Cette recherche vise à analyser la communication pédagogique multimodale dans des mondes synthétiques (virtuels). L'étude se focalise sur le rapport entre le verbal et le non verbal et son rôle de soutien pour la production et la participation verbales en langue étrangère. Celui-ci est analysé dans une perspective socio-sémiotique de la multimodalité, dans le contexte d'une formation conduite dans le monde synthétique Second Life selon une approche Enseignement d'une Matière Intégré à une Langue Étrangère (Emile). La formation, 'Building Fragile Spaces' menée dans le cadre du projet européen ARCHI21 a été conçue pour des étudiants d'architecture dont la langue étrangère était soit le français soit l'anglais.Le rapport entre le verbal et le non verbal est examiné selon trois angles différents. Premièrement, le rôle du non verbal pendant une activité de construction collaborative est analysé au vu des opportunités offertes par des mondes synthétiques pour la co-création de l'environnement et pour la collaboration. A travers cette étude, nous nous demandons si l'utilisation du mode non verbal a un impact sur la participation des étudiants dans le mode verbal et si le rapport entre ces deux modes a une influence sur la production verbale. Deuxièmement, l'utilisation du non verbal pour la construction des identités est abordée et est considérée en rapport avec l'interaction et la participation verbale des étudiants dans la langue étrangère. Finalement, la recherche se concentre sur le rapport entre les modalités audio et clavardage dans le mode verbal. Plus particulièrement, l'étude s'intéresse au rôle du clavardage dans l'interaction puisqu'il est en compétition non seulement avec l'audio mais également avec plusieurs modalités non verbales. La possibilité d'utiliser le clavardage pour la rétroaction est également abordée.Cette thèse cherche à contribuer aux considérations méthodologiques exigées pour que la recherche concernant la communication pédagogique multimodale dans des mondes synthétiques puisse aller au-delà des exemples spéculatifs et anecdotiques. Une typologie de modalités verbales et non verbales est proposée. Elle sert à étendre une méthodologie proposée pour la transcription des interactions multimodales aux interactions possibles dans les mondes synthétiques. En vue de la problématique plus générale, dans les domaines des Sciences Humaines et des Sciences du Langage, il s'agit de rendre visibles et accessibles publiquement les données utilisées pour les analyses. En effet, cette étude se réfère à un corpus d'apprentissage dans son approche méthodologique. La construction d'un corpus structuré permet d'effectuer des analyses contextualisées des données recueillies lors de la formation 'Building Fragile Spaces'.Cette recherche propose quelques éléments de réponse concernant l'augmentation de la participation verbale en rapport avec l'organisation proxémique des étudiants, la customisation de l'apparence des avatars des étudiants et l'utilisation importante des actes non verbaux. Concernant la production verbale, l'étude décrit comment, dans le mode non verbal, le mouvement de l'avatar est employé en tant que stratégie pour surmonter des difficultés de communication dans le mode verbal. Ces difficultés concernent, en particulier, l'expression de la direction et de l'orientation. L'étude montre également l'intérêt d'utiliser le clavardage pour offrir de la rétroaction concernant la forme linguistique dans le but de soutenir la production verbale des apprenants dans la modalité audio. Au vu des résultats, l'étude propose quelques considérations concernant la conception des activités pédagogiques pour l'apprentissage des langues dans des mondes synthétiques. / This research focuses on multimodal pedagogical communication in synthetic (virtual) worlds. The study investigates the interplay between verbal and nonverbal interaction which supports verbal participation and production in a foreign language. This is analysed from a socio-semiotic perspective of multimodality within the context of a course held in the synthetic world Second Life, which adopted a Content and Language Integrated Learning (CLIL) approach. The course, entitled 'Building Fragile Spaces', formed part of the European project ARCHI21. It was designed for higher education students of Architecture whose foreign language was either French or English.The interplay between verbal and nonverbal interaction is examined from three different angles. Firstly, considering the opportunities synthetic worlds offer for the co-creation of the environment through building activities and for collaboration, the role played by the nonverbal mode during a collaborative building activity is investigated. The study questions whether the use of the nonverbal mode impacts on the participation of students in the verbal mode, and whether any interplay exists between these two modes that influences verbal production. Secondly, use of the nonverbal mode by students in inworld identity construction is addressed and considered with reference to their verbal interaction, and participation, in the foreign language. Thirdly, the research concentrates upon interplay between the audio and textchat modalities in the verbal mode. More specifically, the focus is on whether the textchat plays a role during interaction, considering it is in competition not only with the audio modality but also with several nonverbal modalities; and on whether the textchat modality can serve for feedback provision on language form.This thesis seeks to contribute to the methodological considerations to allow research to move beyond speculative and anecdotal examples of multimodal pedagogical communication in synthetic worlds. A typology of nonverbal and verbal modalities is proposed, and then drawn upon, to extend a previous methodology suggested for multimodal transcription to interactions in synthetic worlds. Considering, within the fields of Social Sciences and Language Sciences, the more general research problem to render research data used for analyses visible and publically accessible, the study adopts a LEarning and TEaching Corpus (LETEC) methodological approach. Constituting a structured corpus allows for contextual analyses of the data collected during the 'Building Fragile Spaces' course.This research offers insights into how verbal participation increases with reference to the proxemic organisation of students, the customization of students' avatar appearance and an increased use of nonverbal acts. Concerning verbal production, the study shows how avatar movement in the nonverbal mode was used as a strategy to overcome verbal miscommunication when expressing direction and orientation and also the benefits of using the textchat modality for feedback on language form in order to support learners’ productions in the audio modality. In light of these results, the study suggests some considerations concerning the design of pedagogical activities for language learning within synthetic worlds.

