast Visual Acuity in POAG.
Awareness of mothers regarding use of natural probiotics in school going healthy children's diet
Authors: Shah Fasiha , Shah Nabia , Shah Faisal Hyder
Published: April 2022

Probiotics are recently getting popular as immunity enhancers, and being investigated to treat acute infections, including gastroenteritis. Commonly used probiotics have been in practice for ancient periods. This study was thus conducted to evaluate the knowledge of mothers of school-going children regarding the use of probiotics in their children's diet. Our results showed that 23% of women were aware of probiotics and their health benefits out of 200 women surveyed, while 16% had never heard of probiotics. However great majority were taking probiotic-rich food, including yogurt, buttermilk, and cheese, in their diet. The knowledge of the use of probiotics in mothers was significantly associated with mothers' level of education. We conclude that there is limited knowledge of probiotics and their health benefits in mothers, but given the anecdotal evidence and inherited dietary patterns, probiotics are part of the daily diet of the school-going children in our study population.

Georges Martin, un fonctionnaire ordinaire de l’administration coloniale française à Lyon (1940-1960)
Authors: Belmessous Fatiha
Published: April 2022

Cet article entend participer aux débats sur le fait colonial et ses rémanences à partir du suivi de la trajectoire professionnelle de Georges Martin (administrateur civil ordinaire) durant une séquence historique charnière (les années 1940-1960). Cet acteur a travaillé exclusivement à Lyon en tant que fonctionnaire au sein de la préfecture du Rhône (SAMAS) puis comme directeur d’un organisme de logements sociaux majeur au sein de l’agglomération lyonnaise (Logirel). La mise en scène de ses pratiques bureaucratiques quotidiennes illustre la manière dont le projet politique colonial s’est incarné. Cette micro-histoire est mise en lumière à travers une enquête archivistique mêlant documents personnels et documents institutionnels dépouillés aux archives du département du Rhône et de la métropole.
Insécurité et (re)négociation des frontières ethno-raciales
Authors: Chuang Ya-Han , Merle Aurore
Published: April 2022

Cet article analyse les mobilisations d’habitants chinois dans des quartiers populaires de Seine-Saint-Denis autour des enjeux de sécurité des personnes dans l’espace public, dans un contexte d’agressions violentes subies par les populations d’origine asiatique. Ces actions collectives constituent un objet privilégié pour observer différents processus de racialisation à l’œuvre, qu’ils émanent des pouvoirs publics ou de différents groupes de population. Notre recherche de terrain montre que les configurations locales à l’échelle du quartier et les cadres de négociation avec les pouvoirs publics font une différence dans les relations intercommunautaires. Si les mobilisations sécuritaires des populations chinoises semblent contribuer initialement à renforcer les frontières ethno-raciales entre différents groupes d’habitants et à construire un problème public « racial-sécuritaire », les négociations avec les pouvoirs publics et les interactions avec d’autres acteurs associatifs montrent les potentialités de transformation et d’élargissement de luttes ancrées dans les quartiers, recomposant ainsi les frontières ethno-raciales.
Racialiser les locataires
Authors: Arnoulet Violette , Tournon Mariana
Published: April 2022

Au tournant des années 1980, des administrations locales impliquées dans ce qui deviendra la politique de la ville sont amenées à fabriquer des catégories raciales pour désigner et maîtriser la composition sociale de certaines cités HLM (habitation à loyer modéré). À partir de deux enquêtes socio-historiques menées en région parisienne et mobilisant des fonds d’archives de différentes natures, ainsi que des entretiens avec d’anciens responsables locaux, l’article analyse les conditions et les modalités d’apparition de ce langage. En amont des discriminations que ces catégories ont pu induire, le propos met en lumière le rôle peu étudié de responsables municipaux et de directions d’organismes HLM dans l’émergence d’un sens commun qui rend possible le classement des locataires en groupes, fondés sur une origine essentialisée. Malgré les variations observées dans les entreprises de catégorisation, ces dernières participent néanmoins à la fixation d’un système de classement racialisant et hiérarchisé.
Sous la mixité sociale, la race

