description: Dix ans après la parution du CECR, une nouvelle génération de moyens d’enseignement de l’allemand fait explicitement référence à l’approche actionnelle préconisée par le CONSEIL DE L’EUROPE. Quels sont les problèmes rencontrés par la « mise en manuel » de l’approche par les tâches ? Quels apports et quelles limites pour l’enseignant(e) qui s’en sert? La présente étude se pose ces questions en partant de l’exemple du manuel EINBLICK A2-B1, paru en 2010. Une première étape vise l’élaboration d’un instrument descriptif permettant de cerner la nature des décisions prises et des solutions trouvées par des auteurs de manuels basés sur les tâches. La mise en parallèle de l’introduction du manuel avec la notion de « tâche » au sens du CECR et avec les définitions et remarques d’auteurs travaillant sur l’approche par la tâches (TBLT) amène à l’hypothèse de travail suivante : en tension avec le contexte institutionnel, les critères d’efficacité du TBLT pourraient être repensés en terme de « défis » face auxquels des auteurs de manuels scolaires basés sur les tâches doivent nécessairement prendre position. Six défis ont ainsi été dégagés. (Ch. II) Interroger la façon dont les auteurs d’EINBLICK se sont situés par rapport à ces défis nécessitait ensuite une analyse descriptive du moyen d’enseignement. Présentation générale d’abord, permettant d’apprécier les choix des auteurs notamment à partir du public, du programme, du contexte auquel le manuel est destiné (Ch. III); examen global du déroulement d’une séquence type ensuite, avec analyse plus détaillée de la construction d’une tâche et d’une prétâche en particulier (Ch. IV). La conclusion (Ch. V) revient aux six défis susnommés pour leur rapporter point par point les éléments de la description du manuel où se sont manifestés des choix ou des solutions originales des auteurs. L’étude se termine sur une appréciation plus personnelle des solutions que propose EINBLICK pour la pratique.

description: Digitale Informations- und Kommunikationstechnologien gewinnen als fester Bestandteil zunehmend Bedeutung in den alltäglichen Lebenswelten einer wachsenden Zahl von Menschen. Ihre Entwicklung und selbstverständliche Nutzung schreiten in einem immer rasanteren Tempo voran; die vielfältigen Anwendungsmöglichkeiten adressieren längst alle Lebensbereiche. Während der Digitalisierung von Kommunikationsprozessen zuweilen demokratisierende Kräfte zugesprochen werden, scheint eine kritische Reflexion möglicher Potentiale und Auswirkungen digitaler Informations- und Kommunikationstechnologien auf Teilhabedynamiken in unterschiedlichen Lebensbereichen dringend erforderlich. Die Autorinnen und Autoren möchten mit dieser SI:SO-Schwerpunktausgabe einen Beitrag zu einer kritischen Reflexion digitaler Innovationen und ihrer Auswirkungen auf die zukünftige Gestaltung sozialer Dienste leisten. Mit der zweisprachigen Ausgabe ist zudem die Hoffnung verbunden, diesen Beitrag auch einem europäischen und weltweiten Publikum zugänglich zu machen.
description: Digital information and communications technologies are becoming an increasingly important part in everyday life of a growing number of people. Their development and natural use are progressing even faster with a wide range of possible applications addressing all areas of life. While the digitization of communication processes is sometimes said to have democratizing forces, critical reflection on the potential and impact of digital information and communication technologies on participation dynamics in different areas of life seems urgently needed. The Authors would like to contribute to a critical reflection on digital innovations and their impact on the future design of social services. The bilingual edition further aims to make this contribution accessible to a European and global audience.

