En recherche d’information, les documents sont le plus souvent considérés comme des "sacs-de-mots". Ce modèle ne tient pas compte de la structure temporelle du document et est sensible aux bruits qui peuvent altérer la forme lexicale. Ces bruits peuvent être produits par différentes sources : forme peu contrôlée des messages des sites de micro-blogging, messages vocaux dont la transcription automatique contient des erreurs, variabilités lexicales et grammaticales dans les forums du Web. . . Le travail présenté dans cette thèse s’intéresse au problème de la représentation de documents issus de sources bruitées.La thèse comporte trois parties dans lesquelles différentes représentations des contenus sont proposées. La première partie compare une représentation classique utilisant la fréquence des mots à une représentation de haut-niveau s’appuyant sur un espace de thèmes. Cette abstraction du contenu permet de limiter l’altération de la forme de surface du document bruité en le représentant par un ensemble de caractéristiques de haut-niveau. Nos expériences confirment que cette projection dans un espace de thèmes permet d’améliorer les résultats obtenus sur diverses tâches de recherche d’information en comparaison d’une représentation plus classique utilisant la fréquence des mots.Le problème majeur d’une telle représentation est qu’elle est fondée sur un espace de thèmes dont les paramètres sont choisis empiriquement.La deuxième partie décrit une nouvelle représentation s’appuyant sur des espaces multiples et permettant de résoudre trois problèmes majeurs : la proximité des sujets traités dans le document, le choix difficile des paramètres du modèle de thèmes ainsi que la robustesse de la représentation. Partant de l’idée qu’une seule représentation des contenus ne peut pas capturer l’ensemble des informations utiles, nous proposons d’augmenter le nombre de vues sur un même document. Cette multiplication des vues permet de générer des observations "artificielles" qui contiennent des fragments de l’information utile. Une première expérience a validé cette approche multi-vues de la représentation de textes bruités. Elle a cependant l’inconvénient d’être très volumineuse,redondante, et de contenir une variabilité additionnelle liée à la diversité des vues. Dans un deuxième temps, nous proposons une méthode s’appuyant sur l’analyse factorielle pour fusionner les vues multiples et obtenir une nouvelle représentation robuste,de dimension réduite, ne contenant que la partie "utile" du document tout en réduisant les variabilités "parasites". Lors d’une tâche de catégorisation de conversations,ce processus de compression a confirmé qu’il permettait d’augmenter la robustesse de la représentation du document bruité.Cependant, lors de l’élaboration des espaces de thèmes, le document reste considéré comme un "sac-de-mots" alors que plusieurs études montrent que la position d’un terme au sein du document est importante. Une représentation tenant compte de cette structure temporelle du document est proposée dans la troisième partie. Cette représentation s’appuie sur les nombres hyper-complexes de dimension appelés quaternions. Nos expériences menées sur une tâche de catégorisation ont montré l’efficacité de cette méthode comparativement aux représentations classiques en "sacs-de-mots". / In the Information Retrieval field, documents are usually considered as a "bagof-words". This model does not take into account the temporal structure of thedocument and is sensitive to noises which can alter its lexical form. These noisescan be produced by different sources : uncontrolled form of documents in microbloggingplatforms, automatic transcription of speech documents which are errorprone,lexical and grammatical variabilities in Web forums. . . The work presented inthis thesis addresses issues related to document representations from noisy sources.The thesis consists of three parts in which different representations of content areavailable. The first one compares a classical representation based on a term-frequencyrepresentation to a higher level representation based on a topic space. The abstractionof the document content allows us to limit the alteration of the noisy document byrepresenting its content with a set of high-level features. Our experiments confirm thatmapping a noisy document into a topic space allows us to improve the results obtainedduring different information retrieval tasks compared to a classical approach based onterm frequency. The major problem with such a high-level representation is that it isbased on a space theme whose parameters are chosen empirically.The second part presents a novel representation based on multiple topic spaces thatallow us to solve three main problems : the closeness of the subjects discussed in thedocument, the tricky choice of the "right" values of the topic space parameters and therobustness of the topic-based representation. Based on the idea that a single representationof the contents cannot capture all the relevant information, we propose to increasethe number of views on a single document. This multiplication of views generates "artificial"observations that contain fragments of useful information. The first experimentvalidated the multi-view approach to represent noisy texts. However, it has the disadvantageof being very large and redundant and of containing additional variability associatedwith the diversity of views. In the second step, we propose a method based onfactor analysis to compact the different views and to obtain a new robust representationof low dimension which contains only the informative part of the document whilethe noisy variabilities are compensated. During a dialogue classification task, the compressionprocess confirmed that this compact representation allows us to improve therobustness of noisy document representation.Nonetheless, during the learning process of topic spaces, the document is consideredas a "bag-of-words" while many studies have showed that the word position in a7document is useful. A representation which takes into account the temporal structureof the document based on hyper-complex numbers is proposed in the third part. Thisrepresentation is based on the hyper-complex numbers of dimension four named quaternions.Our experiments on a classification task have showed the effectiveness of theproposed approach compared to a conventional "bag-of-words" representation.