Published: April 2022

À partir d’une enquête collective menée entre 2017 et 2020 sur les recompositions des politiques d’attribution et de peuplement dans six agglomérations françaises, cet article examine les processus de catégorisation à l’œuvre dans les politiques locales du logement social. Nous montrons d’abord qu’en dépit de la clarification du principe de mixité sociale et de la redistribution des rôles opérées par la loi Égalité et Citoyenneté de 2017, la majorité des acteurs locaux continue de mobiliser les catégories ethnoraciales antérieures. Les référents ethnoraciaux occupent toujours une place saillante dans les représentations sociales des acteurs et la manière dont ils perçoivent les situations d’attribution. Nous mettons ensuite en évidence des processus d’ethnicisation et de racialisation discrètes, construits sur des critères perçus comme plus légitimes que les critères manifestement ethniques ou raciaux. Enfin, nous analysons les conditions sociales qui rendent possible le maintien des catégories ethnoraciales par-delà la loi Égalité et Citoyenneté.
Naître déjà fille ou garçon
Authors: Larrieu Gaëlle
Published: April 2022

Alors que jusqu’aux années 1980, la question du sexe d’un enfant ne se posait qu’au moment de l’accouchement, actuellement, en France, 9 couples sur 10 connaissent le sexe de leur futur enfant avant sa naissance en raison de la généralisation des échographies fœtales. À travers une enquête par entretiens longitudinaux et observations, l’article montre comment la sexuation du fœtus est imbriquée dans le processus d’humanisation. Le classement par sexe du fœtus apparaît comme central : en effet, penser son enfant comme un être sexué permet de le nommer, de se projeter et d’interagir avec lui. En se centrant sur la sexuation et non sur la bicatégorisation et la socialisation différenciée, l’article permet d’enrichir la compréhension de la prégnance du genre dans notre société.
A comprehensive survey of zero-shot image classification: methods, implementation, and fair evaluation
Authors: Yang Guanyu , Ye Zihan , Zhang Rui , Huang Kaizhu
Published: April 2022

Deep learning methods may decline in their performance when the number of labelled training samples is limited, in a scenario known as few-shot learning. The methods may even degrade the accuracy in classifying instances of classes that have not been seen previously, called zero-shot learning. While the classification results achieved by the zero-shot learning methods are steadily improved, different problem settings, and diverse experimental setups have emerged. It becomes difficult to measure fairly the effectiveness of each proposed method, thus hindering further research in the field. In this article, a comprehensive survey is given on the methodology, implementation, and fair evaluations for practical and applied computing facets on the recent progress of zero-shot learning.
Nonlinear evolution of two vortex sheets moving separately in uniform shear flows with opposite direction
Authors: Matsuoka Chihiro
Published: April 2022

It has been considered that two close vortex sheets become unstable and evolve simultaneously when sufficiently strong uniform shears exist. However, Moore (Mathematika, 1976) suggested in his linear analysis that a vortex sheet evolves just as if the other vortex sheet were absent under certain conditions. In the current study, we investigate how the two vortex sheets evolve in the nonlinear region when they satisfy Moore's condition. We also consider density stratification, which is not included in Moore's analysis. Moore's estimate is only valid within linear theory; however, a motion suggested by Moore appears even in the nonlinear regime when Moore's condition is satisfied. We found that there is a case that a vortex sheet hardly deforms, even though the other sheet becomes unstable and largely deforms. We also show that there is a case that Moore's analysis is not effective even the condition is satisfied when a density instability exists in the system.