The Socio-Technical Dynamics of Renewable Energy Policies in Germany

description: Growing environmental concerns and human-caused climate change increase the pressure on policymakers for rapid action to transform how societies convert energy, produce goods, or transport freight. Innovation and technological progress may contribute to such transitions. However, technological change is hard to predict, requires time, and may be laden with political conflicts. Although more sustainable technologies are available, incentivizing demand and deployment are crucial to accelerate transitions. As transformations develop over decades, understanding the temporal dynamics of policies is critical for governance. In Germany, the renewable energy act incentivizes the deployment of renewable energy technologies by remunerating electricity fed into the common grid. This dissertation assesses how socio-technical developments of solar and wind energy conversion technologies and the renewable energy act interactively shaped each other. Drawing on frameworks such as technological innovation systems, legitimacy, framing, and policy feedback, the contents of 16,485 newspaper articles and additional empirical studies were scrutinized. Combining methods from natural language processing, machine learning, and statistics, this thesis develops text models to assess changes in content and sentiment in large corpora over time. Three studies focus on the shifts in media framing of the German renewable energy act, the underlying co-evolution of technological and policy processes, and the development of the legitimacy of wind power. The results confirm that renewable energy deployment and policy are contested with varying intensity over time. Where change ought to occur, non-linear dynamics of innovation and technology uptake, growing policy costs, economic interests of incumbents, and technology side effects increasingly complicate policymaking over time. The early phases of the renewable energy act were shaped by positive expectations toward renewable energy technologies, which later shifted towards an emphasis on policy costs. The findings highlight the importance of the prosperity of underlying innovation systems as supporters of policy ambition and maintenance over time. However, policy costs and side effects must be managed effectively to withstand increasing contestation. These results may contribute to advancing the successful governance of sectoral transitions likely to unfold over several decades.

description: Une communauté de pratique est définie comme étant le processus d'apprentissage social qui se développe lorsque des individus partageant un intérêt commun s’engagent mutuellement pour développer leurs compétences, notamment en partageant des idées et en créant des outils communs à leur pratique. Ce mémoire professionnel présente la création d’un portail communautaire en ligne (http://moodle.gymnyon.vd.ch/combiol) dans le but de développer une communauté de pratique pour les enseignants de biologie vaudois. Selon un sondage réalisé auprès des enseignants du secondaire II vaudois, le site correspond relativement bien aux attentes de certains enseignants. De plus, grâce aux contributions des membres, la base de données contenant du matériel pédagogique est en constante progression et un sondage effectué auprès des utilisateurs après environ un an d'utilisation a montré une satisfaction globale élevée. Le site est jeune (moins d’un an) et est en constante évolution. Certains ajustements sont donc indispensables, en particulier la professionnalisation du site, d’abord technique ensuite avec un « manager de communauté » pour gérer et stimuler les interactions entre les membres.

description: A consistent set of asymptotic conditions for the simplest supergravity theory without cosmological constant in three dimensions is proposed. The canonical generators associated to the asymptotic symmetries are shown to span a supersymmetric extension of the BMS$_3$ algebra with an appropriate central charge. The energy is manifestly bounded from below with the ground state given by the null orbifold or Minkowski spacetime for periodic, respectively antiperiodic boundary conditions on the gravitino. These results are related to the corresponding ones in AdS$_3$ supergravity by a suitable flat limit. The analysis is generalized to the case of minimal flat supergravity with additional parity odd terms for which the Poisson algebra of canonical generators form a representation of the super-BMS$_3$ algebra with an additional central charge.

