Published: September 2021

Establishing the identity of an individual is the foremost criteria for law agencies, medicolegal experts andexperts in forensic science to correlate evidences and find motive behind the crime. Forensic science hasmade an astonishing progress in the field of forensic science from blood grouping to D.N.A fingerprinting&Anthropometry to Dactylography. Nevertheless, the most commonly used tool for identification beyond theforensic laboratories still remains the same i.e. built, complexion, stature, colour of eye, mole, scar mark etc.Hence, the aim of this current study is to establish a relationship between the dimension of foot and statureestimation. The present study was conducted among 200 medical students, out of which 100 were malestudents and 100 were female students. All the students were between the age group of 20-30 years. The datawas analyzed using S.P.S.S (I.B.M version 20, Armonk, NY, U.S.A). The regression analysis showed thatthere is significant correlation between the foot parameters and stature.

Haben Unternehmen noch alle Behälter im Blick?
Authors: Bolte Nils-Ole
Published: September 2021

Ob fest, flüssig oder lose – ohne die richtigen Behälter für feste oder flüssige Güter geht in der Logistik praktisch nichts. Und doch passiert es immer wieder, dass Paletten, Big Bags und Co. entlang der Lieferkette auf der Strecke bleiben. Etwa 20 Prozent aller Mehrwegbehälter gehen verloren, weil Kunden sie für den eigenen Gebrauch zurückhalten oder Dritte sie für ihren Gebrauch entnehmen (Thoroe, 2009)! Fakt ist: Wo Güter meist so genau wie möglich abgerechnet werden, fehlt über die Behälter häufig eine konsequente Nachverfolgung. Das kann unnötige Zusatzkosten verursachen, denn wo Behälter fehlen, müssen sie erst gefunden, bei einem Partner extra abgeholt – oder im schlimmsten Fall sogar nachgekauft werden. Ein effizientes Behältermanagement kann hier Abhilfe schaffen.

Authors: Hausmann Ludwig , Fleischer Jürgen
Published: September 2021

Um wirtschaftlich auf die volatilen Marktanforderungen der Elektromobilität reagieren zu können, muss der Maschinen- und Anlagenbau den Automobilherstellern stückzahl- und variantenflexible Produktionslösungen bereitstellen. Im Kontext der Fertigung von Statoren mit Hairpin-Wicklung sind diesbezüglich die werkzeuggebundenen Prozessschritte zur Hairpin-Formgebung sowie zum Twisten der offenen Spulenenden zu fokussieren. Eine Perspektive für das flexible Twisten bis hin zur Losgröße 1 stellt ein neuer Ansatz mittels kinematischer Prozessführung dar.

 

In order to be competitive with regard to the volatile market requirements of electro mobility, mechanical and plant engineering must provide automobile manufacturers with manufacturing solutions that are flexible in terms of quantities and variants. In the context of stator production with hairpin winding, the tool-bound process steps for hairpin shaping and twisting of the open coil ends must therefore be focused on. A new approach using a kinematic process setup offers a perspective for flexible twisting up to batch size 1.

We improve the basic lemma of the theory of critical Markov branching processes and refine known limit results.
L'harmonisation des lois cantonales d'aide sociale - Une analyse des obligations internationales des droits humaines
Authors: Marlétaz Raphaël
Published: September 2021

The federal constitution gives the Swiss cantons a great deal of freedom to regulate their social welfare systems. There are still great differences in this area. People living in Switzerland, depending on their place of residence, do not all have access to the same benefits and therefore do not enjoy the same protection against poverty. This phenomenon has a significant impact on the enjoyment of human rights, which are the subject of international conventions ratified by Switzerland and which must be implemented throughout the country. In this context, this book examines whether these international guarantees require a harmonization of cantonal social welfare laws. In the light of the recent global pandemic of COVID-19, which does not stop at the cantonal borders and which severely affects the precarious populations of Switzerland, this question is very topical. The author responds to this question by demonstrating, according to several legal criteria, different concrete obligations of harmonization. This approach makes it possible to move towards a global response to a problem that affects and will affect in the future many individuals of the Swiss population, regardless of where they live: poverty. This doctoral thesis was defended on September 7, 2020 at the Faculty of Law of the University of Lausanne. The jury, composed of Professor Evelyne Schmid (thesis director), Professor Pascal Mahon, Professor Kurt Pärli, Professor Véronique Boillet and Professor Vincent Martenet, admitted this thesis with magna cum laude.