In recent years, a considerable amount of research has been conducted in modelling non-functional requirements (NFR) or Quality Requirements (QR). However, in comparison with functional requirements (FR) modelling, QR models are still immature and have not been widely adopted. The fundamental reason for this shortfall outlined in this thesis is that the existing QR modelling approaches have not adequately considered the challenging nature of QRs. In this thesis, this limitation is addressed through integrating QR modelling with FR modelling in a multi-perspective modelling framework. This framework, thus called QRMF (Quality Requirements Modelling Framework), is developed offering a process-oriented approach to modelling QR from different views and at different phases of requirement. These models are brought together in a descriptive representation schema, which represents a logical structure to guide the construction of requirement models comprehensively and with consistency. The research presented in the thesis introduces a generic meta-meta model for QRMF to aid understanding the abstract concepts and further guide the modelling process; it offers a reference blueprint to develop a modelling tool applicable to the framework. QRMF is supported by a modelling process, which guides requirement engineers to capture a set of complete, traceable and comprehensible QR models for software system. The thesis presents a case study, which evaluates the practicality and applicability of the QRMF. Finally, the framework is evaluated theoretically, through comparing and contrasting related approaches found in the literature.

"Down and Out in Paris and London" is typically perceived as non-political. Orwell's first book, it examines his life with the poor in two cities. Although on the surface "Down and Out" seems not to be about politics, Orwell covertly conveys a political message. This is contrary to popular critical opinion. What most critics fail to acknowledge is that Orwell wrote for a middle- and upper-class audience, showing a previously unseen view of the poor. In this he suggests change to the policy makers who are able to bring about improvements for the impoverished. "Down and Out" is often ignored by both critics and readers of Orwell. With an examination of Orwell's politicizing background, and of the way he chooses to present himself and his poor characters in "Down and Out," I argue that the book is both political and characteristic of Orwell's later work.

Denna kvalitativa studies syfte är att lyfta fram vikten av att arbeta våldsförebyggande i lågstadiet och vilka hinder som kan finnas. Att arbeta våldsförebyggande handlar om att agera innan något hänt och att lära ut redskap och definitioner av vad våld är och innebär. Utifrån Vygotskijs syn på inlärning har materialet tolkats för att försöka få fram om och i så fall på vilket sätt lärarnas syn på våld påverkar deras våldspreventiva arbete. Som stöd i teoridelen har vi också använt oss av våldspyramiden samt normaliseringsprocessen, detta för att ytterligare försöka förstå det komplexa ämne våld är. Skolans syfte är inte enbart att lära ut skolämnen utan är också en plats där barn skall vara trygga och kunna tillgodose sig den kunskap som förmedlas.Vi vill med denna uppsats undersöka hur lärare i lågstadiet ser på våld mellan elever och om deras syn påverkar det våldsförebyggande arbetet i skolan. Vi vill också försöka bidra men att öka kunskapen kring våldets komplexitet och vad skolan och lärare kan göra för att försöka minska detta. Vi har intervjuat lärare för att försöka identifiera på vilket sätt de arbetar våldsförebyggande och vad de anser vara våld men också försöka få reda på om lärarnas syn på våld kan påverka sättet de arbetar våldsförebyggande. / The purpose of this qualitative study is to highlight the importance of working with violence prevention in primary school and what obstacles may exist. Working with violence prevention is about acting before something has happened and teaching tools and definitions of what violence is and means. Based on Vygotsky's view of learning, the material has been interpreted to try to find out if and if so how teachers' views on violence affect their violence prevention work. As support in the theory part, we have also used the violence pyramid as well as the normalization process, this to further try to understand the complex subject of violence. The purpose of the school is not only to teach school subjects, but is also a place where children should be safe and able to satisfy the knowledge that is conveyed.With this paper, we want to investigate how primary school teachers view violence between pupils and whether their views affect violence prevention in schools. We also want to try to contribute but to increase knowledge about the complexity of violence and what the school and teachers can do to try to reduce this. We have interviewed teachers to try to identify how they work with violence prevention and what they consider to be violence, but also to try to find out whether teachers' views on violence can affect the way they work with violence prevention.