description: Availability of controlled vocabularies, ontologies, and so on is enabling feature to provide some added values in terms of knowledge management. Nevertheless, the design, maintenance and construction of domain ontologies are a human intensive and time consuming task. The Knowledge Extraction consists of automatic techniques aimed to identify and to define relevant concepts and relations of the domain of interest by analyzing structured (relational databases, XML) and unstructured (text, documents, images) sources. Specifically, methodology for knowledge extraction defined in this research work is aimed at enabling automatic ontology/taxonomy construction from existing resources in order to obtain useful information. For instance, the experimental results take into account data produced with Web 2.0 tools (e.g., RSS-Feed, Enterprise Wiki, Corporate Blog, etc.), text documents, and so on. Final results of Knowledge Extraction methodology are taxonomies or ontologies represented in a machine oriented manner by means of semantic web technologies, such as: RDFS, OWL and SKOS. The resulting knowledge models have been applied to different goals. On the one hand, the methodology has been applied in order to extract ontologies and taxonomies and to semantically annotate text. On the other hand, the resulting ontologies and taxonomies are exploited in order to enhance information retrieval performance and to categorize incoming data and to provide an easy way to find interesting resources (such as faceted browsing). Specifically, following objectives have been addressed in this research work:  Ontology/Taxonomy Extraction: that concerns to automatic extraction of hierarchical conceptualizations (i.e., taxonomies) and relations expressed by means typical description logic constructs (i.e., ontologies).  Information Retrieval: definition of a technique to perform concept-based the retrieval of information according to the user queries.  Faceted Browsing: in order to automatically provide faceted browsing capabilities according to the categorization of the extracted contents.  Semantic Annotation: definition of a text analysis process, aimed to automatically annotate subjects and predicates identified. The experimental results have been obtained in some application domains: e-learning, enterprise human resource management, clinical decision support system. Future challenges go in the following directions: investigate approaches to support ontology alignment and merging applied to knowledge management. [edited by Author]
Multidimensional Modelling of Magnetic Fields in Core-Collapse Supernovae and Their Progenitors

Year: 2022
Subjects: Stellar astronomy and planetary systems

description: This thesis explores the role of magnetic fields in core-collapse supernovae and in their progenitors using detailed multidimensional simulations. The role of magnetic fields in these events are often ignored due, in part, because it is assumed that unless rapid rotations are involved, the magnetic fields are too weak to be dynamically relevant. We challenge this assumption through three projects in this thesis: 1)The first code comparison of magnetorotational supernova models. 2) The first 3D magnetohydrodynamic simulation of the final minutes of Oxygen convective shell burning in a massive star. 3) 3D simulations of non-rotating strongly magnetised neutrino-driven core-collapse supernovae.

description: Electronic states confined to zero angle grain boundaries in single layer graphene are analyzed using topological band theoretic arguments. We identify a hidden chiral symmetry which supports symmetry protected zero modes in projected bulk gaps. These branches occupy a finite fraction of the interface-projected Brillouin zone and terminate at bulk gap closures, manifesting topological transitions in the occupied manifolds of the bulk systems that are joined at an interface. These features are studied by numerical calculations on a tight binding lattice and by analysis of the geometric phases of the bulk ground states.

description: High concentrations of nutrients are observed in the effluent of different wastewater treatment plants, while additional costs of post-treatment systems and low-value sludge are the main reasons for releasing such effluents. The present study aims to introduce an increased procedure for simultaneous nutrient recovery and biomass production using an algae-based post-treatment technique. The procedure has been utilized by two well-known strains (Scenedesmus dimorphus and Chlorella vulgaris) cultivated in different N/P ratios (16, 62, and 108) and trace metals (0, 50%, and 100%) in a synthetic meat processing wastewater as a model to investigate effects of the factors on microalgal cultivation and nutrient removal. Pareto statistical analysis and Multi Response Surface methodology were applied to determine the priority of factors and their optimum values, respectively. The unbalanced N/P ratio and lack of trace metals were introduced as two main reasons for the significant decrease of about 60% and 120% in nutrient removal and biomass production. The optimized procedure resulted in significant increases in the removal efficiencies where 90%, 83%, and 65% were achieved for ammonium, nitrate, and phosphate, respectively. Moreover, a 72% increase in biomass production was reported in the optimal points. The results of the Pareto analysis highlighted the significant superiority (about two times) of the trace metals in removal efficiencies. Finally, experimental data has also been modelled by Verhulst logistic model that successfully described the microalgae growth. This procedure showed promising results of microalgal systems to supersede the conventional post-treatment systems.