The aim of this study is to offer a new perspective on both interpersonal communication andcomputer-mediated communication (CMC), by means of conducting a pragma-linguisticanalysis and comparison of a semi-threaded discussion forum and a fully threaded discussionforum; analysing features such as linguistic markers, dialogic listening, politeness, cooperation,elaborate or laconic greetings, farewell expressions and other conversational rituals. Aqualitative study was conducted, employing two methods of gathering data: (a) participantobservation and (b) document and material analysis. The major question for discussion in thisstudy is whether there are any differences with respect to linguistic and non-linguistic featuresbetween the semi-threaded and fully threaded forums? The study concludes that there aredifferences in linguistic and non-linguistic features between semi-threaded and fully threadedforums, but these differences are minimal and can more likely be attributed to the forum subjectmatter and social context than to the forum structure itself.

Cette recherche relève du domaine de la didactique du FLE et de l'usage de la communication médiée par ordinateur [CMO], plus particulièrement du clavardage, outil de communication synchrone à base textuelle. Notre recherche se place dans une perspective interactionnelle et acquisitionnelle en L2 en mettant l'accent sur la construction des discussions entre participants lors de séances de clavardage. Le public étudié est composé d'étudiants de nationalités variées en master ou doctorat dans des universités en France, et qui souhaitent améliorer la langue qu'ils doivent utiliser en milieu académique. Notre analyse du « discours-en-interaction par clavardage » a pour but d'étudier les interactions en tenant compte des spécificités de l'outil et du contexte de la discussion. En premier lieu, nous examinons la structure des énoncés en L2 au niveau de l'utilisation du lexique, des structures complexes et des marques transcodiques. En deuxième lieu, nous analysons l'utilisation des topogrammes dans un contexte académique et leurs diverses fonctions. Cette analyse montre la manière dont les apprenants se focalisent à la fois sur l'objet thématique de la discussion et sur la résolution des obstacles linguistiques ou discursifs auxquels ils sont confrontés lors des échanges. En dernier lieu, nous étudions la manière dont les apprenants construisent et co-construisent les discussions par clavardage. Les énoncés que l'apprenant construit à partir des discours de ses différents interlocuteurs lui permettent, tout en alimentant ses compétences pragmatiques, d'approfondir le sujet en discussion. Nous examinons également comment les savoirs sur les pratiques académiques naissent et se transforment au fil des interactions. Nous cherchons à montrer à la fois le bénéfice de l'utilisation du clavardage pour la recherche sur la langue d'apprenants avancés et son intérêt comme outil po! ur favoriser l'appropriation d'une L2. / This is a research in the teaching and learning of French as a foreign language and the use of CMC [computer mediated communication] using synchronous text-based CMC [computer mediated communication], viz chat. We analyze the construction of discussions between foreign students with an interactional and acquisitional perspective in order to discover its specificities. The target audience is enrolled in a French university at advanced levels [Master, Ph D…] and needs to improve their French as used in an academic context. In a « discourse analysis in chat interactions », we focus on specificities of this communication tool and of the discussion context. We first show the structure of learners' utterances, their use of lexical items and complex structures, and the influence of their other languages on their productions in French. Then, we analyze the use of « topogrammes » in an academic context and their different functions. We thus sho! w how learners focus on the thematic object of the discussion and the solving of linguistic or discourse obstacles they were faced with during the exchanges. We also study the way in which the learners construct and co-construct the discussions. The messages that they construct from their interlocutors' discourses allow them to develop the theme into a discussion and to improve his pragmatic competences. Finally, we examine how knowledge about academic practices appears and evolves during the interactions. Our work shows the benefits of the use of the chat for linguistic research about advanced learners and its interest as a communication tool in L2 acquisition.