It has been implicitly assumed that ices on grains in molecular clouds and protoplanetary disks are formed by homogeneous layers regardless of their composition or crystallinity. To verify this assumption, we observed the H2O deposition onto refractory substrates and the crystallization of amorphous ices (H2O, CO2, and CO) using an ultra-high-vacuum transmission electron microscope. In the H2O-deposition experiments, we found that three-dimensional islands of crystalline ice (Ic) were formed at temperatures above 130 K. The crystallization experiments showed that uniform thin films of amorphous CO and H2O became three-dimensional islands of polyhedral crystals; amorphous CO2, on the other hand, became a thin film of nano-crystalline CO2 covering the amorphous H2O. Our observations show that crystal morphologies strongly depend not only on the ice composition but also on the substrate. Using experimental data concerning the crystallinity of deposited ices and the crystallization timescale of amorphous ices, we illustrated the criteria for ice crystallinity in space and outlined the macroscopic morphology of icy grains in molecular clouds as follows: amorphous H2O covered the refractory grain uniformly, CO2 nano-crystals were embedded in the amorphous H2O, and a polyhedral CO crystal was attached to the amorphous H2O. Furthermore, a change in the grain morphology in a protoplanetary disk is shown. These results have important implications for the chemical evolution of molecules, nonthermal desorption, collision of icy grains, and sintering.
Kilonovae Across the Nuclear Physics Landscape: The Impact of Nuclear Physics Uncertainties on r-process-powered Emission

Published: September 2021

Merging neutron stars produce “kilonovae”—electromagnetic transients powered by the decay of unstable nuclei synthesized via rapid neutron capture (the r-process) in material that is gravitationally unbound during inspiral and coalescence. Kilonova emission, if accurately interpreted, can be used to characterize the masses and compositions of merger-driven outflows, helping to resolve a long-standing debate about the origins of r-process material in the Universe. We explore how the uncertain properties of nuclei involved in the r-process complicate the inference of outflow properties from kilonova observations. Using r-process simulations, we show how nuclear physics uncertainties impact predictions of radioactive heating and element synthesis. For a set of models that span a large range in both predicted heating and final abundances, we carry out detailed numerical calculations of decay product thermalization and radiation transport in a kilonova ejecta with a fixed mass and density profile. The light curves associated with our models exhibit great diversity in their luminosities, with peak brightness varying by more than an order of magnitude. We also find variability in the shape of the kilonova light curves and their color, which in some cases runs counter to the expectation that increasing levels of lanthanide and/or actinide enrichment will be correlated with longer, dimmer, redder emission.
Jupiter as a Rotating Bipolytrope
Authors: Kadam Kundan
Published: September 2021

Polytropes have long been used to model a wide variety of astrophysical objects. A bipolytrope (composite polytrope) may be used for bodies with a distinct core-envelope structure. In this short paper, I demonstrate that a rotating bipolytrope is a reasonable approximation for Jovian interior. Similar models may be used to probe rotating exoplanets to gain an intuitive understanding of their internal structure.

While it has long been known that Titan’s haze and atmosphere are dynamic on seasonal timescales, recent results have revealed that they also exhibit significant subseasonal variations. Here, we report on observations of Titan acquired over an eight-month period between 2014 April and 2015 March with the Spectrograph for Integral Field Observations in the Near Infrared instrument on the Very Large Telescope using adaptive optics. These observations have an average five-day cadence, permitting interrogation of the short-period variability of Titan’s atmosphere. Disk-resolved spectra in the H and K bands (1.4–2.4 μm) were analyzed with the PyDISORT radiative transfer model to determine the spatial distribution and variation of stratospheric haze opacity over subseasonal timescales. We observed a uniform decrease in haze opacity at 20°N and an increase in haze opacity at 250–300°E and ∼40°N over the span of our observations. Globally, we found variations on the order of 5%–10% on timescales of weeks, as well as a steady, global increase in the amount of haze over timescales of months. The observed variations in haze opacity over the short timescales of our observations were of similar magnitude to long-period variations attributed to seasonal variation, suggesting rapid dynamical processes that may take part in the distribution of hazes in Titan’s atmosphere.
Morphological Evolution of Ordinary Chondrite Microstructure during Heating: Implications for Atmospheric Entry
Authors: Panerai Francesco , Bessire Brody , Haskins Justin , Foster Collin , Barnard Harold , Stern Eric , Feldman Jay
Published: September 2021