description: The goal of this project was to determine if the ecological integrity of meiofaunal communities was being affected by storm water outfall sediment chemistry, hydrographic parameters, or physical disturbance. Fifteen of 36 study sites were near storm water outfalls. The other 21 sites were reference or highly polluted sites to contrast the outfall sites with background levels and known chemically stressed sites. Because Corpus Christi Bay is a shallow open bay system, physical disturbance due to sediment re-suspension was also estimated. Contamination from non-point sources at storm water sites produced the highest concentrations of both trace metals and cyclic organic pollutants found in this study. Trace metal contaminants were tightly bound to the sediments, and their effects on the biotic communities can only be distinguished from background at one outfall site. Cyclic organic pollutants concentrations were elevated at 66% of the outfall sites, and effects on biotic communities can be distinguished from background at 88% of these sites. The four most contaminated storm water sites exhibited extreme reductions in measures of both macrofaunal and meiofaunal community integrity. Re-suspension was a confounding factor with organic pollutants at five relatively clean outfall sites, where it eliminated the harpacticoid copepod community, and negatively affected the macrofaunal community. In general, of the 36 sites, the 4 most degraded sites were storm water outfalls

description: In this paper, we propose a method that provides a useful technique to compare relationship between risks involved that takes customer become defaulter and debt collection process that might make this defaulter recovered. Through estimation of competitive risks that lead to realization of the event of interest, we showed that there is a significant relation between the intensity of default and losses from defaulted loans in collection processes. To reach this goal, we investigate a competing risks model applied to whole credit risk cycle into a bank loans portfolio. We estimated competing causes related to occurrence of default, thereafter, comparing it with estimated competing causes that lead loans to write-off condition. In context of modeling competing risks, we used a specification of Poisson distribution for numbers from competing causes and Weibull distribution for failures times. The likelihood maximum estimation is used to parameters estimation and the model is applied to a real data of personal loans

description: One of the major technological and scientific challenges in developing autonomous machines and robots is to ensure their ethical and safe behavior towards human beings. When dealing with autonomous machines the human operator is not present, so that the overall risk complexity has to be addressed to machine artificial intelligence and decision-making systems, which must be conceived and designed in order to ensure a safe and ethical behaviour. In this work a possible approach for the development of decision-making systems for autonomous machines will be proposed, based on the definition of general ethical criteria and principles. These principles concern the need to avoid or minimize the occurrence of harm for human beings, during the execution of the task the machine has been designed for. Within this scope, four fundamental problems can be introduced: 1. First Problem: Machine Ethics Principles or Laws Identification 2. Second Problem: Incorporating Ethics in the Machine 3. Third Problem: Human-Machine Interaction Degree Definition 4. Fourth Problem: Machine Misdirection Avoidance. This Ph.D. research activity has been mainly focused on First and Second Problems, with specific reference to safety aspects. Regarding First Problem, main scope of this work is on ensuring that an autonomous machine will act in a safe way, that is: • No harm is issued for surrounding human beings (non maleficence ethical principle) • In case a human being approaching a potential source of harm, the machine must act in such a way to minimize such harm with the best possible and available action (non-inaction ethical principle) and, when possible and not conflicting with above principles: • The machine must act in such a way to preserve its own integrity (self-preservation). Concerning Second Problem, the simplified version of some ethical principles reported above has been used to build a mathematical model of a safe decision system based on a game theoretical approach. When dealing just with safety and not with general ethics, it is possible to adopt some well-defined criteria in ensuring the machine behaviour is not issuing any harms towards human beings, such as: • Always ensure the machine is keeping a proper safety distance at a certain operating velocity • Always ensure that, within a certain range, the machine can detect the distance between a human being and the location of a potential harm.