The fundamental purpose of this research is to investigate the existence theory as well as the uniqueness of solutions to a coupled system of fractional order differential equations with Caputo derivatives. In this regard, we utilize the definition and properties of a newly developed conception of complex valued fuzzy rectangular $ b $-metric spaces to explore the fuzzy form of some significant fixed point and coupled fixed point results. We further present certain examples and a core lemma in the case of complex valued fuzzy rectangular $ b $-metric spaces.
Configurations of external SME characteristics to explain differences in innovation performance
Authors: Pullen Annemien , de Weerd-Nederhof Petra , Groen Aard , Fisscher Olaf
Published: April 2022

As SMEs need to focus on core competences for efficiency matters, they need to cooperate with external partners to compensate for other competences and resources. This is especially the case in the field of new product development, where SMEs face specific problems compared to large firms. Recognizing the increasing importance of collaboration, the question remains how to organize these external networks. The research is based in the social systems perspective and systematically builds a research framework for the description and analysis of the organization of new product development in networks from the point of view of the SME. Furthermore the research framework not only elaborates on the individual external SME characteristics as past research did, but it identifies combinations of external firm characteristics that are hypothesized to improve the overall innovation performance. The paper results in the central research question of “how to organize the interaction between actors (organizations) in order to successfully shift from the exploration stage (development) to the exploitation stage (commercialization) to achieve high innovation performance”. In addition several testable hypotheses are constructed from theory.
Enterprise education and the adoption of newer technologies within small firms
Authors: Jones-Evans D. , Thompson P. , Kwong C.
Published: April 2022

Enterprise education has been regularly cited as a tool which can be utilised to not only increase the level of entrepreneurship within an economy, but also the success of those enterprises started. This paper explores the extent to which participation in enterprise education is associated with the adoption of new technology within new businesses. As this is one way that businesses can remain competitive not only within their own countries but when competing against international competition. Using data from the Global Entrepreneurship Monitor survey from the UK, the study finds weak evidence that those undertaking enterprise education in the form of university based schemes or government sponsored training schemes are more likely to be using newer technology. However, this relationship is relatively weak and does bring into question whether many enterprise courses are effective value for money.
The Web 2.0 as marketing tool: Opportunities for SMEs
Authors: Constantinides Efthymios
Published: April 2022

The new generation of Internet applications widely known as Social Media or Web 2.0 offers corporations a whole range of opportunities for improving their marketing efficiency and internal operations. Web 2.0 applications have already become part of the daily life of an increasing number of consumers who regard them as prime channels of communication, information exchange, sharing of expertise, dissemination of individual creativity and entertainment. Web logs, podcasts, online forums and social networks are rapidly becoming major sources of customer information and influence while the effectiveness of traditional mass media is rapidly decreasing. Using the social media as a marketing tool is an issue attracting increasing attention. The hitherto experience is that large public corporations are more likely to make use of such instruments as part of their marketing and internal operations (McKinsey, 2007).The paper defines the Web 2.0 phenomenon and based on the experience of large corporations examines how SMEs could engage the various Web 2.0 instruments in order to efficiently market their products, improve customer relations, increase customer retention and enhance internal operations.
A multidimensional decision-making model for internationalization of high-tech SMEs in transition economics
Authors: Roersen M.J. , Groen A.J. , Kraaijenbrink J.
Published: April 2022

Until now, international entrepreneurship has mainly used stage theory, institutional theory, transaction cost economics and the resource-based view to explain or describe the internationalization of SMEs in transition economy context. Following recent literature we contend that these approaches are highlighting interesting elements of decision processes for internationalization, but are not yet enough managerial applicable because of the unidimensionality of these theories. We provide a model in four steps which enables multidimensional analyses of internationalization processes. In this the strengths and weaknesses in the strategic, economic, cultural and social network capital of the focal firm are assessed. Shortcomings in these capitals can be complemented by their partners to increase chances of successful internationalization. This article is a deductive study on three innovative Russian high-tech SMEs. The first case illustrates a clear fit with a potential partner, the second case describes a poor fit and in the third case the firm would not benefit from internationalization.
Un petit peuple de pacotille : les faux groupes dits « d’Asie Mineure » dans les collections du musée du Louvre et du Metropolitan Museum of Art de New York
Authors: Livenais Arthur
Published: April 2022

Conséquence de la découverte de la nécropole de Tanagra au début des années 1870, la production de fausses terres cuites grecques est l’une des mystifications archéologiques les plus importantes de la fin du XIXe siècle. Jusqu’au début des années 1900, les fausses figurines se diffusent en masse au sein du marché de l’art, des musées et des collections privées. Parmi elles, les groupes dits « d’Asie Mineure » se distinguent par leur iconographie attrayante et leur style « baroque », fruits de l’érudition et de l’inventivité des faussaires. Le présent article propose de s’intéresser plus particulièrement à cet ensemble par le prisme des collections du musée Louvre et du Metropolitan Museum of Art de New York, en le resituant dans son contexte historique.