Meteoroid entry physics remain poorly understood, owing to the extreme conditions experienced by the meteoroid during hypervelocity atmospheric passage, which are not reproducible in ground-test facilities. Therefore, much of our knowledge of fundamental processes is based on bolide lightcurve inference and a posteriori analysis of recovered meteorites. Here, novel in situ microtomography experiments at entry-relevant temperatures were performed on samples of two ordinary chondrites: Tamdakht (H5) and Tenham (L6). The two meteorites were imaged while undergoing a temperature ramp from room temperature to 1200°C. A machine-learning mediated analysis of the microstructural evolution reveals incongruent melting of the meteorite, initiated by the meteoritic iron and iron sulfide grains, and subsequent flow through microcracks that leads to the evolution of large voids. This behavior is correlated to a broad, high-temperature endotherm, noted from differential scanning calorimetry analysis, indicative of the heat of fusion of the melting grains. Correspondingly, a surface elemental analysis indicates that the sulfur species in iron sulfide are highly mobile, which can result in the formation of nonstoichiometric iron–sulfur compounds with melting points that span the temperature range of the observed endotherm. The implications for entry phenomena, in particular meteoroid ablation, are discussed.
Two new genera and three new species of cavernicolous trechines from the western Wuling Mountains, China (Coleoptera, Carabidae, Trechinae)
Authors: Tian Mingyi , Huang Sunbin , Jia Xinyang , Zhao Yi
Published: September 2021

Two new genera and three new species of cave-adapted ground beetles belonging to the tribe Trechini are established and described: Wulongius qilingergen. nov. and sp. nov. from limestone cave Qiankou Dong (Chongqing: Wulong), Qianotrechus congcongaesp. nov. from cave Shigao Dong (Chongqing: Nanchuan), and Qianlongius zhouigen. nov. and sp. nov. from cave Qianlong Dong (Guizhou: Songtao). Wulongius qilingersp. nov. is a small aphaenopsian beetle with a thin and elongated body, while Qianlongius zhouisp. nov. is a semi-aphaenopsian with a stout body. Both new genera are not closely related to any genus of Trechini occurring in the South China Karst, and so their systematic positions remain unclear.
Atteindre les objectifs organisationnels non priorisés par les individus : le rôle des Systèmes de Contrôle de Gestion au sein du processus de régulation de l’attention
Authors: Allain Élodie , Tessier Sophie
Published: September 2021

L’attention des décideurs est considérée depuis de nombreuses années comme une ressource rare. L’accroissement du nombre d’objectifs organisationnels a amplifié ce phénomène dans les organisations où différents Systèmes de Contrôle de Gestion (SCG) sont mobilisés pour orienter l’attention des décideurs sur ces objectifs. Toutefois, l’influence de ces SCG trouve ses limites dans les capacités attentionnelles des individus qui, en cas de surcharge cognitive, priorisent certains objectifs. La multiplication des SCG n’est donc pas une réponse suffisante. Les SCG doivent également permettre d’encadrer la priorisation des objectifs par les individus (Simons 1995 ; Sundin et al. 2010 ; Sundin et al. 2017). Cet article vise à comprendre comment les SCG orientent l’attention des décideurs sur les objectifs organisationnels qu’ils ne priorisent pas a priori. Pour y parvenir, nous mobilisons une perspective dédiée au processus de régulation de l’attention, l’«  Attention-Based-View of the firm » (ABV) (Ocasio 1997, 2011). Nos résultats contribuent à la littérature en contrôle en positionnant les SCG dans un processus de régulation de l’attention qui favorise la construction d’une attention collective pour atteindre les objectifs organisationnels et en montrant le rôle clé des contrôles par les canaux de communication. Nos résultats montrent également l’importance de comprendre l’influence des SCG selon leur catégorie (contrôles structurels ou situationnels) pour encadrer la priorisation des objectifs par les décideurs. Enfin, nos résultats contribuent à la littérature sur l’ABV en montrant le rôle joué par les SCG dans le processus de régulation de l’attention et en proposant d’intégrer les SCG dans le modèle de l’ABV.
La fabrication de la sous-utilisation des outils de gestion : une étude longitudinale d’un progiciel CRM
Authors: Dambrin Claire , Grall Bénédicte
Published: September 2021