description: Report Preface: The use of the Nation's land and water resources is receiving widespread attention. Misuse of our natural resources could have long-term adverse effects on the Nation's economy and the quality of the environment. The Federal Government, and State and local governments, have a continuing responsibility to assess the adequacy of our natural resources to meet future needs and to improve the quality of the environment. The Economic Research Service provides socio-economic information on a broad range of subjects relating to rural land and water resources, and projects future requirements for these resources. This series of articles appeared in The Farm Index issues dated December 1972 - April 1973. They are assembled here for separate release by the Natural Resource Economics Division. They provide general information on the use and ownership of our land and water resources, and project future supply and demand of these resources for different uses.

description: Adaptive bitonic sorting is a sorting algorithm suitable for implementation on EREW parallel architectures. Similar to bitonic sorting, it is based on merging, which is recursively applied to obtain a sorted sequence. In contrast to bitonic sorting, it is data dependent. Adaptive bitonic merging can be performed in O(n/p) parallel time, p being the number of processors, and executes only O(n) operations in total. Consequently, adaptive bitonic sorting can be performed in O(n log n/p) time, which is optimal. So, one of its advantages is that it executes a factor of O(log n) less operations than bitonic sorting. Another advantage is that it can be implemented efficiently on modern GPUs.

description: It is proposed that planetesimals perturbed by Jovian mean-motion resonances are the source of shock waves that form chondrules. It is considered that this shock-induced chondrule formation requires the velocity of the planetesimal relative to the gas disk to be on the order of > 7 km/s at 1 AU. In previous studies on planetesimal excitation, the effects of Jovian mean-motion resonance together with the gas drag were investigated, but the velocities obtained were at most 8 km/s in the asteroid belt, which is insufficient to account for the ubiquitous existence of chondrules. In this paper, we reexamine the effect of Jovian resonances and take into account the secular resonance in the asteroid belt caused by the gravity of the gas disk. We find that the velocities relative to the gas disk of planetesimals a few hundred kilometers in size exceed 12 km/s, and that this is achieved around the 3:1 mean-motion resonance. The heating region is restricted to a relatively narrow band between 1.5 AU and 3.5 AU. Our results suggest that chondrules were produced effectively in the asteroid region after Jovian formation. We also find that many planetesimals are scattered far beyond Neptune. Our findings can explain the presence of crystalline silicate in comets if the scattered planetesimals include silicate dust processed by shock heating.

description: We define a novel geometric predicate and a class of objects that enables us to prove a linear bound on the number of intersecting polygon pairs for colliding 3D objects in that class. Our predicate is relevant both in theory and in practice: it is easy to check and it needs to consider only the geometric properties of the individual objects – it does not depend on the configuration of a given pair of objects. In addition, it characterizes a practically relevant class of objects: we checked our predicate on a large database of real-world 3D objects and the results show that it holds for all but the most pathological ones. Our proof is constructive in that it is the basis for a novel collision detection algorithm that realizes this linear complexity also in practice. Additionally, we present a parallelization of this algorithm with a worst-case running time that is independent of the number of polygons. Our algorithm is very well suited not only for rigid but also for deformable and even topology-changing objects, because it does not require any complex data structures or pre-processing. We have implemented our algorithm on the GPU and the results show that it is able to find in real-time all colliding polygons for pairs of deformable objects consisting of more than 200k triangles, including self-collisions.