Archives vivantes est une série d’entretiens filmés réalisée au Sénégal et au Bénin entre 2011 et 2015 dans le cadre d’un projet de recherche porté par une équipe pluridisciplinaire de l’ENS de Lyon, Vivants objets. Au cours de ces entretiens, les photographies, le parcours et les fiches muséales d’objets du quotidien collectés par la mission Dakar-Djibouti (1931-1933) ont été soumis à des artistes, des professionnels de la culture, des usagers. « Archives vivantes » d’objets « ethnographiques » conservés dans des musées, ces films rendent palpable l’impact de leur disparition — transmission brisée, perte de savoirs —, et restituent une part de leur patrimoine immatériel, hic et nunc. Ils témoignent de l’intérêt suscité par ces objets auprès des sociétés qui les ont créés, de l’urgence d’un travail de réappropriation et interrogent les conditions de leur retour, ou de leur restitution.
Archiving ethnography? The impossibility and the necessity
Authors: Zeitlyn David
Published: April 2022

I review the conflicting injunctions to archive and not to archive anthropological field materials (data). There are ethical contradictions: some ethics codes tell us to destroy data after a period of time, others to save for the long term. I discuss the responsibilities researchers have to different groups of people and how these may conflict. I illustrate beneficial long-term uses of field data from my own work with Mambila people in Cameroon and Nigeria, partly using archival material in ways never originally intended (so never considered for consent). To adhere strictly to some data management protocols would result in inhumane and I suggest unethical action. We must accept that life is contradictory and find ways of managing this: long term embargoes might provide a solution that is workable, although difficult to implement with digital archives.

Après avoir présenté les contexte historique et touristique de Sabah en Malaisie, cet article propose une analyse de la mise en scène de l’ethnicité pour les touristes au sein du Sabah Village. Selon le profil socio-culturel des touristes, la visite peut être perçue comme : un renforcement du sentiment nationaliste, un renforcement d’un sentiment de supériorité et de la différence entre « nous » et « eux », ou encore comme une visite qui favorise une quête d'exotisme et de primitivisme. Ces différents types se rejoignent autour de l’aspect ludique des activités offertes.
De quelle éducation au politique l’évaluation PISA de la « compétence globale » est-elle porteuse ?
Authors: Charlier Jean-Émile , Croché Sarah
Published: April 2022

Adoptés solennellement par les 193 États membres de l’Organisation des Nations unies en septembre 2015, les Objectifs du développement durable (ODD) sont présentés comme « 17 objectifs pour sauver le monde » (United Nations 2015). Ils proposent à tous les pays, sans aucune exception, des réponses aux principaux défis qui se posent à l’humanité, parmi lesquels ceux qui sont « liés à la pauvreté, aux inégalités, au climat, à la dégradation de l’environnement, à la prospérité, à la paix et à la justice » (id.). En cela, ils portent un programme d’éducation au politique qui se lit de façon transversale dans toutes les cibles envisagées, mais qui apparaît de la façon la plus explicite dans certaines de celles qui concernent l’enseignement. Cet article se concentre sur celles qui sont focalisées sur l’éducation au développement durable, et plus précisément encore sur l’évaluation qu’en organise le programme PISA de l’OCDE en prenant la mesure de la « compétence globale ».
Soutenir la justice épistémique par la formation réciproque au cœur d’initiatives citoyennes de transition énergétique porteuse de justice sociale
Authors: Brière Laurence , Moreau Guillaume , Prud’homme Maude , Orellana Isabel , Marleau Marie-Ève , Chatelain Martine
Published: April 2022