This study investigates Swedish upper-secondary teachers’ views and reported practices regarding pronunciation instruction in the English-as-a-foreign-language classroom. It adopts a mixed-method design, analysing qualitative data collected from a focus-group interview (N=4) and quantitative data collected from an online survey (N=54).  To investigate the views and reported practices of teachers, the following research questions were posed:  1. What are the views and attitudes of English teachers in the Swedish upper-secondary school regarding pronunciation and pronunciation instruction?  2. How do English teachers in the Swedish upper-secondary school describe their own practices in pronunciation instruction?  Results indicate that teachers generally value comprehensibility as the most important aim of pronunciation instruction. However, a native-like accent still seems to be highly valued, and nativeness norms still seem to affect teachers’ views and practices to some extent. Finally, our findings indicate that teachers spend very little time on pronunciation teaching in general, and they highlight that other aspects of language instruction are more important.

The tool allows distribution of credit for the conversion to various marketing activities. So-called attribution modelling is concerned. The distribution of conversion is described by the models, except those most famous (first interaction model, last interaction model, linear model), that allow to create any distribution of conversion to several marketing activities. The use of this tool may be useful in the surveys of the effectiveness of marketing activities.

Cette recherche porte sur l'évolution de la critique poétique arabe moderne, elle combine deux volets, l'un diachronique et l'autre analytique. D'une part, elle exAmīne l'histoire de cette évolution qui en l'espace d'un siècle a été impressionnante et d'autre part elle analyse ce phénomène qui dans l'histoire littéraire mondiale ne s'est jamais produit sur une durée aussi courte. La période de la nahḍa a commencé durant la deuxième moitié du XIXème siècle et a duré jusqu'aux années trente du XXème siècle. La littérature arabe a été ébranlée par une multitude de mouvements à la fois conservateurs et modernistes , mouvements qui ont tantôt cohabité et tantôt se sont opposés ; la poésie, en particulier a comblé un retard de cinq siècles, comme en témoignent le nombre de poèmes et de recueils publiés et la multiplication des styles et des écoles littéraires.Durant un siècle et souvent pendant la même période, nous pouvons découvrir des poètes classiques, néoclassiques, romantiques, symboliques et réalistes. La production poétique a aussi été très variée et a respecté les règles classiques relatives à la mesure et aux rimes tout en affichant un retour vers la forme classique pour affirmer la maîtrise. Puis, l'inspiration du "muwaššaḥ" a fait son apparition et s'est détourné de l'exigence de la forme traditionnelle avec quelques tentatives pour écrire de la poésie libre et en prose avec de nouvelles mesures et enfin l'arrivée de la poésie blanche...etc.Toutes ces tentatives pour se rattacher à un courant n'ont pas échappé à la critique qui a parfois ouvert la voix aux poètes et a parfois précédé la production poétique et qui a subi la pression moderniste en essayant de la rejoindre; la critique a puisé dans les écrits anciens et en même temps une ouverture sur la critique occidentale. La révolution contre le traditionalisme est lancée avec des écoles qui ont revendiqué une coupure avec l'héritage des classiques. D'autres courants vont résister à l'influence européenne en prenant pour prétexte le combat contre le colonialisme occidental. Ces courants très résolus ont défendu l'attachement à l'ancienne école en invoquant la pureté de la langue du Coran, la richesse de cet héritage et le fait que cette modernisation peut susciter des théories inadaptées à la réalité sociale et culturelle. Nous tentons dans cette étude de présenter et d'analyser les quatre étapes que la poésie et la critique poétique ont traversées durant cette période :- L'étape de l'imitation médiocre. - L'étape de l'imitation cohérente et éloquente.- L'étape de l'innovation liée à la ferveur nationaliste.- L'étape de l'innovation liée à un sentiment de liberté individuelle. / The research work presented in this manuscript focuses on the evolution of the modern Arab poetry critic. The work is two fold: one diachronic and the other analytical. We detail on one hand the history of such evolution, which, in the space of a century, has been quite impressive, and on the other hand,we analyze this phenomenon, which has never occurred in the world literacy history over such a short time span. The period of the nahda started in the second half of the XIXth century and lasted up to the last years of the XXth century. The history of the Arab literature has been shattered by numerous events, at the same time conservative and modernist. Those events were at times contiguous and at times opposite: poetry in particular, has caught up with a major delayof nearly five centuries, as witnessed by the number of poems and collections published,and as well asby the multiplication of styles and literacy schools.Over the span of a century, and often within the same period, one may discoverand study classical, neoclassical, romantic, symbolic as well as realist poets. Furthermore, the poetry production has also been diversein styles, but at the same time addressed the classical rules related to the measure and the rhymes, while displaying a reversal movement towards the classical form, mainly to show and prove mastering skills. Then, the inspiration of the "muwaššaḥ" appeared and has strayed away from the requirements of the traditional form, with a few attempts to write free poetry as well as prose with new measures, and eventually came to the birth of white poetry,… etc.All those various efforts attempting atreclaiming a main historic literacy flow has definitely not been overlooked by the critic, which at times has brought forward poets, and at times has even preceded the poetic production which has undergone through the modernistic pressure by trying to join that same flow; the critique has drawn in the ancient scripts and at the same time in the opening into the occidental critic. The revolution against traditionalism has been launched with various schools who have claimed a split with the inheritance of the classics.Other currents have resisted to the European influence by pretexting a fight against occidental colonialism. These very resolute currents have defended the attachment to the ancient school by invoking the purity of the language of the Koran, the richness of this heritage and the fact that this modernization can produce ill-adapted theories to the social and cultural reality.We attempt in this work to present and analyze the four stages, through which poetry and the poetry critic have gone through during the past century:1) The stage of mediocre imitation 2) The stage of coherent and eloquent imitation, 3) The stage of innovation linked to a nationalist fervor4) And eventually the stage of innovation linked to a feeling of individual freedom.