description: Ce mémoire traite des démarches mises en place dès la rentrée au au niveau de la discipline par une enseignante du CYP1/1 au sein de sa classe. Il n’a pas pour but de vérifier une hypothèse, mais plutôt de questionner et de faire un état des lieux des pratiques existantes dans une classe donnée. Voici les sous-questions que j’ai posées au début de ma recherche : - La règle de vie « Je lève la main » permet-elle de mieux réguler les interventions dans les moments collectifs ? - L’accueil des élèves le matin influence-t-il leur comportement ? - Le fait de construire les règles de vie avec les élèves et de les afficher en classe favorise-t-il la connaissance et l’application de celles-ci par les élèves ? - Un système de comportement lié aux règles de vie est-il indispensable ou non pour une bonne harmonie dans la classe? - Quelles attitudes adopter face aux élèves pour attirer leur attention et exiger le silence? - Existe-t-il des méthodes, des marches à suivre pour gérer la discipline en classe ? Cette recherche s’est effectuée selon deux modalités : d’une part des observations spontanées ou planifiées, d’autre part un entretien avec ma praticienne formatrice. Premièrement, j’ai donc observé sur le terrain l’enseignante et ses manières de gérer la discipline en me basant sur des grilles d’observations ou en prenant des notes dans mon journal de bord lorsqu’une situation intéressante se présentait. Mes observations portent sur le premier matin de la rentrée, l’accueil des élèves le matin, les règles de vie et le système de comportement, mais concernent également les interventions de l’enseignante au niveau de la gestion du bruit. Deuxièmement, j’ai mené un entretien avec l’enseignante. Cet entretien était dirigé, étant donné que j’avais établi à l’avance l’ordre et la formulation des questions. Il abordait les mêmes thématiques que celles que j’avais relevées pour mes observations. Par la suite, j’ai analysé les données récoltées dans le but de dresser un portrait de la classe observée. Les données de l’entretien ont été insérées dans les différents résultats. J’ai tiré des conclusions sur les pratiques mises en place dans la classe en établissant des liens entre la théorie et la pratique. Mes lectures m’ont donc permis d’affiner mon analyse pour interpréter mes résultats. Cette récolte d’ « outils » et de moyens utilisés pour gérer la discipline m’aidera à choisir de manière plus pertinente ce que je mettrai en place dans ma future classe.

The role of BRST charge as a generator of gauge transformations in quantization of gauge theories and Gravity

description: In the Batalin - Fradkin - Vilkovisky approach to quantization of gauge theories a principal role is given to the BRST charge which can be constructed as a series in Grassmannian (ghost) variables with coefficients given by generalized structure functions of constraints algebra. Alternatively, the BRST charge can be derived making use of the Noether theorem and global BRST invariance of the effective action. In the case of Yang - Mills fields the both methods lead to the same expression for the BRST charge, but it is not valid in the case of General Relativity. It is illustrated by examples of an isotropic cosmological model as well as by spherically-symmetric gravitational model which imitates the full theory of gravity much better. The consideration is based on Hamiltonian formulation of General Relativity in extended phase space. At the quantum level the structure of the BRST charge is of great importance since BRST invariant quantum states are believed to be physical states. Thus, the definition of the BRST charge at the classical level is inseparably related to our attempts to find a true way to quantize Gravity.
description: 6 pages, the paper is based on the talks presented at the International Symposium "Frontiers of Fundamental Physics" (Marseille, France, 15 - 18 July 2014) and the International Conference "Quantum Field Theory and Gravity" (Tomsk, Russia, 28 July - 3 August 2014)
Recovery Risk: Application of the Latent Competing Risks Model to Non performing Loans

description: This article proposes a method for measuring the latent risks involved in the recovery process of non performing loans in financial institutions and business firms that deal with collection and recovery processes. To that end, we apply the competing risks model referred to in the literature as the promotion time model. The result achieved is the probability of credit recovery for a portfolio segmented into groups based on the information available. Within the context of competing risks, application of the technique yielded an estimation of the number of latent events that concur to the credit recovery event. With these results in hand, we were able to compare groups of defaulters in terms of risk or susceptibility to the recovery event during the collection process, and thereby determine where collection actions are most efficient. We specify the Poisson distribution for the number of latent causes leading to recovery, and the Weibull distribution for the time up to recovery. To estimate the model parameters, we use the maximum likelihood method. Finally, the model was applied to a sample of defaulted loans from a financial institution.