Le mouvement écocitoyen pour une transition énergétique travaille à transformer le système économico-énergétique dominant dans une visée de justice sociale et de respect de l’environnement. En collaborant avec les acteurs et actrices de cette mobilisation dans le cadre d’une recherche-action, nous avons soulevé les enjeux de justice épistémique inhérents à ce projet politique. Nous avons aussi voulu créer des espaces de formation réciproque qui mettent en valeur la diversité des types de savoirs. Nous avons réfléchi aux besoins cruciaux et aux possibles vecteurs d’intensification de la collaboration et du partage de savoirs entre les différents groupes d’acteurs composant le mouvement : associations syndicales, groupes écologistes et communautaires, comités citoyens et milieux universitaires. Nous avons en outre proposé un cadre conceptuel innovant de la justice énergétique, qui prend en compte les réalités très concrètes des luttes et initiatives écocitoyennes
Penser éducation au politique et questions environnementales dans la démocratie
Authors: Roelens Camille
Published: April 2022

Ce texte confronte l’éducation au politique au révélateur que constituent les questions environnementales, du point de vue de la philosophie politique de l’éducation. Nous posons d’abord les jalons de ce que peut-être une épistémologie de l’éducation au politique dans la démocratie et ce que cette dernière permet ensuite en termes de travail intellectuel (1). Nous tâchons ensuite de voir comment ce modèle peut nous aider à penser l’autonomie humaine face aux questions environnementales (2). Se pose ensuite la question des lieux les plus adéquats pour penser l’éducation au politique face auxdites questions. Les domaines de l’expérience, de l’éducation informelle et du rapport individuel aux productions culturelles contemporaines apparaissent alors comme privilégiés. Une brève étude illustrative de la démarche et de l’œuvre du groupe de musique canadien Les Cowboys fringants (3), témoigne de la manière dont ce type d’éducateurs informels peut jouer un rôle important pour fournir des ressources à l’autonomie humaine et des propositions d’influences face aux questions environnementales dans le cadre politique démocratique.
Quels curricula d’éducation au politique dans les questions environnementales et de développement ?
Authors: Barthes Angela
Published: April 2022

Nous clarifions ce que nous entendons par éduquer au politique, puis ce qu’implique concrètement de construire des curricula intentionnels d’une telle éducation. Clarifier les épistémologies de savoirs politiquement situés, multiréférentialiser des rapports sociaux, problématiser et reconnaitre des rapports de pouvoir et d’injustice en sont quelques facettes. Nous proposons une lecture d’une histoire de l’éducation aux questions d’environnement et de développement et des ? courants successifs d’éducation relative à l’environnement, au développement durable et au temps de l’anthropocène dans une perspective de présence ou d’absence d’éducation au politique. Nous mettons également en évidence un changement de paradigme récent, faisant suite à deux décennies d’éducations au développement durable fortement inscrites dans le comportementalisme, vers des éducations au temps de l’anthropocène qui offrent davantage de potentialité de socialisation politique.
A Framework for Topic Evolution and Tracking Their Sentiments With Time
Authors: Pradhan Rahul , Sharma Dilip Kumar
Published: April 2022

With the ongoing covid-19 pandemic, people rely on online communication to remain connected as a precautionary measure to maintain social distancing. When we have no one on our side to listen and console us in state of fear and dilemma, we try to find comfort in anonymity of social media. Tracking real-time changes in sentiments are quite difficult as it could not correlate well with human understanding and emotions, which changes with time and many other factors. Collecting sentiments from users on search results, news articles, paintings, photographs are nowadays common. This is a more robust and effective method as traditional ways do not rely on a lot of retrospectives. In this paper, we will be analyzing the data collected from Twitter on Covid-19 and see topic modelling can be meant to detect sentiment analysis. The challenge is here we need to see results over time, and changes detect in topics and sentiments. We analyze our method over covid-19 data and farmer’s protest. Results from this experiment using the proposed methodology are promising and giving valuable insights.