Das computergrafische Abbildungsverfahren zur Verwirklichung von dreidimensionalen Darstellungen ist ein wichtiges Instrument für die Gestaltung interaktiver 3D-Benutzerschnittstellen. Die Betrachtung von Projektionsverfahren abseits des bisher angestrebten Fotorealismus dokumentiert, dass durch nichtlineare und multiperspektivische Darstellungen spezifische Eigenschaften und Charakteristiken eines Datenbestandes vermittelt werden können. Dabei wird deutlich, dass konzeptionelle und methodische Unzulänglichkeiten den erfolgreichen Einsatz von unkonventionellen linearen sowie nichtlinearen Darstellungsformen in 3D-Anwendungen bisher einschränken. In dieser Arbeit werden daher Darstellungstechniken analysiert und systematisiert, die durch den computergrafischen Projektionsvorgang erzeugt und für die Verwirklichung von Visualisierungszielen eingesetzt werden können. Ferner werden für den spezifischen Einsatz von komponierten Visualisierungsverfahren in 3D-Benutzerschnittstellen Gestaltungshinweise formuliert. Darauf aufbauend erfolgt die Einführung einer modellbasierten Vorgehensweise, durch welche die systematisierten Visualisierungsformen in einem methodischen und ferner entwurfsmustergestützten Entwurfsprozess zur Entwicklung interaktiver 3D-Interfaces eingebunden und weiterhin in einer interaktiven 3D-Anwendung eingesetzt werden können.

ENGLISH ABSTRACT This dissertation is focused on Prague in views in literary works of post-february exile authors, which emigrated after year 1948: Egon Hostovský, Zdeněk Němeček and Jiří Kovtun. The picture of Prague, which we can (re)construct from their works, is different in each case. In the novel Nezvěstný of Egon Hostovský dominate followings motives: gray, weak contours, theatricality, panoptic and a metaphorical description of February Prague. The main features of the works of Zdeněk Nemeček are: close relationship between teller and main character, short dialogs, view from above, sad feelings and feeling of separation. Konvtun's work named Pražská ekloga is specific with irony (it is evidently a product of considerable time span from the other described events), naturalistic features and war atmosphere. The authors associate a considerable relationship to Prague and their contributions to the programme "Slovo a svět" of the Radio Free Europe, in spite of their different life stories and poetics. The main theoretic result of the diploma is city poetology of Daniela Hodrová ("Citlivé město"). Interpretive interest isn't limited only to the mentioned literary works, in the diploma are also considered data from the periodic newspapers and other professional literature. The objective of the...