description: The photocatalytic reduction of Cr6+ to Cr3+ in an aqueous solution, using 3 wt% Ag/g-C3N4 in the presence of ethylenediaminetetraacetic acid (EDTA), has been investigated here. The photocatalytic reduction of Cr6+ with pure g-C3N4 was very low. The addition of Ag and EDTA can significantly improve the photocatalytic reduction of Cr6+ using g-C3N4. In the presence of EDTA, the efficiency with Ag/g-C3N4 was better than those with Au/g-C3N4 and Cu/g-C3N4. With EDTA, the reduction rate constant increased from 0.0005 for pure g-C3N4 to 0.12 min−1 for 3 wt% Ag/g-C3N4. By increasing the concentration of EDTA from 0 to 500 mg L−1, the reduction efficiency of Cr6+ increased extremely, and the rate constant raised from 0.008 to 0.12 min−1. The optimal EDTA concentration was 500 mg L−1 for the photocatalyst Ag/g-C3N4. The Ag-EDTA complex may be reduced to metallic silver by the conduction band electrons of g-C3N4. The electron–hole recombination was significantly suppressed by the electron trapping of Ag. EDTA may act in by the formation of Cr3+-complex and the separation of Cr3+ from the g-C3N4 surface and by the valence band hole scavenger of g-C3N4. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), UV–Vis diffuse reflectance spectroscopy (DRS) and photoluminescence spectra (PL) were used to characterize g-C3N4 and Ag/g-C3N4 nanoparticles. A possible mechanism for photocatalytic Cr6+ reduction has also been demonstrated.
Comment créer un climat favorable en développant la singularité de chacun ?

description: Le cadre théorique, dans lequel ce mémoire s'inscrit, se fonde sur le développement social de l’enfant. Royer déﬁnit quatre facteurs qui permettent à l’enfant de se construire socialement : "l’apport de la vie familiale, le tempérament, l’estime de soi ainsi que les capacités à résoudre les conﬂits interpersonnels" (2004, p.71 à 74). Avec ces bagages, l’enfant va ensuite vivre en groupe, et cela va continuer de l’enrichir : "La vie de groupe présente notamment l’avantage de mettre en évidence le caractère unique de l’enfant, de lui faire prendre conscience de ses propres capacités et de le rendre réceptif au point de vue d’autrui, ce qui est essentiel en société". (Royer, 2004, p.67) Cette recherche tente d'apporter des exemples concrets permettant d'appuyer les bases théoriques amenées par Royer, à l’aide d’observations, d'entretiens et de sociogrammes, au sein d’un groupe d’élève de deuxième enfantine. En effet, ces outils ont été mis en place pour avoir une « image » momentanée des relations entre pairs dans la classe. Puis un dispositif a été utilisé ainsi que trois albums de jeunesse, comme outils médiateurs. Tous parlent de différence, d’unicité ou encore de singularité qui montrent l’importance de chacun. La problématique de cette recherche vise à comprendre si les élèves deviennent plus tolérants les uns envers les autres en ayant pu mener une réﬂexion personnelle sur la question de la différence. De plus, elle tend à qualiﬁer la manière dont les élèves parviennent ou non à transposer cette réalité pour leurs pairs, dimension évaluée à l'aide du second sociogramme. Les entretiens et les observations faits en janvier 2011 ont permis de développer l’impact de ce travail.

description: Florida produced 76 percent of a record 8.5-million-ton U.S. orange crop in 1971/72. Over 90 percent of Florida's crop was processed, mainly into frozen concentrated orange juice. Florida supplied 89 percent of all U.S. oranges processed, but only 32 percent of all U.S. oranges sold fresh. Production in Florida increased substantially during 1958/59-1971/72. Although the retail value of Florida oranges sold fresh in Chicago and New York City trended upward during that time, the marketing margin increased faster. Derived grower returns for these oranges trended downward during the period. Consumers in the two cities paid more for an equivalent quantity of juice from fresh oranges than from frozen concentrate. Both the marketing margin and grower returns were generally higher for fresh oranges than for frozen concentrate.