Published: April 2022

Node localization process is a crucial prerequisite in the area of Wireless Sensor Networks (WSNs). The algorithms for node localization process can either range-based or range-free. Range-free algorithms are preferred over range-based ones due to their cost-effectiveness. DV-Hop along with its variants is normally well-liked range-free algorithm because of its straightforwardness, scalability and distributed nature, but it has some disadvantages such as poor accuracy and high-power utilization. To deal with these limitations, this paper introduces an algorithm, called GWOGN-LA. GWOGN-LA improves accuracy by applying Grey-Wolf Optimization and Gauss-Newton method. The proposed algorithm restricts the forwarding of packets in order to limit energy consumption. Simulation results show that given proposal outperforms other state-of-art algorithms in terms of accuracy and power consumption.

Published: April 2022

Machine learning is used in the health care sector due to its ability to make predictions. Nowadays major cause of death in women is due to breast cancer. In this paper, a machine learning-based framework for the diagnosis of breast cancer has been proposed. The authors have used different feature selection methods on Breast Cancer Wisconsin (Diagnostic) dataset i.e. Chi-square, Pearson correlation between features and Feature importance. The competency of the feature selection methods has been analyzed using different machine learning classifiers on different performance parameters like accuracy, sensitivity, specificity, precision, and F-measure. Random Forest (RF), Extra Tree Classifier (ETC), and Logistic Regression (LR) machine learning classifiers have been used by the authors. Results reveal that FI (Feature Importance) is the preeminent feature selection method among all others used when applied with different classifiers. Results also show that the ETC machine learning classifier gives the best accuracy result in comparison with RF and LR classifiers.

Published: April 2022

Research in information Security is very much essential as there is an increase in data breach. DNA cryptography is one of the invention in the field of data security which provides hope for an unbreakable algorithm. This paper presents a multi-level hybrid crypto system based on DNA cryptography and DNA steganography. The proposed method uses a DNA sequence from publicly available DNA data base as a onetime pad. Initially plaintext is converted into DNA form of cipher text and then using central dogma of molecular biology concept DNA strings are converted into amino acid codes which represents the protein form of data. The crux of the algorithm lies on the one-time pad used for encryption process. The proposed system combines the advantages of DNA cryptography, DNA steganography and one time pad. Security analysis shows that proposed method is strong enough to resist brute force attacks as well as cryptanalytic attacks.

Object-oriented (OO) code has many dependencies among the classes and different types of changes that often have an impact during the maintenance of the software. In this paper, we proposed a technique for change impact analysis (CIA) with fault prediction (FP) using machine learning techniques for OO software. In proposed method an intermediate OO program representation is proposed using a graph which detects the difference between the original program and the modified program. For fault prediction, class level metrics are extracted from KC1 data set and 14 machine learning algorithms are trained on dataset. The genetic algorithm (GA) and correlation are used to extract significant features from the dataset. Trained prediction models are evaluated using classification accuracy (Acc). Our proposed approach consider various types of changes possible in the program, and test cases are selected to test the modified code during regression testing and finds the fault in classes. Among the 14 machine learning algorithms random forest (RF) giving best accuracy than other algorithms.
Embedding Secret Data in Digital Media Using Texture Synthesis

Published: April 2022

A steganography is an art of hiding confidential data into digital media such as image, audio, video etc. Texture synthesis uses the concept of the patch which represents an image block of source texture where its size is user specified. A texture synthesis process resamples a smaller texture image and provides a new image with arbitrary size and shape. Instead of using an existing cover image to hide messages, the algorithm conceals the source texture image and embeds secret messages using the process of texture synthesis. This allows extracting the hidden messages and source texture from a stego synthetic texture. This offers the advantages like, First, it provides the embedding capacity that is proportional to the size of the stego texture image. Second, the reversible capability inherited from this includes functionality, which allows recovery of the source texture. And third, there will be no image distortion since the size of the new texture image is user specified.