Cette étude vise à comprendre un phénomène pris pour acquis dans les organisations : la sous-utilisation des outils de gestion. Nous nous intéressons à un outil de gestion en particulier, un progiciel de gestion de la relation client dont nous avons suivi l’implantation et les usages sur une période de 10 ans (2002-2012) dans une entreprise française de distribution de publicité en boîtes aux lettres. Nous nous appuyons sur les travaux de la théorie de l’Acteur-Réseau et plus particulièrement sur les concepts de script, d’interaction entre les utilisateurs et les objets techniques (Akrich 2006a, 2006b) et d’intéressement pour identifier les racines de la sous-utilisation du CRM. Nos résultats montrent que la sous-utilisation se fabrique. Elle se crée à partir de trois dynamiques d’intéressement : l’abandon d’intéressement des utilisateurs, l’anti-intéressement et un intéressement à court terme se transformant en désintéressement sur le long terme. Ces résultats nous permettent de revisiter les recherches comptables sur le cycle de vie des outils de gestion et sur les vernaculaires.
Des chiffres discutables. Quand les partenaires sociaux négocient les indicateurs de l’égalité professionnelle
Authors: Chappe Vincent-Arnaud , Demilly Hélène
Published: September 2021

Cet article traite des usages du « rapport de situation comparée entre femmes et hommes », produit par les entreprises françaises de plus de 50 salarié·e·s, et devant servir d’appui à la négociation de l’égalité professionnelle entre partenaires sociaux. Ce rapport, produit par les directions des ressources humaines à destination des syndicats et composé principalement d’indicateurs quantifiés, échoue la plupart du temps à produire un consensus sur la situation de l’entreprise au regard de l’objectif d’égalité. Les représentants des salarié·e·s ne restent pas passifs devant les données qui leur sont présentées : ils produisent un discours critique visant la qualité ou le sens des chiffres qui leur sont, demandent d’autres indicateurs et, dans les cas où ils en ont la possibilité, produisent une quantification alternative des inégalités sexuées. Si les nombres ne jouent pas le rôle de « juge de paix » entre les partenaires sociaux, ils permettent néanmoins dans certains cas d’initier une démarche de discussion critique au sein de l’entreprise.
Comment les employés d’une chaîne de magasins de commerce de détail et les clients répondent aux différentes configurations LMX : une analyse longitudinale
Authors: Tremblay Michel , Sajadi Pegah , Parent-Rocheleau Xavier
Published: September 2021

Cet article examine les effets des configurations de LMX perçues par les employés qui interagissent avec des clients sur le climat de justice procédurale, sur le comportement de service orienté client et sur le montant dépensé par les clients. Les résultats basés sur des données multi-sources de 29 magasins, recueillies à six occasions (1 857 employés de première ligne et 20 524 clients) d’un grand détaillant canadien, mettent en évidence la nature paradoxale de la configuration LMX. Plus précisément, les employés des magasins avec une forte proportion de configuration LMX minoritaire, en comparaison aux unités avec une proportion plus élevée de configuration LMX égalitaire, tendent à expérimenter un plus faible niveau de climat de justice procédurale, mais à déployer paradoxalement plus de comportements de service orienté client et à engendrer des dépenses annuelles plus élevées de la part des clients. À l’inverse, les employés de magasins ayant une proportion plus élevée de configuration LMX fragmentée, en comparaison avec la configuration LMX égalitaire, tendent à afficher moins de comportements de service orienté client et de plus faibles dépenses annuelles des clients. Cette étude montre également que les configurations LMX perçues se répercutent sur le montant dépensé par les clients, par l’entremise du climat de justice et des comportements de service.

Cities are playing an increasingly important role in the development and growth of countries. A country's growth and prosperity is largely dependent on the efficient functioning of its cities. The reliance of countries on the ability of their cities to perform crucial central functions, for national growth, continues to rise. South Africa has a long-standing network of cities, towns and localities. These have developed and become hierarchised over the course of history during which population settlements and their distribution have been influenced by colonisation, segregation, industrialisation and globalisation. Since 1911, South Africa has undergone an extended phase of intense urban growth, with areas such as Johannesburg, Cape Town and eThekwini (Durban) agglomerating into dominating economic spaces. There are, however, no universally accepted, distinct criteria that constitute the general characteristics of secondary cities. The common assumption is that secondary cities are those cities that find themselves below the apex of what are considered primary cities. Furthermore, internationally, secondary cities appear to be considered as important catalysts for balanced and dispersed economic growth. In the South African context, the notion of what constitutes secondary cities is to a large extent underdeveloped. The aim of the paper is to appraise interconnected regional networks as a differentiated and novel outlook when determining secondary cities in South Africa. What is evident from the paper is that there are different potential alternatives with which to portray secondary cities.