Dans le contexte du développement durable, l’'utilisation des ressources renouvelables, biodégradable et peu toxique, est particulièrement recherchée. En particulier, la littérature montre que les molécules amphiphiles biosourcées avec une tête sucre, type glycolipides, sont d'excellents candidats pour substituer les tensioactifs pétrochimiques actuellement utilisés massivement en formulation. Pour limiter le criblage expérimental et orienter le choix des synthèses de telles molécules, une démarche prédictive à partir de l'analyse de la structure moléculaire permettrait d'anticiper les propriétés des molécules amphiphiles et d'identifier celles répondant à des propriétés spécifiques recherchées. L'objectif des travaux de thèse est de développer une méthodologie via la synthèse à façon avec modification graduelle de la structure, la caractérisation et l'analyse systématique de glycolipides, dans le but d'identifier des liens pertinents entre leurs propriétés amphiphiles et leurs caractéristiques structurales. Les données expérimentales générées doivent permettent d'établir une base de données comparables et fiables, nécessaire pour le développement de modèles 1 prédictifs. Les résultats ont mis en évidence l'influence significative de certains paramètres de structure sur j les propriétés physico-chimiques, avec des tendances claires, autrement difficiles à observer à partir des données globales non-comparables de la littérature. Ce travail a également démontré l'importance de prendre en considération le comportement des molécules amphiphiles dans l'eau, via la connaissance de leur diagramme de phase, afin de définir sans ambiguïté certaines propriétés telles que la CMC. / In the context of sustainable development, the use of biodegradable and low toxic renewable resources is particularly important. ln particular, the literature shows that the bio-based amphiphilic molecules with a sugar head, or the glycolipids, are excellent substitutes of the petrochemical surfactants used massively in current formulations. To limit the experimental screening and to orient the choice of the syntheses of such molecules, a predictive approach based on the analysis of the molecular structure would make it possible to anticipate the properties of the amphiphilic molecules and to identify those with specific properties. The objective of this work is to develop a methodology through systematic syntheses, characterizations and analyses of glycolipids with gradual structural modifications, with the aim of identifying relevant links between heir amphiphilic properties and their structural characteristics. The obtained experimental data should make it possible to establish a comparable and reliable database, necessary for the development of predictive models. The results showed the significant influence of some structural parameters on the physico-chemical properties with clear trends, which are otherwise difficult to observe by using the non-comparable data collected from the literature. This work also demonstrated the importance of considering the behavior of amphiphilic molecules in water, through knowledge of their phase diagram, which allows for the unambiguous definition of certain properties like the CMC.

The impact of computer-mediated communication (CMC) on relational behavior is a topic of increasing interest to communication scholars (McQuillen, 2003; Tidwell & Walther, 2002). One of the most interesting issues that CMC raises concerns the impact of CMC on relational maintenance and development. Using dialectical theory, social exchange theory, social information processing theory, and the hyperpersonal perspective as theoretical frameworks, this study used quantitative and qualitative analyses to identity potential effects of CMC on relationships. Study 1 (n=317) examined the effects of CMC on relational closeness, satisfaction, and social support. Study 2 (n=196) explored the reasons individuals provide for privileging computer-mediated forms of communication, and the perceived effects of using CMC in relational communication. Results indicated that quality of CMC predicted increased perceptions of social support and relationship satisfaction. Results further suggested that CMC enabled participants to manage more effectively relational tensions of autonomy-connection and openness-closedness. Specifically, individuals used CMC to retain higher levels of conversational control, and to maintain greater numbers of relationships with decreased levels of investment. This paper concludes with a discussion of implications and directions for future research.