Recently, renewable energies have attracted the significant attention of scientists. Nanofluids are fluids carrying nano-sized particles dispersed in base fluids. The improved heat transfer by nanofluids has been used in several heat-transfer applications. Nanofluids' stability is very essential to keep their thermophysical properties over a long period of time after their production. Therefore, a global approach including stability and thermophysical properties is necessary to achieve the synthesis of nanofluids with exceptional thermal properties. In this context, the objective of this paper is to summarize current advances in the study of nanofluids, such as manufacturing procedures, the mechanism of stability assessment, stability enhancement procedures, thermophysical properties, and characterization of nanofluids. Also, the factors influencing thermophysical properties were studied. In conclusion, we discuss the application of nanofluids in solar collectors.

Machine Learning Prediction and Recommendation Framework to Support Introductory Programming Course
Authors: Khan Ijaz Muhammad , Ahmad Abdul Rahim , Jabeur Nafaa , Mahdi Mohammed Najah
Published: September 2021

The new students struggle to understand the introductory programming courses, due to its intricate nature, which results in higher dropout and increased failure rates. Despite implementing productive methodologies, the instructor struggles to identify the students with distinctive levels of skills. The modern institutes are looking for technology-equipped practices to classify the students and prepare personalized consultation procedures for each class. This paper applies decision tree-based machine learning classifiers to develop a prediction model competent to forecast the outcome of the introductory programming students at an early stage of the semester. The model is then transformed into an adaptive consultation framework which generates three types of colored signals; red, yellow, and green which illustrates whether the student is performing low, average, or high respectively. This provides an opportunity for the instructor to set precautionary measures for low performing students and set complicated tasks that help the highly skilled students to improve their skills further. The experiments compare a set of decision tree-based classifiers and conclude J48 as an efficient model in classifying students in all classes with high accuracy, sensitivity, and F-measure. Even though the aim of the research is to focus on introductory programming courses, however, the framework is flexible and can be implemented in other courses.

Published: September 2021

With the advancement of ICT in the 21st century, ICT adopted education environment and teaching approaches are introduced in Higher Education setting globally. In the year of 2020 when global education sector encountered unprecedent difficult phenomena in Covid-19 Pandemic, teachers, students, and education administrators had to familiar with the terminology of online platform, hybrid learning and Flipped Learning (FL). With this strong intervention of ICT into the Education setting, this study aims to explore the students’ experience and perception toward the FL by analyzing and interpreting interview data from the qualitative studies on FL between 2014 and 2020. This study conducted text mining analysis, and topic modeling method from the selected 102 SSCI and Scopus level research articles on FL. The result of the study categorized the findings from the pure text analysis into three themes for the FL which were ‘teacher and classroom’, ‘motivation and students’ growth’, ‘educational needs and difficulties. From the result, the study confirmed the other two key topics which are related to student’ experience and characteristics such as growth of motivation, practical challenges, and difficulties from the FL experience. The result indicates that teachers need to give attentive attention and observation to the challenges that students are encountering during the classroom activities in FL setting.

Considering the increased interest in ensuring the well-being of a person, lifelong learning takes a leading place in society. The purpose of this study is to build the concept of the LLL system for the Republic of Kazakhstan based on the methodology of education and international best practices, as well as global trends in the development of education. The key idea of the study is to justify the LLL system, which provides coverage of the country's population with formal, non-formal and informal learning to increase its competitiveness and basic competencies to the level of the OECD countries. To do this, we propose mechanisms that allow us to fully recognize the learning outcomes of formal, non-formal and informal education.
These ideas were proposed by the authors to the Kazakhstan’s Government
on the development of the Concept of Lifelong Learning.
Use of Virtual Reality Technology in Animation Course Teaching
Authors: Ji Yuanyuan
Published: September 2021

With the rapid development of Internet technology, in consequence of the outbreak of COVID-19, colleges and universities have postponed the start of term, in order to protect the life safety of teachers and students. However, to avoid affecting students’ academic studies, colleges and universities have taken various virtual reality technologies to implement personalized online teaching on students. However, there are still some problems in actual teaching, such as the monotonous teaching mode of animation course, which results in students’ lack of practical animation operation ability; the lectures lay too much emphasis on the textbook content and the pedagogical knowledge in animation is not updated, etc. In our study, we will combine Animation Teaching mode with the educational concept of STEAM, and designs a teaching mode oriented to students’ needs. This teaching mode include five parts: analysis of students’ needs, analysis of learning goals, selection of learning strategies, design of learning activities and design of learning evaluation. At the same time, based on the American Customer Satisfaction Index (ACSI) Model, our study will also investigate student satisfaction from four dimensions: student expectations, students’ perceived quality, students’ perceived value and student loyalty, with a view to measure the effectiveness of this teaching model. Through the teaching practice, it is found that this teaching mode can significantly promote students’ grades and motivate their enthusiasm for learning. The students’ autonomic learning and mastery of professional knowledge are significantly superior to those of traditional multimedia teaching method. The proposed teaching mode offers an objective reference for the application of virtual reality technology in teaching.
Current State of Art Design Education in Colleges and a New Hybrid Learning Mode
Authors: Liang Jing
Published: September 2021

Art design education contributes immensely to social and economic development. To train art designers that suit social development and industrial needs, colleges must substantially reform their art design education. From the perspective of cultivating the core literacy, this paper carries out a survey on the current state of art design education in colleges. The survey reveals the following problems of art design education in Chinese colleges: the students have a poor cultural literacy, a low interest in professional learning, and a weak understanding of the core literacy; the faculty has an unreasonable structure, an overall weak competence, a monotonous teaching method, and the detachment of theories from practices. Based on the survey results, a hybrid learning mode was derived from project-based learning, and the application effect of the proposed mode in art design education was analyzed from the perspective of the cultivation of core literacy. The results show that, the proposed learning mode can effectively enhance teaching quality, and improve the core literacy and professional ability of students. The research provides a valuable theoretical and practical reference for the reform of art design education.

This study presents a novel framework based on a heterogeneous ensemble method and a hybrid dimensionality reduction technique for spam detection in micro-blogging social networks. A hybrid of Information Gain (IG) and Principal Component Analysis (PCA) (dimensionality reduction) was implemented for the selection of important features and a heterogeneous ensemble consisting of Naïve Bayes (NB), K Nearest Neighbor (KNN), Logistic Regression (LR) and Repeated Incremental Pruning to Produce Error Reduction (RIPPER) classifiers based on Average of Probabilities (AOP) was used for spam detection. The proposed framework was applied on MPI_SWS and SAC’13 Tip spam datasets and the developed models were evaluated based on accuracy, precision, recall, f-measure, and area under the curve (AUC). From the experimental results, the proposed framework (that is, Ensemble + IG + PCA) outperformed other experimented methods on studied spam datasets. Specifically, the proposed method had an average accuracy value of 87.5%, an average precision score of 0.877, an average recall value of 0.845, an average F-measure value of 0.872 and an average AUC value of 0.943. Also, the proposed method had better performance than some existing methods. Consequently, this study has shown that addressing high dimensionality in spam datasets, in this case, a hybrid of IG and PCA with a heterogeneous ensemble method can produce a more effective method for detecting spam contents.

Abstrait-

Ce travail vise à étudier comment une expérience de formation à distance de trois jours pour enseignants, programmée d'urgence, pour développer chez ces enseignants les capacités d'utilisation de la plateforme numérique, la création et la gestion de ressources numériques, ainsi que la création et la gestion d'un évaluation, afin qu'ils soient en mesure d'assurer correctement la continuité pédagogique. La mise en place de ce mode de formation a été recommandée dans un état d'urgence en raison de la pandémie de Corona Virus qui a été connue dans le monde entier et qui a provoqué la fermeture des écoles, ce qui a forcé le passage du mode présentiel à l'enseignement à distance, au cours de l'année 2020. Cette formation à distance, qui concerne les enseignants des écoles, était nécessaire pour développer leurs capacités à utiliser ce nouveau mode d'enseignement.

A partir du cadre de l'évaluation de la formation professionnelle, et à travers les outils de collecte de données construits et utilisés dans cette recherche, les résultats montrent une certaine évolution dans les conceptions de ces enseignants pour revisiter les objectifs de cette formation par les enseignants-formateurs pour son déploiement éventuel.