Master thesis Testing of Directional Earth Fault Protections Using the Experimentally Obtained Fault Records deals with the protective functions of earth fault protections during earth faults in compensated medium voltage distribution network and their testing options. At the beginning of the thesis we charakterize operation of medium voltage distribution system in general. We begin with definition and characteristics of earth fault and its compartmentalization by the type of the fault, size of the transition resistance and duration. We also mention grounding methods of node winding transformer on medium voltage distribution network and we describe the most common of them in detail, i.e. network grouded through the arc suppression coil and its operation with automatic switching auxiliary resistor. In this part of the thesis we discuss the localization of the earth fault using passive static methods in compensated systems, which include wattmetric, admittance and conductance method. In next section we deal with the fault records stored in COMTRADE file format, its structure and all elements of its configuration and data file. We create and describe an example of converting ADF file format, recorded by Yokogawa oscilloscope fault recorder, into COMTRADE file format using Microsoft Excel program and M-File created in the MATLAB program. In the practical part we introduce workspace devices and software, which includes secondary testing equipment OMICRON CMC 256plus and its software OMICRON Test Universe with Advance Transplay test module, we further describe multifunctional earth fault protection RYo from PROTECTION & CONSULTING, s. r. o. and machine terminal REM 543 from ABB and their protective functions. The last part describes the actual testing of parallel connected earth fault protection with COMTRADE fault records by Advance Transplay test module in the OMICRON Test Universe. In the conclusion we describe evaluation of the suitability of each protective functions of earth fault protection in a variety of sizes the transition resistance at the earth fault location.

This work describes three alternative processes for producing microfibrillated cellulose (MFC) in which pulp fibres are first pre-treated and then homogenized using a high-pressure homogenizer. In one process, fibre cell wall delamination was facilitated with a combined enzymatic and mechanical pre-treatment. In the two other processes, cell wall delamination was facilitated by pre-treatments that introduced anionically charged groups into the fibre wall, by means of either a carboxymethylation reaction or irreversibly attaching carboxymethyl cellulose (CMC) onto the fibres. All three processes are industrially feasible and enable production with low energy consumption. Using these methods, MFC can be produced with an energy consumption of 500–2300 kWh/tonne, which corresponds to a 91–98% reduction in energy consumption from that presented in earlier studies. These materials have been characterized in various ways and it has been demonstrated that the produced MFCs are approximately 5–30 nm wide and up to several microns long. / <p>QC 20120928</p>

Syftet är att undersöka hur ett antal gymnasielärare som undervisar i svenska ser på datortillgång och datoranvändning, samt vilka krav de ställer på elevernas datoranvändning i kursen Svenska A. Undersökningen genomfördes via en webbenkät, vilken distribuerades under mars 2009. Resultatet av webbenkäten ställs mot beskrivningar av förutsättningar för skrivande och aktuella styrdokument. Tillgången på lärardatorer är otillräcklig och tillgången på elevdatorer är ännu mera otillräcklig. Datormedierad kommunikation används för att effektivisera undervisningen och för att nå eleverna med information. En majoritet av lärarna i undersökningen har inte erbjudits kompetensfortbildning inom området datormedierad kommunikation av sin arbetsgivare. I kursen Svenska A erbjuds eleverna varierande datortillgång, allt från varje lektion till en gång per kurs. Lärarnas krav på elevernas datorkompetens i kursen varierar mellan ”inga krav” och omfattande krav. I diskussionen belyser jag hur ny teknik assimileras av skola och undervisning och sätter in mina resultat i en tidskontext. / The purpose of my investigation is to study the view of supply of computers and the use of computers among a num¬ber of senior high school teachers, teaching Swedish. I also investigate their demands on pupils and their use of computers in the course “Svenska A”. My web inquiry was distributed during March 2009. The results of the inquiry have been compared with descriptions of requirements for writing and with former and present curricula. The supply of computers for teachers is insufficient and the supply of computers for pupils is even more so. Communication mediated by computer is being used to give information to pupils and to make teaching more efficient. A majority of the teachers have not been offered further training by their employers within the field of communication mediated by computer. In the course “Svenska A” pupils are being offered to use computers in varying degrees, from once per course till every lesson. The teachers’ claims on the pupils’ competence in their use of computers vary from “no demands” to wide demands. In the discussion I shed light on how new technology is being assimilated by schools and education. I also insert my results in a context of time.
